                          AGREEMENT AND PLAN OF MERGER


         THIS AGREEMENT AND PLAN OF MERGER  ("Agreement")  is made September 28,
1995, between Whitney Holding Corporation ("Whitney"),  a Louisiana corporation,
Whitney Acquisition Corporation  ("Acquisition"),  a Louisiana corporation,  and
Whitney National Bank ("Whitney's Bank"), a national banking association, on the
one  hand,  and  First  Citizens  BancStock,  Inc.  ("Citizens"),   a  Louisiana
corporation,  and First  National Bank in St. Mary Parish  ("Bank"),  a national
banking association, on the other hand. Whitney,  Acquisition and Citizens shall
be hereinafter collectively referred to as the "Constituent Corporations".

                                    Preamble

         The boards of  directors  of Whitney,  Acquisition  and  Citizens  have
determined  that it is desirable and in the best  interests of their  respective
corporations and shareholders that Citizens merge into Acquisition (the "Company
Merger").  The  boards of  directors  of  Whitney's  Bank and the Bank have each
determined  that  it is  desirable  and in  the  best  interests  of  each  such
institution  and its sole  shareholder  that the Bank merge into  Whitney's Bank
(the "Bank Merger"). The Company Merger and the Bank Merger shall be hereinafter
collectively referred to as the "Mergers".

         NOW THEREFORE,  in  consideration of the  representations,  warranties,
covenants and agreements herein contained, the parties hereto agree as follows:

         Section 1.  The Mergers and Closing

         1.01.  Mergers.

                  (a) Promptly after execution of this Agreement,  the Boards of
Directors of Acquisition and Citizens will execute the merger agreement  annexed
hereto as Exhibit 1.01(a) (the "Company Merger  Agreement"),  pursuant to which,
on the terms set forth herein and subject to the conditions set forth in Section
6 hereof,  Citizens  will merge with and into  Acquisition,  which  shall be the
surviving corporation.

                  (b) Promptly after the execution of this Agreement, the Boards
of Directors of  Whitney's  Bank and the Bank will execute the merger  agreement
annexed  hereto as Exhibit  1.01(b) (the "Bank Merger  Agreement"),  pursuant to
which,  on the terms set forth herein and subject to the conditions set forth in
Section 6 hereof,  Bank will merge with and into Whitney's Bank,  which shall be
the surviving bank. The Company Merger  Agreement and the Bank Merger  Agreement
shall be hereinafter collectively referred to as the "Merger Agreements".

                  (c) Effects of  Mergers.  The  Company  Merger  shall have the
effects set forth in the Louisiana  Business  Corporation Law ("LBCL").  Without
limiting the generality of the foregoing,  and subject thereto, at the Effective
Time, all the property and assets, rights, privileges and all debts, liabilities
and obligations of Citizens will become the assets, rights,  privileges,  debts,
liabilities and  obligations of Acquisition as the surviving  corporation in the
Company Merger. The Bank Merger shall have the effects set forth in the National
Banking



                                Page 24 of 63

Laws. Without limiting the generality of the foregoing,  and subject thereto, at
the Effective  Time,  all the property and assets,  rights,  privileges  and all
debts,  liabilities  and  obligations  of Bank will become the  assets,  rights,
privileges,  debts,  liabilities  and  obligations  of  Whitney's  Bank  as  the
surviving association in the Bank Merger.

         1.02.  The  Closing.  The  "Closing" of the  transactions  contemplated
hereby will take place in the Board Room of  Whitney,  228 St.  Charles  Avenue,
Second  Floor,  New Orleans,  Louisiana  70130 (or such other place to which the
parties may agree),  at 10:00 a.m.,  New Orleans Time,  on a mutually  agreeable
date as soon as practicable  following  satisfaction of the conditions set forth
in subparagraphs  (a), (b) and (d) of subsection 6.01 hereof,  or if no date has
been  agreed to, on any date  specified  by any party to the others upon 10 days
notice following satisfaction of such conditions.  The date on which the Closing
occurs is herein  called the  "Closing  Date".  If all  conditions  set forth in
Section 6 hereof are  satisfied  or waived by the party  entitled  to grant such
waiver,  at the Closing (a) the Constituent  Corporations  shall each provide to
the other such proof of satisfaction of the conditions set forth in Section 6 as
the  party  whose   obligations  are  conditioned  upon  such  satisfaction  may
reasonably  request,  (b) the  certificates,  letters and  opinions  required by
Section 6 shall be delivered,  (c) the appropriate officers of the parties shall
execute, deliver and acknowledge the Merger Agreements and (d) the parties shall
take  such  further  action  as  is  required  to  consummate  the  transactions
contemplated  by  this  Agreement  and the  Merger  Agreements.  If on any  date
established  for the  Closing all  conditions  in Section 6 hereof have not been
satisfied or waived by the party entitled to grant such waiver,  then any party,
on one or more  occasions,  may declare a delay of the Closing of such duration,
not exceeding 10 business days, as the declaring party shall select, but no such
delay shall extend beyond the date set forth in  subparagraph  (c) of subsection
7.01, and no such delay shall interfere with the right of any party to terminate
this Agreement pursuant to Section 7.

         1.03.   The  Effective  Date  and  Time.   Immediately   following  (or
concurrently  with) the Closing,  the Merger  Agreements shall be filed with and
recorded  by  the  Secretary  of  State  of  Louisiana  and  the  Office  of the
Comptroller of the Currency, as appropriate,  and the Mergers shall be effective
at the date and time specified in the Merger  Agreements.  The date on which and
the time at which the Company Merger becomes effective are herein referred to as
the "Effective Date" and the "Effective Time," respectively.

         1.04.  Surviving  Corporations.   The  governing  documents  (i.e.  the
articles of  incorporation  and  by-laws and  equivalents)  of  Acquisition  and
Whitney's  Bank in  effect  immediately  prior to the  Effective  Time,  and the
directors and officers of Acquisition  and Whitney's Bank in office  immediately
prior to the Effective Time, shall be the governing  documents and directors and
officers of  Acquisition  and Whitney's  Bank, as the surviving  entities in the
Mergers,  after the Effective  Time,  until duly amended in accordance  with the
terms thereof and  applicable  law. Such  directors and officers  shall serve in
such capacity in accordance  with the articles of  incorporation  and by-laws of
the  surviving  entities.  Each  share of  Whitney  common  stock,  no par value
("Whitney  Common  Stock") and capital stock of  Acquisition  and Whitney's Bank
issued and  outstanding  immediately  prior to the  Effective  Time shall remain
issued and outstanding from and after the Effective Time, and in the case of

                                        2

                                 Page 25 of 63

Acquisition  and Whitney's  Bank,  shall be the capital stock of the  respective
surviving entity in the Mergers.

         1.05. Tax Consequences.  It is the intention of the parties hereto that
the Mergers  shall  constitute  a  reorganization  within the meaning of Section
368(a) of the Internal  Revenue Code of 1986, as amended (the "Code"),  and that
this  Agreement  shall  constitute  a "plan of  reorganization"  for purposes of
Section 368 of the Code.

         Section 2.  Conversion of Stock of Citizens

         2.01.  Conversion.  Subject to the provisions of this Section 2, at the
Effective  Time,  by virtue of the Company  Merger and without any action on the
part of the holders  thereof,  the shares of Citizens  common  stock,  par value
$1.00 per share ("Citizens Common Stock"), shall be converted as follows:

                  (a)  Exchange   Ratio.   Except  for  (i)  shares  issued  and
outstanding  immediately  prior to the  Effective  Time as to which  dissenters'
rights have been  perfected  and not  withdrawn  or  otherwise  forfeited  under
Section  131 of the LBCL  ("Dissenters'  Shares")  and (ii)  shares of  Citizens
Common Stock held by Citizens as treasury  shares  (which shall by reason of the
Company Merger be cancelled),  and subject to the provisions of Section  2.01(c)
relating to fractional  shares,  each issued and  outstanding  share of Citizens
Common Stock shall be converted into and become that number of shares of Whitney
Common Stock that is equal to the quotient (the  "Exchange  Ratio")  obtained by
dividing the Maximum  Deliverable  Amount (as hereinafter  defined) by the total
number of issued and outstanding shares (not treasury shares) of Citizens Common
Stock at the Effective Time.

                           (i)  Maximum  Deliverable  Amount.  The term "Maximum
Deliverable Amount" means the quotient  obtained by dividing the Closing  Amount
(as defined below) by the Average Market Price (as defined below).

                           (ii)  Average  Market  Price.   The  "Average  Market
Price" shall be the average of the closing per share trading prices  of  Whitney
Common  Stock  (adjusted  appropriately  for  any  stock  split, stock dividend,
recapitalization,  reclassification or similar transaction which is effected, or
for which a record date  occurs) on the twenty (20) trading days  preceding  the
fifth  trading  day immediately  prior to the Effective Time, as reported in the
Wall Street Journal  (corrected for typographical  errors);  provided,  however,
that if the Average  Market Price as calculated  above is less than $25.50,  the
Average Market Price for purposes of this Section  2.01(a) shall be $25.50,  and
if the Average  Market  Price as  calculated  above is greater than $35.50,  the
Average Market Price for purposes of this Section 2.01(a) shall be $35.50.

                           (iii)  Closing  Amount.   The  term  "Closing Amount"
means the Aggregate Purchase Price (as defined below) minus the number of shares
of Citizens  Common Stock under option  at  the  Effective  Time  (the  "Closing
Option  Shares") multiplied by the  difference of the quotient of the  Aggregate
Purchase Price plus the Closing Option Shares multiplied by the

                                       3

                                Page 26 of 63

<PAGE>



weighted  average strike price per share of the Closing Option Shares divided by
the number of shares of  Citizens Common Stock outstanding at the Effective Time
plus the Closing Option  Shares  and the weighted average strike price per share
of the Closing Option Shares.  The Closing Amount is further defined below:

                           The  Closing  Amount  =  Aggregate  Purchase  Price -
(Closing Option Shares  *  (((Aggregate Purchase Price + Closing Option Shares *
Average  Option  Strike  Price  Per  Share)/(Citizens Common Stock Outstanding +
Closing Option Shares)) - Average Option Strike Price Per Share))

(iv) Aggregate Purchase Price. The term "Aggregate Purchase Price" is defined as
$67,000,000  if the  Average  Market  Price is $25.50 or above.  If the  Average
Market Price drops below $25.50,  the Aggregate  Purchase Price will be equal to
the Average Market Price multiplied by 2,627,451. In no event shall the value of
the  shares  of  Whitney  Common  Stock  to be  issued  at  the  Closing  exceed
$67,000,000.

