                          Proxy Statement/Prospectus

                           KEYSTONE FINANCIAL, INC.
    
                 501,150 Shares of Common Stock, $2 par value
                       issuable in proposed merger with
     
                    SHAWNEE FINANCIAL SERVICES CORPORATION
    
        This Proxy Statement/Prospectus is being furnished to the shareholders
  of Shawnee Financial Services Corporation ("Shawnee") in connection with the
  solicitation of proxies by its Board of Directors for use at a Special Meeting
  of Shareholders of Shawnee to be held on August 1, 1995.  The purpose of the
  Special Meeting is to consider a proposed merger (the "Merger") of Shawnee
  into Keystone Financial, Inc. ("Keystone").  As a result of the Merger,
  Keystone, which will be the surviving corporation, will acquire all of the
  assets and liabilities of Shawnee, and the shareholders of Shawnee will become
  shareholders of Keystone.  Each outstanding share of Shawnee Common Stock will
  be converted in the Merger into 6.25 shares of Keystone Common Stock.  The
  Keystone Common Stock is quoted on the NASDAQ National Market System under the
  symbol "KSTN."  Based on the June 20, 1995 closing sale price for Keystone
  Common Stock of $28.125 per share, the value of the 6.25 shares of Keystone
  Common Stock being offered for each Shawnee share in the Merger would be
  $175.78.  Shawnee shareholders should note that the market value of the
  Keystone Common Stock may change prior to consummation of the Merger.  The
  approximate date on which this Proxy/Statement Prospectus will first be mailed
  to the shareholders of Shawnee is June      , 1995.

                                    SUMMARY


        The following is a brief summary of certain information which may also
  be contained elsewhere in this Proxy Statement/Prospectus. This summary is
  provided for convenience and should not be considered complete.  It is
  qualified in its entirety by the more detailed information contained in this
  Proxy Statement/Prospectus and in the Annexes hereto.


  The Parties
    
        Keystone Financial, Inc. ("Keystone") is a bank holding company with its
  principal executive offices at One Keystone Plaza, Front and Market Streets,
  P.O. Box 3660, Harrisburg, Pennsylvania  17105-3660 (telephone:  717-233-
  1555).

        In terms of assets, Keystone is the seventh largest bank holding company
  in Pennsylvania.  Its banking subsidiaries are Mid-State Bank and Trust
  Company, Altoona, Pennsylvania ("Mid-State"); Pennsylvania National Bank and
  Trust Company, Pottsville, Pennsylvania; Northern Central Bank, Williamsport,

  Bank, Cumberland, Maryland; and American Trust Bank of West Virginia, Inc.,

        Keystone's subsidiary banks provide a wide range of financial products
  and services through a combined total of 140 community offices located in
  central and southeastern Pennsylvania, western Maryland and northeastern West
  Virginia.  Keystone's subsidiary banks operate under the "supercommunity"
  banking philosophy, functioning as local community banks with a personalized
  service approach to customers while at the same time taking advantage of the
  size of the larger Keystone organization to provide a broad product line and
  gain operating and management efficiencies through economies of scale.  In
  addition to the traditional banking services provided by its member banks,
  Keystone has established several nonbanking subsidiaries to deliver an array
  of services to both Keystone and its customers, including brokerage, mortgage
  banking, leasing, investments and credit life and accident and health
  insurance.  See "Keystone Documents Incorporated by Reference."

        Keystone Common Stock is traded in the over-the-counter market under the
  symbol "KSTN" and is listed in the NASDAQ National Market System.  On June 20,
  1995, the closing sale price for Keystone Common Stock on the NASDAQ National
  Market System was $28.125.  See "Information Concerning Keystone--Stock Prices
  and Dividends on Keystone Common Stock."

        At March 31, 1995, Keystone reported consolidated total assets of $4.680
  billion, deposits of $3.825 billion and net loans and leases of $3.195
  billion.  Keystone reported net income of $51,359,000, or $2.20 per share, for
  the year ended December 31, 1994 and net income of $14,656,000, or $0.63 per
  share, for the three months ended March 31, 1995.  See "Information Concerning
  Keystone--Selected Financial Data" and "Keystone Documents Incorporated by
  Reference."

        Shawnee Financial Services Corporation ("Shawnee") is a bank holding
  company with its principal executive offices at 115 East Main Street, Everett,
  Pennsylvania 15537 (telephone:  814-652-5138).  Its sole subsidiary is The
  Everett Bank, which has four banking offices in Bedford County in central
  Pennsylvania.  See "Information Concerning Shawnee--Business of Shawnee."

        At March 31, 1995, Shawnee reported consolidated total assets of $71.209
  million, deposits of $62.627 million and net loans of $38.752 million.
  Shawnee reported net income of $727,000, or $9.07 per share, for the year
  ended December 31, 1994 and net income of $191,000, or $2.38 per share, for
  the three months ended March 31, 1995.  See "Information Concerning Shawnee--

  The Shawnee Special Meeting
    
        The Special Meeting of Shareholders of Shawnee (the "Special Meeting")
  will be held at 11:00 a.m., local time, on August 1, 1995 at The Everett
  Bank's Board Room, 115 East Main Street, Everett, Pennsylvania.  Only holders
  of record of Common Stock, par value $10.00 per share, of Shawnee ("Shawnee
  Common Stock") at the close of business on June 24, 1995 will be entitled to
  vote at the Special Meeting.  At that date, 80,184 shares of Shawnee Common
  Stock were outstanding, each share being entitled to one vote.  See
  "Introduction."
     
  The Merger
    
        At their Special Meeting, the shareholders of Shawnee will be asked to
  approve an Agreement and Plan of Reorganization and a related Agreement and
  Plan of Merger (collectively, the "Plan of Merger") between Keystone and
  Shawnee.  The Plan of Merger provides for the merger of Shawnee into Keystone
  (the "Merger").  It is contemplated that simultaneously with or following the
  Merger, The Everett Bank will be merged (the "Bank Merger") into Mid-State,
  one of Keystone's operating bank subsidiaries.  See "Plan of Merger--The
  Merger."  As a result of the Merger, each outstanding share of Shawnee Common
  Stock will be converted into 6.25 shares of Keystone Common Stock, with cash
  to be paid in lieu of any fractional share.  See "Plan of Merger--Conversion
  of Shawnee Shares."  On June 20, 1995, the closing sale price for Keystone
  Common Stock on the NASDAQ National Market System was $28.125 per share.
     

  Reasons for the Merger

        Shawnee.  The past several years have evidenced significant changes in
  the banking industry, including greater regulation at the federal level (both
  in terms of paperwork and complexity) and significant consolidation among
  banks.
    
        During the first quarter of 1994, the Board of Directors of Shawnee
  began to consider its goals for the future.  These goals included the
  enhancement of shareholder value, continued service to the Everett area and
  surrounding communities and continued attention to the needs of its employees.
  In April 1994, certain representatives of Shawnee were approached by Keystone
  concerning a possible merger of the two companies.  Throughout the summer and
  fall of 1994, these discussions continued, leading to a definitive proposal in
  November 1994 for Keystone to acquire Shawnee.  This proposal addressed issues
  relating to the structure of the transaction as a tax-free exchange, and
  proposed an exchange ratio of 5.849 shares of Keystone Common Stock for each
  share of Shawnee Common Stock outstanding.

        Berwind Financial Group, L.P. ("Berwind") was retained by the Board in
  October 1994 to advise it concerning the financial aspects of a potential
  merger with Keystone or another party.  Berwind has represented many banks in
  acquisition transactions, acting on behalf of both acquirors and acquirees.
  Berwind reported its preliminary findings on the value of Shawnee to the Board
  of Directors in December 1994.  Following this presentation, the Board
  directed Berwind to negotiate with Keystone over the next week to obtain a
  higher price for Shawnee shareholders while meeting the Board's other, non-
  financial objectives.  Berwind reported back to the Board on December 13, 1994
  that Keystone would be willing to increase its offer to 6.25 shares of
  Keystone Common Stock for each share of Shawnee Common Stock outstanding,
  which the Board then voted to accept.  The Board directed its attorneys to
  proceed to negotiate a definitive merger agreement with Keystone.  This
  agreement was negotiated between the parties, presented to the Board, and
  signed on January 5, 1995.

        Prior to the signing of the Plan of Merger with Keystone, Shawnee
  received an opinion from its financial advisor to the effect that the Keystone
  offer was fair to the shareholders of Shawnee.  Details of this opinion and
  Berwind's analysis are set forth in greater detail in this Proxy
  Statement/Prospectus.  See "Plan of Merger--Opinion of Shawnee Financial
  Advisor."  In addition to Berwind's fairness opinion, the Board favored the
  Merger for various other reasons, including the strength of Keystone as a
  banking institution and its ability to continue to serve customers in the
  bank's market, opportunities for The Everett Bank's employees within
  Keystone's organization
     

                                     -iv-

  and the significant benefits to Shawnee shareholders resulting from the
  consideration offered by Keystone and the tax-free nature of the transaction.
  For a more complete discussion of these reasons, see "Plan of Merger--
  Background of and Reasons for the Merger."

        Based upon the above and other factors, the Board unanimously approved
  the Plan of Merger on January 5, 1995.
    
          Shawnee has been contacted periodically by other banking institutions
  which have expressed an interest in a possible merger.  Since beginning its
  discussions with Keystone last year, three bank holding companies have
  indicated orally a preliminary interest, and one bank holding company has
  expressed such an interest by means of a letter.  No oral or written offer was
  made by any of such parties, and Shawnee did not pursue any further contact
  with these parties.
     
        Keystone.  For Keystone, the addition of Everett's offices to Mid-State
  resulting from the Merger and the Bank Merger will provide a natural extension
  to Mid-State's market area and a bridge between the areas served by Mid-State
  and American Trust Bank, Keystone's subsidiary headquartered in Cumberland,
  Maryland.  The Merger will enable Mid-State to better serve the agricultural
  market in eastern Bedford County and to serve this market's larger commercial
  customers by providing financial products and services which Everett has been
  unable to provide.


  Vote Required for Approval
    
        Approval of the Plan of Merger by the shareholders of Shawnee requires
  the affirmative vote of the holders of at least 75% of the outstanding shares
  of Shawnee Common Stock.  A failure to vote, an abstention or a broker non-
  vote will have the same legal effect as a vote against the approval of the
  Plan of Merger.  See "Plan of Merger--Required Vote; Management
  Recommendation."  As of June 19, 1995, the directors and executive officers of
  Shawnee beneficially owned an aggregate of 21.33% of the outstanding Shawnee
  Common Stock.

        The directors and executive officers of Shawnee have entered into
  agreements with Keystone to vote in favor of the Merger shares of Shawnee
  Common Stock beneficially owned by them individually or jointly and to use
  their best efforts to cause certain other shares over which they have or share
  voting power to be voted in favor of the Merger.  These agreements cover an
  aggregate of 21.33% of the outstanding Shawnee Common Stock.  No monetary or
  other compensation was paid to any Shawnee director or executive officer for
  entering into these agreements.  See "Plan of Merger--Voting Agreements."

        The Trust Department of Keystone's wholly owned subsidiary, Mid-State,
  acting in a fiduciary capacity, has voting power over 8.37% of the outstanding
  Shawnee Common Stock.  It is anticipated that these shares will be voted in
  favor of the Merger.
     
        The Merger does not require approval by the shareholders of Keystone.


  Opinion of Financial Advisor
    
        The investment banking firm of Berwind Financial Group, L.P.  has
  rendered an opinion to Shawnee dated June      , 1995 that the terms of the
                                            -----
  Merger are fair, from a financial point of view, to Shawnee and its
  shareholders.  This opinion is attached as Annex I to this Proxy
  Statement/Prospectus and should be read in its entirety for information as to
  the matters considered and the assumptions made in rendering such opinion.
  See "Plan of Merger--Opinion of Shawnee Financial Advisor."

  Board of Directors' Recommendation

        The Board of Directors of Shawnee believes that the Merger is in the
  best interests of the shareholders of Shawnee and unanimously recommends that
  Shawnee shareholders vote "FOR" approval of the Plan of Merger.

        SHAWNEE SHAREHOLDERS ARE REQUESTED TO COMPLETE, DATE AND SIGN THE
  ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY IN THE ENCLOSED POSTAGE-PAID
  ENVELOPE.


  Post-Merger Boards of Directors

        Following the Bank Merger, L. Frank Bittner, presently Chairman of the
  Board of Directors of Shawnee, will become a member of the Board of Directors
  of Mid-State.  No change in the Board of Directors of Keystone will be made by
  reason of the Merger.  See "Plan of Merger--Boards of Directors Following the
  Merger."


  Interests of Certain Persons in the Transaction
    
        As a director of Mid-State, L. Frank Bittner will receive the same fees
  as other Mid-State directors, consisting of an annual retainer of $3,500, plus
  $500 per Board meeting and $200 per Board Committee meeting attended.  Samuel
  K. Bohn, the President and a director of Shawnee and Everett, will be offered
  $50,000 per year for a two-year period to assist in the post-Merger transition
  and/or for a covenant not to compete.  Ralphard L. Black, Vice President of
  Shawnee and Executive Vice President of Everett, will be employed as a Vice
  President of Mid-State without change by reason of the Merger in his salary,
  which is currently $65,000 per year.

        It is not intended that any of the remaining directors and executive
  officers of Shawnee, none of whom are employees, will be retained by Keystone
  or Mid-State following the Merger.  No severance or similar payments will be
  made to such persons.
     
        Keystone has agreed to indemnify Shawnee's directors and officers with
  respect to events occurring prior to the Merger and to provide such persons
  with certain directors' and officers' liability insurance coverage.  See "Plan
  of Merger--Interests of Certain Persons in the Transaction."

    
  Employee Matters

        Keystone has agreed to consider Everett employees for employment within
  the Keystone organization to permit Everett employees employed by Keystone and
  its subsidiaries to participate on an equal basis in Keystone's internal open
  position posting and application procedures.  Shawnee and Everett employees
  who become employees of Keystone and its subsidiaries will be provided
  employee benefits no less favorable than those provided to other similarly
  situated employees.  Following the Merger, Keystone and Mid-State will perform
  the respective obligations of Shawnee and Everett with respect to vested
  benefits accrued under Everett's retirement and profit sharing plans.
     

  Tax Consequences

        No gain or loss for federal or Pennsylvania income tax purposes will be
  recognized by shareholders of Shawnee on the exchange of their shares for
  Keystone Common Stock in the Merger, except with respect to cash received in
  lieu of fractional shares and cash paid to shareholders who elect dissenters'
  rights.  For a more complete



                                     -vi-

<PAGE>
 
  description of the Federal and Pennsylvania income tax consequences of the
  Merger, see "Plan of Merger--Tax Consequences to Shawnee Shareholders."


  Warrant Agreement

        In connection with the Plan of Merger, Shawnee has entered into an
  agreement granting Keystone a warrant to purchase up to 19.9% of the
  outstanding Shawnee Common Stock, at an exercise price of $182.81 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 Shawnee.  The Warrant Agreement is designed to
  compensate Keystone for its risks, costs and expenses and the commitment of
  resources associated with the Plan of Merger in the event the Merger is not
  consummated due to an attempt by a third person to gain control of Shawnee.
  The Warrant Agreement may discourage third persons from making competing
  offers to acquire Shawnee and is intended to increase the likelihood that the
  Plan of Merger will be consummated in accordance with its terms.  Exercise of
  the warrant for more than 5% of the outstanding Shawnee Common Stock would be
  subject to the approval of regulatory authorities.  See "Plan of Merger--
  Warrant Agreement."


  Dissenters' Rights

        Record holders of Shawnee Common Stock who object to the Merger and
  comply with the prescribed statutory procedures are entitled to have the fair
  value of their shares determined in accordance with the Pennsylvania Business
  Corporation Law and paid to them in cash in lieu of the shares of Keystone
  Common Stock they would otherwise be entitled to receive in the Merger.  A
  copy of the pertinent statutory provisions is attached to this Proxy
  Statement/Prospectus as Annex II.  Failure to follow such provisions precisely
  may result in a loss of dissenters' rights.  See "Plan of Merger--Dissenters'
  Rights of Shawnee Shareholders."

    
  Differences in Shareholder Rights

        The rights of the holders of Keystone Common Stock differ in certain
  respects from those of the holders of Shawnee Common Stock.  While for both
  Shawnee and Keystone certain mergers and other potential change-of-control
  transactions and certain amendments to the articles of incorporation or by-
  laws require approval by 75% of the outstanding shares, the types of
  transactions or amendments subject to the special vote requirements differ
  between the two companies, and a such transaction or amendment involving
  Keystone would also require approval by a majority of the shares not
  beneficially owned by a 20% shareholder.  While both Keystone and Shawnee 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
  Shawnee, Keystone has established a shareholder rights plan and is subject to
  certain provisions of the Pennsylvania Business Corporation Law which may
  discourage outside persons from attempting to acquire control of Keystone or
  make such an attempt more difficult.  Because Keystone Common Stock is
  publicly traded, holders of Keystone Common Stock are not entitled to
  dissenters' appraisal rights in a variety of situations in which such rights
  would be available to shareholders of Shawnee.  Unlike Shawnee, 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 Shawnee
  Common Stock and those of the holders of Keystone Common Stock, see
  "Comparison of Keystone Common Stock and Shawnee Common Stock."
     

  Regulatory Approvals

        The Merger requires approval by the Board of Governors of the Federal
  Reserve System and the Pennsylvania Department of Banking.  The Bank Merger
  requires approval by the FDIC and the Pennsylvania



                                     -vii-

<PAGE>
 
     
  Department of Banking.  Applications for these approvals have been 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 the
  Merger is contingent upon the receipt of certain tax opinions and the
  satisfaction of a number of other conditions.  See "Plan of Merger--Conditions
  to the Merger."  Notwithstanding prior shareholder approval, the Plan of
  Merger may be amended in any respect other than the ratio for converting
  Shawnee Common Stock into Keystone Common Stock in the Merger.

