                                   WHO WE ARE

      Our  company  was  formed in May 2000  under  Delaware  law solely for the
purposes of combining two companies,  STC Technologies,  Inc. and Epitope, Inc.,
and changing the state of incorporation of Epitope from Oregon to Delaware.  STC
Technologies and Epitope were merged into our company on September 29, 2000. Our
principal  offices are located at 150 Webster  Street,  Bethlehem,  Pennsylvania
18015, and our telephone number is (610) 882 -1820.

      We develop,  manufacture and market oral fluid specimen collection devices
using our proprietary oral fluid technologies,  proprietary  diagnostic products
including in vitro diagnostic  tests, and other medical devices.  These products
are sold in the United  States  and  certain  foreign  countries  to  government
agencies,  clinical  laboratories,  physician  offices,  and hospitals,  and for
workplace testing.

      Our business focuses on the following principal platform technologies: (1)
the  OraSure(R)  oral  fluid  collection   device,  (2)  the  OraQuick(R)  rapid
diagnostics test device, and (3) the new up-converting  phosphor technology,  or
UPT(TM), including its first application, UPlink(TM).

      The  OraSure(R)  collection  device  is used to  collect  a sample of oral
fluid,  or  saliva,  which  is  then  sent to a  laboratory  for  screening  and
confirmatory tests for HIV-1 (the virus that causes AIDS) and/or for cocaine and
cotinine (an indicator of the use of nicotine).  The  OraSure(R)  device is sold
predominantly  in the  insurance  market  for the  screening  of life  insurance
applicants  and in  physician  offices  and  in  the  public  health  market.  A
collection  device that is  substantially  similar to the  OraSure(R)  device is
marketed  under the name  Intercept(R)  and is used to collect  oral fluid to be
tested in a laboratory for various drugs, such as marijuana,  cocaine,  opiates,
amphetamines, PCP, benzodiapines,  barbiturates, and methadone.  Intercept(R) is
used primarily by companies to test their employees and  prospective  employees,
in crime and medical examiner  laboratories for forensic  toxicology testing, in
the criminal justice system for testing prison inmates and parolees, and in drug
treatment and community/family service programs.

      The OraQuick(R)  device is a recently  developed  product designed to test
oral fluid,  whole blood or serum/plasma  for the presence of HIV. No laboratory
test is  required,  as the  OraQuick(R)  test  results can be  visually  read in
approximately  20 minutes after the sample is  collected.  We plan to market the
OraQuick(R) device in the hospital,  physician office and public health markets,
focusing initially on international markets.


      Up-converting phosphor technology,  or UPT(TM), uses phosphor particles to
detect the  presence of small  quantities  of a variety of  substances,  such as
drugs,  proteins and DNA. The first application of UPT(TM) is called UPlink(TM),
a system  which  collects,  analyzes  and  measures  substances  in a variety of
samples,  including  oral fluid,  blood,  serum,  urine and stool  samples,  and
provides results in about 10 minutes without laboratory testing.  The UPlink(TM)
system  provides  a high  degree  of  sensitivity  and  can  test  for  multiple
substances  at the same time. We are nearing  completion  of an UPlink(TM)  oral
fluid test for various drugs and are developing UPlink(TM)  applications to test
for various infectious diseases.


      In addition, we sell certain other products, including the Histofreezer(R)
cryosurgical  system for the  removal of warts and other skin  lesions,  certain
tests and related products for insurance risk assessment and forensic toxicology
applications,  an oral fluid Western Blot  confirmatory  test for HIV-1, and the
Q.E.D.(R) saliva alcohol test.


                                  RISK FACTORS

      You should  carefully  consider the risks described below before making an
investment  decision.  They  are  the  material  risks  currently  known  to us.
Additional  risks not presently known to us or that we currently deem immaterial
may also impair our business operations.

      Our  business,  financial  condition  or  results of  operations  could be
materially  adversely  affected by any of these risks.  The trading price of our
common stock could  decline due to any of these  risks,  and you may lose all or
part of your investment.

                                       1



      This  prospectus  also contains  forward-looking  statements  that involve
risks and  uncertainties.  Our actual results could differ materially from those
anticipated in these forward-looking  statements as a result of certain factors,
including  the  risks  faced  by  us  described  below  and  elsewhere  in  this
prospectus.

WE FACE INTENSE COMPETITION FROM NEW AND EXISTING DIAGNOSTIC PRODUCTS.

      The diagnostic industry is focused on the testing of biological  specimens
in a laboratory  or at the point of care and is highly  competitive  and rapidly
changing.   Our  principal  competitors  have  considerably  greater  financial,
technical,  and  marketing  resources.  As new  products  enter the market,  our
products may become obsolete or a competitor's products may be more effective or
more effectively marketed and sold than ours. If we fail to maintain and enhance
our competitive position,  our customers may decide to use products developed by
competitors which could result in a loss of revenues.

OUR RESEARCH AND DEVELOPMENT EFFORTS MAY NOT SUCCEED OR OUR COMPETITORS MAY
DEVELOP MORE EFFECTIVE OR SUCCESSFUL DIAGNOSTIC PRODUCTS.

      In order to remain competitive,  we must commit substantial resources each
year to research and development. The research and development process generally
takes a significant  amount of time from inception to commercial product launch.
This process is conducted  in various  stages,  and during each stage there is a
substantial  risk that we will not  achieve our goals and will have to abandon a
product in which we have invested substantial amounts.

      During  the  year  ended  December  31,  2000 and the  nine  months  ended
September  30, 2001, we incurred  approximately  $10.4 million and $6.8 million,
respectively,  in research and  development  expenses.  We expect to continue to
incur  significant costs in our research and development  activities.  Moreover,
there can be no assurance  that we will succeed in our research and  development
efforts.  If  we  fail  to  develop  commercially  successful  products,  or  if
competitors  develop more  effective  products or a greater number of successful
new products, customers may decide to use products developed by our competitors,
which would result in a loss of revenues.

