PAIN THERAPEUTICS, INC.
(A DEVELOPMENT STAGE ENTERPRISE)

NOTES TO CONDENSED FINANCIAL STATEMENTS
(UNAUDITED)

NOTE 1. GENERAL

Pain Therapeutics, Inc. is a development stage enterprise and was
incorporated on May 4, 1998. Since our inception in May 1998, we have licensed
proprietary technology from Albert Einstein College of Medicine and have devoted
substantially all of our resources to the development of a new generation of
opioid painkillers with improved clinical benefits, which are based on the
acquired technology. In the course of our development activities, we have
sustained operating losses and expect such losses to continue through the next
several years. We expect our current cash and cash equivalents will be
sufficient to meet our planned working capital and capital expenditure
requirements for at least the next twelve months. There are no assurances that
additional financing will be available on favorable terms, or at all.

Our development activities involve inherent risks. These risks include,
among others, dependence on key personnel and determination of patentability and
protection of our products and processes. In addition, we have product
candidates that have not yet obtained Food and Drug Administration approval.
Successful future operations depend on our ability to obtain approval for and
commercialize these products.

We currently have four opioid painkillers in various stages of Phase II
clinical trials, including our two lead product candidates MorViva(TM) and
OxyTrex(TM). We have completed multiple Phase I and Phase II studies for
MorViva(TM) and two pharmacokinetic and safety studies for OxyTrex(TM) and we
are designing and conducting clinical trials to demonstrate the safety and
efficacy of these two drug candidates. We are developing PTI-701 and PTI-601 on
a very limited basis at the present time.

We have prepared the accompanying unaudited condensed financial statements
in accordance with generally accepted accounting principles for interim
financial information and pursuant to the instruction to Form 10-Q and Article
10 of Regulation S-X. Accordingly, the financial statements do not include all
of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In our opinion, all adjustments,
consisting of normal recurring adjustments, considered necessary for a fair
presentation have been included. Operating results for the three months ended
March 31, 2002 are not necessarily indicative of the results that may be
expected for the year ended December 31, 2002. Certain prior year balances have
been reclassified for comparative purposes.

These unaudited condensed financial statements and notes should be read in
conjunction with the audited financial statements and notes to those financial
statements for the year ended December 31, 2001 included in our Annual Report on
Form 10-K as filed with the Securities and Exchange Commission.

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

NOTE 2. NET LOSS PER SHARE

Basic net loss per share is computed on the basis of the weighted-average
number of shares outstanding for the reporting period. The Company has computed
its weighted-average shares outstanding for all periods presented excluding
those common shares issued and outstanding that remain subject to the Company's
repurchase rights. Diluted net loss per share is computed on the basis of the
weighted-average number of common shares plus dilutive potential common shares
outstanding using the treasury-stock method. Potential dilutive common shares
consist of common shares issued and outstanding subject to the Company's
repurchase rights, outstanding stock options and outstanding warrants. All
potential dilutive common shares

4
were excluded from the calculation of diluted net loss per share because the
representative share increments would be anti-dilutive.

NOTE 3. 1998 STOCK PLAN

In accordance with the provisions of the 1998 Stock Plan, effective January
1, 2002 the number of shares of common stock authorized for issuance under the
1998 Stock Plan was increased from 6,000,000 to 7,000,000 shares.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

This discussion and analysis should be read in conjunction with our
unaudited condensed financial statements and accompanying notes included in this
report and the audited financial statements and notes thereto included in our
Annual Report on Form 10-K for the year ended December 31, 2001 as filed with
the Securities and Exchange Commission. Operating results are not necessarily
indicative of results that may occur in future periods.

The following discussion contains forward-looking statements that are based
upon current expectations that are within the meaning of the Private Securities
Reform Act of 1995. It is the Company's intent that such statements be protected
by the safe harbor created thereby. Forward-looking statements involve risks and
uncertainties and our actual results and the timing of events may differ
significantly from the results discussed in the forward-looking statements.
Examples of such forward-looking statements include, but are not limited to:
statements about future operating losses and anticipated operating and capital
expenditures; statements about the potential benefits of our products;
statements relating to the timing, breadth, status or anticipated results of the
clinical development of our products; statements relating to the protection of
our intellectual property; statements about expected future sources of revenue;
statements about potential competitors or competitive products; statements about
future market acceptance of our products; statements about expenses increasing
substantially or fluctuating; statements about future expectations regarding
trade secrets, technological innovations, licensing agreements and outsourcing
of certain business functions; statements about future non-cash charges related
to option grants; statements about anticipated hiring; statements about the
sufficiency of our current resources to fund our operations over the next twelve
months; statements about increasing cash requirements; statements about future
negative operating cash flows; statements about fluctuations in our operating
results; and statements about development of our internal systems and
infrastructure. Such forward-looking statements involve risks and uncertainties,
including, but not limited to, those risks and uncertainties relating to
difficulties or delays in development, testing, regulatory approval, production
and marketing of the Company's drug candidates, unexpected adverse side effects
or inadequate therapeutic efficacy of the Company's drug candidates that could
slow or prevent product approval (including the risk that current and past
results of clinical trials are not indicative of future results of clinical
trials), the uncertainty of patent protection for the Company's intellectual
property or trade secrets, potential infringement of the intellectual property
rights or trade secrets of third parties and the Company's ability to obtain
additional financing if necessary. In addition such statements are subject to
the risks and uncertainties discussed in the "Risk Factors" section and
elsewhere in this document.