        The Plan of Merger may be terminated, and the Merger abandoned,
  notwithstanding prior shareholder approval, by mutual agreement of Keystone
  and Shawnee or by either of them in the event of a material breach by the
  other party, failure to receive shareholder or regulatory approval or failure
  to satisfy the conditions to the Merger prior to September 30, 1995 or, in
  certain circumstances, December 31, 1995.  Shawnee may also terminate the Plan
  of Merger if (1) the average closing bid price for Keystone Common Stock for
  the 10 trading days ending six trading days prior to the closing date for the
  Merger is less than $24.86 and (2) such decline in Keystone's stock price
  exceeds by more than 15% the decline in the NASDAQ Combined Bank Index since
  January 4, 1995.   See "Plan of Merger--Amendment, Waiver and Termination."


  Effective Date of the Merger
    
        It is presently anticipated that if the Plan of Merger is approved by
  the shareholders of Shawnee, the Merger will become effective in the third
  quarter of 1995.  However, there can be no assurance that all conditions
  necessary to the consummation of the Merger will be satisfied or, if
  satisfied, that they will be satisfied in time to permit the Merger to become
  effective at the anticipated time.  See "Plan of Merger--Effective Date of the
  Merger."
     
 
  Exchange of Certificates

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

  Pre-Announcement Prices
    
        The following table sets forth (i) the closing sale price for Keystone
  Common Stock on the NASDAQ National Market System on January 5, 1995, the last
  trading day prior to the first public announcement of the Merger and (ii) an
  equivalent per share price for Shawnee Common Stock computed by multiplying
  the closing sale price for Keystone Common Stock on January 5, 1995 by the
  Merger exchange ratio of 6.25 to 1.

  Shawnee Common Stock........         --               $185.16
</TABLE>
  
        On June 20, 1995, the closing sale price for Keystone Common Stock was
  $28.125.  Using this price, the equivalent per share price for Shawnee Common
  Stock would have been $175.78.

        The last trade of Shawnee Common Stock known to Shawnee management to
  have occurred prior to announcement of the Merger was a trade of 300 shares of
  Shawnee Common Stock at $92.00 per share on January 4, 1995 by parties not
  affiliated with Shawnee.  There is no established market for Shawnee Common
  Stock, and there has been only limited trading in Shawnee Common Stock.
  Therefore, this price may not necessarily be indicative of the true market
  value of Shawnee Common Stock.


  Accounting Treatment

        Normally, the Merger would be accounted for by Keystone under the
  pooling-of-interests method of accounting.  However, if the number of treasury
  shares purchased by Keystone under its share repurchase program exceeds
  certain limits, Keystone may be required to account for the Merger under the
  purchase method of accounting.  See "Plan of Merger--Accounting Treatment."

        Pro forma financial information concerning the Merger is not included
  herein since the addition of Shawnee under either accounting method would not
  have materially affected the Keystone historical financial information as
  presented.

                                 INTRODUCTION
    
        This Proxy Statement/Prospectus is furnished in connection with the
  solicitation by the Board of Directors of Shawnee Financial Services
  Corporation ("Shawnee") of proxies to be voted at a Special Meeting of
  Shareholders of Shawnee (the "Special Meeting") to be held on Tuesday, August
  1, 1995 and at any adjournment or adjournments thereof.  The Special Meeting
  will be held at 11:00 a.m., local time, at the Board Room of The Everett Bank,
  115 East Main Street, Everett, Pennsylvania.  The approximate date on which
  this Proxy Statement/Prospectus will first be mailed to the shareholders of
  Shawnee is June      , 1995.
                  -----
     
  Record Date; Voting Rights
    
        The Board of Directors of Shawnee has fixed the close of business on
  June 24, 1995 as the record date for determining the shareholders of Shawnee
  entitled to notice of and to vote at the Special Meeting.  At that date,
  80,184 shares of Common Stock, par value $10.00 per share, of Shawnee
  ("Shawnee Common Stock") were outstanding.  Each such share entitles its
  holder of record at the close of business on the record date to one vote on
  each matter properly submitted to the shareholders for action at the Special
  Meeting.  Shawnee does not have any other outstanding class of capital stock.
  On June 19, 1995, there were approximately 168 shareholders of record of
  Shawnee Common Stock.
     

  Purpose of the Special Meeting

        At the Special Meeting, the shareholders of Shawnee 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
  January 5, 1995 (collectively, the "Plan of Merger"), between Shawnee and
  Keystone Financial, Inc. ("Keystone").  As more fully described below under
  "Plan of Merger," the Plan of Merger provides for a merger of Shawnee into
  Keystone (the "Merger").  In the Merger, each outstanding share of Shawnee
  Common Stock (other than shares subject to dissenters' rights) will be
  converted into 6.25 shares of Keystone Common Stock.  It is contemplated that
  simultaneously with or shortly following the Merger, Shawnee's subsidiary, The
  Everett Bank ("Everett"), will be merged into Mid-State Bank and Trust Company
  ("Mid-State"), one of Keystone's operating bank subsidiaries.
    
        Shawnee has received an opinion of the investment banking firm of
  Berwind Financial Group, L.P. that the terms of the Merger are fair to the
  shareholders of Shawnee from a financial point of view.  See "Plan of Merger--
  Opinion of Shawnee Financial Advisor."
     
        THE BOARD OF DIRECTORS OF SHAWNEE BELIEVES THAT THE MERGER IS IN THE
  BEST INTERESTS OF THE SHAREHOLDERS OF SHAWNEE AND UNANIMOUSLY RECOMMENDS THAT
  SHAWNEE SHAREHOLDERS VOTE TO APPROVE THE PLAN OF MERGER.
<PAGE>
 
  Voting and Revocation of Proxies
    
        All properly executed proxies not theretofore revoked will be voted at
  the Special Meeting or any adjournments thereof in accordance with the
  instructions thereon.  Proxies containing no voting instructions will be voted
  in favor of approval of the Plan of Merger.  As to any other matter brought
  before the Special Meeting and submitted to a shareholder vote, proxies will
  be voted in accordance with the judgment of the proxyholders named thereon.
  However, the proxy of any shareholder who votes against approval of the Plan
  of Merger will not be used to vote in favor of any proposal to adjourn the
  Special Meeting in the event Shawnee management wishes to adjourn the meeting
  in order to allow time for the solicitation of additional votes to approve the
  transaction.
     
        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 Shawnee written notice
  of such revocation or a later dated proxy or by attending the Special Meeting
  and voting in person.  Attendance at the Special Meeting will not, of itself,
  constitute a revocation of a proxy.


  Solicitation of Proxies
    
        In addition to solicitation by mail, directors, officers and employees
  of Shawnee may solicit proxies from the shareholders of Shawnee in person or
  by telephone or otherwise.  No additional compensation will be paid for such
  solicitation.  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.  Shawnee will bear its own expenses in connection with the
  solicitation of proxies for the Special Meeting, except that Keystone and
  Shawnee will each pay 50% of the printing costs related to the solicitation of
  proxies from Shawnee shareholders.  See "Plan of Merger--Expenses."  Shawnee
  estimates that its out-of-pocket expenses in connection with the solicitation
  of proxies for the Special Meeting will be approximately $5,500, including 50%
  of total printing costs estimated at $9,000.
     

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

  The Merger
    
        The Plan of Merger provides for a merger of Keystone and Shawnee in
  which Keystone will be the surviving corporation.  As a result of the Merger,
  Keystone will acquire all of the assets and liabilities of Shawnee, and
  Shawnee will cease to exist as a separate corporation.
     
        In the Merger, the shareholders of Shawnee will become shareholders of
  Keystone.  Each of the approximately 80,184 outstanding shares of Shawnee
  Common Stock (other than shares subject to dissenters' rights) will be
  converted into 6.25 shares of Keystone Common Stock, with cash to be paid in
  lieu of any fractional share.  See "Conversion of Shawnee Shares."
    
        Keystone is a bank holding company with its principal executive offices
  in Harrisburg, Pennsylvania.  The principal subsidiaries of Keystone are Mid-
  State, Altoona, Pennsylvania; Pennsylvania National Bank and Trust Company,
  Pottsville, Pennsylvania; Northern Central Bank, Williamsport, Pennsylvania;
  The Frankford Bank, N.A., Horsham, Pennsylvania; American Trust Bank,
  Cumberland, Maryland; and American Trust Bank of West

  Virginia, Inc., Keyser, West Virginia.  Keystone's bank subsidiaries operate a
  combined total of 140 banking offices in central and southeastern
  Pennsylvania, western Maryland and northeastern West Virginia.  See "Summary--
  The Parties--Keystone" and "Keystone Documents Incorporated by Reference."

        Shawnee is a bank holding company with its principal executive offices
  in Everett, Pennsylvania.  Shawnee's sole subsidiary is Everett, which has
  four banking offices in Bedford County in central Pennsylvania.  See "Business
  of Shawnee."  It is contemplated that simultaneously with or shortly following
  the Merger of Shawnee and Keystone, Everett will be merged into Mid-State.
     

  Background of and Reasons for the Merger

        Shawnee.  In the view of Shawnee's management, the past several years
  have been a period of substantial and rapid change in the banking industry in
  general.  Recent changes in federal and state banking laws and regulations
  have had a major impact upon the banking industry in Pennsylvania and
  throughout the United States.  In response to these changes, many mergers and
  consolidations involving banks and bank holding companies have occurred.
  Further merger activity is likely to occur in the future, resulting in
  increased concentration levels in banking markets and other significant
  changes in the competitive environment.  These changes are expected to
  intensify competition in local and regional banking markets. In addition,
  recent changes in banking laws have significantly increased the severity and
  complexity of banking regulations, as well as increasing the costs that banks
  must incur in complying with those regulations.  With these considerations in
  mind, the Board of Directors began to consider its future course of action in
  early 1994.

        During the spring of 1994, representatives of Keystone approached
  Shawnee's senior management to indicate Keystone's interest in pursuing a
  possible acquisition of Shawnee.  A series of initial contacts and preliminary
  discussions ensued over the next few months, and in June of 1994 Keystone made
  a preliminary overture to acquire Shawnee.  Although no definitive decision
  had been made by the Board to sell the company at that time, Shawnee's Board
  decided it would be appropriate to retain legal and financial advisors to
  assist it in the evaluation of the Keystone proposal and other strategic
  options.
    
        In mid-October 1994, Shawnee retained the investment banking firm of
  Berwind Financial Group, L.P. ("Berwind"), to act as its financial advisor in
  connection with any possible transaction with Keystone.  Berwind has extensive
  experience in representing buyers and sellers in commercial transactions, with
  a particular expertise in the banking industry.  Berwind evaluated the
  business and prospects of Shawnee over the next several months, engaged in
  discussions with senior management about the same, and prepared an analysis of
  Shawnee to be presented to the Board.  In addition, upon the receipt of a more
  definitive offer from Keystone in November 1994, Berwind also prepared a
  preliminary analysis of this offer.

        The Keystone offer made on November 22, 1994 proposed a tax-free
  exchange of shares whereby 5.849 shares of Keystone stock would be tendered
  for each one share of Shawnee stock outstanding.  It also stated Keystone's
  intention to attempt to provide employment opportunity to as many of the
  bank's employees as possible, consistent with the previous discussions between
  the parties.  At Keystone's closing stock price on November 22, 1994, the
  aggregate value of the consideration offered to Shawnee's shareholders was
  $13,835,388.
     
        At a meeting of the Shawnee Board of Directors held on December 8, 1994,
  Shawnee's senior management provided its Board of Directors with reports on
  the status of the discussions with Keystone, including a discussion of the
  November 22 proposal.  Also, Berwind made detailed presentations regarding the
  financial consequences of Shawnee remaining as an independent financial
  institution or affiliating with a larger bank holding company, such as
  Keystone.  Substantial information was provided to the Shawnee Board of
  Directors regarding the likely future value of Shawnee's common stock under
  these different scenarios.
   
        In addition, evaluating only publicly available information, Berwind
  discussed with the Shawnee Board the financial condition and operations of
  Keystone and, in general, other large bank holding companies that might have
    
                                      -3-
<PAGE>
 
     
  an interest in making an acquisition in Shawnee's market, and the terms of
  other recent, comparable transactions.  The Board did not want to contact
  other potential acquirors prior to fully exploring a transaction with
  Keystone.  At the conclusion of the December 8th meeting, the Shawnee Board of
  Directors authorized Berwind to negotiate on its behalf with a view towards
  obtaining a higher price per share than that presented in the November 22
  proposal (5.849 shares of Keystone) while maintaining the Board's interest in
  protecting its employees and other constituencies.

        At the December 13, 1994 Board meeting, Berwind communicated to the
  Board of Directors that it was able to achieve an increase in the
  consideration offered per share from 5.849 shares of Keystone for each share
  of Shawnee to 6.25 shares of Keystone for each share of Shawnee common stock.
  Keystone's increased offer was conditioned upon Shawnee's agreeing to begin
  the negotiation of a definitive merger agreement.  Berwind advised that this
  offer was also subject to Keystone's performing a due diligence review on
  Shawnee and Shawnee engaging in a similar due diligence review of Keystone.
  Due diligence refers to the process where legal and financial representatives
  from each party review the books and records of the other party. Thereafter,
  the Board authorized its attorneys to negotiate with Keystone with a view
  toward reaching a definitive merger agreement that would address the legal,
  financial and social concerns of the Board.

        Over the next few weeks, representatives of Keystone and Shawnee
  conducted due diligence investigations of each others' respective operations
  and negotiated the Plan of Merger.  Keystone also informed Shawnee that, as a
  condition to Keystone's executing the Plan of Merger, Keystone would require
  the execution by Shawnee of the Warrant Agreement, thereby giving Keystone the
  ability to protect the benefit of its bargain in the event another acquiror
  would pay a higher price for Shawnee and the Board of Shawnee would accept
  such an offer.  The Warrant Agreement permits Keystone, under certain
  circumstances, to acquire up to 19.9% of the shares of Shawnee at a price of
  $182.81 per share (see "Plan of Merger--Warrant Agreement").

        Shawnee has been contacted periodically by other banking institutions
  which have expressed an interest in a possible merger.  Since beginning its
  discussions with Keystone last year, three bank holding companies have
  indicated orally a preliminary interest, and one bank holding company has
  expressed such an interest by means of a letter.  Only one of these bank
  holding companies was larger in asset size than Keystone.  No oral or written
  offer was made by any of such parties, and Shawnee did not pursue any further
  contact with these parties.
     
        On January 5, 1995, the Shawnee Board of Directors met to consider
  Keystone's acquisition proposal, including the Plan of Merger and the Warrant
  Agreement.  Attorneys from the law firm of Buchanan Ingersoll discussed with
  the Board of Directors the legal ramifications of the provisions of the merger
  agreements.  Berwind made a detailed presentation regarding the proposal and
  the alternatives available to Shawnee, and compared the terms of the Keystone
  proposal to the terms of other comparable transactions.  After the
  presentations, the financial advisor gave the opinion that, from a financial
  point of view, the offer from Keystone was fair to Shawnee and its
  shareholders.  At Keystone's closing stock price on January 5, 1995, the
  aggregate value of the consideration offered to Shawnee's shareholders was
  $14,846,569.  For a detailed discussion of the analysis underlying the
  financial advisor's fairness opinion, see "Plan of Merger--Opinion of Shawnee
  Financial Advisor."  Then, after extensive discussion and consideration, the
  Board of Directors unanimously voted to accept the Keystone proposal and
  approve the Plan of Merger and the Warrant Agreement.

        In reaching its determination to approve the Plan of Merger and the
  Warrant Agreement, the Shawnee Board of Directors considered a variety of
  factors, including:
    
  (1) The consideration offered by Keystone in the Plan of Merger in relation to
      the market value, book value and earnings per share of Shawnee on an
      historical basis;

  (2) Shawnee's business, results of operations, financial position and
      prospects for its remaining independent in a rapidly consolidating
      industry;
     
                                      -4-
<PAGE>
 
     
  (3) The management, business, results of operations and financial condition of
      Keystone, which the Board believes will serve the interests of its
      shareholders, its employees and the community served by Shawnee after the
      Merger;

  (4) The current and historical dividends paid on Shawnee Common Stock and
      Keystone Common Stock and the significant increase in dividends per year
      which would result to Shawnee's shareholders from the Merger;

  (5) The expectation that the Merger will be a tax-free transaction to Shawnee
      shareholders;

  (6) The financial terms of other recent business combinations in the banking
      industry;

  (7) The financial advice rendered by Berwind, including its opinion to the
      effect that the exchange ratio contemplated by the Plan of Merger is fair
      from a financial point of view to Shawnee shareholders;

  (8) The overall terms of the Plan of Merger, which provided protections for
      the employees of Shawnee;

  (9) The overall business environment in the banking industry, including
      increased competition from larger banks which offer a more diversified
      portfolio of products and services and the costs of complying with
      increasingly complex federal and state banking regulation; and

  (10) The benefit to shareholders of Shawnee by providing them with equity
       ownership in a larger, publicly traded banking organization and, thereby,
       increasing the liquidity of their investment.

        The Board considered factors (1), (4), (5) and (6) of great importance
  as a means to enhance its shareholders' value over the short, intermediate,
  and long-term.  The Board also believed that factors (3) and (8) were very
  significant because it hoped that the bank would be able to provide employment
  and serve its community into the future.  Other than the presentation made by
  Berwind, which provided certain quantifications with respect to recent,
  comparable transactions, the Board did not independently quantify, or assign
  weightings to any of the 10 reasons listed above.  Further, no negative
  factors were expressed by the Board with respect to the transaction with
  Keystone.
     
        The Board of Directors of Shawnee believes that the terms of the
  proposed Merger are fair to and in the best interests of Shawnee and its
  shareholders.  Shawnee's Board of Directors also believes that the Merger will
  significantly enhance the ability of Shawnee's offices to satisfy the
  financial needs of its present customers and the communities served.  For
  these reasons, the Board of Directors unanimously recommends that Shawnee
  shareholders vote to approve the merger of Shawnee into Keystone.

        Keystone.  For Keystone, the Merger is part of a continuing search for
  areas in which to expand its existing franchise.  The central part of
  Pennsylvania is historically Keystone's primary market area.  Keystone views
  this area as an attractive market and one with which it is familiar.  The
  territory served by Everett provides a bridge between the market areas of Mid-
  State and American Trust Bank, Keystone's subsidiary headquartered in
  Cumberland, Maryland.  Keystone views the addition of Everett's offices to
  Mid-State as a natural extension of Mid-State's market which provides Mid-
  State a means of better serving the agricultural market in eastern Bedford
  County.  Keystone also believes Mid-State can better serve this market's
  larger commercial customers through the acquisition of Everett because it can
  provide these customers with financial products and services which Everett has
  been unable to provide.  Finally, Keystone believes the expansion of its
  market by means of the Merger will result in increased efficiency and cost
  savings in the delivery of financial services.

