                    ---------------

              As to this Note, the Executive waives all applicable exemption
rights, whether under any state constitution, homestead laws or otherwise, and
also waives valuation and appraisement, presentment, notice of dishonor, and
protest, notice of demand and nonpayment of this Note, and notice of
acceleration and expressly agrees that the maturity of this Note, or any payment
under this Note, may be extended from time to time without in any way affecting
the liability of the Executive.

              9.0   Preservation of Company Rights
                    ------------------------------

              No failure on the part of the Company to exercise any right or
remedy hereunder, whether before or after the happening of an Event of Default
shall constitute a waiver thereof, and no waiver of any past Event of Default
shall constitute waiver of any future default or of any other Event of Default.
No failure to accelerate the indebtedness evidenced hereby by reason of any
Event of Default hereunder, or acceptance of a past due payment, or indulgence
granted from time to time, shall be construed to be a waiver of the right to
insist upon prompt payment thereafter, or shall be deemed to be a novation of
this Note or as a reinstatement of the indebtedness evidenced hereby or as a
waiver of such right or acceleration or any other right, or be construed so as
to preclude the exercise of any right that the Company may have, whether by the
laws of the State of Mississippi, by agreement, or otherwise; the Executive
hereby expressly waives the benefit of any statute or rule of law or equity that
would produce a result contrary to or in conflict with the foregoing.

              10.0  Amendments
                    ----------

              This Note may not be amended orally, but only by an agreement in
writing signed by the party against whom such agreement is sought to be
enforced.

              11.0  Severability
                    ------------

              In case any provision or any part of any provision contained in
this Note shall for any reason be held to be invalid, illegal, or unenforceable
in any respect, such invalidity, illegality, or unenforceability shall not
affect any other provision or remaining part of the affected provision of this
Note, but this Note shall be construed as if such invalid, illegal, or
unenforceable provision or part thereof had never been contained herein.

              12.0  Arbitration
                    -----------

              Any allegation, claim, cause of action, demand or dispute
(collectively referred to as a "Dispute"), directly or indirectly related to
this Note shall be resolved through binding arbitration conducted in accordance
with the American Arbitration Association National Rules for the Resolution of
Employment Disputes, in effect on the date the demand for arbitration is
asserted. In the event that either Party demands arbitration, the Executive and
the Company agree that the proceeding shall be the exclusive, final and binding
forum for the ultimate resolution of any Dispute, subject to any rights of
appeal that either Party may have under the Federal Arbitration Act and/or under
applicable state law dealing with the review of arbitration decisions. The
Dispute shall be heard and determined by one arbitrator who is either a retired
judge or a licensed lawyer, experienced in arbitrating or adjudicating
employment-related Disputes.

              13.0  Governing Law
                    -------------
