The Annual Meeting will be held at the Company's offices, located at 6166 Nancy Ridge Drive, San Diego, California 92121. This Proxy Statement, together with the Notice of Annual Meeting of Stockholders, the form of Proxy and the Company's Annual Report to Stockholders, are being mailed on or about March 29, 2001 to all stockholders of record at the close of business on March 15, 2001 (the "Record Date"). RECORD DATE, OUTSTANDING SHARES AND VOTING Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting and any adjournment or postponement thereof. At the close of business on the Record Date, 22,696,913 shares of the Company's common stock were outstanding. Each holder of record of common stock on such date will be entitled to one vote, for each share held, on all matters to be voted on at the Annual Meeting. Cumulative voting is not permitted with respect to any proposal to be acted upon at the Annual Meeting. Stockholders may vote in person or by proxy. All votes will be tabulated by the inspector of election appointed for the Annual Meeting who will separately tabulate affirmative and negative votes, abstentions and broker non-votes. The presence, in person or by proxy, of the holders of a majority of outstanding shares of common stock entitled to vote at the Annual Meeting is necessary to constitute a quorum. Votes withheld from any nominee for election as director, abstentions and broker "non-votes" will be counted as present for purposes of determining the presence or absence of a quorum for the transaction of business. A "non-vote" occurs when a nominee holding shares for a beneficial owner votes on one proposal, but does not vote on another proposal because, in respect of such other proposal, the nominee does not have discretionary voting power and has not received instructions from the beneficial owner. Abstentions will be included in the number of shares present and voting on each matter but will have the effect of a negative vote. Non-votes will not be included in the number of shares present and voting on each matter and will have the effect of reducing the number of affirmative votes required to achieve a majority for such matter by reducing the total number of votes from which a majority is calculated. The election of directors by the stockholders will be determined by a plurality of votes cast by stockholders entitled to vote, and votes withheld will not be counted toward the achievement of a plurality. On all other matters being submitted to the stockholders, the affirmative vote of a majority of the shares, present in person or represented by proxy at the meeting and entitled to vote, will be required for approval. 1 Any proxy which is returned using the form of Proxy enclosed and is not marked as to a particular item will be voted for the election of directors named in the Proxy, for the confirmation of the selection of the designated independent auditors, for the approval of the 2001 Arena Employee Stock Purchase Plan with 1,000,000 shares of common stock reserved for issuance thereunder and, as the proxy holders deem advisable, on other matters that may come before the meeting, as the case may be. In the event that any nominee for director should be unavailable for election as a result of an unexpected occurrence, such shares will be voted for the election of such substitute nominee as designated by the present Board of Directors. REVOCABILITY OF PROXIES Any person giving a Proxy pursuant to this solicitation has the power to revoke it at any time before it is voted. It may be revoked by filing, with the Secretary of the Company at 6166 Nancy Ridge Drive, San Diego, California 92121, a written notice of revocation or a duly executed proxy bearing a later date, or by attending the Annual Meeting and voting in person. COST OF SOLICITATION The cost of soliciting proxies will be borne by the Company. In addition, the Company expects to reimburse brokerage firms and other persons representing beneficial owners of common stock for their expenses in forwarding solicitation material to such beneficial owners. The original solicitation of proxies by mail may be supplemented by solicitation by certain of the Company's directors, officers and regular employees, without additional compensation, in person or by mail, telephone, facsimile, e-mail or telegram. PROPOSAL 1 ELECTION OF DIRECTORS The persons named below are nominees for director to serve until the next annual meeting of stockholders and until their successors have been elected and qualified or until their early resignation or removal. The Company's bylaws provide that the authorized number of directors shall be determined by a resolution of the Board of Directors. The authorized number of directors is currently six. Each nominee listed below is currently a director of the Company. Directors are elected by a plurality of votes present in person or by proxy and entitled to vote at the Annual Meeting. Unless otherwise instructed, the proxy holders will vote the Proxies received by them for the nominees named below. In the event that any nominee of the Company is unavailable to serve as a director at the time of the Annual Meeting, the Proxies will be voted for any substitute nominee who shall be designated by the present Board of Directors.

