Dear Shareholder:

   
     You are cordially invited to attend a special meeting of shareholders of
LaPlace Bancshares, Inc. to be held at 5:30 PM, local time, on December 30,
1998 at the office of Bank of LaPlace of St. John the Baptist Parish, Louisiana,
110 Belle Terre Blvd., LaPlace, Louisiana.

     At the special meeting, you will be asked to vote on a proposal to approve
a merger agreement between LaPlace, Union Planters Holding Corporation, a
subsidiary of Union Planters Corporation and Union Planters Corporation. The
merger agreement provides for the merger of LaPlace and Union Planters Holding
Corporation, a wholly-owned subsidiary of Union Planters. As a result of the
merger, each outstanding share of LaPlace common stock will be converted into
2.83 shares of Union Planters common stock. Cash (without interest) will be paid
in lieu of the issuance of fractional shares of Union Planters common stock. THE
ACCOMPANYING PROXY STATEMENT-PROSPECTUS CONTAINS DETAILED INFORMATION ABOUT THE
PROPOSED MERGER. YOU SHOULD READ IT CAREFULLY.

     The closing price of Union Planters common stock on the New York Stock
Exchange on November 27, 1998 was $48.9375. If the merger had been consummated
on that date the value of the Union Planters shares to be received for each
share of LaPlace common stock, based on the closing price of Union Planters
common stock on November 27, 1998, would have been $138.49.
    

     AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS UNANIMOUSLY APPROVED
THE AGREEMENT AND THE RELATED PLAN OF MERGER. THE BOARD BELIEVES THE MERGER IS
IN THE BEST INTERESTS OF LAPLACE AND ITS SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS
THAT YOU VOTE FOR APPROVAL OF THE AGREEMENT AND THE RELATED PLAN OF MERGER. THE
REASONS FOR THE BOARD OF DIRECTORS' RECOMMENDATION ARE STATED IN THE
ACCOMPANYING PROXY STATEMENT-PROSPECTUS. FURTHERMORE, LAPLACE'S FINANCIAL
ADVISOR, MERCER CAPITAL MANAGEMENT, INC., HAS ISSUED ITS OPINION TO THE EFFECT
THAT THE EXCHANGE RATIO OF UNION PLANTERS COMMON STOCK FOR LAPLACE COMMON STOCK
IN THE MERGER IS FAIR, FROM A FINANCIAL POINT OF VIEW, TO LAPLACE'S
SHAREHOLDERS.

     The merger presents an exceptional opportunity for holders of LaPlace
common stock to join on favorable terms in a combined enterprise with greater
financial resources and a more geographically diversified business. As a result
of the proposed merger, you, as a new shareholder of Union Planters, will own
common stock in a bank holding company whose shares are actively traded on the
New York Stock Exchange.

     We urge you to read the enclosed materials carefully so that you can
evaluate the merger for yourself.

     All shareholders are invited to attend the special meeting in person.
However, in order to ensure that your shares will be represented at the special
meeting, please date, sign and promptly return the enclosed proxy card in the
enclosed postage-paid envelope, whether or not you plan to attend the special
meeting. If you attend the special meeting in person, you may, if you wish, vote
personally on all matters brought before the special meeting.

                                    Very truly yours,



                                    Thomas W. Smith, Jr.
                                    President

                             YOUR VOTE IS IMPORTANT
                     PLEASE SIGN, DATE AND RETURN YOUR PROXY

     PROXY STATEMENT                    
 FOR THE SPECIAL MEETING                               PROSPECTUS
   OF SHAREHOLDERS OF                          UNION PLANTERS CORPORATION
LAPLACE BANCSHARES, INC.

   
                                MERGER PROPOSED

     Your board of directors has agreed on a transaction which will result in
the acquisition of LaPlace Bancshares, Inc. by Union Planters Corporation, a
multi-state bank holding company headquartered in Memphis, Tennessee by means of
the merger of LaPlace into a subsidiary of Union Planters. In the proposed
merger, Union Planters will issue shares of its common stock in exchange for
shares of LaPlace common stock. At the special meeting, we will ask you to
approve the merger agreement, which sets out the terms of the merger. We cannot
complete the merger unless you approve the merger agreement.


     If we complete the merger, you will receive 2.83 shares of Union Planters
common stock for each of your shares of LaPlace common stock. If the exchange
results in your owning any fraction of a share of Union Planters common stock,
you will receive cash (without interest) instead of stock for that fraction.
Union Planters common stock is traded on the New York Stock Exchange under the
symbol "UPC". Based on the closing price of Union Planters common stock on
November 27, 1998, and the 2.83 to 1 exchange ratio, you will receive shares of
Union Planters common stock that had a market value on November 27, 1998 of
$138.49 for each share of LaPlace common stock. The market value of the Union
Planters stock you will receive in the merger will go up or down depending on
the market price of Union Planters common stock.

     Union Planters may increase the exchange ratio if the average closing price
of Union Planters stock during the 20 trading day period ending on the date of
the special meeting both falls below $48.45 and falls by more than 15% below the
relative performance of a group of comparable bank holding company common
stocks.
    

     This proxy statement-prospectus provides you with detailed information
about the proposed merger. In addition, you may obtain information about Union
Planters from documents filed with the SEC. We encourage you to read carefully
this entire document and the other documents that we refer you to in this
document.

     NEITHER THE SEC NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR
DISAPPROVED OF THE SHARES OF UNION PLANTERS COMMON STOCK TO BE ISSUED IN THE
MERGER OR DETERMINED IF THIS PROXY STATEMENT-PROSPECTUS IS ACCURATE OR COMPLETE.
ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

   
     The date of this proxy statement-prospectus is December 1, 1998. It is
first being mailed to shareholders on December 1, 1998.

                   A WARNING ABOUT FORWARD-LOOKING STATEMENTS

     This document contains forward-looking statements about Union Planters and
LaPlace and about Union Planters following the merger and other acquisitions by
Union Planters. These statements can be identified by our use of words like
"expect", "may", "could", "intend", "project", "estimate" or "anticipate". These
forward-looking statements reflect our current views, but they are based on
assumptions and are subject to risks, uncertainties and other factors. These
factors include the possibility that:

   
     (1)  we may not fully realize the expected cost savings from the merger and
          the other acquisitions;

     (2)  deposit attrition, customer loss, or revenue loss following the merger
          and the other acquisitions may be greater than we expected;

     (3)  competitive pressure in the banking industry may increase
          significantly;

     (4)  costs or difficulties related to the integration of the businesses of
          Union Planters and the institutions to be acquired may be greater than
          we expect;

     (5)  changes in the interest rate environment may reduce margins;

     (6)  general economic conditions, either nationally or regionally, may be
          less favorable than we expect, resulting in, among other things,
          deteriorating credit quality;

     (7)  changes may occur in the regulatory environment;

     (8)  changes may occur in business conditions and inflation;

     (9)  changes may occur in the securities markets; and

     (10) disruptions of the operations of Union Planters, LaPlace or any of
          their subsidiaries, or any other governmental or private entity may
          occur as a result of the "Year 2000 Problem."
    

     The forward-looking earnings estimates included in this proxy

THE COMPANIES   (SEE PAGE 61 FOR LAPLACE, PAGE 81 FOR UNION PLANTERS)

LaPlace Bancshares, Inc.
110 Belle Terre Blvd.
LaPlace, Louisiana  70068-3340
(504)652-2200

         LaPlace is a bank holding company incorporated in Louisiana. LaPlace
conducts its business activities through its wholly-owned subsidiary, Bank of
LaPlace. Bank of LaPlace is a full service commercial bank offering consumer and
commercial banking services in St. John the Baptist Parish, Louisiana. The bank

million.

Union Planters Corporation
7130 Goodlett Farms Parkway
Memphis, Tennessee 38018
(901)580-6000

         Union Planters is a registered bank holding company incorporated in
Tennessee. Through Union Planters Bank, National Association, its principal bank
subsidiary, and various other banking and banking-related subsidiaries, Union
Planters provides a diversified range of financial services in the communities
in which it operates. It maintains 801 banking offices and 1,000 automated
teller machines .

         Union Planters considers acquisitions an important part of its business
strategy and expects that they will continue to be important in the future.
During the period beginning January 1, 1994 and ending September 30, 1998, Union
Planters has completed 43 acquisitions adding approximately $26.4 billion to
Union Planters' assets. Union Planters also has pending agreements to acquire
five financial institutions, in addition to LaPlace, in four states, and an
agreement to purchase 56 branches and assume deposit liabilities of
approximately $1.8 billion in Indiana ("Indiana Branch Purchase"). These other
pending acquisitions had combined total assets of approximately $3.5 billion at
September 30, 1998.


                                        1

<PAGE>   11




         On September 30, 1998, Union Planters had consolidated assets of
approximately $30.5 billion, consolidated loans of approximately $19.7 billion,
consolidated deposits of approximately $23.3 billion, and consolidated
shareholders' equity of approximately $2.9 billion.

   
THE MERGER (SEE PAGE 20)

         Union Planters will acquire LaPlace by means of merging LaPlace with
Union Planters Holding Corporation, a wholly-owned subsidiary of Union Planters.
After the merger, Union Planters Holding Corporation, as the surviving
corporation in the merger, will continue to conduct LaPlace's business. The
merger agreement, which is an agreement between Union Planters Holding
Corporation and LaPlace and joined in by Union Planters, governs the whole
transaction. The plan of merger, which is attached to the agreement as an
exhibit, is an agreement between Union Planters Holding Corporation and LaPlace
that governs the merger of these two corporations. The merger agreement was 
entered on July 1, 1998.

WHAT YOU WILL RECEIVE IN THE MERGER (SEE PAGE 20)
    

         If the merger is completed, you will receive 2.83 shares of Union
Planters common stock for each share of your LaPlace common stock. Unless both
of the conditions described in the following paragraph exist, the number of
shares of Union Planters common stock you will receive in the merger will not
change, even if the market price of Union Planters common stock changes. As a
result, the market value of the Union Planters common stock you will receive in
the merger may be higher or lower than its current market value.

         The number of shares of Union Planters common stock might be increased;
however, if two conditions are met:

         (1)      The average closing price of Union Planters common stock
                  during the 20 trading days ending on the date of the special
                  meeting falls below $48.45; and

         (2)      Based on that average closing price, the price of Union
                  Planters common stock must have underperformed the common
                  stock price of a comparable group of bank holding companies
                  common stock by more than 15% following the fourth full
                  trading day after the announcement of the proposed merger.



                                        2

<PAGE>   12



         If both of these conditions exist, then LaPlace's board of directors
may decide not to complete the merger unless Union Planters increases the number
of shares to be issued to each holder of LaPlace common stock. Alternatively,
LaPlace's board of directors may decide to complete the merger even though Union
Planters refuses to increase the number of shares. In making that decision,
LaPlace's board of directors would consult its financial and legal advisors and
evaluate the financial condition of Union Planters and LaPlace and all relevant
facts and circumstances that exist at the time.

         Under no circumstances would the exchange ratio be less than 2.83
shares of Union Planters common stock for each share of LaPlace common stock.

         Union Planters will not issue any fractions of a share of common stock.
Rather, Union Planters will pay cash (without interest) for any fractional share
a LaPlace shareholder would otherwise receive in the merger. The cash payment
will be in an amount equal to the fraction multiplied by the closing price of
one share of Union Planters common stock on the NYSE on the last trading day
before the merger is completed.

OWNERSHIP OF UNION PLANTERS AFTER THE MERGER

         Union Planters will issue approximately 412,422 shares of Union
Planters common stock to LaPlace shareholders in the merger, assuming no
adjustment in the exchange ratio as discussed above. Based on that number, after
the merger, LaPlace shareholders will own approximately 0.30% of the outstanding
shares of Union Planters common stock. This information is based on the number
of shares of LaPlace and Union Planters common stock outstanding on October 31,
1998. It does not reflect shares that Union Planters may issue due to other
pending acquisitions or due to the exercise of Union Planters stock options, or
for other purposes.

   
DISSENTERS' RIGHTS (SEE PAGE 55)
    

         If the agreement and plan of merger is not approved by 80% or more of
LaPlace's total voting power, LaPlace shareholders who file a written objection
to the merger, vote against approval of the agreement and plan of merger, and
follow certain procedures set forth in Louisiana law will be entitled to
exercise dissenters' rights under Louisiana law. If dissenters' rights are
available, a LaPlace shareholder who complies with the required procedures will
not receive Union Planters common stock in the merger. Instead, if the merger is
completed, a dissenting shareholder will be entitled to demand payment of the
fair cash value of his LaPlace shares.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (SEE PAGE 24)

         We expect that, for federal income tax purposes, you will not recognize
any gain or loss upon the exchange of your shares for shares of Union Planters
common stock. You may recognize taxable gain or loss however, related to any
cash you receive in lieu of a fractional share of Union Planters common stock.
See discussion under "What You Will Receive in the Merger." Before the merger
can be completed, Union Planters and LaPlace expect to receive an opinion of
Wyatt, Tarrant & Combs and Arter & Hadden LLP substantially to this effect.
    

         Tax matters are very complicated and the tax consequences of the merger
to you will depend on your own situation. You should consult your own tax
advisors to determine the effect of the merger on you under federal, state,
local, and foreign tax laws.

COMPARATIVE MARKET PRICES OF COMMON STOCK

   
         Shares of Union Planters common stock are traded on the New York Stock
Exchange under the symbol "UPC". Shares of LaPlace common stock are not traded
on any exchange or in any other established trading market. On June 30, 1998,
the last trading day before we executed the agreement, Union Planters common
stock closed at $58.81 per share. On November 27, 1998, the latest practicable
date before the mailing of this proxy statement-prospectus, Union Planters
common stock closed at $48.9375 per share.

         The market value of 412,422 shares of Union Planters common stock would
be $24,254,538 based on Union Planters' June 30, 1998 closing price and
$20,182,902 based on Union Planters' November 27, 1998 closing price. We can
provide no assurance as to what the market price of the Union Planters common
stock will be if and when the merger is completed. You should obtain current
stock price quotations for Union Planters common stock. In addition, as
described below, the number of shares of Union Planters common stock to be
issued in connection with the merger may be subject to adjustment under certain
very limited circumstances.

OUR REASONS FOR THE MERGER (SEE PAGE 27)

         The LaPlace board unanimously approved the merger agreement. Your board
of directors believes that the merger will provide significant value to you and
will enable you to participate in opportunities for growth that the merger makes
possible. In deciding to approve and recommend the merger agreement, the LaPlace
board considered the following factors, among other factors:
    

   
          -    the financial terms of the merger agreement;
    

          -    the liquidity the merger will afford LaPlace shareholders;

          -    the respective dividend policies of Union Planters and LaPlace;



                                        4

<PAGE>   14



          -    information concerning the financial condition, results of
               operations and prospects of Union Planters and LaPlace;

          -    the market price of Union Planters common stock;

          -    the tax-free nature of the merger to LaPlace's shareholders, to
               the extent Union Planters common stock is received, for federal
               income tax purposes;

          -    the financial terms of other business combinations in the banking
               industry; and

          -    the opinion of LaPlace's financial advisor, Mercer Capital
               Management, Inc., that the exchange ratio of Union Planters
               common stock for LaPlace common stock in the merger is fair to
               LaPlace's shareholders from a financial point of view.

   
FAIRNESS OPINION OF LAPLACE'S FINANCIAL ADVISOR (SEE PAGE 29)

         In deciding to approve the merger, we considered an opinion from our
financial advisor, Mercer Capital Management, Inc., that the exchange ratio of
Union Planters common stock for LaPlace common stock in the merger is fair to
LaPlace's shareholders from a financial point of view. The full text of this
opinion is attached as Appendix D to this proxy statement-prospectus. We
encourage you to read this opinion in its entirety to understand the procedures
followed, assumptions made and matters considered by Mercer Capital in providing
its opinion.

SPECIAL MEETING OF SHAREHOLDERS  (SEE PAGE 18)

         The special meeting will be held at Bank of LaPlace, located at 110
Belle Terre Blvd., LaPlace, Louisiana at 5:30 p.m., local time, on December 30,
1998. At the special meeting, we will ask you:

          -    to approve the merger agreement; and
    

          -    to act on any other matters that may be put to a vote at the
               special meeting.

   
VOTING RIGHTS AT THE SPECIAL MEETING (SEE PAGE 19)

         You are entitled to vote at the special meeting if you owned shares of
LaPlace common stock as of the close of business on November 16, 1998, the
record date. On the record date, there were 145,732 shares of LaPlace common
stock outstanding. You will be entitled to one vote for each share of LaPlace
common stock you owned on the record date. You may vote either by attending the
special meeting and voting your shares or by completing the enclosed proxy card
and mailing it to us in the enclosed envelope.

         We are seeking your proxy for use at the special meeting. We have
prepared this proxy statement-prospectus to assist you in deciding how to vote
and whether or not to grant your proxy to us. If you sign a proxy, you may
revoke it at any time before the vote at the special meeting. If you have
elected not to attend the meeting, please indicate on your proxy card how you
want to vote. Then sign, date and mail it to us as soon as possible so that your
shares will be represented at the special meeting. If you sign, date and mail
your proxy card without indicating how you wish to vote, your proxy will be
counted as a vote for merger agreement. If you sign a proxy, you may revoke it
at any time before the special meeting or by attending and voting at the special
meeting. You cannot vote shares held in "street name"; only your broker can. If
you do not provide your broker with instructions on how to vote your shares,
your broker will not be permitted to vote them.

OUR RECOMMENDATION TO SHAREHOLDERS (SEE PAGE 20)

         Your board of directors unanimously approved the merger agreement. We
believe that the proposed merger is fair to you and in your best interests. We
unanimously recommend that you vote to approve the merger agreement.

SHAREHOLDER VOTE REQUIRED TO APPROVE THE MERGER (SEE PAGE 19)

         To approve the merger agreement, shareholders who own two-thirds of the
LaPlace voting power present, in person or by proxy, at the special meeting,
must vote for the merger agreement. Union Planters shareholders will not vote on
the merger.

SHARE OWNERSHIP OF MANAGEMENT AND CERTAIN SHAREHOLDERS; VOTING AGREEMENTS (SEE
PAGE 64)

         On the record date, your directors and executive officers
beneficially owned 58,062 shares, or approximately 39.84%, of the outstanding
shares of LaPlace common stock. As a condition to consummation of the merger,
each director and executive officer of LaPlace has executed a voting agreement
in which he agreed to vote all shares over which he has beneficial ownership for
approval of the agreement and plan of merger. On the record date, Bank of
LaPlace held no shares of LaPlace common stock in a fiduciary capacity for
others, or as a result of debts previously contracted.
    

         On the record date, Union Planters' directors and executive officers
owned no shares of LaPlace common stock and Union Planters held no shares of
LaPlace common stock in a fiduciary capacity for others, or as a result of debts
previously contracted.

   
INTERESTS OF CERTAIN PERSONS IN THE MERGER THAT MAY BE DIFFERENT FROM YOURS (SEE
PAGE 39)

         LaPlace's board of directors and certain officers may have interests in
the merger that differ from the interests of LaPlace shareholders generally.
Those interests include, among others, provisions in the merger agreement
regarding indemnification, insurance and eligibility to participate in certain
Union Planters employee benefit plans. Certain executive officers of LaPlace
also have interests in the merger that are different from other LaPlace
shareholders because they will terminate their existing employment agreements
with Bank of LaPlace and enter into employment agreements with a banking
subsidiary of Union Planters upon consummation of the merger. Your board of
directors was aware of these interests and considered them in approving and
recommending the merger.
    



                                        6

<PAGE>   16



   
EFFECTIVE TIME (SEE PAGE 34)

         The merger will become final when Articles of Merger become effective
with the Secretary of State of the State of Louisiana and the Secretary of State
of the State of Tennessee. If LaPlace shareholders approve the merger at the
special meeting, we currently anticipate that the merger will be completed on or
about December 31, 1998, or the day after the special meeting, although delays
could occur.

EXCHANGE OF STOCK CERTIFICATES  (SEE PAGE 37)
    

         Promptly after the merger is completed, you will receive a letter and
instructions on how to surrender your LaPlace stock certificates in exchange for
Union Planters stock certificates. You will need to carefully review and
complete these materials and return them as instructed along with your stock
certificates for LaPlace common stock. Please do not send LaPlace, Union
Planters or Union Planters' transfer agent any stock certificates until you
receive these instructions.

   
TERMINATION FEE (SEE PAGE 35)
    

         Under certain circumstances, if the merger is not consummated and
LaPlace enters into a letter of intent or agreement with a third party
concerning an acquisition proposal other than the merger, or supports or
indicates an intention to support an acquisition proposal other than the merger,
it will be required to pay $800,000 to Union Planters.

   
REGULATORY APPROVAL AND OTHER CONDITIONS (SEE PAGE 37)
    

         Union Planters is required to notify and get approvals from certain
government regulatory agencies, including the Board of Governors of the Federal
Reserve System, before the merger may be completed. The Federal Reserve approved
Union Planters' application to acquire LaPlace on September 24, 1998 provided
the merger is completed before December 24, 1998. By letter dated November 6,
1998, Union Planters has requested a 90-day extension of time in order to
complete the merger.

         In addition to the required regulatory approvals, the merger will be
completed only if certain conditions, including but not limited to the
following, are met:

   
          -    LaPlace shareholders must approve the merger agreement at the
               special meeting;

          -    LaPlace and Union Planters must receive an opinion of counsel
               that the merger will qualify as a tax-free reorganization;

          -    Union Planters must receive a letter from its accountants
               concerning the pooling-of-interests accounting treatment of the
               merger (discussed below under "Accounting Treatment");

          -    neither Union Planters nor LaPlace may have materially breached
               any of its representations or obligations under the merger
               agreement; and
    


                                        7

<PAGE>   17



   
          -    The New York Stock Exchange must have approved for listing the
               shares of Union Planters common stock to be issued in the merger.
    

         The agreement attached to this proxy statement-prospectus as Appendix A
describes other conditions that must be met before the merger may be completed.
Unless prohibited by law, either Union Planters or LaPlace could elect to waive
a condition that has not been satisfied and complete the merger anyway. We
cannot be certain whether or when any of these conditions will be satisfied, or
waived where permissible, or that we will complete the merger.

   
WAIVER, AMENDMENT, AND TERMINATION (SEE PAGE 37)

         Union Planters and LaPlace may agree to terminate the merger agreement
and not complete the merger at any time before the merger is completed.
    

         In addition, each of the parties can terminate the merger in certain
other circumstances, including the following:

   
          -    Either party may terminate the merger agreement if the merger is
               not completed by March 31, 1999. A party may not terminate the
               agreement; however, if (a) it willfully breached the agreement
               and (b) its breach is the reason the merger has not been
               completed.
    

          -    As previously noted, we can terminate the merger if Union
               Planters' stock price falls below certain levels and Union
               Planters does not increase the exchange ratio.

         The parties may also terminate the merger if other conditions occur.
These conditions are described in the agreement, which is attached to this proxy
statement-prospectus as Appendix A.

   
         The merger agreement may be amended by the written agreement of Union
Planters and LaPlace. The parties can amend the agreement without shareholder
approval, even if you have already approved the merger.

ACCOUNTING TREATMENT (SEE PAGE 41)
    

         Union Planters intends to account for the merger as a
pooling-of-interests transaction for accounting and financial reporting
purposes.

         Pooling-of-interests is an accounting method that assumes that each
company's shareholders have combined their ownership interests in such a manner
that each group becomes an owner of the combined, enlarged business. The key
differences between this method of accounting and the more common purchase
accounting method fall into two areas: income measurement and asset valuation.
Under pooling-of-interests, the earnings of each company are combined as though
the combination had occurred at the beginning of the earliest financial period
presented, or in the case of transactions which are not considered significant,
from the date of consummation forward. Under purchase accounting, the earnings
of the acquired company are included only after the closing of the merger. Under
pooling-of-interests, the assets of the acquired company are valued at their
historical cost. Under the purchase method, the


                                        8

<PAGE>   18



assets are valued at their fair value. The excess of the consideration the
acquiring company pays over the fair value of the target's assets is recorded as
goodwill.

   
CERTAIN DIFFERENCES IN SHAREHOLDERS' RIGHTS  (SEE PAGE 43)
    

         When the merger is completed, unless dissenters' rights are available
and you exercise your right to dissent, you will automatically become a Union
Planters shareholder. The rights of Union Planters shareholders differ from the
rights of LaPlace shareholders in certain important ways. Many of these
differences have to do with provisions in Union Planters' charter and bylaws and
Tennessee law. These provisions are intended to make a takeover of Union
Planters harder if the Union Planters board of directors does not approve it.

HISTORICAL AND PRO FORMA COMPARATIVE PER SHARE DATA

         The following table shows certain comparative per share data relating
to earnings (before extraordinary items and accounting changes), cash dividends,
and book value. The equivalent pro forma information assumes an exchange ratio
of 2.83 to 1.

   
         With the exception of the Indiana Branch Purchase and the pending
merger with First Mutual Bancorp, Inc. and First & Farmers Bancshares, Inc.,
which are expected to be accounted for using the purchase method of accounting,
the merger and the other acquisitions which Union Planters has pending are
expected to be accounted for using the pooling-of-interests method of
accounting. The LaPlace equivalent pro forma information reflects only the
acquisition of LaPlace because the other acquisitions which Union Planters
currently has pending are not considered significant to Union Planters from a
financial statement presentation standpoint. See "BUSINESS OF UNION
PLANTERS-RECENT DEVELOPMENTS for a discussion of Union Planters' other pending
acquisitions.
    

         We present the pro forma and equivalent pro forma data for your
information only. It does not necessarily indicate the results of operations or
combined financial position that would have resulted had Union Planters
completed the merger or the other acquisitions at the times indicated, and it
does not necessarily indicate what future results of operations or combined
financial position will be.

         You should read the information shown below in conjunction with the
historical consolidated financial statements of Union Planters and LaPlace and
the notes provided with them. In reviewing Union Planters' historical
information, please keep in mind that Union Planters has restated its historical
financial statements to reflect the impact of the several mergers completed in
the third quarter of 1998. You will find the restated numbers in Union Planters'
September 30, 1998 Quarterly Report on Form 10-Q, Exhibit 99.1. See "WHERE YOU
CAN FIND MORE INFORMATION," "-- Selected Financial Data," and "BUSINESS OF UNION
PLANTERS -- Recent Developments."

         Pro forma information for Union Planters and the pending acquisitions,
including LaPlace, has not been presented because the pending acquisitions are
not individually, or in the aggregate, considered material to Union Planters.

(1)  Union Planters' audited financial statements for the three years ended
     December 31, 1997 and the related management's discussion and analysis of
     results of operations and financial condition were restated for four
     acquisitions completed in the third quarter of 1998 and accounted for as
     poolings-of-interests. The 1997 restated audited financial statements (the
     "1997 Restated Financial Statements") and the restated management's
     discussion and analysis of results of operations and financial condition
     were filed as Exhibit 99.1 to Union Planters Quarterly Report on Form 10-Q
     dated September 30, 1998. Additionally, the selected financial data for
     1993 and 1994 has been restated to reflect the aforementioned four
     acquisitions.
(2)  Interim period ratios have been annualized where applicable.
(3)  Reference is made to Union Planters' Quarterly Report on Form 10-Q dated
     September 30, 1998 for a discussion of merger-related and other charges
     that significantly impacted operating results for the nine months ended
     September 30, 1998.
(4)  Share and per share amounts have been retroactively restated for
     significant acquisitions accounted for as poolings-of-interests and to
     reflect the changes in presentation of Earnings Per Share as discussed in
     Notes 2 and 16 to the 1997 Restated Financial Statements.
(5)  Long-term debt includes Medium-Term Notes, Federal Home Loan Bank advances,
     Trust Preferred Securities, variable rate asset-backed certificates,
     subordinated notes and debentures, obligations under capital leases,
     mortgage indebtedness, and notes payable with maturities greater than one
     year.
   
(6)  Average balances and calculations do not include the impact of the net
     unrealized gain or loss on available for sale securities.
    
(7)  FHA/VA government-insured/guaranteed loans have been excluded, since they
     represent minimal credit risk to Union Planters.

                                  RISK FACTORS

     If the merger is consummated, you will receive shares of Union Planters
common stock in exchange for your shares of LaPlace common stock. You should be
aware of particular risks and uncertainties that are applicable to an investment
in Union Planters common stock. Specifically, there are risks and uncertainties
that bear on Union Planters' future financial results and that may cause Union
Planters' future earnings and financial condition to be less than Union
Planters' expectations.

     Some of the risks and uncertainties relate to economic conditions generally
and would affect other financial institutions in similar ways. These aspects 
are discussed above under the heading "A WARNING ABOUT FORWARD-LOOKING 
STATEMENTS." This section addresses particular risks and uncertainties that are 
specific to Union Planters.

     Since December 31, 1997, Union Planters has acquired 14 financial 
institutions and has pending seven acquisitions, including the proposed merger. 
Union Planters' expectations concerning future earnings depend in part on Union 
Planters being able to combine the operations of the acquired institutions with 
Union Planters' own operations promptly and efficiently, and also on Union 
Planters being correct in its assumptions about the financial impact of the 
acquisitions.

     The risks and uncertainties that may affect Union Planters' future 
earnings and financial condition include the following:

- -    Union Planters' restructuring charges in recent acquisitions may be higher
     than expected.

     Union Planters has recorded restructuring and merger related charges in
     connection with the recently completed acquisitions and expects to record
     additional charges in connection with the merger and the other pending
     acquisitions. See "BUSINESS OF UNION PLANTERS" on page 81 for more
     information about these acquisitions. There is a risk that there may be
     additional costs and charges resulting from such transactions that exceed
     the charges Union Planters has recorded for financial reporting and
     accounting purposes.

- -    Union Planters may have more difficulty integrating acquired businesses or
     retaining key personnel than expected.

     Converting the systems and procedures of each acquired institution to Union
     Planters' system is an important part of Union Planters' acquisition
     program. Notwithstanding the extensive experience that Union Planters has,
     there is a risk that the conversion of an acquired institution may not be
     completed on schedule or may be more difficult and costly than expected.
     There is also a risk that Union Planters may not be able to retain key
     personnel of an acquired institution, which could cause the acquired
     operations to perform below expectations.
    


                                       16
<PAGE>   26
   
- -    Union Planters' operating costs after the merger and other recent
     acquisitions may be greater than expected, and Union Planters' costs
     savings from the merger and other recent acquisitions may be less than
     expected, or Union Planters may be unable to obtain those cost savings as
     soon as expected.

                     SPECIAL MEETING OF LAPLACE SHAREHOLDERS

DATE, PLACE, TIME, AND PURPOSE
   
            Union Planters and LaPlace are furnishing this proxy
statement-prospectus to holders of common stock, $1.00 par value, of LaPlace
("LaPlace Common Stock") in connection with the solicitation by the Board of
Directors of LaPlace of proxies for use at a special meeting of shareholders of
LaPlace to be held at      p.m., local time, on Thursday, December 31, 1998 at
the office of Bank of LaPlace, 110 Belle Terre Blvd., LaPlace, Louisiana, and at
any adjournment or postponement thereof.

            At the special meeting, shareholders will consider and vote upon a
proposal to approve an Agreement and Plan of Merger, dated July 1, 1998, between
Union Planters Holding Corporation and LaPlace, and joined in by Union Planters,
attached to this proxy statement-prospectus as Appendix A, and a related Plan of
Merger between LaPlace and Union Planters Holding Corporation, attached to this
proxy statement-prospectus as Appendix B, (the "Agreement" and the "Plan of
Merger" respectively). Pursuant to the Agreement and related Plan of Merger,
each share of LaPlace Common Stock outstanding immediately prior to the
effective time of the merger (except shares held by Dissenters, as hereinafter
defined), will be converted into and exchangeable for 2.83 shares of common
stock, $5.00 par value, of Union Planters ("Union Planters Common Stock"), and
associated Preferred Share Rights. For information about Union Planters'
Preferred Share Rights, see page 95. LaPlace shareholders will receive cash in
lieu of any fractional shares. As a result of the merger, the holders of LaPlace
Common Stock (other than shares held by Dissenters) will become shareholders of
Union Planters.
    

            This proxy statement-prospectus constitutes a proxy statement of
LaPlace with respect to the special meeting and a prospectus of Union Planters
with respect to the shares of Union Planters Common Stock to be issued in
connection with the merger. The information in this proxy statement-prospectus
concerning Union Planters and its subsidiaries and LaPlace and its subsidiary
has been furnished by each of such entities, respectively.

            The principal executive office of Union Planters is located at 7130
Goodlett Farms Parkway, Memphis, Tennessee 38018, and its telephone number is
(901) 580-6000. The principal executive office of LaPlace is located at 110
Belle Terre Blvd., LaPlace, Louisiana 70068-3340, and its telephone number is
(504) 652-2200. As used in this proxy statement-prospectus, the terms "Union
Planters" and "LaPlace" refer to Union Planters Corporation and LaPlace
Bancshares, Inc., respectively, and where the context requires, to Union
Planters and LaPlace and their respective subsidiaries.

   
            This Proxy Statement-Prospectus is first being mailed to holders of
LaPlace Common Stock on or about December 1, 1998.
    

RECORD DATE, VOTING RIGHTS, REQUIRED VOTE, AND REVOCABILITY OF PROXIES

   
            The Board of Directors of LaPlace has fixed the close of business on
November 16, 1998 as the record date for determining holders of outstanding
shares of LaPlace Common Stock entitled to notice of and to vote at the special
meeting. Only holders of LaPlace Common Stock of record on the books of LaPlace
at the close of business on the record date are entitled to vote at the special
meeting or at any adjournment or postponement of the special meeting. As of the
record date, there were 145,732 shares of LaPlace Common Stock issued and
outstanding, each of which is entitled to one vote. The presence, in person or
by proxy, of a majority of the total voting power of LaPlace is necessary to
constitute a quorum of the shareholders to take action at the special meeting.
    

            Approval of the Agreement and Plan of Merger requires the approval
of two-thirds of the voting power present at the special meeting. An abstention
by a shareholder present at the special meeting in person or by proxy will have
the same effect as a vote against the Agreement and Plan of Merger, but failure
to return a properly executed proxy, or a broker submitting a proxy without
exercising discretionary authority with respect to approval of the Agreement and
Plan of Merger will not.

            Shares of LaPlace Common Stock represented by properly executed
proxies will be voted in accordance with the instructions indicated on the
proxies or, if no instructions are indicated, will be voted FOR the proposal to
approve the Agreement and Plan of Merger and in the discretion of the proxy
holders as to any other matter which may properly come before the special
meeting or any adjournment or postponement thereof.

            A shareholder who has given a proxy may revoke it at any time before
it is voted by (a) filing with the Secretary-Treasurer of LaPlace a notice in
writing revoking it or a duly executed proxy bearing a later date, or (b) voting
in person at the special meeting.

            On the record date, LaPlace's directors and executive officers,
including their immediate family members and affiliated entities owned 58,062
shares or approximately 39.84% of the outstanding shares of LaPlace Common
Stock. On the record date, Union Planters' directors and executive officers
owned no shares of LaPlace Common Stock.



                                       19

<PAGE>   29
            As a condition to consummation of the merger, each director and
executive officer of LaPlace has executed a voting agreement in which he agreed
to vote all shares over which he had beneficial ownership for approval of the
Agreement and Plan of Merger.

            On the record date, Union Planters held no shares of LaPlace Common
Stock in a fiduciary capacity for others, or as a result of debts previously
contracted, and LaPlace held no shares of LaPlace Common Stock in a fiduciary
capacity for others or as a result of debts previously contracted with respect
to which it has sole or shared voting power.

            Union Planters shareholders are not required to approve the
Agreement and Plan of Merger or the issuance of shares of Union Planters Common
Stock.

SOLICITATION OF PROXIES

            LaPlace and Union Planters will share the costs of soliciting
proxies. In addition to the use of the mail, proxies may be solicited by the
directors, officers and employees of LaPlace in person, or by telephone,
telecopier or telegram. Directors, officers and employees will not be
additionally compensated for solicitation but may be reimbursed for
out-of-pocket expenses incurred in connection with solicitation. Arrangements
will also be made with custodians, nominees and fiduciaries for the forwarding
of solicitation material to the beneficial owners of LaPlace Common Stock held
of record by such persons, and LaPlace may reimburse custodians, nominees and
fiduciaries for reasonable out-of-pocket expenses incurred for these services.

RECOMMENDATION

            LaPlace's board of directors has unanimously approved the Agreement
and Plan of Merger, and believes that the proposal to approve the Agreement and
the Plan of Merger is in the best interests of LaPlace and its shareholders.
LaPlace's board of directors recommends that the LaPlace shareholders vote FOR
approval of the Agreement and the Plan of Merger.


                           DESCRIPTION OF TRANSACTION

            The following information describes material aspects of the merger.
This description does not provide a complete description of all the terms and
conditions of the Agreement and the Plan of Merger. It is qualified in its
entirety by the Appendices hereto, including the text of the Agreement and the
Plan of Merger, which are attached as Appendices A and B, respectively, to this
proxy statement-prospectus. The Agreement and Plan of Merger are incorporated
herein by reference. You are urged to read the Appendices in their entirety.

GENERAL

            The Agreement provides for the acquisition of LaPlace by Union
Planters pursuant to the merger of LaPlace with and into Union Planters Holding
Corporation. Union Planters Holding Corporation is a Tennessee corporation and a
wholly-owned subsidiary of Union Planters. Union Planters Holding Corporation
will be the surviving corporation resulting from the merger.


                                       20

<PAGE>   30
At the time the Merger becomes effective, each share of LaPlace common stock
then issued and outstanding (except shares held by LaPlace, Union Planters and
their subsidiaries other than shares held in a fiduciary capacity or as a result
of debts previously contracted) will be converted into and exchanged for the
right to receive 2.83 shares of Union Planters common stock and the associated
Preferred Share Rights (the "Exchange Ratio"). The Exchange Ratio is subject to
possible adjustment as described below.

            No fractional shares of Union Planters common stock will be issued.
Rather, Union Planters will pay cash (without interest) in an amount equal to
such fractional part of a share of Union Planters common stock multiplied by the
closing price of Union Planters common stock on the NYSE (as reported by The
Wall Street Journal) on the last trading day before the merger becomes
effective.

            On the record date, LaPlace had 145,732 shares of common stock
issued and outstanding. Based on an Exchange Ratio of 2.83 to 1, upon completion
of the merger, Union Planters will issue approximately 412,422 shares of its
common stock to LaPlace shareholders. After the merger, Union Planters would
then have outstanding approximately 136,475,457 shares of common stock based on
the number of shares of Union Planters common stock outstanding on October 31,
1998 (not including shares Union Planters may issue in its other pending
acquisitions and shares it may issue pursuant to the exercise of Union Planters
stock options or for other purposes).

