(c) Notwithstanding anything in the Plan to the contrary, after a Change in Control, neither the Board nor any other person shall have discretionary authority in the administration of the Plan, and any court or tribunal that adjudicates any dispute, controversy, or claim in connection with benefits under Section 5 will apply a de novo standard of review to any determinations made by the Board or the Company. Such de novo standard shall apply notwithstanding the grant of full discretion hereunder to the Board or any person or characterization of any decision by the Board or by such person as final, binding or conclusive on any party.

(a) Eligibility . The Board, in its sole discretion, may from time to time designate key executives of the Company who are eligible to participate in the Plan. The Chief Executive Officer of the Company shall be designed as a Tier I Executive and other eligible executives shall be designated by the Board as either Tier II or Tier III Executives.

(b) Participation; Execution of Participation Agreement . Each eligible executive designated by the Board pursuant to Section 4(a) shall become a Participant in the Plan only upon execution of a Participation Agreement in the form, or substantially the form, attached hereto as Appendix A , subject to additional terms as the Board may specify. Each executed Participation Agreement shall constitute the Participant’s agreement to the terms and conditions of participation in the Plan.

(a) Entitlement to Severance Benefits . In the event a Participant’s employment with the Company is terminated within 24 months after the Change in Control Date either (i) by the Company for reasons other than Cause, death, or Disability, or (ii) by the Participant for Good

Reason, the Company shall make payments and provide benefits to the Participant as specified under Sections 5(b) through 5(e), subject to the Participant’s satisfaction of the requirements of Section 6(a) (regarding waiver and release of claims) and Section 6(b) (regarding restrictive covenants). In addition, if a Participant’s employment with the Company had terminated before a Change in Control that is a “change in control event” under Treasury regulation section 1.409A-3(i)(5), and if it is reasonably demonstrated by the Participant to the Board that his or her termination of employment either was at the request of a third party that had taken steps reasonably calculated to effect the Change in Control or otherwise arose in connection with or in anticipation of the Change in Control, then, for purposes of determining entitlement to severance benefits under the Plan, the Participant’s employment is deemed to have terminated on the Change in Control Date.

(b) Lump-Sum Cash Payment . The Company shall pay to the Participant a lump-sum cash payment equal to the following applicable amount:

(i) Tier I Executive : the sum of (1) two times the sum of Base Salary plus Target Bonus and (2) the Prorated Target Bonus.

(ii) Tier II Executives : for Tier II Executives with a position of senior vice president or higher, the sum of (1) two times the sum of Base Salary plus Target Bonus and (2) the Prorated Target Bonus, and for all other Tier II Executives, two times the sum of Base Salary plus Target Bonus.

(iii) Tier III Executives : an amount to be determined at the discretion of the Board, but in no event less than four months’ Base Salary or more than one times the sum of Base Salary plus Target Bonus.

The lump-sum cash payment shall be made no later three business days following the expiration of any period during which a Participant may revoke the waiver and release of claims executed pursuant to Section 6(a), so long as that waiver and release becomes effective no later than 60 days after the Participant’s termination of employment (or the Change in Control Date, for a Participant whose termination of employment is deemed to occur on the Change in Control Date). Notwithstanding the foregoing, if the period during which a Participant has discretion to execute or revoke the waiver and release of claims straddles two taxable years of the Participant, then the Company shall make the payment in the second of such taxable years, regardless of which taxable year the Participant actually delivers the executed waiver and release to the Company.

(c) Health Benefit Continuation . The Company shall pay the premium for COBRA coverage, if elected by the Participant and his eligible dependents, upon loss of coverage under the Company’s group health plan for active employees of the Company due to termination of employment, until the earlier of (i) the date that the Participant becomes eligible for coverage under another group health plan, or (ii) for Tier I and Tier II Executives, the end of the 18-month maximum COBRA coverage period or, for Tier III Executives, the end of the 12-month period beginning on the date of termination of employment.
