All stockholders are cordially invited to attend the meeting in person. However, to assure your representation at the meeting, you are urged to mark, sign, date and return the enclosed Proxy card as promptly as possible in the prepaid-postage envelope enclosed for that purpose. Stockholders attending the meeting may vote in person even if they have returned a Proxy. By Order of the Board of Directors, Margaret Valeur-Jensen Secretary San Diego, California April 23, 1999

NEUROCRINE BIOSCIENCES, INC. PROXY STATEMENT INFORMATION CONCERNING SOLICITATION AND VOTING GENERAL The enclosed Proxy is solicited on behalf of Neurocrine Biosciences, Inc., a Delaware corporation (the "Company"), for use at its 1999 Annual Meeting of Stockholders to be held on May 21, 1999, at 8:30 a.m., local time, or at any adjournments or postponements thereof, for the purposes set forth in this Proxy Statement and in the accompanying Notice of Annual Meeting of Stockholders. The Annual Meeting will be held at the Company's corporate headquarters, located at 10555 Science Center Drive, San Diego, California 92121. The Company's telephone number is (619) 658-7600. These proxy solicitation materials were mailed on or about April 28, 1999 to all stockholders entitled to vote at the meeting. RECORD DATE; OUTSTANDING SHARES Stockholders of record at the close of business on April 15, 1999 (the "Record Date"), are entitled to receive notice of and vote at the meeting. On the Record Date, 18,960,581 shares of the Company's Common Stock, $0.001 par value, were issued and outstanding. The Company has approximately 4,900 shareholders, of which approximately 216 are shareholders of record. For information regarding holders of more than five percent of the outstanding Common Stock, see "Stock Ownership of Principal Stockholders and Management" below. REVOCABILITY OF PROXIES Proxies given pursuant to this solicitation may be revoked at any time before they have been used. Revocation will occur by delivering a written notice of revocation to the Company or by duly executing a proxy bearing a later date. Revocation will also occur if the person attends the meeting and votes in person. VOTING AND SOLICITATION Every stockholder of record on the Record Date is entitled, for each share held, to one vote on each proposal or item that comes before the meeting. In the election of Directors, each stockholder will be entitled to vote for two nominees and the two nominees with the greatest number of votes will be elected. The cost of this solicitation will be borne by the Company. The Company may reimburse expenses incurred by brokerage firms and other persons representing beneficial owners of shares in forwarding solicitation material to beneficial owners. Proxies may be solicited by certain of the Company's Directors, officers and regular employees, without additional compensation, personally, by telephone or by telegram. QUORUM; ABSTENTIONS; BROKER NON-VOTES Votes cast by proxy or in person at the Annual Meeting will be tabulated by the Inspector of Elections (the "Inspector") with the assistance of the Company's Transfer Agent. The Inspector will also determine whether or not a quorum is present. Except in certain specific circumstances, the affirmative vote of a majority of shares present in person or represented by proxy at a duly held meeting at which a quorum is present is required under Delaware law for approval of proposals presented to stockholders. In general, Delaware law also provides that a quorum consists of a majority of shares entitled to vote and present or represented by proxy at the meeting. The Inspector will treat shares that are voted "WITHHELD" or "ABSTAIN" as being present and entitled to vote for purposes of determining the presence of a quorum but will not be treated as votes in favor of approving any matter submitted to the stockholders for a vote. Any proxy which is returned using the form of proxy enclosed and which is not marked as to a particular item will be voted for the election of the Directors named in the proxy, for the approval of the amendment of the 1992 Incentive Stock Plan, for the confirmation of the appointment of the designated independent auditors and, as the proxy holders deem advisable, on other matters that may come before the meeting, as the case may be with respect to the items not marked. If a broker indicates on the enclosed proxy or its substitute that it does not have discretionary authority as to certain shares to vote on a particular matter ("Broker Non-Votes"), those shares will be considered as present with respect to that matter. The Company believes that the tabulation procedures to be followed by the Inspector are consistent with the general statutory requirements in Delaware concerning voting of shares and determination of a quorum. DEADLINE FOR RECEIPT OF STOCKHOLDER PROPOSALS Stockholder proposals which are intended to be presented at the Company's 2000 Annual Meeting must be received by the Company no later than December 30, 1999 in order that they may be included in the proxy statement and form of proxy for that meeting. SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, as amended, (the "Exchange Act") requires the Company's officers and Directors, and persons who own more than ten percent of a registered class of the Company's equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or Form 5 with the SEC. Such officers, Directors and 10% stockholders are also required by SEC rules to furnish the Company with copies of all Section 16(a) forms they file. Based solely on its review of the copies of such forms received by it, or written representations from certain reporting persons, the Company believes that, during the fiscal year ended December 31, 1998, all Section 16(a) filing requirements applicable to its officers, Directors and 10% stockholders were complied with.

