                                   FORM 10-Q/A
                                EXPLANATORY NOTE

This amendment on Form 10-Q/A amends our Quarterly Report for the third quarter
of 2005 initially filed with the Securities and Exchange Commission ("SEC") on
November 9, 2005 (the "original Form 10-Q"). It is being filed to reflect the
restatement (the "Restatements") of our consolidated balance sheets and related
consolidated statements of operations, cash flows and stockholders' equity and
comprehensive loss as of and for the three and nine months ended September 30,
2005 and 2004, as discussed in Note 2 to the consolidated financial statements.

No attempt has been made in this Form 10-Q/A to modify or update disclosures in
original Form 10-Q except as required to address the Restatements. Except as
described below, this Form 10-Q/A does not reflect events occurring after the
filing of the original Form 10-Q or modify or update any related disclosures.
Information not affected by the amendment is unchanged and reflects the
disclosure made at the time of the filing of the original Form 10-Q with the
SEC. Accordingly, this Form 10-Q/A should be read in conjunction with the
original Form 10-Q and our filings made with the SEC subsequent to the filing of
the original Form 10-Q, including any amendments to those filings.

In accordance with Rule 12b-15 promulgated under the Securities and Exchange Act
of 1934, as amended, the complete texts of Part I, Items 1, 2 and 4 are set
forth herein, including those portions of the text that have not been amended
from that set forth in the original Form 10-Q. The only changes to the text in
Part I, Items 1, 2 and 4 of the original Form 10-Q are as follows:

Part I

         Item 1.

                  o   The financial statements, including the footnotes, have
                      been revised to reflect the changes required by the
                      Restatements.
                  o   A new footnote (Note 2) has been added to describe the
                      Restatements and the other footnotes have been revised to
                      conform with the footnote presentation and disclosure in
                      our Form 10-Q for the quarter ended March 31, 2006 (which
                      was filed with the SEC on June 30, 2006).
                  o   Note 3: Stock based compensation was revised to include
                      the pro forma effect on the Company's net loss and loss
                      per share had compensation cost for the Company's option
                      plans been determined for the three months ended June 30,
                      2004 and 2005.
                  o   Note 6: Revenue and Licensing Fee Income was changed to
                      reflect the restatement due to the Company incorrectly
                      recording $241,000 in other income related to the
                      termination of the Memorandum of Understanding notice
                      received by Astellas.
                  o   The paragraph concerning the closing of the August 2004
                      Private Placement and its triggering of anti-dilution
                      provisions within Note 9: Equity Financing was removed to
                      reflect the changes required by the restatements.

         Item 2.

                  o   An additional critical accounting policy titled
                      "Convertible Debentures" has been added.
                  o   The following subsections in both "Three months ended
                      September 30, 2005 versus Three months ended September 30,
                      2004" and "Nine months ended September 30, 2005 versus
                      Nine months ended September 30, 2004" have been revised as
                      a result of the Restatements: "Net Loss" (which is now
                      "Net Loss Applicable to Common Stockholders"), "General
                      and Administrative Expenses" and "Interest Expense and
                      Financing Costs." In addition, a subsection titled "Deemed
                      Dividend" has been added in the three and nine month
                      comparisons.


                                       2


                  o   An additional risk factor titled "We reported material
                      weaknesses in our internal control over financial
                      reporting that, if not remedied, could adversely affect
                      our internal controls" has been added.
                  o   The risk factor "We may continue to incur substantial
                      losses and our future profitability is uncertain" has been
                      revised to correct the accumulated deficit as a result of
                      the Restatements.
                  o   The table within "Liquidity and Capital Resources"
                      disclosing information concerning debenture installment
                      payments and conversions to common Shares was changed to
                      conform to Note 8 within the financial statements.

         Item 4.

                  o   This Item has been revised in its entirety due to the
                      Restatements.

Summary of 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 the 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. We 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
annual financial statements and quarterly results of operations (unaudited)
included in our annual report on Form 10-K/A for the period ending December 31,
2005, which was filed on June 5, 2006 and further amended Footnote 19, Quarterly
Results of Operations (unaudited), to those financials in our Annual Report on
Form 10-K/A-2 for the fiscal year ended December 31, 2005, which was filed on
July 31, 2006.

In addition, we restated: (i) our condensed consolidated unaudited interim
financial statements for the quarter ended March 31, 2005 included in our
quarterly report on Form 10-Q for the quarter ended March 31, 2006, which was
filed on June 30, 2006; (ii) our condensed consolidated unaudited interim
financial statements for the quarter and six months ended June 30, 2005 and
2004, included in our June 30, 2005 quarterly report on Form 10-Q/A filed on
July 31, 2006, and (iii) the condensed consolidated unaudited interim financial
statements for quarter and nine months ended September 30, 2005 and 2004
included in this quarterly report on Form 10-Q/A. The modifications in the
restated financial statements relate to non-cash charges that do not affect our
revenues, cash flows from operations or liquidity.

                   HEMISPHERx BIOPHARMA, INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of
Hemispherx BioPharma, Inc., a Delaware corporation and its subsidiaries. All
significant intercompany accounts and transactions have been eliminated.

In the opinion of management, all adjustments necessary for a fair presentation
of such consolidated financial statements have been included. Such adjustments
consist of normal recurring items. Interim results are not necessarily
indicative of results for a full year.

The interim consolidated financial statements and notes thereto are presented as
permitted by the Securities and Exchange Commission (SEC), and do not contain
certain information which will be included in our annual consolidated financial
statements and notes thereto.

These consolidated financial statements should be read in conjunction with our
consolidated financial statements included in our annual report on Form 10-K/A-2
for the year ended December 31, 2005, as filed with the SEC on July 31, 2006.

Note 2: Restatements

In 2003 and 2004, the Company 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. The Company's convertible
debenture transactions were reported within the Company's previously filed
financial statements for the years ended December 31, 2003 and 2004. After an
extensive review and consultation with the the Company's independent registered
public accountants and the Company's audit committee, it was determined that the
Company must restate its historical financial statements for the years ended
December 31, 2003 and 2004 as well as the interim financial statements for 2003,
2004, and 2005. The Company 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, the Company restated its annual financial statements and
quarterly results of operations (unaudited) included in its annual report on
Form 10-K/A for the period ending December 31, 2005, which was filed on June 5,
2006 and further amended Footnote 19, Quarterly Results of Operations
(unaudited), to those financials in its Annual Report on Form 10-K/A-2 for the
fiscal year ended December 31, 2005, which was filed on July 31, 2006.

