                          [THE FIRST CORPORATION LOGO]



                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

   
         The First Corporation has entered into a merger agreement with
BancorpSouth, Inc. which provides that, subject to shareholder and regulatory
approval and other conditions, The First Corporation will merge into
BancorpSouth, Inc. In connection with that transaction, The First National Bank
of Opelika, a subsidiary of The First Corporation, will merge into BancorpSouth
Bank, a subsidiary of BancorpSouth, Inc. The combined company will have banking
operations in Mississippi, Tennessee and Alabama, and, based upon the companies'
September 30, 1998 balance sheets, total assets of about $4.51 billion, deposits
of about $3.81 billion and shareholders' equity of about $405.1 million.
    

   
         If the merger is completed, shareholders of The First Corporation will
receive shares of BancorpSouth, Inc. common stock in exchange for their shares
of common stock of The First Corporation. However, rather than receiving any
fractional shares of BancorpSouth common stock, you will receive cash in lieu of
any fraction of a share of BancorpSouth common stock to which you otherwise
would be entitled. BancorpSouth, Inc. common stock is listed on the New York
Stock Exchange under the symbol "BXS." On November 19, 1998, the closing price
per share of BancorpSouth, Inc. common stock reported on the New York Stock
Exchange was $20.75.
    

         The merger cannot be completed without the approval of The First
Corporation's shareholders. The First Corporation has scheduled a special
meeting for its shareholders to vote on the merger agreement. In order for the
merger to be approved, at least two-thirds of the outstanding shares of common
stock of The First Corporation must be voted in favor of the merger agreement.
The date, time and place of the special meeting is as follows:

                              ______________, 1998
                            ______ __.m. (local time)
                       The First National Bank of Opelika
                            414 South Seventh Street
                             Opelika, Alabama 36801.

         YOUR VOTE IS VERY IMPORTANT. Whether or not you plan to attend your
special shareholders meeting, please take the time to vote by completing and
mailing the enclosed proxy card to us. If you sign, date and mail your proxy
card without indicating how you want to vote, your proxy will be counted as a
vote in favor of the merger agreement. If you don't return your card, the effect
will be a vote against the merger agreement.

         The attached Prospectus Supplement/Proxy Statement provides you with
detailed information about the proposed merger and the companies involved. We
encourage you to read this entire document carefully. You can also obtain
information about BancorpSouth, Inc. from documents it has filed with the
Securities and Exchange Commission.

         The Board of Directors of The First Corporation unanimously recommends
that shareholders vote "FOR" approval of the merger agreement.

                                          Very truly yours,



                                          William C. Kent

                              QUESTIONS AND ANSWERS
                                ABOUT THE MERGER

Q:       WHAT DO I NEED TO DO NOW?

A:       Whether or not you plan to attend the special meeting of The First
         Corporation shareholders, please indicate on the enclosed proxy card
         how you want to vote, and sign and mail the proxy card in the enclosed
         return envelope as soon as possible so that your shares may be
         represented at the special shareholders meeting. If you sign and send
         in your proxy but don't indicate how you want to vote, your proxy will
         be counted as a vote in favor of the merger agreement between The First
         Corporation and BancorpSouth. If you don't vote on the merger agreement
         or if you abstain, the effect will be a vote against the merger
         agreement.

         You are invited to the special shareholders meeting to vote your shares
         in person. If you do sign your proxy card, you can take back your proxy
         at any time until the special shareholders meeting and either change
         your vote or attend the special shareholders meeting and vote in
         person.

         Regardless of whether you plan to attend the special meeting in person,
         we encourage you to complete and return your signed proxy using the
         enclosed reply envelope. This will help to ensure that a quorum is
         present at the special meeting and will help reduce the costs
         associated with the solicitation of proxies.

         THE BOARD OF DIRECTORS OF THE FIRST CORPORATION UNANIMOUSLY RECOMMENDS
         VOTING "FOR" APPROVAL OF THE MERGER AGREEMENT.

Q:       IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER 
         VOTE MY SHARES FOR ME?

A:       Only if you provide instructions to your broker on how to vote by
         following the directions your broker provides. Without instructions
         from you to your broker, your shares will not be voted and this will
         effectively be a vote against the merger agreement.

Q:       SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:       No. After the merger is completed, you will be sent written 
         instructions on how to exchange your shares of common stock of The 
         First Corporation for shares of BancorpSouth common stock.

Q.       WHOM DO I CONTACT IF I HAVE QUESTIONS ABOUT THE MERGER?

A:       If you have more questions about the merger, you should contact:

billion and shareholders' equity of about $389.1 million.

         On October 30, 1998, Alabama Bancorp., Inc., a bank holding company
based in Birmingham, Alabama, merged into BancorpSouth. In connection with that
merger, Highland Bank and First Community Bank of The South (which were
subsidiaries of Alabama Bancorp., Inc.) merged into BancorpSouth Bank. Highland
Bank operated seven banking locations in the metropolitan Birmingham, Alabama
area and First Community Bank operated four banking locations in the Fort
Deposit, Alabama area. As of September 30, 1998, Alabama Bancorp., Inc. and its
subsidiaries had total assets of about $275.4 million and total deposits of
about $243.3 million.

         On May 2, 1998, BancorpSouth entered into a merger agreement with
Merchants Capital Corporation, a bank holding company based in Vicksburg,
Mississippi. The merger agreement provides for the merger of Merchants Capital
Corporation into BancorpSouth, and the merger of Merchants Bank (a wholly-owned
subsidiary of Merchants Capital Corporation) into BancorpSouth Bank. Merchants
Bank operates six banking locations in the Vicksburg, Mississippi area and a
loan production office in Jackson, Mississippi. As of September 30, 1998,
Merchants Capital Corporation and its subsidiaries had total assets of about
$211.4 million and total deposits of about $173.5 million. This merger, which is
subject to regulatory approval and other conditions described in the merger
agreement, is expected to be completed during December 1998. The parties have
structured the merger as a tax-free exchange of common stock and intend to
account for the merger as a pooling of interests.

         On November 4, 1998, BancorpSouth entered into a merger agreement with
HomeBanc Corporation, a bank holding company based in Guntersville, Alabama. The
merger agreement provides for the merger of HomeBanc Corporation into
BancorpSouth, and the merger of The Home Bank (a wholly-owned subsidiary of
HomeBanc Corporation) into BancorpSouth Bank. The Home Bank operates one banking
location in Guntersville, Alabama, two banking locations in Albertville,
Alabama, one banking location in Arab, Alabama and one banking location in Boaz,
Alabama. As of September 30, 1998, HomeBanc Corporation and its subsidiary had
total assets of about $____ million and total deposits of about $____ million.
This merger, which is subject to regulatory approval and other conditions
described in the merger agreement, is expected to be completed during February
1999. The parties have structured the merger as a tax-free exchange of common
stock and intend to account for the merger as a pooling of interests.

THE FIRST CORPORATION
414 South Seventh Street
Opelika Alabama 36801
(334) 749-2041

   
         The First Corporation is incorporated in the State of Alabama and is a
registered bank holding company under the Bank Holding Company Act of 1956, as
amended. It is based in Opelika, Alabama and is the sole shareholder of The
First National Bank of Opelika, which is a national banking association with two
banking locations in Opelika, Alabama and one banking location in Auburn,
Alabama. The First Corporation's principal asset is the stock of its subsidiary.
As of September 30, 1998, The First Corporation and its subsidiary had total
assets of about $143.4 million, deposits of about $121.5 million and
shareholders' equity of about $15.95 million.
    

THE MERGER (PAGE 30)

         BancorpSouth and The First Corporation entered into a merger agreement
whereby The First Corporation will merge into BancorpSouth, subject to
shareholder and regulatory approval and other conditions. The merger agreement
is attached to this Prospectus Supplement/Proxy Statement as Annex A. You should
read it carefully.

         If this merger is completed, the businesses and operations of
BancorpSouth and The First Corporation will be combined into a single, larger
company and The First National Bank of Opelika will combine with BancorpSouth
Bank into a single, larger bank. The parties hope to complete the merger by the
end of December 1998, after obtaining approvals from the shareholders of The
First Corporation, the Federal Deposit Insurance Corporation and Mississippi and
Alabama banking authorities.

         If the merger is completed, The First Corporation shareholders will
receive a maximum of 10.4235 shares and a minimum of 7.7043 shares of
BancorpSouth common stock for each share of The First Corporation common stock
they own. BancorpSouth will not issue any fractional shares of BancorpSouth
common stock. Instead, you will receive cash equal to the product of (1) the
average closing price of BancorpSouth common stock as reported on the New York
Stock Exchange during the ten consecutive trading days ending on the third
business day before the date on which the merger is completed, times (2) the
fraction of a share of BancorpSouth common stock to which you otherwise would be
entitled.

         The number of shares of BancorpSouth common stock to be exchanged for
each share of common stock of The First Corporation (which is referred to as the
"exchange ratio") will be determined by dividing $174.8178 by the average
closing price of BancorpSouth common stock as reported on the New York Stock
Exchange during the ten consecutive trading days ending on the third business
day before the date on which the merger is completed. For example, if the
average closing price of BancorpSouth common stock is equal to $22.50, the
exchange ratio for The First Corporation common stock would be 7.7697 (or
$174.8178 / $22.50), and 7.7697 shares of BancorpSouth common stock would be
issued for each share of The First Corporation common stock. If the average
closing price is equal to $17.00, the exchange ratio for each share of The First
Corporation common stock would be 10.2834 (or $174.8178 / $17.00), and 10.2834
shares of BancorpSouth common stock would be issued for each share of The First
Corporation common stock.

         The range of the exchange ratio is designed to reduce the impact of
fluctuations in the market price of BancorpSouth common stock prior to
completion of the merger. The following table shows the implied market value of
the consideration that shareholders of The First Corporation will receive in the
merger for each share of The First Corporation common stock (assuming that the
exchange ratio formula results in a number that is equal to or between the
minimum and maximum exchange ratio amounts). The market price of BancorpSouth
common stock will vary prior to and after the merger, and could decrease.

</TABLE>
- --------------------
(1)      Based upon the average closing price per share of BancorpSouth common 
         stock during the ten consecutive trading days ending on the third 
         business day prior to the date on which the merger is completed.
(2)      Assumes that the average closing price per share of BancorpSouth common
         stock for purposes of computing the exchange ratio is not less than
         about $16.7715 or more than about $22.6909, which would result in the
         minimum and maximum exchange ratios.

         The exchange ratio is limited by a minimum and maximum amount, even if
the exchange ratio formula results in a number outside of that range. That is,
the exchange ratio cannot be more than 10.4235 or less than 7.7043. For example,
if the average closing price of BancorpSouth common stock was equal to $16.00,
then the exchange ratio would be the maximum amount of 10.4235, even though the
exchange ratio formula would result in a calculated amount of about 10.9261 (or
$174.8178 / $16.00).

         However, the merger agreement could be terminated if the calculated
amount of the exchange ratio is greater than 11.8132 or less than 7.0879.
BancorpSouth can elect to terminate the merger agreement if the calculated
amount of the exchange ratio is less than 7.0879 (which would occur if the
average closing price of BancorpSouth common stock used to compute the exchange
ratio was more than about $24.6643) unless The First Corporation agreed to lower
the minimum amount of the exchange ratio to an amount that is not less than the
calculated amount of the exchange ratio. Likewise, The First Corporation can
terminate the merger agreement if the calculated amount of the exchange ratio is
greater than 11.8132 (which would occur if the average closing price of
BancorpSouth common stock used to compute the exchange ratio was less than about
$14.7985) unless BancorpSouth agreed to increase the maximum amount of the
exchange ratio amount to an amount that is not more than the calculated amount
of the exchange ratio. There can be no assurance that either party would agree
to such an increase or decrease, or that either party would exercise its rights
to terminate the merger agreement in such event. The parties could elect to
proceed with the merger without adjusting the minimum or maximum amount of the
exchange ratio.

         The exchange ratio will be fixed on the third business day before the
date on which the merger is completed, based on the average closing price as
reported on the New York Stock Exchange during the ten trading day period ending
on that date. Therefore, until that date the actual amount of the exchange ratio
can't be determined, and we are not able to predict whether or not the computed
amount of the exchange ratio will be within the range of the minimum and maximum
exchange ratios. Until that time, fluctuations in the market price of
BancorpSouth common stock will cause the exchange ratio to increase or decrease,
depending upon whether the market price decreases or increases. After the
exchange ratio becomes fixed on the third business day prior to the merger, the
market value of the BancorpSouth common stock received in the merger may
increase or decrease.

         A common stock purchase right attaches to, and trades with, each share
of BancorpSouth common stock, including the shares of BancorpSouth common stock
that shareholders of The First Corporation will receive in the merger. Upon the
occurrence of certain events (including the acquisition of, or tender offer for,
20% or more of the outstanding shares of BancorpSouth common stock by any person
or entity), each of these common stock purchase rights (other than those held by
the person acquiring the shares or making the tender offer) will entitle the
holder of the right to purchase one share of BancorpSouth common stock for a
price per share equal to 50% of the then market price. These rights, which are
issued under BancorpSouth's shareholder rights plan (which 



                                       7

<PAGE>   11



is commonly referred to as a "poison pill"), may make it more difficult for any
person or entity to acquire control of BancorpSouth without the approval of
BancorpSouth's Board of Directors.

SPECIAL SHAREHOLDERS MEETING (PAGE 23)

         A special meeting of the shareholders of The First Corporation will be
held on ______, 1998 at the following time and place. At the special meeting,

BACKGROUND OF THE MERGER (PAGE 32)

         In June 1998, management of The First Corporation met separately with
representatives of two financial institutions that had expressed unsolicited
interest in pursuing a possible business combination with The First Corporation.
On June 18, 1998, the Board of Directors of The First Corporation engaged Alex
Sheshunoff & Co. Investment Banking, an independent investment advisory firm, to
assist the Board of Directors of The First Corporation in establishing a
reasonable value of the company and assisting in soliciting additional
expressions of interest regarding a potential business combination with The
First Corporation.

         Alex Sheshunoff & Co. Investment Banking promptly contacted six
additional financial institutions to solicit expressions of interest in
acquiring The First Corporation. BancorpSouth was contacted on June 30, 1998 by
Alex Sheshunoff & Co. Investment Banking to determine BancorpSouth's interest in
acquiring The First Corporation. Of these six additional financial institutions,
three, including BancorpSouth, expressed an interest in a business combination
with The First Corporation. On July 6, 1998, BancorpSouth presented an informal
presentation, which consisted primarily of an introduction to BancorpSouth, to
management of The First Corporation.

         After reviewing the expressions of interest from the initial two, and
additional three, financial institutions, the Board of Directors of The First
Corporation determined that offers from three of the five institutions were not
financially attractive enough to warrant further consideration. The remaining
two financial institutions, one of which was BancorpSouth, were allowed to
conduct a due diligence review of The First Corporation. On July 14, 1998,
BancorpSouth proposed to Alex Sheshunoff & Co. Investment Banking an acquisition
value of about 2.72 times the net book value of The First Corporation, or an
aggregate value of about $40.8 million. Upon completion of its due diligence
review, BancorpSouth increased its offer to an aggregate value of about $41.4
million.

         After considering each financial institution's final offers, the Board
of Directors of The First Corporation determined that BancorpSouth's offer was
the most attractive to The First Corporation and its shareholders. Between July
29, 1998 and August 11, 1998, representatives of BancorpSouth and The First
Corporation negotiated the merger agreement and the stock option agreement. On
August 12, 1998, the Board of Directors of The First Corporation approved the
merger and the merger agreement and stock option agreement. BancorpSouth and The
First Corporation each executed the merger agreement and the stock option
agreement later in the day on August 12, 1998. The Board of Directors of
BancorpSouth approved the merger and the merger agreement on August 26, 1998.

REASONS FOR THE MERGER (PAGE 34)

         The merger will combine the strengths of BancorpSouth and The First
Corporation, and that of their subsidiary banks. The combined company resulting
from the merger should be able to achieve superior financial performance
compared to each company operating independently. One reason for this is that
the combined company should be able to reduce costs substantially by eliminating
overlap in the companies' operations and by applying BancorpSouth's investments
in technology to The First Corporation's operations. Another reason is that the
combined company should have opportunities to increase revenue by bringing a
larger universe of customers in contact with a broader range of products and
services. The competitiveness of the financial services industry is increasing
continually, and the greater strength realized through combining the companies
should enable them to provide superior products and services to their customers
and substantial benefits to their shareholders.

FEDERAL INCOME TAX CONSEQUENCES (PAGE 40)

         The parties have structured the merger with the intent that The First
Corporation, its shareholders, BancorpSouth and its shareholders will not
recognize any gain or loss for U.S. federal income tax purposes in the merger,
except in connection with cash received instead of fractional 



                                       9


<PAGE>   13



shares by shareholders of The First Corporation, or with respect to shareholders
of The First Corporation who dissent from the merger under Alabama law. The
merger is conditioned on receipt of legal opinions that this will be the case,
but these opinions won't bind the Internal Revenue Service, which could take a
different view. Determining the actual tax consequences of the merger to you can
be complicated. They will depend on your specific situation and many variables
not within the companies' control. You should consult your own tax advisor for a
full understanding of the merger's tax consequences.

ACCOUNTING TREATMENT (PAGE 40)

         The parties expect that the merger of The First Corporation into
BancorpSouth will qualify as a pooling of interests, which means that, for
accounting and financial reporting purposes, BancorpSouth will treat the
combined companies as if they had always been one company.

FAIRNESS OPINION (PAGE 36)

         Alex Sheshunoff & Co. Investment Banking rendered an opinion to the
Board of Directors of The First Corporation that, as of the date of the opinion,
the exchange ratio was fair from a financial point of view to the shareholders
of The First Corporation. This opinion is attached as Annex C to this document.
You should read it carefully.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (PAGE 42)

         Directors and executive officers of The First Corporation will be
issued shares of BancorpSouth common stock in the merger on the same basis as
other shareholders of The First Corporation. The following chart shows the
number of shares of BancorpSouth common stock that may be issued to directors
and executive officers of The First Corporation in the merger:

                Shares of common stock of The First Corporation
                beneficially owned by its executive officers and
                directors on ____________, 1998 (1)............      55,885.41

                Maximum number of shares of BancorpSouth common
                stock that may be received by executive officers 
                and directors based upon this beneficial 
                ownership......................................        582,521

                Minimum number of shares of BancorpSouth common
                stock that may be received by executive officers 
                and directors based upon this beneficial 
                ownership......................................        430,557

         -------------------------
         (1)      Does not include 3,200 shares of common stock of The First
                  Corporation subject to stock options exercisable on December
                  13, 1998. Includes 1,360.41 shares of common stock of The
                  First Corporation held by such persons as trustees of The
                  First Corporation Employee Stock Ownership Plan and which
                  shares have not been allocated to the participants in such
                  plan. Pursuant to the terms of this plan, the trustees may
                  vote such unallocated shares in their discretion.

        In addition, there are currently options outstanding to purchase up to
3,200 shares of The First Corporation common stock, many of which are held by
directors and executive officers of The First Corporation. These options will be
replaced in the merger with options to purchase a number of shares of
BancorpSouth common stock equal to the product of (1) the number of shares of
The 



                                       10

<PAGE>   14


First Corporation common stock which the options entitle the holder to
acquire, times (2) the exchange ratio in the merger.

         Mr. William C. Kent, who is currently President of The First
Corporation, will become community bank president of the branch locations of
BancorpSouth Bank in the Opelika, Alabama area after the merger. Mr. Kent has
entered into an employment agreement with BancorpSouth Bank that is effective
upon completion of the merger. The employment agreement provides that Mr. Kent
will receive an annual salary of $118,368. In his employment agreement, Mr.
Kent has agreed that he will not compete with BancorpSouth Bank within a
specified area.

DISSENTERS' RIGHTS (PAGE 25)

         Alabama law permits you to dissent from the merger and to have the fair
value of your shares of common stock of The First Corporation paid to you in
cash. To do this, you must follow certain procedures, including filing certain
notices with The First Corporation and refraining from voting your shares in
favor of the merger. If you dissent from the merger, your shares of The First
Corporation common stock will not be exchanged for shares of BancorpSouth common
stock in the merger, and your only right will be to receive the appraised fair
value of your shares of common stock of The First Corporation in cash.

REGULATORY APPROVAL (PAGE 39)

   
         The companies cannot complete the merger unless they obtain the
approval of the Federal Deposit Insurance Corporation. The U.S. Department of
Justice has input into the FDIC's approval process. Once the FDIC has approved
the merger, federal law requires the companies to wait for up to 30 days to
complete the merger, in order to give the Department of Justice the opportunity
to review and object to the merger. BancorpSouth obtained approval from the FDIC
on November 9, 1998. Pursuant to the specific terms of the FDIC approval, the
waiting period will expire on November 24, 1998, 15 days after receipt of such
FDIC approval. 
    

         In addition, the merger is subject to the approval of the Mississippi
Department of Banking and Consumer Finance and the Alabama Banking Department.
The companies have filed all of the required notices with these state regulatory
authorities, and approval of the merger is expected to be received following an
affirmative vote of the shareholders of The First Corporation in favor of the
merger agreement.

         While the companies are not aware of any reason why they should not
obtain the remaining regulatory approvals in a timely manner, they cannot be
certain when they will obtain the approvals or that the companies will obtain
them.

CONDITIONS TO COMPLETION OF THE MERGER (PAGE 45)

         The completion of the merger depends on a number of conditions being
met, including the following:

         1.       Shareholders of The First Corporation approving the merger;

         3.       Receipt of all required regulatory approvals, including that

         4.       The absence of any governmental order blocking completion of 
                  the merger, or of any proceedings by a government body trying
                  to block it;

         5.       Receipt of opinions of legal counsel to each company that the
                  U.S. federal income tax treatment in the merger will generally
                  be as described in this document;

         6.       BancorpSouth being satisfied that the merger will qualify for
                  pooling of interests accounting treatment under applicable
                  accounting standards; and

         7.       Mr. William C. Kent, the President of The First Corporation,
                  entering into a written employment agreement with BancorpSouth
                  Bank.

         In cases where the law permits, a party to the merger agreement could
elect to waive a condition that has not been satisfied and complete the merger
although it is entitled not to. The companies cannot be certain whether or when
any of these conditions will be satisfied (or waived, where permissible), or
that the merger will be completed.

TERMINATION OF THE MERGER AGREEMENT (PAGE 46)

         The companies can agree at any time to terminate the merger agreement
without completing the merger, even if the shareholders of The First Corporation
have already voted to approve it. Also, BancorpSouth can terminate the merger
agreement if the Board of Directors of The First Corporation withdraws, or
modifies in any way adverse to BancorpSouth, its recommendation that its
shareholders approve the merger, or if BancorpSouth's independent certified
public accountants advise BancorpSouth that the merger does not qualify for
pooling of interests accounting treatment.

         Moreover, either company can terminate the merger agreement in the
following circumstances:

         1.       After a final decision by a governmental authority to prohibit
                  the merger, or after the rejection of an application for a
                  governmental approval required to complete the merger (but in
                  the latter case, only after waiting 60 days);

         2.       If the mergers aren't completed by June 30, 1999;

         3.       If the shareholders of The First Corporation do not approve
                  the merger; or

         4.       If the other party violates, in a significant way, any of its
                  representations, warranties, covenants or obligations
                  contained in the merger agreement.

Generally, a party can only terminate the merger agreement in one of the
preceding four situations if that party is not in violation of the merger
agreement or if its violations of the merger agreement are not the cause of the
event permitting termination.

         In addition, if the computed amount of the exchange ratio for shares of
common stock of The First Corporation is less than 7.0879, BancorpSouth can
elect to terminate the merger agreement unless The First Corporation agrees to
lower the minimum exchange ratio amount of 7.7043 to an amount not less than the
computed exchange ratio. This would occur if the average closing price per share
of BancorpSouth common stock used to compute the exchange ratio was more than
about $24.6643. Similarly, if the computed exchange ratio is more than 11.8132,
The First Corporation can elect to terminate the merger agreement unless
BancorpSouth agrees to increase the maximum exchange ratio amount of 10.4235 to
an amount not greater than the computed exchange ratio. This would occur if the
average closing price per share of BancorpSouth common stock used to compute the
exchange ratio was less than about $14.7985. There can be no assurance that
BancorpSouth or The First Corporation would exercise, or refrain from
exercising, their right to terminate the merger agreement under the
circumstances described in this paragraph. BancorpSouth and The First
Corporation could also elect to complete the merger without adjusting the
minimum or maximum exchange ratios.

         For example, if the average closing price of BancorpSouth common stock
was equal to $24.75, the exchange ratio applied to each share of BancorpSouth
common stock would be about 7.06. Since that amount is less than 7.0879,
BancorpSouth would have the right to terminate the merger 



                                       12

agreement unless The First Corporation agrees to decrease the minimum exchange
ratio of 7.7043 to an amount proposed by BancorpSouth that is not less than
7.06. BancorpSouth could elect to waive its right to terminate and complete the
mergers without adjusting the exchange ratio. If the average closing price of
BancorpSouth common stock was equal to $14.50, the exchange ratio applied to
each share of The First Corporation common stock would be about 12.06. Since
that amount is more than 11.8132, The First Corporation would have the right to
terminate the merger agreement unless BancorpSouth agrees to increase the
maximum exchange ratio of 10.4235 to an amount proposed by The First Corporation
that is not greater than 12.06. The First Corporation could elect to waive its
right to terminate and complete the merger without adjusting the exchange ratio.

         The computed exchange ratio amount below which BancorpSouth can elect
to terminate the merger agreement, 7.0879, is less than the minimum exchange
ratio of 7.7043. Therefore, if the computed exchange ratio is less than 7.7043
but not less than 7.0879, then the applicable exchange ratio would be limited to
the minimum exchange ratio of 7.7043 and BancorpSouth would not have the right
to terminate the merger agreement as a result. Similarly, the computed exchange
ratio amount above which The First Corporation can elect to terminate the merger
agreement, 11.8132, is more than the maximum exchange ratio of 10.4235.
Therefore, if the computed exchange ratio is more than 10.4235 but not more than
11.8132, then the applicable exchange ratio would be limited to the maximum
exchange ratio of 10.4235 and The First Corporation would not have the right to
terminate the merger agreement as a result. If the average closing price of
BancorpSouth common stock is viewed as an implied value, this paragraph
demonstrates that shareholders of The First Corporation could actually receive
shares of BancorpSouth common stock with an implied value of less than $174.8178
in exchange for each share of The First Corporation common stock.

BANCORPSOUTH'S OPTION TO PURCHASE THE FIRST CORPORATION COMMON STOCK (PAGE 49)

         To induce BancorpSouth to enter into the merger agreement, The First
Corporation granted a stock option to BancorpSouth to purchase up to 47,822
shares of The First Corporation common stock at a price of $125.00 per share.
The number of shares of The First Corporation common stock that may be acquired
upon exercise of the stock option may not exceed 19.9% of the issued and
outstanding shares of The First Corporation common stock (without counting
shares that are exercisable under the stock option).

         BancorpSouth cannot exercise the stock option unless certain specific
events take place. These events are generally related to a competing transaction
involving a merger, business combination or other acquisition of The First
Corporation or its stock or assets. As of the date of this Prospectus
Supplement/Proxy Statement, the companies are not aware that any event of that
kind has occurred. The stock option could have the effect of discouraging other
companies that might want to combine with or acquire The First Corporation from
doing so. The stock option agreement is attached as Annex D to this Prospectus
Supplement/Proxy Statement.

FORWARD-LOOKING STATEMENTS MAY PROVE INACCURATE (PAGE 83)

   
         This document, and other documents to which you are referred in this
document, contain forward-looking statements that are subject to risks and
uncertainties. These forward-looking statements include information about
possible or assumed future results of the companies' operations or the
performance of the combined companies after the merger. Forward-looking
statements generally include any of the words "believes," "expects,"
"anticipates" or similar expressions. Many possible events or factors could
affect the future financial results and performance of each of the companies and
the combined company after the merger and could cause those results or
performance to differ materially from those expressed in forward-looking
statements. These possible events or factors include the following:
    

   
         1.       Problems or delays in bringing the companies together, either 
                  before or after the merger is consummated;
    

         2.       Legal and regulatory risks and uncertainties;

         3.       Economic, political and competitive forces affecting the
                  companies' businesses, markets, constituencies or securities;
                  and

         4.       Inaccuracies in the companies' analyses of these risks and 
                  forces, and lack of success of strategies developed to deal 
                  with them.

COMPARATIVE UNAUDITED PER SHARE DATA

         The following table shows information, for the periods indicated, about
BancorpSouth's and The First Corporation's historical net income per share,
dividends per share and book value per share. The table also provides similar
information that reflects the merger of BancorpSouth and The First Corporation
(which is referred to as "pro forma" information). In presenting the comparative
pro forma information for certain time periods, it is assumed that The First
Corporation and BancorpSouth had been merged throughout those periods for
accounting and financial reporting purposes (a method which is referred to as
the "pooling of interests" method of accounting). In addition, the table
provides "pro forma equivalent" information for The First Corporation, which was
obtained by multiplying the BancorpSouth and The First Corporation pro forma
amounts by an assumed exchange ratio equal to the midpoint of the range of the
exchange ratio. It is intended to reflect the fact that shareholders will be
receiving more than one share of BancorpSouth common stock for each share of The
First Corporation common stock exchanged in the merger.

                             SELECTED FINANCIAL DATA

         The following tables show summarized unaudited historical consolidated
financial data for BancorpSouth and for The First Corporation and also show
similar pro forma information reflecting the merger of the two companies. The
pro forma information reflects the pooling of interests method of accounting for
the merger of The First Corporation into BancorpSouth. The pro forma information
does not reflect BancorpSouth's pending merger with Merchants Capital
Corporation or the merger of Alabama Bancorp., Inc. into BancorpSouth on October
30, 1998. See "SUMMARY -- The Companies" and "WHERE YOU CAN FIND MORE
INFORMATION."

   
         BancorpSouth and The First Corporation expect to incur merger-related
expenses as a result of combining the companies. The companies also anticipate
that the merger will provide the combined company with financial benefits such
as reduced operating expenses and the opportunity to earn more revenue. However,
none of these anticipated expenses or benefits have been factored into the pro
forma income statement information. For that reason, the pro forma information,
while helpful in illustrating the financial attributes of the combined company
under one set of assumptions, doesn't attempt to predict or suggest future
results. Also, the information set forth for the nine-month period ended
September 30, 1998 does not indicate what the results will be for the full 1998
fiscal year.

         The information in the following tables is based on the historical
financial information of BancorpSouth that has been presented in its prior
filings with the Securities and Exchange Commission (and which has been
incorporated by reference into this Prospectus Supplement/Proxy Statement) and
on the historical financial information of The First Corporation included in
this Prospectus Supplement/Proxy Statement. All of the summary financial
information provided in the following tables should be read in connection with
this historical financial information. See "WHERE YOU CAN FIND MORE
INFORMATION." The financial information as of and for the interim periods ended
September 30, 1998 and 1997 has not been audited and in the respective opinions
of management reflects all adjustments (consisting only of normal recurring
adjustments) necessary to a fair presentation of such data.

                               THE SPECIAL MEETING


GENERAL

         This Prospectus Supplement/Proxy Statement is first being mailed, on or
about __________, 1998, to the holders (the "First Corporation Shareholders") of
shares of common stock, $0.05 par value per share (the "First Corporation Common
Stock"), of The First Corporation, an Alabama corporation ("The First
Corporation").

         This Prospectus Supplement/Proxy Statement is accompanied by a Notice
of Special Meeting from, and form of proxy that is solicited by, the Board of
Directors of The First Corporation (the "First Corporation Board") for use at
the special meeting of First Corporation Shareholders and at any adjournments or
postponements thereof.

         A special meeting of First Corporation Shareholders (the "First
Corporation Special Meeting") is to be held as follows: 

                                ___________, 1998
                            ______ _.m. (local time)
                       The First National Bank of Opelika
                            414 South Seventh Street
                               Opelika, Alabama.

         At the First Corporation Special Meeting, First Corporation
Shareholders will consider and vote upon a proposal to approve and adopt an
Agreement and Plan of Merger, dated as of August 12, 1998 (the "Merger
Agreement"), between The First Corporation and BancorpSouth, Inc., a Mississippi
corporation ("BancorpSouth"), which provides for the merger of The First
Corporation with and into BancorpSouth (the "Merger").

PROXIES

         First Corporation Shareholders may use the accompanying proxy solicited
by the First Corporation Board if any such shareholder is unable to attend the
First Corporation Special Meeting in person or wishes to have his or her shares
voted by proxy even if such shareholder does attend the meeting. First
Corporation Shareholders may revoke any proxy given pursuant to this
solicitation by:

         1.       Delivering to the corporate Secretary of The First Corporation
                  a written notice revoking the proxy prior to the taking of the
                  vote at the First Corporation Special Meeting;

         2.       Delivering a duly executed proxy relating to the same shares 
                  bearing a later date; or

         3.       Attending the meeting and voting in person (attendance at the
                  First Corporation Special Meeting will not in and of itself
                  constitute a revocation of a proxy).

         All written notices of revocation and other communications with respect
to the revocation of proxies should be addressed to the following:

                           The First Corporation
                           P.O. Box 970
                           Opelika, Alabama 36803-0970
                           Attention:  Secretary.

         For a notice of revocation or later proxy to be valid, however, it must
actually be received by The First Corporation prior to the vote of the First
Corporation Shareholders at the First Corporation Special Meeting. All shares
represented by valid proxies received pursuant to this



                                       23

<PAGE>   27



solicitation, and not revoked before they are exercised, will be voted in the
manner specified therein. If no specification is made, the proxies will be voted
in favor of approval of the Merger Agreement.

         The First Corporation is currently unaware of any other matters that
may be presented for action at the First Corporation Special Meeting. If other
matters do properly come before the First Corporation Special Meeting, then
shares represented by proxies will be voted (or not voted) by the persons named
in the proxies in their discretion.

