                         GONZALEZ, LOUISIANA 70707-1089

                                                                    May __, 1996

To Our Shareholders:

         You are cordially invited to attend a Special Meeting (the "Meeting")
of Shareholders of Bank of Gonzales Holding Company, Inc. ("Gonzales Holding")
to be held at [2:00 p.m]., local time, on May __, 1996 at the [Holiday Inn -
Gonzales at 1500 West Highway 30, Gonzales, Louisiana].

         At the Meeting you will be asked to consider and vote upon the
proposal to approve an Agreement and Plan of Merger (the "Merger Agreement"),
dated as of February 5, 1996, by and among Deposit Guaranty Corp., a
Mississippi corporation ("Deposit Guaranty"), Commercial National Corporation
("CNC"), a Louisiana corporation and a wholly-owned subsidiary of Deposit
Guaranty, and Citizens National Bank ("Citizens Bank"), a  national bank and a
wholly-owned subsidiary of CNC, on the one hand, and Gonzales Holding and its
wholly-owned subsidiary, Bank of Gonzales ("Gonzales Bank"), on the other hand,
pursuant to which (a) Gonzales Holding will merge into CNC (the "Holding
Company Merger") and Gonzales Bank will merge into Citizens Bank (the "Bank
Merger" and together with the Holding Company Merger, the "Mergers"), and (b)
each outstanding share of Gonzales Holding common stock will be converted into
shares of Deposit Guaranty common stock as more fully described in the
accompanying Proxy Statement/Prospectus.

         The affirmative vote of the holders of at least a majority of the
outstanding shares of common stock of Gonzales Holding must approve the Merger
Agreement.  Consummation of the Mergers also requires certain regulatory
approvals.

         The Board of Directors of Gonzales Holding believes the Mergers are in
the best interests of Gonzales Holding and its shareholders and unanimously
recommends that you vote for approval of the Merger Agreement.  The reasons for
such recommendation are set forth in the accompanying Proxy
Statement/Prospectus.  Furthermore, Gonzales Holding's financial advisor, Alex
Sheshunoff & Co. Investment Banking, has issued its opinion to the effect that,
as of the date of such opinion and based upon the considerations described
therein, the terms of the Mergers are fair, from a financial point of view, to
the shareholders of Gonzales Holding.

         We believe that the Mergers represent an exceptional opportunity for
Gonzales Holding shareholders 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 Mergers, you, as a
shareholder of Deposit Guaranty, will own common stock in a bank holding
company whose shares are actively traded.  Combining Gonzales Holding with
Deposit Guaranty through the Mergers should thus provide Gonzales Holding
shareholders with a continued equity interest in a larger, more diversified
banking company.

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

         All shareholders are invited to attend the Meeting in person.
However, in order to ensure that your shares will be represented at the
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 Meeting.
If you attend the Meeting in person, you may, if you wish, vote personally on
all matters brought before the Meeting.

                                           Very truly yours,


                                           D. Dale Gaudet

         The following is a brief summary of certain information contained
elsewhere in this Proxy Statement/ Prospectus and the documents incorporated
herein by reference.  This summary is necessarily incomplete and is subject to
and qualified in its entirety by reference to the more detailed information and

Statement/Prospectus by reference.  Certain capitalized terms used in this
summary are defined elsewhere in this Proxy Statement/Prospectus.

PURPOSE OF THE MEETING

         The purpose of the Meeting is to consider and vote upon a proposal to
approve an Agreement and Plan of Merger, dated February 5, 1996 (the "Merger
Agreement"),  by and among Deposit Guaranty Corp., a Mississippi corporation
("Deposit Guaranty"), its wholly-owned subsidiary, Commercial National
Corporation, a Louisiana corporation ("CNC"), and CNC's wholly-owned
subsidiary, Citizens National Bank, a national banking association ("Citizens
Bank"), on the one hand, and Bank of Gonzales Holding Company, Inc., a
Louisiana corporation ("Gonzales Holding") and its wholly-owned subsidiary,
Bank of Gonzales, a Louisiana state bank ("Gonzales Bank"), on the other hand,
pursuant to which, among other things, (a) Gonzales Holding will be merged into
CNC (the "Holding Company Merger"), (b) Gonzales Bank will be merged into
Citizens Bank (the "Bank Merger" and together with the Holding Company Merger,
the "Mergers"), and (c) on the effective date of the Mergers (the "Effective
Date"), each outstanding share of Gonzales Holding common stock, no par value
per share ("Gonzales Holding Common Stock"), will be converted into a number of
shares of common stock, no par value per share, of Deposit Guaranty ("Deposit
Guaranty Common Stock") determined by dividing 634,000 by the number of shares
of Gonzales Holding Common Stock outstanding on the date immediately preceding
the Effective Date.  As a result of the Mergers, the business and properties of

REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS

         The Gonzales Holding Board has unanimously approved the Mergers and
the Merger Agreement and has determined that the Mergers are in the best
interests of Gonzales Holding and its shareholders.  In approving the Mergers,
Gonzales Holding's directors considered among other factors the financial terms
of the transaction; the liquidity afforded to shareholders of Gonzales Holding
through ownership of a publicly traded stock; a review of the business and
prospects of Gonzales Holding and Deposit Guaranty; the federal income tax
consequences of the Mergers; the likelihood of the Mergers being approved by
regulatory authorities without undue conditions or delays; and an opinion from
Alex Sheshunoff & Co.  Investment Banking ("Sheshunoff") regarding the fairness
of the terms of the Mergers, from a financial point of view, to Gonzales
Holding 's shareholders.  THE GONZALES HOLDING BOARD OF DIRECTORS BELIEVES THE
MERGERS ARE IN THE BEST INTEREST OF GONZALES HOLDING 'S SHAREHOLDERS AND
UNANIMOUSLY RECOMMENDS THAT GONZALES HOLDING 'S SHAREHOLDERS VOTE FOR THE
APPROVAL OF THE MERGER AGREEMENT.

         The Board of Directors of Deposit Guaranty has approved the Merger
Agreement because it believes that the Merger will enhance Deposit Guaranty's
earnings capacity by enabling it to deliver products and provide services to a
larger geographic customer base and that the combination of Deposit Guaranty
and Gonzales Holding can take advantage of increased overall efficiencies and
economies of scale.  See "The Mergers -- Reasons for the Mergers;
Recommendation of the Gonzales Bank Board of Directors.

FAIRNESS OPINION

         The Board of Directors of Gonzales Holding has received the written
opinion of Sheshunoff, Gonzales Holding's financial advisor, that the terms of
the Mergers are fair, from a financial point of view, to Gonzales Holding and
Gonzales Holding shareholders.  The opinion of  Sheshunoff  is attached hereto
as Exhibit B and should be read in its entirety.  See "The Merger -- Opinion of
Financial Advisor."

REGULATORY APPROVALS

         It is a condition to the consummation of the Mergers that all required
regulatory approvals, including the approval of the Office of the Comptroller
of the Currency (OCC) , be obtained.  OCC approval was obtained on April 24 ,
1996.   See "The Mergers -- Regulatory Approvals."

OTHER CONDITIONS TO CONSUMMATION OF THE MERGERS

         In addition to regulatory approvals and the approval by the
shareholders of Gonzales Holding, the respective obligations of each party
under the Merger Agreement are subject, among other conditions, to receipt of
an opinion of Watkins Ludlam & Stennis, P.A. substantially to the effect that
the transactions contemplated by the Merger Agreement will be treated for
federal income tax purposes as a tax-free reorganization under Section 368 of
the Code, and the absence of a material adverse change in the financial
condition, results of operations or business of the other party's consolidated
group.  See "The Merger -- Other Conditions to the Mergers" for a fuller
discussion of the conditions to consummation.

EXCHANGE OF GONZALES HOLDING CERTIFICATES; NO FRACTIONAL SHARES

         As soon as practicable after the Effective Date, The Bank of New York
(the "Exchange Agent") will mail to each holder of record of Gonzales Holding
Common Stock, a letter of transmittal and instructions for use in effecting the
surrender of the certificates which, immediately prior to the Effective Date,
represented outstanding shares of Gonzales Holding Common Stock in exchange for
certificates representing Deposit Guaranty Common Stock.  See "The Merger --
Exchange of Gonzales Holding Certificates."  Cash will be paid in lieu of any
fractional share interests in Deposit Guaranty Common Stock.  See "The Mergers
- -- Structure and Terms of the Mergers."  Certificates representing Gonzales
Holding Common Stock should not be surrendered until the transmittal form is
received.

EFFECTIVE DATE

         If the Merger Agreement is approved by the requisite vote of the
shareholders of Gonzales Holding and the Mergers are approved by all required
regulatory agencies and the other conditions to the Mergers are satisfied or
waived (where permissible), the Merger will become effective at the date (the
"Effective Date") a certificate of merger (the "Certificate of Merger") is
filed with the Secretary of State of Louisiana, or as of such later date in
time to which Deposit Guaranty and Gonzales Holding agree, which may be
specified in the Certificate of Merger to be filed with the Louisiana Secretary
of State pursuant to the Business Corporation Law of the State of Louisiana
(the "Louisiana BCL").  It is expected that the Effective Date will occur in
mid-1996; however, there can be no assurance that the conditions to the Merger
will be satisfied or waived so that the Merger can be consummated.  See "The
Merger -- Effective Date" and "The Mergers -- Other Conditions to the Mergers."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain members of Gonzales Holding's management and Board of
Directors have interests in the Mergers in addition to their interests as
shareholders of Gonzales Holding generally.  Those interests relate to, among
other things, provisions in the Merger Agreement regarding indemnification and
eligibility to participate in certain Deposit Guaranty employee benefit plans.
Executive officers of Gonzales Holding also have an interest in the Mergers as
a result of change





                                       3
<PAGE>   15


in control severance arrangements in their existing employment agreements.  See
"The Mergers - Interests of Certain Persons in the Mergers."

TERMINATION

         Among other reasons, the Merger Agreement may be terminated at any
time prior to the Effective Date (i)  in the event the Merger Agreement is not
approved by the shareholders of Gonzales Holding at the Meeting, (ii) if the
number of shares of Gonzales Holding Common Stock, the holders of which perfect
dissenters' rights, exceeds 10% of the outstanding shares of Gonzales Holding
Common Stock, or (iii) if the Closing has not occurred by December 31, 1996.
The Merger Agreement may also be terminated by mutual consent, or by Gonzales
Holding's Board of Directors if necessary to fulfill its fiduciary duties based
on advice of counsel  upon payment of certain expenses.  See "The Mergers --
Amendment; Waiver; Termination."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         Consummation of the Mergers is conditioned upon receipt of an opinion
of counsel substantially to the effect that the Mergers will be treated, for
federal income tax purposes, as a tax-free reorganization, with the result
that, no gain or loss will be recognized by Gonzales Holding or by holders of
Gonzales Holding Common Stock who exchange all of their Gonzales Holding Common
Stock solely for Deposit Guaranty Common Stock pursuant to the Mergers (except
with respect to cash, if any, received in lieu of fractional shares).  Gonzales
Holding shareholders are urged to consult their own tax advisors as to the
specific tax consequences to them of the Mergers.  See "The Mergers -- Certain
Federal Income Tax Consequences."

ACCOUNTING TREATMENT

         The purchase method of accounting will be used to reflect the Mergers
upon consummation. "The Mergers -- Accounting Treatment."

DISSENTERS' RIGHTS

         Under certain conditions and by complying with the specific procedures
required by Louisiana law and described herein, Gonzales Holding 's
shareholders will have the right to dissent from the Holding Company Merger, in
which event, if the Holding Company Merger is consummated, such shareholders
may be entitled to receive in cash the fair value of their shares of Gonzales
Holding Common Stock.  See "Dissenters Rights" and Exhibit C hereto.

DEPOSIT GUARANTY - RECENT DEVELOPMENTS

         On April 16, 1996, Deposit Guaranty reported that consolidated net
income for the three months ended March 31, 1996, was $21.5 million, or $1.11
per share, compared to $18.0 million, or $.93 per share, for the same period in
1995.  This increase in earnings was primarily due to an increase in net
interest income resulting largely from a 19% increase in loan volume.  The
first quarter of 1996 also included a gain of $1.7 million, after income taxes,
resulting from the disposition of assets related to lease financing
transactions as well as approximately $750 thousand resulting from adoption of
a new accounting pronouncement relating to mortgage service rights.

         Deposit Guaranty's return on average assets for the first quarter of
1996 was 1.44% compared to 1.39% for the same period in 1995.  Return on
average equity for the first quarter of 1996 was 15.97% compared to 15.10% for
the first quarter of 1995.

         Deposit Guaranty's total assets were $6.0 billion at March 31, 1996,
up from $5.4 billion at March 31, 1995.  Stockholder's equity was $520 million
at March 31, 1996, compared to $483 million at March 31, 1995.

Notes Due May 1, 2006 in the aggregate principal amount of $100,000,000.  The
proceeds of the offering will be used for general corporate purposes, including
investments in, and advances to, Deposit Guaranty's banking and nonbanking
subsidiaries, reduction of short-term borrowings, investments, and financing
possible future acquisitions, including, without limitation, the acquisition of
banking and nonbanking companies and financial assets and liabilities.

GENERAL

       This Proxy Statement/Prospectus is being furnished to shareholders of

(the "Meeting") to be held at [2:00 p.m]., local time, on May __, 1996 at the
[Holiday Inn - Gonzales at 1500 West Highway 30, Gonzales, Louisiana], and at
any adjournment or postponement thereof.

       At the Meeting, shareholders will consider and vote upon a proposal to
approve the Merger Agreement, by and among Deposit Guaranty, CNC, Citizens
Bank, Gonzales Holding, and Gonzales Bank pursuant to which Gonzales Holding

shares of Gonzales Holding Common Stock outstanding on the date immediately
preceding the Effective Date.  As a result of the Merger, the shareholders of
Gonzales Holding will become shareholders of Deposit Guaranty.

       This Proxy Statement/Prospectus constitutes a proxy statement of
Gonzales Holding with respect to the Meeting and a prospectus of Deposit
Guaranty with respect to the shares of Deposit Guaranty Common Stock to be
issued in connection with the Mergers.  The information in this Proxy
Statement/Prospectus concerning Deposit Guaranty and its subsidiaries and
Gonzales Holding and its subsidiary has been furnished by each of such
entities, respectively.

       The principal executive office of Deposit Guaranty is located at 210
East Capitol Street, Jackson, Mississippi 39201, and its telephone number is
(601) 354-8497.  The principal executive office of Gonzales Holding is located
at 916 South Burnside Avenue at Worthey Road, Gonzales, Louisiana 70707-1089,
and its telephone number is (504) 542-2265.

       This Proxy Statement/Prospectus is first being mailed to shareholders of
Gonzales Holding on or about May __, 1996.

RECORD DATE; VOTING RIGHTS; PROXIES

       The Board of Directors of Gonzales Holding has fixed the close of
business on ___________________, 1996 as the Record Date for determining
holders of outstanding shares of Gonzales Holding Common Stock entitled to
notice of and to vote at the Meeting.  Only holders of Gonzales Holding Common
Stock of record on the books of Gonzales Holding at the close of business on
the Record Date are entitled to vote at the Meeting or at any adjournment or
postponement thereof.  As of the Record Date, there were 561,801 shares of
Gonzales Holding 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 Gonzales Holding Common Stock is necessary to constitute a
quorum of the stockholders to take action at the Meeting.  Shares of Gonzales
Holding 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
Merger Agreement and, in the discretion of the proxy holders, as to any other
matter which may properly come before the 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 of Gonzales Holding
(i) a notice in writing revoking it, or (ii) a duly executed proxy bearing a
later date or (b) voting in person at the Meeting.

       Approval of the Merger Agreement requires the affirmative vote at the
Meeting of the holders of a majority of the outstanding shares of the Gonzales
Holding Common Stock.  Therefore, an abstention or failure to return a properly
executed proxy will have the same effect as a vote against the Merger
Agreement, as will a broker's submitting a proxy without exercising
discretionary authority with respect to approval of the Merger Agreement.  As
of the Record Date, the executive officers and directors of Gonzales Holding as
a group had the power to vote approximately 119,102 shares of Gonzales Holding
Common Stock, representing approximately 22% of the outstanding shares, all of
which are expected to be voted in favor of the Merger Agreement.

       Deposit Guaranty's shareholders are not required to approve the Merger
Agreement or the issuance of shares of Deposit Guaranty Common Stock.

       Gonzales Holding will bear the costs of soliciting proxies from its
shareholders.  In addition to the use of the mail, proxies may be solicited by
the directors, officers and employees of Gonzales Holding in person, or by
telephone or telegram.  Such directors, officers and employees will not be
additionally compensated for such solicitation but may be reimbursed for
out-of-pocket expenses incurred in connection therewith.  Arrangements will
also be made with custodians, nominees and fiduciaries for the forwarding of
solicitation material to the beneficial owners of Gonzales Holding Common Stock
held of record by such persons, and Gonzales Holding may reimburse such
custodians, nominees and fiduciaries for reasonable out-of-pocket expenses
incurred in connection therewith.


                                  THE MERGERS

GENERAL

       The Merger Agreement provides that, subject to the satisfaction or
waiver (where permissible) of certain conditions, including, among other
things, the receipt of all necessary regulatory approvals, the expiration of
all related waiting periods and the approval by the shareholders of Gonzales
Holding, Gonzales Holding will be merged with and into CNC, and the Gonzales
Bank will be merged with and into Citizens Bank.  As a result of the Mergers,
the separate corporate existence of Gonzales Holding and Gonzales Bank will
cease and the shareholders of Gonzales Holding will become shareholders of
Deposit Guaranty.  The date on which the Mergers will be consummated is herein
referred to as the "Effective Date."  See "The Merger -- Effective Date."

       The description of the Merger Agreement included in this Proxy
Statement/Prospectus is qualified in its entirety by reference to the Merger
Agreement, which is incorporated herein by reference and a copy of which is
attached hereto as Exhibit A.

STRUCTURE AND TERMS OF THE MERGERS

       Upon consummation of the Merger, Gonzales Holding will be merged with
and into CNC and each share of Gonzales Holding Common Stock issued and
outstanding at the Effective Date (other than shares owned by shareholders who,
pursuant to the Louisiana BCL, perfect any right to receive the fair value of
such shares ("Dissenting Shares")) will be converted into and exchangeable for
a number of shares of Deposit Guaranty Common Stock determined by dividing
634,000 by the number of shares of Gonzales Holding Common Stock outstanding on
the date immediately preceding the Effective Date (the "Exchange Ratio").  If
prior to the Effective Date Deposit Guaranty should split or combine Deposit
Guaranty Common Stock, or pay a dividend or other distribution in Deposit
Guaranty Common Stock, then the exchange ratio shall be appropriately adjusted
to reflect such split, combination, dividend or distribution.

       The Exchange Ratio was determined by a process of arm's length
negotiations involving the managements of Gonzales Holding and Deposit Guaranty
and their respective financial advisors.  The 634,000 shares of Deposit
Guaranty Common Stock to be issued upon consummation of the Mergers will
constitute approximately 3.3% of the shares of Deposit Guaranty Common Stock
outstanding immediately after the Effective Date.  This calculation does not
make any adjustment for fractional shares or Dissenting Shares and is based
upon the number of shares of Gonzales Holding Common Stock and Deposit Guaranty
Common Stock outstanding on the Record Date.

       No fractional shares of Deposit Guaranty Common Stock will be issued in
the Mergers.  Any shareholder otherwise entitled to receive a fractional share
of Deposit Guaranty Common Stock will be paid a cash amount in lieu of any such
fractional share determined by multiplying (i) the closing sale price of a
share of Deposit Guaranty Common Stock on the date immediately proceeding the
Effective Date as quoted on the National Association of Securities Dealers
Automated Quotation System, by (ii) the fraction of a share of Deposit Guaranty
Common Stock to which such holder would otherwise be entitled.