The affirmative vote of the holders of a majority of shares represented and voting at the meeting will be required to ratify the selection of Ernst & Young LLP. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE RATIFICATION OF THE SELECTION OF ERNST & YOUNG LLP TO SERVE AS THE COMPANY'S INDEPENDENT AUDITORS FOR THE YEAR ENDING DECEMBER 31, 2001. PROPOSAL 3 APPROVAL OF THE 2001 ARENA EMPLOYEE STOCK PURCHASE PLAN This proposal is to approve a new employee stock purchase plan for the Company and the reservation of 1,000,000 shares of common stock for issuance thereunder. On March 15, 2001, the Board of Directors determined that it was in the Company's best interest and in the best interest of the Company's stockholders to adopt the 2001 Arena Employee Stock Purchase Plan (the "Employee Plan") which is described below and attached to this Proxy Statement as Exhibit B. At this time, the Board of Directors has adopted the Employee Plan and reserved common stock for issuance thereunder, subject to stockholder approval, in the amount of 1,000,000 shares. PARTICIPATION IN THE EMPLOYEE PLAN Participation in the Employee Plan is voluntary and is dependent on each eligible employee's election to participate and his or her determination as to the level of payroll deductions. Accordingly, future purchases under the Employee Plan are not determinable. Nonemployee directors are not eligible to participate in the Employee Plan. The essential terms of the Employee Plan are summarized as follows: DESCRIPTION OF THE EMPLOYEE PLAN GENERAL. The purpose of the Employee Plan is to provide employees with an opportunity to purchase common stock of the Company through accumulated payroll deductions. ADMINISTRATION. The Employee Plan may be administered by the Board of Directors or a committee appointed by the Board of Directors. All questions of interpretation or application of the Employee Plan are determined by the Board of Directors or its appointed committee, and its decisions are final, conclusive and binding upon all participants. ELIGIBILITY. Each employee of the Company or its subsidiaries (including officers) whose customary employment with the Company is at least 20 hours per week is eligible to participate in an Offering Period 5 (as defined below); provided, however, that no employee shall be granted an option under the Employee Plan (i) to the extent that, immediately after the grant, such employee would own capital stock and/or hold outstanding options to purchase such stock representing five percent or more of the voting power or value of the stock of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans of the Company accrue at a rate which exceeds $25,000 worth of stock (determined at the fair market value of the shares at the time such option is granted) for each calendar year. Eligible employees become participants in the Employee Plan by filing with the Company a subscription agreement authorizing payroll deductions prior to the beginning of each Offering Period unless a later time for filing the subscription agreement has been set by the Board. As of March 1, 2001, approximately 122 employees, including ten executive officers, were eligible to participate in the Employee Plan. PARTICIPATION IN AN OFFERING. The Employee Plan is implemented by consecutive overlapping offering periods lasting for 24 months (an "Offering Period"), with a new Offering Period commencing on the first trading day on or after January 1, April 1, July 1 and October 1 of each year. Common stock may be purchased under the Employee Plan every three months (a "Purchase Period"), unless the participant withdraws or terminates employment earlier. To the extent the fair market value of the common stock on any exercise date in an Offering Period is lower than the fair market value of the common stock on the first day of the Offering Period, then all participants in such Offering Period will be automatically withdrawn from such Offering Period immediately after the exercise of their options on such exercise date and automatically re-enrolled in the immediately following Offering Period as of the first day thereof. The Board of Directors may change the duration of the Purchase Periods or the length or date of commencement of an Offering Period. To participate in the Employee Plan, each eligible employee must authorize payroll deductions pursuant to the Employee Plan. Such payroll deductions may not exceed 15% of a participant's compensation. Once an employee becomes a participant in the Employee Plan, the employee will automatically participate in each successive Offering Period until such time as the employee withdraws from the Employee Plan or the employee's employment with the Company terminates. At the beginning of each Offering Period, each participant is automatically granted an option to purchase shares of common stock. The option expires at the end of the Offering Period or upon termination of employment, whichever is earlier, but is exercised at the end of each Purchase Period to the extent of the payroll deductions accumulated during such Purchase Period. The number of shares subject to the option may not exceed 625 shares of the common stock in each Purchase Period. PURCHASE PRICE, SHARES PURCHASED. Shares of common stock may be purchased under the Employee Plan at a price not less than 85% of the lesser of the fair market value of the common stock on the (i) the first trading day of each Offering Period or (ii) the last trading day of each Purchase Period. The "fair market value" of the common stock on any relevant date will generally be the closing price per share as quoted on The Nasdaq National Market (or the closing bid, if no sales were reported) as reported in The Wall Street Journal. The number of shares of common stock a