Act. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. We believe all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation
have been included herein. Operating results for the three and six months ended June 30, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010 or any other future period. The
condensed balance sheet at December 31, 2009 has been derived from the audited financial statements at that date. You should read these condensed financial statements and notes in conjunction with our audited financial statements for the year
ended December 31, 2009, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 2, 2010.

Need for Additional Capital

We have incurred net losses since inception and we expect to incur substantial and increasing losses for at least the next several years
as we continue our research and development activities. To date, we have funded operations primarily through the sale of equity securities, non-equity payments from collaborators and interest income. Future revenue, if any, for at least the next few
years is expected to consist primarily of payments under corporate collaborations and interest income. The process of developing our products will require significant additional research and development, preclinical testing and clinical trials, as
well as regulatory approval. We expect these activities, together with general and administrative expenses, to result in substantial operating losses for the foreseeable future. We will not receive product revenue unless we, or our collaborative
partners, complete clinical trials, obtain regulatory approval and successfully commercialize one or more of our products.

We
expect continuing losses over the next several years. We plan to obtain capital through public or private equity or debt financing, capital lease financing and collaborative arrangements with corporate partners. We may have to seek other sources of
capital or re-evaluate our operating plans if we are unable to consummate some or all of the capital financing arrangements noted above. We believe our existing cash resources will be sufficient to satisfy our current operating plan until the end of
2011.

Use of Estimates

In preparing our financial statements to conform with GAAP, we make estimates and assumptions that affect the amounts reported in our
financial statements and accompanying notes. Actual results may differ from these estimates.

Cash and Cash Equivalents,
Short-Term and Long-Term Investments

We invest our excess cash in money market funds, cash deposits, U.S. treasury and
U.S. government agency securities, taxable municipal notes, some of which may have an auction reset feature (auction rate securities, or ARS), and corporate notes. All investments with stated maturities of three months or less from date of purchase
are classified as cash equivalents. Debt securities with original maturities greater than three months and remaining maturities less than one year and all our ARS including perpetual rate securities are classified as short-term investments based on
our intention to sell these securities in less than one year. Debt securities with remaining maturities greater than one year and which we intend to hold until maturity are classified as long-term investments. We classify all cash equivalents and
non-ARS investments as available-for-sale. Available-for-sale securities are carried at estimated fair value, with unrealized gains and losses reported as a component of accumulated other comprehensive income (loss). Realized gains or losses on the
sale of investments are determined on a specific identification method, and such gains and losses are reflected as a component of interest income.

Due to the unprecedented events in the ARS market and our November 2008 ARS rights
agreement with UBS AG and with its affiliates, or UBS, we elected a one-time transfer of our ARS investments from the classification of available-for-sale to trading securities under ASC 320, Investments-Debt and Equity Securitiesduring the fourth quarter of fiscal 2008. Trading securities are carried at estimated fair value, with gains and losses resulting from changes in fair value reported in earnings.

Marketable security investments are evaluated periodically for impairment. We take into account general market conditions, changes in
economic environment as well as specific investment attributes, such as credit downgrade or illiquidity for each investment, the expected cash flows from the security, our intent to sell the security and whether or not we will be required to sell
the security before the recovery of its amortized cost, to estimate the fair value of our investments and to determine whether impairment is other than temporary. If it is determined that a decline in fair value of any investment is other than
temporary, then the unrealized loss related to credit risk would be included in interest and other income (expense), net.

Fair Value of Financial Instruments

We used the provisions of ASC 820, Fair Value Measurements and Disclosure, to determine the fair values of our
financial assets and liabilities using the fair value hierarchy. ASC 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosure about fair value measurements. The
objective of fair value measurement is to determine the price that would be received to sell the asset or paid to transfer the liability (an exit price) in an orderly transaction between market participants at the measurement date. The statement
emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and that market participant assumptions include assumptions about risk and effect of a restriction on the sale or use of an asset. To increase consistency
and comparability in fair value measurement and related disclosures, this statement establishes a fair value hierarchy that prioritize the inputs to valuation techniques used to measure fair value into three broad levels: (1) Level 1 inputs are
quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; (2) Level 2 inputs are inputs other than quoted prices included in Level 1 that are
observable for the asset or liability, either directly or indirectly through corroboration with observable market data; and (3) Level 3 inputs are unobservable inputs for asset or liability that reflect the reporting entitys own
assumptions about risk and the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

We recorded the fair values of our treasury bills, treasury notes and government agencies securities based on a monthly report provided
by our investment provider. Since these government securities generally have market prices from multiple sources and it can be difficult to select the best individual price directly from the quoted prices in the active markets, our investment
provider uses Level 2 inputs for the valuation of these securities. Using the Level 2 inputs, a consensus price or a weighted average price for each of these securities can be derived from a distribution-curve-based algorithm which
includes market prices obtained from a variety of industrial standard data providers (e.g. Bloomberg), security master files from large financial institutions, and other third-party sources.

With the current financial market conditions, the assessment of fair values of certain financial instruments can be difficult and
subjective. For our ARS and put option, we use Level 3 inputs to determine their fair values since they do not have a readily determinable market value. The assumptions used in valuing the ARS and the put option included, basing on data as of the
reporting period then ended, interest rates, tax status, credit quality, expected holding periods of the ARS, insurance wraps, the portfolio composition of Federal Family Education Loan Program, or FFELP, and private loans, likelihood of redemption,
loan rates per the UBS Rights offering and bearer risk associated with UBSs financial ability to repurchase the ARS beginning June 30, 2010. These assumptions are volatile and subject to change, and therefore could result in significant
changes to the fair values of these financial instruments. See Notes 5, 7 and 10 to Condensed Financial Statements for additional information.

Recent Accounting Pronouncements

With the exception of those discussed below, there have been no recent accounting pronouncements or changes in accounting pronouncements
during the six months ended June 30, 2010, as compared to the recent accounting pronouncements described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009, that are of significance, or potential significance to
us.

In January 2010, the FASB issued Accounting Standard Update No. 2010-06, Fair Value Measurements and Disclosures
(Topic 820): Improving Disclosures about Fair Value Measurements, ASU 2010-06, to improve disclosures related to fair value measurements. This guidance requires new disclosures as well as clarifies certain existing disclosure
requirements. Under ASU 2010-06, companies are required to provide separate information about significant transfers in and out of Level 1 and Level 2 of the fair value hierarchy as well as the reasons for such transfers, and a reconciliation of
purchases, sales, issuances, and settlements activities valued using Level 3 inputs on a gross basis. ASU 2010-06 also clarifies the requirement to determine the level of disaggregation for fair value measurement disclosures and the requirement to
disclose valuation techniques and inputs used for both recurring and nonrecurring fair value measurements in either Level 2 or Level 3. ASU 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, except
for the disclosure about purchases, sales, issuances, and settlements in the rollforward of activity for Level 3 fair value measurement which will be effective for fiscal years beginning after December 15, 2010, and for interim periods within
those fiscal years. We adopted ASU 2010-06 for Level 1 and 2 disclosure requirements in the quarter ended March 31, 2010. The adoption of this guidance increases the level of disclosures in our financial statements related to fair value
measurements.

On February 24, 2010, the FASB issued ASU No. 2010-09, Subsequent Events
(Topic 855)Amendments to Certain Recognition and Disclosure Requirements, ASU 2010-09. ASU 2010-09 removes the requirement that SEC filers disclose the date through which subsequent events have been evaluated. This
amendment alleviates potential conflicts between Subtopic 855-10 and the SECs requirements. We have adopted this guidance since its issuance.

Because we had a net operating loss carryforward as of June 30, 2010, no tax
benefits for the tax deductions related to stock-based compensation expense were recognized in our condensed statements of operations. Additionally, no incremental tax benefits were recognized from stock options exercised in the three and six months
ended June 30, 2010 and 2009, which would have resulted in a reclassification to reduce net cash provided by operating activities with an offsetting increase in net cash provided by financing activities. As of June 30, 2010,
$2.1 million of total unrecognized compensation costs, net of forfeitures, related to non-vested service based awards is expected to be recognized over a weighted average period of 1.47 years.

3. Comprehensive Loss

Comprehensive loss consists of net loss and other comprehensive income (loss). Other comprehensive income (loss) includes changes in
unrealized gains (losses) on investments. The activity in comprehensive loss was as follows:

4. Basic and Diluted Net Loss per Share

Basic and diluted net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during
the period.

Outstanding options to purchase 12,398,912 and 9,450,802 shares of our common stock for the three months ended
June 30, 2010 and 2009; and 12,478,675 and 9,647,855 shares of our common stock for the six months ended June 30, 2010 and 2009 were excluded from the diluted net loss per common share calculations because inclusion of such options would
be anti-dilutive.

5. Fair Value Measurements on a Recurring Basis

We measure certain financial assets at fair value on a recurring basis, including cash equivalents, available-for-sale securities, trading
securities and put options. The fair value of these financial assets was determined based on a three-tier fair value hierarchy as described in Note 1, which prioritizes the inputs used in measuring fair value.

The following table presents information about our financial assets that are measured at fair value on a recurring basis as of
June 30, 2010 and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value:

On February 12, 2010, UBS repurchased $4.0 million of our ARS from the original balance of $13.8
million. At June 30, 2010, our ARS had an aggregate fair value of $8.7 million and par value of $9.8 million. The ARS investments, purchased through our investment account with UBS at par value, have an auction reset

feature. Historically, the fair value of ARS investments approximated par value due to the frequent resets through the auction process. Beginning in late 2007, our securities invested in ARS
failed to settle in scheduled auctions due to liquidity crises. An auction failure means that the parties wishing to sell securities could not make the sale, but does not result in the securities going into default because the issuer continues to
pay interest. The interest rates may be reset to predetermined penalty or maximum rates based on mathematical formulas in accordance with each securitys prospectus. While we continue to earn interest on our ARS
investments at the contractual rate, these investments are not currently trading and therefore do not have a readily determinable market value. Accordingly, the estimated fair value of the ARS no longer approximates par value.

