payment therefore) and options to purchase Citizens Common Stock will be
converted into and represent the right to receive a number of shares of Crestar
Common Stock or options to purchase Crestar Common Stock determined by the
Exchange Ratio, subject to adjustment as set forth in the Agreement. Cash will
be paid in lieu of fractional shares of Crestar Common Stock. At the Effective
Time of the Holding Company Merger, each share of Citizens Common Stock held by
Crestar, excluding shares held in a fiduciary capacity, shall be canceled,
retired and cease to exist, and no exchange or payment shall be made with
respect thereto. Crestar does not directly hold any shares of Citizens Common
Stock.
 
     Crestar expects to merge Citizens Bank into Crestar Bank by the end of the
first quarter of 1997.
 
THE EXCHANGE RATIO
 
     In the Holding Company Merger, each share of Citizens Common Stock will be
converted into 0.835 shares of Crestar Common Stock. If the Average Closing
Price (as defined below) of Crestar Common Stock is $48 or less during the 10-
trading day period prior to the 10th day before the Closing Date, Citizens may
terminate the Agreement. In such case, however, Crestar can extend the Closing
Date for 15 trading days, and during the first 10 trading days of the extended
period a new Average Closing Price for Crestar Common Stock will be determined.
If the new Average Closing Price in the extended period is more than $48, no
termination occurs and the Agreement remains in effect. If the new Average
Closing Price is $48 or less, Crestar may increase the consideration to be
received by Citizens' shareholders by adjusting the Exchange Ratio to equal a
number equal to the quotient obtained by dividing $40.08 by the new Average
Closing Price; if Crestar elects not to do this, the Agreement terminates.
In no event is the adjusted Exchange Ratio to be less than 0.835 shares of
Crestar Common Stock. The "Average Closing Price" is the average of the closing
sales price

                                       4

<PAGE>

of Crestar Common Stock as reported on the consolidated tape of the New York
Stock Exchange for each of the 10-day trading periods ending on the 10th day
prior to the Closing Date, and the new "Average Closing Price" is the same
average for 10 trading days in the extended period.

 
     Outstanding options to purchase Citizens Common Stock that were granted
under Citizens' 1986 Stock Incentive Plan and 1988 Stock Option Plan (the
"Citizens Options") will be converted, based on the Exchange Ratio, into options
to acquire shares of Crestar Common Stock ("Crestar Options"). The exercise
price per share of Crestar Common Stock under a Crestar Option will be equal to
the exercise price per share of Citizens Common Stock under the Citizens Option
divided by the Exchange Ratio. The number of shares of Crestar Common Stock
subject to a Crestar Option will be equal to the number of shares of Citizens
Common Stock subject to the Citizens Option multiplied by the Exchange Ratio.
Other terms of a Crestar Option will be the same as the terms of the Citizens
Option.
 
REASONS FOR THE HOLDING COMPANY MERGER; RECOMMENDATIONS OF THE CRESTAR BOARD AND
THE CITIZENS BOARD
 
     CRESTAR. The Crestar Board believes that the terms of the Holding Company
Merger and the Agreement are advisable and are fair to, and in the best
interests of, Crestar and its shareholders and has unanimously adopted the
Agreement. In considering the terms and conditions of the Holding Company
Merger, the Crestar Board considered, among other things, the financial terms of
the Holding Company Merger, its effect on future earnings, the strategic value
of enhancing Crestar's franchise in Maryland and the Greater Washington Region,
and the opinion of its financial advisor, Morgan Stanley & Co. Incorporated
("Morgan Stanley"), that as of the date of its opinion the Exchange Ratio
pursuant to the Agreement is fair from a financial point of view to Crestar. The
Board believes the Holding Company Merger will provide Crestar with a
competitive advantage by increasing future earnings, expanding distribution of
products, and building market share -- all without sacrificing asset quality.
The Crestar Board also considered that Crestar shareholders would incur modest
dilution in earnings per share in the first year following the Holding Company
Merger.
 
     CITIZENS. The Citizens Board believes that the terms of the Holding Company
Merger and the Agreement are advisable and are fair to, and in the best
interests of, Citizens and its shareholders and has unanimously adopted the
Agreement. In considering the terms and conditions of the Holding Company
Merger, the Citizens Board considered, among other things: the financial terms
of the Holding Company Merger; the fact that the Holding Company Merger would
qualify as a tax-free reorganization; the financial condition and history of
performance of Crestar; the advantage of risk diversification associated with
ownership in an institution operating in a broader geographic area; the opinion
of its financial advisor, Keefe, Bruyette & Woods, Inc. ("Keefe Bruyette"), that
the consideration to be received in the Holding Company Merger is fair to the
holders of Citizens Common Stock from a financial point of view; and the
operational and competitive benefits of the Holding Company Merger. The Citizens
Board also considered that the historical dividends per share and net income per
share of the Crestar Common Stock to be received by the holders of Citizens
Common Stock, after giving effect to the Exchange Ratio, represent a substantial
increase in the historical dividends per share and net income per share of
Citizens Common Stock, although there can be no assurance that pro forma amounts
are indicative of future dividends or income per share of Crestar Common Stock.
See "The Holding Company Merger -- Background to the Holding Company Merger,"
" -- Reasons for the Holding Company Merger; Recommendations of the Crestar
Board and the Citizens Board," and " -- Opinions of Financial Advisors."
 
 THE CITIZENS BOARD UNANIMOUSLY RECOMMENDS THAT THE HOLDERS OF CITIZENS COMMON
           STOCK VOTE TO APPROVE THE PROPOSED HOLDING COMPANY MERGER.
 
OPINIONS OF FINANCIAL ADVISORS
 
     CRESTAR. Crestar has received the opinion of Morgan Stanley that the
Exchange Ratio is fair from a financial point of view to Crestar. Morgan
Stanley's opinion is directed only to the Exchange Ratio and does not constitute
a recommendation to any holders of Crestar Common Stock as to how such holders
should vote at the Crestar Special Meeting or as to any other matter. Crestar
has agreed to pay Morgan Stanley an advisory fee of between $100,000 and
$150,000, payable if the Holding Company Merger is not consummated, and a
transaction fee of $3.5 million, payable upon consummation of the Holding
Company Merger. Any advisory fee paid will be credited against the transaction
fee. For additional information concerning Morgan Stanley and its opinion, see
"The Holding Company Merger -- Opinions of Financial Advisors." The opinion of
such firm, which sets forth the assumptions made, matters considered and limits
on the review undertaken, is attached as Annex III to this Joint Proxy
Statement/Prospectus.

     CITIZENS. Citizens has received the opinion of Keefe Bruyette that the
Exchange Ratio is fair to the holders of Citizens Common Stock from a financial
point of view. Keefe Bruyette's opinion is directed only to the Exchange Ratio
and does not constitute a recommendation to any holders of Citizens Common Stock
as to how such holders should vote at the Citizens Special Meeting or as to any
other matter. Citizens paid Keefe Bruyette a cash fee of $100,000 when the
Merger Agreement was signed and $200,000 when the Proxy Statement/Prospectus was
mailed, and will pay Keefe Bruyette $390,000 upon consummation of the Holding
Company Merger. For additional information concerning Keefe Bruyette and its
opinion, see "The Holding Company Merger -- Opinions of Financial Advisors." The
opinion of such firm, which sets forth the assumptions made, matters considered
and limits on the review undertaken, is attached as Annex IV to this Joint Proxy
Statement/Prospectus.
 
NO DISSENTER'S RIGHTS
 
     Holders of Citizens Common Stock entitled to vote on the Agreement and the
related Holding Company Plan of Merger do not have dissenter's rights in
accordance with Maryland General Corporation Law.
 
CONDITIONS TO CONSUMMATION
 
     The Holding Company Merger is to be accomplished by the statutory merger of
Acquisition into Citizens and is contingent upon approvals of the Board of
Governors of the Federal Reserve System (the "Federal Reserve Board"), the
Division of Financial Regulation of the Maryland Department of Labor, Licensing
and Regulation (the "Maryland Department") and the Bureau of Financial
Institutions of the State Corporation Commission of Virginia (the "SCC"), which
approvals have been applied for and are expected to be received. The Holding
Company Merger is also subject to other usual conditions, including receipt by
Crestar and Citizens of the legal opinions of Semmes, Bowen & Semmes, counsel to
Citizens, and of Hunton & Williams, counsel to Crestar, that the Holding Company
Merger and the Citizens/Crestar Merger together will constitute a tax-free
reorganization under Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code") and receipt by Crestar of a letter from KPMG Peat Marwick
LLP stating that the Transaction may be accounted for under the pooling-of-
interests accounting method. See "The Holding Company Merger -- Conditions to
Consummation of the Holding Company Merger."
 
BUSINESS OF CRESTAR AND CITIZENS PENDING THE HOLDING COMPANY MERGER
 
     Citizens has agreed to carry on its operations only in the ordinary course
of business and not to take certain actions relating to the operation of its
business pending consummation of the Holding Company Merger without notice to or
the approval of Crestar, including the payment of cash dividends other than the
regular quarterly cash dividends consistent with its practice in effect in the
second quarter of 1996. Crestar has agreed that it will conduct its operations
only in the ordinary course of business consistent with past practice and not to
take certain actions. See "The Holding Company Merger -- Business of Crestar and
Citizens Pending the Holding Company Merger."
 
WAIVER AND AMENDMENT; TERMINATION
 
     Crestar and Citizens may amend or modify the Agreement at any time, except
that, after the vote by the shareholders of Crestar and Citizens, no such
amendment or modification may be made which reduces or changes the form and
amount of consideration payable pursuant to the Agreement without further
shareholder approval. If at any time before the Effective Time of the Holding
Company Merger, a material term of the Agreement or Holding Company Plan of
Merger is amended, the Citizens Board will postpone or reschedule the Citizens
Special Meeting (or, if necessary, call additional shareholder meetings), to
vote on the Agreement and Holding Company Plan of Merger, as amended, and
resolicit proxies for use at such meeting.
 
     Crestar and Citizens each has the right, acting unilaterally, to terminate
the Agreement should the Holding Company Merger not be consummated by June 30,
1997 and prior to that time upon the occurrence of certain events. See "The
Holding Company Merger -- Waiver and Amendment; Termination."
 
INTERESTS AND CONFLICTS OF INTERESTS OF CERTAIN PERSONS IN THE HOLDING COMPANY
MERGER

     Certain members of Citizens' management and the Citizens Board have
interests and conflicts of interest in the Holding Company Merger in addition to
their interests as shareholders of Citizens generally. These include, among
other things, provisions in the Agreement requiring Crestar to honor existing
employment and severance agreements with Jeffrey R. Springer, Richard C.
Bandiere, Raymond L. Gazelle, Jr. and Gary N. Geisel, the offering to five to
eight members of the
 
                                       6
 
<PAGE>

Citizens Board of a position on Crestar Bank's GWR or Maryland advisory board,
increasing the number of Crestar's and Crestar Bank's Board of Directors by two
and appointing Alfred H. Smith, Jr. and Jeffrey R. Springer to fill the
resulting vacancies, indemnification for Citizens directors and officers, and
eligibility for certain Crestar employee benefits. Under Mr. Springer's
agreement, he will receive a lump sum payment of approximately $1,483,040, and
Messrs. Bandiere, Gazelle and Geisel will receive cash severance payments over
30 months of $680,000, $595,000 and $672,500, respectively. Each of the five to
eight members of the Citizens Board named to a Crestar advisory board will be
paid retainer and meeting fees of up to approximately $5,000 per year. As
directors of Crestar, Messrs. Smith and Springer will be paid an annual retainer
(currently $18,000) and $1,000 per meeting attended, and an additional $500 for
a second meeting on the same day. Each also will participate in the Crestar
Directors' Equity Program, which annually awards Crestar Common Stock with a
value of $8,000 to directors as part of their compensation.

 
     For additional information concerning the employment agreements, see "The
Holding Company Merger -- Interests and Conflicts of Interest of Certain Persons
in the Holding Company Merger." All Citizens Options are issued pursuant to
plans previously approved by the shareholders of Citizens.
 
RESALE OF CRESTAR COMMON STOCK
 
     Shares of Crestar Common Stock received in the Holding Company Merger will
be freely transferable by the holders thereof, except for those shares held by
those holders who may be deemed to be "affiliates" of Citizens or Crestar under
applicable federal securities laws. See "Resale of Crestar Common Stock."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTION
 
     The Holding Company Merger and the Citizens/Crestar Merger are intended to
be treated as one transaction qualifying as a tax-free "reorganization" as
defined in Section 368(a) of the Code. (The Holding Company Merger and the
Citizens/Crestar Merger are sometimes referred to together as the "Merger".)
Crestar has received the opinion of Hunton & Williams, and Citizens has received
the opinion of Semmes, Bowen & Semmes, that the Merger will qualify as a
"reorganization" as defined in Section 368(a) of the Code. Citizens also has
received the opinion of Semmes, Bowen & Semmes that Citizens shareholders will
not recognize gain or loss on the exchange of Citizens Common Stock for Crestar
Common Stock (including the associated Rights), except with respect to cash paid
in lieu of fractional shares. A condition to consummation of the Merger is the
receipt by Crestar from Hunton & Williams and by Citizens from Semmes, Bowen &
Semmes of opinions as to the qualification of the Merger as a reorganization and
certain other federal income tax consequences of the Merger. See "The Holding
Company Merger -- Certain Federal Income Tax Consequences."
 
EFFECTIVE TIME
 
     The Holding Company Merger will become effective on the date and time
specified in the Articles of Merger for the Holding Company Merger to be filed
with the State Department of Assessments and Taxation of Maryland ("SDAT") and
the State Corporation Commission of Virginia. The Effective Time of the Holding
Company Merger is to be not later than June 30, 1997, and is expected to occur
by December 31, 1996.
 
STOCK OPTION AGREEMENT
 
     Crestar and Citizens have entered into a Stock Option Agreement, dated as
of September 15, 1996 (the "Option Agreement"), pursuant to which Citizens
issued to Crestar an option (the "Option") to purchase up to 3,012,000 shares of
Citizens Common Stock at a purchase price of $40.00 per share. The Option may be
exercised in whole or in part, at any time or from time to time if a Purchase
Event (as defined therein) shall have occurred and be continuing. The Option
Agreement provides that to the extent that it shall have not been exercised, the
Option shall terminate (i) on the Effective Date of the Holding Company Merger;
(ii) upon termination of the Agreement in accordance with the provisions thereof
(other than a termination resulting from a willful breach by Citizens of certain
specified covenants contained therein or, following the occurrence of a Purchase
Event (as defined therein), failure of Citizens shareholders to approve the
Agreement by the vote required under applicable law or under Citizens' charter);
or (iii) 12 months after termination of the Agreement due to a willful breach by
Citizens of certain specified covenants contained therein or, following the
occurrence of a Purchase Event (as defined therein), failure of Citizens
shareholders to approve the Holding Company Merger by the vote required under
applicable law or under Citizens' charter. The Option Agreement is attached
hereto as Annex II. See also "The Holding Company Merger -- Stock Option
Agreement."

an assumed Exchange Ratio of 0.835.
 
COMPARATIVE PER SHARE DATA
 
     The following table presents historical and pro forma per share data for
Crestar, and historical and equivalent pro forma per share data for Citizens.
The pro forma combined per Crestar common share amounts give effect to the
Exchange Ratio of 0.835 shares of Crestar Common Stock for each share of
Citizens Common Stock. The equivalent pro forma per Citizens common share
amounts allow comparison of historical information regarding one share of
Citizens Common Stock to the corresponding data regarding what one share of
Citizens Common Stock will equate to in the combined corporation; such amounts
are computed by multiplying the pro forma combined per Crestar common share
amounts by the Exchange Ratio. The following table is based on the assumption
that all issued and outstanding shares of Citizens Common Stock are converted
into shares of Crestar Common Stock. The Holding Company Merger is reflected
under the pooling-of-interests method of accounting and pro forma information is
derived accordingly.
 
     The per share data included in the following table should be read in
conjunction with the consolidated financial statements of Crestar and the
consolidated financial statements of Citizens incorporated by reference herein
and the notes accompanying all such financial statements. The data presented
below are not necessarily indicative of the results of operations which would
have been obtained if the Holding Company Merger had been consummated in the
past or which may be obtainable in the future.

(1) Pro forma combined book value per share and cash dividends declared per
    share for Crestar and Citizens do not reflect exercise of options to acquire
    shares of Citizens Common Stock. Options to acquire 674,250 Citizens common
    shares at an average price per share of $22.81 were outstanding at September
    30, 1996. Assumed exercise of these options does not have a significant
    impact upon the combined stockholders' equity of Crestar and Citizens or the
    pro forma combined cash dividends declared per share.

 

(2) Pro forma combined book value per Crestar common share at September 30, 1996
    represents combined common shareholders' equity amounts, less an amount
    representing the after-tax impact of material, non-recurring adjustments
    expected to be recorded in conjunction with the Holding Company Merger,
    divided by pro forma combined period-end common shares outstanding. Certain
    material, non-recurring adjustments of approximately $42 million, on a
    pre-tax basis, will be recorded in conjunction with the Holding Company
    Merger. These adjustments include approximately $9 million for settlement of
    obligations under existing employment contracts, severance pay for
    involuntary terminations, and related employee benefit costs, approximately
    $18 million associated with branch closings and consolidations, and
    approximately $15 million of expenses related to consummating the Holding
    Company Merger, including signage and customer service expenses. On an
    after-tax basis, these non-recurring adjustments are approximately $28
    million.

 
(3) Pro forma combined dividends declared per Crestar common share represent
    historical dividends per share declared by Crestar.
 
(4) Pro forma combined net income per Crestar common share represents combined
    net income available to common shareholders, divided by pro forma combined
    average primary common shares outstanding.
 
SELECTED FINANCIAL DATA
 
     The following consolidated financial data of Crestar and consolidated
financial data of Citizens is qualified in its entirety by the information

by reference. Interim financial results for Crestar, in the opinion of Crestar
management, reflect all adjustments necessary for a fair presentation of the
results of operations, including adjustments related to completed acquisitions.
All such adjustments are of a normal nature. Interim financial results for
Citizens, in the opinion of Citizens management, reflect all adjustments
necessary for a fair presentation of the results of operations. The results of

Merger is reflected under the pooling-of-interests method of accounting and pro
forma information is derived accordingly. See "Incorporation of Certain
Information by Reference."

    in conjunction with the Holding Company Merger. These adjustments include
    approximately $9 million for settlement of obligations under existing
    employment contracts, severance pay for involuntary terminations, and
    related employee benefit costs; approximately $18 million associated with
    branch closings and consolidations; and approximately $15 million of
    expenses related to consummating the Holding Company Merger, including
    signage and customer service expenses. On an after-tax basis, these
    non-recurring adjustments approximately $28 million.

 
(6) Nonperforming assets include nonaccrual loans, restructured loans and
    foreclosed properties.
 
(7) Net interest margin is calculated on a taxable equivalent basis, using a tax
    rate of 35% for 1996, 1995, 1994 and 1993 and 34% for 1992 and 1991.
 
(8) Weighted average shares outstanding for Crestar is composed of the weighted
    average number of common shares outstanding during the period, including
    average common equivalent shares attributable to dilutive stock options.
    Weighted average shares outstanding for Citizens is composed of the weighted
    average number of common shares outstanding during the period; the dilutive
    effect of Citizens stock options was not material for any period presented.

CRESTAR SPECIAL MEETING


     Each copy of this Joint Proxy Statement/Prospectus mailed to holders of
Crestar Common Stock is accompanied by a proxy appointment card furnished in
connection with Crestar's solicitation of proxies for use at the Crestar Special
Meeting. The Crestar Special Meeting is scheduled to be held on December 30,
1996, at 919 East Main Street, Richmond, Virginia. Only holders of record of
Crestar Common Stock at the close of business on November 1, 1996, are entitled
to receive notice of and to vote at the Crestar Special Meeting.

 
     At the Crestar Special Meeting, shareholders will have the opportunity, in
accordance with the shareholder approval policy of the NYSE, to consider and
vote on a proposal to approve the issuance of shares of Crestar Common Stock and
options to purchase such Common Stock pursuant to the terms of the Agreement.
The NYSE requires, as a prerequisite to the listing of such shares on the NYSE,
shareholder approval of such issuance because the shares and the shares subject
to options will represent more than 20% of the shares of Crestar Common Stock
outstanding. Based on the Exchange Ratio, approximately 13,200,000 shares of
Crestar Common Stock will be required to acquire outstanding shares of Citizens
Common Stock in the Holding Company Merger and for Crestar options to replace
existing options covering shares of Citizens Common Stock. The Crestar shares to
be issued and the Crestar shares to become subject to the replacement options
will represent approximately 31% of shares of Crestar Common Stock outstanding
at the Crestar Record Date.
 
     HOLDERS OF CRESTAR COMMON STOCK ARE REQUESTED TO COMPLETE, DATE AND SIGN
THE ACCOMPANYING PROXY APPOINTMENT CARD AND RETURN IT PROMPTLY TO CRESTAR IN THE

appointment may revoke it at any time before it is voted by attending and voting
in person at the Crestar Special Meeting or by giving written notice of
revocation or submitting a signed proxy appointment bearing a later date to
Crestar, Attention: Corporate Secretary, provided such notice or proxy
appointment is actually received by Crestar prior to the vote of shareholders. A
proxy appointment will not be revoked by the death or incapacity of the
shareholder executing it unless, before the shares are voted, notice of such
death or supervening incapacity is filed with the Corporate Secretary or other
person authorized to tabulate the votes on behalf of Crestar. The shares of
Crestar Common Stock represented by properly executed proxy appointments
received in time for the Crestar Special Meeting will be voted for approval of
the issuance of the shares of Crestar Common Stock pursuant to the terms of the
Agreement. If any other matters are properly presented for consideration at the
Crestar Special Meeting or any adjournment, the persons named in the Crestar
proxy appointment card enclosed herewith will have discretionary authority to
vote on such matters in accordance with their best judgment. Crestar is unaware
of any matter to be presented at the Crestar Special Meeting other than the
proposal for the issuance of the shares of Crestar Common Stock pursuant to the
terms of the Agreement.
 
     The cost of soliciting proxies from holders of Crestar Common Stock will be
borne by Crestar. Such solicitation will be made by mail but also may be made by
telephone or in person by the directors, officers or employees of Crestar (who
will receive no additional compensation for doing so). In addition to such
solicitations, D. F. King & Co., Inc., a proxy solicitation firm, will assist
Crestar in soliciting proxies for the Crestar Special Meeting and will be paid a
fee of $10,000, plus out-of-pocket expenses. Crestar will make arrangements with

notice of such death or incapacity is filed with the Secretary or other person
responsible for tabulating votes on behalf of Citizens. The shares of Citizens
Common Stock represented by properly executed proxy appointments received at or
prior to the Citizens Special Meeting and not subsequently revoked will be voted
as directed by the shareholders submitting such appointments. If instructions

the Citizens Board considered, among other things, the opinion of Keefe Bruyette
that the Exchange Ratio was fair to Citizens shareholders from a financial point
of view.
 
                           THE HOLDING COMPANY MERGER
 
     The detailed terms of the Holding Company Merger are contained in the
Agreement and Plan of Reorganization, attached as Annex I to this Joint Proxy
Statement/Prospectus. The following discussion describes the material features
of the proposed Holding Company Merger and the terms of the Agreement. This
description is qualified by reference to the Agreement which is incorporated by
reference herein.
 
BACKGROUND OF THE HOLDING COMPANY MERGER
 
     Since its entry into the Greater Washington Region ("GWR") in 1985 by the
acquisition of NS&T Bankshares in the District of Columbia and the acquisition
of Bethesda Bancorporation in Maryland the following year, Crestar has sought to
increase its presence in GWR and, more recently, Baltimore, by a series of
strategic thrift and bank acquisitions. Since 1985, Crestar has acquired 24
banks and thrift institutions in GWR and Maryland. In 1995, Crestar acquired
branches of Chase Manhattan Bank of Maryland and Loyola Federal Savings Bank in
Baltimore. In 1996, Crestar acquired branches of Mellon Bank MD.
 
     Crestar is an active acquirer of bank holding companies, commercial banks,
and thrifts, and a number of its officers have as one of their principal duties
contacting potential acquisition candidates. Since January 1, 1996, Crestar has
made no firm offer to acquire a financial institution other than Citizens. Since
January 1, 1996, Citizens has had no contact with or received any firm offer
from any financial institution other than Crestar, except that one financial
institution informally contacted Citizens to express interest in a possible
affiliation. Citizens has not had an active acquisition program and has had no
contact or made any firm offer with respect to acquiring any other financial
institution since January 1, 1996.
 
     Notwithstanding the strategic acquisitions mentioned above , Crestar's
coverage of GWR in Montgomery and Prince George's counties, Maryland, was
incomplete and, for a number of years beginning in 1993, Crestar has carried on
friendly, sporadic and inconclusive discussions with Citizens' management with
respect to a possible acquisition. Citizens' management's position was that it
was willing to discuss affiliation with any potential acquiror, but its
discussions with Crestar were always inconclusive until a series of meetings
begun in July of this year.
 
     At a social outing involving C. Garland Hagen, head of Crestar's investment
bank; William C. Harris, head of Crestar's GWR and Maryland operations; and
Jeffrey R. Springer, President of Citizens, the determination was made to
explore the benefits of a potential merger between Citizens and Crestar. The
determination was reached by Messrs. Hagen and Springer to informally exchange
information about the two companies. Following this social meeting, Mr. Springer
informed Mr. Harris by telephone that he had been authorized by Citizens'
Chairman Alfred H. Smith, Jr. to explore merger possibilities at a very high
level (involving only a few people from each company), and that Mr. Smith had
approved the exchange of information and further discussions. Thereafter,
Crestar notified Citizens of the type of information it would need to conduct
preliminary due diligence and, following receipt of this information, meetings
were held in August in Baltimore to discuss and clarify the information and also
to give the opportunity to Crestar to provide Citizens with its business plan
and ideas for combining the Crestar and Citizens organizations.
 
     Crestar engaged Morgan Stanley on August 22, 1996, as its financial advisor
to assist in the negotiations and to provide a fairness opinion, and Citizens
engaged Keefe Bruyette on September 9, 1996, to provide a fairness opinion.
 
     On August 22 and 23, 1996, Crestar's Policy Committee, comprising seven top
officers of Crestar, reviewed the negotiations to date and the Crestar mergers
and acquisitions staff's preliminary analysis and evaluation of Citizens, and
authorized Mr. Hagen to continue discussions. On Tuesday, August 27, 1996, at a
meeting in Baltimore, further information was exchanged, including information
regarding credit quality and pro forma projections for the combined enterprise,
information concerning Crestar's benefit plans and human resources practices,
the proposed due diligence process, and a possible deal structure. On Friday,
September 6, 1996, Crestar's Policy Committee met to discuss deal pricing and
structure, with Morgan

                                       16

Stanley's representatives participating by telephone. Late in the day, in a
series of telephone calls between Crestar's and Citizens' managements, a fixed
exchange ratio and the "walk-away" provisions were agreed to subject to
negotiation of the definitive agreement, Crestar's conduct of due diligence, and
approval by both boards of directors.
 
     The definitive agreement was negotiated during the ensuing week in
negotiations participated in by top management officials of both corporations,
outside counsel, and financial advisors, resulting in an agreement which was
preliminarily approved by both boards of directors on Thursday, September 12,
1996, following receipt of fairness opinions from their respective financial
advisors and subject to Crestar's satisfactory completion of due diligence
during the ensuing weekend at Citizens locations.
 

     The Crestar Board met on Sunday, September 15, 1996, at 5:00 p.m. and the
Citizens Board met one hour later at 6:00 p.m. The Crestar Board received a
favorable report on the due diligence investigation, and following receipt of
favorable opinions from their respective financial advisors, both boards
approved unanimously the Agreement and related documents.

 
REASONS FOR THE HOLDING COMPANY MERGER; RECOMMENDATIONS OF THE CRESTAR BOARD AND
THE CITIZENS BOARD
 
     CRESTAR. The Crestar Board believes that the terms of the Holding Company
Merger and the Agreement are advisable and are fair to, and in the best
interests of, Crestar and its shareholders and has unanimously adopted the
Agreement. In considering the terms and conditions of the Holding Company
Merger, the Crestar Board considered, the financial terms of the Holding Company
Merger, its effect on future earnings, the strategic value of enhancing
Crestar's franchise in Maryland and the Greater Washington Region, and the
opinion of Morgan Stanley that as of the date of such opinion that the Exchange
Ratio pursuant to the Agreement is fair from a financial point of view to
Crestar. The Board believes the Holding Company Merger will provide Crestar with
a competitive advantage by increasing future earnings, expanding distribution of
products, and building market share -- all without sacrificing asset quality.
The Crestar Board also considered that Crestar shareholders would incur modest
dilution in earnings per share in the first year following the Holding Company
Merger. Although the financial terms of the Holding Company Merger were the most
important factor the Crestar Board considered, the Crestar Board is unable to
assign any relative or specific weight to the factors it considered.

     The Crestar Board believes that issuance of Crestar Common Stock pursuant
to the Agreement is advisable and is fair to, and in the best interests of,
Crestar and its shareholders. The Crestar Board unanimously recommends that
Crestar shareholders vote for the issuance of the Crestar shares pursuant to the
Agreement.
 