OVERVIEW

Pain Therapeutics, Inc. is developing a new generation of opioid
painkillers with improved clinical benefits. We believe our drugs will offer
enhanced pain relief and reduced tolerance/physical dependence or addiction
potential compared to existing opioid painkillers. We conduct our research and
development programs through a combination of internal and collaborative
programs. Our management relies on arrangements with universities, contract
research organizations and clinical research sites for a significant portion of
our product development efforts.

We currently have four opioid painkillers in various stages of Phase II
clinical trials, including our two lead product candidates, MorViva(TM)and
OxyTrex(TM), and two other product candidates, PTI-701 and PTI-601:

- MorViva(TM) is the brand name for our product previously known as PTI-501
(injectible version) and PTI-555 (oral version) which we are developing
to treat patients with severe pain.

- OxyTrex(TM) is the brand name for our product previously known as PTI-801
which we are developing to treat patients with moderate to severe pain in
a chronic setting.

- PTI-701 is the next generation version of hydrocodone, which we are
developing to treat patients with acute moderate to severe pain.

6
- PTI-601 is the next generation version of tramadol, which we are
developing to treat patients with moderate pain in an acute setting.

Based on the results of multiple Phase I and Phase II studies completed for
MorViva(TM) and two pharmacokinetic and safety studies completed for
OxyTrex(TM), we are designing and conducting clinical trials to demonstrate the
safety and efficacy of these two drug candidates in different clinical settings
of pain. We are currently developing PTI-701 and PTI-601 on a very limited basis
in order to focus our financial resources on MorViva(TM) and OxyTrex(TM). No
significant trials are planned in the near future using PTI-701 or PTI-601.

We have yet to generate any revenues from product sales. We have not been
profitable and, since our inception, we have incurred a cumulative deficit of
approximately $40.7 million through March 31, 2002. These losses have resulted
principally from costs incurred in connection with research and development
activities, including costs of preclinical and clinical trials as well as
clinical supplies associated with our product candidates, salaries and other
personnel related costs, including the amortization of deferred compensation
associated with options granted to employees and non-employees, and general
corporate expenses. Our operating results may fluctuate substantially from
period to period as a result of the timing and enrollment rates of clinical
trials for our product candidates, our need for clinical supplies, as well as
the re-measurement of certain deferred stock compensation.

We expect to incur significant additional operating losses for the next
several years. We also expect to continue to incur significant operating and
capital expenditures and anticipate that our expenses will increase
substantially in the foreseeable future as we:

- continue to undertake preclinical and clinical trials for our product
candidates;

- seek regulatory approvals for our product candidates;

- develop, formulate, manufacture and commercialize our drugs;

- implement additional internal systems and develop new infrastructure;

- acquire or in-license additional products or technologies, or expand the
use of our technology;

- maintain, defend and expand the scope of our intellectual property; and

- hire additional personnel.

Product revenue will depend on our ability to receive regulatory approvals
for, and successfully market, our product candidates. In the event that our
development efforts result in regulatory approval and successful
commercialization of our product candidates, we will generate revenue from
direct sales of our products and/or, if we license our products to future
collaborators, from the receipt of license fees and royalties from licensed
products.

Sources of revenue for the foreseeable future may also include payments
from potential collaborative arrangements, including license fees, funded
research payments, milestone payments and royalties based on revenues received
from products commercialized under such arrangements.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2002 AND 2001

Research and Development

Research and development expense consists of non-cash stock based
compensation (as described below) and other research and development expense.
Other research and development expense consists of drug development work
associated with our product candidates, primarily including costs of preclinical
development, clinical trials, clinical supplies and related formulation and
design costs, research payments to the Albert Einstein College of Medicine and
salaries and other personnel related expenses. Other research and development
expense was $2.7 million for the three months ended March 31, 2002 compared to
$2.5 million for the three months ended March 31, 2001. The period to period
increase of $0.2 million was primarily due to

7
additional staff and increases in salaries and other personnel related costs.
Other research and development expenses are expected to increase significantly
over the next several years as our development efforts are expanded and our
product candidates enter into various stages of clinical trials, and may vary
from period to period due to the timing of these activities.

General and Administrative

General and administrative expense consists of non-cash stock based
compensation (as described below) and other general and administrative expense.
Other general and administrative expense consists primarily of salaries and
other personnel related expenses to support our activities, consulting and
professional services expenses, facilities expenses and other general corporate
expenses. Other general and administrative expenses were $1.3 million for the
three month period ended March 31, 2002 compared to $1.0 million for the three
month period ended March 31, 2001. The period to period increase of $0.3 million
was primarily due to additional staff and increases in salaries and other
personnel related costs and amortization on leasehold improvements. General and
administrative expense may increase in the future in support of increased
research and development or general corporate activities.