We estimated the fair value of our ARS after consideration of several factors, including input provided by UBS. Valuation techniques
involved the use of a discounted cash flow approach. Although these securities would typically be measured using Level 2 inputs, the failure of auctions and the lack of market activity required that these securities be measured using Level 3 inputs.
The assumptions used in preparing the discounted cash flow model to determine the fair value of our auction preferred stock take into account factors such as interest rates, credit quality, likelihood of redemption, duration and credit default swap
data points for monoline insurers. The underlying assets of our auction rate certificates are primarily comprised of student loans, and their fair values were measured by considering factors such as interest rates, tax status, credit quality,
duration, insurance wraps, the portfolio composition of Federal Family Education Loan Program, or FFELP, and private loans and likelihood of redemption. These assumptions are highly subjective and involve significant judgment and are subject to
change as the underlying sources of these assumptions and market conditions change. For the six months ended June 30, 2010, we recorded (i) a reduction of approximately $2.4 million and $1.6 million in fair values of our put option and ARS
respectively, as a result of certain ARS repurchased by UBS in February 2010 and (ii) no gain or loss to interest and income, net due to offsetting changes in fair values of our ARS and put option. For additional information, see Notes 7 and 10
to Condensed Financial Statements.

|                           |  |                |       |                  |   |      
|Total                      |  | $              | 1,768 |                  | $ | 4,122
|                           |  |                |       |                  |   |      

On November 10, 2008, we entered into an
agreement with UBS whereby we received rights, or the Right, to sell all our ARS held in our UBS account at par value ($18.7 million) to UBS at any time during a two-year period beginning on June 30, 2010 and ending on July 2, 2012. If we
do not exercise the Right, our ARS will continue to accrue interest as determined by the auction process or the terms outlined in the prospectus of the ARS if the auction process fails. If the Right is not exercised on or before July 2, 2012,
it will expire and UBS will have no further obligation to buy our ARS. The Right is a nontransferable security registered with the SEC. UBSs obligations under the Right are not secured by its assets and do not require UBS to obtain any
financing to support its performance obligations under the Right. UBS has disclaimed any assurance that it will have sufficient financial resources to satisfy its obligations under the Right.

The enforceability of the Right results in a put option which is recognized as a separate freestanding asset and accounted for separately
from the ARS investment. On June 10, 2009 and February 12, 2010, UBS elected to repurchase a portion of our ARS under the agreement at par value of $4.9 million and $4.0 million, respectively. The put option was measured at its fair value
of $1.1 million at June 30, 2010, compared to fair value of $3.4 million at December 31, 2009. The decrease of $2.3 million was due primarily to a $2.4 million reduction in our put option as a result of UBS repurchase of a portion of our
ARS offset by an increase of $111,000 in fair value of our put option which was recorded in interest and other income, net in our Statement of Operations. We elected to measure the put option at fair value under ASC 825-10-25, which permits an
entity to elect the fair value option for recognized financial assets, in order to match the changes in the fair value of the ARS. We valued the Right using a discounted cash flow approach including estimates of, based on data available as of
June 30, 2010, interest rates, timing and amount of cash flow, adjusted for any bearer risk associated with UBSs financial ability to repurchase the ARS beginning June 30, 2010. These assumptions are volatile and subject to change as
the underlying sources of these assumptions and market conditions change.

Prior to accepting the UBS offer, we recorded our
ARS as available-for-sale investments, and therefore recorded resulting losses that were determined to be temporarily impaired in accumulated other comprehensive gain (loss) in stockholders equity. In connection with the acceptance of the UBS
offer in November 2008, resulting in a right to require UBS to purchase the ARS at par value beginning on June 30, 2010, we have reclassified our ARS subject to the Right and held by UBS from available-for-sale to trading under ASC 320. The
transfer to trading securities reflects our intent to exercise our put option during the period June 30, 2010 to July 3, 2012.

8. Notes Payable

In
connection with our acceptance of the offer to enter into the agreement with UBS whereby we received the Right to sell all our ARS at par value to UBS at any time during a two-year period beginning on June 30, 2010 and ending on July 2,
2012, UBS would also make available to us no net cost loans up to 75% of the market value of our ARS. A no net cost loan as defined in the agreement means that the loan will bear interest at a rate equal to the average rate
of interest paid or deemed paid to Telik on the pledged ARS such that the interest cost, net of interest received by us on the pledged ARS, will be zero. The no net cost loans must be repaid upon commencement of the exercise of the
Right. According to the Rights Agreement, the loan is payable on demand. If UBS should exercise its discretionary right to demand repayment of any portion of the loan prior to the date we can exercise our repurchase rights, UBS and certain of its
affiliates will arrange for

alternative financing on terms and conditions substantially the same as those contained in the loan, and if alternative financing cannot be established, then UBS or one of its affiliates will
purchase our pledged ARS at par. UBS obligation to arrange such alternative financing does not apply under certain circumstances, including, but not limited to, if we sell the ARS pledged as collateral. Proceeds of sales of our ARS will first
be applied to repayment of the credit line with the balance, if any, for our account.

On December 31, 2008, we entered
into a loan agreement with UBS and drew down $8 million with our ARS pledged as collateral. On June 10, 2009 and February 12, 2010, UBS elected to repurchase a portion of our ARS under the Rights Agreement at par value of $4.9 million and
$4.0 million, respectively. Proceeds from both sales of our ARS were applied to repayment of the credit line whereby $4.9 million was paid in June 2009 leaving a balance of $3.1 million due to UBS as of December 31, 2009. There was no interest
paid on the loan for the three months ended June 30, 2010 as the remaining balance of the loan was paid in full in February 2010. For the six months ended June 30, 2010, interest paid on the loan was approximately $6,000 which was offset
entirely by interest earned on the pledged securities.

9. Restructuring Plan

In February 2009, we implemented a restructuring plan to further reduce our operating expenses and to streamline our infrastructure to
focus on our most advanced preclinical and clinical development programs. As a result of the restructuring plan we reduced our workforce by 37 positions and recorded a charge of approximately $868,000 for the three months ended March 31, 2009
and an additional $83,000 in the quarter ended June 30, 2009. We paid $750,000 in the quarter ended March 31, 2009, $111,000 in the quarter ended June 30, 2009 and the remaining $90,000 in the quarter ended September 30, 2009, as
severance, payroll taxes and other personnel related costs.

10. Subsequent Events

On July 1, 2010, we exercised the Right to sell all our remaining ARS to UBS under the Rights Agreement at par value of $9.8 million.
As such, we no longer have any ARS investments in our portfolio. To date, we have not incurred any losses on our ARS investments, total par value of $18.7 million, as a result of the Rights Agreement with UBS.

On July 21, 2010, we received from The Nasdaq Stock Market (Nasdaq) a deficiency notice letter indicating that for 30
consecutive business days the bid price of our common stock has closed below the minimum $1.00 per share requirement for continued inclusion on The Nasdaq Capital Market under Marketplace Rule 5550(a)(2). In accordance with Marketplace
Rule 5810(c)(3)(A), we have 180 calendar days, or until January 18, 2011, to regain compliance.

Telik is engaged in the discovery and development of small molecule drugs. Our business strategy is to advance our product candidates
through Phase 2 clinical studies, and to enter into a partnership with a pharmaceutical or biotechnology company to assist in further development and commercialization, license product candidates outside our therapeutic focus, and identify and
develop additional drug product candidates.

We have incurred net losses since inception and expect to incur losses for the
next several years as we continue our research and development activities. During the six months ended June 30, 2010, loss from operations was $10.4 million and net loss was $10.3 million. Net cash used in operations for the six months ended
June 30, 2010 was $8.9 million and net cash, cash equivalents, investments and restricted investments at June 30, 2010 were $30.8 million. As of June 30, 2010, we had an accumulated deficit of $513.9 million.

Our expenses consist primarily of those incurred for research and development and general and administrative costs associated with our
operations. The process of carrying out the development of our product candidates to later stages of development and our research programs may require significant additional research and development expenditures, including for preclinical testing
and clinical trials, as well as for manufacturing development efforts and obtaining regulatory approval. We outsource our clinical trials and our manufacturing development activities to third parties to maximize efficiency and minimize our internal
overhead. To date, we have funded our operations primarily through the sale of equity securities, and from non-equity payments from collaborative partners.

We are subject to risks common to biopharmaceutical companies, including risks inherent in
our research, development and commercialization efforts, preclinical testing, clinical trials, uncertainty of regulatory and marketing approvals, enforcement of patent and proprietary rights, the need for future capital, potential competition, use
of hazardous materials and retention of key employees. In order for a product to be commercialized, it will be necessary for us to conduct preclinical tests and clinical trials, demonstrate efficacy and safety of our product candidates to the
satisfaction of regulatory authorities, obtain marketing approval, enter into manufacturing, distribution and marketing arrangements, obtain market acceptance and, in many cases, obtain adequate reimbursement from government and private insurers. We
cannot provide assurance that we will generate revenues or achieve and sustain profitability in the future.

We have carried
out three workforce reductions since 2007, the most recent of which was completed in February 2009. As a result of our restructuring plans, we believe our existing cash resources will be sufficient to satisfy our current operating plan until the end
of 2011. Changes in our research and development plans or other changes affecting our operating expenses may affect actual future consumption of existing cash resources as well. In any event, we will require substantial additional financing to fund
our operations in the future.

We expect that our quarterly and annual results of operations will fluctuate for the
foreseeable future due to several factors, including the timing and extent of our research and development efforts and the outcome of our clinical trial activities. The successful development of our products is uncertain. As such, an accurate
prediction of future operating results is difficult or impossible.