SOLICITATION OF PROXIES

         The cost of soliciting proxies from First Corporation Shareholders will
be borne by the parties to the Merger Agreement. In addition to the solicitation
of proxies by mail, The First Corporation will request banks, brokers and other
record holders to send proxies and proxy material to the beneficial owners of
the stock and secure their voting instructions, if necessary. The First
Corporation will reimburse such record holders for their reasonable expenses in
so doing. If necessary, The First Corporation may also use several of its
regular employees, who will not be specially compensated, to solicit proxies
from First Corporation Shareholders, either personally or by telephone,
telegram, facsimile or special delivery letter.

RECORD DATE AND VOTING RIGHTS

         The First Corporation Board has fixed ____________, 1998 as the record
date (the "First Corporation Record Date") for the determination of the First
Corporation Shareholders entitled to receive notice of and to vote at the First
Corporation Special Meeting. Accordingly, only First Corporation Shareholders of
record at the close of business on the First Corporation Record Date will be
entitled to notice of and to vote at the First Corporation Special Meeting. At
the close of business on the First Corporation Record Date, there were ________
shares of First Corporation Common Stock entitled to vote at the First
Corporation Special Meeting held by approximately ____ holders of record.

         As of the First Corporation Record Date, there were ______ shares of
First Corporation Common Stock held of record by trustees of The First
Corporation Employee Stock Ownership Plan (the "First Corporation ESOP").
Pursuant to the terms of the First Corporation ESOP, each participant in the
First Corporation ESOP may direct the trustees of the First Corporation ESOP to
vote his or her allocated shares for or against a transaction such as the
Merger. Unless so directed, such allocated shares are not to be voted. The
trustees may vote unallocated shares in their discretion. There were 1,360.41 of
these unallocated shares of First Corporation Common Stock as of the First
Corporation Record Date.

         The presence, in person or by proxy, of shares of First Corporation
Common Stock representing a majority of the votes entitled to be cast at the
First Corporation Special Meeting is necessary to constitute a quorum. Each
share of First Corporation Common Stock outstanding on the First Corporation
Record Date entitles its holder to one vote as to the approval of (1) the Merger
Agreement, and (2) any other proposal that may properly come before the First
Corporation Special Meeting.

         For purposes of determining the presence or absence of a quorum for the
transaction of business, The First Corporation will count shares of First
Corporation Common Stock present in person at the First Corporation Special
Meeting but not voting, and shares of First Corporation Common Stock for which
it has received proxies but with respect to which holders of such shares have
abstained, as present at the First Corporation Special Meeting. Abstentions are
counted as present at the First Corporation Special Meeting for purposes of
determining whether a quorum exists and have the effect of a vote "against" any
matter as to which they are specified. Proxies submitted by brokers that do not
indicate a vote for some or all of the proposals because they don't have
discretionary voting authority and have not received instructions as to how to
vote on those proposals (so-called "broker non-votes") will be counted as
present at the First Corporation Special 




                                       24

<PAGE>   28


Meeting for purposes of determining whether a quorum exists and have the effect
of a vote "against" any proposal as to which instructions on how to vote were
not provided.

         Under the Alabama Business Corporation Act (the "ABCA"), approval of
the Merger Agreement requires the affirmative vote of the holders of two-thirds
of all votes entitled to be cast on the Merger Agreement at the First
Corporation Special Meeting. Because approval of the Merger Agreement requires
the affirmative vote of the holders of two-thirds of the outstanding shares of
First Corporation Common Stock, abstentions and broker non-votes will have the
same effect as negative votes. Accordingly, the First Corporation Board urges
First Corporation Shareholders to complete, date and sign the accompanying proxy
and return it promptly in the enclosed, postage-paid envelope.

        As of the First Corporation Record Date, about 55,885.41 shares of First
Corporation Common Stock, or about 24.06% of the shares entitled to vote at the
First Corporation Special Meeting, were beneficially owned by directors and
executive officers of The First Corporation. This beneficial ownership does not
include 3,200 shares of common stock of The First Corporation subject to stock
options exercisable on December 13, 1998, but does include 1,360.41 shares of
First Corporation Common Stock held by such persons as trustees of the First
Corporation ESOP and which shares have not been allocated to the participants in
the First Corporation ESOP. Pursuant to the terms of the First Corporation ESOP,
the trustees may vote such unallocated shares in their discretion. It is
expected that each director and executive officer of The First Corporation will
vote the shares of First Corporation Common Stock beneficially owned by him or
her for approval of the Merger Agreement.

RECOMMENDATION OF THE BOARD OF DIRECTORS

         The First Corporation Board has unanimously approved the Merger
Agreement. The First Corporation Board believes that the Merger is in the best
interests of The First Corporation and First Corporation Shareholders and
unanimously recommends that First Corporation Shareholders vote "FOR" approval
and adoption of the Merger Agreement. The conclusion of The First Corporation
Board with respect to the Merger is based on a number of factors, including the
receipt of a fairness opinion from its financial advisor. See "THE MERGER --
Reasons for the Merger; Recommendation of the Board of Directors."

DISSENTERS' RIGHTS

         Any holder of First Corporation Common Stock is entitled to dissenters'
rights under Article 13 of the ABCA ("Article 13") as a result of the Merger.
All references in Article 13 and in this summary to a "First Corporation
Shareholder" are to the record holders of First Corporation Common Stock who
have asserted their dissenters' rights. A person having a beneficial interest in
shares of First Corporation Common Stock that are held of record in the name of
another person, such as a broker or nominee, must act promptly to cause the
record holder to follow the steps summarized below properly and in a timely
manner to perfect whatever dissenters' rights the beneficial owner may have.

         The following discussion is not a complete statement of the law
pertaining to dissenters' rights under the ABCA. Any First Corporation
Shareholder who wishes to exercise such dissenters' rights, or who wishes to
preserve his or her right to do so, should review Article 13, a copy of which is
attached as Annex B to this Prospectus Supplement/Proxy Statement, and the
following discussion carefully. Failure to timely and properly comply with the
procedures specified will result in the complete loss of dissenters' rights
under the ABCA.

         The availability of dissenters' rights is conditioned upon compliance
with applicable law. Accordingly, any First Corporation Shareholder who wishes
to dissent from the Merger and receive the value of his or her First Corporation
Common Stock in cash should consult with his or her counsel.

         A First Corporation Shareholder's failure to vote against the Merger
Agreement will not constitute a waiver of his or her appraisal or similar
rights. A vote against the Merger Agreement will not be deemed to satisfy all of
the notice requirements under Alabama law with respect to appraisal rights.

         In order to be eligible to exercise the right to dissent, a First
Corporation Shareholder must:

         1.       Give notice in writing to The First Corporation prior to the
                  vote on the Merger Agreement that such First Corporation
                  Shareholder intends to demand payment for his or her shares of
                  First Corporation Common Stock if the Merger is consummated;
                  and
  
         2.       Not vote such shares of First Corporation Common Stock in 
                  favor of the Merger Agreement.

         If the Merger is approved at the First Corporation Special Meeting,
BancorpSouth must deliver a written notice (the "Dissenters' Notice") to all
First Corporation Shareholders who satisfied the requirements referred to in the
preceding paragraph. BancorpSouth must deliver the Dissenters' Notice within ten
days after the Effective Date. This notice must:

         1.       State where the payment demand ("Payment Demand") must be 
                  sent and where First Corporation Common Stock certificates 
                  must be deposited;

         2.       Inform holders of shares of First Corporation Common Stock to
                  what extent transfer of the shares will be restricted after
                  the payment demand is received;

         3.       Supply a form for demanding payment that includes the date of
                  the first announcement to the news media or to First
                  Corporation Shareholders of the terms of the Merger, and the
                  First Corporation Shareholder asserting dissenters' rights
                  must certify whether he or she acquired beneficial ownership
                  of the shares of First Corporation Common Stock before that
                  date;

         4.       Set a date by which BancorpSouth must receive the Payment 
                  Demand, which date may not be fewer than 30 nor more than 60
                  days after the date the Dissenters' Notice is delivered; and

         5.       Be accompanied by a copy of Article 13 of the ABCA.

         A shareholder who is sent a Dissenters' Notice must demand payment in
accordance with the terms of the Dissenters' Notice and certify that he or she
acquired beneficial ownership of the shares of First Corporation Common Stock
before the date required to be set forth in the Dissenters' Notice. The
dissenting shareholder must, within 20 days of making such demand for payment,
submit his or her stock certificates to BancorpSouth. BancorpSouth shall make a
notation on the shareholder's stock certificates indicating that a demand for
payment has been made and shall return such certificates to the shareholder.
Failure to submit First Corporation Common Stock certificates to BancorpSouth
for notation will result in the forfeiture by such shareholder of the right to
receive payment for such shares, unless a court of competent jurisdiction
otherwise directs for good and sufficient cause.

         A First Corporation Shareholder who demands payment and deposits his or
her stock certificates in accordance with the previous paragraph retains all
other rights of a First Corporation Shareholder until those rights are canceled
or modified by the consummation of the Merger.

         A shareholder who does not demand payment or deposit his or her stock
certificates where required, in each case by the date set forth in the
Dissenters' Notice, is not entitled to payment for his or her shares of First
Corporation Common Stock.



                                       26

<PAGE>   30



         As soon as the Merger is effective, or upon receipt of a Payment
Demand, BancorpSouth must offer to pay each dissenting First Corporation
Shareholder who has complied with his or her obligations under Section
10-2B-13.23 of the ABCA the amount BancorpSouth estimates to be the fair value
of such First Corporation Shareholder's shares of First Corporation Common
Stock, plus accrued interest. This offer of payment must be accompanied by the
following:

         1.       The First Corporation's consolidated balance sheet as of the
                  end of a fiscal year ending not more than 16 months before the
                  date of the offer of payment, an income statement for that
                  year and the latest available interim financial statements, if
                  any;

         2.       A statement of BancorpSouth's estimate of the fair value of 
                  the shares of First Corporation Common Stock;

         3.       An explanation of how the interest was calculated;

         4.       A statement of the dissenting shareholder's right to demand 
                  payment under ABCA Section 10-2B-13.28; and

         5.       A copy of Article 13 of the ABCA.

         Each dissenter who agrees to accept BancorpSouth's offer of payment in
full satisfaction of his or her demand must surrender to BancorpSouth his or her
certificate or certificates in accordance with the terms of the Dissenters'
Notice. Upon receipt of the certificate or certificates, BancorpSouth will pay
the dissenter the fair value of his or her shares, plus accrued interest.

         BancorpSouth may elect to withhold an offer of payment from a dissenter
who was not the beneficial owner of the shares of First Corporation Common Stock
on the date set forth in the Dissenters' Notice as the date of the first
announcement to news media or to First Corporation Shareholders of the terms of
the Merger. To the extent BancorpSouth does elect to withhold payment under
those circumstances, BancorpSouth must estimate, after consummation of the
Merger, the fair value of the shares of First Corporation Common Stock, plus
accrued interest, and pay this amount to each dissenting First Corporation
Shareholder who agrees to accept it in full satisfaction of such shareholder's
demand. BancorpSouth must send with its offer:

         1.       A statement of BancorpSouth's estimate of the fair value of
                  the shares of First Corporation Common Stock;

         2.       An explanation of how the interest was calculated; and

         3.       A statement of the dissenting First Corporation Shareholder's
                  right to demand payment pursuant to ABCA Section 10-2B-13.28.

         A dissenting shareholder may notify BancorpSouth in writing of such
shareholder's own estimate of the fair value of his or her shares of First
Corporation Common Stock and amount of interest due. The dissenting shareholder
may demand payment of such estimate (less any payments previously made) or
reject BancorpSouth's offer and demand payment of the fair value of such shares
and interest due, if:

         1.       The dissenting shareholder believes that the amount offered to
                  be paid by BancorpSouth is less than the fair value of such
                  shares or that the interest due is incorrectly calculated;

         2.       BancorpSouth fails to make an offer of payment within 60 days 
                  after the date set forth demanding payment; or



                                       27

<PAGE>   31


         3.       BancorpSouth, having failed to take the proposed corporate
                  action, does not release the transfer restrictions imposed on
                  the shares of First Corporation Common Stock within 60 days
                  after the date set for demanding payment.

However, a dissenting shareholder waives the right to demand such payment unless
the shareholder notifies BancorpSouth of such demand in writing within 30 days
after BancorpSouth offered payment for the shareholder's shares of First
Corporation Common Stock.

         If BancorpSouth does not take the proposed corporate action within 60
days after the date set for demanding payment of such dissenting shareholder's
shares of First Corporation Common Stock, BancorpSouth must release the transfer
restrictions imposed on such shares of First Corporation Common Stock. If
BancorpSouth, after releasing the transfer restrictions imposed upon the
shareholder's shares of First Corporation Common Stock, takes the proposed
corporate action, a new Dissenters' Notice must be delivered to the shareholder
and the Payment Demand procedure discussed above must be repeated.

         If a demand for payment under Section 10-2B-13.28 of the ABCA remains
unsettled, BancorpSouth must commence a proceeding within 60 days after
receiving the Payment Demand and petition the court to determine the fair value
of the shares of First Corporation Common Stock and accrued interest. If
BancorpSouth does not commence this proceeding within this 60-day period, it
must pay each dissenting First Corporation Shareholder whose demand remains
unsettled the amount demanded.

         BancorpSouth must commence any such proceeding relating to First
Corporation Common Stock in the circuit court of Lee County, Alabama (the
"Circuit Court"). BancorpSouth must make all dissenting shareholders, whose
demands remain unsettled, parties to the proceeding and all parties must be
served with a copy of the petition. After the dissenting shareholders have been
properly served a copy of the petition, BancorpSouth must deposit with the clerk
of the Circuit Court an amount sufficient to pay unsettled claims of all
dissenting shareholders in an amount equal to BancorpSouth's prior estimate of
fair value, plus accrued interest. The Circuit Court may appoint one or more
persons as appraisers to receive evidence and recommend a decision on the
question of fair value. The appraisers will have the powers described in the
order appointing them, or in any amendment to it. Dissenting shareholders are
entitled to the same discovery rights as parties to other civil proceedings.

         Each dissenting First Corporation Shareholder made a party to the
proceeding is entitled to judgment for the amount the Circuit Court finds as the
fair value of such shareholder's shares of First Corporation Common Stock, plus
interest.

         The Circuit Court, in an appraisal proceeding, must determine all costs
of the proceeding, including the compensation and expense of appraisers
appointed by the Circuit Court. The Circuit Court must assess these costs
against BancorpSouth, except that the Circuit Court may assess costs against all
or some of the dissenting shareholders, in amounts the Circuit Court finds
equitable, to the extent the court finds the dissenting shareholders acted
arbitrarily, vexatiously or not in good faith in demanding payment.

         The Circuit Court may also assess the reasonable fees and expenses of
counsel and experts for the respective parties, in amounts the court finds
equitable, as follows:

         1.       Against BancorpSouth and in favor of any and all dissenting
                  shareholders if the court finds that BancorpSouth did not
                  substantially comply with the requirements of ABCA Sections
                  10-2B-13.20 through 10-2B-13.28; or

         2.       Against either BancorpSouth or a dissenting shareholder, in
                  favor of any other party, if the court finds that the party
                  against whom the fees and expenses are assessed 



                                       28
<PAGE>   32

                  acted arbitrarily, vexatiously or not in good faith with 
                  respect to the rights provided by Article 13 of the ABCA.

         If the Circuit Court finds that the services of counsel for any
dissenting shareholder were of substantial benefit to other dissenting
shareholders similarly situated, and that the fees for those services should not
be assessed against BancorpSouth, the Circuit Court may award to those counsel
reasonable fees to be paid out of the amounts awarded to the dissenting
shareholders who were benefited.

                                   THE MERGER


DESCRIPTION OF THE MERGER

         At the effective time of the Merger (the "Effective Time"), The First
Corporation will merge into BancorpSouth, the separate corporate existence of
The First Corporation will cease and BancorpSouth will be the surviving
corporation (the "Surviving Corporation"). BancorpSouth will continue to exist
as a Mississippi corporation. In addition, The First National Bank of Opelika, a
national banking association and a wholly-owned subsidiary of The First
Corporation ("First National Bank"), will merge into BancorpSouth Bank, a
Mississippi state bank corporation and a wholly-owned subsidiary of
BancorpSouth, and BancorpSouth Bank will be the surviving bank (the "Surviving
Bank"). BancorpSouth Bank shall continue its existence under the laws of the
State of Mississippi. Subject to the satisfaction or waiver of certain
conditions set forth in the Merger Agreement, the Merger will become effective
upon the filing of articles of merger (the "Articles of Merger") in the offices
of the Secretary of State of the State of Alabama and the offices of the
Secretary of State of the State of Mississippi in accordance with the ABCA and
the Mississippi Business Corporation Act (the "MBCA"). See "THE MERGER AGREEMENT
- -- Conditions to the Merger."

         The Merger will have the effects set forth in Sections 79-4-11.01 and 
81-5-85 of the Mississippi Code, Sections 10-2B-11.01 et seq. of the ABCA and
Sections 5-13B-20 et seq. of the Alabama Banking Code ("ABC").

         BancorpSouth's amended and restated articles of incorporation and
bylaws as in effect at the Effective Time will be those of the Surviving
Corporation, while BancorpSouth Bank's amended and restated articles of
incorporation and bylaws will be those of the Surviving Bank.

         At the Effective Time, automatically by virtue of the Merger and
without any action on the part of any party or shareholder, each share of First
Corporation Common Stock issued and outstanding immediately prior to the
Effective Time will become and be converted into the right to receive shares of
common stock, $2.50 par value per share (the "BancorpSouth Common Stock"), of
BancorpSouth in the amounts set forth below. However, shares with respect to
which appraisal or dissenters' rights have been properly demanded in accordance
with Article 13 of the ABCA ("Dissenting Shares"), or held by The First
Corporation or any of its subsidiaries, in each case, other than shares held in
a fiduciary capacity ("Trust Account Shares") or in respect of a debt previously
contracted ("DPC Shares") will not be converted into BancorpSouth Common Stock
automatically at the Effective Time of the Merger. If, prior to the Effective
Time, shares of BancorpSouth Common Stock are changed into a different number or
class of shares due to any reclassification, recapitalization, split-up,
combination, exchange of shares or readjustment, or if a stock dividend is
declared on the shares of First Corporation Common Stock with a record date
prior to the Effective Time, the exchange ratio will be adjusted accordingly.

         The market price of BancorpSouth Common Stock is expected to fluctuate
between the date of this Prospectus Supplement/Proxy Statement, the date on
which the Merger is completed and thereafter, and may decrease. Each of the
exchange ratios is flexible within a specified range in order to assure that,
within the range, the implied market value of BancorpSouth Common Stock that you
receive in connection with the Merger (i.e., $174.8178 per share of First
Corporation Common Stock) will remain the same despite fluctuations in the
market price between the date of this Proxy Statement/Prospectus Supplement and
the Effective Time. For further information concerning the historical market
prices of BancorpSouth Common Stock and First Corporation

<PAGE>   34

Common Stock, see "PRICE RANGE OF COMMON STOCK AND DIVIDENDS." No assurance can
be given concerning the market price of BancorpSouth Common Stock before or
after the Effective Time.

         For purposes of calculating the exchange ratio:

         1.       "Exchange Ratio" means the quotient, rounded to the nearest 
                  1/10,000, equal to (x) $174.8178, divided by (y) the Average
                  Closing Price (as defined in the following paragraph);

         2.       "Average Closing Price" means the average closing prices of
                  BancorpSouth Common Stock as reported on the New York Stock
                  Exchange for the ten consecutive full trading days in which
                  shares of BancorpSouth Common Stock are traded on the New York
                  Stock Exchange ending at the close of trading on the third
                  business day prior to the date on which the Merger is
                  completed.

         In the event that, without giving effect to the minimum and maximum
exchange ratio limitations, the exchange ratio computed in accordance with the
formula in the Merger Agreement exceeds 11.8132, The First Corporation may, at
its option and without penalty, terminate the Merger Agreement by giving prior
written notice to BancorpSouth, unless within 24 hours after such notice is
given, BancorpSouth agrees to increase the maximum exchange ratio of 10.4235 to
an amount proposed by The First Corporation that is not greater than the
computed amount of the exchange ratio. If, however, the computed exchange ratio
is less than 7.0879, BancorpSouth may, at its option and without penalty,
terminate the Merger Agreement by giving prior written notice to The First
Corporation, unless within 24 hours after such notice is given, The First
Corporation agrees to lower the minimum exchange ratio of 7.7043 to an amount
proposed by BancorpSouth that is not less than the computed exchange ratio. See
"THE MERGER AGREEMENT -- Termination of the Merger Agreement."

         At the Effective Time, First Corporation Shareholders, other than those
who perfect dissenters' rights under the ABCA (see "THE SPECIAL MEETING --
Dissenters' Rights"), will cease to be, and will have no rights as, First
Corporation Shareholders, other than to receive the consideration to be issued
to them in the Merger (the "Merger Consideration"). After the Effective Time,
there will be no transfers on the stock transfer books of The First Corporation
of shares of First Corporation Common Stock. If, after the Effective Time, stock
certificates representing shares of First Corporation Common Stock are presented
for transfer to SunTrust Bank, Atlanta (the "Exchange Agent"), they will be
canceled and exchanged for certificates representing shares of BancorpSouth
Common Stock as provided in the Merger Agreement.

         A common stock purchase right attaches to, and trades with, each share
of BancorpSouth Common Stock, including the shares of BancorpSouth Common Stock
that First Corporation Shareholders will receive in the Merger. Upon the
occurrence of certain events (including the acquisition of, or tender offer for,
20% or more of the outstanding shares of BancorpSouth Common Stock by any person
or entity), each of these common stock purchase rights (other than those held by
the person acquiring the shares or making the tender offer) will entitle the
holder of the right to purchase one share of BancorpSouth Common Stock for a
price per share equal to 50% of the then market price. These rights, which are
issued under BancorpSouth's shareholder rights plan (which is commonly referred
to as a "poison pill"), may make it more difficult for any person or entity to
acquire control of BancorpSouth without the approval of BancorpSouth's Board of
Directors.

         At the Effective Time, all shares of First Corporation Common Stock
held by The First Corporation or its subsidiaries, other than Trust Account
Shares or DPC Shares, will be canceled and will cease to exist, and no
BancorpSouth Common Stock or other consideration will be delivered in exchange
for such shares. Also at the Effective Time, all shares of BancorpSouth Common
Stock held by The First Corporation or its subsidiaries, other than Trust
Account Shares or DPC Shares, will 




                                       31

<PAGE>   35


become treasury stock and all other shares of BancorpSouth Common Stock
outstanding as of the Effective Time will remain outstanding.

         Dissenting Shares will not be converted into the right to receive, or
be exchangeable for, the Merger Consideration. Instead, the holders of
Dissenting Shares will be entitled to payment of the appraised value of the
Dissenting Shares in accordance with Article 13 of the ABCA. However, if any
holder of Dissenting Shares subsequently delivers a written withdrawal of their
demand for appraisal, or if any holder fails to establish his or her entitlement
to dissenters' rights under Article 13 of the ABCA, the holder will forfeit the
right to appraisal and his or her shares will be deemed to have been converted
into the right to receive, and to have become exchangeable for, the Merger
Consideration. See "THE SPECIAL MEETING -- Dissenters' Rights."

BACKGROUND OF THE MERGER

         During the period from 1983 to late 1997, management of The First
Corporation received several unsolicited inquiries from several large regional
financial institutions or their representatives regarding a possible business
combination with The First Corporation and/or the First National Bank. In late
1985, the First Corporation Board received a formal expression of interest from
a financial institution. After thorough consideration, however, the First
Corporation Board decided to remain independent and declined to entertain any
further discussions with that potential acquirer. With that one exception, none
of the unsolicited inquiries received by The First Corporation during this
time-frame resulted in any meaningful discussions with management of The First
Corporation regarding a possible business combination, and no formal
negotiations were conducted.

         During the period from late 1997 through early 1998, management of The
First Corporation received additional unsolicited inquiries from two financial
institutions, each of whom expressed an interest in pursuing a possible business
combination with The First Corporation. At its regular meeting on June 15, 1998,
the First Corporation Board decided to schedule informal meetings between
representatives of these financial institutions and the First Corporation Board.
These meetings were scheduled and held on June 22, 1998 and June 23, 1998.

         Given this renewed level of interest in The First Corporation, on June
18, 1998 the First Corporation Board engaged the independent investment advisory
firm of Alex Sheshunoff & Co. Investment Banking ("Sheshunoff") to assist the
First Corporation Board in establishing a reasonable value of the company and to
assist the First Corporation Board in soliciting additional expressions of
interest regarding a business combination with The First Corporation.

         Following its engagement, Sheshunoff promptly contacted six other
financial institutions (including BancorpSouth) to solicit additional
expressions of interest in acquiring The First Corporation. Sheshunoff was
familiar with BancorpSouth, and BancorpSouth had indicated an interest in
expansion. Three of the six financial institutions contacted by Sheshunoff,
including BancorpSouth, responded positively to such solicitation. The First
Corporation Board, with the assistance of Sheshunoff, considered expressions of
interest received from five financial institutions (including BancorpSouth, two
other financial institutions that expressed interest in response to contacts
made by Sheshunoff and the two financial institutions that had expressed
interest prior to June 18, 1998).

         Following an evaluation of the expressions of interest, the First
Corporation Board determined that offers received from three of the five
institutions were not attractive enough, from a financial perspective, to
warrant further consideration. The First Corporation Board authorized the two
remaining institutions, including BancorpSouth, to conduct a due diligence
review with respect to The First Corporation.

         On June 30, 1998, representatives of Sheshunoff contacted Mr. Aubrey B.
Patterson, Chairman and Chief Executive Officer of BancorpSouth, to determine
BancorpSouth's interest in 



                                       32

<PAGE>   36



pursuing a possible business combination with The First Corporation. The parties
discussed the banking industry generally and the business and operating
philosophies of their respective companies. At the conclusion of the
conversation, BancorpSouth agreed to meet with management of The First
Corporation in Opelika, Alabama on July 6, 1998 to discuss the possibility of a
business combination with total consideration in the range of 2.75 times The
First Corporation's book value.

         On July 6, 1998, Mr. Larry R. Mathews (who was then President of 
Alabama Bancorp., Inc., which had recently entered into a merger agreement with
BancorpSouth), Mr. Patterson and Mr. L. Nash Allen, Jr., Treasurer and Chief
Financial Officer of BancorpSouth, flew to Opelika, Alabama and made a
presentation to the First Corporation Board. The presentation was general in
nature and consisted primarily of an introduction to BancorpSouth.

         On July 7, 1998, Sheshunoff informed BancorpSouth that the First
Corporation Board was interested in continuing its discussions with BancorpSouth
and would permit BancorpSouth to perform a due diligence review upon the
submission of a statement of interest, which would contain a range of proposed
prices. On July 14, 1998, Mr. Patterson contacted representatives of Sheshunoff
concerning the requested expression of interest regarding The First Corporation.
BancorpSouth proposed an acquisition value of approximately 2.72 times net book
value or an aggregate value of approximately $40.8 million.

         On July 17, 1998, representatives of Sheshunoff again contacted
BancorpSouth to provide an update regarding the status of its offer to acquire
The First Corporation. Sheshunoff indicated that BancorpSouth's proposal was
better from a financial point of view than the other proposal that was under
consideration by the First Corporation Board. Following completion of its due
diligence review of The First Corporation, BancorpSouth increased the amount of
its offer such to an aggregate value of approximately $41.4 million.

         Upon completion of due diligence and finalization of offers, members of
the First Corporation Board determined that BancorpSouth's offer was the most
attractive to The First Corporation and its shareholders. This determination was
based principally on the economics of the proposed transaction, the cultural fit
between the two organizations and BancorpSouth's reputation as a
community-oriented financial institution. Discussions with the other financial
institution ceased, and The First Corporation and BancorpSouth began to
negotiate a merger agreement.

         Between July 29, 1998 and August 11, 1998, representatives of
BancorpSouth and The First Corporation engaged in discussions and negotiations
with respect to the Merger Agreement and a Stock Option Agreement, dated as of
August 12, 1998, between BancorpSouth and The First Corporation (the "Stock
Option Agreement"). During negotiations, certain issues, including issues
relating to the treatment of employee stock options, were resolved to the
satisfaction of both parties. Sheshunoff also provided due diligence support on
behalf of The First Corporation with respect to BancorpSouth during this period.

         On August 12, 1998, the First Corporation Board held a special meeting
to consider the proposed transaction with BancorpSouth. At this meeting,
representatives of Sheshunoff and special legal counsel outlined the terms and
conditions of the proposed transaction. Special counsel advised the First
Corporation Board of its fiduciary duty to the shareholders of The First
Corporation in the context of evaluating the terms of the transaction.
Representatives of Sheshunoff also summarized its findings with respect to the
due diligence investigation of BancorpSouth, explained the financial terms of
the proposed transaction with BancorpSouth and discussed in detail the
methodologies and considerations underlying its analysis. Sheshunoff then
delivered its oral opinion as to the fairness, from a financial point of view,
that the shareholders of The First Corporation will receive in the transaction.
Members of the First Corporation Board asked management of The First Corporation
and Sheshunoff detailed questions and then deliberated upon the merits of the
transaction. Thereafter, the First Corporation Board approved the Merger, the
Merger Agreement and the Stock Option Agreement. Later that day, both parties
executed the Merger Agreement and the Stock

Option Agreement. On August 26, 1998, the Board of Directors of BancorpSouth
(the "BancorpSouth Board") ratified the Merger Agreement and approved the
Merger.

REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS

         The BancorpSouth Board believes that the market areas of The First
Corporation and First National Bank are comparable to certain of BancorpSouth's
existing market areas. In addition, it perceives that economies of scale and
cost savings available through combining administrative functions and increased
competitiveness resulting from combined marketing efforts and budgets should
significantly enhance the operations and financial results of BancorpSouth and
BancorpSouth Bank. In addition, the BancorpSouth Board believes that the Merger
should strengthen the ability of First National Bank (as a part of BancorpSouth
Bank) to compete and be successful in its existing markets since BancorpSouth
Bank offers services that are not currently available to customers of First
National Bank and possesses technology that is not currently possessed by First
National Bank.

         As previously noted, The First Corporation Board deliberated and
approved the Merger Agreement at a meeting of the First Corporation Board held
on August 12, 1998. In reaching its determination to approve and adopt the
Merger Agreement, the First Corporation Board consulted with The First
Corporation's management and financial and legal advisors, and considered a
number of factors. The following is a discussion of the information and factors
considered by the First Corporation Board in reaching this determination. This
discussion is not intended to be exhaustive but includes all of the material
factors considered by the First Corporation Board. In the course of its
deliberations with respect to the Merger, the First Corporation Board discussed
the anticipated impact of the Merger on The First Corporation, First Corporation
Shareholders and various other constituencies. The First Corporation Board could
not identify any material disadvantages expected to result from the Merger
during these discussions. In reaching its determination to approve and recommend
the Merger, the First Corporation Board did not assign any relative or specific
weights to the factors considered in reaching such determination, and individual
members of the First Corporation Board may have given differing weights to
different factors.

         The following include the material factors that were considered by the
First Corporation Board:

         1.       Its review, based in part on presentations by The First
                  Corporation's management and financial advisor, of:

                  (i)   the business, operations, technology, dividends,
                        financial condition and earnings of BancorpSouth on an
                        historical and a prospective basis and of the combined
                        company on a pro forma basis,

                  (ii)  the historical stock price performance of BancorpSouth
                        Common Stock, and

                  (iii) the potential impact on the market value of BancorpSouth
                        Common Stock following the Merger;

         2.       The resulting relative interests of First Corporation 
                  Shareholders in the common stock of the combined companies
                  following the Merger;

         3.       The fact that the Merger would allow First Corporation
                  Shareholders to become shareholders in a well-capitalized
                  company, whose stock is traded on the New York Stock Exchange
                  with sufficient trading volume to provide liquidity for
                  shareholders;

         4.       The presentations of Sheshunoff to the First Corporation
                  Board, the financial information reviewed by Sheshunoff at the
                  meeting of the First Corporation Board held on August 12,
                  1998, and the opinion of Sheshunoff rendered on October 30,



                                       34

<PAGE>   38


                  1998, in which Sheshunoff opined that, as of October 30, 1998
                  and based upon and subject to the procedures followed,
                  assumptions made, matters considered and limitations on the
                  analyses undertaken, the calculation of the exchange ratio
                  provided in the Merger Agreement was fair from a financial
                  point of view to First Corporation Shareholders (see
                  "--Fairness Opinion");

         5.       The process conducted by The First Corporation's management
                  and financial advisor in exploring and determining the
                  potential value which could be realized by First Corporation
                  Shareholders in a business combination transaction (which
                  included contacting the bank holding companies determined to
                  be the most likely to be interested in, and financially and
                  otherwise capable of, engaging in a business combination
                  transaction with The First Corporation and First National
                  Bank, reviewing the terms of the proposals received from such
                  bank holding companies and determining that the indicated
                  value of the exchange ratios in the BancorpSouth proposal was
                  higher as of August 12, 1998 than the indicated values of the
                  per share consideration offered in other submitted proposals)
                  (see "--Background of the Merger");

         6.       The terms of the Merger Agreement and the Merger, including
                  the amount and form of consideration to be received by First
                  Corporation Shareholders in the Merger, and the expectation
                  that the Merger will be a tax-free transaction to The First
                  Corporation, First Corporation Shareholders and BancorpSouth
                  to the extent First Corporation Shareholders receive shares of
                  BancorpSouth Common Stock;

         7.       The current and prospective economic and competitive
                  environment facing the financial services industry generally,
                  and The First Corporation in particular, including the
                  continuing consolidation in the industry and the increasing
                  importance of operational scale and financial resources in
                  maintaining efficiency, remaining competitive and capitalizing
                  on technological developments;

         8.       Its review, based in part on the presentations of Sheshunoff,
                  of alternatives to the Merger for enhancing shareholder value,
                  the range of possible values to First Corporation Shareholders
                  obtainable through implementation of such alternatives and the
                  timing and likelihood of actually achieving such value;

         9.       The belief of the First Corporation Board that alternatives to
                  the Merger were not likely to result in greater value for
                  First Corporation Shareholders than the value to be realized
                  in the Merger based upon the First Corporation Board's review
                  and consideration of, among other things variables relating to
                  the ability to continue to generate revenue growth, improved
                  profitability and superior stockholder returns on a
                  stand-alone basis and the availability of attractive
                  acquisition opportunities for The First Corporation;

         10.      The general impact that the Merger could be expected to have
                  on the constituencies served by The First Corporation,
                  including its customers, employees and communities;

         11.      The anticipated cost savings, operating efficiencies and
                  opportunities for revenue enhancement available to the
                  combined companies from the Merger, and the likelihood of the
                  foregoing being achieved following consummation of the Merger;

         12.      The fact that Mr. William C. Kent, President of The First
                  Corporation, would serve as community bank president of the
                  branch locations of BancorpSouth Bank in the Opelika, Alabama
                  area following the Merger, and that the directors and officers
                  of The First Corporation might otherwise be deemed to have
                  interests in the Merger 



                                       35

<PAGE>   39


                  other than their interests generally as First Corporation 
                  Shareholders (see "-- Interests of Certain Persons in the 
                  Merger"); and

         13.      The terms of the Stock Option Agreement between BancorpSouth
                  and The First Corporation, including the risk that the Stock
                  Option Agreement might discourage third parties from offering
                  to acquire The First Corporation by increasing the cost of
                  such an acquisition while recognizing that the execution of
                  the Stock Option Agreement was a condition to BancorpSouth's
                  willingness to enter into the Merger Agreement (see "THE
                  MERGER AGREEMENT -- Stock Option Agreement").