Non-Cash Stock Based Compensation

Deferred stock compensation for options granted to employees represents the
difference between the exercise price of the option and the fair value of our
common stock on the date of grant in accordance with Accounting Principles Board
Opinion No. 25 and its related interpretations. Deferred compensation for non-
employees is recorded at the fair value of the options granted in accordance
with Statement of Financial Accounting Standards No. 123 ("SFAS 123") and is
periodically re-measured until the underlying options vest in accordance with
Emerging Issues Task Force No. 96-18 ("EITF 96-18"). The fair value of options
granted to non-employees is estimated using a Black-Scholes option valuation
model. The model considers a number of factors, including the market price and
expected volatility of our common stock at the date of measurement or
re-measurement. The compensation expense related to all grants is being
amortized using the graded vesting method, in accordance with SFAS 123, EITF
96-18 and FASB Interpretation No. 28, over the vesting period of each respective
stock option, generally four years. The graded vesting method results in
expensing approximately 57% of the total award in year one, 26% in year two, 13%
in year three and 4% in year four.

We recognized non-cash stock based compensation expense for options granted
as a component of both research and development expense and general and
administrative expense totaling $0.3 million for the three months ended March
31, 2002 compared to a credit of ($0.3) million for the three months ended March
31, 2001. The change was primarily the result of fluctuations in the market
price of our common stock period to period. There will also continue to be
future non-cash charges for the amortization of deferred compensation related to
options granted to employees and non-employees.

Interest Income

Interest income decreased to $0.3 million for the period ended March 31,
2002 from $1.1 million for the period ended March 31, 2001. The decrease of $0.8
million resulted from declining interest rates and lower average balances of
cash and cash equivalents in the 2002 period.

LIQUIDITY AND CAPITAL RESOURCES

Since inception, we have financed our operations primarily through the
private placement of our preferred stock and the public sale of our common
stock. We intend to continue to use these proceeds to fund research and
development activities, capital expenditures, working capital and other general
corporate purposes. As of March 31, 2002, cash and cash equivalents were $61.4
million. Currently, our cash and cash equivalents are primarily invested in
money market funds.

Net cash used in operating activities was $4.0 million for the period ended
March 31, 2002 compared to $2.0 million in 2001. Cash used in operating
activities related primarily to the funding of net operating losses
8
partially offset by non-cash charges related to the amortization of deferred
stock compensation and changes in operating asset and liability accounts during
the quarter.

Our investing activities used $0.9 million for the three months ended March
31, 2001 and consisted of purchases of property and equipment as well as the
funding of tenant improvements in conjunction with the build-out of new office
space. We had minimal investing expenditures in the current quarter. We expect
to continue making investments in our infrastructure to support our operations.

Our financing activities provided cash of $0.1 million for the period ended
March 31, 2002 and we had minimal financing activities in the period ended March
31, 2001.

We currently lease approximately 10,500 square feet of general office
space. Lease payments under this lease agreement total $1.8 million and
commenced in October 2000 through the ten-year term of the lease. In April 2001
we completed the build-out of tenant improvements and relocated to this facility
and subsequently terminated existing sublease agreements on 6,150 feet of space.

Under the terms of our license agreement with Albert Einstein College of
Medicine, we are required to make milestone payments upon the achievement of
certain regulatory and clinical events. In the aggregate, these success-based
milestones may total up to $4.8 million including amounts due upon receipt of
our first drug approval in the U.S. and in specified foreign countries. We also
must pay Albert Einstein College of Medicine royalties based on a percentage of
net sales of our products. If a product is combined with a drug or other
substance for which we are paying an additional royalty, the royalty rate we pay
to Albert Einstein College of Medicine will be reduced by one-half of the amount
of such additional royalty.

Since our inception we have incurred a cumulative deficit of approximately
$40.7 million, including a net loss of $4.0 million in the period ended March
31, 2002, and we expect to incur significant additional operating losses for the
next several years. Since inception we have used $26.8 million of cash in
operating activities, used $2.7 million of cash in investing activities and
$90.8 million of cash has been provided by financing activities, resulting in
cash and cash equivalents of $61.4 million at March 31, 2002. We expect our cash
requirements to increase in the foreseeable future as we continue to undertake
preclinical and clinical trials for our product candidates; seek regulatory
approvals for our product candidates; develop, formulate, manufacture and
commercialize our drugs; implement additional internal systems and develop new
infrastructure; acquire or in-license additional products or technologies, or
expand the use of our technology; maintain, defend and expand the scope of our
intellectual property; and hire additional personnel. The amount and timing of
cash requirements will depend on regulatory and market acceptance of our
products, if any, and the resources we devote to researching and developing,
formulating, manufacturing, commercializing and supporting our products. We
believe that our current resources should be sufficient to fund our operations
for at least the next twelve months. We may seek additional future funding
through public or private financing within this timeframe, if such funding is
available and on terms acceptable to us.

