have been prepared in accordance with U.S. generally accepted accounting
principles for interim financial information and pursuant to the instructions
to Form&nbsp;10-Q and Article&nbsp;10 of Regulation S-X. Accordingly, they do
not include all of the information and notes required by generally accepted
accounting principles for complete financial statements. These unaudited
condensed financial statements include all normal and recurring adjustments
that we believe are necessary to fairly state our financial position and the
results of our operations and cash flows. Interim-period results are not
necessarily indicative of results of operations or cash flows for a full-year.
The balance sheet at December&nbsp;31, 2007 has been derived from audited
financial statements at that date, but does not include all disclosures
required by U.S. generally accepted accounting principles for complete
financial statements. Because all of the disclosures required by U.S. generally
accepted accounting principles for complete financial statements are not
included herein, these interim unaudited condensed financial statements and the
notes accompanying them should be read in conjunction with our audited
financial statements and the notes thereto included in our Annual Report on Form&nbsp;10-K
for the year ended December&nbsp;31, 2007.</font></p>

assumptions that we believe to be reasonable under the circumstances. Actual
results could differ from these estimates.</font></p>

for Collaborative Arrangements,&#148; or EITF 07-1. EITF 07-1 defines collaborative
arrangements and establishes reporting requirements for transactions between
participants in a collaborative arrangement and between participants in the
arrangement and third parties. EITF 07-1 is effective for financial statements
issued for fiscal years beginning after December&nbsp;15, 2008 and will be
applied retrospectively to all prior period presented for all collaborative

third parties, and amortize them over the period that the research and
development activities are performed or the services are provided, subject to
an assessment of recoverability. EITF 07-3 is effective for new contracts
entered into during fiscal years beginning after December&nbsp;15, 2007,

Fair Value Option for Financial Assets and Financial Liabilities - including an
amendment of FASB Statement No.&nbsp;115.&#148; SFAS No.&nbsp;159 permits entities
to choose to measure financial instruments and certain other items at fair
value. Entities that elect the fair value option will report unrealized gains
and losses in earnings at each subsequent reporting date. The fair value option
may be elected on an instrument-by-instrument basis, with few exceptions. SFAS No.&nbsp;159
also establishes presentation and disclosure requirements to facilitate
comparisons between companies that choose different measurement attributes for
similar assets and liabilities. SFAS No.&nbsp;159 is effective for fiscal years
beginning after November&nbsp;15, 2007. We elected not to adopt the fair value
option permitted by SFAS No.&nbsp;159 at this time.</font></p>

SFAS No.&nbsp;123(R), the fair value of each option award is estimated on the

option awards into three homogenous groups, officers and directors, all other

- - We estimated volatility using the historical share price performance over the
expected life of the option up to the point where we have historical market
data. We also considered other factors, such as implied volatility, our current
clinical trials and other company activities that may affect the volatility of
our stock in the future. We determined that at this time historical volatility
is more indicative of our expected future stock performance.</p>

term - We worked with various historical data to determine the most applicable
expected term for each option group. These data included: (1)&nbsp;for options
exercised, term of the options from option grant date to exercise date; (2)&nbsp;for
options cancelled, term of the options from grant date to cancellation date,
excluding unvested option forfeitures; and (3)&nbsp;for options which remained
outstanding at the balance sheet date, term of the options from grant date to
the end of the reporting period, and the estimated remaining term of the
options. The consideration and calculation of the above data gave us reasonable
estimates of the expected term for each option group. We also considered the
vesting schedules of the options granted and factors surrounding exercise
behavior of the option groups, our current market price and company activity
that may affect our market price. In addition, we also considered the vesting
schedules of the options, the optionee type (i.e., officers and directors, all
other employees and consultants) and other factors that may affect the expected
term of the option. For options granted to consultants, we use the contractual
term of the option, which is generally ten years, for the initial valuation of
the option and the remaining contractual term of the option for the succeeding
periods.</p>

exercise prices are set at not less than the closing price of our common stock

at varying dates and generally expire ten years from the date of grant. We
granted options to purchase 1,528,180 shares of common stock during the nine

value of $18.03 per share. We granted options to purchase 1,032,843 shares of
common stock during the nine months ended September&nbsp;30, 2007, with a
grant-date weighted average fair value of $6.96 per share.&#160; As of September&nbsp;30, 2008, there was
approximately $16.1 million of total unrecognized stock-based compensation
cost, net of estimated forfeitures, related to unvested options granted under
our stock option plans. At September&nbsp;30, 2008, 4,458,954 shares of common

value of awards granted under our ESPP is estimated on the date of grant using
the Black-Scholes option pricing model, which uses the weighted-average
assumptions set forth in the table on the next page. Our ESPP provides for a
twenty-four month offering period comprised of four six-month purchase periods
with a look-back option. A look-back option is a provision in our ESPP under
which eligible employees can purchase shares of our common stock at a price per
share equal to the lesser of 85% of the fair market value on the first day of
the offering period or 85% of the fair market value on the purchase date.</font></p>

plan also includes a feature that provides for a new offering period to begin
when the fair market value of our common stock on any purchase date during an
offering </font>period falls below the fair market value of our common
stock on the first day of such offering period. This feature is called a &#147;reset.&#148;
We had a &#147;reset&#148; for a new twenty-four month offering period starting on July&nbsp;1,
2008 because the fair market value of our stock on June&nbsp;30, 2008 was lower
than the fair market value of our stock on January&nbsp;2, 2008, the first day
of the offering period. We applied modification accounting in accordance with
SFAS 123(R)&nbsp;to determine the incremental fair value associated with this
ESPP &#147;reset&#148; and recognized the related stock-based compensation expense
according to the FASB Technical Bulletin, or FTB, No.&nbsp;97-1, &#147;Accounting
under Statement 123 for Certain Employee Stock Purchase Plans with a Look-back
Option.&#148; The total incremental fair value for this ESPP &#147;reset&#148; was $849,155,
which will be recognized over the new twenty-four month offering period.</p>