         BASED ON A THOROUGH EVALUATION OF THESE FACTORS, THE FIRST CORPORATION
BOARD BELIEVES THE MERGER IS IN THE BEST INTERESTS OF THE FIRST CORPORATION AND
FIRST CORPORATION SHAREHOLDERS. THE FIRST CORPORATION BOARD UNANIMOUSLY
RECOMMENDS THAT FIRST CORPORATION SHAREHOLDERS VOTE "FOR" APPROVAL AND ADOPTION
OF THE MERGER AGREEMENT.

FAIRNESS OPINION

   
         The First Corporation retained Sheshunoff to provide its opinion of the
fairness, from a financial viewpoint, of the Merger Consideration to be received
by First Corporation Shareholders in connection with the Merger with
BancorpSouth. As part of its investment banking business, Sheshunoff is
regularly engaged in the valuation of securities in connection with mergers and
acquisitions and valuations for estate, corporate and other purposes. The First
Corporation Board retained Sheshunoff based upon its experience as a financial
advisor in mergers and acquisitions of financial institutions and its knowledge
of financial institutions. On August 12, 1998, Sheshunoff rendered its oral
opinion that, as of such date, the Merger Consideration was fair, from a
financial point of view, to First Corporation Shareholders. Sheshunoff rendered
its written fairness opinion letter ("Opinion Letter") as of October 30, 1998
and is updated herein as of November 19, 1998.
    

         The full text of Sheshunoff's Opinion Letter which sets forth, among
other things, assumptions made, procedures followed, matters considered, and
limitations on the review undertaken, is attached as Annex C to this Prospectus
Supplement/Proxy Statement. First Corporation Shareholders are urged to read
Sheshunoff's Opinion Letter carefully and in its entirety. Sheshunoff's Opinion
Letter is addressed to the First Corporation Board, and does not constitute a
recommendation to any First Corporation Shareholder as to how such shareholder
should vote at the First Corporation Special Meeting.

         In connection with its Opinion Letter, Sheshunoff:

         1.       Reviewed the Merger Agreement;

         2.       Reviewed certain publicly available financial statements and
                  regulatory information concerning BancorpSouth and The First
                  Corporation, respectively;

         3.       Reviewed certain internal financial statements and other
                  financial and operating data of The First Corporation provided
                  to Sheshunoff by The First Corporation's management;

         4.       Reviewed the reported market prices and trading activity for
                  BancorpSouth Common Stock;

         5.       Discussed the past and current operations, financial
                  condition, and future prospects of The First Corporation with
                  its executive management;

         6.       Compared The First Corporation and BancorpSouth from a
                  financial point of view with certain other banking companies
                  that Sheshunoff deemed to be relevant;




                                       36

<PAGE>   40


         7.       Compared the financial performance of BancorpSouth and the
                  market prices and trading activity of BancorpSouth Common
                  Stock with that of certain other indices of publicly traded
                  equity securities;

         8.       Reviewed the financial terms, to the extent publicly
                  available, of certain comparable merger transactions in the
                  Southeastern United States and in Alabama; and

         9.       Performed such other analyses and reviews as Sheshunoff deemed
                  appropriate.

         In connection with its review, Sheshunoff relied upon and assumed the
accuracy and completeness of all of the foregoing information provided to it or
made publicly available. Sheshunoff did not assume any responsibility for
independent verification of such information. With respect to internal
confidential financial projections provided by The First Corporation, Sheshunoff
assumed that such projections were reasonably prepared on the basis reflecting
the best currently available estimates and judgments of the future financial
performance of The First Corporation and did not independently verify the
validity of such assumptions. Sheshunoff did not make any independent evaluation
or appraisal of the assets or liabilities of The First Corporation, nor was
Sheshunoff furnished with any such appraisals. Sheshunoff did not examine any
individual loan files of The First Corporation. Sheshunoff is not an expert in
the evaluation of loan portfolios for the purposes of assessing the adequacy of
the allowance for losses with respect thereto and has assumed that such
allowance is, in the aggregate, adequate to cover such losses.

         With respect to BancorpSouth, Sheshunoff relied solely upon publicly
available data regarding BancorpSouth's financial condition and performance.
Sheshunoff did not meet with or discuss this publicly available information with
the management of BancorpSouth. Sheshunoff did not conduct any independent
evaluation or appraisal of the assets, liabilities or business prospects of
BancorpSouth, was not furnished with any evaluations or appraisals, and did not
review any individual credit files of BancorpSouth.

   
         Sheshunoff's Opinion Letter is necessarily based on economic, market
and other conditions as in effect on, and the information made available to
Sheshunoff as of November 18, 1998.
    

         In connection with rendering its Opinion Letter, Sheshunoff performed a
variety of financial analyses. The preparation of an opinion involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances
and, therefore, such an Opinion Letter is not readily susceptible to partial
analysis of summary description. Moreover, the evaluation of fairness, from a
financial point of view, of the consideration to be received by First
Corporation Shareholders is to some extent subjective, based on the experience
and judgment of Sheshunoff, and not merely the result of mathematical analysis
of financial data. Accordingly, notwithstanding the separate factors summarized
below, Sheshunoff believes that its analyses must be considered as a whole and
that selecting portions of its analyses and of the factors considered by it,
without considering all analyses and factors, could create an incomplete view of
the evaluation process underlying its opinion. The ranges of valuations
resulting from any particular analysis described below should not be taken to be
Sheshunoff's view of the actual value of The First Corporation.

         In performing its analyses, Sheshunoff made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters, many of which are beyond the control of The First Corporation. The
analyses performed by Sheshunoff are not necessarily indicative of actual values
or future results, which may be significantly more or less favorable than
suggested by such analyses, nor are they appraisals. In addition, Sheshunoff's
analyses should not be viewed as determinative of the opinions of the First
Corporation Board and management with respect to the value of The First
Corporation.

   
         The following is a summary of the analyses performed by Sheshunoff in
connection with its Opinion Letter dated as of October 30, 1998 and updated as
of November 19, 1998. The following discussion contains financial information 
    



                                       37

concerning The First Corporation and BancorpSouth as of September 30, 1998 and
market information as of November 18, 1998.

         ANALYSIS OF SELECTED TRANSACTIONS. Sheshunoff performed an analysis of
premiums paid in selected pending or recently completed acquisitions of banking
organizations in Alabama and in the Southeastern United States, with comparable
characteristics to the Merger. Two sets of comparable transactions were analyzed
to ensure a thorough comparison.

         The first set of comparable transactions (the "State Transactions")
consisted of a group of comparable transactions based upon the geographical
market area of Alabama for which pricing data was available. The State
Transactions specifically consisted of eight mergers and acquisitions of banks
located in Alabama with assets less than $250 million which sold for stock
between October 1, 1997 and November 18, 1998. The pricing multiples have been
adjusted to reflect the change in BancorpSouth's stock price from the date of
the transaction to the stock price as of October 29, 1998. The analysis yielded
multiples of the State Transactions' purchase price relative to:

         1.       Book value ranging from 2.10 times to 3.46 times with an
                  average of 2.62 times and a median of 2.53 times (compared
                  with the implied multiples in the Merger of 2.52 times the
                  September 30, 1998 book value for The First Corporation);

         2.       Last 12 months earnings ranging from 16.7 times to 30.4 times
                  with an average of 22.3 times and a median of 22.7 times
                  (compared with the implied multiples in the Merger of 31.5
                  times the last 12 months earnings as of September 30, 1998 for
                  The First Corporation);

         3.       Total assets ranging between 24.4% and 45.6% with an average
                  of 29.0% and a median of 26.6% (compared with the implied
                  multiples in the Merger of 28.1% of the September 30, 1998
                  total assets for The First Corporation); and

         4.       Total deposits ranging from 27.9% to 54.4% with an average of
                  33.9% and a median of 31.2% (compared with the implied
                  multiples in the Merger of 33.1% of deposits as of September
                  30, 1998 for The First Corporation).
    

   
         The second set of comparable transactions (the "Southeastern
Transactions") consisted of a narrowly defined group of comparable transactions
based upon the profitability, asset size and geographical market area of The
First Corporation for which pricing data is available. The Southeastern
Transactions specifically consisted of 77 mergers and acquisitions of banks in
the Southeastern United States with total assets less than $250 million and
which sold for stock between October 1, 1997 and November 18, 1998. The analysis
yielded multiples of the Southeastern Transactions' purchase price relative to:

         1.       Book value ranging from 1.28 times to 5.59 times with an
                  average of 2.99 times and a median of 2.93 times (compared
                  with the multiples implied in the Merger of 2.52 times
                  September 30, 1998 book value for The First Corporation);

         2.       Last 12 months earnings ranging from 12.4 times to 59.7 times
                  with an average of 24.8 times and a median of 22.7 times
                  (compared with the multiples implied in the Merger of 31.5
                  times last 12 months earnings as of September 30, 1998 for The
                  First Corporation);

         3.       Total assets ranging between 13.3% and 60.6% with an average
                  of 29.5% and a median of 28.2% (compared with the multiples
                  implied in the Merger of 28.1% of September 30, 1998 total
                  assets for The First Corporation); and

         4.       Total deposits ranging from 15.0% to 68.5% with an average of
                  34.5% and a median of 33.4% (compared with the multiples
                  implied in the Merger of 33.1% of deposits as of September 30,
                  1998 for The First Corporation).

         DISCOUNTED CASH FLOW ANALYSIS. Using discounted cash flow analysis,
Sheshunoff estimated the present value of the future after-tax cash flow streams
that The First Corporation could produce through the year 2003, under various
circumstances, assuming that it performed in accordance with the earnings/return
projections of management.

   
         Sheshunoff estimated the terminal value for The First Corporation at
the end of the period by applying multiples of earnings ranging from 10 times to
22 times and then discounting the cash flow streams, dividends paid to the
shareholders (assuming all earnings in excess of that required to maintain a
tangible equity to asset ratio of 7.0% are paid out in dividends) and terminal
value using discount rates ranging from 13.0% to 17.0% chosen to reflect
different assumptions regarding the required rates of return of The First
Corporation and the inherent risk surrounding the underlying projections. This
discounted cash flow analysis indicated a range of $83.24 per share to $158.02
per share based on 232,321 fully-diluted shares outstanding, compared to the
value of the Merger Consideration for The First Corporation of $173.22 per
share, based on the Merger Consideration of $40,241,887.

         Sheshunoff also performed a cash flow analysis using an estimated
terminal value for The First Corporation at the end of the period by applying
multiples of book value ranging from 1.20 times to 2.30 times and then
discounting the cash flow streams, dividends paid to the shareholders (assuming
all earnings in excess of that required to maintain a tangible equity to
tangible asset ratio of 7.0% are paid out in dividends) and terminal value using
discount rates ranging from 13.0% to 17.0% chosen to reflect different
assumptions regarding the required rates of return of The First Corporation and
the inherent risk surrounding the underlying projections. This discounted cash
flow analysis indicated a range of $68.38 per share to $108.87 per share based
on 232,321 fully-diluted shares outstanding, compared to the value of the Merger
Consideration for The First Corporation of $173.22 per share, based on the
Merger Consideration of $40,241,887.

         COMPARABLE COMPANY ANALYSIS. Sheshunoff compared selected stock market
results of BancorpSouth to the publicly available corresponding data of other
composites which Sheshunoff deemed to be relevant, including SNL Securities,
L.P.'s ("SNL") index of all publicly traded banks, the SNL index of banks with
assets between $1 billion and $5 billion and the S&P 500. Results from indexing
the SNL's index of all publicly traded banks, the SNL index of banks with assets
between $1 billion and $5 billion, the S&P 500 and BancorpSouth Common Stock
from December 1, 1996 to November 13, 1998 revealed that BancorpSouth's stock
price outperformed the price movements of the SNL index of all publicly traded
banks.
    

         No company or transaction used in the comparable company and comparable
transaction analyses is identical to The First Corporation, BancorpSouth or the
Merger. Accordingly, an analysis of the results of the foregoing necessarily
involves complex considerations and judgments concerning differences in
financial and operating characteristics of The First Corporation and
BancorpSouth, and other factors that could affect the public trading value of
the companies to which they are being compared. Mathematical analysis (such as
determining the average or median) is not in itself a meaningful method of using
comparable transaction data or comparable company data.

         Pursuant to an engagement letter between The First Corporation and
Sheshunoff, The First Corporation agreed to pay Sheshunoff a fee equal to 5.0%
of the consideration in excess of $29.5 million received by The First
Corporation as a result of the Merger. The First Corporation also agreed to
indemnify and hold harmless Sheshunoff and its officers and employees against
certain liabilities in connection with its services under the engagement letter,
except for liabilities resulting from the negligence of Sheshunoff.

REGULATORY APPROVAL

         Consummation of the Merger is conditioned on, among other things, the
receipt of approvals by governmental authorities required in connection with the
Merger ("Requisite Regulatory Approvals"), including approvals by the Federal
Deposit Insurance Corporation ("FDIC"), the 




                                       39

<PAGE>   43


Mississippi Department of Banking and Consumer Finance and the Alabama Banking
Department. The Board of Governors of the Federal Reserve System ("Federal
Reserve") has waived its notification filing requirements with respect to the
Merger.

   
         As a state non-member bank, BancorpSouth Bank must file an application
with the FDIC for approval of the Merger pursuant to Sections 18(c) and 18(d) of
the Federal Deposit Insurance Act. The FDIC may disapprove the application if it
finds that the Merger tends to create or result in a monopoly, substantially
lessen competition or would be in restraint of trade. BancorpSouth Bank filed
such application with the FDIC on September 28, 1998. Following approval of the
application by the FDIC, the United States Department of Justice would have
between 15 and 30 calendar days to submit any adverse comments with regard to
the Merger relating to competitive factors. Such approval was obtained from the
FDIC on November 9, 1998. Pursuant to the specific terms of the FDIC approval,
the waiting period will expire on November 24, 1998, 15 days after receipt of
such FDIC approval.
    

         BancorpSouth must file an application with the Mississippi Department
of Banking and Consumer Finance for approval of the Bank Merger. BancorpSouth
filed such application on September 28, 1998. Approval of the Bank Merger by the
Mississippi Department of Banking and Consumer Finance is expected to be
received following approval of the Merger Agreement by First Corporation
Shareholders.

         The First Corporation and BancorpSouth also must file an application
with the Alabama Banking Department for approval of the Merger. Such application
consists primarily of providing to the Alabama Banking Department a copy of the
application filed with the FDIC, and paying any applicable application fees.
Such application was provided to the Alabama Banking Department on September 28,
1998. Approval of the Merger by the Alabama Banking Department is expected to be
received following approval of the Merger Agreement by First Corporation
Shareholders.

ACCOUNTING TREATMENT

         It is intended that the Merger will be accounted for as a pooling of
interests under generally accepted accounting principles ("GAAP"). The Merger is
conditioned upon BancorpSouth being satisfied that the Merger will qualify for
pooling of interests accounting treatment. In addition, BancorpSouth can
terminate the Merger Agreement if it is advised in writing by its independent
certified public accountants that the Merger does not qualify for pooling of
interests accounting treatment. The unaudited pro forma financial information
included in this Prospectus Supplement/Proxy Statement reflects the Merger using
the pooling of interests method of accounting. See "SUMMARY -- Comparative
Unaudited Per Share Data" and "SELECTED FINANCIAL DATA."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of the material anticipated U.S. federal
income tax consequences of the Merger to First Corporation Shareholders who hold
First Corporation Common Stock as a capital asset. The summary is based on the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations
thereunder, and administrative rulings and court decisions in effect as of the
date hereof, all of which are subject to change at any time, possibly with
retroactive effect. This summary is not a complete description of all of the
consequences of the Merger and, in particular, may not address U.S. federal
income tax considerations applicable to shareholders subject to special
treatment under U.S. federal income tax law. Examples of such shareholders
receiving special tax treatment are non-U.S. persons, financial institutions,
dealers in securities, insurance companies, tax-exempt entities, holders who
acquired First Corporation Common Stock pursuant to the exercise of an employee
stock option or right or otherwise as compensation, and holders who hold First
Corporation Common Stock as part of a hedge, straddle or conversion transaction.
In addition, no information is provided herein with respect to the tax
consequences of the Merger under applicable foreign, state or local laws. FIRST
CORPORATION SHAREHOLDERS ARE URGED TO CONSULT WITH THEIR TAX ADVISORS REGARDING
THE TAX CONSEQUENCES OF THE MERGER TO THEM, INCLUDING THE EFFECTS OF U.S.

FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND OF POTENTIAL CHANGES TO
APPLICABLE TAX LAW.

         BancorpSouth has received an opinion of Waller Lansden Dortch & Davis,
A Professional Limited Liability Company, special counsel to BancorpSouth, dated
November 2, 1998, addressing the U.S. federal income tax consequences of the
Merger described below. Such opinion has been rendered on the basis of facts,
representations and assumptions set forth or referred to in such opinion which
are consistent with the expected state of facts existing at the Effective Time.
In rendering this opinion, such counsel has required and relied upon
representations and covenants, including those contained in certificates of
officers of The First Corporation and BancorpSouth. The opinion is to the effect
that, for U.S. federal income tax purposes:

         1.       The Merger will be treated as a reorganization within the 
                  meaning of Section 368(a) of the Code;

         2.       No gain or loss will be recognized by BancorpSouth or The 
                  First Corporation as a result of the Merger;

         3.       No gain or loss will be recognized by First Corporation
                  Shareholders who exchange all of their respective common stock
                  solely for BancorpSouth Common Stock pursuant to the Merger
                  (except with respect to cash received in lieu of a fractional
                  share interest in BancorpSouth Common Stock); and

         4.       The aggregate tax basis of the BancorpSouth Common Stock
                  received by First Corporation Shareholders who exchange all of
                  their respective shares of First Corporation Common Stock
                  solely for BancorpSouth Common Stock pursuant to the Merger
                  will be the same as the aggregate tax basis of First
                  Corporation Common Stock surrendered in exchange therefor
                  (reduced by any amount allocable to a fractional share
                  interest for which cash is received).

         The First Corporation's obligation to consummate the Merger is
conditioned upon the receipt of an opinion of Jenkens & Gilchrist, A
Professional Corporation, and BancorpSouth's obligation to consummate the Merger
is conditioned upon the receipt of an opinion of Waller Lansden Dortch & Davis,
A Professional Limited Liability Company. Each of the opinions, to be dated the
date on which the Merger is completed, are to address the same U.S. federal
income tax consequences discussed in the immediately preceding paragraph and as
further described under the caption "THE MERGER AGREEMENT -- Conditions to the
Merger." None of the tax opinions to be delivered to the parties in connection
with the Merger are binding on the Internal Revenue Service (the "IRS") or the
courts. The parties do not intend to request a ruling from the IRS with respect
to the Merger. Accordingly, there can be no assurance that the IRS will not
challenge the conclusions reflected in such opinions or that a court will not
sustain such challenge.

         Generally, cash received by a First Corporation Shareholder in lieu of
a fractional share interest in BancorpSouth Common Stock will be treated as
received in redemption of such fractional share interest, and such First
Corporation Shareholder should generally recognize capital gain or loss for
federal income tax purposes measured by the difference between the amount of
cash received and the portion of the tax basis of the share of First Corporation
Common Stock treated as redeemed. Such gain or loss should be a long-term
capital gain or loss if the holding period for shares of First Corporation
Common Stock is greater than one year at the Effective Time. Generally, in the
case of individual shareholders, such capital gain will be taxed at a maximum
rate of 20% (10%, if the gain would be taxed at 15% if it were treated as
ordinary income) if such shareholder's holding period is more than one year. The
holding period of a share of BancorpSouth Common Stock received in the Merger
(including a fractional share interest deemed received and redeemed as described
above) will include the holder's holding period in First Corporation Common
Stock surrendered in exchange for BancorpSouth Common Stock.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain members of management of The First Corporation and the First
Corporation Board may be deemed to have certain interests in the Merger that are
in addition to their interests as shareholders generally. The First Corporation
Board was aware of these interests and considered them, among other matters, in
approving the Merger Agreement and the transactions contemplated thereby.

         In particular, Mr. William C. Kent, who is President of The First
Corporation and First National Bank, will become community bank president of the
branch locations of BancorpSouth Bank in the Opelika, Alabama area after the
Merger. Mr. Kent has entered into an employment agreement with BancorpSouth Bank
that is effective upon completion of the Merger. The employment agreement
provides for a term of two years, which may be renewed for additional one year
terms. The employment agreement also provides that Mr. Kent will receive an
annual salary of $118,368 and will be eligible for a discretionary bonus. In his
employment agreement, Mr. Kent has agreed that he will not compete with
BancorpSouth Bank within a specified area.

         Directors and executive officers of The First Corporation will be
issued shares of BancorpSouth Common Stock in the Merger on the same basis as
other First Corporation Shareholders. The following chart shows the number of
shares of BancorpSouth Common Stock that may be issued to directors and
executive officers of The First Corporation in the Merger:

             Beneficial ownership by executive
             officers and directors as of
             ___________, 1998(1)..................             55,885.41

             Shares of BancorpSouth Common Stock to 
             be received at the Effective Time 
             (based on such beneficial ownership):

                  Minimum..........................               430,557

                  Maximum..........................               582,521

             -------------------------
             (1)   Does not include 3,200 shares of common stock of The First 
                   Corporation subject to stock options exercisable on 
                   December 13, 1998. Includes 1,360.41 shares of common
                   stock of The First Corporation held by such persons as 
                   trustees of the First Corporation ESOP and which shares have
                   not been allocated to the participants in such plan.
                   Pursuant to the terms of this plan, the trustees may vote 
                   such unallocated shares in their discretion.

COMPARISON OF RIGHTS OF SHAREHOLDERS

         At the Effective Time, First Corporation Shareholders will
automatically become BancorpSouth shareholders (except for those shareholders
who exercise Dissenters' Rights). BancorpSouth is a Mississippi corporation
governed by provisions of the MBCA, the amended and restated articles of
incorporation of BancorpSouth (the "BancorpSouth Articles") and the bylaws of
BancorpSouth (the "BancorpSouth Bylaws"). The First Corporation is an Alabama
corporation governed by provisions of the ABCA, the articles of incorporation of
The First Corporation (the "First Corporation Articles") and the bylaws of The
First Corporation (the "First Corporation Bylaws"). See "COMPARISON OF RIGHTS OF
SHAREHOLDERS."

RESTRICTIONS ON RESALES BY AFFILIATES

         The shares of BancorpSouth Common Stock issuable to First Corporation
Shareholders upon consummation of the Merger have been registered under the
Securities Act of 1933 (the "Securities Act"). Such securities may be traded
freely without restriction by those shareholders who are not 



                                       42

<PAGE>   46


deemed to be "affiliates" of The First Corporation or BancorpSouth, as that term
is defined in the rules promulgated under the Securities Act.

         Shares of BancorpSouth Common Stock received by those First Corporation
Shareholders who are deemed to be affiliates of The First Corporation at the
time of First Corporation Special Meeting may be resold without registration
under the Securities Act only as permitted by Rule 145 under the Securities Act
or as otherwise permitted thereunder. Securities and Exchange Commission (the
"SEC") guidelines regarding qualifying for the pooling of interests method of
accounting also limit sales of shares of the acquiring and acquired company by
affiliates of either company in a business combination. SEC guidelines also
indicate that the pooling of interests method of accounting generally will not
be challenged on the basis of sales by affiliates of the acquiring or acquired
company if such affiliates do not dispose of any of the shares of the
corporation they own, or shares of a corporation they receive in connection with
a merger, during the period beginning 30 days before the merger is consummated
and ending when financial results covering at least 30 days of post-merger
operations of the combined companies have been published.

         Each of the parties has agreed in the Merger Agreement to use its
reasonable best efforts to cause each person who is an affiliate (for purposes
of Rule 145 under the Securities Act and for purposes of qualifying the Merger
for pooling of interests accounting treatment) of such party to deliver to the
other party a written agreement intended to ensure compliance with the
Securities Act (in the case of The First Corporation affiliates) and to preserve
the ability of the Merger to be accounted for as a pooling of interests.

         BancorpSouth has agreed in the Merger Agreement to use its best efforts
to publish financial results covering at least 30 days of post-Merger combined
operations, as contemplated by Accounting Series Release No. 135 issued by the
SEC, as soon as practical after such financial results are available.

                              THE MERGER AGREEMENT


         The following summary of certain terms and provisions of the Merger
Agreement is qualified in its entirety by reference to the Merger Agreement,
which is incorporated into this document by reference and, with the exception of
certain exhibits and schedules thereto, is attached as Annex A to this
Prospectus Supplement/Proxy Statement.

EXCHANGE OF CERTIFICATES

         At or prior to the Effective Time, BancorpSouth will deposit, or will
cause to be deposited, with the Exchange Agent, certificates representing the
shares of BancorpSouth Common Stock (collectively, "BancorpSouth Certificates")
and cash to be paid in lieu of fractional shares to which a holder of
certificates formerly representing First Corporation Common Stock ("First
Corporation Certificates") would otherwise be entitled based on the applicable
exchange ratio (such cash and BancorpSouth Certificates, together with any
dividends or distributions with respect thereto, the "Exchange Fund").

         As soon as practicable, but in no event more than three business days
after the date on which the Effective Time occurs (the "Effective Date"), the
Exchange Agent will mail to each holder of record of a First Corporation
Certificate a letter of transmittal for use in exchanging such shareholder's
First Corporation Certificates for the Merger Consideration. Upon surrender of a
First Corporation Certificate for exchange and cancellation to the Exchange
Agent, together with a duly executed letter of transmittal, the holder of a
First Corporation Certificate will be entitled to receive in exchange for such
First Corporation Certificate a BancorpSouth Certificate representing the number
of whole shares of BancorpSouth Common Stock to which such holder has become
entitled pursuant to the Merger Agreement. The holder of the First Corporation
Certificate may also receive a check in the amount of cash in lieu of fractional
shares, if any, of BancorpSouth Common Stock to which such holder has become
entitled pursuant to the Merger Agreement. First Corporation Certificates so
surrendered will immediately be canceled. No interest will be paid or accrued on
any cash to be paid upon such surrender, whether in lieu of fractional shares of
BancorpSouth Common Stock or with respect to unpaid dividends or distributions
thereon.


         FIRST CORPORATION SHAREHOLDERS SHOULD NOT SEND IN THEIR STOCK
CERTIFICATES UNTIL THEY RECEIVE THE TRANSMITTAL MATERIALS FROM THE EXCHANGE
AGENT.

         No fractional shares of BancorpSouth Common Stock, and no BancorpSouth
Certificates or scrip representing such fractional shares, will be issued in the
Merger. Also, no dividend or distribution will be payable on or with respect
thereto, nor will any such fractional share entitle the holder thereof to vote
or to any other rights of a BancorpSouth Shareholder. Instead, BancorpSouth will
pay to each First Corporation Shareholder who would otherwise be entitled to a
fractional share of BancorpSouth Common Stock (after taking into account all
First Corporation Certificates delivered by such shareholder) an amount in cash
to be paid in lieu of fractional shares (without interest) determined by
multiplying such fraction by the Average Closing Price of BancorpSouth Common
Stock.

         Any part of the Exchange Fund that remains unclaimed by First
Corporation Shareholders for 12 months after the Effective Time will be paid to
BancorpSouth. After such time First Corporation Shareholders may look only to
BancorpSouth for payment of the Merger Consideration and unpaid dividends and
distributions, if any, on First Corporation Common Stock deliverable in respect
of each share of First Corporation Common Stock held by such shareholder, in
each case, without interest thereon. None of The First Corporation, BancorpSouth
or the Exchange Agent, or any other person, will be liable to any former First
Corporation Shareholder for any amounts properly delivered to a public official
pursuant to applicable abandoned property, escheat or similar laws.




                                       44

<PAGE>   48



         If any First Corporation Certificate is lost, stolen or destroyed,
BancorpSouth can require, at its discretion, the making of an affidavit of that
fact by the person claiming the same and/or the posting of a bond by such person
in an amount that BancorpSouth or the Exchange Agent may direct as indemnity
against any claim that may be made against it with respect to such First
Corporation Certificate. Upon making such affidavit and/or posting such bond,
the Exchange Agent will issue in exchange for such First Corporation Certificate
the shares of BancorpSouth Common Stock and cash in lieu of fractional shares
deliverable in respect thereof.

         No dividends or other distributions with respect to BancorpSouth Common
Stock declared after the Effective Time and payable to BancorpSouth Shareholders
of record will be paid to the holder of any unsurrendered First Corporation
Certificate until the holder thereof surrenders such First Corporation
Certificate in accordance with the Merger Agreement. After the proper surrender
of a First Corporation Certificate, the record holder of the certificate will be
entitled to receive any such dividends or other distributions, without any
interest thereon, which had become payable with respect to shares of
BancorpSouth Stock represented by such First Corporation Certificate upon
completion of the Merger.

CONDITIONS TO THE MERGER

        The obligations of The First Corporation and BancorpSouth to complete
the Merger are subject to the satisfaction (or waiver, where legally allowed),
at or prior to the Effective Time, of a number of conditions, which are set
forth in the Merger Agreement. These conditions include:

         1.       Approval of the Merger Agreement by First Corporation 
                  Shareholders;

         2.       Receipt of the Requisite Regulatory Approvals;

         3.       The absence of any legal prohibition to completion of the 
                  Merger; and

         4.       The accuracy of the parties' representations and performance
                  of the parties' obligations under the Merger Agreement.

         In addition, the obligation of each party to consummate the Merger is
conditioned upon receipt of an opinion from their respective legal counsel to
the effect that the Merger will be treated as a reorganization within the
meaning of Section 368(a) of the Code and that, accordingly, for federal income
tax purposes:

         1.       No gain or loss will be recognized by BancorpSouth or The 
                  First Corporation as a result of the Merger;

         2.       No gain or loss will be recognized by First Corporation
                  Shareholders who exchange all of their respective shares of
                  First Corporation Common Stock solely for BancorpSouth Common
                  Stock pursuant to the Merger (except with respect to cash
                  received in lieu of a fractional share interest in
                  BancorpSouth Common Stock); and

         3.       The aggregate tax basis of the BancorpSouth Common Stock
                  received by First Corporation Shareholders who exchange all of
                  their respective shares of First Corporation Common Stock
                  solely for BancorpSouth Common Stock pursuant to the Merger
                  will be the same as the aggregate tax basis of First
                  Corporation Common Stock surrendered in exchange therefor
                  (reduced by any amount allocable to a fractional share
                  interest for which cash is received).

         The obligation of BancorpSouth to complete the Merger is also
conditioned upon:

         1.       Mr. William C. Kent, the President of The First Corporation, 
                  entering into an employment agreement with BancorpSouth Bank; 
                  and



                                       45

<PAGE>   49

         2.       BancorpSouth being satisfied the Merger may be accounted for 
                  using the pooling of interests method of accounting.

         Further, the obligation of The First Corporation to complete the Merger
is conditioned upon receipt by The First Corporation of an opinion from Alex
Sheshunoff & Co. Investment Banking to the effect that as of the date of the
opinion and based upon and subject to the matters set forth in the opinion, the
Merger is fair to First Corporation Shareholders from a financial point of view.
See "THE MERGER -- Fairness Opinion."

         The parties cannot guarantee that the Requisite Regulatory Approvals
will be obtained or that all of the other conditions precedent to the Merger
will be satisfied or, where legally permitted, waived by the party permitted to
do so.

TERMINATION OF THE MERGER AGREEMENT

         The Agreement may be terminated at any time prior to the Effective
Time, whether before or after approval of the Merger by First Corporation
Shareholders, as set forth in the Merger Agreement, including by mutual consent
of BancorpSouth and The First Corporation. In addition, the Merger Agreement may
be terminated by either party if:

         1.       A governmental entity issues a final order prohibiting the 
                  Merger or (subject to a 60 day waiting period) rejects an 
                  application for a Requisite Regulatory Approval;

         2.       The Merger is not consummated on or before June 30, 1999;

         3.       First Corporation Shareholders fail to approve the Merger; or

         4.       The other party materially breaches its representations or
                  covenants set forth in the Merger Agreement and fails to cure
                  that breach within the prescribed time limit.

