Dear Bill:

This letter constitutes the agreement (the "Agreement") between you and

stock options granted to you as of the date of this Agreement will be
accelerated by one year upon either of the following events:

    A.   The termination of your employment by you for "Good Reason" (as defined

         (other than for "Cause," as defined in Section 3 below) within eighteen
         (18) months after a Change of Control.

In addition, if the effective date of any such termination of your
employment is 6 months or less from your next vesting date, an additional
number of options will vest equal to (i) the total number of options that
would have vested on your next vesting date, multiplied by (ii) a fraction,
the numerator of which equals the number of months from the date of your
last vesting and the effective date of your termination of employment, and
the denominator of which is 12.

2.  Change of Control.  For purposes of this Agreement, "Change of Control"
    -----------------
shall mean the occurrence of any of the following events: (i) the

corporation, other than a merger or consolidation which would result in the

continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) at least fifty
percent (50%) of the total voting power represented by the voting
securities of the Company or such surviving entity outstanding immediately
after such merger or consolidation; (ii) the consummation of the sale or
disposition by the Company of all or substantially all of the Company's
assets; or (iii) any person (as such term is used in Section 13(d) of the
Securities Exchange Act of 1934, as amended) becomes the beneficial owner
(as defined in Rule 13d-3 under said Act), directly or indirectly, of
