                          NOTES TO FINANCIAL STATEMENTS
                                   (unaudited)

1. BASIS OF PRESENTATION

   Trimeris,  Inc.  (the  "Company")  was  incorporated  on  January  7, 1993 to
discover  and develop  novel  therapeutic  agents that block viral  infection by
inhibiting  viral fusion with host cells.  These financial  statements have been
prepared in accordance with Statement of Financial  Accounting  Standards No. 7,
"Accounting and Reporting by Development  Stage  Enterprises,"  to recognize the
fact  that  the  Company  is  devoting  substantially  all  of  its  efforts  to
establishing a new business and planned principal operations have not commenced.

   The  accompanying  unaudited  financial  statements  have  been  prepared  in
accordance  with  generally  accepted   accounting   principles  and  applicable
Securities   and  Exchange   Commission   regulations   for  interim   financial
information.  Certain information and footnote  disclosures normally included in
financial  statements  prepared in accordance with generally accepted accounting
principles  have been  condensed  or  omitted  pursuant  to the  Securities  and
Exchange  Commission  rules and regulations.  In the opinion of management,  all
adjustments  (consisting only of normal recurring  adjustments)  necessary for a
fair  presentation  of financial  position and results of  operations  have been
made.  Operating  results for interim periods are not necessarily  indicative of
results which may be expected for a full year. The information  included in this
Form 10-Q should be read in conjunction  with the Risk Factors and  Management's
Discussion  and  Analysis  of  Financial  Condition  and  Results of  Operations
sections and the 2000  financial  statements  and notes thereto  included in the
Company's 2000 Annual Report on Form 10-K filed with the Securities and Exchange
Commission on April 2, 2001.

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

2. BASIC NET INCOME (LOSS) PER SHARE

   In accordance with SFAS No. 128, "Earnings Per Share" ("SFAS No. 128"), basic
loss per common share is calculated by dividing net loss by the weighted-average
number of common shares  outstanding  for the period after  certain  adjustments
described  below.  Diluted  net income per common  share  reflects  the  maximum
dilutive  effect of common stock issuable upon exercise of stock options,  stock
warrants,  and conversion of preferred stock.  Diluted net loss per common share
is not  shown,  as  common  equivalent  shares  from  stock  options,  and stock
warrants,  would  have an  antidilutive  effect.  At March 31,  2001  there were
1,914,000  options to purchase common stock  outstanding and 362,000 warrants to
purchase common stock outstanding.

   Interest  of  approximately  $54,000  and  $45,000  was paid during the three
months ended March 31, 2000 and 2001,  respectively.  Capital leases of $331,000
and $0 were  incurred  for the  three  months  ended  March  31,  2000 and 2001,
respectively for the purchase of new furniture and equipment.

4. PUBLIC OFFERINGS OF STOCK

   In October 1997,  the Company  closed its initial  public  offering of common
stock at $12 per share. The net proceeds of the offering, including the proceeds
received in  connection  with the exercise of the  Underwriters'  over-allotment
option which closed in November  1997,  were  approximately  $34.5 million after
deducting applicable issuance costs and expenses.  In connection with the public
offering,  all the  outstanding  preferred  stock was converted  into  6,261,615
shares of the Company's common stock.

   In June 1999, the Company closed a public  offering of common stock at $11.75
per share. The net proceeds of the offering,  including the proceeds received in
connection with the exercise of the Underwriters'  over-allotment  option,  were
approximately  $31.4  million  after  deducting  applicable  issuance  costs and
expenses.

   In February  2000,  the Company  closed a private  placement  of 1.75 million
shares of common  stock at $40.50 per share.  The net  proceeds of the  offering
were approximately  $66.6 million after deducting  applicable issuance costs and
expenses.