         In addition, BancorpSouth may terminate the Merger Agreement if the
First Corporation Board has withdrawn, modified or changed in a manner adverse
to BancorpSouth its approval of the Merger, or its recommendation to First
Corporation Shareholders that such shareholders approve the Merger Agreement and
the Merger. BancorpSouth may also terminate the Merger Agreement if
BancorpSouth's independent certified public accountants advise BancorpSouth and
The First Corporation in writing that the Merger does not qualify for use of the
pooling of interests method of accounting.

         In the event that, without giving effect to the minimum and maximum
exchange ratio limitations, the exchange ratio computed in accordance with the
formula in the Merger Agreement exceeds 11.8132, The First Corporation may, at
its option and without penalty, terminate the Merger Agreement by giving prior
written notice to BancorpSouth, unless within 24 hours after such notice is
given, BancorpSouth agrees to increase the maximum exchange ratio of 10.4235 to
an amount proposed by The First Corporation that is not greater than the
computed exchange ratio. This would occur if the Average Closing Price of
BancorpSouth Common Stock was more than about $24.6643. If, however, the
computed exchange ratio is less than 7.0879, BancorpSouth may, at its option and
without penalty, terminate the Merger Agreement by giving prior written notice
to The First Corporation, unless within 24 hours after such notice is given, The
First Corporation agrees to lower the minimum exchange ratio of 7.7043 to an
amount proposed by BancorpSouth that is not less than the computed exchange
ratio. This would occur if the Average Closing Price of BancorpSouth Common
Stock was less than about $14.7985.

         The computed exchange ratio amount below which BancorpSouth can elect
to terminate the Merger Agreement, 7.0879, is less than the minimum exchange
ratio of 7.7043. Therefore, if the computed exchange ratio is less than 7.7043
but not less than 7.0879, the applicable exchange ratio would be limited to the
minimum exchange ratio of 7.7043 and BancorpSouth would not have the 




                                       46

right to terminate the Merger Agreement as a result. Similarly, the computed
exchange ratio amount above which The First Corporation can elect to terminate
the Merger Agreement, 11.8132, is more than the maximum exchange ratio of
10.4235. Therefore, if the computed exchange ratio is more than 10.4235 but not
more than 11.8132, the applicable exchange ratio would be limited to the maximum
exchange ratio of 10.4235 and The First Corporation would not have the right to
terminate the Merger Agreement as a result. If the Average Closing Price of
BancorpSouth Common Stock is viewed as an implied value, this could result in
First Corporation Shareholders receiving shares of BancorpSouth Common Stock
with an implied value of less than $174.8178 in exchange for each share of First
Corporation Common Stock.

         In the event of termination of the Merger Agreement pursuant to its
terms, the Merger Agreement will become void and have no effect, except with
respect to the parties' obligations regarding confidential information and
expenses as set forth in the Merger Agreement. Termination also will not relieve
or release a breaching party from liability or damages for its willful breach of
the Merger Agreement.

CONDUCT OF BUSINESS PRIOR TO THE MERGER AND OTHER COVENANTS

         In the Merger Agreement, each of the parties agreed that, prior to the
Effective Time and except as expressly contemplated or permitted by the Merger
Agreement or the Stock Option Agreement or with the prior written consent of the
other party, such party and its subsidiaries will carry on their businesses in
the ordinary course consistent with past practice. Each of the parties also
agreed to refrain from engaging in, or permitting its subsidiaries to engage in,
certain activities which are described in the Merger Agreement.

         The First Corporation agreed to refrain from:

         1.       Declaring or paying any dividends on, or making other
                  distributions in respect of any of its capital stock during
                  any period (except that The First Corporation may declare and
                  pay a single dividend immediately prior to the Effective Time
                  of $2.25 per share for The First Corporation's 1998 fiscal
                  year);

         2.       Issuing or acquiring its capital stock;

         3.       Issuing any options or other securities convertible into or
                  exchangeable for its capital stock;

         4.       Amending its articles of incorporation or bylaws;

         5.       Making any capital expenditure in excess of $100,000;

         6.       Engaging in a material acquisition of another business;

         7.       Adopting or amending any employee benefit plan or compensation
                  arrangement;

         8.       Entering into any loans in an original principal amount in 
                  excess of $2,000,000;

         9.       Incurring any indebtedness other than in the ordinary course 
                  of business consistent with past practice;

         10.      Disposing of any material assets other than in the ordinary 
                  course of business consistent with past practice; or

         11.      Entering into, renewing, amending or terminating any material
                  contract.



                                       47

<PAGE>   51



         In addition, The First Corporation agreed that, prior to the Effective
Time, it will not authorize or permit any of its officers, directors, employees
or agents to, directly or indirectly, solicit, initiate, facilitate, encourage
or participate in any inquiries, proposals, discussions or negotiations relating
to a tender or exchange offer, merger, consolidation or other business
combination involving The First Corporation or the acquisition of a substantial
portion of its capital stock or assets (a "Takeover Proposal"). The First
Corporation agreed to immediately cease and terminate any existing activities,
discussions or negotiations previously conducted with any parties other than
BancorpSouth with respect to any Takeover Proposal, and to notify BancorpSouth
immediately if it receives any Takeover Proposal, inquiry or request for
information. The First Corporation also agreed to promptly inform BancorpSouth
in writing of all of the relevant details with respect to any Takeover Proposal
or request for information, including the material terms and conditions and the
identity of the person or group making such request or proposal. Additionally,
The First Corporation agreed to keep BancorpSouth fully informed of the status
and details (including amendments or proposed amendments) of any such request or
Takeover Proposal.

         The First Corporation further agreed that it would not provide third
parties with any nonpublic information relating to any such Takeover Proposal.
It may, however, communicate information about any such Takeover Proposal to its
shareholders if, in the judgment of the First Corporation Board, such
communication is required under applicable law. In addition, The First
Corporation may, and may authorize and permit its officers, directors, employees
or agents to, provide or cause to be provided such information and participate
in such discussions or negotiations if the First Corporation Board has
determined that the failure to do so could cause the members of the First
Corporation Board to breach their fiduciary duties under applicable laws.

         The Merger Agreement also contains certain other agreements relating to
the conduct of the parties prior to the Effective Time, including, among other
things, those requiring each party:

         1.       To apply for and obtain all consents and approvals required to
                  consummate the Merger;

         2.       Except for privileged or confidential information, to afford
                  to the other party and its representatives access during
                  normal business hours to all of such party's information
                  concerning its business, properties and personnel as such
                  other party may reasonably request;

         3.       To cause each director, executive officer and other person who
                  is an "affiliate" of such party for purposes of Rule 145 under
                  the Securities Act and for purposes of qualifying the Merger
                  for pooling of interests accounting treatment, to deliver to
                  the other party to the Merger a written agreement intended to
                  ensure compliance with the Securities Act (in the case of The
                  First Corporation affiliates) and to preserve the ability of
                  the Merger to be accounted for as a pooling of interests; and

         4.       To take all actions required to comply with any legal 
                  requirements to consummate the Merger.

         The First Corporation also agreed to call and hold a special
shareholders meeting and, through the First Corporation Board, to recommend for
approval to its shareholders the Merger Agreement and the Merger.

         BancorpSouth also agreed that employees of The First Corporation and
First National Bank ("First Corporation Employees") will be eligible to
participate in BancorpSouth's employee benefit plans in a manner comparable to
that of similarly situated employees of BancorpSouth or BancorpSouth Bank. Prior
service with The First Corporation will be treated as service with BancorpSouth
for all such purposes (other than for accrual of pension benefits and 401(k)
plan eligibility) and except to the extent that such treatment would result in a
duplication or increase in benefits. First Corporation Employees are to be given
credit for amounts paid under an employee 



                                       48

<PAGE>   52


benefit plan period for purposes of applying deductibles, co-payments and
out-of-pocket maximums as though such amounts had been paid in accordance with
the terms and conditions of BancorpSouth's employee benefit plan.

         At the Effective Time, BancorpSouth and its subsidiaries are to assume
and honor all employment, severance and other compensation agreements and
arrangements existing prior to August 12, 1998 between The First Corporation and
the First National Bank and any director, officer or employee thereof that were
disclosed to BancorpSouth. The parties also agreed to cooperate and take all
reasonable actions after the Effective Time to effect the merger of any employee
benefit plan of The First Corporation that is intended to be qualified under
Section 401(a) of the Code into BancorpSouth's appropriate tax-qualified
retirement plan so that the merger of such plan satisfies the requirements of
Section 414(l) of the Code. The First Corporation employee benefit plan will not
be merged into BancorpSouth's appropriate tax-qualified retirement plan if The
First Corporation plan is not fully funded under Section 412 of the Code and
Section 302 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") or if the merger of the plan would jeopardize the tax-qualified status
of a BancorpSouth plan.

         In addition, BancorpSouth agreed to provide indemnification to the
officers, directors and employees of The First Corporation to the full extent
permitted by law from and after the Effective Time and to provide, for a period
of three years after the Effective Time, directors' and officers' liability
insurance for the directors and officers of The First Corporation to the maximum
extent available at an annual premium not to exceed 125% of the amount expended
by The First Corporation as of the date of the Merger Agreement. BancorpSouth
also agreed to cause the shares of BancorpSouth Common Stock to be issued in the
Merger to be approved for listing on the New York Stock Exchange.

AMENDMENT OF THE MERGER AGREEMENT; WAIVER; EXPENSES

         Subject to compliance with applicable law, the Merger Agreement may be
amended by the parties thereto, by action taken or authorized by their
respective Boards of Directors, at any time before or after approval of the
matters presented in connection with the Merger by First Corporation
Shareholders. However, after any approval of the Merger Agreement by First
Corporation Shareholders, there may not be, without further approval of such
shareholders, any amendment of the Merger Agreement which reduces the amount or
changes the form of the Merger Consideration. The Merger Agreement may not be
amended except by an instrument in writing signed on behalf of BancorpSouth and
The First Corporation.

         Prior to the Effective Time, BancorpSouth and The First Corporation may
extend the time for the performance of any of the obligations or other acts of
the other party to the Merger Agreement, waive any inaccuracies in the
representations or warranties of the other party contained in the Merger
Agreement or waive compliance with any of the agreements or conditions of the
other party contained in the Merger Agreement.

         Each party to the Merger Agreement will bear all expenses incurred by
it in connection with the Merger Agreement and the Merger.

STOCK OPTION AGREEMENT

         Concurrently with the execution of the Merger Agreement, BancorpSouth
and The First Corporation executed and delivered the Stock Option Agreement.
Under the Stock Option Agreement, The First Corporation granted to BancorpSouth
an option (the "Option") to purchase from The First Corporation up to 47,822
shares of First Corporation Common Stock (the "Option Shares") at an exercise
price of $125 per share. This number of shares is subject to adjustment in
certain circumstances, but in no event is the number of shares to exceed 19.9%
of the shares of First Corporation Common Stock issued and outstanding
immediately prior to exercise of the Option. The First Corporation approved and
entered into the Stock Option Agreement as an inducement to 



                                       49

<PAGE>   53


BancorpSouth to enter into the Merger Agreement. The Stock Option Agreement is
included as Annex D to this Prospectus Supplement/Proxy Statement. This
description is qualified in its entirety by reference to the full text of such
agreement.

         The Stock Option Agreement is intended to increase the likelihood that
the Merger will be completed. Consequently, certain aspects of the Stock Option
Agreement may have the effect of discouraging persons who might now or at any
other time prior to the Effective Time be interested in acquiring all of or a
significant interest in The First Corporation from considering or proposing such
an acquisition. The acquisition of The First Corporation other than by
BancorpSouth could cause the Option to become exercisable. The existence of the
Option could significantly increase the cost to a potential acquirer of
acquiring The First Corporation compared to its cost had the Stock Option
Agreement and the Merger Agreement not been entered into. Such increased cost
might discourage a potential acquirer from considering or proposing an
acquisition or might result in a potential acquirer proposing to pay a lower per
share price to acquire The First Corporation than it might otherwise have
proposed to pay. The exercise or repurchase of the Option may prohibit any other
acquirer of The First Corporation from accounting for an acquisition thereof
using the pooling of interests accounting method for a period of two years.

         The number of shares of First Corporation Common Stock subject to the
Option will be increased or decreased, as appropriate, to the extent that
additional shares of First Corporation Common Stock are either (1) issued or
otherwise become outstanding after August 12, 1998 or (2) redeemed, repurchased,
retired or otherwise cease to be outstanding after August 12, 1998, such that,
after such issuance, the number of Option Shares will continue to equal 19.9% of
the shares of First Corporation Common Stock then issued and outstanding. In the
event of any change in, or distributions in respect of, the number of shares of
First Corporation Common Stock that would be prohibited by the Merger Agreement,
the type and number of Option Shares purchasable upon exercise of the Option,
and the option price, will also be adjusted in such a manner as will fully
preserve the economic benefits of the Option.

         The Stock Option Agreement provides that BancorpSouth may exercise the
Option, in whole or in part, subject to regulatory approval, if both an Initial
Triggering Event (as defined in Section 2(b) of the Stock Option Agreement) and
a Subsequent Triggering Event (as defined in Section 2(c) of the Stock Option
Agreement) have occurred prior to the occurrence of an Exercise Termination
Event (as defined in Section 2(a) of the Stock Option Agreement). BancorpSouth
may exercise the Option only if BancorpSouth has sent to The First Corporation
written notice of such exercise within 90 days following such Subsequent
Triggering Event (subject to extension as provided in the Stock Option
Agreement). The terms "Initial Triggering Event" and "Subsequent Triggering
Event" generally relate to attempts by one or more third parties to acquire a
significant interest in The First Corporation. Any exercise of the Option will
be deemed to occur on the date such notice of exercise is sent.

         As of the date of this Prospectus Supplement/Proxy Statement,
BancorpSouth is not aware that an Initial Triggering Event or Subsequent
Triggering Event has occurred.

         Immediately prior to the occurrence of a Repurchase Event (as defined
in Section 7(d) of the Stock Option Agreement), following a request of
BancorpSouth, delivered prior to an Exercise Termination Event (as defined in
Section 2(a) of the Stock Option Agreement), The First Corporation (or any
successor thereto) will repurchase the Option from BancorpSouth at a price (the
"Option Repurchase Price") equal to the amount by which the Market/Offer Price
(as defined in Section 7(a) of the Stock Option Agreement) exceeds the option
exercise price, multiplied by the number of shares for which the Option may then
be exercised. In addition, at the request of BancorpSouth from time to time,
delivered within 90 days of such occurrence (or such longer period as necessary
to obtain any required regulatory approvals or to avoid liability under Section
16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")),
The First Corporation will repurchase such number of the Option Shares from
BancorpSouth as BancorpSouth designates at a price (the "Option Share 



                                       50

<PAGE>   54


Repurchase Price") equal to the Market/Offer Price multiplied by the number of
Option Shares so designated.

         Within 90 days after the occurrence of a Subsequent Triggering Event
that occurs prior to an Exercise Termination Date (as defined in Section 2(a) of
the Stock Option Agreement), subject to extension as provided in the Stock
Option Agreement, BancorpSouth may request The First Corporation to prepare,
file and keep current with respect to the Option Shares, a registration
statement with the SEC. The First Corporation is required to use its reasonable
best efforts to cause such registration statement to become effective and then
to remain effective for 180 days or such shorter time as may be reasonably
necessary to effect such sales or other disposition of Option Shares.
BancorpSouth has the right to demand two such registrations.

         Neither BancorpSouth nor The First Corporation may assign any of its
rights and obligations under the Stock Option Agreement or the Option to any
other person without the express written consent of the other party. However, if
a Subsequent Triggering Event occurs prior to an Exercise Termination Event,
BancorpSouth, subject to the terms of the Stock Option Agreement, may assign, in
whole or in part, its rights and obligations thereunder, within 90 days (subject
to extension to obtain necessary regulatory approvals or to avoid liability
under Section 16(b) of the Exchange Act) of such Subsequent Triggering Event.
BancorpSouth may not assign its rights under the Option until the date 15 days
after the date on which the Board of Governors of the Federal Reserve System
("Federal Reserve") approves an application by BancorpSouth to acquire the
Option Shares except in:

         1.       A widely dispersed public distribution;

         2.       A private placement in which no one party acquires the right 
                  to purchase in excess of 2% of the voting shares of The First 
                  Corporation;

         3.       An assignment to a single party for the purpose of conducting 
                  a widely dispersed public distribution on BancorpSouth's
                  behalf; or

         4.       Any other manner approved by the Federal Reserve.

         Certain rights and obligations of The First Corporation under the Stock
Option Agreement are subject to receipt of required regulatory approvals. The
approval of the Federal Reserve is required for the acquisition by BancorpSouth
of more than 5% of the outstanding shares of First Corporation Common Stock.
Accordingly, BancorpSouth has included or will include in its applications with
the Federal Reserve a request for approval of the right of BancorpSouth to
exercise its rights under the Stock Option Agreement, including its right to
purchase more than 5% of the outstanding shares of First Corporation Common
Stock.

                              THE FIRST CORPORATION
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   
         This discussion presents an analysis of the consolidated financial
statements of The First Corporation and its subsidiary, First National Bank, at
September 30, 1998 and December 31, 1997 and 1996, and the consolidated results
of operations for the nine-month periods ended September 30, 1998 and September
30, 1997, and for the years ended December 31, 1997, 1996 and 1995. The
following discussion should be read in conjunction with the consolidated
financial statements of The First Corporation and its subsidiary and the related
Notes appearing elsewhere in this Prospectus Supplement/Proxy Statement. The
information is presented on a consolidated basis for The First Corporation and
its subsidiary, First National Bank.

RESULTS OF OPERATIONS FOR THE NINE MONTH PERIOD ENDED SEPTEMBER 30, 1998 AS
COMPARED TO THE NINE MONTH PERIOD ENDED SEPTEMBER 30, 1997

         Net income for the nine months ended September 30, 1998 was
approximately $1,009,000, or $4.34 per share, compared to $1,061,000, or $4.63
per share, for the nine months ended September 30, 1997. Net income decreased
4.9% in 1998, as compared to the comparable period in 1997.

         The most significant factors affecting net income for the periods
mentioned were increased expenses related to the opening of a new branch office
in Auburn, Alabama, upgrading computer systems, the installation and
implementation of check imaging technology and the anticipated merger with
BancorpSouth.

         Net income for the nine months ended September 30, 1998 resulted in an
annualized return on average assets of 0.93% compared to 1.02% in 1997. The
annualized return on average stockholders' equity was 8.86% in 1998, as compared
to 10.34% for the same period in 1997.
    


         NET INCOME

   
         Following is an analysis of the primary components of net income for
the nine-month periods ended September 30, 1998 and September 30, 1997.

         Net interest income is the principal source of The First Corporation's
income and represents the difference between interest and fees earned on loans,
securities, and other interest-earning assets, interest paid on interest-bearing
deposits and other borrowings. Net interest income is affected by changes in the
volume of interest-earning assets and interest-bearing liabilities as well as
the rates earned or paid thereon. For the purposes of this earnings analysis,
net interest income has been adjusted to a taxable equivalent basis (assuming a
tax rate of 34% in 1998 and 1997) for non-taxable investment securities included
in interest-earning assets. The amount of the tax-equivalent adjustment was
$202,000 and $166,000 for the nine months ended September 30, 1998 and 1997,
respectively.

         The following table details average balances of interest-earning assets
and interest-bearing liabilities, the taxable equivalent amount of interest
earned/paid thereon and the taxable equivalent yield/rate for the nine-month
periods ended September 30, 1998 and September 30, 1997.

</TABLE>
    

   
         Interest income on a tax equivalent basis increased only 3.5% to
approximately $8,215,000 for the nine months ended September 30, 1998, as
compared to $7,939,000 for the comparable period in 1997. The annualized net
yield on interest-earning assets rose slightly to 8.09% in 1998, compared to
8.06% in 1997. This increase was primarily attributable to an increase in total
average interest-earning assets and a greater percentage of the interest-earning
assets being in the higher yielding loans and non-taxable securities categories
for the period ended September 30, 1998 as compared to the period ended
September 30, 1997. Although the average annualized yield on average loans
declined to 9.07% for the nine months ended September 30, 1998 from 9.11% for
the nine months ended September 30, 1997, average loans increased by 10.8%
during the same period. Non-taxable securities increased 21.7%

during the nine month period ended September 30, 1998 as compared to the same
period in 1997. Interest-earning assets as a percentage of total average assets
decreased from 94.3% in 1997 to 93.8% in 1998.

         Interest expense increased to approximately $4,271,000 (a 3.7%
increase) for the nine months ended September 30, 1998, from approximately
$4,120,000 for the comparable 1997 period. The increase in interest expense from
1997 to 1998 was a result of an increase in the dollar amount of
interest-bearing liabilities and a small increase in the average rate being paid
on those liabilities. The annualized average rate paid on interest-bearing
liabilities rose from 4.83% for the nine months ended September 30, 1997 to
4.88% for the same period in 1998. Money market accounts represented 18.5% of
interest-bearing liabilities during the 1998 period as compared to 17.0% during
the same period ended 1997 and the annualized yields paid on money market
accounts during the nine months ended September 30, 1998 and 1997 were 4.16% and
3.99%, respectively.

         Net interest income on a tax equivalent basis for the nine months ended
September 30, 1998 increased slightly to $3,944,000 from $3,819,000 for the same
period in 1997. The annualized net interest margin remained unchanged at 3.88%
for the nine months ended September 30, 1998, as compared to the same period in
1997. There are many factors that affect the rates earned on assets and paid on
liabilities. Strong competition for loans and deposits in the markets served has
a major impact on the yields earned and the rates paid. Federal Reserve monetary
policies, the international monetary markets, as well as local competitive
pressures, all have a direct or indirect impact on interest rates and,
therefore, affect the net interest spread and net yields earned by The First
Corporation.
    


         ALLOWANCE AND PROVISION FOR LOAN LOSSES

   
         The provision for loan losses was $70,000 for the nine month period
ended September 30, 1998, as compared to $145,000 for the same period in 1997.
The following table summarizes information concerning the allowance for loan
losses for the nine month period ended September 30, 1998. The First Corporation
management's estimate of the allowance for loan losses and the provision for
loan losses is based on a review of remaining collateral and/or financial
condition of identified loans with characteristically more than a normal degree
of risk, historical loan loss percentages, changes in the nature and volume of
the loan portfolio, current economic conditions that may affect a borrower's
ability to pay, the lending experience of the loan staff and the relationship of
the allowance for loan losses to outstanding loans.

         Net charge-offs for the nine month period ended September 30, 1998
were $30,000, as compared to net charge-offs of $59,000 for the comparable
period in 1997. The First Corporation management believes the allowance for loan
losses as of September 30, 1998 is adequate to cover losses inherent in the loan
portfolio.

         NONINTEREST INCOME

   
         Noninterest income increased by 17.6%, or approximately $75,000, to
approximately $501,000 for the nine months ended September 30, 1998, as compared
to approximately $426,000 for the same period in 1997. The increase was
primarily a result of increased service charge income, other fee income and a
non-recurring fee of approximately $23,000 paid by a computer software vendor
for late delivery of their product.

         NONINTEREST EXPENSE

         Noninterest expense increased to $2,750,000 for the nine months ended
September 30, 1998, or 9.1% higher than for the nine months ended September 30,
1997. This increase of approximately $229,000, as compared to the same period in
1997, is primarily attributable to increased salary expenses, computer expenses,
and depreciation expense directly related to the increased staff, new banking
facility and equipment required to open and operate the new branch office in
Auburn, Alabama, which opened in July 1997. None of those expenses would have
occurred during the first six months of 1997 since the branch was not operating
during that time period. In addition, the equipment and software expenses
related to providing new check imaging technology contributed to the increase in
noninterest expenses. Customers began receiving check imaged statements during
the latter half of 1997.

         INCOME TAXES

   
         The provision for income taxes for the nine months ended September 30,
1998 and 1997 was $416,000 and $352,000, respectively. The First Corporation's
effective tax rate for the first nine months of 1998 increased to 29.2% from
24.9% for the same period in 1997. The effective tax rates can vary based on
increases and decreases in certain nontaxable income or nondeductible expenses.

FINANCIAL CONDITION FOR THE PERIOD ENDED SEPTEMBER 30, 1998 AS COMPARED TO THE
PERIOD ENDED SEPTEMBER 30, 1997


         LOANS

         Loans, net of unearned interest, increased $7.8 million, or 10.2%, to
$84.1 million as of September 30, 1998, as compared to September 30, 1997. The
allowance for loan losses was $1,193,000 and $1,172,000 as of September 30, 1998
and 1997, respectively. Allowance for loan losses represented 1.42% of total
loans as of September 30, 1998, as compared to 1.54% as of September 30, 1997.
The allowance for loan losses account is analyzed each quarter and, based on
that analysis, it is believed by management of The First Corporation that the
amount in the account is sufficient to cover inherit losses in the loan
portfolio. The most significant concentration of loans consisted of commercial,
agricultural and industrial loans in addition to real estate secured loans.
    


         SECURITIES

   
         The First Corporation's investment securities portfolio decreased
8.6%, or $4,207,000, to $44,524,000 as of September 30, 1998 from $48,731,000 at
September 30, 1997. The primary reason for the decrease was a decision by
management of The First Corporation to either use the funds generated by
maturing or called securities to fund loans or place them in overnight federal
funds sold to provide liquidity to fund future loan growth. In addition, the
yields on federal funds sold provided a positive and acceptable alternative when
compared to the available yields in the securities market. The First Corporation
maintains an investment strategy of seeking portfolio yields within acceptable
risk levels, as well as providing liquidity. Most of The First Corporation's
investment securities are classified as available for sale in an effort to
maintain maximum liquidity in the portfolio. Securities classified as available
for sale represent securities that The First Corporation intends to hold for an
indefinite period of time or that may be sold in response to changes in interest
rates, liquidity needs, prepayment risk and other similar factors.


         DEPOSITS

         Total deposits increased 2.6%, or $3,026,000, to $121,539,000 as of
September 30, 1998 from $118,513,000 as of September 30, 1997. Time deposits
increased $2.8 million, or 4.6%, to $65.4 million for the period ended September
30, 1998 from $62.6 million for the comparable period in 1997. NOW and money
market deposits increased $1.8 million, or 4.8%, to $38.9 million for the period
ended September 30, 1998 from $37.1 million for the comparable period in 1997.
Demand deposits were $12.0 million and $13.6 million at September 30, 1998 and
1997, respectively.

RESULTS OF OPERATIONS FOR THE FISCAL YEARS ENDED DECEMBER 31, 1997, 1996 AND
1995
    


         EARNINGS SUMMARY

         The First Corporation reported net income of approximately $1,330,000,
or $5.79 per share, for the year ended December 31, 1997, as compared to net
income of approximately $1,321,000, or $5.85 per share, and approximately
$831,000, or $3.70 per share, for the years ended December 31, 1996 and December
31, 1995, respectively. Net income was basically level in 1997 as compared to
1996; however, net income increased by approximately $490,000, or 59.0%, in 1996
as compared to 1995. The primary reasons for the increase in earnings in 1996 as
compared to 1995 was an increase in the net interest margin, security gains
taken to enhance overall yields in the securities portfolio and the stability of
rates paid on interest-bearing liabilities. On a tax equivalent basis



                                       58
<PAGE>   62

(assuming a tax rate of 34% in 1997, 1996, and 1995), the net interest margin
increased to 3.67% in 1996 as compared to 3.43% in 1995. The increase in the net
interest margin was a result of loan growth and increased yields in the
investment portfolio. With management emphasizing quality loan growth in 1996,
average loans increased by approximately $12,493,000, or 22.8%, in 1996, as
compared to 1995. Due to the loan growth, the provision for loan losses was
increased by $80,000, or 61.1% in 1996 as compared to 1995. Net security gains
of $198,000 were recognized in 1996 as compared to $69,000 for the same period
in 1995. The overall tax equivalent yield on the investment portfolio increased
to 6.79% in 1997 from approximately 6.57% and 6.31% in 1996 and 1995,
respectively. Although net income did not increase significantly in 1997 as
compared to 1996 ($9,000), income (before taxes and securities gains) increased
by approximately $284,000, or 19.5%, as compared to 1996. The increase in the
net operating income was attributable to continued loan growth, with average
loans increasing by approximately $8,547,000, or 12.7%, as compared to the same
period in 1996.

         Net income for the year ended December 31, 1997 resulted in an
annualized return on average assets of 0.94%, compared to 0.96% and 0.67% in
1996 and 1995, respectively. The annualized return on average stockholders'
equity was 9.51% in 1997, as compared to 10.43% in 1996 and 7.26% in 1995.


         NET INTEREST INCOME

         For the purposes of this earnings analysis, net interest income has
been adjusted to a taxable equivalent basis (assuming a tax rate of 34% ) for
certain investments included in interest-earning assets. The amount of the
tax-equivalent adjustment for the years ended December 31, 1997, December 31,
1996, and December 31, 1995 was $254,000, $228,000, and $265,000 respectively.

         Interest income increased approximately $498,000 to $10.6 million for
the year ended December 31, 1997 from $10.1 million for the comparable period in
1996. Interest income for the year ended December 31, 1996 increased
approximately $1,178,000 from $9.0 million for the comparable period in 1995.
These increases were primarily attributable to the increase in the average yield
on interest-earning assets from 7.64% in 1995 to 7.90% in 1996 and to 8.14% in
1997. In addition, interest-earning assets increased by 1.8% and 9.3% for the
year ended December 31, 1997 and 1996, respectively. Although the average yield
on loans remained level at approximately 9.14% during the 1995-1997 period,
average loans grew at an annualized rate of 12.7% in 1997 and 22.8% in 1996.
Average loans represented 58.0% of average interest-earning assets in 1997 as
compared to 52.4% and 46.7% in 1996 and 1995, respectively. In contrast, average
investment securities declined to 40.5% of average interest-earning assets in
1997, as compared to 46.1% and 51.8% in 1996 and 1995, respectively. Investment
yields increased from 6.31% in 1995 to 6.79% in 1997.

         Interest expense increased approximately $69,000, or 1.3%, to
approximately $5.50 million for the year ended December 31, 1997, from
approximately $5.43 million for the comparable 1996 period. Interest expense for
the year ended December 31, 1996 increased approximately $493,000 from $4.9
million for the comparable period in 1995. The slight fluctuations in interest
expense from 1995 through 1997 were attributable to increases and decreases in
the volume of interest-bearing liabilities. The average rate paid on
interest-bearing liabilities was 4.86%, 4.88% and 4.84% for the years ended
December 31, 1997, 1996 and 1995, respectively. Time deposits represented 55.6%
of average interest-bearing liabilities for the year ended December 31, 1997, as
compared to 56.3% and 57.6% for the years ended December 31, 1996 and 1995,
respectively. The yields paid on time deposits during the years ended December
31, 1997, 1996 and 1995 were 5.75%, 5.79% and 5.77%, respectively. Short-term
and long-term borrowings represented 5.28% of interest-bearing liabilities for
the year ended December 31, 1997, as compared to 4.74% and 2.99% for the years
ended December 31, 1996 and 1995, respectively. The yields paid on the
borrowings were 5.52%, 5.28% and 4.46% for the years ended December 31, 1997,
1996 and 1995, respectively.

         Net interest income on a tax equivalent basis increased 9.1% to $5.1
million in 1997 from $4.7 million in 1996 and 17.0% in 1996 from $4.0 million in
1995. The net interest margin between interest-earning assets and
interest-bearing liabilities increased to 3.93% for the year ended December 31,
1997 from 3.67% for the year ended December 31, 1996. The net interest margin in
1995 was 3.43%. There are many factors that affect the rates earned on assets
and paid on liabilities. Strong competition for loans and deposits in the
markets we serve has a major impact on the yields earned and the rates paid.
Federal Reserve monetary policies, the international monetary

markets, as well as local competitive pressures, all have a direct or indirect
impact on interest rates and, therefore, affect the net interest spread and net
yields earned by The First Corporation.

         ALLOWANCE AND PROVISION FOR LOAN LOSSES

         The provision for loan losses provides an allowance (the allowance for
loan losses) against which loan losses are charged as those losses become
evident. Management of The First Corporation evaluates the appropriate level of
the allowance for loan losses on a quarterly basis. The analysis takes into
consideration the results of an ongoing loan review process, the purpose of
which is to determine the level of credit risk within the portfolio and to
ensure proper adherence to underwriting and documentation standards. Additional
allowances are provided to those loans which appear to represent a greater than
normal exposure to risk. The quality of the loan portfolio and the adequacy of
the allowance for loan loss is verified by regulatory exams and by First
National Bank's on-going third party loan review. In addition, estimates are
made for potential losses on loans not specifically reviewed based on historical
loan loss experience and other factors and trends.

         The First Corporation's provision for loan losses was $195,000 in 1997,
$211,000 in 1996 and $131,000 in 1995. The larger provisions in 1996 and 1997
were made to increase the allowance for loan loss reserve to reflect the loan
growth and absorb the net loan losses experienced during those years. Net
charge-offs for the year ended December 31, 1997 totaled $128,000, an increase
of $139,000 from the net recovery of $11,000 for the year ended December 31,
1996. The net charge-offs for 1995 was $106,000. The First Corporation's
management considers the allowance for loan losses as of December 31, 1997 to be
adequate to cover losses inherent in the loan portfolio.

