Proxy Statement for the 2007 Annual Meeting of Stockholders

To Be Held on May 30, 2007

This proxy statement contains information about the 2007 annual meeting of stockholders of Infinity Pharmaceuticals, Inc., including postponements and adjournments of the meeting. We are holding the meeting at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston, Massachusetts 02109 on Wednesday, May 30, 2007 at 10:00 a.m., local time.

We are sending you this proxy statement in connection with the solicitation of proxies by our board of directors for use at the annual meeting.

We are mailing our Annual Report to Stockholders for the year ended December 31, 2006 with these proxy materials on or about April     , 2007.

You can find our Annual Report on Form 10-K for the year ended December 31, 2006 on the Internet at our website, www.ipi.com, or through the Securities and Exchange Commission’s electronic data system, called EDGAR, at www.sec.gov. You may also obtain a printed copy of our Annual Report on Form 10-K, free of charge, from us by sending a written request to: Investor Relations, Infinity Pharmaceuticals, Inc., 780 Memorial Drive, Cambridge, Massachusetts 02139.

DPI MERGER

On September 12, 2006, we completed our reverse merger in which a wholly-owned subsidiary of Discovery Partners International, Inc. or DPI, merged with Infinity Pharmaceuticals, Inc., or IPI, such that IPI became a wholly-owned subsidiary of DPI. In that transaction, IPI changed its name to Infinity Discovery, Inc., which we refer to as Old Infinity. In addition, DPI changed its name to Infinity Pharmaceuticals, Inc., or Infinity. Upon completion of the merger, approximately 14.4 million shares of Infinity common stock were issued to Old Infinity stockholders in exchange for their shares of Old Infinity capital stock, and Infinity assumed all of the stock options and warrants of Old Infinity outstanding as of September 12, 2006. Immediately following the closing of the merger, former Old Infinity stockholders, option holders and warrant holders owned approximately 69% of the combined company on a fully-diluted basis and former DPI stockholders, option holders and warrant holders owned approximately 31% of the combined company on a fully-diluted basis. After completion of the merger, the business conducted by the combined company became the one operated by Old Infinity prior to the merger. In addition, former Old Infinity directors constitute a majority of our current board of directors and all members of our current management team are from Old Infinity. Therefore, except as specifically identified, the information contained in this proxy statement with respect to periods prior to the merger reflects the business of Old Infinity, and not DPI, and the information contained in this proxy statement with respect to periods following the merger reflects the business of the combined company. Further, the terms “Infinity,” “we,” “us,” and “our” refer to the combined company after the merger, while “Old Infinity” refers to IPI prior to completion of the merger and “DPI” refers to Discovery Partners International, Inc. prior to completion of the merger.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

 

Q.    Who can vote at the annual meeting?    A.   

To be able to vote, you must have been a stockholder of record at the close of business on April 2, 2007, the record date for our annual meeting. The number of outstanding shares entitled to vote at the meeting is            shares of common stock.

 

If you were a stockholder of record on that date, you will be entitled to vote all of the shares that you held on that date at the meeting, or any postponements or adjournments of the annual meeting.

Q.    What are the voting rights of the holders of common stock?    A.    Each outstanding share of our common stock will be entitled to one vote on each matter considered at the annual meeting.
Q.    How do I vote?    A.    If you are a record holder, meaning your shares are registered in your name, you may vote:
        

(1)    By Submitting a Proxy Over the Internet or by Telephone: Follow the instructions on the enclosed proxy card to vote by accessing www.proxyvote.com or calling 1-800-690-6903. You must specify how you want your shares voted. Your shares will be voted according to your instructions.

        

(2)    By Submitting a Proxy By Mail: Complete and sign your enclosed proxy card and return it by mail in the enclosed postage prepaid envelope. Your shares will be voted according to your instructions. If you do not specify how you want your shares voted, they will be voted as recommended by our board of directors.

        

(3)    In Person at the Meeting: If you attend the meeting, you may deliver your completed proxy card in person or you may vote by completing a ballot, which we will provide to you at the meeting.

         If your shares are held in “street name,” meaning they are held for your account by a broker or other nominee, you may vote:
        

(1)    By Submitting Voting Instructions Over the Internet or by Telephone: You will receive instructions from your broker or other nominee if they permit Internet or telephone voting instructions. You should follow those instructions.

        

(2)    By Submitting Voting Instructions By Mail: You will receive instructions from your broker or other nominee explaining how you can submit voting instructions for your shares by mail. You should follow those instructions.

        

(3)    In Person at the Meeting: Contact your broker or other nominee who holds your shares to obtain a brokers’ proxy card and bring it with you to the meeting. You will not be able to vote in person at the meeting unless you have a proxy from your broker issued in your name giving you the right to vote your shares.

Q.    Can I change my vote?    A.    Yes. You may revoke your proxy and change your vote at any time before the meeting. To do so, you must do one of the following:
        

(1)    Submit a proxy over the Internet or by telephone as instructed above. Only your latest Internet or telephone proxy is counted.

 

2


Table of Contents
        

(2)    Sign a new proxy and submit it as instructed above. Only your latest dated proxy will be counted.

        

(3)    Attend the meeting, request that your proxy be revoked and vote in person as instructed above. Attending the meeting will not revoke your proxy unless you specifically request it.

Q.    Will my shares be voted if I don’t return my proxy?    A.    If your shares are registered directly in your name, your shares will not be voted if you do not submit a proxy over the Internet or by telephone, return your proxy or vote by ballot at the meeting. If your shares are held in “street name,” your brokerage firm may, under certain circumstances, vote your shares if you do not return your proxy. Brokerage firms can vote customers’ unvoted shares on routine matters. If you do not return a proxy to your brokerage firm to vote your shares, your brokerage firm may, on routine matters, either vote your shares or return a proxy but leave your shares unvoted. Your brokerage firm cannot vote your shares on any matter that is not considered routine.
         Proposal 1, the election of directors, and Proposal 4, the ratification of the selection of our independent registered public accounting firm, are both considered routine matters. However, Proposal 2, amendment and restatement of the certificate of incorporation, and Proposal 3, amendment of the by-laws, are not considered routine matters. We encourage you to provide voting instructions to your brokerage firm by giving your proxy to your brokerage firm. This ensures that your shares will be voted at the meeting according to your instructions. You should receive directions from your brokerage firm about how to submit your proxy to your brokerage firm at the time you receive this proxy statement.
Q.    How many shares must be present to hold the meeting?    A.   

A majority of our outstanding shares of common stock must be present at the meeting to hold the meeting and conduct business. This is called a quorum. For purposes of determining whether a quorum exists, we count as present any shares that are represented by proxy or that are represented in person at the meeting. For purposes of establishing a quorum, we will count as present shares that a stockholder holds even if the stockholder votes to abstain or does not vote on one or more of the matters to be voted upon.

 

If a quorum is not present, we expect to adjourn the meeting until we obtain a quorum.

Q.    What vote is required to approve each matter and how are votes counted?    A.   

Proposal 1—Election of four Class I directors

 

To elect any of the nominees for director, stockholders holding a majority of the shares of our common stock present in person or represented by proxy and entitled to vote must vote FOR such nominee. You may:

        

•       vote FOR all four nominees;

 

•       vote FOR one or more nominees and WITHHOLD your vote from the remaining nominees; or

 

•       WITHHOLD your vote from all four nominees.

 

If your shares are held by your broker in street name, and you do not vote your shares, your brokerage firm may vote your unvoted shares on Proposal 1 or leave your shares unvoted. Broker non-votes are not voting power present and, therefore, will have no effect on the outcome of voting on this matter. Absentions are voting power present and, therefore, will have the effect of a vote against this matter.

 

3


Table of Contents
         Proposal 2—Amendment and Restatement of the Certificate of Incorporation
         To approve Proposal 2, stockholders holding a majority of our outstanding shares of common stock on the record date must vote FOR the proposal. Proposal 2 is not considered a routine matter. Therefore, if your shares are held by your broker in street name, and you do not vote your shares, your brokerage firm cannot vote your shares on Proposal 2. Shares held in street name by brokers or nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 2 will not be counted as votes cast or shares voting on the proposal. If you vote to ABSTAIN on Proposal 2, your shares will not be voted for or against the proposal and will also not be counted as votes cast or shares voting on the proposal. As a result, broker non-votes and votes to ABSTAIN will have the same effect as votes against the proposal.
         Proposal 3—Amendment of the By-laws
         To approve Proposal 3, stockholders holding 66 2/3% of our outstanding shares of common stock on the record date must vote FOR the proposal. Proposal 3 is not considered a routine matter. Therefore, if your shares are held by your broker in street name, and you do not vote your shares, your brokerage firm cannot vote your shares on Proposal 3. Shares held in “street name” by brokers or nominees who indicate on their proxies that they do not have authority to vote the shares on Proposal 3 will not be counted as votes in favor of or against the proposal, and will also not be counted as votes cast or shares voting on the proposal. If you vote to ABSTAIN on Proposal 3, your shares will not be voted for or against the proposal and will also not be counted as votes cast or shares voting on the proposal. As a result, broker non-votes and votes to ABSTAIN will have the same effect as votes against the proposal.
         Proposal 4—Ratification of Selection of Independent Registered Public Accounting Firm
         To approve Proposal 4, stockholders holding a majority of the shares of our common stock present in person or represented by proxy at the meeting and entitled to vote must vote FOR the proposal. If your shares are held by your broker in street name, and you do not vote your shares, your brokerage firm may vote your unvoted shares on Proposal 4. Broker non-votes are not voting power present and, therefore, will have no effect on the outcome of voting on this matter. Absentions are voting power present and, therefore, will have the effect of a vote against this matter.
         Although stockholder approval of our Audit Committee’s selection of Ernst & Young LLP as our independent registered public accounting firm is not required, we believe that it is advisable to give stockholders an opportunity to ratify this selection. If this proposal is not approved at the annual meeting, our Audit Committee will reconsider its selection of Ernst & Young LLP.
Q.    Are there other matters to be voted on at the meeting?    A.    We do not know of any other matters that may come before the meeting other than the election of four Class I directors, the approval of the amendment and restatement of our certificate of incorporation, the approval of the amendment of our by-laws and the ratification of the selection of our

Table of Contents
         independent registered public accounting firm. If any other matters are properly presented at the meeting, the persons named in the accompanying proxy intend to vote, or otherwise act, in accordance with their judgment on the matters.
Q.    Where can I find the voting results?    A.    We expect to report the voting results in our Quarterly Report on Form 10-Q for the quarter ending June 30, 2007, which we anticipate filing with the Securities and Exchange Commission in August 2007.
Q.    What are the costs of soliciting these proxies?    A.    We will bear the cost of soliciting proxies. In addition to these proxy materials, our directors, officers and employees may solicit proxies by telephone, e-mail, facsimile and in person, without additional compensation. Upon request, we will reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for distributing proxy materials.