POSSIBLE ADJUSTMENT OF EXCHANGE RATIO

            Under certain circumstances, the Exchange Ratio could be adjusted
pursuant to certain provisions of the Agreement. UNDER NO CIRCUMSTANCES WOULD
THE EXCHANGE RATIO BE LESS THAN 2.83 SHARES OF UNION PLANTERS COMMON STOCK FOR
EACH SHARE OF LAPLACE COMMON STOCK. An adjustment could occur only if LaPlace 's
board of directors elects to terminate the Agreement pursuant to the provisions
of the Agreement, and if Union Planters then elects to avoid termination of the
Agreement by increasing the Exchange Ratio.

            LaPlace may elect to terminate the Agreement if both:

            (1)   the Average Closing Price (as defined below) is less than
                  $48.45; and

            (2)   (a) the number obtained by dividing the Average Closing Price
                      by $60.5625 (the "Union Planters Ratio")

                      is less than

                  (b) the number obtained by dividing the weighted average of
                      the closing prices of the common stock of the bank
                      holding companies defined as the "Index Group" in the
                      Agreement (the "Index Price") on the date of the special
                      meeting, by the Index Price on July 13, 1998 (the
                      "Starting Date"), less 15% (the "Index Ratio").

            Union Planters has the option to avoid termination of the Agreement
by LaPlace by


                                       21

<PAGE>   31



increasing the Exchange Ratio to equal the lesser of (1) the number obtained by
dividing the product of $48.45 and the Exchange Ratio by the Average Closing
Price or (2) the number obtained by dividing the product of the Index Ratio and
the Exchange Ratio by the number obtained by dividing the Average Closing Price
by $60.5625. If the merger is approved by LaPlace's shareholders, LaPlace's
board of directors could elect not to terminate the Agreement and to consummate
the merger without seeking another vote of the LaPlace shareholders even if
LaPlace has the right to terminate.

            The Average Closing Price is the average of the daily last sales
prices of Union Planters common stock as reported on the NYSE (as reported by
The Wall Street Journal, or, if not reported thereby, another authoritative
source as chosen by Union Planters) for 20 consecutive full trading days in
which such shares are traded on the NYSE ending at the close of trading on the
date of the special meeting.

            These conditions reflect Union Planters' and LaPlace's agreement
that LaPlace's shareholders will assume the risk of declines in the value of
Union Planters common stock to $48.45. Any adjustment of the Exchange Ratio
related to a decline in the price of Union Planters common stock below $48.45
would depend on whether the Average Closing Price of Union Planters common stock
performs below the weighted average market prices of a group of comparable bank
holding company common stocks (the Index Group referenced above) by more than
15%.

            In making its determination of whether to terminate the Agreement,
LaPlace's board of directors will take into account, consistent with its
fiduciary duties, all relevant facts and circumstances that exist at such time.
These factors may include information concerning the business, financial
condition, results of operations, and prospects of Union Planters (including the
recent performance of Union Planters common stock, the historical financial data
of Union Planters, customary statistical measurements of Union Planters'
financial performance, and the future prospects for Union Planters common stock
following the merger), and the advice of its financial advisors and legal
counsel. If LaPlace's board of directors elects to terminate the Agreement,
Union Planters would then determine whether to proceed with the merger at the
higher Exchange Ratio. In making this determination, the principal factors Union
Planters will consider include the projected effect of the merger on Union
Planters' pro forma earnings per share and whether Union Planters' assessment of
LaPlace's earning potential as part of Union Planters justifies the issuance of
an increased number of Union Planters' shares. If Union Planters declines to
adjust the Exchange Ratio, LaPlace may elect to proceed without the adjustment,
provided it does so within 12 days of the date the LaPlace shareholders approve
the merger. UNION PLANTERS IS UNDER NO OBLIGATION TO ADJUST THE EXCHANGE RATIO.

            The operation of the adjustment mechanism can be illustrated by
three scenarios. For purposes of the scenarios, it has been assumed that the
initial Exchange Ratio is 2.83, the Starting Price of Union Planters common
stock is $60.5625, and the Index Price, as of the Starting Date, is $100.



                                       22

<PAGE>   32



Scenario One: The first scenario occurs if the Average Closing Price is equal
            to $48.45 or more. Under this scenario, there would be no possible
            adjustment to the Exchange Ratio, even though the value of the
            consideration to be received by LaPlace shareholders could have
            fallen from a pro forma $60.5625 per share, as of the Starting Date,
            to $48.45 per share, as of the date the LaPlace shareholders approve
            the merger.

Scenario Two: The second scenario occurs if the Average Closing Price is less
            than $48.45 but does not represent a decline from the Starting Price
            of more than 15% more than the decline of the common stock prices of
            the Index Group. Under this scenario, there also would be no
            possible adjustment to the Exchange Ratio, even though the value of
            the consideration to be received by LaPlace shareholders would have
            fallen from a pro forma $60.5625 per share, as of the Starting Date,
            to an amount based on the then lower Average Closing Price of Union
            Planters common stock, as of the date the LaPlace shareholders
            approve the merger.

Scenario Three: The third scenario occurs if the Average Closing Price
            declines below $48.45, and the Union Planters Ratio is below the
            Index Ratio. Under this scenario, the adjustment in the Exchange
            Ratio is designed to ensure that the LaPlace shareholders receive
            shares of Union Planters common stock having a value (based upon the
            Average Closing Price) that corresponds to the lesser of $48.45 per
            share, or a price reflecting a 15% decline from the stock price
            performance reflected by the Index Group.

            For example, if the Average Closing Price were $42.39, and the
            ending Index Price, as of the date the LaPlace shareholders approve
            the merger, were $90, the Union Planters Ratio (.70) would be below
            the Index Ratio (.90 minus .15), LaPlace could terminate the
            Agreement unless Union Planters elected within five days to increase
            the Exchange Ratio to equal 3.03, which represents the lesser of (a)
            3.234 (the result of dividing $137.11 (the product of $48.45 and the
            2.83 Exchange Ratio) by the Average Closing Price ($42.39), rounded
            to the nearest thousandth) and (b) 3.03 (the result of dividing the
            Index Ratio (.75) times 2.83 by the Union Planters Ratio (.70),
            rounded to the nearest thousandth). Based upon the assumed $42.39
            Average Closing Price, the new Exchange Ratio would represent a
            value to the LaPlace shareholders of $128.44 per share.

            If the Average Closing Price were $42.39., and the ending Index
            Price, as of the date the LaPlace shareholders approve the merger,
            were $100, the Union Planters Ratio (.70) would be below the Index
            Ratio (.85, or 1.00 minus .15), LaPlace could terminate the
            Agreement unless Union Planters elected within five days to increase
            the Exchange Ratio to equal 3.234, which represents the lesser of
            (a) 3.234 (the result of dividing $137.11 (the product of $48.45 and
            the 2.83 Exchange Ratio) by the Average Closing Price ($42.39),
            rounded to the nearest thousandth), and (b) 3.436 (the result of
            dividing the Index Ratio (.85) times 2.83 by the Union Planters
            Ratio (.70), rounded to the nearest thousandth). Based upon the
            assumed $42.39 Average Closing Price, the new Exchange Ratio would
            represent a value to the LaPlace shareholders of $137.11 per share.



                                       23

<PAGE>   33


   
            Based on the $48.9375 closing price of Union Planters common stock
on November 27, 1998, the Exchange Ratio represents a value of $138.49 per share
of LaPlace common stock.
    

            The actual market value of a share of Union Planters common stock at
the effective time of the merger and at the time certificates for those shares
are delivered to LaPlace shareholders may be more or less than the Average
Closing Price. You are urged to obtain current market quotations for Union
Planters common stock. See "COMPARATIVE MARKET PRICES AND DIVIDENDS."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

            Union Planters and LaPlace have not and do not intend to seek a
ruling from the IRS as to the federal income tax consequences of the merger.
Instead, consummation of the merger is conditioned upon the receipt by Union
Planters of the opinion of its counsel, Wyatt, Tarrant & Combs, and the receipt
by LaPlace of the opinion of its counsel, Arter & Hadden LLP, as to the
following expected federal income tax consequences of the merger:

            (1)   The acquisition by Union Planters Holding Corporation of
                  substantially all of the assets of LaPlace in exchange for
                  shares of Union Planters common stock and the assumption of
                  liabilities of LaPlace pursuant to the merger will constitute
                  a reorganization within the meaning of Section 368(a) of the
                  Internal Revenue Code.

            (2)   LaPlace, Union Planters and Union Planters Holding Corporation
                  will each be "a party to a reorganization" within the meaning
                  of Section 368(b) of the Internal Revenue Code.

            (3)   No gain or loss will be recognized by LaPlace as a result of
                  the merger.

            (4)   No gain or loss will be recognized by Union Planters Holding
                  Corporation or Union Planters as a result of the merger.

            (5)   No gain or loss will be recognized by the shareholders of
                  LaPlace as a result of the exchange of LaPlace common stock
                  for Union Planters common stock pursuant to the merger, except
                  that a gain or loss will be recognized on the receipt of any
                  cash in lieu of a fractional share. Assuming that the LaPlace
                  common stock is a capital asset in the hands of the respective
                  LaPlace shareholders, any gain or loss recognized as a result
                  of the receipt of cash in lieu of a fractional share will be a
                  capital gain or loss equal to the difference between the cash
                  received and that portion of the holder's tax basis in the
                  LaPlace common stock allocable to the fractional share.

            (6)   The tax basis of Union Planters common stock to be received by
                  the shareholders


                                       24
<PAGE>   34



                  of LaPlace will be the same as the tax basis of the LaPlace
                  common stock surrendered in exchange therefor (reduced by any
                  amount allocable to a fractional share interest for which cash
                  is received).

            (7)   The holding period of the Union Planters common stock to be
                  received by shareholders of LaPlace will include the holding
                  period of the LaPlace common stock surrendered in exchange
                  therefor, provided the LaPlace shares were held as a capital
                  asset by the shareholders of LaPlace on the date of the
                  exchange.

            (8)   A shareholder of LaPlace who perfects his dissenters' rights
                  and who receives payment of the fair market value of his
                  shares of LaPlace common stock will be treated as having
                  received such payment in redemption of such stock. Such
                  redemption will be subject to the conditions and limitations
                  of Section 302 of the Internal Revenue Code.

            The tax opinions will not address, among other matters:

            (1)   state, local estate, foreign or other federal tax consequences
                  of the merger not specifically addressed in the opinion;

            (2)   federal income tax consequences to LaPlace shareholders who
                  are subject to special rules under the Internal Revenue Code,
                  such as foreign persons, tax-exempt organizations, insurance
                  companies, financial institutions, dealers in stocks and
                  securities, and persons corporations, who do not own such
                  stock as a capital asset;

            (3)   federal income tax consequence, affecting shares of LaPlace
                  common stock acquired as part of a hedge, straddle or
                  conversion transaction;

            (4)   the tax consequences of Union Planters, Union Planters Holding
                  Corporation and LaPlace of the inclusion in income of the
                  amount of the bad-debt reserve maintained by LaPlace and/or
                  its subsidiaries and any other amounts resulting from any
                  required change in accounting methods; and

            (5)   the tax consequences of Union Planters, Union Planters Holding
                  Corporation and LaPlace of any income and deferred gain
                  recognized pursuant to Treasury Regulations issued under
                  Section 1502 of the Internal Revenue Code.

            The tax opinions will be based on the Internal Revenue Code, the
Treasury Regulations promulgated under the Internal Revenue Code by the Internal
Revenue Service ("IRS"), judicial decisions and administrative pronouncements of
the IRS, all existing and in effect on the date of such opinions and all of
which are subject to change at any time, possibly retroactively. Any such change
could have a material impact on the conclusions contained in the following
discussion. Moreover, the opinions will represent only such counsel's best
judgment as to the expected federal income tax consequences of the merger and
are not binding on the IRS or the courts. The IRS may challenge the conclusions
stated in the opinions and shareholders of


                                       25

<PAGE>   35



LaPlace may incur the cost and expense of defending positions taken by them with
respect to the merger. A successful challenge by the IRS could have material
adverse consequences to the parties to the merger, including shareholders of
LaPlace and Union Planters.

            In rendering the tax opinions, counsel for Union Planters and
LaPlace have the right to rely, as to factual matters, solely on the continuing
accuracy of (1) the description of the facts relating to the merger contained in
the Agreement and this proxy statement-prospectus, (2) the factual
representations and warranties contained in the Agreement and this proxy
statement-prospectus and related documents and agreements, and (3) certain
factual matters addressed by representations made by certain executive officers
of LaPlace, Union Planters and Union Planters Holding Corporation, as further
described in the opinions. Events occurring after the date of the opinions could
alter the facts upon which the opinions are based. In such case, the conclusions
reached in the opinions and in this summary could be materially impacted.

            Accordingly, for all of the above reasons, shareholders of LaPlace
are urged to consult their own tax advisors as to the specific tax consequences
to them of the merger, including the applicability and effect of federal, state,
local and other tax laws, and the implications of any proposed changes in the
tax laws.

            The conditions relating to the receipt of the tax opinions may be
waived by both Union Planters and LaPlace. Neither Union Planters nor LaPlace
currently intends to waive the conditions relating to the receipt of tax
opinions. If the conditions relating to the receipt of tax opinions were waived
and the material federal income tax consequences of the merger were
substantially different from those described in this proxy statement-prospectus,
LaPlace would resolicit the approval of its shareholders prior to completing the
merger.

BACKGROUND OF AND REASONS FOR THE MERGER

            BACKGROUND. In the last several years, there has been a sharp
increase in the level of interest in and the number of acquisitions of financial
institutions in Louisiana. One of the responsibilities of the LaPlace Board is
to consider various strategic alternatives, including whether to affiliate with
a larger, more diversified financial organization, as viable opportunities might
arise.

            In late 1997 and early 1998, representatives of three regional bank
holding companies, including Union Planters, approached Thomas W. Smith, Jr.,
President of LaPlace, concerning whether the LaPlace Board would be interested
in discussing a possible business combination. The interest expressed by each of
these entities was unsolicited by LaPlace. Mr. Smith advised the LaPlace Board
of these preliminary inquiries, and, on January 26, 1998, LaPlace engaged Mercer
Capital Management, Inc. ("Mercer Capital") as its financial advisor to assist
it in evaluating its strategic alternatives and soliciting preliminary
indications of interest for the purchase of LaPlace from interested and capable
buyers.

            Mercer Capital contacted six regional financial institutions,
including all that had previously expressed any interest in acquiring LaPlace.
Three institutions, including Union


                                       26

<PAGE>   36
Planters, submitted preliminary indications of interest to Mercer Capital in
March 1998. Following discussions with Mercer Capital, Union Planters and
another financial institution submitted revised indications of interest to
Mercer Capital in which each company increased the consideration it was offering
to the LaPlace shareholders.

            On April 21, 1998, the LaPlace Board held a special meeting to
consider its strategic alternatives and the acquisition proposals that had been
submitted. At this meeting, a representative of Mercer Capital advised the Board
regarding its strategic alternatives and the competing proposals. Mercer Capital
expressed its willingness to opine affirmatively on the fairness of either of
the transactions to LaPlace's shareholders, from a financial point of view.
Following the meeting, at the direction of the LaPlace Board, LaPlace management
and Mercer Capital engaged in additional negotiations with the two companies
that had submitted the indications of interest deemed most attractive to LaPlace
and its shareholders by the LaPlace Board. Later that day, representatives of
Union Planters and LaPlace reached a preliminary agreement on the terms of a
business combination, including the consideration to be received by shareholders
of LaPlace, subject to Union Planter's completion of preliminary due diligence,
approval by LaPlace's and Union Planter's respective boards of directors,
execution of a definitive agreement among the parties and certain other
conditions. Over the next two months, Union Planters conducted a review of
LaPlace's and Bank of LaPlace's books and records, and representatives of
LaPlace and Union Planters, and their respective advisors, negotiated the terms
of the Agreement and related Plan of Merger, subject to approval by each party's
board of directors.

            The merger, Agreement and Plan of Merger were considered by the
Board of Directors of LaPlace at a special meeting held for that purpose on June
25, 1998. At the meeting, representatives of Mercer Capital advised the Board
regarding the proposed merger. Based upon the foregoing and their analysis of
the Merger and Agreement and Plan of Merger, the LaPlace Board determined that
the merger was in the best interests of LaPlace and its shareholders and
approved the merger, Agreement and Plan of Merger.

            REASONS FOR THE MERGER. In reaching its decision that the merger is
in the best interests of LaPlace and its shareholders, the LaPlace Board
consulted with its financial and other advisors, as well as with LaPlace's
management, and considered a number of factors, including without limitation,
the following:

            -     the financial condition and results of operations of, and
                  prospects for, each of Union Planters and LaPlace, and the
                  market price of Union Planters Common Stock;

            -     the respective dividend policies of Union Planters and
                  LaPlace;

            -     the amount and type of consideration to be received by the
                  holders of LaPlace Common Stock pursuant to the Agreement and
                  related Plan of Merger, and the financial terms of other
                  business combinations in the banking industry;


                                       27

<PAGE>   37



            -     the Union Planters Common Stock to be received pursuant to the
                  Agreement and related Plan of Merger will be listed for
                  trading on the New York Stock Exchange and provide holders of
                  LaPlace Common Stock with liquidity that presently is
                  unavailable to such holders because an active trading market
                  does not exist for the LaPlace Common Stock;

            -     the merger will allow holders of LaPlace Common Stock to
                  become shareholders of Union Planters, a regional bank holding
                  company that is one of the fifty largest bank holding
                  companies in the United States;

            -     the merger is expected to qualify as a tax-free reorganization
                  so that neither LaPlace nor its shareholders (except to the
                  extent that cash is received in respect of their shares) will
                  recognize any gain in the transaction (see "-- Certain Federal
                  Income Tax Consequences of the Merger"); and

            -     the opinion received from Mercer Capital that the
                  exchange ratio of Union Planters Common Stock for
                  LaPlace Common Stock in the merger is fair to LaPlace's
                  shareholders from a financial point of view (see
                  "Opinion of Financial Advisor").

            The LaPlace Board did not assign any specific or relative weight to
the foregoing factors in its considerations. The LaPlace Board believes that the
merger will provide significant value to the holders of LaPlace Common Stock and
will enable them to participate in opportunities for growth that the LaPlace
Board believes the merger makes possible.

            BASED ON THE FOREGOING, THE LAPLACE BOARD UNANIMOUSLY APPROVED THE
MERGER, AGREEMENT AND PLAN OF MERGER, AND UNANIMOUSLY RECOMMENDS THAT THE
HOLDERS OF LAPLACE COMMON STOCK VOTE "FOR" APPROVAL OF THE AGREEMENT AND PLAN OF
MERGER.

UNION PLANTERS' REASONS FOR THE MERGER.

            In adopting the Agreement, the Plan of Merger, and the merger, the
Union Planters' board of directors considered a number of factors concerning the
benefits of the merger. Without assigning any relative or specific weights to
the factors, the Union Planters board of directors considered the following
additional material factors:

            (1)   a review, based in part on a presentation by Union Planters'
                  management, of

   
                  -     The business, operations, earnings, and financial
                        condition, including the capital levels and asset
                        quality, of LaPlace on an historical, prospective, and
                        pro forma basis and in comparison to other financial
                        institutions in the area,

                  -     The demographic, economic, and financial characteristics
                        of the markets in which LaPlace operates, including
                        existing competition, history of the market areas with
                        respect to financial institutions, and average demand
                        for credit, on historical and prospective basis, and

                  -     The results of Union Planters' due diligence review of
                        LaPlace; and
    

            (2)   a variety of factors affecting and relating to the overall
                  strategic focus of Union Planters, including Union Planters'
                  desire to expand into markets in Louisiana and the business
                  lines pursued by LaPlace.

   
            Union Planters' board of directors determined that the merger was in
the best interests of Union Planters and its stockholders and unanimously
approved the proposed merger on June 18, 1998.

OPINION OF LAPLACE'S FINANCIAL ADVISOR

            GENERAL. On January 26, 1998, LaPlace engaged Mercer Capital to act
as its financial advisor in connection with the possible sale of LaPlace. Mercer
Capital is a nationally recognized business valuation and financial advisory
consulting firm and is regularly engaged in the valuation of financial
institutions and other businesses in connection with mergers and other business
combinations, and in business valuations for corporate and other purposes.
LaPlace selected Mercer Capital as its financial advisor on the basis of its
experience and expertise in transactions similar to the merger and its
reputation in the banking community.

   
            At the June 25, 1998 meeting of the LaPlace Board, Mercer Capital
delivered its oral opinion, subsequently confirmed in writing as of November 25,
1998, that the exchange ratio of Union Planters Common Stock for LaPlace Common
Stock in the merger is fair to LaPlace's shareholders from a financial point of
view. No limitations were imposed by LaPlace on Mercer Capital with respect to
the investigations made or procedures followed in rendering its opinion. The
full text of Mercer Capital's written opinion to the LaPlace Board, which sets
forth the assumptions made, matters considered, and limitations of the review by
Mercer Capital, is attached hereto as Appendix D and is incorporated herein by
reference and should be read carefully and in its entirety in connection with
this proxy statement-prospectus. The following summary of Mercer Capital's
opinion is qualified in its entirety by reference to the full text of the
opinion. Mercer Capital's opinion is addressed to the LaPlace Board of Directors
only and does not constitute a recommendation to any shareholder of LaPlace as
to how such shareholder should vote at the Special meeting.

            In connection with its opinion, Mercer Capital, among other things
reviewed: (i) the Agreement and the Plan of Merger; (ii) LaPlace's audited
consolidated financial statements for the years ended December 31, 1995, 1996
and 1997, and certain unaudited financial information for LaPlace and Bank of
LaPlace for the years ended December 31, 1995, 1996 and 1997 and the three
months ended March 31, 1998, June 30, 1998, and September 30, 1998; (iii) Union
Planters' annual reports to shareholders for the years ended December 31, 1995,
1996 and 1997; (iv) Union Planters' Annual Report on Form 10-K for the years
ended December 31, 1995, 1996 and 1997 and Quarterly Reports on Form 10-Q for
the quarters ended March 31, 1998, June 30, 1998, and September 30, 1998; (v)
Union Planters' proxy statements for 1996, 1997 and 1998; (vi) LaPlace's 1998
budget prepared by LaPlace management; (vii) public market pricing data of
publicly traded banks which Mercer Capital deemed comparable to Union Planters;
and (viii) transaction data involving other banks which have been acquired.
    

            Representatives of Mercer Capital also visited with LaPlace
management in LaPlace, Louisiana and Union Planters management in Memphis,
Tennessee. Factors considered by Mercer Capital in rendering its opinion
included: (i) the terms of the Agreement and the Plan of Merger; (ii) the arms'
length process by which the Agreement and the Plan of Merger were negotiated;
(iii) a review of Union Planters' historical financial performance, historical
stock pricing, the liquidity of its shares and pricing in relation to other
publicly traded bank holding companies; (iv) a review of LaPlace's historical
financial performance and projected financial performance; (v) tax consequences
of the merger for LaPlace shareholders; and (vi) the financial analysis of the
merger described below.


                                       29

<PAGE>   39



            In connection with its review, Mercer Capital did not independently
verify any of the foregoing information, and relied on such information and
assumed such information was complete and accurate in all material respects.
Mercer Capital did not compile nor audit LaPlace's or Union Planters' financial
statements, did not make an independent evaluation, appraisal or physical
inspection of the loan portfolio, adequacy of the allowance for loan losses or
other assets or liabilities of LaPlace or Union Planters, and did not review any
individual credit files. Further, Mercer Capital's opinion was based on the
assumption that the merger will be consummated in accordance with the terms of
the Agreement and the Plan of Merger, without any amendment thereto and without
waiver by LaPlace of any of the conditions to its obligations thereunder.

            Set forth below is a brief summary of the valuation analysis and
report presented by Mercer Capital to the LaPlace Board on April 21, 1998 and
June 25, 1998 in connection with its opinion.

            TRANSACTION SUMMARY. Mercer Capital noted that the exchange ratio in
the merger of 2.83 shares of Union Planters Common Stock for each share of
LaPlace Common Stock was determined through arms length negotiations between
LaPlace and Union Planters in which Union Planters agreed to pay $159.88 per
share in Union Planters Common Stock based upon Union Planters' 20 day average
closing price for the period ended immediately before the Agreement was
executed. The negotiated value of the transaction of $159.88 per share, or $23.3
million, represented 17.7x LaPlace's trailing twelve months earnings for the
period ended March 31, 1998 and 301% of LaPlace's reported book value at March
31, 1998. Mercer Capital cautioned, however, that because the exchange ratio in
the merger is fixed, the ultimate value of the Union Planters Common Stock to be
received by LaPlace shareholders in the merger will be contingent upon the value
of Union Planters Common Stock on the Effective Date of the merger.

            PRO FORMA ANALYSIS OF PER SHARE DATA. Mercer Capital analyzed the
changes in pro forma dividends per share, earnings per share and book value per
share from the perspective of LaPlace's shareholders. Mercer Capital did not
represent or warrant that the pro forma data reflected in this proxy
statement-prospectus would reflect that which was developed in its analysis.
Mercer Capital noted that the proposed terms of the merger would result in an
increased book value per share and earnings per share based upon the consensus
estimate for Union Planters' operating earnings per share as compared to
LaPlace's budgeted 1998 earnings. In addition, Mercer Capital stated that
LaPlace shareholders would benefit from an increase in dividends to $5.66 per
share from $1.00 per share as a result of the merger, based upon Union Planters'
current annualized quarterly dividend of $2.00 per share and the exchange ratio
of 2.83 shares of Union Planters Common Stock for each share of LaPlace Common
Stock.

            COMPARABLE TRANSACTION ANALYSIS. Mercer Capital reviewed the prices
paid for various banks which have been acquired based upon certain available
public information as compiled by SNL Securities. Mercer Capital noted that most
banking transactions are measured in terms of the price/book ("P/B"),
price/tangible book ("P/TB"), price/earnings ("P/E"), price/assets ("P/A") and
tangible book premium/core deposit ("TBP/CD") ratios.


                                       30

<PAGE>   40



            The bank acquisition data was divided into the following four
groups: (i) aggregate national acquisition data; (ii) banks based in the
Southwest; (iii) banks based in Louisiana; and (iv) banks with assets of $50
million to $100 million which produce a return on equity ("ROE") of 15%-20%. For
each group, average and median P/E, P/B, P/TB, P/A and TBP/CD ratios were
calculated for calendar years 1993-1997. The 1997 median P/E ratio and average
P/B, P/TB, P/A and TBP/CD ratios were then multiplied by LaPlace's respective
net income for the year ended December 31, 1997 and December 31, 1997 book
value, tangible book value, assets and core deposits to develop an overall
indicated range of value for LaPlace.

            The range of indicated multiples and values as applied to LaPlace's
1997 year-end financial data were as follows: (i) P/E 15.0x-19.8x, $18.0-$23.7
million; (ii) P/B 223%-260%, $16.5-$19.3 million; (iii) P/TB 231%-263%,
$17.1-$19.5 million; (iv) P/A 19.4%-23.6%, $13.1-$15.9 million; and (v) TBP/CD
14.6%-21.9%, $14.4-$18.0 million. Mercer Capital's analysis indicated an overall
range of value for LaPlace of $14.4 million to $23.7 million. Mercer Capital
noted that the assumed value of the merger with Union Planters of $23.3 million,
based upon an assumed trading price for Union Planters Common Stock of $56.50
per share, fell at the upper end of the cited range.

            DILUTION ANALYSIS. A dilution analysis was conducted whereby
hypothetical non-dilutive prices for LaPlace were generated under the assumption
that various potential buyers would structure an offer so that LaPlace's
pro-forma earnings per share would equal that of the assumed buyer based solely
on the shares issued to LaPlace's shareholders.

            The valuation analysis was based upon hypothetical non-dilutive
mergers with Union Planters, Regions Financial Corporation, Whitney Holding
Corporation, Hancock Holding Company, First American Corporation and Trustmark
Corporation. The analysis calculated a range of values for each assumed buyer
based upon LaPlace's 1997 earnings, plus after-tax cost savings that a buyer
might realize, less revenues lost from some core deposit run off of 0% to 10%.
Expense savings were assumed to range from 0% to 35% of LaPlace's non-interest
operating expenses.

            The analysis indicated a lower range of $19.4 million to $24.4
million assuming no expense savings and no core deposit run-off. The analysis
indicated a higher range of $28.9 million to $36.4 million assuming the buyer
credited LaPlace with a 35% reduction in overhead and a 10% run-off in core
deposits. In March 1998, at the time the valuation analysis was prepared, the
financial institutions in the analysis were trading at a range of 16x to 22x
estimated 1998 earnings. Union Planters was trading in the vicinity of $62 per
share and 16x estimated 1998 earnings, which resulted in an indicated range of
value for LaPlace of $19.4 million to $28.9 million. The negotiated price of
$23.3 million in the merger was based upon an average price of $56.50 per share
for Union Planters Common Stock, which would have produced a non-dilutive price
range for a Union Planters acquisition of LaPlace of $18.5 million to $26.6
million, based upon Union Planters' estimated 1998 earnings as reported in early
April. Mercer Capital observed that the assumed pricing of Union Planters' offer
of $23.3 million, based upon an assumed trading price for Union Planters Common
Stock of $56.50 per share, fell slightly above the midpoint of the range.


                                       31

<PAGE>   41



            Mercer Capital noted that the dilution analysis was predicated upon
the hypothetical buyer's earnings per share and public market stock price.
Mercer Capital explained that, the greater the buyer's P/E ratio, the higher the
price a buyer generally can pay without issuing additional shares and thereby
diluting its per share earnings. Mercer Capital also cautioned that the implicit
assumption in the analysis is that the buyer "pays" the seller for all expense
savings. Mercer Capital noted that in its opinion, buyers rarely credit the
seller with all expense savings, particularly when the seller is a small
community bank holding company.

            DISCOUNTED CASH FLOW ANALYSIS. A discounted cash flow ("DCF")
analysis was prepared to develop an estimate of value LaPlace shareholders might
realize assuming a merger was delayed five years. Indications of value derived
using the DCF method reflect interim cash flows (dividends) and a terminal cash
flow (the value of LaPlace at the end of the projection period), both discounted
to the present at an appropriate required rate of return.

            For purposes of its analysis, Mercer Capital prepared projections
which were reviewed by LaPlace management for overall reasonableness. Mercer
Capital did not warrant or represent that the projections could or would be
realized. The projections were prepared solely to derive a range of present
values for LaPlace based upon certain assumptions, including annual balance
sheet growth by LaPlace of 10%, return on assets ("ROA") of 1.85%-1.90%, and
distribution by LaPlace of approximately 45% of its earnings each year in order
to maintain LaPlace's equity-to-asset ratio at its then-current level.

            The terminal value was based upon the product of projected earnings
for 2002 of $2.0 million and a range of P/E ratios of 15x to 20x. The terminal
values and interim dividends were discounted to present values at rates of 12%
to 17%. The overall indicated range of present values given the noted
assumptions was $16.0 million to $25.2 million. Mercer Capital noted that the
assumed value of the merger of $23.3 million, based upon an assumed trading
price for Union Planters Common Stock of $56.50 per share, compared favorably
with the range of value derived from the DCF analysis.

            REVIEW OF UNION PLANTERS. Using public and other available
information, Mercer Capital compared the historical financial performance and
current market pricing of Union Planters with the following: (1) publicly traded
bank holding companies based in Mississippi, Alabama, Arkansas, Louisiana and
Tennessee; (2) publicly traded bank holding companies with $10 billion to $35
billion of assets; and (3) aggregate data for all publicly traded bank holding
companies. None of the companies considered in the comparison analysis are
identical to Union Planters.

            Based upon pricing data as of mid-June 1998, Mercer Capital
calculated that Union Planters was trading at 21.3x reported twelve month
earnings for the period ended March 31, 1998 and 15.7x and 13.7x 1998 and 1999
earnings, respectively, based upon First Call's median analysts' estimates of
Union Planters' operating earnings of $3.58 per share for 1998 and $4.10 per
share for 1999. By way of comparison, the comparable groups were trading at the
following multiples: (a) Mid-South Group - 21.2x trailing twelve month earnings,
18.8x estimated 1998 earnings, and 16.8x estimated 1999 earnings; (b) $10-$35
Billion Group - 21.4x trailing twelve month earnings, 18.2x estimated 1998
earnings, and 16.2x estimated 1999 earnings; and (c)


                                       32

<PAGE>   42



National Group - 22.4x trailing twelve month earnings, 18.4x estimated 1998
earnings, and 16.2x estimated 1999 earnings.

            Mercer Capital noted that Union Planters' P/B ratio was 266% as
compared to median P/B multiples of 260% for the Mid-South Group, 316% for the
$10-$35 Billion Group, and 259% for the National Group. Union Planters' dividend
yield was 3.56% compared to median yields of 1.82% for the Mid-South Group,
2.03% for the $10-$35 Billion Group, and 1.55% for the National Group.

            Union Planters' reported ROE and ROA for the twelve month period
ended March 31, 1998 were, respectively, 12.75% and 1.23% as compared to 13.29%
and 1.21% for the Mid-South Group, 16.29% and 1.32% for the $10-$35 Billion
Group, and 13.21% and 1.18% for the National Group. Mercer Capital noted that
Union Planters' historical financial statements included merger-related charges
for consummated acquisitions, and that growth through acquisitions had been a
key component of Union Planters' strategy. Mercer Capital stated that, in its
opinion, Union Planters has tended to trade at a discount to its peers in
relation to forward operating earnings estimates because of Union Planters'
active acquisition program.

            The summary set forth above does not purport to be a complete
description of the presentation by Mercer Capital to the LaPlace Board or of the
analyses performed by Mercer Capital. The preparation of a fairness opinion is
not necessarily susceptible to partial analysis or summary description. Mercer
Capital believes that its analyses and the summary set forth above must be
considered as a whole and that selecting a portion of its analyses and factors
would create an incomplete view of the process underlying the analyses set forth
in its presentation to the LaPlace Board of Directors. In addition, Mercer
Capital may have given certain analyses more or less weight than other analyses,
and may have deemed various assumptions more or less probable than other
assumptions, so that the ranges of valuations resulting from any particular
analysis described above should not be taken to be Mercer Capital's view of the
actual value of LaPlace or the combined companies. The fact that any specific
analysis has been referred to in the summary above is not meant to indicate that
such analysis was given greater weight than any other analysis.

            In performing its analyses, Mercer Capital made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond the control of LaPlace or Union
Planters. The analyses performed by Mercer Capital are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less favorable than suggested by such analyses. Such analyses were
prepared solely as part of Mercer Capital's analysis of the fairness of the
exchange ratio to the holders of LaPlace Common Stock. The analyses do not
purport to be appraisals or to reflect the prices at which a company might
actually be sold or the prices at which any securities may trade at the present
time or any time in the future. Mercer Capital used in its analyses various
projections of future performance prepared by the management of LaPlace. The
projections are based on numerous variables and assumptions that are inherently
unpredictable and must be considered not certain of occurrence as projected.
Accordingly, actual results could vary significantly from those set forth in
such projections.

            As described above, Mercer Capital's opinion and presentation to the
LaPlace Board were among the many factors taken into consideration by the Board
in making its determination to approve the Agreement and the Plan of Merger.

          Pursuant to its engagement letter with Mercer Capital, LaPlace paid
Mercer Capital an initial fee of $12,000. If the merger is consummated, Mercer
Capital will be paid an additional fee equal to 0.30% of the total consideration
involved in the merger. LaPlace has also agreed to reimburse Mercer Capital for
its reasonable out-of-pocket expenses in an amount not to exceed $5,000 without
the prior consent of LaPlace. LaPlace has agreed to indemnify Mercer Capital and
its partners, employees, consultants, agents and representatives against certain
liabilities, including liabilities under the federal securities laws. Neither
Union Planters nor LaPlace has paid Mercer Capital any other fees during the
last two years.

EFFECTIVE TIME OF THE MERGER

          Subject to the conditions to the obligations of the parties to effect
the merger, the merger will become effective when Articles of Merger reflecting
the merger become effective with the Secretary of State of the State of
Louisiana and the Secretary of State of the State of Tennessee. Unless Union
Planters and LaPlace agree otherwise, they will use reasonable efforts to cause
the merger to become effective on the date designated by Union Planters that is
within 15 days after the later of (1) the effective date of the last consent of
any regulatory authority having authority over and approving or exempting the
merger (taking into account any required waiting period), and (2) the date on
which LaPlace's shareholders approve the Agreement and the Plan of Merger. Union
Planters and LaPlace anticipate that the merger will become effective on or
about December 31, 1998.

          Union Planters and LaPlace cannot assure that the necessary
shareholder and regulatory approvals of the merger will be obtained or that
other conditions precedent to the merger can or will be satisfied. LaPlace and
Union Planters anticipate that all conditions to consummation of the merger will
be satisfied so that the merger can be completed on or about December 31, 1998.
However, completion of the merger could be delayed.

          Either LaPlace's or Union Planters' board of directors may terminate
the Agreement and the Plan of Merger if the merger is not completed by March 31,
1999, unless it is not completed because of the willful breach of the Agreement
by the party seeking termination. See "-- Conditions to Consummation of the
Merger" and "-- Waiver, Amendment, and Termination."

DISTRIBUTION OF UNION PLANTERS STOCK CERTIFICATES

          Promptly after the merger is completed, each former LaPlace
shareholder will be mailed a letter of transmittal and instructions for the
exchange of the certificates representing shares of LaPlace common stock for
certificates representing shares of Union Planters common stock. Union Planters
expects that one of its bank subsidiaries will serve as Exchange Agent.



                                       34

<PAGE>   44



          You should not send in your certificates until you receive a letter of
transmittal and instructions. After you surrender to the Exchange Agent
certificates for LaPlace common stock with a properly completed letter of
transmittal, the Exchange Agent will mail you a certificate or certificates
representing the number of shares of Union Planters common stock to which you
are entitled and a check for the amount to be paid in lieu of any fractional
share (without interest), if any, together with all undelivered dividends or
distributions in respect of the shares of Union Planters common stock (without
interest thereon), if any. Union Planters will not be obligated to deliver the
consideration to you, as a former LaPlace shareholder, until you have
surrendered your LaPlace common stock certificates.