under the ESPP and 38,160 shares were purchased under the ESPP during the nine

weighted-average assumptions related to our ESPP for the nine months ended September&nbsp;30,
2008 and 2007. Expected volatilities for our ESPP are based on the historical
volatility of our stock. Expected term represents the weighted average of the
purchase periods within the offering period. The risk-free interest rate for
periods within the expected term is based on U.S. Treasury constant maturity
rates. There have been no significant changes in the assumptions before and
after the &#147;reset&#148; of our ESPP plan.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Revenue related to collaborative research with our corporate
collaborators is recognized as research services are performed over the related
development funding periods for each contract. Under these agreements, we are
required to perform research and development activities as specified in the
applicable agreement. The payments received are not refundable and are
generally based on a contractual cost per full-time equivalent employee working
on the project. Research and development expenses under the collaborative
research agreements, except for the Merck collaboration signed in November&nbsp;2004
related to ubiquitin ligases, approximate or exceed the revenue recognized
under such agreements over the term of the respective agreements. For the Merck
collaboration, we recognized a pro-rata portion of the invoiced amounts for
funding of our research scientists based on the headcount dedicated to the
project for the quarter. When the research portion of the collaboration ended
in May&nbsp;2007, we recognized the full amount of the deferred revenue related
to the contract because we had no further obligations. It is our policy to
recognize revenue based on our level of effort expended, and that revenue
recognized will not exceed amounts billable under the arrangement.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Fair value is defined as the price at which an asset
could be exchanged or a liability transferred in a transaction between
knowledgeable, willing parties in the principal or most advantageous market for
the asset or liability. Where available, fair value is based on observable
market prices or parameters or derived from such prices or parameters. Where
observable prices or parameters are not available, valuation models are
applied.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Financial
assets recorded at fair value in the Condensed Financial Statements are
categorized based upon the level of judgment associated with the inputs used to
measure their fair value. Hierarchical levels, defined by SFAS 157 and directly
related to the amount of subjectivity associated with the inputs to fair
valuation of these assets and liabilities, are as follows:</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt .25in;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Level 1 &#151; Inputs are unadjusted, quoted prices in active
markets for identical assets at the reporting date.&#160; Active markets are those in which
transactions for the asset or liability occur in sufficient frequency and
volume to provide pricing information on an ongoing basis.</font></p>

<p style="margin:0in 0in .0001pt .25in;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The fair valued assets we hold that are generally included

<p style="margin:0in 0in .0001pt .25in;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Level 2 &#151; Inputs are other than quoted prices included in
Level 1, which are either directly or indirectly observable for the asset or
liability through correlation with market data at the reporting date and for
the duration of the instrument&#146;s anticipated life.</font></p>

<p style="margin:0in 0in .0001pt .25in;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The fair valued assets we hold that are generally included
in this category were government-sponsored enterprise securities, U. S.
Treasury bills, corporate bonds and commercial paper where fair value is based
on valuation methodologies such as models using observable market inputs, such
as benchmark yields, reported trades, broker/dealer quotes, bids, offers and
other reference data.</font></p>

or no market activity and that are significant to the fair value of the assets
or liabilities and which reflect management&#146;s best estimate of what market
participants would use in pricing the asset or liability at the reporting date.
Consideration is given to the risk inherent in the valuation technique and the
risk inherent in the inputs to the model.</font></p>

we obtained a new equipment lease line with a borrowing capability of $1.5
million.&#160; Our borrowing capacity under
this equipment lease line was increased to $3.2 million in July&nbsp;2008. We
have the ability to draw down on this line until the end of 2008.&#160; The repayment period will be for three years
beginning on the date of each draw down, with the interest rate on the line
fixed at each draw down. Each draw down has a bargain purchase buyout provision
of $1. During the nine months ended September&nbsp;30, 2008, we drew down
approximately $1.4 million, which is included in our capital lease obligation
on our balance sheet.&#160; As of September&nbsp;30,
2008, approximately $1.8 million of the equipment lease line remained
available.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have reviewed the condensed
balance sheet of Rigel Pharmaceuticals,&nbsp;Inc. as of September&nbsp;30,
2008, and the related condensed statements of operations for the three and
nine-month periods ended September&nbsp;30, 2008 and 2007, and the condensed
statements of cash flows for the nine-month periods ended September&nbsp;30,
2008 and 2007. These financial statements are the responsibility of the Company&#146;s
management.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We conducted our review in
accordance with the standards of the Public Company Accounting Oversight Board
(United States). A review of interim financial information consists principally
of applying analytical procedures and making inquiries of persons responsible
for financial and accounting matters. It is substantially less in scope than an
audit conducted in accordance with the standards of the Public Company
Accounting Oversight Board, the objective of which is the expression of an
opinion regarding the financial statements taken as a whole. Accordingly, we do
not express such an opinion.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Based on our review, we are not
aware of any material modifications that should be made to the condensed
interim financial statements referred to above for them to be in conformity
with U.S. generally accepted accounting principles.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have previously audited, in
accordance with the standards of the Public Company Accounting Oversight Board
(United States), the balance sheet of Rigel Pharmaceuticals,&nbsp;Inc. as of December&nbsp;31,
2007, and the related statements of operations, stockholders&#146; equity, and cash
flows for the year then ended (not presented herein) and in our report dated March&nbsp;6,
2008, we expressed an unqualified opinion on those financial statements and
included an explanatory paragraph referencing Rigel Pharmaceuticals,&nbsp;Inc.&#146;s
change in method of accounting for share-based compensation as of January&nbsp;1,
2006 and Note 1 to the financial statements.&#160;
In our opinion, the information set forth in the accompanying condensed
balance sheet as of December&nbsp;31, 2007, is fairly stated, in all material
respects, in relation to the balance sheet from which it has been derived.</font></p>

clinically meaningful adverse events noted in the clinical trial included
dose-related neutropenia, mild elevations of liver function tests and
gastrointestinal side effects. Dose reduction (to one-half the assigned dose by
taking the drug once per day) was pre-specified in the protocol and contingent
on neutrophil counts and/or liver function tests.&#160; Notably, a vast majority of the patients who
had their doses reduced successfully completed the clinical trial with minimal