     CITIZENS. The Citizens Board believes that the terms of the Holding Company
Merger and the Agreement are advisable and are fair to, and in the best
interests of, Citizens and its shareholders. As explained below, this conclusion
is supported by the opinion of its independent financial advisor that the
consideration to be received in the Holding Company Merger is fair to Citizens
shareholders from a financial point of view. In considering the terms and
conditions of the Agreement, the Citizens Board considered a number of factors.
Although the financial terms of the Holding Company Merger were the most
important factor the Citizens Board considered, the Citizens Board is unable to
assign any relative or specific weight to the factors it considered. The
material factors considered were:
 
     (i) The Financial Terms and Structure of the Holding Company Merger. The
Citizens Board was of the view that, based on historical and anticipated trading
ranges for Crestar Common Stock, the value of the consideration to be received
by Citizens shareholders resulting from the Exchange Ratio represented a fair
multiple of Citizens' per share book value and earnings. The Citizens Board also
considered that, under the proposed Exchange Ratio and based on the Citizens
Board's belief that Crestar would continue to pay dividends at its current rate,
the Holding Company Merger would result in a substantial increase in dividend
income to Citizens shareholders, although there can be no assurance that current
dividends are indicative of future dividends. See "Summary -- Comparative Per
Share Data." The Citizens Board also considered that the Holding Company Merger
would qualify as a tax-free reorganization under the Code. See " -- Certain
Federal Income Tax Consequences."
 
     (ii) The Non-Financial Terms of the Holding Company Merger. The Citizens
Board considered the social and economic effect on the employees, depositors and
customers of, and others dealing with, Citizens and on the communities in which
Citizens is located or operates. In analyzing the Non-Financial Terms of the
Holding Company Merger, the Citizens Board took into account Crestar's
undertaking to used its best efforts to provide employment to customer-
contact employees of Citizens and to freeze hiring within the Crestar
organization in the Greater Washington Region to provide employment
opportunities to other Citizens' personnel. The Board also considered
the fact that the acquisition would give Citizens' customers access
to a more comprehensive branch network of banking offices in Maryland,
Virginia and the District of Columbia, and would provide commercial
customers expertise in greater credit availability from a leading
commercial bank lender in Maryland. In considering the effect
on the communities in which Citizens operates, the Board was aware
"outstanding" Community Reinvestment Act ratings of the Crestar
affiliates.


     (iii) Certain Financial and Other Information Concerning Crestar. The
Citizens Board considered the business and financial condition of Crestar and
its favorable position among its peer group of national and regional financial
institutions in terms of profitability, capital adequacy and asset quality. The
Citizens Board also considered that the historical dividends per share and net
income per share of Crestar Common Stock to be received by Citizens stockholders
after giving effect to the Exchange Ratio, would represent a substantial
increase in the historical dividends per share and net income per share of
 
                                       17
 
<PAGE>
Citizens Common Stock, although there can be no assurance that pro forma amounts
are indicative of future dividends or income per share of Crestar. The Citizens
Board further considered the reputation and business practices of Crestar and
its management as they would affect the employees of Citizens.
 
     (iv) Other Possible Alternatives. Based in part on the advice of Keefe
Bruyette, the Citizens Board considered possible alternatives to the transaction
with Crestar, including remaining an independent institution.
 
     (v) Opinion of Financial Advisor. The Citizens Board considered the opinion
of Keefe Bruyette as to the fairness of the consideration to be received in the
Holding Company Merger to Citizens shareholders from a financial point of view.
See " -- Opinion of Financial Advisor."
 
     The Citizens Board believes that the Holding Company Merger and the
Agreement are advisable and are fair to, and in the best interests of, Citizens
and its shareholders. The Citizens Board unanimously recommends that Citizens
shareholders vote for the Agreement and the Holding Company Merger contemplated
thereby.
 
OPINIONS OF FINANCIAL ADVISORS
 
     CRESTAR. Crestar retained Morgan Stanley to act as Crestar's financial
advisor in connection with the Holding Company Merger and related matters based
upon its qualifications, expertise and reputation, as well as Morgan Stanley's
prior investment banking relationship and familiarity with Crestar. At the
September 12, 1996 meeting of the Crestar Board, Morgan Stanley delivered an
oral opinion to the Crestar Board that, as of such date and subject to certain
considerations set forth in the written opinion of Morgan Stanley dated
September 15, 1996, the Exchange Ratio pursuant to the Agreement is fair from a
financial point of view to Crestar. Morgan Stanley subsequently confirmed its
September 15, 1996, opinion by delivery to the Crestar Board of a written
opinion dated as of the date of this Joint Proxy Statement/Prospectus.
 
     The full text of Morgan Stanley's opinion, dated as of the date of this
Joint Proxy Statement/Prospectus, which sets forth, among other things,
assumptions made, procedures followed, matters considered, and limitations on
the review undertaken, is attached as Annex III to this Joint Proxy
Statement/Prospectus. Crestar stockholders are urged to, and should, read the
Morgan Stanley opinion carefully and in its entirety. Morgan Stanley's opinion
is directed to the Crestar Board and the fairness of the Exchange Ratio in the
Agreement from a financial point of view to Crestar, and it does not address any
other aspect of the Holding Company Merger nor does it constitute a
recommendation to any holder of Crestar Common Stock as to how to vote at the
Crestar Special Meeting.
 
     In connection with rendering its written opinion dated as of this Joint
Proxy Statement/Prospectus, Morgan Stanley, (i) analyzed certain publicly
available financial statements and other information of Citizens and Crestar,
respectively; (ii) analyzed certain internal financial statements and other
financial and operating data concerning Citizens and Crestar prepared by the
managements of Citizens and Crestar, respectively; (iii) analyzed certain
financial projections of Citizens and Crestar prepared by the managements of
Citizens and Crestar, respectively; (iv) discussed the past and current
operations and financial condition and the prospects of Citizens and Crestar
with senior executives of Citizens and Crestar, respectively; (v) analyzed the
pro forma impact of the Merger on Crestar's earnings per share, consolidated
capitalization and financial ratios; (vi) reviewed the reported prices and
trading activity for the Citizens Common Stock and the Crestar Common Stock;
(vii) compared the financial performance of Citizens and Crestar and the prices
and trading activity of the Citizens Common Stock and the Crestar Common Stock
with that of certain other comparable publicly-traded companies and their
securities; (viii) discussed with independent auditors of Citizens their review
of the financial and accounting affairs of Citizens and with the independent
auditors of Crestar their review of the financial and accounting affairs of
Crestar; (ix) discussed the results of regulatory examinations of Citizens and
Crestar with the senior management of the respective companies; (x) discussed
the strategic objectives of the Merger and the plan for the combined company
with senior executives of Citizens and Crestar; (xi) reviewed and discussed with
senior management of Citizens and Crestar certain estimates of the cost savings
and revenue enhancements projected by Citizens and Crestar for the combined
company and compared such amounts to those estimated in certain precedent
transactions; (xii) reviewed the financial terms, to the extent publicly
available, of certain comparable precedent transactions; (xiii) participated in
discussions and negotiations among representatives of Citizens and Crestar and
their financial and legal advisors; and (xiv) reviewed the Agreement and certain
related documents; and (xv) considered such other factors as were deemed
appropriate.
 
     In rendering its opinion, Morgan Stanley assumed and relied upon without
independent verification the accuracy and completeness of the information
reviewed by Morgan Stanley for the purposes of its opinion. With respect to the
financial projections, including the estimates of cost savings and revenue
enhancements expected to result from the Merger, Morgan
 
                                       18

Stanley assumed that they had been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the future financial
performance of Citizens and Crestar. Morgan Stanley has not made any independent
valuation or appraisal of the assets or liabilities of Citizens and Crestar, nor
has Morgan Stanley been furnished with any such appraisals, and Morgan Stanley
has not examined any individual loan credit files of Citizens and Crestar. In
addition, Morgan Stanley has assumed the Holding Company Merger will be
consummated in accordance with the terms set forth in the Agreement. Morgan
Stanley's opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to it, as of the date of
such opinion.
 
     The following is a brief summary of the financial analyses performed by
Morgan Stanley and reviewed with the Crestar Board on September 12, 1996 in
connection with rendering its opinion on such date.
 
     COMPARABLE COMPANY ANALYSIS. As part of its analysis, Morgan Stanley
compared certain financial information of Citizens with corresponding publicly
available information of (i) a group of four publicly traded bank holding
companies that Morgan Stanley considered comparable in certain respects with
Citizens (the "Peer Group"), and (ii) 35 regional bank holding companies (the
"Morgan Stanley Bank Index" and together with the Peer Group, the
"Comparables"). Historical financial information used in connection with the
ratios provided below with respect to the Comparables is as of June 30, 1996.
 
     Morgan Stanley analyzed the relative performance and value of Citizens by
comparing certain market trading statistics for Citizens with the Comparables.
Market information used in ratios provided below is as of September 11, 1996.
The market trading information used in the valuation analysis was market price
to book value (which was 1.4x in the case of Citizens; 1.6x in the case of the
average of the Peer Group; and 2.1 x in the case of the average of the Morgan
Stanley Bank Index) and market price to estimated earnings per share for 1996
(which was 11.8x in the case of Citizens; 12.6x in the case of the average of
the Peer Group; and 12.2x in the case of the average of the Morgan Stanley Bank
Index). Earnings per share estimates for Citizens were based on First Call
estimates as of September 11, 1996. Earnings per share estimates for the Morgan
Stanley Bank Index and the Peer Group were based on the most recent available
Institutional Brokers Estimate System ("I/B/E/S") estimates. I/B/E/S and First
Call are data services that monitor and publish compilations of earnings
estimates produced by selected research analysts regarding companies of interest
to institutional stockholders. The implied range of stand-alone values for
Citizens Common Stock derived from the analysis of the Comparables' market price
to book value and market price to 1996 estimated earnings per share ranged from
approximately $28 to $34.

     DIVIDEND DISCOUNT ANALYSIS. Morgan Stanley performed a dividend discount
analysis to determine a range of present values per share of Citizens Common
Stock assuming Citizens continued to operate as a stand-alone entity. This range
was determined by adding (i) the present value of the estimated future dividend
stream that Citizens could generate, and (ii) the present value of the "terminal
value" of Citizens Common Stock at the end of year 2001. To determine a
projected dividend stream, Morgan Stanley assumed a constant equity/assets ratio
of 7%. The earnings projections which formed the basis for the dividends were
adapted from First Call estimates for 1996 and 1997 as of September 11, 1996,
and earnings growth rates ranging from 6% to 10% for estimating earnings for
1998 through 2001. The "terminal value" of Citizens Common Stock at the end of
the period was determined by applying two price-to-earnings multiples (10.5x and
11.5x) to year 2001 projected earnings. The dividend stream and terminal values
were discounted to present values using discount rates of 11% and 13% which
Morgan Stanley viewed as the appropriate discount rate range for a company with
Citizens' risk characteristics. Based on the above assumptions, the stand-alone
value of Citizens Common Stock ranged from approximately $28 to $37 per share.
 
     IMPLIED ACQUISITION VALUE. As part of its analysis of the acquisition
valuation, Morgan Stanley assumed that the net present value of estimated cost
savings and revenue enhancements was added to the stand-alone value of Citizens
Common Stock calculated using First Call estimates as described above (see
"Dividend Discount Analysis" above). Based on cost savings ranging from $46 to
$58 million (40% to 50% of Citizens' non-interest expense base) and revenue
enhancements of $5-$10 million per year beginning in 1998 estimated by the
management of Crestar to result from the Holding Company Merger, discount rates
of 11% and 13%, a phase-in of cost savings over two years, a cost savings and
revenue enhancement growth rate of 2% after the phase-in period, merger and
reorganization charges equal to fully phased-in pre-tax cost savings incurred in
the first year following the Holding Company Merger and price-to-earnings
terminal multiples of 10.5x and 11.5x in the year 2001, Morgan Stanley estimated
the implied acquisition value of Citizens Common Stock to range from
approximately $46 to $57. Based on the closing market price on September 11,
1996 of $60.125 for Crestar Common Stock and the Common Exchange Ratio of 0.835,
the value to be received in the Merger per share of Citizens Common Stock would
be $50.20. The actual value received will depend on the value of Crestar Common
Stock at the Effective Time of the Holding Company Merger.
 
     PRECEDENT TRANSACTION ANALYSIS. Morgan Stanley performed an analysis of
nine precedent transactions ("Precedent Transactions") by selected holding
companies of commercial banks that Morgan Stanley deemed comparable to the
Merger
 
                                       19
 
<PAGE>
in order to calculate a valuation range for the Citizens Common Stock. Multiples
of book value and earnings implied by the consideration paid in Precedent
Transactions were applied to book value and 1997 estimated earnings per share of
Citizens to yield a range of values for Citizens Common Stock.
 
     Ranges of multiples of book value and of estimated earnings (based on
I/B/E/S estimates prior to announcement) per share ranging from 1.9x to 2.3x and
from 13.5x to 16.5x, respectively, derived from the comparable transactions were
applied to the book value and 1997 estimated earnings (based on First Call
estimates as of September 11, 1996 per share of Citizens to yield an implied
range of values for Citizens Common Stock ranging from approximately $39 to $53.
Based on the closing market price on September 11, 1996 of $60.125 for Crestar
Common Stock and the Common Exchange Ratio of 0.835, the value to be received in
the Merger per share of Citizens Common Stock would be $50.20. The actual value
received will depend on the value of Crestar Common Stock at the Effective Time
of the Holding Company Merger.
 
     PRO FORMA MERGER ANALYSIS. Morgan Stanley analyzed the financial impact of
the Holding Company Merger on the holders of Crestar Common Stock, using First
Call earnings estimates and Crestar's estimates for cost savings and revenue
enhancements expected to result from the Holding Company Merger. This analysis
showed that, after giving effect to the Holding Company Merger, before the
impact of one-time merger-related charges, current holders of Crestar Common
Stock would realize a decrease in fully diluted earnings per share in 1997 and
an increase in fully diluted earnings per share in 1998, in each case compared
to Crestar on a stand-alone basis. Morgan Stanley also analyzed the changes in
return on equity from Crestar on a stand-alone basis, noting that such return on
equity would increase following the Holding Company Merger. In addition, Morgan
Stanley calculated that the Exchange Ratio would result in an allocation between
the holders of Citizens Common Stock and Crestar Common Stock of pro forma fully
diluted ownership of the combined entity equal to 23% and 77%, respectively.
 
     In connection with its written opinion dated as of the date of this Joint
Proxy Statement/Prospectus, Morgan Stanley confirmed the appropriateness of its
reliance on the analyses used to render its September 15, 1996 opinion by
performing procedures to update certain of such analyses and by reviewing the
assumptions upon which such analyses were based and the factors considered in
connection therewith.
 
     No company or transaction used in the comparable company and comparable
transaction analyses is identical to Citizens or the Holding Company Merger.
Accordingly, the analysis of the results of the forgoing necessarily involves
complex considerations and judgments concerning financial and operating
characteristics of Citizens and other factors that could affect the public
trading value of the companies to which they are being compared. Mathematical
analysis (such as determining the average or median) is not in itself a
meaningful method of using comparable transaction data or comparable company
data.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, Morgan Stanley considered the results of all its
analysis as a whole and did not attribute any particular weight to any analysis
or factor considered by it. Morgan Stanley believes that selecting any portion
of its analyses, without considering all analyses, would create an incomplete
view of the process underlying its opinion. In addition, Morgan Stanley may have
deemed various assumptions more or less probable than other assumptions, so that
the ranges of valuations resulting from any particular analysis described above
should not be taken to be Morgan Stanley's view of the actual value of Citizens.
 
     In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Citizens or Crestar. The
analyses performed by Morgan Stanley are not necessarily indicative of actual
values, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as a part of Morgan Stanley's
analysis of the fairness from a financial point of view of the Exchange Ratio
pursuant to the Agreement to the holders of Crestar Common Stock and were
conducted in connection with the delivery of Morgan Stanley's opinion. The
analyses do not purport to be appraisals or to reflect the prices at which
Citizens might actually be sold.
 
     As described above, Morgan Stanley's opinion and the information provided
by Morgan Stanley to the Crestar Board were two of a number of factors taken
into consideration by the Crestar Board in making its determination to recommend
approval of the Agreement and the transactions contemplated thereby.
Consequently, the Morgan Stanley analyses described above should not be viewed
as determinative of the opinion of the entire Crestar Board or the view of the
management with respect to the value of Citizens. The Exchange Ratio pursuant to
the Agreement was determined through negotiations between Crestar and its
advisors and Citizens, and was approved by the entire Crestar Board.

     The Crestar Board retained Morgan Stanley based upon its experience and
expertise. Morgan Stanley is an internationally recognized investment banking
and advisory firm. As part of its investment banking business, Morgan Stanley is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuation for estate, corporate and other purposes. Morgan Stanley makes a
market in Crestar Common Stock. In the course of its business, Morgan Stanley
and its affiliates may actively trade the debt and equity securities of Citizens
and Crestar for their own account and for the accounts of customers and,
accordingly may at times hold a long or short position in such securities. In
the past two years , Morgan Stanley has been paid fees of $650,000 for services
rendered to Crestar, including acting as lead managing underwriter for Crestar's
issuance of subordinated notes and for financial advisory services.
 
     Pursuant to a letter dated August 22, 1996, Crestar has agreed to pay
Morgan Stanley: (i) an advisory fee estimated to be between $100,000 and
$150,000 which is payable if the Holding Company Merger is not consummated and
(ii) a transaction fee of $3.5 million which is payable upon the consummation of
the Holding Company Merger. Any advisory fee paid will be credited against the
transaction fee. In addition, Crestar has agreed, among other things, to
reimburse Morgan Stanley for all reasonable out-of-pocket expenses incurred in
connection with the services provided by Morgan Stanley, and to indemnify and
hold harmless Morgan Stanley and certain related parties from and against
certain liabilities and expenses, which may include certain liabilities under
the federal securities laws, in connection with its engagement.
 
     CITIZENS. Citizens retained Keefe Bruyette to render an opinion with
respect to the fairness from a financial point of view of the consideration to
be received by the shareholders of Citizens in the Holding Company Merger. Keefe
Bruyette was selected to act as Citizens' financial advisor based upon its
qualifications, expertise and reputation. Keefe Bruyette specializes in the
securities of banking enterprises and regularly engages in the valuation of
banking businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes.
 
     In the ordinary course of its business as a broker-dealer, Keefe Bruyette
may, from time to time, purchase securities from, and sell securities to,
Citizens and Crestar, and as a market maker in securities, Keefe Bruyette may
from time to time have a long or short position in, and buy or sell, equity
securities of Citizens and Crestar for its own account and for the accounts of
its customers. To the extent that Keefe Bruyette has any such position as of the
date of the fairness opinion attached as Annex IV hereto, it has been disclosed
to Citizens.
 
     On September 15, 1996, at the meeting at which the Citizens Board approved
and adopted the Agreement and the transactions contemplated thereby, Keefe
Bruyette rendered its oral opinion to the Citizens Board that, as of such date,
the Exchange Ratio was fair to the shareholders of Citizens from a financial
point of view. That opinion was updated as of the date of this Joint Proxy
Statement/Prospectus. In connection with its opinion dated the date of this
Joint Proxy Statement/Prospectus, Keefe Bruyette also confirmed the
appropriateness of its reliance on the analyses used to render its September 15,
1996 opinion by performing procedures to update certain of such analyses and by
reviewing the assumptions on which such analyses were based and the factors
considered in connection therewith. No limitations were imposed by the Citizens
Board upon Keefe Bruyette with respect to the investigations made or procedures
followed by Keefe Bruyette in rendering its opinions.
 
     Keefe Bruyette's opinion is addressed to the Board of Directors of Citizens
and does not constitute a recommendation to any of the shareholders of Citizens
as to how such shareholders should vote with respect to the Merger Agreement.
 
     The full text of the opinion of Keefe Bruyette, which sets forth a
description of the procedures followed, assumptions made, matters considered and
limits on the review undertaken, is attached to this Joint Proxy
Statement/Prospectus as Annex IV and is incorporated herein by reference.
shareholders are urged to read the opinion in its entirety.
 
     In rendering its opinion, Keefe Bruyette reviewed, analyzed and relied upon
the following material relating to the financial and operating condition of
Citizens and Crestar: (i) the Agreement; (ii) Annual Reports to Shareholders for
the three years ended December 31, 1995 for Citizens and Crestar; (iii) certain
interim reports to shareholders of Citizens and Crestar and Quarterly Reports on
Form 10-Q of Citizens and Crestar and certain other communications from Citizens
and Crestar to their respective shareholders; (iv) other financial information
concerning the businesses and operations of Citizens and Crestar furnished to
Keefe Bruyette by Citizens and Crestar for the purpose of Keefe Bruyette's
analysis, including certain internal financial analyses and forecasts for
Crestar prepared by senior management of Crestar; (v) certain publicly available
information concerning the trading of, and the trading market for, the Common
Stock of Citizens and Crestar; and (vi) certain publicly available information
with respect to banking companies and the nature and terms of certain other
transactions that Keefe Bruyette considered relevant to its inquiry.
Additionally, in connection with its written opinion attached as Annex IV
 
                                       21

to this Joint Proxy Statement/Prospectus, Keefe Bruyette reviewed a draft of
this Joint Proxy Statement/Prospectus in substantially the form hereof. Keefe
Bruyette also held discussions with senior management of Citizens and Crestar
concerning their past and current operations, financial condition and prospects,
as well as the results of regulatory examinations. Keefe Bruyette took into
account its assessment of general economic, market and financial conditions and
its experience in similar transactions, as well as its experience in securities
valuation and its knowledge of banks, bank holding companies and thrift
institutions generally. Keefe Bruyette's opinion was necessarily based upon
conditions as they existed and could be evaluated on the date thereof and the
information made available to Keefe Bruyette through the date thereof.
 
     In conducting its review and arriving at its opinion, Keefe Bruyette relied
upon and assumed the accuracy and completeness of all of the financial and other
information provided to it or publicly available, and Keefe Bruyette did not
attempt to verify such information independently. Keefe Bruyette relied upon the
management Crestar as to the reasonableness and achievability of the financial
and operating forecasts (the assumptions and bases therefor) provided to Keefe
Bruyette and assumed that such forecasts reflected the best available estimates
and judgments of Crestar management and that such forecasts will be realized in
the amounts and in the time periods estimated by Crestar management. Keefe
Bruyette also assumed, without independent verification, that the aggregate
allowances for loan losses for Citizens and Crestar are adequate to cover such
losses. Keefe Bruyette did not make or obtain any evaluations or appraisals of
the property of Citizens or Crestar, nor did Keefe Bruyette examine any
individual loan credit files. Keefe Bruyette was informed by Citizens, and
assumed for purposes of its opinion, that the Merger would be accounted for as a
pooling-of-interests under generally accepted accounting principles.
 
     The following is a summary of the material financial analyses employed by
Keefe Bruyette in connection with providing its oral opinion of September 15,
1996 and does not purport to be a complete description of all analyses employed
by Keefe Bruyette, although all material elements of the opinion are included in
the summary.
 
     ANALYSIS OF THE CRESTAR OFFER. Keefe Bruyette reviewed certain historical
financial information for Citizens and Crestar and calculated the imputed value
of the Crestar offer to holders of Citizens Common Stock. Keefe Bruyette
calculated the multiple which the Exchange Ratio represents, based on an assumed
per share purchase price of $51.25, when compared to June 30, 1996 stated book
value per share of $22.86, its stated tangible book value for the same period of
$22.26 per share, its trailing twelve months earnings per share of $2.49, its
1997 earnings estimate of $3.00 per share, its 1998 earnings estimate of $3.25
per share and its market price as of September 13, 1996 of $32.25. Based on
these assumptions, the price to stated book value multiple was 2.24 times, the
price to stated tangible book value was 2.30 times, the price to trailing twelve
month earnings per share was 20.61 times, the price to the 1997 earnings
estimate per share multiple was 17.08 times, the price to the 1998 earnings
estimate per share multiple was 15.77 times and the price to current market
price was 1.59 times.
 
     SELECTED PEER GROUP ANALYSIS. Keefe Bruyette compared the financial
performance and market performance of Crestar based on various financial
measures of earnings performance, operating efficiency, capital adequacy and
asset quality and various measures of market performance, including market/book
values, price to earnings and dividend yields to those of a group of comparable
companies. For purposes of such analysis, the financial information used by
Keefe Bruyette for Crestar and the comparable companies was as of and for the
quarter ended June 30, 1996 and the market price information was as of September
13, 1996. The companies in the peer group had total assets ranging from
approximately $17.9 billion to $23.6 billion, and included SouthTrust
Corporation, Summit Bancorp, First of America Bank Corp., Southern National
Corp., Huntington Bancshares, Inc., Fifth Third Bancorp, Firstar Corporation,
AmSouth Bancorporation, Mercantile Bancorporation and Regions Financial
Corporation.
 
     Keefe Bruyette's analysis showed the following concerning the financial
performance of Crestar: that the return on equity on an annualized basis was
15.36% compared to an average of 16.70% for the peer group; that return on
assets on an annualized basis was 1.28% compared to an average of 1.35% for the
group; that net interest margin on an annualized basis was 4.47% compared with
an average of 4.28%; that the efficiency ratio on an annualized basis was 58.25%
compared to an average of 55.68%; that the equity to assets ratio was 7.74%
compared to an average of 8.10%; that the tangible equity to assets ratio was
6.79% compared to an average of 7.10%; that the ratio of nonperforming assets to
total loans and other real estate loans was .78% compared to an average of .73%;
that the ratio of loan loss reserve to nonperforming loans was 319% compared to
an average of 279%.
 
     Keefe Bruyette's analysis further showed the following concerning the
market performance of Crestar: that the price to earnings multiple based on 1997
estimated earnings was 10.49 times compared to an average of 11.49 times; that
the price to book value multiple was 1.80 times compared to an average of 2.09
times; that the price to tangible book value was 2.08 times compared to an
average of 2.41 times and that the dividend yield was 3.39% compared to an
average of 3.19%.

     ANALYSIS OF SELECTED MERGER TRANSACTIONS. Keefe Bruyette reviewed certain
financial data related to two sets of recent comparable bank acquisitions. The
first set was comprised of bank acquisitions announced from January 1, 1994 with
the acquiree's assets between $2.0 and $10.0 billion and included the following
transactions (identified by acquirer/acquiree): National Australia Bank/Michigan
National Corp., US Bancorp/West One Bancorp, BB&T Financial Corp/Southern
National, Union Bank/BanCal Tri-State, Boatmen's Bancshares/Fourth Financial,
NationsBank Corp/Bank South Corp, UJB Financial/Summit Bancorp, Banc One
Corporation/Premier Bancorp, First Bank System/FirsTier Financial, Boatmen's
Bancshares/Worthen Banking Corp., National Westminster/Citizens First Bancorp,
Regions Financial/First National Bancorp, Union Planters Corp./Grenada Sunburst,
and First Fidelity Bancorp/Baltimore Bancorp.
 
     Keefe Bruyette calculated an average and median for the comparable group
(measured September 11, 1996) for the multiple of the targets' earnings
(trailing 12 months) of 16.2x and 13.9x respectively compared to a multiple of
20.6x associated with the Crestar proposal; an average and median premium to the
targets' stated book value of 197% compared to a multiple of 224% associated
with the Crestar proposal; an average and median premium to the targets'
tangible book value of 211% and 213% respectively compared to a multiple of 230%
associated with the Crestar proposal.
 
     The second set was composed of bank acquisitions announced from January 1,
1995 with the acquiree's assets between $2.0 and $20.0 billion and included the
following transactions (identified by acquirer/acquiree): Bank of
Boston/BayBanks, Regions Financial/First National Bancorp, CoreStates
Financial/Meridian Bancorp, UJB Financial/Summit Bancorporation, NationsBank
Corp/Bank South Corporation, National City Corporation/Integra Financial,
Boatmen's Bancshares/Fourth Financial, First Bank System/FirsTier Financial,
Banc One Corporation/Premier Bancorp, PNC Bank Corp/Midlantic Corp, Union
Bank/BanCal Tri-State, US Bancorp/West One Bancorp, National Australia
Bank/Michigan National Corp.
 
     Keefe Bruyette calculated an average and median for the group (measured
September 11, 1996) for the multiple of the targets' earnings (trailing 12
months) of 15.5x and 13.9x respectively compared to a multiple of 20.6x
associated with the Crestar proposal; an average and median premium to the
targets' stated book value of 197% and 198% respectively compared to a multiple
of 224% associated with the Crestar proposal; an average and median premium to
the targets' tangible book value of 213% and 215% respectively compared to a
multiple of 230% associated with the Crestar proposal.
 
     No company or transaction used as a comparison in the above analysis is
identical to Citizens, Crestar or the Merger. Accordingly, an analysis of the
results of the foregoing is not mathematical; rather, it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the public
trading value of the companies to which they are being compared.
 
     CONTRIBUTION ANALYSIS. Keefe Bruyette analyzed the relative contribution of
each of Citizens and Crestar to certain balance sheet, income statement and
asset quality items, including assets, deposits, shareholder's equity and
trailing twelve month earnings. The contribution analysis showed that under the
Crestar proposal, Citizens would contribute approximately 18% of the combined
assets, 19% of the combined deposits, 20% of the combined shareholder's equity
and 15% of the trailing twelve month earnings of the two companies (before cost
savings).
 
     VALUE OF THE EXCHANGE. Based on the Exchange Ratio, Keefe Bruyette
determined the value to Citizen shareholders as measured by Citizens' June 1996
book value per share, 1997 earnings per share estimate, 1997 dividend per share
estimate and market value per share which were for Citizens $22.86, $3.00, $1.20
and $33.25 respectively. Applying the Exchange Ratio to Crestar's June 1996 book
value of $33.46, creates an increase in book value to Citizens' shareholders of
14.7% or $3.35, an increase in 1997 earnings per share estimate of 60.2% or
$1.81, an increase in 1997 dividend per share estimate of 44.7% or $.54 and an
increase in the market value per share of 58.9% or $19.00.
 
     PRO FORMA EPS. Keefe Bruyette analyzed the pro forma earnings per share of
the combined company based on the Exchange Ratio of 0.835 shares of Crestar
Common Stock for each share of Citizens Common Stock. Based on the 1997 EPS
estimates of $3.00 and $5.85 for Citizens and Crestar respectively, the combined
company's pro forma EPS is estimated at $5.76 for 1997 including cost savings of
approximately $23.9 million (after tax) which represents 1.6% dilution to
Crestar's 1997 earnings. Based on the 1998 earnings estimates of $3.25 and $6.39
per share for Crestar and Citizens respectively, the combined company's pro
forma earnings per share is estimated at $6.43 for 1998 including cost saves of
approximately $34.3 million (after tax) which represents 0.6% accretion to
Crestar's 1998 earnings.
 