          Whenever a dividend or other distribution is declared by Union
Planters on Union Planters common stock with a record date after the date on
which the merger became effective, the declaration will include dividends or
other distributions on all shares of Union Planters common stock that may be
issued in the merger. However, Union Planters will not pay any dividend or other
distribution that is payable after the effective date of the merger to any
former LaPlace shareholder who has not surrendered his or her LaPlace common
stock certificate until the holder surrenders the certificate. If any LaPlace
shareholder's common stock certificate has been lost, stolen, or destroyed, the
Exchange Agent will issue the shares of Union Planters common stock and any cash
in lieu of fractional shares upon the shareholder's submission of an affidavit
claiming the certificate to be lost, stolen, or destroyed by the shareholder of
record and the posting of a bond in such amount as Union Planters will
reasonably direct as indemnity against any claim that may be made against Union
Planters with respect to the certificate.

          At the time the merger becomes effective, the stock transfer books of
LaPlace will be closed to LaPlace's shareholders and no transfer of shares of
LaPlace common stock by any shareholder will thereafter be made or recognized.
If certificates for shares of LaPlace common stock are presented for transfer
after the merger becomes effective, they will be canceled and exchanged for
shares of Union Planters common stock, a check for the amount due in lieu of
fractional shares, if any, and any undelivered dividends on the Union Planters
common stock.

TERMINATION FEE

          The agreement requires LaPlace to pay Union Planters $800,000 as
liquidated damages if LaPlace enters into a letter of intent, agreement in
principle, or definitive agreement with any third party with respect to an
acquisition proposal, or indicating an intent to support an acquisition
proposal, other than the merger. The sum is payable by LaPlace immediately upon
entering into a letter of intent, agreement in principle, or definitive
agreement concerning an acquisition proposal other than that contemplated in the
Agreement, unless the acquisition proposal results from a hostile takeover. In
that event the sum is due at the closing of the transaction. LaPlace's
obligation to pay these liquidated damages could extend to as late as September
30, 1999, in the event that the merger is not consummated or terminated for
certain specific reasons provided in the Agreement



                                       35

                  counsel as to the tax-free nature of the merger;

            (4)   the SEC must declare the registration statement, registering
                  the shares of Union Planters common stock to be issued to
                  LaPlace stockholders in the merger, effective under the
                  Securities Act of 1933, as amended;

            (5)   the shares of Union Planters common stock to be issued in the
                  merger must be approved for listing on the New York Stock
                  Exchange, subject to official notice of issuance;

            (6)   the representations and warranties of LaPlace and Union
                  Planters as set forth in the Agreement must be accurate as of
                  the date of the agreement and as of the date the merger
                  becomes effective;

            (7)   LaPlace and Union Planters must perform all agreements and
                  comply with all covenants of LaPlace and Union Planters as set
                  forth in the Agreement;

            (8)   LaPlace and Union Planters must receive all other consents
                  that may be required to complete the merger or to prevent any
                  default under any contract or permit which would be reasonably
                  likely to have, individually or in the aggregate, a material
                  adverse effect on LaPlace or Union Planters;

            (9)   Union Planters must receive a letter from
                  PricewaterhouseCoopers LLP to the effect that the merger will
                  qualify for pooling-of-interests accounting treatment;

            (10)  the absence of any law or order or any action taken by any
                  court, governmental, or regulatory authority of competent
                  jurisdiction prohibiting or restricting the merger or making
                  it illegal;

            (11)  Union Planters must receive agreements from each person
                  LaPlace reasonably believes may be deemed an affiliate of
                  LaPlace; and

            (12)  certain other conditions must be satisfied, including the
                  receipt of various certificates from the officers of LaPlace
                  and Union Planters.

            Neither Union Planters nor LaPlace can assure LaPlace shareholders
as to when or if all of the conditions to the merger can or will be satisfied or
waived by the party permitted to do so. If the merger is not effected on or
before March 31, 1999, the board of directors of either LaPlace


                                       36

<PAGE>   46



or Union Planters may terminate the Agreement and abandon the merger, unless the
failure to complete the merger was due to willful breach of the Agreement by the
party seeking to terminate. See "-- Waiver, Amendment, and Termination."

REGULATORY APPROVAL

          Union Planters must receive certain regulatory approvals before the
merger can be completed. There is no assurance that these regulatory approvals
will be obtained or when they will be obtained.

          It is a condition to the completion of the merger that Union Planters
and LaPlace receive all necessary regulatory approvals to the merger.

          LaPlace and Union Planters are not aware of any material governmental
approvals or actions that are required to complete the merger, except as
described below. Should any other approval or action be required, Union Planters
and LaPlace contemplate that they would seek such approval or action.

   
          The merger is subject to the prior approval of the Federal Reserve,
pursuant to Section 3 of the Bank Holding Company Act. Factors considered by the
Federal Reserve in evaluating the merger are discussed under the heading
"CERTAIN REGULATORY CONSIDERATIONS-General" on page 86. The merger may not
be completed until the 30th day following the date of the Federal Reserve
approval, although the Federal Reserve may reduce that period to 15 days. During
this period the United States Department of Justice is given the opportunity to
challenge the transaction on antitrust grounds. The commencement of any
antitrust action would stay the effectiveness of the approval of the agencies,
unless a court of competent jurisdiction specifically ordered otherwise. By
letter dated September 24, 1998, the Federal Reserve advised Union Planters that
it had approved the merger.
    

WAIVER, AMENDMENT, AND TERMINATION

          To the extent permitted by law, the Boards of Directors of Union
Planters and LaPlace may agree in writing to amend the Agreement, whether before
or after LaPlace's shareholders have approved the Agreement and the Plan of
Merger. In addition, before or at the time the merger becomes effective, either
LaPlace or Union Planters, or both, may waive any default in the performance of
any term of the Agreement by the other party or may waive or extend the time for
the compliance or fulfillment by the other party of any and all of its
obligations under the Agreement. In addition, either Union Planters or LaPlace
may waive any of the conditions precedent to its obligations under the
Agreement, unless a violation of any law or governmental regulation would
result. To be effective, a waiver must be in writing and signed by a duly
authorized officer of LaPlace or Union Planters, as the case may be.

          At any time before the merger becomes effective, the Boards of
Directors of Union Planters and LaPlace may agree to terminate the Agreement and
the Plan of Merger. In addition, either


                                       37

<PAGE>   47



LaPlace's board of directors or the Union Planters board of directors may
terminate the Agreement in the following circumstances:

          (1)         in certain circumstances, upon the inaccuracy of any
                      representation or warranty of a party contained in the
                      Agreement if the inaccuracy cannot be or has not been
                      cured within 30 days after the giving of written notice to
                      the breaching party of such inaccuracy (provided that the
                      terminating party is not itself then in breach of the
                      Agreement),

          (2)         if a material breach by the other party of any covenant or
                      agreement contained in the Agreement cannot be or has not
                      been cured within 30 days after the giving of written
                      notice to the breaching party of such breach (provided
                      that the terminating party is not itself then in breach of
                      the Agreement),

          (3)         if any consent of any regulatory authority required to
                      complete the merger has been denied by final nonappealable
                      action, or if any action taken by such authority is not
                      appealed within the time limit for appeal,

          (4)         if the shareholders of LaPlace fail to approve the
                      Agreement and the Plan of Merger at the special meeting,
                      or

          (5)         if the merger is not consummated by March 31, 1999,
                      provided that the failure to consummate is not caused by
                      any willful breach of the Agreement by the party electing
                      to terminate; and

   
LaPlace's board of directors may also terminate the Agreement pursuant to the
relevant provisions of the Agreement described in " -- Possible Adjustment of
Exchange Ratio" on page 21.
    

          If the merger is terminated, the Agreement and the Plan of Merger will
become void and have no effect, except that certain provisions of the Agreement,
including those relating to the obligations to share certain expenses and
maintain the confidentiality of certain information obtained, will survive.
Termination of the Agreement will not relieve any breaching party from liability
for any uncured willful breach of a representation, warranty, covenant, or
agreement. See "-- Expenses and Fees."

CONDUCT OF BUSINESS PENDING THE MERGER

          The Agreement obligates LaPlace to conduct its business only in the
usual, regular, and ordinary course before the merger becomes effective and
imposes certain limitations on the operations of LaPlace and its banking
subsidiaries. These items are listed in Article 7 of the Agreement which is
attached as Appendix A to this proxy statement-prospectus. The Agreement
authorizes LaPlace to declare and pay regular quarterly dividends on the LaPlace
common stock in accordance with its past practice in an amount not to exceed
$.25 per share per quarter during 1998 and $.75 per share per quarter during
1999. The Agreement contemplates that the merger will be timed to occur at such
a time that the LaPlace shareholders will not fail to receive a dividend during
a quarterly period, nor will they receive a dividend on both their LaPlace


                                       38

<PAGE>   48



common stock and the Union Planters common stock they receive in the merger
during the same quarterly period.

          LaPlace has also agreed that neither it nor any of its representatives
will directly or indirectly solicit any proposal for the acquisition of LaPlace
or, except to the extent necessary to comply with the fiduciary duties of
LaPlace's board of directors as advised by its counsel, furnish any non-public
information concerning LaPlace that it is not legally obligated to furnish,
negotiate with respect to, or enter into any contract with respect to, any
proposal to acquire LaPlace.

          Union Planters and LaPlace have also agreed not to take any action
that would (a) materially adversely affect their ability to obtain any consents
required for the merger or prevent the merger from qualifying for
pooling-of-interests accounting treatment or as a tax-free reorganization under
the Internal Revenue Code (see "-- Certain Federal Income Tax Consequences of
the Merger"), or (b) materially adversely affect their ability to perform their
covenants and agreements under the Agreement.

MANAGEMENT AND OPERATIONS AFTER THE MERGER

          The merger will not change the present management team or board of
directors of Union Planters. Information concerning the management of Union
Planters is included in the documents incorporated by reference in this proxy
statement-prospectus. See "WHERE YOU CAN FIND MORE INFORMATION."

          The current officers and directors of LaPlace's subsidiary bank may
continue to serve in their respective capacities on behalf of Bank of LaPlace.
Union Planters Holding Corporation, as the sole shareholder of Bank of LaPlace
after the merger, may change the composition of the bank's board of directors.
Union Planters currently expects that Bank of LaPlace will be merged into Union
Planters Bank, National Association as soon as practicable after the merger
becomes effective. At such time, executive officers of Bank of LaPlace could be
offered positions as regional officers and directors of Bank of LaPlace could be
offered positions as advisory directors of Union Planters Bank, National
Association. For additional information regarding the interests of certain
persons in the merger, see "-- Interests of Certain Persons in the Merger."

          Union Planters Holding Corporation will be the surviving corporation
resulting from the merger and will continue to be governed by the laws of the
State of Tennessee and operate in accordance with its charter and bylaws.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

          GENERAL. LaPlace's Board of Directors and certain officers may have
interests in the merger that differ from the interests of LaPlace shareholders
generally. The LaPlace Board was aware of these interests and considered them in
approving and recommending the merger.



                                       39

<PAGE>   49



          INDEMNIFICATION. The Agreement provides that Union Planters shall
indemnify the former directors, officers, employees and agents of LaPlace and
Bank of LaPlace against all claims to which they become subject arising out of
actions or omissions occurring at or prior to the Effective Date of the merger,
including the transactions contemplated by the Agreement to the full extent
permitted by Tennessee law, Louisiana law, LaPlace's Articles of Incorporation
and Bylaws, or any indemnity agreements previously entered into between LaPlace
or Bank of LaPlace and any present or former director, officer, employee or
agent of either of them.

          EMPLOYEE BENEFITS. The Agreement provides that, after the Effective
Date of the merger, Union Planters will, subject to compliance with applicable
legal and regulatory requirements, provide coverage for all employees of LaPlace
and Bank of LaPlace under Union Planters' benefit plans for which they are
eligible, as soon as practicable after the merger is completed. There will be no
waiting period for coverage of participants under any health, group term life
benefit plan, or 401(k) plan, and no employee will be denied benefits under any
such plan for pre-existing conditions. All prior years of service of Bank of
LaPlace employees will be counted for vesting and eligibility purposes under all
applicable Union Planters employee benefit plans to the extent permitted by
applicable law. Any Bank of LaPlace employee who, immediately prior to the
Effective Date, is covered by or is a participant in a Bank of LaPlace employee
benefit plan, shall on the Effective Date, be covered by or participate in the
comparable Union Planters employee benefit plan if a comparable plan otherwise
is maintained by Union Planters and if the eligibility requirements of the Union
Planters plan are met.

          EMPLOYMENT AGREEMENTS. Thomas W. Smith, Jr., who is the President of
LaPlace and Bank of LaPlace, and Patrick M. Guidry, who is the
Secretary-Treasurer of LaPlace and the Executive Vice President and Cashier of
Bank of LaPlace, currently have employment contracts (each, a "Prior Contract")
with Bank of LaPlace that provide for certain payments (each, a "Change in
Control Payment") to be made to them if they resign or are terminated without
cause (as defined in the agreements) within thirty days following a change of
control (such term, as defined in the agreements, includes the merger) of
LaPlace.

            Messrs. Smith and Guidry each have agreed to terminate their
respective Prior Contract and enter into a new employment agreement with Union
Planters, effective upon completion of the merger. Under his new employment
contract, which has a three-year term, Mr. Smith will, among other things, be
entitled to receive an incentive bonus of $462,000 if he is still employed by
Union Planters one year after the Effective Date of the merger. Mr. Guidry's new
employment contract has a one-year term, and provides, among other things, that
Mr. Guidry will be entitled to receive a $222,000 incentive bonus if he is still
employed by Union Planters one year after the Effective Date of the merger. The
dollar amount of these bonuses are approximately equal to the dollar amount of
the Change in Control Payment each officer would have been entitled to receive
under his Prior Contract if he resigned or was terminated within 30 days after
completion of the merger. In the event Messrs. Smith's or Guidry's employment
with Union Planters is terminated prior to the first anniversary of the
Effective Date of the merger because of such officer's death, disability,
resignation or termination for any reason other than such officer's conviction
for (or entry of a guilty or nolo contendere plea with respect to) a felony, he
will be entitled to receive a termination payment from Union Planters in an
amount equal to the Change in Control Payment


                                       40

he would have been entitled to receive under his Prior Contract if he resigned
or was terminated within thirty days after completion of the merger.

ACCOUNTING TREATMENT

            It is anticipated that the merger will be accounted for as a
pooling-of-interests. Under the pooling-of-interests method of accounting, the
recorded amounts of the assets and liabilities of LaPlace will be carried
forward at their previously recorded amounts. Since LaPlace is not considered
significant to Union Planters from a financial statement presentation
standpoint, the operating results will be included in Union Planters' results
from the Effective Time forward.

            In order for the merger to qualify for pooling-of-interests
accounting treatment, substantially all (90% or more) of the outstanding LaPlace
common stock must be exchanged for Union Planters common stock with
substantially similar terms. There are certain other criteria that must be
satisfied in order for the merger to qualify as a pooling-of-interests. Some of
the criteria cannot be satisfied until after the merger becomes effective. In
addition, it is a condition to closing the merger that PricewaterhouseCoopers,
LLP deliver a letter to Union Planters to the effect the merger will qualify for
pooling-of-interests accounting treatment.

            Certain conditions will be imposed on the exchange of LaPlace common
stock for Union Planters common stock in the merger by affiliates of LaPlace.
Certain restrictions will also be imposed on the transferability of the Union
Planters common stock received by those affiliates in the merger. These
conditions and restrictions will be imposed in order, among other things, to
ensure the availability of pooling-of-interests accounting treatment. For
information concerning these conditions and restrictions see "-- Resales of
Union Planters Common Stock."

EXPENSES AND FEES

            Union Planters and LaPlace will each pay its own expenses in
connection with the merger, including filing, registration and application fees,
printing fees, and fees and expenses of its own financial or other consultants,
investment bankers, accountants, and counsel, except that each of Union Planters
and LaPlace will bear and pay the filing fees and the printing and mailing costs
in connection with the registration statement and this proxy
statement-prospectus based on the relative asset sizes of Union Planters and
LaPlace at December 31, 1997.

RESALES OF UNION PLANTERS COMMON STOCK

            Union Planters common stock to be issued to shareholders of LaPlace
in the merger will be registered under the Securities Act of 1933, as amended
(the "Securities Act"). All shares of Union Planters common stock received by
shareholders of LaPlace in the merger will be freely transferable after the
merger by those shareholders of LaPlace who are not considered to be
"affiliates" of LaPlace or Union Planters. "Affiliates" generally are defined as
persons or entities who control, are controlled by, or are under common control
with LaPlace or Union Planters at the time of the special meeting (generally,
executive officers, directors, and 10% or greater shareholders).


                                       41

<PAGE>   51



            Rule 145 promulgated under the Securities Act of 1933, as amended,
restricts the sale of Union Planters common stock received in the merger by
affiliates of LaPlace and certain of their family members and related interests.
Under the rule, during the one year after the merger becomes effective,
affiliates of LaPlace or Union Planters may resell publicly the Union Planters
common stock they receive in the merger within certain limitations as to the
amount of Union Planters common stock they can sell in any three-month period
and as to the manner of sale. After the one-year period, affiliates of LaPlace
who are not affiliates of Union Planters may resell their shares without
restriction. Union Planters must continue to satisfy its reporting requirements
under the Securities Exchange Act of 1934, as amended (the "Exchange Act") in
order for affiliates to resell, under Rule 145, shares of Union Planters common
stock received in the merger. Affiliates also would be permitted to resell Union
Planters common stock received in the merger pursuant to an effective
registration statement under the Securities Act of 1933, as amended, or an
available exemption from the Securities Act of 1933, as amended, registration
requirements. This proxy statement-prospectus does not cover any resales of
Union Planters common stock received by persons who may be deemed to be
affiliates of LaPlace or Union Planters.

            SEC guidelines regarding qualifying for the "pooling-of-interests"
method of accounting also limit sales of shares of Union Planters and LaPlace by
their affiliates in connection with the merger. SEC guidelines 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.

            LaPlace has agreed to use its reasonable efforts to cause each
person who may be deemed to be an affiliate of LaPlace to execute and deliver to
Union Planters not later than 30 days prior to the effective time of the merger,
an agreement intended to ensure compliance with the Securities Act of 1933, as
amended, and to preserve the ability of the merger to be accounted for as a
"pooling-of-interests." Each LaPlace affiliate must agree not to sell, pledge,
transfer, or otherwise dispose of any LaPlace common stock held by the affiliate
except as contemplated by the Agreement or the affiliate agreement. In addition,
each LaPlace affiliate must agree not to sell, pledge, transfer or otherwise
dispose of any Union Planters common stock received in the merger (1) except in
compliance with the Securities Act of 1933, as amended, and the rules and
regulations under the Securities Act of 1933, as amended, and (2) until such
time as financial results covering 30 days of combined operations of Union
Planters and LaPlace have been published. Prior to publication of such results,
Union Planters will not transfer on its books any shares of Union Planters
common stock received by an affiliate in the merger. The stock certificates
representing Union Planters common stock issued to affiliates in the merger may
bear a legend summarizing these restrictions on transfer. See "-- Conditions to
Consummation of the Merger."

                 EFFECT OF THE MERGER ON RIGHTS OF SHAREHOLDERS

         In the merger, shareholders of LaPlace will exchange their shares of
LaPlace for shares of Union Planters. LaPlace is a Louisiana corporation
governed by Louisiana law and LaPlace's articles of incorporation and bylaws.
Union Planters is a Tennessee corporation governed by Tennessee law and Union
Planters' charter and bylaws. There are significant differences between the
rights of LaPlace shareholders and Union Planters' shareholders. The following
is a summary of the principal differences between the current rights of LaPlace
shareholders and those of Union Planters' shareholders.

   
         The following summary is not intended to be complete and is qualified
in its entirety by reference to the Louisiana Business Corporation Law (the
"Louisiana BCL") and the Tennessee Business Corporation Act as well as Union
Planters' charter and bylaws and LaPlace's articles of incorporation and bylaws.
Copies of the Union Planters charter and bylaws will be sent to holders of
LaPlace common stock upon request. See "WHERE YOU CAN FIND MORE INFORMATION" on
page 97.
    

ANTI-TAKEOVER PROVISIONS GENERALLY

         UNION PLANTERS. Union Planters' charter and bylaws contain certain
provisions designed to assist the Union Planters board of directors in playing
a role if any group or person attempts to acquire control of Union Planters so
that the Union Planters board of directors can further protect the interests of
Union Planters and its shareholders under the circumstances. These provisions
may help the Union Planters board of directors determine that a sale of control
is in the best interests of Union Planters' shareholders, or enhance the Union
Planters board of directors' ability to maximize the value to be received by
the shareholders upon a sale of control of Union Planters.

         Although Union Planters' management believes that these provisions are
beneficial to Union Planters' shareholders, they also may tend to discourage
some takeover bids. As a result, Union Planters' shareholders may be deprived
of opportunities to sell some or all of their shares at prices that represent a
premium over prevailing market prices. On the other hand, defeating undesirable
acquisition offers can be a very expensive and time-consuming process. To the
extent that these provisions discourage undesirable proposals, Union Planters
may be able to avoid those expenditures of time and money.

         These provisions also may discourage open market purchases by a company
that may desire to acquire Union Planters. Those purchases may increase the
market price of Union Planters Common Stock temporarily, and enable
shareholders to sell their shares at a price higher than that they might
otherwise obtain. In addition, these provisions may decrease the market price
of Union Planters Common Stock by making the stock less attractive to persons
who invest in securities in anticipation of price increases from potential
acquisition attempts. The provisions also may make it more difficult and time
consuming for a potential acquiror to obtain control of Union Planters through
replacing the board of directors and management. Furthermore, the provisions
may make it more difficult for Union Planters' shareholders to replace the
board of directors or management, even if a majority of the shareholders
believe that replacing the board of directors or management is in the best
interests of Union Planters. Because of these factors,


                                      43

<PAGE>   53

   
these provisions may tend to perpetuate the incumbent board of directors and
management. For more information about these provisions, see "--Authorized
Capital Stock," "--Amendment of Charter and Bylaws," "--Classified Board of
Directors and Absence of Cumulative Voting," "--Director Removal,"
"--Limitations on Director Liability," "--Indemnification," "--Special meetings
of Shareholders," "--Actions by Shareholders Without a Meeting," "--Shareholder
Nominations and Proposals" and "--Business Combinations."
    

AUTHORIZED CAPITAL STOCK

         UNION PLANTERS. Union Planters is authorized to issue 300,000,000
shares of Union Planters Common Stock, of which 136,063,035 shares were issued
and outstanding as of October 31, 1998, and 10,000,000 shares of no par value
preferred stock, of which 968,865 shares of Series E preferred stock were
issued and outstanding as of October 31, 1998. The Union Planters board of
directors may authorize the issuance of additional shares of Union Planters
Common Stock without further action by its shareholders, unless applicable laws
or regulations or a stock exchange on which Union Planters' capital stock is
listed requires shareholder action.

         Union Planters may issue, without a shareholder vote, shares of its
preferred stock, in one or more classes or series, with voting, conversion,
dividend, and liquidation rights as it specifies in its charter. The Union
Planters board of directors may determine, among other things, the distinctive
designation and number of shares comprising a series of preferred stock, the
dividend rate or rates on the shares of such series and the relation of such
dividends to the dividends payable on other classes of stock, whether the
shares of such series shall be convertible into or exchangeable for shares of
any other class or series of Union Planters capital stock, the voting powers,
if any, of such series, and any other preferences, privileges, and powers of
such series.

         In the event of the voluntary or involuntary liquidation, dissolution,
distribution of assets, or winding up of Union Planters, holders of preferred
stock will have priority over holders of Union Planters Common Stock.

         The authority to issue additional shares of Union Planters Common
Stock or preferred stock provides Union Planters with the flexibility necessary
to meet its future needs without the delay resulting from seeking shareholder
approval. The authorized but unissued shares of Union Planters Common Stock and
preferred stock may be issued from time to time for any corporate purpose,
including, stock splits, stock dividends, employee benefit and compensation
plans, acquisitions, and public or private sales for cash as a means of raising
capital. The shares could be used to dilute the stock ownership of persons
seeking to obtain control of Union Planters. The sale of a substantial number
of shares of voting stock to persons who have an understanding with Union
Planters concerning the voting of such shares, or the distribution or
declaration of a dividend of shares of voting stock (or the right to receive
voting stock) to its shareholders, may have the effect of discouraging or
increasing the cost of unsolicited attempts to acquire control of Union
Planters.

         Union Planters has a share purchase rights plan ("Preferred Share
Rights Plan") and distributed a dividend of one preferred share unit purchase
right ("Preferred Share Right") for


                                      44
<PAGE>   54
each outstanding share of Union Planters Common Stock. Under the Plan, one
Preferred Share Right is automatically distributed for each share of Union
Planters Common Stock. The Preferred Share Rights may deter coercive takeover
tactics and encourage persons interested in potentially acquiring control of
Union Planters to treat each shareholder on a fair and equal basis. Each
Preferred Share Right trades on the same basis with the share of Union Planters
Common Stock to which it relates until the occurrence of certain events. Upon a
potential change in control of Union Planters, the Preferred Share Rights would
separate from Union Planters Common Stock and each holder of a Preferred Share
Right (other than the potential acquiror) would be entitled to purchase equity
securities of Union Planters at prices below their market value. Union Planters
has authorized 750,000 shares of Series A preferred stock for issuance under
the Preferred Share Rights Plan. No shares have been issued as of the date of
this proxy statement-prospectus.

         LAPLACE. The authorized capital stock of LaPlace consists of 1,000,000
shares of LaPlace Common Stock, of which 145,732 shares were issued and
outstanding on the Record Date, and 1,000,000 shares of LaPlace preferred
stock, par value $1.00 per share, of which no shares were issued and
outstanding on the Record Date. The LaPlace Board is authorized to issue the
preferred stock in one or more series, and may fix and determine the relative
rights and preferences of such series, except that all series of preferred
stock must be identical except as to the rate of dividend; the price at, and
terms and conditions on which, shares of preferred stock may be redeemed; the
amount payable in the event of liquidation of LaPlace; sinking fund provisions;
the terms and conditions on which shares may be converted, if any; and voting
rights. The LaPlace board of directors is authorized to issue shares of its
capital stock for lawful consideration from time to time without a shareholder
vote.

AMENDMENT OF CHARTER AND BYLAWS

         UNION PLANTERS. Union Planters may amend its charter in any manner
permitted by Tennessee law. The Tennessee Business Corporation Act provides
that a corporation's charter may be amended by a majority of votes entitled to
be cast on an amendment, subject to any condition the board of directors may
place on its submission of the amendment to the shareholders. Union Planters'
charter requires a vote of two-thirds or more of the shares of capital stock
entitled to vote in an election of directors to amend the articles of the
charter governing directors and to remove a director from office, whether with
or without cause. A two-thirds vote is also required to amend, alter, or repeal
the article of the charter relating to business combinations.

         The Union Planters board of directors may adopt, amend, or repeal
Union Planters' bylaws by a majority vote of the entire board of directors. The
bylaws may also be amended or repealed by action of Union Planters'
shareholders.

         LAPLACE. Except with respect to certain amendments relating to
preferred stock, LaPlace may amend its articles by a vote of two-thirds of the
LaPlace voting power present, in person or by proxy, at a shareholders meeting,
the notice of which sets forth the proposed amendment or a summary of the
changes to be made thereby. The LaPlace bylaws may be amended by the vote


                                      45
<PAGE>   55

of a majority of a quorum of the LaPlace board, subject to the right of the
shareholders to change or repeal any bylaws.

CLASSIFIED BOARD OF DIRECTORS AND ABSENCE OF CUMULATIVE VOTING

         UNION PLANTERS. The Union Planters charter provides that the Union
Planters board of directors is divided into three classes, with each class to
be as nearly equal in number as possible. The directors in each class serve
three-year terms of office. The effect of Union Planters having a classified
board of directors is that only approximately one-third of the members of the
Union Planters board of directors are elected each year. As a result, two
annual meetings are required for Union Planters' stockholders to change a
majority of the members of the Union Planters board of directors.

         The purpose of dividing the Union Planters board of directors into
classes is to facilitate continuity and stability of leadership of Union
Planters by ensuring that experienced personnel familiar with Union Planters
will be represented on the board of directors at all times, and to permit Union
Planters' management to plan for the future for a reasonable amount of time.
However, by potentially delaying the time within which an acquirer could obtain
working control of the Union Planters board of directors, this provision may
discourage some potential mergers, tender offers, or takeover attempts.

         Pursuant to the Union Planters charter, each holder of Union Planters
common stock is entitled to one vote for each share of Union Planters common
stock held in the election of directors, and is not entitled to cumulative
voting rights in the election of directors. With cumulative voting, a
stockholder has the right to cast a number of votes equal to the total number
of such holder's shares multiplied by the number of directors to be elected.
The stockholder has the right to distribute all of his or her votes in any
manner among any number of candidates or to accumulate such shares in favor of
one candidate.

         Directors are elected by a plurality of the total votes cast by all
stockholders. With cumulative voting, it may be possible for minority
stockholders to obtain representation on the Union Planters board of directors.
Without cumulative voting, the holders of more than 50% of the shares of Union
Planters common stock generally have the ability to elect 100% of the Union
Planters board of directors. As a result, the holders of the remaining Union
Planters common stock effectively may not be able to elect any person to the
Union Planters board of directors. The absence of cumulative voting thus could
make it more difficult for a stockholder who acquires less than a majority of
the shares of Union Planters common stock to obtain representation on the Union
Planters board of directors.

         LAPLACE. LaPlace does not have a classified board of directors and
does not permit its shareholders to cumulate votes for directors.


                                      46
<PAGE>   56

DIRECTOR REMOVAL

         UNION PLANTERS. Union Planters' charter provides that a director may
be removed by the shareholders only if the shareholders holding at least
two-thirds of the voting power entitled to vote generally in the election of
directors vote for such removal. The purpose of this provision is to prevent a
majority shareholder from circumventing the classified board system by removing
directors and filling the vacancies with new individuals selected by that
shareholder. This provision may have the effect of impeding efforts to gain
control of the board of directors by anyone who obtains a controlling interest
in Union Planters common stock.

         LAPLACE. The bylaws of LaPlace provide that the shareholders may call
a meeting expressly for the purpose of removal of any director or the entire
Board of Directors, with or without cause, by a majority of the shares then
entitled to vote at an election of directors.

LIMITATIONS ON DIRECTOR AND OFFICER LIABILITY

         UNION PLANTERS. Union Planters' charter does not address the issue of
a director's or officer's liability to the corporation. Section 48-18-301 of
the Tennessee Business Corporation Act provides that a director shall not be
liable for any action, or failure to take action if he discharges his duties:

         (1)      in good faith;

         (2)      with the care of an ordinary prudent person in a like 
                  position under similar circumstances; and

         (3)      in a manner the director reasonably believes to be in the
                  best interests of the corporation.

In discharging his duties, a director may rely on the information, opinions,
reports, or statements, including financial statements, if prepared or
presented by officers or employees of the corporation whom the director
reasonably believes to be reliable. The director may also rely on such
information prepared or presented by legal counsel, public accountants or other
persons as to matters that the director reasonably believes are in the person's
competence.

         LAPLACE. The LaPlace articles provide that no director or officer of
LaPlace may be held personally liable to LaPlace or its shareholders for
monetary damages for breach of his or her fiduciary duty as a director or
officer, except for liability for: (i) breach of the director's or officer's
duty of loyalty to LaPlace or its shareholders, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) unlawful dividends or certain other unlawful distributions and (iv)
any transaction from which the director or officer derived an improper personal
benefit. The provisions of the Louisiana BCL do not differ substantially from
those of the Tennessee Business Corporation Act previously described.


                                      47
<PAGE>   57

INDEMNIFICATION

         UNION PLANTERS. Under the Tennessee Business Corporation Act, a 
corporation may indemnify any director against liability if the director:

         -        conducted himself or herself in good faith;

         -        reasonably believed, in the case of conduct in his or her
                  official capacity with the corporation, that his or her
                  conduct was in the best interests of the corporation;

         -        reasonably believed, in all other cases, that his or her
                  conduct was at least not opposed to the corporation's best
                  interests; and

         -        in the case of any criminal proceeding, had no reasonable 
                  cause to believe his or her conduct was unlawful.

         Unless limited by its charter, a Tennessee corporation must indemnify,
against reasonable expenses incurred by him or her, a director who was wholly
successful, on the merits or otherwise, in defending any proceeding to which he
or she was a party because he or she is or was a director of the corporation.
Expenses incurred by a director in defending a proceeding may be paid by the
corporation in advance of the final disposition of the proceeding if three
conditions are met:

         (1)      First, the director must furnish the corporation a written
                  affirmation of the director's good faith belief that he or
                  she has met the standard of conduct as set forth above;

         (2)      Second, the director must furnish the corporation a written
                  undertaking by or on behalf of a director to repay such
                  amount if it is ultimately determined that he or she is not
                  entitled to be indemnified by the corporation against such
                  expenses; and

         (3)      Third, a determination must be made that the facts then known
                  to those making the determination would not preclude
                  indemnification.

         A director may apply for court-ordered indemnification under certain
circumstances. Unless a corporation's charter provides otherwise,

         (1)      an officer of a corporation is entitled to mandatory
                  indemnification and is entitled to apply for court-ordered
                  indemnification to the same extent as a director;

         (2)      the corporation may indemnify and advance expenses to an
                  officer, employee, or agent of the corporation to the same
                  extent as to a director; and

         (3)      a corporation may also indemnify and advance expenses to an
                  officer, employee, or agent who is not a director to the
                  extent, consistent with public policy, that may be provided
                  by its charter, bylaws, general or specific action of its
                  board of directors, or contract.


                                      48
<PAGE>   58

         Union Planters' charter and bylaws provide for the indemnification of
its directors and officers to the fullest extent permitted by Tennessee law.

         LAPLACE. Louisiana law provisions regarding indemnification of a
corporation's directors, officers, employees and agents are similar to the
comparable provisions of Tennessee law discussed above, except that there is no
specific provision for court-ordered indemnification. LaPlace's bylaws provide
for indemnification of its directors and officers to the fullest extent
permitted by applicable law.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended, may be permitted to directors, officers, or
persons controlling Union Planters or LaPlace under the provisions described
above, Union Planters and LaPlace have been informed that, in the opinion of
the SEC, such indemnification is against public policy as expressed in the
Securities Act of 1933, as amended, and is therefore unenforceable.

SPECIAL MEETING OF SHAREHOLDERS

         UNION PLANTERS. Special meetings of Union Planters' shareholders may
be called for any purpose or purposes at any time by the Chairman of the Board,
the President, the Secretary, or the holders of not less than one-tenth of the
shares entitled to vote at such meeting.

         LAPLACE. Under the LaPlace bylaws, special meetings of the
shareholders, for any purpose or purposes, may be called by the President or
the Board of Directors, and shall be called by the Secretary upon the written
request of shareholder or shareholders holding in the aggregate not less than
one-fifth of the total voting power of LaPlace.

SHAREHOLDER NOMINATIONS AND PROPOSALS

         UNION PLANTERS. Union Planters' charter and bylaws do not address 
whether a shareholder may nominate members of the board of directors.

         Holders of Union Planters common stock are entitled to submit
proposals to be presented at an annual meeting of Union Planters shareholders.
Union Planters' bylaws provide that any proposal of a shareholder which is to
be presented at any annual meeting of shareholders must be sent so it is be
received by Union Planters not less than 120 days in advance of the anniversary
date of the proxy statement issued in connection with the previous year's
annual meeting.

         LAPLACE. LaPlace's articles and bylaws do not contain provisions
regarding shareholder nominations for the board of directors or the submission
of shareholder proposals at annual or special meetings.

BUSINESS COMBINATIONS

         UNION PLANTERS. Holders of two-thirds or more of the Union Planters
Common Stock


                                      49

<PAGE>   59

must approve a merger, consolidation, or a sale or lease of all or
substantially all of the assets of Union Planters if the other party to the
transaction is a beneficial owner of 10% or more of the outstanding shares of
Union Planters. A two-thirds vote is not required for any merger or
consolidation of Union Planters with or into any corporation or entity if a
majority of the outstanding shares of voting capital stock is owned by Union
Planters.

         The requirement of a supermajority vote of shareholders to approve
certain business transactions may discourage a change in control of Union
Planters by allowing a minority of Union Planters' shareholders to prevent a
transaction favored by the majority of the shareholders. Also, in some
circumstances, the board of directors could cause a two-thirds vote to be
required to approve a transaction and thereby enable management to retain
control over the affairs of Union Planters. The primary purpose of the
supermajority vote requirement is to encourage negotiations with Union
Planters' management by groups or corporations interested in acquiring control
of Union Planters and to reduce the danger of a forced merger or sale of
assets.

         As a Tennessee corporation, Union Planters is or could be subject to
certain restrictions on business combinations under Tennessee law, including,
but not limited to, combinations with interested shareholders. See the
discussion in the following section entitled "-- Takeover Statutes".

         LAPLACE. The LaPlace articles do not contain provisions regarding
voting requirements for business combinations. The Louisiana BCL states that
mergers, consolidations and sales of all or substantially all of the assets of
a Louisiana corporation must be approved by the shareholders by vote of at
least two-thirds of the voting power present, or such larger or smaller vote
(not less than a majority) of the voting power present or the total voting
power as the corporation's articles may require. Under the Louisiana BCL, share
exchanges require a similar shareholder vote by each class or series included
in the exchange.

         As a Louisiana corporation, LaPlace is or could be subject to certain
restrictions on business combinations under Louisiana law, including control
share acquisitions. See the discussion in the following section under
"--Takeover Statutes."

TAKEOVER STATUTES

         UNION PLANTERS. Tennessee has three anti-takeover acts which are
applicable to Union Planters, the Tennessee Business Combination Act, the
Tennessee Greenmail Act, and the Tennessee Investor Protection Act. The
Tennessee Control Share Acquisition Act does not apply to Union Planters,
because Union Planters' charter does not include a provision electing to be
covered by that act.

         The Tennessee Business Combination Act. The Tennessee Business
Combination Act generally prohibits a "business combination" by Union Planters
or a subsidiary with an "interested shareholder" within five years after the
shareholder becomes an interested shareholder. But Union Planters or a
subsidiary can enter into a business combination within that period if, before
the interested shareholder became such, the Union Planters board of


                                      50
<PAGE>   60

directors approved:

         -        the business combination or

         -        the transaction in which the interested shareholder became an
                  interested shareholder.