FACTORS THAT MAY AFFECT OUR FUTURE RESULTS

You should carefully consider the following risk factors and all other
information contained in this Form 10-Q and our Annual Report on Form 10-K for
the year ended December 31, 2001 as filed with the Securities and Exchange
Commission. Risks and uncertainties, in addition to those we describe below,
that are not presently known to us, or that we currently believe are immaterial
may also impair our business operations. If any of the following risks occur,
our business, operating results and financial condition could be seriously
harmed. In addition, the trading price of our common stock could suddenly
decline due to the occurrence of any of these risks.

OUR BRIEF OPERATING HISTORY MAY MAKE IT DIFFICULT FOR YOU TO EVALUATE THE
SUCCESS OF OUR BUSINESS TO DATE AND TO ASSESS ITS FUTURE VIABILITY.

We were founded in May 1998 and we are still in the development stage. Our
operations to date have been limited to organizing and staffing our company,
acquiring, developing and securing our technology and undertaking preclinical
studies and clinical trials. We have not yet demonstrated our ability to obtain

9
regulatory approval, formulate and manufacture product or conduct sales and
marketing activities. Consequently, any predictions you make about our future
success or viability may not be as accurate as they could be if we had a longer
operating history.

WE HAVE A HISTORY OF LOSSES AND EXPECT TO INCUR SUBSTANTIAL LOSSES AND NEGATIVE
OPERATING CASH FLOWS FOR THE FORESEEABLE FUTURE.

We have incurred net losses each year since our inception. As a result of
ongoing operating losses, we had an accumulated deficit of $40.7 million as of
March 31, 2002. We are not currently profitable. Even if we succeed in
developing and commercializing one or more of our drugs, we expect to incur
substantial losses for the foreseeable future and may never become profitable.
We also expect to continue to incur significant operating and capital
expenditures and anticipate that our expenses will increase substantially in the
foreseeable future as we:

- continue to undertake preclinical and clinical trials for our product
candidates;

- seek regulatory approvals for our product candidates;

- develop, formulate, manufacture and commercialize our drugs;

- implement additional internal systems and develop new infrastructure;

- acquire or in-license additional products or technologies, or expand the
use of our technology;

- maintain, defend and expand the scope of our intellectual property; and

- hire additional personnel.

We also expect to experience negative cash flow for the foreseeable future
as we fund our operating losses and capital expenditures. As a result, we will
need to generate significant revenues to achieve and maintain profitability. If
we cannot successfully develop and commercialize our products, we will not be
able to generate such revenues or achieve profitability in the future. Our
failure to achieve or maintain profitability could negatively impact the market
price of our common stock.

IF WE CANNOT RAISE ADDITIONAL CAPITAL ON ACCEPTABLE TERMS, WE MAY BE UNABLE TO
COMPLETE PLANNED ADDITIONAL CLINICAL TRIALS OF ANY OR SOME OF OUR PRODUCT
CANDIDATES.

Until we receive regulatory approval and commercialize one or more of our
products, we will have to fund all of our operations and capital expenditures
from cash on hand. We expect that our current cash and cash equivalents on hand
will be sufficient to meet our working capital and capital expenditure needs for
at least the next twelve months. However, if we experience unanticipated cash
requirements, we may need to raise additional funds much sooner and additional
financing may not be available on favorable terms, if at all. Even if we succeed
in selling additional equity securities to raise funds, our existing
stockholders' ownership percentage would be reduced and new investors may demand
rights, preferences or privileges senior to those of existing stockholders. If
we do not succeed in raising additional funds, we may be unable to complete
planned clinical trials or obtain FDA approval of our product candidates, and we
could be forced to discontinue product development, reduce sales and marketing
efforts and forego attractive business opportunities.

IF OUTSIDE RESEARCHERS FAIL TO DEVOTE SUFFICIENT TIME AND RESOURCES TO OUR DRUG
DEVELOPMENT PROGRAMS, OR IF THEIR PERFORMANCE IS SUBSTANDARD, OUR REGULATORY
SUBMISSIONS AND OUR PRODUCT INTRODUCTIONS MAY BE DELAYED.

We depend on independent investigators and collaborators, such as
universities and medical institutions, to conduct our clinical trials under
agreements with us. These collaborators are not our employees and we cannot
control the amount or timing of resources that they devote to our programs.
These investigators may not assign as great a priority to our programs or pursue
them as diligently as we would if we were undertaking such programs ourselves.
If outside collaborators fail to devote sufficient time and resources to our
drug development programs, or if their performance is substandard, the approval
of our regulatory submissions and

10
our introductions of new drugs will be delayed. These collaborators may also
have relationships with other commercial entities, some of whom may compete with
us. If outside collaborators assist our competitors at our expense, our
competitive position could be harmed.

IF WE ARE UNABLE TO DESIGN, CONDUCT AND COMPLETE CLINICAL TRIALS SUCCESSFULLY,
WE WILL NOT BE ABLE TO SUBMIT A NEW DRUG APPLICATION TO THE FDA.

