ITEM 1. Business.

GENERAL

      We are a  biopharmaceutical  company engaged in the clinical  development,
manufacture,  marketing and  distribution  of new drug entities based on natural
immune system enhancing technologies for the treatment of viral and immune based
chronic disorders.  We were founded in the early 1970s, as a contract researcher
for the National  Institutes of Health.  Since that time, we have  established a
strong foundation of laboratory, pre-clinical, and clinical data with respect to
the development of nucleic acids to enhance the natural antiviral defense system
of the human body and to aid the  development  of  therapeutic  products for the
treatment  of  chronic  diseases.  We own a U.S.  Food and  Drug  Administration
("FDA") approved GMP (good manufacturing practice) manufacturing facility in New
Jersey.


                                       1


      Our flagship  products  include  Ampligen(R)  and Alferon N  Injection(R).
Ampligen(R) is an experimental drug currently  undergoing  clinical  development
for  the  treatment  of:  Myalgic   Encephalomyelitis/Chronic  Fatigue  Syndrome
("ME/CFS" or "CFS"),  and HIV. In August 2004, we completed a Phase III clinical
trial ("AMP 516")  treating over 230 ME/CFS  patients with  Ampligen(R)  and are
presently in the process of preparing a new drug application ("NDA") to be filed
with the FDA. Over its developmental  history,  Ampligen(R) has received various
designations,   including  Orphan  Drug  Product  Designation  (FDA),  Emergency
(compassionate) Cost Recovery Sales Authorization (FDA) and "promising" clinical
outcome  recognition based on the evaluation of certain summary clinical reports
(AHRQ, Agency Health Research Quality).  In response to our application for Fast
Track Designation,  the FDA has requested additional  information to support the
potential  of  Ampligen(R)  to treat a  serious  or life  threatening  aspect of
ME/CFS.  The  definition  of the  "seriousness  of a  condition",  according  to
Guidance  for  Industry  documents  published  in  July,  2004 is "a  matter  of
judgment,  but  generally  based on its  impact  on such  factors  as  survival,
day-to-day  functioning,  or the likelihood that the disease, if left untreated,
will  progress  from a less severe  condition  to a more serious  one".  The FDA
requested  a  "complete  and  audited  report of the Amp 516 study to  determine
whether  Ampligen(R)  has a clinically  meaningful  benefit on a serious or life
threatening  aspect  of ME/CFS in order to  evaluate  whether  the Amp 516 study
results  do or do not  support  a "fast  track  designation".  The FDA has  also
invited us to include a schedule for completion of all ME/CFS studies as well as
a proposed  schedule  for our NDA  submission.  Because  we  believe  our ME/CFS
studies are complete, we intend to request a pre-NDA meeting to obtain advice on
preparing and  submitting  our NDA,  which may eliminate the need for Fast Track
Designation. Meanwhile, we continue with our existing ongoing efforts to prepare
a  complete  and  audited   report  of  our  various   studies,   including  the
well-controlled  Amp 516 study.  We are using our best  efforts to complete  the
requisite  reports  including the hiring of additional  staff and various expert
medical/regulatory  consultants,  but can provide no assurance as to whether the
outcome of this large data  collection  and filing  process  (approximately  750
patients,  treated more than 45,000  times) will be  favorable  or  unfavorable,
specifically  with  respect  to  the  FDA's  perspective.  We  plan  to  use  an
independent  contractor to file the NDA  electronically to facilitate the review
by the FDA.  Also, we can provide no guidance as to the tentative  date at which
the compilation and filing of such data will be complete, as significant factors
are  outside  our  control  including,   without  limitation,  the  ability  and
willingness of the independent clinical  investigators to complete the requisite
reports at an acceptable  regulatory  standard,  the ability to collect overseas
generated data, and the ability of Hollister-Stier  facilities to interface with
our own New  Brunswick  staff/facilities  to meet the  manufacturing  regulatory
standards.  In addition,  Ampligen(R)  is  undergoing  pre-clinical  testing for
possible treatment of avian influenza ("bird flu").

      Alferon N  Injection(R)  is the  registered  trademark for our  injectable
formulation  of natural alpha  interferon,  which is approved by the FDA for the
treatment  of genital  warts.  Alferon N  Injection(R)  is also in  pre-clinical
development for treating Multiple Sclerosis and West Nile Virus ("WNV").

      With the threat of an avian influenza pandemic rising and health officials
warning that the virus could develop  resistance to current flu treatments,  the
pursuit of a cost-effective  and capable  co-administered  immunotherapeutic  to
existing  antivirals  and vaccines has become  critical.  This  combination  may
permit the use of lower  dosages  and fewer  injections  of the  antivirals  and
vaccines  used  to  combat  avian  flu,  thereby  decreasing  the  cost  of both
immunization programs and treatment programs for the full-blown disease.

      In  antimicrobial  (antibacterial)  therapy,  which  is  the  best-studied
clinical  model,   synergistic   drug   combinations   may  result  in  curative
conditions/outcomes,  often not observed  when the single drugs are given alone.
In the case of avian influenza where global drug supplies are  presumptively  in
very  limited  supply  relative  to  potential  needs,  therapeutic  synergistic
combinations  could not only affect the disease outcome,  but also the number of
individuals able to access therapies.


                                       2


      We recently  announced that true therapeutic  synergy had been observed in
the interaction  between  Ampligen(R) and Tamiflu in the inhibition of the avian
influenza  virus.  The same  synergy  was  observed in the  interaction  between
Ampligen(R)  and Relenza in lab tests in December  2005.  Cell  destruction  was
measured in vitro using different drug combinations. True therapeutic synergy is
defined by mathematical  equations  which indicate that the  therapeutic  effect
observed is in fact greater than the  expected  arithmetic  sum of the two drugs
working   independently,   and  is  referred  to  by   pharmacologists   as  the
"Chou/Talalay" equations developed at Johns Hopkins University.

      In  a  recently  reported  study  from  a  vaccine  group  in  Japan,  the
incorporation of poly I: poly C (dsRNA) into a nasal  administration of a killed
influenza A preparation  converted a poorly  immunogenic  response into a highly
efficacious  vaccine in  protection  of mice from  lethal  infection  from human
influenza A.  Ampligen(R)  is a dsRNA which  currently is undergoing  testing in
this animal model.

      Recently, at the fourth annual Biodefense Research Meeting of the American
Society of  Microbiology  held in  Washington,  D.C.,  we  presented  results of
laboratory  testing  that  showed  our two  investigational  immunotherapeutics,
Ampligen(R) and Alferon(R),  are potentially  useful against H5N1, or avian flu,
virus.  The pre-clinical  research  indicates that  Ampligen(R),  a specifically
configured  double-stranded RNA, can provide  cross-protection against avian flu
viral mutations as well as boost the  effectiveness of Tamiflu and Relenza,  the
only two drugs  formally  recognized  for  combating  bird flu, up to 100 times.
Other lab tests, in healthy human volunteers,  indicate that Alferon(R) LDO (Low
Dose Oral), a new delivery form of an anti-viral with prior regulatory  approval
for a category of sexually transmitted diseases, can stimulate genes that induce
the production of interferon and other immune compounds,  key building blocks in
the body's defense  system.  The studies were conducted in conjunction  with the
National Institute of Infectious Diseases of Japan.

      We have  recently  entered  into an  agreement  with  Defence  R&D Canada,
Suffield  ("DRDC  Suffield"),  an agency of the Canadian  Department of National
Defence,  to evaluate the  antiviral  efficacy of our  experimental  therapeutic
Ampligen(R) and Alferon(R) for protection  against human  respiratory  influenza
virus  infection in well validated  animal  models.  DRDC Suffield is conducting
research and development of new drugs that could potentially  become part of the
arsenal of existing  antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the  respiratory  influenza
virus infection on a mouse-adapted strain of human influenza.  DRDC Suffield has
already conducted  extensive research in the use of liposome delivery technology
to enhance the antiviral activity of a closely-allied Ampligen(R) analogue, Poly
ICLC (an immunomodulating  dsRNA) which is very similar to Ampligen(R).  Results
suggest that ribonucleic  acid-based drugs have the ability to elicit protective
broad-spectrum  antiviral  immunity against various pathogenic  viruses.  Hence,
there is the potential for efficacy to be maintained against mutating strains of
an influenza virus.  Liposomes,  a carrier system for nucleic  acid-based drugs,
have  shown an  ability  to protect  these  drugs  against in vivo  degradation,
delivering  them to  intracellular  sites of  infection,  thereby  reducing  any
toxicity and  prolonging  their  therapeutic  effectiveness.  Protection  can be
afforded for 21 days with two doses of dsRNA. It is believed that in humans with
active flu infection, Tamiflu, given twice daily, may ameliorate symptoms.


                                       3


      We have over 100  patents  worldwide  with 9  additional  patents  pending
comprising our intellectual  property.  We continually review our patents rights
to  determine  whether  they have  continuing  value.  Such  review  includes an
analysis of the  patent's  ultimate  revenue  and  profitability  potential.  In
addition,  management's  review  addresses  whether each patent continues to fit
into  our  strategic  business  plans.  We have a fully  commercialized  product
(Alferon N Injection(R)), and a GMP certified manufacturing facility.

      In March 2004, we completed the  step-by-step  acquisition from Interferon
Sciences,  Inc.  ("ISI")  of ISI's  commercial  assets,  Alferon N  Injection(R)
inventory, a worldwide license for the production,  manufacture,  use, marketing
and  sale  of  Alferon  N  Injection(R),  as  well  as,  a  43,000  square  foot
manufacturing  facility in New Jersey and the  acquisition  of all  intellectual
property  related to Alferon  Injection(R).  Alferon N Injection(R) is a natural
alpha  interferon  that has been approved by the FDA for commercial sale for the
intra-lesional  treatment of refractory or recurring  external  genital warts in
patients 18 years of age or older.  The acquisition was completed in Spring 2004
with the acquisition of all world wide commercial rights.

      We completed  the  transfer and  consolidation  of our  Rockville  Quality
Assurance Lab and equipment into our New Brunswick  facility in 2005. We believe
this newly  consolidated  lab will  provide more  efficiency  with regard to the
quality assurance needs for both Ampligen(R) and Alferon N Injection(R).

      On December 9, 2005, we executed a Supply  Agreement with  Hollister-Stier
Laboratories LLC of Spokane,  Washington  ("Hollister-Stier"),  for the contract
manufacturing of Ampligen(R) for a five year term.  Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier  will formulate and bottle
the  Ampligen(R).  In November  2005,  we paid $100,000 as a deposit in order to
initiate the  manufacturing  project.  This deposit was expensed as research and
development  during  the  4th  Quarter  2005.  The  achievement  of the  initial
objectives  described  in  the  agreement,   in  combination  with  our  polymer
production facility under construction in New Brunswick,  N.J., may enable us to
manufacture the raw materials for approximately  10,000 doses of Ampligen(R) per
week. We executed a confidentiality  agreement with Hollister-Stier;  therefore,
we commenced the transfer of our  manufacturing  technology to  Hollister-Stier.
Currently,  Hollister-Stier  has  completed  two  pilot  manufacturing  runs  of
Ampligen(R) for stability testing.

      On February 8, 2006, we executed a Manufacturing and Safety Agreement with
Hyaluron, Inc. ("Hyaluron") of Burlington,  Massachusetts,  for the formulation,
packaging and labeling of Alferon N Injection(R).  Pursuant to the Agreement, we
will supply raw  materials  in  sufficient  quantity  and provide any  pertinent
information to the project.

      We  outsource   certain   components  of  our  research  and  development,
manufacturing,  marketing and distribution  while  maintaining  control over the
entire process through our quality  assurance group and our clinical  monitoring
group.


                                       4


      The  installation  of a  raw  material  production  line  within  our  New
Brunswick  facility has been completed and is now in production.  The production
of Ampligen(R)  raw materials in our own facilities has obvious  advantages with
respect to overall control of the  manufacturing  procedure of Ampligen(R)'s raw
materials,  keeping  costs down and  controlling  regulatory  compliance  issues
(other  parts of our 43,000 sq.  ft.  wholly  owned FDA  approved  facility  are
already in compliance  for Alferon N Injection(R)  manufacture).  This will also
allow us to obtain Ampligen(R) raw materials on a more consistent  manufacturing
basis.  As of April  30,  2006,  we have  capitalized  approximately  $1,400,000
towards the  construction  and  installation  of this production line at our New
Jersey  facility.  We expect the first lot of  Ampligen(R)  raw  material  to be
produced in the second quarter 2006. We estimate the total cost of  establishing
this  production  line  to be  $1,900,000,  including  modifications  to our New
Brunswick  facility.  We have  also  identified  three  manufacturers  to expand
polymer manufacture,  if necessary,  and obtained preliminary proposals from two
and have initiated discussions with the third.

      Since the  completion  of our AMP 516 ME/CFS Phase III clinical  trial for
use of  Ampligen(R)  in the treatment of ME/CFS we have received  inquiries from
and, under confidentiality  agreements, are having dialogue with other companies
regarding marketing opportunities. No proposals or agreements have resulted from
the dialogue, nor can we be assured that any proposals or agreements will result
from these inquiries.

our FDA approved  natural  interferon  product,  Alferon N Injection(R)  and our
experimental liquid natural interferon LDO.

      Ampligen(R)

      Nucleic acid compounds  represent a potential new class of  pharmaceutical
products that are designed to act at the molecular  level for treatment of human
diseases.  There are two forms of nucleic acids,  DNA and RNA. DNA is a group of
naturally  occurring   molecules  found  in  chromosomes,   the  cell's  genetic
machinery.  RNA is a group of naturally occurring  informational molecules which
orchestrate a cell's  behavior and which regulate the action of groups of cells,
including the cells,  which comprise the body's immune  system.  RNA directs the
production  of proteins and  regulates  certain cell  activities  including  the
activation of an otherwise  dormant  cellular  defense against virus and tumors.
Our  double-stranded,  specifically  configured,  RNA drug product,  trademarked
Ampligen(R),  which is  administered  intravenously,  is (or has  been) in human
clinical  development for various disease  indications,  including treatment for
ME/CFS, HIV, renal cell carcinoma and malignant melanoma.

      Our proprietary  development drug technology including Ampligen(R),  which
utilizes specially configured ribonucleic acid ("RNA") is currently protected by
more than 100 patents worldwide with 9 additional patent applications pending to
provide further proprietary protection in various international markets. Certain
patents apply to the use of Ampligen(R)  alone and certain  patents apply to the
use of Ampligen(R) in combination with certain other drugs.  Some composition of
matter patents pertain to other new medications  which have a similar  mechanism
of action.  During  2005,  we  reviewed  our  portfolio  of  patents  and patent
applications.   As  a  result  of  this  review,   various  patents  and  patent
applications  were not renewed.  The  non-renewed  patents  consisted  mostly of
international origin or were not conducive to oral application.

      The main U.S. ME/CFS treatment patent (#6130206) expires October 10, 2017.
Our main patents  covering HIV  treatment  (#4820696,  #5063209,  and  #5091374)
expired or expire on April 11,  2006,  November 5, 2008,  and February 25, 2009,
respectively;  Hepatitis  treatment coverage is conveyed by U.S. patent #5593973
which expires on January 14, 2014. The U.S. Ampligen(R)  Trademark  (#1,515,099)
expires on December 6, 2008 and can be renewed  thereafter  for an additional 10
years. The FDA has granted us "orphan drug status" for our nucleic  acid-derived
therapeutics for ME/CFS,  HIV, and renal cell carcinoma and malignant  melanoma.
Orphan drug status  grants us  protection  against  competition  for a period of
seven years  following FDA approval,  as well as certain federal tax incentives,
and other regulatory benefits.  Patent coverage for the HIV indication following
the  expiration  of patent  #4820696,  #5063209  and  #5091374  is planned to be
obtained from patent pending application #PCT/US 0239890. In the event that this
patent  application  is not  approved,  we still have the  marketing  protection
provided by the orphan drug designation for using Ampligen(R) to treat HIV.

      Based on the results of published,  peer reviewed pre-clinical studies and
clinical trials, we believe that Ampligen(R) may have broad-spectrum  anti-viral
and  anti-cancer  properties.  Approximately  750 patients have  participated in
Ampligen(R)  clinical trials authorized by the FDA at over twenty clinical trial
sites across the U.S., representing the administration of more than 45,000 doses
of this drug.

      We are in the process of preparing an NDA to file with the FDA for the use
of Ampligen(R) in the treatment of patients with ME/CFS. We plan to complete and
file the NDA before year end 2006.

      Alferon N Injection(R)

      Interferons  are a group of  proteins  produced  and  secreted by cells to
combat  diseases.  Researchers  have  identified  four  major  classes  of human
interferon:  alpha,  beta, gamma and omega.  The Alferon N Injection(R)  product
contains a  multi-species  form of alpha  interferon.  The worldwide  market for
injectable  alpha  interferon-based  products has  experienced  rapid growth and
various alpha interferon injectable products are approved for many major medical
uses worldwide.  Alpha interferons are manufactured  commercially in three ways:
by genetic  engineering,  by cell culture, and from human white blood cells. All
three of these types of alpha  interferon  are or were  approved for  commercial
sale in the U.S. Our natural alpha interferon is produced from human white blood
cells.


                                       6


      The  potential  advantages of natural alpha  interferon  over  recombinant
(synthetic)  interferon produced and marketed by other  pharmaceutical firms may
be based upon their respective molecular compositions.  Natural alpha interferon
is  composed  of a family of  proteins  containing  many  molecular  species  of
interferon. In contrast, recombinant alpha interferon each contain only a single
species.  Researchers  have reported that the various species of interferons may
have differing  antiviral  activity  depending  upon the type of virus.  Natural
alpha interferon  presents a broad  complement of species,  which we believe may
account for its higher activity in laboratory studies.  Natural alpha interferon
is  also   glycosylated   (partially   covered  with  sugar   molecules).   Such
glycosylation is not present on the currently U.S.  marketed  recombinant  alpha
interferons.  We  believe  that the  absence of  glycosylation  may be, in part,
responsible  for the production of  interferon-neutralizing  antibodies  seen in
patients   treated   with   recombinant   alpha   interferon.    Although   cell
culture-derived  interferon  is also  composed  of multiple  glycosylated  alpha
interferon  species,  the types  and  relative  quantity  of these  species  are
different from our natural alpha interferon.

      The FDA  approved  Alferon N  Injection(R)  in 1989 for the  intralesional
(within  lesions)  treatment of  refractory  (resistant  to other  treatment) or
recurring  external genital warts in patients 18 years of age or older.  Certain
types  of  human  papillomaviruses  ("HPV")  cause  genital  warts,  a  sexually
transmitted  disease ("STD").  A published  report estimates that  approximately
eight  million new and recurrent  causes of genital warts occur  annually in the
United States alone.

      The U.S.  Alferon(R)  Patents  expire  February  10, 2012  (5,503,828  and
5,676,942) and December 22, 2017 (5,989,441).

      Alferon N Injection(R) [Interferon alfa-n3 (human leukocyte derived)] is a
highly purified,  natural-source,  glycosylated,  multi-species alpha interferon
product. There are essentially no antibodies observed against natural interferon
to date and the product has a relatively low side-effect profile.  Alferon(R) is
the only  natural-source,  multi-species alpha interferon  currently sold in the
U.S.

      The  recombinant  DNA derived  alpha  interferon  are now reported to have
decreased  effectiveness  after one year, probably due to antibody formation and
other severe toxicities.  These detrimental  effects have not been reported with
the use of Alferon N  Injection(R)  which could  allow this  product to assume a
much larger market share.

      It is  our  belief  that  the  use of  Alferon(R)  N in  combination  with
Ampligen(R) has the potential to increase the positive therapeutic  responses in
chronic life threatening  viral diseases.  Combinational  therapy is evolving to
the standard of acceptable  medical care based on a detailed  examination of the
Biochemistry of the body's natural antiviral response.

      Alferon(R) LDO

      Alferon(R) LDO is an  experimental  low-dose,  oral liquid  formulation of
Natural  Alpha  Interferon  and like  Alferon N  Injection(R)  should  not cause
antibody  formation,  which is a problem with recombinant  interferon.  It is an
experimental immunotherapeutic believed to work by stimulating an immune cascade
response in the cells of the mouth and throat,  enabling it to bolster an immune
response  through the entire body  orally.  Oral  interferon  would be much more
economically  feasible for patients and  logistically  manageable in development
programs in third-world  countries  primarily affected by HIV and other emerging
viruses (SARS, Ebola, bird flu, etc.). Oral administration of Alferon(R) N, with
its affordability, low toxicity, no production of antibodies, and broad range of
potential bio activity, could be a breakthrough treatment for viral diseases.


                                       7


      A clinical  study to evaluate  the use of  Alferon(R)  LDO in HIV infected
volunteers was initiated during the second quarter 2005 in Philadelphia, PA. The
study is currently being conducted at Drexel University and Philadelphia  FIGHT,
a  comprehensive  AIDS service  organization  providing  primary care,  consumer
education, advocacy and research on potential treatments and vaccines. The study
is  designed  to  determine   whether   Alferon(R)  LDO  can   resuscitate   the
broad-spectrum  antiviral  and  immunostimulatory  genes.  As of May  30,  2006,
fourteen  patients have enrolled and twelve completed  dosing.  We are currently
receiving  data  from this  study and we are in the  process  of  analyzing  the
results. The trial methodology may have implications for treating other emerging
viruses such as avian influenza (bird flu).

      Oragens

      We  acquired  a series of patents on  Oragens,  potentially  a set of oral
broad  spectrum  antivirals  and  immunological  enhancers,  through a licensing
agreement  with  Temple  University  in  Philadelphia,  PA. We were  granted  an
exclusive  worldwide  license  from  Temple  for  the  Oragens  products.  These
compounds have been evaluated in various  academic  laboratories for application
to chronic viral and immunological disorders.

      The 2', 5'  oligoadenylate  synthetase/RNase  L system is an important and
widely  distributed  pathway for the inhibition of viral  replication  and tumor
growth. The 2', 5' oligoadenylate  synthetase,  up activation by double-stranded
RNA,  synthesizes 2', 5' oligoadenylates  (2-5A) from ATP. These bioactive 2-5As
directly  activate  RNase L, which degrades viral and cellular RNAs resulting in
the inhibition of protein synthesis.

      The  bioactive  2-5A  molecules  can be  degraded  by  various  hydrolytic
enzymes,  resulting in a short half life.  Analogues of these  bioactive  2-5As,
termed  Oragen RNA  compounds,  have been  produced  to increase  stability  and
maintain or increase biological activity without demonstrable toxicity.

      Pursuant to the terms of our  agreement  with Temple,  we are obligated to
pay  royalties  of 2% to 4% of  sales  depending  on  the  amount  of  technical
assistance required. We currently pay a royalty of $30,000 per year to Temple.

RESEARCH AND DEVELOPMENT ("R&D")

      Our focus is on  developing  drugs for use in  treating  viral and  immune
based chronic disorders and diseases  including ME/CFS,  HIV, HPV, SARS and West
Nile Virus. Our current R&D projects target treatment therapies for ME/CFS, HIV,
HPV and other viral diseases.

      Myalgic Encephalomyelitis/Chronic Fatigue Syndrome ("ME/CFS")


                                       8


      Chronic Fatigue Syndrome ("CFS"), also known as Chronic Immune Dysfunction
Syndrome  ("CFIDS")  and,  myalgic  encephalomyelitis  ("ME") is a  serious  and
debilitating   chronic  illness  and  a  major  public  health   problem.   Long
misunderstood,  under-recognized, and under-diagnosed,  ME/CFS is now recognized
by both the government and private sector as a major health  problem,  including
the  National  Institutes  of Health,  U.S.  Centers  for  Disease  Control  and
Prevention ("CDC"),  FDA and Social Security  Administration,  recognizes CFS as
one of the most common chronic illnesses of our time. The CDC listed ME/CFS as a
priority disease, causing severe health and financial problems for the patients,
their  family,  and the  community.  ME/CFS is  endemic in the  population,  but
occasionally  seen in clusters  suggesting  an  infectious  basis.  A variety of
immunological,  endocrine, autonomic nervous system, and metabolic abnormalities
have been documented.  A groundbreaking,  community-based study of ME/CFS by Dr.
Leonard  Jason was  published in the  Archives of Internal  Medicine in 1999 and
showed a prevalence rate of 422 of every 100,000  Americans.  As many as 800,000
people nationwide suffer from CFS, twice the number previously  estimated by the
CDC.  Furthermore,  90% of the patients with the illness are struggling  without
the benefit of medical  diagnosis or treatment.  While ME/CFS  strikes people of
all age, racial,  ethnic, and socioeconomic groups, it is most prevalent amongst
women. Research has shown that ME/CFS is about three times as common in women as
men,  a rate  similar  to that of many  autoimmune  diseases,  such as  multiple
sclerosis  and lupus.  To put this into  perspective,  ME/CFS is over four times
more  common  than HIV  infection  in women,  and the rate of ME/CFS in women is
considerably  higher  than a woman's  lifetime  risk of getting  lung  cancer as
published by the CFIDS Association of America.

      The most common symptom of ME/CFS is  incapacitating  fatigue,  which does
not subside with rest. Many severe ME/CFS patients become completely disabled or
totally  bedridden and are afflicted with severe pain and mental  confusion even
at rest. This  debilitating  tiredness is associated with flu-like symptoms such
as chills,  fever,  headache,  sore throat,  painful lymph nodes,  muscle aches,
weakness and joint pain.  Diagnosis of ME/CFS is a time-consuming  and difficult
process which is generally  arrived at by excluding other illnesses with similar
symptoms  and  comparing  a  patient's   symptoms  with  the  case   definition.
Overlapping symptoms can occur with several diseases, such as fibromyalgia, Gulf
War Illnesses,  and multiple chemical sensitivities.  Many diseases have similar
symptoms  including  Lupus and Lyme disease  which so closely  mimic ME/CFS that
they need to be considered when making a diagnosis to rule them out.

      The case definition for ME/CFS  criteria calls for certain  symptoms to be
present along with fatigue that interferes with physical,  mental,  social,  and
educational activities. Both the fatigue and symptoms must have occurred for (at
least) a six month period.  People with ME/CFS may experience many more than the
symptoms named in the case  definition,  so  knowledgeable  physicians will take
this fact into  consideration  when making a  diagnosis  (after  other  possible
reasons for symptoms have been ruled out).

      The  leading  model of  ME/CFS  pathogenesis  is  thought  to be rooted in
abnormalities in the immune system and brain (central  nervous system),  both of
which  affects  and alters the  function  of the  other.  Because  some cases of
chronic  fatigue  begin with a flu-like  infection,  several  viruses  have been
studied as  possible  causes  because all are  relatively  common in the general
population,   including  Human  Herpesvirus   ("HHV")  6  and  7,  Retroviruses,
Epstein-Barr Virus,  Enteroviruses,  as well as,  Mycoplasmas,  etc. Whilst, the
etiology is likely to be caused by a  collection  of factors,  including  viral,
hormonal,   stress,   and  other  triggers  for  the  illness  in   genetically,
environmentally  or  otherwise  susceptible  individuals  and  continues to be a
subject of discussion.

      Most  ME/CFS  patients  are  treated   symptomatically   with  traditional
treatments  geared toward  treating  symptoms of the disease,  such as improving
quality of sleep,  reducing  pain and  treatment of  depression.  Clinically,  a
number  of  different  therapeutic  approaches  have been  pursued,  but with no
significant clinical success.


                                       9


      In  1998,  we  were  authorized  by  the  FDA  to  initiate  a  Phase  III
multicenter,  placebo-controlled,  randomized,  double blind  clinical  trial to
treat 230  patients  with ME/CFS in the U.S.  The  objective  of this Phase III,
clinical  study,  denoted as Amp 516, was to evaluate the safety and efficacy of
Ampligen(R) as a treatment for ME/CFS.  Over the course of the study, we engaged
the services of 12 clinical investigators at Medical Centers in California,  New
Jersey, Florida, North Carolina, Wisconsin, Pennsylvania, Nevada, Illinois, Utah
and Connecticut.  These clinical investigators were medical doctors with special
knowledge of ME/CFS who have recruited, prescreened and enrolled ME/CFS patients
for  inclusion in the Phase III Amp 516 ME/CFS  clinical  trial.  This  clinical
trial enrolled and randomized over 230 ME/CFS patients. We completed drug dosing
in this trial in August 2004. A preliminary  review of the data collected during
this trial indicated that Ampligen(R) improved exercise treadmill performance by
19.0%  versus  4.2%  in the  placebo  group,  or more  than  twice  the  minimum
considered  medically  significant (6.5%), a statistically  significant increase
(p=0.025).  The major  significance  is the  ability  to safely  obtain  medical
benefits  (increased  physical  performance)  which have largely  eluded others.
Also,   Ampligen(R)   significantly   improved  important   secondary  endpoints
associated  with Quality of Life.  There was no  significant  difference  in the
number of serious  adverse  events,  suggesting that the drug was generally well
tolerated. Given that the FDA has already granted Ampligen(R) Treatment Protocol
Status  and  Orphan  Drug  Status  based on earlier  studies,  we believe  these
medically and statistically significant results, when finalized, will facilitate
FDA review and approval of Ampligen(R) as a therapy to treat ME/CFS.

      Human Immunodeficiency Virus ("HIV")

      Over fifteen  antiviral  drugs are  currently  approved by the FDA for the
treatment  of HIV  infection.  Most target the  specific  HIV  enzymes,  reverse
transcriptase  ("RT") and protease.  The use of various combinations of three or
more of these  drugs is  often  referred  to as  Highly  Active  Anti-Retroviral
Therapy  ("HAART").  HAART involves the  utilization of several  antiretrovirals
with  different  mechanisms  of action to decrease  viral loads in  HIV-infected
patients.  The goal of these  combination  treatments is to reduce the amount of
HIV in the body ("viral load") to as low as possible.  Experience has shown that
using  combinations of drugs from different classes is a more effective strategy
than using only one or two  drugs.  HAART has  provided  dramatic  decreases  in
morbidity and mortality of HIV infection.  Subsequent  experience has provided a
more realistic view of HAART and the  realization  that chronic HIV  suppression
using HAART,  as currently  practiced,  would  require  treatment  for life with
resulting significant cumulative  toxicities.  The various reverse transcriptase
and protease inhibitor drugs that go into HAART have  significantly  reduced the
morbidity and mortality connected with HIV; however there has been a significant
cost due to drug toxicity. It was estimated that 50% of HIV deaths were from the
toxicity of the drugs in HAART.  Some estimates suggest that it would require as
many as 60 years of HAART for elimination of HIV in the infected  patient.  Thus
the  toxicity of HAART drugs and the enormous  cost of treatment  make this goal
impractical.

      We believe that the concept of Strategic Therapeutic  Interruption ("STI")
of HAART provides a unique  opportunity to minimize the current  deficiencies of
HAART  while  retaining  the HIV  suppression  capacities  of HAART.  STI is the
cessation of HAART until HIV again becomes detectable (i.e.,  rebounds) followed
by resumption of HAART with subsequent  suppression of HIV. By re-institution of
HAART,  HIV may be suppressed  before it can inflict damage to the immune system
of the patient.  We believe that Ampligen(R)  combined with the STI approach may
offer a unique  opportunity  to retain  HAART's  superb  ability to suppress HIV
while potentially minimizing its deficiencies.  All present approved drugs block
certain  steps in the life cycles of HIV. None of these drugs address the immune
system,  as  Ampligen(R)  potentially  does,  although  HIV  is an  immune-based
disease.


                                       10


      By using  Ampligen(R) in combination  with STI of HAART, we will undertake
to boost the patients' own immune  system's  response to help them control their
HIV when they are off of HAART. Our minimum  expectation is that Ampligen(R) has
potential to lengthen the HAART-free time interval with a resultant  decrease in
HAART-induced toxicities.  The ultimate potential, which of course requires full
clinical  testing to accept or reject the  hypothesis,  is that  Ampligen(R) may
potentiate  STI of HAART to the point that the cell mediated  immune system will
be sufficient to eliminate  requirement for HAART. Clinical results of using our
technology has been presented at several International AIDS Scientific Forums.

      Our  Amp  720  HIV  study  is a  treatment  using  a  Strategic  Treatment
Interruption ("STI"). The patients' antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as  mono-immunotherapy.  Patients, who have completed
at least nine months of Ampligen(R)  therapy,  were able to stay off HAART for a
total STI  duration  with a mean time of 29.0 weeks  whereas the control  group,
which was also taken off  HAART,  but not given  Ampligen(R),  had  earlier  HIV
rebound  with a mean  duration of 18.7  weeks.  Thus,  on  average,  Ampligen(R)
therapy  spared the  patients  excessive  exposure to HAART,  with its  inherent
toxicities, for more than 11 weeks.

      Forty one HIV patients have  participated in this 64 week study.  The rate
of enrollment  depends on patient  availability  and on other  products being in
clinical  trials for the  treatment  of HIV,  causing  competition  for the same
patient  population.  At  present,  more  than  18 FDA  approved  drugs  for HIV
treatment may compete for available  patients.  The length, and subsequently the
expense of these studies,  will also be determined by an analysis of the interim
data,  which  will  determine  when  completion  of  the  ongoing  Phase  IIb is
appropriate  and whether a Phase III trial will be  conducted  or not. In case a
Phase  III  study is  required;  the FDA  might  require  a  patient  population
exceeding  the current one which will  influence the cost and time of the trial.
Accordingly,  the number of  "unknowns"  is  sufficiently  great to be unable to
predict  when,  or  whether,  we may  obtain  revenues  from  our HIV  treatment
indications.

      Human Papilloma Virus (HPV)

      Human papilloma virus ("HPV") is one of the most common causes of sexually
transmitted  infection in the world.  Experts estimate that there are more cases
of genital HPV infection than of any other sexually  transmitted disease ("STD")
in the United States.  Overall,  in the United  States,  an estimated 20 million
people (15% of the population) are currently  infected with HPV, 50-75% of which
is with high-risk  types,  and about 5.5 million people are infected every year.
It has been estimated that a least 50% of sexually  active men and women acquire
genital HPV infection at some point in their lives.

      Treating genital warts does not cure a HPV infection. The virus remains in
the body in an  inactive  state after warts are  removed.  A person  treated for
genital warts may still be able to transmit the  infection.  Common  methods for
removing genital warts involve surgically removing them. Cryotherapy is a method
that  entails  freezing  off the wart with  liquid  nitrogen  and is  relatively
inexpensive,  safe and effective. The downside to this procedure beyond the pain
factor is it must be performed by a trained health care provider.  Laser therapy
(using an intense light to destroy the warts) or surgery (cutting off the warts)
has the  advantage of getting rid of warts in a single  office  visit.  However,
treatment  can be  expensive  and the  operator  must be  well-trained  in these
methods. In addition, surgery will most likely cause scarring over the afflicted
area.


                                       11


      There are additionally a number of topical creams and solutions  available
to treat  genital  warts.  Bloodroot  paste  is made  from  naturally  occurring
substances,  but its  effects on  treating  genital  warts are not  conclusively
supportive.  Condylox (also called  podophyllin) is a brown liquid that causes a
burning  sensation  as it  dries,  but it  must  be  washed  off by 4 to 6 hours
otherwise it may be dangerous. Condylox can be quite expensive as well. Condysil
is an  additional  cream  that may be  applied.  It  consists  of "all  natural"
ingredients and its producers claim it produces no scarring. The current leading
treatment of genital warts is the topical cream Aldara, but in fact there may be
a reoccurrence  rate of up to 40% when this drug is used.  Treatment for genital
warts may also come in the form of injections. Intron A is a substance that must
be injected 3 times weekly and  Alferon(R) N, which is the only natural  source,
multi-species  alpha interferon  currently sold in the US for HPV treatment,  is
injected twice weekly.

      Hepatitis C Virus ("HCV")

      Hepatitis C infection is typically mild in its early stages,  and is often
not  diagnosed  until a late state when it has caused  severe liver  disease.  A
typical cycle of disease from infection to symptomatic liver disease can take 20
years; therefore, the true impact of HCV may not be fully apparent.  Hepatitis C
is believed to be transmitted  only by blood.  However,  unlike many other blood
borne viruses (like HCV),  virtually  any source of blood  products  seems to be
capable of carrying the virus, even if the source is indirect like a used razor,
for example. This makes Hepatitis C far more transmittable than most other blood
borne viruses including HIV.

      Hepatitis  C is an RNA virus.  Once an  infection  has begun,  Hepatitis C
creates different genetic  variations of itself within the body of the host. The
mutated  forms are  frequently  different  enough from their  ancestor  that the
immune system cannot  recognize them.  Thus, even if the immune system begins to
succeed  against one variation,  the mutant strains quickly take over and become
new,  predominant  strains.  Thus, the development of antibodies against HCV may
not  produce  an  immunity  against  the  disease  like it does with most  other
viruses.  More than 80% of  individuals  infected  with HCV will  progress  to a
chronic form of the disease.

      The World Health Organization  estimates that more than 4.5 million people
in the United  States are  infected  with  Hepatitis C and more than 200 million
worldwide.  A vaccine  against  Hepatitis C is not  available and there are many
times more people infected with HCV than HIV (the virus that causes AIDS). It is
anticipated that without prompt intervention to treat infected populations,  the
death rate from Hepatitis C could surpass that from AIDS.

      Alferon N  Injection(R)  has been studied for the  potential  treatment of
HIV, Hepatitis C and other  indications.  ISI, the company from which Hemispherx
obtained  rights to Alferon N Injection(R),  has conducted  clinical trials with
regard  to the  use of  Alferon  N  Injection(R)  in the  treatment  of HIV  and
Hepatitis C. While ISI found the results to be  encouraging,  in both  instances
the FDA determined that additional trials were necessary.


                                       12


      We are evaluating  the  possibility of conducting a pivotal trial for HCV.
This trial would be designed to evaluate  the  efficacy  and safety of Alferon N
Injection(R)  in  comparison  with an  untreated  control  group  in  previously
untreated  patients  with  chronic  HCV.  The  primary  endpoint  would  be  the
proportion of patients in whom ALT is normal at the end of 40 weeks of treatment
and at the end of the 24 week  follow-up  period.  We  would  plan on  enrolling
approximately 208 patients.  We will be making a decision on this clinical trial
by June 2006.

      Other Diseases

      A  clinical  study  has been  approved  by the  Clinical  Research  Ethics
Committee of the Kowloon West Cluster at the Princess  Margaret Hospital in Hong
Kong to evaluate the use of Alferon(R)  LDO (Low Dose Oral  Interferon  Alfa-N3,
Human Leukocyte Derived) in normal volunteers and/or asymptomatic  subjects with
exposure to a person known to have Severe Acute Respiratory  Syndrome  ("SARS").
This study  completed the dosing of ten patients  during the fourth quarter 2005
and we expect to  complete  analyzing  the  results  of this study in the coming
months.

      SARS is one of a group of  "emerging"  infectious  disease  that  recently
attracted the intense scrutiny of public health officials due to the severity of
disease in epidemics based in Asia, but also involving  Europe and North America
as well.  An  international  effort  to limit its  spread  and to  identify  the
infectious agent has been spectacularly  successful and of major significance in
the  prevention  of a  pandemic.  A  replicating  virus of  classic  coronavirus
morphology was identified initially by electron microscopy.  This identification
of the virus family allowed the rapid  identification of a new human coronavirus
(SARS-CoV) as the etiological agent of SARS.  Recently it has been observed that
the US FDA approved  antiviral drug,  Alferon(R)  (i.e.-natural  interferon) has
significant  activity  against  SARS-CoV in vitro as  indicated  by reduction in
cytopathic  effect  ("CPE").  This  protocol  was  designed  to  respond  to any
reemergence  of SARS with a prophylaxis  trial at epidemic sites to be conducted
to  evaluate  the  activity  of  Alferon(R)  LDO  (low  dose  oral)  to  prevent
symptomatic  infection by  SARS-CoV.  Gene  microarray  analysis of infection by
SARS-CoV and the effect of Alferon(R)  LDO are used in the design and conduct of
this clinical trial.  Differential  cellular gene responses to infection and the
response to Alferon(R) may predict clinical outcomes.

      This trial  methodology may have  implications for treating other emerging
viruses such as avian influenza. Present production methods for vaccines involve
the use of millions of chicken  eggs and would be slow to respond to an outbreak
according to a convened World Health Organization expert panel in November 2004.
Health officials are also concerned that bird flu could mutate to cause the next
pandemic and render present  vaccines  under  development  ineffective.  We have
prepared  more than 300,000  doses of Alferon(R)  LDO for  appropriate  clinical
programs.

      With the threat of an avian influenza pandemic rising and health officials
warning that the virus could develop  resistance to current flu treatments,  the
pursuit of a cost-effective and complementary  treatment to existing  antivirals
and vaccines has become  critical.  This combination may permit the use of lower
dosages and fewer injections of the antivirals and vaccines used to combat avian
flu,  thereby  decreasing the cost of both  immunization  programs and treatment
programs for the full-blown disease.


                                       13


      In  antimicrobial  (antibacterial)  therapy,  which  is  the  best-studied
clinical  model,   synergistic   drug   combinations   may  result  in  curative
conditions/outcomes,  often not observed  when the single drugs are given alone.
In the case of avian influenza where global drug supplies are  presumptively  in
very  limited  supply  relative  to  potential  needs,  therapeutic  synergistic
combinations  could not only affect the disease outcome,  but also the number of
individuals able to access therapies.

      In  a  recently  reported  study  from  a  vaccine  group  in  Japan,  the
incorporation of poly I: poly C (dsRNA) into a nasal  administration of a killed
influenza A preparation  converted a poorly  immunogenic  response into a highly
efficacious  vaccine in  protection  of mice from  lethal  infection  from human
influenza A. Ampligen(R) is a dsRNA which currently is undergoing testing in the
animal model.

      A  preclinical   study  was  initiated  in  June  2005,  to  determine  if
Ampligen(R)  enhances the  effectiveness of different drug combinations on avian
influenza. The preclinical study suggests a new, and potentially pivotal role of
double-stranded  RNA  ("dsRNA")  therapeutics  in improving  the efficacy of the
present  standards in care in both  influenza  prevention and treatment of acute
disease.  The preclinical study is being conducted by research affiliates of the
National  Institutes  of Health at Utah State  University  to examine  potential
therapeutic synergies with different drug combinations.  The ongoing research is
comparing the relative protection conveyed by Tamiflu  (oseltamivir,  Roche) and
Relenza  (Zanamivir,  GlaxoSmithKline)  with Ampligen(R)  (dsRNA),  alone and in
combination,  against the avian flu virus (H5N1).  Cell destruction was measured
in vitro using  different  drug  combinations.  Both drugs,  given  alone,  were
effective  in  inhibiting  cell  destruction  by  avian  influenza,   but  viral
suppression with the combination was greater than either drug alone. The overall
assessment is that there was improvement in cell protection when Ampligen(R) was
combined with oseltamivir carboxylate (Tamiflu) and Zanamivir (Relenza). Further
immediate experimental tests are planned.

      Recently,  Japanese researchers (Journal of Virology page 2910, 2005) have
found that dsRNAs increase the  effectiveness of influenza  vaccine by more than
300% and may also convey  "cross-protection  ability  against  variant  viruses"
(mutated  strains of influenza  virus).  In October  2005,  we signed a research
agreement with the National Institute of Infectious  Diseases,  in Tokyo, Japan.
The collaboration,  by Hideki Hasegawa,  M.D., Ph.D., Chief of the Laboratory of
Infectious   Disease  Pathology,   will  assess  our  experimental   therapeutic
Ampligen(R) as a co-administered  immunotherapeutic  to the Institution's  nasal
flu vaccine.

      In October  2005,  we also  engaged the Sage Group,  Inc.,  a health care,
technology  oriented,  strategy and  transaction  advisory firm, to assist us in
obtaining a strategic  alliance in Japan for the use of  Ampligen(R) in treating
Chronic  Fatigue  Syndrome  or CFS.  In the past year  leaders  in the  Japanese
medical  community have  established the Japanese Society of the Fatigue Science
and the Osaka City University Hospital opened the Fatigue Clinical Center as the
initial step in their Fatigue Research Project.

      In November  2005,  we entered into an agreement  with Defence R&D Canada,
Suffield  ("DRDC  Suffield"),  an agency of the Canadian  Department of National
Defence,  to evaluate the  antiviral  efficacy of our  experimental  therapeutic
Ampligen(R) and Alferon(R) for protection  against human  respiratory  influenza
virus  infection in well validated  animal  models.  DRDC Suffield is conducting
research and development of new drugs that could potentially  become part of the
arsenal of existing  antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the  respiratory  influenza
virus infection on a mouse-adapted strain of human influenza.  DRDC Suffield has
already conducted  extensive research in the use of liposome delivery technology
to enhance the antiviral activity of a closely-allied Ampligen(R) analogue, Poly
ICLC (an immunomodulating  dsRNA) which is very similar to Ampligen(R).  Results
suggest that ribo nucleic acid-based drugs have the ability to elicit protective
broad-spectrum  antiviral  immunity against various pathogenic  viruses.  Hence,
there is the potential for efficacy to be maintained against mutating strains of
an influenza virus.  Liposomes,  a carrier system for nucleic  acid-based drugs,
have  shown an  ability  to protect  these  drugs  against in vivo  degradation,
delivering  them to  intracellular  sites of  infection,  thereby  reducing  any
toxicity and  prolonging  their  therapeutic  effectiveness.  Protection  can be
afforded for 21 days with two doses of dsRNA. It is believed that in humans with
active flu infection, Tamiflu, given twice daily, may ameliorate symptoms.


                                       14


      A clinical  study to evaluate  the use of  Alferon(R)  LDO in HIV infected
volunteers was initiated during the second quarter 2005 in Philadelphia, PA. The
study  is  currently  being  conducted  at  two  sites,  Drexel  University  and
Philadelphia FIGHT, a comprehensive AIDS service organization  providing primary
care,  consumer  education,  advocacy and research on potential  treatments  and
vaccines.  The  study  is  designed  to  determine  whether  Alferon(R)  LDO can
resuscitate  the  broad-spectrum  antiviral  and  immunostimulatory  genes.  The
initial  patient  enrolled in this study in July 2005 and, as of December  2005,
seven patients have enrolled and completed  dosing.  We are currently  receiving
data from this study and we are in the process of  analyzing  the  results.  The
trial methodology may have implications for treating other emerging viruses such
as avian influenza (bird flu).  Present  production methods for vaccines involve
the use of millions of chicken  eggs and would be slow to respond to an outbreak
according  to a recently  convened  WHO expert  panel in November  2004.  Health
officials  are also  concerned  that  bird flu  could  mutate  to cause the next
pandemic and render present vaccines under development ineffective.

      In  September  2004,  we  commenced  a  clinical  trial  using  Alferon  N
Injection(R) to treat patients infected with the West Nile Virus. The infectious
Disease  section of New York Queens  Hospital and the Weill  Medical  College of
Cornell University are conducting this double-blinded, placebo controlled trial.
This study plans to enroll 60 patients as they become  available.  As of May 30,
2006, nine patients have entered this study. The CDC reports that 2,819 cases of
West Nile Virus have been  reported in the US as of January 10, 2006,  including
105 deaths.

      In 2005 we  completed  the  transfer and  consolidation  of our  Rockville
Quality Assurance Lab and equipment into our New Brunswick facility.  We believe
this newly  consolidated lab will provide more  efficiencies  with regard to the
quality assurance needs for both Ampligen(R) and Alferon N Injection(R).

