On April 2, 2003, the Company had issued and outstanding 71,999,924 common shares, par value US$.0005 per share ("Common Shares"). Holders of Common Shares are entitled to one vote for each share held. All registered shareholders can vote by paper proxy or by telephone by following the instructions included with their proxy card. Shareholders whose Common Shares are registered in the name of a bank or brokerage firm should follow the instructions provided by their bank or brokerage firm on voting their Common Shares. Shareholders whose Common Shares are registered in the name of a bank or brokerage firm participating in the ADP Investor Communication Services online program may appoint a proxy to vote electronically through the Internet. Instruction forms will be provided to shareholders whose bank or brokerage firm is participating in ADP's program. Signing and returning the proxy card or submitting the proxy by telephone or through the Internet does not affect the right to vote in person at the annual general meeting. In the case of registered shareholders, a proxy may be revoked at any time prior to its exercise by (a) giving written notice of such revocation to the Secretary of the Company at the Company's principal office, 2910 Seventh Street, Berkeley, California 94710, (b) appearing and voting in person at the annual general meeting, (c) properly completing and executing a later-dated proxy and delivering it to the Company at or before the annual general meeting or (d) retransmitting a subsequent proxy by telephone before the annual general meeting. Presence without voting at the annual general meeting will not automatically revoke a proxy, and any revocation during the meeting will not affect votes previously taken. Shareholders whose Common Shares are registered in the name of a bank or brokerage firm should follow the instructions provided by -2- their bank or brokerage firm on revoking their previously appointed proxies. Abstentions and broker non-votes are each included in the number of Common Shares present and voting for purposes of establishing a quorum but are not counted in tabulations of the votes cast on proposals presented to shareholders. The Company will bear the entire cost of solicitation, including preparation, assembly, printing, and mailing of this proxy statement, the proxy card, and any additional material furnished to shareholders. Copies of solicitation material will be furnished to brokerage houses, fiduciaries, and custodians holding in their names Common Shares that are beneficially owned by others to forward to such beneficial owners. The solicitation of proxies may be supplemented by one or more of telephone, telegram, or personal solicitation by directors, officers, or employees of the Company for no additional compensation. We have also engaged Georgeson Shareholder Communications Inc. to assist in such solicitation at an estimated fee of $7,500 plus disbursements. Shareholders appointing a proxy to vote through the Internet should understand that there may be costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, that must be borne by the shareholder. The Company intends to mail this proxy statement and make it available on the Internet on or about April 10, 2003. SHARE OWNERSHIP The following table sets forth as of April 2, 2003, certain information regarding all shareholders known by the Company to be the beneficial owners of more than 5% of the Company's outstanding Common Shares and regarding each director, each executive officer and all directors and current executive officers as a group, together with the approximate percentages of outstanding Common Shares owned by each of them.

Under this agreement, Mr. Castello also receives all standard Company employee benefits and supplemental life insurance for the amount that an annual premium of $18,000 provides. The agreement also provides for a grant of options for 500,000 Common Shares under the Company's 1981 Share Option Plan (the "Option Plan"), which was made in 1992. Mr. Castello's employment may be terminated, with or without cause, at the will of either party. If terminated by the Company for any reason other than due cause or by Mr. Castello for good reason, Mr. Castello must be paid his then current base salary and benefits for one year. If terminated for due cause, he is entitled to no further compensation. Good reason includes, in the context of a change of control, the assignment to Mr. Castello of duties inconsistent with his prior duties; his removal from, or failure to re-elect him to, any position he held immediately prior to the change in control; any termination by the Company within three years of the change of control other than for due cause or upon disability or death; a good faith determination by Mr. Castello that changes in circumstances resulting from the change in control leave him substantially unable to perform his duties, after notice; the failure of the Company's successor or the transferee of its assets or business to assume its obligations under the agreement; or, a significant relocation of the Company's executive offices. Good reason also includes any reduction in base pay or benefits or any breach of the agreement by the Company. The Company has entered into an employment agreement with Dr. Scannon, dated as of March 26, 2003, that provides for his employment as Senior Vice President and Chief Scientific and Medical Officer at a salary of $340,000 per year. Under this agreement, Dr. Scannon is entitled to participate in any benefit plan for which key executives of the Company are eligible, including the Management Incentive Compensation Plan established effective July 1, 1993 (as amended, the "Incentive Plan"). A loan to Dr. Scannon with a remaining balance of $100,982.45, bearing interest at 6% per annum and secured by a pledge of certain of the Company's Common Shares, was scheduled to mature on March 26, 2003 and was paid in full by Dr. Scannon on March 21, 2003. The loan was originally made to Dr. Scannon in 1993 and had been extended for nine additional years. A total of $425,682.71 in principal and interest payments have been -11- received by the Company. Upon termination of his employment for any reason other than cause, or upon resignation, Dr. Scannon must be paid his then current base salary and benefits for one year. The Company has entered into an employment agreement with Mr. Davis dated as of April 1, 1994 that provides for his employment as Chief Financial Officer at an initial salary of $200,000 per year. Under this agreement, Mr. Davis received a one-time transition allowance in the amount of $35,000 and is entitled to participate in any benefit plan for which executives of the Company are eligible. In addition, the agreement provides for an initial grant of options for 60,000 Common Shares under the Option Plan, which was made in 1994, as well as participation in the Incentive Plan. Mr. Davis' employment agreement provides no additional compensation in the event of a change of control but provides a minimum severance amount equal to six months of base salary at the time of termination. Compensation Committee Report on Executive Compensation The Company's compensation program for officers (including the named executive