                  (b)  Options.  Each option  under  Citizens'  Option Plans (as
hereinafter  defined)  that  is  outstanding  at the  Effective  Time  shall  be
converted into an option to acquire shares of Whitney Common Stock in the manner
set forth in Section 5.22 of this Agreement.

                  (c) Fractional  Shares.  In lieu of the issuance of fractional
shares of Whitney Common Stock, each shareholder of Citizens,  upon surrender of
his or her certificate that immediately  prior to the Effective Time represented
Citizens  Common  Stock,  other than  Dissenters'  Shares and shares of Citizens
Common Stock held by Citizens as treasury  shares  (which shall by reason of the
Company Merger be cancelled),  shall receive a cash payment  (without  interest)
equal to the fair market value at the Effective  Time of any fraction of a share
of Whitney  Common  Stock to which such holder  would be  entitled  but for this
provision.  For purposes of calculating such payment, the fair market value of a
fraction of a share of Whitney  Common Stock at the Effective Time shall be such
fraction multiplied by the Average Market Price.

                  (d) Exchange of  Certificates.  After the Effective Time, each
holder of an outstanding certificate or certificates  theretofore representing a
share or shares of Citizens  Common  Stock,  other than  Dissenters'  Shares and
shares of Citizens Common Stock held by Citizens as treasury shares (which shall
by reason of the Company  Merger be cancelled),  upon  surrender  thereof to the
exchange agent selected by Whitney (the  "Exchange  Agent"),  together with duly
executed  transmittal  materials  provided  pursuant to Section  2.01(e) or upon
compliance by the holder or holders  thereof with the procedures of the Exchange
Agent with respect to lost, stolen or destroyed certificates,  shall be entitled
to receive in exchange therefor any payment due in lieu of fractional shares and
a certificate or certificates representing the number of whole shares of Whitney
Common  Stock into which such  holder's  shares of  Citizens  Common  Stock were
converted.  Until so surrendered,  each outstanding  Citizens stock  certificate
shall be deemed for all purposes,  other than as provided  below with respect to
the payment of dividends or other  distributions  (if any) in respect of Whitney
Common Stock,  to represent  the number of whole shares of Whitney  Common Stock
into which such holder's Citizens Common Stock shall

                                       4

                                Page 27 of 63

<PAGE>



have been converted.  Whitney may, at its option,  refuse to pay any dividend or
other distribution to holders of unsurrendered Citizens stock certificates until
surrendered;  provided,  however,  that upon the  surrender  and exchange of any
Citizens  stock  certificates  there shall be paid, to the extent not previously
paid, to the record holders of the Whitney stock certificates issued in exchange
therefor  the  amount,   without   interest,   of   accumulated   dividends  and
distributions,  if any,  which have become payable with respect to the number of
whole shares of Whitney  Common  Stock into which the shares of Citizens  Common
Stock theretofore represented by such certificates shall have been exchanged.

                  (e) Deposit.  Promptly  following the Effective Time,  Whitney
shall deposit or cause to be deposited with the Exchange Agent (i)  certificates
representing  the  shares of Whitney  Common  Stock and (ii) the cash in lieu of
fractional  shares to be issued and paid,  as the case may be, in  exchange  for
outstanding shares of Citizens Common Stock pursuant to this Section 2.

                  (f) Transmittal Materials.  Promptly after the Effective Time,
Whitney shall send or cause to be sent to each former  shareholder  of record of
Citizens at the Effective  Time,  excluding the holders,  if any, of Dissenters'
Shares as to which  dissenters'  rights have been perfected and not withdrawn or
otherwise forfeited under Section 131 of the LBCL, transmittal materials for use
in exchanging  certificates of Citizens Common Stock for certificates of Whitney
Common Stock.

                  (g) Dissenters'  Shares.  Holders of Dissenters'  Shares shall
not be  entitled to receive  the shares of Whitney  Common  Stock and any unpaid
dividends and  distributions  payable thereon pursuant to Section 2.01 and shall
only be  entitled  to receive  payment of the fair cash value of such  shares in
accordance  with the  provisions  of Section  131 of LBCL  unless and until such
holders  fail to  perfect  or  effectively  withdraw  or lose  their  rights  to
appraisal and payment under the LBCL.  If, after the  Effective  Time,  any such
holder  fails to perfect or  effectively  withdraws  or loses such  right,  such
shares of Citizens  Common  Stock will be treated as if they had been  converted
into, at the  Effective  Time,  the shares of Whitney  Common Stock (and cash in
lieu of fractional  share),  and any unpaid dividends and distributions  payable
thereon pursuant to Section 2.01, without interest thereon.

         2.02.  Closing  Transfer  Books.   At  the  Effective  Time,  the stock
transfer books of Citizens shall be closed and no transfer of shares of Citizens
Common Stock shall be made thereafter.

         Section 3.  Representations and Warranties of Citizens

         Citizens and Bank  represent  and warrant to Whitney,  Acquisition  and
Whitney's Bank that, as of the date on which  Citizens  delivers the Schedule of
Exceptions  to Whitney  and as of the Closing  Date,  except as set forth in the
Schedule of Exceptions:

         3.01.  Consolidated  Group;  Organization;  Qualification.   "Citizens'

Citizens and the Bank.  Citizens is

a corporation  duly organized,  validly  existing and in good standing under the
laws of the State of Louisiana, and is a bank holding company within the meaning
of the Bank Holding  Company Act of 1956, as amended (the "Bank Holding  Company
Act").  The Bank is a national  banking  association,  duly  organized,  validly
existing  and in good  standing  under  the  laws of the  United  States  and is
domiciled in the State of Louisiana. Each member of Citizens' consolidated group
has all  requisite  corporate  power and authority to own and lease its property
and to carry on its business as it is currently  being  conducted and to execute
this  Agreement  and  the  Merger  Agreements  to  which  it is a  party  and to
consummate the transactions  contemplated  hereby,  and is qualified and in good
standing as a foreign  corporation in all  jurisdictions in which the failure to
so qualify  would  have a material  adverse  effect on such  member's  financial
condition, results of operations or business.

         3.02. Capital Stock; Other Interests.  The authorized capital stock (i)
of Citizens  consists of 10,000,000  shares of Citizens  Common Stock,  of which
1,266,219  shares are issued and  outstanding  and 41,310 shares are held in its

fully paid and (except as provided in 12 U.S.C. Section 55) non-assessable,  and
all of the outstanding shares of the Bank are owned by Citizens,  free and clear
of  all  liens,  charges,  security  interests,  mortgages,  pledges  and  other
encumbrances. Other than options to acquire up to an aggregate of 120,000 shares
of  Citizens  Common  Stock,  granted  under the  Option  Plans (as  hereinafter
defined),  no member of Citizens'  consolidated  group has outstanding any stock
options  or other  rights to  acquire  any  shares of its  capital  stock or any
security  convertible  into such shares,  or has any obligation or commitment to
issue,  sell or deliver any of the foregoing or any shares of its capital stock.
The outstanding capital stock of each member of Citizens' consolidated group has
been issued in compliance with all legal requirements and in compliance with any
preemptive or similar rights.  No member of Citizens'  consolidated  group has a
subsidiary (other than Bank) or direct or indirect  ownership interest exceeding
5% in any firm, corporation, partnership or other entity.

         3.03. Corporate Authorization; No Conflicts. Subject to the approval of
this Agreement and the Merger Agreements by the shareholders of Citizens and the
Bank, respectively,  in accordance with the LBCL and applicable federal law, all
corporate  acts and other  proceedings  required  of each  member  of  Citizens'
consolidated group for the due and valid authorization,  execution, delivery and
performance of this Agreement and the Merger  Agreements and consummation of the
Mergers have been validly taken.  Subject to their approval by the  shareholders
of Citizens  and the Bank and to such  regulatory  approvals  as are required by
law,  this  Agreement  and the Merger  Agreements  are legal,  valid and binding
obligations of Citizens and the Bank and are  enforceable  against  Citizens and
the Bank,  respectively,  in  accordance  with the  respective  terms hereof and
thereof,  except that enforcement may be limited by bankruptcy,  reorganization,
insolvency and other similar laws and court  decisions  relating to or affecting
the  enforcement  of  creditors'  rights  generally  and  by  general  equitable
principles. With respect to each member of Citizens' consolidated group, neither
the  execution,  delivery  or  performance  of  this  Agreement  or  the  Merger
Agreements, nor the

both, would  constitute a default) under,  (iii) result in the termination of or
accelerate  the  performance  required by, or (iv) result in the creation of any
lien,  security  interest,  charge or encumbrance  upon any of its properties or
assets  under,  any of the terms,  conditions  or  provisions of its articles of

                  The Financial Statements and, except as indicated in the notes
thereto or, as permitted by Form 10-Q and the rules and  regulations of the SEC,
the  Interim  Financial  Statements,  have  been (and all  financial  statements
delivered  to  Whitney  as  required  by this  Agreement  will be)  prepared  in
conformity with generally accepted  accounting  principles ("GAAP") applied on a
basis consistent with prior periods, and present fairly, in conformity with GAAP

its consolidated  group as of the respective  dates thereof.  All call and other
regulatory reports referred to above have been filed on the appropriate form and

"Latest Balance Sheet"), no member of Citizens'  consolidated group had, nor are
any of any such member's assets subject to, any material liability,  commitment,
indebtedness or obligation (of any kind whatsoever,  whether absolute,  accrued,
contingent, matured or unmatured) which is not reflected and adequately reserved
against in accordance with GAAP. No report,  including any report filed with the
Federal  Reserve  Board,  or  other  report,  proxy  statement  or  registration
statement filed by any member of Citizens'  consolidated group with the SEC, and
no report made to shareholders of Citizens,  as of the respective dates thereof,
contained and no such report, proxy statement,  registration statement or report
to  shareholders  filed or  disseminated  after the date of this  Agreement will
contain,  any untrue  statement of a material fact or omitted,  or will omit, to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not misleading.  The Financial  Statements and Interim Financial  Statements are
supported by and consistent with a general ledger and detailed trial balances of
investment  securities,  loans and  commitments,  depositors'  accounts and cash
balances  on  deposit  with other  institutions,  copies of which have been made
available to Whitney.