PROPOSAL ONE: ELECTION OF DIRECTORS GENERAL The Company's Bylaws provide that the Board of Directors is composed of seven (7) Directors. The Company's Certificate of Incorporation provides that the Board of Directors is divided into three classes. As of December 31, 1998, there were two Directors in Class I (Wylie W. Vale and Joseph A. Mollica), two Directors in Class II (David E. Robinson and Richard F. Pops), and two Directors in Class III (Gary A. Lyons and Harry F. Hixson, Jr.). Errol DeSouza served as a Class I Director until his resignation from the Company on August 31, 1998. This vacancy has not been filled. David E. Robinson resigned from the Board of Directors on March 2, 1999. This vacancy was filled on April 22, 1999, with the appointment of Stephen A. Sherwin as a Class II Director. The Directors in Class III hold office until the 1999 Annual Meeting of Stockholders, the Directors in Class I hold office until the 2000 Annual Meeting of Stockholders and the Directors in Class II hold office until the 2001 Annual Meeting of Stockholders (or, in each case, until their earlier resignation, removal from office or death). After each such election, the Directors in each such case will then serve in succeeding terms of three years and until their successors are duly elected and qualified. Officers of the Company serve at the discretion of the Board of Directors. There are no family relationships among the Company's Directors and executive officers. The term of office of Directors Gary A. Lyons and Harry F. Hixson, Jr. expire at the 1999 Annual Meeting. At the 1999 Annual Meeting, the stockholders will elect two Class III Directors for a term of three years. VOTE REQUIRED The two nominees receiving the highest number of affirmative votes of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote on the election of Directors shall be elected to the Board of Directors. Votes withheld from any Director are counted for purposes of determining the presence or absence of a quorum, but have no legal effect under Delaware law. While there is no definitive statutory or case law authority in Delaware as to the proper treatment of abstentions and broker non-votes in the election of Directors, the Company believes that both abstentions and broker non-votes should be counted for purposes of whether a quorum is present at the Annual Meeting. In the absence of precedent to the contrary, the Company intends to treat abstentions and broker non-votes with respect to the election of Directors in this manner. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the Company's two nominees named below. If any nominee of the Company is unable or declines to serve as a Director at the time of the Annual Meeting, the proxies will be voted for any nominee who is designated by the present Board of Directors to fill the vacancy. It is not expected that any nominee will be unable or will decline to serve as a Director. The Board of Directors recommends that stockholders vote "FOR" the nominees listed below.

BOARD MEETINGS AND COMMITTEES The Board of Directors of the Company held a total of 6 meetings and took action by written consent on 3 occasions during 1998. During 1998, the Board of Directors had an Audit Committee and a Compensation Committee. No Director attended fewer than 75% of the aggregate of the total number of meetings of the Board of Directors and the total number of meetings held by all committees of the Board of Directors on which he served. The Audit Committee in 1998 consisted of Directors Richard F. Pops, Harry F. Hixson, Jr. and Wylie W. Vale and met once during 1998. This committee is primarily responsible for approving the services performed by the Company's independent auditors and for reviewing and evaluating the Company's accounting principles and its system of internal accounting controls. The Compensation Committee in 1998 consisted of Directors Joseph A. Mollica, David E. Robinson and Harry F. Hixson, Jr. This committee met twice and took action by written consent once during 1998. The Compensation Committee reviewed and recommended to the Board the compensation of executive officers and other employees of the Company. BOARD COMPENSATION Non-employee Directors are reimbursed for expenses incurred in connection with performing their respective duties as Directors of the Company. The Company did not pay cash compensation to any Director prior to February 1997. Directors, who are not employees or consultants of the Company, receive $1,750 for each regular meeting of the Board of Directors (the Chairman of the Board receives $2,500), $750 for each special meeting, $600 for each committee meeting and $600 for each telephone meeting lasting more than one hour, which such Director attends. Each non-employee Director participates in the 1996 Director Stock Option Plan (the "Director Plan"). Options granted under the Director Plan are automatic and non-discretionary and have a term of ten years. The Director Plan provides for the grant of nonstatutory options to purchase 10,000 shares of the Company's Common Stock to each non-employee Director at each annual meeting of the stockholders commencing in 1997, provided that such non-employee Director has been a non-employee Director of the Company for at least six months prior to the date of such annual meeting of the stockholders. Each new non-employee Director is automatically granted nonstatutory stock options to purchase 10,000 shares of the Company's Common Stock upon the date such person joins the Board of Directors. In addition to the options granted under the