participant purchases in each Purchase Period is determined by dividing the total amount of payroll deductions withheld from the participant's compensation during that Purchase Period by the Purchase Price. On March 1, 2001, the closing price per share as reported on the Nasdaq National Market was $23.00. TERMINATION OF EMPLOYMENT. Termination of a participant's employment for any reason, including disability or death, or the failure of the participant to remain in the continuous scheduled employ of the Company for at least 20 hours per week, cancels his or her option and participation in the Employee Plan immediately. In such event, the payroll deductions credited to the participant's account will be returned to him or her or, in the case of death, to the person or persons entitled thereto as provided in the Employee Plan. 6 ADJUSTMENT UPON CHANGE IN CAPITALIZATION. In the event that the Company's common stock is changed by reason of any stock split, reverse stock split, stock dividend, combination, reclassification or other change in the capital structure of the Company affected without the receipt of consideration, appropriate proportional adjustments shall be made in the number and class of shares of stock subject to the Employee Plan, the number and class of shares of stock subject to options outstanding under the Employee Plan and the exercise price of any such outstanding options. Any such adjustment shall be made by the Board of Directors, whose determination shall be conclusive. DISSOLUTION OR LIQUIDATION. In the event of a proposed dissolution or liquidation, the Offering Period then in progress will be shortened and a new exercise date will be set. MERGER OR ASSET SALE. In the event of a merger of the Company with or into another corporation or a sale of all or substantially all of the Company's assets, each outstanding option may be assumed or substituted by the successor corporation. If the successor corporation refuses to assume or substitute the outstanding options, the Offering Period then in progress will be shortened and a new exercise date will be set. AMENDMENT AND TERMINATION OF THE PLAN. The Board of Directors may at any time terminate or amend the Employee Plan. An Offering Period may be terminated by the Board of Directors at the end of any Purchase Period if the Board determines that termination of the Employee Plan is in the best interests of the Company and its stockholders. No amendment shall be effective unless it is approved by the holders of a majority of the votes cast at a duly held stockholders' meeting, if such amendment would require stockholder approval in order to comply with Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). The Employee Plan will terminate in March 2011. WITHDRAWAL. Generally, a participant may withdraw from an Offering Period at any time without affecting his or her eligibility to participate in future Offering Periods. However, once a participant withdraws from a particular offering, that participant may not participate again in the same offering. FEDERAL TAX INFORMATION FOR THE EMPLOYEE PLAN The Employee Plan, and the right of participants to make purchases thereunder, is intended to qualify under the provisions of Sections 421 and 423 of the Code. Under these provisions, no income will be taxable to a participant until the shares purchased under the Employee Plan are sold or otherwise disposed of. Upon sale or other disposition of the shares, the participant will generally be subject to tax and the amount of the tax will depend upon the holding period. If the shares sold or disposed of have been held more than one year from the date of transfer of the stock to the participant or more than two years from the first day of the Offering Period, then the participant will recognize ordinary income on the lesser of (i) 15% of the value of the shares as of the first day of the Offering Period, or (ii) the excess of the value of the shares at the time of such sale or disposition over the Employee Price. Any additional gain will be treated as long-term capital gain. If the shares are sold or disposed of have not been held for the respective one or two year required holding periods, then the participant will recognize ordinary income generally measured as the excess of the value of the shares on the date the shares are purchased over the Employee Price. Any additional gain or loss on such sale or disposition will be long-term or short-term capital gain or loss, depending on the holding period. The Company is not entitled to a deduction for amounts taxed to a participant except to the extent ordinary income is recognized by participants upon a sale or disposition of shares prior to the expiration of the holding periods described above. The foregoing is only a summary of the effect of federal income taxation upon the participant and the Company with respect to the shares purchased under the Employee Plan. In addition, this summary does not discuss the tax consequences of a participant's death or the income tax laws of any state or foreign 7 country in which the participant may reside. Reference should be made to the applicable provisions of the Code for more complete details. The affirmative vote of the holders of a majority of shares represented and voting at the meeting will be required to approve the Employee Plan. THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE "FOR" THE APPROVAL OF THE EMPLOYEE PLAN DESCRIBED ABOVE, AND RESERVATION OF 1,000,000 SHARES OF COMMON STOCK FOR ISSUANCE THEREUNDER. 8 COMPENSATION AND OTHER INFORMATION CONCERNING OFFICERS, DIRECTORS AND CERTAIN STOCKHOLDERS EXECUTIVE OFFICERS The executive officers of the Company are appointed annually by the Board of Directors and serve at the discretion of the Board of Directors.

