NOW THEREFORE, in consideration of the mutual covenants and conditions herein contained and other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, the parties hereby agree as set forth herein:

1. Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in the Voting Agreement.

3. Except as amended hereby, the Voting Agreement shall continue to be in full force and effect, and the execution and delivery of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of either party thereto. Neither this Amendment nor any term hereof may be amended other than by an instrument in writing signed by Buyer, Merger Sub and the Company Shareholders.

4. This Amendment may be executed in multiple counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute but one and the same agreement. Delivery of an executed counterpart of a signature page to this Amendment by facsimile or other electronic means shall be effective as delivery of a manually executed counterpart of this Amendment.

5. This Amendment, including its existence, validity, construction, and operating effect, and the rights of each of the parties hereto, shall be governed by and construed in accordance with the laws of the State of Georgia without giving effect to any conflicts or choice of laws provisions that would cause the application of the domestic substantive laws of any other jurisdiction.

6.