BACKGROUND OF MERGERS

       In early 1994 after receiving expressions of interest from several
regional banks to acquire Gonzales Holding, the Gonzales Holding Board engaged
Alex Sheshunoff & Co. Investment Banking ("Sheshunoff") to value Gonzales
Holding and invite acquisition offers.  Of the four preliminary offers
received, in the judgment of the Board, only one represented the appropriate
value of Gonzales Holding and, after a due diligence examination of Gonzales
Holding by the high bidder, that offer was reduced substantially.  The Board
concluded that the offering price was inadequate and the offer was rejected.

       Acquisition offers are often based in part on a multiple of the target's
book value and the adequacy of such offers is often evaluated by this multiple
of book value.  However, if a banking company is excessively capitalized, as
was the case with Gonzales Holding in early 1994, the excess capitalization is
customarily acquired on a dollar for dollar basis rather than as a multiple of
book value.

       In 1994, the Board adopted a dividend policy designed to distribute the
excess capitalization to shareholders through a series of special dividends.
After the payment of these dividends, which reduced the capital of Gonzales
Holding to normal levels, in late 1995 the Board again engaged Sheshunoff to
value Gonzales Holding and seek acquisition offers.  In late 1995, offering
packages were sent to nine large banks resulting in the receipt of nine
non-binding offers.

       During December 1995, the four largest bidders were permitted to perform
due diligence examinations of Gonzales Holding, after which one offer was
withdrawn, one offer was reduced and one offer was increased.  Negotiations
were conducted with the two highest bidders over a period of three weeks,
resulting in the enhancement of both offers.  After considerable examination
and analysis, the Board determined that the offer submitted by Deposit Guaranty
was the highest and best offer and on February 5, 1996 executed the Merger
Agreement with Deposit Guaranty.

       The decision of the Board to enter into the Merger Agreement with
Deposit Guaranty was based on a careful analysis of various factors and after
consulting with the Board's financial, legal and other advisors and Gonzales
Holding management.  Although the two highest offers received were very similar
in terms of exchange ratios, the Board selected Deposit Guaranty because of its
historic and expected stock performance.

REASONS FOR THE MERGERS

       In reaching its decision that the Merger Agreement is in the best
interests of Gonzales Holding and its shareholders, the Board considered a
number of factors in addition to the financial terms, including, but not
limited to the following:

         (a)     the financial condition and results of operations of, and
                 prospects for, each of Gonzales Holding and Deposit Guaranty;

         (b)     the likelihood that Gonzales Bank would experience significant
                 increased competitive pressures in its market area from larger
                 banking and other financial institutions capable of offering a
                 broader array of technologically advanced financial services
                 and products;

         (c)     the lack of marketability of Gonzales Holding Common Stock and
                 the liquidity that would be offered to Gonzales Holding's
                 shareholders through the ownership of securities of a publicly
                 traded company such as Deposit Guaranty;

         (d)     The financial terms of the Mergers, including the relationship
                 of the value of the Deposit Guaranty Common Stock issuable in
                 the Mergers to the market value, book value, and earnings per
                 share of Gonzales Holding Common Stock;





                                       11
<PAGE>   23


         (e)     The nonfinancial terms of the Mergers, including the treatment
                 of the Mergers as a tax-free exchange of Gonzales Holding
                 Common Stock for Deposit Guaranty Common Stock for federal and
                 state income tax purposes;

         (f)     The likelihood of the Mergers being approved by applicable
                 regulatory authorities without undue conditions or delay; and

         (g)     The opinion rendered by Sheshunoff, Gonzales Holding's
                 financial advisor, to the effect that the terms of the
                 Mergers, as provided in the Merger Agreement, are fair from a
                 financial point of view, to the holders of Gonzales Holding
                 Common Stock.

         Gonzales Holding's Board did not assign any specific or relative
weight to the foregoing factors in its considerations.  Gonzales Holding's
Board believes that the Merger Agreement will provide significant value to all
Gonzales Holding shareholders and will enable them to participate in
opportunities for growth that Gonzales Holding's Board believes the Mergers
make possible.

         BASED ON THE FOREGOING, THE BOARD OF DIRECTORS OF GONZALES HOLDING HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT, BELIEVES THAT THE MERGER AGREEMENT
IS IN THE BEST INTERESTS OF GONZALES HOLDING'S SHAREHOLDERS AND RECOMMENDS THAT
ALL SHAREHOLDERS VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT.

         DEPOSIT GUARANTY.  The Deposit Guaranty Board of Directors believes
that by expanding Deposit Guaranty's customer base into the southern portion of
Louisiana, the Mergers should enhance Deposit Guaranty's earnings capacity by
enabling it to deliver products and provide services to that enlarged customer
base, and by permitting cost savings through consolidation of operations.  In
addition, the Deposit Guaranty Board of Directors believes that the combination
of Deposit Guaranty and Gonzales Holding will allow Deposit Guaranty and
Gonzales Holding to increase overall efficiency and take advantage of economies
of scale in several areas.  In evaluating the Mergers, the Deposit Guaranty
Board of Directors considered a variety of factors, including the respective
results of operations, financial condition and prospects of Deposit Guaranty
and Gonzales Holding; the compatibility and complimentary nature of the
respective businesses and managerial philosophies of Deposit Guaranty and
Gonzales Holding; and the relative prices paid in recent acquisitions of
financial institutions.

OPINION OF FINANCIAL ADVISOR

         In October 1995, Gonzales Holding, retained Sheshunoff, an investment
banking firm based in Austin, Texas, on the basis of its experience, to prepare
an information package and contact potential purchasers identified by
Sheshunoff for the purpose of effecting a sale, merger, exchange or other
similar transaction with respect to the shares of Gonzales Holding.
Additionally, Gonzales Holding retained Sheshunoff to render a written fairness
opinion (the "Opinion") to the Board of Directors of Gonzales Holding.
Sheshunoff has been in the business of consulting for the banking industry for
over twenty years, including the appraisal and valuation of banking
institutions and their securities in connection with mergers and acquisitions
and equity offerings.  Sheshunoff has a long history of familiarity and
involvement with the banking industry nationwide, as well as familiarity with
the Louisiana market and recent transactions in this market.  Sheshunoff
reviewed the negotiated terms of the Merger Agreement.  Prior to being retained
for this assignment, Sheshunoff has provided professional services and products
to Gonzales Holding.  The revenues derived from such services and products are
insignificant when compared to Sheshunoff's total gross revenues.

         On January 18, 1996, in connection with its consideration of the Merger
Agreement, Sheshunoff issued its Oral Opinion to the Board of Directors of 
Gonzales Holding that, in its opinion as investment bankers, the terms of the 
Mergers as provided in the Merger Agreement are fair and equitable, from a 
financial perspective, to Gonzales Holding's shareholders.  The Oral Opinion, 
which was confirmed in a written opinion dated May __, 1996, is based upon
conditions as they existed on December 31, 1995.  A copy of the Opinion is
attached as Exhibit B to this Proxy Statement/Prospectus and should be read in
its entirety by Gonzales Holding shareholders.  Sheshunoff's written opinion
does not constitute an endorsement of the Mergers or a recommendation to any
shareholder as to how such shareholder should vote.





                                       12
<PAGE>   24


         In rendering its Opinion, Sheshunoff reviewed certain publicly
available information concerning Gonzales Holding and Deposit Guaranty.
Sheshunoff considered many factors in making its evaluation.  In arriving at
its Opinion regarding the fairness of the transaction, Sheshunoff reviewed: (i)
the Merger Agreement; (ii) the external auditor's reports to the Board of
Directors of Gonzales Holding and the internal audit function of Deposit
Guaranty; (iii) the audited balance sheet and income statement for each of the
past three years for each organization; (iv) each organization's rate
sensitivity analysis reports; (v) each organization's listing of marketable
securities showing rate, maturity and market value as compared to book value;
(vi) each organization's internal loan classification list; (vii) a listing of
other real estate owned for each organization; (viii) the budget and long range
operating plan of each organization; (ix) a listing of unfunded letters of
credit and any other off-balance sheet risks for each organization; (x) the
minutes of the Board of Directors meetings of Gonzales Holding; (xi) the Board
report for each organization; (xii) the listing and description of significant
real properties for each organization; and (xiii) market conditions and current
trading levels of outstanding equity securities of both organizations.
Sheshunoff conducted an on-site review of Gonzales Holding and Deposit
Guaranty.

         In reaching its Opinion, Sheshunoff analyzed the total purchase price
basis using standard evaluation techniques (as discussed below) including
comparable sales multiples (market value), net present value, cash flow
analysis, return on investment and the price as a percentage of total assets
based on certain assumptions of projected growth, earnings and dividends and a
range of discount rates from 12% to 15%.  Sheshunoff also considered as one of
the methods of determining the fairness of the transaction, the projected pro
forma impact on Gonzales Holding shareholders' equivalent earnings per share
and equity per share (appreciation/dilution analysis), which was based upon
stand-alone financial projections for both Gonzales Holding and Deposit
Guaranty compared with pro forma financial projections.

         In performing its analysis, Sheshunoff relied upon financial
projections for Gonzales Holding which were prepared and furnished by the
management of Gonzales Holding.  Deposit Guaranty's projections were prepared
by Sheshunoff based on its review of publicly available information,
discussions with the management of Deposit Guaranty and an on-site due
diligence review of Deposit Guaranty.  Gonzales Holding and Deposit Guaranty do
not publicly disclose internal management projections of the type provided to
Sheshunoff in connection with its review of the Mergers and such projections
were not prepared with a view towards public disclosure.  The projections were
based on numerous variables and assumptions which are inherently uncertain,
including without limitation, factors related to general economic and
competitive conditions.  Accordingly, actual results could vary significantly
from those set forth in such projections.

         In addition, Sheshunoff discussed with the management of Gonzales
Holding and Deposit Guaranty the relative operating performance and future
prospects of each organization, primarily with respect to the current level of
their earnings and future expected operating results, giving weight to
Sheshunoff's assessment of the future of the banking industry and each
organization's performance within the industry.  Sheshunoff compared the
results of operation of Gonzales Holding with the results of operation of a
peer group comprised of all Louisiana banks with total assets of $100 to $499
million (50 banks).  Sheshunoff compared the results of operation of Deposit
Guaranty with the results of operation of a national peer group comprised of
all bank holding companies with total assets between $5 billion and $10 billion
(31 holding companies).

         Many variables affect the value of banks, not the least of which is
the uncertainty of future events, so that the relative importance of the
valuation variables differs in different situations.   The primary financial
variables to be considered are earnings, equity, dividends or dividend-paying
capacity, asset quality and cash flow.  In addition, in most instances, if not
all, value is further tempered by non-financial factors such as marketability,
voting rights or block size, history of past sales of the bank's stock, nature
and relationship of the other shareholders in the bank, and special ownership
or management considerations.

         "Market value" is generally defined as the price, established on an
"arms-length" basis, at which knowledgeable, unrelated buyers and sellers would
agree.  The market value in connection with the evaluation of control of a bank
is determined by the previous sales of banks in the state or region.

         Sheshunoff has access to a substantial database detailing the prices
paid for banking institutions nationwide.  The database includes transactions
involving banking organizations in Louisiana and the surrounding states with
total assets of less than $250 million which sold for 100% stock from March 22,
1995 through March 22, 1996 (the "Market Comparables") and over the past five
years.  The database provides comparable pricing and financial performance data
for banking organizations sold or acquired.  Organized by different peer
groups, the data presents averages of financial performance and





                                       13
<PAGE>   25


purchase price levels, thereby facilitating a valid comparative purchase price
analysis.  In analyzing the transaction value of Gonzales Holding, Sheshunoff
has considered the market approach and has evaluated price to equity and price
to earnings multiples of the Market Comparables.  The following table provides
the 13 banking organizations included in the Market Comparables relative to the
ratios of the transaction as of the date of the fairness opinion:

</TABLE>

         COMPARABLE SALES MULTIPLES.  Sheshunoff calculated a "Purchase price
based on book value" of $49.36 per share based on Gonzales Holding's December
31, 1995 equity and the average price to equity multiple of 2.15x for the
Market Comparables.  Sheshunoff calculated a "Purchase price based on earnings"
of $67.23 per share based on Gonzales Holding's estimated 1996 earnings and the
average price to earnings multiple of 16.24x for the Market Comparables.  The
financial performance characteristics of the banking organizations in the
Market Comparables vary, sometimes substantially, from those of Gonzales
Holding.  When the variance is significant for relevant performance factors,
adjustments to the price multiples are appropriate when comparing them to the
transaction value.

         NET PRESENT VALUE ANALYSIS.  The investment or earnings value of any
banking organization's stock is an estimate of the present value of the future
benefits, usually cash flows with an estimated residual value based on a range
of multiples of earnings or book value at some point in the future.
Sheshunoff's cash flow computations are based on Gonzales Holding's dividend
paying capacity available to common shareholders while maintaining a 6.00% tier
1 leverage ratio and using a net present value discount rate range of 12.00% to
15.00%.  Assuming a residual value based on book value in the year 2005 and a
price to book range of 1.30x to 1.80x resulted in a present value range from
$31.95 per share to $44.83 per share.  Assuming a  residual value based on a
price to earnings range of 10x to 15x resulted in a present value range from
$29.12 per share to $41.26 per share.

         PROJECTED IMPACT ON GONZALES HOLDING SHAREHOLDERS.  Consideration was
given to the levels of book value and earnings per share appreciation or
dilution percentages between the merger partners over the next five years after
consummation.  To justify the fairness of the transaction for Gonzales Holding
shareholders, it is important to project, based upon realistic projections of
future performance, a positive impact for Gonzales Holding shareholders.  It is
important to note that the appreciation/dilution analysis is one of the methods
utilized by Sheshunoff.  The projected appreciation/dilution analysis supports
Sheshunoff's Opinion as to the fairness of the transaction to Gonzales
Holding's shareholders from a financial point of view.  This analysis does not
address future shareholder transactions involving Deposit Guaranty stock after
consummation of the transaction.

         MARKETING EFFORTS.  In rendering its opinion Sheshunoff considered the
marketing efforts Gonzales Holding undertook prior to signing the Merger
Agreement with Deposit Guaranty.  In connection with the sale, the management
of Gonzales Holding believed the value of Gonzales Holding would be maximized
by soliciting offers from prospective buyers.





                                       14
<PAGE>   26


A marketing effort was undertaken by Sheshunoff, which produced indications of
interest from nine regional holding companies.  The highest four bidders where
invited to perform due diligence at Gonzales Holding.  After a final round of
offers were analyzed, Gonzales Holding entered into discussions with Deposit
Guaranty which led to the Merger Agreement.

         There are many other factors to consider, when valuing a going
concern, which do not directly impact the earnings stream and the net present
value but which do exert a degree of influence over the fair market value of a
going concern.  These factors include, but are not limited to, the general
condition of the industry, the economic and competitive situations in the
market area and the expertise of the management of the organization being
valued.

         Neither Gonzales Holding nor Deposit Guaranty imposed any limitations
upon the scope of the investigation to be performed by Sheshunoff in
formulating such Opinion.  In rendering its Opinion, Sheshunoff did not
independently verify the asset quality and financial condition of Gonzales
Holding or Deposit Guaranty, but instead relied upon the data provided by or on
behalf of Gonzales Holding and Deposit Guaranty to be true and accurate in all
material respects.

         For its services as independent financial analyst for the transaction,
including the rendering of its Opinion referred to above, Gonzales Holding has
agreed to pay Sheshunoff aggregate fees of 0.75% of the total consideration
paid, which includes the professional fee for the Opinion.

EFFECTIVE DATE

         The Mergers will be consummated and become effective at the time a
certificate of merger (the "Certificate of Merger") is filed with the Secretary
of State of Louisiana, or as of such later date or time to which Deposit
Guaranty and Gonzales Holding agree, which may be specified in the Certificate
of Merger.  Unless Deposit Guaranty and Gonzales Holding otherwise agree, the
Mergers will be consummated as soon as practicable following receipt of
Gonzales Holding shareholder and necessary regulatory approvals and
satisfaction or waiver of the other conditions to the Mergers.  It is expected
that the Effective Date will occur in mid-1996; however, there can be no
assurance that the conditions to the Merger will be satisfied or waived so that
the Merger can be consummated.  See "The Merger -- Regulatory Approvals" and --
"Other Conditions to the Mergers."

REGULATORY APPROVALS

         Consummation of the Mergers is conditioned on approval by all required
regulatory authorities, including approval by the OCC.  OCC approval was
obtained on April 24, 1996. The Board of Governors of the Federal Reserve
System, the Louisiana Office of Financial Institutions and the Federal Deposit
Insurance Corporation must also review the Bank Merger and comment on the
competitive factors involved.  The Bank Merger may not be consummated until the
expiration of fifteen (15) days after approval by the OCC has been obtained.
During this 15-day period, the United States Department of Justice, if it
objects to the proposed Bank Merger for antitrust reasons, may file suit to
enjoin the Bank Merger.

OTHER CONDITIONS TO THE MERGERS

         In addition to Gonzales Holding shareholder and regulatory approval,
the respective obligations of each party under the Merger Agreement are
subject, among other conditions, to (i) the absence of any order, decree or
injunction of a court or agency of competent jurisdiction enjoining or
prohibiting consummation of the Mergers, (ii) receipt of an opinion of  Watkins
Ludlam & Stennis, P.A. substantially to the effect that the transactions
contemplated by the Merger Agreement will be treated for federal income tax
purposes as a tax-free reorganization under Section 368 of the Code, (iii) that
on the date of closing the representations and warranties made in the Merger
Agreement by each party are true and correct in all material respects, (iv)
that prior to the Effective Date there not have been a material adverse change
in the financial condition, results of operations or business of the other
party's consolidated group and (v) the receipt of customary legal opinions.

INTERESTS OF CERTAIN PERSONS IN THE MERGERS

         INDEMNIFICATION.  The Merger Agreement provides that CNC shall
indemnify the former directors, officers, employees and agents of Gonzales
Holding against all claims to which they become subject arising out of actions
or omissions occurring at or prior to the Effective Date of the Mergers,
including the transactions contemplated by the Merger





                                       15
<PAGE>   27


Agreement, to the full extent permitted by Louisiana law or by Gonzales Holding
's Articles of Incorporation and Bylaws.  The Merger Agreement also provides
that Citizens Bank  shall indemnify the former directors, officers, employees
and agents of Gonzales Bank against all claims to which they become subject
arising out of actions or omissions occurring at or prior to the Effective Date
of the Mergers, including the transactions contemplated by the Merger
Agreement, to the full extent permitted by Louisiana law or by Gonzales Bank 's
Articles of Incorporation and Bylaws.  CNC and Citizens Bank have agreed to use
their best efforts to maintain Gonzales Holding 's and Gonzales Bank's existing
directors' and officers' liability insurance policies (or a policy providing at
least comparable coverage) for a period of five (5) years after the Effective
Date of the Mergers.  The Merger Agreement also provides for indemnification by
Deposit Guaranty of Gonzales Holding and its officers, directors and control
persons from and against liability arising under the Securities Act or
otherwise if such liability arises out of or is based on an untrue statement or
omission of a material fact required to be stated in the Registration
Statement, of which this Proxy Statement/Prospectus forms a part, or in any
amendment or supplement thereto, or necessary to make the statements made not
misleading.  This indemnification does not apply to statements made in reliance
on information furnished to Deposit Guaranty by or on behalf of Gonzales
Holding or Gonzales Bank for use in the Registration Statement.

         EMPLOYEE BENEFITS.  The Merger Agreement provides that, after the
Effective Date of the Mergers, Deposit Guaranty will, subject to compliance
with applicable legal and regulatory requirements, provide coverage for all
employees of Gonzales Holding and Bank of Gonzales under Deposit Guaranty's
benefit plans for which they are eligible, as soon as practicable after the
Effective Date.  All prior years of service of Gonzales Bank employees will be
counted for vesting and eligibility purposes under all applicable Deposit
Guaranty employee benefit plans to the extent permitted by applicable law.  Any
Gonzales Bank employee who, immediately prior to the Effective Date, is covered
by or is a participant in a Gonzales Bank employee benefit plan, shall, on the
Effective Date, be covered by or participate in the comparable Deposit Guaranty
employee benefit plan if a comparable plan otherwise is maintained by Deposit
Guaranty and if the eligibility requirements of the Deposit Guaranty plan are
met.

