Any such notice shall be deemed received on the date of receipt by the recipient thereof if received prior to 5:00 p.m. in the place of receipt and such day is a business day in the place of receipt. Otherwise, any such notice shall be deemed not to have been received until the next succeeding business day in the place of receipt.

Section 4.02 Dispute Resolution.

A party’s election to arbitrate, as herein provided, and the decision of the arbitrators in that proceeding, shall be binding on the other party. Judgment may be entered on the award of the arbitrator in any court having jurisdiction.

(b) Each party shall pay its own expenses of such arbitration or litigation and all common expenses of such arbitration or litigation shall be borne equally by Executive and the Company. Each party to an arbitration or litigation hereunder shall be responsible for the payment of its own attorneys’ fees.

Section 4.03 Unfunded Agreement. The obligations of the Company under this Agreement represent an unsecured, unfunded promise to pay benefits to Executive and/or Executive’s beneficiaries, and shall not entitle Executive or such beneficiaries to a preferential claim to any asset of the Company.

Section 4.04 Non-Exclusivity of Benefits. Unless specifically provided herein, neither the provisions of this Agreement nor the benefits provided hereunder shall reduce any amounts otherwise payable, or in any way diminish Executive’s rights as an employee of the Company, whether existing now or hereafter, under any compensation and/or benefit plans (qualified or nonqualified), programs, policies, or practices provided by the Company, for which Executive may qualify; provided, however, that the Change of Control Severance Benefits shall be in lieu of any severance benefits under any such plans, programs, policies or practices. Vested benefits or other amounts which Executive is otherwise entitled to receive under any plan, policy, practice, or program of the Company (i.e., including, but not limited to, vested benefits under any qualified or nonqualified retirement plan), at or subsequent to the Termination Date shall be payable in accordance with such plan, policy, practice, or program except as expressly modified by this Agreement.

Section 4.05 Employment Status. Nothing herein contained shall interfere with the Company’s right to terminate Executive’s employment with the Company at any time, with or without Cause, subject to the Company’s obligation to provide Change of Control Severance Benefits, if any. Executive shall also have the right to terminate Executive’s employment with the Company at any time without liability, subject only to the provisions hereof and Executive’s obligations hereunder.

Section 4.06 Mitigation. In no event shall Executive be obligated to seek other

employment or take any other action by way of mitigation of the amounts payable to Executive under any of the provisions of this Agreement nor shall the amount of any payment or benefit hereunder be reduced by any compensation earned by Executive as a result of employment by another employer.

Section 4.07 Entire Agreement. This Agreement represents the entire agreement between Executive and the Company and its affiliates with respect to Executive’s severance rights in a Change of Control situation, and supersedes all prior and contemporaneous discussions, negotiations, and agreements concerning such rights, provided, however, that any amounts payable to Executive hereunder shall be reduced by any amounts paid to Executive as required by any applicable federal, state or local law in connection with any Termination of Executive’s employment.

Section 4.08 Tax Withholding. Notwithstanding anything in this Agreement to the contrary, the Company shall withhold from any amounts payable under this Agreement all federal, state, city, or other taxes as are legally required to be withheld.

Section 4.09 Waiver of Rights. The waiver by either party of a breach of any provision of this Agreement shall not operate or be construed as a continuing waiver or as a consent to or waiver of any subsequent breach hereof

Section 4.10 Severability. In the event any provision of the Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Agreement, and the Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

Section 4.11 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without reference to principles of conflict of laws.

Section 4.12 Counterparts. This Agreement may be signed in several counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were on the same instrument.

Section 4.13 Code Section 409A. This Agreement (and the payments hereunder) are intended to qualify for the short-term deferral exception to Section 409A described in Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent possible, and to the extent they do not so qualify, they are intended to qualify for the involuntary separation pay plan exception to Section 409A described in Treasury Regulation Section 1.409A-1(b)(9)(iii) to the maximum extent possible. To the extent Section 409A is applicable to this Agreement, this Agreement is intended to comply with Section 409A. Notwithstanding any other provision of this Agreement to the contrary, this Agreement shall be interpreted, operated and administered by the Company in a manner consistent with such intentions and to avoid the pre-distribution inclusion in income of amounts payable under this Agreement and the imposition of any additional tax or interest with respect thereto. Without limiting the generality of the foregoing, if Executive is a “specified employee” within the meaning of Section 409A on the Termination Date, to the extent

required in order to comply with Section 409A, amounts that would otherwise be payable under this Agreement during the six-month period immediately following the Termination Date shall instead be paid on the first business day after the date that is six months following the Termination Date.