Delivery of Security Holder Documents

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our proxy statement and annual report to stockholders may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you if you write or call us at the following address or telephone number: 780 Memorial Drive, Cambridge, Massachusetts 02139, Attention: Investor Relations; 617-453-1254. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy for your household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and telephone number.

Stock Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information, as of December 31, 2006, or such other date as indicated below, with respect to the beneficial ownership of our common stock by:

 

   

each person whom we know beneficially owns more than 5% of the outstanding shares of our common stock;

 

   

each of our directors and nominees for director;

 

   

each of our executive officers named below under the heading “Compensation of Executive Officers and Directors—Summary Compensation Table”; and

 

   

all of our directors and executive officers as a group.

The number of shares of our common stock owned by each person is determined under the rules of the Securities and Exchange Commission, or SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under these rules, beneficial ownership includes any shares as to which the individual has sole or shared voting power or investment power and also any shares which the individual has the right to acquire within 60 days after December 31, 2006 through the exercise of any stock option or other right. Unless otherwise indicated, each person has sole voting and investment power, or shares such power with his or her spouse, with respect to the shares set forth in the following table. The inclusion in this table of any shares deemed beneficially owned does not constitute an admission of beneficial ownership of those shares.

Unless otherwise indicated, the address for each person is to the care of Infinity Pharmaceuticals, Inc., 780 Memorial Drive, Cambridge, Massachusetts 02139.

CORPORATE GOVERNANCE

General

This section describes key corporate governance guidelines and practices that we have adopted. Complete copies of our corporate governance guidelines, committee charters and code of business conduct and ethics described below are available on our website, www.ipi.com. Alternatively, you can request a copy of any of these documents by writing to: Investor Relations, Infinity Pharmaceuticals, Inc., 780 Memorial Drive, Cambridge, Massachusetts 02139. Our board of directors believes that good corporate governance is important to ensure that Infinity is managed for the long-term benefit of our stockholders.

Corporate Governance Guidelines

Our board of directors has adopted corporate governance guidelines to assist the board in the exercise of its duties and responsibilities and to serve the best interests of Infinity and our stockholders. These guidelines, which provide a framework for the conduct of the board’s business, provide that:

 

   

the principal responsibility of the directors is to oversee our management;

 

   

a majority of the members of the board shall be independent directors, unless otherwise permitted by Nasdaq rules;

 

   

the independent directors meet at least twice a year and at other times at the request of any independent director;

 

   

directors have full and free access to management and, as necessary and appropriate, independent advisors; and

 

   

at least annually, the board and its committees will conduct a self-evaluation to determine whether they are functioning effectively.

Board Determination of Independence

Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of our board of directors, that person does not have a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our board of directors has determined that none of Messrs. Daniel, Lee or Rosenman or Drs. Evnin, Hixson, Lander, Levine, Moss, Sato or Tananbaum has a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under Rule 4200(a)(15) of the Nasdaq Stock Market, Inc. Marketplace Rules.

Director Nomination Process

The process followed by the independent members of our board to identify and evaluate candidates includes requests to independent directors and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the board.

In considering whether to recommend to our board of directors any particular candidate for inclusion in the board’s slate of recommended director nominees, including candidates recommended by stockholders, the independent members of our board apply the criteria as set forth in our corporate governance guidelines. These criteria include the candidate’s integrity, business acumen, knowledge of our business and industry, experience, diligence, conflicts of interest and the ability to act in the interests of all stockholders. The independent members of our board do not assign specific weights to particular criteria and no particular criterion is a prerequisite for each nominee. We believe that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the board to fulfill its responsibilities.

Table of Contents

Stockholders may recommend individuals to the independent members of our board for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made to the independent members of our board, c/o Gerald E. Quirk, Esq., Vice President and General Counsel, Infinity Pharmaceuticals, Inc., 780 Memorial Drive, Cambridge, Massachusetts 02139. Assuming that appropriate biographical and background material is provided for candidates recommended by stockholders, the independent members of our board will evaluate those candidates by following substantially the same process, and applying substantially the same criteria, as for candidates submitted by others.

Our stockholders also have the right to nominate director candidates themselves, without any prior review or recommendation by the independent members of our board or the full board of directors, by following the procedures set forth under “Stockholder Proposals for the 2008 Annual Meeting.”

At the annual meeting, stockholders will be asked to consider the election of Mr. Rosenman and Drs. Lander, Moss and Tananbaum, each of whom is being nominated for re-election to the board.

Board Meetings and Attendance

Our board of directors currently consists of the 12 directors listed under Proposal 1 above. Prior to the closing of the merger, the board of directors of DPI consisted of five directors: Sir Colin T. Dollery, FmedSci, Harry F. Hixson, Jr., Ph.D., Alan J. Lewis, Ph.D., Herm Rosenman and Michael C. Venuti, Ph.D. Sir Dollery and Dr. Lewis resigned from the board of directors of DPI immediately prior to the closing of the merger.

Our board of directors held 12 meetings, either in person or by teleconference, during the year ended December 31, 2006, or “Fiscal 2006”. Of the 12 meetings our board of directors held in Fiscal 2006, nine were held prior to the closing of the merger and three were held after the closing of the merger. During Fiscal 2006, each director attended at least 75% of the aggregate of the number of board meetings and the number of meetings held by all committees on which he or she then served, except that each of Dr. Levine and Dr. Sato attended two of the three meetings, or 67% of the meetings, of our board of directors held after the closing of the merger, the period of time during which they served on our board of directors. Neither Dr. Levine nor Dr. Sato served on any committees of our board of directors during Fiscal 2006. Dr. Lander attended two of the three meetings of our board of directors and was absent from the one meeting of our Corporate Governance Committee held after the closing of the merger, the period of time during which he served on our board of directors and Corporate Governance Committee. As such, Dr. Lander attended 50% of the aggregate of the number of board meetings and committee meetings on which he then served. Drs. Lander, Levine and Sato were each absent from the same meeting of the board of directors, which meeting was previously unplanned and was scheduled on short notice to approve matters incident to the filing of our quarterly report on Form 10-Q for the quarter ended September 30, 2006.

Director Attendance at Annual Meeting of Stockholders

We do not have a policy with regard to board members’ attendance at annual meetings.

All of the directors of DPI who were serving at the time of the 2006 annual meeting of stockholders of DPI attended the 2006 annual meeting of stockholders of DPI.

Board Committees

Our board of directors currently has three standing committees—Audit, Compensation and Corporate Governance.

In connection with the closing of the merger, our board of directors determined that Dr. Moss’s membership on the compensation committee was in the best interest of Infinity and its stockholders based on his individual qualifications and his membership on the board of directors of Old Infinity.

Prior to the closing of the merger, the members of the Compensation Committee of the board of directors of DPI were Dr. Lewis (Chairman), Sir Dollery and Dr. Hixson.

The Compensation Committee held nine meetings during 2006.

The Compensation Committee is authorized to retain advisors and consultants and to compensate them for their services.

Prior Nominating and Corporate Governance Committee

Prior to the closing of the merger, the board of directors of DPI had a Nominating and Corporate Governance Committee, which was comprised of Drs. Hixson (Chairman) and Lewis and Mr. Rosenman.

Effective upon the closing of the merger, the board of directors established a Corporate Governance Committee, and since that time, the board of directors has not had a committee that performs the function of nominating directors. The board of directors believes that it is appropriate to not have a nominating committee because the independent members of our board of directors are capable of identifying and evaluating candidates to serve on our board of directors and selecting director nominees. Our board of directors may from time to time consider whether to establish a nominating committee. The independent members of our board of directors, Messrs. Daniel, Lee and Rosenman and Drs. Evnin, Hixson, Lander, Levine, Moss, Sato and Tananbaum, participate in the current procedure for nominating directors to our board as set forth above under the heading “Director Nomination Process.” Because Mr. Holtzman, our chair and chief executive officer, and Dr. Venuti, who served as an officer of DPI prior to the merger, are not independent directors, they do not participate in the nomination of directors.

The Nominating and Corporate Governance Committee of the board of directors of DPI held two meetings in 2006 prior to the closing of the merger.

Current Corporate Governance Committee

Our Corporate Governance Committee has the following principal responsibilities:

 

   

developing and recommending to the board corporate governance principles; and

 

   

overseeing annual evaluations of the board.

The current members of the Corporate Governance Committee are Drs. Tananbaum (Chair), Hixson, Lander and Venuti.

Executive and Director Compensation Processes

The Compensation Committee of our board of directors oversees our compensation program. In this role, the Compensation Committee determines and, after consultation with the entire board of directors, approves annually all compensation decisions relating to our executive officers.

In addition, in accordance with its charter, our Compensation Committee periodically reviews and makes recommendations to the board of directors with respect to director compensation.

