possibility or occurrence of a change in control of the Company, and the Board
has established the Plan for this purpose. The purpose of the Plan is to provide
acceleration benefits in the event certain employees incur a Qualified
Termination during the Change in Control Period. The adoption of this Plan in no
event guarantees any employee acceleration benefits in the event she/he is
terminated by the Company or the Employer prior to a Change in Control.

SECTION 2. DEFINITIONS

(a) “Board” means the Board of Directors of the Company.

the information then known to the Employer, of one of the following:

(i) Eligible Employee’s gross neglect of, or willful failure or refusal to
timely perform, not caused by Eligible Employee’s physical or mental disability
and not solely based on Eligible Employee’s failure to accomplish any particular
budgeted goal, the material duties of Eligible Employee’s employment following
written notice and a reasonable opportunity (not to exceed 30 days) to cure, if
such neglect, failure or refusal is capable of being cured;

(ii) Eligible Employee’s material breach of the terms of any offer letter or
employment agreement between the Eligible Employee and his or her Employer, or
any other agreement (including the confidentiality agreement and/or proprietary
information agreement entered into in connection with Eligible Employee’s
employment) by and between the Eligible Employee and the Employer which causes
demonstrable injury to the Employer provided that Eligible Employee has received
written notice of the breach and a reasonable opportunity (not to exceed 30
days) to cure, if such breach is capable of being cured; or

(iii) Eligible Employee’s commission of, or plea of guilty or nolo contender to,
a crime involving moral turpitude, dishonesty, fraud or unethical business
conduct, or any felony.

termination for Cause.

previously granted to such Eligible Employee shall be extinguished and replaced
by the rights under this Plan.

SECTION 5. REDUCTION OF CERTAIN BENEFITS

(a) Reduction in Benefits. Anything in this Plan to the contrary
notwithstanding, in the event that the receipt of all payments or distributions
by the Company or the Employer in the nature of compensation to or for the
Eligible Employee’s benefit, whether paid or payable pursuant to this Plan or
otherwise (a “Payment”), would subject the Eligible

 

3

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

Employee to the excise tax under Section 4999 of the Code, the accounting firm
which audited the Company prior to the corporate transaction which results in
the application of such excise tax, or another nationally known accounting or
employee benefits consulting firm selected by the Company prior to such
corporate transaction (the “Accounting Firm”), shall determine whether to reduce
any of the Payments to the Reduced Amount (as defined below). The Payments shall
be reduced to the Reduced Amount only if the Accounting Firm determines that the
Eligible Employee would have a greater Net After-Tax Receipt (as defined below)
of aggregate Payments if the Eligible Employee’s Payments were reduced to the
Reduced Amount. If such a determination is not made by the Accounting Firm, the
Eligible Employee shall receive all Payments to which Eligible Employee is
entitled to receive.

(b) Order of Reduction. If the Accounting Firm determines that Payments should
be reduced to the Reduced Amount, the Company shall promptly give the Eligible
Employee notice to that effect and a copy of the detailed calculation thereof.
All determinations made by the Accounting Firm under this Section 5 shall be
made as soon as reasonably practicable and in no event later than 60 days
following the date of termination of employment or such earlier date as
requested by the Company and the Eligible Employee. All fees and expenses of the
Accounting Firm shall be borne solely by the Company. Any determination by the
Accounting Firm shall be binding on the Company, its Subsidiaries and the
Eligible Employee. For purposes of reducing the Payments to the Reduced Amount,
the Payments shall be reduced in the following order, in each case, in reverse
chronological order beginning with the Payments that are to be paid or become
vested the furthest in time from consummation of the Change in Control: (1) cash
payments not subject to Section 409A of the Code; (2) cash payments subject to
Section 409A of the Code; (3) equity-based payments and acceleration; and
(4) non-cash forms of benefits; provided that all amounts or payments that are
not subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c) shall
be reduced before any amounts that are subject to calculation under Treas. Reg.
§1.280G-1, Q&A-24(b) or (c).

(c) Reduced Amount and After-Tax Receipt. For purposes hereof, the following
terms have the meanings set forth below: (i) “Reduced Amount” shall mean the
greatest amount of Payments that can be paid that would not result in the
imposition of the excise tax under Section 4999 of the Code if the Accounting
Firm determines to reduce Payments pursuant to this Section 12 and (ii) “Net
After-Tax Receipt” shall mean the present value (as determined in accordance
with Sections 280G(b)(2)(A)(ii) and 280G(d)(4) of the Code) of a Payment net of
all taxes imposed on the Eligible Employee with respect thereto under Sections 1
and 4999 of the Code and under applicable state and local laws, determined by
applying the highest marginal rate under Section 1 of the Code and under state
and local laws which applied to the Eligible Employee’s taxable income for the
immediately preceding taxable year, or such other rate(s) as the Eligible
Employee certifies, in the Eligible Employee’s sole discretion, as likely to
apply to her/him in the relevant tax year(s).