         EMPLOYMENT AND SEVERANCE ARRANGEMENTS.  Gonzales Holding is a party to
an Amended and Restated Employment Agreement (the "Employment Agreement") with
its Chief Executive Officer, Mr. Dale Gaudet, which terminates on December 31,
1998.  In accordance with this agreement, if the Gonzales Bank terminates the
Mr. Gaudet's employment without cause, then Gonzales Holding shall pay him his
full salary through the date of termination, and in lieu of any further salary
payments to him for periods subsequent to the date of termination, shall pay as
severance an amount equal to the present value (using a discount rate of 5%) of
the remaining salary due to him under the agreement.

         Gonzales Holding is also a party to Amended and Restated Contingency
Severance Agreements ("Severance Agreements") with each of three (3) senior
vice-presidents, namely Rachel P. Cherco, James H. May, Jr. and Ida N. Reine,
the latest of which terminates on December 31, 1998.  Under the Severance
Agreements, if the executive officer's employment with Gonzales Holding or
Gonzales Bank of Gonzales is terminated without "Cause" (as defined in the
Employment Agreement) within two years after a "Change in Control," then the
executive officer will be entitled to receive certain severance payments and
benefits.  For purposes of the agreements, "Cause" generally will exist only if
the executive officer dies or is disabled for a continuous period of 180 days,
if he or she commits or is charged with a felony or any crime involving moral
turpitude, the willful and continuing failure by the executive officer to
promptly and efficiently discharge and perform those duties assigned to the
executive him or her in a manner in which such duties were performed prior to
the "Change in Control," or certain other criminal or unethical activities.

         The Mergers will constitute a "Change in Control" for purposes of the
Severance Agreements.  If an executive officer who is a party to a Severance
Agreement is discharged within two years after the Mergers without "Cause," he
or she will be entitled to receive, in addition and without prejudice to any
other rights he or she may have, including the right to bring a claim for
damages, an amount equal to the excess, if any, of (i) two times his or her
salary over (ii) the amount of compensation paid to the executive officer after
the Change in Control.

         Deposit Guaranty has agreed in the Merger Agreement to assume Gonzales
Holding 's obligations under these Employment and Severance Agreements.

<PAGE>   28


         ELECTION TO CITIZENS BANK BOARD.  The Merger Agreement provides that
for a period of not less than three years after the Mergers are consummated, at
least two former directors of Gonzales Bank will be elected to serve as
directors of Citizens Bank.

EXCHANGE OF GONZALES HOLDING CERTIFICATES

         At the Effective Date, each Gonzales Holding shareholder will cease to
have any rights as a shareholder of Gonzales Holding and his or her sole rights
will pertain to the shares of Deposit Guaranty Common Stock to which such
holder's shares of Gonzales Holding Common Stock shall have been converted
pursuant to the Mergers, except for the right to receive cash for any
fractional shares.

         As soon as practicable following the Effective Date, the Exchange
Agent for the Deposit Guaranty Common Stock will mail to each holder of record
of Gonzales Holding Common Stock a letter of transmittal and instructions for
effecting the surrender of the stock certificates which, immediately prior to
the Effective Date, represented outstanding shares of Gonzales Holding Common
Stock in exchange for certificates representing shares of Deposit Guaranty
Common Stock.  SHAREHOLDERS OF GONZALES HOLDING ARE REQUESTED NOT TO SURRENDER
THEIR GONZALES HOLDING CERTIFICATES FOR EXCHANGE UNTIL SUCH LETTER OF
TRANSMITTAL AND INSTRUCTIONS ARE RECEIVED.  Upon surrender of a certificate
representing Gonzales Holding Common Stock for exchange and cancellation to the
Exchange Agent, together with a duly executed letter of transmittal, the holder
of such Gonzales Holding Common Stock shall be entitled to receive in exchange
therefor a Deposit Guaranty certificate representing the number of whole shares
of Deposit Guaranty Common Stock to which such holder of Gonzales Holding
Common Stock shall have become entitled pursuant to the Merger Agreement, and a
check in payment for any fractional share of Deposit Guaranty Common Stock to
which such holder may be entitled.

         After the Effective Date and until surrendered, certificates
representing Gonzales Holding Common Stock will be deemed for all purposes,
other than the payment of dividends or other distributions, if any, in respect
of Deposit Guaranty Common Stock, to represent the number of whole shares of
Deposit Guaranty Common Stock into which such shares of Gonzales Holding Common
Stock have been converted. Deposit Guaranty will not pay former shareholders of
Gonzales Holding who become holders of Deposit Guaranty Common Stock pursuant
to the Mergers any dividends or other distributions that may have become
payable to holders of record of Deposit Guaranty Common Stock following the
Effective Date until they have surrendered their certificates evidencing
ownership of shares of Gonzales Holding Common Stock along with a properly
completed letter of transmittal.

         Gonzales Holding shareholders who cannot locate their certificates are
urged to contact promptly the Secretary of Gonzales Holding at South Burnside
Avenue at Worthey Road, Post Office Box 1089, Gonzales, Louisiana 70707,
telephone number (504) 621-7200. A new certificate will be issued to replace
the lost certificate(s) only upon execution by the shareholder of an affidavit
certifying that his or her certificate(s) cannot be located and an agreement to
indemnify Gonzales Holding and Deposit Guaranty and their transfer agents and
registrars against any claim that may be made against Gonzales Holding or
Deposit Guaranty by the owner of the certificate(s) alleged to have been lost
or destroyed.  Gonzales Holding or Deposit Guaranty may also require the
shareholder to post a bond in such sum as is sufficient to support the
shareholders' agreement to indemnify Gonzales Holding and Deposit Guaranty.

AMENDMENT; WAIVER; TERMINATION

         The Merger Agreement may be amended at any time before or after its
approval by the shareholders of Gonzales Holding by written agreement of
Gonzales Holding and Deposit Guaranty, except that no amendment may be made
after Gonzales Holding shareholder approval that by law would require further
shareholder approval unless such further shareholder approval is obtained.

         The Merger Agreement provides that either party may (i) extend the
time for performance of any of the obligations or other acts of the other
parties, (ii) waive any inaccuracies in the representations and warranties
contained in the Merger Agreement or in any document delivered pursuant to the
Merger Agreement or (iii) waive compliance with any of the agreements or
conditions contained in the Merger Agreement other than the satisfaction of all
requirements prescribed by law for consummation of the Mergers.





                                       17
<PAGE>   29


         The Merger Agreement may be terminated at any time prior to the
Effective Date (a) by mutual written consent of the parties, properly
authorized by their respective Boards of Directors; (b) by Deposit Guaranty,
CNC, and Citizens Bank, (i) if at the time of such termination there shall be a
material adverse change in the consolidated financial condition of Gonzales
Bank or Gonzales Holding from that set forth in Gonzales Bank's or Gonzales
Holding's financial statements for the period ended December 31, 1995; (ii) in
the event there are dissenting shareholders who hold more than ten percent
(10%) of the shares of Gonzales Holding Common Stock, or (iii) if the
transaction is not consummated by December 31, 1996; (c)  by any party, if (i)
a United States District Court shall rule upon application of the Department of
Justice after a full trial on the merits or a decision on the merits based on a
stipulation of facts that the transactions contemplated by this Agreement
violate the antitrust laws of the United States; or (ii) the Merger Agreement
shall not have been approved by the affirmative vote of the holders of at least
a majority of the outstanding shares of Gonzales Holding Common Stock; or (d)
by Gonzales Holding's Board of Directors if necessary to fulfill its fiduciary
duties based on advice of counsel  upon payment of certain expenses.

CONDUCT OF BUSINESS PENDING THE MERGERS

         The Merger Agreement provides that Gonzales Bank and Gonzales Holding
will conduct their businesses and engage in transactions only in the ordinary
course and consistent with prudent banking practice.  Without the prior consent
of Deposit Guaranty, neither Gonzales Bank nor Gonzales Holding shall (i)
increase by more than ten percent (10%) the compensation payable by Gonzales
Bank or Gonzales Holding to any of its directors, officers, agents,
consultants, or any of its employees whose total compensation after such
increase would be in excess of $25,000 per annum, grant or pay any
extraordinary bonus, percentage compensation, service award or other like
benefit to any such director, officer, agent, consultant or employee, or make
or agree to any extraordinary welfare, pension, retirement or similar payment
or arrangement for the benefit of any such director, officer, agent, consultant
or employee, (ii) sell or dispose of material assets except in the ordinary
course of business, (iii) enter into any new capital commitments or make any
capital expenditures, except commitments or expenditures within existing
operating and capital budgets or otherwise in the ordinary course of business,
or (iv) authorize or issue any additional shares of any class of its capital
stock or any securities exchangeable for or convertible into any such shares or
any options or rights to acquire any such shares, or otherwise authorize or
affect any change in its capitalization.  In addition, no dividends shall be
paid by Gonzales Holding, except for (i) a special dividend by Gonzales Holding
in February, 1996 of $2.00 per share, and (ii) regular quarterly dividends in
1996 of $.35 per share for each complete calendar quarters that elapses prior
to the Effective Date, and no dividends shall be paid by Gonzales Bank except
dividends by Gonzales Bank to Gonzales Holding to the extent necessary to fund
authorized dividends of Gonzales Holding and to pay necessary and routine
expenses of Gonzales Holding.

         In addition, Gonzales Holding has agreed that, without the prior
approval of Deposit Guaranty, it will not solicit or encourage inquiries or
proposals with respect to, or, except to the extent required in the opinion of
its counsel to discharge properly its fiduciary duties to Gonzales Holding's
consolidated group and its shareholders, furnish any information relating to or
participate in any negotiations or discussion concerning, any acquisition or
purchase of all or a substantial portion of the assets of, or a substantial
equity interest in, or any business combination with, Gonzales Holding or
Gonzales Bank, other than as contemplated by the Merger Agreement.  Gonzales
Holding has also agreed to instruct its officers, directors, agents and
affiliates to refrain from doing any of the above and to notify Deposit
Guaranty immediately if any such inquiries or proposals are received by, any
such information is requested from, or any negotiations or discussions are
sought to be initiated with it or any of its officers, directors, agents and
affiliates.

RESALES OF DEPOSIT GUARANTY COMMON STOCK

         The shares of Deposit Guaranty Common Stock to be issued to the
holders of Gonzales Holding Common Stock pursuant to the Merger Agreement are
being registered under the Securities Act pursuant to a Registration Statement
on Form S-4, of which this Proxy Statement/Prospectus is a part, thereby
allowing such shares to be freely transferred without restriction by persons
who will not be "affiliates" of Deposit Guaranty or who were not "affiliates"
of Gonzales Holding within the meaning of Rule 145 under the Securities Act. In
general, affiliates of Gonzales Holding include its executive officers and
directors and any person who controls, is controlled by or is under common
control with Gonzales Holding. Holders of Gonzales Holding Common Stock who are
affiliates of Gonzales Holding will not be able to resell the Deposit Guaranty
Common Stock received by them in the Mergers unless the Deposit Guaranty Common
Stock is registered for





                                       18
<PAGE>   30


resale under the Securities Act, is sold in compliance with Rule 145 under the
Securities Act or is sold in compliance with another exemption from the
registration requirements of the Securities Act.

         Pursuant to Rule 145 under the Securities Act, the sale of Deposit
Guaranty Common Stock held by former affiliates of Gonzales Holding will be
subject to certain restrictions. Such persons may sell Deposit Guaranty Common
Stock under Rule 145 only if (i) Deposit Guaranty has filed all reports
required to be filed by it under Section 13 or 15(d) of the Exchange Act during
the preceding twelve months, (ii) such Deposit Guaranty Common Stock is sold in
a "broker's transaction," which is defined in Rule 144 under the Securities Act
as a sale in which (a) the seller does not solicit or arrange for orders to buy
the securities, (b) the seller does not make any payment other than to the
broker, (c) the broker does no more than execute the order and receive a normal
commission and (d) the broker does not solicit customer orders to buy the
securities, and (iii) such sale and all other sales made by such person within
the preceding three months do not exceed the greater of (x) one percent of the
outstanding shares of Deposit Guaranty Common Stock or (y) the average weekly
trading volume of Deposit Guaranty Common Stock on the Nasdaq National Market
during the four-week period preceding the sale. Any affiliate of Gonzales
Holding who is not an affiliate of Deposit Guaranty after the Mergers may sell
Deposit Guaranty Common Stock without restriction following the second
anniversary of the Effective Date.

         Gonzales Holding has agreed to use its best efforts to cause each of
its directors and executive officers and each person who is a beneficial owner
of 5% or more of the outstanding Gonzales Holding Common Stock (each of whom
may be deemed to be an affiliate under the Securities Act) to enter into an
agreement not to sell shares of Deposit Guaranty Common Stock received by him
or her in violation of the Securities Act or the rules and regulations of the
Commission thereunder.

EXPENSES AND FEES

         All legal and other costs and expenses incurred in connection with the
Mergers and the transactions contemplated thereby will be paid by the party
incurring such costs and expenses, except that if the Merger Agreement is
terminated by Gonzales Holding's Board of Directors to fulfill its fiduciary
duties based on advice of counsel, Gonzales Holding will be required to
indemnify Deposit Guaranty for all expenses incurred by it in connection with
the Mergers.

ACCOUNTING TREATMENT

         The Mergers, if consummated as proposed, will be treated as a purchase
for accounting and financial reporting purposes.  The purchase method accounts
for a business combination as the acquisition of one enterprise by another, the
value of the company's shares issued in the transaction is included in
stockholders' equity and any of such amount in excess of net fair values of
tangible and identifiable intangible assets of the acquired company is treated
as an intangible asset on the acquiring company's financial statements.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following discussion of the principal federal income tax
consequences of the Mergers is based on provisions of the Internal Revenue Code
of 1986 (the "Code"), the regulations thereunder, judicial authority, and
administrative rulings and practice as of the date hereof or before the
Effective Date.  Consummation of the Mergers is conditioned on the receipt by
Deposit Guaranty and Gonzales Holding of an opinion of counsel to Deposit
Guaranty to the effect that the Merger will be treated, for federal income tax
purposes, as a tax-free reorganization under Section 368(a) of the Code.

         Any Gonzales Holding shareholder who, pursuant to the Mergers,
exchanges all of the Gonzales Holding Common Stock that such holder owns solely
for Deposit Guaranty Common Stock will not recognize any gain or loss upon such
exchange.  The aggregate tax basis of Deposit Guaranty Common Stock received by
such a holder in exchange for Gonzales Holding Common Stock will equal such
holder's tax basis in the Gonzales Holding Common Stock surrendered.  If such
shares of Gonzales Holding Common Stock are held as capital assets at the
Effective Date, the holding period of the Deposit Guaranty Common Stock
received will include the holding period of the Gonzales Holding Common Stock
surrendered therefor.  Gonzales Holding shareholders should consult their tax
advisors as to the determination of their tax basis and holding period in any
one share of Deposit Guaranty Common Stock, as several methods of determination
may be available.





                                       19
<PAGE>   31



         To avoid the expense and inconvenience to Deposit Guaranty of issuing
fractional shares, no fractional shares of Deposit Guaranty Common Stock will
be issued pursuant to the Mergers.  Any Gonzales Holding shareholder who
receives cash pursuant to the Mergers in lieu of a fractional share interest
will be treated as having received such fractional share pursuant to the
Mergers, and then as having exchanged such fractional share for cash in a
redemption by Deposit Guaranty subject to Section 302(a) of the Code, provided
that such deemed redemption is not "substantially disproportionate" with
respect to such Gonzales Holding shareholder or is "not essentially equivalent
to a dividend." If the Deposit Guaranty Common Stock represents a capital asset
in the hands of the shareholder, then the shareholder will generally recognize
capital gain or loss on such a deemed redemption of the fractional share in an
amount determined by the difference between the amount of cash received for
such fractional share and the shareholder's tax basis in the fractional share.

         Gonzales Holding shareholders who perfect dissenters' rights will be
treated as having received the fair value of the Gonzales Holding Common Stock,
as determined in the dissenters' rights proceeding, in redemption of the
Gonzales Holding Common Stock subject to the proceeding.  Such deemed
redemption will be subject to Section 302(a) of the Code, if such deemed
redemption is "substantially disproportionate" with respect to the Gonzales
Holding shareholder who exercises dissenters' rights or is "not essentially
equivalent to a dividend," with the result that a holder who exercises
dissenters' rights will recognize gain or loss equal to the difference between
the amount realized and such holder's tax basis in the Gonzales Holding Common
Stock subject to the proceeding.  Any such gain or loss recognized on such
redemption will be treated as capital gain or loss if the Gonzales Holding
Common Stock with respect to which dissenters' rights were exercised were held
as capital assets.  Each Gonzales Holding shareholder who contemplates
exercising dissenters' rights should consult a tax advisor as to the
possibility that all or a portion of the payment received pursuant to the
dissenters' proceeding will be treated as dividend income.

         Unless an exemption applies under the applicable law and regulations,
the Exchange Agent will be required to withhold thirty-one percent (31%) of any
cash payments to which a shareholder or other payee is entitled pursuant to the
Mergers unless the shareholder or other payee provides its taxpayer
identification number (social security number or employer identification
number) and certifies that such number is correct.  Each shareholder and, if
applicable, each other payee should complete and sign the substitute Form W-9
included as part of the transmittal letter so as to provide the information and
certification necessary to avoid backup withholding, unless an applicable
exemption exists and is established in a manner satisfactory to Deposit
Guaranty and the Exchange Agent.

         THE FOREGOING CONSTITUTES ONLY A GENERAL DESCRIPTION OF CERTAIN
FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS WITHOUT REGARD TO THE PARTICULAR
FACTS AND CIRCUMSTANCES OF EACH GONZALES HOLDING SHAREHOLDER.  GONZALES HOLDING
SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX
CONSEQUENCES TO THEM OF THE MERGERS, INCLUDING THE APPLICABILITY AND EFFECT OF
FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.


                               DISSENTERS' RIGHTS

         Under Section 131 of the Louisiana BCL (a copy of which is attached
hereto as Exhibit C), any holder of record of shares of Gonzales Holding Common
Stock, who files a written objection to the Mergers prior to or at the Meeting
at which the vote on the Mergers is taken, and who votes against the Mergers,
may demand in writing that such shareholder be paid in cash the fair cash value
of such shares ("Dissenters' Rights").  HOWEVER, INTERESTED PARTIES SHOULD NOTE
THAT, IF THE MERGER AGREEMENT IS APPROVED BY EIGHTY PERCENT (80%) OR MORE OF
THE OUTSTANDING SHARES OF GONZALES HOLDING COMMON STOCK, SECTION 131 OF THE
LOUISIANA BCL PROVIDES THAT NO GONZALES HOLDING SHAREHOLDER WILL HAVE
DISSENTERS' RIGHTS.  A person who is a beneficial owner, but not a registered
owner, of shares of Gonzales Holding Common Stock who wishes to exercise the
rights of a dissenting shareholder under the Louisiana BCL cannot do so in his
own name but 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 Exhibit C 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 MERGERS

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

NOTICE OF THE EFFECTIVE DATE

         If the Merger Agreement is approved by less than eighty percent (80%)
of the outstanding shares of Gonzales Holding Common Stock, then, promptly
after the Effective Date, notice will be given to each Dissenter that the
Mergers have become effective.  The notice shall be sent by registered mail,
addressed to the Dissenter at such Dissenter's last address on Gonzales
Holding'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 CNC 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 Meeting,
stating the amount demanded and a post office address to which CNC may reply.
Simultaneously with the filing of the Demand, the Dissenter shall also deposit
the certificate(s) representing his shares of Gonzales Holding Common Stock
(duly endorsed and transferred to CNC upon the sole condition that the
certificate(s) will be delivered to CNC 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 Ascension Parish, Louisiana (the "Escrow
Bank").  Along with the Demand, the Dissenter shall deliver to CNC a written
acknowledgment of the Escrow Bank that it holds such certificate(s), endorsed
as specified above.

         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 Mergers and will forfeit any right to seek payment pursuant to Section
131.  Such written demand may be sent to CNC.