IF ACCEPTANCE AND ADOPTION OF OUR ORAL FLUID TESTING IN THE MARKET DOES NOT
CONTINUE, OUR FUTURE RESULTS MAY SUFFER.

      We have made  significant  progress in gaining  acceptance and adoption of
oral fluid testing for HIV in the insurance and public health  markets.  We also
expect that oral fluid  testing for drugs of abuse will  continue to be accepted
and adopted in workplace and criminal  justice testing  markets.  Other markets,
particularly the physician market, may resist the adoption of oral fluid testing
as a  replacement  for  other  testing  methods  in use  today.  There can be no
assurance  that we will be able to  expand  the use of our  oral  fluid  testing
products in these or other markets.

WE MAY REQUIRE FUTURE ADDITIONAL FUNDING TO STAY IN BUSINESS.

      Although we have made significant  progress in the past toward controlling
expenses and increasing  product revenue,  we have historically  depended,  to a
substantial  degree, on capital raised through the sale of our equity securities
to fund our  operations.  Our future  liquidity  and capital  requirements  will
depend on numerous factors,  including, but not limited to, the costs and timing
of the  expansion  of our  manufacturing  capacity,  the  success of our product
development  efforts,  the  costs  and  timing  of  expansion  of our  sales and
marketing activities,  the extent to which existing and new products gain market
acceptance,  competing technological and market developments,  and the scope and
timing of strategic acquisitions. If additional financing is needed, we may seek
to raise  funds  through  the sale of our  equity  securities.  There  can be no
assurance  that  financing  through  the  sale  of  our  equity  securities,  or
otherwise, will be available on satisfactory terms, if at all.

OUR FAILURE TO MAINTAIN EXISTING DISTRIBUTION CHANNELS OR DEVELOP NEW
DISTRIBUTION CHANNELS, MAY RESULT IN LOWER REVENUES.

                                       2



      We have marketed  many of our products by  collaborating  with  diagnostic
companies and  distributors.  For example,  our OraSure(R) oral fluid collection
device is distributed to the insurance  industry through major insurance testing
laboratories. One of these laboratories, LabOne,Inc., is a significant customer,
accounting  for  approximately  23% and 21.8% of our revenues for the year ended
December 31, 2000 and the nine months ended  September  30, 2001,  respectively.
Our sales  depend to a  substantial  degree on our  ability to sell  products to
these  customers  and  develop  new  product  distribution  channels  and on the
marketing  abilities of the companies  with which we  collaborate.  In addition,
some of our distributors have recently consolidated, and such consolidation has,
and many  continue  to have,  an  adverse  impact  on the level  orders  for our
products. There can be no assurance that such companies will continue to be able
to purchase or distribute  our products or maintain  order  volume,  or that new
distribution channels will be available on satisfactory terms.


THE TIME NEEDED TO OBTAIN REGULATORY APPROVALS AND RESPOND TO CHANGES IN
REGULATORY REQUIREMENTS COULD ADVERSELY AFFECT OUR BUSINESS.

      Many of our proposed and existing  products are subject to  regulation  by
the United States Food and Drug  Administration  ("FDA") and other international
governmental  agencies.  In  particular,  we are subject to strict  governmental
controls on the development,  manufacture,  labeling, distribution and marketing
of our products.  The process of obtaining  required  approvals from  government
agencies varies  according to the nature of, and uses for, our specific  product
and can involve lengthy and detailed laboratory testing,  human clinical trials,
sampling activities, and other costly, time-consuming procedures. The submission
of an  application  to a regulatory  authority  does not guarantee  that it will
grant us a license  to market the  product.  Each  authority  may impose its own
requirements and delay or refuse to grant approval,  even though our product has
been approved in another country.

      In our principal  markets,  the approval  process for a new product can be
complex and lengthy.  The time taken to obtain approval varies  depending on the
nature of the application and may result in the passage of a significant  period
of time from the date of submission of the application. This time span increases
our  costs to  develop  new  products  and  increases  the risk that we will not
succeed in introducing or selling them.

      Changes  in  government  regulations  could  also  require  us to  undergo
additional trials or procedures,  or could make it impractical or impossible for
us to market our products for certain uses, in certain markets, or at all. Other
changes in  government  regulations,  such as the adoption of the FDA's  Quality
System  Regulation,  may not affect our products directly but may,  nonetheless,
adversely affect our financial  condition and results of operations by requiring
that we incur the expense of  changing or  implementing  new  manufacturing  and
control procedures.

      In  addition,  the  European  Union has  established  a  requirement  that
diagnostic  medical  devices  used to test  biological  specimens  must  receive
regulatory approval known as a CE mark by December 2003. After that date, export
to the  European  community  of products  without the CE mark will be stopped or
delayed  until the mark is received.  This  requirement  will affect many of our
products.  We will not be permitted  to sell our products in European  countries
without a CE mark after  December 2003,  which could lead to the  termination of
strategic  alliances for sales of those  products in Europe.  While we intend to
apply for CE marks for certain of our existing and future products,  and are not
aware of any material  reason why such approvals will not be granted,  there can
be no assurance that any CE marks will be received prior to the deadline.

      At the present  time,  we have  received FDA clearance or approval for the
OraSure(R) and Intercept(R) oral fluid collection  devices,  the Histofreezer(R)
portable cryosurgical system, the Q.E.D. (R) saliva alcohol test, the OraSure(R)
oral fluid Western Blot  confirmatory test for HIV-1 and various other tests. We
have  also  received  CE mark  approval  for the  OraSure(R),  Intercept(R)  and
Histofreezer(R)  products.  We  have  submitted  to the FDA an  application  for
pre-market  approval  of our  OraQuick(R)  rapid HIV test using  whole blood and
expect to file an application  for oral fluid  applications  early next year. We
have also  submitted an  application to the FDA for clearance of the UPlink (TM)
drugs of abuse rapid  detection  system and are presently  gathering  additional
data requested by the FDA in response to our application.

