The aggregate number of shares to be registered is subject to adjustment by reason of stock splits, stock dividends and other events pursuant to the terms of the 2005 Plan or the ESPP, as applicable. Accordingly, pursuant to Rule 416 under the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement covers, in addition to the number of shares of common stock shown in the table above, an indeterminate number of shares of the Registrant’s common stock which may be subject to grant or otherwise issuable by operation of the provisions of the 2005 Plan or the ESPP governing such adjustments.
(2)   This Registration Statement also covers the rights to purchase shares of the Registrant’s Series X junior participating preferred stock issuable in accordance with the Amended and Restated Rights Agreement, dated as of July 26, 2001, between the Registrant and Mellon Investor Services LLC, as amended. These rights initially are attached to and trade with the Registrant’s common stock. The value attributed to such rights, if any, is reflected in the market price of the Registrant’s common stock.
(3)   The Registrant is carrying forward to this Registration Statement 3,857,448 shares of the Registrant’s common stock (including the associated rights to purchase Series X junior participating preferred stock) previously registered under its Registration Statement on Form S-8 (SEC File No. 333-110432).
(4)   Estimated pursuant to Rule 457(h) of the Securities Act, solely for the purpose of calculating the registration fee, on the basis of the average of the high and low selling prices of the Registrant’s common stock as reported on the Nasdaq National Market on September 14, 2005. The filing fee payable is $100,750. Of this amount, the Registrant offsets $6,836 in fees previously paid with respect to the shares of common stock carried forward to this Registration Statement from Registration Statement on Form S-8 (SEC File No. 333-110432). The remaining amount of fees payable of $93,915 has been transmitted as of the date hereof.
(5)   The registration fee has been calculated pursuant to Section 6(b) of the Securities Act by multiplying .0001177 by the proposed maximum aggregate offering price (as computed in accordance with Rule 457 under the Securities Act solely for the purpose of determining the registration fee of the securities registered hereby).

Table of Contents

     Pursuant to the Certificate of Incorporation, the Registrant’s board of directors is authorized to issue up to an aggregate of 8,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions, including the dividend rights, conversion rights, voting rights, rights and terms of redemption, redemption price or prices, liquidation preferences and the number of shares constituting any series or the designations of such series, without any further vote or action by the stockholders. The issuance of preferred stock in certain circumstances may have the effect of delaying, deferring or preventing a change of control of the Registrant without further actions of the stockholders. The issuance of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of common stock, including the loss of voting control to others.
     Preferred Stock Outstanding. As of June 30, 2005, there were 8,221 shares of Series A-2 preferred stock outstanding, all of which are owned by Genentech, Inc., and no other shares of preferred stock outstanding. The outstanding shares of Series A-2 preferred stock are duly authorized, validly issued, fully paid and non-assessable.
     Voting Rights. None of the Series A-2 preferred stock outstanding has voting rights, except as may be required by the Delaware General Corporation Law (the “DGCL”).
     Conversion. Each share of Series A-2 preferred stock is convertible at any time into 60 shares of the Registrant’s common stock. The outstanding shares of Series A-2 preferred stock automatically convert into common stock in the event that a person or entity other than Genentech or its affiliate acquires such shares. The conversion rate of the Series A-2 preferred stock is subject to adjustment for certain stock splits, stock dividends, combinations and other events.
     Dividend Rights; Rights Upon Liquidation. Under the terms of the outstanding Series A-2 preferred stock as set forth in the Certificate of Incorporation, no dividend shall be paid to holders of common stock (other than dividends of common stock) unless a dividend of equal or greater amount (calculated on an on an as-converted basis) is paid to holders of Series A-2 preferred stock. In the event of a liquidation, dissolution or winding up of the Registrant, holders of the outstanding Series A-2 preferred stock will have a right to receive a return of their original purchase price plus declared but unpaid dividends for their shares of preferred stock, prior to and in preference of any distribution of assets of the Registrant to any holder of common stock. Under the terms of the outstanding Series A-2 preferred stock as set forth in the Certificate of Incorporation, a liquidation is deemed to include any situation in which (i) a single stockholder or group of affiliated stockholders, other than Genentech or its controlled affiliate, who would be required to file a Schedule 13D under the Exchange Act, acquires or obtains the right to acquire voting stock of the Registrant so that its total holdings of such stock equal or exceed 50% of the then outstanding voting stock of the Registrant or (ii) any third party, other than Genentech or its controlled affiliate, acquires or obtains the right to acquire all or substantially all of the Registrant’s assets.
     Other Rights. There are no redemption or sinking fund provisions applicable to the Registrant’s outstanding Series A-2 preferred stock.
     Amended and Restated Rights Agreement and Series X Junior Participating Preferred Stock
     A description of the rights issued under the Registrant’s amended and restated rights agreement and of the registrant’s Series X junior participating preferred stock reserved for issuance in connection with such amended and restated rights agreement is set forth in the Registrant’s Registration Statement on Form 8-A/A filed with the Commission on July 27, 2001, as amended by a Form 8–A/A filed with the