(1) The potential realizable value is based on the form of the option at its time of grant (10 years). It is calculated by assuming that the stock price on the date of grant appreciates at the indicated annual rate, compounded annually for the entire term of the option, and the option is exercised and sold on the last day of its term for the appreciated stock price. Pursuant to SEC guidelines, for options granted prior to the Company's initial public offering, the stock price on the date of grant is deemed to be equal to the initial public offering price of $18.00 per share. The 5% and 10% assumed rates of appreciation are mandated by the rules of the SEC and do not represent the Company's estimate or projection of the future common stock price. The Company does not provide assurance to any executive officer or any other holder of the Company's securities that the actual stock price appreciation over the ten year option term will be at the assumed 5% and 10% levels or at any other defined level. Unless the market price of the common stock does in fact appreciate over the option term, no value will be realized from the option grants made to the executive officers. Pursuant to stock option agreements between the Company and its employees, each of its employees are entitled to exercise their options prior to vesting. If they exercise their options prior to vesting, they will receive restricted shares which will vest in accordance with the normal vesting schedule set forth in their stock option agreement and are subject to repurchase by the Company if they cease to be employed by the Company. 12 AGGREGATED OPTION/SAR EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR END OPTION/SAR VALUES The following table shows for fiscal year ended December 31, 2000 certain information regarding options exercised by, and held at year end by, the Named Executive Officers: NUMBER OF SECURITIES UNDERLYING VALUE OF UNEXERCISED IN- NUMBER OF UNEXERCISED OPTIONS/SARS THE-MONEY OPTIONS/SARS SHARES AT DECEMBER 31, 2000(2) AT DECEMBER 31, 2000 (3) ACQUIRED ON VALUE --------------------------- --------------------------- NAME EXERCISE REALIZED ($)(1) EXERCISABLE UNEXERCISABLE EXERCISABLE UNEXERCISABLE - ---- ----------- --------------- ----------- ------------- ----------- ------------- Jack Lief..................... 162,500 $20,000 -- 200,000 $ -- $ -- Dominic P.

EMPLOYMENT AGREEMENTS Each Named Executive Officer serves at the discretion of the Board of Directors. The Company does not have any written employment agreements or any change-of-control plans or arrangements with any Named Executive Officer. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors has furnished the following report on its policies with respect to the compensation of executive officers of the Company. The report is not deemed to be "soliciting material" or to be "filed" with the SEC, or subject to the SEC's proxy rules or to the liabilities of Section 18 of the Exchange Act, and the report shall not be deemed incorporated by reference into any prior or subsequent filing by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent that the Company specifically incorporates it by reference into any such filing. Decisions regarding compensation of the Company's executive officers generally are made by the Compensation Committee of the Board of Directors. The Committee is responsible for reviewing the executive salary and benefits structure of the Company at least annually to insure its competitiveness within the Company's industry. All decisions of the Compensation Committee regarding the compensation of the Company's executive officers are reviewed by the Board of Directors, except for decisions regarding grants under the Company's option plans, which are made by the Stock Option Committee. During the fiscal year ended December 31, 2000, Mr. Lief, Dr. Steinmetz and Dr. Ryser served as members of the Compensation Committee. 13 GENERAL EXECUTIVE COMPENSATION POLICY The Company's executive compensation policy is designed to attract to the Company qualified individuals who have the potential as executive officers to contribute to the long-term growth and success of the Company and thereby enhance stockholder value, to motivate such executive officers to perform at the highest of professional levels so as to maximize their contribution to the Company and to retain such executive officers in the employ of the Company. Accordingly, the Company's executive compensation policy is to offer the Company's executive officers competitive compensation opportunities which are tied to their contribution to the growth and success of the Company and their personal performance. Each executive officer's compensation package is comprised of two elements: (i) salary, which reflects individual performance and is designed primarily to be competitive with compensation levels in the industry, and (ii) periodic stock option grants, which strengthen the mutuality of interests between the executive officer and the Company's stockholders. As a general matter, the salary for each executive officer is initially established through negotiation at the time the officer is hired, taking into account such officer's qualifications, experience, prior salary, and competitive salary information. Year-to-year adjustments to each executive officer's salary are based upon personal performance for the year, changes in the general level of salaries of persons in comparable positions within the industry, and the average merit salary increase for such year for all employees of the Company established by the Compensation Committee, as well as other factors the Compensation Committee judges to be pertinent during an assessment period. In making salary decisions, the Committee exercises