NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


(unaudited)





1.    Basis of Presentation and Significant Accounting Policies





Basis of Presentation





The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting
principles for interim financial information. The information as of March 31, 2002 and for the three months ended March 31, 2001 and March 31, 2002 includes all adjustments (consisting only of normal recurring adjustments) that the management of
Maxygen, Inc. (Maxygen or the Company) believes necessary for fair presentation of the results for the periods presented.





Results for any interim period are not necessarily indicative of results for any future interim period or for the entire year. The accompanying condensed consolidated financial statements should be read in conjunction with the financial
statements and notes thereto included in the Companys Report on Form 10-K for the year ended December 31, 2001.





Principles of Consolidation





The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.





Revenue Recognition





Non-refundable up-front payments received in connection with research and development collaboration agreements, including technology advancement funding that is intended for the development of the Companys core
technology, are deferred and recognized on a straight-line basis over the relevant periods specified in the agreement, generally the research term.





Revenue related to collaborative research with the Companys corporate collaborators is recognized as research services are performed over the related funding periods for each contract. Under these agreements, the Company is required
to perform research and development activities as specified in each respective agreement. The payments received under each respective agreement are not refundable and are generally based on a contractual cost per full-time equivalent employee
working on the project. Research and development expenses under the collaborative research agreements approximate or exceed the research funding revenue recognized under such agreements over the term of the respective agreements. Deferred revenue
may result when the Company does not incur the required level of effort during a specific period in comparison to funds received under the respective contracts. Payments received related to substantive, at-risk incentive milestones, if any, are
recognized as revenue upon achievement of the incentive milestone event because the Company has no future performance obligations related to the payment. Incentive milestone payments are triggered either by the results of the Companys research
efforts or by events external to the Company, such as regulatory approval to market a product. Royalties, if any, are recognized when earned.





The
Company was awarded grants from the Defense Advanced Research Projects Agency, National Institute of Standards and Technology-Advanced Technology Program and the U.S. Agency for International Development for various research and development
projects. The terms of these grant agreements are three years with various termination dates, the last of which is September 2004 for existing agreements. Revenue related to grant agreements is recognized as related research and development expenses
are incurred.





Net Loss Per Share





Basic and
diluted net loss per common share are presented in conformity with the Statement of Financial Accounting Standards No. 128, Earnings per Share (SFAS 128), for all periods presented. In accordance with




6




---

##### Table of Contents




SFAS 128, basic and diluted net loss per share has been computed using the weighted-average number of shares of common
stock outstanding during the period, less shares subject to repurchase.





The following table presents the calculation of basic and diluted net loss per
share (in thousands, except share and per share data):

The Company has excluded all outstanding stock options, outstanding warrants and shares subject to
repurchase from the calculation of diluted loss per common share because all such securities are antidilutive for all applicable periods presented. The total number of shares excluded from the calculations of diluted net loss per share, prior to
application of the treasury stock method for options, was 6,362,000 at March 31, 2001 and 8,519,000 at March 31, 2002. Such securities, had they been dilutive, would have been included in the computations of diluted net loss per share along with
restricted common stock subject to the Companys right of repurchase.





Comprehensive Income (Loss)





Comprehensive income (loss) is primarily comprised of net unrealized gains or losses on available-for-sale securities and foreign currency translation adjustments. Comprehensive
income (loss) and its components for the three month periods ended March 31, 2001 and 2002 were as follows (in thousands):

Recent Accounting Pronouncements





In October 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (Statement 144), which addresses
financial accounting and reporting for the impairment or disposal of long-lived assets and supersedes Statement 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, and the accounting and reporting
provisions of APB Opinion No. 30, Reporting the Results of Operations for a disposal of a segment of a business. The Company adopted Statement 144 on January 1, 2002, and has determined that the Statement does not have a significant impact to the
Companys financial position and results of operations.





2.    Investments





Management determines the appropriate classification of debt securities at the time of purchase and reevaluates such designation as of each balance sheet date. The
Companys debt securities are classified as available-for-sale and are carried at estimated fair value in cash equivalents and investments. Unrealized gains and losses are reported as accumulated other comprehensive income (loss) in
stockholders equity. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income. Realized gains and losses on
available-for-sale securities and declines in value deemed to be other-than temporary, if any, are included in interest income and expense. The cost of securities sold is based on the specific identification method. Interest and dividends on
securities classified as available-for-sale are included in interest income. The Companys cash equivalents and investments as of March 31, 2002 are as follows (in thousands):

3.     Intangible Assets





In July 2001, the Financing Accounting Standard Board issued Statement of Financial Accounting Standards (referred to as SFAS) No. 141, Business Combinations and SFAS No. 142, Goodwill and
Other Intangible Assets. SFAS 141 specifies criteria that intangible assets acquired in a purchase business combination must meet to be recognized and reported apart from goodwill, noting that any purchase price allocable to an assembled




8




---

##### Table of Contents




workforce may not be accounted for separately. SFAS 142 requires, among other things, that the assembled workforce be
reclassified to goodwill and that goodwill (including assembled workforce) and intangible assets with indefinite lives no longer be amortized, but instead be tested for impairment at least annually in accordance with SFAS 142. The Company has no
intangible assets with indefinite lives. SFAS 142 also requires that intangible assets with definite useful lives be amortized over their respective useful lives to their estimated residual values, and reviewed for impairment in accordance with SFAS
144, Accounting for the Impairment or Disposal of Long-Lived Assets. The Company adopted the provisions of SFAS 141 and SFAS 142 effective January 1, 2002.





SFAS 141 provides that, upon adoption of SFAS 142, the Company is required to evaluate existing intangible assets and goodwill that were acquired in a purchase business combination prior to June 30, 2001, and make
necessary reclassifications to conform with the new criteria in SFAS 141. As a result, the Company reclassified assembled workforce with a net carrying value of $378,000 to goodwill on January 1, 2002.





Upon adoption of SFAS 142, the Company reassessed the useful lives and residual values of all intangible assets (excluding goodwill and assembled workforce) acquired in purchase
business combinations. No adjustments to amortization periods were necessary.





In connection with the transitional goodwill impairment evaluation, SFAS
142 adoption requires the Company to assess whether there is an indication that goodwill is impaired as of January 1, 2002. To accomplish this, the Company will identify its reporting units as of January 1, 2002. The Company will determine the
carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets to these reporting units as of January 1, 2002. The Company has up to six months from January 1, 2002 to complete
this first step of determining the fair value of each reporting unit and compare it to the reporting units carrying amount. To the extent a reporting units carrying amount exceeds its fair value, an indication exists that the reporting
unit may be impaired and the Company must perform the second step of the transitional impairment test. In the second step, the Company must compare the implied fair value of the reporting units goodwill, determined by allocating the reporting
units fair value to all of its assets (recognized and unrecognized) and liabilities in a manner similar to purchase price allocation in accordance wth SFAS 141, to its carrying amount, both of which will be measured as of Janaury 1, 2002. This
second step must be completed as soon as possible, but no later that December 31, 2002. The Company will recognize any transition impairment loss as the cumulative effect of a change in accounting principle. The Company is in the process of
completing the first step of the transitional goodwill impairment evaluation





In addition, the Company must perform an impairment test at least annually.
Any impairment loss from the annual test will be recognized as a part of operations.





A reconciliation of reported net loss to adjusted net loss, as if
SFAS 142 had been implemented as of January 1, 2002, is as follows (in thousands, except per share data):

4.    Derivatives and Financial Instruments





The Company addresses certain financial exposures through a program of risk management that includes the use of derivative financial instruments. To date the Company has only
entered into foreign currency forward exchange contracts generally expiring within one year to reduce the effects of fluctuating foreign currency exchange rates on forecasted cash requirements.





All derivatives are recognized on the balance sheet at their fair value. The Company has designated its derivatives as foreign currency cash flow hedges. Changes in the fair value of derivatives that are
highly effective as, and that are designated and qualify as, foreign currency cash flow hedges are recorded in other comprehensive income until the associated hedged transaction impacts earnings.





