described herein.  The FTC Merger and the FFWM Merger are separate and
independent transactions.  Either Merger may be consummated whether or not the

Proposed Mergers

     Keystone and FTC.  At their respective Meetings, the shareholders of
Keystone and FTC will be asked to approve an Agreement and Plan of
Reorganization and a related Agreement and Plan of Merger (collectively, the
"FTC Plan of Merger") between Keystone and FTC.  The FTC Plan of Merger provides
for a merger of FTC into Keystone (the "FTC Merger") in which Keystone will
acquire all of the assets and liabilities of FTC, and the subsidiaries of FTC
will become Keystone subsidiaries.  See "FTC Plan of Merger--The FTC Merger."
As a result of the FTC Merger, the shareholders of FTC will become shareholders
of Keystone.  Each outstanding share of FTC Common Stock will be converted in
the FTC Merger into 1.65 shares of Keystone Common Stock, with cash to be paid
in lieu of any fractional share.  See "FTC Plan of Merger--Conversion of FTC
Common Stock."  On February ___, 1997, the closing sale price for Keystone
Common Stock on the NASDAQ National Market System was $_____ per share.

     Keystone and FFWM.  At the FFWM Special Meeting, the Shareholders of FFWM
will be asked to approve an Agreement and Plan of Merger between Keystone and
FFWM (the "FFWM Plan of Merger"). The FFWM Plan of Merger provides for the
merger (the "FFWM Merger") of FFWM into Keystone. It is contemplated that
contemporaneously with the FFWM Merger, FFWM's subsidiary, First Federal, will
be merged into American Trust Bank, one of Keystone's operating bank
subsidiaries (the "FFWM Bank Merger"). See "FFWM Plan of Merger--The FFWM
Merger." In the FFWM Merger, each outstanding share of FFWM Common Stock will be
converted into either (1) 1.29 shares of Keystone Common Stock, with cash to be
paid in lieu of any fractional share or (2) cash in an amount equal to 1.29
times the average of the closing bid prices for Keystone Common Stock on the
NASDAQ National Market System for the 20 trading days ending with the sixth
trading day preceding the closing date for the FFWM Merger. FFWM shareholders
may elect to receive either Keystone Common Stock or cash, but not both, subject
to certain limitations described herein. See "FFWM Plan of Merger--Elections by
FFWM Shareholders;" "FFWM Plan of Merger--Limitations on Effectiveness of
Elections;" and "FFWM Plan of Merger--Conversion of FFWM Common Stock." On
February ___, 1997, the closing bid price for Keystone Common Stock on the
NASDAQ National Market System was $_____ per share.


Elections by FFWM Shareholders

     FFWM shareholders may elect to receive in the FFWM Merger for each share of
FFWM Common Stock held of record either (1) 1.29 shares of Keystone Common
Stock, with cash to be paid in lieu of any fractional share (the "Stock
Election") or (2) cash in an amount equal to 1.29 times the average of the
closing bid prices for Keystone Common Stock on the NASDAQ National Market
System for the 20 trading days ending with the sixth trading day preceding the
closing date for the FFWM Merger (the "Cash Election").  Each FFWM shareholder
(other than nominees) must make the same Election for all FFWM shares held of
record.  The enclosed proxy card for FFWM shareholders contains a Form of
Election for designating either the Stock Election or the Cash Election. Persons
who become holders of record of FFWM Common Stock after the record date for the
FFWM Special Meeting may obtain a Form of Election by writing to First Financial
Corporation of Western Maryland, 118 Baltimore Street, Cumberland, Maryland
21502, Attention:  William C. Marsh, Executive Vice President and Chief
Financial Officer.  To be effective, a Form of Election must be received by FFWM
no later than 10:00 a.m., local time, on March 17, 1997.  FFWM shareholders who
fail to submit a Form of Election by this deadline will be deemed to have made
either the Stock Election or the Cash Election, as necessary to meet the
limitations described herein.  Upon this deadline Elections will become
irrevocable and will bind any transferee of the shares of the electing FFWM
shareholder.  See "FFWM Plan of Merger--Elections by FFWM Shareholders."

     The FFWM Plan of Merger requires that the aggregate market value of the
Keystone Common Stock to be issued under the Stock Election (1) shall be at
least equal to 55% of the total consideration payable by Keystone in the FFWM
Merger and (2) shall not (unless permitted by Keystone in its sole discretion)
exceed 60% of such total

                                      -vi-
<PAGE>
 
consideration except as necessary to assure that each FFWM shareholder shall be
deemed to have made either solely the Stock Election or solely the Cash
Election. If necessary to meet either of these limitations, the Elections made
by certain FFWM shareholders may be disregarded. See "FFWM Plan of
Merger--Limitations on Effectiveness of Elections."


Relationship of the Two Mergers

     The FTC Merger and the FFWM Merger are separate and independent
transactions.  Either Merger may be consummated whether or not the other is
approved by the shareholders entitled to vote thereon and whether or not the
other is consummated or is not consummated for any reason.  Therefore, in
considering whether to vote in favor of the FTC Merger, Keystone and FTC
shareholders should consider the effect of the FTC Merger both with and without
consummation of the FFWM Merger.  Similarly, in considering whether to vote in
favor of the FFWM Merger, FFWM shareholders should consider the effect of the
FFWM Merger both with and without consummation of the FTC Merger.

 
Reasons for the FTC Merger

     Keystone.  For Keystone, the FTC Merger will strengthen its market position
in central Pennsylvania and western Maryland and provide entry into new markets
in south central Pennsylvania.  Keystone believes that as a result of the FTC
Merger it will also be able to achieve operating economies and enhanced revenue
growth arising from a wider distribution of its products and services.
Consummation of the FTC Merger will create a company capable of competitively
providing a broad array of traditional and innovative banking products and
services to the resulting market.  The combination of the skills, resources and
services offered by Keystone and FTC will enable the resulting company to more
effectively compete with other full-service financial institutions in Keystone's
and FTC's respective markets. See "FTC Plan of Merger--Background of and Reasons
for the FTC Merger."
 
     FTC.  Over the past decade, as the pace of change within the banking
industry has accelerated and as competition from non-bank financial service
providers has increased, FTC carefully reviewed its strategic alternatives and
long-term goals and considered what steps should be taken to maintain and
enhance its competitive position.  In prior years this process led the FTC Board
of Directors to determine that it should continue its strategy of independence
and to seek growth internally and through acquisitions.

     While FTC as an independent entity historically has been able to implement
effective strategies to achieve strong financial performance, the changing
dynamics of the banking industry is likely to inhibit its ability to continue to
achieve comparable future performance.  The efficiencies of larger organizations
whose cost of doing business is on average less than that of FTC creates a
competitive disadvantage.  This disadvantage will most likely be amplified in
the future as the role of technology expands, placing greater emphasis on
substantial capital investment with a somewhat uncertain outcome.  Additionally,
the ability of nonbank competition to provide banking-related services with
substantially less regulatory oversight, the preclusion of banking institutions
to engage in certain financial product lines and the migration of traditional
bank products such as deposits to alternative investments likely will adversely
affect institutions such as FTC in their ability to generate competitive returns
to their shareholders.

     As a consequence of the foregoing factors, and considering FTC's strategic
geographical fit within Keystone's franchise, as well as the share exchange
ratio and the increased dividends and improved liquidity the transaction is
likely to provide to FTC's shareholders, the Board of Directors of FTC believes
that the FTC Merger will be in the best interests of FTC's shareholders and its
customers and the communities which it serves.  See "FTC Plan of
Merger--Background of and Reasons for the FTC Merger."

                                     -vii-
<PAGE>
 
Reasons for the FFWM Merger

     FFWM.  During August 1996, the FFWM Board of Directors determined that it
was appropriate to explore and evaluate the various options available to FFWM to
maximize shareholder value, including the possible sale of FFWM.  To this end,
the Board of Directors engaged the investment banking firm of Alex. Brown & Sons
Incorporated ("Alex. Brown") to assist FFWM in its evaluation.  Alex. Brown
conducted extensive efforts to identify potential acquirors and assist the Board
of Directors in evaluating the proposals received, which ultimately resulted in
the selection of Keystone as the acquiror of FFWM.  The FFWM Board of Directors
believes that the FFWM Merger is in the best interests of FFWM's shareholders
and the communities in which FFWM operates. In reaching this determination 
FFWM's Board of Directors evaluated numerous factors and obtained a written
opinion from Alex. Brown to the effect that the consideration to be paid to
shareholders of FFWM in connection with the FFWM Merger is fair, from a
financial point to view, to FFWM's shareholders. For a more detailed discussion
of the reasons for the FFWM Merger see "FFWM Plan of Merger--Background of and
Reasons for the FFWM Merger."

     Keystone.  Through the merger of FFWM's subsidiary, First Federal, with
Keystone's subsidiary, American Trust Bank, Keystone seeks to increase American
Trust Bank's market penetration in the areas currently served by both banks and
to extend American Trust Bank's market geographically.  Keystone hopes following
the merger to retain First Federal's depositors and consumer borrowers and
thereby increase its retail customer base.  In turn, American Trust Bank will
have the opportunity to expand banking relationships with its new customers by
offering them products and services not presently offered by First Federal.
Keystone believes that the merger may enable it to realize cost efficiencies at
the same time that it expands its customer base.  Finally, the merger will
enable American Trust Bank to expand its market geographically, both in the
counties in which both banks have offices and into the city of Hagerstown,
Maryland, where First Federal currently has an office, but American Trust Bank
does not.  See "FFWM Plan of Merger--Background of and Reasons for the FFWM
Merger."


Opinions of Financial Advisors

     The investment banking firm of Danielson Associates Inc. has rendered an
opinion to Keystone dated February ___, 1997 that the terms of the FTC Merger
are fair, from a financial point of view, to Keystone and its shareholders.  The
investment banking firm of Berwind Financial Group, L.P. has rendered an opinion
to FTC dated February ___, 1997 that the terms of the FTC Merger are fair,
from a financial point of view, to FTC shareholders.  The investment banking
firm of Alex. Brown & Sons Incorporated has rendered an opinion to the FFWM
Board of Directors dated November 26, 1996 that the total consideration to be
received by FFWM shareholders in the FFWM Merger is fair, from a financial point
of view, to FFWM shareholders.  These opinions are attached as Annexes I, II and
III to this Joint Proxy Statement/Prospectus and should be read in their
entirety for information as to the matters considered and the assumptions made
in rendering such opinions.  See "FTC Plan of Merger--Opinion of Keystone
Financial Advisor," "FTC Plan of Merger--Opinion of FTC Financial Advisor" and

Keystone requires the affirmative vote of a majority of the votes cast on the
proposal by the holders of Keystone Common Stock.  An abstention or a broker

Interests of Certain Persons in the Transactions

     FTC Merger.  In connection with the FTC Merger, Keystone has entered into
an employment agreement with Ray L. Wolfe, the Chairman of the Board and Chief
Executive Officer of FTC.  The agreement provides for Mr. Wolfe's employment by
Keystone for three years following the FTC Merger at an annual compensation of
$350,000 and for his retention as a consultant thereafter until August 15, 2003
at an annual compensation of $177,000.  Keystone has also agreed to honor FTC's
and its subsidiaries' obligations to indemnify their directors and officers, and
charter and bylaw provisions limiting the liability of directors, with respect
to events occurring prior to the FTC Merger and to provide employees of FTC and
its subsidiaries with credit for their prior service with FTC in determining
eligibility and vesting under Keystone's employee benefit plans.  See "FTC Plan
of Merger--Interests of Certain Persons in the Transaction."

     FFWM Merger.  In consideration of their being available to Keystone for
advisory services, Keystone has agreed to pay each director of FFWM who
continues to serve until the FFWM Merger an amount equal to the fees paid to the
director by FFWM during the year preceding the FFWM Merger.  These amounts,
which are estimated to range between $12,200 and $13,400 per director, will be
reduced by any fees received for service as a director of American Trust Bank.

     FFWM and First Federal are parties to an employment agreement with Patrick
J. Coyne, Chairman of the Board, President and Chief Executive Officer, and
severance agreements with Kenneth W. Andres, William C. Marsh and R. Craig Pugh,
three Executive Vice Presidents.  Under these agreements, upon consummation of
the FFWM Merger and in satisfaction of the employers' obligations under the
terms of the agreements and existing stock option and incentive plan agreements,
Messrs. Coyne, Andres, Marsh and Pugh will receive pre-tax severance payments in
the amounts of [$1,334,348, $421,827, $344,152 and $445,594], respectively. The
employment of each of Messrs. Coyne, Andres, Marsh and Pugh will terminate
effective on the effective date of the FFWM Merger, and none of these officers
will have any continuing employment with Keystone or American Trust Bank
following the effective date.

     Keystone has agreed in the FFWM Plan of Merger to honor FFWM's obligations
to indemnify the directors and officers of FFWM and its subsidiaries, and
charter and bylaw provisions limiting the liability of FFWM directors, with
respect to events occurring prior to the FFWM Merger and to provide FFWM's
directors and officers with certain liability insurance coverage for three years
following the FFWM Merger.  It has also agreed to pay FFWM directors and
officers who hold unexercised stock options under FFWM's stock incentive plan,
in exchange for the cancellation of their options, an amount equal to the net
amount that would have been received under the Cash Election if the option had
been exercised prior to the FFWM Merger. Finally, Keystone has agreed that
employees of FFWM and its subsidiaries who become Keystone employees will be
entitled to participate in Keystone employee benefit plans, with credit for
their prior service with FFWM in determining eligibility and vesting, and that
employees of FFWM and its subsidiaries with at least one year of service prior
to the FFWM Merger will be entitled to participate in a Keystone severance plan
that will provide severance benefits if the employee's employment is terminated
in certain circumstances upon or following the FFWM Merger. See "FFWM Plan of
Merger--Interests of Certain Persons in the Transaction."

Warrant/Option Agreements

     FTC Warrant Agreement.  In connection with the FTC Plan of Merger, FTC has
entered into an agreement granting Keystone a warrant to purchase up to 19.9% of
the outstanding FTC Common Stock, at an exercise price of $43.725 per share,
upon the occurrence of certain events.  In general, the events which would
permit Keystone to exercise its warrant would involve an attempt by a third
person to gain control of FTC.  The Warrant Agreement is designed to compensate
Keystone for its risks, costs and expenses and the commitment of resources
associated with the FTC Plan of Merger in the event the FTC Merger is not
consummated due to an attempt by a third person to gain control of FTC.  The
Warrant Agreement may discourage third persons from making competing offers to
acquire FTC and is intended to increase the likelihood that the FTC Plan of
Merger will be consummated in accordance with its terms.  Exercise of the
warrant for  more than 5% of the outstanding FTC Common Stock would be subject
to the approval of regulatory authorities.  See "FTC Plan of Merger--Warrant
Agreement."

     FFWM Option Agreement.  In connection with the FFWM Plan of Merger, FFWM
has entered into an agreement granting Keystone an option to purchase up to
16.6% of the outstanding FFWM Common Stock, at an exercise price of $34.19 per
share, upon the occurrence of certain events.  In general, the events which
would permit Keystone to exercise its option would involve an attempt by a third
person to gain control of FFWM.  The Option Agreement is designed to compensate
Keystone for its risks, costs and expenses and the commitment of resources
associated with the FFWM Plan of Merger in the event the FFWM Merger is not
consummated due to an attempt by a third person to gain control of FFWM.  The
Option Agreement may discourage third persons from making competing offers to
acquire FFWM and is intended to increase the likelihood that the FFWM Plan of
Merger will be consummated in accordance with its terms.  Exercise of the option

Joint Proxy Statement/Prospectus as Annex IV.  Failure to follow such provisions
precisely may result in a loss of dissenters' rights.  See "FFWM Plan of
Merger--Dissenters' Rights of FFWM Shareholders."


Differences in Shareholder Rights

     The rights of the holders of Keystone Common Stock differ in certain
respects from those of the holders of FTC Common Stock and FFWM Common Stock.

     FTC Common Stock.  While for both FTC and Keystone supermajority
shareholder votes are required to approve certain mergers and other transactions
and certain amendments to the Articles of Incorporation or Bylaws, the types of
transactions or amendments subject to the special vote requirements and the
votes required for approval differ between the two companies.  While both FTC
and Keystone have classified Boards of Directors, there are differences in the
rights of shareholders of the two companies to increase or decrease the size of
the Board, to fill vacancies and to nominate and remove directors.  Unlike FTC,
Keystone has established a shareholder rights plan which may discourage outside
persons from attempting to acquire control of Keystone.  While both FTC and
Keystone are subject to certain provisions of the Pennsylvania Business
Corporation Law which may make an attempt to acquire control of the corporation
more difficult, Keystone has elected to opt out from coverage of some of these
provisions.  Unlike FTC, Keystone has an authorized class of preferred stock
which, if issued, could affect the rights of the holders of Keystone Common
Stock.  For a more detailed discussion of the differences between the rights of
the holders of FTC Common Stock and those of the holders of Keystone Common
Stock, see "Comparison of Keystone Common Stock and FTC Common Stock."

     FFWM Common Stock.  While for both FFWM and Keystone supermajority
shareholder votes are required to approve certain mergers and other transactions
with a substantial shareholder and certain charter and bylaw amendments, the
types of transactions and amendments subject to the special vote requirements
and the votes required for approval differ between the two companies.  While
both FFWM and Keystone have classified Boards of Directors, there are
differences in the rights of shareholders of the two companies to nominate and
remove directors.  Keystone has established a shareholder rights plan which may
discourage outside persons from attempting to acquire control of Keystone.  FFWM
does not have a shareholder rights plan but does restrict the ability of any
person to vote more than 10% of its outside shares.  While the statutes
governing both Keystone and FFWM contain additional provisions that may
discourage takeover attempts by outside persons, the provisions of the two
statutes are not the same.  For a more detailed discussion of the differences
between the rights of the holders of FFWM Common Stock and those of the holders
of Keystone Common Stock, see "Comparison of Keystone Common Stock and FFWM
Common Stock."


Regulatory Approvals

     The FTC Merger requires approval by the Board of Governors of the Federal
Reserve System, the Pennsylvania Department of Banking and the Maryland Bank
Commissioner.  The FFWM Bank Merger, which is a condition to the FFWM Merger,
requires approval by the Office of the Comptroller of the Currency ("OCC").
Applications for these approvals will be filed and are expected to be approved,
although no assurances may be given as to whether or when such approvals may be
received.

Conditions; Amendment; Termination

     In addition to shareholder and regulatory approval, consummation of each
Merger is contingent upon the receipt of certain tax opinions and the
satisfaction of a number of other conditions.  See "FTC Plan of Merger--
Conditions to the FTC Merger" and "FFWM Plan of Merger--Conditions to the FFWM
Merger."  Notwithstanding prior shareholder approval, either Plan of Merger may
generally be amended in any respect other than the ratio for converting FTC
Common Stock into Keystone Common Stock in the FTC Merger or the formulas for
converting FFWM Common Stock into Keystone Common Stock or cash in the FFWM
Merger.

     The FTC Plan of Merger may be terminated, and the FTC Merger abandoned,
notwithstanding prior shareholder approval, by mutual agreement of Keystone and
FTC or by either of them in the event of a material breach by the other party,
the failure of the shareholders of either party to approve the FTC Merger, the
denial of a required regulatory approval or failure to satisfy the conditions to
the FTC Merger prior to December 31, 1997.  See "FTC Plan of Merger--Amendment,
Waiver and Termination."

     The FFWM Plan of Merger may be terminated, and the FFWM Merger abandoned,
notwithstanding prior shareholder approval, by mutual agreement of Keystone and
FFWM or by either of them in the event of a material breach by the other party,
the failure of the shareholders of FFWM to approve the FFWM Merger, the denial
of a required regulatory approval or failure to consummate the FFWM Merger prior
to November 26, 1997. The FFWM Plan of Merger may also be terminated by FFWM if
the average closing bid price for Keystone Common Stock shall be less than
$21.20 for the period of 20 consecutive trading days ending with the date of
approval of the FFWM Bank Merger by the OCC or by Keystone if the average
closing bid price for Keystone Common Stock for such period shall be greater
than $31.80.  In the event Keystone elects to terminate for this reason, FFWM
may prevent such termination by electing to proceed with the FFWM Merger at a
reduced exchange ratio.  See "FFWM Plan of Merger--Amendment, Waiver and
Termination."


Effective Dates of the Mergers

     It is presently anticipated that if the FTC Plan of Merger is approved by
the shareholders of Keystone and FTC, the FTC Merger will become effective in
the second quarter of 1997.  However, there can be no assurance that all
conditions necessary to the consummation of the FTC Merger will be satisfied or,
if satisfied, that they will be satisfied in time to permit the FTC Merger to
become effective at the anticipated time.  See "FTC Plan of Merger--Effective
Date of the FTC Merger."

     It is presently anticipated that if the FFWM Plan of Merger is approved by
the shareholders of FFWM, the FFWM Merger will become effective in the second
quarter of 1997.  However, there can be no assurance that all conditions
necessary to the consummation of the FFWM Merger will be satisfied or, if
satisfied, that they will be satisfied in time to permit the FFWM Merger to
become effective at the anticipated time.  See "FFWM Plan of Merger--Effective
Date of the FFWM Merger."


Exchange of Certificates

     Instructions on how to effect the exchange of FTC Common Stock certificates
for Keystone Common Stock certificates or the exchange of FFWM Common Stock
certificates for Keystone Common Stock certificates or cash will be sent as
promptly as practicable after the FTC Merger or FFWM Merger becomes effective to
each shareholder of record of FTC or FFWM immediately prior to such Merger.
Shareholders should not send in stock certificates until they receive written
instructions to do so.

Keystone Stock Repurchase Program

     On November 16, 1995, as part of its capital management planning process,
Keystone's Board of Directors authorized a common share repurchase program of up
to 1.5 million shares of Keystone Common Stock. However, any determination as to
the amount and timing of share repurchases would be subject to an evaluation of
alternative investment returns and overall capitalization levels.  Shares
repurchased under the program were to be held as treasury stock for such
corporate purposes as may be determined, including to fund Keystone's existing
employee benefit and share related plans.  In order to satisfy pooling-of-
interests accounting requirements associated with the FTC Merger, on January 23,
1997 Keystone's Board of Directors amended the share repurchase program to limit
the maximum number of shares to be reacquired to 1.2 million and to provide that
the program shall terminate no later than the closing date for the FTC Merger.
At December 31, 1996, Keystone had 320,000 shares of Keystone Common Stock held
in treasury.

     In a separate action, at the January 23, 1997 meeting of the Keystone Board
of Directors, the Board authorized the repurchase of up to 1.5 million shares of
Keystone Common Stock for issuance in the FFWM Merger.  The FFWM Merger will be
accounted for as a purchase business combination.  This repurchase program will
be completed no later than the closing date for the FFWM Merger.


     [NOTE:  Prior to the mailing to shareholders, a "Subsequent Events" section
will be added to the Summary concerning Keystone's and FTC's announcements of
results for the year ended December 31, 1996 and FFWM's announcement of results
for its fiscal quarter ended December 31, 1996.]

Comparative Per Share Data--(unaudited)

     The following table sets forth for the periods indicated (i) historical
earnings, book values and dividends per share for Keystone, FTC and FFWM Common
Stock, (ii) pro forma comparative earnings and book values per share for

(1) The Keystone pro forma per share information is prepared on the basis of the
    pro forma combined financial information, which includes the impact of the

    Information."  The FTC pro forma equivalent per share information represents
    the Keystone and FTC pro forma book values and net income per share and the
    Keystone historical dividends per share, multiplied by the FTC Merger
    exchange ratio of 1.65 shares of Keystone Common Stock for each share of FTC
    Common Stock.  The FFWM pro forma equivalent per share information
    represents the Keystone historical and the Keystone and FTC pro forma book
    values and net income per share and the Keystone historical dividends per

    Keystone Common Stock for each share of FFWM Common Stock.  Keystone
    financial information for the three years ended December 31, 1993 has been
    restated to reflect mergers with The Frankford Corporation, WM Bancorp and
    Elmwood Bancorp, Inc., which occurred in 1994, and FTC financial information
    for the fours years ended December 31, 1994 has been restated to reflect the
    acquisition of Washington County National Bank, which occurred in 1995.
    These transactions were accounted for as poolings of interests.

(2) Keystone per share information has been restated to reflect three-for-two
    stock split in the form of a 50% stock dividend declared in 1996.  FTC per

(4) While Keystone is not obligated to pay cash dividends, the Board of
    Directors presently intends to continue the policy of paying quarterly cash
    dividends.  Future dividends will depend, in part, upon the earnings and
    financial condition of Keystone.

Purposes of the Special Meetings

     Keystone and FTC Meetings:  Approval of FTC Plan of Merger.  At their
respective Special Meetings, the shareholders of Keystone and FTC will be asked
to consider and vote upon a proposal to approve an Agreement and Plan of
Reorganization and a related Agreement and Plan of Merger, each dated as of
December 19, 1996 (collectively, the "FTC Plan of Merger"), between FTC and
Keystone.  As more fully described below under "FTC Plan of Merger," the FTC
Plan of Merger provides for a merger of FTC into Keystone (the "FTC Merger").
In the FTC Merger, each outstanding share of FTC Common Stock will be converted
into the right to receive 1.65 shares of Keystone Common Stock.

     Keystone has received an opinion of the investment banking firm of
Danielson Associates Inc. that the terms of the FTC Merger are fair to the
shareholders of Keystone from a financial point of view.  See "FTC Plan of
Merger--Opinion of Keystone Financial Advisor."

     FTC has received an opinion of the investment banking firm of Berwind
Financial Group, L.P. that the terms of the FTC Merger are fair to the
shareholders of FTC from a financial point of view.  See "FTC Plan of Merger--
Opinion of FTC Financial Advisor."

     THE BOARDS OF DIRECTORS OF KEYSTONE AND FTC BELIEVE THAT THE FTC MERGER IS
IN THE BEST INTERESTS OF THEIR RESPECTIVE SHAREHOLDERS, AND EACH UNANIMOUSLY
RECOMMENDS THAT ITS SHAREHOLDERS VOTE TO APPROVE THE FTC PLAN OF MERGER.

     FFWM Special Meeting:  Approval of FFWM Plan of Merger.  At the FFWM
Special Meeting, the shareholders of FFWM will be asked to consider and vote
upon a proposal to approve an Agreement and Plan of Merger dated as of November
26, 1996 between FFWM and Keystone (the "FFWM Plan of Merger").  As more fully
described below under "FFWM Plan of Merger," the FFWM Plan of Merger provides
for a merger of FFWM into Keystone (the "FFWM Merger").  In the FFWM Merger,
each outstanding share of FFWM Common Stock (other than shares subject to
dissenters' rights) will be converted into the right to receive, at the election
of the holder, either (1) 1.29 shares of Keystone Common Stock or (2) cash in an
amount equal to 1.29 times the average of the closing bid prices for Keystone
Common Stock on the NASDAQ National Market System for the 20 trading days ending
with the sixth trading day preceding the closing date for the FFWM Merger.  The
elections by the holders of FFWM Common Stock are subject to certain limitations
described below as to the minimum and maximum numbers of shares of FFWM Common
Stock that may be converted into Keystone Common Stock.  See "FFWM Plan of
Merger--Limitations on Effectiveness of Elections."  It is contemplated that
contemporaneously with the FFWM Merger, FFWM's bank subsidiary, First Federal
Savings Bank of Western Maryland, will be merged into American Trust Bank, one
of Keystone's operating bank subsidiaries.

     FFWM has received an opinion of the investment banking firm of Alex. Brown
& Sons Incorporated that the total consideration to be received by FFWM
shareholders in the FFWM Merger is fair, from a financial point of view, to FFWM
shareholders.  See "FFWM Plan of Merger--Opinion of FFWM Financial Advisor."

     THE BOARD OF DIRECTORS OF FFWM BELIEVES THAT THE FFWM MERGER IS IN THE BEST
INTERESTS OF THE SHAREHOLDERS OF FFWM AND UNANIMOUSLY RECOMMENDS THAT FFWM
SHAREHOLDERS VOTE TO APPROVE THE FFWM PLAN OF MERGER.


Voting and Revocation of Proxies

     All properly executed proxies not theretofore revoked will be voted at the
Special Meetings or any adjournments thereof in accordance with the instructions
thereon.  Keystone and FTC proxies containing no voting instructions will be
voted in favor of approval of the FTC Plan of Merger.  FFWM proxies containing
no voting instructions will be voted in favor of approval of the FFWM Plan of
Merger.  As to any other matter brought before

                                      -2-
<PAGE>
 
a Special Meeting and submitted to a shareholder vote, proxies will be voted in
accordance with the judgment of the proxyholders named thereon.

     A shareholder who has executed and returned a proxy may revoke it at any
time before it is voted by filing with the Secretary of Keystone, FTC or FFWM,
as the case may be, written notice of such revocation or a later dated proxy or
by attending the appropriate Special Meeting and voting in person.  Attendance
at a Special Meeting will not, of itself, constitute a revocation of a proxy.

subsidiaries, acting in a fiduciary capacity for various trusts and estates,

6.25% of the outstanding shares).  Of these shares, the banks have sole voting
power over 4,525 shares, share voting power with other persons over 98,098
shares, have sole investment power over 1,834,741 shares and share investment
power with other persons over 133,730 shares.  Keystone does not know of any
other person who has or shares voting and/or investment power over more than 5%
of the outstanding Keystone Common Stock.

     As of January 1, 1997 FTC's trust company subsidiary, Financial Trust
Services Company, acting in a fiduciary capacity for various trusts and estates,
beneficially owned an aggregate of 669,923 shares of FTC Common Stock, or
approximately 7.9% of the outstanding FTC Common Stock.  Of these shares, the
trust company has sole voting power over 528,978 shares and shares voting power
with other persons over 121,747 shares.  The trust company had no voting power
over 19,198 shares.

     In addition to shares held in a fiduciary capacity, as of February 3, 1997
Keystone owned approximately [31,400] shares of FTC Common Stock, and a
subsidiary of FTC owned approximately [937] shares of Keystone Common Stock.

     It is anticipated that shares of Keystone or FTC Common Stock over which
Keystone, FTC or their subsidiaries have sole voting power will be voted in
favor of approval of the FTC Plan of Merger.  Shares as to which the
subsidiaries share voting power will be voted in consultation with the other
persons having voting power over such shares.


Solicitation of Proxies

     In addition to solicitation by mail, directors, officers and employees of
Keystone, FTC and FFWM may solicit proxies from the shareholders of Keystone,
FTC and FFWM, respectively, in person or by telephone or otherwise for no
additional compensation.  Brokerage houses, nominees, fiduciaries and other
custodians will be requested to forward proxy soliciting materials to beneficial
owners of shares held of record by them and will be reimbursed for their
reasonable expenses.  Keystone, FTC and FFWM will each bear its own expenses in
connection with the solicitation of proxies for its Special Meeting.

     Keystone has retained the firm of Corporate Investor Communications, Inc.
("CIC"), 111 Commerce Road, Carlstadt, New Jersey 07072-2586, to assist in the
solicitation of proxies for the Keystone Special Meeting.  For these services
CIC will receive a fee of $5,000, plus reimbursement for its out-of-pocket
disbursements.  If requested to contact individual registered holders and
nonobjecting beneficial owners, CIC will charge a fee of $3.00 per holder
contacted, which fee includes directory assistance and related telephone
expenses.  Keystone estimates the total cost of the services of CIC to be
approximately $9,000.

     FFWM has retained Morrow & Co., Inc., 909 Third Avenue, 20th Floor, New
York, New York 10022, a professional proxy soliciting firm, to assist in the
solicitation of proxies and for related services.  FFWM will pay Morrow & Co.,
Inc. a fee of $5,000 and has agreed to reimburse it for its reasonable out-of-
pocket expenses.

                               FTC PLAN OF MERGER
                                        
     This section of the Joint Proxy Statement/Prospectus describes certain of
the more important aspects of the FTC Plan of Merger.  The following description
does not purport to be complete and is qualified in its entirety by reference to
the FTC Plan of Merger, which has been filed with the SEC as an exhibit to the
Registration Statement.  The FTC Plan of Merger is incorporated in this Joint
Proxy Statement/Prospectus by reference to such filing and is available upon
request.  See "Available Information."


The FTC Merger

     The FTC Plan of Merger provides for a merger of Keystone and FTC in which
Keystone will be the surviving corporation.  As a result of the FTC Merger,
Keystone will acquire all of the assets and liabilities of FTC, FTC's
subsidiaries will become subsidiaries of Keystone, and FTC will cease to exist
as a separate corporation.

     In the FTC Merger, the shareholders of FTC will become shareholders of
Keystone.  Each of the approximately [8,532,131] outstanding shares of FTC
Common Stock will be converted into the right to receive 1.65 shares of Keystone
Common Stock, with cash to be paid in lieu of any fractional share.  See
"Conversion of FTC Shares."  The FTC Merger will not result in any change in the
shares of Keystone Common Stock held by the current Keystone shareholders.

     Keystone is a bank holding company with its principal executive offices in
Harrisburg, Pennsylvania.  Its bank subsidiaries are American Trust Bank,
Cumberland, Maryland, Frankford Bank, N.A., Horsham, Pennsylvania; Keystone
National Bank, Lancaster, Pennsylvania; Mid-State Bank and Trust Company,
Altoona, Pennsylvania; Northern Central Bank, Williamsport, Pennsylvania; and
Pennsylvania National Bank and Trust Company, Pottsville, Pennsylvania, which
operate a combined total of 140 banking offices in central and southeastern
Pennsylvania, western Maryland and northeastern West Virginia.  It also has a
number of nonbank subsidiaries and divisions which provide services to Keystone
and its customers, including brokerage, investment, mortgage banking, leasing
and insurance.  See "Summary--The Parties--Keystone" and "Keystone Documents
Incorporated by Reference."

     FTC is a bank holding company with its principal executive offices in
Carlisle, Pennsylvania.  Its bank subsidiaries are Financial Trust Company,
Carlisle, Pennsylvania; Chambersburg Trust Company, Chambersburg, Pennsylvania;
First National Bank and Trust Co., Waynesboro, Pennsylvania; and Washington
County National Bank, Williamsport, Maryland, which operate a combined total of
48 banking offices in south central Pennsylvania and western Maryland.  FTC also
has two nonbank subsidiaries which provide trust services and insurance to FTC
customers.  See "Summary--The Parties--FTC" and "FTC Documents Incorporated by
Reference."  Following the FTC Merger, FTC's subsidiaries will be wholly owned
subsidiaries of Keystone.


Background of and Reasons for the FTC Merger

     FTC.  As the pace of change within the banking industry has accelerated
over the past decade, and as competition from non-bank financial service
providers has increased, FTC carefully reviewed its strategic alternatives and
long-term goals and took appropriate steps to maintain and enhance its
competitive position.  As part of this process, FTC confirmed its commitment to
the Pennsylvania and Maryland markets in which it operates by building on
existing strengths and expanding into neighboring markets, both through internal
growth as well as through identifying appropriate acquisition opportunities.

     FTC's Board of Directors has, over a number of years, periodically reviewed
strategic alternatives including (i) remaining independent and continuing its
strategy of internal growth and expansion through

                                      -4-
<PAGE>
 
acquisitions, (ii) engaging in a merger-of-equals type transaction and (iii)
undertaking a strategic combination with a larger banking organization.  In
prior years, FTC's Board determined that it should continue its strategy of
independence and to seek growth internally and through acquisitions.  It was in
this context that FTC entered into an agreement to acquire Washington County
National Bank in 1995. However, such opportunities are increasingly limited in
FTC's market area.

     While FTC historically has been able to implement effective strategies to
achieve strong financial performance, the changing dynamics of the banking
industry are likely to inhibit the company's ability to continue to achieve
comparable future performance.  The efficiencies of larger organizations whose
cost of doing business is on average less than FTC's creates a competitive
disadvantage.  This disadvantage will most likely be amplified in the future as
the role of technology expands, placing greater emphasis on substantial capital
investment with a somewhat uncertain outcome.  Additionally, the ability of
nonbank competition to provide banking-related services with substantially less
regulatory oversight, the preclusion of banking institutions to engage in
certain financial product lines and the migration of traditional bank products
such as deposits to alternative investments likely will adversely affect
institutions such as FTC in their ability to generate competitive returns to
their shareholders.

     Messrs. Wolfe and Campbell, the chief executive officers of FTC and
Keystone, respectively, have known each other for a number of years as a result
of the geographic proximity of the two institutions and their service with
various community and bank industry groups.  On occasion, they have previously
discussed, on an informal basis, the strategic direction of their respective
institutions, as well as the implications of consolidation within the banking
industry and increased competition from nonbank service providers.

     In early 1996, Messrs. Wolfe and Campbell discussed the implications of
1995's record level of merger and acquisition activity on, in particular, the
markets in which they operate.  At this time, they decided to explore, at least
conceptually, whether a combination of FTC and Keystone was feasible from a
financial, business and cultural perspective.  These discussions were terminated
during the month of April, however, as FTC decided to continue its existing
strategic plan.

     During the month of November, Messrs. Wolfe and Campbell once again resumed
conversations concerning a potential combination between the two companies.  Due
to appreciation in Keystone's stock price since early 1996 and increased
earnings from FTC, they discussed the possibility that a transaction between
the two companies might be possible.

     On November 19th, Mr. Wolfe met with FTC's Planning Committee, a
subcommittee of the Board consisting of Mr. Wolfe and five other board members,
to discuss his recent conversations with Mr. Campbell.  After deliberation, the
Planning Committee decided that it might be in FTC's shareholders' best interest
to consider pursuing a combination with Keystone.  The Planning Committee then
decided to invite representatives of Keystone to make a presentation to FTC's
Board of Directors to discuss the company's operating philosophy, strategic
direction, current stock valuation and other various areas of interest.

     Upon the request of the Planning Committee, FTC held a special board
meeting on November 25th at which representatives of Berwind Financial Group,
L.P. ("Berwind") and Keystone made a formal presentation.  Also in attendance
were representatives of FTC's legal advisor, McNees, Wallace & Nurick.  Berwind
began its presentation by providing an overview of the banking industry in
general, citing various trends and developments including among others,
competition for banking assets, migration of banking deposits, importance of
technology and consolidation.  Next, Berwind addressed FTC's position within the
industry, comparing various performance ratios with certain comparable peer
groups. Berwind then provided similar commentary on Keystone.  Lastly, Berwind
addressed FTC's strategic position from a financial point of view with respect
to (i) remaining independent and (ii) a possible affiliation with Keystone.
Thereafter, representatives of Keystone joined the meeting and provided an
overview of their institution, including financial, operational and stock
performance.  In addition, the representatives discussed FTC's potential
strategic and geographical fit within Keystone's franchise.  After their
presentation, Keystone's representatives were excused from the meeting.  At
this time FTC's Board discussed various considerations relevant to forming a
strategic alliance with Keystone.  After deliberation, the

                                      -5-
<PAGE>
 
Board unanimously agreed to explore further a possible affiliation with
Keystone.  In addition, pending further discussions with Keystone, the Board of
Directors decided not to authorize conversations with any other party.

     Discussions between the senior staffs of FTC and Keystone occurred
subsequent to the November 25th Board meeting.  These meetings and conversations
focused on quantifying what synergies and revenue enhancements would be
realizable in a combination of the two companies.  In addition, conversations
were held concerning FTC's on-going role in the pro forma entity, namely, board
and managerial representation.  Following these discussions, Keystone indicated
its willingness to continue negotiations based upon a 1.60 stock exchange ratio.

     After Keystone improved the proposed exchange ratio to 1.65 as a result of
further negotiation, the Planning Committee on December 12th met with
representatives of Berwind to evaluate the proposed transaction from a financial
point of view.  Berwind discussed with the Planning Committee, among other
things, the ability of FTC to generate sufficient returns to its shareholders
both internally and externally and to improve shareholder liquidity in light of
increasing bank and non-bank competition.  Berwind then outlined with the
Committee certain financial considerations of the proposed transaction based
upon the exchange ratio.  Discussions focused on the proposed price, potential
rates of return and improved liquidity the transaction would provide FTC's
shareholders.  After consultation with Berwind's representatives, the Planning
Committee decided that, although a further effort should be made to obtain a
greater exchange ratio, a transaction based upon the proposed exchange ratio
warranted FTC's Board of Directors' review.

     On December 16th, a special meeting of the FTC Board of Directors was held
to discuss the results of discussions held with Keystone.  Representatives of
McNees, Wallace & Nurick, FTC's legal counsel, and Berwind were in attendance.
Mr. Wolfe updated the Board on the result of senior management's discussions
with Keystone.  At that time, representatives of Berwind made an extensive
presentation and distributed materials to the directors of FTC relating to
current banking markets, industry trends and conditions, the current value of
the future prospects for FTC as an independent entity and the value of the
merger and a comparison of the exchange ratio to those used in comparable bank
mergers.  Following Berwind's presentation, counsel explained in detail various
legal and regulatory aspects of the transaction.  At the conclusion of these
presentations, extensive discussions followed involving the Board of Directors,
Berwind and counsel.  Upon the conclusion of these discussions, the Board
authorized management to negotiate the terms of a definitive agreement with
Keystone based upon a 1.65 exchange ratio.  Mr. Wolfe advised the Board that it
would be important that the process move quickly in order to preserve
confidentiality.

     On the afternoon of December 19th, 1996, FTC's Board of Directors
reconvened to review the proposed Agreement and Plan of Reorganization and
other related transactional documents.  At the meeting, representatives of
Berwind and McNees, Wallace & Nurick were present to discuss in detail, among
other things, the potential financial and strategic benefits of the proposed
transaction, the fairness of the transaction to FTC's shareholders and the
anticipated tax and accounting treatment of the proposed transaction.  After
being apprised of the results of the continuing negotiations to finalize the
documentation and consideration of related information, FTC's Board, by
unanimous vote of all directors present, approved the Agreement and Plan of
Reorganization and the transactions contemplated thereby.