officers) is administered by the Compensation Committee of the Board of Directors (the "Committee"), which is composed of two non-employee directors. Following review and approval by the Committee, all issues pertaining to officer compensation are submitted to the full Board of Directors for approval. The primary objectives of the Company's compensation program are to enable the Company to attract, motivate and retain outstanding individuals and align their success with that of the Company's shareholders through the creation of shareholder value and achievement of strategic corporate objectives. The level of compensation paid to an officer is determined on the basis of the individual's overall experience, responsibility, performance and compensation level in his or her prior position (for newly hired officers), the individual's overall performance and compensation level at the Company during the prior year (for current employees), the compensation levels of similarly situated individuals in the pharmaceutical and biotechnology industries (including, but not limited to, the biotechnology companies included in the AMEX Biotechnology Index) and other labor markets in which the Company competes for employees, the performance of the Company's Common Shares during the prior fiscal year and such other factors as may be appropriately considered by the Board of Directors, by the Committee and by management in making its initial proposals to the Committee. -12- Mr. Castello's compensation for 2002 was determined after considering the general factors described above and the terms of his existing employment contract. In 1992, the Committee approved, and recommended that the Board approve, the terms of Mr. Castello's employment contract, as more fully described under "Employment Contracts and Termination of Employment and Change-in-Control Arrangements," because it felt that the terms thereof were necessary in order to attract a candidate of Mr. Castello's experience and reputation in the pharmaceutical industry, which in turn was deemed necessary in order to enable the Company to advance toward its long-range goal of becoming a pharmaceutical company with commercially viable products. Mr. Castello has not received a salary increase since his employment contract was executed in 1992. The principal methods for long-term incentive compensation are the Option Plan and Restricted Share Plan (the "Restricted Plan"), and compensation thereunder principally takes the form of incentive and non-qualified option grants. These grants are designed to promote the convergence of long-term interests between the Company's key employees and its shareholders; specifically, the value of options granted will increase or decrease with the value of the Company's Common Shares. In this manner, key individuals are rewarded commensurately with increases in shareholder value. These grants also typically include a 5-year vesting period to encourage continued employment. The size of a particular option grant is determined based on the individual's position with and contribution to the Company. For grants during 2002, the number of options granted were determined based on the numbers of options granted to such individuals in the previous fiscal year, the aggregate number of options held by each such individual, the number of options granted to similarly situated individuals in the pharmaceutical and biotechnology industries, the price of the Company's Common Shares relative to other companies in such industries and the resulting relative value of such options; no specific measures of corporate performance were considered. Certain employees are also compensated through the Incentive Plan, in which management employees (other than the Chief Executive Officer), as well as certain additional discretionary participants chosen by the Chief Executive Officer, are eligible to participate. Under the Incentive Plan, at the beginning of each fiscal year, the Board of Directors (with advice from the Committee) establishes a target incentive compensation pool, which is then adjusted at year-end to reflect the Company's performance in achieving its corporate objectives. -13- After each fiscal year, the Board of Directors and the Committee make a determination as to the performance of the Company and Incentive Plan participants in meeting corporate objectives and individual objectives, which are determined from time to time by the Board of Directors in its sole discretion and which included for 2002: a target level of cash at year end; generation of current income; progress toward collaborations, potential partnerships or financing arrangements; and various objectives tied to development of the Company's product lines. Awards to Incentive Plan participants vary depending upon the level of achievement of corporate objectives, the size of the incentive compensation pool and the Incentive Plan participants' base salaries and performance during the fiscal year as well as their expected ongoing contribution to the Company. The Company must meet a minimum percentage of its corporate objectives (currently 70%) before any awards are made under the Incentive Plan. Awards under the Incentive Plan vest over a three-year period with 50% of each award payable during the first quarter of the following fiscal year, and 25% payable on each of the next two annual distribution dates, so long as the participant remains an employee of the Company. The 50% on the first distribution date is payable half in cash and half in Common Shares. The balance on the next two annual distribution dates is payable, at the election of the participant, all in cash, all in Common Shares or half in cash and half in Common Shares or, for elections not made in a timely manner, all in Common Shares. All share issuances under the Incentive Plan are made pursuant to the Restricted Plan. For 2002, the Committee and the Board of Directors determined that management had met a percentage of the corporate objectives summarized above in excess of the 70% minimum required by the Incentive Plan in order to make awards thereunder. For 2002, 70 individuals were determined to be eligible to participate in the Incentive Plan, including all of the executive officers named in the "Summary Compensation Table" above other than Mr. Castello. Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), generally limits the deductible amount of annual compensation paid to certain individual executive officers (i.e., the chief executive officer and the four other most highly compensated executive officers of the Company) to no more than $1 million. However, qualifying performance-based compensation will be excluded from the $1 million cap on deductibility, and the Committee believes, based on information currently available, that the Company's options issued to its executive officers qualify for this exclusion. Considering the current structure of executive officer -14- compensation and the availability of deferral opportunities, the Committee believes that the Company will not be denied any significant tax deduction for 2003. The Committee will continue to review tax consequences as well as other relevant considerations in connection with compensation decisions. William K. Bowes, Jr. W.