         3.05.  Loan  and  Investment  Portfolios.   All  loans,  discounts  and
financing leases (in which a member of Citizens'  consolidated  group is lessor)
reflected  on the  Latest  Balance  Sheet  (a)  were,  at the time and under the
circumstances in which made, made for good, valuable and adequate  consideration
in the ordinary course of business of its consolidated  group, (b) are evidenced
by genuine notes,  agreements or other evidences of indebtedness  and (c) to the
extent  secured,  have been secured by valid liens and security  interests which
have been  perfected,  except  (in the case of (c)  above)  for (x) such  loans,
discounts and financing leases for which specific reserves have been established
as of June 30, 1995,  and (y) such other loans,  discounts and financing  leases
(the  outstanding  principal  balances  of which do not exceed in the  aggregate
$2,000,000) having material issues of collectibility for which specific reserves
had not been  established  as of June 30,  1995.  Accurate  lists of all  loans,
discounts and financing  leases as of the date of the Latest Balance Sheet (or a
more recent date), and of the investment  portfolios of each member of Citizens'
consolidated  group as of such date,  have been delivered to Whitney.  Except as
specifically  noted on the loan schedule attached to the Schedule of Exceptions,
no member of Citizens' consolidated group is a party to any written or oral loan
agreement, note or borrowing arrangement, including any loan guaranty, that was,
as of the most  recent  month-end  (i)  delinquent  by more  than 30 days in the
payment  of  principal  or  interest,  (ii)  known by any  member  of  Citizens'
consolidated  group to be otherwise  in material  default for more than 30 days,
(iii) classified as "substandard,"  "doubtful," "loss," "other assets especially
mentioned"  or  any  comparable   classification  by  any  member  of  Citizens'
consolidated  group,  the OCC or the FDIC,  (iv) an  obligation of any director,
executive  officer or 10%  shareholder  of any member of Citizens'  consolidated
group who is subject to  Regulation  O of the Federal  Reserve  Board (12 C.F.R.
Part 215), or any person,  corporation or enterprise controlling,  controlled by
or under common  control with any of the  foregoing,  or (v) in violation of any
law, regulation or rule of any governmental authority, other than those that are
immaterial in amount.

         3.06.  Adequacy  of  Allowances for Losses.  Each of the allowances for
losses  on  loans,  financing  leases  and other real estate shown on the Latest
Balance Sheet is adequate in

                                       8

                                Page 31 of 63


<PAGE>



accordance  with  applicable  regulatory  guidelines  and  GAAP in all  material
respects,  and there are no facts or  circumstances  known to Bank's  Directors'
Loan Review  Committee which are likely to require in accordance with applicable
regulatory  guidelines or GAAP a future material increase in any such provisions
for losses or a material decrease in any of the allowances therefor reflected in
the Latest Balance Sheet except as contemplated by subsection  3.05(c)(y).  Each
of the  allowances for losses on loans,  financing  leases and other real estate
reflected  on the books of  Citizens'  consolidated  group at all times from and
after the date of the  Latest  Balance  Sheet is  adequate  in  accordance  with
applicable  regulatory  guidelines and GAAP in all material respects,  and there
are no facts or circumstances  known to Bank's  Directors' Loan Review Committee
which are likely to require in accordance with applicable  regulatory guidelines
or GAAP a future  material  increase in any of such  provisions  for losses or a
material  decrease in the  allowances  therefor  reflected in the Latest Balance
Sheet except as contemplated by subsection 3.05(c)(y).

         3.07.  Absence  of Certain  Changes  or  Events.  Since the date of the
Latest Balance Sheet,  no member of Citizens'  consolidated  group has declared,
set aside for  payment or paid any  dividend  to holders of, or declared or made
any distribution  on, any shares of Citizens'  capital stock for Citizens except
regular quarterly  dividends of $.15 per share payable September 29, 1995. Since
the date of the Latest  Balance  Sheet,  there has been no event or condition of
any character  (whether actual or threatened) that has had, or can reasonably be
anticipated  to have,  a material  adverse  effect on the  financial  condition,
results of operations or business of Citizens'  consolidated  group,  taken as a
whole.  Except  as  may  result  from  the  transactions  contemplated  by  this
Agreement, no such member has, since the date of the Latest Balance Sheet:

                  (a) borrowed  any money or entered into any capital  lease or,
except in the ordinary course of business  consistent  with past practices,  (i)
lent any money or pledged any of its credit in connection with any aspect of its
business  whether  as a  guarantor,  surety,  issuer  of a letter  of  credit or
otherwise,  (ii)  mortgaged or otherwise  subjected to any lien,  encumbrance or
other  liability any of its assets,  (iii) sold,  assigned or transferred any of
its assets in excess of $100,000 in the aggregate, or (iv) incurred any material
liability,  commitment,  indebtedness  or  obligation  (of any kind  whatsoever,
whether absolute or contingent);

                  (b)  suffered  any  material  damage,  destruction  or loss to
immovable or movable property, whether or not covered by insurance;

                  (c) experienced any material change in asset concentrations as
to customers or industries or in the nature and source of its  liabilities or in
the mix of interest-bearing versus non-interest bearing deposits;

                  (d) received notice or had knowledge or reason to believe that
any material  labor unrest  exists among any of its employees or that any group,
organization or union has attempted to organize any of its employees;



                                       9

                  (e) received notice that one or more substantial customers has
terminated or intends to terminate such  customers'  relationship  with it, with
the result being a material adverse effect on the Bank;

                  (f) failed to operate  its  business  in the  ordinary  course
consistent with past practices,  or failed to use reasonable efforts to preserve
its business  organization  intact or to preserve the goodwill of its  customers
and others with whom it has business relations;

                  (g) incurred any  material  loss except for losses  adequately
reserved  against on the date of this  Agreement or on the Latest  Balance Sheet
and expenses  associated with this transaction,  or waived any material right in
connection  with any  aspect of its  business,  whether  or not in the  ordinary
course of business;

                  (h)  forgiven any material debt owed to it, or canceled any of
its claims or paid any of its noncurrent obligations or liabilities;

                  (i)  made any  capital  expenditure  or  capital  addition  or

of) any  federal,  state  or local  law,  regulation,  ordinance,  rule or order
(whether executive, judicial, legislative or administrative) or any order, writ,
injunction or decree of any court, agency or instrumentality.

                  (c) There are no material  uncured  violations,  or violations

         3.11.  Employee Benefit Plans.  (a) Except  for the plans listed on the
subsection of the Schedule  of  Exceptions  that corresponds to this  subsection
(the  "ERISA  Plans"),  no  member  of  Citizens'  consolidated  group sponsors,
maintains or contributes to, and no such member has at

                                       12

                                Page 35 of 63

<PAGE>



any time sponsored, maintained or contributed to, any employee benefit plan that
is subject to any of the provisions of the Employee  Retirement  Income Security
Act of 1974, as amended  ("ERISA").  Each of the ERISA Plans has been maintained
and  administered  in all material  respects in compliance  with its terms,  the
provisions of ERISA and all other  applicable laws, and, where  applicable,  the
provisions of the Internal  Revenue Code of 1986,  as amended (the  "Code").  No
ERISA Plan,  including  any "party in  interest" or  "disqualified  person" with
respect thereto has engaged in a nonexempt prohibited  transaction under Section
4975 of the Code or Section 502(i) of ERISA;  there is no matter relating to any
of  the  ERISA  Plans  pending  or  threatened,  nor  are  there  any  facts  or
circumstances  existing that could reasonably be expected to lead to (other than
routine  filings  such  as  qualification  determination  filings),  proceedings
before,  or  administrative  actions by, any governmental  agency;  there are no
actions, suits or claims pending or threatened  (including,  without limitation,
breach of fiduciary duty actions,  but excluding routine  uncontested claims for
benefits)  against any of the ERISA Plans or the assets thereof.  Each member of
Citizens'  consolidated  group has  complied in all material  respects  with the
reporting and disclosure  requirements  of ERISA and the Code. None of the ERISA
Plans is a  multi-employer  plan within the meaning of Section 3(37) of ERISA. A
favorable  determination  letter has been issued by the Internal Revenue Service
with respect to each ERISA Plan that is intended to be qualified  under  Section
401(a)  of the Code and the  Internal  Revenue  Service  has  taken no action to
revoke any such letter and nothing has occurred, whether by action or failure to
act,  which would cause the loss of such  qualification.  No member of Citizens'
consolidated group has sponsored,  maintained or made contributions to any plan,
fund or arrangement  subject to Title IV of ERISA or the requirements of Section
412 of the Code or providing for medical benefits,  insurance  coverage or other
similar  benefits for any period extending beyond the termination of employment,
except as may be required under the "COBRA" provisions of ERISA and the Code.

                  (b) Set forth on the  subsection of the Schedule of Exceptions
corresponding  to this  subsection  is a true and complete  list of each benefit
plan and benefit arrangement of any member of Citizens' consolidated group other
than the ERISA Plans.  True and  complete  copies of all plan  (including  ERISA
Plan)   documents  and  written   agreements   (including   all  amendments  and
modifications  thereof),  together with copies of any tax determination letters,
trust agreements,  summary plan descriptions,  insurance  contracts,  investment
management  agreements  and the three most recent annual  reports on form series
5500 with  respect  to such plan or  arrangement  have  been made  available  to
Whitney.

                  (c)  All  group  health  plans  of  any  member  of  Citizens'
consolidated group to which Section 4980B(f) of the Code or Section 601 of ERISA
applies are in compliance in all material  respects with  continuation  coverage
requirements  of Section  4980B(f)  of the Code and Section 601 of ERISA and any
prior violations of such sections have been cured prior to the date hereof.