Director Plan, the Company has agreed to grant Dr. Mollica, as Chairman of the Board, an option to purchase an additional 5,000 shares at each annual meeting of the stockholders commencing in 1999. All options granted to non-employee Directors shall vest over the three-year period following the date of grant and shall be exercisable at the fair market value of the Company's Common Stock on the date of the grant. PROPOSAL TWO: APPROVAL OF AMENDMENT OF THE 1992 INCENTIVE STOCK PLAN INCREASE OF 600,000 SHARES The Company's 1992 Incentive Stock Plan, as amended (the "Plan") was approved by the Board of Directors and the stockholders of the Company in 1992. Currently there are a total of 4,700,000 shares of Common Stock reserved for issuance under the Plan. In March 1999, the Board of Directors approved a further increase of 600,000 shares issuable under the Plan, which, if approved by the stockholders, would increase the total shares reserved for issuance under the Plan to 5,300,000 shares. The Board believes the proposed increase in the number of shares reserved for issuance under the Plan is in the best interests of the Company. In particular, the Board has determined that the proposed increase will provide an additional reserve of shares for issuance under the Plan and thus enable the Company to attract and retain valuable employees. As of April 15, 1999, there were options outstanding to purchase 3,026,540 shares of Common Stock pursuant to the 1992 Stock Plan; 148,451 shares remained available for future option grants subject to stockholder approval; and 1,525,009 options were exercised and are now outstanding shares of Common Stock. SUMMARY OF THE PLAN The essential features of the Plan, as amended and restated, are summarized below. This summary does not purport to be complete and is subject to, and qualified by, reference to all provisions of the Plan, as amended and restated. General. The purpose of the Plan is to attract and retain the best available personnel, to provide additional incentive to the employees and consultants of the Company and to promote the success of the Company's business. Options and stock purchase rights may be granted under the Plan. Options granted under the Plan may be either "incentive stock options," as defined in Section 422 of the Internal Revenue Code (the "Code"), or nonstatutory stock options. Administration. The Plan may generally be administered by the Board or a Committee appointed by the Board. The administrators of the Plan are referred to herein as the "Administrator." The Administrator may make any determinations deemed necessary or advisable for the Plan. Eligibility. Nonstatutory stock options and stock purchase rights may be granted under the Plan to employees and consultants (including Directors) of the Company and any parent or subsidiary of the Company. Incentive stock options may be granted only to employees. The Administrator, in its discretion, selects the employees and consultants to whom options and stock purchase rights may be granted, the time or times at which such options and stock purchase rights shall be granted, and the number of shares subject to each such grant. Limitations. Section 162(m) of the Code places limits on the deductibility for federal income tax purposes of compensation paid to certain executive officers of the Company. In order to preserve the Company's ability to deduct the compensation income associated with options and stock purchase rights granted to such persons, the Plan provides that no employee may be granted, in any fiscal year of the Company, options and stock purchase rights to purchase more than 250,000 shares of Common Stock. Notwithstanding this limit, however, in connection with an employee's initial employment, he or she may be granted options or stock purchase rights to purchase up to an additional 250,000 shares of Common Stock. Terms and Conditions of Options. Each option is evidenced by a stock option agreement between the Company and the optionee, and is subject to the following additional terms and conditions: (a) Exercise Price. The Administrator determines the exercise price of options at the time the options are granted. The exercise price of an incentive stock option may not be less than 100% of the fair market value of the Common Stock on the date such option is granted; provided, however, the exercise price of an incentive stock option granted to a 10% shareholder may not be less than 110% of the fair market value of the Common Stock on the date such option is granted. The exercise price of a nonstatutory stock option may not be less than 85% of the fair market value of the Common Stock on the date such option is granted; provided, however, the exercise price of a nonstatutory stock option granted to a 10% shareholder may not be less than 110% of the fair market value of the Common Stock on the date such option is granted. The fair market value of the Common Stock is generally determined with reference to the closing sale price for the Common Stock (or the closing bid if no sales were reported) on the last market trading day prior to the date the option is granted. (b) Exercise of Option; Form of Consideration. The Administrator determines when options become exercisable and may, in its discretion, accelerate the vesting of any outstanding option. The means of payment for shares issued upon exercise of an option is specified in each option agreement. The Plan permits payment to be made by cash, check, promissory note, other shares of Common Stock of the Company (with some restrictions), cashless exercise, any