Wade Secretary The Woodlands, Texas March 28, 2005 LEXICON GENETICS INCORPORATED 8800 TECHNOLOGY FOREST PLACE THE WOODLANDS, TEXAS 77381 (281) 863-3000 --------------- PROXY STATEMENT FOR ANNUAL MEETING OF STOCKHOLDERS TO BE HELD APRIL 27, 2005 GENERAL INFORMATION PURPOSE OF THIS PROXY STATEMENT We have prepared this proxy statement to solicit proxies on behalf of our Board of Directors for use at our 2005 annual meeting of stockholders and any adjournment or postponement thereof. We are mailing this proxy statement and the accompanying notice of annual meeting of stockholders and form of proxy to our stockholders on or about March 28, 2005. TIME AND PLACE OF ANNUAL MEETING The annual meeting will be held on Wednesday, April 27, 2005 at 1:30 p.m., local time, at The Marriott Woodlands Waterway Hotel and Convention Center, 1601 Lake Robbins Drive, The Woodlands, Texas. MATTERS TO BE CONSIDERED AT THE ANNUAL MEETING At the annual meeting, our stockholders will be asked to consider and act upon the following matters: - the election of two Class II directors; - a proposal to ratify and approve an amendment to our 2000 Non-Employee Directors' Stock Option Plan increasing the number of shares of common stock underlying each annual option grant from 6,000 shares to 10,000 shares; and - a proposal to ratify and approve the appointment of Ernst & Young LLP as our independent auditors for the fiscal year ending December 31, 2005. Our Board of Directors does not intend to bring any other matters before the annual meeting and has not been informed that any other matters are to be presented by others. Our bylaws contain several requirements that must be satisfied in order for any of our stockholders to bring a proposal before one of our annual meetings, including a requirement of delivering proper advance notice to us. Stockholders are advised to review our bylaws if they intend to present a proposal at any of our annual meetings. RECORD DATE FOR DETERMINING ENTITLEMENT TO VOTE You are entitled to vote at the annual meeting if you were the record owner of shares of our common stock as of the close of business on March 8, 2005, the record date for the annual meeting established by our Board of Directors. HOW TO VOTE YOUR SHARES You may vote in person at the annual meeting or by proxy. To ensure that your shares are represented at the annual meeting, we recommend you vote by proxy even if you plan to attend the annual meeting in person. Even if you 1 vote by proxy, if you wish, you can revoke your proxy and vote in person at the annual meeting. If you want to vote at the annual meeting but your shares are held by an intermediary, such as a broker or bank, you will need to obtain from the intermediary either proof of your ownership of such shares as of March 8, 2005 or a proxy to vote your shares. You may receive more than one proxy depending on how you hold your shares. If you hold your shares through someone else, such as a broker or a bank, you may get materials from them asking you how you want your shares to be voted at the annual meeting. QUORUM We must have a quorum to conduct any business at the annual meeting. This means that at least a majority of our outstanding shares eligible to vote at the annual meeting must be represented at the annual meeting, either in person or by proxy. Abstentions are counted for purposes of determining whether a quorum is present. In addition, shares of our common stock held by intermediaries that are voted for at least one matter at the annual meeting will be counted as being present for purposes of determining a quorum for all matters, even if the beneficial owner's discretion has been withheld for voting on some or all other matters (commonly referred to as a "broker non-vote"). OUTSTANDING SHARES On the record date, we had 63,538,171 shares of our common stock outstanding. If you were the record owner of shares of our common stock on the record date, you will be entitled to one vote for each share of stock that you own on each matter that is called to vote at the annual meeting. VOTE NEEDED TO APPROVE PROPOSALS Our Class II directors will be elected by a plurality vote. As a result, if a quorum is present at the annual meeting, the two persons receiving the greatest number of votes will be elected to serve as our Class II directors. Withholding authority to vote for a director nominee will not affect the outcome of the election of directors. The ratification and approval of the amendment to our 2000 Non-Employee Directors' Stock Option Plan, the appointment of Ernst & Young LLP as our independent auditors for the year ending December 31, 2005 and any other business that may properly come before the annual meeting for a vote, will require a majority of the votes cast with respect to such matter (unless a greater vote is required by law or our charter or bylaws). On any such matter, an abstention from voting will have the same effect as a vote against the proposal. Broker non-votes do not count as votes for or against these proposals and are not considered in calculating the number of votes necessary for approval. HOW YOUR PROXY WILL BE VOTED Giving us your proxy means that you are authorizing us to vote your shares at the annual meeting in the manner you direct. You may vote for our nominees for election as Class II directors or withhold your vote for any one or more of those nominees. You may vote for or against the proposals to ratify and approve the amendment to our 2000 Non-Employee Directors' Stock Option Plan and the appointment of Ernst & Young LLP as our independent auditors for the year ending December 31, 2005, or abstain from voting on those proposals. If you sign and return the enclosed proxy card and do not withhold authority to vote for the election of our nominees for election as Class II directors, all of your shares will be voted for the election of those nominees. If you withhold authority to vote for one or more of our nominees for election as Class II directors, none of your shares will be voted for those nominees. If any of our nominees for election as Class II directors become unavailable for any reason before the election, we may reduce the number of directors serving on our Board of Directors, or our Board of Directors may designate substitute nominees, as necessary. We have no reason to believe that any of our nominees for election as Class II directors will be unavailable. If our Board of Directors