                  (d) Each plan,  fund or  arrangement  previously  sponsored or
maintained by any member of Citizens' consolidated group, or to which any member
of Citizens'  consolidated  group previously made  contributions  which has been
terminated  by any member of  Citizens'  consolidated  group was  terminated  in
accordance with ERISA, the Code and the terms of such

                                       13

                                Page 36 of 63

<PAGE>



plan, fund or arrangement and no event has occurred and no condition exists that
would subject any member of Citizens'  consolidated group, Whitney,  Acquisition
or Whitney's Bank to any tax,  penalty,  fine or other liability as a result of,
directly or indirectly, the termination of such plan, fund or arrangement.

                  (e) The current  fair market value of the assets of each ERISA
Plan  subject  to the  provisions  of Title IV of ERISA  equals or  exceeds  the
present  value of the  accrued  benefits  of each such plan as of the end of the
most recent plan year, calculated on a termination and on-going basis, and there
has been no  material  change  likely to change the  funding  status of any such
plan. No funding deficiency within the meaning of Section 412 of the Code exists
with respect to any ERISA Plan. All contributions  required or accrued under the
terms of any plan  (including  any ERISA Plan) have been made and all  insurance
premiums  required or accrued under the terms of any plan  (including  any ERISA
plan) have been paid as of the date hereof.

         3.12. Insurance Policies.  Each member of Citizens'  consolidated group
maintains in force insurance policies and bonds in such amounts and against such
liabilities and hazards as are considered by it to be adequate. An accurate list
of all such  insurance  policies is attached to the Schedule of  Exceptions.  No
member of Citizens'  consolidated  group is now liable,  nor has any such member
received any notice of any material retroactive premium adjustment. All policies
are  valid  and  enforceable  and in full  force  and  effect,  and no member of
Citizens'  consolidated  group has  received  any notice of a  material  premium
increase or cancellation with respect to any of its insurance policies or bonds.
Within the last three years, no member of Citizens'  consolidated group has been
refused any basic  insurance  coverage sought or applied for (other than certain
exclusions  for coverage of certain  events or  circumstances  as stated in such
polices).

         3.13.  Agreements.  (a)  No member of Citizens' consolidated group is a
party to:

                           (i)  any collective bargaining agreement;

policies  and  practices referred to in the  exceptions to  subparagraph  (j) of
subsection  3.07 of this Agreement and such agreements as are terminable without
penalty upon not more than 30 days notice by the employer;

                           (iii)  any  obligation of guaranty or indemnification

in their respective  articles  of   incorporation  or  association  and  by-laws
(and no indemnification of any such officer,  director, employee  or  agent  has
been authorized,  granted or awarded),  except  if entered  into in the ordinary
course  of  business  with  respect  to  customers  of  any  member of Citizens'
consolidated   group,  letters   of  credit,   guaranties  of  endorsements  and
guaranties  of signatures;

regulatory guidelines to be  engaged in by bank  holding  companies or Louisiana
state or national banks, as applicable to the Bank, or (z) to fulfill any of its
requirements  or  needs  for  services  or  products  (including,  for  example,
contracts  with vendors to supply customers with credit insurance); or

                           (vi)  any  written  agreement,  memorandum,   letter,
order  or  decree,  formal  or  informal,  with  any federal or state regulatory
agency.

                  (b)  The  subsection  of  the  Schedule  of  Exceptions   that
corresponds  to this  subsection  contains  a list of each  material  agreement,
contract or  commitment  (except  those  entered into in the ordinary  course of
business with respect to loans,  lines of credit,  letters of credit,  depositor
agreements, certificates of deposit and similar banking activities and equipment
maintenance  agreements which are not material) to which any member of Citizens'
consolidated  group is a party or which  affects any such  member.  To Citizens'
knowledge, no member of Citizens' consolidated group has in any material respect
breached,  nor is there any pending or threatened  claim that it has  materially
breached, any of the terms or conditions of any of such agreements, contracts or
commitments.

transfer  records of each member of  Citizens'  consolidated  group are current,
complete and correct in all material respects.

equitable principles. With respect to each of Whitney, Acquisition and Whitney's
Bank,  neither the  execution,  delivery or performance of this Agreement or the

or  thereby  will (i)  violate,  conflict  with,  or  result  in a breach of any
provision of, (ii) constitute a default (or an event which, with notice or lapse
of time or  both,  would  constitute  a  default)  under,  (iii)  result  in the
termination of or accelerate the performance  required by, or (iv) result in the

Financial  Statements  (each as defined in Schedule  4.04) have been prepared in
conformity  with GAAP  applied on a basis  consistent  with prior  periods,  and
present fairly, in conformity with GAAP, the consolidated  results of operations
of Whitney's  consolidated  group for the respective periods covered thereby and
the  consolidated  financial  condition  of  its  consolidated  group  as of the
respective dates thereof.  All call and other regulatory reports have been filed
on the appropriate form and prepared in all material respects in accordance with
such  form's  instructions  and the  applicable  rules  and  regulations  of the
regulating  federal  agency.  As of the date of the latest balance sheet forming
part of the Whitney  Interim  Financial  Statements (the "Whitney Latest Balance
Sheet"),  no member of Whitney's  consolidated group had, nor were any of any of
such  member's   assets   subject  to,  any  material   liability,   commitment,

which is not reflected and  adequately  reserved  against in the Whitney  Latest
Balance  Sheet in  accordance  with GAAP.  No report filed with Federal  Reserve
Board or  other  bank  regulatory  body,  as of the  respective  dates  thereof,
contained  and no such  report  filed  after  the  date of this  Agreement  will
contain,  any untrue  statement of a material fact or omitted,  or will omit, to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances in which they were made, not
misleading.

         4.05.  Legality  of Whitney  Securities.  All shares of Whitney  Common
Stock to be issued pursuant to the Company Merger have been duly authorized and,
when  issued  pursuant  to the  Company  Merger  Agreement,  will be validly and

delivery, free and clear of all liens, charges,  security interests,  mortgages,
pledges and other encumbrances and any preemptive or similar rights.

         4.06.  SEC  Reports.  Whitney has  previously  delivered to Citizens an
accurate and complete copy of the following  Whitney  reports filed with the SEC
pursuant  to the  Exchange  Act:  (a) annual  reports on Form 10-K for the years
ended December 31, 1992,  1993 and 1994; (b) quarterly  reports on Form 10-Q for
the three months ended March 31 and June 30, 1995; and (c) proxy  statements for
the years 1993, 1994 and 1995; as of their  respective  dates, no such Report or
communication  contained  any untrue  statement of a material fact or omitted to
state any material fact  required to be stated  therein or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not  misleading.  Whitney has timely filed all reports and other documents
required to be filed by it under the Securities Act and the Exchange Act.

         4.07.  Absence  of Certain  Changes  or  Events.  Since the date of the
Whitney  Latest  Balance  Sheet,  there  has been no event or  condition  of any
character  (whether  actual or  threatened)  that has had, or can  reasonably be
anticipated  to have,  a material  adverse  effect on the  financial  condition,
results of  operations  or business of Whitney's  consolidated  group taken as a
whole.

         4.08.  Legal Matters.  (a)   There  are  no  material  actions,  suits,
proceedings, arbitrations  or  investigations pending or, to Whitney's knowledge
threatened, against any member of

Whitney's  consolidated  group which would be required to be disclosed in a Form
10-K or Form 10-Q pursuant to Item 103 of Regulation  S-K of the SEC's Rules and
Regulations that are not so disclosed.

                  (b) There are no material  uncured  violations,  or violations
with respect to which material refunds or restitution may be required,  cited in
any compliance report to any member of Whitney's  consolidated group as a result
of examination by any bank or bank holding company regulatory authority.

                  (c) No member of  Whitney's  consolidated  group is subject to
any written agreement, memorandum or order or decree with or by any bank or bank
holding company regulatory authority.

         4.09. Accuracy of Statements.  No warranty or representation made or to
be made by any member of Whitney's  consolidated  group in this  Agreement or in
any  document   furnished  or  to  be  furnished  by  any  member  of  Whitney's
consolidated  group pursuant to this Agreement  contains or will contain,  as of
the date of this Agreement, the effective date of the Registration Statement (as
defined in Subsection 5.14 hereof) and the Closing Date, an untrue  statement of
a  material  fact or an  omission  of a  material  fact  necessary  to make  the
statements  contained herein and therein, in light of the circumstances in which
they are made, not misleading.

         Section 5.  Covenants  and  Conduct  of  Parties Prior to the Effective
Date.  The parties further covenant and agree as follows:

         5.01.   (a)   Investigations;   Planning.   Each  member  of  Citizens'
consolidated  group  shall  continue  to provide  to  Whitney,  Acquisition  and
Whitney's Bank and to their  authorized  representatives  full access during all
reasonable  times to its  premises,  properties,  books and records  (including,
without  limitation,  all corporate minutes and stock transfer records),  and to
furnish Whitney,  Acquisition and Whitney's Bank and such  representatives  with
such financial and operating data and other  information of any kind  respecting
its business and  properties as Whitney,  Acquisition  and Whitney's  Bank shall
from time to time reasonably request.  Any investigation shall be conducted in a
manner which does not unreasonably  interfere with the operation of the business
of Citizens'  consolidated  group. Each member of Citizens'  consolidated  group
agrees to cooperate with Whitney,  Acquisition  and Whitney's Bank in connection
with planning for the efficient and orderly  combination  of the parties and the
operation of Whitney,  Acquisition and Whitney's Bank after  consummation of the
Mergers.  In the event of termination  of this Agreement  prior to the Effective
Date,  Whitney and Acquisition  shall,  except to any extent necessary to assert
any  rights  under this  Agreement  or the Merger  Agreements,  return,  without
retaining  copies  thereof,  or destroy  (and  certify to same under  penalty of
perjury)  all  confidential  or  non-public  documents,  work  papers  and other
materials  obtained from  Citizens'  consolidated  group in connection  with the
transactions  contemplated hereby and shall keep such information  confidential,
not disclose  such  information  to any other person or entity  except as may be
required by legal process,  and not use such  information in connection with its
business,  and shall cause all of its employees,  agents and  representatives to
keep such  information  confidential  and not to disclose such information or to
use it in connection

                                       21

with its  business,  in each case unless and until such  information  shall come
into the public domain  through no fault of Whitney,  Acquisition  and Whitney's
Bank.  Whitney and Whitney's Bank shall continue to provide Citizens'  executive
officers  with access to their  respective  executive  officers,  during  normal
business hours and upon reasonable  notice,  to discuss the business and affairs
of Whitney and Whitney's  Bank to the extent  customary in  transactions  of the
nature contemplated by this Agreement.