<p style="margin:0in 0in .0001pt 35.0pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In June&nbsp;2008, we announced the
commencement of two concurrent Phase 2b clinical trials of R788 in RA patients
at a number of clinical research centers throughout the United States, Latin
America, and Europe to evaluate the efficacy of R788 compared to placebo in
distinct RA patient groups.&#160; The first
Phase 2b clinical trial (TASKi 2) is evaluating RA patients receiving 100 mg of
R788 PO bid (orally, twice daily) or 150 mg of R788 PO qd (orally, once daily),
compared with those receiving placebo, in a multi-center, randomized, double
blind, placebo controlled, parallel dose study of R788 in patients who have
failed to respond to methotrexate. The second Phase 2b clinical trial (TASKi 3)
is evaluating a group of RA patients receiving 100 mg of R788 PO bid, compared
with a group receiving placebo, in a multi-center, randomized, double blind,
placebo controlled, parallel dose study of R788 in patients who have failed at
least one marketed biologic agent. The class of biologic agents generally
includes anti-tumor necrosis factor injectables commonly used to treat RA, but
could include other therapies as well. The primary objective of both TASKi 2
and TASKi 3 is to measure the efficacy of R788 as determined by ACR20 scores
(American College of Rheumatology responder rates showing a minimum of 20%
improvement in RA symptoms and pain) at 6 months and 3 months, respectively.
Secondary objectives include comparing higher ACR response rates (ACR 50 and
ACR 70) and DAS28 (Disease Activity Score including a 28-joint inspection)
rates, in addition to evaluating various safety measures. TASKi 3 will also
include measurement of changes in bone morphology using magnetic resonance
imaging (MRI) scans.&#160; Initial results of
the clinical trials are expected to be available by late summer 2009.</font></p>

is mediated by IgG signaling, and R788 is a potent inhibitor of IgG signaling.
In preclinical studies, R788 was shown to improve thrombocytopenia in an ITP
mouse model. We recently completed an exploratory Phase 2 clinical trial of
R788 to evaluate its safety and initial efficacy in chronic ITP patients. In
this clinical trial, R788 was orally administered in varying doses for 30 or
more days and demonstrated that it can improve platelet counts in highly
refractory patients. We have postponed expanding this clinical trial of R788 in
ITP until we have further clarity on development priorities from a potential
partner for R788.</p>

clinical trial of R788 in patients with relapsed or refractory B-cell
non-Hodgkin&#146;s lymphoma (NHL).&#160; We
reported favorable responses for patients suffering from small lymphocytic
lymphoma/chronic lymphocytic leukemia (SLL/CLL) or from diffuse large B-cell

agreement with Merck Serono that gave Merck Serono an exclusive license to
develop and commercialize inhibitors in our aurora kinase program, including
R763/AS703569. In November&nbsp;2007, Merck Serono exercised its option to add
Japan to the territories covered under the current aurora kinase collaboration
with respect to R763/AS703569, resulting in a milestone payment to us of $3.0
million. Under the agreement, Merck Serono is responsible for the further
development and commercialization of R763/AS703569. In September&nbsp;2006,
Merck Serono initiated a Phase 1 multi-center clinical trial to evaluate
R763/AS703569 for the treatment of patients with refractory solid tumors. In February&nbsp;2007,
Merck Serono began an additional Phase 1 clinical trial evaluating
R763/AS703569 in patients with hematological malignancies. In July&nbsp;2007,
Merck Serono initiated its third Phase 1 clinical trial, designed to determine
the maximum tolerated dose, safety and dosing regimen of R763/AS703569 in
combination with gemcitabine, a commonly prescribed chemotherapeutic agent
administered by intravenous infusion. The clinical trial is evaluating two
different treatment regimens in which R763/AS703569 is given in sequence with
gemcitabine over 21-day cycles. As many as 72 patients with advanced
malignancies, including pancreatic, ovarian, breast, non-small cell lung and
colorectal, will be evaluated.</p>

</i>In the first quarter of 2005, we announced a collaborative
research and license agreement with Pfizer for the development of inhaled
products for the treatment of allergic asthma and other respiratory diseases,
such as chronic obstructive pulmonary disease. The collaboration initially
focused on our preclinical small molecule compounds, which inhibit
immunoglobulin E, or IgE, receptor signaling in respiratory tract mast cells by
blocking Syk, a novel drug target for respiratory diseases. Mast cells play
important roles in both early and late phase allergic reactions, and Syk
inhibitors could prevent both phases.</p>

issued Statement of Financial Accounting Standards, or SFAS, No.&nbsp;159, &#147;The
Fair Value Option for Financial Assets and Financial Liabilities&#151;including an
amendment of FASB Statement No.&nbsp;115.&#148; SFAS No.&nbsp;159 permits entities
to choose to measure financial instruments and certain other items at fair
value. Entities that elect the fair value option will report unrealized gains
and losses in earnings at each subsequent reporting date. The fair value option
may be elected on an instrument-by-instrument basis, with few exceptions. SFAS No.&nbsp;159
also establishes presentation and disclosure requirements to facilitate
comparisons between companies that choose different measurement attributes for
similar assets and liabilities. SFAS No.&nbsp;159 is effective for fiscal years
beginning after November&nbsp;15, 2007. We elected not to adopt the fair value