In addition, the Company restated: (i) its condensed consolidated unaudited
interim financial statements for the quarter ended March 31, 2005 included in
its quarterly report on Form 10-Q for the quarter ended March 31, 2006, which
was filed on June 30, 2006; (ii) its condensed consolidated unaudited interim
financial statements for the quarter and six months ended June 30, 2005 and
2004, contained in our June 30, 2005 quarterly report on Form 10-Q/A filed on
July 31, 2006, and (iii) the condensed consolidated unaudited interim financial
statements for quarter and nine months ended September 30, 2005 and 2004
included in this quarterly report on Form 10-Q/A. The modifications in the
restated financial statements relate to non-cash charges that do not affect its
revenues, cash flows from operations or liquidity.

(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


                                       10


      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 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 three months ended September 30,
      2004 and 2005 by approximately $2,903,000 and $611,000 or $0.06 and $0.01
      per share, respectively, and decrease the net loss applicable to common
      stockholders for the nine months ended September 30, 2004 and 2005 by
      approximately $7,237,000 and $1,402,000, or $0.17 and $0.03 per share,
      respectively.

(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 increase the
      net loss applicable to common stockholders for the three months ended
      September 30, 2004 and 2005 by approximately $48,000 and $48,000 or $0.00
      and $0.00 per share respectively, and increase the net loss applicable to
      common stockholders for the nine months ended September 30, 2004 and 2005
      by approximately $233,000 and $135,000 or $0.00 and $0.00 per share,
      respectively.

(c)   The accounting treatment for certain warrants and options issued to
      non-employees and our interpretation and application of FASB No. 123 was
      not correct in 2005. The total impact of this restatement on the Company's
      settlement of operations was to increase the net loss for the three months
      ended September 30, 2005, by approximately $78,000 or $0.00 per share and
      an increase in the net loss applicable to common stockholders for the nine
      months ended September 30, 2005 by approximately $236,000 or $0.00 per
      share.


                                       11


(d)   The accounting treatment set forth in FASB Statement No. 123, "Accounting
      for Stock-Based Compensation", for the issuance of the May 2009 Warrants
      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, and in the Company's Quarterly Reports on Form 10-Q
      during the quarterly periods in fiscal 2003, 2004 and 2005 was not
      correctly applied and as a result a restatement of our financial
      statements for the periods 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 the net loss applicable to
      common stock holders for the three and nine months ended September 30,
      2004 by $1,676,000 and $4,031,000 or $0.04 and $0.09 per share,
      respectively.

(e)   The Company incorrectly recorded $241,000 in other income Memorandum of
      Understanding ("MOU") 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 September 30, 2005, as the
      agreement had not yet been formally terminated. The total impact of this
      restatement on our statement of operations was to increase the net loss
      for the three and nine months ended September 30, 2005, by approximately
      $241,000 or $0.00 and $0.00 per share, respectively.

As a result of the corrections of the errors described above, the Company has
restated its financial statements for this Quarterly Report on Form 10-Q/A as
follows:

Note 4: INVESTMENT IN UNCONSOLIDATED AFFILIATES

Investments include an equity investment of $35,000 in Chronix Biomedical
("Chronix"). Chronix focuses upon the development of diagnostics for chronic
diseases. This initial investment was made in May 31, 2000 by the issuance of
50,000 shares of the Company's common stock from the treasury. On October 12,
2000, the Company issued an additional 50,000 shares of its common stock and on
March 7, 2001 the Company issued 12,000 more shares of its common stock from the
treasury to Chronix for an aggregate equity investment of $700,000. The
percentage ownership in Chronix is approximately 5.4% and is accounted for under
the cost method of accounting. During the quarter ended December 31, 2002, the
Company recorded a non-cash charge of $292,000 with respect to the investment in
Chronix. The Company recorded an additional non-cash charge of $373,000 during
the quarter ended September 30, 2004, due to evidence of a further decline in
Chronix's market value. This impairment reduces the carrying value to reflect a
permanent decline in Chronix's market value based on its then proposed
investment offerings.

Note 5: 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:

The Company's reserve for R&D utilization as of September 30, 2005, totaled
$100,000 for Alferon N Injections(R) finished goods. The FDA recently extended
the shelf-life of Alferon N Injection(R) to 24 months. The reserve represents
product that may not be sold prior to expiration of its shelf-life.

NOTE 6:  REVENUE AND LICENSING FEE INCOME

The Company executed a Memorandum of Understanding (MOU) in January 2004 with
Astellas Pharma ("Astellas"), formally Fujisawa Deutschland GmbH, ("Fuji") 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 believes that it now is 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. The
company has recorded the remaining 200,000 Euros as an accrued liability as of
September 30, 2005. Fuji and Yamanouchi Pharmaceutical Co., Ltd. ("Yamanouchi")
have reached a definitive agreement upon the terms of their merger, which took
effect on April 1, 2005. Yamanouchi will be the surviving company and Fuji will
be dissolved. The combinded company name will be Astellas Pharma, Inc.

Revenues for non-refundable license fees are recognized under the Performance
Method-Expected Revenue. This method considers the total amount of expected
revenue during the performance period, but limits the amount of revenue
recognized in a period to total non-refundable cash received to date. This
limitation is appropriate because future milestone payments are contingent on
future events.

Upon receipt, the upfront non-refundable payment is deferred. The non-refundable
upfront payments plus non-refundable payments arising from the achievement of
defined milestones are recognized as revenue over the performance period based
on the lesser of (a) percentage of completion or (b)non-refundable cash earned
(including the upfront payment).

This method requires the computation of a ratio of cost incurred to date to
total expected costs and then apply that ratio to total expected revenue. The
amount of revenue recognized is limited to the total non-refundable cash
received to date.

During the period ended September 30, 2005, the Company did not receive any
grant monies from local, state and or Federal Agencies.

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.

Revenue from the sale of product 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.

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

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 have 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

                        Buildings           2,893,000
                                          -----------

                        Total cost        $ 3,316,000

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).


                                       19


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.

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.


                                       20


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 three months ended September 30,
2004 and 2005, with regard to the July 2003 Debentures of approximately $130,000
and $0, respectively.

The Company recorded financing costs for the nine months ended September 30,
2004 and 2005, with regard to the July 2003 Debentures of approximately
$1,496,000 and $0, 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. 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.

Pursuant to the Company's agreement with the holders, 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.


                                       21


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 Note 13).

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, 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.

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
March 31, 2005 have been accounted for as advances receivable and are reflected
as such on the accompanying balance sheet as of March 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.


