         At this important Annual Meeting, shareholders will be asked to adopt
among other things, an Agreement of Affiliation and Plan of Merger, dated as of
February 6, 1998 (the "Merger Agreement"), by and between FirstFederal and First
Shenango Bancorp, Inc. ("First Shenango"), pursuant to which First Shenango will
merge with and into FirstFederal, with FirstFederal as the surviving
corporation, (the "Merger"), and FirstFederal will issue shares of its common
stock to shareholders of First Shenango. The terms of the Merger, including the
method for determining the amount of FirstFederal common stock to be issued as
well as other important information relating to FirstFederal, First Shenango and
the combined company, are contained in the accompanying Joint Proxy
Statement/Prospectus. Please give this document your careful attention.

         The Board of Directors of FirstFederal has carefully reviewed and
considered the terms and conditions of the Merger Agreement. THE BOARD OF
DIRECTORS OF FIRSTFEDERAL HAS CONCLUDED THAT THE MERGER AGREEMENT AND THE
PROPOSED MERGER ARE IN THE BEST INTEREST OF THE SHAREHOLDERS OF FIRSTFEDERAL,
AND UNANIMOUSLY RECOMMENDS THAT FIRSTFEDERAL SHAREHOLDERS VOTE "FOR" THE MERGER
AGREEMENT.

         In addition to adoption of the Merger Agreement, shareholders will be
asked to consider the following additional matters at the Annual Meeting: (i)

the number of shares of common stock authorized for issuance thereunder from
20,000,000 to 40,000,000; (ii) adoption of an amendment to FirstFederal's
Articles of Incorporation to change FirstFederal's name from "FirstFederal
Financial Services Corp" to "Signal Corp"; and (iii) the election of seven
directors to FirstFederal's Board of Directors.

         I encourage you to attend the Annual Meeting in person. Whether or not
you do, please read the Joint Proxy Statement/Prospectus and then complete, sign

This will save FirstFederal additional expense in soliciting proxies and will

at the Annual Meeting even if you have previously returned the proxy.

         Thank you for your prompt attention to this important matter.

                                          Very truly yours,

         The following is a brief summary of certain information contained

Certain capitalized terms used in this summary are defined elsewhere in this
Joint Proxy Statement/Prospectus. This summary is not intended to be a complete
description of all material facts regarding FirstFederal, First Shenango and the
matters to be considered at the FirstFederal Annual Meeting and the First
Shenango Annual Meeting and is qualified in its entirety by, and reference is
made to, the more detailed information contained elsewhere in this Joint Proxy
Statement/Prospectus, the accompanying Appendices and the documents referred to
and incorporated by reference herein.

                            THE PARTIES TO THE MERGER

FIRSTFEDERAL FINANCIAL SERVICES CORP

         FirstFederal, an Ohio corporation, is a bank holding company which has
as its primary wholly-owned subsidiaries Signal Bank, N.A., a national bank
("Signal Bank"), Summit Bank, N.A., a national bank ("Summit Bank") and Mobile
Consultants, Inc., a broker and servicer of manufactured housing finance
contracts ("MCi"). At December 31, 1997, FirstFederal had assets of $1.5
billion, deposits of $981.7 million and shareholders' equity of $104.7 million.
FirstFederal's executive offices are located at 135 East Liberty Street,
Wooster, Ohio 44691, and its telephone number at that address is (330) 264-8001.

         Founded in 1905 as an Ohio chartered stock building and loan
association, Signal Bank (formerly known as First Federal Savings and Loan
Association of Wooster) converted to a federally chartered mutual thrift in
1935, converted from mutual to stock form in 1987, and converted from a savings
and loan association to a national bank in July 1997. On September 15, 1997,
Signal Bank completed the acquisition of seven branches with approximately $151
million in deposits from another institution. Signal Bank serves north central
Ohio (its "Market Area") through its home office, 25 full service banking
offices, and 3 limited service facilities.

         Signal Bank offers a wide range of competitive consumer-oriented
lending and deposit products and services throughout its Market Area. Signal
Bank has achieved significant growth in recent years through the expansion of
its asset origination capabilities and by acquiring branches from other
institutions in its Market Area.

         Summit Bank was acquired by FirstFederal in July 1997. Summit Bank
offers a full complement of banking products and services to small businesses,
individuals and professionals in the Akron, Canton and Cleveland, Ohio
metropolitan areas. Summit Bank operates 2 full service banking offices.

         MCi, a manufactured housing finance company which brokers manufactured
home loans to and on behalf of financial institutions, was acquired by
FirstFederal in April 1996. MCi facilitates the origination of primarily
non-mortgage, consumer loan contracts through 3,500 dealers of manufactured
homes located in 44 states. MCi also services the collection and recovery of
troubled loans on behalf of the financial institutions which originate the
loans.

         In February 1998, FirstFederal formed Signal Capital Trust One ("Signal
Trust"), a Delaware business trust. Signal Trust was formed for the purpose of
(i) issuing and selling $50 million of its 8.67% Capital Securities, Series A
(the "Capital Securities") and common securities (the "Common Securities"), (ii)
investing the proceeds thereof in the 8.67% Junior Subordinated Deferrable
Interest Debentures, Series A, issued by FirstFederal (the "FirstFederal
Debentures") and (iii) engaging in certain other limited activities. The Capital
Securities were issued and sold to investors in a private placement exempt from
the Securities Act of 1933 on February 10, 1998. FirstFederal is the sole owner
of the Common Securities. Distributions on the Capital Securities are guaranteed
by FirstFederal, are cumulative, began cumulating on February 13, 1998 and are
payable semi-annually in arrears on February 15 and August 15 of each year,
commencing August 15, 1998 at the annual rate of 8.67% of the liquidation amount
of $1,000 per security. The interest payment schedule of the FirstFederal
Debentures is identical to that of the Capital Securities, except that so long
as FirstFederal is not in default under the indenture governing the FirstFederal
Debentures, FirstFederal may defer the payment of interest on the FirstFederal
Debentures at any time and from time to time for a period not exceeding ten
consecutive semi-annual periods (an "Extension Period"). During any Extension

                                        1

Period, FirstFederal will be prohibited from taking certain actions, including
declaring or paying any dividends or distributions on or redeeming or purchasing
any of its capital stock.

Financial Data of FirstFederal Financial Services Corp" and "Incorporation of
Certain Documents by Reference."

FIRST SHENANGO BANCORP, INC.

         First Shenango is a unitary savings and loan holding company that was
incorporated in December 1992 under the laws of the Commonwealth of Pennsylvania
for the sole purpose of acquiring all of the issued and outstanding common stock
of First Federal Savings Bank of New Castle ("New Castle Bank"). This
acquisition occurred in connection with the simultaneous conversion on April 5,
1993 of New Castle Bank from a mutual to a stock institution. At December 31,
1997, First Shenango had total assets, deposits and shareholders' equity of
$375.0 million, $275.2 million and $47.9 million, respectively.

         New Castle Bank was founded in 1887 as a Pennsylvania chartered
association under the name of New Castle Mutual Building and Loan Association,
which merged with Equitable Federal Savings and Loan Association of New Castle
in 1940. Its present name was obtained upon completion of the 1993
mutual-to-stock conversion. New Castle Bank is a federally chartered stock
savings bank headquartered in New Castle, Pennsylvania, with three branch
offices located within the surrounding townships.

         Since 1936, New Castle Bank's deposits have been federally insured by
the Savings Association Insurance Fund ("SAIF") of the Federal Deposit Insurance
Corporation and its predecessor, the Federal Savings and Loan Insurance
Corporation, and New Castle Bank has been a member of the Federal Home Loan Bank
System since 1933. New Castle Bank is a community oriented, full service retail
savings institution offering traditional mortgage loan products. During recent
years, New Castle Bank has expanded its loan origination activities to include
multi-family, commercial real estate, consumer, and commercial business loans.

         The Merger will become effective at the time and on the date of the
filing of a certificate of merger with the Secretary of State of the State of
Ohio and articles of merger with the Department of State of the Commonwealth of
Pennsylvania (the "Effective Time"). Consummation of the Merger will occur only
after the approval and adoption of the Merger Agreement by the requisite votes
of First Shenango's and FirstFederal's shareholders and the satisfaction or
waiver of all other conditions to consummation of the Merger. The Merger
Agreement provides that the Merger is to close on or before August 31, 1998, or
as soon as possible after regulatory approval of the Merger is obtained, but in
no event later than December 31, 1998 (the "Closing Date"). See "Effective Time
and Closing Date." In the event the Merger does not close by December 31, 1998,
either First Shenango or FirstFederal may terminate the Merger Agreement if the
failure to consummate the Merger by such date was not caused by a breach of the
Merger Agreement by the terminating party. See "The Merger--Waiver and
Amendment; Termination."

DISSENTERS' RIGHTS

         Any First Shenango shareholder who does not vote in favor of the Merger
Agreement has the right, pursuant to the Pennsylvania Business Corporation Law,
to demand payment from First Shenango of the fair value of his or her shares of
First Shenango Common Stock in lieu of converting such shares into shares of
FirstFederal Common Stock. Strict compliance with the procedures set forth in
the statute is required. See "The Merger--Dissenters' Rights."

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Certain directors, officers and employees of First Shenango may be
deemed to have certain interests in the Merger in addition to their interests
generally as shareholders of First Shenango. It is intended that Francis A.
Bonadio, the President and Chief Executive Officer of First Shenango, and Lonny
D. Robinson, the Vice President and Chief Financial Officer of First Shenango,
will serve as Chief Executive Officer and as President, Chief Financial Officer
and Treasurer, respectively, of New Castle Bank following the Merger pursuant
to employment agreements with terms of six months and three years,
respectively, with New Castle Bank to be effective upon the closing of the
Merger. In addition, the Merger Agreement provides that within 90 days after
the Effective Time, FirstFederal will cause options to purchase 25,000 shares   
of FirstFederal Common Stock to be granted at no cost to officers of New Castle
Bank pursuant to FirstFederal's 1997 Omnibus Incentive Plan. The options will
have an exercise price per share equal to the market value per share of the
FirstFederal Common Stock at the time of grant. The allocation of such options
will be based upon recommendation by the Board of Directors of New Castle Bank,
as approved by the FirstFederal Board. For additional information, see "The
Merger-Interests of Certain Persons in the Merger."

CONDITIONS TO THE MERGER

         The respective obligations of the parties to consummate the Merger are
subject to the satisfaction or waiver of certain conditions specified in the
Merger Agreement, including, among other things, the receipt of the requisite
regulatory and shareholder approvals, the accuracy of the representations and
warranties contained therein, the receipt by FirstFederal of a letter from its
independent public accountants that the Merger will qualify for pooling of
interests accounting treatment, the performance of all obligations imposed by
the Merger Agreement and certain other conditions. See "The Merger--Conditions
to the Merger."

REGULATORY APPROVALS

         The Merger is subject to the approval of the Board of Governors of the
Federal Reserve System (the "FRB"). FirstFederal filed an application for
approval of the Merger with the FRB on March 31, 1998. FirstFederal anticipates

                                        5


<PAGE>   17



receiving the approval of the FRB in the second quarter of 1998. There can be no
assurance as to the receipt or timing of such approval. See "The
Merger--Regulatory Approvals."

WAIVER AND AMENDMENT; TERMINATION

         Either party to the Merger Agreement may waive compliance with any
provision of the Merger Agreement where such waiver is executed in writing by
the waiving party. The Merger Agreement may be amended by execution of the
amendment in writing by both First Shenango and FirstFederal.

         The Merger Agreement may be terminated at any time, whether prior to or
after approval of the Merger Agreement by FirstFederal's and First Shenango's
shareholders: (i) by the vote of a majority of the Board of Directors of each of
FirstFederal and First Shenango; (ii) by the vote of a majority of the Board of
Directors of either FirstFederal or First Shenango if the Merger shall not have
been consummated on or before October 31, 1998, unless the failure to consummate
the Merger by such date is related to the action or inaction of the appropriate
regulatory authorities and such action or inaction is not related to a breach of
the Merger Agreement by the terminating party; (iii) by the vote of a majority
of the Board of Directors of either FirstFederal or First Shenango if any
regulatory authority has denied approval of the Merger; (iv) prior to the
closing of the Merger, by First Shenango, in the event of a material
misrepresentation or breach of warranty or failure to disclose any other matter,
which in the aggregate, would have potential pre-tax liability to FirstFederal
in excess of $3,000,000, and FirstFederal fails to timely cure such defect; (v)
prior to the closing of the Merger, by FirstFederal, in the event of a material
misrepresentation or breach of warranty or failure to disclose any other matter,
which, in the aggregate, would have potential pre-tax liability to First
Shenango in excess of $1,000,000, and First Shenango fails to timely cure such
defect; (vi) at any time after December 31, 1998, by First Shenango or
FirstFederal, if the closing of the Merger shall not have occurred on or before
such date and the failure to consummate the Merger is not caused by a breach of
the Merger Agreement by the terminating party; (vii) by either party if any bona
fide action or proceeding shall be pending against either party on the Closing
Date that could result in an unfavorable judgment, decree, or order that would
prevent or make unlawful the carrying out of the Merger Agreement; (viii) by
either party after regulatory approval of the Merger is obtained if the
conditions to such party's obligations to close have not been satisfied or
waived; or (ix) by First Shenango, if (A) the average of the closing bid and ask
price of FirstFederal Common Stock on the Nasdaq National Market for the ten
consecutive trading days ending on the third trading day prior to the Closing
Date is more than 15% lower than the average of the closing bid and ask price of
FirstFederal Common Stock on the Nasdaq National Market for the ten consecutive
trading days ending on the date prior to the date of the Merger Agreement
($35.40 per share); and (B) the change in the price per share of FirstFederal
Common Stock referred to in clause (A) above exceeds the change in the value of
the SNL Securities National Bank and Thrift Index for the comparable period by
more than .1% (i.e., the change from 359.47). See "The Merger--Waiver and
Amendment; Termination."

CONDUCT OF BUSINESS PENDING THE MERGER

         First Shenango has agreed to conduct its business prior to the
Effective Time diligently and in substantially the same manner as it previously
has been carried out. First Shenango also has agreed to certain forbearances
with respect to the conduct of its business prior to the Effective Time. See
"The Merger--Conduct of Business Pending the Merger."

EXPENSES; BREAK-UP FEE

         All expenses incurred or to be incurred in connection with the Merger
Agreement and the consummation of the transactions contemplated thereby are to
be paid by the party incurring such expenses, except that First Shenango may not
incur any such costs and expenses in excess of $450,000 in the aggregate,
excluding the fee payable to McDonald & Company for financial advisory services.
See "The Merger--Opinion of First Shenango's Financial Advisor." In addition,
under the Merger Agreement, First Shenango must pay FirstFederal a fee of
$3,000,000 in the event the Merger is not consummated and certain events occur.
See "The Merger--Break-Up Fee."

ACCOUNTING TREATMENT

         FirstFederal intends to account for the Merger under the pooling of
interests method of accounting. FirstFederal and First Shenango have each agreed
to take no actions which would prevent FirstFederal from utilizing the pooling
of interests method. In addition, it is a condition to FirstFederal's
obligations under the Merger Agreement that FirstFederal receive a letter from
KPMG Peat Marwick LLP to the effect that the Merger will qualify

                                        6


<PAGE>   18



for pooling of interests accounting treatment. See "The Merger--Conditions to
the Merger--Resales of FirstFederal Common Stock by Affiliates" and
"--Accounting Treatment."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         FirstFederal has received an opinion of Critchfield, Critchfield &
Johnston, Ltd. to the effect that if the Merger were consummated on the date
hereof, the following federal income tax consequences would result:

                  (i) the Merger would qualify as a reorganization under 
                  Section 368(a) of the Code;

                  (ii) no gain or loss would be recognized by FirstFederal or
                  First Shenango by reason of the Merger;

                  (iii) no gain or loss would be recognized by any First
                  Shenango shareholder upon the exchange of First Shenango
                  Common Stock solely for FirstFederal Common Stock in the
                  Merger (see items (vi) and (vii) below regarding tax treatment
                  with respect to the receipt of cash in lieu of a fractional
                  share of FirstFederal Common Stock or the receipt of cash in
                  connection with the exercise of dissenter rights);

                  (iv) the aggregate tax basis of the FirstFederal Common Stock
                  received by each shareholder of First Shenango who exchanged
                  First Shenango Common Stock for FirstFederal Common Stock in
                  the Merger would be the same as the aggregate tax basis of the
                  First Shenango Common Stock surrendered in exchange therefor
                  (subject to any adjustments required as the result of receipt
                  of cash in lieu of a fractional share of FirstFederal Common
                  Stock);

                  (v) the holding period of the shares of FirstFederal Common
                  Stock received by a First Shenango shareholder in the Merger
                  would include the holding period of the First Shenango Common
                  Stock surrendered in exchange therefor (provided that such
                  shares of First Shenango Common Stock were held as capital
                  assets by such shareholder at the Effective Time);

                  (vi) cash received in the Merger by a First Shenango
                  shareholder in lieu of a fractional share interest of
                  FirstFederal Common Stock would be treated as having been
                  received as a distribution in full payment in exchange for the
                  fractional share interest of FirstFederal Common Stock which
                  such shareholder would otherwise be entitled to receive, and
                  would qualify as capital gain or loss (assuming the First
                  Shenango Common Stock surrendered in exchange therefor were
                  held as a capital asset by such shareholder at the Effective
                  Time); and

                  (vii) a First Shenango shareholder who received only cash as a
                  result of the exercise of dissenter rights would realize gain
                  or loss for federal income tax purposes (determined separately
                  as to each block of First Shenango Common Stock exchanged) in
                  an amount equal to the difference between (x) the amount of
                  cash received by such shareholder, and (y) such shareholder's
                  tax basis for the shares of First Shenango Common Stock
                  surrendered in exchange therefor, provided that the cash
                  payment did not have the effect of the distribution of a
                  dividend. Any such gain or loss would be recognized for
                  federal income tax purposes and would be treated as capital
                  gain or loss (assuming the First Shenango Common Stock
                  surrendered in exchange therefor were held as a capital asset
                  by such shareholder at the Effective Time). However, if the
                  cash payment did have the effect of the distribution of a
                  dividend, the amount of taxable income recognized would equal
                  the amount of cash received; such income generally would be
                  taxable as a dividend and no loss (or other recovery of such
                  shareholder's tax basis for the shares of First Shenango
                  Common Stock surrendered in the exchange) generally would be
                  recognized by such shareholder. The determination of whether a
                  cash payment has the effect of the distribution of a dividend
                  would be made pursuant to the provisions and limitations of
                  Section 302 of the Internal Revenue Code of 1986, as amended
                  (the "Code"), taking into account the constructive stock
                  ownership rules of Section 318 of the Code.

         The opinion is subject to various assumptions and qualifications,
including that the Merger will be consummated in the manner and in accordance
with the terms of the Merger Agreement. The opinion is based entirely upon the
Code, regulations currently in effect or proposed thereunder, current
administrative rulings and practice and judicial authority, all of which are
subject to change, possibly with retroactive effect.

         First Shenango shareholders are urged to consult their personal tax
advisors concerning the specific tax consequences to them of the Merger,
including the applicability and effect of various state, local and foreign tax
laws. For further discussion of the opinion regarding the federal income tax
consequences of the Merger, as issued and delivered to the FirstFederal Board,
see "The Merger--Certain Federal Income Tax Consequences of the Merger."

EFFECT OF THE MERGER ON RIGHTS OF SHAREHOLDERS

         As a result of the Merger, shareholders of First Shenango, a
Pennsylvania corporation, will become shareholders of FirstFederal, an Ohio
corporation. For a comparison of the respective rights of shareholders of
FirstFederal and First Shenango, as defined by Ohio and Pennsylvania law and the
respective corporate governance documents of FirstFederal and First Shenango,

</TABLE>

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

(1)  The pro forma combined book value per common share represents the
     historical combined shareholders' equity of FirstFederal and First
     Shenango, including the effect of pro forma adjustments. The adjusted
     shareholders' equity amounts are divided by the number of shares of
     FirstFederal diluted common stock outstanding at December 31, 1997, plus
     the product of the number of shares of First Shenango Common Stock
     outstanding at December 31, 1997 and the Exchange Ratio (1.143). The number
     of shares of FirstFederal Common Stock outstanding at December 31, 1997
     includes 2,170,000 common stock equivalents attributable to FirstFederal's
     convertible preferred stock Series B outstanding at December 31, 1997.

(2)  The pro forma combined cash dividends declared per common share represent
     the historical cash dividends declared per share on FirstFederal Common
     Stock. The pro forma equivalent cash dividends declared per share represent
     the cash dividends declared on one share of FirstFederal Common Stock
     multiplied by the Exchange Ratio of 1.143. No assurance can be made that
     equivalent dividends will be paid in the future. The amount of dividends
     payable will be dependent upon, among other things, the earnings and
     financial condition of the combined company.

(3)  Pro forma combined per share income amounts are based upon the combined
     historical income amounts and pro forma combined weighted average common
     and common equivalent shares outstanding. The pro forma weighted average
     common and common equivalent shares of FirstFederal Common Stock
     outstanding for the periods indicated include the weighted average number
     of common and common equivalent shares of FirstFederal Common Stock
     outstanding for the periods indicated plus the product of the weighted
     average number of common and common equivalent shares of First Shenango
     Common Stock outstanding for the periods indicated and the Exchange Ratio
     of 1.143. The First Shenango pro forma equivalent per share income amounts
     represent the pro forma combined per share income amounts multiplied by the
     Exchange Ratio of 1.143.

(4)  Excluding FirstFederal's one-time SAIF assessment of $3.3 million ($2.2
     million after tax), FirstFederal's 1996 diluted earnings per share were
     1.75; excluding First Shenango's one-time SAIF assessment of $1.7 million
     ($1.1 million after tax), First Shenango's 1996 diluted earnings per share
     were $1.80 the combined per share amount would be $1.71 and the First

                                  THE MEETINGS

FIRSTFEDERAL ANNUAL MEETING

          Place, Time and Date. The FirstFederal Annual Meeting will be held at
the Black Tie Affair Conference Center, located at 50 Riffel Road, Wooster, Ohio
at 9:00 a.m., local time, on June 16, 1998. This Joint Proxy
Statement/Prospectus is being sent to holders of FirstFederal Common Stock and
accompanies a form of proxy (the "FirstFederal Proxy") which is being solicited
by the FirstFederal Board for use at the FirstFederal Annual Meeting and at any
and all adjournments or postponements thereof.