Audit Committee Report Each member of the audit committee is "independent" as defined in the listing standards of The Nasdaq Stock Market. The Company's Board of Directors has adopted a written charter for the audit committee, a copy of which is attached to this proxy statement as Annex 1. In accordance with rules recently established by the Securities and Exchange Commission, the audit committee has prepared the following report for inclusion in this proxy statement: As part of its ongoing activities, the audit committee has: o met with management periodically to consider the adequacy of the Company's internal controls and the objectivity of its financial reporting, and discussed these matters with the Company's independent auditors and with appropriate Company financial personnel; o regularly met privately with the independent auditors, who have unrestricted access to the committee; o recommended to the Board of Directors the appointment of the independent auditors and reviewed periodically their performance and independence from management; o reviewed the Company's financing plans and reported recommendations to the full Board of Directors for approval and to authorize action; o reviewed and discussed with management the Company's audited consolidated financial statements for the fiscal year ended December 31, 2002; o discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, Communications with Audit Committees, as amended; and -22- o received the written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, and discussed with the independent auditors their independence. Based on the review and discussions referred to above, the audit committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2002. Steven C. Mendell James G. Andress Patrick J. Zenner ITEM 2 - APPOINTMENT OF INDEPENDENT AUDITORS The Board of Directors, on the recommendation of its audit committee, recommends the appointment of Ernst & Young LLP ("Ernst & Young") to serve as the Company's independent auditors for 2003. Ernst & Young has been acting as the Company's independent auditors since fiscal year 1998. Audit Fees. The aggregate fees for professional services rendered by Ernst & Young for the audit of the Company's annual financial statements for the 2002 fiscal year and the reviews of the financial statements included in the Company's Form 10-Qs for that fiscal year were $213,923. The audit fees for the 2002 fiscal year exclude fees totaling $82,900 related to statutory and regulatory filings under Form S-3. For 2002, this amount is included in All Other Fees. Financial Information Systems Design and Implementation Fees. The Company did not engage Ernst & Young to render services regarding financial information systems design and implementation (as defined in Rule 2-01(c)(4) of Regulation S-X under the Securities Exchange Act of 1934) for the 2002 fiscal year. All Other Fees. The aggregate fees billed for services rendered by Ernst & Young, other than the services covered in the two immediately preceding paragraphs of this section, for the 2002 fiscal year were $163,025. The audit committee considered whether the provision of the services covered in the three immediately preceding paragraphs -23- of this section is compatible with maintaining Ernst & Young's independence. The recommendation to appoint Ernst & Young and the authorization of the Board of Directors to agree to Ernst & Young's fee are being submitted to the shareholders at the annual general meeting. If such appointment is not made, the Board of Directors will consider other auditors for appointment. The Board of Directors recommends a vote "FOR" the appointment of Ernst & Young as the Company's independent auditors for the 2003 fiscal year and the authorization of the Board of Directors to agree to Ernst & Young's fee. A representative of Ernst & Young is expected to be present at the meeting with an opportunity, if desired, to make a statement and to respond to your questions. ITEM 3 - RECEIPT OF AUDITED FINANCIAL STATEMENTS In accordance with Bermuda company law and practice, the Company's audited financial statements for fiscal year 2002 will be laid before the annual general meeting. No shareholder action is required in connection therewith. ITEM 4 - ADDITION OF SHARES TO OPTION PLAN AND RESTRICTED PLAN The Board of Directors has adopted, subject to shareholder approval, amendments to the Option Plan and the Restricted Plan (together, the "Share Option Plans") to increase the number of Common Shares issuable over the terms of the Share Option Plans by 2,500,000 shares to 11,150,000 shares in the aggregate. The essential features of the Share Option Plans are summarized below under "Description of Share Option Plans." Recommendation At the annual general meeting, the Company's shareholders will be asked to approve the proposal to amend the Share Option Plans to increase the number of shares issuable over the terms of the Share Option Plans by 2,500,000 shares to 11,150,000 shares in the aggregate. The Board of Directors believes that approval of the proposed amendment is in the best interests of the Company, its shareholders and its employees because it will assist the Company in continuing to attract and retain the services of outstanding employees and will enable the Company to use this type of long-term incentive compensation at levels commensurate with its peers, both in its -24- region and in its business sector. For these reasons, the Board unanimously recommends a vote "FOR" approval. Approval of the amendment requires the affirmative vote of the holders of a majority of the votes cast at the annual general meeting on the proposal. ITEM 5 - ADDITION OF SHARES TO