  Required Vote; Management Recommendation

        Approval of the Plan of Merger requires the affirmative votes of the
  holders of at least 75% of the outstanding shares of Shawnee Common Stock,
  voting in person or by proxy at the Shawnee Special Meeting.  Because Shawnee
  shareholder approval requires the affirmative votes of 75% of all outstanding
  Shawnee shares, a failure to vote, an abstention or a broker non-vote will
  have the same legal effect as a vote by a Shawnee shareholder against approval
  of the Plan of Merger.  THE BOARD OF DIRECTORS OF SHAWNEE UNANIMOUSLY
  RECOMMENDS THAT SHAWNEE SHAREHOLDERS VOTE "FOR" APPROVAL OF THE PLAN OF
  MERGER.

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


  Voting Agreements

        In connection with the Plan of Merger, the directors and executive
  officers of Shawnee have entered into agreements to vote certain shares of
  Shawnee Common Stock beneficially owned by them in favor of the Merger.  The
  directors and executive officers of Shawnee have agreed with Keystone that
  they will vote in favor of the Merger all shares of Shawnee 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 Shawnee Common Stock over which they have
  or share voting power to be voted in favor of the Merger.  In the aggregate,
  these agreements commit 17,105 shares of Shawnee Common Stock (21.33% of the
  outstanding shares) to be voted in favor of the Merger.

        The agreements further provide that with respect to shares of Shawnee
  Common Stock owned by the Shawnee directors and executive officers as
  individuals or (to the extent of the director's or executive officer's
  proportionate voting interest) jointly with other persons (collectively,
  "Shares"), the directors and executive officers will not until the Merger has
  been consummated or the 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 Shawnee or
  Everett 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 Shawnee or Everett or (iii) for the principal purpose of
  avoiding the director's or executive officer'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 Shawnee or Everett.
    
        The agreements are applicable to the directors or executive officers
  only in their capacities as shareholders and do not affect the exercise of
  their responsibilities as directors or executive officers.  The agreements
  also do not apply to any shares of Shawnee Common Stock held by a director or
  executive officer as a trustee or other fiduciary.  No monetary or other
  compensation was paid to any Shawnee director or executive officer 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.
     

  Trust Department Shares
    
        The Trust Department of Mid-State, a wholly owned Keystone subsidiary,
  acting in a fiduciary capacity, has voting power over 6,708 shares of Shawnee
  Common Stock, representing 8.37% of the outstanding shares.  It
     
                                      -6-
<PAGE>
 
  is anticipated that these shares will be voted in favor of approval of the
  Plan of Merger.  See "Information Concerning Shawnee--Certain Beneficial
  Owners of Shawnee Common Stock."


  Opinion of Shawnee Financial Advisor
    
        Shawnee has retained Berwind to act as its financial advisor and to
  render a fairness opinion in connection with the Merger.  Berwind has rendered
  its opinion to the Board of Directors of Shawnee that, based upon and subject
  to the various considerations set forth therein, as of January 5, 1995, and as
  of June      , 1995, the Merger is fair, from a financial point of view, to
          -----
  the holders of Shawnee Common Stock.

        The full text of Berwind's opinion as of June      , 1995, which sets
                                                      -----
  forth the assumptions made, matters considered and limitations of the review
  undertaken, is attached as Annex I to this Proxy Statement/Prospectus and
  should be read in its entirety in connection with this Proxy
  Statement/Prospectus.  This section of the Proxy Statement/Prospectus sets
  forth the material terms of Berwind's opinion; however, the summary of the
  opinion of Berwind set forth herein is qualified in its entirety by reference
  to the full text of such opinion attached as Annex I to this Proxy
  Statement/Prospectus.
     
        Shawnee retained Berwind to act as Shawnee's financial advisor in
  connection with the Merger. Berwind was selected to act as Shawnee's financial
  advisor based upon its qualifications, expertise and experience.  Berwind has
  knowledge of, and experience with, Pennsylvania banking markets and banking
  organizations operating in those markets and was selected by Shawnee because
  of its knowledge of, experience with, and reputation in the financial services
  industry.
    
        In such capacity, Berwind participated in the negotiations with respect
  to the pricing and other terms of the Merger, but the decision with respect to
  the Merger exchange ratio was determined by Shawnee in the process of its
  negotiations with Keystone.  On January 5, 1995, Shawnee's Board of Directors
  approved and executed the Plan of Merger.  Berwind delivered an opinion (the
  January Opinion) to Shawnee's Board stating that, as of such date, the Merger
  was fair to the shareholders of Shawnee from a financial point of view.
  Berwind reached the same opinion as of June      , 1995.  The full text of the
                                              -----
  opinion of Berwind dated as of June      , 1995, which sets forth assumptions
                                      -----
  made, matters considered and limits on the review undertaken (the Proxy
  Opinion), is attached as Annex I to this Proxy Statement/Prospectus.  No
  limitations were imposed by Shawnee's Board of Directors upon Berwind with
  respect to the investigations made or procedures followed by Berwind in
  rendering the January Opinion or the Proxy Opinion.
     
        In rendering its Proxy Opinion, Berwind:  (i) reviewed the historical
  financial performances, current financial positions and general prospects of
  Shawnee and Keystone, (ii) reviewed the Plan of Merger, (iii) reviewed and
  analyzed the stock market performance of Keystone, (iv) studied and analyzed
  the consolidated financial and operating data of Shawnee and Keystone, (v)
  considered the terms and conditions of the proposed Merger between Shawnee and
  Keystone as compared with the terms and conditions of comparable bank mergers
  and acquisitions, (vi) met and/or communicated with certain members of
  Shawnee's and Keystone's senior management to discuss their respective
  operations, historical financial statements and future prospects and (vii)
  conducted such other financial analyses, studies and investigations as it
  deemed appropriate.
    
        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 Shawnee's
  financial forecasts reviewed by Berwind in rendering its opinion, Berwind
  assumed that such financial forecasts were reasonably prepared on bases
  reflecting the best currently available estimates and judgments of the
  management of Shawnee as to the future financial performance of Shawnee.
  Shawnee's senior management reviewed for accuracy and completeness all
  information concerning Shawnee, including any forecasts, provided to Berwind.
  Berwind did not make an independent evaluation or appraisal of the assets
  (including loans) or liabilities of Shawnee 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
     
                                      -7-

  Shawnee 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 and
  presented to Shawnee's Board in connection with the January Opinion and
  analyzed by Berwind in connection with the January and Proxy Opinions.

        Comparable Companies and Comparable Acquisition Transaction Analyses.
  Berwind compared selected financial and operating data for Shawnee with those
  of a peer group of selected banks and bank holding companies with assets
  between $50 million and $100 million, as of the most recent financial period
  publicly available, located in Pennsylvania (40 banks).  Financial data and
  operating ratios compared in the analysis of the Shawnee peer group included
  but were not limited to:  return on average assets, return on average equity,
  shareholders' equity to assets ratio and certain asset quality ratios.  The
  analysis showed Shawnee's return on average assets was 1.02% compared to the
  peer group median of 1.02%, its return on average equity was 10.09% compared
  to a peer group median of 10.53%, its equity as a percentage of assets was
  10.35% versus the peer group median of 9.89%, its nonperforming assets as a
  percentage of loans and other real estate owned was 0.50% compared to the peer
  group median of 1.26%, its nonperforming assets as a percentage of equity plus
  loan loss reserve was 2.52% compared to the peer group median of 7.08% and its
  loan loss reserve as a percentage of nonperforming assets was 97.42% compared
  to 97.31%.

        Berwind also compared selected financial, operating and stock market
  data for Keystone with those of a peer group of selected commercial banking
  companies with assets between $2.5 billion and $6 billion, as of the most
  recent period publicly available, located in Delaware, Maryland, New Jersey,
  New York, Ohio, Pennsylvania and West Virginia (11 banks).  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.  The
  analysis showed Keystone's return on average assets was 1.10% compared to the
  peer group median of 1.36%, its return on average equity was 11.73% compared
  to a peer group median of 14.12%, its shareholders' equity as a percentage of
  assets was 9.04% versus the peer group median of 8.82%, its nonperforming
  assets as a percentage of loans and other real estate owned was 1.25% compared
  to the peer group median of 1.09%, its nonperforming assets as a percentage of
  shareholders' equity plus loan loss reserve was 9.58% compared to the peer
  group median of 6.83% and its loan loss reserve as a percentage of
  nonperforming assets was 155.94% compared to 105.64%.

        In addition, the analysis showed that Keystone's price per share ($30.25
  on the date of the January Opinion) as a percentage of book value per share
  was 173.35% compared to the peer group median of 157.26%, its price per share
  as a percentage of tangible book value was 174.75% compared to the peer group
  median of 162.40% and its price per share as a multiple of latest twelve
  months earnings per share of 14.00 compared to the peer group median of 11.25
  times.

        Berwind also compared the multiples of book value, tangible book value
  and latest twelve months' earnings inherent to the Merger with the multiples
  paid in recent acquisitions of banks and bank holding companies that Berwind
  deemed comparable.  These ratios are generally considered significant by
  analysts when evaluating a bank acquisition transaction.  The transactions
  deemed comparable by Berwind included both interstate and intrastate
  acquisitions announced since January 1, 1994, in which the selling
  institution's assets were between $50 million and $100 million.

        Berwind compared seventy-six transactions located throughout the country
  and analyzed those transactions in three groups: a national group (76 banks),
  a regional group (14 banks) and a performance group (25 banks).  The national
  group included transactions throughout the United States; the regional group
  included transactions in Maryland, New Jersey, Pennsylvania, Virginia and West
  Virginia; and the performance group included transactions involving banks with
  year-to-date return on average assets greater than 0.75% and less than 1.25%.
  The median values calculated for price per share as a percentage of book value
  per share was 173.98%, 178.58% and 170.32%

                                      -8-
<PAGE>
 
  for the national, regional and performance group, respectively; the range of
  price per share as a percentage of tangible book value per share was 174.18%,
  178.59% and 170.32% for the national, regional and performance group,
  respectively; and the range of the price per share as a multiple of latest
  twelve months earnings per share was 14.17, 18.11 and 17.95 times earnings for
  the national, regional and performance group, respectively.

        These medians compare to the Merger's price per share as a percentage of
  book value per share, price per share as a percentage of tangible book value
  per share, and price per share as a multiple of latest twelve months earnings
  per share of 198.56%, 198.56% and 22.34 times, respectively.  No company or
  transaction, however, used in this analysis is identical to Shawnee, Keystone
  or the 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
  Shawnee could produce over a five-year period under different assumptions as
  to dividend pay out levels, if Shawnee performed in accordance with various
  earnings growth forecasts.  Berwind also estimated the ending value for
  Shawnee's Common Stock after the five-year period by applying a range of
  earnings multiples from 8 to 12 to Shawnee's terminal year earnings.  The
  range of multiples used reflected a variety of scenarios regarding the growth
  and profitability prospects of Shawnee.  The dividend streams and terminal
  values were then discounted to present value using discount rates ranging from
  10% to 20%, reflecting different assumptions regarding the rates of return
  required by holders or prospective buyers of Shawnee's Common Stock.  This
  analysis is generally considered significant by analysts in that it provides
  an estimate of the value of the bank if it were to remain independent under
  various earnings and dividends scenarios.  The range of present values per
  fully diluted share of Shawnee common stock resulting from these assumptions
  were $56 to $121 if earnings per share and dividends grow at 5% per annum; $63
  to $136 at assumed growth rates of 7.5%; and $70 to $152 at assumed rates of
  growth of 10% per annum.
     
        Pro Forma Contribution Analysis.  Berwind analyzed the changes in the
  amount of earnings, book value and dividends represented by one share of
  Shawnee Common Stock prior to the Merger and 6.25 shares of Keystone Common
  Stock after the Merger.  The analysis considered, among other things, the
  changes that the Merger would cause to Shawnee's earnings per share, book
  value per share and indicated dividends.  On a per share equivalent basis,
  Shawnee's earnings per share increase 19% from $11.51 to $13.75, its tangible
  book value per share increases 13% from $95.22 to $107.91 and its dividend per
  share increases 215% from $2.70 to $8.50 per share.  In reviewing the pro
  forma combined earnings, equity and assets of Keystone based on the Merger
  with Shawnee, Berwind analyzed the contribution that Shawnee would have made
  to the combined company's earnings, equity and assets as of and for the period
  ended December 31, 1994.  Berwind also reviewed the percentage ownership that
  Shawnee's stockholders would hold in the combined company.

        In connection with rendering its January Opinion and Proxy 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 Merger was to some extent a subjective one based on the experience and
  judgment of Berwind and not merely the result of mathematical analysis 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 Shawnee'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 weighting by Berwind than any other
  analysis.  As a result of its consideration of the aggregate of all factors

                                      -9-
<PAGE>
 
  present and analyses performed, Berwind reached the conclusion, and opined,
  that terms of the Merger as set forth in the Plan of Merger, are fair from a
  financial point of view to Shawnee and its shareholders.

        In connection with delivering its Proxy Opinion, Berwind updated certain
  analyses described above to reflect current market conditions and events
  occurring since the date of the Plan of Merger.  Such reviews and updates led
  Berwind to conclude that it was not necessary to change the conclusions it had
  reached in connection with rendering the January Opinion.

        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, private placements, and valuations for various other purposes
  and in the determination of adequate consideration in such transactions.

        Berwind's Proxy 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 Proxy Opinion was delivered; events occurring after the date of
  its Proxy Opinion could materially affect the assumptions used in preparing
  its Proxy Opinion.  Berwind has not undertaken to reaffirm and revise its
  Proxy Opinion or otherwise comment upon any events occurring after the date
  thereof.

        In delivering its January Opinion and Proxy Opinion, Berwind assumed
  that in the course of obtaining the necessary regulatory and governmental
  approvals for the Merger, no restriction will be imposed on Keystone that
  would have a material adverse effect on the contemplated benefits of the
  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 Merger.
    
        During Berwind's presentation, and upon its conclusion, Shawnee's Board
  and its counsel asked questions to better understand the assumptions and
  limitations of the methodologies employed by Berwind in its analyses.
  Although the Board relied upon the expertise of Berwind as to the assumptions
  employed by Berwind, the Board made its own determination as to the
  reasonableness of Berwind's analyses and as to the adequacy of the
  consideration offered by Keystone.
     
        Pursuant to the terms of the engagement letter dated October 25, 1994,
  Shawnee has paid Berwind $42,500 for acting as financial advisor in connection
  with the Merger, including delivering its January and Proxy Opinions.  In
  addition, Shawnee has agreed to pay Berwind approximately $29,000 upon the
  consummation of the Merger and to reimburse Berwind for its reasonable out-of-
  pocket expenses.  Whether or not the Merger is consummated, Shawnee 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 Proxy Opinion of Berwind as of June      , 1995,
                                                                 -----
  which set forth assumptions made and matters considered, is attached hereto as
  Annex I to this Proxy Statement/Prospectus.  Shawnee's stockholders are urged
  to read the Proxy Opinion in its entirety. Berwind's Proxy Opinion is directed
  only to the consideration to be received by Shawnee stockholders in the Merger
  and does not constitute a recommendation to any holder of Shawnee Common Stock
  as to how such holder should vote at the Shawnee Special Meeting.

        THE ABOVE DISCUSSION SETS FORTH THE MATERIAL TERMS OF BERWIND'S PROXY
  OPINION.  HOWEVER, THE FOREGOING PROVIDES ONLY A SUMMARY OF THE PROXY OPINION
  OF BERWIND AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF
  THAT OPINION, WHICH IS SET FORTH IN ANNEX I TO THIS PROXY
  STATEMENT/PROSPECTUS.

  Conversion of Shawnee Shares
    
        Exchange Ratio.  On the effective date of the Merger, each outstanding
  share of Shawnee Common Stock (other than shares subject to dissenters'
  rights) will be converted into 6.25 shares of Keystone Common Stock, with cash
  to be paid in lieu of the issuance of any fractional share.  On June 20, 1995,
  the closing sale price for Keystone Common Stock reported on the NASDAQ
  National Market System was $28.125.
     
        Surrender of Certificates.  As promptly as practicable after the
  effective date of the Merger, Keystone will send to each shareholder of record
  of Shawnee immediately prior to the Merger a letter of transmittal containing
  instructions on how to effect the exchange of Shawnee Common Stock
  certificates for certificates representing the shares of Keystone Common Stock
  into which their shares have been converted.  Shawnee 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 Merger will apply to all whole shares of Keystone Common Stock into
  which shares of Shawnee Common Stock have been converted in the Merger.
  However, no former Shawnee shareholder will be entitled to receive any such
  dividend until such shareholder's Shawnee 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 Merger.  Instead, each Shawnee
  shareholder who surrenders for exchange Shawnee 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 $29.25 for
  one whole share of Keystone Common Stock.

        Unexchanged Certificates.  On the effective date of the Merger, the
  stock transfer books of Shawnee will be closed, and no further transfers of
  Shawnee Common Stock will be made or recognized.  Certificates for Shawnee
  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 Merger becomes effective and any former Shawnee shareholder does
  not surrender his or her Shawnee 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
  Shawnee 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 Shawnee Common Stock--Keystone Shareholder Rights Plan") shall have
  occurred prior to the effective date of the Merger, then each share of
  Keystone Common Stock issued in the 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 Merger that Keystone take one of the
  actions set forth under "Conditions to the Merger" below.
    
        Adjustment of Exchange Ratio.  The 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 Shawnee Common Stock which occurs prior to the
  Merger.  Although no such
     
                                      -11-
<PAGE>
 
     
  adjustments are anticipated, any such adjustment would be proportionate and
  therefore would not decrease the value of the consideration per preadjustment
  share of Shawnee Common Stock to be received by Shawnee shareholders in the
  Merger.
     