the Use of Estimates</font></b></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our discussion and analysis of our
financial condition and results of operations is based upon our condensed
financial statements, which have been prepared in accordance with U.S generally
accepted accounting principles for interim financial information. The
preparation of these condensed financial statements requires us to make
estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses, and related disclosure of contingent assets
and liabilities. We evaluate our estimates, including those related to terms of
the research collaborations (i.e. amortization of upfront fees and certain
milestone payments), investments, stock compensation, impairment issues, the
estimated useful life of assets and contingencies, on an on-going basis. We
base our estimates on historical experience and on various other assumptions
that we believe to be reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. Actual results
may differ from these estimates under different assumptions or conditions. We
believe that there were no significant changes in our critical accounting
policies during the quarter ended September&nbsp;30, 2008 as compared to those
previously disclosed in our annual report on Form&nbsp;10-K for the year ended December&nbsp;31,
2007. We believe the following critical accounting policies affect our more
significant judgments and estimates used in the preparation of our financial
statements:</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><b><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;font-weight:bold;">Revenue Recognition</font></i></b></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We recognize revenue from our
collaboration arrangements. Our revenue arrangements with multiple elements are
evaluated under Emerging Issues Task Force No.&nbsp;00-21, &#147;Revenue
Arrangements with Multiple Deliverables,&#148; and are divided into separate units
of accounting if certain criteria are met, including whether the delivered
element has stand-alone value to the customer and whether there is objective
and reliable evidence of the fair value of any undelivered items. The
consideration we receive is allocated among the separate units based on their
respective fair values, and the applicable revenue recognition criteria are
applied to each of the separate units. Advance payments received in excess of
amounts earned are classified as deferred revenue until earned.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Non-refundable, up-front payments
received in connection with research and development collaboration agreements,
including technology access fees, are deferred and recognized on a
straight-line basis over the relevant periods of continuing involvement, generally
the research term. When a research term is not specified, we estimate the time
it will take us to complete our deliverables under the contract and recognize
the upfront fee using the straight-line method over that time period. We review
our estimates every quarter for reasonableness.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Revenue related to collaborative
research with our corporate collaborators is recognized as research services
are performed over the related development periods for each contract. Under
these agreements, we are required to perform research and development
activities as specified in the applicable agreement. The payments received are
not refundable and are generally based on a contractual cost per full-time
equivalent employee working on the project. Research and development expenses
under the collaborative research agreements, except for the Merck collaboration
signed in November&nbsp;2004 related to ubiquitin ligases, approximate or
exceed the revenue recognized under such agreements over the term of the
respective agreements. For the Merck collaboration, we recognized a pro-rata
portion of the invoiced amounts for funding of our research scientists based on
the headcount dedicated to the project. When the research portion of the
collaboration ended in May&nbsp;2007, we recognized the full amount of the
deferred revenue related to the contract because we had no further obligations
under the Merck collaboration. It is our policy to recognize revenue based on
our level of effort expended, and that revenue recognized will not exceed
amounts billable under the arrangement.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
determination of the fair value of share-based payment awards on the date of
grant using the Black-Scholes option-pricing model is affected by our stock
price as well as assumptions regarding a number of complex and subjective
variables. These variables include, but are not limited to, volatility,
expected term, risk-free interest rate and dividends. We estimate volatility
using our historical share price performance over the expected life of the
option up to the point where we have historical market data. For expected term,
among other things, we take into consideration our historical data of options
exercised, cancelled and expired. The risk-free rate is based on the U.S.
Treasury constant maturity rate. We have not paid and do not expect to pay
dividends. In order to calculate share-based expense, we also estimate the
forfeiture rate using our historical experience with options that cancel before
they vest.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">If these
factors change and we employ different assumptions in the application of SFAS
123(R)&nbsp;in future periods, the compensation expense that we record under
SFAS 123(R)&nbsp;may differ significantly from what we have recorded in the
current period. Therefore, we believe it is important to be aware of the high
degree of subjectivity involved when using option pricing models to estimate
share-based compensation under SFAS 123(R).</font></p>

were no contract revenues reported during the three and nine months ended September&nbsp;30,
2008 or for the three months ended September&nbsp;30, 2007. Contract revenues
for the nine months ended September&nbsp;30, 2007 consisted of approximately
$2.5 million in full time employee, or FTE, revenue from Merck, approximately
$1.3 million in amortization of license and milestone payments from Merck and
approximately $0.8 million amortization of license payments from Pfizer. We had
no deferred revenue as of September&nbsp;30, 2008. Our potential revenues for
the remainder of 2008 is expected to only include revenues from any potential
new collaboration arrangements, if any, we may enter into the future.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
increase in research and development expenses for the three and nine months
ended September&nbsp;30, 2008, compared to the same periods in 2007, was
primarily due to an increase in clinical costs and stock-based compensation
expense, as discussed under &#147;Stock-Based Compensation&#148; below.&#160; The increase in clinical costs was primarily
attributable to increased costs associated with initiating and running our two
Phase 2b clinical trials and the extension trial of R788 in RA patients at
clinical research centers throughout the United States, Latin America, and
Europe, and manufacturing R788 material to be used in these clinical trials.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The scope
and magnitude of future research and development expenses are difficult to
predict given the number of clinical trials that we will need to conduct for
any of our potential products, as well as our limited capital resources. In
general, biopharmaceutical development involves a series of steps, beginning
with identification of a potential target and including, among others, proof of
concept in animals and Phase 1, 2 and 3 clinical studies in humans. Each of
these steps is typically more expensive than the previous step. Success in
early stages of development often results in increasing expenditures for a
given product candidate. Our research and development expenditures currently
include costs for scientific personnel, supplies, equipment, consultants,
sponsored research, allocated facility costs, costs related to preclinical and
clinical trials, and stock-based compensation.</font></p>

increase in general and administrative expenses for the three and nine months
ended September&nbsp;30, 2008, as compared to the same periods in 2007, was