5. ROCHE COLLABORATION

   In July 1999, the Company  announced an agreement with F.  Hoffmann-La  Roche
Ltd to develop and market T-20 and T-1249  worldwide.  In the United  States and
Canada,  the  Company  and Roche will share  equally  development  expenses  and
profits for the two fusion  inhibitors.  Outside of these two  countries,  Roche
will fund all  development  costs and pay the Company  royalties on net sales of
these products. Roche made an initial cash payment to the Company of $10 million
during 1999 and a milestone payment of $2 million in 2000. Roche will provide up
to  an  additional  $56  million  in  cash  and  funding  upon   achievement  of
developmental,  regulatory and commercial  milestones.  In accordance with Staff
Accounting  Bulletin No. 101, the initial cash payment,  net of the $5.4 million
fair value of the warrant granted to Roche, is being amortized into revenue over
the research and development term of the Roche agreement.

6. SUBSEQUENT EVENT

   In May 2001,  the Company  closed a private  placement of  approximately  1.4
million  shares of common  stock at $33.00 per share.  The net  proceeds  of the
offering were approximately  $43.4 million after deducting  applicable  issuance
costs and expenses.

Item 2.  Management's Discussion and Analysis of Financial Condition  and
         ----------------------------------------------------------------
         Results of Operations
         ---------------------

   This  discussion  of our  financial  condition  and the results of operations
should be read  together  with the  financial  statements  and  notes  contained
elsewhere  in this Form  10-Q.  Certain  statements  in this  section  and other
sections are  forward-looking.  While we believe these  statements are accurate,
our business is dependent on many  factors,  some of which are  discussed in the
"Risk  Factors" and  "Business"  sections of our 2000 Annual Report on Form 10-K
filed with the  Securities  and  Exchange  Commission  on April 2,  2001.  These
factors include, but are not limited to: that we are an early stage company with
an  uncertain  future;  that we have  never  made money and expect our losses to
continue;  that we will need to raise additional funds in the near future;  that
our quarterly  operating  results are subject to fluctuations and you should not
rely  on  them as an  indication  of our  future  results;  that we are  heavily
dependent on our lead product candidate,  T-20; that the success of T-20 depends
on the results of our Phase III clinical trials currently in progress;  that our
success in  commercializing  T-20 and T-1249  depends on our  relationship  with
Roche;  that we face many  uncertainties  relating to our human  clinical  trial
results and clinical trial  strategy;  that we have no experience  manufacturing
pharmaceutical  products;  that we face risks associated with manufacturing T-20
and T-1249;  that HIV may develop  resistance to our drug  candidates;  that our
business is based on novel technology and is highly risky and uncertain; that we
are dependent on third-party  contract research  organizations;  that we have no
sales,  marketing or distribution  capabilities;  that our stock price is highly
volatile;  that we depend on collaborations and licenses with others; that there
is  uncertainty  relating  to  third-party  reimbursement,  health  care  reform
measures, and recent developments in Africa which could limit the amount we will
be able to charge for our products;  that there is uncertainty regarding patents
and proprietary rights; that we are subject to extensive government  regulation;
that our  products  may not receive  regulatory  approval;  that we face intense
competition;  that our products may not achieve market  acceptance;  that we use
hazardous  materials;  that we are exposed to product  liability risks;  that we
depend upon  certain  key  personnel  and face risks  relating to our ability to
attract  and retain key  personnel;  that  future  sales of common  stock by our
existing  stockholders or key management could adversely affect our stock price;
that we have implemented certain anti-takeover  provisions;  and that our actual
results could differ  materially from those  anticipated in our  forward-looking
statements.  Many of these  factors  are beyond our control and any of these and
other  factors  could  cause  actual  results  to  differ  materially  from  the
forward-looking  statements  made in this  10-Q.  The  results  of our  previous
clinical trials are not necessarily indicative of the results of future clinical
trials.  We  undertake  no  obligation  to release  publicly  the results of any
revisions to the  statements  contained  in this Form 10-Q to reflect  events or
circumstances that occur subsequent to the date hereof.