     DISCOUNTED CASH FLOW ANALYSIS. Keefe Bruyette compared the present value of
future cash flows that would accrue to a holder of a share of Citizens Common
Stock assuming Citizens were to remain independent to the present value of
future cash flows that would accrue to a holder of 0.835 shares of Crestar
Common Stock assuming the Merger were to occur. This analysis assumed 10% and 9%
annual earnings per share growth for Citizens and Crestar respectively, 6% and
8% annual
 
                                       23
 
<PAGE>
dividend growth for Citizens and Crestar respectively, a trading multiple of
10.5 times earnings for the year 2001 for Citizens, as well as a discount rate
of 14%. Based on such assumptions, Keefe Bruyette's analysis indicated that the
present value of a share of Citizens Common Stock, on a stand alone basis would
be $28.37 compared with a present value of $43.74 for 0.835 shares of Crestar
Common Stock. Keefe Bruyette also presented a table showing the foregoing
analysis with a range of discount rates from 10% to 15% and a range of price to
earnings multiples of 10 times to 15 times, resulting in a range of present
values for a share of Citizens Common Stock of $26.15 to $45.81. Keefe Bruyette
repeated the foregoing analysis under an alternative scenario in which each
entity is acquired in 2001 for a price equal to 15 times 2001 earnings per
share. Such analysis indicated a present value for a share of Citizens Common
Stock of $38.64, compared with a present value of .835 shares of Crestar Common
Stock of $60.69. Keefe Bruyette stated that the discounted cash flow analysis is
a widely-used valuation methodology but noted that it relies on numerous
assumptions, including asset and earnings growth rates, dividend payout rates,
terminal values and discount rates. The analysis did not purport to be
indicative of the actual values or expected values of Citizens Common Stock or
Crestar Common Stock.
 
     MARKET REACTION. Keefe Bruyette analyzed the market's reaction to four
comparable bank acquisitions as measured by the change in the acquirors' price
subsequent to the announcement of the acquisition. The four transactions were
(as identified by acquiror/acquiree): NationsBank Corporation/Boatmen's
Bancshares, Bank of Boston/BayBanks, Inc., CoreStates Financial/Meridian Bancorp
and UJB Financial Corp./Summit Bancorporation. The change in acquiror's price
one day after announcement was -9.1%, -2.7%, -0.8% and -9.2% respectively. The
change in acquiror's price ten days after announcement was NA, -4.0%, .3% and
- -10.6%. The change in acquiror's price as of September 10, 1996 was -9.2%,
13.4%, 8.4% and 6.5% respectively. For comparison purposes, Keefe Bruyette
examined the change in Keefe Bank Index for the same periods which resulted in a
change in the Keefe Bank Index of 2.6%, 13.5%, 18.2% and 25.1% respectively.
 

     The summary contained herein provides a description of the material
analyses prepared by Keefe Bruyette in connection with the rendering of its
opinion. The preparation of a fairness opinion is not necessarily susceptible to
partial analysis or summary description. Keefe Bruyette believes that its
analyses and the summary set forth above must be considered as a whole and that
selecting portions of its analyses without considering all analyses, or
selecting part of the above summary, without considering all factors and
analyses, would create an incomplete view of the processes underlying the
analyses set forth in Keefe Bruyette's presentations and opinion. The ranges of
valuations resulting from any particular analysis described above should not be
taken to be Keefe Bruyette's view of the actual value of Citizens and Crestar.
Although all material valuation methodologies employed by Keefe, Bruyette have
been disclosed, the fact that any specific analysis has been referred to in the
summary above is not meant to indicate that such analysis was given greater
weight than any other analyses.


 
     In performing its analyses, Keefe Bruyette made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Citizens and Crestar. The
analyses performed by Keefe Bruyette are not necessarily indicative of actual
values or actual future results which may be significantly more or less
favorable than suggested by such analyses. Such analyses were prepared solely as
part of Keefe Bruyette's analysis of the fairness, from a financial point of
view, of the Exchange Ratio and were provided to the Citizens Board in
connection with the delivery of Keefe Bruyette's opinion. The analyses do not
purport to be appraisals or to reflect the prices at which a company actually
might be sold or the prices at which any securities may trade at the present
time or at any time in the future. In addition, as described above, Keefe
Bruyette's opinion, along with its presentation to the Citizens Board, was just
one of many factors taken into consideration by the Citizens Board in
unanimously approving the Agreement.
 
     Pursuant to the Engagement Letter dated September 9, 1996, Citizens agreed
to pay Keefe Bruyette a cash fee of $100,000 promptly upon the signing of a
merger agreement between Citizens and Crestar, $200,000 upon the mailing of the
Proxy Statement/Prospectus relating to the proposed merger and $390,000 upon
consummation of the proposed merger. In addition, Citizens agreed to reimburse
Keefe, Bruyette for all reasonable out-of-pocket expenses, not to exceed
$10,000, incurred in connection with the services provided by Keefe, Bruyette,
and to indemnify and hold harmless Keefe, Bruyette and certain related parties
from and against certain liabilities and expenses, which may include certain
liabilities under the federal securities laws, in connection with its
engagement.
 
EFFECTIVE TIME OF THE HOLDING COMPANY MERGER
 
     The Holding Company Merger is expected to be consummated by December 31,
1996. The Holding Company Merger will be effective on the date (the "Effective
Date") and the time (the "Effective Time") specified in the Articles of Merger
that are to be filed with the SDAT (Maryland) and the SCC (Virginia) as soon as
practicable following satisfaction of all the conditions to the consummation of
the Holding Company Merger set forth in the Agreement. Either Citizens or
Crestar,
 
                                       24
 
<PAGE>
acting unilaterally, may terminate the Agreement if the Holding Company Merger
has not been consummated by June 30, 1997.
 
     Until the Effective Time of the Holding Company Merger occurs, Citizens
shareholders will retain their rights as shareholders to vote on matters
submitted to them by the Citizens Board.
 
DETERMINATION OF EXCHANGE RATIO AND EXCHANGE FOR CRESTAR COMMON STOCK
 
     Crestar and Citizens valued Citizens Common Stock at $48.50 per share and
valued Crestar Common Stock at $58 per share for the purpose of determining the
Exchange Ratio. Using these two values, an Exchange Ratio of 0.835 shares of
Crestar Common Stock for each share of Citizens Common Stock was negotiated. The
Exchange Ratio, as finally negotiated, was directly related to stock market
conditions generally and, more specifically, to the market value of Crestar
Common Stock. Crestar and Citizens recognized that a fixed Exchange Ratio would
result in a fluctuating value for Citizens Common Stock which reflects the
market price of Crestar Common Stock.
 
     Each share of Citizens Common Stock (other than shares held directly by
Crestar, which will be canceled without payment therefor) will be converted into
0.835 shares of Crestar Common Stock, and an identical number of Rights.
Citizens has the right to terminate the Agreement during the five-day period
prior to the fifth day prior to the Closing Date if the Average Closing Price of
Crestar Common Stock is $48.00 or less during the 10-trading day period ending
on the 10th day prior to the Closing Date. If Citizens takes this action,
Crestar has the option during the five-day period following notice of
termination to postpone the Closing Date for 15 trading days, during the first
10 trading days on which an Adjusted Average Closing Price of Crestar Common
Stock will be determined. If the Adjusted Average Closing Price is more than
$48.00, no termination shall be deemed to have occurred and the Agreement will
remain in effect. If the Adjusted Average Closing Price is $48.00 or less,
Crestar has the option of increasing the consideration to be received by holders
of Citizens Common Stock hereunder by adjusting the Exchange Ratio to equal a
number equal to the quotient obtained by dividing $40.08 by the Adjusted Average
Closing Price. If Crestar increases the Exchange Ratio, no termination is deemed
to have occurred and the Agreement remains in force in accordance with its terms
(except as the Exchange Ratio shall have been so modified). In no event is the
modified Exchange Ratio to be less than 0.835 shares of Crestar Common Stock for
each share of Citizens Common Stock. The terms "Average Closing Price" and
"Adjusted Average Closing Price" mean the average of the closing sales price of
Crestar Common Stock as reported on the consolidated tape of the NYSE for each
of the 10 trading days in the relevant trading period.
 

     At September 30, 1996, there were 15,132,599 shares of Citizens Common
Stock outstanding. In addition, options to purchase an additional 674,250 shares
of Citizens Common Stock were outstanding at September 30, 1996. Based on the
number of shares of Citizens Common Stock outstanding and the number of options
to purchase Citizens Common Stock outstanding as of September 30, 1996, and an
Exchange Ratio of 0.835, Crestar would issue 12,635,720 shares of Crestar Common
Stock in exchange for Citizens Common Stock, and convert the outstanding options
to purchase Citizens Common Stock into 562,999 outstanding options to purchase
Crestar Common Stock. The aggregate number of shares of Crestar Common Stock to
be issued in connection with the Holding Company Merger, and the number of
options to purchase Citizens Common Stock that will be converted into options to
purchase Crestar Common Stock, will vary to the extent that any outstanding
options to purchase Citizens Common Stock are exercised prior to the Effective
Time of the Holding Company Merger. See " -- Effect on Citizens Employee Benefit
Plans" below.

 
     Following the Effective Time of the Holding Company Merger, former holders
of shares of Citizens Common Stock will be mailed a Letter of Transmittal which
will set forth the procedures that should be followed for exchange of Citizens
Common Stock for Crestar Common Stock.
 
     Shareholders of Citizens who receive Crestar Common Stock will be entitled
to receive certificates representing the number of whole shares of Crestar
Common Stock for which such shares have been submitted for exchange and cash in
lieu of any fractional share interest on the basis of the Exchange Ratio.

     Citizens and Citizens Bank have further agreed that neither Citizens,
Citizens Bank nor any of their executive officers, directors, representatives,
agents or affiliates shall, directly or indirectly, solicit or initiate
discussions or negotiations with any person other than Crestar concerning any
merger, sale of substantial assets, tender offer, sale of shares of stock or
similar transaction involving Citizens or Citizens Bank or disclose, directly or
indirectly, any information not customarily disclosed to the public concerning
Citizens or Citizens Bank, afford to any person other than Crestar access to the

any person who may be preparing to make or who has made such an offer, or enter
into any agreement with any third party providing for a business combination
transaction, equity investment or sale of a significant amount of assets, except
in a situation in which a majority of the full Citizens Board has determined in
good faith, upon advice of counsel, that such Board has a fiduciary duty to
consider and respond to a bona fide proposal by a third party (which proposal
was not directly or indirectly solicited by Citizens or Citizens Bank or any of
their officers,
 
                                       26
 
<PAGE>
directors, representatives, agents or affiliates) and provides written notice of
its intention to consider such proposal and the material terms thereof to
Crestar at least five days before responding to the proposal. Citizens and
Citizens Bank will promptly communicate to Crestar the terms of any proposal
which it may receive in respect to any of the foregoing transactions.

within the meaning of Section 201.01 of the SEC's Codification of Financial

Stock shall not be transferable until such time as financial results covering at
least 30 days of combined operations of Crestar and Citizens have been published
within the meaning of Section 201.01 of the SEC's Codification of Financial
Reporting Policies, regardless of whether each such affiliate has provided the
written letter agreement referred to in Section 5.1(g) of the Agreement (and

STOCK OPTION AGREEMENT
 
     Crestar and Citizens have entered into a Stock Option Agreement, dated as
of September 15, 1996 (the "Option Agreement"), pursuant to which Citizens
issued to Crestar an option (the "Option") to purchase up to 3,012,000 shares of
Citizens Common Stock at a purchase price of $40.00 per share.
 

     Crestar may exercise the Option upon the occurrence of certain events (each
a "Purchase Event"). The Option Agreement provides that a Purchase Event shall
mean the occurrence of any of the following events after the date of execution
of the Option Agreement: (i) Citizens or any banking subsidiary of Citizens (a
"Bank"), without having received Crestar's prior written consent, shall have
entered into an agreement with any person to: (x) merge, consolidate or enter
into any similar transaction, except as contemplated in the Agreement; (y)
purchase, lease or otherwise acquire all or substantially all of the assets of
Citizens or a Bank; or (z) purchase or otherwise acquire (including by way of
merger, consolidation, share exchange or any similar transaction) securities
representing 10% or more of the voting power of Citizens or a Bank; (ii) any
person (other than Citizens or a Bank in a fiduciary capacity, or Crestar or
Crestar Bank in a fiduciary capacity) shall have acquired beneficial ownership
or the right to acquire beneficial ownership of 15% or more of the outstanding
shares of Citizens Common Stock after the date of the Option Agreement; (iii)
any person shall have made a bona fide proposal to Citizens by public
announcement or written communication that is or becomes the subject of public
disclosure to acquire Citizens or a Bank by merger, consolidation, purchase of
all or substantially all of its assets or any other similar transaction, and
following such bona fide proposal the shareholders of Citizens vote not to adopt
the Agreement; or (iv) Citizens shall have willfully breached certain specified
covenants contained in the Agreement following a bona fide proposal to Citizens
or a Bank to acquire Citizens or a Bank by merger, consolidation, purchase of
all or substantially all of its assets or any other similar transaction, which
breach would entitle Crestar to terminate the Agreement (without regard to the
cure periods provided for therein) and such breach shall not have been cured
prior to the date on which Crestar shall notify Citizens of its intent to
exercise the Option.

 
     The Option may be exercised in whole or in part, at any time or from time
to time if a Purchase Event shall have occurred and be continuing and before the
Option Agreement is terminated, unless Crestar shall have breached in any
material respect any material covenant or representation contained in the
Agreement and such breach has not been cured. The Option Agreement provides that
to the extent that it shall have not been exercised, the Option shall terminate
(i) on the Effective Date of the Holding Company Merger; (ii) upon the
termination of the Agreement in accordance with the provisions thereof (other
than a termination resulting from a willful breach by Citizens of certain
specified covenants contained therein or, following the occurrence of a Purchase
Event, failure of Citizens shareholders to approve the Holding Company Merger by
the vote required under applicable law or under Citizens' Charter); or (iii) 12
months after termination of the Agreement due to a willful breach by Citizens of
certain specified covenants contained therein or, following the occurrence of a
Purchase Event, failure of Citizens shareholders to approve the Holding Company
Merger by the vote required under applicable law or under Citizens' Charter.
 
     Because the Option permits Crestar to purchase a significant number of
shares of Citizens Common Stock at a purchase price below the inferred value of
Citizens Common Stock reflected in the Exchange Ratio, any potential acquiror
triggering a Purchase Event would be required to absorb the difference between
the price Crestar would pay for shares of Citizens Common Stock upon exercise of
the Option ($40 per share), and the price the potential acquiror would be
required to offer to better the inferred value of Citizens Common Stock. This
could have the effect of deterring potential acquirors from topping the Crestar
offer.
 
WAIVER AND AMENDMENT; TERMINATION
 
     WAIVER AND AMENDMENT. Prior to the Effective Time of the Holding Company
Merger, any term or provision of the Agreement may be waived in writing at any
time by the party which is, or whose shareholders are, entitled to the benefits
thereof and the Agreement may be amended or supplemented by written instructions
duly executed by all parties hereto at any time, whether before or after the
Crestar Special Meeting or the Citizens Special Meeting, excepting statutory
requirements and requisite approvals of shareholders and regulatory authorities,
provided that any such amendment or waiver executed after shareholders of
Crestar or Citizens have approved the Agreement and the Holding Company Plan of
Merger shall not modify either the amount or form of the consideration to be
received by such Citizens shareholders for their shares of Citizens Common Stock
or otherwise materially adversely affect such shareholders without their
approval.

     TERMINATION. The Agreement shall be terminated, and the Transaction
abandoned, if the shareholders of Crestar or Citizens shall not have given the
approval of the Holding Company Merger. Notwithstanding such approval by such
shareholders, the Agreement may be terminated at any time prior to the Effective
Time of the Holding Company Merger, by:
 
                                       28
 
<PAGE>
(i) the mutual consent of Crestar and Citizens, as expressed by their respective
Boards of Directors; (ii) either Crestar on the one hand or Citizens on the
other hand, as expressed by their respective Boards of Directors, if the Holding
Company Merger has not occurred by June 30, 1997, provided that the failure of
the Holding Company Merger to so occur shall not be due to a willful breach of
any representation, warranty, covenant or agreement by the party seeking to
terminate the Agreement; (iii) Crestar in writing authorized by its Board of
Directors if Citizens or Citizens Bank has, or by Citizens in writing authorized
by its Board of Directors, if Crestar or Crestar Bank has, in any material
respect, breached (A) any covenant or agreement contained therein, or (B) any
representation or warranty contained in the Agreement, in any case if such
breach has not been cured by the earlier of 30 days after the date on which
written notice of such breach is given to the party committing such breach or
the Closing Date (as defined in the Agreement); provided that it is understood
and agreed that either party may terminate the Agreement on the basis of any
such material breach of any representation or warranty which is not cured within
30 days of written notice thereof contained in the Agreement, notwithstanding
any qualification therein relating to the knowledge of the other party; (iv)
either Crestar on the one hand or Citizens on the other hand, as expressed by
their respective Boards of Directors, in the event that any of the conditions
precedent to the obligations of such parties to consummate the Holding Company
Merger have not been satisfied or fulfilled or waived by the party entitled to
so waive on or before the Closing Date, provided that no party shall be entitled
to terminate the Agreement pursuant to this subparagraph (d) if the condition
precedent or conditions precedent which provide the basis for termination can
reasonably be and are satisfied within a reasonable period of time, in which
case, the Closing Date shall be appropriately postponed; (v) Citizens, if the
Citizens Board shall have determined in its sole discretion, exercised in good
faith, that the Holding Company Merger has become inadvisable or impracticable
by reason of (A) the institution of any litigation, proceeding or investigation
(including under federal antitrust laws) to restrain or prohibit the
consummation of the Transaction or to obtain other relief in connection with the
Agreement, or (B) commencement of a competing offer for Citizens Common Stock
which is significantly better than Crestar's offer, and which Crestar has
certified to Citizens, in writing, it is unwilling to meet; (vi) Crestar, if the
Crestar Board shall have determined in its sole discretion, exercised in good
faith, that the Holding Company Merger, has become inadvisable or impracticable
by reason of (A) the institution of any litigation, proceeding or investigation
(including under federal antitrust laws) to restrain or prohibit the
consummation of the Transaction or to obtain other relief in connection with the
Agreement or (B) public commencement of a competing offer for Citizens Common
Stock which is significantly better than Crestar's offer, and which Crestar
certifies to Citizens, in writing, it is unwilling to meet; (vii) Crestar or
Citizens, if the Federal Reserve Board, the Maryland Department, or the SCC deny
approval of the Transaction and the time period for all appeals or requests for
reconsideration has run; and (viii) Citizens, by action of its Board of
Directors, at any time during the five-day period prior to the fifth day prior
to the Closing Date, if the Average Closing Price as defined below of Crestar
Common Stock shall be $48.00 or less, provided, however, that during the
five-day period following the provision by Citizens of written notice of
termination to Crestar pursuant to the Agreement Crestar shall have the option
of postponing the Closing Date for 15 trading days, during the first 10 trading
days of which a new Average Closing Price of Crestar Common Stock shall be
determined based on the closing sales price of Crestar Common Stock as reported
on the consolidated tape on the NYSE for each of such 10 trading days (the
"Adjusted Average Closing Price"). If the Adjusted Average Closing Price is more
than $48.00, no termination shall be deemed to have occurred, and the Agreement
shall remain in full force and effect in accordance with its terms. If the
Adjusted Average Closing Price is $48.00 or less, Crestar shall have the option
of increasing the consideration to be received by holders of Citizens Common
Stock hereunder by adjusting the Exchange Ratio to equal a number equal to the
quotient obtained by dividing $40.08 by the Adjusted Average Closing Price, in
which case Crestar shall give prompt written notice to Citizens of such election
and the revised Exchange Ratio and no termination shall be deemed to have
occurred, and the Agreement shall remain in full force and effect in accordance
with its terms (except as the Exchange Ratio shall have been so modified and any
references herein to "Exchange Ratio" shall thereafter be deemed to refer to the
Exchange Ratio as adjusted pursuant to the Agreement). In no event shall the
modified Exchange Ratio be less than 0.835 shares of Crestar Common Stock for
each share of Citizens Common Stock. The "Average Closing Price" shall be the
average of the closing sales price of Crestar Common Stock as reported on the
consolidated tape on the NYSE for each of the 10 trading days ending on the 10th
day prior to the Closing Date established pursuant to the Agreement.
 
     In the event of the termination and abandonment of the Agreement and the
Holding Company Merger pursuant to the above, the Agreement, other than the
provisions of relating to confidentiality of information obtained by the parties
and to the payment of expenses relating to the Holding Company Merger, shall
become void and have no effect, without any liability on the part of any party
or its directors, officers or shareholders, provided that nothing contained in
the Agreement shall relieve any party from liability for any willful breach of
the Agreement.

ACCOUNTING TREATMENT
 
     Consummation of the Holding Company Merger is conditioned upon the receipt
by Crestar of a letter from KPMG Peat Marwick LLP to the effect that the Holding
Company Merger can be accounted for as a pooling-of-interests. See
" -- Conditions to Consummation of the Holding Company Merger." Under this
accounting treatment, as of the Effective Time of the Holding Company Merger,
the assets and liabilities of Citizens would be added to those of Crestar at
their recorded book values and the shareholders' equity accounts of Crestar and
Citizens would be combined on Crestar's consolidated balance sheet. On the
pooling-of-interests accounting basis, income and other financial statements of
Crestar issued after consummation of the Holding Company Merger would be
restated retroactively to reflect the consolidated combined financial position
and results of operations of Crestar and Citizens as if the Holding Company
Merger had taken place prior to the periods covered by such financial
statements.
 
OPERATIONS AFTER THE HOLDING COMPANY MERGER
 
     After the consummation of the Holding Company Merger, Crestar will continue
generally to conduct the business presently conducted by Citizens.
 
INTERESTS AND CONFLICTS OF INTEREST OF CERTAIN PERSONS IN THE HOLDING COMPANY
MERGER
 
     Certain members of Citizens' management may be deemed to have interests and
conflicts of interest in the Holding Company Merger in addition to their
interests as shareholders of Citizens generally. In each case, the Citizens
Board was aware of their potential interests and conflicts of interest, and
considered them, among other matters, in approving the Agreement and the
transactions contemplated thereby.
 
     EMPLOYMENT AGREEMENTS. Crestar will honor the terms of the employment and
severance agreements with Jeffrey R. Springer, Richard C. Bandiere, Raymond L.
Gazelle, Jr. and Gary N. Geisel.
 
     An employment agreement is currently in effect with Jeffrey R. Springer,
President and Chief Operating Officer of Citizens and Citizens Bank. Mr.
Springer is entitled to receive a minimum annual salary of $472,500, subject to
increases at the discretion of the board of directors, and annual cash bonuses.
During and following termination of employment, Mr. Springer is entitled to
receive health, disability and life insurance benefits. Mr. Springer
participates in retirement and pension plans and will receive guaranteed monthly
supplemental retirement benefit payments of approximately $21,000, assuming
retirement at age 55.
 
     The agreement may be terminated by Mr. Springer or by Citizens for any
reason upon written notice to the other. If the agreement is terminated by Mr.
Springer for other than "good reason" or by Citizens for "strict cause" or due
to disability, Mr. Springer will not be entitled to receive any further
compensation and benefits other than certain retirement benefits and, in the
case of disability, life insurance coverage.
 
     If the agreement is terminated by Mr. Springer for "good reason" or by
Citizens for any reason other than "strict cause," death or disability, Mr.
Springer shall be entitled to continuation of salary payments, insurance
benefits and certain retirement benefits for two years and to supplemental
retirement benefits. "Good reason" generally is defined as the assignment to Mr.
Springer without his consent, of duties materially inconsistent with his
responsibilities and status with Citizens Bank, the appointment of a higher
ranking full-time employee, the removal or failure to reelect Mr. Springer to
his current positions, or failure to pay him the compensation and benefits
provided in the agreement.
 
     In the event the agreement is terminated by either party in anticipation of
or following a "change in control," including Mr. Springer's election to retire
for "good reason" following a change in control, then, Mr. Springer is entitled
to a lump sum cash payment equal to 2.99 times his average annual salary and
bonuses included in gross income for the preceding five years. A "change in
control" generally refers to the acquisition by any person of beneficial
ownership of 25% or more of the combined voting power of the then outstanding
securities of Citizens or the sale of all or substantially all of the capital
stock or assets of Citizens Bank. The aggregate lump sum payment to be made to
Mr. Springer, assuming termination of employment and following a change in
control as described above at December 31, 1996, is $1,483,040.
 
     Citizens Bank has also entered into individual agreements with Messrs.
Bandiere, Gazelle, and Geisel providing for annual salaries, subject to annual
review adjustments, eligibility for annual cash bonuses based upon Citizens'
earnings and the executive's achievement of performance standards, annual
vacation and eligibility for stock options and for other benefits provided to
other employees of Citizens Bank. In the event an executive is terminated for
reasons other than death, disability or good cause, the agreements provide for
the continuation of salary payments and certain benefits for twelve months or
until employment by a financial services company in the Baltimore/Washington
area.
 
                                       30
 
<PAGE>
     In the event an executive's employment is terminated within two years of a
change in control and for reasons other than death, disability, or good cause,
or by the executive for "good reason," each of the agreements provides for the
continuation of salary payments and certain benefits for 30 months. Under this
provision and based on 1996 salaries, Messrs. Bandiere, Gazelle and Geisel would
be entitled to receive aggregate cash severance payments over 30 months of
$680,000, $595,000, and $672,500, respectively.
 
     INDEMNIFICATION; LIABILITY INSURANCE. Crestar has agreed to provide
indemnification to the directors, employees and officers of Citizens and
Citizens Bank and the subsidiaries thereof for events occurring prior to or
subsequent to the Effective Time of the Holding Company Merger as if they had
been directors, employees or officers of Crestar, to the extent permitted under
the Virginia State Corporation Act and the Articles of Incorporation and Bylaws
of Crestar. Crestar will provide directors' and officers' liability insurance
coverage to Citizens and Citizens Bank directors and officers, whether or not
they become part of the Crestar organization after the Effective Time of the
Holding Company Merger, to the same extent it is provided to Crestar's officers
and directors.
 
     ADVISORY BOARDS OF DIRECTORS. Crestar Bank will offer five to eight members
of the Citizens Board a position on Crestar Bank's GWR or Maryland advisory
boards. Members who agree to serve on an advisory board will be paid on the
usual terms and conditions that Crestar Bank pays other members of its GWR or
Maryland advisory boards, currently up to $5,000 per year depending on the
number of meetings attended.
 

     CRESTAR BOARD OF DIRECTORS. Crestar will increase the number of members of
Crestar's and Crestar Bank's Board of Directors by two and appoint Alfred H.
Smith, Jr. and Jeffrey R. Springer to fill the resulting vacancies. As directors
of Crestar, Messrs. Smith and Springer will be paid an annual retainer
(currently $18,000) and $1,000 per meeting attended, and an additional $500 for
a second meeting on the same day. Each also will participate in the Crestar
Directors' Equity Program, which annually awards Crestar Common Stock with a
value of $8,000 to directors as part of their compensation.

 
STOCK OPTIONS
 
     Holders of outstanding Citizens Options shall (a) exercise the Citizens
Options for Citizens Common Stock prior to the Closing Date (if such options are
by their terms then exercisable) and convert such Common Stock held as of the
Effective Time of the Holding Company Merger into Crestar Common Stock or (b)
have the Citizens Options converted into options to purchase Crestar Common
Stock.
 
EFFECT ON CITIZENS EMPLOYEE BENEFITS PLANS
 
     All employees of Citizens or Citizens Bank (including subsidiaries)
immediately prior to the Effective Time of the Holding Company Merger who are
employed by Crestar, Crestar Bank or another Crestar subsidiary immediately
following the Effective Time of the Holding Company Merger ("Transferred
Employees") will be covered by Crestar's employee benefit plans as to which they
are eligible based on their length of service, compensation, location, job
classification, and position, including, where applicable, any incentive
compensation plan. Notwithstanding the foregoing, Crestar may determine to
continue any of the Citizens or Citizens Bank benefit plans for Transferred
Employees in lieu of offering participation in Crestar's benefit plans providing
similar benefits (e.g., medical and hospitalization benefits), to terminate any
of the Citizens or Citizens Bank benefit plans, or to merge any such benefit
plans with Crestar's benefit plans. Except as specifically provided in the
Agreement and as otherwise prohibited by law, Transferred Employees' service
with Citizens or Citizens Bank which is recognized by the applicable benefit
plan of Citizens or Citizens Bank at the Effective Time of the Holding Company
Merger shall be recognized as service with Crestar for purposes of eligibility
to participate and vesting, if applicable (but not for purposes of benefit
accrual) under the corresponding Crestar benefit plan, if any, subject to
applicable break-in-service rules.
 
     Crestar agrees that any pre-existing condition, limitation or exclusion in
its health plans shall not apply to Transferred Employees or their covered
dependents who are covered under a medical or hospitalization indemnity plan
maintained by Citizens or Citizens Bank on the date of the Holding Company
Merger and who then change that coverage to Crestar's medical or hospitalization
indemnity health plan at the time such Transferred Employees are first given the
option to enroll in Crestar's health plans.
 