After that five year moratorium, the business combination with the interested
shareholder can be consummated only if it satisfies certain fair price criteria
or is approved by two-thirds of the other shareholders.

         For purposes of the Tennessee Business Combination Act, a "business
combination" includes mergers, share exchanges, sales and leases of assets,
issuances of securities, and similar transactions. An "interested shareholder"
is generally any person or entity that beneficially owns ten percent or more of
the voting power of any outstanding class or series of Union Planters stock.

         Tennessee law also severely limits the extent to which Union Planters
or any of its officers or directors could be held liable for resisting any
business combination. Under the Tennessee Business Corporation Act, neither a
Tennessee corporation having any stock registered or traded on a national
securities exchange, nor any of its officers or directors, may be held liable
for:

         -        Failing to approve the acquisition of shares by an interested
                  shareholder on or before the date the shareholders acquired
                  such shares;

         -        Seeking to enforce or implement the provisions of Tennessee 
                  law;

         -        Failing to adopt or recommend any charter or by-law amendment 
                  or provision relating to such provisions of Tennessee law; or

         -        Opposing any merger, exchange, tender offer, or significant
                  asset sale because of a good faith belief that such
                  transaction would adversely affect the corporation's
                  employees, customers, suppliers, the communities in which the
                  corporation or its subsidiaries operate or any other relevant
                  factor. But the officers and directors can only consider such
                  factors if the corporation's charter permits the board to do
                  so in connection with the transaction.

         The Tennessee Greenmail Act. The Tennessee Greenmail Act applies to a
Tennessee corporation that has a class of voting stock registered or traded on
a national securities exchange or registered with the SEC pursuant to Section
12(g) of the Exchange Act. Under the Tennessee Greenmail Act, Union Planters
may not purchase any of its shares at a price above the market value of such
shares from any person who holds more than 3% of the class of securities to be
purchased if such person has held such shares for less than two years, unless
the purchase has been approved by the affirmative vote of a majority of the
outstanding shares of each class of


                                      51
<PAGE>   61

voting stock issued by Union Planters or Union Planters makes an offer, of at
least equal value per share, to all shareholders of such class.

         The Tennessee Investor Protection Act. The Tennessee Investor
Protection Act generally requires the registration, or an exemption from
registration, before a person can make a tender offer for shares of a Tennessee
corporation which, if successful, would result in the offer or beneficially
owning more than 10% of any class. Registration requires the filing with the
Tennessee Commissioner of Commerce and Insurance of a registration statement, a
copy of which must be sent to the target company, and the public disclosure of
the material terms of the proposed offer. Additional requirements are imposed
under that act if the offer or beneficially owns 5% or more of any class of
equity securities of the target company, any of which was purchased within one
year prior to the proposed takeover offer. The Tennessee Investor Protection
Act also prohibits fraudulent and deceptive practices in connection with
takeover offers, and provides remedies for violations.

         The Tennessee Investor Protection Act does not apply to an offer
involving a vote by holders of equity securities of the offered company,
pursuant to its charter, on a merger, consolidation or sale of corporate assets
in consideration of the issuance of securities of another corporation, or on a
sale of its securities in exchange for cash or securities of another
corporation. Also excepted from the Tennessee Investor Protection Act are
tender offers which are open on substantially equal terms to all shareholders,
are recommended by the board of directors of the target company and include
full disclosure of all terms.

         The Tennessee Investor Protection Act applies to tender offers for
corporations with substantial ties in Tennessee, including corporations
incorporated in Tennessee or which have their principal offices in the state.
The Sixth Circuit Court of Appeals has held that the application of this act,
and Tennessee's other takeover statutes, to a target company that wasn't
organized under Tennessee law is unconstitutional. Tyson Foods, Inc. v.
McReynolds, 865 F.2d 99 (6th Cir. 1989).

         The acts described above, along with the provisions of Union Planters'
charter regarding business combinations, might be deemed to make Union Planters
less attractive as a candidate for acquisition by another company than would
otherwise be the case in the absence of such provisions. For example, if
another company should seek to acquire a controlling interest of less than
66-2/3% of the outstanding shares of Union Planters common stock, the acquiror
would not thereby obtain the ability to replace a majority of the Union
Planters board of directors until at least the second annual meeting of
shareholders following the acquisition. Furthermore the acquiror would not
obtain the ability immediately to effect a merger, consolidation, or other
similar business combination unless the described conditions were met.

         As a result, Union Planters' shareholders may be deprived of
opportunities to sell some or all of their shares at prices that represent a
premium over prevailing market prices in a takeover context. The provisions
described above also may make it more difficult for Union Planters'
shareholders to replace the Union Planters board of directors or management,
even if the holders of a majority of the Union Planters common stock should
believe that such replacement is in the


                                      52
<PAGE>   62

interests of Union Planters. As a result, such provisions may tend to
perpetuate the incumbent Union Planters board of directors and management.

         LAPLACE. Louisiana has one anti-takeover act which applies to LaPlace
- -- Louisiana's control share acquisition statute.

         The control share acquisition statute, sections 135 through 140.2 of
the Louisiana BCL, applies to "issuing public corporations," as defined in the
statute. LaPlace is an issuing public corporation because (1) it has 100 or
more shareholders; (2) it has its principal place of business, principal
office, or substantial assets in Louisiana; and (3) more than 10% of its
shareholders are Louisiana residents or more than 10% of its shares are held by
Louisiana residents. The statute generally provides that, when a person
acquires shares of an issuing public corporation that, together with shares
already owned, give such person ownership of one-fifth to one-third, one-third
to one-half, or more than one-half of the oustanding voting securities of such
corporation, the acquired shares, and any others acquired in the past ninety
days (collectively known as "control shares"), lose their voting rights.

         This voting power may be restored, however, in whole or in part, by a
vote of all shares other than Interested Shares (as defined below) at a meeting
called for the purpose of considering the voting power to be granted to the
acquiror's control shares. Interested Shares include all shares as to which the
acquiror, any officer of the issuing public corporation, and any director of
the issuing public corporation who is also an employee of the issuing public
corporation, may exercise or direct the exercise of voting power. If a meeting
of shareholders is held to consider the voting rights to be granted to an
acquiror's control shares and the shareholders do not vote to restore voting
rights to such shares, the issuing public corporation may have the right to
redeem the shares held by the acquiror for their fair market value. If such a
meeting is held and the shareholders vote to restore full voting rights to the
acquiror's control shares, all shareholders of the issuing public corporation
voting against the restoration of such voting rights gain dissenters' rights if
the acquiror, following the control share acquisition, owns a majority of the
issuing public corporation's voting shares.

         The control share acquisition statute does not apply to all
acquisitions of control shares. For example, the statute does not apply to
acquisitions by employee benefit plans or related trusts of the issuing public
corporation, or acquisitions pursuant to (i) succession law, (ii) the
satisfaction of a pledge or other security interest created in good faith and
not for the purpose of circumventing the statute, or (iii) a merger,
consolidation or share exchange effected under the Louisiana BCL if the issuing
public corporation, or a wholly-owned subsidiary of such corporation, is a
party to the agreement of merger or consolidation or plan of exchange.

DISSENTERS' RIGHTS OF APPRAISAL

         UNION PLANTERS. Under the Tennessee Business Corporation Act, a
shareholder is generally entitled to dissent from a corporate action and obtain
payment of the fair value of his shares in certain events. These events
generally include:

         (1)      mergers, share exchanges and sales of substantially all of
                  the corporation's assets other than in the usual and regular
                  course of business, if the shareholder is entitled to vote on
                  the transaction;

         (2)      certain types of amendments of the corporation's charter that
                  materially and adversely affects a shareholder's rights; or

         (3)      other corporate actions taken pursuant to a shareholder vote,
                  to the extent the charter, bylaws, or a resolution of the
                  board of directors provide for dissenters' rights. Union
                  Planters' charter and bylaws do not provide for any such
                  additional dissenters' rights.

Under the Tennessee Business Corporation Act, a shareholder will not have the
right to dissent as to any shares which are listed on a national securities
exchange registered under Section 6 of the Exchange Act or are national market
system securities under the Exchange Act rules. Union Planters common stock is
currently listed on the NYSE. Accordingly, shareholders of Union Planters will
NOT be able to assert dissenters' rights with respect to their shares of Union
Planters common stock even if Union Planters were to engage in one of the
actions listed above.

   
         LAPLACE. Shareholders of a Louisiana corporation are entitled to
dissenters' rights under Louisiana law in the event of certain mergers,
consolidations, share exchanges, or sale, lease or exchange of all of its
assets, where such transaction is approved by a vote of less than eighty
percent of the corporation's total voting power. A copy of Louisiana BCL ss.
131, which governs dissenters' rights under Louisiana law, is attached to this
proxy statement-prospectus as Appendix E. A discussion of such section follows.

         Under Section 131 of the Louisiana BCL, any holder of record of shares
of LaPlace Common Stock who files a written objection to the merger prior to or
at the Special meeting at which the vote on the merger is taken, and who votes
against the merger, may demand in writing to be paid in cash the fair cash value
of such shares, as of the day before the Special meeting, as determined by
agreement between the shareholder and Union Planters Holding Corporation or by a
state district court in St. John the Baptist Parish, Louisiana, if the
shareholder and Union Planters Holding Corporation are unable to agree upon the
fair cash value ("Dissenters' Rights"). IF THE MERGER AGREEMENT IS APPROVED BY
EIGHTY PERCENT (80%) OR MORE OF THE OUTSTANDING SHARES OF LAPLACE COMMON STOCK,
SECTION 131 OF THE LOUISIANA BCL PROVIDES THAT NO LAPLACE SHAREHOLDER WILL HAVE
DISSENTERS' RIGHTS. A person who is a beneficial owner, but not a registered
owner, of shares
    


                                      54
<PAGE>   64

of LaPlace Common Stock who wishes to exercise the rights of a dissenting
shareholder under the Louisiana BCL cannot do so in his own name and should
have the record ownership of the shares transferred to his or her name or
instruct the record owner thereof to take all required action to comply on his
behalf with the procedures under Section 131 of the Louisiana BCL.

         Any shareholder of record contemplating exercising Dissenters' Rights
is urged to review carefully the provisions of Section 131 of the Louisiana
BCL, particularly the procedural steps required to perfect Dissenters' Rights
thereunder. DISSENTERS' RIGHTS WILL BE LOST IF THE PROCEDURAL REQUIREMENTS OF
SECTION 131 ARE NOT FULLY SATISFIED.

   
         Set forth below is a summary of the procedures relating to the
exercise of Dissenters' Rights. The following summary does not purport to be a
complete statement of the provisions of Section 131 of the Louisiana BCL and is
qualified in its entirety by reference to Appendix E hereto and to any
amendments to such sections as may be adopted after the date of this proxy
statement-prospectus.
    

         FILING WRITTEN OBJECTION AND VOTE AGAINST THE MERGER. To exercise the
right of dissent, a shareholder (each a "Dissenter") must (i) deliver to
LaPlace a written objection to the Agreement and Plan of Merger prior to or at
the Special meeting AND ALSO (ii) vote the shares of LaPlace Common Stock held
by him (in person or by proxy) against the Agreement and Plan of Merger at the
Special meeting. Neither a vote against the Agreement and Plan of Merger nor a
specification in a proxy to vote against the Agreement and Plan of Merger will
in and of itself constitute the necessary written objection to the Agreement
and Plan of Merger. Moreover, by voting in favor of, or abstaining from voting
on, the Agreement and Plan of Merger, or by returning the enclosed proxy
without instructing the proxy holders to vote against the Agreement and Plan of
Merger, a shareholder waives his or her rights under Section 131 of the
Louisiana BCL.

         NOTICE OF THE EFFECTIVE DATE. If the Agreement and Plan of Merger are
approved by less than eighty percent (80%) of the outstanding shares of LaPlace
Common Stock, then, promptly after the Effective Date, notice will be given to
each Dissenter that the merger has become effective. The notice shall be sent
by registered mail addressed to the Dissenter at such Dissenter's last address
on LaPlace's records immediately prior to the Effective Date.

         WRITTEN DEMAND. Within twenty (20) days after the mailing of such
notice, a Dissenter must file with Union Planters Holding Corporation a demand
in writing (the "Demand") for payment of the fair cash value of such
Dissenter's shares as of the day prior to the Special meeting, stating the
amount demanded and a post office address to which Union Planters Holding
Corporation may reply. Simultaneously with the filing of the Demand, the
Dissenter shall also deposit the certificate(s) representing his shares of
LaPlace Common Stock (duly endorsed and transferred to Union Planters Holding
Corporation upon the sole condition that the certificate(s) will be delivered
to Union Planters Holding Corporation upon payment of the value of the shares
in accordance with Section 131 of the Louisiana BCL) in escrow with a chartered
bank or trust company located in St. John the Baptist Parish, Louisiana (the
"Escrow Bank"). Along with the Demand, the Dissenter shall deliver to Union
Planters Holding Corporation a written acknowledgment of the Escrow Bank that
it holds such certificate(s), endorsed as specified above.


                                      55
<PAGE>   65

         A Dissenter who fails to satisfy any of the foregoing conditions
within the proper time periods will conclusively be presumed to have acquiesced
to the merger and will forfeit any right to seek payment pursuant to Section
131 of the Louisiana BCL.

         APPRAISAL. If Union Planters Holding Corporation does not agree to the
amount demanded by the Dissenter, or does not agree that any payment is due, it
will within twenty (20) days after receipt of such Demand and acknowledgment,
notify such Dissenter in writing of either (i) the value it will agree to pay,
or (ii) its belief that no payment is due. If the Dissenter does not agree to
accept the offered amount, or disagrees with Union Planters Holding
Corporation's assertion that no payment is due, he must within sixty (60) days
after the receipt of such notice file suit against Union Planters Holding
Corporation in state court in St. John the Baptist Parish, Louisiana for a
judicial determination of the fair cash value of his shares. Any Dissenter who
is entitled to file such suit may, within such 60-day period but not
thereafter, intervene as a plaintiff in any suit filed against Union Planters
Holding Corporation by another former shareholder of LaPlace for a judicial
determination of the fair cash value of such other shareholder's shares. If a
Dissenter fails to bring or to intervene in such a suit within the applicable
sixty-day period, the Dissenter will be deemed to have consented to accept
either Union Planters Holding Corporation's statement that no payment is due
or, if Union Planters Holding Corporation does not contend that no payment is
due, to accept the value of his shares specified by Union Planters Holding
Corporation in its notice of disagreement (the "Notice of Disagreement").

         Shareholders considering exercising Dissenters' Rights should bear in
mind that the fair cash value of their shares determined under Section 131 of
the Louisiana BCL could be more than, the same as or less than the
consideration they would otherwise receive pursuant to the Agreement and
related Plan of Merger if they do not seek such rights, and that opinions of
financial advisors as to fairness are not opinions as to fair cash value under
Section 131 of the Louisiana BCL.

         Any Dissenter who has duly filed a Demand in compliance with Section
131 of the Louisiana BCL will, after filing the Demand, cease to have any of
the rights of a shareholder, except those rights generally provided to
Dissenters under Section 131 of the Louisiana BCL.

         A Dissenter has the right to voluntarily withdraw his or her Demand
and to accept the terms offered in the Agreement and related Plan of Merger at
any time before Union Planters Holding Corporation gives its Notice of
Disagreement, but thereafter the Dissenter may withdraw his or her Demand only
with the consent of Union Planters Holding Corporation. If a Demand is properly
withdrawn, or the Dissenter otherwise loses his Dissenters' Rights, the
Dissenter shall only be entitled to receive the consideration offered pursuant
to the Agreement and related Plan of Merger.

         PAYMENT AND COSTS. If upon the filing of a suit or intervention
against Union Planters Holding Corporation by a Dissenter pursuant to Section
131 of the Louisiana BCL, Union Planters Holding Corporation deposits with the
court the amount, if any, which it specified in its Notice of Disagreement, and
if in that notice Union Planters Holding Corporation offered to pay such amount
to the Dissenter on demand, then the costs (not including legal fees) of the
suit or intervention will be taxed against the Dissenter if the amount finally
awarded to the Dissenter, exclusive of interest and costs, is equal to or less
than the amount so deposited; otherwise, the costs (not including legal


                                      56
<PAGE>   66
fees) will be assessed against Union Planters Holding Corporation.

         NOTICES. Prior to the Effective Date, dissenting shareholders of
LaPlace should send any communications regarding their rights to Patrick M.
Guidry, Secretary-Treasurer, LaPlace Bancshares, Inc., 110 Belle Terre Blvd.,
LaPlace, Louisiana 70068-3340. On or after the Effective Date, dissenting
shareholders should send any communications regarding their rights to E. James
House, Jr., Secretary, Union Planters Holding Corporation, 7130 Goodlett Farms
Parkway, Memphis, Tennessee 38018. All such communications should be signed by
or on behalf of the dissenting shareholder in the form in which his or her
shares are registered on the books of LaPlace. UNION PLANTERS HAS THE RIGHT TO
TERMINATE THE AGREEMENT AND PLAN OF MERGER IF THE NUMBER OF SHARES OF LAPLACE
COMMON STOCK AS TO WHICH HOLDERS THEREOF ARE LEGALLY ENTITLED TO ASSERT
DISSENTERS' RIGHTS EXCEEDS TEN PERCENT (10%) OF THE OUTSTANDING SHARES OF
LAPLACE COMMON STOCK.

ANY LAPLACE SHAREHOLDER WHO DESIRES TO EXERCISE DISSENTERS' RIGHTS SHOULD
CAREFULLY REVIEW THE LOUISIANA BCL AND IS URGED TO CONSULT HIS LEGAL ADVISOR
BEFORE EXERCISING OR ATTEMPTING TO EXERCISE SUCH RIGHTS.

SHAREHOLDERS' RIGHTS TO EXAMINE BOOKS AND RECORDS

         UNION PLANTERS. The Tennessee Business Corporation Act provides that a
shareholder of a Tennessee corporation may inspect and copy books and records
of the corporation during regular business hours, if he or she gives the
corporation written notice of his or her demand at least five business days
before the date of the inspection. In order to inspect certain records, written
demand must also be made in good faith and for a proper purpose and must
describe with reasonable particularity the purpose of the request and the
records the stockholder desires to inspect.

         LAPLACE. The Louisiana BCL states that a shareholder, other than a
business competitor, who is and has been the owner of record of at least five
percent of the outstanding shares of any class of stock of a Louisiana
corporation for at least six months may inspect the records and accounts of the
corporation, and make extracts thereof. A shareholder who is a business
competitor may only examine the books and records of a Louisiana corporation if
he is and has been the owner of record for at least six months of at least 25%
of all outstanding shares of the corporation's stock. In either case, the
inspection must be at a reasonable time, for a proper and reasonable purpose,
and upon at least five days' written notice to the corporation.

DIVIDENDS

         UNION PLANTERS. Union Planters' ability to pay dividends on its common
stock is governed by Tennessee corporate law. Under Tennessee corporate law,
dividends may be paid so long as the corporation would be able to pay its debts
as they become due in the ordinary course of business and the corporation's
total assets would not be less than the sum of its total liabilities plus the
amount that would be needed, if the corporation were to be dissolved at the
time of the


                                      57
<PAGE>   67
distribution, to satisfy the preferential rights upon dissolution to
shareholders whose preferential rights are superior to those receiving the
distribution.

         There are various statutory limitations on the ability of the Union
Planters' banking subsidiaries to pay dividends to Union Planters. See "CERTAIN
REGULATORY CONSIDERATIONS -- Payment of Dividends."

         LAPLACE. LaPlace may pay dividends out of its surplus, unless it is
insolvent or the dividend payment would render it insolvent. In the absence of
surplus, it may pay dividends out of its net profits for the current year or
previous year or both, unless (i) its assets are, or would upon payment of the
dividend be, exceeded by its liabilities or (ii) its net assets are below or
the dividend would reduce its net assets below the aggregate amount payable on
liquidation based upon the issued shares, if any, which have a preferential
right to participate in the corporation's assets in the event of liquidation.

         Substantially all of the funds available to LaPlace to pay dividends
to its shareholders are derived from dividends paid to it by Bank of LaPlace,
which are subject to certain legal restrictions. See "BUSINESS OF LAPLACE -
Market Prices and Dividends" and "CERTAIN REGULATORY CONSIDERATIONS - Payment
of Dividends."

         On November 27, 1998, the last sale prices of Union Planters Common
Stock as reported on the NYSE was $48.9375 per share. On July 6, 1998, the
last business day prior to public announcement of the proposed merger, the last

         LaPlace has paid dividends of $1.00 per share for the years ended 1996
and 1997 and has paid dividends of $.75 per share through the three quarters
ended September 30, 1998.

         The holders of Union Planters Common Stock are entitled to receive
dividends when and if declared by the board of directors out of funds legally
available for the payment of such dividends. Although Union Planters currently
intends to continue to pay quarterly cash dividends on the Union Planters
Common Stock, there is no assurance that Union Planters' dividend policy will
remain unchanged after completion of the merger. The declaration and payment of
dividends thereafter will depend upon business conditions, operating results,
capital and reserve requirements, and the board of directors' consideration of
other relevant factors. The Agreement provides that LaPlace may not declare and
pay cash dividends, other than regular quarterly cash dividends, on the shares
of LaPlace Common Stock, without the consent of Union Planters.

         Union Planters and LaPlace are each legal entities separate and
distinct from their subsidiaries and their revenues depend in significant part
on the payment of dividends from their subsidiary depository institutions.
Union Planters' and LaPlace's subsidiary depository institutions are subject to
certain legal restrictions on the amount of dividends they are permitted to
pay. See "CERTAIN REGULATORY CONSIDERATIONS -- Payment of Dividends."


                              BUSINESS OF LAPLACE

DESCRIPTION OF THE BUSINESS

         LaPlace, a Louisiana corporation and a registered bank holding company
under the Federal Bank Holding Company Act of 1956 (the "BHC Act"), was
incorporated in 1982 to acquire the outstanding stock of Bank of LaPlace.
LaPlace has no other subsidiaries. At September 30, 1998, LaPlace had total
consolidated assets of approximately $67.7 million and total consolidated
shareholders' equity of approximately $8.3 million. LaPlace's principal
executive office is located at 110 Belle Terre Drive, LaPlace, Louisiana
70068-3340, and its


                                      59
<PAGE>   69
telephone number is (504) 652-2200.

         Bank of LaPlace was organized as a Louisiana state bank in 1980. Bank
of LaPlace provides full-service consumer and commercial banking services in
St. John the Baptist Parish in the State of Louisiana, through its main banking
office at 110 Belle Terre Drive, PaPlace, Louisiana. Deposits of Bank of
LaPlace are insured by the Federal Deposit Insurance Corporation ("FDIC") up to
applicable legal limits. Bank of LaPlace offers an array of deposit services,
including demand accounts, NOW accounts, certificates of deposit, and money
market accounts, and provides safe deposit boxes, night depository, individual
retirement accounts, and electronic and drive-in banking services. Bank of
LaPlace's lending activities consist principally of real estate, consumer and
commercial loans. At September 30, 1998, Bank of LaPlace had total deposits of
approximately $55.6 million and total loans of approximately $46.4 million.

   
         Bank of LaPlace's deposits and loans represent a cross-section of the
area's economy and there is no material concentration of deposits from any
single customer or group of customers. A concentration is defined as amounts
loaned to a multiple number of borrowers engaged in similar activities, which
could cause them to be similarly impacted by economic or other conditions,
where the amount exceeds 10% of total loans. Bank of LaPlace's loan portfolio
contains a concentration of loans to the real estate construction industry. At
September 30, 1998, Bank of LaPlace had outstanding approximately $8.6 million
of loans to borrowers in such industry, which represented approximately 18.5% of
total outstanding loans on that date. A significant portion of Bank of LaPlace's
loans are secured by mortgages on residential real estate located in St. John
the Baptist Parish, and may be susceptible to changes in local market
conditions.
    

PROPERTY

         The executive offices of LaPlace and Bank of LaPlace, located at 110
Belle Terre Drive, LaPlace, Louisiana are owned by LaPlace and are not subject
to mortgage. Bank of LaPlace leases approximately 22,021 square feet of office
space from LaPlace under a lease that expires in June 2004, subject to one
option to renew the lease for an additional ten-year term. A law firm that
provides professional services to Bank of LaPlace subleases 1,800 square feet
of this office space on a month-to-month basis under the terms of a lease that
expired in August 1995.

EMPLOYEES

         LaPlace has approximately 33 full-time and five part-time employees
and considers its relationship with its employees to be good. None of LaPlace's
employees are subject to a collective bargaining agreement.

COMPETITION

         LaPlace's general market area consists of St. John the Baptist Parish
in the State of Louisiana. This parish has an approximate population of 42,000
and contains five banks and two credit unions. As of June 30, 1997, the most
recent date for which information was available,


                                       60
<PAGE>   70
Bank of LaPlace was the second largest bank operating in St. John the Baptist
Parish, with approximately 20.4% of bank deposits. Hibernia National Bank and
First National Bank of Commerce, the largest and third largest banks with
offices in St. John the Baptist Parish, held approximately 58% and 18.1% of
parish bank deposits, respectively. The Bank experiences substantial
competition in attracting and retaining deposits and making loans.

         The primary factors in competing for deposits are interest rates, the
quality and range of financial services offered, convenience of office
locations and office hours. Competition for loan customers is generally a
function of interest rates, loan origination fees and other charges,
restrictive covenant and compensating balances and other services offered.
LaPlace competes with numerous other commercial banks, savings associations and
credit unions for customer deposits, as well as with a broad range of financial
institutions in consumer and commercial lending activities. In addition to
banks and savings associations, other businesses in the financial services
industry compete with LaPlace for retail and commercial deposit funds and for
retail and commercial loan business.

         Competition for loans and deposits is intense among the financial
institutions in the area. Several holding companies with greater resources than
LaPlace have established one or more branches in LaPlace's market area. The
size of these institutions allows certain economies of scale that permit their
operation on a narrower profit margin than would be appropriate for LaPlace.

MARKET PRICES AND DIVIDENDS

         MARKET PRICES.  LaPlace Common Stock is not traded on any exchange or 
in any other established public trading market. There are no bid or asked
prices available for LaPlace Common Stock.

   
         At November 16, 1998, there were 294 shareholders of LaPlace.
    

         CASH DIVIDENDS. LaPlace paid cash dividends of $1.00 per share in each
of 1997 and 1996, and did not pay cash dividends in 1995. The Merger Agreement
provides that LaPlace may not declare and pay cash dividends on LaPlace Common
Stock, other than regular cash dividends of up to $.25 per share during 1998
and $.75 per share during 1999, prior to the Effective Time or the termination
of the Merger Agreement, without the consent of Union Planters.

         LaPlace may pay dividends out of its surplus, unless it is insolvent
or the dividend payment would render it insolvent. In the absence of surplus,
it may pay dividends out of its net profits for the current year or previous
year or both, unless (i) its assets are, or would upon payment of the dividend
be, exceeded by its liabilities or (ii) its net assets are below or the
dividend would reduce its net assets below the aggregate amount payable on
liquidation based upon the issued shares, if any, which have a preferential
right to participate in the corporation's assets in the event of liquidation.


                                       61
<PAGE>   71
         Substantially all of the funds available to LaPlace to pay dividends
to its shareholders are derived from dividends paid to it by Bank of LaPlace,
which are subject to certain legal restrictions. With respect to Bank of
LaPlace, the prior approval of the Louisiana Commissioner of Financial
Institutions (the "Commissioner") is required if the total of all dividends
declared in any one year will exceed the sum of its net profits of that year
and net profits of the immediately preceding year. Additionally, dividends may
not be declared or paid by a Louisiana state bank unless the bank has
unimpaired surplus equal to 50% of the outstanding capital stock of the bank,
and no dividend payment may reduce the bank's unimpaired surplus below 50%. At
September 30, 1998, Bank of LaPlace had approximately $1,923,000 available for
the payment of dividends to LaPlace without prior approval of the Commissioner.

LEGAL PROCEEDINGS

         LaPlace and Bank of LaPlace normally are parties to and have pending
routine litigation arising from their regular business activities of furnishing
financial services, including providing credit and collecting secured and
unsecured indebtedness. In some instances, such litigation involves claims or
counterclaims against LaPlace and Bank of LaPlace, or either of them.

         On March 22, 1998, Robert J. Guidry ("R. Guidry") filed a petition in
the Civil District Court of Orleans Parish, Louisiana against Bank of LaPlace
and First National Bank of Commerce ("FNBC"). The petition sought to nullify a
January 1996 reversal by the Louisiana Fourth Circuit Court of Appeal of a 1994
judgment against Bank of LaPlace, FNBC and Patrick M. Guidry, an officer and
director of LaPlace and Bank of LaPlace. In the 1994 judgment, Bank of LaPlace
and Patrick Guidry were, collectively, found liable by the trial court for 15%
of a $4,540,000 judgment, or $681,000. After an appeal by all parties, with R.
Guidry seeking to have the judgment increased and Bank of LaPlace and Patrick
Guidry seeking to have it set aside, the judgment was reversed and rendered in
favor of Bank of LaPlace and Patrick Guidry by the Louisiana Fourth Circuit
Court of Appeal. The nullity petition sought to have the judgment of the Court
of Appeal nullified, and the original appeal reinstated, under Article 2004 of
the Louisiana Code of Civil Procedure, which allows for nullification of
judgments obtained by fraud or ill practices. The petition also alleged
violations of due process under the federal and state constitutions. Factually,
R. Guidry contends that there was an appearance of partiality because the
family of the son-in-law of one of the members of the three-judge appellate
panel is a shareholder in FNBC's holding company and because the same member of
the appellate panel has substantial loans from FNBC. Bank of LaPlace filed an
exception of no cause of action in response to the nullity petition. After a
hearing on June 19, 1998, the trial court granted Bank of LaPlace's exception
and dismissed the suit against both Bank of LaPlace and FNBC. R. Guidry has
appealed the dismissal of his nullity action. Bank of LaPlace intends to
vigorously defend this matter.

         Except as set forth above, as of September 30, 1998, LaPlace and Bank
of LaPlace did not have any litigation pending other than ordinary routine
litigation incidental to their business that was not material in amount in
respect of LaPlace's consolidated assets.

                LAPLACE BANCSHARES, INC. MANAGEMENT'S DISCUSSION
                       AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS

OVERVIEW

          LaPlace reported net income of $980,000 for the nine months ended
September 30, 1998, which represents an 8.5% increase from the net income of
$903,000 for the comparable period in 1997. Net income per share was $6.73 for
the nine months ended September 30, 1998 and $6.20 for the same period in 1997.
LaPlace's net income for 1997 was $1,197,000, a 5.1% increase from 1996 net
income of $1,139,000. Net income per share was $8.22 in 1997 and $7.82 in 1996.

          The improvements in net income between the first nine months of 1998
and the first nine months of 1997, and over the two years ended December 31,
1997, were principally attributable to increases in average earning assets,
improved net interest margin, and changes in the mix of earning assets.

          Net interest income during the first nine months of 1998 increased
$117,000 to $2,506,000, which represents a 4.9% increase over the same period of
1997. Net interest income in 1997 increased 13.0% from 1996, from $2,828,000 to
$3,195,000. The primary reasons for the increase from the first nine months of
1997 to the comparable period in 1998 were increases in average earning assets
and improved net interest margin. The increase from 1996 to 1997 is principally
attributable to volume change, although improved yields on earning assets and
changes in the mix of earning assets also contributed favorably.

          At September 30, 1998, LaPlace had total assets and deposits of
$67,749,000 and $55,628,000, respectively. Although total assets were
approximately the same as were reported at December 31, 1997, total deposits
increased 5.54% from amounts reported at December 31, 1997. Loans, net of the
reserve for possible loan losses, were $45,800,000 at September 30, 1998, an
increase of 3.9% from the amount reported at the end of 1997.

          The following table sets forth certain information regarding LaPlace's
results of operations for the periods indicated.

A more detailed review of LaPlace's financial condition and results of
operations for the years ended December 31, 1997 and 1996 and the nine months
ended September 30, 1998 and 1997 follows. This discussion and analysis should
be read in conjunction with LaPlace's financial statements and the notes thereto
appearing elsewhere in this Proxy Statement/Prospectus.

   
    

RESULTS OF OPERATIONS

            NET INTEREST INCOME. The principal component of LaPlace's net
earnings is net interest income, which is the difference between interest and
fees earned on interest-earning assets and interest paid on deposits and
borrowed funds. Net interest income, when expressed as a percentage of total
average interest-earning assets, is referred to as net interest margin. Net
interest income for the nine months ended September 30, 1998 increased to
$2,506,000 from $2,389,000 recorded for the comparable period in 1997, an
increase of 4.9%. 1997 net interest income of $3,195,000 represents an increase
of $367,000, or 13.0%, from net interest income of $2,828,000 reported for the
year ended December 31, 1996. The improvements over these periods were primarily
the result of increases in average earning assets, improved net interest margin,
and changes in the mix of earning assets.


                                       66
<PAGE>   76



            Average interest-earning assets were $63,364,000 for the nine months
ended September 30, 1998, $59,677,000 for the year ended December 31, 1997 and
$54,494,000 for the year ended December 31, 1996. Interest-earning assets were
up significantly in 1998 due to strong loan demand. Average loans, the Company's
highest yielding asset, rose 25.7% from 1996 to 1997 and 14.8% from the year
ended December 31, 1997 to the nine months ended September 30, 1998. Net
interest margin decreased 8 basis points to 5.27% for the nine months ended
September 30, 1998 from 5.35% recorded for 1997. 1997 net interest margin
represented a 16 basis point increase from 1996 net interest margin of 5.19%.

            LaPlace's net interest income is affected by the change in the
amount and mix of interest-earning assets and interest-bearing liabilities, and
by changes in yields earned on assets and rates paid on deposits and other
borrowed funds. The following table sets forth certain information concerning
average interest-earning assets and interest-bearing liabilities and the yields
and rates thereon for the periods presented. Average balances are computed using
year to date average balances.

            PROVISION FOR LOAN LOSSES. The provision for loan losses is the
periodic charge to earnings for potential losses in the loan portfolio. The
amounts provided for loan losses are determined by management after evaluations
of the loan portfolio. This evaluation process requires that management apply
various judgments, assumptions and estimates concerning the impact certain
factors may have on amounts provided. Factors considered by management in its
evaluation process include known and inherent losses in the loan portfolio, the
current economic environment, the composition of and risk in the loan portfolio,
prior loss experience and underlying collateral values. While management
considers the amounts provided through September 30, 1998 to be adequate,
subsequent changes in these factors and related assumptions may warrant
significant adjustments in amounts provided, based on conditions prevailing at
the time. In addition, various regulatory agencies, as an integral part of the
examination process, review LaPlace's allowance for loan losses. Such agencies
may require LaPlace to make additions to the allowance based on their judgments
of information available to them at the time of their examinations.

            The provision for loan losses for the nine months ended September
30, 1998 and 1997 was $90,000 and $90,000, respectively. The provision for loan
losses for the years ended December 31, 1997 and 1996 was $120,000 and $100,000,
respectively.

            NON-INTEREST INCOME. Non-interest income, excluding securities
transactions, was $1,703,000 for the nine months ended September 30, 1998,
compared to $1,387,000 for the comparable period of 1997. Non-interest income,
excluding securities transactions, was $1,836,000 for the year ended December
31, 1997, compared to $1,806,000 for 1996. The increase in non-interest income
from September 30, 1997 to the comparable period in 1998 was attributable
primarily to increased deposit service charges and mortgage banking fees.

            NON-INTEREST EXPENSE. Non-interest expense for the nine months ended
September 30, 1998 and 1997 was $2,638,000 and $2,336,000, respectively, a 12.9%
increase. Non-interest expense for the year ended December 31, 1997 increased to
$3,139,000 from $2,867,000 in 1996. The increase in non-interest expense during
these periods was attributable principally to significant expenditures made to
upgrade Bank of LaPlace's data processing capabilities.

            INCOME TAXES. LaPlace's provision for income taxes was $501,000 for
the nine months ended September 30, 1998, compared to $467,000 for the nine
months ended September 30, 1997.
Such provision was $596,000 for 1997 compared to $582,000 for 1996.

            IMPACT OF INFLATION. The effects of inflation on the local economy
and on LaPlace's operating results have been relatively modest for the past
several years. Because substantially all of LaPlace's assets and liabilities are
monetary in nature, such as cash, securities, loans and deposits, their values
are less sensitive to the effects of inflation than to changing interest rates,
which do not necessarily change in accordance with inflation rates. LaPlace
attempts to control the impact of interest rate fluctuations by managing the
relationship between its interest rate sensitive assets and liabilities.

            TOTAL ASSETS. At September 30, 1998, total assets were approximately
$67,749,000, compared to $67,714,000 at December 31, 1997 and $61,806,000 at
December 31, 1996. Total average assets as of September 30, 1998 were
$67,902,000, an increase of 5.6% from the $64,306,000 average for the year ended
December 31, 1997. Total average assets increased 9.0% from 1996 to 1997, from
$59,006,000 for the year ended December 31, 1996 to $64,306,000 for the year
ended December 31, 1997. The increases in average assets over these periods
reflect increased loan demand.

            SECURITIES. At September 30, 1998, LaPlace's securities portfolio
aggregated $16,160,000, a decrease of $1,530,000 from the $17,690,000 reported
at December 31, 1997, which reflects a decrease of $3,881,000 from the
$21,571,000 reported at December 31, 1996. The decrease in securities from 1996
to 1997 was principally attributable to increases in loan demand over the
period.

policy established by its Board of Directors. Each loan is evaluated based on,
among other things, character and leverage capacity of the borrower, cash flow,
collateral, market conditions for the borrower's business or project and
prevailing economic trends and conditions.

            At September 30, 1998, LaPlace had a concentration of loans to the
real estate construction industry. A concentration is defined as amounts loaned
to a multiple number of borrowers engaged in similar activities, which could
cause them to be similarly impacted by economic or other conditions, where the
amount exceeds 10% of total loans. At September 30, 1998, Bank of LaPlace had
outstanding approximately $8.6 million of loans to borrowers in such industry,
which represented approximately 18.5% of total outstanding loans on that date. A
significant portion of Bank of LaPlace's loans are secured by residential real
estate located in St. John the Baptist Parish, and may be susceptible to changes
in local market conditions.
    