Table of Contents

Commission on June 25, 2003, and any amendment or report updating such description of the such preferred stock purchase rights, which documents are incorporated by reference into this document.
     The Registrant’s amended and restated rights agreement may have anti-take-over effects. The rights may cause substantial dilution to a person or group that attempts to acquire the Registrant. Accordingly, the existence of the rights may deter acquirors from making takeover proposals or tender offers.
Item 5: Interests of Named Experts and Counsel
     The validity of the shares of common stock being registered by this Registration Statement has been passed upon by Skadden, Arps, Slate, Meagher & Flom LLP.
Item 6: Indemnification of Directors and Officers
     The Certificate of Incorporation provides that a director of the Registrant shall not be personally liable to the Registrant or its stockholders for monetary damages for any breach of fiduciary duty as a director, except for liability for (i) any breach of the director’s duty of loyalty to the Registrant or its stockholders; (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or (iv) any transaction from which the director derived an improper personal benefit. This provision has no effect on any non-monetary remedies that may be available to the Registrant or its stockholders, nor does it relieve the Registrant or its officers or directors from compliance with federal or state securities laws.
     The Certificate of Incorporation provides that to the fullest extent permitted by applicable law, the Registrant is authorized to provide indemnification of, and advancement of expenses to, such agents and any other persons to which Delaware law permits the Registrant to provide indemnification though bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the DGCL, subject only to limits created by applicable Delaware law, with respect to actions for breach of duty to the Registrant, its stockholders, and others.
     The Registrant’s Bylaws provide that the Registrant shall indemnify its directors to the fullest extent authorized under Delaware law, and that the Board of Directors of the Registrant shall have the power, on behalf of the Registrant, to indemnify any other person made party to any action, suit, or proceeding by reason of the fact that he, his testator or intestate, is or was an officer or employee of the Registrant. The Registrant’s Bylaws also provide that, except in specified circumstances, expenses incurred by a director of the registrant in defending a civil or criminal action, suit or proceeding by reason of the fact that he or she is or was a director of the Registrant (or was serving at the Registrant’s request as a director or officer of another corporation) shall be paid by the Registrant in advance of the final disposition of such action, suit or proceeding.
     Section 145 of the DGCL provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to

5


Table of Contents

believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances. Section 145 of the DGCL also provides that a corporation shall indemnify a director or officer of the corporation to the extent he or she has been successful on the merits or otherwise in defense of any such action, suit or proceeding, for expenses reasonably incurred in connection with such action, suit or proceeding.
     The Registrant has secured insurance on behalf of directors, officers and employees of the Registrant and its subsidiaries for liability arising out of certain claims which may be made against them, whether or not the Registrant would have the power to indemnify them against such liability under the DGCL.
     In addition to indemnification provided for in its Bylaws, the Registrant has entered into agreements with certain of its directors and officers to indemnify them for, among other things, certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by them in any action or proceeding, including any action by or in the right of the Registrant, to which they are a party by reason of the fact that they were or are a director, officer, employee or agent of the Registrant or of any other company or enterprise to which the person provides such services at the Registrant’s request.

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;
 
  (ii)   To reflect in the prospectus any facts or events arising after the effective date of this 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; and
 
  (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) of this section 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

7


Table of Contents

      Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act 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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and
 
  (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 this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, 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 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.