         NONINTEREST INCOME

         Noninterest income decreased by 20.02%, or approximately $147,000, to
approximately $587,000 for the year ended December 31, 1997, as compared to
approximately $734,000 for the same period in 1996. The decrease was a result of
a decrease in security gains from $198,000 in 1996 to $12,000 in 1997.
Noninterest income for the year ended December 31, 1995 was $540,000. Service

         NONINTEREST EXPENSE

         Noninterest expense was $3,519,000 in 1997, $176,000, or 5.26%, higher
than in 1996. Noninterest expense for the years ending December 31, 1996 and
1995 was $3,343,000 and $3,123,000, respectively. Noninterest expense as a
percentage of average assets was 2.53% in 1997, 2.46% in 1996, and 2.50% in
1995. Salaries and employee benefits expenses increased only $5,000, or 0.26%,
in 1997 and increased $237,000, or 13.85%, in 1996. Other expense (excluding
expenses of premises and fixed assets) was $1,023,000 in 1997, $940,000 in 1996
and $986,000 in 1995. Expenses of premises and fixed assets increased $88,000,
or 19.3%, to $543,000 for the year ended December 31, 1997 from $455,000 for the
comparable 1996 period. Expenses of premises and fixed assets for the year ended
December 31, 1995 were $426,000. The increase from 1996 to 1997 was directly
related to establishing and opening a branch office in Auburn, Alabama,
purchasing and installing computer equipment necessary for the additional
facility and to process check imaged statements.

         INCOME TAXES

         The provision for income taxes for the years ended December 31, 1997,
1996 and 1995 was $422,000, $334,000 and $209,000, respectively. The First
Corporation's effective tax rate for years ended December 31, 1997, 1996 and
1995 was 24.1%, 20.2% and 20.1%, respectively. The effective tax rates can vary
based on increases and decreases in certain nontaxable income or nondeductible
expenses. The lower tax rates in 1995 and 1996 can be directly attributed to the
smaller amount of taxable income generated by the company during those years and
the use of prior years accumulated alternative minimum tax credits.

FINANCIAL CONDITION FOR THE FISCAL YEARS ENDED DECEMBER 31, 1997 AND 1996

         LOANS

         Loans, net of unearned interest, increased $11.2 million, or 15.86%, to
$82.0 million as of December 31, 1997, from $70.8 million for the comparable
1996 period. Loans, net of unearned interest, were $60.5 million at December 31,
1995. The allowance for loan losses was $1,153,000 at year-end 1997, $1,086,000
at year-end 1996 and $846,000 at year-end 1995. The most significant
concentration of loans consisted of commercial, agricultural and industrial
loans in addition to real estate secured loans.

         SECURITIES

         The First Corporation's and its subsidiary's investment securities
portfolio (excluding Federal Reserve and Federal Home Loan Bank stock) decreased
13.1%, or $7,722,000, to $47,941,000 as of December 31, 1997 from $55,163,000 at
December 31, 1996. The primary reason for the decrease was a decision by
management to either use the funds generated by maturing or called securities to
fund loans or place them in overnight federal funds sold to provide liquidity to
fund future loan growth. In addition, the yields on federal funds sold provided
a positive and acceptable alternative when compared to the available yields in
the securities market. The First Corporation maintains an investment strategy of
seeking portfolio yields within acceptable risk levels, as well as providing
liquidity. All of The First Corporation's investment securities are classified
as available for sale in an effort to maintain maximum liquidity in the
portfolio. Securities classified as available for sale represent securities that
The First Corporation intends to hold for an indefinite period of time or that
may be sold in response to changes in interest rates, liquidity needs,
prepayment risk and other similar factors.

         LIQUIDITY

         The First Corporation and its subsidiary have a formal Asset and
Liability Management Policy which includes a liquidity management policy.
Management recognizes the importance of sound liquidity management to
depositors, creditors and regulators. The goal of the established policy is to
focus The First Corporation attention on the Asset/Liability management process
and, therefore, ensure it's ability to meet liquidity needs to fund asset
growth. The First Corporation must always maintain the ability to have readily
available funds sufficient to repay fully maturing liabilities and fund asset
growth. The First Corporation and its subsidiary's liquidity, represented by
cash and due from banks, is a result of its operating, investing, and financing
activities. To insure funds are available at all times, The First Corporation
and its subsidiary project on a monthly basis the funds required to meet
projected cash flow needs over the next 30 and 90 day periods. Liquidity
requirements can also be met through short-term borrowings or the disposition of
short-term assets

which are generally matched to correspond to the maturity of liabilities. In the
event of any unforeseen circumstances that may create temporary cash flow needs
beyond what has been projected, The First Corporation and First National Bank
have established a liquidity contingency funding plan to address those needs.

         The First Corporation and First National Bank are not subject to any
specific regulatory liquidity requirements imposed by regulatory authorities.
Management does not know of any cash flow trends or demands which are likely to
result in liquidity increasing or decreasing in any material manner and believes
the liquidity levels are adequate. The following is The First Corporation and
First National Bank's liquidity ratios for the periods indicated:

         CAPITAL

         The Office of the Comptroller of the Currency (the "OCC") and the
Federal Reserve have adopted capital guidelines governing the activities of
banks and bank holding companies. These guidelines require the maintenance of an
amount of capital based on risk-adjusted assets so that categories of assets
with potentially higher credit risk will require more capital backing than
assets with lower risk. In addition, bank and bank holding companies are
required to maintain capital to support, on a risk-adjusted basis, certain
off-balance sheet activities such as loan commitments.

         Minimum capital requirements for all banks are total capital of at
least 8% of risk-weighted assets, Tier I risk-based capital of at least 4% and a
leverage ratio of at least 3%. Each of The First Corporation and First National
Bank's capital levels at December 31, 1997 and 1996 exceeded the "well
capitalized" levels under the regulatory framework.

         The following table provides information regarding The First
Corporation and First National Bank's capital ratios:

         INTEREST SENSITIVITY

         The First Corporation monitors and manages the repricing and maturity
of its assets and liabilities through an asset/liability management committee
formed by the First Corporation Board. In order to diminish the potential
adverse impact that changes in interest rates could have on its net interest
income, the asset/liability management committee uses a traditional gap analysis
(as well as other analytical tools) which compares the repricings, maturities
and payments, as applicable, of The First Corporation's rate sensitive interest
earning assets ("RSA") to rate sensitive interest bearing liabilities ("RSL").
The asset/liability management committee uses the GAP analysis and the results
of an asset/liability management computer program to monitor changes in net
interest income due to projected and simulated changes in market interest rates.
The First Corporation's GAP target is to maintain a GAP-to-assets ratio of +/-
15% at the one year time interval. At December 31, 1997, the ratio was within
the target range at (3.83)%.

</TABLE>

         As of December 31, 1997, the cumulative GAP analysis indicated that The
First Corporation was liability sensitive in relation to changes in market
interest rates. This means that increases in market interest rates could have a
negative impact, and decreases in market interest rates could have a positive
impact, on net interest income if GAP adjustments are not made.

CENTURY DATE CHANGE (YEAR 2000)

         The century date change problem, commonly referred to as the Year 2000
problem, has the potential to affect any computer hardware or software system.
The basis of the problem hinges upon how computer systems store and utilize date
fields in their processing. Systems which store and maintain the year portion of
a numerical date as a two-digit number rather than a four-digit number



                                       69
<PAGE>   73

may incorrectly read the Year 2000 as the Year 1900. This is due to the year
being maintained as the last two digits of the year rather than as the complete
four digit number.

         The management of each of The First Corporation and First National Bank
have committed the funds and manpower necessary to ensure that there will be no
negative impact on the daily operations of the company due to the century date
change. Following the guidelines of the Federal Financial Institution
Examination Council (FFIEC) and the OCC, The First Corporation and First
National Bank have completed several major activities in preparation of the
century date change, including the following.

         1.       The First Corporation and First National Bank have undertaken
                  an extensive internal and external awareness campaign that
                  includes not only the initial awareness-raising efforts, but
                  emphasizes continuing, proactive and ongoing activities to
                  maintain heightened awareness of century date change
                  implementations in the future;

         2.       The institution's core system was purchased from a highly
                  regarded third party vendor, and testing of this system will
                  be performed in a user group environment during the fourth
                  quarter of 1998;

         3.       Contact and follow up with the computer system vendor is being
                  maintained to verify that all testing will be handled in
                  accordance with FFIEC guidelines;

         4.       An aggressive review has been undertaken of the customer base
                  in an attempt to identify those customers who might have their
                  business operations most affected by the century date change,
                  and members of management have actively engaged these
                  customers in discussions regarding century date change
                  remediation;

         5        Management at both the senior and Board of Directors level
                  understands the implications of the century date change and
                  has actively monitored the progress of century date change
                  readiness activities;

         6.       Senior managers of First National Bank participate in an EDP
                  Steering Committee which monitors and reports to the full
                  Board of Directors all century date change related efforts
                  being conducted by The First Corporation and First National
                  Bank; and

         7.       Testing is currently on-going, and due to the limited amount
                  of time remaining prior to the Year 2000, testing has been
                  prioritized based on the criticality of the system.

         The First Corporation has three categories of priority for testing.
These are:

                  "A" Priority Systems: These are mission critical systems that
         will be tested at all costs since they are rated as critical to the
         welfare of The First Corporation and First National Bank.

                  "B" Priority Systems: These are critical systems that must be
         tested; however, if they fail, or are not tested, the institution will
         continue to operate. These systems will be tested, but to a lesser
         degree than "A" Priority items.

                  "C" Priority Systems: These are systems that will not
         materially impact the institution if they are not fixed prior to
         December 31, 1999, and as a result, will not require testing prior to
         entering the Year 2000. Systems may fall into this category because
         they will no longer be used or the system is not mission-critical to
         The First Corporation and First National Bank and/or an alternative can
         be easily implemented or is readily available.



                                       70
<PAGE>   74

         The First Corporation plans to complete century date change testing in
a time frame consistent with that required by the FFIEC. The FFIEC requires that
testing be completed by the end of the first quarter of 1999. Management of The
First Corporation believes the plan in place is adequate to address the issue.
The final outcome of all testing and renovation efforts for The First
Corporation and First National Bank are not expected to have a material adverse
effect on operations.

                     INFORMATION ABOUT THE FIRST CORPORATION


GENERAL

         THE FIRST CORPORATION. The First Corporation was incorporated in 1988
under the laws of the State of Alabama to serve as the holding company for First
National Bank. The First Corporation is a bank holding company registered under
the Bank Holding Company Act of 1956, as amended (the "Bank Holding Company
Act"), and owns all of the issued and outstanding capital stock of First
National Bank.

of approximately $15.95 million.
    

         The First Corporation does not, as an entity, engage in separate
business activities of a material nature apart from the activities it performs
for First National Bank. The primary activities of The First Corporation are to
provide assistance in the management and coordination of First National Bank's
financial resources and to provide capital and public relations services for
First National Bank. First National Bank has a board of directors separate from
that of The First Corporation and operates under the day-to-day management of
its own officers. First National Bank formulates its own policies with respect
to banking and business matters.

         As a bank holding company, The First Corporation is subject to
regulation by the Federal Reserve in accordance with the requirements set forth
in the Bank Holding Company Act and by the rules and regulations promulgated
thereunder by the Federal Reserve. Certain of these rules and regulations
applicable to The First Corporation are summarized in this section below.

         The First Corporation's primary source of revenues is dividends
received from First National Bank.

         THE FIRST NATIONAL BANK OF OPELIKA. First National Bank is a national
banking association with its main office in Opelika, Alabama. The bank was
originally chartered in 1886 under the laws of the United States. As a national
banking association, First National Bank is subject to regulation by the OCC in
accordance with the requirements set forth in the National Bank Act and the
rules and regulations of the OCC thereunder. Certain of these rules and
regulations applicable to First National Bank are summarized in this section
below.

   
         First National Bank considers its primary market to be Lee County,
Alabama, which has a total population of approximately 97,000. The majority of
First National Bank's loan portfolio consists of real estate and commercial
loans, while consumer deposits comprise the majority of First National Bank's
deposit base. As of September 30, 1998, First National Bank had total assets of
approximately $143.4 million, total deposits of approximately $121.5 million,
total loans of approximately $84.1 million (net of unearned discount and
allowance for loan losses) and total shareholders' equity of approximately
$15.95 million.
    

         First National Bank operates from its main facility in Opelika, Alabama
and from two branches located in Opelika and Auburn, Alabama. Each of these
facilities is owned by First National Bank and, collectively, these facilities
are considered by management of First National Bank to be adequate for the
operations of the bank.

         First National Bank is a full-service commercial bank offering a wide
variety of traditional banking products and services to the communities it
serves, including depository services such as



                                       72
<PAGE>   76

checking accounts, savings accounts, certificates of deposit, individual
retirement accounts, commercial and retail loan products and mortgage products.
The bank also provides investment services through a third party marketer. First
National Bank has trust powers, but has elected not to provide any trust or
fiduciary services. First National Bank also offers direct deposit services,
wire transfer facilities, safe deposit boxes and ATM and debit cards (with
access to local, state and nationwide networks). Deposits of First National Bank
are insured by the FDIC.

EMPLOYEES

         The First Corporation is a bank holding company and primarily conducts
its operations through its subsidiary, First National Bank. The First
Corporation has no paid employees. Certain employees of First National Bank
conduct the business of The First Corporation, but are not specifically
compensated as employees of The First Corporation. As of June 30, 1998, First
National Bank had approximately 60 full-time equivalent employees, none of whom
is represented by a collective bargaining agreement. Management of First
National Bank considers its relations with such employees to be good.

SUPERVISION AND REGULATION

         THE FIRST CORPORATION. As a bank holding company under the Bank Holding
Company Act, The First Corporation is registered with and is subject to
regulation and supervision by the Federal Reserve. Among other things, The First
Corporation is required to furnish the Federal Reserve an annual report of its
operations at the end of each fiscal year and to furnish such additional
information as the Federal Reserve may require pursuant to the Bank Holding
Company Act. The Federal Reserve may also make inspections of The First
Corporation.

         The Bank Holding Company Act requires, subject to certain exceptions,
every bank holding company to obtain the prior approval of the Federal Reserve:

         1.    Before it may acquire direct or indirect ownership or control of
               any voting shares of any bank if, after such acquisition, such
               bank holding company will directly or indirectly own or control
               more than 5% of the voting shares of such bank;

         2.    Before it or any of its subsidiaries, other than a bank, may
               acquire all or substantially all of the assets of a bank; or

         3.    Before it may merge or consolidate with any other bank holding
               company.

         In addition, the Bank Holding Company Act prohibits (with specific
exceptions) The First Corporation from engaging in nonbanking activities or from
acquiring or retaining direct or indirect control of any company engaged in
nonbanking activities. The Federal Reserve, by regulation or order, may make
exceptions for activities determined to be so closely related to banking,
managing or controlling banks as to be a proper incident thereto. In determining
whether a particular activity is permissible, the Federal Reserve considers
whether the performance of such an activity can reasonably be expected to
produce benefits to the public, such as greater convenience, increased
competition or gains in efficiency that outweigh possible adverse effects.
Examples of possible adverse effects are undue concentration of resources,
decreased or unfair competition, conflicts of interest or unsound banking
practices. The Federal Reserve has determined that making, acquiring or
servicing loans, leasing personal property, providing certain investment or
financial advice, performing certain data processing services, acting as agent
or broker in selling credit life insurance and certain other types of insurance
in connection with credit transactions by the bank holding company and certain
limited insurance underwriting activities are permissible activities. The Bank
Holding Company Act does not place territorial limitations on permissible
bank-related activities of bank holding companies. However, despite prior
approval, the Federal Reserve has the power to order a bank holding company or
its subsidiaries to terminate any activity, or terminate its



                                       73
<PAGE>   77

ownership or control of any subsidiary, when it has reasonable cause to believe
that continuation of such activity, ownership or control constitutes a serious
risk to the financial safety, soundness or stability of any bank subsidiary of
that bank holding company.

         THE FIRST NATIONAL BANK OF OPELIKA. First National Bank is subject to
various requirements and restrictions under the laws of the United States and
the State of Alabama, and to regulation, supervision and regular examination by
the OCC. First National Bank is subject to the power of the OCC to enforce
compliance with applicable banking statutes and regulations.

         First National Bank may generally pay dividends on its stock so long as
payment of such dividends is in compliance with applicable law and regulation. A
national bank may not pay dividends from its stated capital. Additionally, if
losses have been sustained at any time by a national bank equal to or exceeding
its undivided profits then on hand, then no dividend can be paid by the bank,
and all dividends must be paid out of net profits then on hand. The net profits
must take into account all expenses, including losses and provisions for loan
losses. The payment of dividends out of net profits of a national bank is
further limited by a provision of the National Bank Act, which prohibits a
national bank from declaring a dividend on its shares of stock until 10% of the
bank's net profits are transferred to surplus each time dividends are declared,
unless such a transfer would increase the surplus of the bank to an amount
greater than the bank's capital.

         The prior approval of the OCC is required if the total of all dividends
declared by a national bank in any calendar year exceeds the total of its net
profits for that year combined with its net profits for the two preceding years,
less any required transfers to surplus or to funds for the retirement of any
preferred stock. Section 18 of Title 12 of the United States Code provides that
the OCC has the right to prohibit the payment of dividends by a national bank
where such payment is deemed to be an unsafe and unsound banking practice.

         First National Bank is also subject to certain restrictions on the
payment of dividends as a result of the requirement that it maintain adequate
levels of capital in accordance with guidelines promulgated from time to time by
the OCC. In 1989, the OCC issued risk-based capital regulations which require
national banks to maintain minimum capital levels based upon the relative safety
of their assets. Under such regulations, the capital adequacy of First National
Bank is determined in light of the risk, both on- and off-balance sheet,
contained in the bank's assets. Different categories of assets are assigned risk
weightings and, based thereon, are counted at a percentage (from zero to 100%)
of their book value.

         These regulations divide capital between Tier 1 capital, or core
capital, and Tier 2 capital, or supplemental capital. Tier 1 capital consists
primarily of common stock, noncumulative perpetual preferred stock, related
surplus and minority interests in consolidated subsidiaries. Tier 2 capital
consists of varying percentages of the allowance for loan losses, all other
types of preferred stock not included in Tier 1 capital, hybrid capital
instruments and term subordinated debt. Investments in and loans to
unconsolidated banking and finance subsidiaries that constitute capital of those
subsidiaries are excluded from capital. The sum of Tier 1 and Tier 2 capital
constitutes qualifying total capital. The Tier 1 component must comprise at
least 50% of qualifying total capital.

   
         Every national bank is required to maintain a minimum ratio of Tier 1
capital to risk weighted assets (a "Core Capital Ratio") of at least 4% and a
minimum ratio of Tier 1 plus Tier 2 capital to risk weighted assets (a
"Risk-Based Capital Ratio") of at least 8%. As of September 30, 1998, the Core
Capital Ratio for First National Bank was 15.81% and its Risk-Based Capital
Ratio was 17.03%. In addition, national banks are required to achieve and
maintain a ratio of Tier 1 capital to total assets (a "Leverage Capital Ratio")
of at least 3%. As of September 30, 1998, the Leverage Capital Ratio for First
National Bank was 10.68%. Generally, banking organizations are expected to
operate well above the minimum required capital level of 3% unless they meet
certain specified criteria, including that they have the highest regulatory
ratings. Most banking organizations are required to maintain a Leverage Capital
Ratio of 3%, plus an additional cushion of at least 1% to 2%. The guidelines
also
    



                                       74
<PAGE>   78

provide that banking organizations experiencing internal growth or making
acquisitions will be expected to maintain strong capital positions substantially
above the minimum supervisory levels without significant reliance upon
intangible assets.

         Under the Financial Institutions Reform, Recovery and Enforcement Act
of 1989, failure to meet the capital guidelines could subject a banking
institution to a variety of enforcement remedies available to federal regulatory
authorities, including the termination of deposit insurance by the FDIC. The
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
substantially revised the depository institution regulatory and funding
provisions of the Federal Deposit Insurance Act as well as several other federal
banking statutes. Among other things, FDICIA requires the federal banking
regulators to take prompt corrective action in respect of depository
institutions that do not meet minimum capital requirements.

   
         FDICIA divides banks into five different categories, depending on their
level of capital. Under regulations adopted by the OCC, a bank is deemed to be
"well capitalized" if it has a total Risk-Based Capital Ratio of 10% or more, a
Core Capital Ratio of 6% or more and a Leverage Capital Ratio of 5% or more, and
the bank is not subject to an order or capital directive to meet and maintain a
certain capital level. Under such regulations, a bank is deemed to be
"adequately capitalized" if it has a total Risk-Based Capital Ratio of 8% or
more, a Core Capital Ratio of 4% or more and a Leverage Capital Ratio of 4% or
more (unless it receives the highest composite rating at its most recent
examination and is not experiencing or anticipating significant growth, in which
instance it must maintain a Leverage Capital Ratio of 3% or more). Under such
regulations, a bank is deemed to be "undercapitalized" if it has a total
Risk-Based Capital Ratio of less than 8%, a Core Capital Ratio of less than 4%
or a Leverage Capital Ratio of less than 4%. Under such regulations, a bank is
deemed to be "significantly undercapitalized" if it has a Risk-Based Capital
Ratio of less than 6%, a Core Capital Ratio of less than 3% and a Leverage Ratio
of less than 3%. Under such regulations, a bank is deemed to be "critically
undercapitalized" if it has a Leverage Capital Ratio of less than or equal to
2%. In addition, the OCC has the ability to downgrade a bank's classification
(but not to "critically undercapitalized") based on other considerations even if
the bank meets the capital guidelines. According to these guidelines, First
National Bank was classified as "well capitalized" as of September 30, 1998.
    

         In addition, if a national bank is classified as undercapitalized, the
bank is required to submit a capital restoration plan to the OCC. Pursuant to
the FDICIA, an undercapitalized national bank is prohibited from increasing its
assets, engaging in a new line of business, acquiring any interest in any
company or insured depository institution or opening or acquiring a new branch
office, except under certain circumstances. These restrictions also include the
acceptance by the OCC of a capital restoration plan for the bank. Furthermore,
if a national bank is classified as undercapitalized, the OCC may take certain
actions to correct the capital position of the bank, but if a bank is classified
as significantly undercapitalized or critically undercapitalized, the OCC would
be required to take one or more prompt corrective actions. These actions would
include, among other things, requiring:

         1.  Sales of new securities to bolster capital;

         2.  Improvements in management;

         3.  Limits on interest rates paid;

         4.  Prohibitions on transactions with affiliates;

         5.  Termination of certain risky activities; and

         6.  Restrictions on compensation paid to executive officers.




                                       75
<PAGE>   79

         If a national bank is classified as critically undercapitalized, FDICIA
requires the bank to be placed into conservatorship or receivership within 90
days, unless the OCC and the FDIC concur that other action would better achieve
the purposes of the FDICIA regarding prompt corrective action with respect to
undercapitalized banks.

         The capital classification of a bank affects the frequency of
examinations of the bank, impacts the ability of the bank to engage in certain
activities and affects the deposit insurance premiums paid by such bank. Under
the FDICIA, the OCC is required to conduct a full-scope, on-site examination of
every national bank at least once every 12 months. An exception to this rule is
made, however, that provides that national banks (i) with assets of less than
$250 million, (ii) categorized as "well capitalized," (iii) found to be well
managed and its composite rating outstanding and (iv) not subject to a change in
control during the last 12 months, need only be examined by the OCC once every
18 months.

         Under the FDICIA, banks may be restricted in their ability to accept
brokered deposits, depending on their capital classification. "Well capitalized"
banks are permitted to accept brokered deposits, but all banks that are not well
capitalized are not permitted to accept such deposits. The FDIC may, on a
case-by-case basis, permit banks that are adequately capitalized to accept
brokered deposits if the FDIC determines that acceptance of such deposits would
not constitute an unsafe or unsound banking practice with respect to the bank.

         The FDICIA also provides that the FDIC is authorized to assess
insurance premiums on a bank's deposits at a variable rate depending on the
probability that the deposit insurance fund will incur a loss with respect to
the bank. Under prior law, the deposit insurance assessment was a flat rate,
regardless of the likelihood of loss. In this regard, the FDIC has issued
regulations for a transitional risk-based deposit assessment that determines the
deposit insurance assessment rates on the basis of the bank's capital
classification and supervisory evaluations. Each of these categories have three
subcategories, resulting in nine assessment risk classifications. The three
subcategories with respect to capital are "well capitalized," "adequately
capitalized" and "less than adequately capitalized" (which would include
"undercapitalized," "significantly undercapitalized" and "critically
undercapitalized" banks). The three subcategories with respect to supervisory
concerns are "healthy," "supervisory concern" and "substantial supervisory
concern." A bank is deemed "healthy" if it is financially sound with only a few
minor weaknesses. A bank is deemed subject to "supervisory concern" if it has
weaknesses that, if not corrected, could result in significant deterioration of
the bank and increased risk to the Bank Insurance Fund (the "BIF"). A bank is
deemed subject to "substantial supervisory concern" if it poses a substantial
probability of loss to the BIF.

         The federal banking agencies have established guidelines, effective
August 9, 1995, which prescribe standards for depository institutions relating
to internal controls, information systems, internal audit systems, loan
documentation, credit underwriting, interest rate exposure, asset growth and
management compensation. The agencies may require an institution which fails to
meet the standards set forth in the guidelines to submit a compliance plan.

CERTAIN RELATED PARTY TRANSACTIONS

         Certain of the officers, directors and principal shareholders of The
First Corporation and First National Bank, and their affiliates, have deposit
accounts and other transactions with First National Bank, including loans in the
ordinary course of business. All loans or other extensions of credit made by
First National Bank to officers, directors and principal shareholders of The
First Corporation or First National Bank and to affiliates of such persons were
made in the ordinary course of business on substantially the same terms,
including interest rates and collateral, as those prevailing at the time for
comparable transactions with independent third parties and did not involve more
than the normal risk taken by the lender or present other unfavorable features.
All loans made to executive officers and directors are believed to be in
compliance with the Financial Institutions Regulatory and Interest Rate Control
Act of 1978. None of such loans are categorized as



                                       76
<PAGE>   80

nonaccrual, past due, restructured or potential problem loans. Prior to the
Merger, First National Bank expects to continue to enter into transactions in
the ordinary course of business on similar terms with officers, directors and
principal shareholders of The First Corporation, First National Bank and their
affiliates.

LEGAL PROCEEDINGS

         The First Corporation and First National Bank are involved in routine
legal proceedings occurring in the ordinary course of business that, in the
aggregate, are not believed by management of these companies to be material to
the consolidated financial condition and results of operation of the banks.

                      COMPARISON OF RIGHTS OF SHAREHOLDERS


         First Corporation Shareholders, whose rights are governed by the First
Corporation Articles, the First Corporation Bylaws and the ABCA, will become
shareholders of BancorpSouth upon completion of the Merger. As such, the rights
of the former First Corporation Shareholders will be governed by the
BancorpSouth Articles, the BancorpSouth Bylaws and the MBCA.

         While it is impractical to summarize all such differences, set forth
below are the material differences between the rights of First Corporation
Shareholders under The First Corporation's governing documents and governing law
and the rights of BancorpSouth shareholders under the BancorpSouth Articles,
BancorpSouth Bylaws and the MBCA.

VOTING RIGHTS; CUMULATIVE VOTING

         THE FIRST CORPORATION. The First Corporation Articles provide for
cumulative voting by First Corporation Shareholders in elections of members of
the First Corporation Board. Cumulative voting entitles each First Corporation
Shareholder to cast a total number of votes equal to the product of (i) the
number of directors being elected, times (ii) the number of shares held in the
shareholder's name as of the record date. This total number of votes may be cast
for one candidate or distributed among as many candidates as the shareholder
desires. In voting on any matter other than the election of directors, such as
approval of the Merger Agreement, each First Corporation Shareholder entitled to
vote on the matter is entitled to one vote for each share of First Corporation
Common Stock held by the shareholder.

         BANCORPSOUTH. The BancorpSouth Articles provide that each share of
issued and outstanding BancorpSouth Common Stock entitles the holder to one vote
on each matter with respect to which shareholders are entitled to vote. The
BancorpSouth Articles and Bylaws do not provide for cumulative voting by
shareholders.

PREEMPTIVE RIGHTS

         THE FIRST CORPORATION. Each First Corporation Shareholder has the
preemptive right to purchase such shareholder's proportion of the issuance of
any shares of First Corporation Common Stock according to the proportion of such
shareholder's holdings of First Corporation Common Stock, at such price, within
such time and on such terms as shall be fixed and determined by the First
Corporation Board. However, these preemptive rights do not apply to (1)
1,250,000 shares of First Corporation Common Stock which The First Corporation
may issue from time to time, in whole or in part, from authorized and unissued
shares or treasury shares, and (2) shares of First Corporation Common Stock
issued in connection with a merger or consolidation to which The First
Corporation or its direct or indirect subsidiary is a party, or in connection
with the acquisition by The First Corporation or its direct or indirect
subsidiary of all or substantially all of the assets or property of another
corporation or entity.

         BANCORPSOUTH. The BancorpSouth Articles and Bylaws do not provide for
preemptive rights for BancorpSouth shareholders.

CHANGE OF CONTROL

         THE FIRST CORPORATION. The First Corporation Articles and Bylaws do not
provide for the staggered election of members of the First Corporation Board.
Directors of The First Corporation are elected annually for a one-year term and
hold office until the next succeeding annual meeting of First Corporation
Shareholders and until their successors have been elected and qualified, subject
to earlier resignation and removal. The minimum and maximum number of directors
of The First Corporation may be increased or decreased from time to time at any
regular or special meeting of the


                                       79
<PAGE>   83

First Corporation Board or at any annual meeting or at a special meeting of
First Corporation Shareholders. However, a decrease in the number of directors
of the First Corporation Board may not have the effect of shortening the term of
any incumbent director. The First Corporation has not adopted a shareholder
rights plan.

         BANCORPSOUTH. The BancorpSouth Articles contain several provisions
which make a change of control of BancorpSouth more difficult to accomplish
without the approval of the Board of Directors of BancorpSouth, including the
following:

         1.    The BancorpSouth Board is divided into three classes so that
               approximately one-third of the directors will be subject to
               reelection at each annual meeting of the shareholders of
               BancorpSouth;

         2.    The BancorpSouth Bylaws provide that a vote of at least 80% of
               the outstanding shares of BancorpSouth Common Stock is required
               to increase the maximum number of members of the BancorpSouth
               Board unless the BancorpSouth Board recommends such an increase;

         3.    The BancorpSouth Articles provide that the affirmative vote of
               the holders of not less than 80% of the outstanding shares of
               voting stock of BancorpSouth is required in the event that the
               BancorpSouth Board does not recommend to BancorpSouth
               Shareholders a vote in favor of a merger or consolidation of
               BancorpSouth with, or a sale or lease of all or substantially all
               of the assets of BancorpSouth to, any person or entity;

         4.    The affirmative vote of the holders of not less than 80% of the
               outstanding shares of voting stock of BancorpSouth, as well as at
               least 67% of the outstanding shares of voting stock of
               BancorpSouth not held by a person owning or controlling 20% or
               more of BancorpSouth's voting stock ("Controlling Person"), shall
               be required for the approval of a merger, consolidation, or sale
               or lease of all or substantially all of BancorpSouth's assets
               with or to a Controlling Person, except in certain instances; and

         5.    BancorpSouth has implemented a shareholders' rights plan (which
               is commonly referred to as a "poison pill") under which a common
               stock purchase right ("BancorpSouth Right") attaches to and
               trades with each share of BancorpSouth Common Stock (including
               shares of BancorpSouth Common Stock to be issued to First
               Corporation Shareholders in connection with the Merger). Upon the
               occurrence of certain events, including the acquisition of, or
               tender offer for, 20% or more of the outstanding shares of
               BancorpSouth Common Stock by any person or entity, then the
               holders of each such purchase right (except those held by the
               person acquiring the shares or making the tender offer) will be
               entitled to purchase one share of BancorpSouth Common Stock at a
               price equal to 50% of the then current market price.

BOARD OF DIRECTORS

         THE FIRST CORPORATION. The First Corporation Board is to consist of
seven to 25 members, as determined from time to time by resolution of the First
Corporation Shareholders at their annual meeting, and on the date of this
Prospectus Supplement/Proxy Statement the First Corporation Board consisted of
11 members. Any vacancy on the First Corporation Board may be filled by a
majority vote of the remaining directors. Any directorship to be filled by
reason of an increase in the number of directors must be filled by election at
an annual meeting or at a special meeting of First Corporation Shareholders
called for that purpose. Directors of The First Corporation serve one year




                                       80
<PAGE>   84

terms and must be First Corporation Shareholders. Each director of The First
Corporation must own at least 500 shares of First Corporation Common Stock.

         BANCORPSOUTH. The BancorpSouth Board is to consist of nine to 24
members, as determined from time to time by the BancorpSouth Board, and on the
date of this Prospectus Supplement/Proxy Statement consisted of 11 members. The
vote of at least 80% of the outstanding shares of BancorpSouth Common Stock is
required to increase the maximum number of members of the BancorpSouth Board
unless the BancorpSouth Board recommends such an increase. Any vacancy arising
from a director's early retirement from the BancorpSouth Board or an increase in
the number of members of the BancorpSouth Board is to be filled by vote of the
shareholders of BancorpSouth. The members of the BancorpSouth Board are divided
into three classes, with the classes elected for staggered three-year terms.
Each director of BancorpSouth must own at least $200 of par value of
unencumbered shares of BancorpSouth Common Stock.

REMOVAL OF DIRECTORS

         THE FIRST CORPORATION. The First Corporation Bylaws provide that one or
more directors of The First Corporation may be removed by the affirmative vote
of the holders of a majority of shares of First Corporation Common Stock then
entitled to vote at an election of directors at a special meeting called for the
purpose of such removal. First Corporation Shareholders entitled to vote at such
meeting also may elect a successor director or directors for the unexpired term
of the director or directors removed.