                                       22


As of September 30, 2005, the investors had converted $2,071,179 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 three months ended September 30,
2004 and 2005, with regard to the October 2003 Debentures of $371,000 and
$124,000, respectively. Interest expense for the three months ended September
30, 2004 and 2005, with regard to the October 2003 Debentures was approximately
$45,000 and $31,000, respectively.

The Company recorded financing costs for the nine months ended September 30,
2004 and 2005, with regard to the October 2003 Debentures of $996,000 and
$865,000, respectively. Interest expense for the nine months ended September 30,
2004 and 2005, with regard to the October 2003 Debentures was approximately
$84,000 and $93,000, 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).

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 Note 13).


                                       23


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, 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.

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.


                                       24


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.

As of September 30, 2005, the Company has made aggregate installment payments of
$1,888,888 and the investors have converted an aggregate of $139,150 of
principal amount of the January 2004 Debentures into 1,094,149 and 55,000 shares
of common stock, respectively. During the nine months ended September 30, 2005,
the investors converted approximately $1,111,111_of principal amount of the
January 2004 Debentures into 735,217 shares of common stock. The remaining
principal on these Debentures was $1,972,000 as of September 30, 2005.

The Company recorded financing costs for the three months ended September 30,
2004 and 2005 with regard to the January 2004 Debentures of $216,000 and
$236,000, respectively. Interest expense for the three months ended September
30, 2004 and 2005, with regard to the January 2004 Debentures was approximately
$54,000 and $25,000, respectively.

The Company recorded financing costs for the nine months ended September 30,
2004 and 2005 with regard to the January 2004 Debentures of $483,000 and
$746,000, respectively. Interest expense for the nine months ended September 30,
2004 and 2005, with regard to the January 2004 Debentures was approximately
$157,000 and $117,000, 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.


                                       25


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.

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 Note 13).

The remaining principal amount on these debentures was $1,500,000 as of
September 30, 2005.

The Company recorded financing costs for the three months ended September 30,
2004 and 2005 with regard to the July 2004 Debentures of $124,000_and $113,000,
respectively. Interest expense for the three months ended September 30, 2004 and
2005, with regard to the January 2004 Debentures was approximately $31,000_ and
$27,000, respectively

The Company recorded financing costs for the nine months ended September 30,
2004 and 2005 with regard to the July 2004 Debentures of $124,000_and $361,000,
respectively. Interest expense for the nine months ended September 30, 2004 and
2005, with regard to the January 2004 Debentures was approximately $31,000_ and
$87,000, respectively.

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 3,759,094 shares at December 31, 2004 and September 30, 2005,
respectively.

Collateral and Financial Covenants

The Company paid $1,300,000 in 2003 into the debenture cash collateral account

Note 9: EQUITY FINANCING

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 has agreed to register all of the foregoing shares and shares issuable
upon exercise of the above mentioned warrants for public resale.

On July 8, 2005, the Company entered into a common stock purchase agreement with
Fusion Capital Fund II, LLC, 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, the Company may elect to sell less of the Company's common
stock to Fusion Capital than the daily amount and the Company 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
Company's common stock is less than $1.00.

Pursuant to the agreement with Fusion Capital, the Company has registered for
public sale by Fusion Capital up to 10,795,597 shares of the Company's 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
September 30, 2005 Fusion Capital has purchased 548,707 shares amounting to
$789,994 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 conjuction 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 price at which the shares are being purchased by Fusion Capital and the
denominator of which is $20,000,000. As of September 30, 2005, Fusion Capital
was issued 16,301 shares towards this commitment fee.


                                       27


Note 10: EXECUTIVE COMPENSATION

In order to facilitate the Company's need to obtain financing and prior to our
stockholders approving an amendment to our corporate charter to increase the
number of authorized shares, Dr. Carter agreed to waive his right to exercise
certain warrants and options unless and until our stockholders approved an
increase in our 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 with an exercise price of $2.20
per share. This additional compensation was reviewed by an independent valuation
firm and found to be fair and reasonable within the context of total
compensation paid to chief executive officers of comparable biotechnology
companies.

In the quarter ended March 31, 2004, Dr. Carter was awarded an additional bonus
of $99,481 by the Compensation Committee. In addition, The Company recorded a
non-cash stock compensation charge of $1,769,000 during the first quarter 2004
resulting from warrants issued to Dr. Carter in 2003 that vested upon the
execution of the second ISI asset closing on March 17, 2004. This was determined
by subtracting the exercise price from the stock closing price on March 17, 2004
and multiplying the result by the number of warrants.

Note 11: EQUITY INCENTIVE PLAN

The Equity Incentive Plan authorizes the grant of non-qualified and incentive
stock options, stock appreciation rights, restricted stock and other stock
awards. 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 of directors may select. A
maximum of 8,000,000 shares of common stock is reserved for potential issuance.
Unless sooner terminated, the Equity Incentive Plan will continue in effect for
a period of 10 years from its effective date. As of September 30, 2005, the
Company has granted 221,895 options to directors, officers and employees
pursuant to the terms of this plan.

Note 12: COMMITMENTS

In May 2005, the Company committed to purchase lab equipment related to the
manufacture of Ampligen(R) raw material in the amount of approximately $628,000.
The Company paid the initial deposit of approximately $31,400 in May 2005.

On September 9, 2005, the Company signed a Letter of Intent ("LOI") with
Hollister-Stier Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for
the contract manufacturing of Ampligen(R). In November 2005, the Company paid
$100,000 upon executing the LOI in order to initiate the manufacturing project.
The LOI shall remain in full force and effect for 90 calendar days or until a
definitive agreement is reached. Based on the LOI, Hollister-Stier has agreed to
formulate and bottle Ampligen(R) using raw materials received from the Company.
The Company has an executed confidentiality agreement in place and; therefore,
has commenced the preliminary transfer of the manufacturing technology to
Hollister-Stier. The Company's decision to transfer relevant manufacturing
technology absent of an executed agreement, was done in part to expedite the
eventual manufacture of Ampligen(R) by Hollister-Stier. If the Company is unable
to negotiate and finalize an agreement with Hollister-Stier, in a timely manner
its plans to file an NDA for Ampligen(R) and, eventually, to market and sell
Ampligen(R) will be delayed.


                                       28


Note 13: SUBSEQUENT EVENTS

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 exercise 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.

                                    Overview

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. After almost 30 years, 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, and our corporate offices are in
Philadelphia, PA.


                                       29


Our 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. 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.
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. 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
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 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.