      An FDA authorized  Phase I/II study of  Ampligen(R)  in cancer,  including
patients with renal cell  carcinoma  was completed in 1994.  The results of this
study  indicated  that patients  receiving high doses  (200-500mg)  twice weekly
experienced an increase in medium survival compared to the low dose group and as
compared to an historical control group. We received  authorization from the FDA
to initiate a Phase II study using Ampligen(R) to treat patients with metastatic
renal cell  carcinoma.  Patients with  metastatic  melanoma were included in the
Phase I/II study of Ampligen(R) in cancer.  The FDA has authorized us to conduct
a Phase II clinical  trial using  Ampligen(R)  in melanoma.  We do not expect to
devote any significant resources to funding these studies in the near future.


                                       15


MANUFACTURING

      Historically,  we have  outsourced  the  manufacturing  of  Ampligen(R) to
certain  contractor  facilities  in the  United  States and South  Africa  while
maintaining  full quality control and  supervision of the process.  Nucleic Acid
polymers  constitute the raw material used in the production of Ampligen(R).  We
previously acquired our raw materials from Ribotech,  Ltd.  ("Ribotech") located
in South  Africa.  Ribotech,  is  jointly  owned  by us  (24.9%)  and  Bioclones
(Proprietary),  Ltd. (75.1%). Bioclones manages and operates Ribotech. There are
a limited number of  manufacturers in the United States available to provide the
polymers.  At present,  we do not have any agreements with third parties for the
supply of any of such materials. In order to obtain Ampligen(R) raw materials of
higher quality (GMP  certified) and on a more regular  production  basis, we are
setting up polymer manufacturing  operations in our New Brunswick facility. This
consolidation  and transfer of manufacturing  operations has been implemented in
response to a recent  inspection of the Ribotech  facility in South Africa,  our
previous  supplier of polymers.  This facility is not, at present,  suitable for
the commercial  manufacture of polymers used to make  Ampligen(R).  We have also
identified  and  contacted two  manufacturers  for the possible  manufacture  of
polymers.  Engagement of either of these facilities would provide back up to our
NJ  facility  and  additional  production  capacity.  This  transfer  of polymer
manufacturing to our own facilities, and/or to another contract manufacturer may
delay certain steps in commercialization process, specifically, our NDA filing.

      Until  1999,  we  distributed  Ampligen(R)  in the form of a  freeze-dried
powder to be  formulated  by  pharmacists  at the site of use.  We  perfected  a
production  process to produce ready to use liquid Ampligen(R) in a dosage form,
which  will  mainly be used upon  commercial  approval  of  Ampligen(R).  We had
engaged  the   services  of   Schering-Plough   ("Schering")   to  mass  produce
ready-to-use  Ampligen(R)  doses;  however,  in connection with settling various
manufacturing  infractions  previously noted by the FDA, Schering entered into a
"Consent  Decree"  with the FDA  whereby,  among  other  things,  it  agreed  to
discontinue various contract (third party)  manufacturing  activities at various
facilities  including its San Juan, Puerto Rico, plant.  Ampligen(R)  (which was
not involved in any of the cited  infractions)  was produced at this Puerto Rico
plant from year 2000-2004. Operating under instructions from the Consent Decree,
Schering  advised  us that it would no longer  manufacture  Ampligen(R)  in this
facility  beyond  2004  and  would  assist  us in an  orderly  transfer  of said
activities to other non Schering facilities.

      On December 9, 2005, we executed a Supply  Agreement with  Hollister-Stier
Laboratories LLC of Spokane,  Washington  ("Hollister-Stier"),  for the contract
manufacturing of Ampligen(R) for a five year term.  Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier  will formulate and bottle
the  Ampligen(R).  In November  2005,  we paid $100,000 as a deposit in order to
initiate the  manufacturing  project.  This deposit was expensed as research and
development  during  the  4th  Quarter  2005.  The  achievement  of the  initial
objectives  described  in  the  agreement,   in  combination  with  our  polymer
production facility under construction in New Brunswick,  N.J., may enable us to
manufacture the raw materials for approximately  10,000 doses of Ampligen(R) per
week. We executed a confidentiality  agreement with Hollister-Stier;  therefore,
we commenced the transfer of our  manufacturing  technology to  Hollister-Stier.
Currently,  Hollister-Stier  has  completed  two  pilot  manufacturing  runs  of
Ampligen(R) for stability testing.


                                       16


      We have  identified  two other cGMP  production  facilities  in the United
States  capable  of  manufacturing  Ampligen(R).  Engagement  of either of these
facilities would provide back-up to  Hollister-Stier  and/or provide  additional
production  capacity if needed. We are reviewing proposals from these production
facilities and expect to act upon one or the other at the appropriate time.

      The purified drug  concentrate  utilized in the  formulation  of Alferon N
Injection(R)  is  manufactured  in our New  Brunswick,  New Jersey  facility and
Alferon N  Injection(R)  was  formulated  and packaged at a production  facility
formerly  owned and operated by Abbott  Laboratories  located in Kansas.  Abbott
Laboratories has sold the facility to Hospira.  Hospira  recently  completed the
production  of 11,590  vials.  Hospira is ceasing the labeling and  packaging of
Alferon N  Injection(R)  as they are  seeking  larger  production  runs for cost
efficiency  purposes.  We have identified two manufacturers  and, on February 8,
2006, we executed a  Manufacturing  and Safety  Agreement  with  Hyaluron,  Inc.
("Hyaluron") of Burlington,  Massachusetts,  for the formulation,  packaging and
labeling of Alferon N  Injection(R).  Pursuant to the Agreement,  we will supply
raw materials in sufficient  quantity and provide any pertinent  information  to
the project.

      We have begun  preliminary  work to convert the third lot of approximately
13,000 vials to finished goods inventory with an anticipated completion date for
the third quarter  2006. By the first quarter 2007, we anticipate  manufacturing
new  Alferon  N  Injection(R)  lots  from  blood  leukocytes  at our New  Jersey
facility.  Final  formulation  and packaging would be completed by a third party
contractor as noted above.

      The transfer of Ampligen(R) raw materials production to our own facilities
has obvious  advantages  with  respect to overall  control of the  manufacturing
procedure of  Ampligen(R)'s  raw materials,  keeping costs down and  controlling
regulatory  compliance  issues  (other parts of the of our 43,000 sq. ft. wholly
owned FDA approved facility are already in compliance for Alferon N Injection(R)
manufacture).  This will also allow us to obtain  Ampligen(R) raw materials on a
more consistent  manufacturing  basis. As of April 30, 2006, we have capitalized
approximately  $1,400,000  towards the  construction  and  installation  of this
production line at our New Jersey  facility.  The installation of a raw material
production  line has been completed and is now in production  with the first lot
of  Ampligen(R)  raw material  being  produced in the second  quarter  2006.  We
estimate  the  total  cost  of  establishing  this  production  line  to be some
$1,900,000,  including modifications to our New Brunswick facility. This polymer
production line will have the capacity to produce up to four kilograms per week,
or 100  kilograms per year which should allow us to  manufacture  up to one-half
million  400  mg  doses  per  year.  We  have  also  identified  three  contract
manufacturers  to  expand  polymer  manufacture,   if  necessary,  and  obtained
preliminary proposals from two and initiated discussions with the third.

MARKETING/DISTRIBUTION

      Our marketing strategy for Ampligen(R)  reflects the differing health care
systems around the world, and the different  marketing and distribution  systems
that are used to supply  pharmaceutical  products to those systems. In the U.S.,
we expect that, subject to receipt of regulatory  approval,  Ampligen(R) will be
utilized in four medical arenas: physicians' offices, clinics, hospitals and the
home treatment setting.  We currently plan to use a service provided in the home
infusion  (non-hospital)  segment of the U.S. market to execute direct marketing
activities,  conduct physical distribution of the product and handle billing and
collections.  Accordingly,  we are developing  marketing plans to facilitate the
product  distribution  and medical support for indication,  if and when they are
approved,  in each arena.  We believe that this  approach  will  facilitate  the
generation of revenue without  incurring the substantial costs associated with a
sales force.  Furthermore,  management believes that the approach will enable us
to retain many options for future marketing strategies. In February 1998, we and
Accredo  Health  Services  (formerly  Gentiva  Health  Services)  entered into a
Distribution/Specialty  Agreement for the  distribution  of Ampligen(R)  for the
treatment of ME/CFS patients under the U.S. treatment protocols.


                                       17


      In Europe, we plan to adopt a country-by-country and, in certain cases, an
indication-by-indication  marketing strategy due to the heterogeneity regulation
and  alternative  distribution  systems in these areas. We also plan to adopt an
indication-by-indication  strategy  in Japan.  Subject to receipt of  regulatory
approval, we plan to seek strategic partnering  arrangements with pharmaceutical
companies to facilitate introductions in these areas. The relative prevalence of
people  from  target  indications  for  Ampligen(R)   varies   significantly  by
geographic  region,  and we intend to adjust our clinical and marketing planning
to reflect  the  specialty  of each area.  In October  1994,  we entered  into a
licensing  agreement  with  Bioclones  (Propriety)  Limited  ("Bioclones")  with
respect to co-development  of various RNA drugs,  including  Ampligen(R),  for a
period ending three years from the expiration of the last licensed patents.  The
licensing agreement provided  SAB/Bioclones with an exclusive  manufacturing and
marketing license for certain southern hemisphere  countries  (including certain
countries in South  America,  Africa and Australia as well as the United Kingdom
and Ireland (the licensed territory). In 2004, we initiated a lawsuit in Federal
Court  identifying a  conspiratorial  group seeking to illegally  manipulate our
stock for  purposes of bringing  about a hostile  takeover of  Hemispherx.  This
conspiratorial group includes Bioclones.  In Spain, Portugal and Andorra we have
entered into a Sales Distribution Agreement with Laboratorios del Dr. Esteve, S.
A., a major pharmaceutical firm headquartered in Spain.

      We continue  our efforts to  establish  an  internal  marketing  and sales
infrastructure  to  support  the sales of Alferon N  Injection(R)  in the United
States.  We  continually  search for qualified  sales managers to increase sales
coverage  in all major US  markets.  Our  current  sales  force  includes  three
regional  sales  managers in Texas,  Florida and New York.  Our sales force will
introduce Alferon N Injection(R) and promote Alferon N Injection(R) to OB GYN's,
dermatologists,  and infectious disease physicians and particularly STD Clinics,
who are  involved in the  treatment  of patients  with  refractory  or recurring
external  genital warts, as well as physicians about the growing problem and the
risks of HPV.  We also  intend  to expand  our  marketing/sales  programs  on an
international  basis with our  primary  focus on Europe.  This  program is being
designed to engage European pharmaceutical distributors to market and distribute
Alferon N Injection(R).

COMPETITION

      Our potential competitors are among the largest  pharmaceutical  companies
in the world, are well known to the public and the medical  community,  and have
substantially   greater   financial   resources,    product   development,   and
manufacturing and marketing capabilities than we have.

      These  companies and their  competing  products may be more  effective and
less costly than our products. In addition,  conventional drug therapy,  surgery
and other more  familiar  treatments  will offer  competition  to our  products.
Furthermore, our competitors have significantly greater experience than we do in
pre-clinical testing and human clinical trials of pharmaceutical products and in
obtaining  FDA,  EMEA Health  Protection  Branch  ("HPB")  and other  regulatory
approvals of products.  Accordingly,  our  competitors  may succeed in obtaining
FDA, EMEA and HPB product approvals more rapidly than us. If any of our products
receive regulatory  approvals and we commence  commercial sales of our products,
we will also be competing with respect to manufacturing efficiency and marketing
capabilities,  areas in which we have no experience. Our competitors may possess
or obtain patent protection or other intellectual  property rights that prevent,
limit or  otherwise  adversely  affect our  ability  to  develop or exploit  our
products.


                                       18


      The major  competitors  with drugs to treat HIV  diseases  include  Gilead
Pharmaceutical,  Pfizer, Bristol-Myers, Abbott Labs, Glaxo Smithkline, Merck and
Schering-Plough  Corp. Alferon N Injection(R)  currently competes with a product
produced by Schering for treating  genital  warts.  3M  Pharmaceutical  also has
received FDA approval for its immune response modifier product,  Aldera, for the
treatment of genital and perianal  warts.  We believe the approval and marketing
of this product is the main reason that sales of Alferon N Injection(R) have not
met our expectations in the current year.

GOVERNMENT REGULATION

      Regulation by governmental  authorities in the U.S. and foreign  countries
is and will be a significant  factor in the manufacture and marketing of Alferon
N  products  and  our  ongoing  research  and  product  development  activities.
Ampligen(R)  and the products  developed  from the ongoing  research and product
development   activities   will   require   regulatory   clearances   prior   to
commercialization. In particular, new human drug products for humans are subject
to rigorous preclinical and clinical testing as a condition for clearance by the
FDA and by similar  authorities  in foreign  countries.  The lengthy  process of
seeking these  approvals,  and the ongoing process of compliance with applicable
statutes  and  regulations,  has  required,  and will  continue  to require  the
expenditure of substantial resources.  Any failure by us or our collaborators or
licensees  to obtain,  or any delay in  obtaining,  regulatory  approvals  could
materially  adversely  affect the marketing of any products  developed by us and
our ability to receive product or royalty revenue.  We have received orphan drug
designation  for certain  therapeutic  indications,  which might,  under certain
conditions,  accelerate  the  process  of  drug  commercialization.   Alferon  N
Injection(R) is only approved for use in intra-lesional  treatment of refractory
or recurring external genital warts in patients 18 years of age or older. Use of
Alferon N Injection(R) for other applications requires regulatory approval.

      A  "Fast-Track"  designation  by the FDA, while not affecting any clinical
development  time per se, has the  potential  effect of reducing the  regulatory
review  time by  fifty  percent  (50%)  from  the time  that a  commercial  drug
application  is  actually  submitted  for final  regulatory  review.  Regulatory
agencies  may  apply a "Fast  Track"  designation  to a  potential  new  drug to
accelerate the approval and commercialization process. Criteria for "Fast Track"
include:  a) a devastating disease without adequate therapy and b) laboratory or
clinical evidence that the candidate drug may address the unmet medical need. As
of this date,  we have not  received  a  Fast-Track  designation  for any of our
potential  therapeutic  indications  although  we  have  received  "Orphan  Drug
Designation"  for both  ME/CFS and  HIV/AIDS  in the U.S.  We will  continue  to
present data from time to time in support of obtaining  accelerated  review.  We
have not yet  submitted  any NDA for  Ampligen(R)  or any other  drug to a North
American  regulatory  authority.  In 2000,  we submitted an emergency  treatment
protocol for clinically-resistant HIV patients, which was withdrawn by us during
the  statutory 30 day  regulatory  review period in favor of a set of individual
physician-generated applications. There are no assurances that authorizations to
commence such treatments will be granted by any regulatory authority or that the
resultant treatments, if any, will support drug efficacy and safety. In 2001, we
did receive FDA authorization for two separate Phase IIb HIV treatment protocols
in which our drug is combined with certain  presently  available  antiretroviral
agents. Interim results were presented in 2002 and 2003 at various international
scientific meetings.


                                       19


      We are subject to various federal,  state and local laws,  regulations and
recommendations relating to such matters as safe working conditions,  laboratory
and manufacturing  practices, the experimental use of animals and the use of and
disposal of hazardous or potentially hazardous substances, including radioactive
compounds and infectious  disease  agents,  used in connection with our research
work. The laboratory and production facility in New Brunswick, New Jersey, which
we acquired from ISI, is approved for the  manufacture of Alferon N Injection(R)
and we believe it is in substantial  compliance  with all material  regulations.
However,  we cannot give assurances that facilities  owned and operated by third
parties that are utilized in the manufacture of our products, are in substantial
compliance, or if presently in substantial compliance, will remain so.

RESEARCH AND DEVELOPMENT/COLLABORATIVE AGREEMENTS

      In  1994,   we  entered  into  a  licensing   agreement   with   Bioclones
(Proprietary)  limited  ("Bioclones") for manufacturing and international market
development in Africa,  Australia,  New Zealand,  Tasmania,  the United Kingdom,
Ireland and certain countries in South Africa, of Ampligen(R) and Oragen(TM). On
December  27,  2004,  we  initiated  a lawsuit in Federal  Court  identifying  a
conspiratorial  group seeking to illegally  manipulate our stock for purposes of
bringing  about a hostile  takeover of  Hemispherx.  This  conspiratorial  group
includes Bioclones.

      In 1998,  we entered  into a strategic  alliance  with  Accredo to develop
certain  marketing and  distribution  capacities  for  Ampligen(R) in the United
States.  Accredo is one of the nation's  largest home health care companies with
over 400  offices  and sixty  thousand  caregivers  nationwide.  Pursuant to the
agreement,   Accredo  assumed  certain   responsibilities  for  distribution  of
Ampligen(R)  for which they  received a fee.  Through this  arrangement,  we may
mitigate the necessity of incurring  certain  up-front  costs.  Accredo has also
worked with us in  connection  with the Amp 511 ME/CFS cost  recovery  treatment
program,  Amp 516 ME/CFS  Phase III  clinical  trial and the Amp 719  (combining
Ampligen(R)  with other antiviral  drugs in HIV-salvage  therapy and Amp 720 HIV
Phase IIb clinical  trials now under way).  There can be no assurances that this
alliance will develop a significant  commercial  position in any of its targeted
chronic  disease  markets.  The  agreement  had an  initial  one year  term from
February 9, 1998 with  successive  additional one year terms unless either party
notifies the other not less than 180 days prior to the  anniversary  date of its
intent to terminate the  agreement.  Also,  the agreement may be terminated  for
uncured  defaults,  or  bankruptcy,  or  insolvency  of  either  party  and will
automatically  terminate upon our receiving an NDA for Ampligen(R) from the FDA,
at which  time,  a new  agreement  will need to be  negotiated  with  Accredo or
another major drug distributor.

      We  acquired  a series of patents on  Oragens,  potentially  a set of oral
broad  spectrum  antivirals  and  immunological  enhancers,  through a licensing
agreement  with  Temple  University  in  Philadelphia,  PA. We were  granted  an
exclusive  worldwide  license  from  Temple  for  the  Oragens  products.  These
compounds have been evaluated in various  academic  laboratories for application
to  chronic  viral  and  immunological  disorders.  The  2',  5'  oligoadenylate
synthetase/RNase L system is an important and widely distributed pathway for the
inhibition  of viral  replication  and tumor growth.  The 2', 5'  oligoadenylate
synthetase,   up  activation  by   double-stranded   RNA,   synthesizes  2',  5'
oligoadenylates  (2-5A) from ATP. These bioactive 2-5As directly  activate RNase
L, which degrades viral and cellular RNAs resulting in the inhibition of protein
synthesis.  The bioactive 2-5A  molecules can be degraded by various  hydrolytic
enzymes,  resulting in a short half life.  Analogues of these  bioactive  2-5As,
termed  Oragen RNA  compounds,  have been  produced  to increase  stability  and
maintain or increase biological activity without demonstrable toxicity. Pursuant
to the terms of our agreement with Temple,  we are obligated to pay royalties of
2% to 4% of sales depending on the amount of technical assistance  required.  We
currently  pay a royalty of $30,000  per year to Temple.  This  agreement  is to
remain in effect until the date that the last  licensed  patent  expires  unless
terminated  sooner by mutual consent or default due to royalties not being paid.
The last Oragen(TM) patent expires on June 1, 2018. We record the payment of the
royalty as research and development cost for the period incurred.


                                       20


      In December  1999, we entered into an agreement  with Biovail  Corporation
International   ("Biovail").   Biovail   is  an   international   full   service
pharmaceutical   company   engaged  in  the   formulation,   clinical   testing,
registration and manufacture of drug products  utilizing  advanced drug delivery
systems.  Biovail is  headquartered  in Toronto,  Canada.  The agreement  grants
Biovail the exclusive distributorship of our product in the Canadian territories
subject to certain terms and  conditions.  In return,  Biovail agrees to conduct
certain   pre-marketing   clinical  studies  and  market  development  programs,
including without limitation, expansion of the Emergency Drug Release Program in
Canada with respect to our products. In addition, Biovail agrees to work with us
in  preparing  and  filing  a  New  Drug  Submission  with  Canadian  Regulatory
Authorities at the appropriate time.  Biovail invested  $2,250,000 in Hemispherx
equity  at prices  above the then  current  market  price and  agreed to make an
additional  investment  of  $1,750,000  based on  receiving  approval  to market
Ampligen(R) in Canada from the appropriate regulatory authorities in Canada. The
agreement  requires  Biovail to buy  exclusively  from us and penetrate  certain
market segments at specific rates in order to maintain market  exclusivity.  The
agreement  terminates  on December  15,  2009,  subject to  successive  two-year
extensions by the parties and subject to earlier  termination by the parties for
uncured defaults under the agreement,  bankruptcy or insolvency of either party,
or  withdrawal  of our product from Canada for a period of more than ninety days
for serious adverse health or safety reasons.

      In  May  2000,  we  acquired  an  interest  in  Chronix  Biomedical  Corp.
("CHRONIX").  Chronix  focuses upon the  development of diagnostics  for chronic
diseases.  We issued  100,000  shares of common stock to Chronix  toward a total
equity investment of $700,000.  Pursuant to a strategic alliance  agreement,  we
provided  Chronix with  $250,000 for  research and  development  in an effort to
develop  intellectual  property on potential  new products  for  diagnosing  and
treating various chronic illnesses such as ME/CFS.  These costs were expensed as
incurred.  The strategic  alliance  agreement provides us certain royalty rights
with respect to certain diagnostic technology developed from this research and a
right of first refusal to license certain therapeutic  technology developed from
this  research.  The  strategic  alliance  agreement  provides us with a royalty
payment of 10% of all net sales of  diagnostic  technology  developed by Chronix
for  diagnosing  Chronic  Fatigue  Syndrome,  Gulf War Syndrome and Human Herpes
Virus-6  associated  diseases.  The royalty continues for the longer of 12 years
from  September 15, 2000 or the life of any patent(s)  issued with regard to the
diagnostic  technology.  The strategic  alliance agreement also provides us with
the right of first refusal to acquire an exclusive worldwide license for any and
all therapeutic  technology developed by Chronix on or before September 14, 2012
for  treating  Chronic  Fatigue  Syndrome,  Gulf War  Syndrome  and Human Herpes
Virus-6  associated  diseases.  During the quarter  ended  December 31, 2002 and
September  30,  2004 we  recorded a noncash  charge of  $292,000  and  $373,000,
respectively, with respect to our investment in Chronix. This impairment reduces
our  carrying  value to reflect a permanent  decline in  Chronix's  market value
based on its then proposed equity offerings.


                                       21


      In March 2002,  our European  subsidiary  Hemispherx  S.A.  entered into a
Sales and  Distribution  agreement  with  Esteve.  Pursuant  to the terms of the
Agreement,  Esteve was  granted the  exclusive  right to market  Ampligen(R)  in
Spain,  Portugal and Andorra for the  treatment of ME/CFS.  In addition to other
terms and other projected  payments,  Esteve agreed to conduct certain  clinical
trials using Ampligen(R) in the patient  population  coinfected with HCV and HIV
viruses.  The Agreement  runs for the longer of ten years from the date of first
arms-length sale in the Territory,  the expiration of the last Hemispherx patent
exploited by Esteve or the period of regulatory  data protection for Ampligen(R)
in the applicable territory. Pursuant to the terms of the agreement Esteve is to
conduct  clinical  trials using  Ampligen(R) to treat patients with both HCV and
HIV and is required to purchase  certain  minimum  annual amounts of Ampligen(R)
following regulatory  approval.  Esteve initiated the HIV/HCV clinical trials in
Spain in late 2004,  but did not proceed  with the trials due to an inability to
enroll a sufficient  number of  patients.  We are  discussing  with Esteve their
initiation  of  another   clinical  trial   utilizing   Ampligen(R)  in  another
indication.  The  agreement  is  terminable  by either party if  Ampligen(R)  is
withdrawn  from the  territory  for a  specified  period due to serious  adverse
health or safety reasons; bankruptcy, insolvency or related issues of one of the
parties;  or material  breach of the  agreement.  Hemispherx  may  transform the
agreement into a non-exclusive agreement or terminate the agreement in the event
that Esteve does not meet specified  percentages of its annual minimum  purchase
requirements  under the  agreement.  Esteve may  terminate  the agreement in the
event  that  Hemispherx  fails to  supply  Ampligen(R)  to the  territory  for a
specified  period  of  time  or  certain  clinical  trials  being  conducted  by
Hemispherx  are not  successful.  The last patent with respect to this agreement
expires on June 5, 2012.

      Recently,  Japanese researchers (Journal of Virology page 2910, 2005) have
found that dsRNAs increase the  effectiveness of influenza  vaccine by more than
300% and may also convey  "cross-protection  ability  against  variant  viruses"
(mutated  strains of influenza  virus).  In October  2005,  we signed a research
agreement with the National Institute of Infectious  Diseases,  in Tokyo, Japan.
The collaboration,  by Hideki Hasegawa,  M.D., Ph.D., Chief of the Laboratory of
Infectious   Disease  Pathology,   will  assess  our  experimental   therapeutic
Ampligen(R) as a co-administered  immunotherapeutic  to the Institution's  nasal
flu vaccine.

      In October  2005,  we also  engaged the Sage Group,  Inc.,  a health care,
technology  oriented,  strategy and  transaction  advisory firm, to assist us in
obtaining a strategic  alliance in Japan for the use of  Ampligen(R) in treating
Chronic  Fatigue  Syndrome  or CFS.  In the past year  leaders  in the  Japanese
medical  community have  established the Japanese Society of the Fatigue Science
and the Osaka City University Hospital opened the Fatigue Clinical Center as the
initial step in their Fatigue Research  Project.  We are in discussions with the
Sage Group,  Inc. to expand its engagement to assist us in obtaining a strategic
alliance in Japan for the use of Ampligen(R) in treating Avian Flu.

      In November  2005,  we entered into an agreement  with Defence R&D Canada,
Suffield  ("DRDC  Suffield"),  an agency of the Canadian  Department of National
Defence,  to evaluate the  antiviral  efficacy of our  experimental  therapeutic
Ampligen(R) and Alferon(R) for protection  against human  respiratory  influenza
virus  infection in well validated  animal  models.  DRDC Suffield is conducting
research and development of new drugs that could potentially  become part of the
arsenal of existing  antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the  respiratory  influenza
virus infection on a mouse-adapted strain of human influenza.


                                       22


      We have  entered  into  agreements  for  consulting  services,  which  are
performed at medical research  institutions and by medical and clinical research
individuals. Our obligation to fund these agreements can be terminated after the
initial funding period,  which generally ranges from one to three years or on an
as-needed monthly basis. During the year ending December 31, 2003, 2004 and 2005
we incurred  approximately  $389,000,  $220,000  and $236,000  respectively,  of
consulting  service  fees under  these  agreements.  These  costs are charged to
research and development expense as incurred.

      On December 9, 2005, we executed a Supply  Agreement with  Hollister-Stier
Laboratories LLC of Spokane,  Washington  ("Hollister-Stier"),  for the contract
manufacturing of Ampligen(R) for a five year term.  Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier  will formulate and bottle
the  Ampligen(R).  In November  2005,  we paid $100,000 as a deposit in order to
initiate the  manufacturing  project.  This deposit was expensed as research and
development  during  the  4th  Quarter  2005.  The  achievement  of the  initial
objectives  described  in  the  agreement,   in  combination  with  our  polymer
production facility under construction in New Brunswick,  N.J., may enable us to
manufacture the raw materials for approximately  10,000 doses of Ampligen(R) per
week. We executed a confidentiality  agreement with Hollister-Stier;  therefore,
we commenced the transfer of our  manufacturing  technology to  Hollister-Stier.
Currently,  Hollister-Stier  has  completed  two  pilot  manufacturing  runs  of
Ampligen(R) for stability testing.

      On February 8, 2006, we executed a Manufacturing and Safety Agreement with
Hyaluron, Inc. ("Hyaluron") of Burlington,  Massachusetts,  for the formulation,
packaging and labeling of Alferon N Injection(R).  Pursuant to the Agreement, we
will supply raw  materials  in  sufficient  quantity  and provide any  pertinent
information to the project.

      The development of our nucleic acid based products requires the commitment
of substantial  resources to conduct the  time-consuming  research,  preclinical
development,  and clinical  trials that are  necessary  to bring  pharmaceutical
products to market and to establish  commercial-scale  production  and marketing
capabilities.  During  our last  three  fiscal  years,  we have  directly  spent
approximately  $12,210,000 in research and development,  of which  approximately
$5,218,000 was expended in the year ended December 31, 2005.  These direct costs
do not include the overhead and  administrative  costs  necessary to support the
research and development effort.

HUMAN RESOURCES

      As of May  26,  2006,  we had 62  personnel  consisting  of 43  full  time
employees,  19 regulatory/research  medical personnel on a part-time basis. Part
time personnel are paid on a per diem or monthly basis. 43 personnel are engaged
in our research,  development,  clinical,  and  manufacturing  effort. 19 of our
personnel perform regulatory, general administration, data processing, including
bio-statistics,  financial and investor  relations  functions.  We have no union
employees and we believe our relationship with our employees is good.

      While we have  been  successful  in  attracting  skilled  and  experienced
scientific personnel,  there can be no assurance that we will be able to attract
or retain the necessary qualified employees and/or consultants in the future.


                                       23


SCIENTIFIC ADVISORY BOARD

      Our Scientific  Advisory Board consists of individuals who we believe have
particular  scientific and medical  expertise in Virology,  Cancer,  Immunology,
Biochemistry and related fields.  These individuals will advise us about current
and long term  scientific  planning  including  research  and  development.  The
Scientific  Advisory Board will hold periodic meetings as needed by the clinical
studies in progress by us. In addition,  individual  Scientific  Advisory  Board
Members sometimes will consult with, and meet informally with our employees. All
members  of the  Scientific  Advisory  are  employed  by  others  and  may  have
commitments to and/or consulting  agreements with other entities,  including our
potential competitors.  Members of the Scientific Advisory Board are compensated
at the rate of $1,000 per meeting attended or per day devoted to our affairs.

ITEM 1A. Risk Factors.

      The following cautionary  statements identify important factors that could
cause our  actual  result to  differ  materially  from  those  projected  in the
forward-looking  statements made in this Form 10-K/A. Among the key factors that
have a direct bearing on our results of operations are:

No assurance of successful product development

      Ampligen(R) and related  products.  The development of Ampligen(R) and our
other related products is subject to a number of significant risks.  Ampligen(R)
may be found to be ineffective or to have adverse side effects,  fail to receive
necessary  regulatory  clearances,  be difficult to  manufacture on a commercial
scale,  be  uneconomical  to market or be precluded  from  commercialization  by
proprietary  right of third  parties.  Our  products  are in  various  stages of
clinical and pre-clinical  development and, require further clinical studies and
appropriate  regulatory  approval  processes  before  any such  products  can be
marketed.  We do not know when, if ever,  Ampligen(R) or our other products will
be generally available for commercial sale for any indication. Generally, only a
small percentage of potential  therapeutic  products are eventually  approved by
the FDA for commercial sale.

      The clinical development of the experimental therapeutic,  Ampligen(R) for
CFS was initiated  approximately  16 years ago. To date federal health  agencies
have yet to reach a consensus  regarding  various  aspects of ME/CFS,  including
parameters of "promising  therapies"  for ME/CFS and which aspects of ME/CFS are
anticipated to be "serious or life-threatening".

      Over  its   developmental   history,   Ampligen(R)  has  received  various
designations,  including  Orphan Drug  Product  Certification  (FDA),  Emergency
(compassionate) Cost Recovery Sales Authorization (FDA) and "promising" clinical
outcome  recognition based on the evaluation of certain summary clinical reports
(AHRQ, Agency Health Research Quality).  However to date, the FDA has determined
it has yet to  receive  sufficient  information  to  support  the  potential  of
Ampligen(R)  to treat a  serious  or life  threatening  aspect  of  ME/CFS.  The
definition  of the  "seriousness  of a  condition",  according  to Guidance  for
Industry  documents  published  in  July  2004 is "a  matter  of  judgment,  but
generally  based  on  its  impact  on  such  factors  as  survival,   day-to-day
functioning,  or the  likelihood  that  the  disease,  if left  untreated,  will
progress  from a less  severe  condition  to a more  serious  one".  The FDA has
recently  requested  a  "complete  and  audited  report  of the Amp 516 study to
determine whether  Ampligen(R) has a clinically  meaningful benefit on a serious
or life  threatening  aspect of ME/CFS in order to evaluate  whether the Amp 516
study results do or do not support a "fast track designation".  The FDA has also
invited us to include a schedule for completion of all ME/CFS studies as well as
a proposed  schedule  for our NDA  submission.  Because  we  believe  our ME/CFS
studies are complete, we intend to request a pre-NDA meeting to obtain advice on
preparing and  submitting  our NDA,  which may eliminate the need for Fast Track
Designation.  Meanwhile,  we will continue with our existing  ongoing efforts to
prepare a complete  and audited  report of our various  studies,  including  the
well-controlled  Amp 516 study.  We are using our best  efforts to complete  the
requisite  reports  including  the  hiring of new staff and  various  recognized
expert  medical/regulatory  consultants,  but can  provide  no  assurance  as to
whether  the  outcome  of  this  large  data   collection   and  filing  process
(approximately  750 patients,  treated more than 45,000 times) will be favorable
or unfavorable, specifically with respect to the FDA's perspective. Also, we can
provide no guidance as to the tentative date at which the compilation and filing
of such data will be complete,  as  significant  factors are outside our control
including,  without  limitation,  the ability and willingness of the independent
clinical  investigators  to  complete  the  requisite  reports at an  acceptable
regulatory  standard,  the ability to collect  overseas  generated data, and the
ability of  Hollister-Stier  facilities to interface  with our own New Brunswick
staff/facilities to meet the manufacturing regulatory standards.


                                       24


      Alferon N  Injection(R).  Although  Alferon N Injection(R) is approved for
marketing in the United States for the intra-lesional treatment of refractory or
recurring  external  genital warts in patients 18 years of age or older; to date
it has not been  approved  for  other  indications.  We face  many of the  risks
discussed  above,  with regard to developing this product for use to treat other
ailments such as multiple sclerosis and cancer.

Our drug and related  technologies are investigational and subject to regulatory
approval. If we are unable to obtain regulatory approval, our operations will be
significantly affected.

      All of our  drugs  and  associated  technologies,  other  than  Alferon  N
Injection(R),  are investigational and must receive prior regulatory approval by
appropriate  regulatory  authorities  for general use and are currently  legally
available only through  clinical  trials with specified  disorders.  At present,
Alferon N  Injection(R)  is only  approved for the  intra-lesional  treatment of
refractory  or recurring  external  genital warts in patients 18 years of age or
older.  Use of  Alferon  N  Injection(R)  for  other  indications  will  require
regulatory approval. In this regard, ISI, the company from which we obtained our
rights to Alferon N  Injection(R),  conducted  clinical trials related to use of
Alferon N Injection(R)  for treatment of HIV and Hepatitis C. In both instances,
the FDA  determined  that  additional  studies were  necessary in order to fully
evaluate  the  efficacy of Alferon N  Injection(R)  in the  treatment of HIV and
Hepatitis C diseases.  We have no immediate  plans to conduct  these  additional
studies at this time.

      Our products,  including Ampligen(R),  are subject to extensive regulation
by numerous governmental authorities in the U.S. and other countries, including,
but not limited to, the FDA in the U.S., the Health Protection Branch ("HPB") of
Canada,  and the Agency for the  Evaluation  of Medicinal  Products  ("EMEA") in
Europe.  Obtaining  regulatory  approvals is a rigorous and lengthy  process and
requires the  expenditure  of  substantial  resources.  In order to obtain final
regulatory  approval of a new drug, we must  demonstrate to the  satisfaction of
the  regulatory  agency that the product is safe and  effective for its intended
uses and that we are  capable of  manufacturing  the  product to the  applicable
regulatory  standards.  We  require  regulatory  approval  in  order  to  market
Ampligen(R)  or any other  proposed  product  and  receive  product  revenues or
royalties. We cannot assure you that Ampligen(R) will ultimately be demonstrated
to be safe or efficacious.  In addition, while Ampligen(R) is authorized for use
in clinical  trials in the United States,  we cannot assure you that  additional
clinical  trial  approvals  will be  authorized in the United States or in other
countries,  in a  timely  fashion  or at all,  or that  we will  complete  these
clinical  trials.  If  Ampligen(R) or one of our other products does not receive
regulatory approval in the U.S. or elsewhere, our operations most likely will be
materially adversely affected.


                                       25


Although  preliminary in vitro testing  indicates that Ampligen(R)  enhances the
effectiveness  of different drug  combinations on avian  influenza,  preliminary
testing in the laboratory is not necessarily predictive of successful results in
clinical testing or human treatment.

      Ampligen(R) is undergoing  pre-clinical  testing for possible treatment of
avian flu.  Although  preliminary in vitro testing  indicates  that  Ampligen(R)
enhances  the  effectiveness  of  different  drug  combinations  on  avian  flu,
preliminary  testing  in  the  laboratory  is  not  necessarily   predictive  of
successful  results in clinical testing or human treatment.  No assurance can be
given  that  similar  results  will  be  observed  in  clinical  trials.  Use of
Ampligen(R)  in the treatment of avian flu requires prior  regulatory  approval.
Only the FDA can  determine  whether a drug is safe,  effective or promising for
treating  a  specific  application.  As  discussed  in the  prior  risk  factor,
obtaining regulatory approvals is a rigorous and lengthy process.

      In addition, Ampligen(R) is being tested on one strain of avian flu. There
are a number of strains and strains  mutate.  No  assurance  can be given that a
Ampligen(R) will be effective on any strains that might infect humans.

We may  continue to incur  substantial  losses and our future  profitability  is
uncertain.

      We began operations in 1966 and last reported net profit from 1985 through
1987. Since 1987, we have incurred  substantial  operating losses, as we pursued
our clinical trial effort and expanded our efforts in Europe. As of December 31,
2005 our accumulated  deficit was  approximately  $147,652,000.  We have not yet
generated  significant  revenues from our products and may incur substantial and
increased  losses in the  future.  We cannot  assure  that we will ever  achieve
significant  revenues from product sales or become profitable.  We require,  and
will continue to require, the commitment of substantial resources to develop our
products.  We  cannot  assure  that  our  product  development  efforts  will be
successfully completed or that required regulatory approvals will be obtained or
that  any  products  will  be  manufactured  and  marketed  successfully,  or be
profitable.

We may require additional financing which may not be available.

      The development of our products will require the commitment of substantial
resources to conduct the time-consuming research,  preclinical development,  and
clinical trials that are necessary to bring  pharmaceutical  products to market.
As of  April  30,  2006,  we had  approximately  $23,900,000  in cash  and  cash
equivalents and short-term investments. These funds should be sufficient to meet
our operating cash requirements, including debt service, for the near term.


                                       26


      On April 12, 2006, we entered into a common stock purchase  agreement with
Fusion Capital Fund II, LLC, pursuant to which Fusion Capital has agreed,  under
certain conditions and with certain limitations, to purchase on each trading day
$100,000 of our common stock up to an aggregate of $50.0 million over a 25 month
period (see "Financing;  Equity Financing" in Item 7.  "Management's  Discussion
and Analysis of Financial  Condition  and Results of  Operations;  Liquidity And
Capital Resources;  Capital Resources" in Part II below). The extent to which we
rely on Fusion Capital as a source of funding will depend on a number of factors
including,  the  prevailing  market  price of our common stock and the extent to
which we are able to secure working capital from other sources.

      If  obtaining  sufficient  financing  from  Fusion  Capital  were to prove
unavailable or prohibitively  dilutive and if we are unable to commercialize and
sell  Ampligen(R)  and/or  increase sales of Alferon N Injection(R) or our other
products,  we will need to secure  another source of funding in order to satisfy
our working capital needs.  Even if we are able to access the full $50.0 million
under the common stock purchase  agreement with Fusion  Capital,  we may need to
raise additional funds through additional equity or debt financing or from other
sources in order to complete the necessary  clinical  trials and the  regulatory
approval processes including the commercializing of Ampligen(R) products.  There
can be no assurances that we will raise adequate funds which may have a material
adverse effect on our ability to develop our products. Also, we have the ability
to curtail  discretionary  spending,  including  some  research and  development
activities, if required to conserve cash.

We may not be  profitable  unless we can  protect  our  patents  and/or  receive
approval for additional pending patents.

      We need to preserve and acquire  enforceable  patents  covering the use of
Ampligen(R) for a particular disease in order to obtain exclusive rights for the
commercial  sale of  Ampligen(R)  for such  disease.  We obtained  all rights to
Alferon N Injection(R),  and we plan to preserve and acquire enforceable patents
covering its use for existing and potentially new diseases. Our success depends,
in large part, on our ability to preserve and obtain patent  protection  for our
products and to obtain and preserve our trade secrets and expertise.  Certain of
our know-how and technology is not patentable,  particularly  the procedures for
the  manufacture of our drug product which are carried out according to standard
operating procedure manuals. We have been issued certain patents including those
on the use of Ampligen(R)  and  Ampligen(R)  in  combination  with certain other
drugs for the  treatment of HIV. We also have been issued  patents on the use of
Ampligen(R) in combination with certain other drugs for the treatment of chronic
Hepatitis  B virus,  chronic  Hepatitis  C virus,  and a  patent  which  affords
protection on the use of Ampligen(R) in patients with Chronic Fatigue  Syndrome.
We have not yet been  issued any  patents  in the  United  States for the use of
Ampligen(R) as a sole treatment for any of the cancers,  which we have sought to
target.  With regard to Alferon N  Injection(R),  we have  acquired from ISI its
patents  for natural  alpha  interferon  produced  from human  peripheral  blood
leukocytes and its  production  process.  We cannot assure that our  competitors
will not seek and  obtain  patents  regarding  the use of  similar  products  in
combination with various other agents,  for a particular target indication prior
to our doing such.  If we cannot  protect our  patents  covering  the use of our
products for a particular  disease,  or obtain additional patents, we may not be
able to successfully market our products.

The  patent  position  of  biotechnology  and  pharmaceutical  firms  is  highly
uncertain and involves complex legal and factual questions.


                                       27


      To date,  no  consistent  policy  has  emerged  regarding  the  breadth of
protection afforded by pharmaceutical and biotechnology patents. There can be no
assurance  that new patent  applications  relating to our products or technology
will result in patents being issued or that, if issued, such patents will afford
meaningful  protection  against  competitors  with  similar  technology.  It  is
generally  anticipated that there may be significant  litigation in the industry
regarding patent and intellectual property rights. Such litigation could require
substantial  resources  from  us and we may not  have  the  financial  resources
necessary to enforce the patent  rights that we hold.  No assurance  can be made
that our patents will provide  competitive  advantages  for our products or will
not be successfully  challenged by  competitors.  No assurance can be given that
patents do not exist or could not be filed which would have a materially adverse
effect on our ability to develop or market our products or to obtain or maintain
any competitive  position that we may achieve with respect to our products.  Our
patents also may not prevent others from developing  competitive  products using
related technology.

There can be no assurance that we will be able to obtain  necessary  licenses if
we cannot enforce  patent rights we may hold. In addition,  the failure of third
parties from whom we currently license certain  proprietary  information or from
whom we may be  required to obtain such  licenses in the future,  to  adequately
enforce their rights to such proprietary information, could adversely affect the
value of such licenses to us.

      If we  cannot  enforce  the  patent  rights  we  currently  hold we may be
required to obtain  licenses from others to develop,  manufacture  or market our
products.  There can be no  assurance  that we would be able to obtain  any such
licenses on  commercially  reasonable  terms,  if at all. We  currently  license
certain proprietary  information from third parties, some of which may have been
developed  with  government  grants  under  circumstances  where the  government
maintained certain rights with respect to the proprietary information developed.
No assurances can be given that such third parties will  adequately  enforce any
rights they may have or that the rights, if any, retained by the government will
not adversely affect the value of our license.

There is no guarantee  that our trade  secrets will not be disclosed or known by
our competitors.

      To protect our rights,  we require  certain  employees and  consultants to
enter into  confidentiality  agreements  with us. There can be no assurance that
these  agreements  will  not be  breached,  that  we  would  have  adequate  and
enforceable  remedies for any breach, or that any trade secrets of ours will not
otherwise become known or be independently developed by competitors.

If our distributors do not market our products successfully, we may not generate
significant revenues or become profitable.

      We have limited  marketing and sales  capability.  We are  dependent  upon
existing and, possibly future, marketing agreements and third party distribution
agreements for our products in order to generate significant revenues and become
profitable.  As a result,  any revenues  received by us will be dependent on the
efforts of third  parties,  and there is no assurance that these efforts will be
successful.  Our  agreement  with Accredo  offers the  potential to provide some
marketing and  distribution  capacity in the United States while agreements with
Biovail  Corporation  and  Laboratorios  Del Dr. Esteve S.A. may provide a sales
force in Canada,  Spain and Portugal.  We also had an agreement  with  Bioclones
(Proprietary),  Ltd  ("Bioclones")  that covered South America,  Africa,  United
Kingdom,  Australia and New Zealand. However, we deem this marketing arrangement
with  Bioclones  void  due  to  the  numerous  and  long  standing  failures  of
performance by Bioclones.  In addition, in December 2004, we initiated a lawsuit
in Federal  Court  identifying  a  conspiratorial  group  seeking  to  illegally
manipulate  our stock for  purposes  of bringing  about the hostile  takeover of
Hemispherx. This conspiratorial group includes Bioclones.


                                       28


      We cannot assure that our domestic or foreign  marketing  partners will be
able  to  successfully  distribute  our  products,  or  that  we will be able to
establish  future  marketing  or third party  distribution  agreements  on terms
acceptable to us, or that the cost of establishing  these  arrangements will not
exceed any product  revenues.  The failure to continue these  arrangements or to
achieve other such  arrangements on  satisfactory  terms could have a materially
adverse effect on us.

There are no long-term  agreements with suppliers of required  materials.  If we
are unable to obtain the  required  raw  materials,  we may be required to scale
back  our  operations  or  stop  manufacturing  Alferon  N  Injection(R)  and/or
Ampligen(R).

      A number of essential  materials  are used in the  production of Alferon N
Injection(R),  including  human  white  blood  cells.  We do not have  long-term
agreements for the supply of any of such materials. There can be no assurance we
can enter into  long-term  supply  agreements  covering  essential  materials on
commercially reasonable terms, if at all.

      There are a limited number of manufacturers in the United States available
to provide the polymers for use in manufacturing Ampligen(R).  At present, we do
not have any  agreements  with  third  parties  for the  supply  of any of these
polymers. We are establishing relevant  manufacturing  operations within our New
Brunswick,  New Jersey  facility for the production of Ampligen(R) raw materials
in order to  obtain  polymers  on a more  consistent  manufacturing  basis.  The
establishment  of an Ampligen(R)  raw materials  production  line within our own
facilities,   while  having  obvious   advantages  with  respect  to  regulatory
compliance (other parts of our 43,000 sq. ft. wholly owned FDA approved facility
are already in compliance for the  manufacture of Alferon N  Injection(R)),  may
delay certain steps in the  commercialization  process,  specifically a targeted
NDA filing.