WE HAVE A HISTORY OF LOSSES.


      We have not achieved  full-year  profitability.  We incurred a net loss of
approximately  $12.7  million and $4.2 million for the years ended  December 31,
2000 and September 30, 1999, respectively,  and a net loss of

                                       3



approximately  $1.4 million for the nine months ended  September 30, 2001. As of
September  30,  2001,  we had an  accumulated  deficit of  approximately  $123.8
million.  On January 18, 2002, we announced  preliminary  results for the fourth
quarter and full-year  2001,  which  indicate that we expect to incur a net loss
for both the quarter and full year.


      Our limited combined  operating history makes it difficult to forecast our
future operating results.  In order to achieve  sustainable  profitability,  our
revenue  will have to continue  to grow at a  significant  rate.  Our ability to
reach our estimated  revenue  growth will be dependent  upon a number of factors
including, without limitation, achieving growth in international markets through
our OraQuick(R)  rapid HIV test, our ability to create market acceptance for the
Intercept(R)  drugs of abuse products and our ability to  commercially  develop,
and obtain  regulatory  approval and create market  acceptance for,  UPT(TM) and
other products in a time frame  consistent with our objectives.  We have not yet
achieved  these  objectives.  In the event that we cannot  create a  significant
commercial  market  for our  OraQuick(R)  test,  the  Intercept(R)  and  UPT(TM)
products or our other products,  our revenue,  and  consequently  profitability,
will be lower than estimated. Even if we achieve profitability, we cannot assure
you that we will be able to sustain such profitability in the future.

FAILURE TO COMPLY WITH FDA REQUIREMENTS MAY REQUIRE US TO SUSPEND PRODUCTION OF
OUR PRODUCTS WHICH COULD RESULT IN A LOSS OF REVENUES.

      We can manufacture and sell many of our products,  both in the U.S. and in
some cases abroad,  only if we comply with regulations of governmental  agencies
such as the FDA. We have  implemented  quality  assurance and other systems that
are  intended to comply  with such  applicable  regulations.  The FDA has issued
warning letters and a letter of intent to revoke our license with respect to the
serum Western Blot product, stating that we are not in compliance with the FDA's
regulations.  We have  responded to each of these  letters.  Although we believe
that we are  addressing all of the points raised by the FDA, the FDA could force
us to stop manufacturing  products if the FDA concludes that we still remain out
of compliance  with  applicable  regulations.  Until the FDA agrees that we have
resolved all of the points raised in their letters, we may not be able to obtain
regulatory clearance  certificates needed in certain foreign countries.  The FDA
could also  require us to recall  products if we fail to comply with  applicable
regulations which could force us to stop manufacturing such products.

A MARKET FOR OUR PRODUCTS MAY NOT DEVELOP.

      Our future success will depend, in part, on the market acceptance, and the
timing of such  acceptance,  of our  recently  introduced  products  such as the
Intercept(R) oral fluid drug test service,  the OraQuick(R) rapid oral fluid HIV
test, products currently under development such as UPlink(TM) and other products
using up-converting phosphor technology,  and other new products or technologies
that may be  developed  or acquired  and  introduced  in the future.  To achieve
market  acceptance,  we  must  make  substantial  marketing  efforts  and  spend
significant  funds to inform potential  customers and the public of the benefits
of these products.  We currently have limited  evidence on which to evaluate the
market reaction to products that may be developed, and there can be no assurance
that any products will meet with market acceptance and fill the market need that
is perceived to exist.

OUR SUCCESS DEPENDS ON OUR ABILITY TO PROTECT OUR PROPRIETARY TECHNOLOGY.

      The  diagnostics  industry  places  considerable  importance  on obtaining
patent,  trademark,  and trade secret protection,  as well as other intellectual
property  rights,  for new  technologies,  products and  processes.  Our success
depends,  in part, on our ability to develop and maintain a strong  intellectual
property portfolio of products and technologies both in the United States and in
other countries.

      As appropriate,  we intend to file patent  applications  and obtain patent
protection for our proprietary technology. These patent applications and patents
will cover, as appropriate,  compositions of matter for our products, methods of
making those products,  methods of using those products,  and apparatus relating
to the use or manufacture of those products. We will also rely on trade secrets,
know-how and continuing  technological  advancements  to protect our proprietary
technology.  We have  entered and will  continue  to enter into  confidentiality
agreements with our employees, consultants, advisors and collaborators. However,
these  parties  may  not  honor  these  agreements  and we may  not be  able  to
successfully protect our rights to unpatented trade secrets and know-how. Others
may independently develop substantially  equivalent proprietary  information and
techniques or otherwise gain access to our trade secrets and know-how.

                                       4



      Many of our employees, including scientific and management personnel, were
previously employed by competing companies. Although we encourage and expect all
of  our  employees  to  abide  by any  confidentiality  agreement  with a  prior
employer,  competing  companies may allege trade secret  violations  and similar
claims against us.

      To  facilitate   development  and   commercialization   of  a  proprietary
technology base, we may need to obtain licenses to patents or other  proprietary
rights from other  parties.  If we are unable to obtain these types of licenses,
our product development and commercialization efforts may be delayed.

      We  may  collaborate   with   universities   and   governmental   research
organizations  which,  as a  result,  may  acquire  part  of the  rights  to any
inventions or technical information derived from collaboration with them.

