defined herein. In the case of termination of employment under this Section 4.1,
Executive shall not be entitled to receive any payments or benefits under this
Agreement other than any unpaid Annual Salary which has accrued as of the date
Executive's employment terminates.

      4.2.  OTHER TERMINATION EXCLUDING CHANGE OF CONTROL

      Either Employer or Executive may terminate this agreement at any time for
any reason, with or without notice. Except as provided in Section 4.3.1 below,
upon such termination, Executive shall not be entitled to receive any payments
or benefits under this Agreement other than any unpaid Annual Salary and
vacation time which has accrued as of the date Executive's employment
terminates.

      Executive acknowledges and understands that his employment with the
Company is at-will and can be terminated by either party for no reason or for
any reason not otherwise specifically prohibited by law or provided for in this
Agreement. Nothing in this Agreement is intended to alter Executive's at-will
employment status or obligate the Company to continue to employ Executive for
any specific period of time, or in any specific role or geographic location.

      4.3.  TERMINATION AS A RESULT OF CHANGE OF CONTROL

            4.3.1. TERMINATION BY SUCCESSOR EMPLOYER

      If (a) during the period commencing on the date Employer enters into a
definitive agreement with respect to a transaction that would constitute a
Change of

                                      -3-
<PAGE>

Control (as defined below) and ending on the date the definitive agreement
therefor is terminated or the Change of Control is consummated, Employer
terminates Executive's employment without cause (as defined below), (b) during
the period commencing upon the consummation of the Change of Control and ending
twenty-four months thereafter, Employer or, if applicable, the surviving or
successor employer ("Successor Employer") terminates Executive's employment
without Cause (as defined below), or (c) during the period commencing upon the
consummation of the Change of Control and ending twenty-four (24) months
thereafter, Executive resigns for Good Reason (as defined below), then Executive
shall be entitled to receive the following termination payments and benefits:

            (1)   severance payments equal to six (6) months salary, to be paid
      out over six (6) months in the course of Employer's or the Surviving
      Employer's regularly scheduled payroll;

            (2)   continuation of health and other benefits, substantially
      equivalent to those in place as of the termination date, for six (6)
      months;

            (3)   any unpaid Annual Salary and unused vacation time which has
      accrued as of the date Executive's employment terminates; and

            (4)   accelerated vesting of 100% of Executive's then unvested
      options to purchase shares of Employer common stock or the options to
      purchase common stock of the Successor Employer issued in substitution
      therefor in connection with the Change of Control.

      The severance payments and benefits described in this paragraph are
expressly contingent upon Executive's signing upon termination a full release in
a form acceptable to Successor Employer, and are further contingent upon
Executive's full compliance with the terms of the Confidentiality Agreement (as
defined in paragraph 5 below) with Employer.

            4.3.2. TERMINATION FOR CAUSE

      If, during either of the periods set forth in clauses (a) or (b) of
Section 4.3.1, Executive voluntarily terminates his employment other than for
Good Reason, Executive shall not be entitled to receive any payments or benefits
hereunder other than any unpaid Annual Salary which has accrued as of the date