Clinical Product Development

TELINTRA, our current drug product candidate in clinical development, is a small molecule glutathione analog inhibitor of the enzyme
glutathione S-transferase P1-1. We are developing TELINTRA for the treatment of blood disorders associated with low blood cell levels, such as neutropenia or anemia. In May 2008, we initiated a Phase 2 clinical trial of TELINTRA tablets for the
treatment of patients with MDS and completed enrollment of 86 patients in 2009. In June 2010, we announced positive results of our Phase 2 clinical trial of TELINTRA tablets for the treatment of patients with MDS and plan to present the data at a
scientific conference later this year. In the second quarter of 2009, we initiated a Phase 2 randomized study in SCN to determine the effect of TELINTRA tablets on absolute neutrophil count in patients with this disease. The trial for SCN is
intended to enroll a total of 20 patients. In the fourth quarter of 2009, we initiated a Phase 1 dose-ranging study of TELINTRA tablets in combination with Lenalidomide in patients with MDS. We expect to enroll up to 30 patients for this study.

TELCYTA, our first product candidate, is a small molecule cancer drug product candidate designed to be activated in cancer
cells. TELCYTA has shown clinical antitumor activity alone and in combination with standard chemotherapeutic agents in multiple Phase 2 clinical trials in refractory or resistant ovarian, non-small cell lung, breast and colorectal cancer. In
addition, TELCYTA demonstrated clinical activity in two Phase 2 trials in combination regimens as first line treatment in patients with Stage IIIb or IV non-small cell lung cancer.

We have completed multiple Phase 1, Phase 2 and Phase 3 clinical trials with TELCYTA alone and in combination with standard chemotherapy
drugs. These trials were conducted in refractory ovarian and non-small cell lung cancer. The Phase 3 trials did not achieve their primary endpoints. At the ASCO meeting in June 2009, we reported results of the trial comparing treatment with Doxil
alone and TELCYTA plus Doxil in platinum refractory ovarian cancer in which a sub-set of patients with platinum refractory disease demonstrated a statistically significant improvement in progression free survival when treated with the combination
containing TELCYTA as compared to Doxil alone. In addition, we published in a peer reviewed publication the results of a Phase 2 multicenter trial treating previously untreated lung cancer patients for the first time with carboplatin, paclitaxel and
TELCYTA followed by TELCYTA maintenance that demonstrated a statistically significant improvement in the group of patient undergoing TELCYTA maintenance. In May 2010, we initiated an investigator led study at a single site of TELCYTA in patients
with Refractory or Relapsed Mantle Cell lymphoma, Diffuse Large B Cell Lymphoma, and Multiple Myeloma. Enrollment for this study is expected to range between 18 to 48 patients based on the number of responses observed. We also plan to seek a
partnership with a pharmaceutical or biotechnology company to advance the development and potential commercialization of TELCYTA.

Preclinical Drug Product Development

TLK60404Aurora Kinase/VEGFR Inhibitors

We have a small molecule compound inhibiting both Aurora kinase and VEGFR kinase. Aurora kinase is a signaling enzyme whose function is
required for cancer cell division, while VEGF plays a key role in tumor blood vessel formation, ensuring an adequate supply of nutrients to support tumor growth. The lead compounds of our first dual inhibitor program met a development milestone in
August 2008 by demonstrating anticancer activity in preclinical models of human colon cancer and human leukemia. These lead compounds prevented tumor growth in preclinical models of human colon cancer and human leukemia by inhibiting both Aurora
kinase and VEGFR kinase. Our data support the concept that dual inhibition of Aurora kinase and VEGFR kinase represents a promising approach for anticancer therapy. A development drug product candidate, TLK60404, has been selected. We are conducting
the required preclinical safety studies that if successful may support the potential filing of an IND application with the FDA.

TLK60357Antimitotic Agent

Using our TRAP technology, we have discovered TLK60357, a novel, potent small molecule inhibitor of cell division. TLK60357 inhibits the
formation of microtubules that are necessary for cancer cell growth leading to persistent cancer cell block and subsequent cell death at the G2/M cell cycle. This compound demonstrates potent broad-spectrum anticancer activity against a number of
human cancer cells. This compound also displays oral efficacy in multiple, standard preclinical models of cancer. TLK60357 is currently being evaluated in preclinical safety studies.

TLK60596  VEGFR Inhibitor

TLK60596 is a small-molecule dual inhibitor of VEGFR1 and VEGFR2 kinase. VEGFR1/2 kinases are known to mediate the formation of new blood
vessels in human cancers allowing them to grow. In standard animal models of human colon cancer, oral administration of TLK60596 significantly reduced tumor growth. TLK60596 is undergoing further preclinical assessment.

TLK58747Cytotoxic Small Molecule

TLK58747 is a novel metabolically activated cytotoxic small molecule. TLK58747 induces apoptosis and G2/M, or cell division, cell cycle
arrest in a broad array of human cancer cell lines including those not expressing GST P1-1. It has shown significant antitumor activity in human breast, pancreatic, brain and colon tumors in preclinical models of human cancer when administered
either orally or by injection.

Other

We discovered all of our drug product candidates using our proprietary technology, TRAP, which we believe enables the rapid and efficient
discovery of small molecule drug product candidates. We expect to enter into collaborative arrangements with third parties, such as contract research organizations for clinical trials, development, manufacturing, regulatory approvals or
commercialization of some of our products, particularly outside North America, or in disease areas requiring larger and longer clinical trials than cancer.

Nasdaq Stock Listing Compliance

On September 19, 2008, we received notification from Nasdaq informing us that the bid price for our common stock had closed below the
minimum $1.00 per share requirement for continued inclusion on the Nasdaq Global Market under Nasdaq Marketplace Rule 5550(a)(2) and giving us 180 days to regain compliance. Nasdaq subsequently implemented temporary suspensions of the minimum bid
price requirement, allowing us until January 4, 2010 to regain compliance. Effective January 7, 2010, we transferred the listing of

our common stock from the Nasdaq Global Market to the Nasdaq Capital Market. In accordance with Listing Rule 5810(c)(3)(A), we were provided with an additional 180-day period, or until
July 6, 2010, to regain compliance with the minimum bid price requirement. On April 22, 2010, we received notification from Nasdaq that we have regained compliance with the minimum bid price requirement. Since May 20, 2010, the bid
price for our common stock had again fluctuated below the levels required by Nasdaq rules. On July 21, 2010, we received notification from Nasdaq informing us that the bid price for our common stock had closed below the minimum $1.00 per share
requirement for continued inclusion on the Nasdaq Capital Market and that we have 180 calendar days, or until January 18, 2011, to regain compliance.

UBS Purchase Rights and Loan

On November 10, 2008, we entered into an agreement with UBS AG and with its affiliates, or UBS, whereby we received rights, or the
Right, to sell all our auction rate securities, or ARS, held in our UBS account at par value to UBS at any time during a two-year period beginning on June 30, 2010 and ending on July 2, 2012. If we do not exercise the Right, the ARS will
continue to accrue and pay interest as determined by the auction process or the terms specified in the prospectus of the ARS if the auction process fails. If the Right is not exercised on or before July 2, 2012, it will expire and UBS will have
no further obligation to buy our ARS. UBS is also granted the right to purchase or sell our ARS at any time after acceptance of the Agreement until July 2, 2012, so long as we receive par value for the ARS. The Right is a nontransferable
security registered with the SEC.

In connection with our acceptance of the offer to enter into the agreement, UBS has made
available to us no net cost loans for up to 75% of the market value of our ARS, where interest payable on the loan does not exceed interest earned on our ARS. The loan is secured by our ARS. On December 31, 2008, we borrowed $8
million from UBS in accordance with such a secured, no net cost demand facility. On June 10, 2009 and February 12, 2010, UBS elected to repurchase a portion of our ARS under the Rights Agreement at par value of $4.9 million and
$4.0 million, respectively. Proceeds from sales of our ARS were applied to the repayments of the credit line, which was paid in full in February 2010. For the six months ended June 30, 2010, interest paid on the loan was approximately $6,000
which was offset entirely by interest earned on the pledged securities.

On July 1, 2010, we exercised the Right to sell
all our remaining ARS to UBS under the Rights Agreement at par value of $9.8 million. Proceeds from the sale are re-invested in US government agencies and we no longer have any ARS investments in our portfolio. To-date, we have not incurred any
losses on our ARS investments, total par value of $18.7 million, as a result of the Rights Agreement with UBS.

Critical
Accounting Policies and Significant Judgments and Estimates

Our managements discussion and analysis of our
financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements requires us to
make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported revenues and expenses during the
reporting periods. On an on-going basis, we evaluate our estimates and judgments related to revenue recognition and clinical development costs. We base our estimates on historical experience and on various other factors that we believe are
reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these
estimates under different assumptions or conditions.

There has been no material change in our critical accounting policies
and significant judgments and estimates as described in our Annual Report on Form 10-K for the year ended December 31, 2009.

Use of Estimates

In preparing our financial statements to conform with GAAP, we make estimates and assumptions that affect the amounts reported in our
financial statements and accompanying notes. Actual results may differ from these estimates.

Results of Operations

Revenues

We did not record any revenues in 2009 and currently do not expect to record any revenues in 2010. Future non-product revenues, if any,
will depend upon the extent to which we enter into new collaborative research agreements and the amounts of payments relating to such agreements.

Research and Development Expenses

Research and development expenses for the three months ended June 30, 2010 and 2009 were $2.8 million and $3.0 million. Research and
development expenses for the six months ended June 30, 2010 and 2009 were $5.6 million and $7.0 million. Our research and development activities consist primarily of drug development, clinical supply manufacturing, clinical activities,
discovery research, screening and identification of product candidates and preclinical studies. We group these activities into two major categories: research and preclinical and clinical development.