Overview

   We began our operations in January 1993 and are a development  stage company.
Accordingly,   we  have  a  limited  operating  history.  Since  our  inception,
substantially all of our resources have been dedicated to:

o  the development, patenting, preclinical testing and clinical trials of T-20
   and T-1249,

o  the development of a manufacturing process for T-20 and T-1249,

o  production of drug material for future clinical trials, and

o  research and development and preclinical testing of other potential product
   candidates.

   We have  lost  money  since  inception  and,  as of March  31,  2001,  had an
accumulated  deficit of approximately  $133.8 million.  We have received revenue
only from federal small business innovative research grants,  otherwise known as
SBIR grants, an investigative contract, and an initial collaboration payment and
a milestone  payment from Roche, and have not generated any revenue from product
sales or  royalties.  We may never  generate any revenue  from product  sales or
royalties.

                                       6




   Development of current and future drug  candidates  will require  significant
additional,  time-consuming  and costly  research and  development,  preclinical
testing and extensive  clinical  trials prior to  submission  of any  regulatory
application  for commercial use. We expect to incur  substantial  losses for the
foreseeable   future  and  expect   losses  to  increase  as  our  research  and
development,  preclinical  testing,  drug  production and clinical trial efforts
expand.  The amount and timing of our  operating  expenses  will  depend on many
factors, including:

o  the status of our research and development activities,

o  product candidate discovery and development efforts, including preclinical
   testing and clinical trials,

o  the timing of regulatory actions,

o  the costs involved in preparing, filing, prosecuting, maintaining, protecting
   and enforcing patent claims and other proprietary rights,

o  our ability to work with Roche to manufacture, develop, sell, market and
   distribute T-20 and T-1249,

o  technological and other changes in the competitive landscape,

o  changes in our existing or research and development relationships and
   strategic alliances,

o  development of any future research and development relationships or strategic
   alliances,

o  evaluation of the commercial viability of potential product candidates, and

o  other factors, many of which are outside of our control.

   As a result,  we believe that  period-to-period  comparisons of our financial
results  in the  future  are not  necessarily  meaningful.  The past  results of
operations and results of previous clinical trials should not be relied on as an
indication of future performance.  If we fail to meet the clinical and financial
expectations  of  securities  analysts and  investors,  it could have a material
adverse  effect on the market price of our common stock.  Our ability to achieve
profitability  will depend, in part, on our own or our  collaborative  partner's
ability to  successfully  develop  and obtain  regulatory  approval  for T-20 or
T-1249 and other  product  candidates,  and our ability to develop the capacity,
either internally or through  relationships with third parties,  to manufacture,
sell,  market and distribute  approved  products,  if any. We may never generate
significant revenues or achieve profitable operations.

Results of Operations

COMPARISON OF THREE MONTHS ENDED MARCH 31, 2000 AND 2001

REVENUE.  Total revenue increased from $210,000 for the three months ended March
31, 2000 to $326,000 for the three months  ended March 31, 2001.  Total  revenue
for the three months ended March 31, 2000 represents the amortization of the $10
million initial  collaboration payment from Roche, net of the $5.4 million value
assigned to the warrant issued to Roche,  over the research and development term
of the  agreement.  Total  revenue  for the three  months  ended  March 31, 2001
includes this  amortization and amortization of a $2.0 million milestone payment
received from Roche in 2000.

RESEARCH AND DEVELOPMENT EXPENSES.  Total research and development expenses were
$8.5  million and $10.6  million for the three  months  ended March 31, 2000 and
2001,  respectively.  Gross research and development expenses excluding non-cash
compensation  charges  increased from $5.0 million during the three months ended
March 31, 2000 to $13.8  million  during the three  months  ended March 31, 2001
because we:

o  continued two Phase III clinical trials for T-20,

o  continued four Phase II clinical trials for T-20,

o  continued a Phase I clinical trial for T-1249,

o  continued manufacturing process development and purchase of drug material
   from third party manufacturers to supply future clinical trials, and

o  increased the number of our personnel to support these activities.

