The purpose of the Plan is to provide a means by which employees of Questcor Pharmaceuticals, Inc., a California corporation (the "Company"), and its Affiliates, may be given an opportunity to purchase stock of the Company. The Company, by means of the Plan, seeks to retain the services of its employees, to secure and retain the services of new employees, and to provide incentives for such persons to exert maximum efforts for the success of the Company. Stockholders are requested in this Proposal 2 to approve the Plan. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the meeting will be required to approve the Plan. 4

8 The essential features of the Employee Stock Purchase Plan are outlined below: ADMINISTRATION The Plan shall be administered by the Board of Directors (the "Board") of the Company unless and until the Board delegates administration to a Committee, as provided in the Plan. Whether or not the Board has delegated administration, the Board shall have the final power to determine all questions of policy and expediency that may arise in the administration of the Plan. The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan: (i) To determine when and how rights to purchase stock of the Company shall be granted and the provisions of each offering of such rights (which need not be identical). (ii) To designate from time to time which Affiliates of the Company shall be eligible to participate in the Plan. (iii) To construe and interpret the Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective. (iv) To amend the Plan as provided in paragraph 13. (v) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company and its Affiliates and to carry out the intent that the Plan be treated as an "employee stock purchase plan" within the meaning of Section 423 of the Code. (c) The Board may delegate administration of the Plan to a Committee composed of two (2) or more members of the Board (the "Committee"). If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. SHARES SUBJECT TO THE PLAN Subject to the provisions of paragraph 12 relating to adjustments upon changes in stock, the stock that may be sold pursuant to rights granted under the Plan shall not exceed in the aggregate six hundred thousand (600,000) shares of the Company's common stock (the "Common Stock"). If any right granted under the Plan shall for any reason terminate without having been exercised, the Common Stock not purchased under such right shall again become available for the Plan. GRANT OF RIGHTS; OFFERING The Board or the Committee may from time to time grant or provide for the grant of rights to purchase Common Stock of the Company under the Plan to eligible employees (an "Offering") on a date or dates (the "Offering Date(s)") selected by the Board or the Committee. Each Offering shall be in such form and shall contain such terms and conditions as the Board or the Committee shall deem appropriate, which shall comply with the requirements of Section 423(b)(5) of the Code that all employees granted rights to purchase stock under the Plan shall have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering shall include (through incorporation of the provisions of this Plan by reference in the document comprising the Offering or otherwise) the period during which the Offering shall be effective, which period shall not exceed twenty-seven (27) months beginning with the Offering Date, and the substance of the provisions contained in paragraphs 5 through 8, inclusive. If an employee has more than one right outstanding under the Plan, unless he or she otherwise indicates in agreements or notices delivered hereunder: (1) each agreement or notice delivered by that employee will be deemed to apply to all of his or her rights under the Plan, and (2) a right with a lower exercise price (or an earlier-granted right, if two rights have identical exercise prices), will be exercised to the fullest possible extent before a right with a higher exercise price (or a later-granted right, if two rights have identical exercise prices) will be exercised. 5

9 ELIGIBILITY Rights may be granted only to employees of the Company or, as the Board or the Committee may designate as provided in subparagraph 2(b), to employees of any Affiliate of the Company. Except as provided in subparagraph 5(b), an employee of the Company or any Affiliate shall not be eligible to be granted rights under the Plan, unless, on the Offering Date, such employee has been in the employ of the Company or any Affiliate for such continuous period preceding such grant as the Board or the Committee may require, but in no event shall the required period of continuous employment be equal to or greater than two (2) years. In addition, unless otherwise determined by the Board or the Committee and set forth in the terms of the applicable Offering, no employee of the Company or any Affiliate shall be eligible to be granted rights under the Plan, unless, on the Offering Date, such employee's customary employment with the Company or such Affiliate is for at least twenty (20) hours per week and at least five (5) months per calendar year. The Board or the Committee may provide that each person who, during the course of an Offering, first becomes an eligible employee of the Company or designated Affiliate will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an eligible employee or occurs thereafter, receive a right under that Offering, which right shall thereafter be deemed to be a part of that