PART II ITEM 3. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE. The following documents filed by the Company with the Securities and Exchange Commission are incorporated by reference into this Registration Statement: (a) The Company's Annual Report on Form 10-K for the year ended December 31, 1995 (File No. 0-22788), including all material incorporated by reference therein; (b) The Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 1996 (File No. 0-22788), as amended, including all material incorporated by reference therein; (c) The Company's Current Report on Form 8-K (File No. 0-21888), dated January 5, 1996; and (d) The description of the Common Stock contained in the Company's Registration Statement on Form 8-A (File No. 0-22788).

ITEM 4. DESCRIPTION OF SECURITIES Not Applicable ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. The validity of the shares of Common Stock offered hereby will be passed upon for the Company by Cooley Godward Castro Huddleson & Tatum ("CGCH&T"), Palo Alto, California. CGCH&T and certain attorneys in such firm own an aggregate of approximately 10,108 shares of the Company's Common Stock. Alan C. Mendelson, a partner of CGCH&T, is the Secretary of the Company. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Under Section 145 of the Delaware General Corporation Law the Company has broad powers to indemnify its directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act. The Company's Bylaws also provide the Company will indemnify its directors and executive officers, and may indemnify its other officers, employees and other agents, to the fullest extent not prohibited by Delaware law. The Company's Certificate of Incorporation provides for the elimination of liability for monetary damages for breach of the directors' fiduciary duty of care to the Company and its stockholders. These provisions do not eliminate the directors' duty of care and, in appropriate circumstances, equitable remedies such an injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to the Company, for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for any transaction from which the director derived an improper personal benefit, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision does not affect a director's responsibilities under any other laws, such as the federal securities laws or state or federal environmental laws. The Company has entered into agreements with its directors and executive officers that require the Company to indemnify such persons against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred (including expenses of a derivative action) in connection with any proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or officer of the Company or any of its affiliated enterprises, provided such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Company and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The indemnification agreements also set forth certain procedures that will apply in the event of a claim for indemnification thereunder. In addition, the Company has entered into certain agreements in connection with the Company's equity financings which provide for the indemnification of directors and officers in certain circumstances, including indemnification for liabilities arising under the Securities Act of 1933, as amended. The Company also II-1 maintains an insurance policy for its directors and officers insuring against certain liabilities arising in their capacities as such. ITEM 7.

ITEM 9. UNDERTAKINGS. A. The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered II-2 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. B. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-3 SIGNATURES THE REGISTRANT. Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of South San Francisco, State of California, on July 29, 1996.

ADMINISTRATION OF THE PLAN. (a) PROCEDURE. The Board may delegate administration of the Plan to a committee composed of not fewer than two (2) members (the "Committee"), all of the members of which Committee shall be Disinterested Persons and may also be, in the discretion of the Board, Outside Directors. 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 (and references in this Plan to the Board shall thereafter be to the Committee), 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. Notwithstanding anything in this Section 4 to the 3 contrary, the Board or the Committee may delegate to a committee of one or more members of the Board the authority to grant options to eligible persons who are not then subject to Section 16 of the Exchange Act and to eligible persons with respect to whom the Company does not wish to comply with Section 162(m) of the Code. Any requirement that an administrator of the Plan be a Disinterested Person shall not apply if the Board or the Committee expressly declares that such requirement shall not apply. Any Disinterested Person shall otherwise comply with the requirements of Rule 16b-3. (b) POWERS OF THE ADMINISTRATOR. Subject to the provisions of the Plan and in the case of a duly authorized committee, the specific duties delegated by the Board to such duly authorized committee, the Administrator shall have the authority, in its discretion: (i) to determine the Fair Market Value of the Common Stock, in accordance with Section 2(k) of the Plan; (ii) to select the officers, Consultants and Employees to whom Options and Stock Purchase Rights may from time to time be granted hereunder; (iii) to determine whether and to what extent Options and Stock Purchase Rights or any combination thereof, are granted hereunder; (iv) to determine the number of shares of Common Stock to be covered by each such award granted hereunder; (v) to approve forms of agreement for use under the Plan; (vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder (including, but not limited to, the share price and any restriction or limitation, regarding any Option or other award and/or the