                  (b)  Delivery  of  Schedules  of  Exceptions;  Due  Diligence.
Whitney and Citizens  stipulate that they have entered into this Agreement prior
to Citizens'  delivery of its  consolidated  group's  Schedule of Exceptions and
prior to Whitney's completion of Whitney's customary due diligence investigation
of  Citizens.  Citizens  shall  deliver  to  Whitney,  on or before the 14th day
following the date hereof, its consolidated group's Schedule of Exceptions. Upon
such  delivery,  such  Schedules  shall be  initialed  on behalf of Whitney  and
Citizens,  shall  be  appended  hereto  and  shall  form a part  hereof  for all
purposes.  If Citizens  fails to deliver its  consolidated  group's  Schedule of
Exceptions  on or before the 14th day  following  the date  hereof,  Whitney may
terminate  this  Agreement   without  liability  by  giving  written  notice  of
termination  to  Citizens.  Whitney's  due  diligence  review shall be concluded
during a 21 calendar day period  commencing on the first  business day following
Citizens'  delivery to Whitney of its Schedule of Exceptions as provided  herein
(the "Review Period").  At or prior to expiration of the Review Period,  Whitney
shall elect, by written notice to Citizens, to either (a) proceed to the Closing
(subject to the  satisfaction  or waiver of all other  conditions to Closing) or
(b) terminate the Agreement (without liability to Citizens or the Bank except as
set forth in the last  sentence  of this  Section  5.01(b))  if, in its sole and
absolute discretion,  it is not satisfied with the results of such due diligence
review or for any  other  reason.  Absent  timely  delivery  of  written  notice
electing to terminate this Agreement, Whitney shall be deemed to have elected to
proceed  to the  Closing,  subject  to all other  terms and  conditions  of this
Agreement. If, after receiving Citizens' Schedule of Exceptions,  Whitney elects
to  terminate  this  Agreement  pursuant to the sixth  sentence of this  Section
5.01(b),  then  notwithstanding  any  other  provision  hereof,   Whitney  shall
reimburse Citizens for the reasonable  out-of-pocket  expenses actually incurred
by it in connection with the transactions contemplated by this Agreement through
the date of termination up to a maximum of $150,000.

         5.02.  Cooperation  and Best Efforts.  Each of the parties  hereto will
cooperate  with the other  parties  and use its best  efforts to (a) procure all
necessary  consents and approvals of third  parties,  (b) complete all necessary
filings,  registrations,  applications,  schedules and certificates, (c) satisfy
all  requirements  prescribed by law for, and all  conditions  set forth in this
Agreement to, the consummation of the Mergers and the transactions  contemplated
hereby  and  by  the  Merger   Agreements,   and  (d)  effect  the  transactions
contemplated  by  this  Agreement  and the  Merger  Agreements  at the  earliest
practicable date.

         5.03.  Information for, and Preparation of, Registration  Statement and
Proxy Statement. Each of the parties hereto will cooperate in the preparation of
the Registration  Statement referred to in Section 5.14 and a proxy statement of
Citizens (the "Proxy  Statement")  which complies with the  requirements  of the
Securities Act of 1933 (the  "Securities  Act"), the Exchange Act, the rules and
regulations promulgated thereunder and other applicable federal and

                                       22

                                Page 45 of 63


<PAGE>



state laws,  for the purpose of submitting  this  Agreement,  the Company Merger
Agreement  and the  transactions  contemplated  hereby and thereby to  Citizens'
shareholders  for approval.  Each of the parties will as promptly as practicable
after the date hereof furnish all such data and  information  relating to it and
its  subsidiaries  as any of the other  parties may  reasonably  request for the
purpose of including such data and information in the Registration Statement and
the Proxy Statement.

         5.04.  Approval of Merger Agreements.  Whitney, as the sole shareholder
of  Acquisition  and  Whitney's  Bank, shall take all action necessary to effect
shareholder approval of the Merger Agreements.

         5.05.  Press  Releases.  Whitney and Citizens will  cooperate with each
other in the preparation of any press releases  announcing the execution of this
Agreement or the consummation of the transactions  contemplated hereby.  Without
the prior written consent of the chief executive  officer of the other party, no
member of  Citizens'  consolidated  group or Whitney's  consolidated  group will
issue any press  release or other  written  statement  for  general  circulation
relating to the  transactions  contemplated  hereby,  except as may otherwise be
required by law and, if  practical,  prior notice of such release is provided to
the other parties. Whitney agrees that it will make a press release with respect
to the results of operations of Whitney and its  consolidated  group as promptly
as practicable  following  receipt of financial results covering at least thirty
(30)  days  of  post-mergers  combined  operations  of  Whitney  to  permit  the
termination of the limitations  set forth in the Shareholder  Commitments on the
ability of each person  referred to in Section 5.10 to resell  shares of Whitney
Common Stock in a manner  inconsistent with Whitney's ability to account for the
Mergers as a pooling of interests.

         5.06.  Preservation  of Business.  To the extent  consistent with sound
business  practices,  each member of Citizens'  consolidated  group will use its
best efforts to preserve the  possession  and control of all of its assets other
than those consumed or disposed of for value in the ordinary  course of business
to preserve the goodwill of customers and others having business  relations with
it and to do nothing  knowingly  to impair its ability to keep and  preserve its
business as it exists on the date of this Agreement.

         5.07.  Conduct of  Business  in the  Ordinary  Course.  Each  member of
Citizens'  consolidated  group shall  conduct its business  only in the ordinary
course consistent with past practices,  and shall not, without the prior written
consent  of the  chief  executive  officer  of  Whitney  or his duly  authorized
designee:

                  (a)  except  for the  declaration  and  payment  of (i) a 1995
year-end dividend, which, when combined with the other four dividends previously

taxes  for 1995 of  Citizens'  consolidated  group  and (ii)  regular  quarterly
dividends  during  1996 in the amount of $.15 per share (at the  customary  time
each  quarter)  until the  Effective  Time of the Mergers,  declare,  set aside,
increase  or pay any  dividend,  or  declare  or make any  distribution  on,  or
directly or  indirectly  combine,  redeem,  reclassify,  purchase,  or otherwise
acquire,  any shares of its capital  stock or authorize the creation or issuance
of or issue any additional shares of its capital stock or any

                                       23

securities  or  obligations  convertible  into or  exchangeable  for its capital
stock,   provided  that  this  subparagraph   shall  not  prevent  dividends  or
distributions  from any  member  of  Citizens'  consolidated  group to any other
member of such consolidated  group or any issuance of shares of capital stock of
Citizens  upon  exercise of options  granted  prior to the date hereof under the
Option Plans (as defined herein);

penalty  or  other  payment  by it,  or  increase  the  compensation  (including
salaries, fees, bonuses, profit sharing, incentive, pension, retirement or other
similar  benefits and  payments)  of any such person in any manner  inconsistent
with its past practices;  (ii) after consultation with Whitney's chief executive
officer,  bonuses to non- executive  officers in amounts in an aggregate  amount
not  exceeding  $150,000  and (iii)  December  1995  bonuses in  addition to the
bonuses  set forth in  Section  5.07(c)(ii)  to  employees  not to exceed in the
aggregate $525,000;

                  (d) except as  described  in the  Schedule  of  Exceptions  or
except in the ordinary course of business consistent with past practices,  place
or suffer to exist on any of its  assets or  properties  any  mortgage,  pledge,
lien, charge or other  encumbrance,  except those of the character  described in
subsection 3.09 hereof, or cancel any material  indebtedness  owing to it or any
claims which it may have possessed,  or waive any right of substantial  value or
discharge or satisfy any material noncurrent liability;

                  (e)  acquire  another  business or merge or  consolidate  with

the conditions to the Mergers set forth in Section 6 not being satisfied,  or in
a violation of any provision of this Agreement, except, in every case, as may be
required by applicable law;

                  (g)  commit or fail to take any act which act or  omission  is
intended  or  reasonably  may be  expected  to  result in a  material  breach or
violation of any  applicable  law,  statute,  rule,  governmental  regulation or
order;

                  (h)  fail to maintain its  books,  accounts and records in the
usual manner on a basis consistent with that heretofore employed;



                                       24

authorities  or by GAAP  consistently  applied) or sell  (except for a price not
materially less than the value thereof) any of its portfolio of loans, discounts

of any member of its consolidated  group, any material breach by any such member
of any of its warranties, representations or covenants in this Agreement, or any
material  action taken or proposed to be taken with respect to any member of its
consolidated  group  by any  regulatory  agency,  (b) as  soon  as  they  become
available,  copies of any financial  statements,  reports and other documents of
the type  referred  to in  subsection  3.04 with  respect to each  member of its
consolidated  group,  and  (c)  promptly  upon  its  dissemination,  any  report
disseminated to its shareholders.

         5.09.  Citizens  Shareholder  Approval.  Citizens'  Board of  Directors
shall submit this Agreement and the Company Merger Agreement to its shareholders
for  approval  in  accordance  with  the   applicable  law,  together  with  its
recommendation  that  such  approval  be  given,  at  a  special  meeting of the
shareholders  of  Citizens  duly called and convened for that purpose as soon as
practicable after the effective date of  the Registration  Statement.  Citizens,
as the sole

                                       25

shareholder of the Bank, shall take all action to effect shareholder approval of
the Bank Merger Agreement.

         5.10.  Restricted  Whitney  Common  Stock.  Citizens  will use its best
efforts to obtain by the  Closing  Date an  agreement  from each person who is a
director, executive officer or 5% beneficial owner of securities of Citizens who
will  receive  shares of Whitney  Common  Stock by virtue of the  Mergers to the
effect that such person will not dispose of any Whitney  Common  Stock  received
pursuant to the Mergers in  violation of Rule 145 of the  Securities  Act or the
rules and regulations of the SEC thereunder or in a manner that would disqualify
the  transactions  contemplated  hereby  from  pooling of  interests  accounting
treatment.