      If we are unable to obtain or manufacture  the required raw materials,  we
may be required to scale back our  operations or stop  manufacturing.  The costs
and  availability  of  products  and  materials  we need for the  production  of
Ampligen(R)  and the commercial  production of Alferon N Injection(R)  and other
products which we may commercially produce are subject to fluctuation  depending
on a variety  of factors  beyond our  control,  including  competitive  factors,
changes in technology,  and FDA and other governmental regulations and there can
be no assurance  that we will be able to obtain such  products and  materials on
terms acceptable to us or at all.

There is no assurance that  successful  manufacture of a drug on a limited scale
basis  for  investigational  use  will  lead  to  a  successful   transition  to
commercial, large-scale production.

      Small changes in methods of manufacturing,  including commercial scale-up,
may affect the chemical structure of Ampligen(R) and other RNA drugs, as well as
their safety and efficacy,  and can,  among other  things,  require new clinical
studies and affect orphan drug status, particularly,  market exclusivity rights,
if any,  under the Orphan Drug Act. The  transition  from limited  production of
pre-clinical  and clinical  research  quantities  to  production  of  commercial
quantities  of our  products  will involve  distinct  management  and  technical
challenges and will require  additional  management and technical  personnel and
capital to the extent such manufacturing is not handled by third parties.  There
can be no assurance that our manufacturing  will be successful or that any given
product  will  be  determined  to  be  safe  and  effective,  capable  of  being
manufactured economically in commercial quantities or successfully marketed.


                                       29


We have limited manufacturing experience and capacity.

      Ampligen(R)  has been only produced in limited  quantities  for use in our
clinical   trials  and  we  are  dependent   upon  third  party   suppliers  for
substantially  all of the  production  process.  The failure to  continue  these
arrangements or to achieve other such  arrangements on satisfactory  terms could
have a material adverse affect on us. Also, to be successful,  our products must
be  manufactured   in  commercial   quantities  in  compliance  with  regulatory
requirements  and at  acceptable  costs.  To the extent we are  involved  in the
production  process,  our current facilities are not adequate for the production
of our proposed products for large-scale commercialization,  and we currently do
not have adequate personnel to conduct commercial-scale manufacturing. We intend
to  utilize  third-party  facilities  if and when the need  arises or, if we are
unable to do so, to build or acquire commercial-scale  manufacturing facilities.
We will  need to  comply  with  regulatory  requirements  for  such  facilities,
including  those of the FDA pertaining to current Good  Manufacturing  Practices
("cGMP")  regulations.  There can be no assurance  that such  facilities  can be
used,  built,  or  acquired  on  commercially  acceptable  terms,  or that  such
facilities,  if used,  built,  or acquired,  will be adequate for our  long-term
needs.

We may not be profitable unless we can produce  Ampligen(R) or other products in
commercial quantities at costs acceptable to us.

      We  have  never  produced  Ampligen(R)  or any  other  products  in  large
commercial  quantities.  We must  manufacture  our products in  compliance  with
regulatory  requirements in large commercial  quantities and at acceptable costs
in order for us to be profitable. We intend to utilize third-party manufacturers
and/or  facilities if and when the need arises or, if we are unable to do so, to
build  or  acquire  commercial-scale  manufacturing  facilities.  If  we  cannot
manufacture  commercial  quantities  of  Ampligen(R)  or enter into third  party
agreements for its manufacture at costs acceptable to us, our operations will be
significantly  affected.  Also, each production lot of Alferon N Injection(R) is
subject to FDA review and approval prior to releasing the lots to be sold.  This
review and approval process could take considerable  time, which would delay our
having product in inventory to sell.

Rapid technological change may render our products obsolete or non-competitive.

      The pharmaceutical  and biotechnology  industries are subject to rapid and
substantial technological change.  Technological competition from pharmaceutical
and  biotechnology  companies,  universities,  governmental  entities and others
diversifying  into the field is intense  and is expected  to  increase.  Most of
these entities have significantly greater research and development  capabilities
than us, as well as substantial  marketing,  financial and managerial resources,
and represent  significant  competition  for us. There can be no assurance  that
developments by others will not render our products or technologies  obsolete or
noncompetitive  or  that  we will  be  able  to  keep  pace  with  technological
developments.


                                       30


Our products may be subject to substantial competition.

      Ampligen(R).  Competitors may be developing  technologies  that are, or in
the future may be, the basis for competitive  products.  Some of these potential
products  may have an  entirely  different  approach  or means of  accomplishing
similar  therapeutic  effects to products being developed by us. These competing
products may be more  effective and less costly than our products.  In addition,
conventional drug therapy,  surgery and other more familiar treatments may offer
competition  to  our  products.   Furthermore,  many  of  our  competitors  have
significantly  greater  experience  than us in  pre-clinical  testing  and human
clinical trials of  pharmaceutical  products and in obtaining FDA, HPB and other
regulatory  approvals of products.  Accordingly,  our competitors may succeed in
obtaining FDA, HPB or other regulatory  product  approvals more rapidly than us.
There are no drugs approved for commercial  sale with respect to treating ME/CFS
in the United States. The dominant  competitors with drugs to treat HIV diseases
include Gilead Pharmaceutical,  Pfizer, Bristol-Myers,  Abbott Labs, Glaxo Smith
Kline, Merck and Schering-Plough Corp. These potential competitors are among the
largest pharmaceutical  companies in the world, are well known to the public and
the medical  community,  and have  substantially  greater  financial  resources,
product development,  and manufacturing and marketing capabilities than we have.
Although we believe our principal advantage is the unique mechanism of action of
Ampligen(R)  on the  immune  system,  we cannot  assure  that we will be able to
compete.

      ALFERON N Injection(R).  Many potential  competitors are among the largest
pharmaceutical  companies  in the  world,  are well  known to the public and the
medical community,  and have substantially greater financial resources,  product
development,  and manufacturing and marketing capabilities than we have. Alferon
N Injection(R)  currently competes with Schering's injectable  recombinant alpha
interferon  product  (INTRON(R)  A) for  the  treatment  of  genital  warts.  3M
Pharmaceuticals  also  received FDA approval for its  immune-response  modifier,
Aldara(R),  a  self-administered  topical  cream,  for the treatment of external
genital and perianal warts.  Alferon N Injection(R) also competes with surgical,
chemical,  and other  methods of treating  genital  warts.  We cannot assess the
impact products  developed by our  competitors,  or advances in other methods of
the treatment of genital warts, will have on the commercial viability of Alferon
N  Injection(R).  If and when we  obtain  additional  approvals  of uses of this
product, we expect to compete primarily on the basis of product performance. Our
potential  competitors have developed or may develop products (containing either
alpha or beta  interferon or other  therapeutic  compounds)  or other  treatment
modalities for those uses. In the United States, three recombinant forms of beta
interferon have been approved for the treatment of relapsing-remitting  multiple
sclerosis.  There can be no assurance that, if we are able to obtain  regulatory
approval of Alferon N Injection(R) for the treatment of new indications, we will
be able to achieve any significant  penetration into those markets. In addition,
because  certain  competitive  products  are not  dependent on a source of human
blood cells, such products may be able to be produced in greater volume and at a
lower cost than Alferon N Injection(R).  Currently, our wholesale price on a per
unit  basis of Alferon N  Injection(R)  is higher  than that of the  competitive
recombinant alpha and beta interferon products.

      General.  Other companies may succeed in developing  products earlier than
we do,  obtaining  approvals for such products from the FDA more rapidly than we
do, or developing  products that are more  effective  than those we may develop.
While we will  attempt  to expand  our  technological  capabilities  in order to
remain  competitive,  there can be no assurance that research and development by
others or other  medical  advances  will not render our  technology  or products
obsolete or  non-competitive  or result in treatments  or cures  superior to any
therapy we develop.


                                       31


Possible  side effects  from the use of  Ampligen(R)  or Alferon N  Injection(R)
could adversely affect potential revenues and physician/patient acceptability of
our product.

      Ampligen(R). We believe that Ampligen(R) has been generally well tolerated
with a low  incidence  of clinical  toxicity,  particularly  given the  severely
debilitating  or life  threatening  diseases  that  have  been  treated.  A mild
flushing  reaction has been observed in approximately 15% of patients treated in
our various studies. This reaction is occasionally  accompanied by a rapid heart
beat,  a tightness  of the chest,  urticaria  (swelling  of the skin),  anxiety,
shortness of breath,  subjective  reports of "feeling hot," sweating and nausea.
The reaction is usually infusion-rate related and can generally be controlled by
slowing the infusion rate. Other adverse side effects include liver enzyme level
elevations,  diarrhea, itching, asthma, low blood pressure,  photophobia,  rash,
transient  visual  disturbances,  slow or  irregular  heart rate,  decreases  in
platelets and white blood cell counts, anemia, dizziness,  confusion,  elevation
of kidney function tests,  occasional  temporary hair loss and various  flu-like
symptoms,  including  fever,  chills,  fatigue,  muscular  aches,  joint  pains,
headaches,  nausea and vomiting.  These flu-like side effects  typically subside
within  several  months.  One or more of the potential  side effects might deter
usage of  Ampligen(R)  in  certain  clinical  situations  and  therefore,  could
adversely affect potential revenues and  physician/patient  acceptability of our
product.

      Alferon  N  Injection(R).  At  present,  Alferon  N  Injection(R)  is only
approved for the  intra-lesional  (within the lesion) treatment of refractory or
recurring external genital warts in adults. In clinical trials conducted for the
treatment  of  genital  warts  with  Alferon N  Injection(R),  patients  did not
experience  serious  side  effects;  however,  there  can be no  assurance  that
unexpected or unacceptable side effects will not be found in the future for this
use or other  potential uses of Alferon N  Injection(R)  which could threaten or
limit such product's usefulness.

We may be subject  to  product  liability  claims  from the use of  Ampligen(R),
Alferon N Injection(R),  or other of our products which could negatively  affect
our future operations.

      We face an inherent  business risk of exposure to product liability claims
in the event that the use of  Ampligen(R)  or other of our  products  results in
adverse  effects.  This  liability  might  result from  claims made  directly by
patients,  hospitals, clinics or other consumers, or by pharmaceutical companies
or others  manufacturing these products on our behalf. Our future operations may
be negatively  affected from the litigation costs,  settlement expenses and lost
product  sales  inherent to these  claims.  While we will continue to attempt to
take appropriate  precautions,  we cannot assure that we will avoid  significant
product  liability  exposure.  Although we currently  maintain product liability
insurance  coverage,  there can be no assurance that this insurance will provide
adequate  coverage  against  Ampligen(R)  and/or Alferon N Injection(R)  product
liability  claims. A successful  product liability claim against us in excess of
Ampligen(R)'s  $1,000,000 in insurance coverage;  $3,000,000 in aggregate, or in
excess of Alferon N Injection(R)'s $5,000,000 in insurance coverage;  $5,000,000
in aggregate; or for which coverage is not provided could have a negative effect
on our business and financial condition.

The loss of Dr. William A. Carter's services could hurt our chances for success.


                                       32


      Our success is dependent on the continued efforts of Dr. William A. Carter
because of his  position as a pioneer in the field of nucleic  acid  drugs,  his
being  the  co-inventor  of  Ampligen(R),  and  his  knowledge  of  our  overall
activities,  including  patents and clinical  trials.  The loss of Dr.  Carter's
services could have a material  adverse effect on our operations and chances for
success.  We have secured key man life  insurance in the amount of $2,000,000 on
the life of Dr. Carter and we have an employment agreement with Dr. Carter that,
as amended,  runs until December 31, 2010. However,  Dr. Carter has the right to
terminate his employment  upon not less than 30 days prior written  notice.  The
loss of Dr.  Carter or other  personnel,  or the  failure to recruit  additional
personnel  as needed could have a  materially  adverse  effect on our ability to
achieve our objectives.

Uncertainty of health care reimbursement for our products.

      Our ability to  successfully  commercialize  our products will depend,  in
part,  on the extent to which  reimbursement  for the cost of such  products and
related  treatment  will be  available  from  government  health  administration
authorities,   private  health  coverage   insurers  and  other   organizations.
Significant  uncertainty exists as to the reimbursement status of newly approved
health care products,  and from time to time legislation is proposed,  which, if
adopted,   could  further   restrict  the  prices   charged  by  and/or  amounts
reimbursable to  manufacturers  of  pharmaceutical  products.  We cannot predict
what,  if any,  legislation  will  ultimately  be  adopted or the impact of such
legislation  on us.  There  can  be no  assurance  that  third  party  insurance
companies will allow us to charge and receive  payments for products  sufficient
to realize an appropriate return on our investment in product development.

There are  risks of  liabilities  associated  with  handling  and  disposing  of
hazardous materials.

      Our  business   involves  the  controlled  use  of  hazardous   materials,
carcinogenic  chemicals,  flammable solvents and various radioactive  compounds.
Although we believe that our safety  procedures  for  handling and  disposing of
such materials comply in all material respects with the standards  prescribed by
applicable  regulations,  the risk of  accidental  contamination  or injury from
these  materials  cannot  be  completely  eliminated.  In the  event  of such an
accident or the failure to comply with applicable regulations,  we could be held
liable for any damages that result, and any such liability could be significant.
We do not maintain insurance coverage against such liabilities.

Risks Associated With an Investment in Our Common Stock

We reported material weaknesses in our internal control over financial reporting
that, if not remedied, could adversely affect our internal controls.

      We have assessed the  effectiveness of our internal control over financial
reporting as of December 31, 2005. In making this  assessment,  management  used
the  criteria  set forth by the  Committee of  Sponsoring  Organizations  of the
Treadway Commission in Internal  Control--Integrated  Framework (COSO). Based on
this assessment,  management has identified the following material weaknesses as
of  December  31,  2005.  A  material  weakness  is  a  control  deficiency,  or
combination  of  control  deficiencies,  that  results  in  more  than a  remote
likelihood  that a material  misstatement  of the  annual or  interim  financial
statements will not be prevented or detected.


                                       33


      1.    Financial  Statement  Close  and  Reporting  Process  - We  did  not
            maintain effective  controls over the financial  statement close and
            reporting  process  because we lacked a complement of personnel able
            to devote sufficient time and adequate financial reporting expertise
            commensurate with quarterly and year-end  financial  statement close
            requirements,  which include the financial statement preparation and
            disclosures. Additionally, we had inadequate policies and procedures
            providing  for a  detailed  comprehensive  review of the  underlying
            information  supporting  the  amounts  including  in our  annual and
            interim consolidation financial statements and disclosures. The lack
            of  personnel  resources  with  specific  technical  accounting  and
            financial accounting expertise  contributed to the material weakness
            discussed in number two below.

      2.    We did not maintain effective controls over the initial recording of
            our  convertible  debentures  that contained  beneficial  conversion
            features  (including  incorrect recording of investment banking fees
            incurred and subsequent  conversion price resets) and the accounting
            for warrants and options issued to non-employees. Our interpretation
            and application of EITF No. 00-27, FASB Statement 133, EITF 98-5 and
            EITF 00-19 was not  correct at the time the  convertible  debentures
            were  initially   recorded   (2003  through  July  2004),   and  our
            interpretation  and  application  of FASB  statement No. 123 was not
            correct  in  recording  certain  warrant  and  option  issuances  to
            non-employees.   These   control   deficiencies   resulted   in  the
            restatement  of the  2004  and 2003  annual  consolidated  financial
            statements  as  well  as  to  the  unaudited   consolidated  interim
            financial statements for each of the three years in the period ended
            December 31, 2005.

      The result of applying the proper accounting  treatment  increased our net
loss applicable to common  stockholders by $0.01 per share, from $0.42 per share
to $0.43 per share,  for the year ended  December 31, 2003 and decreased our net
loss applicable to common  stockholders by $0.07 per share, from $0.53 per share
to $0.46 per share, for the year ended December 31, 2004.

Although the recording of the convertible debentures occurred during the periods
from March 2003 through July 2004, and we have not issued any  debentures  since
July 2004,  we have taken and plan to take,  during  2006,  additional  steps to
remediate  these internal  control  weaknesses.  In March 2006, we increased the
time allocated by our financial  consultant  with regards to  remediating  these
disclosed  internal control weaknesses and will spend additional time monitoring
our internal  controls on an on-going basis. In addition,  we have subscribed to
CCH's "Accounting  Research  Manager," a recognized  on-line service in order to
maintain  up-to-date  accounting  guidance to enhance internal control over both
financial reporting and disclosure requirements.  Notwithstanding the foregoing,
and the measures we have taken and any future  measures we may take to remediate
the  reported  internal  control  weaknesses,  we may not be  able  to  maintain
effective internal controls over financial reporting in the future. In addition,
deficiencies  in our internal  controls  may be  discovered  in the future.  Any
failure to remediate the reported  material  weaknesses,  or to implement new or
improved controls, or difficulties  encountered in their  implementation,  could
harm our operating results,  cause us to fail to meet our reporting  obligations
or  result in  material  misstatements  in our  financial  statements.  Any such
failure also could affect the ability of our  management  to certify in our 2006
Forms 10-K and 10-Q that our internal controls are effective when it provides an
assessment of our internal  control over financial  reporting,  and could affect
the results of our  independent  registered  public  accounting  firm's  related
attestation report regarding our management's  assessment.  Ineffective internal
controls could also cause investors to lose confidence in our reported financial
information,  which  could have a negative  effect on the  trading  price of our
securities.


                                       34


The market price of our stock may be adversely affected by market volatility.

      The  market  price  of our  common  stock  has been  and is  likely  to be
volatile. In addition to general economic,  political and market conditions, the
price and trading volume of our stock could fluctuate widely in response to many
factors, including:

      o     announcements  of  the  results  of  clinical  trials  by us or  our
            competitors;

      o     adverse reactions to products;

      o     governmental approvals, delays in expected governmental approvals or
            withdrawals  of  any  prior  governmental  approvals  or  public  or
            regulatory agency concerns  regarding the safety or effectiveness of
            our products;

      o     changes in U.S. or foreign  regulatory  policy  during the period of
            product development;

      o     developments in patent or other  proprietary  rights,  including any
            third party challenges of our intellectual property rights;

      o     announcements of technological innovations by us or our competitors;

      o     announcements  of  new  products  or  new  contracts  by us  or  our
            competitors;

      o     actual or anticipated variations in our operating results due to the
            level of development expenses and other factors;

      o     changes in financial  estimates by  securities  analysts and whether
            our earnings meet or exceed the estimates;

      o     conditions and trends in the  pharmaceutical  and other  industries;
            new accounting standards; and

      o     the  occurrence  of  any of  the  risks  described  in  these  "Risk
            Factors."

      Our common stock is listed for quotation on the American  Stock  Exchange.
For the 12-month  period  ended May 31, 2006,  the price of our common stock has
ranged from $1.45 to $3.99 per share. We expect the price of our common stock to
remain  volatile.  The average daily  trading  volume of our common stock varies
significantly.  Our  relatively  low average  volume and low  average  number of
transactions  per day may affect the ability of our  stockholders  to sell their
shares in the public  market at  prevailing  prices and a more active market may
never develop.

      In the past,  following  periods of  volatility in the market price of the
securities of companies in our industry,  securities class action litigation has
often been instituted  against companies in our industry.  If we face securities
litigation in the future, even if without merit or unsuccessful, it would result
in  substantial  costs and a diversion of management  attention  and  resources,
which would negatively impact our business.

Our stock price may be adversely  affected if a significant amount of shares are
sold in the public market.


                                       35


      As of May 26, 2006,  approximately  1,095,882  shares of our common stock,
constituted  "restricted securities" as defined in Rule 144 under the Securities
Act. Also, we are committed to register 27,609,364 shares issuable (i) to Fusion
Capital  pursuant to the April 12, 2006 common  stock  purchase  agreement  with
Fusion Capital; (ii) upon conversion of approximately 135% of Debentures that we
issued in 2003 and 2004;  (iii) as payment of 135% of the interest on all of the
Debentures;  (iv)  upon  exercise  of 135% of  certain  Warrants;  and (v)  upon
exercise of certain other warrants.  Registration of the shares permits the sale
of the shares in the open market or in privately negotiated transactions without
compliance  with the  requirements of Rule 144. To the extent the exercise price
of the warrants is less than the market price of the common  stock,  the holders
of the warrants are likely to exercise  them and sell the  underlying  shares of
common stock and to the extent that the  conversion  price and exercise price of
these  securities  are  adjusted  pursuant  to  anti-dilution  protection,   the
securities  could be exercisable  or convertible  for even more shares of common
stock.  We also may issue shares to be used to meet our capital  requirements or
use shares to compensate employees,  consultants and/or directors. We are unable
to estimate the amount,  timing or nature of future sales of outstanding  common
stock.  Sales of  substantial  amounts of our common stock in the public  market
could cause the market price for our common stock to  decrease.  Furthermore,  a
decline in the price of our common  stock  would  likely  impede our  ability to
raise capital through the issuance of additional shares of common stock or other
equity securities.

The sale of our common stock to Fusion  Capital may cause  dilution and the sale
of the  shares of common  stock  acquired  by Fusion  Capital  and other  shares
registered for selling stockholders could cause the price of our common stock to
decline.

      The sale by Fusion  Capital and other selling  stockholders  of our common
stock will  increase  the number of our  publicly  traded  shares,  which  could
depress the market price of our common  stock.  Moreover,  the mere  prospect of
resales by Fusion  Capital  and other  selling  stockholders  could  depress the
market  price for our common  stock.  The  issuance of shares to Fusion  Capital
under the common stock purchase  agreement dated April 12, 2006, will dilute the
equity interest of existing stockholders and could have an adverse effect on the
market price of our common stock.

      The  purchase  price for the  common  stock to be sold to  Fusion  Capital
pursuant to the common stock  purchase  agreement  will  fluctuate  based on the
price of our common  stock.  All shares sold to Fusion  Capital are to be freely
tradable.  Fusion  Capital  may sell  none,  some or all of the shares of common
stock purchased from us at any time. We expect that the shares will be sold over
a period of in excess of 25 months. Depending upon market liquidity at the time,
a sale of shares  under this  offering at any given time could cause the trading
price of our common stock to decline. The sale of a substantial number of shares
of our common stock to Fusion  Capital  pursuant to the purchase  agreement,  or
anticipation  of such sales,  could make it more difficult for us to sell equity
or  equity-related  securities  in the  future at a time and at a price  that we
might otherwise wish to effect sales.

Provisions of our  Certificate of  Incorporation  and Delaware law could defer a
change of our management which could discourage or delay offers to acquire us.

      Provisions of our Certificate of  Incorporation  and Delaware law may make
it more difficult for someone to acquire  control of us or for our  stockholders
to remove existing management,  and might discourage a third party from offering
to acquire us, even if a change in control or in management  would be beneficial
to our stockholders.  For example, our Certificate of Incorporation allows us to
issue  shares of  preferred  stock  without  any vote or  further  action by our
stockholders.  Our Board of Directors has the authority to fix and determine the
relative rights and preferences of preferred  stock. Our Board of Directors also
has the authority to issue preferred stock without further stockholder approval.
As a result,  our Board of Directors could authorize the issuance of a series of
preferred  stock that would grant to holders the  preferred  right to our assets
upon  liquidation,  the right to receive dividend  payments before dividends are
distributed  to the holders of common stock and the right to the  redemption  of
the  shares,  together  with a premium,  prior to the  redemption  of our common
stock.  In this regard,  in November 2002, we adopted a stockholder  rights plan
and, under the Plan, our Board of Directors declared a dividend  distribution of
one Right for each  outstanding  share of Common Stock to stockholders of record
at the close of business on November 29,  2002.  Each Right  initially  entitles
holders to buy one unit of preferred stock for $30.00.  The Rights generally are
not transferable  apart from the common stock and will not be exercisable unless
and until a person or group  acquires or commences a tender or exchange offer to
acquire,  beneficial ownership of 15% or more of our common stock.  However, for
Dr. Carter, our chief executive officer,  who already  beneficially owns 9.3% of
our common stock,  the Plan's  threshold will be 20%, instead of 15%. The Rights
will expire on November 19, 2012,  and may be redeemed prior thereto at $.01 per
Right under certain circumstances.


                                       36


We have a limited  number of  authorized  shares that are not issued or reserved
for issuance.  If we do not increase our authorized shares, our ability to raise
capital may be hindered.

      Our  Certificate  of  Incorporation  currently  authorizes the issuance of
100,000,000 common shares and 5,000,000 Preferred Shares. As of May 26, 2006, we
had 62,261,349  common shares  outstanding and 35,380,005 common shares reserved
for  future  issuance  under our  existing  stock  option  plan and  outstanding
options, warrants,  convertible debentures, and the 2006 Purchase Agreement with
Fusion,  leaving only 2,358,646 common shares available for future use. In April
2006, our Board of Directors adopted a resolution proposing that our Certificate
of Incorporation  be amended to increase the authorized  number of common shares
to  200,000,000   subject  to  stockholder   approval  of  such  amendment.   If
stockholders do not approve the amendment to our Certificate of Incorporation at
our next Annual  Stockholders  Meeting, it could harm our business by preventing
us from utilizing the daily purchase  amounts  available under the 2006 Purchase
Agreement  in full,  raising  capital  from the  issuance of our common stock or
delaying the payment of services via issuances of our common stock.

      Because the risk factors  referred to above could cause actual  results or
outcomes  to differ  materially  from  those  expressed  in any  forward-looking
statements  made  by us,  you  should  not  place  undue  reliance  on any  such
forward-looking  statements.  Further, any forward-looking statement speaks only
as of the date on which it is made and we undertake no  obligation to update any
forward-looking statement or statements to reflect events or circumstances after
the  date on  which  such  statement  is  made  or  reflect  the  occurrence  of
unanticipated  events.  New  factors  emerge  from  time to time,  and it is not
possible for us to predict which will arise.  In addition,  we cannot assess the
impact of each  factor on our  business  or the extent to which any  factor,  or
combination of factors, may cause actual results to differ materially from those
contained in any  forward-looking  statements.  Our research in clinical efforts
may continue for the next several  years and we may continue to incur losses due
to clinical  costs incurred in the  development  of  Ampligen(R)  for commercial
application.  Possible  losses may fluctuate from quarter to quarter as a result
of  differences in the timing of  significant  expenses  incurred and receipt of
licensing fees and/or cost recovery treatment revenues in Europe,  Canada and in
the United States.

ITEM 2.  Properties.

      We currently lease our headquarters located in Philadelphia,  Pennsylvania
consisting  of a suite of offices of  approximately  15,000 square feet. We also
currently  own,  occupy and use our New  Brunswick,  New Jersey  laboratory  and
production  facility that we acquired from ISI. These facilities  consist of two
buildings located on 2.8 acres. One building is a two story facility  consisting
of a total of 31,300 square feet. This facility contains offices,  laboratories,
production  space and shipping and receiving  areas.  It is also contains  space
designated  for research  and  development,  our  pharmacy,  packaging,  quality
assurance and quality control laboratories.  Building Two has 11,670 square feet
consisting  of offices,  laboratories  and  warehouse  space.  The  property has
parking space for approximately 100 vehicles.

      In 2005, we initiated the transfer of Ampligen(R) raw materials production
to our own facilities, which is now completed and in production. This transition
of Ampligen(R)  raw material  production has obvious  advantages with respect to
overall control of the  manufacturing  procedure of Ampligen(R)'s raw materials,
keeping costs down and controlling  regulatory compliance issues (other parts of
the of our 43,000 sq. ft.  wholly  owned FDA  approved  facility  are already in
compliance for Alferon N Injection(R)  manufacture).  This will also allow us to
obtain Ampligen(R) raw materials on a more consistent manufacturing basis. As of
April  30,  2006,  we have  capitalized  approximately  $1,400,000  towards  the
construction  and  installation  of  this  production  line  at our  New  Jersey
facility.  The  installation  of a raw material  production  line within our New
Brunswick  facility has been  completed and is now in production  with the first
lot of  Ampligen(R)  raw material  being produced in the second quarter 2006. We
estimate  the  total  cost  of  establishing  this  production  line  to be some
$1,900,000,  including modifications to our New Brunswick facility. This polymer
production line will have the capacity to produce up to four kilograms per week,
or 100  kilograms per year which should allow us to  manufacture  up to one-half
million 400 mg doses per year.

      Our lease on the Rockville  facility expired in June 2005 and we completed
the  move  of our  laboratory  and  equipment  to our  New  Brunswick  facility.
Consolidation  of this laboratory with our existing  laboratory in New Brunswick
will provide  economical  benefit.  With the consolidation  complete,  it is our
belief that the  consolidated  facility will enable us to meet our  requirements
for planned clinical trials and treatment protocols for the foreseeable future.

ITEM 3.  Legal Proceedings.

      On September 30, 1998, we filed a multi-count  complaint against Manuel P.
Asensio,  Asensio & Company,  Inc.  ("Asensio").  The action  included claims of
defamation,  disparagement,  tortuous interference with existing and prospective
business relations and conspiracy, arising out of Asensio's false and defamatory
statements. The complaint further alleged that Asensio defamed and disparaged us
in furtherance of a manipulative, deceptive and unlawful short-selling scheme in
August and September,  1998. In 1999,  Asensio filed an answer and  counterclaim
alleging  that in response to  Asensio's  strong sell  recommendation  and other
press  releases,  we made  defamatory  statements  about Asensio.  We denied the
material  allegations of the counterclaim.  In July 2000, following dismissal in
federal court for lack of subject matter jurisdiction, we transferred the action
to the Pennsylvania State Court. In March 2001, the defendants  responded to the
complaints as amended and a trial  commenced on January 30, 2002. A jury verdict
disallowed the claims  against the  defendants for defamation and  disparagement
and the court granted us a directed verdict on the counterclaim. On July 2, 2002
the  Court  entered  an  order  granting  us a new  trial  against  Asensio  for
defamation and disparagement. Thereafter, Asensio appealed the granting of a new
trial to the Superior Court of Pennsylvania.  The Superior Court of Pennsylvania
has  denied  Asensio's   appeal.   Asensio   petitioned  the  Supreme  Court  of
Pennsylvania for allowance of an appeal, which was denied. We now anticipate the
scheduling of a new trial against  Asensio for defamation and  disparagement  in
the Philadelphia Common Pleas Court.


                                       38


      In June 2002, a former ME/CFS clinical trial patient and her husband filed
a claim in the Superior Court of New Jersey,  Middlesex County,  against us, one
of our clinical trial  investigators  and others alleging that she was harmed in
the ME/CFS clinical trial as a result of negligence and breach of warranties. On
June 25, 2004 all claims against us were dismissed  with  prejudice.  The former
ME/CFS clinical trial patient and her husband have now appealed the dismissal of
their claims to the New Jersey Superior  Court,  Apellate  Division,  upheld the
dismissal of all claims against us and the matter is now concluded.

      In June 2002, a former  ME/CFS  clinical  trial patient in Belgium filed a
claim in  Belgium,  against  Hemispherx  Biopharma  Europe,  NV/SA,  our Belgian
subsidiary,  and one of our clinical trial  investigators  alleging that she was
harmed in the Belgium ME/CFS clinical trial as a result of negligence and breach
of  warranties.  We believe the claim is without  merit and we are defending the
claim against us through our product liability insurance carrier.

      In  December  2004,  we filed a  multicount  complaint  in  federal  court
(Southern  District  of  Florida)  against a  conspiratorial  group  seeking  to
illegally manipulate our stock for purposes of bringing about a hostile takeover
of Hemispherx.  The lawsuit alleges that the conspiratorial group commenced with
a plan to seize  control  of our  cash  and  proprietary  assets  by an  illegal
campaign to drive down our stock price and  publish  disparaging  reports on our
management and current fiduciaries. The lawsuit seeks monetary damages from each
member of the  conspiratorial  group as well as injunctions  preventing  further
recurrences of their misconduct.  The conspiratorial group includes Bioclones, a
privately held South African  Biopharmaceutical  company that  collaborated with
us, and  Johannesburg  Consolidated  Investments,  a South African  corporation,
Cyril Donninger, R. B. Kebble, H. C. Buitendag,  Bart Goemaere, and John Doe(s).
Bioclones,  Johannesburg Consolidated Investments, Cyril Donninger, R. B. Kebble
and H.C. Buitendag filed a motion to dismiss the complaint, which was granted by
the court.  We are in the process of appealing this decision to the 11th federal
circuit court of appeals.

      On January  10,  2005,  we  initiated a  multicount  lawsuit in the United
States  District  Court  for  the  Eastern  District  of  Pennsylvania   seeking
injunctive  relief and damages against a conspiratorial  group, many of whom are
foreign  nationals or companies  located outside the United States alleging that
the conspiratorial group has engaged in secret meetings,  market  manipulations,
fraudulent  misrepresentations,  utilization  of foreign  accounts  and  foreign
secrecy laws all in furtherance of an illegal scheme to take over Hemispherx and
enrich  themselves  at the  expense  of  Hemispherx's  public  shareholders.  On
February  18, 2005 we filed an amended  complaint  in the same  lawsuit  joining
Redlabs,   USA,  Inc.  as  a  defendant  with  the  existing  defendants  R.E.D.
Laboratories,  N.V./S.A.,  Bart Goemaere,  Jan Goemaere,  Dr. Kenny De Meirleir,
Kenneth Schepmans,  Johan Goossens,  Lieven Vansacker and John Does. Pursuant to
an agreement in which R.E.D.  Laboratories,  N.V./S.A.  and Dr. Kenny DeMeirleir
agreed not to  participate  in a hostile  takeover of Hemispherx for a period of
five years, R.E.D.  Laboratories,  N.V./S.A.  and Dr. Kenny DeMeirleir have been
dismissed as defendants in the litigation.  The litigation is proceeding against
the remaining defendants.

ITEM 4.  Submission of Matters to a Vote of Security Holders.

      No matters were  submitted to a vote of the  security  holders  during the
last quarter of the year ended December 31, 2005.

ITEM 5. Market for Registrant's  Common Equity,  Related Stockholder Matters and
Issuer Purchases of Equity Securities

      In 2005 we  issued  6,632,389  shares  of common  stock  consisting  of 1)
1,614,628  shares for debt  repayment,  debt  conversion  and interest  payments
related to the October 2003, January 2004 and July 2004 Convertible  Debentures;
2) 338,995  shares in payment of services  rendered 3) 4,673,766  shares  issued
pursuant to the 2005 Purchase  Agreement with Fusion Capital and 4) 5,000 shares
issued upon conversion of warrants.

      The foregoing issuances of securities were private transactions and exempt
from  registration  under section 4(2) of the Securities Act and/or regulation D
rule 506  promulgated  under the Securities  Act. These  securities have been or
will be registered with the SEC.

      Since  October  1997 our  common  stock has been  listed and traded on the
American Stock Exchange  ("AMEX") under the symbol HEB. The following table sets
forth the high and low list prices for our Common  Stock for the last two fiscal
years as reported by the AMEX. Such prices reflect inter-dealer prices,  without
retail markup, markdowns or commissions and may not necessarily represent actual
transactions.

      On April 3,  2006,  we  received a notice  from the staff of The  American
Stock Exchange ("AMEX")  indicating that we were not in compliance with Sections
134 and 1101 of the AMEX  Company  Guide and our  listing  agreement  due to our
failure  to file our  annual  report  on Form  10-K for the  fiscal  year  ended
December 31, 2005 with audited financial  statements on a timely basis. The AMEX
has granted an extension of the listing of our common stock until June 30, 2006,
provided  that we file our Form 10-K for 2005 by June 2, 2006 and provided  that
we file our Form 10-Q for the first quarter of 2006 by June 30, 2006. During the
extension  period,  we will be subject to periodic  review by AMEX staff.  If we
fail to meet any of the foregoing deadlines, the AMEX has indicated that it will
begin delisting proceedings.

      As of May 26, 2006, there were  approximately 278 holders of record of our
Common Stock. This number was determined from records maintained by our transfer
agent and does not include  beneficial owners of our securities whose securities
are held in the names of various dealers and/or clearing agencies.

      On May 26, 2006,  the last sale price for our common stock on the AMEX was
$2.74 per share.

      We have not paid any dividends on our Common Stock in recent years.  It is
management's  intention not to declare or pay dividends on our Common Stock, but
to retain earnings, if any, for the operation and expansion of our business.

      The following table gives  information  about our Common Stock that may be

ITEM 7. Management's  Discussion and Analysis of Financial Condition and Results
of Operations.

      The  following  discussion  and  analysis  is  related  to  our  financial
condition and results of operations for the three years ended December 31, 2005.
This information should be read in conjunction with Item 6 - "Selected Financial
Data" and our  consolidated  financial  statements  and  related  notes  thereto
beginning on F-1 of this Form 10-K/A.

Statement of Forward-Looking Information

      Certain  statements in the section are  "forward-looking  statements." You
should read the  information  before  Item 1B above,  "Special  Note"  Regarding
Forward-Looking  Statements"  for more  information  about our  presentation  of
information.

Background

      We have  reported net income only from 1985 through  1987.  Since 1987, we
have incurred,  as expected,  substantial operating losses due to our conducting
clinical testing.

      In the  course of  almost  three  decades,  we have  established  a strong
foundation  of  laboratory,  pre-clinical  and clinical data with respect to the
development of nucleic acids to enhance the natural  antiviral defense system of
the human body and the development of therapeutic  products for the treatment of
chronic diseases.  Our strategy is to obtain the required  regulatory  approvals
which will allow the progressive  introduction of Ampligen(R)  (our  proprietary
drug)  for  treating   Myalgic   Encephalomyelitis/   Chronic  Fatigue  Syndrome
("ME/CFS"),  HIV,  Hepatitis  C ("HCV")  and  Hepatitis  B ("HBV")  in the U.S.,
Canada,  Europe and Japan.  In 2004, we completed a phase III clinical  trial in
the U.S. for use of Ampligen(R) in treatment of ME/CFS and are in the process of
assembling and analyzing the obtained data  preparatory to completing and filing
a New Drug  Application  with the FDA. We are also testing  Ampligen(R) in Phase
IIb Clinical  Trials in the U.S. for the treatment of newly emerging  multi-drug
resistant  HIV, and for the induction of cell mediated  immunity in HIV patients
that are under control using potentially toxic drug cocktails.

      Our  proprietary   drug  technology   utilizes   specifically   configured
ribonucleic  acid ("RNA") and is  protected by more than 100 patents  worldwide,
with  over  9  additional  patent   applications   pending  to  provide  further
proprietary protection in various international  markets.  Certain patents apply
to the  use of  Ampligen(R)  alone  and  certain  patents  apply  to the  use of
Ampligen(R) in combination with certain other drugs. Some compositions of matter
patents  pertain to other new RNA compounds,  which have a similar  mechanism of
action.


                                       43


      In March 2003 we obtained from Interferon  Sciences,  Inc.  ("ISI") all of
its raw materials, work-in-progress and finished product Alferon N Injection(R),
together with a limited license to sell Alferon N Injection(R),  a natural alpha
interferon  that has been approved for  commercial  sale for the  intra-lesional
treatment of refractory or recurring external  condylomata  acuminata  ("genital
warts")  in  patients  18 years of age or older in the United  States.  In March
2004, we acquired from ISI the balance of ISI's rights to its product as well as
ISI's  production  facility.  We are marketing the Alferon N Injection(R) in the
United  States   through   sales   facilitated   via  third  party   agreements.
Additionally,  we intend to implement  studies testing the efficacy of Alferon N
Injection(R)  in multiple  sclerosis and other chronic viral  diseases.  In this
regard,  the FDA  recently  authorized  a Phase II  clinical  study  designed to
investigate  the  activity  and  safety  of  Alferon(R)  LDO in early  stage HIV
positive patients.

      We were  incorporated  in  Maryland  in 1996 under the name HEM  research,
Inc.,  and originally  served as a supplier of research  support  products.  Our
business was  redirected in the early 1980's to the  development of nucleic acid
pharmaceutical  technology  and  the  commercialization  of RNA  drugs.  We were
reincorporated in Delaware and changed our name to Hem  Pharmaceutical  Corp. in
1991 and to Hemispherx  Biopharma,  Inc.,  in June 1995. We have three  domestic
subsidiaries BioPro Corp., BioAegean Corp., and Core BioTech Corp., all of which
are incorporated in Delaware and are dormant.  Our foreign  subsidiaries include
Hemispherx  Biopharma  Europe  N.V./S.A.  established  in  Belgium  in 1998  and
Hemispherx  Biopharma Europe S.A.  incorporated in Luxembourg in 2002 which have
little or no activity.

Restatements

      In 2003 and 2004 we, entered into convertible debenture arrangements which
are  inherently  complicated,  which have been and continue to be the subject of
numerous intricate  accounting  pronouncements and interpretations and which are
not  classified as normal  recurring  transactions.  Our  convertible  debenture
transactions were reported within our previously filed financial  statements for
the years  ended  December  31,  2003 and 2004.  After an  extensive  review and
consultation with our independent  registered  public  accountants and our audit
committee,   we  determined  that  we  must  restate  our  historical  financial
statements for the years ended December 31, 2003 and 2004 as well as the interim
financial statements for 2003, 2004, and 2005. Specifically,  we have determined
that,  with  respect  to the  accounting  for the  convertible  debentures,  the
interpretation and application of EITF No. 00-27: "Application of Issue No. 98-5
to Certain Convertible  Instruments" was not correct at the time the convertible
debentures were initially  recorded and upon conversion  price resets related to
the convertible debentures.  As a result of this determination,  we restated our
financial statements and quarterly results of operations (unaudited) included in
this  annual  report  and  are in the  process  of  restating  the  consolidated
condensed interim  financial  statements for the 2005 and 2004 periods contained
in our 2005 quarterly  reports on Form 10-Q. The  modifications  in the restated
financial statements relate to non-cash charges that do not affect our revenues,
cash flows from operations or liquidity.  These restated  financials  reflect an
increase  in per share loss to common  stockholders  of $0.01 for the year ended
December  31,  2003 and a decrease in per share loss to common  stockholders  of
$0.07 for the year ended December 31, 2004.


                                       44


      (a)Based  on SEC  guidance  presented  at the 2005 annual  AICPA  National
Conference on current SEC and PCAOB developments, we re-evaluated the accounting
for our  March  2003,  July  2003,  October  2003,  January  2004 and July  2004
Debentures  (collectively,  "the  Debentures") to determine whether the embedded
conversion options required  bifurcation and fair value accounting in accordance
with FASB Statement No. 133, "Accounting for Derivative  Instruments and Hedging
Activities",  and EITF 00-19,  "Accounting for Derivative Financial  Instruments
Indexed to, and Potentially Settled in a Company's Own Stock". We concluded that
bifurcation was not required and that EITF 00-27should have been applied. We did
initially  apply EITF 00-27,  however as part of  performing  an analysis on the
guidelines set forth in EITF 00-27 it was determined that the initial accounting
treatment and subsequent  price resets for the Debentures  that were  originally
applied and reflected in the financial  statements included in our Annual Report
on Form  10-K  for the  years  ended  December  31,  2003 and  2004,  and in our
Quarterly Reports on Form 10-Q during the quarterly periods in fiscal 2003, 2004
and 2005 were not correctly  applied and that,  therefore,  a restatement of the
our financial  statements  for the periods  referenced  above was  required.  To
properly account for the initial  calculation of the discount and the conversion
price  resets  triggered  upon the  issuance of the issuance of the October 2003
Debenture  and  the  August  2004  Private  Placement  (See  Notes  8 & 9 to the
consolidated  financial  statements  contained  herein for more details on these
resets),  it was  determined,  under  guidance  from  EITF  00-27  that the debt
discount  should  be  restated  for the  Debentures.  The  total  impact of this
restatement  on our  statement  of  operations  was to  decrease  the  net  loss
applicable  to common  stockholders  for the year  ended  December  31,  2004 by
$2,959,000 or $0.07 per share, and to increase the net loss applicable to common
stockholders  by  $287,000  or $0.01 per share for the year ended  December  31,
2003.

      (b)The  estimation of fair value ascribed to and the accounting  treatment
of the investment  banking fees paid to Cardinal  Capital,  LLC  ("Cardinal") in
connection  with  the  Debenture  issuances,  at  inception,   was  inaccurately
reflected in the financial statements included in our Annual Report on Form 10-K
for the years ended  December 31, 2003 and 2004,  and our  Quarterly  reports on
Form 10-Q for the periods ended March 31, 2005,  June 30, 2005 and September 30,
2005 and that,  therefore,  a restatement  of our financial  statements  for the
periods referenced above was required.  In connection with the initial recording
of the Debentures  mentioned above, it was determined that the fair value of the
warrants issued as investment banking fees paid to Cardinal, be accounted for as
a discount to the  Debentures.  These  investment  banking fees should have been
capitalized  as  deferred  financing  costs and  amortized  over the life of the
Debentures  or  charged  to  earnings  on the  earlier  conversion  thereof.  In
addition,  the initial  calculation of the fair value of the warrants  issued to
Cardinal as part of the Debenture  issuances was determined to have been applied
incorrectly at the time of issuance. The total impact of this restatement on our
statement  of  operations  was to  decrease  the net loss  applicable  to common
stockholders  for the year ended  December  31,  2004 by  $263,000  or $0.01 per
share,  and to increase the net loss applicable to common  stockholders  for the
year ended December 31, 2003 by $158,000 or $0.00 per share.

      (c)The  accounting   treatment  set  forth  in  FASB  Statement  No.  123,
"Accounting  for Stock-Based  Compensation",  for the issuance of the June 2008,
May 2009 and June 2009 Warrants  (collectively "the Warrants")(See Note 8 in the
consolidated  financial  statements  contained  herein for more  detail on these
transactions)  that was  originally  interpreted  and reflected in the financial
statements  included  in our  Annual  Report  on Form  10-K for the  year  ended
December 31, 2003 and 2004,  was not correctly  applied and that,  therefore,  a
restatement  of our financial  statements  for the period  referenced  above was
required.  The warrants issued as incentive to exercise prior warrant  issuances
are  reflected as a deemed  dividend at the date of issuance,  where  previously
these  warrants  were  either  recorded  as  additional  debt  discount  or as a
financing  charge at date of issuance.  The total impact of this  restatement on
our statement of operations  was to decrease  non-cash  finance  charges for the
years ended  December 31, 2003 and 2004 by $1,320,000 and  $4,031,000,  or $0.04
and  $0.08  per  share,  respectively,  and  increase  the net  loss  to  common
stockholders  for the years ended  December  31, 2003 and 2004 due to the deemed
dividend  by  $1,320,000  and   $4,031,000,   or  $0.04  and  $0.08  per  share,
respectively.


                                       45


      As a result of the  corrections  of the errors as of December 31, 2004 and
for the years ended December 31, 2003 and 2004 described above, we have restated
our  consolidated  financial  statements  in this amended  Annual Report on Form
10-K/A.

Result of Operations

Years Ended December 31, 2005 vs. 2004 (restated)

Net loss applicable to common stockholders

      Our net loss applicable to common stockholders of $12,446,000 for the year
ended  December  31, 2005 was down 41%  compared to the same period in 2004,  as
restated.  This  reduction of  $8,472,000 in loss was primarily due to: 1) lower
costs  associated  with non-cash  financing  charges  related to our convertible
debentures  and  related  warrants.  These  non-cash  financing  costs were down
$2,557,000  and  represents 58% of the change in net loss from period to period,
2)  production/cost  of goods  sold  expenditures  were down  $1,721,000  due to
increased  expenditures  during  2004  associated  with  ramping  up of the  New
Brunswick facility for further  production of Alferon N Injection(R),  3) deemed
dividend of  $4,031,000  recorded upon the issuance of warrants to our debenture
holders as incentive to exercise  prior warrant  issuances in 2004, and 4) lower
non-cash stock compensation  expenses of approximately  $1,609,000.  These lower
expenses were slightly offset by an increase in research & development ("R & D")
costs during the current period of approximately  $1,376,000 mainly due to costs
associated  with the future  manufacture on technology at  Hollister-Stier,  our
contract manufacturer of Ampligen(R).  Net loss applicable to common stockholder
per share was $(.24) for the current  period versus $(.46) in the same period in
2004, as restated.