          Matters to Be Considered. At the FirstFederal Annual Meeting, holders
of shares of FirstFederal Common Stock will vote on the following proposals (the
"FirstFederal Proposals"): (i) the adoption of the Merger Agreement; (ii) the
adoption of an amendment to FirstFederal's Articles of Incorporation (the
"FirstFederal Articles") to increase the number of shares of FirstFederal Common
Stock authorized for issuance thereunder from 20,000,000 to 40,000,000 (the
"FirstFederal Share Increase Proposal"); (iii) the adoption of an amendment to
the FirstFederal Articles to change the name of FirstFederal from "FirstFederal
Financial Services Corp" to "Signal Corp" (the "FirstFederal Name Change
Proposal"); and (iv) the election of seven directors of FirstFederal (the
"Election of the FirstFederal Directors"). See "The Merger," "Amendment to
FirstFederal's Articles of Incorporation to Increase Authorized Shares,"
"Amendment to FirstFederal's Articles of Incorporation to Change Name" and
"Election of FirstFederal Directors."

          FirstFederal shareholders will also consider and vote upon such other
matters as may properly be brought before the FirstFederal Annual Meeting. As of
the date hereof, the FirstFederal Board knows of no business that will be
presented for consideration at the FirstFederal Annual Meeting other than the
matters described in this Joint Proxy Statement/Prospectus.

          FirstFederal Record Date; Vote Required. The FirstFederal Board has
fixed the close of business on May 4, 1998 (the "FirstFederal Record Date") as
the date for determining holders of FirstFederal Common Stock who will be
entitled to notice of, and to vote at the FirstFederal Annual Meeting. As of the
FirstFederal Record Date there were outstanding and entitled to vote at the
FirstFederal Annual Meeting 6,756,868 shares of FirstFederal Common Stock.

          Each holder of record of shares of FirstFederal Common Stock on the
FirstFederal Record Date will be entitled to cast one vote per share on the
FirstFederal Proposals at the FirstFederal Annual Meeting. Such vote may be
exercised in person or by properly executed proxy. The presence, in person or by
properly executed proxy, of any number of FirstFederal Common Stock is necessary
to constitute a quorum. Abstentions and broker non-votes (i.e., proxies from
brokers or nominees indicating that such persons have not received instructions
from the beneficial owners or other persons as to certain proposals on which
such beneficial owners or persons are entitled to vote their shares but with
respect to which the brokers or nominees have no discretionary power to vote
without such instructions) will be treated as shares present at the FirstFederal
Annual Meeting for purposes of determining the presence of a quorum.

          The affirmative vote of the holders of a majority of the outstanding
shares of FirstFederal Common Stock is required for adoption of the Merger
Agreement, the FirstFederal Share Increase Proposal and the FirstFederal Name
Change Proposal. Therefore, abstentions and broker non-votes will have the same
effect as votes against adoption of the Merger Agreement, the FirstFederal Share
Increase Proposal and the FirstFederal Name Change Proposal. The Election of the
FirstFederal Directors requires a plurality of the votes cast at the
FirstFederal Meeting. Votes withheld and broker non-votes will have no effect on
the Election of the FirstFederal Directors.

          As of the FirstFederal Record Date, the directors and executive
officers of FirstFederal and their affiliates beneficially owned in the
aggregate 1,149,956 shares of FirstFederal Common Stock (including 162,261
shares underlying stock options currently exercisable or which will become
exercisable within 60 
                                       17

days of May 4, 1998 and 40,650 shares issuable upon conversion of shares of
FirstFederal's Series B Preferred Stock), or approximately 16.52% of the then
outstanding shares of FirstFederal Common Stock entitled to vote at the
FirstFederal Annual Meeting. As of such date, neither First Shenango and its
subsidiaries, nor the directors and executive officers of First Shenango and
their affiliates, beneficially owned any shares of FirstFederal Common Stock.

          Proxies. Shares of FirstFederal Common Stock represented by properly
executed proxies received prior to or at the FirstFederal Annual Meeting will,
unless such proxies have been revoked, be voted at the FirstFederal Annual
Meeting and any adjournments or postponements thereof, in accordance with the
instructions indicated in the proxies. If no instructions are indicated on a
properly executed FirstFederal Proxy, the shares will be voted FOR the
FirstFederal Proposals.

          Any FirstFederal Proxy given pursuant to this solicitation may be
revoked at any time before it is voted. Proxies may be revoked by (i) filing
with the Secretary of FirstFederal at or before the FirstFederal Annual Meeting
a written notice of revocation bearing a later date than the FirstFederal Proxy,
(ii) duly executing a subsequent proxy relating to the same shares and
delivering it to the Secretary of FirstFederal at or before the FirstFederal
Annual Meeting, or (iii) attending the FirstFederal Annual Meeting and voting in
person (although attendance at the FirstFederal Annual Meeting will not in and
of itself constitute revocation of a proxy). Any written notice revoking a proxy
should be delivered to L. Dwight Douce, Secretary, FirstFederal Financial
Services Corp, 135 East Liberty Street, Wooster, Ohio 44691.

          If any other matters are properly presented at the FirstFederal Annual
Meeting for consideration, the persons named in the FirstFederal Proxy or acting
thereunder will have discretion to vote on such matters in accordance with their
best judgment. As of the date hereof, the FirstFederal Board knows of no such
other matters.

          In addition to solicitation by mail, directors, officers and employees
of FirstFederal, who will not be specifically compensated for such services, may
solicit proxies from the stockholders of FirstFederal, personally or by
telephone, telegram or other forms of communication. Brokerage houses, nominees,
fiduciaries and other custodians will be requested to forward soliciting
materials to beneficial owners and will be reimbursed for their reasonable
expenses incurred in sending proxy material to beneficial owners. FirstFederal
will bear its own expenses in connection with the solicitation of proxies for
the FirstFederal Annual Meeting. See "The Merger--Expenses."

          HOLDERS OF FIRSTFEDERAL COMMON STOCK ARE REQUESTED TO COMPLETE, DATE
AND SIGN THE ACCOMPANYING FIRSTFEDERAL PROXY AND RETURN IT PROMPTLY IN THE
ENCLOSED POSTAGE-PAID ENVELOPE.

          Voting Securities and Certain Holders Thereof. The following table
sets forth, as of May 4, 1998, certain information as to (i) those persons who
were known by management to be beneficial owners of more than 5% of the
outstanding shares of FirstFederal Common Stock and (ii) the shares of
FirstFederal Common Stock beneficially owned by the directors, nominees and
executive officers of FirstFederal as a group. For information regarding the
beneficial ownership of FirstFederal Common Stock by the individual directors
and nominees of FirstFederal, see "Election of FirstFederal Directors."

FIRST SHENANGO ANNUAL MEETING

         Place, Time and Date. The First Shenango Annual Meeting will be held at
First Shenango's headquarters, located at 25 North Mill Street, New Castle,
Pennsylvania, at 4:00 p.m., local time, on June 23, 1998. This Joint Proxy
Statement/Prospectus is being sent to holders of First Shenango Common Stock,
and accompanies a form of proxy (the "First Shenango Proxy") which is being
solicited by the First Shenango Board for use at the First Shenango Annual
Meeting and at any and all adjournments or postponements thereof.

         Matters to Be Considered. At the First Shenango Annual Meeting, holders
of First Shenango Common Stock will vote upon the following proposals (the
"First Shenango Proposals"): (i) approval of the Merger Agreement; and (ii) the
election of two directors of First Shenango (the "Election of the First Shenango
Directors").

         Holders of First Shenango Common Stock will also consider and vote upon
such other matters as may properly be brought before the First Shenango Annual
Meeting. As of the date hereof, the First Shenango Board knows of no business
that will be presented for consideration at the First Shenango Annual Meeting,
other than the matters described in this Joint Proxy Statement/Prospectus.

         First Shenango Record Date; Vote Required. The First Shenango Board has
fixed the close of business on May 4, 1998 (the "First Shenango Record Date"),
as the date for determining holders of First Shenango Common Stock who will be
entitled to notice of, and to vote at, the First Shenango Annual Meeting. As of
the First Shenango Record Date, there were outstanding and entitled to vote at
the First Shenango Annual Meeting [2,069,007] shares of First Shenango Common
Stock.

         Each holder of record of First Shenango Common Stock on the First
Shenango Record Date will be entitled to cast one vote per share on the First
Shenango Proposals at the First Shenango Annual Meeting. Such vote may be
exercised in person or by properly executed proxy. The presence, in person or by
properly executed proxy, of the holders of a majority of the outstanding shares
of First Shenango Common Stock entitled to vote at the First Shenango Annual
Meeting is necessary to constitute a quorum. Abstentions and broker non-votes
will be treated as shares present at the First Shenango Annual Meeting for
purposes of determining the presence of a quorum.

         The affirmative vote of the holders of a majority of the outstanding
shares of First Shenango Common Stock is required for approval of the Merger
Agreement. Therefore, abstentions and broker non-votes will have the same effect
as votes against approval of the Merger Agreement. The Election of the First
Shenango Directors requires a plurality of the votes cast at the First Shenango
Annual Meeting. Votes withheld and broker non-votes will have no effect on the
Election of the First Shenango Directors.

         As of the First Shenango Record Date, the directors and executive
officers of First Shenango and their affiliates beneficially owned in the
aggregate 243,383 shares of First Shenango Common Stock (including 97,339
shares underlying stock options currently exercisable or which will become
exercisable within 60 days of May 4, 1998), or approximately 11.23% of the 
then outstanding shares of First Shenango Common Stock entitled to vote
at the First Shenango Annual Meeting. As of the First Shenango Record Date, the
directors and executive officers of FirstFederal and their affiliates
beneficially owned in the aggregate 30,475 shares of First Shenango Common
Stock, or 1.47% of the then outstanding shares of First Shenango Common Stock
entitled to vote at the First Shenango Special Meeting.

         Proxies. Shares of First Shenango Common Stock represented by properly
executed proxies received prior to or at the First Shenango Annual Meeting will,
unless such proxies have been revoked, be voted at the First Shenango Annual
Meeting and any adjournments or postponements thereof in accordance with the
instructions

                                       20


<PAGE>   32
indicated in the proxies. If no instructions are indicated on a properly
executed First Shenango Proxy, the shares will be voted FOR the First Shenango
Proposals.

         Any First Shenango Proxy given pursuant to this solicitation or
otherwise may be revoked by the person giving it at any time before it is voted
by delivering to the Secretary of First Shenango at P.O. Box 671, New Castle,
Pennsylvania 16103 on or before the taking of the vote at the First Shenango
Annual Meeting, a written notice of revocation bearing a later date than the
proxy or a later dated proxy relating to the same shares of First Shenango
Common Stock or by attending the First Shenango Annual Meeting and voting in
person. Attendance at the First Shenango Annual Meeting will not in itself
constitute the revocation of a proxy.

         If any other matters are properly presented at the First Shenango
Annual Meeting for consideration, the persons named in the First Shenango Proxy
or acting thereunder will have discretion to vote on such matters in accordance
with their best judgment. As of the date hereof, the First Shenango Board knows
of no such other matters.

         In addition to solicitation by mail, directors, officers, and employees
of First Shenango, who will not be specifically compensated for such services,
may solicit proxies from the stockholders of First Shenango, personally or by
telephone, telegram or other forms of communication. Brokerage houses, nominees,
fiduciaries and other custodians will be requested to forward soliciting
materials to beneficial owners and will be reimbursed for their reasonable
expenses incurred in sending proxy material to beneficial owners. In addition,
First Shenango has engaged Corporate Investor Communications, Inc. ("Corporate
Investor") to assist First Shenango in distributing proxy materials and
contacting record and beneficial owners of First Shenango Common Stock. First
Shenango has agreed to pay Corporate Investor $3,000 plus out-of-pocket expenses
for its services to be rendered on behalf of First Shenango. First Shenango will
bear its own expenses in connection with the solicitation of proxies for the
First Shenango Annual Meeting. See "The Merger--Expenses."

         HOLDERS OF FIRST SHENANGO COMMON STOCK ARE REQUESTED TO COMPLETE, DATE
AND SIGN THE ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED
POSTAGE-PAID ENVELOPE.

         HOLDERS OF FIRST SHENANGO COMMON STOCK SHOULD NOT FORWARD STOCK
CERTIFICATES WITH THEIR PROXY CARDS.

         Voting Securities and Certain Holders Thereof. The following table sets
forth, as of May 4, 1998, certain information as to (i) those persons who were
known by management to be beneficial owners of more than 5% of the outstanding  
shares of First Shenango Common Stock, and (ii) the shares of First Shenango

                                   THE MERGER

         The information below includes a summary of the material terms of the
Merger Agreement, which is qualified in its entirety by reference to the full
text of the Merger Agreement, which is attached hereto as Appendix I and
incorporated by reference herein. All shareholders are urged to read the Merger
Agreement in its entirety.

GENERAL

         Pursuant to the Merger Agreement, First Shenango will be merged with
and into FirstFederal in accordance with the Ohio General Corporation Law and
the Pennsylvania Business Corporation Law, with FirstFederal being the surviving
entity (the "Merger"). On the closing date of the Merger, FirstFederal and First
Shenango will file a certificate of merger with the Secretary of State of Ohio
and articles of merger with the Department of State of the Commonwealth of
Pennsylvania. The Merger will become effective at the time of such filings.

         At the Effective Time, each outstanding share of First Shenango Common
Stock (other than shares held by holders who perfect dissenters' rights) will be
converted into the right to receive 1.143 shares of FirstFederal Common Stock,
subject to adjustment as provided in the Merger Agreement. See "--Merger
Consideration." Each shareholder of First Shenango will then be entitled to
exchange First Shenango Common Stock certificates for FirstFederal Common Stock
certificates and thereupon cease to be a shareholder of First Shenango, and the
separate existence and corporate organization of First Shenango shall cease.

         FirstFederal intends to operate New Castle Bank, currently a wholly
owned subsidiary of First Shenango, as an autonomous, wholly owned subsidiary of
FirstFederal after the Merger.

BACKGROUND OF THE MERGER

         First Shenango is a unitary savings and loan holding company that was
incorporated in December 1992 under the laws of the Commonwealth of Pennsylvania
for the purpose of acquiring all of the issued and outstanding capital stock of
New Castle Bank. This acquisition occurred in April 1993 at the same time New
Castle Bank converted from a mutual to a stock institution, and sold all of its
outstanding capital stock to First Shenango. First Shenango directs and plans
the activities of New Castle Bank, First Shenango's primary asset.

         New Castle Bank is a federally chartered capital stock savings bank
headquartered in New Castle, Pennsylvania, with three branch offices located
within the surrounding townships. New Castle Bank is a community oriented, full
service retail savings institution offering traditional mortgage loan products
as well as multi-family, commercial real estate, consumer and commercial
business loans. New Castle Bank's deposits are insured up to the maximum
allowable amount by the FDIC.

         In connection with its normal strategic planning process, First
Shenango periodically reviews its strategic business alternatives, devoting
particular attention to the continuing consolidation and increasing competition
in the banking and financial services industries in the western Pennsylvania
market and the future plans of First Shenango to compete in this market. This
regional market is home to several large, regional commercial banking entities,
and the banking market in this area in particular has been subject to
significant consolidation in recent years. As a result,

                                       22


<PAGE>   34



competition in the local banking and financial services industries has
intensified, especially for smaller institutions like First Shenango.

         In October 1997, the First Shenango Board retained McDonald & Company
to provide financial advisory assistance, including the evaluation of a possible
sale or merger transaction. McDonald & Company undertook to provide to the First
Shenango Board an overview of the market for bank and thrift mergers, an
assessment of comparable acquisitions and mergers as well as other market
information concerning the valuation of banks and thrifts, the ability of
potential acquirors to consummate a transaction with First Shenango and an
overview of the process to be followed pursuant to a strategic merger or
acquisition transaction. On November 25, 1997, McDonald & Company presented to
the First Shenango Board the results of its analysis. At that meeting at which
counsel for First Shenango was present, the First Shenango Board requested that
McDonald & Company perform a targeted market survey of potential merger partners
to ascertain the level of interest in pursuing a transaction with First
Shenango. McDonald & Company, with the help of senior management of First
Shenango, sent descriptive information to targeted possible merger partners
during the first week of December 1997.

         During the third week of December 1997, McDonald & Company received
non-binding indications of interest from three institutions, including
FirstFederal. The First Shenango Board met with McDonald & Company and senior
management on December 22, 1997 to consider the indications of interest from the
three institutions. McDonald & Company reviewed with the First Shenango Board
the tentative proposals of the three bidders. McDonald & Company also briefed
the First Shenango Board on the general climate of the merger/acquisitions
marketplace and reported on all contacts with other financial institutions by
McDonald & Company acting on First Shenango's behalf. At that meeting, following
its review of the three indications of interest and its belief that the two
highest indications, including FirstFederal's, were substantially more
advantageous than the third indication of interest, the First Shenango Board
directed McDonald & Company and senior management to invite the two highest
bidders to perform a formal due diligence review of First Shenango.

         Following such due diligence review, McDonald & Company requested and
received formal written offers on January 20, 1998 and provided members of the
First Shenango Board and senior management with copies of the written offers.
The First Shenango Board met with McDonald & Company on January 21, 1998, with
First Shenango counsel present by teleconference, to discuss and compare the two
offers and differences between the offers and the indications of interest.
Throughout the foregoing process, management advised and informed the First
Shenango Board of developments and was directed by the First Shenango Board to
pursue discussions. The First Shenango Board determined to give each bidder an
opportunity to address specific concerns of the First Shenango Board and
authorized McDonald & Company to negotiate and request a final bid from each of
the two institutions. The final offers were received from each institution on
January 22, 1998 and the First Shenango Board met again with McDonald & Company,
with First Shenango counsel present by teleconference, at which meeting further
analysis of the offers and differences from the prior offers were discussed. As
part of this analysis, the financial consideration of the two offers was
discussed, including the indicated present dollar value of the two offers. The
future value of the consideration was also discussed because the consideration
was not to be in the form of cash but in the form of the stock of the successful
bidder. The analysis indicated that the bid from FirstFederal would provide
superior value to the holders of the First Shenango Common Stock. At this
meeting, it was determined by the First Shenango Board to pursue the offer from
FirstFederal and the First Shenango Board authorized management, counsel and
McDonald & Company to begin negotiating a definitive agreement with
FirstFederal.

         Following this meeting, First Shenango and FirstFederal continued to
discuss the other terms of the proposed Merger, including the treatment of First
Shenango stock options and other employee benefit plans, the termination
provisions, and issues relating to the management and operations of New Castle
Bank following the Merger. During this period, First Shenango, FirstFederal, and
their respective legal counsel and financial advisors conducted and continued
reciprocal due diligence analyses. Also following this meeting, senior
management of both institutions, with the assistance of McDonald & Company and
First Shenango counsel, negotiated a form of definitive merger agreement. Draft
copies of various drafts of the proposed agreement were distributed to the
members of the First Shenango Board for their review.

                                       23


<PAGE>   35



         On February 6, 1998, the First Shenango Board met with McDonald &
Company and First Shenango's counsel to discuss and review the final proposal,
including the form of agreement which had previously been distributed to the
First Shenango Board and learned from McDonald & Company that, in the opinion of
McDonald & Company as of such date, the Exchange Ratio was fair to First
Shenango's shareholders from a financial point of view.

         On February 6, 1998, at that same meeting of the First Shenango Board,
the First Shenango Board reviewed the reasons for, and the potential benefits of
the Merger; First Shenango's legal counsel reviewed the terms of the Merger
Agreement, related agreements and the transactions contemplated thereby;
management summarized its findings from its examination of the operations and
premises of FirstFederal and its subsidiaries; the independent accountants for
First Shenango presented their views concerning FirstFederal and its
subsidiaries and the accounting methods employed by FirstFederal; and McDonald &
Company made a presentation regarding the financial terms of the Merger
Agreement and the fairness, from a financial point of view, of the Exchange
Ratio to holders of First Shenango Common Stock as of such date. After a
thorough discussion and consideration of the factors discussed below under
"First Shenango's Reasons for the Merger," the First Shenango Board unanimously
approved the Merger Agreement and the transactions contemplated thereby, and
authorized the execution of the Merger Agreement. The Merger Agreement was
entered into on February 6, 1998.

REASONS FOR THE MERGER

         FirstFederal's Reasons for the Merger. The FirstFederal Board believes
the Merger will continue FirstFederal's strategic plan to be a super-community
bank. It is expected that FirstFederal will benefit from First Shenango's strong
capital position and its attractive funding base. The combined company's
financial strength and the potential for cross marketing products and services
to customers of both entities is expected to produce positive results. The
Merger will allow FirstFederal a natural market extension into Lawrence County,
Pennsylvania from its existing franchise in Ohio and will allow future expansion
in a market that is culturally and demographically similar to FirstFederal's
existing market. In addition, the FirstFederal Board also considers that First
Shenango is an institution that has managed business risks well and possesses a
commitment to providing exceptional customer service. The similarities in
marketing and operating philosophy are expected to facilitate the post-Merger
operations.

         First Shenango's Reasons for the Merger. In reaching its decision to
approve the Merger Agreement, the First Shenango Board considered a number of
factors. The First Shenango Board did not assign any relative or specific
weights to the factors considered. Among other things, the First Shenango Board
considered: (i) the Merger consideration in relation to the book value, assets
and earnings of First Shenango; (ii) information concerning the financial
condition, results of operations and prospects of First Shenango and
FirstFederal, including the return on assets and return on equity of the
respective companies; (iii) the financial terms of other recent business
combinations in the banking industry; and (iv) the opinion of McDonald & Company
as to the fairness of the Exchange Ratio, as of such date, to First Shenango
shareholders from a financial point of view.

         The First Shenango Board believes that the terms of the Merger
Agreement, which are the product of arms-length negotiations between
FirstFederal and First Shenango, are in the best interest of First Shenango and
its shareholders. In the course of reaching its determination, the First
Shenango Board consulted with legal counsel with respect to its legal duties,
the terms of the Merger Agreement and the issues related thereto; with its
financial advisor with respect to the financial aspects of the transaction; and
with senior management regarding, among other things, operational matters.

         In reaching its determination to approve the Merger Agreement, the
First Shenango Board also considered the following factors:

         (a) The First Shenango Board analyzed information with respect to the
financial condition, results of operations, businesses and prospects of First
Shenango and FirstFederal.

                                       24


<PAGE>   36



         (b) The First Shenango Board considered the written opinion of McDonald
& Company that, as of February 6, 1998, the Exchange Ratio was fair to First
Shenango shareholders from a financial point of view. See "--Opinion of First
Shenango's Financial Advisor."