RESTRICTED PLAN The Board of Directors has adopted, subject to shareholder approval, an amendment to the Restricted Plan to increase the number of Common Shares issuable over the term of the plan by 250,000 shares to 1,500,000 shares in the aggregate. The essential features of the Restricted Plan are summarized below under "Description of Share Option Plans." Recommendation At the annual general meeting, the Company's shareholders will be asked to approve the proposal to amend the Restricted Plan to increase the number of shares issuable over the term of the Restricted Plan by 250,000 shares to 1,500,000 shares in the aggregate. The Board of Directors believes that approval of the proposed amendment is in the best interests of the Company, its shareholders and its employees because it will assist the Company in continuing to attract and retain the services of outstanding employees and unanimously recommends a vote "FOR" approval. Approval of the amendment requires the affirmative vote of the holders of a majority of the votes cast at the annual general meeting on the proposal. DESCRIPTION OF SHARE OPTION PLANS Background The Share Option Plans are designed to encourage equity ownership of the Company by the employees who are primarily responsible for its management, growth and financial success, and to assist the Company in attracting and retaining the services of such employees (see "Compensation Committee Report on Executive Compensation" above). The essential features of the Option Plan and the Restricted Plan are summarized below. These summaries do not purport to be complete descriptions of the Share Option Plans. Copies of actual plan documents may be obtained by contacting the Secretary of the Company. Description of Option Plan -25- Of the 8,650,000 Common Shares currently authorized for issuance under the Option Plan and the Restricted Plan, approximately 1,692,869 shares had been issued upon the exercise of options granted under the Option Plan, 5,035,988 shares were subject to outstanding options under the Option Plan, and 1,024,756 shares were available for issuance under future option grants to be made under the Option Plan, as of the close of business on April 2, 2003. The expiration dates for all such outstanding options range from October 26, 2004 (at the earliest) to February 26, 2013 (at the latest). The Common Shares issuable over the term of the Option Plan will be made available from authorized but unissued Common Shares. Each option will have an exercise price per share of not less than 100% of the fair market value per Common Share on the date of grant. The Option Plan's term expires on November 15, 2011. Description of Restricted Plan Of the 1,250,000 Common Shares currently authorized for issuance under the Restricted Plan (subject to the limitation that not more than 8,650,000 shares may be issued in the aggregate under the Restricted Plan and the Option Plan), approximately 271,906 shares had been issued either upon the exercise of granted options or the direct issuance of shares under the Restricted Plan, 404,795 shares were subject to outstanding options under the Restricted Plan, and 353,613 shares were available for issuance under future option grants or direct issuances to be made under the Restricted Plan, as of the close of business on April 2, 2003. The expiration dates for all such outstanding options range from July 13, 2004 (at the earliest) to November 1, 2012 (at the latest). The Restricted Plan authorizes the grant of options to purchase Common Shares (the "Option Grant Program") as well as direct Common Share issuances (the "Share Issuance Program"). Such shares will be made available from authorized but unissued Common Shares. Each option granted under the Option Grant Program will have an exercise price of not less than 85% of fair market value per Common Share on the date of grant. The purchase price for shares issued under the Share Issuance Program may not be less than 85% of fair market value per Common Share on the issuance date, which value will be discounted if such shares are subject to the Company's right of first refusal described below. The Restricted Plan's term expires on November 15, 2011. -26- Provisions Common to Both Plans Key employees (including officers and directors) of the Company (or its subsidiaries) who provide valuable services to the Company (or its subsidiaries) are eligible to participate in the Share Option Plans (each, a "Participant"). Directors who are not employees of the Company are not eligible to participate in either Share Option Plan. The Share Option Plans provide that each such plan will be administered by either the full Board of Directors or, if appointed by the Board, a committee thereof comprised of at least two "Non-Employee Directors" within the meaning of Rule 16b-3 of the Securities Exchange Act of 1934, as such term is interpreted from time to time. Currently, the Compensation Committee administers the Share Option Plans as each relates to individuals other than directors, officers or ten-percent shareholders of the Company. The Compensation Committee's authority to grant options under the Share Option Plans and to issue shares under the Restricted Plan is limited to 15,000 shares per individual. In all other respects, the Share Option Plans are administered by the Board. The Board and, with respect to individuals who are not directors, officers or ten-percent shareholders of the Company, the Compensation Committee (the "Plan Administrators") are authorized (subject to the provisions of the Share Option Plans) to establish such rules and regulations as they may deem appropriate for the proper administration of the Share Option