                                       30


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. 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 is a dsRNA which currently is undergoing testing in this animal model.

For more detailed information concerning our Research and Development
activities, please refer to Item 2. "Management's Discussion and Analysis on
Results of Operations - Research and Development Costs."

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 on an undiscounted cash
basis to support the realizability of our respective capitalized cost. 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 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.

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.

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 the our independent registered public accountants and our


                                       31


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. We 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
annual financial statements and quarterly results of operations (unaudited)
included in our annual report on Form 10-K/A for the period ending December 31,
2005, which was filed on June 5, 2006 and further amended Footnote 19, Quarterly
Results of Operations (unaudited), to those financials in our Annual Report on
Form 10-K/A-2 for the fiscal year ended December 31, 2005, which was filed on
July 31, 2006.

In addition, we restated: (i) our condensed consolidated unaudited interim
financial statements for the quarter ended March 31, 2005 included in our
quarterly report on Form 10-Q for the quarter ended March 31, 2006, which was
filed on June 30, 2006; (ii) our condensed consolidated unaudited interim
financial statements for the quarter and six months ended June 30, 2005 and
2004, contained in our June 30, 2005 quarterly report on Form 10-Q/A filed on
July 31, 2006, and (iii) the condensed consolidated unaudited interim financial
statements for quarter and nine months ended September 30, 2005 and 2004
included in this quarterly report on Form 10-Q/A. The modifications in the
restated financial statements relate to non-cash charges that do not affect our
revenues, cash flows from operations or liquidity.

(a)   Based on SEC guidance presented at the 2005 annual AICPA National
      Conference on current SEC and PCAOB developments, we re-evaluated our
      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 00-27: "Application of Issue
      No. 98-5 to Certain Convertible Instruments" ("EITF 00-27") should 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 for the Debentures and
      conversion price resets that was originally applied and reflected in the
      financial statements included in our Annual Reports on Form 10-K for the
      years ended December 31, 2004 and 2003, 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 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 October 2003 Debenture and
      the August 2004 Private Placement, 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 three
      months ended September 30, 2004 and 2005 by approximately $2,903,000 and
      $611,000, or $0.06 and $0.01 per share, respectively and decrease the net
      loss applicable to common stockholders for the nine months ended September
      30, 2004 and 2005 by approximately $7,237,000 and $1,402,000, or $0.17 and
      $0.03 per share, respectively.


                                       32


(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, 2004 and 2003, and our
      Quarterly reports on Form 10-Q during the quarterly periods in fiscal
      2003, 2004 and 2005 and as a result 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 be computed
      incorrectly at the time of issuance. The total impact of this restatement
      on our statement of operations was to increase the net loss applicable to
      common stockholders for the three months ended September 30, 2004 and
      2005, by approximately $48,000 and $48,000 or $0.00 and $0.00 per share
      respectively, and increase in the net loss applicable to common
      stockholders for the nine months ended September 30, 2004 and 2005 by
      approximately $233,000 and $135,000 or $0.00 and $0.00 per share,
      respectively.

(c)   The accounting treatment for certain warrants and options issued to
      non-employees and our interpretationand application of FASB No. 123 was
      not correct in 2005. The total impact of this restatement on our
      settlement of operations was to increase the net loss for the three months
      ended September 30, 2005, by approximately $78,000 or $0.00 per share and
      an increase in the net loss applicable to common stockholders for the nine
      months ended September 30, 2005 by approximately $236,000 or $0.00 per
      share.

(d)   The accounting treatment set forth in FASB Statement No. 123, "Accounting
      for Stock-Based Compensation", for the issuance of the May 2009 Warrants
      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, and in our Quarterly Reports on Form 10-Q during the
      quarterly periods in fiscal 2003, 2004 and 2005 was not correctly applied
      and as a result a restatement of our financial statements for the periods
      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 the net loss applicable to common stockholders
      for the three and nine months ended September 30, 2004 by $1,676,000 and
      $4,031,000, or $0.04 and $0.09 per share, respectively.

(e)   The Company incorrectly recorded $241,000 in other income in the third
      quarter 2005 related to the termination of the Memorandum of Understanding
      ("MOU") notice received by Astellas. This amount was subsequently adjusted
      back to an accrued liability as of September 30, 2005, as the agreement
      has not yet been formally terminated. The total impact of the restatement
      on our statement of operations was to increase the net loss for the three
      and nine months ended September 30, 2005, by approximately $241,000 or
      $0.00 and $0.00 per share, respectively.

As a result of the corrections of the errors described above, we, have restated
our financial statements within this Quarterly Report on Form 10-Q/A as follows:

                                  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 report. 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.


                                       37


            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. 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.
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.

            ALFERON N Injection(R). Although ALFERON N Injection(R) is approved
for marketing in the United States for the intralesional 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 intralesional 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.


                                       38


            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.

Although preliminary in vitro testing indicates that Ampligen(R) enhances the
effectiveness of different drug combinations on avain 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 avain
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
September 30, 2005 our accumulated deficit, as restated, was approximately
$144,174,000. 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.


                                       39


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 September 30, 2005, we had approximately $11,632,000
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. However, 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.

            Under the common stock purchase agreement signed with Fusion Capital
on July 8, 2005, we only have the right to receive $40,000 per trading day
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 our common stock
increases (For a more detailed description of the terms of this agreement, see
the agreement filed as an exhibit to our Current Report on Form 8-K filed with
the SEC on July 11, 2005). Fusion Capital shall not have the right nor the
obligation to purchase any shares of our common stock on any trading days that
the market price of our common stock is less than $1.00. Since we initially
registered 10,000,000 shares purchasable by Fusion Capital pursuant to the
common stock purchase agreement, the selling price of our common stock to Fusion
Capital will have to average at least $2.00 per share for us to receive the
maximum proceeds of $20.0 million without registering additional shares of
common stock. As of November 1, 2005, we need an average selling price of $2.11
per share for the remainder of the agreement to realize the $20,000,000 in
proceeds. The closing price of our stock was $2.84 on November 1, 2005. Subject
to approval by our board of directors, we have the right, but not the
obligation, to issue more than 10,000,000 shares to Fusion Capital. In the event
we elect to issue more than 10,000,000 shares, we will be required to file a new
registration statement and have it declared effective by the Securities and
Exchange Commission. In the event that we decide to issue more than 10,113,278
(19.99% of our outstanding shares of common stock as of the date of our
agreement), we would first be required to seek stockholder approval in order to
be in compliance with the American Stock Exchange Market rules.