other form of consideration permitted by applicable law, or any combination thereof. (c) Term of Option. The term of option may be no more than ten (10) years from the date of grant; provided that in the case of an incentive stock option granted to a 10% shareholder, the term of the option may be no more than five (5) years from the date of grant. No option may be exercised after the expiration of its term. (d) Termination of Employment. If an optionee's employment or consulting relationship terminates for any reason (other than death or disability), then all options held by the optionee under the Plan expire on the earlier of (i) the date set forth in his or her notice of grant (which date is typically 30 days after the date of such termination), or (ii) the expiration date of such option. To the extent the option is exercisable at the time of the optionee's termination, the optionee may exercise all or part of his or her option at any time before it terminates. (e) Disability. If an optionee's employment or consulting relationship terminates as a result of disability, then all options held by such optionee under the Plan expire on the earlier of (i) 6 months from the date of such termination (or such longer period of time not exceeding 12 months as determined by the Administrator) or (ii) the expiration date of such option. The optionee (or the optionee's estate or a person who has acquired the right to exercise the option by bequest or inheritance), may exercise all or part of the option at any time before such expiration to the extent that the option was exercisable at the time of such termination. (f) Death. In the event of an optionee's death: (i) during the optionee's employment or consulting relationship with the Company, the option may be exercised, at any time within 6 months of the date of death (but no later than the expiration date of such option) by the optionee's estate or a person who has acquired the right to exercise the option by bequest or inheritance, but only to the extent that the optionee's right to exercise the option would have accrued if he or she had remained an employee or consultant of the Company 6 months after the date of death; or (ii) within 30 days (or such other period of time not exceeding 3 months as determined by the Administrator) after the optionee's employment or consulting relationship with the Company terminates, the option may be exercised at anytime within 6 months (or such other period of time as determined by the Administrator) following the date of death (but in no event later than the expiration date of the option) by the optionee's estate or a person who has acquired the right to exercise the option by bequest or inheritance, but only to the extent of the optionee's right to exercise the option at the date of termination. (g) Nontransferability of Options: Unless otherwise determined by the Administrator, options granted under the Plan are not transferable other than by will or the laws of descent and distribution, and may be exercisable during the optionee's lifetime only by the optionee. (h) Other Provisions: The stock option agreement may contain other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator. Stock Purchase Rights. A stock purchase right gives the purchaser a period of no longer than 6 months from the date of grant to purchase Common Stock. The purchase price of Common Stock purchased pursuant to a stock purchase right is determined in the same manner as for nonstatutory stock options. A stock purchase right is accepted by the execution of a restricted stock purchase agreement between the Company and the purchaser, accompanied by the payment of the purchase price for the shares. Unless the Administrator determines otherwise, the restricted stock purchase agreement shall give the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser's employment or consulting relationship with the Company for any reason (including death and disability). The purchase price for any shares repurchased by the Company shall be the original price paid by the purchaser. The repurchase option lapses at a rate determined by the Administrator. A stock purchase right is nontransferable other than by will or the laws of descent and distribution, and may be exercisable during the optionee's lifetime only by the optionee. Adjustments Upon Changes in Capitalization. In the event that the stock of the Company changes by reason of any stock split, reverse stock split, stock dividend, combination, reclassification or other similar change in the capital structure of the Company effected without the receipt of consideration, appropriate adjustments shall be made in the number and class of shares of stock subject to the Plan, the number and class of shares of stock subject to any option or stock purchase right outstanding under the Plan, and the exercise price of any such outstanding option or stock purchase right. In the event of a liquidation or dissolution, any unexercised options or stock purchase rights will terminate. The Administrator shall notify the optionee fifteen (15) days prior to the consummation of the liquidation or dissolution. In connection with any merger, consolidation, acquisition of assets or like occurrence involving the Company, each outstanding option or stock purchase right may be assumed or an equivalent option or right may be substituted by the successor corporation. The vesting of each outstanding option or stock purchase right shall accelerate (i.e. become exercisable immediately in full) in any of the following events: (1) if the successor corporation