APPRAISAL

         If CNC 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 CNC's assertion that no payment is due, he must within sixty
(60) days after the receipt of such notice file suit against CNC in Ascension
Parish, Louisiana for a judicial determination of the fair cash value of his
shares.  Any Dissenter who is also entitled to file such suit may, within such
60-day period but not thereafter, intervene as a plaintiff in any suit filed
against CNC by another former shareholder of Gonzales Holding 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 CNC's statement that no payment is due or, if CNC does not contend that
no payment is due, to accept the value of his shares specified by CNC in its
notice of disagreement.

         Dissenters 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





                                       21
<PAGE>   33


would otherwise receive pursuant to the Merger Agreement 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 Merger Agreement at any time before CNC
gives its notice of disagreement, but thereafter the Dissenter may withdraw his
or her Demand only with the consent of CNC.  If a Demand is properly withdrawn,
or the Dissenter otherwise loses his Dissenters' Rights, a Dissenter shall only
be entitled to receive the consideration offered pursuant to the Merger
Agreement.

         When the fair cash value of the Dissenter's Shares is agreed upon
between the Dissenter and CNC, or CNC has become liable for the value demanded
by the Dissenter because of its failure to give Notice of Disagreement, or the
Dissenter has become bound to accept the value which CNC agrees is due because
of his failure to bring suit within sixty (60) days after receipt of the Notice
of Disagreement, CNC may, at its option, pay to the Escrow Bank the amount
which the Dissenter is entitled to receive for his shares, and CNC shall be
entitled to receive such shares from the Escrow Bank.  Any action by the
Dissenter to recover such value must be brought within five (5) years from the
date the value was agreed upon, or the liability of CNC became fixed.

PAYMENT AND COSTS

         If upon the filing of any such suit or intervention CNC deposits with
the court the amount, if any, which it specified in its Notice of Disagreement,
and if in that notice CNC 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 fees) will be assessed
against CNC.

NOTICES

         Prior to the Effective Date, dissenting shareholders of Gonzales
Holding should send any communications regarding their rights to Ida N. Reine,
Secretary, Bank of Gonzales Holding Company, Inc., South Burnside Avenue at
Worthey Road, Post Office Box 1089, Gonzales, Louisiana 70707. On or after the
Effective Date, dissenting shareholders should send any communications
regarding their rights to J. Clifford Harrison, Secretary, Commercial National
Corporation, Post Office Box 1200, Jackson, Mississippi 39215-1200.  All such
communications should be signed by or on behalf of the dissenting shareholder
in the form in which his shares are registered on the books of Gonzales
Holding.  Deposit Guaranty, CNC and Citizens Bank have the right to terminate
the Merger Agreement if the number of shares of Gonzales Holding Common Stock
as to which holders thereof are legally entitled to assert dissenters' rights
exceeds 10% of the outstanding shares of Gonzales Holding Common Stock. See
"The Mergers - Amendment; Waiver; Termination."

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


                       COMPARATIVE RIGHTS OF SHAREHOLDERS

         Gonzales Holding is incorporated in the State of Louisiana and Deposit
Guaranty is incorporated in the State of Mississippi.  If the Mergers are
consummated, shareholders of Gonzales Holding, whose rights as shareholders are
currently governed by Louisiana law and by Gonzales Holding's Amended and
Restated Articles of Incorporation (the "Gonzales Holding Articles") and
Bylaws, will, upon consummation of the Mergers, become shareholders of Deposit
Guaranty and their rights as such will be governed by Mississippi law and by
Deposit Guaranty's Articles of Incorporation (the "Deposit Guaranty Articles")
and Bylaws.





                                       22
<PAGE>   34


         Certain significant differences between the rights of shareholders of
Gonzales Holding and shareholders of Deposit Guaranty are set forth below.
This summary is not intended to be relied upon as an exhaustive list or a
detailed description of the provisions discussed and is qualified in its
entirety by the Louisiana BCL and the Mississippi Business Corporation Act (the
"Mississippi BCA") and by the Articles of Incorporation and Bylaws of each of
Gonzales Holding and Deposit Guaranty, respectively, to which Gonzales Holding
shareholders are referred.

CUMULATIVE VOTING RIGHTS

         GONZALES .  Each outstanding share of Gonzales Holding stock is
entitled to one (1) vote on each matter submitted to a vote.  The Gonzales
Holding Articles do not provide for cumulative voting in the election of
directors.

         DEPOSIT GUARANTY.  Pursuant to the Mississippi BCA and Deposit
Guaranty's Bylaws, each outstanding share of Deposit Guaranty stock is entitled
to one (1) vote on each matter submitted to a vote.  However, in connection
with the election of directors, holders of Deposit Guaranty Common Stock have
cumulative voting rights.  Pursuant to the Deposit Guaranty Bylaws, every
shareholder entitled to vote in the election of directors shall have the right
to vote, in person or by proxy, the number of shares owned by him for as many
persons as there are directors to be elected, or to cumulate his votes by
giving one (1) candidate the number of votes equal to the number of directors
to be elected multiplied by the number of his shares, or by distributing such
votes on the same principle among any number of candidates.

LIMITATIONS ON DIRECTORS' AND OFFICERS' LIABILITY

         GONZALES HOLDING.  Gonzales Holding's Articles provide that no
director or officer of Gonzales Holding shall be liable to Gonzales Holding or
its shareholders for monetary damages for breach of fiduciary duty as a
director or officer, provided that the foregoing provision shall not eliminate
or limit the liability of a director or officer for (a) any breach of his duty
of loyalty to the Corporation or its shareholders; (b) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law; (c) unlawful payment of dividends, distribution of assets, or purchase or
redemption of Gonzales Holding shares, or  (d) any transaction from which he
derived an improper personal benefit.

         DEPOSIT GUARANTY.  Deposit Guaranty's Articles and Bylaws do not
contain any provision limiting the personal liability of Deposit Guaranty's
directors and officers for monetary damages resulting from breach of fiduciary
duty.

SUPERMAJORITY VOTING REQUIREMENTS; BUSINESS COMBINATIONS; CONTROL SHARES

         GONZALES HOLDING.  The Gonzales Holding Articles provide that, except
as is otherwise made mandatory by law, an agreement of merger or consolidation
of Gonzales Holding, the sale of all or substantially all of the assets of
Gonzales Holding, or the dissolution of Gonzales Holding may be authorized by
the affirmative vote of two-thirds of the total voting power of Gonzales
Holding, unless the transaction is approved by two-thirds of the Board of
Directors in which case, only a majority of the total voting power is required
to approve the transaction.

         Gonzales Holding is subject to Louisiana's Fair Price Protection
Statute (Sections 132-134 of the Louisiana BCL), which requires that, in
addition to any vote otherwise required by law or a corporation's articles of
incorporation, any "business combination" (as defined in the statute) between a
corporation and the holder of 10% or more of its total voting power be
recommended by the corporation' s board of directors and approved by (i) at
least 80% of the total voting power of the corporation and (ii) at least
two-thirds of the votes entitled to be cast by shareholders other than the 10%
shareholder, unless certain minimum price, form of consideration and procedural
requirements are satisfied by the 10% shareholder, or if the board approves the
business combination before the 10% shareholder becomes a 10% shareholder.  The
Fair Price Protection Statute does not apply to the Mergers.

         DEPOSIT GUARANTY.  Deposit Guaranty's Articles require that any
Business Combination (as defined below) involving Deposit Guaranty or a
subsidiary of Deposit Guaranty and an Interested Shareholder (as defined below)
or any affiliate or associate of an Interested Shareholder or any person that
following such transaction would be an affiliate or associate of an Interested
Shareholder be approved by the affirmative vote of at least eighty percent
(80%) of the votes entitled to be cast by the holders of all the then
outstanding shares of voting stock of Deposit Guaranty, excluding shares





                                       23
<PAGE>   35


held by the Interested Shareholder, unless the transaction is approved by a
majority of the Continuing Directors (as defined below) or unless certain fair
price and procedural requirements are satisfied.

REMOVAL OF DIRECTORS

         GONZALES HOLDING.  Gonzales Holding's Articles provide that Gonzales
Holding shareholders may remove a director upon the affirmative vote of
shareholders holding 75% of the total voting power at any special meeting
called for that purpose, even though the director's term has not expired.

         DEPOSIT GUARANTY.  Deposit Guaranty's Articles provide that Deposit
Guaranty shareholders may remove a director with or without cause, but only at
a meeting expressly called for that purpose and upon the affirmative vote of
the holders of at least eighty percent (80%) of the voting power of all shares
of stock entitled to vote generally in the election of directors, and in the
event that less than the entire Board is to be removed, not one of the
directors may be removed if the votes cast against his removal would be
sufficient to elect him if then cumulatively voted at an election of the class
of directors of which he is a part.

VACANCIES IN THE BOARD OF DIRECTORS

         GONZALES HOLDING.  Under Gonzales Holding's Bylaws, any vacancy
occurring in the Gonzales Holding Board of Directors (including any vacancy
resulting from an increase in the authorized number of directors, or from
failure of the shareholders to elect the full number of authorized directors),
may be filled by a majority vote of the remaining directors even though such
remaining directors constitute less than a quorum, provided that the
shareholders shall have the right at a special meeting called for that purpose
prior to such action by the Board, to fill the vacancy.

         DEPOSIT GUARANTY.  Under Deposit Guaranty's Bylaws, any vacancy,
including one occurring as a result of an increase in the number of directors,
may be filled only by the shareholders.

AMENDMENT OF THE ARTICLES OF INCORPORATION OR BYLAWS

         GONZALES HOLDING.   The Gonzales Holding Articles provide that the
amendment, repeal or adoption of any provision inconsistent with certain
provisions of its Articles and Bylaws generally containing supermajority voting
provisions requires a vote of 75% of the total voting power of Gonzales
Holding.  Otherwise, any amendment to the Articles requires only the
affirmative vote of two-thirds of the voting power present.  The Gonzales
Holding Bylaws provide that the Gonzales Holding Board may amend or repeal the
Gonzales Holding Bylaws, and the affirmative vote of 75% of the total voting
power of Gonzales Holding may amend or repeal any Bylaws at any annual or
special meeting, provided that notice of the proposed amendment or repeal was
contained in the notice of such meeting.

         DEPOSIT GUARANTY.  Under the Mississippi BCA, the board of directors
has the power to amend or repeal the bylaws of a Mississippi corporation such
as Deposit Guaranty, unless such power is expressly reserved for the
shareholders.  Deposit Guaranty's Articles provide that an amendment to the
Bylaws relating to composition of the Board of Directors and removal of
directors must be approved by the affirmative vote of at least eighty percent
(80%) of the shareholders (the same proportion required in order to effect the
removal of a director), excluding (except for purposes of determining whether a
quorum is present) those shares beneficially owned by any Interested
Shareholder.  The affirmative vote of at least eighty percent (80%) of the
shareholders is also required to amend the provisions of the Articles of
Incorporation requiring a supermajority approval of Business Combinations.
Amendments to the Articles of Incorporation that result in Dissenters' rights
require the affirmative vote of a majority of the outstanding shares entitled
to vote on the amendment.  Otherwise, the Articles of Incorporation may be
amended by a majority vote of the shares present at a meeting where a quorum is
present.

SPECIAL MEETINGS OF SHAREHOLDERS

         GONZALES HOLDING .  Under Gonzales Holding 's Bylaws, special meetings
of the shareholders, for any purpose or purposes, may be called by the
President or the Board of Directors, or, upon the written request of any two
directors or of any shareholder or shareholders holding in the aggregate not
less than one-fifth of the total voting power of Gonzales Holding 's voting
stock.

         DEPOSIT GUARANTY.  Under Deposit Guaranty's Bylaws, special meetings
of the shareholders, for any purpose or purposes, may be called by the Chairman
of the Board, the President or the Board of Directors, or upon the written
request of shareholders holding in the aggregate not less than ten percent
(10%) of the total voting power entitled to vote on an issue.

SHAREHOLDER PROPOSALS AND NOMINATIONS

         GONZALES HOLDING .  Neither Gonzales Holding 's Articles nor Bylaws
set forth any procedures with respect to submission by a shareholder of a
proposal for consideration at a shareholders' meeting.  The Gonzales Holding
Bylaws provide that any shareholder entitled to vote in the election of
directors may nominate any person for election as a director, provided the
nomination is made to the Secretary of the Corporation and received not less
than thirty (60) days or more than sixty (90) days prior to  the meeting;
provided, however, that if less than 60 days notice of the date of the meeting
is given or made to shareholders, notice by the shareholder to be timely must
be so received no later than the close of business on the 10th day following
the day on which such notice of the date of the meeting was mailed.

         DEPOSIT GUARANTY.  Deposit Guaranty's Bylaws provide procedures that
must be followed to properly bring a proposal before a shareholders meeting or
to nominate candidates for election as directors.  At least sixty (60) days
prior notice to the Secretary of Deposit Guaranty is required if a shareholder
intends to nominate an individual for election to the Board of Directors or
propose any shareholder action. These Bylaw provisions also require information
to be supplied about both the shareholder making such nomination or proposal
and the person nominated.


        MARKET PRICES OF AND DIVIDENDS ON GONZALES HOLDING COMMON STOCK

         No established public trading market for Gonzales Holding's common
stock exists.  The primary market area for Gonzales Holding's common stock is
Ascension Parish.  No sales of Gonzales Holding's common stock came to the
attention of management of Gonzales Holding in 1995 or 1994.  As of December
31, 1995,  there were 756 holders of record of Gonzales Holding Common Stock.

         In 1995 and 1994, Gonzales Holding paid eight quarterly dividends of
$0.35 per share, plus four extraordinary dividends totaling $8.00 per share,
for total dividends of $5,849,000.  The holders of Gonzales Holding Common
Stock are entitled to receive dividends when and if declared by the Gonzales
Holding Board out of funds that are legally available therefor.  If the Mergers
are not consummated, it is the intention of the Gonzales Holding Board to
continue declaring quarterly cash dividends.  However, there can be no
assurance that Gonzales Holding 's dividend policy would remain unchanged.

                    INFORMATION CONCERNING GONZALES HOLDING

GENERAL

         Gonzales Holding  is a Louisiana business corporation and a one-bank
holding company registered under the federal Bank Holding Company Act of 1956.
It was formed in 1983 primarily for the purpose of holding all of the
outstanding stock of the Gonzales Bank, which is  Gonzales Holding's sole
subsidiary.   Gonzales Bank was formed in 1920 under the banking laws of the
State of Louisiana.   Gonzales Bank conducts a general commercial banking
business through its main office at South Burnside Avenue and Worthey Road,
Gonzales, Louisiana and at two branch offices in eastern Ascension Parish,
Louisiana.   Gonzales Bank offers a full range of traditional commercial
banking services, including demand, savings and time deposits, consumer,
commercial and real estate loans, safe-deposit boxes and access to two retail
credit plans -- "VISA" and "MasterCard".   Gonzales Bank does not offer trust
services.  Drive-in banking facilities and automated teller machines ("ATMs")
are located at all three banking locations.   Gonzales Bank also maintains
three stand-alone ATMs within Ascension Parish.

COMPETITION

          Gonzales Bank competes actively with national and state banks and
savings and loan institutions in Louisiana for all types of loans and deposits.
Gonzales Bank also competes for loans with other financial institutions, such
as insurance companies, real estate investment trusts, savings and loans, small
loan companies, credit unions and certain government agencies.  As of December
31, 1995,  Gonzales Bank was the largest financial institution headquartered in
Ascension Parish as measured by total deposits and total assets.  Five other
financial institutions have a total of eleven banking offices located in
Ascension Parish.

EMPLOYEES

         As of December 31, 1995,  Gonzales Holding and  Gonzales Bank had
approximately 63 full time equivalent employees.   Gonzales Holding has no
salaried employees, although certain executive officers hold parallel positions
with  Gonzales Bank.  No employees are represented by unions or other
bargaining units, and management considers its relations with employees to be
satisfactory.

SUPERVISION AND REGULATION

          Gonzales Holding and  Gonzales Bank are extensively regulated under
both federal and state laws.  To the extent that the following information
describes particular statutory provisions, it is qualified in its entirety by
reference to the particular statutory and regulatory provisions.  Any change in
applicable law or regulation may have a material effect on the business and
prospects of  Gonzales Holding.

          Gonzales Holding is a bank holding company within the meaning of the
Bank Holding Company Act of 1956, as amended (the "BHCA"), and, as such, is
subject to the provisions of the BHCA and to regulation and supervision by the
Board of Governors of the Federal Reserve System (the "Reserve Board").
Gonzales Holding is required to file with the Reserve Board annual reports
containing such information as the Reserve Board may require pursuant to the
BHCA and also is subject to periodic examination by the Reserve Board.  The
BHCA limits, with certain exceptions, the business in which a bank holding
company may engage, directly or through subsidiaries, to banking, managing or
controlling banks, and furnishing or performing activities so closely related
to banking or managing or controlling banks as to be a proper incident thereto.
In determining whether a particular activity is a proper incident to banking or
managing or controlling banks, the Reserve Board must consider whether its
performance by an affiliate of a bank holding company can reasonably be
expected to produce benefits to the public, such as greater convenience,
increased competition or gains in efficiency that outweigh possible adverse
effects, such as undue concentration of resources, decreased or unfair
competition, conflicts of interest or other unsound banking practices.  The
Reserve Board has adopted regulations implementing the provisions of the BHCA





                                       27
<PAGE>   39


with respect to the activities of bank holding companies.  Whether or not a
particular non-banking activity is permitted under the BHCA, the Reserve Board
is authorized to require a bank holding company to terminate any activity or to
divest itself of any non-banking subsidiary if its actions represent unsafe or
unsound practices or violations of law.

         Under the BHCA, a bank holding company and its subsidiaries are
prohibited from engaging in certain tie-in arrangements in connection with the
extension of credit, the lease or sale of property or provision of any
services.  In addition, the BHCA prohibits a  bank holding  company from
borrowing from  its bank subsidiaries unless such loans are secured by
specified amounts and types of collateral.  Such secured loans are also subject
to certain limitations based upon the subsidiary bank's capital and surplus.

         The Federal Deposit Insurance Corporation Improvement Act of 1991 (the
"FDIC Act") subjected bank holding companies as well as banks to significantly
increased regulation and supervision.  Among other things, the FDIC Act
provides that undercapitalized institutions, as defined by regulatory
authorities, must submit recapitalization plans, and a parent company of such
an institution must either (i) guarantee the institution's compliance with the
capital plan, up to an amount equal to the lesser of five percent of the
institution's assets at the time it becomes undercapitalized or the amount of
the capital deficiency when the institution fails to comply with the plan, or
(ii) suffer certain adverse consequences such as a prohibition of dividends by
the parent company to its shareholders.

          Gonzales Holding is also subject to the Louisiana Bank Holding
Company Act, as amended (the "Louisiana Act") which, among other things,
provides that a bank holding company and its subsidiaries may not engage in any
insurance activity in which a bank may not engage.  The Louisiana Commissioner
of Financial Institutions is authorized to administer the Louisiana Act and to
issue orders and regulations thereunder.

         Federal and Louisiana laws provide for the enforcement of any pro rata
assessment of shareholders of a bank to cover impairment of capital stock by
sale, to the extent necessary, of the stock of any assessed shareholder failing
to pay the assessment.   Gonzales Holding, as shareholder of  Gonzales Bank, is
subject to these provisions.