            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. Specifically, Fusion Capital shall not have the right nor the
obligation to purchase any shares of our common stock on any trading days that
the market price of our common stock is less than $1.00. 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 $20.0 million under the common stock
purchase agreement with Fusion Capital, we may still need additional capital to
fully implement our business, operating and development plans. Should the
financing we require to sustain our working capital needs be unavailable or
prohibitively expensive when we require it, the consequences would materially
adversely affect our business, operating results, financial condition and
prospects.


                                       40


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.

            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.


                                       41


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 Bioclones (Proprietary), Ltd ("Bioclones"), Biovail Corporation
and Laboratorios Del Dr. Esteve S.A. may provide a sales force in South America,
Africa, United Kingdom, Australia and New Zealand, Canada, Spain and Portugal.
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 the hostile takeover of Hemispherx. This conspiratorial group
includes Bioclones and the potential legal action may adversely effect our
agreement with Bioclones and the potential for marketing and distribution
capacity in South America, Africa, United Kingdom, Australia and New Zealand.
See Item 1: "Legal Proceedings" in Part II - Other Information below for more
information.

            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.

            At present, we do not have any agreements with third parties for the
supply of any polymers for use in manufacturing Ampligen(R). 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 the 43,000 sq.
ft. wholly owned facility are already in compliance for Alferon N Injection(R)
manufacture), may delay certain steps in the commercialization process,
specifically a targeted NDA filing.


                                       42


            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.

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 key
components of our products and 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.

            In connection with settling various manufacturing infractions
previously noted by the FDA, Schering-Plough ("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 September 9, 2005, we signed a Letter of Intent ("LOI") with
Hollister-Stier Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for
the contract manufacturing of Ampligen(R). In November 2005, we paid $100,000
upon executing the LOI in order to initiate the manufacturing project. The LOI
shall remain in full force and effect for 90 calendar days or until a definitive
agreement is reached. The achievement of the initial objectives described in the
LOI, in combination with our polymer production facility under construction in
New Brunswick, N.J., may enable us to manufacture the raw materials for


                                       43


approximately 10,000 doses of Ampligen(R) per week. Based on the LOI,
Hollister-Stier has agreed to formulate and bottle Ampligen(R) using raw
materials received from us. We have an executed confidentiality agreement in
place and; therefore, have commenced the preliminary transfer of our
manufacturing technology to Hollister-Stier. Our decision to transfer relevant
manufacturing technology absent of an executed agreement, was done in part to
expedite the eventual manufacture of Ampligen(R) by Hollister-Stier. If we are
unable to negotiate and finalize an agreement with Hollister-Stier, in a timely
manner our plans to file an NDA for Ampligen(R) and, eventually, to market and
sell Ampligen(R) will be delayed.

            We have identified two other capable cGMP facilities in the US for
the manufacture of Ampligen(R) and obtained proposals from both. If either of
these two facilities are acceptable, we would be able to maintain a minimum of
two independent production sites. We are in the process of reviewing these other
proposals.

            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. We currently have 12,000 vials at
Hospira as work-in-progress inventory. We anticipate the conversion of these
vials to finished goods will be complete by mid-November 2005. Hospira is
ceasing the labeling and packaging of Alferon N Injection(R) as they are seeking
larger production runs for cost efficiency puposes. We have identified five new
potential contract manufacturers, obtained proposals from all five, and have
audited two, concerning the future formulation and packaging of Alferon N
Injection(R). If we are unable to secure a new facility within a reasonable
period of time to formulate and package ALFERON N Injection(R) at an acceptable
cost, our ability to sell ALFERON N Injection(R) and to generate profits
therefrom will be adversely affected.

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.


                                       44


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 Smithkline, 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.


                                       45


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 intralesional (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.

            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 May 8, 2008. 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.


                                       46


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 and 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. The restatements made to the
financial statements for the three and nine months ended September 30, 2004 and
2005 reflect weaknesses in disclosure controls and internal control over
financial reporting that existed as of the date of this report. Specifically,

      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.


                                       47


      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, from $0.42 per share to
$0.43 per share, for the year ended December 31, 2003, decreased our net loss
applicable to common stockholders by $0.07, from $0.53 per share to $0.46 per
share, for the year ended December 31, 2004, and decreased our net loss per
share applicable to common stockholders by $.00, $.01 and $.01 from $.07 per
share to $.07 per share, $.08 per share to $.07 per share and $.06 per share to
$.05 per share for the first, second and third quarters of 2005, respectively.

            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. 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. In addition, we have
established policies and procedures to include a detailed comprehensive review
of the underlying information supporting the amounts included within our
consolidated financial statements and disclosures including to assist in
ensuring: 1) clerical accuracy within our financial statements and disclosures,
2) financial statement groupings within our financial statements are accurate,
3) support utilized in preparation of the consolidated statement of cash flows
is accurate, and 4) equity transactions during the reporting period are complete
and accurate. We also engaged an additional accounting consultant in April 2006
to assist in initiating the implementation of these policies and procedures on a
going forward basis. 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.


                                       48


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 September 30, 2005, the price of our
common stock has ranged from $1.25 to $2.50 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.

            As of November 1, 2005, approximately 1,132,457 shares of our common
stock, constituted "restricted securities" as defined in Rule 144 under the
Securities Act of 1933, 402,798 of which are registered for public sale. Also,
we have registered 21,106,907 shares issuable (i) to Fusion Capital pursuant to
the common stock purchase agreement with Fusion Capital; (11) 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 the certain Warrants; and (v) upon exercise of certain other warrants.
In addition we will be registering an aggregate of 1,224,983 shares representing
135% of shares issuable upon exerice of the October 2009 Warrants and as
additional interest shares (resulting from the amendment to the Debentures.
Registration of the shares permits the sale of the shares in the open market or


                                       49


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 could cause the price
of our common stock to decline.

            The sale by Fusion Capital 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 could
depress the market price for our common stock. The issuance of shares to Fusion
Capital under the common stock purchase agreement dated July 8, 2005, 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 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 from the date theprospectus was filed.
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 under
this offering, 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 10.3% 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.

            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.

NEW ACCOUNTING PRONOUNCEMENTS

            In December 2004, the Financial Accounting Standards Board (FASB)
issued Statement of Financial Accounting Standards No. 123 (revised 2004) (FASB
123R), Shared-Based Payment. FASB 123R will require the Corporation to expense
share-based payments, including employee stock options, based on their fair
value. The Corporation is required to adopt the provisions of FASB 123R
effective as of the beginning of its next fiscal year that begins after June 15,
2005. FASB 123R provides alternative methods of adoption, which include
prospective application and a modified retroactive application. The Corporation
is currently evaluating the financial impact, including the available
alternative of adoption of FASB 123R.