associated with the increase in our patent portfolio.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Interest
expense results from our capital lease obligations associated with fixed asset
acquisitions. The decrease in interest expense for the three and nine months
ended September&nbsp;30, 2008, as compared to the same periods in 2007, was due
to lower interest rates on capital lease obligations outstanding during those
periods.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We
believe that our existing capital resources will be sufficient to support our
current operating plan through at least the next 12 months.&#160; Our forecast of the period of time through
which our capital resources will be adequate to support our current operating
plan is a forward-looking statement and involves risks and uncertainties, and
actual results could vary as a result of a number of factors, including the
factors discussed under Part&nbsp;II, Item 1A, &#147;Risk Factors&#148; of this Quarterly
Report on Form&nbsp;10-Q.&#160; We have based
this estimate on assumptions that may prove to be wrong, and we could utilize
our available capital resources sooner than we currently expect.&#160; Because of the numerous risks and
uncertainties associated with the development of our product candidates and
other research and development activities, including risks and uncertainties
that could impact the rate of progress of our development activities, we are
unable to estimate with certainty the amounts of increased capital outlays and
operating expenditures associated with our current and anticipated clinical
trials and other research and development activities.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;"><a href="#TableOfContents" title="Click to go to Table of Contents">Table of Contents</a></font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In the
foreseeable future, our operations will require significant additional funding,
in large part due to our research and development expenses, future preclinical
and clinical testing costs and the absence of any revenues from product sales.
The amount of future funds needed will depend largely on the timing and
structure of potential future collaborations.&#160;
Until we can generate a sufficient amount of product revenue, we expect
to finance future cash needs through public or private equity offerings, debt
financings or collaboration and licensing arrangements, as well as through
interest income earned on the investment of our cash balances and short-term
investments.&#160; With the exception of
milestone and royalty payments that we may receive under our existing
collaborations, we do not currently have any commitments for future
funding.&#160; Our ability to raise funds may
be adversely impacted by current economic conditions, including the effects of
the recent disruptions to the credit and financial markets in the U. S. and
worldwide. As a result of these and other factors, we do not know whether additional
financing will be available when needed, or that, if available, we will be able
obtain financing on terms favorable to our stockholders or us.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To the
extent we raise additional capital by issuing equity securities, our
stockholders may experience substantial dilution. To the extent that we raise
additional funds through collaboration and licensing arrangements, we may be
required to relinquish some of our rights to our technologies or product
candidates, or grant licenses on terms that are not favorable to us.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Insufficient
funds may require us to delay, scale back or eliminate some or all of our
research or development programs, to lose rights under existing licenses or to
relinquish greater or all rights to product candidates at an earlier stage of
development or on less favorable terms than we would otherwise choose or may
adversely affect our ability to operate as a going concern. As of September&nbsp;30,
2008, we had approximately $160.4 million in cash, cash equivalents and
available-for-sale securities, as compared to approximately $108.3 million as
of December&nbsp;31, 2007, an increase of approximately $52.1 million. The
increase was primarily attributable to net proceeds of approximately $127.5
million from our public offering in the first quarter of 2008, offset by
operating spending for the nine months ended September&nbsp;30, 2008. For the
nine months ended September&nbsp;30, 2008 and 2007, we maintained an investment
portfolio primarily in money market funds, U. S. treasury bills,
government-sponsored enterprise securities, corporate bonds and commercial
paper. Cash in excess of immediate requirements is invested with regard to
liquidity and capital preservation. Wherever possible, we seek to minimize the
potential effects of concentration and degrees of risk.</font></p>

have concluded that our disclosure controls and procedures (as defined in Rules&nbsp;13a-15(e)&nbsp;and

effective as of September&nbsp;30, 2008.</p>

well conceived and operated, can provide only reasonable, not absolute,
assurance that the objectives of the controls are met. Because of the inherent
limitations in all control systems, no evaluation of controls can provide
absolute assurance that all control issues, if any, within a company have been
detected. Accordingly, our disclosure controls and procedures are designed to
provide reasonable, not absolute, assurance that the objectives of our
disclosure control system are met and, as set forth above, our chief executive
officer and chief financial officer have concluded, based on their evaluation
as of the end of the period covered by this quarterly report on Form&nbsp;10-Q,
that our disclosure controls and procedures were sufficiently effective to
provide reasonable assurance that the objectives of our disclosure control
system were met.</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have consumed
substantial amounts of capital to date, and our operating expenditures are
expected to increase over the next several years as we expand our research and
development activities.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We believe that our
existing capital resources will be sufficient to support our current operating
plan through at least the next 12 months.&#160;
Our forecast of the period of time through which our capital
resources will be adequate to support our current operating plan is a forward-looking
statement and involves risks and uncertainties, and actual results could vary
as a result of a number of factors, including the factors discussed under this
section.&#160; We have based this estimate on
assumptions that may prove to be wrong, and we could utilize our available
capital resources sooner than we currently expect.&#160; Because of the numerous risks and
uncertainties associated with the development of our product candidates and
other research and development activities, including risks and uncertainties
that could impact the rate of progress of our development activities, we are
unable to estimate with certainty the amounts of increased capital outlays and
operating expenditures associated with our current and anticipated clinical
trials and other research and development activities.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In the foreseeable future, our
operations will require significant additional funding, in large part due to
our research and development expenses, future preclinical and clinical-testing
costs, and the absence of any revenues from product sales. The amount of future
funds needed will depend largely on the timing and structure of potential
future collaborations.&#160; Until we can
generate a sufficient amount of product revenue, we expect to finance future
cash needs through public or private equity offerings, debt financings or
collaboration and licensing arrangements, as well as through interest income
earned on the investment of our cash balances and short-term investments.&#160; With the exception of milestone and royalty payments
that we may receive under our existing collaborations, we do not currently have
any commitments for future funding.&#160; Our
ability to raise funds may be adversely impacted by current economic
conditions, including the effects of the recent disruptions to the credit and
financial market in the U. S. and worldwide. As a result of these and other
factors, we do not know whether additional financing will be available when
needed, or that, if available, we will obtain financing on terms favorable to
our stockholders or us.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To the extent we raise additional
capital by issuing equity securities, our stockholders could at that time
experience substantial dilution. To the extent that we raise additional funds
through collaboration and licensing arrangements, we may be required to
relinquish some rights to our technologies or product candidates, or grant
licenses on terms that are not favorable to us.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Due in large part
to the significant research and development expenditures required to identify
and validate new product candidates and pursue our development efforts, we have
not been profitable and have incurred operating losses since we were
incorporated in June&nbsp;1996.&#160; The
extent of our future losses and the timing of potential profitability are
highly uncertain, and we may never achieve profitable operations. We incurred
net losses of approximately $37.7 million and $99.0 million for the three and
nine months ended September&nbsp;30, 2008, $74.3 million in fiscal year 2007
and $37.6 million in fiscal year 2006. Currently, our revenues are generated
solely from research milestone payments pursuant to our collaboration
agreements and licenses and are insufficient to generate profitable operations.
As of September&nbsp;30, 2008, we had an accumulated deficit of approximately
$468.4 million. We expect to incur losses for at least the next several years
and expect that these losses could increase as we expand our research and
development activities and incur significant clinical and testing costs.</font></p>