     Crestar agrees that immediately following the Holding Company Merger, all
participants who then have accounts in the 401(k) plan maintained by Citizens or
Citizens Bank (the "401(k) Plan") shall be fully vested in their account
balances. Crestar, at its election, may continue the 401(k) Plan for the benefit
of Transferred Employees (as such plan may be amended as of the Effective Time
of the Holding Company Merger to provide current contributions and eligibility
provisions identical
 
                                       31
 
<PAGE>
to those under the Crestar Employees' Thrift and Profit Sharing Plan (the
"Thrift Plan")), may merge the 401(k) Plan into the Thrift Plan or any other
defined contribution plan maintained by Crestar, or may cease additional benefit
accruals under and contributions to the 401(k) Plan and continue to hold the
assets of such Plan until they are distributable in accordance with its terms.
In the event of a merger of the 401(k) Plan into the Thrift Plan or a cessation
of accruals and contributions under the 401(k) Plan, the Thrift Plan will
recognize for purposes of eligibility to participate, early retirement, and
eligibility for vesting, all Transferred Employees' service which is recognized
under the 401(k) Plan, subject to applicable break-in-service rules.
 
     The Retirement Plan for Employees of Crestar Financial Corporation and
Affiliated Corporations ("Crestar's Retirement Plan") will recognize for
purposes of eligibility to participate, vesting and eligibility for early
retirement, but not for benefit accrual purposes, all Transferred Employees'
service which is recognized under the qualified employees' defined benefit
pension plan of Citizens (the "Citizens Pension Plan"), subject to applicable
break-in-service rules. Crestar, at its option, may continue the Citizens
Pension Plan as a frozen plan or may terminate the Citizens Pension Plan and pay
out or annuitize benefits, or may merge the Citizens Pension Plan into Crestar's
Retirement Plan. If the Citizens Pension Plan is terminated or if benefit
accruals are suspended, or if the Citizens Pension Plan is merged into Crestar's
Retirement Plan, each Transferred Employee who becomes a participant in
Crestar's Retirement Plan will begin to accrue benefits under Crestar's
Retirement Plan on and after the date of such termination, suspension or merger
in accordance with the terms of Crestar's Retirement Plan.
 
     Citizens and Citizens Bank have agreed to cooperate with Crestar in
implementing any decision made by Crestar under the Agreement with respect to
employee benefit plans and to provide to Crestar on or before the Effective Time
of the Holding Company Merger a schedule of service credit for prospective
Transferred Employees.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     Crestar has received the opinion of Hunton & Williams and Citizens has
received the opinion of Semmes, Bowen & Semmes that for federal income tax
purposes: (i) the Holding Company Merger and the Citizens/Crestar Merger
together will constitute a reorganization within the meaning of Section 368(a)
of the Code; and (ii) neither Citizens, Acquisition nor Crestar will recognize
any taxable gain or loss upon consummation of the Holding Company Merger or the
Citizens/Crestar Merger. In addition, Citizens has received the opinion of
Semmes, Bowen & Semmes that the Holding Company Merger together with the
Citizens/Crestar Merger will result in the federal income tax consequences
summarized below for Citizens shareholders who receive Crestar Common Stock in
exchange for Citizens Common Stock pursuant to the Holding Company Merger. Such
opinions have been filed as exhibits to the Registration Statement. Receipt of
substantially the same opinions as of the Effective Date is a condition to
consummation of the Holding Company Merger. The opinions of Hunton & Williams
and Semmes, Bowen & Semmes are based on, and the opinions to be given as of the
Effective Date will be based on, certain customary assumptions and
representations regarding, among other things, the lack of previous dealings
between Citizens and Crestar, the existing and future ownership of Citizens
capital stock and Crestar capital stock and the future business plans for
Crestar.

     A Citizens shareholder who receives solely Crestar Common Stock (including
the associated Rights) in exchange for his shares of Citizens Common Stock will
not recognize any gain or loss on the exchange. If a shareholder receives
Crestar Common Stock and cash in lieu of a fractional share of Crestar Common
Stock, the shareholder will recognize taxable gain or loss solely with respect
to such cash as if the fractional share had been received and then redeemed for
the cash. A shareholder will have an aggregate tax basis in his shares of
Crestar Common Stock (including any fractional share interest) received in the
Holding Company Merger equal to his tax basis in the shares of Citizens Common
Stock exchanged therefor. A shareholder's holding period for shares of Crestar
Common Stock (including any fractional share interest) received in the Holding
Company Merger will include his holding period for the shares of Citizens Common
Stock exchanged therefor if they are held as a capital asset at the Effective
Time of the Holding Company Merger.
 
     THE PRECEDING DISCUSSION SUMMARIZES FOR GENERAL INFORMATION THE MATERIAL
FEDERAL INCOME TAX CONSEQUENCES OF THE HOLDING COMPANY MERGER TO CITIZENS
SHAREHOLDERS. IT DOES NOT DISCUSS ALL POTENTIALLY RELEVANT FEDERAL INCOME TAX
MATTERS OR CONSEQUENCES TO ANY FOREIGN OR OTHER SHAREHOLDERS SUBJECT TO SPECIAL
TAX TREATMENT, NOR DOES IT DISCUSS, AND NO OPINION HAS BEEN REQUESTED REGARDING,
ANY STATE OR LOCAL TAX CONSEQUENCES OF THE HOLDING COMPANY MERGER. THE TAX
CONSEQUENCES TO ANY PARTICULAR SHAREHOLDER MAY DEPEND ON THE SHAREHOLDER'S
INDIVIDUAL CIRCUMSTANCES. CITIZENS SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS WITH REGARD TO FEDERAL, STATE, AND LOCAL TAX CONSEQUENCES.

                              BUSINESS OF CRESTAR


     Crestar is the holding company for Crestar Bank, a Virginia banking
corporation. At September 30, 1996, Crestar had approximately $18.3 billion in
total assets, $13.6 billion in total deposits, and $1.4 billion in total
stockholders' equity.


     In 1963, six Virginia banks combined to form United Virginia Bankshares
Incorporated ("UVB"), a bank holding company formed under the Bank Holding
Company Act of 1956 (the "BHCA"). UVB (parent company of United Virginia Bank)
extended its operations into the District of Columbia by acquiring NS&T Bank,
N.A. on December 27, 1985 and into Maryland by acquiring Bank of Bethesda on
April 1, 1986. On September 1, 1987, UVB became Crestar Financial Corporation
and its Bank Subsidiaries adopted their present names.


     Crestar serves customers through a network of 380 banking offices and 387
automated teller machines (as of September 30, 1996). Crestar Bank offers a
broad range of banking services, including various types of deposit accounts and
instruments, commercial and consumer loans, trust and investment management
services, bank credit cards and international banking services. Crestar
Insurance Agency, Inc., offers a variety of personal and business insurance
products. Securities brokerage and investment banking services, including mutual
funds and annuities, are offered by Crestar Securities Corporation. Mortgage
loan origination, servicing and wholesale lending are offered by Crestar
Mortgage Corporation, and investment advisory services are offered by Capitoline
Investment Services Incorporated, both of which are subsidiaries of Crestar
Bank. These various Crestar subsidiaries provide banking and non-banking
services throughout Virginia, Maryland and Washington, D.C., as well as certain
non-banking services to customers in other states.


     The executive offices of Crestar are located in Richmond, Virginia at
Crestar Center, 919 East Main Street. Crestar's Operations Center is located in
Richmond. Regional headquarters are located in Norfolk and Roanoke, Virginia,
Washington, D.C., and Baltimore, Maryland.

RECENT DEVELOPMENTS

     SAIF LEGISLATION. Crestar's third quarter earnings were affected by two
special items relating to recently passed legislation regarding recapitalization
of the Savings Association Insurance Fund ("SAIF") and repeal of the thrift bad
debt recapture rule. Third quarter earnings were adversely affected by a
one-time assessment on deposits insured by the SAIF; as a result of several
thrift acquisitions during recent years, approximately 45% of Crestar's deposit
base are SAIF insured. The one-time assessment, on an after tax basis, was
approximately $22 million. As a result of this one-time assessment and based on
announced rate schedules, future earnings of Crestar are expected to be
augmented by a reduction in ongoing SAIF assessments of approximately $6 million
annually, on an after tax basis.

     Partially offsetting this one-time SAIF assessment, Crestar recognized a
one-time after tax gain of approximately $11 million in the third quarter as a
result of repeal of the tax law that required merging thrift institutions to
recapture into income pre-1988 loan loss reserves.

     The combined effect of the two special items resulted in an after tax
charge to third quarter earnings of $11 million, or $.25 per share.


     COMBINATION OF SUBSIDIARY BANKS. On November 14, 1996, Crestar combined its
subsidiary banks, Crestar Bank MD, Crestar Bank NA, and Crestar Bank (Virginia),
into one Virginia bank named Crestar Bank. A week earlier, Crestar Bank FSB had
been merged into Crestar Bank MD.


     The combination of its subsidiary banks into one bank is expected to
achieve synergies and other cost savings, although the savings will be modest
since Crestar, for a number of years, has for all practical purposes operated
its subsidiary banks as if they were one combined banking enterprise. The
combination of the subsidiary banks into a Virginia bank is not expected to have
any effect on the services or products offered to customers or any other
substantive change in the way Crestar does business.

                              BUSINESS OF CITIZENS


     Citizens is the holding company for Citizens Bank of Maryland. At September
30, 1996, Citizens had approximately $4.2 billion in total assets, $3.0 billion
in total deposits, and $354.6 million in total stockholders' equity.


     Citizens was formed in 1982 as the holding company for Citizens Bank of
Maryland. Citizens extended its operations into the District of Columbia by
acquiring McLachlen Bancshares on August 31, 1988, and into Virginia by
acquiring Arlington Bank on May 30, 1989.

                                       43

     Citizens serves customers through a network of 103 banking locations and
125 automated teller machines, as of September 30, 1996. Citizens Bank offers a

both retail and commercial customers. Citizens provides mortgage banking and
investment services through its subsidiary CitizensBanc Mortgage Co., Inc.,
Citizens Insurance Services, Inc., and Citizens Brokerage Services, Inc.

Maryland, Washington, D.C., and Northern Virginia.

     The payment of future dividends will be determined by Crestar's Board of
Directors in light of earnings, capital levels, cash requirements, Crestar's
financial condition and that of its subsidiaries, applicable government
regulations and policies and other factors deemed relevant by the Crestar Board,
including the amount of dividends payable to Crestar by its Bank Subsidiaries.
Various federal and state laws, regulations and policies limit the ability of
the Bank Subsidiaries to pay dividends to Crestar, which affects Crestar's
ability to pay dividends to shareholders. See "Supervision and Regulation."

                           SUPERVISION AND REGULATION
 
     Bank holding companies and banks operate in a highly regulated environment
and are regularly examined by federal and state regulators. The following
description briefly discusses certain provisions of federal and state laws and
certain regulations and the potential impact of such provisions on Crestar and
Citizens, and their respective bank subsidiaries. To the extent that the
following information describes statutory or regulatory provisions, it is
qualified in its entirety by reference to the particular statutory or regulatory
provisions.
 
BANK HOLDING COMPANIES
 
     As bank holding companies registered under the BHCA, Crestar and Citizens
are subject to regulation by the Federal Reserve Board. The Federal Reserve
Board has jurisdiction under the BHCA to approve any bank or nonbank
acquisition, merger or consolidation proposed by a bank holding company. The
BHCA generally limits the activities of a bank holding company and its
subsidiaries to that of banking, managing or controlling banks, or any other
activity which is so closely related to banking or to managing or controlling
banks as to be a proper incident thereto.
 
     The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
amended Section 3(d) of the BHCA by authorizing the FRB to approve on or after
September 29,1995 the acquisition by a bank holding company of more than 5% of
any class of the voting shares of, or substantially all the assets of, any bank
(or its holding company) located outside the
 
                                       47
 
<PAGE>
state in which the operations of such acquiring bank holding company's banking
subsidiaries are principally conducted on the date such company became a bank
holding company, regardless of whether the acquisition would be prohibited by
state law. Effective June 1, 1997, the law will allow interstate bank mergers,
subject to earlier "opt-in" or "opt-out" action by individual states. The law
also allows interstate branch acquisitions and de novo branching if permitted by
the host state. Virginia, Maryland and the District of Columbia have adopted
early "opt-in" legislation that allows interstate bank mergers. These laws also
permit interstate branch acquisitions and de novo branching in Virginia,
Maryland and the District of Columbia by out-of-state banks if reciprocal
treatment is accorded Virginia, Maryland or District of Columbia banks (as the
case may be) in the state of the acquiror or entrant.
 
     There are a number of obligations and restrictions imposed on bank holding
companies and their depository institution subsidiaries by federal law and
regulatory policy that are designed to reduce potential loss exposure to the
depositors of such depository institutions and to the FDIC insurance fund in the
event the depository institution becomes in danger of default or in default. For
example, under a policy of the Federal Reserve Board with respect to bank
holding company operations, a bank holding company is required to serve as a
source of financial strength to its subsidiary depository institutions and to
commit resources to support such institutions in circumstances where it might
not do so otherwise. In addition, the "cross-guarantee" provisions of federal
law require insured depository institutions under common control to reimburse
the FDIC for any loss suffered or reasonably anticipated by either the Savings
Association Insurance Fund ("SAIF") or the Bank Insurance Fund ("BIF") as a
result of the default of a commonly controlled insured depository institution or
for any assistance provided by the FDIC to a commonly controlled insured
depository institution in danger of default. The FDIC may decline to enforce the
cross-guarantee provisions if it determines that a waiver is in the best
interest of the SAIF or the BIF or both. The FDIC's claim for reimbursement is
superior to claims of shareholders of the insured depository institution or its
holding company but is subordinate to claims of depositors, secured creditors
and holders of subordinated debt (other than affiliates) of the commonly
controlled insured depository institution.
 
     Crestar is registered under the bank holding company laws of Virginia, and
Citizens under similar laws in Maryland. Accordingly, Crestar and its bank
subsidiaries are subject to further regulation and supervision by the State
Corporation Commission of Virginia, and Citizens and its bank subsidiaries by
the Division of Financial Regulation of the Maryland Department of Labor,
Licensing and Regulations.
 
CAPITAL REQUIREMENTS
 

     The Federal Reserve Board and the FDIC have issued substantially similar
risk-based and leverage capital guidelines applicable to banking organizations
they supervise. In addition, those regulatory agencies may from time to time
require that a banking organization maintain capital above the minimum levels
because of its financial condition or actual or anticipated growth. Under the
risk-based capital requirements of these federal bank regulatory agencies,
Crestar and Citizens each are required to maintain a minimum ratio of total
capital to risk-weighted assets of at least 8%. At least half of the total
capital is required to be "Tier 1 capital", which consists principally of common
and certain qualifying preferred stockholders' equity, less certain intangibles
and other adjustments. The remainder "Tier 2 capital" consists of a limited
amount of subordinated and other qualifying debt (including certain hybrid
capital instruments) and a limited amount of the general loan loss allowance.
The Tier 1 and total capital to risk-weighted asset ratios of Crestar as of
September 30, 1996 were 9.0% and 12.2% respectively, and of Citizens as of the
same date were 12.9% and 14.1%, respectively -- all exceeding the minimums
required.

 

     In addition, each of the federal regulatory agencies has established a
minimum leverage capital ratio (Tier 1 capital to average tangible assets).
These guidelines provide for a minimum ratio of 3% for banks and bank holding
companies that meet certain specified criteria, including that they have the
highest regulatory examination rating and are not contemplating significant
growth or expansion. All other institutions are expected to maintain a leverage
ratio of at least 100 to 200 basis points above the minimum. The Tier 1 capital
leverage ratio of Crestar as of September 30, 1996, was 7.5% and of Citizens at
the same date was 8.5%. The guidelines also provide that banking organizations
experiencing internal growth or making acquisitions will be expected to maintain
strong capital positions substantially above the minimum supervisory levels,
without significant reliance on intangible assets.

 
LIMITS ON DIVIDENDS AND OTHER PAYMENTS
 
     Crestar and Citizens are legal entities separate and distinct from their
Bank Subsidiaries. Most of the revenues of Crestar and Citizens come from
dividends paid by their respective Bank Subsidiaries. There are various
limitations applicable to the payment of dividends to Crestar and Citizens as
well as the payment of dividends by Crestar and Citizens to their respective
 
                                       48
 
<PAGE>

shareholders. Under federal law, prior approval from the bank regulatory
agencies is required if cash dividends declared by banks in any given year
exceed net income for that year plus retained earnings of the two preceding
years. Under these supervisory practices, at September 30, 1996, without
obtaining prior regulatory approval, Crestar Bank Subsidiaries could have paid
additional dividends of approximately $300 million to Crestar, and Citizens'
Bank Subsidiaries could have paid $76 million to Citizens. The payment of
dividends by Bank Subsidiaries, or Crestar or Citizens, may also be limited by
other factors, such as requirements to maintain capital above regulatory
guidelines. Bank regulatory agencies have authority to prohibit any bank or
holding company from engaging in an unsafe or unsound practice in conducting
their business. The payment of dividends, depending upon the financial condition
of the bank or holding company in question, could be deemed to constitute such
an unsafe or unsound practice. The Federal Reserve Board has stated that, as a
matter of prudent banking, a bank or bank holding company should not maintain
its existing rate of cash dividends on common stock unless (1) the
organization's net income available to common shareholders over the past year
has been sufficient to fund fully the dividends and (2) the prospective rate of
earnings retention appears consistent with the organization's capital needs,
asset quality, and overall financial condition.

 
SUBSIDIARY BANKS


     Crestar's and Citizens' Bank Subsidiaries are supervised and regularly
examined by the Federal Reserve Board, the FDIC, the SCC, the MBC and the Office
of the Comptroller of the Currency ("OCC"), as the case may be. The bank
subsidiaries are also subject to various requirements and restrictions under
federal and state law such as limitations on the types of services that they may
offer, the nature of investments that they may make, and the amounts of loans
that may be granted. Various consumer and compliance laws and regulations also
affect the operations of the Bank Subsidiaries. In addition to the impact of
regulation, the bank subsidiaries are affected significantly by actions of the
Federal Reserve Board in attempting to control the money supply and the
availability of credit.

 
     Each company's Bank Subsidiaries also are subject to the requirements of
the Community Reinvestment Act (the "CRA"). The CRA imposes on financial
institutions an affirmative and ongoing obligation to help meet the credit needs
of their local communities, including low- and moderate-income neighborhoods,
consistent with the safe and sound operation of those institutions. Each
financial institution's efforts in helping to meet community credit needs
currently are evaluated as part of the examination process pursuant to twelve
assessment factors. These factors also are considered in evaluating mergers,
acquisitions and applications to open branches. Each company's bank subsidiaries
have attained either an "outstanding" or "satisfactory" rating on their most
recent CRA performance evaluations.
 
     As institutions with deposits insured by BIF and/or SAIF, each company's
bank subsidiaries also are subject to insurance assessments imposed by the FDIC.
Legislation that became effective on September 30, 1996 assesses a one-time
charge on deposits insured by the Savings Association Insurance Fund (SAIF). As
a result of acquisition of thrift institutions in recent years, approximately
45% of Crestar's deposit base is SAIF-insured and, as the result, the one-time
charge assessed against Crestar on an after-tax basis is approximately $22
million. See "Business of Crestar -- Recent Development." This charge was
recognized in Crestar's publicly announced third quarter 1996 earnings and will
have the effect of significantly reducing future premiums payable into the SAIF.
All of Citizens deposits are insured by the Bank Insurance Fund (BIF), and
Citizens was not subject to this one-time charge.
 
OTHER SAFETY AND SOUNDNESS REGULATIONS
 
     The federal banking agencies have broad powers under current federal law to
take prompt corrective action to resolve problems of insured depository
institutions. The extent of these powers depends upon whether the institutions
in question are "well capitalized," "adequately capitalized,"
"undercapitalized," "significantly undercapitalized" or "critically
undercapitalized," as such terms are defined under uniform regulations defining
such capital levels issued by each of the federal banking agencies.
 
                      DESCRIPTION OF CRESTAR CAPITAL STOCK
 
     The capital stock of Crestar consists of 100,000,000 authorized shares of
Common Stock and 2,000,000 authorized shares of Preferred Stock. The shares of
Preferred Stock are issuable in series, with relative rights, preferences and
limitations of each series fixed by the Crestar Board. The following summary
does not purport to be complete and is subject in all respects to applicable
Virginia law, Crestar's Restated Articles of Incorporation (the "Crestar
Articles") and Bylaws, and the Rights Agreement dated June 23, 1989 (described
below) (the "Rights Agreement").
 
                                       49
 
<PAGE>
COMMON STOCK
 

     Crestar had 42,349,513 shares of Common Stock outstanding at September 30,
1996. Each share of Common Stock is entitled to one vote on all matters
submitted to a vote of shareholders. Holders of Common Stock are entitled to
receive dividends when and as declared by the Crestar Board out of funds legally
available therefor. Dividends may be paid on the Common Stock only if all
dividends on any outstanding Preferred Stock have been paid or provided for.

 
     The issued and outstanding shares of Common Stock are fully paid and
non-assessable. Holders of Common Stock have no preemptive or conversion rights
and are not subject to further calls or assessments by Crestar.
 
     In the event of the voluntary or involuntary dissolution, liquidation or
winding up of Crestar, holders of Common Stock are entitled to receive, pro
rata, after satisfaction in full of the prior rights of creditors and holders of
Preferred Stock, if any, all the remaining assets of Crestar available for
distribution.
 
     Directors are elected by a vote of the holders of Common Stock. Holders of
Common Stock are not entitled to cumulative voting rights. Chase Mellon
Shareholder Services acts as the transfer agent and registrar for the Common
Stock.
 
PREFERRED STOCK
 
     The Crestar Board is authorized to designate with respect to each new
series of Preferred Stock the number of shares in each series, the dividend
rates and dates of payment, voluntary and involuntary liquidation preferences,
redemption prices, whether or not dividends shall be cumulative and, if
cumulative, the date or dates from which the same shall be cumulative, the
sinking fund provisions, if any, for redemption or purchase of shares, the
rights, if any, and the terms and conditions on which shares can be converted
into or exchanged for, or the rights to purchase, shares of any other class or
series, and the voting rights, if any. Any Preferred Stock issued will rank
prior to the Common Stock as to dividends and as to distributions in the event
of liquidation, dissolution or winding up of Crestar. The ability of the Crestar
Board to issue Preferred Stock, while providing flexibility in connection with
possible acquisitions and other corporate purposes, could, among other things,
adversely affect the voting powers of holders of Common Stock and, under certain
circumstances, may discourage an attempt by others to gain control of Crestar.
 
     Pursuant to Crestar's Articles, the Crestar Board has designated a series
of 100,000 shares of Participating Cumulative Preferred Stock, Series C (the
"Series C Preferred Stock"), none of the shares of which are currently
outstanding. The Series C Preferred Stock was created in connection with
Crestar's shareholder rights plan which is described below.
 
RIGHTS
 
     In 1989, pursuant to the Rights Agreement, Crestar distributed as a
dividend one Right for each outstanding share of Common Stock. Each Right
entitles the holder to buy one one-thousandth of a share of Junior Preferred
Stock at an exercise price of $115, subject to adjustment. The Rights will
become exercisable only if a person or group acquires or announces a tender
offer for 10% or more of the outstanding Common Stock. When exercisable, Crestar
may issue a share of Common Stock in exchange for each Right other than those
held by such person or group. If a person or group acquires 30% or more of the
outstanding Common Stock, each Right will entitle the holder, other than the
acquiring person, upon payment of the exercise price, to acquire Series C
Preferred Stock or, at the option of Crestar, Common Stock, having a value equal
to twice the Right's exercise price. If Crestar is acquired in a merger or other
business combination or if 50% of its earnings power is sold, each Right will
entitle the holder, other than the acquiring person, to purchase securities of
the surviving company having a market value equal to twice the exercise price of
the Right. The Rights will expire on June 23, 1999, and may be redeemed by
Crestar at any time prior to the tenth day after an announcement that a 10%
position has been acquired, unless such time period has been extended by the
Crestar Board.
 
     Until such time as a person or group acquires or announces a tender offer
for 10% or more of the Common Stock, (i) the Rights will be evidenced by the
Common Stock certificates and will be transferred with and only with such Common
Stock certificates, and (ii) the surrender for transfer of any certificate for
Common Stock will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate. Rights may not be transferred,
directly or indirectly (i) to any person or group that has acquired, or obtained
the right to acquire, beneficial ownership of 10% or more of the Rights (an
"Acquiring Person"), (ii) to any person in connection with a transaction in
which such person becomes an Acquiring Person or (iii) to any affiliate or
associate of any such person. Any Right that is the subject of a purported
transfer to any such person will be null and void.
 
     The Rights can be expected to have certain anti-takeover effects if an
acquisition transaction not approved by the Crestar Board is proposed by a
person or group. In such event, the Rights will cause substantial dilution to
any person or group that
 
                                       50
 
<PAGE>
acquires more than 10% of the outstanding shares of Crestar Common Stock if
certain events thereafter occur without the Rights having been redeemed. For
example, if thereafter such acquiring person acquires 30% of Crestar's
outstanding Common Stock, or effects a business combination with Crestar, the
Rights permits shareholders to acquire securities having a value equal to twice
the amount of the purchase price specified in the Rights, but rights held by
such "acquiring person" are void to the extent permitted by law and may not be
exercised. Further, other shareholders may not transfer rights to such
"acquiring person" above his 10% ownership threshold. Because of these
provisions, it is unlikely that any person or group will propose an acquisition
transaction that is not approved by the Crestar Board. Thus, the Rights could
have the effect of discouraging acquisition transactions not approved by the
Crestar Board. The Rights do not interfere with any merger or other business
combination approved by the Crestar Board and shareholders because the rights
are redeemable with the concurrence of a majority of the "Continuing Directors,"
defined as directors in office when the Rights Agreement was adopted or any
person added thereafter to the Board with the approval of the Continuing
Directors.
 
VIRGINIA STOCK CORPORATION ACT
 
     The Virginia Stock Corporation Act ("VSCA") contains provisions governing
"Affiliated Transactions." These provisions, with several exceptions discussed
below, require approval of material acquisition transactions between a Virginia
corporation and any holder of more than 10% of any class of its outstanding
voting shares (an "Interested Stockholder") by the holders of at least
two-thirds of the remaining voting shares. Affiliated Transactions subject to
this approval requirement include mergers, share exchanges, material
dispositions of corporate assets not in the ordinary course of business, any
dissolution of the corporation proposed by or on behalf of an Interested
Stockholder, or any reclassification, including reverse stock splits,
recapitalization or merger of the corporation with its subsidiaries which
increases the percentage of voting shares owned beneficially by an Interested
Stockholder by more than 5%.
 
     For three years following the time that an Interested Stockholder becomes
an owner of 10% of the outstanding voting shares, a Virginia corporation cannot
engage in an Affiliated Transaction with such Interested Stockholder without
approval of two-thirds of the voting shares other than those shares beneficially
owned by the Interested Stockholder, and majority approval of the "Disinterested
Directors." A Disinterested Director means, with respect to a particular
Interested Stockholder, a member of the Crestar Board who was (1) a member on
the date on which an Interested Stockholder became an Interested Stockholder and
(2) recommended for election by, or was elected to fill a vacancy and received
the affirmative vote of, a majority of the Disinterested Directors then on the
Board. At the expiration of the three year period, the statute requires approval
of Affiliated Transactions by two-thirds of the voting shares other than those
beneficially owned by the Interested Stockholder.
 
     The principal exceptions to the special voting requirement apply to
transactions proposed after the three year period has expired and require either
that the transaction be approved by a majority of the corporation's
Disinterested Directors or that the transaction satisfy the fair-price
requirements of the statute. In general, the fair-price requirement provides
that in a two-step acquisition transaction, the Interested Stockholder must pay
the shareholders in the second step either the same amount of cash or the same
amount and type of consideration paid to acquire the Virginia corporation's
shares in the first step.
 
     None of the foregoing limitations and special voting requirements applies
to a transaction with an Interested Stockholder whose acquisition of shares
making such person an Interested Stockholder was approved by a majority of the
Virginia corporation's Disinterested Directors.

     These provisions were designed to deter certain takeovers of Virginia
corporations. In addition, the statute provides that, by affirmative vote of a
majority of the voting shares other than shares owned by any Interested
Stockholder, a corporation can adopt an amendment to its articles of
incorporation or bylaws providing that the Affiliated Transactions provisions
shall not apply to the corporation. Crestar has not "opted out" of the
Affiliated Transactions provisions.
 
     Virginia law also provides that shares acquired in a transaction that would
cause the acquiring person's voting strength to meet or exceed any of three
thresholds (20%, 33 1/3% or 50%) have no voting rights unless granted by a
majority vote of shares not owned by the acquiring person or any officer or
employee-director of the Virginia corporation. This provision empowers an
acquiring person to require the Virginia corporation to hold a special meeting
of shareholders to consider the matter within 50 days of its request.

                       COMPARATIVE RIGHTS OF SHAREHOLDERS
 
     At the Effective Time of the Holding Company Merger, shareholders of
Citizens automatically will become shareholders of Crestar, and their rights as
shareholders will be determined by the Crestar Articles and Crestar's Bylaws.
The following is a summary of the material differences in the rights of
shareholders of Crestar and Citizens.
 
CAPITALIZATION
 

     CITIZENS. The Citizens Charter authorizes the issuance of up to 125,000,000
shares of Citizens Common Stock, par value $2.50 per share, of which 15,133,099
shares were issued and outstanding as of the Record Date and 2,500,000 shares of
preferred stock, par value $10.00 per share, no shares of which were outstanding
as of the Record Date.

 
     CRESTAR. Crestar's authorized capital is set forth under "Description of
Crestar Capital Stock."
 
AMENDMENT OF ARTICLES OR BYLAWS
 
     CITIZENS. Any proposed amendment of the Citizens Articles must be approved
by the stockholders by the affirmative vote of two thirds of all the votes
entitled to cast on the amendment. Citizens' Bylaws generally provide that the
Citizens Board may, by majority vote, amend its Bylaws.
 