The approximate costs associated with research and preclinical and clinical development activities were as follows:

The decrease of 7%, or $214,000, in research and development expenses for the three months ended
June 30, 2010 compared to the same period in 2009 was principally due to the following:



| |  |  | decreased costs of approximately $316,000 associated with headcount reduction as a result of our restructuring in 2009 and reduced research activities;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | decreased expenses of approximately $289,000 for TLK58747-Cytotoxic Small Molecule pre-clinical development program which was partially offset by a
$26,000 increase in pre-clinical expenses related to TLK60404-Aurora Kinase;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | offset by increased clinical development expenses of approximately $107,000 for our ongoing Phase 2 TELINTRA tablets clinical studies; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in addition, the three months ended June 30, 2009 included approximately $267,000 reduction in accrued clinical trials expenses as a result of
final close-out of clinical sites for completed clinical studies while there were no such adjustments in 2010.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The decrease of 20%, or $1.4 million, in research and development expenses for the six months ended June 30, 2010 compared to the
same period in 2009 was principally due to the following:



| |  |  | decreased costs of approximately $1.7 million in connection with headcount reduction as a result of our restructuring in 2009 and reduced research
activities;

We
expect total research and development expenditures to decrease in 2010 as we complete our Phase 2 TELINTRA tablets for MDS clinical trial and continue other smaller ongoing TELINTRA and TELCYTA clinical trials as well as advancing new drug
candidates into the clinic.

|--- | -----------------------------------------------------------------------------------------------------------

The largest component of our total operating expenses is our on-going investment in our research and development activities and, in
particular, the clinical development of our product candidate pipeline. The process of conducting the clinical research necessary to obtain FDA approval is costly and time consuming. Current FDA requirements for a new human drug to be marketed in
the United States include:



| |  |  | the successful conclusion of preclinical laboratory and animal tests, if appropriate, to gain preliminary information on the products safety;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | filing with the FDA of an IND, to conduct initial human clinical trials for drug candidates;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | the successful completion of adequate and well-controlled human clinical trials to establish the safety and efficacy of the product candidate; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | filing by company and acceptance and approval by the FDA of a New Drug Application, or NDA, for a product candidate to allow commercial distribution of
the drug.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------

In view of the factors mentioned above, we consider the active management and development of our
clinical pipeline to be crucial to our long-term success. The actual probability of success for each candidate and clinical program may be impacted by a variety of factors, including, among others, the quality of the candidate, the validity of the
target and disease indication, early clinical data, investment in the program, competition, manufacturing capability and commercial viability. Due to these and other factors, it is difficult to give accurate guidance on the anticipated proportion of
our research and development investments or the future cash inflows from these programs.

The decrease in general and administrative expenses of 31%, or $1.0 million, for the three
months ended June 30, 2010 compared to the same period in 2009 was primarily due to a decrease of $433,000 in headcount and corporate administrative expenses, decreased stock-based compensation expense of approximately $177,000 as a result of
higher fair value options fully vested in 2009 and a decrease of $392,000 in legal and professional service expenses.

The
decrease in general and administrative expenses of 22%, or $1.3 million, in the six months ended June 30, 2010 compared to the same period in 2009 was primarily due a decrease of $515,000 in headcount and corporate administrative expenses,
decreased stock-based compensation expense of approximately $284,000 as a result of higher fair value options fully vested in 2009 and a decrease of $532,000 in legal and professional service expenses.

We expect 2010 general and administrative expenses to be lower than the 2009 spending level as we undertake efforts to control expenses.

Employee stock-based compensation expenses for
research and development for the three and six months ended June 30, 2010 compared with the same periods in 2009 were higher principally due to cancellations of unvested options related to the reduction in force in February 2009. The decreases
in employee stock-based compensation expense for general and administrative for the three and six months ended June 30, 2010 compared with the same periods in 2009 were primarily due to higher fair value options fully vested in 2009.

Restructuring Costs

In February 2009, we implemented a restructuring plan and reduced our workforce by 37 positions and recorded charges of approximately
$83,000 and $951, 000 for the three months and six months ended June 30, 2009. We paid $750,000 in the quarter ended March 31, 2009 and $111,000 in the quarter ended June 30, 2009 as severance, payroll taxes and other personnel
related costs. There were no restructuring costs recorded for the three and six months ended June 30, 2010.

The decrease in interest and other income, net of approximately $594,000 for the three
months ended June 30, 2010 compared to the same period in 2009 was due primarily to a decrease of $100,000 in investment income resulting from lower investment cash balances, a net change of $165,000 in fair values of our ARS and the UBS ARS
Rights and a gain of $329,000 on the sale of computer and laboratory equipment recorded in 2009.

The decrease in interest and
other income, net of approximately $602,000 for the six months ended June 30, 2010 compared to the same period in 2009 was due primarily to a decrease of $230,000 in investment income resulting from lower investment cash balances, a gain of
$330,000 on the sale of computer and laboratory equipment recorded in 2009 and a change of $42,000 in fair value of ARS.

Interest expenses for the periods reported were solely for interest payments on our UBS loan. There was no interest expense for the three
months ended June 30, 2010 and the decrease of approximately $54,000 for the six months ended June 30, 2010 compared to the same period in 2009 was due to the full payment of our UBS loan balance in February 2010.

Sources and Uses
of Cash. Due to the significant research and development expenditures and the lack of any approved products to generate revenue, we have not been profitable and have generated operating losses since we incorporated in 1988. As such, we have
funded our research and development operations through the sale of equity securities, non-equity payments from corporate partners, interest earned on investments and equipment lease and loan financings. At June 30, 2010, we had available cash,
cash equivalents, investments and restricted investments of $30.8 million. Our cash and investment balances are held in a variety of interest-bearing instruments including obligations of U.S. government agencies, auction rate securities and money
market accounts. 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.

Cash Flows from Operating Activities. Cash used in operations for the six months ended June 30, 2010 was $8.9 million
compared with $13.7 million for the same period in 2009. Net loss of $10.3 million in 2010 included non-cash charges of $1.1 million for stock-based compensation, $186,000 for depreciation and amortization and $111,000 for the decrease in the fair
value of our ARS which were partially offset by a $111,000 reduction in value of the put option associated with the UBS ARS Rights. Cash used in operations was further impacted by an $186,000 reduction in accrued liabilities related primarily to
payments made during the six months ended June 30, 2010 for 2009 audit and tax services and clinical trials site costs. Cash used in operations was partially offset by a decrease of $98,000 in other receivables due to lower investment interest
receivables and an approximately $106,000 increase in accounts payable. Operating cash outflows for the same

##### Table of Contents

period in 2009 resulted primarily from a net loss of $13.4 million which included non-cash charges of $1.3 million for stock-based compensation, $314,000 for depreciation and amortization and
$5.2 million for the reduction in value of the put option associated with the UBS ARS Right and were partially offset by a $5.2 million gain in the fair value of our ARS and a $335,000 gain on the disposal of property and equipment. Cash used in
operations was further impacted by a $1.3 million reduction in accrued clinical trials related primarily to the completion of our ASSIST 1, 2, 3 and 5 Phase 3 clinical trials and a $772,000 decrease in accounts payable.

Cash Flows from Investing Activities. Cash provided by investing activities for the six months ended June 30, 2010 was $5.5
million compared with cash used in investing activities of $30.7 million for the same period in 2009. Cash provided in the six months ended June 30, 2010 was primarily from $15 million in investment maturities and $4.2 million in investment
sales which included a $4.0 million sale of our ARS to UBS on February 12, 2010 and was partially offset by the purchase of available-for-sale investments of $13.8 million. We had $5,000 in proceeds from the sale of property and equipment and
no capital expenditures for the six months ended June 30, 2010. Cash used in the same period in 2009 was primarily from $33.4 million in purchases of available-for-sale investments and were partially offset by $2.0 million in investment
maturities, $224,000 in investment sales and a $4.9 million sale of our ARS to UBS on June 20, 2009 which was applied to the repayment of our loan. We had $480,000 in proceeds from the sale of property and equipment and no capital expenditures
for the six months ended June 30, 2009.

Cash Flows from Financing Activities. Cash used in financing activities
for the six months ended June 30, 2010 was approximately $3.1 million compared with cash provided by financing activities of $23,000 for the same period in 2009. Cash used in financing activities for the six months ended June 30, 2010 was
primarily due to $3.1 million payment of our remaining UBS loan balance on February 16, 2010 and was offset by $34,000 in proceeds from stock purchases under our employee stock purchase plan. Financing activities for the same period in 2009
comprised $23,000 in proceeds from stock purchases under our employee stock purchase plan.

Working Capital. Working
capital decreased to $30.5 million at June 30, 2010 from $39.2 million at December 31, 2009. The decrease in working capital was primarily due to our use of cash for our clinical studies, pre-clinical programs and operating expenses.

We believe our existing cash resources will be sufficient to satisfy our current operating plan until the end of 2011.
Changes in our research and development plans or other changes affecting our operating expenses may affect actual future consumption of existing cash resources as well. In any event, we will require substantial additional financing to fund our
operations in the future. We may seek to raise any necessary additional funds through equity or debt financings, collaborative arrangements with corporate partners or other sources. To the extent that we raise additional capital by issuing equity
securities, our stockholders may experience dilution. Debt financing may subject us to restrictive covenants that may adversely affect our operations. To the extent that we raise additional capital through licensing arrangements or arrangements with
collaborative partners, we may be required to relinquish, on terms that are not favorable to us, rights to some of our technologies or product candidates that we would otherwise seek to develop or commercialize ourselves. Our future capital uses and
requirements depend on numerous factors, including the following:



| |  |  | the progress and success of preclinical studies and clinical trials of our product candidates;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | the progress and number of research programs in development;
| | - |  | ------------------------------------------------------------



| |  |  | the costs associated with conducting Phase 2 clinical trials;

| |  |  | the costs and timing of obtaining regulatory approvals;

| |  |  | our ability to establish, and the scope of, any new collaborations;
| | - |  | -------------------------------------------------------------------



| |  |  | our ability to meet the milestones identified in our collaborative agreements that trigger payments;

| | - |  | -------------------------------------------------------------------------------------------------------

We currently have no commitments for any additional financings. If we need to raise
additional money to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to raise additional funds when needed, we may not be able to continue development of our product candidates, or we could be
required to delay, scale back or eliminate some or all of our research and development programs.