         BANCORPSOUTH. The BancorpSouth Articles provide that a director of
BancorpSouth may be removed by the affirmative vote of a majority of the entire
BancorpSouth Board for cause and by the BancorpSouth shareholders only for
cause.

           CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING INFORMATION

         This Prospectus Supplement/Proxy Statement contains certain
forward-looking statements about the financial condition, results of operations
and business of BancorpSouth and The First Corporation and about the combined
companies following the Merger. These statements concern the cost savings,
revenue enhancements and other advantages the companies expect to obtain from
the Merger, the anticipated impact of the Merger on BancorpSouth's financial
performance and earnings estimates for the combined company. These statements
appear in several sections of this Prospectus


                                       83
<PAGE>   87

Supplement/Proxy Statement, including "SUMMARY," "THE MERGER -- Reasons for the
Merger" and "THE MERGER -- Fairness Opinion." Also, the forward-looking
statements generally include any of the words "believes," "expects,"
"anticipates," "intends," "estimates," "plans" or similar expressions.

         Forward-looking statements are not guarantees of future performance.
They involve risks, uncertainties and assumptions. The future results and
shareholder values of BancorpSouth and The First Corporation, and of the
combined companies, may differ materially from those expressed in these
forward-looking statements. Many of the factors that could influence or
determine actual results are unpredictable and not within the control of
BancorpSouth or The First Corporation. In addition, neither BancorpSouth nor The
First Corporation intends to, nor are they obligated to, update these
forward-looking statements after this Prospectus Supplement/Proxy Statement is
distributed, even if new information, future events or other circumstances have
made them incorrect or misleading as of any future date. For all of these
statements, BancorpSouth claims the protection of the safe harbor for
forward-looking statements provided in the Private Securities Litigation Reform
Act of 1995.

         Factors that may cause actual results to differ materially from those
contemplated by these forward-looking statements include, among others, the
following possibilities:

         1.    Cost savings the companies expect from the Merger might not be
               fully realized or realized within the time frame the companies
               anticipate;

         2.    Revenues following the Merger may be lower than expected;

         3.    Loss of deposits, customers or revenues following the Merger may
               be greater than anticipated;

         4.    Competitive pressure among financial services providers in the
               mid-south region of the United States or in the financial
               services industry generally may increase significantly;

         5.    Costs or difficulties related to regulatory requirements involved
               in combining the companies, including the subsidiary banks, may
               be greater than expected;

         6.    Interest rates may change in such a way as to reduce the
               companies' margins;

         7.    General economic or monetary conditions, either nationally or
               regionally, may be less favorable than expected, resulting in a
               deterioration in credit quality or a diminished demand for the

                          INDEPENDENT AUDITOR'S REPORT



The Board of Directors and Shareholders
The First Corporation
Opelika, Alabama

         We have audited the accompanying consolidated statements of financial
condition of The First Corporation and subsidiary as of December 31, 1997 and
1996, and the related statements of income, changes in stockholders' equity, and
cash flows for each of the three years in the period ended December 31, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of The
First Corporation and subsidiary at December 31, 1997 and 1996, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

         A summary of the significant accounting policies of The First
Corporation ("The First Corporation" or the "Company") and subsidiary, which
have been consistently followed in preparing the accompanying financial
statements, is presented to assist the reader in better understanding the
financial statements and other data contained in this report.

BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of The First
Corporation and its wholly owned subsidiary, The First National Bank of Opelika
("First National" or the "Bank"). Significant intercompany balances and
transactions have been eliminated. The accounting and reporting policies of The
First Corporation conform with generally accepted accounting principles and with
practices of the banking industry. In preparing the financial statements, in
accordance with generally accepted accounting principles, management is required
to make estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities as of the
date of the balance sheet and revenues and expenses for the period.
Actual results could differ significantly from those estimates.

         Material estimates that are particularly susceptible to significant
change relate to the determination of the reserve for loan losses and the
disclosures for contingent assets and liabilities. In connection with the
determination of the reserve for loan losses and the valuation of other real
estate, management obtains independent appraisals for significant properties and
properties collateralizing impaired loans.

STATEMENT OF CASH FLOWS

         In the statement of cash flows, cash equivalents consist of cash and
due from banks, interest bearing deposits, and federal funds sold.

INVESTMENT SECURITIES

         First National classifies its securities into two categories: held to
maturity and available for sale. Held to maturity securities are those
securities for which First National has the ability and intent to hold until
maturity. All other securities not included in held to maturity are classified
as available for sale.

         Securities available for sale are recorded at fair value, with
unrealized gains and losses, net of the related tax effect, reported as a
separate component of shareholders' equity until realized. Held to maturity
securities are recorded at cost, and are adjusted for the amortization of
premiums and accretion of discounts to maturity. Transfers of securities between
categories are recorded at fair value at the date of transfer. Unrealized gains
or losses associated with transfers of securities from held to maturity to
available for sale are recorded as a separate component of shareholders' equity.
The unrealized gains or losses included in the separate component of
shareholders' equity for a security transferred from available for sale to held
to maturity are maintained and amortized into earnings over the remaining life
of the security as an adjustment to yield in a manner consistent with the
amortization or accretion of premium or discount on the associated security.

         A decline in the market value of any available for sale or held to
maturity security below cost that is deemed other than temporary results in a
charge to earnings resulting in the establishment of a new cost basis for the
security.


                                      F-7
<PAGE>   96

         Premiums and discounts are amortized and accumulated over the life of
the related security as an adjustment to the yield using the effective interest
method. Dividends and interest income are recognized when earned. Realized gains
and losses for securities classified as available for sale and held to maturity
are included in earnings and are derived using the specific identification
method for determining the amortized cost of securities sold.

         Management determines the appropriate classification of the security at
the time of purchase and reevaluates such designations as of the date of each
statement of condition.

LOANS

         Loans are reported at principal amounts outstanding, less unearned
income and reserve for loan losses.

         Interest on loans is accrued based upon the principal amount
outstanding except for interest on some installment loans, which is generally
credited to income based upon the sum-of-the-years digits method. This method
generally approximates the interest method of income recognition.

         Loans on which the accrual of interest has been discontinued are
designated as nonaccrual loans. Accrual of interest on loans is discontinued
when, in the opinion of management, reasonable doubt exists that the borrower
may be unable to meet payments of interest or principal when they become
contractually due. When a loan is placed on non accrual status, previously
accrued interest is charged to interest income on loans. Interest payments
received on nonaccrual loans are applied as a reduction of principal. Loans are
returned to accruing status only when they are brought fully current with
respect to interest and principal and when, in the judgment of management, the
loans are estimated to be fully collectible as to both principal and interest.
Such interest, when ultimately collected, is recorded as interest income in the
period received. Interest on accruing impaired loans is recognized as long as
such loans do not meet the criteria for nonaccrual classifications.

RESERVE FOR LOAN LOSSES

         The reserve for loan losses is established through provisions for loan
losses charged to operations. Loans are charged against the reserve for loan
losses when management believes that the collection of principal is unlikely.
Subsequent recoveries are added to the reserve. Management's evaluation of the
adequacy of the reserve for loan losses is based on a formal analysis which
assesses the risk within the loan portfolio. This analysis includes
consideration of historical performance, current economic conditions, level of
nonperforming loans, loan concentrations, and review of certain individual
loans.

         Management believes that the reserve for loan losses is adequate. While
management uses available information to recognize losses on loans, future
additions to the reserve for loan losses may be necessary based on changes in
economic conditions. In addition, various regulatory agencies, as an integral
part of their examination process, periodically review the subsidiary bank's
reserve for loan losses. Such agencies may require the subsidiary bank to
recognize additions to the reserve for loan losses based on their judgments
about information available to them at the time of their examination.

         Management, considering current information and events regarding a
borrowers' ability to repay its obligations, considers a loan to be impaired
when the ultimate collectibility of all amounts due, according to the
contractual terms of the loan agreement, is in doubt. When a loan is considered
to be impaired, the amount of impairment is measured based on the present value
of expected future cash flows discounted at the loan's effective interest rate.
If the loan is collateral-dependent, the fair value of the collateral is used to
determine the amount of impairment. Impairment losses are



                                      F-8
<PAGE>   97

included in the reserve for loan losses through a charge to the provision for
losses on loans. Subsequent recoveries are added to the reserve for loan losses.
Cash receipts for accruing loans are applied to principal and interest under the
contractual terms of the loan agreement. Cash receipts on impaired loans for
which the accrual of interest has been discontinued are applied first to
principal and then to interest income.

         The accounting for impaired loans described above applies to all loans,
except for large pools of smaller-balance, homogeneous loans that are
collectively evaluated for impairment, loans that are measured at fair value or
at the lower of cost or fair value, and debt securities. The reserve for loan
losses for large pools of smaller-balance, homogeneous loans is established
through consideration of such factors as changes in the nature and volume of the
portfolio, overall portfolio quality, adequacy of the underlying collateral,
loan concentrations, historical charge-off trends, and economic conditions that
may affect the borrowers' ability to pay.

PREMISES AND EQUIPMENT

         Premises, equipment, and leasehold improvements are reported at cost,
less accumulated depreciation and amortization. The provision for depreciation
is computed using the straight-line or accelerated methods over the estimated
useful lives of the assets.

         Estimated useful lives generally are as follows:

</TABLE>

         Expenditures for maintenance and repairs are charged against income as
incurred. Costs of major additions and improvements are capitalized. The asset
account is relieved of the cost of the item and the allowance for depreciation
and amortization is charged with accumulated depreciation or amortization when
property is disposed of or retired.

OTHER REAL ESTATE

         Other real estate, consisting of properties obtained through
foreclosure or in satisfaction of loans, is reported at the lower of cost or
fair value, determined on the basis of current appraisals, comparable sales, and
other estimates of value obtained principally from independent sources, adjusted
for estimated selling costs. Any excess of the loan balance at the time of
foreclosure over the fair value of the real estate held as collateral is treated
as a loan charge-off. Gain or loss on sale and any subsequent adjustment to the
value are recorded as a component of non-interest expense.

INCOME TAXES

         The First Corporation uses the asset and liability method to account
for income taxes. Under the asset and liability method, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax basis. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

         Fair value estimates are made at a specific point in time, based on
relevant market information and information about the financial instrument.
These estimates do not reflect any premium or discount that could result from
offering for sale, at one time, the Bank's entire holding of a particular
financial instrument. Because no market exists for a portion of the Bank's
financial instruments, fair value estimates are based on judgments regarding
future expected loss experience, current economic conditions, risk
characteristics of various financial instruments, and other factors. These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision. Changes
in assumptions could significantly affect the estimates.

         Fair value estimates are based on existing on- and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not considered
financial instruments. Significant assets and liabilities that are not
considered financial instruments include deferred tax accounts and premises and
equipment. In addition, the tax ramifications related to the realization of the
unrealized gains and losses can have a significant effect on fair value
estimates and have not been considered in any of the estimates.

         The following methods and assumptions were used to estimate the fair
value of each class of financial instruments for which it is practicable to
estimate that value.

CASH AND SHORT-TERM INVESTMENTS

         For those short-term instruments, the carrying amount is a reasonable
estimate of fair value.

SECURITIES

         For securities held to maturity for investment purposes, fair values
are based on quoted market prices or dealer quotes.

LOANS, NET UNEARNED INCOME

         The fair value of loans is estimated by discounting the future cash
flows using the current rates at which similar loans would be made to borrowers
with similar credit ratings and for the same remaining maturities. 

DEPOSITS

         The fair value of demand deposits, savings accounts, and certain money
market deposits is the amount payable on demand at the reporting date. The fair
value of fixed-maturity certificates of deposit and time deposits is estimated
using the rates currently offered for deposits of similar remaining maturities.

LONG-TERM DEBT

         Rates currently available to the Bank for similar terms and remaining
maturities are used to estimate fair value of existing debt.




                                      F-10
<PAGE>   99



COMMITMENTS TO EXTEND CREDIT, STANDBY LETTERS OF CREDIT, AND FINANCIAL
GUARANTEES WRITTEN

         The fair values of commitments are estimated using the fees charged to
enter into similar agreements, taking into account the remaining terms of the
agreements and the present creditworthiness of the counter parties. For
fixed-rate loan commitments, fair values also consider the difference between
current levels of interest rates and the committed rates. The fair values of
guarantees and letters of credit are estimated based on fees currently charged
for similar agreements.

         The following summarizes the fair value of financial instruments at
December 31:

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". This statement establishes standards for reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements. SFAS No. 130 requires all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed in equal prominence with the
other financial statements. The term "comprehensive income" is used in the SFAS
to describe the total of all components of comprehensive income including net
income. "Other comprehensive income" refers to revenues, expenses, gains, and
losses that are included in comprehensive income but excluded from earnings
under current accounting standards. Currently, "other comprehensive income" for
The First Corporation consists of items previously recorded directly in equity
under SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
Securities". SFAS No. 130 is effective for both interim and annual financial
statement periods beginning after December 15, 1997.

NOTE B - RESTRICTIONS ON CASH AND DUE FROM BANKS

         First National is not required to maintain a reserve balance with the
Federal Reserve Bank due to the adequate cash reserves on hand.

NOTE C - SECURITIES

         The carrying and estimated fair value of investment securities are
summarized as follows:

         The Bank's portfolio of securities generally consists of
investment-grade securities. The fair value of securities are determined with
the assistance of an independent pricing service. They are based on available
market data which often reflects transactions of relatively small size and are
not necessarily indicative of the prices at which large amounts of particular
issues could be readily sold or purchased.

         Loans on which the accrual of interest has been discontinued or reduced
amounts to $26,072 at December 31, 1997. If interest on those loans had been
accrued, such additional income would have approximated $3,520. Interest income
on those loans, which is recorded only when received, amounted to $2,699.

         Directors and executive officers, including the directors' and
officers' families and affiliated companies, are loan and deposit customers and
have other transactions with the Bank in the ordinary course of business. Total
loans to these persons (excluding loans which in the aggregate do not exceed
$60,000 to any such person) at December 31, 1997 and 1996 were approximately
$1,568,428 and $1,668,115 respectively. These loans were made in the ordinary
course of business and with substantially the same terms including interest
rates and collateral, as those prevailing at the same time for comparable
transactions with other persons and involve no unusual risk of collectibility.

</TABLE>


         Federal Home Loan Bank advances represent borrowing from the Federal
Home Loan Bank of Atlanta. These advances are secured by Federal Home Bank
stock, carried at $610,300 and three Federal Home Loan Bank notes and two FHLMC
pool certificates with book amount of $6,240,236.


NOTE I - FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

         The Bank is party to financial instruments with off-balance sheet risk
in the normal course of business to meet the financial needs of its customers.
These financial instruments include loan commitments and standby letters of
credit and involve, to varying degrees, elements of credit and interest rate
risk in excess of the amount recognized in the financial statements.



                                      F-16
<PAGE>   105


         The Bank's exposure to credit loss in the event of nonperformance by
the other party to the financial instrument for loan commitments and standby
letters of credit is represented by the contractual amount of those instruments.
The Bank has no significant concentrations of credit risk with any individual
counterparty to originate loans. The total amounts of financial instruments with
off-balance sheet risk as of December 31, 1997 are as follows:

<TABLE>
<S>                                                       <C>
Loan commitments..................................        $    8,991,235
Standby letters of credit.........................        $      482,500

</TABLE>

         Both loan commitments and standby letters of credit have credit risk
essentially the same as that involved in extending loans to customers and are
subject to normal credit approval procedures and policies. Collateral is
obtained based on management's credit assessment of the customers.

NOTE K - PROFIT-SHARING PLAN

         The First Corporation amended and restated as of January 1, 1995 the
Bank's Savings and Profit-Sharing Plan. The Plan was a profit sharing and 401(k)
matching contribution plan. Eligible employees may defer a maximum of 15% of
their salary, not to exceed $9,240, which the first 5% deferred will be matched
by the Bank. The restated Plan is a profit sharing and stock bonus plan
containing Section 401(k) features that intended to qualify under Section 401(a)
of the Internal Revenue Code. The Plan is also designed to be an employee stock
ownership plan under Section 4975(e)(7) of the Code. The contributions to the
Plan were $117,500 for 1997 and $105,168 in 1996.


NOTE L - OFFICERS RETIREMENT AND DEATH BENEFIT PLAN

         The Bank has a non-qualified supplemental officer retirement benefit
plan. The amount of annual benefit is indexed to the financial performance of an
insurance policy over a selected opportunity cost and is designed to increase
each year. The Bank's obligations under this plan are unfunded; however, the
Bank has purchased life insurance policies on each insurable officer which are
actuarially designed to offset the annual expenses associated with the plan and
will, given reasonable actuarial assumptions, provide over time a complete
recovery of all plan costs.

         The life insurance benefit for each officer is the total death benefit
of the policy less the greater of the cash value or an amount equal to the
premiums paid for the policy plus a pro rata share of any interest due.


NOTE M - INCENTIVE STOCK OPTION PLAN

         The Company has an incentive stock option plan for certain key
employees that provide for the granting of options to purchase up to 20,000
shares of the Company's common stock. The terms of the options granted are
determined by the recommendation of the Stock Option Committee and approved by
the Board of Directors; however, no options may be granted after ten years from
the plans' adoption and no options may be exercised beyond ten years from the
date granted. The option price per share of incentive stock options can not be
less than the fair market value of the common stock on the date of grant. On
December 12, 1995, the Company granted options for 10,000 shares exercisable
only to the extent that optionees have acquired a vested interest according to
the option plan.

NOTE N - REGULATORY CAPITAL REQUIREMENTS


         First National has always placed great emphasis on maintaining a strong
capital base and continues to exceed all minimum regulatory capital
requirements. Management is committed to maintaining a capital level sufficient
to assure shareholders, customers, and regulators that First National is
financially sound, and to enable the Bank to sustain an appropriate degree of
leverage to provide a desirable level of profitability.

         Regulators use a risk-adjusted calculation to aid them in their
determination of capital adequacy by weighting assets based on the credit risk
associated with on- and off-balance sheet assets. The majority of these
risk-weighted assets are on-balance sheet assets for First National in the form
of loans. A small portion of risk-weighted assets are considered off-balance
sheet assets and are primarily made up of letters of credit and loan commitments
that First National enters into in the normal course of business. Capital is
categorized into two types: Tier I and Tier II. The capital guidelines used by
regulators require an 8% total risk-based capital ratio of which 4% must be Tier
I capital. Additionally, the regulatory agencies define a well-capitalized bank
as one which has a leverage ratio of at least 5%, a Tier I capital ratio of at
least 6%, and a total risk-based capital ratio of at least 10%. At the end of
1997, First National was in excess of the minimum capital requirements with a
Tier I capital ratio of 15.36% and a total risk-based capital ratio of 16.60%,
compared to Tier I and total risk-based capital ratios of 16.95% and 18.20%,
respectively, in 1996.

penalty, terminate this Agreement by giving prior written notice thereof to
BancorpSouth on the Determination Date, unless, within 24 hours following the
giving of such notice, BancorpSouth agrees with the Company to adjust the
Exchange Ratio to an amount proposed by the Company that is not greater than the

reason of any reclassification, recapitalization, split-up, combination,
exchange of shares or readjustment, or a stock dividend thereon shall be
declared with a record date within said period (any such event, a "Adjustment

of a debt previously contracted (any such shares of Company Common Stock, and
shares of BancorpSouth Common Stock which are similarly held, whether held
directly or indirectly by BancorpSouth or the Company, being referred to herein
as "DPC Shares")) shall be canceled and shall cease to exist and no stock of
BancorpSouth or other consideration shall be delivered in exchange therefor. All

                  (f) Notwithstanding anything in this Agreement to the
contrary, shares of Company Common Stock which are outstanding immediately prior
to the Effective Time and with respect to which dissenters' rights shall have
been properly demanded in accordance with Article 13 of the ABCA ("Company
Dissenting Shares") shall not be converted into the right to receive, or be
exchangeable for, BancorpSouth Common Stock or cash in lieu of fractional shares
but, instead, the holders thereof shall be entitled to payment of the "fair
value" of such Company Dissenting Shares in accordance with the provisions of
Section 13 of the ABCA, provided, however, that if any holder fails to satisfy
the requirements of Article 13 of the ABCA, such holder or holders (as the case
may be) shall not be entitled to payment for such shares of Company Common Stock
under such Article, and each of such shares shall thereupon be deemed to have
been converted into the right to receive, and to have become exchangeable for,
as of the Effective Time, BancorpSouth Common Stock and/or cash in lieu of
fractional shares, without any interest thereon, as provided in Section 1.4(a)
and Article II hereof.

                  (g) BancorpSouth may terminate this Agreement if cash payments
in respect of fractional shares or dissenter's rights exceed the amount
permissible for the utilization of pooling of interests accounting treatment.

to purchase shares of Company Common Stock (each a "Company Option") which is
outstanding and unexercised immediately prior thereto shall cease to represent a
right to acquire shares of Company Common Stock and shall be replaced by an
option issued under the appropriate stock option plan of BancorpSouth; provided
that new options shall only be issued to cover 3200 of the current 8000 shares
subject to Company Options and the remainder shall terminate prior to the
Effective Time, with new option being issued pro rata from such amount to
holders of Company Options:

                           (1) the number of shares of BancorpSouth Common Stock
                  to be subject to the new option shall be equal to the product
                  of the number of shares of Company Common Stock subject to the
                  original option and the Exchange Ratio, provided that any
                  fractional shares of BancorpSouth Common Stock resulting from
                  such multiplication shall be rounded down to the nearest whole
                  share; and

                           (2) the exercise price per share of BancorpSouth
                  Common Stock under the new option shall be equal to the
                  exercise price per share of Company Common Stock under the
                  original option divided by the Exchange Ratio, provided that
                  such exercise price shall be rounded down to the nearest cent.
                  The adjustment provided herein with respect to any options
                  which are incentive stock options" (as defined in Section 422
                  of the Internal Revenue Code of 1986, as amended (the "Code"))
                  shall be and is intended to be effected in a manner which is
                  consistent with Section 424(a) of the Code and, to the extent
                  it is not so consistent, such Section 424(a) shall override
                  anything to the contrary contained herein. The duration and
                  other terms of the new option shall be the same as the
                  original option except that all references to the Company
                  shall be deemed to be references to BancorpSouth.

                  (b) Prior to the Effective Time, BancorpSouth shall reserve
for issuance the number of shares of BancorpSouth Common Stock necessary to
satisfy BancorpSouth's obligations under this Section 1.5.

Certificate or Certificates a form letter of transmittal (which shall specify

shall pass, only upon delivery of the Certificates to the Exchange Agent) and
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing the shares of BancorpSouth Common Stock and the

represented by such Certificate or Certificates shall have been converted
pursuant to this Agreement. The Company shall have the right to review both the
letter of transmittal and the instructions prior to the Effective Time and
provide reasonable comments thereon. Upon surrender of a Certificate for
exchange and cancellation to the Exchange Agent, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor and the Exchange Agent shall mail to such holder
within three business days of such surrender to the Exchange Agent (x) a
certificate representing that number of whole shares of BancorpSouth Common

right to receive in respect of the Certificate surrendered pursuant to the
provisions of this Article II, and the Certificate so surrendered shall
forthwith be canceled. No interest will be paid or accrued on the cash in lieu
of fractional shares and unpaid dividends and distributions, if any, payable to
holders of Certificates.

                  (b) No dividends or other distributions declared after the
Effective Time with respect to BancorpSouth Common Stock and payable to the

which theretofore had become payable with respect to shares of BancorpSouth
Common Stock represented by such Certificate.

                  (c) If any certificate representing shares of BancorpSouth
Common Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it shall be a condition of the
issuance thereof that the Certificate so surrendered shall be properly endorsed
(or accompanied by an appropriate instrument of transfer) and otherwise in
proper form for transfer, and that the person requesting such exchange shall pay
to the Exchange Agent in advance any transfer or other taxes required by reason
of the issuance of a certificate representing shares of BancorpSouth Common
Stock in any name other than that of the registered holder of the Certificate
surrendered, or required for any other reason, or shall establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
payable.

no certificates or scrip representing fractional shares of BancorpSouth Common
Stock shall be issued upon the surrender for exchange of Certificates, no
dividend or distribution with respect to BancorpSouth Common Stock shall be
payable on or with respect to any fractional share, and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a shareholder of BancorpSouth. In lieu of the issuance of any such fractional
share, BancorpSouth shall pay to each former stockholder of the Company who
otherwise would be entitled to receive a fractional share of BancorpSouth Common
Stock an amount in cash equal to the product of (x) the Average Closing Price
and (y) the fraction of a share of BancorpSouth Common Stock which such holder
would otherwise be entitled to receive pursuant to Article I hereof.

                  (f) Any portion of the Exchange Fund that remains unclaimed by
the shareholders of the Company for 12 months after the Effective Time shall be

complied with this Article II shall thereafter look only to BancorpSouth for
payment of their shares of BancorpSouth Common Stock, cash in lieu of fractional
shares and unpaid dividends and distributions on BancorpSouth Common Stock
deliverable in respect of each share of Company Common Stock such stockholder
holds as determined pursuant to this Agreement, in each case, without any
interest thereon. Notwithstanding the foregoing, none of BancorpSouth, the
Company, the Exchange Agent or any other person shall be liable to any former
holder of shares of Company Common Stock for any amount properly delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

                  (g) In the event any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
BancorpSouth, the posting by such person of a bond in such amount as
BancorpSouth may direct as indemnity against any claim that may be made against
it with respect to such Certificate, the Exchange Agent will issue in exchange
for such lost, stolen or destroyed Certificate the shares of BancorpSouth Common
Stock and cash in lieu of fractional shares deliverable in respect thereof
pursuant to this Agreement.

                  (d) authorize or permit any of its officers, directors,
employees or agents to directly or indirectly solicit, initiate, facilitate or
encourage any inquiries relating to, or the making of any proposal which
constitutes, a "takeover proposal" (as defined below), or participate in any
discussions or negotiations, or provide third parties with any nonpublic
information, relating to any 




                                      A-23
<PAGE>   135

such inquiry or proposal or otherwise facilitate any effort or attempt to make a
takeover proposal; provided, however, that the Company may communicate
information about any such takeover proposal to its shareholders if, in the
judgment of the Company's Board of Directors, based upon the written advice of
outside counsel addressed to the Company and BancorpSouth, such communication is
required under applicable law, provided further, however, that the Company may,
and may authorize and permit its officers, directors, employees or agents to,
(i) provide or cause to be provided such information, and (ii) participate in
such discussions or negotiations, if in the judgment of the Company's Board of
Directors, based upon the written advice of outside counsel addressed to the
Company and BancorpSouth, the failure to do so would cause the members of such
Board of Directors to breach their fiduciary duties under applicable laws. The
Company will immediately cease and cause to be terminated any existing
activities, discussions or negotiations previously conducted with any parties
other than BancorpSouth with respect to any of the foregoing. The Company will
take all actions necessary or advisable to inform the appropriate individuals or
entities referred to in the first sentence hereof of the obligations undertaken
in this Section 6.1(d). The Company will notify BancorpSouth immediately if any
such inquiries or takeover proposals are received by, any such information is
requested from, or any such negotiations or discussions are sought to be
initiated or continued with, the Company, and the Company will promptly (within
24 hours) inform BancorpSouth in writing of all of the relevant details with
respect to the foregoing including the material terms and conditions of such
request or takeover proposal and the identity of the person or group making such
request or proposal. The Company will keep BancorpSouth fully informed of the
status and details (including amendments or proposed amendments) of any such
request or takeover proposal. As used in this Agreement, "takeover proposal"
shall mean any tender or exchange offer, proposal for a merger, consolidation or
other business combination involving the Company or any Subsidiary of the
Company or any proposal or offer to acquire in any manner a substantial equity
interest in, or a substantial portion of the assets of, the Company or any
Subsidiary of the Company other than the transactions contemplated or permitted
by this Agreement and the Stock Option Agreement;

                  (e) make any capital expenditures other than those which are

                  (f) enter into any new line of business or cease to carry on
their respective businesses in the ordinary course of business consistent with
past practices;

                  (g) acquire or agree to acquire, by merging or consolidating
with, or by purchasing a substantial equity interest in or a substantial portion
of the assets of, or by any other manner, any business or any corporation,
partnership, association or other business organization or division thereof or
otherwise acquire any assets, which would be material, individually or in the
aggregate, to the Company, or which could reasonably be expected to impede or
delay consummation of the Merger, other than in connection with foreclosures,
settlements in lieu of foreclosure or troubled loan or debt restructurings in
the ordinary course of business consistent with past practices;

                  (h) except as contemplated by Article III hereto, take any
action that is intended or may reasonably be expected to result in any of its

employee or pay any benefit not required by any Plan or agreement as in effect

options, stock appreciation rights, restricted stock, restricted stock units or
performance units or shares).

consistent with past practice, sell, lease, encumber, assign or otherwise

their respective properties is bound, other than the renewal in the ordinary
course of business of any lease the term of which expires prior to the Closing

agreement to which the Company or any of its affiliates is a party as of the
date hereof;

excess of $2,000,000; or

this Agreement or consented to in writing by the Company, BancorpSouth shall
not, and shall not permit any of its Subsidiaries to:

                  (a) except as contemplated by Article III hereto, take any
action that is intended or may reasonably be expected to result in any of its
representations and warranties set forth in this 




                                      A-25
<PAGE>   137

Agreement being or becoming untrue, or in any of the conditions to the Merger

both BancorpSouth's obligations to Company pursuant to this Agreement and
obligations to any such other party pursuant to any such agreement;

                  (f) take any action that would unreasonably interfere with the
operations or the customers of the Company or Opelika, jeopardize the business
of the Company or Opelika, including the contacting of Opelika customers or,

                                   ARTICLE VII
                              ADDITIONAL AGREEMENTS

         7.1. Regulatory Matters.

                  (a) BancorpSouth and the Company shall promptly prepare and
file with the SEC the Proxy Statement, and BancorpSouth shall promptly prepare
and file with the SEC the S-4, in which the Proxy Statement will be included as
a prospectus. Each of the Company and BancorpSouth shall use its reasonable best
efforts to have the S-4 declared effective under the Securities Act as promptly
as practicable after such filing, and the Company shall thereafter mail the
Proxy Statement to its shareholders. BancorpSouth shall also use its reasonable
best efforts to obtain all necessary state securities law or "Blue Sky" permits
and approvals required to carry out the transactions contemplated by this
Agreement.

                  (b) The parties hereto shall cooperate with each other and use
their reasonable best efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, and
to obtain as promptly as practicable all permits, consents, approvals and
authorizations of all third parties and Governmental Entities which are
necessary or advisable to consummate the transactions contemplated by this
Agreement (including, without limitation, the Merger). The Company and
BancorpSouth shall have the right to review in advance, and to the extent
practicable each will consult the other on, in each case subject to applicable
laws relating to the exchange of information, all the information relating to
the Company or BancorpSouth, as the case may be, and any of their respective
Subsidiaries, which appears in any filing made with, or written materials
submitted to, any third party or any Governmental Entity in connection with the
transactions contemplated by this Agreement. In exercising the foregoing right,
each of the parties hereto shall act reasonably and as promptly as practicable.
The parties hereto agree that they will consult with each other with respect to
the obtaining of all permits, consents, approvals and authorizations of all
third parties and Governmental Entities necessary or advisable 




                                      A-26
<PAGE>   138

to consummate the transactions contemplated by this Agreement and each party
will keep the other apprised of the status of matters relating to completion of
the transactions contemplated herein.

                  (c) BancorpSouth and the Company shall, upon request, furnish
each other with all information concerning themselves, their Subsidiaries,
directors, officers and shareholders and such other matters as may be reasonably
necessary or advisable in connection with the Proxy Statement, the S-4 or any
other statement, filing, notice or application made by or on behalf of
BancorpSouth, the Company or any of their respective Subsidiaries to any
Governmental Entity in connection with the Merger and the other transactions
contemplated by this Agreement.

                  (d) BancorpSouth and the Company shall promptly furnish each
other with copies of written communications received by BancorpSouth or the
Company, as the case may be, or any of their respective Subsidiaries, Affiliates
or Associates (as such terms are defined in Rule 12b-2 under the Exchange Act as
in effect on the date of this Agreement) from, or delivered by any of the
foregoing to, any Governmental Entity in respect of the transactions
contemplated hereby.

         7.2.     Access to Information.

                  (a) Upon reasonable notice and subject to applicable laws
relating to the exchange of information, each party shall, and shall cause each
of its Subsidiaries to, afford to the officers, employees, accountants, counsel
and other representatives (each, a "Representative") of the other party, access
during normal business hours during the period prior to the Effective Time to
all its properties, books, contracts, commitments, records, officers, employees,
accountants, counsel and other representatives and, during such period, it
shall, and shall cause its Subsidiaries to, make available to the other party
all information concerning its business, properties and personnel as the other
party may reasonably request. In addition, the Company and Opelika shall permit
a Representative of BancorpSouth to have access to the premises and observe the
operations of the Company or Opelika, as the case may be, without interfering
with the operations of the Company or Opelika and only during normal business
hours and to attend each meeting of their respective Boards of Directors and
committees thereof (other than during discussions regarding this Agreement, the
Stock Option Agreement, and the transactions contemplated hereby and thereby).
Neither party nor any of its Subsidiaries shall be required to provide access to
or to disclose information where such access or disclosure would violate or
prejudice the rights of its customers or its relationship with such customers,
jeopardize any attorney-client privilege or contravene any law, rule,
regulation, order, judgment, decree, fiduciary duty or binding agreement entered
into prior to the date of this Agreement. Such party shall identify the nature
of the limitation on access and disclosure, and the parties hereto will make
appropriate substitute disclosure arrangements under circumstances in which the
restrictions of the preceding sentence apply.

