                                    RECITALS

     1. The Company and Executive have entered into a Change of Control
Severance Agreement (the "Agreement") with an effective date of October 13,
2005, as previously amended;

     2. The Board, acting upon the recommendation of its Compensation Committee,
has determined that it is in the best interests of the Company and its
stockholders to offer the Executive this Amendment;

                                    AMENDMENT

     NOW, THEREFORE, in consideration of the mutual covenants contained herein
and the continued employment of Executive by the Company, the parties agree as
follows:

     1. Amended and Restated Section 3(a). Section 3(a) is hereby amended and
restated to read as follows:

          "(a) Involuntary Termination Following a Change of Control. If within
twenty-four (24) months following a Change of Control (A) the Executive
terminates his or her employment with the Company (or any parent or subsidiary
of the Company) for "Good Reason" (as defined herein) or the Company (or any
parent or subsidiary of the Company) terminates the Executive's employment for
other than "Cause" (as defined herein), and (B) the Executive signs the
Company's standard separation agreement and release of claims with the Company,
then the Executive shall be entitled to receive the following severance benefits
from the Company: (i) a lump sum amount equal to two (2) times the sum of (x)
Executive's then-current base salary plus (y) a payment equal to Executive's
annual bonus target for the performance year in which the Change in Control
occurs, or if such amount is not determinable, Executive's annual bonus paid or
payable, including any bonus or portion thereof which has been earned but
deferred, for the most recently completed fiscal year; and (ii) reimbursement
for full COBRA (for the Executive and any of Executive's dependents that
Executive had elected to cover by Company's benefit plans during Executive's
employment at the Company) expenses for the earlier of eighteen (18) months or
until Executive receives health, medical and/or dental benefits, respectively,
from a new employer. In addition, Executive's outstanding options to purchase
shares of the Company's Common Stock (the "Options") and unvested restricted
shares of the Company's Common Stock (the "Restricted Stock") shall immediately
vest and, in the case of Options, become exercisable. In all other respects the
Options and Restricted Stock shall continue to be bound by and subject to the
terms of their respective agreements."