         (c) The First Shenango Board considered the current operating
environment, including, but not limited to, the continuing consolidation and
increasing competition in the banking and financial services industries, the
prospect for further changes in these industries, and the importance of being
able to capitalize on developing opportunities in these industries. This
information had been periodically reviewed by the First Shenango Board at its
regular board meetings and was also discussed between the First Shenango Board
and First Shenango's various advisors.

         (d) The First Shenango Board considered the other terms of the Merger
Agreement and exhibits, including the tax-free nature of the transaction.

         (e) The First Shenango Board considered the detailed financial analyses
and other information with respect to First Shenango and FirstFederal discussed
by McDonald & Company, as well as the First Shenango Board's knowledge of First
Shenango, FirstFederal and their respective businesses. In this regard, the
latest publicly-available financial and other information for First Shenango and
FirstFederal were analyzed, including a comparison to publicly-available
financial and other information for other similar institutions.

         (f) The First Shenango Board considered the value of First Shenango
Common Stock if First Shenango continued as a stand-alone entity compared to the
effect of First Shenango combining with FirstFederal in light of the factors
summarized above and the current economic and financial environment, including,
but not limited to, other possible strategic alternatives, the results of the
contacts and discussions between First Shenango and its financial advisor and
various third parties and the belief of the First Shenango Board and management
that the Merger offered the best transaction available to First Shenango and its
shareholders and also allowed for New Castle Bank to remain as a separate entity
and continue to provide service to the community.

         (g) The First Shenango Board considered the likelihood of the Merger
being approved by the appropriate regulatory authorities, including factors such
as market share analysis, FirstFederal's Community Reinvestment Act rating and
the estimated pro forma financial impact of the Merger on FirstFederal.

         (h) The First Shenango Board considered the effect of the Merger on
First Shenango's employees, customers and the communities it serves.

         The foregoing discussion of the information and factors considered by
the First Shenango Board is not intended to be exhaustive, but constitutes the
material factors considered by the First Shenango Board. In reaching its
determination to approve and recommend the Merger Agreement, the First Shenango
Board did not assign any relative or specific weights to the foregoing factors,
and individual directors may have weighted factors differently. After
deliberating with respect to the Merger and the other transactions contemplated
by the Merger Agreement, considering, among other things, the matters discussed
above and the opinion of McDonald & Company referred to above, the First
Shenango Board approved and adopted the Merger Agreement and the transactions
contemplated thereby as being in the best interests of First Shenango and its
shareholders.

MERGER CONSIDERATION

         Subject to the terms, conditions and procedures set forth in the Merger
Agreement, each share of First Shenango Common Stock issued and outstanding
immediately prior to the Merger (other than shares held by holders who perfect
dissenters' rights) will be converted into the right to receive 1.143 shares
(the "Exchange Ratio") of FirstFederal Common Stock, subject to adjustment as
described below. The Exchange Ratio was determined through arm's-length
negotiations between FirstFederal and First Shenango. First Shenango was advised
during these negotiations by its financial advisor, McDonald & Company.

                                       25


<PAGE>   37
         Each share of FirstFederal Common Stock issued and outstanding at the
Effective Time will remain outstanding and unchanged as a result of the Merger.
No fractional shares of FirstFederal Common Stock will be issued in the Merger,
and First Shenango shareholders who otherwise would be entitled to receive a
fractional share of FirstFederal Common Stock will receive a cash payment in
lieu thereof. See "--Fractional Shares."

         As noted above, the number of shares of FirstFederal Common Stock to be
received for each share of First Shenango Common Stock has been fixed at 1.143.
The Merger Agreement provides that in the event of a change in the number of
shares of FirstFederal Common Stock between the date of the Merger Agreement and
the Effective Time by reason of any reclassification, recapitalization,
split-up, combination or exchange of shares, or by stock dividend or stock split
thereon an appropriate adjustment shall be made to the Exchange Ratio. Assuming
the occurrence of the five-for-four stock split in the form of a stock dividend
that has been declared by FirstFederal, payable on May 22, 1998 to holders of
record of FirstFederal Common Stock as of May 4, 1998, the Exchange Ratio at the
Effective Time will be 1.42875. Based on the last reported sale price for
FirstFederal Common Stock on the Nasdaq Stock Market on May 4, 1998 ($41.25 per
share), the value of 1.143 shares of FirstFederal Common Stock as of that date
would have been approximately $47.15. The market value of FirstFederal Common
Stock to be received in the Merger is subject to fluctuation. Fluctuations in
the market price of FirstFederal Common Stock would generally result in an
increase or decrease in the value of the consideration to be received by First
Shenango shareholders in the Merger. An increase in the market value of
FirstFederal Common Stock would generally increase the value of the
consideration to be received by First Shenango shareholders in the Merger. A
decrease in the market value of FirstFederal Common Stock would generally have
the opposite effect.

FRACTIONAL SHARES

         No certificates representing fractional shares of FirstFederal Common
Stock will be issued upon the surrender for exchange of certificates
representing First Shenango Common Stock, and such fractional share interests
will not entitle the owner thereof to vote or receive dividends or any rights of
a shareholder of FirstFederal. Each shareholder of First Shenango who otherwise
would be entitled to a fractional share of FirstFederal Common Stock in the
Merger will receive a cash payment in lieu thereof in an amount determined by
multiplying the fractional share interest to which shareholder would otherwise
be entitled by the average of the closing bid and ask prices of FirstFederal
Common Stock as reported on the Nasdaq National Market during the ten
consecutive trading days ending on the third trading day prior to the Closing
Date.

TREATMENT OF FIRST SHENANGO STOCK OPTIONS

         Each option to purchase shares of First Shenango Common Stock
outstanding immediately prior to the Effective Time granted pursuant to the
First Shenango Bancorp, Inc. 1993 Stock Option Plan (the "First Shenango Option
Plan") will, at the Effective Time, be converted into the right to purchase the
number of shares of FirstFederal Common Stock (rounded up to the nearest whole
share) that would have been received by the holder of such option in the Merger
had the option been exercised in full immediately prior to the Effective Time.
The exercise price of each new option will be equal to the exercise price of the
corresponding old option divided by the Exchange Ratio.

OPINION OF FIRSTFEDERAL'S FINANCIAL ADVISOR

         On January 27, 1998, FirstFederal retained Keefe Bruyette to render an
opinion as to the fairness, from a financial point of view, of the Merger to the
shareholders of FirstFederal. Keefe Bruyette was selected to serve as
FirstFederal's financial advisor because Keefe Bruyette is a nationally
recognized investment banking firm with substantial experience in transactions
similar to the Merger and is familiar with FirstFederal and its business. As
part of its investment banking business, Keefe Bruyette is continually engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions.

         Keefe Bruyette's opinion, dated the date of this Joint Proxy
Statement/Prospectus, is directed to the FirstFederal Board and does not
constitute a recommendation to any FirstFederal shareholder as to how such
shareholder should vote at the FirstFederal Annual Meeting with respect to the
Merger Agreement or any other matter related thereto. No limitations were
imposed by the FirstFederal Board

                                       26

upon Keefe Bruyette with respect to the investigations made or procedures
followed by Keefe Bruyette in rendering its opinion.

         THE FULL TEXT OF KEEFE BRUYETTE'S WRITTEN OPINION DATED AS OF THE DATE
OF THIS JOINT PROXY STATEMENT/PROSPECTUS IS ATTACHED AS APPENDIX II TO THIS
JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THE
DESCRIPTION OF THE OPINION SET FORTH HEREIN IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO APPENDIX II. FIRSTFEDERAL SHAREHOLDERS ARE URGED TO READ THE
OPINION IN ITS ENTIRETY FOR A DESCRIPTION OF THE PROCEDURES FOLLOWED,
ASSUMPTIONS MADE, MATTERS CONSIDERED, AND QUALIFICATIONS AND LIMITATIONS ON THE
REVIEW UNDERTAKEN BY KEEFE BRUYETTE IN CONNECTION THEREWITH.

         In rendering its opinion, Keefe Bruyette reviewed, analyzed and relied
upon the following material relating to the financial and operating condition of
First Shenango and FirstFederal: (i) the Merger Agreement; (ii) Annual Reports
to Shareholders for the three years ended December 31, 1996 for First Shenango
and FirstFederal; (iii) certain interim reports to shareholders of First
Shenango and FirstFederal and Quarterly Reports on Form 10-Q of First Shenango
and FirstFederal and certain other communications from First Shenango and
FirstFederal to their respective shareholders; (iv) other financial information
concerning the businesses and operations of First Shenango and FirstFederal
furnished to Keefe Bruyette by First Shenango and FirstFederal for the purpose
of Keefe Bruyette's analysis, including certain internal financial analyses and
forecasts for First Shenango and FirstFederal prepared by senior management of
First Shenango and FirstFederal; (v) certain publicly available information
concerning the trading of, and the trading market for, the FirstFederal Common
Stock and First Shenango Common Stock; and (vi) certain publicly available
information with respect to banking companies and the nature and terms of
certain other transactions which Keefe Bruyette considered relevant to its
inquiry. Additionally, in connection with its written opinion attached as
Appendix II to this Joint Proxy Statement/Prospectus, Keefe Bruyette reviewed a
draft of this Joint Proxy Statement/Prospectus in substantially the form hereof.
Keefe Bruyette also held discussions with senior management of First Shenango
and FirstFederal concerning their past and current operations, financial
condition and prospects, as well as the results of regulatory examinations.
Keefe Bruyette also considered such financial and other factors as it deemed
appropriate under the circumstances and took into account its assessment of
general economic, market and financial conditions and its experience in similar
transactions, as well as its experience in securities valuation and its
knowledge of banks, bank holding companies and thrift institutions generally.
Keefe Bruyette's opinion was necessarily based upon conditions as they existed
and could be evaluated on the date thereof and the information made available to
Keefe Bruyette through the date thereof.

         In conducting its review and arriving at its opinion, Keefe Bruyette
relied upon and assumed the accuracy and completeness of all of the financial
and other information provided to it or publicly available, and Keefe Bruyette
did not attempt to verify such information independently. Keefe Bruyette relied
upon the managements of First Shenango and FirstFederal as to the reasonableness
and achievability of the financial and operating forecasts (the assumptions and
bases therefor) provided to Keefe Bruyette and assumed that such forecasts
reflected the best available estimates and judgments of such managements and
that such forecasts will be realized in the amounts and in the time periods
estimated by such managements. Keefe Bruyette also assumed, without independent
verification, that the aggregate allowances for loan losses for First Shenango
and FirstFederal are adequate to cover such losses. Keefe Bruyette did not make
or obtain any evaluations or appraisals of the property of First Shenango or
FirstFederal, nor did Keefe Bruyette examine any individual loan credit files.
Keefe Bruyette was informed by FirstFederal, and assumed for purposes of its
opinion, that the Merger would be accounted for as a pooling-of-interests under
generally accepted accounting principles.

         The following is a summary of the material financial analyses employed
by Keefe Bruyette as of February 6, 1998 and confirmed as of the date hereof in
connection with its opinion and does not purport to be a complete description of
all analyses employed by Keefe Bruyette, although all material elements of the
opinion are included in the summary.

         Transaction Summary. Keefe Bruyette calculated the merger consideration
to be paid pursuant to the Exchange Ratio as a multiple of First Shenango's book
value and tangible book value as of December 31, 1997 and earnings per share for
the year ended December 31, 1997. This computation assumed a price per share of
FirstFederal Common Stock of $41.75 (closing price on February 6, 1998) and
Exchange Ratio of 1.143 shares of FirstFederal Common Stock per share of First
Shenango Common Stock. Based upon such assumptions, this analysis

                                       27


<PAGE>   39



indicated First Shenango shareholders would receive shares of FirstFederal
Common Stock worth $47.72 for each share of First Shenango Common Stock held,
and that such an amount would represent a multiple of 2.06 times book value per
share, 2.06 times tangible book value per share and 21.30 times 1997 earnings
per share.

         Contribution Analysis. Keefe Bruyette analyzed the relative
contribution of each of FirstFederal and First Shenango to certain balance sheet
and income statement items, including assets, common equity, deposits and 1997
net income. Keefe Bruyette then compared the relative contribution of such
balance sheet and income statement items with the estimated pro forma ownership
on a fully diluted basis of 24% for First Shenango shareholders based on an
Exchange Ratio of 1.143. The contribution analysis showed that First Shenango
would contribute approximately 21% of the combined assets, 31% of the combined
total equity, 22% of the combined deposits and 23% of the combined 1997 net
income.

         Selected Transaction Analysis. Keefe Bruyette analyzed certain
financial data related to twenty acquisitions of thrift and savings bank holding
companies with assets of between $300 million and $600 million announced from
January 28, 1997 to February 2, 1998 (the "Thrift Acquisitions").

         The following transactions comprised the Thrift Acquisitions: 1855
Bancorp/Sandwich Bancorp, Telebanc Financial/Direct Financial Corp., Citizens
Financial Services/SuburbFed Financial, Sovereign Bancorp/First Home Bancorp,
Alliance Bancorp/Southwest Bancshares, One Valley Bancorp of WV/FFVA Financial
Corp, UST Corp/Somerset Savings Bank, Magna Group/Charter Financial, Mercantile
Bancorp/HomeCorp Inc., Eastern Bank Corp/Emerald Isle Bancorp, First Commercial
Corp/Kemmons Wilson, Commercial Federal/Mid Continent Bancshares, Carolina First
Corp./First SE Financial Corp., Union Planters Corp./Sho-Me Financial, Crestar
Financial/American National Bancorp, Garden State Bankshares/Primary Bank,
Charter One Financial/Haverfield Corp., Webster Financial Corp./Peoples Savings
Financial, CFX Corporation/Community Bankshares and Eagle Financial Corp/MidConn
Bank.

         For the Thrift Acquisitions, Keefe Bruyette calculated an average
multiple of price to the sellers' earnings (trailing twelve months) as 20.42
times compared to a multiple of 21.30 times 1997 earnings per share associated
with the Merger, an average premium to the sellers' stated book value of 196%
compared to a premium of 206% associated with the Merger; and an average premium
to the sellers' tangible book value of 201% compared to a premium of 206%
associated with the Merger.

         Selected Peer Group Analysis. Keefe Bruyette compared the financial
performance and market performance of First Shenango based on various financial
measures of earnings performance, operating efficiency, capital adequacy and
asset quality and various measures of market performance, including market/book
value, price to earnings and dividend yields to those of a group of comparable
holding companies. For purposes of such analysis, the financial information used
by Keefe Bruyette was as of and for the quarter ended December 31, 1997 as
available and the market price information was as of February 6, 1998. The
companies in the peer group were thrift holding companies in Ohio and
Pennsylvania which had total assets ranging from approximately $300 million to
$600 million and included, TF Financial Corporation, First Defiance Financial
Corp., Fidelity Financial of Ohio, Inc., Camco Financial Corporation, Progress
Financial Corporation, PVF Capital Corp., Fidelity Bancorp, Inc., First Keystone
Financial, Inc., Industrial Bancorp, Inc., Harleysville Savings Bank, Winton
Financial Corp., Chester Valley Bancorp, Inc., Glenway Financial Corp., and
Pittsburgh Home Financial Corp.

         Keefe Bruyette's analysis showed the following concerning First
Shenango's financial performance: that its return on equity on an annualized
basis was 9.02%, compared with an average of 11.01% for the peer group; that its
return on assets on an annualized basis was 1.10%, compared with an average of
 .95% for the group; that its net interest margin on an annualized basis was
3.15%, compared with an average of 3.40%; that its efficiency ratio on an
annualized basis was 45.21%, compared with an average of 57.73%; that its equity
to assets ratio was 12.76%, compared to an average of 9.40%; that its ratio of
nonperforming assets to total loans and other real estate owned was 0.51%,
compared to an average of 0.53%; that its ratio of loan loss reserve to
nonperforming loans was 254%, compared to an average of 225%.

                                       28


<PAGE>   40



         Keefe Bruyette's analysis further showed the following concerning First
Shenango's market performance: that First Shenango's price to earnings multiple
based on 1998 estimated earnings was 15.71 times, compared to an average for the
group of 15.70 times; that First Shenango's price to book value multiple was
1.66 times, compared to a group average of 1.70 times; First Shenango's dividend
yield was 1.56%, compared to an average for the group of 1.59%. For purposes of
the above calculations, 1998 earnings estimates were based upon estimates of
Keefe Bruyette and estimates by a nationally recognized composite earnings
estimate service.

         Other Merger Analysis. Keefe Bruyette reviewed with FirstFederal
management the strategic benefits of the Merger, including the addition of First
Shenango's core deposit base as a source of funding and the addition of First
Shenango's revenues and net income to FirstFederal's banking revenues and net
income. Keefe Bruyette also reviewed the pro forma merger analyses that combined
the 1997 annualized nine months' income statement and September 30, 1997 balance
sheet information for both FirstFederal and First Shenango and FirstFederal's
assumptions regarding the accounting treatment, acquisition adjustments, cost
savings, stock option treatment and other factors used to calculate the pro
forma financial impact that the acquisition would have on certain financial
results of FirstFederal.

         Keefe Bruyette has been retained by the FirstFederal Board as an
independent contractor to act as financial adviser to FirstFederal with respect
to the Merger. Keefe Bruyette as part of its investment banking business, is
continually engaged in the valuation of banking businesses and their securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes. As
specialists in the securities of banking companies, Keefe Bruyette has
experience in, and knowledge of, the valuation of banking enterprises. In the
ordinary course of its business as a broker-dealer, Keefe Bruyette may, from
time to time, purchase securities from, and sell securities to, FirstFederal and
as a market maker in securities Keefe Bruyette may from time to time have a long
or short position in, and buy or sell, debt or equity securities of FirstFederal
for Keefe Bruyette's own account and for the accounts of its customers.

         FirstFederal and Keefe Bruyette have entered into a letter agreement
dated January 27, 1998 relating to the services to be provided by Keefe Bruyette
in connection with the Merger. FirstFederal has agreed to pay Keefe Bruyette's
fees as follows: a cash fee of $25,000 following the signing of the Merger
Agreement, $25,000 upon the mailing of the Joint Proxy Statement/Prospectus
relating to the Merger and $100,000 upon consummation of the Merger. Pursuant to
the Keefe Bruyette engagement agreement, FirstFederal also agreed to reimburse
Keefe Bruyette for reasonable out-of-pocket expenses and disbursements incurred
in connection with its retention and to indemnify Keefe Bruyette against certain
liabilities, including liabilities under the federal securities laws.

OPINION OF FIRST SHENANGO'S FINANCIAL ADVISOR

         First Shenango has retained McDonald & Company to render its opinion
with respect to the fairness, from a financial point of view, of the Exchange
Ratio to the holders of First Shenango Common Stock. McDonald & Company
rendered its oral opinion to the First Shenango Board on February 6, 1998,      
which it subsequently confirmed in writing as of February 6, 1998, that, as of
the date of such opinion, the Exchange Ratio pursuant to the Merger was fair,
from a financial point of view, to the holders of First Shenango Common Stock.

         THE FULL TEXT OF THE OPINION OF MCDONALD & COMPANY, UPDATED AS OF THE
DATE OF THIS JOINT PROXY STATEMENT/PROSPECTUS, WHICH SETS FORTH CERTAIN
ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEWS UNDERTAKEN,
IS ATTACHED AS APPENDIX III TO THIS JOINT PROXY STATEMENT/PROSPECTUS, AND SHOULD
BE READ IN ITS ENTIRETY. THE SUMMARY OF THE OPINION OF MCDONALD & COMPANY SET
FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE OPINION. MCDONALD & COMPANY'S OPINION IS DIRECTED TO THE FIRST
SHENANGO BOARD AND ADDRESSES ONLY THE EXCHANGE RATIO.

         In arriving at its opinion, McDonald & Company reviewed, among other
things, the Merger Agreement together with exhibits and schedules thereto,
certain publicly available information relating to the business, financial
condition and operations of First Shenango and FirstFederal as well as certain
other non-public information, primarily financial in nature, furnished to it by
First Shenango and FirstFederal relating to the respective businesses, earnings,

                                       29


<PAGE>   41



assets and prospects of First Shenango and FirstFederal. McDonald & Company also
held discussions with members of senior management of First Shenango and
FirstFederal concerning their respective businesses, assets, financial forecasts
and prospects. McDonald & Company also reviewed certain publicly available
information concerning the trading of, and the trading market for, First
Shenango Common Stock and FirstFederal Common Stock and certain publicly
available information concerning comparable companies and transactions, all as
set forth in McDonald & Company's opinion.

         McDonald & Company was not engaged to and did not conduct a physical
inspection of any of the assets, properties, or facilities of either First
Shenango or FirstFederal and was not engaged to and has not made, obtained or
been furnished with any independent evaluation or appraisal of any of such
assets, properties, or facilities or any of the liabilities of First Shenango or
FirstFederal. McDonald & Company has assumed and relied, without independent
investigation, upon the accuracy and completeness of the financial and other
information provided to it or publicly available, has relied upon the
representations and warranties of First Shenango and FirstFederal contained in
the Merger Agreement, and has not independently attempted to verify such
information. McDonald & Company has also assumed that all of the conditions to
the Merger as set forth in the Merger Agreement, including the tax-free nature
of the reorganization for federal income tax purposes, would be satisfied and
that the Merger would be consummated on a timely basis in the manner
contemplated by the Merger Agreement. No limitations were imposed by First
Shenango upon McDonald & Company with respect to the scope of McDonald &
Company's investigation, nor were any specific instructions given to McDonald &
Company in connection with its fairness opinion.

         In connection with rendering its opinion dated February 6, 1998, and as
updated as of the date of this Joint Proxy Statement/Prospectus, McDonald &
Company considered a variety of financial analyses, which are summarized below.
McDonald & Company believes that its analyses must be considered as a whole and
that selecting portions of such analyses and of the factors considered by
McDonald & Company without considering all such analyses and factors may create
an incomplete view of the analytical process underlying McDonald & Company's
opinion. In its analyses, McDonald & Company made numerous assumptions with
respect to industry performance, business and economic conditions and other
matters. Any estimates contained in McDonald & Company's analyses are not
necessarily indicative of future results or values, which may be significantly
more or less favorable than such estimates.

