11. Effect of Termination. The provisions of Sections 5 through 9 hereof shall survive the termination of the Employee’s employment hereunder, regardless of the date, cause or manner of such termination, and such termination shall not impair or otherwise affect the Employee’s obligations to strictly observe the provisions of such Sections.

14. Miscellaneous.

(a) Assignment. The Employee may not assign this Agreement or any of his rights, benefits, obligations or duties hereunder to any other person, firm, corporation or other entity, said rights, duties

5

and obligations of the Employee being personal and nonassignable. This Agreement may be assigned by the Company without the Employee’s consent

(b) Non-Waiver. No waiver by either party of any breach by the other party of any provision hereof shall be deemed to be a waiver of an later or other breach thereof or as a waiver of any such or other provision of this Agreement.

(c) Law Applicable. This Agreement is governed by the laws of the State of South Carolina, without reference to principles of conflict of laws.

(d) Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Company, its successors and assigns. This Agreement shall be binding upon and inure to the benefit of the Employee, his heirs, executors and administrators.

(e) Entire Agreement. This Agreement, and any signed offer letter, constitute the entire agreement between the parties with respect to the subject matter hereof and supersede and cancel all prior or contemporaneous oral or written agreements and understandings between them with respect to the subject matter hereof, except for the signed and accepted offer letter between Company and Employee, if any. In the event any portion of this Agreement is inconsistent with the aforementioned offer letter, this Agreement shall apply. This Agreement may not be changed or modified orally but only by an instrument in writing signed by the parties hereto, which instrument states that it is an amendment to this Agreement.

In the event that any provision of this Agreement shall be held to be invalid or unenforceable, the remaining provisions thereof shall nevertheless continue to be valid and enforceable as though the invalid or unenforceable provision(s) had not been included therein. In the event that any provision of Sections 8 or 9 relating to the time period and/or the geographical area of restriction and/or related aspects is found by a court of competent jurisdiction to exceed the maximum restrictiveness such court deems reasonable and enforceable, then it is the express desire and intent of both parties that such provision not be rendered invalid thereby, but rather that the duration, geographic scope, or nature of the restriction be deemed reduced or modified to the extent necessary to render such provision reasonable, valid and enforceable. The time period and/or geographical area of restriction and/or related aspects deemed reasonable and enforceable by the court shall then become, and thereafter be, the maximum restriction in such regard, and the provision, as reformed, shall remain valid and enforceable

(g) Execution. This Agreement may be executed in duplicate counterparts, each of which shall be deemed an original hereof.

(h) Withholding. Notwithstanding any other provision of this Agreement, the Company may withhold from amounts payable under this Agreement all federal, state, local and foreign taxes that are required to be withheld by applicable laws or regulations.

MOREOVER, EMPLOYEE SPECIFICALLY UNDERSTANDS AND ACKNOWLEDGES THAT THIS AGREEMENT DOES NOT ALTER HIS AT-WILL EMPLOYMENT STATUS WITH THE COMPANY.
