employment relationship in accordance with the terms and conditions set forth
below.

1.    EMPLOYMENT

3.    COMPENSATION AND BENEFITS

      Employer agrees to pay or cause to be paid to Executive, and Executive
agrees to accept in exchange for the services rendered hereunder by him, the
following compensation:

      3.1   ANNUAL SALARY

      Executive's compensation shall consist of an annual base salary (the
"Annual Salary") of one hundred fifty thousand dollars ($150,000), before all
customary payroll deductions. The Annual Salary shall be reviewed, and shall be
subject to change, by the Board of Directors of Employer (or the Compensation
Committee thereof) at least annually while Executive is employed hereunder.

      3.2   BONUS

      Executive shall be eligible for bonuses in accordance with executive bonus
plans, which shall be adopted and modified from time to time in the sole
discretion of the Board of Directors (or the Compensation Committee of the Board
of Directors) of Employer.

      3.3   BENEFITS

      Executive will be entitled to participate, subject to and in accordance
with applicable eligibility requirements, in such benefit programs as shall be
provided from time to time by action of Employer's Board of Directors, which
shall include, at a minimum, basic health insurance.

      3.4   VACATION

      Executive shall be entitled to four (4) weeks vacation each year, during
which time Executive's compensation will continue in full. The vacation period
may not be carried over from year to year. Vacation will be scheduled by mutual
agreement.

4.    TERMINATION

      The employment of Executive pursuant to this Agreement may be terminated
as follows:

      4.1.  AUTOMATIC TERMINATION ON DEATH OR TOTAL DISABILITY

      This Agreement and Executive's employment hereunder shall terminate
automatically upon the death or total disability of Executive. The term "total

<PAGE>

disability" as used herein shall mean Executive's inability to perform the
duties set forth in Section 1 hereof for a period or periods aggregating ninety
(90) calendar days (or such other period as may be required by law) in any
twelve-month period as a result of physical or mental illness, loss of legal
capacity or any other cause beyond Executive's control, unless Executive is
granted a leave of absence by the Board of Directors of Employer (or the
Compensation Committee thereof). Executive and Employer hereby acknowledge that
Executive's ability to perform the duties specified in paragraph 1 hereof is of
the essence of this Agreement. Termination hereunder shall be deemed to be
effective (a) at the end of the calendar month in which Executive's death occurs
or (b) immediately upon a determination by the Board of Directors of Employer
(or the Compensation Committee thereof) of Executive's total disability, as
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 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-

<PAGE>

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 is terminated by Employer or the Successor Employer for
Cause, 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
Executive's employment terminates.

            4.3.3. TERMINATION BY EXECUTIVE

      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

<PAGE>

than any unpaid Annual Salary which has accrued as of the date Executive's
employment terminates.

            4.3.4. CAUSE

      Wherever reference is made in this Agreement to termination being with or
without Cause, "Cause" shall be limited to the occurrence of one or more of the
following events:

            (a) willful misconduct, insubordination, or dishonesty in the
      performance of Executive's duties or other knowing and material violation
      of Employer's or the Successor Employer's policies and procedures in
      effect from time to time which results in a material adverse effect on
      Employer or the Successor Employer;

            (b) the continued failure of Executive to satisfactorily perform his
      duties after receipt of written notice that identifies the areas in which
      Executive's performance is deficient;

            (c) willful actions (or intentional failures to act) in bad faith by
      Executive with respect to Employer or the Successor Employer that
      materially impair Employer's or the Successor Employer's business,
      goodwill or reputation;

            (d) conviction of Executive of a felony involving an act of
      dishonesty, moral turpitude, deceit or fraud, or the commission of acts
      that could reasonably be expected to result in such a conviction;

            (e) current use by the Executive of illegal substances; or

            (f) any material violation by Executive of Executive's
      Confidentiality Agreement.

            4.3.5. GOOD REASON

      his/her then current place of employment in order to continue to perform
      the duties and responsibilities of his/her position (not including
      customary travel as may be required by the nature of his/her position).

            4.3.6. CHANGE OF CONTROL

      For purposes of this Agreement, "Change of Control" means:

            (a) a merger or consolidation of the Company with or into any other
      company, entity or person or

            (b) a sale, lease, exchange or other transfer in one transaction or
      a series of transactions undertaken with a common purpose of all or
      substantially all of Employer's then outstanding securities or all or