Plans. Each option, whether granted under the Option Plan or the Option Grant Program of the Restricted Plan, will be exercisable at such times, during such period or periods, and for such number of shares as the relevant Plan Administrator determines. No such granted option may have a term in excess of ten years from the grant date. The number of Common Shares for which options or SARs may be granted to any Participant under the Option Plan or the Option Grant Program or which may be issued to any Participant under the Share Issuance Program is limited to not more than 1,000,000 during any calendar year. Exercise of Options. The exercise price of options granted under either plan will be immediately due upon exercise of the option and may be paid (i) in cash; (ii) in Common Shares having a fair market value on the date the option is exercised equal to the option price; (iii) in a combination of cash and Common Shares valued at fair market value on the day the option is exercised; or (iv) through a broker-dealer sale and remittance procedure pursuant -27- to which shares acquired under the option are sold immediately and there is paid to the Company, out of the sale proceeds, an amount equal to the option price for the acquired shares plus all applicable withholding taxes. For all purposes of valuation under either of the Share Option Plans, the fair market value of the Common Shares on any relevant date will be the closing sale price per Common Share, as reported for such date through The Nasdaq Stock Market. The relevant Plan Administrator may also assist any optionee (other than a director) in the exercise of an option by authorizing a loan from the Company, by permitting the optionee to pay the option price in installments over a period of years or by authorizing a guarantee by the Company of a third party loan to the optionee, the terms and conditions of which will be established by the relevant Plan Administrator in its sole discretion. However, the maximum credit available to the optionee may not exceed the option price payable for the purchased shares, plus any tax liability. Transfer. The Share Option Plans provide that non-qualified options granted thereunder may be granted on terms permitting transfer to immediate family members of the optionee (or an entity comprised entirely of the optionee and such immediate family members) in certain circumstances. Termination of Employment. Should an optionee under either Share Option Plan cease to be an employee or consultant of the Company for any reason (other than death, certain retirements, termination for cause or unauthorized disclosure, as described below), such optionee (or its permitted transferee) will not have more than a twelve (12) month period following the date of such cessation of status in which to exercise any outstanding options. For options granted on or after February 25, 2003, should an optionee cease to be an employee or consultant by reason of death, the options will become fully exercisable and shall remain exercisable for a twelve (12) month period following the date of death. For options granted on or after February 25, 2003, should an optionee cease to be an employee or consultant by reason of retirement at or after age fifty-five (55) and where optionee's age plus service exceed seventy (70), the options will become fully exercisable, and, in the case of the Restricted Plan shall remain exercisable for a twelve (12) month period following such retirement, or in the case of the Option Plan shall remain exercisable for the full option term as if the optionee had continued in employment. In all of the cases above, under no circumstances may any options be exercised after the specified expiration date of the option term. Should an optionee be terminated for cause (including, but not limited to, any act of dishonesty, -28- willful misconduct, fraud or embezzlement or any unauthorized disclosure or use of confidential information or trade secrets), or should an optionee make or attempt to make any unauthorized use or disclosure of confidential information or trade secrets, then all outstanding options shall immediately terminate and cease to be exercisable. Share Appreciation and Repurchase Rights. The Option Plan and the Option Grant Program each include a share appreciation right ("SAR") feature whereby the relevant Plan Administrator has the authority to grant one or more optionees the right, exercisable upon such terms and conditions as such Plan Administrator deems appropriate, to surrender all or part of an unexercised option and to receive in exchange therefore an amount equal to the excess of (i) the fair market value (on the date of surrender) of the number of vested shares for which the surrendered option is at the time exercisable over (ii) the aggregate option price payable for such vested shares, payable in Common Shares valued at fair market value on the date of surrender, in cash, or partly in shares and partly in cash. To date, no SARs have been granted. Acceleration of Options. Pursuant to certain corporate transactions, including: a merger or acquisition in which the Company is not the surviving entity; the sale, transfer or other disposition of all or substantially all of the assets of the Company; or any other business combination in which 50% or more of the Company's outstanding voting shares is transferred to different holders in a single transaction or a series of related transactions, all options at the time outstanding and not then otherwise fully exercisable will immediately, prior to the specified effective date of such corporate transaction, become fully exercisable for up to the total number of Common Shares purchasable