     Keystone.  For Keystone, the FTC Merger will strengthen its market position
in central Pennsylvania and western Maryland and provide entry into new markets
in south central Pennsylvania.  Keystone believes that as a result of the FTC
Merger it will also be able to achieve operating economies and enhanced revenue
growth arising from a wider distribution of its products and services.
Consummation of the FTC Merger will create a company capable of competitively
providing a broad array of traditional and innovative banking products and
services to the resulting market.  These products and services include complete
banking services, discount brokerage, leasing, investment advisory services,
mutual funds, annuities, mortgage services and automobile dealer financing.  The
combination of the skills, resources and services offered by Keystone and FTC
will enable the resulting company to more effectively compete with other full-
service financial institutions in Keystone's and FTC' respective markets.

Required Votes; Management Recommendations

     Keystone.  Approval by the Keystone shareholders of the FTC Plan of Merger
requires the affirmative votes a majority of the votes cast by the holders of
Keystone Common Stock, voting in person or by proxy at the Keystone Special
Meeting.  An abstention or a broker non-vote is not a vote cast and will not be
counted in determining the number of votes required for approval by the
shareholders of Keystone.  THE BOARD OF DIRECTORS OF KEYSTONE UNANIMOUSLY
RECOMMENDS THAT KEYSTONE SHAREHOLDERS VOTE "FOR" APPROVAL OF THE FTC PLAN OF
MERGER.

     FTC.  Approval by the FTC shareholders of the FTC Plan of Merger requires
the affirmative votes of the holders of at least two-thirds of the outstanding
shares of FTC Common Stock, voting in person or by proxy at the FTC Special
Meeting.  Because FTC shareholder approval requires the affirmative votes of
two-thirds of all outstanding FTC shares, an abstention or a broker non-vote
will have the same legal effect as a vote by a FTC shareholder against approval
of the FTC Plan of Merger.  THE BOARD OF DIRECTORS OF FTC UNANIMOUSLY RECOMMENDS
THAT FTC SHAREHOLDERS VOTE "FOR" APPROVAL OF THE FTC PLAN OF MERGER.


Voting Agreements

     In connection with the FTC Plan of Merger, the directors of FTC have
entered into agreements to vote certain shares of FTC Common Stock beneficially
owned by them in favor of the FTC Merger.  The directors of FTC have agreed with
Keystone that they will vote in favor of the FTC Merger all shares of FTC Common
Stock owned by them as individuals or (to the extent of their proportionate
voting interest) jointly with other persons, and that they will use their best
efforts to cause any other shares of FTC Common Stock over which they have or
share voting power to be voted in favor of the FTC Merger.  In the aggregate,
these agreements commit 481,736 shares of FTC Common Stock (5.6% of the
outstanding shares) to be voted in favor of the FTC Merger.

     The agreements further provide that with respect to shares of FTC Common
Stock owned by the directors as individuals or (to the extent of the director's
proportionate voting interest) jointly with other persons (collectively,
"Shares"), the directors will not until the FTC Merger has been consummated or
the FTC Plan of Merger has been terminated:  (1) vote Shares in favor of any
other merger or transaction which would have the effect of a person other than
Keystone or an affiliate acquiring control of FTC or any of its subsidiaries or
(2) sell or otherwise transfer Shares (i) pursuant to any tender offer or
similar proposal made by a person other than Keystone or an affiliate, (ii) to
any person other than Keystone or an affiliate seeking to obtain control of FTC
or any of its subsidiaries or (iii) for the principal purpose of avoiding the
director's obligations under the agreement.  The agreements define "control" as
the ability to (1) direct the voting of 10% or more of the shares eligible to
vote in an election of directors or (2) direct the management and policies of
FTC or a subsidiary.

     The agreements are applicable to the directors only in their capacities as
shareholders and do not affect the exercise of their responsibilities as
directors or officers.  The agreements also do not apply to any shares of FTC
Common Stock held by a director as a trustee or other fiduciary.  No monetary or
other compensation was paid to any FTC director for entering into these
agreements.

     The foregoing is a summary of the material terms of the voting agreements.
The form of these agreements has been filed with the SEC as an exhibit to the
Registration Statement.  Such form is incorporated herein by reference, and the
foregoing summary of the agreements is qualified in its entirety by reference to
such filing.

Opinion of Keystone Financial Advisor

     Keystone retained Danielson Associates Inc. ("Danielson Associates") to
advise the Keystone Board of Directors as to the fairness of the FTC Plan of
Merger to Keystone and its shareholders.  Danielson Associates is regularly
engaged in the valuation of banks, bank holding companies and thrifts in
connection with mergers, acquisitions and other securities transactions and has
extensive knowledge of, and experience with, Pennsylvania banking markets and
banking organizations operating in those markets.  Danielson Associates was
selected by Keystone because of its knowledge of, experience with, and
reputation in the financial services industry.

     At the January 23, 1997 meeting of the Keystone Board of Directors,
Danielson Associates delivered an oral opinion that, in its opinion, as of such
date, the financial terms of the FTC Plan of Merger are "fair" to Keystone and
its shareholders. No limitations were imposed by the Keystone Board of Directors
upon Danielson Associates with respect to the investigations made or procedures
followed by it in arriving at its opinion. Although Danielson Associates
furnished its opinion as to the fairness to Keystone and its shareholders of the
consideration to be paid by Keystone in the FTC Merger, the amount of such
consideration was determined by negotiations between Keystone and FTC in which
Danielson Associates did not participate.

     In arriving at its opinion, Danielson Associates (a) reviewed certain
business and financial information relating to FTC and Keystone, including
annual reports for each of the fiscal years ended December 31, 1994 and 1995 and
[Form 9-Y quarterly report] data from 1989 through 1996, including quarterly
reports for 1996; (b) analyzed certain financial projections of FTC and Keystone
prepared by their managements; (c) discussed the past and current operations,
financial condition and prospects of FTC and Keystone with their senior
executives; (d) analyzed the pro forma impact of the FTC Merger on Keystone's
earnings per share, capitalization and financial ratios; (e) reviewed the
reported prices and trading activity for FTC Common Stock and Keystone Common
Stock and compared them to similar bank holding companies; (f) discussed the
results of recent regulatory examinations of FTC with its senior management; (g)
discussed the strategic objectives of Keystone; (h) reviewed and discussed with
senior management of Keystone selected estimates of the cost savings and revenue
enhancements projected by Keystone for the combined company and compared such
amounts to those estimated in certain precedent transactions; (i) reviewed and
compared the financial terms, to the extent publicly available, with comparable
transactions; (j) reviewed the FTC Plan of Merger and certain related documents;
and (k) considered such other factors as were deemed appropriate.

     Danielson Associates did not perform on its own or obtain any independent
appraisal of assets or liabilities of FTC or Keystone or their respective
subsidiaries nor has Danielson Associates examined any individual loan credit
files of FTC or Keystone.  Further, Danielson Associates did not independently
verify the information provided by FTC or Keystone and assumed the accuracy and
completeness of all such information.  In addition, Danielson Associates has
assumed the FTC Merger will be consummated in accordance with the terms set
forth in the FTC Plan of Merger.

     In arriving at its opinion, Danielson Associates performed a variety of
financial analyses, which it believes must be considered as a whole and that
consideration of portions of such analyses and the factors considered therein,
without considering all factors and analyses, could create an incomplete view of
the analyses and the process underlying its opinion.  The preparation of a
fairness opinion is a complex process involving subjective judgments and is not
necessarily susceptible to partial analysis and summary description.

     In its analyses, Danielson Associates made certain assumptions with respect
to industry performance, business and economic conditions, and other matters,
many of which are beyond Keystone's or FTC's control.  Any estimates contained
in Danielson Associates' analyses are not necessarily indicative of further
results or value, which may be significantly more or less favorable than such
estimates. Estimates of values of companies do not purport to be appraisals or
necessarily reflect the prices at which companies or their securities may
actually be sold.

     Comparable Companies Analyses.  Danielson Associates compared FTC's (a)
tangible capital of 11.35% of assets as of September 30, 1996; (b) 0.31% of
assets not performing as of September 30, 1996; (c) net operating income of
2.36% of average assets for the twelve-month period ending September 30, 1996;
and (d) portfolio mix,

                                      -8-
<PAGE>
 
with the medians for selected bank holding companies that Danielson Associates
deemed comparable.  These medians were (a) tangible capital of 8.65% of assets;
(b) 0.63% of assets not performing; and (c) net operating income of 1.91% of
average assets.  The comparable companies included publicly- traded
Pennsylvania bank holding companies with assets between $1 and $10 billion.

     Danielson Associates also compared Keystone's (a) stock price as of
December 18, 1996 of 14.6 times earnings and 201% of book value, (b) dividend
yield based on stock price as of December 18, 1996 and trailing four quarters
dividends as of September 30, 1996 of 3.92%, (c) tangible capital of 9.44% of
assets as of September 30, 1996, (d) nonperforming assets as of September 30,
1996, 0.86% of total assets and (e) return on average assets during the
trailing four quarters ended September 30, 1996 of 1.36% with the medians for
selected bank and bank holding companies that Danielson Associates deemed to be
comparable to Keystone. The comparable medians were (a) stock price of 14.0
times earnings and 169% of book value, (b) dividend yield of 3.33%, (c)
tangible capital of 8.65% of assets, (d) 0.63% of assets nonperforming and (e)
return on average assets of 1.17%.

     Comparable Transactions Analysis.  Danielson Associates also compared the
consideration to be paid in the FTC Merger to the latest twelve months earnings
and equity capital of FTC with the earnings and capital multiples paid in recent
bank acquisitions.  For this comparison, Danielson Associates used the median of
the multiples of 1996 announced merger and acquisition transactions as of
December 18, 1996 for acquisitions of banks in the Middle Atlantic and Northeast
regions of the country.  At the time Danielson Associates made its analysis, the
consideration to be paid in the FTC Merger equaled 256% of FTC's September 30,
1996 book value and 19.1 times FTC's earnings for the trailing four quarters as
of September 30, 1996.  This compares to median multiples of 238% of book value
and 20.4 times earnings for the most comparable acquisitions.

     Discounted Dividend Analysis.  Danielson Associates performed a discounted
dividend analysis to determine a range of present values per share of FTC Common
Stock assuming FTC continued to operate as a stand-alone entity.  This range was
determined by adding (i) the estimated future dividend stream that FTC could
generate, and (ii) the "terminal value" of FTC Common Stock at the end of year
2001.  The dividend stream and terminal values were discounted to present values
using discount rates which Danielson Associates viewed as appropriate for a
company with FTC's risk characteristics.

     Implied Acquisition Value. As part of its analysis of the acquisition
valuation, Danielson Associates assumed that the net present value of estimated
cost savings and revenue enhancements was added to the stand-alone value of FTC
Common Stock calculated as described above (see "Discounted Dividend Analysis"
above). Based on cost savings and revenue enhancements ranging from $6.4 million
to $8 million (20% to 25% of FTC's non-interest expense base) per year estimated
by the management of Keystone to result from the FTC Merger, Danielson
Associates estimated the implied acquisition value of FTC Common Stock.

     Pro Forma Merger Analysis. Danielson Associates analyzed the financial
impact of the FTC Merger on the holders of Keystone Common Stock, using earnings
estimates for 1997, based on actual 1996 performance, through 2001 and
Keystone's estimates for cost savings and revenue enhancements expected to
result from the FTC Merger. This analysis showed that, after giving effect to
the FTC Merger, before the impact of one-time merger-related charges, current
holders of Keystone Common Stock would realize a decrease in fully diluted
earnings per share in 1997 and a subsequent increase in fully diluted earnings
per share, in each case compared to Keystone on a stand-alone basis. Danielson
Associates also analyzed the changes in return on equity from Keystone on a
stand-alone basis, noting that such return on equity would increase following
the FTC Merger.

     No company or transaction used in any comparisons is identical to FTC and
Keystone.  Accordingly, an analysis of the results of the foregoing is not
purely 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 values of the
company or companies to which they are being compared.

     Compensation of Danielson Associates.  Under the terms of an engagement
agreement dated January 8, 1997, Keystone has paid to Danielson Associates a
fixed fee of $30,000 for furnishing its opinion.  This fee was not

                                      -9-
<PAGE>
 
contingent upon the contents of Danielson Associates' opinion or the conclusions
reached therein.  Keystone has also agreed to reimburse Danielson Associates
for its out-of-pocket expenses incurred in connection with its engagement and
to indemnify Danielson Associates and its officers and employees against
liabilities and expenses resulting from its engagement.

     The summary set forth above does not purport to be a complete description
of the analyses and procedures performed by Danielson Associates in the course
of arriving at its opinions.  The full text of the opinion of Danielson
Associates dated as of February ___, 1997, which sets forth assumptions made
and matters considered, is attached as Appendix I to this Proxy Statement/
Prospectus.  Keystone shareholders are urged to read this opinion in its
entirety.  Danielson Associates' opinion is directed only to the consideration
to be received by FTC shareholders in the Merger and does not constitute a
recommendation to any Keystone shareholder as to how such shareholder should
vote at the Keystone Special Meeting.


Opinion of FTC Financial Advisor

     FTC retained Berwind to act as its financial advisor and to render a
fairness opinion in connection with the FTC Merger.  Berwind rendered its
opinion (the "Opinion") to the Board of Directors of FTC that, based upon and
subject to the various considerations set forth therein, as of the date of this
Joint Proxy Statement/Prospectus, the consideration to be received in the FTC
Merger is fair, from a financial point of view, to the holders of FTC Common
Stock.

     The full text of Berwind's Opinion, which sets forth the assumptions made,
matters considered and limitations of the review undertaken, is attached as
Appendix II to this Joint Proxy Statement/Prospectus, is incorporated herein by
reference, and should be read in its entirety in connection with this Joint
Proxy Statement/Prospectus.  The summary of the Opinion as set forth herein is
qualified in its entirety by reference to the full text of such Opinion attached
as Appendix II to this Joint Proxy Statement/Prospectus.

     Berwind was selected to act as FTC's financial advisor in connection with
the FTC Merger based upon its qualifications, expertise and experience.  Berwind
has knowledge of, and experience with, Pennsylvania and surrounding banking
markets as well as banking organizations operating in those markets and was
selected by FTC because of its knowledge of, experience with, and reputation in
the financial services industry.  Berwind, as part of its investment banking
business, is engaged regularly in the valuation of assets, securities and
companies in connection with various types of asset and security transactions,
including mergers, acquisitions and private placements, and also is engaged in
providing valuations for various other purposes and in the determination of
adequate consideration in such transactions.

     On December 19, 1996 FTC's Board of Directors approved and its officers
executed the FTC Plan of Merger.  In connection with and as a condition
precedent to the FTC Merger, Berwind delivered its Opinion to FTC stating that,
as of the date of the Opinion, the consideration to be received in the FTC
Merger was fair to the shareholders of FTC from a financial point of view.  The
full text of the Opinion which sets forth assumptions made, matters considered
and limits on the review undertaken is attached as Appendix II to this Joint
Proxy Statement/Prospectus.  No limitations were imposed by FTC's Board of
Directors upon Berwind with respect to the investigations made or procedures
followed by Berwind in rendering the Opinion.

     In rendering its Opinion, Berwind:  (i) reviewed the historical financial
performances, current financial positions and general prospects of FTC and
Keystone; (ii) reviewed the FTC Plan of Merger; (iii) reviewed and analyzed the
stock market performance of FTC and Keystone; (iv) studied and analyzed the
consolidated financial and operating data of FTC and Keystone; (v) considered
the terms and conditions of the proposed FTC Merger as compared with the terms
and conditions of comparable bank and bank holding company mergers and
acquisitions; (vi) met and/or communicated with certain members of FTC's and
Keystone's senior management to discuss their respective operations, historical
financial statements, and future prospects; (vii) reviewed this Joint Proxy
Statement/Prospectus, and (viii) conducted such other financial analyses,
studies and investigations as Berwind deemed appropriate.

                                      -10-

     In delivering its Opinion, Berwind assumed that in the course of obtaining
the necessary regulatory and governmental approvals for the FTC Merger, no
restriction will be imposed that would have a material adverse effect on the
contemplated benefits of the FTC Merger.  Berwind also assumed that there would
not occur any change in applicable law or regulation that would cause a material
adverse change in the prospects or operations of Keystone after the FTC Merger.

     Berwind relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by and
discussed with it for purposes of its Opinion.  With respect to FTC's financial
projections reviewed by Berwind in rendering its Opinion, Berwind assumed that
such financial projections were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the management of FTC as to the
future financial performance of FTC.  Berwind did not make an independent
evaluation or appraisal of the assets (including loans) or liabilities of FTC or
Keystone nor was it furnished with any such appraisal.  Berwind also did not
independently verify and has relied on and assumed that all allowances for loan
and lease losses set forth in the balance sheets of FTC and Keystone were
adequate and complied fully with applicable law, regulatory policy and sound
banking practice as of the date of such financial statements.

     The following is a summary of selected analyses prepared by Berwind in
connection with the delivery of its Opinion:

     Comparable Companies and Comparable Acquisition Transaction Analyses.
Berwind compared selected financial and operating data for FTC with those of a
peer group of selected banks and bank holding companies with assets between $1
billion and $2 billion, as of the most recent financial period publicly
available, located in Pennsylvania, Maryland, Ohio and West Virginia.  Financial
data and operating ratios compared in the analysis of the FTC peer group
included but were not limited to:  return on average equity, shareholders'
equity to assets ratio and certain asset quality ratios.

     Berwind also compared selected financial, operating and stock market data
for Keystone with those of a peer group of selected commercial banks with assets
between $3.5 billion and $7 billion, as of the most recent period publicly
available, located in Pennsylvania, Maryland, New Jersey, Ohio and West
Virginia.  Financial, operating and stock market data, ratios and multiples
compared in the analysis of the Keystone peer group included but were not
limited to:  return on average assets, return on average equity, shareholders'
equity to asset ratios, certain asset quality ratios, price to book value, price
to tangible book value, price to earnings (latest twelve months) and dividend
yield.

     Berwind also compared the multiples of book value, tangible book value and
latest twelve months' earnings of the FTC Merger with the multiples paid in
recent acquisitions of banks and bank holding companies that Berwind deemed
comparable.  The transactions deemed comparable by Berwind included both
interstate and intrastate acquisitions announced during the twelve month period
ended as of the date of the Opinion, in which the selling institution's assets
were between $750 million and $3 billion.  No company or transaction, however,
used in this analysis is identical to FTC, Keystone or the FTC Merger.
Accordingly, an analysis of the result 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 would affect the public trading values of the companies or company to which
they are being compared.

     Discounted Dividend Analyses.  Using discounted dividend analyses, Berwind
estimated the present value of the future dividend streams that FTC could
produce over a five-year period under various earnings growth assumptions.
Berwind also estimated the terminal value for FTC's Common Stock after the five-
year period by applying a range of earnings multiples to FTC's terminal year
earnings.  The range of multiples used reflected a variety of scenarios
regarding the growth and profitability prospects of FTC.  The dividend streams
and terminal values were then discounted to present value using discount rates,
reflecting different assumptions regarding the rates of return expected by
holders or prospective buyers of FTC's Common Stock.

                                      -11-
<PAGE>
 
     Pro Forma Contribution Analysis.  Berwind analyzed the changes in the
amount of earnings, book value and dividends represented by one share of FTC
Common Stock prior to the FTC Merger and 1.65 shares of Keystone Common Stock
after the FTC Merger.  The analysis considered, among other things, the changes
that the FTC Merger would cause to FTC's earnings per share, book value per
share, tangible book value per share and indicated dividends.  In reviewing the
pro forma combined earnings, equity and assets of Keystone based on the FTC
Merger with FTC, Berwind analyzed the contribution that FTC would have made to
the combined company's earnings, equity and assets as of and for the period
ended December 31, 1996. Berwind also reviewed the percentage ownership that
FTC shareholders would hold in the combined company.

     In connection with rendering its Opinion, Berwind performed a variety of
financial analyses.  Although the evaluation of the fairness, from a financial
point of view, of the consideration to be paid in the FTC Merger was to some
extent a subjective one based on the experience and judgment of Berwind and not
merely the result of mathematical analyses of financial data, Berwind
principally relied on the previously discussed financial valuation methodologies
in its determinations.  Berwind believes its analyses must be considered as a
whole and that selecting portions of such analyses and factors considered by
Berwind without considering all such analyses and factors could create an
incomplete view of the process underlying Berwind's Opinion.  In its analysis,
Berwind made numerous assumptions with respect to business, market, monetary and
economic conditions, industry performance and other matters, many of which are
beyond FTC's and Keystone's control.  Any estimates contained in Berwind's
analyses are not necessarily indicative of future results or values, which may
be significantly more or less favorable than such estimates.

     In reaching its opinion as to fairness, none of the analyses performed by
Berwind was assigned a greater or lesser weighting by Berwind than any other
analysis.  As a result of its consideration of the aggregate of all factors
present and analyses performed, Berwind reached the conclusion, and opined, that
the consideration to be received in the FTC Merger as set forth in the FTC Plan
of Merger is fair from a financial point of view to FTC and its shareholders.

     Berwind's Opinion was based solely upon the information available to it and
the economic, market and other circumstances as they existed as of the date its
Opinion was delivered; events occurring after the date of its Opinion could
materially affect the assumptions used in preparing its Opinion.  Berwind has
not undertaken to reaffirm and revise its Opinion or otherwise comment upon any
events occurring after the date thereof.

     Pursuant to the terms of its engagement, FTC has paid Berwind $250,000 for
acting as financial advisor in connection with the FTC Merger including
delivering its Opinion.  In addition, FTC has also agreed to pay Berwind
$1,550,000 upon the consummation of the FTC Merger and to reimburse Berwind for
its reasonable out-of-pocket expenses.  Whether or not the FTC Merger is
consummated, FTC has also agreed to indemnify Berwind and certain related
persons against certain liabilities relating to or arising out of its
engagement.

     The full text of the Opinion of Berwind dated as of the date of this Joint
Proxy Statement/Prospectus, which sets forth assumptions made and matters
considered, is attached hereto as Appendix II.  FTC's shareholders are urged to
read the Opinion in its entirety.  Berwind's Opinion is directed only to the
consideration to be received by FTC's shareholders in the FTC Merger and does
not constitute a recommendation to any holder of FTC Common Stock as to how
such holder should vote at the FTC Special Meeting.

     THE FOREGOING PROVIDES ONLY A SUMMARY OF THE OPINION OF BERWIND AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THAT OPINION, WHICH
IS SET FORTH IN APPENDIX II TO THIS JOINT PROXY STATEMENT/PROSPECTUS.


Conversion of FTC Shares

     Exchange Ratio.  On the effective date of the FTC Merger, each outstanding
share of FTC Common Stock will be converted into the right to receive 1.65
shares of Keystone Common Stock, with cash to be paid in lieu of

                                      -12-
<PAGE>
 
any fractional share.  On February ___, 1997, the closing sale price for
Keystone Common Stock reported on the NASDAQ National Market System was $_____.

     Surrender of Certificates.  As promptly as practicable after the effective
date of the FTC Merger, Keystone will send to each shareholder of record of FTC
immediately prior to the FTC Merger a letter of transmittal containing
instructions on how to effect the exchange of FTC Common Stock certificates for
certificates representing the shares of Keystone Common Stock into which their
shares have been converted.  FTC shareholders should not send in their
certificates until they receive such written instructions.  However,
certificates should be surrendered promptly after instructions to do so are
received.

     Any dividends declared on Keystone Common Stock after the effective date of
the FTC Merger will apply to all whole shares of Keystone Common Stock into
which shares of FTC Common Stock have been converted in the FTC Merger.
However, no former FTC shareholder will be entitled to receive any such dividend
until such shareholder's FTC Common Stock certificates have been surrendered for
exchange as provided in the letter of transmittal.  Upon such surrender, the
shareholder will be entitled to receive all such dividends payable on the whole
shares of Keystone Common Stock represented by the surrendered certificate or
certificates (without interest thereon and less the amount of taxes, if any,
which may have been imposed or paid thereon).

     Payment for Fractional Shares.  No fractional shares of Keystone Common
Stock will be issued in connection with the FTC Merger.  Instead, each FTC
shareholder who surrenders for exchange FTC Common Stock certificates
representing a fraction of a share of Keystone Common Stock will be entitled to
receive, in addition to a certificate for the whole shares of Keystone Common
Stock represented by the surrendered certificates, cash in an amount equal to
such fractional part of a share multiplied by the value of $26.50 for one whole
share of Keystone Common Stock.

     Unexchanged Certificates.  On the effective date of the FTC Merger, the
stock transfer books of FTC will be closed, and no further transfers of FTC
Common Stock will be made or recognized.  Certificates for FTC Common Stock not
surrendered for exchange will entitle the holder only to receive, upon surrender
as provided in the letter of transmittal, a certificate for the whole shares of
Keystone Common Stock represented by such certificates, plus payment of any
amount for a fractional share or dividends to which such holder is entitled as
outlined above.

     If the FTC Merger becomes effective and any former FTC shareholder does not
surrender his or her FTC Common Stock certificates for exchange on or before the
second anniversary of the effective date, Keystone, at its option, may at any
time thereafter sell such shareholder's Keystone Common Stock without notice to
the shareholder.  After any such sale, the sole right of such shareholder shall
be to receive, upon surrender of the shareholder's FTC Common Stock
certificates, the net proceeds of the sale (without interest and less the amount
of any taxes which may have been imposed or paid thereon).

     Keystone Shareholder Rights Plan.  If no Distribution Date under Keystone's
shareholder rights plan (see "Comparison of Keystone Common Stock and FTC Common
Stock--Keystone Shareholder Rights Plan") shall have occurred prior to the
effective date of the FTC Merger, then each share of Keystone Common Stock
issued in the FTC Merger shall also evidence one Right under Keystone's
shareholder rights plan.  If the Distribution Date shall have occurred, then it
is a condition to the FTC Merger that Keystone take one of the actions set forth
under "Conditions to the FTC Merger" below.

     Adjustment of Exchange Ratio.  The FTC Plan of Merger contains provisions
for the proportionate adjustment of the exchange ratio in the event of a stock
dividend, stock split, reclassification or similar event involving the Keystone
Common Stock or the FTC Common Stock which occurs prior to the FTC Merger.

Tax Consequences to FTC Shareholders

     Federal Income Tax.  The FTC Plan of Merger requires as a condition to the
FTC Merger that each party receive a written opinion of counsel or of
independent public accountants that for purposes of federal income tax:

          (1)  The FTC Merger will constitute a reorganization within the
     meaning of Section 368(a)(1)(A) of the Internal Revenue Code of 1986, as
     amended (the "Code"), and Keystone and FTC will each be a "party to a
     reorganization" within the meaning of Section 368(b) of the Code;

          (2)  No gain or loss will be recognized by Keystone or FTC as a result
     of the FTC Merger;

          (3)  Except for cash received in lieu of fractional shares, no gain or
     loss will be recognized by holders of FTC Common Stock on the exchange of
     their shares for shares of Keystone Common Stock;

          (4)  The basis of the shares of Keystone Common Stock to be received
     by the shareholders of FTC will be the same as the basis of the shares of
     FTC Common Stock exchanged therefor; and

          (5)  The holding period of the shares of Keystone Common Stock
     received by the shareholders of FTC will include the period during which
     the FTC Common Stock exchanged therefor was held by the FTC shareholder,
     provided that the FTC Common Stock was held as a capital asset at the time
     of the exchange.

     No gain or loss for federal income tax purposes will be recognized by
shareholders of FTC on the exchange of their shares for whole shares of Keystone
Common Stock.  However, gain or loss will be recognized by FTC shareholders upon
the receipt of cash in payment for a fractional share.  To compute the amount,
if any, of such gain or loss, the cost or other basis of the FTC Common Stock
exchanged must be allocated proportionately to the total number of shares of
Keystone Common Stock received, including any fractional share interest.  Gain
or loss will be recognized measured by the difference between the cash received
and the basis of the fractional share interest as so allocated.  Under Section
302(a) of the Code, any such gain or loss will generally be entitled to capital
gain or loss treatment if the FTC Common Stock was a capital asset in the hands
of the shareholder.

     If any shares of Keystone Common Stock received in the FTC Merger are
subsequently sold, gain or loss on the sale should be computed by allocating the
cost or other basis of the FTC Common Stock exchanged in the FTC Merger to the
shares sold in the manner described in the preceding paragraph.  The holding
period for the shares of Keystone Common Stock received in the FTC Merger will
include the holding period for the shares of FTC Common Stock exchanged in
determining, for example, whether any such gain or loss is a long-term or short-
term capital gain or loss.

     Pennsylvania Personal Income Tax.  No gain or loss for Pennsylvania
personal income tax purposes will be recognized by shareholders of FTC who are
subject to that tax on the receipt by them of whole shares of Keystone Common
Stock in exchange for their FTC Common Stock.  For Pennsylvania personal income
tax purposes, the tax basis for the Keystone Common Stock received by FTC
shareholders in the FTC Merger (including any fractional share interests to
which they are entitled) will be the same as the basis of the FTC Common Stock
exchanged.  Cash received in lieu of a fractional share of Keystone Common Stock
will be treated and taxed as if the fractional share had actually been received
by the FTC shareholder and then immediately sold by the shareholder to Keystone
for the cash received.

     The foregoing is intended only as a summary of certain federal income tax
and Pennsylvania personal income tax consequences of the FTC Merger under
existing law and regulations, as presently interpreted by judicial decisions and
administrative rulings, all of which are subject to change without notice, and
any such change might be retroactively applied to the FTC Merger.  Among other
things, the summary does not address state income tax consequences in states
other than Pennsylvania, local taxes, or the federal or state income tax
considerations that may affect the treatment of a shareholder who acquired FTC
Common Stock pursuant to an employee stock option.  Accordingly, it is
recommended that FTC shareholders consult their own tax advisors with

                                      -14-
<PAGE>
 
specific reference to their own tax situations and potential changes in the
applicable law as to all federal, state and local tax matters in connection with
the FTC Merger.


Keystone Board of Directors Following the FTC Merger

     At the time the FTC Merger becomes effective, Ray L. Wolfe, currently
Chairman and Chief Executive Officer of FTC, will become Chairman of the Board
of Keystone and will become a member of the Board of Directors of Keystone with
a term expiring at Keystone's Annual Meeting in the year 2000.  In addition, two
other directors of FTC, each to be designated by FTC subject to the approval of
Keystone, will become members of the Board of Directors of Keystone to serve for
terms expiring at Keystone's Annual Meetings in 1998 and 1999, respectively.  If
prior to the FTC Merger Mr. Wolfe or one of the other two FTC directors becomes
unable or declines to serve as a director of Keystone, FTC shall be entitled to
designate a substitute director acceptable to Keystone.

     Keystone's Board of Directors presently consists of 17 directors, divided
into three classes.  See "Comparison of Keystone Common Stock and FTC Common
Stock--Board of Directors--Classified Boards."  Six Keystone directors will be
elected at Keystone's 1997 Annual Meeting to serve for terms expiring in 2000.
Of the remaining directors, the terms of five expire at the 1998 Annual Meeting
and six at the 1999 Annual Meeting.


Interests of Certain Persons in the Transaction

     Ray L. Wolfe Employment Agreement.  In connection with the FTC Plan of
Merger, Keystone has entered into an Employment Agreement with Ray L. Wolfe,
Chairman and Chief Executive Officer of FTC.  The Employment Agreement, which
would become effective only on consummation of the FTC Merger, provides for Mr.
Wolfe's employment by Keystone for a period of three years following the
effective date of the FTC Merger at an all inclusive annual rate of compensation
of $350,000, plus participation in such benefit and qualified retirement plans
as are generally available to Keystone employees.  For 1996, Mr. Wolfe's
aggregate compensation from FTC and its subsidiaries was $413,757, plus stock
option grants for 3,682 shares of FTC Common Stock. From the date of the FTC
Merger until Keystone's annual meeting of shareholders in 1998, Mr. Wolfe would
serve as Chairman of the Board of Keystone.  Thereafter during the three-year
period, Mr. Wolfe would serve in such senior executive capacities as are
mutually agreed from time to time between Mr. Wolfe and Keystone's chief
executive officer.  From the end of the three-year period until Mr. Wolfe's 65th
birthday on August 15, 2003, Mr. Wolfe would be employed by Keystone as a
consultant at an annual rate of compensation of $177,000, plus participation in
Keystone's regular medical care benefits plan.  The Employment Agreement and the
compensation and benefits to be provided to Mr. Wolfe thereunder may not be
terminated by Keystone except upon Mr. Wolfe's death, total and permanent
disability or substantial incapacity for a period exceeding six months or a
breach by Mr. Wolfe of the nondisclosure and noncompetition provisions of the
Agreement.  The agreement prohibits Mr. Wolfe from disclosing Keystone
confidential information at any time or, during the period ending two years
after termination of his employment, from engaging directly or indirectly in any
business which is in competition with Keystone or any of its subsidiaries in the
areas of commercial banking, mortgage banking, leasing or the taking of deposits
and which is located or operating in any county in which Keystone or a
subsidiary has offices or any contiguous county.  In the event of a change of
control of Keystone, as defined in the agreement, Mr. Wolfe may elect to be paid
the balance of the cash compensation for the term of the agreement in a single
lump sum.  In this event, both parties would be released from any further
obligations under the agreement, except that Mr. Wolfe would remain subject to
the agreement's nondisclosure and noncompetition provisions.

     FTC Directors' and Officers' Indemnification.  Keystone has agreed that, to
the extent permitted by law, all rights to indemnification and limitation of
liability existing in favor of the current or former directors or officers of
FTC and its subsidiaries, as provided in their respective charters or bylaws,
shall survive the FTC Merger and that following the FTC Merger, to the extent
permitted by law, Keystone and the former subsidiaries of FTC shall honor such
obligations with respect to events, acts or omissions occurring prior to the FTC
Merger.  Any amendment after the FTC Merger to the limitation of liability or
indemnification provisions of an FTC subsidiary's

                                      -15-
<PAGE>
 
charter or bylaws will not apply to events occurring prior to the FTC Merger.
The bylaws of FTC provide that a director of FTC generally shall not be
personally liable for monetary damages for any act or omission as a director
unless the act or omission constitutes a breach of duty amounting to self-
dealing, willful misconduct or recklessness. The articles of incorporation of
FTC generally require FTC to indemnify its directors and officers against any
and all expenses, liabilities or other matters for which indemnification is
permitted by applicable law. Pennsylvania law generally permits a Pennsylvania
corporation such as FTC to indemnify its directors and officers against
expenses, liabilities and other matters, both as to action in their official
capacities and as to action in another capacity while holding that office,
except where the act or omission giving rise to the claim for indemnification is
determined by a court to have constituted willful misconduct or recklessness.
The bylaws of Keystone and its subsidiaries contain similar provisions regarding
limitation of liability and indemnification of directors and officers.

     Employee Benefit Plans.  The FTC Plan of Merger provides that following the
FTC Merger, employees of FTCs subsidiaries and employees of FTC who become
Keystone employees shall be entitled to participate in generally applicable
Keystone employee benefit plans on the same basis as other similarly situated
employees of Keystone and its subsidiaries.  Prior service of such employees
with FTC and its subsidiaries shall be counted in determining eligibility to
participate in such plans and for purposes of vesting of benefits, but not for
purposes of benefit accrual.


Warrant Agreement

     In connection with the FTC Plan of Merger, Keystone and FTC have entered
into an Investment Agreement, and FTC has issued to Keystone a Warrant
thereunder (collectively, the "Warrant Agreement") entitling Keystone to
purchase up to approximately 19.9% (after exercise) of FTC's outstanding Common
Stock upon the occurrence of certain events described below.  The Warrant
Agreement covers 2,113,706 shares of FTC Common Stock at an exercise price of
$43.725 per share.

     The Warrant Agreement is designed to compensate Keystone for its risks,
costs and expenses and the commitment of resources associated with the FTC Plan
of Merger in the event the FTC Merger is not consummated due to an attempt by a
third person to gain control of FTC.  See also "Expenses" below.  Keystone may
not exercise or sell its Warrant except upon (i) a willful breach by FTC of the
FTC Plan of Merger, (ii) the failure of FTC's shareholders to approve the FTC
Plan of Merger after the announcement by a third person of a proposal to acquire
10% or more of the FTC Common Stock, to acquire, merge or consolidate with FTC
or any of its subsidiaries or to acquire substantially all of the assets of FTC
or any of its subsidiaries, (iii) the acquisition by a third person of
beneficial ownership of 1% or more of the outstanding FTC Common Stock if after
such acquisition such person would beneficially own 10% or more of the FTC
Common Stock, (iv) the commencement by a third person of a tender offer or
exchange offer which would result in beneficial ownership of 10% or more of the
FTC Common Stock, or (v) the entry by FTC or any of its subsidiaries into an
agreement or understanding with a third person for the third person to acquire,
merge or consolidate with FTC or any of its subsidiaries or to acquire
substantially all of the assets of FTC or any of its subsidiaries (each of the
foregoing is hereafter referred to as a "Warrant Event").  No Warrant Event has
occurred as of the date of this Joint Proxy Statement/Prospectus, and neither
Keystone nor FTC is aware that any Warrant Event is contemplated by any third
person.  The Warrant Agreement may discourage third persons from making
competing offers to acquire FTC and is intended to increase the likelihood that
the FTC Merger will be consummated in accordance with the terms set forth in the
FTC Plan of Merger.

     If a Warrant Event occurs, Keystone may exercise the Warrant in whole or in
part or may sell or transfer all or part of the Warrant to other persons.  Under
federal banking law, exercise of the Warrant by Keystone for more than 5% of the
outstanding FTC Common Stock would require approval of the Board of Governors of
the Federal Reserve System ("Federal Reserve Board").  Any sale of the Warrant
or of shares of FTC Common Stock purchased thereunder would be subject to a
right of first refusal by FTC unless sold in a public offering registered under
the Securities Act.  FTC agrees in the Warrant Agreement to effect such
registration if requested.

                                      -16-
<PAGE>
 
     Keystone may require FTC to redeem the Warrant or any shares of FTC Common
Stock purchased thereunder if (i) a third person acquires beneficial ownership
of 50% or more of the outstanding FTC Common Stock or (ii) a third person
acquires, merges or consolidates with FTC or any of its subsidiaries or acquires
substantially all of the assets of FTC or any of its subsidiaries (each of the
foregoing is hereafter referred to as a "Redemption Event").  In general, the
per share redemption price for the Warrant would be the higher of 10% of the
exercise price or a per share price based on the difference between the exercise
price and the highest price paid or agreed to be paid by the third person in
connection with the Redemption Event.  The per share redemption price for shares
of FTC Common Stock purchased under the Warrant would generally be the higher of
110% of the exercise price or the highest price paid or agreed to be paid by the
third person in connection with the Redemption Event.

     The Warrant Agreement also contains provisions giving FTC the right to
repurchase shares of FTC Common Stock issued under the Warrant in certain
limited circumstances and provisions for issuance of a substitute Warrant to
purchase shares of the surviving or acquiring company in the event of a merger
or other acquisition of FTC or any of its subsidiaries.

     The foregoing description is intended only as a summary of the material
provisions of the Warrant Agreement and does not purport to be complete.  It is
qualified in its entirety by reference to the Warrant Agreement, which has been
filed with the SEC as an exhibit to the Registration Statement.  The Warrant
Agreement is incorporated in this Joint Proxy Statement/Prospectus by reference
to such filing.


Inconsistent Activities

     FTC has agreed in the FTC Plan of Merger that unless and until the FTC
Merger has been consummated or the FTC Plan of Merger has been terminated in
accordance with its terms, FTC will not (i) solicit or encourage any proposals
by a third person to acquire more than 1% of the FTC Common Stock, any stock of
any FTC subsidiary or any significant portion of FTC's or any FTC subsidiary's
assets (whether by tender offer, merger, purchase of assets or otherwise), (ii)
afford a third party which may be considering any such transaction access to
FTC's or any FTC subsidiary's properties, books or records except as required by
law, (iii) enter into any discussions, negotiations, agreement or understanding
for any such transaction or (iv) authorize or permit any of its directors,
officers, employees or agents to do any of the foregoing.  Notwithstanding the
foregoing, FTC may take an action referred to in clause (ii) or (iii) of the
previous sentence (or permit its directors, officers, employees or agents to do
so) if FTC's Board of Directors, after consulting with counsel, determines that
such actions should be taken or permitted in the exercise of its fiduciary
duties.  If FTC becomes aware of any offer or proposed offer to acquire any
shares of FTC or any FTC subsidiary or any significant portion of FTC's or any
FTC subsidiary's assets, or of any other matter which could adversely affect the
FTC Merger, FTC is required to give immediate notice thereof to Keystone.


Conduct of FTC's Business Pending the FTC Merger

     FTC has agreed in the FTC Plan of Merger that pending consummation of the
FTC Merger, except as consented to by Keystone, FTC and its subsidiaries will
conduct their businesses only in the ordinary course and will not, among other
things, (i) issue, purchase or otherwise dispose of or acquire any shares of
their capital stock or grant any options or other rights to acquire such stock,
except pursuant to the Warrant Agreement, FTC's employee stock option plan or
existing employee and director stock options; (ii) make certain changes in the
compensation or benefits payable to employees or enter into employment
contracts; (iii) merge or consolidate with, or acquire control over, any other
corporation, bank or other organization or acquire or dispose of any material
assets outside the ordinary course of business; (iv) make capital expenditures
or lease assets in excess of certain limits; or (v) make material changes to
their lending or investment policies.

                                      -17-
<PAGE>
 
FTC Dividend Limitation

     FTC has agreed in the FTC Plan of Merger that pending the FTC Merger it
will not increase the rate of dividends on the FTC Common Stock to exceed $.25
per share in the quarters ending March 31 and June 30, 1997 or $.27 per share in
any calendar quarter thereafter.  During the quarter ended December 31, 1996,
dividends on the FTC Common Stock were paid at the rate of $.25 per share.