         The following is a summary of selected analyses considered by McDonald
& Company and discussed with the First Shenango Board, in connection with
McDonald & Company's opinion dated February 6, 1998 and updated as of the date
hereof: 

         COMPARISON WITH SELECTED COMPANIES. McDonald & Company compared the
financial performance and stock market valuation of FirstFederal with
corresponding data for the following selected companies: 1st Source Corporation,
First Oak Brook Bancshares, Inc., First Western Bancorp, Inc., Mid Am, Inc.,
National Penn Bancshares, Inc., Peoples Bank Corporation of Indianapolis, Prime
Bancorp, Inc., and Trans Financial, Inc. In addition, McDonald & Company
compared the same data of First Shenango with corresponding data for the
following selected companies: Ameriana Bancorp, Enterprise Federal Bancorp,
Inc., Fed One Bancorp, Inc., Fidelity Financial of Ohio, Inc., First Bell
Bancorp, Inc., Laurel Capital Group, Inc., OHSL Financial Corp., Security First
Corp., Wood Bancorp, Inc., and WVS Financial Corporation. At the time, none of
the companies listed above had announced a merger transaction or disclosed an
interest in pursuing a possible merger transaction which would have
significantly affected its stock market valuation.

         CONTRIBUTION ANALYSIS. McDonald & Company analyzed the contribution of
each of First Shenango and FirstFederal to, among other things, the
shareholders' equity and after-tax net income of the pro forma combined company.
This analysis showed that, among other factors, First Shenango would have
contributed 31.9% of the shareholders' equity of the pro forma combined company
as of December 31, 1997 and 24.1% of the pro forma net income for the combined
company for the year ended December 31, 1997, compared to a proposed ownership
of 24.2% of the combined company to be held by holders of First Shenango Common
Stock.

         PRO FORMA MERGER ANALYSIS. McDonald & Company analyzed certain pro
forma effects resulting from the Merger on the pro forma combined company over a
five year period from 1998 through 2002. This analysis, based upon the financial
forecasts of management of First Shenango and FirstFederal and including
estimates of cost savings

                                       30


<PAGE>   42



provided by the management of First Shenango and FirstFederal (but before yield
enhancement and other revenue enhancements), showed approximately 4.7% dilution
for FirstFederal in pro forma earnings per share in 1998 and approximately 3.7%
dilution in pro forma earnings per share in 1999. McDonald & Company also
analyzed the changes in the per share amount of earnings, book value and
indicated dividend represented by one share of First Shenango Common Stock after
the Merger. The analysis was performed on the basis of financial information for
both companies as of and for the years ended December 31, 1995, 1996 and 1997.
The analysis indicated that, among other things, exchanging one share of First
Shenango Common Stock at the Exchange Ratio for shares of FirstFederal Common
Stock on a pro forma basis would have resulted in no change in earnings per
share for each share of First Shenango Common Stock for the year ended December
31, 1997, a 20.3% increase in earnings per share for each share of First
Shenango Common Stock for the year ended December 31, 1998, a 23.7% decrease in
diluted book value per share for each share of First Shenango Common Stock as of
December 31, 1997 and a dividend decrease of 16.2% per share of First Shenango
Common Stock based on FirstFederal's indicated annual dividend rate as of the
date of the opinion.

         ANALYSIS OF SELECTED MERGER TRANSACTIONS. McDonald & Company reviewed
five groups of selected pending thrift acquisition transactions involving (i)
selling thrifts headquartered in Iowa, Illinois, Indiana, Kansas, Kentucky,
Michigan, Minnesota, Missouri, North Dakota, Nebraska, Ohio, Pennsylvania, South
Dakota, West Virginia and Wisconsin, (ii) selling thrifts with total assets
between $200 million and $800 million, (iii) selling thrifts with an equity to
assets ratio of between 10% and 15%, (iv) selling thrifts with a return on
average assets ratio of between 1.00% and 1.50%, and (v) selling thrifts with a
ratio of non-performing assets to total assets of between 0.75% and 1.50%.
McDonald & Company reviewed the ratios of the offer value to stated book value
and tangible book value, the multiple of the last 12 months earnings of the
acquired company (adjusted for the one-time SAIF assessment where applicable),
and the ratio of offer value to assets in each such transaction, and computed
the mean and median ratios and multiples for each group. The calculations
yielded ranges of median ratios of price to stated book value and tangible book
value of 175% to 225%. Median multiples of earnings among the five groups ranged
from 18.9x to 23.1x; and median ratios of offer value to assets ranged from
14.1% to 23.6%. This analysis showed an imputed reference range of $38.50 to
$47.00 per share of First Shenango Common Stock.

         NO COMPANY OR TRANSACTION USED IN THE ABOVE ANALYSES AS A COMPARISON IS
IDENTICAL TO FIRST SHENANGO, FIRSTFEDERAL OR THE MERGER. ACCORDINGLY, AN
ANALYSIS OF THE RESULTS OF THE FOREGOING NECESSARILY INVOLVES COMPLEX
CONSIDERATIONS AND JUDGMENTS CONCERNING THE DIFFERENCES IN FINANCIAL AND
OPERATING CHARACTERISTICS OF THE COMPANIES TO WHICH THEY ARE BEING COMPARED.
MATHEMATICAL ANALYSIS (SUCH AS DETERMINING THE MEAN OR MEDIAN) IS NOT, IN
ITSELF, A MEANINGFUL METHOD OF USING COMPARABLE COMPANY OR COMPARABLE
TRANSACTION DATA.

         DISCOUNTED CASH FLOW ANALYSIS. Using discounted cash flow analysis,
McDonald & Company estimated the present value of the future streams of
after-tax cash flows that First Shenango could produce over a five year period
from 1998 through 2002, under various assumptions, based upon First Shenango's
management forecasts. McDonald & Company then estimated the terminal value of
First Shenango after the five year period by applying an estimated perpetual
growth rate to the sixth year's projected after-tax cash flow and then applied
to this value multiples ranging from 10.0x to 16.7x. The five year cash flow
streams and terminal values were then discounted to present values using
different discount rates chosen to reflect different assumptions regarding the
estimated required rates of return of prospective buyers of First Shenango. On
the basis of such varying assumptions, this discounted cash flow analysis
indicated a reference range of $28.72 to $45.10 per share of First Shenango
Common Stock. This analysis was based upon First Shenango and FirstFederal
management's forecasts including variations and assumptions made by McDonald &
Company, which included adjustments to reflect the anticipated effects of
potential merger-related cost savings estimated by First Shenango and
FirstFederal (but before yield enhancement and other revenue enhancements).
Management's forecasts are based upon many factors and assumptions, many of
which are beyond the control of First Shenango or FirstFederal. As indicated
above, this analysis is not necessarily indicative of actual values or actual
future results and does not purport to reflect the prices at which any
securities may trade at the present time or at any time in the future.

         OTHER ANALYSIS. In addition to performing the analyses summarized
above, McDonald & Company also considered its analysis of the general market for
bank and thrift mergers, First Shenango's relative share of the deposit market
that it serves and the general economic conditions and prospects of those
markets.

                                       31

         In performing its analyses, McDonald & Company made numerous
assumptions with respect to industry performance, general business and economic
conditions and other matters. The analyses performed by McDonald & Company are
not necessarily indicative of actual values, which may be significantly more or
less favorable than the values suggested by such analyses. Such analyses were
prepared solely as part of McDonald & Company's opinion.

         The term "fair from a financial point of view" is a standard phrase
contained in investment banking fairness opinions and refers to the fact that
McDonald & Company's opinion as to the fairness of the Exchange Ratio is
addressed solely to the financial attributes of the Exchange Ratio. The analyses
do not purport to be appraisals or to reflect the prices at which a company
might actually be sold. In addition, as described above, McDonald & Company's
opinion was one of many factors taken into consideration by the First Shenango
Board in making its determination to approve the Merger Agreement. Consequently,
the McDonald & Company analyses described above should not be viewed as
determinative of the First Shenango Board's conclusions with respect to the
value of First Shenango or of the decision of the First Shenango Board to agree
to the Exchange Ratio.

         McDonald & Company's opinion is based on economic and market conditions
and other circumstances existing on, and information made available as of, the
date of the opinion. In addition, the opinion does not address the underlying
business decision to effect the Merger or any other terms of the Merger.
McDonald & Company's opinion does not represent its opinion as to what the value
of First Shenango Common Stock or FirstFederal Common Stock may be at the
Closing Date.

         In connection with its opinion dated as of the date of this Joint Proxy
Statement/Prospectus, McDonald & Company performed procedures to update certain
of its analyses and reviewed the assumptions on which such analyses were based
and the factors considered herewith.

         McDonald & Company, as part of its investment banking business, is
customarily engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. McDonald & Company has
extensive experience with the valuation of financial institutions. The First
Shenango Board selected McDonald & Company as First Shenango's financial advisor
because of McDonald & Company's industry expertise with respect to financial
institutions and because of its substantial experience in transactions similar
to the Merger. McDonald & Company is not affiliated with either First Shenango
or FirstFederal.

         In the ordinary course of business, McDonald & Company makes a market
in FirstFederal Common Stock and First Shenango Common Stock and may actively
trade securities of FirstFederal or First Shenango for its own account and for
the accounts of its customers. At any time and from time to time, McDonald &
Company may hold a short or long position in such securities. In addition,
McDonald & Company has provided investment banking services to FirstFederal in
the past, and may provide such services to FirstFederal in the future. McDonald
& Company has received customary fees for its investment banking services.

         For its services as financial advisor, First Shenango has paid McDonald
& Company a fee of $75,000 upon rendering of the oral opinion. Assuming the
consummation of the Merger and based upon the value of the Merger assuming a
per share merger price of $47.15, additional fees equal to approximately
$950,000 would be payable to McDonald & Company upon consummation of the
Merger. First Shenango has also agreed to reimburse McDonald & Company for its  
reasonable out-of-pocket expenses and to indemnify McDonald & Company against
certain liabilities, including certain liabilities under federal securities

EFFECTIVE TIME AND CLOSING DATE

         The Merger will become effective at the time and on the date of the
filing of a certificate of merger with the Secretary of State of Ohio and
articles of merger with the Department of State of the Commonwealth of
Pennsylvania (the "Effective Time"). Consummation of the Merger will occur only
after the receipt of all requisite regulatory approvals, the approval and
adoption of the Merger Agreement by the requisite vote of First Shenango's and
FirstFederal's shareholders and the satisfaction or waiver of all other
conditions to the Merger. Under the Merger

                                       32


<PAGE>   44



Agreement, the closing of the Merger is to occur on or before August 31, 1998,
or as promptly as possible after regulatory approval is received, but in no
event later than December 31, 1998 (the "Closing Date").

DISSENTERS' RIGHTS

         Each holder of First Shenango Common Stock has the right to dissent
from the Merger and receive the fair value of his or her shares of First
Shenango Common Stock in cash by following the procedures set forth in
Subchapter D of Chapter 15 of the Pennsylvania Business Corporation Law, a copy
of which is attached as Appendix IV to this Joint Proxy Statement/Prospectus. A
First Shenango shareholder who wishes to dissent from the Merger must (i) file
with First Shenango, prior to the vote on the Merger Agreement at the First
Shenango Annual Meeting, written notice of his or her intent to demand payment
of the fair value of his or her shares if the Merger is consummated, (ii) not
effect any change in the beneficial ownership of his or her shares from the date
of filing such notice through the Effective Date of the Merger and (iii) not
vote for the Merger Agreement. Failure to satisfy any of these requirements will
result in forfeiture of dissenter rights. Neither a proxy nor a vote against the
Merger Agreement will satisfy the written notice requirement described in clause
(i) above.

         If the Merger Agreement is approved by the First Shenango shareholders,
First Shenango will mail written notice to all First Shenango shareholders who
gave notice of their intent to demand payment of the fair value of their shares
and who refrained from voting for approval of the Merger Agreement. Such notice
will state when and where demand for payment must be made and certificates for
shares deposited in order to obtain payment (not less than 30 days after the
mailing of the notice by First Shenango). A First Shenango shareholder who fails
to timely demand payment or deposit certificates will forfeit any rights to
receive payment of the fair value of his or her shares.

         Within 60 days after the date set for demanding payment and depositing
certificates, if the Merger has not been consummated, First Shenango must return
any certificates that have been deposited. First Shenango may then send a new
notice demanding payment and depositing of certificates. Promptly after
consummation of the Merger, or upon timely receipt of demand for payment if the
Merger has already been consummated, First Shenango shall either remit to
dissenters who have made demand and deposited their certificates, the amount
that First Shenango estimates to be the fair value of the shares, or provide
written notice that no payment will be made at that point. Such remittance or
notice must be accompanied by (i) the balance sheet and income statement of
First Shenango for the fiscal year ended December 31, 1997 together with the
latest available interim financial statements, if any; (ii) a statement of First
Shenango's estimate of the fair value of the shares; and (iii) notice of the
right of the dissenter to demand payment or supplemental payment, as the case
may be.

         If First Shenango notifies dissenters of its estimate of the fair value
of their shares without remitting such amount or remits payment of its estimate
of the fair value of the shares and a dissenter believes the amount stated or
remitted is less than the fair value of his or her shares, he or she may send to
First Shenango his or her own estimate of the fair value of the shares. Such
estimate must be filed with First Shenango within 30 days after the mailing by
First Shenango of its remittance or notice.

         Within 60 days after the latest of (i) consummation of the Merger; (ii)
timely receipt of demands for payments or (iii) timely receipts of any
estimates, as described in the preceding paragraph, if any demands for payment
remain unsettled, First Shenango may file in a court of competent jurisdiction
an application for relief requesting that the fair value of the shares be
determined by the court. If First Shenango fails to timely file the application,
any First Shenango shareholder who made a demand for payment and who has not
already settled his claim against First Shenango may do so in the name of First
Shenango at any time within 30 days after the expiration of the 60-day period.
If a dissenting shareholder does not file an application within the 30-day
period, each dissenting shareholder will be paid First Shenango's estimate of
the fair value of the shares, and may bring an action to recover any unpaid
amounts.

EXCHANGE OF CERTIFICATES

         At and after the Effective Time, each holder of a certificate or
certificates representing outstanding shares of First Shenango Common Stock (a
"First Shenango Certificate") may surrender such First Shenango Certificate to
the transfer agent of FirstFederal for cancellation and be entitled upon such
surrender to receive in exchange therefor certificate(s) representing the number
of shares of FirstFederal Common Stock to which such holder is entitled under
the Merger Agreement (a "FirstFederal Certificate") and a check for the amount
of cash to be paid in lieu of any fractional share interests, to which such
holder is entitled. Until so surrendered, each First Shenango Certificate shall
be deemed to represent ownership of the number of shares of FirstFederal Common
Stock into which the shares represented by such First Shenango Certificates have
been converted in the Merger. No dividends or other distributions declared after
the Effective Time with respect to FirstFederal Common Stock will be paid to the
holder of any unsurrendered First Shenango Certificate until the holder
surrenders such First Shenango Certificate. After a holder surrenders a First
Shenango Certificate, the holder will be entitled to receive any dividends or
other distributions, without interest, which theretofore had become payable with
respect to shares of FirstFederal Common Stock represented by such First
Shenango Certificate. After the Effective Time, holders of unsurrendered First
Shenango Certificates will be entitled to vote at any meeting of FirstFederal
shareholders, the number of whole shares of FirstFederal Common Stock
represented by such First Shenango Certificates, provided that no holder of
unsurrendered First Shenango Certificates may vote at any meeting of
FirstFederal shareholders that is held more than 30 days after the Effective
Time. If any FirstFederal Certificate is to be issued in a name other than that
in which the First Shenango Certificate surrendered for exchange is issued, the
First Shenango Certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer. Upon the Effective Time, the stock
transfer books of First Shenango will be closed and no transfer of First
Shenango Common Stock may thereafter be made or recognized.

</TABLE>

         Employment Agreements. It is intended that upon the Effective Date of
the Merger, New Castle Bank will enter into employment agreements with Francis
A. Bonadio and Lonny D. Robinson. The agreement with Mr. Bonadio will have a
term of six months during which time he will continue to serve as Chief
Executive Officer of New Castle Bank with a base annual salary of $175,000.
Such agreement may be renewed at the election of New Castle Bank. In the event
of the termination of Mr. Bonadio's employment as a result of a change in
control of FirstFederal or New Castle Bank, Mr. Bonadio will receive a
severance benefit equal to 299% of his prior 5 year average taxable     
compensation. Mr. Robinson will be offered an employment agreement as
President,

                                       34


<PAGE>   46



Chief Financial Officer and Treasurer of New Castle Bank. Such agreement will
have a term of 3 years and a minimum salary of $100,000 per year. Mr. Robinson
will have a similar severance benefit in the event his employment is terminated
following a change in control of FirstFederal or New Castle Bank.

         Directorships. After the Effective Time, the FirstFederal Board will
appoint Dale R. Perelman, a director of First Shenango, to a newly-created
directorship on the FirstFederal Board for a term to expire at FirstFederal's
1999 Annual Meeting of Shareholders. Following the closing of the Merger,
FirstFederal will appoint R. Joseph Hrach, a director of First Shenango, to the
Board of Directors of Signal Bank for a term expiring at the next annual meeting
of stockholders of Signal Bank. In addition, at the Effective Time, the Board of
Directors of New Castle Bank will appoint to such Board, two individuals
recommended by FirstFederal (and approved by the Board of Directors of New
Castle Bank). See "Management After the Merger."

         Severance Benefits. FirstFederal has agreed in the Merger Agreement to
honor the severance agreements in place for various employees of First Shenango
in the event that their employment is terminated within 24 to 36 months of the
Merger.

         First Shenango will make payments to Mr. Bonadio in connection with
terminating the First Shenango Supplemental Executive Retirement Plan for the
benefit of Mr. Bonadio ("SERP"). The estimated payment of such benefits
previously accrued under the SERP is $120,000.

         Employee Stock Ownership Plan. First Shenango maintains the ESOP for
the exclusive benefit of participating employees. The ESOP will terminate, as of
the date of the Merger, and the ESOP will allocate and distribute plan assets to
plan participants and beneficiaries in accordance with its terms. At December
31, 1997, the estimated benefits payable to Messrs. Bonadio and Robinson are
$264,000 and $140,000, respectively. These ESOP payments will be made in
connection with their interests as participants in the ESOP.

         Restricted Stock. Certain First Shenango directors and officers have
been awarded shares of restricted stock under the First Shenango Management
Stock Bonus Plan. All previously awarded restricted shares have vested. As of
the effective date of the Merger, the Management Stock Bonus Plan will
terminate, and any restricted stock previously awarded to officers and employees
of First Shenango will be converted into shares of FirstFederal Common Stock in
accordance with the terms of the Merger Agreement.

         Indemnification of and Continued Insurance Coverage for First Shenango
Management. Pursuant to the Merger Agreement, FirstFederal has agreed that for a
period of six (6) years following the closing date of the Merger, the Merger
will not affect or diminish any of First Shenango's duties and obligations of
indemnification existing as of the closing date of the Merger in favor of
employees, agents, directors or officers of First Shenango or any of its
subsidiaries arising by virtue of First Shenango's Articles of Incorporation or
Bylaws in the form in effect at the date of the Merger Agreement or arising by
virtue of First Shenango's Articles of Incorporation or Bylaws in the form in
effect at the date of the Merger Agreement or arising by operation of law.
FirstFederal will cause the persons serving as officers and directors of First
Shenango immediately prior to the closing date of the Merger to be covered for a
period of 18 months from the closing date of the Merger by the directors' and
officers' liability insurance policy maintained by First Shenango (provided that
FirstFederal may substitute therefor policies of at least the same coverage and
amounts containing terms and conditions which are not materially less
advantageous than such policy) with respect to acts or omissions occurring prior
to the closing date of the Merger which were committed by such officers and
directors in their capacity as such.

         Additional Option Awards. The Merger Agreement provides that within 90
days after the Effective Time, FirstFederal will award options to purchase
25,000 shares of FirstFederal Common Stock to officers of New Castle Bank
pursuant to FirstFederal's 1997 Omnibus Incentive Plan. The options will be
granted at no cost to the officers, and will have an exercise price per share
equal to the fair market value per share of the FirstFederal Common Stock at the
time of grant. Such awards will be determined based upon the recommendation of
New Castle Bank's Board of Directors, as approved by the FirstFederal Board.

First Shenango; (iv) approval of the Merger Agreement by the shareholders of
First Shenango and all other necessary corporate actions relating to the Merger
Agreement have been taken; (v) the obtainment by First Shenango of all necessary
third party consents; (vi) the receipt by FirstFederal of a legal opinion of
Malizia, Spidi, Sloane & Fisch, P.C., counsel to First Shenango, as to certain
matters relating to First Shenango; (vii) the failure by FirstFederal, in
conducting its due diligence investigation of First Shenango, to discover any
material misrepresentation or breach of warranty not previously disclosed to
FirstFederal that would have a Material Adverse Effect on First Shenango, (viii)
all regulatory approvals required or deemed necessary shall have been obtained
and the Registration Statement shall have been declared effective by the SEC;
(ix) the receipt by FirstFederal of a letter from its independent public

Shenango's independent public accountants with respect to certain financial

Directors of New Castle Bank by such Board of two individuals recommended by

to the effect that all conditions precedent to FirstFederal's performance have
been met or waived and all action required to be taken by First Shenango have
been taken; (xiii) the receipt by FirstFederal of the fairness opinion of Keefe
Bruyette, a copy of which is attached hereto as Appendix II; and (xiv) certain
other documentation certifying payment by First Shenango of all taxes and other
payments due the Commonwealth of Pennsylvania and the rent roll of all leased
real properties of which First Shenango is the lessor.

         The obligations of First Shenango under the Merger Agreement are
subject to the satisfaction or waiver prior to the closing of the Merger of the
following conditions: (i) the representations and warranties of FirstFederal in
the Merger Agreement are true in all material respects on and as of the Closing
Date (as though made on the Closing Date), except for breaches which would not

         There can be no assurance that the conditions to each party's
obligations under the Merger Agreement will be satisfied or waived. In the event
the conditions to either party's obligations have not been satisfied or waived,
the other party may elect to terminate the Merger Agreement after regulatory
approval of the Merger is obtained. See

                                       36


<PAGE>   48



"--Waiver and Amendment; Termination." The above summary of the conditions to
consummation of the Merger is qualified entirely by the text of the Merger
Agreement, attached hereto as Appendix I.

REGULATORY APPROVALS

         The Merger is subject to the approval of the FRB. FirstFederal filed an
application for approval of the Merger with the FRB on March 31, 1998, and
anticipates receiving such approval during the second quarter of 1998.
There can be no assurance as to the receipt or timing of such approval.