refuses to assume the option or stock purchase rights, or to substitute substantially equivalent options or rights, (2) if the employment of the optionee is involuntarily terminated without cause within one year following the date of closing of the merger or acquisition, or (3) if the merger or acquisition is not approved by the members of the board of directors in office prior to the commencement of such merger or acquisition. Amendment and Termination of the Plan. The Board may amend, alter, suspend or terminate the Plan, or any part thereof, at any time and for any reason. However, the Company shall obtain shareholder approval for any amendment to the Plan to the extent necessary to comply with applicable laws, rules and regulations. No such action by the Board or shareholders may alter or impair any option or stock purchase right previously granted under the Plan without the consent of the optionee. Unless terminated earlier, the Plan shall terminate ten years from the date of its approval by the shareholders or the Board of the Company, whichever is earlier. FEDERAL INCOME TAX CONSEQUENCES Incentive Stock Options. An optionee who is granted an incentive stock option does not recognize taxable income at the time the option is granted or upon its exercise, although the exercise is an adjustment item for alternative minimum tax purposes and may subject the optionee to the alternative minimum tax. Upon a disposition of the shares more than two years after grant of the option and one year after exercise of the option, any gain or loss is treated as long-term capital gain or loss. Net capital gains on shares held one year or less may be taxed at a maximum federal rate of 28%, while net capital gains on shares held for more than one year may be taxed at a maximum federal rate of 20%. Capital losses are allowed in full against capital gains and up to $3,000 against other income. If these holding periods are not satisfied, the optionee recognizes ordinary income at the time of disposition equal to the difference between the exercise price and the lower of (i) the fair market value of the shares at the date of the option exercise or (ii) the sale price of the shares. Any gain or loss recognized on such a premature disposition of the shares in excess of the amount treated as ordinary income is treated as long-term or short-term capital gain or loss, depending on the holding period. A different rule for measuring ordinary income upon such a premature disposition may apply if the optionee is also an officer, Director, or 10% shareholder of the Company. Unless limited by Section 162(m) of the Code, the Company is entitled to a deduction in the same amount as the ordinary income recognized by the optionee. Nonstatutory Stock Options. An optionee does not recognize any taxable income at the time he or she is granted a nonstatutory stock option. Upon exercise, the optionee recognizes taxable income generally measured by the excess of the then fair market value of the shares over the exercise price. Any taxable income recognized in connection with an option exercise by an employee of the Company is subject to tax withholding by the Company. Unless limited by Section 162(m) of the Code, the Company is entitled to a deduction in the same amount as the ordinary income recognized by the optionee. Upon a disposition of such shares by the optionee, any difference between the sale price and the optionee's exercise price, to the extent not recognized as taxable income as provided above, is treated as long-term or short-term capital gain or loss, depending on the holding period. Net capital gains on shares held one year or less may be taxed at a maximum federal rate of 28%, while net capital gains on shares held for more than one year may be taxed at a maximum federal rate of 20%. Capital losses are allowed in full against capital gains and up to $3,000 against other income. Stock Purchase Rights. Stock purchase rights will generally be taxed in the same manner as nonstatutory stock options. However, restricted stock is generally purchased upon the exercise of a stock purchase right. At the time of purchase, restricted stock is subject to a "substantial risk of forfeiture" within the meaning of Section 83 of the Code, because the Company may repurchase the stock when the purchaser ceases to provide services to the Company. As a result of this substantial risk of forfeiture, the purchaser will not recognize ordinary income at the time of purchase. Instead, the purchaser will recognize ordinary income on the dates when the stock is no longer subject to a substantial risk of forfeiture (i.e., when the Company's right of repurchase lapses). The purchaser's ordinary income is measured as the difference between the purchase price and the fair market value of the stock on the date the stock is no longer subject to right of repurchase. The purchaser may accelerate to the date of purchase his or her recognition of ordinary income, if any, and begin his or her capital gains holding period by timely filing, (i.e., within thirty days of the purchase), an election pursuant to Section 83(b) of the Code. In such event, the ordinary income recognized, if any, is measured as the difference between the purchase price and the fair market value of the stock on the date of purchase, and the capital gain holding period commences on such date. The ordinary income recognized by a purchaser who is an employee will be subject to tax withholding by the Company. Different rules may apply if the purchaser is also an officer, Director, or 10% shareholder of