Conditions to the FTC Merger

     In addition to shareholder approval, the FTC Merger is contingent upon the
satisfaction of a number of other conditions, including (i) approval of the FTC
Merger by the Federal Reserve Board, the Pennsylvania Department of Banking and
the Maryland Bank Commissioner without conditions deemed unduly burdensome by
Keystone, (ii) the absence of any suit by the United States under the antitrust
laws to prohibit the FTC Merger filed within the 30 days following Federal
Reserve Board approval, (iii) receipt of the tax opinion described above (see
"Tax Consequences") and (iv) the absence of any judicial or administrative order
prohibiting or adversely affecting the FTC Merger or any pending or threatened
litigation or administrative proceeding challenging the FTC Merger. Keystone's
obligation to consummate the FTC Merger is subject to the following additional
conditions:  (i) qualification of the FTC Merger for pooling-of-interests
accounting treatment and, if requested by Keystone, receipt of a letter from
Keystone's independent auditors to that effect and (ii) receipt of the
agreements of FTC affiliates described below under "Restrictions on Resales by
FTC Affiliates."  In addition, unless waived, each party's obligation to
consummate the FTC Merger is subject to the performance by the other party of
its obligations under the FTC Plan of Merger, the accuracy of the
representations and warranties of the other party contained therein and the
receipt of certain certificates and opinions from the other party and its
counsel.  If the Distribution Date under Keystone's shareholder rights plan (see
"Comparison of Keystone Common Stock and FTC Common Stock--Keystone Shareholder
Rights Plan") shall have occurred, then either (i) all Rights outstanding under
the plan (other than those which have become void) shall have been exchanged for
Keystone Common Stock and the exchange ratio for converting FTC Common Stock
into Keystone Common Stock in the FTC Merger shall have been proportionately
adjusted as provided in the FTC Plan of Merger, (ii) all Rights outstanding
under the plan shall have been redeemed or (iii) Keystone shall have made
provision for the issuance of equivalent rights to the holders of FTC Common
Stock upon consummation of the FTC Merger.  The FTC Merger is independent of the
FFWM Merger and is not in any way contingent upon the consummation of the FFWM
Merger.


Representations and Warranties

     The representations and warranties of Keystone and FTC contained in the FTC
Plan of Merger relate, among other things, to the organization and good standing
of Keystone, FTC and their subsidiaries; the capitalization of Keystone and FTC
and ownership of their subsidiaries; the authorization by Keystone and FTC of
the FTC Plan of Merger and the Warrant Agreement and the absence of conflict
with laws or other agreements; the accuracy and completeness of the financial
statements and other information furnished to the other party; the absence of
material adverse changes since December 31, 1995; the absence of undisclosed
litigation; compliance with laws; the absence of certain potential environmental
liabilities; and the accuracy of this Joint Proxy Statement/Prospectus and of
Keystone's Registration Statement of which it is a part.  Additional
representations and warranties by FTC concern payment of taxes; title to
properties; and the absence of undisclosed equity investments, employment
contracts, employee benefit plans or material contracts.  None of the
representations and warranties contained in the FTC Plan of Merger will survive
the consummation of the FTC Merger.


Amendment, Waiver and Termination

     Notwithstanding prior shareholder approval, the FTC Plan of Merger may
be amended in any respect by written agreement between the parties, except
that after FTC shareholder approval no amendment may change the rate of
exchange of FTC Common Stock for Keystone Common Stock in the FTC Merger or
change the form of

                                      -18-
<PAGE>
 
such consideration.  Keystone or FTC may also (i) extend the time for
performance of any of the obligations of the other; (ii) waive any inaccuracies
in the representations and warranties of the other; (iii) waive compliance by
the other with any of its obligations under the FTC Plan of Merger; and (iv)
waive any condition precedent to its obligations under the FTC Plan of Merger
other than approval by the shareholders of FTC and Keystone of the FTC Plan of
Merger, governmental regulatory approvals required to consummate the FTC Merger,
securities registration requirements incident to the issuance of Keystone Common
Stock in the FTC Merger and the receipt of the tax opinions described above.

     Notwithstanding prior shareholder approval, the FTC Plan of Merger may be
terminated without liability of either party at any time prior to effectiveness
of the FTC Merger (i) by mutual consent of Keystone and FTC or (ii) by either
party in the event of (a) a material breach by the other party of a
representation and warranty or covenant which has not been cured within 30 days
after notice to the breaching party, (b) failure of the shareholders of Keystone
or FTC to approve the FTC Plan of Merger at the appropriate Special Meeting, (c)
a final judicial or regulatory determination denying any regulatory approval
required for the FTC Merger or imposing conditions or requirements which
Keystone reasonably determines to be materially adverse to its interests, or (d)
failure to satisfy prior to December 31, 1997 any condition to its obligations
to consummate the FTC Merger, if such failure occurs despite the good faith
effort of the terminating party to perform all covenants and satisfy all
conditions required of it.


Absence of Dissenters' Rights of Keystone or FTC Shareholders

     Under Section 1571(b)(1)(ii) of the Pennsylvania Business Corporation Law,
shareholders of Keystone and FTC do not have statutory dissenters' rights with
respect to either the FTC Merger or the FFWM Merger since both Keystone Common
Stock and FTC Common Stock is held of record by more than 2,000 shareholders.


Restrictions on Resales by FTC Affiliates

     The shares of Keystone Common Stock issuable in the FTC Merger have been
registered under the Securities Act, and such shares will generally be freely
tradable by the FTC shareholders who receive Keystone Common Stock as a result
of the FTC Merger.  However, this registration does not cover resales by FTC
shareholders who may be deemed to control or be under common control with FTC
and who therefore may be deemed "affiliates" of FTC as that term is defined in
Rule 145 under the Securities Act.  Such affiliates may not sell their shares of
Keystone Common Stock acquired in the FTC Merger except pursuant to:  (i) an
effective Registration Statement under the Securities Act covering the shares to
be sold; (ii) the conditions contemplated by Rules 144 and 145 under the
Securities Act; or (iii) another applicable exemption from the registration
requirements of the Securities Act.  The management of FTC will notify those
persons whom it believes may be such affiliates.

     The FTC Plan of Merger requires as a condition to the FTC Merger that each
such FTC affiliate enter into an agreement not to sell the shares of Keystone
Common Stock acquired in the FTC Merger except in accordance with the
requirements of the Securities Act and the regulations thereunder.  In order to
preserve the intended accounting treatment of the FTC Merger as a pooling of
interests, the agreement also prohibits FTC affiliates from selling any shares
of Keystone Common Stock or FTC Common Stock from the 30th day prior to the FTC
Merger until Keystone's financial results covering at least 30 days of post-FTC
Merger combined operations have been published.


Effect of Certain Transactions Involving Keystone

     The FTC Plan of Merger provides that Keystone may not enter into an
agreement for a merger, consolidation or share exchange in which it will not be
the surviving or resulting corporation unless the surviving or resulting
corporation shall have agreed in writing to be bound by the terms of the FTC
Plan of Merger and the

                                      -19-
<PAGE>
 
Warrant Agreement. If under the terms of any such transaction the outstanding
Keystone Common Stock is converted into or exchanged for other securities of any
person, cash or other property, the FTC Plan of Merger shall be appropriately
amended so that FTC shareholders will receive in the FTC Merger, for each share
of FTC Common Stock held, the consideration paid in such transaction for shares
of Keystone Common Stock multiplied by the exchange ratio under the FTC Plan of
Merger (appropriately adjusted to reflect such event). As indicated above, it is
a condition to the Merger that the parties receive the tax opinion described
under "Tax Consequences" above. While this condition will not prevent Keystone
from entering into any such transaction, FTC is not required to amend or waive
this condition. Keystone must obtain the consent of FTC, which shall not
unreasonably be withheld, before entering into an agreement for any such
transaction which would result in Keystone's acquisition of a business in which,
excluding the impact of the FTC Merger and the FFWM Merger, (1) Keystone's
investment or proportionate share of the assets would exceed 20% of Keystone's
consolidated assets at the end of the most recent year, (2) Keystone's equity in
the income would exceed 20% of Keystone's consolidated net income for the most
recent year or (3) the number of shares of Keystone Common Stock to be issued in
the acquisition would exceed 20% of the shares outstanding at initiation of the
acquisition.

     As of the date of this Joint Proxy Statement/Prospectus, Keystone does not
contemplate entering into any transaction of the type described above, and
Keystone is not aware that any such transaction is contemplated by any third
person.


Effect on FTC Employee and Director Stock Options

     Stock options for [114,115] shares of FTC Common Stock (the "FTC options")
are presently outstanding under FTC's 1992 Stock Option Plan and its 1994 Non-
Employee Director Stock Option Plan at option prices equal to the fair market
value of such shares on the dates the options were granted.  Under the FTC Plan
of Merger, FTC may amend the agreements relating to the FTC options to provide
that when the FTC Merger becomes effective (i) unexercised FTC options will be
converted into options for the number of shares of Keystone Common Stock the
optionee would have received under the FTC Plan of Merger had the FTC option
been exercised prior to the FTC Merger and (ii) the option price per share will
be proportionately adjusted.  Keystone has also agreed to register under the
Securities Act the shares of Keystone Common Stock issuable upon exercise of the
amended FTC options by filing a registration statement with the SEC not later
than 30 days after its first Annual Report on Form 10-K after the FTC Merger is
filed with the SEC.  Holders of FTC options may be prohibited under the
Securities Act from exercising such options after the FTC Merger becomes
effective until this registration statement is filed and becomes effective even
if, under the terms of the FTC option, such option would expire prior to the
time of such filing.


Effect on FTC's Dividend Reinvestment Plan

     FTC's Dividend Reinvestment Plan [has been] [will be] terminated following
reinvestment of the dividend payable                    , 1997.  Following the
                                     -------------------
FTC Merger, shareholders will be able to participate in a Dividend Reinvestment
Plan offered by Keystone.


Expenses

     Keystone and FTC will each pay its own expenses incurred in connection with
the FTC Plan of Merger, except that (1) each party will pay the cost of printing
and mailing this Joint Proxy Statement/Prospectus and other proxy materials to
its own shareholders, (2) each party will pay one-half of the cost of the tax
opinion referred to above and (3) Keystone will pay the costs of printing and
filing the Registration Statement and any materials required by state securities
laws and the costs of preparing and filing the applications for the regulatory
approvals required for the FTC Merger.  However, the FTC Plan of Merger provides
that if the FTC Merger is not consummated as a direct or indirect consequence of
a change of control of Keystone or FTC, the party experiencing

                                      -20-
<PAGE>
 
the change of control shall reimburse the other party for all of its reasonable
out-of-pocket expenses incurred in connection with the FTC Plan of Merger.


Effective Date of the FTC Merger

     It is presently anticipated that if the FTC Plan of Merger is approved by
the shareholders of Keystone and FTC, the FTC Merger will become effective in
the second quarter of 1997.  However, as noted above, consummation of the FTC
Merger is subject to the satisfaction of a number of conditions, some of which
cannot be waived.  There can be no assurance that all conditions to the FTC
Merger will be satisfied or, if satisfied, that they will be satisfied in time
to permit the FTC Merger to become effective within the anticipated time frame.
In addition, as also noted above, Keystone and FTC retain the power to abandon
the FTC Merger or to extend the time for performance of conditions or
obligations necessary to its consummation, notwithstanding prior shareholder
approval.

                           INFORMATION CONCERNING THE
                       PRO FORMA COMBINED FINANCIAL DATA

     The FTC Merger will be accounted for by Keystone under the pooling-of-
interests method of accounting, which views the FTC Merger as a uniting of the
separate ownership interests of Keystone and FTC through an exchange of shares.
As such, the pro forma financial information which follows represents the
combined historical financial data of Keystone and FTC, subject only to certain
adjustments described in the notes to the data presented.  Certain
reclassifications have been made to conform FTC's presentation with Keystone's
presentation.  There is no impact on net income from these reclassifications.
Intercompany transactions between Keystone and FTC are immaterial and,
accordingly, have not been eliminated.

     The FFWM Merger will be accounted for by Keystone under the purchase method
of accounting.  See "FFWM Plan of Merger--Accounting Treatment."  Pro forma
financial information concerning the FFWM Merger is not included herein.  The
addition of FFWM would not have materially affected the pro forma combined
financial information as presented.

     The pro forma financial information is unaudited and is not necessarily
indicative of the financial condition or the results of operations of Keystone
as they would have been had the FTC Merger been effective during the periods
presented, or as they may be in the future.  The pro forma financial information
should be read in conjunction with the historical financial statements of
Keystone and FTC, including the notes thereto, incorporated by reference herein.
See "Information Concerning Keystone--Keystone Documents Incorporated by
Reference," and "Information Concerning FTC--FTC Documents Incorporated by

                              FFWM PLAN OF MERGER
                                        
     This section of the Joint Proxy Statement/Prospectus describes certain of
the more important aspects of the FFWM Plan of Merger.  The following
description does not purport to be complete and is qualified in its entirety by
reference to the FFWM Plan of Merger, which has been filed with the SEC as an
exhibit to the Registration Statement.  The FFWM Plan of Merger is incorporated
in this Joint Proxy Statement/Prospectus by reference to such filing and is
available upon request.  See "Available Information."


The FFWM Merger

     The FFWM Plan of Merger provides for a merger of FFWM and Keystone in which
Keystone will be the surviving corporation.  In the FFWM Merger, each of the
approximately [2,167,896] outstanding shares of FFWM Common Stock (other than
shares subject to dissenters' rights) will be converted into the right to
receive either 1.29 shares of Keystone Common Stock or an equivalent amount of
cash, as elected by the holder in the manner and subject to the limitations
described below.  See "Elections by FFWM Shareholders," "Limitations on
Effectiveness of Elections" and "Conversion of FFWM Shares."  The FFWM Merger
will not result in any change in the shares of Keystone Common Stock held by the
current Keystone shareholders.

     Keystone is a bank holding company with its principal executive offices in
Harrisburg, Pennsylvania.  Its bank subsidiaries are American Trust Bank,
Cumberland, Maryland, Frankford Bank, N.A., Horsham, Pennsylvania; Keystone
National Bank, Lancaster, Pennsylvania; Mid-State Bank and Trust Company,
Altoona, Pennsylvania; Northern Central Bank, Williamsport, Pennsylvania; and
Pennsylvania National Bank and Trust Company, Pottsville, Pennsylvania, which
operate a combined total of 140 banking offices in central and southeastern
Pennsylvania, western Maryland and northeastern West Virginia.  It also has a
number of nonbank subsidiaries and divisions which provide services to Keystone
and its customers, including brokerage, investment, mortgage banking, leasing
and insurance.  See "Summary--The Parties--Keystone" and "Keystone Documents
Incorporated by Reference."

     FFWM is a thrift holding company with its principal executive offices in
Cumberland, Maryland. Its principal subsidiary is First Federal Savings Bank of
Western Maryland ("First Federal"), which operates 10 banking offices in
Allegany, Garrett and Washington Counties in Western Maryland. See "Summary--The
Parties--FFWM" and "FFWM Documents Incorporated by Reference."

     As a result of the FFWM Merger, Keystone will acquire all of the assets and
liabilities of FFWM, and FFWM will cease to exist as a separate corporation.  It
is contemplated that contemporaneously with the FFWM Merger, FFWM's subsidiary,
First Federal, will be merged into American Trust Bank, one of Keystone's bank
subsidiaries (the "Bank Merger").


Background of the FFWM Merger

     In May 1996, FFWM received a proposal from its largest shareholder
requesting that the Board of Directors take steps to achieve a sale or merger of
FFWM. Further, this shareholder later indicated his intention to nominate an
alternative slate for election to FFWM's Board of Directors at the Annual
Meeting of Shareholders, anticipated to be held in October 1996.

     During mid-August 1996, management contacted the investment banking firm of
Alex. Brown & Sons Incorporated ("Alex. Brown") to discuss its possible
engagement to assist FFWM in evaluating alternatives to maximize shareholder
value. After discussions with management, Alex. Brown attended a meeting of
FFWM's Board of Directors on August 19, 1996 and following a presentation to the
Board, was engaged by FFWM as its financial advisor in order to assist the Board
in exploring and evaluating the various options available to FFWM to maximize
shareholder value, including the possible sale of FFWM. As disclosed in the
press release issued on the

                                      -33-
<PAGE>
 
same day, the Board determined that it was appropriate to identify potential
acquirors and to pursue discussions with interested parties, although no
assurance was given that discussions would occur or, if discussions were to
occur, that they would result in an offer being made to FFWM or that the Board
would determine that any such offer, if received, would be in the best interest
of FFWM's shareholders.

     Later in August 1996, Alex. Brown began the process of contacting 31
parties whom Alex. Brown believed might have an interest in acquiring FFWM.  Of
this number, 18 parties signed confidentiality agreements and received copies of
a confidential offering memorandum.  On September 10, 1996, Alex. Brown received
four preliminary indications of interest regarding the possible acquisition of
FFWM.  Each of these four parties proceeded to conduct an extensive due
diligence review of FFWM's business, operations and financial condition.  On
October 10, 1996 three parties submitted formal proposals regarding the possible
acquisition of FFWM.

     On August 30, 1996, the shareholder proposal relating to the sale of FFWM
was formally withdrawn.  FFWM's largest shareholder also decided not to nominate
an alternative slate in opposition to the Board's nominees for election as
directors of FFWM.  To FFWM's knowledge, each of these actions occurred without
the benefit of any knowledge, other than from publicly available information,
concerning the above-described events.

     During the remainder of October 1996, management, together with Alex. Brown
and legal counsel, evaluated the three proposals and continued to discuss with
each party the terms and conditions of their respective proposal.

     At a meeting of FFWM's Board of Directors held on November 6, 1996,
management, as well as FFWM's legal counsel and Alex. Brown, reviewed the terms
and conditions of the three proposals, two of which, including the proposal from
Keystone, were viewed as the most potentially advantageous to FFWM's
shareholders.  After a thorough review and discussion of the terms, conditions
and relative levels of risk associated with each of these proposals, the Board
determined to authorize management, with the assistance of Alex. Brown and legal
counsel, to negotiate a definitive agreement with the competing bidder and to
conduct due diligence on the competing bidder's business, operations and
financial condition.  However, the Board specifically reserved its right, in the
exercise of its fiduciary obligations, to reevaluate these competing proposals
if there should be any significant change in the terms, conditions or relative
levels of risk associated with either or both of the proposals.  Keystone was
informed by Alex. Brown of the Boards decision to proceed with the competing
bidder.

     During the course of negotiations with the competing bidder, the competing
bidder introduced several issues which FFWM believed were not customary in a
transaction of this type. While the negotiations with the competing bidder were
in process, FFWM was contacted by Keystone and informed that Keystone believed
that it had satisfactorily addressed FFWM's stated concerns with its proposal
and was prepared to improve upon its proposal. Management, together with Alex.
Brown and legal counsel, verified Keystone's representation that it had
addressed FFWM's stated concerns with Keystone's proposal. On or about November
20, 1996, Alex. Brown informed the competing bidder that Keystone had, through
its own actions, reemerged as a potential acquiror and that management, upon the
advice of Alex. Brown and legal counsel, believed that it was obligated to
present to FFWM's Board of Directors the change in circumstances relating to the
terms of both the competing bidder's proposal and Keystone's proposal.

     On November 22, 1996, FFWM's Board of Directors met and was informed by
management, together with Alex. Brown and legal counsel, of the then existing
terms, conditions and relative levels of risk associated with the proposals by
the competing bidder and Keystone.  After a lengthy discussion, and while not
terminating negotiations with the competing bidder, the Board determined to
authorize management, with the assistance of Alex. Brown and legal counsel, to
negotiate a definitive agreement with Keystone.  Management also began
conducting due diligence on Keystone's business, operations and financial
condition.

     Negotiation of a definitive agreement with Keystone was completed promptly
and at a meeting of FFWM's Board of Directors held on November 26, 1996,
management of FFWM, together with Alex. Brown and legal counsel, reviewed among
other things, the terms of the proposed FFWM Merger, the terms of the FFWM Plan
of Merger and a summary of management's due diligence findings.  Based on that
review and consideration

                                      -34-
<PAGE>
 
of the factors discussed herein, including the written fairness opinion provided
by Alex. Brown, FFWM's Board of Directors unanimously approved and authorized
the execution of the FFWM Plan of Merger.


Reasons for the FFWM Merger

     FFWM. In reaching its determination that the FFWM Merger and the FFWM Plan
of Merger are fair to, and in the best interests of, FFWM and its shareholders,
FFWM's Board of Directors consulted with its financial advisor, as well as with
FFWM's management, and considered a number of factors, including, without
limitation, the following: (i) the Board of Directors' belief that the terms of
the FFWM Plan of Merger are attractive in that the FFWM Plan of Merger allows
FFWM's shareholders, subject to specified limitations, to choose whether to
accept cash or to become shareholders of Keystone, a company that the Board of
Directors believes has positive future prospects; (ii) the written opinion of
Alex. Brown that the consideration is fair to FFWM's shareholders from a
financial point of view, (iii) pro forma financial information on the FFWM
Merger, including, among other things, earnings per share, dilution analysis and
ratio impact information; (iv) the sustainability of core earnings by Keystone
and potential for growth; (v) the tax-free nature of the transaction to FFWM and
shareholders who receive solely shares of Keystone Common Stock in connection
with the FFWM Merger; (vi) historical stock price information for both Keystone
and FFWM; (vii) the Board's review, based on a presentation by FFWM's management
regarding FFWM's due diligence and its analysis of the business, operations,
management, earnings and financial condition of Keystone on both a historical
and a prospective basis, of (A) the enhanced opportunities for operating
efficiencies, particularly in terms of integration of operations and support
functions such as product development, asset-liability management, marketing,
data processing, loan review and finance and accounting, that could result from
the FFWM Merger and (B) the enhanced opportunities for growth that the FFWM
Merger would make possible, particularly the ability to access the managerial
and other resources of Keystone in designing future products and services that
FFWM does not now offer and in responding to changing competitive, technological
and regulatory environments; (viii) the Board's belief that the combined
enterprise, having a greater size and greater resources than FFWM, could offer
FFWM's customers a broader range of products and services than FFWM presently
offers as an independent entity; (ix) the Board's review of alternatives to the
FFWM Merger (including the alternatives of remaining independent and growing
internally, remaining independent for a period of time and then selling FFWM and
remaining independent and growing through future acquisitions), including the
range of possible values to FFWM's shareholders obtainable through
implementation of such alternatives and the timing and likelihood of actually
receiving such values; (x) the Board's review of the competing proposals, as
discussed above; (xi) the Board's review of multiples of book value, earnings
per share and market price to be paid by Keystone and paid by other acquirors in
other comparable recent acquisitions of savings banks and thrifts; and (xii) the
current and prospective economic environment and competitive constraints facing
financial institutions, including FFWM and Keystone.

     Keystone.  Through the merger of FFWM's subsidiary, First Federal, with
Keystone's subsidiary, American Trust Bank, Keystone seeks to increase American
Trust Bank's market penetration in the areas currently served by both banks and
to extend American Trust Bank's market geographically.  American Trust Bank has
offices in Allegany and Garret Counties in Maryland and Mineral County, West
Virginia.  First Federal has eight offices in Allegany County, one office in
Garrett County, and one office in Washington County, Maryland.  At September 30,
1996, First Federal had total assets of $346 million and deposits of $281
million.  Of First Federal's total assets, approximately 66% consist of consumer
loans and residential mortgages.  Keystone hopes following the merger to retain
First Federal's depositors and consumer borrowers and thereby significantly
increase its retail customer base.  In turn, American Trust Bank will have the
opportunity to increase its earnings by expanding banking relationships with its
new customers by offering them products and services not presently offered by
First Federal.  Keystone believes that the merger may enable it to realize cost
efficiencies at the same time that it expands its customer base.  Finally, the
merger will enable American Trust Bank to expand its market geographically, both
in the counties in which both banks have offices and into the city of
Hagerstown, in Washington County, Maryland, where First Federal currently has an
office, but American Trust Bank does not.

Required Vote; Management Recommendation

     Approval of the FFWM Plan of Merger requires the affirmative vote of the
holders of a majority of the outstanding shares of FFWM Common Stock.  Because
approval requires the affirmative vote of a majority of all outstanding FFWM
shares, an abstention or a broker non-vote will have the same legal effect as a
vote against approval of the FFWM Plan of Merger.  THE BOARD OF DIRECTORS OF
FFWM UNANIMOUSLY RECOMMENDS THAT FFWM SHAREHOLDERS VOTE "FOR" APPROVAL OF THE
PLAN OF MERGER.

     The Board of Directors of Keystone has approved the FFWM Plan of Merger,
and under the Pennsylvania Business Corporation Law no approval of the FFWM Plan
of Merger by the shareholders of Keystone is required.


Voting Agreements

     In connection with the FFWM Plan of Merger, the directors of FFWM have
entered into agreements to vote certain shares of FFWM Common Stock beneficially
owned by them in favor of the FFWM Merger.  The directors of FFWM have agreed
with Keystone that they will vote in favor of the FFWM Merger all shares of FFWM
Common Stock owned by them as individuals or (to the extent of their
proportionate interest) jointly with other persons, and that they will use their
best efforts to cause any other shares of FFWM Common Stock over which they have
or share voting power to be voted in favor of the FFWM Merger.  In the
aggregate, these agreements commit 141,134 shares of FFWM Common Stock (6.5% of
the outstanding shares) to be voted in favor of the FFWM Merger.

     The agreements further provide that with respect to shares of FFWM Common
Stock owned by the directors as individuals or (to the extent of the director's
proportionate interest) jointly with other persons (collectively, "Shares"), the
directors will not until the FFWM Merger has been consummated or the FFWM Plan
of Merger has been terminated:  (1) vote Shares in favor of any other merger or
transaction which would have the effect of a person other than Keystone
acquiring control of FFWM or First Federal or (2) sell or otherwise transfer
Shares (i) pursuant to any tender offer or similar proposal made by a person
other than Keystone or an affiliate, (ii) to any person other than Keystone or
an affiliate seeking to obtain control of FFWM or First Federal or (iii) for the
principal purpose of avoiding the director's obligations under the agreement.
The agreements define "control" as the ability to direct (1) the voting of 10%
or more of the shares eligible to vote in an election of directors or (2)  the
management and policies of FFWM or First Federal.

     The agreements are applicable to the directors only in their capacities as
shareholders and do not affect the exercise of their responsibilities as
directors or officers.  The agreements also do not apply to any shares of FFWM
Common Stock held by a director as a trustee or other fiduciary.  No monetary or
other compensation was paid to any FFWM director for entering into these
agreements.

     The foregoing is a summary of the material terms of the voting agreements.
The form of these agreements has been filed with the SEC as an exhibit to the
Registration Statement.  Such form is incorporated herein by reference, and the
foregoing summary of the agreements is qualified in its entirety by reference to
such filing.


Opinion of FFWM Financial Advisor

     FFWM retained Alex. Brown to act as FFWM's financial advisor in connection
with the FFWM Merger and related matters. Alex. Brown was selected to act as
FFWM's financial advisor based upon its qualifications, expertise and
reputation, as well as Alex. Brown's prior investment banking relationship and
familiarity with FFWM. Alex. Brown regularly publishes research reports
regarding the financial services industry and the businesses and securities of
publicly owned companies in that industry.

                                      -36-
<PAGE>
 
     On November 26, 1996, at the meeting at which the FFWM Board approved and
adopted the FFWM Plan of Merger, Alex. Brown delivered a written opinion to the
FFWM Board of Directors that, as of such date, the Total Consideration (defined
below) to be received by the shareholders of FFWM, was fair to the shareholders
of FFWM from a financial point of view (the "Opinion").  Pursuant to the
Agreement, each share of FFWM common stock issued and outstanding immediately
prior to the effective time of the merger with Keystone will be converted into
the right to receive, at the election of the holder thereof, either (i) 1.29
shares (the "Exchange Ratio") of common stock of Keystone or (ii) an amount in
cash equal to the Exchange Ratio multiplied by Keystone's average closing bid
price for the 20 consecutive trading days preceding the sixth trading day prior
to the closing date.  The total consideration ("Total Consideration") shall mean
the sum of the stock election described under (i), which will equal
approximately 60% of the Total Consideration, and the cash election described
under (ii), which will equal approximately 40% of the Total Consideration.  No
limitations were imposed by the FFWM Board of Directors upon Alex. Brown with
respect to the investigations made or procedures followed by it in rendering the
Opinion.

     The full text of the Opinion, which sets forth assumptions made, matters
considered and limits on the review undertaken, is attached hereto as Annex III
and is incorporated herein by reference.  FFWM shareholders are urged to read
the Opinion in its entirety.  The following summary of the Opinion is qualified
in its entirety by reference to the full text of the Opinion.

     In rendering the Opinion, Alex. Brown (i) reviewed the FFWM Plan of Merger,
certain publicly available business and financial information concerning FFWM
and Keystone, and certain internal financial analyses and forecasts for FFWM and
Keystone prepared by their respective managements; (ii) held discussions with
members of senior management of FFWM and Keystone regarding the past and current
business operations, financial condition, and future prospects of their
organizations; (iii) reviewed the reported price and trading activity for FFWM
Common Stock and Keystone Common Stock and compared certain financial and stock
market information for each of FFWM and Keystone with similar information for
certain other financial institutions, the securities of which are publicly
traded; (iv) reviewed the financial terms of certain recent business
combinations in the financial institutions industry which Alex. Brown deemed
comparable in whole or in part; and (v) performed such other studies and
analyses as Alex. Brown considered appropriate.

     Alex. Brown relied without independent verification upon the accuracy and
completeness of all of the financial and other information reviewed by and
discussed with it for purposes of its Opinion.  With respect to the financial
forecasts reviewed by Alex. Brown in rendering its Opinion, Alex. Brown assumed
that such financial forecasts were reasonably prepared on bases reflecting the
best currently available estimates and judgments of the respective managements
of each of FFWM and Keystone as to the future financial performance of FFWM and
Keystone.  Alex. Brown did not make an independent evaluation or appraisal of
the assets or liabilities of FFWM or Keystone, nor was it furnished with any
such appraisal.

     The summary set forth below does not purport to be a complete description
of the analyses performed by Alex. Brown in this regard.  The preparation of a
fairness opinion involves various determinations as to the most appropriate and
relevant methods of financial analysis and the application of these methods to
the particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description.  Accordingly, notwithstanding the separate
factors discussed below, Alex. Brown believes that its analyses must be
considered as a whole and that selecting portions of its analyses and of the
factors considered by it, without considering all analyses and factors, could
create an incomplete view of the evaluation process underlying its opinion.  No
one of the analyses performed by Alex. Brown was assigned a greater significance
than any other.  In performing its analyses, Alex. Brown made numerous
assumptions with respect to industry performance, business and economic
conditions and other matters, many of which are beyond FFWM's or Keystone's
control.  The analyses performed by Alex. Brown are not necessarily indicative
of actual values or future results, which may be significantly more or less
favorable than suggested by such analyses.  Additionally, analyses relating to
the values of businesses do not purport to be appraisals or to reflect the
prices at which businesses actually may be sold.

     Analysis of Selected Publicly Traded Companies.  In preparing the Opinion,
Alex. Brown, using publicly available information, compared selected financial
information, including book value, tangible book value, latest

                                      -37-
<PAGE>
 
twelve months ("LTM") earnings, 1996 estimated earnings, 1997 estimated
earnings, asset quality ratios and loan loss reserve levels, for FFWM and its
peer group of savings bank organizations.

     The peer group was comprised of savings banks located in Maryland, Virginia
and West Virginia that possessed asset bases between $100 million and $500
million ("Peer Group"). The Peer Group included American National Bancorp
(ANBK), Bedford Bancshares, Inc. (BFSB), Community Financial Corp. (CFFC),
Equitable Federal Savings Bank (EQSB), Essex Bancorp, Inc. (ESX), Fed One
Bancorp (FOBC), Guaranty Financial Corp. (GSLC), Harbor Federal Bancorp, Inc.
(HRBF), and Washington Savings Bank, FSB (WSB). As of November 25, 1996, the
relative multiples implied by the market price of FFWM's Common Stock and the
mean market price of the common stock of the Peer Group to such selected
financial data were: to LTM earnings 15.2x for FFWM and 11.2x for the Peer
Group; to 1996 I/B/E/S (Institutional Brokerage Estimation Service) estimated
earnings per share, 14.2x for FFWM and 11.8x for the Peer Group; to 1997 I/B/E/S
estimated earnings per share, 13.7x for FFWM and 11.5x for the Peer Group; to
stated book value, 146% for FFWM and 104% for the Peer Group; to tangible book
value, 146% for FFWM and 104% for the Peer Group; and to total assets, 17.1% for
FFWM and 9.8% for the Peer Group.

     Analysis of Selected Acquisition Transactions.  In preparing the Opinion,
Alex. Brown analyzed certain selected merger and acquisition transactions for
savings banks based upon the acquisition price relative to stated book value,
normalized book value (which assumes normalized book multiple is paid for all
equity up to 8.0% of assets and then dollar-for-dollar for all additional
equity), tangible book value, LTM earnings, total assets and the premiums to
core deposits and market price.  The market price premium is measured against
the market price of the common stock one month prior to the acquisition
announcement.  The analysis included a review and comparison of the mean
multiples represented by a sample of recently effected or pending savings bank
acquisitions nationwide having a transaction value greater than $20 million and
less than $100 million which were announced since January 1, 1995 (a total of 59
transactions) ("National Transactions"), as segmented into:  (i) transactions in
which the selling savings bank was headquartered in the Mid-Atlantic Region (15)
("Regional Transactions"); (ii) transactions in which the selling savings bank
achieved a return on average assets ("ROAA") between 0.80% and 1.20% in the year
of its announced acquisition (26) ("Profitability-Segmented Transactions"); and
(iii) transactions in which the selling savings bank had a tangible equity to
assets ratio greater than 10.0% (27) ("Capital-Segmented Transactions").

     The relative multiples implied by the Total Consideration ($34.19 implied
per share value to FFWM shareholders as of November 25, 1996) and each of the
selected acquisition transaction segmentations, respectively, are provided in
the following table:

     Contribution Analysis.  Alex. Brown also determined the contribution by
FFWM of key historical balance sheet items (including assets, loans and
deposits) and selected historical income statement items (including latest
twelve months net interest income and net income) to the resulting pro forma
entity, as compared to the implied value contributed by Keystone in stock and
cash that was received by current FFWM shareholders in aggregate as a result of
the acquisition (as of the exchange ratio on November 26, 1996).

     The relative levels of contribution by FFWM in these selected areas and the
implied value contributed by Keystone in stock and cash received by current FFWM
shareholders, in aggregate, are presented in the following table:

     Impact on FFWM Shareholders.  Based on the fixed exchange ratio that FFWM
shareholders could receive as part of the FFWM Plan of Merger, Alex. Brown was
able to determine the expected effect of the transaction to the current
shareholders of FFWM Common Stock.  The pro forma values listed in the table
below and their resulting implications to current FFWM shareholders are based on
historical and projected Keystone and FFWM financials; the 1997 estimated
earnings per share figures also assume Keystone can recognize 40% pre-tax
expense savings relating to the FFWM Merger.  As such the values listed in the
table below are not necessarily indicative of actual values, which may be
significantly more or less than such estimates.

     Discounted Dividend Analysis. Using discounted cash flow analysis, Alex.
Brown estimated the present value of the future dividend streams that FFWM could
produce over a five-year period, under different assumptions as if FFWM
performed in accordance with management's forecasts and certain variants
thereof. Alex. Brown also estimated the terminal value for FFWM's common equity
after the five-year period by applying earnings acquisition multiples (14.0 -
18.0 times) currently being received by savings bank institutions with similar
profitability ratios as FFWM is projected to have during its calendar year
ending December 31, 2001. The range of multiples used reflected a variety of
scenarios regarding the growth and profitability prospects of FFWM. The dividend
streams and terminal values were then discounted to present values using
discount rates ranging from 11.0% to 15.0%, which reflect different assumptions
regarding the required rates of return of holders or prospective buyers of
FFWM's common equity.

     Reference Range.  Based in part on the several analyses discussed above,
Alex. Brown developed, for purposes of its Opinion, a reference range for the
value of FFWM common equity of $26.50 to $34.50 per share of

                                      -39-
<PAGE>
 
FFWM Common Stock. The values reflected in the foregoing reference range were
considered along with the other analyses performed by Alex. Brown and were not
intended to represent the price at which 100% of FFWM Common Stock could
actually be sold. The foregoing reference ranges were based in part on the
application of economic and financial models and are not necessarily indicative
of actual values; which may be significantly more or less than such estimates.
The reference ranges do not purport to be appraisals.

     Compensation of Financial Advisor.  Pursuant to the terms of an engagement
letter dated August 19, 1996, FFWM has agreed to pay Alex. Brown a fee of 1.0%
of the aggregate consideration received by FFWM shareholders in the FFWM Merger.
This fee is payable to Alex. Brown upon consummation of the FFWM Merger, and is
estimated to be approximately $750,000, assuming that the per share
consideration paid to FFWM shareholders is $34.19 at the consummation of the
FFWM Merger.  Whether or not the FFWM Merger is consummated, FFWM also has
agreed to pay all of Alex. Brown's out-of-pocket expenses, including fees and
disbursements of counsel, incurred by Alex. Brown in carrying out its duties
under its engagement, and to indemnify Alex. Brown and certain related persons
against certain liabilities relating to or arising out of its engagement.


Elections by FFWM Shareholders

     Pursuant to the FFWM Plan of Merger, each holder of record of FFWM Common
Stock may elect to receive, in exchange for each share of FFWM Common Stock held
of record by such holder, either solely (1) 1.29 shares of Keystone Common Stock
(the "Stock Election") or (2) an amount in cash equal to 1.29 times the average
of the closing bid prices for the Keystone Common Stock on the NASDAQ National
Market System for the 20 trading days ending with the sixth trading day
immediately preceding the closing date for the FFWM Merger (the "Cash
Election").

     No Partial Elections.  Except as discussed below with respect to nominee
holders, each FFWM shareholder will be required to make the same Election
(either solely the Stock Election or solely the Cash Election) for all shares of
FFWM Common Stock held of record by such holder, whether such shares are held in
a single or in multiple shareholder accounts.  For purposes of the FFWM Plan of
Merger, a person holding shares of record individually will be treated as a
separate holder from the same person holding shares of record jointly with
another person or in a fiduciary capacity.

     Manner of Election.  The proxy card accompanying this Joint Proxy
Statement/Prospectus as sent to each FFWM shareholder of record on the record
date for the FFWM Special Meeting contains a Form of Election on which such
shareholders may designate either the Stock Election or the Cash Election.
Persons who become FFWM shareholders of record after the record date for the
FFWM Special Meeting may obtain a Form of Election by writing to First Financial
Corporation of Western Maryland, 118 Baltimore Street, Cumberland, Maryland
21502, Attention:  William C. Marsh, Executive Vice President and Chief
Financial Officer.

     To be effective, a Form of Election (or a facsimile thereof), properly
completed and signed, must be received by FFWM at the above address not later
than 10:00 a.m., local time, on March 17, 1997 (the "Election Deadline").  Any
FFWM shareholder whose Form of Election is not received prior to the Election
Deadline will be deemed to have made either the Stock Election or the Cash
Election, as determined by Keystone in order to satisfy the Minimum Stock and
Maximum Stock Limitations described below.  See "Limitations on Effectiveness of
Elections."

     Revocability of Elections.  Any FFWM shareholder who has submitted a Form
of Election may change it by submitting a revised Form of Election (or a
facsimile thereof) which is received by FFWM prior to the Election Deadline.  In
the event multiple Forms of Election are submitted by the same shareholder, the
latest dated Form of Election will control.

     Upon the Election Deadline, Elections will become irrevocable except to the
extent that changes are permitted, in the discretion of Keystone, to satisfy the
Minimum Stock and Maximum Stock Limitations described

                                      -40-
<PAGE>
 
below. See "Limitations on Effectiveness of Elections." In the event any shares
of FFWM Common Stock are transferred after an Election has been made (or is
deemed to have been made), the transferee of such shares will be bound by such
Election unless a revised Form of Election (or a facsimile thereof) is received
by FFWM prior to the Election Deadline.

     Nominee Holders.  A holder of record of FFWM Common Stock who is a nominee
only may submit one or more Forms of Election designating a combination of
Elections, provided that such holder certifies to the satisfaction of Keystone
that such shares are held as a nominee for more than one beneficial owner and
that either solely the Stock Election or solely the Cash Election has been made
with respect to all shares held as nominee for any one beneficial owner.  Each
beneficial owner for which such a Form of Election is submitted will be treated
as a separate holder of FFWM Common Stock for the purpose of the Minimum Stock
and Maximum Stock Limitations described below.


Limitations on Effectiveness of Elections

     The effectiveness of any Election made by an FFWM shareholder as described
above is subject to the following limitations:

          (1)  Minimum Stock Limitation.  The aggregate market value on the day
     prior to the FFWM Merger of all whole shares of Keystone Common Stock to be
     issued pursuant to the Stock Election (the "Stock Value") must be at least
     equal to 55% of the Total Consideration (defined below) payable to FFWM
     shareholders in connection with the FFWM Merger; and

          (2)  Maximum Stock Limitation.  The Stock Value may not exceed 60% (or
     such greater percentage as Keystone in its sole discretion may determine to
     permit) of the Total Consideration except as necessary to assure that
     either solely the Stock Election or solely the Cash Election shall be in
     effect for each holder of FFWM Common Stock.

     For purposes of these limitations, the "Total Consideration" payable to
FFWM Shareholders in connection with the FFWM Merger is defined as the sum of
(1) the Stock Value plus (2) the aggregate amount of cash which may be payable
by Keystone (i)  to FFWM shareholders making the Cash Election, (ii) in lieu of
fractional shares of Keystone Common Stock to FFWM shareholders making the Stock
Election (see "Conversion of FFWM Shares" below) and (iii) to FFWM shareholders
who may perfect their rights as dissenting shareholders, as determined by
Keystone as of the effective date of the FFWM Merger (see "Dissenters' Rights of
FFWM Shareholders" below).

