(b) Participation. An eligible Employee may elect to participate in the Plan with respect to any Deferral Period by submitting a Participation Agreement to the Administrator by the last business day immediately preceding the applicable Deferral Period. With respect to RSUs, an eligible Employee also may elect to participate in the Plan by submitting a Participation Agreement to the Administrator by the last business day immediately preceding the applicable one-year vesting period for one or more portions of the RSU award, provided such vesting periods are at least thirteen (13) months after the date of the initial RSU award.

6

provided that the notice is filed with the administrator before the Bonus or Cash LTIP, as applicable, has become “readily ascertainable” (within the meaning of Section 409A), the change in the dollar amount or percentage of Compensation to be deferred will be effective on the date the change is filed with the Administrator.

The Administrator may, from time to time, employ agents and delegate to them such administrative duties as it sees fit, and may from time to time consult with legal counsel who may be counsel to the Corporation. The Administrator shall have no power to add to, subtract from or modify any of the terms of the Plan, or to change or add to any benefits provided under the Plan, or to waive or fail to apply any requirements of eligibility for a benefit under the Plan. No member of the Administrator shall act in respect of his or her own Account. All decisions and determinations by the Administrator shall be final and binding on all parties. All decisions of the Administrator shall be made by the vote of the majority, including actions in writing taken without a meeting. All elections, notices and directions under the Plan by a Participant shall be made on such forms as the Administrator shall prescribe.

Section 7.2. Plan Administrator. The Corporation shall be the “administrator” under the Plan for purposes of ERISA.

Section 7.3. Amendment, Termination and Withdrawal.

(a) In General. The Plan may be amended from time to time or may be terminated at any time by the Board. Except as provided in Section 7.3(b), no amendment or termination of the Plan, however, may adversely affect the amount or timing of payment of any person’s benefits

13

accrued under the Plan to the date of amendment or termination without such person’s written consent.

(b) Compliance with Section 409A. (1) It is intended that the Plan comply with the provisions of Section 409 A, so that the income inclusion provisions of Section 409A do not apply to the Participants. The Plan and each Participation Agreement and Deferral Commitment shall be administered in a manner consistent with this intent.

(2) Neither a Participant nor any of a Participant’s creditors or beneficiaries shall have the right to subject any deferred compensation (within the meaning of Section 409A of the Code) payable under the Plan to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted under Section 409A, any deferred compensation (within the meaning of Section 409A) payable to a Participant or for a Participant’s benefit under the Plan and grants hereunder may not be reduced by, or offset against, any amount owing by a Participant to the Corporation or any of its affiliates.

(3) Notwithstanding any provision of the Plan and Participation Agreements and Deferral Commitments to the continually, in light of the uncertainty with respect to the proper application of Section 409A, Holdings reserves the right to make amendments to the Plan and Participation Agreements and Deferral Commitments as Holdings deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A. In any case, a Participant shall be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on a Participant or for a Participant’s Account in connection with the Plan (including any taxes and penalties under Section 409A), and neither Holdings, the Corporation nor any of their affiliates shall have any obligation to indemnify or otherwise hold a Participant harmless from any or all of such taxes or penalties.

Section 7.4. Successors. The Corporation shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all of the business and/or assets of the Corporation expressly to assume and to agree to perform this Plan in the same manner and to the same extent the Corporation would be required to perform if no such succession had taken place. This Plan shall be binding upon and inure to the benefit of the Corporation and any successor of or to the Corporation, including without limitation any persons acquiring directly or indirectly all or substantially all of the business and/or assets of the Corporation whether by sale, merger, consolidation, reorganization or otherwise (and such successor shall thereafter be deemed the “Corporation” for the purposes of this Plan), and the heirs, beneficiaries, executors and administrators of each Participant.

Section 7.5. Claims Procedure.

(a) Except as otherwise provided in the Plan, the Administrator will determine the rights of any Participant to any benefits hereunder. Any employee or former employee of the Corporation who believes that he has not received any benefit under the Plan to which he believes he is entitled, may file a claim in writing with the Administrator. The Administrator will, no later than ninety (90) days after the receipt of a claim, either allow or deny the claim by written notice to the claimant: provided, however, that if the Administrator determines that special circumstances require an extension of time for processing of an employee’s claim, the

14

Administrator will provide written notice of the extension to the employee within such ninety (90)-day period. In no event will the extension of time to process the claim exceed a period of ninety (90) days from the end of the initial ninety (90)-day review period. If a claimant does not receive written notice of the Administrator’s decision on his or her claim within the first ninety (90)-day review period (or the one-hundred and eighty (180)-day review period, in the case of special circumstances as determined by the Administrator), the claim will be deemed to have been denied in full.

(b) A denial of a claim by the Administrator, wholly or partially, will be written in a manner calculated to be understood by the claimant and will include:

(i) the specific reason or reasons for the adverse determination;

(ii) specific reference to pertinent Plan provisions on which the denial is based;

(iii) a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary; and

(iv) an explanation of the claim review procedure and the time limits applicable to such procedures, including a statement of a claimant’s right to bring a civil action under ERISA following an adverse benefit determination on review.

(c) A claimant whose claim is denied (or his duly authorized representative) may, within sixty (60) days after receipt of denial of his or her claim, request a review of such denial by the Committee by filing with the Secretary of the Committee a written request for review of his or her claim. If the claimant does not file a request for review with the Committee within such sixty (60)-day period, the claimant will be deemed to have acquiesced in the original decision of the Committee on his or her claim. If a written request for review is so filed within such sixty (60)-day period, the Committee will conduct a full and fair review of such claim. During such full review, the claimant will be given the opportunity to, upon request and free of charge, obtain reasonable access to and copies of all documents, records and other information that are pertinent to his or her claim and to submit issues and comments in writing. The Committee will notify the claimant of its decision on review within sixty (60) days after receipt of a request for review: provided, however, that if the Committee determines that special circumstances require an extension of time for processing of an employee’s claim, the Committee will provide written notice of the extension to the employee within such sixty (60) day review period. In no event will the extension of time to process the claim exceed a period of sixty (60) days from the end of the initial sixty (60)-day review period. If a claimant does not receive written notice of the Committee’s decision on his or her claim within the first sixty (60) day review period (or the one-hundred and eighty (180)-day review period, in the case of special circumstances as determined by the Committee), the claim will be deemed to have been denied on review. Notice of the decision on review will be in writing.

Section 7.6. Expenses. All expenses of the Plan shall be paid by the Corporation from funds other than those deemed Investment Funds as provided in Section 5.3, except that brokerage

15

commissions and other transaction fees and expenses relating to the investment of deemed assets and investment fees attributable to commingled investment of such assets shall be paid from or charged to such assets or earnings thereon.