     CRESTAR. As permitted by the VSCA, the Crestar Articles provide that,
unless a greater vote is required by law, by the Crestar Articles or by a
resolution of the Crestar Board, the Crestar Articles may be amended if the
amendment is adopted by the Crestar Board and approved by a vote of the holders
of a majority of the votes entitled to be cast on the amendment by each voting
group entitled to vote thereon. To be amended, the Article providing for a
classified the Crestar Board and establishing criteria for removing Directors
requires the approving vote of a majority of "Disinterested Directors" and the
holders of at least two-thirds of the votes entitled to be cast on the
amendment.
 
     Crestar's Bylaws generally provide that the Crestar Board may, by a
majority vote, amend its Bylaws.
 
REQUIRED SHAREHOLDER VOTE FOR CERTAIN ACTIONS
 
     CITIZENS. Under Maryland law, a merger, consolidation or sale of
substantially all of the assets of Citizens can only be made when two-thirds of
the holders of the outstanding stock of the Company consent,unless the Company's
charter were to permit such action by less than a two-thirds vote. Citizens'
charter does not so provide.
 
     CRESTAR. The VSCA generally requires the approval of a majority of a
corporation's Board of Directors and the holders of more than two-thirds of all
the votes entitled to be cast thereon by each voting group entitled to vote on
any plan of merger or consolidation, plan of share exchange or sale of
substantially all of the assets of a corporation not in the ordinary course of
business. The VSCA also specifies additional voting requirements for Affiliated
Transactions and transactions that would cause an acquiring person's voting
power to meet or exceed specified thresholds, as discussed under "Description of
Crestar Capital Stock -- Virginia Stock Corporation Act."
 
     None of the additional voting requirements contained in the VSCA are
applicable to the Holding Company Merger since it is not an "Affiliated
Transaction."
 
DIRECTOR NOMINATIONS
 
     CITIZENS. Citizens' Bylaws do not provide a procedure for the nomination of
individuals to serve as directors.

     CRESTAR. The Bylaws of Crestar provide that any nomination for director
made by a shareholder must be made in writing to the Secretary of Crestar not
less than 15 days prior to the meeting of shareholders at which directors are to
be elected. If mailed, such notice shall be sent by certified mail, return
receipt requested, and shall be deemed to have been given when received by the
Secretary of Crestar. A shareholder's nomination for director shall set forth
(a) the name and business address of the shareholder's nominee, (b) the fact
that the nominee has consented to his name being placed in nomination, (c) the
name and address, as they appear on Crestar's books, of the shareholder making
the nomination, (d) the class and number of shares of Crestar's stock
beneficially owned by the shareholder, and (e) any material interest of the
shareholder in the proposed nomination.
 
                                       52
 
<PAGE>
DIRECTORS AND CLASSES OF DIRECTORS; VACANCIES AND REMOVAL OF DIRECTORS
 
     CITIZENS. The Citizens' Articles provides for three directors, but further
state that the number of directors may be increased or decreased pursuant to the
Bylaws. The Citizens' Articles provide that the directors shall be divided into
three classes with one class standing each year for election to a three year
term. The Citizens Bylaws provide that there shall be not less than five nor
more than 30 directors with the exact number of directors to be determined by a
majority resolution of the entire Board of Directors. The Citizens' Board
currently has fixed the number of directors at nine.
 
     The Citizens' Bylaws provide that any vacancy occurring on the Citizens'
Board, including a vacancy resulting from an increase from the number of
directors, may be filled by the affirmative vote of the majority of the
remaining directors. Directors so chosen hold office for the remainder of the
departed Director's term and until the departed Director's successor is elected
and qualified. Directors chosen due to an increase in the authorized number of
directors hold office until the next annual meeting of stockholders at which
directors are elected. No decrease in the number of directors constituting the
Citizens' Board shall shorten the term of any incumbent director.
 
     Citizens' Bylaws provide that the term of office of a Director of Citizens
shall expire upon the date of the Annual Meeting of Stockholders immediately
following the date upon which the Director reaches 70 years of age, unless the
Director had been elected at the 1988 Annual Meeting of Shareholders in which
case that Director was allowed to serve up to two additional terms if so
elected.

     Citizens' Articles and Bylaws do not provide for the removal of directors.
 
     CRESTAR. The Crestar Articles provide that the number of Directors shall be
set forth in the Bylaws, but the number of directors set forth in the Bylaws may
not be increased by more than four during any 12-month period except by the
affirmative vote of more than two-thirds of the votes entitled to be cast. The
Bylaws provide for a Board of Directors consisting of not less than five nor
more than 26 members, with the number to be fixed by the Board. The Crestar
Board currently has fixed the number of directors at 17. The Crestar Board is
divided into three classes, each as nearly equal in number as possible, with one
class being elected annually.
 
     The Crestar Articles provide that any vacancy occurring on the Crestar
Board, including a vacancy resulting from an increase in the number of
Directors, may be filled by the affirmative vote of a majority of the remaining
directors, though less than a quorum of the Crestar Board. If at the time any
such vacancy is filled, any person, or any associate or affiliate of such person
(as those terms are defined in Rule 12b-2 of the General Rules and Regulations
under the Exchange Act, or any successor rule or regulation) is directly or
indirectly the beneficial owner of 10% (or more) of outstanding voting shares,
the vacancy shall be filled by the affirmative vote of a majority of the
remaining directors in the class of directors in which the vacancy has occurred.
Directors so chosen shall hold office for a term expiring at the next following
annual meeting of shareholders at which directors are elected. No decrease in
the number of directors constituting the Crestar Board shall shorten the term of
any incumbent director.
 
     Subject to the rights of the holders of preferred stock then outstanding,
any director may be removed, with cause, only by the affirmative vote of the
holders of at least two-thirds of outstanding voting shares.
 
ANTI-TAKEOVER PROVISIONS
 
     CITIZENS. The MGCL prohibits certain "business combinations" (including a
merger, consolidation, share exchange, or, in certain circumstances, an asset
transfer or issuance or reclassification of equity securities) between a
Maryland corporation and an "Interested Stockholder." Interested Stockholders
are all persons (a) who beneficially own 10% or more of the voting power of the
corporation's shares or (b) an affiliate or associate of the corporation who, at
any time within the two-year period prior to the date in question, was an
Interested Stockholder or an affiliate or an associate thereof. Such business
combinations are prohibited for five years after the most recent date on which
the Interested Stockholder became an Interested Stockholder. Thereafter, any
such business combination must be recommended by the board of directors of such
corporation and approved by the affirmative vote of at least (a) 80% of the
votes entitled to be case by all holders of voting shares of the corporation,
and (b) 66 2/3% of the votes entitled to be cast by all holders of voting shares
of the corporation other than voting shares held by the Interested Stockholder
or an affiliate or associate of the Interested Stockholder, with whom the
business combination is to be effected, unless, among other things, the
corporation's stockholders receive a minimum price (as defined in the MGCL) for
their shares and the consideration is received in cash or in the same form as
previously paid by the Interested Stockholder for its shares. These provisions
of Maryland law do not apply, however, to business combinations that are
approved or exempted by the Board of Directors of the corporation prior to the
time that the Interested Stockholder becomes an Interested Stockholder. Crestar
and its affiliates and associates were exempted from these provisions of
Maryland
 
                                       53
 
<PAGE>
law by the Citizens Board. A Maryland corporation may adopt an amendment to its
charter electing not to be subject to the special voting requirements of the
foregoing legislation. Any such amendment would have to be approved by the
affirmative vote of at least 80% of the votes entitled to be cast by all holders
of outstanding shares of voting stock and 66 2/3% of the votes entitled to be
cast by holders of outstanding shares of voting stock who are not Interested
Stockholders.
 
     The MGCL provides the "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the matter,
excluding shares of stock owned by the acquiror or by officers or directors who
are employees of the corporation. Control shares are voting shares of stock
which, if aggregated with all other shares of stock previously acquired by such
a person, would entitle the acquiror to exercise voting power in electing
directors within one of the following ranges of voting power: (a) 20% or more
but less than 33 1/3%; (b) 33 1/3% or more but less than a majority; or (c) a
majority of all voting power. Control Shares do not include shares of stock an
acquiring person is entitled to vote as a result of having previously obtained
stockholder approval. A control share acquisition means, subject to certain
exceptions, the acquisition of, ownership of or the power to direct the exercise
of voting power with respect to, control shares.
 
     A person who has made or proposed to make a "control share acquisition,"
upon satisfaction of certain conditions (including an undertaking to pay
expenses), may compel the board of directors to call a special meeting of
shareholders to be held within 50 days of demand therefore to consider the
voting rights of the shares. If no request for a meeting is made, the
corporation may itself present the question at any shareholders' meeting.
 
     If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as permitted by the statute, then
subject to certain conditions and limitations, the corporation may redeem any or
all of the control shares (except those for which voting rights have previously
been approved) for fair value determined, without regard to voting rights, as of
the date of the last control share acquisition or of any meeting of shareholders
at which the voting rights of such shares are considered and not approved. If
voting rights for "control shares" are approved at a shareholders' meeting and
the acquiror becomes entitled to vote a majority of the shares entitled to vote,
all other shareholders may exercise appraisal rights. The fair value of the
stock as determined for purposes of such appraisal rights may not be less than
the highest price per share paid in the control share acquisition, and certain
limitations and restrictions otherwise applicable to the exercise of dissenters'
rights do not apply in the context of a "control share acquisition."
 
     The control share acquisition statute does not apply to stock acquired in a
merger, consolidation or stock exchange if the corporation is a party to the
transaction, or to acquisitions previously approved or exempted by a provision
in the charter or by-laws of the corporation.
 
     CRESTAR. For a description of certain provisions of VSCA which may be
deemed to have an anti-takeover effect, see "Description of Crestar Capital
Stock -- Virginia Stock Corporation Act."
 
PREEMPTIVE RIGHTS
 
     Neither the shareholders of Crestar nor the shareholders of Citizens have
preemptive rights. Thus, if additional shares of Crestar Common Stock, Crestar
Preferred Stock or Citizens Common Stock or Citizens Preferred Stock are issued,
holders of such stock, to the extent they do not participate in such additional
issuance of shares, would own proportionately smaller interests in a larger
amount of outstanding capital stock.
 
ASSESSMENT
 
     All outstanding shares of Citizens Common Stock are fully paid and
nonassessable.
 
     All shares of Crestar Common Stock presently issued are, and those to be
issued pursuant to the Agreement will be, fully paid and nonassessable.
 
CONVERSION; REDEMPTION; SINKING FUND
 
     Neither Crestar Common Stock nor Citizens Common Stock is convertible,
redeemable or entitled to any sinking fund.
 
LIQUIDATION RIGHTS
 
     CITIZENS. Maryland law generally provides that a corporation's board of
directors may propose dissolution for submission to shareholders and that to be
authorized, the dissolution must be approved by the holders of more than
two-thirds of all votes entitled to be cast on the proposal, unless the charter
of the corporation requires a greater or lesser vote.
 
                                       54
 
<PAGE>
     CRESTAR. The VSCA generally provides that a corporation's board of
directors may propose dissolution for submission to shareholders and that to be
authorized, the dissolution must be approved by the holders of more than
two-thirds of all votes entitled to be cast on the proposal, unless the articles
of incorporation of the corporation require a greater or lesser vote. There are
no provisions in the Crestar Articles which would modify the statutory
requirements for dissolution under the VSCA.
 
DIVIDENDS AND OTHER DISTRIBUTIONS
 
     CITIZENS. Maryland law permits the payment of dividends unless the
corporation would not be able to pay its debts as they become due in the usual
course of business or the corporation's total assets would be less than the sum
of the corporation's total liabilities plus, unless the charter permits
otherwise, the amount that would be needed, if the corporation were to be
dissolved at the time of such dividends, to satisfy the preferential rights upon
dissolution of shareholders whose preferential rights on dissolution are
superior to those receiving the dividends.
 
     CRESTAR. The VSCA generally provides that a corporation may make
distributions to its shareholders unless, after giving effect to the
distribution, (i) the corporation would not be able to pay its debts as they
become due in the usual course of business or (ii) the corporation's total
assets would be less than the sum of its total liabilities plus (unless the
articles of incorporation permit otherwise, which the Crestar Articles do not)
the amount that would be needed, if the corporation were to be dissolved at the
time of the distribution, to satisfy the preferential rights upon dissolution of
shareholders whose preferential rights are superior to those receiving the
distribution. These requirements are applicable to Crestar as a Virginia
corporation.
 
     In addition to the limitations set forth in the VSCA, there are various
regulatory requirements which are applicable to distributions by bank holding
companies such as Crestar and Citizens. For a description of the regulatory
limitations on distributions, see "Supervision and Regulation -- Limits on
Dividends and Other Payments."
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
     CITIZENS. A special meeting of the shareholders of Citizens may be called
by the Chairman of the Citizens Board or the President, by a majority of the
Citizens Board or by shareholders entitled to cast at least 25% of the votes at
such meeting. However, Maryland law provides that a special meeting need not be
called to consider any matter which is substantially the same as a matter voted
on at any special meeting of shareholders held during the preceding 12 months
unless the meeting is requested by shareholders entitled to cast a majority of
all the votes entitled to be cast at the meeting.
 
     CRESTAR. The Bylaws of Crestar provide that special meetings of the
shareholders for any purpose or purposes may be called at any time by the
Chairman of the Crestar Board, by the President, or by a majority of the Crestar
Board.
 
INDEMNIFICATION
 
     CITIZENS. The Citizens' Articles provide that each director and officer
shall be indemnified to the full extent permitted by the MGCL and that no
director or officer shall be personally liable to Citizens for money damages.
 
     The Citizens' Bylaws provide that any individual who is serving as a
director, officer, employee or agent of Citizens who is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative, shall be indemnified
and held harmless by Citizens to the fullest extent authorized by MGCL.
 
     The MGCL permits a corporation to indemnify its directors and officers,
among others, against judgments, penalties, fines, settlements and reasonable
expenses actually incurred by them in connection with any proceeding to which
they may be made a party by reason of their service in those or other
capacities, unless it is established that (a) the act or omission of the
director or officer was material to the matter giving rise to such proceeding
and (i) was committed in bad faith or (ii) was the result of active and
deliberate dishonesty, (b) the director or officer actually received an improper
personal benefit in money, property or services, or (c) in the case of any
criminal proceeding, the director or officer had reasonably cause to believe
that the action or omission was unlawful.
 
     CRESTAR. The Crestar Articles provide that to the full extent permitted by
the VSCA and any other applicable law, Crestar shall indemnify a director or
officer of Crestar who is or was a party to any proceeding by reason of the fact
that he is or was such a director or officer or is or was serving at the request
of the corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise. The Crestar Board is empowered, by majority vote of a quorum
of disinterested directors, to contract in advance to indemnify any director or
officer.
 
                                       55
 
<PAGE>
SHAREHOLDER PROPOSALS
 
     CITIZENS. Citizens' Bylaws do not have any provision for shareholder
proposals.
 
     CRESTAR. The Bylaws of Crestar provide that at any meeting of shareholders
of Crestar, only that business that is properly brought before the meeting may
be presented to and acted upon by the shareholders. To be properly brought
before the meeting, business must be brought (a) by or at the direction of the
Crestar Board or (b) by a shareholder who has given written notice of business
he expects to bring before the meeting to the Secretary of Crestar not less than
15 days prior to the meeting. If mailed, such notice shall be sent by certified
mail, return receipt requested, and shall be deemed to have been given when
received by the Secretary of Crestar. A shareholder's notice to the Secretary
shall set forth as to each matter the shareholder proposes to bring before the
meeting (a) a brief description of the business to be brought before the meeting
and the reasons for conducting such business at the meeting, (b) the name and
address, as they appear on Crestar's books, of the shareholder proposing such
business, (c) the class and number of shares of Crestar's stock beneficially
owned by the shareholder, and (d) any material interest of the shareholder in
such business. No business shall be conducted at a meeting of shareholders
except in accordance with the procedures set forth in Crestar's Bylaws.
 
SHAREHOLDER INSPECTION RIGHTS; SHAREHOLDER LISTS
 
     CITIZENS. Under Maryland law, any shareholder has the right to inspect and
copy the by-laws, minutes of the proceedings of shareholders, annual statement
of affairs, and voting trust agreements on file at the corporation's principal
office. Maryland law also provides that one or more persons who together have
been shareholders of record for at least six months and who together hold at
least 5% of the outstanding stock of any class may inspect and copy the
corporation's books of account, stock ledger and shareholders' list and may
require the corporation to produce a verified statement of affairs.
 
     CRESTAR. Under the VSCA, the shareholder of a Virginia corporation is
entitled to inspect and copy certain books and records, including the articles
of incorporation and bylaws of the corporation if he gives the corporation
written notice of his demand at least five business days before the date on
which he wishes to inspect and copy. The shareholder of a Virginia corporation
is entitled to inspect and copy certain other books and records, including a
list of shareholders, minutes of any meeting of the board of directors and
accounting records of the corporation, if (i) the shareholder has been a
shareholder of record for at least six months immediately preceding his or her
written demand or is the holder of at least 5% of the corporation's outstanding
shares, (ii) the shareholder's demand is made in good faith and for a proper
purpose, (iii) the shareholder describes with reasonable particularity the
purpose of the request and the records desired to be inspected and (iv) the
records are directly connected with the stated purpose, and if he gives the
corporation written notice of his demand at least five business days before the
date on which he wishes to inspect and copy. The VSCA also provides that a
corporation shall make available for inspection by any shareholder during usual
business hours, at least 10 days before each meeting of shareholders, a complete
list of the shareholders entitled to vote at such meeting.
 
SHAREHOLDER RIGHTS PLAN
 
     CITIZENS. On May 10, 1989, shareholders of Citizens Bancorp adopted a
Rights Plan which provides for substantial dilution to a person or group that
attempts to acquire Citizens on terms not approved by the Company's Board of
Directors, except in the event of an acquisition of at least 80% of the
outstanding Common Stock solely pursuant to a tender offer for all outstanding
shares at a uniform cash price open equally to all stockholders other than such
acquiring person or group. Citizens anticipates that it will amend the terms of
the Rights Plan so that the Plan will be terminated contemporaneously with the
closing contemplated by the Agreement.
 
     CRESTAR. For a description of a shareholder rights plan which has been
adopted by Crestar, see "Description of Crestar Capital Stock -- Rights."
 
DISSENTERS' RIGHTS
 
     CITIZENS. The provisions of Title 3 of the MGCL, which provide shareholders
of a Maryland corporation the right to demand and receive payment of the fair
value of their shares in the event of mergers, consolidations and certain other
corporate transactions, are applicable to Citizens as a Maryland corporation.
However, because Citizens Common Stock is designated as a national market system
security on an interdealer quotation system by the National Association of
Securities Dealers, Inc., shareholders of Citizens generally do not have rights
to demand and receive payment of the fair value of their shares in the event of
mergers, consolidations and certain other corporate transactions to which
Citizens is a party.
 
                                       56
 
<PAGE>
     CRESTAR. The provisions of Article 15 of the VSCA which provide
shareholders of a Virginia corporation the right to dissent from, and obtain
payment of the fair value of their shares in the event of, mergers,
consolidations and certain other corporate transactions are applicable to
Crestar as a Virginia corporation. However, because Crestar has more than 2,000
record shareholders, shareholders of Crestar generally do not have rights to
dissent from mergers, consolidations and certain other corporate transactions to
which Crestar is a party because Article 15 of the VSCA provides that holders of
shares of a Virginia corporation which has shares listed on a national
securities exchange or which has at least 2,000 record shareholders are not
entitled to dissenters' rights unless certain requirements are met.
 
                         RESALE OF CRESTAR COMMON STOCK
 
     Crestar Common Stock has been registered under the 1933 Act, thereby
allowing such shares to be traded freely and without restriction by those
holders of Citizens Common Stock who receive such shares following consummation
of the Holding Company Merger and who are not deemed to be "affiliates" (as
defined under the 1933 Act, but generally including directors, certain executive
officers and 10% or more shareholders) of Citizens or Crestar. Each holder of
Citizens Common Stock who is deemed by Citizens to be an affiliate of it has
entered into an agreement with Crestar prior to the Effective Date of the
Holding Company Merger providing, among other things, that (A) such affiliate
acknowledges and agrees to support and vote such shares of Citizens Common Stock
beneficially owned by him to ratify and confirm the Agreement and the Holding
Company Merger, (B) such affiliate acknowledges and agrees beginning 30 days
prior to the Effective Date, that he will not sell, pledge, transfer or
otherwise dispose of shares of Citizens Common Stock or Crestar Common Stock
except in compliance with the applicable provisions of the 1933 Act and rules
and regulations thereunder and until such time as financial results covering at
least 30 days of combined operations of Crestar and Citizens have been published
within the meaning of Section 201.01 of the SEC's Codification of Financial
Reporting Policies, and (C) the certificates representing said shares may bear a
legend referring to the foregoing restrictions. This Joint Proxy
Statement/Prospectus does not cover any resales of Crestar Common Stock received
by affiliates of Citizens.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     This Agreement and Plan of Reorganization (the "Agreement") dated as of
September 15, 1996 among CRESTAR FINANCIAL CORPORATION, a Virginia corporation
("Crestar"), CDM ACQUISITION SUBSIDIARY, INC., a Maryland corporation
("Subsidiary"), CRESTAR BANK DC, a Virginia banking corporation wholly-owned by
Crestar ("Crestar Bank"), CITIZENS BANCORP, a Maryland corporation ("Citizens")
and CITIZENS BANK OF MARYLAND, a Maryland banking corporation wholly-owned by
Citizens ("Citizens Bank" which term, for the purposes of this Agreement and
where the context requires, includes its subsidiaries), recites and provides:
 
     A. Citizens and Crestar have reached agreement pursuant to which Crestar
will acquire Citizens in a statutory merger in exchange for Crestar Common
Stock.
 
     B. The boards of directors of Crestar and Citizens deem it advisable to
merge Subsidiary into Citizens (the "Holding Company Merger") pursuant to this
Agreement and the Plan of Merger attached as Exhibit A (the "Holding Company
Plan of Merger") whereby the holders of shares of common stock ("Citizens Common
Stock") will receive common stock of Crestar ("Crestar Common Stock") in
exchange therefor.
 
     C. To effectuate the foregoing, the parties desire to adopt this Agreement
and the Holding Company Plan of Merger, which shall represent a plan of
reorganization in accordance with the provisions of Section 368(a) of the United
States Internal Revenue Code, as amended (the "Code").
 
     D. Simultaneously with the execution of this Agreement, Citizens and
Crestar are entering into a Stock Option Agreement (the "Option Agreement")
pursuant to which Citizen is granting an option to Crestar to purchase shares of
Citizens Common Stock in accordance with the terms of such Agreement.
 
     NOW, THEREFORE, in consideration of the mutual benefits to be derived from
this Agreement, and of the representations, warranties, conditions and promises
herein contained, Crestar, Crestar Bank, Subsidiary, Citizens and Citizens Bank
hereby adopt this Agreement whereby at the "Effective Time of the Holding
Company Merger" (as defined in Article VI hereof) Subsidiary shall be merged
into Citizens in accordance with the Holding Company Plan of Merger. The
outstanding shares of Citizens Common Stock shall be converted into shares of
Crestar Common Stock as provided in this Agreement on the basis, terms and
conditions contained herein and in the Holding Company Plan of Merger.
 
     In connection therewith, the parties hereto agree as follows:
 
                                   ARTICLE I
                                    GENERAL
 
     1.1. HOLDING COMPANY MERGER. Subject to the provisions of this Agreement
and the Holding Company Plan of Merger, at the Effective Time of the Holding
Company Merger the separate existence of Subsidiary shall cease and Subsidiary
shall be merged with and into Citizens (the "Surviving Company").
 
     1.2. ISSUANCE OF CRESTAR COMMON STOCK. Crestar agrees that at the Effective
Time of the Holding Company Merger it will issue Crestar Common Stock to the
extent set forth in, and in accordance with, the terms of this Agreement and the
Holding Company Plan of Merger.
 
     1.3. TAKING OF NECESSARY ACTION. In case at any time after the Effective
Time of the Holding Company Merger any further action is necessary or desirable
to carry out the purposes of this Agreement and to vest the Surviving Company
with full title to all properties, assets, rights, approvals, immunities and
franchises of Subsidiary, the officers and directors of the Surviving Company
shall take all such necessary action.
 
                                   ARTICLE II
                 EFFECT OF TRANSACTION ON COMMON STOCK, ASSETS,
                   LIABILITIES AND CAPITALIZATION OF CRESTAR,
                    CRESTAR BANK, CITIZENS AND CITIZENS BANK
 
     2.1. CONVERSION OF STOCK; EXCHANGE RATIO. At the Effective Time of the
Holding Company Merger:
 
          (a) CONVERSION OF STOCK. Each share of Citizens Common Stock which is
     issued and outstanding at the Effective Time of the Holding Company Merger
     (other than shares held directly by Crestar, which shall be canceled
     without payment therefore) shall, and without any action by the holder
     thereof, be converted into the number of shares of Crestar
 
                                      I-6
 
<PAGE>
     Common Stock determined in accordance with subsection 2.1(b). All such
     shares shall be validly issued, fully paid and nonassessable.
 
          (b) EXCHANGE RATIO. Each share of Citizens Common Stock (other than
     shares held directly by Crestar and Dissenting Shares) shall be converted
     into 0.835 shares of Crestar Common Stock (the "Exchange Ratio").
 
          The Exchange Ratio at the Effective Time of the Holding Company Merger
     shall be adjusted to reflect any consolidation, split-up, other
     subdivisions or combinations of Crestar Common Stock, any dividend payable
     in Crestar Common Stock, or any capital reorganization involving the
     reclassification of Crestar Common Stock subsequent to the date of this
     Agreement.
 
     2.2. MANNER OF EXCHANGE.
 
          (a) After the Effective Time of the Holding Company Merger, each
     holder of a certificate for theretofore outstanding shares of Citizens
     Common Stock, upon surrender of such certificate to Crestar Bank (which
     shall act as exchange agent), accompanied by a Letter of Transmittal, which
     shall be mailed to each holder of a certificate for theretofore outstanding
     shares of Citizens Common Stock by Crestar Bank promptly following the
     Effective Time of the Holding Company Merger, shall be entitled to receive
     in exchange therefor a certificate or certificates representing the number
     of full shares of Crestar Common Stock for which shares of Citizens Common
     Stock theretofore represented by the certificate or certificates so
     surrendered shall have been exchanged as provided in this Article II. Until
     so surrendered, each outstanding certificate which, prior to the Effective
     Time of the Holding Company Merger, represented Citizens Common Stock will
     be deemed to evidence the right to receive the number of full shares of
     Crestar Common Stock into which the shares of Citizens Common Stock
     represented thereby may be converted in accordance with the Exchange Ratio;
     and, after the Effective Time of the Holding Company Merger will be deemed
     for all corporate purposes of Crestar to evidence ownership of the number
     of full shares of Crestar Common Stock into which the shares of Citizens
     Common Stock represented thereby were converted.
 
          (b) Until such outstanding certificates formerly representing Citizens
     Common Stock are surrendered, no dividend payable to holders of record of
     Crestar Common Stock for any period as of any date subsequent to the
     Effective Time of the Holding Company Merger shall be paid to the holder of
     such outstanding certificates in respect thereof. After the Effective Time
     of the Holding Company Merger, there shall be no further registry of
     transfer on the records of Citizens of shares of Citizens Common Stock. If
     a certificate representing such shares is presented to Crestar, it shall be
     canceled and exchanged for a certificate representing shares of Crestar
     Common Stock as herein provided. Upon surrender of certificates of Citizens
     Common Stock in exchange for Crestar Common Stock, there shall be paid to
     the recordholder of the certificates of Crestar Common Stock issued in
     exchange therefor (i) the amount of dividends theretofore paid for such
     full shares of Crestar Common Stock as of any date subsequent to the
     Effective Time of the Holding Company Merger which have not yet been paid
     to a public official pursuant to abandoned property laws and (ii) at the
     appropriate payment date the amount of dividends with a record date after
     the Effective Time of the Holding Company Merger but prior to surrender and
     a payment date subsequent to surrender. No interest shall be payable on
     such dividends upon surrender of outstanding certificates.
 
          (c) At the Effective Time of the Holding Company Merger, each share of
     Citizens Common Stock held by Crestar shall be canceled, retired and cease
     to exist.
 
          (d) At the Effective Time of the Holding Company Merger, each share of
     Subsidiary Common Stock shall be converted into one share of common stock
     of the Surviving Corporation.
 
          (e) At the Effective Time of the Holding Company Merger and as
     provided in the Holding Company Plan of Merger, outstanding options to
     acquire Citizens Common Stock that were granted under Citizens' 1986 Stock
     Incentive Plan and 1988 Stock Option Plan ("Citizens Options," as defined
     in Section 3.1(j)(1) hereof), and which are identified on Schedule C,
     shall, be converted, based on the Exchange Ratio, into options to acquire
     Crestar Common Stock ("Crestar Options"). The exercise price per share of
     Crestar Common Stock under a Crestar Option shall be equal to the exercise
     price per share of Citizens Common Stock under the Citizens Option divided
     by the Exchange Ratio (rounded up to the nearest cent). The number of
     shares of Crestar Common Stock subject to a Crestar Option shall be equal
     to the number of shares of Citizens Common Stock subject to the Citizens
     Option multiplied by the Exchange Ratio (rounded down to the nearest whole
     share). Except as provided in the preceding sentences regarding the price
     of, and number of shares of Crestar Common Stock subject to, the Crestar
     Option, the terms of the Crestar Option shall be the same as the terms of
     the Citizens Option.
 
                                      I-7
 
<PAGE>
     2.3. NO FRACTIONAL SHARES. No certificates or scrip for fractional shares
of Crestar Common Stock will be issued. In lieu thereof, Crestar will pay the
value of such fractional shares in cash on the basis of the Average Closing
Price as defined in Section 7.1(h).
 
     2.4. DISSENTING SHARES. Pursuant to Section 3-202 of the Maryland General
Corporation Law ("MGCL"), shareholders of Citizens do not have dissenter's
rights in the Holding Company Merger.
 