Offering. Such right shall have the same characteristics as any rights originally granted under that Offering, as described herein, except that: (i) the date on which such right is granted shall be the "Offering Date" of such right for all purposes, including determination of the exercise price of such right; the period of the Offering with respect to such right shall begin on its Offering Date and end coincident with the end of such Offering; and (iii) the Board or the Committee may provide that if such person first becomes an eligible employee within a specified period of time before the end of the Offering, he or she will not receive any right under that Offering. (c) No employee shall be eligible for the grant of any rights under the Plan if, immediately after any such rights are granted, such employee owns stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Affiliate. For purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code shall apply in determining the stock ownership of any employee, and stock which such employee may purchase under all outstanding rights and options shall be treated as stock owned by such employee. (d) An eligible employee may be granted rights under the Plan only if such rights, together with any other rights granted under "employee stock purchase plans" of the Company and any Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such employee's rights to purchase stock of the Company or any Affiliate to accrue at a rate which exceeds twenty-five thousand dollars ($25,000) of fair market value of such stock (determined at the time such rights are granted) for each calendar year in which such rights are outstanding at any time. (e) Officers of the Company and any designated Affiliate shall be eligible to participate in Offerings under the Plan, provided, however, that the Board may provide in an Offering that certain employees who are highly compensated employees within the meaning of Section 423(b)(4)(D) of the Code shall not be eligible to participate. RIGHTS; PURCHASE PRICE On each Offering Date, each eligible employee, pursuant to an Offering made under the Plan, shall be granted the right to purchase up to the number of shares of Common Stock of the Company purchasable with a percentage designated by the Board or the Committee (or fifteen percent (15%) in the absence of any designation) of such employee's Earnings (as defined in subparagraph 7(a)) during the period which begins on the Offering Date (or such later date as the Board or the Committee determines for a particular Offering) and ends on the date stated in the Offering, which date shall be no later than the end of the Offering. The Board or the Committee shall establish one or more dates during an Offering (the "Purchase Date(s)") on which rights granted under the Plan shall be exercised and purchases of Common Stock carried out in accordance with such Offering. In connection with each Offering made under the Plan, the Board or the Committee may specify a maximum number of shares that may be purchased by any employee as well as a maximum aggregate number of shares that may be purchased by all eligible employees pursuant to such Offering. In addition, in connection with each Offering that contains more than one Purchase Date, the Board or the Committee may specify a maximum aggregate number of shares which may be purchased by all eligible employees on any given 6

10 Purchase Date under the Offering. If the aggregate purchase of shares upon exercise of rights granted under the Offering would exceed any such maximum aggregate number, the Board or the Committee shall make a pro rata allocation of the shares available in as nearly a uniform manner as shall be practicable and as it shall deem to be equitable. The purchase price of stock acquired pursuant to rights granted under the Plan shall be not less than the lesser of: (i) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the Offering Date; or (ii) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the Purchase Date. PARTICIPATION; WITHDRAWAL; TERMINATION An eligible employee may become a participant in the Plan pursuant to an Offering by delivering a participation agreement to the Company within the time specified in the Offering, in such form as the Company provides. Each such agreement shall authorize payroll deductions of up to the maximum percentage specified by the Board or the Committee of such employee's Earnings during the Offering. "Earnings" is defined as an employee's regular salary or wages (including amounts thereof elected to be deferred by the employee, that would otherwise have been paid, under any arrangement established by the Company intended to comply with Section 401(k), Section 402(e)(3), Section 125, Section 402(h), or Section 403(b) of the Code, and also including any deferrals under a non-qualified deferred compensation plan or arrangement established by the Company), and may also include or exclude (as provided for each Offering) the following items of compensation: bonuses, commissions, overtime pay, incentive pay, profit sharing, other remuneration paid directly to the employee, the cost of employee benefits paid for by the Company or an Affiliate, education or tuition reimbursements, imputed income arising under any group insurance or benefit program, traveling expenses, business and moving expense reimbursements, income received in connection with stock options, contributions made by the Company or an Affiliate under any employee benefit