the present time, the majority of our operations are in various stages of drug
identification and development. We currently have four product compounds in the
clinical testing stage: one with indications for RA, ITP and B-cell lymphoma,
which is proprietary to our company; one in safety testing and intended for
psoriasis, RA, and other immunological indications, which is proprietary to our
company; one with six indications for oncology, which is subject to a
collaboration agreement with Merck Serono; and one in safety testing and
intended for allergic asthma, which is subject to a collaboration agreement
with Pfizer. In our industry, it is statistically unlikely that the limited
number of compounds that we have identified as potential product candidates
will actually lead to successful product development efforts, and we do not
expect any drugs resulting from our research to be commercially available for
several years, if at all.</font></p>

compounds in clinical trials and our future leads for potential drug compounds
are subject to the risks and failures inherent in the development of
pharmaceutical products. These risks include, but are not limited to, the
inherent difficulty in selecting the right drug and drug target and avoiding
unwanted side effects as well as unanticipated problems relating to product
development, testing, regulatory compliance, manufacturing, competition and
costs and expenses that may exceed current estimates. For example, in our
recently completed Phase 2a clinical trial for R788 in rheumatoid arthritis, </font>the
most common clinically meaningful adverse events noted in the clinical trial
included dose-related neutropenia, mild elevations of liver function tests and
gastrointestinal side effects.&#160; In larger future clinical trials, we may discover additional
side effects and/or higher frequency of side effects than those observed in
completed clinical trials. If approved by the U.S. Food and Drug Administration,
or FDA, the side effect profile of R788 may also result in a narrowly approved
indication for use of the product, especially in light of other drugs currently
available to treat RA, dependent on the safety profile of R788 relative to
those drugs.</p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The results of
preliminary studies do not necessarily predict clinical or commercial success,
and larger later-stage clinical trials may fail to confirm the results observed
in the preliminary studies. Our lead product candidate is in early development,
having recently completed initial Phase 2 clinical trials in two indications.
We are conducting additional Phase 2b trials, with larger numbers of patients,
before proceeding into Phase 3 trials with R788 for RA. Furthermore, our Phase
2 clinical trial for ITP was conducted in highly refractory patients, as
opposed to treatment-naive patients. If efficacy is not demonstrated among
treatment-naive patients, any approved indication for ITP will be limited to a
subset of the patient population. Finally, with respect to our own compounds in
development, we have established anticipated timelines with respect to the
initiation or completion of clinical studies based on existing knowledge of the
compound. However, we cannot provide assurance that we will meet any of these
timelines for clinical development.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Because of the
uncertainty of whether the accumulated preclinical evidence (pharmacokinetic,
pharmacodynamic, safety and/or other factors) or early clinical results will be
observed in later clinical trials, we can make no assurances regarding the
likely results from our future clinical trials or the impact of those results
on our business.</font></p>