                  (b) All information furnished to BancorpSouth pursuant to
Section 7.2(a) shall be subject to, and BancorpSouth shall hold all such
information in confidence in accordance with, the provisions of the
confidentiality agreement dated August 10, 1998 (the "Confidentiality
Agreement"), between BancorpSouth and the Company. The Company shall have the
same obligations to BancorpSouth under the Confidentiality Agreement with
respect to information furnished to the Company pursuant to Section 7.2(a) as if
the Company were the receiving party under such Confidentiality Agreement.

                  (c) Notwithstanding anything in the Confidentiality Agreement
or any other agreement to the contrary, no provision of the Confidentiality
Agreement or investigation by either of the parties or their respective
representatives shall affect the representations, warranties, covenants or
agreements of the other set forth herein and the parties shall remain
responsible for the same.

<PAGE>   139

         7.3. Shareholder Meeting. The Company shall take all steps necessary to
duly call, give notice of, convene and hold a meeting of its shareholders to be
held as soon as is reasonably practicable after the date on which the S-4
becomes effective for the purpose of voting upon the approval and adoption of
this Agreement. The Company will, through its Board of Directors, recommend to
its shareholders approval of this Agreement and the transactions contemplated
hereby and such other matters as may be submitted to its shareholders in
connection with this Agreement.

         7.4. Legal Conditions to Merger. Each of BancorpSouth and the Company
shall, and shall cause its Subsidiaries to, use their reasonable best efforts
(a) to take, or cause to be taken, all actions necessary, proper or advisable to
comply promptly with all legal requirements which may be imposed on such party
or its Subsidiaries with respect to the Merger and, subject to the conditions
set forth in Article VIII hereof, to consummate the transactions contemplated by
this Agreement and (b) to obtain (and to cooperate with the other party to
obtain) any consent, authorization, order or approval of, or any exemption by,
any Governmental Entity and any other third party which is required to be
obtained by the Company or BancorpSouth or any of their respective Subsidiaries
in connection with the Merger and the other transactions contemplated by this
Agreement, and to comply with the terms and conditions of such consent,
authorization, order or approval.

         7.5. Affiliates. Each of BancorpSouth and the Company shall use its
reasonable best efforts to cause each director, executive officer and other
person who is an "affiliate" (for purposes of Rule 145 under the Securities Act
and for purposes of qualifying the Merger for "pooling-of-interests" accounting
treatment) of such party to deliver to the other party hereto, as soon as
practicable after the date of this Agreement, a written agreement, in the form
of Exhibit 7.5(a) hereto (in the case of affiliates of BancorpSouth) or Exhibit
7.5(b) hereto (in the case of affiliates of the Company).

         7.6. Stock Exchange Listing. BancorpSouth shall make all filings
required of it to cause the shares of BancorpSouth Common Stock to be issued in
the Merger to be approved for listing on the NYSE, subject to official notice of
issuance, as of the Effective Time.

         7.7. Employee Benefit Plans; Existing Agreements.

                  (a) As of the Effective Time, the employees of the Company and
its Subsidiaries (the "Company Employees") shall be eligible to participate in
BancorpSouth's employee benefit plans in which similarly situated employees of
BancorpSouth or BancorpSouth Bank participate, to the same extent as similarly
situated employees of BancorpSouth or BancorpSouth Bank (it being understood
that inclusion of Company Employees in BancorpSouth's employee benefit plans may
occur at different times with respect to different plans).

                  (b) With respect to each BancorpSouth Plan that is an
"employee benefit plan," as defined in Section 3(3)of ERISA, for purposes of
determining eligibility to participate, vesting, and entitlement to benefits,
including for severance benefits and vacation entitlement (but not for accrual
of pension benefits or 401(k) eligibility), service with the Company (or
predecessor employers to the extent the Company provides past service credit)
shall be treated as service with BancorpSouth; provided; however, that such
service shall not be recognized to the extent that such recognition would result
in a duplication or increase of benefits. Such service also shall apply for
purposes of satisfying any waiting periods, evidence of insurability
requirements, or the application of any preexisting condition limitations. Each
BancorpSouth Plan shall waive pre-existing condition limitations to the same
extent waived under the applicable Company Plan. Company Employees shall be
given credit for amounts paid under a corresponding benefit plan during the same
period for purposes of applying deductibles, copayments and out-of-pocket
maximums as though such amounts had been paid in accordance with the terms and
conditions of BancorpSouth Plan.

                  (c) As of the Effective Time, BancorpSouth shall assume and
honor and shall cause the appropriate Subsidiaries of BancorpSouth to assume and
to honor in accordance with their 




                                      A-28
<PAGE>   140

terms all employment, severance and other compensation agreements and
arrangements existing prior to the execution of this Agreement which are between
the Company or any of its Subsidiaries and any director, officer or employee
thereof and which have been disclosed in the Company Disclosure Schedule.

                  (d) BancorpSouth and the Company agree to cooperate and take
all reasonable actions to effect the merger of any employee benefit plan that is
intended to be qualified under Section 401(a) of the Code into the appropriate
tax-qualified retirement plan of BancorpSouth after the Merger is completed, so
that such plan merger satisfies the requirements of Section 414(l) of the Code;
provided, however, that BancorpSouth shall not be obligated to effect such a
merger of a plan unless such plan is fully funded under Section 412 of the Code
and Section 302 of ERISA, to the extent applicable, and the merger would not
jeopardize the tax-qualified status of any BancorpSouth Plan.

         7.8.     Indemnification.

                  (a) In the event of any threatened or actual claim, action,
suit, proceeding or investigation, whether civil, criminal or administrative,
including, without limitation, any such claim, action, suit, proceeding or
investigation in which any person who is now, or has been at any time prior to
the date of this Agreement, or who becomes prior to the Effective Time, a
director, officer or employee of the Company or any of its Subsidiaries (the
"Indemnified Parties") is, or is threatened to be, made a party based in whole
or in part on, or arising in whole or in part out of, or pertaining to (i) the
fact that he is or was a director, officer or employee of the Company, any of
the Subsidiaries of the Company or any of their respective predecessors or
affiliates or (ii) this Agreement or any of the transactions contemplated
hereby, whether in any case asserted or arising before or after the Effective
Time, the parties hereto agree to cooperate and use their best efforts to defend
against and respond thereto. It is understood and agreed that after the
Effective Time, BancorpSouth shall indemnify and hold harmless, as and to the
extent permitted by law, each Indemnified Party against any losses, claims,
damages, liabilities, costs, expenses (including reasonable attorney's fees and
expenses in advance of the final disposition of any claim, suit, proceeding or
investigation to each Indemnified Party to the fullest extent permitted by law
upon receipt of any undertaking required by applicable law), judgments, fines
and amounts paid in settlement in connection with any such threatened or actual
claim, action, suit, proceeding or investigation, and in the event of any such
threatened or actual claim, action, suit, proceeding or investigation (whether
asserted or arising before or after the Effective Time), the Indemnified Parties
may retain counsel reasonably satisfactory to them after consultation with
BancorpSouth; provided, however, that (1) BancorpSouth shall have the right to
assume the defense thereof and upon such assumption BancorpSouth shall not be
liable to any Indemnified Party for any legal expenses of other counsel or any
other expenses subsequently incurred by any Indemnified Party in connection with
the defense thereof, except that if BancorpSouth elects not to assume such
defense or counsel for the Indemnified Parties reasonably advises that there are
issues which raise conflicts of interest between BancorpSouth and the
Indemnified Parties, the Indemnified Parties may retain counsel reasonably
satisfactory to them after consultation with BancorpSouth, and BancorpSouth
shall pay the reasonable fees and expenses of such counsel for the Indemnified
Parties, (2) BancorpSouth shall in all cases be obligated pursuant to this
paragraph to pay for only one firm of counsel for all Indemnified Parties, (3)
BancorpSouth shall not be liable for any settlement effected without its prior
written consent (which consent shall not be unreasonably withheld) and (4)
BancorpSouth shall have no obligation hereunder to any Indemnified Party when
and if a court of competent jurisdiction shall ultimately determine, and such
determination shall have become final and nonappealable, that indemnification of
such Indemnified Party in the manner contemplated hereby is prohibited by
applicable law. Any Indemnified Party wishing to claim Indemnification under
this Section 7.8, upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify BancorpSouth thereof, provided that the
failure to so notify shall not affect the obligations of BancorpSouth under this
Section 7.8 except to the extent such failure to notify 




                                      A-29
<PAGE>   141

materially prejudices BancorpSouth. BancorpSouth's obligations under this
Section 7.8 shall continue in full force and effect without time limit from and
after the Effective Time.

                  (b) BancorpSouth shall cause the persons serving as officers
and directors of the Company immediately prior to the Effective Time to be
covered for a period of three years from the Effective Time by the directors'
and officers' liability insurance policy maintained by the Company (provided
that BancorpSouth may substitute therefor policies of at least the same coverage
and amounts containing terms and conditions which are not less advantageous than
such policy) with respect to acts or omissions occurring prior to the Effective
Time which were committed by such officers and directors in their capacity as
such; provided, however, that in no event shall BancorpSouth be required to
expend on an annual basis more than 125% of the current amount expended by the
Company (the "Insurance Amount") to maintain or procure insurance coverage, and
further provided that if BancorpSouth is unable to maintain or obtain the
insurance called for by this Section 7.8(b), BancorpSouth shall use all
reasonable efforts to obtain as much comparable insurance as is available for
the Insurance Amount.

                  (c) In the event BancorpSouth or any of its successors or
assigns (i) consolidates with or merges into any other person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger, or (ii) transfers or conveys all or substantially all of its properties
and assets to any person, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of
BancorpSouth assume the obligations set forth in this section.

                  (d) The provisions of this Section 7.8 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party and his or
her heirs and representatives.

         7.9. Additional Agreements. In case at any time after the Effective
Time any further action is necessary or desirable to carry out the purposes of
this Agreement or to vest the Surviving Corporation with full title to all
properties, assets, rights, approvals, immunities and franchises of any of the
parties to the Merger, the proper officers and directors of each party to this
Agreement and their respective Subsidiaries shall take all such necessary action
as may be reasonably requested by BancorpSouth.

         7.10. [INTENTIONALLY OMITTED].

         7.11. Stock Option Agreement. Contemporaneously with the execution and
delivery of this Agreement, the Company and BancorpSouth shall execute and
deliver the Stock Option Agreement.

         7.12. Data Processing Conversion. BancorpSouth shall take all steps
necessary and appropriate to cause a smooth, orderly data processing conversion
in connection with the consummation of the Merger and shall initiate appropriate
training of Company and Opelika personnel sufficiently in advance of the
Effective Time to permit Company and Opelika personnel to continue the
operations of the Company and Opelika without undue interruption after the
Merger. Company and Opelika personnel shall cooperate fully with BancorpSouth in
its efforts to provide the training required by this Section 7.12.

         7.13 Publication of Combined Results. As soon as practical after the
date that thirty days of combined financial results of the Company and
BancorpSouth are available, BancorpSouth shall publish such results by press
release or the making of an appropriate filing under the Exchange Act.

         7.14 BancorpSouth Board Approval. The appropriate officers of
BancorpSouth shall take all action necessary to have the ratification, approval,
and adoption of this Agreement and the transactions contemplated hereby to be
considered by the BancorpSouth Board of Directors at its August 26, 1998 board
meeting.

                  (d) Federal Tax Opinion. BancorpSouth shall have received an
opinion from Waller Lansden Dortch & Davis, PLLC, counsel to BancorpSouth
("BancorpSouth's Counsel"), in form and substance reasonably satisfactory to
BancorpSouth, dated the Effective Time, substantially to the effect that, on the
basis of facts, representations and assumptions set forth in such opinion which
are consistent with the state of facts existing at the Effective Time, the
Merger will be treated as a reorganization within the meaning of Section 368(a)
of the Code and that, accordingly, for federal income tax purposes:

                           (i) No gain or loss will be recognized by 
                  BancorpSouth or the Company as a result of the Merger;

                           (ii) No gain or loss will be recognized by the
                  shareholders of the Company who exchange all of their Company
                  Common Stock solely for BancorpSouth Common Stock pursuant to
                  the Merger (except with respect to cash received in lieu of a
                  fractional share interest in BancorpSouth Common Stock); and

                           (iii) The aggregate tax basis of BancorpSouth Common
                  Stock received by shareholders who exchange all of their
                  Company Common Stock solely for BancorpSouth Common Stock
                  pursuant to the Merger will be the same as the aggregate tax
                  basis of the Company Common Stock surrendered in exchange
                  therefor (reduced by any amount allocable to a fractional
                  share interest for which cash is received).

                  In rendering such opinion, BancorpSouth's Counsel may require
and shall be entitled to rely upon representations and covenants, including
those contained in certificates of officers of BancorpSouth, the Company and
others, reasonably satisfactory in form and substance to such counsel.

                  (e) Employment Agreement. William C. Kent shall have entered
into a written employment agreement with BancorpSouth containing non-competition
provisions satisfactory to BancorpSouth in its reasonable discretion.

                  (f) Legal Opinion. BancorpSouth shall have received an opinion
from Jenkens & Gilchrist, in form and substance reasonably satisfactory to
BancorpSouth, dated the Effective Time, relating to the enforceability of this
Agreement and such other matters as BancorpSouth may reasonably request;

rely upon an opinion of Alabama counsel addressed to it or may cause such
opinion to be issued directly to BancorpSouth.

                  (g) Pooling Treatment. BancorpSouth shall be satisfied that
the Merger may be accounted for using the "pooling of interests" accounting
method.

                  (h) Board Approval. This Agreement and the transactions
contemplated hereby shall have been ratified, approved, and adopted by the
Boards of Directors of both BancorpSouth and BancorpSouth Bank.

         8.3. Conditions to Obligations of the Company. The obligation of the
Company to effect the Merger is also subject to the satisfaction or waiver by
the Company at or prior to the Effective Time of the following conditions:

                  (a) Representations and Warranties. (i) Subject to Section
3.2, the representations and warranties of BancorpSouth set forth in this
Agreement (other than those set forth in Section 5.2) shall be true and correct
as of the date of this Agreement and (except to the extent such representations
and warranties speak as of an earlier date) as of the Closing Date as 




                                      A-32
<PAGE>   144

though made on and as of the Closing Date; and (ii) the representations and
warranties of BancorpSouth set forth in Section 5.2 of this Agreement shall be
true and correct in all material respects (without giving effect to Section 3.2
of this Agreement) as of the date of this Agreement and (except to the extent
such representations and warranties speak as of an earlier date) as of the
Closing Date as though made on and as of the Closing Date. The Company shall
have received a certificate signed on behalf of BancorpSouth by the Chief
Executive Officer and the principal financial officer of BancorpSouth to the
foregoing effect.

                  (b) Performance of Obligations of BancorpSouth. BancorpSouth
shall have performed in all material respects all obligations required to be
performed by it under this Agreement at or prior to the Closing Date, and the
Company shall have received a certificate signed on behalf of BancorpSouth by
the Chief Executive Officer and the principal financial officer of BancorpSouth
to such effect.

                  (c) No Pending Governmental Actions. No proceeding initiated
by any Governmental Entity seeking an Injunction shall be pending.

                  (d) Federal Tax Opinion. The Company shall have received an
opinion from Jenkens & Gilchrist (the "Company's Counsel"), in form and

substantially to the effect that, on the basis of facts, representations and
assumptions set forth in such opinion which are consistent with the state of
facts existing at the Effective Time, the Merger will be treated as a
reorganization within the meaning of Section 368(a) of the Code and that,
accordingly, for federal income tax purposes:

                            (i) No gain or loss will be recognized by
                  BancorpSouth or the Company as a result of the Merger;

                           (ii) No gain or loss will be recognized by the
                  shareholders of the Company who exchange all of their Company
                  Common Stock solely for BancorpSouth Common Stock pursuant to
                  the Merger (except with respect to cash received in lieu of a
                  fractional share interest in BancorpSouth Common Stock); and

                           (iii) The aggregate tax basis of BancorpSouth Common
                  Stock received by shareholders who exchange all of their
                  Company Common Stock solely for BancorpSouth Common Stock
                  pursuant to the Merger will be the same as the aggregate tax

                  therefor (reduced by any amount allocable to a fractional
                  share interest for which cash is received).

                  In rendering such opinion, the Company's Counsel may require
and shall be entitled to rely upon representations and covenants, including
those contained in certificates of officers of BancorpSouth, the Company and
others, reasonably satisfactory in form and substance to such counsel.

                  (e) Fairness Opinion. Prior to the mailing of Proxy Statement,
the Company shall have received an opinion from Alex Sheshunoff & Co. to the

                                   ARTICLE IX
                            TERMINATION AND AMENDMENT

         9.1. Termination. This Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval of the matters presented in
connection with the Merger by the shareholders of both the Company and
BancorpSouth:

                  (a) by mutual consent of the Company and BancorpSouth in a
written instrument, if the Board of Directors of each so determines by a vote of
a majority of the members of its entire Board;

                  (b) By either BancorpSouth or the Company upon written notice
to the other party (i) 60 days after the date on which any request or
application for a Requisite Regulatory Approval shall have been denied or
withdrawn at the request or recommendation of the Governmental Entity which must
grant such Requisite Regulatory Approval, unless within the 60-day period
following such denial or withdrawal a petition for rehearing or an amended
application has been filed with the applicable Governmental Entity, provided,
however, that no party shall have the right to terminate this Agreement pursuant
to this Section 9.1(b)(i) if such denial or request or recommendation for
withdrawal shall be due to the failure of the party seeking to terminate this
Agreement to perform or observe the covenants and agreements of such party set
forth herein or (ii) if any Governmental Entity of competent jurisdiction shall
have issued a final nonappealable order enjoining or otherwise prohibiting the
Merger;

                  (c) by either BancorpSouth or the Company if the Merger shall
not have been consummated on or before June 30, 1999 unless the failure of the
Closing to occur by such date shall be due to the failure of the party seeking
to terminate this Agreement to perform or observe the covenants and agreements
of such party set forth herein;

                  (d) by either BancorpSouth or the Company (provided that the
Company may not terminate if it is in material breach of any of its obligations
under Section 7.3) if any approval of the shareholders of the Company required
for the consummation of the Merger shall not have been obtained by reason of the
failure to obtain the required vote at a duly held meeting of such shareholders
or at any adjournment or postponement thereof;

                  (e) by either BancorpSouth or the Company (provided that the
terminating party is not then in material breach of any representation,
warranty, covenant or other agreement contained herein) if any of the
representations or warranties set forth in this Agreement on the part of the
other party shall be untrue or incorrect in any material respect, which is not
cured within thirty days following written notice to the party making such
representation, or which, by its nature, cannot be cured prior to the Closing;
provided, however, that neither party shall have the right to terminate this
Agreement pursuant to this Section 9.1(e) unless the representation or warranty,
together with all other representations and warranties that are untrue or
incorrect, would entitle the party receiving such representation not to
consummate the transactions contemplated hereby under Section 8.2(a) (in the
case of a representation or warranty by the Company) or Section 8.3(a) (in the
case of a representation or warranty by BancorpSouth);

                  (f) by either BancorpSouth or the Company (provided that the
terminating party is not then in material breach of any representation,
warranty, covenant or other agreement contained herein) if there shall have been
a material breach of any of the covenants or agreements set forth in this
Agreement on the part of the other party, which breach shall not have been cured






                                      A-34
<PAGE>   146

within thirty days following receipt by the breaching party of written notice of
such breach from the other party hereto, or which breach, by its nature, cannot
be cured prior to the Closing;

                  (g) by BancorpSouth, (i) if the condition set forth on Section
8.2(h) is not satisfied, (ii) if the Board of Directors of the Company shall
have failed to recommend in the Proxy Statement that the Company's shareholders
approve and adopt this Agreement, or shall have withdrawn, modified or changed
in a manner adverse to BancorpSouth its approval or recommendation of this
Agreement and the transactions contemplated hereby, or (iii) as provided in
Section 1.10 hereof;

         9.2. Effect of Termination. In the event of termination of this
Agreement by either BancorpSouth or the Company as provided in Section 9.1, this
Agreement shall forthwith become void and have no effect except (i) Sections
7.2(b), 9.2 and 10.3 shall survive any termination of this Agreement and (ii)
that notwithstanding anything to the contrary contained in this Agreement, no
party shall be relieved or released from any liabilities or damages arising out
of its breach of any provision of this Agreement, it being understood that a
failure to obtain the approvals referred to in Section 8.2(h) shall not
constitute a breach of this Agreement by BancorpSouth or BancorpSouth Bank.

         9.3. Amendment. Subject to compliance with applicable law, this
Agreement may be amended by the parties hereto, by action taken or authorized by
their respective Boards of Directors, at any time before or after approval of
the matters presented in connection with the Merger by the shareholders of the
Company; provided, however, that after any approval of the transactions
contemplated by this Agreement by the Company's shareholders, there may not be,
without further approval of such shareholders, any amendment of this Agreement
which reduces the amount or changes the form of the consideration to be
delivered to the Company shareholders hereunder other than as contemplated by
this Agreement. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

         9.4. Extension; Waiver. At any time prior to the Effective Time, each
of the parties hereto, by action taken or authorized by its Board of Directors,
may, to the extent legally allowed, (a) extend the time for the performance of
any of the obligations or other acts of the other party hereto, (b) waive any
inaccuracies in the representations and warranties of the other party contained
herein or in any document delivered pursuant hereto and (c) waive compliance
with any of the agreements or conditions of the other party contained herein.
Any agreement on the part of a party hereto to any such extension or waiver
shall be valid only if set forth in a written instrument signed on behalf of
such party, but such extension or waiver or failure to insist on strict
compliance with an obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.


                                    ARTICLE X
                               GENERAL PROVISIONS

Closing), and (iii) subject to the satisfaction of 10.1 (b) December 31, 1998

terms) shall survive the Effective Time, except for those covenants and
agreements contained herein and therein which by their terms apply in whole or
in part after the Effective Time.

delivered to the other parties, it being understood that all parties need not

         10.7. Entire Agreement. This Agreement (including the documents and the
instruments referred to herein) constitutes the entire agreement and supersedes

terms or were otherwise breached. It is accordingly agreed that the parties
shall be entitled to an injunction or injunctions to prevent breaches of Section

thereof in any court of the United States or any state having jurisdiction, this
being in addition to any other remedy to which they are entitled at law or in
equity.

         10.10. Severability. Any term or provision of this Agreement which is

provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

by this Agreement without the consent of the other party, which such consent
shall not be unreasonably withheld.

         10.12. Assignment; Third Party Beneficiaries. Neither this Agreement
nor any of the rights, interests or obligations hereunder shall be assigned by
any of the parties hereto (whether by operation of law or otherwise) without the
prior written consent of the other parties. Subject to the preceding sentence,

than the parties hereto any rights or remedies hereunder.

         are entitled to dissent and obtain payment for their shares.

corporation in writing of the name and address of each person on whose behalf he

held on his or her behalf only if:

         or she is the beneficial shareholder or over which he or she has power

Section 10-2B-13.28. Procedure if shareholder dissatisfied with corporation's
offer or failure to perform

         (a) A dissenter may notify the corporation in writing of his or her own
estimate of the fair value of his or her shares and amount of interest due, and
demand payment of his or her estimate, or reject the corporation's offer under
Section 10-2B-13.25 and demand payment of the fair value of his or her shares
and interest due, if:

                  (1) The dissenter believes that the amount offered under
         Section 10-2B-13.25 is less than the fair value of his or her shares or
         that the interest due is incorrectly calculated;

                  (2) The corporation fails to make an offer under Section
         10-2B-13.25 within 60 days after the date set for demanding payment; or

                  (3) The corporation, having failed to take the proposed
         action, does not release the transfer restrictions imposed on shares
         within 60 days after the date set for demanding payment.

         (b) A dissenter waives his or her right to demand payment under this
section unless he or she notifies the corporation of his or her demand in
writing under subsection (a) within 30 days after the corporation offered
payment for his or her shares.


Section 10-2B-13.30.  Commencement of proceedings

         (a) If a demand for payment under Section 10-2B-13.28 remains
unsettled, the corporation shall commence a proceeding within 60 days after
receiving the payment demand and petition the court to determine the fair value
of the shares and accrued interest. If the corporation does not commence the
proceeding within the 60 day period, it shall pay each dissenter whose demand
remains unsettled the amount demanded.

         (b) The corporation shall commence the proceeding in the circuit court
of the county where the corporation's principal office (or, if none in this
state, its registered office) is located. If the corporation is a foreign
corporation without a registered office in this state, it shall commence the
proceeding in the county in this state where the registered office of the
domestic corporation merged with or whose shares were acquired by the foreign
corporation was located.





                                      B-5
<PAGE>   155

         (c) The corporation shall make all dissenters (whether or not residents
of this state) whose demands remain unsettled parties to the proceeding as in an
action against their shares, and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided under the Alabama Rules of Civil Procedure.

         (d) After service is completed, the corporation shall deposit with the
clerk of the court an amount sufficient to pay unsettled claims of all
dissenters party to the action in an amount per share equal to its prior
estimate of fair value, plus accrued interest, under Section 10-2B-13.25.

         (e) The jurisdiction of the court in which the proceeding is commenced
under subsection (b) is plenary and exclusive. The court may appoint one or more
persons as appraisers to receive evidence and recommend decision on the question
of fair value. The appraisers have the powers described in the order appointing
them, or in any amendment to it. The dissenters are entitled to the same
discovery rights as parties in other civil proceedings.

         (f) Each dissenter made a party to the proceeding is entitled to
judgment for the amount the court finds to be the fair value of his or her
shares, plus accrued interest. If the court's determination as to the fair value
of a dissenter's shares, plus accrued interest, is higher than the amount
estimated by the corporation and deposited with the clerk of the court pursuant
to subsection (d), the corporation shall pay the excess to the dissenting
shareholder. If the court's determination as to fair value, plus accrued
interest, of a dissenter's shares is less than the amount estimated by the
corporation and deposited with the clerk of the court pursuant to subsection
(d), then the clerk shall return the balance of funds deposited, less any costs
under Section 10-2B-13.31, to the corporation.

         (g) Upon payment of the judgment, and surrender to the corporation of
the certificate or certificates representing the appraised shares, a dissenting
shareholder ceases to have any interest in the shares.


Section 10-2B-13.31.  Court costs and counsel fees

         (a) The court in an appraisal proceeding commenced under Section
10-2B-13.30 shall determine all costs of the proceeding, including compensation
and expenses of appraisers appointed by the court. The court shall assess the
costs against the corporation, except that the court may assess costs against
all or some of the dissenters, in amounts the court finds equitable, to the
extent the court finds the dissenters acted arbitrarily, vexatiously, or not in
good faith in demanding payment under Section 10-2B-13.28.

         (b) The court may also assess the reasonable fees and expenses of
counsel and experts for the respective parties, in amounts the court finds
equitable:

                  (1) Against the corporation and in favor of any or all
         dissenters if the court finds the corporation did not substantially
         comply with the requirements of Sections 10-2B-13.20 through
         10-2B-13.28; or

                  (2) Against either the corporation or a dissenter, in favor of
         any other party, if the court finds that the party against whom the
         fees and expenses are assessed acted arbitrarily, vexatiously, or not
         in good faith with respect to the rights provided by this chapter.

         (c) If the court finds that the services of counsel for any dissenter
were of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to these counsel reasonable fees to be paid out of the amounts
awarded the dissenters who were benefited.

Section 10-2B-13.32. Powers of corporation as to shares acquired pursuant to
payment

         Shares acquired by a corporation pursuant to payment of the agreed
value therefor or to payment of the judgment entered therefor, as in this
chapter provided, may be held and disposed of by such corporation as in the case
of other treasury shares, except that, in the case of a merger or share
exchange, they may be held and disposed of as the plan of merger or share
exchange may otherwise provide.

Board of Directors
The First Corporation
414 South Seventh Street
Opelika, Alabama   36803

Members of the Board:

   
You have requested an update to our oral opinion delivered on August 12, 1998
and written opinion as of October 30 as to the fairness, from a financial point
of view, to the holders of the outstanding shares of common stock of The First
Corporation, Opelika, Alabama ("First Corporation") of the Exchange Ratio in the
proposed merger between First Corporation and BancorpSouth, Inc., Tupelo,
Mississippi, ("Bancorp"). The shares will be exchanged pursuant to an Agreement
and Plan of Merger (the "Merger Agreement") dated August 12, 1998. Pursuant to
the Merger Agreement, Bancorp shall cause First Corporation to be merged with
and into Bancorp. In consideration of the merger, Bancorp has offered to
exchange $40,600,000 in shares of its common stock for the outstanding shares of
First Corporation common stock. The actual number of Bancorp shares to be
exchanged for each share of First Corporation stock may fluctuate between 7.7043
and 10.4235 as a result of changes in an average price for Bancorp stock as set
forth in the Merger Agreement.
    

Alex Sheshunoff & Co. Investment Banking ("Sheshunoff") is regularly engaged in
the valuation of securities in connection with mergers and acquisitions, private
placements, and valuations for estate, corporate and other purposes.

In connection with our opinion, we have, among other things:

         1.       Reviewed Call Report information as of December 1997 and June
                  30, 1998 for First Corporation;

         2.       Reviewed internal financial and other operating information
                  provided by First Corporation;

         3.       Conducted conversations with executive management regarding
                  recent and projected financial performance of First
                  Corporation;

         4.       Compared First Corporation's recent operating results with
                  those of certain other banks in the Southeast region of the
                  United States which have recently been acquired;

         5.       Compared First Corporation's recent operating results with
                  those of certain other banks in Alabama which have recently
                  been acquired;

         6.       Compared the pricing multiples for the value to be received by
                  the stockholders of First Corporation in the Merger to those
                  of certain other banks in Alabama which have recently been
                  acquired;






                                      C-1
<PAGE>   158

         7.       Compared the pricing multiples for the value to be received by
                  the stockholders of First Corporation in the Merger to those
                  of certain other banks in the Southeast region of the United
                  States which have recently been acquired;

         8.       Performed an affordability analysis based on the projections
                  of earnings, based upon management's assumptions, for the
                  combined entity subsequent to the Merger;

         9.       Reviewed the historical stock price and trading volume of
                  Bancorp common stock and the lack of any active market for the
                  common stock of First Corporation;

         10.      Compared Bancorp's financial characteristics with certain
                  other banking organizations located in the Southeast region of
                  the United States, and;

         11.      Performed such other analyses as we deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy
and completeness of the information provided to us by First Corporation for the
purposes of this opinion. In addition, where appropriate, we have relied upon
publicly available information that we believe to be reliable, accurate and
complete; however, we cannot guarantee the reliability, accuracy or completeness
of any such publicly available information We have not made an independent
evaluation of the assets or liabilities of First Corporation or Bancorp, nor
have we been furnished with any such appraisals. We did not visit Bancorp and
have relied upon publicly available financial information concerning Bancorp and
the market performance of its stock.

We are not experts in the evaluation of loan portfolios for the purposes of
assessing the adequacy of the allowance for losses and have assumed that such
allowances for each of the companies are in the aggregate, adequate to cover
such losses. We have assumed that both First Corporation and Bancorp have
received all required regulatory approvals necessary to consummate the Merger
without conditions that will materially impact the Merger.

Our opinion is necessarily based on economic, market and other conditions as in
effect on, and the information made available to us as of the date hereof.
Events occurring after the date hereof could materially affect the assumptions
used in preparing this opinion.

Our opinion is limited to the fairness, from a financial point of view, of the
Exchange Ratio contained in the Merger to the holders of First Corporation's
common stock. Moreover, this letter, and the opinion expressed herein, do not
constitute a recommendation to any shareholder as to any approval of the Merger
or the Merger Agreement. It is understood that this letter is for the
information of the Board of Directors of First Corporation and may not be used
for any other purpose without our prior written consent.

Based on the foregoing and such other matters we have deemed relevant, it is our
opinion, as of the date hereof, that the Exchange Ratio is fair, from a
financial point of view to the stockholders of First Corporation.

                                Very truly yours,

         THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO CERTAIN PROVISIONS
CONTAINED HEREIN AND TO RESALE RESTRICTIONS UNDER THE SECURITIES ACT OF 1933, AS
AMENDED

         STOCK OPTION AGREEMENT, dated as of August 12, 1998, between The First
Corporation, an Alabama corporation ("Issuer"), and BancorpSouth, Inc., a
Mississippi corporation ("Grantee").

                              W I T N E S S E T H:

         WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of
Merger of even date herewith (the "Merger Agreement"), which agreement has been
executed by the parties hereto immediately prior to this Stock Option Agreement
(the "Agreement"); and

         WHEREAS, as a condition to Grantee's entering into the Merger Agreement
and in consideration therefor, Issuer has agreed to grant Grantee the Option (as
hereinafter defined);

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements set forth herein and in the Merger Agreement, the
parties hereto agree as follows:

         1. (a) Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase, subject to the terms hereof, up to 47,822
fully paid and nonassessable shares of Issuer's Common Stock, $0.05 par value
("Common Stock"), at a price of $125.00 per share (the "Option Price");
provided, however, that in no event shall the number of shares of Common Stock
for which this Option is exercisable exceed 19.9% of the Issuer's issued and
outstanding shares of Common Stock without giving effect to any shares subject
to or issued pursuant to the Option. The number of shares of Common Stock that
may be received upon the exercise of the Option and the Option Price are subject
to adjustment as herein set forth. All shares of Common Stock shall be issued
from shares to which the preemptive rights granted by the Restated Articles of
Incorporation of the Issuer do not apply.

                  (b) In the event that any additional shares of Common Stock
are either (i) issued or otherwise become outstanding after the date of this
Agreement (other than pursuant to this Agreement) or (ii) redeemed, repurchased,
retired or otherwise cease to be outstanding after the date of the Agreement,
the number of shares of Common Stock subject to the Option shall be increased or
decreased, as appropriate, so that, after such issuance, such number equals
19.9% of the number of shares of Common Stock then issued and outstanding
without giving effect to any shares subject or issued pursuant to the Option.
Nothing contained in this Section 1(b) or elsewhere in this Agreement shall be
deemed to authorize Issuer or Grantee to breach any provision of the Merger
Agreement.