The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. The Company
also formally assesses, both at the hedges inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. When it is
determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Company discontinues hedge accounting prospectively.





The purpose of the hedging activities is to minimize the effect of foreign exchange rate movements on the cash flows related to the Companys funding of Maxygen ApS. All foreign currency contracts are denominated
in Danish kroner. At March 31, 2001, the Company had foreign currency contracts outstanding in the form of forward exchange contracts totaling $7.5 million.





5.    Collaborative Agreements





Cargill Dow LLC





In March 2002, Codexis, Inc., a wholly-owned subsidiary of the Company, established a collaboration with Cargill Dow LLC, to research and develop a novel process for the production of lactic acid. The goal
of the collaboration is to further improve Cargill Dows novel low-cost process for the production of lactic acid from natural sugars derived from annually renewable resources, such as corn. Under the terms of the collaboration, Codexis will
receive technology access payments and full research funding, and may receive research and commercialization milestones. Codexis will also receive royalties on any sales of products manufactured using its technologies. Cargill Dow has worldwide
commercialization rights for products generated from any improved production process.

6.    Litigation





In December 2001 a lawsuit was filed in the U.S. District Court for the Southern District of New York against Maxygen, Inc., certain officers of the Company, and certain underwriters of the Companys initial
public offering and secondary public offering of common stock. The lawsuit, which alleges claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and Section 10(b) of the Securities Exchange Act of 1934, is among the so-called
laddering cases that have been commenced against a number of companies that had public offerings of securities prior to December 2000. The complaint has been consolidated with other laddering claims in a proceeding styled In re Initial Public
Offering Securities Litigation, No. 21 MC 92 (SAS), pending before the Honorable Shira A. Scheindlin. In early 2002 the Company was served with the complaint, and in April 2002 the Company was served with an amended complaint.





The complaint seeks damages in an unspecified amount. The Company believes that the claims alleged against the Company and its officers are without merit and intends
to defend the action vigorously. The Company does not expect the outcome of this matter to have a material effect on its financial position or results from operations.





7.    Segment Information





The Company has four reportable segments: human therapeutics,
agriculture, chemicals and all other. The Company has determined its reportable operating segments based upon how the business is managed and operated. The accounting policies of the segments described above are the same as those described in Note 1
in this report and in the Companys annual report on Form 10-K. The Company does not identify or allocate assets by operating segment, nor does management evaluate segments on these criteria.





Segment Earnings





The Company evaluates the performance of its operating
segments without considering the effects of net interest expense and income, amortization of intangibles and stock compensation expense, all which are managed by corporate headquarters. Corporate administrative costs including depreciation and
amortization expense are allocated based on headcount.

Forward-Looking Statements





This report contains forward-looking statements within the meaning of federal securities laws that relate to future events or our future financial performance. In some cases, you can identify forward-looking
statements by terminology such as may, can, will, should, expect, plan, anticipate, believe, estimate, predict,
intend, potential or continue or the negative of these terms or other comparable terminology. Risks and uncertainties and the occurrence of other events could cause actual results to differ materially from these

ITEM 2


MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS





Overview





Maxygen was founded in May 1996 and began operations in March 1997. To date, we have
generated revenues from research collaborations with agriculture, pharmaceutical, petroleum, and chemical companies and from government grants. We have strategic collaborations with leading companies including: Aventis Pasteur in novel vaccines;
Celltech in antibodies; InterMune in next generation interferon gamma therapies; Lundbeck in interferon beta therapies for central nervous system diseases and multiple sclerosis; ALK-Abelló in allergy; the International AIDS Vaccine
Initiative (IAVI) in HIV; Pfizer and DSM in pharmaceutical manufacturing; and Shearwater Corporation in protein pharmaceutical PEGylation technologies. Additionally, we have a range of other strategic alliances in industrial applications, as well as
funding from U.S. government organizations including from the Defense Advanced Research Projects Agency, the National Institute of Standards and Technology-Advanced Technology Program and the U.S. Agency for International Development.





Revenue under strategic alliances and government grants increased from $24.5 million in 2000, to $30.5 million in 2001 and was $9.3 million in the three months ended
March 31, 2002. Revenues may fluctuate from period to period and there can be no assurance that these collaborations will continue for their initial term or beyond.





We have incurred significant losses since our inception. As of March 31, 2002, our accumulated deficit was $137.7 million and total stockholders equity was $246.8 million. We have invested heavily in
establishing our proprietary technologies. These investments have contributed to the increases in operating expenses from $70.4 million in 2000 (excluding $29.0 million of acquired in-process research and development expense) to $88.4 million in
2001, to $20.5 million in the three months ended March 31, 2002. Our total headcount increased from 252 employees at the end of 2000 to 305 employees at the end of 2001. As of March 31, 2002 we had 305 employees, of whom 85% were engaged in research
and development. We expect to incur additional operating losses over at least the next several years as we continue to expand our research and development efforts and infrastructure.





Critical Accounting Policies and Estimates





General





The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States that require us to make estimates and assumptions. We believe the
following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

##### Table of Contents

Goodwill and Intangible Impairment








In connection with the Maxygen ApS acquisition, we allocated $26.2 million to goodwill and other intangible assets and amortize the intangible assets using the straight-line method over the assets estimated useful
lives of three years, the term of expected benefit. We believed this term was reasonable given that Maxygen ApS was a development stage entity and its technology was at an early stage of development and was yet unproven.





In June 2001, the Financing Accounting Standard Board issued Statement of Financial Accounting Standards No. 141, Business Combinations and No. 142, Goodwill and Other
Intangible Assets, effective for the fiscal years beginning after December 15, 2001. Under the new rules, goodwill will no longer be amortized but will be subject to annual impairment tests in accordance with Statement No. 142. Other intangible
assets will continue to be amortized over the useful lives.





We have applied the new rules on accounting for goodwill and other intangible assets during
the first quarter of 2002. Application of the nonamortization provisions of Statement No. 142 is expected to result in a decrease in net loss of $7.6 million in 2002 and $4.6 million in 2003. During the second quarter of 2002, we will perform the
first of the required impairment tests of goodwill and indefinite-lived intangible assets as of January 1, 2002 and have not yet determined what the effect of these tests will be on the earnings and our financial position.





In January 2002, we adopted Statement of Financing Accounting Standards No. 144 Accounting for the Impairment or Disposal of Long-Lived Assets (Statement 144), which addresses
financial accounting and reporting for the impairment or disposal of long-lived assets. We evaluate our intangible assets for impairment whenever events or changes in circumstances indicate that such assets are impaired or the estimated useful lives
are no longer appropriate. If indicators of impairment exist, we will review our long-lived assets for impairment based on estimated future discounted cash flows attributable to the assets and other factors to determine the fair value of the
respective assets. In the event such cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their estimated fair values.





Source of Revenue and Revenue Recognition Policy





We recognize revenues from research collaboration
agreements as earned upon achievement of the performance requirements of the agreements. Our existing corporate collaboration agreements generally provide for research funding for a specified number of full time equivalent researchers working in
defined research programs. Revenue related to these payments is earned as the related research work is performed. In addition, these collaborators may make technology advancement payments that are intended to fund development of our core technology,
as opposed to a defined research program. These payments are recognized ratably over the applicable funding period. Payments received that are related to future performance are deferred and recognized as revenue as the performance requirements are
achieved. As of March 31, 2002, we have deferred revenues of approximately $12.6 million.





Revenue related to performance milestones is recognized based
upon the achievement of the milestones, as defined in the respective agreements. Payments received related to substantive, at-risk incentive milestones, if any, are recognized as revenue upon achievement of the incentive milestone event because we
have no future performance obligations related to the payment and we judge the event to be the culmination of a separate earnings process. Incentive milestone payments are triggered either by the results of our research efforts or by events external
to Maxygen, such as regulatory approval to market a product. Royalties are recorded as earned in accordance with the contract terms when third party results are reliably measured and collectibility is reasonably assured.