of our product candidates depends upon successful completion of preclinical
studies and clinical trials. Preclinical testing and clinical development are
long, expensive and uncertain processes. We do not know whether we, or any of
our collaborative partners, will be permitted to undertake clinical trials of
potential products beyond the trials already concluded and the trials currently
in process. It will take us, or our collaborative partners several years to
complete any such testing, and failure can occur at any stage of testing.
Interim results of trials do not necessarily predict final results, and
acceptable results in early trials may not be repeated in later trials. A
number of companies in the pharmaceutical industry, including biotechnology
companies, have suffered significant setbacks in advanced clinical trials, even
after achieving promising results in earlier trials. Moreover, we or our
collaborative partners or regulators may decide to discontinue development of
any or all of these projects at any time for commercial, scientific or other
reasons.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Significant delays
in clinical testing could materially impact our product development costs and
timing. We do not know whether planned clinical trials will begin on time, will
need to be halted or revamped or will be completed on schedule, or at all.
Clinical trials can be delayed for a variety of reasons, including delays in
obtaining regulatory approval to commence a study, delays from scale up, delays
in reaching agreement on acceptable clinical study agreement terms with
prospective clinical sites, delays in obtaining institutional review board
approval to conduct a study at a prospective clinical site or delays in
recruiting subjects to participate in a study.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In addition, we
typically rely on third-party clinical investigators to conduct our clinical
trials and other third-party organizations to oversee the operations of such
trials and to perform data collection and analysis. As a result, we may face
additional delaying factors outside our control if these parties do not perform
their obligations in a timely fashion. While we have not yet experienced delays
that have materially impacted our clinical trials or product development costs,
delays of this sort could occur for the reasons identified above or other
reasons. If we have delays in testing or approvals, our product development
costs will increase. For example, we may need to make additional payments to
third-party investigators and organizations to retain their services or we may
need to pay recruitment incentives. If the delays are significant, our
financial results and the commercial prospects for our product candidates will
be harmed, and our ability to become profitable will be delayed.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We currently do not
have manufacturing capabilities or experience necessary to produce our product
candidate R788. We rely on a single manufacturer of R788 for our R788 clinical
trials. We will rely on manufacturers to deliver materials on a timely basis
and to comply with applicable regulatory requirements, including the FDA&#146;s
current Good Manufacturing Practices, or GMP. These outsourcing efforts with
respect to manufacturing preclinical and clinical supplies will result in a
dependence on our suppliers to timely manufacture and deliver sufficient
quantities of materials produced under GMP conditions to enable us to conduct
planned preclinical studies, clinical trials and, if possible, to bring
products to market in a timely manner.</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our current and
anticipated future dependence upon these third-party manufacturers may
adversely affect our ability to develop and commercialize product candidates on
a timely and competitive basis. These manufacturers may not be able to produce
material on a timely basis or manufacture material at the quality level or in
the quantity required to meet our development timelines and applicable
regulatory requirements. We may not be able to maintain or renew our existing
third-party manufacturing arrangements, or enter into new arrangements, on
acceptable terms, or at all. Our third-party manufacturers could terminate or
decline to renew our manufacturing arrangements based on their own business
priorities, at a time that is costly or inconvenient for us. If we are unable
to contract for the production of materials in sufficient quantity and of
sufficient quality on acceptable terms, our planned clinical trials may be
significantly delayed. Manufacturing delays could postpone the filing of our
investigational new drug, or IND, applications and/or the initiation of
clinical trials that we have currently planned.</font></p>

manufacturers may not be able to comply with the GMP regulations, other
applicable FDA regulatory requirements or similar regulations applicable
outside of the United States. Additionally, if we are required to enter into
new supply arrangements, we may not be able to obtain approval from the FDA of any
alternate supplier in a timely manner, or at all, which could delay or prevent
the clinical development and commercialization of any related product
candidates. Failure of our third-party manufacturers or us to obtain approval
from the FDA or to comply with applicable regulations could result in sanctions
being imposed on us, including fines, civil penalties, delays in or failure to
grant marketing approval of our product candidates, injunctions, delays,
suspension or withdrawal of approvals, license revocation, seizures or recalls
of products and compounds, operating restrictions and criminal prosecutions,
any of which could significantly and adversely affect our business.</font></p>

<p style="font-weight:bold;margin:0in 0in .0001pt;text-autospace:none;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;">Because
most of our expected future revenues are contingent upon collaborative and

generate revenue in the near term depends on our ability to enter into
additional collaborative agreements with third parties and to maintain the
agreements we currently have in place. Our ability to enter into new
collaborations and the revenue, if any, that may be recognized under these
collaborations is highly uncertain. If we are unable to enter into new
collaborations, our business prospects could be harmed, which could have an
immediate adverse effect on the trading price of our stock. </font>Our ability to enter into a collaboration may
be&nbsp;dependent on many factors such as the fit of one of our programs with
another company&#146;s regulatory risk tolerance, their patent portfolio expiration
timeline, clinical pipeline, overall corporate goals and financial position.</p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;">&nbsp;</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To date, most of
our revenues have been related to the research phase of each of our
collaborative agreements. Such revenues are for specified periods, and the
impact of such revenues on our results of operations is partially offset by
corresponding research costs. Following the completion of the research phase of
each collaborative agreement, additional revenues may come only from milestone
payments and royalties, which may not be paid, if at all, until some time well
into the future. The risk is heightened due to the fact that unsuccessful
research efforts may preclude us from receiving any milestone payments under
these agreements. Our receipt of revenues from collaborative arrangements is
also significantly affected by the timing of efforts expended by us and our
collaborators and the timing of lead compound identification. We have received
milestone payments from Johnson&nbsp;&amp; Johnson, Novartis, Daiichi, Merck,
Merck Serono and Pfizer. Under many agreements, however, milestone payments may
not be earned until the collaborator has advanced product candidates into
clinical testing, which may never occur or may not occur until some time well
into the future. If we are not able to generate revenue under our
collaborations when and in accordance with our expectations or the expectations
of industry analysts, this failure could harm our business and have an
immediate adverse effect on the trading price of our stock.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our business
requires us to generate meaningful revenue from royalties and licensing
agreements. To date, we have not received any revenue from royalties for the
commercial sale of drugs, and we do not know when we will receive any such
revenue, if at all. Likewise, we have not licensed any lead compounds or drug
development candidates to third parties, and we do not know whether any such
license will be entered into on acceptable terms in the future, if at all.</font></p>

our current corporate collaborations or license agreements are unsuccessful,
our research and development efforts could be delayed.</font></b></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our strategy
depends upon the formation and sustainability of multiple collaborative
arrangements and license agreements with third parties in the future. We rely
on these arrangements for not only financial resources, but also for expertise
that we expect to need in the future relating to clinical trials,
manufacturing, sales and marketing, and for licenses to technology rights. To
date, we have entered into several such arrangements with corporate
collaborators; however, we do not know if such third parties will dedicate
sufficient resources or if any development or commercialization efforts by
third parties will be successful. Should a collaborative partner fail to
develop or commercialize a compound or product to which it has rights from us
for any reason including corporate restructuring, such failure might delay
ongoing research and development efforts at Rigel, because we might not receive
any future milestone payments, and we would not receive any royalties
associated with such compound or product. In addition, the continuation of some
of our partnered drug discovery and development programs may be dependent on
the periodic renewal of our corporate collaborations.</font></p>

research phases conducted at our facilities under our broad collaboration with
Novartis ended in 2004. The research phase of our corporate collaboration
agreement with Daiichi ended in 2005. In 2004, we signed a new corporate
collaboration with Merck, and the research phase of this collaboration ended in
May&nbsp;2007. In 2005, we signed additional collaborations with Pfizer and
Merck Serono. Each of our collaborations could be terminated by the other party
at any time, and we may not be able to renew these collaborations on acceptable
terms, if at all, or negotiate additional corporate collaborations on
acceptable terms, if at all. If these collaborations terminate or are not

particular compounds. While our existing collaborative agreements typically
provide that we retain milestone payments and royalty rights with respect to

rights may be at reduced rates, and disputes may arise over the application of
derivative payment provisions to such drugs, and we may not be successful in

the United States Patent and Trademark Office. Interferences are complex and
expensive legal proceedings and there is no assurance we will be successful in
such proceedings. An interference could result in our losing our patent rights