We also have a contractual obligation under the terms of our manufacturing supply agreement with AMRI wherein we are obligated to
purchase a majority of our United States requirements for the active ingredient in TELCYTA for a number of years. However, we currently do not have any requirements for the active ingredient. We have agreed on a pricing schedule for such supply,
which will be subject to future renegotiation after a defined time period.

We have no material off-balance sheet arrangements
as defined in Regulation S-K 303(a)(4)(ii).



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

The following discussion about our market risk exposure involves forward-looking statements. We do not use or hold derivative financial
instruments; however we are exposed to market risk related to changes in interest rates and market conditions.

Our investment
policy is to manage our marketable securities portfolio to preserve principal and liquidity while maximizing the return on the investment portfolio. To minimize the exposure due to adverse shifts in interest rates, we maintain investments of shorter
maturities. Our marketable securities portfolio is primarily invested in corporate debt securities and commercial papers with an average maturity of under one year and a minimum investment grade rating of A or A-1 or better to minimize credit risk.
Although changes in interest rates may affect the fair value of the marketable securities portfolio and cause unrealized gains or losses, such gains or losses would not be realized unless the investments were sold prior to maturity. Through our
money managers, we maintain risk management control systems to monitor interest rate risk. The risk management control systems use analytical techniques, including sensitivity analysis. We have operated primarily in the United States and all funding
activities with our collaborators to date have been made in U.S. dollars. Accordingly, we do not have any exposure to foreign currency rate fluctuations.

The table below presents the principal amounts and weighted-average interest rates by year of stated maturity for our investment
portfolio:

Trading securities are comprised of corporate securities, student loans and municipal notes
investments with an auction reset feature in the form of auction rate certificates and auction preferred stock, collectively known as ARS, held in our account with UBS. We earn interest on the ARS even though these investments are not liquid and
their carrying amounts are impaired due to the adverse change in the debt market. In November 2008, we entered into an agreement with UBS whereby we received the Right to sell all our ARS held in our UBS account at par value to UBS at any time
during a two-year period beginning on June 30, 2010 and ending on July 2, 2012. We intend to exercise this right and recover par value of the ARS. The value of the Right largely offset the decline in fair value of the ARS. However,
UBS obligations under the Right are not secured by its assets and do not require UBS to obtain any financing to support its performance obligations under the Right. UBS has disclaimed any assurance that it will have sufficient financial
resources to satisfy its obligations under the Right. If UBS has insufficient funding to buy back the ARS and the auction process continues to fail, then we may incur further losses on the carrying value of the ARS. On December 31, 2008, we
entered into a loan agreement with UBS and drew down $8 million with our ARS pledged as collateral. The loan is treated as a no net cost loan as defined in the agreement, meaning that the loan will bear interest at a rate equal to the
average rate of interest paid or deemed paid to us on the pledged ARS such that the interest cost, net of interest received by us on the pledged ARS, will be zero. On June 10, 2009 and February 12, 2010, UBS elected to repurchase a portion
of our ARS under the Rights Agreement at par value of $4.9 million and $4.0 million, respectively. Proceeds from sales of our ARS were applied to the repayments of the credit line which was paid in full as of June 30, 2010. On July 1,
2010, we exercised the Right and sold all our remaining ARS to UBS under the Rights Agreement at par value of $9.8 million. As such, we no longer have any ARS investments in our portfolio. Other than the UBS loan, there were no material changes to
our market exposure risk since December 31, 2009.



|Item 4. | Controls and Procedures.
|------- | ------------------------

Evaluation of disclosure controls and procedures. Based on our managements evaluation (with the participation of our chief
executive officer and chief financial officer), our chief executive officer and chief financial officer have concluded that, subject to limitations described below, our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)
under the Securities Exchange Act of 1934, as amended), were effective as of June 30, 2010.

Changes in internal
control over financial reporting. There were no changes in our internal controls over financial reporting during the quarter ended June 30, 2010 that have materially affected, or are reasonably likely to materially affect, our internal
controls over financial reporting.

Limitations on the effectiveness of controls. A control system, no matter how well
conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of 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 report, that our disclosure controls and procedures were sufficiently effective to provide
reasonable assurance that the objectives of our disclosure control system were met.

PART II. OTHER INFORMATION



|Item 1A. | Risk Factors.
|-------- | -------------

Included below is a description of risk factors related to our business to enable readers to assess, and be appropriately apprised of,
many of the risks and uncertainties applicable to the forward-looking statements made in this Quarterly Report on Form 10-Q. The risks and uncertainties set forth below are not all of the risks and uncertainties facing our business, but we do
believe that they reflect the more important ones. You should carefully consider these risk factors as each of these risks could adversely affect our business, operating results and financial condition. Given these risks and uncertainties, you are
cautioned not to place undue reliance on forward-looking statements.

The risk factors described in Part I,
Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2009, as filed with the SEC on March 2, 2010, are set forth below. These risk factors have not substantively changed, except for those identified by asterisk
and restated below.

If we are unable to raise adequate funds in the future, we will not be able to continue to fund our operations,
research programs, preclinical testing and clinical trials to develop and manufacture our drug product candidates.*

The
process of carrying out the development of our own unpartnered product candidates to later stages of development and developing other research programs to the stage that they may be partnered to a pharmaceutical or biotechnology company will require
significant additional expenditures, including the expenses associated with preclinical testing, clinical trials and obtaining regulatory approval. We believe that our existing cash and investment securities will be sufficient to support our current
operating plan until the end of 2011. Unanticipated changes in our research and development plans or other changes affecting our operating expenses may affect actual future consumption of existing cash resources as well. In any event, we will
require substantial additional financing to fund our operations in the future. We do not know whether additional financing will be available when needed or that, if available, we will be able to obtain financing on terms favorable to our
stockholders. In addition, the recent tightening of credit markets and concerns regarding the availability of credit, particularly in the United States, may also have negatively impacted our ability to raise additional capital to fund our business.
As of June 30, 2010, our accumulated deficit was $513.9 million, and we expect to incur capital outlays and operating expenditures for the next several years as we continue our clinical, research and development activities. The extent of any
actual increase in operating or capital spending will depend in part on the clinical success of our product candidates. If we fail to raise adequate funds on terms acceptable to us, if at all, we will not be able to continue to fund our operations,
research programs, preclinical testing, clinical trials and manufacturing efforts.

We have a history of net losses, which we expect to
continue for the next several years. We will never be profitable unless we develop, and obtain regulatory approval and market acceptance of, our product candidates.*

To date, we have not obtained regulatory approval for the commercial sale of any products, and we have not received any revenue from the
commercial sale of products. Due to the significant research and development expenditures required to develop our TRAP technology and identify new product candidates, and the lack of any products to generate revenue, we have not been profitable and
have incurred operating losses since we were incorporated in 1988. As of June 30, 2010, we had an accumulated deficit of $513.9 million. We expect to incur losses for the next several years as we continue our research and development activities
and incur significant clinical testing and drug supply manufacturing costs. We do not anticipate that we will generate product revenue for several years. Our losses, among other things, have caused and will cause our stockholders equity and
working capital to decrease. We expect that this trend will continue until we develop, and obtain regulatory approval and market acceptance of, our product candidates, if at all. We may never generate product revenue sufficient to become profitable.

Both of our most advanced drug product candidates, TELINTRA and TELCYTA, are in clinical development. If
clinical trials of our product candidates are delayed or unsuccessful, or if we are unable to complete the preclinical development of our other preclinical product candidates, our business may suffer. *

Preclinical testing and clinical trials are long, expensive and uncertain processes. It may take us or our collaborators several years to
complete this testing, and failure can occur at any stage of the process. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of clinical trials do not
necessarily predict final results. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after promising results in earlier clinical trials. To
obtain regulatory approvals, we must, among other requirements, complete carefully controlled and well-designed clinical trials demonstrating that a particular drug is safe and effective for the applicable disease.

In January 2007, we completed a Phase 2 clinical trial of the intravenous formulation of TELINTRA in MDS, a form of pre-leukemia, to
evaluate safety, pharmacokinetics, pharmacodynamics and efficacy. In February 2006, we initiated a Phase 1-2a clinical trial of a tablet formulation of TELINTRA in MDS and announced final data at the American Society of Hematology meeting in
December 2007. In May 2008, we initiated a Phase 2 clinical trial of TELINTRA tablets for the treatment of patients with MDS. In April 2009, we initiated another randomized Phase 2 clinical trial in Severe Chronic Neutropenia, or SCN; and in
November 2009, we initiated a Phase 1 Dose-Ranging Study of TELINTRA tablets in combination with Lenalidomide in patients with MDS. Our success depends in part on our ability to continue clinical development of TELINTRA.

