Our Restated Certificate of Incorporation divides or "classifies" our Board of Directors into three classes (Classes I, II and III), with respect to the time for which the directors in each class individually hold office. Each class consists, as nearly as possible, of one-third of the entire Board. Our Board of Directors is currently fixed at eight members. Each director is elected to hold office for a term ending on the date of the third annual meeting following the annual meeting at which such director was elected. The current term for Class I Directors will expire at the 2001 Annual Meeting. Due to the Company's possible merger into a wholly-owned subsidiary of Antigenics Inc., a Delaware corporation, we have no present intentions to hold our 2001 annual meeting. The current terms for Class III and Class II Directors will expire at the 2002 and 2003 Annual Meetings of Stockholders, respectively. DIRECTOR COMPENSATION Non-employee directors receive compensation for each meeting attended and stock option grants when initially elected to the Board and annually thereafter. Each non-employee member of the Board of Directors receives $1,000 for each board meeting attended, $500 for each committee meeting attended and $250 for each telephonic meeting attended, such compensation is paid in the form of cash or common stock at each member's choosing. The directors are also reimbursed for expenses incurred in connection with attending each board and committee meeting. Directors who are not our employees participate in our Amended and Restated 1993 Non-Employee Director Stock Option Plan. Under the Amended and Restated 1993 Non-Employee Director Stock Option Plan, each non-employee director receives (i) a grant of options to purchase 25,000 shares of our common stock upon his or her initial election to the Board and (ii) an annual grant of options to purchase 7,500 shares of our common stock for each year of service as a director, both of which are fully vested upon granting. Directors have a period of two years to exercise their options following their termination of service as a director. The 1993 Non- Employee Director Stock Option Plan also permits discretionary grants of options to non-employee directors who do not serve on the Compensation Committee of the Board of Directors. In 2000, Dr. Lopez-Berestein and Mr. Sutter each received discretionary option grants to purchase 40,000 shares of our common stock. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires our directors and officers, and persons who own more than 10% of our common stock, to file initial reports of ownership and reports of changes in ownership (Forms 3, 4, and 5) of common stock with the Securities and Exchange Commission and The Nasdaq Stock Market. Officers, directors and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all such forms that they file. To the Company's knowledge, based solely on the Company's review of the copies of such reports received by us and on written representations by certain reporting persons that one report on Form 5 was required, we believe that during the fiscal year ended December 31, 2000, all Section 16(a) filing requirements applicable to its officers, directors and 10% stockholders were complied with in a timely manner, with the exception of a late filing reported on Form 5 by Gregory F. Zaic. -3- 6 ITEM 11.

These options may be exercised prior to the end of the seven-year term. The actual value, if any, an executive officer may realize will depend upon the excess of the stock price over the exercise price on the date the option is exercised.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION As required by Nasdaq Stock Market and Securities and Exchange Commission (the "Commission") rules regarding audit committees, the Board of Directors has reviewed the qualifications of its Audit Committee and has determined that none of the current members of the Audit Committee have a relationship with us that might interfere with the exercise of their independence from us or our management. The Compensation Committee makes recommendations concerning compensation, including incentive arrangements, for our officers. The Compensation Committee also administers our Incentive Plans. Mr. Zaic and Drs. Lopez-Berestein and Gardner served as members of the Compensation Committee during 2000. Mr. Zaic serves as chairman of the Compensation Committee. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of our Board of Directors currently consists of Gregory F. Zaic, Phyllis I. Gardner, M.D. and Gabriel Lopez-Berestein, M.D., none of whom are our officers or employees. The Compensation Committee is responsible for evaluating the performance of management, determining the compensation for certain of our executives and administering our Incentive Plans under which grants may be made to our employees. The Committee has furnished the following report on executive compensation for 2000: Under the supervision of the Compensation Committee, we have developed a compensation policy which is designated to attract and retain key executives responsible for our success and motivate management to enhance long-term stockholder value. The annual compensation package for executive officers primarily consists of: o a cash salary which reflects the responsibilities relating to the position and individual performance; o variable performance awards payable in cash or stock and tied to the individual's or our achievement of certain goals or milestones; and o long-term stock-based incentive awards which strengthen the mutuality of interests between the executive officers and our stockholders. In determining the level and composition of compensation of each of our executive officers, the Compensation Committee takes into account various qualitative and quantitative indicators of corporate and individual performance. Although no specific target has been established, the Compensation Committee generally seeks to set salaries comparable to those of peer group companies. In setting such salaries, the Compensation Committee considers its peer group to be certain companies in the biotechnology industries with market capitalizations under $250 million. Such competitive group does not necessarily include the companies comprising the Nasdaq Pharmaceutical Index reflected in the performance graph in this proxy statement, which is the industry -6- 9 categorization we have been placed in by our investment bankers. Because we are still in the development stage, the use of certain traditional performance standards (e.g., profitability and return on equity) is not currently appropriate in evaluating the performance of our executive officers. Consequently, in evaluating the performance of management the Compensation Committee takes into consideration such factors as our achieving specified milestones or goals in our clinical development programs. In addition, the Compensation Committee recognizes performance and achievements that are more