In order to obtain FDA approval of any of our product candidates, we must
submit to the FDA a New Drug Application, or NDA, which demonstrates that the
product candidate is safe for humans and effective for its intended use. This
demonstration requires significant research and animal tests, which are referred
to as preclinical studies, as well as human tests, which are referred to as
clinical trials. We have four product candidates in various stages of clinical
trials including MorViva(TM) (previously known as PTI-501 (injectible version)
and PTI-555 (oral version)), OxyTrex(TM)(previously known as PTI-801), PTI-701
and PTI-601. We have completed multiple Phase I and Phase II studies for
MorViva(TM) and two pharmacokinetic and safety studies for OxyTrex(TM), and we
are designing and conducting clinical trials to demonstrate the safety and
efficacy of these two drug candidates in different clinical settings of pain. No
significant trials are planned in the near future for PTI-701 or PTI-601. We
will have to commit substantial time and additional resources to conducting
further preclinical and clinical studies in several types of pain before we can
submit NDAs with respect to any of these product candidates. Our other product
candidates are at a much earlier stage of development and will require extensive
preclinical and clinical testing before we can make any decision to proceed with
their clinical development.

Human clinical trials are very expensive and difficult to design and
implement, in part because they are subject to rigorous requirements. The
clinical trial process is also time consuming. We estimate that clinical trials
of our leading product candidates will take a minimum of three years or more to
complete and may take longer. If we or the FDA believe the participating
patients are being exposed to unacceptable health risks, we would have to
suspend our clinical trials. Furthermore, failure can occur at any stage of the
trials, and we could encounter problems that cause us to abandon clinical trials
or to repeat clinical studies.

Even if our clinical trials are completed as planned, their results may not
support our product claims. Success in pre-clinical testing and early clinical
trials does not ensure that later clinical trials will be successful, and the
results of later clinical trials may not replicate the results of prior clinical
trials and pre-clinical testing. The clinical trial process may fail to
demonstrate that our product candidates are safe for humans and effective for
indicated uses. Such failure would cause us to abandon a product candidate and
may delay development of other product candidates.

IF WE FAIL TO OBTAIN THE NECESSARY REGULATORY APPROVALS, WE WILL NOT BE ALLOWED
TO COMMERCIALIZE OUR DRUGS AND WILL NOT GENERATE PRODUCT REVENUES.

Satisfaction of all regulatory requirements typically takes many years, is
dependent upon the type, complexity and novelty of the product candidate and
requires the expenditure of substantial resources for research and development
and testing. Our research and clinical approaches may not lead to drugs that the
FDA considers safe for humans and effective for indicated uses. The FDA may
require us to conduct additional clinical testing or to commit to perform
post-marketing studies, in which cases we would have to expend additional
unanticipated time and resources. The approval process may also be delayed by
changes in government regulation, future legislation or administrative action or
changes in FDA policy that occur prior to or during our regulatory review.
Delays in obtaining regulatory approvals may:

- delay commercialization of, and product revenues from, our product
candidates;

- impose costly procedures on us; and

- diminish any competitive advantages that we may otherwise enjoy.

Even if we comply with all FDA requests, the FDA may ultimately deny one or
more of our NDAs, and we may never obtain regulatory approval for any of our
product candidates. If we fail to achieve regulatory approval of any of our
leading product candidates we will have fewer saleable products and
corresponding
11
product revenues. Even if we receive regulatory approval of our products, such
approval may involve limitations on the indicated uses or marketing claims we
may make for our products. Further, later discovery of previously unknown
problems could result in additional regulatory restrictions, including
withdrawal of products.

In foreign jurisdictions, we must receive marketing authorizations from the
appropriate regulatory authorities before we can commercialize our drugs.
Foreign regulatory approval processes generally include all of the requirements
and risks associated with the FDA approval procedures described above.

IF PHYSICIANS AND PATIENTS DO NOT ACCEPT AND USE OUR DRUGS, WE WILL NOT ACHIEVE
SUFFICIENT PRODUCT REVENUES AND OUR BUSINESS WILL SUFFER.

Even if the FDA approves our drugs, physicians and patients may not accept
and use them. Acceptance and use of our drugs will depend on a number of factors
including:

- perceptions by members of the healthcare community, including physicians,
about the safety and effectiveness of our drugs;

- cost-effectiveness of our drugs relative to competing products;

- availability of reimbursement for our products from government or
healthcare payers; and

- effectiveness of marketing and distribution efforts by us and our
licensees and distributors, if any.

Because we expect to rely on sales generated by our current lead product
candidates for substantially all of our product revenues for the foreseeable
future, the failure of any of these drugs to find market acceptance would harm
our business and could require us to seek additional financing.

IF THIRD-PARTY MANUFACTURERS OF OUR PRODUCT CANDIDATES FAIL TO DEVOTE SUFFICIENT
TIME AND RESOURCES TO OUR CONCERNS, OR IF THEIR PERFORMANCE IS SUBSTANDARD, OUR
CLINICAL TRIALS AND PRODUCT INTRODUCTIONS MAY BE DELAYED AND OUR COSTS MAY RISE.