      We may incur substantial costs in asserting or protecting our intellectual
property  rights,  or in  defending  suits  against us  related to  intellectual
property  rights.   Disputes  regarding   intellectual   property  rights  could
substantially  delay  product  development  or   commercialization   activities.
Disputes regarding  intellectual  property rights might include state or federal
court litigation as well as patent interference,  patent  reexamination,  patent
reissue,  or trademark  opposition  proceedings  in the United States Patent and
Trademark Office.  Opposition or revocation proceedings could be instituted in a
foreign  patent  office.  An  adverse  decision  in  any  proceeding   regarding
intellectual property rights could result in the loss of our rights to a patent,
an invention, or trademark.

THE SALES POTENTIAL FOR ORAQUICK WILL BE AFFECTED BY OUR ABILITY TO OBTAIN
CERTAIN LICENSES.

      There are several factors that will affect the specific countries in which
we will be able to sell our OraQuick(R) rapid HIV test and therefore the overall
sales  potential of the test.  One factor is whether we can arrange a sublicense
or distribution  agreement  related to patents for detection of the HIV-2 virus.
HIV-2 is a type of the HIV virus  estimated to  represent  less than 2% of known
HIV  cases  worldwide.  Nevertheless,  HIV-2 is  considered  to be an  important
component in the testing  regimen for HIV in many markets.  HIV-2 patents are in
force in most of the countries of North America and Western  Europe,  as well as
in Japan, Korea, South Africa and Australia. Access to a license for one or more
HIV-2  patents  may be  necessary  to sell HIV-2 tests in  countries  where such
patents are in force,  or to manufacture in countries  where such patents are in
force and then sell into non-patent markets. Since HIV-2 patents are in force in
the U.S., we may be restricted from manufacturing our OraQuick(R) rapid HIV test
in the U.S.  and  selling  into  other  countries,  even if there  were no HIV-2
patents in those other countries.

      The  importance of HIV-2  differs by country,  and can be affected by both
regulatory  requirements and by competitive  pressures.  In most countries,  any
product  used to screen the blood  supply  will  require  the  ability to detect
HIV-2,  although the  OraQuick(R)  rapid HIV test has not been intended for that
market  purpose.  In other  markets,  including the U.S., a test that can detect
only the more prevalent HIV-1 type is generally considered sufficient, except in
testing  related to blood  supply.  Because the  competitive  situation  in each
country will be affected by the  availability of other testing  products as well
as the country's regulatory environment, we may be at a competitive disadvantage
in some markets without an HIV-2 product even if HIV-2 detection is not required
by regulations.

      Another factor that may affect the specific  countries in which we will be
able to sell our  OraQuick(R)  rapid HIV test,  and  therefore the overall sales
potential,  concerns  whether  we  can  arrange  a  sublicense  or  distribution
agreement  related to any patents  which claim  lateral  flow assay  methods and
devices  covering the  OraQuick(R)  rapid HIV test or its use.  The  OraQuick(R)
rapid HIV test is a lateral flow assay device that tests for specific antibodies
or other  substances.  The term "lateral flow" generally  refers to a test strip
through  which a sample  flows and which  produces  a visible  test  result on a
portion of the strip  downstream  from where the  sample is  applied.  There are
numerous  patents in the U.S. and other countries which claim lateral flow assay
methods and devices.  Some of these patents broadly cover the type of technology
used in the OraQuick(R)  assay and are in force in the U.S and other  countries.
We may not be able to make the  OraQuick(R)  rapid HIV test in the U.S. and sell
it in countries  where there is no patent on the device.  We have licenses under
several  lateral flow patents and are  considering  the need for licenses  under
others.

                                       5



      In the event  that it is not  possible  to  negotiate  a license  or other
agreement  under a necessary  patent,  we may be able to modify the  OraQuick(R)
rapid  HIV test  such  that a license  would  not be  necessary.  However,  this
alternative could delay  introduction of the OraQuick(R) rapid HIV test into the
U.S. and other markets.

IF WE LOSE OUR KEY PERSONNEL OR ARE UNABLE TO ATTRACT AND RETAIN QUALIFIED
PERSONNEL AS NECESSARY, OUR BUSINESS COULD BE HARMED.

      Our success  will depend to a large extent upon the  contributions  of our
executive officers,  management,  sales and marketing,  and scientific staff. We
may not be able to attract or retain  qualified  employees  in the future due to
the  intense   competition  for  qualified   personnel  among  medical  products
businesses.  If we are not able to attract and retain the necessary personnel to
accomplish  our business  objectives,  we may experience  constraints  that will
adversely  affect our ability to  effectively  sell and market our products,  to
meet the demands of our  strategic  partners  in a timely  fashion or to support
internal research and development programs.  In particular,  product development
programs depend on the ability to attract and retain highly skilled  scientists,
including molecular biologists,  biochemists and engineers. Recruiting qualified
personnel can be an intensely competitive and time-consuming  process.  Although
we  believe  we  will  be  successful  in  attracting  and  retaining  qualified
personnel,  competition  for  experienced  scientists  and other  personnel from
numerous  companies and academic and other research  institutions  may limit our
ability to do so on acceptable  terms.  All of our  employees,  other than a few
senior officers who have employment  agreements,  are at-will  employees,  which
means that either the employee or we may terminate their employment at any time.
If we experience difficulty in recruiting and retaining qualified personnel, and
in particular scientific  personnel,  we may need to provide higher compensation
to such personnel than currently anticipated or we may incur additional expenses
for the recruitment of qualified personnel.

      Our  business  plans  will  require   additional   expertise  in  specific
industries  and  areas   applicable  to  the  development   efforts  related  to
up-converting phosphor technologies.  These activities will require the addition
of new  personnel,  including  management,  and the  development  of  additional
expertise by existing  management  personnel.  The  inability  to acquire  these
services or to develop this expertise could impair the  development,  if any, of
products related to this technology.

OUR INCREASING INTERNATIONAL PRESENCE MAY BE AFFECTED BY REGULATORY, CULTURAL OR
OTHER RESTRAINTS.