            At September 30, 1998, loans were $46,359,000, as compared to
$44,602,000 at December 31, 1997 and $35,345,000 at December 31, 1996. Average
loans have increased over these periods as well, from $31,306,000 and
$39,346,000, respectively, for 1996 and 1997, to $45,176,000 for the nine months
ended September 30, 1998. These increases in the amount of outstanding loans are
attributable principally to increased loan demand in the market served by
LaPlace. These increases were the result of a strengthening local economy.
LaPlace's average loan to deposit ratio was 85.47% during the first nine months
of 1998 as compared to 78.47% and 68.94% during 1997 and 1996, respectively.

            At September 30, 1998, commercial, real estate and
consumer/installment loans comprised approximately 56.0%, 35.2% and 8.8%,
respectively, of total outstanding loans. This compares to 51.9%, 39.2% and 8.9%
categorized as commercial, real estate and consumer/installment loans,
respectively, at December 31, 1997 and 49.1%, 41.4% and 9.5% categorized as
commercial, real estate and consumer/installment loans, respectively, at
December 31, 1996.

            NONACCRUAL, PAST DUE AND MODIFIED LOANS. The performance of
LaPlace's loan portfolio is evaluated regularly by Senior Management and the
Board of Directors. Interest on loans is accrued daily as earned. A loan is
generally placed on nonaccrual status when principal or interest is past due 90
days or more, except on government guaranteed loans or when management
determines the loan remains likely to be fully collectible. Upon being placed on
nonaccrual status, the accrual of income from a loan is discontinued and
previously accrued but unpaid interest is reversed against income. Each loan
that is 90 days or more past due is evaluated to determine its collectibility
and the adequacy of its collateral.

            The following table sets forth the amount of LaPlace's nonperforming
loans (nonaccrual loans and loans past due 90 days or more and still accruing
interest) and loans with modified terms as of the dates indicated:

            As a percent of total loans, loans past due 90 days or more and not
on nonaccrual status were 0% and .01% of total loans at December 31, 1997 and
1996, respectively. Nonaccrual loans were .52% of total loans at December 31,
1997 and .31% of total loans at December 31, 1996. There were no loans with
modified terms at December 31, 1997 and 1996. If loans classified as
nonperforming at December 31, 1997 and 1996 had performed in accordance with
their original terms, interest income would not have increased by material
amounts. Income recognized on nonaccrual loans was immaterial for both 1997 and
1996.

            As of September 30, 1998, LaPlace was not aware of any other loans
where known information about possible credit problems of the borrower caused
management to have serious doubts as to the ability of such borrowers to comply
with the loan repayment terms. LaPlace's primary regulators and external
auditors review the loan portfolio as part of their regular examinations and
their assessment of specific credits, based on information available to them at
the time of their examination, may affect the level of LaPlace's nonperforming
loans. Additionally, the loan portfolio is regularly monitored by Senior
Management and the Board. Accordingly, there can be no assurance that other
loans will not be placed on nonaccrual, become 90 days or more past due, or have
terms modified in the future.

            ALLOWANCE FOR LOAN LOSSES. A certain degree of risk is inherent in
the extension of credit. Management has credit policies in place to monitor and
attempt to control the level of loan losses and nonperforming loans. One product
of LaPlace's credit risk management is the maintenance of the allowance for loan
losses at a level considered by management to be adequate to absorb estimated
known and inherent losses in the existing portfolio, including commitments and
standby letters of credit. The allowance for loan losses is established through
charges to operations in the form of provisions for loan losses.

            The allowance is based upon a regular review of current economic
conditions which might affect a borrower's ability to pay, underlying collateral
values, risk in and the composition of the loan portfolio, and prior loss
experience. In addition, LaPlace's primary regulators and external auditors, as
an integral part of their examination process, periodically review LaPlace's
allowance for loan losses and may recommend additions to the allowance based on
their assessment of information available to them at the time of their
examination. Loans that are deemed to be uncollectible are charged-off and
deducted from the allowance. The provision for loan losses and recoveries on
loans previously charged-off are added to the allowance.

            The following table sets forth LaPlace's loan loss experience and
certain information relating to its allowance for loan losses as of the dates
and for the periods indicated.

            The allowance for loan losses was $559,000 or 1.21% of total loans,
$513,000 or 1.15% of total loans, and $443,000 or 1.25% of total loans at
September 30, 1998, December 31, 1997 and December 31, 1996, respectively. Net
charged-off loans during this period were $44,000 during the first nine months
of 1998, compared to $50,000 and $72,000 in 1997 and 1996, respectively. The
allowance for loan losses should not be interpreted as an indication of future
charge-off trends.

            Management believes that the allowance for loan losses at September
30, 1998 is adequate to absorb the known and inherent risks in the loan
portfolio at that time. However, no assurance can be given that future changes
in economic conditions that might adversely affect LaPlace's principal market
area, borrowers or collateral values, and other circumstances will not result in
increased losses in LaPlace's loan portfolio in the future.

            LaPlace's lending activities involve loans with varying degrees of
credit risk. In underwriting residential real estate mortgage loans, LaPlace
evaluates both the borrower's ability to make monthly payments and the value of
the property securing the loan. Most properties securing real estate loans made
by LaPlace are appraised by independent appraisers. LaPlace generally requires
borrowers to obtain an attorney's title opinion and/or title insurance, and fire
and property insurance (including flood insurance, if necessary) in an amount
not less than the amount of the loan. Certain of such loans are sold by LaPlace
in the secondary mortgage market.

            LaPlace's commercial lending activities generally involve
owner-occupied office buildings, equipment financing, and working capital loans.
Such loans may present a slightly higher level of risk than loans secured by
residential real estate. This greater risk is due to several factors, including
the concentration of principal in a limited number of loans and borrowers, and
the effect of general economic conditions. Furthermore, the repayment of
commercial loans is typically dependent upon the successful operation of and
cash flows generated by the borrower's business. If the cash flow from the
business is reduced, the borrower's ability to repay the loan may be impaired.

            LaPlace's construction lending consists principally of interim
construction loans for one-to- four-family residential properties, the permanent
financing for which LaPlace typically sells in the secondary mortgage market. If
sold in the secondary market, underwriting criteria for such loans generally are
the same as the guidelines used by LaPlace for originating permanent residential
mortgage loans. Because of the relatively short (typically six-month) term of
LaPlace's construction loans, such loans are subject to less risk than longer
term construction loans where monitoring of the progress of the project may be
particularly difficult.

            LaPlace offers a variety of consumer loans to individuals. Consumer
loans may entail greater credit risk than do residential mortgage loans,
particularly in the case of consumer loans which are unsecured or are secured by
rapidly depreciable assets, such as automobiles and boats. In such cases, any
repossessed collateral for a defaulted consumer loan may not provide an adequate
source of repayment of the outstanding loan balance as a result of the greater
likelihood of damage or loss or as a result of depreciation. In addition,
consumer loan collections are dependent on the borrower's continuing financial
stability, and thus are more likely to be affected by adverse personal
circumstances. Furthermore, the application of various federal and state laws,
including bankruptcy and insolvency laws, may limit the amount which can be
recovered on such loans.

            LaPlace does not allocate the allowance for loan losses among its
various loan categories. The amount of the allowance should not be interpreted
as an indication of future credit trends or that losses in an amount comparable
to the allowance will occur.

            DEPOSITS. Deposits are the primary source of funding for LaPlace's
earning assets. Total deposits at September 30, 1998 and at December 31, 1997
and 1996 were approximately $55,628,000, $52,709,000, and $49,341,000,
respectively. Time certificates of deposit of $100,000 or more, which were
approximately $4,259,000 at December 31, 1997, had remaining maturities as

         At September 30, 1998, December 31, 1997 and December 31, 1996, LaPlace
had no brokered deposits.

         INTEREST RATE SENSITIVITY. Interest rate risk is the potential impact
of changes in interest rates on net interest income and results from disparities
in repricing opportunities of assets and liabilities over a period of time.
Management estimates the effects of changing interest rates and various balance
sheet strategies on the level of net interest income. Management may alter the
mix of floating- and fixed-rate assets and liabilities, change pricing
schedules, and adjust maturities through sales and purchases of securities
available-for-sale as a means of limiting interest rate risk.

         The degree of interest rate sensitivity is not equal for all types of
assets and liabilities. LaPlace's experience has indicated that the repricing of
interest-bearing demand, savings and money market accounts does not move with
the same magnitude as general market rates. Additionally, these deposit
categories, along with non-interest demand, have historically been stable
sources of funds to LaPlace, which indicates a much longer implicit maturity
than their contractual availability. LaPlace's cumulative gap to total assets at
September 30, 1998 was 10.5% within the three-month period and 1.7% within the
twelve-month period. A positive gap implies that earnings would increase in a
rising interest rate environment and decrease in a falling interest rate
environment.

         LIQUIDITY. LaPlace seeks to manage its liquidity position to attempt to
ensure that sufficient funds are available to meet customers' needs for
borrowing and deposit withdrawals. Liquidity is derived from both the asset and
liability sides of the balance sheet. Asset liquidity arises from the ability to
convert assets to cash and self-liquidation or maturity of assets. Liquid asset
balances include cash, interest-bearing deposits with financial institutions,
short-term investments and federal funds sold. Liability liquidity arises from a
diversity of funding sources as well as from the ability of


                                       77

<PAGE>   87



LaPlace to attract deposits of varying maturities. If LaPlace was limited to
only one source of funding or all its deposits had the same maturity, its
liquidity position would be adversely impacted.

         LaPlace's funding source is primarily its deposit base which is
comprised of interest-bearing and noninterest-bearing accounts, augmented
through federal funds purchased, Federal Home Loan Bank borrowings, and other
short-term borrowings, which are interest-bearing. LaPlace's non-interest
bearing demand deposits are, by their very nature, subject to withdrawal upon
demand. Declines in one form of funding source require LaPlace to obtain funds
from another source. If LaPlace was to experience a decline in
noninterest-bearing demand deposits and was to have a significant increase in
loan volume without a commensurate increase in such deposits, it would utilize
alternative sources of funds, probably at higher cost, to maintain its liquidity
and to meet its loan funding needs. This would place downward pressure on
LaPlace's net interest margin and might have a negative impact on LaPlace's
liquidity position.

         LaPlace's liquidity expressed as a percentage of net liquid assets to
net liabilities was 35.08% and 37.36% at September 30, 1998 and December 31,
1997, respectively.

         CAPITAL ADEQUACY. At September 30, 1998, LaPlace's total shareholders'
equity was $8,263,000, an increase of 11.35% from $7,421,000 at December 31,
1997. Book value per common share is presented in the table below.

         Adequate levels of capital are necessary over time to sustain growth
and absorb losses. In the case of banks and bank holding companies, capital
levels must also meet minimum regulatory requirements. All risk-based and other
capital ratios (which are computed for LaPlace's wholly-owned subsidiary, Bank
of LaPlace) improved from December 31, 1996 to December 31, 1997 and from
December 31, 1997 to September 30, 1998, and remain well above regulatory
minimums. At September 30, 1998, Tier I capital was 16.18% of risk-weighted
assets and total capital was 17.43% of risk-weighted assets, compared to the
regulatory minimums of 4.0% and 8.0%, respectively. Bank of LaPlace's regulatory
leverage ratio, which compares Tier I capital to adjusted total assets, was
10.09% at September 30, 1998, compared to the regulatory minimum of 4.0%. Under
present regulations, Bank of LaPlace was classified as "well capitalized" based
upon its capital ratios at September 30, 1998, December 31, 1997 and December
31, 1996. The following table sets forth Bank of LaPlace's risk based capital

YEAR 2000 COMPLIANCE

         The inability of computers, software and other equipment utilizing
microprocessors to recognize and properly process data fields containing a four
digit year is commonly referred to as the "Year 2000 problem." As the year 2000
approaches, such systems may be unable to accurately process certain date-based
information.

         LaPlace believes it has identified all significant systems that may
require modification to ensure Year 2000 compliance. Internal and external
resources are being used to test Year 2000 compliance and make any required
modifications. The testing of all significant systems by outside hardware and
software suppliers is substantially complete, and several of LaPlace's critical
systems already have been certified by their vendor or third party testing
agencies to be Year 2000 compliant. LaPlace intends to complete the testing of
all significant systems by December 31, 1998 and to implement any required
modifications before June 30, 1999, as required by FDIC guidelines.

<PAGE>   89



        The total cost to LaPlace of Year 2000 compliance activities has not
been and is not anticipated to be material to LaPlace's financial position or
results of operations in any given year. Year 2000 compliance costs and the date
on which LaPlace plans to complete Year 2000 testing and modification processes
are based on management's best estimates, which were derived utilizing numerous
assumptions of future events, including the continued availability of certain
resources, third party modification plans and other factors. There can be no
assurance, however, that these estimates will be achieved and actual results
could differ from those plans.

RECENT ACCOUNTING PRONOUNCEMENTS

        In June 1997, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" ("FAS 130"). FAS 130 establishes standards for reporting
and display of comprehensive income and its components (revenues, expenses,
gains and losses) in a full set of general purpose financial statements. FAS 130
requires that 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 with the same prominence as other financial
statements. LaPlace adopted FAS 130 beginning January 1, 1998. The adoption of
this pronouncement did not have a material impact on the financial statements of
LaPlace.

         Acquisitions have been, and are expected to continue to be, an
important part of the expansion of Union Planters' business. During the period
beginning January 1, 1994 and ending September 30, 1998, Union Planters
completed the acquisition of 43 institutions with approximately $26.4 billion in
total assets. The restated consolidated financial statements of Union Planters
included in Exhibit 99.1 to its September 20, 1998 Quarterly Report on Form 10-Q
and filed with the SEC, and the financial information relating to Union Planters
included under "Selected Financial Data" in this proxy statement-prospectus,
reflect the financial impact of all of such acquisitions, including the
acquisitions completed during 1998.

         In addition, as of September 30, 1998, Union Planters was a party to
definitive agreements to acquire five financial institutions in addition to
LaPlace, and to purchase 56 branch locations and assume deposit liabilities of
approximately $1.8 billion in Indiana (the "Indiana Branch Purchase"


                                       81

<PAGE>   91



   
and, together with all other pending acquisitions, the "Other Pending
Acquisitions"). The Other Pending Acquisitions had aggregate total assets of
approximately $3.5 billion at September 30, 1998. For information with respect
to these acquisitions, see "--Recent Developments" below.
    

         Union Planters expects to continue to take advantage of the
consolidation of the financial services industry by further developing its
franchise through the acquisition of financial institutions. Future acquisitions
may entail the payment by Union Planters of consideration in excess of the book
value of the underlying net assets acquired, may result in the issuance of
additional shares of Union Planters capital stock or the incurring of additional
indebtedness by Union Planters, and could have a dilutive effect on the earnings
or book value per share of Union Planters common stock. Moreover, significant
charges against earnings are sometimes required incidental to acquisitions. For
a description of the acquisitions in addition to the merger which are currently
pending, see "--Recent Developments."

         The principal executive offices of Union Planters are located at 7130
Goodlett Farms Parkway, Memphis, Tennessee 38018, and its telephone number at
such address is (901) 580-6000. Additional information with respect to Union
Planters and its subsidiaries is included in documents incorporated by reference

RECENT DEVELOPMENTS

         RECENT SALE OF CREDIT CARD PORTFOLIO. On October 15, 1998, Union
Planters sold substantially all of its credit card portfolio to MBNA Bank
America, N.A. Union Planters also entered into an agreement with MBNA Bank
America, N.A. to sell it a large majority of the credit card portfolios of Union
Planters Bank of Kentucky, a wholly owned subsidiary of Union Planters, and of
Magna Bank, N.A. which merged into UPB on October 9, 1998. The value of the
credit card portfolio sold totaled $460 million. In the fourth quarter of 1998,
Union Planters expects to recognize a net gain of $65 to $70 million on a pretax
basis and approximately $40 to $43 million after taxes as a result of the sale.
Certain estimated costs related to selling the credit card portfolios, including
employee severance, equipment write-offs and other fees, h ave been netted
against the gain. Union Planters also expects to charge off approximately $10
million to $15 million of credit card receivables that will not be purchased by
MBNA Bank America, N.A. in the fourth quarter of 1998. A smaller portion of the
transaction will settle in the first quarter of 1999.

         RECENTLY COMPLETED ACQUISITIONS. Since December 31, 1997, Union
Planters has completed 14 acquisitions, representing approximately $13.5 billion
in assets. The financial impact of all of such acquisitions deemed material are
reflected in the consolidated financial statements of Union Planters included in
its Exhibit 99.1 to the September 30, 1998 Quarterly Report on Form 10-Q and
filed with the SEC, and in the financial information relating to Union Planters
included under "Summary--Selected Financial Data" in this proxy
statement-prospectus.

         OTHER PENDING ACQUISITIONS. Union Planters has entered into definitive
agreements to acquire the following financial institutions in addition to
LaPlace (collectively, the "Other Pending Acquisitions") which Union Planters'
management considers probable of consummation and which are expected to close in
1998.

FOURTH QUARTER EARNINGS CONSIDERATIONS. It is expected that either Union
Planters or the institutions acquired or to be acquired in connection with the
merger and the Other Pending Acquisitions will incur charges arising from such
acquisitions and from the assimilation of those institutions into the Union
Planters organization. Anticipated charges would normally arise from matters
such as, but not limited to:

     o    legal, accounting, financial advisory and consulting fees;

     o    payment of contractual benefits triggered by a change of control,
          early retirement and involuntary separation and related benefits;

                                       83

<PAGE>   93

     o    costs associated with elimination of duplicate facilities and branch
          consolidations;

     o    data processing charges;

     o    cancellation of vendor contracts; and

     o    other contingencies and similar costs which normally arise from the
          consolidation of operational activities.

         For a discussion of Union Planters' acquisition program and the
significant charges Union Planters has incurred over the past three years
incidental to its acquisition program, see the caption "Acquisitions" on pages
A-3, A-4 and A-5 in Union Planters' restated financial statements filed in Union
Planters' September 30, 1998 Quarterly Report filed on Form 10-Q, and Note 2 to
Union Planters' audited consolidated financial statements for the years ended
December 31, 1997, 1996, and 1995 also contained in Union Planters' September
30, 1998 Quarterly Report filed on Form 10-Q, Exhibit 99.1. Reference is also
made to pages 17,18, 20, and 21 to Union Planters September 30, 1998 Quarterly
Report on Form 10-Q for a discussion of significant charges incurred in the nine
months ended September 30, 1998.

         The merger and the Other Pending Acquisitions (with the exception of
the Indiana Branch Purchase, the Somerset Purchase and the First Mutual
Purchase) are expected to be accounted for as pooling-of-interests. Union
Planters currently estimates incurring aggregate pre-tax and after-tax charges
in the range of $5 million to $6 million in connection with completing the
merger and the Other Pending Acquisitions. Union Planters also expects to incur
expenses of approximately $30 million in the fourth quarter of 1998, both as a
pretax and after-tax basis, primarily in connection with the settlement of
employment agreements related to entities acquired in the third quarter of 1998.
To the extent that Union Planters' recognition of these acquisition-related
charges is contingent upon consummation of a particular transaction, those
charges would be recognized in the period in which such transaction closes. See
"SUMMARY--Historical and Pro Forma Per Share Data".

         The range of anticipated charges to be incurred in connection with
consummating the merger and the Other Pending Acquisitions is a preliminary
estimate of the significant charges which may, in the aggregate, be required and
should be viewed accordingly. Moreover, this range has been based on the due
diligence that has been performed to date in connection with the merger and the
Other Pending Acquisitions. The range may be subject to change, and the actual
charges incurred may be higher or lower than what is currently contemplated,
once the acquired institutions are assimilated from an operational perspective
and various contingencies are either satisfied or eliminated. Furthermore, the
range of anticipated charges will change if additional entities are acquired.
Union Planters regularly evaluates the potential acquisition of, and holds
discussions with, various potential acquisition candidates. As a general rule,
Union Planters will publicly announce such acquisitions only after a definitive
agreement has been reached, and only then if Union Planters considers the
acquisition to be of such a size as to be a significant acquisition. Since the
range of anticipated acquisition-related charges is likely to change with
additional acquisitions, and since Union Planters regularly engages in
acquisitions, such range could change, and you should view such information
accordingly.

         Since September 30, 1998, Union Planters has expensed that portion of
certain restricted stock grants that would otherwise have remained unrecognized
at the recipients earliest possible retirement age. This will have the effect of
increasing benefits expense in the fourth quarter of 1998 by approximately $8.9
million pretax and $5.5 million on an after tax basis. Additionally, in


                                       84

<PAGE>   94



connection with the consolidation of certain loan and deposit functions, Union
Planters is implementing a plan to image all documents related to loans and
deposits. During the fourth quarter of 1998, Union Planters will engage a third
party to image all of its current documents. The total expenses estimated to be
incurred in the fourth quarter of 1998 related to this project is approximately
$4.8 million pretax and $3.29 million on an after tax basis.

         Certain acquisitions during 1998 have significantly increased the
goodwill and other intangible costs to $361 million at September 30, 1998. Given
changing market conditions, primarily interest rate and the related volatility
of the mortgage markets, Union Planters plans to perform a review of the
realization of these intangibles and other related assets such as investment
securities premiums during the fourth quarter of 1998. The impact of this review
cannot be quantified at this time.

                        CERTAIN REGULATORY CONSIDERATIONS

GENERAL

         Union Planters and LaPlace are bank holding companies registered with
the Federal Reserve. As such, Union Planters and LaPlace and their non-bank
subsidiaries are subject to the supervision, examination, and reporting
requirements of the Bank Holding Company Act and the regulations of the Federal
Reserve. The following discussion summarizes the regulatory framework applicable
to banks and bank holding companies and provides certain specific information
related to Union Planters. A more complete discussion is included in Union
Planters' 1997 Annual Report on Form 10-K. See "WHERE YOU CAN FIND MORE
INFORMATION."

         Bank holding companies are required to obtain the prior approval of the
Federal Reserve before they may:

     o    acquire direct or indirect ownership or control of more than 5% of the
          voting shares of any bank;

     o    acquire all or substantially all of the assets of any bank; or

     o    merge or consolidate with any other bank holding company.

         The Federal Reserve generally may not approve any transaction that
would result in a monopoly or that would further a combination or conspiracy to
monopolize banking in the United States. Nor can the Federal Reserve approve a
transaction that could substantially lessen competition in any section of the
country, that would tend to create a monopoly in any section of the country, or
that would be in restraint of trade. But the Federal Reserve may approve any
such transaction if it determines that the public interest in meeting the
convenience and needs of the community served clearly outweigh the
anticompetitive effects of the proposed transaction. The Federal Reserve is also
required to consider the financial and managerial resources and future prospects
of the bank holding companies and banks concerned, as well as the convenience
and needs of the community to be served. Consideration of financial resources
generally focuses on capital adequacy, which is discussed below. And
consideration of convenience and needs includes the parties' performance under
the Community Reinvestment Act of 1977.




                                       85

<PAGE>   95



         Another factor that is gaining increasing scrutiny in the application
process is the Year 2000 readiness of the parties involved in acquisition
transactions. Banking organizations whose Year 2000 readiness is in less than
satisfactory condition are undergoing special scrutiny in connection with
acquisition transactions requiring regulatory approval, and may not be eligible
to use expedited application procedures for acquisition transactions.

         Under the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 ("Interstate Banking Act"), Union Planters and any other bank holding
company may now acquire a bank located in any state, subject to certain
deposit-percentage limitations, aging requirements, and other restrictions. The
Interstate Banking Act also generally permits a bank to branch interstate
through acquisitions of banks in other states. By adopting legislation prior to
June 1, 1997, a state had the ability either to "opt in" and accelerate the date
after which interstate branching is permissible or "opt out" and prohibit
interstate branching altogether. Texas, where Union Planters recently completed
an acquisition, elected to "opt out," in legislation that expires September 2,
1999. Union Planters has used the Interstate Banking Act to merge substantially
all of Union Planters' banking subsidiaries with and into Union Planters Bank,
National Association. As a result, that bank is now a multi-state national bank
with branches in Alabama, Arkansas, Florida, Illinois, Indiana, Iowa, Kentucky,
Louisiana, Mississippi, Missouri, and Tennessee.

         The Bank Holding Company Act prohibits Union Planters from:

         (1)  engaging in activities other than banking, managing, or 
              controlling banks or other permissible subsidiaries; and

         (2)  acquiring or retaining direct or indirect control of any company
              engaged in any activities other than those activities determined 
              by the Federal Reserve to be so closely related to banking or 
              managing or controlling banks as to be a proper incident thereto.

   In determining whether a particular activity is permissible, the Federal
Reserve must consider whether the performance of such an activity reasonably can
be expected to produce benefits to the public that outweigh possible adverse
effects. Possible benefits the Federal Reserve considers include greater
convenience, increased competition, or gains in efficiency. Possible adverse
effects include undue concentration of resources, decreased or unfair
competition, conflicts of interest, or unsound banking practices. The Federal
Reserve has determined the following to be permissible activities of bank
holding companies:

     o    factoring accounts receivable,

     o    acquiring or servicing loans,

     o    easing personal property,

     o    conducting discount securities brokerage activities,

     o    performing certain data processing services,

     o    acting as agent or broker in selling credit life insurance and certain
          other types of insurance in connection with credit transactions, and



                                       86

<PAGE>   96



         o    performing certain insurance underwriting activities.

         There are no territorial limitations on permissible non-banking
activities of bank holding companies. Despite prior approval, the Federal
Reserve has the power to order a holding company or its subsidiaries to
terminate any activity or to terminate its ownership or control of any
subsidiary when it has reasonable cause to believe that a serious risk to the
financial safety, soundness, or stability of any bank subsidiary of that bank
holding company may result from such activity.

         The banks owned by Union Planters are members of the FDIC. Their
deposits are insured by the FDIC to the extent provided by law. Each bank is
also subject to numerous state and federal statutes and regulations that affect
its business, activities, and operations, and each is supervised and examined by
one or more state or federal bank regulatory agencies.

         The FDIC and the applicable state authority in the case of
state-chartered nonmember banks, the Office of Thrift Supervision ("OTS") in the
case of federally chartered thrift institutions, the Federal Reserve in the case
of state-chartered member banks, and the Office of the Comptroller of the
Currency ("OCC") in the case of national banks supervise the subsidiaries of
Union Planters and LaPlace and regularly examine the operations of such
institutions. They have authority to approve or disapprove mergers,
consolidations, the establishment of branches, and similar corporate actions.
The federal and state banking regulators also have the power to prevent the
continuance or development of unsafe or unsound banking practices or other
violations of law.

         PAYMENT OF DIVIDENDS

         Union Planters is a legal entity separate and distinct from its
banking, thrift, and other subsidiaries. The principal sources of cash flow of
Union Planters, including cash flow to pay dividends to its shareholders, are
dividends from its subsidiary depository institutions. There are statutory and
regulatory limitations on the payment of dividends by these subsidiary
depository institutions to Union Planters, as well as by Union Planters and
LaPlace to their shareholders.

         As to the payment of dividends, each of Union Planters' state-chartered
banking subsidiaries is subject to the laws and regulations of the state in
which the bank is located, and to the regulations of the bank's primary federal
regulator. Union Planters' subsidiaries that are thrift institutions are subject
to the OTS' capital distributions regulations, and those that are national banks
are subject to the regulations of the OCC.

         If the federal banking regulator determines that a depository
institution under its jurisdiction is engaged in or is about to engage in an
unsafe or unsound practice, the regulator may require, after notice and hearing,
that the institution cease and desist from such practice. Depending on the
financial condition of the depository institution, an unsafe or unsound practice
could include the payment of dividends. The federal banking agencies have
indicated that paying dividends that deplete a depository institution's capital
base to an inadequate level would be an unsafe and unsound banking practice.
Under the Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA"), a depository institution may not pay any dividend if 


                                       87

<PAGE>   97



payment would cause it to become undercapitalized or if it already is
undercapitalized. See "--Prompt Corrective Action." The federal agencies have
also issued policy statements that provide that bank holding companies and
insured banks should generally only pay dividends out of current operating
earnings.

         At September 30,1998, under dividend restrictions imposed under federal
and state laws, Union Planters' banking subsidiaries, without obtaining
governmental approvals, could declare aggregate dividends to Union Planters of
approximately $119 million.

         The payment of dividends by Union Planters and its bank subsidiaries
may also be affected or limited by other factors, such as the requirement to
maintain adequate capital above regulatory guidelines.

         CAPITAL ADEQUACY

         Union Planters and its banking subsidiaries are required to comply with
the capital adequacy standards established by the Federal Reserve in the case of
Union Planters, and the appropriate federal banking regulator in the case of
each Union Planters bank. There are two basic measures of capital adequacy for
bank holding companies and the depository institutions that they own: a
risk-based measure and a leverage measure. All applicable capital standards must
be satisfied for a bank holding company to be considered in compliance.

         The risk-based capital standards are designed to make regulatory
capital requirements more sensitive to differences in risk profile among
depository institutions and bank holding companies, to account for
off-balance-sheet exposure, and to minimize disincentives for holding liquid
assets. Assets and off-balance-sheet items are assigned to broad risk
categories, each with appropriate weights. The resulting capital ratios
represent capital as a percentage of total risk-weighted assets and
off-balance-sheet items.

         The minimum guideline for the ratio ("Total Capital Ratio") of total
capital ("Total Capital") to risk-weighted assets (including certain
off-balance-sheet items, such as standby letters of credit) is 8.0%. At least
half of Total Capital must be composed of common equity, undivided profits,
minority interests in the equity accounts of consolidated subsidiaries,
noncumulative perpetual preferred stock, and a limited amount of cumulative
perpetual preferred stock, less goodwill and certain other intangible assets
("Tier 1 Capital"). The remainder may consist of subordinated debt, other
preferred stock, and a limited amount of loan loss reserves ("Tier 2 Capital").
At September 30, 1998, Union Planters' consolidated Total Capital Ratio and its
Tier 1 Capital Ratio (i.e., the ratio of Tier 1 Capital to risk-weighted assets)
were 17.07% and 13.49%, respectively.

         In addition, the Federal Reserve has established minimum leverage
ratio guidelines for bank holding companies. These guidelines provide for a
minimum ratio (the "Leverage Ratio") of Tier 1 Capital to average assets, less
goodwill and certain other intangible assets, of 3.0% for bank holding companies
that meet certain specified criteria, including having the highest regulatory
rating. All other bank holding companies generally are required to maintain a
Leverage Ratio of at least 3.0%, plus an additional cushion of 100 to 200 basis
points. Union Planters' Leverage


                                       88

<PAGE>   98



Ratio at September 30, 1998, was 9.29%. The guidelines also provide that bank
holding companies that experience internal growth or make acquisitions will be
expected to maintain strong capital positions substantially above the minimum
supervisory levels without significant reliance on intangible assets. The
Federal Reserve will consider a "tangible Tier 1 Capital Leverage Ratio"
(deducting all intangibles) and other indicia of capital strength in evaluating
proposals for expansion or new activities.

         Each of the Union Planters' banks is subject to risk-based and leverage
capital requirements adopted by its federal banking regulator. Those
requirements are similar to those adopted by the Federal Reserve for bank
holding companies. Banking regulators may establish higher capital requirements
for a particular institution based upon the institution's risk profile
including, without limitation, exposure to interest rate risk. Each of Union
Planters' banks was in compliance with those minimum capital requirements as of
September 30, 1998. No federal banking agency has advised Union Planters or its
bank subsidiaries of any specific minimum capital ratio requirement applicable
to it.

         A bank or thrift that fails to meet its capital guidelines may be
subject to a variety of enforcement remedies and certain other restrictions on
its business. Remedies could include the issuance of a capital directive, the
termination of deposit insurance by the FDIC, and a prohibition on the taking of
brokered deposits. As described below, substantial additional restrictions can
be imposed upon FDIC-insured depository institutions that fail to meet their
capital requirements. See "--Prompt Corrective Action."

         The federal bank regulators continue to indicate their desire to raise
the capital requirements that apply to banks beyond their current levels. The
Federal Reserve, the FDIC, and the OCC have proposed an amendment to the
risk-based capital standards that would calculate the change in a bank's net
economic value attributable to increases and decreases in market interest rates
and would require banks with excessive interest rate risk exposure to hold
additional amounts of capital against such exposures. The OTS has already
included an interest-rate risk component in its risk-based capital guidelines
for savings associations that it regulates.

  SUPPORT OF SUBSIDIARY INSTITUTIONS

         Under Federal Reserve policy, Union Planters is expected to act as a
source of financial strength for, and commit its resources to support, each
Union Planters bank. This support may be required at times when Union Planters
may not be inclined to provide it. In addition, any capital loans by a bank
holding company to any of its bank subsidiaries are subordinate to the payment
of deposits and to certain other indebtedness. In the event of a bank holding
company's bankruptcy, any commitment by the bank holding company to a federal
bank regulatory agency to maintain the capital of a bank subsidiary will be
assumed by the bankruptcy trustee and entitled to a priority of payment.

         A depository institution insured by the FDIC can be held liable for any
loss incurred by, or reasonably expected to be incurred by, the FDIC in
connection with the default of a commonly controlled FDIC-insured depository
institution or any assistance provided by the FDIC to any commonly controlled
FDIC-insured depository institution "in danger of default." "Default" is


                                       89

<PAGE>   99

defined generally as the existence of certain conditions indicating that a
default is likely to occur in the absence of regulatory assistance. The FDIC's
claim for damages is superior to claims of shareholders of the insured
depository institution or its holding company, but is subordinate to claims of
depositors, secured creditors, and holders of subordinated debt (other than
affiliates) of the commonly controlled insured depository institution. Union
Planters' banks are subject to these cross-guarantee provisions. As a result,
any loss suffered by the FDIC in respect of any of Union Planters' banks would
likely result in assertion of the cross-guarantee provisions, the assessment of
estimated losses against Union Planters' banking or thrift affiliates, and a
potential loss of Union Planters' investments in its other banks.

PROMPT CORRECTIVE ACTION

               FDICIA establishes a system of prompt corrective action to
resolve the problems of undercapitalized institutions. Under this system, which
became effective in December 1992, the federal banking regulators are required
to establish five capital categories (well capitalized, adequately capitalized,
undercapitalized, significantly undercapitalized, and critically
undercapitalized). With respect to institutions in the three undercapitalized
categories, the regulators must take certain supervisory actions, and are
authorized to take other discretionary actions. The severity of the actions
will depend upon the capital category in which the institution is placed.
Generally, subject to a narrow exception, FDICIA requires the banking regulator
to appoint a receiver or conservator for an institution that is critically
undercapitalized. The federal banking agencies have specified the relevant
capital level for each category.

               An institution is deemed to be well capitalized if it

               -              has a Total Capital Ratio of 10% or greater,
               -              has a Tier 1 Capital Ratio of 6.0% or greater,
               -              has a Leverage Ratio of 5.0% or greater, and
               -              is not subject to any written agreement, order, 
                              capital directive, or prompt corrective action 
                              directive issued by its federal banking agency

               An institution is considered to be adequately capitalized if it 
               has

               -              a Total Capital Ratio of 8.0% or greater,
               -              a Tier 1 Capital Ratio of 4.0% or greater, and
               -              a Leverage Ratio of 4.0% or greater.

               A depository institution is considered to be undercapitalized if 
               it has

               -              a Total Capital Ratio of less than 8.0%, 
               -              a Tier 1 Capital Ratio of less than 4.0%, or 
               -              a Leverage Ratio of less than 4.0%.

               A depository institution is considered to be significantly 
               undercapitalized if it has

               -              a Total Capital Ratio of less than 6.0%,


                                      90
<PAGE>   100

               -              a Tier 1 Capital Ratio of less than 3.0%, or
               -              a Leverage Ratio of less than 3.0%.

               An institution that has a tangible equity capital to assets
ratio equal to or less than 2.0% is deemed to be critically undercapitalized.
"Tangible equity" includes core capital elements counted as Tier 1 Capital for
purposes of the risk-based capital standards, plus the amount of outstanding
cumulative perpetual preferred stock (including related surplus), minus all
intangible assets, with certain exceptions. A depository institution may be
deemed to be in a capitalization category that is lower than is indicated by
its actual capital position if it receives an unsatisfactory examination
rating.

               An institution that is categorized as undercapitalized,
significantly undercapitalized, or critically undercapitalized is required to
submit an acceptable capital restoration plan to its appropriate federal
banking agency. In addition, a bank holding company must guarantee that a
subsidiary bank meet its capital restoration plan. This obligation to fund a
capital restoration plan is limited to the lesser of 5.0% of an
undercapitalized subsidiary's assets or the amount required to meet regulatory
capital requirements. Except in accordance with an accepted capital restoration
plan or with the approval of the FDIC, an undercapitalized institution is also
generally prohibited from increasing its average total assets, making
acquisitions, establishing any branches, or engaging in any new line of
business. In addition, its federal banking agency is given authority with
respect to any undercapitalized institution to take any of the actions it is
required to or may take with respect to a significantly undercapitalized
institution if it determines "that those actions are necessary to carry out the
purpose" of FDICIA.

               For those institutions that are significantly undercapitalized
or undercapitalized and either fail to submit an acceptable capital restoration
plan or fail to implement an approved capital restoration plan, its federal
banking agency must require the institution to:

               (1)           sell enough shares, including voting shares, to
                             become adequately capitalized;

               (2)           merge with (or be sold to) another institution (or 
                             holding company), but only if grounds exist for 
                             appointing a conservator or receiver;

               (3)           restrict certain transactions with its banking 
                             affiliates;

               (4)           restrict transactions with bank or non-bank 
                             affiliates;

               (5)           restrict interest rates that the institution pays
                             on deposits to "prevailing rates" in the
                             institution's "region;"

               (6)           restrict asset growth or reduce total assets;

               (7)           alter, reduce, or terminate activities;

               (8)           hold a new election of directors;

               (9)           dismiss any director or senior executive officer 
                             who held office for more than 180 days immediately 
                             before the institution became undercapitalized, 
                             provided that in requiring dismissal of a director 
                             or senior officer, the agency must comply with
                             certain procedural requirements, including the
                             opportunity for an appeal in which


                                      91
<PAGE>   101



                             the director or officer will have the burden of 
                             proving his or her value to the institution;

               (10)          employ "qualified" senior executive officers;

               (11)          cease accepting deposits from correspondent 
                             depository institutions;

               (12)          divest certain nondepository affiliates which pose
                             a danger to the institution; or

               (13)          be divested by a parent holding company.  In
                             addition, without the prior approval of its federal
                             banking agency, a significantly undercapitalized 
                             institution may not pay any bonus to any senior
                             executive officer or increase the rate of 
                             compensation for such an officer.