         It is a condition precedent to the consummation of the Merger that all
requisite regulatory approvals be obtained without the imposition of any
condition which, in the reasonable opinion of the FirstFederal Board, so
materially and adversely affects the anticipated economic and business benefits
to FirstFederal as to render consummation of the Merger inadvisable. There can
be no assurance that any such regulatory approval will not contain conditions or
requirements which will cause such approval to fail to satisfy such condition to
FirstFederal's obligation to consummate the Merger.

WAIVER AND AMENDMENT; TERMINATION

         Either party to the Merger Agreement may waive compliance with any
provision of the Merger Agreement where such waiver is executed in writing by
the party making the waiver. The Merger Agreement may be amended by execution of
the amendment in writing by both FirstFederal and First Shenango.

         Except as noted below, the Merger Agreement may be terminated at any
time prior to the Effective Time, whether prior to or after approval and
adoption of the Merger Agreement by First Shenango's and FirstFederal's
shareholders; (i) by the vote of a majority of the Board of Directors of each of
FirstFederal and First Shenango; (ii) by the vote of a majority of the Board of
Directors of either FirstFederal or First Shenango if the Merger shall not have
been consummated on or before October 31, 1998, unless the failure to consummate
the Merger by such date is related to the action or inaction of the regulatory
authorities, and such action or inaction is not directly related to the
terminating party's breach of its representations and warranties as set forth in
the Merger Agreement; (iii) by the vote of a majority of the Board of Directors
of either FirstFederal or First Shenango if any regulatory authority has denied
approval of the Merger and neither First Shenango nor FirstFederal has timely
filed a request for a reconsideration or a petition seeking review of such
order; (iv) at any time before the closing of the Merger, by First Shenango, in
the event of a material misrepresentation or breach of warranty by FirstFederal
or failure by FirstFederal to disclose any other matter, which, in the
aggregate, would have potential pre-tax liability to FirstFederal in excess of
$3,000,000 if FirstFederal fails to cure such defect within 30 days following
notification thereof by First Shenango; (v) at any time before the closing of
the Merger, by FirstFederal, in the event of a material misrepresentation or
breach of warranty by First Shenango or failure by First Shenango to disclose
any other matter which, in the aggregate, would have potential pre-tax liability
to First Shenango of $1,000,000, if First Shenango fails to cure such defect
within 30 days following notification thereof by FirstFederal; (vi) at any time
after December 31, 1998, by First Shenango or FirstFederal if the closing of the
Merger shall not have occurred on or before such date and such failure to
consummate the Merger is not caused by a breach of the Merger Agreement by the
terminating party; (vii) by either party if any bona fide action or proceeding
shall be pending against either party on the Closing Date that could result in
an unfavorable judgment, decree, or order that would prevent or make unlawful
the carrying out of the Merger Agreement; (viii) by FirstFederal after approval
of the Merger by the regulatory authorities is obtained if the conditions
precedent to FirstFederal's obligation to close have not been satisfied or
waived; (ix) by First Shenango after regulatory approval of the Merger is
obtained if the conditions precedent to First Shenango's obligation to close
have not been satisfied or waived; or (x) by First Shenango if (A) the average
of the closing bid and ask price of FirstFederal Common Stock on the Nasdaq
National Market for the ten consecutive trading days ending on the third trading
day prior to the Closing Date is more than 15% lower than the average of the
closing bid and ask price of FirstFederal Common Stock on the Nasdaq National
Market for the ten consecutive trading days ending on the date prior to the date
of the Merger Agreement ($35.40 per share); and (B) the change in the price per
share of FirstFederal Common Stock referred to in clause (A) above exceeds the
change in the value of the SNL Securities National Bank and Thrift Index for the
comparable period by more than .1% (i.e., the change from 359.47).

         Under the Merger Agreement, First Shenango must pay to FirstFederal a
fee of $3,000,000 in the event the Merger is not consummated and certain events
occur. See "The Merger--Break-up Fee" and Section 5.1.13 of the Merger Agreement
attached hereto as Appendix I.

         In the event of termination of the Merger Agreement pursuant to the
provisions described in the preceding paragraphs, the Merger Agreement will
become null and void and there will be no liability or obligation of
FirstFederal or First Shenango thereunder, except that (i) each party will
remain liable to the other for any breach of the Merger Agreement existing at
time of termination and (ii) FirstFederal and First Shenango will remain subject
to the provisions of confidentiality agreements entered into by such parties
prior to execution of the Merger Agreement.

CONDUCT OF BUSINESS PENDING THE MERGER

         First Shenango has agreed that, prior to the Effective Time, it will
conduct its business and will cause its subsidiaries to carry on their
respective businesses and activities diligently and in substantially the same
manner as they previously have been carried out, and will not institute any new
methods of management, accounting or operation that differ materially from
existing methods. The Merger Agreement provides that an increase in borrowings
by First Shenango of up to $55 million from the Federal Home Loan Bank of
Pittsburgh from the amount outstanding at December 31, 1997 shall be deemed to
be in the ordinary course of business. First Shenango has also agreed that it
and its subsidiaries will not, without the prior written consent of
FirstFederal, among other things: (i) amend their respective corporate charters
or bylaws; (ii) issue any shares of capital stock; (iii) issue any warrants,
options or other commitments under which any additional shares of capital stock
may be authorized; (iv) declare or pay any dividend or authorize any stock split
or make any other distribution in respect of their respective capital stock
other than First Shenango's regular quarterly dividend of $.15 per share; (v)
purchase, redeem or otherwise acquire any shares of their respective capital
stock; (vi) except in the ordinary course of business and consistent with past
practice or as otherwise previously disclosed to FirstFederal, (A) grant any
increase in salaries or wages payable to any officer, employee, sales agent or
representative or (B) increase benefits payable under any bonus or pension plan
or other contract or commitment; (vii) enter or agree to enter into any
agreement or transaction in excess of $50,000, or $250,000 in the aggregate, not
in the usual and ordinary course of business; (viii) except as otherwise
previously disclosed to FirstFederal, (A) modify, amend, cancel or terminate any
of its existing contracts, or become obligated to make any capital expenditures
in excess of $50,000, (B) enter into or renew any agreement for services to be
provided to First Shenango or New Castle Bank or permit the automatic renewal of
any such agreement, except any agreement for services having a term of not more
than three months or requiring the expenditure of not more than $25,000, (C)
apply to the appropriate regulatory authorities to establish a new branch office
or expand any existing branch office or (D) acquire or enter into any agreement
to acquire any banking or non-banking company or any branch offices of any such
company.

         In addition, First Shenango has agreed that it and its subsidiaries
will not directly or indirectly discuss with or solicit or initiate from any
person, any proposals or offers relating to the acquisition of a material amount
of the assets or equity securities of First Shenango or New Castle Bank or any
merger or other business combination with First Shenango or New Castle Bank (an
"Acquisition Transaction"), except that (i) First Shenango or New Castle Bank
may negotiate with and provide information to any person or entity that makes an
unsolicited proposal for an Acquisition Transaction if (A) the First Shenango
Board, upon the written advice of counsel, determines in good faith that such
action is necessary for the directors of First Shenango to fulfill their
fiduciary duties to the shareholders of First Shenango and (B) prior to taking
such action, First Shenango provides written notice thereof to FirstFederal and
(ii) the First Shenango Board may, following receipt of a proposal for an
Acquisition Transaction, elect not to make, or if already made, withdraw its
recommendation otherwise required to be made under the Merger Agreement to the
shareholders of First Shenango that the Merger Agreement be approved, if the
First Shenango Board, upon the written advice of counsel, determines in good
faith that such inaction or withdrawal is necessary for the directors of First
Shenango to fulfill their fiduciary duties to the shareholders of First Shenango
and other constituencies under Pennsylvania law.

EXPENSES

         All expenses incurred or to be incurred in connection with the Merger
Agreement and the consummation of the transactions contemplated thereby are to
be paid by the party incurring such expenses except that First Shenango may not
incur any such costs and expenses in excess of $450,000 in the aggregate,
excluding the fee payable to McDonald & Company for the rendering of financial
advisory services.

BREAK-UP FEE

         Under the Merger Agreement, First Shenango must pay to FirstFederal a
fee of $3,000,000 promptly following termination of the Merger Agreement after

         merge with First Shenango, to acquire all or substantially all of First
         Shenango's assets or to engage in a similar transaction.

ACCOUNTING TREATMENT

         FirstFederal intends to account for the Merger under the pooling of
interests method of accounting. Under this method of accounting, the historical
cost basis of the assets and liabilities of FirstFederal and First Shenango will
be combined and carried forward at their previously recorded amounts, and the
shareholders' equity accounts of FirstFederal and First Shenango will be
combined on FirstFederal's consolidated balance sheet. Income and other
financial statements of FirstFederal issued after consummation of the Merger
will be restated retroactively to reflect the consolidated operations of
FirstFederal and First Shenango as if the Merger had taken place prior to the
periods covered by such financial statements.

         FirstFederal and First Shenango have each agreed to take no actions
which would prevent FirstFederal from utilizing the pooling of interests method.
In addition, it is a condition to FirstFederal's obligations under the Merger
Agreement that FirstFederal receive a letter from KPMG Peat Marwick LLP,
FirstFederal's independent public accountants, to the effect that the Merger    
will qualify for pooling of interests accounting treatment. See "--Conditions
to the Merger" and "Resales of FirstFederal Common Stock by Affiliates."

         The pooling of interests method of accounting may not be utilized if
"tainted" shares, as defined by Accounting Principles Board Opinion No. 16,
exceed 10%. FirstFederal and First Shenango repurchased their own shares of
common stock pursuant to stock repurchase programs during the preceding two year
period. FirstFederal's stock purchase plan was rescinded in April 1997 when the
FirstFederal Board did not renew such plan and First Shenango's stock repurchase
plan expired in January 1998. Based on the number of tainted shares as of the
date of the Merger Agreement, FirstFederal might not be able to account for the
Merger under the pooling of interests method if affiliates of First Shenango do
not exercise outstanding options to purchase at least 35,000 shares of First
Shenango Common Stock prior to the Effective Time. Such affiliates have each
entered into written commitments to exercise the options prior to the Effective
Time.

RESALES OF FIRSTFEDERAL COMMON STOCK BY AFFILIATES

         The shares of FirstFederal Common Stock to be issued in the Merger will
be registered under the Securities Act and will be freely transferable under the
Securities Act, except for shares issued to any shareholder who may be deemed to
be an "affiliate" of FirstFederal or First Shenango under the Securities Act as
of the date of the Special Meeting. Affiliates of FirstFederal or First Shenango
may not sell their shares of FirstFederal Common Stock acquired in connection
with the Merger except pursuant to an effective registration statement under the
Securities Act covering such shares or in compliance with Rule 145 under the
Securities Act (with respect to affiliates of First Shenango) or Rule 144 under
the Securities Act (with respect to persons who are or become affiliates of
FirstFederal) or another applicable exemption from the registration requirements
of the Securities Act. Persons who may be deemed to be affiliates of
FirstFederal or First Shenango generally include individuals or entities that
control, are controlled by or under common control with FirstFederal or First
Shenango, and may include certain officers and directors of FirstFederal and
First Shenango as well as certain principal shareholders of FirstFederal and
First Shenango.

         SEC guidelines regarding qualifying for the pooling of interests method
of accounting also limit sales by affiliates of FirstFederal or First Shenango
in the Merger. SEC guidelines indicate that the pooling of interests method of
accounting generally will not be challenged on the basis of sales by affiliates
if they do not dispose of any of the shares of either combining company during
the period beginning 30 days before the Merger and ending when financial results
covering at least 30 days of post-merger operations of the surviving company
have been published.

<PAGE>   52



         FirstFederal and First Shenango have agreed to use their best efforts
to cause each person identified as an affiliate of FirstFederal or First
Shenango to execute a written agreement intended to ensure compliance with the
Securities Act and to ensure that the Merger will qualify for pooling of
interests accounting treatment.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         Set forth below is a discussion of federal income tax consequences of
the Merger to FirstFederal, First Shenango and First Shenango shareholders who
are citizens or residents of the United States. THE FOLLOWING DISCUSSION
CONSTITUTES THE OPINION OF CRITCHFIELD, CRITCHFIELD & JOHNSTON, LTD., COUNSEL TO
FIRSTFEDERAL, AS TO THE MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER,
AS ISSUED AND DELIVERED TO THE FIRSTFEDERAL BOARD. THE DISCUSSION DOES NOT
PURPORT TO BE A COMPLETE ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS
RELEVANT TO A DECISION WHETHER TO VOTE IN FAVOR OF APPROVAL OF THE MERGER
AGREEMENT. FURTHER, THE DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT
MAY BE RELEVANT TO A PARTICULAR FIRST SHENANGO SHAREHOLDER SUBJECT TO SPECIAL
TREATMENT UNDER CERTAIN FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES,
BANKS, INSURANCE COMPANIES, TAXEXEMPT ORGANIZATIONS, NON-UNITED STATES
SHAREHOLDERS AND PERSONS WHO ACQUIRED THEIR SHARES AS COMPENSATION, NOR ANY
CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN
JURISDICTION. THE DISCUSSION IS BASED UPON THE CODE, TREASURY REGULATIONS
THEREUNDER AND ADMINISTRATIVE RULINGS AND COURT DECISIONS AS OF THE DATE HEREOF.
ALL OF THE FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE
CONTINUING VALIDITY OF THIS DISCUSSION.

         HOLDERS OF FIRST SHENANGO COMMON STOCK ARE URGED TO CONSULT THEIR
PERSONAL TAX ADVISERS AS TO THE PARTICULAR EFFECT OF THEIR OWN PARTICULAR FACTS
AND CIRCUMSTANCES ON THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO THEM,
AND ALSO TO THE EFFECT OF ANY STATE, LOCAL, FOREIGN AND OTHER FEDERAL TAX LAWS.

         Under current federal income tax law, and assuming that the Merger is
consummated in the manner set forth in the Merger Agreement, the following
material federal income tax consequences would result:

         (i) the Merger would qualify as a reorganization under Section 368(a)
         of the Code;

         (ii) no gain or loss would be recognized by FirstFederal or First
         Shenango by reason of the Merger;

         (iii) no gain or loss would be recognized by any First Shenango
         shareholder upon the exchange of First Shenango Common Stock solely for
         FirstFederal Common Stock in the Merger (see items (vi) and (vii) below
         regarding the tax treatment with respect to the receipt of cash in lieu
         of a fractional share of FirstFederal Common Stock or the receipt of
         cash in connection with the exercise of dissenter rights);

         (iv) the aggregate tax basis of the FirstFederal Common Stock received
         by each shareholder of First Shenango who exchanged First Shenango
         Common Stock for FirstFederal Common Stock in the Merger would be the
         same as the aggregate tax basis of the First Shenango Common Stock
         surrendered in exchange therefor (subject to any adjustments required
         as the result of receipt of cash in lieu of a fractional share of
         FirstFederal Common Stock);

         (v) the holding period of the shares of FirstFederal Common Stock
         received by a First Shenango shareholder in the Merger would include
         the holding period of the First Shenango Common Stock surrendered in
         exchange therefor (provided that such shares of First Shenango Common
         Stock were held as a capital asset by such shareholder at the Effective
         Time);

         (vi) cash received in the Merger by a First Shenango shareholder in
         lieu of a fractional share interest of FirstFederal Common Stock would
         be treated as having been received as a distribution in full payment in
         exchange for the fractional share interest of FirstFederal Common Stock
         which such shareholder would otherwise be entitled to receive, and
         would qualify as capital gain or loss (assuming the First Shenango

                                       41


<PAGE>   53



         Common Stock surrendered in exchange therefor were held as a capital
         asset by such shareholder at the Effective Time); and

         (vii) a First Shenango shareholder who received only cash as a result
         of the exercise of dissenter rights would realize gain or loss for
         federal income tax purposes (determined separately as to each block of
         First Shenango Common Stock exchanged) in an amount equal to the
         difference between (x) the amount of cash received by such shareholder,
         and (y) such shareholder's tax basis for the shares of First Shenango
         Common Stock surrendered in exchange therefor, provided that the cash
         payment did not have the effect of the distribution of a dividend. Any
         such gain or loss would be recognized for federal income tax purposes
         and would be treated as capital gain or loss. However, if the cash
         payment did have the effect of the distribution of a dividend, the
         amount of taxable income recognized generally would equal the amount of
         cash received; such income generally would be taxable as a dividend and
         no loss (or other recovery of such shareholder's tax basis for the
         shares of First Shenango Common Stock surrendered in the exchange)
         generally would be recognized by such shareholder. The determination of
         whether a cash payment has the effect of the distribution of a dividend
         would be made pursuant to the provisions and limitations of Section 302
         of the Code, taking into account the constructive stock ownership rules
         of Section 318 of the Code.

         The opinion of Critchfield, Critchfield & Johnston, Ltd. is subject to
various assumptions and qualifications, including that the Merger will be
consummated in the manner contemplated by and in accordance with the terms of
the Merger Agreement. Such assumptions and qualifications are set forth in the 
opinion of Critchfield, Critchfield & Johnston, Ltd., which is filed as Exhibit
8 to the Registration Statement. The opinion is based entirely upon the Code,
regulations currently in effect or proposed thereunder, current administrative
rulings and practice and judicial authority, all of which are subject to
change, possibly with retroactive effect.

         No ruling has been or will be requested from the Internal Revenue
Service ("IRS"), including any ruling as to federal income tax consequences of
the Merger to FirstFederal, First Shenango or First Shenango shareholders.
Unlike a ruling from the IRS, an opinion of counsel or independent certified
accountants is not binding on the IRS. There can be no assurance that the IRS
will not take a position contrary to the positions reflected in such opinion or
that such opinion would be upheld by a court if challenged.

NASDAQ LISTING

         FirstFederal Common Stock is currently listed on the Nasdaq National
Market under the symbol "FFSW." If the FirstFederal Name Change Proposal is
approved at the FirstFederal Annual Meeting, the Nasdaq symbol for FirstFederal
Common Stock will change to "SGNL." See "Amendment to FirstFederal's Articles of
Incorporation to Change Name." FirstFederal will submit an application for
listing on the Nasdaq Stock Market the shares of FirstFederal Common Stock to be
issued to the shareholders of First Shenango in the Merger and to be reserved
for issuance pursuant to First Shenango Stock options assumed by FirstFederal in
the Merger.

                           MANAGEMENT AFTER THE MERGER

         It is anticipated that, following consummation of the Merger, the
FirstFederal Board will consist of the current members of such Board and the
executive officers of FirstFederal will be the current executive officers of
FirstFederal, except after the Effective Time, the FirstFederal Board will
appoint Dale R. Perelman, a director of First Shenango, to a newly-created
directorship on the FirstFederal Board for a term to expire at FirstFederal's
1999 Annual Meeting of Shareholders. Following the closing of the Merger,
FirstFederal will appoint R. Joseph Hrach, a director of First Shenango, to the
Board of Directors of Signal Bank for a term expiring at the next annual meeting
of stockholders of Signal Bank. In addition, at the Effective Time, the Board of
Directors of New Castle Bank will appoint to such Board, two individuals
recommended by FirstFederal (and approved by the Board of Directors of New
Castle Bank). It is anticipated that Francis A. Bonadio, the President and Chief
Executive Officer of First Shenango, and Lonny D. Robinson, the Vice President
and Chief Financial Officer of First Shenango, will serve as Chief Executive
Officer and as President, Chief Financial Officer and Treasurer, respectively,
of New Castle Bank following the Merger pursuant to employment
agreements with New Castle Bank to be effective upon the closing of the Merger.

Forma Condensed Combined Statements of Income for each of the years in the
three-year period ended December 31, 1997 present the combined historical
results of operations of FirstFederal and subsidiaries and First Shenango and
subsidiaries as if the Merger had been effective January 1, 1995. Both
FirstFederal's and First Shenango's fiscal years end December 31. Pro forma per

      NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

         Pursuant to the Merger Agreement and consistent with generally accepted
accounting principles, FirstFederal and First Shenango expect that costs
incurred to effect the Merger, which would include transaction costs of the
Merger and costs to combine operations, will be deducted in determining net
income in the period in which they are incurred. Adjustments to conform the
accounting policies of the entities are reflected in these Unaudited Pro Forma
Condensed Combined Financial Statements and are discussed in the following
notes. The pro forma financial statements do not give effect to any cost savings
which may be realized in connection with the consolidation of the respective
operations of FirstFederal and First Shenango.

(1)      Transaction costs of the Merger (primarily investment banker and other
         professional fees) and costs to combine operations are expected to be
         in the $6.45 million to $8.0 million range (the "Expected Range"). The
         Unaudited Pro Forma Condensed Combined Statements of Income do not
         reflect these charges. The Unaudited Pro Forma Condensed Combined
         Statement of Financial Condition reflects these charges at the
         mid-point of the Expected Range ($7.23 million). It is anticipated that
         these charges will be incurred and recognized by FirstFederal and First
         Shenango and substantially paid by the end of 1998. The following table
         provides details of the estimated charges by type of cost:

Additional loan loss allowance for change in collection efforts......                                    1.10 million
Costs to combine operations:
  Employee Stock Ownership Plan termination costs....................                            2.00 to 2.20 million
  Duplicative systems and operating costs............................                            1.00 to 1.50 million
  Other costs incidental to the Merger...............................                            .50 to   .75 million
    Total Merger-related adjustments.................................                            6.45 to 8.00 million
</TABLE>

         FirstFederal has identified three loans in First Shenango's portfolio
         with a total principal balance of $2.8 million at December 31, 1997 for
         which FirstFederal intends to pursue different collection efforts after
         the Merger. Each of the three loans had been previously identified by
         First Shenango as potential problem credits. As a result of the
         intended post-Merger collection efforts, FirstFederal believes an
         additional loan loss allowance of $1.1 million will be necessary as
         reflected in the table above.

(2)      Represents the expected after-tax effect of the pro forma adjustments,
         as described in note (1) above, assuming a federal income tax rate of
         35%. Transaction costs are not deductible for federal income tax
         purposes.

(3)      Represents the expected income tax benefit associated with the pro
         forma adjustments.

(4)      Represents the exercise of options covering 5,000 shares of First
         Shenango Common Stock at $20.75 per share and the exercise of options
         covering 94,339 shares of First Shenango common Stock at $10.00 per
         share which are expected to occur prior to the closing of the Merger
         pursuant to written commitments to exercise executed by the optionees.

(5)      The pro forma combined per share data has been computed based on the
         combined historical income and on the combined weighted average common
         and common equivalent shares outstanding assuming the issuance of 1.143
         shares of FirstFederal Common Stock for each share of First Shenango
         Common Stock based on the Exchange Ratio. Shares assumed to
         be issued in computing the weighted number of common and common
         equivalent shares outstanding used to compute basic per share earnings
         for the years ended December 31, 1997, 1996 and 1995 were 2,269,000,
         2,467,000 and 2,493,000, respectively.