The following is an overview of our processes and procedures for the consideration and determination of executive compensation. For a more detailed discussion of executive compensation, including our processes and procedures for the consideration and determination of executive compensation, please see “Compensation Discussion and Analysis” beginning on page 24 below.

Annually, our approximately 20-member leadership team prepares and submits for approval by the board of directors a set of annual corporate goals. Upon ratification of the overall corporate goals, typically in the first quarter of each calendar year, departmental and individual goals are set focusing on contributions that facilitate the achievement of these company goals.

The same approximately 20-member leadership team, on an annual basis, typically around the first of the year, then evaluates company performance against the goals for the recently completed year. This assessment by the leadership team is then presented to the Compensation Committee for its review. The Compensation Committee has the discretion to determine that company performance against goals was achieved at a level other than the one recommended by our leadership team. The Compensation Committee may review, and historically has reviewed, its assessment with the board of directors, although it is not required to do so. In addition to evaluating company performance, during the first quarter of each year, we evaluate individual performance for the recently completed year. In the case of our executive officers, Dr. Adams and Ms. Perkins submit their respective self-assessments to Mr. Holtzman, who prepares their written assessments. Mr. Holtzman prepares a written self-assessment and submits it to the chair of the Compensation Committee, who prepares an evaluation of Mr. Holtzman’s performance.

The following is a discussion of certain authority that the Compensation Committee has delegated to a committee and the authority of the Compensation Committee with respect to compensation consultants.

The Compensation Committee has delegated to the Stock Option Administration Committee, comprised solely of Mr. Holtzman, our Chief Executive Officer, the authority to grant stock options and restricted stock under our 2000 Stock Incentive Plan, subject to the following limitations. The Stock Option Administration Committee is not authorized to: (a) grant options or restricted stock to our executive officers, (b) grant to any person, in any one calendar year, options and/or restricted stock with respect to more than 50,000 shares of our common stock, (c) grant in the aggregate in any one fiscal quarter, options and/or restricted stock with respect to more than 250,000 shares of our common stock or (d) grant options with an exercise price, or restricted stock with a purchase price, that is below the fair market value of our common stock on the date of grant (as determined under our 2000 Stock Incentive Plan). The Stock Option Administration Committee must report to the Compensation Committee on a quarterly basis regarding the options and restricted stock granted during the prior quarter.

The Compensation Committee has the authority to retain compensation consultants and other outside advisors to assist in the evaluation of executive officer compensation.

Communicating with the Independent Directors

Our board of directors will give appropriate attention to written communications that are submitted by stockholders and other interested parties, and will respond if and as appropriate. Our Lead Outside Director is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the other directors as she considers appropriate. Dr. Sato currently serves as our Lead Outside Director.

Under procedures approved by a majority of the independent directors, communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the Lead Outside Director considers to be important for the directors to know. In general, communications relating to corporate governance and corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

Stockholders who wish to send communications on any topic to the board of directors should address such communications to Board of Directors, c/o Gerald E. Quirk, Esq., Vice President and General Counsel, Infinity Pharmaceuticals, Inc., 780 Memorial Drive, Cambridge, MA 02139, or by email to contactboard@ipi.com.

Code of Business Conduct and Ethics

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer and controller, or persons performing similar functions. We have posted a copy of the code on our website, www.ipi.com. In addition, we intend to post on our website all disclosures that are required by law or Nasdaq Stock Market listing standards concerning any amendments to, or waivers of, our code.

Audit-Related Matters

On September 12, 2006, we completed our reverse merger in which DPI merged with Old Infinity, such that Old Infinity became a wholly-owned subsidiary of DPI, which changed its name to Infinity Pharmaceuticals, Inc. After completion of the merger, the business conducted by the combined company became the one operated by Old Infinity prior to the merger. Since former Old Infinity security holders owned, immediately following the merger, approximately 69% of the combined company on a fully-diluted basis, and as a result of certain other factors, including that former Old Infinity directors constituted a majority of the combined company’s board of directors and all members of the combined company’s executive management were from Old Infinity, Old Infinity was deemed to be the acquiring company for accounting purposes and the transaction was accounted for as a reverse acquisition of assets and a recapitalization in accordance with accounting principles generally accepted in the United States. Accordingly, for all purposes, including SEC reporting, our financial statements for periods prior to the merger reflect the historical results of Old Infinity, and not DPI, and our financial statements for all subsequent periods reflect the results of the combined company. Therefore, the sections below entitled “Report of the Audit Committee” and “Auditors’ Fees” relate to the audits of the financial statements of Old Infinity for periods prior to the completion of the merger.

Report of the Audit Committee

The Audit Committee has reviewed our audited financial statements for the fiscal year ended December 31, 2006 and has discussed these financial statements with our management and independent registered public accounting firm.

The Audit Committee has also received from, and discussed with, Ernst & Young LLP, our independent registered public accounting firm, various communications that our independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (Communication with Audit Committees).

Our independent registered public accounting firm also provided the Audit Committee with the written disclosures and the letter required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). The Audit Committee has discussed with the independent registered public accounting firm its independence from Infinity.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to our board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2006.

Severance Agreement with Michael C. Venuti, Ph.D.

On April 19, 2006, DPI approved an executive retention and severance agreement with Michael C. Venuti, Ph.D., the Acting Chief Executive Officer of DPI at the time, under which he was entitled to receive a retention bonus consisting of a cash amount of up to $25,000, which amount became due and was paid by us upon the completion of the merger. In addition, the executive retention and severance agreement with Dr. Venuti entitled him to the acceleration in full of the vesting of 50,000 shares of restricted stock held by Dr. Venuti upon the completion of the merger, the value of which acceleration is identified as $752,000 in the Option Exercises and Stock Vested Table located below under the heading “Compensation of Executive Officers and Directors.” In addition, in connection with the merger, Dr. Venuti received $379,363 in severance and change-in-control payments.

License Agreement with Amgen Inc.

On July 7, 2006, Old Infinity entered into a license agreement with Amgen Inc., or Amgen, who, at the time of execution of the agreement, was a holder of more than 5% of the outstanding shares of capital stock of Old Infinity, and who was, as of December 31, 2006, a holder of more than 5% of the outstanding shares of our common stock. Pursuant to, and in accordance with the terms of, the license agreement, we have granted to Amgen a non-exclusive worldwide license to use a proprietary collection of small molecules in its internal drug discovery activities. Amgen has paid us a $2.5 million upfront license fee and has agreed to make milestone payments of up to an aggregate of $31.35 million for each product that Amgen develops and successfully commercializes based upon a licensed compound, assuming that Amgen achieves specified clinical and regulatory objectives. Amgen has also agreed to make additional milestone payments of up to an aggregate of $12.0 million for each product that Amgen develops and successfully commercializes based upon a specified subset of the licensed compounds, assuming that Amgen achieves specified clinical and regulatory objectives for those licensed compounds. Finally, Amgen has agreed to make success payments totaling up to an aggregate of $6.0 million if Amgen achieves specified research and/or intellectual property objectives and to pay royalties on sales of any products. Subject to earlier termination in accordance with the terms of the agreement, the agreement will expire upon the later of Amgen’s permanent cessation of all research and development activities under the agreement or the expiration of the final royalty term, unless earlier terminated.

Collaboration Agreement with Novartis Institutes for BioMedical Research, Inc.

On February 24, 2006, Old Infinity entered into a collaboration agreement with Novartis Institutes for BioMedical Research, Inc., or Novartis, to discover, develop and commercialize drugs targeting Bcl protein

family members for the treatment of a broad range of cancer indications. At the time of execution of the agreement, Novartis AG, an affiliate of Novartis, was the beneficial owner of more than 5% of the outstanding shares of capital stock of Old Infinity, and, as of December 31, 2006, Novartis AG was the beneficial owner of more than 5% of the outstanding shares of our common stock. Under the terms of the agreement, we have granted to Novartis an exclusive, worldwide license to research, develop and commercialize pharmaceutical products that are based upon our proprietary Bcl inhibitors. Novartis paid us $15.0 million in upfront license fees and has committed research funding of approximately $10.0 million during the initial two-year research term. The research term may be extended for up to two additional one-year terms at the discretion of Novartis, and Novartis will agree to fund additional research during any extension period in an amount to be agreed upon. Assuming that the strategic alliance continues for its full term and specified research, development and commercialization milestones are achieved for multiple products for multiple indications, Novartis has agreed to make milestone payments totaling over $370.0 million, such that total payments to us could exceed $400.0 million. In addition, Novartis has agreed to pay us royalties upon successful commercialization of any products developed under the alliance. In connection with the agreement, Novartis Pharma AG purchased a specified number of shares of preferred stock of Old Infinity, which were converted into 266,310 shares of our common stock upon the closing of the merger. Pursuant to the agreement, we are conducting joint research with Novartis to identify molecules for clinical development. Novartis will have responsibility for clinical development and commercialization of any products based upon compounds discovered under the joint research program. However, we may request to participate in clinical development and if such request is agreed upon by Novartis, then Novartis will fund agreed-upon development costs incurred by us. We also have a non-exclusive right to detail Bcl-2 family inhibitor products in the United States, with our detailing costs to be reimbursed by Novartis.

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

Our board has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which we are a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a “related person,” has a direct or indirect material interest.

If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a “related person transaction,” the related person must report the proposed related person transaction to our general counsel. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by the Audit Committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chair of the committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to ratification by the committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.

A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the committee will review and consider:

 

   

the related person’s interest in the related person transaction;

 

   

the approximate dollar value of the amount involved in the related person transaction;

 

   

the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;

 

   

whether the transaction was undertaken in the ordinary course of our business;

 

   

whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;

 

22


Table of Contents
   

the purpose of, and the potential benefits to us of, the transaction; and

 

   

any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

The committee may approve or ratify the transaction only if the committee determines that, under all of the circumstances, the transaction is not inconsistent with our best interests. The committee may impose any conditions on the related person transaction that it deems appropriate.