                                       49


      The  stock  compensation  expense  noted  above  is  due  to  a  one-time,
non-recurring  event in that  1,450,000  warrants  were granted to Dr. Carter in
2003 and fully expensed in the amount of $1,769,000 upon vesting in 2004.  These
warrants  were granted in exchange for Dr.  Carter  agreeing not to exercise his
warrants/options  unless,  or until,  stockholders  approved  an increase in our
authorized  shares.  This  agreement  with Dr. Carter allowed us to complete the
July 2003 Debenture transactions.

Revenues

      Total  revenues for the year ended  December 31, 2005 were  $1,083,000  as
compared to $1,229,000 for the same period in 2004. Alferon N Injection(R) sales
of $910,000 in 2005 were down $140,000 or 13% while  Ampligen(R)  sold under the
cost recovery  clinical  program was down $6,000 or 3%. The decline in Alferon N
Injection(R)  sales  can be  attributed  to  increased  competition  from  rival
products,  specifically,  3M Pharmaceutical's  product Aldera.  Ampligen(R) sold
under the cost recovery  clinical  program is a product of physicians and ME/CFS
patients applying to us to enroll in the program.  After screening the patient's
enrollment  records,  we ship Ampligen(R) to the physician.  A typical six-month
treatment  therapy costs the patient about $7,200 for Ampligen(R).  This program
has been in  effect  for many  years and is  offered  as a  treatment  option to
patients severely affected by ME/CFS.  As the name "cost recovery"  implies,  we
have no gain or profit on these sales.  The benefits to us include 1) physicians
and patients  becoming  familiar with  Ampligen(R) and 2) collection of clinical
data relating to the patients' treatment and results.

Production costs/cost of goods sold

      Our costs for  production/cost  of goods sold were down $1,721,000 for the
year ended December 31, 2005 compared to the same period in 2004.  $1,642,000 of
this decrease in production costs is primarily due to expenses  incurred in 2004
related to preparing the New Brunswick  facility for the production of Alferon N
Injection(R). There were no such costs in 2005. We are nearing completion of the
construction of the production line within our own facility in New Brunswick for
Ampligen(R)  raw materials  which was started in 2005.  This  installation  will
increase  production  capacity,  improve  efficiency and assure  compliance with
worldwide drug manufacturing standards and processes.

      Alferon N Injection(R)  cost of goods sold for the year ended December 31,
2005 and 2004 were  $391,000 and  $470,000,  respectively.  Since  acquiring the
right to manufacture  and market  Alferon N Injection(R)  in March 2003, we have
converted the  work-in-progress  inventory into finished  goods as needed.  This
work-in-progress   inventory   included  three   production  lots  totaling  the
equivalent  of  approximately  55,000  vials  (doses) at  various  stages of the
manufacturing  process.  Approximately  42,000  vials  have been  produced.  Our
contractor, Hospira completed the labeling and packaging of approximately 12,000
vials of Alferon N  Injection(R)  inventory  and these vials were  released into
finished goods inventory in November 2005. Hospira gave notice that they will no
longer  label and package  Alferon N  Injection(R)  as they are  seeking  larger
production   runs  for  cost  efficiency   purposes.   We  have  identified  two
manufacturers  to replace  Hospira  and,  on  February  8, 2006,  we  executed a
Manufacturing  and  Safety  Agreement  with  Hyaluron,   Inc.   ("Hyaluron")  of
Burlington,  Massachusetts,  for the  formulation,  packaging  and  labeling  of
Alferon N Injection(R).  Pursuant to the Agreement, we will supply raw materials
in sufficient  production  quantities and provide  technical  information to the
project.


                                       50


      We have started preliminary work to convert the third lot of approximately
13,000 vials to finished goods inventory with an anticipated completion date for
the third quarter  2006. By the first quarter 2007, we anticipate  preparing new
Alferon N Injection(R)  lots from blood  leukocytes at our New Jersey  facility.
Final formulation and packaging of Alferon N Injection(R)  would be completed by
a third party contractor as noted above.

      The installation of a Ampligen(R) raw material  production line within our
New Brunswick facility has been completed and is now in production. The transfer
of  Ampligen(R)  raw  material  production  to our own  facilities  has  obvious
advantages with respect to overall control of the manufacturing process, keeping
costs down and  controlling  regulatory  compliance  issues  (other parts of our
43,000 sq. ft. wholly owned FDA approved  facility are already in compliance for
Alferon  N  Injection(R)  manufacture).  This  will  also  allow  us  to  obtain
Ampligen(R)  raw materials on a more  consistent and reliable basis. As of April
30, 2006, we have capitalized  approximately $1,400,000 towards the construction
and  installation of this production  line. The anticipated  completion date for
the first lot of  Ampligen(R)  raw material being produced is the second quarter
2006. We estimate the total cost of establishing this production line to be some
$1,900,000,  including modifications to our New Brunswick facility. This polymer
production line will have the capacity to produce up to four kilograms per week,
or 100  kilograms per year which should allow us to  manufacture  up to one-half
million 400 mg doses per year. We have identified  three contract  manufacturers
to expand polymer manufacture,  if necessary, and obtained preliminary proposals
from two and initiated discussions with the third.

Research and Development costs

      Overall research and development  direct costs for the year ended December
31, 2005 and 2004 were $5,218,000 and $3,842,000,  respectively.  These costs in
2005  reflect the direct  costs  associated  with our effort to develop our lead
product,  Ampligen(R),  as a therapy in treating chronic  diseases,  cancers and
on-going clinical trials involving  patients with HIV. In addition,  these costs
reflect direct costs incurred relating to the development of Alferon(R) LDO (low
dose  oral  interferon  alfa-N3,   human  leukocyte   derived).   We  have  over
approximately  130,000 doses on hand of Alferon(R)  LDO which have been prepared
for use in clinical trials treating  patients  affected with the SARS, Avian Flu
or other potentially emerging infectious diseases.

      During 2005, we increased our clinical  staff by employing  several highly
trained  individuals to focus on the  preparation of our Ampligen(R) NDA filing.
The NDA filing is a very  complex  document and we are being  meticulous  in the
preparation  of the  document.  Our clinical  monitors  and research  assistants
completed the process of visiting the multiple  clinical  study sites around the
country for our AMP 516 study in January 2006. Our process  included  collecting
and  auditing  data  generated  at  each  of  these  sites.  Since  we  are  now
incorporating  a larger sample of data from our previous trials for inclusion in
the NDA filing  (see below for  further  details),  our  clinical  monitors  and
research assistants plan on visiting our sites associated with our AMP 511 study
in 2006 with the intention of collecting and auditing this additional  data. All
data must be reviewed and checked to clarify any inconsistencies or inaccuracies
that turn up. Due to the human  factor,  these  types of  problems  occur in all
clinical trials.  These gaps and  inconsistencies  in data must be resolved with
the  respective  clinical  investigators,  while  maintaining  a clear record of
events which allows the FDA to conduct a meaningful audit of these records.


                                       51


      We believe  that our AMP 516 ME/CFS  Phase III  clinical  trial for use of
Ampligen(R)  in the  treatment  of ME/CFS is the most  comprehensive  study ever
conducted in ME/CFS.  This Phase III clinical trial,  which was conducted over a
six-year  period,  involved an enrollment of more than 230 severely  debilitated
ME/CFS  patients and was  conducted at twelve  medical  centers  throughout  the
United  States.  The  study is  serving  as the  basis for us to file a new drug
application with the FDA.

      We had  originally  targeted  a late  2004  filing  date  for this NDA for
Ampligen(R).  In order to respond to changes in the regulatory  environment that
place a greater emphasis on the safety and efficacy of all new experimental drug
candidates,  we are now  incorporating a larger sample of data from our previous
trials.   The  NDA  filing  will  now  include  data   accumulated  from  45,000
administrations  of the studied drug to approximately  750 ME/CFS  patients.  We
plan to complete and file the NDA before year end 2006.

      The clinical development of the experimental therapeutic,  Ampligen(R) for
ME/CFS was initiated approximately 16 years ago. To date federal health agencies
have yet to reach a consensus  regarding  various  aspects of ME/CFS,  including
parameters of "promising  therapies"  for ME/CFS and which aspects of ME/CFS are
anticipated to be "serious or life-threatening".

      Over  its   developmental   history,   Ampligen(R)  has  received  various
designations,  including  Orphan Drug  Product  Certification  (FDA),  Emergency
(compassionate) Cost Recovery Sales Authorization (FDA) and "promising" clinical
outcome  recognition based on the evaluation of certain summary clinical reports
(AHRQ, Agency Health Research Quality).  However to date, the FDA has determined
it has yet to  receive  sufficient  information  to  support  the  potential  of
Ampligen(R)  to treat a  serious  or life  threatening  aspect  of  ME/CFS.  The
definition  of the  "seriousness  of a  condition",  according  to Guidance  for
Industry  documents  published  in July,  2004 is "a  matter  of  judgment,  but
generally  based  on  its  impact  on  such  factors  as  survival,   day-to-day
functioning,  or the  likelihood  that  the  disease,  if left  untreated,  will
progress  from a less  severe  condition  to a more  serious  one".  The FDA has
recently  requested  a  "complete  and  audited  report  of the Amp 516 study to
determine whether  Ampligen(R) has a clinically  meaningful benefit on a serious
or life  threatening  aspect of ME/CFS in order to evaluate  whether the Amp 516
study results do or do not support a "fast track designation".  The FDA has also
invited us to include a schedule for completion of all ME/CFS studies as well as
a proposed  schedule  for our NDA  submission.  Because  we  believe  our ME/CFS
studies are complete, we intend to request a pre-NDA meeting to obtain advice on
preparing  and  submitting  our NDA. At the same time we will  continue with our
existing ongoing efforts to prepare a complete and audited report of our various
studies,  including  the  well-controlled  Amp 516 study.  We are using our best
efforts to complete the requisite  reports including the hiring of new staff and
various  recognized expert  medical/regulatory  consultants,  but can provide no
assurance  as to whether  the outcome of this large data  collection  and filing
process  (approximately  750  patients,  treated more than 45,000 times) will be
favorable or unfavorable, specifically with respect to the FDA's perspective. We
plan  to use an  independent  contractor  to  file  the  NDA  electronically  to
facilitate  the review by the FDA.  Also,  we can  provide no guidance as to the
tentative  date at  which  the  compilation  and  filing  of such  data  will be
complete,  as  significant  factors are outside our control  including,  without
limitation,   the  ability  and   willingness   of  the   independent   clinical
investigators  to complete the  requisite  reports at an  acceptable  regulatory
standard,  the ability to collect  overseas  generated  data, and the ability of
Hollister-Stier  facilities (or the facilities of such other  manufacturer as we
may  retain  in  the  event  that  we do  not  come  to  definitive  terms  with
Hollister-Stier)  to interface  with our own New Brunswick  staff/facilities  to
meet the manufacturing regulatory standards.


                                       52


      The timing of the FDA review  process of the NDA is subject to the control
of the FDA and result in one of the  following  events;  1)  approval  to market
Ampligen(R)  for use in treating  ME/CFS  patients,  2) require  more  research,
development,  and clinical  work,  3) approval to market as well as conduct more
testing, or 4) reject our NDA application.  Given these variables, we are unable
to project when material net cash inflows are expected to commence from the sale
of Ampligen(R).

      Our  Amp  720  HIV  study  is a  treatment  using  a  Strategic  Treatment
Interruption ("STI"). The patients' antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as  mono-immunotherapy.  Patients, who have completed
at least nine months of Ampligen(R)  therapy,  were able to stay off HAART for a
total STI  duration  with a mean time of 29.0 weeks  whereas the control  group,
which was also taken off  HAART,  but not given  Ampligen(R),  had  earlier  HIV
rebound  with a mean  duration of 18.7  weeks.  Thus,  on  average,  Ampligen(R)
therapy  spared the  patients  excessive  exposure to HAART,  with its  inherent
toxicities, for more than 11 weeks.

      41 HIV patients have already  participated in this 64 week study. The rate
of enrollment  depends on patient  availability  and on other  products being in
clinical  trials for the  treatment  of HIV,  causing  competition  for the same
patient  population.  At  present,  more  than  18 FDA  approved  drugs  for HIV
treatment  competing for available  patients.  The length,  and subsequently the
expense of these studies,  will also be determined by an analysis of the interim
data,  which  will  determine  when  completion  of  the  ongoing  Phase  IIb is
appropriate  and whether a Phase III trial will be  conducted  or not. In case a
Phase  III  study is  required,  the FDA  might  require  a  patient  population
exceeding  the current one which will  influence the cost and time of the trial.
Accordingly,  the number of  "unknowns"  is  sufficiently  great to be unable to
predict  when,  or  whether,  we may  obtain  revenues  from  our HIV  treatment
indications.

      With the threat of an avian influenza pandemic rising and health officials
warning that the virus could develop  resistance to current flu treatments,  the
pursuit of a cost-effective and complementary  treatment to existing  antivirals
and vaccines has become  critical.  This combination may permit the use of lower
dosages and fewer injections of the antivirals and vaccines used to combat avian
flu,  thereby  decreasing the cost of both  immunization  programs and treatment
programs for the full-blown disease.

      In  antimicrobial  (antibacterial)  therapy,  which  is  the  best-studied
clinical  model,   synergistic   drug   combinations   may  result  in  curative
conditions/outcomes,  often not observed  when the single drugs are given alone.
In the case of avian influenza where global drug supplies are  presumptively  in
very  limited  supply  relative  to  potential  needs,  therapeutic  synergistic
combinations  could not only affect the disease outcome,  but also the number of
individuals able to access therapies.


                                       53


      In  a  recently  reported  study  from  a  vaccine  group  in  Japan,  the
incorporation of poly I: poly C (dsRNA) into a nasal  administration of a killed
influenza A preparation  converted a poorly  immunogenic  response into a highly
efficacious  vaccine in  protection  of mice from  lethal  infection  from human
influenza A. Ampligen(R) is a dsRNA which currently is undergoing testing in the
animal model.

      Recently, at the fourth annual Biodefense Research Meeting of the American
Society of  Microbiology  held in  Washington,  D.C.,  we  presented  results of
laboratory  testing  that  showed  our two  investigational  immunotherapeutics,
Ampligen(R) and Alferon(R),  are potentially  useful against H5N1, or avian flu,
virus.  The pre-clinical  research  indicates that  Ampligen(R),  a specifically
configured  double-stranded RNA, can provide  cross-protection against avian flu
viral mutations as well as boost the  effectiveness of Tamiflu and Relenza,  the
only two drugs  formally  recognized  for  combating  bird flu, up to 100 times.
Other lab tests, in healthy human volunteers,  indicate that Alferon(R) LDO (Low
Dose Oral), a new delivery form of an anti-viral with prior regulatory  approval
for a category of sexually transmitted diseases, can stimulate genes that induce
the production of interferon and other immune compounds,  key building blocks in
the body's defense  system.  The studies were conducted in conjunction  with the
National Institute of Infectious Diseases of Japan.

      We have  recently  entered  into an  agreement  with  Defence  R&D Canada,
Suffield  ("DRDC  Suffield"),  an agency of the Canadian  Department of National
Defence,  to evaluate the  antiviral  efficacy of our  experimental  therapeutic
Ampligen(R) and Alferon(R) for protection  against human  respiratory  influenza
virus  infection in well validated  animal  models.  DRDC Suffield is conducting
research and development of new drugs that could potentially  become part of the
arsenal of existing  antiviral weapons to combat the bird flu. The initial study
will focus on the testing of potential drugs against the  respiratory  influenza
virus infection on a mouse-adapted strain of human influenza.  DRDC Suffield has
already conducted  extensive research in the use of liposome delivery technology
to enhance the antiviral activity of a closely-allied Ampligen(R) analogue, Poly
ICLC (an immunomodulating  dsRNA) which is very similar to Ampligen(R).  Results
suggest that ribo nucleic acid-based drugs have the ability to elicit protective
broad-spectrum  antiviral  immunity against various pathogenic  viruses.  Hence,
there is the potential for efficacy to be maintained against mutating strains of
an influenza virus.  Liposomes,  a carrier system for nucleic  acid-based drugs,
have  shown an  ability  to protect  these  drugs  against in vivo  degradation,
delivering  them to  intracellular  sites of  infection,  thereby  reducing  any
toxicity and  prolonging  their  therapeutic  effectiveness.  Protection  can be
afforded for 21 days with two doses of dsRNA. It is believed that in humans with
active flu infection, Tamiflu, given twice daily, may ameliorate symptoms.

      A  preclinical   study  was  initiated  in  June  2005,  to  determine  if
Ampligen(R)  enhances the  effectiveness of different drug combinations on avian
influenza. The preclinical study suggests a new, and potentially pivotal role of
double-stranded  RNA  ("dsRNA")  therapeutics  in improving  the efficacy of the
present  standards in care in both  influenza  prevention and treatment of acute
disease.  The preclinical study is being conducted by research affiliates of the
National  Institutes  of Health at Utah State  University  to examine  potential
therapeutic synergies with different drug combinations.  The ongoing research is
comparing the relative protection conveyed by Tamiflu  (oseltamivir,  Roche) and
Relenza  (Zanamivir,  GlaxoSmithKline)  with Ampligen(R)  (dsRNA),  alone and in
combination,  against the avian flu virus (H5N1).  Cell destruction was measured
in vitro using  different  drug  combinations.  Both drugs,  given  alone,  were
effective  in  inhibiting  cell  destruction  by  avian  influenza,   but  viral
suppression with the combination was greater than either drug alone. The overall
assessment is that there was improvement in cell protection when Ampligen(R) was
combined with oseltamivir carboxylate (Tamiflu) and Zanamivir (Relenza). Further
immediate experimental tests are planned.


                                       54


      Recently,  Japanese researchers (Journal of Virology page 2910, 2005) have
found that dsRNAs increase the  effectiveness of influenza  vaccine by more than
300% and may also convey  "cross-protection  ability  against  variant  viruses"
(mutated  strains of influenza  virus).  In October  2005,  we signed a research
agreement with the National Institute of Infectious  Diseases,  in Tokyo, Japan.
The collaboration,  by Hideki Hasegawa,  M.D., Ph.D., Chief of the Laboratory of
Infectious   Disease  Pathology,   will  assess  our  experimental   therapeutic
Ampligen(R) as a co-administered  immunotherapeutic  to the Institution's  nasal
flu vaccine.

      In October  2005,  we also  engaged the Sage Group,  Inc.,  a health care,
technology  oriented,  strategy and  transaction  advisory firm, to assist us in
obtaining a strategic  alliance in Japan for the use of  Ampligen(R) in treating
Chronic  Fatigue  Syndrome  or CFS.  In the past year  leaders  in the  Japanese
medical  community have  established the Japanese Society of the Fatigue Science
and the Osaka City University Hospital opened the Fatigue Clinical Center as the
initial step in their Fatigue Research Project.

      A  clinical  study  has been  approved  by the  Clinical  Research  Ethics
Committee of the Kowloon West Cluster at the Princess  Margaret Hospital in Hong
Kong to evaluate the use of Alferon(R)  LDO (Low Dose Oral  Interferon  Alfa-N3,
Human Leukocyte Derived) in normal volunteers and/or asymptomatic  subjects with
exposure to a person known to have SARS.  This study completed the dosing of ten
patients during the fourth quarter 2005 and we expect to complete  analyzing the
results of this study in the coming months.

      A clinical  study to evaluate  the use of  Alferon(R)  LDO in HIV infected
volunteers was initiated during the second quarter 2005 in Philadelphia, PA. The
study  is  currently  being  conducted  at  two  sites,  Drexel  University  and
Philadelphia FIGHT, a comprehensive AIDS service organization  providing primary
care,  consumer  education,  advocacy and research on potential  treatments  and
vaccines.  The  study  is  designed  to  determine  whether  Alferon(R)  LDO can
resuscitate  the  broad-spectrum  antiviral  and  immunostimulatory  genes.  The
initial  patient  enrolled in this study in July 2005 and, as of December  2005,
seven patients have enrolled and completed  dosing.  We are currently  receiving
data from this study and we are in the process of analyzing  the  results.  This
trial methodology may have implications for treating other emerging viruses such
as avian influenza (bird flu).  Present  production methods for vaccines involve
the use of millions of chicken  eggs and would be slow to respond to an outbreak
according  to a recently  convened  World  Health  Organization  expert panel in
November 2004. Health officials are also concerned that bird flu could mutate to
cause  the  next  pandemic  and  render  present   vaccines  under   development
ineffective.

      In  September  2004,  we  commenced  a  clinical  trial  using  Alferon  N
Injection(R) to treat patients infected with the West Nile Virus. The infectious
Disease  section of New York Queens  Hospital and the Weill  Medical  College of
Cornell University are conducting this double-blinded, placebo controlled trial.
This study plans to enroll 60 patients as they become available.  As of March 1,
2006, nine patients have entered this study. The CDC reports that 2,744 cases of
West Nile Virus have been  reported in the US as of January 10, 2006,  including
105 deaths.


                                       55


      We have completed the transfer and  consolidation of our Rockville Quality
Assurance Lab and equipment  into our New  Brunswick  facility.  We believe this
newly consolidated lab will provide more efficiencies with regard to the quality
assurance needs for both Ampligen(R) and Alferon N Injection(R).

      In connection with settling various manufacturing  infractions  previously
noted by the FDA, Schering entered into a "Consent Decree" with the FDA whereby,
among other things,  it agreed to  discontinue  various  contract  (third party)
manufacturing  activities at various  facilities  including its San Juan, Puerto
Rico,  plant.   Ampligen(R)  (which  was  not  involved  in  any  of  the  cited
infractions)  was  produced  at this  Puerto  Rico  plant  from year  2000-2004.
Operating under  instructions  from the Consent Decree,  Schering has advised us
that it would no longer manufacture Ampligen(R) in this facility beyond 2004 and
would assist us in an orderly  transfer of said activities to other non Schering
facilities.

      On December 9, 2005, we executed a Supply  Agreement with  Hollister-Stier
Laboratories  LLC of Spokane,  Washington,  for the  contract  manufacturing  of
Ampligen(R)  for a five year term.  Pursuant to the agreement we will supply the
key raw materials and Hollister-Stier will formulate and bottle the Ampligen(R).
We paid  $100,000 as a deposit in order to initiate the  manufacturing  project.
This deposit was expended as research and  development in 2005. The  achievement
of the initial  objectives  described in the agreement,  in combination with our
polymer  production  facility under  construction  in New  Brunswick,  N.J., may
enable us to  manufacture  the raw materials for  approximately  10,000 doses of
Ampligen(R)   per  week.   We   executed  a   confidentiality   agreement   with
Hollister-Stier;  therefore,  we  commenced  the  transfer of our  manufacturing
technology  to  Hollister-Stier.  Currently,  Hollister-Stier  has completed two
pilot manufacturing runs of Ampligen(R) for stability testing.

      We have  identified  two other cGMP  production  facilities  in the United
States  capable  of  manufacturing  Ampligen(R).  Engagement  of either of these
facilities would provide back-up to  Hollister-Stier  and/or provide  additional
production  capacity if needed. We are reviewing proposals from these production
facilities and expect to act upon one or the other at the appropriate time.

General and Administrative Expenses

      General and  Administrative  ("G&A") expenses for the years ended December
31, 2005 and 2004 were  approximately  $5,389,000 and $6,164,000,  respectively.
The decrease in G&A expenses of $775,000 is  primarily  due to a non-cash  stock
compensation  charge  in 2004 of  $1,769,000  resulting  from  the  issuance  of
1,450,000  warrants to purchase common stock at $2.20 per share to Dr. Carter in
2003  that  vested  in  the  first  quarter  2004.  Higher   professional  fees,
specifically legal costs,  during 2005,  slightly offset this decrease in G&A as
we initiated legal  proceedings  seeking  injunction  relief and damages against
conspiratorial  group engaged in illegal  activities to take over Hemispherx and
enrich themselves at the expense of our stockholders.  Please see Item 3. "Legal
Proceedings" in Part I, above for more information.

Interest and Other Income


                                       56


      Interest and other  income for the years ended  December 31, 2005 and 2004
totaled $590,000 and $49,000,  respectively.  The increase in interest and other
income during the year can primarily be attributed to the maturing of marketable
securities during the 2005 period. All funds in excess of our immediate need are
invested in short-term high quality securities.

Interest Expense and Financing Costs

      Non-cash   financing  costs  and  interest  expenses  were   approximately
$3,121,000 for the year ended  December 31, 2005 versus  $5,674,000 for the same
period  a year  ago,  as  restated.  Non-cash  financing  costs  consist  of the
amortization  of  Original  Issue  Discounts  and   amortization  of  the  costs
associated  with  beneficial  conversion  features  of our  debentures  and  the
relative fair value of the warrants  relating to the  Debentures.  These charges
are reflected in the  Consolidated  Statements  of Operations  under the caption
"Financing  Costs." The main  reason for the  decrease  in  financing  costs and
interest  expense of $2,557,000 or 45% can be attributed to the aggregate  total
of these charges being reduced since 2004 due to decreased  amortization charges
as well as  lower  charges  related  to the  conversion  of  debentures  and the
principal amounts  decreasing.  Please see Note 8 in the consolidated  financial
statements contained herein for more details on these transactions.

Deemed Dividend

Deemed  dividend for the years ended  December 31, 2004 and 2005, was $4,031,000
and $0  respectively.  This  represents the fair value of the warrants issued to
our debenture holders as incentive to exercise prior warrant issuances.

Years Ended December 31, 2004 (as restated) vs. 2003 (as restated)

      During the year ended  December 31, 2004,  we 1)  materially  improved our
cash position,  2) completed the  acquisition of our production  facility in New
Brunswick,  New  Jersey,  as well as,  acquired  all of ISI's  rights  to market
Alferon(R) N, 3) completed drug dosing in our Phase III AMP 516 ME/CFS  clinical
trial and 4) continued our efforts to develop Ampligen(R)/Alferon(R) N. Our cash
position  improved as a result of placing  January and July 2004 6%  convertible
debentures  with an aggregate  maturity value of $6,000,000  (gross  proceeds of
$5,695,000)  and the August 2004  private  placement  with select  institutional
investors  of  approximately  3,617,000  shares of our common stock and warrants
producing $7,524,000 in gross proceeds. Completion of the drug dosing in the AMP
516  ME/CFS  clinical  trial in August  2004  allowed  us to start the next step
towards completing data collection and analysis.

Net loss applicable to common stockholders

      Non-cash charges  materially  affected our net losses applicable to common
stockholders  for the years ended  December  31, 2004 and 2003.  Our losses,  as
restated,  of $20,918,000 for the year ended December 31, 2004, include non-cash
financing  charges  of  $5,290,000,  non-cash  charges of  $2,000,000  for stock
compensation  expenses  and a $4,031,000  non-cash  charge due to the fair value
ascribed to warrant  issuances to our debenture holders as incentive to exercise
prior warrant issuances. The losses for the same period, as restated, in 2003 of
$15,215,000  included non-cash financing charges of $6,470,000.  This $5,703,000
increase in net loss  primarily  represents  an increase of $692,000 in research
and development  expenses, an increase of $1,610,000 in production/cost of goods
sold  and an  increase  of  $2,711,000  attributed  to the  warrants  issued  as
incentive to or  debenture  holders to exercise  prior  warrant  issuances.  The
non-cash  charge due to the fair value  ascribed to the warrant  issuance to our
debenture   holders  as  incentive  to  exercise  prior  warrant  issuances  was
$1,320,000 in 2003. The increase in our research and development  costs were the
result of 1) costs  incurred in the  development  of a more  efficient  bottling
manufacturing  process for Alferon N Injection(R),  2) vials abstracted from the
third lot of Alferon N  Injection(R)  inventory  for  research  and  development
purposes,  and 3) costs  associated  with  using  Alferon  N  Injection(R)  in a
clinical  trial to  treat  patients  infected  with the  West  Nile  Virus.  Our
production  cost/cost  of  goods  sold  increased  due to 1)  higher  Alferon  N
Injection(R) sales, 2) costs related to preparing our New Brunswick, NJ facility
for the  installation of the lab now located in Rockville,  MD, and 3) expanding
production at our New Brunswick  facility to include  Ampligen(R)  raw material.
The $2,000,000 for stock compensation  expense primarily consisted of $1,769,000
resulting  from  warrants  issued to Dr. Carter in 2003 that vested in the first
quarter 2004.


                                       57


Revenues

      Revenues for the year ended December 31, 2004 were  $1,229,000 as compared
to revenues of $657,000 for the same period in 2003. Revenues for the year ended
December 31, 2004 from sales of Alferon(R) N totaled  $1,050,000 versus $509,000
for the  period  of March  11,  2003,  the date we  acquired  the  rights to the
Alferon(R) N business from ISI, through December 31, 2003. Sales of Alferon(R) N
are  anticipated  to increase as we have more  product  available  and intend to
expand our marketing/sales programs on an international basis. Revenues from our
ME/CFS cost recovery treatment programs principally underway in the U.S., Canada
and Europe were  $179,000 for the year ended  December 31, 2004 versus  $148,000
for the year ended December 31, 2003. These clinical treatment programs allow us
to  provide  Ampligen(R)  therapy  at our cost to  severely  debilitated  ME/CFS
patients.  Under this program the patients pay for the cost of Ampligen(R) doses
infused. These costs total approximately $7,200 for a 24-week treatment program.

      We  executed a  Memorandum  of  Understanding  (MOU) in January  2004 with
Astellas  Pharma  ("Astellas"),  formally  Fujisawa  Deutschland  GmbH,  a major
pharmaceutical  corporation,  granting  them an  exclusive  option for a limited
number  of months to enter a Sales and  Distribution  Agreement  with  exclusive
rights to market Ampligen(R) for ME/CFS in Germany, Austria and Switzerland. The
MOU  required us to file the full report on the results of our AMP 516  Clinical
Trial with  Astellas by May 31,  2004.  If the full  report was not  provided to
Astellas by May 31, 2004 and Astellas  did not wish to exercise  its option,  we
would  have  been  required  to refund  one half of the  400,000  Euro  fee.  We
submitted  our  initial  report to Astellas  on May 28,  2004 and  responded  to
subsequent inquiries for additional information. The option period ends 12 weeks
after the later of  Astellas's  review of the full  report on the results of our
Amp 516  clinical  trial  and  Astellas's  meeting  with  three  of the  trial's
principal   investigators.   We  received  an  initial  fee  of  400,000   Euros
(approximately  $497,000 US). If we did not provide them with the full report by
December 31, 2004 and Astellas did not wish to exercise its option,  we would be
required to refund the entire fee. On November 9, 2004, Astellas exercised their
right to  terminate  the MOU.  We did not agree on the process to be utilized in
certain European  Territories for obtaining  commercial approval for the sale of
Ampligen(R) in the treatment of patients suffering from Chronic Fatigue Syndrome
(CFS).  Instead of a  centralized  procedure,  and in order to obtain an earlier
commercial  approval of  Ampligen(R) in Europe,  we have  determined to follow a
decentralized  filing procedure which was not anticipated in the MOU. We believe
that  it  now  is in the  best  interest  of  our  stockholders  to  potentially
accelerate  entry into  selected  European  markets  whereas  the  original  MOU
specified a centralized registration procedure. Pursuant to the agreement of the
parties we  refunded  200,000  Euros  ($248,000  USD) to  Astellas in the fourth
quarter  2004. We recorded the  remaining  200,000 Euros  ($271,000 and $241,000
USD) as an accrued liability as of December 31, 2004 and 2005, respectively.


                                       58


Production costs/cost of goods sold

      Production  costs  for the year  ended  December  31,  2004 and 2003  were
$2,112,000  and  $502,000,   respectively.  These  costs  reflect  approximately
$470,000  for the cost of sales of  Alferon N  Injection(R)  for the year  ended
December 31, 2004. In addition,  costs of sales for Alferon N  Injection(R)  for
the period  March 11, 2003  (acquisition  date of  inventory  from ISI)  through
December 31, 2003 amounted to $240,000.  The remaining  production costs in 2004
represented  expenditures  associated with preparing the New Brunswick  facility
for the  installation  of the lab  previously  located in Rockville,  MD and for
further  production of Alferon N Injection(R) and Ampligen(R) raw materials.  In
August 2004, we released most of the second lot of product (approximately 13,000
vials) to Abbott  laboratories  for bottling and realized  approximately  12,000
vials of Alferon(R)  N. Some 3,000 of the  remaining  vials within this lot were
held back to be utilized in the  development of a more  compatible vial size for
manufacturing  of Alferon N  Injection(R).  Our production  and quality  control
personnel  in our New  Brunswick,  NJ facility  are  involved  in the  extensive
process of manufacturing and validation required by the FDA.

Research and Development costs

      Overall research and development  direct costs for the year ended December
31, 2004 were $3,842,000 as compared to $3,150,000 during the same period a year
earlier.  These costs  primarily  reflect the direct costs  associated  with our
effort to  develop  our lead  product,  Ampligen(R),  as a therapy  in  treating
chronic  diseases  and cancers as well as  on-going  clinical  trials  involving
patients  with HIV.  The  primary  reasons  for the  increase  in  research  and
development  costs of $692,000  for the year ended  December 31, 2004 versus the
same  period  a  year  ago  were  primarily  due  to 1)  costs  incurred  in the
development of a more  efficient  bottling  manufacturing  process for Alferon N
Injection(R),  2) vials  abstracted from the third lot of Alferon N Injection(R)
inventory for research and development  purposes,  and 3) costs  associated with
using Alferon N Injection(R) in a clinical trial to treat patients infected with
the West Nile Virus.

      In 2004 we completed the double-blind  segment of our AMP 516 ME/CFS Phase
III clinical trial for use of  Ampligen(R) in the treatment of ME/CFS.  Clinical
data on the primary endpoint  exercise  treadmill  duration was presented at the
17th  International  Conference on Anti-viral  Research in Tucson,  AZ on May 3,
2004. The data showed that patients receiving  Ampligen(R) for 40 weeks improved
exercise  treadmill  performance  by a medically and  statistically  significant
amount compared to the Placebo group. New data was presented at the Interscience
Conference on  Antimicrobial  Agents and  Chemotherapy  on increases in exercise
capacity with  Ampligen(R)  and Placebo which were  correlated  with an improved
ability to utilize oxygen,  so called,  maximum oxygen  consumption or (VO2max).
VO2max has been previously shown by others to be decreased with individuals with
CFS. An  abnormal  exercise  stress  test,  including  a low VO2max,  could help
qualify CFS patients for disability under Social Security  Administration rules.
Additional  data on subset  analyses  showed  that both  Stratification  cohorts
(those with baseline exercise  treadmill duration greater than or less than nine
minutes) improved exercise capacity by over 6.5%, an amount considered medically
significant in other chronic diseases.


                                       59


      Ampligen(R)  is in two  Phase  IIb  studies  for the  treatment  of HIV to
overcome  multi-drug  resistance,  virus mutation and toxicity  associated  with
current HAART therapies. One study, the AMP-719, is a Salvage Therapy, conducted
in the U.S. and evaluating the potential  synergistic efficacy of Ampligen(R) in
multi-drug resistant HIV patients for immune enhancement.  The second study, the
AMP-720,  is a clinical  trial  designed to evaluate  the effect of  Ampligen(R)
under  Strategic  Treatment  Intervention  and is  also  conducted  in the  U.S.
Enrollment  in the AMP 719 study is presently on hold as we focus our efforts on
the AMP 720 study.

ME/CFS

      Over 230  patients  have  participated  in our ME/CFS  Phase III  clinical
trial. In August 2004, the remaining  patients completed drug dosing in the open
label segment (Stage II) of this Phase III protocol. We completed the randomized
placebo  controlled  phase  (Stage I) of this  study in  February  2004 and have
started  final data  collection  for the data  analysis.  This process  includes
validation and quality  assurance and should be completed by early 2005. As with
any experimental  drug being tested for use in treating human diseases,  the FDA
must approve the testing and clinical  protocols  employed and must render their
decision based on the safety and efficacy of the drug being tested. Historically
this is a long and costly process.  Our ME/CFS AMP 516 clinical study is a Phase
III study, which based on favorable  results,  will serve as the basis for us to
file a new drug  application  with the FDA.  The FDA review  process  could take
18-24 months and result in one of the  following  events;  1) approval to market
Ampligen(R)  for use in treating  ME/CFS  patients,  2) required more  research,
development,  and clinical  work,  3) approval to market as well as conduct more
testing,  or 4)reject our application.  Given these variables,  we are unable to
project when material net cash inflows are expected to commence from the sale of
Ampligen(R).

HIV

      The  Amp  720  HIV  study  is a  treatment  using  a  Strategic  Treatment
Interruption  (STI). The patients'  antiviral HAART regimens are interrupted and
Ampligen(R) is substituted as mono-immunotherapy. Ampligen(R) is an experimental
immunotherapeutic  designed  to display  both  antiviral  and  immune  enhancing
characteristics.  Prolonged use of Highly Active Antiretroviral  Therapy (HAART)
has been associated with long-term,  potentially fatal, toxicities. The clinical
study  AMP  720  is  designed  to  address  these  issues  by   evaluating   the
administration of our lead experimental  agent,  Ampligen(R),  a double stranded
RNA drug acting potentially both as an immunomodulator and antiviral.  Patients,
who have  completed at least nine months of  Ampligen(R)  therapy,  were able to
stay off HAART for a total STI duration  with a mean time of 29.0 weeks  whereas
the control group,  which was also taken off HAART,  but not given  Ampligen(R),
had earlier HIV rebound with a mean  duration of 18.7 weeks.  Thus,  on average,
Ampligen(R)  therapy spared the patients  excessive  exposure to HAART, with its
inherent toxicities,  for more than 11 weeks. As more patients are enrolled, the
related clinical costs will continue to increase with some offset to our overall
expenses  due to the  diminishing  cost  of the  ME/CFS  clinical  trial.  It is
difficult  to estimate  the  duration or  projected  costs of these two clinical
trials  due to the  many  variables  involved,  i.e.:  patient  drop  out  rate,
recruitment  of clinical  investigators,  etc. The length of the study and costs
related to our clinical trials cannot be determined at this time as such will be
materially  influenced  by (a) the number of  clinical  investigators  needed to
recruit and treat the required  number of  patients,  (b) the rate of accrual of
patients and (c) the retention of patients in the studies and their adherence to
the  study  protocol  requirements.   Under  optimal  conditions,  the  cost  of
completing the studies could be approximately $2.0 to $3.0 million.  The rate of
enrollment  depends  on  patient  availability  and on other  products  being in
clinical  trials for the treatment of HIV, as there is competition  for the same
patient  population.  At  present,  more  than  18 FDA  approved  drugs  for HIV
treatment  compete for available  patients.  The length,  and  subsequently  the
expense of these studies,  will also be determined by an analysis of the interim
data,  which  will  determine  when  completion  of  the  ongoing  Phase  IIb is
appropriate  and whether a Phase III trial be  conducted or not. In case a Phase
III study is required;  the FDA might require a patient population exceeding the
current one which will  influence  the cost and time of the trial.  Accordingly,
the number of "unknowns" is sufficiently  great to be unable to predict when, or
whether,  we will  complete  this  trial  and/or  obtain  revenues  from our HIV
treatment indications.


                                       60


      In  September,  2004  we  commenced  a  clinical  trial  using  Alferon  N
Injection(R) to treat patients infected with the West Nile Virus. The infectious
Disease  section of New York Queens  Hospital and the Weill  Medical  College of
Cornell  University will be conducting this  double-blinded,  placebo controlled
trial.  During 2004,  over 2,000 human cases of West Nile Virus were reported in
40 states.

Manufacturing

      In order to  obtain  Ampligen(R)  raw  materials  of higher  quality  (GMP
certified)  and  on  a  more  regular  production  basis,  we  have  implemented
consolidation  and transfer of relevant  manufacturing  operations  into our New
Brunswick, New Jersey facility. This consolidation and transfer of manufacturing
operations has been implemented as a recent  inspection of the Ribotech facility
in South Africa,  our previous supplier of Ampligen(R) raw materials,  indicated
that it did not,  at  present,  meet the  necessary  GMP  standards  for a fully
certified   commercial  process.  The  transfer  of  Ampligen(R)  raw  materials
manufacture to our own facilities,  while having obvious advantages with respect
to  regulatory  compliance  (other  parts of the  43,000 sq.  ft.  wholly  owned
facility are already in  compliance  for  Alferon(R) N  manufacture),  may delay
certain  steps in the  commercialization  process,  specifically  a targeted NDA
filing.

      In connection with settling various manufacturing  infractions  previously
noted by the FDA, Schering entered into a "Consent Decree" with the FDA whereby,
among other things,  it agreed to  discontinue  various  contract  (third party)
manufacturing  activities at various  facilities  including its San Juan, Puerto
Rico,  plant.   Ampligen(R)  (which  was  not  involved  in  any  of  the  cited
infractions)  was  produced  at this  Puerto  Rico  plant  from year  2000-2004.
Operating  under  instructions  from the Consent  Decree,  Schering has recently
advised us that it would no longer  manufacture  Ampligen(R) in this facility at
the end of the  applicable  term (which is 4th quarter 2004) and would assist us
in an orderly transfer of said activities to other non Schering  facilities.  On
December  9,  2005,  we  executed  a  Supply   Agreement  with   Hollister-Stier
Laboratories LLC of Spokane,  Washington  ("Hollister-Stier"),  for the contract
manufacturing of Ampligen(R) for a five year term.  Pursuant to the agreement we
will supply the key raw materials and Hollister-Stier  will formulate and bottle
the Ampligen(R). In November 2005, we paid a $100,000 deposit upon executing the
agreement  in order to initiate  the  manufacturing  project.  We recorded  this
payment as a research  and  development  cost in 2005.  The  achievement  of the
initial objectives  described in the agreement,  in combination with our polymer
production facility under construction in New Brunswick,  N.J., may enable us to
manufacture the raw materials for approximately  10,000 doses of Ampligen(R) per
week. We executed a confidentiality  agreement with Hollister-Stier;  therefore,
we commenced the transfer of our  manufacturing  technology to  Hollister-Stier.
Currently,  Hollister-Stier  has  completed  two  pilot  manufacturing  runs  of
Ampligen(R) for stability testing.


                                       61


      We have  identified  two other cGMP  production  facilities  in the United
States  capable  of  manufacturing  Ampligen(R).  Engagement  of either of these
facilities would provide back-up to  Hollister-Stier  and/or provide  additional
production  capacity if needed. We are reviewing proposals from these production
facilities and expect to act upon one or the other at the appropriate time.

      The purified drug  concentrate  utilized in the  formulation  of Alferon N
Injection(R)  is  manufactured  in our New  Brunswick,  New Jersey  facility and
Alferon N  Injection(R)  was  formulated  and packaged at a production  facility
formerly  owned and operated by Abbott  Laboratories  located in Kansas.  Abbott
Laboratories has sold the facility to Hospira.  Hospira  recently  completed the
production  of 11,590  vials.  Hospira is ceasing the labeling and  packaging of
Alferon N  Injection(R)  as they are  seeking  larger  production  runs for cost
efficiency  purposes.  We have identified two manufacturers  and, on February 8,
2006, we executed a  Manufacturing  and Safety  Agreement  with  Hyaluron,  Inc.
("Hyaluron") of Burlington,  Massachusetts,  for the formulation,  packaging and
labeling of Alferon N  Injection(R).  Pursuant to the Agreement,  we will supply
raw materials in sufficient  quantity and provide any pertinent  information  to
the project.

General and Administrative Expenses

      General and  Administrative  ("G&A")  expenses for the year ended December
31, 2004 and 2003 were  approximately  $6,164,000 and $4,257,000,  respectively.
The increase in G&A expenses of  $1,907,000  during this period is primarily due
to non-cash charges of $2,000,000 for stock compensation expenses in 2004. These
stock  compensation  charges  consisted of  $1,769,000  resulting  from warrants
issued to Dr.  Carter in 2003 that  vested in 2004 and  directors'  fees paid in
2004 of  $231,000.  The  warrants  noted above  vested upon the second ISI asset
closing which occurred on March 17, 2004. In addition,  investment  banking fees
relating to assistance in financing  matters  increased in 2004 by approximately
$124,000. These increases were offset by a decrease in professional fees in 2004
of  approximately  $191,000 as compared to a year earlier.  These  services fees
related to the acquisition of ISI.

Impairment loss

      During the year ended December 31, 2004, we recorded a non-cash  charge of
$373,000 with respect to our investment in Chronix.  This impairment reduces our
carrying value to reflect a permanent decline in Chronix's market value based on
its then proposed investment offerings.

Other Income/Expense

      Interest  and other  income for the year ended  December 31, 2004 and 2003
totaled $49,000 and $80,000,  respectively. All funds in excess of our immediate
need are invested in short-term high quality securities.

Interest Expense and Financing Costs


                                       62


      Interest expense and financing costs, as restated, were $5,674,000 for the
year ended  December  31,  2004 versus  $6,723,000  for the same period in 2003.
Non-cash financing costs consist of the amortization of Original Issue Discounts
and the amortization costs associated with beneficial conversion features of our
debentures and the fair value of the warrants relating to the Debentures.  These
charges are reflected in the  Consolidated  Statements  of Operations  under the
caption "Financing Costs."

Deemed Dividend

Deemed  dividend for the years ended  December 31, 2003 and 2004, was $1,320,000
and  $4,031,000,  respectively.  This  represents the fair value of the warrants
issued  to  our  debenture  holders  as  incentive  to  exercise  prior  warrant
issuances.

Liquidity and Capital Resources

      Cash used in operating activities for the year ended December 31, 2005 was
$7,231,000.  Cash provided by financing  activities  for the year ended December
31, 2005 amounted to $8,029,000,  primarily from the sale of common stock. As of
April 30, 2006, we had  approximately  $23,900,000 in cash and cash  equivalents
and short-term investments, or an increase of $7,630,000 from December 31, 2005.
These  funds  should  be  sufficient  to meet our  operating  cash  requirements
including debt service for the next 18 months.

      On April 12, 2006 we entered into a common stock  purchase  agreement with
Fusion  Capital.  Fusion Capital has agreed to purchase up to $50,000,000 of our
common stock over a period of approximately 25 months.  Refer to the "Financing;
Equity  Financing"  section below for more details on this  agreement.  Over the
long term, we may need to raise  additional funds through  additional  equity or
debt financing or from other sources in order to complete the necessary clinical
trials and the regulatory  approval processes  including the  commercializing of
Ampligen(R)  products.  There can be no assurances  that we will raise  adequate
funds from these or other sources,  which may have a material  adverse effect on
our  ability to develop  our  products.  Any  additional  funding  may result in
significant  dilution and could involve the issuance of securities  with rights,
which are senior to those of existing stockholders.  We may also need additional
funding earlier than anticipated,  and our cash  requirements,  in general,  may
vary materially from those now planned,  for reasons including,  but not limited
to,  changes  in  our  research  and  development  programs,   clinical  trials,
competitive and technological  advances, the regulatory process, and higher than
anticipated  expenses and lower than  anticipated  revenues  from certain of our
clinical trials for which cost recovery from participants has been approved.