plan, and similar items of compensation, as determined by the Board or Committee. The payroll deductions made for each participant shall be credited to an account for such participant under the Plan and shall be deposited with the general funds of the Company. A participant may reduce (including to zero) or increase such payroll deductions, and an eligible employee may begin such payroll deductions, after the beginning of any Offering only as provided for in the Offering. A participant may make additional payments into his or her account only if specifically provided for in the Offering and only if the participant has not had the maximum amount withheld during the Offering. At any time during an Offering, a participant may terminate his or her payroll deductions under the Plan and withdraw from the Offering by delivering to the Company a notice of withdrawal in such form as the Company provides. Such withdrawal may be elected at any time prior to the end of the Offering except as provided by the Board or the Committee in the Offering. Upon such withdrawal from the Offering by a participant, the Company shall distribute to such participant all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the participant) under the Offering, without interest, and such participant's interest in that Offering shall be automatically terminated. A participant's withdrawal from an Offering will have no effect upon such participant's eligibility to participate in any other Offerings under the Plan but such participant will be required to deliver a new participation agreement in order to participate in subsequent Offerings under the Plan. Rights granted pursuant to any Offering under the Plan shall terminate immediately upon cessation of a participant's employment with the Company and any designated Affiliate, for any reason, and the Company shall distribute to such terminated employee all of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the terminated employee), under the Offering, without interest. Rights granted under the Plan shall not be transferable by a participant otherwise than by will or the laws of descent and distribution, or by a beneficiary designation as provided in paragraph 14 and, otherwise during his or her lifetime, shall be exercisable only by the person to whom such rights are granted. 7

11 EXERCISE On each Purchase Date specified in the relevant Offering, each participant's accumulated payroll deductions and other additional payments specifically provided for in the Offering (without any increase for interest) will be applied to the purchase of whole shares of stock of the Company, up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares shall be issued upon the exercise of rights granted under the Plan, unless the Offering document specifically provides otherwise. The amount, if any, of accumulated payroll deductions remaining in each participant's account after the purchase of shares which is less than the amount required to purchase one share of stock on the final Purchase Date of an Offering shall be held in each such participant's account for the purchase of shares under the next Offering under the Plan, unless such participant withdraws from such next Offering, as provided in subparagraph 7(b), or is no longer eligible to be granted rights under the Plan, as provided in paragraph 5, in which case such amount shall be distributed to the participant after such final Purchase Date, without interest. The amount, if any, of accumulated payroll deductions remaining in any participant's account after the purchase of shares which is equal to the amount required to purchase whole shares of stock on the final Purchase Date of an Offering shall be distributed in full to the participant after such Purchase Date, without interest. No rights granted under the Plan may be exercised to any extent unless the shares to be issued upon such exercise under the Plan (including rights granted thereunder) are covered by an effective registration statement pursuant to the Securities Act of 1933, as amended (the "Securities Act") and the Plan is in material compliance with all applicable state, foreign and other securities and other laws applicable to the Plan. If on a Purchase Date in any Offering hereunder the Plan is not so registered or in such compliance, no rights granted under the Plan or any Offering shall be exercised on such Purchase Date, and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement and such compliance, except that the Purchase Date shall not be delayed more than twelve (12) months and the Purchase Date shall in no event be more than twenty-seven (27) months from the Offering Date. If on the Purchase Date of any Offering hereunder, as delayed to the maximum extent permissible, the Plan is not registered and in such compliance, no rights granted under the Plan or any Offering shall be exercised and all payroll deductions accumulated during the Offering (reduced to the extent, if any, such deductions have been used to acquire stock) shall be distributed to the participants, without interest. COVENANTS OF THE COMPANY During the terms of the rights granted under the Plan, the Company shall keep available at all times the number of shares of stock required to satisfy such rights. The Company shall seek to obtain from each federal, state, foreign or other regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the rights granted under the Plan. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such rights unless and until such authority is obtained. USE OF PROCEEDS FROM STOCK Proceeds from the sale of stock pursuant to rights granted under the Plan shall constitute general funds of the Company. RIGHTS AS A STOCKHOLDER A participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to rights granted under the Plan unless and until the participant's shares acquired upon exercise of rights hereunder are recorded in the books of the Company. 8