  Tax Consequences to Shawnee Shareholders
    
        Federal Income Tax.  The Plan of Merger requires as a condition to the
  Merger that each party receive a written opinion of counsel or of independent
  public accountants that:
     
              (1)  The 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 Shawnee 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 Shawnee as
        a result of the Merger;

              (3)  Except for cash received in lieu of fractional shares, no
        gain or loss will be recognized by holders of Shawnee 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 Shawnee will be the same as the basis of
        the shares of Shawnee Common Stock exchanged therefor; and

              (5)  The holding period of the shares of Keystone Common Stock
        received by the shareholders of Shawnee will include the period during
        which the Shawnee Common Stock exchanged therefor was held by the
        Shawnee shareholder, provided that the Shawnee 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 Shawnee on the exchange of their shares for whole shares of
  Keystone Common Stock.  However, gain or loss will be recognized by Shawnee
  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 Shawnee 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
  Shawnee Common Stock was a capital asset in the hands of the shareholder.

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

        Where a Shawnee shareholder exercises dissenters' rights and receives
  cash in exchange for Shawnee Common Stock, the cash will be treated as
  received by the shareholder as a distribution in redemption of the Shawnee
  Common Stock subject to the provisions and limitations of Section 302 of the
  Code.  The cash received by a dissenting Shawnee shareholder will be treated
  as if the shares had been sold to Shawnee 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

                                      -12-
<PAGE>
 
  being taxed as a dividend, a Shawnee shareholder should consult with his own
  personal tax advisor as to the federal, state and local tax consequences of
  exercising dissenters' rights.

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

        The foregoing is intended only as a summary of certain federal income
  tax and Pennsylvania personal income tax consequences of the 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 Merger.  Among other
  things, the summary does not address state income tax consequences in states
  other than Pennsylvania or any local taxes.  Accordingly, it is recommended
  that Shawnee 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
  Merger.


  Boards of Directors Following the Merger

        No change will be made by reason of the Merger in the Board of Directors
  of Keystone.  At the time the Bank Merger becomes effective, L. Frank Bittner,
  currently Chairman of the Board of Directors of Shawnee, will be added to the
  Board of Directors of Mid-State to serve for a term or terms expiring not less
  than one year after the Merger.  The Board of Directors of Mid-State presently
  consists of 19 directors.  If prior to the Merger Mr. Bittner becomes unable
  or declines to serve as a director of Mid-State, Shawnee shall be entitled to
  designate a substitute director acceptable to Keystone.

  Interests of Certain Persons in the Transaction
    
        Arrangements with Shawnee Directors and Executive Officers.  As
  indicated under the preceding caption, following the Merger L. Frank Bittner,
  currently Chairman of the Board of Directors of Shawnee and Everett, will
  become a director of Mid-State.  As a director of Mid-State, Mr. Bittner will
  receive the same fees as other Mid-State directors.   Effective July 1, 1995,
  those fees will consist of an annual retainer of $3,500, payable in shares of
  Keystone Common Stock, plus $500 per Board meeting and $200 per Board
  Committee meeting attended.  Chairmen of Board Committees receive an
  additional $500 annual retainer, and directors who participate by telephone in
  Board or Board Committee meetings receive $100 per meeting.

        Mid-State has indicated its intention to offer Samuel K. Bohn, the
  President and a director of Shawnee and Everett, $50,000 per year for a two-
  year period following the Merger to assist Mid-State in the post-Merger
  transition and/or in return for a covenant not to compete.

        It is intended that following the Merger Ralphard L. Black, Vice
  President of Shawnee and Executive Vice President of Everett, will be employed
  as a Vice President of Mid-State.  There will be no change by reason of the
  Merger in Mr. Black's salary, which is currently $65,000 per year.
     
                                      -13-
<PAGE>
 
     
        It is not intended that any of the remaining directors and executive
  officers of Shawnee, none of whom are employees, will be retained by Keystone
  or Mid-State following the Merger.  No severance or similar payments will be
  made to such persons.
     
        Shawnee Directors' and Officers' Indemnification and Insurance.
  Keystone has agreed that following the Merger it will perform the obligations
  of Shawnee under Shawnee's By-Laws concerning the indemnification of Shawnee's
  directors and officers with respect to events occurring at or prior to the
  Merger and will cause Mid-State to perform the obligations of Everett under
  its By-Laws concerning the indemnification of the directors and officers of
  Everett with respect to events occurring at or prior to the Bank Merger.  The
  By-Laws of Shawnee generally require Shawnee to indemnify its directors and
  officers against expenses, including attorneys' fees, judgments, fines and
  amounts paid in settlement actually and reasonably incurred in connection with
  any civil, criminal, administrative or investigative proceeding to which such
  person is a party by reason of having served in such capacity 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 Shawnee and, in the case of any criminal
  proceeding, had no reasonable cause to believe that his conduct was unlawful.
  In the case of a suit by or in the right of Shawnee, no indemnification may be
  made as to any claim, issue or matter as to which the director or officer
  shall have been found liable for misconduct in the performance of his duty to
  Shawnee.  The By-Laws of Keystone and its subsidiaries contain similar
  provisions regarding the indemnification of directors and officers.  The By-
  Laws of Everett provide that directors and officers may be indemnified for
  reasonable expenses actually incurred in connection with any proceeding to
  which such person is a party by reason of having served in such capacity,
  except that no indemnification shall be made as to any matter as to which such
  person is found to have been guilty of or liable for gross neglect of duty or
  willful misconduct or to have committed an act or failed to perform a duty for
  which there is a common law or statutory liability, and no person shall be
  indemnified with respect to any matter which has been the subject of a
  compromise settlement unless approved by the parent holding company.

        Keystone has also agreed to use its best efforts to obtain a one-year
  tail policy of directors' and officers' liability insurance for the directors
  and officers of Shawnee and Everett with respect to events which occurred
  prior to the Merger.  Such insurance is to be provided on terms substantially
  equivalent to Shawnee's current directors' and officers' liability policy,
  which has a $6 million coverage limit, except that the maximum premium
  Keystone must pay for such policy is limited to $20,000.  In addition, for
  claims made within three years following the Merger and at a time when such
  tail policy is not in effect, Keystone will indemnify the former directors and
  officers of Shawnee and Everett against any claim or liability, whether or not
  indemnifiable under the By-Laws of Shawnee or Everett, if and to the extent
  that such claim or liability would have been covered under Shawnee's current
  policy of directors' and officers' liability insurance if such policy were
  then in effect.

        Employee Matters.  The Plan of Merger provides that Keystone will
  consider Everett employees for employment within the Keystone organization and
  that following the Merger Keystone will permit Everett employees employed by
  Keystone and its subsidiaries to participate on an equal basis with other
  similarly situated employees in Keystone's internal open position posting and
  application procedures.  Shawnee and Everett employees who become employees of
  Keystone and its subsidiaries shall be provided employee benefits, including
  retirement, health and welfare benefits, life insurance, incentive
  compensation and vacation and severance arrangements, no less favorable than
  those provided to other similarly situated employees.  With respect to group
  health benefits, Keystone will waive any otherwise applicable waiting periods
  and preexisting conditions if at the time of the Merger the employee was
  covered under a similar plan of Shawnee.  Following the Merger, Keystone and
  Mid-State will perform the respective obligations of Shawnee and Everett with
  respect to vested benefits accrued through the date of the Merger under
  Everett's retirement and profit sharing plans.


  Warrant Agreement

        In connection with the Plan of Merger, Keystone and Shawnee have entered
  into an Investment Agreement, and Shawnee has issued to Keystone a Warrant
  thereunder (collectively, the "Warrant Agreement"), entitling Keystone to
  purchase up to approximately 19.9% of Shawnee's outstanding Common Stock upon
  the

                                      -14-
<PAGE>
 
  occurrence of certain events described below.  The Warrant Agreement covers
  19,921 shares of Shawnee Common Stock at an exercise price of $182.81 per
  share.

        The Warrant Agreement is designed to compensate Keystone for its risks,
  costs and expenses and the commitment of resources associated with the Plan of
  Merger in the event the Merger is not consummated due to an attempt by a third
  person to gain control of Shawnee.  See also "Expenses" below.  Keystone may
  not exercise or sell its Warrant except upon (i) a willful breach by Shawnee
  of the Plan of Merger, (ii) the failure of Shawnee's shareholders to approve
  the Plan of Merger after the announcement by a third person of a bona fide
  proposal to acquire 10% or more of the Shawnee Common Stock, to acquire, merge
  or consolidate with Shawnee or to acquire substantially all of Shawnee's
  assets or Everett, (iii) the acquisition by a third person of 1% or more of
  the outstanding Shawnee Common Stock if after such acquisition such person
  would beneficially own 10% or more of the Shawnee 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 Shawnee Common Stock or
  (v) the entry by Shawnee into an agreement or understanding with a third
  person for the third person to acquire, merge or consolidate with Shawnee or
  to acquire substantially all of its assets or Everett (each of the foregoing
  is hereafter referred to as a "Warrant Event").  No Warrant Event has occurred
  as of the date of this Proxy Statement/Prospectus, and neither Keystone nor
  Shawnee 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 Shawnee and is intended to increase the likelihood that the
  Merger will be consummated in accordance with the terms set forth in the 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 Shawnee 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 Shawnee Common Stock purchased thereunder
  would be subject to a right of first refusal by Shawnee unless sold in a
  public offering registered under the Securities Act.  Shawnee agrees in the
  Warrant Agreement to effect such registration if requested.

        Keystone may require Shawnee to redeem the Warrant or any shares of
  Shawnee Common Stock purchased thereunder if (i) a third person acquires
  beneficial ownership of 50% or more of the outstanding Shawnee Common Stock or
  (ii) a third person acquires, merges or consolidates with Shawnee or acquires
  substantially all of its assets or Everett (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 Shawnee
  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 Shawnee the right
  to repurchase shares of Shawnee 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 Shawnee or Everett.
    
        The foregoing description is a summary of the material terms 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 Proxy Statement/Prospectus by reference to such filing.

  Inconsistent Activities

        Shawnee has agreed in the Plan of Merger that unless and until the
  Merger has been consummated or the Plan of Merger has been terminated in
  accordance with its terms, Shawnee will not (i) solicit or encourage any
  proposals by a third person to acquire more than 1% of the Shawnee Common
  Stock, any stock of Everett or any significant portion of its or Everett'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 its or Everett'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, Shawnee 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 Shawnee'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 Shawnee becomes aware of any offer or proposed offer
  to acquire any shares of Shawnee or Everett or any significant portion or its
  or Everett's assets, or of any other matter which is reasonably likely to
  adversely affect the parties' ability to consummate the Merger, Shawnee is
  required to give immediate notice thereof to Keystone.


  Conduct of Shawnee Business Pending the Merger

        Shawnee has agreed in the Plan of Merger that, pending consummation of
  the Merger, Shawnee and Everett will conduct their businesses only in the
  ordinary course and that, except as consented to by Keystone, Shawnee and
  Everett 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; (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.


  Shawnee Dividend Limitation

        Shawnee has agreed in the Plan of Merger that pending the Merger it will
  not declare or pay dividends on the Shawnee Common Stock other than its
  regular $2.70 per share dividend declared in 1994 ($0.25 per share declared
  June 14, 1994, payable July 1, 1994, and $2.45 per share declared December 13,
  1994, payable January 1, 1995).  In 1995, Shawnee has agreed not to declare or
  pay dividends exceeding $2.70 per share over the twelve month period, and has
  further agreed to prorate the dividend based on the $2.70 annual amount, with
  the prorated dividend to be payable shortly prior to the Merger.


  Conditions to the Merger

        In addition to shareholder approval, the Merger is contingent upon the
  satisfaction of a number of other conditions, including (i) approval of the
  Merger by the Federal Reserve Board and the Pennsylvania Department of Banking
  without conditions deemed unduly burdensome by Keystone and the absence of any
  suit by the United States to prohibit the Merger filed within the 30 days
  following Federal Reserve Board approval, (ii) receipt of the tax opinion
  described above (see "Tax Consequences"), (iii) receipt of the agreements of
  Shawnee affiliates described below under "Restrictions on Resales by Shawnee
  Affiliates" and (iv) the absence of any judicial or administrative order
  prohibiting or adversely affecting the Merger or any pending or threatened
  litigation or administrative proceeding challenging the Merger.  Keystone's
  obligation to consummate the Merger is subject to the additional conditions
  that the Bank Merger shall have been approved by the Federal Deposit Insurance
  Corporation ("FDIC") and the Pennsylvania Department of Banking without
  conditions deemed unduly burdensome by Keystone and that no suit to prohibit
  the Bank Merger shall have been filed by the United States during the 30

                                      -16-
<PAGE>
 
  days following FDIC approval.  In addition, unless waived, each party's
  obligation to consummate the Merger is subject to the performance by the other
  party of its obligations under the 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 Shawnee 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 ratio for converting
  Shawnee Common Stock into Keystone Common Stock in the Merger shall have been
  proportionately adjusted as provided in the 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
  Shawnee Common Stock upon consummation of the Merger.


  Representations and Warranties

        The representations and warranties of Keystone and Shawnee contained in
  the Plan of Merger relate, among other things, to the organization and good
  standing of Keystone, Shawnee and their subsidiaries; the capitalization of
  Keystone and Shawnee and ownership of their subsidiaries; the authorization by
  Keystone and Shawnee of the 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,
  1994; the absence of undisclosed litigation; compliance with laws; and the
  accuracy of this Proxy Statement/Prospectus and of Keystone's Registration
  Statement of which it is a part.  Additional representations and warranties by
  Shawnee concern payment of taxes; title to properties; the absence of
  undisclosed equity investments, employment contracts, employee benefit plans
  or material contracts; and the absence of certain potential environmental
  liabilities.  None of the representations and warranties contained in the Plan
  of Merger will survive the consummation of the Merger.


  Amendment, Waiver and Termination

        Notwithstanding prior shareholder approval, the Plan of Merger may be
  amended in any respect by written agreement between the parties, except that
  after shareholder approval no amendment may change the rate of exchange of
  Shawnee Common Stock for Keystone Common Stock in the Merger or change the
  form of such consideration.  Keystone or Shawnee 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 Plan of Merger;
  and (iv) waive any condition precedent to its obligations under the Plan of
  Merger other than approval by the shareholders of Shawnee of the Plan of
  Merger, governmental regulatory approvals required to consummate the Merger,
  securities registration requirements incident to the issuance of Keystone
  Common Stock in the Merger, the receipt of the tax opinions described above
  and the absence of any judicial or administrative order prohibiting the
  Merger.

        Notwithstanding prior shareholder approval, the Plan of Merger may be
  terminated without liability of either party at any time prior to
  effectiveness of the Merger (i) by mutual consent of Keystone and Shawnee 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 Shawnee
  shareholders to approve the Plan of Merger at the Special Meeting, (c) a final
  judicial or regulatory determination denying any regulatory approval required
  for the Merger or imposing conditions or requirements which Keystone
  determines to be unduly burdensome or (d) failure to satisfy prior to
  September 30, 1995 any condition to its obligations to consummate the 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.  The
  deadline for satisfying the conditions to the Merger will be extended to
  December 31, 1995 if the failure to satisfy such conditions results from a
  delay in receiving Federal Reserve Board approval.

                                      -17-
<PAGE>
 
        Shawnee may terminate the Plan of Merger if (i) the average of the
  closing bid prices for Keystone Common Stock on the NASDAQ National Market
  System for the 10 consecutive trading days ending on the sixth trading day
  prior to the closing date for the Merger (the "Valuation Period") shall be
  less than $24.86 (85% of the closing bid price on January 4, 1995) and (ii)
  the number obtained by dividing such average Keystone bid price by $29.25 (the
  closing bid price on January 4, 1995) is less than 85% of the number obtained
  by dividing the average of the NASDAQ Combined Bank Index for the Valuation
  Period by 708.30 (such index at January 4, 1995).


  Dissenters' Rights of Shawnee Shareholders

        A holder of shares of Shawnee Common Stock is entitled to exercise the
  rights of a dissenting shareholder under Subchapter D of Chapter 15
  ("Subchapter D") of the Pennsylvania Business Corporation Law of 1988, as
  amended (the "BCL"), to object to the Plan of Merger and make written demand
  that Shawnee or Keystone, as the surviving corporation in the Merger, pay in
  cash the fair value of the shares held as determined in accordance with such
  statutory provisions.  The following summary does not purport to be a complete
  statement of the provisions of Subchapter D and is qualified in its entirety
  by reference to such statutory provisions, which (together with Section 1930
  of the BCL) are set forth in full as Annex II to this Proxy
  Statement/Prospectus.

        A record holder of shares of Shawnee Common Stock may assert dissenters'
  rights as to fewer than all such shares registered in his name only if he
  dissents with respect to all the shares beneficially owned by any one person
  and discloses the name and address of the person or persons on whose behalf he
  dissents.

        A beneficial owner of shares of Shawnee Common Stock who is not the
  record holder of such shares is entitled to assert dissenters' rights with
  respect to shares held on his behalf only if he submits to Shawnee no later
  than the time of the assertion of dissenters' rights a written consent of the
  record holder of such shares.  A beneficial owner may not dissent with respect
  to less than all shares of Shawnee Common Stock owned by him, whether or not
  the shares so owned by him are registered in his name.

        In the event that a holder of shares of Shawnee Common Stock wishes to
  dissent to the Plan of Merger and obtain payment of the fair value of his
  shares, he must satisfy all the following conditions to acquire any right to
  payment of the fair value of his shares under Subchapter D:

              (1)  He must file with Shawnee, prior to the vote on the Plan of
        Merger, a written notice of intention to demand that he be paid the fair
        value for his shares if the Plan of Merger is effectuated.  Neither a
        proxy indicating a vote against, nor a vote in person against, the Plan
        of Merger shall constitute the written notice required.

              (2)  He must effect no change in the beneficial ownership of his
        shares from the date of filing such written notice continuously through
        the effective date of the Merger.

              (3)  He must not vote his shares in favor of the Plan of Merger.
        Neither an abstention from voting with respect to, nor failure to vote
        in person or by proxy against approval of, the Plan of Merger
        constitutes a waiver of the rights of a dissenting shareholder.
        However, a signed proxy that is returned without any instruction as to
        how the proxy should be voted will be voted in favor of approval of the
        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 shall not acquire any
  right to payment of the fair value of his shares under Subchapter D.  Each
  written notice of intention to demand payment must clearly state that the
  shareholder intends to demand that he be paid the fair value of his shares if
  the Plan of Merger is effectuated, must provide the name, address and
  telephone number of the shareholder and should be sent to Shawnee Financial
  Services Corporation, 115 East Main Street, P.O. Box 149, Everett,
  Pennsylvania 15537, Attention:  Samuel K. Bohn, President.  A dissenting
  shareholder shall retain all other rights of a Shawnee shareholder until those
  rights are modified by effectuation of the Plan of Merger.