                  DESCRIPTION OF UNION PLANTERS CAPITAL STOCK

               Union Planters' charter currently authorizes the issuance of
300,000,000 shares of Union Planters common stock and 10,000,000 shares of
Union Planters Preferred Stock. On October 31, 1998, 136,063,035 shares of
Union Planters common stock were outstanding and approximately 11,819,841
shares were earmarked for issuance in connection with currently outstanding
Union Planters options, Union Planters' dividend reinvestment plan, two small
convertible debt issues, and with respect to conversion rights of currently
outstanding Union Planters Series E preferred stock. In addition, as of October
31, 1998, 968,865 shares of Union Planters' 8% Cumulative, Convertible Series E
preferred stock, were outstanding. On October 31, 1998, none of Union Planters'
750,000 authorized shares of Series A preferred stock were issued and
outstanding nor is management aware of the existence of circumstances from
which it may be inferred that such issuance is imminent. THE CAPITAL STOCK OF
UNION PLANTERS DOES NOT REPRESENT OR CONSTITUTE A DEPOSIT ACCOUNT AND IS NOT
INSURED BY THE FDIC, THE BANK INSURANCE FUND, THE SAVINGS ASSOCIATION INSURANCE
FUND, OR ANY GOVERNMENTAL AGENCY.

UNION PLANTERS COMMON STOCK

               GENERAL. Shares of Union Planters common stock may be issued at
such time or times and for such consideration (not less than the par value
thereof) as the Union Planters board of directors may deem advisable, subject
to such limitations as may be set forth in the laws of the State of Tennessee,
Union Planters' charter or bylaws or the rules of the NYSE. Union Planters
Bank, N.A., a wholly owned, first-tier subsidiary of Union Planters, is the
Registrar, Transfer Agent and Dividend Disbursing Agent for shares of Union
Planters common stock. Its address is Union Planters Bank, National Association
Corporate Trust Department,1 South Church Street, Belleville, Illinois 62220.

               DIVIDENDS. Subject to the preferential dividend rights
applicable to outstanding shares of the Union Planters preferred stock and
subject to applicable requirements, if any, with respect to the setting aside
of sums for purchase, retirement, or sinking funds, if any, for all outstanding
Union Planters preferred stock, the holders of the Union Planters common stock
are entitled to


                                      92
<PAGE>   102

receive, to the extent permitted by law, only such dividends as may be declared
from time to time by the Union Planters board of directors.

               Union Planters has the right to, and may from time to time, enter
into borrowing arrangements or issue other debt instruments, the provisions of
which may contain restrictions on payment of dividends and other distributions
on Union Planters common stock and Union Planters preferred stock. Union
Planters has no such arrangements in effect at the date hereof. In December
1996, Union Planters caused to be issued $200,000,000 in aggregate liquidation
amount of 8.20% Capital Trust Pass-through Securities ("Union Planters Capital
Securities") through a Delaware trust subsidiary. Pursuant to the terms of the
governing instruments, Union Planters would be prohibited from paying dividends
on any Union Planters common stock or Union Planters preferred stock if all
quarterly payments on the Union Planters Capital Securities had not been paid
in full. The Union Planters Capital Securities mature in 2026 and may be
redeemed under certain circumstances prior to maturity.

               LIQUIDATION RIGHTS. In the event of the voluntary or involuntary
liquidation, dissolution, distribution of assets, or winding-up of Union
Planters, after distribution in full of the preferential amounts required to be
distributed to the holders of Union Planters preferred stock, holders of Union
Planters common stock will be entitled to receive all of the remaining assets
of Union Planters, of whatever kind, available for distribution to shareholders
ratably in proportion to the number of shares of Union Planters common stock
held. The Union Planters board of directors may distribute in kind to the
holders of Union Planters common stock such remaining assets of Union Planters
or may sell, transfer, or otherwise dispose of all or any part of such
remaining assets to any other person or entity and receive payment therefor in
cash, stock, or obligations of such other person or entity, and may sell all or
any part of the consideration so received and distribute any balance thereof in
kind to holders of Union Planters common stock. Neither the merger or
consolidation of Union Planters into or with any other corporation, nor the
merger of any other corporation into Union Planters, nor any purchase or
redemption of shares of stock of Union Planters of any class, shall be deemed
to be a dissolution, liquidation, or winding-up of Union Planters for purposes
of this paragraph.

               Because Union Planters is a holding company, its right and the
rights of its creditors and shareholders, including the holders of Union
Planters preferred stock and Union Planters common stock, to participate in the
distribution of assets of a subsidiary on its liquidation or recapitalization
may be subject to prior claims of such subsidiary's creditors except to the
extent that Union Planters itself may be a creditor having recognized claims
against such subsidiary.

               For a further description of Union Planters common stock, see 
"EFFECT OF THE MERGER ON RIGHTS OF SHAREHOLDERS."

UNION PLANTERS PREFERRED STOCK

               SERIES A PREFERRED STOCK. Union Planters' charter provides for 
the issuance of up to 750,000 shares (subject to adjustment by action of the
Union Planters board of directors) of Series


                                      93
<PAGE>   103

A preferred stock under certain circumstances involving a potential change in
control of Union Planters. None of such shares are outstanding and management
is aware of no facts suggesting that issuance of such shares may be imminent.
The Series A preferred stock is described in more detail in Union Planters'
registration statement on Form 8-A, dated January 19, 1989, and filed February
1, 1989 (SEC File No. 0-6919) which is incorporated by reference herein.

               SERIES E PREFERRED STOCK. As of October 31, 1998, 968,865 shares
of Series E preferred stock were outstanding. All shares of Series E preferred
stock have a stated value of $25.00 per share. Dividends are payable at the
rate of $0.50 per share per quarter and are cumulative. The Series E preferred
stock is convertible at the rate of 1.25 shares of Union Planters common stock
for each share of Series E preferred stock. The Series E preferred stock is not
subject to any sinking fund provisions and has no preemptive rights. Such
shares have a liquidation preference of $25.00 per share plus unpaid dividends
accrued thereon and, at Union Planters' option and with the prior approval of
the Federal Reserve, are subject to redemption by Union Planters at any time at
a redemption price of $25.00 per share plus any unpaid dividends accrued
thereon. Holders of Series E preferred stock have no voting rights except as
required by law and in certain other limited circumstances. See "CERTAIN
REGULATORY CONSIDERATIONS -- Payment of Dividends."


                                 OTHER MATTERS

               As of the date of this proxy statement-prospectus, LaPlace 's
board of directors knows of no matters that will be presented for consideration
at the special meeting other than as described in this proxy
statement-prospectus. However, if any other matters properly come before the
special meeting or any adjournment or postponement of the special meeting and
are voted upon, the enclosed proxy will be deemed to confer discretionary
authority to the individuals named as proxies to vote the shares represented by
such proxy as to any such matters.


                             SHAREHOLDER PROPOSALS

   
               Union Planters expects to hold its next annual meeting of
shareholders in April 1999, after the merger. Under SEC rules, proposals of
Union Planters shareholders intended to be presented at that meeting must be

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER (this "Agreement") is made and
entered into as of July 1, 1998, by and between LaPlace Bancshares, Inc., a
Louisiana corporation having its principal office located in LaPlace, Louisiana
("Subject Company"), Union Planters Holding Corporation, a Tennessee corporation
having its principal office located in Memphis, Tennessee ("Merger Subsidiary"),
and joined in by Union Planters Corporation, a Tennessee corporation having its
principal office located in Memphis, Tennessee ("Parent").

                                    PREAMBLE

         The Board of Directors of each of Subject Company, Merger Subsidiary
and Parent is of the opinion that the transactions described herein are in the
best interests of such Party and its respective shareholders. This Agreement and
the Plan of Merger attached hereto at Exhibit 1 and incorporated herein by
reference provide for the acquisition of Subject Company by Parent pursuant to
the merger of Subject Company with and into Merger Subsidiary. At the Effective
Time, the outstanding shares of the common stock of Subject Company shall be
converted into the right to receive shares of the common stock of Parent (except
as provided in Sections 3.1, 3.3 and 3.4 of this Agreement). As a result,
shareholders of Subject Company shall become shareholders of Parent, and
Surviving Corporation shall continue to conduct its business and operations as a
wholly-owned subsidiary of Parent. The transactions described in this Agreement
are subject to the approvals of the shareholders of Subject Company, the FRB,
the LOFI, and other applicable federal and state regulatory authorities, and the
satisfaction of certain other conditions described in this Agreement. It is the
intention of the parties to this Agreement that (i) for federal income tax
purposes this Agreement shall constitute a plan of merger and the Merger shall
qualify as a "reorganization" within the meaning of Section 368(a) of the
Internal Revenue Code and (ii) for accounting purposes the Merger shall qualify
for treatment as a pooling-of-interests.

         Certain terms used in this Agreement are defined in Section 11.1 of
this Agreement.

         NOW, THEREFORE, in consideration of the above and the mutual
warranties, representations, covenants, and agreements set forth herein, the
parties agree as follows:

         1.1 Merger. Subject to the terms and conditions of this Agreement and
the Plan of Merger, at the Effective Time, Subject Company shall be merged with

         1.2 Time and Place of Closing. The Closing will take place at 9:00 A.M.

practicable, but in no event later than 30 days following the last to occur of

having authority over and approving or exempting the Merger (taking into account
any requisite waiting period in respect thereof), (ii) the date on which the

         1.4 Restructure of Transaction. Parent shall, in its reasonable
discretion, have the unilateral right to revise the structure of the Merger
contemplated by this Agreement in order to achieve tax benefits or for any other
reason which Parent may deem advisable; provided, however, that Parent shall not
have the right, without the approval of the Board of Directors of Subject
Company and, if required by the LBCL, the holders of the Subject Company Common
Stock, to make any revision to the structure of the Merger which: (i) changes
the amount of the consideration which the holders of shares of Subject Company
Common Stock are entitled to receive (determined in the manner provided in
Section 3.1 of this Agreement); (ii) changes the intended tax free effects of
the Merger to Parent, Subject Company or the holders of shares of Subject
Company Common Stock; (iii) would permit Parent to pay the consideration other
than by delivery of Parent Common Stock registered with the SEC (in the manner
described in Section 4.1 of this Agreement); (iv) would be adverse to the
interests of Subject Company or adverse to the holders of shares of Subject
Company Common Stock; (v) would impede or delay consummation of the Merger by
more than 30 days; or (vi) would require a vote of Parent's shareholders under
relevant state Law. Parent may exercise this right of revision by giving written
notice to Subject Company in the manner provided in Section 11.8 of this
Agreement which notice shall be in the form of an amendment to this Agreement
and the Plan of Merger or in the form of an Amended and Restated Agreement and
Plan of Merger.

persons as may thereafter be elected, shall serve as the directors of the

                           MANNER OF CONVERTING SHARES


         3.1 Conversion of Shares. Subject to the provisions of this Article 3
(and Article 3 of the Plan of Merger), at the Effective Time, by virtue of the
Merger and without any action on the part of Parent, Merger Subsidiary, Subject
Company, or the shareholders of any of the foregoing, the shares of the
constituent corporations shall be converted as follows:

                  (a) Each share of Parent Capital Stock, including any
associated Parent Rights, issued and outstanding immediately prior to the
Effective Time shall remain issued and outstanding from and after the Effective
Time.


                  LaPlace Bancshares - Merger Agreement Page 2


<PAGE>   113






                  (b) Each share of Merger Subsidiary Common Stock issued and
outstanding immediately prior to the Effective Time shall remain issued and
outstanding and shall represent one share of common stock of the Surviving
Corporation from and after the Effective Time.

                  (c) Except for Dissenting Shares, each share of Subject
Company Common Stock, (excluding shares held by Subject Company, any Subject
Company Subsidiary, Parent or any Parent Subsidiary, in each case other than in
a fiduciary capacity or as a result of debts previously contracted) issued and
outstanding at the Effective Time shall cease to be outstanding and shall be
converted into and exchanged for the right to receive 2.83 shares of Parent
Common Stock (subject to possible adjustment as set forth in Section 3.2 of this
Agreement, the "Exchange Ratio"). [exchange ratio to be determined by dividing
the average closing price for UPC Common Stock for the 20 trading days
immediately preceding the date this merger agreement is executed into $159.88]
Pursuant to the Parent Rights Agreement, each share of Parent Common Stock
issued in connection with the Merger upon conversion of Subject Company Common
Stock shall be accompanied by a Parent Right.

                  (d) Dissenting Shares shall not be converted pursuant to
Section 3.1(c) in the Merger but, at and after the Effective Time, shall
represent only the right to receive payment in accordance with the applicable
provisions of Section 131 of the LBCL. If a holder of Dissenting Shares becomes
ineligible for payment under Section 131 of the LBCL, then such holder's
Dissenting Shares shall cease to be Dissenting Shares and shall be converted in
the manner set forth in Section 3.1(c) effective as of the Effective Time.

         3.2 Anti-Dilution Provisions. In the event Parent changes the number of
shares of Parent Common Stock issued and outstanding after the date of this
Agreement and prior to the Effective Time as a result of a stock split, stock
dividend, subdivision, reclassification, conversion or similar recapitalization
with respect to such stock and the record date therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split,
subdivision, reclassification, conversion or similar recapitalization for which
a record date is not established) shall be prior to the Effective Time, the
Exchange Ratio shall be proportionately adjusted.

         3.3 Shares Held by Subject Company or Parent. Each of the shares of
Subject Company Common Stock held by Subject Company, any Subject Company
Subsidiary, Parent or any Parent Subsidiary, in each case other than in a
fiduciary capacity or as a result of debts previously contracted, shall be
canceled and retired at the Effective Time and no consideration shall be issued
in exchange therefor.

         3.4 Fractional Shares. Notwithstanding any other provision of this
Agreement, each holder of shares of Subject Company Common Stock exchanged
pursuant to the Merger who would otherwise have been entitled to receive a
fractional share of Parent Common Stock (after taking into account all
certificates delivered by such holder which, immediately prior to the Effective
Time, represented shares of Subject Company Common Stock (each a "Subject
Company Certificate")) shall receive, in lieu thereof, cash (without interest)
in an amount equal to such fractional share of Parent Common Stock multiplied by
the closing price of Parent Common Stock on the NYSE- Composite Transactions
List (as reported by The Wall Street Journal or, if not reported thereby, any
other authoritative source reasonably selected by Parent) on the last trading
day preceding the Effective Time. No such holder will be entitled to dividends,
voting rights, or any other rights as a shareholder in respect of any fractional
shares.

                                    ARTICLE 4
                               EXCHANGE OF SHARES

         4.1 Exchange Procedures. As soon as reasonably practicable, after the
Effective Time, Parent and Subject Company shall cause the exchange agent
selected by Parent (the "Exchange Agent") to mail to each holder of record of a
Subject Company Certificate appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
Subject Company Certificates shall pass, only upon proper delivery of such
Subject Company Certificates to the Exchange Agent). Subject Company shall have
the right to review and approve the transmittal materials. The Exchange Agent
may establish reasonable and customary rules and procedures


                  LaPlace Bancshares - Merger Agreement Page 3


<PAGE>   114



in connection with its duties, provided such rules and procedures do not have
the effect of unreasonably delaying or limiting or eliminating the obligation of
Parent and/or Merger Subsidiary to deliver the consideration contemplated by
Article 3 of this Agreement. After the Effective Time, each holder of shares of
Subject Company Common Stock (other than Dissenting Shares or shares to be
canceled pursuant to Section 3.3 of this Agreement) issued and outstanding at
the Effective Time shall surrender the certificate or certificates representing
such shares to the Exchange Agent and shall promptly upon surrender thereof
receive in exchange therefor the consideration provided in Section 3.1(c) of
this Agreement, together with all undelivered dividends and other distributions,
if any, in respect of such shares (without interest thereon) pursuant to Section
4.2 of this Agreement. To the extent required by Section 3.4 of this Agreement,
each holder of shares of Subject Company Common Stock issued and outstanding at
the Effective Time also shall receive, upon surrender of the certificate or
certificates representing such shares, cash in lieu of any fractional share of
Parent Common Stock to which such holder may be otherwise entitled (without
interest). Parent shall not be obligated to deliver the consideration to which
any former holder of Subject Company Common Stock is entitled as a result of the
Merger until such holder surrenders such holder's Subject Company Certificates
for exchange as provided in this Section 4.1 or in Section 4.2 of this
Agreement. The Subject Company Certificates so surrendered shall be duly
endorsed as the Exchange Agent may reasonably require. Any other provision of
this Agreement notwithstanding, neither Parent, Merger Subsidiary nor the
Exchange Agent shall be liable to a holder of Subject Company Common Stock for
any amounts paid or property delivered in good faith to a public official
pursuant to any applicable abandoned property Law.

         4.2 Rights of Former Subject Company Shareholders. At the Effective
Time, the stock transfer books of Subject Company shall be closed as to holders
of Subject Company Common Stock immediately prior to the Effective Time and no
transfer of Subject Company Common Stock by any such holder shall thereafter be
made or recognized. Until surrendered for exchange in accordance with the
provisions of Section 4.1 of this Agreement, each certificate theretofore
representing shares of Subject Company Common Stock (other than Dissenting
Shares or shares to be canceled pursuant to Section 3.3 of this Agreement) shall
from and after the Effective Time represent for all purposes only the right to
receive the consideration provided in Sections 3.1(c) and 3.4 of this Agreement
in exchange therefor, subject, however, to the Surviving Corporation's
obligations to pay any dividends or make any other distributions with a record
date prior to the Effective Time which have been declared or made by Subject
Company in respect of such shares of Subject Company Common Stock in accordance
with the terms of this Agreement and which remain unpaid at the Effective Time.
In addition, whenever a dividend or other distribution is declared by Parent on
the Parent Common Stock, the record date for which is at or after the Effective
Time, the declaration shall include dividends or other distributions on all
shares of Parent Common Stock issuable pursuant to this Agreement, but no
dividend or other distribution payable to the holders of record of Parent Common
Stock as of any time subsequent to the Effective Time shall be delivered to the
holder of any certificate representing shares of Subject Company Common Stock
issued and outstanding at the Effective Time until such holder surrenders such
certificate for exchange as provided in Section 4.1 of this Agreement. However,
upon surrender of such Subject Company Common Stock certificate, both a Parent
Common Stock certificate and any undelivered dividends and other distributions
payable hereunder (without interest) shall be delivered and paid with respect to
each share represented by such certificate. In the event any Subject Company
Common Stock 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 reasonably required by Parent, the posting
by such person of a bond in such amount as Parent may reasonably direct as
indemnity against any claim that may be made against it with respect to such
certificate, the Exchange Agent shall issue in exchange for such lost, stolen or
destroyed certificate the shares of Parent Common Stock and cash in lieu of
fractional shares and dividends and other distributions deliverable in respect
thereof pursuant to this Agreement.

                                    ARTICLE 5

                REPRESENTATIONS AND WARRANTIES OF SUBJECT COMPANY

                  LaPlace Bancshares - Merger Agreement Page 4




<PAGE>   115





         5.1 Organization, Standing, and Power. Subject Company is a corporation
duly organized, validly existing, and in good standing under the Laws of the
State of Louisiana, and has the corporate power and authority to carry on its
business as now conducted and to own, lease, and operate its Assets. Subject
Company is duly qualified or licensed to transact business as a foreign
corporation in good standing in each of the States of the United States and in
each foreign jurisdiction where the character of its Assets or the nature or
conduct of its business requires it to be so qualified or licensed, except for
such jurisdictions in which the failure to be so qualified or licensed is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Subject Company.

         5.2 Authority; No Breach by Agreement. (a) Subject Company has the
corporate power and authority necessary to execute, deliver, and perform its
obligations under this Agreement and the Plan of Merger and to consummate the
transactions contemplated hereby and thereby. The execution, delivery, and
performance of this Agreement and the Plan of Merger, and the consummation of
the transactions contemplated herein and therein, including the Merger, have
been duly and validly authorized by all necessary corporate action in respect
thereof on the part of Subject Company, subject to the approval of this
Agreement and the Plan of Merger by the holders of the number of outstanding
shares of Subject Company Common Stock required by the LBCL, which is the only
shareholder vote required for approval of this Agreement and consummation of the
Merger by Subject Company. Subject to such requisite shareholder approval, the
receipt of all Consents required from Regulatory Authorities and the expiration
of all mandatory waiting periods, and assuming due authorization, execution and
delivery of this Agreement and the Plan of Merger by each of Parent and Merger
Subsidiary, this Agreement and the Plan of Merger each represents a legal,
valid, and binding obligation of Subject Company, enforceable against Subject
Company in accordance with its terms (except in all cases as such enforceability
may be limited by applicable bankruptcy, insolvency, reorganization,
receivership, conservatorship, moratorium, or similar Laws (including provisions
of the U.S., Louisiana and Tennessee Constitutions) affecting the enforcement of
creditors' rights generally and except that the availability of equitable
remedies is subject to the discretion of the court before which any proceeding
may be brought).

                  (b) Neither the execution and delivery of this Agreement or
the Plan of Merger by Subject Company, nor the consummation by Subject Company,
of the transactions contemplated hereby, nor compliance by Subject Company with
any of the provisions hereof or thereof, will (i) conflict with or result in a
breach of any provision of the Articles of Incorporation or Bylaws of Subject
Company, or (ii) constitute or result in a Default under, or require any Consent
(excluding Consents required by Law or Order) pursuant to, or result in the
creation of any Lien on any material Asset of Subject Company or any Subject
Company Subsidiary under, any Contract or Permit of Subject Company or any
Subject Company Subsidiary, except for such Defaults and Liens which are not,
and for such Consents which, if not obtained, are not, reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on Subject
Company, or (iii) subject to receipt of the requisite Consents referred to in
Section 9.1(b) of this Agreement, violate any Law or Order applicable to Subject
Company, its Subsidiaries or any of their respective material Assets.

                  (c) Other than in connection or compliance with the provisions
of the Securities Laws, applicable state corporate and securities Laws, and
other than Consents required from the FRB and from the LOFI, and other than
Consents, filings, or notifications which, if not obtained or made, are not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Subject Company, no notice to, filing with, or Consent of, any public
body or authority is necessary for the consummation by Subject Company of the
Merger and the other transactions contemplated in this Agreement.

         5.3 Capital Stock. (a) The authorized capital stock of Subject Company
consists solely of: (i) 1,000,000 shares of Subject Company Common Stock, of
which not more than 145,732 shares of Subject Company Common Stock are
outstanding as of the date of this Agreement (exclusive of treasury shares) and
not more than 145,732 shares of Subject Company Common Stock will be issued and
outstanding at the Effective Time, and (ii) 1,000,000 shares of Subject Company
Preferred Stock, of which no shares are outstanding as of the date of this
Agreement and no shares of Subject Company Preferred Stock will be issued and
outstanding at the Effective Time.

<PAGE>   116




All of the issued and outstanding shares of Subject Company Common Stock are
duly and validly issued and outstanding and are fully paid and nonassessable
under the LBCL and Subject Company's Articles of Incorporation and Bylaws. None
of the outstanding shares of Subject Company Common Stock has been issued in
violation of any preemptive rights of the current or past shareholders of
Subject Company.

                  (b) Other than as set forth in Section 5.3(a) of this
Agreement, there are no shares of capital stock or other equity securities of
Subject Company outstanding and no outstanding Rights relating to the capital
stock of Subject Company.

         5.4 Subject Company Subsidiaries. Subject Company has disclosed in
Section 5.4 of the Subject Company Disclosure Memorandum all of the Subject
Company Subsidiaries that are corporations (identifying its jurisdiction of
incorporation) and all of the Subject Company Subsidiaries that are general or
limited partnerships or other non-corporate entities (identifying the Law under
which such entity is organized, and the amount and nature of the ownership
interest therein of Subject Company Subsidiaries). Except as set forth in
Section 5.4 of the Subject Company Disclosure Memorandum, Subject Company or one
of its wholly-owned Subsidiaries owns all of the issued and outstanding shares
of capital stock (or other equity interests) of each of the Subject Company
Subsidiaries. Except as set forth in Section 5.4 of the Subject Company
Disclosure Memorandum, no capital stock (or other equity interest) of any
Subject Company Subsidiary is or may become required to be issued (other than to
another Subject Company Subsidiary) by reason of any Rights, and there are no
Contracts by which Subject Company or any of the Subject Company Subsidiaries is
bound to issue (other than to Subject Company or another of the Subject Company
Subsidiaries) additional shares of its capital stock (or other equity interests)
or Rights or by which Subject Company or any of the Subject Company Subsidiaries
is or may be bound to transfer any shares of the capital stock (or other equity
interests) of any of Subject Company or any of the Subject Company Subsidiaries
(other than to Subject Company or any of the Subject Company Subsidiaries).
Except as set forth in Section 5.4 of the Subject Company Disclosure Memorandum,
there are no Contracts relating to the rights of Subject Company or any Subject
Company Subsidiary to vote or to dispose of any shares of the capital stock (or
other equity interests) of Subject Company or any Subject Company Subsidiary.
All of the shares of capital stock (or other equity interests) of each Subject
Company Subsidiary held by Subject Company or any Subject Company Subsidiary are
fully paid and are owned by Subject Company or a Subject Company Subsidiary free
and clear of any Liens. Each Subject Company Subsidiary is either a bank or a
corporation, and each such Subsidiary is duly organized, validly existing, and
(as to corporations) in good standing under the Laws of the jurisdiction in
which it is incorporated or organized, and has the corporate power and authority
necessary for it to own, lease, and operate its Assets and to carry on its
business as now conducted. Each Subject Company Subsidiary is duly qualified or
licensed to transact business as a foreign corporation in good standing in each
of the States of the United States and in each foreign jurisdiction where the
character of its Assets or the nature or conduct of its business requires it to
be so qualified or licensed, except for such jurisdictions in which the failure
to be so qualified or licensed is not reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect on Subject Company. The only Subject
Company Subsidiary that is a depository institution is Bank of LaPlace of St.
John the Baptist Parish, Louisiana (the "Bank"). The Bank is an "insured
depository institution" as defined in Section 3(c)(2) of the Federal Deposit
Insurance Act and applicable regulations thereunder. The deposits in the Bank
are insured by the Federal Deposit Insurance Corporation to the maximum extent
permitted by the Federal Deposit Insurance Act, as amended, and applicable
regulations thereunder. The Bank is a member of the Bank Insurance Fund. The
minute book and other organizational documents (and all amendments thereto) for
Subject Company and each Subject Company Subsidiary that is a "Significant
Subsidiary" (as such term is defined in Rule 1.02(w) of Regulation S-X
promulgated under the Securities Laws) have been or will be made available to
Parent for its review, and are true and complete (except as set forth in Section
5.4 of the Subject Company Disclosure Memorandum) in all material respects as in
effect as of the date of this Agreement.

Subject Company nor any of the Subject Company Subsidiaries has been a member of
an affiliated group filing a consolidated federal income tax return (other than
a group the common parent of which was Subject Company) or has any Liability for
taxes of any Person (other than Subject Company and the Subject Company
Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar
provision of state, local, or foreign Law) as a transferee or successor or by
Contract or otherwise.

         5.9 Assets. Except as disclosed or reserved against in the Subject
Company Financial Statements made available prior to the date of this Agreement,
Subject Company and the Subject Company Subsidiaries have good and indefeasible
title, free and clear of all Liens, to all of their respective material Assets
reflected on the balance sheet as of March 31, 1998 included in such Subject
Company Financial Statements, other than any of such Assets which have been sold

business of Subject Company and its Subsidiaries, except for instances in which
the failure to so be is not reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Subject Company. All Assets which are
material to Subject Company's business on a consolidated basis, held under
leases or subleases by the Subject Company or any of the Subject Company
Subsidiaries, are held under valid Contracts enforceable in accordance with
their respective terms (except as enforceability may be limited by applicable

all Intellectual Property material to the business of Subject Company. To the
Knowledge of Subject Company, none of the Intellectual Property material to the
business conducted by Subject Company or the Subject Company Subsidiaries
infringes upon or otherwise violates the rights of any Person, nor has any

Company nor the Subject Company Subsidiaries is obligated to pay any royalties
to any Person with respect to any such Intellectual Property. To the Knowledge

Person, including Subject Company or any of the Subject Company Subsidiaries.

Effect on Subject Company.

                  (b) To the Knowledge of Subject Company, there is no

affecting a site owned, leased, or operated by Subject Company or any of the
Subject Company Subsidiaries or any of their respective Operating Properties or
Participation Facilities, except for such Litigation pending or threatened that
is not reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on Subject Company, nor, to the Knowledge of Subject Company, is
there any reasonable basis for any Litigation of a type described in this

         5.12 Compliance With Laws. Subject Company is duly registered as a bank
holding company under the BHC Act. Each of Subject Company and the Subject
Company Subsidiaries has in effect all Permits necessary for it to own, lease,
or operate its material Assets and to carry on its business as now conducted,
except where the failure to hold such Permits would not be reasonably likely to
have, individually or in the aggregate, a Material Adverse Effect on Subject

Company), (ii) threatening to revoke any material Permits, or (iii) requiring
Subject Company or any of the Subject Company Subsidiaries to enter into or
consent to the issuance of a cease and desist order, formal agreement,

Company Subsidiaries is the subject of any Litigation asserting that Subject
Company or any of the Subject Company Subsidiaries has committed an unfair labor
practice (within the meaning of the National Labor Relations Act or comparable
state Law) or seeking to compel Subject Company or any of the Subject Company
Subsidiaries to bargain with any labor organization as to wages or conditions of
employment, nor is there any strike or other labor dispute (excluding matters
which are not reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on Subject Company) involving Subject Company or any of
the Subject Company Subsidiaries, pending or, to the Knowledge of Subject
Company, threatened, nor to the Knowledge of Subject Company, is there any
activity involving Subject Company's or any of the Subject Company Subsidiaries'
employees seeking to certify a collective bargaining unit or engaging in any
other collective bargaining organizational activity.

employee stock ownership, severance pay, vacation, bonus, or other material
incentive plans, all other written employee programs, arrangements, or
agreements, all medical, vision, dental, or other health plans, all life

Company or any Subject Company Subsidiary and under which employees, retirees,
dependents, spouses, directors, independent contractors, or other beneficiaries
of Subject Company or any Subject Company Subsidiary are eligible to participate
(collectively, the "Subject Company Benefit Plans"). Any of the Subject Company
Benefit Plans which is an "employee pension benefit plan," as that term is

ERISA Plan." Neither Subject Company nor any Subject Company Subsidiary
maintains any "defined benefit plan" (as defined in Section 414(j) of the

multiemployer plan within the meaning of Section 3(37) of ERISA.

401(a) of the Internal Revenue Code either is a standardized prototype plan or
has received a favorable determination letter from the Internal Revenue Service,
and Subject Company is not aware of any circumstances likely to result in
revocation of any such favorable determination letter. To the Knowledge of
Subject Company, neither Subject Company nor any of the Subject Company
Subsidiaries is subject to a Tax imposed by Section 4975 of the Internal Revenue
Code or a civil penalty imposed by Section 502(i) of ERISA.

                  (c) No "defined benefit plan" (as defined in Section 414(j) of
the Internal Revenue Code) or any "single-employer plan," within the meaning of
Section 4001(a)(15) of ERISA, formerly maintained by Subject Company or any of
the Subject Company Subsidiaries, or the single-employer plan of any entity
which is considered one employer with Subject Company under Section 4001 of
ERISA or Section 414 of the Internal Revenue Code or Section 302 of ERISA
(whether or not waived) (an "ERISA Affiliate") has an "accumulated funding
deficiency" within the meaning of Section 412 of the Internal Revenue Code or
Section 302 of ERISA. Neither Subject Company nor any of the Subject Company
Subsidiaries has provided, or, to Subject Company's knowledge, is required to

no material Liability under Subtitle C or D of Title IV of ERISA has been
incurred by Subject Company or any of the Subject Company Subsidiaries with
respect to any current, frozen, or terminated single-employer plan or the
single-employer plan of any ERISA Affiliate. Neither Subject Company nor any of
the Subject Company Subsidiaries has incurred any withdrawal Liability with
respect to a multiemployer plan under Subtitle E of Title IV of ERISA
(regardless of whether based on contributions of an ERISA Affiliate). No notice
of a "reportable event," within the meaning of Section 4043 of ERISA for which
the 30 day reporting requirement has not been waived, has been required to be
filed for any Subject Company Pension Plan or by any ERISA Affiliate within the
12 month period ending on the date hereof.

                  (e) Neither Subject Company nor any of the Subject Company
Subsidiaries has any material Liability for retiree health and life benefits
under any of the Subject Company Benefit Plans, and there are no restrictions on
the rights of Subject Company or any of the Subject Company Subsidiaries to
amend or terminate any such retiree health or benefit Plan without incurring
Liability thereunder.

                  (f) Except as set forth in Section 5.14(f) of the Subject
Company Disclosure Memorandum, neither the execution and delivery of this
Agreement nor the consummation of the transactions contemplated hereby will (i)
result in any payment (including severance, unemployment compensation or golden
parachute) becoming due to any director or any employee of Subject Company or
any of the Subject Company Subsidiaries from Subject Company or any of the
Subject Company Subsidiaries under any Subject Company Benefit Plan, (ii)
increase any benefits otherwise payable under any Subject Company Benefit Plan,
or (iii) result in any acceleration of the time of payment or vesting of any
such benefit.

                  (g) The actuarial present values of all accrued deferred
compensation entitlements (including entitlements under any executive
compensation, supplemental retirement, or employment agreement) of employees and
former employees of any Subject Company Subsidiary and their respective
beneficiaries, other than entitlements accrued pursuant to funded retirement
plans subject to the provisions of Section 412 of the Internal Revenue Code or
Section 302 of ERISA, have been fully reflected on the Audited Subject Company
Financial Statements to the extent required by and in accordance with GAAP.

         5.15 Material Contracts. Except as set forth in Section 5.15 of the
Subject Company Disclosure Memorandum, neither Subject Company, the Subject
Company Subsidiaries, nor any of their respective Assets, businesses or
operations, is a party to, or is bound or affected by, or receives benefits
under, (i) any employment, severance, termination, consulting, or retirement
Contract, (ii) any Contract relating to the borrowing of money by Subject
Company or any of the Subject Company Subsidiaries or the guarantee by Subject

of federal funds, Federal Home Loan Bank advances, fully-secured repurchase
agreements, trade payables, and Contracts relating to borrowings or guarantees
made in the ordinary course of business), (iii) any Contracts which prohibit or
restrict Subject Company or any of the Subject Company Subsidiaries from
engaging in any business activities in any geographic area, line of business, or
otherwise in competition with any other Person, (iv) any Contracts between or
among Subject Company and the Subject Company Subsidiaries, (v) any
exchange-traded or over-the-counter swap, forward, future, option, cap, floor,
or collar financial Contract, or any other interest rate or foreign currency
protection Contract (not disclosed in the Subject Company Financial Statements
delivered prior to the date of this Agreement) which is a financial derivative
Contract (including various combinations thereof), and (vi) any other Contract
or amendment thereto that would be required to be filed as an exhibit to a
Subject Company SEC Document which would have been filed by Subject Company
prior to the date of this Agreement if Subject Company was required to file SEC

of this Agreement, the "Subject Company Contracts"). With respect to each

thereunder, other than Defaults which are not reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on Subject Company);

or waived any material provision of any such Contract; and (iv) no other party
to any such Contract is, to the Knowledge of Subject Company, in Default in any

Except as set forth in Section 5.15 of the Subject Company Disclosure
Memorandum, all of the indebtedness of Subject Company or any Subject Company
Subsidiary for money borrowed is prepayable at any time by Subject Company or
the particular Subject Company Subsidiary without material penalty or premium.

         5.16 Legal Proceedings. There is no Litigation instituted or pending,
or, to the Knowledge of Subject Company, threatened (or unasserted but
considered probable of assertion and which if asserted would have at least a
reasonable probability of an unfavorable outcome) against Subject Company or any
of the Subject Company Subsidiaries, or against any Asset, employee benefit
plan, interest, or right of any of them, that is reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on Subject Company,
nor are there any Orders of any Regulatory Authorities, other governmental
authorities, or arbitrators outstanding against Subject Company or any of the
Subject Company Subsidiaries. Section 5.16 of the Subject Company Disclosure
Memorandum includes a summary report of all material Litigation as of the date
of this Agreement which names Subject Company or a Subject Company Subsidiary as
a defendant or cross-defendant.

         5.17 Reports. Since January 1, 1995, or the applicable date of

timely filed all reports and statements, together with any amendments required
to be made with respect thereto, that it was required to file with (i) the SEC,
if any, (ii) other Regulatory Authorities, and (iii) any applicable state
securities or banking authorities, except untimely filings or failures to file
which are not reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on Subject Company. As of its respective date (or, if
amended or superseded by a filing prior to the date of this Agreement, then on
the date of such filing), each of such reports and documents, including the
financial statements, exhibits, and schedules thereto, complied in all material
respects with all applicable Laws. As of its respective date (or, if amended or
superseded by a filing prior to the date of this Agreement, then on the date of
such filing), no Subject Company document or report contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances under which they were made, not misleading. None of the Subject
Company Subsidiaries is required to file any SEC Documents.

         5.18 Statements True and Correct. None of the information supplied or
to be supplied by Subject Company expressly for inclusion in the Registration
Statement to be filed by Parent with the SEC will, when the Registration
Statement becomes effective, be false or misleading with respect to any material
fact, or omit to state any material fact necessary to make the statements
therein not misleading. None of the information supplied or to be supplied by
Subject Company expressly for inclusion in the Subject Company Proxy Statement
to be mailed to Subject Company's shareholders in connection with the Subject

are filed, and with respect to the Subject Company Proxy Statement, when first
mailed to the shareholders of Subject Company, be false or misleading with
respect to any material fact, or omit to state any material fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, or, in the case of the Subject Company Proxy Statement or
any amendment thereof or supplement thereto, at the time of the Subject Company
Shareholders' Meeting, be false or misleading with respect to any material fact,
or omit to state any material fact necessary to correct any statement made by
Subject Company in any earlier communication with respect to the solicitation of
any proxy for the Subject Company Shareholders' Meeting. All documents that
Subject Company or any Subject Company Subsidiary is responsible for filing with
any Regulatory Authority in connection with the transactions contemplated hereby
will comply as to form in all material respects with the provisions of
applicable Law.

         5.19 Accounting, Tax, and Regulatory Matters. Neither Subject Company
nor any of the Subject Company Subsidiaries has taken any action or has any
Knowledge of any fact or circumstance relating to Subject Company that is
reasonably likely to (i) prevent the transactions contemplated hereby, including
the Merger, from qualifying for pooling-of-interests accounting treatment or as
a reorganization within the meaning of Section 368(a) of the Internal Revenue
Code, or (ii) materially impede or delay receipt of any Consents of Regulatory
Authorities referred to in Section 9.1(b) of this Agreement.