thereunder. Amendment. The Share Option Plans permit the grant of options to purchase Common Shares in excess of the number of shares then available for issuance. Any option so granted cannot be exercised prior to shareholder approval of an amendment increasing the number of shares available for issuance under the Option Plan or the Restricted Plan, as the case may be. The Board has full power and authority to amend or modify the Share Option Plans in any or all respects, except that no such amendment or modification may, without the consent of the option holders, adversely affect rights and obligations with respect to options at the time outstanding under either of the Share Option Plans, nor adversely affect the rights of any individual with respect to the Common Shares issued pursuant to the Restricted Plan -29- prior to such action, and the Board may not, without the approval of the Company's shareholders, (i) increase the maximum number of shares issuable under the Option Plan or the Restricted Plan, except for permissible adjustments in the event of certain changes in the Company's capitalization, (ii) materially increase the benefits accruing to Participants in the Share Option Plans or (iii) materially modify the eligibility requirements for participation therein. Description of Share Issuance Program Common Shares will be issued to eligible individuals under the Share Issuance Program upon such terms and conditions and for such numbers of shares as is determined by the relevant Plan Administrator and may be fully vested upon issuance or may vest over such period of time as such Plan Administrator deems appropriate. Shares may be issued under the Share Issuance Program for such consideration as the relevant Plan Administrator may from time to time determine, provided that in no event may shares be issued for consideration other than (i) cash or cash equivalents; (ii) Common Shares valued at fair market value; (iii) the promissory note of the purchaser payable to the Company's order, which may be subject to cancellation by the Company in whole or in part upon such terms or conditions as the Plan Administrator may determine; or (iv) payment effected through a broker-dealer sale and remittance procedure. If a Participant is issued shares under the Share Issuance Program which are not fully vested at the time of issuance, then such shares will be subject to certain repurchase rights of the Company, exercisable in the event the individual ceases to retain his/her employee or service status for any reason, and will allow the Company to repurchase the Participant's unvested shares at the lesser of (i) the original purchase price paid by such individual or (ii) if such shares are subject to the Company's first refusal rights, the fair market value of such shares appropriately discounted for the Company's first refusal rights. The vesting schedule applicable to each issuance will be determined by the relevant Plan Administrator at the time of issuance. The relevant Plan Administrator may accelerate the vesting of the issued shares, in whole or in part, at the time of the participant's termination. The issued shares may, in the discretion of the relevant Plan Administrator, be subject to a permanent right of first refusal. Prior to any sale or other disposition of the shares subject to such right, the Participant must first offer to sell the shares to the Company (or its assigns) at a price equal to the difference between the fair market value of the shares on the date of repurchase (determined in accordance with the normal valuation provisions -30- of the Restricted Plan, without regard to the Company's permanent right of first refusal) and the price differential determined by the relevant Plan Administrator at the time of issuance. Common Shares issued pursuant to the Incentive Plan are issued under the Share Issuance Program. Federal Income Tax Consequences The following discussion summarizes the principal federal income tax consequences of the Share Option Plans. This discussion is based on current provisions of the Code, the Treasury regulations promulgated thereunder, and administrative and judicial interpretations thereof. The summary does not address any foreign, state or local tax consequences of participation in the Share Option Plans. Share Options. In general, the grant of an option will not be a taxable event to the recipient and it will not result in a deduction to the Company. The tax consequences associated with the exercise of an option and the subsequent disposition of Common Shares acquired on the exercise of such option depend on whether the option is an incentive stock option or a non-qualified stock option. Upon the exercise of a non-qualified stock option, the Participant will recognize ordinary taxable income equal to the excess of the fair market value of the Common Shares received upon exercise over the exercise price. The Company will generally be able to claim a deduction in an equivalent amount. Any gain or loss upon a subsequent sale or exchange of the Common Shares will be capital gain or loss, long-term or short-term, depending on the holding period for the Common Shares. Generally, a Participant will not recognize ordinary taxable income at the time of exercise of an incentive stock option and no deduction will be available to the Company, provided the option is exercised while the Participant is an employee or within three months following termination of employment (longer, in the case of disability or death). If an incentive stock option granted under the Option Plan is exercised after these periods, the exercise will be treated for federal income tax purposes as the exercise of