         Both federal and state laws extensively regulate various aspects of
Gonzales Bank's business, including requirements regarding the maintenance of
reserves against deposits, limitations on the rates that can be charged on
loans or paid on deposits, branching and restrictions on the nature and amounts
of loans and investments that can be made.  As a state bank,  Gonzales Bank is
subject to the supervisory authority of the Louisiana Commissioner of Financial
Institutions, whose office conducts periodic examinations of  Gonzales Bank.
As a federally insured bank, Gonzales Bank is also subject to supervision and
regulation by the Federal Deposit Insurance Corporation (the "FDIC").  Under
certain circumstances, regulatory authorities may prohibit the payment of
dividends by a bank or its parent holding company.  The FDIC Act and
regulations promulgated thereunder classify banks into five categories
generally relating to their regulatory capital ratios and institute a system of
supervisory actions indexed to a bank's particular classification.  Generally,
banks that are classified as "well capitalized," or "adequately capitalized"
are not subject to the supervisory actions specified in the FDIC Act for prompt
corrective action, but may be restricted from taking certain  actions  that
will lower  their  classification.  Banks classified as "undercapitalized,"
significantly undercapitalized," or "critically undercapitalized" are subject
to restrictions in supervisory actions of increasing stringency based on the
level of classification.  Under present regulation,  Gonzales Bank is "well
capitalized."  While such a classification would exclude  Gonzales Bank from
the restrictions and actions envisioned by the prompt corrective action
provisions of the FDIC Act, the regulatory agencies have broad powers under
other provisions of federal law that would permit them to place restrictions on
Gonzales Bank or to take other supervisory action regardless of such
classification.

INVESTMENT PORTFOLIO

The following table sets forth the maturities of investment securities at
December 31, 1995 and the weighted average yields of such securities
(calculated on the basis of the cost and effective yields weighted for the
scheduled maturity of each security).  As discussed in the notes to the
consolidated financial statements, Gonzales Holding has an unused net operating
loss carry forward at December 31, 1995.  Accordingly, tax-equivalent

The provision for loan losses, which is charged to income from operations, is
based upon the changes in the loan portfolio, the amount of net loan losses
incurred, and management's estimation of potential future losses based on
several factors including, but not limited to, current economic conditions,
loan portfolio composition, nonaccrual loans, problem loans and prior loan loss
experience.

As a result of an improving economy and loan portfolio during 1994, management
determined that the allowance for possible loan losses exceeded the required
amount by $250,000 and credited the provision for possible loan losses for this
amount.

The following table shows an allocation of the allowance for possible loan
losses for each of the two years indicated (In thousands of dollars):

If nonaccrual loans had performed in accordance with their original terms,
interest income would have increased by approximately $17,000 in 1995 and
$11,000 in 1994.  Interest collected and recognized as interest income on these
loans was $9,000 in 1995 and $126,000 in 1994.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
          OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1995 AND 1994
                        GONZALES HOLDING AND SUBSIDIARY


         The purpose of this discussion is to focus on information about the
financial condition and results of operations of Gonzales Holding and Gonzales
Bank that is not otherwise apparent from the consolidated financial statements
and financial data presented elsewhere herein.

FINANCIAL CONDITION

         OVERVIEW.  Total assets of Gonzales Holding at December 31, 1995 and
1994 were $124,435,000 and $117,569,000, respectively, a $6,866,000 or 5.8%
increase.  Average assets for 1995 and 1994 were $121,664,000 and $117,916,000,
a 3.2% increase.  In order to better understand the reasons for the overall
increase in total assets, and likewise, in liabilities and shareholders'
equity, this discussion will focus on changes in the significant components of
Gonzales Holding's balance sheet.

         Cash and due from banks represent coin and currency on hand at
Gonzales Bank and amounts on deposit with correspondent banks, and are the
primary source for the daily withdrawal needs of depositors and credit needs of
loan customers.  At December 31, 1995 and 1994, cash and due from banks were
$5,068,000 and $4,957,000, an increase of $111,000.  Average cash and due from
banks were $4,161,000 in 1995 and $4,124,000 in 1994, which represents a
$37,000 or 0.9% increase.  As the largest nonearning asset on the balance
sheet, management closely monitors the level of cash on hand and in
correspondent banks as part of the overall asset/liability strategy, in order
to maintain a balance between the needs of customers and management's
obligation to endeavor to enhance shareholders' profits by assuring that the
level of all nonearning assets is minimized.

         Earning assets include federal funds sold, investment securities, and
loans and are Gonzales Holding's principal source of income.  Earning assets
averaged $113,403,000 in 1995 and $108,502,000 in 1994, a $4,901,000 or 4.5%
increase.  Total interest earned on these assets in 1995 and 1994 were
$9,981,000 and $8,940,000, respectively, which represents average yields of
8.80% and 8.24%.

         Banks must meet legal reserve requirements on a daily basis by
maintaining a specified level of currency and coin on hand plus funds on
deposit at Federal Reserve Banks.  Banks with excess reserves on a particular
day may sell the excess to other banks needing funds to meet their reserve
requirements on that day.  These federal funds sold represent unsecured loans
to other banks, usually on a daily basis, and are made at an agreed rate of
interest (the federal funds rate).  At December 31, 1995 and 1994, federal
funds sold were $2,634,000 and $627,000, respectively.  Average federal funds
sold were $1,763,000 in 1995 and $748,000 in 1994 and yielded 5.73% and 4.14%,
respectively.

         INVESTMENT SECURITIES.  Investment securities, in addition to
providing a source of income, are used to manage interest rate and liquidity
risk as part of Gonzales Bank's overall asset/liability strategy.  On January
1, 1994, Gonzales Bank adopted the Financial Accounting Standards Board's
Statement of Financial Accounting Standards number 115 (SFAS 115), "Accounting
for Certain Investments in Debt and Equity Securities."  Under SFAS 115,
investment securities of Gonzales Bank are classified as either
"held-to-maturity" or "available-for-sale."  Investments held-to-maturity are
bonds and notes for which Gonzales Bank has the positive intent and ability to
hold until their maturity, and are carried at cost, adjusted for amortization
of premiums and accretion of discounts.  Investments available-for-sale consist
of bonds and notes not classified as held-to-maturity and are carried at their
fair value.

         The carrying amounts of all investment securities at December 31, 1995
and 1994 were $52,759,000 and $47,003,000.  At December 31, 1995 and 1994, the
amortized costs of all investment securities (available-for-sale and
held-to-maturity) were $52,304,000 and $49,138,000, respectively, and the fair
values were $52,682,000 and $46,083,000.  Average carrying amounts of
investments were $51,262,000 in 1995 and $48,325,000 in 1994, which include
average unrealized losses on securities available-for-sale of $709,000 and
$901,000, respectively.  The decrease in interest rates in 1995 caused an
increase in the fair values of the securities.  At the end of 1994, the fair
value of all securities was $3,054,000

less than the amortized cost.  At the end of 1995, the fair value was $378,000
more than  the amortized cost.  Of this $378,000 net  unrealized gain at
December 31, 1995, unrealized gains of $455,000 have increased the carrying
amount of securities available-for-sale, while unrealized losses of $77,000
have not affected the carrying amount of the securities held-to-maturity, which
are carried at amortized cost.  The average amortized cost of the investment
securities increased by $2,745,000, from $49,226,000 in 1994 to $51,971,000 in
1995.

         LOANS.  Gonzales Holding's primary use of funds is for loan demand.
Loans outstanding at the end of 1995 and 1994 were $59,573,000 and $59,670,000,
a decrease of only $97,000 or 0.2%.  Average loans outstanding for 1995 and
1994 were $60,049,000 and $59,352,000, a $697,000 or 1.2% increase.  Interest
income generated from loans was $6,437,000 for 1995 and $6,114,000 for 1994,
for average yields of 10.72% and 10.30%, respectively.  The increase in average
yield on loans does not reflect the general decrease in interest rates which
occurred during the latter part of 1995.  Management expects average loans to
continue to increase due to the continued strong economic environment,
aggressive marketing strategies, and the decline in rates.

         DEPOSITS.  Deposits are Gonzales Holding's primary  source of funds.
Total  deposits at December 31, 1995 and 1994 were $108,180,000 and
$102,527,000, respectively.  Deposits averaged $105,523,000 in 1995 and
$101,687,000 in 1994, a $3,836,000 or 3.8% increase.  Interest-bearing deposits
in 1995 and 1994 averaged $84,253,000 and $81,588,000.  Interest expense for
these deposits was $3,036,000 in 1995 and $2,289,000 in 1994, for average rates
paid of 3.60% and 2.81%.  Although rates began falling during the latter part
of 1995, the average rates paid in 1995 remained higher than the 1994 average.

         Stockholders' equity increased from $11,042,000 at December 31, 1994
to $12,435,000 at December 31, 1995 due to net income in 1995 of $2,611,000,
dividends declared of $2,925,000, and an increase during 1995 in the fair
values of investment securities available-for-sale, net of deferred income
taxes, of $1,707,000.  During 1995 and 1994, Gonzales Holding paid regular
dividends of $0.35 per share per quarter, plus $4.00 per share per year in
extraordinary dividends.

RESULTS OF OPERATIONS

         NET INTEREST INCOME.  Net income for 1995 and 1994 was $2,611,000 and
$2,626,000, respectively, a $15,000 or 0.6% decrease.

         Net interest income is the difference between interest income from
loans, investments, and other interest- earning assets and interest expense on
deposits and other interest-bearing liabilities.  Net interest income for 1995
and 1994 was $6,723,000 and $6,452,000, a $271,000 or 4.2% increase.  The
various components of net interest income as they relate to the particular
interest-earning assets and interest-bearing liabilities have been discussed in
the previous section titled "Financial Condition."  The net interest margin
(that is, net interest income divided by average interest-earning assets) was
5.93% in 1995 and 5.95% in 1994.  With close monitoring of the rates, along
with proper asset/liability management, the net interest margin will be managed
to maximize profits under both falling and rising interest rate environments.

         PROVISION FOR LOAN LOSSES.  The provision for possible loan losses is
based on changes in the loan portfolio, the amount of net loan losses incurred,
and management's estimates of potential future losses based on several factors
including, but not limited to, current economic conditions, loan portfolio
composition, prior loan loss experience, and the level of impaired and other
problem loans.  The continued improvement of the economy and reduction of
nonperforming and other problem loans contributed to management's decision to
reduce the allowance for possible loan losses by $250,000 in 1994 through a
credit to operations.  In 1995, the allowance decreased by $108,000 due to net
charge-offs of $168,000 offset by a charge to operations for the provision for
loan losses of $60,000.  Gonzales Holding adopted Statement of Financial
Accounting Standard number 114, "Accounting by Creditors for Impairment of a
Loan," in 1995, which did not have a material effect on financial condition or
the results of operations.  Loans which have been identified by management as
impaired generally include nonaccrual loans, loans past due ninety days or more
and still accruing, loans which have previously had some portion classified as
either loss or doubtful, and other loans which for specific reasons have been
identified as impaired.  At December 31, 1995, loans totaling $1,746,000 were
specifically classified as impaired.  Nonperforming loans at December 31, 1994
include nonaccrual loans, loans which are past due ninety days or more as to
principal or interest payments and still accruing, and loans for which the
terms have been restructured due to the financial troubles of borrowers.  Total
nonperforming loans at December 31, 1994 were $1,222,000.  In addition,
management has





                                       39

identified other loans which are contractually current and not classified as
either impaired or nonperforming, but the borrowers are experiencing financial
difficulties.  These other loans totaled $2,282,000 at the end of 1995 and
$1,895,000 at the end of 1994.

         NON-INTEREST INCOME.  Noninterest income was $1,419,000 for 1995 and
$1,477,000 for 1994.  Noninterest income consists primarily of service charges
on deposit accounts and fees for other financial services, which were
$1,164,000 in 1995 and $1,126,000 in 1994, a $38,000 or 3.3% increase.  This
increase is directly attributable to the 3.6% increase in demand, NOW, money
market, and savings accounts during 1995.  The net income from operation of
foreclosed real estate was $60,000 in 1995 and $142,000 in 1994.  The major
portion of these amounts were from credits to the provision for loss on
foreclosed real estate of $40,000 in 1995 and $100,000 in 1994.

         NON-INTEREST EXPENSE.  Noninterest expense was $4,241,000 for 1995 and
$4,302,000 for 1994, a $61,000 or 1.4% decrease.  This decrease is attributable
principally to two components of noninterest expense:  (1) net occupancy
expense, which was $307,000 in 1995 and $346,000 in 1994, a $39,000 decrease,
and (2) equipment expense, which was $347,000 in 1995 and $373,000 in 1994, a
$26,000 decrease. The decrease in net occupancy expense was primarily due to a
$28,000 reduction in building repairs and maintenance.  The decrease in
equipment expense was primarily due to a $36,000 decrease in depreciation
expense on furniture, equipment and automobiles.

         Income tax expense was $1,230,000 and $1,251,000 for 1995 and 1994.
These provisions for taxes include current expenses of $93,000 in 1995 and
$66,000 in 1994, which represent alternative minimum tax that Gonzales Holding
has paid.  These taxes are expected to be recovered in future years as credit
carryovers when Gonzales Holding again begins incurring taxes under the regular
income tax system.

LIQUIDITY AND CAPITAL RESOURCES

         The primary functions of asset/liability management are to assure
adequate liquidity and to maintain an appropriate balance between
interest-earning assets and interest-bearing liabilities.  Liquidity management
involves the ability to meet the cash flow requirements of customers who may be
either depositors wanting to withdraw funds or borrowers needing assurance that
sufficient funds will be available to meet their credit needs.  The principal
sources of liquidity for Gonzales Holding are cash and due from bank accounts,
investment securities which are available-for- sale, federal funds sold,
maturing loans, short-term borrowings through federal funds lines of credit,
and advances from the Federal Home Loan Bank.

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

         Quantitative measures established by regulation to ensure capital
adequacy require Gonzales Bank to maintain minimum amounts and ratios of total
and Tier 1 capital, as defined in the regulations, to risk-weighted assets, as
defined, and of Tier 1 capital to average assets, as defined.  Management
believes, as of December 31, 1995, that Gonzales Bank meets all capital
adequacy requirements to which it is subject.

         As of December 31, 1995, the most recent notification from the Federal
Deposit Insurance Corporation categorized Gonzales Bank as well capitalized
under the regulatory framework for prompt corrective action.  To be categorized
as well capitalized, Gonzales Bank must maintain a total risk-based capital
ratio of 10% or higher, Tier 1 risk-based capital ratio of 6% or higher, and
Tier 1 leverage capital ratio of 5% or higher.  No conditions or events have
occurred since that notification that management believes have changed Gonzales
Bank's category.

                          INDEPENDENT AUDITORS' REPORT



To the Shareholders and Board of Directors
of Bank of Gonzales Holding Company, Inc.


We have audited the accompanying consolidated statements of financial condition
of Bank of Gonzales Holding Company, Inc. and its subsidiary as of December 31,
1995 and 1994, and the related consolidated statements of income, shareholders'
equity, and cash flows for the years then ended.  These consolidated financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial statements
are free of material misstatement.  An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the consolidated
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 financial position of Bank of Gonzales

in conformity with generally accepted accounting principles.

BANK OF GONZALES HOLDING COMPANY, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 1995 AND 1994


NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting principles followed by Bank of Gonzales Holding Company, Inc.
(the Company) and its wholly-owned subsidiary, Bank of Gonzales (the Bank), and
the methods of applying those principles conform with generally accepted
accounting principles consistently applied and generally practiced within the
banking industry.  The principles which significantly affect the determination
of financial condition and net income are summarized below:

Principles of Consolidation:  The consolidated financial statements include the
accounts of the Company and the Bank.  All significant intercompany balances
and transactions have been eliminated.  Investment in the Bank is carried at
the Company's equity in the underlying net assets.

Nature of operations:  The Bank provides a variety of financial services to
individual and business customers through its three offices in Ascension
Parish, Louisiana, which is primarily an industrial area.  The Bank's primary
deposit products are checking and savings accounts and certificates of deposit.
Its primary lending products are commercial, real estate and consumer loans.

Use of estimates:  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.

Material estimates that are particularly susceptible to significant change
relate to the determination of the allowance for losses on loans and the
valuation of real estate acquired in connection with foreclosures or in
satisfaction of loans.  In connection with the determination of the allowances
for losses on loans and foreclosed real estate, management obtains independent
appraisals for significant properties.

While management uses available information to recognize losses on loans and
foreclosed real estate, future additions to the allowances may be necessary
based on changes in local economic conditions, which depends heavily on the
petrochemical industry.  In addition, regulatory agencies, as an integral part
of their examination process, periodically review the Bank's allowances for
losses on loans and foreclosed real estate.  Such agencies may require the Bank
to recognize additions to the allowances based on their judgments about
information available to them at the time of their examination.  Because of
these factors, it is reasonably possible that the allowances for losses on
loans and foreclosed real estate may change materially in the near term.

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

    Securities Held-to-Maturity.  Bonds and notes 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 the interest method over the period to
    maturity.

    Securities Available-for-Sale.  Securities available-for-sale consist of
    bonds and notes not classified as securities held-to-maturity.

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.  The
related write-downs are included in earnings as realized losses.  Unrealized
holding gains and losses, net of tax, on securities available- for-sale are
reported as a net amount in a separate component of shareholders' equity until
realized.  Gains and losses on the sale of securities available-for-sale are
determined using the specific-identification method.





                                      F-7
<PAGE>   60
Loans Receivable and Allowance for Loan Losses:  Loans are stated at the amount
of unpaid principal reduced by unearned income and the allowance for loan
losses.  Unearned income on discounted loans is recognized as income over the
term of the loans using a method that approximates the interest method.
Interest on other loans is calculated by using the simple interest method on
daily balances of the principal amount outstanding.  Loans are generally placed
on nonaccrual when principal or interest is delinquent for ninety days or more.
Interest income generally is not recognized on nonaccrual loans unless the
likelihood of further loss is remote.  Interest payments received on such loans
are applied as a reduction of the loan principal balance.  Impaired loans
generally include nonaccrual loans, loans past due ninety days or more and
still accruing, and restructured loans.  Loans reviewed for impairment include
all loans (except consumer installment loans, which are generally smaller
balance, homogeneous loans) which management has identified as warranting
special attention, such as past due loans, large loans, and loans for which
management is aware of a borrower's financial difficulties.

The allowance for loan losses represents an amount which, in management's
judgment, will be adequate to absorb possible losses on existing loans that may
become uncollectible.  The amount of the allowance is based on management's
evaluation of the collectibility of the loan portfolio, including the nature of
the portfolio, credit concentrations, trends in historical loss experience,
specific impaired loans, and economic conditions.  Allowances for impaired
loans are generally determined based on collateral values.  Ultimate losses may
vary from current estimates.  A loan is charged off when it is determined to be
uncollectible.  The allowance is increased by a provision for loan losses,
which is charged to expense, and reduced by charge-offs, net of recoveries.

Premises and Equipment:  Premises and equipment are stated at cost less
accumulated depreciation.  Repairs and maintenance expenditures which extend
the useful life of an asset are capitalized, and routine maintenance and repair
expenditures are expensed as incurred.  Depreciation expense is computed using
the straight-line method over the estimated useful lives of the respective
assets.

Foreclosed Real Estate:  Foreclosed real estate is comprised of properties
acquired through foreclosure proceedings or acceptance of deed in lieu of
foreclosure.  These properties are carried at the lower of cost or estimated
fair market value.  Losses arising at the time of acquisition of such property
are charged against the allowance for loan losses.  Subsequent losses are
included in net income from operation of foreclosed real estate.

Federal Income Taxes:  Provision for deferred income taxes is made as a result
of temporary differences between the financial and taxable bases of assets and
liabilities.  These differences relate principally to the provision for
possible loan losses, foreclosed real estate expense, accretion of discounts on
investment securities, and the tax net operating loss carryforward.

Statement of Cash Flows:  For purposes of the statement of cash flows, the
Company considers due from bank accounts and federal funds sold to be cash
equivalents.

Treasury Stock:  Treasury stock is accounted for by the cost method on an
average cost basis.

Fair Values of Financial Instruments:  Statement of Financial Accounting
Standards number 107, "Disclosures about Fair Value of Financial Instruments,"
requires disclosure of  fair value  information about  financial instruments,
whether or not recognized in the statement of financial condition.  In cases
where quoted market prices are not available, fair values are based on
estimates using present value or other valuation techniques.  Those techniques
are significantly affected by the assumptions used, including the discount rate
and estimates of future cash flows.  In that regard, the derived fair value
estimates cannot be substantiated by comparison to independent markets and, in
many cases, could not be realized in immediate settlement of the instruments.
Statement 107 excludes certain financial instruments and all nonfinancial
instruments from its disclosure requirements.  Accordingly, the aggregate fair
value amounts presented do not represent the underlying value of the Company.