designates any substitute nominees, the persons named in the enclosed proxy card will vote your shares for such substitute(s) if they are instructed to do so by our Board of Directors or, in the absence of any such instructions, in accordance with their own best judgment. If you sign and return the enclosed proxy but do not specify how you want your shares voted, your shares will be voted in favor of our nominees for election as Class II directors and in favor of the proposals to ratify and approve the 2 amendment to our 2000 Non-Employee Directors' Stock Option Plan and the appointment of Ernst & Young LLP as our independent auditors for the year ending December 31, 2005. If you sign and return the enclosed proxy and any additional business properly comes before the annual meeting, the persons named in the enclosed proxy will vote your shares on those matters as instructed by our Board of Directors or, in the absence of any such instructions, in accordance with their own best judgment. As of the date of this proxy statement, we are not aware of any other matter to be raised at the annual meeting. HOW TO REVOKE YOUR PROXY You may revoke your proxy at any time before your shares are voted by providing our Corporate Secretary with either a new proxy with a later date or a written notice of your desire to revoke your proxy at the following address: Lexicon Genetics Incorporated 8800 Technology Forest Place The Woodlands, Texas 77381 Attention: Corporate Secretary You may also revoke your proxy at any time prior to your shares having been voted by attending the annual meeting in person and notifying the inspector of election of your desire to revoke your proxy. Your proxy will not automatically be revoked merely because you attend the annual meeting. INSPECTOR OF ELECTION Mellon Investor Services L.L.C., our transfer agent and registrar, will count votes and provide a representative who will serve as an inspector of election for the annual meeting. LIST OF STOCKHOLDERS ENTITLED TO VOTE A list of our stockholders entitled to vote at the annual meeting will be available for inspection at the annual meeting.

Any inspection of this list at our offices will need to be conducted during ordinary business hours. If you wish to conduct an inspection of the stockholder list, we request that you please contact our Corporate Secretary before coming to our offices. SOLICITATION OF PROXIES AND EXPENSES We are asking for your proxy on behalf of our Board of Directors. We will bear the entire cost of preparing, printing and soliciting proxies. We will send proxy solicitation materials to all of our stockholders of record as of the record date and to all intermediaries, such as brokers and banks, that held any of our shares on that date on behalf of others. These intermediaries will then forward solicitation materials to the beneficial owners of our shares, and we will reimburse them for their reasonable out-of-pocket expenses for forwarding such materials. Our directors, officers and employees may solicit proxies by mail, in person or by telephone or other electronic communication. Our directors, officers and employees will not receive additional compensation for their solicitation efforts, but they will be reimbursed for any out-of-pocket expenses they incur. HOUSEHOLDING OF ANNUAL DISCLOSURE DOCUMENTS The Securities and Exchange Commission has approved a rule allowing us to send a single set of our annual report and proxy statement to any household at which two or more stockholders reside if we believe the stockholders are members of the same family. This rule benefits both you and us by reducing the volume of duplicate information received at your household and helping to reduce our expenses. The rule applies to our annual reports, proxy statements and information statements. Each stockholder will continue to receive a separate proxy card or voting instruction card. If your household received a single set of disclosure documents for this year, but you would prefer to receive your own copy, please contact our transfer agent, Mellon Investor Services L.L.C., by calling their toll-free number, (800) 635-9270. If you would like to receive your own set of our annual disclosure documents in future years, follow the instructions described below. Similarly, if you share an address with another stockholder and together both of you would like to receive only a single set of our annual disclosure documents, follow these instructions: 3 - If your shares are registered in your own name, please contact our transfer agent, Mellon Investor Services, and inform them of your request by calling them at (800) 635-9270 or writing them at 85 Challenger Road, Ridgefield Park, New Jersey 07660. - If a broker or other nominee holds your shares, please contact ADP and inform them of your request by calling them at (888) 603-5847 or writing them at Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

INDEPENDENCE OF THE BOARD OF DIRECTORS After reviewing all relevant transactions and relationships between each member of the Board of Directors (and his or her family) and us, our senior management and our independent auditors, the Board of Directors has affirmatively determined that Samuel L.

Rose, which members constitute a majority of the Board of Directors, are "independent" in accordance with the applicable listing standards of The Nasdaq Stock Market, Inc. BOARD COMMITTEES Audit Committee. Our audit committee monitors the integrity of our financial statements, reviews our internal accounting procedures and oversees the qualifications, independence and performance of our independent auditors. The current members of our audit committee are Clayton S. Rose (chair), Samuel L. Barker, Ph.D. and Patricia M. Cloherty. The Board of Directors, in its business judgment, has determined that Mr. Rose, Dr. Barker and Ms. Cloherty are "independent" in accordance with the provisions of the Securities Exchange Act of 1934, including all rules and regulations promulgated thereunder. The Board of Directors has further determined that Mr. Rose, Dr. Barker and Ms. Cloherty are "independent" in accordance with the applicable listing standards of The Nasdaq Stock Market, Inc.

Compensation Committee. Our compensation committee evaluates the performance of management, determines the compensation of our executive officers and reviews general policy relating to compensation and benefits of our employees.