its judgment to determine the appropriate weight to be given to each of these factors. The Board believes that stock options provide the Company's executive officers with the opportunity to purchase and maintain an equity interest in the Company and to share in the appreciation of the value of the Company's common stock. The Board believes that stock options directly motivate an executive to maximize long-term stockholder value. The options also utilize vesting periods (generally four years) that encourage key executives to continue in the employ of the Company. The Board considers the grant of each option subjectively, considering factors such as the individual performance of the executive officer and the anticipated contribution of the executive officer to the attainment of the Company's long-term strategic performance goals. Stock options granted in prior years are also taken into consideration. IMPLEMENTATION OF EXECUTIVE COMPENSATION POLICY The following summary describes the manner in which the Compensation Committee's executive compensation policy was implemented with respect to the fiscal year ended December 31, 2000. Also summarized below are some of the more important factors which were considered in establishing the components of each executive officer's compensation package for the 2000 fiscal year. Additional factors were also taken into account, and the Compensation Committee may, in its discretion, apply entirely different factors, particularly different measures of performance, in setting executive compensation for future fiscal years, but it is expected that all compensation decisions will be designed to further the general executive compensation policy set forth above. SALARY. Each year, the Chief Executive Officer recommends to the Compensation Committee new salary levels for the Company's executive officers. In formulating such recommendations, the Chief Executive Officer considers industry, peer group and national surveys of compensation, as well as the past and expected future contributions of the individual executive officers. The Compensation Committee then reviews the recommendations in light of its assessment of each officer's past performance and its expectation as to future contributions, and arrives at new salary levels for each of the executive officers, including the Chief Executive Officer. These new salary levels are then recommended by the Compensation Committee to the Board of Directors for approval. STOCK OPTION GRANTS. During 2000, all grants of stock options by the Company to its executive officers were made pursuant to its Amended and Restated 1998 Equity Compensation Plan and its 2000 Equity 14 Compensation Plan. During 2000, the Compensation Committee approved the grant of stock options to all of its executive officers in respect of their performance during the fiscal year ending December 31, 2000. In determining the number of shares of common stock covered by each of these grants, the Compensation Committee considered the same factors which it generally considers in determining the salaries of executive officers. These grants were also designed to further the Company's general executive compensation policy. CEO COMPENSATION In setting the compensation payable to Mr. Lief, the Compensation Committee has sought to be competitive with other companies in the industry, while at the same time tying a significant portion of such compensation to the Company's performance. Mr. Lief's salary for the fiscal year ended December 31, 2000, was established based upon the Compensation Committee's evaluation of the Company's performance and Mr. Lief's personal performance, as well as its objective of having Mr. Lief's salary remain competitive with salaries being paid to similarly situated chief executive officers. Accordingly, his 2000 salary was set by the Compensation Committee at $450,000. The other component of Mr. Lief's compensation in respect of the fiscal year ended December 31, 2000, was entirely dependent upon Mr. Lief's performance during such year, which was in turn tied directly to the Company's performance. The Compensation Committee determined to award Mr. Lief stock options to purchase 300,000 shares of common stock. This award reflected the Compensation Committee's assessment of his favorable performance, which included his satisfaction of the performance goals established by the Compensation Committee at the beginning of the fiscal year ended December 31, 2000, as well as the corporate performance of the Company during such year. In particular, the Compensation Committee considered the completion of an Initial Public Offering ("IPO") by the Company, the continued management performance and success of the members of the Executive Committee reporting to Mr. Lief, scientific progress made by the Company, the progress made in the Company's business development activities, as well as the Company's success in securing capital, prior to the IPO, sufficient to assist it in furthering its strategic performance objectives. 