a non-qualified stock option. Also, an incentive stock option granted under the Option Plan will be treated as a non-qualified stock option to the extent it (together with other incentive stock options granted to the Participant by the Company) first becomes exercisable in any calendar year for Common Shares having a fair market value, determined as of the date of grant, in excess of $100,000. -31- If Common Shares acquired upon exercise of an incentive stock option are sold or exchanged more than one year after the date of exercise and more than two years after the date of grant of the option, any gain or loss will be long-term capital gain or loss. If Common Shares acquired upon exercise of an incentive stock option are disposed of prior to the expiration of these one-year or two-year holding periods (a "Disqualifying Disposition"), the Participant will recognize ordinary income at the time of disposition, and the Company will generally be entitled to a deduction, in an amount equal to the excess of the fair market value of the Common Shares at the date of exercise over the exercise price. Any additional gain will be treated as capital gain, long-term or short-term, depending on how long the Common Shares have been held. Where Common Shares are sold or exchanged in a Disqualifying Disposition (other than certain related party transactions) for an amount less than their fair market value at the date of exercise, any ordinary income recognized in connection with the Disqualifying Disposition will be limited to the amount of gain, if any, recognized in the sale or exchange, and any loss will be a long-term or short-term capital loss, depending on how long the Common Shares have been held. Although the exercise of an incentive stock option as described above would not produce ordinary taxable income to the Participant, it would result in an increase in the Participant's alternative minimum taxable income and may result in an alternative minimum tax liability. If an option is exercised through the use of Common Shares previously owned by the Participant, such exercise generally will not be considered a taxable disposition of the previously owned shares and, thus, no gain or loss will be recognized with respect to such previously owned shares upon such exercise. The amount of any built-in gain on the previously owned shares generally will not be recognized until the new shares acquired on the option exercise are disposed of in a sale or other taxable transaction. Share Awards. A Participant who receives a share award will generally recognize ordinary income at the time that they "vest", i.e., either when they are not subject to a substantial risk of forfeiture or when they are freely transferable. The amount of ordinary income so recognized will be the fair market value of the Common Shares at the time the income is recognized (determined without regard to any restrictions other than restrictions which by their terms will never lapse), less the amount, if any, paid for the shares. This amount is generally deductible for federal income tax purposes by the Company. Dividends paid with respect to Common -32- Shares that are nonvested will be ordinary compensation income to the Participant (and generally deductible by the Company). Any gain or loss upon a subsequent sale or exchange of the Common Shares, measured by the difference between the sale price and the fair market value on the date restrictions lapse, will be capital gain or loss, long-term or short-term, depending on the holding period for the Common Shares. The holding period for this purpose will begin on the date following the date restrictions lapse. In lieu of the treatment described above, a Participant may elect immediate recognition of income under Section 83(b) of the Code. In such event, the Participant will recognize as income the fair market value of the restricted shares at the time of grant (determined without regard to any restrictions other than restrictions which by their terms will never lapse), and the Company will generally be entitled to a corresponding deduction. Dividends paid with respect to shares as to which a proper Section 83(b) election has been made will not be deductible to the Company. If a Section 83(b) election is made and the shares are subsequently forfeited (i.e., they do not meet the conditions for "vesting"), the Participant will not be entitled to any offsetting tax deduction. Share Appreciation Rights. With respect to share appreciation rights under the Share Option Plans, generally, when a Participant receives payment with respect to a share appreciation right granted to him or her under the Share Option Plans, the amount of cash and the fair market value of any other property received will be ordinary income to such Participant and will be allowed as a deduction for federal income tax purposes to the Company. Payment of Withholding Taxes. The Company may withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy any federal, state or local withholding tax requirements associated with awards under the Plan. Limitation on Compensation in Excess of $1 Million. Section 162(m) of the Code generally limits the deductible amount of annual compensation paid (including, unless an exception applies, compensation otherwise deductible in connection with awards granted under the Plan) by a public company to a "covered employee" (i.e., the chief executive officer and four other most highly compensated executive officers of the Company) to no more than $1 million. The Company currently intends to structure share options granted under the Share Option Plans to comply with the exception to nondeductibility under Section 162(m) of the Code.