      We intend to devote significant resources to increase  international sales
of our OraSure(R), Intercept(R), OraQuick(R) and UPT(TM) products. The Company's
international  operations accounted for approximately $4 million or 14% of total
revenues for the year ended December 31, 2000 and approximately  $3.9 million or
15.9% of total revenues for the nine months ended September 30, 2001.

      Compliance with foreign  regulatory  requirements can be difficult and can
impede international marketing efforts. In the past, we have not had significant
direct experience with the governmental regulatory agencies in foreign countries
that control sale of products into those countries.  In addition to economic and
political issues, a number of factors can slow or prevent  international  sales,
or substantially  increase the cost of international sales,  including those set
forth below:

o     Regulatory  requirements  (including  compliance with  applicable  customs
      regulations)  may slow,  limit,  or prevent  the  offering  of products in
      foreign jurisdictions;

o     Cultural and political  differences  may make it difficult to  effectively
      market, sell and gain acceptance of products in foreign jurisdictions;

o     Inexperience  in  international  markets  may slow or limit our ability to
      sell products in foreign countries;

o     Exchange  rates,  currency  fluctuations,   tariffs  and  other  barriers,
      extended  payment  terms and  dependence on and  difficulties  in managing
      international distributors or representatives may affect our revenues even
      when product sales occur; and

                                       6



o     The credit-worthiness of foreign entities may be less certain and accounts
      receivable collection may be more difficult.

      We have  entered  into a contract  for the  manufacture  and supply of the
OraQuick(R) HIV device in Thailand.  However,  we do not have significant direct
experience with the use of international manufacturers. Factors such as economic
and political conditions and foreign regulatory requirements may slow or prevent
the  manufacture  of our  products in  countries  other than the United  States.
Interruption  of the supply of our products could reduce revenues or cause us to
incur significant additional expense in finding an alternative source of supply.

WE MAY BE SUED FOR PRODUCT LIABILITIES FOR INJURIES RESULTING FROM THE USE OF
OUR DIAGNOSTIC PRODUCTS.

      We may be held liable if any of our products, or any product which is made
with the use or incorporation of any of our  technologies,  causes injury of any
type or is found otherwise  unsuitable  during product  testing,  manufacturing,
marketing, sale or usage. Although we have obtained product liability insurance,
this insurance may not fully cover potential  liabilities.  As new products come
to market, we may need to increase our product liability coverage.  Inability to
obtain  sufficient  insurance  coverage at an  acceptable  cost or  otherwise to
protect against  potential product liability claims could affect our decision to
commercialize  products  that we  develop  independently  or with our  strategic
partners.  If we are sued for any injury caused by our  products,  our liability
could exceed our policy limits.

WE MAY NOT BE ABLE TO COMMERCIALIZE OUR UPT(TM) PRODUCTS WHICH COULD NEGATIVELY
AFFECT OUR FUTURE REVENUES.

      Our up-converting  phosphor technology is new and is in the early stage of
development. Commercial development of UPT(TM) may not be successful. Successful
products require significant  development and investment,  including testing, to
demonstrate   their   cost-effectiveness   or  other  benefits  prior  to  their
commercialization. In addition, regulatory approval must be obtained before most
products based upon UPT(TM) may be sold. Additional development efforts on these
products  will be required  before any  regulatory  authority  will review them.
Regulatory  authorities  may not approve  these  products for  commercial  sale.
Accordingly, because of these uncertainties, products based upon UPT(TM) may not
be  commercialized.  The failure to develop  UPT(TM)  products  with  commercial
potential would negatively affect our future revenues.

WE ARE DEPENDENT UPON STRATEGIC PARTNERS TO ASSIST IN DEVELOPING AND
COMMERCIALIZING SOME OF OUR DIAGNOSTIC PRODUCTS.

      Although we intend to pursue  some  product  opportunities  independently,
opportunities   that  require  a  level  of  investment  for   development   and
commercialization  may necessitate  involving one or more strategic partners. In
particular,  our strategy for development and  commercialization  of UPT(TM) and
certain other products may entail  entering into  additional  arrangements  with
corporate partners, universities,  research laboratory licensees, and others. We
may be  required  to  transfer  material  rights  to  such  strategic  partners,
licensees,  and others.  While we expect  that our current and future  partners,
licensees,  and others have and will have an economic  motivation  to succeed in
performing  their  contractual  responsibilities,   the  amount  and  timing  of
resources  to be  devoted  to these  activities  will be  controlled  by others.
Consequently,  there can be no  assurance  that any  revenues or profits will be
derived from such arrangements.

WE ARE DEPENDENT UPON PATENTS, LICENSES AND OTHER PROPRIETARY RIGHTS FROM THIRD
PARTIES, INCLUDING RIGHTS TO UP-CONVERTING PHOSPHOR COMPOSITIONS, METHODS AND
APPARATUSES.

      We  have  licensed  the  worldwide   rights  to   up-converting   phosphor
compositions, methods, and apparatuses for use in diagnostic applications, which
are the subject of nine issued U.S.  patents,  and of four pending  U.S.  patent
applications. Corresponding patents and patent applications have been granted or
issued  in  numerous  foreign  countries,   including,  for  example,   European
countries,  Japan, and Canada.  We cooperate with the licensor to prosecute such
patent applications and protect such patent rights. If the licensors do not meet
their obligations under the license  agreements or do not reasonably  consent to
sublicenses by us, or if the license agreement is terminated,

                                       7


we could lose the opportunity to develop the up-converting phosphor technology.

THE RECENT  ECONOMIC  DOWNTURN AND TERRORIST  ATTACKS MAY  ADVERSELY  AFFECT OUR
BUSINESS.