200,000 stock options were granted at exercise prices equal to 85% of the fair market value of the common stock on the date of grant and are subject to vesting. An additional 100,000 stock options were granted to Mr. Lief prior to the IPO with an exercise price of $0.60 per share. Submitted by the Members of the Compensation Committee Jack Lief Stefan Ryser, Ph.D. Michael Steinmetz, Ph.D. PERFORMANCE GRAPH The following is a line graph comparing the cumulative total return to stockholders (change in stock price plus reinvested dividends) of the Company's common stock from July 28, 2000 (the date of the Company's initial public offering) through December 31, 2000 to the cumulative total return over such period to: the Center for Research in Securities Prices ("CRSP") Total Return Index for the Nasdaq Stock Market (U.S. Companies) (the "Nasdaq Composite Index") and the CRSP Total Return Index for the Nasdaq Pharmaceutical Stocks (the "Nasdaq Pharmaceutical Index"). In establishing the starting point on the line graph, we used the closing price of the Company's common stock on July 28, 2000 of $25.00 as required by SEC guidelines. The graph assumes the investment of $100 and the reinvestment of dividends, although dividends have not been declared on the Company's common stock, and is based on the returns of the component 15 companies weighted according to their market capitalizations as of the end of each monthly period for which returns are indicated. The performance shown is not necessarily indicative of future price performance. The information contained in the Performance Graph is not deemed to be "soliciting material" or to be "filed" with the SEC, or subject to the SEC's proxy rules or to the liabilities of Section 18 of the Exchange Act, and shall not be deemed incorporated by reference into any prior or subsequent filing by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent that the Company specifically incorporates it by reference into any such filing.

(a) A participant may withdraw all but not less than all the payroll deductions credited to his or her account and not yet used to exercise his or her option under the Plan at any time by giving written notice to the Company's payroll office in the form of EXHIBIT B attached to this Plan. All of the participant's payroll deductions credited to his or her account shall be paid to such participant promptly after receipt of notice of withdrawal and such participant's option for the Offering Period shall be automatically terminated, and no further payroll deductions for the purchase of shares shall be made for such Offering Period. If a participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of the succeeding Offering Period unless the participant delivers to the Company's payroll office a new subscription agreement. (b) A participant's withdrawal from an Offering Period shall not have any effect upon his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the participant withdraws. 11. TERMINATION OF EMPLOYMENT. Upon a participant's ceasing to be an Employee, for any reason, he or she shall be deemed to have elected to withdraw from the Plan and the payroll deductions credited to such participant's account during the Offering Period but not yet used to exercise the option shall be returned to such participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15 hereof, and such participant's option shall be automatically terminated. 12. INTEREST. No interest shall accrue on the payroll deductions of a participant in the Plan. 13. STOCK. (a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of shares of the Company's Common Stock which shall be made available for sale under the Plan shall be One Million (1,000,000) shares. (b) The participant shall have no interest or voting rights in shares covered by his or her option until such option has been exercised. B-6 (c) Shares to be delivered to a participant under the Plan shall be registered in the name of the participant or in the name of the participant and his or her spouse. 14. ADMINISTRATION. The Plan shall be administered by the Board or a committee of members of the Board appointed by the Board. The Board or its committee shall have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and to adjudicate all disputed claims filed under the Plan. Every finding, decision and determination made by the Board or its committee shall, to the full extent permitted by law, be final and binding upon all parties. 15. DESIGNATION OF BENEFICIARY. (a) A participant may file with the Company's payroll office a written designation of a beneficiary who is to receive any shares and cash from the participant's account under the Plan in the event of such participant's death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such participant of such shares and cash. In addition, a participant may file with the Company's payroll office a written designation of a beneficiary who is to receive any cash from the participant's account under the Plan in the event of such participant's death prior to the exercise of the option. If a participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective. (b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant's death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 16. TRANSFERABILITY. Neither payroll deductions credited to a participant's account nor any rights with regard to the exercise of an option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof. 17. USE OF FUNDS. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. 18. REPORTS. Individual accounts shall be maintained for each participant in the Plan. Statements of account shall be given to participating Employees at least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any. 19. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, LIQUIDATION, MERGER OR ASSET SALE. (a) CHANGES IN CAPITALIZATION. Subject to any required action by the stockholders of the Company, the Reserves, the maximum number of shares each participant may purchase each Purchase Period (pursuant to Section 7), as well as the price per share and the number of shares of Common Stock covered by each option under the Plan which have not yet been exercised shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of shares of Common Stock effected without B-7 receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration". Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an option. (b) DISSOLUTION OR LIQUIDATION. In the event of a proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Board. The New Exercise Date shall be before the date of the Company's proposed dissolution or liquidation. The Board shall notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant's option has been changed to the New Exercise Date and that the participant's option shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10 hereof. (c) MERGER OR ASSET SALE. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding option shall be assumed or an equivalent option substituted by the successor corporation or a parent or subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, any Purchase Periods then in progress shall be shortened by setting a new Exercise Date (the "New Exercise Date") and any Offering Periods then in progress shall end on the New Exercise Date. The New Exercise Date shall be before the date of the Company's proposed sale or merger. The Board shall notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant's option has been changed to the New Exercise Date and that the participant's option shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10 hereof. 20. AMENDMENT OR TERMINATION. (a) The Board of Directors of the Company may at any time and for any reason terminate or amend the Plan. Except as provided in Section 19 hereof, no such termination can affect options previously granted, provided that an Offering Period may be terminated by the Board of Directors on any Exercise Date if the Board determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its stockholders. Except as provided in Section 19 and this Section 20 hereof, no amendment may make any change in any option theretofore granted which adversely affects the rights of any participant. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation or Nasdaq stock market rule or stock exchange rule), the Company shall obtain stockholder approval in such a manner and to such a degree as required. (b) Without stockholder consent and without regard to whether any participant rights may be considered to have been "adversely affected," the Board (or its committee appointed pursuant to Section 14) shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in the Company's processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each participant properly correspond with amounts withheld from the B-8 participant's Compensation, and establish such other limitations or procedures as the Board (or its committee) determines in its sole discretion advisable which are consistent with the Plan. (c) In the event the Board determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Board may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequences including, but not limited to: (1) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price; (2) shortening any Offering Period so that the Offering Period ends on a new Exercise Date, including an Offering Period underway at the time of the Board action; and (3) allocating shares. Such modifications or amendments shall not require stockholder approval or the consent of any Plan participants. 21. NOTICES. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 22. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the rules and regulations promulgated thereunder, and the requirements of the Nasdaq Stock Market or any stock exchange upon which the shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law. 23. TERM OF PLAN. The Plan shall become effective upon the earlier to occur of its adoption by the Board of Directors or its approval by the stockholders of the Company. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 20 hereof. 24. MISCELLANEOUS. (a) ADMINISTRATIVE COSTS. The Company shall pay the administrative expenses associated with the operation of the Plan (other than brokerage commissions resulting from sales of Common Stock directed by Employees). (b) NO EMPLOYMENT RIGHTS. Participation in the Plan shall not give an Employee any right to continue in the employment of the Company, and shall not affect the right of the Company to terminate the Employee's employment at any time, with or without cause. (c) REPURCHASE OF STOCK. The Company shall not be required to purchase or repurchase from any Employee any of the shares of Common Stock that the Employee acquires under the Plan. (d) INTERNAL REVENUE CODE AND ERISA CONSIDERATIONS. The Plan is intended to constitute an "employee stock purchase plan" within the meaning of section 423 of the Internal Revenue Code of 1986, as amended, and the regulations thereunder. The provisions of the Plan, accordingly, shall be construed so as to comply with the requirements of that section of the Code or any successor provision, and the regulations thereunder. The Plan is not intended and shall not be construed as B-9 constituting an "employee benefit plan," within the meaning of section 3(3) of the Employee Retirement Income Security Act of 1974, as amended. (e) HEADINGS, CAPTIONS, GENDER. The headings and captions herein are for convenience of reference only and shall not be considered as part of the text. The masculine shall include the feminine, and vice versa. (f) SEVERABILITY OF PROVISIONS, PREVAILING LAW. The provisions of the Plan shall be deemed severable. In the event any such provision is determined to be unlawful or unenforceable by a court of competent jurisdiction or by reason of a change in an applicable statute, the Plan shall continue to exist as though such provision had never been included therein (or, in the case of a change in an applicable statute, had been deleted as of the date of such change). The Plan shall be governed by the laws of the State of California to the extent such laws are not in conflict with, or superseded by, federal law. [END OF PLAN] B-10 [ARENA PHARMACEUTICALS, INC.
