Summary of compensation arrangements with directors.



 Exhibit 10.16 
  
 Director Compensation 
  
 Directors who are not also employees of the Company (“Nonemployee Directors”) receive a retainer of $25,000 per year payable in a lump sum
following each annual meeting of shareholders. No meeting fees are payable to the Nonemployee Directors. Nonemployee Directors are reimbursed upon request for reasonable expenses incurred in attending Board of Director or committee meetings.

  
 At each regular annual meeting of shareholders, the Company
grants to each Nonemployee Director a non-qualified stock option covering 5,000 shares of common stock (except that such stock option covers 25,000 shares of common stock for Nonemployee Directors upon their initial election as a director of the
Company). In recognition of added responsibilities for chairing the Board’s Audit, Compensation and Nominating Committees, each such chair has been granted a non-qualified stock option covering 10,000 shares of common stock at each regular
annual meeting of shareholders. Each of these stock options has an exercise price equal to the fair market value of the Company’s common stock on the date of grant. These option grants may be exercised only by the optionee until the earlier of
five years after the date of grant or one year after ceasing to be a director of the Company. 
  
 Non-employee directors may elect to enroll themselves and their eligible dependents in the Company’s group health insurance plan provided that the enrolled director pays the premium cost incurred by the Company
to maintain such insurance benefits. Mr. McGrevin is the only non-employee director who has elected to enroll in such benefit. 
  
 The Company’s Articles of Incorporation adopt the provisions of the Georgia Business Corporation Code (the “Corporation Code”) providing
that no member of the Company’s Board of Directors shall be personally liable to the Company or its shareholders for monetary damages for any breach of his duty of care or any other duty he may have as a director, except liability for any
appropriation, in violation of the director’s duties, of any business opportunity of the Company, for any acts or omissions that involve intentional misconduct or a knowing violation of law, for liability under the Corporation Code for unlawful
distributions to shareholders, and for any transaction from which the director receives an improper personal benefit. 
  
 The Company’s Bylaws provide that each officer and director shall be indemnified for all losses and expenses (including attorneys’ fees and
costs of investigation) arising from any action or other legal proceeding, whether civil, criminal, administrative or investigative, including any action by and in the right of the Company, because he is or was a director, officer, employee or agent
of the Company or, at the Company’s request, of any other organization. In the case of action by or in the right of the Company, such indemnification is subject to the same exceptions, described in the preceding paragraph, that apply to the
limitation of a director’s monetary liability to the Company. The Bylaws also provide for the advancement of expenses with respect to any such action. The Bylaws permit the Company to enter into agreements providing to each officer or director
indemnification rights substantially similar to those set forth in the Bylaws, and such agreements have been entered into between the Company and each of the members of its Board of Directors and certain of its executive officers.