In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, our board of directors has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

 

   

interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, (b) the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction and do not receive any special benefits as a result of the transaction, and (c) the amount involved in the transaction equals less than the greater of $200,000 dollars or 5% of the annual consolidated gross revenues of the other entity that is a party to the transaction; and

 

   

a transaction that is specifically contemplated by provisions of our charter or bylaws.

The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.

COMPENSATION OF EXECUTIVE OFFICERS AND DIRECTORS

Compensation Discussion and Analysis

The Compensation Committee of our board of directors oversees our compensation program. In this role, the Compensation Committee determines and, after consultation with the entire board of directors, approves annually all compensation decisions relating to our executive officers.

Our Executive Officers

Our current executive officers are Steven H. Holtzman, Chair and Chief Executive Officer, Julian Adams, Ph.D., President and Chief Scientific Officer, and Adelene Q. Perkins, Executive Vice President and Chief Business Officer, all of whom were executive officers of Old Infinity. In the executive compensation tables below, pursuant to the requirements of the proxy disclosure rules of the SEC, we also include information with respect to the following former officers of DPI: Michael C. Venuti, Ph.D., Craig Kussman, Douglas A. Livingston, Ph.D. and Richard C. Neale. For a further discussion of the compensation of the executive officers of Old Infinity and DPI, please see “—Transactions Associated with the DPI Merger” beginning on page 31 below.

Objectives and Philosophy of our Compensation Program

The primary objectives of the Compensation Committee with respect to compensation for all of our employees (whom we call citizen-owners) are to:

 

   

attract, retain and motivate the highest caliber scientists and business people to develop and execute our business plan;

 

   

ensure that compensation aligns our citizen-owners with our corporate strategy and business objectives;

 

   

promote the achievement of key scientific, business, organizational and operational goals by linking contingent cash compensation and long-term equity incentives to the achievement of these goals; and

 

   

align incentives with the creation of shareholder value.

To achieve these objectives, the Compensation Committee evaluates our compensation program with the goal of setting compensation at levels the committee believes are competitive with those of other companies in our industry that compete with us for talent. In addition, our compensation program ties a substantial portion of our executive officers’ overall compensation to key scientific, business, organizational and operational goals such as:

 

   

progress in our clinical trials and research programs;

 

   

implementation of appropriate financing strategies;

 

   

establishment of value-creating strategic alliances;

 

   

addition and development of internal competencies and retention of high-performing citizen-owners; and

 

   

achievement of desired financial performance.

We also provide a portion of our compensation in the form of stock options that vest over time. We believe this helps to retain our citizen-owners, including our executive officers, and aligns their interests with those of our non-employee stockholders by allowing them to participate in the longer term success of our company as reflected in stock price appreciation.

 

24


Table of Contents

In making compensation decisions regarding our executive officers, the Compensation Committee compares our executive compensation with the compensation of executives in similar roles in peer companies. We obtain this information through biopharmaceutical industry compensation surveys such as the Radford 2006 Biotechnology Survey and, for publicly-traded companies, SEC filings. In addition, following completion of the merger, our management recommended to the Compensation Committee that, in light of the fact that our citizen-owners were now part of a larger company with publicly-traded stock, the form and structure of our overall compensation program be reassessed. In particular, management recommended that our compensation program be evaluated by reference to a peer group of publicly traded companies in the biotechnology industry. The Compensation Committee believes that this peer group of companies is generally comparable to us by virtue of their similar size, geographic location, market capitalization, stage of development or oncology focus, or some combination of the foregoing, and that we could be competitors with many of these companies for executive talent. The companies included in this peer group are:

 

•       Anadys Pharmaceuticals, Inc.

 

•       Array BioPharma, Inc.

 

•       Coley Pharmaceutical Group, Inc.

 

•       CombinatorX, Inc.

 

•       Curis, Inc.

 

•       Cytokinetics, Inc.

 

•       Idenix Pharmaceuticals, Inc.

 

•       Memory Pharmaceuticals Corp.

 

•       Micromet, Inc.

 

•       Momenta Pharmaceuticals, Inc.

 

•       Novacea, Inc.

 

•       Pharmion Corp.

 

•       Renovis, Inc.

 

•       Santarus, Inc.

 

•       Sunesis Pharmaceuticals, Inc.

 

•       Targacept, Inc.

 

•       Vanda Pharmaceuticals, Inc.

 

•       Xenoport, Inc.

We have not retained a compensation consultant to review our policies and procedures with respect to executive compensation. Our Compensation Committee’s charter, however, expressly authorizes the Compensation Committee to retain and terminate any compensation consultant and to approve the fees and other terms associated with the engagement of such compensation consultant.

Performance Evaluation Process

Annually, our approximately 20-member leadership team prepares and submits for approval by the board of directors a set of annual corporate goals. These corporate goals are directed to specific scientific, business, organizational and operational objectives and represent, in many cases, “stretch” goals that may prove difficult to achieve. Upon ratification of the overall corporate goals, typically in the first quarter of each calendar year, departmental and individual goals are set focusing on contributions that facilitate the achievement of these company goals.

For 2006, our company goals included:

 

   

advancing our product development pipeline, including completion of Phase I clinical trials of IPI-504, our lead product candidate which targets heat shock protein 90, or Hsp90, and filing an investigational new drug application for a lead compound targeting the Hedgehog cell-signaling pathway, or the Hedgehog pathway;

 

   

effectively executing under our technology access alliances;

 

   

entering into a strategic alliance around one of our key product development programs; and

 

   

ending the year with sufficient cash to fund operations for between one and two years.

 

25


Table of Contents

The same approximately 20-member leadership team, on an annual basis, typically around the end of the year, then evaluates company performance against the goals for that year. With respect to company performance, our leadership team conducts a qualitative and quantitative assessment of the company’s overall performance against goals at one of the following levels:

 

   

below industry standards, or performance that neither resulted in the achievement of the stated goals, nor was consistent with performance that should reasonably be expected of a biotechnology company of comparable size, resources or stage of development;

 

   

met industry standards, or performance that resulted in the stated goals substantially being met and which was consistent with performance that should reasonably be expected of a biotechnology company of comparable size, resources and stage of development;

 

   

met Infinity expectations, or performance that exceeded industry standards and met essentially all of our goals (including some “stretch” goals) and exceeded some of them, with any failure to achieve a major goal being the result of factors outside of our reasonable control; and

 

   

exceeded Infinity expectations, or performance that far exceeded industry standards and resulted in our goals largely being exceeded.

This assessment by the leadership team is then presented to the Compensation Committee for its review. The Compensation Committee has the discretion to determine that company performance against goals was achieved at a level other than the one recommended by our leadership team. The Compensation Committee may review, and historically has reviewed, its assessment with the board of directors, although it is not required to do so.

In January 2007, the Compensation Committee determined that we performed in a manner that “exceeded Infinity expectations” during 2006, and that we did so convincingly. In making this determination, the Compensation Committee considered the following achievements:

 

   

IPI-504 being well tolerated in two Phase I clinical trials, with promising evidence of biological activity in our clinical trial of IPI-504 in patients with refractory gastrointestinal stromal tumors being presented in November 2006;

 

   

advancing a lead compound in our Hedgehog pathway inhibitor program to a point where an investigational new drug application could be filed, and deciding to defer filing that application until more potent, second-generation compounds could be evaluated for potential clinical development;

 

   

renewal of our technology access alliance with Amgen Inc. in July 2006, completion of our obligations under our technology access alliance with Johnson & Johnson, and successful performance under our technology access alliance with Novartis International Pharmaceuticals Ltd.;

 

   

entry into a worldwide alliance with the Novartis Institutes for BioMedical Research around our Bcl-2 program in February 2006;

 

   

entry into a worldwide alliance with MedImmune, Inc. around our Hsp90 and Hedgehog pathway programs in August 2006;

 

   

completing the DPI merger in September 2006;

 

   

enhancing our capabilities in clinical and pharmaceutical development, toxicology, finance, legal and corporate communications; and

 

   

ending the year with over three years of cash to fund operations, absent additional financings or business development activity.

In addition to evaluating company performance, during the first quarter of each year, we evaluate individual contributions for the recently completed year. Each citizen-owner’s evaluation begins with a written self-

 

26


Table of Contents

assessment, which is submitted to that citizen-owner’s manager. The manager solicits input from others within and/or outside of our company and then prepares a written performance review representing the manager’s assessment of the citizen-owner’s annual performance. In the case of our executive officers, Dr. Adams and Ms. Perkins submit their respective self-assessments to Mr. Holtzman, who prepares their written performance reviews. Mr. Holtzman prepares a written self-assessment and submits it to the chair of the Compensation Committee, who prepares an evaluation of Mr. Holtzman’s performance based on the company’s performance against its goals, Mr. Holtzman’s performance in providing leadership of the company in the pursuit of these goals, Mr. Holtzman’s performance in providing mentorship to the other executive officers, and, finally, Mr. Holtzman’s progress against his personal and professional development goals.

Components of our Compensation Program

The primary elements of our compensation program are:

 

   

cash compensation, which includes base salary and discretionary annual cash bonuses, which we refer to as contingent cash compensation;

 

   

annual merit stock option awards;

 

   

employee benefits, such as insurance and a 401(k) savings plan; and

 

   

severance benefits.

Each of these elements, other than severance benefits, is available to all of our citizen-owners generally, although the amounts of contingent cash compensation and the size of annual merit stock option awards differ from person to person based on such citizen-owner’s role and tenure in that role, market-competitive compensation, and his or her individual performance.

We do not have any formal or informal policy or target for allocating compensation between long-term and short-term compensation, between cash and non-cash compensation, or among the different forms of non-cash compensation. Instead, the Compensation Committee, after reviewing relevant information, determines subjectively what it believes to be the appropriate level and mix of the various compensation components.

