Notwithstanding any provision of this Plan to the contrary, any payments and benefits provided to a Participant under this Plan, other than the Accrued Rights, shall be subject to and contingent upon (A) the Participant’s execution and delivery following the Termination Date of a separation agreement and general release of claims, each in a form reasonably satisfactory to the Company that becomes effective within forty-five (45) days following the Termination Date and (B) the Participant not revoking the foregoing release within seven (7) days after its execution and delivery to the Company.

Any Participant with an Employment Level below Vice President shall not be entitled to benefits under this Plan if the Participant rejects or fails to accept a written offer of employment from a Successor or from any Affiliate of the Company made on or before his or her Termination Date that the Company reasonably determines is for substantially comparable employment, except if the Participant rejects or fails to accept the offer for Good Reason. The Company will require any Successor that does not assume the Employer’s obligations under this Plan by operation of law to expressly assume and agree to perform this Plan in the same manner and to the same extent that the Employer would be required to perform if no such succession had taken place.

A.Withholding. The Employer may deduct and withhold from any amounts payable under this Plan such federal, state, local, foreign or other taxes as are required to be withheld pursuant to any applicable law or regulation.

B.Non-Qualified Deferred Compensation. The payments and benefits under this Plan are intended to comply with or be exempt from Section 409A and, accordingly, to the maximum extent permitted, this Plan shall be interpreted to be in compliance therewith. Notwithstanding any provision of this Plan to the contrary, in the event that the Administrator determines that any amounts payable hereunder will be immediately taxable to any Participant under Section 409A, the Administrator may (without any obligation to do so or to indemnify the Participant for failure to do so) (i) adopt such amendments to this Plan or adopt such other policies and procedures (including amendments, policies and procedures with retroactive effect) that it determines to be necessary or appropriate to preserve the intended tax treatment of the benefits provided by this Plan or the economic benefits of this Plan and (ii) take such other actions it determines to be necessary or appropriate to exempt the amounts payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder.

Notwithstanding any provision of this Plan to the contrary, no termination or other similar payments and benefits under this Plan will be payable to a Participant unless the Participant’s termination of employment constitutes a “separation from service” within the meaning of Section 409A (a “Separation from Service”).

Notwithstanding any provision of this Plan to the contrary, if a Participant is deemed by the Company at the time of the Participant’s Separation from Service to be a “specified employee” for purposes of Section 409A, to the extent delayed commencement of any portion of the benefits to which the Participant is entitled under this Plan is required in order to avoid a prohibited distribution under Section 409A, such portion of the Participant’s benefits will not be provided to the Participant prior to the earlier of (x) the expiration of the six-month period measured from the date of the Participant’s Separation from Service or (y) the date of the Participant’s death. As promptly as possible following the expiration of the applicable Section 409A period, all payments and benefits deferred pursuant to the preceding sentence will be paid in a lump sum to a Participant (or the Participant’s estate), and any remaining payments due to the Participant under this Plan will be paid as otherwise provided herein.

A Participant’s right to receive any installment payments under this Plan 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 as permitted under Section 409A.

C.Potential Reduction of Certain “Parachute Payments”.

(i)Notwithstanding any other provisions of this Plan, in the event that any payment or benefit by the Company or otherwise to or for the benefit of a Participant, whether paid or payable or distributed or distributable pursuant to the terms of this Plan (all such payments and benefits, including the payments and benefits under Section IV of the Plan, being hereinafter

referred to as the “Total Payments”), would be subject (in whole or in part) to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Total Payments shall be reduced (in the order provided in subsection B below) to the minimum extent necessary to avoid the imposition of the Excise Tax on the Total Payments, but only if (x) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income and employment taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments), is greater than or equal to (y) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income and employment taxes on such Total Payments and the amount of the Excise Tax to which the Participant would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments).

(ii)The Total Payments shall be reduced in the following order: (x) reduction on a pro-rata basis of any cash severance payments that are exempt from Section 409A, (y) reduction on a pro-rata basis of any non-cash severance payments or benefits that are exempt from Section 409A, and (z) reduction of any payments or benefits otherwise payable to the Participant on a pro-rata basis or such other manner that complies with Section 409A; provided, in case of clauses (y) and (z), that reduction of any payments attributable to the acceleration of vesting of Company equity awards shall be first applied to Company equity awards that would otherwise vest last in time.

(iii)All determinations regarding the application of this Section VII. C shall be made by an accounting firm or consulting group with experience in performing calculations regarding the applicability of Section 280G of the Code and the Excise Tax selected by the Company (the “Independent Advisors”). For purposes of determinations, no portion of the Total Payments shall be taken into account which, in the opinion of the Independent Advisors, (x) does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) or (y) constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation. The costs of obtaining such determination and all related fees and expenses (including related fees and expenses incurred in any later audit) shall be borne by the Company.

In the event it is later determined that a greater reduction in the Total Payments should have been made to implement the objective and intent of Section VII. C, the excess amount shall be returned promptly by the Participant to the Company.

A.This Plan will become effective on the Effective Date. The Board or the Administrator may amend, modify or terminate this Plan at any time; provided that, except as otherwise provided in Section VII:

(i)No amendment, modification or termination may affect any right of any Participant to claim benefits under this Plan as in effect prior to such amendment, modification or

termination with respect to a Termination Date that occurs prior to the date of such amendment, modification or termination; and

(ii)During the CIC Protection Period for a given Participant, this Plan may not be amended or modified in any manner that decreases the payments or benefits payable to the Participant or otherwise adversely affects the Participant’s economic rights or terminated.

Nothing in this Plan will prevent or limit a Participant’s continuing or future participation in any plan, practice, policy or program provided by the Company or any Affiliate thereof for which the Participant may qualify, nor will anything in this Plan limit or otherwise affect any rights the Participant may have under any contract or agreement with the Company or any Affiliate thereof. Vested benefits and other amounts a Participant is otherwise entitled to receive under any incentive compensation (including any equity award agreement), deferred compensation, retirement, pension or other plan, practice, policy or program of, or any contract or agreement with, the Company or any Affiliate thereof shall be payable in accordance with the terms of each such plan, practice, policy, program, contract or agreement, as the case may be.

All notices or other communications required or permitted by this Plan will be made in writing and all such notices or communications will be deemed to have been duly given when delivered or (unless otherwise specified) mailed by United States certified or registered mail, return receipt requested, postage prepaid, addressed as follows:

The Plan will be interpreted in accordance with its terms and their intended meanings. However, the Administrator will have the discretion to interpret or construe ambiguous, unclear, or implied (but omitted) terms in any fashion the Administrator determines to be appropriate in its reasonable discretion, and to make any findings of fact needed in the administration of the Plan. If, due to errors in drafting, any Plan provision does not accurately reflect its intended meaning, as demonstrated by consistent interpretations or other evidence of intent, or as determined by the Administrator in its reasonable discretion, the provision shall be considered ambiguous and shall be interpreted by the Administrator in a manner consistent with its intent, as determined in the reasonable discretion of the Administrator. The Administrator may amend the Plan retroactively to cure any such ambiguity.