The Board of Directors, in its business judgment, has determined that Ms. Cloherty, Dr. Barker, Mr. Palantoni and Mr. Rose are "independent" in accordance with the applicable listing standards of The Nasdaq Stock Market, Inc. Corporate Governance Committee. Our corporate governance committee identifies individuals qualified to become members of our Board of Directors, selects candidates or nominees for director positions to be filled by the Board of Directors or our stockholders and develops appropriate corporate governance principles. The corporate governance committee operates pursuant to a charter that was approved by the Board of Directors on February 11, 2004, a copy of which appears on our website at www.lexicon-genetics.com under the caption "Investor Relations - Corporate Governance." The corporate governance committee has not established any specific minimum qualifications for membership on our Board of Directors. Rather, the committee will generally consider all relevant factors, which may include independence, experience, diversity, leadership qualities and strength of character. The corporate governance committee uses its available network of contacts when compiling a list of potential director candidates and may also engage outside consultants when appropriate. The committee also considers potential director candidates recommended by stockholders and other parties and all potential director candidates are evaluated based on the above criteria. Because the corporate governance committee makes no distinction in its evaluation of candidates based on whether such candidates are recommended by stockholders or other parties, no formal policy or procedure has been established for the consideration of director candidates recommended by stockholders. 9 Any stockholder wishing to propose a potential director candidate may submit a recommendation in writing within the timeframe specified in our bylaws. All such communications should be sent to 8800 Technology Forest Place, The Woodlands, Texas 77381, Attn: Corporate Governance Committee. Submissions should include the full name of the proposed candidate and a detailed description of the candidate's qualifications, business experience and other relevant biographical information.

Lefkowitz, M.D. The Board of Directors, in its business judgment, has determined that Mr. Palantoni and Dr. Lefkowitz are "independent" in accordance with the applicable listing standards of The Nasdaq Stock Market, Inc. BOARD AND COMMITTEE MEETINGS IN 2004 The Board of Directors met five times in 2004 and took certain additional actions by unanimous written consent. The audit committee and compensation committee each met four times and the corporate governance committee met two times in 2004. During 2004, none of our directors attended fewer than 75 percent of the aggregate number of meetings of the Board of Directors and committees during the period served. DIRECTOR COMPENSATION Each director other than Arthur T. Sands, M.D., Ph.D. currently receives the following cash compensation: - an annual retainer of $15,000 for service on the Board of Directors (prorated for any partial year of service); - an annual retainer of $2,500 for service on each committee of the Board of Directors of which he or she is a member (prorated for any partial year of service) ($5,000 for service as chairman of any such committee); - a fee $2,500 for each meeting of the Board of Directors that he or she attends in person ($500 for each telephonic meeting of the Board of Directors in which he or she participates); and - a fee of $1,000 for each committee meeting that he or she attends in person (other than in connection with a meeting of the full Board of Directors) ($500 for each telephonic committee meeting in which he or she participates). Dr. Sands does not receive additional compensation for his service as a director. Dr. Nies receives payment of $75,000 per year for his service as Chairman of our Medical Advisory Board. Until March 2005, Dr. Caskey received payment of $150,000 per year for his service as non-executive Chairman of our Board of Directors. Dr. Caskey currently receives payment of $75,000 per year for his consulting services. Dr. Lefkowitz receives payment of $50,000 per year for his consulting services. All directors are reimbursed for expenses in connection with attendance at Board of Directors and committee meetings. Our 2000 Non-Employee Directors' Stock Option Plan provides for the grant of options to purchase shares of common stock to our directors who are not employees. Non-employee directors first elected after the closing of our initial public offering receive an initial option to purchase 30,000 shares of common stock. In addition, all non-employee directors who have served in such capacity for six months currently receive an annual option to purchase 6,000 shares of common stock. The proposed amendment to the non-employee directors' plan would increase the number of shares underlying the annual option grants from 6,000 shares to 10,000 shares. All options granted under the non-employee directors' plan have an exercise price equal to the fair market value of our common stock on the date of grant. At the time of our annual meeting of stockholders in May 2004, each of Dr. Caskey, Dr. Barker, Ms. Cloherty, Dr. Lefkowitz and Dr. Nies received options under the 2000 Non-Employee Directors' Stock Option Plan to purchase 6,000 shares of common stock at an exercise price of $6.84 per share, the fair market value of our common stock on the date of grant as determined in accordance with the plan. In July 2004, in connection with his election as a director, Mr. Rose received an initial option under the 2000 Non-Employee Directors' Stock Option Plan to purchase 30,000 shares of common stock at an exercise price of $5.92 per share, the fair market value of our common stock on the date of grant as determined in accordance with the plan. In November 2004, in connection with his election as a director, Mr. Palantoni received an initial option under the 2000 Non-Employee Directors' Stock Option Plan to purchase 30,000 shares of 10 common stock at an exercise price of $6.79 per share, the fair market value of our common stock on the date of grant as determined in accordance with the plan. STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS We believe that our stockholders are currently provided a reasonable means to communicate with our Board of Directors or individual directors. As a result, our Board of Directors has not established a formal process for stockholders to send communications to the Board of Directors or individual directors. However, the corporate governance committee will consider, from time to time, whether adoption of a formal process for such stockholder communications has become necessary or appropriate. Stockholders may send communications to the Board of Directors or individual directors by mail at 8800 Technology Forest Place, The Woodlands, Texas 77381, Attn: Board of Directors. CODE OF BUSINESS CONDUCT AND ETHICS We have adopted a code of business conduct and ethics that applies to all of our directors, officers and employees, the text of which appears on our website at www.lexicon-genetics.com under the caption "Investor Relations - Corporate Governance." We intend to disclose on our website the nature of any amendment to or waiver from our code of business conduct and ethics that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions within five business days following the date of such amendment or waiver. In the case of any such waiver, including an implicit waiver, we also intend to disclose the name of the person to whom the waiver was granted and the date of the waiver. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During 2004, Patricia M. Cloherty and Samuel L. Barker, Ph.D. served as members of the compensation committee of our Board of Directors. No member of the compensation committee serves as a member of the board of directors or compensation committee of any other entity that has one or more executive officers serving as a member of our board of directors or compensation committee. PROPOSAL NUMBER 2: RATIFICATION AND APPROVAL OF AMENDMENT TO 2000 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN We use stock option awards as a part of our overall compensation program in order to align the long-term interests of the non-employee members of our Board of Directors with those of our stockholders. These awards are made under our 2000 Non-Employee Directors' Stock Option Plan, the purpose of which is to secure and retain the services of non-employee directors, and to provide them with incentives to exert maximum efforts for the company's success by giving them the opportunity through the granting of nonstatutory stock options to benefit from increases in the value of our common stock. The plan was adopted by our Board of Directors on February 3, 2000 and approved by our stockholders on March 15, 2000. The plan currently provides that all non-employee directors who have served in such capacity for six months shall be granted an annual option to purchase 6,000 shares of common stock. We are asking that stockholders ratify and approve an amendment to the plan increasing the number of shares underlying the annual option grants to 10,000 shares so that this portion of our overall compensation program remains competitive in comparison to the compensation programs of our peer group companies. The terms of the 2000 Non-Employee Directors' Stock Option Plan are summarized below and the complete text of the plan is set forth in Appendix A to this proxy statement, in each case, reflecting the amendment described above. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" RATIFICATION AND APPROVAL OF THE AMENDMENT TO THE 2000 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN. 11 ADMINISTRATION OF THE PLAN The plan is administered by our Board of Directors, which oversees the grant of options under the plan and determines the provisions of each option granted, to the extent not specified in the plan. AWARDS UNDER THE PLAN The plan only permits the award of nonstatutory stock options. Stock options granted under the plan are evidenced by agreements that specify the terms and conditions under which they are granted. All stock options granted under the plan are subject to the terms and conditions contained in the applicable agreement and the plan. ELIGIBILITY Stock options are granted to non-employee directors under the plan. Upon the date of his or her initial election or appointment to the Board of Directors, each non-employee director is granted an option to purchase 30,000 shares of our common stock. Further, on the day following each annual meeting of stockholders, beginning in 2001, each person who is then a non-employee director and has been a non-employee director for at least six months is granted an option to purchase 10,000 shares of our common stock. Seven of the eight members of our Board of Directors are currently eligible to participate in the plan. SHARES SUBJECT TO THE PLAN We have reserved an aggregate of 600,000 shares of our common stock for issuance under the plan. The plan provides that, on the day following the annual meeting of stockholders of each year for ten years, beginning in 2000, the number of shares reserved for issuance under the plan will be automatically increased by the greater of: - 0.3% of our outstanding shares on a fully-diluted basis; or - that number of shares that could be issued under stock options granted under the Plan during the prior year. However, our Board of Directors may provide for a smaller annual increase in the number of shares reserved for issuance under the plan. In each of the last five years, the Board of Directors has limited the number of shares reserved for issuance under the plan to the 600,000 shares initially reserved under the plan. If any stock option expires, lapses, or is terminated or forfeited for any reason, the shares subject to that stock option will continue to be available for the grant of stock options under the plan. Common stock issued on the exercise of stock options under the plan may be either authorized and unissued shares or reacquired shares. As of March 1, 2005, there were options outstanding under the plan to purchase a total of 198,000 shares of our common stock and 402,000 shares remained available for issuance of new options. To date, no shares have been issued upon the exercise of options granted under the plan. STOCK OPTIONS The stock options granted under the plan are evidenced by agreements that specify the number of shares of our common stock which may be purchased at a certain specified price and contain other terms and conditions, such as vesting and termination provisions. All stock options granted under the plan are subject to the terms and conditions contained in the applicable stock option agreement and the plan. Vesting and Exercisability Stock options granted under the plan "vest," or become exercisable, as follows: - Initial grants of options to purchase 30,000 shares of our common stock provide for vesting of 1/60th of the shares subject to the option each month after grant for five years after the date of grant. - Annual grants of options to purchase 10,000 shares of our common stock provide for vesting of 1/12th of the shares subject to the option each month after grant for twelve months after the date of the grant. 