                                      -18-
<PAGE>
 
        If the Plan of Merger is approved by the shareholders of Shawnee by the
  required vote at the Special Meeting, Shawnee or Keystone shall mail a notice
  to all dissenters who gave due notice of intention to demand payment of the
  fair value of their shares and who did not vote in favor of the Plan of
  Merger.  Such notice shall:

              (1)  State where and when a demand for payment must be sent and
        certificates representing Shawnee shares must be deposited in order to
        obtain payment.  The time set for receipt of the demand and deposit of
        shares shall be not less than 30 days from the mailing of the notice.

              (2)  Supply a form for demanding payment that includes a request
        for certification of the date on which the shareholder, or the person on
        whose behalf the shareholder dissents, acquired beneficial ownership of
        the shares.

              (3)  Be accompanied by a copy of Subchapter D.

        The dissenting shareholder must make written demand for payment of the
  fair value of the shares with respect to which dissent is made and must
  deposit certificates representing such shares in accordance with the terms of
  the notice to demand payment sent by Shawnee or Keystone.  A shareholder who
  fails to timely demand payment, or fails to timely deposit certificates, as
  required by the notice to demand payment, shall not have any right under
  Subchapter D to receive payment of the fair value of his shares.

        Within 60 days after the date set for demanding payment and depositing
  certificates, if the Plan of Merger has not been effectuated, Shawnee or
  Keystone shall return any certificates that have been deposited.  When
  deposited certificates have been returned, Shawnee or Keystone may at any
  later time send a new notice to demand payment, which will have a like effect
  as the original notice.

        Promptly after effectuation of the Plan of Merger, or upon timely
  receipt of demand for payment if the Plan of Merger has already been
  effectuated, Keystone shall either remit to dissenters who have made demand
  and have deposited their certificates the amount that Keystone estimates to be
  the fair value of the shares, or shall give written notice that no remittance
  will be made.  The remittance or notice shall be accompanied by:  (1) the
  closing balance sheet and statement of income of Shawnee for the fiscal year
  ending not more than 16 months before the date of remittance or notice,
  together with the latest available interim financial statements; (2) a
  statement of Keystone's estimate of the fair value of the shares; and (3) a
  notice of the right of the dissenter to demand payment or supplemental
  payment, as the case may be, accompanied by a copy of Subchapter D.  If
  Keystone does not remit the amount of its estimate of the fair value of the
  shares, it shall return any certificates that have been deposited.  Keystone
  may make a notation on any such certificates that demand for payment has been
  made.

        If Keystone gives notice of its estimate of the fair value of the
  shares, without remitting such amount, or remits payment of its estimate of
  the fair value of a dissenter's shares and the dissenter believes that the
  amount stated or remitted is less than the fair value of his shares, the
  dissenter may send to Keystone his own estimate of the fair value of the
  shares, which shall be deemed a demand for payment of such amount or the
  deficiency.

        Where the dissenter does not file his own estimate within 30 days after
  the mailing by Keystone of its remittance or notice, the dissenter shall be
  entitled to no more than the amount stated on the notice or remitted to him by
  Keystone.

        Within 60 days after the latest of (1) effectuation of the Plan of
  Merger, (2) timely receipt of any demands for payment, or (3) timely receipt
  of any estimates by dissenters of the fair value of their shares, if any
  demands for payment remain unsettled, Keystone may file in court an
  application for relief requesting that the fair value of the shares be
  determined by the court.  All dissenting shareholders, wherever residing,
  whose demands have not been settled shall be made parties to the proceeding.
  A copy of the application for relief shall be served on each such dissenter.

                                      -19-
<PAGE>
 
        The court may appoint an appraiser to receive evidence and recommend a
  decision on the issue of fair value, which appraiser shall have such power and
  authority as may be specified by the court.

        Each dissenter who is made a party to the proceeding shall be entitled
  to recover the amount, if any, by which the fair value of his shares is found
  to exceed the amount, if any, previously remitted by Keystone, plus interest.

        If Keystone fails to file an application for relief, any dissenter who
  made a demand and who has not already settled his claim against Keystone may
  do so in the name of Keystone at any time within 30 days after the expiration
  of the 60-day period.  If a dissenter does not file an application within such
  30-day period, each dissenter entitled to file an application shall be paid
  Keystone's estimate of the fair value of his shares and no more, and may bring
  an action to recover any amount not previously remitted.

        In general, the costs and expenses of any valuation proceeding,
  including the reasonable compensation and expenses of the appraiser appointed
  by the court, shall be determined by the court and assessed against Keystone.
  However, any part of the costs and expenses may be apportioned and assessed as
  the court deems appropriate against all or some of the dissenting shareholders
  who are parties to the proceeding and whose action in demanding supplemental
  payment the court finds to be dilatory, obdurate, arbitrary, vexatious or in
  bad faith.

        Fees and expenses of counsel and of experts for the respective parties
  may be assessed as the court deems appropriate against Keystone and in favor
  of any or all dissenters if Keystone or Shawnee failed to comply substantially
  with the requirements of Subchapter D.  Such fees and expenses may be assessed
  against either Keystone or a dissenter, in favor of any other party, if the
  court finds that the party against whom the fees and expenses are assessed
  acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner
  in respect to the rights provided by Subchapter D.  If the court finds that
  the services of counsel for any dissenter were of substantial benefit to other
  dissenters similarly situated and should not be assessed against Keystone, it
  may award to those counsel reasonable fees to be paid out of the amounts
  awarded to the dissenters who were benefited.

        SHAWNEE 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 SUBCHAPTER D.


  Restrictions on Resales by Shawnee Affiliates

        The shares of Keystone Common Stock issuable in the Merger have been
  registered under the Securities Act, and such shares will generally be freely
  tradeable by the Shawnee shareholders who receive Keystone shares as a result
  of the Merger.  However, this registration does not cover resales by Shawnee
  shareholders who may be deemed to control or be under common control with
  Shawnee and who therefore may be deemed "affiliates" of Shawnee 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 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 Shawnee
  will notify those persons whom it believes may be such affiliates.

        The Plan of Merger requires as a condition to the Merger that each such
  Shawnee affiliate enter into an agreement not to sell the shares of Keystone
  Common Stock acquired in the Merger except in accordance with the requirements
  of the Securities Act and the regulations thereunder.

                                      -20-

  Effect of Certain Transactions Involving Keystone

        The 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 Plan
  of Merger and the 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 Plan
  of Merger shall be appropriately amended so that Shawnee shareholders will
  receive in the Merger, for each share of Shawnee Common Stock held, 6.25 times
  the consideration paid in such transaction for shares of Keystone Common
  Stock.  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,
  Shawnee is not required to amend or waive this condition.

        As of the date of this 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.


  Expenses
    
        Keystone and Shawnee will each pay 50% of (1) all printing costs related
  to securities registration and the solicitation of proxies for the Special
  Meeting, (2) all filing fees and legal and accounting fees and expenses
  related to the tax opinion referred to above and to the regulatory approvals
  required for the Merger and (3) the fees of Berwind Financial Group, L.P.,
  Shawnee's financial advisor, except that the portion of such fees payable by
  Keystone shall be limited to $26,250.  Each party will pay its own other
  expenses incurred in connection with the Plan of Merger.  However, the Plan of
  Merger provides that if the Merger is not consummated as a direct or indirect
  consequence of a change of control of Shawnee, Shawnee shall reimburse
  Keystone for all of its reasonable out-of-pocket expenses incurred in
  connection with the Plan of Merger.
     

  Effective Date of the Merger
    
        It is presently anticipated that if the Plan of Merger is approved by
  the shareholders of Keystone and Shawnee, the Merger will become effective in
  the third quarter of 1995.  However, as noted above, consummation of the
  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 Merger
  will be satisfied or, if satisfied, that they will be satisfied in time to
  permit the Merger to become effective within the anticipated time frame.  In
  addition, as also noted above, Keystone and Shawnee retain the power to
  abandon the Merger or to extend the time for performance of conditions or
  obligations necessary to its consummation, notwithstanding prior shareholder
  approval.
     

  Accounting Treatment

        Normally, the Merger would be accounted for by Keystone under the
  pooling-of-interests method of accounting, which views the Merger as a uniting
  of the separate ownership interests of Keystone and Shawnee through an
  exchange of shares.  However, if the number of treasury shares purchased by
  Keystone under its share repurchase program exceeds certain limits, Keystone
  may be required to account for the Merger under the purchase method of
  accounting.

        Under the pooling-of-interests method, the financial statements of the
  merged company normally reflect the combined historical financial data of the
  merging companies, subject only to certain adjustments to the capital accounts
  to reflect the share exchange of shares.  However, due to the immaterial
  impact of the Merger on

                                      -21-
<PAGE>
 
  Keystone's previously reported results, it is anticipated that Keystone's
  historical financial statements would not be restated if the Merger is
  accounted for as a pooling-of-interests.

        If the Merger is accounted for under the purchase method, the assets and
  liabilities of Shawnee acquired in the Merger will be recorded by Keystone for
  financial reporting purposes at their market values as of the date of the
  Merger, and any excess of the consideration paid over the net market values
  acquired will be recorded and amortized as goodwill.
    
        Pro forma financial information concerning the Merger is not included
  herein since the addition of Shawnee under either accounting method would not
  have materially affected the Keystone historical financial information as
  presented.

                 SHAWNEE MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
    
General

     The disclosures called for by SEC Industry Guide 3, which detail many
aspects of a banking company's financial condition and results of operations,
are generally required by the SEC for banking companies subject to the SEC's
periodic reporting requirements. Shawnee is not subject to the SEC's periodic
reporting requirements. Shawnee does not in its ordinary course maintain the
information necessary to compile many of the disclosures required pursuant to
Guide 3 and compiling such information would be very expensive and time
consuming. Therefore, Shawnee is not providing all disclosures required by Guide
3 to shareholders. Shawnee believes it is providing shareholders with all
material information concerning the company and its operations (including
elements of the bank's loan portfolio) for shareholders to make an investment
decision in favor or against the proposed Merger.

1994 versus 1993

     Net Income

     Net income decreased year to year by 12.86% from 834,494 in 1993 to
$727,198 in 1994. The principal reasons for this decline were an increased cost
of funds, resulting from several interest rate hikes by the Federal Reserve
Board during the year, and an increase in certain expenses, relating to
increased staff levels and the phase-in of certain newer technologies. The bank
remained solidly profitable, however, although net income per share fell from
$10.35 in 1993 to $9.07 in 1994.

     Net Interest Income

     Interest income was virtually unchanged year to year ($5,089,614 in 1994
vs. $5,074,323 in 1993), with a decrease of income from interest-bearing
deposits held by the bank in other institutions being offset by an increase in
income from federal funds sold. The latter are instruments sold to other banks
to meet short-term liquidity needs.

     Interest on loans grew only 1.15% year to year, with growth occurring
primarily in the real estate loan area. The return on average earning assets
dropped from 7.74% in 1993 to 7.68% in 1994, as the general decline in interest
rates from 1993 levels was the primary driver of these lower asset yields.

     The Bank's net interest margin (i.e., the difference between the cost of
funds for the bank and the cost at which it can lend these funds) remained the
same in 1994 as in 1993 at 4.51%. Management anticipates a decline in net
interest margins in 1995 if short-term interest rates continue to rise.

     Interest Expense

     Interest expense remained practically unchanged year to year, although
deposits decreased by approximately $2.5 million year to year. The effects of
the Federal Reserve's interest rate policy began to have a greater effect during
the later part of 1994, reflecting an increased cost of funds which is expected
to continue into 1995. An increase in the bank's cost of funds is also likely
because the bank must compete against various bank and non-bank institutions to
retain or expand its deposit base.

     Provision for Loan Losses

     Non-performing assets as a percentage of total assets remained at
comparable levels year to year.

     Shawnee's allowance for loan losses was $184,000 at the end of 1994 and
represented .48% of loans. The allowance at the end of 1993 was $184,000, or
 .47% of loans. Total risk elements, which include nonperforming assets and loans
90 days past due, decreased from .58% of loans at the end of 1993 to .52% of
loans at December 31, 1994.

     Shawnee's 1994 provision was consistent with the volume of net charge-offs
and responsive to overall asset quality trends, and the allowance for loan
losses is maintained at a level which, in management's judgment, is adequate to
absorb potential losses in its loan portfolio.
    
     The breakdown of the categories for loan loss reserves were as follows for
both 1994 and 1993:

          Real Estate Loans        $ 30,000
          Installment Loans        $ 40,000
          Commercial Loans         $114,000

     Other than as disclosed in this Management's Discussion and Analysis or
elsewhere in this Proxy Statement/Prospectus, Shawnee management is unaware of
any potential problem loans. Further, the Bank does not make any foreign loans,
nor is it aware of any significant concentration of loans.
     
     Non-Interest Income

     Other income, which includes revenues from service fees, was also flat year
to year ($144,766 in 1994 vs. $158,043 in 1993). Gains on the sales of
securities in 1993 matched increases in service fees and other revenues in 1994.

                                      -29-
<PAGE>
 
     Non-Interest Expense

     Other expenses, which includes salaries, employee benefits and expenses
related to the maintenance and upkeep of the bank's properties, rose 7.9% year
to year. Salary expense increased as a result of increased staff levels added
during the year. In addition, increased occupancy expense, insurance expense and
expenses related to the continuing phase-in of several automated teller machines
("ATMs") affected costs significantly. While expenses relating to operation of
ATMs currently exceed revenues, management believes that the attractiveness to
customers of ATMs makes them worthwhile, and that this imbalance will equalize
over time.

     Book Value and Dividends

     Book value continued its historic climb to $94.55 in 1994 from $91.11 in
1993. This occurred notwithstanding the implementation of SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," which
negatively impacted shareholders' equity by $235,119, or $2.93 per share. As
required by SFAS No. 115, implemented on January 1, 1994, management classified
its entire securities portfolio as available for sale due to the identification
of circumstances which could result in the securities not being held to
maturity.

     In 1994 Shawnee raised its dividend to $2.70 per share from $2.60 per share
in 1993, continuing its historical pattern of increasing annual dividends.

     Other Key Indices
    
     As of December 31, 1994, the average yields on the Bank's interest
generating assets were as follows:

           Loans                        8.82%
           Investments                  6.38%
           Interest-bearing deposits    4.11%
           Federal Funds                4.21%

     The average cost for customers' deposits was 3.59%.

     Return on average assets (ROA) and return on average equity (ROE) were
1.01% and 9.69%, respectively, for 1994 versus 1.18% and 12.28% for 1993. These
ratios indicate to shareholders how well their money is being employed by
Shawnee and compare favorably with other banks of similar size. The declines in
ROA and ROE were largly due to the decrease in earnings year to year. The
decline in ROE was proportionately greater than that of ROA because the capital
base of Shawnee continued to increase given the Bank's overall profitability,
while the Bank's asset size fell slightly.
     
     Capital Resources
    
     The Bank is required to maintain certain levels of capital in accordance
with regulations of the FDIC.  The minimum guidelines for the ratio of total
capital to risk-weighted assets (including certain off-balance-sheet
activities, such as standby letters of credit) is 8%.  At least 4% of the
total capital must be "Tier I Capital" or core capital, which may be composed
of common equity, retained earnings and a limited amount of perpetual
preferred stock, less goodwill and intangible assets other than purchased
mortgage servicing rights acquired after February 18, 1992.  The remainder may
consist of subordinated debt, cumulative preferred stock and a limited amount
of loan loss reserves ("Tier II Capital").  In addition, the Federal Reserve
Board has established minimum leverage ratio guidelines for bank holding
companies.  These guidelines provide a minimum leverage ratio of tangible
equity (shareholders' equity less disallowed intangibles) to adjusted average
quarterly assets equal to 3% for bank holding companies that meet certain
specified criteria.  The Bank's capital levels and capital requirements as of
December 31, 1994, are set forth in the following table:

1993 versus 1992

     Net Income

     Net income in 1993 reached an historic high as a result of a very favorable
net interest margin (i.e., the difference between the cost of funds for the Bank
and the cost at which it can lend these funds). This was coupled with a stronger
economy in 1993 than in 1992 and lower interest rates, causing business and
individuals to increase their demand for loans. On a year-to-year basis, net
income increased almost 15% from $728,484 in 1992 to $834,494 in 1993, and net
income per share increased from $9.01 to $10.35.

     Net Interest Income

     Lending increased substantially in 1993. In particular, lending in the
mortgage, installment and commercial sectors was up approximately 25% year to
year. This resulted in interest income from loans increasing $148,244 or 4.5%.
This was partially offset by less income from the Bank's holdings of investment
securities, as interest rates declined over the course of the year.

     Interest Expense

     Interest expense declined to $2,038,678 (7.31%) from 1992 to 1993,
notwithstanding an increase in deposits of approximately $3.2 million year to
year. This decrease was a result of the Federal Reserve Board's move to lower
interest rates through most of 1993, thereby decreasing the interest the Bank
was required to pay on depositor's accounts. The Bank's net interest margin
decreased from 4.72% to 4.51% year to year.

     Provision for Loan Losses

     Shawnee's allowance for loan losses fell slightly from 1992 to 1993 from
$195,788 to $184,118. This reflected an improvement in the economy but remained
at a level that management believed was adequate to absorb possible losses on
loans that may become uncollectible.

     Non-Interest Income

     Other income increased significantly year to year ($158,053 vs. $69,452).
Increased service fee income and gains from the sale of investment securities
accounted for the bulk of the difference year to year.

     Non-Interest Expense

     Other expenses increased 6.3% from 1992. Salary expense increased
significantly as a result of a raise effected during the year and an increase in
staff levels. In addition, certain other expenses increased as a result of costs
related to the expansion to a branch office in Loysburg, Pennsylvania (and
related depreciation increase) and the addition of three drive-up ATMs and one
interior ATM. Also, a change in accounting principle, SFAS 109 (Accounting for
Income Taxes) resulted in a deferred benefit of $24,621 in 1993.

     Book Value and Dividends

     Given the increase in net income of 15% year to year, book value per share
increased to $91.11 in 1993 from $83.09 in 1992, a boost of 9.65% year to year.
Shawnee also increased its dividend from $2.50 to $2.60.

