          RE: OPTIONS UNDER 1996 & 1998 STOCK PLANS

Dear Optionee:

          We are pleased to inform you that on February 4, 2000, the Board of
Directors adopted a policy of accelerated vesting following a Change in Control,
as defined in the Company's 1996 & 1998 Stock Plans. The following provision is
now incorporated into your option:

          If (i) the Company is subject to a Change in Control before the
     Optionee's Service terminates, (ii) the Right of Repurchase is assigned to
     the acquiring entity or to its parent or subsidiary and (iii) there is an
     Involuntary Termination of Optionee's Service within twelve (12) months
     following the Change in Control, the Right of Repurchase shall
     automatically lapse and all of Optionee's Shares shall become vested.

          "INVOLUNTARY TERMINATION" means the termination of the Service of any
     individual which occurs by reason of: such individual's involuntary
     dismissal or discharge by the Company for reasons other than Misconduct, or
     such individual's voluntary resignation following (A) a reduction in his or
     her level of cash compensation (including base salary and participation in
     cash bonus or cash incentive programs) or (B) a relocation of such
     individual's place of employment by more than fifty (50) miles, provided
     and only if such reduction or relocation is effected by the Company without
     the individual's consent.

          "MISCONDUCT" means the commission of any act of fraud, embezzlement or
     dishonesty by the Optionee, any unauthorized use or disclosure by such
     person of confidential information or trade secrets of the Company (or any
     Parent or Subsidiary), or any other intentional misconduct by such person
     adversely affecting the business or affairs of the Company (or any Parent
     or Subsidiary) in a material manner. The foregoing definition shall not be
     deemed to be inclusive of all the acts or omissions which the Company (or
     any Parent or Subsidiary) may

     consider as grounds for the dismissal or discharge of any Optionee or other
     person in the Service of the Company (or any Parent or Subsidiary).

          Notwithstanding anything to the contrary contained herein, in the
     event that the Company is a party to a merger or consolidation, outstanding
     options of the Optionee shall not be subject to cancellation without
     payment of any consideration.

          Miscellaneous. This Agreement shall be binding upon the Company, its
successors and assigns (including, without limitation, the surviving entity or
successor party resulting from the Change in Control) and shall be construed and
interpreted under the laws of the State of California. This Agreement supersedes
all prior agreements between you and the Company relating to the subject matter
hereof. The Option Agreement shall remain in full force and effect except to the
extent necessary to give effect to the terms of this letter agreement.

          Please attach this letter amending your option to the agreement
evidencing your option.

Very truly yours,

     individual which occurs by reason of: such individual's involuntary
     dismissal or discharge by the Company for reasons other than Misconduct, or
     Optionee's voluntary resignation following (A) a change in his or her
     position with the Company which materially reduces his or her level of
     responsibility (but not a change resulting solely from the fact that the
     Company is no longer an independent company), (B) a reduction in his or her
     level of cash compensation (including base salary and participation in cash
     bonus or cash incentive program), but not the substitution of substantially
     equivalent compensation or (C) a relocation of such individual's place of
     employment by more than fifty (50) miles, provided and only if such change,
     reduction or relocation is effected by the Company without the individual's
     consent.