      Since the September 11, 2001 terrorist attacks,  the United States economy
has experienced a decline. Changes in economic conditions could adversely affect
our business. For example, in a difficult economic environment, customers may be
unwilling  or unable to invest in new  diagnostic  products or may perform  less
drug  testing  because of  declining  employment  levels.  A weakening  business
climate could also cause longer sales cycles and slower growth, and could expose
us to  increased  business or credit risk in dealing  with  customers  adversely
affected by economic conditions.

      The terrorist  attacks and any subsequent  governmental  response to these
attacks  could cause  further  economic  instability  or lead to further acts of
terrorism in the United States and  elsewhere.  These  actions  could  adversely
affect economic  conditions  outside the United States and reduce demand for our
products   internationally.   Terrorist  attacks  could  also  cause  regulatory
agencies, such as the FDA or agencies that perform similar functions outside the
United States,  to focus their resources on vaccines or other products  intended
to address the threat of  biological  or chemical  warfare.  This  diversion  of
resources  could delay our ability to obtain  regulatory  approvals  required to
manufacture,  market  or sell  our  products  in the  United  States  and  other
countries.


                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

      The shares listed under the column "Number of Shares Being Offered" in the
table  below  represent  the number of shares  that may be sold by each  selling
stockholder  pursuant  to this  prospectus.  Pursuant  to  Rule  416  under  the
Securities  Act, the  registration  statement of which this prospectus is a part
also covers any additional  shares of our common stock which become  issuable in
connection  with  such  shares  because  of any  stock  dividend,  stock  split,
recapitalization  or other similar  transaction  effected without the receipt of
consideration  which results in an increase in the number of outstanding  shares
of our common stock.

      We do not know when or in what amounts the selling  stockholders may offer
shares for sale. The selling  stockholders may not sell all or any of the shares
offered by this prospectus.  The selling stockholders may distribute the shares,
from  time to time,  to one or more of its  respective  limited  and/or  general
partners,  who may sell  shares  pursuant  to this  prospectus.  We may amend or
supplement  this prospectus from time to time to update the disclosure set forth
herein. Because the selling stockholders may from time to time offer all or some
of the shares  pursuant to this  offering,  and because  there are  currently no
agreements,  arrangements or  understandings  with respect to the sale of any of
the shares that will be held by the selling stockholders after completion of the
offering,  we cannot  estimate the number of the shares that will be held by the
selling stockholders after completion of the offering.  However, for purposes of
the table below, we have assumed that, after completion of the offering, none of
the shares covered by this prospectus will be held by the selling stockholders.


      The following  table sets forth,  to our  knowledge,  certain  information
regarding the beneficial  ownership of the shares of common stock by the selling
stockholders  as of January  31,  2002.  We  prepared  this  table  based on the
information  supplied  to us by the  selling  stockholders  named in the  table.
Beneficial  ownership  is  calculated  based  upon SEC  requirements  and is not
necessarily  indicative of beneficial ownership for any other purpose. The table
is based on 37,415,004  shares of our common stock outstanding as of January 31,
2002:

                              PLAN OF DISTRIBUTION

      The shares covered by this prospectus may be offered and sold from time to
time by the  selling  stockholders.  The term  "selling  stockholders"  includes
partners, pledgees, donees, transferees or other successors-in-interest  selling
shares received after the date of this prospectus from the selling  stockholders
as a pledge, gift,

                                       9


partnership  distribution  or other  non-sale  related  transfer.  To the extent
required,  we may  amend and  supplement  this  prospectus  from time to time to
describe a specific plan of distribution.

      The selling  stockholders will act independently of us in making decisions
with  respect  to the  timing,  manner  and  size  of  each  sale.  The  selling
stockholders  may make these sales at prices and under terms then  prevailing or
at prices related to the then current market price. The selling stockholders may
also make sales in negotiated transactions, including pursuant to one or more of
the following methods:

o     purchases by a broker-dealer as principal and resale by such broker-dealer
      for its own account pursuant to this prospectus;

o     ordinary  brokerage  transactions  and  transactions  in which the  broker
      solicits purchasers;

o     one or more block trades in which the  broker-dealer  will attempt to sell
      the shares as agent but may  position and resell a portion of the block as
      principal to facilitate the transaction;

o     an  over-the-counter  distribution  in  accordance  with the  rules of The
      Nasdaq National Market; and

o     in privately negotiated transactions.

      In connection with distributions of the shares or otherwise, the selling
      stockholders may:

o     enter into hedging  transactions  with  broker-dealers  or other financial
      institutions, which may in turn engage in short sales of the shares in the
      course of hedging the positions they assume;

o     sell the  shares  short and  redeliver  the shares to close out such short
      positions;

o     enter  into  option or other  transactions  with  broker-dealers  or other
      financial  institutions  which  require  the  delivery  to them of  shares
      offered by this prospectus, which they may in turn resell; and

o     pledge shares to a broker-dealer  or other financial  institution,  which,
      upon a default, they may in turn resell.

      In  addition,  the selling  stockholders  may sell all or a portion of the
shares that qualify for sale pursuant to Rule 144 and 145 of the Securities Act,
as amended, under Rule 144 or 145 rather than pursuant to this prospectus.

      Sales through  brokers may be made by any method of trading  authorized by
any  stock  exchange  or market on which  the  shares  may be listed or  quoted,
including  block  trading  in  negotiated  transactions.  Without  limiting  the
foregoing,  such  brokers  may act as  dealers by  purchasing  any or all of the
shares covered by this prospectus,  either as agents for others or as principals
for their own accounts,  and reselling such shares pursuant to this  prospectus.
The selling  stockholders may effect such transactions  directly,  or indirectly
through  underwriters,  broker-dealers  or  agents  acting on their  behalf.  In
effecting sales,  broker-dealers  or agents engaged by the selling  stockholders
may arrange for other  broker-dealers  to participate.  Broker-dealers or agents
may receive commissions, discounts or concessions from the selling stockholders,
in amounts to be negotiated immediately prior to the sale.