     In applying these limitations, Keystone will first treat any holders of
FFWM Common Stock who have not submitted a timely Form of Election ("non-
electing holders") as having made either the Stock Election as necessary to
satisfy the Minimum Stock Limitation or the Cash Election as necessary to
satisfy the Maximum Stock Limitation.

     If after allocating all non-electing holders to the Stock Election,
Keystone determines that giving effect to all Cash Elections made by FFWM
shareholders would result in the Minimum Stock Limitation not being met, the
Cash Elections made by the FFWM shareholders holding the smallest numbers of
shares of FFWM Common Stock will automatically be converted to the Stock
Election in the order of their holdings of FFWM Common Stock, so that the holder
of the smallest number of shares will be converted first, the holder of the
second smallest number of shares will be converted second, and so on, until the
Minimum Stock Limitation is satisfied.

     If after allocating all non-electing holders to the Cash Election, Keystone
determines that giving effect to all Stock Elections made by FFWM shareholders
would result in the Maximum Stock Limitation being exceeded, the Stock Elections
made by the FFWM shareholders holding the smallest numbers of shares of FFWM
Common Stock will automatically be converted to the Cash Election in the order
of their holdings of FFWM Common Stock, in the same manner as described in the
immediately preceding paragraph, until the Maximum Stock Limitation is
satisfied.

                                      -41-

Additional Procedures and Determinations

     Keystone has the right to establish additional procedures and to make
reasonable determinations not inconsistent with the FFWM Plan of Merger
governing any matters in connection therewith, including procedures and
determinations as to the manner, form and validity of Elections, the necessity
for, manner and extent of conversions of Elections resulting from the Minimum
Stock and Maximum Stock Limitations and the ranking of holders of FFWM Common
Stock for purposes of such conversions.


Conversion of FFWM Shares

     On the effective date of the FFWM Merger, (1) each share of FFWM Common
Stock held by an FFWM shareholder who has made or is deemed to have made the
Stock Election will be converted into the right to receive 1.29 shares of
Keystone Common Stock, and (2) each share of FFWM Common Stock held by an FFWM
shareholder who has made or is deemed to have made the Cash Election will be
converted into the right to receive an amount in cash equal to 1.29 times the
average of the closing bid prices for the Keystone Common Stock on the NASDAQ
National Market System for the 20 trading days ending with the sixth trading day
immediately preceding the closing date for the FFWM Merger (the "Average
Keystone Price").  On February ___, 1997, the closing bid price for Keystone
Common Stock reported on the NASDAQ National Market System was $_____.

     Surrender of Certificates.  As promptly as practicable after the effective
date of the FFWM Merger, Keystone will send to each shareholder of record of
FFWM immediately prior to the FFWM Merger a letter of transmittal containing
instructions on how to effect the exchange of FFWM Common Stock certificates for
certificates representing the shares of Keystone Common Stock or for the cash
into which their FFWM shares have been converted.  FFWM shareholders should not
send in their certificates until they receive such written instructions.
However, certificates should be surrendered promptly after instructions to do so
are received.

     No interest will accrue or be payable in respect of any cash payable on
surrender for exchange of FFWM Common Stock certificates, and no such cash will
be paid or Keystone Common Stock certificates issued to any former FFWM
shareholder until such shareholder's FFWM Common Stock certificates are
surrendered for exchange as provided in the letter of transmittal.

     Any dividends declared on Keystone Common Stock after the effective date of
the FFWM Merger will apply to all whole shares of Keystone Common Stock into
which shares of FFWM Common Stock have been converted in the FFWM Merger under
the Stock Election.  However, no former FFWM shareholder will be entitled to
receive any such dividend until such shareholder's FFWM Common Stock
certificates have been surrendered for exchange as provided in the letter of
transmittal.  Upon such surrender the former FFWM shareholder will be entitled
to receive all such dividends payable on the whole shares of Keystone Common
Stock represented by the surrendered certificate or certificates (without
interest thereon and less the amount of taxes, if any, which may have been
imposed or paid thereon).

     Payment for Fractional Shares.  No fractional shares of Keystone Common
Stock will be issued in connection with the FFWM Merger.  Instead, each FFWM
shareholder who surrenders for exchange FFWM Common Stock certificates
representing a fraction of a share of Keystone Common Stock will be entitled to
receive, in addition to a certificate for the whole shares of Keystone Common
Stock represented by the surrendered certificates, cash in amount equal to such
fractional part of a share multiplied by the value of $26.50 for one whole share
of Keystone Common Stock.

     Unexchanged Certificates.  On the effective date of the FFWM Merger, the
stock transfer books for FFWM Common Stock will be closed, and no further
transfers of FFWM Common Stock will be made or recognized.  Certificates for
FFWM Common Stock not surrendered for exchange will entitle the holder only to

                                      -42-
<PAGE>
 
receive, upon surrender as provided in the letter of transmittal, either (1) a
certificate for the whole shares of Keystone Common Stock into which the shares
represented thereby have been converted under the Stock Election, plus payment
of any amount for a fractional share or dividends to which such holder is
entitled as outlined above, or (2) the cash into which the shares represented
thereby have been converted under the Cash Election.

     If the FFWM Merger becomes effective and any former FFWM shareholder who
makes or is deemed to have made the Stock Election does not surrender his or her
FFWM Common Stock certificates for exchange on or before the second anniversary
of the effective date, Keystone, at its option,  may at any time thereafter sell
such shareholder's Keystone Common Stock without notice to the shareholder.
After any such sale, the sole right of such shareholder shall be to receive,
upon surrender of the shareholder's FFWM Common Stock certificates, the net
proceeds of the sale (without interest and less the amount of any taxes which
may have been imposed or paid thereon).

     Keystone Shareholder Rights Plan.  If no Distribution Date under Keystone's
shareholder rights plan (see "Comparison of Keystone Common Stock and FFWM
Common Stock--Keystone Shareholder Rights Plan") shall have occurred prior to
the effective date of the FFWM Merger, then each share of Keystone Common Stock
issued in the FFWM Merger shall also evidence one Right under Keystone's
shareholder rights plan.  If the Distribution Date shall have occurred, then it
is a condition to the FFWM Merger that Keystone take one of the actions set
forth under "Conditions to the FFWM Merger" below.

     Adjustment of Exchange Ratio. The FFWM Plan of Merger contains provisions
for the proportionate adjustment of the exchange ratio to be used for converting
FFWM Common Stock into Keystone Common Stock or cash in the FFWM Merger if a
stock dividend, stock split, reclassification or similar event involving the
Keystone Common Stock or the FFWM Common Stock occurs prior to the FFWM Merger.
The exchange ratio of 1.29 shares of Keystone Common Stock for each share of
FFWM Common Stock, as the same may be adjusted pursuant to such provisions, is
sometimes referred to below as the "Exchange Ratio." See also "Amendment, Waiver
and Termination" below for a discussion of Keystone's right to terminate the
FFWM Plan of Merger in the event the average closing bid price for Keystone
Common Stock for a prescribed 20-trading-day period exceeds $31.80, and FFWM's
right to prevent such termination by electing to proportionately reduce the
Exchange Ratio.


Tax Consequences to FFWM Shareholders

     Federal Tax Opinion.  The FFWM Plan of Merger requires as a condition to
the FFWM Merger that an opinion of counsel or of independent public accountants
be received by Keystone and FFWM to the effect that for purposes of federal
income tax:

          (1)  The FFWM Merger will constitute a reorganization within the
     meaning of Section 368 of the Internal Revenue Code of 1986, as amended
     (the "Code");

          (2)  Except for cash received in lieu of fractional shares, no income,
     gain or loss will be recognized by the shareholders of FFWM who receive
     solely Keystone Common Stock on the exchange of their shares of FFWM Common
     Stock;

          (3)  The basis of shares of Keystone Common Stock to be received by
     shareholders of FFWM will be the same as the basis of the shares of FFWM
     Common Stock exchanged therefor; and

          (4)  The holding period of the shares of Keystone Common Stock
     received by shareholders of FFWM will include the period during which the
     FFWM Common Stock exchanged therefor was held by the FFWM shareholder,
     provided that the FFWM Common Stock was held as a capital asset at the
     effective time of the FFWM Merger.

     Stock Election.  An FFWM shareholder who makes or is deemed to have made
the Stock Election will not recognize gain or loss for federal income tax
purposes on the exchange of his FFWM shares for full shares of

                                      -43-
<PAGE>
 
Keystone Common Stock. However, gain or loss will be recognized upon the receipt
of cash in lieu of a fractional share interest. To compute the amount, if any,
of such gain or loss, the cost or other basis of the FFWM Common Stock exchanged
must be allocated proportionately to the total number of shares of Keystone
Common Stock received, including any fractional share interest. Gain or loss
will be recognized measured by the difference between the cash received and the
basis of the fractional share interest as so allocated. Under Section 302(a) of
the Code, any such gain or loss will generally be entitled to capital gain or
loss treatment if the FFWM Common Stock was a capital asset in the hands of the
shareholder and the cash received was not essentially equivalent to a dividend.

     If any shares of Keystone Common Stock received in the FFWM Merger are
subsequently sold, gain or loss on the sale should be computed by allocating the
cost or other basis of the FFWM Common Stock exchanged in the FFWM Merger to the
shares sold in the manner described in the preceding paragraph.  The holding
period for the shares of Keystone Common Stock received in the FFWM Merger will
include the holding period for the shares of FFWM Common Stock exchanged in
determining, for example, whether any such gain or loss is a long-term or short-
term capital gain or loss.

     Cash Election.  Where an FFWM shareholder makes or is deemed to have made
the Cash Election and receives cash in exchange for FFWM Common Stock, the cash
will be treated as received by the shareholder as a distribution in redemption
of Keystone Common Stock that the shareholder would have received if the
shareholder had made the Stock Election, subject to the provisions and
limitations of Section 302 of the Code.  Pursuant to Section 302, and assuming
that the FFWM Common Stock of such shareholder is a capital asset in the hands
of the shareholder, an FFWM shareholder who makes or is deemed to have made the
Cash Election will realize capital gain or loss on the exchange if (i) such
shareholder has no stock interest in Keystone following the FFWM Merger, (ii)
the exchange is substantially disproportionate with respect to such shareholder
or (iii) the exchange is not essentially equivalent to a dividend.  For these
purposes, an FFWM shareholder will be considered to own stock of Keystone owned
after the FFWM Merger by certain related individuals or entities under the
attribution of ownership rules set forth in Section 318 of the Code as made
applicable to Section 302 of the Code.  If none of (i), (ii) or (iii) above
applies, an FFWM shareholder who makes or is deemed to have made the Cash
Election will be treated as though the shareholder had received a dividend equal
to the cash received, taxable as ordinary income in the year in which the FFWM
Merger occurs.

     As indicated under the caption "Elections by FFWM Shareholders," each FFWM
shareholder must make the same Election for all shares of FFWM Common Stock held
in a particular capacity.  If an FFWM shareholder holds FFWM Common Stock in
more than one capacity--for example, a husband holds 100 shares individually and
he and his wife hold 100 shares as tenants by the entireties--the same Election
should be made for all such holdings.  If the same Election is not made, FFWM
shareholder may be subject to Section 356 of the Code.  Pursuant to Section 356,
the cash received may under certain circumstances be treated as a dividend,
taxable as ordinary income in the year in which the FFWM Merger occurs.

     Dissenting Shareholders.  Where an FFWM shareholder exercises dissenters'
rights and receives cash in exchange for FFWM Common Stock, the cash will be
treated as received by the shareholder as a distribution in redemption of the
FFWM Common Stock subject to the provisions and limitations of Section 302 of
the Code.  The cash received by a dissenting FFWM shareholder will be treated as
if the shares had been sold to FFWM for the cash received, and will generally be
entitled to capital gain or loss treatment under Section 302 of the Code,
provided the shares are a capital asset in the hands of the shareholder.
However, because the ownership of shares by certain individuals related to the
shareholder and by certain partnerships, estates, trusts and corporations in
which the shareholder has an interest may have an adverse impact on the tax
treatment of the cash received by the shareholder and result in it being taxed
as a dividend, an FFWM shareholder should consult with his own personal tax
advisor as to the federal, state and local tax consequences of exercising
dissenters' rights.

     Maryland Personal Income Tax.  For FFWM shareholders who are subject to the
Maryland personal income tax, the Maryland state income tax consequences of
receiving Keystone Common Stock and cash in lieu of fractional shares pursuant
to the Stock Election, cash pursuant to the Cash Election, or cash as a
dissenting shareholder are the same as they are under the Code for federal
income tax purposes, as described above.

                                      -44-
<PAGE>
 
     The foregoing is intended only as a summary of certain federal income tax
and Maryland personal income tax consequences of the FFWM Merger under existing
law and regulations, as presently interpreted by judicial decisions and
administrative rulings, all of which are subject to change without notice, and
any such change might be retroactively applied to the FFWM Merger.  Among other
things, the summary does not address state income tax consequences in states
other than Maryland, local taxes, or the federal or state income tax
considerations that may affect the treatment of a shareholder who acquired FFWM
Common Stock pursuant to an employee stock option.  Accordingly, it is
recommended that FFWM shareholders consult their own tax advisors with specific
reference to their own tax situations and potential changes in the applicable
law as to all federal, state and local tax matters in connection with the FFWM
Merger.


Boards of Directors Following the FFWM Merger

     The FFWM Merger will not result in any changes in the membership of the
Board of Directors of Keystone.  However, at the time the FFWM Merger becomes
effective, three directors of FFWM selected by Keystone will be added to the
Board of Directors of American Trust Bank, which presently consists of 12
directors.


Interests of Certain Persons in the Transaction

     Advisory Fees for FFWM Directors.  Keystone has agreed in the FFWM Plan of
Merger that, in consideration of their being available for reasonable advisory
services during the one-year period following consummation of the FFWM Merger,
Keystone will pay to each current director of FFWM who remains a director until
immediately prior to the FFWM Merger an amount equal to the fees that such
director received from FFWM during the one-year period preceding the FFWM
Merger, including retainer fees and fees for attendance at Board of Directors
and Board committee meetings.  The amount paid to any FFWM director who becomes
a member of the Board of Directors of American Trust Bank will be reduced by the
amount of fees paid to the director for service in that capacity.

     Each director of FFWM receives a retainer of $200 each month so long as the
director's rate of attendance at meetings of the Board of Directors exceeds 75%
during the immediately preceding twelve-month period.  Directors receive fees of
$500 and $100 for each meeting of the Board of Directors of First Federal and
subsidiaries thereof, respectively, attended and $50 for each committee meeting
of First Federal's Board attended.  In the fiscal year ended June 30, 1996 fees
paid to FFWM directors ranged between $12,200 and $13,400 per director.

     FFWM Executive Officer Severance Arrangements.  FFWM and First Federal (the
"Employers") are parties to an Employment Agreement with Patrick J. Coyne,
Chairman, President and Chief Executive Officer of the Employers.  The Employers
have also entered into Severance Agreements with the following Executive Vice
Presidents, Kenneth W. Andres, William C. Marsh and R. Craig Pugh.  Each of
these agreements provide that in the event of a change of control, as defined in
the agreements, the respective executive officer shall be entitled to receive a
lump sum severance payment equal to three times (Mr. Coyne) or 2.99 times
(Messrs. Andres, Marsh and Pugh) his average annual compensation for the
preceding five years or, if employed for less than five years, such shorter
period of time.  Consummation of the FFWM Plan of Merger will constitute a
change of control under the terms of each of the agreements.  Further, the
employment of each of Messrs. Coyne, Andres, Marsh and Pugh will terminate
effective on the effective date of the FFWM Merger and none of these officers
will have any continuing employment with Keystone or American Trust Bank
following the effective date.  Upon consummation of the FFWM Plan of Merger and
in satisfaction of the Employers' obligations under the terms of existing
employment, severance, stock option and incentive plan agreements, Messrs.
Coyne, Andres, Marsh and Pugh will receive pre-tax severance payments in the
amounts of [$1,334,348, $421,827, $344,152 and $445,594], respectively. These
amounts are subject to reduction to the extent, if any, that the payments would
constitute "excess parachute payments" under Section 280G of the Internal
Revenue Code.

     FFWM Directors' and Officers' Indemnification, Limitation of Liability and
Insurance.  Keystone has agreed in the FFWM Plan of Merger that following the
FFWM Merger it will provide indemnification to any present or former director,
officer or employee of FFWM and its subsidiaries with respect to any proceeding
arising out of matters existing or occurring at or prior to the effective time
of the FFWM Merger to the fullest extent, if any, that such person would have
been entitled to indemnification by FFWM under FFWM's certificate of
incorporation and bylaws.  The certificate of incorporation and bylaws of FFWM
generally require FFWM to indemnify its directors and officers, and any person
who was serving at the request of FFWM as a director, officer, employee or agent
of another corporation or enterprise, against expenses, including attorneys'
fees, liabilities, losses, judgments, fines and amounts paid in settlement
reasonably incurred in connection with any civil, criminal, administrative or
investigative proceeding in which such person is or is threatened to be made a
party is otherwise involved by reason of having served in such capacity, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of FFWM, and, with respect to any criminal
proceeding, had no reasonable cause to believe his conduct was unlawful.

     Keystone has also agreed that the provision of FFWM's certificate of
incorporation which limits the liability of its directors shall survive the FFWM
Merger and continue in full force and effect with respect to liabilities arising
out of matters existing or occurring at or prior to the effective time of the
FFWM Merger.  This provision provides that directors of FFWM shall not be liable
to the corporation or its shareholders for monetary damage for breach of
fiduciary duty as a director except for (i) a breach of the directors duty of
loyalty to the corporation or its shareholders, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) the willful or negligent payment or making by the corporation of an
unlawful dividend, stock purchase or redemption or (iv) any transaction from
which the director derived an improper personal benefit.

     Finally, Keystone has agreed to maintain for three years following the FFWM
Merger FFWM's current directors' and officers' liability insurance policy or a
substantially equivalent policy covering FFWM's directors and officers for acts
or omissions occurring prior to the FFWM Merger, provided that if the annual
cost of such policy would exceed $20,590, then Keystone would only be required
to use its reasonable efforts to obtain as much comparable insurance as is
available for that amount.

     Cashout of FFWM Director and Officer Stock Options.  Stock options for
[14,173] shares of FFWM Common Stock are presently outstanding under FFWM's
Stock Option Incentive Plan at option prices equal to the fair market value of
such shares on the dates the options were granted.  The FFWM Plan of Merger
provides that each of these options which remains outstanding and unexercised at
the time the FFWM Merger becomes effective will be converted into the right to
receive, for each share of FFWM Common Stock subject to the option, an amount in
cash equal to the excess of (1) the product of (a) the Exchange Ratio,
multiplied by (b) the Average Keystone Price, over (2) the exercise price of the
option.

     Benefit Plans and Severance Arrangements for FFWM Employees. Keystone has
agreed that as soon as administratively practicable after the FFWM Merger, it
will take appropriate action so that employees of FFWM and its subsidiaries will
be entitled to participate in Keystone employee benefit plans of general
applicability and that until such action is taken FFWM's plans shall remain in
effect. No employee of FFWM or a subsidiary who becomes an employee of Keystone
or a subsidiary shall be excluded from coverage under Keystone's medical
insurance plans on the basis of a preexisting condition that was not also
excluded under FFWM's medical insurance plans, except to the extent that such
preexisting condition was excluded from coverage under FFWM's plans. For
purposes of determining eligibility to participate in and the vesting of
benefits under Keystone's employee benefit plans, but not for purposes of
benefit accrual, Keystone will recognize years of service with FFWM or a
subsidiary prior to the FFWM Merger.

     The FFWM Plan of Merger provides that employees of FFWM and its
subsidiaries with at least one year of service prior to the FFWM Merger, other
than employees who are parties to an employment or severance agreement, shall be
eligible for benefits under Keystone's severance plan for employees.  Under
Keystone's severance plan, as modified for FFWM employees by the FFWM Plan of
Merger, if within one year after the FFWM Merger the employment of such an
employee is involuntarily terminated through no fault of the employee,

                                      -46-
<PAGE>
 
or voluntarily terminated by the employee within 30 days after being transferred
to a location more than 35 commuting miles from the employee's current job
location, then, in the absence of certain disqualifying events, the employee
will generally be entitled to receive biweekly severance payments in an
aggregate amount equal to one week's base compensation for each year of service
up to a maximum of 26 weeks and to continuation of certain medical and life
insurance benefits during the period of severance payments. If an eligible FFWM
employee is offered a position with Keystone or a subsidiary at an annual base
compensation below that in effect immediately prior to the FFWM Merger, the
employee may elect either to accept the position at the reduced compensation or
to refuse the position and take severance benefits. Severance payments will be
offset by compensation received from subsequent employment during the period of
severance benefits.


Stock Option Agreement

     In connection with the FFWM Plan of Merger, Keystone and FFWM have entered
into a Stock Option Agreement (the "Option Agreement") under which FFWM has
granted Keystone an option (the "Option") to purchase up to 16.6% (after
exercise) of FFWM's outstanding Common Stock upon the occurrence of certain
events described below. The Option Agreement covers 423,600 shares of FFWM
Common Stock at an exercise price of $34.19 per share.

     The Option Agreement is designed to compensate Keystone for its risks,
costs and expenses and the commitment of resources associated with the FFWM Plan
of Merger in the event the FFWM Merger is not consummated due to an attempt by a
third person to gain control of FFWM.  Keystone may not exercise or sell its
Option unless (i) FFWM shall have authorized, recommended or publicly proposed,
or publicly announced an intention to authorize, recommend or propose, or
entered into an agreement with any third person to effect (A) a merger,
consolidation or similar transaction involving FFWM or any of its subsidiaries,
(B) the sale or other disposition of 15% or more of the consolidated assets of
FFWM and its subsidiaries, or (C) the issuance, sale or other disposition of
securities representing 15% or more of the voting power of FFWM or any of its
subsidiaries (any of the foregoing an "Acquisition Transaction"); or (ii) any
third person or group shall have acquired beneficial ownership of or the right
to acquire beneficial ownership of 25% or more of the then outstanding shares of
FFWM Common Stock (each of the foregoing is hereafter referred to as a "Purchase
Event").  No Purchase Event has occurred as of the date of this Joint Proxy
Statement/Prospectus, and neither Keystone nor FFWM is aware that any Purchase
Event is contemplated by any third person.  The Option Agreement may discourage
third persons from making competing offers to acquire FFWM and is intended to
increase the likelihood that the FFWM Merger will be consummated in accordance
with the terms set forth in the FFWM Plan of Merger.

     If a Purchase Event occurs, Keystone may exercise the Option in whole or in
part or may sell or transfer all or part of the Option to other persons.  Under
federal banking law, exercise of the Option by Keystone for more than 5% of the
outstanding FFWM Common Stock would require approval of regulatory authorities.

     Keystone may require FFWM to redeem the Option or any shares of FFWM Common
Stock purchased thereunder if (i) any third person or group shall have acquired
beneficial ownership of or the right to acquire beneficial ownership of 50% or
more of the then outstanding shares of FFWM Common Stock or (ii) FFWM (A)
mergers or consolidates with any third person and is not the surviving
corporation, (B) engages in a merger with a third person in which it is the
surviving corporation but in which the outstanding shares of FFWM Common Stock
are exchanged for other securities, cash or property or after the merger
represent less than 50% of the outstanding shares or (C) sells or transfers more
than 50% of its consolidated assets to any third person (each of the foregoing
is hereafter referred to as a "Redemption Event").  In general, the per share
redemption price for the Option would be excess, if any, over the Option
exercise price of the highest of (i) the highest price paid for any share of
FFWM Common Stock by the person or group acquiring 50% beneficial ownership,
(ii) the price per share received by holders of FFWM Common Stock in connection
with any Redemption Event transaction, or (iii) the highest closing sales price
per share of FFWM Common Stock on the NASDAQ National Market System during the
60 business days preceding the request for redemption.  The per share redemption
price for shares of FFWM Common Stock purchased under the Option would be the
sum of the Option redemption price and the exercise price paid for

                                      -47-
<PAGE>
 
the Option shares. The aggregate amount which FFWM is required to pay in
redeeming the Option or Option shares is limited to $4 million.

     The Option Agreement also contains provisions for issuance of a substitute
Option Agreement to purchase shares of the surviving or acquiring company in the
event of a merger or other acquisition of FFWM or a majority of its assets.

     The foregoing description is intended only as a summary of the material
provisions of the Option Agreement and does not purport to be complete.  It is
qualified in its entirety by reference to the Option Agreement, which has been
filed with the SEC as an exhibit to the Registration Statement.  The Option
Agreement is incorporated in this Joint Proxy Statement/Prospectus by reference
to such filing.


Inconsistent Activities

     FFWM has agreed in the FFWM Plan of Merger that it will not, and will not
permit its subsidiaries to, solicit or encourage inquiries or proposals with
respect to, furnish any information relating to, or participate in any
negotiations or discussions concerning, any acquisition, lease or purchase of
all or a substantial portion of the assets of, or any equity interest in, FFWM
or a subsidiary (other than with Keystone or an affiliate); provided that FFWM's
Board of Directors may furnish such information or participate in such
negotiations or discussions if such Board, after having consulted with and
considered the advice of outside counsel, has determined that the failure to do
so would cause the members of such Board to breach their fiduciary duties under
applicable law.  FFWM is required to promptly inform Keystone of any such
request for information or of any such negotiations or discussions and to
instruct its and its subsidiaries' directors, officers, representatives and
agents to refrain from taking any action prohibited by these provisions.


Conduct of Business Pending the FFWM Merger

     FFWM has agreed in the FFWM Plan of Merger that pending consummation of the
FFWM Merger, except as consented to by Keystone, FFWM and its subsidiaries will
conduct their business only in the ordinary course consistent with past practice
and will not, among other things, (i) issue any shares of their capital stock or
grant any options or other rights to acquire such stock, except pursuant to the
Option Agreement or existing employee and director stock options, purchase any
FFWM Common Stock or effect any recapitalization, stock dividend or split; (ii)
amend their charter documents, suffer any lien on FFWM's ownership of its
subsidiaries or waive or compromise any material right or claim; (iii) make
certain changes in the compensation or benefits payable to employees and
directors; (iv) enter into any transaction or agreement not in the ordinary
course of business, certain borrowing arrangements or employment or labor
contracts; (v) make voluntary changes in their accounting methods or tax
reporting, (vi) make capital expenditures or lease assets in excess of certain
limits; (vii) take certain actions with respect to branching; (viii) acquire
control over or make equity investments exceeding 5% in any business; (ix) enter
into interest-hedging agreements; (x) enter into any agreement granting a
preferential right to purchase any of their assets or rights or requiring
consent for their transfer; (xi) make material changes to their lending or
investment policies; or (xii) take any action which would prevent or impede the
FFWM Merger from qualifying as a reorganization within the meaning of Section
368 of the Internal Revenue Code.

     Keystone has agreed that except as consented to by FFWM it will not (i)
amend its charter documents or those of a significant subsidiary in a manner
which would adversely affect the terms of the Keystone Common Stock or the
ability of Keystone and American Trust Bank to consummate the FFWM Merger and
the Bank Merger, (ii) make any acquisition, enter into any agreement or
transaction or take any other action that could materially adversely affect the
ability of Keystone and American Trust Bank to consummate the FFWM Merger and
the Bank Merger, (iii) declare or pay any dividend or distribution in respect of
the Keystone Common Stock other than regular quarterly cash dividends in an
amount determined by Keystone's Board of Directors in the ordinary course of
business and consistent with past practice or (iv) take any action, other than
the exercise of its

                                      -48-
<PAGE>
 
rights under the Option Agreement, which would prevent or impede the FFWM Merger
from qualifying as a reorganization within the meaning of Section 368 of the
Internal Revenue Code.


FFWM Dividend Limitation

     FFWM has agreed in the FFWM Plan of Merger that pending the FFWM Merger it
will not increase the rate of dividends on the FFWM Common Stock to exceed $.12
per share in any calendar quarter.  Beginning in the quarter ended December 31,
1995, dividends on the FFWM Common Stock have been paid at the rate of $.12 per
share.  See "Information Concerning FFWM--Stock Prices and Dividends of FFWM
Common Stock."


Conditions to the FFWM Merger

     In addition to approval by the shareholders of FFWM, the FFWM Merger is
contingent upon the satisfaction of a number of other conditions, including (i)
receipt of regulatory approvals required for the consummation of the FFWM Merger
and the Bank Merger and the expiration or all statutory waiting periods in
connection therewith, (ii)  the absence of any statute, rule or governmental or
judicial injunction, order or decree which prohibits or restricts consummation
of the FFWM Merger or the Bank Merger and (iii) receipt of the tax opinion
described above (see "Tax Consequences to FFWM Shareholders").  In addition,
unless waived, each party's obligation to consummate the FFWM Merger is subject
to the performance by the other party of its obligations under the FFWM Plan of
Merger, the accuracy of the representations and warranties of the other party
contained therein, the receipt of certain certificates and opinions from the
other party and the absence of any pending proceeding initiated by a
governmental authority seeking to prevent consummation of the FFWM Merger or the
Bank Merger.  If the Distribution Date under Keystone's shareholder rights plan
(see "Comparison of Keystone Common Stock and FFWM Common Stock--Keystone
Shareholder Rights Plan") shall have occurred, then either (i) all Rights
outstanding under the plan (other than those which have become void) shall have
been exchanged for Keystone Common Stock and the Exchange Ratio shall have been
proportionately adjusted as provided in the FFWM Plan of Merger, (ii) all Rights
outstanding under the plan shall have been redeemed or (iii) Keystone shall have
made provision for the issuance of equivalent rights to the holders of FFWM
Common Stock upon consummation of the FFWM Merger.


Representations and Warranties

     The representations and warranties of Keystone and FFWM contained in the
FFWM Plan of Merger relate, among other things, to the organization and good
standing of FFWM, Keystone and their subsidiaries; the capitalization of FFWM
and Keystone and the ownership of their subsidiaries; the authorization by
Keystone and FFWM of the FFWM Plan of Merger and the absence of conflict with
laws or other agreements; the accuracy and completeness of the financial
statements and other information furnished to the other party; the absence of
material adverse changes since September 30, 1996; payment of taxes; the absence
of undisclosed litigation; compliance with laws; insurance; and the accuracy of
this Joint Proxy Statement/Prospectus and of Keystone's Registration Statement
of which it is a part.  Additional representations and warranties by FFWM
concern the absence of certain potential environmental liabilities; the absence
of undisclosed equity investments; the absence of undisclosed employment
contracts, employee benefit plans or material contracts or material defaults
thereunder; title to properties; and labor relations.  None of the
representations and warranties contained in the FFWM Plan of Merger will survive
the consummation of the FFWM Merger.


Amendment, Waiver and Termination

     Notwithstanding prior approval by the shareholders of FFWM, the FFWM Plan
of Merger may be amended in any respect by written agreement between the
parties, except that after such shareholder approval no amendment or waiver of
any provision of the FFWM Plan of Merger may change the amount or form of the

                                      -49-
<PAGE>
 
consideration to be received by the holders of FFWM Common Stock in the FFWM
Merger or otherwise materially adversely affect the FFWM shareholders without
the approval of the shareholders so affected.  Keystone or FFWM may also (i)
extend the time for performance of any of the obligations of the other; (ii)
waive any inaccuracies in the representations and warranties of the other; (iii)
waive compliance by the other with any of its obligations under the FFWM Plan of
Merger; and (iv) waive any condition precedent to its obligations under the FFWM
Plan of Merger other than approval of the FFWM Plan of Merger by the
shareholders of FFWM, governmental regulatory approvals required to consummate
the FFWM Merger, securities registration requirements incident to the issuance
of Keystone Common Stock in the FFWM Merger, and the absence of any judicial or
administrative order prohibiting the FFWM Merger.

     Notwithstanding prior shareholder approval, the FFWM Plan of Merger may be
terminated at any time prior to effectiveness of the FFWM Merger (a) by mutual
consent of Keystone and FFWM or (b) by either party (1) in the event of a breach
by the other party of a representation and warranty or covenant which would have
a material adverse effect on the breaching party or on the ability of the
parties to consummate the transactions contemplated by the FFWM Plan of Merger
and which has not been cured within 30 days after notice to the breaching party,
(2) if a court or regulatory authority has issued a final and nonappealable
order enjoining or prohibiting consummation of the FFWM Merger or the Bank
Merger or (3) if other than as a result of a failure of the terminating party to
perform its obligations under the FFWM Plan of Merger (A) an application for a
regulatory approval required to consummate the FFWM Merger or the Bank Merger is
finally denied or withdrawn at the request of the regulatory agency, (B)  the
shareholders of FFWM do not approve the FFWM Plan of Merger at the FFWM Special
Meeting or any adjournment thereof or (C) the FFWM Merger has not become
effective on or prior to November 26, 1997.

     The FFWM Plan of Merger may also be terminated (a) by FFWM if the average
of the closing bid prices for Keystone Common Stock on the NASDAQ National
Market System for the 20 consecutive trading days ending with the date of
approval of the Bank Merger by the OCC (the "Measurement Price") is less than
$21.20 per share or (b) by Keystone if the Measurement Price is greater than
$31.80 per share.  If the FFWM Plan of Merger is terminated by Keystone pursuant
to this provision, FFWM may within five days thereafter elect to decrease the
exchange ratio of 1.29 shares of Keystone Common Stock for each FFWM share to a
number (calculated to the nearest one-thousandth) obtained by dividing $41.02 by
the Measurement Price.  If FFWM makes this election, then Keystone's termination
pursuant to this provision shall be deemed rescinded and the FFWM Plan of Merger
shall remain in effect in accordance with its terms (except as the Exchange
Ratio shall have been so modified).  On February ___, 1997 the closing bid
price for Keystone Common Stock on the NASDAQ National Market System was $_____.


Termination Fee

     The FFWM Plan of Merger provides that if either party terminates the FFWM
Plan of Merger due to a pending proceeding initiated by a governmental authority
seeking to prevent consummation of the FFWM Merger or the Bank Merger or because
an application for a regulatory approval required to consummate the FFWM Merger
or the Bank Merger is finally denied or withdrawn at the request of the
regulatory agency, Keystone will pay to FFWM a termination fee of $1,000,000.
If within three years from the date of such termination, FFWM or any of its
subsidiaries enters into an agreement providing for (a) the merger or
consolidation of FFWM or any of its subsidiaries with any third person, (b) the
disposition to any third person or persons in one or a series of related
transactions not in the ordinary course of business of assets or deposits
representing 15% or more of the consolidated assets or deposits of FFWM or (c)
the issuance, sale, transfer or other disposition to any one person (including
its affiliates or associates) of securities representing 15% or more of the
voting power of FFWM or any of its subsidiaries, FFWM must repay such amount to
Keystone without interest.

Dissenters' Rights of FFWM Shareholders

     A record holder of shares of FFWM Common Stock is entitled to exercise the
rights of a dissenting shareholder under Section 262 of the Delaware General
Corporation Law, as amended ("Section 262"), to object to the FFWM Plan of
Merger and make written demand that Keystone, as the surviving corporation in
the FFWM Merger, pay in cash the appraised value of the shares held as
determined in accordance with Section 262. The following summary does not
purport to be a complete statement of the provisions of Section 262 and is
qualified in its entirety by reference to Section 262, the complete text of
which is set forth as Annex IV to this Joint Proxy Statement/Prospectus.

     A beneficial owner of shares of FFWM Common Stock who is not the record
holder of such shares is not entitled to exercise dissenters' rights directly,
but instead must request the record holder of the shares to exercise such rights
on his or her behalf.  A beneficial owner wishing to exercise such rights should
contact the record holder promptly and assure that the record holder complies
with all of the statutory provisions and procedures summarized herein.

     If a record holder of shares of FFWM Common Stock (a "holder") wishes to
dissent from the FFWM Plan of Merger and obtain payment of the appraised value
of the holder's shares, he or she must satisfy all of the following conditions
in order to obtain any right to payment of the appraised value of the shares
under Section 262:

          (1) The holder must deliver to FFWM, before the taking of the vote on
     the FFWM Plan of Merger, a written demand for appraisal of the holder's
     shares. Such demand will be sufficient if it reasonably informs FFWM of the
     identity of the holder and that the holder intends thereby to demand the
     appraisal of the holder's shares. A proxy or vote against the FFWM Plan of
     Merger shall not constitute such a demand. A holder electing to take such
     action must do so by separate written demand as provided in Section 262.

          (2)  The holder must hold of record the shares as to which appraisal
     is demanded on the date of making such written demand and continuously
     thereafter through the effective date of the FFWM Merger.

          (3)  The holder must not vote the shares in favor of the FFWM Plan of
     Merger.  Neither an abstention from voting with respect to, nor failure to
     vote in person or by proxy against approval of the FFWM Plan of Merger
     constitutes a waiver of the rights of a dissenting shareholder.  However, a
     signed proxy card that is returned without any instruction as to how the
     proxy should be voted will be voted in favor of approval of the FFWM Plan
     of Merger and will be deemed a waiver of the rights of a dissenting
     shareholder.

     A dissenter who fails in any of these respects will not acquire any right
to payment of the appraised value of the holders shares under Section 262.  Each
written demand for appraisal should clearly state that the holder intends
thereby to demand the appraisal of the holders shares, should provide the name,
address and telephone number of the holder and the number of shares of FFWM
Common Stock held of record by the holder as to which appraisal is demanded and
should be sent to First Financial Corporation of Western Maryland, 118 Baltimore
Street, Cumberland, Maryland 21502, Attention:  William C. Marsh, Executive Vice
President and Chief Financial Officer.

     Within 10 days after the effective date of the FFWM Merger, Keystone shall
notify each holder of FFWM Common Stock who has complied with the requirements
of Section 262 and who has not voted in favor of the FFWM Plan of Merger of the
date that the FFWM Merger has become effective.

     Within 120 days after the effective date of the FFWM Merger, Keystone or
any holder who has complied with the requirements of Section 262 and who is
otherwise entitled to appraisal rights, may file a petition in the Delaware
Court of Chancery demanding a determination of the value of the stock of all
such holders. Notwithstanding the foregoing, at any time within 60 days after
the effective date of the FFWM Merger, any holder

                                      -51-
<PAGE>
 
shall have the right to withdraw the holder's demand for appraisal and to accept
the terms offered in the FFWM Plan of Merger. Within 120 days after the
effective date of the FFWM Merger, any holder who has complied with the
requirements of Section 262, upon written request, shall be entitled to receive
from Keystone a statement setting forth the aggregate number of shares not voted
in favor of the FFWM Merger and with respect to which demands for appraisal have
been received and the aggregate number of holders of such shares. Such written
statement shall be mailed to the holder within 10 days after his written request
for such a statement is received by Keystone or within 10 days after expiration
of the period for delivery of demands for appraisal, whichever is later.

     Upon the filing of any such petition by a holder, service of a copy thereof
shall be made upon Keystone, which shall within 20 days after such service file
in the office of the Register in Chancery in which the petition was filed a duly
verified list containing the names and addresses of all holders who have
demanded payment for their shares and with whom agreements as to the value of
their shares have not been reached by Keystone.  If the petition is filed by
Keystone, it shall be accompanied by such a duly verified list.  The Register in
Chancery, if so ordered by the Court, shall give notice of the time and place
fixed for the hearing of such petition by registered or certified mail to
Keystone and to the holders shown on the list at the addresses therein stated.
Such notice shall also be given by one or more publications at least one week
before the day of the hearing, in a newspaper of general circulation published
in Wilmington, Delaware or such publication as the Court deems advisable.  The
forms of the notices by mail and by publication shall be approved by the Court,
and the costs thereof shall be approved by the Court and shall be borne by
Keystone.

     At the hearing on such petition, the Court shall determine the holders who
have complied with Section 262 and who have become entitled to appraisal rights.
The Court may require the holders who have demanded an appraisal for their
shares to submit their FFWM Common Stock certificates to the Register in
Chancery for notation thereon of the pendency of the appraisal proceedings; and
if any holder fails to comply with such direction, the Court may dismiss the
proceedings as to such holder.

     After determining the holders entitled to an appraisal, the Court shall
appraise the shares, determining their fair value exclusive of any element of
value arising from the accomplishment or expectation of the FFWM Merger,
together with a fair rate of interest, if any, to be paid upon the amount
determined to be the fair value.  In determining such fair value, the Court
shall take into account all relevant factors.  In determining the fair rate of
interest, the Court may consider all relevant factors, including the rate of
interest which Keystone would have had to pay to borrow money during the
pendency of the proceeding.  Upon application by Keystone or by any holder
entitled to participate in the appraisal proceeding, the Court may, in its
discretion, permit discovery or other pretrial proceedings and may proceed to
trial upon the appraisal prior to the final determination of the holders
entitled to an appraisal.  Any holder whose name appears on the list filed by
Keystone and who has submitted his FFWM Common Stock certificates to the
Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to appraisal
rights under Section 262.

     The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by Keystone to the holders entitled thereto.
Interest may be simple or compound, as the Court may direct.  Payment shall be
so made to each such holder upon the surrender to Keystone of the FFWM Common
Stock certificates representing such stock.  The Court's decree may be enforced
as other decrees in the Court of Chancery may be enforced, notwithstanding that
Keystone is not a Delaware corporation.

     The costs of the proceeding may be determined by the Court and taxed upon
the parties as the Court deems equitable in the circumstances.  Upon application
of a holder, the Court may order all or a portion of the expenses incurred by
any holder in connection with the appraisal proceeding, including, without
limitation, reasonable attorney's fees and the fees and expenses of experts,
to be charged pro rata against the value of all the shares entitled to an
appraisal.

     From and after the effective date of the FFWM Merger, no holder of FFWM
Common Stock who has demanded appraisal rights shall be entitled to vote such
stock for any purpose or to receive payment of dividends or other distributions
on the stock (except dividends or other distributions payable to shareholders of
record at a date which is prior to the effective date of the FFWM Merger);
provided, however, that if no petition for an appraisal

                                      -52-
<PAGE>
 
shall be filed within the time required by Section 262, or if such holder shall
deliver to Keystone a written withdrawal of the holder's demand for an appraisal
and an acceptance of the FFWM Merger, either within 60 days after the effective
date of the FFWM Merger or thereafter with the written approval of Keystone,
then the right of such holder to an appraisal shall cease. Notwithstanding the
foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed
as to any holder without the approval of the Court, and such approval may be
conditioned upon such terms as the Court deems just.

