                (i)     Employee's willful misconduct or gross negligence in
                        performance of his duties hereunder, including
                        Employee's refusal to comply in any material

                        respect with the legal directives of the Board so long
                        as such directives are not inconsistent with the
                        Employee's position and duties, and such refusal to
                        comply is not remedied within fifteen (15) working days
                        after written notice from the Company, which written
                        notice shall state that failure to remedy such conduct
                        may result in Termination for Cause;

                (ii)    Dishonest or fraudulent conduct related and materially
                        adverse to the activities of the Company, a deliberate
                        attempt to do a material injury to the Company, or

                        theft or other misappropriation of the Company's
                        proprietary information.


        (b)     "Constructive Termination" shall be deemed to occur if (I)(1)
                there is a significant reduction in Employee's duties, positions
                or responsibilities causing such position to be of reduced
                stature or responsibility or, (2) a reduction in Employee's base
                compensation or benefits; and (ii) within the 60-day period
                immediately following such material change or reduction

                during any consecutive twelve-month period, if shorter, after
                its commencement, is determined to be total and permanent by an
                independent and impartial physician selected by the Company and
                its insurers and acceptable to Employee or to Employee's legal
                representative (with such agreement or acceptability not to be
                unreasonably withheld).

        (d)     "Change of Control" shall mean the occurrence of any of the
                following events: (i) an acquisition of the Company by another
                entity by means of any transaction or series of related
                transactions (including, without limitation, any reorganization,
                merger or consolidation but excluding any merger effected
                exclusively for the purpose of changing the domicile of the
                Company), or (ii) a sale of all or substantially all of the
                assets of the Company (collectively a "Merger"), so long as in

                prior to such Merger will, immediately after such Merger, hold
                less than 50% of the voting power of the surviving or acquiring
                entity, or (y) the Company's stockholders of record immediately
                prior to such Merger will, immediately after such Merger, hold
                less than 60% of the voting power of the surviving or acquiring
                entity and a majority of the members of the Board of Directors
                of the surviving or acquiring entity immediately after such
                Merger were not members of the Board of Directors of the Company
                immediately prior to such Merger.

9.      SUCCESSORS. Any successor to the Company (whether direct or indirect
        and whether by purchase, loan, merger, consolidation, liquidation or
        otherwise) or to all or substantially

   7

        all of the Company's business and/or assets shall assume the obligations
        under this Agreement and agree expressly to perform the obligations
        under this Agreement in the same manner and to the same extent as the
        Company would be required to perform such obligations in the absence of
        a succession. The terms of this Agreement and all of Employee's rights
        hereunder shall inure to the benefit of, and be enforceable by,
        Employee's personal or legal representatives, executors, administrators,
        successors, heirs, distributees, devisees and legatees.

10.     MISCELLANEOUS PROVISIONS.

        (a)     NO DUTY TO MITIGATE. Employee shall not be required to mitigate
                the amount of any payment contemplated by this Agreement
                (whether by seeking new employment or in any other manner), nor,
                except as otherwise provided in this Agreement, shall any such
                payment be reduced by any earnings that Employee may receive
                from any other source.

        (b)     AMENDMENTS AND WAIVERS. Any term of this Agreement may be
                amended or waived only with the written consent of the parties.

        (c)     SOLE AGREEMENT. This Agreement, including any exhibits hereto,
                constitutes the sole agreement of the parties and supersedes
                all oral negotiations and prior writings with respect to the
                subject matter hereof, including the Employment Agreement, dated
                May 30, 2001 between the Company and Employee.

        (d)     NOTICES. Any notice required or permitted by this Agreement
                shall be in writing and shall be deemed sufficient upon receipt,
                when delivered personally or by a nationally-recognized delivery
                service (such as Federal Express or UPS), or 48 hours after
                being deposited in the U.S. mail as certified or registered mail
                with postage prepaid, if such notice is addressed to the party
                to be notified at such party's address as set forth below or as
                subsequently modified by written notice.

        (e)     CHOICE OF LAW. The validity, interpretation, construction and
                performance of this Agreement shall be governed by the laws of
                the State of California, without giving effect to the
                principles of conflict of laws.

        (f)     SEVERABILITY. If one or more provisions of this Agreement are
                held to be unenforceable under applicable law, the parties agree
                to renegotiate such provision in good faith. In the event that
                the parties cannot reach a mutually agreeable and enforceable
                replacement for such provision, then (i) such provision shall be
                excluded from this Agreement, (ii) the balance of the Agreement
                shall be interpreted as if such provision were so excluded and
                (iii) the balance of the Agreement shall be enforceable in
                accordance with its terms.

        (g)     COUNTERPARTS. This Agreement may be executed in counterparts,
                each of which shall be deemed an original, but all of which
                together will constitute one and the same instrument.