Reclassifications:  Certain items included in the financial statements for 1994
have been reclassified to conform with the 1995 presentation and have no effect
on net income previously reported.

NOTE B--RESTRICTIONS ON SHAREHOLDERS' EQUITY

Under applicable law, the Bank cannot, without the prior approval of regulatory
authorities, pay dividends during any year which exceed the combined net income
of that year and the immediately preceding year.  Additionally, under
applicable law, the Bank cannot make loans, extensions of credit, repurchase
agreements, investments, or advances, which will exceed 10% of its capital
stock and surplus, to an affiliate.  At December 31, 1995, the Bank had no such
loans or advances to its affiliate.


NOTE C--RESTRICTIONS ON CASH AND DUE FROM BANKS

The Bank is required to maintain average reserve balances with the Federal
Reserve Bank.  The average amount of these reserve balances for the years ended
December 31, 1995 and 1994 was approximately $811,000 and $787,000,
respectively.


NOTE D--INVESTMENT SECURITIES

Expected maturities will differ from contractual maturities because borrowers
may have the right to call or prepay obligations with or without call or
prepayment penalties.  Proceeds from sales of investments in debt securities
during 1995 and 1994 were $12,790,000 and $19,976,000, respectively. Gross gains
of $74,000 in 1995 and $111,000 in 1994, and gross losses of $124,000 in 1995
and $155,000 in 1994, were realized on those sales.

The Bank owns stock in the Federal Home Loan Bank of approximately $572,000
which was pledged to partially secure a line of credit totaling $6,204,000.
Quarterly stock dividends are paid and the Federal Home Loan Bank will
repurchase the stock at par if no advances are outstanding.

The Bank adopted Statement of Financial Accounting Standards number 114,
"Accounting by Creditors for Impairment of a Loan," in 1995, which did not have
a material effect on financial condition or the results of operations.  At
December 31, 1995, loans totaling $1,746,000 were specifically classified as
impaired.  Of the total impaired loans at December 31, 1995, $416,000 had a
related allowance for loan losses of $104,000.  The average balance of these
loans in 1995 was approximately $2,178,000.  In 1995, interest income
recognized on these loans was approximately $175,000.  No commitments to loan
additional funds to borrowers of impaired loans were outstanding at December
31, 1955.

Nonperforming loans at December 31, 1994, prior to the adoption of Statement
114, consist of nonaccrual loans, past due loans and restructured loans.
Nonaccrual loans are loans on which interest recognition has been suspended
until realized because of doubts as to the borrower's ability to repay
principal or interest.  Past due loans are accruing loans that are
contractually past due 90 days or more as to principal or interest.
Restructured loans are loans whose terms have been modified, because of a
deterioration in financial condition of the borrower, to provide for a
reduction of either interest or principal payments.  The following table
summarizes the Company's nonperforming and restructured loans at December 31,
1994, in thousands of dollars:

<TABLE>
    <S>                                            <C>
    Nonaccrual loans                               $   123
    Accruing loans past due 90 days or more        $    23
    Restructured loans                             $ 1,076
</TABLE>

In 1994, if nonaccrual loans had performed in accordance with their original
terms, interest income would have increased by approximately $11,000.  Interest
collected and recognized as interest income on these loans in 1994 was
$126,000.

In addition, at December 31, 1995 and 1994, the Bank had approximately
$2,282,000 and $1,895,000, respectively, of loans which were contractually
current and not considered impaired or nonperforming, but the borrowers were
experiencing financial difficulties.


NOTE F--TRANSACTIONS WITH RELATED PARTIES

Loans have been made to directors, principal shareholders and executive
officers and their associates.  The balance of such loans at December 31, 1995
and 1994 was $5,091,000 and $5,542,000, respectively.  During 1995, new loans
of $755,000 were made and repayments of $1,206,000 were received.  There were
no nonaccrual, past due and other loans to related parties who are currently
experiencing financial difficulties at December 31, 1995 and 1994.

At December 31, 1995 and 1994 related parties had deposit balances totaling
approximately $4,016,000 and $3,587,000, respectively.

Consulting and other service fees amounting to approximately $9,000 in 1995 and
$9,000 in 1994 have been paid to business affiliates of certain directors.

NOTE I--PENSION PLAN

In 1989, the Bank established a 401(k) profit sharing plan and trust ("cash or
deferred arrangement").  Under the plan, all employees who were employed at
January 1, 1989, the effective date, are eligible to participate.  Other
employees become eligible on the first January 1 or July 1 following their
attaining age 21 and completing 3 months of service.  Participants may elect to
defer from 1% up to 15% of their compensation as elective contributions.  The
Bank is not required to match employee contributions, but is permitted to make
a discretionary contribution that would be allocated to all participants based
on compensation.  The Bank contributed $30,000 to the plan in 1995.  No
contributions were made by the Bank in 1994.

letters of credit, which involve credit risk in excess of the amounts
recognized in the balance sheets.  The Bank's exposure to credit loss in the
event of nonperformance by the other party to these financial instruments is
represented by the contractual amounts of the instruments.  The Bank uses the
same credit policies in making commitments and conditional obligations as it
does for on-balance sheets instruments, including collateral or other security
to support the financial instruments.

At December 31, 1995 and 1994, commitments to extend credit totaled $5,873,000
and $5,485,000, respectively.  These commitments are agreements to lend to a
customer as long as there is no violation of any condition established in the
contract.  Commitments generally have fixed expiration dates or other
termination clauses and may require payment of a fee.  Since many of the
commitments may expire without being drawn upon, the total commitment amounts
do not necessarily represent future cash requirements.

At December 31, 1995 and 1994, commitments under standby letters of credit
totaled $210,000 and $98,000, respectively.  Standby letters of credit are
conditional commitments issued by the Bank to guarantee the performance of a
customer to a third party.  The credit risk involved in issuing letters of
credit is essentially the same as that involved in extending loans to
customers.

The estimated fair values of Gonzales Holding's financial instruments at
December 31, 1995 are as follows:

The following methods and assumptions were used by Gonzales Holding in
estimating fair values of financial instruments:

Cash, due from banks, federal funds sold, and interest-bearing deposits in
banks.  The carrying amount is a reasonable estimate of fair value.

Securities.  Fair value is based on quoted market price, if available.  If a
quoted market price is not available, fair value is estimated using quoted
market prices for similar securities.

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





                                      F-18
<PAGE>   71
Deposits.  The fair value of demand, savings, NOW and money market accounts is
the amount payable on demand at the reporting date.  The fair value of
fixed-maturity time deposits is estimated using the rates currently offered for
deposits of similar remaining maturities.

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

Commitments to extend credit and standby letters of credit.  The fair value is
estimated using the fees currently charged to enter into similar agreements,
taking into account the remaining terms of the agreements and the present
creditworthiness of the counterparties.

NOTE P--CONTINGENCIES

Gonzales Bank has entered into agreements with its senior officers (total of
four persons) that, should the Bank terminate their employment for any reason,
other than for cause, death or permanent disability, within two years after a
change in control, each would be entitled to a lump sum payment of twice their
annual compensation reduced by amounts paid by the Bank after a change in
control.  In addition, should the president of Gonzales Bank be terminated,
other than for cause, death, or permanent disability, prior to December 31,
1998, Gonzales Bank would be obligated to pay as severance pay the present
value of the remaining salary due him through December 31, 1998 in the form of
a lump sum.

NOTE R--REGULATORY MATTERS

The Bank is subject to various regulatory capital requirements administered by
the federal banking agencies.  Failure to meet minimum capital requirements can
initiate certain mandatory, and possibly discretionary, actions by regulators
that, if undertaken, could have a direct material effect on the Bank's
financial statements.  Under capital adequacy guidelines and the regulatory
framework for prompt corrective action, the Bank must meet specific capital
guidelines that involve 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.

Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios of total and Tier 1
capital, as defined in the regulations, to risk-weighted assets, as defined,
and of Tier 1 capital to average assets, as defined.  Management believes, as
of December 31, 1995, that the Bank meets all capital adequacy requirements to
which it is subject.

As of December 31, 1995, the most recent notification from the Federal Deposit
Insurance Corporation categorized the Bank as well capitalized under the
regulatory framework for prompt corrective action.  To be categorized as well
capitalized, the Bank must maintain a total risk-based capital ratio of 10% or
higher, Tier 1 risk-based capital ratio of 6% or higher, and Tier 1 leverage
capital ratio of 5% or higher.  No conditions or events have occurred since
that notification that management believes have changed the Bank's category.


NOTE S--SUBSEQUENT EVENTS

On January 18, 1996, Gonzales Holding's Board of Directors voted to merge the
Company with Deposit Guaranty Corporation (the "Acquiror") of Mississippi.  The
Bank will become a branch of a subsidiary owned by the Acquiror, and
shareholders of the Company will receive approximately 1.17 shares of the
Acquiror's common stock in exchange for each share of their Company common
stock.  The merger is subject to the approval of the Company's shareholders and
appropriate regulatory authorities.  Such approval is expected by June, 1996.


NOTE T--IMPAIRMENT OF LONG-LIVED ASSETS

The Company will adopt Statement of Financial Accounting Standards number 121
(SFAS 121), "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," in 1996.  SFAS 121 requires that
long-lived assets be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable, and that an impairment loss be recognized if the sum of the future
cash flows from the use of the asset is less than the carrying amount.
Management expects that the adoption of SFAS 121 in 1996 will result in a
charge to operations of approximately $190,000 related to the carrying amount
of certain Bank premises.

                          AGREEMENT AND PLAN OF MERGER


         This AGREEMENT AND PLAN OF MERGER, dated as of February 5, 1996, by
and among Bank of Gonzales Holding Company, Inc. ("Gonzales Holding"), a
corporation organized under the laws of the State of Louisiana, and its
wholly-owned subsidiary Bank of Gonzales ("Gonzales Bank"), a state banking
association organized under the laws of Louisiana, and Deposit Guaranty Corp.
("DGC"), a corporation organized under the laws of the State of Mississippi,
its wholly-owned subsidiary Commercial National Corporation ("CNC"), a
corporation organized under the laws of Louisiana, and CNC's wholly-owned
subsidiary Citizens National Bank ("CNB"), a banking association organized
under the laws of the United States, each acting pursuant to a resolution of
its Board of Directors.

         In consideration of the mutual covenants, representations, warranties
and agreements herein contained, the parties agree that Gonzales Holding shall
be merged into CNC (the "Holding Company Merger") on the terms and subject to
the conditions set forth in this Agreement and simultaneously therewith or
immediately following the Holding Company Merger, Gonzales Bank shall be merged
into CNB (the "Bank Merger" and together with the Holding Company Merger, the
"Mergers"), on the terms and subject to the conditions set forth in this
Agreement.

                                   Article I.

                           THE HOLDING COMPANY MERGER

         1.01    Holding Company Merger.  In accordance with the applicable
provisions of the Louisiana Business Corporation Law ("LBCL"), Gonzales Holding
shall be merged with and into CNC pursuant to a certificate of merger
substantially in the form attached as Exhibit A and  executed and acknowledged
in the manner required by law; the separate existence of Gonzales Holding shall
cease; and CNC shall be the corporation surviving the Holding Company Merger.

         1.02    Effective Date of the Holding Company Merger.  The Holding
Company Merger shall become effective on the date (the "Effective Date") set
forth in the certificate of merger filed in the office of the Secretary of
State of Louisiana.

         1.03    Effect of the Holding Company Merger.  On the Effective Date,
(i) the separate existence of Gonzales Holding shall cease and Gonzales Holding
shall be merged with and into CNC, (ii) CNC shall continue to possess all of
the rights, privileges and franchises possessed by it and shall, on the
Effective Date, become vested with and possess all rights, privileges and
franchises possessed by Gonzales Holding, (iii) CNC shall be responsible for
all of the liabilities and obligations of Gonzales Holding in the same manner
as if CNC had itself incurred such liabilities or obligations, and the Holding
Company Merger shall not affect or impair the rights of the creditors or of any
persons dealing with Gonzales Holding, (iv) the Holding Company Merger will not
of itself cause a change, alteration or amendment to the Articles of
Incorporation or the Bylaws of CNC, (v) the Holding Company Merger will not of
itself affect the tenure in office of any officer or director of CNC and no
such person will succeed to such positions solely by virtue of the Holding
Company Merger, and (vi) the Holding Company Merger shall, from and after the
Effective Date, have all the effects provided by applicable Louisiana law.

         1.04    Additional Actions.  If, at any time after the Effective Date,
CNC shall consider or be advised that any further assignments or assurances in
law or any other acts are necessary or desirable (i) to vest, perfect or
confirm, of record or otherwise, in CNC, title to or the possession of any
property or right of Gonzales Holding acquired or to be acquired by reason of,
or as a result of, the Holding Company Merger, or (ii) otherwise to carry out
the purposes of this Agreement, Gonzales Holding and its proper officers and
directors shall be deemed to have granted to CNC an irrevocable power of
attorney to execute and deliver all such proper deeds, assignments and
assurances in law and to do all acts necessary or proper to vest, perfect or
confirm title to and possession of such property or rights in CNC and otherwise
to carry out the purposes of this Agreement; and the proper officers and
directors of CNC are fully authorized in the name of Gonzales Holding to take
any and all such action.

         1.05    Conversion of Gonzales Holding Shares.  Each share of common
stock, no par value, of Gonzales Holding (the "Gonzales Holding Common Stock")
issued and outstanding immediately prior to the Effective Date other than
shares of Gonzales Holding Common Stock owned by stockholders who, pursuant to
the LBCL, perfect dissenters' rights ("Dissenting Shares"), shall, by virtue of
this Agreement and without any action on the part of the holder thereof, be
converted into and exchangeable for the number of shares of common stock, no
par value, of DGC (the "DGC Common Stock") equal to the Exchange Ratio, as
defined below, subject to adjustment as provided herein and, in respect of
fractional shares, subject to Section 1.06 hereof.  The Exchange Ratio shall
equal 634,000 divided by the number of shares of Gonzales Holding Common Stock
outstanding on the date immediately preceding the Effective Date.  If prior to
the Effective Date DGC should split or combine DGC Common Stock, or pay a
dividend or other distribution in DGC Common Stock, then the exchange ratio
shall be appropriately adjusted to reflect such split, combination, dividend or
distribution.

         1.06    Exchange of Shares.  (a)  As soon as practicable after the
Effective Date, Deposit Guaranty National Bank, acting as exchange agent (the
"Exchange Agent"), shall mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Date represented issued
and outstanding shares of Gonzales Holding Common Stock (the "Certificates"), a
form letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
delivery of the Certificates to the Exchange Agent) and instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing DGC Common Stock.  Upon surrender of a Certificate for exchange
and cancellation to the Exchange Agent, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing that number of shares
of DGC Common Stock to which such holder of Gonzales Holding Common Stock shall
have become entitled pursuant to the provisions hereof, and the Certificate so
surrendered shall forthwith be cancelled.  Lost Certificates shall be treated
in accordance with the existing procedures of Gonzales Holding.

         (b)     No dividends or other distributions declared after the
Effective Date with respect to DGC Common Stock and payable to the holders of
record thereof after the Effective Date shall be paid to the holder of any
unsurrendered Certificate until the holder thereof shall surrender such
Certificate.  Subject to the effect, if any, of applicable law, after the
subsequent surrender and exchange of a Certificate, the record holder thereof
shall be entitled to receive any such dividends or other distributions, without
any interest thereon, which theretofore had become payable with respect to the
shares of DGC Common Stock into which the shares represented by such
certificate have been converted.

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

         (d)     After the Effective Date there shall be no transfers on the
stock transfer books of Gonzales Holding of the shares of Gonzales Holding
Common Stock which are outstanding immediately prior to the Effective Date.
If, after the Effective Date, Certificates representing such shares are
presented for transfer to the Exchange Agent, they shall be cancelled and
exchanged for certificates representing shares of DGC Common Stock as provided
herein.

         (e)     No certificates or scrip representing fractional shares of DGC
Common Stock shall be issued upon the surrender for exchange of such
Certificates, no dividend or distribution with respect to DGC Common Stock
shall be payable on or with respect to any fractional share, and such
fractional share interests shall not entitle the owner thereof to vote or to
any other rights of a shareholder of DGC.  In lieu of any such fractional
share, DGC shall pay to each former stockholder of Gonzales Holding who
otherwise would be entitled to receive a fractional share of DGC Common Stock
an amount in cash determined by multiplying (i) the closing sale price of a
share of DGC Common Stock on the date immediately proceeding the Effective Date
as quoted on the National Association of Securities Dealers Automated Quotation
System, by (ii) the fraction of a share of DGC Common Stock to which such
holder would otherwise be entitled.





                                       2
<PAGE>   79
         1.07    DGC to Make Shares Available.  DGC shall make available a
sufficient number of shares for conversion and exchange in accordance with
Section 1.05, by transferring such shares to the Exchange Agent for the benefit
of the stockholders of Gonzales Holding.

         1.08    Shares of CNC.  The shares of capital stock of CNC outstanding
immediately prior to the Effective Date shall not be changed or converted by
virtue of the Holding Company Merger.

         1.09    Tax Consequences.  It is intended that the Holding Company
Merger shall constitute a reorganization within the meaning of Section
368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the "Code"), and
that this Agreement shall constitute a "plan of reorganization" within the
meaning of Section 368 of the Code.


                                  Article II.

                                THE BANK MERGER

         2.01    The Bank Merger.  On the Effective Date (as defined in 
Section 2.02 hereof), Gonzales Bank shall be merged with and into CNB under the
Articles of Association of CNB, as amended, existing under Charter No. 13648,
pursuant to the provisions of, and with the effect provided in, 12 U.S.C.
Section  215a and La. R.S. 6:351 et seq.  On the Effective Date, CNB, the
Receiving Association, shall continue to be a national banking association, and
its business shall continue to be conducted at its main office in Hammond,
Louisiana, and at its legally established branches (including, without
limitation, the legally established offices from which Gonzales Bank conducted
business immediately prior to the Effective Date).  The Articles of Association
of CNB shall not be altered or amended by virtue of the Bank Merger, and the
incumbency of the directors and officers of CNB shall not be affected by the
Bank Merger nor shall any person succeed to such positions by virtue of the Bank
Merger.  CNB shall file this Agreement with the Louisiana Commissioner of
Financial Institutions (the "Commissioner") pursuant to La. R.S. 6:352 and make
appropriate filings with the Office of the Comptroller of the Currency (the
"OCC").  Gonzales Bank and CNB are sometimes referred to together as the
"Merging Associations."

         2.02      Effective Date. The Bank Merger shall become effective on
the Effective Date.

         2.03      Cancellation of Capital Stock of Gonzales Bank.  On the
Effective Date, by virtue of the Bank Merger, all shares of the capital stock
of Gonzales Bank shall be cancelled and no cash, securities or other property
shall be issued in the Bank Merger in respect thereof.

         2.04      Capital Structure of the Receiving Association.  As of
December 31, 1995, CNB had capital of $2,341,210 divided into 234,121 shares of
common stock authorized, each of $10 par value ("CNB Common Stock"), surplus of
$3,603,351 and undivided profits, including capital reserves, of $12,480,851.
As of December 31, 1995, Gonzales Bank had capital of $4,400,000 divided into
440,000 shares of common stock authorized, each of $10  par value, surplus of
$8,506,000  and an accumulated deficit, including capital reserves, of
$775,000.

         On the Effective Date, the amount of capital of the Receiving
Association shall be $2,341,210 divided into 234,121 shares of common stock,
each of the par value of $10, and on the Effective Date, the Receiving
Association shall have a surplus of $3,603,351, plus the value of the
consideration to be paid by DGC in the Holding Company Merger, and undivided
profits, including capital reserves, which when combined with capital and
surplus will be equal to the capital structure of CNB, as set forth above,
adjusted, however, for the results of operations of CNB between December 31,
1995 and the Effective Date.