12 ADJUSTMENTS UPON CHANGES IN STOCK If any change is made in the stock subject to the Plan, or subject to any rights granted under the Plan (through merger, consolidation, reorganization, recapitalization, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan and outstanding rights will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan and the class(es) and number of shares and price per share of stock subject to outstanding rights. Such adjustments shall be made by the Board or the Committee, the determination of which shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a "transaction not involving the receipt of consideration by the Company.") In the event of: (1) a dissolution or liquidation of the Company; (2) a merger or consolidation in which the Company is not the surviving corporation; (3) a reverse merger in which the Company is the surviving corporation but the shares of the Company's Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise; or (4) the acquisition by any person, entity or group within the meaning of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") or any comparable successor provisions (excluding any employee benefit plan, or related trust, sponsored or maintained by the Company or any Affiliate of the Company) of the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable successor rule) of securities of the Company representing at least fifty percent (50%) of the combined voting power entitled to vote in the election of directors, then, as determined by the Board in its sole discretion (i) any surviving or acquiring corporation may assume outstanding rights or substitute similar rights for those under the Plan, (ii) such rights may continue in full force and effect, or (iii) participants' accumulated payroll deductions may be used to purchase Common Stock immediately prior to the transaction described above and the participants' rights under the ongoing Offering terminated. AMENDMENT OF THE PLAN The Board at any time, and from time to time, may amend the Plan. However, except as provided in paragraph 12 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the stockholders of the Company within twelve (12) months before or after the adoption of the amendment if such amendment requires stockholder approval in order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code or to comply with the requirements of Rule 16b-3 promulgated under the Exchange Act or any Nasdaq or securities exchange requirements. The Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to employee stock purchase plans and/or to bring the Plan and/or rights granted under it into compliance therewith. Rights and obligations under any rights granted before amendment of the Plan shall not be altered or impaired by any amendment of the Plan, except with the consent of the person to whom such rights were granted, or except as necessary to comply with any laws or governmental regulations, or except as necessary to ensure that the Plan and/or rights granted under the Plan comply with the requirements of Section 423 of the Code. DESIGNATION OF BENEFICIARY A participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant's account under the Plan in the event of such participant's death subsequent to the end of an Offering but prior to delivery to the participant of such shares and cash. In addition, a participant may file 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 during an Offering. 9

13 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 sole 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. TERMINATION OR SUSPENSION OF THE PLAN The Board in its discretion, may suspend or terminate the Plan at any time. No rights may be granted under the Plan while the Plan is suspended or after it is terminated. Rights and obligations under any rights granted while the Plan is in effect shall not be altered or impaired by suspension or termination of the Plan, except as expressly provided in the Plan or with the consent of the person to whom such rights were granted, or except as necessary to comply with any laws or governmental regulation, or except as necessary to ensure that the Plan and/or rights granted under the Plan comply with the requirements of Section 423 of the Code. EFFECTIVE DATE OF PLAN The Plan shall become effective as determined by the Board, but no rights granted under the Plan shall be exercised unless and until the Plan has been approved by the stockholders of the Company within twelve (12) months before or after the date the Plan is adopted by the Board. THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 2. PROPOSAL 3 RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS The Board of Directors has selected Ernst & Young LLP as the Company's independent auditors for the fiscal year ending December 31, 2000, and has further directed that management submit the selection of independent auditors for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has audited the Company's financial statements since its inception in 1992. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. Stockholder ratification of the selection of Ernst & Young LLP as the Company's independent auditors is not required by the Company's Bylaws or otherwise. However, the Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee and the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee and the Board in their discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting will be required to ratify the selection of Ernst & Young LLP. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved. THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 3. 10

Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file. To the Company's knowledge, based solely on a review of the copies of such reports furnished to the Company and written representations that no other reports were required, during the five months ended December 31, 1999 and the fiscal year ended July 31, 1999. All Section 16(a) filing requirements applicable to its officers, directors and greater than ten percent beneficial owners were complied with. COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS COMPENSATION OF DIRECTORS The Company compensates its non-employee directors for their service on the Board with an initial grant of 25,000 options under the 1993 Non-Employee Equity Incentive Plan and an annual grant of 10,000 stock options under the Plan upon reappointment by the shareholders as a director. Options granted under the 1993 Plan have an exercise price equal to 85% of the fair market value of the Company's Common Stock on the date of the grant and vest in 48 equal monthly installments commencing on the date of the grant, provided the non-employee director serves continuously on the Board during the month. Through November 1999, the Company paid a bonus award of $2,000 in common stock to non-employee directors for each Board of Director meeting attended. The number of shares of common stock issued with each bonus is equal to $2,000 divided by the ten-day average of the closing sales price for the common stock as quoted on the American Stock Exchange, Inc. for the ten trading days immediately preceding the date of the board meeting at which the bonus is earned. The stock bonuses are 100% vested on the date of the grant. For the five months ended December 31, 1999, the total value of compensation paid to non-employee directors was $54,000. In December 1999, the Company paid each non-employee director a per meeting fee of $2,000. For the five months ended December 31, 1999, meeting fees totaled $12,000. The Company also reimburses its directors who are not employees for their reasonable expenses incurred in attending meetings. No additional fees are paid for participation in committee meetings. Directors who are officers of the Company receive no additional compensation for Board service. 12

(2) Based on options to purchase 456,050 shares of Common Stock granted to employees in fiscal 1999. (3) The potential realizable value is calculated based on the term of the option at the time of grant (ten years). Stock price appreciation of five percent and ten percent is assumed pursuant to rules promulgated by the Securities and Exchange Commission and does not represent the Company's prediction of the stock price performance. The potential realizable value is calculated by assuming that the fair value of the Common Stock at the date of the grant, as determined by the Board of Directors, appreciates at the indicated rate for the entire term of the option and that the option is exercised at the exercise price and sold on the last day of its term at the appreciated price. In the five months ended December 31, 1999 and the fiscal year ended July 31, 1999, no options for shares of Common Stock were exercised by Mr. Casamento, Mr. Marangos, Dr. Dziewanowska, Mr. Nassif and Dr. Sullivan pursuant to purchase rights granted under the 1992 Stock Plan. 14

19 REPORT OF THE COMPENSATION AND STOCK OPTION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION RESPONSIBILITIES AND COMPOSITION OF THE COMMITTEE The Compensation Committee (the "Committee") of the Company's Board of Directors (the "Board") is responsible for (i) recommending the type and level of compensation for directors, officers and employees of the Company, and (ii) administering the Company's equity incentive Equity Incentive Plans. The Committee is also responsible for reviewing the performance of the Company's executive officers. Compensation for directors, officers and employees of the Company are approved by the Board. The Committee is composed of three members of the Board: Roger G. Stoll, Frank J. Sasinowski and Robert F. Allnutt. Messrs. Stoll, Sasinowski and Allnutt have never served as employees of the Company or its subsidiaries. This report describes the philosophy that underlies the components of the Company's executive compensation programs. It also describes the details of the key elements of such programs, as well as the rationale for compensation paid to the Company's Chief Executive Officer and its officers in general. COMPENSATION PHILOSOPHY AND OBJECTIVES The Committee believes that all officers and employees should be compensated based on their contribution to the Company and to building sustainable long-term value for the Company's stockholders. In determining specific compensation programs, the Committee considers individual and group performance, including successful achievement of business, management and research objectives, and