     FFWM SHAREHOLDERS WISHING TO EXERCISE DISSENTERS' RIGHTS ARE ADVISED TO
CONSULT THEIR OWN COUNSEL TO ENSURE THAT THEY FULLY AND PROPERLY COMPLY WITH THE
REQUIREMENTS OF SECTION 262.


Restrictions on Resales by FFWM Affiliates

     The shares of Keystone Common Stock issuable in the FFWM Merger have been
registered under the Securities Act, and such shares will generally be freely
tradable by the FFWM shareholders who receive Keystone shares as a result of the
FFWM Merger.  However, this registration does not cover resales by FFWM
shareholders who may be deemed to control or be under common control with FFWM
and who therefore may be deemed "affiliates" of FFWM as that term is defined in
Rule 145 under the Securities Act.  Such affiliates may not sell their shares of
Keystone Common Stock acquired in the FFWM Merger except pursuant to:  (i) an
effective Registration Statement under the Securities Act covering the shares to
be sold; (ii) the conditions contemplated by Rules 144 and 145 under the
Securities Act; or (iii) another applicable exemption from the registration
requirements of the Securities Act.  The management of FFWM will notify those
persons whom it believes may be such affiliates.


Effect on FFWM's Dividend Reinvestment Plan

     FFWM's Dividend Reinvestment Plan will be terminated [as of the last FFWM
dividend payment date preceding the effective date of the FFWM Merger].
Following the FFWM Merger, FFWM shareholders who become Keystone shareholders
will be able to participate in a Dividend Reinvestment Plan offered by Keystone.


Expenses

     Keystone will pay 75% and FFWM will pay 25% of the expenses of printing the
Registration Statement, and Keystone and FFWM will each pay 50% the portion of
registration fee relating to the FFWM Merger to be paid to the SEC in connection
therewith.  Each party will pay its own other expenses incurred in connection
with the FFWM Plan of Merger.


Accounting Treatment

     The FFWM Merger will be accounted for under the purchase method of
accounting.  The assets and liabilities of FFWM acquired in the FFWM Merger will
be recorded by Keystone for financial reporting purposes at their market values
as of the date of the FFWM Merger, and any excess of the consideration paid over
the net market values acquired will be recorded and amortized as goodwill.


Effective Date of the FFWM Merger

     It is presently anticipated that if the FFWM Plan of Merger is approved by
the shareholders of FFWM, the FFWM Merger will become effective in the second
quarter of 1997.  However, as noted above, consummation of the FFWM Merger is
subject to the satisfaction of a number of conditions, some of which cannot be
waived.  There can be no assurance that all conditions to the FFWM Merger will
be satisfied or, if satisfied, that they will be

                                      -53-
<PAGE>
 
satisfied in time to permit the FFWM Merger to become effective within the
anticipated time frame. In addition, as also noted above, Keystone and FFWM
retain the power to abandon the FFWM Merger or to extend the time for
performance of conditions or obligations necessary to its consummation,
notwithstanding prior shareholder approval.

            COMPARISON OF KEYSTONE COMMON STOCK AND FTC COMMON STOCK

General

     Upon consummation of the Merger, shareholders of FTC will become
shareholders of Keystone.  Since the Articles of Incorporation ("Articles") and
Bylaws of Keystone and FTC are not the same, the Merger will result in certain
changes in the rights of the holders of FTC Common Stock.  These changes are
discussed below.


Voting Rights

     General.  The holders of Keystone Common Stock, like the holders of FTC
Common Stock, are generally entitled to one vote for each share held of record
on all matters submitted to a shareholder vote and do not have cumulative voting
rights in the election of directors.  The absence of cumulative voting means
that a nominee for director must receive the votes of a plurality of the shares
voted in order to be elected.

     Special Votes for Certain Transactions.  The Articles of Keystone and FTC
contain provisions requiring special shareholder votes to approve certain types
of transactions.  In the absence of these provisions, either the transactions
would require approval by a majority of the shares voted at a meeting or no
shareholder vote would be required.

     Keystone's Articles require that certain transactions between Keystone or a
subsidiary and an "interested shareholder" be approved by the votes of the
holders of (1) 75% of the voting power of all outstanding voting stock of
Keystone and (2) a majority of the voting power of the voting stock not
beneficially owned by the interested shareholder.  An "interested shareholder"
is generally defined by Keystone's Articles to mean a person or a group acting
in concert that beneficially owns more than 20% of the voting power of
Keystone's outstanding voting stock.

     The transactions subject to Keystone's special vote requirements include
(1) a merger, consolidation or share exchange of Keystone or a subsidiary with
an interested shareholder, (2) the sale, lease, exchange or other disposition,
or the loan, mortgage, pledge or investment, by Keystone or a subsidiary of 5%
or more of Keystone's assets to, with or for the benefit of an interested
shareholder, (3) the issuance or transfer to an interested shareholder of
securities of Keystone or a subsidiary valued at 5% or more of Keystone's
consolidated total assets, (4) the adoption of any plan for the liquidation of
Keystone proposed by or on behalf of an interested shareholder, (5) any
reclassification of securities, recapitalization of Keystone, merger or
consolidation of Keystone with a subsidiary or other transaction which increases
the percentage of any class of stock of Keystone or a subsidiary owned by an
interested shareholder and (6) any other transaction which is similar in purpose
or effect to the foregoing.

     Keystone's special shareholder vote requirements do not apply to any
transaction approved by a majority of the "disinterested directors."  A
disinterested director is any member of the Keystone Board who is not an
interested shareholder or an affiliate, associate or representative of an
interested shareholder and who (1) was a director before the interested
shareholder became an interested shareholder or (2) is a successor to a
disinterested director and was recommended for election by a majority of the
disinterested directors then on the Board.

     FTC's Articles require that certain transactions involving FTC be approved
by the vote of the holders of at least two-thirds of the outstanding shares of
FTC Common Stock.  The transactions subject to FTC's special voting requirements
are a merger or consolidation of FTC with another corporation or the sale, lease
or exchange of all or substantially all of the assets of FTC.

Board of Directors

     Classified Boards.  The Articles of Keystone and the Bylaws of FTC divide
the Board of Directors into three classes, each consisting of one-third (or as
near as may be) of the whole number of the Board of Directors.  One class of
directors is elected at each Annual Meeting of Shareholders, and each class
serves for a term of three years.

     The number of directors which constitute the full Board of Directors of
Keystone may be increased or decreased only by the Board of Directors, by a vote
including a majority of the disinterested directors then in office, and except
as otherwise required by law, vacancies on the Board of Directors of Keystone,
including vacancies resulting from an increase in the size of the Board, may be
filled only by the Board of Directors by a similar vote.  Directors elected by
the Board to fill vacancies serve for the full remainder of the term of the
class to which they have been elected.

     FTC's Bylaws provide that FTC's Board of Directors shall consist of such
number of directors, not less than five, as the Board may determine.  Vacancies
on the FTC Board, including vacancies resulting from an increase in the number
of directors, may be filled by a majority of the Board.  Directors elected by
the Board to fill vacancies serve only until the next annual meeting of
shareholders or until an earlier special meeting called to elect directors.  The
shareholders of FTC can also change the number of FTC directors by amending the
Bylaws in accordance with the provisions described below and may at the same
meeting elect directors to fill any vacancies created by an increase in the size
of the Board.

     Removal of Directors.  Keystone's Articles provide that a director, any
class of directors or the entire Board of Directors may be removed from office
by shareholder vote only for cause and only if, in addition to any other vote
required by law, such removal is approved by a majority of the voting power of
the outstanding voting stock of Keystone which is not beneficially owned by an
interested shareholder.

     FTC's Articles and Bylaws are silent as to removal of directors.  Under the
Pennsylvania Business Corporation Law ("BCL"), because FTC has a shareholder-
adopted classified Board, the entire Board, any class of directors or any
individual director may be removed from office only for cause by a majority of
the votes cast at a meeting of the FTC shareholders.  In addition, the entire
Board may be removed from office with or without cause by the unanimous vote or
consent of the holders of FTC Common Stock.

     Nomination of Director Candidates.  The Articles of Keystone and the Bylaws
of FTC require that any shareholder intending to nominate a candidate for
election as a director must give the corporation advance written notice of the
nomination, containing certain specified information.  Keystone's Articles
require that the notice be given not later than 120 days in advance of the
meeting at which the election is to be held.  FTC's Articles require the notice
to be given not less than 14 or more than 50 days prior to the meeting at which
the election is to be held, except that if less than 21 days notice of the
meeting is given by FTC, the notice may be given within seven days after the
notice of the meeting was mailed.


Amendment of Articles and Bylaws

     Keystone's Articles require the votes of the holders of (1) 75% of the
voting power of all outstanding voting stock of Keystone and (2) a majority of
the voting power of the voting stock not beneficially owned by an interested
shareholder to approve any amendment to Keystone's Articles or Bylaws.  The
special voting requirement does not apply to any amendment approved by a
majority of the disinterested directors if at the time of such approval the
disinterested directors constitute a majority of Keystone's Board.  Except as to
matters for which a shareholder vote is required by statute, Keystone's Board
may also amend the Bylaws without shareholder approval by a vote including a
majority of the disinterested directors then in office.

     FTC's Articles require the vote of the holders of at least two-thirds of
the outstanding FTC Common Stock to amend the special shareholder vote
provisions described above under "Voting Rights--Special Votes for Certain

                                      -60-
<PAGE>
 
Transactions."  Under applicable provisions of the BCL, the other provisions of
FTC's Articles may be amended by a majority of the votes cast at a meeting of
FTC shareholders.  However, in order to be deemed to be adopted by FTC, any
Articles amendment adopted by the shareholders must also be approved by Board of
Directors.

     Under the BCL, FTC's Bylaws may be amended by the shareholders at any
annual or special meeting by a majority of the votes cast on the proposal.
Except as to matters for which a shareholder vote is required by statute, FTC's
Bylaws may also be amended by the vote of a majority of the Board of Directors,
subject to the power of the shareholders to change such action, except that the
Board may not adopt amendments fixing their qualifications, classification or
term of office.


Keystone Shareholder Rights Plan

     Keystone has established a shareholder rights plan under which each share
of Keystone Common Stock presently outstanding or which is issued hereafter
prior to the Distribution Date (defined below) is granted one preferred share
purchase right (a "Right").  Each Right entitles the registered holder to
purchase from Keystone 5.333 one-thousandths (0.005333) of a share of Series A
Junior Participating Preferred Stock, par value $1.00 per share (the "Preferred
Shares"), of Keystone at a price of $56.00 per 5.333 one-thousandths of a
Preferred Share, subject to adjustment in the event of stock dividends and
similar events occurring prior to the Distribution Date.  Each 5.333 one-
thousandths of a Preferred Share would have voting, dividend and liquidation
rights which are the approximate equivalent of one share of Keystone Common
Stock.

     The Rights are not exercisable until the Distribution Date, which is the
earlier to occur of (i) 10 days following a public announcement that a person or
group (an "Acquiring Person") has acquired beneficial ownership of 20% or more
of the outstanding Keystone Common Stock or (ii) 10 business days (unless
extended by the Board of Directors prior to any person or group becoming an
Acquiring Person) following the commencement of, or announcement of an intention
to make, a tender offer or exchange offer the consummation of which would result
in the beneficial ownership by a person or group of 20% or more of the
outstanding Keystone Common Stock.

     Until the Distribution Date, the Rights will be transferred with and only
with Keystone Common Stock, and the surrender for transfer of any certificate
for Keystone Common Stock will also constitute the transfer of the Rights
associated with the shares represented by such certificate.  As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights will be mailed to holders of record of Keystone Common Stock as of
the close of business on the Distribution Date, and the Rights will then become
separately tradable.

     In the event that any person becomes an Acquiring Person, each holder of a
Right, other than Rights beneficially owned by the Acquiring Person or its
associates or affiliates (which will be void), will thereafter have the right to
receive upon exercise that number of Common Shares or, at the option of
Keystone, Preferred Shares (or shares of a class or series of Keystone's
preferred stock having equivalent rights, preferences and privileges) or, in
certain circumstances, other securities or assets, having a market value of two
times the exercise price of the Right.  In the event that after the first public
announcement that any person has become an Acquiring Person, Keystone is
acquired in a merger or other business  combination transaction or 50% or more
of its consolidated assets or earning power are sold, proper provision will be
made so that each holder of a Right, other than rights beneficially owned by the
Acquiring Person or its associates or affiliates (which will be void) will
thereafter have the right to receive, upon exercise of the Right, that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times the exercise price of the
Right.

     At any time after the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding Keystone Common Stock and prior to
the acquisition by such person or group of 50% or more of the outstanding
Keystone Common Stock, the Board of Directors may exchange the Rights (other
than Rights owned by such person or group, which have become void), in whole or
in part, at an exchange ratio of one share of Keystone Common Stock, or 5.333
one-thousandths of a Preferred Share (or of a share of a class or series of

                                      -61-
<PAGE>
 
Keystone's preferred stock having equivalent rights, preferences and
privileges), or, in certain circumstances, an amount of other securities or
assets having equivalent value, per Right (subject to adjustment).

     At any time prior to the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding Keystone Common Stock, the Board of
Directors may redeem the Rights in whole, but not in part, at a price of $.01
per Right.

     The terms of the Rights may be amended by the Board of Directors without
the consent of the holders of the Rights before the Distribution Date in any
respect whatever, except for an amendment that would reduce the redemption
price.  Prior to any person becoming an Acquiring Person, Keystone may without
the consent of the holders of the Rights lower the 20% thresholds referred to
above to not less than the greater of (i) any percentage greater than the
largest percentage of the outstanding Keystone Common Stock then known to
Keystone to be beneficially owned by any person or group of affiliated or
associated persons and (ii) 10%.  The Rights will expire on February 8, 2000,
unless the expiration date is extended or unless the Rights are earlier redeemed
by Keystone as described above.


Pennsylvania Business Corporation Law

     The provisions of Keystone's and FTC's Articles and Bylaws described under
"Voting Rights" and "Board of Directors" above and Keystone's shareholder rights
plan are in addition to certain provisions of Chapter 25 of the BCL which may
have the effect of discouraging or rendering more difficult a hostile takeover
attempt against Keystone or FTC.

     Under Section 2538 of the BCL, any merger, consolidation, share exchange or
sale of assets between Keystone or FTC or their subsidiary and any shareholder
of the corporation, any division of Keystone or FTC in which any shareholder
receives a disproportionate amount of any shares or other securities of any
corporation resulting from the division, any voluntary dissolution of Keystone
or FTC in which a shareholder is treated differently from other shareholders of
the same class or any reclassification in which any Keystone or FTC
shareholder's voting or economic interest in the corporation is materially
increased relative to substantially all other shareholders must, in addition to
any other shareholder vote required, be approved by a majority of the votes
which all shareholders other than the shareholder receiving the special
treatment are entitled to cast with respect to the transaction.  This special
vote requirement does not apply to a transaction (1) which has been approved by
a majority vote of the Board, without counting the vote of certain directors
affiliated with or nominated by the interested shareholder or (2) in which the
consideration to be received by the shareholders is not less than the highest
amount paid by the interested shareholder in acquiring shares of the same class.

     Under Subchapter 25E of the BCL, if any person or group acting in concert
acquires voting power over Keystone or FTC shares representing 20% or more of
the votes which all shareholders of the corporation would be entitled to cast in
an election of directors, any other shareholder may demand that such person or
group purchase such shareholder's shares at a price determined in an appraisal
proceeding.

     Under Subchapter 25G of the BCL, Keystone or FTC may not engage in merger,
consolidation, share exchange, division, asset sale or a variety of other
"business combination" transactions with a person which becomes the "beneficial
owner" of shares representing 20% or more of the voting power in an election of
directors of the corporation unless (1) the business combination or the
acquisition of the 20% interest is approved by the Board of Directors of the
corporation prior to the date the 20% interest is acquired, (2) the person
beneficially owns at least 80% of the outstanding shares and the business
combination (a) is approved by a majority vote of the disinterested shareholders
and (b) satisfies certain minimum price and other conditions prescribed in
Subchapter 25F, (3) the business combination is approved by a majority vote of
the disinterested shareholders at a meeting called no earlier than five years
after the date the 20% interest is acquired or (4) the business combination (a)
is approved by shareholder vote at a meeting called no earlier than five years
after the date the 20% interest is acquired and (b) satisfies certain minimum
price and other conditions prescribed in Subchapter 25F.

                                      -62-
<PAGE>
 
     Keystone has elected to opt out from coverage by Subchapter 25G of the BCL,
which would have required a shareholder vote to accord voting rights to control
shares acquired by a 20% shareholder in a control-share acquisition, and
Subchapter 25H of the BCL, which would have required a person or group to
disgorge to Keystone any profits received from a sale of Keystone's equity
securities within 18 months after the person or group acquired or offered to
acquire 20% of Keystone's voting power or publicly disclosed an intention to
acquire control of Keystone.  FTC has not elected to opt out from coverage by
Subchapters 25G or 25H and is subject to these provisions.


Preferred Stock

     FTC's Articles do not authorize any class of stock other than FTC Common
Stock.  The Articles of Keystone authorize Keystone to issue up to 8,000,000
shares of Keystone preferred stock.

     The authorized shares of Keystone preferred stock are issuable in one or
more series on the terms set by the resolution or resolutions of Keystone's
Board of Directors providing for the issuance thereof.  Each series of preferred
stock would have such dividend rate, which might or might not be cumulative,
such voting rights, which might be general or special, and such liquidation
preferences, redemption and sinking funds provisions, conversion rights or other
rights and preferences, if any, as Keystone's Board of Directors may determine.
Except for such rights as may be granted to the holders of any series of
preferred stock in the resolution establishing such series or as required by
law, all of the voting and other rights of the shareholders of Keystone belong
exclusively to the holders of Keystone Common Stock.


Dividend Rights

     The holders of FTC Common Stock and Keystone Common Stock are entitled to
dividends when, as and if declared by their Board of Directors out of funds
legally available therefor.  However, if Keystone preferred stock is issued, the
Board of Directors of Keystone may grant preferential dividend rights to the
holders of such stock which would prohibit payment of dividends on the Keystone
Common Stock unless and until specified dividends on the preferred stock had
been paid.


Liquidation Rights

     Upon liquidation, dissolution or winding up of Keystone or FTC, whether
voluntary or involuntary, the holders of Keystone or FTC Common Stock are
entitled to share ratably in the assets of the corporation available for
distribution after all liabilities of the corporation have been satisfied.
However, if preferred stock is issued by Keystone, the Board of Directors of
Keystone may grant preferential liquidation rights to the holders of such stock
which would entitle them to be paid out of the assets of the corporation
available for distribution before any distribution is made to the holders of
Keystone Common Stock.


Miscellaneous

     There are no preemptive rights, sinking fund provisions, conversion rights,
or redemption provisions applicable to Keystone or FTC Common Stock.  Holders of
fully paid shares of Keystone or FTC Common Stock are not subject to any
liability for further calls or assessments.

           COMPARISON OF KEYSTONE COMMON STOCK AND FFWM COMMON STOCK

General

     FFWM is a Delaware corporation and, as such, is governed by Delaware
General Corporation Law ("GCL"). As a result of the FFWM Merger, shareholders of
FFWM who make or are deemed to have made the Stock Election will become
shareholders of Keystone. Keystone is a Pennsylvania business corporation and,
as such, the rights of Keystone's shareholders are governed by the Pennsylvania
Business Corporation Law ("BCL"). Differences between the rights of FFWM
shareholders and the rights of Keystone shareholders will arise from this change
of applicable statute as well as from differences between the Certificate of
Incorporation ("Certificate") and Bylaws of FFWM and the Articles of
Incorporation ("Articles") and Bylaws of Keystone. These differences are
described below.


Voting Rights

     General.  The holders of Keystone Common Stock, like the holders of FFWM
Common Stock, are generally entitled to one vote for each share held of record
on all matters submitted to a shareholder vote and do not have cumulative voting
rights in the election of directors.  The absence of cumulative voting means
that a nominee for director must receive the votes of a plurality of the shares
voted in order to be elected.

     Special Votes for Certain Transactions. Both Keystone's Articles and FFWM's
Certificate contain provisions requiring special shareholder votes to approve
certain types of transactions. In the absence of these provisions, either no
shareholder vote would be required or, in the case of Keystone, the BCL would
require approval of the transaction by a majority of the shares Keystone Common
Stock voted at a meeting, and in the case of FFWM, the GCL would require
approval of the transaction by either a majority of the outstanding shares of
FFWM Common Stock or a majority of the shares of FFWM Common Stock represented
at a meeting and entitled to vote.

     Keystone's Articles require that certain transactions between Keystone or a
subsidiary and an "interested shareholder" be approved by the votes of the
holders of (1) 75% of the voting power of all outstanding voting stock of
Keystone and (2) a majority of the voting power of the voting stock not
beneficially owned by the interested shareholder.  An "interested shareholder"
is generally defined by Keystone's Articles to mean a person or a group acting
in concert that beneficially owns more than 20% of the voting power of
Keystone's outstanding voting stock.

     The transactions subject to Keystone's special vote requirements include
(1) a merger, consolidation or share exchange of Keystone or a subsidiary with
an interested shareholder, (2) the sale, lease, exchange or other disposition,
or the loan, mortgage, pledge or investment, by Keystone or a subsidiary of 5%
or more of Keystone's assets to, with or for the benefit of an interested
shareholder, (3) the issuance or transfer to an interested shareholder of
securities of Keystone or a subsidiary valued at 5% or more of Keystone's
consolidated total assets, (4) the adoption of any plan for the liquidation of
Keystone proposed by or on behalf of an interested shareholder, (5) any
reclassification of securities, recapitalization of Keystone, merger or
consolidation of Keystone with a subsidiary or other transaction which increases
the percentage of any class of stock of Keystone or a subsidiary owned by an
interested shareholder and (6) any other transaction which is similar in purpose
or effect to the foregoing.

     Keystone's special shareholder vote requirements do not apply to any
transaction approved by a majority of the "disinterested directors."  A
disinterested director is any member of the Keystone Board who is not an
interested shareholder or an affiliate, associate or representative of an
interested shareholder and who (1) was a director before the interested
shareholder became an interested shareholder or (2) is a successor to a
disinterested director and was recommended for election by a majority of the
disinterested directors then on the Board.

                                      -64-
<PAGE>
 
     FFWM's Certificate requires that certain "business combinations" with or
upon a proposal by an "interested stockholder" be approved by the votes of the
holders of 80% of the voting power of the voting stock of FFWM not beneficially
owned by the interested stockholder.  An "interested stockholder" is defined by
FFWM's Certificate to mean any person who is either (1) the beneficial owner of
10% or more of the voting power of FFWM's voting stock, (2) an affiliate of FFWM
who was the beneficial owner of 10% or more of such voting power at any time in
the previous two years or (3) a transferee which in the previous two years
received voting stock from an interested stockholder in a transaction not
involving a public offering.

     The "business combinations" subject to FFWM's special vote requirements
include (1) a merger, consolidation or share exchange of FFWM or a subsidiary
with an interested stockholder, (2) the sale, lease, exchange, pledge, transfer
or other disposition by FFWM or a subsidiary to an interested stockholder of
assets having a fair market value equal to 25% or more of FFWM's consolidated
assets, (3) the issuance or transfer by FFWM or a subsidiary to an interested
stockholder of securities of FFWM or a subsidiary for consideration equal to 25%
or more of the fair market value of the outstanding FFWM Common Stock, (4) any
reclassification of securities, recapitalization, merger, consolidation or other
transaction, whether or not involving an interested stockholder, which has the
direct or indirect effect of increasing the percentage of any class of FFWM's
equity or convertible securities which is directly or indirectly owned by an
interested stockholder and (5) the adoption of any plan for the liquidation or
dissolution of FFWM or a subsidiary proposed by or on behalf of an interested
stockholder.

     FFWM's special shareholder vote requirements do not apply to any business
combination approved by a majority of the "disinterested directors."  A
disinterested director is any member of the FFWM Board who (1) has no material
financial interest in the interested stockholder, (2) is not a director of the
interested stockholder, (3) is not affiliated with the interested stockholder
and (4) was not elected or appointed as a director of FFWM through the voting
power or influence of the interested stockholder within two years preceding the
date that approval of the business combination by the disinterested directors is
required.  FFWM's special shareholder vote requirements also do not apply to any
business combination in which consideration is received by the shareholders of
FFWM and which satisfies certain specified price and procedural conditions.

     FFWM 10% Vote Limitation.  Under FFWM's Certificate, any shares of FFWM
Common Stock beneficially owned by a person in excess of 10% of the outstanding
shares are not entitled to voting rights.  The 10% limitation does not apply if
the offer to acquire, or beneficial ownership of, shares in excess of the limit
has been approved by a two-thirds vote of FFWM's Board of Directors, excluding
any directors who are not disinterested directors.


Board of Directors

     Classified Boards. Both Keystone's Articles and FFWM's Certificate divide
the Board of Directors into three classes, each consisting of one-third (or as
near as may be) of the whole number of the Board of Directors. One class of
directors is elected at each Annual Meeting of Shareholders, and each class
serves for a term of three years.

     The number of directors which constitute Keystone's full Board of Directors
may be increased or decreased only by the Board of Directors, by a vote
including a majority of the disinterested directors then in office, and except
as otherwise required by law, vacancies on Keystone's Board of Directors,
including vacancies resulting from an increase in the size of the Board, may be
filled only by the Board of Directors by a similar vote.  Keystone Directors
elected by the Board to fill vacancies serve for the full remainder of the term
of the class to which they have been elected.

     The number of directors which constitute FFWM's full Board of Directors
also may be increased or decreased only by the Board of Directors.  In the
absence of an interested stockholder, the vote required is a majority of the
entire Board.  During any time in which the Board is considering whether or has
determined that there is an interested stockholder, the vote required is two-
thirds of the entire Board.  Any increase or decrease in

                                      -65-
<PAGE>
 
the number of directors must be apportioned among the three classes by a two-
thirds vote of the directors, determined after giving effect to the increase or
decrease. Vacancies on FFWM's Board of Directors, including vacancies resulting
from an increase in the size of the Board, may be filled only by the Board of
Directors by the vote of a majority of the directors in office. FFWM Directors
elected by the Board to fill vacancies serve for the full remainder of the term
of the class to which they have been elected.

     Removal of Directors.  Keystone's Articles provide that a director, any
class of directors or the entire Board of Directors may be removed from office
by shareholder vote only for cause and only if, in addition to any other vote
required by law, such removal is approved by a majority of the voting power of
the outstanding voting stock of Keystone which is not beneficially owned by an
interested shareholder.

     FFWM's Certificate provides that a director may be removed from office only
for cause by the vote of at least 80% of the voting power of FFWM's outstanding
voting stock at a meeting called expressly for that purpose with at least 30
days prior written notice to the director or directors to be removed.

     Nomination of Director Candidates.  Keystone's Articles and FFWM's Bylaws
require that any shareholder intending to nominate a candidate for election as a
director must give the corporation advance written notice of the nomination,
containing certain specified information.  Keystone's Articles require that the
notice must be given not later than 120 days in advance of the meeting at which
the election is to be held.  FFWM's Bylaws require the notice to be given at
least 30 days in advance of the meeting at which the election is to be held,
except that if less than 40 days' notice or public disclosure of the meeting
date is given by FFWM, the notice may be given within 10 days after the date
notice of the meeting date was mailed or publicly disclosed.


Shareholder Meetings

     FFWM's Certificate provides that special meetings of shareholders may be
called only by the Chairman of the Board, the President or by a two-thirds vote
of FFWM's Board of Directors.  Although under the BCL Keystone shareholders do
not have a statutory right to call a special meeting of shareholders, Keystone's
Bylaws currently provide that special meeting may be called by the shareholders
by a written request of the holders of at least 20% of the outstanding shares of
Keystone Common Stock.  FFWM's Certificate also provides that any action by the
shareholders of FFWM must be taken at a duly called annual or special meeting
and may not be taken by written consent.  Although the shareholders of Keystone
may take action by written consent without a shareholder meeting, under the BCL
any such action would require the unanimous written consent of all Keystone
shareholders.

     FFWM's Bylaws require that in order for any proposal by an FFWM shareholder
to be considered at an annual meeting, the shareholder must provide FFWM with
written notice of the proposal, containing specified information, not less than
30 days prior to the date of the annual meeting.  Keystone's Articles and Bylaws
do not contain any special provisions requiring advance notice of shareholder
proposals intended to be presented at a Keystone annual meeting.  However, in
order to be considered for inclusion in Keystone's or FFWM's proxy statement for
an annual meeting, a shareholder proposal must be submitted in compliance with
SEC regulations requiring, among other things, that the proposal be received by
the corporation 120 days prior to the date of the proxy statement for the
preceding annual meeting.


Amendment of Charter and Bylaws

     Keystone's Articles require the votes of the holders of (1) 75% of the
voting power of all outstanding voting stock of Keystone and (2) a majority of
the voting power of the voting stock not beneficially owned by an interested
shareholder to approve any amendment to Keystone's Articles or Bylaws.  The
special voting requirement does not apply to any amendment approved by a
majority of the disinterested directors if at the time of such approval the
disinterested directors constitute a majority of Keystone's Board.  Except as to
matters for which

                                      -66-
<PAGE>
 
a shareholder vote is required by statute, Keystone's Board may also amend the
Bylaws without shareholder approval by a vote including a majority of the
disinterested directors then in office.

     FFWM's Certificate provides that the affirmative vote of the holders of at
least 80% of the voting power of the outstanding FFWM voting stock is required
to amend certain provisions of FFWM's Certificate or any provision of FFWM's
Bylaws. The Certificate provisions subject to this special voting requirement
include the special vote provisions described under "Voting Rights--Special
Votes for Certain Transactions" above, the provisions described under "Voting
Rights--FFWM 10% Vote Limitation" above, the provisions relating to FFWM's Board
of Directors and absence of cumulative voting described under "Voting Rights--
General" and "Board of Directors" above, the provisions restricting the call of
special meetings and action by written consent described under "Shareholder
Meetings" above, the provisions relating to director liability and
indemnification described above under "FFWM Plan of Merger--Interests of Certain
Persons in the Transaction, and the provisions requiring an 80% vote for
amendments. Under the GCL, the remaining provisions of FFWM's Certificate may be
amended with the affirmative vote of a majority of the outstanding shares of
FFWM Common Stock. However, no Certificate amendment may be adopted by
shareholders unless it is first proposed by FFWM's Board of Directors. Except as
to matters for which a shareholder vote is required by statute, FFWM's Board may
also amend the Bylaws without shareholder approval by a vote of two-thirds of
the directors then in office.


Keystone Shareholder Rights Plan

     Keystone has established a shareholder rights plan under which each share
of Keystone Common Stock presently outstanding or which is issued hereafter
prior to the Distribution Date (defined below) is granted one preferred share
purchase right (a "Right").  Each Right entitles the registered holder to
purchase from Keystone 5.333 one-thousandths (0.005333) of a share of Series A
Junior Participating Preferred Stock, par value $1.00 per share (the "Preferred
Shares"), of Keystone at a price of $56.00 per 5.333 one-thousandths of a
Preferred Share, subject to adjustment in the event of stock dividends and
similar events occurring prior to the Distribution Date.  Each 5.333 one-
thousandths of a Preferred Share would have voting, dividend and liquidation
rights which are the approximate equivalent of one share of Keystone Common
Stock.

     The Rights are not exercisable until the Distribution Date, which is the
earlier to occur of (I) 10 days following a public announcement that a person or
group (an "Acquiring Person") has acquired beneficial ownership of 20% or more
of the outstanding Keystone Common Stock or (ii) 10 business days (unless
extended by the Board of Directors prior to any person or group becoming an
Acquiring Person) following the commencement of, or announcement of an intention
to make, a tender offer or exchange offer the consummation of which would result
in the beneficial ownership by a person or group of 20% or more of the
outstanding Keystone Common Stock.

     Until the Distribution Date, the Rights will be transferred with and only
with Keystone Common Stock, and the surrender for transfer of any certificate
for Keystone Common Stock will also constitute the transfer of the Rights
associated with the shares represented by such certificate.  As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights will be mailed to holders of record of Keystone Common Stock as of
the close of business on the Distribution Date, and the Rights will then become
separately tradable.

     In the event that any person becomes an Acquiring Person, each holder of a
Right, other than Rights beneficially owned by the Acquiring Person or its
associates or affiliates (which will be void), will thereafter have the right to
receive upon exercise that number of Common Shares or, at the option of
Keystone, Preferred Shares (or shares of a class or series of Keystone's
preferred stock having equivalent rights, preferences and privileges) or, in
certain circumstances, other securities or assets, having a market value of two
times the exercise price of the Right.  In the event that after the first public
announcement that any person has become an Acquiring Person, Keystone is
acquired in a merger or other business combination transaction or 50% or more of
its consolidated assets or earning power are sold, proper provision will be made
so that each holder of a Right, other than rights beneficially owned by the
Acquiring Person or its associates or affiliates (which will be void) will
thereafter have

                                      -67-
<PAGE>
 
the right to receive, upon exercise of the Right, that number of shares of
common stock of the acquiring company which at the time of such transaction will
have a market value of two times the exercise price of the Right.

     At any time after the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding Keystone Common Stock and prior to
the acquisition by such person or group of 50% or more of the outstanding
Keystone Common Stock, the Board of Directors may exchange the Rights (other
than Rights owned by such person or group, which have become void), in whole or
in part, at an exchange ratio of one share of Keystone Common Stock, or 5.333
one-thousandths of a Preferred Share (or of a share of a class or series of
Keystone's preferred stock having equivalent rights, preferences and
privileges), or, in certain circumstances, an amount of other securities or
assets having equivalent value, per Right (subject to adjustment).

     At any time prior to the acquisition by a person or group of beneficial
ownership of 20% or more of the outstanding Keystone Common Stock, the Board of
Directors may redeem the Rights in whole, but not in part, at a price of $.01
per Right.

     The terms of the Rights may be amended by the Board of Directors without
the consent of the holders of the Rights before the Distribution Date in any
respect whatever, except for an amendment that would reduce the redemption
price.  Prior to any person becoming an Acquiring Person, Keystone may without
the consent of the holders of the Rights lower the 20% thresholds referred to
above to not less than the greater of (I) any percentage greater than the
largest percentage of the outstanding Keystone Common Stock then known to
Keystone to be beneficially owned by any person or group of affiliated or
associated persons and (ii) 10%.  The Rights will expire on February 8, 2000,
unless the expiration date is extended or unless the Rights are earlier redeemed
by Keystone as described above.


Pennsylvania Business Corporation Law

     The provisions of Keystone's Articles and Bylaws described under "Voting
Rights" and "Board of Directors" above and Keystone's shareholder rights plan
are in addition to certain provisions of Chapter 25 of the BCL which may have
the effect of discouraging or rendering more difficult a hostile takeover
attempt against Keystone.

     Under Section 2538 of the BCL, any merger, consolidation, share exchange or
sale of assets between Keystone or a subsidiary and any shareholder of Keystone,
any division of Keystone in which any shareholder receives a disproportionate
amount of any shares or other securities of any corporation resulting from the
division, any voluntary dissolution of Keystone in which a shareholder is
treated differently from other shareholders of the same class or any
reclassification in which any Keystone shareholder's voting or economic interest
in the corporation is materially increased relative to substantially all other
shareholders must, in addition to any other shareholder vote required, be
approved by a majority of the votes which all shareholders other than the
shareholder receiving the special treatment are entitled to cast with respect to
the transaction.  This special vote requirement does not apply to a transaction
(1) which has been approved by a majority vote of the Board, without counting
the vote of certain directors affiliated with or nominated by the interested
shareholder or (2) in which the consideration to be received by the shareholders
is not less than the highest amount paid by the interested shareholder in
acquiring shares of the same class.

     Under Subchapter 25E of the BCL, if any person or group acting in concert
acquires voting power over Keystone shares representing 20% or more of the votes
which all shareholders of Keystone would be entitled to cast in an election of
directors, any other shareholder may demand that such person or group purchase
such shareholder's shares at a price determined in an appraisal proceeding.

     Under Subchapter 25G of the BCL, Keystone may not engage in merger,
consolidation, share exchange, division, asset sale or a variety of other
"business combination" transactions with a person which becomes the "beneficial
owner" of shares representing 20% or more of the voting power in an election of
directors of Keystone unless (1) the business combination or the acquisition of
the 20% interest is approved by the Board of Directors of

                                      -68-
<PAGE>
 
Keystone prior to the date the 20% interest is acquired, (2) the person
beneficially owns at least 80% of the outstanding shares and the business
combination (a) is approved by a majority vote of the disinterested shareholders
and (b) satisfies certain minimum price and other conditions prescribed in
Subchapter 25F, (3) the business combination is approved by a majority vote of
the disinterested shareholders at a meeting called no earlier than five years
after the date the 20% interest is acquired or (4) the business combination (a)
is approved by shareholder vote at a meeting called no earlier than five years
after the date the 20% interest is acquired and (b) satisfies certain minimum
price and other conditions prescribed in Subchapter 25F.

     Keystone has elected to opt out from coverage by Subchapter 25G of the BCL,
which would have required a shareholder vote to accord voting rights to control
shares acquired by a 20% shareholder in a control-share acquisition, and
Subchapter 25H of the BCL, which would have required a person or group to
disgorge to Keystone any profits received from a sale of Keystone's equity
securities within 18 months after the person or group acquired or offered to
acquire 20% of Keystone's voting power or publicly disclosed an intention to
acquire control of Keystone.


Delaware General Corporation Law

     The provisions of FFWM's Certificate described above under "Voting Rights--
Special Votes for Certain Transactions" are in addition to restrictions on
business combinations between FFWM and a substantial shareholder imposed by
Section 203 of the GCL. Under Section 203, FFWM may not engage in a "business
combination" with an "interested stockholder" for a period of three years
following the time that the shareholder became an interested stockholder unless
(1) prior to such time FFWM's Board of Directors approved either the business
combination or the transaction which resulted in the shareholder becoming an
interested stockholder, (2) upon consummation of the transaction in which the
shareholder became an interested stockholder, the interested stockholder owned
at least 85% of the outstanding FFWM Common Stock, excluding shares owned by
persons who are both directors and officers of FFWM or by certain employee stock
plans or (3) at or subsequent to such time the business combination is approved
by FFWM's Board of Directors and authorized at an annual or special meeting by
the vote of at least two-thirds of the FFWM Common Stock which is not
beneficially owned by the interested stockholder. For purposes of Section 203,
an "interested stockholder" is generally (1) a beneficial owner of 15% or more
of the outstanding FFWM Common Stock or (2) an affiliate or associate of FFWM
which was a 15% beneficial owner at any time during the preceding three years.
The definition of "business combination" under Section 203 includes transactions
similar to those covered by the special voting provision of FFWM's Certificate
described above under "Voting Rights--Special Votes for Certain Transactions."


Dissenters' Rights

     The BCL provides for dissenters' rights in a variety of transactions
including:  (I) mergers or consolidations to which a corporation is a party
(other than mergers not requiring a shareholder vote); (ii) certain sales,
leases or exchanges of all or substantially all of the assets of a corporation;
and (iii) certain share exchanges or plans of division.  However, except in the
case of (1) a merger, consolidation, share exchange or division in which their
shares would be converted into or exchanged for something other than shares of
the surviving, new, acquiring or other corporation (or cash in lieu of
fractional shares) or (2) a transaction in which certain shareholders receive
materially different treatment from that accorded other holders of the same
class or series of shares, shareholders of a Pennsylvania business corporation
are not entitled to dissenters' rights in any of the transactions mentioned
above if their stock is either listed on a national securities exchange or held
of record by 2,000 or more shareholders.  Although Keystone Common Stock is not
listed on a national securities exchange, it is held of record may more than
2,000 shareholders.

     The GCL also provides for dissenters' rights in certain mergers or
consolidations involving FFWM.  However, except in the case of a merger or
consolidation in which they would be required to accept for their shares
something other than (1) stock of the surviving or resulting corporation or (2)
stock of another corporation which is listed on a national securities exchange,
designated as a NASDAQ National Market System security or held of

                                      -69-
<PAGE>
 
record by more than 2,000 shareholders (or cash in lieu of fractional shares),
the shareholders of a Delaware corporation are not entitled to dissenters'
rights under the GCL if their stock is either listed on a national securities
exchange, designated as a NASDAQ National Market System security or held of
record by more than 2,000 shareholders. Although FFWM Common Stock is a NASDAQ
National Market System security, because under the FFWM Plan of Merger the Stock
Election may not be available to all FFWM shareholders desiring to make that
election, shareholders of FFWM will have the right to dissent from the FFWM
Merger. See "FFWM Plan of Merger--Dissenters' Rights of FFWM Shareholders."


Preferred Stock

     Both Keystone's Articles and FFWM's Certificate authorize the corporation
to issue shares of preferred stock. Keystone's Articles authorize up to
8,000,000 shares of Keystone preferred stock, and FFWM's Certificate authorizes
up to 2,000,000 shares of FFWM preferred stock.

     The authorized shares of preferred stock are issuable in one or more series
on the terms set by the resolution or resolutions of the Board of Directors of
Keystone or FFWM providing for the issuance thereof.  Each series of preferred
stock would have such dividend rate, which might or might not be cumulative,
such voting rights, which might be general or special, and such liquidation
preferences, redemption and sinking funds provisions, conversion rights or other
rights and preferences, if any, as the Board of Directors may determine.  Except
for such rights as may be granted to the holders of any series of preferred
stock in the resolution establishing such series or as required by law, all of
the voting and other rights of the shareholders of Keystone and FFWM belong
exclusively to the holders of common stock.


