Company  terminates  his  employment  for Cause or the Executive  terminates his
employment  without Good Reason for a period of twelve (12) months thereafter he
will not (except as a representative of the






Company or with the prior written  consent of the Board) engage,  participate or
make any financial investment,  as an employee,  director,  officer,  associate,
consultant,  agent, independent contractor,  lender or investor, in the business
of any  person,  firm,  partnership,  corporation  or other  enterprise  that is
engaged in direct  competition  with the business of the Company in the State of
Mississippi.  Nothing in this  paragraph B shall be  construed  to preclude  the
Executive  from  making  any  investments  in the  securities  of  any  business
enterprise whether or not engaged in competition with the Company, to the extent
that such securities are actively traded on a national securities exchange or in
the  over-the-counter  market in the United States or on any foreign  securities
exchange and represent less than  one-percent (1%) of any class of securities of
such business enterprise.
     4.  Non-Assignment.  This Agreement and all of the  Executive's  rights and

payments under this Agreement shall inure to the benefit of his widow,  personal
representative,  designees or other legal  representatives,  as the case may be.
Any person,  firm or  corporation  succeeding  to the business of the Company by
merger,  purchase,  consolidation  or  otherwise  shall  assume by  contract  or
operation of law the obligations of the Company  hereunder,  provided,  however,
that the Company  shall,  notwithstanding  such  assumption,  remain  liable and
responsible for the fulfillment of its obligations under this Agreement.
     5. Severability.  Whenever possible,  each provision of this Agreement will
be interpreted in such manner as to be effective and valid under applicable law,
but if any  provision  of  this  Agreement  is held to be  invalid,  illegal  or
unenforceable   in  any  respect  under  any  applicable  law  or  rule  in  any
jurisdiction such invalidity,  legality or unenforceability  will not affect any
other provision or any other jurisdiction,  but this Agreement will be reformed,
construed  and  enforced in such  jurisdiction  as if such  invalid,  illegal or
unenforceable provision had never been contained herein.

hereunder  shall be in writing and shall be delivered  personally,  telegraphed,
