                                  MISCELLANEOUS

         6.1      Incapacity. If the Plan Administrator determines that any
person entitled to benefits hereunder is unable to care for his affairs because
of illness or accident, any payment due (unless a duly qualified guardian or
other legal representative has been appointed) may be paid for the benefit of
such person to his or her spouse, parent, brother, sister or other party deemed
by the Plan Administrator to have incurred expenses for such person. Any such
payment, to the extent paid, shall discharge the Company's obligation therefore
and the Company shall not be responsible for the use of such payment after
payment is made.

         6.3      Required Information. Any person eligible to receive benefits
hereunder shall furnish to the Plan Administrator any information or proof
requested by the Plan


                                       5
<PAGE>   6

Administrator and reasonably required for the proper administration of the Plan.
Failure on the part of any person to comply with any such request within a
reasonable period of time shall be sufficient grounds for delay in the payment
of any benefits due under the Plan until such information or proof is received
by the Plan Administrator. If any person claiming benefits under the Plan makes
a false statement that is material to such person's claim for benefits, the
Company may offset against future payments any amount paid to such person to
which such person was not entitled under the provisions of the Plan.

         6.4      Policy Claims.  Any claim for benefits under a Policy shall be
subject to and governed by the terms of the Policy.

         6.5      No Right To Employment. Nothing in this Plan or any Agreement
shall be deemed to constitute a contract of employment or to give any Employee
the right to be retained in the service of the Company or a Subsidiary or to
interfere with the right of the Company or a Subsidiary to discharge any
Employee at any time without regard to the effect that such discharge may have
upon the Employee or Participant under the Plan.

         6.6      Withholding Taxes. The Plan Administrator may make any
appropriate arrangements to deduct from all amounts paid or payable under the
Plan or from other amounts paid or payable to the Employee any taxes required to
be withheld by any government or government agency. The Employee shall pay all
taxes on amounts paid under the Plan to the extent that no taxes are withheld,
irrespective of whether withholding is required.

         6.7      Gender and Number. In order to shorten and to improve the
understandability of the Plan document by eliminating usage of such phrases as
"his or her" and "Subsidiary or Subsidiaries," any masculine terminology herein
shall also include the feminine and neuter, and the definition of any term used
herein in the singular shall also include the plural, except when otherwise
indicated by the context.

         6.8      Headings.  Any headings used in this document are for
convenience of reference only and are to be ignored in the construction of any
provision hereof.

affect the remaining parts of the Plan,


                                       6

and the Plan shall be construed and enforced as if such illegal or invalid
provision had never been inserted herein.

         6.10     Governing Law.  The Plan shall be construed, administered and
regulated in accordance with the laws of the State of Alabama, except to the
extent that such laws are preempted by Federal law.