                    DESCRIPTION OF FIRSTFEDERAL COMMON STOCK

GENERAL

         The Articles of Incorporation of FirstFederal (the "FirstFederal
Articles") authorize the issuance by FirstFederal of up to 20,000,000 shares of
FirstFederal Common Stock, par value $1.00 per share, of which 6,756,868 shares
were issued and outstanding as of May 4, 1998. As noted elsewhere herein, at
the First Federal Annual Meeting, FirstFederal shareholders are being asked to
adopt an amendment to the FirstFederal Articles to increase the number of
authorized shares of FirstFederal Common Stock from 20,000,000 to 40,000,000.
See "Amendment to FirstFederal's Articles of Incorporation to Increase
Authorized Shares." The FirstFederal Common Stock is currently quoted on the
Nasdaq National Market under the symbol "FFSW." Provided the FirstFederal Name
Change Proposal is approved at the FirstFederal Annual Meeting (in which case
the name of FirstFederal will change to "Signal Corp"), the Nasdaq symbol for
the FirstFederal Common Stock will change to "SGNL." See "Amendment to
FirstFederal Articles of Incorporation to Change Name." Each share of
FirstFederal Common Stock has the same relative rights and is identical in all
respects with each other share of FirstFederal Common Stock.

DIVIDENDS

         Subject to the rights of the holders of shares of the serial preferred
stock of FirstFederal, holders of the shares of FirstFederal Common Stock are
entitled to receive such dividends as are declared by the FirstFederal Board out
of funds legally available therefor. Unless all prior dividends on
FirstFederal's Series B Preferred Stock have been paid in full, or a sum
sufficient for payment has been reserved (i) no cash dividend or distribution
(other than in shares of FirstFederal Common Stock or other securities ranking
junior to the Series B Preferred Stock) may be declared or paid on the
FirstFederal Common Stock, and (ii) FirstFederal may not purchase, retire or
otherwise acquire any shares of FirstFederal Common Stock. In addition, during
any Extension Period with respect to the FirstFederal Debentures, FirstFederal
may not declare or make any dividends or distributions on its capital stock. See
"Summary-The Parties to the Merger--FirstFederal Financial Services Corp."

         There are various regulatory restrictions on the ability of
FirstFederal to pay dividends, including dividends funded by capital
distributions to FirstFederal from its subsidiaries.

VOTING RIGHTS

         Full voting rights are vested in the holders of FirstFederal Common
Stock, each share being entitled to one vote. Under the Code of Regulations of
FirstFederal (the "FirstFederal Code"), unless otherwise provided in the
FirstFederal Articles or Code or required by law, a majority of the votes cast
by stockholders at a lawful meeting is sufficient to pass on a matter.

PREEMPTIVE RIGHTS

         The holders of FirstFederal Common Stock have no right to purchase or
subscribe for any additional unissued shares or treasury shares of the capital
stock of FirstFederal.

LIQUIDATION RIGHTS

         Subject to the rights of holders of the serial preferred stock of
FirstFederal and after satisfaction of FirstFederal's liabilities, in the event
of liquidation, dissolution or winding up of FirstFederal, holders of shares of
FirstFederal Common Stock are entitled to receive, pro rata, any remaining
assets available for distribution. In the event of liquidation, dissolution or
winding up of FirstFederal, holders of Series B Preferred Stock will be entitled
to receive, subject to the rights of creditors but before any distribution or
payment to the holders of FirstFederal Common Stock or any shares subordinate to
Series B Preferred Stock, a liquidation preference of $25 per share, plus
accrued and unpaid dividends to the date of distribution.

ASSESSMENT AND REDEMPTION

         Shares of FirstFederal Common Stock are and will be, when issued, fully
paid and nonassessable. Such shares do not have any redemption provisions.

ANTITAKEOVER PROVISIONS

         Certain of the provisions of the FirstFederal Articles summarized in
the succeeding paragraphs may be deemed to have an antitakeover effect and may
delay a tender offer or takeover attempt which a shareholder might consider in
such shareholder's best interest, including attempts which might result in the
payment to shareholders of a premium over the market price for FirstFederal's
shares.

         The shares of FirstFederal Common Stock do not have cumulative voting
rights. As a result, the holders of more than 50% of the voting power of all
securities outstanding voting for the elections of directors can elect 100% of
the directors if they choose to do so. In such event, the holders of the
remaining voting power will not be able to elect any person or persons, to the
FirstFederal Board.

         The FirstFederal Board is comprised of 12 directors divided into three
classes, with four directors in each class. Each director serves a three-year
term. Terms of office expire on a staggered basis and, as a result, it would
generally take two annual meetings to effect a change in membership of a
majority of the FirstFederal Board.

         The FirstFederal Articles provide that all actions required or
permitted to be taken by the shareholders may be voted upon at any annual or
special meeting of the shareholders or by written consent of all the
shareholders entitled to vote thereon in lieu of a meeting, and specifies that
special meetings of the shareholders may be called by the Chairman of the Board,
the President, the Board of Directors by action at a meeting or a majority of
the directors acting without a meeting, and that special meetings will be called
upon written request of the holders of 50% of all the shares outstanding and
entitled to vote at the meeting.

         The rights of FirstFederal's shareholders are governed by the
FirstFederal Articles, the FirstFederal Code and Ohio law, including Chapter
1701 of the Ohio Revised Code (including the Ohio Control Share Acquisition
Statute), as each of the foregoing may from time to time be amended. Pursuant to
the Ohio Control Share Acquisition Statute, the purchase of shares with certain
levels of voting power of FirstFederal (one-fifth or more, one-third or more or
a majority) can be made only with the prior authorization of (i) the holders of
at least a majority of the total voting power and (ii) the holders of at least
a majority of the total voting power held by shareholders other than the        
proposed acquirer, officers of FirstFederal elected or appointed by the
FirstFederal Board and directors of FirstFederal who are also employees and
excluding certain shares that are transferred after the announcement of the
proposed acquisition and prior to the vote with respect to the proposed
acquisition. The Ohio Control Share Acquisition Statute applies to all Ohio
corporations with significant Ohio contacts, fifty or more shareholders and
which do not have a provision in their articles of incorporation or code of
regulations to the effect that it does not apply. Since neither the
FirstFederal Articles nor the FirstFederal Code contain such a provision, the
Ohio Control Share Acquisition Statute applies to FirstFederal.

         Chapter 1704 of the Ohio Revised Code, among other things, prohibits
certain mergers, sales of assets, issuances or purchases of securities,
liquidation or dissolution, or reclassification of the then outstanding shares
of an Ohio corporation involving, or for the benefit of, certain holders of
stock representing 10% or more of the voting power (other than current 10%
shareholders who do not increase their present proportional interest), unless
(a) such transactions are approved by the directors of such corporation prior to
the 10% shareholder becoming such, or (b) the acquisition of 10% of the voting
power is approved by the directors of such corporation prior to the 10%
shareholder becoming such, or (c) the transaction involves a 10% shareholder
which has been such for at least three years and is approved by holders of
two-thirds of the voting power of the company and the holders of a majority of
the voting power not owned by the 10% shareholder or certain minimum price and
form of consideration requirements are met; and Section 1707.043 of the Ohio
Revised Code provides Ohio corporations, or in certain circumstances the
shareholders of an Ohio corporation, a cause of action to recover profits
realized under certain circumstances by persons who dispose of securities of a
corporation within 18 months of proposing to acquire such corporation. The

Control Share Acquisition Statute and Chapter 1704 and Section 1707.043 of the
Ohio Revised Code may have the effect of deterring certain potential
acquisitions of FirstFederal which might be beneficial to FirstFederal's
shareholders.

         Except for proposals to amend, repeal, alter or rescind (i) Article
Eighth, which among other things sets forth the circumstances under which
special meetings of the shareholders may be called, (ii) Article Ninth, which
among other things sets forth the range of the number of directors, procedures
upon the existence of vacancies, and classification requirements, (iii) Article
Tenth, which sets forth the procedure for removal of directors, (iv) Article
Eleventh, which among other things sets forth certain restrictions on the
acquisition by certain persons of shares of the FirstFederal and further sets
forth procedures in the event such restriction are violated, (v) Article
Twelfth, which contains a fair price provision and which, subject to certain
exceptions, requires the approval of a Business Combination (as defined therein)
by two-thirds or more of the shares entitled to vote in an election of
directors, and (vi) Article Fifteenth, which requires the affirmative vote of
not less than two-thirds of the voting power of FirstFederal to amend, repeal,
alter or rescind it or any of the above-stated articles, any amendment, repeal,
alteration or rescission of the remaining articles of the FirstFederal Articles
may be authorized from time to time by the affirmative vote of not less than a
majority of the voting power of FirstFederal.

         The FirstFederal Code may be repealed, altered, amended or rescinded by
the shareholders of FirstFederal by the vote of the holders of not less than a
majority of the voting power of FirstFederal entitled to vote at a meeting of
shareholders called for that purpose.

FAIR PRICE PROVISION

         The FirstFederal Articles contain a provision (the "Fair Price
Provision") which, in certain circumstances, requires a Business Combination
between FirstFederal and a Related Person (as defined therein) or certain
persons affiliated with the Related Person to meet specified criteria as to
price and procedural requirements which may have the effect of making a Business
Combination prohibitively expensive for an acquiring company, and thus may have
an antitakeover effect. The discussion herein of the Fair Price provision is
qualified in its entirety by reference to the FirstFederal Articles.

         The FirstFederal Articles require that any "Business Combination"
involving a "Related Person" (which generally includes any person or entity
owning or controlling more than 10% of the outstanding voting stock), must be
approved by the holders of at least two-thirds of the outstanding shares
entitled to vote, unless the Business Combination has been approved in advance
by two-thirds of the "Continuing Directors" (as defined therein). In the event
the requisite approval of the FirstFederal Board is obtained, the vote required
under applicable Ohio law would apply or, for certain transactions, no
shareholder vote would be necessary.

         The two-thirds shareholder vote generally required to approve a
Business Combination may have the effect of foreclosing mergers and other
business combinations which a majority of FirstFederal shareholders deem
desirable and place the power to prevent such a merger or combination in the
hands of a minority of shareholders.

         COMPARISON OF RIGHTS OF SHAREHOLDERS OF FIRSTFEDERAL FINANCIAL
                 SERVICES CORP AND FIRST SHENANGO BANCORP, INC.

INTRODUCTION

         Upon consummation of the Merger, holders of the common stock of First
Shenango, a Pennsylvania corporation, whose rights are currently governed by
Pennsylvania law and First Shenango's Articles of Incorporation (the "First
Shenango Articles") and Amended Bylaws (the "First Shenango Bylaws"), will
become shareholders of FirstFederal, an Ohio corporation, and their rights will
be governed by Ohio law and the FirstFederal Articles and Code. Certain
differences arise from the change in governing law, as well as from differences
between the First Shenango Articles and Bylaws and the FirstFederal Articles and
Code. The following discussion is not intended to be a complete statement of all
differences affecting the rights of shareholders and is qualified in its
entirety by reference to the First Shenango Articles and Bylaws and FirstFederal
Articles and Code and Pennsylvania and Ohio law. See "Available Information."

ISSUANCE OF CAPITAL STOCK

         The First Shenango Articles authorize the issuance of 15,000,000 shares
of First Shenango Common Stock and 10,000,000 shares of Serial Preferred Stock,
no par value. At May 4, 1998, 2,069,007 shares of First Shenango Common Stock
were issued and outstanding, and no shares of preferred stock were issued and
outstanding. The FirstFederal Articles authorize the issuance of 20,000,000
shares of common stock, par value $1.00 per share, and 1,500,000 shares of
serial preferred stock, no par value. At May 4, 1998, 6,756,868 shares of
FirstFederal Common Stock were issued and outstanding and 428,348 shares of
FirstFederal's Series B Preferred Stock were issued and outstanding. First
Shenango and FirstFederal are authorized to issue additional shares of capital
stock up to the amount authorized under their respective Articles without
shareholder approval. As noted elsewhere herein, at the FirstFederal Annual
Meeting, FirstFederal's shareholders will be asked to adopt an amendment to the
FirstFederal Articles to increase the number of authorized shares of
FirstFederal Common Stock from 20,000,000 to 40,000,000.
"See Amendment to FirstFederal Articles to Increase Authorized Shares."

SHAREHOLDER ACTION BY UNANIMOUS CONSENT

         The First Shenango Articles and Bylaws provide that no action required
to be taken at any annual or special meeting of shareholders may be taken
without a meeting and specifically denies the power of shareholders to consent
in writing to the taking of any action without a meeting.

         Under Ohio Law, shareholders may take any action required or permitted
to be taken without a meeting if the unanimous written consent of all
shareholders entitled to vote on the matter is obtained. The FirstFederal
Articles provide that any action required or permitted to be taken at a meeting
of shareholders may be taken without a meeting if consents in writing, setting
forth the action so taken, are signed by all of the shareholders entitled to
vote thereon.

ADVANCE NOTICE REQUIREMENTS FOR NOMINATIONS OF DIRECTORS AND SHAREHOLDER
PROPOSALS

         The First Shenango Articles provides that nominations for the election
of directors may be made by any shareholder entitled to vote generally in the
election of directors by following certain procedures set forth therein. In
order for a First Shenango shareholder to make a nomination, he or she must give
notice in writing to First Shenango not fewer than 60 days prior to the
anniversary date of the immediately preceding annual meeting of shareholders of
First Shenango. The shareholder's notice must contain certain information
specified by the First Shenango Articles.

         The FirstFederal Code provides that FirstFederal shareholders may make
nominations for the election of directors by delivering written notice of such
nominations to the Secretary of FirstFederal not less than 30 days prior to the
date of the annual meeting of shareholders. In the event that less than 40 days
notice of the date of the meeting is given to shareholders, notice of nomination
by the shareholder must be received no later than ten business days following
the date on which notice of the meeting was mailed. The shareholder's notice
must contain certain

                                       53


<PAGE>   65



information specified by the FirstFederal Code. Furthermore, if the FirstFederal
Board fails to nominate candidates for the board at least 20 days prior to the
annual meeting, then nominations may be made at the meeting by any shareholder
entitled to vote.

         The First Shenango Articles provide that for any shareholder proposal
to be considered at an annual meeting of shareholders, notice thereof must be
delivered to, or mailed to and received at, the principal executive offices of
First Shenango at least 60 days prior to the anniversary date of the immediately
preceding annual meeting of shareholders. The shareholder's notice must contain
certain information specified by the First Shenango Articles.

         The FirstFederal Code provides that for any shareholder proposal to be
considered at an annual meeting of shareholders, notice thereof must be
delivered to or received at the principal executive offices of FirstFederal not
less than 30 days prior to the meeting, provided that in the event less than 40
days' notice of the meeting is given to shareholders, notice of the shareholder
proposal must be received not later than the close of business on the tenth day
following the day on which notice of the meeting was mailed. The shareholder's
notice must contain certain information specified by the FirstFederal Code.

SPECIAL MEETINGS OF SHAREHOLDERS

         Pennsylvania law permits the calling of special meetings of
shareholders by (i) the board of directors of a corporation, (ii) unless
otherwise provided in the corporation's articles of incorporation, by
shareholders entitled to cast at least 20% of the votes that all shareholders
are entitled to cast at the particular meeting or (iii) by such officers or
other persons as may be provided for in the corporation's bylaws. The First
Shenango Articles provide that special meetings of shareholders may be called
only by (i) the affirmative vote of a majority of the First Shenango Board, (ii)
the Chairman of the First Shenango Board or (iii) the President of First
Shenango.

         Under Ohio law, meetings of stockholders may be called by: (i) the
holders of at least 25% of the outstanding shares entitled to vote at the
meeting unless the corporation's articles of incorporation or code of
regulations specify another percentage, which may not be greater than 50%, (ii)
the directors of the corporation by action at a meeting or by a majority of the
directors acting without a meeting, (iii) the Chairman of the Board, the
President, or in case of the President's absence, the Vice President authorized
to exercise the authority of the President and (iv) such other officers or
persons as the articles of incorporation or code of regulations authorize to
call such meetings. The FirstFederal Articles permit a special meeting of
shareholders to be called by (i) the Chairman of the FirstFederal Board, (ii)
the President of FirstFederal, (iii) the FirstFederal Board by action at a
meeting or by a majority of the FirstFederal Board acting without a meeting or
(iv) upon the written request of the holders of at least 50% of all shares
outstanding and entitled to vote at the meeting.

NUMBER AND TERM OF DIRECTORS

         The First Shenango Board currently consists of seven directors. The
First Shenango Articles provide that the number of directors may be changed by
the affirmative vote of two-thirds of the then-current members of the First
Shenango Board. Under the First Shenango Articles, the number of directors may
not be fewer than five or more than 15. The First Shenango Board is divided into
three classes with three members in one class and two members in two classes.

         The FirstFederal Board is currently comprised of twelve directorships,
divided into three classes of four members each. The term of each director is
three years. The FirstFederal Articles provide that the number of directors may
be changed by the approval of two-thirds of the then-current members of the     
First Federal Board. Under the FirstFederal Articles, the number of directors
may not be fewer than six nor more than 15 (exclusive of two directors which
may be elected by the holders of all series of preferred stock in the event
FirstFederal is in default in payment of full dividends on any series of
preferred stock for six dividend payment periods).

                                       54


<PAGE>   66



FILLING VACANCIES ON THE BOARD OF DIRECTORS

         The First Shenango Articles provide that any vacancy (including one
resulting from a newly created directorship) that occurs on the First Shenango
Board may be filled by a majority vote of the First Shenango Board and that any
director appointed to fill the vacancy shall hold office for a term expiring at
the annual meeting of shareholders at which the term of the class to which he or
she has been elected expires. The FirstFederal Articles provide that any vacancy
(including one resulting from a newly created directorship) that occurs on the
FirstFederal Board may be filled by the affirmative vote of two-thirds of the
directors then in office and that any director appointed to fill the vacancy
shall hold office for a term expiring at the annual meeting of shareholders at
which the term of the class to which he or she has been elected expires.

REMOVAL OF DIRECTORS

         Both the First Shenango Articles and the FirstFederal Articles provide
that one or more directors may be removed only with cause upon the affirmative
vote of the holders of at least a majority of the outstanding shares entitled to
vote generally in the election of directors.

CUMULATIVE VOTING NOT PERMITTED

         The First Shenango Articles and FirstFederal Articles each provide that
shareholders may not cumulate their votes in the election of directors.

AMENDMENT OF ARTICLES OF INCORPORATION, BYLAWS AND CODE OF REGULATIONS

         The First Shenango Articles provide as a general matter that amendments
to the First Shenango Articles must first be approved by the majority of the
First Shenango Board and then approved by the holders of a majority of the
shares entitled to vote generally in the election of directors. Approval by the
holders of 80% of the shares entitled to vote generally in the election of
directors is required for amendments to provisions relating to (i) the number,
election, classification and removal of directors; (ii) preemptive rights; (iii)
elimination of directors' liability; (iv) indemnification of directors,
officers, employees and agents; (v) meetings of shareholders and shareholder
proposals; (vi) restrictions on voting First Shenango Common Stock; (vii)
approval of certain business combinations; and (viii) amendment of the First
Shenango Articles and Bylaws.

         The First Shenango Articles provide that the First Shenango Bylaws may
be amended by either (i) the affirmative vote of a majority of the directors
then in office or (ii) the shareholders of First Shenango, by the affirmative
vote of the holders of a majority of the shares of First Shenango entitled to
vote generally in the election of directors, except that approval by the holders
of at least 80% of the shares is required for amendments to the First Shenango
Bylaws relating to (i) the number and powers of directors; (ii) the manner for
filling vacancies on the First Shenango Board and removing members of the First
Shenango Board; (iii) limitations on the personal liability of directors; (iv)
approval of certain business combinations; and (v) constructions of terms
appearing in the First Shenango Bylaws.

         The FirstFederal Articles provide that amendments to the FirstFederal
Articles may be made upon the affirmative vote of a majority of the voting power
of FirstFederal, except that amendments relating to (i) shareholder meetings;
(ii) the number, election, classification and removal of directors; (iii)
acquisitions of control without regulatory approval; (iv) certain business
combinations; and (v) amendment of the FirstFederal Articles, require the
affirmative vote of two-thirds of the voting power of FirstFederal entitled to
vote at the meeting called for that purpose. However, the two-thirds vote
requirement does not apply to an amendment to the article relating to certain
business combinations if two-thirds of the entire FirstFederal Board recommends
the amendment to the shareholders. The FirstFederal Code may be amended by a
majority of the voting power of FirstFederal entitled to vote at a meeting
called for that purpose.

LIMITATIONS ON VOTING OR ACQUISITIONS OF CAPITAL STOCK

         Pennsylvania has a "control share acquisition" statute which limits the
voting rights of persons acquiring certain percentages of the outstanding shares
of a corporation's voting stock unless shareholder approval of the acquisition
is obtained. The First Shenango Articles specifically provide that
Pennsylvania's control share acquisition statute does not apply to First
Shenango. The First Shenango Articles do provide, however, that, with limited
exceptions, no owner of greater than ten percent of the outstanding shares of
First Shenango Common Stock (the "Limit") may vote any of the shares in excess
of the Limit.

         Ohio has a control share acquisition statute to which FirstFederal is
subject. See "Description of FirstFederal Common Stock--Antitakeover
Provisions." The FirstFederal Articles also provide that if any person, without
obtaining the requisite regulatory approval, acquires ten percent or more of the
voting power of the outstanding shares entitled to vote generally in the
election of directors, such person loses the right to vote, receive dividends on
and take actions otherwise authorized for shareholders to take with respect to
the shares in excess of ten percent of the outstanding shares.

APPROVAL OF MERGERS, CONSOLIDATIONS, ETC.

         The First Shenango Articles require approval by at least 80% of the
voting shares of First Shenango for certain "Business Combinations." A "Business
Combination" is defined in the First Shenango Articles to include sales,
exchanges, leases, transfers or other dispositions of assets, mergers or
consolidations, liquidations or dissolutions of First Shenango, involving First
Shenango on the one hand and an "Interested Shareholder" or any affiliate or
associate thereof on the other hand. An "Interested Shareholder" is defined as
any person who (i) is the beneficial owner of 20% or more of the outstanding
shares of First Shenango entitled to vote generally in the election of directors
(a "20% beneficial owner") or (ii) is an affiliate or associate of First
Shenango and at any time within the previous five years was a 20% beneficial
owner.