Non-cash  compensation changed from $3.5 million in expense for the three months
ended March 31, 2000 to $3.3  million in expense  reversal  for the three months
ended March 31, 2001  primarily  due to the effect that  decreases in the market
value  of  our  stock  during  the  quarter  ended  March  31,  2001  had on the
calculation  of this amount under  Emerging  Issues Task Force  ("EITF")  96-18,
"Accounting for Equity  Instruments  That Are Issued to Other Than Employees for
Acquiring,  or in Conjunction with Selling, Goods or Services" for stock options
granted to non-employees.  Total research and development expenses include gross
research and  development  expenses less Roche's share of development  costs for
T-20 and T-1249.  Under our  collaboration  agreement,  we and Roche  shared the
development  costs incurred  during the period from July 1, 1999 until March 31,
2001 for T-20 and T-1249 equally.

Total  research   personnel  were  55  and  66  at  March  31,  2000  and  2001,
respectively.  We expect total research and development expenses,  which are net
of the  reimbursements  for T-20 and T-1249  development  costs from  Roche,  to
increase substantially in the future due to:

o  expansion of the two Phase III clinical trials for T-20,

o  expanded clinical trials for T-20, T-1249 and other product candidates,

o  the manufacture of drug material for these trials,

o  increased preclinical research and testing of potential product candidates,
   and

o  increased number of personnel to support these activities.


                                       8




GENERAL AND ADMINISTRATIVE  EXPENSES.  Total general and administrative expenses
were $5.2 million and $2.8 million for the three months ended March 31, 2000 and
2001,  respectively.  Expenses excluding non-cash compensation charges increased
from $1.6  million for the three months ended March 31, 2000 to $2.3 million for
the three months ended March 31, 2001 because in 2001 we:

o  performed market research and pre-marketing activities which are shared
   equally with Roche,

o  added personnel to support our growth, and

o  incurred professional fees to support our growth.

Non-cash  compensation  expense decreased from $3.6 million for the three months
ended  March 31,  2000 to  $490,000  for the three  months  ended March 31, 2001
primarily  due to the effect  that  decreases  in the market  value of our stock
during the quarter ended March 31, 2001 had on the  calculation  of this expense
under  EITF  96-18  for  stock  options  granted  to  non-employees.  We  expect
administrative  expenses to  increase  in the future to support the  anticipated
expansion of product development activities.

OTHER INCOME (EXPENSE).  Other income (expense)  consists of interest income and
expense.  Total other  income was $1.2  million  and $1.4  million for the three
months  ended March 31, 2000 and 2001,  respectively.  The  increase  was due to
increased interest income because of higher cash and investment  balances during
the three months ended March 31, 2001 due to our stock offering, which closed in
February 2000.

Liquidity and Capital Resources

     Since  inception,  we have financed our  operations  primarily  through the
private placement of equity  securities,  the issuance of notes to stockholders,
equipment lease financing, an initial public offering of common stock in October
1997, a public offering of common stock in June 1999, and a private placement of
common stock in February  2000.  Net cash used by operating  activities was $9.7
million and $18.0  million for the three  months  ended March 31, 2000 and 2001,
respectively.  The cash used by operating  activities was used primarily to fund
research and development relating to T-20, T-1249, and other product candidates,
and  increased  for the three  months  ended March 31, 2001 because of increased
research and development activities.  Cash used by investing activities was $5.8
million for the three months ended March 31,  2000.  Cash  provided by investing
activities  was $10.2  million for the three months  ended March 31,  2001.  The
amount used for the three months ended March 31, 2000 resulted from the purchase
of short-term  investments as a result of our private  placement of common stock
in February 2000. The amount  provided for the three months ended March 31, 2001
resulted from the net sale of short-term investments to fund our operations.

     As of March 31, 2001, we had $75.7 million in cash and cash equivalents and
short-term-investments,  compared to $93.4 million as of December 31, 2000.  The
decrease is primarily  due to the $18.0  million  used by  operating  activities
during the three months ended March 31, 2001.