Cash Compensation

Our cash compensation program comprises two elements: base salary and contingent cash compensation. Base salary is used to recognize the experience, skills, knowledge and responsibilities required of each of our citizen-owners, including each of our executive officers. Contingent cash compensation is used to reward the achievement of company and individual goals. The sum of base salary and contingent cash compensation constitutes total cash compensation. For a year in which company performance is equivalent to what should reasonably be expected of a biotechnology company of comparable size, resources and stage of development, the Compensation Committee believes that the average total cash compensation for our citizen-owners, including our executive officers, should be targeted near the 50th percentile of actual total cash compensation for individuals in similar positions at comparable companies; for a year in which company performance far exceeds industry standards, the Compensation Committee believes it should be at approximately the 75th percentile of actual total cash compensation. In addition to using survey data from our compensation peer group, the Compensation Committee uses a variety of other factors in evaluating the appropriate level of total cash compensation, including the individual’s level of responsibility, his or her leadership role in achieving our company goals, his or her annual contributions to company performance, and the ability and impact on our company of replacing the individual.

Following completion of the DPI merger, the Compensation Committee evaluated our overall compensation program by reference to the peer group of public companies described above. This analysis revealed that the total cash compensation of our executive officers was substantially below market. Specifically, Mr. Holtzman’s

Table of Contents

scheduled total cash compensation for calendar year 2006 was lower than what each of the 18 chief executive officers in the peer group had received for calendar year 2005. Total scheduled cash compensation for 2006 for Dr. Adams was lower than that received in 2005 by 16 of the 18 senior scientific officers in the peer group, and total scheduled cash compensation for 2006 for Ms. Perkins was lower than that received in 2005 by 17 of the 18 senior business officers in the peer group.

Following this analysis, the Compensation Committee concluded that it was necessary to increase cash compensation to market-competitive levels. However, the committee also believed that raising committed base salaries to levels approaching the median total cash compensation of this peer group would increase inappropriately the company’s fixed cost structure. To address these issues, in December 2006 the Compensation Committee made two decisions:

 

   

raised our executive officers’ base salaries to the following:

 

     2007
Base Salary

Steve H. Holtzman

   $ 450,000

Julian Adams, Ph.D.  

   $ 375,000

Adelene Q. Perkins

   $ 350,000

and

 

   

implemented a contingent cash compensation program for all citizen-owners, including our executive officers.

Under the contingent cash compensation program, the aggregate amount of cash available for award as contingent cash compensation is established by reference to the Compensation Committee’s assessment of company performance. The aggregate amount of cash available for potential award to our executive officers is as follows:

 

     Available Amounts as a Percentage of Base Salary

Exceeds Infinity

Expectations

 

Chief Executive Officer

   0 %   30 %   40 %   50 %

Other Executive Officers

   0 %   25 %   30 %   35 %

Once the aggregate amount available for potential award under our contingent cash compensation program is established (as a function of overall company performance), the Compensation Committee then determines how much of this amount to award to each of our named executive officers based upon a combination of company and individual performance. For Mr. Holtzman, company performance accounts for 90% of the award, while individual performance accounts for 10% of the award. For our other named executive officers, company performance accounts for 80% of the award, while individual performance accounts for 20% of the award. The Compensation Committee believes that our weighting of company and individual performance in this manner is appropriate, since our executive officers have the greatest opportunity, as well as the obligation, to influence company performance.

We believe that our contingent cash compensation program provides the following advantages:

 

   

it is consistent with the growing practice in the biotechnology industry to keep restrained executive base salaries while granting discretionary, performance-based cash bonuses;

 

   

it enables us to achieve our goal of ensuring that total cash compensation is market competitive, thus enhancing our ability to attract and retain the best possible people, without increasing fixed salary expense;

 

   

it rewards the achievement of company goals and strong individual performance in support of those goals, thus maintaining our culture of combining individual excellence and achievement with community collaboration;

 

28


Table of Contents
   

it is consistent with our company’s values, as all citizen-owners are eligible to participate in the program; and

 

   

it further aligns citizen-owner and shareholder interests, as a substantial percentage of our executive officers’ total compensation is dependent on the achievement of company goals.

In January 2007, the Compensation Committee, based on its assessment that the company had convincingly “exceeded Infinity expectations” in 2006 and after reviewing the individual contributions of each of our executive officers, authorized the following contingent cash compensation:

   $ 94,900

Stock Options

Our equity award program is the primary vehicle for offering long-term incentives to all of our citizen-owners, including our executive officers. We believe that equity grants are fundamental in creating a culture of citizen-ownership, providing our citizen-owners with a strong link to our long-term performance and aligning the interests of our citizen-owners and our non-employee stockholders. In addition, the vesting feature of our equity grants should further our goal of retention because it provides an incentive for our citizen-owners, including our executive officers, to remain in our employ during the vesting period.

Our equity awards have generally taken the form of stock options. Stock options granted to new citizen-owners upon their hire typically vest as to one-quarter of the shares on the first anniversary of the date of hire, and monthly over the following 36 months. Subsequent stock options granted under our merit stock option program vest monthly over the first four years of the ten year option term. Vesting and exercise rights cease shortly after termination of employment except in the case of death or disability. Prior to the exercise of an option, the holder has no rights as a stockholder with respect to the shares subject to such option, including no voting rights and no right to receive dividends or dividend equivalents. The exercise price for each stock option share is equal to the closing price of a share of our common stock on the NASDAQ Global Market on the date of grant. While certain rights to grant stock options have been delegated to Mr. Holtzman by and on behalf of the Compensation Committee, all equity-based awards made to our executive officers are approved by the Compensation Committee.

We do not time option grants to our executive officers in coordination with our release of material non-public information. We have not adopted stock ownership guidelines for our executive officers.

In the first quarter of each year, all of our citizen-owners, including our executive officers, are eligible to receive merit stock option grants in connection with the annual performance review process. The aggregate number of shares available for potential award to each of our executive officers under our merit stock option program is based on the Compensation Committee’s assessment of the achievement of company goals for the prior year, and is equal to a percentage of the number of stock options that would be granted to such officers if they were to be newly hired into that position:

For example, if the Compensation Committee concluded that it would be required to grant options to purchase 250,000 shares of our common stock in order to hire a new chief scientific officer, in a year in which we met expectations, Dr. Adams, our current chief scientific officer, would be eligible to receive an option to purchase 25% of 250,000 shares of common stock, or 62,500 shares of our common stock.

In determining the size of annual equity grants to our executive officers, the Compensation Committee considers factors such as share ownership of comparable executive officers in our compensation peer group, our annual company performance, the applicable officer’s individual performance, the amount of equity previously awarded to the officer, and the amount of such equity that remains unvested. The Compensation Committee also evaluates the potential dilution that new stock option grants will have on the ownership interests of our stockholders, as well as the number of shares of our common stock that are available for award under our equity incentive plan.

In January 2007, the Compensation Committee granted to our executive officers options to purchase the following number of shares of our common stock:

 

     Stock Options

Steve H. Holtzman

   250,000

Julian Adams, Ph.D.  

   200,000

Adelene Q. Perkins

   200,000

These grants represent the application of the formula set forth above, following the Compensation Committee’s assessment that the company had convincingly “exceeded Infinity expectations” in 2006, in addition to a one-time adjustment designed to:

 

   

increase the comparative share ownership of our executive officers to levels comparable to those held by executives of companies in our compensation peer group; and

 

   

increase the number of unvested stock options held by each officer, thus enhancing the retention value of the new awards and increasing the percentage of unvested stock options held by Mr. Holtzman, Dr. Adams and Ms. Perkins from 19% to 48%, 46% to 68%, and 31% to 66%, respectively.

Benefits and Other Compensation

We provide a broad-based benefits program for all of our citizen-owners, including health and dental insurance, life and disability insurance, group insurance discounts, first-time homebuyer’s assistance, educational assistance, paid sabbatical leave following five years of service, subsidized parking, and a 401(k) savings plan. Our executive officers are eligible to participate in all of our benefit plans, in each case on the same basis as other citizen-owners. In December 2006, our board of directors authorized a new company-matching feature under our 401(k) savings plan that will be effective beginning in 2007. Under this feature, the company will match 50% of each citizen-owner’s contributions to our 401(k) savings plan with shares of our common stock with a value of up to a maximum of 6% of such citizen-owner’s base salary, subject to applicable IRS limitations.

We have not provided any material perquisites or other personal benefits to our executive officers.

Severance Benefits

We entered into an offer letter with each of our executive officers when they were initially hired by Old Infinity. The letter with Mr. Holtzman provides that if his employment is terminated by us without “cause” or by Mr. Holtzman for “good reason,” as each of those terms is defined in the offer letter, and upon execution by Mr. Holtzman of a severance agreement and release of claims, he will be eligible to receive salary continuation until the first anniversary of the date of his termination or, if earlier, the date on which he begins work with another employer or as a consultant or independent contractor, on either a full-time or part-time basis.

Table of Contents

In addition, the offer letters for Dr. Adams and Ms. Perkins provide that, if his or her employment is terminated by us without “cause,” as that term is defined in the offer letter, or if he or she resigns due to a material diminution in job responsibilities or title or as a result of our failure to fulfill our obligations in the offer letter, and upon execution by such officer of a severance agreement and release of claims, he or she will be eligible to receive a severance payment equal to his or her then-current base salary for a period of six months for Dr. Adams, and 12 months for Ms. Perkins, following the effective date of termination. The offer letters also provide for the continued vesting of each officer’s unvested shares of common stock for a period of six months for Dr. Adams, and 12 months for Ms. Perkins, from the date of termination.

Transactions Associated with the DPI Merger

In contemplation of the merger, the boards of directors of DPI and Old Infinity took certain actions relating to the compensation of the executive officers of DPI and Old Infinity.