         The supermajority vote requirement does not apply to any Business
Combination where two-thirds of the members of the First Shenango Board who were
members of the First Shenango Board prior to the time that the Interested
Shareholder became an Interested Shareholder (the "Unrelated Directors") have
approved the Business Combination or where the Business Combination is (i)
approved by the affirmative vote of a majority of the voting shares of First
Shenango entitled to vote generally in the election of directors (excluding
shares held by the Interested Shareholder and any affiliate or associate
thereof) at a meeting held no earlier than three months after the Interested
Shareholder became such, provided the Interested Shareholder is at the time of
the meeting the beneficial owner of at least 80% of the shares entitled to vote
generally in the election of directors and provided certain fair price
requirements are met; (ii) approved by the affirmative vote of the holders of
all of the outstanding shares of First Shenango Common Stock; (iii) approved by
the affirmative vote of a majority of the voting shares of First Shenango
entitled to vote generally in the election of directors (excluding shares held
by the Interested Shareholder or any affiliate or associate thereof) at a
meeting called for such purpose at least five years after the date on which the
Interested Shareholder first became an Interested Shareholder; or (iv) approved
at a shareholders' meeting called for such purpose no earlier than five years
after the date on which the Interested Shareholder first became an Interested
Shareholder provided certain fair price requirements are satisfied.

         The supermajority vote requirement under the First Shenango Articles
for certain Business Combinations does not apply to the Merger Agreement, which,
as noted elsewhere in this Joint Proxy Statement/Prospectus, requires the
approval of a majority of the outstanding shares of First Shenango Common Stock.

         The FirstFederal Articles contain a provision similar to the First
Shenango Articles for certain Business Combinations with "Related Persons."
However, under the FirstFederal Articles, the general vote requirement for
certain Business Combinations is two-thirds of the outstanding shares entitled
to vote in the election of directors generally (as opposed to 80% of the
outstanding voting shares, under the First Shenango Articles). In addition,
under the FirstFederal Articles as under the First Shenango Articles, an
exemption from the supermajority vote requirement may generally be obtained by
approval of two-thirds of the Unrelated Directors. See "Description of
FirstFederal Common Stock--Fair Price Provision."

                                       56


<PAGE>   68



PAYMENT OF DIVIDENDS

         The ability of First Shenango and FirstFederal to pay dividends on
their common stock is governed by Pennsylvania and Ohio law, respectively.

         Pennsylvania law provides that, unless otherwise restricted by its
bylaws, a corporation may make distributions to its shareholders unless (i) the
corporation would be unable to pay its debts as they become due in the usual
course of its business or (ii) the total assets of the corporation would be less
than the sum of its liabilities plus the amount that would be needed, if the
corporation were to be dissolved, to satisfy the preferential rights upon
dissolution of any shares senior to the class receiving the distribution.

         Ohio law provides that dividends may be paid out of surplus in cash,
property or shares of the corporation's capital stock. The dividend may not
exceed the combination of the surplus of the corporation and the difference
between (i) the reduction in surplus that results from the immediate recognition
of the transition obligation under Statement of Financial Accounting Standards
No. 106 ("SFAS No. 106") issued by the Financial Accounting Standards Board; and
(ii) the aggregate amount of the transition obligation that would have been
recognized as of the date of the declaration of a dividend or distribution if
the corporation had elected to amortize its recognition of the transition
obligation under SFAS No. 106.

         The ability of First Shenango and FirstFederal to pay dividends is also
affected by regulatory restrictions on the abilities of their subsidiaries to
make capital distributions.

PREEMPTIVE RIGHTS

         Neither the FirstFederal shareholders nor the First Shenango
shareholders have preemptive rights.

                           AMENDMENT TO FIRSTFEDERAL'S
             ARTICLES OF INCORPORATION TO INCREASE AUTHORIZED SHARES

         The FirstFederal Board has approved and recommends to FirstFederal's
shareholders for their adoption at the FirstFederal Annual Meeting an amendment
to the FirstFederal Articles to increase the number of shares of FirstFederal
Common Stock authorized for issuance thereunder from 20,000,000 to 40,000,000.
While adoption of the amendment is not a condition to consummation of the
Merger, if the amendment is not adopted by the FirstFederal shareholders,
FirstFederal will soon be severely hindered in its ability to issue additional
shares of FirstFederal Common Stock and unduly restricted in the conduct of its
financial affairs. As of May 4, 1998, there were 6,756,868 shares of
FirstFederal Common Stock issued and outstanding. As of that date, there were
an additional 1,487,347 shares of FirstFederal Common Stock reserved for
issuance upon conversion of up to 428,348 shares of FirstFederal's Series B
Preferred Stock and upon exercise of stock options outstanding. Approximately
1,689,217 shares of FirstFederal Common Stock are expected to be issued upon
the occurrence of the five-for-four stock split in the form of a stock dividend
that has been declared by FirstFederal, payable on May 22, 1998 to shareholders 
of record as of May 4, 1998. In connection with the Merger, approximately
2,353,025 shares of FirstFederal Common Stock will be issued to First Shenango
shareholders, and an additional 124,671 shares of FirstFederal Common Stock
will be issuable to holders of options to purchase First Shenango Common Stock.

         The proposed amendment would give FirstFederal greater flexibility in
its financial affairs before and after the Merger by making 20 million
additional shares of FirstFederal Common Stock available for issuance in such
transactions and at such times as the FirstFederal Board considers appropriate,
whether in public or private offerings, as stock splits or dividends or in
connection with mergers and acquisitions or otherwise. FirstFederal's
shareholders may or may not be given the opportunity to vote on such a
transaction, depending on the nature of the transaction, applicable law, the
rules and policies of the National Association of Securities Dealers, Inc.
applicable to Nasdaq National Market issuing companies and the judgment of the
FirstFederal Board regarding the submission of such transaction to a vote of
FirstFederal shareholders. FirstFederal has no present plans, understandings or
agreements for the issuance or use of the proposed additional shares of
FirstFederal Common Stock. Because shareholders do not have preemptive rights
under the FirstFederal Articles, the interests of existing shareholders may
(depending on the particular circumstances in which additional capital stock is
issued) be diluted by any such issuance.

                                       57


<PAGE>   69



         It is possible that additional shares of FirstFederal Common Stock
could be issued for the purpose of making an acquisition by an unwanted suitor
of a controlling interest in FirstFederal more difficult, time-consuming or
costly or to otherwise discourage an attempt to acquire control of FirstFederal
Common Stock. Under such circumstances, the availability of authorized and
unissued shares may make it more difficult for shareholders of FirstFederal to
obtain a premium for their shares. Such authorized and unissued shares could be
used to create voting or other impediments or to frustrate a person or other
entity seeking to obtain control of FirstFederal by means of a merger, tender
offer, proxy contest or other means. For instance, such shares could be
privately placed with purchasers who might cooperate with the FirstFederal Board
in opposing an attempt by a third party to gain control of FirstFederal by
voting such shares against the transaction with the third party or could be used
to dilute the stock ownership or voting rights of a person or entity seeking to
obtain control of FirstFederal. Although the FirstFederal Board does not
currently anticipate issuing additional shares of FirstFederal Common Stock for
purposes of preventing a takeover of FirstFederal, the FirstFederal Board
reserves its right (consistent with its fiduciary responsibilities) to issue
shares for such purpose.

         If the amendment is adopted, the first sentence of the Fourth Article
of the First Federal Articles would be amended to read as follows:

         "FOURTH: The aggregate number of shares of all classes of capital stock
which the corporation has authority to issue is forty-one million five hundred
thousand shares of which forty million shares are to be shares of common stock,
par value $1.00 per share, and of which one million five hundred thousand are to
be shares of serial preferred stock, without par value per share."

         Adoption of the proposed amendment requires the affirmative vote of a
majority of the issued and outstanding shares of FirstFederal Common Stock. As
soon as practicable after such affirmative vote has been taken and certified,
the amendment will be filed with the Secretary of State of the State of Ohio and
will thereupon become effective.

         THE FIRSTFEDERAL BOARD RECOMMENDS THAT FIRSTFEDERAL SHAREHOLDERS VOTE
"FOR" ADOPTION OF THE AMENDMENT TO THE FIRSTFEDERAL ARTICLES TO INCREASE THE
NUMBER OF AUTHORIZED SHARES OF FIRSTFEDERAL COMMON STOCK.

                           AMENDMENT TO FIRSTFEDERAL'S
                    ARTICLES OF INCORPORATION TO CHANGE NAME

         The corporate name of FirstFederal since its incorporation has been
"FirstFederal Financial Services Corp." This name was selected at the time of
FirstFederal's incorporation in 1989 because FirstFederal's primary purpose was
to serve as the parent holding company of First Federal Savings and Loan
Association of Wooster. As noted elsewhere herein, in July 1997, First Federal
Savings and Loan Association of Wooster converted from a federal savings
association to a national bank, and concurrently therewith changed its name to
"Signal Bank, N.A." In order to reflect the new name of FirstFederal's lead
subsidiary, Signal Bank, the FirstFederal Board recommends to FirstFederal's
shareholders for their adoption at the FirstFederal Annual Meeting an amendment
to the FirstFederal Articles to change FirstFederal's name to "Signal Corp".

         If the amendment is adopted, the First Article of the FirstFederal
Articles would be amended to read as follows:

         "FIRST:           The name of the Corporation is "Signal Corp".

         Approval of the amendment requires the affirmative vote of a majority
of the issued and outstanding shares of FirstFederal Common Stock. As soon as
practicable after such affirmative vote has been taken and certified, the
amendment will be filed with the Secretary of State of the State of Ohio.

         THE FIRSTFEDERAL BOARD RECOMMENDS THAT FIRSTFEDERAL SHAREHOLDERS VOTE
"FOR" ADOPTION OF THE AMENDMENT TO FIRSTFEDERAL'S ARTICLES OF INCORPORATION TO
CHANGE FIRSTFEDERAL'S NAME.

                       ELECTION OF FIRSTFEDERAL DIRECTORS

GENERAL

         Directors of FirstFederal are generally elected to serve for three-year
terms or until their respective successors are elected and qualified. One-third
of the directors are generally elected annually. At the FirstFederal Annual
Meeting, FirstFederal's shareholders will be asked to elect seven directors,
including three directors appointed during fiscal 1997 whose current terms will
expire at the FirstFederal Annual Meeting (David J. Olderman, David C. Vernon
and Joseph P. Ciolek) and a nominee not yet serving as a director (James J.
Little). It is intended that the proxies solicited on behalf of the FirstFederal
Board (other than proxies in which the vote is withheld as to one or more
nominees) will be voted at the FirstFederal Annual Meeting for the election of
the nominees identified below. There are no arrangements or understandings
between any director or nominee and any other person pursuant to which such
director or nominee was selected. If any nominee is unable to serve, the shares
represented by all valid proxies will be voted for the election of such
substitute as the FirstFederal Board may recommend.

         The following table sets forth certain information regarding the
FirstFederal Board, including members' terms of office and their beneficial
ownership of FirstFederal Common Stock as of May 4, 1998. The following
directors beneficially owned more than 1% of the shares of FirstFederal Common
Stock outstanding as of May 4, 1998, as follows: Mr. Stein 6.35%, Mr. James     
5.73%, and Mr. Clark 1.16%. No other director beneficially owned more than 1%
of the shares of FirstFederal Common Stock outstanding as of May 4, 1998.

         EMPLOYMENT AGREEMENTS. Signal Bank has entered into employment
agreements with Messrs. Clark, Douce and Little. The employment agreements
provide for an annual base salary in an amount not less than each individual's
respective current salary and provide for a salary review by the Signal Bank
Board not less often than annually. The agreements also provide for termination
upon the employee's death, for cause or in certain other events specified in the
agreements. The employment agreements are also terminable by the employee upon
90 days written notice to Signal Bank.

         The employment agreements provide for payment (in lieu of salary) to
Messrs. Clark, Douce and Little of an amount equal to 299% of their five year
average base compensation, respectively, in the event there is a "change in
control" of Signal Bank where employment terminates in connection with such
change in control or within 12 months thereafter. If the employment of Messrs.
Clark, Douce and Little had been terminated as of December 31, 1997 under
circumstances entitling them to severance pay as described above, they would
have been entitled to receive lump sum cash payments of approximately $682,000,
$440,000 and $612,000, respectively.

REPORT ON EXECUTIVE COMPENSATION OF THE COMPENSATION AND BENEFITS AND STOCK
OPTION COMMITTEES

         All executive officers of FirstFederal also currently hold positions
with Signal Bank and receive their primary cash compensation from Signal Bank.
Decisions on cash compensation of FirstFederal's executives are made by the
three member Compensation and Benefits Committees of the FirstFederal and Signal
Bank Boards. All decisions by the Compensation and Benefits Committees relating
to the cash compensation of FirstFederal's executive officers are reviewed by
the full FirstFederal and Signal Bank Boards, except that FirstFederal and
Signal Bank Board members who are also executive officers of FirstFederal or
Presidents of subsidiaries do not participate in deliberations regarding their
respective compensation.

         Set forth below is a report prepared by Messrs. Stein, Geralis and
Plumly in their capacities as members of the Compensation and Benefits
Committees and by Messrs. Stein and Geralis in their capacities as members of
the FirstFederal Board's Stock Option Committee. This report addresses the
compensation policies for 1997 as they affected the Chief Executive Officer and
other executive officers of FirstFederal.

                  Compensation Policies Toward Executive Officers Generally. The
         Compensation and Benefits Committees' executive compensation policies
         are designed to provide competitive levels of compensation that
         integrate pay with FirstFederal's annual and long-term performance
         goals, reward above-average company performance, recognize individual
         initiative and achievements, and assist FirstFederal in attracting and
         retaining qualified executives. Target levels of the executive
         officers' overall compensation are intended to be competitive with the
         compensation being paid to executive officers of a peer group of
         publicly traded financial institutions in Ohio and the Midwest.

                  The Stock Option Committee endorses the position that stock
         ownership by management and stock-based performance compensation
         arrangements are beneficial in aligning management's and shareholders'
         interests in the enhancement of shareholder value. Thus, the
         Compensation and Benefits Committees have also utilized these elements
         in the compensation packages for FirstFederal's executive officers.

                  Relationship of Performance Under Compensation Plans.
         Compensation paid to Messrs. Clark, Douce and Little in 1997, as
         reflected in the foregoing tables, primarily consisted of the following
         elements: base salary, awards accrued pursuant to the Management
         Incentive Compensation Plan (the "Incentive Plan"), additional bonus
         awards and matching contributions pursuant to the Signal Bank 401(k)
         Plan. In addition (as indicated in the tables above), during 1997, the
         Stock Option Committee awarded stock options under the 1997 Omnibus
         Incentive Plan to Messrs. Clark, Douce and Little.

                                       66
<PAGE>   78



                  Management Incentive Compensation. The Incentive Plan is a
         cash bonus plan under which awards may be authorized on an annual basis
         by the FirstFederal Board's Compensation and Benefits Committee to
         participants if certain performance goals are met by FirstFederal.

                  Awards under the Incentive Plan have been based upon (i)
         FirstFederal's success in attaining a targeted return on average equity
         (net earnings divided by average equity) in excess of a minimum
         threshold goal established annually in advance by the FirstFederal
         Board, and (ii) with respect to executives other than Messrs. Clark,
         Douce and Little, individual performance.

                  Twenty percent of the incentive awards for Messrs. Clark,
         Douce and Little in 1997 were based upon FirstFederal's attainment of a
         targeted return on average equity. Because of various transactions
         effected by FirstFederal during fiscal 1997 which prevented
         FirstFederal from attaining the return on equity targeted by the
         Management Incentive Plan, the amount of bonuses available to be
         awarded to Messrs. Clark, Douce and Little under such plan for fiscal
         1997 were determined by the FirstFederal Board's Compensation and
         Benefits Committee to be inadequate in view of FirstFederal's overall
         performance during fiscal 1997. The FirstFederal Board's Compensation
         and Benefits Committee therefore determined to award additional bonuses
         for 1997 to Messrs. Clark, Douce and Little outside of the Management
         Incentive Plan.

                  Stock Incentive Plan. The long-term incentive component of the
         executive officers' 1997 compensation arose under the 1997 Omnibus
         Incentive Plan.

                  The 1997 Omnibus Incentive Plan provides for awards in the
         form of stock options, stock appreciation rights, limited stock
         appreciation rights, restricted stock and performance awards. Each
         award is made on such terms and conditions, consistent with the 1997
         Omnibus Incentive Plan, as the Stock Option Committee may determine. No
         awards of stock appreciation rights or limited stock appreciation
         rights have been made. The stock options granted to date generally have
         been exercisable in three years, and in no event later than ten years,
         from the date of the grant. Under the 1997 Omnibus Incentive Plan, the
         Committee may grant either "Incentive Stock Options," as defined under
         Section 422 of the Code, or stock options not intended to qualify as
         such. FirstFederal does not receive any cash consideration for the
         granting of options under the 1997 Omnibus Incentive Plan. Shares may
         be either authorized but unissued shares or reacquired shares held by
         FirstFederal in its treasury. Any shares subject to an award which
         expires or is terminated unexercised will again be available for
         issuance under the 1997 Omnibus Incentive Plan.

                  Messrs. Clark and Douce have received annual awards of stock
         options since 1987. During 1997, the Stock Option Committee granted to
         Messrs. Clark, Douce and Little options to purchase the number of
         shares of FirstFederal Common Stock as indicated in the "Option Grants
         in Last Fiscal Year" table above.

                  Other Compensation Plans. At various times in the past, Signal
         Bank has adopted certain broad-based employee benefit plans in which
         the executive officers are permitted to participate on the same terms
         as non-executive employees who meet applicable eligibility criteria,
         subject to any legal limitations on the amounts that may be contributed
         or the benefits that may be payable under the plans.

                  Pursuant to the Signal Bank 401(k) Plan, participants are
         permitted to make annual salary reduction contributions to the Signal
         Bank 401(k) Plan in amounts of 1% to 15% of their salary. Prior to
         January 1, 1997, the participant's salary reduction contribution was
         matched by contributions in FirstFederal Common Stock based on a
         formula up to a maximum of 2% of the participant's salary for those
         participants who qualified. Effective January 1, 1997, this maximum
         percentage was raised to 3%. Supplemental matching contributions may be
         contributed from time to time, in FirstFederal Common Stock, upon
         approval of the Signal Bank Board. In connection with the termination
         of Signal Bank's Pension Plan, the Signal Bank 401(k) Plan was amended
         to permit Signal Bank to apply what would have been the average annual
         cost of continuing to fund the Pension Plan toward annual
         "age-weighted" contributions to the Signal Bank 401(k) Plan (in
         addition to Signal Bank's regular matching contributions). An
         employee's share of any age-weighted contributions to the Signal Bank
         401(k) Plan will increase as the employee becomes older, unless the
         employee's salary simultaneously decreases significantly.


                                       67
<PAGE>   79


                  For 1997, Signal Bank's matching and age-weighted
         contributions to the Signal Bank 401(k) Plan for Messrs. Clark, Douce
         and Little were $21,530, $16,695 and $11,941, respectively.

                  Effective July 1, 1997, FirstFederal commenced operation of
         its 1997 Employee Stock Purchase Plan (the "Purchase Plan") which was
         approved at FirstFederal's Annual Meeting of Shareholders held on April
         22, 1997. The Purchase Plan allows for employee purchases of
         FirstFederal Common Stock at a discount from the market price through
         periodic payroll deductions in a manner intended to qualify for
         favorable tax treatment under Section 423 of the Code. During fiscal
         1997, Mr. Little participated in the Purchase Plan; Messrs. Clark and
         Douce elected not to participate in the Purchase Plan during fiscal
         1997.

                  Determination of Chief Executive Officer's Compensation. The
         Compensation and Benefits Committees based the Chief Executive
         Officer's 1997 compensation on the policies described above for
         executive officers generally. A significant portion of the Chief
         Executive Officer's potential compensation is tied to FirstFederal's
         performance. In targeting compensation for the Chief Executive Officer,
         the Compensation and Benefits Committees also seek to be competitive
         with the total compensation being paid to the Chief Executive Officers
         of comparable publicly traded financial services companies. The
         Compensation and Benefits Committees have targeted the Chief Executive
         Officer's total compensation at or slightly above the median total
         compensation paid to Chief Executive Officers of these comparable
         companies. The members of the Compensation and Benefits Committees are
         Directors Steven N. Stein, (Chairman), Gust G. Geralis and Daniel H.
         Plumly. The members of the Stock Option Committee are Directors Steven
         N. Stein (Chairman) and Gust B. Geralis.

PERFORMANCE GRAPH

         FirstFederal's proxy statement relating to its Annual Meeting of
Shareholders held on April 22, 1997 included a graph comparing the cumulative
total stockholder return on FirstFederal's Common Stock to a savings and loan
industry index. Because of Signal Bank's conversion in July 1997 from a federal
savings association to a national bank and FirstFederal's July 1997 acquisition
of Summit Bank (and FirstFederal's registration as a bank holding company and
deregistration as a savings and loan holding company), the FirstFederal Board
believes it is now more appropriate to compare the return on the FirstFederal
Common Stock to an industry index comprised of banks (or their holding
companies) as well as savings and loans (or their holding companies). The
following graph compares the cumulative total stockholder return on the
FirstFederal Common Stock to a broad index of the Nasdaq Stock Market, a
combined bank and thrift industry index and the savings and loan industry index
utilized in last year's Annual Meeting proxy statement for the period from
December 31, 1992 through December 31, 1997. The graph assumes that $100 was
invested on December 31, 1992 and that all dividends were reinvested.

CERTAIN TRANSACTIONS

         Pursuant to FirstFederal's policies, all transactions with senior
policy-making officers and directors must be on terms and conditions comparable
to those for similar transactions with non-affiliates. In addition, all loans
and other transactions between FirstFederal and such officers and directors will
be subject to approval by a majority of the FirstFederal Board, including a
majority of its disinterested directors. Signal Bank and Summit Bank continue to
follow a policy of granting to employees loans for the financing and improvement
of their personal residences as well as consumer loans on substantially the same
terms and collateral, except for interest rates and waiver of certain fees, as
those of comparable transactions prevailing at the time.