         5.20 Charter Provisions; Takeover Laws. Subject Company has taken all
action so that the entering into of this Agreement and the consummation of the
Merger and the other transactions contemplated by this Agreement do not and will
not result in the grant of any rights to any Person under the Articles of
Incorporation, Bylaws or other governing instruments of Subject Company or any
Subject Company Subsidiary or restrict or impair the ability of Parent or any of
the Parent Subsidiaries to vote, or otherwise to exercise the rights of a
shareholder with respect to, shares of Subject Company or any Subject Company
Subsidiary. Subject Company has taken all necessary action to exempt this
Agreement and the Plan of Merger from, and the transactions contemplated hereby
and thereby are exempt from, any "super-majority" voting requirements or the
requirements of any "moratorium," "fair price," "business combination," "control
share," or other anti-takeover provisions under applicable Laws, or the Articles
of Incorporation or Bylaws of the Subject Company or any Subject Company
Subsidiary (collectively, "Takeover Laws").

Subsidiary, or (iii) subject to receipt of the requisite Consents referred to in
Section 9.1(b) of this Agreement, violate any Law or Order applicable to Parent
or any Parent Subsidiary or any of their respective material Assets.

nonassessable (except pursuant to 12 U.S.C. Section 55 in the case of national
banks and comparable, applicable state Law, if any, in the case of state
depository institutions) under the applicable corporation or similar Law of the
jurisdiction in which such Subsidiary is incorporated or organized and are owned
by Parent or a Parent Subsidiary free and clear of any Liens. None of the issued
and outstanding shares of capital stock of Merger Subsidiary, and none of the
issued and outstanding stock of any other Parent Subsidiary which qualifies as a
Significant Subsidiary of Parent, has been issued in violation of any preemptive
rights of any Person. Each Parent Subsidiary is either a bank, federal savings
bank, or a savings association, partnership, limited liability company or a
corporation, and each such Parent Subsidiary which qualifies as a Significant
Subsidiary of Parent is duly organized, validly existing and (as to
corporations) in good standing under the Laws of the jurisdiction in which it is
incorporated or organized, and has the corporate power and authority necessary
for it to own, lease, and operate its Assets and to carry on its business as now
conducted. Each Parent Subsidiary which qualifies as a Significant Subsidiary of
Parent is duly qualified or licensed to transact business as a foreign
corporation in good standing in each of the States of the United States and in
each foreign jurisdiction where the character of its Assets or the nature or
conduct of its business requires it to be so qualified or licensed, except for
such jurisdictions in which the failure to be so qualified or licensed is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Parent.

         6.5 Financial Statements. Each of the Parent Financial Statements
(including, in each case, any related notes) contained in the Parent SEC
Documents, including any Parent SEC Document filed after the date of this
Agreement until the Effective Time,: (i) complied, or will comply, as to form in
all material respects with the applicable published rules and regulations of the
SEC with respect thereto, (ii) was prepared, or will be prepared, in accordance
with GAAP applied on a consistent basis throughout the periods involved (except
as may be indicated in the notes to such financial statements or, in the case of
unaudited interim statements, as permitted by Regulation S-X promulgated under
the Securities Laws), (iii) fairly presented, or will fairly present, in all
material respects the consolidated financial position of Parent and the Parent
Subsidiaries as at the respective dates and the consolidated results of its
operations and cash flows for the periods indicated, except that the unaudited
interim financial statements were or are subject to normal and recurring
year-end adjustments which were not or are not expected to be material in amount
or effect.

         6.6 Absence of Undisclosed Liabilities. Neither Parent nor any of the
Parent Subsidiaries has any Liabilities that are reasonably likely to have,
individually or in the aggregate, a Material Adverse Effect on Parent, except
Liabilities which are accrued or reserved against in the consolidated balance
sheets of Parent as of December 31, 1997, or which are included in the Parent
Financial Statements made available prior to the date of this Agreement, or
reflected in the notes and schedules, if any, thereto. Neither Parent nor any of
the Parent Subsidiaries has incurred or paid any Liability since March 31, 1998,
except for such Liabilities incurred or paid (i) which are not reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect on Parent
or (ii) in connection with the transactions contemplated by this Agreement.

         6.7 Absence of Certain Changes or Events. Since March 31, 1998, except
as disclosed in the Parent SEC Documents made available prior to the date of
this Agreement, there have been no events, changes, or occurrences which have
had, or are reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on Parent.

         6.8 Compliance With Laws. Parent is duly registered as a bank holding
company under the BHC Act. Each of Parent and the Parent Subsidiaries has in
effect all Permits necessary for it to own, lease, or operate its material
Assets and to carry on its business as now conducted, except where the failure
to hold such permits would not be reasonably likely to have, individually or in
the aggregate, a Material Adverse Effect on Parent. Neither Parent nor any of
the Parent Subsidiaries:

                  (a) is in violation of any Laws, Orders, or Permits applicable
to its business or employees conducting its business, except for such violations
which would not be reasonably likely to have, individually or in the aggregate,
a Material Adverse Effect on Parent; or

                  (b) has received any notification or communication since
January 1, 1996 from any agency or department of federal, state, or local
government or any Regulatory Authority or the staff thereof (i) asserting that
Parent or any Parent Subsidiary is in violation of any of the Laws or Orders
which such governmental authority or Regulatory Authority enforces (excluding
violations which would not be reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Parent), (ii) threatening to revoke any
material Permits, or (iii) requiring Parent or any Parent Subsidiary to enter
into or consent to the issuance of a cease and desist order, formal agreement,
directive, commitment or memorandum of understanding, or to adopt any Board
resolution or similar undertaking, which is still in effect and which restricts
materially the conduct of its business, or in any manner relates to its capital
adequacy, its credit or reserve policies, its management, or the payment of
dividends.

         6.9 Legal Proceedings. There is no Litigation instituted or pending,
or, to the Knowledge of Parent, threatened (or unasserted but considered
probable of assertion and which if asserted would have at least a reasonable
probability of an unfavorable outcome) against Parent or any Parent Subsidiary,
or against any Asset, employee benefit plan, interest, or right of any of them,
that is reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect on Parent, nor are there any Orders of any Regulatory
Authorities, other governmental authorities, or arbitrators outstanding against
Parent or any Parent Subsidiary.

         6.10 Reports. Since January 1, 1995, or the applicable date of
organization if later, Parent and each Parent Subsidiary has timely filed all
reports and statements, together with any amendments required to be made with
respect thereto, that it was required to file with (i) the SEC, including, but
not limited to, Forms 10-K, Forms 10-Q, Forms 8-K, and proxy statements, (ii)
other Regulatory Authorities, and (iii) any applicable state securities or
banking authorities, except untimely filings or failures to file which are not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Parent. As of its respective date (or, if amended or superseded by a
filing prior to the date of this Agreement, then on the date of such filing),
each of such reports and documents, including the financial statements,
exhibits, and schedules thereto, complied in all material respects with all
applicable Laws. As of its respective date, no Parent document or report
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements made
therein, in light of the circumstances under which they were made, not
misleading. Except for Parent Subsidiaries that are registered as a broker,
dealer, or investment advisor, no Parent Subsidiary is required to file any SEC
Documents.

         6.11 Statements True and Correct. None of the information supplied or
to be supplied by Parent or any Parent Subsidiary expressly for inclusion in the
Registration Statement to be filed by Parent with the SEC, will, when the
Registration Statement becomes effective, be false or misleading with respect to
any material fact, or omit to state any material fact necessary to make the
statements therein not misleading. None of the information supplied or to be
supplied by Parent or any Parent Subsidiary expressly for inclusion in the
Subject Company Proxy Statement to be mailed to Subject Company's shareholders
in connection with the Subject Company Shareholders' Meeting, and any other
documents to be filed by Parent or any Parent Subsidiary with the SEC or any
other Regulatory Authority in connection with the transactions contemplated
hereby, will, at the respective time such documents are filed, and with respect
to the Subject Company Proxy Statement, when first mailed to the shareholders of
Subject Company, be false or misleading with respect to any material fact, or
omit to state any material fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading, or, in
the case of the 


                  LaPlace Bancshares - Merger Agreement Page 16


<PAGE>   127



Subject Company Proxy Statement or any amendment thereof or supplement thereto,
at the time of the Subject Company Shareholders' Meeting, be false or misleading
with respect to any material fact, or omit to state any material fact necessary
to correct any information supplied or to be supplied by Parent or any Parent
Subsidiary which was contained in any earlier communication with respect to the
solicitation of any proxy for the Subject Company Shareholders' Meeting. All
documents that Parent or any Parent Subsidiary is responsible for filing with
any Regulatory Authority in connection with the transactions contemplated hereby
will comply as to form in all material respects with the provisions of
applicable Law.

         6.12 Accounting, Tax, and Regulatory Matters. Neither Parent nor any
Parent Subsidiary has taken any action or has any Knowledge of any fact or
circumstance relating to Parent that is reasonably likely to (i) prevent the
transactions contemplated hereby, including the Merger, from qualifying for
treatment as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code, or (ii) materially impede or delay receipt of any
Consents of Regulatory Authorities referred to in Section 9.1(b) of this
Agreement, or (iii) prevent the transactions contemplated hereby, including the
Merger, from qualifying for pooling-of-interests accounting treatment.

of their respective Assets, businesses or operations is a party to, or is bound
or affected by, or receives benefits under, any Contract or amendment thereto

by Parent prior to the date of this Agreement. With respect to each Parent
Material Contract: (i) the Contract is in full force and effect; (ii) neither
Parent nor any Parent Subsidiary is in Default thereunder, other than Defaults
which are not reasonably likely to have, individually or in the aggregate, a
Material Adverse Effect on Parent; (iii) neither Parent nor any Parent
Subsidiary has repudiated or waived any material provision of any such Contract;
and (iv) no other party to any such Contract is, to the Knowledge of Parent, in
Default in any material respect or has repudiated or waived any material

entering into this Agreement, Subject Company covenants, acknowledges, and
agrees that it shall be a specific, absolute, and unconditionally binding
condition precedent to Subject Company's entering into a letter of intent,
agreement in principle, or definitive agreement (whether or not considered
binding, non-binding, conditional or unconditional) with any third party with
respect to an Acquisition Proposal, or supporting or indicating an intent to
support an Acquisition Proposal, other than this Agreement and the transactions
contemplated in this Agreement, regardless of whether Subject Company has
otherwise complied with the provisions of Section 8.8(a) hereof, that Subject
Company or such third party which is a party of the Acquisition Proposal shall
have paid Parent, as liquidated damages, the sum of Eight Hundred Thousand
Dollars ($800,000), which sum represents the (i) direct costs and expenses
(including, but not limited to, fees and expenses incurred by Parent's financial
or other consultants, printing costs, investment bankers, accountants, and
counsel) incurred by or on behalf of Parent in negotiating and undertaking to
carry out the transactions contemplated by this Agreement; and (ii) indirect
costs and expenses of Parent in connection with the transactions contemplated by
this Agreement, including Parent's management time devoted to negotiation and
preparation for the transactions contemplated by this Agreement; and (iii)
Parent's loss as a result of the transactions contemplated by this Agreement not

that prior to Subject Company's entering into a letter of intent, agreement in
principle, or definitive agreement, (whether binding or non-binding, conditional
or unconditional) with any third party with respect to an Acquisition Proposal
or supporting or indicating an intent to support an Acquisition Proposal, either
Subject Company or such third party shall have paid to Parent the amount set
forth above in immediately available funds to satisfy the specific, absolute,
and unconditionally binding condition precedent imposed by this Section 8.8.
Notwithstanding anything to the contrary in this Section 8.8(b), in the event
such Acquisition Proposal should be the result of a hostile takeover of Subject
Company, any sums due Parent hereunder shall be paid only at the closing of the
transactions set forth in such Acquisition Proposal. Parent acknowledges that
under no circumstances shall any officer or director of Subject Company) (unless
such officer or director shall have an interest in a potential acquiring party
in any Acquisition Proposal) be held personally liable to Parent for any amount
of the foregoing payment. On payment of such amount to Parent, Parent shall have
no cause of action or claim (either in law or equity) whatsoever against Subject
Company, or any officer of director of Subject Company, with respect to or in
connection with such Acquisition Proposal or this Agreement.

                  (c) The requirements, conditions, and obligations imposed by
Section 8.8(b) shall continue in full force and effect from the date of this
Agreement until the earlier of (i) the Effective Time; (ii) September 30, 1999;
or (iii) the date on which this Agreement shall have been terminated (A)
mutually by the Parties pursuant to Section 10.1(a) of this Agreement; (B) by

Subject Company pursuant to Section 10.1(e) or Section 10.1(f), unless the
failure to consummate the transactions contemplated by this Agreement by March
31, 1999, results from or is related to pending or threatened Litigation arising
out of or in connection with the Merger or an Acquisition Proposal related to
Subject Company or any Subject Company Subsidiary, in which case the date shall
be extended to that date which is thirty (30) days after the final termination
of such Litigation or threatened Litigation; (D) by either Party pursuant to

         8.9 Accounting and Tax Treatment. Each of the Parties undertakes and
agrees to use its reasonable efforts to cause the Merger, and to take no action
which would cause the Merger not, to qualify for pooling-of-interests accounting
treatment and treatment as a "reorganization" within the meaning of Section
368(a) of the Internal Revenue Code for federal income tax purposes.

         8.10 Agreement of Affiliates. Subject Company has disclosed in Section
8.10 of the Subject Company Disclosure Memorandum each Person whom it reasonably
believes may be deemed to be an "affiliate" of Subject Company as of the date of
this Agreement for purposes of Rule 145 under the 1933 Act. Subject Company
shall use its reasonable efforts to cause each such Person to deliver to Parent,
not later than 40 days prior to the Effective Time, a written agreement,
substantially in the form of Exhibit 2, providing that such Person: (i) will not
sell, transfer, or otherwise dispose of the shares of Subject Company Common
Stock held by such Person, except as contemplated by such agreement or by this
Agreement, and (ii) will not sell, transfer, or otherwise dispose of the shares
of Parent Common Stock to be received by such Person upon consummation of the
Merger except in compliance with applicable provisions of the 1933 Act and the
rules and regulations thereunder and until such time as financial results
covering at least 30 days of combined operations of Parent and Subject Company
have been published within the meaning of Section 201.01 of the SEC's
Codification of Financial Reporting Policies. If the Merger will qualify for
pooling-of-interests accounting treatment, shares of Parent Common Stock issued
to such affiliates of Subject Company in exchange for shares of Subject Company
Common Stock shall not be transferable until such time as financial results
covering at least 30 days of combined operations of Parent and Subject Company
have been published within the meaning of Section 201.01 of the SEC's
Codification of Financial Reporting Policies, regardless of whether each such
affiliate has provided the written agreement referred to in this Section 8.10
(and Parent shall be entitled to place restrictive legends upon certificates for
shares of Parent Common Stock issued to affiliates of Subject Company pursuant
to this Agreement to enforce the provisions of this Section 8.10). Parent shall
not be required to maintain the effectiveness of the Registration Statement
under the 1933 Act for the purposes of resale of Parent Common Stock by such
affiliates.

         8.11 Employee Benefits and Contracts. Following the Effective Time,
Parent shall provide to officers and employees of the Subject Company and any
Subject Company Subsidiary, employee benefits under employee benefit and welfare
plans of Parent or the Parent Subsidiaries on terms and conditions which when
taken as a whole are substantially similar to those currently provided by Parent
or a Parent Subsidiary to their similarly situated officers and employees. For
purposes of participation, vesting, and benefit accrual under such employee
benefit plans, the service of the employees of the Subject Company and any
Subject Company Subsidiary prior to the Effective Time shall be treated as
service with Parent or a Parent Subsidiary participating in such employee
benefit plans. At and after the Effective Time, all contributions under Subject
Company's 401(k) Plan ("Plan") as in effect on the date of the Agreement shall
cease and employees of Subject Company and the Subject Company Subsidiaries who
continue their employment with Parent or Parent's Subsidiaries after the
Effective Time shall be entitled to participate in Parent's 401(k) Plan to the
same extent as other employees of Parent as of immediately after the Effective
Time. Subject Company, in coordination with Parent's Human Resources Department,
shall take such steps as are necessary to merge Subject Company's 401(k) Plan
with and into Parent's 401(k) Plan as of the Effective Time or as soon as
reasonably practicable after the Effective Time, but any delay in effectuating
such merger shall not delay Subject Company's employees' right to participate in
Parent's 401(k) Plan as of the Effective Time; provided, however, that should a
merger of Subject Company's Plan be prohibited by law or not administratively
feasible, as determined by Parent's Human Resources Department and communicated
to Subject Company at least 60 days prior to the Effective Time of the Merger,
then Subject Company shall take such steps necessary to terminate its 401(k)
Plan as of or immediately prior to the Effective Time of the Merger. Prior to
the Effective Time, Subject Company shall fully reserve for all anticipated
costs and expenses related to its 401(k) Plan and the merger thereof into
Parent's 401(k) Plan, or termination thereof, whichever may be the case. Subject
Company, in coordination with Parent's Human Resources Department, shall obtain
such regulatory determinations regarding the termination of Subject Company's
401(k) Plan, if applicable, or regarding the merger of Subject Company's Plan
into the Parent 401(k) Plan, in either case as may be appropriate to ensure the
qualified status of such plans and related trusts under the Code. Additionally,
after the Effective Time, the continuing employees of Subject Company and any
Subject Company Subsidiary shall be immediately eligible to receive group
hospitalization, medical, life, disability, and other


                  LaPlace Bancshares - Merger Agreement Page 23


<PAGE>   134



employee welfare benefits no less than those provided to other employees of
Parent or Parent Subsidiaries holding comparable positions. Notwithstanding
anything to the contrary above, beginning with the first calendar day of the
first calendar year following the Effective Time, Subject Company employees
shall become subject to Parent's policies and procedures relative to accrued
vacation, sick leave and other paid time-off benefits. For the remainder of the
calendar year in which the Effective Time of the Merger occurs, however, all
existing Subject Company vacation, sick leave and other paid time-off benefits
will remain in force and effect as to the then former Subject Company employees
and shall be administered in accordance with the terms of such plans and
consistent with past practices. On January 1st next following the Effective Time
of the Merger, the Subject Company vacation, sick leave and other paid time-off
benefit plans and arrangements shall terminate. In their place Parent's
vacation, sick leave and other paid time-off benefit plans, arrangements and
policies shall become effective and applicable to the then former Subject
Company employees who are still employed by Parent or any of its Subsidiaries.
The applicable then former Subject Company employees shall not be allowed to
carryover or carry forward any accrued vacation, sick leave or other paid
time-off benefits under the former Subject Company plans and neither Subject
Company, any Subject Company Subsidiary, Parent nor any Parent Subsidiary shall
pay for any of the accrued vacation, sick leave other paid time-off days or
benefits under the Subject Company plans unless payment for lost accrued days or
benefits is specifically provided for in the respective plans as they exist on
the date hereof. The agreement of Parent to provide Subject Company employees
with credit for prior service is based on the representation by Subject Company
that its vacation, sick leave and other paid time-off benefit plans do not
provide for payment of unused days or benefits upon termination of the plans or
should the employee's employment with Subject Company or any Subject Company
Subsidiary be terminated for any reason.

         8.12 Indemnification. (a) After the Effective Time, Parent shall
indemnify, defend and hold harmless the present and former directors, officers,
employees, and agents of the Subject Company and any Subject Company Subsidiary
(each, an "Indemnified Party") (including any person who becomes a director,
officer, employee, or agent prior to the Effective Time) against all Liabilities
(including reasonable attorneys' fees, and expenses, judgments, fines and
amounts paid in settlement) arising out of actions or omissions occurring (or
alleged to have occurred) at or prior to the Effective Time to the full extent
permitted under any of Tennessee Law, Louisiana Law, Subject Company's Articles
of Incorporation and Bylaws as in effect on the date hereof, and any indemnity
agreements entered into prior to the date hereof between Subject Company or a
Subject Company Subsidiary and any Indemnified Party, whichever is greater.
Without limiting the foregoing, in any case in which approval by Parent is
required to effectuate any indemnification, Parent shall direct, at the election
of the Indemnified Party, that the determination of any such approval shall be
made by independent counsel mutually agreed upon between Parent and the
Indemnified Party.

                  (b) Any Indemnified Party wishing to claim indemnification
under paragraph (a) of this Section 8.12, upon learning of any such Liability or
Litigation, shall promptly notify Parent thereof, provided that the failure so
to notify shall not affect the obligations of Parent under this Section 8.12
unless and to the extent such failure materially increases Parent's Liability
under this Section 8.12. In the event of any such Litigation (whether arising
before or after the Effective Time), (i) Parent or the Surviving Corporation
shall have the right to assume the defense thereof and Parent shall not be
liable to such Indemnified Parties for any legal expenses of other counsel or
any other expenses subsequently incurred by such Indemnified Parties in
connection with the defense thereof, except that if Parent or the Surviving
Corporation elects not to assume such defense or counsel for the Indemnified
Parties advises that there are substantive issues which raise conflicts of
interest between Parent or the Surviving Corporation and the Indemnified Parties
or between the Indemnified Parties, the Indemnified Parties may retain counsel
satisfactory to them, and Parent or the Surviving Corporation shall pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received; provided, that Parent shall be
obligated pursuant to this paragraph (b) to pay for only two firms of counsel
for all Indemnified Parties in any jurisdiction, (ii) the Indemnified Parties
will cooperate in the defense of any such Litigation, and (iii) neither Parent
nor the Surviving Corporation shall be liable for any settlement effected
without its prior written consent or have any obligation hereunder to any
Indemnified Party when and if a court of competent jurisdiction shall determine,
and such determination shall have become final, that the indemnification of such
Indemnified Party in the manner contemplated hereby is prohibited by applicable
Law.

                  (c) If either Parent or the Surviving Corporation or any of
their respective successors or assigns shall consolidate with or merge into any
other Person and shall not be the continuing or surviving Person of such
consolidation or merger or shall transfer all or substantially all of its Assets
to any Person, then and in each case, proper provision shall be made so that the
successors and assigns of Parent or the Surviving Corporation, as the case may
be, shall assume the obligations set forth in this Section 8.12.

                  (d) Parent shall pay all reasonable costs, including
attorneys' fees, that may be incurred by any Indemnified Party in enforcing the
indemnity and other obligations provided for in this Section 8.12.

                  (e) The provisions of this Section 8.12 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party and his or
her heirs and representatives.

         8.13 Filing of Reports by Parent. During the six-month period following
the Effective Time, Parent shall use its commercially reasonable best efforts to
timely file all SEC Documents required to be filed by it and will issue press
releases concerning earnings in accordance with its established practice. Parent
agrees, for a period of three years after the Effective Time of the Merger, to
file on a timely basis all reports required to be filed by it pursuant to
Section 13 of the Securities Exchange Act of 1934, as amended, so that the
public information provisions of Rule 145(d) promulgated by the SEC as the same
are presently in effect will be available to the shareholders of Subject Company
in the event such shareholders desire to transfer any shares of Parent issued
pursuant to the Merger.

         8.14 Voting Agreement. Each of Subject Company's directors shall enter
into a voting agreement whereby each agrees to vote all stock of Subject
Company, owned of record or over which such director has voting control, in
favor of the Merger at the meeting of shareholders of Subject Company called for
the purpose of approving the Merger.

         8.15 Employment Agreement. Parent and Merger Subsidiary agree to cause
Union Planters Bank, National Association to enter into a employment agreements,
no later than the Closing Date, with Thomas W. Smith and Patrick M. Guidry,
respectively, which agreements shall be substantially in the form of Exhibit 4
attached hereto.

warranties of Subject Company set forth in Sections 5.1, 5.2, 5.3, 5.19 and 5.20

breach of any representation or warranty contained in this Agreement under the
applicable standard set forth in Section 9.2(a) of this Agreement in the case of

an inaccuracy of any representation or warranty of the other Party contained in
this Agreement which cannot be or has not been cured within 30 days after the

inaccuracy would provide the terminating Party the ability to refuse to
consummate the Merger under the applicable standard set forth in Section 9.2(a)

Agreement in the case of Parent; or

                  (c) By the Board of Directors of Parent or the Board of

of any covenant or other agreement contained in this Agreement) in the event of

this Agreement which cannot be or has not been cured within 30 days after the
giving of written notice to the breaching Party of such breach; or

                  (d) By the Board of Directors of Parent or the Board of
Directors of Subject Company in the event (i) any Consent of any Regulatory

                  (e) By the Board of Directors of Parent or the Board of
Directors of Subject Company in the event that the Merger shall not have been
consummated by March 31, 1999, if the failure to consummate the transactions
contemplated hereby on or before such date is not caused by any willful breach
of this Agreement by the Party electing to terminate pursuant to this Section
10.1(e);

<PAGE>   140




                  (f) By the Board of Directors of Parent or the Board of
Directors of Subject Company in the event that any condition to Closing set
forth in Article 9 hereof cannot be met by March 31, 1999 and has not been
waived by each Party in whose favor such condition inures; provided that the
inability to satisfy such condition to Closing on or before March 31, 1999 is
not caused by any willful breach of this Agreement by the Party electing to
terminate pursuant to this Section 10.1(f); or

                  (g) By the Board of Directors of Subject Company upon written
notice to Parent at any time during the ten-day period commencing two days after

                                    a. the Average Closing Price shall be less
                  than the product of (i) 0.80 and (ii) the Starting Price; and

                                    b. (i) the quotient obtained by dividing the
                  Average Closing Price by the Starting Price (such number being
                  referred to herein as the "UPC Ratio") shall be less than (ii)
                  the quotient obtained by dividing the Index Price on the
                  Determination Date by the Index Price on the Starting Date and
                  subtracting 0.15 from the quotient in this clause (2)(ii)
                  (such number being referred to herein as the "Index Ratio");
                  subject, however, to the following three sentences. If Subject
                  Company refuses to consummate the Merger pursuant to this
                  Section 10.1(g), it shall give prompt written notice thereof
                  to Parent; provided, that such notice of election to terminate
                  may be withdrawn at any time within the aforementioned ten-day
                  period. During the five-day period commencing with its receipt
                  of such notice, Parent shall have the option to elect to
                  increase the Exchange Ratio to equal the lesser of (i) the
                  quotient obtained by dividing (1) the product of 0.80, the
                  Starting Price, and the Exchange Ratio (as then in effect) by
                  (2) the Average Closing Price, and (ii) the quotient obtained
                  by dividing (1) the product of the Index Ratio and the
                  Exchange Ratio (as then in effect) by (2) the UPC Ratio. If
                  Parent makes an election contemplated by the preceding
                  sentence, within such five-day period, it shall give prompt
                  written notice to Subject Company of such election and the
                  revised Exchange Ratio, whereupon no termination shall have
                  occurred pursuant to this Section 10.1(g) and this Agreement
                  shall remain in effect in accordance with its terms (except as
                  the Exchange Ratio shall have been so modified), and any
                  references in this Agreement to "Exchange Ratio" shall
                  thereafter be deemed to refer to the Exchange Ratio as
                  adjusted pursuant to this Section 10.1(g).

                  For purposes of this Section 10.1(g), the following terms

                                    ARTICLE 3
                           MANNER OF CONVERTING SHARES

         3.1 Conversion of Shares. Subject to the provisions of this Article 3
(and Article 3 of the Agreement), at the Effective Time, by virtue of the Merger
and without any action on the part of Parent, Merger Subsidiary, Subject
Company, or the shareholders of any of the foregoing, the shares of the
constituent corporations shall be converted as follows:

                  (a) Each share of Parent Capital Stock, including any
associated Parent Rights, issued and outstanding immediately prior to the
Effective Time shall remain issued and outstanding from and after the Effective
Time.

                  (b) Each share of Merger Subsidiary Common Stock issued and
outstanding immediately prior to the Effective Time shall remain issued and
outstanding and shall represent one share of common stock of the Surviving
Corporation from and after the Effective Time.

                  (c) Except for Dissenting Shares, each share of Subject
Company Common Stock (excluding shares held by Subject Company, any Subject
Company Subsidiary, Parent or any Parent Subsidiary, in each case other than in
a fiduciary capacity or as a result of debts previously contracted) issued and
outstanding at the Effective Time shall cease to be outstanding and shall be
converted into and exchanged for the right to receive 2.83 shares of Parent
Common Stock (subject to possible adjustment as set forth in Section 3.2 of the
Agreement, the "Exchange Ratio"). Pursuant to the Parent Rights Agreement, each
share of Parent Common Stock issued in connection with the Merger upon
conversion of Subject Company Common Stock shall be accompanied by a Parent
Right.

                  (d) Dissenting Shares shall not be converted pursuant to
Section 3.1(c) in the Merger but, at and after the Effective Time, shall
represent only the right to receive payment in accordance with the applicable
provisions of Section 131 of the LBCL. If a holder of Dissenting Shares becomes
ineligible for payment under Section 131 of the LBCL, then such holder's
Dissenting Shares shall cease to be Dissenting Shares and shall be converted in
the manner set forth in Section 3.1(c) effective as of the Effective Time.

         3.2 Anti-Dilution Provisions. In the event Parent changes the number of
shares of Parent Common Stock issued and outstanding after the date of this Plan
of Merger and prior to the Effective Time as a result of a stock split, stock
dividend, subdivision, reclassification, conversion or similar recapitalization
with respect to such stock and the record date therefor (in the case of a stock
dividend) or the effective date thereof (in the case of a stock split,
subdivision, reclassification, conversion or similar recapitalization for which
a record date is not established) shall be prior to the Effective Time, the
Exchange Ratio shall be proportionately adjusted.

         3.3 Shares Held by Subject Company or Parent. Each of the shares of
Subject Company Common Stock held by Subject Company, any Subject Company
Subsidiary, Parent or any Parent Subsidiary, in each case other than in a
fiduciary capacity or as a result of debts previously contracted, shall be
canceled and retired at the Effective Time and no consideration shall be issued
in exchange therefor.

         3.4 Fractional Shares. Notwithstanding any other provision of this Plan
of Merger, each holder of shares of Subject Company Common Stock exchanged
pursuant to the Merger who would otherwise have been entitled to receive a
fractional share of Parent Common Stock (after taking into account all
certificates delivered by such holder which, immediately prior to the Effective
Time, represented shares of Subject Company Common Stock 


                   LaPlace Bancshares - Plan of Merger Page 2


<PAGE>   154

(each a "Subject Company Certificate")) shall receive, in lieu thereof, cash
(without interest) in an amount equal to such fractional share of Parent Common
Stock multiplied by the closing price of Parent Common Stock on the
NYSE-Composite Transactions List (as reported by The Wall Street Journal or, if
not reported thereby, any other authoritative source reasonably selected by
Parent) on the last trading day preceding the Effective Time. No such holder
will be entitled to dividends, voting rights, or any other rights as a
shareholder in respect of any fractional shares.

                                    ARTICLE 4
                               EXCHANGE OF SHARES

         4.1 Exchange Procedures. As soon as reasonably practicable after the
Effective Time, Parent and Subject Company shall cause the exchange agent
selected by Parent (the "Exchange Agent") to mail to each holder of record of a
Subject Company Certificate appropriate transmittal materials (which shall
specify that delivery shall be effected, and risk of loss and title to the
Subject Company Certificates shall pass, only upon proper delivery of such
Subject Company Certificates to the Exchange Agent). Subject Company shall have
the right to review and approve the transmittal materials. The Exchange Agent
may establish reasonable and customary rules and procedures in connection with
its duties, provided such rules and procedures do not have the effect of
unreasonably delaying or limiting or eliminating the obligation of Parent and/or
Merger Subsidiary to deliver the consideration contemplated by Article 3 of this
Plan of Merger. After the Effective Time, each holder of shares of Subject
Company Common Stock (other than Dissenting Shares or shares to be canceled
pursuant to Section 3.3 of this Plan of Merger) issued and outstanding at the
Effective Time shall surrender the certificate or certificates representing such
shares to the Exchange Agent and shall promptly upon surrender thereof receive
in exchange therefor the consideration provided in Section 3.1(c) of this Plan
of Merger, together with all undelivered dividends and other distributions, if
any, in respect of such shares (without interest thereon) pursuant to Section
4.2 of this Plan of Merger. To the extent required by Section 3.4 of this Plan
of Merger, each holder of shares of Subject Company Common Stock issued and
outstanding at the Effective Time also shall receive, upon surrender of the
certificate or certificates representing such shares, cash in lieu of any
fractional share of Parent Common Stock to which such holder may be otherwise
entitled (without interest). Parent shall not be obligated to deliver the
consideration to which any former holder of Subject Company Common Stock is
entitled as a result of the Merger until such holder surrenders such holder's
Subject Company Certificates for exchange as provided in this Section 4.1 or in
Section 4.2 hereof. The Subject Company Certificates so surrendered shall be
duly endorsed as the Exchange Agent may reasonably require. Any other provision
of the Agreement or this Plan of Merger notwithstanding, neither Parent, Merger
Subsidiary nor the Exchange Agent shall be liable to a holder of Subject Company
Common Stock for any amounts paid or property delivered in good faith to a
public official pursuant to any applicable abandoned property Law.

         4.2 Rights of Former Subject Company Shareholders. At the Effective 
Time, other than with respect to Dissenting Shares, the stock transfer books of
Subject Company shall be closed as to holders of Subject Company Common Stock
immediately prior to the Effective Time and no transfer of Subject Company
Common Stock by any such holder shall thereafter be made or recognized. Until
surrendered for exchange in accordance with the provisions of Section 4.1 of
this Plan of Merger, each certificate theretofore representing shares of Subject
Company Common Stock (other than Dissenting Shares or shares to be canceled
pursuant to Section 3.3 of this Plan of Merger) shall from and after the
Effective Time represent for all purposes only the right to receive the
consideration provided in Sections 3.1(c) and 3.4 of this Plan of Merger in
exchange therefor, subject, however, to the Surviving Corporation's obligations
to pay any dividends or make any other distributions with a record date prior to
the Effective Time which have been declared or made by Subject Company in
respect of such shares of Subject Company Common Stock in accordance with the
terms of this Plan of Merger and which remain unpaid at the Effective Time. In
addition, whenever a dividend or other distribution is declared by Parent on the
Parent Common Stock, the record date for which is at or after the Effective
Time, the declaration shall include dividends or other distributions on all
shares of Parent Common Stock issuable pursuant to this Plan of Merger, but no
dividend or other distribution payable to the holders of record of Parent Common
Stock as of any time subsequent to the Effective Time shall be delivered to the
holder of any certificate representing shares of Subject Company Common Stock
issued and outstanding at the Effective Time until such holder surrenders such
certificate for exchange as

                   LaPlace Bancshares - Plan of Merger Page 3


<PAGE>   155

provided in Section 4.1 of this Plan of Merger. However, upon surrender of such
Subject Company Common Stock certificate, both a Parent Common Stock certificate
and any undelivered dividends and other distributions payable hereunder (without
interest) shall be delivered and paid with respect to each share represented by
such certificate. In the event any Subject Company Common Stock 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 reasonably required by Parent, the posting by such person of a
bond in such amount as Parent may reasonably direct as indemnity against any
claim that may be made against it with respect to such certificate, the Exchange
Agent shall issue in exchange for such lost, stolen or destroyed certificate the
shares of Parent Common Stock and cash in lieu of fractional shares and
dividends and other distributions deliverable in respect thereof pursuant to
this Plan of Merger.

                                    ARTICLE 5
                                  MISCELLANEOUS

         5.1 Conditions Precedent. Consummation of the Merger by Merger
Subsidiary shall be conditioned on the satisfaction of or waiver by Parent of

Agreement. Consummation of the Merger by Subject Company shall be conditioned on
the satisfaction of, or waiver by Subject Company of, the conditions precedent

be amended by a subsequent writing signed by each of the Parties upon the
approval of the Boards of Directors of each of the Parties, whether before or

Company Common Stock, there shall be made no amendment that modifies in any
material respect the consideration to be received by the Subject Company
shareholders.

         5.4 Assignment. Except as expressly contemplated hereby, neither this
Plan of Merger nor the Agreement, nor any of the rights, interests, or
obligations hereunder or thereunder shall be assigned by any Party hereto
(whether by operation of Law or otherwise) without the prior written consent of
the other Parties. Subject to the preceding sentence, the Agreement and this
Plan of Merger will be binding upon, inure to the benefit of and be enforceable
by the Parties and their respective successors and assigns.

         5.5 Governing Law. This Plan of Merger shall be governed by and
construed in accordance with the Laws of the State of Tennessee, without regard
to any applicable conflicts of Laws.

together shall constitute one and the same document.

                               AFFILIATE AGREEMENT


Union Planters Corporation
7130 Goodlett Farms Parkway
Memphis, Tennessee  38108
Attention:  Jackson W. Moore, President
and Chief Operating Officer

Gentlemen:

         The undersigned is a shareholder of LaPlace Bancshares, Inc., ("Subject
Company") a corporation organized and existing under the laws of the State of
Louisiana, and will become a shareholder of Union Planters Corporation
("Parent") pursuant to the transactions described in the Agreement and Plan of
Merger, dated as of July 1, 1998 (the "Agreement"), by and between Parent, Union
Planters Holding Corporation ("Merger Subsidiary"), and Subject Company. Under
the terms of the Agreement, Subject Company will be merged with and into Merger
Subsidiary (the "Merger"), and shares of the $1.00 par value common stock of
Subject Company ("Subject Company Common Stock") will be converted into and
exchanged for shares of the $5.00 par value common stock of Parent ("Parent
Common Stock"). This Affiliate Agreement represents an agreement between the
undersigned and Parent regarding rights and obligations of the undersigned in
connection with the shares of Parent Common Stock to be received by the
undersigned as a result of the Merger. Except as otherwise provided herein,
capitalized terms set forth below shall have the meanings ascribed thereto in
the Agreement.

         In consideration of the Merger and the mutual covenants contained
herein, the undersigned and Parent hereby agree as follows:

         1. Affiliate Status. The undersigned understands and agrees that as to
Subject Company the undersigned may be deemed to be an "affiliate" under Rule
145(c) as defined in Rule 405 of the Rules and Regulations of the Securities and
Exchange Commission ("SEC") under the Securities Act of 1933, as amended ("1933
Act"), and the undersigned anticipates that the undersigned may be deemed to be
such an "affiliate" at the time of the Merger.

