conditions set forth in a written instrument as determined by the Committee from time to time. The Options will include (but not by way of limitation) the following:

requirements of any stock exchange or nation market system on which the Shares may then be listed. If the issuance or transfer of Shares to be issued or issued pursuant to any Option granted under the Plan may in the opinion of counsel to the
Company conflict or be inconsistent with or not be permitted under any applicable law or regulation of any governmental agency having jurisdiction, including, without limitation, regulations promulgated pursuant to federal and state securities laws,
the Company reserves the right to delay the issuance of the Shares upon the exercise of an Option and such delay shall be without liability to or other obligation of the Company. The Company shall have no obligation hereunder to file registration
statements or other reports or notices or obtain any license or permit or exemption under any federal or state law with respect to the grant of an Option or the issuance of Shares upon the exercise of an Option or the transfer of such Shares at any
time thereafter. The Board of Directors or Committee may require that the holder of an Option, as a condition to each exercise of the Option in whole or in part, to represent to the Company in writing that the Shares to be acquired upon the exercise
of the Option are to be acquired by the holder of the Option for investment purposes only, for such persons own account, and not with a view to distribution and make such other representations as counsel to the Company may reasonably request
to assure the availability of an exemption from or compliance with the registration, notice, reporting or permitting requirements of applicable federal or state securities laws. The Option may also set forth such other terms and

| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|F. | Disposition of Shares - In the event the disposition of Shares acquired upon the exercise of any Option is not covered by a then current registration statement under the

with the Company, Subsidiary or the Parent, as the case may be, to secure that such a payment is made.
|-- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|H. | National Insurance Contributions Joint Election - Without prejudice to the generality of clause VI. E. above (Conditions to Exercise of Options), the Optionees who are
subject to the laws of the United Kingdom may not exercise, release or assign an Option granted under the Plan in any circumstances unless and until the Board of Directors is satisfied that the Optionee has entered into a binding election in the
form prescribed by the Company pursuant to which the Optionee assumes liability for the whole of the employers National Insurance contributions in respect of share option gains arising from the Option.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

be purchased and accompanied by payment therefor and other consideration in accordance with the Option. The holder of an Option shall not be deemed to be a
holder of any Shares subject to any Option and shall not be entitled to the rights of a holder of any Shares, including the right to vote the Shares and to receive dividends, unless and until such Shares have been issued.



VIII. TERMINATION AND AMENDMENT.



The Board of Directors may at any time terminate the Plan, or make such
amendments thereto or modifications thereof as it shall deem advisable, including amendments deemed necessary or desirable to conform any ISO to any change in the Code or regulations thereto; provided, however, that the Board of Directors may not,
without further approval by the shareholders of the Company, increase the maximum number of Shares for which Options may be granted under the Plan or change the designation of the class of employees and other persons eligible to receive Options. No
termination, modification or amendment of the Plan shall, without the consent of the Optionee to whom an Option shall theretofore have been granted, adversely affect the rights of such Optionee under such Option without the written consent of such
Optionee.



IX. MISCELLANEOUS.



|A. | Applicable Law. The Plan shall be governed and construed in accordance with the laws of the State of Georgia.
|-- | -------------------------------------------------------------------------------------------------------------



|B. | Employee/Employer Rights. The granting of Options hereunder shall be entirely discretionary and nothing in the Plan shall be deemed to give any person any right of continued
employment or give any person any right to receive Options or additional Options hereunder or interfere in any way with the right of the Company, its Parent or Subsidiary to terminate the Optionees employment for any reason or the right of the
Optionee to terminate his/her employment for any reason. Without prejudice to the generality of the foregoing, participation in this Plan is a matter entirely separate from any pension right or entitlement an Optionee may have and from their terms
and conditions of employment and in particular (but without limiting the generality of the foregoing) any individual who leaves the employment of the Company or its Subsidiaries, or the Parent or who otherwise ceases to be an employee shall not be
entitled to any compensation for any loss of any right or benefit or prospective right or benefit under the Plan which the Optionee might otherwise have enjoyed whether such compensation is claimed by way of damages for wrongful dismissal or other
breach of contract or by way of compensation for loss of office, employment or otherwise howsoever.

|C. | ISO Grants. The Plan is intended to provide in part for the grant of ISOs pursuant to Section 422 of the Code, including amendments thereto hereafter adopted, and
the provisions of the Plan as they relate to ISOs and the ISOs granted shall be construed to effectuate such purpose. If for any reason it is subsequently determined that an Option intended to qualify as an ISO does not so qualify, the
Company, Parent and Subsidiary shall have no liability to the Optionee and such Options shall be deemed to be Non-Qualified Stock Options.