     2.5. ASSETS. At the Effective Time of the Holding Company Merger, the
corporate existence of Subsidiary shall be merged into and continued in Citizens
as the Surviving Company. All rights, franchises and interests of Subsidiary in
and to any type of property and choses in action shall be transferred to and
vested in the Surviving Company, by virtue of the Holding Company Merger without
any deed or other transfer. The Surviving Company without any order or other
action on the part of any court or otherwise, shall hold and enjoy all rights of
property, franchises and interests, including appointments, designations and
nominations, and all other rights and interests as trustee, executor,
administrator, transfer agent or registrar of stocks and bonds, guardian of
estates, assignee, receiver and committee, and in every other fiduciary
capacity, in the same manner and to the same extent as such rights, franchises
and interests were held or enjoyed by Citizens at the Effective Time of the
Holding Company Merger, as provided in Section 3-114 of the MGCL.
 
     2.6. LIABILITIES. At the Effective Time of the Holding Company Merger, the
Surviving Company shall be liable for all liabilities of Subsidiary. All
deposits, debts, liabilities and obligations of Subsidiary accrued, absolute,
contingent or otherwise, and whether or not reflected or reserved against on
balance sheets, books of accounts, or records of Subsidiary shall be those of
the Surviving Company and shall not be released or impaired by the Holding
Company Merger. All rights of creditors and other obligees and all liens on
property of Subsidiary shall be preserved unimpaired.
 
                                  ARTICLE III

     delivery of this Agreement, the consummation of the transactions
     contemplated hereby and by the Holding Company Plan of Merger and
     compliance by Citizens with any of the provisions hereof or thereof will
     not (i) conflict with or result in a breach of any provision of its

     right of termination, cancellation or acceleration) under any of the terms,
     conditions or provisions of any note, bond, debenture, mortgage, indenture,
     license, material agreement or other material instrument or obligation to
     which Citizens is a party, or by which it or any of its properties or
     assets may be bound, or (ii) violate any order, writ, injunction, decree,
     statute, rule or regulation applicable to Citizens or any of its properties
     or assets. No consent or approval by any governmental authority, other than
     compliance with applicable federal and state securities and banking laws,
     and laws administered by and regulations of the Board of Governors of the
     Federal Reserve System (the "Federal Reserve Board"), the Federal Deposit
     Insurance Corporation (the "FDIC"), the Division of Financial Regulation of
     the Maryland Department of Labor, Licensing and Regulation (the "Maryland

     Citizens of this Agreement or the consummation by Citizens of the
     transactions contemplated hereby or by the Holding Company Plan of Merger.

     record and beneficially are free and clear of all mortgages, liens,
     pledges, encumbrances or any other restriction, whether contractual or
     statutory, which would materially impair the ability of Citizens or
     Citizens Bank freely to dispose of any such security at any time, except as
     noted on Schedule A. Any securities owned of record by Citizens and
     Citizens Bank in an amount equal to 5% or more of the issued and
     outstanding voting securities of the issuer thereof have been noted on such
     Schedule A. There are no voting trusts or other agreements or undertakings
     of which Citizens or Citizens Bank is a party with respect to the voting of

     valid, perfected first lien or security interest in the government
     securities or other collateral securing the repurchase agreement, and the
     value of the collateral securing each such repurchase agreement equals or
     exceeds the amount of the debt secured by such collateral under such
     agreement.
 
          (e) FINANCIAL STATEMENTS. Schedule B contains copies of the following
     financial statements of Citizens (the "Citizens Financial Statements"):
 
             (i) Consolidated Statement of Financial Condition as of June 30,
        1996 and 1995 (unaudited) and as of December 31, 1995 and 1994
        (audited);

             (ii) Consolidated Statements of Operations for the three and six
        month periods ended June 30, 1996 and 1995 (unaudited) and each of the
        three years ended December 31, 1995, 1994, and 1993 (audited);
 
             (iii) Consolidated Statements of Changes in Stockholders' Equity
        for the three and six month periods ended June 30, 1996 and 1995
        (unaudited) and each of the three years ended December 31, 1995, 1994
        and 1993 (audited); and
 
             (iv) Consolidated Statements of Cash Flows for the three and six
        month periods ended June 30, 1996 and 1995 (unaudited) and each of the
        three years ended December 31, 1995, 1994 and 1993 (audited).
 
                                      I-9
 
<PAGE>
          Such financial statements and the notes thereto have been prepared in
     accordance with generally accepted accounting principles applied on a
     consistent basis throughout the periods indicated unless otherwise noted in
     the Citizens Consolidated Financial Statements. Each of such consolidated
     statements of financial condition, together with the notes thereto,
     presents fairly as of its date the consolidated financial condition and
     assets and liabilities of Citizens. The consolidated statements of
     operations, changes in stockholders' equity and cash flows, together with
     the notes thereto, present fairly the results of consolidated operations,
     consolidated changes in stockholders' equity and consolidated cash flows of
     Citizens or Citizens Bank for the periods indicated in accordance with
     generally accepted accounting principles ("GAAP").
 
          (f) ABSENCE OF UNDISCLOSED LIABILITIES. At June 30, 1996, and December
     31, 1995 Citizens had no material obligations or liabilities (contingent or
     otherwise) of any nature which were not reflected in the Citizens Financial
     Statements or in the Citizens periodic reports filed with the Securities
     and Exchange Commission ("SEC") under the Securities Exchange Act of 1934
     (the "1934 Act") as of such dates, or disclosed in the notes thereto,
     except for those which are disclosed in Schedules specifically referred to
     herein or which in the aggregate are immaterial.
 
          (g) TAX MATTERS. Citizens Bank and all other subsidiaries of Citizens
     are members of the same "affiliated group," (as defined in Section
     1504(a)(1) of the Code) as Citizens (collectively, the "Citizens Group"),
     the Citizens Group files a consolidated federal income tax return, and
     except as disclosed in Schedule C, no member of the Citizens Group has ever
     filed a consolidated federal income tax return with (or been included in a
     consolidated return of) any other affiliated group. Each member of the
     Citizens Group has filed or caused to be filed or (in the case of returns
     or reports not yet due) will file all tax returns and reports required to
     have been filed by or for them before the Effective Time of the Holding
     Company Merger, and all information set forth in such returns or reports is
     or (in the case of such returns or reports not yet due) will be accurate
     and complete in all material respects. Each member of the Citizens Group
     has paid or made adequate provision for, or (with respect to returns or
     reports not yet filed) before the Effective Time of the Holding Company
     Merger will pay or make adequate provision for, all taxes, additions to
     tax, penalties, and interest for all periods covered by those returns or
     reports. There are, and at the Effective Time of the Holding Company Merger
     will be, no unpaid taxes, additions to tax, penalties, or interest due and
     payable by any member of the Citizens Group that are or could become a lien
     on any asset, or otherwise materially adversely affect the business,
     property or financial condition, of any member of the Citizens Group except
     for taxes and any such related liability (a) incurred in the ordinary
     course of business for which adequate provision has been made by any member
     of the Citizens Group or (b) being contested in good faith and disclosed in
     Schedule C. Each member of the Citizens Group has collected or withheld, or
     will collect or withhold before the Effective Time of the Holding Company
     Merger, all amounts required to be collected or withheld by it for any
     taxes, and all such amounts have been, or before the Effective Time of the
     Holding Company Merger will have been, paid to the appropriate governmental
     agencies or set aside in appropriate accounts for future payment when due.
     Each member of the Citizens Group is in material compliance with, and its
     records contain all information and documents (including, without
     limitation, properly completed IRS Forms W-9) necessary to comply in all
     material respects with, all applicable information reporting and tax
     withholding requirements under federal, state, and local laws, rules, and
     regulations, and such records identify with specificity all accounts
     subject to backup withholding under Section 3406 of the Code. The
     consolidated statements of financial condition contained in the Citizens
     Financial Statements fully and properly reflect, as of the dates thereof,
     the aggregate liabilities of the members of the Citizens Group for all
     accrued taxes, additions to tax, penalties and interest in accordance with
     GAAP. For periods ending after June 30, 1996, the books and records of each
     member of the Citizens Group fully and properly reflect their liability for
     all accrued taxes, additions to tax, penalties and interest in accordance
     with GAAP. Except as disclosed in Schedule C, no member of the Citizens
     Group has granted (nor is it subject to) any waiver of the period of
     limitations for the assessment of tax for any currently open taxable
     period, no unpaid tax deficiency has been asserted in writing against or
     with respect to any member of the Citizens Group by any taxing authority,
     and there is no currently pending examination or other administrative
     proceeding or any judicial proceeding relating to any tax (including any
     refund thereof) of any member of the Citizens Group. No member of the
     Citizens Group has made or entered into, or holds any asset subject to, a
     consent filed pursuant to Section 341(f) of the Code and the regulations
     thereunder or a "safe harbor lease"subject to former Section 168(f)(8) of
     the Code and the regulations thereunder. Except as disclosed in Schedule C,
     no member of the Citizens Group is obligated to make, or is a party to an
     agreement that could obligate it to make, any payment that would not be
     deductible by reason of Section 162(m) or 280G of the Code. Schedule C
     describes all material tax elections, consents and agreements affecting any
     member of the Citizens Group and lists all types of material taxes paid and
     tax returns filed by or on behalf of each member of the Citizens Group. To
     the best knowledge of Citizens, no Citizens shareholder is a "foreign
     person" for purposes of Section 1445 of the Code.

     forth on Schedule I, no such proceeding or investigation, if decided
     adversely, would have a material adverse effect on either the financial
     condition, results of operations or business of Citizens on a consolidated
     basis. Except as set forth in Schedule I, Citizens and Citizens Bank have
     complied in all material respects with any laws, ordinances, requirements,
     regulations or orders applicable to its business except where noncompliance
     would not have a material adverse effect on either the financial condition,
     results of operations or business of Citizens on a consolidated basis.
     Citizens and Citizens Bank have all licenses, permits, orders or approvals
     (collectively, the "Permits") of any federal, state, local or foreign
     governmental or regulatory body that are necessary for the conduct of its
     business and the absence of which would have a material adverse effect on
     the financial condition, results of operations or business of Citizens on a
     consolidated basis; the Permits are in full force and effect; no violations
     are or have been recorded in respect of any Permits nor has Citizens or

     decree which materially adversely affects, or might reasonably be expected
     materially adversely to affect either the financial condition, results of
     operations, or business of Citizens on a consolidated basis.
 
          (m) EMPLOYEE BENEFIT PLANS.
 
             (1) Schedule F includes a correct and complete list of, and Crestar
        has been furnished a true and correct copy of (or an accurate written
        description thereof in the case of oral agreements or arrangements) (A)
        all qualified pension and profit-sharing plans, all deferred
        compensation, consultant, severance, thrift, option, bonus and group
        insurance contracts and all other incentive, welfare and employee
        benefit plans, trust, annuity or other funding agreements, and all other
        agreements (including oral agreements) that are presently in effect, or
        have been approved prior to the date hereof, maintained for the benefit
        of employees or former employees of Citizens or Citizens Bank or the
        dependents or beneficiaries of any employee or former employee of
        Citizens or Citizens Bank, whether or not subject to ERISA (the
        "Employee Plans"), (B) the most recent actuarial and financial reports
        prepared or required to be prepared with respect to any Employee Plan
        and (C) the most recent annual reports filed with any governmental
        agency, the most recent favorable determination letter issued by the
        Internal Revenue Service, and any open requests for rulings or
        determination letters, that pertain to any such qualified Employee Plan.
        Schedule F identifies each Employee Plan that is intended to be
        qualified under Section 401(a) of the Code and each such plan is
        qualified.
 
             (2) Neither Citizens, Citizens Bank nor any employee pension
        benefit plan (as defined in Section 3(2) of ERISA (a "Pension Plan"))
        maintained or previously maintained by it, has incurred or is expected
        to incur any material liability to the Pension Benefit Guaranty
        Corporation ("PBGC"), or to the Internal Revenue Service ("IRS") or to
        the Department of Labor with respect to any Pension Plan. There is not
        currently pending with the PBGC any filing with respect to any
        reportable event under Section 4043 of ERISA nor has any reportable
        event occurred as to which a filing is required and has not been made.
 
             (3) Full payment has been made (or proper accruals have been
        established) for all contributions which are required or for which
        benefits have accrued, for periods prior to the Closing Date, as defined
        in Section 6.1 hereof, under the terms of each Employee Plan, ERISA, or
        a collective bargaining agreement, no accumulated funding deficiency (as
        defined in Section 302 of ERISA or Section 412 of the Code) whether or
        not waived, exists with respect to any Pension Plan (including any
        Pension Plan previously maintained by Citizens or Citizens Bank), and
        except as set forth on Schedule F, there is no "unfunded current
        liability" (as defined in Section 412 of the Code) with respect to any
        Pension Plan.
 
             (4) No Employee Plan is a "multiemployer plan" (as defined in
        Section 3(37) of ERISA). Neither Citizens nor Citizens Bank has incurred
        any liability under Section 4201 of ERISA for a complete or partial
        withdrawal from a
 
                                      I-12
 
<PAGE>
        multi-employer plan (as defined in Section 3(37) of ERISA). Neither
        Citizens nor Citizens Bank has participated in or agreed to participate
        in, a multiemployer plan (as defined in Section 3(37) of ERISA).
 
             (5) All Employee Plans that are "employee benefit plans," as
        defined in Section 3(3) of ERISA, that are maintained by Citizens or
        Citizens Bank or previously maintained by Citizens or Citizens Bank
        comply and have been administered in compliance in all material respects
        with ERISA and all other applicable legal requirements, including the
        terms of such plans, collective bargaining agreements, annual reporting
        requirements of the IRS and the Department of Labor, and securities
        laws. Neither Citizens nor Citizens Bank has any material liability
        under any such plan that is not reflected in the Citizens Financial
        Statements or on Schedule F hereto.
 
             (6) Except as set forth on Schedule F, no prohibited transaction
        has occurred with respect to any Employee Plan that is an "employee
        benefit plan" (as defined in Section 3(3) of ERISA) maintained by
        Citizens or Citizens Bank or previously maintained by Citizens or
        Citizens Bank that would result, directly or indirectly, in material
        liability under ERISA or in the imposition of a material excise tax
        under Section 4975 of the Code.
 
             (7) Schedule F identifies each Employee Plan that is an "employee
        welfare benefit plan" (as defined in Section 3(1) of ERISA) and which is
        funded. The funding under each such plan does not exceed the limitations
        under Section 419A(b) or 419A(c) of the Code. Neither Citizens nor
        Citizens Bank is subject to taxation on the income of any such plan or
        any such plan previously maintained by Citizens or Citizens Bank.
 
             (8) Schedule F identifies the method of funding (including any
        individual accounting) for all post-retirement medical or life insurance
        benefits for the employees of Citizens and Citizens Bank. Schedule F
        also discloses the funded status of these Employee Plans.
 
             (9) Schedule F identifies each corporate owned life insurance
        policy, including any key man insurance policy and policy insuring the
        life of any current or former director or employee of Citizens or
        Citizens Bank, and indicates for each such policy, the face amount of
        coverage, cash surrender value, if any, and annual premiums.
 
             (10) No trade or business is, or has ever been, treated as a single
        employer with Citizens or Citizens Bank for employee benefit purposes
        under ERISA and the Code, other than a subsidiary identified on Schedule
        M.
 
          (n) INSURANCE. All policies or binders of fire, liability, product
     liability, workmen's compensation, vehicular and other insurance held by or
     on behalf of Citizens or Citizens Bank are described on Schedule J and are
     valid and enforceable in accordance with their terms, are in full force and
     effect, and insure against risks and liabilities to the extent and in the
     manner customary for the industry and are deemed appropriate and sufficient
     by Citizens and Citizens Bank. Neither Citizens nor Citizens Bank is in
     default with respect to any provision contained in any such policy or
     binder and has not failed to give any notice or present any claim under any
     such policy or binder in due and timely fashion. Neither Citizens nor
     Citizens Bank has received notice of cancellation or non-renewal of any
     such policy or binder. Neither Citizens nor Citizens Bank has knowledge of
     any inaccuracy in any application for such policies or binders, any failure
     to pay premiums when due or any similar state of facts that might form the
     basis for termination of any such insurance. Neither Citizens nor Citizens
     Bank has knowledge of any state of facts or of the occurrence of any event
     that is reasonably likely to form the basis for any material claim against
     it not fully covered (except to the extent of any applicable deductible) by
     the policies or binders referred to above. Neither Citizens nor Citizens
     Bank has received notice from any of its insurance carriers that any
     insurance premiums will be materially increased in the future or that any
     such insurance coverage will not be available in the future on
     substantially the same terms as now in effect.
 
          (o) LOAN PORTFOLIO. Each loan outstanding on the books of Citizens and
     Citizens Bank is in all respects what it purports to be, was made in the
     ordinary course of business, was not known to be uncollectible at the time
     it was made, accrues interest (except for loans recorded on Citizens Bank's
     books as non-accrual) in accordance with the terms of the loan, and with
     respect to loans originated by Citizens Bank was made in accordance with
     Citizens Bank's standard loan policies as in effect at the time the loan
     was negotiated except for loans to facilitate the sale of OREO or loans
     with renegotiated terms and conditions. The records of Citizens Bank
     regarding all loans outstanding and OREO owned by Citizens Bank are
     accurate in all material respects, and the risk classifications for loans
     outstanding are, in the best judgment of the management of Citizens,
     appropriate. The allowance for loan losses, as reflected in the Citizens
     Financial Statements, has been established in accordance with generally
     accepted accounting principles. In the best judgment of the management of
     Citizens, such reserves are adequate as of the date hereof and will be
     adequate as of the Effective Time of the Holding Company Merger to absorb
     all known and anticipated loan losses in the loan portfolio of Citizens
     Bank. Except as identified on Schedule K, no loan in excess of $500,000 has
     been classified by examiners (regulatory or internal) as "Special Mention",
     "Substandard", "Doubtful", "Loss", or words of similar import. Except as
     disclosed on
 
                                      I-13
 
<PAGE>
     Schedule G, the OREO included in any nonperforming asset of Citizens Bank
     is recorded at the lower of cost or fair value less estimated costs to sell
     based on independent appraisals that comply with the requirements of the
     Financial Institutions Reform, Recovery and Enforcement Act of 1989 and
     Uniform Standards of Professional Appraisal Practice. Except as identified
     on Schedule K, to the knowledge of the management of Citizens and Citizens
     Bank, each loan reflected as an asset on the Citizens Financial Statements
     is the legal, valid and binding obligation of the obligor and any
     guarantor, subject to bankruptcy, insolvency, fraudulent conveyance and
     other laws of general applicability relating to or affecting creditors'
     rights and to general principles of equity, and no defense, offset or
     counterclaim has been asserted with respect to any such loan, which if
     successful would have a material adverse effect on the financial condition,
     results of operation or business of Citizens on a consolidated basis.
 
          (p) ABSENCE OF CHANGES. Except as identified on Schedule L, since
     December 31, 1995, there has not been any material adverse change in the
     aggregate assets or liabilities, earnings or business of Citizens, other
     than changes resulting from or attributable to (i) changes since such date
     in laws or regulations, generally accepted accounting principles or
     interpretations of either thereof that affect the banking or savings and
     loan industries generally, (ii) changes since such date in the general
     level of interest rates, (iii) expenses since such date incurred in
     connection with the transactions contemplated by this Agreement, (iv)
     accruals and reserves by Citizens or Citizens Bank since such date pursuant
     to the terms of Section 4.8 hereof, or (v) any other accruals, reserves or
     expenses incurred by Citizens or Citizens Bank since such date and noted on
     Schedule L. Since December 31, 1995, the business of Citizens has been
     conducted only in the ordinary course.
 
          (q) BROKERS AND FINDERS. Neither Citizens, Citizens Bank nor any of
     their officers, directors or employees have employed any broker or finder
     or incurred any liability for any brokerage fees, commissions or finders'
     fees in connection with the transactions contemplated herein except for the
     engagement of Keefe, Bruyette & Woods, whose fee for its engagement shall
     not exceed approximately $700,000.
 
          (r) SUBSIDIARIES; PARTNERSHIPS AND JOINT VENTURES. Citizens' only
     subsidiaries, direct or indirect, other than Citizens Bank, are set forth
     in Schedule M. Such corporations are duly organized, validly existing and
     in good standing under the laws of their jurisdiction of incorporation and
     have all requisite corporate power and authority to own, lease and operate
     their properties and to carry on their business as now being conducted in
     all material respects. Citizens owns, directly or indirectly, all of the
     issued and outstanding common stock of its subsidiaries free and clear of
     any liens, claims, encumbrances, charges or rights of third parties of any
     kind whatsoever and is not a party to any joint venture agreement or
     partnership except as set forth in Schedule M.
 
          (s) REPORTS. Since January 1, 1992 Citizens and Citizens Bank (and any
     corporation merged into Citizens or Citizens Bank) have filed all material
     reports and statements, together with any amendments required to be made
     with respect thereto, that were required to be filed with (i) the FDIC,
     (ii) the Maryland Department, (iii) the Office of the Comptroller of the
     Currency ("OCC"), (iv) the Virginia Bureau of Financial Institutions (the
     "Virginia Bureau"), (v) the SEC and (vi) any other governmental or
     regulatory authority or agency having jurisdiction over their operations.
     Each of such reports and documents, including the financial statements,
     exhibits and schedules thereto, filed with the SEC pursuant to the 1934 Act
     was in form and substance in compliance in all material respects with the
     1934 Act. No such report or statement, or any amendments thereto, contains
     any statement which, at the time and in light of the circumstances under
     which it was made, was false or misleading with respect to any material
     fact necessary in order to make the statements contained therein not false
     or misleading. Citizens is a reporting company under Section 12(g) or 15(d)
     of the 1934 Act and the regulations of the SEC.

        the extent management of Citizens has actual knowledge of a violation of
        any Environmental Law with respect to any such property.
 
          Except as disclosed in Schedule N, to the best knowledge of Citizens
     and Citizens Bank,

             (i) Neither Citizens nor Citizens Bank is in violation of or liable
        under any Environmental Law;
 
             (ii) none of the Loan Portfolio Properties and Other Properties
        Owned is in violation of or liable under any Environmental Law; and

        investigations or proceedings pending or threatened relating to the
        liability of the Loan Portfolio Properties and Other Properties Owned
        under any Environmental Law, including without limitation any notices,
        demand letters or requests for information from any federal or state
        environmental agency relating to any such liabilities under or
        violations of Environmental Law.
 
          (u) ACCOUNTING; TAX; REGULATORY MATTERS. Subject to action taken by
     the Board of Directors of Citizens pursuant to or as a result of the
     exception clause to the first sentence of Section 4.4 hereof, Citizens has
     not taken or agreed to take any action or has any knowledge of any fact or
     circumstance that would prevent the Holding Company Merger from qualifying
     as a business combination accounted for as a pooling-of-interests, or
     prevent the Holding Company Combination (as defined in Section 5.1(e)) from
     qualifying as a reorganization within the meaning of Section 368 of the
     Code, or that would materially impede or delay receipt of any approval
     referred to in Section 4.6.
 
          (v) REGULATORY APPROVALS. Neither Citizens nor Citizens Bank knows of
     any reason why the approvals, consents and waivers of governmental
     authorities referred to in Sections 5.1(f) and 5.2(e) hereof should not be
     obtained on a timely basis without the imposition of any condition of the
     type referred to in Section 5.1(f) hereof.
 
          (w) CITIZENS STOCK BUYBACK PROGRAM. Citizens has terminated its stock
     buyback program announced on August 8, 1996, and has no plans to commence a

     supplement with respect thereto furnished prior to the date hereof, no
     written statement, certificate, schedule, list or other written information
     furnished by or on behalf of Citizens at any time to Crestar, in connection
     with this Agreement, when considered as a whole, contains or will contain
     any untrue statement of a material fact or omits or will omit to state a

     3.2. REPRESENTATIONS AND WARRANTIES OF CRESTAR, CRESTAR BANK AND
SUBSIDIARY. Crestar and Crestar Bank represent and warrant to Citizens and
Citizens Bank as follows:
 
          (a) ORGANIZATION, STANDING AND POWER. Crestar is a corporation duly
     organized, validly existing and in good standing under the laws of Virginia
     and has all requisite corporate power and authority to own, lease and
     operate its properties and to carry on its business as now being conducted.
     Crestar has delivered to Citizens complete and correct copies of its
     Articles of Incorporation and all amendments thereto to the date hereof and
     its By-laws as amended to the date hereof.
 
          Crestar Bank is a banking corporation duly organized, validly existing
     and in good standing under the laws of Virginia and has all requisite
     corporate power and authority to own, lease and operate its properties and
     to carry on its
 
                                      I-15

<PAGE>
     business as now being conducted. At the date of this Agreement, Crestar
     Bank has had no business operations. Crestar Bank has been formed to
     facilitate a conversion of Crestar Bank N.A. from a national banking
     association headquartered in the District of Columbia to a Virginia banking
     corporation, headquartered in Fairfax County, Virginia. After conversion of
     Crestar Bank N.A. into Crestar Bank, prior to the end of 1996 Crestar
     contemplates merging Crestar Bank (Virginia) and Crestar Bank MD into
     Crestar Bank DC. (Prior to that merger, Crestar Bank FSB will be merged
     into Crestar Bank MD.) It is anticipated that at the Effective Time of the
     Holding Company Merger, Crestar Bank will be the only banking subsidiary of
     Crestar and will carry on the business formerly conducted by Crestar Bank
     (Virginia), Crestar Bank N.A., Crestar Bank MD and Crestar Bank FSB.
 
          (b) CAPITAL STRUCTURE.
 
             (i) CRESTAR. The authorized capital stock of Crestar consists of
        100,000,000 shares of Common Stock, par value $5 and 2,000,000 shares of
        Preferred Stock, par value $100 of which 42,768,051 shares of Common
        Stock and no shares of Preferred Stock were issued and outstanding as of
        June 30, 1996. All of such issued and outstanding shares of Crestar
        Common Stock were validly issued, fully paid and nonassessable at such
        date.
 
             (ii) CRESTAR BANK. The authorized capital stock of Crestar Bank
        consists of 525,775 shares of common stock, $150 par value, of which no
        shares were issued and outstanding as of June 30, 1996. All shares of
        common stock of Crestar Bank, when issued, will be validly issued, fully
        paid and nonassessable. Once issued, Crestar will own all of the issued
        and outstanding capital stock of Crestar Bank free and clear of any
        liens, claims, encumbrances, charges or rights of third parties of any
        kind whatsoever.
 
             (iii) SUBSIDIARY. The authorized capital stock of Subsidiary
        consists of 1,000 shares of common stock, $5.00 par value, of which 100
        shares were issued and outstanding as of the date of this Agreement. All
        such issued and outstanding shares of common stock of Subsidiary were
        validly issued, fully paid and nonassessable. Crestar owns all of the
        issued and outstanding capital stock of Subsidiary free and clear of any
        liens, claims, encumbrances, charges or rights of third parties of any
        kind whatsoever. Subsidiary has been organized solely to facilitate the
        acquisition of Citizens, and since its organization on September 11,
        1996 has had no business operations, Subsidiary will have no business
        operations prior to the Effective Time of the Holding Company Merger.
 
          (c) AUTHORITY. The execution and delivery of this Agreement and the
     consummation of the transactions contemplated hereby have been duly and
     validly authorized by all necessary action on the part of Crestar; and this
     Agreement is a valid and binding obligation of Crestar, enforceable in

          (d) FINANCIAL STATEMENTS. Schedule O contains copies of the following
     consolidated financial statements of Crestar (the "Crestar Financial
     Statements"):
 
             (i) Consolidated Balance Sheets as of December 31, 1995 and 1994
        (audited) and as of June 30, 1996 and 1995 (unaudited);
 
             (ii) Consolidated Income Statements for each of the three years
        ended December 31, 1995, 1994, and 1993 (audited) and the six months
        ended June 30, 1996 and 1995 (unaudited);
 
             (iii) Consolidated Statements of Changes in Shareholders' Equity
        for each of the three years ended December 31, 1995, 1994 and 1993
        (audited) and the three and six months ended June 30, 1996 and 1995
        (unaudited); and
 
             (iv) Consolidated Statements of Cash Flows for each of the three
        years ended December 31, 1995, 1994 and 1993 (audited) and the six
        months ended June 30, 1996 and 1995 (unaudited).
 
     Such consolidated financial statements and the notes thereto have been
     prepared in accordance with generally accepted accounting principles
     applied on a consistent basis throughout the periods indicated unless
     otherwise noted in the Crestar Financial Statements. Each of such
     consolidated balance sheets, together with the notes thereto, presents
     fairly as of its date the financial condition and assets and liabilities of
     Crestar. The consolidated income statements, statements of changes in
     shareholders' equity and statements of cash flows, together with the notes
     thereto, present fairly the results of operations, shareholders' equity and
     cash flows of Crestar for the periods indicated in accordance with GAAP.
 
          (e) ABSENCE OF UNDISCLOSED LIABILITIES. At June 30, 1996 and December
     31, 1995, Crestar and its consolidated subsidiaries had no material
     obligations or liabilities, (contingent or otherwise) of any nature which
     were not reflected in the Crestar Financial Statement as of such dates, or
     disclosed in the notes thereto, except for those which are disclosed in
     Schedules specifically referred to herein or which in the aggregate are
     immaterial.
 
          (f) ABSENCE OF CHANGES. Since December 31, 1995 there has not been any
     material adverse change in the condition (financial or otherwise),
     aggregate assets or liabilities, earnings or business of Crestar, other
     than changes resulting from or attributable to (i) changes since such date
     in laws or regulations, generally accepted accounting principles or
     interpretations of either thereof that affect the banking or savings and
     loan industries generally, (ii) changes since such date in the general
     level of interest rates, and (iii) expenses since such date incurred in
     connection with the transactions contemplated by this Agreement. Since
     December 31, 1995 the business of Crestar has been conducted only in the
     ordinary course.
 
