     1. Confidential Information. Except as may be required by the lawful order
        ------------------------

     3.   Noncompetition. While the Executive is employed by the Company and its
          --------------
affiliates, and for a period of two years after the date the Executive
terminates employment with the Company and its affiliates, the Executive

     4.   Rights and Payments Upon Termination. The Executive's right to
          ------------------------------------
benefits and payments, if any, for periods after the date on which his

shall be determined in accordance with this Section 4:

     (A)  Termination by the Company for Reasons Other Than Cause; Termination
          --------------------------------------------------------------------
          by the Executive for Good Reason. If the Executive's termination by
          --------------------------------
          the Company occurs for any reason other than Cause or is a result of
          the Executive's termination of employment for Good Reason (and is not
          on account of the Executive's death, disability, or voluntary
          resignation, the mutual agreement of the parties or any other reason),
          then the Executive shall receive from the Company for the period
          commencing on his Termination Date and ending on the earliest of (i)
          the twenty-fourth month after the Executive's Termination Date; (ii)
          the date on which the Executive violates the provisions of Sections 1,
          2 or 3 of this Agreement; or (iii) the date of the Executive's death,
          the Salary, bonus and benefits in effect as of his Termination Date.
          The biweekly salary amounts will continue as described above. Benefits
          that will continue will include medical, dental, basic life insurance,
          any optional life insurance and any optional accidental death and
          dismemberment insurance. Bonus shall mean two payments of the average
          annual amount of the award paid to the Executive pursuant to the

<PAGE>

          Base salary payments to the Executive during the aforementioned
          twenty-four month period shall not preclude the Executive's
          eligibility for payments under the Company's severance plan.

          Twenty-four months of additional age and service credit will be
          provided to the Executive's RT Pension and the RT Supplemental Plan
          using the methodology described in the Executive's Change in Control
          Agreement except that any lump sum payment will be made twenty-four
          months after the Executive's Termination Date and only if the
          Executive has not violated the Confidentiality, Nonsolicitation and
          Noncompetition provisions of this Agreement.

     (B)  Termination By Company for Cause. If the Executive's termination is a
          --------------------------------
          result of the Company's termination of the Executive's employment on
          account of Cause, then, except as agreed in writing between the
          Executive and the Company, the Executive shall have no right to future
          payments or benefits under this Agreement (and the Company shall have
          no obligation to make any such future payments or provide any such
          future benefits) for periods after the Executive's Termination Date.

     (C)  Termination for Death or Disability. If the Executive's termination is
          -----------------------------------
          caused by the Executive's death or permanent disability, then the
          Executive (or in the event of his death, his estate) shall be entitled
          to continuing payments of his Salary for the period commencing on his
          Termination Date and ending on the earlier of (i) the last day of the
          calendar month in which his Termination Date occurs or (ii) the date
          on which the Executive violates the provisions of Sections 4, 5 or 6
          of this Agreement.

     (D)  Termination for Voluntary Resignation, Mutual Agreement or Other
          ----------------------------------------------------------------
          Reasons. If the Executive's termination occurs on account of his
          -------
          voluntary resignation, mutual agreement of the parties, or any reason
          other than those specified in Paragraphs (A) or (B) above then, except
          as agreed in writing between the Executive and the Company, the
          Executive shall have no right to future payments or benefits under
          this Agreement (and the Company shall have no obligation to make any
          such future payments or provide any such future benefits) for periods

                    Executive Vice President; or

               (c)  conduct by the Executive that involves theft, fraud or
                    dishonesty; or

               office or responsibilities or a reduction in his rate of Salary,

the subject matter hereof and shall supersede any prior agreements to the
contrary.

accordance with the laws of the State of Georgia.