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. See Note 9 in the accompanying
financial statements for more information concerning this transaction.
In connection with the Debenture agreements, we have outstanding letters of
credit of $1,000,000 as additional collateral.

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
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:


                                       51


Revenue

            Revenues for non-refundable license fees are recognized under the
Performance Method-Expected Revenue. This method considers the total amount of
expected revenue during the performance period, but limits the amount of revenue
recognized in a period to total non-refundable cash received to date. This
limitation is appropriate because future milestone payments are contingent on
future events.

            Upon receipt, the upfront non-refundable payment is deferred. The
non-refundable upfront payments plus non-refundable payments arising from the
achievement of defined milestones are recognized as revenue over the performance
period based on the lesser of (a) percentage of completion or (b) non-refundable
cash earned (including the upfront payment).

            This method requires the computation of a ratio of cost incurred to
date to total expected costs and then apply that ratio to total expected
revenue. The amount of revenue recognized is limited to the total non-refundable
cash received to date.

            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.

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 on an
undiscounted cash basis to support the realizability of our respective
capitalized cost. In addition, management's review addresses whether each patent
continues to fit into our strategic business plans.

Concentration of Credit Risk

            Financial instruments that potentially subject us to credit risks
consist of cash equivalents and accounts receivable.

            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 times, we have 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 September 30, 2005.

Convertible Debentures

            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


                                       52


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.

RESULTS OF OPERATIONS

Three months ended September 30, 2004 versus Three months ended September 30,
2005

Net Loss Applicable to Common Stockholders

            Our net loss applicable to common stockholders of $2,643,000 for the
three months ended September 30, 2005 was down $3,185,000 or 55% compared to the
same period in 2004. The reduction was primarily due to $415,000 in lower costs
associated with non-cash financing charges related to our convertible debentures
and related warrants as well as a deemed dividend of $1,676,000 recorded upon
the issuance of warrants to our debenture holders as incentive to exercise prior
warrant issuance. In addition, expenditures for manufacturing/production were
down $606,000 in 2005 reflecting the decrease in non-recurring expenses
associated with the ramping up of the New Brunswick facility for further
production of Alferon N Injection(R) in the third quarter of 2004.

            Net losses applicable to common stockholders were $(.05) per share
for current period versus $(.12) per share in the same period 2004.

Revenues

            Revenues for the three months ended September 30, 2005 were $271,000
as compared to revenues of $258,000 for the same period in 2004. Alferon N
Injection(R) sales were down $6,000 or 3% while Ampligen(R) sold under the cost
recovery clinical program was up $19,000 or 53%. 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.

            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 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).

            Human papillomavirus (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. The Centers for Disease Control and the
National Institute of Health, report that approximately 20 million people are
presently infected with HPV. Roughly 6.2 million Americans get a new genital HPV
infection each year. While the market for drugs treating HPV is extremely large,
there are many competing drugs.


                                       53


Production costs/cost of goods sold

            Our costs for production/cost of goods sold were down $606,000 for
the three months ended September 30, 2005 compared to the same period in 2004. A
decrease in production costs of approximately $590,000 is primarily due to
expenses incurred in the third quarter of 2004 related to preparing the New
Brunswick facility for the production of Alferon N Injection(R). There were no
such costs for Alferon N Injection(R) in the current quarter. We are now
concentrating on the completion of the construction and consolidation of the raw
material manufacturing within our own facility in New Brunswick for Ampligen(R).
This installation and consolidation will increase production capacity, improve
efficiency and assure compliance procedures with worldwide drug manufacturing
standards.

            Cost of goods sold for the three months ended September 30, 2004 and
2005 were $109,000 and $93,000, respectively. Since acquiring the right to
manufacture and market Alferon N Injection(R) in March 2003, we have focused on
converting the work-in-progress inventory into finished goods. 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 34,000 vials have been produced. In August
2004, we released most of the second lot of product to Hospira (formerly Abbott
Laboratories) for bottling and realized approximately 12,000 vials of Alferon N
Injection(R). 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). Hospira is in the process of completing
the labeling and packaging of these approximately 12,000 vials of Alferon N
Injection(R) work-in-progress inventory and we anticipate that these vials will
be released into finished goods inventory by mid-November 2005. 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 five new
potential contract manufacturers to replace Hospira, obtained proposals from all
five, and have audited two concerning the future formulation and packaging of
Alferon N Injection(R). We are in the process of reviewing these proposals. If
we are unable to secure a new facility within a reasonable period of time to
formulate and package Alferon N Injection(R) at an acceptable cost, our ability
to sell Alferon N Injection(R) and to generate profits therefrom will be
adversely affected.

            We plan on initiating the process of converting the third lot of
approximately 13,000 vials of Alferon N Injection(R) from work-in-progress to
finished goods inventory in the first half of 2006. We elected to delay the
process of converting this third lot as a result of two factors: 1) we are
concentrating on the relevant manufacturing operations within our New Brunswick,
New Jersey facility for the production of Ampligen(R) raw materials and 2)
Alferon N Injection(R) inventory on hand is sufficient to meet current demand.
Approximately 2,000 vials were abstracted from the third lot for research and
development purposes during the fourth quarter 2004. 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.

            The installation of an Ampligen(R) raw material production line
within our New Brunswick facility should be completed by year end 2005. The
transfer of Ampligen(R) raw materials manufacture 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 43,000 sq. ft. wholly owned
facility are FDA approved for Alferon N Injection(R) manufacture). This will
also allow us to obtain Ampligen(R) raw materials on a more consistent
manufacturing basis. In May 2005, we committed to purchase equipment related to
the manufacture of Ampligen(R) raw material in the amount of approximately
$628,000. We estimate the total cost of establishing this production line to be
some $1,800,000, including modifications to our New Brunswick facility.


                                       54


Research and Development costs

            Overall research and development direct costs for the three months
ended September 30, 2004 and 2005 were $974,000 and $987,000, 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
and cancers as well as on-going clinical trials involving patients with HIV. In
addition, these costs reflect direct costs incurred relating to the development
of Alferon LDO (low dose oral interferon alfa-N3, human leukocyte derived). We
have over approximately 150,000 doses on hand of Alferon 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
are in the process of visiting the multiple clinical study sites around the
country and are collecting and auditing data generated at each of these sites.
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.