We have no manufacturing facilities and have limited experience in drug
product development and commercial manufacturing. We lack the resources and
expertise to formulate, manufacture or to test the technical performance of our
product candidates. We currently rely on a limited number of experienced
personnel and a small number of contract manufacturers and other vendors to
formulate, test, supply, store and distribute drug supplies for our clinical
trials. Our reliance on a limited number of vendors exposes us to the following
risks, any of which could delay our clinical trials, and consequently delay FDA
approval of our product candidates and commercialization of our products, result
in higher costs or deprive us of potential product revenues:

- Contract commercial manufacturers, their sub-contractors or other third
parties we rely on, may encounter difficulties in achieving the volume of
production needed to satisfy clinical needs or commercial demand, may
experience technical issues that impact quality, and may experience
shortages of qualified personnel to adequately staff production
operations. The use of alternate manufacturers may be difficult because
the number of potential manufacturers that have the necessary
governmental licenses to produce narcotic products is limited.
Additionally, FDA must approve any alternative manufacturer of our
product before we may use the alternative manufacturer to produce our
clinical supplies. It may be difficult or impossible for us to find a
replacement manufacturer on acceptable terms quickly, or at all. Our
contract manufacturers and vendors may not perform as agreed or may not
remain in the contract manufacturing business for the time required to
successfully produce, store and distribute our products.

- Approved third party commercial drug manufacturers may subsequently be
stopped from producing, storing, shipping or testing our drug products
due to their non-compliance with federal, state or local regulations.
Drug manufacturers are subject to ongoing periodic unannounced inspection
by the FDA, the DEA and corresponding state agencies to ensure strict
compliance with good manufacturing

12
practice and other government regulations and corresponding foreign
standards. We do not have control over third-party manufacturers'
compliance with these regulations and standards.

- If any third-party manufacturer makes improvements in the manufacturing
process for our products, we may not own, or may have to share, the
intellectual property rights to such innovation.

IF WE ARE UNABLE TO DEVELOP OUR OWN SALES, MARKETING AND DISTRIBUTION
CAPABILITIES, OR IF WE ARE NOT SUCCESSFUL IN CONTRACTING WITH THIRD PARTIES FOR
THESE SERVICES ON FAVORABLE TERMS, OUR PRODUCT REVENUES COULD BE DISAPPOINTING.

We currently have no sales, marketing or distribution capabilities. In
order to commercialize our products, if any are approved by the FDA, we will
either have to develop such capabilities internally or collaborate with third
parties who can perform these services for us. If we decide to commercialize any
of our drugs ourselves, we may not be able to hire the necessary experienced
personnel and build sales, marketing and distribution operations which are
capable of successfully launching new drugs and generating sufficient product
revenues. In addition, establishing such operations will take time and involve
significant expense. On the other hand, if we decide to enter into co-promotion
or other licensing arrangements with third parties, we may be unable to locate
acceptable collaborators because the significant number of recent business
combinations among pharmaceutical companies has resulted in a reduced number of
potential future collaborators. Even if we are able to identify one or more
acceptable collaborators, we may not be able to enter into any collaborative
arrangements on favorable terms, or at all. In addition, due to the nature of
the market for pain management products, it may be necessary for us to license
all or substantially all of our product candidates to a single collaborator,
thereby eliminating our opportunity to commercialize other pain management
products independently. If we enter into any collaborative arrangements, our
product revenues are likely to be lower than if we marketed and sold our
products ourselves. In addition, any revenues we receive would depend upon the
efforts of our collaborators which may not be adequate due to lack of attention
or resource commitments, management turnover, change of strategic focus, further
business combinations or other factors outside of our control. Depending upon
the terms of our collaboration, the remedies we have against an under-performing
collaborator may be limited. If we were to terminate the relationship, it may be
difficult or impossible to find a replacement collaborator on acceptable terms,
or at all.

IF WE CANNOT COMPETE SUCCESSFULLY FOR MARKET SHARE AGAINST OTHER DRUG COMPANIES,
WE MAY NOT ACHIEVE SUFFICIENT PRODUCT REVENUES AND OUR BUSINESS WILL SUFFER.

The market for our product candidates is characterized by intense
competition and rapid technological advances. If our products receive FDA
approval, they will compete with a number of existing and future drugs and
therapies developed, manufactured and marketed by others. Existing or future
competing products may provide greater therapeutic convenience or clinical or
other benefits for a specific indication than our products, or may offer
comparable performance at a lower cost. If our products are unable to capture
and maintain market share, we may not achieve sufficient product revenues and
our business will suffer.

We will compete for market share against fully integrated pharmaceutical
companies or other companies that are collaborating with larger pharmaceutical
companies, academic institutions, government agencies and other public and
private research organizations. Many of these competitors have opioid
painkillers already approved or in development. In addition, many of these
competitors, either alone or together with their collaborative partners, operate
larger research and development programs and have substantially greater
financial resources than we do, as well as significantly greater experience in:

- developing drugs;

- undertaking preclinical testing and human clinical trials;

- obtaining FDA and other regulatory approvals of drugs;

- formulating and manufacturing drugs; and

- launching, marketing, distributing and selling drugs.