TELCYTA has been evaluated in multiple Phase 1, Phase 2 and Phase 3 clinical trials. On June 3, 2007, we announced that the Phase 3
trials did not achieve their primary endpoints. Subsequently, on June 4, 2007, the FDA initiated a full clinical hold for TELCYTA. On June 15, 2007, the FDA converted the full clinical hold to a partial hold, thereby enabling patients that
had been enrolled in the trials the opportunity to continue to receive study treatments, including TELCYTA in combination with chemotherapy, subject to re-consenting procedures. In October 2007, after completing their review of the detailed safety
and other information we submitted, the FDA removed the partial hold, permitting the resumption of our TELCYTA clinical development. As a result of these circumstances, the FDA requires that we conduct additional studies of TELCYTA to complete
clinical development. In May 2010, we initiated an investigator led study at a single site of TELCYTA in patients with Refractory or Relapsed Mantle Cell lymphoma, Diffuse Large B Cell Lymphoma, and Multiple Myeloma.

Our success depends in part on our ability to continue clinical development of TELINTRA and TELCYTA. If we do not have sufficient capital
required to conduct additional studies or if the data on future clinical trials are not positive, we may not be able to continue clinical development on TELINTRA or TELCYTA and our business will suffer.

We rely on third-party clinical investigators to conduct our clinical trials and, as a result, we may face additional delays outside our
control. We have in the past engaged contract research organizations, or CROs, to facilitate the administration of our Phase 3 clinical trials of TELCYTA. Dependence on a CRO subjects us to a number of risks. We may not be able to control the amount
and timing of resources the CRO may devote to our clinical trials. Should the CRO fail to administer our Phase 3 clinical trials properly and on a timely basis, regulatory approval, development and commercialization of TELCYTA will be delayed.

We do not know whether we will begin planned clinical trials on time or whether we will complete any of our on-going clinical
trials on schedule, if at all. Clinical trials can be delayed for a variety of other reasons, including delays in clinical testing, obtaining regulatory approval to commence a study, 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 and delays in recruiting subjects to participate in a study. Even if we are able to complete
such clinical trials, we do not know whether any such trials will result in marketable products. Typically, there is a high rate of failure for product candidates in preclinical and clinical trials. We do not anticipate that any of our product
candidates will reach the market for at least the next several years.

##### Table of Contents

Delays in clinical testing can also materially impact our product candidates
development costs. If we experience delays in clinical testing or approvals, our product candidates 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 additional 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
significantly impaired or delayed.

If we do not find collaborators for our product candidates, we may have to reduce or delay our rate of
product development and/or increase our expenditures.

Our strategy to develop, manufacture and commercialize our products
includes entering into relationships with pharmaceutical companies to advance certain programs and reduce our expenditures with respect to such programs. Our product candidates will target highly competitive therapeutic markets in which we have
limited experience and expertise. If we are unable to develop this expertise ourselves, we will need to enter into agreements with one or more biotechnology or pharmaceutical companies to provide us with the necessary resources and experience for
the development and commercialization of products in these markets. In particular, we intend to seek a partnership with a pharmaceutical or biotechnology company to further advance the development and commercialization of TELCYTA. There are a
limited number of companies with the resources necessary to develop our future products commercially, and we may be unable to attract any of these firms. The current credit and financial market conditions could also impact our ability to find a
collaborator for our development programs. A company that has entered into a collaboration agreement with one of our competitors may choose not to enter into a collaboration agreement with us. We may not be able to negotiate a collaboration
agreement on acceptable terms or at all. If we are not able to establish collaborative arrangements, we may have to reduce or delay further development of some of our programs and/or increase our expenditures and undertake the development activities
at our own expense. If we elect to increase our expenditures to fund our development programs, we will need to obtain additional capital, which may not be available on acceptable terms or at all.

In addition, there have been a significant number of recent business combinations among biotechnology and pharmaceutical companies that
have reduced the number of potential future collaborators that would be willing to enter into a collaboration agreement with us. If business combinations involving potential collaborators continue to occur, our ability to find a collaborative
partner could be diminished, which could result in the termination or delay in one or more of our product candidate development programs.

We will depend on collaborative arrangements to complete the development and commercialization of some of our product candidates. These collaborative
arrangements may place the development of our product candidates outside of our control, may require us to relinquish important rights or may otherwise not be on terms favorable to us.

We expect to enter into collaborative arrangements with third parties for clinical trials, development, manufacturing, regulatory
approvals or commercialization of some of our product candidates. Dependence on collaborative arrangements will subject us to a number of risks. We may not be able to control the amount and timing of resources our collaborative partners may devote
to the product candidates. Our collaborative partners may experience financial difficulties. Should a collaborative partner fail to develop or commercialize a compound or product candidate to which it has rights from us, we may not receive any
future milestone payments and will not receive any royalties for that compound or product candidate. Business combinations or significant changes in a collaborative partners business strategy may also adversely affect a partners
willingness or ability to complete its obligations under an arrangement. If we fail to enter into additional collaborative agreements on favorable terms, our business, financial condition and results of operations could be materially adversely
affected.

Some of our collaborations are for early stage programs and allow partners significant discretion in electing
whether to pursue any of the planned activities. We do not anticipate significant revenues to result from these relationships until the collaborator has advanced product candidates into clinical trials, which will not occur for several years, if at
all. These arrangements are subject to numerous risks, including the right of the collaboration partner to control the timing of the research and development efforts, the advancement of lead



28

##### Table of Contents

product candidates to clinical trials and the commercialization of product candidates. In addition, a collaborative partner could independently move forward with a competing lead candidate
developed either independently or in collaboration with others, including our competitors.

Our ability to publicly or privately sell
equity securities and the liquidity of our common stock could be adversely affected if we are delisted from Nasdaq or if we are unable to transfer our listing to another stock market.*

On September 19, 2008, we received a letter from the Nasdaq Listing Qualifications Department indicating that, for 30 consecutive
business days, the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Global Market under Nasdaq Marketplace Rule 5550(a)(2). The letter also stated that in accordance with
Nasdaq Marketplace Rule 5810(c)(3)(A), we were given 180 calendar days to regain compliance with this listing requirement, which may be accomplished if the bid price of our common stock closes at $1.00 per share or more for a minimum of 10
consecutive business days. Subsequently, Nasdaq implemented temporary suspensions of the minimum bid price requirement, allowing us until January 4, 2010 to regain compliance. Effective January 7, 2010, we transferred the listing of our
common stock from the Nasdaq Global Market to the Nasdaq Capital Market. In accordance with Listing Rule 5810(c)(3)(A), we were provided an additional 180-day period, or until July 6, 2010, to regain compliance with the minimum bid price
requirement. On April 22, 2010, we received notice from Nasdaq that we have regained compliance with the minimum bid price requirement. Since May 20, 2010, the bid price for our common stock had again fluctuated below the levels required
by Nasdaq rules. On July 21, 2010, we received notification from Nasdaq informing us that the bid price for our common stock had closed below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Capital Market and we
have 180 calendar days, or until January 18, 2011, to regain compliance.

Delisting from Nasdaq could adversely affect
our ability to raise additional financing through the public or private sale of equity securities, would significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our common stock.
Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.

We believe that our ability to compete depends, in part, on our ability to use our proprietary TRAP technology to discover new pharmaceutical
products.

TRAP, our proprietary drug discovery technology, is a relatively new drug discovery method that uses a protein
panel of approximately 20 proteins selected for their distinct patterns of interacting with small molecules. This panel may lack essential types of interactions that we have not yet identified, which may result in our inability to identify active
compounds that we could potentially develop into commercially viable drugs.

Raising additional capital by issuing securities or through
collaboration and licensing arrangements may cause dilution to existing stockholders or require us to relinquish rights to our technologies or product candidates.

We may seek to raise additional funds through equity or debt financings, collaborative arrangements with corporate partners or other
sources. To the extent that we raise additional capital by issuing equity securities, our stockholders may experience dilution. To the extent that we raise additional capital through licensing arrangements or arrangements with collaborative
partners, we may be required to relinquish, on terms that are not favorable to us, rights to some of our technologies or product candidates that we would otherwise seek to develop or commercialize ourselves.

It may be difficult for us to retain our current employees and identify, hire and retain future employees.

Our future success depends in part upon our ability to attract and retain highly skilled personnel. Several factors could make it
difficult for us to achieve this. Competition among numerous companies, academic and other research institutions for skilled personnel and experienced scientists may be intense and turnover rates high. The cost of living in the San Francisco Bay
Area is high compared to other parts of the country, which



29



---

##### Table of Contents

could adversely affect our ability to compete for qualified personnel and increase our costs. Because of this competitive environment, we have encountered and may continue to encounter increasing
difficulty attracting qualified personnel, particularly if our operations expand and the demand for these professionals increases.

In addition, we may have difficulty attracting and retaining personnel as a result of having carried out three workforce reductions since
2007, the most recent of which was completed in February 2009. We cannot assure you that future reductions or adjustments of our workforce will not be made or that issues, such as voluntary departures by some employees, associated with such
reductions will not recur. These circumstances could significantly impede the achievement of our business objectives.

If our competitors
develop and market products that are more effective than our product candidates or any products that we may develop, or obtain marketing approval before we do, our commercial opportunity will be reduced or eliminated.

The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Some
of the drugs that we are attempting to develop will have to compete with existing therapies. In addition, a large number of companies are pursuing the development of pharmaceuticals that target the same diseases and conditions that we are targeting.
We face competition from pharmaceutical and biotechnology companies in the United States and abroad. Our competitors may develop new screening technologies and may utilize discovery techniques or partner with collaborators in order to develop
products more rapidly or successfully than we or our collaborators are able to do.

Many of our competitors, particularly
large pharmaceutical companies, have substantially greater financial, technical and human resources than we do. These organizations also compete with us to attract qualified personnel and parties for acquisitions, joint ventures, licensing
arrangements or other collaborations. In addition, academic institutions, government agencies and other public and private organizations conducting research may seek patent protection with respect to potentially competing products or technologies
and may establish exclusive collaborative or licensing relationships with our competitors.