shares of Common Stock relating thereto, based in each case on such factors as the Administrator shall determine, in its sole discretion); (vii) to determine whether and under what circumstances an Option may be settled in cash under subsection 9(f) instead of Common Stock; (viii) to determine whether, to what extent and under what circumstances Common Stock and other amounts payable with respect to an award under this Plan shall be deferred either automatically or at the election of the participant (including providing for and determining the amount, if any, of any deemed earnings on any deferred amount during any deferral period); (ix) to reduce the exercise price of any Option to the then current Fair Market Value if the Fair Market Value of the Common Stock covered by such Option shall have declined since the date the Option was granted; and 4 (x) to determine the terms and restrictions applicable to Stock Purchase Rights and the Restricted Stock purchased by exercising such Stock Purchase Rights. (c) EFFECT OF COMMITTEE'S DECISION. All decisions, determinations and interpretations of the Administrator shall be final and binding on all Optionees and any other holders of awards granted under the Plan. 5. ELIGIBILITY. (a) Stock Purchase Rights may be granted to Employees and Consultants. (b) Nonstatutory Stock Options may be granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees. An Employee or Consultant who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options. (c) A director shall in no event be eligible for the benefits of the Plan unless at the time discretion is exercised in the selection of the director as a person to whom Options may be granted, or in the determination of the number of shares which may be covered by Options granted to the director: (A) the Board has delegated its discretionary authority over the Plan to a Committee which consists solely of Disinterested Persons; or (B) the Plan otherwise complies with the requirements of Rule 16b-3. The Board shall otherwise comply with the requirements of Rule 16b-3. This subsection 5(c) shall not apply if the Board or Committee expressly declares that it shall not apply. (d) Each Option shall be designated in the written option agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value of the Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionees during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. (e) No person shall be eligible to be granted Options covering more than three hundred thousand (300,000) shares of the Company's Common Stock in any calendar year. (f) For purposes of Section 5(d), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. (g) The Plan shall not confer upon any grantee of an award under the Plan any right with respect to continuation of employment or consulting relationship with the Company, nor shall it interfere in any way with his right or the Company's right to terminate his employment or consulting relationship at any time, with or without cause. 5 6. TERM OF PLAN. The Plan shall be come effective upon the earlier to occur of its adoption by the Board of Directors or its approval by the Shareholders of the Company as described in Section 19 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 15 of the Plan. 7. TERM OF OPTION. The term of each Option shall be the term stated in the Option Agreement; provided, however, that in the case of an Incentive Stock Option, the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. However, in the case of an Option granted to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 8. OPTION EXERCISE PRICE AND CONSIDERATION. (a) The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Board, but shall be subject to the following: (i) In the case of an Incentive Stock Option (A) granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. (B) granted to any Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. (ii) In the case of a Nonstatutory Stock Option (A) granted to a person who, at the time of the grant of such Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent of Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of the grant. (B) granted to any person, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant. (b) The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist entirely of (1) cash, (2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares acquired upon exercise of an Option either have been owned by the Optionee for more 6 than six months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, (5) authorization from the Company to retain from the total number of Shares as to which the Option is exercised that number of Shares having a Fair Market Value on the date of exercise equal to the exercise price for the total number of Shares as to which the Option is exercised, (6) delivery of a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds required to pay the exercise price, (7) by delivering an irrevocable subscription agreement for the Shares which irrevocably obligates the option holder to take and pay for the Shares not more than twelve months after the date of delivery of the subscription agreement, (8) any combination of the foregoing methods of payment, (9) or such other consideration and method of payment for the issuance of Shares to the extent permitted under Applicable Laws. In making its determination as of the type of consideration to accept, the Board shall consider if acceptance of such consideration may be reasonably expected to benefit the Company (Section 153 of the Delaware Corporation law). 9. EXERCISE OF OPTION. (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Board, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. An Option may not be exercised for a fraction of a Share. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Board, consist of any consideration and method of payment allowable under Section 8(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate promptly upon exercise of the Option. No adjustment will be made for a divided or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 13 of the Plan. Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. (b) TERMINATION OF EMPLOYMENT. In the event of termination of an Optionee's consulting relationship or Continuous Status as an Employee with the Company (as the case may be), such Optionee may, but only within ninety (90) days (or such other period of 7 time as is determined by the Board, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option and not exceeding ninety (90) days) after the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise his Option of the extent that Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of such termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. (c) DISABILITY OF OPTIONEE. Notwithstanding the provisions of Section 9(b) above, in the event of termination of an Optionee's Consulting relationship or Continuous Status as an Employee as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only within twelve (12) months from the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise the Option to the extent otherwise entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. (d) DEATH OF OPTIONEE. In the event of the death of an Optionee, the Option may be exercised, at any time within twelve (12) months following the date of death (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent the Optionee was entitled to exercise the Option at the date of death. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. (e) RULE 16B-3. Options granted to persons subject to Section l6(b) of the Exchange Act must comply with Rule 16-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. (f) BUYOUT PROVISIONS. The Administrator may at any time offer to buy out for a payment in cash or Shares, an Option previously granted, based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 10. NON-TRANSFERABILITY OF OPTIONS. The Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. 8 11. STOCK PURCHASE RIGHTS. (a) RIGHTS TO PURCHASE. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid (which price shall not be less than 50% of the Fair Market Value of the Shares as of the date of the offer), and the time within which such person must accept such offer, which shall not exceed thirty (30) days (or such longer time as may be determined by the Administrator) from the date upon which the Administrator made the determination to grant the Stock Purchase Right. The offer shall be accepted by execution of a Restricted Stock purchase agreement in the form determined by the Administrator. Shares purchased pursuant to the grant of a Stock Purchase Right shall be referred to herein as "Restricted Stock." (b) REPURCHASE OPTION. Unless the Administrator determines otherwise, the Restricted Stock purchase agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser's employment with the Company for any reason (including death or disability). The purchase price for Shares repurchased pursuant to the Restricted Stock purchase agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Committee may determine. (c) OTHER PROVISIONS. The Restricted Stock purchase agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock purchase agreements need not be the same with respect to each purchaser. (d) RIGHTS AS A STOCKHOLDER. Once the Stock Purchase Right is exercised, the purchaser shall have the rights equivalent to those of a stockholder, and shall be a shareholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 13 of the Plan. 12. STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS. At the discretion of the Administrator, grantees of an Option or Stock Purchase Right may satisfy withholding obligations as provided in this paragraph. When a grantee incurs tax liability in connection with an Option or Stock Purchase Right, which tax liability is subject to tax withholding under applicable tax laws, and the grantee is obligated to pay the Company an amount required to be withheld under applicable tax laws, the grantee may satisfy the withholding tax obligation by electing to have the Company withhold from the Shares to be issued upon exercise of the Option, or the Shares to be issued in connection with the Stock Purchase Right, if any, that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be 9 determined on the date that the amount of tax to be withheld is to be determined (the "Tax Date"). All elections by a grantee to have Shares withheld for this purpose shall be made in writing in a form acceptable to the Administrator and shall be subject to the following restrictions: (a) the election must be made on or prior to the applicable Tax Date; (b) once made, the election shall be irrevocable as to the particular Shares of the Option or Right as to which the election is made; (c) all elections shall be subject to the consent or disapproval of the Administrator; (d) if the grantee is subject to Rule l6b-3, the election must comply with the applicable provisions of Rule l6b-3 and shall be subject to such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. In the event the election to have Shares withheld is made by a grantee and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the grantee shall receive the full number of Shares with respect to which the Option or Stock Purchase Right is exercised but such grantee shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 13. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option. 10 In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the Optionee at least fifteen (15) days prior to such proposed action. To the extent it has not been previously exercised, the Option will terminate immediately prior to the consummation of such proposed action. In the event of a merger of the Company with or into another corporation, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation. 14. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for all purposes, be the date on which the Administrator makes the determination granting such Option, or such other date as is determined by the Board. Notice of the determination shall be given to each Employee or Consultant to whom an Option is so granted within a reasonable time after the date of such grant. 15. AMENDMENT AND TERMINATION OF THE PLAN. (a) AMENDMENT AND TERMINATION. The Board may at any time amend, alter, suspend or discontinue the Plan, but no amendment, alteration, suspension or discontinuation shall be made which would impair the rights of any grantee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with Rule 16b-3 under the Exchange Act or with Sections 162(m) or 422 of the Code (or any other applicable law or regulation, including the requirements of the NASD or an established stock exchange), the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required. (b) EFFECT OF AMENDMENT OR TERMINATION. Any such amendment or termination of the Plan shall not affect Options or Stock Purchase Rights already granted and such awards shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the grantee and the Board, which agreement must be in writing and signed by the grantee and the Company. 16. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law. 11 17. RESERVATION OF SHARES. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 18. AGREEMENTS. Options and Stock Purchase Rights shall be evidenced by written agreements in such form as the Board shall approve from time to time. 19. SHAREHOLDER APPROVAL. Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve (12) months before or after the date the Plan is adopted. Such shareholder approval shall be obtained in the degree and manner required under applicable state and federal law. 20. INFORMATION TO OPTIONEE. The Company shall provide to each Optionee, during the period for which such Optionee has one or more Options outstanding, copies of all annul reports and other information which are provided to all shareholders of the Company. The Company shall not be required to provide such information if the issuance of Options under the Plan is limited to key employees whose duties in connection with the Company assure their access to equivalent information. 12 EX-99.3 5 EMPLOYEE STOCK PURCHASE PLAN Exhibit 99.3 ARRIS PHARMACEUTICAL CORPORATION EMPLOYEE STOCK PURCHASE PLAN ADOPTED BY THE BOARD OCTOBER 1, 1993 APPROVED BY STOCKHOLDERS OCTOBER 5, 1993 AS AMENDED BY THE BOARD FEBRUARY 27, 1996 APPROVED BY STOCKHOLDERS JUNE 5, 1996 1. PURPOSE. (a) The purpose of the Employee Stock Purchase Plan (the "Plan") is to provide a means by which employees of Arris Pharmaceutical Corporation, a Delaware corporation (the "Company"), and its Affiliates, as defined in subparagraph 1(b), which are designated as provided in subparagraph 2(b), may be given an opportunity to purchase stock of the Company. (b) The word "Affiliate" as used in the Plan means any parent corporation or subsidiary corporation of the Company, as those terms are defined in Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986, as amended (the "Code"). (c) 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. (d) The Company intends that the rights to purchase stock of the Company granted under the Plan be considered options issued under an "employee stock purchase plan" as that term is defined in Section 423(b) of the Code. 2. ADMINISTRATION. (a) 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 subparagraph 2(c). 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. (b) 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. 1 (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. (c) The Board may delegate administration of the Plan to a Committee composed of not fewer than two (2) 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. 3. SHARES SUBJECT TO THE PLAN. (a) 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 two hundred fifty thousand (250,000) 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. (b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 4. 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. 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 Offering or otherwise) the substance of the provisions contained in paragraphs 5 through 8, inclusive. 2 5. ELIGIBILITY. (a) 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 at least twenty (20) hours per week and at least five (5) months per calendar year. (b) 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; (ii) the Offering Period for 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 Period for such 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 3 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. 6. RIGHTS; PURCHASE PRICE. (a) 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 not exceeding fifteen percent (15%) of such employee's Earnings (as defined in Section 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 more than twenty-seven (27) months after the Offering Date (the "Offering Period"). In connection with each Offering made under this Plan, the Board or the Committee shall specify a maximum number of shares which may be purchased by any employee as well as a maximum aggregate number of shares which may be purchased by all eligible employees pursuant to such Offering. In addition, in connection with each Offering which contains more than one Purchase Date (as defined in the Offering), the Board or the Committee may specify a maximum aggregate number of shares which may be purchased by all eligible employees on any given 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. (b) 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. 