     Other Key Indices
    
     Other measures of overall performance, including return on assets and
return on equity, also improved from 1992 to 1993, from 1.16% to 1.18%, and from
11.83% to 12.28%, respectively.
     
Interest Rate Sensitivity and Liquidity

     The objective of the Corporation's asset/liability management policy is to
maximize current and future net interest income within acceptable levels of
interest rate risk while satisfying liquidity and capital requirements.
Consistent with conservative banking practices, the Asset/Liability Management
Committee recommends the allocation of funds within prescribed guidelines to
achieve specified target goals for Return on Equity and Return on Assets. These
guidelines are established to reduce the bank's level of risk to fluctuating
interest rates, while leaving open the possibility of capitalizing on favorable
trends.

</TABLE>

     As measured by the one-year cumulative sensitivity gap at December 31,
1994, the Corporation was liability sensitive such that the maturity and
repricing of interest bearing liabilities exceeded interest earning assets. As
discussed elsewhere in this Management's Discussion and Analysis, short-term
market interest rates rose dramatically in 1994 as a result of the Federal
Reserve's efforts to slow the economy by raising the federal funds rate. Long-
term rates have also risen but not to the same extent as short-term rates.
Management expects these rate increases to continue into 1995. The focus in 1994
was to reduce the Corporation's sensitivity to rising interest

                                      -34-
<PAGE>
 
rates to the extent possible while limiting the negative impact on earnings.
Measures in 1994 to reduce the liability-sensitive position included adjusting
lending rates upward to reflect the increased costs on deposits, subject to
competitive factors, as well as increasing investments in higher-yielding,
longer-term government agency investments (many of which remain subject to calls
prior to maturity).

     On a quarterly basis, or as may be necessitated by significant changes in
the marketplace, the Committee reviews its asset/liability management policy.
Factors considered by the Committee in evaluating interest rate risk include,
but are not limited to, the current interest rate outlook nationally and
locally, current forecasts on loans and deposits, various rate-sensitive asset-
to-liabilities ratios, and current and projected liquidity needs.

     Shawnee manages its liquidity position by continually evaluating its
funding needs and the cost and terms of funding sources. The Corporation has
sufficient sources of funds available to meet its routine operational cash needs
by virtue of its monetary assets and liabilities. The Corporation does not
borrow to meet its long-term liquidity needs.

     Net cash from operating activities in 1994 was provided by net income,
increased by non-cash related items such as depreciation expense. Net cash from
investing activities was primarily redeployed in the purchase of investment
securities. Interest bearing accounts were decreased to offset an approximate
$2.5 million decline in customer deposits. Federal funds sold and repayments on
loans provide sources of short-term liquidity. In addition, the Corporation's
securities portfolio provides liquidity due to the active markets for the
securities held.

        Net Income

        Net income decreased marginally quarter to quarter by .98% from $194,000
  in 1994 to $191,000 in 1995.  The principal reason for this decline was a
  higher overall level of interest paid on deposits. Net income per share
  slipped from $2.42 to $2.38.

        Net Interest Income

        Interest income increased 2% quarter to quarter from $1,238,000 in 1994
  to $1,263,000 in 1995.  Interest earned from federal funds sold increased
  significantly on higher volumes, offset partially by a decrease on investment
  securities income.  This reflected the bank's overall move toward lessening
  the maturities of its investments in light of a trend of increasing interest
  rate moves by the Federal Reserve Board.  Interest income from loans was flat
  quarter to quarter ($839,000 in 1994 versus $841,000 in 1995) with the overall
  level of loans remaining fairly constant quarter to quarter as well.

        The return on average earning assets decreased slightly from 1.13% to
  1.12% from 1994 to 1995. The increase in interest expense accounted for the
  change.

        The bank's net interest margin (i.e., the difference between the cost of
  funds for the bank and the cost at which it can lend these funds) increased in
  1995 as compared to 1994, 4.40% versus 4.35%. The principal factor causing the
  increase in net interest margin was an overall rise in the level of non-
  interest-bearing deposits during the first quarter of 1995.

        Interest Expense

        Interest expense on deposits increased significantly year to year from
  $507,000 in 1994 to $542,000 in 1995, or 6.9%.  The increase in the expense
  was due primarily to the increase in short-term interest rates during the
  period.  In addition, competitive pressures in the bank's market area required
  it to offer higher yields to maintain its deposit base at prior levels.

        Provision for Loan Losses

        Nonperforming loans as a percentage of total average assets remained
  approximately the same quarter to quarter (.238% versus .235%).  Shawnee did
  not increase its allowance for loan losses during the first quarter of 1995
  and did not experience any increase in nonperforming loans during the period.
  Total risk elements, which include nonperforming assets and loans 90 days past
  due, decreased from .77% of loans in 1994 to .69% of loans in 1995.

        The Bank's provision for loan losses continued to be consistent with the
  volume of net charge-offs and responsive to overall asset quality trends.  The
  provision is maintained at a level which management believes to be adequate to
  absorb potential losses in its portfolio.

        Non-Interest Income

        Other income was flat quarter to quarter ($40,000 in 1995 versus $42,000
  in 1994).  A slight decrease in service fee income was offset by a small
  increase in other income.

        Non-Interest Expense

        The overall level of non-interest expenses necessary for the operation
  of the bank remained constant quarter to quarter ($509,000 in 1995 versus
  $507,000 in 1994).  Salaries and benefits decreased slightly by 3.1%.  Other
  expenses, which included an increase in the cost of FDIC insurance, increased
  by 6.1%.

        Book Value and Dividends

        Book value per share increased significantly during the first quarter of
  1995 to $100.43 per share from $94.55 at the end of 1994.  The increase was
  due to the continued profitability of the bank ($2.38 per share during the
  quarter) as well as a turnaround in the value of the securities portfolio held
  by the bank from a net unrealizable holding loss of $235,000 at the end of
  1994 to a net unrealized holding gain of $46,000 at the end of the first
     
                                      -37-

  quarter of 1995.  The bank holds these securities as "available for sale" but
  has no present intention of liquidating these securities.

        Shawnee paid a dividend of $2.45 per share in January, 1995.  Shawnee
  has historically paid its second, and larger, dividend in January of each
  year.  Pursuant to the Plan of Merger, Shawnee is permitted to pay an
  additional dividend in 1995 based on a pro-ration of $2.70 per share divided
  by the number of months until the merger is consummated.  Shawnee anticipates
  paying a dividend of $1.35 per share at the end of June.

        Other Key Indices

        Return on average assets (ROA) and return on average equity (ROE) were
  1.12% and 10.60% for the first quarter of 1995.  These ratios indicate to
  shareholders how well Shawnee is employing the bank's assets to create income
  and how well the bank is employing shareholders' equity to create income.  ROA
  decreased slightly quarter to quarter (1.13% vs 1.12%) due to slightly lower
  levels of income on a marginally higher asset base, and ROE declined from
  11.55% to 10.60% due primarily to higher overall levels of shareholders'
  equity because of the turnaround in the value of the securities portfolio.

        Liquidity

        On a quarterly basis, or as may be necessitated by significant changes
  in the marketplace, the bank, through its Asset and Liability Committee
  ("ALCO") reviews its asset/liability management policy. During the first
  quarter the bank increased loan rates including mortgage rates, in particular,
  to reflect changes in the overall market and increased the rates paid on
  deposits to maintain its deposit base and counter competitive pressures.

        Shawnee manages its liquidity position by continually evaluating its
  funding needs and the cost and terms of funding sources.

        Net cash from operating activities during the first quarter was provided
  by net income, increased by non-cash related items such as depreciation
  expense, for a net overall increase of $250,000.

        Net cash flows from investing activities during the quarter, including
  proceeds from the maturities of investment securities, were primarily
  redeployed by purchasing additional investment securities.  The bank was also
  able to marginally increase loans during the quarter, reversing a decline in
  lending of $352,000 during the fourth quarter of 1994.  Areas of lending which
  increased included student loans and commercial loans.  Overall, net cash
  provided by investing activities increased by $247,000 during the quarter.

        The net level of deposits increased by $795,000 during the first
  quarter.  This was primarily due to the bank's increase in demand deposits of
  12.8%.  Cash flows were decreased by the payment of a dividend in the first
  quarter.

        Overall, net cash and cash equivalents increased by $1,277,000 during
  the quarter.  In addition, federal funds sold, and repayments on loans provide
  sources of short-term liquidity.   Further, Shawnee's securities portfolio
  provides liquidity due to the active markets for the securities held.
     

  MARKET AND DIVIDEND INFORMATION CONCERNING SHAWNEE COMMON STOCK

        There has never been an organized public trading market for Shawnee
  Common Stock.  Shawnee Common Stock is traded occasionally in the over-the-
  counter market.  At the present time, there are no securities dealers which
  make a market for Shawnee Common Stock, and NASDAQ does not report prices for
  trades of Shawnee Common Stock.  While Shawnee's management from time to time
  receives information concerning trades of Shawnee Common Stock, it does not
  have any reliable basis on which to provide information concerning trades of
  Shawnee Common Stock, and it does not have any reliable basis on which to
  provide information concerning

                                      -38-

  historical ranges of trading prices or bid-and-asked quotations.  On January
  4, 1995, prior to the announcement of the Shawnee Merger, 300 shares of
  Shawnee Common Stock were traded by parties not affiliated with Shawnee at a
  price of $92 per share.  Because of the limited trading in Shawnee Common
  Stock, this price should not necessarily be considered as indicative of
  Shawnee Common Stock's true market value.

        For 1994, Shawnee declared an annual dividend of $2.70 per share.  For
  1993, the annual dividend was $2.60 per share.  Under the terms of the Plan of
  Merger, Shawnee is permitted to pay prior to the effective date of the Merger
  a prorated dividend for 1995 based on the annual rate of $2.70 per share.  The
  amount of this dividend will depend upon the timing of the merger and of the
  record date for the first Keystone dividend following the Merger.

        While banking laws and regulations limit the amount of dividends that
  may be paid by Shawnee, these laws and regulations would not currently
  restrict the payment by Shawnee of dividends at Shawnee's historical rates.


                              BUSINESS OF SHAWNEE

  History and Business

        The Everett Bank was incorporated on December 21, 1949 as a Pennsylvania
  banking institution. In 1986, the shareholders of The Everett Bank approved a
  reorganization into a holding company structure, whereby The Everett Bank
  became the sole subsidiary of the newly-created Shawnee Financial Services
  Corporation ("Shawnee").  Shawnee's headquarters are located at 115 East Main
  Street, Everett, Pennsylvania 15537, a two-story building in downtown Everett
  which contains a full service banking facility and the central administration
  offices of Shawnee.

        Shawnee, through its sole subsidiary, The Everett Bank, transacts
  business with customers primarily within its local trade area, which is
  concentrated in Bedford County, Pennsylvania.  Shawnee engages in a full-
  service commercial banking business within the vicinity of its service area.
  It offers various loan services, including secured and non-secured commercial
  and consumer loans, construction and mortgage loans, all types of deposit
  services, including check services, and interest-bearing demand, savings and
  other time deposits.  Shawnee's business is not seasonal in nature, but does
  vary with the business cycle.  In addition, as a community bank, Shawnee's
  profitability is impacted by the commercial activity in Bedford County.
    
        As of March 31, 1995, The Everett Bank had total assets of approximately
  $71,209,000, total shareholders' equity of approximately $8,053,000, and total
  deposits and liabilities of approximately $62,627,000.
     
        Major classifications of loans are summarized as follows:

        In addition to its main office in Everett, the Bank has three branch
  offices located in Bedford, Breezewood and Loysburg, Pennsylvania.  All of
  these facilities are owned by Shawnee.  Management believes all such

                                      -39-
<PAGE>
 
  facilities are in good repair and well suited to their current uses.  The
  Northern Bedford County branch office in Loysburg was significantly updated
  and expanded in 1993.

        In the past two years, the Bank added four automated teller machines
  ("ATMs") to various locations.  These machines permit customers to conduct
  routine banking transactions 24 hours a day, and all but one are located on
  the premises of a banking office.  All the ATMs are part of the MAC Network,
  which consists of over 14,000 ATMs owned by numerous banks and savings and
  loans in over 16 states.

        As of December 31, 1994, the Bank had 38 full-time employees and seven
  part-time employees. The Bank believes its relationship with its employees to
  be good.

  Competition

        The Everett Bank competes actively with other commercial banks and
  savings and loans in its area, many of which are larger than The Everett Bank,
  as well as with major banking and financial institutions headquartered
  elsewhere.  The Everett Bank is generally competitive with all competing
  financial institutions in its service area with respect to interest rates paid
  on time and savings deposits, service charges on deposit accounts and interest
  rates charged on loans.  Recently, a number of competitors have begun to offer
  enhanced financial services and products, including mutual funds, to their
  customers which The Everett Bank does not offer.

  Regulation and Supervision

        Shawnee is a bank holding company, registered as such with the Federal
  Reserve Board under the Bank Holding Company Act of 1956.  As a bank holding
  company, Shawnee is required to file with the Federal Reserve Board an annual
  report and other information.  The Federal Reserve Board is also empowered to
  make examinations and inspections of Shawnee and its subsidiary.

        In addition, The Everett Bank is subject to the supervision of and is
  regularly examined by the Pennsylvania Department of Banking and the Federal
  Deposit Insurance Corporation ("FDIC"), and is subject to certain regulations
  of the Federal Reserve Board.  The areas of operation of The Everett Bank
  which are subject to regulation by federal and Pennsylvania laws, regulations
  and regulatory agencies include reserves against deposits, maximum interest
  rates for specific classes of loans, truth-in-lending and truth-in-savings
  disclosure, permissible types of loans and investments, mergers and
  acquisitions, issuance of securities, payment of dividends, Community
  Reinvestment Act evaluations, establishment of branches and other aspects of
  operations.

        Shawnee is not a reporting company under the Exchange Act and is
  therefore not required to file reports with the Securities and Exchange
  Commission.  Shawnee has regularly provided its shareholders with an Annual
  Report which has included audited financial statements.

         COMPARISON OF KEYSTONE COMMON STOCK AND SHAWNEE COMMON STOCK

  General
    
        Upon consummation of the Merger, shareholders of Shawnee will become
  shareholders of Keystone.  Since the Articles of Incorporation ("Articles")
  and By-Laws of Keystone and Shawnee are not the same, the Merger will result
  in certain changes in the rights of the holders of Shawnee Common Stock.  The
  material differences in the rights of holders of Keystone Common Stock and
  Shawnee Common Stock are discussed below.
     

  Voting Rights

        General.  The holders of Keystone Common Stock, like the holders of
  Shawnee 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
  Shawnee 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.

        Shawnee's Articles require that certain transactions involving Shawnee
  be approved by the vote of the holders of at least 75% of the outstanding
  shares of Shawnee Common Stock.  The transactions subject to Shawnee's special
  voting requirements are a merger, consolidation, liquidation or dissolution of
  Shawnee or any action that would result in the sale or other disposition of
  all or substantially all of the assets of Shawnee.

                                      -44-

  Board of Directors

        Classified Boards.  The Articles of Keystone and the By-Laws of Shawnee
  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.

        Shawnee's By-Laws provide that Shawnee's Board of Directors shall
  consist of not less than six nor more than 25 directors, and that within those
  limits the Board may fix the number of directors.  Vacancies on the Shawnee
  Board, including vacancies resulting from an increase in the number of
  directors, may be filled by a majority vote of the remaining directors (though
  less than a quorum).  Directors elected by the Board to fill vacancies serve
  for the remainder of the term of the class to which they have been elected.
  The shareholders of Shawnee can also change the number of Shawnee directors by
  amending the By-Laws 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.

        Shawnee's Articles and By-Laws are silent as to removal of directors by
  shareholder vote.  Under the Pennsylvania Business Corporation Law ("BCL"),
  because Shawnee has a 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 Shawnee 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 Shawnee Common Stock.

        Nomination of Director Candidates.  The Articles of Keystone and the By-
  Laws of Shawnee 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.  Shawnee's By-Laws require the
  notice to be given not less than 60 days prior to the meeting at which the
  election is to be held.


  Amendment of Articles and By-Laws

        Proposal of amendments.  Because Shawnee does not have a class of
  securities registered under the Exchange Act, the BCL provides that amendments
  to Shawnee's Articles may be proposed either (1) by the Board of Directors or
  (2) by a petition of the holders of not less than 10% of the outstanding
  Shawnee Common Stock.  Under the BCL, because Keystone's Common Stock is
  registered under the Exchange Act, the shareholders of Keystone are not
  entitled by statute to propose amendments to Keystone's Articles.  Any
  amendment to Keystone's Articles must first be proposed by Keystone's Board of
  Directors.  Any shareholder of Shawnee or Keystone may propose an amendment to
  the corporation's By-Laws.

        Approval of Amendments.  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

                                      -45-
<PAGE>
 
  beneficially owned by an interested shareholder to approve any amendment to
  Keystone's Articles or By-Laws.  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.  Under applicable provisions of the BCL, such amendments may
  be adopted by a majority of the votes cast at a meeting of Keystone
  shareholders.  Except as to matters for which a shareholder vote is required
  by statute, Keystone's Board may also amend the By-Laws without shareholder
  approval by a vote including a majority of the disinterested directors then in
  office.

        Shawnee's Articles require the vote of the holders of at least 75% of
  the outstanding Shawnee Common Stock to approve any amendment of the special
  shareholder vote provisions described above under "Voting Rights--Special
  Votes for Certain Transactions."  Under applicable provisions of the BCL,
  amendments to other provisions of Shawnee's Articles may be approved by a
  majority of the votes cast at a meeting of Shawnee shareholders.

        Shawnee's By-Laws require the vote of the holders of at least 75% of the
  outstanding Shawnee Common Stock to adopt any amendment to the By-Laws of
  Shawnee.  Except as to matters for which a shareholder vote is required by
  statute, Shawnee's Board may also amend the By-Laws without shareholder
  approval by a majority vote of the members of the Board.


  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 eight one-thousandths (8/1,000ths)
  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 eight
  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 eight 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 tradeable.

        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

                                      -46-
<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
  eight 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.

        Prior to the Distribution Date, the terms of the Rights may be amended
  by the Board of Directors in any respect whatever, without the consent of the
  holders of the Rights, 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 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.  Because it does not have a class of securities registered
  under the Exchange Act, Shawnee is not subject to these provisions.

