4

(j)                                    Executive acknowledges and agrees that Executive received and reviewed a copy of the Securityholders Agreement and the LLC Agreement and that the Incentive Units are subject to the terms and conditions of the Securityholders Agreement and the LLC Agreement.

(k)                                 The Company has advised Executive that a notation in the form set forth below and the legends set forth in Section 9.2 of the Securityholders Agreement shall be placed in the appropriate records of the Company indicating that the Units are subject to restrictions on transfer (and if the Company should at some time in the future engage the services of a securities transfer agent, appropriate stop-transfer instructions will be issued to such transfer agent with respect to the Incentive Units):

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN REPURCHASE OPTIONS AND OTHER PROVISIONS SET FORTH IN AN INCENTIVE UNIT GRANT AGREEMENT BETWEEN THE ISSUER AND DANIEL E.

5.4.                            Binding Effect.  The provisions of this Agreement shall be binding upon and accrue to the benefit of the parties hereto and their respective heirs, legal representatives, successors and permitted assigns; provided, however, that no Permitted Transferee shall derive any rights under this Agreement unless and until such Permitted Transferee has executed and delivered to the Company a valid undertaking and becomes bound by the terms of this Agreement, the LLC Agreement and the Securityholders Agreement; provided further that Vestar Capital Partners V, L.P., a Cayman Islands exempted limited partnership, is a third party beneficiary of the

5.6.                            Governing Law.  This Agreement and all disputes of the parties relating to the entering into and performance under this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware without reference to its conflict of laws principles that would require the application of the laws of another jurisdiction.

5.9.                            Integration.  This Agreement and the documents referred to herein or delivered pursuant hereto (including, without limitation, the LLC Agreement and the Securityholders Agreement) contain the entire understanding of the parties with respect to the subject matter hereof and thereof.  There are no restrictions, agreements, promises, representations, warranties, covenants or undertakings with respect to the subject matter hereof other than those expressly set forth herein and therein.  This Agreement and the documents referred to herein or delivered pursuant hereto (including, without limitation, the LLC Agreement and the Securityholders Agreement) supersede and cancel all prior and contemporaneous agreements and understandings between the parties with respect to such subject matter.  The parties hereby agree and acknowledge that, other than as provided or referenced herein (including the Class E Unit Grant), Executive holds no other incentive equity units in the Company, and to the extent incentive equity units were granted previously, Executive hereby forfeits any and all such incentive equity units, for no consideration and without the need for any further action by either party.

7

injuries precisely and that, in the event of such a breach or threat thereof, each party hereto shall be entitled to seek a temporary restraining order and/or preliminary or permanent injunction restraining the other party (and their Permitted Transferees) from engaging in activities prohibited by this Agreement or such other relief as may be required specifically to enforce any of the terms hereof.  If for any reason it is held that the restrictions under this Agreement are not reasonable or that consideration therefore is inadequate, such restrictions shall be interpreted or modified to include as much of the duration and scope identified in this Agreement as will render such restrictions valid and enforceable.

5.12.                     WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

5.14.                     Spousal Consent.  If Executive is lawfully married as of the date hereof, Executive’s spouse shall execute and deliver to the Company the Consent in the form of Exhibit C attached hereto.

5.15.                     Taxes. The Company or its subsidiaries shall be entitled to deduct or withhold from any cash amounts owing to Executive any taxes imposed with respect to Executive’s compensation or other payments from the Company or its subsidiaries or Executive’s ownership interest in the Company, including wages, bonuses and/or cash distributions. To the extent that such amounts are insufficient to permit the Company or its subsidiaries to satisfy withholding obligations solely with respect to such taxes arising from Executive’s compensation or other payments from the Company or its subsidiaries, Executive shall indemnify the Company and its subsidiaries for any amounts paid with respect to any such taxes, together with any interest, penalties and related expenses thereto.

5.16.                     Survival. All covenants, representations and warranties contained herein or made in writing by any party in connection herewith shall survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby. This Agreement shall survive Executive’s termination of employment or service and shall remain in full force and effect after such termination.

5.17.                     Deemed Transfer of Executive Securities.

8

holding such forfeited units shall no longer have any rights as a holder of such units and such units shall be deemed forfeited in accordance with the applicable provisions hereof and thereof and the Company shall be deemed the owner and holder of such units, whether or not the certificates therefor, if any, have been delivered.

6.                                      Joinder to LLC Agreement and Securityholders Agreement.  If Executive is not already a party to the LLC Agreement and the Securityholders Agreement, then by virtue of the grant of the Incentive Units and Executive’s execution of this Agreement, Executive hereby joins and becomes a party to, and the Company hereby accepts Executive as a party to, each of the LLC Agreement as a Management Member and the Securityholders Agreement as an Other Holder.  The Company and Executive each acknowledges and agrees that Executive shall be entitled to the applicable benefits, and shall be subject to the applicable obligations under the LLC Agreement and the Securityholders Agreement.  In the event that Executive fails to timely comply with any of Executive’s obligations under the LLC Agreement or Securityholders Agreement as determined by the Board in its good-faith discretion, Executive may be required to immediately forfeit any or all of the Incentive Units outstanding at the time of such non-compliance without any consideration being paid therefor.  By virtue of the grant of the Incentive Units and Executive’s execution of this Agreement, Executive shall be deemed to have granted Executive’s perpetual and irrevocable power of attorney to the Company, with full right, power and authority to take all actions necessary and/or desirable on behalf of Executive to effectuate the provisions of the LLC Agreement and Securityholders Agreement with respect to all Incentive Units owned by Executive and acquired by Executive hereunder.  If Executive is already a party to the LLC Agreement, then, by virtue of the grant of the Units hereunder and Executive’s execution of this Agreement, Executive hereby consents to the terms and conditions set forth in the LLC Agreement and hereby joins and becomes a party to the LLC Agreement.