maintenance of strong relationships with the firm's collaborators. The Committee strives to design compensation programs that will tie individual rewards to the Company's success and align interests between officers, employees and stockholders of the Company. The Committee also strives to design compensation programs that help retain its officers and employees and encourage personal and professional development and growth. Compensation Of Officers Generally Officer compensation programs typically consist of four components: base salaries, bonuses, equity incentives and other compensation. Base salaries are established on the basis of the officer's experience, salary history and contribution to the Company. Bonuses are established on the basis of individual achievement of established objectives and overall corporate performance. Equity incentives typically consist of stock purchases and stock option grants under the Company's equity incentive Plans. Stock options are granted as inducements to employment with the Company, to aid in retention and to align the interest of such officers with those of the Company's stockholders. Other compensatory components typically consist of loans granted to officers in connection with purchases of shares of the Company's common stock under the Company's equity incentive Plans, relocation expenses, insurance premiums and similar payments. All components are evaluated annually to ensure that such components are appropriate and consistent with the strategic business objectives of the Company, corporate culture, and with enhancing stockholder value. Base Salary Base salaries for the Company's officers are established at competitive levels according to the salaries attributable to comparable positions at comparable companies within the healthcare, management consulting and information services industries. The Committee reviews the base salary of each officer annually. The Committee considers each officer's level of responsibility, experience and overall contribution to the Company. The Committee also considers equity and fairness in setting the base salary of its officers. In making salary recommendations, the Committee exercises discretion based on the foregoing criteria. The Committee does not apply a specific formula to determine the weight of each factor considered. 16

20 Bonuses Bonuses for the Company's officers are determined based on the attainment of specific business, management and research objectives. These objectives vary depending upon the position or role of the individual officer. The Committee also considers each officer's contribution to the Company's financial performance and organizational growth. The Board establishes specific objectives for each officer the beginning of each year. Stock Options and Other Equity Incentives The Committee administers the following equity incentive Plans for the Company: (i) the 1992 Stock Option Plan, and (ii) the 1993 Non-Employee Directors Stock Option Plan (collectively, the "Plans"). The Company's officers can receive stock option grants and other equity-based incentives under the Stock Option Plan. The Company's officers may also receive non-statutory stock option grants that are not pursuant to any of the Company's Plans. Options to purchase shares of the Company's Common Stock are granted as incentives to the Company's officers, to aid in the retention of such officers and to align the interests of such officers with those of the stockholders. The Committee grants incentive stock options to officers and employees of the Company. Options granted during the five months ended December 31, 1999 and the fiscal year ended July 31, 1999, were granted at a price equal to 100% of the fair market value of the Company's common stock on the date of grant. POLICY ON DEDUCTIBILITY OF COMPENSATION Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), provides in general that companies may not deduct in any taxable year compensation in excess of $1,000,000 paid to any Named Executive Officer, except to the extent such excess constitutes performance-based compensation. In order for incentive compensation to qualify as performance based compensation under Section 162(m), the Company's discretion to grant awards must be strictly limited. The Company does not currently intend to qualify its incentive compensation Equity Incentive Plans under Section 162(m). The policy of the Company is to qualify future compensation arrangements to ensure deductibility, except in those cases where stockholder value is maximized by an alternative approach. CHIEF EXECUTIVE OFFICER COMPENSATION After November 1999, prior to January 1, 2000, Mr. Casamento's base salary was not less than $341,250 and after January 1, 2000, not less than $375,000. Mr. Casamento has the opportunity to receive an additional annual bonus for each fiscal year of the Company in an amount up to 50% of Mr. Casamento's base salary. Additionally, during 1999, Mr. Casamento was granted an option to purchase 1,068,549 shares of common stock. In determining Mr. Casamento's 1999 salary, the Committee took into account (i) Mr. Casamento's recent performance as CEO of RiboGene Inc., (ii) the scope of Mr. Casamento's responsibilities, and (iii) the Board's confidence in Mr. Casamento to lead the Company's continued development. The foregoing report has been approved by all of the members of the Committee. THE COMPENSATION COMMITTEE Roger G. Stoll, Ph.D., Chairman Frank J. Sasinowski Robert I. Allnutt 17
