4.5 Settlement.

(a) Settlement Date.

As soon as reasonably practicable following the Time-Based Settlement Date and in no event later than March 15 of the calendar year following the year in which the Time-Based Settlement Date occurs, the Company shall transfer to the Participant or Permitted Transferee, in full and complete satisfaction of all of the obligations of the Company and the rights of the Participant or Permitted Transferee in respect of such Time-Based Restricted Stock Units, a number of shares of Common Stock, registered in the Participant’s or Permitted Transferee’s name, equal to the number of such vested Time-Based Restricted Stock Units that are settled on and as of the Time-Based Settlement Date.

(ii) Vested Performance-Based Restricted Stock Units shall be settled as soon as reasonably practicable following the applicable Vesting Date, and in no event later than March 15 of the calendar year following the year in which the Vesting Date occurs (the “Performance-Based Settlement Date”). Upon settlement, the Company shall transfer to the Participant or Permitted Transferee, in full and complete satisfaction of all of the obligations of the Company and the rights of the Participant in respect of such Performance-Based Restricted Stock Units, a number of shares of Common Stock, registered in the Participant’s or Permitted Transferee’s name, equal to the number of such Performance-Based Restricted Stock Units that are settled on and as of the Performance-Based Settlement Date.

(b) Conditions to Settlement.

The shares of Common Stock so issued shall be deemed to

10

be “Rollover Shares” for purposes of Section 3(b) of the Management Stockholders’ Agreement. In the event that the Participant or Permitted Transferee does not so enter into the Management Stockholders’ Agreement, if in effect at such time, the Participant or Permitted Transferee shall forfeit all vested Restricted Stock Units and the vested Restricted Stock Units shall be cancelled without any consideration therefor.

(c) Condition to Settlement; Satisfaction of Withholding Taxes.

(i) In General. Whenever shares of Common Stock are to be issued to the Participant or Permitted Transferee in settlement of vested Restricted Stock Units, the Participant or Permitted Transferee shall remit to the Company an amount in cash, by wire transfer of immediately available funds or certified check, sufficient to satisfy any applicable U.S. federal, state and local and non-U.S. tax withholding requirements.

(ii) Alternative Methods to Satisfy Withholding Taxes. The Participant or Permitted Transferee may pay up to the minimum statutory tax withholding amount due in respect of any settlement of vested Restricted Stock Units by requesting that the Company withhold shares of Common Stock that would otherwise be issued to the Participant or Permitted Transferee in connection with such settlement of vested Restricted Stock Units.

(iii) Notwithstanding the foregoing, the aggregate amount of such cash or the Fair Market Value of any shares of Common Stock withheld, in either case, as of the date of settlement of the Restricted Stock Units, must be equal to the full minimum statutory tax withholding amount payable by the Participant or Permitted Transferee in connection with such settlement. No tax amount in excess of the minimum amount required to be withheld under the applicable statutory tax provisions then in effect may be satisfied by the Participant or Permitted Transferee by having shares of Common Stock withheld. Any shares of Common Stock withheld to satisfy the Participant’s or Permitted Transferee’s minimum statutory tax withholding obligations will be valued at the Fair Market Value of such shares of Common Stock on the Settlement Date.

4.6 Administration of Restricted Stock Units.

(a) Amendment of Terms of Restricted Stock Units. The Board may, in its absolute discretion, amend the Plan or terms of any Restricted Stock Unit; provided, that any such amendment (other than a termination as provided in subparagraph (b) below) with respect to any Restricted Stock Unit outstanding at the time of such amendment shall not impair or adversely affect any Participant’s rights under the Plan or such Restricted Stock Unit without such Participant’s written consent and also provided that any such amendment shall not constitute a material modification under Section 409A of the Code.

11

(b) Termination of the Restricted Stock Units. The Board may, at any time, without amendment to the Plan or any relevant Restricted Stock Unit Grant Agreement, terminate any and all Restricted Stock Units then outstanding if the Board determines in good faith that permitting the Restricted Stock Units to remain outstanding would violate any law or regulation or require the Company to register its securities under the Securities Act or file reports under the Exchange Act if at such time the Company is not required to do so, provided, however, that such termination shall be in accordance with the applicable provisions of Section 1.409A-3(j)(4)(ix) of the Code, and provided, further, that the Company, in full consideration of such termination, shall pay to Participants either (i) an amount in cash equal to the Fair Market Value of a share of Common Stock multiplied by the number of Restricted Stock Units which are vested as of such time, as determined by the Board as of the date on which the Restricted Stock Units are terminated, or (ii) the number of shares of Common Stock which equals the number of Restricted Stock Units which are vested at such time. Such payment shall be made as soon as practicable following such termination.

(c) Termination of this Plan. The Board may at any time, in its absolute discretion, suspend or terminate this Plan. No awards may be granted during any suspension of the Plan or after the Plan has been terminated. The termination of the Plan shall not affect any previous Grants until the date on which all Restricted Stock Units eligible to vest are settled, at which time all unvested Restricted Stock Units will be cancelled, provided, however, that the Board may determine in its sole discretion that upon or following such termination, some or all outstanding Restricted Stock Units shall become vested. After the Plan terminates, the function of the Board with respect to the Plan will be limited to supervising the administration of previous Grants.

4.7 Adjustment upon Changes in Company Common Stock.

(a) Increase or Decrease in Shares of Common Stock Without Consideration.

(ii) cancel, effective immediately prior to the occurrence of such event, any Restricted Stock Unit outstanding immediately prior to such event (whether or not then vested), and in full consideration of such cancellation, pay to each Participant to whom such Restricted Stock Unit was granted an amount in cash, for each share of Common Stock subject to such Restricted Stock Unit, equal to the product of (1) the value of securities and property (including cash) per share of Common Stock received by the stockholders of the Company as a result of such event, as determined by the Board in its absolute discretion and (2) the number of Restricted Stock Units so cancelled that were held by such Participant; provided, however, that with respect to any Restricted Stock Unit that is deferred compensation subject to Section 409A of the Code, the Board may provide for such cancellation and payment only in the event that either (x) the transaction referred to in subsection (c)(1)-(4) above is a “change in control” as defined in Section 409A of the Code or (y) such cancellation and payment is made in accordance with the applicable provisions of Section 1.409A-3(j)(4)(ix) of the Code; or

13

(e) Other Changes. In the event of any change in the capitalization of the Company or a corporate change other than those specifically referred to in Sections 4.7 (a), (b), (c) or (d) hereof, or in the event a Public Market exists for the securities subject to Restricted Stock Units, the Board shall, in its absolute discretion, make such adjustments in the number shares of Common Stock subject to Restricted Stock Units outstanding on the date on which such change occurs and, if applicable, in the Fair Market Value of each such Restricted Stock Unit, as the Board may, in its absolute discretion, consider appropriate to prevent dilution or enlargement of rights.

(f) No Other Rights. Except as expressly provided in the Plan or the Restricted Stock Unit Grant Agreements evidencing the Restricted Stock Units, no Participant shall have any rights by reason of (i) any subdivision or consolidation of the shares of Common Stock or any other securities of any class, (ii) the payment of any distribution, (iii) any increase or decrease in the number of shares of Common Stock or (iv) any dissolution, liquidation, merger or consolidation of the Company or any other corporation.