Our competitors may succeed in
developing technologies and drugs that are more effective, better tolerated or less costly than any which are being developed by us or which would render our technology and potential drugs obsolete and noncompetitive. In addition, our competitors
may succeed in obtaining FDA or other regulatory approvals for product candidates more rapidly than us or our collaborators. Any drugs resulting from our research and development efforts, or from our joint efforts with our existing or future
collaborative partners, may not be able to compete successfully with our competitors existing products or product candidates under development or may not obtain regulatory approval in the United States or elsewhere.

If we do not obtain regulatory approval to market products in the United States and foreign countries, we or our collaborators will not be permitted
to commercialize our product candidates.

Even if we are able to achieve success in our preclinical testing, we, or our
collaborators, must provide the FDA and foreign regulatory authorities with clinical data that demonstrate the safety and efficacy of our product candidates in humans before they can be approved for commercial sale. Failure to obtain regulatory
approval will prevent commercialization of our product candidates.

The pharmaceutical industry is subject to stringent
regulation by a wide range of regulatory authorities. We cannot predict whether regulatory clearance will be obtained for any product candidate that we are developing or hope to develop. A pharmaceutical product cannot be marketed in the United
States until it has completed rigorous preclinical testing and clinical trials and an extensive regulatory clearance process implemented by the FDA. Satisfaction of regulatory requirements typically takes many years and depends on the type,
complexity and novelty of the product candidate and requires the expenditure of substantial resources. Of particular significance are the requirements covering research and development, testing, manufacturing, quality control, labeling and promotion
of drugs for human use.

##### Table of Contents

Before commencing clinical trials in humans, we, or our collaborators, must submit and
receive approval from the FDA of an IND application. We must comply with FDA Good Laboratory Practices regulations in our preclinical studies. Clinical trials are subject to oversight by Institutional Review Boards, or IRBs, of
participating clinical sites and the FDA and:



| |  |  | must be conducted in conformance with the FDA regulations;
| | - |  | ----------------------------------------------------------



| |  |  | must meet requirements for IRB approval;
| | - |  | ----------------------------------------



| |  |  | must meet requirements for informed consent;
| | - |  | --------------------------------------------



| |  |  | must meet requirements for Good Clinical Practices;
| | - |  | ---------------------------------------------------



| |  |  | may require large numbers of participants; and
| | - |  | ----------------------------------------------



| |  |  | may be suspended by us, our collaborators or the FDA at any time if it is believed that the subjects participating in these trials are being exposed to
unacceptable health risks or if the FDA finds deficiencies in the IND application or the conduct of these trials. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the
IRBs requirements, or may impose other conditions.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Before receiving FDA clearance to market a product
candidate, we, or our collaborators must demonstrate that the product candidate is safe and effective in the patient population that will be treated. Negative or inconclusive results or adverse medical events during a clinical trial could cause a
clinical trial to be repeated, a program to be terminated and could delay approval. We typically rely on third-party clinical investigators to conduct our clinical trials and other third-party organizations to perform data collection and analysis.
As a result, we may face additional delaying factors outside our control. In addition, we may encounter delays or rejections based upon additional government regulation from future legislation or administrative action or changes in FDA policy or
interpretation 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. We have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approval.

If regulatory clearance of a product candidate is granted, this clearance will be limited to those disease states and conditions for
which the product candidate is demonstrated through clinical trials to be safe and efficacious, which could limit our market opportunity. Furthermore, product approvals, once granted, may be withdrawn if problems occur after initial marketing. We
cannot ensure that any product candidate 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 clearance. Regulatory
clearance may also contain requirements for costly post-marketing testing and surveillance to monitor the safety and efficacy of the product candidate. If problems occur after initial marketing, such as the discovery of previously unknown problems
with our product candidates, including unanticipated adverse events or adverse events of unanticipated severity or frequency, or manufacturer or manufacturing issues, marketing approval can be withdrawn.

Outside the United States, the ability to market a product depends on receiving a marketing authorization from the appropriate regulatory
authorities. Most foreign regulatory approval processes include all of the risks associated with FDA clearance described above and some may include additional risks.

As our product programs advance, we may need to hire additional scientific and management personnel. Our research and development efforts will be
seriously jeopardized if we are unable to attract and retain key personnel.

Our success depends in part on the continued
contributions of our principal management and scientific personnel and on our ability to develop and maintain important relationships with leading academic institutions, scientists and companies in the face of intense competition for such personnel.
As we plan for additional advanced clinical trials, including Phase 2 and Phase 3, we may also need to expand our clinical development personnel. If we lose the services of Dr. Wick or any of our other key personnel, our research and
development efforts could be seriously and adversely affected. We have generally entered into consulting or other agreements with our scientific and clinical collaborators and advisors. We do not carry key person insurance that covers Dr. Wick
or any of our other key employees.

##### Table of Contents

If we or our licensees cannot obtain and defend our respective intellectual property rights, or if our
product candidates, technologies or any products that we may develop are found to infringe patents of third parties, we could become involved in lengthy and costly legal proceedings that could adversely affect our business.

Our success will depend in a large part on our own and our licensees ability to obtain and defend patents for each partys
respective technologies and the compounds and other products, if any, resulting from the application of these technologies. The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and
factual questions. As a result, the degree of future protection for our proprietary rights is uncertain, and we cannot assure you that:



| |  |  | we were the first to make the inventions covered by each of our pending patent applications;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | we were the first to file patent applications for these inventions;
| | - |  | -------------------------------------------------------------------



| |  |  | others will not independently develop similar or alternative technologies or duplicate any of our technologies;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | any of our pending patent applications will result in issued patents;
| | - |  | ---------------------------------------------------------------------



| |  |  | any patents issued to us or our collaborators will provide a basis for commercially viable products, will provide us with any competitive advantages or
will not be challenged by third parties;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any of our issued patents will be valid or enforceable; or
| | - |  | ----------------------------------------------------------



| |  |  | we will develop additional proprietary technologies that are patentable.
| | - |  | ------------------------------------------------------------------------

Accordingly, we cannot predict the breadth of claims allowed in our or other companies patents.

For TRAP, we hold patents in the United States that will expire between 2014 and 2015. For TELCYTA, we hold compound patents in the
United States and internationally that will expire in 2013 and 2014. For TELINTRA, we hold compound patents in the United States and internationally that will expire in 2014. We can generally apply for patent term extensions on the patents for
TELCYTA and TELINTRA when and if marketing approvals for these compounds are obtained in the relevant countries. In foreign countries, these extensions are available only if approval is obtained before the patent expires, but in the United States,
extensions are available even if approval is obtained after the patent would expire normally through a system of interim extensions until approval.

Our success will also depend, in part, on our ability to operate without infringing the intellectual property rights of others. We cannot
assure you that our activities will not infringe patents owned by others. To date, we have not received any communications with the owners of related patents alleging that our activities infringe their patents. However, if our product candidates,
technologies or any products that we may develop are found to infringe patents issued to third parties, the manufacture, use and sale of any products that we may develop could be enjoined, and we could be required to pay substantial damages. In
addition, we may be required to obtain licenses to patents or other proprietary rights of third parties. We cannot assure you that any licenses required under any such patents or proprietary rights would be made available on terms acceptable to us,
if at all. Failure to obtain such licenses could negatively affect our business.

Others may have filed and in the future may
file patent applications covering small molecules or therapeutic products that are similar to ours. We cannot assure you that our patent applications will have priority over patent applications filed by others. Any legal action against us or our
collaborators claiming damages and seeking to enjoin commercial activities relating to the affected products and processes could, in addition to subjecting us to potential liability for damages, require us or our collaborators to obtain a license to
continue to manufacture or market the affected products and processes. We cannot predict whether we, or our collaborators, would prevail in any of these actions or that any license required under any of these patents would be made available on
commercially acceptable terms, if at all. We believe that there may be significant litigation in the industry regarding patent and other intellectual property rights. If we become involved in litigation, it could consume a substantial portion of our
managerial and financial resources, and we may not be successful in any such litigation.



32

##### Table of Contents

In addition, we could incur substantial costs and use of our key employees time and
efforts in litigation if we are required to defend against patent suits brought by third parties or if we initiate these suits, and we cannot predict whether we would be able to prevail in any of these suits.

Furthermore, some of our patents and intellectual property rights are owned jointly by us and our collaborators. While there are legal
and contractual restraints on the rights of these joint owners, they may use these patents and other intellectual property in ways that may harm our business. We may not be able to prevent this type of use.

We also rely on trade secrets to protect technology, including aspects of our TRAP technology, where we believe patent protection is not
appropriate or obtainable. However, trade secrets are difficult to protect. While we require employees, academic collaborators and consultants to enter into confidentiality agreements, we may not be able to adequately protect our trade secrets or
other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of such information. If the identity of specific proteins or other elements of our TRAP technology become known, our competitive
advantage in drug discovery could be reduced.

Many of our collaborators and scientific advisors have publication and other
rights to certain information and data gained from their collaborations and research with us. Any publication or other use could limit our ability to secure intellectual property rights or impair any competitive advantage that we may possess or
realize by maintaining the confidentiality of that information or data.

If we are unable to enter into or maintain existing contracts with
third parties to manufacture our product candidates or any products that we may develop in sufficient quantities and at an acceptable cost, clinical development of product candidates could be delayed and we may be unable to meet demand for any
products that we may develop and lose potential revenue.