            We believe that our recently completed 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 recent 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 40,000
administrations of the studied drug to approximately 700 ME/CFS patients.

            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


                                       55


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.
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.

             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 application ("NDA"). Given these
variables, we are unable to project when material net cash inflows are expected
to commence from the sale of Ampligen(R).

            Ampligen(R) is currently 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 ramping up the AMP 720 study.

            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. We enrolled two new patients in
this study in the third quarter. 41 HIV patients have already participated in
this 64 week study. It is difficult to estimate the duration or projected costs
of this clinical trial 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


                                       56


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 $2.5 to $3.0 million if the
target of 120 patients is achieved. 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 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.

            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.

            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. 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 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 avain
influenza. The preclinical study suggests a new, and potentially pivotal role of
double-stranded RNA ("dsRNA") therapeutics in improving the efficiacy 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
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). Further immediate experimental tests are planned.


                                       57


            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 Hemispherx' experimental therapeutic
Ampligen(R) as an adjuvant 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 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.

            A clinical study to evaluate the use of Alferon 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 LDO can resuscitate
the broad-spectrum antiviral and immunostimulatory genes. The initial patient
enrolled in this study in July 2005 and, as of October 2005, five patients have
completed dosing. 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 World Health
Organization (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 October
2005, nine patients have entered this study. The CDC reports that 1,804 cases of
West Nile Virus have been reported in the US as of September 27, 2005, including
52 deaths.

            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-Plough ("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 September 9, 2005, we signed a Letter of Intent ("LOI") with
Hollister-Stier Laboratories LLC of Spokane, Washington ("Hollister-Stier"), for
the contract manufacturing of Ampligen(R). In November 2005, we paid $100,000
upon executing the LOI in order to initiate the manufacturing project. The LOI
shall remain in full force and effect for 90 calendar days or until a definitive
agreement is reached. The achievement of the initial objectives described in the
LOI, 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. Based on the LOI,
Hollister-Stier has agreed to formulate and bottle Ampligen(R) using raw
materials received from us. We have an executed confidentiality agreement in
place and; therefore, have commenced the preliminary transfer of our
manufacturing technology to Hollister-Stier. Our decision to transfer relevant
manufacturing technology absent of an executed agreement, was done in part to
expedite the eventual manufacture of Ampligen(R) by Hollister-Stier. If we are
unable to negotiate and finalize an agreement with Hollister-Stier, in a timely
manner our plans to file an NDA for Ampligen(R) and, eventually, to market and
sell Ampligen(R) will be delayed.

            We have identified two other capable cGMP facilities in the US for
the manufacture of Ampligen(R) and obtained proposals from both. If either of
these two facilities are acceptable, we would be able to maintain a minimum of
two independent production sites. We are in the process of reviewing these other
proposals.

General and Administrative Expenses

            General and Administrative ("G&A") expenses for the three months
ended September 30, 2004 and 2005 were approximately $1,299,000 and $1,384,000,
respectively. The increase in G&A expenses of $85,000 during this period is
primarily due to stock compensation of $53,000 and higher public accounting and
other professional fees.

Interest and Other Income

            Interest and other income for the three months ended September 30,
2004 and 2005 totaled $32,000 and $250,000, respectively. The increase in
interest and other income during the current quarter 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

            Interest and Expense non-cash financing costs were approximately
$700,000 for the three months ended September 30, 2005 versus $1,097,000 in
charges for the same three months a year ago. Non-cash financing costs consist
of the amortization of Original Issue Discounts and the amortization of 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 of
$397,000 can be attributed to the aggregate total of these charges being reduced
since 2004 due to decreased amortization charges as well as charges related to
the conversion of debentures. Please see Note 8 in the consolidated financial
statements contained herein for more details on these transactions.

Deemed Dividend

            Deemed dividend for the three months ended Septemeber 30, 2004 and
2005, was $1,676,000 and $0, respectively. This represents the fair value of the
warrants issued to our debenture holders as incentive to exercise prior warrant
issuances.

            Nine months ended September 30, 2004 versus Nine months ended
September 30, 2005

Net Loss Applicable to Common Stockholders

            Our net loss applicable to common stockholders of $8,968,000 for the
nine months ended September 30, 2005 was down $9,063,000 or 50% compared to the
same period in 2004. This reduction was primarily due to: 1) lower costs
associated with non-cash financing charges related to convertible debentures.
These lower non-cash financing costs of $1,999,000 represented 22% of the change
in net loss from period to period, 2) production/costs of good sold expenditures
were down $1,697,000 due to expenditures during the first three quarters of 2004
associated with ramping up of the New Brunswick facility for further production
of Alferon N Injection(R), 3) lower non-cash stock compensation expenses of
approximately $2,000,000 and 4) deemed dividend of $4,031,000 recorded upon the
issuance of warrants to our debenture holders as incentive to exercise prior
warrant issuances during the second and third quarters 2004. Net loss applicable
to common stockholders was $(.18) per share for the current period versus $(.41)
per share for the same period 2004.

Revenues

            Revenues for the nine months ended September 30, 2005 were $829,000
as compared to revenues of $907,000 for the same period in 2004. Ampligen(R)
sold under the cost recovery clinical program was up $16,000 (13%) and Alferon N
Injection sales were down $94,000 (12%). For more information concerning
revenue, see the revenue section contained in the results of operations for the
three months ended September 30, 2004 versus three months ended September 30,
2005 discussed above.

Production costs/cost of goods sold

            Production costs for the nine months ended September 30, 2004 were
$1,641,000. These costs represented expenditures associated with preparing the
New Brunswick facility for further production of Alferon N Injection(R) in the
first three quarters of 2004. There were no production costs for Alferon N
Injection(R) during the first nine months of 2005 as we concentrated on the
completion of the consolidation of all raw material manufacturing and research
and development activities within our facility in New Brunswick for Ampligen(R).
This consolidation will improve production capacity, efficiency, and compliance
procedures and bring the facility in line with worldwide drug manufacturing
standards.

            Cost of goods sold for the nine months ended September 30, 2004 and
2005 were $350,000 and $294,000, respectively. For more information concerning
production/cost of goods sold, see the production/costs of goods sold section
contained in the results of operations for the three months ended September 30,
2004 versus three months ended September 30, 2005 discussed above.

Research and Development costs

            Overall research and development direct costs for the nine months
ended September 30, 2004 and 2005 were $2,696,000 and $3,413,000, respectively.
For more information on research and development activities, see the research
and development section contained within the results of operations for the three
months ended September 30, 2004 versus three months ended September 30, 2005
discussed above.


