6.2          This Plan, and all awards made hereunder, may be amended or modified upon the approval of the Compensation Committee, provided that no such amendment or modification shall be effective with respect to any Participant or any Participant’s Retention Agreement if such amendment or modification is adverse to such Participant unless such Participant consents in writing to such modification or amendment.

Section 7.                                          General.

7.1          This Plan and the granting of Retention Payments, as well as the other obligations of the Company under this Plan, shall be subject to, and is intended to comply with, all applicable federal and state laws, rules and regulations.  The place and administration of this Plan shall be conclusively deemed to be within the Commonwealth of Pennsylvania and the validity, construction, interpretation, administration and effect of this Plan, and the rights of any and all Persons having or claiming to have an interest therein or thereunder shall be governed by, and determined exclusively and solely in accordance with, the laws of the Commonwealth of Pennsylvania, to the extent not superseded by applicable federal law.  If any provisions of this Plan shall be held unlawful or otherwise invalid or unenforceable in whole or in part, the unlawfulness, invalidity or unenforceability shall not affect any other provisions of this Plan or part thereof, each of which shall remain in full force and effect.

7.2          Notwithstanding any provision herein to the contrary, no provision in this Plan or in the Retention Agreement shall be interpreted to obligate the Company to retain a Participant in its employ for any period of time or to interfere with or limit in any way the right of the Company to terminate such Participant’s employment.  Nothing contained in this Plan and no action taken pursuant to the provisions of this Plan shall create or be considered to create a trust or fund of any kind or fiduciary relationship between the Company or any successor employer or any of its affiliates and any Participant or any of its other employees or a security interest of any kind in any property of the Company or any successor employer or any of its affiliates in favor of any Participant herein or any other Person.

7.3          The Company shall withhold from any amount payable hereunder to a Participant such amount as shall be sufficient to satisfy all Federal, state, local, and foreign withholding tax requirements relating thereto.

7.4          No Participant or any other party claiming an interest in amounts earned under the Plan shall have any interest whatsoever in any specific asset of the Company.  To the extent that any party acquires a right to receive payments under the Plan, such right shall be equivalent to that of an unsecured general creditor of the Company.

7.5          Participants will not be eligible to accelerate or defer payments of Retention Payments under this Plan for any reason.

7.6          It is intended that payments under this Plan meet the short-term deferral exception under Internal Revenue Code Section 409A (including, but not limited to, any future

5

amendments to Code section 409A, and any other Internal Revenue Service (“IRS”) or other governmental rulings, regulations or interpretations (collectively, “Section 409A”)).  If not exempt, the payments and benefits payable pursuant to this Plan and any Retention Agreement are intended to comply with Section 409A, to the extent the requirements of Section 409A are applicable hereto, and the provisions of this Plan and any Retention Agreement shall be construed and administered in a manner consistent with that intention. In furtherance thereof, if payment or provision of any amount or benefit hereunder that is subject to Section 409A at the time specified herein would subject such amount or benefit to any additional tax under Section 409A, the payment or provision of such amount or benefit shall be postponed to the earliest commencement date on which the payment or provision of such amount or benefit could be made without incurring such additional tax.  In addition, to the extent that any IRS guidance issued under Section 409A would result in the Participant being subject to the payment of interest or any additional tax under Section 409A, the Company shall, to the extent reasonably possible and as allowed by applicable treasury regulations, amend this Plan in order to avoid the imposition of any such interest or additional tax under Section 409A, which amendment shall have the minimum economic effect necessary and be reasonably determined in good faith by the Company.  Without limiting the foregoing, the terms “terminates” or “termination of employment” or similar terms used in this Plan shall be interpreted to mean to occur when a “separation of service” occurs as defined under Section 409A.