Loan Forgiveness

In March 2006, Old Infinity’s board of directors authorized the forgiveness of any outstanding indebtedness that each of our executive officers had to the company, including, in the case of Dr. Adams, certain indebtedness transferred to his former spouse. In connection with such forgiveness, Old Infinity entered into letter agreements with each of these executive officers that provided for each officer to subject certain shares of common stock held by him or her, for a period of two years, to a right of repurchase in the company’s favor.

Change-in-Control Agreements

Between 2003 and 2005, DPI’s board of directors entered into change-in-control agreements with each of its executive officers. The completion of the merger in September 2006 was a triggering event under these agreements. Under the terms of these agreements, each executive officer of DPI became entitled to a severance payment equal to:

 

   

the executive officer’s average annual bonus over the three prior full calendar years of employment with DPI, or such lesser number of full calendar years during which such executive was employed by DPI, multiplied by the number of days in the calendar year through the date of termination divided by 365, plus

 

   

the greater of 100% of:

 

   

the executive officer’s annual base salary in effect immediately prior to the change in control or

 

   

the executive officer’s annual salary in effect at time of the notice of termination.

In addition, for purposes of determining the vesting of each executive officer’s awards granted under DPI’s 2000 Stock Incentive Plan, as well as any unvested shares acquired pursuant to that plan, each of DPI’s executive officers was treated as if he had completed an additional year of service immediately prior to the date on which his employment was terminated.

Approximately $1.9 million was paid to the former executive officers of DPI upon completion of the merger as a result of these agreements. In addition, in connection with the completion of the merger, vesting accelerated as to approximately 6,250 shares of DPI common stock, with exercise prices ranging from $11.80 to $16.80 per share, and 5,750 shares of restricted stock held by DPI’s executive officers.

Retention and Severance Plans

In addition to the change-in-control agreements described above, in March 2006 DPI engaged Alcock & McFadden, a human resources consulting firm, to review DPI’s then-existing compensation arrangements,

 

31


Table of Contents

including DPI’s change-in-control agreements and severance payment practice, in light of the strategic alternatives that were being considered by DPI at that time. These strategic alternatives included the merger and the separate sale of DPI’s operating assets. Alcock & McFadden recommended to DPI’s Compensation Committee, and the committee adopted following a review of market data available for comparable companies, a retention and severance plan. Under this plan, certain employees of DPI, including its executive officers other than Dr. Venuti, became entitled to receive a cash retention bonus of up to $25,000 upon achievement of employee-specific milestones, such as completion of the sale of DPI’s operating assets, completion of the merger, or such other milestones determined by DPI’s Compensation Committee, as long as the employee remained employed with DPI through the earlier of a change in control or December 31, 2006. The plan also provided certain executive officers with severance payments equal to six months of their base salary plus COBRA coverage and three months of outplacement services in the event of a change in control that was not covered under such officer’s existing change-in-control agreement.

Further, in April 2006, DPI approved an executive retention and severance agreement with Dr. Venuti, under which he became entitled to receive a retention bonus of up to $25,000 in cash, with amounts earned upon achievement of specific milestones such as completion of the sale of DPI’s operating assets, completion of the merger, or such other milestones determined by DPI’s Compensation Committee, as long as he remained employed with DPI through the earlier of a change in control or December 31, 2006. The agreement also provided severance payments equal to six months of Dr. Venuti’s base salary plus COBRA coverage, and three months of outplacement services in the event of a change in control that is not covered under Dr. Venuti’s change-in-control agreement.

Approximately $850,000 was paid to DPI’s key employees, including its executive officers, upon completion of the merger pursuant to these retention and severance plans.

In addition, both the plan of March 30, 2006, and the agreement with Dr. Venuti provided for the acceleration in full, upon completion of the merger, of the vesting of restricted stock awards that had previously been granted to certain executive officers and key employees of DPI. The completion of the merger resulted in the accelerated vesting of approximately 110,062 shares of restricted stock for certain of DPI’s executive officers and key employees.

Compensation of DPI’s Executive Officers

DPI’s Compensation Committee set base salaries of each of its executive officers on the basis of:

 

   

industry experience, knowledge and qualifications,

 

   

salary levels in effect for comparable positions within DPI’s principal-industry marketplace competitors, and

 

   

internal comparability.

DPI’s Compensation Committee aimed to set base salaries in a range from the 50th percentile to the 75th percentile of the salary levels in effect for comparable positions at those other companies. In March 2006, DPI increased the base salaries of its executive officers by the following percentages:

 

     Percentage Increase  

Michael C. Venuti, Ph.D.  

   4 %

Craig Kussman

   4 %

Douglas A. Livingston, Ph.D.  

   2.19 %

Richard C. Neale

   4 %

Table of Contents

No discretionary cash bonuses were paid to DPI’s executive officers in connection with their 2006 performance.

In March 2006, DPI’s Compensation Committee made an award of 6,250 shares of restricted stock to Mr. Neale in order to balance equity ownership among employees. No other equity-based awards were granted to DPI’s executive officers during 2006.

Accounting and Tax Considerations

Beginning on January 1, 2006, we began accounting for stock-based payments in accordance with the requirements of Financial Accounting Standards Board Statement No. 123(R), “Share-Based Payment,” or FAS 123R. To date, the adoption of FAS 123R has not impacted our stock option granting practices.

Section 162(m) of the Internal Revenue Code of 1986, as amended, generally disallows a tax deduction for compensation in excess of $1,000,000 paid to our executive officers. Qualifying performance-based compensation is not subject to the deduction limitation if specified requirements are met. At this time, we do not have a policy to factor Section 162(m) limitations into the determination of base salary or contingent cash compensation amounts, since the aggregate payments for each individual are substantially below the $1,000,000 deductibility limitation.

The primary elements of our compensation program, with respect to our named executive officers, are:

 

   

base salary and contingent cash compensation;

 

   

annual merit stock option awards;

 

   

employee benefits, such as insurance and a 401(k) savings plan; and

 

   

severance benefits.

The amounts of contingent cash compensation and the size of annual merit stock option awards differ from person to person based on such person’s role and tenure in that role, market-competitive compensation, and his or her individual performance.

We do not have any formal or informal policy or target for allocating compensation between cash and non-cash compensation or among the different forms of non-cash compensation. Instead, the Compensation Committee, after reviewing relevant information, determines subjectively what it believes to be the appropriate level and mix of the various compensation components.

For a more detailed discussion of the compensation paid to our named executive officers, see above under the heading “Compensation Discussion and Analysis—Components of our Compensation Program.”

In addition to the cash compensation discussed above, non-employee directors are eligible to receive non-statutory stock options, restricted stock and other stock-based awards for our common stock under our 2000 Stock Incentive Plan as follows:

 

   

Each non-employee director who served on the board of directors immediately after the closing of the merger and each new director, on the date of his or her election to the board of directors, will receive a non-statutory stock option to purchase 28,125 shares of our common stock which will vest as to 9,375 of the shares on the first anniversary of the grant date and the remainder in quarterly installments of 2,343 shares beginning at the end of the first quarter thereafter, provided that the holder continues to serve as a director.

Each automatic grant will have an exercise price per share equal to the fair market value per share of our common stock on the grant date and will have a term of 10 years, subject to earlier termination following the optionee’s cessation of board service.

Our board of directors has approved an amendment to our 2000 Stock Incentive Plan, which amendment is subject to, and will become effective upon, the filing of the restated certificate of incorporation with the Secretary of State of the State of Delaware if Proposal 2 is approved by stockholders at the 2007 annual meeting of stockholders. The amendment provides for the following grants of non-statutory stock options to our non-employee directors:

 

   

Each non-employee director initially elected to the board following September 12, 2006, on the date of his or her initial election to the board, will receive a non-statutory option to purchase 9,375 shares of our common stock. Shares subject to each such option will become exercisable in equal quarterly installments beginning at the end of the first quarter after the date of grant, provided that the holder of the option continues to serve as a director.

 

   

Each non-employee director shall, on the date of the first annual stockholders meeting following the first anniversary of his or her initial election to the board and on the date of each annual stockholders meeting thereafter, receive a non-statutory option to purchase 5,625 shares of common stock; provided, however, that such options will not be granted to non-employee directors serving on the board on September 13, 2006 until the first annual stockholders meeting after September 12, 2009. Shares of common stock subject to each such option will be exercisable in equal quarterly installments beginning at the end of the first quarter after the date of grant, provided that the holder of the option continues to serve as a director.

The amendment will not change the additional grants of non-statutory stock options made to our lead outside director, lead research and development director, chair of our Audit Committee, chair of our Compensation Committee and chair of Corporate Governance Committee, for service in such positions, as described above.

Compensation Committee Interlocks and Insider Participation

The current members of the Compensation Committee are Drs. Evnin and Moss and Mr. Lee. Other than Dr. Moss, who was an employee of Old Infinity in 2003, no member of the Compensation Committee was at any time during 2006, or formerly, an officer or employee of ours or any subsidiary of ours, nor has any member of the Compensation Committee had any relationship with us requiring disclosure under Item 404 of Regulation S-K under the Exchange Act.

No executive officer of Infinity has served as a director or member of the Compensation Committee (or other committee serving an equivalent function) of any other entity, one of whose executive officers served as a director of or member of our Compensation Committee.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with our management. Based on this review and discussion, the Compensation Committee recommended to our board of directors that the Compensation Discussion and Analysis be included in this proxy statement.

PROPOSAL 2—AMENDMENT AND RESTATEMENT

OF THE CERTIFICATE OF INCORPORATION

General Information

Article VI of our certificate of incorporation, as amended, provides that our board of directors be divided into three classes, as nearly equal in number as possible, with members of each class serving three-year terms. In addition, Article VI also provides that, generally, directors can be removed from our board of directors only for cause by the holders of at least sixty-six and two-thirds percent of our common stock. This system for electing and removing directors was adopted prior to our becoming a publicly traded company in 2000.