difficult to quantify, such as the successful supervision of major corporate projects, demonstrated leadership ability and contributions to the industry. Base compensation is established through our negotiation with the executive officer at the time the executive is hired, and then subsequently adjusted when such officer's base compensation is subject to review or reconsideration. While we have entered into employment agreements with our executive officers, such agreements provide that base salaries after the initial year will be determined by the Compensation Committee after review. When establishing or reviewing base compensation levels for each executive officer, the Compensation Committee, in accordance with its general compensation policy, considers numerous factors, including the responsibilities relating to the position, the qualifications of the executive and the relevant experience the individual brings to us, strategic goals for which the executive has responsibility and compensation levels of companies at a comparable stage of development who compete with us for business, scientific and executive talents. As stated above, such comparable companies are generally those with similar market capitalizations and are not necessarily among the companies comprising the Nasdaq Pharmaceutical Index reflected in the performance graph in this Form 10-K/A. No pre-determined weights are given to any one of such factors. The base salaries for the executive officers generally, and the Chief Executive Officer specifically, for fiscal 2000 were comparable to our peer group companies. In addition to each executive officer's base compensation, the Compensation Committee may award cash bonuses and/or grant awards under our Incentive Plans to chosen executive officers depending on the extent to which certain defined personal and corporate performance goals are achieved. Such corporate performance goals are the same as discussed above. All of our employees, including our executive officers, are eligible to receive long-term stock-based incentive awards under our Incentive Plans as a means of providing such individuals with a continuing proprietary interest in us. Such grants further the mutuality of interest between our employees and our stockholders by providing significant incentives for such employees to achieve and maintain high levels of performance. Our Incentive Plans enhance our ability to attract and retain the services of qualified individuals. Factors considered in determining whether such awards are granted to an executive officer include: o the executive's position in the Company, o his or her performance and responsibilities, o the amount of stock options, if any, currently held by the officer, o the vesting schedules of any such options, and o the executive officer's other compensation. While the Compensation Committee does not adhere to any firmly-established formulas or schedules for the issuance of awards such as options or restricted stock, the Compensation Committee will generally tailor the terms of any such grant to achieve its goal as a long-term incentive award by providing for a vesting schedule encompassing several years or tying the vesting dates to particular corporate or personal milestones. COMPENSATION OF CHIEF EXECUTIVE OFFICER Geoffrey F. Cox, Ph.D. became our Chief Executive Officer in November 1997. His base annual salary was set at $300,000 pursuant to his employment agreement with the us, effective November 3, 1997 (the "Employment -7- 10 Agreement"). His base salary was increased to $310,000 for 2000. In setting the base salary for Dr. Cox, the Committee evaluated the compensation package for chief executive officers of peer group biotechnology companies with similar market capitalizations. The Committee expects that when it reevaluates Dr. Cox's base salary level in the future, it will consider a variety of factors, including Dr. Cox's responsibilities, his general background and qualifications, his achievement of various corporate and personal milestones set by the Committee from time to time, and compensation levels at peer group companies for executives in Dr. Cox's position and with his background. The Committee has not attached any particular relative weighting to the foregoing factors (or any other factors which the Committee may also consider in reaching compensation decisions for our executive officers). The Employment Agreement, as amended, provides that Dr. Cox is eligible to receive future incentive bonus awards in an amount up to 50% of his base annual salary. No bonus was paid to Dr. Cox in 2001 for 2000. The Committee will retain discretion to determine the amount of any future incentive bonus awards to be paid to Dr. Cox, and the Committee expects that it will evaluate a number of factors in reaching this decision, including our strategic goals for which Dr. Cox has responsibility, his other responsibilities, his initiatives and contributions to our achievement of various corporate and strategic goals, and his own achievement of certain personal milestones as determined by the Committee from time to time. The Committee expects that Dr. Cox will participate in the Incentive Plans on the same general terms as other participants in the Plans with respect to future stock option grants that he may be granted from time to time, although the amount of shares underlying option grants to Dr. Cox will be potentially larger than for other employees as a result of his position. In March 2001, Dr. Cox was granted certain performance options to purchase 150,000 shares of our common stock that vest upon the earlier of a change in control of the Company or FDA approval of ATRAGEN(R) for any indication of acute promyelocytic leukemia, but not after September 30, 2001. His Employment Agreement, as amended, also provides that for the next two years, Dr. Cox will be eligible to receive an annual restricted stock grant of 25,000 shares of common stock if certain stock price objectives are achieved during such fiscal years. The Employment Agreement contemplates that these shares will be fully vested on issuance. Section 162(m) of the Internal Revenue Code of 1986 (the "Code"), added by the Revenue Reconciliation Act of 1993, places a $1 million cap on the deductible compensation that can be paid to certain executives of publicly-traded corporations. Amounts that qualify as "performance based" compensation under Section 162(m)(4)(c) of the Code are exempt from the cap and do not count toward the $1 million limit. Generally, stock options will qualify as performance-based compensation. The Compensation Committee has discussed and considered and will continue to evaluate the potential impact of Section 162(m) on us in making compensation determinations, but has not established a set policy with respect to future compensation determinations. The foregoing report is given by the following members of the Compensation Committee: Gregory F. Zaic, Committee Chairman Phyllis I.