        Under Section 2538 of the BCL, any merger, consolidation, share exchange
  or sale of assets between Keystone or a subsidiary and any Keystone
  shareholder, any division of Keystone in which any Keystone 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 Keystone 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 Keystone 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 Keystone's 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 which acquires voting power over Keystone shares representing 20% or
  more of the votes which all Keystone shareholders would be entitled to cast in
  an election of directors, any other Keystone 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 Keystone shares representing 20% or more of the voting
  power in an election of Keystone

                                      -47-
<PAGE>
 
  directors unless (1) the business combination or the acquisition of the 20%
  interest is approved by Keystone's Board of Directors 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.


  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.  Neither the
  Keystone nor Shawnee Common Stock is listed on a national securities exchange.
  However, Keystone currently has more than 2,000 shareholders of record, and
  Shawnee currently has fewer than 2,000 shareholders of record.  Shareholders
  of Shawnee will have the right to dissent from the Merger.  See "Plan of
  Merger--Dissenters' Rights of Shawnee Shareholders."


  Preferred Stock

        Shawnee's Articles do not authorize any class of stock other than
  Shawnee 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 Shawnee 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

                                      -48-
<PAGE>
 
  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 Shawnee,
  whether voluntary or involuntary, the holders of Keystone or Shawnee 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 Shawnee Common
  Stock.  Holders of fully paid shares of Keystone or Shawnee Common Stock are
  not subject to any liability for further calls or assessments.


                                LEGAL OPINIONS

          Opinions with respect to certain legal matters in connection with the
  Merger will be rendered by Reed Smith Shaw & McClay, Pittsburgh, Pennsylvania,
  as counsel for Keystone, and by Buchanan Ingersoll Professional Corporation,
  Pittsburgh, Pennsylvania, as counsel for Shawnee.

                         INDEPENDENT AUDITORS' REPORT



  To the Board of Directors
  Shawnee Financial Services Corporation
  Everett, Pennsylvania


  We have audited the accompanying consolidated balance sheets of Shawnee
  Financial Services Corporation and Subsidiary, as of December 31, 1994 and
  1993, and the related consolidated statements of income, changes in
  stockholders' equity and cash flows for the years ended December 31, 1994,
  1993 and 1992.  These financial statements are the responsibility of the
  Corporation's management.  Our responsibility is to express an opinion on
  these financial statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
  standards.  Those standards require that we plan and perform the audit to
  obtain reasonable assurance about whether the financial statements are free of
  material misstatement.  An audit includes examining, on a test basis, evidence
  supporting the amounts and disclosures in the financial statements.  An audit
  also includes assessing the accounting principles used and significant
  estimates made by management, as well as evaluating the overall financial
  statement presentation.  We believe that our audits provide a reasonable basis
  for our opinion.

  In our opinion, the consolidated financial statements referred to above
  present fairly, in all material respects, the financial position of Shawnee
  Financial Services Corporation and Subsidiary, as of December 31, 1994 and
  1993, and the results of its operations and its cash flows for the years ended
  December 31, 1994, 1993 and 1992 in conformity with generally accepted
  accounting principles.

  As discussed in Note A to the financial statements, the Bank changed its
  method of accounting for investment securities by adopting Financial
  Accounting Standards Board No. 115 "Accounting for Certain Investments in Debt
  and Equity Securities."

  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
  SHAWNEE FINANCIAL SERVICES CORPORATION



  NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Principles of Consolidation:  The consolidated financial statements include
  the accounts of Shawnee Financial Services Corporation and its wholly-owned
  subsidiary, The Everett Bank.  All significant intercompany accounts have been
  eliminated in the consolidation.

  Investment Securities:  In May 1993, the Financial Accounting Standards Board
  (the FASB) issued Statement of Financial Accounting Standards No. 115,
  "Accounting for Certain Investments in Debt and Equity Securities."  Statement
  No. 115 requires all investments in debt and equity securities to be
  classified into three categories.  Securities which management has positive
  intent and ability to hold until maturity are classified as held to maturity.
  Securities held to maturity are stated at cost, adjusted for amortization of
  premium and accretion of discount, computed primarily under the interest
  method.  Securities that are bought and held principally for the purpose of
  selling them in the near term are classified as trading securities. All other
  securities are classified as available for sale securities.  Unrealized
  holding gains and losses for trading securities are included in earnings.
  Unrealized gains and losses for available for sale securities are excluded
  from earnings and reported as a net amount and separate component of
  stockholders' equity until realized.

  As required by Statement No. 115, management implemented the standard on
  January 1, 1994 and classified its entire securities portfolio as available
  for sale due to the identification of circumstances which could result in the
  securities not being held to maturity.  Circumstances resulting in securities
  sales could include, but are not limited to, changes in market interest rates,
  changes in prepayment risk, income tax considerations, and liquidity needs.
  At this time, management has no intention of establishing a trading securities
  classification.

  Interest and dividends on securities are reported as interest income.  Gains
  and losses realized on sales of securities represent the differences between
  net proceeds and carrying values determined by the specific identification
  method.

  Loans and Allowance for Loan Losses:  Loans are stated at unpaid principal
  balances, less the allowance for loan losses and net unearned discounts.

  Unearned discounts on installment loans are recognized as income over the term
  of the loans using a method that approximates the interest method.

  Loans are placed on nonaccrual when a loan is specifically determined to be
  impaired.  Any unpaid interest previously accrued on those loans is reversed
  from income.  Interest income generally is not recognized on specific impaired
  loans unless the likelihood of further loss is remote.  Interest payments
  received on such loans are applied as a reduction of the loan principal
  balance.  Interest income on other nonaccrual loans is recognized only to the
  extent of interest payments received.

  The allowance for loan losses is maintained at a level which, in management's
  judgement, is adequate to absorb potential losses inherent in the loan
  portfolio.  The amount of the allowance is based on management's evaluation of
  the collectibilty of the loan portfolio, including the nature of the
  portfolio, credit concentrations, trends in historical loss experience,
  specific impaired loans, and economic conditions.  Allowances for impaired
  loans generally are determined based on collateral values or the present value
  of estimated cash flows.  The allowance is increased by a provision for loan
  losses, which is charged to expense, and reduced by charge-offs, net of
  recoveries.  Changes in the allowance relating to impaired loans are charged
  or credited to the provision for loan losses.

  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
  SHAWNEE FINANCIAL SERVICES CORPORATION



  NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

  Premises and Equipment:  Premises and equipment are stated at cost less
  accumulated depreciation. Depreciation is computed on the straight-line method
  and accelerated methods over the estimated useful lives of the assets ranging
  from 3 to 40 years.  Expenditures for maintenance and repairs are charged to
  expense as incurred.  Cost of major additions or improvements are capitalized.
  When premises and equipment are removed or otherwise disposed of, the cost and
  related accumulated depreciation are removed from the accounts, and any
  resulting gain or loss is credited or charged to income.

  Income Taxes:  In February 1992, the FASB issued Statement of Financial
  Accounting Standards No. 109, "Accounting for Income Taxes."  Statement No.
  109 requires a change from the deferred method of accounting for income taxes
  of APB Opinion 11 to the asset and liability method of accounting for income
  taxes.  Under the asset and liability method of Statement No. 109, deferred
  tax assets and liabilities are recognized for the future tax consequences
  attributable to differences between the financial statement carrying amounts
  of existing assets and liabilities and their respective tax bases.  Deferred
  tax assets and liabilities are measured using enacted tax rates expected to
  apply to taxable income in the years in which those temporary differences are
  expected to be recovered or settled.  Under Statement No. 109, the effect on
  deferred tax assets and liabilities of a change in tax rates is recognized in
  income in the period that includes the enactment date.

  Effective January 1, 1993, management adopted Statement No. 109 and reported
  the cumulative effect of that change in the method of accounting for income
  taxes in the accompanying 1993 statement of income.

  Earnings Per Share:  Earnings per share are calculated on the basis of the
  weighted average number of common shares outstanding.

  Cash Flow Information:  For purposes of the Statements of Cash Flows, cash and
  cash equivalents are defined as those amounts included in the balance sheet
  captions Cash and due from banks and Federal funds sold.

  Cash payments for interest in 1994, 1993 and 1992 were $2,185,657, $1,997,160
  and $2,079,466, respectively.  Cash payments for income taxes for 1994, 1993
  and 1992 were $339,249, $281,575 and $145,549, respectively.

  Reclassifications:  Certain amounts in 1993 and 1992 have been reclassified to
  conform with the 1994 presentation.

  The Bank's primary business activity is with customers located within its
  local trade area which is concentrated in Bedford County,  Pennsylvania.
  Commercial, residential and personal loans are granted.  Although the loan
  portfolio is diversified, loans outstanding to individuals and businesses are
  dependent upon local economic conditions in the immediate trade area.

  Loans on which the accrual of interest has been discontinued amounted to
  $170,600 at December 31, 1994 and 1993.  The gross amount of interest which
  would have been recorded if all such loans had been accruing interest at their
  original terms from the date of being placed on nonaccrual is $53,399 for 1994
  and $37,949 for 1993.

  NOTE F - PENSION PLANS

  The Bank has a non-contributory defined benefit pension plan covering
  substantially all employees meeting minimum age and service requirements.  The
  plan generally provides benefits based on years of credited service and final
  average earnings.  The current funding policy is to contribute annually the
  maximum amount that can be deducted for federal income tax purposes.  Pension
  plan assets are primarily mortgage-backed securities. Changes in plan assets
  values attributable to differences between actual and expected returns on plan
  assets are deferred as unrecognized gains or losses and included in the
  determination of the pension cost over time.

  Net pension expense for 1994, 1993 and 1992 consisted of the following:

  The projected benefit obligation was determined using an assumed discount rate
  of 7.5% for 1994 and 1993 and 5.5% for 1992.  The expected rate of increase in
  compensation was 5.5% for each year and the assumed rate of return on plan
  investment earnings was 7.5% for 1994 and 1993 and 8.0% for 1992.

  The Bank maintains a profit sharing plan covering substantially all employees.
  Contributions to the plan are at the discretion of the Board of Directors.
  Amounts charged to operations during 1994, 1993 and 1992 were $0, $30,792 and
  $48,025, respectively.

  NOTE G - COMMITMENTS AND CONTINGENCIES

  In the normal course of business, there are various outstanding commitments
  and certain contingent liabilities which are not reflected in the accompanying
  financial statements.  These commitments and contingent liabilities represent
  financial instruments with off-balance-sheet risk.  The contract or notional
  amounts of those instruments were comprised of commitments to extend credit
  approximating $912,700 and $1,780,000 as of December 31, 1994 and 1993,
  respectively.

  The instruments involve, to varying degrees, elements of credit and interest
  rate risk in excess of the amount recognized in the balance sheet.  The same
  credit policies are used in making commitments and conditional obligations as
  for on-balance-sheet instruments.  The amount of collateral obtained, if
  deemed necessary upon extension of credit, is based on management's credit
  evaluation.  The terms are typically for a one year period, with an annual
  renewal option subject to prior approval by management.

  NOTE G - COMMITMENTS AND CONTINGENCIES (CONTINUED)

  Commitments to extend credit are agreements to lend to a customer as long as
  there is no violation of any condition established in the loan agreement.
  These commitments are comprised primarily of available commercial and personal
  lines of credit.

  The exposure to loss under these commitments is limited by subjecting them to
  credit approval and monitoring procedures.  Substantially all of the
  commitments to extend credit are contingent upon customers maintaining
  specific credit standards at the time of the loan funding.  Management
  assesses the credit risk associated with certain commitments to extend credit
  in determining the level of the allowance for loan loses. Since some of the
  commitments are expected to expire without being drawn upon, the total
  contractual amounts do not necessarily represent future funding requirements.

  The Bank is involved in various legal actions from normal business activities.
  Management believes that the liability, if any, arising from such actions will
  not have a material adverse effect on the Bank's financial position.


  NOTE H - RECENT ACCOUNTING PRONOUNCEMENTS

  During 1992, the FASB issued Statement No. 107 "Disclosures about Fair Value
  of Financial Instruments" which is effective for fiscal years ending after
  December 15, 1992, except for entities with less than $150 million in total
  assets.  For those entities, the effective date is for fiscal years ending
  after December 15, 1995. Statement No. 107 requires disclosure of the fair
  value of financial instruments, both assets and liabilities recognized and not
  recognized in the financial statements, with exceptions for certain financial
  instruments.

  In May 1993, the FASB issued Statement No. 114 "Accounting by Creditors for
  Impairment of a Loan" which is effective for fiscal years beginning after
  December 15, 1994.  Statement No. 114 addresses the methods to be used by a
  creditor to measure the impairment of a loan and the proper recognition of a
  change in the value of an impaired loan.

  In October 1994,  the FASB issued Statement No. 118 "Accounting by Creditors
  for Impairment of a Loan--Income Recognition and Disclosure" which amends
  Statement No. 114 by allowing creditors to use existing methods for
  recognizing interest income on impaired loans.  Statement No. 118 is effective
  concurrent with the effective date of Statement No. 114.

  In October 1994, the FASB issued Statement No. 119 "Disclosure About
  Derivative Financial Instruments and Fair Value of Financial Instruments"
  which is effective for calendar year 1994 financial statements, except for
  entities with less than $150 million in total assets having a one year delay.
  Statement No. 119 primarily requires disclosures about the amounts, nature and
  terms of derivatives that do not fall under FASB's Statement No. 105
  "Disclosures of Information about Financial Instruments with Off-Balance Sheet
  Risk and Financial Instruments with Concentrations of Credit Risk."

  Management is currently evaluating the combined financial statement impact of
  these statements.

  NOTE D - INVESTMENT SECURITIES

  In May 1993, the Financial Accounting Standards Board (the FASB) issued
  Statement of Financial Accounting Standards No. 115, "Accounting for Certain
  Investments in Debt and Equity Securities." Statement No. 115 requires all
  investments in debt and equity securities to be classified into three
  categories. Securities which management has positive intent and ability to
  hold until maturity are classified as held to maturity.  Securities held to
  maturity are stated at cost, adjusted for amortization of premium and
  accretion of discount, computed primarily under the interest method.
  Securities that are bought and held principally for the purpose of selling
  them in the near term are classified as trading securities.  All other
  securities are classified as available for sale securities.  Unrealized
  holding gains and losses for trading securities are included in earnings.
  Unrealized holding gains and losses for available for sale securities are
  excluded from earnings and reported as a net amount and separate component of
  stockholders' equity until realized.

  As required by Statement No. 115, management implemented the standard on
  January 1, 1994 and classified its entire securities portfolio as available
  for sale due to the identification of circumstances which could result in the
  securities not being held to maturity.  Circumstances resulting in securities
  sales could include, but are not limited to, changes in market interest rates,
  changes in prepayment risk, income tax considerations, and liquidity needs.
  At this time, management has no intention of establishing a trading securities
  classification.


  NOTE E - RECENT ACCOUNTING PRONOUNCEMENTS

  Prior to 1993, the FASB issued Statement No. 107 "Disclosure about Fair Value
  of Financial Instruments" which is effective for fiscal years ending after
  December 15, 1992, except for entities with less than $150 million in total
  assets.  For those entities, the effective date is for fiscal years ending
  after December 15, 1995.  Statement No. 107 requires disclosure of the fair
  value of financial instruments, both assets and liabilities recognized and not
  recognized in the financial statements, with exceptions for certain financial
  instruments.

  In May 1993, the FASB issued Statement No. 114 "Accounting By Creditors for
  Impairment of a Loan" which is effective for fiscal years beginning after
  December 15, 1994.  Statement No. 114 addresses the methods to be used by a
  creditor to measure the impairment of a loan and the proper recognition of a
  change in the value of an impaired loan.

  In October 1994, the FASB issued Statement No. 118 "Accounting by Creditors
  for Impairment of a Loan--Income Recognition and Disclosure" which amends
  Statement No. 114 by allowing creditors to use existing methods for
  recognizing interest income on impaired loans.  Statement No. 118 is effective
  concurrent with the effective date of Statement No. 114.

  In October 1994, the FASB issued Statement No. 119 "Disclosure About
  Derivative Financial Instruments and Fair Value of Financial Instruments"
  which is effective for calendar year 1994 financial statements, except for
  entities with less than $150 million in total assets having a one year delay.
  Statement No. 119 primarily requires disclosures about the amounts, nature and
  terms of derivatives that do not fall under FASB's Statement No. 105
  "Disclosures of Information about Financial Instruments with Off-Balance Sheet
  Risk and Financial Instruments with Concentrations of Credit Risk."

  NOTE E - RECENT ACCOUNTING PRONOUNCEMENTS (CONTINUED)

  Management implemented the above applicable standards for the three months
  ended March 31, 1995 and determined that the combined financial statement
  impact of these statements was not material.  Management is currently
  evaluating the financial statement impact of Statement No. 107.


  NOTE F - PROPOSED MERGER

  On January 5, 1995, Shawnee Financial Services Corporation entered into a
  merger agreement with Keystone Financial, Inc., a Pennsylvania corporation
  (Keystone).  Under the terms of the agreement, Shawnee will be merged with and
  into Keystone, which will be the surviving corporation.  Each outstanding
  share of Shawnee's common stock will be converted into 6.25 shares, subject to
  adjustment, of Keystone common stock, par value $2.00 per share.
  Simultaneously with or following the merger, Shawnee's subsidiary, The Everett
  Bank, will be merged with and into Mid-State Bank and Trust Company, a
  Pennsylvania bank and trust company and wholly-owned subsidiary of Keystone.
  Management believes the merger will be finalized during 1995.

                          [Form of Fairness Opinion]


  Board of Directors
  Shawnee Financial Services Corporation
  115 East Main Street
  Everett, PA  15537

  Directors:

        You have requested our opinion as to the fairness, from a financial
  point of view, to the shareholders of Shawnee Financial Services Corporation
  ("Shawnee") of the financial terms of the proposed merger whereby Shawnee will
  be merged into Keystone Financial, Inc. ("Keystone").  The terms of the
  proposed merger (the "Merger") between Shawnee and Keystone are set forth in
  the Agreement and Plan of Reorganization and the Agreement and Plan of Merger
  (collectively, the "Plan of Merger") dated January 5, 1995, and provide that
  each outstanding share of Shawnee Common Stock will be converted into 6.25
  shares of Keystone Common Stock subject to certain terms and conditions as
  detailed in the Plan of Merger.
    