     In July 2000,  we entered  into a derivative  transaction  with a financial
institution  that may be settled by selling up to 300,000 shares of our stock to
the financial  institution at prices  significantly higher than the market price
per share of our stock at the  inception of the  transaction.  We received  $2.8
million in proceeds that were accounted for as an increase to additional paid-in
capital in accordance with generally accepted accounting  principles at the time
of  the  transaction.   Concurrently,   we  entered  into  a  second  derivative
transaction with the same financial institution on shares of our common stock at
no net premium to either party.  Under this transaction,  we may elect to settle
by issuing up to 125,000 shares of our common stock to the financial institution
at prescribed prices  significantly higher than the market price of our stock at
the date of the  transaction  and receive a net cash payment from the  financial
institution.  Alternatively,  we have the option to settle  these  contracts  by
making a cash payment to the financial  institution for the underlying  value of
the derivative contracts to the financial institution on the settlement date. We
intend to settle  the  contracts  by  issuing  shares.  In  December  2000 these
contracts were amended to allow settlement in unregistered  shares of our common
stock. All of these derivative  transactions  expire or mature in July 2001. The
financial  institution  has advised us that it has  engaged and may  continue to
engage in transactions, including the buying and selling of shares of our common
stock, to offset its risks related to these  transactions,  which may or may not
affect the market price of our stock.

                                       9


     We have experienced negative cash flows from operations since our inception
and do not  anticipate  generating  sufficient  positive  cash flows to fund our
operations   in  the   foreseeable   future.   Although  we  expect  to  receive
reimbursement  for 50% of the development  costs for T-20 and T-1249 from Roche,
we have  expended,  and expect to continue to expend in the future,  substantial
funds to pursue our product  candidate and compound  discovery  and  development
efforts, including:

o  expenditures for clinical trials of T-20, T-1249 and other product
   candidates,

o  research and development and preclinical testing of other product candidates,

o  manufacture of drug material, and

o  the development of our proprietary technology platform.

     As of March 31, 2001, we had commitments of approximately  $12.7 million to
purchase product candidate  materials and fund various clinical studies over the
next 13 months.  Substantially all of these  expenditures will be shared equally
by Roche under our collaborative agreement.  Under this collaborative agreement,
we are obligated to share equally the future  development  expenses for T-20 and
T-1249.  We also  expect to have  capital  expenditures  of  approximately  $2.5
million  during the remainder of 2001.  Our share of these  expenditures  may be
financed with capital or operating leases, debt or working capital. In May 2001,
we closed a private  placement  of  approximately  1.4 million  shares of common
stock at a price of $33.00 per share.  The net  proceeds  of the  offering  were
approximately  $43.4  million  after  deducting  applicable  issuance  costs and
expenses.  We expect that our  existing  capital  resources,  together  with the
interest  earned  thereon,  will be adequate  to fund our  capital  requirements
through  2001.  We believe that  substantial  additional  funds will be required
after 2001.

     We will be required to obtain additional funds, which may be raised through
equity or debt  financings.  Since our initial public  offering in 1997, we have
obtained the majority of our funding through public or private  offerings of our
common stock. The public capital markets in which shares of our common stock are
traded have declined during the first quarter of 2001 and the general ability of
companies to obtain additional financing has become more difficult than in 2000.
If and when we raise funds by selling equity, our stockholders'  interest may be
diluted.  Any debt  financings  may  contain  restrictive  terms  that limit our
operating flexibility.  Additionally or alternatively, we may have to attempt to
obtain funds through arrangements with new or existing  collaborative  partners.
These  partners  may  require us to  relinquish  rights to our  technologies  or
product  candidates  or to reduce our share of  potential  profits.  If adequate
funds are not available through debt or equity financings, we may be required to
delay, scale-back or eliminate certain preclinical testing,  clinical trials and
research and  development  programs,  including our  collaborative  efforts with
Roche.  This could have a material  adverse  effect on our  business,  financial
condition or results of operations.