         2.05      Effects of the Bank Merger.  On the Effective Date, the
corporate existence of each of the Merging Associations shall be merged into
and continued in CNB, the Receiving Association, and such Receiving Association
shall be deemed to be the same corporation as each bank or banking association
participating in the Bank Merger.  All rights,





                                       3
<PAGE>   80
franchises and interests of the individual Merging Associations in and to every
type of property (real, personal and mixed) and choses in action shall be
transferred to and vested in the Receiving Association by virtue of the Bank
Merger without any deed or other transfer.  The Receiving Association, upon the
Bank Merger and without any order or other action on the part of any court or
otherwise, shall hold and enjoy all rights of property, franchises and
interests, including appointments, designations and nominations, and all other
rights and interests as trustee, executor, administrator, registrar of stocks
and bonds, guardian of estates, and in every other fiduciary capacity, in the
same manner and to the same extent as such rights, franchises and interests
were held or enjoyed by any one of the Merging Associations at the time of the
Bank Merger, subject to the conditions specified in 12 U.S.C. Section  215a(f).
The Receiving Association shall, from and after the Effective Date, be liable
for all liabilities of the Merging Associations.

         2.06      Tax Consequences.  It is intended that the Bank Merger shall
constitute a tax-free reorganization pursuant to Section 368(a)(1)(A) of the
Code, and that the transactions made the subject matter of the plan shall
constitute a "plan of reorganization" for purposes of the rules and regulations
governing Code Section 368.


                                  Article III.

                       REPRESENTATIONS AND WARRANTIES OF
                       GONZALES BANK AND GONZALES HOLDING

         Gonzales Bank and Gonzales Holding hereby make the following

Gonzales Bank, for the benefit of any of the present or former directors,
officers, or other employees of Gonzales Bank and Gonzales Holding.  Schedule
3.19(a) also identifies each "employee benefit plan," as such term is defined
in Section 3(3) of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA") maintained or contributed to by any member of the Gonzales
Consolidated Group.  Except as set forth in Schedule 3.19(a), all "employee
benefit plans" maintained by Gonzales Bank or Gonzales Holding (all such plans
being listed in Schedule 3.19(a) hereto) (collectively, the "Gonzales Bank
Plans") are in material compliance with the provisions of ERISA and the
applicable provisions of the Code.  No member of the Gonzales Consolidated
Group has ever maintained or become obligated to contribute to any "employee
benefit plan" as such term is defined in Section 3(3) of ERISA, (i) that is
subject to Title IV of ERISA or (ii) that is a multiemployer plan under Title
IV of ERISA.  To the knowledge of the Gonzales Consolidated Group, no
"prohibited transaction," as defined in Section 406 of ERISA or Section 4975 of
the Code, has occurred that could result in liability to Gonzales Holding,
Gonzales Bank or DGC, CNC or CNB. The Bank of Gonzales Savings Plan & Trust has
been determined to be "qualified" within the meaning of Section 401(a) of the
Code and neither Gonzales Bank nor Gonzales Holding knows of any fact which
would adversely affect the qualified status of such plan.  Gonzales Holding has
provided to DGC copies of the most recent determination letter issued by the
Internal Revenue Service with respect to such plan. No member of the Gonzales
Consolidated Group has any current or projected liability in respect of
post-employment welfare benefits for retired, current or former employees,
except as required to avoid excise tax under Section 4980B of the Code.

         (b)     except as may be necessary as advised in writing by  its
counsel to discharge its fiduciary duties, furnish any information relating to

or purchase of all or a substantial portion of the assets of, or of a
substantial equity interest in, Gonzales Holding or any subsidiary thereof, or
any business combination with Gonzales Holding or any subsidiary thereof, other
than as contemplated by this Agreement; and  shall instruct its officers,
directors, agents and affiliates to refrain from doing any of the above;
provided, however, that nothing contained herein shall be deemed to prohibit
any officer or director of Gonzales Holding from taking any action that counsel
to Gonzales Holding has advised in writing is required to discharge his or her
fiduciary duties to Gonzales Holding and its shareholders.

         Gonzales Bank and Gonzales Holding agree to notify DGC by telephone
within twenty-four hours of receipt of any inquiry with respect to a proposed
merger, consolidation, assets acquisition, tender offer or other takeover
transaction with another person or receipt of a request for information from
the FDIC, OCC or other governmental authority with respect to a proposed
acquisition of Gonzales Bank or Gonzales Holding by another party.

         5.03      Current Information.  During the period from the date of
this Agreement to the Effective Date, Gonzales Bank and Gonzales Holding will
cause one or more of its designated representatives to confer on a regular and
frequent basis with representatives of DGC and to report the general status of
its ongoing operations.  In addition, separate reporting on matters involving
the loan portfolio will occur monthly and will include, but not be limited to,
(i) all board reports, (ii) new and renewed loans (including loan
applications), (iii) delinquency reports, (iv) loan extensions, (v) to the
extent possible, loan policy exceptions, loan documentation exceptions, and
financial statement exceptions, (vi) watch list reports, (vii) all written
communications concerning problem loan accounts greater than $50,000, (viii)

the normal course of their business or in the operation of their properties and
of any governmental complaints, investigations or hearings (or communications
indicating that the same may be contemplated), or the institution or the threat
of litigation involving either party, and will keep DGC fully informed of such
events.

         5.04      Access to Properties and Records; Confidentiality.  (a) For
purposes of allowing DGC, CNC, and CNB and their counsel to prepare regulatory
submissions, and for other relevant purposes, Gonzales Bank and Gonzales
Holding shall permit DGC reasonable access to their properties during normal
business hours, and shall disclose and make available to DGC and its agents all
books, papers and records relating to their assets, stock ownership,
properties, operations, obligations and liabilities, including, but not limited
to: their books of account (including their general ledgers); tax records;
minute books of directors' and shareholders' meetings; charter documents;
bylaws; material contracts and agreements; filings with any regulatory
authority; litigation files; compensatory plans affecting its employees; and
any other materials pertaining to business activities, projects or programs in
which the other parties may have a reasonable interest in light of the proposed
Mergers.  No member of the Gonzales Consolidated Group shall be required to
provide access to or to disclose information where such access or disclosure
would violate or prejudice the rights of any customer or other person, would
jeopardize the attorney-client privilege of the institution in possession or
control of such information, or would contravene any law, rule, regulation,
order, judgment, decree or binding agreement.  The parties will make
appropriate substitute disclosure arrangements under circumstances in which the
restrictions of the preceding sentence apply.

         (b)     All information furnished by any member of the Gonzales
Consolidated Group pursuant hereto shall be treated as the sole property of the
party furnishing the information until consummation of the Mergers contemplated
hereby and, if such Mergers shall not occur, DGC, CNC, and CNB shall return to
Gonzales Holding  all documents or other materials containing, reflecting or
referring to such information, shall use its best efforts to keep confidential
all of such information, and shall not directly or indirectly use such
information for any competitive or other commercial purpose.  The obligation to
keep such information confidential shall continue for two (2) years from the
date the proposed Mergers are abandoned and shall not apply to (a) any
information which (i) DGC, CNC and CNB can establish by convincing evidence was
already in its possession prior to the disclosure thereof by Gonzales Holding
or Gonzales Bank, (ii) was then generally known to the public or set forth in
public records, (iii) became known to the public through no fault of DGC, CNC
or CNB, or (iv) was





                                       17
<PAGE>   94
disclosed to the party receiving the information by a third party not bound by
an obligation of confidentiality, or (b) disclosures in accordance with an
order of a court of competent jurisdiction.

         5.05      Interim Financial Statements.  As soon as reasonably
available, but in no event more than fifteen (15) days after the end of each
month ending after the date of this Agreement, Gonzales Bank and Gonzales
Holding will deliver to DGC copies of their monthly financial statements.

         5.06      Regulatory Matters.  (a) DGC shall prepare and file a
registration statement with the SEC on Form S-4 under the Securities Act (the
"Registration Statement"),  including a proxy statement (the "Proxy Statement")
to be mailed to Gonzales Holding shareholders in connection with the meeting to
be called to consider the Holding Company Merger, as soon as reasonably
practicable following the date of this Agreement.  The Registration Statement
shall comply in all material respects with the Securities Act and DGC will use
its best efforts to cause the Registration Statement to be declared effective
as soon as practicable, to qualify the DGC Common Stock under the securities or
blue sky laws of such jurisdictions as may be required and to keep the
Registration Statement and such qualifications current and in effect for so
long as is necessary to consummate the transactions contemplated hereby.

         (b)     DGC will use its best efforts to prepare all necessary
documentation, to effect all necessary filings and to obtain all necessary
permits, consents, approvals and authorizations of all third parties and
governmental bodies necessary to consummate the transactions contemplated by
this Agreement, including those required by the OCC, the Federal Reserve Board,
the FDIC and the Commissioner.

         (c)     Gonzales Holding shall cooperate in preparing the Registration
Statement and the Proxy Statement.  Gonzales Holding will promptly furnish all
such data and information relating to it and its subsidiaries as DGC may
reasonably request for the purpose of including such data and information in
the Registration Statement.

         (d)     DGC will indemnify and hold harmless Gonzales Holding, each of
its directors, each of its officers and each person, if any, who controls
Gonzales Holding within the meaning of the Securities Act against any losses,
claims, damages or liabilities, joint, several or solidary, to which they or
any of them may become subject, under the Securities Act, any state securities
or blue sky laws, or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
the Registration Statement, or in any amendment or supplement thereto, or the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse each such person for any legal or other expenses reasonably
incurred, promptly as they are incurred, by such person in connection with
investigating or defending any such action or claim; provided, however, that
DGC shall not be liable in any case to the extent that any such loss, claim,
damage or liability (or action in respect thereof) arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in the Registration Statement or any such amendment or supplement
in reliance upon or in conformity with information furnished to DGC by or on
behalf of the Gonzales Consolidated Group for use therein.

         (e)     Promptly after receipt by an indemnified party under
subparagraph (d) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against
DGC under such subparagraph, notify DGC in writing of the commencement thereof.
In case any such action shall be brought against any indemnified party and it
shall notify DGC of the commencement thereof, DGC shall be entitled to
participate therein and, to the extent that it shall wish, to assume the
defense thereof, with counsel satisfactory to such indemnified party, and,
after notice from DGC to such indemnified party of its election so to assume
the defense thereof, DGC shall not be liable to such indemnified party under
such subparagraph for any legal expenses of other counsel or any other expenses
subsequently incurred by such indemnified party; provided, however, if DGC
elects not to assume such defense or counsel for the indemnified parties
advises in writing that there are material substantive issues which raise
conflicts of interest between DGC or Gonzales Holding and one or more of the
indemnified parties, such indemnified parties may retain counsel satisfactory
to them, and DGC shall pay all reasonable fees and expenses of such counsel for
the indemnified parties promptly as statements therefor are received.

         filed as required; it being understood that such





                                       23
<PAGE>   100
         counsel need express no opinion as to the financial statements or
         other financial or statistical data contained in or omitted from the
         Registration Statement or the Proxy Statement; and

                 ix)      Such counsel has participated in several conferences
         with representatives of the parties of this Agreement and their
         respective accountants and counsel in connection with the preparation
         of the Registration Statement and the Proxy Statement to be filed in
         connection with the transactions contemplated by this Agreement and
         have considered the matters required to be stated therein and the
         statements contained therein, and based on the foregoing (in certain
         circumstances relying as to materiality on the opinions of officers
         and representatives of the parties to this Agreement) nothing has come
         to the attention of such counsel that would lead them to believe that
         such Registration Statement or the Proxy Statement, as amended or
         supplemented if it has been amended or supplemented, at the time it
         became effective and as amended or supplemented, (in the case of the
         Registration Statement) or at the time distributed to shareholders (in
         the case of the Proxy Statement), contained any untrue statement of a
         material fact or omitted a material fact required to be stated therein
         or necessary to make the statements therein not misleading (except in
         each such case for the financial statements and other financial and
         statistical data included therein, as to which no opinion need be
         rendered).

         As to matters of fact, counsel to DGC, CNC and CNB may rely, to the
extent they deem appropriate, upon certificates of officers of DGC, CNC, and
CNB, provided, such certificates are delivered to Gonzales Holding and Gonzales
Bank prior to the Closing or attached to the opinion of counsel.

         DGC, CNC, and CNB will furnish Gonzales Bank and Gonzales Holding with
such certificates of their officers or others and such other documents to
evidence fulfillment of the conditions set forth in this Section 6.03 as
Gonzales Bank and Gonzales Holding may reasonably request.

                                       24
<PAGE>   101
         (b)     by DGC,  CNC, and CNB, if at the time of such termination

condition of Gonzales Bank or Gonzales Holding from that set forth in Gonzales
Bank's or Gonzales Holding's Financial Statements for the period ended December

         (c)     by any party hereto, if a United States District Court shall

merits or a decision on the merits based on a stipulation of facts that the
transactions contemplated by this Agreement violate the antitrust laws of the
United States;

         (d)     by any party hereto, if at the special meeting of shareholders
to be called by Gonzales Holding pursuant to this Agreement, this Agreement

a majority of the outstanding shares of Gonzales Holding Common Stock voted at
the special meeting of shareholders of Gonzales Holding called pursuant to
Section 5.07 hereof;

         (e)     by DGC, CNC, and CNB, in the event there are dissenting

         (f)     by any party hereto if Closing shall not have occurred by

liability on the part of Gonzales Bank, Gonzales Holding, DGC,  CNC, CNB, or
their respective officers or directors.


                                  Article IX.

costs and expenses incurred in connection with the Mergers (including, but not
limited to, counsel fees) shall be paid by the party incurring such costs and
expenses.

         In recognition of the fact that DGC will bear the bulk of the expense
in preparing for regulatory approvals, in the event Gonzales Holding terminates
or seeks to terminate this Agreement without cause, or if the shareholders of
Gonzales Holding fail to approve the transaction because of action taken by an
officer or director of Gonzales Holding upon advice of counsel pursuant to
Section 5.02(b), Gonzales Holding shall indemnify DGC for all expenses
reasonably incurred by DGC in attempting to comply with the terms of the
Agreement.

                                                      May ___, 1996
Board of Directors
Bank of Gonzales Holding Company, Inc.
P.O. Box 1089
Gonzales, Louisiana 70707

Members of the Board:

We understand that Bank of Gonzales Holding Company, Inc., Gonzales, Louisiana
("Gonzales Holding") and Deposit Guaranty Corporation, Jackson, Mississippi
("DGC") have entered into an Agreement and Plan of Merger, dated as of February
5, 1996 (the "Agreement"), which provides, among other things, for the merger
(the "Merger") of Gonzales Holding with and into DGC.  Pursuant to the Merger,
each share of common stock, no par value, of Gonzales Holding (the "Gonzales
Holding Common Stock") issued and outstanding immediately prior to the
Effective Date other than shares of Gonzales Holding Company Common Stock owned
by stockholders who, pursuant to the Louisiana Business Corporation Law
("LBCL"), perfect dissenters' rights ("Dissenting Shares"), shall, by virtue of
the Agreement and without any action on the part of the holder thereof, be
converted into and exchangeable for the number of shares of common stock, no
par value, of DGC (the "DCG Common Stock") equal to the Exchange Ratio, as
defined below, subject to adjustment as provided herein and, in respect of
fractional shares, subject to Section 1.06 of the Agreement.

The Exchange Ratio shall equal 634,000 divided by the number of shares of
Gonzales Holding Common Stock outstanding on the date immediately preceding the
Effective Date.  If prior to the Effective Date DGC should split or combine DGC
Common Stock, or pay a dividend or other distribution in DGC Common Stock, then
the exchange ratio shall be appropriately adjusted to reflect such split,
combination, dividend or distribution.  The terms and conditions of the Merger
are more fully set forth in the Agreement.  Based upon 541,611 of Gonzales
Holding Common Stock outstanding and a stock price of $46.75 per share as of
March 22, 1996 for DGC's Common Stock, DGC will issue 634,000 common shares to
Gonzales Holding shareholders for a total transaction value of $29,639,500.

You have requested our opinion, as an independent financial advisor, as to
whether the Agreement is fair from a financial point of view to holders of
Gonzales Holding Common Stock, as of the date hereof.

In connection with our opinion, we have: (i) reviewed the Agreement; (ii)
reviewed certain publicly available financial statements and other information
of Gonzales Holding and DGC; (iii) reviewed certain internal financial
statements and other financial and operating data concerning Gonzales Holding
and DGC; (iv) discussed the past and current operations and financial condition
and the prospects of Gonzales Holding and DGC with senior executives; (v)
reviewed certain historical market prices and trading volumes of DGC and
compared them to other publicly traded companies deemed relevant; (vi) compared
Gonzales Holding and DGC from a financial point of view with certain other
companies which we deemed to be relevant; (vii) reviewed the results of certain
regulatory examinations of Gonzales Holding and DGC with the senior management
of the respective companies; (viii) reviewed the financial terms, to the extent
publicly available, of certain comparable merger transactions; and (ix)
performed such other analyses and examinations as we have deemed appropriate.
<PAGE>   108
We have assumed and relied upon without independent verification the accuracy
and completeness of the information reviewed by us for the purposes of this
opinion.  In addition, we have not made an independent evaluation of the assets
or liabilities of Gonzales Holding and DGC, nor have we been furnished with any
such appraisals.  In addition, we are not an expert in the evaluation of loan
portfolios for the purposes of assessing the adequacy of the allowance for
losses with respect thereto and have assumed that such allowances for each of
the companies are in the aggregate adequate to cover such losses.  Our opinion
is necessarily based on economic, market and other conditions as in effect on,
and the information made available to us as of, the date hereof.  With respect
to financial forecasts, as well as projected cost savings, we have assumed that
they have been reasonably prepared and reflect the best currently available
estimates and judgments of management of Gonzales Holding and DGC, as to the
future financial performance of Gonzales Holding and DGC, respectively, and we
have assumed such forecasts and projections will be realized in the amounts and
at the times contemplated thereby.

Our opinion is limited to the fairness, from a financial point of view, to the
holders of Gonzales Holding Common Stock of the Agreement and does not address
Gonzales Holding's underlying business decision to undertake the Merger.
Moreover, this letter, and the opinion expressed herein, does not constitute a
recommendation to any stockholder as to any approval of the Merger or the
Agreement.  It is understood that this letter may not be disclosed or otherwise
referred to without our prior written consent, except as may otherwise be
required by law or by a court of competent jurisdiction.

                                        Very truly yours,


                                        ALEX SHESHUNOFF & CO.

                                   EXHIBIT C

                     SECTION 131 OF THE LOUISIANA BUSINESS
                                CORPORATION LAW
<PAGE>   110
                                   EXHIBIT C



                             La. R.S. 12:131 (1993)

Section  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 percent 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 be taken by the required vote, but by less than
eighty percent 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 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
<PAGE>   111
limited, he shall conclusively be presumed to have acquiesced in the corporate
action proposed or 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
judgment 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 judgment against the
corporation for the fair cash value of his shares. No order or decree shall be
made by the court staying the proposed corporate 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 the 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 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.
<PAGE>   112
         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.

                PART II.  INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Deposit Guaranty is incorporated under the laws of Mississippi.
Subarticle E of Article 8 of the Mississippi Business Corporation Act
prescribes the conditions under which indemnification may be obtained by a
present or former director or officer of Deposit Guaranty who incurs expenses
or liability as a consequence of matters arising out of his activities as a
director or officer.

         Article Nine of Deposit Guaranty's Articles of Incorporation also
provides for indemnification of officers and directors under certain
circumstances. Deposit Guaranty has purchased a liability policy which, subject
to any limitations set forth in the policy, indemnifies Deposit Guaranty's
directors and officers for damages that they become legally obligated to pay as
a result of any negligent act, error or omission committed by such person in
his capacity as an officer or director.

ITEM 22.  UNDERTAKINGS

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

         (2) The Registrant hereby undertakes that every prospectus (i) that is
filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to
meet the requirements of section 10(a)(3) of the Act and issued in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

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

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

         (5) The Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the Registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 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.

         (6) Insofar as indemnification for liabilities arising under the Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 20 above, 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.

634,000 shares of Common Stock, no par value, under the Securities Act of 1933.