13
DEVELOPMENTS BY COMPETITORS MAY RENDER OUR PRODUCTS OR TECHNOLOGIES OBSOLETE OR
NON-COMPETITIVE.

Alternative technologies and products are being developed to improve or
replace the use of opioids for pain management, several of which are in clinical
trials or are awaiting approval from the FDA. Such alternatives include Elan's
Ziconotide(TM) and Endo Pharmaceuticals' MorphiDex(R). In addition, companies
that sell generic opioid drugs represent substantial competition. Many of these
organizations competing with us have substantially greater capital resources,
larger research and development staffs and facilities, greater experience in
drug development and in obtaining regulatory approvals and greater manufacturing
and marketing capabilities than we do. These organizations also compete with us
to attract qualified personnel, parties for acquisitions, joint ventures or
other collaborations.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY OUR COMPETITORS COULD
DEVELOP AND MARKET PRODUCTS WITH SIMILAR FEATURES THAT MAY REDUCE DEMAND FOR OUR
PRODUCTS.

Our success, competitive position and potential future revenues will depend
in part on our ability to protect our intellectual property. If either we or
Albert Einstein College of Medicine fails to file, prosecute or maintain any of
our existing patents, our competitors could market products that contain
features and clinical benefits similar to those of our products, and demand for
our products could decline as a result. We intend to file additional patent
applications relating to our technology, products and processes. We may direct
Albert Einstein College of Medicine to file additional patent applications
relating to the licensed technology or we may do so ourselves. However, our
competitors may challenge, invalidate or circumvent any of our current or future
patents. These patents may also fail to provide us with meaningful competitive
advantages.

We expect that we will rely upon trade secrets, know-how, continuing
technological innovations and licensing opportunities to develop and maintain
our competitive position. Others may independently develop substantially
equivalent proprietary information or be issued patents that may prevent the
sale of our products or know-how or require us to license such information and
pay significant fees or royalties in order to produce our products. Moreover,
our technology could infringe upon claims of patents owned by others. If we were
found to be infringing on a patent held by another, we might have to seek a
license to use the patented technology. In that case, we might not be able to
obtain such a license on terms acceptable to us, or at all. If a legal action
were to be brought against us or our licensors, we could incur substantial
defense costs, and any such action might not be resolved in our favor. If such a
dispute were to be resolved against us, we could have to pay the other party
large sums of money and our use of our technology and the testing, manufacture,
marketing or sale of one or more of our proposed products could be restricted or
prohibited.

COMPETITION FOR QUALIFIED PERSONNEL IN THE PHARMACEUTICAL INDUSTRY IS INTENSE,
AND IF WE ARE NOT SUCCESSFUL IN ATTRACTING AND RETAINING QUALIFIED PERSONNEL, WE
COULD EXPERIENCE DELAYS IN COMPLETING NECESSARY CLINICAL TRIALS AND THE
REGULATORY APPROVAL PROCESS OR IN FORMULATING, MANUFACTURING, MARKETING AND
SELLING OUR POTENTIAL PRODUCTS.

We will need to hire additional qualified personnel with expertise in
clinical research, preclinical testing, government regulation, formulation and
manufacturing and sales and marketing. We compete for qualified individuals with
numerous biopharmaceutical companies, universities and other research
institutions. Competition for such individuals, particularly in the San
Francisco Bay area, is intense, and our search for such personnel may not be
successful. Attracting and retaining qualified personnel will be critical to our
success.

THE DEA LIMITS THE AVAILABILITY OF THE ACTIVE INGREDIENTS IN OUR CURRENT PRODUCT
CANDIDATES AND, AS A RESULT, OUR QUOTA MAY NOT BE SUFFICIENT TO COMPLETE
CLINICAL TRIALS, MEET COMMERCIAL DEMAND OR MAY RESULT IN CLINICAL DELAYS.

The DEA regulates chemical compounds as Schedule I, II, III, IV or V
substances, with Schedule I substances considered to present the highest risk of
substance abuse and Schedule V substances the lowest risk. The active
ingredients in our current product candidates, including morphine, hydrocodone
and oxycodone, are listed by the DEA as Schedule II or III substances under the
Controlled Substances Act of 1970. Consequently, their manufacture, shipment,
storage, sale and use are subject to a high degree of regulation. For example,
all Schedule II drug prescriptions must be signed by a physician, physically
presented
14
to a pharmacist and may not be refilled without a new prescription. Furthermore,
the amount of Schedule II substances we can obtain for clinical trials and
commercial distribution is limited by the DEA and our quota may not be
sufficient to complete clinical trials or meet commercial demand. There is a
risk that DEA regulations may interfere with the supply of the drugs used in our
clinical trials, and in the future, our ability to produce and distribute our
products in the volume needed to meet commercial demand.

WE MAY INCUR SUBSTANTIAL LIABILITIES AND MAY BE REQUIRED TO LIMIT TESTING OF OUR
PRODUCTS IN RESPONSE TO PRODUCT LIABILITY LAWSUITS.

The risk of product liability is inherent in the testing of medical
products. If we cannot successfully defend ourselves against product liability
claims, we may incur substantial liabilities or be required to limit or
terminate testing of one or more of our products. Our inability to obtain
sufficient product liability insurance at an acceptable cost to protect against
potential product liability claims could prevent or inhibit the
commercialization of our products. We currently carry clinical trial insurance
but do not carry product liability insurance. We may not be able to obtain such
insurance at a reasonable cost, if at all. If our agreements with any future
corporate collaborators entitle us to indemnification against product liability
losses, such indemnification may not be available or adequate should any claim
arise.

