The Plan shall be interpreted, administered and operated by the Committee (the “Plan Administrator”), which shall have complete authority, subject to the express provisions of the Plan, to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, and to make all other determinations necessary or advisable for the administration of the Plan. All decisions, interpretations and other actions of the Plan Administrator shall be final, conclusive and binding on all parties who have an interest in the Plan. Notwithstanding the foregoing, the Plan Administrator or, with respect to a Participant who is not an executive officer or Senior Vice President of the Company, the Company’s Chief Executive Officer, shall determine the Participants and the size of such Participant’s Retention Bonus (as defined below) in accordance with the provisions of Section 4 hereof. Promptly following such determination, the Company shall provide written notice to each Participant pursuant to a Participation Notice.

4.       Retention Bonus.

In order to be eligible to receive a Retention Bonus, a Participant must be continuously employed by the Company (including a Successor Entity or an Affiliate) through the applicable vesting date.

The Retention Bonus shall be payable within 30 days following the Participant’s termination date.

6.       Payment. Retention Bonus payments shall be made by the designated payroll provider within 30 days following the applicable vesting date.

7.       Section 409A.

7.1               To the extent applicable, the Plan shall be interpreted and applied consistent and in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of the Plan to the contrary, to the extent that the Plan Administrator determines that any payments or benefits under the Plan may not be either compliant with or exempt from Section 409A of the Code and related Department of Treasury guidance, the Plan Administrator may in its sole discretion adopt such amendments to the Plan or take such other actions that the Plan Administrator determines are necessary or appropriate to (i) exempt the compensation and benefits payable under the Plan from Section 409A of the Code and/or preserve the intended tax treatment of such compensation and benefits, or (ii) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance; provided, however, that this Section 7 shall not create any obligation on the part of the Plan Administrator to adopt any such amendment or take any other action, nor shall the Company or any of its Affiliates have any liability for failing to do so.

7.2               Any right to a series of installment payments pursuant to this Plan and any Participation Notice is to be treated as a right to a series of separate payments. To the extent permitted under Section 409A of the Code, any separate payment or benefit under this Plan and any Participation Notice or otherwise shall not be deemed “nonqualified deferred compensation” subject to Section 409A to the extent provided in the exceptions in Treasury Regulation Section 1.409A-1(b)(4), Section 1.409A-1(b)(9) or any other applicable exception or provision of Section 409A of the Code. All payments of nonqualified deferred compensation subject to Section 409A of the Code to be made hereunder upon a termination of employment may only be made upon the Participant’s Separation from Service.

7.3               Notwithstanding anything to the contrary herein, no portion of a Participant’s Retention Bonus shall be paid to any Participant during the six-month period following such Participant’s Separation from Service if the Company reasonably determines that paying such amounts at the time or times indicated herein would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six-month period (or such earlier date upon which such amount can be paid under Section 409A of the Code without resulting in a prohibited distribution, including as a result of the applicable Participant’s death), the Participant shall be paid a lump-sum amount equal to the cumulative amount that would have otherwise been payable to the Participant during such period (without interest).

8.        Successors.

8.1               Company Successors. The Plan shall inure to the benefit of and shall be binding upon the Company, the Successor Entity, and their successors and assigns. Any successor (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets shall assume and agree to perform the obligations of the Company under the Plan.

8.2               Participant Successors. The Plan shall inure to the benefit of and be enforceable by each Participant’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees, legatees or other beneficiaries. If a Participant dies while any amount remains payable to such Participant hereunder, all such amounts shall be paid in accordance with the terms of the Plan to the executors, personal representatives or administrators of such Participant’s estate.

9.        Miscellaneous.

9.1               Entire Plan. The Plan contains the entire understanding of the parties relating to the subject matter hereof.

9.2               No Right to Continued Service. Nothing contained in the Plan shall (i) confer upon any Participant any right to continue as an Employee of the Company or any Successor Entity, or any Affiliate thereof, (ii) constitute any contract of employment or agreement to continue employment for any particular period, or (iii) interfere in any way with the right of the Company or any Successor Entity, or any Affiliate thereof, to terminate a service relationship with any Participant, with or without Cause.

9.3               Termination and Amendment of Plan. If a Change in Control is not consummated prior to the two-year anniversary of the Effective Date, then (i) the Plan shall terminate automatically and (ii) no Retention Bonus shall become payable pursuant to the Plan. In addition, the Plan shall terminate upon the Company’s satisfaction of all of its obligations under the Plan. The Company reserves the right to amend or modify the Plan or any Participation Notice at any time in its sole discretion prior to the Closing. The Plan shall not be amended, modified, suspended or terminated on or after the Closing (a) except with the express written consent of each Participant who would be adversely affected by any such amendment, modification, suspension or termination, or (b) unless and until all rights and obligations hereunder have been fully and finally satisfied or forfeited. In addition, following the Closing, the definition of Cause and/or Good Reason (if applicable) set forth in an applicable employment agreement, service agreement, retention or severance agreement, or other similar agreement between a Participant and the Company (or an Affiliate) shall not be amended or modified except with the express written consent of each Participant who would be adversely affected by any such amendment or modification.

9.4               Payments Not Deemed to be Salary; No ERISA Plan. No payment payable under the Plan shall be deemed salary or other compensation to any Participant for purposes of computing benefits to which a Participant may be entitled under any vacation, disability, profit sharing, pension plan or other arrangement of the Company for the benefit of employees except as may otherwise be specifically provided for by such plan or other arrangement. This Plan is intended to constitute an “unfunded” plan for incentive compensation, and is not intended to constitute a plan subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended. Nothing contained in the Plan and no action taken pursuant to the provisions of the Plan shall create or be considered to create a trust or fund, or any obligation to fund or otherwise secure the payment of any amounts due under the Plan, or any kind or fiduciary relationship between the Company and any Participant or any of its other employees or a security interest of any kind in any property of the Company in favor of any Participant or any other person.

9.5               Withholding. The Company shall have the authority and the right to deduct and withhold an amount sufficient to satisfy federal, state, local and foreign taxes required by law to be withheld with respect to any Retention Bonus payable under the Plan.

9.6               Benefits not Assignable. Except as otherwise provided herein or by law, no right or interest of any Participant under the Plan shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation by execution, levy, garnishment, attachment, pledge or in any manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of any Participant under the Plan shall be liable for, or subject to, any obligation or liability of such Participant. When a payment is due under the Plan to a Participant who is unable to care for his or her affairs, payment may be made directly to his or her legal guardian or personal representative.

9.7               Restrictive Covenants. A Participant’s entitlement to and retention of the amounts under the Plan are expressly conditioned upon such Participant’s continued compliance with applicable restrictive covenants signed or entered into in connection with such Participant’s employment (including but not limited to, covenants relating to competition, solicitation or hiring of employees, solicitation of customers, and confidentiality), and if the Participant breaches any such restrictive covenants then amounts described herein shall no longer be payable and, if already paid, shall promptly be returned to the Company within seven days of the Company providing the Participant with written notice of such breach, to the extent permitted or required by law.

9.8               Applicable Law. The Plan shall be construed, interpreted and the rights of the parties determined in accordance with the laws of the State of Delaware (without regard to conflict of law principles that would result in the application of any law other than the law of the State of Delaware).

9.9               Validity. The invalidity or unenforceability of any provision of the Plan shall not affect the validity or enforceability of any other provision of the Plan, which shall remain in full force and effect.

9.10           Captions. The captions contained in the Plan are for convenience only and shall have no bearing on the meaning, construction or interpretation of the Plan’s provisions.
