7.2 Investment Earnings.

(a) The Participant shall designate, at a time and in a manner acceptable to the Plan Administrator, one or more Investment Funds for his or her Account for the sole purpose of determining the deemed earnings to be credited or debited to such Account. A Participant may change the Investment Fund election applicable to the Participant’s Account and may reallocate the balance in each Investment Fund among the other available Investment Funds, in accordance with procedures established by the Plan Administrator. Notwithstanding the foregoing, the Participant’s Account balance may be reduced by any applicable investment fees, including fees imposed upon a Participant’s reallocation of his or her investment allocations.

Upon any change in the Investment Funds, each Participant shall have the opportunity to select among such new Investment Funds as are designated by the Plan Administrator. In case of failure to elect such new Investment Funds, the Participant shall be deemed to have made an election to invest his or her Account in the investment options then being offered that are most comparable to the Participant’s old investment options. The decision of comparable investment options shall be made in the sole discretion of the Plan Administrator.

7.3 Nature of Accounts. Accounts may not actually be invested in the Investment Funds and Participants do not have any real or beneficial ownership in the Investment Funds prior to a Payment Event. A Participant’s Account is solely a device for the measurement and determination of the amounts to be paid to the Participant pursuant to the Plan and shall not constitute or be treated as a trust fund of any kind.

Each Participant shall be provided with statements or access to statements setting out the amounts in his or her Account(s), which shall be delivered or made available at such intervals determined by the Plan Administrator, and shall reflect the value of the Account balance on the applicable valuation date.

7.5 Ownership of Amounts. The Company may, but shall not be required, to establish and maintain a trust to provide a convenient method of setting aside sufficient assets to meet some or all of its future obligations under the Plan. All property and rights purchased with amounts set aside in the fund and all income attributable to such amounts, property, or rights, shall remain (until paid to the Participant or Beneficiary) solely the property of the Company, and subject only to the claims of the Company’s general creditors. The obligation of the Company to make payments pursuant to the Plan is contractual only, and neither the Participant nor any Beneficiary shall have a preferred claim or lien on or to any assets of the trust but shall have only the right to receive the benefits payable under the Plan.

9.7 Timing of Valuation. The value of a Participant’s Account for distribution shall be determined as of the applicable Payment Event. Notwithstanding the foregoing, if a Participant elects installment payments under Section 9.2, the first annual installment payment in a series of installment payments shall be equal to (a) the value of the Participant’s Account (or relevant portion thereof) on the date of distribution of the first installment payment, divided by (b) the number of installment payments elected by the Participant.

10.2 Without limiting Section 10.1, the Plan Administrator may accelerate distribution of a Participant’s vested Account to the extent that (a) the aggregate amount in the Participant’s Account does not exceed the applicable dollar amount under Section 402(g)(1)(B) of the Code, (b) the distribution results in the termination of the Participant’s entire interest in the Plan and any plans that are aggregated with the Plan pursuant to Treas. Reg. Section 1.409A-1(c)(2), and (c) the Plan Administrator’s decision to cash out the Participant’s Account is evidenced in writing no later than the date of distribution.

11. Plan Administration.

11.1 Administration By Plan Administrator. The Plan shall be administered by the Plan Administrator, which shall have the authority to:

(a) construe and interpret the Plan and apply its provisions;

(b) promulgate, amend, and rescind rules and regulations relating to the administration of the Plan;

(c) authorize any person to execute, on behalf of the Company, any instrument required to carry out the purposes of the Plan;

(d) determine minimum or maximum amounts, and the types of compensation, that Participants may elect to defer under the Plan;

(e) determine the amount of any Excess NQ Match and Excess NQ RSA Contributions with respect to any Plan Year, in accordance with the terms of the Plan;

(f) select, subject to the limitations set forth in the Plan, those Employees who shall be Eligible Employees and Eligible Executives;

(g) calculate deemed earnings and losses on Accounts;

(h) interpret, administer, reconcile any inconsistency in, correct any defect in, and/or supply any omission in the Plan and any instrument, Deferral Election, or agreement relating to the Plan; and

(i) exercise discretion to make any and all other determinations which it determines to be necessary or advisable for the administration of the Plan.

11.2 Non-Uniform Treatment. The Plan Administrator’s determinations under the Plan need not be uniform and any such determinations may be made selectively among Participants. Without limiting the generality of the foregoing, the Plan Administrator shall be entitled, among other things, to make non-uniform and selective determinations with regard to: (a) the terms or conditions of any Elective Deferral; or (b) the amount, terms, or conditions of any Excess NQ Match or Excess NQ RSA Contribution, in accordance with the Plan terms.

11.3 Plan Administrator Decisions Final. Subject to Section 14, all decisions made by the Plan Administrator pursuant to the provisions of the Plan shall be final and binding on the Company and the Participants and Beneficiaries, unless such decisions are determined by a court having jurisdiction to be arbitrary and capricious.

11.4 Indemnification. Neither the Plan Administrator nor any designee shall be liable for any action, failure to act, determination, or interpretation made in good faith with respect to the Plan except for any liability arising from his or her own wilful malfeasance, gross negligence, or reckless disregard of his or her duties.