OUR ABILITY TO GENERATE PRODUCT REVENUES WILL BE DIMINISHED IF WE FAIL TO OBTAIN
ACCEPTABLE PRICES OR AN ADEQUATE LEVEL OF REIMBURSEMENT FOR OUR PRODUCTS FROM
HEALTHCARE PAYERS.

Our ability to commercialize our drugs, alone or with collaborators, will
depend in part on the extent to which reimbursement will be available from:

- government and health administration authorities;

- private health maintenance organizations and health insurers; and

- other healthcare payers.

Significant uncertainty exists as to the reimbursement status of newly
approved healthcare products. Healthcare payers, including Medicare, health
maintenance organizations (HMO's) and managed care organizations (MCO's), are
challenging the prices charged for medical products and services and/or are
seeking pharmacoeconomic data to justify formulary acceptance and reimbursement
practices. Government and other healthcare payers increasingly are attempting to
contain healthcare costs by limiting both coverage and the level of
reimbursement for drugs, and by refusing, in some cases, to provide coverage for
uses of approved products for disease indications for which the FDA has or has
not granted labeling approval. Third-party insurance coverage may not be
available to patients for any products we discover and develop, alone or with
collaborators. If government and other healthcare payers do not provide adequate
coverage and reimbursement levels for our products, market acceptance of them
could be limited.

OUR STOCK PRICE HAS BEEN VOLATILE AND COULD EXPERIENCE A SUDDEN DECLINE IN
VALUE.

Our common stock has experienced significant price and volume fluctuations
and may continue to experience volatility in the future. You may not be able to
sell your shares quickly or at the market price if trading in our stock is not
active or the volume is low. The following factors, in addition to general
market volatility and other risk factors described in this section, may have a
significant impact on the market price of our common stock:

- announcements of technological innovations or new commercial products by
us or others;

- results of our preclinical and clinical trials;

- developments in patent or other proprietary rights;

- publicity regarding actual or potential medical results relating to
products under developments by us or others;

- comments by securities analysts;
15
- future sales of our common stock by existing stockholders;

- regulatory developments;

- litigation or threats of litigation;

- economic and other external factors or other disaster or crises;

- the departure of any of our officers, directors or key employees;

- period-to-period fluctuations in financial results; and

- limited daily trading volume

OUR SHARE OWNERSHIP IS CONCENTRATED, AND OUR OFFICERS, DIRECTORS AND PRINCIPAL
STOCKHOLDERS CAN EXERT SIGNIFICANT CONTROL OVER MATTERS REQUIRING STOCKHOLDER
APPROVAL.

Due to their combined stock holdings, our officers, directors and principal
shareholders (shareholders holding greater than 5% of our common stock) acting
collectively may have the ability to exercise significant influence over matters
requiring shareholder approval including the election of directors and approval
of significant corporate transactions. In addition, this concentration of
ownership may delay or prevent a change in control of the Company and may make
some transactions more difficult or impossible to complete without the support
of these shareholders.

OUR OPERATING RESULTS MAY FLUCTUATE FROM QUARTER TO QUARTER AND THIS FLUCTUATION
MAY CAUSE OUR STOCK PRICE TO DECLINE.

Our quarterly operating results have fluctuated in the past and are likely
to fluctuate in the future. Factors contributing to these fluctuations include,
among other items, the timing and enrollment rates of clinical trials for our
product candidates, our need for clinical supplies and the re-measurement of
certain deferred stock compensation. Thus, quarter to quarter comparisons of our
operating results are not indicative of what we might expect in the future. As a
result, in some future quarters our operating results may not meet the
expectations of securities analysts and investors which could result in a
decline in the price of our stock.

FUTURE SALES OF OUR COMMON STOCK MAY IMPACT THE PRICE OF OUR COMMON STOCK.

Additional equity financings or other share issuances by us could adversely
affect the market price of our common stock. Additionally, sales by existing
shareholders of a large number of shares of our common stock in the public
market or the perception that additional sales could occur could cause the price
of our common stock to decline and may impair our ability to raise capital in
the future.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve principal
while at the same time maximizing the income we receive from our investments
without significantly increasing risk. Some of the securities that we invest in
may be subject to market risk. This means that a change in prevailing interest
rates may cause the principal amount of the investment to fluctuate. For
example, if we hold a security that was issued with a fixed interest rate at the
then-prevailing rate and the prevailing interest rate later rises, the principal
amount of our investment will probably decline. To minimize this risk in the
future, we intend to maintain our portfolio of cash equivalents and short-term
investments in a variety of securities, including commercial paper, government
and non-government debt securities and/or money market funds that invest in such
securities. In general, money market funds are not subject to market risk
because the interest paid on such funds fluctuates with the prevailing interest
rate. We had no holdings of derivative financial or commodity instruments, and
as of March 31, 2002 all of our cash and cash equivalents were in money market
and checking funds with variable, market rates of interest.