the Company. The foregoing is only a summary of the effect of federal income taxation upon optionees, holders of stock purchase rights, and the Company with respect to the grant and exercise of options and stock purchase rights under the Plan. It does not purport to be complete, and does not discuss the tax consequences of the employee's or consultant's death or the provisions of the income tax laws of any municipality, state or foreign country in which the employee or consultant may reside. VOTE REQUIRED At the Annual Meeting, the shareholders are being asked to approve the amendment of the 1992 Incentive Stock Plan to increase the number of shares reserved for issuance thereunder. The affirmative vote of the holders of a majority of the shares casting their votes at the Annual Meeting will be required to approve the amendment of the 1992 Incentive Plan. The Board of Directors recommends voting "FOR" the amendment of the 1992 Incentive Stock Plan. PROPOSAL THREE: RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS The Board of Directors has selected Ernst & Young LLP ("Ernst & Young"), to audit the financial statements of the Company for the current fiscal year ending December 31, 1999. Ernst & Young has audited the Company's financial statements since 1992. Representatives of Ernst & Young are expected to be present at the meeting, will have the opportunity to make a statement if they so desire, and are expected to be available to respond to appropriate questions. The affirmative vote of the holders of a majority of the shares represented and voting at the meeting will be required to approve and ratify the Board's selection of Ernst & Young. The Board of Directors recommends voting "FOR" approval and ratification of such selection. In the event of a negative vote on such ratification, the Board of Directors will reconsider its selection.

Options granted to Dr. Valeur-Jensen become exercisable as to 1/4th of the option shares on December 31, 1999 and 1/48th per month thereafter. All options shown granted in 1998 to Messrs.

The fair market value of options granted to Dr. Valeur-Jensen on October 1, 1998 was $5.625. The exercise price may be paid in cash, promissory note, by delivery of already owned shares subject to certain conditions, or pursuant to a cashless exercise procedure under which the optionee provides irrevocable instructions to a brokerage firm to sell the purchased shares and remit to the Company, out of sale proceeds, an amount equal to the exercise price plus all applicable withholding taxes. (2) Potential realizable value is based on the assumption that the Common Stock of the Company appreciates at the annual rate shown (compounded annually) from the date of the grant until the expiration of the ten-year option term. These numbers are calculated based on the requirements promulgated by the Securities and Exchange Commission and do not reflect the Company's estimate of future stock price growth.

REPORT OF THE COMPENSATION COMMITTEE The following is a report of the Compensation Committee of the Company describing the compensation policies and rationale applicable to the Company's executive officers with respect to the compensation paid to such executive officers for the year ended December 31, 1998. The information contained in this report shall not be deemed to be "soliciting material" or to be "filed" with the Securities and Exchange Commission nor shall such information be incorporated by reference into any future filing under the Securities Act or the Exchange Act, except to the extent that the Company specifically incorporates it by reference into any such filing. The Compensation Committee (the "Committee") of the Board of Directors reviews and recommends to the Board of Directors for approval the Company's executive compensation policies. The Committee is responsible for reviewing the salary and benefits structure of the Company at least annually to insure its competitiveness within the Company's industry. The following is the report of the Committee describing the compensation policies and rationales applicable to the Company's executive officers with respect to the compensation paid to such executive officers for the fiscal year ended December 31, 1998. In 1998, the members of the Committee were David E. Robinson, and Harry F. Hixson, Jr. David Robinson resigned as a member of the Company's Board of Directors and the Compensation Committee as of March 2, 1999. COMPENSATION PHILOSOPHY The Company's philosophy in establishing its compensation policy for executive officers and other employees is to create a structure designed to attract and retain highly skilled individuals by establishing salaries, benefits, and incentive compensation which compare favorably with those for similar positions in other biotechnology companies. Compensation for the Company's executive officers consists of a base salary and potential incentive cash bonuses, as well as potential incentive compensation through stock options and stock ownership. BASE SALARY The base salary component of compensation is designed to compensate executive officers competitively at levels necessary to attract and retain qualified executives in the pharmaceutical and biotechnology industry. The base salaries have been targeted at or above the average rates paid by competitors to enable the Company to attract, motivate, reward and retain highly skilled executives. In order to evaluate the Company's competitive position in the industry, the Committee reviewed and analyzed the compensation packages, including base salary levels, offered