Revenue related to grant agreements with various government agencies is recognized as the related research and development expenses are incurred, and when these research and
development expenses are within the prior approved funding amounts. Certain grant agreements provide an option for the government to audit the amount of research and development expenses, both direct and indirect, that have been submitted to the
government agency for reimbursement. We believe the overhead rates we used to calculate our indirect research and development expenses are within the contractual guidelines of allowable costs and are reasonable estimates of our indirect expenses
incurred through the term of the agreement.

##### Table of Contents




Our sources of potential revenue for the next several years are likely to be license, research, technology advancement
and milestone payments under existing and possible future collaborative arrangements, government research grants, and royalties from our collaborators based upon revenues received from any products commercialized under those agreements.





Deferred Compensation





Deferred compensation for
options granted to employees has been determined as the difference between the deemed fair market value for financial reporting purposes of our common stock on the date the applicable options were granted and the exercise price. Deferred
compensation for options granted to consultants has been determined in accordance with Statement of Financial Accounting Standards No. 123 and EITF 96-18 as the fair value of the equity instruments issued. Compensation for related options granted to
consultants is periodically remeasured as the underlying options vest.





In connection with the grant of stock options to employees before our initial
public offering, we recorded deferred stock compensation of approximately $2.4 million in 1998 and $19.5 million in 1999. These amounts were initially recorded as a component of stockholders equity and are being amortized as charges to
operations over the vesting period of the options using a graded vesting method. We recognized stock compensation expense related to the deferred compensation amortization on these option grants of $646,000 and $428,000 for the three months ended
March 31, 2001 and 2002, respectively, which were included in research and development expense, and $667,000 and $571,000 for the three months ended March 31, 2001 and 2002, respectively, which were included in general and administrative expense.





Stock compensation expense in connection with the grant of stock options to consultants for the three months ended March 31, 2001 and 2002 were
insignificant.





In connection with the Maxygen ApS acquisition in August 2000, stock options were granted in exchange for outstanding warrants to
purchase Maxygen ApS securities. In connection with this exchange we recorded aggregate deferred compensation totaling $1.5 million. This amount is being amortized over the remaining vesting period of the options, of which $179,000 was expensed in
both the three months ended March 31, 2001 and 2002. For the shares exchanged that had a right of repurchase, deferred compensation of $13.1 million was recorded. This amount is being amortized to expense over a three-year graded vesting period. A
total of $2.0 million and $920,000 was recognized as expense for the three months ended March 31, 2001 and 2002, respectively.





Results of Operations





Revenues





Our total
revenues increased from $6.9 million in the three months ended March 31, 2001, to $9.3 million for the three months ended March 31, 2002. The increase in collaborative research and development revenue was due to additional strategic alliances and
the expansion of existing alliances. The decline in grant revenue reflects the expiration of three government grants that began in late 1998 and early 1999. We expect our total revenues to increase in the remainder of 2002 as new projects are
initiated under existing collaboration agreements and as new collaboration arrangements are consummated.





Revenues for each operating segment are derived
from our research collaboration agreements and government research grants and are categorized based on the industry of the product or technology under development.

Research and Development Expenses





We have entered into a number of research and development collaborations to perform research for our collaborators. The major collaborative agreements all have similar contractual terms. The agreements generally require us to devote a
specified number of full-time equivalent employees to the research efforts over defined terms ranging from three to five years.





We do not track fully
burdened research and development costs or capital expenditures by project. However, we estimate based on full-time equivalent (FTE) effort, that approximately 50% and 49% for the three months ended March 31, 2001 and 2002, respectively, of research
and development efforts (as measured in hours incurred) were undertaken for collaborative projects funded by our collaborators and government grants, and approximately 50% and 51% for the three months ended March 31, 2001 and 2002, respectively, of
research effort was on our own internally funded research projects. Due to the nature of our research and our dependence on our collaborative partners to commercialize the results of the research, we cannot predict with any certainty whether any
particular collaboration or research effort will ultimately result in a commercial product and therefore whether we will receive future milestone payments or royalty payments under our various collaborations.





Most of our human therapeutic, agriculture and chemical product development programs are at an early stage and may not result in any marketed products. Product candidates that
may appear promising at early stages of development may not reach the market for a number of reasons. Human therapeutic product candidates may be found ineffective or cause harmful side effects during clinical trials, may take longer to pass through
clinical trials than had been anticipated, may fail to receive necessary regulatory approvals and may prove impracticable to manufacture in commercial quantities at reasonable costs and with acceptable quality. Chemical and agricultural product
candidates may be found ineffective, may cause undesirable side effects or may prove impracticable to manufacture in commercial quantities at reasonable costs and with acceptable quality. Furthermore, it is uncertain which of our internally
developed product candidates will be subject to future collaborative arrangements. The participation of a collaborative partner may accelerate the time to completion and reduce the cost to us of a product candidate or it may delay the time and
increase the cost to us due to the alteration of our existing strategy. The risks and uncertainties associated with our research and development projects are discussed more fully in the section of this report titled Risk Factors That May
Affect Results of Operations and Financial Condition. Because of these risks and uncertainties, we cannot predict when or whether we will successfully complete the development of our product candidates or the ultimate product development cost
in any particular case.





Our research and development expenses consist primarily of salaries and other personnel-related expenses, facility costs,
supplies and depreciation of facilities and laboratory equipment. Research and development expenses increased from $15.6 million for the three months ended March 31, 2001 to $16.6 million for the three months ended March 31, 2002. Also included in
research and development expenses is stock compensation expense of $2.9 million for the three months ended March 31, 2001 and $1.6 million for the three months ended March 31, 2002. The increase in total research and development expense is primarily
due to our accelerated efforts in all aspects of research and development as well as investments in our technology platforms and in the development of product candidates. The decrease in stock compensation expense is primarily a result of lower
amortization expense related to deferred compensation for the shares exchanged that had a right of repurchase in connection with the Maxygen ApS acquisition in August 2000. This amount is being amortized to expense over a three year graded vesting
period.





Research and development expenses represented 225% of total revenues for the three months ended March 31, 2001 and 177% for the three months
ended March 31, 2002. The decrease between quarters is primarily due to growth in our total revenue between periods.





We expect research and development
cost to increase during the remainder of 2002 as new projects are initiated under existing collaboration agreements and as new collaboration arrangements are consummated. We expect to continue to devote substantial resources to research and
development, and we expect that research and development expenses will continue to increase in absolute dollars for at least the next several years.





General and Administrative Expenses





Our general and administrative expenses consist primarily of personnel costs
for finance, human resources, business development, legal and general management, as well as professional expenses, such as legal and

##### Table of Contents

accounting. General and administrative expenses decreased from $4.2 million for the three months ended March 31, 2001 to $3.7 million for the three months ended
March 31, 2002. Also included in general and administrative expenses is stock compensation expense of $667,000 for the three months ended March 31, 2001 and $596,000 for the three months ended March 31, 2002. The decrease in total general and
administrative expenses between comparable quarters is primarily due to reimbursement of legal expenses of $657,000 received in the first quarter of 2002 resulting from the arbitration proceeding against Enchira Biotechnology Corporation.





General and administrative expenses represented 61% of total revenues for the three months ended March 31, 2001 and 39% for the three months ended March
31, 2002. The decrease was due primarily to the growth in our total revenue between periods.





We expect that our general and administrative expenses will increase in absolute dollar amounts for at least the next several years as we expand our staff and add infrastructure and as a result of increased
professional fees and insurance premiums. We expect that general and administrative expenses as a percentage of total revenue will continue to decrease as our revenues increase and research and development activities expand more quickly than our
general and administrative expenses.





Goodwill and Other Intangible Assets





In connection with the Maxygen ApS acquisition, we allocated $26.2 million to goodwill and other intangible assets and was initially amortizing this goodwill and other
intangible assets over three years. Amortization expense of $2.2 million and $286,000 in the three months ended March 31, 2001 and 2002, respectively, was recorded on goodwill and other intangible assets. See Note 3 of the Notes to Condensed
Consolidated Financial Statements.