Dividend Rights

     The holders of FFWM Common Stock and Keystone Common Stock are entitled to
dividends when, as and if declared by their Board of Directors out of funds
legally available therefor.  However, if Keystone or FFWM preferred stock is
issued, the Board of Directors of the corporation may grant preferential
dividend rights to the holders of such stock which would prohibit payment of
dividends on the corporation's common stock unless and until specified dividends
on the preferred stock had been paid.


Liquidation Rights

     Upon liquidation, dissolution or winding up of Keystone or FFWM, whether
voluntary or involuntary, the holders of Keystone or FFWM Common Stock are
entitled to share ratably in the assets of the corporation available for
distribution after all liabilities of the corporation have been satisfied.
However, if preferred stock is issued by Keystone or FFWM, the Board of
Directors of the corporation may grant preferential liquidation rights to the
holders of such stock which would entitle them to be paid out of the assets of
the corporation available for distribution before any distribution is made to
the holders of common stock.


Miscellaneous

     There are no preemptive rights, sinking fund provisions, conversion rights,
or redemption provisions applicable to Keystone or FFWM Common Stock.  Holders
of fully paid shares of Keystone or FFWM Common Stock are not subject to any
liability for further calls or assessments.

                                                              February ___, 1997

Board of Directors
Keystone Financial, Inc.

Front & Market Street
P.O. Box  3660
Harrisburg, Pennsylvania  17105-3660

Dear Members of the Board:

     Set forth herein is Danielson Associates Inc.'s ("Danielson Associates")
independent opinion as to the "fairness" of the offer by Keystone Financial,
Inc. ("Keystone") to buy all of the outstanding common stock of Financial Trust
Corp ("Financial Trust") through an exchange of stock having a value at the time
of the offer of about $375 million.

     In the course of preparing the opinion, the markets served by Financial
Trust have been analyzed; its business and prospects have been discussed with
management; its financial performance has been compared with banks in the
region; the sale prices of comparable banks have been analyzed; and any unique
characteristics have been considered.  We also reviewed the Agreement and Plan
of Reorganization and the Agreement and Plan of Merger (collectively, "Plan of
Merger") between Keystone and Financial Trust.

     This opinion is based on data supplied by Keystone and Financial Trust, and
it relies on some public information, all of which is believed to be reliable,
but neither the completeness nor accuracy of such information can be guaranteed.
The opinion assumes, based on Financial Trust's managements representation, that
there are no significant loan problems beyond what are stated in recent reports
to regulatory agencies and in the monthly report to the directors.  We also have
reviewed the financial projections made by Keystone, including estimates of cost
savings and revenue enhancements expected to result from the merger and have
assumed that they have been reasonably prepared and reflect the best currently
available estimates and judgments of Keystone.

     In determining the "fairness" of the offer, we also have compared the
common stock to be exchanged by Keystone with other similar bank holding
companies. In so doing, we also compared Keystone's financial performance with
these comparable financial institutions.

     Based on the foregoing, we are of the opinion on the date hereof that the
offer made by Keystone to acquire all of the common stock of Financial Trust
pursuant to the Plan of Merger is fair from a financial point of view to
Keystone and its shareholders.

                                 Respectfully submitted,



                                 Arnold G. Danielson
                                 Chairman
                                 Danielson Associates Inc.

(DATE)

Board of Directors
Financial Trust Corp.
1415 Ritner Highway
Carlisle, PA  17013

Directors:

     You have requested our opinion as to the fairness, from a financial point
of view, to the shareholders of Financial Trust Corp ("Financial Trust") of the
financial terms of the proposed merger between Financial Trust and Keystone
Financial, Inc. ("Keystone Financial"). The terms of the proposed merger (the
"Proposed Merger") between Financial Trust and Keystone Financial are set forth
in the Agreement and Plan of Reorganization dated as of December 19, 1996, (the
"Agreement") and provide that each outstanding share of Financial Trust Common
Stock, par value $5.00 per share, will receive 1.65 shares of Common Stock, par
value $2.00 per share, of Keystone Financial determined in conformity with the
exchange ratio set forth in the Agreement, with cash to be paid in lieu of any
fractional shares.

     Berwind Financial Group, L.P., as part of its investment banking business,
regularly is engaged in the valuation of assets, securities and companies in
connection with various types of assets and securities transactions, including
mergers, acquisitions, private placements and valuation for various other
purposes, and in the determination of adequate consideration in such
transactions.

     In arriving at our opinion, we have, among other things:  (i) reviewed the
historical financial performances, current financial positions and general
prospects of Financial Trust and Keystone Financial, (ii) reviewed the
Agreement, (iii) reviewed and analyzed the stock market performance of Financial
Trust and Keystone Financial, (iv) studied and analyzed the consolidated
financial and operating data of Financial Trust and Keystone Financial, (v)
considered the terms and conditions of the Proposed Merger between Financial
Trust and Keystone Financial as compared with the terms and conditions of
comparable bank and bank holding company mergers and acquisitions, (vi) met
and/or communicated with certain members of Financial Trust's and Keystone
Financial's senior management to discuss their respective operations, historical
financial statements and future prospects, (vii) reviewed the Joint Proxy
Statement/Prospectus, and (viii) conducted such other financial analyses,
studies and investigations as we deemed appropriate.

     Our opinion is given in reliance on information and representations made or
given by Financial Trust and Keystone Financial, and their respective officers,
directors, auditors, counsel and other agents, and on filings, releases and
other information issued by Financial Trust and Keystone Financial including
financial statements, financial projections, and stock price data as well as
certain information from recognized independent sources.  We have not
independently verified the information concerning Financial Trust and Keystone
Financial nor other data which we have considered in our review and, for
purposes of the opinion set forth below, we have assumed and relied upon the
accuracy and completeness of all such information and data.  Additionally, we
assume that the Proposed Merger is, in all respects, lawful under applicable
law.

     With regard to financial and other information relating to the general
prospects of Financial Trust and Keystone Financial, we have assumed that such
information has been reasonably prepared and reflects the best currently
available estimates and judgments of the managements of Financial Trust and
Keystone Financial as to Financial Trust's and Keystone Financial's most likely
future performance.  In rendering our opinion, we have assumed that in the
course of obtaining the necessary regulatory approvals for the Proposed Merger
no conditions will be imposed that will have a material adverse effect on the
contemplated benefits of the Proposed Merger to Financial Trust.  Berwind also
assumed that there would not occur any change in applicable law or regulation
that would cause a material adverse change in the prospects or operations of
Keystone Financial after the Proposed Merger.

     Our opinion is based upon information provided to us by the managements of
Financial Trust and Keystone Financial, as well as market, economic, financial
and other conditions as they exist and can be evaluated only as of the date
hereof and speaks to no other period.  Our opinion pertains only to the
financial consideration of the Proposed Merger and does not constitute a
recommendation to the Board of Financial Trust and does not constitute a
recommendation to Financial Trusts shareholders as to how such shareholders
should vote on the Proposed Merger.

     Based on the foregoing, it is our opinion that, as of the date hereof, the
Proposed Merger between Financial Trust and Keystone Financial is fair, from a
financial point of view, to the shareholders of Financial Trust.

                                 Sincerely,



                                 BERWIND FINANCIAL GROUP, L.P.

                [Letterhead of Alex. Brown & Sons Incorporated]



                                                               November 26, 1996


First Financial Corporation of Western Maryland
118 Baltimore Street
Cumberland, MD  21502

Dear Members of the Board of Directors:

     First Financial Corporation of Western Maryland ("First Financial" or the
"Company") and Keystone Financial, Inc. ("Keystone"), a Pennsylvania
Corporation, have entered into an Agreement and Plan of Merger dated as of
November 26, 1996 (the "Agreement"). Pursuant to the Agreement, First Financial
shall be merged with and into Keystone (the "Merger"), and each share of First
Financial common stock issued and outstanding immediately prior to the effective
time of the Merger will be converted into the right to receive, at the election
of the holder thereof, either (i) 1.29 shares (the "Exchange Ratio") of common
stock of Keystone or (ii) an amount in cash equal to the Exchange Ratio
multiplied by Keystone's average closing bid price for the 20 consecutive
trading day preceding the closing date. The total consideration ("Total
Consideration") shall mean the sum of the stock election described under (i),
which will equal approximately 60% of the Total Consideration, and the cash
election described under (ii), which will equal approximately 40% of the Total
Consideration. You have requested our opinion as to whether the Total
Consideration is fair, from a financial point of view, to First Financial's
stockholders.

its investment banking business, is engaged in the valuation of businesses
and their securities in connection with mergers and acquisitions, negotiated
underwritings, private placements and valuations for estate, corporate and other
purposes.  We have acted as financial advisor to the Board of Directors of First
Financial in connection with the transaction described above and will receive a
fee for our services, the entirety of which is contingent upon consummation of
the Merger. Alex. Brown regularly publishes research reports regarding the
banking industry and the businesses and securities of publicly traded companies
in the banking industry.  In the ordinary course of business, Alex. Brown may
actively trade the securities of banks and thrifts for our own account and the
account of our customers and, accordingly, may at any time hold a long or short
position in such securities.

     In connection with this opinion, we have reviewed certain publicly
available financial information and other information concerning First Financial
and Keystone and certain internal analyses and other information furnished to us
by First Financial and Keystone.  We have also held discussions with the members
of the senior managements of First Financial and Keystone regarding the business
prospects of their respective companies and the joint prospects of a combined
company.  In addition, we have (i) reviewed the reported prices and trading
activity for the common stock of both First Financial and Keystone, (ii)
compared certain financial and stock market information for First Financial and
Keystone with similar information for certain companies whose securities are
publicly traded, (iii) reviewed the financial terms of certain recent business
combinations which we deemed comparable in whole or in part, (iv) reviewed the
terms of the Agreement, and (v) performed such other studies and analyses and
considered such other factors as we deemed appropriate.

     We have not independently verified the information described above and for
purposes of this opinion have assumed the accuracy, completeness and fairness
thereof.  With respect to the information relating to the prospects of First
Financial and Keystone, we have assumed that such information reflects the best
currently available

judgments and estimates of the managements of First Financial and Keystone as to
the likely future financial performances of their respective companies. In
addition, we have not made nor been provided with an independent valuation or
appraisal of the assets and liabilities of First Financial and Keystone, nor
have we been furnished with any such evaluations or appraisals. We are not
expressing our opinion as to the value of Keystone's common stock when issued
pursuant to the Merger or the prices at which Keystone's common stock will trade
subsequent to such issuance. Our opinion is based on market, economic and other
conditions as they exist and can be evaluated as of the date of this letter.

     Our advisory services and the opinion expressed herein were prepared for
the use of the Board of Directors of First Financial and do not constitute a
recommendation to any stockholder as to how such stockholder should vote.  We
hereby consent to the inclusion of this opinion in its entirety as an exhibit to
any proxy or registration statement distributed in connection with the Merger.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date of this letter, the Total Consideration is fair, from a financial point of
view, to First Financials stockholders.

                                    Very truly yours,

                              OF FFWM SHAREHOLDERS


                        DELAWARE GENERAL CORPORATION LAW
                         SECTION 262--APPRAISAL RIGHTS

     262 APPRAISAL RIGHTS.--(a) Any stockholder of a corporation of this State
who holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to (S)228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of his shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b)  Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to (S)251 (other than a merger effected pursuant to subsection
(g) of Section 251), 252, 254, 257, 258, 263 or 264 of this title:

          (1)  Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the holders of the surviving corporation as
     provided in subsection (f) of (S)251 of this title.

          (2)  Notwithstanding paragraph (1) of this subsection, appraisal
     rights under this section shall be available for the shares of any class or
     series of stock of a constituent corporation if the holders thereof are
     required by the terms of an agreement of merger or consolidation pursuant
     to (S)(S)251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

               a. Shares of stock of the corporation surviving or resulting from
          such merger or consolidation, or depository receipts in respect
          thereof;

               b. Shares of stock of any other corporation, or depository
          receipts in respect thereof, which shares of stock or depository
          receipts at the effective date of the merger or consolidation will be
          either listed on a national securities exchange or designated as a
          national market system security on an interdealer quotation system by
          the National Association of Securities Dealers, Inc. or held of record
          by more than 2,000 holders;

                                      A-6
<PAGE>
 
               c.  Cash in lieu of fractional shares or fractional depository
          receipts described in the foregoing subparagraphs a. and b. of this
          paragraph; or

               d. Any combination of the shares of stock, depository receipts
          and cash in lieu of fractional shares or fractional depository
          receipts described in the foregoing subparagraphs a., b. and c. of
          this paragraph.

          (3)  In the event all of the stock of a subsidiary Delaware
     corporation party to a merger effected under (S)253 of this title is not
     owned by the parent corporation immediately prior to the merger, appraisal
     rights shall be available for the shares of the subsidiary Delaware
     corporation.

     (c)  Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d)  Appraisal rights shall be perfected as follows:

          (1)  If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section.  Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares.
     Such demand will be sufficient if it reasonably informs the corporation of
     the identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares.  A proxy or vote against the merger or
     consolidation shall not constitute such a demand.  A stockholder electing
     to take such action must do so by a separate written demand as herein
     provided.  Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or

          (2)  If the merger or consolidation was approved pursuant to (S)228 or
     (S)253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights.  Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation.  Any stockholder
     entitled to appraisal rights may, within twenty days after the date of
     mailing of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares.  Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intend thereby to demand the appraisal
     of such holders shares.  If such notice did not notify stockholders of the
     effective date of the merger or consolidation, either (i) each such
     constituent corporation shall send a second notice before the effective
     date of the merger or consolidation notifying each of the holders of any
     class or series of stock of such constituent corporation that are entitled
     to appraisal rights of the effective date of the merger or consolidation or
     (ii) the surviving or resulting

                                      A-7
<PAGE>
 
     corporation shall send such a second notice to all such holders on or
     within 10 days after such effective date; provided, however, that if such
     second notice is sent more than 20 days following the sending of the first
     notice, such second notice need only be sent to each stockholder who is
     entitled to appraisal rights and who has demanded appraisal of such
     holder's shares in accordance with this subsection. An affidavit of the
     secretary or assistant secretary or of the transfer agent of the
     corporation that is required to give either notice that such notice has
     been given shall, in the absence of fraud, be prima facie evidence of the
     facts stated therein. For purposes of determining the stockholders entitled
     to receive either notice, each constituent corporation may fix, in advance,
     a record date that shall be not more than 10 days prior to the date the
     notice is given; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, the record date shall be
     such effective date. If no record date is fixed and the notice is given
     prior to the effective date, the record date shall be the close of business
     on the day next preceding the day on which the notice is given.

     (e)  Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation.  Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

     (f)  Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation.  If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list.  The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated.  Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable.  The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be approved by the
Court, and the costs thereof shall be borne by the surviving or resulting
corporation.

     (g)  At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights.  The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h)  After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value.  In determining such fair value, the
Court shall take into account all relevant factors.  In determining the fair
rate of interest, the Court may consider all relevant factors, including the
rate of interest which the surviving or resulting corporation would have had to
pay to borrow money during the pendency of the proceeding.  Upon application by
the surviving or resulting corporation or by any stockholder entitled to
participate

                                      A-8
<PAGE>
 
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.

     (i)  The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto.  Interest may be simple or compound, as the Court
may direct.  Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by the certificates upon the surrender to the corporation of the
certificates representing such stock.  The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or any state.

     (j)  The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances.  Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k)  From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l)  The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized
and unissued shares of the surviving or resulting corporation.  (Last amended
by Ch. 349, L. `96, eff. 7-1-96.)

Item 20.   Indemnification of Directors and Officers.

          1.  Pennsylvania Business Corporation Law.  Sections 1741 and 1742 of
the Pennsylvania Business Corporation Law (the "BCL") provide that a business
corporation shall have the power to indemnify any person who was or is a party,
or is threatened to be made a party, to any proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that such person is or
was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such proceeding, if such
person acted in good faith and in a manner he reasonably believed to be in, or
not opposed to, the best interests of the corporation, and, with respect to any
criminal proceeding, had no reasonable cause to believe his conduct was
unlawful.  In the case of an action by or in the right of the corporation, such
indemnification is limited to expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement
of such action, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person has been adjudged to be liable to
the corporation unless, and only to the extent that, a court determines upon
application that, despite the adjudication of liability but in view of all the
circumstances, such person is fairly and reasonably entitled to indemnity for
the expenses that the court deems proper.

          BCL Section 1744 provides that, unless ordered by a court, any
indemnification referred to above shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification is
proper in the circumstances because the indemnitee has met the applicable
standard of conduct.  Such determination shall be made:

           (1)  by the Board of Directors by a majority vote of a quorum
     consisting of directors who were not parties to the proceeding; or

           (2)  if such a quorum is not obtainable, or if obtainable and a
     majority vote of a quorum of disinterested directors so directs, by
     independent legal counsel in a written opinion; or

           (3)  by the shareholders.

     Notwithstanding the above, BCL Section 1743 provides that to the extent
that a director, officer, employee or agent of a business corporation is
successful on the merits or otherwise in defense of any proceeding referred to
above, or in defense of any claim, issue or matter therein, such person shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection therewith.

     BCL Section 1745 provides that expenses (including attorneys' fees)
incurred by an officer, director, employee or agent of a business corporation in
defending any proceeding may be paid by the corporation in advance of the final
disposition of the proceeding upon receipt of an undertaking to repay the amount
advanced if it is ultimately determined that the indemnitee is not entitled to
be indemnified by the corporation.

     BCL Section 1746 provides that the indemnification and advancement of
expenses provided by, or granted pursuant to, the foregoing provisions is not
exclusive of any other rights to which a person seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders or directors or
otherwise, and that indemnification may be granted under any bylaw, agreement,
vote of shareholders or disinterested directors or otherwise for any action
taken or any failure to take any action whether or not the corporation would
have the power to indemnify the person under any other provision of law and
whether or not the indemnified liability arises or arose from any action by or
in the right of the corporation, provided, however, that no indemnification may
be

                                     II-1
<PAGE>
 
made in any case where the act or failure to act giving rise to the claim for
indemnification is determined by a court to have constituted willful misconduct
or recklessness.

     BCL Section 1747 permits a Pennsylvania business corporation to purchase
and maintain insurance on behalf of any person who is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or other enterprise, against any liability asserted against such
person and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify the
person against such liability under the provisions described above.

     2.  Indemnification By-Law.  Section 8.01 of the registrant's By-Laws (the
"Indemnification By-Law") was adopted by the shareholders at their Annual
Meeting held on May 28, 1987 and became effective on that date.  Under the
Indemnification By-Law, except as prohibited by law, every director and officer
of the registrant is entitled as of right to be indemnified by the registrant
against all expenses and liabilities incurred in connection with any actual or
threatened claim or proceeding, whether civil, criminal, administrative,
investigative or other, whether brought by or in the right of the registrant or
otherwise, in which the director or officer may be involved in any manner, by
reason of his being or having been a director or officer of the registrant or by
reason of the fact that he is or was serving at the request of the registrant as
a director, officer, employee, fiduciary or other representative of another
corporation or other entity.  In an action brought by a director or officer
against the registrant, the director or officer is only entitled to
indemnification for expenses in certain circumstances.  Each director and
officer is also entitled as of right to have his expenses in defending an action
paid in advance by the registrant prior to final disposition of the action,
subject to any obligation which may be imposed to reimburse the registrant in
certain events.  The Indemnification By-Law establishes a procedure whereby a
director or officer may bring an action against the registrant if a written
claim for indemnification or advancement of expenses is not paid by the
registrant in full within thirty days after the claim has been presented.  The
director or officer is also entitled to advancement of expenses in this
proceeding.  The only defense to an action to recover a claim for
indemnification is that the indemnitee's conduct was such that under
Pennsylvania law the registrant is prohibited from indemnifying the indemnitee.
The only defense to an action to recover payment of expenses in advance is
failure by the indemnitee to make an undertaking to reimburse the registrant if
such an undertaking is required.

     The Indemnification By-Law applies to every action, other than actions
filed prior to January 27, 1987, except that it does not apply to the extent
that Pennsylvania law does not permit its application to any breach or failure
of performance of duty by a director or officer occurring prior to January 27,
1987.  Any amendment or repeal of the Indemnification By-Law will operate
prospectively only and will not affect any action taken, or failure to act, by a
director or officer prior to the adoption of such amendment or repeal.

     3.  Director and Officer Liability Insurance.  The registrant maintains
director and officer liability insurance covering its directors and officers
with respect to liability which they may incur in connection with their serving
as such, which liability could include liability under the Securities Act of
1933.  Under the insurance, the registrant is entitled to reimbursement for
amounts as to which the directors and officers are indemnified under the
Indemnification By-Law.  The insurance may also provide certain additional
coverage for the directors and officers against certain liability even though
such liability is not subject to indemnification under the Indemnification By-
Law.

     4.  Indemnification Agreements.  At their Annual Meeting held on May 28,
1987, the shareholders also approved a proposed form of Indemnification
Agreement to be entered into between the registrant and each of its present and
future directors and such other officers, employees and agents of the registrant
and its subsidiaries as shall be designated from time to time by the Board of
Directors.

     The form of agreement provides essentially the same rights to
indemnification against liabilities and expenses as are provided in the
Indemnification By-Law.  In addition, the form of agreement requires the
registrant to either maintain the liability insurance coverage currently in
effect for the benefit of the contractee or to hold the contractee harmless to
the full extent of such coverage.

                                     II-2

     Further, the form of agreement provides that if the full indemnification
claimed by the contractee may not be paid by the registrant because prohibited
by law and the registrant is jointly liable with the contractee as to the matter
for which indemnification was sought (or would be so liable if the registrant
were joined in such matter), the contractee has a right to contribution from the
registrant for the amount of any expenses and liabilities incurred by the
contractee as to such matter based on the relative benefits received by the
registrant and the contractee from the transaction from which the liability
arose and the relative fault of the registrant (including the registrant's other
directors, officers, employees or agents) and the contractee in connection with
the events which resulted in such expenses or liability, as well as any other
relevant equitable considerations.

     Under the form of agreement, a contractee is entitled to the rights to
indemnification for expenses and liability, advancement of expenses and
contribution provided by the agreement notwithstanding any amendment or repeal
of the Indemnification By-Law.  In addition, although a change in law
restricting indemnification rights would automatically restrict the
indemnification rights provided under the Indemnification By-Law, the form of
agreement provides that a change in law restricting indemnification rights will
not affect the rights of a contractee under the agreement unless the law so
requires.

Item 22.  Undertakings.

     The undersigned registrant hereby undertakes as follows:

          (1) that, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
     of 1934 that is incorporated by reference in the registration statement
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

          (2) to deliver or cause to be delivered with the prospectus, to each
     person to whom the prospectus is sent or given, the latest annual report to
     security holders that is incorporated by reference in the prospectus and
     furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule
     14c-3 under the Securities Exchange Act of 1934; and, where interim
     financial information required to be presented by Article 3 of Regulation
     S-X is not set forth in the prospectus, to deliver, or cause to be
     delivered to each person to whom the prospectus is sent or given, the
     latest quarterly report that is specifically incorporated by reference in
     the prospectus to provide such interim financial information.

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

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

          (5) that insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the provisions described
     under Item 20 above, or otherwise, the registrant has been advised that in
     the opinion of the Securities and Exchange Commission such indemnification
     is against public policy as expressed in the Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the registrant of expenses incurred
     or paid by a director, officer or controlling person of the registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, the registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the Act and
     will be governed by the final adjudication of such issue.

          (6) to respond to requests for information that is incorporated by
     reference into the Joint Proxy Statement/Prospectus pursuant to Items 4,
     10(b), 11 or 13 of Form S-4, within one business day of receipt of such
     request, and to send the incorporated documents by first class mail or
     other equally prompt means. This includes information contained in
     documents filed subsequent to the effective date of the registration
     statement through the date of responding to the request.

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

                                     II-4

to or bound by any option, call, warrant, conversion privilege or other
agreement obligating FTC at present, at any future time or upon the occurrence
of any event to issue or sell any shares of FTC Common Stock or other capital
stock of FTC. None of the terms of any Outstanding FTC Options provide that upon
consummation of the Merger (i) unexercised options shall be converted into
options for greater than the number of shares of Keystone Common Stock the
optionee would have received in the Merger had the option been exercised prior

the number of shares of Keystone Common Stock subject to the option.

         ------------
outstanding shares of capital stock of Financial Trust Company, Chambersburg

Bank (collectively, the "FTC Bank Subsidiaries") and of Financial Trust Services
Company, Financial Trust Life Insurance Company and FT Realty Co. (all of the

no other direct or indirect subsidiaries. All of the issued and outstanding
capital stock of the FTC Subsidiaries is duly and validly authorized and issued,
fully paid and nonassessable (except with respect to the national banks as
provided in Section 55 of the National Bank Act) and is owned by FTC or an FTC
Subsidiary free and clear of any liens, security interests, encumbrances,
restrictions or other rights of any third person with respect thereto. There are
no options, calls, warrants, conversion privileges or other agreements
obligating any FTC Subsidiary at present or upon the occurrence of any event to
issue or sell any shares of its capital stock. Each of Financial Trust Company
and Chambersburg Trust Company is a bank and trust company duly organized,
validly existing and in good standing under the laws of the Commonwealth of
Pennsylvania; each of First National Bank and Trust Co. and Washington County

and in good standing under the laws of the United States; Financial Trust
Services Company is a trust company duly organized, validly existing and in good
standing under the laws of the Commonwealth of Pennsylvania; Financial Trust
Life Insurance Company is a corporation duly organized, validly existing and in

which are legally required) to own its assets and to transact the business in
which it is presently engaged.

    3.4. Joint Ventures, etc. Neither FTC nor any FTC Subsidiary is a party to
         -------------------
any joint venture, a general or limited partner of any partnership or the owner
of any equity or similar interest in any other person (including without
limitation any interest pursuant to which FTC or an FTC Subsidiary has or may in
any circumstance have an obligation to make a capital contribution to, or be
liable for or on account of the liabilities, acts or omissions of, such other
person) except (i) FTC's ownership of all the issued and outstanding capital
stock of the FTC Subsidiaries identified in Section 3.3 and (ii) the ownership
of marketable equity securities held as investments in the ordinary course of
business and not exceeding 5% of the outstanding shares of any class and (iii)
joint venture or other interests disclosed to Keystone in writing on the date
hereof (the "FTC Joint Ventures").

approval of its shareholders and regulatory authorities, to perform its
obligations under the Merger Agreement. This Agreement, the Merger Agreement and
the Warrant Agreement have been duly and validly executed and delivered by FTC,

affecting creditors' rights or by the application by a court of equitable
principles. Neither the execution and delivery by FTC of this Agreement, the
Merger Agreement or the Warrant Agreement, compliance by FTC with any provision

shareholders and regulatory authorities, compliance by FTC with any provision of
the Merger Agreement will (i) violate any provision of the Articles of

Warrant Agreement would require the approval of regulatory authorities).

a consistent basis (except as indicated therein) and fairly present the
consolidated financial condition, assets and liabilities of FTC at the dates
thereof and the consolidated results of operations, shareholders' equity and
cash flows of FTC for the periods stated therein, subject, in the case of the
interim financial statements, to normal and recurring year-end audit adjustments
and except that the interim financial statements do not contain all of the notes

    3.7. Absence of Certain Changes. Since December 31, 1995 there has not been
         --------------------------

condition, results of operations, adequacy of the allowance for loan losses or
business of FTC and the FTC Subsidiaries taken as a whole. Since December 31,

the nine months ended September 30, 1995 remain open. All taxes, deficiencies,
interest and penalties which are reflected as due under such returns or which

returns are accurate in all material respects, and to the best of FTC's
knowledge there is no material proposed deficiency, assessment, penalty or
delinquency with respect to any of such returns or any of the taxes reflected as
due and payable thereby. All taxes, deficiencies, interest and penalties which
are reflected as due under such returns or which have been assessed as a result
of audits thereof have either been paid in full or have been accrued or

         ----------
to all of their properties and assets (including those reflected in the
consolidated balance sheet of FTC at December 31, 1995, except such as have been
disposed of in the ordinary course of business) free of any mortgage,
encumbrance, lien or security interest, except pledges of assets to secure
public deposits and minor imperfections in title and encumbrances which do not
materially detract from the value or impair the use of the properties affected
thereby. All leases material to FTC pursuant to which FTC or any FTC Subsidiary,
as lessee, leases real or personal property are valid and effective in
accordance with their respective terms, and there is not, under any of such
leases, any material existing default by FTC or any FTC Subsidiary or any event
which with notice or lapse of time or both would constitute such a material
default.

    3.10. Employee Contracts and Plans. Except as disclosed to Keystone in

subject to (i) any contract of employment or consulting agreement not terminable
at will without penalty, (ii) any collective bargaining agreement or (iii) any
profit sharing, pension, retirement, thrift, savings, incentive compensation,
deferred compensation, bonus, stock option, stock purchase, restricted stock,
stock appreciation right, performance share, performance unit, severance, salary
continuation, holiday, vacation, disability, insurance, medical or other
employee benefit, incentive or welfare plan, policy, contract or arrangement
("Employee Benefit Plan"). FTC has heretofore made available to Keystone copies
of all Employee Benefit Plans of FTC and the FTC Subsidiaries, including
individual employment contracts and stock option agreements. There are no
pending or threatened strikes or labor stoppages involving any employees of FTC
or any FTC Subsidiary, nor is FTC or any FTC Subsidiary aware of any organizing
activity seeking to certify a collective bargaining unit or representative for
any of such employees. All retirement and employee benefit or welfare plans of
FTC or any FTC Subsidiary have been maintained and operated in accordance with
their terms, and all such plans which are subject to the Employee Retirement
Income Security Act of 1974 ("ERISA") and/or the Code have been maintained and
operated in material compliance with all applicable provisions of ERISA and the
Code and the regulations thereunder and are not subject to any accumulated
funding deficiency within the meaning of ERISA and the regulations thereunder or
to any outstanding liability to the Pension Benefit Guaranty Corporation. No
"prohibited transaction" has occurred and is continuing with respect to any such
plan, nor has any "reportable event" occurred in respect thereof, as such terms
are defined in ERISA and the regulations thereunder, and no such plan is a
"Multiemployer Plan" or a "Multiple Employer Plan", as such terms are defined in
ERISA and the regulations thereunder. The current value of the assets of each
FTC Employee Benefit Plan that is subject to Title IV of ERISA exceeds the
present value of the accrued benefits under such plan based upon the actuarial
assumptions (to the extent reasonable) presently used by such plan, and there is
no complete or partial withdrawal liability within the meaning of Sections 4205
and 4203 of ERISA (and there would be no such liability assuming a complete or
partial withdrawal from all FTC Employee Benefit Plans at the Effective Time)
with respect to any such plan. There are no pending, threatened or anticipated
claims (other than routine claims for benefits) by, on behalf of or against any
of the FTC Employee Benefit Plans or any trusts related thereto.

    3.11. Other Material Contracts. Neither FTC nor any FTC Subsidiary is a

party or subject to any other contract or agreement which, if entered into after
the date hereof, would require the consent of Keystone under Section 5.1 hereof.

    3.12. Litigation and Other Proceedings. Neither FTC nor any FTC Subsidiary
          --------------------------------
is a party or subject to any pending, or to the knowledge of FTC may become a
party or subject to any threatened, action, suit, arbitration, administrative
proceeding or investigation, or judicial or administrative order, judgment or
decree, which individually or in the aggregate will have, or could reasonably be
expected to

                                      -8-
<PAGE>
 
have, a material adverse effect on the consolidated financial condition, results
of operations or business of FTC and the FTC Subsidiaries taken as a whole.

    3.13. Compliance with Laws; Regulatory Matters. FTC and the FTC Subsidiaries
          ---------------------------------------- 
are in compliance in all material respects with all laws, rules and regulations,
all orders, directives and supervisory letters of, and all agreements, memoranda
of understanding or similar arrangements with, regulatory authorities and all
other legal requirements applicable to them or their businesses. Neither FTC nor
any FTC Subsidiary is subject to any order, directive or supervisory letter of,
or agreement, memorandum of understanding or similar arrangement (including
board resolutions adopted at the request of a regulatory authority) with, any
regulatory authority restricting its operations, restricting it from taking any
action or requiring that certain actions be taken, and FTC has no knowledge that
any such order, directive, supervisory letter, agreement, memorandum of
understanding or similar arrangement is threatened, contemplated or under
consideration by any regulatory authority.

    3.14. Environmental Matters. To the knowledge of FTC, (a) no Hazardous
          --------------------- 
Substances (as hereinafter defined) have been stored, treated, dumped, spilled,
disposed of, discharged, released or deposited in violation of any law or
regulation or in a manner which would subject FTC or any FTC Subsidiary to
liability under any law or regulation at, under or on (1) any property now
owned, occupied or leased ("Present Property") by FTC, any FTC Subsidiary, any
former subsidiary of FTC or any FTC Joint Venture (each, an "FTC Entity"), (2)
any property previously owned, occupied or leased ("Former Property") by any FTC
Entity during the time of such previous ownership, occupancy or lease; or (3)
any Participation Facility (as hereinafter defined) during the time that any FTC
Entity participated in the management of, or may be deemed to be or to have been
an owner or operator of, such Participation Facility; (b) no FTC Entity has
disposed of, or arranged for the disposal of, Hazardous Substances in violation
of any law or regulation or in a manner which would subject FTC or any FTC
Subsidiary to liability under any law or regulation from any Present Property,
Former Property or Participation Facility, and no owner or operator of a
Participation Facility disposed of, or arranged for the disposal of, Hazardous
Substances in violation of any law or regulation or in a manner which would
subject FTC or any FTC Subsidiary to liability under any law or regulation from
a Participation Facility during the time that any FTC Entity participated in the
management of, or may be deemed to be or to have been an owner or operator of,
such Participation Facility; and (c) no Hazardous Substances have been stored,
treated, dumped, spilled, disposed of, discharged, released or deposited in
violation of any law or regulation or in a manner which would subject FTC or any
FTC Subsidiary to liability under any law or regulation at, under or on any Loan
Property (as hereinafter defined), nor is there, with respect to any such Loan
Property, any violation of environmental law which could materially adversely
affect the value of such Loan Property to an extent which could prevent or delay

                             -----------------
foregoing, FTC may afford such access, enter into any such discussions,
negotiations or agreements or understandings, or authorize or permit any of its
directors, officers, employees or agents to do so if the Board of Directors of
FTC, after consulting with counsel, determines that such actions should be taken
or permitted in the exercise of its fiduciary duties. If FTC becomes aware of
any offer or proposed offer to acquire any such shares of capital stock of
itself or any FTC Subsidiary or any significant portion of its or any FTC
Subsidiary's assets (regardless of the form of the proposed transaction) or of
any other matter which could adversely affect this Agreement or the Merger, FTC
shall immediately give notice thereof to Keystone.

                                      -17-

    6.9. Transactions Involving Keystone. Keystone shall not enter into any
         -------------------------------
agreement for a merger, consolidation or share exchange with or into any other
person, unless the surviving or resulting corporation, if other than Keystone,
shall have agreed in writing to be bound by the terms of this Agreement, the
Merger Agreement and the Warrant Agreement. In the event that under the terms of
any such agreement the outstanding Keystone Common Stock is converted into or
exchanged for other securities of any person, cash or other property, the terms
of this Agreement and the Merger Agreement shall be appropriately amended so
that the shareholders of FTC shall receive in the Merger, for each share of FTC
Common Stock, the consideration per share received by the holders of Keystone
Common Stock in such transaction multiplied by the Exchange Ratio (as defined in
the Merger Agreement and appropriately adjusted to reflect such event), provided
that fractional shares or fractional units of other securities or property may
be paid in cash based on the value of $26.50 for one whole share of Keystone
Common Stock. It is understood that the condition contained in Section 2.1(d)
shall not prevent Keystone from entering into any such transaction, but FTC
shall not be required to amend or waive such condition. Keystone shall obtain
the consent of FTC, which consent shall not unreasonably be withheld, before
entering into an agreement for any such transaction which would result in the
acquisition by Keystone of a business for which (excluding the impact of the
Merger and Keystone's proposed merger with First Financial Corporation of
Western Maryland) Keystone would be required under Rule 3-05(b)(2) of SEC
Regulation S-X to include separate financial statements in a registration
statement of Keystone under the Securities Act.

    6.10. Access and Information. Pending the Effective Time, FTC and Keystone
          ----------------------
will each afford the other party and its authorized representatives reasonable
access during normal business hours to its properties, books and records and
personnel and those of its subsidiaries and will furnish promptly to the other
party such financial and operating data and other information relating to its
and its subsidiaries' business, assets and personnel as the other party may
reasonably request.

taken at a meeting duly convened for that purpose, provided that the party
electing to terminate shall have performed its obligations under Section 6.3
hereof; or

         (d) by either party at any time after a final judicial or regulatory
determination (as to which all periods for appeal have expired an no appeal
shall be pending) denying any regulatory approval required for the Merger or
imposing conditions or requirements which Keystone in its reasonable judgment
has determined to be materially adverse to its interests; or

         (e) by either party at any time after December 31, 1997 in the event of
failure to satisfy any of the conditions to the obligations of the party

absolute discretion and without necessity of specifying any reason therefor,
elect to terminate this Agreement, without liability of either party, by written
notice to FTC. Keystone's right to terminate pursuant to this Section 7.4 shall

provided in Section 8.6 not later than 5:00 p.m., Eastern Standard Time, on
January 8, 1997.

    7.5. FTC Due Diligence. Following the execution and delivery of this

unless written notice of exercise is received by Keystone at its address
provided in Section 8.6 not later than 5:00 p.m., Eastern Standard Time, on

<PAGE>
 
the Merger, to the extent permitted by law, Keystone (with respect to

Time.

    (b) Keystone agrees that following the Merger, any amendment to the
provisions of the charter or by-laws of any FTC Subsidiary referred to in
Section 8.12(a) which would have the effect of reducing or hindering the rights
of indemnity or limitation of liability currently afforded under such provisions
to the current or former directors or officers of any FTC Subsidiary shall
operate prospectively only and shall not apply to events, acts or omissions
occurring prior to the adoption thereof.

    (c) In the event that Keystone or an FTC Subsidiary or its successors or
assigns (i) consolidates with or merges into another person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii) transfers all or substantially all of its properties or assets to any
person, then, and in each such case, proper provisions shall be made so that the
successor or transferee in such transaction shall assume the obligations of

effect of such transaction is that the successor or transferee assumes such
obligations by operation of law.

          ---------------------
charter of at least one of FTC's bank subsidiaries shall survive the Merger.

    8.14. Keystone Benefit Plans. As soon as administratively practicable
          ----------------------
following the Merger, Keystone shall take appropriate action so that employees
of the FTC Subsidiaries and employees of FTC who become employees of Keystone
shall be entitled to participate in generally applicable Keystone employee
benefit plans on the same basis as other similarly situated employees of
Keystone and its subsidiaries. Prior service of such employees with FTC or an
FTC Subsidiary shall be counted in

                                      -23-
<PAGE>
 
determining eligibility to participate in such plans and for purposes of vesting
of benefits, but shall not be counted for purposes of benefit accrual.

    IN WITNESS WHEREOF, the parties hereto, by their officers thereunto duly
authorized, have executed this Agreement as of the day and year first above
written.

                          AGREEMENT AND PLAN OF MERGER
                          ----------------------------


    THIS AGREEMENT dated as of December 19, 1996 between KEYSTONE FINANCIAL,
INC., a Pennsylvania corporation ("Keystone"), and FINANCIAL TRUST CORP, a
Pennsylvania corporation ("FTC"),

                              W I T N E S S E T H:
                              ------------------- 

    WHEREAS, Keystone and FTC have entered into an Agreement and Plan of
Reorganization of even date herewith (the "Reorganization Agreement") which
provides, among other things, for the merger of FTC and Keystone (the "Merger");

    NOW, THEREFORE, in consideration of their mutual covenants and agreements
contained herein and in the Reorganization Agreement, and for the purpose of
stating the method, terms and conditions of the Merger, including the rights of
the shareholders of FTC, and such other details and provisions as are deemed
desirable, the parties hereto, intending to be legally bound hereby, agree as
follows:

    1. The Merger. Subject to the terms and conditions of this Agreement and the
       ---------- 
Reorganization Agreement, and in accordance with the laws of the Commonwealth of
Pennsylvania, at the Effective Time (as defined in Section 8.1 of the
Reorganization Agreement) FTC shall be merged with and into Keystone, which
shall be the surviving corporation.

    2. Articles of Incorporation and By-Laws. The Articles of Incorporation and
       -------------------------------------
By-Laws of Keystone as in effect immediately prior to the Effective Time shall
be the Articles of Incorporation of the surviving corporation.

    3. Board of Directors. Upon the merger becoming effective, the Board of
       ------------------
Directors of the surviving corporation shall consist of:

         (a) the persons who where directors of Keystone immediately prior to
the Merger, without change in their respective terms of office by reason of the
Merger;

         (b) Ray L. Wolfe, the Chairman and Chief Executive Officer of FTC, to
serve, subject to the By-Laws of Keystone and any other applicable
qualifications, for a term expiring at the Annual Meeting of Shareholders of
Keystone in 2000; and

         (c) two additional persons to be designated by FTC, subject to the
approval of Keystone, to serve, subject to the By-Laws of Keystone and any other
applicable qualifications, for terms expiring at the Annual Meetings of
Shareholders of Keystone in 1998 and 1999.

    If prior to the Effective Time Ray L. Wolfe or either of such persons
designated by FTC becomes unable to serve or declines to serve as a director of
Keystone, FTC shall be entitled to designate a substitute director acceptable to
Keystone. If Ray L. Wolfe shall be available and willing to serve as a director
of Keystone following the Merger as hereinabove provided, then upon the Merger
becoming effective he shall, without

                                      A-1
<PAGE>
 
necessity of further action, be deemed to have been elected as Chairman of the
Board of Directors of Keystone, to serve in such capacity in accordance with the
By-Laws of Keystone.