Our board of directors has unanimously adopted resolutions, subject to stockholder approval, approving and declaring the advisability of amending and restating our certificate of incorporation to declassify the board of directors such that directors shall be elected annually and to allow the holders of a majority the outstanding shares of our common stock to remove a director with or without cause. As described below under Proposal 3 – Amendment of the By-laws, our board of directors has also approved an amendment to our by-laws that, if approved by our stockholders, would make our by-laws consistent with the amendment and restatement of the certificate of incorporation.

If our stockholders approve the proposed amendment and restatement of our certificate of incorporation and the amendment to our by-laws, the terms for all of our directors would end at our 2008 annual meeting. Accordingly, beginning with the 2008 annual meeting, all directors would be elected for one-year terms at each annual meeting and the holders of a majority of the outstanding shares of our common stock would be entitled to remove directors with or without cause. If these proposals are adopted, any director appointed by the board as a result of the newly created directorship or to fill a vacancy on the board of directors would hold office until the next annual meeting.

If the proposal to amend and restate our certificate of incorporation is not approved, our board of directors will remain classified and the directors elected at the 2007 annual meeting of stockholders will serve three-year terms expiring in 2010. All other directors will remain in office for the remainder of their three-year terms.

Background of Proposal

Classified or staggered boards have been widely adopted and have a long history in corporate law. Proponents of classified boards assert they promote the independence of directors because directors elected for multi-year terms are less subject to outside influence. Proponents of a staggered system for the election of directors also believe it provides continuity and stability in the management of the business and affairs of a company because a majority of directors always have prior experience as directors of the company. This continuity and long-term focus is particularly important to research-based organizations, such as ours, where product and technology development is complex and long-term. Proponents further assert that classified boards may enhance stockholder value by forcing an entity seeking control of a target company to initiate arms-length discussions with the board of a target company because the entity is unable to replace the entire board in a single election.

On the other hand, some investors view classified boards as having the effect of reducing the accountability of directors to stockholders because classified boards limit the ability of stockholders to evaluate and elect all directors on an annual basis. The election of directors is a primary means for stockholders to influence corporate governance policies and to hold management accountable for implementing those policies. In addition, opponents of classified boards assert that a staggered structure for the election of directors may discourage proxy contests in which stockholders have an opportunity to vote for a competing slate of nominees and therefore, may erode stockholder value.

The Corporate Governance Committee has recommended to our board of directors that we declassify our board of directors. Our full board of directors has considered carefully the advantages and disadvantages of maintaining a classified board structure. After this assessment, the full board of directors, upon the recommendation of our Corporate Governance Committee, has decided that this is an appropriate time to propose declassifying the board. This determination by the board furthers its goal of ensuring that our corporate governance policies maximize management accountability to stockholders and would, if adopted, allow stockholders the opportunity each year to register their views on the performance of the board of directors.

Under Delaware corporate law, stockholders may be limited to removing directors only for cause, but only if the company has a classified board. For Delaware corporations without a classified board, the holders of a majority of the outstanding shares of voting stock are entitled to remove directors with or without cause. Accordingly, we are also proposing to eliminate a provision in Article VI of our certificate of incorporation, as amended, that allows stockholders to remove directors only for cause in conjunction with our proposal to declassify our board. Under Delaware law, directors cannot be removed by other directors, and the proposed amendment will not change this.

Restated Certificate of Incorporation

The proposed amendment and restatement of our certificate of incorporation is set forth in Appendix A, and we have shown the changes to the relevant sections resulting from the amendment and restatement, with deletions indicated by strike-outs and additions indicated by underlining. In addition to the changes that pertain specifically to the declassification of our board, Appendix A also reflects certain changes that we are required to make as a result of amending and restating our certificate of incorporation, specifically changes to incorporate prior amendments of our certificate of incorporation and a previously-filed certificate of designation of Series A Junior Participating Preferred Stock. If approved, this proposal will become effective upon the filing of the restated certificate of incorporation with the Secretary of State of the State of Delaware, which we intend to do promptly after approval of this proposal at the annual meeting in the event that Proposal 3 – Amendment of the By-laws is also approved.

Our board of directors recommends a vote “FOR” the proposal to adopt the restated certificate of incorporation.

PROPOSAL 3—AMENDMENT AND RESTATEMENT OF THE BY-LAWS

General Information

Article III, Section 1 of our by-laws, as amended, provides that our board of directors be divided into three classes, as nearly equal in number as possible, with members of each class serving three-year terms. In addition, Article III, Section 13 provides that directors can be removed from the board of directors only for cause by the holders of at least two-thirds of the outstanding shares of our common stock. Finally, Article X, Sections 1(b) and (c) provide that the provisions of Article III, Sections 1 and 13 can be amended, repealed or altered only upon the affirmative vote of holders of 66 2/3% of the outstanding shares of our common stock and by 66 2/3% of our directors.

Our board of directors has unanimously adopted resolutions, subject to stockholder approval, approving and declaring the advisability of amending our by-laws to declassify the board of directors such that directors shall be elected annually and to allow the holders of a majority of the outstanding shares of our common stock to remove a director with or without cause. Such amendment will also eliminate the super-majority stockholder and director voting requirements that related to altering these provisions in connection with the elimination of such provisions. As described above under Proposal 2 – Amendment and Restatement of the Certificate of Incorporation, the board of directors has also approved amending and restating our certificate of incorporation that, if approved by our stockholders, would make the certificate of incorporation consistent with the amendment of the by-laws. If the proposed amendment of our by-laws and amendment and restatement of our certificate of incorporation are approved by our stockholders, the terms for all of our directors would end at our 2008 annual meeting. Accordingly, beginning with the 2008 annual meeting, all directors would be elected for one-year terms at each annual meeting and the holders of a majority of the outstanding shares of our common stock would be entitled to remove directors with or without cause. If this proposal is adopted, any director appointed by the board as a result of the newly created directorship or to fill a vacancy on the board of directors would hold office until the next annual meeting.

If the proposal to amend our by-laws is not approved, our board of directors will remain classified and the directors elected at the 2007 annual meeting of stockholders will serve three-year terms expiring in 2010. All other directors will remain in office for the remainder of their three-year terms.

The board of directors has set the current number of directors at 12. The proposal would not change the present number of directors and the directors will retain the authority to change that number and to fill any vacancies or newly created directorships.

Background of Proposal

For a discussion of the factors that our independent directors and our board of directors considered in determining to declassify our board, please refer to the discussion under “Proposal 2 – Amendment and Restatement of the Certificate of Incorporation—Background of Proposal.”

Amendment to By-laws

The proposed amendment of our by-laws is set forth in Appendix B, and we have shown the changes to the relevant sections resulting from the amendment, with deletions indicated by strike-outs and additions indicated by underlining. If this proposal and Proposal 2 are both approved, this proposal will become effective upon the filing of the restated certificate of incorporation with the Secretary of State of the State of Delaware, which we intend to do promptly after approval of this proposal at the annual meeting. This proposal will only become effective if Proposal 2 is approved.

Our board of directors recommends a vote “FOR” the proposal to adopt the amendment to our by-laws to declassify the board of directors, to allow for the removal of directors without cause and to effect certain other matters.

PROPOSAL 4—RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has selected the firm of Ernst & Young LLP as our independent registered public accounting firm for the current fiscal year. Ernst & Young LLP has served as the independent registered public accounting firm of Old Infinity since 2001. Although stockholder approval of the selection of Ernst & Young LLP is not required by law, the board of directors believes that it is advisable to give stockholders an opportunity to ratify this selection. If this proposal is not approved at our 2007 annual meeting, our Audit Committee will reconsider its selection of Ernst & Young LLP. Representatives of Ernst & Young LLP are expected to be present at the annual meeting and will have the opportunity to make a statement if they desire to do so and will also be available to respond to appropriate questions from stockholders.

Board Recommendation

The board of directors believes that the selection of Ernst & Young LLP as our independent registered public accounting firm is in our best interests and the best interests of our stockholders and therefore recommends a vote FOR this proposal.

OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and holders of more than 10% of our common stock to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other of our equity securities. Based solely on our review of copies of Section 16(a) reports furnished to us and representations made to us, we believe that during Fiscal 2006, our officers, directors and holders of more than 10% of our common stock complied with all Section 16(a) filing requirements.

Stockholder Proposals for the 2008 Annual Meeting

We must receive proposals of stockholders intended to be presented at the 2008 annual meeting of stockholders at our principal executive offices, c/o Gerald E.

In addition, our by-laws require that we be given advance notice of stockholder nominations for election to our board of directors and of other matters which stockholders wish to present for action at an annual meeting of stockholders (other than matters included in our proxy statement in accordance with Rule 14a-8 of the Exchange Act). The required notice must be received by our Vice President and General Counsel, Gerald E. Quirk, at our principal executive offices not later than January 31, 2008. However, if the date of our 2008 annual meeting is prior to February 29, 2008 or after August 28, 2008, the notice must be received no earlier than the 120th day prior to the 2008 annual meeting and no later than the close of business on the later of (1) the 60th day prior to the 2008 annual meeting and (2) the 10th day following the date on which notice of the date of the annual meeting was mailed or publicly disclosed, whichever occurs first. If the stockholder fails to provide timely notice of a proposal to be presented at the 2008 annual meeting, the chairman of the meeting may exclude the proposal from being brought before the meeting and the proxies designated by our board of directors will have discretionary authority to vote on such proposal should it be allowed to come before the meeting.