         RE:   THE FEDERAL INCOME TAX CONSEQUENCES OF CERTAIN MATTERS ARISING
               UNDER THE CORPORATE REORGANIZATION PROVISIONS OF THE INTERNAL
               REVENUE CODE OF 1986, AS AMENDED

Gentlemen:

         You have requested our opinion regarding the federal income tax
consequences of the proposed merger of Bank of Gonzales Holding Company, Inc.
("Gonzales Holding") with and into Commercial National Corporation ("CNC"),
immediately followed by the merger of Bank of Gonzales with and into Citizens
National Bank ("CNB").  The merger of Gonzales Holding with and into CNC is
hereinafter referred to as the "Holding Company Merger."  The merger of Bank of
Gonzales with and into CNB is hereinafter referred to as the "Bank Merger."
Both mergers are
<PAGE>   2
sometimes hereinafter collectively referred to as the "Mergers," and each
merger is more fully described herein.  Unless otherwise noted, the capitalized
terms herein shall have the same meaning ascribed to such terms in that certain
Agreement and Plan of Merger by and among you, dated as of February 5, 1996
(the "Merger Agreement").  This opinion is rendered in satisfaction of the
closing condition described in Section 6.01(c) of the Merger Agreement.

         We have examined and are familiar with the Merger Agreement, the Proxy
Statement/Prospectus of DGC and Gonzales Holding dated May __, 1996 regarding
the proposed transactions, certain financial statements of the parties to the
proposed Mergers, and such other documents as we have deemed sufficient to
enable us to express our informed opinion.  In rendering this opinion we have
relied not only on such documents but also on the representations and
statements of the parties to the proposed Mergers, some of which are stated in
the Certificate dated ___, 1996, attached hereto as Exhibit "A", regarding
certain matters addressed in this opinion, and the following factual
information supplied by the parties to the proposed Mergers.

               I.  BACKGROUND FACTS CONCERNING CORPORATE PARTIES

A.       Deposit Guaranty Corp.

         Deposit Guaranty Corp. ("DGC") was incorporated in 1968 under the laws
of the State of Mississippi for the primary purpose of acting as a bank holding
company for Deposit Guaranty National Bank ("DGNB"), a national banking
association.  DGC is registered as a bank holding company with the Federal
Reserve System.

         DGC has an authorized capital structure consisting of 100,000,000
shares of no par value voting common stock ( the "DGC Common Stock"),
25,000,000 shares of no par value Class A voting preferred stock,  and
25,000,000 shares of Class B non-voting preferred stock.  As of December 31,
1995, DGC had 19,379,643 shares of Common Stock issued and outstanding and no
preferred stock is outstanding.  DGC is a publicly held company with over 6,000
shareholders of record as of December 31, 1995, and its stock is traded on the
NASDAQ National Market System.  In addition, as of December 31, 1995, options

         DGC and its subsidiaries are engaged only in the general banking
business and activities closely related to banking, as authorized by the
banking laws of the United States and the regulations issued pursuant thereto.

         The books of account of DGC are maintained on a calendar year basis
and DGC computes its income under the accrual method of accounting.  DGC is the
parent of an affiliated group that, for federal income tax purposes, includes,
among other entities, CNC (described below), and CNB.

B.       Commercial National Corporation

         CNC is a bank holding company and is registered as such with the
Federal Reserve System.  The authorized capital stock of CNC consists of
5,000,000 shares of common stock, $5.00 par value.
<PAGE>   3
There are 4,200,000 shares of CNC common stock issued and outstanding, all of
which are owned by DGC.  All of CNC's common stock was acquired by DGC in
February, 1990.

         CNC does not engage in any business activities other than its
ownership of CNB and Commercial National Bank.  The books of CNC are maintained
on a calendar year basis and CNC computes its income under the accrual method
of accounting.

C.       Citizens National Bank

         CNB is a national banking association, duly organized and validly
existing under the laws of the United States with its main office located in
Hammond, Louisiana.  All of its branches are located in the State of Louisiana.
CNB conducts a general banking business embracing all of the customary banking
functions as are permitted by Federal regulatory authorities.

         Presently, CNB has authorized capital stock consisting of 234,121
shares of Common Stock (the "CNB Common Stock").  All of the CNB Common Stock
is outstanding and is owned by CNC.

         CNB's books of account are maintained on a calendar year, accrual
basis and it files a consolidated federal income tax return with CNC and DGC.

D.       Gonzales Holding.

         Gonzales Holding was organized under the laws of the State of
Louisiana for the purpose of acting as a bank holding company.  Gonzales
Holding offers a full complement of consumer and commercial banking services
through its only subsidiary, Bank of Gonzales.  Gonzales Holding is registered
as a bank holding company with the Federal Reserve System.

         Gonzales Holding has an authorized capital structure consisting of
10,000,000 shares of Common Stock (the "Gonzales Holding Common Stock").  There
are 561,801 shares of Gonzales Holding Common Stock issued and outstanding to
756 stockholders of record.  The Gonzales Holding Common Stock is not traded on
an established securities market.


         Gonzales Holding's books of account are maintained on a calendar year
basis and Gonzales Holding computes its income under the accrual method of
accounting.

E.       Bank of Gonzales.

validly existing under the laws of the state of Louisiana with its principal
office located in Gonzales, Louisiana.   The authorized capital structure of
Bank of Gonzales consists of 440,000 shares of Common Stock (the "Bank of
Gonzales Common Stock"), all of which are outstanding and owned by Gonzales
Holding.

         Bank of Gonzales offers a wide range of consumer and commercial
banking services in the Ascension Parish, Louisiana area.  Bank of Gonzales's
books of account are maintained on a calendar year basis.  It files a
consolidated federal income tax return with Gonzales Holding.


                   II.  BUSINESS REASONS FOR AND  DESCRIPTION
                            OF THE PROPOSED MERGERS

A.       Gonzales Holding's Reasons for the Mergers.

         In reaching its decision that the Merger Agreement is in the best
interests of Gonzales Holding and its shareholders, the Board of Gonzales
Holding considered a number of factors in addition to the financial terms,
including, but not limited to the following: (a)  the financial condition and
results of operations of, and prospects for, each of Gonzales Holding and DGC;
(b) the likelihood that Gonzales Bank would experience significant increased
competitive pressures in its market area from larger banking and other
financial institutions capable of offering a broader array of technologically
advanced financial services and products; (c) the lack of marketability of
Gonzales Holding Common Stock and the liquidity that would be offered to
Gonzales Holding's shareholders through the ownership of securities of a
publicly traded company such as DGC;  (d)  the financial terms of the Mergers,
including the relationship of the value of the DGC Common Stock issuable in the
Mergers to the market value, book value, and earnings per share of Gonzales
Holding Common Stock; (e) the nonfinancial terms of the Mergers, including the
treatment of the Mergers as a tax-free exchange of Gonzales Holding Common
Stock for DGC Common Stock for federal and state income tax purposes; (f) the
likelihood of the Mergers being approved by applicable regulatory authorities
without undue conditions or delay; and(g) the opinion rendered by Sheshunoff,
Gonzales Holding's financial advisor, to the effect that the terms of the
Mergers, as provided in the Merger Agreement, are fair from a financial point
of view, to the holders of Gonzales Holding Common Stock.


B.       DGC's Reasons for the Mergers.

         The DGC Board of Directors believes that by expanding DGC's customer
base into the southern portion of Louisiana, the Mergers should enhance DGC's
earnings capacity by enabling it to deliver products and provide services to
that enlarged customer base, and by permitting cost savings through
consolidation of operations.  In addition, the DGC Board of Directors believes
that the combination of DGC and Gonzales Holding will allow DGC and Gonzales
Holding to increase overall efficiency and take advantage of economies of scale
in several areas.  In evaluating the Mergers, the DGC Board of Directors
considered a variety of factors, including the respective results of
operations, financial condition and prospects of DGC and Gonzales Holding; the
compatibility and complimentary nature of the respective businesses and
managerial philosophies of DGC and Gonzales Holding; and the relative prices
paid in recent acquisitions of financial institutions.

C.       Description of Proposed Mergers.

         The proposed Mergers will be structured in accordance with the
preceding statements of background facts, the Merger Agreement, the laws of the
State of Louisiana and the United States, the representations of the parties to
the transactions, and the following descriptions:

         1.    The Holding Company Merger.  Pursuant to the Merger Agreement,
               Gonzales Holding will merge with and into CNC pursuant to the
               laws of the State of Louisiana.  CNC will be the surviving
               corporation.  On the Effective Date of the Holding Company
               Merger, each share of Gonzales Holding Common Stock issued and
               outstanding (other than shares owned by shareholders who,
               pursuant to the Louisiana Business Corporation Law, perfect any
               right to receive the fair value of such shares ("Dissenting
               Shares")), will be converted into and exchangeable for a number
               of shares of DGC Common Stock determined by dividing 634,000 by
               the number of shares of Gonzales Holding Common Stock
               outstanding on the date immediately preceding the Effective Date
               (the "Exchange Ratio").

               Any dissenters to the Holding Company Merger who meet the
               statutory requirements,  will have the right under Louisiana law
               to receive cash for their shares from Gonzales Holding.  The
               Merger Agreement, however, provides that Deposit Guaranty may
               terminate the Merger Agreement if more than ten percent (10%) of
               the Gonzales Holding Common Stock outstanding at the Effective
               Date of the Holding Company Merger would be converted into cash.

         2.    The Bank Merger.  Immediately after the Holding Company Merger,
               Bank of Gonzales will merge with and into CNB in accordance with
               applicable federal and state law.  CNB will acquire all of the
               assets and assume all of the liabilities of Bank of Gonzales,
               and Bank of Gonzales will cease to exist.  Each share of
               outstanding Bank of Gonzales Common Stock will be canceled.  CNC
               will constructively receive CNB Common Stock as consideration
               for the Bank Merger.  No new shares of CNB Common Stock will
               actually be issued to CNC or to Bank of Gonzales in the Bank
               Merger.  There will be no dissenters to the Bank Merger.

         3.    Fractional Shares.   No fractional shares of DGC Common Stock
               will be issued in the Mergers.  Any shareholder otherwise
               entitled to receive a fractional share of DGC Common Stock will
               be paid a cash amount in lieu of any such fractional share
               determined by multiplying (i) the closing sale price of a share
               of DGC Common Stock on the date immediately proceeding the
               Effective Date as quoted on the National Association of
               Securities Dealers Automated Quotation System, by (ii) the
               fraction of a share of DGC Common Stock to which such holder
               would otherwise be entitled.

         4.    Effects of the Mergers.  After the Mergers are completed, all of
               Gonzales Holding's former shareholders will own DGC Common
               Stock.  There will be no cash paid in connection with either of
               the Mergers (except for payments for fractional shares as
<PAGE>   6
               noted above).  The ownership structure of DGC, CNC, and CNB will
               not change.  After the Holding Company Merger, CNC will continue
               both its and Gonzales Holding's historical business in a
               substantially unchanged manner.  After the Bank  Merger, CNB
               will continue both its and Bank of Gonzales' historical business
               in a substantially unchanged manner.

            III.  DISCUSSION OF APPLICABLE REORGANIZATION PROVISIONS

A.       The Holding Company Merger.

The parties intend that the Holding Company Merger will satisfy the
requirements for nonrecognition (i.e., treatment as a tax-free reorganization)
under section 368(a)(1)(A) of the Internal Revenue Code of 1986, as amended
(the "Code") by reason of the application of Code section1/ 368(a)(2)(D).
These Code sections describe a forward triangular or subsidiary merger under
which the target corporation (Gonzales Holding) is merged into a first tier
subsidiary (CNC) of the parent corporation (DGC here) in exchange for parent
company stock distributed to the target's historic shareholders.

         Following are the criteria for nonrecognition in the case of a forward
triangular merger (applied in the context of the proposed Holding Company
Merger):

         1.  "Substantially all" of the properties of Gonzales Holding must be
acquired by CNC.  For Internal  Revenue Service ("Service") ruling purposes,
this means that CNC must acquire at least seventy percent (70%) of the fair
market value of the gross assets and at least ninety percent (90%) of the fair
market value of the net assets held by Gonzales Holding immediately prior to
the Holding Company Merger.  See Code section 368(a)(2)(D); Treas. Reg. Section
1.368- 2(b)(2); and Rev. Proc. 77-37, 1977-2 C.B. 568, Section 3.01.

         2.  A "could have merged with the parent" test must be met.  This test
means that it must have been possible for Gonzales Holding to have merged
directly into DGC in a transaction  qualifying under Code section 368(a)(1)(A)
(a "Type A" merger).  A Type A merger is a statutory merger under state or
federal law (although Code section 368(a)(1)(A) also covers consolidations,
consolidations are not permitted in the context of Code section 368(a)(2)(D)).
This test essentially means that it must be shown that the continuity of
interest, business purpose and continuity of business enterprise requirements
would have been met had Gonzales Holding merged into DGC.  See Treas. Reg.
Section 1.368- 2(b)(2).

         3.  The stock issued in consideration of CNC's acquisition of Gonzales
Holding's properties must consist solely of parent (DGC) stock.  The use of any
CNC stock would disqualify the Holding Company Merger under Code section
368(a)(2)(D).

         4.  In addition to the requirements under the Code which have been
generally described above, nonrecognition for the Holding Company Merger is
subject to several other nonstatutory rules that have been established through
case law and Treasury Regulations.  These requirements involve continuity of
proprietary interest, continuity of business enterprise, and the existence of a
valid business purpose for the transaction.  The judicially-developed step
transaction doctrine,





____________________

1/ Unless otherwise noted, all section references are to the Code.
<PAGE>   8
wherein a series of formally separate steps are considered together as
component parts of an overall plan, must also be considered when evaluating
whether a transaction, in substance, qualifies as a valid forward subsidiary
merger under Code section 368(a)(1)(A) and section 368(a)(2)(D).

         B.    The Bank Merger.

         The Bank Merger will be a statutory merger of downstream
brother-sister corporations.  As such, the Bank Merger will qualify, for
federal income tax purposes, as a tax-free reorganization under section
368(a)(1)(A) (a "Type A reorganization").

         The Bank Merger is also described in and will qualify as a tax-free
reorganization under section 368(a)(1)(D) (a "Type D reorganization").  The
Code describes a Type D reorganization involving the transfer of assets to a
controlled corporation, as follows:

         1.    A transfer by one corporation of substantially all of its assets
               to a controlled corporation (i.e., a corporation owned by the
               transferor or its shareholders2/, followed by a section 354 or
               section 356 of the distribution of the stock, and

         2.    In effect, a complete liquidation of the transferor corporation.
               (Although section 354(b) does not explicitly require a complete
               liquidation of the transferor, the requisite distribution of all
               of the transferor's properties will have the effect of a
               complete liquidation).

         The Service has ruled that in cases involving an overlap of a Type A
and a Type D reorganization, the Type D reorganization controls.  See Rev. Rul
75-161, 1975-1 C.B. 114.  The difference is that Rev. Rul. 75-161 provides that
section 357(c) applies to the transaction.  Section 357(c) requires that if the
sum of the amount of the liabilities assumed by the corporate transferee and
the amount of the liabilities to which the property transferred is subject
exceeds the total of the adjusted basis of the property transferred, then the
excess shall be recognized as gain by the transferor.  As stated in the
Certificate, in connection with the Bank Merger, Bank of Gonzales has
represented that the liabilities of Bank of Gonzales which will be assumed by
CNB,  plus the amount of the liabilities to which the property transferred is
subject, will not exceed Bank of Gonzales's total adjusted basis in the
property transferred.  Based on this representation and our limited review of
pertinent financial statements, we have concluded that the gain recognition
provision of section 357(c) should not apply to the Bank Merger.

                                  IV. OPINION

         In reliance upon the foregoing facts and the representations of the
parties to the Merger transactions, and based upon our review of such documents
and consideration of such legal matters as

2/ The determination of whether a "controlled corporation" exists is made 
   using the 50% ownership test of section 304(c) as the "control" threshold, 
   as mandated by section 368(a)(2)(H).
<PAGE>   9
we have deemed relevant and sufficient to enable us to render an informed
opinion, we are of the opinion that the federal income tax consequences of the
proposed Mergers will be as follows:

A.       With respect to the Holding Company Merger:

         1.    Provided the proposed Merger of Gonzales Holding with and into
               CNC qualifies as a statutory merger under applicable Louisiana
               law, the acquisition by CNC of substantially all of the assets
               of Gonzales Holding in exchange for shares of DGC Common Stock
               and the ssumption of liabilities of Gonzales Holding will
               constitute a reorganization within the meaning of Code section
               368(a)(1)(A) and section 368(a)(2)(D).

               For purposes of this opinion, "substantially all" means at least
               90 percent of the fair market value of the net assets and at
               least 70 percent of the fair market value of the gross assets of
               Gonzales Holding held immediately prior to the Merger.  DGC,
               CNC, and Gonzales Holding will each be "a party to a
               reorganization" within the meaning of section 368(b) of the
               Code.

         2.    No gain or loss will be recognized by Gonzales Holding upon the
               transfer of substantially all of it assets to CNC in exchange
               solely for DGC Common Stock and the assumption by CNC of the
               liabilities of Gonzales Holding (Code sections 361(a) and
               357(a)).   Such non-recognition is not affected by the fact that
               Gonzales Holding will be deemed to receive cash in lieu of
               fractional share interests of Gonzales Holding shareholders,
               since all of the cash will be deemed distributed to Gonzales
               Holding shareholders pursuant to the Merger Agreement.

         3.    No gain or loss will be recognized to Gonzales Holding upon the
               transfer of substantially all of it assets to DGC in exchange
               solely for DGC Common Stock and the assumption by DGC of the
               liabilities of Gonzales Holding.  (Rev. Rul. 57-278, 1957-1 C.B.
               124).

         4.    No gain or loss will be recognized by DGC upon the receipt by
               CNC of substantially all of the assets of Gonzales Holding
               solely in exchange for DGC Common Stock issued to Gonzales
               Holding and the assumption by CNC of the liabilities of Gonzales
               Holding and the liabilities to which the transferred assets are
               subject (Rev. Rul 57-278, 1957-1 C.B. 124).


         5.    The basis of the assets of Gonzales Holding in the hands of DGC

               in the hands of Gonzales Holding immediately prior to the
               Holding Company Merger (Code section 362(b)).

         6.    The holding period of Gonzales Holding's assets in the hands of
               DGC will include the period during which the assets were held by

               entitled) solely in exchange for their Gonzales Holding Common
               Stock (Code section 354(a)(1)).

         8.    The basis of the DGC Common Stock to be received by the Gonzales

               to which they may be entitled) will be, in each instance, the
               same as the basis of the Gonzales Holding Common Stock
               surrendered in exchange therefor (Code section 358)).

         9.    The holding period of the DGC Common Stock to be received by

               of fractional shares of DGC Common Stock will be treated for

               been received as distributions in redemption of such stock,

               the Code.

               solely cash in exchange for his or her Gonzales Holding Common
               Stock, such cash will be treated as having been received by
               the shareholder as a distribution in redemption of his or her
               stock subject to the provisions and limitations of section
               302.

B.       With respect to the Bank Merger:

         1.    Provided that the merger of Bank of Gonzales into CNB
               qualifies as a statutory merger under applicable state or

               within the meaning of section 368(a)(1)(A) of the Code.  Bank
               of Gonzales and CNB will each be "a party" to a

               transfer of all of its assets to CNB in constructive exchange
               for CNB Common Stock issued to CNC and the assumption by CNB
               of the liabilities of Bank of Gonzales (Code sections 361(a)
               and 357(a)).

               CNB of all of the assets of Bank of Gonzales in constructive

               to CNC and the assumption by CNB of the liabilities of Bank of

               are subject (Rev. Rul 57-278, 1957-1 C.B. 124).
               
         4.    No gain or loss will be recognized by DGC or CNC as a result
               of the Bank Merger and the surrender of the Bank of Gonzales
               Common Stock in constructive exchange for the CNB Common
               Stock.
               
         5.    The basis of the assets of Bank of Gonzales in the hands of
               CNB will, in each case, be the same as the basis of those
               assets in the hands of Bank of Gonzales immediately prior to