         2. Initial Restriction on Disposition. The undersigned agrees that the
undersigned will not sell, transfer, or otherwise dispose of the undersigned's
interest in, or reduce the under-signed's risk relative to, any of the shares of
Parent Common Stock into which the undersigned's shares of Subject Company
Common Stock are converted upon consummation of the Merger until such time as
the requirements of SEC Accounting Series Release Nos. 130 and 135 ("ASR 130 and
135") have been met. The undersigned understands that ASR 130 and 135 relate to
publication of financial results of post-Merger combined operations of Parent
and Subject Company. Parent agrees that it will publish such results within 45
days after the end of the first fiscal quarter of Parent containing the required
period of post-Merger combined operations and that it will notify the
undersigned promptly following such publication.

         3. Covenants and Warranties of Undersigned. The undersigned represents,
warrants, and agrees that:

         (a) During the 30 days immediately preceding the Effective Time of the
Merger, the undersigned will not sell, transfer or otherwise dispose of the
undersigned's interest in, or reduce the undersigned's risk relative to, any of
the shares of Subject Company Common Stock beneficially owned by the undersigned
as of the date of the Subject Company Shareholders' Meeting held to approve the
Merger.

                 LaPlace Bancshares - Affiliate Agreement Page 1


<PAGE>   158





         (b) The Parent Common Stock received by the undersigned as a result of
the Merger will be taken for the undersigned's own account and not for others,
directly or indirectly, in whole or in part.

         (c) Parent has informed the undersigned that any distribution by the
undersigned of Parent Common Stock has not been registered under the 1933 Act
and that shares of Parent Common Stock received pursuant to the Merger can only
be sold by the undersigned (1) following registration under the 1933 Act, or (2)
in conformity with the volume and other requirements of Rule 145(d) promulgated
by the SEC as the same now exists or may hereafter be amended, or (3) to the
extent some other exemption from registration under the 1933 Act might be
available. The undersigned understands that, except as set forth in the
Agreement and in paragraph 6 hereof, Parent is under no obligation to file a
registration statement with the SEC covering the disposition of the
undersigned's shares of Parent Common Stock or to take any other action
necessary to make compliance with an exemption from such registration available.

         (d) The undersigned will register, and will cause each of the other
parties whose shares may be deemed to be beneficially owned by the undersigned
pursuant to Section 8 hereof to have all shares of Subject Company Common Stock
beneficially owned by the undersigned registered in the name of the undersigned
or such parties, as applicable, prior to the Effective Date of the Merger and
not in the name of any bank, broker-dealer, nominee, or clearinghouse.

         (e) The undersigned is aware that Parent intends to treat the Merger as
a tax-free reorganization under Section 368 of the Internal Revenue Code
("Code") for federal income tax purposes. The undersigned agrees to treat the
transaction in the same manner as Parent for federal income tax purposes. The
undersigned acknowledges that Section 1.368-1(b) of the Income Tax Regulations
requires "continuity of interest" in order for the Merger to be treated as
tax-free under Section 368 of the Code. This requirement is satisfied if, taking
into account those Subject Company shareholders who receive cash in exchange for
their stock, who receive cash in lieu of fractional shares, or who dissent from
the Merger, there is no plan or intention on the part of the Subject Company
shareholders to sell or otherwise dispose of the Parent Common Stock to be
received in the Merger.

         4. Restrictions on Transfer. The undersigned understands and agrees
that stop order instructions with respect to the shares of Parent Common Stock
received by the undersigned pursuant to the Merger will be given to Parent's
transfer agent and that there will be placed on the certificates for such
shares, or shares issued in substitution thereof, a legend stating in substance:

         "The shares represented by this certificate were issued pursuant to a
         business combination which is accounted for as a "pooling-of-interests"
         and may not be sold, nor may the owner thereof reduce his risks
         relative thereto in any way, until such time as Union Planters
         Corporation ("Parent") has published the financial results covering at
         least 30 days of combined operations after the effective date of the
         merger through which the business combination was effected. In
         addition, the shares represented by this certificate may not be sold,
         transferred, or otherwise disposed of except or unless (1) covered by
         an effective registration statement under the Securities Act of 1933,
         as amended, (2) in accordance with (i) Rule 145(d) (in the case of
         shares issued to an individual who is not an affiliate of Parent) or
         (ii) Rule 144 (in the case of shares issued to an individual who is an
         affiliate of Parent) of the Rules and Regulations of such Act, or (3)
         in accordance with a legal opinion satisfactory to counsel for Parent
         that such sale or offer is otherwise exempt from the registration
         requirements of such Act."

         Such legend will also be placed on any certificate representing Parent
securities issued subsequent to the original issuance of the Parent Common Stock
pursuant to the Merger as a result of any exchange of such shares or any stock
dividend, stock split, or other recapitalization as long as the Parent Common
Stock issued to the undersigned pursuant to the Merger has not been transferred
in such manner to justify the removal of the legend therefrom. Upon the request
of the undersigned, Parent shall cause the certificates representing the shares
of Parent Common Stock issued to the undersigned in connection with the Merger
to be reissued free of any legend relating

                 LaPlace Bancshares - Affiliate Agreement Page 2


<PAGE>   159


to restrictions on transfer by virtue of ASR 130 and 135 as soon as practicable
after the requirements of ASR 130 and 135 have been met. In addition, if the
provisions of Rules 144 and 145 are amended to delete restrictions applicable to
the Parent Common Stock received by the undersigned pursuant to the Merger, or
at the expiration of the restrictive period set forth in Rule 145(d), Parent,
upon the request of the undersigned, will cause the certificates representing
the shares of Parent Common Stock issued to the undersigned in connection with
the Merger to be reissued free of any legend relating to the restrictions set
forth in Rules 144 and 145(d) upon receipt by Parent of an opinion of its
counsel to the effect that such legend may be removed.

         5. Understanding of Restrictions on Dispositions. The undersigned has
carefully read the Agreement and this Affiliate Agreement and discussed their
requirements and impact upon his ability to sell, transfer, or otherwise dispose
of the shares of Parent Common Stock received by the undersigned, to the extent
he believes necessary, with his counsel or counsel for Subject Company.

         6. Filing of Reports by Parent. Parent agrees, for a period of three
years after the Effective Time of the Merger, to file on a timely basis all
reports required to be filed by it pursuant to Section 13 of the Securities
Exchange Act of 1934, as amended, so that the public information provisions of
Rule 145(d) promulgated by the SEC as the same are presently in effect will be
available to the undersigned in the event the undersigned desires to transfer
any shares of Parent Common Stock issued to the undersigned pursuant to the
Merger.

         7. Transfer Under Rule 145(d). If the undersigned desires to sell or
otherwise transfer the shares of Parent Common Stock received by him in
connection with the Merger at any time during the restrictive period set forth
in Rule 145(d), the undersigned will provide the necessary representation letter
to the transfer agent for Parent Common Stock together with such additional
information as the transfer agent for Parent Common Stock may reasonably
request. If Parent's counsel concludes that such proposed sale or transfer
complies with the requirements of Rule 145(d), Parent shall cause such counsel
to provide such opinions as may be necessary to Parent's transfer agent so that
the undersigned may complete the proposed sale or transfer.

         8. Acknowledgments. The undersigned recognizes and agrees that the
foregoing provisions also apply to all shares of the capital stock of Subject
Company and Parent received by him in connection with the Merger that are deemed
to be beneficially owned by the undersigned pursuant to applicable federal
securities laws, which the undersigned agrees may include, without limitation,
shares owned or held in the name of (i) the undersigned's spouse, (ii) any
relative of the undersigned or of the undersigned's spouse who has the same home
as the undersigned, (iii) any trust or estate in which the undersigned, the
undersigned's spouse, and any such relative collectively own at least a 10%
beneficial interest or of which any of the foregoing serves as trustee,
executor, or in any similar capacity, and (iv) any corporation or other
organization in which the undersigned, the undersigned's spouse and any such
relative collectively own at least 10% of any class of equity securities or of
the equity interest. The undersigned further recognizes that, in the event that
the undersigned is a director or officer of Parent or becomes a director or
officer of Parent upon consummation of the Merger, among other things, any sale
of Parent Common Stock by the undersigned within a period of less than six
months following the Effective Time of the Merger may subject the undersigned to
liability pursuant to Section 16(b) of the Securities Exchange Act of 1934, as
amended.

         9. Miscellaneous. This Affiliate Agreement is the complete agreement
between Parent and the undersigned concerning the subject matter hereof. Any
notice required to be sent to any party hereunder shall be sent by registered or

                          INDEPENDENT AUDITOR'S REPORT






The Board of Directors and Stockholders
LaPlace Bancshares, Inc.
LaPlace, Louisiana




We have audited the accompanying consolidated statements of financial condition
of LaPlace Bancshares, Inc. and Subsidiary as of December 31, 1997 and 1996, and
the related consolidated statements of income, changes in stockholders' equity,
and cash flows for the years then ended. These 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 audits 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 consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of LaPlace
Bancshares, Inc. and Subsidiary at December 31, 1997 and 1996, and the results
of their operations and their cash flows for the years then ended in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                     YEARS ENDED DECEMBER 31, 1997 AND 1996

A.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF OPERATIONS

Principles of Consolidation and Nature of Operations

         The consolidated financial statements include the accounts of LaPlace
Bancshares, Inc. and its wholly-owned subsidiary, Bank of LaPlace of St. John
the Baptist Parish, Louisiana, a corporation, (collectively, the Bank) after
elimination of all material intercompany transactions and balances.

         The Bank provides a variety of financial services to individuals and
businesses primarily in St. John the Baptist Parish and surrounding parishes.
The Bank's office is located in LaPlace, Louisiana. The Bank's primary lending
products are commercial and mortgage loans; the primary deposit products are
savings accounts, certificates of deposit, and checking accounts. The Bank
operates under a state bank charter. As a state bank, the Bank is subject to
regulation by the Office of Financial Institutions of the State of Louisiana and
the Federal Deposit Insurance Corporation.

Basis of Financial Statement Presentation and Use of Estimates

         The consolidated financial statements have been prepared in conformity
with generally accepted accounting principles. In preparing the consolidated
financial statements, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities as of the date of the financial statements and
the reported amounts of revenues and expenses for the reporting period.
Actual results could differ from those estimates.

         Material estimates that are particularly susceptible to significant
changes relate to the determination of the allowance for loan losses and the
valuation of other real estate owned. Management determines the adequacy of the
allowance for loan losses based upon reviews of individual loans, recent loss
experience, current economic conditions, the risk characteristics of various
categories of loans, and other pertinent factors. In connection with the
determination of the allowance for loan losses and the valuation of other real
estate owned, management obtains independent appraisals for significant
collateral.

         A significant portion of the Bank's loans are secured by residential
real estate mortgages located in St. John the Baptist Parish. In addition, other
real estate owned is located in this same market. The Bank's loan portfolio and
the recovery of the carrying amount of other real estate owned are susceptible
to changes in local market conditions.

         While management uses available information to recognize losses on
loans and to value other real estate owned, future additions to the allowance or
changes to the valuation of other real estate owned may be necessary based on
changes in local economic conditions. In addition, regulatory agencies, as an
integral part of their examination process, periodically review the Bank's
allowance for loan losses and valuation of other real estate owned. Such
agencies may require the Bank to recognize additions to the allowance or changes
to the valuation of other real estate owned based on their judgments about
information available to them at the time of their examination. For statutory
purposes, other real estate owned is required to be written off after a period
of time and certain real estate has been written down under this method. Because
of these factors, it is reasonably possible that the estimated allowance for
loan losses or valuation of other real estate may change materially in the near
term. However, the amount of change that is reasonably possible cannot be
estimated.

Investment Securities

         Debt securities are classified in two categories and accounted for as
follows:

                  Securities Held to Maturity - Securities for which the Bank
                  has the positive intent and ability to hold to maturity are
                  reported at cost, adjusted for amortization of premiums and
                  accretion of discounts which are recognized in interest income
                  using a method over the period to maturity which approximates
                  the interest method.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)

                  Securities Available for Sale - Securities that the Bank has
                  not classified as held to maturity are classified as
                  securities available for sale and reported at fair value.
                  Unrealized gains and losses, net of income tax, are excluded
                  from earnings and reported in a separate component of equity
                  until realized.

         The Bank's investment policy precludes the trading of securities, i.e.,
the purchase of securities with the intent to resell in the near term. The Bank
classifies securities as held to maturity or available for sale based on
management's intent at the time of the purchase.

         Declines in the fair value of individual held to maturity and available
for sale securities below their cost that are other than temporary result in
write-downs of the individual securities to their fair value. Such write-downs,
if any, would be included in earnings as realized losses.

         Gains and losses on the sale of securities available for sale are
determined using the specific identification method.

Premises and Equipment

         Premises and equipment are stated at cost less accumulated depreciation
and amortization.

         Depreciation and amortization are computed using the straight-line
method using the following estimated useful lives:

<TABLE>
         <S>                                <C>
         Building                               40 years
         Building improvements              8 - 25 years
         Furniture, fixtures and equipment  3 - 25 years
</TABLE>

         Maintenance and repairs are expensed as incurred while major additions
and improvements are capitalized. Gains and losses on dispositions are included
in current operations.

Loans and Loans Held For Sale

         Loans receivable that management has the intent and ability to hold for
the foreseeable future or until maturity or payoff are reported at their
outstanding principal amounts less unearned discounts and the allowance for loan
losses.

         Interest income generally is not accrued on loans when, in management's
opinion, the circumstances are such that interest may not be collectible. It is
the general policy of the Bank to discontinue the accrual of interest when
principal or interest payments are delinquent 90 days or more, and to reverse
from income any unpaid amounts previously accrued on those loans. Cash payments
subsequently received are applied to interest and principal based on
management's judgment.

         The loan portfolio is short-term in nature. Loan fees and certain
direct origination costs are recognized and included in current operations.

         The Bank originates single-family residential loans primarily for sale
into the secondary market. By originating such loans for sale and generally
obtaining a commitment for the purchase of such loans at the time that the loan
applications are approved, the Bank avoids the interest rate risk associated
with holding fixed-rate mortgage loans.

         Mortgage loans originated and intended for sale in the secondary market
are carried at the lower of cost or estimated market value in the aggregate. Net
unrealized losses are recognized through a valuation allowance by charges to
income.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)

Allowance for Loan Losses

         The balance in the allowance for loan losses is based on an analysis by
management of the collectibility of the loan portfolio and is increased by
charges to income and decreased by charge-offs (net of recoveries). It reflects
an amount which, in management's judgment, is adequate to provide for potential
loan losses after giving consideration to known and inherent risks in the
portfolio, adverse situations that may affect the borrower's ability to repay,
the estimated value of any underlying collateral, and current economic
conditions.

Other Real Estate

         Real estate properties acquired through, or in lieu of, loan
foreclosure are initially recorded at the lower of the Bank's carrying amount or
fair value less estimated selling cost at the date of foreclosure. Any
write-downs based on the asset's fair value at the date of acquisition are
charged to the allowance for loan losses. Valuations are periodically performed
by management, and any subsequent write-downs are recorded as a charge to
operations, if necessary, to reduce the carrying value of a property to the
lower of its cost or fair value less costs to sell.

Income Taxes

         LaPlace Bancshares, Inc. and its subsidiary file a consolidated federal
income tax return. Benefit from or provision for income tax is based on amounts
reported in the statement of income (after exclusion of non-taxable income such
as interest on state and municipal securities) and includes deferred taxes on
temporary differences in the recognition of income and expense for tax and
financial statement purposes. Deferred taxes are computed using the liability
method. Deferred income taxes result primarily from differences between the
bases of allowance for loan losses, accumulated depreciation, and other real
estate for financial and income tax reporting. The deferred tax assets and
liabilities represent the future tax return consequences of those differences,
which will either be taxable or deductible when the assets and liabilities are
recovered or settled. Income taxes are allocated between the parent and
subsidiary in proportion to their share of income or loss.

Cash and Cash Equivalents

         For purposes of reporting cash flows, cash and cash equivalents include
cash on hand, and amounts due from banks. The Bank considers all highly liquid
instruments purchased with a maturity of three months or less from the date of
acquisition to be cash equivalents.

         The Bank maintains cash balances at various financial institutions.
Accounts are insured by the Federal Deposit Insurance Corporation (FDIC) up to
$100,000. At various times in 1997 and 1996, the Bank had funds on deposit at
these institutions which were in excess of the insured amount. Deposits at the
Federal Home Loan Bank are not subject to insurance coverage.

Advertising

         The Bank expenses the production costs of advertising the first time
the advertising takes place, except for direct-response advertising which is
capitalized and amortized over its expected period of future benefits.
Advertising expense was $118,539 and $155,896 for 1997 and 1996. There was no
direct-response advertising in 1997 or 1996.

Net Income Per Share

         Earnings per common share is computed based on the weighted average
number of shares outstanding during the year.

                                   (Continued)

Derivative Financial Instruments

         All derivative financial instruments issued by the Bank are issued for
purposes other than trading. In the ordinary course of business, the Bank enters
into off-balance-sheet financial instruments consisting of commitments to extend
credit. Such financial instruments are recorded in the financial statements when
they are funded.

Reclassifications

         Certain reclassifications have been made to the 1996 financial
statements in order to conform to the 1997 presentation.

B.       INVESTMENT SECURITIES

The carrying amounts of investment securities as shown in the consolidated
statements of financial condition of the Bank and their approximate fair values

Advance from the Federal Home Loan
       Bank (FHLB), maturing January 2, 1998; interest
         rate of 6.8%.  Secured by specific investment
         securities with a carrying value of
         approximately $2,872,000 at December 31,
         1997                                               $3,082,000      $    --

         In addition to the above advance from the Federal Home Loan Bank, the
Bank has available Federal Funds lines of credit from two commercial banks to
manage its liquidity on a daily basis. The combined maximum amount available
under these two lines at December 31, 1997 is $3,500,000, and interest rates
fluctuate on a daily basis. At December 31, 1997 and 1996, the Bank had $25,000
outstanding under the lines of credit.

         All Federal Home Loan Bank of Dallas (FHLB) advances are secured by
first collateral mortgages on one to four family residential dwellings and the
FHLB capital stock and deposit account.

K.       COMMITMENTS AND CONTINGENT LIABILITIES

         In the normal course of business, the Bank is a party to financial
instruments with off-balance-sheet risk to meet the financing needs of its
customers. These financial instruments include commitments to extend credit,
line of credit arrangements on credit cards, standby letters of credit, and
financial guarantees. These instruments involve elements of credit and interest
rate risk in excess of the amount recognized in the accompanying consolidated
statements of financial condition. The Bank uses the same credit policies in
making commitments and conditional obligations as it does for amounts recognized
in the consolidated statements of financial condition.

         Financial instruments whose contract amounts represents credit risk
were approximately as follows:

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

Commitments to extend credit            $6,813,000      $6,150,000
Unused line of credit arrangements
   on credit cards                      $  567,000      $  573,000
Standby letter of credit                $   61,000      $   60,000
</TABLE>

         Commitments to extend credit and line of credit arrangements on credit
cards are agreements to lend to a customer as long as there is no violation of
any condition established in the contract. Such commitments generally have fixed
expiration dates or other termination clauses and may require payment of a fee.
Since many of the commitments are expected to expire without being drawn upon,
the total commitment amounts do not necessarily represent future cash
requirements. The Bank evaluates each customer's credit worthiness on a
case-by-case basis. The amount of collateral

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)

obtained, if deemed necessary by the Bank upon extension of credit, is based on
management's credit evaluation. Collateral held varies but may include accounts
receivable, inventory, property and equipment, and income-producing commercial
properties.

         Standby letters of credit are conditional commitments issued by the
Bank to guarantee the performance of a customer to a third party. Standby
letters of credit generally have fixed expiration dates or other termination
clauses and may require payment of a fee. The credit risk involved in issuing
letters of credit is essentially the same as that involved in extending loan
facilities to customers. The Bank's policy for obtaining collateral, and the
nature of such collateral, is essentially the same as those involved in making
commitments to extend credit.

         The Bank has not been required to perform on any financial guarantees
during the past two years. The Bank has not incurred any losses on its
commitments in either 1997 or 1996.

         The Bank has employment agreements with two executive officers. In
addition to their annual compensation, these agreements provide for special
payments to be made if there is a separation of employment under certain
conditions.

L.       LEASES

         The Subsidiary leases its main banking facilities under an operating
lease from the Parent Company. In June 1993, a new lease was negotiated, and the
term of the lease extends through June 2004. Rental income/expense of $229,200
for the years ended December 31, 1997 and 1996, have been eliminated in
consolidation.

         The Subsidiary subleases office space to a law firm under an operating
lease agreement. The law firm provides professional services to the Bank. The
operating sublease, which expired in August 1995 provided for monthly rental
payments of $3,000. The lease has continued on a month-to-month basis. Total
rental income received under this lease was $36,000 for 1997 and 1996.

         Additionally, the Subsidiary subleased another part of the building to
an unaffiliated investment company on a month-to-month basis. The sublessor
vacated the premises in July 1997.

         Total rental income from subleases was $36,700 and $37,200 for 1997 and
1996, and is included in non-interest income-other on the accompanying
consolidated statements of income.

M.       EMPLOYEE BENEFIT PLAN

         The Bank has a retirement savings 401(k) plan in which substantially
all employees may participate. The Bank matches employees' contributions based
on a percentage of salary contributed by participants. The Bank's expense for
the plan was $36,263 and $35,929 in 1997 and 1996.

N.       REGULATORY MATTERS

         The Subsidiary is subject to certain restrictions on the amount of
dividends that it may pay without prior regulatory approval. The Bank normally
restricts dividends to amounts requiring no prior regulatory approval. At
December 31, 1997, retained earnings of approximately $1,000,000 was available
for the payment of dividends without prior regulatory approval.

         The Bank is subject to various regulatory capital requirements
administered by its primary federal regulator, the Federal Deposit Insurance
Corporation (FDIC). Failure to meet the minimum regulatory capital requirements
can initiate certain mandatory, and possible additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under the regulatory capital adequacy guidelines
and the regulatory framework for prompt corrective action, the Bank must meet
specific capital guidelines involving quantitative measures of the Bank's
assets, liabilities, and certain off-balance-sheet items as calculated under
regulatory accounting practices. The Bank's capital amounts and classification
are also subject to qualitative judgments by the regulators about components,
risk weightings, and other factors.

                                   (Continued)

         Quantitative measures established by regulation to ensure capital
adequacy require the Bank to maintain minimum amounts and ratios (set forth in
the table below) of total risk-based capital and Tier I capital (as defined in
the regulations) to risk-weighted assets (as defined), and of Tier I capital (as
defined) to average assets (as defined) (leverage ratio). Management believes,
as of December 31, 1997, that the Bank meets all capital adequacy requirements
to which it is subject.

         As of December 31, 1997, the most recent notification from FDIC
categorized the Bank as well capitalized under the regulatory framework for
prompt corrective action. To be categorized as well capitalized, the Bank must
maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios
as disclosed in the table below. There are no conditions or events since the
notification that management believes have changed the Bank's prompt corrective
action category.

Chief Executive Officer
LaPlace Bancshares, Inc.

         Re:      Fairness Opinion Regarding the Proposed Acquisition of LaPlace
                  Bancshares, Inc., by Union Planters Corporation

Dear Directors:

Mercer Capital Management, Inc. ("Mercer Capital") has been retained by the
Board of Directors of LaPlace Bancshares, Inc. ("LaPlace") to issue a fairness
opinion regarding the financial terms for the proposed merger between LaPlace
and Union Planters Corporation ("UPC"). A representative of Mercer Capital
previously provided an oral, preliminary fairness opinion to the Board of
Directors on June 25, 1998. The fairness opinion is issued from a financial
point of view on behalf of LaPlace shareholders.

Under the terms of the Agreement and Plan of Merger ("the Agreement") by and
among Union Planters Corporation, Union Planters Holding Corporation, and
LaPlace Bancshares, Inc., dated July 1, 1998, LaPlace shall be merged with and
into Union Planters Holding Corporation, a wholly owned subsidiary of UPC. At
the Effective Time (as defined in the Agreement), each outstanding LaPlace
common share shall be converted into 2.83 UPC common shares. The Exchange Ratio
(as defined in the Agreement) is based upon a negotiated value of $159.88 per
share for LaPlace and the average closing price for UPC for the twenty trading
days ended June 24, 1998. The ultimate value of the merger to LaPlace
stockholders, however, will be contingent upon the market value of UPC's Common
Stock on the Effective Date.

We understand that the Merger is conditioned upon, among other things, receipt
of opinions to the effect that the Merger will qualify for treatment as a
tax-free reorganization and as a pooling of interests for accounting purposes.

Mercer Capital, as part of its investment banking and general valuation
businesses, is engaged to assist financial institutions and businesses in
merging with and acquiring other entities, and to value businesses and their
securities in connection with mergers and acquisitions, private placements,
corporate reorganization, estate tax matters, and other purposes. We have acted
as LaPlace's Financial Advisor in connection with, and have participated in
certain negotiations leading to, the Agreement.

As part of the engagement, representatives of Mercer Capital visited with
LaPlace management in LaPlace, Louisiana and with UPC management in Memphis,
Tennessee. Factors considered in rendering the opinion include:

         1.       The terms of the Agreement, dated July 1, 1998;

         2.       The process by which the Board solicited offers for LaPlace
                  from various regional bank holding companies and the
                  subsequent arms' length negotiations which occurred between
                  representatives of LaPlace and UPC;

         3.       The valuation analysis of LaPlace as prepared by Mercer
                  Capital;

         4.       An analysis of the estimated pro-forma changes in book value
                  per share, earnings per share, and dividends per share from
                  the perspective of the LaPlace shareholders;

         5.       A review of LaPlace's audited financial statements, internally
                  prepared financial statements, and certain regulatory
                  financial data for the fiscal years ended December 31, 1993,
                  1994, 1995, 1996, and 1997 and the quarters ended March 31,
                  June 30, and September 30, 1998;

         6.       A review of UPC's Annual Report to Shareholders and Annual
                  Reports on Form 10-K for each of the years ended December 31,
                  1995, 1996, and 1997 and quarterly financial information for
                  the quarters ended March 31, June 30, and September 30, 1998 
                  on Form 10-Q;

         7.       A review of UPC's historical trading price and volume on an
                  absolute basis and on a relative basis in comparisons to
                  companies deemed to be comparable to UPC;

         8.       A comparison of the financial terms, to the extent publicly
                  available, of certain acquisition transactions which we deemed
                  to be relevant for purposes of this opinion; and,

         9.       Tax consequences of the merger for LaPlace shareholders.

Mercer Capital neither compiled nor audited LaPlace's or UPC's financial
statements; nor have we independently verified the information reviewed. We have
relied upon such information as being complete and accurate in all material
respects. We have not made an independent valuation of the loan portfolio,
adequacy of the loan loss reserve or other assets or liabilities of either
institution.

Our opinion does not constitute a recommendation to any shareholder as to how
the shareholder should vote on the proposed merger; nor have we expressed any
opinion as to the prices at which any security of UPC or LaPlace might trade in
the future. The opinion is necessarily based on economic, market, financial and
other conditions as they exist on, and on the information made available to us,
as of the date of this letter.

Based upon our analysis of the proposed transaction, it is our opinion as of the
date hereof that the Exchange Ratio is fair from a financial point of view to
the common shareholders of LaPlace.



                                         Sincerely yours,

ss. 131. Rights of a shareholder dissenting from certain corporate actions

     A. Except as provided in subsection B of this section, if a corporation
has, by vote of its shareholders, authorized a sale, lease or exchange of all of
its assets, or has, by vote of its shareholders, become a party to a merger or
consolidation, then, unless such authorization or action shall have been given
or approved by at least eighty per cent of the total voting power, a shareholder
who voted against such corporate action shall have the right to dissent. If a
corporation has become a party to a merger pursuant to R.S. 12:112(H), the
shareholders of any subsidiaries party to the merger shall have the right to
dissent without regard to the proportion of the voting power which approved the
merger and despite the fact that the merger was not approved by vote of the
shareholders of any of the corporations involved.

     B. the right to dissent provided by this Section shall not exist in the
case of:

     (1) A sale pursuant to an order of a court having jurisdiction in the
premises.

     (2) A sale for cash on terms requiring distribution of all or substantially
all of the net proceeds to the shareholders in accordance with their respective
interests within one year after the date of the sale.

     (3) Shareholders holding shares of any class of stock which, at the record
date fixed to determine shareholders entitled to receive notice of and to vote
at the meeting of shareholders at which a merger or consolidation was acted on,
were listed on a national securities exchange, or were designated as a national
market system security on an inter-dealer quotation system by the National
Association of Securities Dealers, unless the articles of the corporation
issuing such stock provide otherwise or the shares of such shareholders were not
converted by the merger or consolidation solely into shares of the surviving or
new corporation.

     C. Except as provided in the last sentence of this subsection, any
shareholder electing to exercise such right of dissent shall file with the
corporation, prior to or at the meeting of shareholders at which such proposed
corporate action is submitted to a vote, a written objection to such proposed
corporate action, and shall vote his shares against such action. If such
proposed corporate action to be taken by the required vote, but by less than
eighty per cent of the total voting power, and the merger, consolidation or
sale, lease or exchange of assets authorized thereby be effected, the
corporation shall promptly thereafter give written notice thereof, by registered
mail, to each shareholder who filed such written objection to, and voted his
shares against, such action, at such shareholder's last address on the
corporation's records. Each such shareholder may, within twenty days after the
mailing of such notice to him, but not thereafter, file with the corporation a
demand in writing for the fair cash value of his shares as of the day before
such vote was taken, provided that he state in such demand the value demanded,
and a post office address to which the reply of the corporation may be sent, and
at the same time deposit in escrow in a chartered bank or trust company located
in the parish of the registered office of the corporation, the certificates
representing his shares, duly endorsed and transferred to the corporation upon
the sole condition that said certificates shall be delivered to the corporation
upon payment of the value of the shares determined in accordance 
<PAGE>   188






with the provisions of this section. With his demand the shareholder shall 
deliver to the corporation, the written acknowledgment of such bank or trust 
company that it so holds his certificates of stock. Unless the objection, 
demand and acknowledgment aforesaid be made and delivered by the shareholder 
within the period above limited, he shall conclusively be presumed to have 
acquiesced in the corporate action proposed to taken. In the case of a merger 
pursuant to R.S. 12:112(H), the dissenting shareholder need not file an 
objection with the corporation nor vote against the merger, but need only file 
with the corporation, within twenty days after a copy of the merger certificate 
was mailed to him, a demand in writing for the cash value of his shares as of 
the day before the certificate was filed with the secretary of state, state in 
such demand the value demanded and a post office address to which the 
corporation's reply may be sent, deposit the certificates representing his 
shares in escrow as hereinabove provided, and deliver to the corporation with 
his demand the acknowledgment of the escrow bank or trust company as 
hereinabove prescribed.

     D.     If the corporation does not agree to the value so stated and
demanded, or does not agree that a payment is due, it shall, within twenty days
after receipt of such demand and acknowledgment, notify in writing the
shareholder, at the designated post office address, of its disagreement, and
shall state in such notice the value it will agree to pay if any payment should
be held to be due; otherwise it shall be liable for, and shall pay to the
dissatisfied shareholder, the value demanded by him for his shares.

     E.     In case of disagreement as to such fair cash value, or as to whether
any payment is due, after compliance by the parties with the provisions of
subsections C and D of this section, the dissatisfied shareholder, within sixty
days after receipt of notice in writing of the corporation's disagreement, but
not thereafter, may file suit against the corporation, or the merged or
consolidated corporation, as the case may be, in the district court of the
parish in which the corporation or the merged or consolidated corporation, as
the case may be, has its registered office, praying the court to fix and decree
the fair cash value of the dissatisfied shareholder's shares as of the day
before such corporate action complained of was taken, and the court shall, on
such evidence as may be adduced in relation thereto, determine summarily whether
any payment is due, and, if so, such cash value and render judgement
accordingly. Any shareholder entitled to file such suit may, within such
sixty-day period but not thereafter, intervene as a plaintiff in such suit filed
by another shareholder, and recover therein judgement against the corporation
for the fair cash value of his shares. No order or decree shall be made by the
court staying the proposed corporation action, and any such corporate action may
be carried to completion notwithstanding any such suit. Failure of the
shareholder to bring suit, or to intervene in such a suit, within sixty days
after receipt of notice of disagreement by the corporation shall conclusively
bind the shareholder (1) by the corporation's statement that no payment is due,
or (2) if the corporation does not contend that no payment is due, to accept the
value of his shares as fixed by the corporation in its notice of disagreement.

     F.     When the fair value of the shares has been agreed upon between the
shareholder and corporation, or when the corporation has become liable for the
value demanded by the shareholder because of failure to give notice of
disagreement and of the value it will pay, or when the shareholder has become
bound to accept the value the corporation agrees is due because of his failure
to bring suit within sixty days after receipt of notice of the corporation's
disagreement, the action of the 
<PAGE>   189
shareholder to recover such value must be brought within five years from the
date the value was agreed upon, or the liability of the corporation became
fixed.

     G.  If the corporation or the merged or consolidated corporation, as the
case may be, shall, in its notice of disagreement, have offered to pay to the
dissatisfied shareholder on demand an amount in cash deemed by it to be the fair
cash value of his shares, and if, on the institution of a suit by the
dissatisfied shareholder claiming an amount in excess of the amount so offered,
the corporation, or the merged or consolidated corporation, as the case may be,
shall deposit in the registry of the court, there to remain until the final
determination of the cause, the amount so offered, then, if the amount finally
awarded such shareholder, exclusive of interest and costs, be more than the
amount offered and deposited as aforesaid, the costs of the proceeding shall be
taxed against the corporation, or the merged or consolidated corporation, as the
case may be; otherwise the costs of the proceeding shall be taxed against such
shareholder.

     H.  Upon filing a demand for the value of his shares, the shareholder shall
cease to have any of the rights of a shareholder except the rights accorded by
this section. Such a demand may be withdrawn by the shareholder at any time
before the corporation gives notice of disagreement, as provided in subsection D
of this section. After such notice of disagreement is given withdrawal of a
notice of election shall require the written consent of the corporation. If a
notice of election is withdrawn, or the proposed corporate action is abandoned
or rescinded, or a court shall determine that the shareholder is not entitled to
receive payment for his shares, or the shareholder shall otherwise lose his
dissenter's rights, he shall not have the right to receive payment for his
shares, his share certificates shall be returned to him (and, on his request,
new certificates shall be issued to him in exchange for the old ones endorsed to
the corporation), and he shall be reinstated to all his rights as a shareholder
as of the filing of his demand for value, including any intervening preemptive
rights, and the right to payment of any intervening dividend or other
distribution, or, if any such rights have expired or any such dividend or
distribution other than in cash has been completed, in lieu thereof, at the
election of the corporation, the fair value thereof in cash as determined by the
board as of the time of such expiration or completion, but without prejudice
otherwise to any corporate proceedings that may have been taken in the interim.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.          INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Restated Charter of the Registrant provides as follows:

TWELFTH:          INDEMNIFICATION OF CERTAIN PERSONS:

              To the fullest extent permitted by Tennessee law, the Corporation
may indemnify or purchase and maintain insurance to indemnify any of its
directors, officers, employees or agents and any persons who may serve at the
request of the Corporation as directors, officers, employees, trustees or agents
of any other corporation, firm, association, national banking association,
state-chartered bank, trust company, business trust, organization or any other
type of entity whether or not the Corporation shall have any ownership interest
in such entity. Such indemnification(s) may be provided for in the Bylaws, or by
resolution of the Board of Directors or by appropriate contract with the person
involved.

Article V, INDEMNIFICATION, of the Registrant's Amended and Restated Bylaws
provides as follows:

              The Corporation does hereby indemnify its directors and officers
to the fullest extent permitted by the laws of the State of Tennessee and by
ARTICLE TWELFTH of its Charter. The Corporation may indemnify any other person
to the extent permitted by the Charter and by applicable law.

              Indemnification of corporate directors and officers is governed by
Sections 48-18-501 through 48-18-509 of the Tennessee Business Corporation Act
(the "Act"). Under the Act, a person may be indemnified by a corporation against
judgments, fines, amounts paid in settlement and reasonable expenses (including
attorneys' fees) actually and necessarily incurred by him in connection with any
threatened or pending suit or proceeding or any appeal thereof (other than an
action by or in the right of the corporation), whether civil or criminal, by
reason of the fact that he is or was a director or officer of the corporation or
is or was serving at the request of the corporation as a director or officer,
employee or agent of another corporation of any type or kind, domestic or
foreign, if such director or officer acted in good faith for a purpose which he
reasonably believed to be in the best interest of the corporation and, in
criminal actions or proceedings only, in addition, had no reasonable cause to
believe that his conduct was unlawful. A Tennessee corporation may indemnify a
director or officer thereof in a suit by or in the right of the corporation
against amounts paid in settlement and reasonable expenses, including attorneys'
fees, actually and necessarily incurred as a result of such suit unless such
director or officer did not act in good faith or with the degree of diligence,
care and skill which ordinarily prudent men exercise under similar circumstances
and in like positions.

              A person who has been wholly successful, on the merits or
otherwise, in the defense of any of the foregoing types of suits or proceedings
is entitled to indemnification for the foregoing amounts. A person who has not
been wholly successful in any such suit or proceeding may be indemnified only
upon the order of a court or a finding that the director or officer met the
required statutory standard of conduct by (i) a majority vote of a disinterested
quorum of the


<PAGE>   191

Board of Directors, (ii) the Board of Directors based upon the written opinion
of independent legal counsel to such effect, or (iii) a vote of the
shareholders.

ITEM 22.   UNDERTAKINGS.

                  The undersigned Registrant hereby undertakes:

                  (1)      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 15(d) of the Securities Exchange Act of 1934 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.

                  (2)      That for purposes of determining any liability under 
the Securities Act of 1933, the information omitted from the form of prospectus
filed as part of this registration statement in reliance upon Rule 430A and
contained in a form of prospectus filed by the Registrant pursuant to Rule
424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part
of this registration statement as of the time it was declared effective.

                  (3)      That for the purpose of determining any liability 
under the Securities Act of 1933, each post-effective amendment that contains a
form of prospectus 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.

                  (4)      Insofar as indemnification for liabilities arising 
under the Securities Act of 1933 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 Securities
and Exchange Commission such indemnification is against public policy as
expressed in the 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 by such 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 Act and will
be governed by the final adjudication of such issue.

                  (5)      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 S-4, 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.

                  (6)      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.

                  (7)      That prior to any public reoffering of the securities
registered hereunder through the 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