Pursuant to Section 242 of the General Corporation Law of the State of Delaware, Discovery Partners International, Inc., a corporation organized and existing under the laws of the State of Delaware (the “Corporation”), does hereby certify as follows:

The name of the Corporation is Discovery Partners International, Inc. and the Corporation’s original Certificate of Incorporation was filed with the Secretary of State of the State of Delaware on May 11, 2000. The Board of Directors of the Corporation has duly adopted a resolution pursuant to Section 242 of the General Corporation Law of the State of Delaware setting forth a proposed amendment to the Certificate of Incorporation of the Corporation and declaring said amendment to be advisable. The requisite stockholders of the Corporation have duly approved said proposed amendment in accordance with Section 242 of the General Corporation Law of the State of Delaware. The amendment amends the Certificate of Incorporation of the Corporation as follows:

“Effective upon the filing of this Certificate of Amendment of Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Effective Time”), the shares of Common Stock issued and outstanding immediately prior to the Effective Time and the shares of Common Stock issued and held in the treasury of the Corporation immediately prior to the Effective Time are reclassified into a smaller number of shares such that each two to six shares of issued Common Stock immediately prior to the Effective Time is reclassified into one share of Common Stock, the exact ratio within the two-to-six range to be determined by the board of directors of the Corporation prior to the Effective Time and publicly announced by the Corporation. Notwithstanding the immediately preceding sentence, no fractional shares shall be issued and, in lieu thereof, upon surrender after the Effective Time of a certificate which formerly represented shares of Common Stock that were issued and outstanding immediately prior to the Effective Time, any person who would otherwise be entitled to a fractional share of Common Stock as a result of the reclassification, following the Effective Time, shall be entitled to receive a cash payment equal to the fraction to which such holder would otherwise be entitled multiplied by the closing price of a share of Common Stock on the NASDAQ Global Market immediately following the Effective Time.

Each stock certificate that, immediately prior to the Effective Time, represented shares of Common Stock that were issued and outstanding immediately prior to the Effective Time shall, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of Common Stock after the Effective Time into which the shares of Common Stock formerly represented by such certificate shall have been reclassified (as well as the right to receive cash in lieu of fractional shares of Common Stock after the Effective Time), provided, however, that each person of record holding a certificate that represented shares of Common Stock that were issued and outstanding immediately prior to the Effective Time shall receive, upon surrender of such certificate, a new certificate evidencing and representing the number of whole shares of Common Stock after the Effective Time into which the shares of Common Stock formerly represented by such certificate shall have been reclassified.” IN WITNESS WHEREOF, the Corporation has caused this Certificate of Amendment to be signed by its

OF

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

OF

DISCOVERY PARTNERS INTERNATIONAL, INC.,

FEBRUARY 13, 2003

(PURSUANT TO SECTION 151 OF THE

DELAWARE GENERAL CORPORATION LAW)

 


Discovery Partners International, Inc., a corporation organized and existing under the General Corporation Law of the State of Delaware (hereinafter called the “Corporation”), hereby certifies that the following resolution was adopted by the board of directors of the Corporation as required by Section 151 of the General Corporation Law at a meeting duly called and held on February 13, 2003;

RESOLVED, that pursuant to the authority granted to and vested in the board of directors of the Corporation (hereinafter the “Board”) in accordance with the provisions of the certificate of incorporation of the Corporation, as currently in effect, the Board hereby creates a series of Preferred Stock, par value $0.001 per share (the “Preferred Stock”), of the Corporation and hereby states the designation and number of shares, and fixes the relative rights, preferences, and limitations thereof as follows:

Series A Junior Participating Preferred Stock:

Section 1. Designation and Amount. The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” (the “Series A Preferred Stock”) and the number of shares constituting the Series A Preferred Stock shall be ninety nine thousand (99,000). Such number of shares may be increased or decreased by resolution of the Board of Directors; provided, that no decrease shall reduce the number of shares of Series A Preferred Stock to a number less than the number of shares then outstanding plus the number of shares reserved for issuance upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities issued by the Corporation convertible into Series A Preferred Stock.

Section 2. Dividends and Distributions.

(a) Subject to the rights of the holders of any shares of any series of Preferred Stock (or any similar stock) ranking prior and superior to the Series A Preferred Stock with respect to dividends, each holder of a share of Series A Preferred Stock, in preference to the holders of shares of common stock, par value $0.001 per share (the “Common Stock”), of the Corporation, and of any other junior stock, shall be entitled to receive, when declared by the Board out of funds legally available for the purpose, dividends in an amount per share (rounded to the nearest cent) equal to, subject to the provision for adjustment hereinafter set forth, 1,000 times the aggregate per share amount of all cash dividends, and 1,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions, other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock. In the event the Corporation shall, at any time after February 13, 2003 (the “Rights Declaration Date”), declare or pay any dividend on the Common Stock

payable in shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock (and an equivalent dividend is not declared on the Series A Preferred Stock or the Series A Preferred Stock is not similarly subdivided or combined), then in each such case the amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under the preceding sentence shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(b) The Corporation shall declare a dividend or distribution on the shares of Series A Preferred Stock as provided in Section 2(a) immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided, however, that, in no event shall a dividend or distribution be declared by the Board on the Common Stock for which it does not declare and pay the dividend required to be declared on the Preferred Stock pursuant to Section 2(a).

(c) Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board may fix a record date for the determination of holders of shares of Series A Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be not more than sixty days prior to the date fixed for the payment thereof.

Section 3. Voting Rights. The holders of shares of Series A Preferred Stock shall have the following voting rights:

(a) Subject to the provision for adjustment hereinafter set forth, each share of Series A Preferred Stock shall entitle the holder thereof to 1,000 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall, at any time after the Rights Declaration Date, declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock (and an equivalent dividend is not declared on the Series A Preferred Stock or the Series A Preferred Stock is not similarly subdivided or combined), then in each such case the number of votes per share to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(b) Except as otherwise provided herein, in the Certificate of Incorporation, in any other Certificate of Designation creating a series of Preferred Stock or any similar stock, or by law, the holders of shares of Series A Preferred Stock and the holders of shares of Common Stock and any other capital stock of the Corporation having general voting rights shall vote together as one class on all matters submitted to a vote of stockholders of the Corporation.

(c) Except as set forth herein, or as otherwise provided by law, holders of Series A Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action.

Section 4. Certain Restrictions.

(a) Whenever quarterly dividends or other dividends or distributions payable on the Series A Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and

distributions, whether or not declared, on shares of Series A Preferred Stock outstanding shall have been paid in full, the Corporation shall not:

(i) declare or pay dividends, or make any other distributions, on any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock;

(ii) declare or pay dividends, or make any other distributions, on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except dividends paid ratably on the shares of Series A Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled;

(iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock; provided, that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such junior stock in exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series A Preferred Stock; or

(iv) redeem or purchase or otherwise acquire for consideration any shares of Series A Preferred Stock, or any shares of stock ranking on a parity with the Series A Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board) to all holders of such shares upon such terms as the Board, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(b) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under Section 4(a), purchase or otherwise acquire such shares at such time and in such manner.

Section 5. Reacquired Shares. Any shares of Series A Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock subject to the conditions and restrictions on issuance set forth herein, in the certificate of incorporation, or in any other certificate of designation creating a series of Preferred Stock or any similar stock or as otherwise required by law.

Section 6. Liquidation, Dissolution or Winding Up.

(a) Upon any liquidation, dissolution or winding up of the Corporation, no distribution shall be made (i) to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Stock unless, prior thereto, the holders of shares of Series A Preferred Stock shall have received the greater of (x) $1,000 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon to the date of such payment (the “Series A Liquidation Preference”) and (y) an aggregate amount per share, subject to the provision for adjustment hereinafter set forth, equal to the product of 1,000 times the aggregate amount to be distributed per share to holders of shares of Common Stock, or (ii) to the holders of shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Preferred Stock, except distributions made ratably on the Series A Preferred Stock and all such parity stock in proportion to the total amounts to which the holders of all such shares are entitled upon such liquidation, dissolution or winding up. In the event the Corporation shall, at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock (and an equivalent dividend is not declared on the Series A Preferred Stock or the Series A Preferred Stock is not similarly subdivided or

combined), then in each such case the aggregate amount to which holders of shares of Series A Preferred Stock were entitled immediately prior to such event under the proviso in clause (i) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(b) In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of Preferred Stock, if any, which rank on a parity with the Series A Preferred Stock, then such remaining assets shall be distributed ratably to the holders of Series A Preferred Stock and such parity shares in proportion to their respective liquidation preferences.

Section 7. Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or converted or changed into other stock or securities, cash and/or any other property (or into the right to receive any of the foregoing), then in any such case each share of Series A Preferred Stock shall at the same time be similarly exchanged, converted or changed into an amount per share, subject to the provision for adjustment hereinafter set forth, equal to 1,000 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is converted, changed or exchanged. In the event the Corporation shall, at any time after the Rights Declaration Date declare or pay any dividend on the Common Stock payable in shares of Common Stock, or effect a subdivision or combination or consolidation of the outstanding shares of Common Stock (by reclassification or otherwise than by payment of a dividend in shares of Common Stock) into a greater or lesser number of shares of Common Stock (and an equivalent dividend is not declared on the Series A Preferred Stock or the Series A Preferred Stock is not similarly subdivided or combined), then in each such case the amount set forth in the preceding sentence with respect to the conversion, exchange or change of shares of Series A Preferred Stock shall be adjusted by multiplying such amount by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event.

Section 8. No Redemption. The shares of Series A Preferred Stock shall not be redeemable.

Section 9. Rank. The Series A Preferred Stock shall rank, with respect to the payment of dividends and the distribution of assets, junior to all series of any other class of the Corporation’s Preferred Stock.

Section 10. Amendment. The certificate of incorporation of the Corporation shall not be amended, including any amendment through consolidation, merger, combination or other transaction, in any manner which would materially alter or change the powers, preferences or special rights of the Series A Preferred Stock so as to affect them adversely without the affirmative vote of the holders of at least a majority of the outstanding shares of Series A Preferred Stock, voting together as a single class.

IN WITNESS WHEREOF, this Certificate of Designation is executed on behalf of the Corporation as of the date first written above.