    4. Conversion of FTC Shares. (a) Subject to the provisions of Section 5
       ------------------------
hereof with respect to the payment of fractional shares in cash, upon the Merger
becoming effective, each share of Common Stock, par value $5.00 per share, of
FTC ("FTC Common Stock") shall, by virtue of the Merger and without any action
on the part of the holder thereof, be converted into and become a right to
receive 1.65 shares (the "Exchange Ratio") of Common Stock, par value $2.00 per
share, of Keystone ("Keystone Common Stock"). No change will be made by reason
of the Merger in the shares of Keystone Common Stock outstanding immediately
prior to the Effective Time.
    
    (b) If after the date of this Agreement and prior to the Effective Time the
number of outstanding shares of Keystone Common Stock or FTC Common Stock shall
have been increased or decreased by reason of a dividend payable in shares of
Common Stock or a split or combination of outstanding shares, or if pursuant to
Section 24 of the Keystone Rights Agreement (as defined in the Reorganization
Agreement) all Rights (as defined in the Keystone Rights Agreement) then
outstanding (other than Rights which have become void pursuant to Section 7(f)
of the Keystone Rights Agreement) shall have been exchanged for shares of
Keystone Common Stock, then the Exchange Ratio shall be adjusted (a) in the case
of any such event involving the Keystone Common Stock by multiplying the
Exchange Ratio by a fraction the numerator of which shall be the number of
shares of Keystone Common Stock issued and outstanding immediately after such
event and the denominator of which shall be the number of shares of Keystone
Common Stock issued and outstanding immediately prior to such event and (b) in
the case of any such event involving the FTC Common Stock by multiplying the
Exchange Ratio by a fraction the numerator of which shall be the number of
shares of FTC Common Stock issued and outstanding immediately prior to such
event and the denominator of which shall be the number of shares of FTC Common
Stock issued and outstanding immediately after such event. The Exchange Ratio
shall also be appropriately adjusted to reflect any capital reorganization
involving the reclassification of the Keystone Common Stock or the FTC Common
Stock subsequent to the date of this Agreement and prior to the Effective Time.
Similar adjustments shall be made to the amount payable in lieu of fractional
shares.

    5. Surrender and Exchange of FTC Certificates. As promptly as practicable
       ------------------------------------------ 
after the Effective Time, Keystone shall cause to be sent to each person who
immediately prior to the Effective Time was a holder of record of FTC Common
Stock transmittal materials and instructions for surrendering certificates for
FTC Common Stock ("Old Certificates") in exchange for a certificate or
certificates for the number of whole shares of Keystone Common Stock to which
such person is entitled under Section 4 hereof.

    No certificates for fractional shares of Keystone Common Stock shall be
issued in connection with the Merger. In lieu thereof, Keystone shall issue to
any holder of FTC Common Stock certificates otherwise entitled to a fractional
share, upon surrender of such certificates in accordance with the instructions
furnished by Keystone, a check for an amount of cash equal to the fraction of a
share of Keystone Common Stock represented by the certificates so surrendered
multiplied by the value of $26.50 for one whole share of Keystone Common Stock.

    If any dividend on Keystone Common Stock is declared after the Effective
Time, the declaration shall include dividends on all whole shares of Keystone
Common Stock into which shares of FTC Common Stock have been converted under
this Agreement, but no former holder of record of FTC Common Stock shall be
entitled to receive payment of any such dividend until surrender of the
shareholder's Old Certificates shall have been effected in accordance with the
instructions furnished by Keystone. Upon surrender for exchange of a
shareholder's Old Certificates, such shareholder shall be entitled to receive

                                      A-2
<PAGE>
 
from Keystone an amount equal to all such dividends (without interest thereon
and less the amount of taxes, if any, which may have been imposed or paid
thereon) declared, and for which the payment date has occurred, on the whole
shares of Keystone Common Stock into which the shares represented by such Old
Certificates have been converted.

    After the Effective Time, there shall be no transfer on the stock transfer
books of FTC or Keystone of shares of FTC Common Stock. If Old Certificates are
presented for transfer after the Effective Time, they shall be canceled and
certificates representing whole shares of Keystone Common Stock (and a check in
lieu of any fractional share) shall be issued in exchange therefor as provided
herein.

    6. Failure to Surrender Old Certificates. In the event that any Old
       -------------------------------------
Certificates have not been surrendered for exchange in accordance with Section 5
hereof on or before the second anniversary of the Effective Time, Keystone may
at any time thereafter, with or without notice to the holders of record of such
Old Certificates, sell for the accounts of any or all of such holders pursuant
to Section 1532 of the Pennsylvania Business Corporation Law any or all of the
shares of Keystone Common Stock which such holders are entitled to receive under
Section 4 hereof (the "Unclaimed Shares"). Any such sale may be made by public
or private sale or sale at any broker's board or on any securities exchange in
such manner and at such times as Keystone shall determine. If in the opinion of
counsel for Keystone it is necessary or desirable, any Unclaimed Shares may be
registered for sale under the Securities Act of 1933 and applicable state laws.
Keystone shall not be obligated to make any sale of Unclaimed Shares if it shall
determine not to do so, even if notice of sale of the Unclaimed Shares has been
given. The net proceeds of any such sale of Unclaimed Shares shall be held for
the holders of the unsurrendered Old Certificates whose Unclaimed Shares have
been sold, to be paid to them upon surrender of their Old Certificates. From and
after any such sale, the sole right of the holders of the unsurrendered Old
Certificates whose Unclaimed Shares have been sold shall be the right to collect
the net sale proceeds held by Keystone for their respective accounts, and such
holders shall not be entitled to receive any interest on such net sale proceeds
held by Keystone.

    7. Termination and Amendment. Notwithstanding prior approval by the
       -------------------------
shareholders of FTC, this Agreement shall be terminated and the Merger shall be
abandoned in the event that prior to the Effective Time the Reorganization
Agreement is terminated as provided therein. If there is such termination after
the delivery of Articles of Merger to the Pennsylvania Department of State, the
parties shall execute and file prior to the Effective Time with such Department
a statement of termination pursuant to Section 1902 of the Pennsylvania Business
Corporation Law. Notwithstanding prior approval by the shareholders of FTC or
Keystone, this Agreement may be amended in any respect in the manner and subject
only to the limitations set forth in Section 7.1 of the Reorganization
Agreement.

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

will constitute an original. The headings and captions contained herein are for

<PAGE>

serves as such at any time while this Article is in effect, and each such
director shall be deemed to be so serving in reliance on the provisions of this
Article. Any amendment or repeal of this Article or adoption of any By-Law or
other provision of the Articles of the Corporation which has the effect of
increasing director liability shall operate prospectively only and shall not
affect any action taken, or any failure to act, prior to the adoption of such
amendment, repeal, By-Law or other provision.

    8.  Board Of Directors.

    8.1.  Number, Election, Etc.  The business and affairs of the
Corporation shall be managed by or under the direction of a Board of Directors
comprised as follows:

         (a)  Number.  The Board of Directors shall consist of such number of
     persons as may from time to time be fixed by the Board pursuant to a
     resolution adopted by a majority vote of the Disinterested Directors then
     in office, plus such number of additional directors as the holders of any
     class or series of stock having a preference over the Common Stock as to
     dividends or assets, voting separately as a class or series, shall have the
     right from time to time to elect.

         (b)  Classes, Election and Terms.  The directors elected by the
     holders of Voting Stock shall be classified in respect of the time for
     which they shall severally hold office by dividing them into three classes,
     as nearly equal in number as possible.  If such classes of directors are
     not equal, the Board of Directors, by a majority vote of the Disinterested
     Directors then in office, shall determine which class shall contain an
     unequal number of directors.  At each annual meeting of shareholders, the
     shareholders shall elect directors of the class whose term then expires, to
     hold office until the third succeeding annual meeting.  Each director shall
     hold office for the term for which elected and until his or her successor
     shall be elected and shall qualify.

         (c)  Removal of Directors.  Any director, any class of directors or
     the entire Board of Directors may be removed from office by shareholder
     vote at any time, without assigning any cause, but only if shareholders
     entitled to cast at least 75% of the votes which all shareholders would be
     entitled to cast at an annual election of directors or of such class of
     directors shall vote in favor of such removal; provided, however, that the
     shareholders shall have such power of removal without cause only if and so
     long as the general corporate law of the Corporation's state of
     incorporation specifically mandates such power.  If such power of removal
     without cause is not mandated by statute, the shareholders may remove a
     director or directors from office at any time only for cause and only if,
     in addition to any vote required by any other provision of law, these
     Articles or the By-Laws of the Corporation, such removal is approved by the
     affirmative vote of at least a majority of the voting power of the
     outstanding shares of Voting Stock of the Corporation which are not
     beneficially owned by an Interested Shareholder.

         (d)  Vacancies.  Vacancies in the members of the Board of Directors
     elected by the holders of Voting Stock, including vacancies resulting from
     an increase in the number of directors, shall be filled only by a majority
     vote of the Disinterested Directors then in office, though less than a
     quorum, except as otherwise required by law.  All such directors elected to
     fill vacancies shall hold office for a term expiring at the annual meeting
     of shareholders at which the term of the class to which they have been
     elected expires.  No decrease in the number of directors constituting the
     Board of Directors shall shorten the term of any incumbent director.

                                      -3-
<PAGE>
 
         (e)  Nominations of Director Candidates.  Nominations for the election
     of directors may be made only by the Board of Directors or a committee
     appointed by the Board of Directors or by any holder of record of stock
     entitled to vote in the election of the directors to be elected; but a
     nomination may be made by a shareholder only if written notice of such
     nomination has been received by the Secretary of the Corporation not later
     than 120 days in advance of the meeting at which the election is to be
     held.  Each such notice shall set forth: (1) the name and address of the
     shareholder who intends to make the nomination and of the person or persons
     to be nominated; (2) a representation that the shareholder is a holder of
     record of stock of the Corporation entitled to vote at such meeting and
     intends to appear in person or by proxy at the meeting to nominate the
     person or persons specified in the notice; (3) a description of all
     arrangements or understandings  between the shareholder and each nominee
     and any other person or persons (naming such person or persons) pursuant to
     which the nomination or nominations are to be made by the shareholder; (4)
     such other information regarding each nominee proposed by such shareholder
     as would be required to be included in a proxy statement filed pursuant to
     the proxy rules of the Securities and Exchange Commission, had the nominee
     been nominated by the Board of Directors; and (5) the consent of each
     nominee to serve as a director of the Corporation if so elected.  Only
     candidates who have been nominated in accordance with this Section 8.1(e)
     shall be eligible for election by the shareholders as directors of the
     Corporation.

    8.2.  Exception For Preferred Stock.  Whenever the holders of any class or
series of stock having a preference over the Common Stock of the Corporation as
to dividends or assets shall have the right, voting separately as a class or
series, to elect one or more directors of the Corporation or to take any other
action, none of the provisions of Section 8.1 shall apply with respect to the
director or directors elected or the action taken by the holders of such class
or series.

    8.3.  Authority To Amend By-Laws.  The Board of Directors may adopt, amend
and repeal the By-Laws with respect to those matters which are not, by statute,
reserved exclusively to the shareholders, provided that such power may be
exercised only by a vote including a majority of the Disinterested Directors
then in office.  No By-Law may be adopted, amended or repealed by the
shareholders unless, in addition to any other affirmative vote required by law,
these Articles or otherwise, such action is approved by the affirmative votes of
(a) the holders of at least 75% of the voting power of all then outstanding
shares of Voting Stock, voting together as a single class, and (b) the holders
of at least a majority of the voting power of the then outstanding shares of
Voting Stock which are not beneficially owned by an Interested Shareholder,
voting together as a single class; provided, however, that the additional
affirmative votes required by this Section 8.3 shall not apply to any
shareholder adoption, amendment or repeal of any By-Law provision if (a) such
action is recommended and submitted to the shareholders for their consideration
by the affirmative vote of a majority of the Disinterested Directors and (b) at
the time of such recommendation the Disinterested Directors constitute at least
a majority of the full Board of Directors, excluding any directors elected by
the holders of any class or series of stock having a preference over the Common
Stock as to dividends or assets.

    9.  Vote Required For Certain Transactions.

    9.1.  Special Vote For Certain Transactions.  In addition to any
affirmative vote required by law, these Articles or otherwise, and except as
otherwise expressly provided in Section 9.2:

         (a)  any merger, consolidation or share exchange of the Corporation or
     any Subsidiary with (1) any Interested Shareholder or with (2) any other
     person (whether or not itself an Interested Shareholder) which is, or after
     such merger, consolidation or share exchange would be, an Affiliate

         (b)  any sale, lease, exchange, mortgage, pledge, transfer or other
     disposition or security arrangement, investment, loan, advance, guarantee,
     agreement to purchase, agreement to pay, extension of credit, joint venture
     participation or other arrangement (in one transaction or a series of
     transactions) to, with or for the benefit of any Interested Shareholder or
     any Affiliate or Associate of any Interested Shareholder involving any
     assets, securities or commitments of the Corporation or any Subsidiary
     having an aggregate Fair Market Value and/or involving aggregate
     commitments equal to 5% or more of Total Assets;

         (c)  the issuance or transfer by the Corporation or any Subsidiary to
     any Interested Shareholder or any Affiliate or Associate of any Interested
     Shareholder (in one transaction or a series of transactions) of any
     securities of the Corporation or any Subsidiary having an aggregate Fair
     Market Value equal to 5% or more of Total Assets;

         (d)  the adoption of any plan or proposal for the liquidation or
     dissolution of the Corporation proposed by or on behalf of any Interested
     Shareholder or any Affiliate or Associate of any Interested Shareholder;

         (e)  any reclassification of securities (including any reverse stock
     split), or recapitalization of the Corporation, or any merger or
     consolidation of the Corporation with any of its Subsidiaries or any other
     transaction (whether or not with or into or otherwise involving an
     Interested Shareholder) which has the effect, directly or indirectly, of
     increasing the proportionate share of the outstanding shares of any class
     of equity securities or securities convertible into equity securities of
     the Corporation or any Subsidiary which is directly or indirectly
     beneficially owned by any Interested Shareholder or any Affiliate or
     Associate of any Interested Shareholder; or

         (f)  any other transaction or series of transactions similar in
     purpose or effect to, or any agreement, contract or other arrangement
     providing for, any one or more of the transactions specified in the
     foregoing subparagraphs (a) through (e); shall require the affirmative
     votes of (i) the holders of at least 75% of the voting power of all then
     outstanding shares of Voting Stock, voting together as a single class, and
     (ii) the holders of at least a majority of the voting power of the then
     outstanding shares of Voting Stock which are not beneficially owned by such
     Interested Shareholder, voting together as a single class.  Such
     affirmative votes shall be required notwithstanding the fact that no vote
     may be required, or that a lesser percentage may be specified, by law or in
     any agreement with any national securities exchange or otherwise.

    9.2.  Exception To Special Vote Requirements.  The provisions of Section
9.1 shall not be applicable to any transaction, and such transaction shall
require only such affirmative vote (if any) as is required by law, any other
provision of these Articles, any agreement with any national securities exchange
or otherwise, if the transaction shall have been approved by a majority of the
Disinterested Directors.

    10.  Definitions; Interpretation; Amendments.

    10.1.  Definitions.  For The Purposes Of Articles 8, 9, 10 And 11 Of These

<PAGE>
 
         (a)  A "person" shall mean any individual, firm, corporation,
     partnership, joint venture, trust or other entity and shall include any
     group comprised of any person and any other person with whom such person or
     any Affiliate or Associate of such person has any agreement, arrangement or
     understanding, directly or indirectly, for the purpose of acquiring,
     holding, voting or disposing of Voting Stock.  As used herein, the pronouns
     "which", "that" and "it" in relation to persons that are individuals shall
     be construed to mean "who" or "whom", "he" or "she" and "him" or "her", as
     appropriate.

         (b)  "Interested Shareholder" at any particular time shall mean any
     person (other than the Corporation or a Subsidiary, or an employee benefit
     plan of the Corporation or a Subsidiary, or a trustee or fiduciary of any
     such plan when acting in such capacity) which:

              (1)  is at such time the beneficial owner, directly or
          indirectly, of more than 20% of the voting power of the outstanding
          Voting Stock;

              (2)  is at such time an Affiliate of the Corporation and at any

          voting power of the then outstanding Voting Stock; or

              (3)  is at such time an assignee of or has otherwise succeeded to

          or succession shall have occurred in the course of a transaction or
          series of transactions not involving a public offering within the
          meaning of the Securities Act of 1933.

With respect to any particular transaction, the term "Interested Shareholder"
means any Interested Shareholder involved in such transaction, any Affiliate or
Associate of such Interested Shareholder and any other member of a group acting
in concert with such Interested Shareholder.

         (c)  A person shall be a "beneficial owner" of any shares of Voting
     Stock:

              (1)  which such person or any of its Affiliates or Associates

          (A) the right to acquire (whether or not such right is exercisable
          immediately) pursuant to any agreement, arrangement or understanding
          or upon the exercise of conversion rights, exchange rights, warrants
          or options, revocation of a trust, or otherwise, or (B) the right to

          Associates has any agreement, arrangement or understanding for the

          Voting Stock.  For the purposes of determining whether a person is an
          Interested Shareholder pursuant to paragraph (b) of this Section 10.1,

          include shares deemed owned by an Interested Shareholder through

     price or, if none, the highest closing bid quotation with respect to a
     share of such stock

                                      -7-

Directors, by a majority vote, are authorized to interpret all the terms and
provisions of these Articles and to determine, on the basis of information known
to them after reasonable inquiry, any fact necessary to determine compliance
with any such term or provision including, without limitation (a) whether a
person is an Interested Shareholder, (b)  the number of shares of Voting Stock
beneficially owned by any person, (c) whether a person is an Affiliate or
Associate of another person, (d) whether any articles of incorporation provision
required by Section 9.1(a) complies with such Section and is valid and
enforceable and (e) whether the assets which are the subject of any transaction
referred to in Section 9.1(b) have, or the consideration to be received for the
issuance or transfer of securities by the Corporation or any Subsidiary in any
transaction referred to in Section 9.1(c) has, an aggregate Fair Market Value
equal to 5% or more of Total Assets.  Any such interpretation or determination
made in good faith shall be binding and conclusive for all purposes of these
Articles.

    10.3.  Amendment, Repeal, Etc.  In addition to any affirmative vote
required by law, these Articles or otherwise, any amendment, alteration, change
or repeal of any provision of these Articles, or the adoption of any new
provision thereof, shall require the affirmative votes of (a) the holders of at
least 75% of the voting power of all then outstanding shares of Voting Stock,
voting together as a single class, and (b) the holders of at least a majority of

provision if (a) it is recommended and submitted to the shareholders for their
consideration by the affirmative vote of a majority of the Disinterested
Directors and (b) at the time of such recommendation the Disinterested Directors
constitute at least a majority of the full Board of Directors, excluding any
directors elected by the holders of any class or series of stock having a
preference over the Common Stock as to dividends or assets.

    11.  Consideration Of Other Factors.  The Board of Directors of the
Corporation, when evaluating any proposal:

                                      -8-

     corporation or person; or

         (c)  to purchase or otherwise acquire all or a Substantial Part of the

shall, in connection with the exercise of its judgment in determining what is in
the best interests of the Corporation and its shareholders, give due
consideration to all relevant factors, including without limitation, the
economic effect, both immediate and long-term, upon the Corporation's
shareholders, including shareholders, if any, not to participate in the
transaction, the social and economic effects on the employees, suppliers and
customers of, and others dealing with, the Corporation or any of its
subsidiaries and on the communities in which the Corporation and its
subsidiaries operate or are located.  The definitions set forth in Section 10.1
of Article 10 of these Articles shall apply to this Article 11.

      Re:  Keystone Financial, Inc. Registration Statement on Form S-4 re
           Shares of Common Stock Issuable in Mergers with (1) Financial
           Trust Corp and (2) First Financial Corporation of Western Maryland
           ------------------------------------------------------------------

Gentlemen:

    We have acted as counsel to Keystone Financial, Inc. ("Keystone") in
connection with:

    1.  The Agreement and Plan of Reorganization and the related Agreement
and Plan of Merger, each dated as of December 19, 1996 (collectively, the "FTC
Plan of Merger"), between Keystone and Financial Trust Corp, a Pennsylvania
corporation ("FTC").  The FTC Plan of Merger provides for the merger of FTC with
and into Keystone (the "FTC Merger").  At the time the FTC Merger becomes
effective, each issued and outstanding share of common stock, par value $5.00
per share, of FTC ("FTC Common Stock") will be converted into the right to
receive 1.65 shares of common stock, par value $2.00 per share, of Keystone
("Keystone Common Stock").

    2. The Agreement and Plan of Merger dated as of November 26, 1996 (the "FFWM
Plan of Merger") between Keystone and First Financial Corporation of Western
Maryland, a Delaware corporation ("FFWM"). The FFWM Plan of Merger provides for
the merger of FFWM with and into Keystone (the "FFWM Merger"). At the time the
FFWM Merger becomes effective, each issued and outstanding share of common
stock, par value $1.00 per share, of FFWM ("FFWM Common Stock") (other than
shares as to which the holders exercise dissenters' rights) will be converted
into the right to receive either (1) 1.29 shares of Keystone Common Stock or (2)
cash in the amount provided in the FFWM Plan of Merger, as elected by the holder
thereof or as otherwise determined as provided in the FFWM Plan of Merger.

    We are also acting as counsel to Keystone in connection with the
Registration Statement on Form S-4 (the "Registration Statement") to be filed by
Keystone with the Securities and Exchange Commission for the purpose of
registering under the Securities Act of 1933, as amended, the shares of Keystone
Common Stock into which outstanding FTC and FFWM Common Stock may be converted
in the Mergers. This opinion is being furnished to you for the purpose of being
filed as an Exhibit to the Registration Statement.

    In connection with this opinion we have examined, among other things:

    (1) executed copies of the FTC Plan of Merger and of the FFWM Plan of
         Merger;

Reed Smith Shaw & McClay

Keystone Financial, Inc.                    -2-                 January 23, 1997

        (2) a copy certified to our satisfaction of the Restated Articles of
            Incorporation of Keystone as in effect on the date hereof;

        (3) copies certified to our satisfaction of resolutions adopted by the
            Board of Directors of Keystone on November 21 and December 16, 1996
            and on January 23, 1997, including resolutions approving the FTC and
            FFWM Plans of Merger; and

        (4) such other documents, corporate proceedings, statutes and decisions
            as we considered necessary to enable us to furnish this opinion.

        We have assumed for the purposes of this opinion that:

        (1) the FTC Plan of Merger has been duly and validly authorized,
            executed and delivered by FTC;

        (2) the FTC Merger will be consummated in accordance with the terms of
            the FTC Plan of Merger;

        (3) the FFWM Plan of Merger has been duly and validly authorized,
            executed and delivered by FFWM; and

        (4) the FFWM Merger will be consummated in accordance with the terms of
            the FFWM Plan of Merger.

        Based upon the foregoing, we are pleased to advise you that, in our
        opinion:

        (1) the shares of Keystone Common Stock into which the outstanding FTC
            Common Stock will be converted in the FTC Merger will, at the time
            such Merger becomes effective, be duly authorized, validly issued,
            fully paid and nonassessable shares of Keystone Common Stock; and

        (2) the shares of Keystone Common Stock into which outstanding FFWM
            Common Stock will be converted in the FFWM Merger will, at the time
            such Merger becomes effective, be duly authorized, validly issued,
            fully paid and nonassessable shares of Keystone Common Stock.

    We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Opinions" in the Joint Proxy Statement/Prospectus forming a part of the
Registration Statement.

                                    Yours truly,

Dear Shareholder:

    THIS AGREEMENT dated as of December 19, 1996 (the "Agreement") between
                                                       ---------
KEYSTONE FINANCIAL, INC. ("Keystone") and FINANCIAL TRUST CORP (the
                           --------

                              W I T N E S S E T H:
                              ------------------- 

    WHEREAS, Keystone and the Corporation have, simultaneously with executing
this Agreement, entered into an Agreement and Plan of Reorganization and an
Agreement and Plan of Merger dated as of the date hereof (collectively, the
"Plan"); and
 ----

     WHEREAS, as a condition to Keystone's entry into the Plan and in
consideration of such entry, the Corporation has agreed to issue to Keystone, on
the terms and conditions set forth herein, warrants entitling Keystone to
purchase up to an aggregate of 2,113,706 shares (the "Shares") of the
                                                      ------
Corporation's common stock, par value $5.00 per share (the "Common Stock");
                                                            ------------     

     NOW, THEREFORE, in consideration of the execution of the Plan and the
agreements herein contained, Keystone and the Corporation, each intending to be
legally bound, agree as follows:

     1. Concurrently with the execution of the Plan and this Agreement, the
Corporation shall issue to Keystone a warrant or warrants in the form of
Attachment A hereto (the "Warrant", which term as used herein shall include any
                          -------
warrants issued upon transfer or exchange of the original Warrant or pursuant to
Paragraph 8 of this Agreement) to purchase up to 2,113,706 Shares of the Common
Stock. Each Warrant shall be exercisable at a price per Share of $43.725,
subject to adjustment as therein provided (the "Exercise Price"). So long as the
                                                --------------
Warrant is outstanding and unexercised, the Corporation shall at all times
maintain and reserve, free from preemptive rights, such number of authorized but
unissued or treasury shares of Common Stock as may be necessary so that the
Warrant may be exercised without additional authorization of Common Stock after
giving effect to all other options, warrants, convertible securities and other
rights to acquire shares of Common Stock at the time outstanding. The
Corporation represents and warrants that it has duly authorized the issuance of
the Shares upon exercise of the Warrant and covenants that the Shares issued
upon exercise of the Warrant shall be duly authorized, validly issued and fully
paid and nonassessable and subject to no preemptive rights. The Warrant and the
Shares are hereinafter collectively referred to, from time to time, as the
"Securities".
 ----------
           
     So long as the Warrant is owned by Keystone, in no event shall Keystone
exercise the Warrant for a number of shares of Common Stock, which when added to
the number of shares of Common Stock owned or controlled by Keystone (otherwise
than in a fiduciary capacity) would result in Keystone owning or controlling
(otherwise than in a fiduciary capacity) more than 19.9% of the shares of Common
Stock issued and outstanding immediately after giving effect to such exercise.

     2. Subject to the terms and conditions hereof, Keystone may exercise or
sell the Warrant, in whole or in part, upon: (i) a willful breach of the Plan by
the Corporation which would permit termination of the Plan by Keystone; (ii) the
failure of the Corporation's shareholders to approve the Plan at a meeting
called for such purpose after the announcement by any person (other than
Keystone or any of its affiliates) of a bona fide offer or proposal to acquire
10% or more of the Common Stock, or to acquire, merge or consolidate with the
Corporation or any FTC Subsidiary, as such term is defined the Plan (hereinafter
called a "Corporation Subsidiary"), or to purchase or acquire all or
substantially all of the assets of the Corporation or any Corporation
Subsidiary; (iii) the acquisition by any person (other than Keystone or any of
its affiliates) after the date of this Agreement of beneficial ownership of 1%
or more of the outstanding
<PAGE>
 
Common Stock if following such acquisition such person would beneficially own
10% or more of the Common Stock, in each case exclusive of shares of Common
Stock sold directly or indirectly to such person by Keystone or any of its
affiliates; (iv) any person (other than Keystone or any of its affiliates) shall
have commenced a bona fide tender or exchange offer, or shall have filed an
application with an appropriate bank regulatory authority with respect to a
publicly announced offer, to purchase or acquire securities of the Corporation
such that, upon consummation of such offer, such person would own, control or
have the right to acquire 10% or more of the Common Stock (before giving effect
to any exercise of the Warrant); or (v) the Corporation or any Corporation
Subsidiary shall have entered into an agreement or other understanding with a
person (other than Keystone or any of its affiliates) for such person to
acquire, merge or consolidate with the Corporation or any Corporation Subsidiary
or to purchase or acquire all or substantially all of the assets of the
Corporation or any Corporation Subsidiary. As used in this Paragraph 2, "person"
and "beneficial ownership" shall have the same meanings as in the Warrant.

     Notwithstanding the foregoing, the Corporation shall not be obligated to
issue Shares upon exercise of the Warrant (i) in the absence of any required
governmental or regulatory approval or consent necessary for the Corporation to
issue the Shares or for Keystone to exercise the Warrant or prior to the
expiration or termination of any waiting period required by law or (ii) so long
as any injunction or other order, decree or ruling issued by any federal or
state court of competent jurisdiction is in effect which prohibits the sale or
delivery of the Shares. Keystone's right to exercise the Warrant shall terminate
and be of no further effect, except as to notices of exercise given prior
thereto, upon termination of the Warrant as provided in Paragraph 10 thereof.

     Any sale of the Warrant, in whole or in part, or any of the Shares by
Keystone, other than a registered public offering pursuant to Paragraph 3 hereof
or a sale to a majority-owned subsidiary of Keystone, shall be subject to the
right of first refusal of the Corporation (or any assignee or assignees of the
Corporation the identity of whom or which prior to the date thereof has been
given to Keystone) to purchase all, but not less than all, of the portion of the
Warrant or such Shares covered by Keystone's notice of its intention to make
such sale at a price equal to the written offer price which Keystone receives
from a third party (other than a majority-owned subsidiary of Keystone) and
intends to accept. The right of first refusal shall terminate 15 days after
notice of Keystone's intention to sell has been delivered to the Corporation. If
an offer is made for a consideration which in whole or in part consists of other
than cash, the value of the noncash portion of the consideration shall be
determined by a recognized investment banking firm selected jointly by Keystone
and the Corporation, and such determination shall in no event be made later than
the fifth day after notice of Keystone's intention to sell has been delivered to
the Corporation. In the event of the failure or refusal of the Corporation to
purchase the portion of the Warrant or all the Shares covered by Keystone's
notice of intention to sell, Keystone may, within 30 days from the date of such
notice, unless additional time is needed to give notification to or to obtain
approval from any governmental or regulatory authority and, if so required,
within 30 days after the date on which the required notification period has
expired or been terminated or such approval has been obtained and any requisite
waiting period with respect thereto has passed, sell all, but not less than all,
of the portion of the Warrant or such Shares covered by such notice to such
proposed transferee at no less than the price specified and on terms no more
favorable to the buyer than those set forth in the notice.

     3. If, at any time after the Warrant may be exercised or sold and on or
before June 30, 1999, the Corporation shall receive a written request therefor
from Keystone, the Corporation shall prepare, file and keep current a shelf
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), covering the Warrant and/or the Shares, and shall use its
 ----------
best efforts to cause such registration statement to become effective and remain
current for a period of not more than 245 days. Without the written consent of
Keystone, neither the Corporation nor any other holder of securities of the
Corporation

                                      -2-
<PAGE>
 
(other than any other holder who as of the date hereof has contractual right to
do so) may include securities in such registration statement. The Corporation
shall not be obligated to make effective more than one registration statement
pursuant to this Section 3.

     4. If and whenever the Corporation is required by the provisions of
Paragraph 3 hereof to effect the registration of any of the Securities under the
Securities Act, the Corporation will:

         (a) prepare and file with the Securities and Exchange Commission (the
    "SEC") such amendments to such registration statement and supplements to
     ---
    the prospectus contained therein as may be necessary to keep such
    registration statement current for a period of not more than 245 days;

         (b) furnish to Keystone and to Keystone's underwriters of the
    Securities being registered such reasonable number of copies of the
    registration statement, preliminary prospectus, final prospectus and such
    other documents as Keystone or such underwriters may reasonably request in
    order to facilitate the public offering of the Securities;

         (c) use its best efforts to register or qualify the Securities covered
    by such registration statement under such state securities or blue sky laws
    of such jurisdictions as Keystone or such underwriters may reasonably
    request; provided that the Corporation shall not be required by virtue
    hereof to submit to jurisdiction or to furnish a general consent to service
    of process in any state;

         (d) notify Keystone, promptly after the Corporation shall receive
    notice thereof, of the time when such registration statement has become
    effective or any supplement or amendment to any prospectus forming a part of
    such registration statement has been filed;

         (e) notify Keystone promptly of any request by the SEC for the amending
    or supplementing of such registration statement or prospectus or for
    additional information;

         (f) prepare and file with the SEC, promptly upon the request of
    Keystone, any amendments or supplements to such registration statement or
    prospectus which, in the opinion of counsel for Keystone and the
    Corporation, are required under the Securities Act or the rules and
    regulations promulgated thereunder in connection with the distribution of
    the Securities by Keystone;

         (g) prepare and promptly file with the SEC such amendment or supplement
    to such registration statement or prospectus as may be necessary to correct
    any statements or omissions if, at the time when a prospectus relating to
    such Securities is required to be delivered under the Securities Act, any
    event shall have occurred as the result of which such prospectus as then in
    effect would include an untrue statement of a material fact or omit to state
    any material fact necessary to make the statements therein, in the light of
    the circumstances in which they were made, not misleading;

         (h) advise Keystone, promptly after it shall receive notice or obtain
    knowledge, of the issuance of any stop order by the SEC suspending the
    effectiveness of such registration statement or the initiation or
    threatening of any proceeding for that purpose and promptly use its best
    efforts to prevent the issuance of any stop order or to obtain its
    withdrawal if such stop order should be issued; and

                                      -3-
<PAGE>
 
         (i) at the request of Keystone, furnish on the date or dates provided
    for in the underwriting agreement: (i) an opinion or opinions of counsel to
    the Corporation for the purposes of such registration, addressed to the
    underwriters and to Keystone, covering such matters as such underwriters and
    Keystone may reasonably request and as are customarily covered by issuer's
    counsel at that time; and (ii) a letter or letters from the independent
    certified public accountants of the Corporation, addressed to the
    underwriters and to Keystone, covering such matters as such underwriters or
    Keystone may reasonably request, in which letters such accountants shall
    state (without limiting the generality of the foregoing) that they are
    independent certified public accountants within the meaning of the
    Securities Act and that, in the opinion of such accountants, the financial
    statements and other financial data of the Corporation included in the
    registration statement or any amendment or supplement thereto comply in all
    material respects with the applicable accounting requirements of the
    Securities Act.

    5. With respect to the registration requested pursuant to Paragraph 3
hereof, the following fees, costs and expenses shall be borne by the
Corporation: All registration, filing and NASD fees, printing and engraving
expenses, fees and disbursements of the Corporation's counsel and accountants
and all legal fees and disbursements and other expenses of the Corporation to
comply with state securities or blue sky laws of any jurisdictions in which the
Securities to be offered are to be registered or qualified. Fees and
disbursements of counsel and accountants for Keystone, underwriting discounts
and commissions and transfer taxes for Keystone and any other expenses incurred
by Keystone shall be borne by Keystone.

    6. In connection with any registration statement:

         (a) The Corporation will indemnify and hold harmless Keystone, any
    underwriter (as defined in the Securities Act) for Keystone, and each
    person, if any, who controls Keystone or such underwriter (within the
    meaning of the Securities Act) from and against any and all loss, damage,
    liability, cost or expense to which Keystone or any such underwriter or
    controlling person may become subject under the Securities Act or otherwise,
    insofar as such loss, damage, liability, cost or expense arises out of or is
    caused by any untrue statement or alleged untrue statement of any material
    fact contained in such registration statement, any prospectus or preliminary
    prospectus contained therein or any amendment or supplement thereto, or
    arises out of or is based upon the omission or alleged omission to state
    therein a material fact required to be stated therein or necessary to make
    the statements therein, in the light of the circumstances in which they were
    made, not misleading; provided, however, that the Corporation will not be
                          --------  -------
    liable in any such case to the extent that any such loss, damage, liability,
    cost or expense arises out of or is based upon an untrue statement or
    alleged untrue statement or omission or alleged omission so made in
    conformity with information furnished by Keystone, such underwriter or such
    controlling person in writing specifically for use in the preparation
    thereof.

         (b) Keystone will indemnify and hold harmless the Corporation, any
    underwriter (as defined in the Securities Act), and each person, if any, who
    controls the Corporation or such underwriter (within the meaning of the
    Securities Act) from and against any and all loss, damage, liability, cost
    or expense to which the Corporation or any such underwriter or controlling
    person may become subject under the Securities Act or otherwise, insofar as
    such loss, damage, liability, cost or expense arises out of or is caused by
    any untrue or alleged untrue statement of any material fact contained in
    such registration statement, any prospectus or preliminary prospectus
    contained therein or any amendment or supplement thereto, or arises out of
    or is based upon the omission or the alleged omission to state therein a
    material fact required to be stated therein or necessary to make the
    statements therein, in the light of the circumstances in which they were
    made, not

                                      -4-
<PAGE>
 
    misleading, in each case to the extent, but only to the extent, that such
    untrue statement or alleged untrue statement or omission or alleged omission
    was so made in reliance upon and in conformity with written information
    furnished by Keystone specifically for use in the preparation thereof.

         (c) Promptly after receipt by an indemnified party pursuant to the
    provisions of subparagraph (a) or (b) of this Paragraph 6 of any claim in
    writing or of notice of the commencement of any action involving the subject
    matter of the foregoing indemnity provisions, such indemnified party will,
    if a claim in respect thereof is to be made against the indemnifying party
    pursuant to the provisions of said subparagraph (a) or (b), promptly notify
    the indemnifying party of the receipt of such claim or notice of the
    commencement of such action, but the omission to so notify the indemnifying
    party will not relieve it from any liability which it may otherwise have to
    any indemnified party hereunder. In case such action is brought against any
    indemnified party and it notifies the indemnifying party of the commencement
    thereof, the indemnifying party shall have the right to participate in, and,
    to the extent that it may wish, jointly with any other indemnifying party
    similarly notified, to assume the defense thereof, with counsel satisfactory
    to such indemnified party; provided, however, that if the defendants in any
                               --------  -------
    action include both the indemnified party and the indemnifying party and
    there is a conflict of interest which would prevent counsel for the
    indemnifying party from also representing the indemnified party, the
    indemnified party or parties shall have the right to select one separate
    counsel to participate in the defense of such indemnified party or parties.
    After notice from the indemnifying party to such indemnified party of its
    election so to assume the defense thereof, the indemnifying party will not
    be liable to such indemnified party pursuant to the provisions of said
    subparagraph (a) or (b) for any legal or other expenses subsequently
    incurred by such indemnified party in connection with the defense thereof
    other than reasonable costs of investigation, unless (i) the indemnified
    party shall have employed counsel in accordance with the provisions of the
    preceding sentence, (ii) the indemnifying party shall not have employed
    counsel reasonably satisfactory to the indemnified party to represent the
    indemnified party within a reasonable time after the notice of the
    commencement of the action, or (iii) the indemnifying party has authorized
    the employment of counsel for the indemnified party at the expense of the
    indemnifying party.

         (d) If recovery is not available under the foregoing indemnification
    provisions, for any reason other than as specified therein, the parties
    entitled to indemnification by the terms thereof shall be entitled to
    contribution to liabilities and expenses, except to the extent that
    contribution is not permitted under Section 11(f) of the Securities Act. In
    determining the amount of contribution to which the respective parties are
    entitled, there shall be considered the parties' relative knowledge and
    access to information concerning the matter with respect to which the claim
    was asserted, the opportunity to correct and/or prevent any statement or
    omission, and any other equitable considerations appropriate under the
    circumstances. Keystone and the Corporation agree that it would not be
    equitable if the amount of such contribution were determined by pro rata or
    per capita allocation even if the underwriters and Keystone as a group were
    considered a single entity for such purpose.

    7. Subject to applicable regulatory restrictions, from and after the date on
which any event described in the second paragraph of this Paragraph 7 occurs,
the Holder as defined in the Warrant (which shall include a former Holder) who
has exercised the Warrant in whole or in part shall have the right to require
the Corporation to redeem some or all of the Shares at a redemption price per
share (the "Redemption Price") equal to the highest of (i) 110% of the Exercise
            ---------- -----
Price, (ii) the highest price paid or agreed to be paid for any share of Common
Stock by an Acquiring Person (as defined in the Warrant) during the twelve
months immediately preceding the date notice of the election to require
redemption

                                      -5-
<PAGE>
 
is given by the Holder under the third paragraph of this Paragraph 7 (as
appropriately adjusted to reflect any of the events described in Paragraph 7(A)
of the Warrant) and (iii) in the event of a sale of all or substantially all of
the Corporation's assets, any Corporation Subsidiary or all or substantially all
of any Corporation Subsidiary's assets, (x) the sum of the price paid in such
sale for such assets and the current market value of the remaining assets of the
Corporation as determined by a recognized investment banking firm selected by
such Holder, divided by (y) the number of shares of Common Stock then
outstanding. If the price paid consists in whole or in part of securities or
assets other than cash, the value of such securities or assets shall be their
then current market value as determined by a recognized investment banking firm
selected by the Holder. The Holder's right to require the Corporation to redeem
some or all of the Shares under this Paragraph 7 shall expire at the close of
business on the later of (1) the 180th day following the occurrence of any event
described in the second paragraph of this Paragraph 7 and (2) July 19, 1998.

     The redemption rights provided in this Paragraph 7 shall become exercisable
upon the occurrence of any of the following events: (i) the acquisition by any
person (other than Keystone or any subsidiary of Keystone) of beneficial
ownership of 50% or more of the Common Stock (before giving effect to any
exercise of the Warrant) exclusive of shares of Common Stock sold directly or
indirectly to such person by Keystone or (ii) a transaction of the type
specified in Paragraph 2(v) shall have been consummated. As used in this
Paragraph 7 "person" and "beneficial ownership" shall havethe same meanings as 
             ------       ---------- ---------
in the Warrant.