         2. (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, and from time to time, if, but only if, both an Initial
Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as
hereinafter defined) shall have occurred prior to the occurrence of an Exercise
Termination Event (as hereinafter defined), provided that the Holder shall have
sent the written notice of such exercise (as provided in subsection (e) of this
Section 2) within 90 days following such Subsequent Triggering Event. Each of
the following shall be an "Exercise Termination Event": (i) the Effective Time
(as defined in the Merger Agreement) of the Merger; (ii) termination of the
Merger Agreement in accordance with the provisions thereof if such termination
occurs prior to the occurrence of an Initial Triggering Event except a
termination by Grantee pursuant to Section 9.1(f) of the Merger Agreement
(unless the breach by Issuer giving rise to such 





                                      D-1
<PAGE>   160

right of termination is non-volitional) or Section 9.1(g) of the Merger
Agreement; or (iii) the passage of 12 months after termination of the Merger
Agreement if such termination follows the occurrence of an Initial Triggering
Event or is a termination by Grantee pursuant to Section 9.1(f) of the Merger
Agreement (unless the breach by Issuer giving rise to such right of termination
is non-volitional) or Section 9.1(g) of the Merger Agreement. The term "Holder"
shall mean the Grantee or any future holder or holders of the Option.

                  (b) The term "Initial Triggering Event" shall mean any of the
following events or transactions occurring after the date hereof:

                           (i) Issuer or any of its Subsidiaries (each an
                  "Issuer Subsidiary"), without having received Grantee's prior
                  written consent, shall have entered into an agreement to
                  engage in an Acquisition Transaction (as hereinafter defined)
                  with any person (the term "person" for purposes of this
                  Agreement having the meaning assigned thereto in Sections
                  3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934,
                  as amended (the "1934 Act"), and the rules and regulations
                  thereunder) other than Grantee or any of its Subsidiaries
                  (each a "Grantee Subsidiary") or the Board of Directors of
                  Issuer shall have recommended that the shareholders of Issuer
                  approve or accept any Acquisition Transaction. For purposes of
                  this Agreement, "Acquisition Transaction" shall mean with
                  respect to any person except Grantee or any Grantee subsidiary
                  (w) a merger or consolidation, or any similar transaction,
                  involving Issuer or any Significant Subsidiary (as defined in
                  Rule 1-02 of Regulation S-X promulgated by the Securities and
                  Exchange Commission (the "SEC")) of Issuer, (x) a purchase,
                  lease or other acquisition or assumption of all or a
                  substantial portion of the assets or deposits of Issuer or any
                  Significant Subsidiary of Issuer, (y) a purchase or other
                  acquisition (including by way of merger, consolidation, share
                  exchange or otherwise) of securities representing 10% or more
                  of the voting power of Issuer, or (z) any substantially
                  similar transaction;

                           (ii) Issuer or any Issuer Subsidiary, without having
                  received Grantee's prior written consent, shall have
                  authorized, recommended, proposed or publicly announced its
                  intention to authorize, recommend or propose, to engage in an
                  Acquisition Transaction with any person other than Grantee or
                  a Grantee Subsidiary, or the Board of Directors of Issuer
                  shall have publicly withdrawn or modified, or publicly
                  announced its intention to withdraw or modify, in any manner
                  adverse to Grantee, its recommendation that the shareholders
                  of Issuer approve the transactions contemplated by the Merger
                  Agreement in anticipation of engaging in an Acquisition
                  Transaction;

                           (iii) Any person other than Grantee, any Grantee
                  Subsidiary or any Issuer Subsidiary acting in a fiduciary
                  capacity in the ordinary course of its business shall have
                  acquired beneficial ownership or the right to acquire
                  beneficial ownership of 10% or more of the outstanding shares
                  of Common Stock (the term "beneficial ownership" for purposes
                  of this Agreement having the meaning assigned thereto in
                  Section 13(d) of the 1934 Act, and the rules and regulations
                  thereunder);

                           (iv) Any person other than Grantee or any Grantee
                  Subsidiary shall have made a bona fide proposal to Issuer or
                  its shareholders by public announcement or written
                  communication that is or becomes the subject of public
                  disclosure to engage in an Acquisition Transaction;

                           (v) After an overture is made by a third party to
                  Issuer or its shareholders to engage in an Acquisition
                  Transaction, Issuer shall have breached any covenant or
                  obligation contained in the Merger Agreement and such breach
                  (x) would 




                                      D-2
<PAGE>   161

                  entitle Grantee to terminate the Merger Agreement and (y)
                  shall not have been cured prior to the Notice Date (as defined
                  below); or

                           (vi) Any person other than Grantee or any Grantee
                  Subsidiary, other than in connection with a transaction to
                  which Grantee has given its prior written consent, shall have
                  filed an application or notice with the Federal Reserve Board,
                  or other federal or state bank regulatory authority, which
                  application or notice has been accepted for processing, for
                  approval to engage in an Acquisition Transaction.

                  (c) The term "Subsequent Triggering Event" shall mean either
of the following events or transactions occurring after the date hereof:

                           (i) The acquisition by any person of beneficial
                  ownership of 25% or more of the then outstanding Common Stock;
                  or

                           (ii) The occurrence of the Initial Triggering Event
                  described in paragraph (i) of subsection (b) of this Section
                  2, except that the percentage referred to in clause (y) shall
                  be 25%.

                  (d) Issuer shall notify Grantee promptly in writing of the
occurrence of any Initial Triggering Event or Subsequent Triggering Event of
which it has notice (together, a "Triggering Event"), it being understood that
the giving of such notice by Issuer shall not be a condition to the right of the
Holder to exercise the Option.

                  (e) In the event the Holder is entitled to and wishes to
exercise the Option, it shall send to Issuer a written notice (the date of which
being herein referred to as the "Notice Date") specifying (i) the total number
of shares it will purchase pursuant to such exercise and (ii) a place and date
not earlier than three business days nor later than 60 business days from the
Notice Date for the closing of such purchase (the "Closing Date"); provided that
if prior notification to or approval of the Federal Reserve Board or any other
regulatory agency is required in connection with such purchase, the Holder shall
promptly file the required notice or application for approval and shall
expeditiously process the same and the period of time that otherwise would run
pursuant to this sentence shall run instead from the date on which any required
notification periods have expired or been terminated or such approvals have been
obtained and any requisite waiting period or periods shall have passed. Any
exercise of the Option shall be deemed to occur on the Notice Date relating
thereto.

                  (f) At the closing referred to in subsection (e) of this
Section 2, the Holder shall pay to Issuer the aggregate purchase price for the
shares of Common Stock purchased pursuant to the exercise of the Option in
immediately available funds by wire transfer to a bank account designated by
Issuer, provided that failure or refusal of Issuer to designate such a bank
account shall not preclude the Holder from exercising the Option.

                  (g) At such closing, simultaneously with the delivery of
immediately available funds as provided in subsection (f) of this Section 2,
Issuer shall deliver to the Holder a certificate or certificates representing
the number of shares of Common Stock purchased by the Holder and, if the Option
should be exercised in part only, a new Option evidencing the rights of the
Holder thereof to purchase the balance of the shares purchasable hereunder, and
the Holder shall deliver to Issuer this Agreement and a letter agreeing that the
Holder will not offer to sell or otherwise dispose of such shares in violation
of applicable law or the provisions of this Agreement.

                  (h) Certificates for Common Stock delivered at a closing
hereunder may be endorsed with a restrictive legend that shall read
substantially as follows:





                                      D-3
<PAGE>   162

                           "The transfer of the shares represented by this
                  certificate is subject to certain provisions of an agreement
                  between the registered holder hereof and Issuer and to resale
                  restrictions arising under the Securities Act of 1933, as
                  amended. A copy of such agreement is on file at the principal
                  office of Issuer and will be provided to the holder hereof
                  without charge upon receipt by Issuer of a written request
                  therefor."

                  It is understood and agreed that: (i) the reference to the
resale restrictions of the Securities Act of 1933, as amended (the "1933 Act"),
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the Holder shall have delivered to Issuer a copy of a
letter from the staff of the SEC, or an opinion of counsel, in form and
substance reasonably satisfactory to Issuer, to the effect that such legend is
not required for purposes of the 1933 Act; (ii) the reference to the provisions
to this Agreement in the above legend shall be removed by delivery of substitute
certificate(s) without such reference if the shares have been sold or
transferred in compliance with the provisions of this Agreement and under
circumstances that do not require the retention of such reference; and (iii) the
legend shall be removed in its entirety if the conditions in the preceding
clauses (i) and (ii) are both satisfied. In addition, such certificates shall
bear any other legend as may be required by law.

                  (i) Upon the giving by the Holder to Issuer of the written
notice of exercise of the Option provided for under subsection (e) of this
Section 2 and the tender of the applicable purchase price in immediately
available funds, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that the
stock transfer books of Issuer shall then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
the Holder. Issuer shall pay all expenses, and any and all United States
federal, state and local taxes and other charges that may be payable in
connection with the preparation, issue and delivery of stock certificates under
this Section 2 in the name of the Holder or its assignee, transferee or
designee.

         3. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued shares of Common Stock so
that the Option may be exercised without additional authorization of Common
Stock after giving effect to all other options, warrants, convertible securities
and other rights to purchase Common Stock; (ii) that it will not, by charter
amendment or through reorganization, consolidation, merger, dissolution or sale
of assets, or by any other voluntary act, avoid or seek to avoid the observance
or performance of any of the covenants, stipulations or conditions to be
observed or performed hereunder by Issuer; (iii) promptly to take all action as
may from time to time be required (including (x) complying with all premerger
notification, reporting and waiting period requirements specified in 15 U.S.C.
ss.ss. 18a and regulations promulgated thereunder and (y) in the event, under
the Bank Holding Company Act of 1956, as amended (the "BHCA"), or the Change in
Bank Control Act of 1978, as amended, or any state banking law, prior approval
of or notice to the Federal Reserve Board or to any state regulatory authority
is necessary before the Option may be exercised, cooperating fully with the
Holder in preparing such applications or notices and providing such information
to the Federal Reserve Board or such state regulatory authority as they may
require) in order to permit the Holder to exercise the Option and Issuer duly
and effectively to issue shares of Common Stock pursuant hereto; and (iv)
promptly to take all action provided herein to protect the rights of the Holder
against dilution.

         4. This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock purchasable hereunder.
The terms "Agreement" and "Option" as used herein include any Stock Option
Agreements and related Options for which this Agreement (and the Option granted
hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this





                                      D-4
<PAGE>   163

Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

         5. In addition to the adjustment in the number of shares of Common
Stock that are purchasable upon exercise of the Option pursuant to Section 1 of
this Agreement, the number of shares of Common Stock purchasable upon the
exercise of the Option and the Option Price shall be subject to adjustment from
time to time as provided in this Section 5. In the event of any change in, or
distributions in respect of, the Common Stock by reason of stock dividends,
split-ups, mergers, recapitalizations, combinations, subdivisions, conversions,
exchanges of shares, distributions on or in respect of the Common Stock that
would be prohibited under the terms of the Merger Agreement, or the like, the
type and number of shares of Common Stock purchasable upon exercise hereof and
the Option Price shall be appropriately adjusted in such manner as shall fully
preserve the economic benefits provided hereunder and proper provision shall be
made in any agreement governing any such transaction to provide for such proper
adjustment and the full satisfaction of the Issuer's obligations hereunder.

         6. Upon the occurrence of a Subsequent Triggering Event that occurs
prior to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within 90 days of such Subsequent Triggering Event (whether on its own
behalf or on behalf of any subsequent holder of this Option (or part thereof) or
any of the shares of Common Stock issued pursuant hereto), promptly prepare,
file and keep current a shelf registration statement under the 1933 Act covering
this Option and any shares issued and issuable pursuant to this Option and shall
use its reasonable best efforts to cause such registration statement to become
effective and remain current in order to permit the sale or other disposition of
this Option and any shares of Common Stock issued upon total or partial exercise
of this Option ("Option Shares") in accordance with any plan of disposition
requested by Grantee. Issuer will use its reasonable best efforts to cause such
registration statement first to become effective and then to remain effective
for such period not in excess of 180 days from the day such registration
statement first becomes effective or such shorter time as may be reasonably
necessary to effect such sales or other dispositions. Grantee shall have the
right to demand two such registrations. The foregoing notwithstanding, if, at
the time of any request by Grantee for registration of the Option or Option
Shares as provided above, Issuer is in registration with respect to an
underwritten public offering of shares of Common Stock, and if in the good faith
judgment of the managing underwriter or managing underwriters, or, if none, the
sole underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
provided, however, that after any such required reduction the number of Option
Shares to be included in such offering for the account of the Holder shall
constitute at least 25% of the total number of shares to be sold by the Holder
and Issuer in the aggregate; and provided further, however, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance as promptly as practicable and no reduction shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating itself in respect of representations,
warranties, indemnities and other agreements customarily included in secondary
offering underwriting agreements for the Issuer. Upon receiving any request
under this Section 6 from any Holder, Issuer agrees to send a copy thereof to
any other person known to Issuer to be entitled to registration rights under
this Section 6, in each case by promptly mailing the same, postage prepaid, to
the address of record of the persons entitled to receive such copies.
Notwithstanding anything to the contrary contained herein, in no event shall
Issuer be obligated to effect more than two registrations pursuant to this
Section 6 by 





                                      D-5
<PAGE>   164

reason of the fact that there shall be more than one Grantee as a result of any
assignment or division of this Agreement.

         7. (a) Immediately prior to the occurrence of a Repurchase Event (as
defined below), (i) following a request of the Holder, delivered prior to an
Exercise Termination Event, Issuer (or any successor thereto) shall repurchase
the Option from the Holder at a price (the "Option Repurchase Price") equal to
the amount by which (A) the Market/Offer Price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised and (ii) at the request of the owner of Option Shares from
time to time (the "Owner"), delivered within 90 days of such occurrence (or such
later period as provided in Section 10), Issuer shall repurchase such number of
the Option Shares from the Owner as the Owner shall designate at a price (the
"Option Share Repurchase Price") equal to the Market/Offer Price multiplied by
the number of Option Shares so designated. The term "Market/Offer Price" shall
mean the highest of (i) the price per share of Common Stock at which a tender
offer or exchange offer therefor has been made, (ii) the price per share of
Common Stock to be paid by any third party pursuant to an agreement with Issuer,
(iii) the highest closing price for shares of Common Stock within the six-month
period immediately preceding the date the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be, or (iv) in the event of a sale of all or a
substantial portion of Issuer's assets, the sum of the price paid in such sale
for such assets and the current market value of the remaining assets of Issuer
as determined by a nationally recognized investment banking firm selected by the
Holder or the Owner, as the case may be, and reasonably acceptable to the
Issuer, divided by the number of shares of Common Stock of Issuer outstanding at
the time of such sale. In determining the Market/Offer Price, the value of
consideration other than cash shall be determined by a nationally recognized
investment banking firm selected by the Holder or Owner, as the case may be, and
reasonably acceptable to the Issuer.

                  (b) The Holder and the Owner, as the case may be, may exercise
its right to require Issuer to repurchase the Option and any Option Shares
pursuant to this Section 7 by surrendering for such purpose to Issuer, at its
principal office, this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. Within the latter to occur of (x) five business days after the
surrender of the Option and/or certificates representing Option Shares and the
receipt of such notice or notices relating thereto and (y) the time that is
immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver
or cause to be delivered to the Holder the Option Repurchase Price and/or to the
Owner the Option Share Repurchase Price therefor or the portion thereof, if any,
that Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that Issuer is prohibited under applicable
law or regulation from repurchasing the Option and/or the Option Shares in full,
Issuer shall immediately so notify the Holder and/or the Owner and thereafter
deliver or cause to be delivered, from time to time, to the Holder and/or the
Owner, as appropriate, the portion of the Option Repurchase Price and the Option
Share Repurchase Price, respectively, that it is no longer prohibited from
delivering, within five business days after the date on which Issuer is no
longer so prohibited; provided, however, that if Issuer at any time after
delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7
is prohibited under applicable law or regulation from delivering to the Holder
and/or the Owner, as appropriate, the Option 





                                      D-6

Repurchase Price and the Option Share Repurchase Price, respectively, in full
(and Issuer hereby undertakes to use its best efforts to obtain all required
regulatory and legal approvals and to file any required notices as promptly as
practicable in order to accomplish such repurchase), the Holder or Owner may
revoke its notice of repurchase of the Option or the Option Shares either in
whole or to the extent of the prohibition, whereupon, in the latter case, Issuer
shall promptly (i) deliver to the Holder and/or the Owner, as appropriate, that
portion of the Option Repurchase Price or the Option Share Repurchase Price that
Issuer is not prohibited from delivering; and (ii) deliver, as appropriate,
either (A) to the Holder, a new Stock Option Agreement evidencing the right of
the Holder to purchase that number of shares of Common Stock obtained by
multiplying the number of shares of Common Stock for which the surrendered Stock
Option Agreement was exercisable at the time of delivery of the notice of
repurchase by a fraction, the numerator of which is the Option Repurchase Price
less the portion thereof theretofore delivered to the Holder and the denominator
of which is the Option Repurchase Price, or (B) to the Owner, a certificate for
the Option Shares it is then so prohibited from repurchasing

                  (d) For purposes of this Section 7, a Repurchase Event shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving Issuer or any purchase, lease or
other acquisition of all or a substantial portion of the assets of Issuer, other
than any such transaction which would not constitute an Acquisition Transaction
pursuant to the provisos to Section 2(b)(i) hereof or (ii) upon the acquisition
by any person of beneficial ownership of 50% or more of the then outstanding
shares of Common Stock, provided that no such event shall constitute a
Repurchase Event unless a Subsequent Triggering Event shall have occurred prior
to an Exercise Termination Event. The parties hereto agree that Issuer's
obligations to repurchase the Option or Option Shares under this Section 7 shall
not terminate upon the occurrence of an Exercise Termination Event unless no
Subsequent Triggering Event shall have occurred prior to the occurrence of an
Exercise Termination Event.

         8. (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or one of its Subsidiaries, and shall not be the continuing
or surviving corporation of such consolidation or merger, (ii) to permit any
person, other than Grantee or one of its Subsidiaries, to merge into Issuer and
Issuer shall be the continuing or surviving corporation, but, in connection with
such merger, the then outstanding shares of Common Stock shall be changed into
or exchanged for stock or other securities of any other person or cash or any
other property or the then outstanding shares of Common Stock shall after such
merger represent less than 50% of the outstanding voting shares and voting share
equivalents of the merged company, or (iii) to sell or otherwise transfer all or
substantially all of its assets to any person, other than Grantee or one of its
Subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provision so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
Option"), at the election of the Holder, of either (x) the Acquiring Corporation
(as hereinafter defined) or (y) any person that controls the Acquiring
Corporation.

                  (b)      The following terms have the meanings indicated:

                           (1) "Acquiring Corporation" shall mean (i) the
                  continuing or surviving corporation of a consolidation or
                  merger with Issuer (if other than Issuer), (ii) Issuer in a
                  merger in which Issuer is the continuing or surviving person,
                  and (iii) the transferee of all or substantially all of
                  Issuer's assets.

                           (2) "Substitute Common Stock" shall mean the common
                  stock issued by the issuer of the Substitute Option upon
                  exercise of the Substitute Option.

                           (3) "Assigned Value" shall mean the Market/Offer
                  Price, as defined in Section 7.

                           (4) "Average Price" shall mean the average closing
                  price of a share of the Substitute Common Stock for the one
                  year immediately preceding the consolidation, merger or sale
                  in question, but in no event higher than the closing price of
                  the shares of Substitute Common Stock on the day preceding
                  such consolidation, merger or sale; 





                                      D-7
<PAGE>   166

                  provided that if Issuer is the issuer of the Substitute
                  Option, the Average Price shall be computed with respect to a
                  share of common stock issued by the person merging into Issuer
                  or by any company which controls or is controlled by such
                  person, as the Holder may elect.

                  (c) The Substitute Option shall have the same terms as the
Option, provided, that if the terms of the Substitute Option cannot, for legal
reasons, be the same as the Option, such terms shall be as similar as possible
and in no event less advantageous to the Holder. The issuer of the Substitute
Option shall also enter into an agreement with the then Holder or Holders of the
Substitute Option in substantially the same form as this Agreement, which shall
be applicable to the Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of Substitute Common Stock as is equal to the Assigned Value
multiplied by the number of shares of Common Stock for which the Option is then
exercisable, divided by the Average Price. The exercise price of the Substitute
Option per share of Substitute Common Stock shall then be equal to the Option
Price multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock for which the Option is then exercisable and the
denominator of which shall be the number of shares of Substitute Common Stock
for which the Substitute Option is exercisable.

                  (e) In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the shares of
Substitute Common Stock outstanding prior to exercise of the Substitute Option.
In the event that the Substitute Option would be exercisable for more than 19.9%
of the shares of Substitute Common Stock outstanding prior to exercise but for
this clause (e), the issuer of the Substitute Option (the "Substitute Option
Issuer") shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in this
clause (e) over (ii) the value of the Substitute Option after giving effect to
the limitation in this clause (e). This difference in value shall be determined
by a nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be, and reasonably acceptable to the Acquiring
Corporation.

                  (f) Issuer shall not enter into any transaction described in
subsection (a) of this Section 8 unless the Acquiring Corporation and any person
that controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

         9. (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder"), the Substitute Option Issuer shall repurchase the
Substitute Option from the Substitute Option Holder at a price (the "Substitute
Option Repurchase Price") equal to the amount by which (i) the Highest Closing
Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute
Option, multiplied by the number of shares of Substitute Common Stock for which
the Substitute Option may then be exercised and at the request of the owner (the
"Substitute Share Owner") of shares of Substitute Common Stock (the "Substitute
Shares"), the Substitute Option Issuer shall repurchase the Substitute Shares at
a price (the "Substitute Share Repurchase Price") equal to the Highest Closing
Price multiplied by the number of Substitute Shares so designated. The term
"Highest Closing Price" shall mean the highest closing price for shares of
Substitute Common Stock within the six-month period immediately preceding the
date the Substitute Option Holder gives notice of the required repurchase of the
Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.

                  (b) The Substitute Option Holder and the Substitute Share
Owner, as the case may be, may exercise its respective right to require the
Substitute Option Issuer to repurchase the Substitute Option and the Substitute
Shares pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal office, the agreement for such
Substitute Option (or, in the absence of such an agreement, a copy of this
Agreement) and certificates for 




                                      D-8
<PAGE>   167

Substitute Shares accompanied by a written notice or notices stating that the
Substitute Option Holder or the Substitute Share Owner, as the case may be,
elects to require the Substitute Option Issuer to repurchase the Substitute
Option and/or the Substitute Shares in accordance with the provisions of this
Section 9. As promptly as practicable, and in any event within five business
days after the surrender of the Substitute Option and/or certificates
representing Substitute Shares and the receipt of such notice or notices
relating thereto, the Substitute Option Issuer shall deliver or cause to be
delivered to the Substitute Option Holder the Substitute Option Repurchase Price
and/or to the Substitute Share Owner the Substitute Share Repurchase Price
therefor or, in either case, the portion thereof which the Substitute Option
Issuer is not then prohibited under applicable law and regulation from so
delivering.

                  (c) To the extent that the Substitute Option Issuer is
prohibited under applicable law or regulation from repurchasing the Substitute
Option and/or the Substitute Shares in part or in full, the Substitute Option
Issuer following a request for repurchase pursuant to this Section 9 shall
immediately so notify the Substitute Option Holder and/or the Substitute Share
Owner and thereafter deliver or cause to be delivered, from time to time, to the
Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the
portion of the Substitute Share Repurchase Price, respectively, which it is no
longer prohibited from delivering, within five business days after the date on
which the Substitute Option Issuer is no longer so prohibited; provided,
however, that if the Substitute Option Issuer is at any time after delivery of a
notice of repurchase pursuant to subsection (b) of this Section 9 prohibited
under applicable law or regulation from delivering to the Substitute Option
Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option
Repurchase Price and the Substitute Share Repurchase Price, respectively, in
full (and the Substitute Option Issuer shall use its best efforts to obtain all
required regulatory and legal approvals as promptly as practicable in order to
accomplish such repurchase), the Substitute Option Holder or Substitute Share
Owner may revoke its notice of repurchase of the Substitute Option or the
Substitute Shares either in whole or to the extent of the prohibition,
whereupon, in the latter case, the Substitute Option Issuer shall promptly (i)
deliver to the Substitute Option Holder or Substitute Share Owner, as
appropriate, that portion of the Substitute Option Repurchase Price or the
Substitute Share Repurchase Price that the Substitute Option Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the
Substitute Option Holder, a new Substitute Option evidencing the right of the
Substitute Option Holder to purchase that number of shares of the Substitute
Common Stock obtained by multiplying the number of shares of the Substitute
Common Stock for which the surrendered Substitute Option was exercisable at the
time of delivery of the notice of repurchase by a fraction, the numerator of
which is the Substitute Option Repurchase Price less the portion thereof
theretofore delivered to the Substitute Option Holder and the denominator of
which is the Substitute Option Repurchase Price, or (B) to the Substitute Share
Owner, a certificate for the Substitute Common Shares it is then so prohibited
from repurchasing.

         10. The 90-day period for exercise of certain rights under Sections 2,
6, 7 and 13 shall be extended: (i) to the extent necessary to obtain all
regulatory approvals for the exercise of such rights and for the expiration of
all statutory waiting periods; and (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise.

         11. Issuer hereby represents and warrants to Grantee as follows:

                  (a) Issuer has full corporate power and authority to execute
and deliver this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of Issuer and no other corporate proceedings on the part of
Issuer are necessary to authorize this Agreement or to consummate the
transactions so contemplated. This Agreement has been duly and validly executed
and delivered by Issuer and is enforceable against Issuer in accordance with its
terms.






                                      D-9
<PAGE>   168

                  (b) Issuer has taken all necessary corporate action to
authorize and reserve and to permit it to issue, and at all times from the date
hereof through the termination of this Agreement in accordance with its terms
will have reserved for issuance upon the exercise of the Option, that number of
shares of Common Stock equal to the maximum number of shares of Common Stock at
any time and from time to time issuable hereunder, and all such shares, upon
issuance pursuant hereto, will be duly authorized, validly issued, fully paid,
nonassessable, and will be delivered free and clear of all claims, liens,
encumbrance and security interests and not subject to any preemptive rights.

         12. Grantee hereby represents and warrants to Issuer that:

                  (a) Grantee has all requisite corporate power and authority to
enter into this Agreement and, subject to any approvals or consents referred to
herein, to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary corporate action on the part
of Grantee. This Agreement has been duly executed and delivered by Grantee.

                  (b) The Option is not being, and any shares of Common Stock or
other securities acquired by Grantee upon exercise of the Option will not be,
acquired with a view to the public distribution thereof and will not be
transferred or otherwise disposed of except in a transaction registered or
exempt from registration under the 1933 Act.

         13. Neither of the parties hereto may assign any of its rights or
obligations under this Option Agreement or the Option created hereunder to any
other person, without the express written consent of the other party, except
that in the event a Subsequent Triggering Event shall have occurred prior to an
Exercise Termination Event, Grantee, subject to the express provisions hereof,
may assign in whole or in part its rights and obligations hereunder within 90
days following such Subsequent Triggering Event (or such later period as
provided in Section 10); provided, however, that until the date 15 days
following the date on which the Federal Reserve Board approves an application by
Grantee under the BHCA to acquire the shares of Common Stock subject to the
Option, Grantee may not assign its rights under the Option except in (i) a
widely dispersed public distribution, (ii) a private placement in which no one
party acquires the right to purchase in excess of 2% of the voting shares of
Issuer, (iii) an assignment to a single party (e.g., a broker or investment
banker) for the purpose of conducting a widely dispersed public distribution on
Grantee's behalf, or (iv) any other manner approved by the Federal Reserve
Board.

         14. Each of Grantee and Issuer will use its best efforts to make all
filings with, and to obtain consents of, all third parties and governmental
authorities necessary to the consummation of the transactions contemplated by
this Agreement, including without limitation making application to authorize for
quotation the shares of Common Stock issuable hereunder on any exchange or
market on which the shares of Issuer may be listed upon official notice of
issuance and applying to the Federal Reserve Board under the BHCA for approval
to acquire the shares issuable hereunder, but Grantee shall not be obligated to
apply to state banking authorities for approval to acquire the shares of Common
Stock issuable hereunder until such time, if ever, as it deems appropriate to do
so.

         15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief.

         16. If any term, provision, covenant or restriction contained in this
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or 





                                      D-10
<PAGE>   169

invalidated. If for any reason such court or regulatory agency determines that
the Holder is not permitted to acquire, or Issuer is not permitted to repurchase
pursuant to Section 7, the full number of shares of Common Stock provided in
Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5 hereof), it is
the express intention of Issuer to allow the Holder to acquire or to require
Issuer to repurchase such lesser number of shares as may be permissible, without
any amendment or modification hereof.

         17. All notices, requests, claims, demands and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
cable, telegram, telecopy or telex, or by registered or certified mail (postage
prepaid, return receipt requested) at the respective addresses of the parties
set forth in the Merger Agreement.

         18. This Agreement shall be governed by and construed in accordance
with the laws of the State of Mississippi, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

         19. This Agreement may be executed in two counterparts, each of which
shall be deemed to be an original, but all of which shall constitute one and the
same agreement.

         20. Except as otherwise expressly provided herein, each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions contemplated hereunder, including fees and
expenses of its own financial consultants, investment bankers, accountants and
counsel.

         21. Except as otherwise expressly provided herein or in the Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof, written or oral. The terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assigns.
Nothing in this Agreement, expressed or implied, is intended to confer upon any
party, other than the parties hereto, and their respective successors and
permitted assigns, any rights, remedies, obligations or liabilities under or by
reason of this Agreement, except as expressly provided herein.

         22. Capitalized terms used in this Agreement and not defined herein
shall have the meanings assigned thereto in the Merger Agreement.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         A.    RESTATED ARTICLES OF INCORPORATION AND BYLAWS.

         The Registrant's Restated Articles of Incorporation provide that it
will indemnify, and upon request advance expenses to, any person (or his estate)
who was or is a party to any legal proceeding because he is or was a director,
officer or employee of BancorpSouth, or is or was serving at the request of
BancorpSouth as a director, officer, partner, trustee, employee or agent of
another corporation, partnership, or other entity, against any liability
incurred in that proceeding (A) to the full extent permitted by the MBCA, and
(B) despite the fact that such person did not meet the standard of conduct
specified in the MBCA or would be disqualified for indemnification under the
MBCA, if a determination is made that (i) the person seeking indemnity is fairly
and reasonably entitled to indemnification in view of all of the relevant
circumstances, and (ii) his acts or omissions did not constitute gross
negligence or willful misconduct. A request for reimbursement or advancement of
expenses prior to final disposition of the proceeding must be accompanied by an
undertaking to repay the advances if it is ultimately determined that he did not
meet the requisite standard of conduct but it need not be accompanied by an
affirmation that the person seeking indemnity believed he has met the standard
of conduct.

         The Registrant's Bylaws provide that it will indemnify officers and
directors who are a party to any legal proceeding because he is or was an
officer or director of BancorpSouth against any expenses or awards in connection
therewith if he acted in good faith and in a manner he reasonably believed to be
in the best interest of BancorpSouth and, with respect to any criminal
proceeding, had no reasonable cause to believe his conduct was unlawful. The
Registrant also will indemnify officers and directors who are a party to any
derivative suit with respect to the Registrant because that person is or was an
officer or director of the Registrant, against expenses incurred in connection
with that action unless he is found to have acted without good faith and without
that degree of care, diligence and skill which ordinarily prudent men would
exercise in similar circumstances and in like positions, unless, despite such
finding of liability, the court determines that he is entitled to indemnity. The
Bylaws also provide that the Registrant may (i) advance to the officer or
director the expenses incurred in defending a proceeding upon receipt of an
undertaking that he will repay amounts advanced unless it ultimately is
determined that he is entitled to be indemnified, and (ii) purchase and maintain
insurance on behalf of an officer or director against any liability arising out
of his acting as such.

         B.    Mississippi Business Corporation Act.

         In addition to the foregoing provisions of the Registrant's Restated
Articles of Incorporation and Bylaws, directors, officers, employees and agents
of the Registrant and its subsidiaries may be indemnified by the Registrant
pursuant to Sections 79-4-8.50 through 79-4-8.58 of the MBCA.

         C.    Insurance.

         The Registrant maintains and pays premiums on an insurance policy on
behalf of its officers and directors against liability asserted against or
incurred by such persons in or arising from their capacity as such.

<PAGE>   172

         D.    SEC Policy On Indemnification.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the SEC such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 22. UNDERTAKINGS.

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the Registration
                           Statement (or the most recent post-effective 
                           amendment




                                      II-2
<PAGE>   173
                           thereof) which, individually or in the aggregate,
                           represent a fundamental change in the information set
                           forth in the Registration Statement. Notwithstanding
                           the foregoing, any increase or decrease in volume of
                           securities offered (if the total dollar value of
                           securities offered would not exceed that which was
                           registered) and any deviation from the low or high
                           end of the estimated maximum offering range may be
                           reflected in the form of prospectus filed with the
                           SEC pursuant to Rule 424(b) if, in the aggregate, the
                           changes in volume and price represent no more than a
                           20% change in the maximum aggregate offering price
                           set forth in the "Calculation of Registration Fee"
                           table in the effective Registration Statement.

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the Registration Statement or any material change to
                           such information in the Registration Statement.

         (2) For the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange
Act) that is incorporated by reference in the Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

         The Registrant undertakes that every prospectus: (i) that is filed
pursuant to the paragraph immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant, pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted against the
Registrant by such 





                                      II-3
<PAGE>   174

director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

         The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.

         The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