Net Interest Income





Net interest income represents income earned on our cash, cash equivalents and marketable securities net of interest expense. Net interest income decreased from $4.0 million for the three months ended March 31, 2001
to $2.2 million for the three months ended March 31, 2002. This decrease was due to lower interest rates and lower average balances of cash, cash equivalents and marketable securities.





Liquidity and Capital Resources





Since inception, we have financed our operations primarily through private
placements and public offerings of equity securities, receiving aggregate consideration from such sales of such equity securities totaling $302.5 million and research and development funding from collaborators and government grants totaling
approximately $140.2 million. As of March 31, 2002, we had $227.0 million in cash, cash equivalents and investments.





Our operating activities used cash
of $3.0 million for the three months ended March 31, 2001 and $6.3 million for the three months ended March 31, 2002. Uses of cash in operating activities were primarily to fund net operating losses.





Net cash provided from investing activities was $11.5 million for the three months ended March 31, 2001 and $32.9 million for the three months ended March 31, 2002. The cash
provided during the three months ended March 31, 2001 and 2002 primarily represented the maturities of available-for-sale securities. This was partially offset by purchases of available-for-sale securities.





Additions of property and equipment were $1.2 million for the three months ended March 31, 2001 and $1.0 million for the three months ended March 31, 2002. We expect to continue
to make significant investments in the purchase of property and equipment to support our expanding operations. We may use a portion of our cash to acquire or invest in complementary businesses, products or technologies, or to obtain the right to use
such complementary technologies.

Financing activities provided cash of $545,000 for the three months ended March 31, 2001 and $500,000 for
the three months ended March 31, 2002. The cash provided in the three months ended March 31, 2001 and 2002 was primarily from the proceeds of the sale of common stock in connection with our Employee Stock Purchase Plan and the exercise of stock
options by employees. This was partially offset by payments on equipment financing obligations.





Assuming our research efforts for existing
collaborations are expended for the full research term, as of March 31, 2002 we have total committed funding of $140.2 million, of which approximately $107.3 million is from our collaborators and $32.9 million is from government funding. Of these
committed funds, we have $51.1 million remaining to be received over the next four years. In addition, potential milestone payments from our existing collaborations could exceed $309 million based on the accomplishment of specific performance
criteria, and we may earn royalties on product sales. In general, the obligation of our corporate collaborators to provide research funding cannot be terminated by either party before the end of the research term unless there has been a material
breach of contract or either party has become bankrupt or insolvent. In the case of such an event, the agreement specifies the rights, if any, that each party will retain.





We believe that our current cash, cash equivalents, short-term investments and long-term investments together with funding received from collaborators and government grants will be sufficient to satisfy our
anticipated cash needs for working capital and capital expenditures for at least the next 12 months. However, it is possible that we will seek additional financing within this timeframe. We may raise additional funds through public or private
financing, collaborative relationships or other arrangements. Additional funding, if sought, may not be available on terms favorable to us. Further, any additional equity financing may be dilutive to stockholders, and debt financing, if available,
may involve restrictive covenants. Our failure to raise capital when needed may harm our business and operating results.





RISK FACTORS
THAT MAY AFFECT RESULTS OF OPERATIONS AND FINANCIAL CONDITION





You should carefully consider the risks described below, together with all of the
other information included in this report, in considering our business and prospects. The risks and uncertainties described below are not the only ones facing Maxygen. Additional risks and uncertainties not presently known to us or that we currently
deem immaterial also may impair our business operations. If any of the following risks actually occur, our business could be harmed. In such case, the trading price of our common stock could decline, and you may lose all or part of your investment.





We Have a History of Net Losses. We Expect to Continue to Incur Net Losses and We May Not Achieve or Maintain Profitability.





We have incurred net losses since our inception, including a net loss of approximately $59.6 million in 2000, $45.0 million in 2001 and $9.0 million in the three
months ended March 31, 2002. As of March 31, 2002, we had an accumulated deficit of approximately $137.7 million. We expect to have increasing net losses and negative cash flow for at least the next several years. The size of these net losses will
depend, in part, on the rate of growth, if any, in our contract revenues and on the level of our expenses. To date, we have derived all our revenues from collaborations and grants and expect to derive a majority of our revenue from such sources for
at least the next several years. Revenues from collaborations and grants are uncertain because our existing agreements have fixed terms and because our ability to secure future agreements will depend upon our ability to address the needs of our
potential future collaborators. We expect to spend significant amounts to fund research and development and enhance our core technologies. As a result of our acquisition of Maxygen ApS, we expect costs to increase further due to expanded operations
and costs associated with operating in multiple international locations. As a result, we expect that our operating expenses will increase significantly in the near term and, consequently, we will need to




18

##### Table of Contents

generate significant additional revenues to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability
on a quarterly or annual basis.





Commercialization of Our Technologies Depends On Collaborations With Other Companies. If We Are Unable to Find
Collaborators in the Future, We May Not Be Able to Develop Our Technologies or Products.





Since we do not currently possess the resources necessary
to develop and commercialize potential products that may result from our technologies, or the resources to complete any approval processes that may be required for these products, we must enter into collaborative arrangements to develop and
commercialize products. We have entered into collaborative agreements with other companies to fund the development of certain new products for specific purposes. These contracts expire after a fixed period of time. If they are not renewed or if we
do not enter into new collaborative agreements, our revenues will be reduced and our products may not be commercialized.





We have limited or no control
over the resources that any collaborator may devote to our products. Any of our present or future collaborators may not perform their obligations as expected. These collaborators may breach or terminate their agreement with us or otherwise fail to
conduct their collaborative activities successfully and in a timely manner. Further, our collaborators may elect not to develop products arising out of our collaborative arrangements or devote sufficient resources to the development, manufacture,
marketing or sale of these products. If any of these events occur, we may not be able to develop our technologies or commercialize our products.





We
Are an Early Stage Company Deploying Unproven Technologies. If We Do Not Develop Commercially Successful Products, We May Be Forced to Cease Operations.





You must evaluate us in light of the uncertainties and complexities affecting an early stage biotechnology company. Our proprietary technologies are new and in the early stage of development. We may not develop products that prove to be
safe and efficacious, meet applicable regulatory standards, are capable of being manufactured at reasonable costs, or can be marketed successfully.





We
may not be successful in the commercial development of products. Successful products will require significant development and investment, including testing, to demonstrate their cost-effectiveness before their commercialization. To date, companies
in the biotechnology industry have developed and commercialized only a limited number of products. We have not proven our ability to develop and commercialize products. We must conduct a substantial amount of additional research and development
before any regulatory authority will approve any of our products. Our research and development may not indicate that our products are safe and effective, in which case regulatory authorities may not approve them. Problems frequently encountered in
connection with the development and utilization of new and unproven technologies and the competitive environment in which we operate might limit our ability to develop commercially successful products.





We Intend to Conduct Proprietary Research Programs, and Any Conflicts With Our Collaborators or Any Inability to Commercialize Products Resulting from This Research Could
Harm Our Business.





An important part of our strategy involves conducting proprietary research programs. We may pursue opportunities in fields that
could conflict with those of our collaborators. Moreover, disagreements with our collaborators could develop over rights to our intellectual property. Any conflict with our collaborators could reduce our ability to obtain future collaboration
agreements and negatively impact our relationship with existing collaborators, which could reduce our revenues.





Certain collaborators could also become
competitors in the future. Our collaborators could develop competing products, preclude us from entering into collaborations with their competitors, fail to obtain timely regulatory approvals, terminate their agreements with us prematurely or fail
to devote sufficient resources to the development and commercialization of products. Any of these developments could harm our product development efforts.