7. PARTICIPATION; WITHDRAWAL; TERMINATION. (a) An eligible employee may become a participant in 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 Period. "Earnings" is defined as the total compensation paid to an employee, including all salary, wages (including amounts elected to be deferred by the 4 employee, that would otherwise have been paid, under any cash or deferred arrangement established by the Company), overtime pay, commissions, bonuses, and other remuneration paid directly to the employee, but excluding profit sharing, the cost of employee benefits paid for by the Company, education or tuition reimbursements, imputed income arising under any Company group insurance or benefit program, traveling expenses, business and moving expense reimbursements, income received in connection with stock options, contributions made by the Company under any employee benefit plan, and similar items of compensation. 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), increase or begin such payroll deductions after the beginning of any Purchase Period only as provided for in the Offering. (b) At any time during an Offering Period 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 Period 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. (c) Rights granted pursuant to any Offering under the Plan shall terminate immediately upon cessation of any participating employee'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. (d) Rights granted under the Plan shall not be transferable, and, except as provided in Section 14, shall be exercisable only by the person to whom such rights are granted. 8. EXERCISE. (a) On each purchase date, as defined in the relevant Offering (a "Purchase Date"), 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. 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 5 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 the final Purchase Date of the Offering, 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. (b) No rights granted under the Plan may be exercised to any extent unless the Plan (including rights granted thereunder) is covered by an effective registration statement pursuant to the Securities Act of 1933, as amended (the "Securities Act"). If on a Purchase Date of any Offering hereunder the Plan is not so registered, no rights granted under the Plan or any Offering shall be exercised on said Purchase Date and the Purchase Date shall be delayed until the Plan is subject to such an effective registration statement, except that the Purchase Date shall not be delayed more than two (2) 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, no rights granted under the Plan or any Offering shall be exercised and all payroll deductions accumulated during the Offering Period (reduced to the extent, if any, such deductions have been used to acquire stock) shall be distributed to the participants, without interest. 9. COVENANTS OF THE COMPANY. (a) 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. (b) The Company shall seek to obtain from each 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. 10. 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. 6 11. 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 shareholdings acquired upon exercise of rights hereunder are recorded in the books of the Company. 12. ADJUSTMENTS UPON CHANGES IN STOCK. (a) 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 otherwise), 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. (b) 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) any other capital reorganization in which more than fifty percent (50%) of the shares of the Company entitled to vote are exchanged, then, as determined by the Board in its sole discretion (i) any surviving 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. 13. AMENDMENT OF THE PLAN. (a) 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, where the amendment will: (i) Increase the number of shares reserved for rights under the Plan; (ii) Modify the provisions as to eligibility for participation in the Plan (to the extent such modification 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 Securities Exchange Act of 1934, as amended ("Rule 16b-3")); or 7 (iii) Modify the Plan in any other way if such modification 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. It is expressly contemplated that 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.

GRANT; OFFERING DATE. The Board of Directors of Arris Pharmaceutical Corporation, a Delaware corporation (the "Company"), pursuant to the Company's Employee Stock Purchase Plan (the "Plan"), hereby authorizes the grant of rights to purchase shares of the common stock of the Company ("Common Stock") to all Eligible Employees (an "Offering"). The first Offering hereunder shall begin August 1, 1996 and end on July 31, 1998, unless terminated sooner as herein provided (the "1996 Offering"). Thereafter Offerings shall begin on August 1, 1998 and on each subsequent second anniversary of the most recent Offering Date (the first day of an Offering is that Offering's "Offering Date"); PROVIDED, HOWEVER, that if on any Purchase Date (as defined in Section 6 below) the fair market value of the Company's Common Stock is less than it was on the Offering Date for that Offering, the day after such Purchase Date (I.E., February 1 or August 1) shall become the next Offering Date and the Offering that would otherwise have continued in effect shall immediately terminate. Each Offering after the 1996 Offering shall end on the day prior to the second anniversary of its Offering Date unless sooner terminated as provided above. Prior to the commencement of any Offering, the Board of Directors or the Compensation Committee may change any or all terms of such Offering and any subsequent Offerings. The granting of rights pursuant to each Offering hereunder shall occur on each respective Offering Date unless, prior to such date (a) the Board of Directors or the Compensation Committee determines that such Offering shall not occur, or (b) no shares remain available for issuance under the Plan in connection with the Offering. 