        This Amendment to Employment Agreement ("Amendment") is entered into as
of February 1, 2001 (the "Amendment Date"), by and between Richard Burns

business, and will, following the sale by the Company to NVIDIA Corporation of
certain specified assets, wind up its affairs and liquidate; and

        WHEREAS, the Company and the Executive have agreed to amend that certain
Employment Agreement dated as of October 20, 2000 (the "Agreement");

        NOW, THEREFORE, the parties agree as follows:

        1.      Section 1(a) of the Agreement is amended by adding the
                following:

                Executive agrees that he will devote substantially all of his
                business efforts toward enhancing shareholder return through
                performing those duties set forth on Schedule 1 to this
                Agreement.

        2.      Section 2(a) of the Agreement is amended by deleting therefrom
                the second and third sentences. Section 2(b) of the Agreement is
                deleted and replaced with the following:

                (b)     Termination. The Executive's employment shall terminate
                        on the earlier of (i) February 28, 2001, (ii) the date
                        on which the Executive has provided written notice to
                        the Company that his duties set forth on Schedule 1 have
                        been substantially completed, and upon which the Company
                        has provided written consent (which shall not be
                        unreasonably withheld), to early-terminate the
                        Executive's employment, (iii) the date that the Company
                        terminates Executive's employment without Cause, (iv)
                        the date of Executive's death or Disability, (v) the
                        date on which the Executive voluntarily resigns his
                        employment not in accordance with Subsection 2(b)(ii)
                        hereof, or (vi) the date on which Executive's employment
                        is terminated for Cause (the "Termination Date"). Prior
                        to the Termination Date, the Executive may terminate his
                        employment for any reason (or no reason) by giving the
                        Company fourteen (14) days' notice in writing.
                        Executive's employment shall terminate automatically in
                        the event of his death.