     Our future capital  requirements  and the adequacy of available  funds will
depend on many factors, including the availability of funds from Roche under our
collaboration agreement, the condition of public capital markets, the results of
clinical  trials  relating to T-20 and  T-1249,  the  progress  and scope of our
product development  programs,  the magnitude of these programs,  the results of
preclinical  testing and clinical  trials,  the need for  additional  facilities
based on the  results of these  clinical  trials and other  product  development
programs,  changes  in  the  focus  and  direction  of our  product  development
programs,  the costs  involved in preparing,  filing,  processing,  maintaining,
protecting and enforcing patent claims and other  intellectual  property rights,
competitive factors and technological  advances, the cost, timing and outcome of
regulatory reviews,  changes in the requirements of the FDA,  administrative and
legal  expenses,  evaluation of the  commercial  viability of potential  product
candidates and compounds,  the  establishment of capacity,  either internally or
through  relationships with third parties, for manufacturing,  sales,  marketing
and distribution functions,  and other factors, many of which are outside of our
control.

Factors That May Affect Future Results and Financial Condition

Clinical Development

     The following  discussion  highlights  certain  aspects of our on-going and
planned  clinical  development  programs.  The results of our previous  clinical
trials are not necessarily indicative of the results of future clinical trials.

    T-20

     We are developing T-20, our first drug candidate for HIV fusion inhibition,
which has been granted fast track  designation  by the FDA. T-20 is currently in
Phase III clinical trials.

     Ongoing T-20 Clinical Trials

     Phase III -- T20-301.  In November 2000, we began enrollment of T20-301,  a
48-week Phase III clinical trial in North America, Mexico, and Brazil, that will
evaluate  the  safety  and  pharmacokinetics  of T-20 in up to 525  HIV-infected
patients  who had  previously  used  all  three  classes  of  currently-approved
anti-HIV drugs. In this trial,  patients will be randomly assigned to receive an
optimized  background  regimen of other  anti-HIV  drugs alone or in combination
with twice  daily  subcutaneous  injection  delivering  90 mg of T-20 each.  The
background  regimen will be optimized based on the genotype and phenotype of the
patient's  virus.  T20-301 is ongoing  and we expect  data from this trial to be
available in the future.

     Phase III -- T20-302.  In January 2001, we began  enrollment of T20-302,  a
48-week Phase III clinical trial in Western  Europe and Australia.  The protocol
for T20-302 is substantially  similar to T20-301 and will also involve up to 525
HIV-infected patients.

     Phase II --  T20-205.  T20-205 is an  ongoing  Phase II trial that has been
extended  beyond its initial 48-week  protocol.  This trial involves 71 patients
from earlier T-20 Phase I/II studies.  In T20-205, 50 mg of T-20 is administered
via subcutaneous injection in combination with oral anti-HIV drugs. Combinations
of the oral anti-HIV  drugs were  optimized  based on genotypic  and  phenotypic
analysis  of each  patient's  virus.

     At 48 weeks, 41 of the 71 patients were evaluated. No patients discontinued
this trial due to T-20 related toxicity, but 14 patients discontinued this trial
due to a virologic failure, or HIV viral load less than -0.5 log10 from baseline
at the beginning of the trial. At 48 weeks, 23 of 41 patients or 56% exhibited a
decrease in HIV viral load of more than 1.0 log(10) or less than 400  copies/ml,
and 16 of 41 patients or 39% had an HIV viral load below 400 copies/ml.

     At 48 weeks,  the patients  continued to tolerate  T-20.  Data suggest that
T-20 in  combination  with other  anti-HIV drugs may contribute to a lasting and
clinically  relevant  suppression of HIV in the blood in patients with extensive
prior anti-HIV treatment.