      In  offering  the  shares   covered  by  this   prospectus,   the  selling
stockholders,  and any broker-dealers and any other participating broker-dealers
who  execute  sales  for  the  selling   stockholders,   may  be  deemed  to  be
"underwriters" within the meaning of the Securities Act in connection with these
sales. Any profits realized by the selling  stockholders and the compensation of
such broker-dealers may be deemed to be underwriting discounts and commissions.

      In order to comply with the securities laws of certain states,  the shares
must be sold in those  states only  through  registered  or licensed  brokers or
dealers.  In addition,  in certain states the shares may not be sold unless they
have  been  registered  or  qualified  for  sale in the  applicable  state or an
exemption from the registration or qualification requirement is available and is
complied with.

                                       10



      We have advised the selling stockholders that the anti-manipulation  rules
of  Regulation  M under  the  Exchange  Act may  apply to sales of shares in the
market and to the activities of the selling  stockholders and their  affiliates.
In  addition,  we will make copies of this  prospectus  available to the selling
stockholders for the purpose of satisfying the prospectus delivery  requirements
of the Securities Act. The selling  stockholders may indemnify any broker-dealer
that  participates  in  transactions  involving  the sale of the shares  against
certain liabilities, including liabilities arising under the Securities Act.

      At the time a particular  offer of shares is made,  if  required,  we will
distribute a prospectus supplement that will set forth:

o     the number of shares being offered;

o     the terms of the offering,  including the name of any underwriter,  dealer
      or agent;

o     the purchase price paid by any underwriter;

o     any discount, commission and other underwriter compensation;

o     any discount, commission or concession allowed or reallowed or paid to any
      dealer; and

o     the proposed selling price to the public.

      We have agreed to  indemnify  the  selling  stockholders  against  certain
liabilities, including certain liabilities under the Securities Act.

      We have  agreed  with the selling  stockholders  to keep the  registration

                                 INDEMNIFICATION

      Delaware law  authorizes a corporation  to limit or eliminate the personal
liability  of its  directors  for  monetary  damages for breach of a  director's
fiduciary  duty of care.  Delaware  law further  enables  corporations  to limit
available relief to equitable remedies such as injunction or rescission.  Absent
the  limitations  authorized by Delaware  law,  directors  are  accountable  for
monetary  damages for conduct  constituting  gross negligence in the exercise of
their duty of care. Our Certificate of Incorporation limits the liability of our
directors to the fullest  extent  permitted by Delaware  law.  Accordingly,  our
directors will not be personally  liable to us or our  stockholders for monetary
damages for breach of a fiduciary  duty as a director,  except for liability for
breach of the duty of loyalty,  for acts or omissions  not in good faith or that
involve  intentional  misconduct  or a knowing  violation  of law,  for unlawful
payments of dividends or unlawful  stock  repurchases or redemptions as provided
in Section 174 of the General  Corporation Law of the State of Delaware,  or for
any transaction in which a director has derived an improper personal benefit.

      Our Bylaws  require us to  indemnify  to the fullest  extent  permitted by
Delaware  law any person who is a party or is  threatened  to be made a party to
any action,  suit or proceeding by reason of the fact that such person is or was
our director,  officer, employee or agent, or is serving as a director, officer,
employee or agent of another enterprise at our request.  Indemnification is not,
however, permitted under the Bylaws unless the person acted in good faith and in
a manner  that such  person  reasonably  believed to be in or not opposed to our
best interests and, with respect to any criminal action or proceeding, that such
person had no reasonable  cause to believe such  person's  conduct was unlawful.
The  Bylaws  further  provide  that we shall not  indemnify  any  person for any
liabilities  or expenses  incurred by such person in connection  with an action,
suit or proceeding by or in the right of OraSure  Technologies in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable to us,  unless and only to the extent that the court in which the action,
suit or  proceeding  is  brought  determines  that the  person  is  entitled  to
indemnity for such expenses.  The indemnification  provided by the Bylaws is not
exclusive  of any other  rights to which those  seeking  indemnification  may be
otherwise entitled.

      We have  entered  into  indemnification  agreements  with  certain  of our
directors  and officers.  The  indemnification  agreements  provide that we will
indemnify  these  directors and officers  against all  liabilities  and expenses
actually  and  reasonably  incurred  in  connection  with  any  action,  suit or
proceeding  (including an action by or in the right of OraSure  Technologies) to
which any of them is, was or at any time becomes a party, or is threatened to be
made a party,  by reason of their status as a director or officer,  or by reason
of their  serving  or having  served  at the  request  or on  behalf of  OraSure
Technologies as a director, officer, trustee or in any other comparable position
of any other  enterprise to the fullest extent allowed by law. No indemnity will
be  provided  under the  indemnification  agreements  for any  amounts for which
indemnity  is  provided by any other  indemnification  obligation  or  insurance
maintained by us or otherwise.  Indemnity  will not be available to any director
or officer on account of conduct  which is finally  adjudged  by a court to have
been knowingly  fraudulent,  deliberately  dishonest or willful  misconduct.  No
indemnification  will be provided if a final court adjudication  determines that
such  indemnification is not lawful, or in respect of any suit in which judgment
is rendered  against any director or officer for an  accounting  of profits made
from a purchase or sale of  securities of OraSure  Technologies  in violation of
Section  16(b) of the  Exchange  Act or of any similar law, or on account of any
remuneration  paid to any director or officer which is  adjudicated to have been
paid in violation of law.

      We have also obtained director's and officer's liability insurance.