        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 asset and security transactions,
  including mergers, acquisitions, private placements and valuations 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 Shawnee and Keystone, (ii) reviewed the Plan of Merger, (iii)
  reviewed and analyzed stock market performance of Keystone, (iv) studied and
  analyzed the consolidated financial and operating data of Shawnee and
  Keystone, (v) considered the terms and conditions of the proposed Merger
  between Shawnee and Keystone as compared with the terms and conditions of
  comparable bank mergers and acquisitions, (vi) met and/or communicated with
  certain members of Shawnee's and Keystone's senior managements to discuss
  their respective operations, historical financial statements and future
  prospects, (vii) reviewed the 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 Shawnee and Keystone, and their respective officers, directors,
  auditors, counsel and other agents, and on filings, releases and other
  information issued by Shawnee and Keystone, 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 Shawnee and Keystone 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 Shawnee and Keystone, we have assumed that such information has
  been reasonably prepared and reflects the best currently available

  estimates and judgments of the managements of Shawnee and Keystone as to
  Shawnee's and Keystone's most likely future performance.  In rendering our
  opinion, we have assumed that in the course of obtaining the necessary
  regulatory approvals for the Merger, and in preparation of the final Proxy
  Statement/Prospectus, no conditions will be imposed that will have a material
  adverse effect on the contemplated benefits of the proposed Merger to Shawnee.

        Our opinion is based upon information provided to us by the managements
  of Shawnee and Keystone, 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 Shawnee and does not constitute a recommendation to Shawnee's
  shareholders as to how such shareholders should vote on the Plan of Merger.

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

                                              Sincerely,

        Section 7104(b)(3) (relating to procedure).


        (b)  Exceptions.--

             (1)  Except as otherwise provided in paragraph (2), the holders of
        the shares of any class or series of shares that, at the record date
        fixed to determine the shareholders entitled to notice of and to vote at
        the meeting at which a plan specified in any of section 1930, 1931(d),

<PAGE>
 
          (ii) held of record by more than 2,000 shareholders;

     shall not have the right to obtain payment of the fair value of any such
     shares under this subchapter.

          (2) Paragraph (1) shall not apply to and dissenters rights shall be
     available without regard to the exception provided in that paragraph in the
     case of:

          (i)   Shares converted by a plan if the shares are not converted
                solely into shares of the acquiring, surviving, new or other

                fractional shares.

          (ii)  Shares of any preferred or special class unless the articles,
                the plan or the terms of the transaction entitle all

                adoption of the plan or the effectuation of the transaction the
                affirmative vote of a majority of the votes cast by all
                shareholders of the class.

     shares, property or assets of another corporation by the issuance of 
     shares, obligations or otherwise, with or without assuming the liabilities
     of the other corporation and with or without the intervention of another 
     corporation or other person, shall not be entitled to the rights and 
     remedies of dissenting shareholders provided in this subchapter regardless
     of the fact, if it be the case, that the acquisition was accomplished by 
     the issuance of voting shares of the corporation to be outstanding 
     immediately after the acquisition sufficient to elect a majority or more 
     of the directors of the corporation.

     (c) Grant of optional dissenters rights.--The bylaws or a resolution of
the board of directors may direct that all or a part of the shareholders shall
have dissenters rights in connection with any corporate action or other
transaction that would otherwise not entitle such shareholders to dissenters
rights.

     (d) Notice of dissenters rights.--Unless otherwise provided by statute,
if a proposed corporate action that would give rise to dissenters rights under
this subpart is submitted to a vote at a meeting of shareholders, there shall
be included in or enclosed with the notice of meeting:

          (1) a statement of the proposed action and a statement that the
     shareholders have a right to dissent and obtain payment of the fair value
     of their shares by complying with the terms of this subchapter; and

          (2) a copy of this subchapter.

     (e) Other statutes.--The procedures of this subchapter shall also be
applicable to any transaction described in any statute other than this part

be relaxed by any provision of the articles.

     (g) Cross references.--See sections 1105 (relating to restriction on
equitable relief), 1904 (relating to de facto transaction doctrine abolished)

<PAGE>
 
  (S) 1572.  Definitions.

        The following words and phrases when used in this subchapter shall have
  the meanings given to them in this section unless the context clearly
  indicates otherwise:

        "Corporation."  The issuer of the shares held or owned by the dissenter
  before the corporate action or the successor by merger, consolidation,
  division, conversion or otherwise of that issuer.  A plan of division may
  designate which of the resulting corporations is the successor corporation for
  purpose of this subchapter.  The successor corporation in a division shall
  have sole responsibility for payments to dissenters and other liabilities
  under this subchapter except as otherwise provided in the plan of division.

        "Dissenter."  A shareholder or beneficial owner who is entitled to and
  does assert dissenters rights under this subchapter and who has performed
  every act required up to the time involved for the assertion of those rights.

        "Fair value."  The fair value of shares immediately before the
  effectuation of the corporate action to which the dissenter objects, taking
  into account all relevant factors, but excluding any appreciation or
  depreciation in anticipation of the corporate action.

        "Interest."  Interest from the effective date of the corporate action
  until the date of payment at such rate as is fair and equitable under all of
  the circumstances, taking into account all relevant factors including the
  average rate currently paid by the corporation on its principal bank loans.


  (S) 1573.  Record and beneficial holders and owners.

        (a) Record holders of shares.--A record holder of shares of a business
  corporation may assert dissenters rights as to fewer than all of the shares
  registered in his name only if he dissents with respect to all the shares of
  the same class or series beneficially owned by any one person and discloses
  the name and address of the person or persons on whose behalf he dissents.  In
  that event, his rights shall be determined as if the shares as to which he has
  dissented and his other shares were registered in the names of different
  shareholders.

        (b) Beneficial owners of shares.--A beneficial owner of shares of a
  business corporation who is not the record holder may assert dissenters rights
  with respect to shares held on his behalf and shall be treated as a dissenting
  shareholder under the terms of this subchapter if he submits to the
  corporation not later than the time of the assertion of dissenters rights a
  written consent of the record holder.  A beneficial owner may not dissent with
  respect to some but less than all shares of the same class or series owned by
  the owner, whether or not the shares so owned by him are registered in his
  name.


  (S) 1574.  Notice of intention to dissent.

        If the proposed corporate action is submitted to a vote at a meeting of
  shareholders of a business corporation, any person who wishes to dissent and
  obtain payment of the fair value of his shares must file with the corporation,
  prior to the vote, a written notice of intention to demand that he be paid the
  fair value for his shares if the proposed action is effectuated, must effect
  no change in the beneficial ownership of his shares from the date of such
  filing continuously through the effective date of the proposed action and must
  refrain from voting his shares in approval of such action.  A dissenter who
  fails in any respect shall not acquire any right to payment of the fair value
  of his shares under this subchapter.  Neither a proxy nor a vote against the
  proposed corporate action shall constitute the written notice required by this
  section.

                                      A-5
<PAGE>
 
  (S) 1575.  Notice to demand payment.

        (a) General rule.--If the proposed corporate action is approved by the
  required vote at a meeting of shareholders of a business corporation, the
  corporation shall mail a further notice to all dissenters who gave due notice
  of intention to demand payment of the fair value of their shares and who
  refrained from voting in favor of the proposed action.  If the proposed
  corporate action is to be taken without a vote of shareholders, the
  corporation shall send to all shareholders who are entitled to dissent and
  demand payment of the fair value of their shares a notice of the adoption of
  the plan or other corporate action.  In either case, the notice shall:

          (1) State where and when a demand for payment must be sent and
     certificates for certificated shares must be deposited in order to obtain
     payment.

          (2) Inform holders of uncertificated shares to what extent transfer of
     shares will be restricted from the time that demand for payment is 
     received.

          (3) Supply a form for demanding payment that includes a request for
     certification of the date on which the shareholder, or the person on whose
     behalf the shareholder dissents, acquired beneficial ownership of the 
     shares.

          (4) Be accompanied by a copy of this subchapter.

        (b) Time for receipt of demand for payment.--The time set for receipt of
  the demand and deposit of certificated shares shall be not less than 30 days
  from the mailing of the notice.


  (S) 1576.  Failure to comply with notice to demand payment, etc.

        (a) Effect of failure of shareholder to act.--A shareholder who fails to
  timely demand payment, or fails (in the case of certificated shares) to timely
  deposit certificates, as required by a notice pursuant to section 1575
  (relating to notice to demand payment) shall not have any right under this
  subchapter to receive payment of the fair value of his shares.

        (b) Restriction on uncertificated shares.--If the shares are not
  represented by certificates, the business corporation may restrict their
  transfer from the time of receipt of demand for payment until effectuation of
  the proposed corporate action or the release of restrictions under the terms
  of section 1577(a) (relating to failure to effectuate corporate action).

        (c) Rights retained by shareholder.--The dissenter shall retain all
  other rights of a shareholder until those rights are modified by effectuation
  of the proposed corporate action.


  (S) 1577.  Release of restrictions or payment for shares.

        (a)  Failure to effectuate corporate action.--Within 60 days after the
  date set for demanding payment and depositing certificates, if the business
  corporation has not effectuated the proposed corporate action, it shall return
  any certificates that have been deposited and release uncertificated shares
  from any transfer restrictions imposed by reason of the demand for payment.

        (b)  Renewal of notice to demand payment.--When uncertificated shares
  have been released from transfer restrictions and deposited certificates have
  been returned, the corporation may at any later time send a new notice
  conforming to the requirements of section 1575 (relating to notice to demand
  payment), with like effect.

                                      A-6
<PAGE>
 
        (c)  Payment of fair value of shares.--Promptly after effectuation of
  the proposed corporate action, or upon timely receipt of demand for payment if
  the corporate action has already been effectuated, the corporation shall
  either remit to dissenters who have made demand and (if their shares are
  certificated) have deposited their certificates the amount that the
  corporation estimates to be the fair value of the shares, or give written
  notice that no remittance under this section will be made.  The remittance or
  notice shall be accompanied by:

          (1)  The closing balance sheet and statement of income of the issuer
     of the shares held or owned by the dissenter for a fiscal year ending not
     more than 16 months before the date of remittance or notice together with
     the latest available interim financial statements.

          (2)  A statement of the corporation's estimate of the fair value of 
     the shares.

          (3)  A notice of the right of the dissenter to demand payment or
     supplemental payment, as the case may be, accompanied by a copy of this
     subchapter.

        (d) Failure to make payment.--If the corporation does not remit the
  amount of its estimate of the fair value of the shares as provided by
  subsection (c), it shall return any certificates that have been deposited and
  release uncertificated shares from any transfer restrictions imposed by reason
  of the demand for payment.  The corporation may make a notation on any such
  certificate or on the records of the corporation relating to any such
  uncertificated shares that such demand has been made.  If shares with respect
  to which notation has been made shall be transferred, each new certificate
  issued therefor or the records relating to any transferred uncertificated
  shares shall bear a similar notation, together with the name of the original
  dissenting holder or owner of such shares.  A transferee of such shares shall
  not acquire by such transfer any rights in the corporation other than those
  which the original dissenter had after making demand for payment of their fair
  value.


  (S) 1578.  Estimate by dissenter of fair value of shares.

        (a) General rule.--If the business corporation gives notice of its
  estimate of the fair value of the shares, without remitting such amount, or
  remits payment of its estimate of the fair value of a dissenter's shares as
  permitted by section 1577(c) (relating to payment of fair value of shares) and
  the dissenter believes that the amount stated or remitted is less than the
  fair value of his shares, he may send to the corporation his own estimate of
  the fair value of the shares, which shall be deemed a demand for payment of
  the amount or the deficiency.

        (b) Effect of failure to file estimate.--Where the dissenter does not
  file his own estimate under subsection (a) within 30 days after the mailing by
  the corporation of its remittance or notice, the dissenter shall be entitled
  to no more than the amount stated in the notice or remitted to him by the
  corporation.


  (S) 1579.  Value proceedings general.

        (a) General rule.--Within 60 days after the latest of:

          (1) effectuation of the proposed corporate action;

          (2) timely receipt of any demands for payment under section 1575
     (relating to notice to demand payment); or
 
          (3) timely receipt of any estimates pursuant to section 1578 (relating
     to estimate by dissenter of fair value of shares);

  if any demands for payment remain unsettled, the business corporation may file
  in court an application for relief requesting that the fair value of the
  shares be determined by the court.

                                      A-7
<PAGE>
 
        (b) Mandatory joinder of dissenters.--All dissenters, wherever residing,
  whose demands have not been settled shall be made parties to the proceeding as
  in an action against their shares.  A copy of the application shall be served
  on each such dissenter.  If a dissenter is a nonresident, the copy may be
  served on him in the manner provided or prescribed by or pursuant to 42 Pa.
  C.S. Ch. 53 (relating to bases of jurisdiction and interstate and
  international procedure).

        (c) Jurisdiction of the court.--The jurisdiction of the court shall be
  plenary and exclusive.  The court may appoint an appraiser to receive evidence
  and recommend a decision on the issue of fair value.  The appraiser shall have
  such power and authority as may be specified in the order of appointment or in
  any amendment thereof.

        (d) Measure of recovery.--Each dissenter who is made a party shall be
  entitled to recover the amount by which the fair value of his shares is found
  to exceed the amount, if any, previously remitted, plus interest.

        (e) Effect of corporation's failure to file application.--If the
  corporation fails to file an application as provided in subsection (a), any
  dissenter who made a demand and who has not already settled his claim against
  the corporation may do so in the name of the corporation at any time within 30
  days after the expiration of the 60-day period.  If a dissenter does not file
  an application within the 30-day period, each dissenter entitled to file an
  application shall be paid the corporation's estimate of the fair value of the
  shares and no more, and may bring an action to recover any amount not
  previously remitted.


  (S) 1580.  Costs and expenses of valuation proceedings.

        (a) General rule.--The costs and expenses of any proceeding under
  section 1579 (relating to valuation proceedings generally), including the
  reasonable compensation and expenses of the appraiser appointed by the court,
  shall be determined by the court and assessed against the business corporation
  except that any part of the costs and expenses may be apportioned and assessed
  against all or some of the dissenters who are parties and whose action in
  demanding supplemental payment under section 1578 (relating to estimate by
  dissenter of fair value of shares) the court finds to be dilatory, obdurate,
  arbitrary, vexatious or in bad faith.

        (b) Assessment of counsel fees and expert fees where lack of good faith
  appears.--Fees and expenses of counsel and of experts for the respective
  parties may be assessed as the court deems appropriate against the corporation
  and in favor of any or all dissenters if the corporation failed to comply
  substantially with the requirements of this subchapter and may be assessed
  against either the corporation or a dissenter, in favor of any other party, if
  the court finds that the party against whom the fees and expenses are assessed
  acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner
  in respect to the rights provided by this subchapter.

        (c) Award of fees for benefits to other dissenters.--If the court finds
  that the services of counsel for any dissenter were of substantial benefit to
  other dissenters similarly situated and should not be assessed against the
  corporation, it may award to those counsel reasonable fees to be paid out of
  the amounts awarded to the dissenters who were benefited.

  Dear Shareholder:
    
        A Special Meeting of the Shareholders of the Shawnee Financial Services
  Corporation ("Shawnee") will be held on Tuesday, August 1, 1995, at 11:00
  a.m., local time, at the Board Room of The Everett Bank, 115 East Main Street,
  Everett, Pennsylvania 15537.
     
        The purpose of the Special Meeting is to consider and vote upon a
  proposal to approve an Agreement and Plan of Reorganization and a related
  Agreement and Plan of Merger (collectively, the "Plan of Merger") providing
  for the merger of Shawnee into Keystone Financial, Inc. ("Keystone").
  Keystone is a bank holding company with its principal office in Harrisburg,
  Pennsylvania.  Through its subsidiary banks, Keystone currently maintains 140
  banking offices in central and southeastern Pennsylvania, western Maryland and
  northeastern West Virginia.
    
        If the merger is approved, Shawnee shareholders will receive 6.25 shares
  of Keystone Common Stock in exchange for each share of Shawnee Common Stock
  owned by them.  Upon consummation of the merger, Shawnee shareholders will no
  longer hold any interest in Shawnee.  Instead, you will be a shareholder of
  Keystone.  Keystone Common Stock is quoted on the NASDAQ National Market
  System under the symbol "KSTN."  Based on the June 20, 1995 closing sale price
  for Keystone Common Stock of $28.125 per share, the value of the 6.25 shares
  of Keystone Common Stock being offered for each Shawnee share in the merger
  would be $175.78.  Shareholders should note that the market value of the
  Keystone Common Stock may change prior to consummation of the merger.
  SHAREHOLDERS ARE ENCOURAGED TO READ AND CAREFULLY CONSIDER THE ATTACHED  PROXY
  STATEMENT/PROSPECTUS WHICH CONTAINS A MORE COMPLETE DESCRIPTION OF THE TERMS
  OF THE PROPOSED MERGER AND PROVIDES DETAILED FINANCIAL, BUSINESS AND OTHER
  INFORMATION CONCERNING SHAWNEE AND KEYSTONE.
     
        The Board of Directors of Shawnee has carefully considered the Plan of
  Merger and believes that the proposed merger is in the best interests of
  Shawnee and its shareholders.  ACCORDINGLY, YOUR BOARD OF DIRECTORS
  UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE PLAN OF MERGER.  All
  the executive officers and directors of Shawnee have advised Shawnee of their
  intention to vote the shares of Shawnee Common Stock owned by them in favor of
  the Plan of Merger.
    
        The affirmative vote of the holders of 75% of all outstanding shares of
  Shawnee Common Stock is necessary for approval of the Plan of Merger.  Your
  vote is important regardless of the number of shares you own.  We urge you to
  participate in this significant development by marking, signing, dating and
  returning promptly the enclosed proxy in the accompanying postage paid, pre-
  addressed envelope, whether or not you plan to attend the Special Meeting.
  You will retain the right to vote your shares in person at the Special Meeting
  if you so desire.  All properly executed proxies not previously revoked will
  be voted at the Special Meeting in accordance with the instructions given on
  the proxy.  Proxies containing no voting instructions regarding the proposal
  to approve the Plan of Merger will be voted in favor of the merger.
     
                                         Sincerely yours,



                                         Samuel K. Bohn