We will either commercialize products resulting from our proprietary programs directly or through licensing to other companies. We have no experience in manufacturing and marketing, and we currently do not have the resources or capability
to manufacture products on a commercial scale. In order for us to commercialize these products directly, we would need to develop, or obtain through outsourcing arrangements, the capability to manufacture, market and sell products. We do not have
these capabilities, and we may not be able to develop or otherwise obtain the requisite manufacturing, marketing and sales capabilities. If we are unable to successfully commercialize products resulting from our proprietary research efforts, we will
continue to incur losses.

We May Encounter Difficulties in Managing Our Growth. These Difficulties Could Increase Our Losses.





We have experienced rapid and substantial growth that has placed and, if this growth continues as expected, will continue to place a strain on our human and capital
resources. If we are unable to manage this growth effectively, our losses could increase. The number of our employees increased from 252 at December 31, 2000 to 305 at December 31, 2001 and at March 31, 2002. Our revenues increased from $24.5
million in 2000 to $30.5 million in 2001 and were $9.3 million in the three months ended March 31, 2002. Our ability to manage our operations and growth effectively requires us to continue to expend funds to enhance our operational, financial and
management controls, reporting systems and procedures and to attract and retain sufficient numbers of talented employees. If we are unable to implement improvements to our management information and control systems in an efficient or timely manner,
or if we encounter deficiencies in existing systems and controls, then management may have access to inadequate information to manage our day-to-day operations. Failure to attract and retain sufficient numbers of talented employees will further
strain our human resources and could impede our growth and ability to satisfy our obligations under collaboration agreements. This would reduce our revenue, increase our losses and harm our reputation in the marketplace.





The Operation of International Locations May Increase Operating Expenses and Divert Management Attention.





We are expanding internationally. In August 2000 we acquired Maxygen ApS, a Danish biotechnology company, and are now operating with international business locations. Expansion into an international operational entity
will require additional management attention and resources. We have limited experience in localizing our operations and in conforming our operations to local cultures, standards and policies. We may have to compete with local companies who
understand the local situation better than we do. We may not be successful in expanding into international locations or in generating revenues from foreign operations. Even if we are successful, the costs of operating internationally are expected to
exceed our international revenues for at least the next several years. As we continue to expand internationally, we are subject to risks of doing business internationally, including the following:





| | · |  | regulatory requirements that may limit or prevent the offering of our products in local jurisdictions;
| | - |  | ------------------------------------------------------------------------------------------------------

| | · |  | government limitations on research and/or research involving genetically engineered products or processes;
| | - |  | ----------------------------------------------------------------------------------------------------------

| | · |  | difficulties in staffing and managing foreign operations;
| | - |  | ---------------------------------------------------------

| | · |  | longer payment cycles, different accounting practices and problems in collecting accounts receivable;
| | - |  | -----------------------------------------------------------------------------------------------------

| | · |  | cultural non-acceptance of genetic manipulation and genetic engineering; and
| | - |  | ----------------------------------------------------------------------------

| | · |  | potentially adverse tax consequences.
| | - |  | -------------------------------------




To the extent we
expand our international operations and have additional portions of our international revenues denominated in foreign currencies, we also could become subject to increased difficulties in collecting accounts receivable and risks relating to foreign
currency exchange rate fluctuations.





Acquisitions Could Result in Dilution, Operating Difficulties and Other Harmful Consequences.





If appropriate opportunities present themselves, we intend to acquire businesses and technologies that complement our capabilities. The process of integrating any
acquisition may create unforeseen operating difficulties and expenditures and is itself risky. The areas where we may face difficulties include:





| | · |  | diversion of management time (both ours and that of the acquired company) from focus on operating the businesses to issues of integration during the period of negotiation
through closing and further diversion of such time after closing;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | · |  | decline in employee morale and retention issues resulting from changes in compensation, reporting relationships, future prospects, or the direction of the business;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | · |  | the need to integrate each companys accounting, management information, human resource and other administrative systems to permit effective management and the lack of
control if such integration is delayed or not implemented; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | · |  | the need to implement controls, procedures and policies appropriate for a larger public company in companies that before acquisition had been smaller, private companies.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



20




---

##### Table of Contents

We do not have extensive experience in managing this integration process. Moreover, the anticipated benefits of any or all of these acquisitions may not be
realized.





Future acquisitions could result in potentially dilutive issuances of equity securities, the incurrence of debt, contingent liabilities or
amortization expenses related to goodwill and other intangible assets, any of which could harm our business. Future acquisitions may require us to obtain additional equity or debt financing, which may not be available on favorable terms or at all.
Even if available, this financing may be dilutive.





Since Our Technologies Can Be Applied to Many Different Industries, If We Focus Our Efforts on
Industries That Fail to Produce Viable Product Candidates, We May Fail to Capitalize on More Profitable Areas.





We have limited financial and
managerial resources. Since our technologies may be applicable to numerous, diverse industries, we must prioritize our application of resources to discrete efforts. This requires us to focus on product candidates in selected industries and forego
efforts with regard to other products and industries. Our decisions may not produce viable commercial products and may divert our resources from more profitable market opportunities.





Public Perception of Ethical and Social Issues May Limit the Use of Our Technologies, Which Could Reduce Our Revenues.





Our success will depend in part upon our ability to develop products discovered through our technologies. Governmental authorities could, for social or other purposes, limit the use of genetic processes or prohibit the practice of our
directed molecular evolution technologies or other technologies. Ethical and other concerns about our directed molecular evolution technologies or other technologies, particularly the use of genes from nature for commercial purposes, and products
resulting therefrom, could adversely affect their market acceptance.





If the Public Rejects Genetically Engineered Products, We Will Have Less Demand
for Our Products.





The commercial success of our potential products will depend in part on public acceptance of the use of genetically engineered
products including drugs, plants and plant products. Claims that genetically engineered products are unsafe for consumption or pose a danger to the environment may influence public attitudes. Our genetically engineered products may not gain public
acceptance. Negative public reaction to genetically modified organisms and products could result in greater government regulation of genetic research and resultant products, including stricter labeling laws or regulations, and could cause a decrease
in the demand for our products.





The subject of genetically modified organisms has received negative publicity in Europe and the United States, which has
aroused public debate. The adverse publicity could lead to greater regulation and trade restrictions on genetic research and the resultant agricultural and other products could be subject to greater domestic or international regulation. Such
regulation and restrictions could cause a decrease in the demand for our products.





Many Potential Competitors Who Have Greater Resources and
Experience Than We Do May Develop Products and Technologies That Make Ours Obsolete.





The biotechnology industry is characterized by rapid
technological change, and the area of gene research is a rapidly evolving field. Our future success will depend on our ability to maintain a competitive position with respect to technological advances. Rapid technological development by others may
result in our products and technologies becoming obsolete.





We face, and will continue to face, intense competition from organizations such as large and
small biotechnology companies, as well as academic and research institutions and government agencies that are pursuing competing technologies for modifying DNA and proteins. These organizations may develop technologies that are alternatives to our
technologies. Further, our competitors in the directed molecular evolution field may be more effective at implementing their technologies to develop commercial products. Some of these competitors have entered into collaborations with leading
companies within our target markets to produce commercial products.





Any products that we develop through our technologies will compete in multiple,
highly competitive markets. Most of the organizations competing with us in the markets for such products have greater capital resources, research and




21

##### Table of Contents

development and marketing staffs and facilities and capabilities, and greater experience in modifying DNA and proteins, obtaining regulatory approvals,
manufacturing products and marketing.





Accordingly, our competitors may be able to develop technologies and products more easily, which would render our
technologies and products and those of our collaborators obsolete and noncompetitive.





Any Inability to Adequately Protect Our Proprietary
Technologies Could Harm Our Competitive Position.





Our success will depend in part on our ability to obtain patents and maintain adequate protection
of our intellectual property for our technologies and products in the U.S. and other countries. If we do not adequately protect our intellectual property, competitors may be able to practice our technologies and erode our competitive advantage. The
laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the U.S., and many companies have encountered significant problems in protecting their proprietary rights in these foreign countries. These problems
can be caused by, for example, a lack of rules and processes allowing for meaningfully defending intellectual property rights.