Item 15. Indemnification of Directors and Officers

      Delaware law  authorizes a corporation  to limit or eliminate the personal
liability  of its  directors  for  monetary  damages for breach of a  director's
fiduciary  duty of care.  Delaware  law further  enables  corporations  to limit
available relief to equitable remedies such as injunction or rescission.  Absent
the  limitations  authorized by Delaware  law,  directors  are  accountable  for
monetary  damages for conduct  constituting  gross negligence in the exercise of
their duty of care. Our Certificate of Incorporation limits the liability of our
directors to the fullest  extent  permitted by Delaware  law.  Accordingly,  our
directors will not be personally  liable to us or our  stockholders for monetary
damages for breach of a fiduciary  duty as a director,  except for liability for
breach of the duty of loyalty,  for acts or omissions  not in good faith or that
involve  intentional  misconduct  or a knowing  violation  of law,  for unlawful
payments of dividends or unlawful  stock  repurchases or redemptions as provided
in Section 174 of the General  Corporation Law of the State of Delaware,  or for
any transaction in which a director has derived an improper personal benefit.

      Our Bylaws  require us to  indemnify  to the fullest  extent  permitted by
Delaware  law any person who is a party or is  threatened  to be made a party to
any action,  suit or proceeding by reason of the fact that such person is or was
our director,  officer, employee or agent, or is serving as a director, officer,
employee or agent of another enterprise at our request.  Indemnification is not,
however, permitted under the Bylaws unless the person acted in good faith and in
a manner  that such  person  reasonably  believed to be in or not opposed to our
best interests and, with respect to any criminal action or proceeding, that such
person had no reasonable  cause to believe such  person's  conduct was unlawful.
The  Bylaws  further  provide  that we shall not  indemnify  any  person for any
liabilities  or expenses  incurred by such person in connection  with an action,
suit or proceeding by or in the right of OraSure  Technologies in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable to us,  unless and only to the extent that the court in which the action,
suit or  proceeding  is  brought  determines  that the  person  is  entitled  to
indemnity for such expenses.  The indemnification  provided by the Bylaws is not
exclusive  of any other  rights to which those  seeking  indemnification  may be
otherwise entitled.

      We have  entered  into  indemnification  agreements  with  certain  of our
directors  and officers.  The  indemnification  agreements  provide that we will
indemnify  these  directors and officers  against all  liabilities  and expenses
actually  and  reasonably  incurred  in  connection  with  any  action,  suit or
proceeding  (including an action by or in the right of OraSure  Technologies) to
which any of them is, was or at any time becomes a party, or is threatened to be
made a party,  by reason of their status as a director or officer,  or by reason
of their  serving  or having  served  at the  request  or on  behalf of  OraSure
Technologies as a director, officer, trustee or in any other comparable position
of any other  enterprise to the fullest extent allowed by law. No indemnity will
be  provided  under the  indemnification  agreements  for any  amounts for which
indemnity  is  provided by any other  indemnification  obligation  or  insurance
maintained by us or otherwise.  Indemnity  will not be available to any director
or officer on account of conduct  which is finally  adjudged  by a court to have
been knowingly  fraudulent,  deliberately  dishonest or willful  misconduct.  No
indemnification  will be provided if a final court adjudication  determines that
such  indemnification is not lawful, or in respect of any suit in which judgment
is rendered  against any director or officer for an  accounting  of profits made
from a purchase or sale of  securities of OraSure

                                      II-1


Technologies in violation of Section 16(b) of the Exchange Act or of any similar
law, or on account of any remuneration  paid to any director or officer which is
adjudicated to have been paid in violation of law.

      We have also obtained director's and officer's liability insurance.

Item 17. Undertakings

      The undersigned registrant hereby undertakes:

            (1) To file,  during any  period in which  offers or sales are being
made, a post-effective amendment to this Registration Statement:

                  (i) To include any prospectus  required by Section 10(a)(3) of
            the Securities Act;

                  (ii) To reflect in the  prospectus any facts or events arising
            after the effective date of the registration  statement (or the most
            recent post-effective  amendment thereof) which,  individually or in
            the aggregate, represent a fundamental change in the information set
            forth in the Registration Statement.  Notwithstanding the foregoing,
            any  increase or decrease  in volume of  securities  offered (if the
            total dollar value of securities offered would not exceed that which
            was  registered)  and any deviation  from the low or high end of the
            estimated  maximum  offering  range may be  reflected in the form of
            prospectus filed with the Commission  pursuant to Rule 424(b) if, in
            the  aggregate,  the changes in volume and price  represent  no more
            than 20% change in the maximum aggregate offering price set forth in
            the  "Calculation  of  Registration  Fee"  table  in  the  effective
            registration statement; and


                  (iii) To include any material  information with respect to the
            plan of distribution  not previously  disclosed in the  Registration
            Statement  or  any  material  change  to  such  information  in  the
            Registration Statement;

                                      II-2



            provided,  however,  that paragraphs (i) and (ii) above do not apply
            if the  Registration  Statement  is on Form  S-3 or Form S-8 and the
            information required to be included in a post-effective amendment by
            those  paragraphs  is  contained in periodic  reports  filed with or
            furnished to the Commission by the Registrant pursuant to Section 13
            or  Section  15(d) of the  Exchange  Act that  are  incorporated  by
            reference in the Registration Statement.

            (2) That,  for the purpose of  determining  any liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3)  To  remove  from  registration  by  means  of a  post-effective
amendment  any of the  securities  being  registered  which remain unsold at the
termination of the offering.

      The  undersigned  Registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act that is  incorporated  by reference in the  Registration  Statement
shall be deemed to be a new  registration  statement  relating to the securities
offered  therein,  and the  offering  of such  securities  at that time shall be
deemed to be the initial bona fide offering thereof.

      Insofar as  indemnification  for liabilities  arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been  advised  that in the  opinion of the SEC such  indemnification  is against
public policy as expressed in the Act and is, therefore,  unenforceable.  In the
event that a claim for indemnification  against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling  person of the Registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the securities being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                                      II-3