We do not currently operate manufacturing facilities for
clinical or commercial production of our product candidates. We expect to continue to rely on third parties for the manufacture of our product candidates and any products that we may develop. We currently lack the resources and capability to
manufacture any of our product candidates on a clinical scale or any products that we may develop on a commercial scale. As a result, we will be dependent on corporate partners, licensees or other third parties for the manufacturing of clinical and
commercial scale quantities of our product candidates and any products that we may develop. Our product candidates and any products that we may develop may be in competition with other product candidates and products for access to these
manufacturing facilities. For this and other reasons, our collaborators or third parties may not be able to manufacture our product candidates and products in a cost effective or timely manner. While we currently possess sufficient inventory of
TELCYTA and TELINTRA that are stored in multiple locations and an additional, substantial quantity of the active ingredient in TELCYTA, if these inventories are lost or damaged, the clinical development of our product candidates or their submission
for regulatory approval could be delayed, and our ability to deliver any products that we may develop on a timely basis could be impaired or precluded.

We are currently dependent on a single source of supply of the active ingredient in TELCYTA, AMRI. We currently depend upon two sources
for the drug product manufacture of TELCYTA.

We presently depend upon one source of supply, Isochem, for clinical quantities
of the active ingredient in TELINTRA. We currently depend upon one source, Patheon, for the manufacture of TELINTRA tablets. While we are evaluating potential alternative sources of these materials, we have no such alternative sources that are
immediately available.

If manufacturing is not performed in a timely manner, if our suppliers fail to perform or if our
relationships with our suppliers or manufacturers should terminate, our clinical trials and commercialization of TELCYTA and TELINTRA could be delayed. We may not be able to enter into or maintain any necessary third-party manufacturing arrangements
on acceptable terms, if at all. Our current dependence upon others for the manufacture of our product candidates and our anticipated dependence upon others for the manufacture of any products that we may develop may adversely affect our future
profit margins and our ability to commercialize any products that we may develop on a timely and competitive basis.

Working capital constraints may force us to delay our efforts to develop certain product candidates in
favor of developing others, which may prevent us from commercializing all product candidates as quickly as possible.

Because we have limited resources, and because research and development is an expensive process, we must regularly assess the most
efficient allocation of our research and development budget. As a result, we may have to prioritize development candidates and may not be able to fully realize the value of some of our product candidates in a timely manner, as they will be delayed
in reaching the market, if at all.

If product liability lawsuits are successfully brought against us, we may incur substantial liabilities
and may be required to limit commercialization of our product candidates and any products that we may develop.

The
testing and marketing of medical products entail an inherent risk of product liability. Although we are not aware of any historical or anticipated product liability claims or specific causes for concern, if we cannot successfully defend ourselves
against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates and any products that we may develop. In addition, product liability claims may also result in withdrawal of
clinical trial volunteers, injury to our reputation and decreased demand for any products that we may commercialize. We currently carry product liability insurance that covers our clinical trials up to a $10 million annual aggregate limit. We will
need to increase the amount of coverage if and when we have a product that is commercially available. If we are unable to obtain sufficient product liability insurance at an acceptable cost, potential product liability claims could prevent or
inhibit the commercialization of any products that we may develop, alone or with corporate partners.

If we use biological and hazardous
materials in a manner that causes injury, we may be liable for damages.*

Our research and development activities involve
the controlled use of potentially harmful biological materials, hazardous materials, chemicals and various radioactive compounds, and are subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of
these materials and specified waste products. We cannot eliminate the risk of accidental contamination or injury from the use, storage, handling or disposal of these materials. We currently have insurance applying to various types of biological and
pollution exposures for a total amount of $125,000 in coverage. However, in the event of contamination or injury, we could be held liable for damages that result from our use of hazardous materials, and any liability could significantly exceed our
coverage and resources.

We have implemented anti-takeover provisions which could discourage or prevent a takeover, even if an acquisition
would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management.

Provisions of our amended and restated certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more
difficult for a third-party to acquire us, even if doing so would be beneficial to our stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it
more difficult for stockholders to replace members of our board of directors. Because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt by our stockholders to
replace current members of our management team. These provisions include:



| |  |  | establishing a classified board of directors requiring that members of the board be elected in different years, which lengthens the time needed to
elect a new majority of the board;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | authorizing the issuance of blank check preferred stock that could be issued by our board of directors to increase the number of
outstanding shares or change the balance of voting control and thwart a takeover attempt;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | prohibiting cumulative voting in the election of directors, which would otherwise allow for less than a majority of stockholders to elect director
candidates;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limiting the ability of stockholders to call special meetings of the stockholders;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | prohibiting stockholder action by written consent and requiring all stockholder actions to be taken at a meeting of our stockholders; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establishing 90 to 120 day advance notice requirements for nominations for election to the board of directors and for proposing matters that can be
acted upon by stockholders at stockholder meetings.

We adopted a stockholder rights plan that may discourage, delay or
prevent a merger or acquisition that is beneficial to our stockholders.

In November 2001, our board of directors adopted
a stockholder rights plan that may have the effect of discouraging, delaying or preventing a merger or acquisition that is beneficial to our stockholders by diluting the ability of a potential acquiror to acquire us. Under the plan, except under
certain circumstances, if a person or group acquires 20% or more of our outstanding common stock, or 10 business days after a person or group commences or announces a tender or exchange offer for 20% or more of our outstanding common stock, that
person or group becomes an Acquiring Person, and the rights (except those rights held by the Acquiring Person) would generally become exercisable for shares of our common stock at a discount. In May 2006, we amended the stockholder
rights plan to exclude Eastbourne Capital Management, L.L.C. and certain related persons and entities, collectively Eastbourne, from the definition of Acquiring Person so long as neither Eastbourne nor its affiliates or associates, either
individually or in the aggregate, becomes the beneficial owner of 25% or more of the common stock then outstanding. On December 11, 2006, the plan was further amended to increase this threshold to 30% with respect to Eastbourne. Because the
potential acquirors rights would not become exercisable for our shares of common stock at a discount, the potential acquiror would suffer substantial dilution and may lose its ability to acquire us. In addition, the existence of the plan
itself may deter a potential acquiror from acquiring us. As a result, either by operation of the plan or by its potential deterrent effect, mergers and acquisitions of us that our stockholders may consider in their best interests may not occur.

Substantial future sales of our common stock by us or by our existing stockholders could cause our stock price to fall.

Additional equity financings or other share issuances by us, including shares issued in connection with strategic alliances and corporate
partnering transactions, could adversely affect the market price of our common stock. Sales by existing stockholders 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 market price of our common stock to drop. Substantially all of our outstanding shares of common stock were freely tradable and, in limited cases, subject to certain volume, notice and manner of sale restrictions under Rule 144 of the Securities
Act of 1933.

If we do not progress in our programs as anticipated, our stock price could decrease.

For planning purposes, we estimate the timing of a variety of clinical, regulatory and other milestones, such as when a certain product
candidate will enter clinical development, when a clinical trial will be completed or when an application for regulatory approval will be filed. Our estimates are based on present facts and a variety of assumptions. Many of the underlying
assumptions are outside of our control. If milestones are not achieved when we estimated that they would be, investors could be disappointed, and our stock price may decrease.

Our stock price may be volatile, you may not be able to resell your shares at or above your purchase price.*

Our stock prices and the market prices for securities of biotechnology companies in general have been highly volatile, with recent
significant price and volume fluctuations, and may continue to be highly volatile in the future. For example, our stock price dropped by 71% on the day following the announcement in December 2006 that the preliminary top-line results of our first
three Phase 3 trials did not meet primary end-points. During the six months ended June 30, 2010, our common stock traded between $0.66 and $1.49, and on June 30, 2010, our common stock closed at $0.78. You may not be able to sell your
shares quickly or at the market

price if we are delisted from Nasdaq or if we are unable to transfer listing to another stock market, or if trading in our stock is not active or the volume is low. The following factors, in
addition to other risk factors described in this section, may have a significant impact on the market price of our common stock, some of which are beyond our control:



| |  |  | developments regarding, or the results of, our clinical trials;
| | - |  | ---------------------------------------------------------------



| |  |  | announcements of technological innovations or new commercial products by our competitors or us;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | developments concerning proprietary rights, including patents;
| | - |  | --------------------------------------------------------------



| |  |  | developments concerning our collaborations;
| | - |  | -------------------------------------------



| |  |  | publicity regarding actual or potential medical results relating to products under development by our competitors or us;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | regulatory developments in the United States and foreign countries;
| | - |  | -------------------------------------------------------------------



| |  |  | litigation;
| | - |  | -----------



| |  |  | economic and other external factors or other disaster or crisis; or
| | - |  | -------------------------------------------------------------------



| |  |  | period-to-period fluctuations in our financial results.
| | - |  | -------------------------------------------------------

We have been, and in the future may be, subject to securities class action lawsuits and shareholder derivative actions. These, and potential similar
or related litigation, could result in substantial damages and may divert managements time and attention from our business.

Beginning on June 6, 2007, a series of putative securities class action lawsuits were commenced in the United States District Courts
for the Southern District of New York and the Northern District of California, naming as defendants Telik, Inc. and certain of our current officers, one of whom is also a director. The complaints filed in the Southern District of New York, which
were consolidated and amended in 2007, also name as defendants the underwriters of our November 2003 and/or January 2005 stock offerings. Plaintiffs in the Northern District of California subsequently voluntarily dismissed their complaints without
prejudice. The complaints alleged violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 arising out of the issuance of allegedly false and misleading statements about our business and prospects, including the efficacy,
safety and likelihood of success of our product candidate TELCYTA. The allegations of the consolidated amended complaint were similar, but more narrow than the original complaints. Plaintiffs sought unspecified damages and injunctive relief on
behalf of purchasers of our common stock during the period between March 27, 2003 and June 4, 2007, including purchasers in the January 2005 stock offering.

In January 2008, the parties to the securities class action reached an agreement in principle to settle the claims, the settlement to be
funded primarily by proceeds from insurance. In October 2008, the court entered a final judgment approving the settlement and resolving all class claims.

We may in the future be the target of securities class actions or shareholder derivative claims. Any such actions or claims could result
in substantial damages and may divert managements time and attention from our business.