The patent positions of
biopharmaceutical and biotechnology companies, including our patent positions, are often uncertain and involve complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the
extent that our proprietary technologies are covered by valid and enforceable patents or are effectively maintained as trade secrets. We apply for patents covering our technologies and products as we deem appropriate. However, we may not obtain
patents on all inventions for which we seek patents, and any patents we obtain may be challenged and may be narrowed in scope or extinguished as a result of such challenges. Our existing patents and any future patents we obtain may not be
sufficiently broad to prevent others from practicing our technologies or from developing competing products. Others may independently develop similar or alternative technologies or design around our patented technologies or products. In addition,
others may challenge or invalidate our patents, or our patents may fail to provide us with any competitive advantages.





We rely upon trade secret
protection for our confidential and proprietary information. We have taken security measures to protect our proprietary information. These measures may not provide adequate protection for our trade secrets or other proprietary information. We seek
to protect our proprietary information by entering into confidentiality agreements with employees, collaborators and consultants. Nevertheless, employees, collaborators or consultants may still disclose or misuse our proprietary information, and we
may not be able to meaningfully protect our trade secrets. In addition, others may independently develop substantially equivalent proprietary information or techniques or otherwise gain access to our trade secrets.





Litigation or Other Proceedings or Third Party Claims of Intellectual Property Infringement Could Require Us to Spend Time and Money and Could Shut Down Some of Our
Operations.





Our commercial success depends in part on neither infringing patents nor proprietary rights of third parties, nor breaching any licenses
that we have entered into with regard to our technologies and products. Others have filed, and in the future are likely to file, patent applications covering genes or gene fragments that we may wish to utilize with our proprietary technologies, or
products that are similar to products developed with the use of our technologies or alternative methods of generating gene diversity. If these patent applications result in issued patents and we wish to use the claimed technology, we would need to
obtain a license from the third party.





Third parties may assert that we are employing their proprietary technology without authorization. In addition,
third parties may obtain patents in the future and claim that use of our technologies infringes these patents. We could incur substantial costs and diversion of the time and attention of management and technical personnel in defending ourselves
against any of these claims or enforcing our patents or other intellectual property rights against others. Furthermore, parties making claims against us may be able to obtain injunctive or other equitable relief that could effectively block our
ability to further develop, commercialize and sell products, and such claims could result in the award of substantial damages against us. In the event of a successful claim of infringement against us, we may be required to pay damages and obtain one
or more licenses from third parties. We may not be able to obtain these licenses at a reasonable cost, if at all. In that event, we could encounter delays in product introductions while we attempt to develop alternative methods or products or be
required to cease commercializing affected products.





We routinely monitor the public disclosures of other companies operating in our industry regarding
their technological development efforts. If we determine that these efforts violate our intellectual property or other rights, we intend to take appropriate action, which could include litigation. Any action we take could result in substantial




22




---

##### Table of Contents

costs and diversion of management and technical personnel. Furthermore, the outcome of any action we take to protect our rights may not be resolved in our
favor.





If We Lose Key Personnel or Are Unable to Attract and Retain Additional Personnel We May Be Unable to Pursue
Collaborations or Develop Our Own Products.





We are highly dependent on the principal members of our management and scientific staff, the loss of
whose services might adversely impact the achievement of our objectives. In addition, recruiting and retaining qualified scientific personnel to perform future research and development work will be critical to our success. We do not currently have
sufficient executive management personnel to execute fully our business plan. There is currently a shortage of skilled executives, which is likely to continue. As a result, competition for skilled personnel is intense, and the turnover rate can be
high. Although we believe we will be successful in attracting and retaining qualified personnel, competition for experienced scientists from numerous companies and academic and other research institutions may limit our ability to do so on acceptable
terms. Failure to attract and retain personnel could prevent us from pursuing collaborations or developing our products or core technologies.





Our
planned activities will require additional expertise in specific industries and areas applicable to the products developed through our technologies. These activities will require the addition of new personnel, including management, and the
development of additional expertise by existing management personnel. The inability to acquire these services or to develop this expertise could impair the growth, if any, of our business.





We Will Need Additional Capital in the Future. If Additional Capital is Not Available, We Will Have to Curtail or Cease Operations.





Our future capital requirements will be substantial and will depend on many factors including payments received under collaborative agreements and government grants, the progress and scope of our collaborative and
independent research and development projects, the effect of any acquisitions, and the filing, prosecution and enforcement of patent claims.





Changes may
also occur that would consume available capital resources significantly sooner than we expect. We may be unable to raise sufficient additional capital. If we fail to raise sufficient funds, we will have to curtail or cease operations. We anticipate
that existing cash and cash equivalents and income earned thereon, together with anticipated cash flows from operations, will enable us to maintain our currently planned operations for at least the next 12 months. If our capital resources are
insufficient to meet future capital requirements, we will have to raise additional funds to continue the development of our technologies and complete the commercialization of products, if any, resulting from our technologies.





Some of Our Programs Depend on Government Grants, Which May Be Withdrawn. The Government Has License Rights to Technology Developed With Its Funds.





We have received and expect to continue to receive funds under various U.S. government research and technology development programs. The government
may reduce funding in the future for a number of reasons. For example, some programs are subject to a yearly appropriations process in Congress. Additionally, we may not receive funds under existing or future grants because of budgeting constraints
of the agency administering the program. There can be no assurance that we will receive the entire funding under our existing or future grants.





Our
grants provide the U.S. government a non-exclusive, non-transferable, paid-up license to practice for or on behalf of the inventions made with federal funds. If the government exercises these rights, the U.S. government could use these inventions
and our potential market could be reduced.





Our Potential Therapeutic Products Are Subject to a Lengthy and Uncertain Regulatory Process. If Our
Potential Products Are Not Approved, We Will Not Be Able to Commercialize Those Products.





The Food and Drug Administration must approve any vaccine
or therapeutic product before it can be marketed in the U.S. Before we can file a new drug application or biologic license application with the FDA, the product candidate must undergo extensive testing, including animal and human clinical trials,
which can take many years and require substantial expenditures. Data obtained from such testing are susceptible to varying interpretations that could delay, limit or prevent regulatory approval. In addition, changes in regulatory policy for product
approval during the period of product development and regulatory agency review of each submitted new application or




23




---

##### Table of Contents

product license application may cause delays or rejections. The regulatory process is expensive and time consuming. The regulatory agencies of foreign
governments must also approve our therapeutic products before the products can be sold in those other countries.





Because our products involve the
application of new technologies and may be based upon new therapeutic approaches they may be subject to substantial review by government regulatory authorities and government regulatory authorities may grant regulatory approvals more slowly for our
products than for products using more conventional technologies. We have not submitted an application to the FDA or any other regulatory authority for any product candidate, and neither the FDA nor any other regulatory authority has approved any
therapeutic product candidate developed with our MolecularBreeding directed molecular evolution technologies for commercialization in the U.S. or elsewhere. We may not be able to, or our collaborators may not be able to, conduct clinical testing or
obtain the necessary approvals from the FDA or other regulatory authorities for our products.





Even after investing significant time and expenditures we
may not obtain regulatory approval for our products. Even if we receive regulatory approval, this approval may entail limitations on the indicated uses for which we can market a product. Further, once regulatory approval is obtained, a marketed
product and its manufacturer are subject to continual review, and discovery of previously unknown problems with a product or manufacturer may result in restrictions on the product, manufacturer or manufacturing facility, including withdrawal of the
product from the market. In certain countries, regulatory agencies also set or approve prices.





Laws May Limit Our Provision of Genetically Engineered
Agricultural Products in the Future. These Laws Could Reduce Our Ability to Sell These Products.





We may develop genetically engineered agricultural
products. The field-testing, production and marketing of genetically engineered plants and plant products are subject to federal, state, local and foreign governmental regulation. Regulatory agencies administering existing or future regulations or
legislation may not allow us to produce and market our genetically engineered products in a timely manner or under technically or commercially feasible conditions. In addition, regulatory action or private litigation could result in expenses, delays
or other impediments to our product development programs or the commercialization of resulting products.