12 Expiration and Termination Stock options granted under the plan have a term of ten years from the date of grant, subject to earlier termination upon the occurrence of certain events. In no event, however, may a stock option be exercised more than ten years after the date the option is granted. Option Exercise Price Stock options awarded under the plan have an exercise price of 100% of the fair market value of our common stock on the date of grant. The fair market value of a share of common stock on a particular date is equal to the previous day's closing sales price (or the closing bid price, if no sales were reported) of the common stock if the common stock is listed on any established stock exchange or traded on the Nasdaq Stock Market. If there is no regular public trading market for the common stock, the fair market value of the common stock is determined by our Board of Directors. Consideration for Exercise of Options The consideration to be paid for shares to be issued upon exercise of a stock option, including the method of payment, may be paid, to the extent permitted by law, in any combination of (1) cash or (2) delivery of other shares of our common stock (which must have been held at least six months). OTHER PROVISIONS Limits on Transfer of Stock Options In general, non-employee directors may not sell, pledge, assign, transfer or otherwise dispose of any stock options other than (i) by will or the laws of descent or distribution, (ii) in certain circumstances, by instrument to an inter vivos or testamentary trust and (iii) by gift to a member of such non-employee director's immediate family. Adjustments on Changes in Capital Structure or on Change of Control If we effect a stock split, reverse stock split, stock dividend, redemption, combination, reclassification or other similar change affecting our capital stock, adjustments reflecting the change will be made in (1) the aggregate number of shares of common stock authorized for issuance under the plan; (2) the number of shares underlying each outstanding stock option; and (3) the exercise price per share subject to each outstanding stock option. If a change in control transaction shall occur, the surviving or acquiring corporation shall assume all stock options or provide or substitute similar stock options. If the surviving or acquiring corporation refuses to so provide such assumption or substitution, then the vesting of stock options granted under the plan will be accelerated in full and the stock options will subsequently terminate if not exercised. If a change in control transaction shall occur and the surviving or acquiring corporation assumes the stock options granted under the plan, but any non-employee director is not elected or appointed to the Board of Directors of the surviving or acquiring corporation, then the vesting of that non-employee director's stock options shall be accelerated by 18 months. Amendment or Termination of the Plan The Board of Directors may at any time amend, alter, suspend or discontinue the plan but no amendment, alteration, suspension or discontinuation which would impair the rights of a non-employee director under any previous grant may be made without such non-employee director's consent. Term of the Plan No stock options may be granted under the plan after February 3, 2010. 13 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES The following is a brief summary of certain of the federal income tax consequences of certain transactions under the plan based on current federal income tax laws. This summary is not intended to be exhaustive and does not describe state or local tax consequences. Additional or different federal tax consequences to the non-employee director or to us may result depending on considerations other than those described below. In general, optionholders will not recognize any taxable income at the time they are granted a nonstatutory stock option. When an optionholder exercises a nonstatutory stock option, he or she will recognize ordinary income measured by the excess of the then fair market value of the shares over the exercise price and we will be entitled to a deduction for a corresponding amount. Different rules apply to options that have a "readily ascertainable fair market value," as that phrase is defined in regulations promulgated under Section 83 of the Internal Revenue Code of 1986. When an optionholder sells or otherwise disposes of shares that were acquired by exercising a nonstatutory stock option, any amount the optionholder receives in excess of the sum of (1) the exercise price of the shares as of the date of exercise and (2) the amount includable in income with respect to such option, if any, such sum being the optionholder's "basis" in the shares, will, in general, be treated as a long term or short term capital gain, depending on the holding period of the shares. We are not entitled to any tax deduction in connection with an optionholder's sale or disposition of the shares. If an optionholder receives less than his or her basis in the shares, the loss will, in general, be treated as a long term or short term capital loss, depending on the holding period of the shares. The foregoing summary does not constitute a definitive statement of the federal income tax effects of stock options granted under the plan. PROPOSAL NUMBER 3: RATIFICATION AND APPROVAL OF INDEPENDENT AUDITORS The Board of Directors has appointed the firm of Ernst & Young LLP as our independent auditors to make an examination of our accounts for the fiscal year ending December 31, 2005, subject to ratification by our stockholders. Representatives of Ernst & Young LLP, are expected to be present at the annual meeting, will have an opportunity to make a statement if they desire to do so and are expected to be available to respond to appropriate questions. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" RATIFICATION AND APPROVAL OF THE APPOINTMENT OF ERNST & YOUNG LLP AS OUR INDEPENDENT AUDITORS FOR THE FISCAL YEAR ENDING DECEMBER 31, 2005. COMPENSATION OF INDEPENDENT AUDITORS The following table presents the estimated aggregate fees billed and to be billed by Ernst & Young LLP for services performed during our last two fiscal years.

As part of its duties, the audit committee has determined that the provision by Ernst & Young LLP of the non-audit services described above is compatible with maintaining the auditors' independence. Pre-Approval Policies and Procedures The audit committee has adopted policies and procedures requiring the pre-approval of all audit and non-audit services rendered by our independent auditors, either as part of the audit committee's approval of the scope of the engagement of the independent auditors or on a case-by-case basis before the independent auditors are engaged to provide each service. The audit committee's pre-approval authority may be delegated to one or more of its members, but any pre-approval decision must be reported to the full audit committee at its next regularly scheduled meeting.

REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS The compensation committee of our Board of Directors currently consists of Patricia M. Cloherty, Samuel L. Barker, Ph.D., Frank Palantoni and Clayton S. Rose, none of whom is an officer or employee of the company. The compensation committee is responsible for evaluating the performance of management, determining the compensation of our executive officers and administering our 2000 Equity Incentive Plan, under which stock option grants and other stock awards may be made to our employees. The committee has furnished the following report on executive compensation for 2004: Executive Compensation Policies and Practices Under the supervision of the compensation committee, our company has developed a compensation policy that is designed to attract and retain key executives responsible for our success and motivate management to enhance long-term stockholder value. The annual compensation package for executive officers primarily consists of: - a cash salary, which reflects the responsibilities relating to the position and individual performance; - variable performance awards payable in cash or stock and tied to the achievement of specified individual and corporate goals and milestones; and - long-term stock based incentive awards which strengthen the mutuality of interests between our executive officers and our stockholders. In determining the level and composition of compensation of each of our executive officers, the compensation committee takes into account various qualitative and quantitative indicators of corporate and individual performance. Although no specific target has been established, the committee generally seeks to set total compensation, including base salaries and variable performance award targets, at or above the median of the range in comparison to peer group companies. In setting such total compensation, the committee considers our peer group to be similarly sized companies in the biotechnology industry. This peer group does not necessarily coincide with the companies comprising the Nasdaq Biotechnology Index reflected in the performance graph in this proxy statement. Because our business and technology are continuing to develop, the use of certain traditional performance standards, such as profitability and return on equity, are not currently appropriate in evaluating the performance of our executive officers. Consequently, in evaluating the performance of management, the committee takes into consideration such factors as our achievement of specified milestones and goals with respect to our revenues, new business development, and our research and development programs. In addition, the committee recognizes performance and achievements that are more difficult to quantify, such as the successful supervision of major corporate projects and demonstrated leadership ability. 20 Base Compensation Base compensation is established through negotiation between the company and the executive officer at the time the executive is hired, and then subsequently adjusted when the officer's base compensation is subject to review or reconsideration. While we have entered into employment agreements with certain of our executive officers, these agreements provide that base salaries after the initial year will be reviewed and determined by the committee. When establishing or reviewing base compensation levels for executive officers, the committee, in accordance with its general compensation policy, considers numerous factors, including the responsibilities relating to the position, the qualifications of the executive and the relevant experience the individual brings to the company, strategic goals for which the executive has responsibility, and compensation levels of companies at a comparable stage of development who compete with us for business, scientific and executive talents. No pre-determined weights are given to any one of these factors. The base salaries for the executive officers generally, and the Chief Executive Officer specifically, for 2004 were competitive with those paid by our peer group companies, with most falling in a range around the 50th to 75th percentile for such peer group companies. In establishing base compensation for 2004, the committee included in its evaluation the significant progress made by the company in 2003, including the significant increase in our revenues as compared to 2002, the establishment of a major new drug discovery alliance with Bristol-Myers Squibb Company, the completion of a significant public offering of our common stock and the continuing advancement of our research and development programs. Incentive Compensation In addition to base compensation, the committee may award cash bonuses and option grants or other stock-based awards under our 2000 Equity Incentive Plan to chosen executive officers depending on the extent to which certain defined personal and corporate performance goals are achieved. These performance goals include those discussed generally above, as well as strategic and operational goals for the company as a whole. In determining bonus and stock option awards for 2004, the committee included in its evaluation the progress made by the company in 2004, including the advancement of two drug discovery programs into preclinical development, the significant increase in our revenues as compared to 2003, the establishment of our drug discovery alliance with Takeda Pharmaceutical Company Limited, our execution and performance under our existing drug discovery alliances with Bristol Myers Squibb Company and Genentech, Inc. and the continuing advancement of our other research and development programs. All of our employees, including our executive officers, are eligible to receive long-term stock-based incentive awards under our 2000 Equity Incentive Plan as a means of providing such individuals with a continuing proprietary interest in our success. These grants align the interests of our employees and our stockholders by providing significant incentives for our employees to achieve and maintain high levels of performance. Our 2000 Equity Incentive Plan enhances our ability to attract and retain the services of qualified individuals. Factors considered in determining whether such awards are granted to an executive officer include the executive's position, his or her performance and responsibilities, the amount of stock options currently held by the officer, the vesting schedules of any such options and the executive officer's other compensation. While the committee does not adhere to any firmly established formulas or schedules for the issuance of awards such as options or restricted stock, the committee will generally tailor the terms of any such grant to achieve its goal as a long-term incentive award by providing for a vesting schedule encompassing several years. In February 2004, the committee approved annual stock option grants to executive officers and other employees who satisfied eligibility requirements, including time of service. In making such grants, the committee considered corporate and individual performance over the year preceding the grant date and information regarding stock option grants made by other companies in the biotechnology industry. Compensation of the Chief Executive Officer The annual base salary of Arthur T. Sands, M.D., Ph.D., our President and Chief Executive Officer, was $432,000 for 2003, unchanged from 2002. In February 2004, the committee increased Dr. Sands' base salary by $41,000 (or approximately nine percent) to $473,000 and awarded a bonus to Dr. Sands for 2003 in the amount of $249,830, in each case on the basis of his and the company's achievements in 2003 relative to performance goals established at the outset of the year. In February 2005, the committee awarded a bonus to Dr. Sands for 2004 in the amount of $205,244 on 21 the basis of his and the company's achievements in 2004 relative to performance goals established at the outset of the year. At the same time, the committee elected to leave Dr. Sands' annual base salary for 2005 unchanged from 2004. The committee granted a stock option to Dr. Sands in February 2004, at the same time annual grants were made to other employees. The stock option entitles Dr. Sands to purchase an aggregate of 150,000 shares of common stock at an exercise price of $7.59 per share. In making the option grant to Dr. Sands, the committee considered the factors described above with respect to the February 2004 option grants generally. Section 162(m) Section 162(m) of the Internal Revenue Code places a $1 million cap per executive on the deductible compensation that can be paid to certain executives of publicly-traded corporations. Amounts that qualify as "performance based" compensation under Section 162(m)(4)(c) of the Code are exempt from the cap and do not count toward the $1 million limit. Generally, stock options will qualify as performance based compensation. The committee has discussed and considered and will continue to evaluate the potential impact of Section 162(m) on the company in making compensation determinations, but has not established a set policy with respect to future compensation determinations.