Additional uncertainty may result because no consistent policy regarding the

secrets to protect technology where we believe patent protection is not
appropriate or obtainable; however, trade secrets are difficult to protect.

certain in-license agreements that are important to our business, and we
generally do not control the prosecution of in-licensed technology.
Accordingly, we are unable to exercise the same degree of control over this
intellectual property as we exercise over our internally-developed technology.
Moreover, some of our academic institution licensors, research collaborators
and scientific advisors have rights to publish data and information in which we
have rights. If we cannot maintain the confidentiality of our technology and
other confidential information in connection with our collaborations, then our
ability to receive patent protection or protect our proprietary information
will be impaired. In addition, some of the technology we have licensed relies
on patented inventions developed using U.S. government resources. The U.S.
government retains certain rights, as defined by law, in such patents, and may
choose to exercise such rights. Certain of our in-licenses may be terminated if
we fail to meet specified obligations. If we fail to meet such obligations and
any of our licensors exercise their termination rights, we could lose our
rights under those agreements. If we lose any of our rights, it may adversely
affect the way we conduct our business. In addition, because certain of our
licenses are sublicenses, the actions of our licensors may affect our rights
under those licenses.</font></p>

FDA approval to market a product, we must demonstrate that the product is safe
and effective in the patient population and the indication that will be
treated. Data obtained from preclinical and clinical activities are susceptible
to varying interpretations that could delay, limit or prevent regulatory
approvals. In addition, delays or rejections may be encountered based upon
additional government regulation from future legislation or administrative
action or changes in FDA policy during the period of product development,
clinical trials and FDA regulatory review. Failure to comply with applicable
FDA or other applicable regulatory requirements may result in criminal
prosecution, civil penalties, recall or seizure of products, total or partial
suspension of production or injunction, as well as other regulatory action
against our potential products or us. Additionally, we have limited experience
in conducting and managing the clinical trials necessary to obtain regulatory
approval.</font></p>

approval of a product is granted, this approval will be limited to those
indications or disease states and conditions for which the product is
demonstrated through clinical trials to be safe and efficacious. We cannot
ensure that any compound developed by us, alone or with others, will prove to
be safe and efficacious in clinical trials and will meet all of the applicable
regulatory requirements needed to receive marketing approval.</font></p>

collaborators&#146; ability to develop and commercialize pharmaceutical products
based on this technology, as well as our ability to attract and retain
qualified personnel, obtain patent protection or otherwise develop proprietary

cost. Our ability to commercially exploit a drug may be limited due to the
continuing efforts of government and third-party payors to contain or reduce
the costs of health care through various means. For example, in some foreign
markets, pricing and profitability of prescription pharmaceuticals are subject
to government control. In the United States, we expect that there will continue
to be a number of federal and state proposals to implement similar government
control. In addition, increasing emphasis on managed care in the United States
will likely continue to put pressure on the pricing of pharmaceutical products.
Cost control initiatives could decrease the price that any of our collaborators
would receive for any products in the future. Further, cost control initiatives
could adversely affect our collaborators&#146; ability to commercialize our products

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Significant
uncertainty exists as to the reimbursement status of newly-approved healthcare
products. Third-party payors, including Medicare, are challenging the prices
charged for medical products and services. Government and other third-party
payors increasingly are attempting to contain healthcare costs by limiting both
coverage and the level of reimbursement for new drugs and by refusing, in some
cases, to provide coverage for uses of approved products for disease
indications for which the FDA 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
third-party payors do not provide adequate coverage and reimbursement levels
for our products, the market acceptance of these products may be reduced.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The testing and
marketing of medical products entail an inherent risk of product liability. If
we cannot successfully defend ourselves against product liability claims, we
may incur substantial liabilities or be required to limit commercialization of
our products. We are not currently aware of any specific causes for concern
with respect to clinical liability claims. We carry product liability insurance
that is limited in scope and amount and may not be adequate to fully protect us
against product liability claims. 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
pharmaceutical products we develop, alone or with corporate collaborators. We,
or our corporate collaborators, might not be able to obtain insurance at a
reasonable cost, if at all. While under various circumstances we are entitled
to be indemnified against losses by our corporate collaborators,
indemnification may not be available or adequate should any claim arise.</font></p>

drug discovery and development programs depends, in part, on continued
collaborations with certain of these consultants and advisors. We, and various
members of our management and research staff, rely on certain of these
consultants and advisors for expertise in our research, regulatory and clinical
efforts. Our scientific advisors are not our employees and may have commitments
to, or consulting or advisory contracts with, other entities that may limit
their availability to us. We do not know if we will be able to maintain such
consulting agreements or that such scientific advisors will not enter into
consulting arrangements, exclusive or otherwise, with competing pharmaceutical
or biotechnology companies, any of which would have a detrimental impact on our
research objectives and could have a material adverse effect on our business,
financial condition and results of operations.</font></p>

radioactive compounds. We cannot completely eliminate the risk of accidental
contamination or injury from the use, storage, handling or disposal of these

damages that result, and such liability could exceed our resources. We are also