CERTAIN TRANSACTIONS Pursuant to his employment agreement, in 1993 the Company made a loan to Dr. Scannon, its Chief Scientific and Medical Officer, Senior Vice President and a Director, in the initial amount of $290,000. See "Employment Contracts and Termination of Employment and Change-in-Control Arrangements." On March 21, 2003, five days prior to the scheduled maturity date of the loan, the outstanding principal and interest in the amount of $100,982.45 were paid in full by Dr. Scannon. A total of $425,682.71 in principal and interest payments were received by the Company in connection with this loan. Compliance with Section 16(a) of the Securities Exchange Act of 1934 Section 16(a) of the Securities Exchange Act of 1934 requires the Company's executive officers and directors to file initial reports of ownership and changes in ownership with the SEC and The Nasdaq Stock Market. Such executive officers and directors are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file. Based on a review of the copies -34- of the forms furnished to the Company and written representations from the Company's executive officers and directors, other than Mr. Davis who filed late with respect to two transactions reportable on Form 4 and Mr. Dellio who filed late with respect to one transaction reportable on Form 4, all persons subject to the reporting requirements of Section 16(a) filed the required reports with respect to 2002 on a timely basis. In 2003, Mr. Margolin filed a corrected Form 4 with respect to one transaction reportable on Form 4 for a prior year. OTHER MATTERS The Board of Directors does not know of any matters to be presented at this annual general meeting other than those set forth in this proxy statement and in the notice accompanying this proxy statement. If other matters should properly come before the meeting, it is intended that the proxy holders will vote on such matters in accordance with their best judgment.

AUDIT COMMITTEE CHARTER The Audit Committee of XOMA Ltd. originally adopted an Audit Committee Charter (the "Charter") at the meeting of the Committee held on February 23, 2000, which Charter was approved by all of the Directors at a meeting on February 23, 2000 and has adopted the following amended and restated Charter at the meeting of the Committee held on October 30, 2002, which Charter was approved by all of the Directors at a meeting of the Board of Directors at XOMA Ltd. held on October 30, 2002: 1. Designation of Committee. The Audit Committee (the "Audit Committee" or the "Committee") of the Board of Directors of XOMA Ltd. (the "Company") has heretofore been designated by the Board of Directors. The Committee shall continue to function in accordance with the prior determinations of the Board of Directors, the Company's Bye-laws and this Charter, as originally adopted at the meetings of the Board of Directors and the Audit Committee both held on February 23, 2000 and as amended at the meetings of the Board of Directors and the Audit Committee both held on October 30, 2002. 2. Policy confirmation. The operation and function of the Committee is based on the recognition that the outside auditor for the Company is ultimately accountable to the shareholders of the Company, to the Board of Directors, and to the Audit Committee of the Company, and that the Audit Committee and Board of Directors, as the shareholders' representatives, have the ultimate authority and responsibility to select, evaluate and, where appropriate, replace the outside auditor (or to nominate the outside auditor to be proposed for shareholder approval in any proxy statement). 3. Auditor independence confirmation. The Audit Committee is responsible for ensuring that the outside auditor submits on a periodic (but at least annual) basis to the Audit Committee a formal written statement delineating all relationships between the auditor and the Company and the number of previous consecutive fiscal years in which each of the audit partners responsible for the audit of the Company have performed audit services for the Company. The Audit Committee is responsible for actively engaging in a dialogue with the outside auditor with respect to any disclosed relationships or services that may impact the objectivity and independ- -2- ence of the outside auditor and for recommending that the Board of Directors take appropriate action to ensure the independence of the outside auditor. 4. Membership. Effective June 14, 2001, the Audit Committee shall consist of not less than three (3) members of the Board of Directors. (a) The Audit Committee shall be composed entirely of independent members of the Board of Directors, and no person who is employed by the Company or who is designated as the Chairman of the Board shall be a member of the Audit Committee. No member of the Audit Committee shall have any relationship to the Company or to the Chairman of the Board that may interfere with the exercise of his or her independence from management and the Company. (b) No person may be named to the Audit Committee or shall serve as a member of the Audit Committee who is related by blood or marriage to the Chairman of the Board or to any employee of the Company, who has a business relationship with, or accepts any fees from, the Company (other than as Director), or who is an "affiliated person" of the Company or a member of such other body or board as gives him or her a "cross compensation link," as such terms are defined either by the United States Securities and Exchange Commission (the "SEC") or by the National Association of Securities Dealers, Inc. (the "NASD").

(d) At least one member of the Audit Committee (i) shall have accounting or related financial management expertise, as such qualification is interpreted by the Board of Directors in its business judgment and (ii) upon effectiveness of the SEC's adoption of a definition of the term "financial expert" (the absence of which on the Committee would require disclosure in the Company's periodic reports filed with the SEC), shall meet such definition. (e) In setting the qualifications for the members of the Audit Committee and in electing members to the Audit Committee, the Board of Directors may take into consideration academic background or training in financial analysis or business management, business experience throughout the career of the individual which involved or required financial management analysis and understand- -3- ing, service as a Director and membership on its Audit Committee and such other factors as the Board of Directors may deem appropriate.