FINANCING

Debentures

      As of May 24, 2006,  the investors have received  installment  payments of
$2,388,888 and have converted an aggregate  $14,503,023 principal amount of debt
from the debentures as noted below:

      Pursuant to the terms and conditions of all of the outstanding Debentures,
we have  pledged all of our assets,  other than our  intellectual  property,  as
collateral, and we are subject to comply with certain financial covenants.

      In connection with the Debenture  agreements,  we have outstanding letters
of credit of $1,000,000 as additional collateral.

      We  failed  to timely  file our 2005  Annual  Report on Form 10-K with the
Securities and Exchange Commission pursuant to the 1934 Act, and therefore, were
in violation of our covenant within our debenture  agreements to timely file. We
obtained waiver letters from the debenture holders regarding the failure to meet
this covenant.

See Note 8 of the  consolidated  financial  statements for a full description of
all Debentures.

Equity Financing

On April 12, 2006, we entered into a common stock purchase  agreement (the "2006
Purchase  Agreement")  with  Fusion  Capital  Fund II, LLC  ("Fusion  Capital"),
pursuant to which  Fusion  Capital  has agreed,  under  certain  conditions,  to
purchase on each  trading day $100,000 of our common stock up to an aggregate of
$50.0 million over a period of  approximately  25 months as described  below. We
have the right to suspend such purchases or terminate the agreement at any time.
The purchase  price of the shares of common stock will be equal to a price based
upon the future market price of the common stock.  Fusion  Capital does not have
the right or the obligation to purchase  shares of our common stock in the event
that the price of our common stock is less than $1.00.

The purchase  price per share will be equal to the lesser of (i) the lowest sale
price of our common stock on the purchase date; or (ii) the average of the three
lowest  closing sale prices of our common  stock  during the twelve  consecutive
trading days prior to the date of a purchase by Fusion Capital.

The purchase  price will be adjusted for any  reorganization,  recapitalization,
non-cash dividend, stock split, or other similar transaction. Fusion Capital may
not  purchase  shares of our  common  stock  under  the  common  stock  purchase
agreement if it, together with its affiliates,  would beneficially own more than
9.9% of our  common  stock  outstanding  at the time of the  purchase  by Fusion
Capital.  Fusion Capital has the right at any time to sell any shares  purchased
under  the 2006  Purchase  Agreement  which  would  allow  it to avoid  the 9.9%
limitation.  Without prior stockholder approval, we do not have the right or the
obligation  under the  Agreement  to sell shares to Fusion  Capital in excess of
12,386,723  shares  (i.e.  19.99% of the  61,964,598  outstanding  shares of our
common stock on April 12, 2006, the date the 2006 Purchase Agreement)  inclusive
of the commitment shares (discussed  below). We would have to average a purchase
price of  approximately  $4.28 per share to receive the full $50.0 million under
the common stock purchase agreement if we do not receive stockholder approval.


                                       64


We also  have the  right to  increase  the  daily  purchase  amount at any time,
provided  however,  we may not increase the daily purchase amount above $100,000
unless our stock  price is above  $1.90 per share for five  consecutive  trading
days.  Specifically,  for every $0.10  increase in  Threshold  Price (as defined
below) above $1.90,  we have the right to increase the daily purchase  amount by
up to an additional  $10,000.  The "Threshold Price" is the lowest sale price of
our common stock during the five trading days  immediately  preceding our notice
to Fusion Capital to increase the daily purchase  amount.  If at any time during
any trading day the sale price of our common stock is below the Threshold Price,
the applicable increase in the daily purchase amount will be void.

In addition to the daily purchase amount, we may elect to require Fusion Capital
to purchase on any single trading day the following:

      o     $250,000  if our  common  stock  trades at $1.50 or better  for five
            trading days.

      o     $500,000  if our  common  stock  trades at $3.00 or better  for five
            trading days.

      o     $1,000,000  if our common  stock  trades at $5.00 or better for five
            trading days.

      o     $2,000,000  if our common  stock  trades at $8.00 or better for five
            trading days.

The price at which such shares would be purchased  will be the lesser of (i) the
lowest  Sale Price on the  trading day that such  purchase  notice was  received
Fusion  Capital or (ii) the lowest  purchase price (as defined above) during the
previous  ten  trading  days  prior to the date that such  purchase  notice  was
received by Fusion Capital.

We have agreed to file a registration statement with the Securities and Exchange
Commission on or before June 30, 2006 covering the shares of our common stock to
be issued under the 2006 Purchase  Agreement and to keep it effective  until the
earlier  of the date that all  shares  are sold or can be sold  pursuant  to the
provisions  of  Rule  144(k)  under  the  Securities  Act.  While  there  are no
liquidated  damages  provisions,  as noted  below,  if we do not timely file the
registration  statement or keep it effective,  Fusion  Capital may terminate the
agreement.

Generally,  Fusion  Capital may  terminate the common stock  purchase  agreement
without  any  liability  or  payment  to us upon  the  occurrence  of any of the
following events of default:

o     our  failure  to  timely  file the  registration  statement  or,  once the
      registration  statement is declared  effective,  the  effectiveness of the
      registration  statement  lapses for any reason or is unavailable to Fusion
      Capital  for sale of our  common  stock and such  lapse or  unavailability
      continues for a period of 10 consecutive  trading days or for more than an
      aggregate of 30 trading days in any 365-day period;

o     suspension by our principal  market of our common stock from trading for a
      period of three consecutive trading days;

o     the de-listing of our common stock from the American Stock  Exchange,  our
      principal market,  provided our common stock is not immediately thereafter
      trading on the Nasdaq National  Market,  the Nasdaq SmallCap Market or the
      New York Stock Exchange or the OTC Bulleting Board;


                                       65


      o     the  transfer  agent's  failure  for five  trading  days to issue to
            Fusion  Capital  shares of our common stock which Fusion  Capital is
            entitled to under the 2006 Purchase Agreement;

      o     any  material  breach  of  the   representations  or  warranties  or
            covenants  contained in the 2006  Purchase  Agreement or any related
            agreements  which has or which could have a material  adverse affect
            on us subject to a cure period of 10 trading days;

      o     any  participation  or  threatened  participation  in  insolvency or
            bankruptcy proceedings by or against us;

      o     a material adverse change in our business,  properties,  operations,
            financial condition or results of operations; or

      o     the issuance of an aggregate of 12,386,723  shares to Fusion Capital
            under our agreement and we fail to obtain the requisite  stockholder
            approval.

We have the  unconditional  right at any time for any  reason to give  notice to
Fusion Capital  terminating  the 2006 Purchase  Agreement.  Such notice shall be
effective one trading day after Fusion Capital receives such notice.

Under the terms of 2006 Purchase Agreement,  Fusion Capital has received 321,751
shares  of our  common  stock as a partial  commitment  fee and is  entitled  to
receive  up  to  an  additional  321,751  commitment  shares.  These  additional
commitment  shares  will be  issued  in an amount  equal to the  product  of (x)
321,751 and (y) the Purchase Amount  Fraction.  The "Purchase  Amount  Fraction"
means a fraction,  the  numerator  of which is the  purchase  price at which the
shares are being  purchased by Fusion  Capital and the  denominator  of which is
$50,000,000.  Unless an event of default  occurs  these  shares  must be held by
Fusion  Capital until 25 months from the date of the 2006 Purchase  Agreement or
the date such  agreement is terminated  or in the event that certain  conditions
precedent  are not met such as the  registration  statement  not being  declared
effective by August 31, 2006.

      We anticipate using the proceeds from this financing for general corporate
purposes.

      On July 8, 2005, we entered into a common stock  purchase  agreement  (the
"2005 Agreement") with Fusion Capital,  pursuant to which Fusion Capital agreed,
under certain conditions,  to purchase on each trading day $40,000 of our common
stock,  unless our stock price  equals or exceeds  $2.00 in which case the daily
amount may be  increased  under  certain  conditions  as the price of the common
stock  increases,  up to an aggregate of $20.0 million over  approximately  a 25
month period,  subject to earlier termination at our discretion.  As of April 3,
2006, Fusion Capital  purchased  8,791,838 shares for gross proceeds of the full
$20.0 million.  Pursuant to the Agreement, in our discretion,  we could elect to
sell less common  stock to Fusion  Capital than the daily amount or increase the
daily amount as the market price of our stock  increases.  The purchase price of
the shares of common  stock was equal to a price based upon the market  price of
the common stock without any fixed discount to the market price.  Fusion Capital
did not have the right or the obligation to purchase  shares of our common stock
in the event that the price of the common stock is less than $1.00.  Pursuant to
our agreement  with Fusion  Capital,  on July 31, 2005, we registered for public
sale by Fusion Capital up to 10,795,597 shares of our common stock.


                                       66


      In connection  with entering into the above agreement with Fusion Capital,
in July  2005,  we issued  to Fusion  Capital  402,798  shares of common  stock.
392,798 of these shares represented 50% of the commitment fee due Fusion Capital
with the  remaining  10,000  shares issued as  reimbursement  for  expenses.  An
additional 392,799 shares, representing the remaining balance of the commitment,
are  issuable in  conjunction  with daily  purchases  of common  stock by Fusion
Capital.  These additional  commitment  shares were issued in an amount equal to
the product of (x) 392,799 and (y) the Purchase Amount  Fraction.  The "Purchase
Amount Fraction" means a fraction,  the numerator of which is the purchase price
at which the shares are being purchased by Fusion Capital and the denominator of
which is  $20,000,000.  As of April 5, 2006,  Fusion  Capital was issued 392,799
shares towards this remaining commitment fee.

New Accounting Pronouncements

      On  December  2004,  the FASB issued  Statement  of  Financial  Accounting
Standards No. 123 (Revised 2004),  "Share-Based Payment" ("SFAS 123R"). On April
14, 2005,  the Securities  and Exchange  Commission  issued an amendment to Rule
4-01 of  Regulation  S-X that allows  companies  to  implement  SFAS 123R at the
beginning of their next fiscal year,  instead of the next reporting  period that
begins after June 15, 2005 as originally  required.  Accordingly,  we will adopt
SFAS 123R effective January 1, 2006 using the "modified  prospective"  method in
which compensation cost is recognized  beginning with the effective date base on
(a) the requirements of SFAS 123R for all share-based payments granted after the
effective  date and (b) the  requirements  of SFAS 123 for all awards granted to
employees  prior to the effective date of SFAS 123R that remain  unvested on the
effective date. In addition,  we expect to continue to utilize the Black-Scholes
option-pricing   model,  which  is  an  acceptable  option  valuation  model  in
accordance  with SFAS 123R,  to estimate the value of stock  options  granted to
employees.


                                       67


      Beyond those restricted stock and stock option awards previously  granted,
we  cannot  predict  with  certainty  the  impact  of SFAS  123R  on its  future
consolidated  financial  statements  as the type and  amount of such  awards are
determined on an annual basis and encompass a potentially  wide range  depending
upon the  compensation  decisions made by the Human  Resources  Committee of our
Board of Directors.  SFAS 123R also  requires the benefits of tax  deductions in
excess  of  compensation  cost  recognized  in the  financial  statements  to be
reported  as a  financing  cash  flow,  rather  than an  operating  cash flow as
currently  required under  Statement of Financial  Accounting  Standards No. 95,
"Statement  of Cash  Flows"  ("SFAS  95").  This  requirement,  to the extent it
exists,  will decrease net operating  cash flows and increase net financing cash
flows in periods subsequent to adoption. We believe this pronouncement will have
a material impact on our consolidated financial statements.

      On March 29, 2005, the SEC issued Staff Accounting  Bulletin No. 107 ("SAB
107") which  expresses the view of the SEC Staff  regarding the  interaction  of
SFAS 123R and certain SEC rules and  regulations  and provides the staff's views
regarding the valuation of share-based payment arrangements. We believe that the
views  provided  in SAB  107 are  consistent  with  the  approach  taken  in the
valuation and accounting  associated  with  share-based  compensation  issued in
prior periods as well as those issued during 2005.

      In June 2005, the FASB's  Emerging  Issues Task Force ("EITF") issued EITF
Issue No. 05-02 "The Meaning of  "Conventional  Convertible  Debt Instrument" in
EITF Issue 00-19 "Accounting for Derivative  Financial  Instruments  Indexed to,
and Potentially Settled in, A Company's Own Stock",  which retains the exception
in paragraph 4 of EITF Issue No. 00-19 for conventional debt instruments.  Those
instruments in which the holder has an option to convert the  instrument  into a
fixed  number  of shares  (or a  corresponding  amount  of cash at the  issuer's
discretion)  and its ability to  exercise  the option is based on either (a) the
passage of time or (b) a contingent event,  should be considered  "conventional"
for purposes of applying that  exception.  The consensus  should be applied on a
prospective  basis  for new or  modified  instruments  starting  from the  third
quarter of 2005.  The adoption of EITF No. 05-02 did not have a material  effect
on our consolidated financial statements or results of operations.

      In November 2005, FASB issued FSP FAS 115-1 and FAS 124-1, "The Meaning of
Other-Than-Temporary  Impairment  and Its  Application  to Certain  Investments"
("FSP FAS 115-1"),  which provides  guidance on determining  when investments in
certain  debt  and  equity  securities  are  considered  impaired,   whether  an
impairment is  other-than-temporary,  and on measuring such impairment loss. FSP
FAS 115-1 also includes accounting  considerations subsequent to the recognition
of an  other-than-temporary  impairment and requires certain  disclosures  about
unrealized  losses  that  have  not  been  recognized  as   other-than-temporary
impairments.  FSP FAS 115-1 is  required  to be  applied  to  reporting  periods
beginning after December 15, 2005. We are required to adopt FSP FAS 115-1 in the
first quarter of 2006. We do not expect the adoption of this statement to have a
material  impact  on  our  consolidated   results  of  operations  or  financial
condition.

      In November  2004,  the FASB issued  SFAS No. 151,  "Inventory  Costs - An
amendment of ARB No. 43,  Chapter 4" ("SFAS No.  151").  SFAS No. 151 amends the
guidance in Accounting Research Bulletin No. 43, Chapter 4, "Inventory Pricing,"
to  clarify  the  accounting  for  abnormal  amounts of idle  facility  expense,
freight, handling costs, and wasted material (spoilage).  Additionally, SFAS No.
151 requires that the  allocation of fixed  production  overheads to the cost of
conversion be based on the normal  capacity of the production  facilities.  SFAS
No.  151 is  required  to be  adopted  in the  first  quarter  of 2006.  We have
determined  that the adoption of SFAS No. 151 will not have a material impact on
the consolidated financial statements.


                                       68


      In  December  2004,  the FASB issued  Statement  of  Financial  Accounting
Standards No. 153 ("SFAS 153"),  "Exchanges of Non-monetary  Assets-an amendment
of APB Opinion No. 29." SFAS 152  addresses  the  measurement  of  exchanges  of
non-monetary assets. It eliminates the exception from fair value measurement for
non-monetary  exchanges of similar  productive  assets in paragraph 21(b) of APB
Opinion No. 29 "Accounting for Non-monetary  Transactions"  and replaces it with
an exception for exchanges that do not have commercial substance. A non-monetary
exchange  has  commercial  substance  if the future cash flows of the entity are
expected to change  significantly  as a result of the  exchange.  As required by
SFAS 153, we adopted this new  accounting  standard  effective July 1, 2005. The
adoption of SFAS 153 did not have a material impact on our financial statements.

      In May 2005,  the FASB issued SFAS No. 154,  Accounting  Changes and Error
Corrections.  SFAS No. 154 establishes retrospective application as the required
method for reporting a change in accounting principle in the absence of explicit
transition requirements specific to the newly adopted accounting principle. SFAS
No. 154 also provides guidance for determining whether retrospective application
is impractical. SFAS No. 154 is effective for accounting changes and corrections
of errors made in fiscal years  beginning  after  December  15, 2005.  We do not
expect  that the  adoption  of SFAS No. 154 will have a  material  impact on its
results of operations or financial position.

Disclosure About Off-Balance Sheet Arrangements

      Prior to our annual meeting of  stockholders  in September  2003, we had a
limited  number of shares of Common Stock  authorized but not issued or reserved
for  issuance  upon  conversion  or  exercise  of  outstanding  convertible  and
exercisable  securities such as debentures,  options and warrants.  Prior to the
meeting,  to permit consummation of the sale of the July 2003 Debentures and the
related  warrants,  Dr. Carter agreed that he would not exercise his warrants or
options unless and until our stockholders  approve an increase in our authorized
shares of common stock. For Dr. Carter's waiver of his right to exercise certain
options and warrants prior to approval of the increase in our authorized shares,
we have agreed to compensate Dr. Carter and issued Dr. Carter 1,450,000 warrants
to  purchase  common  stock at $2.20 per share in 2003 that  vested in the first
quarter 2004 upon the second ISI asset closing.

Critical Accounting Policies

      Financial  Reporting  Release No. 60 requires  all  companies to include a
discussion of critical accounting policies or methods used in the preparation of
financial statements.  Our significant  accounting policies are described in the
Notes to the  Consolidated  Financial  Statements.  The  significant  accounting
policies  that we believe are most  critical to aid in fully  understanding  our
reported financial results are the following:

Revenue


                                       69


      Revenue  from  the  sale  of  Ampligen(R)  under  cost  recovery  clinical
treatment  protocols  approved by the FDA is  recognized  when the  treatment is
provided to the patient.

      Revenues  from the sale of  product  are  recognized  when the  product is
shipped,  as title is transferred to the customer.  We have no other  obligation
associated with our products once shipment has occurred.

Short-term Investments

      Investments  with  original  maturities of more than three months and less
than 12 months and marketable  equity  securities  are considered  available for
sale. The  investments  classified as available for sale include debt securities
and equity securities  carried at estimated fair value. The unrealized gains and
losses are recorded as a component of shareholders' equity.

Inventories

      We use the lower of first-in,  first-out ("FIFO") cost or market method of
accounting for inventory.

Patents and Trademarks

      Patents and trademarks are stated at cost  (primarily  legal fees) and are
amortized using the  straight-line  method over the estimated  useful life of 17
years We review our patents  and  trademark  rights  periodically  to  determine
whether  they have  continuing  value.  Such review  includes an analysis of the
patent  and  trademark's  ultimate  revenue  and  profitability   potential.  In
addition,  management's  review  addresses  whether each patent continues to fit
into our strategic business plans.

Convertible Securities with Beneficial Conversion Features

      The March  2003,  July  2003,  October  2003,  January  2004 and July 2004
Debenture  issuances  and related  embedded  conversion  features  and  warrants
issuances  were  accounted  for in  accordance  with EITF 98-5:  Accounting  for
convertible  securities  with  beneficial  conversion  features  or  contingency
adjustable conversion and with EITF No. 00-27:  Application of issue No. 98-5 to
certain convertible instruments. We determined the fair values to be ascribed to
detachable  warrants  issued  with  the  convertible  debentures  utilizing  the
Black-Scholes   method.   Discounts  derived  from  determining  the  beneficial
conversion  feature and fair value of the warrants  based on the  relative  fair
value of the proceeds are amortized to financing  costs over the remaining  life
of the debenture in accordance with the effective interest method of accounting.
The  unamortized  discount upon the  conversion of the debentures is expensed to
financing cost on a pro-rata basis.

Stock Based Compensation

      We follow  Statement of  Financial  Accounting  Standards  (SFAS) No. 123,
"Accounting  for  Stock-Based   Compensation."  We  chose  to  apply  Accounting
Principal Board Opinion 25 and related  interpretations  in accounting for stock
options granted to our employees.

      We provide pro forma  disclosures of  compensation  expense under the fair
market value method of SFAS No. 123, "Accounting for Stock-Based  Compensation,"
and SFAS No. 148,  "Accounting  for  Stock-Based  Compensation  - Transition and
Disclosure."


                                       70


      For stock  warrants or options  granted to  non-employees,  we measure the
fair value of the equity instruments  utilizing the Black-Scholes method if that
value is more reliably  measurable than the fair value of the  consideration  or
service received. We amortize such cost over the related period of service.

Concentration of Credit Risk

      Our policy is to limit the amount of credit  exposure to any one financial
institution and place investments with financial institutions evaluated as being
credit  worthy,  or in short-term  money  markets,  which are exposed to minimal
interest rate and credit risks. At and since December 31, 2005, we have had bank
deposits and  overnight  repurchase  agreements  that exceed  federally  insured
limits.

      Concentration  of credit  risk,  with respect to  receivables,  is limited
through  our credit  evaluation  process.  We do not require  collateral  on our
receivables.  Our receivables  consist principally of amounts due from wholesale
drug companies as of December 31, 2005.

Item 7A. Quantitative And Qualitative Disclosures About Market Risk

      We  had  approximately  $16,204,000  in  cash  and  cash  equivalents  and
short-term  investments  at December 31,  2005.  To the extent that our cash and
cash  equivalents  exceed our near term funding needs, we invest the excess cash
in three to twelve month high quality interest bearing financial instruments. We
employ established conservative policies and procedures to manage any risks with
respect to investment exposure.

      We have not  entered  into,  and do not  expect to enter  into,  financial
instruments for trading or hedging purposes.

ITEM 8. Financial Statements and Supplementary Data.

      The consolidated  balance sheets as of December 31, 2004 and 2005, and our
consolidated  statements  of  operations,  changes in  stockholders'  equity and
comprehensive loss and cash flows for each of the years in the three year period
ended  December  31,  2005,  together  with  the  report  of BDO  Seidman,  LLP,
independent  registered  public  accountants,  are  included  at the end of this
report.  Reference is made to the "Index to Financial  Statements  and Financial

Effectiveness of Control Procedures


                                       71


      As of December 31, 2005, the end of the period covered by this report,  we
carried out an evaluation  under the supervision and with the  participation  of
our management,  including our Chief  Executive  Officer and our Chief Financial
Officer,  of the  effectiveness  of the design and  operation of our  disclosure
controls and procedures as defined in Rules  13a-15(e) and  15d-15(e)promulgated
under the  Securities  Act of 1934,  as amended,  as of December 31,  2005.  Our
disclosure  controls and procedures are intended to ensure that the  information
we are  required to disclose  in the  reports  that we file or submit  under the
Securities  Exchange  Act of 1934 is (i)  recorded,  processed,  summarized  and
reported  within  the  time  periods   specified  in  the  Securities   Exchange
Commission's  rules and  forms  and (ii)  accumulated  and  communicated  to our
management,  including the Chief Executive Officer and Chief Financial  Officer,
as the principal executive and financial officers,  respectively, to allow final
decisions  regarding required  disclosures.  Because of the material  weaknesses
described in Management's  Report on Internal Control Over Financial  Reporting,
our management  has concluded  that, as of the end of the period covered by this
report,   our   disclosure   controls  and   procedures   were  not   effective.
Notwithstanding  the material  weaknesses  discussed  below,  our management has
concluded  that the  financial  statements  included  in this Form 10-K  present
fairly, in all material respects our financial  position,  results of operations
and cash flows for the periods  presented in conformity with generally  accepted
accounting principles.

Changes in Internal Control over Financial Reporting

      We made no changes in our internal control over financial reporting during
the last fiscal quarter that have materially affected,  or are reasonably likely
to materially affect, our internal control over financial  reporting (as defined
in Rules 13a-15(f) and 15d-15(f) under the Exchange Act).


                                       72


Management's Report on Internal Control Over Financial Reporting

      Our management is responsible for  establishing  and maintaining  adequate
internal  control  over  financial  reporting  as such term is  defined in Rules
13a-15(f) or 15d-15(f),  under the Exchange Act. Internal control over financial
reporting is a process  designed by, or under the  supervision of, our principal
executive  and  principal  financial  officers  and  affected  by our  Board  of
Directors,  management and other personnel,  and to provide reasonable assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial statements for external purposes in accordance with generally accepted
accounting  principles.  A company's  internal control over financial  reporting
includes those policies and  procedures  that (i) pertain to the  maintenance of
records  that,  in  reasonable   detail,   accurately  and  fairly  reflect  the
transactions  and  dispositions  of  the  assets  of  the  company;  (ii)provide
reasonable  assurance  that  transactions  are  recorded as  necessary to permit
preparation  of financial  statements  in  accordance  with  generally  accepted
accounting  principles,  and that receipts and  expenditures  of the company are
being made only in accordance with authorizations of management and directors of
the company;  and (iii) provide  reasonable  assurance  regarding  prevention or
timely  detection  of  unauthorized  acquisition,  use,  or  disposition  of the
company's assets that could have a material effect on its financial statements.

      Because of its  inherent  limitations,  internal  control  over  financial
reporting  may not prevent or detect  misstatements.  Also,  projections  of any
evaluation of  effectiveness to future periods are subject to risk that controls
may become  inadequate  because of changes in conditions,  or that the degree of
compliance with the policies or procedures may deteriorate.


                                       73


      Management  has assessed the  effectiveness  of our internal  control over
financial  reporting  as of  December  31,  2005.  In  making  this  assessment,
management  used the  criteria  set forth in the  framework  established  by the
Committee  of  Sponsoring  Organizations  of the  Treadway  Commission  Internal
Control--Integrated Framework, (COSO). Based on this assessment,  management has
identified the following material weaknesses as of December 31, 2005. A material
weakness is a control deficiency,  or combination of control deficiencies,  that
results in more than a remote  likelihood  that a material  misstatement  of the
annual or interim financial statements will not be prevented or detected.

      1.    Financial  Statement  Close  and  Reporting  Process  - We  did  not
            maintain effective  controls over the financial  statement close and
            reporting  process  because we lacked a complement of personnel able
            to devote sufficient time and adequate financial reporting expertise
            commensurate with quarterly and year-end  financial  statement close
            requirements,  which include the financial statement preparation and
            disclosures. Additionally, we had inadequate policies and procedures
            providing  for a  detailed  comprehensive  review of the  underlying
            information  supporting  the  amounts  including  in our  annual and
            interim consolidation financial statements and disclosures. The lack
            of  personnel  resources  with  specific  technical  accounting  and
            financial accounting expertise  contributed to the material weakness
            discussed in number two below.

      2.    We did not maintain effective controls over the initial recording of
            our  convertible  debentures  that contained  beneficial  conversion
            features  (including  incorrect recording of investment banking fees
            incurred and subsequent  conversion price resets) and the accounting
            for warrants and options issued to non-employees. Our interpretation
            and application of EITF No. 00-27, FASB Statement 133, EITF 98-5 and
            EITF 00-19 was not  correct at the time the  convertible  debentures
            were  initially   recorded   (2003  through  July  2004),   and  our
            interpretation  and  application  of FASB  statement No. 123 was not
            correct  in  recording  certain  warrant  and  option  issuances  to
            non-employees.   These   control   deficiencies   resulted   in  the
            restatement  of the  2004  and 2003  annual  consolidated  financial
            statements  as  well  as  to  the  unaudited   consolidated  interim
            financial statements for each of the three years in the period ended
            December 31, 2005.

      Because of these material weaknesses, management has concluded that we did
not maintain effective internal control over financial  reporting as of December
31,  2005,  based on the  criteria  set forth in  "Internal  Control--Integrated
Framework" issued by the COSO.

      Management's  assessment of the effectiveness of our internal control over
financial reporting as of December 31, 2005 has been audited by BDO Seidman LLP,
an  independent  registered  public  accounting  firm, as stated in their report
which appears herein.

Plans for Remediation of Material Weaknesses

      Convertible debenture  arrangements are inherently complicated and are not
classified as normal recurring transactions. The root of the referenced non-cash
restatements  above stems from our entering into complex  convertible  debenture
arrangements  during the periods from March 2003 through July 2004.  We have not
entered into any debenture arrangements  thereafter.  We have taken, and plan to
take,   additional  steps  to  remediate  the  material  weaknesses   concerning
convertible  debentures that contained beneficial conversion features (including
incorrect   recording  of  investment   banking  fees  incurred  and  subsequent
conversion  price resets) and the  accounting for warrants and options issued to
non-employees.  Our  interpretation  and  application  of EITF No.  00-27,  FASB
Statement  133,  EITF  98-5  and  EITF  00-19  was not  correct  at the time the
convertible debentures were initially recorded (2003 through July 2004), and our
interpretation  and  application  of FASB  statement  No. 123 was not correct in
recording certain warrant and option issuances to non-employees.  In March 2006,
we increased  the time  allocated by our  financial  consultant  with regards to
remediating  these  disclosed  internal  control  weaknesses  and the  financial
consultant will spend  additional  time  monitoring our internal  controls on an
on-going basis. In addition,  we have subscribed to CCH's  "Accounting  Research
Manager,"  a  recognized  on-line  service  in  order  to  maintain   up-to-date
accounting  guidance to enhance internal  control over both financial  reporting
and disclosure requirements.

Report of Independent Registered Public Accounting Firm on Internal Control Over
Financial Reporting

Board of Directors and Stockholders
Hemispherx Biopharma, Inc.
Philadelphia, Pennsylvania

      We have audited management's  assessment,  included in Management's Report
on Internal Control Over Financial Reporting,  that Hemispherx  Biopharma,  Inc.
did not  maintain  effective  internal  control over  financial  reporting as of
December 31, 2005,  because of the effect of material  weaknesses  identified in
management's    assessment   based   on   criteria   established   in   Internal
Control--Integrated   Framework   issued   by  the   Committee   of   Sponsoring
Organizations of the Treadway Commission (COSO).  Hemispherx  Biopharma,  Inc.'s
management  is  responsible  for  maintaining  effective  internal  control over
financial  reporting  and for its  assessment of the  effectiveness  of internal
control over financial reporting. Our responsibility is to express an opinion on
management's  assessment  and an opinion on the  effectiveness  of the Company's
internal control over financial reporting based on our audit.

      We  conducted  our audit in  accordance  with the  standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and  perform  the audit to obtain  reasonable  assurance  about  whether
effective  internal  control over  financial  reporting  was  maintained  in all
material  respects.  Our audit included  obtaining an  understanding of internal
control over financial reporting,  evaluating management's  assessment,  testing
and evaluating the design and operating  effectiveness of internal control,  and
performing   such  other   procedures   as  we   considered   necessary  in  the
circumstances.  We believe that our audit  provides a  reasonable  basis for our
opinion.

      A  company's  internal  control  over  financial  reporting  is a  process
designed to provide reasonable  assurance regarding the reliability of financial
reporting and the preparation of financial  statements for external  purposes in
accordance with generally accepted accounting  principles.  A company's internal
control over financial reporting includes those policies and procedures that (1)
pertain to the maintenance of records that, in reasonable detail, accurately and
fairly reflect the  transactions  and dispositions of the assets of the company;
(2) provide reasonable  assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting  principles,  and that receipts and  expenditures  of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of  unauthorized  acquisition,  use, or  disposition  of the company's
assets that could have a material effect on the financial statements.


                                       75


      Because of its  inherent  limitations,  internal  control  over  financial
reporting  may not prevent or detect  misstatements.  Also,  projections  of any
evaluation  of  effectiveness  to future  periods  are  subject to the risk that
controls may become  inadequate  because of changes in  conditions,  or that the
degree of compliance with the policies or procedures may deteriorate.

      A material  weakness is a control  deficiency,  or  combination of control
deficiencies,  that  result in more  than a remote  likelihood  that a  material
misstatement of the annual or interim financial statements will not be prevented
or detected. The following material weaknesses have been identified and included
in management's assessment.

      As of December 31, 2005, the Company did not maintain  effective  controls
over the financial  statement  close and reporting  process  because the Company
lacked a complement  of personnel  able to devote  sufficient  time and adequate
financial  reporting  expertise  commensurate  with the  quarterly  and year-end
financial  statement  close  requirements,  which  include  financial  statement
preparation and disclosures.

      As of December  31, 2005 the Company did not  maintain  effective  control
over  the  initial  recording  of  the  convertible  debentures  that  contained
beneficial  conversion  features,  including  incorrect  recording of investment
banking fees incurred and subsequent  debenture  conversion  price resets dating
back to 2003 and the accounting for warrants and options.

      The material weaknesses were considered in determining the nature,  timing
and extent of the audit tests applied in our audit of the Company's consolidated
financial  statements as of and for the year ended  December 31, 2005,  and this
report  does not  affect our  report  dated  June 1, 2006 on those  consolidated
financial statements.

      In our opinion,  management's  assessment that Hemispherx Biopharma,  Inc.
did not  maintain  effective  internal  control over  financial  reporting as of
December 31, 2005,  is fairly  stated,  in all material  respects,  based on the
criteria  established in Internal  Control-Integrated  Framework issued by COSO.
Also, in our opinion,  Hemispherx  Biopharma,  Inc. because of the effect of the
material  weaknesses  described above on the achievement  objectives and control
criteria,  the Company  has not  maintained  effective  control  over  financial
reporting as of December 31, 2005, based on the criteria established in Internal
Control-Integrated Framework issued by COSO.

      We have also audited,  in accordance  with standards of the Public Company
Accounting  Oversight Board (United States),  the consolidated balance sheets of
Hemispherx  Biopharma,  Inc. and  subsidiaries as of December 31, 2005 and 2004,
and the related consolidated statements of operations,  changes in stockholders'
equity and comprehensive loss, and cash flows for each of the three years in the
period ended  December 31, 2005,  and our report dated June 1, 2006 expressed an
unqualified opinion thereon.

securities,  to  file  reports  with  the  Securities  and  Exchange  Commission

Employment and Change in Control Agreements

      On March 11, 2005, our board of directors,  at the  recommendation  of the
Compensation  Committee,  approved an amended and restated employment  agreement
and an amended and restated engagement agreement with Dr. William A. Carter.

      The amended and restated  employment  agreement  provides for Dr. Carter's
employment as our Chief  Executive  Officer and Chief  Scientific  Officer until
December  31,  2010  unless  sooner  terminated  for  cause or  disability.  The
agreement automatically renews for successive one year periods after the initial
termination  date unless we or Dr. Carter give written notice otherwise at least
ninety days prior to the termination date or any renewal period.  Dr. Carter has
the right to terminate  the  agreement  on 30 days' prior  written  notice.  The
initial  base  salary  retroactive  to January 1, 2005 is  $290,888,  subject to
adjustment based on the average increase or decrease in the Consumer Price Index
for the prior year. In addition,  Dr. Carter could receive an annual performance
bonus  of up to  25%  of  his  base  salary,  at  the  sole  discretion  of  the
Compensation  Committee of the board of directors,  based on his  performance or
our  operating  results.  Dr.  Carter will not  participate  in any  discussions
concerning the determination of his annual bonus. Dr. Carter is also entitled to
an incentive  bonus of 0.5% of the gross proceeds  received by us from any joint
venture  or  corporate  partnering  arrangement.  Dr.  Carter's  agreement  also
provides that he be paid a base salary and benefits  through the last day of the
then term of the agreement if he is terminated without "cause",  as that term is
defined in agreement. In addition,  should Dr. Carter terminate the agreement or
the  agreement  be  terminated  due to his death or  disability,  the  agreement
provides that Dr Carter be paid a base salary and benefits  through the last day
of the month in which the  termination  occurred  and for an  additional  twelve
month period. Pursuant to his original agreement, Dr. Carter was granted options
to purchase  73,728 (post split)  shares in 1991.  The exercise  period of these
options  was  extended  through  December  31,  2010 and,  should  Dr.  Carter's
employment agreement be extended beyond that date, the option exercise period is
further extended to the last day of the extended employment period.

      The amended and restated engagement  agreement,  retroactive to January 1,
2005,  provides for our  engagement  of Dr.  Carter as a  consultant  related to
patent  development,  as one of our  directors  and as chairman of the Executive
Committee  of our board of  directors  until  December  31, 2010  unless  sooner
terminated  for cause or  disability.  The  agreement  automatically  renews for
successive  one year periods after the initial  termination  date or any renewal
period.  Dr.  Carter has the right to terminate  the agreement on 30 days' prior
written notice. The initial base fee as of January 1, 2004 is $207,777,  subject
to annual  adjustments  equal to the  percentage  increase or decrease of annual
dollar value of directors' fees provided to our directors during the prior year.
The annual fee is further subject to adjustment based on the average increase or
decrease in the Consumer Price Index for the prior year. In addition, Dr. Carter
could receive an annual  performance  bonus of up to 25% of his base fee, at the
sole direction of the Compensation Committee of the board of directors, based on
his performance.  Dr. Carter will not participate in any discussions  concerning
the  determination  of this annual bonus.  Dr. Carter's  agreement also provides
that he be paid  his  base fee  through  the  last  day of the then  term of the
agreement if he is terminated  without  "cause",  as that term is defined in the
agreement.  In  addition,  should Dr.  Carter  terminate  the  agreement  or the
agreement be terminated due to his death or disability,  the agreement  provides
that Dr.  Carter be paid fees due him through the last day of the month in which
the termination occurred and for an additional twelve month period.


                                       86


      On February 14, 2005 we entered  into an agreement  with The Sage Group of
Branchburg,  New Jersey for R. Douglas Hulse, an Executive  Director of The Sage
Group,  to serve as President  and Chief  Operating  Officer of our company.  In
addition,  other  Sage  Group  principals  and  Senior  Directors  will  be made
available  to assist as needed.  The  engagement  is expected to continue  for a
period of 18 months;  however,  it is  terminable  on 30 days written  notice by
either party after 12 months.  Compensation  for the services include a ten year
warrant to purchase  250,000  shares of our common stock at an exercise price of
$1.55.  These warrants were issued to Sage Healthcare  Advisors,  LLC and are to
vest at the rate of 12,500 per month of the engagement  with 25,000 vesting upon
completion of the eighteenth month. Vesting accelerates in the event of a merger
or a purchase of a majority of our assets or equity. We valued these warrants at
$256,000  utilizing  the  Black-Scholes  Method.  As of December 31,  2005,  the
$150,000 was expensed to stock compensation  expense.  The Sage Group also is to
receive a monthly  retainer  of  $10,000  for the period of the  engagement.  In
addition, for each calendar year (or part thereof) during which the agreement is
in effect,  The Sage Group will be entitled to an  incentive  bonus in an amount
equal to 0.5% of the gross  proceeds  received  by us during  such year from any
joint ventures or corporate  partnering  arrangements.  After termination of the
agreement,  The Sage Group will only be entitled to receive the incentive  bonus
based upon gross proceeds  received by us during the two year period  commencing
on the  termination  of the  agreement  with  respect to any joint  ventures  or
corporate  partnering  arrangements  entered  into by us during  the term of the
agreement.  Mr. Hulse will devote approximately two to two and one half days per
week to our business.

      We entered into an engagement  agreement,  retroactive to January 1, 2005,
with Ransom W. Etheridge  which provides for Mr.  Etheridge's  engagement as our
General  Counsel until  December 31, 2009 unless sooner  terminated for cause or
disability.  The agreement  automatically renews for successive one year periods
after the initial  termination  date  unless we or Mr.  Etheridge  give  written
notice  otherwise  at least  ninety  days prior to the  termination  date or any
renewal  period.  Mr.  Etheridge  has the right to terminate the agreement on 30
days' prior written  notice.  The initial annual fee for services is $96,000 and
is annually  subject to adjustment  based on the average increase or decrease in
the Consumer  Price Index for the prior year.  Mr.  Etheridge's  agreement  also
provides  that he be paid all fees  through the last day of then current term of
the agreement if he is terminated without "cause" as that term is defined in the
agreement.  In addition,  should Mr.  Etheridge  terminate  the agreement or the
agreement be terminated due to his death or disability,  the agreement  provides
that Mr. Etheridge be paid the fees due him through the last day of the month in
which the termination  occurred and for an additional  twelve month period.  Mr.
Etheridge will devote approximately 85% of his business time to our business.

      We entered into an amended and restated engagement agreement,  retroactive
to January 1, 2005,  with Robert E. Peterson which  provides for Mr.  Peterson's
engagement as our Chief Financial  Officer until December 31, 2010 unless sooner
terminated for cause or disability.  Mr. Peterson has the right to terminate the
agreement on 30 days' prior written notice.  The initial annual fee for services
is $202,680 and is annually  subject to increases based on the average  increase
in the cost of inflation index for the prior year. Mr. Peterson shall receive an
annual bonus in each year that our Chief  Executive  Officer is granted a bonus.
The bonus shall equal a percentage of Mr.  Peterson's  base annual  compensation
comparable to the percentage bonus received by the Chief Executive  Officer.  In
addition,  Mr.  Peterson  shall  receive  bonus  compensation  upon Federal Drug
Administration approval of commercial application of Ampligen(R). Mr. Peterson's
agreement  also  provides  that he be paid all fees through the last day of then
current term of the agreement if he is terminated  without  "cause" as that term
is defined in the  agreement.  In addition,  should Mr.  Peterson  terminate the
agreement or the agreement be  terminated  due to his death or  disability,  the
agreement  provides that Mr.  Peterson be paid the fees due him through the last
day of the month in which the termination  occurred and for an additional twelve
month period. Mr. Peterson will devote approximately 85% of his business time to
our business.


                                       87


      On March 11, 2005 the Board of Directors, deeming it essential to the best
interests  of our  shareholders  to  foster  the  continuous  engagement  of key
management  personnel  and  recognizing  that, as is the case with many publicly
held  corporations,  a change of control might occur and that such  possibility,
and the uncertainty and questions which it might raise among  management,  might
result in the departure or distraction of management  personnel to the detriment
of our company and our  shareholders,  determined to reinforce and encourage the
continued  attention  and  dedication  of  members  of our  management  to their
engagement   without   distraction  in  the  face  of   potentially   disturbing
circumstances arising from the possibility of a change in control of our company
and entered into identical  agreements  regarding change in control with William
A. Carter, our Chief Executive Officer and Chief Scientific  Officer,  Robert E.
Peterson,  our Chief  Financial  Officer  and Ransom W.  Etheridge,  our General
Counsel.  Each of the agreements  regarding  change in control became  effective
March  11,  2005  and  continue  through  December  31,  2007 and  shall  extend
automatically  to the third  anniversary  thereof  unless we give  notice to the
other party prior to the date of such extension that the agreement term will not
be extended. Notwithstanding the foregoing, if a change in control occurs during
the term of the agreements, the term of the agreements will continue through the
second anniversary of the date on which the change in control occurred.  Each of
the  agreements  entitles  William A. Carter,  Robert E.  Peterson and Ransom W.
Etheridge,  respectively,  to change of  control  benefits,  as  defined  in the
agreements  and  summarized   below,   upon  their  respective   termination  of
employment/engagement  with our company during a potential change in control, as
defined  in the  agreements  or after a change in  control,  as  defined  in the
agreements,  when  their  respective  terminations  are caused (1) by us for any
reason other than permanent disability or cause, as defined in the agreement (2)
by  William  A.  Carter,   Robert  E.  Peterson   and/or  Ransom  W.  Etheridge,
respectively,  for good reason as defined in the agreement or, (3) by William A.
Carter,  Robert E. Peterson  and/or Ransom W.  Etheridge,  respectively  for any
reason during the 30 day period commencing on the first date which is six months
after the date of the change in control.

The benefits for each of the foregoing executives would be as follows:

      o     A lump sum cash  payment of three  times his base  salary and annual
            bonus amounts; and

      o     Outplacement benefits.

Each  agreement  also  provides  that the  executive is entitled to a "gross-up"
payment  to make him whole  for any  federal  excise  tax  imposed  on change of
control or severance  payments  received by him.  Dr.  Carter's  agreement  also
provides for the following benefits:


                                       88


      o     Continued  insurance  coverage through the third  anniversary of his
            termination; and

      o     Retirement  benefits computed as if he had continued to work for the
            above period.

Compensation of Directors

      The  compensation  package  for  non-employee  members  of  the  Board  of
Directors was changed on September 9, 2003. Board member  compensation  consists
of an annual  retainer  of $100,000 to be paid 50% in cash and 50% in our common
stock.  On  September  9,  2003 the  Directors  approved  a 10 year  plan  which
authorizes up to 1,000,000 shares for use in supporting this compensation  plan.
The number of shares  paid  shall have a value of $12,500  with the value of the
shares being determined by the closing price of our common stock on the American
Stock  Exchange  on the last  day of the  calendar  quarter.  In  addition,  all
non-employee  directors  received some  compensation in 2003 for special project
work performed on our behalf. This project work ceased as of September 30, 2003.
All directors have been granted options to purchase common stock under our Stock
Option  Plans  and/or  Warrants  to  purchase  common  stock.  We  believe  such
compensation  and payments  are  necessary in order for us to attract and retain
qualified outside directors.

2004 Equity Incentive Plan

      Our 2004 Equity  Incentive  Plan ("2004  Plan")  provides for the grant of
non-qualified and incentive stock options, stock appreciation rights, restricted
stock and other stock awards to our employees,  directors, officers, consultants
and advisors  for the  purchase of up to an  aggregate  of  8,000,000  shares of
common stock. The 2004 plan is administered by the board of directors, which has
complete  discretion to select eligible  individuals to receive and to establish
the terms of grants  under the plan.  Stock  options  awarded  under the  Equity
Incentive  Plan may be  exercisable at such times (not later than 10 years after
the date of grant) and at such exercise  prices (not less than fair market value
at the date of  grant) as the Board may  determine.  The Board may  provide  for
options to become immediately  exercisable upon a "change in control" as defined
in the plan. The number of shares of common stock  available for grant under the

receive and to  establish  the terms of option  grants.  The number of shares of
common stock  available  for grant under the 1990 Plan is subject to  adjustment

401(K) Plan


                                       89


      In December 1995, we established a defined  contribution  plan,  effective
January 1, 1995,  entitled the Hemispherx  Biopharma  employees  401(K) Plan and
Trust  Agreement.  All of our full time employees are eligible to participate in
the 401(K) plan following one year of employment. Subject to certain limitations
imposed by federal tax laws,  participants  are eligible to contribute up to 15%
of their salary (including bonuses and/or commissions) per annum.  Participants'
contributions  to  the  401(K)  plan  may be  matched  by  Hemispherx  at a rate
determined  annually by the board of  directors.  Each  participant  immediately
vests in his or her deferred salary contributions,  while our contributions will
vest  over  one  year.  See  Note 12 to the  consolidated  financial  statements
contained herein.

Compensation Committee Interlocks and Insider Participation

      Our  Compensation  Committee of the Board of  Directors  consists of , the
Committee Chairman, William Mitchell, M.D., Richard Piani, Dr. Iraj E. Kiani and
are all independent directors. There are no interlocking relationships.

Compensation Committee Report on Compensation

      The Compensation  Committee makes recommendations  concerning salaries and
compensation for our employees and consultants.

      The following report of the compensation committee discusses our executive
compensation  policies and the basis of the  compensation  paid to our executive
officers in 2005.

      In general, the compensation committee seeks to link the compensation paid
to each executive  officer to the  experience and  performance of such executive
officer. Within these parameters, the executive compensation program attempts to
provide an overall  level of executive  compensation  that is  competitive  with
companies   of   comparable   size  and  with  similar   market  and   operating
characteristics.

      There are three elements in our executive total compensation  program, all
determined by individual  and corporate  performance as specified in the various
employment agreements; base salary, annual incentive, and long-term incentives.