                                       60


General and Administrative Expenses

            General and Administrative ("G&A") expenses for the nine months
ended September 30, 2004 and 2005 were approximately $5,229,000 and $3,933,000,
respectively. The decrease in G&A expenses of $1,296,000 during this period is
primarily due to a non-cash stock compensation charge 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. The warrants
vested upon the second ISI asset closing which occurred on March 17, 2004.
Higher professional fees, specifically legal costs, during the first nine months
of 2005, slightly offset this decrease in G & A expenses, from period to period.
The costs were associated with lawsuits we initiated seeking injunctive relief
and damages against conspiratorial groups alleging that the conspiratorial group
engaged in illegal activities to take over Hemispherx and enrich themselves at
the expense of our shareholders. Please see Item 1. "Legal Proceedings" in Part
II - Other Information, below for more information.

Interest and Other Income

            Interest and other income for the nine months ended September 30,
2004 and 2005 totaled $56,000 and $543,000, respectively. The increase in
interest and other income during the current quarter can primarily be attributed
to the maturing of marketable securities during the 2005 period.

Interest Expense and Financing Costs

            Interest expense and non-cash financing costs were approximately
$2,700,000 for the nine months ended September 30, 2005 versus $4,674,000 for
the same nine months a year ago. Non-cash financing costs consist of the
amortization of Original Issue Discounts and the amortization of costs
associated with beneficial conversion features of our debentures and the
relavtive 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 of
$1,974,000 can be attributed to the aggregate total of these charges being
reduced since 2004 due to a decrease in amortization charges and additional
financing costs during the first half of 2004 with regard to our January 2004
debenture and the impact of Section 713 of the American Stock Exchange Company
Guide. Please see Note 8 "Section 713 of The American Stock Exchange Company
Guide" in the consolidated financial statements contained herein for more
details on these transactions and for details on our debenture and stock
financings.

Deemed Dividend

            Deemed dividend for the nine months ended September 30, 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.

Liquidity and Capital Resources

            Cash used in operating activities for the nine months ended
September 30, 2005 was $5,283,000. As of September 30, 2005, we had
approximately $11,632,000 million in cash and short-term investments. These
funds should be sufficient to meet our operating cash requirements including
debt service for the near term. For detailed information on our debenture and
equity financings during this period, please see Note 8 and 9 in the
consolidated financial statements contained herein.

            In May 2005, we committed to purchase lab equipment related to the
manufacture of Ampligen(R) raw material ("polymers") in the amount of
approximately $628,000. The overall cost of establishing the polymer production
line at the New Brunswick facility is estimated at $1,800,000.

            As of November 1, 2005, we have made aggregate installment payments
of $2,389,000 and the investors have converted an aggregate $2,762,000 principal
amount of debt from the Debentures noted below (in thousands):

            On July 8, 2005, we 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 our common stock up to an aggregate of $20.0 million over
approximately a 25 month period, subject to earlier termination at our
discretion. For detailed information on our equity financing, please see Note 9
in the consolidated financial statements contained here in.

            Pursuant to our agreement with Fusion Capital, we have registered
for public sale by Fusion Capital up to 10,795,597 shares of our common stock.
However, in the event that we decide 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, we would first seek stockholder approval in order to be in compliance
with American Stock Exchange rules.

            This funding arrangement with Fusion Capital plus our current cash
position should be sufficient to meet our operating cash requirements for the
next 30 months. However, we may need to raise additional funds through equity or
debt financing or from other sources to the extent that we do not receive
adequate funding from Fusion Capital (see "Risk Factors - We may require
additional financing that may not be available") and to complete the regulatory
processes including the commercialization of Ampligen(R) products. There can be
no assurances that we will raise funds from these or other sources, which may
have a material adverse effect on our ability to develop our products.

            Effective October 6, 2005, the Company entered into a material
definitive agreement with the debenture holders to 1) amend the remaining
outstanding debentures that were to mature on October 31, 2005 (as amended, the
"Series A Debenture") and the two traunches of outstanding debentures due to
mature on January 31, 2006 (as amended, respectively, the "Series B and Series C
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.

            Also, because of our long-term capital requirements, we may seek to
access the public equity market whenever conditions are favorable, even if we do
not have an immediate need for additional capital at that time. 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 processes, including the commercializing of Ampligen products.


                                       62


            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. Also, we have the ability to curtail discretionary
spending, including some research and development activities, if required to
conserve cash.

Item 4: Controls and Procedures

Evaluation of Disclosure Controls and Procedures

            An evaluation of the effectiveness of the design and operation of
our disclosure controls and procedures (as defined in Rule 13a-15(e) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end
of the period covered by this Quarterly Report on Form 10-QA was made under the
supervision and with the participation of management, including our Chief
Executive Officer and Chief Fincancial Officer. In connection with such
evaluation, our Chief Executive Officer and Chief Financial Officer have
concluded that our disclosure controls and procedures were not effective based
on the material weaknesses in internal control over financial reporting
described in our Annual Report on Form 10-K/A for the period ended December 31,
2005.

Remediation of Material Weaknesses

            During the second quarter of 2006, to remedy the material weakness
in our internal control over financial reporting, we initiated the process of
establishing procedures to enhance controls over the "financial statement close
and disclosure" process which included subscribing to CCH's "Accounting Research
Manager", a recognized on-line service in order to maintain up-to-date
accounting and disclosure guidance. In addition, we have established policies
and procedures to include a detailed comprehensive review of the underlying
information supporting the amounts included within our consolidated financial
statements and disclosures including documented reviews to assist in ensuring:
1) clerical accuracy within our financial statements and disclosures, 2)
financial statement groupings within our financial statements are accurate, 3)
support utilized in preparation of the consolidated statement of cash flows is
accurate, and 4) equity transactions during the reporting period are completely
and accurately recorded. We engaged an additional accounting consultant in April
2006 to assist in initiating the implementation of these policies and procedures
during the second quarter 2006. The control deficiencies will be fully
remediated when in the opinion of the Company's management, the revised control
processes have been operating for a sufficient period of time to provide
reasonable assurance as to their effectiveness. The Company believes it will be
able to make this assessment by December 31, 2006.

Changes in Internal Controls

            Other than as described above, there was no change in our internal
controls over financial reporting (as defined in Rule 13a-15(f) of the Exchange
Act) that occurred during the period covered by this report that has materially
affected, or is reasonably likely to materially affect, our internal controls
over financial reporting.