          (g) SUBSIDIARIES. Crestar's first-tier subsidiaries are Crestar Bank
     (a Virginia banking corporation separate and distinct from Crestar Bank
     DC), Crestar Bank N.A., Crestar Bank MD, Crestar Bank FSB, Crestar
     Insurance Agency, Inc., and Crestar Securities Corporation. Such
     corporations are duly organized, validly existing and in good standing
     under the laws of their respective jurisdictions of incorporation and have
     all requisite corporate power and authority to own, lease and operate their
     properties and to carry on their business as now being conducted in all
     material respects. As of the date hereof, Crestar, Crestar Bank and Crestar
     Securities Corporation (other than in a fiduciary capacity) do not own
     directly or indirectly, or have any rights to acquire, any shares of
     Citizens Common Stock.
 
          (h) REPORTS. Since January 1, 1992, Crestar has filed all material
     reports and statements, together with any amendments required to be made
     with respect thereto, that were required to be filed with (i) the Federal
     Reserve Board, (ii) the FDIC, (iii) the OCC, (iv) the Virginia Bureau, (v)
     the Office of Thrift Suspension ("OTS"), (vi) the Maryland Department,
     (vii) the SEC and (viii) any other governmental or regulatory authority or
     agency having jurisdiction over their operations. Each of such reports and
     documents, including the financial statements, exhibits and schedules
     thereto, filed with the SEC pursuant to the 1934 Act was in form and
     substance in compliance with the 1934 Act. No such report or statement, or
     any amendments thereto, contains any statement which, at the time and in
     light of the circumstances under which it was made, was false or misleading
     with respect to any material fact necessary in order to make the statements
     contained therein not false or misleading.
 
          (i) TAX MATTERS. Each of Crestar, Crestar Bank, and all other
     corporations that are members of the same "affiliated group," as defined in
     Section 1504(a)(1) of the Code, as Crestar (collectively, the "Crestar
     Group") has filed or caused to be filed or (in the case of returns or
     reports not yet due) will file all tax returns and reports required to have
     been filed by or for it before the Effective Time of the Holding Company
     Merger. Each member of the Crestar Group has paid or made adequate
     provision for or (with respect to returns or reports not yet filed) before
     the Effective Time of the Holding Company Merger will pay or make adequate
     provision for all taxes, additions to tax, penalties, and interest for all
 
                                      I-17
 
<PAGE>
     periods covered by those returns or reports. The consolidated balance
     sheets contained in the Crestar Financial Statements fully and properly
     reflect, as of the dates thereof, the aggregate liabilities of the members
     of the Crestar Group for all accrued taxes, additions to tax, penalties and
     interest in accordance with GAAP. For periods ending after December 31,
     1995, the books and records of each member of the Crestar Group fully and
     properly reflect its liability for all accrued taxes, additions to tax,
     penalties and interest in accordance with GAAP. Except as disclosed in
     Schedule P, no member of the Crestar Group has granted (nor is it subject
     to) any waiver of the period of limitations for the assessment of tax for
     any currently open taxable period, and no unpaid tax deficiency has been
     asserted in writing against or with respect to any member of the Crestar
     Group by any taxing authority.
 
          (j) PROPERTY. Crestar and its subsidiaries own (or enjoy use of under
     capital leases) all property reflected on the Crestar Financial Statements
     as of June 30, 1996 and December 31, 1995 as being owned by them (except
     property sold or otherwise disposed of in the ordinary course of business).
     All property shown as being owned is owned free and clear of mortgages,
     liens, pledges, charges or encumbrances of any nature whatsoever, except
     those referred to in such Crestar Financial Statements or the notes
     thereto, liens for current taxes not yet due and payable, any unfiled
     mechanic's liens and such encumbrances and imperfections of title, if any,
     as are not substantial in character or amount or otherwise would materially
     impair Crestar's consolidated business operations. The leases relating to
     leased property are fairly reflected in such Crestar Financial Statements.
 
          All property and assets material to the business or operations of
     Crestar and its subsidiaries are in substantially good operating condition
     and repair, and such property and assets are adequate for the business and
     operations of Crestar and its subsidiaries.
 
          (k) AGREEMENTS IN FORCE AND EFFECT. All material contracts,
     agreements, plans, leases, policies and licenses of Crestar and its
     subsidiaries are valid and in full force and effect; and Crestar and its
     subsidiaries have not breached any material provision of, or are in default
     in any material respect under the terms of, any such contract, agreement,
     lease, policy or license, the effect of which breach or default would have
     a material adverse effect upon the financial condition, results of
     operations or business of Crestar and its subsidiaries taken as a whole.
 
          (l) LEGAL PROCEEDINGS; COMPLIANCE WITH LAWS. There is no legal,
     administrative, arbitration or other proceeding or governmental
     investigation pending, or, to the knowledge of Crestar's management,
     threatened or probable of assertion which, if decided adversely, would have
     a material adverse effect on the financial condition, results of
     operations, business or prospects of Crestar on a consolidated basis.
     Crestar and its subsidiaries have complied with any laws, ordinances,
     requirements, regulations or orders applicable to their respective
     businesses, except where noncompliance would not have a material adverse
     effect on the financial condition, results of operations, business or
     prospects of Crestar on a consolidated basis. Crestar and its subsidiaries
     have all licenses, permits, orders or approvals of any federal, state,
     local or foreign governmental or regulatory body that are necessary for the
     conduct of the respective businesses of Crestar and its subsidiaries and
     the absence of which would have a material adverse effect on the financial
     condition, results of operations, business or prospects of Crestar on a
     consolidated basis; the Permits are in full force and effect; Crestar is
     not aware of any material violations that are or have been recorded in
     respect of any Permit nor has Crestar or its subsidiaries received notice
     of any violations; and no proceeding is pending or, to the knowledge of
     Crestar, threatened to revoke or limit any Permit. Neither Crestar nor its
     subsidiaries are subject to any judgment, order, writ, injunction or decree
     which materially adversely affects, or might reasonably be expected to
     materially adversely affect, the financial condition, results of
     operations, business or prospects of Crestar on a consolidated basis.
 
          (m) EMPLOYEE BENEFIT PLANS.
 
             (1) Neither Crestar nor any of its subsidiaries, nor any employee
        benefit pension plan (as defined in Section 3(2) of ERISA (a "Pension
        Plan")) maintained by it, has incurred any material liability to the
        PBGC or to the Internal Revenue Service with respect to any Pension
        Plan, deferred compensation, consultant, severance, thrift, option,
        bonus and group insurance contract or any other incentive, welfare and
        employee benefit plan and agreement presently in effect, or approved
        prior to the date hereof, for the benefit of employees or former
        employees of Crestar and its subsidiaries or the dependents or
        beneficiaries of any employee or former employee of Crestar or any
        subsidiary (the "Crestar Employee Plans"). There is not currently
        pending with the PBGC any filing with respect to any reportable event
        under Section 4043 of ERISA nor has any reportable event occurred as to
        which a filing is required and has not been made.
 
                                      I-18
 
<PAGE>
             (2) Full payment has been made (or proper accruals have been
        established) of all contributions which are required for periods prior
        to the Closing Date under the terms of each Crestar Employee Plan,
        ERISA, or a collective bargaining agreement, and no accumulated funding
        deficiency (as defined in Section 302 of ERISA or Section 412 of the
        Code) whether or not waived, exists with respect to any Pension Plan.
 
             (3) No Crestar Employee Plan is a "multiemployer plan" (as defined
        in Section 3(37) of ERISA). Neither Crestar nor Crestar Bank has
        incurred any material liability under Section 4201 of ERISA for a
        complete or partial withdrawal from a multiemployer plan (as defined in
        Section 3(37) of ERISA). Neither Crestar nor Crestar Bank has
        participated in or agreed to participate in, a multiemployer plan (as
        defined in Section 3(37) of ERISA).
 
             (4) All "employee benefit plans," as defined in Section 3(3) of
        ERISA, that are maintained by Crestar comply and have been administered
        in compliance in all material respects with ERISA and all other
        applicable legal requirements, including the terms of such plans,
        collective bargaining agreements and securities laws. Neither Crestar
        nor Crestar Bank has any material liability under any such plan that is
        not reflected in the Crestar Financial Statements.
 
             (5) No prohibited transaction has occurred with respect to any
        "employee benefit plan" (as defined in Section 3(3) of ERISA) maintained
        by Crestar or Crestar Bank that would result, directly or indirectly, in
        material liability under ERISA or in the imposition of a material excise
        tax under Section 4975 of the Code.
 
          (n) REGULATORY APPROVALS. Crestar knows of no reason why the
     approvals, consents and waivers of governmental authorities referred to in
     Sections 5.1(f) and 5.2(e) hereof should not be obtained on a timely basis
     without the imposition of any condition of the type referred to in Section
     5.1(f) hereof.
 
          (o) CRESTAR STOCK BUYBACK PROGRAM. Crestar has terminated its stock
     buyback program announced July 11, 1996 and has no plans to commence a
     stock buyback program.
 
          (p) DISCLOSURE. Except to the extent of any subsequent correction or
     supplement with respect thereto furnished prior to the date hereof, no
     written statement, certificate, schedule, list or other written information
     furnished by or on behalf of Crestar at any time to Citizens, in connection
     with this Agreement when considered as a whole, contains or will contain
     any untrue statement of a material fact or omits or will omit to state a
     material fact necessary in order to make the statements herein or therein,
     in light of the circumstances under which they were made, not misleading.
     Each document delivered or to be delivered by Crestar to Citizens is or
     will be a true and complete copy of such document, unmodified except by
     another document delivered by Crestar.
 
                                   ARTICLE IV
                       CONDUCT AND TRANSACTIONS PRIOR TO
                          EFFECTIVE TIME OF THE MERGER
 
     4.1. ACCESS TO RECORDS AND PROPERTIES OF CRESTAR, CRESTAR BANK, CITIZENS
AND CITIZENS BANK; CONFIDENTIALITY. Between the date of this Agreement and the
Effective Time of the Holding Company Merger, Crestar on the one hand, and each
of Citizens and Citizens Bank on the other, agree to give to the other
reasonable access to all the premises and books and records (including tax
returns filed and those in preparation) of it and its subsidiaries and to cause
its officers to furnish the other with such financial and operating data and
other information with respect to the business and properties as the other shall
from time to time request for the purposes of verifying the representations and
warranties set forth herein, preparing the Registration Statement (as defined in
Section 4.2) and applicable regulatory filings (as set forth in Section 4.6),
and preparing unaudited financial statements of Citizens as of a date prior to
the Effective Time of the Holding Company Merger in order to facilitate
Crestar's performance of its post-Closing Date financial reporting requirements,
provided, however, that any such investigation shall be conducted in such manner
as not to interfere unreasonably with the operation of the respective business
of the other. Crestar and Citizens shall each maintain the confidentiality of
all confidential information furnished to it by the other party hereto
concerning the business, operations, and financial condition of the party
furnishing such information, and shall not use any such information except in
furtherance of the Holding Company Merger. If this Agreement is terminated, each
party hereto shall promptly return all documents and copies of, and all
workpapers containing, confidential information received from the other party
hereto. The obligations of confidentiality under this Section 4.1 shall survive
any such termination of this Agreement and shall remain in effect, except to the
extent that (a) one party shall have directly or indirectly acquired the assets
and business of the other party; (b) as to any particular confidential
information with respect to one party, such information (i) shall become

     4.2. REGISTRATION STATEMENT, PROXY STATEMENT, SHAREHOLDER APPROVAL.
Citizens and Crestar will duly call and will hold meetings of their respective
shareholders for the purpose of approving, in the case of Citizens, the Holding
Company Merger and, in the case of Crestar, the issuance of Crestar Common Stock
in the Holding Company Merger and will comply fully with the provisions of the
1933 Act and the 1934 Act and the rules and regulations of the SEC under such
acts to the extent applicable, and their respective Articles of Incorporation
and By-laws relating to the call and holding of meetings of shareholders for
such purpose. Subject, in the case of Citizens, to action taken by its Board of
Directors pursuant to or as a result of the exception clause to the first
sentence of Section 4.4 hereof, the boards of directors of Citizens and Crestar
will recommend to and actively encourage their respective shareholders that they
vote in favor of, in the case of Citizens, the Holding Company Merger and, in
the case of Crestar, the issuance of Crestar Common Stock in the Holding Company
Merger. If, in the case of Crestar, the fairness opinion received from Morgan
Stanley & Co. Incorporated on the date hereof, or in the case of Citizens, the
fairness opinion received from Keefe, Bruyette & Woods on the date hereof is
withdrawn, the board of directors of the party with respect to which such
fairness opinion has been withdrawn may, in its discretion, submit the matters
described in this Section 4.2 for shareholder approval without a recommendation
from the board of directors. Crestar and Citizens will jointly prepare the joint
proxy statement-prospectus to be used in connection with such meetings (the
"Proxy Statement-Prospectus") and Crestar will prepare and file with the SEC a
Registration Statement on Form S-4 (the "Registration Statement"), of which such
Proxy Statement- Prospectus shall be a part, and will use its best efforts
promptly to have the Registration Statement declared effective. In connection
with the foregoing, Crestar will comply with the requirements of the 1933 Act,
the 1934 Act, the rules and regulations of the SEC under such acts and the New
York Stock Exchange with respect to the offering and sale of Crestar Common
Stock in connection with the Holding Company Merger and with all applicable
state Blue Sky and securities laws. The notices of such meetings and the Proxy
Statement-Prospectus shall not be mailed to Crestar or Citizens shareholders
until the Registration Statement shall have become effective under the 1933 Act.
Citizens covenants that none of the information supplied by Citizens, and
Crestar covenants that none of the information supplied by Crestar, in the Proxy
Statement-Prospectus will, at the time of the mailing of the Proxy
Statement-Prospectus to Crestar and Citizens shareholders, contain any untrue
statement of a material fact nor will any such information omit any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances in which they were made, not misleading;
and at all times subsequent to the time of the mailing of the Proxy Statement-
Prospectus, up to and including the date of the meetings of Crestar and Citizens
shareholders to which the Proxy Statement-Prospectus relates, none of such
information in the Proxy Statement-Prospectus, as amended or supplemented, will
contain an untrue statement of a material fact or omit any material fact
required to be stated therein in order to make the statements therein, in light
of the circumstances in which they were made, not misleading.

     basis under this Agreement; and

     existing stock option or employee or director benefit plans in accordance

     Company Merger.
 
     4.4. NO SOLICITATION. Unless and until this Agreement shall have been
terminated pursuant to its terms, neither Citizens, Citizens Bank nor any of
their executive officers, directors, representatives, agents or affiliates
shall, directly or indirectly, encourage, solicit or initiate discussions or
negotiations (with any person other than Crestar) concerning any merger, sale of
substantial assets, tender offer, sale of shares of stock or similar transaction
involving Citizens or Citizens Bank or disclose, directly or indirectly, any
information not customarily disclosed to the public concerning Citizens or
Citizens Bank, afford to any other person access to the properties, books or
records of Citizens or Citizens Bank or otherwise assist any person preparing to
make or who has made such an offer, or enter into any agreement with any third
party providing for a business combination transaction, equity investment or
sale of significant amount of assets, except in a situation in which a majority
of the full Board of Directors of Citizens has determined in good faith, upon
advice of counsel, that such Board has a fiduciary duty to consider and respond
to a bona fide proposal by a third party (which proposal was not directly or
indirectly solicited by Citizens or Citizens Bank or any of their officers,
directors, representatives, agents or affiliates) and provides written notice of
its intention to consider such proposal and the material terms thereof to
Crestar at least five days before responding to the proposal. Citizens and
Citizens Bank will promptly communicate to Crestar the terms of any proposal
which it may receive in respect to any of the foregoing transactions.

shall comply with this Section 4.5) payable to Citizens shareholders of record
at the Effective Time of the Holding Company Merger.

     4.6. REGULATORY FILINGS; BEST EFFORTS. Crestar and Citizens shall jointly

receipt by Citizens and Citizens Bank of written confirmation from Crestar and
that there are no conditions to the obligations of Crestar under this Agreement
set forth in Article V which they believe will not be fulfilled so as to permit
them to consummate the Holding Company Merger and the other transactions
contemplated hereby, not earlier than three days prior to the Effective Time of
the Holding Company Merger Citizens shall establish such additional accruals,
reserves and charge-offs, through appropriate entries in its accounting books
and records, provided such adjustments are in accordance with GAAP and
applicable law and regulation as may be necessary to conform Citizens'
accounting and credit loss reserve practices and methods to those of Crestar
Bank (as such practices and methods are to be applied from and after the
Effective Time of the Holding Company Merger) and to Crestar Bank's plans with
respect to the conduct of the business of Citizens and Citizens Bank following
the Transaction, prior and the costs and expenses relating to the consummation
by Citizens and Citizens Bank of the Holding Company Merger and the other
transactions contemplated hereby. Any such accruals, reserves and charge-offs
shall not be deemed to cause any representation and warranty of Citizens and
Citizens Bank to be untrue or inaccurate as of the Effective Time of the Holding
Company Merger.

paragraph are established, Citizens and Citizens Bank will convey any OREO

consummation of the transactions contemplated by this Agreement.

     4.12. NYSE LISTING. Crestar will file with the New York Stock Exchange a

promptly after the occurrence of same and at the Closing Date by delivery of
updates of all Schedules, including future quarterly and annual Citizens and

shall be deemed to cure any breach of any representation or warranty made in
this Agreement or any Schedule unless Crestar or Citizens, as the case may be,
specifically agree thereto in writing, nor shall any such notification be
considered to constitute or give rise to a waiver by Citizens or Citizens Bank
on the one hand, or Crestar or Crestar Bank on the other hand, of any condition
set forth in this Agreement.
 
     4.14. TRANSACTIONS IN CRESTAR COMMON STOCK. Other than the issuance or
acquisition of Crestar Common Stock pursuant to Crestar employee benefit plans,

capacity in which it is directed to sell or purchase Crestar Common Stock, none

                   TERMINATION; SURVIVAL OF REPRESENTATIONS,
                 WARRANTIES AND COVENANTS; WAIVER AND AMENDMENT
 
     7.1. TERMINATION. This Agreement shall be terminated, and the Transaction
abandoned, if the shareholders of Crestar or Citizens shall not have given the
approval required by Section 4.2. Notwithstanding such approval by such
shareholders, this Agreement may be terminated at any time prior to the
Effective Time of the Holding Company Merger, by:
 
          (a) The mutual consent of Crestar and Citizens, as expressed by their
     respective Boards of Directors;
 
          (b) Either Crestar on the one hand or Citizens on the other hand, as
     expressed by their respective Boards of Directors, if the Holding Company
     Merger has not occurred by June 30, 1997, provided that the failure of the
     Holding Company Merger to so occur shall not be due to a willful breach of
     any representation, warranty, covenant or agreement by the party seeking to
     terminate this Agreement;
 
          (c) By Crestar in writing authorized by its Board of Directors if
     Citizens or Citizens Bank has, or by Citizens in writing authorized by its
     Board of Directors, if Crestar or Crestar Bank has, in any material
     respect, breached (i) any covenant or agreement contained herein, or (ii)
     any representation or warranty contained herein, in any case if such breach
     has not been cured by the earlier of 30 days after the date on which
     written notice of such breach is given to the party committing such breach
     or the Closing Date; provided that it is understood and agreed that either
     party may terminate this Agreement on the basis of any such material breach
     of any representation or warranty which is not cured within 30 days of
     written notice thereof contained herein notwithstanding any qualification
     therein relating to the knowledge of the other party;
 
          (d) Either Crestar on the one hand or Citizens on the other hand, as
     expressed by their respective Boards of Directors, in the event that any of
     the conditions precedent to the obligations of such parties to consummate
     the Holding Company Merger have not been satisfied or fulfilled or waived
     by the party entitled to so waive on or before the Closing Date, provided
     that no party shall be entitled to terminate this Agreement pursuant to
     this subparagraph (d) if the condition precedent or conditions precedent
     which provide the basis for termination can reasonably be and are satisfied
     within a reasonable period of time, in which case, the Closing Date shall
     be appropriately postponed;
 
          (e) Citizens, if the Board of Directors of Citizens shall have
     determined in its sole discretion, exercised in good faith, that the
     Holding Company Merger has become inadvisable or impracticable by reason of
     (A) the institution of any litigation, proceeding or investigation
     (including under federal antitrust laws) to restrain or prohibit the
     consummation of the Transaction or to obtain other relief in connection
     with this Agreement, or (B) commencement of a competing offer for Citizens
     Common Stock which is significantly better than Crestar's offer, and which
     Crestar has certified to Citizens, in writing, it is unwilling to meet;
 
          (f) Crestar, if the Board of Directors of Crestar shall have
     determined in its sole discretion, exercised in good faith, that the
     Holding Company Merger, has become inadvisable or impracticable by reason
     of (A) the institution of any litigation, proceeding or investigation
     (including under federal antitrust laws) to restrain or prohibit the
     consummation of the Transaction or to obtain other relief in connection
     with this Agreement or (B) public commencement of a competing offer for
     Citizens Common Stock which is significantly better than Crestar's offer,
     and which Crestar certifies to Citizens, in writing, it is unwilling to
     meet;
 
          (g) Crestar or Citizens, if the Federal Reserve Board, the Maryland
     Department, the FDIC or the Virginia Bureau deny approval of the
     Transaction and the time period for all appeals or requests for
     reconsideration has run;
 
          (h) Citizens, by action of its Board of Directors, at any time during
     the five-day period prior to the fifth day prior to the Closing Date, if
     the Average Closing Price as defined below of Crestar Common Stock shall be
     $48.00 or less, provided, however, that during the five-day period
     following the provision by Citizens of written notice of termination to
     Crestar pursuant to this Section 7.1(h) Crestar shall have the option of
     postponing the Closing Date for 15 trading days, during the first 10
     trading days of which a new Average Closing Price of Crestar Common Stock
     shall be determined based on the closing sales price of Crestar Common
     Stock as reported on the consolidated tape on the New York Stock Exchange
     for each of such 10 trading days (the "Adjusted Average Closing Price"). If
     the Adjusted Average Closing Price is more than $48.00, no termination
     shall be deemed to have occurred pursuant to this Section 7.1(h) and this
     Agreement shall remain in full force and effect in accordance with its
     terms. If the Adjusted Average Closing Price is $48.00 or less, Crestar
     shall have the option of increasing the consideration to be received by
     holders of Citizens Common Stock hereunder by adjusting the Exchange Ratio
     to equal a number equal to the quotient obtained by dividing
 
                                      I-26
 
<PAGE>
     $40.08 by the Adjusted Average Closing Price, in which case Crestar shall
     give prompt written notice to Citizens of such election and the revised
     Exchange Ratio and no termination shall be deemed to have occurred pursuant
     to this Section 7.1(h) and this Agreement shall remain in full force and
     effect in accordance with its terms (except as the Exchange Ratio shall
     have been so modified and any references herein to "Exchange Ratio" shall
     thereafter be deemed to refer to the Exchange Ratio as adjusted pursuant to
     this Section 7.1(h)). In no event shall the modified Exchange Ratio be less
     than 0.835 shares of Crestar Common Stock for each share of Citizens Common
     Stock.
 
          For purposes of this Section 7.1(h), the "Average Closing Price" shall
     be the average of the closing sales price of Crestar Common Stock as
     reported on the consolidated tape on the New York Stock Exchange for each
     of the 10 trading days ending on the 10th day prior to the Closing Date
     established pursuant to Section 6.1 of this Agreement.
 
     7.2. EFFECT OF TERMINATION. In the event of the termination and abandonment
of this Agreement and the Holding Company Merger pursuant to Section 7.1, this
Agreement, other than the provisions of Sections 4.1 (last three sentences) and
9.1, shall become void and have no effect, without any liability on the part of
any party or its directors, officers or shareholders, provided that nothing
contained in this Section 7.2 shall relieve any party from liability for any
willful breach of this Agreement.
 
     7.3. SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS. The respective
representations and warranties, obligations, covenants and agreements (except
for those contained in Sections 1.2, 1.3, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 4.1
(last three sentences), 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8 and 9.1, which
shall survive the effectiveness of the Holding Company Merger) of Crestar,
Crestar Bank, Citizens and Citizens Bank contained herein shall expire with, and
be terminated and extinguished by, the effectiveness of the Holding Company and
shall not survive the Effective Time of the Holding Company Merger.
 
     7.4. WAIVER AND AMENDMENT. Any term or provision of this Agreement may be
waived in writing at any time by the party which is, or whose shareholders are,
entitled to the benefits thereof and this Agreement may be amended or
supplemented by written instructions duly executed by all parties hereto at any
time, whether before or after the meeting of Crestar's or Citizens' shareholders
referred to in Section 4.2 hereof, excepting statutory requirements and
requisite approvals of shareholders and regulatory authorities, provided that
any such amendment or waiver executed after shareholders of Crestar or Citizens
have approved this Agreement and the Holding Company Plan of Merger shall not
modify either the amount or form of the consideration to be received by such
Citizens shareholders for their shares of Citizens Common Stock or otherwise
materially adversely affect such shareholders without their approval.
 
                                  ARTICLE VIII
                              ADDITIONAL COVENANTS
 
     8.1. INDEMNIFICATION OF CITIZENS OFFICERS AND DIRECTORS; LIABILITY
INSURANCE. After the Effective Time of the Holding Company Merger, Crestar
acknowledges its obligation to provide, and agrees to provide, indemnification
to the directors, employees and officers of Citizens and Citizens Bank and the
subsidiaries thereof for events occurring prior to or subsequent to the
Effective Time of the Holding Company Merger as if they had been directors,
employees or officers of Crestar prior to the Effective Time of the Holding
Company Merger, to the extent permitted under the Virginia State Corporation Act
and the Articles of Incorporation and Bylaws of Crestar as in effect as of the
date of this Agreement. Such indemnification shall continue for six years after
the Effective Time of the Holding Company Merger, provided that any right to
indemnification in respect of any claim asserted or made within such six year
period shall continue until final disposition of such claim. Crestar will
provide officers and directors liability insurance coverage to all Citizens and
Citizens Bank and subsidiaries thereof directors and officers, whether or not
they become part of the Crestar organization after the Effective Time of the
Holding Company Merger, to the same extent it is provided to Crestar's officers
and directors, provided that coverage will not extend to acts as to which a
claim has been made prior to the Effective Time of the Holding Company Merger.
The right to indemnification and insurance provided in this Section 8.1 is
intended to be for the benefit of directors, employees and officers of Citizens
and Citizens Bank and the subsidiaries thereof and as such may be personally
enforced by them at law or in equity.
 
     8.2. EMPLOYEE MATTERS. Employment and Severance Agreements. Crestar will
honor the terms of the employment and severance agreements with Jeffrey R.
Springer, Richard C. Bandiere, Raymond L. Gazelle, Jr. and Gary N. Geisel
described on Schedule F.
 
                                      I-27
 
<PAGE>
     8.3. EMPLOYEE BENEFIT MATTERS.
 
          (a) TRANSFERRED EMPLOYEES. All employees of Citizens or Citizens Bank
     (including subsidiaries) immediately prior to the Effective Time of the
     Merger who are employed by Crestar, Crestar Bank or another Crestar
     subsidiary immediately following the Effective Time of the Merger
     ("Transferred Employees") will be covered by Crestar's employee benefit
     plans as to which they are eligible based on their length of service,
     compensation, location, job classification, and position, including, where
     applicable, any incentive compensation plan. Notwithstanding the foregoing,
     Crestar may determine to continue any of the Citizens or Citizens Bank
     benefit plans for Transferred Employees in lieu of offering participation
     in Crestar's benefit plans providing similar benefits (e.g., medical and
     hospitalization benefits), to terminate any of the Citizens or Citizens
     Bank benefit plans, or to merge any such benefit plans with Crestar's
     benefit plans. Except as specifically provided in this Section 8.3 and as
     otherwise prohibited by law, Transferred Employees' service with Citizens
     or Citizens Bank which is recognized by the applicable benefit plan of
     Citizens or Citizens Bank at the Effective Time of the Holding Company
     Merger shall be recognized as service with Crestar for purposes of
     eligibility to participate and vesting, if applicable (but not for purposes
     of benefit accrual) under the corresponding Crestar benefit plan, if any,
     subject to applicable break-in-service rules.
 
          (b) HEALTH PLANS. Crestar agrees that any pre-existing condition,
     limitation or exclusion in its health plans shall not apply to Transferred
     Employees or their covered dependents who are covered under a medical or
     hospitalization indemnity plan maintained by Citizens or Citizens Bank on
     the date of the Holding Company Merger and who then change that coverage to
     Crestar's medical or hospitalization indemnity health plan at the time such
     Transferred Employees are first given the option to enroll in Crestar's
     health plans.
 
          (c) CITIZENS 401(K) PLAN. Crestar agrees that immediately following
     the Merger, all participants who then have accounts in the 401(k) plan
     maintained by Citizens or Citizens Bank (the "401(k) Plan") shall be fully
     vested in their account balances. Crestar, at its election, may continue
     the 401(k) Plan for the benefit of Transferred Employees (as such plan may
     be amended as of the Effective Time of the Holding Company Merger to
     provide current contributions and eligibility provisions identical to those
     under the Crestar Employees' Thrift and Profit Sharing Plan (the "Thrift
     Plan")), may merge the 401(k) Plan into the Thrift Plan or any other
     defined contribution plan maintained by Crestar, or may cease additional
     benefit accruals under and contributions to the 401(k) Plan and continue to
     hold the assets of such Plan until they are distributable in accordance
     with its terms. In the event of a merger of the 401(k) Plan into the Thrift
     Plan or a cessation of accruals and contributions under the 401(k) Plan,
     the Thrift Plan will recognize for purposes of eligibility to participate,
     early retirement, and eligibility for vesting, all Transferred Employees'
     service which is recognized under the 401(k) Plan, subject to applicable
     break-in-service rules.

