Agreement entered into between the Company and Executive, the payments provided
by this Paragraph 5 shall commence within sixty (60) days of the Date of

        2.    Term.    Paragraph 1(b) of the Employment Agreement shall be

(50) miles from Executive's then present office location or locations.

The Corporation and Executive further agree that for a resignation to constitute

(30) days of one of the triggering events outlined in this Paragraph 8(d)(iv)."

        4.    Excess Parachute Payments.    The following shall be inserted at

        ", provided that, the Gross-Up Payment shall in all events be paid prior
to the last day of Executive's taxable year next following Executive's taxable
year in which the Excise Tax is remitted to the Internal Revenue Service or any
other applicable taxing authority."

        5.    Section 409A.    Paragraph 7 of the First Amendment is hereby
deleted in its entirety and replaced by this Paragraph 5.

        (a)    Separation from Service.    Notwithstanding anything in this
Amendment or the Agreements to the contrary, no termination benefits deemed
deferred compensation subject to Section 409A of the Code shall be payable
pursuant to the Agreements unless Executive's termination of employment
constitutes a "separation from service" with the Company within the meaning of
Section 409A of the Code and the Department of Treasury regulations and other
guidance promulgated thereunder (a "Separation from Service") and, except as
provided under Paragraph 5(b) of this Amendment, any such termination benefits
shall not be paid, or, in the case of installments, shall not commence payment,
until the sixtieth (60th) day following Executive's Separation from Service. Any
installment payments that would have been made to Executive during the sixty
(60) day period immediately following Executive's Separation from Service but
for the preceding sentence shall be paid to Executive on the sixtieth (60th) day
following Executive's Separation from Service and the remaining payments shall
be made as provided in the Agreements.

        (b)    Specified Employee.    Notwithstanding any provision to the
contrary in this Amendment or the Agreements, if Executive is deemed by the
Company at the time of his Separation from Service to be a "specified employee"
for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent delayed
commencement of any portion of the termination benefits to which Executive is
entitled under the Agreements is required in order to avoid a prohibited
distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of
Executive's benefits shall not be provided to Executive prior to the earlier of
(i) the expiration of the six-month period measured from the date of the
Executive's Separation from Service or (ii) the date of Executive's death. Upon
the first business day following the expiration of the applicable Code
Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this
Paragraph 5(b) shall be paid in a lump sum to Executive, and any remaining
payments due under the Agreements shall be paid as otherwise provided therein.

        (c)    Expense Reimbursements.    To the extent that any reimbursements
payable pursuant to the Agreements are subject to the provisions of Section 409A
of the Code, any such reimbursements payable to Executive pursuant to the
Agreements shall be paid to Executive no later than December 31 of the year
following the year in which the expense was incurred, the amount of expenses
reimbursed in one year shall not affect the amount eligible for reimbursement in
any subsequent year, and Executive's right to reimbursement under the Agreements
will not be subject to liquidation or exchange for another benefit.

        (d)    Installments.    For purposes of Section 409A of the Code
(including, without limitation, for purposes of Treasury Regulation
Section 1.409A-2(b)(2)(iii)), Executive's right to receive the

2

--------------------------------------------------------------------------------

installment payments under this Amendment and the Agreements shall be treated as
a right to receive a series of separate payments and, accordingly, each such
installment payment shall at all times be considered a separate and distinct
payment.

        6.    Continuation of Other Terms.    Except as set forth herein, all
other terms and conditions of the Agreements shall remain in full force and
effect.

        7.    Complete Agreement.    This Amendment and the Agreements
collectively constitute the entire agreement between Executive and the Company
with respect to the subject matter described herein and they are the complete,
final and exclusive embodiment of their agreement with regard to this subject
matter. However, if there are any ancillary benefits set forth in the form of
Executive Severance Agreement attached as Exhibit 10.2 to the Form 8-K filed by
the Company on March 22, 2007, as such form may be amended from time to time,
which are more beneficial to Executive in any respect than what is provided for
in this Amendment and/or the Agreements, such ancillary benefits shall be made
available to Executive. This Amendment is entered into without reliance on any
promise or representation other than those expressly contained herein.

        8.    Applicable Law.    This Amendment shall be governed by the law of
the State of California as such laws are applied to agreements between
California residents entered into and to be performed entirely within the State
of California.