The FDA currently applies the same regulatory
standards to foods developed through genetic engineering as apply to foods developed through traditional plant breeding. However, genetically engineered food products will be subject to pre-market review if these products raise safety questions or
are deemed to be food additives. Our products may be subject to lengthy FDA reviews and unfavorable FDA determinations if they raise questions, are deemed to be food additives, or if the FDA changes its policy.





The FDA has also announced in a policy statement that it will not require that genetically engineered agricultural products be labeled as such, provided that these products are
as safe and have the same nutritional characteristics as conventionally developed products. The FDA may reconsider or change its labeling policies, or local or state authorities may enact labeling requirements. Any such labeling requirements could
reduce the demand for our products.





The U.S. Department of Agriculture prohibits genetically engineered plants from being grown and transported except
pursuant to an exemption, or under strict controls. If our future products are not exempted by the USDA, it may be impossible to sell such products.





Adverse Events in the Field of Gene Therapy May Negatively Impact Regulatory Approval or Public Perception of Any Gene Therapy Products We or Our Collaborators May Develop.





Currently, we are not engaged in developing gene therapy products; however, we may engage in these activities in the future either for our own account or with collaborators. If we develop, or our
collaborators develop, gene therapy products, these products may encounter substantial delays in development and approval due to the government regulation and approval process. Adverse events reported in gene therapy clinical trials may lead to more
government scrutiny of proposed clinical trials of gene therapy products, stricter labeling requirements for these products and delays in the approval of gene therapy products for commercial sale.





The commercial success of any potential gene therapy products made by us or our collaborators will depend in part on public acceptance of the use of gene therapies for the
prevention or treatment of human diseases. Public attitudes may be influenced by claims that gene therapies are unsafe, and gene therapy products may not gain the




24




---

##### Table of Contents

acceptance of the public or the medical community. Negative public reaction to gene therapy could result in a decrease in demand for any gene therapy products
we or our collaborators may develop.





Health Care Reform and Restrictions on Reimbursements May Limit Our Returns on Pharmaceutical Products.





Our future products are expected to include pharmaceutical products. Our ability and that of our collaborators to commercialize pharmaceutical
products developed with our technologies may depend in part on the extent to which reimbursement for the cost of these products will be available from government health administration authorities, private health insurers and other organizations.
Third-party payors are increasingly challenging the price of medical products and services. Significant uncertainty exists as to the reimbursement status of newly approved health care products, and there can be no assurance that adequate third party
coverage will be available for any product to enable us to maintain price levels sufficient to realize an appropriate return on our investment in research and product development.





Destructive Actions By Activists or Terrorists Could Damage Our Facilities, Interfere with Our Research Activities and Cause Ecological Harm. Any Such Adverse Events Could Damage Our Ability to Develop Products and
Generate Adequate Revenue to Continue Operations.





Activists and terrorists have recently shown a willingness to damage physical facilities,
equipment and biological materials to publicize and/or further their ideological causes. Recent events in New York City and Washington, D.C. show that the amount of damage people are willing and able to cause can be considerable. Our operations and
research activities could be adversely impacted depending upon the nature and extent of such acts. Such damage could include disability or death of our personnel, damage to our physical facilities, destruction of animals and biological materials,
disruption of our communications and/or data management software used for research and/or destruction of research records. Any such damage could delay our research projects and decrease our ability to conduct future research and development. Damage
caused by activist and/or terrorist incidents could also cause the release of hazardous materials, including chemicals, radioactive and biological materials, which could damage our reputation in the community. Clean up of any such releases could
also be time consuming and costly.





Any significant interruptions in our ability to conduct our business operations or research and development
activities could reduce our revenue and increase our expenses.





We Use Hazardous Chemicals and Radioactive and Biological Materials in Our Business.
Any Claims Relating to Improper Handling, Storage or Disposal of These Materials Could Be Time Consuming and Costly.





Our research and development
processes involve the controlled use of hazardous materials, including chemicals, radioactive and biological materials. Some of these materials may be novel, including viruses with novel properties and animal models for the study of viruses. Our
operations also produce hazardous waste products. Some of our work also involves the development of novel viruses and viral animal models. We cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these
materials. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of these materials. We believe that our current operations comply in all material respects with these laws and regulations. We could
be subject to civil damages in the event of an improper or unauthorized release of, or exposure of individuals to, hazardous materials. In addition, claimants may sue us for injury or contamination that results from our use or the use by third
parties of these materials, and our liability may exceed our total assets. Compliance with environmental laws and regulations may be expensive, and current or future environmental regulations may impair our research, development, or production
efforts. We believe that our current operations comply in all material respects with applicable Environmental Protection Agency regulations.





In
addition, certain of our collaborators are working with these types of hazardous materials in connection with our collaborations. To our knowledge, the work is performed in accordance with biosafety regulations. In the event of a lawsuit or
investigation, we could be held responsible for any injury caused to persons or property by exposure to, or release of, these viruses and hazardous materials. Further, under certain circumstances, we have agreed to indemnify our collaborators
against damages and other liabilities arising out of development activities or products produced in connection with these collaborations.

Our Collaborations With Outside Scientists May Be Subject to Change, Which Could Limit Our Access to Their Expertise.





We work with scientific advisors, consultants and collaborators at academic and other institutions. These scientists are not our employees and may
have other commitments that could limit their availability to us. Although our scientific advisors generally agree not to do competing work, if a conflict of interest between their work for us and their work for another entity arises, we may lose
their services. Although our scientific advisors and collaborators sign agreements not to disclose our confidential information, it is possible that certain of our valuable proprietary knowledge may become publicly known through them.





We May Be Sued for Product Liability.





We may be held liable if
any product we develop, or any product that is made with the use or incorporation of any of our technologies, causes injury or is found otherwise unsuitable during product testing, manufacturing, marketing or sale. These risks are inherent in the
development of chemical, agricultural and pharmaceutical products. Although we intend in the future to obtain product liability insurance, we do not have such insurance currently. Any such insurance that we seek to obtain may be prohibitively
expensive or may not fully cover our potential liabilities. Inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of
products developed by us or our collaborators. If we are sued for any injury caused by our products, our liability could exceed our total assets.





Our
Stock Price Has Been, and May Continue to Be, Extremely Volatile.





The trading prices of life science company stocks in general, and ours in
particular, have experienced extreme price fluctuations in the last two years. The valuations of many life science companies without consistent product revenues and earnings, including ours, are high based on conventional valuation standards such as
price to earnings and price to sales ratios. These trading prices and valuations may not be sustained. Any negative change in the publics perception of the prospects of biotechnology or life science companies could depress our stock price
regardless of our results of operations. Other broad market and industry factors may decrease the trading price of our common stock, regardless of our performance. Market fluctuations, as well as general political and economic conditions such as
recession or interest rate or currency rate fluctuations, also may decrease the trading price of our common stock. In addition, our stock price could be subject to wide fluctuations in response to factors including the following:





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

| | · |  | changes in financial estimates by securities analysts;
| | - |  | ------------------------------------------------------

| | · |  | conditions or trends in the biotechnology and life science industries;
| | - |  | ----------------------------------------------------------------------

| | · |  | changes in the market valuations of other biotechnology or life science companies;
| | - |  | ----------------------------------------------------------------------------------

| | · |  | developments in domestic and international governmental policy or regulations;
| | - |  | ------------------------------------------------------------------------------

| | · |  | announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

| | · |  | developments in or challenges relating to patent or other proprietary rights;
| | - |  | -----------------------------------------------------------------------------

| | · |  | period-to-period fluctuations in our operating results;
| | - |  | -------------------------------------------------------

| | · |  | future royalties from product sales, if any, by our strategic partners; and
| | - |  | ---------------------------------------------------------------------------

| | · |  | sales of our common stock or other securities in the open market.
| | - |  | -----------------------------------------------------------------




In the past, stockholders have often instituted securities class action litigation after periods of volatility in the market price of a companys securities. If a stockholder files a securities class action suit against us, we would
incur substantial legal fees and our managements attention and resources would be diverted from operating our business to respond to the litigation.