          (d) CRESTAR RETIREMENT PLAN. The Retirement Plan for Employees of
     Crestar Financial Corporation and Affiliated Corporations ("Crestar's
     Retirement Plan") will recognize for purposes of eligibility to
     participate, vesting and eligibility for early retirement, but not for
     benefit accrual purposes, all Transferred Employees' service which is
     recognized under the qualified employees' defined benefit pension plan of
     Citizens (the "Citizens Pension Plan"), subject to applicable break-
     in-service rules. Crestar, at its option, may continue the Citizens Pension
     Plan as a frozen plan or may terminate the Citizens Pension Plan and pay
     out or annuitize benefits, or may merge the Citizens Pension Plan into
     Crestar's Retirement Plan. If the Citizens Pension Plan is terminated or if
     benefit accruals are suspended, or if the Citizens Pension Plan is merged
     into Crestar's Retirement Plan, each Transferred Employee who becomes a
     participant in Crestar's Retirement Plan will begin to accrue benefits
     under Crestar's Retirement Plan on and after the date of such termination,
     suspension or merger in accordance with the terms of Crestar's Retirement
     Plan.
 
          (e) COOPERATION. Citizens and Citizens Bank agree to cooperate with
     Crestar in implementing any decision made by Crestar under this Section 8.3
     with respect to employee benefit plans and to provide to Crestar on or
     before the Effective Time of the Holding Company Merger a schedule of
     service credit for prospective Transferred Employees.
 
     8.4. CRESTAR BANK/GWR OR MARYLAND ADVISORY BOARD OF DIRECTORS. Crestar Bank
will offer five to eight members of the Citizens board of directors a position
on Crestar Bank's GWR or Maryland Advisory Board. Members who agree to serve on
the GWR Advisory Board will be paid on the usual terms and conditions that
Crestar Bank pays members of its GWR or Maryland advisory board, and will be
subject to other generally applied conditions, including age eligibility.
Crestar, Citizens and Citizens Bank will cooperate in identifying the members of
the GWR or Maryland Advisory Board.
 
     8.5. STOCK OPTIONS. Holders of outstanding Citizens Options shall (a)
exercise the Citizens Options for Citizens Common Stock prior to the Closing
Date (if such options are by their terms then exercisable) and convert such
Common Stock held as of the Effective Time of the Holding Company Merger into
Crestar Common Stock or (b) have the Citizens Options
 
                                      I-28
 
<PAGE>
converted into options to purchase Crestar Common Stock as set forth in Section
2.2(e) hereof. Citizens agrees not to amend any option agreement to extend the
36 month period following termination of employment during which Citizens
Options may be exercised, or, except with the consent of Crestar, to otherwise
amend the terms of any outstanding option agreement.
 
     8.6. CRESTAR BOARD OF DIRECTORS. Following the Effective Time of the
Holding Company Merger, Crestar agrees to increase the number of members of
Crestar's and Crestar Bank's Board of Directors by two and to appoint Alfred H.
Smith, Jr. and Jeffrey R. Springer to fill the resulting vacancies.
 
     8.7. FURTHER ACTION RESPECTING STRUCTURE. Immediately following the Holding
Company Merger, Crestar expects to merge Citizens into Crestar pursuant to
provisions of Maryland and Virginia law. Citizens' Board of Directors, which
shall be the board of directors of the Surviving Corporation until such merger
is made effective, agree to approve and adopt all plans of merger and to take
any other action necessary to accomplish the Citizens/Crestar merger.
 
     Crestar may merge Citizens Bank into Crestar Bank immediately following the
Holding Company Merger and the Crestar/ Citizens merger, or it may determine to
delay such merger depending on the outcome of certain federal bank regulatory
initiatives currently underway. The directors of Citizens Bank agree to adopt
any such plans of merger and to take any such further action as may be necessary
to accomplish the merger of Citizens Bank into Crestar Bank at such time as
Crestar elects to effect such merger.
 
     8.8. BRANCH CLOSING LAW. Citizens and Citizens Bank agree to cooperate with
Crestar in achieving compliance with the Federal Branch Closing Law.

                                 PLAN OF MERGER
                                       OF
                        CDM ACQUISITION SUBSIDIARY, INC.
                                      INTO
                                CITIZENS BANCORP
 
     SECTION 1. MERGER. CDM Acquisition Subsidiary, Inc., a Maryland corporation
("Subsidiary") wholly-owned by Crestar Financial Corporation; a Virginia
corporation ("Crestar") shall, upon the time that Articles of Merger are made
effective by the State Department of Assessments and Taxation of the State of
Maryland (the "Effective Time of the Holding Company Merger"), be merged (the
"Holding Company Merger") into Citizens Bancorp, a Maryland corporation
("Citizens"), which shall be the "Surviving Corporation".
 
     SECTION 2. CONVERSION OF STOCK. At the Effective Time of the Holding
Company Merger:
 
          (i) Each share of Subsidiary Common Stock outstanding immediately
     prior to the Effective Time of the Holding Company Merger shall continue
     unchanged as an outstanding share of Common Stock of the Surviving
     Corporation.
 
          (ii) Subject to Section 3, each share of Citizens Common Stock which
     is issued and outstanding immediately prior to the Effective Time of the
     Holding Company Merger (other than shares held of record by Crestar) and
     which, under the terms of Section 4, is to be converted into Crestar Common
     Stock, shall be converted into 0.835 shares of Crestar Common Stock.
 
          (iii) At the Effective Time of the Holding Company Merger, Citizens'
     transfer books shall be closed and no further transfer of Citizens Common
     Stock shall be permitted.
 
          (iv) Each outstanding option to acquire shares of Citizens Common
     Stock ("Citizens Options") which has not been exercised shall be converted
     into options to purchase Crestar Common Stock as set forth in the Agreement
     and Plan of Reorganization dated September 16, 1996 among Crestar Financial
     Corporation, Crestar Bank DC, Subsidiary, Citizens and Citizens Bank of
     Maryland (the "Agreement").
 
     SECTION 3. POSSIBLE ADJUSTMENT OF EXCHANGE RATIO. The Agreement may be
terminated by Citizens if its Board of Directors so determines at any time
during the five-day period prior to the fifth day prior to the Closing Date, if
the Average Closing Price (as defined in Section 7.1(h) of the Agreement) is
$48.00 or less; provided, however, that Crestar shall have the option of
increasing the consideration to be received by holders of Citizens Common Stock
by adjusting the Exchange Ratio to a number equal to the quotient obtained by
dividing $40.08 by the Adjusted Average Closing Price (as defined in the
Agreement) on the terms and conditions described in Section 7.1(h) of the
Agreement.
 
     SECTION 4. MANNER OF CONVERSION. The manner in which each outstanding share
of Citizens Common Stock shall be converted into Crestar Common Stock, as
specified in Section 2, after the Effective Time of the Holding Company Merger,
shall be as follows:
 
          (i) Each share of Citizens Common Stock, other than shares held of
     record by Crestar, shall be exchanged for shares of Crestar Common Stock at
     the exchange ratio described in Section 2(ii).
 
          (ii) No fractional shares of Crestar Common Stock shall be issued, but
     instead the value of fractional shares shall be paid in cash (subject to
     all applicable withholding taxes), for which purpose the Average Closing
     Price (as defined in the Agreement) shall be employed.
 
          (iii) Certificates for shares of Citizens Common Stock shall be
     submitted in exchange for Crestar Common Stock accompanied by a Letter of
     Transmittal (to be promptly furnished by Crestar Bank to Citizens'
     shareholders of record as of the Effective Time of the Holding Company
     Merger). Until so surrendered, each outstanding certificate which, prior to
     the Effective Time of the Holding Company Merger, represented Citizens
     Common Stock, shall be deemed to evidence only the right to receive shares
     of Crestar Common Stock at the exchange ratio described in Section 2(ii).
     Until such outstanding shares formerly representing Citizens Common Stock
     are so surrendered, no dividend payable to holders of record of Crestar
     Common Stock as of any date subsequent to the Effective Time of the Holding
     Company Merger shall be paid to the holder of such outstanding certificates
     in respect thereof. Upon such surrender, dividends accrued or declared on
     Crestar Common Stock shall be paid in accordance with Section 2.2 of the
     Agreement.

     SECTION 5. DISSENTING SHARES. Pursuant to Section 3-202 of the Maryland
General Corporation Law, shareholders of Citizens do not have dissenters' rights
in the Holding Company Merger.
 
     SECTION 6. ARTICLES OF INCORPORATION, BYLAWS AND DIRECTORS OF THE SURVIVING
CORPORATION. At the Effective Time of the Holding Company Merger, there shall be
no change caused by the Holding Company Merger in the Articles of Incorporation
(except any change caused by the filing of Articles of Merger relating to the
Holding Company Merger), By-laws, or Board of Directors of the Surviving
Corporation.
 
     SECTION 7. CONDITIONS TO MERGER. Consummation of the Holding Company Merger
is subject to the following conditions:

     the outstanding shares of Citizens Common Stock and Crestar Common Stock.
 
          (ii) The approval of the Holding Company Merger by the Board of
     Governors of the Federal Reserve System, the Maryland Department of Labor,
     Licensing and Regulation, and the State Corporation Commission of Virginia.
 
          (iii) The satisfaction of the conditions contained in the Agreement or
     the waiver of such conditions by the party for whose benefit they were
     imposed.

by Section 3-114 of the Maryland General Corporation Law.

                                                                        ANNEX II
 
                             STOCK OPTION AGREEMENT
 
     This STOCK OPTION AGREEMENT ("Option Agreement") dated as of September 15,
1996, between CITIZENS BANCORP ("Citizens"), a Maryland corporation, and CRESTAR
FINANCIAL CORPORATION ("Crestar"), a Virginia corporation, recites and provides:
 
     A. The Boards of Directors of Citizens and Crestar have approved an
Agreement and Plan of Reorganization dated as of September 16, 1996 (the "Merger
Agreement") providing for the merger (the "Merger") of Citizens with and into a
subsidiary of Crestar.
 
     B. As a condition to and as consideration for Crestar's entry into the
Merger Agreement and to induce such entry, Citizens has agreed to grant to
Crestar the option set forth herein to purchase authorized but unissued shares
of Citizens Common Stock.
 
     NOW, THEREFORE, the parties agree as follows:
 
     I. DEFINITIONS.
 
     Capitalized terms defined in the Merger Agreement and used herein shall
have the same meanings as in the Merger Agreement.
 
     II. GRANT OF OPTION.
 
     Subject to the terms and conditions set forth herein, Citizens hereby
grants to Crestar an option (the "Option") to purchase up to 3,012,000 shares of
Citizens Common Stock at an exercise price of $40.00 per share payable in cash
as provided in Section 4; provided, however, that in the event Citizens issues
or agrees to issue any shares of Citizens Common Stock (other than as permitted
under the Merger Agreement) at a price less than $40.00 per share (as adjusted
pursuant to Section 6), the exercise price shall be such lesser price.
 
     III. EXERCISE OF OPTION.
 
          (i) Unless Crestar shall have breached in any material respect any
     material covenant or representation contained in the Merger Agreement and
     such breach has not been cured, Crestar may exercise the Option, in whole
     or part, at any time or from time to time if a Purchase Event (as defined
     below) shall have occurred and be continuing; provided that to the extent
     the Option shall not have been exercised, it shall terminate and be of no
     further force and effect (i) on the Effective Date of the Merger, or (ii)
     upon termination of the Merger Agreement in accordance with the provisions
     thereof (other than a termination resulting from a willful breach by
     Citizens of any Specified Covenant or, following the occurrence of a
     Purchase Event, failure of Citizens's stockholders to approve the Merger
     Agreement by the vote required under applicable law or under Citizens's
     Charter), or (iii) 12 months after termination of the Merger Agreement due
     to a willful breach by Citizens of any Specified Covenant or, following the
     occurrence of a Purchase Event, failure of Citizens's stockholders to
     approve the Merger Agreement by the vote required under applicable law or
     under Citizens's Charter. Any exercise of the Option shall be subject to
     compliance with applicable provisions of law.
 
          (ii) As used herein, a "Purchase Event" shall mean any of the
     following events or transactions occurring after the date hereof:
 
              (i) Citizens or any banking subsidiary of Citizens (a "Bank"),
                  without having received Crestar's prior written consent, shall
                  have entered into an agreement with any person (x) to merge or
                  consolidate, or enter into any similar transaction, except as
                  contemplated in the Merger Agreement, (y) to purchase, lease
                  or otherwise acquire all or substantially all of the assets of
                  Citizens or a Bank, or (z) to purchase or otherwise acquire
                  (including by way of merger, consolidation, share exchange or
                  any similar transaction) securities representing 10% or more
                  of the voting power of Citizens or a Bank;
 
              (ii) any person (other than Citizens or a Bank in a fiduciary
                   capacity, or Crestar, Crestar Bank, Crestar Bank N.A. or
                   Crestar Bank MD in a fiduciary capacity) shall have acquired
                   beneficial ownership or the right to acquire beneficial
                   ownership of 15% or more of the outstanding shares of
                   Citizens Common Stock after the date hereof (the term
                   "beneficial ownership" for purposes of this Option Agreement
                   having the meaning assigned thereto in Section 13(d) of the
                   Securities Exchange Act of 1934 (the "Exchange Act") and the
                   regulations promulgated thereunder);
 
                                      II-1
 
<PAGE>
             (iii) any person shall have made a bona fide proposal to Citizens
                   by public announcement or written communication that is or
                   becomes the subject of public disclosure to acquire Citizens
                   or a Bank by merger, consolidation, purchase of all or
                   substantially all of its assets or any other similar
                   transaction, and following such bona fide proposal the
                   stockholders of Citizens vote not to adopt the Merger
                   Agreement; or
 
              (iv) Citizens shall have willfully breached any Specified Covenant
                   following a bona fide proposal to Citizens or a Bank to
                   acquire Citizens or a Bank by merger, consolidation, purchase
                   of all or substantially all of its assets or any other
                   similar transaction, which breach would entitle Crestar to
                   terminate the Merger Agreement (without regard to the cure
                   periods provided for therein) and such breach shall not have
                   been cured prior to the Notice Date (as defined below).
 
     If more than one of the transactions giving rise to a Purchase Event under
this Section 3(b) is undertaken or effected, then all such transactions shall
give rise only to one Purchase Event, which Purchase Event shall be deemed
continuing for all purposes hereunder until all such transactions are abandoned.
As used in this Option Agreement, "person" shall have the meanings specified in
Sections 3(a)(9) and 13(d)(3) of the Exchange Act.
 
             (iii) In the event Crestar wishes to exercise the Option, it shall
                   send to Citizens a written notice (the date of which being
                   herein referred to as the "Notice Date") specifying (i) the
                   total number of shares it will purchase pursuant to such
                   exercise, and (ii) a place and date not earlier than three
                   business days nor later than 60 business days after the
                   Notice Date for the closing of such purchase ("Closing
                   Date"); provided that if prior notification to or approval of
                   any federal or state regulatory agency is required in
                   connection with such purchase, Crestar shall promptly file
                   the required notice or application for approval and shall
                   expeditiously process the same and the period of time that
                   otherwise would run pursuant to this sentence shall run
                   instead from the date on which any required notification
                   period has expired or been terminated or such approval has
                   been obtained and any requisite waiting period shall have
                   passed.
 
              (iv) As used herein, "Specified Covenant" means any covenant
                   contained in Sections 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.8,
                   4.10, 4.11, 4.13, or 6.1 of the Merger Agreement.
 
     IV. PAYMENT AND DELIVERY OF CERTIFICATES.
 
              (i) At the closing referred to in Section 3, Crestar shall pay to
                  Citizens the aggregate purchase price for the shares of
                  Citizens Common Stock purchased pursuant to the exercise of
                  the Option in immediately available funds by a wire transfer
                  to a bank account designated by Citizens.
 
              (ii) At such closing, simultaneously with the delivery of funds as
                   provided in subsection (a), Citizens shall deliver to Crestar
                   a certificate or certificates representing the number of
                   shares of Citizens Common Stock purchased by Crestar, and
                   Crestar shall deliver to Citizens a letter agreeing that
                   Crestar will not offer to sell or otherwise dispose of such
                   shares in violation of applicable law or the provisions of
                   this Option Agreement.
 
             (iii) Certificates for Citizens Common Stock delivered at a closing
                   hereunder may be endorsed with a restrictive legend which
                   shall read substantially as follows:
 
     "The transfer of the shares represented by this certificate is subject to
certain provisions of a Stock Option Agreement between the registered holder
hereof and Citizens Bancorp and to resale restrictions arising under the
Securities Act of 1933, as amended, a copy of which agreement is on file at the
principal office of Citizens Bancorp. A copy of such agreement will be provided
to the holder hereof without charge upon receipt by Citizens Bancorp of a
written request."
 
     It is understood and agreed that the above legend shall be removed by
delivery of substitute certificate(s) without such legend if Crestar shall have
delivered to Citizens a copy of a letter from the staff of the Commission, or an
opinion of counsel, in form and substance satisfactory to Citizens, to the
effect that such legend is not required for purposes of the Securities Act of
1933, as amended.
 
     V. REPRESENTATIONS.
 
     Citizens represents, warrants and covenants to Crestar as follows:
 
              (i) Citizens shall at all times maintain sufficient authorized but
                  unissued shares of Citizens Common Stock so that the Option
                  may be exercised without authorization of additional shares of
                  Citizens Common Stock.
 
                                      II-2
 
<PAGE>
              (ii) The shares to be issued upon due exercise, in whole or in
                   part, of the Option, when paid for as provided herein, will
                   be duly authorized, validly issued, fully paid and
                   nonassessable.
 
     VI. ADJUSTMENT UPON CHANGES IN CAPITALIZATION.
 
     In the event of any change in Citizens Common Stock by reason of stock
dividends, split-ups, mergers, recapitalizations, combinations, exchanges of
shares or the like, the type and number of shares subject to the Option, and the
purchase price per share, as the case may be, shall be adjusted appropriately.
In the event that any additional shares of Citizens Common Stock are issued or
otherwise become outstanding after the date of this Option Agreement (other than
pursuant to this Option Agreement), the number of shares of Citizens Common
Stock subject to the Option shall be adjusted so that, after such issuance, it
equals 19.9% of the number of shares of Citizens Common Stock then issued and
outstanding without giving effect to any shares subject or issued pursuant to
the Option. Nothing contained in this Section 6 shall be deemed to authorize
Citizens to breach any provision of the Merger Agreement.
 
     VII. REGISTRATION RIGHTS.
 
     If requested by Crestar, Citizens shall as expeditiously as possible file a
registration statement on a form of general use under the Securities Act if
necessary in order to permit the sale or other disposition of the shares of
Citizens Common Stock that have been acquired upon exercise of the Option in
accordance with the intended method of sale or other disposition requested by
Crestar. Crestar shall provide all information reasonably requested by Citizens
for inclusion in any registration statement to be filed hereunder. Citizens will
use its best efforts to cause such registration statement first to become
effective and then to remain effective for such period not in excess of 270 days
from the day such registration statement first becomes effective as may be
reasonably necessary to effect such sales or other dispositions. The first
registration effected under this Section 7 shall be at Citizens's expense except
for underwriting commissions and the fees and disbursements of Crestar's counsel
attributable to the registration of such Citizens Common Stock. A second
registration may be requested hereunder at Crestar's expense. In no event shall
Citizens be required to effect more than two registrations hereunder. The filing
of any registration statement hereunder may be delayed for such period of time
as may reasonably be required to facilitate any public distribution by Citizens
of Citizens Common Stock. If requested by Crestar, in connection with any such
registration, Citizens will become a party to any underwriting agreement
relating to the sale of such shares, but only to the extent of obligating itself
in respect of representations, warranties, indemnities and other agreements
customarily included in such underwriting agreements. Upon receiving any request
from Crestar or assignee thereof under this Section 7, Citizens agrees to send a
copy thereof to Crestar and to any assignee thereof known to Citizens, in each
case by promptly mailing the same, postage prepaid, to the address of record of
the persons entitled to receive such copies.

     VIII. SEVERABILITY.
 
     If any term, provision, covenant or restriction contained in this Option
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Option
Agreement shall remain in full force and effect, and shall in no way be
affected, impaired or invalidated. If for any reason such court or regulatory
agency determines that the Option will not permit the holder to acquire the full
number of shares of Citizens Common Stock provided in Section 2 (as adjusted
pursuant to Section 6), it is the express intention of Citizens to allow the
holder to acquire such lesser number of shares as may be permissible, without
any amendment or modification hereof.
 
     IX. MISCELLANEOUS.
 
          (i) EXPENSES. Except as otherwise provided herein, each of the parties
     hereto shall bear and pay all costs and expenses incurred by it or on its
     behalf in connection with the transactions contemplated hereunder,
     including fees and expenses of its own financial consultants, investment
     bankers, accountants and counsel.

          (ii) ENTIRE AGREEMENT. Except as otherwise expressly provided herein,
     this Option Agreement contains the entire agreement between the parties
     with respect to the transactions contemplated hereunder and supersedes all
     prior arrangements or understandings with respect thereto, written or oral.
     The terms and conditions of this Option Agreement shall inure to the
     benefit of and be binding upon the parties hereto and their respective
     successors and assigns. Nothing in this Option Agreement, expressed or
     implied, is intended to confer upon any party, other than the parties
     hereto, and their respective successors and assigns, any rights, remedies,
     obligations or liabilities under or by reason of this Option Agreement,
     except as expressly provided herein.
 
          (iii) ASSIGNMENT. Neither of the parties hereto may assign any of its
     rights or obligations under this Option Agreement or the Option created
     hereunder to any other person, without the express written consent of the
     other party, except
 
                                      II-3
 
<PAGE>
     that in the event a Purchase Event shall have occurred and be continuing
     Crestar may assign in whole or in part its rights and obligations

Board of Directors
Crestar Financial Corporation
919 East Main Street
Richmond, VA 23261
 
Members of the Board:
 
     We understand that Crestar Financial Corporation ("Crestar"), CDM
Acquisition Subsidiary, Inc. (the "Merger Sub"), Crestar Bank DC, each a wholly
owned subsidiary of Crestar, Citizens Bancorp ("Citizens") and Citizens Bank of
Maryland, a wholly owned subsidiary of Citizens, have entered into an Agreement
and Plan of Reorganization, dated as of September 15, 1996 (the "Merger
Agreement"), which provides, among other things, for the merger of the Merger
Sub with and into Citizens (the "Merger"). Pursuant to the Merger, each issued
and outstanding share of common stock, par value $2.50 per share, of Citizens
(the "Citizens Common Stock"), other than shares held in treasury or held by
Crestar or any wholly owned subsidiary of Crestar or Citizens, will be converted
into the right to receive 0.835 shares (the "Exchange Ratio") of common stock,
par value $5.00 per share, of Crestar (the "Crestar Common Stock"). The terms
and conditions of the Merger are more fully set forth in the Merger Agreement.
 
     You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Merger Agreement is fair from a financial point of view to Crestar.
 
     For purposes of the opinion set forth herein, we have:
 
        (i) analyzed certain publicly available financial statements and other
            information of Citizens and Crestar, respectively;
 
       (ii) analyzed certain internal financial statements and other financial
            and operating data concerning Citizens and Crestar prepared by the
            managements of Citizens and Crestar, respectively;
 
       (iii) analyzed certain financial projections of Citizens and Crestar
             prepared by the managements of Citizens and Crestar, respectively;
 
       (iv) discussed the past and current operations and financial condition
            and the prospects of Citizens and Crestar with senior executives of
            Citizens and Crestar, respectively;
 
       (v) analyzed the pro forma impact of the Merger on Crestar's earnings per
           share, consolidated capitalization and financial ratios;
 
       (vi) reviewed the reported prices and trading activity for the Citizens
            Common Stock and the Crestar Common Stock;
 
      (vii) compared the financial performance of Citizens and Crestar and the
            prices and trading activity of the Citizens Common Stock and the
            Crestar Common Stock with that of certain other comparable
            publicly-traded companies and their securities;
 
      (viii) discussed with independent auditors of Citizens their review of the
             financial and accounting affairs of Citizens and with the
             independent auditors of Crestar their review of the financial and
             accounting affairs of Crestar;
 
       (ix) discussed the results of regulatory examinations of Citizens and
            Crestar with the senior managements of the respective companies;
 
       (x) discussed the strategic objectives of the Merger and the plan for the
           combined company with senior executives of Citizens and Crestar;
 
                                     III-1
 
<PAGE>
      (xi) reviewed and discussed with senior managements of Citizens and
           Crestar certain estimates of the cost savings and revenue
           enhancements projected by Citizens and Crestar for the combined
           company and compared such amounts to those estimated in certain
           precedent transactions;
 
      (xii) reviewed the financial terms, to the extent publicly available, of
            certain comparable precedent transactions;

     (xiii) participated in discussions and negotiations among representatives
            of Citizens and Crestar and their financial and legal advisors;
 
      (xiv) reviewed the Merger Agreement and certain related documents;
 
      (xv) considered such other factors as we have deemed appropriate.
 
     We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, including the estimates
of cost savings and revenue enhancements expected to result from the Merger, we
have assumed that they have been reasonably prepared on bases reflecting the
best currently available estimates and judgments of the future financial
performance of Citizens and Crestar. We have not made any independent valuation
or appraisal of the assets or liabilities of Citizens and Crestar, nor have we
been furnished with any such appraisals and we have not examined any individual
loan credit files of Citizens or Crestar. In addition, we have assumed the
Merger will be consummated in accordance with the terms set forth in the Merger
Agreement. Our opinion is necessarily based on economic, market and other
conditions as in effect on, and the information made available to us as of, the
date hereof.

     We have acted as financial advisor to the Board of Directors of Crestar in
connection with this transaction and will receive a fee for our services. In the
past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services for Crestar and have received fees for
the rendering of these services.
 
     It is understood that this letter is for the information of the Board of
Directors of Crestar and may not be used for any other purpose without our prior
written consent, except that this opinion may be included in its entirety in any
filing with the Securities and Exchange Commission in connection with the
Merger. In addition, we express no opinion or recommendation as to how the
holders of Crestar Common Stock should vote at the stockholders' meeting held in
connection with the Merger.
 
     Based on the foregoing, we are of the opinion on the date hereof that the
Exchange Ratio pursuant to the Merger Agreement is fair from a financial point
of view to Crestar.
 
                                         Very truly yours,

Members of the Board:
 
     You have requested our opinion as investment bankers as to the fairness,
from a financial point of view, to the shareholders of Citizens Bancorp
("Citizens") of the exchange ratio in the proposed merger (the "Merger of
Citizens with and into Crestar Financial Corporation ("Crestar "), pursuant to
the Agreement and Plan of Merger dated as of September 15, 1996 between Citizens
and Crestar (the "Agreement "). Under the terms of the Merger, each outstanding
share of common stock of Citizens will be exchanged for .835 shares of common
stock of Crestar (the "Exchange Ratio "). It is our understanding that the
Merger will be accounted for as a pooling-of-interests under generally accepted
accounting principles.
 
     Keefe, Bruyette & Woods, Inc. as part of its investment banking business is
continually engaged in the valuation of banking businesses and their securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes. As
specialists in the securities of banking companies we have experience in, and
knowledge of, the valuation of banking enterprises. In the ordinary course of
our business as a broker-dealer, we may, from time to time, purchase securities
from, and sell securities to, Citizens and Crestar and as a market maker in
securities we may from time to time have a long or short position in, and buy or
sell, debt or equity securities of Citizens and Crestar for our own account and
for the accounts of our customers. To the extent we have any such position as of
the date of this opinion it has been disclosed to Citizens. We have acted as
financial advisor to the Board of Directors of Citizens in rendering this
fairness opinion and will receive a fee from Citizens for our services.
 
     In connection with this opinion, we have reviewed, among other things, the
Agreement; the Registration Statement on Form S-4, Annual Reports to
Stockholders of Crestar and Citizens for the three years ended December 31,
1995; certain interim reports to stockholders and Quarterly Reports on Form 10-Q
of Citizens and Crestar, and certain internal financial analyses and forecasts
for Citizens and Crestar prepared by management. We also have held discussions
with members of the senior management of Citizens and Crestar regarding the past
and current business operations, regulatory relationships, financial condition
and future prospects of their respective companies. In addition, we have
compared certain financial and stock market information for Citizens and Crestar
with similar information for certain other companies the securities of which are
publicly traded, reviewed the financial terms of certain recent business
combinations in the banking industry and performed such other studies and
analyses as we have considered appropriate. In conducting our review and
arriving at our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information provided to us or
publicly available and we have not assumed any responsibility for independently
verifying any of such information. We have relied upon the management of
Citizens and Crestar as to the reasonableness and achievability of the financial
and operating forecasts and projections (and the assumptions and bases therefor)
provided to us, and we have assumed that such forecasts and projections reflect
the best currently available estimates and judgments of Citizens and Crestar and
that such forecasts and projections will be realized in the amounts and in the
time periods currently estimated by such management. We have also assumed that
the aggregate allowances for loan losses for Citizens and Crestar are adequate
to cover such losses. In rendering our opinion, we have not made or obtained any
evaluations or appraisals of the property of Citizens or Crestar, nor have we
examined any individual credit files.
 
     We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following: (i)
the historical and current financial position and results of operations of
Citizens and Crestar;
 
                                      IV-1

<PAGE>
(ii) the assets and liabilities of Citizens and Crestar; and (iii) the nature
and terms of certain other merger transactions involving banks and bank holding
companies. We have also taken into account our assessment of general economic,
market and financial conditions and our experience in other transactions, as
well as our experience in securities valuation and our knowledge of the banking
industry generally. Our opinion is necessarily based upon conditions as they
exist and can be evaluated on the date hereof and the information made available
to us through the date hereof.
 
     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the exchange ration in the Merger is fair, from a financial point
of view, to the Common Stockholders of Citizens.
 
                                         Very truly yours,
 
                                         [KEEFE, BRUYETTE & WOODS, INC.]