         5.11. Loan Policy. No member of Citizens'  consolidated group will make
any loans, or enter into any commitments to make loans, which vary other than in
immaterial  respects from its written loan policies,  a true and correct copy of
which loan  policies  will be provided to Whitney  concurrently  with  Citizens'
Schedule of Exceptions,  provided that this covenant shall not prohibit the Bank
from  extending or renewing  credit or loans in the ordinary  course of business
consistent  with past  lending  practices or in  connection  with the workout or
renegotiation of loans currently in its loan portfolio.

         5.12.  No  Solicitations.  Prior to the  Effective  Time or  until  the
termination of this Agreement,  no member of Citizens' consolidated group shall,
without  the prior  approval  of Whitney,  directly  or  indirectly,  solicit or
initiate  inquiries  or  proposals  with  respect  to, or,  except to the extent
determined  by  the  Board  of  Directors  of  Citizens  in  good  faith,  after
consultation with its financial  advisors and its legal counsel,  to be required
to discharge properly the directors' fiduciary duties to Citizens'  consolidated
group and its shareholders,  furnish any information relating to, or participate
in any negotiations or discussions  concerning,  any Acquisition Transaction (as
defined  in  Section  7.01) or any other  acquisition  or  purchase  of all or a
substantial  portion of its assets, or of a substantial equity interest in it or
withdraw its  recommendation  to the  shareholders of Citizens of the Mergers or
make a  recommendation  of any other  Acquisition  Transaction,  or any business
combination  with it, other than as  contemplated  by this  Agreement (and in no
event will any such information be supplied except pursuant to a confidentiality
agreement in form and substance as to confidentiality  substantially the same as
the  confidentiality  agreement  between  Citizens and  Whitney);  and each such
member shall instruct its officers,  directors, agents and affiliates to refrain
from doing any of the above,  and will notify  Whitney  immediately  if any such
inquiries or proposals  are  received by it, any such  information  is requested
from it, or any such negotiations or discussions are sought to be initiated with
it or any of its officers, directors, agents and affiliates;  provided, however,
that  nothing  contained  herein  shall be deemed to  prohibit  any  officer  or
director  of  Citizens  or the Bank from  taking  any  action  that the Board of
Directors of Citizens or the Bank, as the case may be, determines, in good faith
after consultation with and receipt of an opinion of counsel, is required by law
or is required to discharge his fiduciary duties to Citizens' consolidated group
and its shareholders.

         5.13.  Operating  Functions.  Each  member  of  Citizens'  consolidated
group  agrees  to  cooperate  in  the  consolidation  of  appropriate  operating
functions with Whitney to be effective

                                       26

                                Page 49 of 63


<PAGE>



on the  Effective  Date,  provided  that the  foregoing  shall  not be deemed to
require any action that,  in the opinion of such  member's  Board of  Directors,
would adversely affect its operations if the Mergers were not consummated.

         5.14. Whitney Registration Statement. (a) Whitney will prepare and file
on Form S-4 a registration  statement (the  "Registration  Statement") under the
Securities Act (which will include the Proxy  Statement)  complying with all the
requirements of the Securities Act applicable  thereto,  for the purpose,  among
other things,  of  registering  the Whitney Common Stock which will be issued to
the holders of Citizens Common Stock pursuant to the Mergers.  Whitney shall use
its best efforts to cause the Registration Statement to become effective as soon
as practicable, to qualify the Whitney 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. As a result of the
registration of the Whitney Common Stock pursuant to the Registration Statement,
such stock shall be freely  tradeable by the  shareholders of Citizens except to
the extent that the transfer of any shares of Whitney  Common Stock  received by
shareholders  of  Citizens  is subject to the  provisions  of Rule 145 under the
Securities Act or restricted under applicable tax or pooling of interests rules.

                  (b) Whitney will  indemnify  and hold  harmless each member of
Citizens'  consolidated group and each of their respective  directors,  officers
and other  persons,  if any,  who  control  Citizens  within the  meaning of the
Securities  Act from and against any losses,  claims,  damages,  liabilities  or
judgments,  joint or several,  to which they or any of them may become  subject,
insofar as such losses, claims, damages,  liabilities,  or judgments (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  in  any  state
application  for   qualification,   permit,   exemption  or  registration  as  a
broker/dealer, or in any amendment or supplement thereto, or arise out of or are
based upon 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 by such person in connection with investigating or defending
any such action or claim;  provided,  however, that Whitney shall not be liable,
in any such case, to the extent that any such loss, claim, damage, liability, or
judgment  (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 thereto,
or in any such state application,  or in any amendment or supplement thereto, in
reliance upon and in conformity with information written furnished to Whitney by
or on  behalf of any  member of  Citizens'  consolidated  group or any  officer,
director or affiliate of any such member for use therein.

         5.15.  Application to Regulatory Authorities.   Whitney  shall prepare,
as promptly as practicable,  all  regulatory  applications and filings which are
required to be made with respect to the Mergers.



                                       27

                                Page 50 of 63


<PAGE>



         5.16.  Revenue Ruling.  Whitney may elect to prepare (and in that event
Citizens shall  cooperate in the preparation of) a request for a ruling from the
Internal  Revenue Service with respect to certain tax matters in connection with
the transactions contemplated by this Agreement and the Merger Agreements.

         5.17.  Bond for Lost  Certificates.  Upon receipt of notice from any of
its shareholders that a certificate  representing Citizens Common Stock has been
lost or destroyed and prior to issuing a new certificate, Citizens shall require
such  shareholder  to post a bond in such amount as is sufficient to support the
shareholder's  agreement  to  indemnify  Citizens  against any claim made by the
owner of such  certificate,  unless  Whitney  agrees to the  waiver of such bond
requirement.

         5.18. Dissenters. Citizens shall give Whitney (i) prompt written notice
of, and a copy of, any  instrument  received  by  Citizens  with  respect to the
assertion or  perfection  of  dissenters  rights,  and (ii) the  opportunity  to
participate  in any  and  all  negotiations  and  proceedings  with  respect  to
dissenters rights, should Whitney desire to do so.

         5.19.  Withholding.  Whitney  shall be entitled to deduct and  withhold
from the consideration  otherwise payable to any holder of Citizens Common Stock
after the  Effective  Time such  amounts as Whitney  may be  required  by law to
deduct and withhold  therefrom.  All such deductions and  withholdings  shall be
deemed for all purposes of this Agreement and the Merger Agreements to have been
paid to the person with respect to whom such deduction and withholding was made.

         5.20.  NASDAQ/NMS.  Whitney  shall  cause the shares of Whitney  Common
Stock to be issued in the Merger to be duly  authorized,  validly issued,  fully
paid and  nonassessable,  free of any  preemptive  or  similar  right  and to be
approved for inclusion for trading in the NASDAQ/NMS, subject to official notice
of issuance, prior to the Effective Time.

         5.21.  Continuing Indemnity; Insurance.   Whitney  covenants and agrees
that:

                  (a) all  rights  to  indemnification  and all  limitations  of
liability  existing in favor of indemnified  parties under Citizens' Articles of
Incorporation  and By-Laws and in the Articles of Association and By-Laws of the
Bank (as the case may be) as in  effect  as of the date of this  Agreement  with
respect to matters occurring prior to or at the Effective Time shall survive the
Mergers  and shall  continue in full force and  effect,  without  any  amendment
thereto,  for a period of three (3) years  from the  Effective  Time;  provided,
however,  that all rights to indemnification in respect of any claim asserted or
made as to which Whitney is notified within such period shall continue until the
final disposition of such claim.

                  (b)  Whitney  shall  use best  efforts  to cause  the  persons
serving as officers and directors of Citizens and Bank immediately  prior to the
Effective  Time to be covered for a period of three (3) years from the Effective
Time by the directors' and officers'  liability  insurance policy  maintained by
Citizens and Bank with respect to acts or omissions occurring prior to or at the
Effective Time which were committed by such officers and directors in their

                                       28

                                Page 51 of 63


<PAGE>



capacity as such;  provided that Whitney may substitute  therefor policies of at
least the same coverage and amounts containing terms and conditions which are no
less  advantageous to such directors and officers,  and,  provided  further that
Whitney  shall not be  obligated  to make  premium  payments  for the  insurance
policies  provided by this Section 5.21 to the extent such premiums  exceed 150%
of the premiums paid as of the date hereof by Citizens for such insurance.

                  (c) If Whitney or any of its  successors  or assigns (i) shall
consolidate  with or merge into any  corporation  or entity and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii) shall transfer all or substantially all of its properties and assets to any
individual,  corporation  or other  entity,  then and in each such case,  proper
provisions  shall be made so that the  successors  and assigns of Whitney  shall
assume the obligations set forth in this Section 5.21.

                  (d) The provisions of this Section 5.21 are intended to be for
the benefit of, and shall be enforceable by, each  indemnified  party and his or
her heirs and representatives.

         5.22.  Stock Option Plans.

                  (a) On or prior to the Effective  Time,  Whitney and its Board
of  Directors  (or a  committee  thereof)  will take all  actions  necessary  to
implement the provisions contained in Sections 5.22(b) and (c), below.

                  (b)  Replacement  Options.  Whitney will assume the rights and
obligations of Citizens  pursuant to the stock options  outstanding  immediately
prior to the  Effective  Date  under its 1993  Stock  Option  Plan (a "1993 Plan
Option")  and its 1994 Stock Option Plan (a "1994 Stock  Option",  and each such
stock  option  existing  immediately  prior  to the  Effective  Date  called  an
"Existing Stock Option" and each such assumed stock option existing  immediately
after the  Effective  Date  called an  "Replacement  Option"  and the 1993 Stock
Option  Plan and 1994 Stock  Option  Plan are  collectively  referred  to as the
"Option Plans"). The terms of such assumption shall be as follows:

                           (i)      Under the Replacement Option,  the  optionee
shall have the right to purchase  the number of whole  shares of Whitney  Common
Stock  equal  to  the product  obtained  by multiplying  the number of shares of
Citizens Common Stock subject to such option immediately  prior to the Effective
Time by the Exchange Ratio,  rounded up to the nearest whole number of shares of
Whitney Common Stock, and the per share exercise price for the shares of Whitney
Common Stock issuable upon the exercise of such assumed options shall  be  equal
to the  quotient obtained by dividing the exercise  price per share of  Citizens
Common  Stock  specified  under  the  plan or agreement immediately prior to the
Effective Time by the Exchange Ratio, rounding the resulting exercise price down
to the nearest whole cent.