     The Holder may exercise its right to require the Corporation to redeem some
or all of the Shares pursuant to this Paragraph 7 by surrendering for such
purpose to the Corporation at its principal office, within the time period
specified in the second preceding paragraph, a certificate or certificates
representing the number of Shares to be redeemed accompanied by a written notice
stating that it elects to require the Corporation to redeem all or a specified
number of such Shares in accordance with the provisions of this Paragraph 7. As
promptly as practicable, and in any event within five business days after the
surrender of such certificates and the receipt of such notice relating thereto,
the Corporation shall deliver or cause to be delivered to the Holder the
applicable Redemption Price for the Shares which it is not then prohibited under
applicable law or regulation from redeeming, and, if the Holder has given the
Corporation notice that less than the full number of Shares evidenced by the
surrendered certificate or certificates are to be redeemed, a new certificate or
certificates, of like tenor, for the number of Shares evidenced by such
surrendered certificate or certificates, less the number of Shares redeemed. To
the extent that the Corporation is prohibited under applicable law or
regulation, or by judicial or administrative action, from redeeming all of the
Shares as to which the Holder has given notice to redeem hereunder, the
Corporation shall immediately notify the Holder and thereafter deliver or cause
to be delivered to the Holder the applicable Redemption Price for such number of
the Shares as it is not prohibited from redeeming within five business days
after the date on which the Corporation is no longer so prohibited; provided,
                                                                    --------
however, that, at the option of Keystone, at any time after receipt of such
- -------
notice from the Corporation, the Corporation shall deliver to the Holder a
certificate for such number of the Shares as it is then prohibited from
redeeming, or, at the Holder's option, all the Shares, and the Corporation shall
have no further obligation to redeem such Shares.

    8. In the event that the Corporation issues any additional shares of Common
Stock after the date of this Agreement, the Corporation shall issue additional
warrants to Keystone, such that, after such issuance, the number of shares of
Common Stock subject to all warrants hereunder, together with any shares of
Common Stock previously issued pursuant hereto, equals 19.9% of the sum of (1)
the number of shares of Common Stock issued and outstanding following such
issuance and (2) the number of shares of Common Stock subject to all warrants
hereunder. Such additional warrants shall be identical to the Warrant.

                                      -6-
<PAGE>
 
    9. The Corporation will not enter into any transaction described in (a), (b)
or (c) of Paragraph 6(A) of the Warrant unless the Acquiring Corporation (as
defined in the Warrant) assumes in writing, in form and substance satisfactory
to the Holder, all the obligations of the Corporation hereunder.

    10. If Keystone acquires Shares and, during the period ending on the later
of (1) one year after the date of such acquisition or (2) June 19, 1998 the
merger contemplated by the Plan has not been completed, then, during the thirty-
day period commencing at the expiration of such period the Corporation shall
have the right to repurchase all (but not less than all) of such Shares of
Common Stock so acquired by Keystone and held by Keystone at the time of such
repurchase at a price equal to the sum of (a)(i) the greater of the current
market price or the Exercise Price paid for such Shares, multiplied by (ii) the
number of such Shares so acquired, plus (b) Keystone's after-tax carrying cost.
For the purposes of this calculation, the "current market price" shall mean the
average of the closing sale prices for the Common Stock for the 25 trading days
immediately preceding the repurchase, as quoted on the NASDAQ National Market
System, and Keystone's pre-tax carrying cost shall be equal to interest on the
Exercise Price paid for such Shares so purchased from the date of purchase at
the prime rate of interest established by Mellon Bank, N.A. as in effect
throughout such period, less any dividends received on such Shares so purchased.

    11. To the extent that Keystone acquires Shares, and until the Corporation's
rights (if any) to redeem such Shares pursuant to Paragraph 10 of this Agreement
have expired, Keystone agrees to vote such Shares in accordance with the
recommendation of the Board of Directors of the Corporation so long as at least
a majority of such Board of Directors is the same as on the date hereof, except
as to voting in connection with mergers, acquisitions, liquidations or sales or
other dispositions of assets involving the Corporation or any Corporation
Subsidiary, in which instance no such restrictions shall apply, provided,
however, that the covenant contained in this Paragraph 11 shall not apply to any
Holder other than Keystone or one of its subsidiaries.

    12. Without limiting the foregoing or any remedies available to Keystone, it
is specifically acknowledged that Keystone would not have an adequate remedy at
law for any breach of this Agreement and will be entitled to specific
performance of the obligations under, and injunctive relief against actual or
threatened violations of the obligations of any person subject to, this
Agreement.

    IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
executed in counterparts by their duly authorized officers and their corporate
seals to be hereunto affixed, all as of the day and year first above written.

                                    WARRANT
                     to Purchase up to 2,113,706 Shares of

                              Financial Trust Corp

    This is to certify that, for value received, FINANCIAL, INC. ("Keystone") or
                                                                   --------
any permitted transferee (Keystone or such transferee hereinafter called the

 ------
of the Agreement (as hereinafter defined), from FINANCIAL TRUST CORP (the
"Corporation"), at any time on or after the date hereof, an aggregate of up to
 -----------
2,113,706 fully paid and nonassessable shares of common stock, par value $5.00

$43.725, subject to adjustment as herein provided (the "Exercise Price").
                                                        -------- -----

    1. Exercise of Warrant. Subject to the provisions hereof and the limitations
       ------------------- 
set forth in Paragraph 2 of an Investment Agreement dated as of December 19,
1996 by and between Keystone and the Corporation (the "Agreement") executed and
                                                       ---------
delivered in connection with an Agreement and Plan of Reorganization and an
Agreement and Plan of Merger dated as of December 19, 1996 between Keystone and
the Corporation (collectively, the "Plan"), this Warrant may be exercised at any
                                    ----
time or from time to time on or after the date hereof. This Warrant shall be
exercised by presentation and surrender hereof to the Corporation at the
principal office of the Corporation, accompanied by (i) a written notice of
exercise, (ii) payment to the Corporation, for the account of the Corporation,
of the Exercise Price for the number of shares of Common Stock specified in such
notice and (iii) a certificate of the Holder specifying the event or events
which have occurred which entitle the Holder to exercise this Warrant. The
Exercise Price for the number of shares of Common Stock specified in the notice
shall be payable in immediately available funds. This Warrant may not be
exercised in part for less than 250,000 shares, except (i) for an initial
exercise resulting in ownership of approximately 5% of the outstanding shares of
Common Stock after giving effect to the exercise, (ii) as limited by applicable
law, regulation or regulatory order or (iii) when this Warrant becomes
exercisable for less than 250,000 shares, the remaining shares for which it is
then exercisable.

    Upon such presentation and surrender, the Corporation shall issue promptly
(and within two business days if requested by the Holder) to the Holder or its
assignee, transferee or designee the shares of Common Stock to which the Holder
is entitled hereunder.

    If this Warrant should be exercised in part only, the Corporation shall,
upon surrender of this Warrant for cancellation, execute and deliver a new
Warrant evidencing the rights of the Holder thereof to purchase the balance of
the shares of Common Stock purchasable hereunder. Upon receipt by the
Corporation of this Warrant, in proper form for exercise, the Holder shall be
deemed to be the holder of record of the shares of Common Stock issuable upon
such exercise, notwithstanding that the stock transfer books of the Corporation
may then be closed or that certificates representing such shares of Common Stock
shall not then be actually delivered to the Holder. The Corporation shall pay
all expenses, and any and all United States federal, state and local taxes and
other charges, that may be payable in connection with the preparation, issue and
delivery of stock certificates pursuant to this Paragraph 1 in the name of the
Holder or its assignee, transferee or designee.

<PAGE>
 
    2. Reservation of Shares; Preservation of Rights of Holder. The Corporation
       -------------------------------------------------------
shall at all times while this Warrant is outstanding and unexercised maintain
and reserve, free from preemptive rights, such number of authorized but unissued
or treasury shares of Common Stock as may be necessary so that this Warrant may
be exercised without additional authorization of Common Stock after giving
effect to all other options, warrants, convertible securities and other rights
to acquire shares of Common Stock at the time outstanding. The Corporation
further agrees (i) that it will not, by charter amendment or through
reorganization, consolidation, merger, dissolution or sale of assets, or by any

    4. Exchange, Transfer or Loss of Warrant. This Warrant is exchangeable or,
       -------------------------------------
subject to Paragraph 2 of the Investment Agreement, transferable, without
expense, at the option of the Holder, upon presentation and surrender hereof at
the principal office of the Corporation for other Warrants of different
denominations entitling the Holder to purchase in the aggregate the same number
of shares of Common Stock purchasable hereunder. The term "Warrant" as used
                                                           -------

surrender and cancellation of this Warrant, if mutilated, the Corporation will
execute and deliver a new Warrant of like tenor and date.

    This Warrant may not be exercised or sold except in accordance with the
terms of the Agreement.

    5. Redemption. (A) Subject to applicable regulatory restrictions, from and
       ----------
after the date on which any event described in the second paragraph of Paragraph
7 of the Agreement occurs, the Holder shall have the right to require the
Corporation to redeem this Warrant at a redemption price (the "Redemption
                                                               ----------
Amount") equal to the highest of (i) the number of shares of Common Stock for
- ------
which this Warrant is then exercisable (the "Conversion Number") multiplied by
                                             ---------- ------
the Exercise Price multiplied by .10, (ii)(x) the highest price paid or agreed
to be paid for any share of Common Stock by the Acquiring Person (as hereinafter
defined) during the twelve months immediately preceding the date notice of the
election to require redemption is given by the Holder under Paragraph 5(B) (such
price to be appropriately adjusted to reflect the effect of any of the events
described in Paragraph 7(A) hereof), less the Exercise Price, multiplied by (y)
the Conversion Number, and (iii) in the event of the sale of all or
substantially

                                      A-2
<PAGE>
 
all of the assets of the Corporation, any Corporation Subsidiary (as defined in
the Agreement) or all or substantially all of the assets of any Corporation
Subsidiary, the Conversion Number multiplied by (x)(I) the sum of (a) the price
paid for such assets, (b) the current market value of the remaining assets of
the Corporation, as determined by a recognized investment banking firm selected
by the Holder, and (c) the Exercise Price multiplied by the Conversion Number,
divided by (II) the sum of the number of shares of Common Stock then outstanding
and the Conversion Number, less (y) the Exercise Price. If, for the purpose of
this calculation or calculating the Assigned Value (as hereinafter defined), the
price paid consists in whole or in part of securities or assets other than cash,
the value of such securities or assets shall be their then current market value
as determined by a recognized investment banking firm selected by the Holder.
The Holder's right to require the Corporation to redeem this Warrant under this
Paragraph 5 shall expire at the close of business on the later of (1) the 180th
day following the occurrence of any event described in the second paragraph of
Paragraph 7 of the Agreement and (2) July 19, 1998.
                                       
         (B) The Holder of this Warrant may exercise its right to require the
Corporation to redeem this Warrant pursuant to this Paragraph 5 by surrendering
for such purpose to the Corporation, at its principal office, within the period
specified above, this Warrant accompanied by a written notice stating that the
Holder elects to require the Corporation to redeem this Warrant in accordance
with the provisions of this Paragraph 5. As promptly as practicable, and in any
event within ten business days after the surrender of this Warrant and the
receipt of such notice relating thereto, the Corporation shall deliver or cause
to be delivered to the Holder the Redemption Amount therefor or the portion
thereof which it is not then prohibited under applicable law and regulation from
delivering to the Holder.

         To the extent that the Corporation is prohibited under applicable law
or regulation, or as a result of administrative or judicial action, from
redeeming this Warrant in full, the Corporation shall immediately notify the
Holder and thereafter deliver or cause to be delivered to the Holder the portion
of the Redemption Amount which it is no longer prohibited from delivering to the
Holder within five business days after the date on which the Corporation is no
longer so prohibited; provided, however, that, at the option of the Holder, at
                      --------  -------
any time after receipt of such notice, the Corporation shall deliver to the
Holder a new Warrant evidencing the right of the Holder to purchase that number
of shares of Common Stock obtained by multiplying the Conversion Number in
effect at such time by a fraction, the numerator of which is the Redemption
Amount less the portion thereof (if any) theretofore delivered to the Holder and
the denominator of which is the Redemption Amount, and the Corporation shall
have no further obligation to redeem such new Warrant.

         (C) As used in this Warrant the following terms have the meanings
indicated:

              (a) "Acquiring Person" shall mean any "Person" (hereinafter

                                       ----------------
                   (i) which such Person or any of its "Affiliates" (as
hereinafter defined) or "Associates" (as hereinafter defined) beneficially owns,
directly or indirectly; and
                                    
                   (ii) which such Person or any of its Affiliates or Associates
has (1) the right to acquire (whether such right is exercisable immediately or
only after the passage of time or

                                      A-3
<PAGE>
 
otherwise) pursuant to any agreement, arrangement or understanding or upon the
exercise of conversion rights, exchange rights, warrants or options, or
otherwise, or (2) the right to vote pursuant to any agreement, arrangement or
understanding; and

              (d) "Affiliate" and "Associate" shall have the respective meanings
                   ---------       ---------
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations
promulgated under the Securities Exchange Act of 1934, as amended, as in effect
on the date of the Agreement.

    6. Certain Transactions. (A) In case the Corporation (a) shall consolidate
       --------------------
with or merge into any Person, other than the Holder or one of its Affiliates,
and shall not be the continuing or surviving corporation of such consolidation
or merger, (b) shall permit any Person, other than the Holder or one of its
Affiliates, to merge into the Corporation and the Corporation shall be the
continuing or surviving corporation, but, in connection with such merger, the
then outstanding shares of Common Stock shall be changed into or exchanged for
stock or other securities of any other Person or cash or any other property or
shall represent less than 50% of the shares of Common Stock immediately after
giving effect to the merger, or (c) shall sell or otherwise transfer all or
substantially all of its assets, any Corporation Subsidiary or all substantially
all of the any Corporation Subsidiary's assets to any Person, other than the
Holder or one of its Affiliates, then, and in each such case, the agreement
governing such transaction shall make proper provision so that this Warrant
shall (at the option of the Holder, in whole or in part), upon the consummation
of any such transaction and upon the terms and conditions set forth herein, be
converted into, or exchanged for, a warrant, at the option of the Holder, of
either (I) the Acquiring Corporation (as hereinafter defined), (II) any company
which controls the Acquiring Corporation, or (III) in the case of a merger
described in clause (A)(b), the Corporation, in which case such warrant shall be
a newly issued warrant (in any such case, the "Substitute Warrant").
                                               ---------- -------

         (B) The following terms have the meanings indicated:

               (a) "Acquiring Corporation" shall mean (I) the continuing or
                    ---------------------
surviving corporation of a consolidation or merger with the Corporation (if
other than the Corporation), (II) the corporation merging into the Corporation
in a merger in which the Corporation is the continuing or surviving person and
in connection with which the then outstanding shares of Common Stock are changed
into or exchanged for stock of other securities of any other Person or cash or
any other property or shall represent less than 50% of the shares of Common
Stock immediately after giving effect to the merger, and (III) the transferee of
all or substantially all of the Corporation's assets, any Corporation Subsidiary
or all or substantially all of any Corporation Subsidiary's assets;


              (b) "Substitute Common Stock" shall mean the common stock issued
                   -----------------------
by the issuer of the Substitute Warrant;

              (c) "Assigned Value" shall mean the Redemption Price per share of
                   --------------
Common Stock (as defined in Paragraph 7 of the Agreement) multiplied by
the Conversion Number; 

              (d) "Average Price" shall mean the average closing price (or if
                   -------------
unavailable, the average of the daily averages of the closing bid and asked
prices) of a share of Substitute Common Stock for the one year immediately
preceding the consolidation, merger or sale in question, but in no event higher
than the closing price (or average of the closing bid and asked prices) of a
share of Substitute Common Stock on the day preceding such consolidation, merger
or sale; provided that if the Corporation is the issuer of the Substitute
Warrant, the Average Price shall be computed with respect to a share of the
common stock issued by the Person merging into the Corporation or by

                                      A-4
<PAGE>
 
by any company which controls such Person, as the Holder may elect. If the
Average Price cannot be computed as aforesaid because neither closing prices nor
closing bid and asked prices are available for such one-year period, then the
Average Price shall be the average fair market value of a share of Substitute
Common Stock for such period (but in no event higher than the fair market value
on the day preceding such consolidation, merger or sale) as determined by a
recognized investment banking firm selected by Keystone.

         (C) The Substitute Warrant shall have the same terms as this Warrant
provided that if the terms of the Substitute Warrant cannot, for legal reasons,
be the same as this Warrant, such terms shall be as similar as possible and in
no event less advantageous to the Holder. The issuer of the Substitute Warrant
shall also enter into an agreement with the then Holder of the Substitute
Warrant in substantially the same form as the Agreement, which shall be
applicable to the Substitute Warrant. For purposes of the Substitute Warrant and
such agreement, any event referred to in Paragraph 2 or Paragraph 7 of the
Agreement shall be deemed to have occurred when it occurred with respect to the
Corporation.

         (D) The Substitute Warrant shall be immediately exercisable for such
number of shares of Substitute Common Stock as is equal to the Assigned Value
divided by the Average Price. The exercise price of the Substitute Warrant per
share of Substitute Common Stock shall be equal to the Exercise Price multiplied
by a fraction in which the numerator is the Conversion Number and the
denominator is the number of shares of Substitute Common Stock for which the
Substitute Warrant is exercisable.

         (E) In no event, pursuant to any of the foregoing paragraphs, shall
the Substitute Warrant be exercisable for more than 19.9% of the aggregate of
the outstanding shares of Substitute Common Stock and the shares of Substitute
Common Stock issuable upon exercise of the Substitute Warrant.

     7. Adjustment. The number of shares of Common Stock purchasable upon the
        ----------
exercise of this Warrant and the Exercise Price shall be subject to adjustment
from time to time as provided in this Paragraph 7:

         (A)(1) In case the Corporation shall pay or make a dividend or other
distribution on any class of capital stock of the Corporation in Common Stock,
the number of shares of Common Stock purchasable upon exercise of this Warrant
shall be increased by multiplying such number of shares by a fraction of which
the denominator shall be the number of shares of Common Stock outstanding at the
close of business on the day immediately preceding the date of such distribution
and the numerator shall be the sum of such number of shares and the total number
of shares constituting such dividend or other distribution, such increase to
become effective immediately after the opening of business on the day following
such distribution, provided, however, that in no event shall the Warrant be
                   --------  -------
exercised for more than 19.9% of the shares of Common Stock issued and
outstanding following such exercise.

         (2) In case outstanding shares of Common Stock shall be subdivided into
a greater number of shares of Common Stock, the number of shares of Common Stock
purchasable upon exercise of this Warrant at the opening of business on the day
following the day upon which such subdivision becomes effective shall be
proportionately increased, and, conversely, in case outstanding shares of Common
Stock shall each be combined into a smaller number of shares of Common Stock,
the number of shares of Common Stock purchasable upon exercise of this Warrant
at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately decreased, such increase
or decrease, as the case may be, to become effective immediately after the
opening of business on the day following the day

                                      A-5
<PAGE>
 
upon which such subdivision or combination becomes effective, provided, 
                                                              --------
however, that in no event shall the Warrant be exercised for more than
- -------
19.9% of the shares of Common Stock issued and outstanding following such
exercise.

         (3) The reclassification (excluding any transaction in which a
Substitute Warrant would be issued) of Common Stock into securities (other than
Common Stock) and/or cash and/or other consideration shall be deemed to involve
a subdivision or combination, as the case may be, of the number of shares of
Common Stock outstanding immediately prior to such reclassification into the
number or amount of securities and/or cash and/or other consideration
outstanding immediately thereafter and the effective date of such
reclassification shall be deemed to be "the day upon which such subdivision
becomes effective", or "the day upon which such combination becomes effective",
as the case may be, within the meaning of clause (2) above.

         (4) The Corporation may make such increases in the number of shares of
Common Stock purchasable upon exercise of this Warrant, in addition to those
required by this subparagraph (A), as shall be determined by its Board of
Directors to be advisable in order to avoid taxation so far as practicable of
any dividend of stock or stock rights or any event treated as such for federal
income tax purposes to the recipients.

         (B) Whenever the number of shares of Common Stock purchasable upon
exercise of this Warrant is adjusted as herein provided, the Exercise Price
shall be adjusted by a fraction in which the numerator is equal to the number of
shares of Common Stock purchasable prior to the adjustment and the denominator
is equal to the number of shares of Common Stock purchasable after the
adjustment.

         (C) For the purpose of this Paragraph 7, the term "Common Stock" shall
include any shares of the Corporation of any class or series which has no
preference or priority in the payment of dividends or in the distribution of
assets upon any voluntary or involuntary liquidation, dissolution or winding up
of the Corporation and which is not subject to redemption by the Corporation.

      8. Notice. (A) Whenever the number of shares for which this Warrant is
         ------  
exercisable is adjusted as provided in Paragraph 7, the Corporation shall
promptly compute such adjustment and mail to the Holder a certificate, signed by
a principal financial officer of the Corporation, setting forth the number of
shares of Common Stock for which this Warrant is exercisable as a result of such
adjustment, a brief statement of the facts requiring such adjustment and the
computation thereof and when such adjustment will become effective.

         (B) Upon the occurrence of any event which results in this Warrant
becoming redeemable, as provided in Paragraph 5, the Corporation shall promptly
notify the Holder of such event; and promptly compute the Redemption Amount and
furnish to the Holder a certificate, signed by a principal financial officer of
the Corporation, setting forth the Redemption Amount and the basis and
computation thereof.  

         (C) Upon the occurrence of an event which results in this Warrant
becoming convertible into, or exchangeable for, the Substitute Warrant, as
provided in Paragraph 6, the Acquiring Corporation and the Corporation shall
promptly notify the Holder of such event; and, upon receipt from the Holder of
its choice as to the issuer of the Substitute Warrant, the Acquiring Corporation
and the Corporation shall promptly compute the number of shares of Substitute
Common Stock for which the Substitute Warrant is exercisable and furnish to the
Holder a certificate, signed by a principal financial officer of each of the
Acquiring

                                      A-6
<PAGE>
 
Corporation and the Corporation, setting forth the number of shares of
Substitute Common Stock for which the Substitute Warrant is exercisable, a
computation thereof and when such adjustment will become effective.

    9. Rights of the Holder. (A) Without limiting the foregoing or any remedies
       --------------------
available to the Holder, it is specifically acknowledged that the Holder would
not have an adequate remedy at law for any breach of the provision of this
Warrant and will be entitled to specific performance of the obligations under,
and injunctive relief against actual or threatened violations of the obligations
of any Person subject to, this Warrant.

         (B) Except as provided in the third paragraph of Paragraph 1 hereof,
the Holder shall not, by virtue hereof, be entitled to any rights of a
shareholder in the Corporation.

      10. Termination. This Warrant and the rights conferred hereby shall
          -----------
terminate (i) upon a willful breach of the Agreement by Keystone, (ii) at the
Effective Time of the Merger pursuant to the Plan, (iii) upon a valid
termination of the Plan prior to the occurrence of an event described in
Paragraph 2 of the Agreement or (iv) upon the failure of the shareholders of the
Corporation to approve the Merger by the required vote at a meeting duly called
and held in accordance with the requirements of Section 6.03 of the Agreement
and Plan of Reorganization prior to the occurrence of an event described in
Paragraph 2 of the Agreement and (v) to the extent this Warrant has not
previously been exercised, at the close of business on the later of (A) July 19,
1998 and (B) 12 months after the occurrence of an event described in Paragraph 2
of the Agreement, provided that such termination pursuant to this clause (v)
shall not affect any redemption under Paragraph 5 as to which exercise under
Paragraph 5(B) has previously occurred.

    11. Securities Act Representation. The Holder, by acceptance hereof, agrees
        -----------------------------
that, unless the shares of Common Stock issuable upon exercise hereof have been
registered under the Securities Act of 1933, as amended, (the "Securities Act")
                                                               --------------
and any other applicable securities laws for sale or other disposition by the
Holder, it will deliver to the Corporation upon the exercise hereof a written
representation that it is acquiring the shares of Common Stock issuable upon the
exercise hereof solely for its own account and not with a view to the
distribution thereof within the meaning of the Securities Act and that any
certificate or certificates representing such shares may bear a legend to the
effect that such shares may not be sold except pursuant to an effective
registration statement under the Securities Act or any exemption from
registration thereunder and registration or qualification under any other
applicable securities laws or exemptions therefrom.

    12. Governing Law. This Warrant shall be governed by, and interpreted in
        -------------
accordance with, the substantive laws of the Commonwealth of Pennsylvania.

Keystone Financial, Inc.
One Keystone Plaza
Front & Market Streets
P.O. Box 3660
Harrisburg, PA 17105-3660

Gentlemen:

     The undersigned understands that Keystone Financial, Inc. ("Keystone") is
about to enter into an Agreement and Plan of Reorganization and an Agreement and
Plan of Merger (collectively, the "Merger Agreements") with Financial Trust Corp
("FTC"). The Merger Agreements provide for the merger of FTC into Keystone (the
"Merger") and the conversion of outstanding shares of FTC Common Stock into
Keystone Common Stock in accordance with the formula therein set forth.

     In order to induce Keystone to enter into the Merger Agreements, and
intending to be legally bound hereby, the undersigned represents, warrants and
agrees that at the FTC Shareholders' Meeting contemplated by Section 6.3 of the
Agreement and Plan of Reorganization and any adjournment thereof the undersigned
will, in person or by proxy, vote or cause to be voted in favor of the Merger
Agreements and the Merger the shares of FTC Common Stock beneficially owned by
the undersigned individually or, to the extent of the undersigned's
proportionate voting interest, jointly with other persons, as well as (to the
extent of the undersigned's proportionate voting interest) any other shares of
FTC Common Stock over which the undersigned may hereafter acquire beneficial
ownership in such capacities (collectively, the "Shares"). Subject to the final
paragraph of this agreement, the undersigned further agrees that he will use his
best efforts to cause any other shares of FTC Common Stock over which he has or
shares voting power to be voted in favor of the Merger Agreements and the
Merger.

     The undersigned further represents, warrants and agrees that until the
earlier of (i) the consummation of the Merger or (ii) the termination of the
Merger Agreements in accordance with their terms, the undersigned will not,
directly or indirectly:

         (a) vote any of the Shares, or cause or permit any of the Shares to be
     voted, in favor of any other merger, consolidation, plan of liquidation,
     sale of assets, reclassification or other transaction involving FTC or any
     of its subsidiaries which would have the effect of any person other than
     Keystone or an affiliate acquiring control over FTC, any of its
     subsidiaries or any substantial portion of the assets of FTC or any of its
     subsidiaries. As used herein, the term "control" means (1) the ability to
     direct the voting of 10% or more of the outstanding voting securities of a
     person having ordinary voting power in the election of directors or in the
     election of any other body having similar functions or (2) the ability to
     direct the management and policies of a person, whether through ownership
     of securities, through any contract, arrangement or understanding or
     otherwise.
<PAGE>
 
          (b) sell or otherwise transfer any of the Shares, or cause or permit
     any of the Shares to be sold or otherwise transferred (i) pursuant to any
     tender offer, exchange offer or similar proposal made by any person other
     than Keystone or an affiliate, (ii) to any person seeking to obtain control
     of FTC, any of its subsidiaries or any substantial portion of the assets of
     FTC or any of its subsidiaries or to any other person (other than Keystone
     or an affiliate) under circumstances where such sale or transfer may
     reasonably be expected to assist a person seeking to obtain such control or
     (iii) for the principal purpose of avoiding the obligations of the
     undersigned under this agreement.

     It is understood and agreed that this agreement relates solely to the
capacity of the undersigned as a shareholder or other beneficial owner of the
Shares and is not in any way intended to affect the exercise by the undersigned
of the undersigned's responsibilities as a director or officer of FTC or any of
its subsidiaries. It is further understood and agreed that the term "Shares"
shall not include any securities beneficially owned by the undersigned as a
trustee or fiduciary, and that this agreement is not in any way intended to
affect the exercise by the undersigned of the undersigned's fiduciary
responsibility in respect of any such securities.


                                   Very truly yours,



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

                              EMPLOYMENT AGREEMENT


   THIS AGREEMENT, made and entered into this 19th day of December, 1996, by
and between KEYSTONE FINANCIAL, INC. ("Keystone"), and RAY L. WOLFE, of 
Carlisle, Pennsylvania ("Mr. Wolfe").

                              W I T N E S S E T H:

   WHEREAS, Keystone and Financial Trust Corp have entered into an Agreement and
Plan of Reorganization and an Agreement and Plan of Merger (collectively, the
"Agreements") whereby, at the "Effective Time" (as described in the Agreements),
Financial Trust Corp will merge with and into Keystone, and

   WHEREAS,  Mr. Wolfe is currently employed by Financial Trust Corp as it's
Chairman and Chief Executive Officer and possesses valuable knowledge and skills
that have contributed to the successful operation of Financial Trust Corp, and

   WHEREAS, subsequent to the closing of the transaction contemplated by the
Agreements, Keystone desires to employ Mr. Wolfe and Mr. Wolfe is willing to
become employed by Keystone.

   NOW, THEREFORE, in consideration of the following rights and benefits and
intending to be legally bound, Keystone agrees to employ Mr. Wolfe, and Mr.
Wolfe hereby agrees to serve Keystone, upon the following terms and conditions:

   1.  Term.  Mr. Wolfe's employment by Keystone shall commence as of the
Effective Time and shall continue thereafter for a period of three (3) years,
subject to the extension described in Paragraph 6 hereof.

   2. Office.  Effective as of the Effective Time and continuing until the
Annual Meeting of Keystone in 1998, Keystone agrees to employ Mr. Wolfe as its
Chairman. Thereafter, Mr. Wolfe agrees to serve Keystone in such senior
executive capacities as may be mutually agreed upon from time to time by the
Chief Executive Officer of Keystone and Mr. Wolfe. Mr. Wolfe shall use his best
energies and abilities in the performance of his duties hereunder.

   3.  Compensation.  During the term of employment described in Paragraph 1,
Keystone shall pay Mr. Wolfe an all inclusive, aggregate annual amount of Three
Hundred and Fifty Thousand Dollars ($350,000). Such amount shall be inclusive of
any amounts which would have currently been paid to Mr. Wolfe but for his
election to have such amounts deferred to a later date under the terms of a non-
qualified deferral arrangement offered by Keystone, as well as any contributions
Keystone shall be required to contribute as "matching" contributions to any plan
or arrangement, qualified or nonqualified, in which Mr. Wolfe may participate
from time to time.

   4.  Benefits.  During the term of his employment hereunder, Mr. Wolfe shall
be covered by such life, health, major medical, disability and other welfare
benefit plans and any pension, profit sharing or similar qualified retirement
plans as are available generally to employees of Keystone. Keystone shall
reimburse Mr. Wolfe for all reasonable and customary out-of-pocket expenses
incurred by him in the
<PAGE>
 
ordinary course of Keystone's business as are provided to senior executive
employees of Keystone, including the use of an automobile and the payment of
dues for membership in one local country club.

   5.  Termination of Employment.  This Agreement, and the compensation and
benefits described herein may not be terminated by Keystone except for a breach
of the provisions of Paragraph 7 hereof. However, in the event of Mr. Wolfe's
death, total and permanent disability or other substantial incapacity which is
reasonably expected to be of more than six months duration, Mr. Wolfe's
employment shall be terminated at the end of the month in which such death
occurred or a permanent disability or substantial incapacity was determined to
exist by Keystone. Permanent disability or substantial incapacity shall be
conclusively established by Mr. Wolfe's qualification for benefits under
Keystone's long term disability plan or qualification for Social Security
disability benefits and may be determined by an express finding of permanent
disability or substantial incapacity by the Board of Directors. Upon the
occurrence of Mr. Wolfe's death or the determination of Mr. Wolf's' permanent
disability or substantial incapacity, this Agreement shall immediately terminate
and Keystone shall be released from all further responsibilities hereunder.

   6.  Extension of Term; Stand-by Consulting Agreement.  Acknowledging Mr.
Wolfe's extensive knowledge and highly valuable skills, Keystone desires to have
the opportunity to call on such knowledge and skills from time to time during
the period beginning at the end of the initial term of employment described in
Paragraph 1 and ending upon Mr. Wolfe's sixty-fifth (65th) birthday.
Accordingly, Mr. Wolfe agrees to make himself available to advise and consult
with Keystone from time to time during this extended term, upon reasonable
advance notice from Keystone. In consideration of Mr. Wolfe's agreement to make
himself available as described herein, Keystone shall compensate Mr. Wolf at a
rate of One Hundred and Seventy Seven Thousand Dollars ($177,000) per annum, and
provide Mr. Wolf with Keystone's regular medical care benefits during such
period. The payment by Keystone of such compensation and benefits are subject to
the provisions of Paragraph 7. Mr. Wolfe shall be considered an employee of
Keystone during this period and all federal, state and local income and
employment tax withholding and payments shall be made.

   7.  Acceleration of Payments Upon a "Change of Control". Upon the
occurrence of a "Change of Control" (as defined below) during the initial or
extended term of this agreement, Mr. Wolfe shall have the unilateral right, upon
written notice provided pursuant to Paragraph 10, to accelerate the payment of
the aggregate amount of future cash compensation which would be payable to Mr.
Wolfe pursuant to Paragraphs 3 and/or 6 hereof. Within sixty days following
receipt of written notice from Mr. Wolfe, Keystone shall pay the balance of the
future cash compensation due Mr. Wolfe under this Agreement in a single lump
sum. Payment of such sum shall release and relieve Keystone from all further
obligations hereunder, including the obligation to pay or make available to Mr.
Wolfe any employee benefits other than as may be required by law.
Notwithstanding such accelerated payment, Mr. Wolfe expressly agrees to honor
and abide by the provisions of Paragraph 8 hereof, the violation of which may be
enforced by Keystone in a suit at law or in equity without regard to Paragraph
13.

   For purposes of thisParagraph, "Change of Control" means the occurrence of
any one of the following events:

         (a) Keystone acquires actual knowledge that any Person (other than
Keystone, any subsidiary of Keystone, any employee benefit plan of Keystone or
any its subsidiaries or any entity holding securities for or pursuant to the
terms of any such plan) has acquired the Beneficial Ownership, directly or
indirectly, of securities of Keystone entitling such Person to a majority of the
voting power of Keystone's Voting Stock;

                                      -2-
<PAGE>
 
         (b)  A majority of the Board of Directors of Keystone ("Board") shall
consist of persons other than (i) persons who were members of the Board
immediately following the Effective Time, or (ii) persons (A) whose nomination
or election as directors of Keystone was approved by at least two-thirds of the
then members of the Board (excluding any director referred to in clause (B) of
this paragraph) who either were directors of Keystone on such date or whose
nomination or election as a director was so approved and (B) who are not
nominees or representatives of (1) any Person having Beneficial Ownership,
directly or indirectly, of securities of Keystone entitling such Person to 10%
or more of the voting power of Keystone's Voting Stock or (2) any
"participant," as defined in Rule 14a-11 under the Securities Exchange Act of
1934 (the "Exchange Act") or any successor rule, in any actual or threatened
solicitation (other than a solicitation by Keystone) subject to Rule 14a-11 or
any successor rule and relating to the election or removal of any directors of
Keystone; or

         (c) Keystone and/or any of its subsidiaries shall be a party to any
merger, consolidation, division, share exchange, transfer of assets or any
other transaction or series of related transactions outside the ordinary course
of business (a "Business Combination") as a result of which the shareholders of
Keystone immediately prior to such Business Combination (excluding any party,
other than Keystone or a subsidiary, to the Business Combination or any
Affiliate or Associate of any such party) shall not hold immediately following
such transaction a majority of the voting power of the Voting Stock of a Person
or Persons immediately thereafter holding, directly or indirectly through
subsidiaries, assets of Keystone and its consolidated subsidiaries immediately
prior to the Business Combination constituting at least 65% of Total Assets.

As used in this definition of "Change of Control," (1) the terms "Person,"
"Affiliate," "Associate," "Voting Stock" and "Total Assets" shall have the
definitions contained in, and "Beneficial Ownership" shall be determined as
provided in, Article 10 of Keystone's Restated Articles of Incorporation, as in
effect on the date hereof, and (2) the uncapitalized term "subsidiary," when
used with respect to a specified Person, shall mean any corporation of which
such Person owns, directly or indirectly through subsidiaries, a majority of
each class of equity security having ordinary voting power in an election of
directors.

Following a Change of Control defined in paragraph (3), the term "Keystone" as
used herein, shall mean the Person which following such Change of Control holds
the largest percentage of Keystone's Total Assets, including for this purpose
Total Assets which are held by such Person directly or indirectly through one or
more subsidiaries. Keystone shall not enter into any transaction involving such
a Change of Control, unless at or prior to the consummation thereof, such Person
assumes the obligations of Keystone hereunder.

    8. Non-Disclosure and Non-Competition. Mr. Wolfe recognizes and acknowledges
that during the course of his employment with Financial Trust Corp, and during
the course of his future employment with Keystone, he has acquired and/or may
subsequently acquire privileged and confidential information concerning
Financial Trust Corp's and/or Keystone's current and prospective customers,
their methods and ways of doing business, their plans and goals for future
activities and other confidential or proprietary information belonging to
Financial Trust Corp or Keystone or relating to Financial Trust Corp's or
Keystone's affairs (collectively referred to herein as the "Confidential
Information"). Mr. Wolfe further acknowledges and agrees that the Confidential
Information is the property of Keystone and that any misappropriation or
unauthorized use or disclosure of the Confidential Information would constitute
a breach of trust and could cause irreparable injury to Keystone, and that it is
essential to the protection of

                                      -3-
<PAGE>
 
Keystone and its good will, and to the maintenance of Keystone's competitive
position that the Confidential Information be kept secret and not be disclosed
to others or used to Mr. Wolfe's own advantage or the advantage of others.

     Accordingly, Mr. Wolfe agrees that:

         (a) Non-Disclosure of Confidential Information. During his employment
             ------------------------------------------
hereunder and thereafter Mr. Wolfe shall hold and safeguard the Confidential
Information in trust for Keystone, its successors and assigns; that he shall
not, without the prior written consent of Keystone, misappropriate or disclose
or make available to anyone for use outside Keystone at any time, either during
his employment or subsequent to the termination of his employment, any of the
Confidential Information, whether or not developed by Mr. Wolfe; and

         (b) Restrictions on Competition. Further, Mr. Wolfe agrees that he
             ---------------------------
shall not, either during his employment with Keystone or during the period
beginning on the date of his termination of employment and ending on the last
day of the 24th month thereafter, without first obtaining the written consent of
the Board of Directors of Keystone, directly or indirectly, as an officer,
director, employee, consultant, agent, partner, joint venturer, proprietor or
other, engage in, become interested in or assist any business which is in
competition with Keystone or any of its subsidiaries in the areas of commercial
banking, mortgage banking, leasing or the taking of deposits, and is located or
operating in any of the counties in which Keystone or any of its present or
future subsidiaries may now or at any time prior to the termination of Mr.
Wolfe's employment have offices, or any of the counties contiguous thereto,
other than as a shareholder holding not more than 1% of the outstanding shares
of any class of securities registered under the Securities Exchange Act of 1934.

Gentlemen:

     The undersigned director of First Financial Corporation of Western Maryland
(the "Company") understands that Keystone Financial, Inc. (the "Acquiror") is
about to enter into an Agreement and Plan of Merger (the "Merger Agreement")
with the Company. The Merger Agreement provides for the merger of the Company
with and into the Acquiror (the "Merger") and the conversion of outstanding
shares of Company Common Stock into Acquiror Common Stock or cash in accordance
with the terms therein set forth.

     In order to induce Keystone to enter into the Merger Agreement, and
intending to be legally bound hereby, the undersigned represents, warrants and
agrees that at the meeting of the Company's shareholders contemplated by Section
5.2 of the Merger Agreement and any adjournment thereof the undersigned will, in
person or by proxy, vote or cause to be voted in favor of the Merger Agreement
and the Merger the shares of Company Common Stock beneficially owned by the
undersigned individually or, to the extent of the undersigned's proportionate
voting interest, jointly with other persons, as well as (to the extent of the
undersigned's proportionate voting interest) any other shares of Company Common
Stock over which the undersigned may hereafter acquire beneficial ownership in
such capacities (collectively, the "Shares"). Subject to the final paragraph of
this agreement, the undersigned further agrees that he will use his best efforts
to cause any other shares of Company Common Stock over which he has or shares
voting power to be voted in favor of the Merger Agreement and the Merger.

     The undersigned further represents, warrants and agrees that until the
earlier of (i) the consummation of the Merger or (ii) the termination of the
Merger Agreement in accordance with its terms, the undersigned will not,
directly or indirectly:

         (a) vote any of the Shares, or cause or permit any of the Shares to be
     voted, in favor of any other merger, consolidation, plan of liquidation,
     sale of assets, reclassification or other transaction involving the Company
     or First Federal Savings Bank of Western Maryland (the "Bank") which would
     have the effect of any person, other than the Acquiror or an affiliate of
     the Acquiror, acquiring control over the Company, the Bank or any
     substantial portion of the assets of the Company or the Bank. As used
     herein, the term "control" means (1) the ability to direct the voting of
     10% or more of the outstanding voting securities of a person having
     ordinary voting power in the election of directors or in the election of
     any other body having similar functions or (2) the ability to direct the
<PAGE>
 
     management and policies of a person, whether through ownership of
     securities, through any contract, arrangement or understanding or
     otherwise.

         (b) sell or otherwise transfer any of the Shares, or cause or permit
     any of the Shares to be sold or otherwise transferred (i) pursuant to any
     tender offer, exchange offer or similar proposal made by any person other
     than the Acquiror or an affiliate of the Acquiror, (ii) to any person known
     by the undersigned to be seeking to obtain control of the Company, the Bank
     or any substantial portion of the assets of the Company or the Bank or to
     any other person (other than the Acquiror or an affiliate of the Acquiror)
     under circumstances where such sale or transfer may reasonably be expected
     to assist a person seeking to obtain such control or (iii) for the
     principal purpose of avoiding the obligations of the undersigned under this
     agreement.

     It is understood and agreed that this agreement relates solely to the
capacity of the undersigned as a shareholder or other beneficial owner of the
Shares and is not in any way intended to affect the exercise by the undersigned
of the undersigned's responsibilities as a director or officer of the Company or
the Bank. It is further understood and agreed that the term "Shares" shall not
include any securities beneficially owned by the undersigned as a trustee or
fiduciary, and that this agreement is not in any way intended to affect the
exercise by the undersigned of the undersigned's fiduciary responsibility in
respect of any such securities.

                                        Very truly yours