Base Salary

      The Summary  Compensation  Table shows  amounts  earned during 2005 by our
executive  officers.  The base compensation of such executive officers is set by
terms of the employment agreement entered into with each such executive officer.
We established  the base salaries for Chief  Executive  Officer,  Dr. William A.
Carter  under an  employment  agreement  in  December  3, 1998 (as  amended  and
restated on March 11, 2005),  which  provides for a base salary of $290,888.  In
addition,  we entered  into an agreement  with Dr.  Carter for his services as a
consultant  related  to patient  development,  development  of patents  and as a
member of our Board of Directors.  This agreement  establishes a base annual fee
of $207,777.  Both agreements are subject to annual cost of living  adjustments.
Dr. Carter is entitled to an annual  performance  bonus of up to 25% of the base
salary of each agreement at the discretion of the compensation  committee of the
Board of Directors.

      On March 11, 2005, we entered into an extended  engagement  agreement with
Robert E. Peterson, Chief Financial Officer retroactive to January 1, 2005 for a
base annual fee of $202,680 until December 31, 2010.  Mr.  Peterson's  agreement
allows for annual cost of living increases and a performance bonus.


                                       90


      On March 11, 2005, we entered into an engagement  agreement with Ransom W.
Etheridge,  Corporate  General  Counsel,  retroactive  to January 1, 2005 for an
annual fee of $96,000 until December 31, 2009.

Annual Incentive

      Our Chief Executive  Officer and our Chief Financial  Officer are entitled
to an annual incentive bonus as determined by the  compensation  committee based
on such executive  officers'  performance during the previous calendar year. The
cash bonus awarded to our Chief Executive  Officer in 2004 and 2005 and the cash
bonus awarded to the Chief  Financial  Officer in 2004 and 2005 were  determined
based on this provision in their employment agreements.

Long-Term Incentives

      We grant long-term  incentive  awards  periodically to align a significant
portion of the executive compensation program with stockholder interest over the
long-term  through  encouraging  and  facilitating  executive  stock  ownership.
Executives are eligible to participate in our incentive stock option plans.  Our
Chief Executive Officer and President,  Dr. William Carter,  received a grant of
645,000 stock  options in 2005 of which  535,000 were issued to replace  options
previously awarded that expired.  These options are exercisable at rates varying
from $1.75 to $2.87 per share. The options vested on the date of grant.

      On April 26, 2005, our Chief Financial  Officer,  Robert E. Peterson,  was
granted  100,000 stock options  exercisable at $1.75 per share expiring on April
26, 2015 unless  previously  exercised.  On  December 8, 2005 Mr.  Peterson  was
granted 10,000 stock options exercisable at $2.61 per share expiring on December
8, 2015.

      Ransom Etheridge, our Corporate Secretary and General Counsel, was awarded
100,000 stock options on April 26, 2005  exercisable at $1.75 per share expiring
April 26, 2015, unless previously exercised.

Audit Fees

      Represents fees for  professional  services  provided for the audit of our
annual financial statements, audit of the effectiveness of internal control over
financial  reporting,  services  that are  performed  to comply  with  generally
accepted auditing standards,  and review of our financial statements included in
our quarterly  reports and services in connection  with statutory and regulatory
filings.

Audit-Related Fees

      Represents the fees for assurance and related services that are reasonably
related to the performance of the audit or review of our financial statements.

      The Audit  Committee has determined  that BDO Seidman,  LLP's rendering of
these non-audit services is compatible with maintaining  auditors  independence.
The Board of Directors considers BDO Seidman,  LLP to be well qualified to serve
as our  independent  public  accountants.  The committee also  pre-approved  the
charges for services performed in 2005.

      The Audit  Committee  pre-approves  all  auditing  services  and the terms
thereof  (which  may  include  providing  comfort  letters  in  connection  with
securities  underwriting) and non-audit  services (other than non-audit services
prohibited  under Section 10A(g) of the Exchange Act or the applicable  rules of
the SEC or the Public Company  Accounting  Oversight Board) to be provided to us
by the independent auditor;  provided,  however, the pre-approval requirement is
waived with respect to the  provisions  of non-audit  services for us if the "de
minimus"  provisions of Section 10A (i)(1)(B) of the Exchange Act are satisfied.
This authority to pre-approve non-audit services may be delegated to one or more
members of the Audit  Committee,  who shall present all decisions to pre-approve
an activity to the full Audit  Committee  at its first  meeting  following  such
decision.

             Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Hemispherx Biopharma, Inc.

      We have audited the accompanying consolidated balance sheets of Hemispherx
Biopharma,  Inc.  and  subsidiaries  as of  December  31,  2004 and 2005 and the
related consolidated  statements of operations,  changes in stockholders' equity
and comprehensive  loss and cash flows for each of the three years in the period
ended December 31, 2005. We have also audited the financial  statement  schedule
listed under Item 15(a). These consolidated  financial  statements and financial
statement  schedule are the  responsibility  of the  Company's  management.  Our
responsibility  is  to  express  an  opinion  on  these  consolidated  financial
statements based on our audits.

      We  conducted  our audits in  accordance  with  auditing  standards of the
Public Company  Accounting  Oversight  Board (United  States).  Those  standards
require that we plan and perform the audit to obtain reasonable  assurance about
whether the financial  statements and financial  statement  schedule are free of
material  misstatement.  An audit includes examining,  on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

      In our opinion,  the consolidated  financial  statements referred to above
present fairly, in all material  respects,  the financial position of Hemispherx
Biopharma,  Inc.  and  subsidiaries  as of  December  31,  2004 and 2005 and the
results of their  operations and their cash flows for each of the three years in
the period ended  December 31, 2005 in  conformity  with  accounting  principles
generally  accepted in the United  States.  Also, in our opinion,  the financial
statement  schedule presents fairly, in all material  respects,  the information
set forth  therein for each of the three years in the period ended  December 31,
2005.

      As discussed  in Note 2, the Company has restated its balance  sheet as of
December 31, 2004 and the  statements  of  operations,  changes in  stockholders
equity and  comprehensive  loss and cash flows for the years ended  December 31,
2003 and 2004.

      We also have  audited,  in  accordance  with the  standards  of the Public
Company  Accounting  Oversight  Board  (United  States),  the  effectiveness  of
Hemispherx  Biopharma,  Inc.'s internal  control over financial  reporting as of
December  31,  2005,  based  on  criteria  established  in  Internal  Control  -
Integrated Framework issued by the Committee of Sponsoring  Organizations of the
Treadway  Commission  (COSO) and our  report  dated  June 1, 2006  expressed  an
unqualified opinion on management's  assessment of the effectiveness of internal
control over financial  reporting and adverse  opinion on the  effectiveness  of
internal control over financial  reporting  because of the existence of material
weaknesses.

                   HEMISPHERX BIOPHARMA, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Business

      Hemispherx   Biopharma,   Inc.  and   subsidiaries   (the  Company)  is  a
biopharmaceutical  company  engaged in the  clinical  development,  manufacture,
marketing and  distribution  of new drug entities based on natural immune system
enhancing  technologies  for the  treatment  of viral and immune  based  chronic
disorders.  The Company was founded in the early 1970s, as a contract researcher
for the National  Institutes  of Health.  The Company has  established  a strong
foundation of  laboratory,  pre-clinical,  and clinical data with respect to the
development of nucleic acids to enhance the natural  antiviral defense system of
the  human  body and to aid the  development  of  therapeutic  products  for the
treatment  of  chronic  diseases.   The  Company  owns  a  U.S.  Food  and  Drug
Administration ("FDA") approved GMP (good manufacturing  practice) manufacturing
facility in New Jersey.

      The  Company's  flagship  products  include   Ampligen(R)  and  Alferon  N
Injection(R).   Ampligen(R)  is  an  experimental   drug   undergoing   clinical
development  for the treatment  of:  Myalgic  Encephalomyelitis/Chronic  Fatigue
Syndrome  ("ME/CFS" or "CFS"), and HIV. In August 2004, we completed a Phase III
clinical  trial ("AMP 516") treating over 230 ME/CFS  patients with  Ampligen(R)
and are in the process of preparing a new drug  application  ("NDA") to be filed
with the FDA.

      In March 2004, the Company  completed the  step-by-step  acquisition  from
Interferon  Sciences,  Inc.  ("ISI")  of  ISI's  commercial  assets,  Alferon  N
Injection(R)  inventory,  a worldwide  license for the production,  manufacture,
use,  marketing and sale of Alferon N Injection(R),  as well as, a 43,000 square
foot   manufacturing   facility  in  New  Jersey  and  the  acquisition  of  all
intellectual property related to Alferon N Injection(R).  Alferon N Injection(R)
is a natural alpha  interferon  that has been approved by the FDA for commercial
sale for the  intra-lesional  treatment  of  refractory  or  recurring  external
genital  warts in  patients  18  years  of age or  older.  The  acquisition  was
completed  in Spring  2004 with the  acquisition  of all world  wide  commercial
rights.

      The consolidated  financial statements include the financial statements of
Hemispherx Biopharma,  Inc. and its wholly-owned  subsidiaries.  The Company has
three  domestic  subsidiaries  BioPro Corp.,  BioAegean  Corp.  and Core BioTech
Corp., all of which are incorporated in Delaware and are dormant.  The Company's
foreign subsidiaries  include Hemispherx Biopharma Europe N.V./S.A.  established
in  Belgium  in 1998 and  Hemispherx  Biopharma  Europe  S. A.  incorporated  in
Luxemburg  in  2002,  which  have  limited  or  no  activity.   All  significant
intercompany balances and transactions have been eliminated in consolidation.

(2) Restatements


                                      F-8


      (a)   Based on SEC guidance  presented  at the 2005 annual AICPA  National
            Conference  on  current  SEC and  PCAOB  developments,  the  Company
            re-evaluated  its accounting for its March 2003, July 2003,  October
            2003,  January  2004 and July 2004  Debentures  (collectively,  "the
            Debentures") to determine  whether the embedded  conversion  options
            required  bifurcation  and fair value  accounting in accordance with
            FASB Statement No. 133,  "Accounting for Derivative  Instruments and
            Hedging  Activities",  and EITF 00-19,  "Accounting  for  Derivative
            Financial  Instruments  Indexed  to,  and  Potentially  Settled in a
            Company's Own Stock". The Company concluded that bifurcation was not
            required  and that EITF  00-27:  "Application  of Issue No.  98-5 to
            Certain  Convertible  Instruments"  ("EITF  00-27") should have been
            applied. The Company did initially apply EITF 00-27, however as part
            of performing an analysis on the  guidelines set forth in EITF 00-27
            it was  determined  that the initial  accounting  treatment  for the
            Debentures and conversion  price resets that was originally  applied
            and reflected in the financial  statements included in the Company's
            Annual  Reports on Form 10-K for the years ended  December  31, 2004
            and 2003, and in the Company's Quarterly Reports on Form 10-Q during
            the  quarterly  periods  in  fiscal  2003,  2004 and  2005  were not
            correctly  applied  and  that,  therefore,   a  restatement  of  the
            Company's financial  statements for the periods referenced above was
            required.  To properly  account for the initial  calculation  of the
            discount and the conversion price resets triggered upon the issuance
            of the  issuance of the October 2003  Debenture  and the August 2004
            Private  Placement  (See Notes 8 & 9 below for more details on these
            resets), it was determined,  under guidance from EITF 00-27 that the
            debt  discount  should be  restated  for the  Debentures.  The total
            impact of this restatement on the Company's  statement of operations
            was to decrease the net loss applicable to common  stockholders  for
            the year ended  December 31, 2004 by  $2,959,000 or $0.07 per share,
            and to increase the net loss  applicable to common  stockholders  by
            $287,000 or $0.01 per share for the year ended December 31, 2003.

      (b)   The  estimation  of  fair  value  ascribed  to  and  the  accounting
            treatment of the investment  banking fees paid to Cardinal  Capital,
            LLC  ("Cardinal")  in connection  with the Debenture  issuances,  at
            inception,  was inaccurately  reflected in the financial  statements
            included in the  Company's  Annual Report on Form 10-K for the years
            ended  December  31,  2004 and  2003,  and the  Company's  Quarterly
            reports on Form 10-Q during the  quarterly  periods in fiscal  2003,
            2004  and  2005  and as a  result  a  restatement  of the  Company's
            financial  statements for the periods referenced above was required.
            In connection with the initial recording of the Debentures mentioned
            above,  it was determined that the fair value of the warrants issued
            as investment  banking fees paid to Cardinal,  be accounted for as a
            discount to the  Debentures.  These  investment  banking fees should
            have been capitalized as deferred financing costs and amortized over
            the life of the  Debentures  or charged to  earnings  on the earlier
            conversion thereof. In addition, the initial calculation of the fair
            value of the  warrants  issued to Cardinal as part of the  Debenture
            issuances was  determined to be computed  incorrectly at the time of
            issuance.  The total  impact of this  restatement  on the  Company's
            statement of operations  was to decrease the net loss  applicable to
            common stockholders for the year ended December 31, 2004 by $263,000
            or $0.01 per share and to increase the net loss applicable to common
            stockholders  for the year ended  December  31,  2003 by $158,000 or
            $0.00 per share.


                                      F-9


      (c)   The  accounting  treatment  set  forth in FASB  Statement  No.  123,
            "Accounting for Stock-Based  Compensation",  for the issuance of the
            June  2008,  May 2009  and June  2009  Warrants  (collectively  "the
            Warrants") (See Note 8 below for more details on these transactions)
            that was  originally  interpreted  and  reflected  in the  financial
            statements  included in our Annual Report on Form 10-K for the years
            ended December 31, 2003 and 2004, was not correctly applied and as a
            result a  restatement  of our  financial  statements  for the period
            referenced  above was required.  The Warrants issued as incentive to
            exercise  prior  warrant  issuances  should be reflected as a deemed
            dividend at the date of issuance  where  previously  these  warrants
            were either  recorded as additional  debt discount or as a financing
            charge at date of issuance.  The total impact of this restatement on
            our statement of operations was to decrease  finance charges for the
            years ended  December 31, 2003 and 2004 by $1,320,000 and $4,031,000
            or $0.04 and $0.08 per share, respectively and increase the net loss
            applicable to common stockholders due to the deemed dividend for the
            years ended  December 31, 2003 and 2004 by $1,320,000 and $4,031,000
            or $0.04 and $0.08 per share, respectively.

(3) Summary of Significant Accounting Policies

(a) Cash and Cash Equivalents

      Cash  equivalents  consist  of money  market  certificates  and  overnight
repurchase  agreements  collateralized  by money market securities with original
maturities  of less  than  three  months,  with  both a cost and  fair  value of
$8,813,000 and $3,827,000 at December 31, 2004 and 2005, respectively.

(b) Short-term Investments

      Investments  with  original  maturities of more than three months and less
than 12 months and marketable  equity  securities  are considered  available for
sale. The  investments  classified as available for sale include debt securities
and  equity  securities  carried  at  estimated  fair  value of  $7,924,000  and
$12,377,000 at December 31, 2004 and 2005 respectively. The unrealized gains and
losses are recorded as a component of shareholders' equity.

(c) Investments in unconsolidated affiliates

      Investments  in  companies  in which the Company  owns 20% or more and not
more than 50% are accounted for using the equity method of accounting.

      Investments  in companies in which the Company owns less than 20% and does
not exercise a significant  influence are accounted for using the cost method of
accounting.

      In May 2000, the Company acquired an interest in Chronix  Biomedical Corp.
("CHRONIX").  Chronix  focuses upon the  development of diagnostics  for chronic
diseases.  The Company issued 100,000 shares of common stock to Chronix toward a
total equity investment of $700,000. Pursuant to a strategic alliance agreement,
the Company  provided  Chronix with $250,000 for research and  development in an
effort to develop intellectual property on potential new products for diagnosing
and treating various chronic illnesses such as ME/CFS. These costs were expensed
as incurred.  The  strategic  alliance  agreement  provides the Company  certain
royalty rights with respect to certain diagnostic technology developed from this
research and a right of first refusal to license certain therapeutic  technology
developed  from this research.  The strategic  alliance  agreement  provides the
Company with a royalty payment of 10% of all net sales of diagnostic  technology
developed by Chronix for diagnosing Chronic Fatigue Syndrome,  Gulf War Syndrome
and Human Herpes  Virus-6  associated  diseases.  The royalty  continues for the
longer of 12 years from  September 15, 2000 or the life of any patent(s)  issued
with regard to the diagnostic technology.  The strategic alliance agreement also
provides  the Company  with the right of first  refusal to acquire an  exclusive
worldwide license for any and all therapeutic technology developed by Chronix on
or before  September 14, 2012 for treating  Chronic Fatigue  Syndrome,  Gulf War
Syndrome and Human Herpes Virus-6 associated diseases. During the quarters ended
December 31, 2002 and September 30, 2004, the Company recorded a non-cash charge
of $292,000 and $373,000, respectively, with respect to the Company's investment
in Chronix.  This impairment  reduces the Company's  carrying value to reflect a
permanent  decline in Chronix's  market value based on its then proposed  equity
offerings.

Less accumulated depreciation and amortization                884            999
                                                           ------         ------

                                                           ======         ======

      Property and equipment  consist of land,  building,  furniture,  fixtures,
office  equipment,   and  leasehold   improvements  and  is  recorded  at  cost.
Depreciation  and amortization is computed using the  straight-line  method over
the  estimated  useful  lives of the  respective  assets,  ranging  from five to
thirty-nine years.  Depreciation and amortization expense was $80,000,  $113,000
and $114,000 for 2003, 2004 and 2005, respectively.

      Construction in progress  consists of funds used for the  construction and
installation of the Company's  Ampligen(R)  raw material  production line within
the  Company's New Jersey  facility.  As of December 31, 2005,  construction  in
progress was $821,000.  The Company estimates the total cost of establishing the
production line to be $1,900,000.

(e) Patent and Trademark Rights

      Patents and trademarks are stated at cost  (primarily  legal fees) and are
amortized using the straight line method over the established  useful life of 17
years.  The Company  reviews its patents and trademark  rights  periodically  to
determine  whether they have continuing  value. Such review includes an analysis
of the patent and  trademark's  ultimate  revenue and  profitability  potential.
Management's  review  addresses  whether  each patent  continues to fit into the
Company's  strategic  business plans.  During the years ended December 31, 2003,
2004 and 2005,  the  Company  decided  not to pursue the  technology  in certain
countries  for  strategic  reasons and  recorded  impairment  charges of $5,000,
$223,000 and $194,000 respectively.  Amortization expense was $122,000, $104,000
and $87,000 in 2003, 2004 and 2005,  respectively.  The accumulated amortization
as of December 31, 2003, 2004 and 2005 is $2,150,000, $1,807,000 and $1,572,000,
respectively.

      As of December  31,  2005,  the  weighted  average  remaining  life of the
patents and trademarks was 9 years.  Amortization  of patents and trademarks for
each of the next five years is as follows:  2006 - $86,000, 2007 - $86,000, 2008
- $86,000, 2009 - $86,000 and 2010 - $86,000.

(f) Revenue and License Fee Income

      The Company executed a Memorandum of  Understanding  (MOU) in January 2004
with Astellas Pharma  ("Astellas"),  formally Fujisawa Deutschland GmbH, a major
pharmaceutical  corporation,  granting  them an  exclusive  option for a limited
number  of months to enter a Sales and  Distribution  Agreement  with  exclusive
rights to market Ampligen(R) for ME/CFS in Germany, Austria and Switzerland. The
Company received an initial fee of 400,000 Euros (approximately  $497,000 US) in
2004. On November 9, 2004,  Astellas exercised their right to terminate the MOU.
The Company  did not agree on the  process to be  utilized  in certain  European
Territories for obtaining commercial approval for the sale of Ampligen(R) in the
treatment of patients suffering from Chronic Fatigue Syndrome (CFS).  Instead of
a centralized  procedure,  and in order to obtain an earlier commercial approval
of Ampligen(R) in Europe,  the Company has determined to follow a  decentralized
filing procedure which was not anticipated in the MOU. The Company believed that
it  was in the  best  interest  of the  Company's  stockholders  to  potentially
accelerate  entry into  selected  European  markets  whereas  the  original  MOU
specified a centralized registration procedure. Pursuant to the agreement of the
parties the Company refunded 200,000 Euros ($248,000 USD) to Astellas during the
fourth quarter 2004. The Company recorded the remaining  200,000 Euros ($271,000
USD and $241,000 USD) as an accrued  liability as of December 31, 2004 and 2005,
respectively.


                                      F-15


      Revenue  from  the  sale  of  Ampligen(R)  under  cost  recovery  clinical
treatment  protocols  approved by the FDA is  recognized  when the  treatment is
provided to the patient.

      Revenues from the sale of Alferon N Injection(R)  are recognized  when the
product is shipped, as title is transferred to the customer.  The Company has no
other obligation associated with its products once shipment has occurred.

(g) Net Loss Per Share

      Basic and  diluted  net loss per  share is  computed  using  the  weighted
average  number of  shares  of  common  stock  outstanding  during  the  period.
Equivalent common shares, consisting of stock options and warrants including the
Company's  convertible  debentures,  amounted  to  19,566,217,   20,413,024  and
25,635,142  shares,  are excluded from the  calculation  of diluted net loss per
share for the years ended December 31, 2003, 2004 and 2005, respectively,  since
their effect is antidilutive.

(h) Accounting for Income taxes

      Deferred  income  tax  assets  and  liabilities  are  determined  based on
differences  between the financial  statement  reporting and tax bases of assets
and  liabilities and are measured using the enacted tax rates and laws in effect
when the differences are expected to reverse. The measurement of deferred income
tax assets is  reduced,  if  necessary,  by a  valuation  allowance  for any tax
benefits,  which are not expected to be realized.  The effect on deferred income
tax assets and  liabilities of a change in tax rates is recognized in the period
that such tax rate changes are enacted.

(i) Comprehensive loss

      Comprehensive  loss consists of net loss and net unrealized gains (losses)
on  securities  and is presented in the  consolidated  statements  of changes in
stockholders' equity and comprehensive loss.

(j) Use of Estimates

      The  preparation  of financial  statements  in conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the reported  amounts of revenues and expenses for the reporting
period. Actual results could differ from those estimates.

(k) Foreign currency translations

      Assets and liabilities of the Company's  foreign  operations are generally
translated into U.S. dollars at current exchange rates as of balance sheet date.
Revenues and  expenses  are  translated  at average  exchange  rates during each
period.  Transaction gains and losses that arise from exchange rate fluctuations
are included in the results of operations as incurred. The resulting translation
adjustments  are immaterial for all years presented and are included in interest
and other income on the consolidated statement of operations.


                                      F-16


(l) Recent Accounting Standard and Pronouncements:

      In  December  2004,  the FASB issued  Statement  of  Financial  Accounting
Standards No. 123 (Revised 2004),  "Share-Based Payment" ("SFAS 123R"). On April
14, 2005,  the Securities  and Exchange  Commission  issued an amendment to Rule
4-01 of  Regulation  S-X that allows  companies  to  implement  SFAS 123R at the
beginning of their next fiscal year,  instead of the next reporting  period that
begins after June 15, 2005 as originally required. Accordingly, the Company will
adopt  SFAS 123R  effective  January 1, 2006  using the  "modified  prospective"
method in which  compensation  cost is recognized  beginning  with the effective
date based on (a) the  requirements  of SFAS 123R for all  share-based  payments
granted after the effective  date and (b) the  requirements  of SFAS 123 for all
awards granted to employees prior to the effective date of SFAS 123R that remain
unvested on the effective date. In addition,  the Company expects to continue to
utilize the Black-Scholes  option-pricing  model,  which is an acceptable option
valuation  model in  accordance  with SFAS 123R,  to estimate the value of stock
options granted to employees.

      Beyond those restricted stock and stock option awards previously  granted,
the Company  cannot predict with certainty the impact of SFAS 123R on its future
consolidated  financial  statements  as the type and  amount of such  awards are
determined on an annual basis and encompass a potentially  wide range  depending
upon  the  compensation  decisions  made by the  Compensation  Committee  of the
Company's  Board of  Directors.  SFAS 123R also  requires  the  benefits  of tax
deductions in excess of compensation cost recognized in the financial statements
to be reported as a financing  cash flow,  rather than an operating cash flow as
currently  required under  Statement of Financial  Accounting  Standards No. 95,
"Statement  of Cash  Flows"  ("SFAS  95").  This  requirement,  to the extent it
exists,  will decrease net operating  cash flows and increase net financing cash
flows in periods subsequent to adoption. The Company believes this pronouncement
will have a material impact on its consolidated financial statements.

      On March 29, 2005, the SEC issued Staff Accounting  Bulletin No. 107 ("SAB
107") which  expresses the view of the SEC Staff  regarding the  interaction  of
SFAS 123R and certain SEC rules and  regulations  and provides the staff's views
regarding  the  valuation  of  share-based  payment  arrangements.  The  Company
believes  that the views  provided in SAB 107 are  consistent  with the approach
taken in the valuation and accounting  associated with share-based  compensation
issued in prior periods as well as those issued during 2005.

      In June 2005, the FASB's  Emerging  Issues Task Force ("EITF") issued EITF
Issue No. 05-02 "The Meaning of  "Conventional  Convertible  Debt Instrument" in
EITF Issue 00-19 "Accounting for Derivative  Financial  Instruments  Indexed to,
and Potentially Settled in, A Company's Own Stock",  which retains the exception
in paragraph 4 of EITF Issue No. 00-19 for conventional debt instruments.  Those
instruments in which the holder has an option to convert the  instrument  into a
fixed  number  of shares  (or a  corresponding  amount  of cash at the  issuer's
discretion)  and its ability to  exercise  the option is based on either (a) the
passage of time or (b) a contingent event,  should be considered  "conventional"
for purposes of applying that  exception.  The consensus  should be applied on a
prospective  basis  for new or  modified  instruments  starting  from the  third
quarter of 2005.  The adoption of EITF No. 05-02 did not have a material  effect
on the Company's consolidated financial statements or results of operations.


                                      F-17


      In November 2005, FASB issued FSP FAS 115-1 and FAS 124-1, "The Meaning of
Other-Than-Temporary  Impairment  and Its  Application  to Certain  Investments"
("FSP FAS 115-1"),  which provides  guidance on determining  when investments in
certain  debt  and  equity  securities  are  considered  impaired,   whether  an
impairment is  other-than-temporary,  and on measuring such impairment loss. FSP
FAS 115-1 also includes accounting  considerations subsequent to the recognition
of an  other-than-temporary  impairment and requires certain  disclosures  about
unrealized  losses  that  have  not  been  recognized  as   other-than-temporary
impairments.  FSP FAS 115-1 is  required  to be  applied  to  reporting  periods
beginning  after  December  15,  2005.  The Company is required to adopt FSP FAS
115-1 in the first quarter of 2006.  The Company does not expect the adoption of
this statement to have a material impact on the Company's  consolidated  results
of operations or financial condition.

      In November  2004,  the FASB issued  SFAS No. 151,  "Inventory  Costs - An
amendment of ARB No. 43,  Chapter 4" ("SFAS No.  151").  SFAS No. 151 amends the
guidance in Accounting Research Bulletin No. 43, Chapter 4, "Inventory Pricing,"
to  clarify  the  accounting  for  abnormal  amounts of idle  facility  expense,
freight, handling costs, and wasted material (spoilage).  Additionally, SFAS No.
151 requires that the  allocation of fixed  production  overheads to the cost of
conversion be based on the normal  capacity of the production  facilities.  SFAS
No. 151 is required to be adopted in the first quarter of 2006.  The Company has
determined  that the adoption of SFAS No. 151 will not have a material impact on
the consolidated financial statements.

      In  December  2004,  the FASB issued  Statement  of  Financial  Accounting
Standards No. 153 (SFAS 153"), "Exchanges of Non-monetary Assets-an amendment of
APB  Opinion  No.  29." SFAS 152  addresses  the  measurement  of  exchanges  of
non-monetary assets. It eliminates the exception from fair value measurement for
non-monetary  exchanges of similar  productive  assets in paragraph 21(b) of APB
Opinion No. 29 "Accounting for Non-monetary  Transactions"  and replaces it with
an exception for exchanges that do not have commercial substance. A non-monetary
exchange  has  commercial  substance  if the future cash flows of the entity are
expected to change  significantly  as a result of the  exchange.  As required by
SFAS 153, the Company  adopted this new  accounting  standard  effective July 1,
2005.  The adoption of SFAS 153 did not have a material  impact on the Company's
financial statements.

      In May 2005,  the FASB issued SFAS No. 154,  Accounting  Changes and Error
Corrections.  SFAS No. 154 establishes retrospective application as the required
method for reporting a change in accounting principle in the absence of explicit
transition requirements specific to the newly adopted accounting principle. SFAS
No. 154 also provides guidance for determining whether retrospective application
is impractical. SFAS No. 154 is effective for accounting changes and corrections
of errors made in fiscal years  beginning  after  December 15, 2005. The Company
does not expect that the adoption of SFAS No. 154 will have a material impact on
its results of operations or financial position.

(m) Research and Development Costs


                                      F-18


      Research and development  related to both future and present  products are
charged to operations as incurred.

(n) Stock Based Compensation

      The Company follows Statement of Financial Accounting Standards (SFAS) No.
123,  "Accounting for Stock-Based  Compensation."  We chose to apply  Accounting
Principal Board Opinion 25 and related  interpretations  in accounting for stock
options granted to the Company's employees.

      The Company provides pro forma  disclosures of compensation  expense under
the fair  market  value  method of SFAS No.  123,  "Accounting  for  Stock-Based
Compensation,"  and SFAS No. 148,  "Accounting  for  Stock-Based  Compensation -
Transition and Disclosure."

The weighted average assumptions used for the years presented are as follows:

      Had compensation  cost for the Company's option plan been determined using
the fair value method at the grant dates,  the effect on the  Company's net loss
and loss per share for the years ended  December 31, 2003,  2004, and 2005 would
have been as follows:

                                      F-19


      For stock  warrants  or options  granted  to  non-employees,  the  Company
measures fair value of the equity instruments utilizing the Black-Scholes method
if  that  value  is  more  reliably  measurable  than  the  fair  value  of  the
consideration  or service  received.  The Company  amortizes  such cost over the
related period of service.

The exercise  price of all stock  warrants  granted was equal to or greater than
the fair market value of the underlying common stock as defined by APB 25 on the
date of the grant.

Stock  compensation  expense in 2004  resulted  from having a limited  number of
shares of Common Stock  authorized  but not issued or reserved for issuance upon
conversion or exercise of outstanding  convertible  and  exercisable  securities
such as debentures,  options and warrants prior to the Company's  annual meeting
of stockholders in September 2003. Prior to the meeting,  to permit consummation
of the sale of the July 2003  Debentures  and the  related  warrants,  the Chief
Executive Officer, Dr. Carter, agreed that he would not exercise his warrants or
options unless and until the Company's  stockholders  approve an increase in the
Company's  authorized  shares of common stock.  For Dr.  Carter's  waiver of his
right to exercise certain options and warrants prior to approval of the increase
in the Company's  authorized shares, the Company agreed to compensate Dr. Carter
and issued Dr. Carter  1,450,000  warrants to purchase common stock at $2.20 per
share in 2003 that  vested in the first  quarter  2004 upon the second ISI asset
closing.  The  Company  recorded  a charge  to  stock  compensation  expense  of
$1,769,000  for the  intrinsic  value of these  warrants in the first quarter of
2004.

(o) Accounts Receivable

Concentration  of credit risk, with respect to accounts  receivable,  is limited
due to the Company's  credit  evaluation  process.  The Company does not require
collateral on its receivables.  The Company's  receivables  primarily consist of
amounts due from  wholesale  drug companies as of December 31, 2004 and 2005 and
all amounts are deemed  collectible.  The Company has  agreements  requiring its
wholesaler  drug  companies to assess credit  worthiness.  The Company  assesses
collectability monthly by review of the accounts receivable aging report.

(p) Deferred Financing Issuance Costs

Deferred  financing  issuance costs  represent  costs incurred by the Company to
issue convertible debt instruments.  The costs are being amortized in accordance
with the interest method of accounting over the terms of the debt.

(q) Convertible Securities with Beneficial Conversion Features

The March 2003,  July 2003,  October 2003,  January 2004 and July 2004 Debenture
issuances and related embedded  conversion  features and warrants issuances were
accounted  for  in  accordance  with  EITF  98-5:   Accounting  for  convertible
securities  with  beneficial  conversion  features  or  contingency   adjustable
conversion  and with EITF No.  00-27:  Application  of issue No. 98-5 to certain
convertible  instruments.  The Company determined the fair values to be ascribed
to detachable  warrants  issued with the  convertible  debentures  utilizing the
Black-Scholes   method.   Discounts  derived  from  determining  the  beneficial
conversion  feature and fair value of the warrants  based on the  relative  fair
value of the proceeds are amortized to financing  costs over the remaining  life
of the debenture in accordance with the effective interest method of accounting.
The  unamortized  discount upon the  conversion of the debentures is expensed to
financing costs on a pro-rata basis.

(4) Inventories

      The Company uses the lower of first-in,  first-out ("FIFO") cost or market
method of accounting for inventory.

Inventories consist of the following:              (in thousands)

(5) Acquisition of Assets of Interferon Sciences, Inc.

      On March 11,  2003,  the Company  acquired  from ISI,  ISI's  inventory of
Alferon N Injection(R)  and a limited license for the  production,  manufacture,
use, marketing and sale of this product. As partial  consideration,  the Company
issued 487,028 shares of its common stock to ISI.  Pursuant to their  agreements
with ISI, the Company  registered  these shares for public sale and ISI reported
that it sold all of these  shares.  The Company also agreed to pay ISI 6% of the
net sales of Alferon N Injection(R).

On March 11, 2003,  the Company also entered into an agreement to purchase  from
ISI all of its rights to the  product  and other  assets  related to the product
including,  but not limited to, real estate and machinery. For these assets, the
Company issued to ISI an additional 487,028 shares and issued 314,465 shares and
267,296  shares,  respectively  to  the  American  National  Red  Cross  and  GP
Strategies Corporation,  two creditors of ISI. The Company guaranteed the market
value of all but 62,500 of these shares to be $1.59 per share on the termination
date. ISI, GP Strategies and the American  National Red Cross reported that they
sold all of their shares.

Pursuant to the acquisition  agreement,  the Company satisfied other liabilities
of ISI which were past due and  secured by a lien on ISI's real  estate and pays
ISI a 6%  royalty  on  the  net  sales  of  products  containing  natural  alpha
interferon.

On May 30, 2003, the Company issued the shares to GP Strategies and the American
National Red Cross.  Pursuant to the Company's agreements with ISI and these two
creditors,  the Company  registered  the foregoing  shares for public sale. As a
result at December 31, 2003 the  guaranteed  value of these  shares  ($491,000),
which had not been sold by these two creditors,  were reclassified to redeemable
common  stock.  At  December  31,  2004,  all  shares had been sold by these two
creditors and the redeemable common stock was reclassified to equity.

On November 6, 2003, the Company acquired and subsequently paid, the outstanding
ISI property tax lien  certificates  in the  aggregate  amount of $457,000  from
certain investors.  These tax liens were issued for property taxes and utilities
due for 2000, 2001 and 2002.

subsequent to the acquisition of specific  securities.  There are two securities
in the less than 12 month category.

The Company has the ability to hold these  securities  until  maturity or market
price  recovery;  therefore,  management  believes  that the  unrealized  losses
represent temporary impairment of the securities.

March 2003 Debentures

      On March 12,  2003,  the Company  issued an  aggregate  of  $5,426,000  in
principal  amount of 6% Senior  Convertible  Debentures  due  January  2005 (the
"March 2003  Debentures")  and an aggregate of 743,288 warrants to two investors
in a private  placement for aggregate gross proceeds of $4,650,000.  Pursuant to
the terms of the March 2003 Debentures, $1,550,000 of the proceeds from the sale
of the March 2003 Debentures was held back and to be released to the Company if,
and only if, the Company  acquired  ISI's  facility with in a set timeframe (see
Note 5 above).  These funds were  released to the Company in July 2003  although
the Company had not acquired ISI's  facility at that time. The Company  recorded
an additional debt discount of $259,000 upon receiving the held back proceeds of
$1,550,000 in July 2003. The March 2003 Debentures were to mature on January 31,
2005 and bore interest at 6% per annum, payable quarterly in cash or, subject to
satisfaction  of certain  conditions,  common stock.  Any shares of common stock
issued to the investors as payment of interest were valued at 95% of the average
closing  price of the common stock  during the five  consecutive  business  days
ending on the third business day immediately  preceding the applicable  interest
payment date. Pursuant to the terms and conditions of the March 2003 Debentures,
the  Company  pledged  all of the  Company's  assets,  other than the  Company's
intellectual  property,  as  collateral  and was subject to comply with  certain
financial  and negative  covenants,  which  included but were not limited to the
repayment of principal  balances upon achieving certain revenue  milestones (see
"Collateral and Financial Covenants" below).

      The March 2003 Debentures were  convertible at the option of the investors
at any time through January 31, 2005 into shares of the Company's  common stock.
The  conversion  price  under the March 2003  Debentures  was fixed at $1.46 per
share, subject to adjustment for anti-dilution protection for issuance of common
stock or securities  convertible  or  exchangeable  into common stock at a price
less than the conversion  price then in effect.  In addition,  in the event that
the Company did pay the redemption price at maturity,  the Debenture holders, at
their  option,  could have  converted  the  balance  due at the lower of (a) the
conversion  price then in effect and (b) 95% of the lowest closing sale price of
the Company's common stock during the three trading days ending on and including
the conversion date.


                                      F-25


      The  investors  also received  detachable  Warrants to acquire at any time
through March 12, 2008 an aggregate of 743,288 shares of common stock at a price
of $1.68 per share (the "March 2008  Warrants").  As of December 31, 2005 all of
these warrants have been exercised.

      Pursuant to the Company's  agreement  with these  investors,  as discussed
below in "Registration  Rights  Agreements"),  the Company registered the shares
issuable upon  conversion of the March 2003  Debentures and upon exercise of the
June 2008 Warrants for public sale.

      The March 2003  Debentures,  were  recorded at a discount on issuance  and
with an  original  issue  discount of  approximately  $2,098,000  and  $776,000,
respectively,  due to ascribing value to the beneficial  conversion  feature and
fair value of warrants based on the relative fair value of the proceeds.

      The conversion option and detachable warrant carry registration rights and
a feature that in certain  circumstances,  deemed in the control of the Company,
could require  partial  settlement of the  conversion  options to be in cash. In
addition the March 2003 Debentures  include other features  including  mandatory
conversion  option and optional  redemption  rights if  contingent  transactions
occur. To determine whether the March 2003 Debentures had embedded  derivatives,
including  the  conversion  option,  that  required  bifurcation  and fair value
accounting,  the Company analyzed the terms of the debentures in accordance with
FASB  Statement No. 133,  "Accounting  for  Derivative  Instruments  and Hedging
Activities"  ("FAS 133"), and EITF 00-19,  "Accounting for Derivative  Financial
Instruments Indexed to, and Potentially Settled in a Company's Own Stock" ("EITF
00-19").  The  Company  concluded  that  bifurcation  was not  required  for the
conversion option and that EITF 00-27: "Application of Issue No. 98-5 to Certain
Convertible  Instruments"  ("EITF 00-27") was the  appropriate  accounting to be
applied.  The  warrants  were  deemed  to be  permanent  equity.  The  mandatory
conversion  option and optional  redemption rights were deemed to be derivatives
requiring  bifurcation and thus the Company obtained a third party valuation for
the aggregate fair value of these  derivatives  that showed the fair value to be
immaterial at inception and for each subsequent reporting period.

      On June 25, 2003,  the Company  issued to each of the March 2003 Debenture
holders  warrants to acquire at any time  through  June 25, 2008 an aggregate of
1,000,000  shares of common  stock at a price of $2.40 per share (the "June 2008
Warrants"). These warrants were issued as incentive for the Debenture holders to
exercise   prior  warrant   issuances   and  were  fair  valued   utilizing  the
Black-Scholes Method at $1,320,000. This issuance, as restated (See Note 2), was
reflected as a deemed  dividend  and a related  increase to  additional  paid in
capital.

      The  investors  exercised  all 743,288 of the March 2008  Warrants in July
2003 which produced gross  proceeds in the amount of  approximately  $1,249,000.
Pursuant to the Company's  agreement  with the Debenture  holders,  as discussed
below in "Registration  Rights  Agreements"),  the Company registered the shares
issuable upon exercise of these June 2008 Warrants for public sale.


                                      F-26


      On May 14, 2004, in  consideration  for the March 2003 Debenture  holders'
exercise of all of the June 2008  Warrants,  the  Company  issued to the holders
warrants (the "May 2009 Warrants") to purchase an aggregate of 1,300,000  shares
of the Company's  common stock.  The Company issued  1,000,000  shares of common
stock and received  gross  proceeds of $2,400,000  from the exercise of the June
2008 Warrants.

      Pursuant to the Company's  agreement with the holders,  as discussed below
in "Registration Rights Agreements",  the Company registered the shares issuable
upon exercise of the May 2009 Warrants for public sale.

      The May 2009  Warrants are to acquire at any time  commencing  on November
14, 2004 through April 30, 2009 an aggregate of 1,300,000 shares of common stock
at a price of $4.50 per share.  This warrant  issuance,  as  restated,  was fair
valued using the Black-Scholes Method, and was reflected as a deemed dividend of
approximately  $2,355,000  during the second quarter of 2004. The exercise price
(and the reset price) under the May 2009 Warrants also is subject to adjustments
for   anti-dilution   protection   similar  to  those  in  the  other  Warrants.
Notwithstanding  the  foregoing,  the  exercise  price as reset or adjusted  for
anti-dilution,  will in no event be less than $4.008 per share.  Upon completion
of the  August  2004  Private  Placement  (see Note 9), the  exercise  price was
lowered to $4.008 per share.  On May 14, 2005,  the exercise  price of these May
2009  Warrants  was set to reset to the  lesser of the  exercise  price  then in
effect or a price equal to the  average of the daily  price of the common  stock
between May 15, 2004 and May 13, 2005;  however,  since the  exercise  price was
previously  set to the floor  price of $4.008 per share this  provision  did not
impact these warrants.

      As of December 31, 2003, the investors had converted the total  $5,426,000
principal of the March 2003  Debentures  into 3,716,438  shares of the Company's
common stock.  Financing costs and interest  expense incurred for the year ended
December  31,  2003,  on the March 2003  Debenture  amounted to  $2,874,000  and
$111,000,  respectively.  The interest due on this debenture was paid in cash of
$17,000  with  $94,000  being paid by the  issuance  of shares of the  Company's
common stock.

July 2003 Debentures

      On July 10,  2003,  the  Company  issued an  aggregate  of  $5,426,000  in
principal  amount of 6% Senior  Convertible  Debentures  due July 31,  2005 (the
"July 2003  Debentures")  and an aggregate of 507,102  Warrants  (the "July 2008
Warrants") in a private placement for aggregate proceeds of $4,650,000.  At this
time, the $1,550,000 of proceeds from the March 2003 Debentures  previously held
back from the Company  was  released to the  Company.  However,  pursuant to the
terms of the July 2003  Debentures,  $1,550,000 of the proceeds from the sale of
the July 2003 Debentures was held back and to be released to the Company if, and
only if, the Company acquired ISI's facility with in a set timeframe (see Note 5
above).  These funds were  released to the Company in October 2003  although the
Company had not acquired ISI's  facility at that time.  The Company  recorded an
additional  debt discount of $259,000  upon  receiving the held back proceeds of
$1,550,000 in October 2003. The July 2003  Debentures were to mature on July 31,
2005 and bore interest at 6% per annum, payable quarterly in cash or, subject to
satisfaction  of certain  conditions,  common stock.  Any shares of common stock
issued to the investors as payment of interest were valued at 95% of the average
closing  price of the common stock  during the five  consecutive  business  days
ending on the third business day immediately  preceding the applicable  interest
payment date.  Pursuant to the terms and conditions of the July 2003 Debentures,
the  Company  pledged  all of the  Company's  assets,  other than the  Company's
intellectual  property,  as  collateral  and was subject to comply with  certain
financial  and negative  covenants,  which  included but were not limited to the
repayment of principal  balances upon achieving certain revenue  milestones (see
"Collateral and Financial Covenants" below).


                                      F-27


      The July 2003 Debentures  were  convertible at the option of the investors
at any time through July 31, 2005 into shares of the Company's common stock. The
conversion  price under the July 2003  Debentures  was fixed at $2.14 per share;
however,  as part of the subsequent  debenture  placement  closed on October 29,
2003 (see  below),  the  conversion  price  under the July 2003  Debentures  was
lowered to $1.89 per share.  The conversion  price was subject to adjustment for
anti-dilution  protection for issuance of common stock or securities convertible
or exchangeable into common stock at a price less than the conversion price then
in effect.  In  addition,  in the event that the Company did pay the  redemption
price at maturity,  the Debenture holders, at their option, could have converted
the balance due at the lower of (a) the conversion  price then in effect and (b)
95% of the lowest  closing sale price of the  Company's  common stock during the
three  trading days ending on and including the  conversion  date. In 2003,  the
Company recorded a debt discount of  approximately  $741,000 upon the conversion
price reset to $1.89 per share.  The additional  debt discount is amortized over
the remaining life of these Debenture or, in the event of a conversion,  written
off to financing costs on a pro-rata basis.

      The July  2008  Warrants  received  by the  investors,  as  amended,  were
exercisable  for an  aggregate  of 507,102  shares of common stock at a price of
$2.46 per share.  These Warrants,  as amended,  did not result in any additional
debt.  These  Warrants were exercised in July 2004 which produced gross proceeds
in the amount of $1,247,000.

      Pursuant to the Company's  agreement with the holders,  as discussed below
in "Registration Rights Agreements",  the Company registered the shares issuable
upon  conversion of the July 2003  Debentures and upon exercise of the July 2008
Warrants for public sale.

      The July 2003  Debentures were recorded at a discount on issuance and with
an  original   issue   discount  of   approximately   $2,280,000  and  $517,000,
respectively,  due to ascribing value to the beneficial  conversion  feature and
fair value of warrants based on the relative fair value of the proceeds.

      The conversion option and detachable warrant carry registration rights and
a feature that in certain  circumstances,  deemed in the control of the Company,
could require  partial  settlement of the  conversion  options to be in cash. In
addition,  the July 2003 Debentures include other features  including  mandatory
conversion  option and optional  redemption  rights if  contingent  transactions
occur. To determine  whether the July 2003 Debentures had embedded  derivatives,
including  the  conversion  option,  that  required  bifurcation  and fair value
accounting,  the Company analyzed the terms of the debentures in accordance with
FASB  Statement No. 133,  "Accounting  for  Derivative  Instruments  and Hedging
Activities"  ("FAS 133"), and EITF 00-19,  "Accounting for Derivative  Financial
Instruments Indexed to, and Potentially Settled in a Company's Own Stock" ("EITF
00-19").  The  Company  concluded  that  bifurcation  was not  required  for the
conversion option and that EITF 00-27: "Application of Issue No. 98-5 to Certain
Convertible  Instruments"  ("EITF 00-27") was the  appropriate  accounting to be
applied.  The  warrants  were  deemed  to be  permanent  equity.  The  mandatory
conversion  option and optional  redemption rights were deemed to be derivatives
requiring  bifurcation and thus the Company obtained a third party valuation for
the aggregate fair value of these  derivatives  that showed the fair value to be
immaterial at inception and for each subsequent reporting period.