2. ELIGIBLE EMPLOYEES. (a) All employees of the Company and each of its Affiliates (as defined in the Plan) incorporated in the United States shall be granted rights to purchase Common Stock under each Offering on the Offering Date of such Offering, provided that each such employee otherwise meets the employment requirements of subparagraph 5(a) of the Plan and has been continuously employed by the Company for at least three months (an "Eligible Employee"). Notwithstanding the foregoing, no employee who is disqualified by subparagraph 5(c) or 5(d) of the Plan shall be an Eligible Employee or be granted rights under an Offering. (b) Notwithstanding the foregoing, each person who first becomes an Eligible Employee after an Offering Date will on the next February 1st or August 1st during that Offering receive a right under such Offering, which right shall thereafter be deemed to be a part 1 of the Offering. Such right shall have the same characteristics as any rights originally granted under the Offering, except that: (1) 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; and (2) the Offering for such right shall begin on its Offering Date and end coincident with the end of the ongoing Offering. 3. RIGHTS. (a) Subject to the limitations contained herein and in the Plan, on each Offering Date each Eligible Employee shall be granted the right to purchase the number of shares of Common Stock purchasable with up to ten percent (10%) of such employee's Earnings (as defined in the Plan) paid during such Offering; PROVIDED, HOWEVER, that no employee may purchase Common Stock in a particular year with more than ten percent (10%) of such employee's Earnings in such year under all ongoing Offerings under the Plan and all other Company plans intended to qualify as "employee stock purchase plans" under Section 423 of the Internal Revenue Code of 1986, as amended. Notwithstanding the foregoing, the maximum number of shares of Common Stock an Eligible Employee may purchase on any Purchase Date (as defined in Section 6) in an Offering shall be the number of shares determined by dividing $12,500 by the fair market value of a share of the Common Stock on the Offering Date for such Offering. (b) The maximum aggregate number of shares available to be purchased by all Eligible Employees under an Offering shall be one hundred thousand (100,000) shares of Common Stock, or, if less, the number of shares remaining available under the Plan on the Offering Date. The maximum aggregate number of shares available to be purchased by Eligible Employees on any Purchase Date (as defined in Section 6) under an Offering shall be the lesser of (i) fifty thousand (50,000) shares of Common Stock, (ii) one hundred thousand (100,000) shares of Common Stock less any shares of Common Stock previously purchased on any Purchase Date during the Offering, or (iii) the number of shares remaining available under the Plan. If the aggregate purchase of shares of Common Stock upon exercise of rights granted under the Offering would exceed the maximum aggregate number of shares available, the Board shall make a pro rata allocation of the shares available in a uniform and equitable manner. 4. PURCHASE PRICE. The purchase price of the Common Stock shall be the lesser of eighty-five percent (85%) of the fair market value of the Common Stock on the Offering Date or eighty-five percent (85%) of the fair market value of the Common Stock on the Purchase Date, in each case rounded up to the nearest cent per share. 2 5. PARTICIPATION. An Eligible Employee may elect to participate in an Offering at the beginning of the Offering or any February 1st or August 1st during the Offering. An Eligible Employee shall become a participant in an Offering by delivering an agreement authorizing payroll deductions. Such deductions may be in whole percentages only, with a minimum percentage of one percent (1%), and a participant may not make additional payments into his or her account. The agreement shall be in such form as the Company provides, and must be delivered to the Company before the Offering Date or (February 1st or August 1st during an Offering) to be effective for the remaining portion of that Offering, unless a later time for filing the enrollment form is set by the Board for all Eligible Employees with respect to a given Offering. A participant may not increase or reduce his or her participation percentage during the course of an Offering except on each February 1st and August 1st. A participant may withdraw from an Offering and receive his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to acquire stock for the participant) from the Offering, without interest, at any time prior to the end of the Offering Period of the Offering by delivering a withdrawal notice to the Company in such form as the Company provides. 6. EXERCISE. Subject to the limitations contained herein, on each Purchase Date, each participant's accumulated payroll deductions (without any increase for interest) shall be applied to the purchase of whole shares of Common Stock, up to the maximum number of shares permitted under the Plan and the Offering. "Purchase Date" shall be defined as each January 31st and July 31st (I.E., the first Purchase Date of the 1996 Offering shall be January 31, 1997 and the next Purchase Date shall be July 31, 1997.) 7. NOTICES AND AGREEMENTS. Any notices or agreements provided for in an Offering or the Plan shall be given in writing, in a form provided by the Company, and unless specifically provided for in the Plan or this Offering shall be deemed effectively given upon receipt or, in the case of notices and agreements delivered by the Company, five (5) days after deposit in the United States mail, postage prepaid. 8. OFFERING SUBJECT TO PLAN. Each Offering is subject to all the provisions of the Plan, and its provisions are hereby made a part of the Offering, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of an Offering and those of the Plan (including interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan), the provisions of the Plan shall control. 3 -----END PRIVACY-ENHANCED MESSAGE-----