(d) SOURCE OF SHARES. The shares of Common Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. A-3 APPENDIX A 5. ELIGIBILITY. The Options as set forth in section 6 automatically shall be granted under the Plan to all Non-Employee Directors. 6. NON-DISCRETIONARY GRANTS. (a) INITIAL GRANTS. Without any further action of the Board, each person who is elected or appointed for the first time to be a Non-Employee Director automatically shall, upon the date of his or her initial election or appointment to be a Non-Employee Director, be granted an Initial Grant to purchase Thirty Thousand (30,000) shares of Common Stock on the terms and conditions set forth herein. (b) ANNUAL GRANTS. Without any further action of the Board, on the day following each Annual Meeting, commencing with the Annual Meeting in 2001, each person who is then a Non-Employee Director, and has been a Non-Employee Director for at least six (6) months, automatically shall be granted an Annual Grant to purchase Ten Thousand (10,000) shares of Common Stock on the terms and conditions set forth herein. 7. OPTION PROVISIONS. Each Option shall be in such form and shall contain such terms and conditions as required by the Plan. Each Option shall contain such additional terms and conditions, not inconsistent with the Plan, as the Board shall deem appropriate. Each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: (a) TERM. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted. (b) EXERCISE PRICE. The exercise price of each Option shall be one hundred percent (100%) of the Fair Market Value of the stock subject to the Option on the date the Option is granted. (c) CONSIDERATION. The purchase price of stock acquired pursuant to an Option may be paid, to the extent permitted by applicable statutes and regulations, in any combination of (i) cash or check, or (ii) delivery to the Company of other Common Stock. The purchase price of Common Stock acquired pursuant to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). At any time that the Company is incorporated in Delaware, payment of the Common Stock's "par value," as defined in the Delaware General Corporation Law, shall not be made by deferred payment. (d) TRANSFERABILITY. An Option is not transferable, except (i) by will or by the laws of descent and distribution, (ii) by instrument to an inter vivos or testamentary trust, in a form accepted by the Company, in which the Option is to be passed to beneficiaries upon the death of the trustor (settlor) and (iii) by gift, in a form accepted by the Company, to a member of the "immediate family" of the Optionholder as that term is defined in 17 C.F.R. 240.16a-1(e). In addition, Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option. (e) VESTING. Options shall vest as follows: (i) Initial Grants shall provide for vesting of 1/60th of the shares subject to the Option each month after grant for five (5) years after the date of the grant. A-4 APPENDIX A (ii) Annual Grants shall provide for vesting of 1/12th of the shares subject to the Option each month after grant for twelve (12) months after the date of the grant. (f) TERMINATION OF CONTINUOUS SERVICE. In the event an Optionholder's Continuous Service terminates (other than upon the Optionholder's death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise it as of the date of termination) but only within such period of time ending on the earlier of (i) the date six (6) months following the termination of the Optionholder's Continuous Service, or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. (g) EXTENSION OF TERMINATION DATE. If the exercise of the Option following the termination of the Optionholder's Continuous Service (other than upon the Optionholder's death or Disability) would be prohibited at any time solely because the issuance of shares would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in subsection 7(a) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder's Continuous Service during which the exercise of the Option would not be in violation of such registration requirements. (h) DISABILITY OF OPTIONHOLDER. In the event an Optionholder's Continuous Service terminates as a result of the Optionholder's Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise it as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate. (i) DEATH OF OPTIONHOLDER. In the event (i) an Optionholder's Continuous Service terminates as a result of the Optionholder's death or (ii) the Optionholder dies within the three-month period after the termination of the Optionholder's Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise the Option as of the date of death) by the Optionholder's estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder's death, but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate. 8. COVENANTS OF THE COMPANY. (a) AVAILABILITY OF SHARES. During the terms of the Options, the Company shall keep available at all times the number of shares of Common Stock required to satisfy such Options. (b) SECURITIES LAW COMPLIANCE. The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Options and to issue and sell shares of Common Stock upon exercise of the Options; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Option or any stock issued or issuable pursuant to any such Option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Options unless and until such authority is obtained. 