                           (ii)     The  Replacement  Option  shall not give the
optionee  additional  benefits  which  he  did not have under the Existing Stock
Option.


                                       29

                                Page 52 of 63


<PAGE>



                           (iii)    No later  than  the  Effective Time, Whitney
shall  reserve  for  issuance  the number of shares of Whitney Common Stock that
will become  issuable upon the exercise of the Replacement Options.

                           (iv)     Each  Replacement  Option  shall  constitute
a continuation  of  the  Existing Stock Option  substituting  (where applicable)
Whitney for Citizens and  employment by Whitney or any of its  subsidiaries  for
employment  by  Citizens  or  any  of  its  subsidiaries.   Notwithstanding  the
foregoing,  as to a 1993 Plan Option,  the terms of any Replacement Option shall
be such that the substitution of the  Replacement  Option for the Existing Stock
Option  would  not  constitute  a  modification  of the  Existing  Stock  Option
within  the  meaning of  Section 425(h)(3) of the Internal Revenue Code of 1986,
as amended (the  "Code"),  and regulations promulgated thereunder, if such apply
to the Existing Stock Option.

                           (v)      As  soon  as practicable after the Effective
Time, Whitney shall execute  a  document evidencing the assumption by Whitney of
the Existing Stock Options.

                  (c)  Registration.  As soon as practicable after the Effective
Time,  Whitney shall file with the SEC a  Registration  Statement on Form S-8 or
Form S-3 (or any  successor  forms)  with  respect to the  issuance or resale of
shares of Whitney Common Stock subject to the Replacement  Options and shall use
its best efforts to have such  Registration  Statement  declared  effective  and
thereafter to maintain the effectiveness of such  Registration  Statement for so
long as such options remain outstanding.

                  (d)  Notwithstanding   the  foregoing,   if  Whitney  receives
assurances  satisfactory  to it  in  its  sole  discretion  that  it  can  grant
replacement  options  in respect of the 1994  Stock  Options  to  eliminate  the
effects of (i)  paragraph  5 of the  agreements  with  respect to the 1994 Stock
Options and (ii) paragraphs 6(e) and 6(f) of the 1994 Stock Option Plan, and the
grant of these replacement options will not disqualify the Mergers as a "pooling
of interests" for accounting purposes, then Whitney shall grant such replacement
options.

         5.23.  Employees and Certain Other  Matters.  All employees of Citizens
and Bank at the  Effective  Time  shall  become  employees  of  Whitney's  Bank.
Although   Whitney's  present  intention  is  to  retain  Citizens'  and  Bank's
employees,  Whitney's Bank retains the right to terminate any such employee, and
to modify the job duties,  compensation  and authority of such employee.  At the
Effective Time, all persons then employed by Citizens and Bank shall be eligible
for such employee benefits as are generally  available to employees of Whitney's
Bank having like tenure,  officer status and compensation  levels except (i) all
executive and senior level management bonuses,  stock options,  restricted stock
and similar  benefits shall be the discretion of Whitney's  Bank's  Compensation
Committee  and (ii) all  Citizens  and Bank  employees  who are  employed at the
Effective  Time shall be given full credit for all prior service as employees of
Citizens or Bank provided,  however, that all such employees shall be treated as
newly hired Whitney's Bank employees  (i.e.,  prior service credit with Citizens
and Bank shall not be considered in determining  future benefits under Whitney's
Bank's  deferred  benefit  pension  plan) for all purposes of  Whitney's  Bank's
defined benefit pension plan.  Contemporaneously  with Citizens' delivery of its
Schedule of Exceptions, Whitney and Citizens shall supplement this

                                       30

                                Page 53 of 63

Agreement  respecting  the  post-Closing  roles of the  Citizens  directors  and
certain matters with respect to the Bank's executive officers.

         Section 6.  Conditions of Closing

         6.01.  Conditions of All Parties.   The  obligations  of  each  of  the
parties hereto to  consummate the Mergers are subject to the satisfaction of the
following conditions at or prior to the Closing:

                  (a)  Shareholder Approval.   This  Agreement  and  the Company
Merger Agreement shall have been duly approved by the shareholders of Citizens.

                  (b)  Effective   Registration   Statement.   The  Registration
Statement  shall  have  become  effective  prior  to the  mailing  of the  Proxy
Statement,  no stop  order  suspending  the  effectiveness  of the  Registration
Statement shall have been issued, and no proceedings for that purpose shall have
been instituted or, to the knowledge of any party,  shall be  contemplated,  and
Whitney shall have received all state securities laws permits and authorizations
necessary to consummate the transactions contemplated hereby.

                  (c) No Restraining  Action. No action or proceeding shall have
been  threatened  or  instituted  before a court or other  governmental  body to
restrain or prohibit the transactions  contemplated by the Merger  Agreements or
this  Agreement  or to obtain  damages or other  relief in  connection  with the
execution  of  such  agreements  or  the   consummation   of  the   transactions
contemplated  hereby or thereby;  and no  governmental  agency  shall have given
notice to any party hereto to the effect that  consummation of the  transactions
contemplated  by the Merger  Agreements  or this  Agreement  would  constitute a
violation  of any law or that it intends to  commence  proceedings  to  restrain
consummation of the Mergers.

                  (d)  Statutory   Requirements  and  Regulatory  Approval.  All
statutory   requirements   for  the  valid   consummation  of  the  transactions
contemplated  by the  Merger  Agreements  and this  Agreement  shall  have  been
fulfilled;  all appropriate  orders,  consents and approvals from all regulatory
agencies and other governmental  authorities whose order, consent or approval is
required by law for the  consummation of the  transactions  contemplated by this
Agreement and the Merger  Agreements shall have been received;  and the terms of
all requisite orders,  consents and approvals shall then permit the effectuation
of the Mergers  without  imposing any material  conditions  with respect thereto
except for any such conditions that are acceptable to Whitney.

                  (e) Tax Opinion.  Whitney and Citizens shall have received the
opinion of Arthur Andersen LLP, in form and substance reasonably satisfactory to
both of them,  as to certain tax aspects of the  Mergers,  including  an opinion
that the receipt of Whitney Common Stock by Citizens' shareholders will not be a
taxable event to such shareholders.

         6.02.  Additional   Conditions   of   Whitney   and  Acquisition.   The
obligations of Whitney, Acquisition and Whitney's Bank to consummate the Mergers
are also subject to the satisfaction  of  the following additional conditions at
or prior to the Closing:

                                       31

                                Page 54 of 63


<PAGE>




                  (a)   Representations,    Warranties   and   Covenants.    The
representations  and  warranties  of  Citizens  and the Bank  contained  in this
Agreement shall be true and correct in all material  respects,  individually and
in the aggregate,  on and as of the Closing Date, with the same effect as though
made on and as of such date,  except to the extent of changes  permitted  by the
terms of this  Agreement,  and each of  Citizens  and the Bank shall have in all
material  respects  performed  all  obligations  and complied with all covenants
required by this Agreement and the Merger Agreements to be performed or complied
with by it at or prior to the  Closing.  In  addition,  each of Citizens and the
Bank shall  have  delivered  to  Whitney,  Acquisition  and  Whitney's  Bank its
certificate  dated as of the  Closing  Date and  signed by its  chief  executive
officer and chief financial  officer to the effect that,  except as specified in
such  certificate,  such persons do not know, and have no reasonable  grounds to
know,  of any  material  failure or breach of any  representation,  warranty  or
covenant made by it in this Agreement.

                  (b) No Material Adverse Change.  There shall not have occurred
any material  adverse  change from the date of the Latest  Balance  Sheet to the
Closing Date in the  financial  condition,  results of operations or business of
Citizens'  consolidated  group;  provided,  however,  that (i) the incurrence by
Citizens of expenses (including fees and expenses of Robinson- Humphrey, Ernst &
Young LLP, Lippman,  Mahfouz & Martin, and Bracewell & Patterson,  L.L.P.),  and
payments to executive  officers or other  employees of Citizens or Bank pursuant
to agreements set forth on the Schedule of Exceptions and (ii) the occurrence of
an event  specifically  permitted  under  Section  5.07 or  otherwise  expressly
consented in writing by Whitney,  are expressly  deemed not to constitute such a
material adverse change.

                  (c)   Accountants'   Letters.   Whitney  shall  have  received
"comfort"  letters  from  Ernst &  Young,  independent  public  accountants  for
Citizens,  dated,  respectively,  within three (3) days prior to the date of the
Proxy  Statement  and  within  three  (3) days  prior to the  Closing  Date,  in
customary form for  transactions  of this sort and in substance  satisfactory to
Whitney.

                  (d)  Opinion of  Counsel.  Whitney  shall have  received  from
Bracewell & Patterson, L.L.P. special counsel to Citizens and Lippman, Mahfouz &
Martin,  opinions,  dated  as  of  the  Closing  Date,  in  form  and  substance
satisfactory  to Whitney.  In giving such opinions,  such counsel may rely as to
questions of fact upon  certificates  of one or more  officers of the members of
Citizens' consolidated group and governmental officials.

                  (e) Tax  Consequences of Mergers.  Whitney shall have received
satisfactory assurances from their independent accountants that the consummation
of the Mergers will not be a taxable event to Whitney and Whitney's Bank.

                  (f) Pooling of Interest. Prior to the expiration of the Review
Period and within three (3) days prior to the Closing Date,  Ernst & Young shall
have  rendered  an opinion to Whitney,  in form and  substance  satisfactory  to
Whitney,  to the effect that, based upon the facts and circumstances  then known
to Ernst & Young,  Whitney  will be  permitted  to account  for the Mergers as a
pooling of interests.  Neither  Whitney's  independent  accountants  nor the SEC
shall  have  taken  the  position  that the  transactions  contemplated  by this
Agreement  and the Merger  Agreements  do not qualify  for pooling of  interests
accounting treatment.