                                      F-28


      During  2003,  the  investors  had  converted   approximately   $1,169,000
principal  of the July 2003  debentures  into  618,478  shares of the  Company's
common stock. During 2004, the investors had converted  $4,257,071  principal of
the July 2003 debentures into 2,252,417 shares of the Company's common stock. As
of December 31, 2004, the investors had converted the total $5,426,000 principal
of the July 2003 Debentures into 2,870,900 shares of common stock.

      The Company recorded financing costs for the years ended December 31, 2004
and 2003,  with regard to the July 2003 Debentures of $2,301,000 and $1,496,000,
respectively.  Interest  incurred for the years ended December 31, 2003 and 2004
was $117,000 and $3,000, respectively.

October 2003 Debentures

      On October 29, 2003,  the Company  issued an aggregate  of  $4,142,357  in
principal amount of 6% Senior  Convertible  Debentures due October 31, 2005 (the
"October 2003  Debentures")  and an aggregate of 410,134  Warrants (the "October
2008  Warrants")  in  a  private  placement  for  aggregate  gross  proceeds  of
$3,550,000. Pursuant to the terms of the October 2003 Debentures,  $1,550,000 of
the  proceeds  from the sale of the October 2003  Debentures  were held back and
were to be released to the Company if, and only if, the Company  acquired  ISI's
facility  within 90 days of January  26,  2004 and  provided  a mortgage  on the
facility as further security for the October 2003 Debentures (see Note 5 above).
In April 2004,  the Company  acquired the facility and the Company  subsequently
provided  the mortgage of the  facility to the  Debenture  holders and the above
funds were  released.  The  Company  recorded  an  additional  debt  discount of
$259,000 upon receiving  these held back proceeds.  The October 2003  Debentures
were to mature on October  31, 2005 and bore  interest at 6% per annum,  payable
quarterly in cash or,  subject to  satisfaction  of certain  conditions,  common
stock. Any shares of common stock issued to the investors as payment of interest
are to be valued at 95% of the average  closing price of the common stock during
the five consecutive  business days ending on the third business day immediately
preceding  the  applicable  interest  payment  date.  Pursuant  to the terms and
conditions  of the  October  2003  Debentures,  the  Company  pledged all of the
Company's assets, other than the Company's  intellectual property, as collateral
and was subject to comply with certain financial and negative  covenants,  which
included  but were not  limited to the  repayment  of  principal  balances  upon
achieving certain revenue  milestones (see "Collateral and Financial  Covenants"
below).

      The October 2003 Debentures are convertible at the option of the investors
at any time through October 31, 2005 into shares of the Company's  common stock.
The  conversion  price under the October 2003  Debentures  is fixed at $2.02 per
share, subject to adjustment for anti-dilution protection for issuance of common
stock or securities  convertible  or  exchangeable  into common stock at a price
less than the conversion  price then in effect.  In addition,  in the event that
the  Company  does not pay the  redemption  price  at  maturity,  the  Debenture
holders,  at their  option,  may convert the balance due at the lower of (a) the
conversion  price then in effect and (b) 95% of the lowest closing sale price of
the Company's common stock during the three trading days ending on and including
the conversion date.

      The October 2008 Warrants,  as amended,  received by the investors were to
acquire an aggregate  of 410,134  shares of common stock at a price of $2.32 per
share.  These Warrants were exercised in July 2004 which produced gross proceeds
in the amount of approximately $952,000.


                                      F-29


      Pursuant to the Company's  agreement with the holders,  as discussed below
in "Registration Rights Agreements",  the Company registered the shares issuable
upon  conversion of the October 2003 Debentures and upon exercise of the October
2008 Warrants for public sale.

      The October 2003  Debentures  were  recorded at a discount on issuance and
with an original issue discount of $2,000,000 and $333,000, respectively, due to
ascribing value to the beneficial  conversion feature and fair value of warrants
based on the relative fair value of the proceeds.

      The conversion option and detachable warrant carry registration rights and
a feature that in certain  circumstances,  deemed in the control of the Company,
could require  partial  settlement of the  conversion  options to be in cash. In
addition, the October 2003 Debentures include other features including mandatory
conversion  option and optional  redemption  rights if  contingent  transactions
occur.   To  determine   whether  the  October  2003   Debentures  had  embedded
derivatives, including the conversion option, that required bifurcation and fair
value accounting, the Company analyzed the terms of the debentures in accordance
with FASB Statement No. 133, "Accounting for Derivative  Instruments and Hedging
Activities"  ("FAS 133"), and EITF 00-19,  "Accounting for Derivative  Financial
Instruments Indexed to, and Potentially Settled in a Company's Own Stock" ("EITF
00-19").  The  Company  concluded  that  bifurcation  was not  required  for the
conversion option and that EITF 00-27: "Application of Issue No. 98-5 to Certain
Convertible  Instruments"  ("EITF 00-27") was the  appropriate  accounting to be
applied.  The  warrants  were  deemed  to be  permanent  equity.  The  mandatory
conversion  option and optional  redemption rights were deemed to be derivatives
requiring  bifurcation and thus the Company obtained a third party valuation for
the aggregate fair value of these  derivatives  that showed the fair value to be
immaterial at inception and for each subsequent reporting period.

      In October 2005, the Company entered into an amendment  agreement with the
October 2003 Debenture  holders to amend the maturity date from October 31, 2005
to June 30, 2007,  and increase the interest rate from 6% to 7% (see  "Debenture
Agreement Amendment" below for more details).

      On July 13, 2004, in consideration for the Debenture  holders' exercise of
all of the July 2003  ("July 2008  Warrants")  and  October  2003("October  2008
Warrants") Warrants amounting to approximately $2,199,000 in gross proceeds, the
Company issued to these holders  warrants (the "June 2009 Warrants") to purchase
an aggregate of 1,300,000  shares of common stock.  The Company recorded charges
associated with the issuance of these warrants,  as restated,  fair valued using
the Black-Scholes  Method,  at $1,676,000,  which has been reflected as a deemed
dividend.

      Pursuant to the Company's  agreement with the holders,  as discussed below
in "Registration Rights Agreements",  the Company registered the shares issuable
upon exercise of these Warrants for public sale.

      The June 2009  Warrants are to acquire at any time  commencing  on January
13, 2005 through June 30, 2009 an aggregate of 1,300,000  shares of common stock
at a price of $3.75 per share.  On July 13, 2005,  the  exercise  price of these
June 2009 Warrants was reset to $3.33,  the lesser of the exercise price then in
effect or a price equal to the  average of the daily  price of the common  stock
between  July 14,  2004 and July 12,  2005.  The  exercise  price (and the reset
price)  under  the  June  2009  Warrants  also is  subject  to  adjustments  for
anti-dilution protection similar to those in the other Warrants. Notwithstanding
the foregoing,  the exercise price as reset or adjusted for anti-dilution,  will
in no event be less than $3.33 per share.  Upon  completion  of the August  2004
Private  Placement  (see  below),  the  exercise  price was lowered to $3.33 per
share.  The Company agreed to register the shares  issuable upon exercise of the
June 2009 Warrants  pursuant to substantially the same terms as the registration
rights  agreements  between  the  Company  and  the  holders.  Pursuant  to this
obligation, the Company has registered the shares.


                                      F-30


      The Company has paid $1,300,000 into the debenture cash collateral account
as required  by the terms of the  October  2003  Debentures.  The  amounts  paid
through December 31, 2005 have been accounted for as advances receivable and are
reflected as such on the accompanying balance sheet as of December 31, 2005. The
cash  collateral   account  provides  partial  security  for  repayment  of  the
outstanding  principal  and accrued  interest on the  Debentures in the event of
default.

      As of December 31, 2005, the investors had converted  $2,071,178 principal
amount of the October 2003 Debenture into 1,025,336  shares of Common Stock. The
remaining  balance of $2,071,178 is convertible  into 1,025,336 shares of common
stock.

      The Company  recorded  financing  costs for the years ended  December  31,
2003,  2004 and 2005,  with regard to the October 2003  Debentures  of $361,000,
$1,366,000  and  $865,000,  respectively.  Interest  expense for the years ended
December 31, 2005, 2004 and 2003, with regard to the October 2003 Debentures was
$129,000, $118,000 and $24,000, respectively.

January 2004 Debentures

      On January 26, 2004,  the Company  issued an aggregate  of  $4,000,000  in
principal amount of 6% Senior  Convertible  Debentures due January 31, 2006 (the
"January  2004  Debentures"),  an aggregate of 790,514  warrants (the "July 2009
Warrants") and 158,104 shares of common stock, and Additional  Investment Rights
(to purchase up to an  additional  $2,000,000  principal  amount of January 2004
Debentures  commencing  in six months) in a private  placement for aggregate net
proceeds of $3,695,000.  The January 2004  Debentures  were to mature on January
31,  2006 and bear  interest  at 6% per  annum,  payable  quarterly  in cash or,
subject to satisfaction of certain conditions, common stock. As discussed below,
the maturity  date and interest  rate were  amended.  Any shares of common stock
issued to the  investors  as payment of  interest  shall be valued at 95% of the
average closing price of the common stock during the five  consecutive  business
days ending on the third  business  day  immediately  preceding  the  applicable
interest  payment  date.  Pursuant to the terms of the January 2004  Debentures,
commencing  July 26,  2004,  the  Company  began to repay  the then  outstanding
principal amount under the Debentures in monthly installments  amortized over 18
months in cash or, at the  Company's  option,  in  shares of common  stock.  Any
shares of common stock issued to the investors as installment  payments shall be
valued at 95% of the average closing price of the common stock during the 10-day
trading period  commencing on and including the eleventh trading day immediately
preceding  the date  that the  installment  is due.  Pursuant  to the  terms and
conditions  of the  January  2004  Debentures,  the  Company  pledged all of the
Company's assets, other than the Company's  intellectual property, as collateral
and was subject to comply with certain financial and negative  covenants,  which
included  but were not  limited to the  repayment  of  principal  balances  upon
achieving certain revenue  milestones (see "Collateral and Financial  Covenants"
below).


                                      F-31


      The January 2004 Debentures are convertible at the option of the investors
at any time through January 31, 2006 into shares of the Company's  common stock.
The  conversion  price under the January 2004  Debentures was fixed at $2.53 per
share, subject to adjustment for anti-dilution protection for issuance of common
stock or securities  convertible  or  exchangeable  into common stock at a price
less than the conversion  price then in effect.  In addition,  in the event that
the  Company  does not pay the  redemption  price  at  maturity,  the  Debenture
holders,  at their  option,  may convert the balance due at the lower of (a) the
conversion  price then in effect and (b) 95% of the lowest closing sale price of
the Company's common stock during the three trading days ending on and including
the conversion  date. Upon completion of the August 2004 Private  Placement (see
Note 9),  the  conversion  price was  lowered to $2.08 per  share.  The  Company
recorded an additional debt discount as restated (see Note 2), of  approximately
$915,000 due to this conversion price reset.

      In October 2005, the Company entered into an amendment  agreement with the
January 2004 Debenture  holders to amend the maturity date from October 31, 2005
to June 30, 2007,  and increase the interest rate from 6% to 7% (see  "Debenture
Agreement Amendment" below for more details).

      There are two classes of July 2009  Warrants  received  by the  Investors:
Class A and Class B. The Class A warrants  are to acquire any time from July 26,
2004 through July 26, 2009 an aggregate of up to 395,257  shares of common stock
at a price of $3.29 per share. The Class B warrants are to acquire any time from
July 26, 2004  through  July 26, 2009 an  aggregate  of up to 395,257  shares of
common stock at a price of $5.06 per share.  On January 27,  2005,  the exercise
price of these July 2009  Class A and Class B Warrants  were reset to the lesser
of their  respective  exercise  price  then in  effect  or a price  equal to the
average of the daily  price of the common  stock  between  January  27, 2004 and
January 26, 2005.  The exercise  price (and the reset price) under the July 2009
Warrants also is subject to similar  adjustments for  anti-dilution  protection.
Notwithstanding  the  foregoing,  the  exercise  prices as reset or adjusted for
anti-dilution, will in no event be less than $2.58 per share. Upon completion of
the August 2004 Private  Placement  (see Note 9), the exercise price was lowered
to $2.58 per share.

      Pursuant to the Company's  agreement  with these  investors,  as discussed
below in "Registration  Rights  Agreements"),  the Company registered the shares
issuable upon conversion of the January 2004 Debentures and upon exercise of the
July 2009 Warrants for public sale.

      The January 2004  Debentures  were  recorded at a discount on issuance and
with an original issue discount of $306,000 and $465,000,  respectively,  due to
ascribing value to the beneficial  conversion feature and fair value of warrants
based on the relative fair value of the proceeds.

      The conversion option and detachable warrant carry registration rights and
a feature that in certain  circumstances,  deemed in the control of the Company,
could require  partial  settlement of the  conversion  options to be in cash. In
addition, the January 2004 Debentures include other features including mandatory
conversion  option and optional  redemption  rights if  contingent  transactions
occur.   To  determine   whether  the  January  2004   Debentures  had  embedded
derivatives, including the conversion option, that required bifurcation and fair
value accounting, the Company analyzed the terms of the debentures in accordance
with FASB Statement No. 133, "Accounting for Derivative  Instruments and Hedging
Activities"  ("FAS 133"), and EITF 00-19,  "Accounting for Derivative  Financial
Instruments  Indexed to, and Potentially Settled in a Company's Own Stock" (EITF
"00-19").  The Company  concluded  that  bifurcation  was not  required  for the
conversion option and that EITF 00-27: "Application of Issue No. 98-5 to Certain
Convertible  Instruments"  ("EITF 00-27") was the  appropriate  accounting to be
applied.  The  warrants  were  deemed  to be  permanent  equity.  The  mandatory
conversion  option and optional  redemption rights were deemed to be derivatives
requiring  bifurcation and thus the Company obtained a third party valuation for
the aggregate fair value of these  derivatives  that showed the fair value to be
immaterial at inception and for each subsequent reporting period.


                                      F-32


Section 713 of the American Stock Exchange Company Guide

      Section 713 of the American Stock Exchange ("AMEX") Company Guide provides
that the Company must obtain  stockholder  approval before issuance,  at a price
per share below market value,  of common stock, or securities  convertible  into
common  stock,  equal to 20% or more of the Company's  outstanding  common stock
(the "Exchange  Cap").  The Debentures and Warrants have provisions that require
the  Company  to pay  cash in lieu of  issuing  shares  upon  conversion  of the
Debentures or exercise of the Warrants if the Company is prevented  from issuing
such shares  because of the Exchange  Cap. In May 2004,  the  Debenture  holders
agreed to amend the  provisions  of these  Debentures  and Warrants to limit the
maximum  amount of funds that the holders  could  receive in lieu of shares upon
conversion of the Debentures  and/or  exercise of the Warrants in the event that
the Exchange Cap was reached to 119.9% of the  conversion  price of the relevant
Debentures and 19.9% of the relevant  Warrant  exercise price. See below for the
accounting effect on this matter.

      Taken  separately,  the March,  July,  October and January 2004  debenture
transactions  do not trigger  Section 713.  However,  the AMEX took the position
that these transactions should be aggregated and, as such,  stockholder approval
was required  for the  issuance of common  stock for a portion of the  potential
exercise of the warrants and conversion of the Debentures in connection with the
January 2004  Debentures.  The amount of potential shares that the Company could
exceed the Exchange Cap amounted to approximately  1,299,000. In accordance with
EITF 00-19,  Accounting  For  Derivative  Financial  Instruments  Indexed to and
Potentially  Settled in a Company's Own Stock,  the Company  recorded on January
26, 2004, a redemption obligation of approximately $2,160,000, as restated, with
a  corresponding  increase to debt discount to be amortized over the life of the
debt or until the Company obtains shareholder  approval.  Any remaining discount
would be reclassed to additional paid in capital.

      In addition,  in  accordance  with EITF 00-19,  the Company  revalued this
redemption obligation as of March 31, 2004. The Company increased the redemption
obligation and recorded  additional  finance charge of $1,024,000 as a result of
this  revaluation.  The Company  also  incurred  $104,000 in  financing  charges
related to the  amortization of the related discount during the first quarter of
2004.

      Stockholder  approval  was  obtained at the  Company's  Annual  Meeting of
Stockholders  on June 23,  2004.  In  accordance  with EITF  00-19,  the Company
revalued this redemption  obligation  associated with the 1,299,000 shares as of
June 23, 2004 (date of shareholder  approval).  The Company recorded a reduction
in the value of the redemption  obligation and financing charge of $839,000 as a
result of this  revaluation and additional  financing charge of $242,000 related
to the  amortization  of the  debt  discount  in the  second  quarter  2004.  In
addition,  upon receiving the requisite  stockholder  approval on June 23, 2004,
the  redemption  obligation of $2,345,000  and the  remaining  unamortized  debt
discount of $1,815,000 were reclassified as additional paid in capital.


                                      F-33


      During  2004,  the  investors  made  installment  payments of $777,000 and
converted  $139,150 of  principal  amount of the  January  2004  debenture  into
358,932  and 55,000  shares of common  stock,  respectively.  During  2005,  the
investors   had  made   installment   payments  of   $1,111,111   and  converted
approximately  $608,000  principal  amount of the January 2004  Debentures  into
735,217  and  292,000  shares  of  common  stock,  respectively.  The  remaining
principal on these Debentures was $1,364,602 as of December 31, 2005.

      The Company recorded financing costs for the years ended December 31, 2004
and 2005 with regard to the January 2004  Debentures  of $720,000 and  $917,000,
respectively.  Interest  expense for the years ended December 31, 2005 and 2004,
with  regard  to  the  January  2004   Debentures  was  $145,000  and  $207,000,
respectively.

July 2004 Debentures

      Pursuant to the Additional Investment Rights issued in connection with the
January 2004  Debentures,  the Company  issued to the  investors  an  additional
$2,000,000   principal  amount  of  January  2004  Debentures  (the  "July  2004
Debentures").  The July  2004  Debentures  are  identical  to the  January  2004
Debentures  except that the conversion price is $2.58.  The investors  exercised
the Additional  Investment  Rights on July 13, 2004 and the Company received net
proceeds of  $1,860,000.  Upon  completion of the August 2004 Private  Placement
(see Note 9), the  conversion  price of the July 2004  Debentures was lowered to
$2.08  per  share.   The  Company   recorded  an  additional  debt  discount  of
approximately $632,000 upon the conversion price reset to $2.08 per share, which
is being  amortized over the remaining life of the debenture in accordance  with
the effective interest method of accounting.

      The July 2004  Debentures  were  recorded  at a discount  on  issuance  of
$628,000 due to ascribing  value to the beneficial  conversion  feature and fair
value of warrants based on the relative fair value of the proceeds.

      The conversion option and detachable warrant carry registration rights and
a feature that in certain  circumstances,  deemed in the control of the Company,
could require  partial  settlement of the  conversion  options to be in cash. In
addition,  the July 2004 Debentures include other features  including  mandatory
conversion  option and optional  redemption  rights if  contingent  transactions
occur. To determine  whether the July 2004 Debentures had embedded  derivatives,
including  the  conversion  option,  that  required  bifurcation  and fair value
accounting,  the Company analyzed the terms of the debentures in accordance with
FASB  Statement No. 133,  "Accounting  for  Derivative  Instruments  and Hedging
Activities"  ("FAS 133"), and EITF 00-19,  "Accounting for Derivative  Financial
Instruments  Indexed to, and Potentially Settled in a Company's Own Stock" (EITF
00-19").  The  Company  concluded  that  bifurcation  was not  required  for the
conversion option and that EITF 00-27: "Application of Issue No. 98-5 to Certain
Convertible  Instruments"  ("EITF 00-27") was the  appropriate  accounting to be
applied.  The  warrants  were  deemed  to be  permanent  equity.  The  mandatory
conversion  option and optional  redemption rights were deemed to be derivatives
requiring  bifurcation and thus the Company obtained a third party valuation for
the aggregate fair value of these  derivatives  that showed the fair value to be
immaterial at inception and for each subsequent reporting period.


                                      F-34


      In October 2005, the Company entered into an amendment  agreement with the
July 2004 Debenture  holders to amend the maturity date from October 31, 2005 to
June 30, 2007,  and increase  the  interest  rate from 6% to 7% (see  "Debenture
Agreement Amendment" below for more details).

      As of December 31, 2005, the Company made installment payments of $500,000
resulting in the issuance of 331,669 shares of the Company's  common stock.  The
Debenture holders had not converted any portion of this debenture as of December
31, 2005.

      The Company recorded financing costs for the years ended December 31, 2005
and 2004 with  regard to the July 2004  Debentures  of  $481,000  and  $248,000,
respectively.  Interest  expense for the years ended December 31, 2005 and 2004,
with  regard  to  the  January  2004   Debentures   was  $113,000  and  $61,000,
respectively.

Debenture Agreement Amendment

      On  October 6,  2005,  the  Company  entered  into a  material  definitive
agreement with the October 2003, January 2004 and July 2004 debenture holders to
1) amend the remaining outstanding Debentures that were to mature on October 31,
2005 (as  amended,  the  "October  2003  Debenture")  and the two  traunches  of
outstanding   debentures  due  to  mature  on  January  31,  2006  (as  amended,
respectively,  the "January 2004 and July 2004 Debentures"),  to a maturity date
of June 30, 2007,  2) to increase the interest  rate from 6% per annum to 7% per
annum.  In  consideration  for extending  the maturity  date of the  outstanding
debentures,  the Company  issued an aggregate of 225,000  Warrants (the "October
2009  Warrants") to the debenture  holders to acquire common stock at a price of
$2.50 per share at any time from October 31, 2005 through  October 31, 2009. The
October 2009 Warrants  contain  provisions for adjustment of the exercised price
in the event of certain  anti-dilution  events.  The Company  agreed to register
135% of the shares  issuable  as interest  shares  that might  result due to the
amendments  to the  Debentures  and issuable  upon  exercise of the October 2009
Warrants.

      In accordance with EITF 96-19,  "Debtor's Accounting for a Modification or
Exchange  of Debt  Instruments",  the Company has treated the change in terms to
the original  debentures as non-substantial in nature and have not accounted for
such modification as an extinguishment of debt, but rather a debt  modification.
In  addition,   the  225,000  warrants  issued  to  the  debenture   holders  as
consideration   for   extending   the  maturity   date  were  valued  using  the
Black-Scholes  method and $189,000 of additional  debt discount on the July 2004
Debenture was recorded.  The discount will be amortized as interest expense over
the new term of the debt instrument in accordance with the effective interest of
accounting. Any costs incurred by third parties were expensed as incurred.

Registration Rights Agreements

      The Company entered into Registration Rights Agreements with the investors
in connection with the issuance of (i) the above Debentures; (ii) the June 2008,
July 2008,  October 2008,  July 2009, and May 2009 Warrants  (collectively,  the
"Warrants");  and (iii) the  shares  issued in  January  2004.  Pursuant  to the
Registration  Rights  Agreements  the  Company has  registered  on behalf of the
investors  the  shares  issued to them in  January  2004 and 135% of the  shares
issuable  upon  conversion  of the  Debentures  and upon  exercise of all of the
Warrants.  If, subject to certain exceptions,  sales of all shares so registered
cannot be made pursuant to the registration statements, then the Company will be
required  to pay to the  investors  their pro rata  share of  $.00067  times the
outstanding  principal amount of the relevant  Debentures for each day the above
condition exists as liquidated  damages.  As a result of the Company's inability
to timely file its annual  report on Form 10-K for the year ended  December  31,
2005, the Company currently is subject to liquidated  damages until such time as
the  Shares  are again  registered  for  public  resale or  eligible  for resale
pursuant to Rule  144(k)  under the  Securities  Act.  (See Note 20-  subsequent
events for more information on liquidated damages).

Investment Banking Fees

      By agreement with Cardinal Securities, LLC, for general financial advisory
services and in conjunction  with the private  debenture  placements in July and
October 2003 and in January and July 2004, the Company paid Cardinal Securities,
LLC an  investment  banking  fee  equal  to 7% of the  investments  made  by the
Debenture  holders and issued to  Cardinal  the  following  warrants to purchase
common  stock:  (i)  112,500   exercisable  at  $2.57  per  share;  (ii)  87,500
exercisable  at $2.42 per  share;  and (iii)  100,000  exercisable  at $3.04 per
share.  The $2.57 warrants expire on July 10, 2008, the $2.42 warrants expire on
October 29, 2008 and the $3.04 warrants  expire on January 5, 2009.  With regard
to the exercise of the June 2008 Warrants and issuance of the May 2009 Warrants,
Cardinal  received  an  investment  banking  fee of 7%, half in cash and half in
shares.  With regard to the exercise of the Additional  Investment  Rights,  the
July 2008 and October  2008  Warrants  and  issuance of the July 2009  Warrants,
Cardinal  received an investment  banking fee of 7%, $146,980 in cash and 22,703
in shares as well as 50,000  warrants  exercisable at $4.07 expiring on July 12,
2009.  By  agreement  with  Cardinal,  the  Company  has  registered  all of the
foregoing  shares and  shares  issuable  upon  exercise  of the above  mentioned
warrants for public resale. As a result of the transactions discussed above, the
Company recorded $538,000 and $149,000, as restated, as deferred financing costs
on the balance  sheet as of December  31,  2003 and 2004,  respectively,  with a
related  increase to additional paid in capital.  These costs are amortized over
the life of the  debenture.  Amortization  expense was  $360,000,  $263,000  and
$161,000 as of December 31, 2003, 2004 and 2005.

Conversion of Convertible Debt

The maximum number of shares issuable upon debt conversion,  including  interest
as well as 135% of the shares  issuable upon  conversion  and interest  payments
were 5,011,525 and 3,667,662 shares at December 31, 2004 and 2005, respectively.

Collateral and Financial Covenants

      The Company paid  $1,300,000  in 2003 into the debenture  cash  collateral
account  held by the  debenture  holders as required by the terms of the October
2003 Debentures. The amounts paid have been accounted for as advances receivable
and are reflected as such on the  accompanying  balance sheet as of December 31,
2005. The cash collateral account provides partial security for repayment of the
outstanding Debentures in the event of default.

      Pursuant to the terms and conditions of all of the outstanding Debentures,
the Company has pledged all of the  Company's  assets,  other than the Company's
intellectual property, as collateral,  and the Company is subject to comply with
certain financial covenants. The Company failed to timely file its Annual Report
on Form 10-K with the  Securities and Exchange  Commission  pursuant to the 1934
Act, and therefore, was in violation of its covenant to timely file. See Note 20
-  Subsequent  Events for more  details on this and the  Company's  receipt of a
waiver of this covenant.


                                      F-36

the  Common  Stock to be listed on the AMEX for more  than an  aggregate  of ten
trading days in any 365-day period;  (c) Any money judgment,  writ or warrant of

or warranties in the  Debentures  and the related  documents  (the  "Transaction
Documents") or any mortgage are untrue in any material respect when made and are
not cured, provided they are curable,  within a specified period and such breach
of  representations  and warranties  would have a material adverse effect on the
Company  or  materially  impair  the  ability  of the  Company  to  satisfy  its
obligations  to the Holders;  (f) the Company fails to perform or observe in any
material  respect  any  material  covenant  in the  Debenture  or  any  relevant
Transaction  Document (such as the failure to honor any conversion notice);  (g)
the Company  becomes  insolvent or certain other events that trigger  creditors'
rights,  bankruptcy,  liquidation or similar  proceedings occur; (h) the Company

Collateral  Account  Bank  shall  fail to  comply  with any of the  terms of the
Account  Control  Agreement;  (l) at any time  required  to be in full force and
effect,  the  Letters  of Credit  ceases to be in full force and effect and such
breach is not cured  within a specified  time;  (m) the report of the  Company's
auditors on the Company's consolidated audited financial statements for the year
ended  prior to the  issuance  of the  relevant  Debenture  contained  any going
concern  qualification;  or (n) any  material  damage  to,  or  loss,  theft  or
destruction of, any Collateral,  or any adverse event such as a labor dispute or
act of God, which causes,  for more than 15  consecutive  days, the cessation or
substantial curtailment of revenue producing activities at any material facility
of the Company or any of its  Subsidiaries.  Upon the  occurrence of an Event of
Default described in subsection (g) above, the Debentures  become  automatically
due and payable. In such event the Debentures are to be redeemed at a redemption
price equal to 100% of the outstanding principal amount, plus accrued and unpaid
interest thereon.  In addition,  upon an Event of Default,  the interest rate on
the Debentures  permanently  increases by two percent and, solely in the case of
an Event of Default triggered by a conversion  failure ((f) above),  higher, but
in no event can the interest rate increase above the lower of 20% or the highest
rate permitted by applicable law (See Note 20).


                                      F-37


      In connection with the Debenture  agreements,  the Company has outstanding
letters of credit of $1 million as additional collateral.

(9) Stockholders' Equity

(a) Preferred Stock

      The  Company is  authorized  to issue  5,000,000  shares of $.01 par value
preferred  stock  with  such  designations,  rights  and  preferences  as may be
determined by the board of directors.  There were no preferred shares issued and
outstanding at December 31, 2004 and 2005.

(b) Common Stock

      On July 31, 2003,  we had  approximately  104,000  shares of the Company's
$.001 authorized  shares of $.001 par value Common Stock that were not issued or
reserved for issuance.  In order to  accommodate  the shares needed for the July
2003 Debenture,  Dr. Carter,  the Company's Chief Executive Officer and Cardinal
Capital,  LLC, the placement  agent,  agreed that they would not exercise  their
warrants  or options  unless and until the  Company's  stockholders  approved an
increase in the Company's  authorized  shares of common stock. This action freed
up 3,206,650  shares.  For Dr. Carter's waiver of his right to exercise  certain
options  and  warrants  prior  to  approval  of the  increase  in the  Company's
authorized  shares,  the Company  agreed to compensate Dr. Carter and issued Dr.
Carter  1,450,000  warrants to purchase  common stock at $2.20 per share in 2003
that vested in the first  quarter  2004 upon the second ISI asset  closing.  The
Company recorded a charge to stock compensation expense during the first quarter
of 2004 of $1,769,000 upon the full vesting of these warrants at their intrinsic
value.

      The  Company's   stockholders  approved  an  amendment  to  the  Company's
corporate charter at the Annual Shareholder meeting held in Philadelphia,  PA on
September 10, 2003.  This amendment  increased the Company's  authorized  shares
from 50,000,000 to 100,000,000.

      As of December 31, 2004 and 2005, 49,631,766 and 56,264,155 shares, net of
shares held in the treasury, were outstanding, respectively.

(c)  Minority Shareholder Interest

      On March 20, 2002 the Company's European Subsidiary  Hemispherx  Biopharma
Europe,  S.A.  ("Hemispherx,  S.A.")  entered  into  a  Sales  and  Distribution
agreement with Laboratorios del Dr. Esteve S.A. ("Esteve")(Note 17). Pursuant to
the terms of the  Agreement,  Esteve was granted the  exclusive  right to market
Ampligen(R)  in  Spain,  Portugal  and  Andorra  for the  treatment  of  Myalgic
Encephalitis/Chronic Fatigue Syndrome ("ME/CFS"). In addition to other terms and
other  projected  payments,  Esteve  paid an initial and non  refundable  fee of
625,000 Euros  (approximately  $563,000) to Hemispherx S.A. on April 24, 2002 as
the first part of a series of milestone based payments.


                                      F-38


      During  March  2002,  Hemispherx,  S.A.  was  authorized  to  issue  up to
22,000,000 Euros of seven percent (7%) convertible  preferred  securities.  Such
securities  are  guaranteed  by the parent  company and are  convertible  into a
specified  number  of shares  of  Hemispherx  S.A.  pursuant  to the  securities
agreement.  Conversion is to occur on the earlier of an initial public  offering
of Hemispherx S.A. on a European stock exchange or September 30, 2003.

      Esteve  purchased  1,000,000 Euros of Hemispherx  Biopharma  Europe S.A.'s
convertible  preferred  equity  certificates  on May 23, 2002.  During 2002, the
terms and conditions of these  securities  were changed so that these  preferred
equity  certificates  could be  converted  into the common  stock of  Hemispherx
Biopharma,  Inc. in the event that a European IPO was not completed by September
30, 2003. The  conversion  rate was 300 shares of Hemispherx  Biopharma,  Inc.'s
common shares for each 1,000 Euro convertible preferred certificate. As a result
the Company recorded  approximately  $946,000 as minority interest in subsidiary
on its balance sheet at December 31, 2002.

      On December 18, 2002,  we proposed that Esteve  convert their  convertible
preferred equity certificates into Hemispherx common stock pursuant to the terms
of the agreement and all unpaid dividends at the market price on that conversion
date.  On  January  9, 2003,  Esteve  accepted  the  Company's  proposal  and we
registered these shares for public sale.

      On March 13, 2003, we issued 347,445 shares of the Company's  common stock
to Provesan  S.A., an affiliate of Esteve S.A., in exchange for 1,000,000  Euros
of convertible  preferred  equity  certificates and any unpaid  dividends.  As a
result of the exchange,  the minority  interest in subsidiary was transferred to
stockholders' equity on such date.

(d) Equity Financings

      On August 5, 2004,  the  Company  closed a private  placement  with select
institutional  investors  ("August 2004 Private  Placement")  for  approximately
3,617,300 shares of its Common Stock and warrants to purchase an aggregate of up
to approximately 1,085,200 shares of its Common Stock. Jefferies & Company, Inc.
acted as  Placement  Agent for which it received a fee and  warrants to purchase
Common Stock. The Company raised approximately $6,984,000 net proceeds from this
private offering.

      The Warrant issued to each  purchaser is exercisable  for up to 30% of the
number of shares of Common  Stock  purchased by such  Purchaser,  at an exercise
price  equal to $2.86 per share.  Each  Warrant  has a term of five years and is
fully exercisable from the date of issuance. Pursuant to the Registration Rights
Agreement,  made and entered into as of August 5, 2004 (the "Rights Agreement"),
the Company  registered  the resales of the shares issued to the  Purchasers and
shares issuable upon the exercise of the Warrants.

      By agreement with Cardinal Securities, LLC, for general financial advisory
services and in conjunction  with the August 2004 Private  Placement with select
institutional investors, the Company paid Cardinal Securities, LLC an investment
banking fee of $140,000.  The Company paid Cardinal  one-half of the fee in cash
with the remainder  being paid with the issuance of 50,000  warrants to purchase
common  stock  exercisable  at $2.50 per share  expiring  on March 31,  2010 and
46,667 shares of common stock. By agreement with Cardinal  Securities,  LLC, the
Company registered all of the foregoing shares and shares issuable upon exercise
of the above mentioned warrants for public resale.


                                      F-39


      On  July 8,  2005,  the  Company  entered  into a  common  stock  purchase
agreement with Fusion Capital Fund II, LLC ("Fusion Capital"), pursuant to which
Fusion Capital has agreed, under certain conditions, to purchase on each trading
day $40,000 of the  Company's  common stock up to an aggregate of $20.0  million
over  approximately  a 25 month period,  subject to earlier  termination  at the
Company's  discretion.  In the Company's  discretion,  it may elect to sell less
common  stock to Fusion  Capital  than the daily  amount and we may increase the
daily amount as the market price of the Company's stock increases.  The purchase
price of the  shares of common  stock  will be equal to a price  based  upon the
future market price of the common stock without any fixed discount to the market
price.  Fusion  Capital  does not have the right or the  obligation  to purchase
shares of the  Company's  common stock in the event that the price of the common
stock is less than $1.00.

      Pursuant to the Company's  agreement with Fusion Capital,  the Company has
registered  for public  sale by Fusion  Capital up to  10,795,597  shares of our
common stock.  However, in the event that the Company decides to issue more than
10,113,278,  i.e. greater than 19.99% of the outstanding  shares of common stock
as of the date of the  agreement,  the  Company  would  first  seek  stockholder
approval in order to be in compliance  with American Stock Exchange rules. As of
December 31, 2005,  Fusion Capital has purchased  4,007,255  shares amounting to
approximately $8,020,000 in gross proceeds to the Company.

      In connection  with entering into the above agreement with Fusion Capital,
the Company, in July 2005, issued to Fusion Capital 402,798 shares of its common
stock.  392,798 of these shares represented 50% of the commitment fee due Fusion
Capital with the remaining 10,000 shares issued as  reimbursement  for expenses.
An  additional  392,799  shares,  representing  the  remaining  balance  of  the
commitment,  are issuable in conjunction with daily purchases of common stock by
Fusion Capital.  These additional  commitment shares will be issued in an amount
equal to the product of (x) 392,799 and (y) the Purchase  Amount  Fraction.  The
"Purchase  Amount  Fraction"  means a fraction,  the  numerator  of which is the
purchase price at which the shares are being purchased by Fusion Capital and the
denominator of which is $20,000,000. As of December 31, 2005, Fusion Capital was
issued 263,713 shares towards this commitment fee. In total,  Fusion Capital has
purchased  4,673,766  shares in  connection  with this  private  placement as of
December 31, 2005 (See Note 20).

(e) Common Stock Options and Warrants

   (i) Stock Options

      The 1990 Stock  Option Plan  provides for the grant of options to purchase
up to 460,798 shares of the Company's Common Stock to employees,  directors, and
officers of the Company and to  consultants,  advisors,  and other persons whose
contributions  are  important to the success of the Company.  The  recipients of
options  granted  under the 1990 Stock Option  Plan,  the number of shares to be
converted  by each  option,  and the  exercise  price,  vesting  terms,  if any,
duration and other terms of each option  shall be  determined  by the  Company's
board of directors or, if delegated by the board, its Compensation Committee. No
option is exercisable more than 10 years and one month from the date as of which
an option  agreement is executed.  These shares  become vested  through  various
periods  not to exceed  four  years  from the date of grant.  The  option  price
represents the fair market value of each underlying share of Common Stock at the
date of grant, based upon the public trading price.

      In December  1992,  the Board of Directors  approved the 1992 Stock Option
Plan (the 1992 Stock  Option  Plan) which  provides  for the grant of options to
purchase  up to  92,160  shares  of the  Company's  Common  Stock to  employees,
directors,  and officers of the Company and to consultants,  advisors, and other
persons whose  contributions  are  important to the success of the Company.  The
recipients of the options  granted under the 1992 Stock Option Plan,  the number
of shares to be covered by each option,  and the exercise price,  vesting terms,
if any,  duration  and other terms of each  option  shall be  determined  by the
Company's  board of directors.  No option is exercisable  more than 10 years and
one month from the date as of which an option agreement is executed. To date, no
options have been granted under the 1992 Stock Option Plan.

      The Company's  1993 Employee  Stock Purchase Plan (the 1993 Purchase Plan)
was  approved by the board of  directors  in July 1993.  The outline of the 1993
Purchase  Plan  provides for the  issuance,  subject to  adjustment  for capital
changes, of an aggregate of 138,240 shares of Common Stock to employees.

      The 1993 Purchase Plan is  administered by the  Compensation  Committee of
the board of directors.  Under the 1993  Purchase  Plan,  Company  employees are
eligible  to  participate  in  semi-annual   plan  offerings  in  which  payroll
deductions  may be used to purchase  shares of Common Stock.  The purchase price
for such  shares is equal to the lower of 85% of the fair  market  value of such
shares on the date of grant or 85% of its fair  market  value of such  shares on
the date such right is  exercised.  There have been no offerings  under the 1993
Purchase Plan to date and no shares of Common Stock have been issued thereunder.

      During 2003, the Company  issued options to acquire  200,000 shares to its
general  counsel  under the 1990 plan for services  rendered.  As a result,  the
Company charged operating expenses in the amount of $237,000. There was no stock
compensation  expense in 2004 and 2005 recorded as there were no options granted
under this plan.

      The Equity  Incentive Plan effective May 1, 2004,  authorizes the grant of
non-qualified and incentive stock options, stock appreciation rights, restricted
stock and other stock awards.  A maximum of 8,000,000  shares of common stock is
reserved for potential  issuance  pursuant to awards under the Equity  Incentive
Plan.  Unless  sooner  terminated,  the Equity  Incentive  Plan will continue in
effect for a period of 10 years from its effective date.

      The Equity  Incentive Plan is administered by the Board of Directors.  The
Equity Incentive Plan provides for awards to be made to such officers, other key
employees,  non-employee directors,  consultants and advisors of the Company and
its subsidiaries as the Board may select.

      Stock options  awarded under the Equity  Incentive Plan may be exercisable
at such  times  (not  later  than 10 years  after the date of grant) and at such
exercise  prices (not less than fair  market  value at the date of grant) as the
Board may  determine.  The Board may provide  for options to become  immediately
exercisable upon a "change in control," which is defined in the Equity Incentive
Plan to occur  upon any of the  following  events:  (a) the  acquisition  by any
person or group, as beneficial  owner, of 20% or more of the outstanding  shares
or the voting power of the outstanding  securities of the Company;  (b) either a
majority of the directors of the Company at the annual stockholders  meeting has
been nominated  other than by or at the direction of the incumbent  directors of
the Board,  or the  incumbent  directors  cease to  constitute a majority of the
Company's  Board;  (c) the  Company's  stockholders  approve  a merger  or other
business  combination  pursuant  to which the  outstanding  common  stock of the
Company no longer  represents  more than 50% of the  combined  entity  after the
transaction;   (d)  the  Company's  shareholders  approve  a  plan  of  complete
liquidation or an agreement for the sale or disposition of all or  substantially
all of the Company's assets;  or (e) any other event or circumstance  determined
by the  Company's  Board to affect  control of the  Company  and  designated  by
resolution of the Board as a change of control.

      Certain of the stock warrants  outstanding  are subject to adjustments for
stock splits and dividends.

Warrants issued to stockholders

      At December 31, 2001 there were 232,160  warrants  issued to  stockholders
remaining.  In 2002, 10,000 were converted to common stock. At December 31, 2002
and 2003 there were 222,160 warrants  remaining.  These warrants had an exercise
price of $3.50 per share.

      In November  1994,  the Company  granted  Rule 701 Warrants to purchase an
aggregate of 2,080,000 shares of Common Stock to certain officers and directors.
These Warrants are exercisable at $3.50 per share and, if not exercised, were to
expire in September,  1999. On February 19, 1999 the Board of Directors extended
the  expiration  date for  three  more  years.  In 1999  235,000  warrants  were

to now expire on September 30, 2007. These stock warrants have an exercise price
of $3.50. In accordance with FASB  Interpretation No. 44, Accounting for Certain
Transactions   involving  Stock  Compensation,   no  compensation   expense  was
recognized as the exercise  price at the extension  date exceeded the fair value
of the underlying common stock.


                                      F-44


      In May 1995, the Company and certain officers,  directors and shareholders
entered into a standby finance agreement pursuant to which the parties agreed to
provide an aggregate of  $5,500,000  in financing to the Company  during 1995 in
the event that existing and additional  financing was  insufficient to cover the
cash needs of the Company  through  December 31, 1996. In exchange,  the Company
issued warrants to purchase an aggregate of 2,750,000  shares of Common Stock at
$1.75 per share to the parties.  In 1996,  597,000,  in 1999,  290,000, in 2000,
216,500,  in 2001, 200,000, in 2002, 1,300, in 2003, 35,000 and in 2004, 205,000
of these  warrants  were  exercised  leaving  a  balance  of these  warrants  of
1,205,200.  5,000 of these  remaining  warrants  were  exercised in 2005 and the
remaining expired on June 30, 2005.

      In the years 2001, 2002 and 2003, the Company issued  450,000,  25,000 and
no warrants,  respectively,  exclusive of warrants issued in connection with the
Company's 2003 Debenture issuances (see Note 8), to investment banking firms for
services performed on behalf of the Company.  Accordingly,  the Company recorded
stock  compensation of $637,000,  $133,000 and none for the years 2001, 2002 and
2003,  respectively.  These warrants have various  vesting dates and exercisable
prices ranging from $4.00 to $16.00 per share. In total, 1,193,800 warrants were
outstanding  at December 31, 2002. In 2003,  225,000 of these  warrants  expired
leaving a balance of 968,800 warrants at December 31, 2003. In 2004,  193,800 of
these  warrants  expired  leaving a balance of 775,000  warrants at December 31,
2004. In 2005,  350,000 of these warrants  expired leaving a balance of 425,000.
These warrants are exercisable in five years from the date of issuance.

      In 2003,  2004 and 2005 the Company had  warrants  outstanding,  issued to
employees,  directors and  consultants,  of  5,100,650,  4,645,650 and 4,268,650
respectively.  These warrants were not issued pursuant to an equity plan and are
exercisable at rates of $1.55 to $10.00 per share of common stock.  The exercise
price was equal to the fair market  value of the stock on the date of grant.  At
December 31, 2002, 3,701,650 of the non-public warrants were outstanding. During
2003 the Company granted 1,450,000  warrants to employees with an exercise price
of $2.20 for services  performed and 51,000  warrants  expired.  At December 31,
2003,  5,100,650  warrants were  outstanding.  During 2004, 15,000 warrants were

(f) Stock Repurchase

      The  Company's  repurchases  of  shares of common  stock are  recorded  as
"Treasury  Stock" and result in a  reduction  of  "Stockholders'  equity."  When
treasury shares are reissued, the Company uses a first-in,  first-out method and
the excess of repurchase cost over reissuance price is treated as a reduction of
"Additional  paid-in capital." At December 31, 2003 there were 443 shares in the
treasury.  During  2003 most of the then  existing  treasury  shares were either
re-issued or retired. There was no Treasury Stock repurchased, re-issued and the
balance of 443 shares were sold in 2004.

(g) Rights offering

      On November 19, 2002, the Board of Directors of Hemispherx Biopharma, Inc.
(the  "Company")  declared  a  dividend  distribution  of  one  Right  for  each
outstanding  share of  Common  Stock to  stockholders  of record at the close of
business on November  29, 2002 (the  "Record  Date").  Each Right  entitles  the
registered  holder  to  purchase  from  the  Company  a unit  consisting  of one
one-hundredth of a share (a "Unit") of Series A Junior  Participating  Preferred
Stock,  par value $.01 per share (the "Series A Preferred  Stock") at a Purchase
Price of $30.00 per Unit,  subject to adjustment.  The  description and terms of
the Rights are set forth in a Rights Agreement (the "Rights  Agreement") between
the Company and Continental Stock Transfer & Trust Company, as Rights Agent.

      Initially,  the  Rights are  attached  to all  Common  Stock  certificates
representing  shares then outstanding,  and no separate Rights Certificates will
be distributed. Subject to certain exceptions specified in the Rights Agreement,
the Rights will  separate  from the Common  Stock and a  Distribution  Date will
occur upon the  earlier of (i) 10 days  following a public  announcement  that a
person or group of affiliated or associated persons (an "Acquiring  Person") has
acquired  beneficial  ownership  of 15% or more (or 20% or more for  William  A.
Carter,  M.D.) of the outstanding shares of Common Stock (the "Stock Acquisition
Date"), other than as a result of repurchases of stock by the Company or certain
inadvertent  actions by institutional  or certain other  stockholders or (ii) 10
business  days (or such later date as the Board shall  determine)  following the
commencement  of a tender offer or exchange  offer that would result in a person
or group  becoming an Acquiring  Person.  Until the  Distribution  Date, (i) the
Rights  will  be  evidenced  by  the  Common  Stock  certificates  and  will  be
transferred with and only with such Common Stock  certificates,  (ii) new Common
Stock  certificates  issued  after  the  Record  Date will  contain  a  notation
incorporating  the Rights  Agreement by reference  and (iii) the  surrender  for
transfer of any certificates  for Common Stock  outstanding will also constitute
the transfer of the Rights  associated with the Common Stock represented by such
certificate. Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the  occurrence of a Triggering  Event (as defined below) that,
upon any exercise of Rights,  a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

(10) Segment and Related Information

      The  Company  operates  in  one  segment,   which  performs  research  and
development activities related to Ampligen(R) and other drugs under development,

foreign operations.