9. USE OF PROCEEDS FROM STOCK. Proceeds from the sale of stock pursuant to Options shall constitute general funds of the Company. A-5 APPENDIX A 10. MISCELLANEOUS. (a) STOCKHOLDER RIGHTS. No Optionholder shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such Option unless and until such Optionholder has satisfied all requirements for exercise of the Option pursuant to its terms. (b) NO SERVICE RIGHTS. Nothing in the Plan or any instrument executed or Option granted pursuant thereto shall confer upon any Optionholder any right to continue to serve the Company as a Non-Employee Director or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant's agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. (c) INVESTMENT ASSURANCES. The Company may require an Optionholder, as a condition of exercising or acquiring stock under any Option, (i) to give written assurances satisfactory to the Company as to the Optionholder's knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Option; and (ii) to give written assurances satisfactory to the Company stating that the Optionholder is acquiring the stock subject to the Option for the Optionholder's own account and not with any present intention of selling or otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (iii) the issuance of the shares upon the exercise or acquisition of stock under the Option has been registered under a then currently effective registration statement under the Securities Act or (iv) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock. (d) WITHHOLDING OBLIGATIONS. The Optionholder may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of stock under an Option by any of the following means (in addition to the Company's right to withhold from any compensation paid to the Optionholder by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares from the shares of the Common Stock otherwise issuable to the Optionholder as a result of the exercise or acquisition of stock under the Option, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to the Company owned and unencumbered shares of the Common Stock. 11. ADJUSTMENTS UPON CHANGES IN STOCK. (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the stock subject to the Plan, or subject to any Option, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of securities subject both to the Plan pursuant to subsection 4(a) and to the nondiscretionary Options specified in Section 5, and the outstanding Options will be appropriately adjusted in the class(es) and number of securities and price per share of stock subject to such outstanding Options. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction "without receipt of consideration" by the Company.) (b) CHANGE IN CONTROL -- DISSOLUTION OR LIQUIDATION. In the event of a dissolution or liquidation of the Company, then all outstanding Options shall terminate immediately prior to such event. A-6 APPENDIX A (c) CHANGE IN CONTROL -- ASSET SALE, MERGER, CONSOLIDATION OR REVERSE MERGER. (i) In the event of (i) a sale, lease or other disposition of all or substantially all of the assets of the Company, (ii) a merger or consolidation in which the Company is not the surviving corporation or (iii) a reverse merger in which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then any surviving corporation or acquiring corporation shall assume any Options outstanding under the Plan or shall substitute similar Options (including an option to acquire the same consideration paid to the stockholders in the transaction described in this subsection 11(c) for those outstanding under the Plan). (ii) In the event any surviving corporation or acquiring corporation refuses to assume such Options or to substitute similar Options for those outstanding under the Plan, then the vesting of such Options and the vesting of any shares of Common Stock acquired pursuant to such Options shall be accelerated in full, and the Options shall terminate if not exercised at or prior to such event. (iii) In the event any surviving corporation or acquiring corporation assumes such Options or substitutes similar Options for those outstanding under the Plan but the Optionholder is not elected or appointed to the board of directors of the surviving corporation or acquiring corporation at the first meeting of such board of directors after such change in control event, then the vesting of such Options and the vesting of any shares of Common Stock acquired pursuant to such Options shall be accelerated by eighteen (18) months on the day after the first meeting of the board of directors of the surviving corporation or acquiring corporation. (iv) In the event any surviving corporation or acquiring corporation assumes such Options or substitutes similar Options for those outstanding under the Plan and the Optionholder is elected or appointed to the board of directors of the surviving corporation or acquiring corporation at the first meeting of such board of directors after such change in control event, then the vesting of such Options and the vesting of any shares of Common Stock acquired pursuant to such Options shall not be accelerated. 12. AMENDMENT OF THE PLAN AND OPTIONS. (a) AMENDMENT OF PLAN. The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 11 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy the requirements of Rule 16b-3 or any Nasdaq or securities exchange listing requirements. (b) STOCKHOLDER APPROVAL. The Board may, in its sole discretion, submit any other amendment to the Plan for stockholder approval. (c) NO IMPAIRMENT OF RIGHTS. Rights under any Option granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Optionholder and (ii) the Optionholder consents in writing. (d) AMENDMENT OF OPTIONS. The Board at any time, and from time to time, may amend the terms of any one or more Options; provided, however, that the rights under any Option shall not be impaired by any such amendment unless (i) the Company requests the consent of the Optionholder and (ii) the Optionholder consents in writing. 13. TERMINATION OR SUSPENSION OF THE PLAN. (a) PLAN TERM. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on the day before the tenth (10th) anniversary of the date the Plan is adopted by the Board or A-7 APPENDIX A approved by the stockholders of the Company, whichever is earlier. No Options may be granted under the Plan while the Plan is suspended or after it is terminated. (b) NO IMPAIRMENT OF RIGHTS. Suspension or termination of the Plan shall not impair rights and obligations under any Option granted while the Plan is in effect except with the written consent of the Optionholder. 14. EFFECTIVE DATE OF PLAN. The Plan shall become effective on the IPO Date, but no Option shall be exercised unless and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board. 15. CHOICE OF LAW. All questions concerning the construction, validity and interpretation of this Plan shall be governed by the law of the State of Delaware, without regard to such state's conflict of laws rules.