                                       32

                  (g)  Shareholder's   Commitment.  A  Shareholder's  Commitment
substantially  in the form specified on Exhibit 6.02(g) hereto (as  contemplated
by  Section  5.10)  shall  have been  executed  by each  person who serves as an
executive  officer or director of Citizens or the Bank or who owns 5% or more of
the Citizens Common Stock outstanding; and Whitney shall have received from each
such person a written confirmation dated not earlier than five days prior to the
Closing  Date to the  effect  that  each  representation  made in such  person's
Shareholder's Commitment is true and correct as of the date of such confirmation
and that such  person  has  complied  with all of his or her  covenants  therein
through the date of such confirmation.

                  (h) Regulatory  Action. No adverse  regulatory action shall be
pending or  threatened  against  any  member of  Citizens'  consolidated  group,
including (without limitation) any proposed amendment to any existing agreement,
memorandum,  letter, order or decree, formal or informal,  between any regulator
and any member of Citizens'  consolidated  group,  if such action would or could
impose any material  liability  on Whitney or interfere in any material  respect
with the conduct of the businesses of Whitney's consolidated group following the
Mergers.

                  (i) Average  Market  Price.  The Average  Market  Price of the
Whitney Common Stock as calculated in accordance  with Section 2.01 (but without
regard to the proviso contained therein) shall not be more than $35.50, provided
that Whitney may not terminate this Agreement  pursuant to this Section  6.02(i)
if Whitney has executed a definitive merger or other acquisition  agreement as a

to consummate the  Mergers are also subject to the satisfaction of the following
additional conditions at or prior to the Closing:

representations  and  warranties  of Whitney,  Acquisition  and  Whitney's  Bank
contained in this Agreement shall be true and correct in all material  respects,
individually and in the aggregate,  on the Closing Date, with the same effect as
though made on and as of such date, except to the extent of changes permitted by
the terms of this Agreement, and each of Whitney, Acquisition and Whitney's Bank
shall have in all material respects  performed all obligations and complied with
all  covenants  required  by this  Agreement  and the  Merger  Agreements  to be
performed or complied with by it at or prior to the Closing.  In addition,  each
of Whitney,  Acquisition and Whitney's Bank shall have delivered to Citizens and
the Bank its  certificate  dated as of the Closing  Date and signed by its chief
executive  officer and chief  financial  officer to the effect  that,  except as
specified in such certificate,  such persons do not know, and have no reasonable
grounds  to know,  of any  material  failure  or breach  of any  representation,
warranty or covenant made by it in this Agreement.

                  (b)  Opinion of Counsel.  Citizens  shall have  received  from
Milling,  Benson,  Woodward,  Hillyer,  Pierson & Miller,  counsel for  Whitney,

received letters from The Robinson-Humphrey  Company, Inc. dated the date of the
mailing of the Proxy Statement to shareholders of Citizens and dated the date of
the meeting of the shareholders of Citizens,  in each case in form and substance
satisfactory to Citizens,  confirming such financial  advisor's prior opinion to
the Board of  Directors of Citizens to the effect that the  consideration  to be
paid in the Merger is fair to its shareholders from a financial point of view.

                  (d)  Tax Opinion.  Citizens shall have received the opinion of
Bracewell & Patterson, L.L.P.  as  to  certain  tax  aspects of the transactions
contemplated by this Agreement  and the Merger Agreements, in form and substance
satisfactory to Citizens.

                  (e) No Material Adverse Change.  There shall not have occurred
any material adverse change from Whitney's Latest Balance Sheet to the Effective
Date in the financial condition,  results of operations or business of Whitney's
consolidated group taken as a whole.

                  (f) Average  Market  Price.  The Average  Market  Price of the
Whitney Common Stock as calculated in accordance  with Section 2.01 (but without
regard to the proviso contained therein) shall not be less than $25.50.

         6.04.  Waiver of  Conditions.  Any  condition to a party's  obligations
hereunder may be waived by that party,  other than the  conditions  specified in
subparagraphs  (a),  (b) and (d) of  subsection  6.01  hereof and the  condition
specified in subparagraph  (c) of subsection  6.03 hereof.  The failure to waive
any condition hereunder shall not be deemed a breach of subsection 5.02 hereof.

         Section 7.  Termination

         7.01.  Termination.  This  Agreement  and  the Merger Agreements may be
terminated  and the Mergers contemplated herein abandoned at any time before the
Effective  Time,  whether  before  or  after  approval  by  the  shareholders of
Citizens:

                  (a)  Mutual Consent.  By  the  mutual consent of the Boards of
Directors of Whitney and Citizens.

                  (b) Breach.  By the Board of  Directors  of either  Whitney or
Citizens in the event of a breach by any member of the consolidated group of the
other of them of any  representation or warranty  contained in this Agreement or
of any covenant contained in this Agreement,  which in either case cannot be, or
has not been,  cured within 15 days after written notice of such breach is given
to the entity  committing  such breach,  provided  that the right to effect such
cure shall not extend beyond the date set forth in subparagraph (c) below.

<PAGE>



                  (c)  Abandonment.  By the Board of Directors of either Whitney
or Citizens if (i) all  conditions to Closing  required by Section 6 hereof have
not been met by or waived by Whitney or Citizens by June 30,  1996,  or (ii) any
such  condition  cannot be met by June 30,  1996 and has not been waived by each
party in whose favor such  condition  inures,  or (iii) if the Mergers  have not
been  consummated by June 30, 1996,  provided that the failure to consummate the
transactions  contemplated  hereby  is not  caused  by  the  party  electing  to
terminate pursuant to this clause (iii).

                  (d)  Dissenting  Shareholders.  By  Whitney,  if the number of
shares of Citizens Common Stock as to which the holders thereof are, at the time
of the Closing,  legally entitled to assert dissenting  shareholders rights plus
the  number of such  shares as to which the  holders  thereof  are  entitled  to
receive cash payments in lieu of fractional shares exceeds that number of shares
of Citizens Common Stock that would preclude pooling of interests accounting for
the Mergers.

                  (e)  Shareholder Vote.  By  Whitney  or  Acquisition  if  this
Agreement  or  the  Company  Merger  fails  to receive the requisite vote at any
meeting of Citizens shareholders called for the purpose of voting thereon.

                  (f) Citizens Recommendation.  By Whitney or Acquisition if the
Board of  Directors  of  Citizens  (A) shall  withdraw,  modify  or  change  its
recommendation  to its  shareholders  of this  Agreement or the Mergers or shall
have  resolved to do any of the  foregoing;  (B) shall have  recommended  to the
shareholders of Citizens (or in the case of (iii) approved) any of the following
(being  referred  to herein as an  "Acquisition  Transaction")  (i) any  merger,
consolidation, share exchange, business combination or other similar transaction
(other than the  transactions  contemplated by this  Agreement);  (ii) any sale,
lease,  transfer or other  disposition of all or substantially all of the assets
of any member of Citizens' consolidated group; or (iii) any acquisition,  by any
person  or group,  of the  beneficial  ownership  of 15% or more of any class of
Citizens  capital stock; or (C) shall have made any  announcement of a proposal,
plan or intention to do any of the  foregoing or any  agreement to engage in any
of the foregoing.

                  (g)  Prior to Notification Date.   By Whitney by delivery of a
notice to terminate this Agreement pursuant to Section 5.01(b).

                  (h) Acquisition Transaction. By Citizens in the event Citizens
receives a written  offer with  respect to an  Acquisition  Transaction  and the
Board of Directors of Citizens determines in good faith, after consultation with
its financial  advisors and counsel,  that such Acquisition  Transaction is more
favorable to Citizens'  shareholders than the transactions  contemplated by this
Agreement.

         7.02.  Effect  of  Termination;  Survival.  Upon  termination  of  this
Agreement  pursuant  to  this  Section  7,  the  Merger  Agreements  shall  also
terminate,  and this Agreement and the Merger Agreements shall be void and of no
effect,  and there  shall be no  liability  by reason of this  Agreement  or the
Merger Agreements, or the termination thereof, on the part of any party or their
respective directors, officers, employees, agents or shareholders except for any
liability

of  a  party  hereto   arising  out  of  (i)  an   intentional   breach  of  any
representation,  warranty  or covenant  in this  Agreement  prior to the date of
termination,  except if such  breach was  required by law or by any bank or bank
holding  company  regulatory  authority  or (ii) a breach of any  covenant  that
survives  pursuant to the following  sentence.  The following  provisions  shall
survive any  termination  of this  Agreement:  the last  sentence of  subsection
5.01(a); subsection 7.02; subsection 7.03 and Section 8.

         7.03.  Termination Fee.   If this  Agreement  is terminated pursuant to

         8.07.  Choice of Law.  The  validity of this  Agreement  and the Merger
Agreements,  the construction of their terms and the determination of the rights

contemplated  hereby and thereby by the shareholders of the parties hereto. This
Agreement  and any exhibit or schedule to this  Agreement  may be amended at any
time and, as amended, restated by the chief executive officers of the respective
parties (or their  respective  designees)  without the necessity for approval by
their respective Boards of Directors or shareholders,  to correct  typographical

a  representation  or  warranty  or  covenant by the other party shall be not to
close  the  transactions   described  herein  if  such  breach  results  in  the
nonsatisfaction of a condition set forth in Section 6 hereof; provided, however,
that the  foregoing  shall  not be  deemed  to be a waiver  of any  claim for an
intentional breach of a representation, warranty or covenant or for fraud except
if such  breach  is  required  by law or by any  bank or  bank  holding  company
regulatory  authority;  it being  understood  that a  disclosure  in any closing
certificate  provided in accordance with  subparagraph (a) of subsection 6.02 or
subparagraph  (a) of  subsection  6.03  hereof  concerning  an  inaccuracy  of a
representation  or warranty  shall not of itself be deemed to be an  intentional
breach of such  representation  or  warranty.  The  covenants of the parties set
forth herein shall survive the Effective Time in accordance with their terms.