9

12. Amendment and Termination. Subject to the applicable requirements of Section 409A of the Code, the Board, or any committee designated by the Board, may, at any time, and in its discretion, alter, amend, modify, suspend, or terminate the Plan or any portion thereof, provided, however, that no such alteration, amendment, modification, suspension, or termination shall, without the consent of a Participant, reduce the amounts credited to the Participant’s Account as of such date.

13. Miscellaneous.

13.1 No Employment or Other Service Rights. Nothing in the Plan or any instrument executed pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate or interfere in any way with the right of the Company or any Affiliate to terminate the Participant’s employment or service at any time with or without notice and with or without cause.

13.2 Tax Withholding. The Company and its Affiliates shall have the right to deduct from any amounts otherwise payable under the Plan any federal, state, local, or other applicable taxes required to be withheld.

13.3 Governing Law. The Plan shall be administered, construed, and governed in all respects under and by the laws of the State of New York, without reference to the principles of conflicts of law (except and to the extent pre-empted by applicable Federal law).

13.4 Section 409A of the Code.

(a) The Company intends that the Plan comply with the requirements of Section 409A of the Code and shall be operated and interpreted consistent with that intent. Notwithstanding anything in the Plan to the contrary, distributions may only be made under the Plan upon an event and in a manner permitted by Section 409A of the Code. In no event shall a Participant, directly or indirectly, designate the calendar year of payment, except as permitted by Section 409A of the Code.

(b) Notwithstanding anything in the Plan to the contrary, if a Participant’s distribution is to be paid upon separation from service, payment of the distribution shall be delayed for a period of six months after the Participant’s separation from service, if the Participant is a “specified employee” as defined under Section 409A of the Code (as determined by the Plan Administrator) and if required pursuant to Section 409A of the Code (“six-month delay”). If payment is delayed, the Participant’s distribution shall be paid within 30 days of the date that is the six-month anniversary of the Participant’s separation from service, or death if earlier.

(c) Notwithstanding the foregoing, the Company makes no representation that the Plan complies with Section 409A of the Code and shall have no liability to any Participant or Beneficiary for any failure to comply with Section 409A of the Code.

(d) This Plan shall constitute an “account balance plan” as defined in Treasury Regulation Section 31.3121(v)(2)-1(c)(1)(ii)(A). For purposes of Section 409A of the Code, all amounts deferred under this Plan shall be aggregated with amounts deferred under other account balance plans.

13.5 No Warranties. Neither the Company nor the Plan Administrator warrants or represents that the value of any Participant’s Account will increase. Each Participant assumes the risk in connection with the deemed investment of his or her Account.

13.6 Beneficiary Designation. Each Participant under the Plan may from time to time name any beneficiary or beneficiaries to receive the Participant’s interest in the Plan in the event of the Participant’s death. Each designation will revoke all prior designations by the same Participant, shall be in a form reasonably prescribed by the Plan Administrator, and shall be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. If a Participant fails to designate a beneficiary, then the Participant’s designated beneficiary shall be deemed to be the Participant’s estate.

13.7 No Assignment. Neither a Participant nor any other person shall have any right to sell, assign, transfer, pledge, anticipate, or otherwise encumber, transfer, hypothecate, or convey any amounts payable hereunder prior to the date that such amounts are paid (except for the designation of beneficiaries pursuant to Section 13.6).

13.8 Expenses. The costs of administering the Plan shall be charged to Participant Accounts, unless paid for by the Company, as determined by the Company in its discretion.

10

13.9 Severability. If any provision of the Plan is held to be invalid, illegal, or unenforceable, whether in whole or in part, such provision shall be deemed modified to the extent of such invalidity, illegality, or unenforceability and the remaining provisions shall not be affected.

13.10 Headings and Subheadings. Headings and subheadings in the Plan are for convenience only and are not to be considered in the construction of the provisions hereof.

14. Claims Procedures.

If the Plan Administrator determines that an extension of time for processing is required, the Plan Administrator shall furnish written or electronic notice of the extension to the Claimant before the end of the initial 90 day period. Any notice of extension shall describe the special circumstances necessitating the additional time and the date by which the Plan Administrator expects to render its decision.

14.3 Notice of Denial. If the Plan Administrator denies the claim, it must provide to the Claimant, in writing or by electronic communication, a notice which includes:

14.4 Appeal Procedures. A request for appeal of a denied claim must be made in writing to the Plan Administrator within 60 days after receiving notice of denial. The decision on appeal will be made within 60 days after the Plan Administrator’s receipt of a request for appeal, unless special circumstances require an extension of time for processing, in which case a decision will be rendered not later than 120 days after receipt of a request for appeal. A notice of such an extension must be provided to the Claimant within the initial 60 day period and must explain the special circumstances and provide an expected date of decision. The reviewer shall afford the Claimant an opportunity to review and receive, without charge, all relevant documents, information and records and to submit issues and comments in writing to the Plan Administrator. The reviewer shall take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim regardless of whether the information was submitted or considered in the initial benefit determination.

(a) The specific reason(s) for the denial;

(b) Specific references to the pertinent Plan provisions on which such denial is based;

(c) A statement that the Claimant may receive on request all relevant records at no charge;

(f) If an internal rule was relied on to make the decision, either a copy of the internal rule or a statement that this information is available at no charge upon request.

14.6 Claims Procedures Mandatory. The internal claims procedures set forth in this Section 14 are mandatory.