     Phase II -- T20-204.  In November 1999, in collaboration  with the Division
of AIDS of the National Institute for Allergy and Infectious Diseases, or NIAID,
we  initiated  a Phase I/II  trial to  evaluate  the  safety,  tolerability  and
pharmacokinetics  of T-20 in children  living with HIV  infection.  The trial is
managed by the  Pediatric  AIDS  Clinical  Trial Group,  or PACTG,  and has been
designated as a fast-track study within the PACTG system.

     The trial is being  conducted  in two parts and has  enrolled 12  pediatric
patients ages three to 12. The first part, week one,  examined safety parameters
to establish a well-tolerated pediatric dose that provides target concentrations
of T-20 in the blood. The second part, conducted over a twenty-four week period,
evaluates  the  safety and  tolerability  of T-20 via twice  daily  subcutaneous
injections in combination with a background of other anti-HIV drugs selected for
each particular patient based on the patient's prior treatment  history.  Within
seven days of dosing with T-20 as an addition to an inactive  anti-HIV  therapy,
patients in the highest dose group had an average reduction in HIV viral load of
approximately  10 fold from  baseline at the  beginning  of the trial.  At eight
weeks, three of four patients in the lowest dose group and six of seven patients
in the highest dose group continued to maintain a similar reduction in HIV viral
load from  baseline at the  beginning of the trial.  Data at the 12 week interim
analysis suggest that short-term  subcutaneous  dosing of T-20 is well tolerated
in pediatric  patients.

                                       11


     Of the 12 patients  enrolled in the trial,  one patient  withdrew due to an
aversion to the method of administration of T-20 via subcutaneous injection.

     T20-204 is ongoing  and the next  analysis  of data is  scheduled  to occur
based on 24-week data.

     Phase II -- T20-206. In June 1999, we initiated T20-206, a 48 week Phase II
clinical trial for T-20 to assess the antiviral activity and long-term safety of
T-20 when used in combination  with other anti-HIV drugs.  The trial consists of
four treatment  groups:

o  arm A who received only the  background  regimen of 300 mg of abacavir  twice
   daily,  1200 mg of amprenavir  twice daily,  200 mg of ritonavir twice daily,
   600 mg of  efavirenz  once daily,  and
o  arms B, C and D who received 50mg,  75mg, and 100 mg,  respectively,  of T-20
   via twice daily subcutaneous injection in addition to the background regimen.

T20-206  enrolled 71  HIV-infected  individuals  at several  sites in the United
States. At entry in the trial, all enrolled patients had prior exposure to NRTIs
and PIs, but no prior exposure to NNRTIs.

     In February  2001, we announced 16 week interim data from T20-206.  At week
16, the median  maximum  reduction  in HIV viral load from the viral load at the
beginning  of the trial for all  patients  ranged from 2.16  log(10) or 99.3% to
2.84  log(10) or 99.9%  across the T-20  treatment  groups.  The median  maximum
reduction  in HIV viral load for  patients  with HIV viral  loads  greater  than
20,000 copies/microliter at the beginning of the trial was 2.64 log(10) or 99.8%
across the T-20  treatment  groups  versus 1.55 log(10) or 97.2% for the control
arm only. Data from 16 weeks suggest that T-20 is safe and active in combination
with other anti-HIV therapy.

     T20-206 is ongoing  and the next  analysis  of data is  scheduled  to occur
based on 48-week data.

     Phase II -  T-20-208.  In March 2000,  we  initiated  T-20-208,  a Phase II
clinical  trial for T-20 that will evaluate  alternative  formulations  of T-20,
which could lead to a simpler  dosing  regimen.  The trial is designed to enroll
approximately  60  patients  in  the  United  States,   and  will  evaluate  two
formulations of T-20 compared to the formulation presently used in other ongoing
clinical  trials.   All  three   formulations  will  be  given  as  twice  daily
subcutaneous  injections in combination  with oral anti-HIV  agents selected for
each patient on an individualized basis.

     Future T-20 Clinical Trials

     Throughout the remainder of 2001, we expect to initiate additional Phase II
trials.