In December 2001 a lawsuit was filed in the U.S. District Court for the Southern District of New York against Maxygen, our chief executive officer, Russell Howard, and our then chief financial officer (now president), Simba Gill, together
with certain underwriters of our initial public offering and secondary public offering of common stock. The lawsuit, which alleges claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and Section 10(b) of the Securities Exchange
Act of 1934, is among the so-called laddering cases that have been commenced against a number of companies that had public offerings of securities prior to December 2000. The complaint has been consolidated with other laddering claims in
a proceeding styled In re Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS), pending before the Honorable Shira A. Scheindlin. An amended complaint was served on




26

##### Table of Contents

Maxygen and Drs. Howard and Gill in April 2002. We believe the lawsuit against Maxygen and its officers is without merit and intend to defend against it
vigorously.





We Expect that Our Quarterly Results of Operations Will Fluctuate, and This Fluctuation Could Cause Our Stock Price to Decline.





Our quarterly operating results have fluctuated in the past and are likely to do so in the future. These fluctuations could cause our stock price to
fluctuate significantly or decline. Some of the factors that could cause our operating results to fluctuate include:





| | · |  | expiration of research contracts with collaborators or government research grants, which may not be renewed or replaced;
| | - |  | ------------------------------------------------------------------------------------------------------------------------

| | · |  | the success rate of our discovery efforts leading to milestones and royalties;
| | - |  | ------------------------------------------------------------------------------

| | · |  | the timing and willingness of collaborators to commercialize our products, which would result in royalties; and
| | - |  | ---------------------------------------------------------------------------------------------------------------

| | · |  | general and industry specific economic conditions, which may affect our collaborators research and development expenditures.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------




A large portion of our expenses are relatively fixed, including expenses for facilities, equipment and personnel. Accordingly, if revenues decline or do not grow as anticipated
due to expiration of research contracts or government research grants, failure to obtain new contracts or other factors, we may not be able to correspondingly reduce our operating expenses. Failure to achieve anticipated levels of revenues could
therefore significantly harm our operating results for a particular fiscal period.





Due to the possibility of fluctuations in our revenues and expenses,
we believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance. Our operating results in some quarters may not meet the expectations of stock market analysts and investors. In that case,
our stock price would likely decline.





Some of Our Existing Stockholders Can Exert Control Over Us, and May Not Make Decisions that Are in the Best
Interests of All Stockholders.





Our executive officers, directors and principal stockholders together control approximately 35% of our outstanding
common stock, including GlaxoSmithKline plc, which owns approximately 19% of our outstanding common stock. As a result, these stockholders, if they act together, and GlaxoSmithKline plc by itself, are able to exert a significant degree of influence
over our management and affairs and over matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. In addition, this concentration of ownership may delay or prevent a change in
control of Maxygen and might affect the market price of our common stock, even when a change may be in the best interests of all stockholders. In addition, the interests of this concentration of ownership may not always coincide with our interests
or the interests of other stockholders and accordingly, they could cause us to enter into transactions or agreements that we would not otherwise consider.

ITEM 3


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK





We are exposed to financial market risks, including changes in interest rates and foreign currency exchange. To mitigate some of these risks, we utilize currency forward contracts. We do not use derivative financial instruments for
speculative or trading purposes.





Interest Rate Risk





The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, we maintain our portfolio of cash equivalents, short-term
and long-term investments in a variety of securities, including corporate obligations and money market funds. All securities are held in U.S. currency. As of March 31, 2002, approximately 98% of our total portfolio will mature in one year or less,
with the remainder maturing in less than two years.





The following table represents the fair value balance of our cash, cash equivalents, short-term and
long-term investments that are subject to interest rate risk by year of expected maturity and average interest rates as of March 31, 2002 (dollars in thousands):

We did not hold derivative instruments intended to mitigate interest rate risk as of March 31, 2002, and
we have never held such instruments in the past. If market interest rates were to increase by 100 basis points, or 1% from March 31, 2002 levels, the fair value of our portfolio would decline by approximately $2.3 million. The modeling technique
used measures the changes in fair values arising from an immediate hypothetical shift in market interest rates and assumes ending fair values include principal plus accrued interest. In addition, we had outstanding debt related to equipment
financing of $1.2 million as of March 31, 2002, with a range of interest rates of between 11.73% and 12.78%.





Foreign Currency Exchange Risk





A majority of our revenue, expense and capital purchasing activities are transacted in U.S. dollars. However, in 2000 we acquired a wholly-owned
subsidiary in Denmark, Maxygen ApS. The functional currency of Maxygen ApS is the Danish kroner. To protect against reductions in value and the volatility of future cash flows caused by changes in foreign exchange rates, we have established a cash
flow hedging program. Currency forward contracts are utilized in these hedging programs. Our hedging programs reduce, but do not always eliminate, the impact of foreign currency exchange rate movements. Gains and losses on these foreign currency
investments would generally be offset by corresponding losses and gains on the related hedging instruments, resulting in negligible net exposure to Maxygen.





At March 31, 2002 we had a total of $7.5 million committed in foreign currency cash flow forward contracts.

PART IIOTHER INFORMATION





ITEM 1


LEGAL PROCEEDINGS





In early 2002 we were served with the
complaint, and in April 2002 we were served with an amended complaint, in In re Initial Public Offering Securities Litigation, a so-called laddering case commenced against Maxygen, our chief executive officer, Russell Howard, and
our then chief financial officer (now president), Simba Gill, together with certain underwriters of our initial public offering and secondary public offering. The complaint has been consolidated with other laddering claims and is pending before the
Honorable Shira A. Scheindlin in the United States District Court  Southern District of New York. We believe the lawsuit against Maxygen and its officers is without merit and intent to defend against it vigorously.





ITEM 2


CHANGES IN SECURITIES AND USE OF PROCEEDS





Recent
Sales of Unregistered Securities





On March 1, 2002, we issued 9,984 shares of our common stock in connection with the acquisition of a license of
certain technology. Between January 1, 2002 and March 31, 2002, we issued an aggregate of 9,882 shares of our common stock to three consultants in partial payment for consulting services rendered to us. There was no underwriter employed in
connection with any of the transactions. The issuances of securities were deemed to be exempt from registration under the Securities Act of 1933, as amended (the Securities Act) in reliance on Section 4(2) of the Securities Act and
Regulation D promulgated thereunder as transactions by an issuer not involving a public offering. The recipients of the securities represented their intentions to acquire the securities for investment only and not with a view to or for sale in
connection with any distribution thereof and appropriate legends were affixed to the share certificates issued in the transactions. The recipients either received adequate information about us or had access, through employment or other
relationships, to such information. The recipients, either alone or together with their duly appointed purchaser representatives, were knowledgeable, sophisticated and experienced in making investment decisions of this kind and received adequate
information about us.





Application of Initial Public Offering Proceeds





The effective date of our first registration statement, filed on Form S-1 under the Securities Act (No. 333-89413) relating to our initial public offering of common stock, was December 15, 1999. Net proceeds to us
were approximately $101.0 million. From the effective date through March 31, 2002, the proceeds were applied toward:





| | · |  | purchases and installation of equipment and build-out of facilities, $17.0 million;
| | - |  | -----------------------------------------------------------------------------------

| | · |  | repayment of indebtedness, $854,000;
| | - |  | ------------------------------------

| | · |  | working capital, $34.6 million; and
| | - |  | -----------------------------------

| | · |  | temporary investments in certificates of deposits, mutual funds and corporate debt securities, $48.6 million.
| | - |  | -------------------------------------------------------------------------------------------------------------




The use of the proceeds from the offering does not represent a material change in the use of the proceeds described in the registration statement.