SECTION 6. WITHHOLDING

Notwithstanding anything in this Plan to the contrary, to the extent that any
acceleration hereunder results in a tax withholding obligation by an Employer,
an Eligible Employee or her/his estate or beneficiaries shall be subject to the
withholding of such amounts relating to taxes as the Employer reasonably may
determine it should withhold pursuant to any applicable

 

4

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

law or regulation. In lieu of withholding such amounts, in whole or in part, the
Employer may, in its sole discretion, accept other provisions for the payment of
taxes and any withholdings as required by law, provided that the Employer is
satisfied that all requirements of law affecting its responsibilities to
withhold compensation have been satisfied.

SECTION 7. NO DUTY TO MITIGATE

An Eligible Employee’s benefits received hereunder shall be considered severance
pay in consideration of past service, and entitlement thereto shall not be
governed by any duty to mitigate damages by seeking further employment.

SECTION 8. AMENDMENT, SUSPENSION OR TERMINATION

Prior to a Change in Control, this Plan may be amended at any time by the
Compensation Committee; provided, however, that, no amendment that negatively
impacts the benefits of an Eligible Employee that is a participant in the Plan
as of the time of such amendment shall be effective against such Eligible
Employee without the consent of such Eligible Employee.

SECTION 9. ADMINISTRATION

The Plan shall be administered by either the Compensation Committee or the
person(s) appointed by the Compensation Committee from time to time to
administer the Plan (in either case, the “Administrator”). The Administrator
shall have the power and authority to interpret the terms and provisions of the
Plan, to make all determinations it deems advisable for the administration of
the Plan, to decide all disputes arising in connection with the Plan and to
otherwise supervise the administration of the Plan. All decisions and
interpretations of the Administrator shall be binding on all persons.

SECTION 10. GOVERNING LAW

This Plan shall be governed by the laws of the United States to the extent
applicable and otherwise by the laws of the State of California, excluding the
choice of law rules thereof.

SECTION 11. SEVERABILITY

If any part of any provision of this Plan shall be invalid or unenforceable
under applicable law, such part shall be ineffective to the extent of such
invalidity or unenforceability only, without in any way affecting the remaining
parts of such provision or the remaining provisions of this Plan.

SECTION 12. DISCLAIMER OF RIGHTS

No provision in this Plan shall be construed to confer upon any individual the
right to remain in the employ or service of the Employer, or to interfere in any
way with any contractual or other right or authority of the Employer either to
increase or decrease the compensation or other benefits to any individual at any
time, to terminate any employment or other relationship between any individual
and the Employer. The obligation of the Employer to provide any benefits
pursuant to this Plan shall be interpreted as a contractual obligation to
provide only

 

5

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

those amounts described herein, in the manner and under the conditions
prescribed herein. The Plan shall in no way be interpreted to require the
Employer to transfer any amounts to a third party trustee or otherwise hold any
amounts in trust or escrow for payment to any participant or beneficiary under
the terms of the Plan.

SECTION 13. CAPTIONS

The use of captions in this Plan is for the convenience of reference only and
shall not affect the meaning of any provision of this Plan.

SECTION 14. NUMBER AND GENDER

With respect to words used in this Plan, the singular form shall include the
plural form, the masculine gender shall include the feminine gender, etc., as
the context requires.

SECTION 15. SECTION 409A

(a) Anything in this Plan to the contrary notwithstanding, if at the time of the
Eligible Employee’s “separation from service” within the meaning of Section 409A
of the Code, the Company determines that the Eligible Employee is a “specified
employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to
the extent any payment or benefit that the Eligible Employee becomes entitled to
under this Plan on account of the Eligible Employee’s separation from service
would be considered deferred compensation subject to the 20 percent additional
tax imposed pursuant to Section 409A(a) of the Code as a result of the
application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be
payable and such benefit shall not be provided until the date that is the
earlier of (A) six months and one day after the Eligible Employee’s separation
from service, or (B) the Eligible Employee’s death.

(b) The parties intend that this Plan will be administered in accordance with
Section 409A of the Code. To the extent that any provision of this Plan is
ambiguous as to its compliance with Section 409A of the Code, the provision
shall be read in such a manner so that all payments hereunder comply with
Section 409A of the Code. The parties agree that this Plan may be amended, as
reasonably requested by either party, and as may be necessary to fully comply
with Section 409A of the Code and all related rules and regulations in order to
preserve the payments and benefits provided hereunder without additional cost to
either party.

(c) To the extent that any payment or benefit described in this Plan constitutes
“non-qualified deferred compensation” under Section 409A of the Code, and to the
extent that such payment or benefit is payable upon the Eligible Employee’s
termination of employment, then such payments or benefits shall be payable only
upon the Eligible Employee’s “separation from service.” The determination of
whether and when a separation from service has occurred shall be made in
accordance with the presumptions set forth in Treasury Regulation
Section 1.409A-1(h).

(d) The Company makes no representation or warranty and shall have no liability
to the Eligible Employee or any other person if any provisions of this Plan are
determined to constitute deferred compensation subject to Section 409A of the
Code but do not satisfy an exemption from, or the conditions of, such Section.