     T-1249

     We are also  developing  T-1249,  our second drug  candidate for HIV fusion
inhibition,  which has been granted fast track designation by the FDA. T-1249 is
currently in a Phase I clinical trial.

     Phase I - T-1249-101

     In July 1999, we initiated T1249-101,  a Phase I/II clinical trial designed
to assess the safety and  pharmacokinetics  of  T-1249.  T1249-101  enrolled  72
HIV-infected individuals at several sites in the United States, with 61 patients
completing the study.  Three different  daily doses of T-1249 were  administered
alone  and not in  combination  with any  other  anti-HIV  drugs  for 14 days to
HIV-infected  adults by once or twice daily  subcutaneous  injection.  Of the 72
patients  randomized  for the  trial,  nine  withdrew  before  receiving  T-1249
therapy,  and two withdrew  during the course of the  therapy.  For at least two
weeks prior to entering  the study,  these  patients  had not received any other
anti-HIV  drugs.  This trial  protocol  has been  amended  in order to  evaluate
further different daily doses of T-1249 by once daily subcutaneous injection and
is ongoing.


                                       12



     In February  2001,  we  announced  interim  data from  T1249-101.  Patients
received T-1249 via once or twice daily subcutaneous injections alone and not in
combination with any other anti-HIV drugs for 14 days at doses ranging from 6.25
mg per day to 50 mg per day. At entry into the trial, 98%, or 62 of 63, patients
had a clinical history of exposure to a mean number of ten anti-HIV drugs. At 14
days, the median maximum  reduction in viral load reduction from baseline at the
beginning  of the trial ranged from 0.1 log(10) or 20.5% to 1.5 log(10) or 96.8%
across the treatment groups.  Data suggest that T-1249 was well-tolerated over a
14-day period and there were dose-related decreases in HIV viral load.


Risk Factors

     Our business is subject to certain risks and uncertainties. Please read the
"Risk  Factors" and  "Business"  sections of our 2000 Annual Report on Form 10-K
filed with the  Securities  and  Exchange  Commission  on April 2,  2001,  which
highlight some of these risks. If any of these risks materialize,  our business,
financial  condition  and results of operations  could be  materially  adversely
affected.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
        ----------------------------------------------------------

     Our exposure to market risk is primarily in our investment portfolio. We do
not use derivative financial instruments for speculative or trading purposes. We
have an investment  policy that sets minimum  credit  quality  standards for our
investments. The policy also limits the amount of money we can invest in any one
issue,  issuer or type of instrument.  We have not experienced any material loss
in our investment portfolio.

     In July 2000, we entered into a series of call transactions with respect to
our common  stock.  These  transactions  are  described  in detail  under Item 2
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations - Liquidity and Capital Resources."

     The table below presents the carrying value,  which is approximately  equal
to fair  market  value,  and  related  weighted-average  interest  rates for our
investment  portfolio at March 31, 2001.  Substantially  all of our  investments
mature in eighteen months or less.

         (b)  Not applicable.

         (c)  On May 10,  2001,  we completed a private  placement  financing by
              issuing approximately 1.4 million shares of common stock at $33.00
              per  share  to new  and  current  stockholders  for  an  aggregate
              offering  price of  approximately  $46.1 million  (less  estimated
              offering   costs,   including   underwriting    commissions,    of
              approximately  $2.7  million).  Lehman  Brothers,  Inc.  acted  as
              placement  agent  for the  shares  issued in  connection  with the
              private placement  financing.  The registration  statement on Form
              S-3 (File No.  333-31662)  to  register  the  resale of the common
              stock  issued  in this  financing  was filed on May 11,  2001.  An
              exemption from  registration  was claimed pursuant to Section 4(2)
              of the  Securities  Act of  1933,  as  amended,  and  Rule 506 and
              Regulation S promulgated thereunder. Net proceeds of approximately
              $43.4 million from this private  placement  financing will be used
              to fund the clinical  development of our product candidates,  T-20
              and T-1249, to fund increased research and development activities,
              to provide working capital and for general corporate purposes.