(11) Research, Consulting and Supply Agreements

      In 1994,  the Company  entered into a licensing  agreement  with Bioclones
(Proprietary)  limited  ("Bioclones") for manufacturing and international market
development in Africa,  Australia,  New Zealand,  Tasmania,  the United Kingdom,
Ireland and certain countries in South Africa, of Ampligen(R) and Oragen(TM). On
December 27, 2004 the Company initiated a lawsuit in Federal Court identifying a
conspiratorial  group seeking to illegally  manipulate  the Company's  stock for
purposes of bringing about a hostile takeover of Hemispherx. This conspiratorial
group includes Bioclones.

      In 1998,  the Company  entered into a strategic  alliance  with Accredo to
develop  certain  marketing and  distribution  capacities for Ampligen(R) in the
United States. Accredo is one of the nation's largest home health care companies
with over 400 offices and sixty thousand caregivers nationwide.  Pursuant to the
agreement,   Accredo  assumed  certain   responsibilities  for  distribution  of
Ampligen(R) for which they received a fee. Through this arrangement, the Company
may mitigate the necessity of incurring certain up-front costs. Accredo has also
worked with the  Company in  connection  with the Amp 511 ME/CFS  cost  recovery
treatment  program,  Amp 516  ME/CFS  Phase III  clinical  trial and the Amp 719
(combining Ampligen(R) with other antiviral drugs in HIV-salvage therapy and Amp
720 HIV Phase IIb  clinical  trials now under way).  There can be no  assurances
that this alliance will develop a significant  commercial position in any of its
targeted  chronic  disease  markets.  The agreement had an initial one year term
from February 9, 1998 with  successive  additional  one year terms unless either
party notifies the other not less than 180 days prior to the anniversary date of
its intent to terminate the agreement. Also, the agreement may be terminated for
uncured  defaults,  or  bankruptcy,  or  insolvency  of  either  party  and will
automatically terminate upon the Company's receiving an NDA for Ampligen(R) from
the FDA, at which time, a new agreement will need to be negotiated  with Accredo
or another major drug distributor. There were no initial fees.

      In December,  1999,  the Company  entered  into an agreement  with Biovail
Corporation International ("Biovail").  Biovail is an international full service
pharmaceutical   company   engaged  in  the   formulation,   clinical   testing,
registration and manufacture of drug products  utilizing  advanced drug delivery
systems.  Biovail is  headquartered  in Toronto,  Canada.  The agreement  grants
Biovail the exclusive  distributorship  of the Company's product in the Canadian
territories subject to certain terms and conditions.  In return,  Biovail agrees
to  conduct  certain  pre-marketing  clinical  studies  and  market  development
programs, including without limitation,  expansion of the Emergency Drug Release
Program in Canada with respect to the Company' products.  Biovail agrees to work
with the Company in preparing and filing of a New Drug  Submission with Canadian
Regulatory  Authorities.  Biovail invested $2.25 million in Hemispherx equity at
prices above the then current  market price and agreed to make further  payments
based on reaching certain regulatory milestones.  The Agreement requires Biovail
to  penetrate  certain  market  segments at specific  rates in order to maintain
market  exclusivity.  The agreement  terminates on December 15, 2009, subject to
successive two-year extensions by the parties and subject to earlier termination
by  the  parties  for  uncured  defaults  under  the  agreement,  bankruptcy  or
insolvency of either party,  or withdrawal of the Company's  product from Canada
for a period of more  than  ninety  days for  serious  adverse  health or safety
reasons.


                                      F-47


      In May 2000, the Company acquired an interest in Chronix  Biomedical Corp.
("CHRONIX").  Chronix  focuses upon the  development of diagnostics  for chronic
diseases.  The Company issued 100,000 shares of common stock to Chronix toward a
total equity investment of $700,000. Pursuant to a strategic alliance agreement,
the Company  provided  Chronix with $250,000 to conduct research in an effort to
develop  intellectual  property on potential  new products  for  diagnosing  and
treating  various  chronic  illnesses  such as ME/CFS.  The  strategic  alliance
agreement  provides the Company  certain  royalty rights with respect to certain
diagnostic  technology developed from this research and a right of first refusal
to license  certain  therapeutic  technology  developed from this research.  The
strategic  alliance agreement provides the Company with a royalty payment of 10%
of all net sales of diagnostic  technology  developed by Chronix for  diagnosing
Chronic Fatigue Syndrome,  Gulf War Syndrome and Human Herpes Virus-6 associated
diseases.  The royalty  continues for the longer of 12 years from  September 15,
2000  or  the  life  of any  patent(s)  issued  with  regard  to the  diagnostic
technology.  The strategic alliance agreement also provides the Company with the
right of first refusal to acquire an exclusive worldwide license for any and all
therapeutic  technology developed by Chronix on or before September 14, 2012 for
treating  Chronic Fatigue  Syndrome,  Gulf War Syndrome and Human Herpes Virus-6
associated  diseases.  During the quarter ended  December 31, 2002 and September
30,  2004 the  Company  recorded  a noncash  charge of  $292,000  and  $373,000,
respectively,  with  respect  to  the  Company's  investment  in  Chronix.  This
impairment  reduces the Company's  carrying value to reflect a permanent decline
in Chronix's market value based on its then proposed equity offerings.

      In March 2002, the Company's European  subsidiary  Hemispherx S.A. entered
into a Sales and  Distribution  agreement with Esteve.  Pursuant to the terms of
the Agreement,  Esteve was granted the exclusive right to market  Ampligen(R) in
Spain,  Portugal and Andorra for the  treatment of ME/CFS.  In addition to other
terms and other projected  payments,  Esteve agreed to conduct certain  clinical
trials using Ampligen(R) in the patient  population  coinfected with HCV and HIV
viruses.  The Agreement  runs for the longer of ten years from the date of first
arms-length sale in the Territory,  the expiration of the last Hemispherx patent
exploited by Esteve or the period of regulatory  data protection for Ampligen(R)
in the applicable territory. Pursuant to the terms of the agreement Esteve is to
conduct  clinical  trials using  Ampligen(R) to treat patients with both HCV and
HIV and is required to purchase  certain  minimum  annual amounts of Ampligen(R)
following regulatory  approval.  Esteve initiated the HIV/HCV clinical trials in
Spain in late 2004,  but did not proceed  with the trials due to an inability to
enroll a sufficient  number of patients.  The Company is discussing  with Esteve
their  initiation of another  clinical  trial  utilizing  Ampligen(R) in another
indication.  The  agreement  is  terminable  by either party if  Ampligen(R)  is
withdrawn  from the  territory  for a  specified  period due to serious  adverse
health or safety reasons; bankruptcy, insolvency or related issues of one of the
parties;  or material  breach of the  agreement.  Hemispherx  may  transform the
agreement into a non-exclusive agreement or terminate the agreement in the event
that Esteve does not meet specified  percentages of its annual minimum  purchase
requirements  under the  agreement.  Esteve may  terminate  the agreement in the
event  that  Hemispherx  fails to  supply  Ampligen(R)  to the  territory  for a
specified  period  of  time  or  certain  clinical  trials  being  conducted  by
Hemispherx  are not  successful.  The last patent with respect to this agreement
expires on June 5, 2012.


                                      F-48


      In October 2005, the Company signed a research agreement with the National
Institute of Infectious Diseases, in Tokyo, Japan. The collaboration,  by Hideki
Hasegawa,  M.D., Ph.D., Chief of the Laboratory of Infectious Disease Pathology,
will  assess  the   Company's   experimental   therapeutic   Ampligen(R)   as  a
co-administered immunotherapeutic to the Institution's nasal flu vaccine.

      In October 2005,  the Company also engaged the Sage Group,  Inc., a health
care, technology oriented, strategy and transaction advisory firm, to assist the
Company in obtaining a strategic alliance in Japan for the use of Ampligen(R) in
treating  Chronic  Fatigue  Syndrome  or CFS (see Note 17).  The  Company  is in
discussions  with the Sage Group,  Inc. to expand its  engagement  to assist the
Company in obtaining  strategic  alliance in Japan for the use of Ampligen(R) in
treating Avian Flu.

      In November 2005,  the Company  entered into an agreement with Defence R&D
Canada,  Suffield  ("DRDC  Suffield"),  an agency of the Canadian  Department of
National  Defence,   to  evaluate  the  antiviral   efficacy  of  the  Company's
experimental therapeutic Ampligen(R) and Alferon(R) for protection against human
respiratory  influenza  virus  infection in well validated  animal models.  DRDC
Suffield  is  conducting  research  and  development  of new  drugs  that  could
potentially  become part of the arsenal of existing  antiviral weapons to combat
the bird flu.  The initial  study will focus on the testing of  potential  drugs
against the respiratory  influenza virus infection on a mouse-adapted  strain of
human influenza.

      On  December  9,  2005,  the  Company  executed  a Supply  Agreement  with
Hollister-Stier Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for
the contract  manufacturing of Ampligen(R) for a five year term. Pursuant to the
agreement the Company will supply the key raw materials and Hollister-Stier will
formulate  and bottle the  Ampligen(R).  In  November  2005,  the  Company  paid
$100,000  as a deposit in order to  initiate  the  manufacturing  project.  This
deposit was expensed as research and  development  during the 4th Quarter  2005.
The  achievement  of the  initial  objectives  described  in the  agreement,  in
combination with the Company's polymer production facility under construction in
New Brunswick, N.J., may enable the Company to manufacture the raw materials for
approximately  10,000  doses of  Ampligen(R)  per week.  The Company  executed a
confidentiality agreement with Hollister-Stier; therefore, the Company commenced
the  transfer of the  Company's  manufacturing  technology  to  Hollister-Stier.
Currently,  Hollister-Stier  has  completed  two  pilot  manufacturing  runs  of
Ampligen(R) for stability testing.


                                      F-49


      The Company has entered into agreements for consulting services, which are
performed at medical research  institutions and by medical and clinical research
individuals. The Company's obligation to fund these agreements can be terminated
after the initial funding period, which generally ranges from one to three years
or on an as-needed monthly basis. During the year ending December 31, 2003, 2004
and 2005 the Company  incurred  approximately  $389,000,  $220,000  and $236,000
respectively, of consulting service fees under these agreements. These costs are
charged to research and development expense as incurred.

(12) 401(K) Plan

      The Company  has a defined  contribution  plan,  entitled  the  Hemispherx
Biopharma Employees 401(K) Plan and Trust Agreement (the 401(K) Plan). Full time
employees  of the  Company  are  eligible  to  participate  in the  401(K)  Plan
following  one year of  employment.  Subject to certain  limitations  imposed by
federal tax laws,  participants  are eligible to  contribute  up to 15% of their
salary  (including   bonuses  and/or   commissions)  per  annum.   Participants'
contributions  to the  401(K)  Plan  may be  matched  by the  Company  at a rate
determined annually by the Board of Directors.

      Each  participant   immediately  vests  in  his  or  her  deferred  salary
contributions,  while  Company  contributions  will vest over one year. In 2003,
2004 and 2005 the Company provided  matching  contributions to each employee for
up to 6% of annual pay aggregating $38,000, $77,000 and $89,000 respectively.

(13) Royalties, License, and Employment Agreements

      The Company  also has entered into a licensing  agreement  with a group of
individuals  and Hahnemann  University  relating to their  contributions  to the
development of certain compounds, including Ampligen(R), and to obtain exclusive
information  and  regulatory  rights  relating  to these  compounds.  Under this
agreement,  the Company will pay 2% of net sales proceeds of Ampligen(R)  not to
exceed an aggregate amount of $6 million per year through 2005.

      The Company acquired a series of patents on Oragens,  potentially a set of
oral broad spectrum antivirals and immunological enhancers,  through a licensing
agreement with Temple University in Philadelphia, PA. The Company was granted an
exclusive  worldwide  license  from  Temple  for  the  Oragens  products.  These
compounds have been evaluated in various  academic  laboratories for application
to  chronic  viral  and  immunological  disorders.  The  2',  5'  oligoadenylate
synthetase/RNase L system is an important and widely distributed pathway for the
inhibition  of viral  replication  and tumor growth.  The 2', 5'  oligoadenylate
synthetase,   up  activation  by   double-stranded   RNA,   synthesizes  2',  5'
oligoadenylates  (2-5A) from ATP. These bioactive 2-5As directly  activate RNase
L, which degrades viral and cellular RNAs resulting in the inhibition of protein
synthesis.  The bioactive 2-5A  molecules can be degraded by various  hydrolytic
enzymes,  resulting in a short half life.  Analogues of these  bioactive  2-5As,
termed  Oragen(TM) RNA compounds,  have been produced to increase  stability and
maintain or increase biological activity without demonstrable toxicity. Pursuant
to the terms of the Company's agreement with Temple, the Company is obligated to
pay  royalties  of 2% to 4% of  sales  depending  on  the  amount  of  technical
assistance required. The Company currently pays a royalty of $30,000 per year to
Temple.  This  agreement  is to remain  in  effect  until the date that the last
licensed  patent expires unless  terminated  sooner by mutual consent or default
due to royalties not being paid. The last  Oragen(TM)  patent expires on June 1,
2018. The Company records the payment of the royalty as research and development
cost for the period incurred.

      In October  1994,  the Company  entered  into a licensing  agreement  with
Bioclones (Propriety) Limited  (SAB/Bioclones) with respect to co-development of
various RNA drugs, including  Ampligen(R),  for a period ending three years from
the expiration of the last licensed patents.  The licensing  agreement  provided
SAB/Bioclones with an exclusive  manufacturing and marketing license for certain
southern  hemisphere  countries  (including  certain countries in South America,
Africa and  Australia as well as the United  Kingdom and Ireland  (the  licensed
territory).  We deem this marketing  arrangement  with Bioclones void due to the
numerous and long standing failures of performance by Bioclones.

      In December  2004,  the Company  filed a  multicount  complaint in federal
court  (Southern  District of Florida)  against a  conspiratorial  group,  which
includes  Bioclones,  seeking to illegally  manipulate  the Company's  stock for
purposes of bringing about a hostile takeover of Hemispherx (see Note 16).

      In October 1994, the Board of Directors granted an at the time director of
the Company  the right to receive 3% of gross  proceeds  of any  licensing  fees
received by the Company pursuant to the SAB/Bioclones licensing agreement, a fee
of .75% of gross  proceeds in the event that SAB Bioclones  makes a tender offer
for all or  substantially  all of the  Company's  assets,  including  a  merger,
acquisition or related transaction, and a fee of 1% on all products manufactured
by SAB Bioclones.

      On March 20, 2002, the Company's European subsidiary  Hemispherx Biopharma
Europe, S.A. ("Hemispherx S.A.") entered into a sales and Distribution agreement
with Laboratories Del Dr. Esteve S.A.  ("Esteve").  Pursuant to the terms of the
agreement,  Esteve was  granted the  exclusive  right to market  Ampligen(R)  in
Spain,  Portugal  and  Andorra  for the  treatment  of  Myalgic/Chronic  Fatigue
Syndrome  ("ME/CFS").  In addition to other terms and other projected  payments,
Esteve paid an initial and  non-refundable  fee of 625,000 Euros  (approximately
$563,000)  to  Hemispherx  S.A.  on April  24,  2002.  Esteve is to pay a fee of
1,000,000 Euros after U.S. Food and Drug Administration  approval of Ampligen(R)
for the treatment of ME/CFS and a fee of 1,000,000  Euros upon Spain's  approval
of the final marketing  authorization for using Ampligen(R) for the treatment of
ME/CFS.

      In connection with the asset purchase agreement entered into with ISI, the
Company is  obligated  to pay ISI a 6% royalty on the net sales of the Alferon N
Injection(R) product.

      The Company  has  contractual  agreements  with two of its  officers.  The
aggregate annual base compensation under these contractual  agreements for 2003,
2004 and 2005 was  $637,000,  $761,000 and $701,000  respectively.  In addition,
certain of these officers are entitled to receive  performance  bonuses of up to
25% of the annual base salary (in addition to the bonuses  described  below). In
2003, 2004 and 2005, bonuses of $266,100, 165,300 and $175,300 respectively were
granted.  In 2003, the Chief Executive  Officer,  Dr. William A. Carter,  of the
Company was granted  warrants to purchase  1,450,000  shares of common  stock at
$2.20 per share. The Chief Executive Officer's  employment agreement (see below)
provides for bonuses  based on gross  proceeds  received by the Company from any
joint venture or corporate  partnering  agreement.  In 2004, the Chief Executive
Officer of the Company was granted options to purchase  320,000 shares of common
stock at $2.60 per share and $3.44 per share and the Chief Financial  Officer of
the Company was granted  options to purchase  63,824  shares of common  stock at
$2.60 and $3.44 per share. In 2005, the Chief  Executive  Officer of the Company
was granted options to purchase 645,000 shares of common stock at $1.75 to $2.87
per share and the Chief Financial  Officer of the Company was granted options to
purchase 110,000 shares of common stock at $1.75 to $2.61 per share.


                                      F-51


      On March 11, 2005, the Company's board of directors, at the recommendation
of the  Compensation  Committee,  approved  an amended and  restated  employment
agreement and an amended and restated  engagement  agreement with Dr. William A.
Carter.

      The amended and restated  employment  agreement  provides for Dr. Carter's
employment as the Company's Chief Executive Officer and Chief Scientific Officer
until December 31, 2010 unless sooner  terminated  for cause or disability.  The
agreement automatically renews for successive one year periods after the initial
termination  date unless the Company or Dr. Carter give written notice otherwise
at least ninety days prior to the termination  date or any renewal  period.  Dr.
Carter  has the right to  terminate  the  agreement  on 30 days'  prior  written
notice.  The initial  base salary  retroactive  to January 1, 2005 is  $290,888,
subject to adjustment  based on the average increase or decrease in the Consumer
Price Index for the prior year. In addition,  Dr. Carter could receive an annual
performance bonus of up to 25% of his base salary, at the sole discretion of the
Compensation  Committee of the board of directors,  based on his  performance or
the  Company's  operating  results.  Dr.  Carter  will  not  participate  in any
discussions concerning the determination of his annual bonus. Dr. Carter is also
entitled to an incentive bonus of 0.5% of the gross proceeds received by us from
any joint venture or corporate  partnering  arrangement.  Dr. Carter's agreement
also provides that he be paid a base salary and benefits through the last day of
the then term of the agreement if he is terminated without "cause", as that term
is defined in agreement. In addition,  should Dr. Carter terminate the agreement
or the agreement be  terminated  due to his death or  disability,  the agreement
provides that Dr Carter be paid a base salary and benefits  through the last day
of the month in which the  termination  occurred  and for an  additional  twelve
month period. Pursuant to his original agreement, Dr. Carter was granted options
to purchase  73,728 (post split)  shares in 1991.  The exercise  period of these
options  is  extended  through  December  31,  2010  and,  should  Dr.  Carter's
employment agreement be extended beyond that date, the option exercise period is
further  extended  to the  last  day  of  the  extended  employment  period.  In
accordance with FASB Interpretation No. 44, Accounting for Certain  Transactions
involving  Stock  Compensation,  no  compensation  expense was recognized as the
exercise  price at the extension  date exceeded the fair value of the underlying
common stock.

      The amended and restated engagement  agreement,  retroactive to January 1,
2005,  provides  for the  Company's  engagement  of Dr.  Carter as a  consultant
related to patent development, as one of the Company's directors and as chairman
of the Executive  Committee of the Company's  board of directors  until December
31,  2010  unless  sooner  terminated  for cause or  disability.  The  agreement
automatically   renews  for  successive  one  year  periods  after  the  initial
termination  date or any renewal  period.  Dr. Carter has the right to terminate
the  agreement  on 30 days' prior  written  notice.  The initial  base fee as of
January  1,  2004 is  $207,777,  subject  to  annual  adjustments  equal  to the
percentage  increase or  decrease  of annual  dollar  value of  directors'  fees
provided to the  Company's  directors  during the prior year.  The annual fee is
further subject to adjustment  based on the average  increase or decrease in the
Consumer  Price Index for the prior year. In addition,  Dr. Carter could receive
an annual  performance bonus of up to 25% of his base fee, at the sole direction
of  the  Compensation  Committee  of  the  board  of  directors,  based  on  his
performance.  Dr. Carter will not participate in any discussions  concerning the
determination of this annual bonus. Dr. Carter's agreement also provides that he
be paid his base fee through the last day of the then term of the  agreement  if
he is terminated without "cause",  as that term is defined in the agreement.  In
addition,  should  Dr.  Carter  terminate  the  agreement  or the  agreement  be
terminated  due to his death or  disability,  the  agreement  provides  that Dr.
Carter  be paid  fees due him  through  the last day of the  month in which  the
termination occurred and for an additional twelve month period.


                                      F-52


      On February 14, 2005 the Company  entered into an agreement  with The Sage
Group of Branchburg,  New Jersey for R. Douglas Hulse, an Executive  Director of
The Sage  Group,  to serve as  President  and  Chief  Operating  Officer  of the
Company.  In addition,  other Sage Group principals and Senior Directors will be
made available to assist as needed. The engagement is expected to continue for a
period of 18 months;  however,  it is  terminable  on 30 days written  notice by
either party after 12 months.  Compensation for the services includes a ten year
warrant to purchase  250,000 shares of the Company's common stock at an exercise
price of $1.55. These warrants are to be issued to Sage Healthcare Advisors, LLC
and are to vest at the rate of 12,500 per month of the  engagement  with  25,000
vesting upon  completion of the  eighteenth  month.  Vesting  accelerates in the
event of a merger or a purchase of a majority of the Company's assets or equity.
The Sage Group also is to receive a monthly  retainer  of $10,000 for the period
of the engagement.  In addition, for each calendar year (or part thereof) during
which  the  agreement  is in  effect,  The Sage  Group  will be  entitled  to an
incentive bonus in an amount equal to 0.5% of the gross proceeds  received by us
during such year from any joint ventures or corporate  partnering  arrangements.
After  termination  of the  agreement,  The Sage Group will only be  entitled to
receive the incentive bonus based upon gross proceeds  received by us during the
two year period  commencing on the  termination of the agreement with respect to
any joint  ventures or  corporate  partnering  arrangements  entered  into by us
during the term of the agreement. Mr. Hulse will devote approximately two to two
and one half  days per week to the  Company's  business.  The  Company  used the
Black-Scholes  valuation  model to value the shares  received  by the Sage Group
pursuant  to the  agreement.  The  Company  recorded  a charge  to  earnings  of
approximately  $124,000 in 2005 with a related  increase to  additional  paid in
capital.

      The Company entered into an engagement  agreement,  retroactive to January
1, 2005, with Ransom W. Etheridge which provides for Mr. Etheridge's  engagement
as  the  Company's  General  Counsel  until  December  31,  2009  unless  sooner
terminated  for cause or  disability.  The  agreement  automatically  renews for
successive  one year  periods  after the  initial  termination  date  unless the
Company or Mr.  Etheridge  give  written  notice  otherwise at least ninety days
prior to the termination date or any renewal period. Mr. Etheridge has the right
to terminate the agreement on 30 days' prior written notice.  The initial annual
fee for services is $96,000 and is annually  subject to adjustment  based on the
average increase or decrease in the Consumer Price Index for the prior year. Mr.
Etheridge's  agreement  also  provides that he be paid all fees through the last
day of then current term of the agreement if he is terminated without "cause" as
that term is  defined  in the  agreement.  In  addition,  should  Mr.  Etheridge
terminate  the  agreement  or the  agreement be  terminated  due to his death or
disability,  the agreement  provides that Mr. Etheridge be paid the fees due him
through the last day of the month in which the  termination  occurred and for an
additional twelve month period.  Mr. Etheridge will devote  approximately 85% of
his business time to the Company's business.

      The Company  entered  into an amended and restated  engagement  agreement,
retroactive  to January 1, 2005,  with Robert E. Peterson which provides for Mr.
Peterson's  engagement as the Company's Chief  Financial  Officer until December
31, 2010 unless sooner terminated for cause or disability.  Mr. Peterson has the
right to terminate the agreement on 30 days' prior written  notice.  The initial
annual fee for services is $202,680 and is annually  subject to increases  based
on the average  increase in the cost of inflation  index for the prior year. Mr.
Peterson  shall  receive an annual bonus in each year that the  Company's  Chief
Executive  Officer is granted a bonus. The bonus shall equal a percentage of Mr.
Peterson's base annual compensation  comparable to the percentage bonus received
by the Chief Executive  Officer.  In addition,  Mr. Peterson shall receive bonus
compensation upon Federal Drug Administration approval of commercial application
of Ampligen(R).  Mr. Peterson's agreement also provides that he be paid all fees
through the last day of then current term of the  agreement if he is  terminated
without  "cause" as that term is defined in the agreement.  In addition,  should
Mr.  Peterson  terminate the agreement or the agreement be terminated due to his
death or disability,  the agreement  provides that Mr. Peterson be paid the fees
due him through the last day of the month in which the termination  occurred and
for an additional  twelve month period.  Mr. Peterson will devote  approximately
85% of his business time to the Company's business.


                                      F-53


      On March 11, 2005 the Board of Directors, deeming it essential to the best
interests of the Company's  shareholders to foster the continuous  engagement of
key management personnel and recognizing that, as is the case with many publicly
held  corporations,  a change of control might occur and that such  possibility,
and the uncertainty and questions which it might raise among  management,  might
result in the departure or distraction of management  personnel to the detriment
of the Company and the  Company's  shareholders,  determined  to  reinforce  and
encourage  the continued  attention  and  dedication of members of the Company's
management to their  engagement  without  distraction in the face of potentially
disturbing  circumstances arising from the possibility of a change in control of
the Company and entered into identical  agreements  regarding  change in control
with  William  A.  Carter,  the  Company's  Chief  Executive  Officer  and Chief
Scientific  Officer,  Robert E. Peterson,  the Company's Chief Financial Officer
and Ransom W. Etheridge,  the Company's General Counsel.  Each of the agreements
regarding change in control became effective March 11, 2005 and continue through
December  31,  2007 and shall  extend  automatically  to the  third  anniversary
thereof  unless the Company  gave notice to the other party prior to the date of
such extension that the agreement term will not be extended. Notwithstanding the
foregoing, if a change in control occurs during the term of the agreements,  the
term of the agreements will continue through the second  anniversary of the date
on which the change in control occurred. Each of the agreements entitles William
A. Carter, Robert E. Peterson and Ransom W. Etheridge,  respectively,  to change
of control  benefits,  as defined in the agreements and summarized  below,  upon
their respective termination of employment/engagement  with the Company during a
potential  change in control,  as defined in the agreements or after a change in
control,  as defined in the agreements,  when their respective  terminations are
caused (1) by us for any reason other than  permanent  disability  or cause,  as
defined in the  agreement (2) by William A. Carter,  Robert E.  Peterson  and/or
Ransom W. Etheridge,  respectively,  for good reason as defined in the agreement
or, (3) by William A. Carter,  Robert E. Peterson  and/or  Ransom W.  Etheridge,
respectively  for any reason  during the 30 day period  commencing  on the first
date which is six months after the date of the change in control.

The benefits for each of the foregoing executives would be as follows:

      o     A lump sum cash  payment of three  times his base  salary and annual
            bonus amounts; and

      o     Outplacement benefits.


                                      F-54


Each  agreement  also  provides  that the  executive is entitled to a "gross-up"
payment  to make him whole  for any  federal  excise  tax  imposed  on change of
control or severance  payments  received by him.  Dr.  Carter's  agreement  also
provides for the following benefits:

      o     Continued  insurance  coverage through the third  anniversary of his
            termination; and

      o     Retirement  benefits computed as if he had continued to work for the
            above period.

      In order to facilitate the Company's need to obtain financing and prior to
the Company's  shareholders  approving an amendment to the  Company's  corporate
charter to merge the number of  authorized  shares,  Dr.  Carter,  the Company's
Chief Executive Officer,  agreed to waive his right to exercise certain warrants
and options unless and until the Company's  shareholder  approved an increase in
the Company's authorized shares of Common Stock.

      In October 2003,  in  recognition  of this action as well as Dr.  Carter's
prior and on-going efforts relating to product  development  securing critically
needed  financing and the  acquisition of a new product line,  the  Compensation
Committee  determined  that Dr.  Carter be awarded  bonus  compensation  in 2003
consisting  of $196,636 and a grant of 1,450,000  stock  warrants for a value of
$1,769,000 with an exercise price of $2.20 per share. These warrants vested upon
the  second ISI Asset  closing  during the first  quarter  2004 and the  Company
recorded stock compensation of $1,769,000.

      The Company has engaged the Sage Group,  Inc., a health  care,  technology
oriented,  strategy  and  transaction  advisory  firm,  to assist the Company in
obtaining a strategic  alliance in Japan for the use of  Ampligen(R) in treating
Chronic Fatigue Syndrome or CFS. R. Douglas Hulse,  the Company's  President and
Chief  Operating  Officer,  is a member and an  executive  director  of The Sage
Group, Inc.

      Rent expense  charged to operations for the years ended December 31, 2003,
2004  and  2005  amounted  to  approximately  $266,000,  $269,000  and  $284,000
respectively. The term of the lease for the Rockville, Maryland facility expired
June 2005. The Company  transferred  this  operational site to the Company's New
Jersey  facility.  The  term of the  lease  for the  Philadelphia,  Pennsylvania
offices is through April,  2007 with an average rent of $15,000 per month,  plus
applicable taxes and charges.


                                      F-55


(15) Income Taxes

      As of December  31, 2005,  the Company has  approximately  $81,500,000  of
federal net  operating  loss  carryforwards  (expiring in the years 2006 through
2026) available to offset future federal  taxable  income.  The Company also has
approximately $28,000,000 of state net operating loss carryforwards (expiring in
the years 2006 through 2010)  available to offset  future state taxable  income.
The utilization of certain state net operating loss carryforwards may be subject
to annual limitations.

      Under the Tax Reform Act of 1986, the utilization of a  corporation's  net
operating loss  carryforward  is limited  following a greater than 50% change in
ownership.  Due to the  Company's  prior and current  equity  transactions,  the
Company's  net  operating  loss  carryforwards  may  be  subject  to  an  annual
limitation  generally  determined by multiplying the value of the Company on the
date of the  ownership  change by the federal  long-term  tax exempt  rate.  Any
unused annual  limitation may be carried forward to future years for the balance
of the net operating loss carryforward period.

      Deferred income taxes reflect the net tax effects of temporary differences
between  carrying  amounts of assets and  liabilities  for  financial  reporting
purposes and the carrying amounts used for income tax purposes. In assessing the
realizability of deferred tax assets,  management  considers  whether it is more
likely than not that some  portion or all of the deferred tax assets will not be
realized.  The  realization  of  deferred  tax  assets  is  dependent  upon  the
generation  of future  taxable  income  during the  periods  in which  temporary
differences representing net future deductible amounts become deductible. Due to
the uncertainty of the Company's  ability to realize the benefit of the deferred
tax asset, the deferred tax assets are fully offset by a valuation  allowance at
December 31, 2004 and 2005.

      The components of the net deferred tax asset of December 31, 2004 and 2005
consists of the following:

(16) Contingencies

      On September 30, 1998, the Company filed a multi-count  complaint  against
Manuel P. Asensio,  Asensio & Company,  Inc.  ("Asensio").  The action  included
claims of defamation,  disparagement,  tortuous  interference  with existing and
prospective  business  relations and conspiracy,  arising out of Asensio's false
and defamatory  statements.  The complaint  further alleged that Asensio defamed
and  disparaged  the Company in  furtherance  of a  manipulative,  deceptive and
unlawful  short-selling  scheme in August and September,  1998. In 1999, Asensio
filed an answer and  counterclaim  alleging that in response to Asensio's strong
sell  recommendation  and other  press  releases,  the Company  made  defamatory
statements  about Asensio.  The Company  denied the material  allegations of the
counterclaim.  In July 2000,  following  dismissal in federal  court for lack of
subject  matter  jurisdiction,   the  Company  transferred  the  action  to  the
Pennsylvania  State  Court.  In March  2001,  the  defendants  responded  to the
complaints as amended and a trial  commenced on January 30, 2002. A jury verdict
disallowed the claims  against the  defendants for defamation and  disparagement
and the court  granted the Company a directed  verdict on the  counterclaim.  On
July 2, 2002 the Court entered an order granting the Company a new trial against
Asensio for  defamation  and  disparagement.  Thereafter,  Asensio  appealed the
granting of a new trial to the  Superior  Court of  Pennsylvania.  The  Superior
Court of  Pennsylvania  has denied  Asensio's  appeal.  Asensio  petitioned  the
Supreme Court of Pennsylvania for allowance of an appeal,  which was denied. The
Company  now  anticipates  the  scheduling  of a new trial  against  Asensio for
defamation and disparagement in the Philadelphia Common Pleas Court.


                                      F-56


      In June 2002, a former ME/CFS clinical trial patient and her husband filed
a claim in the  Superior  Court of New  Jersey,  Middlesex  County,  against the
Company,  one of its clinical trial  investigators  and others alleging that she
was harmed in the ME/CFS  clinical trial as a result of negligence and breach of
warranties.  On June 25, 2004 all claims against the Company were dismissed with
prejudice.  The former  ME/CFS  clinical  trial patient and her husband have now
appealed  the  dismissal  of their  claims  to the New  Jersey  Superior  Court,
Apellate  Division,  who upheld the dismissal of all claims  against the Company
and the matter is now concluded.

      In June 2002, a former  ME/CFS  clinical  trial patient in Belgium filed a
claim in Belgium,  against  Hemispherx  Biopharma  Europe,  NV/SA, the Company's
Belgian  subsidiary,  and  one of the  Company's  clinical  trial  investigators
alleging that she was harmed in the Belgium ME/CFS clinical trial as a result of
negligence and breach of warranties.  The Company  believes the claim is without
merit and the Company is  defending  the claim  against the Company  through its
product liability insurance carrier.

      In December  2004,  the Company  filed a  multicount  complaint in federal
court  (Southern  District of Florida)  against a  conspiratorial  group,  which
includes  Bioclones,  seeking to illegally  manipulate its stock for purposes of
bringing about a hostile  takeover of Hemispherx.  The lawsuit  alleges that the
conspiratorial  group  commenced  with a plan to seize  control  of its cash and
proprietary  assets by an illegal  campaign  to drive  down its stock  price and
publish disparaging reports on the Company's management and current fiduciaries.
The lawsuit seeks monetary damages from each member of the conspiratorial  group
as well as injunctions  preventing further recurrences of their misconduct.  The
conspiratorial  group  includes  Bioclones,   a  privately  held  South  African
Biopharmaceutical  company that collaborated with the Company (see Note 13), and
Johannesburg  Consolidated  Investments,  a  South  African  corporation,  Cyril
Donninger,  R. B.  Kebble,  H. C.  Buitendag,  Bart  Goemaere,  and John Doe(s).
Bioclones,  Johannesburg Consolidated Investments, Cyril Donninger, R. B. Kebble
and H.C. Buitendag filed a motion to dismiss the complaint, which was granted by
the court.  The Company is in the process of appealing this decision to the 11th
federal circuit court of appeals.

      On January 10, 2005,  the Company  initiated a  multicount  lawsuit in the
United States District Court for the Eastern  District of  Pennsylvania  seeking
injunctive  relief and damages against a conspiratorial  group, many of whom are
foreign  nationals or companies  located outside the United States alleging that
the conspiratorial group has engaged in secret meetings,  market  manipulations,
fraudulent  misrepresentations,  utilization  of foreign  accounts  and  foreign
secrecy laws all in furtherance of an illegal scheme to take over Hemispherx and
enrich  themselves  at the  expense  of  Hemispherx's  public  shareholders.  On
February  18, 2005 the Company  filed an amended  complaint  in the same lawsuit
joining Redlabs,  USA, Inc. as a defendant with the existing  defendants  R.E.D.
Laboratories,  N.V./S.A.,  Bart Goemaere,  Jan Goemaere,  Dr. Kenny De Meirleir,
Kenneth Schepmans,  Johan Goossens,  Lieven Vansacker and John Does. Pursuant to
an agreement in which R.E.D.  Laboratories,  N.V./S.A.  and Dr. Kenny DeMeirleir
agreed not to  participate  in a hostile  takeover of Hemispherx for a period of
five years, R.E.D.  Laboratories,  N.V./S.A.  and Dr. Kenny DeMeirleir have been
dismissed as defendants in the litigation.  The litigation is proceeding against
the remaining defendants.

We loaned  $60,000 to Ransom W.  Etheridge  in November  2001 for the purpose of
exercising  15,000 class A redeemable  warrants.  This loan bears interest at 6%
per annum.  This loan was granted prior to the  enactment of the Sarbanes  Oxley
Act of 2002 prohibiting such  transactions.  In lieu of granting Mr. Etheridge a
bonus for outstanding legal work performance on behalf of the Company, the Board
of Directors forgave the loan and accrued interest on February 24, 2006.

      Richard  Piani,  a  Director,  lives in Paris,  France  and  assisted  the
Company's European  subsidiaries in their dealings with medical institutions and
the European  Medical  Evaluation  Authority.  Mr. Piani assisted the Company in
establishing clinical trial protocols as well as performed other scientific work
for the Company.  The services  provided by Mr.  Piani  terminated  in September
2003.  For these  services,  Mr. Piani was paid an aggregate of $100,100 for the
year ended December 31, 2003.

      The Company paid $18,800, and $7,600 for the years ended December 31, 2003
and 2004,  respectively  to Carter  Realty for the rent of property  used by the
Company  at  various  times in years 2003 and 2004.  The  property  was owned by
others,  but was acquired in late 2004 by Retreat House, LLC, an entity in which
the children of William A. Carter have a beneficial  interest.  The Company Paid
Retreat House, LLC $54,000 for the use of the property at various times in 2005.

Group of Branchburg,  New Jersey for R. Douglas Hulse, an Executive  Director of
The Sage Group, to serve as President and Chief Operating Officer of the Company
(See Notes 3 and 11 for additional information concerning this agreement).

(18) Concentrations of credit risk


                                      F-58


      Financial   instruments,   which   potentially   subject  the  Company  to
concentrations  of credit risk,  consist  principally of cash, cash equivalents,
investments  and  accounts   receivable.   The  Company  places  its  cash  with
high-quality financial  institutions.  At times, such amount may be in excess of
Federal Deposit Insurance Corporation insurance limits of $100,000.

      Sales to three large wholesalers represented  approximately 74% and 80% of
the  Company's  total  sales for the years  ended  December  31,  2004 and 2005,
respectively.

See Note 2 for restated  year end results for the year ended  December 31, 2004.
As  discussed  in Note 2, the Company  will file its  quarterly  reports on Form
10-Q/A  for the  quarterly  periods  ended  March 31,  2005,  June 30,  2005 and
September  30, 2005,  which will  include the quarters  ended in 2004 as soon as
practicable.

(1)   During the first quarter 2004, the Company recorded stock  compensation of
      $1,769,000  (See Note 9(b)) and during the third quarter 2004, the Company
      recorded stock compensation of $231,000.

(2)   The Company  re-evaluated  the accounting  for the March 2003,  July 2003,
      October 2003,  January 2004 and July 2004 Debentures  (collectively,  "the
      Debentures") to determine whether the embedded conversion options required
      bifurcation  and fair value  accounting in accordance  with FASB Statement
      No. 133,  "Accounting for Derivative  Instruments and Hedging Activities",
      and EITF 00-19,  "Accounting for Derivative Financial  Instruments Indexed
      to, and  Potentially  Settled  in a  Company's  Own  Stock".  The  Company
      concluded  that  bifurcation  was not  required and that EITF 00-27 should
      have been applied.  The Company did initially apply EITF 00-27, however as
      part of performing an analysis on the  guidelines  set forth in EITF 00-27
      it was  determined  that the initial  accounting  treatment and subsequent
      price resets for the Debentures that were originally applied and reflected
      in  the  financial  statements.   To  properly  account  for  the  initial
      calculation of the discount and the conversion price resets triggered upon
      the issuance of the issuance of the October 2003  Debenture and the August
      2004 Private Placement (See Notes 8 & 9 for more details on these resets),
      it was  determined,  under guidance from EITF 00-27 that the debt discount
      should be restated for the Debentures.


                                      F-59


(3)   The estimation of fair value  ascribed to and the accounting  treatment of
      the investment banking fees paid to Cardinal Capital,  LLC ("Cardinal") in
      connection with the Debenture  issuances,  at inception,  was inaccurately
      reflected in the financial statements included in our Quarterly reports on
      Form 10-Q and that,  therefore,  a restatement of our financial statements
      for the periods  referenced  above was required.  In  connection  with the
      initial  recording of the Debentures  mentioned  above,  it was determined
      that the fair value of the warrants issued as investment banking fees paid
      to  Cardinal,  be  accounted  for  as  a  discount  to  Debentures.  These
      investment banking fees should have been capitalized as deferred financing
      costs and amortized over the life of the Debentures or charged to earnings
      on the earlier conversion thereof. In addition, the initial calculation of
      the  fair  value  of the  warrants  issued  to  Cardinal  as a part of the
      Debenture issuances was determined to have been applied incorrectly at the
      time of issuance.

(4)   The accounting  treatment set forth is FASB Statement No. 123, "Accounting
      for Stock-Based Compensation", for the issuance of the June 2008, May 2009
      and June 2009 Warrants (collectively "the Warrants") (See Note 8) that was
      originally interpreted and reflected in the financial statements,  was not
      correctly  applied.  The warrants  issued as  incentive to exercise  prior
      warrant  issuances  are  reflected  as a  deemed  dividend  at the date of
      issuance,   where  previously  these  warrants  were  either  recorded  as
      additional debt discount or as a financing charge at date of issuance.

                                      2005

                                      F-60


(1)   The Company  re-evaluated  the accounting  for the March 2003,  July 2003,
      October 2003,  January 2004 and July 2004 Debentures  (collectively,  "the
      Debentures") to determine whether the embedded conversion options required
      bifurcation  and fair value  accounting in accordance  with FASB Statement
      No. 133,  "Accounting for Derivative  Instruments and Hedging Activities",
      and EITF 00-19,  "Accounting for Derivative Financial  Instruments Indexed
      to, and  Potentially  Settled  in a  Company's  Own  Stock".  The  Company
      concluded  that  bifurcation  was not  required and that EITF 00-27 should
      have been applied.  The Company did initially apply EITF 00-27, however as
      a part of performing an analysis on the guidelines set forth in EITF 00-27
      it was  determined  that the initial  accounting  treatment and subsequent
      price resets for the Debentures that were originally applied and reflected
      in  the  financial  statements.   To  properly  account  for  the  initial
      calculation of the discount and the conversion price resets triggered upon
      the issuance of the issuance of the October 2003  Debenture and the August
      2004 Private Placement (See Notes 8 & 9 for more details on these resets),
      it was  determined,  under guidance from EITF 00-27 that the debt discount
      should be restated for the Debentures.

(2)   The estimation of fair value  ascribed to and the accounting  treatment of
      the investment banking fees paid to Cardinal Capital,  LLC ("Cardinal") in
      connection with the Debenture  issuances,  at inception,  was inaccurately
      reflected in the financial statements included in our Quarterly Reports on
      Form 10-Q and that,  therefore,  a restatement of our financial statements
      for the periods  referenced  above was required.  In  connection  with the

      on the earlier conversion thereof. In addition, the initial calculation of
      the  fair  value  of the  warrants  issued  to  Cardinal  as a part of the
      Debenture issuances was determined to have been applied incorrectly at the
      time of issuance.

(3)   The Company  incorrectly  recorded  $241,000 in other  income in the third
      quarter  2005  related to the  termination  of the MOU notice  received by
      Astellas.  This  amount  was  subsequently  adjusted  back  to an  accrued
      liability  as of December  31,  2005,  as the  agreement  has not yet been
      formally terminated.

(4)   The  accounting for certain  warrants and options issued to  non-employees
      and our  interpretation and application of FASB No. 123 was not correct in
      2005.

(20) Subsequent Events

On February 8, 2006, the Company  executed a Manufacturing  and Safety Agreement
with  Hyaluron,  Inc.  ("Hyaluron")  of  Burlington,   Massachusetts,   for  the
formulation,  packaging and labeling of Alferon N Injection(R).  Pursuant to the
Agreement,  the Company  will supply raw  materials in  sufficient  quantity and
provide any pertinent information to the project.

On March 21, 2006,  the debenture  holders  converted  $500,000 of the July 2004
debenture into 240,385 shares of common stock.


                                      F-61


The  Company  failed  to  timely  file its  Annual  Report on Form 10-K with the
Securities and Exchange Commission pursuant to the 1934 Act, and therefore,  was
in violation of its covenant to timely file within its debenture agreements. The
Company  obtained a waiver  letter  from its  debenture  holders  regarding  the
failure  to meet  this  covenant.  In  addition,  as a result  of the  Company's
inability  to timely  file its  annual  report  on Form 10-K for the year  ended
December 31, 2005, the Company currently is subject to liquidated  damages until
such time as the shares  issuable  upon  conversion  of and  interest  under the
debentures,  and  shares  issuable  upon  exercise  of the  warrants  are  again
registered  for public  resale or  eligible  for resale  pursuant to Rule 144(k)
under the Securities Act. The Company  anticipates the liquidated damages not to
exceed $250,000.

During 2006, the Company has issued an additional  4,913,669 shares for proceeds
of  $11,979,994  which  completes the terms of the July 8, 2005,  Fusion Capital
agreement (see Note 9(d)).

On April 3, 2006,  the Company  received a notice from the staff of The American
Stock Exchange  ("AMEX")  indicating  that it is not in compliance with Sections
134 and 1101 of the AMEX  Company  Guide and its  listing  agreement  due to the
Company's  failure  to file its annual  report on Form 10-K for the fiscal  year
ended December 31, 2005 with audited financial statements on a timely basis. The
AMEX has granted an extension of the listing of the Company's common stock until
June 30, 2006, provided that the Company files its Form 10-K for 2005 by June 2,
2006 and provided  that it files its Form 10-Q for the first  quarter of 2006 by
June 30,  2006.  During the  extension  period,  the Company  will be subject to
periodic review by AMEX staff. If the Company fails to meet any of the foregoing
deadlines, the AMEX has indicated that it will begin delisting proceedings.

On April 12, 2006, the Company  entered into a Common Stock  Purchase  Agreement
("Purchase  Agreement")  with  Fusion  Capital.  Pursuant  to the  terms  of the
Purchase Agreement, Fusion Capital has agreed to purchase from the Company up to
$50,000,000  of common  stock over a period of  approximately  twenty-five  (25)
months. Pursuant to the terms of the Registration Rights Agreement,  dated as of
April 12, 2006, we agreed to file a registration  statement  (the  "Registration
Statement")  with the Securities  and Exchange  Commission on or before June 30,
2006 covering the shares which are issued to or may be issued to Fusion  Capital
under the Purchase Agreement.  Once the Registration Statement has been declared
effective,  each trading day during the term of the  Purchase  Agreement we have
the right to sell to Fusion  Capital up to $100,000 of our common  stock on such
date or the  arithmetic  average of the three lowest closing trade prices of the
common stock during the  immediately  proceeding  12 trading day period.  At our
