                  Re:      Agreement and General Release

Dear Wendy:

         On August 31, 1999 I executed an Agreement and General Release between
Cotton States and Me. I was advised by Cotton States, in writing, to consult
with an attorney of my choosing prior to executing this Agreement and General
Release.

         More than seven (7) days have passed since I executed the Agreement
and General Release. I have at no time revoked my acceptance or execution of
that Agreement and General Release and reaffirm my acceptance of it. Therefore,
in accordance with the terms of our Agreement and General Release, I request
payment of the monies described in paragraph 2 of that Agreement.

                               Very truly yours,

                               /s/  Gary Meader

                  Commitment Percentage bears to the amount of such Letter of
