              IN THE CHANCERY COURT OF THE FIRST JUDICIAL DISTRICT
                          OF HINDS COUNTY, MISSISSIPPI

IN THE MATTER OF THE ESTATE OF
ROBERT M. HEARIN, DECEASED                                   CAUSE NO. P-9294R-1

                     ORDER ACCEPTING REPORT OF CO-EXECUTORS
                     --------------------------------------

         This matter coming on  Report  of  Co-Executors  of  the  Estate  of
Robert  M. Hearin  in accord with order of this court dated September 22, 1995,
and the court finds as follows:

                                       1.

         Petitioners have established the Robert M. Hearin Support Foundation
naming Robert M. Hearin, Jr., Matthew L.  Holleman, III, Daisy S. Blackwell,
E.E. Laird, Jr., Laurie H. McRee, and Alan W. Perry as Trustees in the form
authorized in said order and have mailed a copy of said agreement to the
attorney general and to the organizations named therein in accordance with said
order.

                                       2.

         In accord with the previous order the Trustees of the Robert M. Hearin
Support Foundation have filed appropriate request with the Internal Revenue
Service for approval of the Foundation under Section 509(a)(3) of the Internal
Revenue Code and have filed with the court a copy of the determination letter
of Internal Revenue Service dated December 4, 1995 approving said application.

                                       3.

         Petitioners now are prepared to distribute the assets remaining in the
estate to  the  Robert M. Hearin Support Foundation in accordance with said
order.
<PAGE>   10
                                       4.

         All necessary parties were before this court for purposes of closing
the estate and discharging Executor as determined by the court in its order of
April 6, 1994 wherein the beneficiaries entered their appearance therein for
all purposes. The court modified said order by delaying distribution of the
remaining assets of the estate and by order of September 22, 1995 construed the
Will and Codicils of Robert M. Hearin pursuant to the Doctrine of Equitable
Approximation to provide that the Robert M. Hearin Support Foundation shall be
the recipient of all assets now in the estate which would otherwise be
distributed to the existing Robert M. Hearin Foundation, not effecting bequests
to any other beneficiary. The court finds that all necessary parties are before
the court and the estate is now ready for closing and final distribution of
assets.

                                       5.

         Petitioners are advised that by reason of the fact that the decedent
owned or controlled sufficient voting stock of Perry County Bank, that the
Robert M. Hearin Support Foundation could be considered a Bank Holding Company
pursuant to the provisions of Federal Banking Regulations. In order to avoid
such a classification, Petitioners are seeking to dispose the stock of Perry
County Bank and anticipate that such a disposition will be accomplished within
the next several months. The court finds that Petitioners should be authorized
to retain the shares of stock of Perry County Bank in the estate for an
additional six month period, within which to negotiate a disposition thereof.

         IT IS THEREFORE ORDERED, ADJUDGED AND DECREED that the Report of
Co-Executors is received; that Petitioners are authorized to distribute the
remaining assets of the

                                       2
<PAGE>   11
estate to the Robert M. Hearin Support Foundation with the exception of the
shares of Perry County Bank, which said shares shall be retained in the estate
for a period of six months within which the Co-Executors shall seek the
disposition thereof; that upon filing of proper receipts for said assets,
Petitioners are discharged of their duties as Co-Executors in accordance with
the order closing the estate dated April 6, 1994 as modified by Order
Establishing Support Foundation dated September 22, 1995.

         SO ORDERED this the 29th  day of December  1995.
                             ----         --------    --

                 Issuer by any person;

         (h)     there are no plans to cause any class of securities of the

             126,717(l) shares (5.82%) with sole voting and dispositive power
                   0    shares (0%) with shared voting and dispositive power.

         Transactions within the past 60 days prior to September 29, 1984 by
         reporting person:

                 43,493 shares were received September 29, 1984 in a merger
                 transaction in exchange for shares of Merchants and Planters
                 Bank of Hazlehurst, Mississippi and State Guaranty Bank of
                 Magee, Mississippi.  In the merger, former shareholders of
                 Merchants and Planters received 12.361 shares of Issuer's
                 common stock in exchange for each share of Merchants and
                 Planters common stock they owned. State Guaranty shareholders
                 received 7.845 shares of Issuer's common stock in exchange for
                 State Guaranty's common stock they owned.

                 Hearin is a Director and, indirectly, a significant
                 shareholder of Lamar Life Corporation, he does not claim
                 beneficial ownership of Issuer's shares owned by that Company.

         (a)     no additional acquisition of Issuer's securities is presently
                 contemplated nor is any disposition of Issuer's securities
                 anticipated; however, additional shares of Issuer's securities
                 may be acquired in the future and/or a disposition of Issuer's
                 shares owned by the reporting person may occur at some future
                 date;

         (b)     no extraordinary corporate transaction, merger,
                 reorganization, or liquidation involving the Issuer or any of
                 its subsidiaries is presently contemplated;

         (c)     no sale or transfer of a material amount of the assets of the
                 Issuer or its subsidiaries is presently contemplated;

         (d)     there are no plans to propose a change in the present Board of

                 action which may impede the acquisition of control of the
                 Issuer by any person;

         (h)     there are no plans to cause any class of securities of the
                 Issuer to be delisted from a national securities exchange or
                 to cease to be authorized to be quoted in an inter-dealer
                 quotation system of a registered national securities
                 association;

         (i)     there are no plans to make a class of equity securities of the

                          13D on Capitol Street Corporation filed herewith).

                 (1)      In previous 13D reportings, reporting person did not
                          include the 608,111 shares (6.2%) of Issuer's common

                          disclaimed beneficial ownership thereof. Reporting