by other biotechnology and pharmaceutical companies. The competitive information was obtained from surveys prepared by consulting companies or industry associations (e.g., the Radford Biotechnology Compensation Survey). As a general matter, the base salary for each executive officer is initially established through negotiation at the time the officer is hired taking into account such officer's qualifications, experience, prior salary, and competitive salary information. Year-to-year adjustments to each executive officer's base salary are based upon personal performance for the year, changes in the general level of base salaries of persons in comparable positions within the industry, and the average merit salary increase for such year for all employees of the Company established by the Compensation Committee, as well as other factors the Compensation Committee judges to be pertinent during an assessment period. In making base salary decisions, the Committee exercises its judgment to determine the appropriate weight to be given to each of these factors. ANNUAL INCENTIVE COMPENSATION A portion of the cash compensation paid to the Company's executive officers, including the Chief Executive Officer, is in the form of discretionary bonus payments that are paid on an annual basis as part of the Company's Incentive Compensation Plan. Bonus payments are linked to the attainment of overall corporate goals established by the Board of Directors and individual goals established for each executive officer. The maximum potential amount of each officer's bonus payment is established annually by the Board of Directors based upon the recommendation of the Committee. The appropriate weight to be given to each of the various goals used to calculate the amount of each officer's bonus payment is determined by the Committee. The goal of the Company's Incentive Compensation Plan is to support the achievement of Company goals and objectives by basing compensation on a pay for performance basis.

LONG-TERM INCENTIVES The Committee provides the Company's executive officers with long-term incentive compensation through grants of stock options under the Company's 1992 Incentive Stock Plan and the opportunity to purchase stock under the 1996 Employee Stock Purchase Plan (the "Purchase Plan"). The Board believes that stock options provide the Company's executive officers with the opportunity to purchase and maintain an equity interest in the Company and to share in the appreciation of the value of the Company's Common Stock. The Board believes that stock options directly motivate an executive to maximize long-term shareholder value. The options also utilize vesting periods (generally four years) that encourage key executives to continue in the employ of the Company. The Board considers the grant of each option subjectively, considering factors such as the individual performance of the executive officer and the anticipated contribution of the executive officer to the attainment of the Company's long-term strategic performance goals. Long-term incentives granted in prior years are also taken into consideration. The Company established the Purchase Plan both to encourage employees to continue in the employ of the Company and to motivate employees through ownership interest in the Company. Under the Purchase Plan, employees, including officers, may have up to 15% of their earnings withheld for purchases of Common Stock on certain dates specified by the Board. The price of Common Stock purchased will be equal to 85% of the lower of the fair market value of the Common Stock on the date of commencement of participation in each six-month offering period or on each specified purchase date. CHIEF EXECUTIVE OFFICER COMPENSATION The compensation of the Chief Executive Officer is reviewed annually on the same basis as discussed above for all executive officers. Gary A. Lyons' base salary for 1998 was $328,300 until March 1, 1998, when it became $346,375. Mr. Lyons' base salary for 1999 was set at $365,000. Mr. Lyons joined the Company in February 1993. His initial salary, potential bonus, and stock grants were determined on the basis of negotiation between the Board of Directors and Mr. Lyons with due regard for his qualifications, experience, prior salary, and competitive salary information. Mr. Lyons' base salary for 1999 was established in part by comparing the base salaries of chief executive officers at other biotechnology and pharmaceutical companies of similar size. Mr. Lyons earned a $50,000 bonus for 1998. As with other executive officers, Mr. Lyons' total compensation was based on the Company's accomplishments and the Chief Executive Officer's contribution thereto. SECTION 162(M) The Board has considered the potential future effects of Section 162(m) of the Code on the compensation paid to the Company's executive officers. Section 162(m) disallows a tax deduction for any publicly-held corporation for individual compensation exceeding $1.0 million in any taxable year for any of the executive officers named in the proxy statement, unless compensation is performance-based. The Company has adopted a policy that, where reasonably practicable, the Company will seek to qualify the variable compensation paid to its executive officers for an exemption from the deductibility limitations of Section 162(m). In approving the amount and form of compensation for the Company's executive officers, the Committee will continue to consider all elements of the cost to the Company of providing such compensation, including the potential impact of Section 162(m).