         On December 31, 1997, Director Ronald A. James, Jr., owner of Hudson
Mobile Insurance Agency and Indy Mobile Insurance Agency, entered into an
agreement with Signal Bank for the sale of such agencies for approximately $1.1
million in cash.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         Director Daniel H. Plumly, a member of the FirstFederal and Signal Bank
Boards' Compensation and Benefits Committees is a principal in the law firm of
Critchfield, Critchfield & Johnston, Ltd., Wooster, Ohio ("Critchfield").
Critchfield has provided legal services to Signal Bank for many years and to
FirstFederal since its incorporation in 1989. During 1997, compensation paid to
Critchfield for legal services totaled $900,448, as follows: FirstFederal -
$92,345; Signal Bank - $183,457; Signal Securitization Corp. (a subsidiary of
FirstFederal) - $265,150; Summit Bank - $16,115; MCi - $179,717; Alliance, a
subsidiary of Signal Bank; - $64,429; Signal Finance Co., a subsidiary of Signal
Bank, $10,288; all other subsidiaries of Signal Bank - $565; borrowers of Signal
Bank and the sellers of real estate in connection with the closing of real
estate loans made by Signal Bank - $88,382.

         Mr. Plumly is also a partner in Heartland Title Agency. During 1997,
Heartland Title Agency received $25,726 from borrowers of Signal Bank and the
sellers of real estate for escrow services, premiums for title insurance, title
search fees and other matters relating to closing real estate loans.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Exchange Act requires FirstFederal's directors and
executive officers, and persons who own more than 10% of a registered class of
FirstFederal's equity securities, to file with the SEC initial reports of
ownership and reports of changes in ownership of FirstFederal Common Stock and
other equity securities of FirstFederal. Officers, directors and greater than
10% stockholders are required by SEC regulations to furnish FirstFederal with
copies of all Section 16(a) forms they file.

         To FirstFederal's knowledge, based solely on a review of the copies of
such reports furnished to FirstFederal and written representations that no other
reports were required during the fiscal year ended December 31, 1997, all
Section 16(a) filing requirements applicable to its officers, directors and
greater than 10% beneficial owners were complied with, except for the
inadvertent failure to timely file a Form 3 by Director Olderman. A Form 3 was
subsequently filed by Mr. Olderman.

                      ELECTION OF FIRST SHENANGO DIRECTORS

         The First Shenango Board is presently composed of seven members who are
elected for terms of three years, with approximately one-third of the directors
elected annually in accordance with the First Shenango Bylaws. At the First
Shenango Annual Meeting, two directors will stand for election.

         It is intended that the persons named in the proxies solicited by the
First Shenango Board will vote for the election of the named nominees. If any
nominee is unable to serve, the shares represented by all valid proxies will be
voted for the election of such substitute as the First Shenango Board may
recommend. At this time, the First Shenango Board knows of no reason why any
nominee might be unavailable to serve.

         The following table sets forth each nominee and continuing director's
name, age, the year he first became a director of First Shenango or New Castle
Bank, the year in which his term will expire and the number of shares and
percentage of First Shenango Common Stock beneficially owned.

- ----------

(1)      At December 31, 1997.

(2)      At May 4, 1998.

(3)      Pursuant to rules promulgated under the Exchange Act, a person or
         entity is considered to beneficially own shares of First Shenango
         Common Stock if he or she directly or indirectly has or shares (1)
         voting power, which includes the power to vote or to direct the voting
         of the shares; or 

(2)      investment power, which includes the power to dispose or direct the
         disposition of the shares. Unless otherwise indicated, includes all
         shares held directly by the named individuals as well as by spouses,
         minor children in trust and other indirect ownership, over which shares
         the named individual effectively exercises sole voting and investment
         power.

(4)      Includes 11,873 restricted shares awarded to Mr. Bonadio and 2,710
         restricted shares granted to each non-employee director pursuant to the
         Management and Directors Stock Bonus Plans. These shares were granted
         in connection with the New Castle Bank's conversion from mutual to
         stock form on April 5, 1993 and became fully vested on April 5, 1997.
         Mr. Hrach did not become a Director until 1996 and thus did not receive
         such an award.

(5)      Includes shares of First Shenango Common Stock subject to options
         granted pursuant to the 1993 Stock Option Plan which are currently
         exercisable or will become exercisable within 60 days of the First
         Shenango Record Date.

(6)      Excludes 106,508 shares of Common Stock (5.15%) held by the New Castle
         Bank's Employee Stock Ownership Plan (the "ESOP") for which such
         non-employee directors (Directors Eckles, Hrach and Rentz) serve as
         plan trustees and exercise shared voting and investment power. Shares
         which are unallocated to participating employees (presently 55,129
         shares) and shares for which no voting directions are received are
         voted by the plan trustees. Once allocated to participant accounts,
         such First Shenango Common Stock will be voted by the plan trustees as
         directed by each plan participant as the beneficial owner of such First
         Shenango Common Stock. The plan trustees act as fiduciaries within the
         meaning of the Employee Retirement Income Security Act of 1974, as
         amended ("ERISA"). The individuals serving as plan trustees disclaim
         beneficial ownership of stock held under the ESOP.

(7)      Includes 5,000 shares held in trust by a self-directed IRA account,
         2,000 shares held directly by spouse, and 2,570 shares held jointly by
         spouse, son and daughter.

(8)      Includes 10,761 shares held jointly with spouse, and 108 shares held
         directly by spouse.

(9)      Includes 8,650 shares held in trust by a self-directed IRA account.

(10)     Includes 10,000 shares held jointly with spouse, 3,200 shares held
         directly by spouse, 2,035 shares held directly by sons, and 7,240
         shares allocated under the ESOP.

(11)     Messrs. Bergey and Carlson have been nominated to serve three year
         terms to expire in 2001. Notwithstanding the foregoing, if the Merger
         occurs, First Shenango will cease to exist and the terms of Messrs.
         Bergey and Carlson will automatically expire upon consummation of the
         Merger.

(12)     Includes 100 shares held jointly with spouse.

director of the First Shenango Board is set forth below.

First Shenango Board, meetings of the Board of Directors of New Castle Bank (the
"New Castle Bank Board") and meetings of the committees of the New Castle Bank
Board. During the fiscal year ended December 31, 1997, the First Shenango Board
held ten regular meetings and one special meeting. The New Castle Bank Board
held twenty-three regular meetings and two special meetings. No director
attended fewer than 75% of the total meetings of the First Shenango or New

         The Compensation Committee of the New Castle Bank Board consists of
Robert H. Carlson - Chairman, William G. Eckles, II and Richard E. Rentz, Jr.
The committee meets annually to review the performance of New Castle Bank's
officers and employees, and to determine compensation programs and adjustments.
The Compensation

Committee met once during fiscal 1997.

         The Audit Committee of the New Castle Bank Board consists of Ronald P.
Bergey - Chairman, Robert H. Carlson and Dale R. Perelman. The Audit Committee
reviews the actions and reports of the internal audit department and the
independent auditor. The Committee also provides direction to the internal
auditor. The Committee meets as needed. There were four regular meetings in
1997.

         The First Shenango Board does not have a standing nominating committee.
The First Shenango Board acted as the nominating committee to nominate directors
to serve on the First Shenango Board. The nominating committee met once during
the twelve months ended December 31, 1997. Although the First Shenango Board
acting as the nominating committee will consider nominees recommended by
shareholders, it has not actively solicited recommendations from shareholders of
the First Shenango. Director nominations by shareholders must be received at the
executive office of First Shenango not less than 60 days prior to the
anniversary date of the preceding annual shareholder meeting pursuant to written
notice made in accordance with the First Shenango Bylaws.

Chairman of the Board received an additional fee of $100 per month. No
additional fees are paid for New Castle Bank Board committee meetings. For the
fiscal year ended December 31, 1997, total fees paid to directors for New Castle
Bank Board meetings and committee meetings were $87,600. No separate fees are
paid for attendance at First Shenango Board or First Shenango Board committee

converted into options to purchase shares of FirstFederal Common Stock upon
consummation of the Merger. See "The Merger -- Treatment of First Shenango Stock
Options."

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The New Castle Bank Board's Compensation Committee met once during the
fiscal year ended December 31, 1997 to review compensation paid to executive
officers and to determine the level of any increases in the salary budget for
executive officers to take effect during the following year. The committee
reviews various published surveys of


                                       74
<PAGE>   86



compensation paid to executives performing similar duties for depository
institutions and their holding companies, with a particular focus on the level
of compensation paid by comparable institutions in and around the New Castle
Bank's market area, including institutions with total assets of between $200
million and $500 million. Although the committee does not set compensation
levels for executive officers based on whether particular financial goals have
been achieved by First Shenango, the committee does consider the overall
profitability of First Shenango when making these decisions. With respect to
each particular executive officer, his or her contributions to First Shenango
over the past year are also evaluated. For the fiscal year ended December 31,
1997, Francis A. Bonadio, President and Chief Executive Officer, received an
increase in salary from $140,000 to $144,000, as disclosed in the Summary
Compensation Table.

         STOCK OPTION PLAN. In connection with New Castle Bank's conversion from
mutual to stock form in April 1993 and acquisition of the outstanding stock of
New Castle Bank by First Shenango, the First Shenango Board adopted the First
Shenango Bancorp, Inc. 1993 Stock Option Plan (the "Option Plan"), which was
ratified by First Shenango's shareholders at First Shenango's Special Meeting of
Shareholders held in August 1993. Pursuant to the Option Plan, 224,825 shares of
First Shenango Common Stock are reserved for issuance upon exercise of stock
options granted or to be granted to officers, directors and key employees of
First Shenango and its subsidiaries from time to time. The purpose of the Option
Plan is to provide additional incentive to certain officers, directors and key
employees by facilitating their purchase of a stock interest in First Shenango.
The Option Plan provides for a term of ten years, after which no awards may be
made, unless earlier terminated by the First Shenango Board pursuant to the
Option Plan.

         The following table sets forth additional information concerning
options granted under the Option Plan.

which are not exercised prior to the Effective Time will be converted into
options to purchase FirstFederal Common Stock. See "The Merger -- Treatment of

         MANAGEMENT AND DIRECTORS STOCK BONUS PLANS. The New Castle Bank Board
has adopted two stock bonus plans (the "Management Stock Bonus Plan" and the
"Directors Stock Bonus Plan", collectively, the "Stock Bonus Plans" or the
"MSBPs") as a method of providing directors, officers, and key employees of New
Castle Bank with a proprietary interest in First Shenango in a manner designed
to encourage such persons to remain in the employment or service of New Castle
Bank. New Castle Bank has contributed sufficient funds to the MSBP Trusts which
enabled the MSBP Trusts to purchase First Shenango Common Stock representing
3.85% of the aggregate number of shares


                                       75
<PAGE>   87



issued in connection with New Castle Bank's conversion from mutual to stock form
(i.e., 89,930 shares First Shenango Common Stock). Awards under the MSBPs were
made in recognition of prior and expected future services to New Castle Bank of
its directors and executive officers responsible for implementation of the
policies adopted by the First Shenango Board, the profitable operation of New
Castle Bank, and as a means of providing a further retention incentive and
direct link between compensation and the profitability of New Castle Bank.

         The Merger Agreement provides that no additional shares may be granted
under the Stock Bonus Plans and that the remaining shares available through the
Stock Bonus Plans will be cancelled or returned to First Shenango as authorized
but unissued shares.

OTHER BENEFITS

         INSURANCE. Full-time employees of New Castle Bank are provided with
group plan insurance that covers hospitalization, major medical, dental,
long-term disability and life insurance. This insurance is available generally
and on the same basis to all full-time employees following completion of
approximately three months of employment. New Castle Bank pays the premium for
employee coverage. The employee pays the premiums for dependent coverage, if
any.

         PENSION PLAN. New Castle Bank sponsors a tax-qualified defined benefit
pension plan (the "Pension Plan"). All full-time employees of New Castle Bank
are eligible to participate after one year of service and attainment of age 21.
A qualifying employee becomes fully vested in the Pension Plan upon completion
of five years of service. The Pension Plan is intended to comply with ERISA.
Total New Castle Bank pension expense for the fiscal years ended December 31,
1997, 1996 and 1995 amounted to $0, $0, and $48,637, respectively.

         The Pension Plan provides for monthly payments to each participating
employee at normal retirement age (age 65). The annual benefits payable under
the Pension Plan are equal to 1.25% of Final Average Compensation ("FAC") as
defined in the pension plan, excluding overtime, commission and bonus pay
multiplied by years of service. A participant may elect an early retirement at
age 55 with 10 years of service, and may elect to receive a reduced monthly
benefit. The Pension Plan also provides for payments in the event of disability
or death. At December 31, 1997, Mr. Bonadio had 21 years of credited service
under the Pension Plan.

         Benefits are payable in the form of various annuity alternatives,
including a joint and survivor option, or in a lump-sum amount. The following
table shows the estimated annual benefits payable under the Pension Plan based
on the respective employee's years of credited service and applicable average
annual salary as calculated under the Pension Plan. For the Pension Plan year
ended June 30, 1997, the highest permissible annual benefit under the Internal
Revenue Code ("Code") is $125,000, as indexed. Benefits under the Pension Plan
are not subject to offset for Social Security benefits.

         401(k) PROFIT SHARING PLAN. New Castle Bank sponsors a tax-qualified
defined contribution profit sharing plan, (the "401(k) Plan"), for the benefit
of its employees. Employees become eligible to participate under the 401(k)
Plan after age 18 and completing one year of service. Under the 401(k) Plan,
employees may voluntarily elect to defer up to 9% of compensation, not to
exceed applicable limits under the Code (i.e., $9,500 in 1997). The first 4% of
employee savings is matched by an employer contribution of $.50 for each $1.00
of employee contribution. Such matching contributions shall be 100% vested      
following completion of three years of service. Additionally, New Castle Bank
may contribute an annual discretionary contribution to the plan. Such benefits
are allocated to participant accounts as a percentage of base compensation of
such participant to the base compensation of all participants. Total
contributions to the 401(k) Plan by New Castle Bank for all employees for the
fiscal years ended December 31, 1997, 1996, and 1995 were $28,793, $24,089, and
$21,436, respectively.

         EMPLOYEE STOCK OWNERSHIP PLAN. New Castle Bank has established an
employee stock ownership plan (the "ESOP"), for the exclusive benefit of
participating employees. Participating employees are employees who have
completed one year of service with New Castle Bank or its subsidiaries and
attained age 21. The ESOP is to be funded by contributions made by New Castle
Bank in cash or First Shenango Common Stock. Benefits may be paid either in
shares of First Shenango Common Stock or in cash. The ESOP borrowed funds from
New Castle Bank with which to acquire 112,412 shares, or 4.81% of the shares
issued in the mutual-to-stock conversion of New Castle Bank. At February 28,
1998, the ESOP held 106,508 shares, or 5.15% of the shares issued and
outstanding at that date. Shares purchased with such loan proceeds are held in
a suspense account for allocation among participants as the loan is repaid. New
Castle Bank anticipates contributing approximately $112,412 annually to the
ESOP to meet principal obligations under the ESOP loan, plus applicable
interest payments. This loan is expected to be fully repaid in approximately
ten years. New Castle Bank contributed $173,881 to the ESOP for the fiscal year
ended December 31, 1997.

         The First Shenango Board has appointed a committee (the "ESOP
Committee") and a board of trustees (the "ESOP Trustees") to administer the
ESOP. The ESOP Committee consists of Directors Eckles, Hrach and Rentz, as does
the board of trustees. The First Shenango Board or the ESOP Committee may
instruct the ESOP Trustees regarding investment of funds contributed to the
ESOP. The ESOP Trustees must vote all shares allocated to participant accounts
held under the ESOP in accordance with the instructions of the participating
employees. Unallocated shares and allocated shares for which no timely direction
is received will be voted by the ESOP Trustees as directed by the First Shenango
Board or the ESOP Committee, subject to the ESOP Trustees' fiduciary duties.

         Pursuant to the terms of the ESOP, upon the Effective Time the ESOP
will terminate without further action or notice, all participants' accounts will
be considered fully vested and nonforfeitable, all contributions, stock
dividends, and earnings on the ESOP's assets paid to the ESOP's trust or earned
by such trust as of the most recent valuation date (as defined in the ESOP) will
be allocated to the accounts of all participants as of the date of termination
and all assets realized (after the repayment of the existing loan between First
Shenango and the ESOP) by the ESOP's trust with respect to the First Shenango
Common Stock currently held as collateral, which will be exchanged in the
Merger, will be allocated as earnings of such trust. First Shenango is not
expected to make any contributions to the ESOP in connection with the Merger
other than normal amortization of the loan.

         SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN. New Castle Bank has implemented
a supplemental executive retirement plan ("SERP") for the benefit of Mr.
Bonadio. The purpose of the SERP is to furnish Mr. Bonadio with supplemental
post-retirement benefits in addition to those which will be provided under New
Castle Bank's Pension Plan and other retirement benefits. It is anticipated that
benefits payable under the SERP will equal approximately $1,000 per month upon
retirement at age 65 for a minimum of 120 months. Payments under the SERP are
being accrued for financial reporting purposes during the period of Mr.
Bonadio's employment. The SERP is unfunded. All benefits payable under the SERP
will be paid from current assets of New Castle Bank. There are no tax
consequences to either Mr. Bonadio or New Castle Bank related to the SERP prior
to payment of benefits. Upon receipt of payment of benefits, Mr. Bonadio will
recognize taxable ordinary income in the amount of such payments received and
the New Castle Bank will be entitled to recognize a tax-deductible compensation
expense at that time. First Shenango's expenses for 1997, 1996 and 1995 were
$10,030, $28,997, and $32,389 offset by deferred taxes of approximately $3,000,
$10,000, and $11,000, respectively.


                                       77
<PAGE>   89


         The Merger will not result in any change in the amount or timing of the
monthly benefit provided under the SERP. While the SERP does not provide for the
payment of a lump sum rather than monthly benefits, the Merger Agreement
provides that Mr. Bonadio may, after the Merger, elect to receive a lump sum
payment of the present value of the expected future payments under the SERP.

LONG TERM INCENTIVE PLANS

         First Shenango does not sponsor any long term incentive plans and made
no awards or payments under any such plans during the fiscal year ended December
31, 1997.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         The Compensation Committee of the First Shenango and New Castle Bank
Boards consists of Robert H. Carlson, Chairman, William G. Eckles, II and
Richard E. Rentz, Jr. The committee, which consists of non-employee directors of
First Shenango and New Castle Bank, meets annually to review the performance of
the New Castle Bank's officers and employees, and to determine compensation
programs and salary actions for the New Castle Bank and its personnel.

         Mr. Carlson's son has outstanding from New Castle Bank a mortgage loan
with a 7.375% interest rate. This loan had a balance of $133,551 on December 31,
1997 and the highest balance during 1997 was $137,014. Additional information
concerning this loan is provided under "Certain Transactions with Management and
Others."

PERFORMANCE GRAPH

         The following performance graph is for the period from April 6, 1993
(the first day of trading for First Shenango Common Stock) through December 31,
1997. The performance graph compares the cumulative total shareholder return on
First Shenango Common Stock with (a) the cumulative total shareholder return on
stocks included in the Nasdaq CRSP U.S. index and (b) the cumulative total
shareholder return on stocks included in the Nasdaq CRSP Bank index prepared for
Nasdaq by the Center for Research of Securities Prices (CRSP) at the University
of Chicago. Comparison of the First Shenango Common Stock with the Nasdaq Stock
Market and bank indices assumes the investment of $1,000 as of the close of     
trading on April 6, 1993. The cumulative total return for First Shenango is
computed assuming the reinvestment of dividends at the frequency with which
dividends were paid during the period.

         There can be no assurance that First Shenango's future stock
performance will be the same or similar to the historical stock performance
shown in the graph below. First Shenango will neither make nor endorse any
predictions as to stock performance.

CERTAIN TRANSACTIONS WITH MANAGEMENT AND OTHERS

         New Castle Bank, like many financial institutions, has followed a
policy of granting various types of loans to officers, directors and employees.
The loans have been made in the ordinary course of business and on substantially
the same terms, including interest rates and collateral, as those prevailing at
the time for comparable transactions with New Castle Bank's other customers, and
do not involve more than the normal risk of collectibility, nor present other
unfavorable features. All loans by New Castle Bank to its directors and
executive officers are subject to regulations of the Office of Thrift
Supervision ("OTS") restricting loans and other transactions with affiliated
persons of New Castle. Prior to the enactment of the Financial Institutions
Reform, Recovery and Enforcement Act ("FIRREA"), New Castle Bank provided loans
to officers and directors and other affiliates at reduced interest rates and
fees. The preferential rate on mortgage loans could be no less than the greater
of (i) New Castle Bank's cost of funds plus 100 basis points or (ii) the
Internal Revenue Service's applicable federal rate. In addition, New Castle Bank
routinely waived its points and application fees for affiliate loans. Effective
August 9, 1989, FIRREA required that all such loans be made on terms and
conditions comparable to those for similar transactions with non-affiliates. New
Castle Bank's affiliates must now qualify for any loans on the same terms and
conditions that apply to other customers. Furthermore, loans to an affiliate
must be approved in advance by a disinterested majority of the New Castle Bank
Board or be within other guidelines established as a result of OTS regulations.
Loans to executive officers and directors of the New Castle Bank, and their
affiliates aggregating $60,000 or more during the twelve months ended December
31, 1997, amounted to $435,639, or 1.58% of New Castle Bank's retained earnings
at December 31, 1997.

         The following table sets forth the indebtedness of executive officers,
directors, and members of the immediate family of an executive officer or
director who are or were indebted to New Castle Bank at any time during the
fiscal year ended December 31, 1997 in an amount in excess of $60,000 that was
originated prior to August 9, 1989.

audited by Deloitte & Touche LLP, independent auditors, as stated in their
report, which is incorporated herein by reference and have been so incorporated
in reliance upon the report of such firm given upon their authority as experts
in accounting and auditing.

         The consolidated financial statements of First Shenango as of December
31, 1997 and 1996 and for each of the years in the three year period ended
December 31, 1997 included in the First Shenango 1997 Form 10-K, and
incorporated by reference in this Joint Proxy Statement/Prospectus, have been
incorporated by reference herein in reliance upon the report of the accounting
firm of Ernst & Young LLP, incorporated by reference herein, and upon the
authority of said firm as experts in accounting and auditing.

                              SHAREHOLDER PROPOSALS

         First Shenango does not plan to hold a 1999 Annual Meeting of
Shareholders if the Merger is consummated as contemplated by the Merger
Agreement. In the event the Merger is not consummated as contemplated by the
Merger Agreement and First Shenango calls an Annual Meeting of Shareholders to
be held during 1999, any shareholder proposal to take action at such meeting
must be received at the main office of First Shenango, 25 North Mill Street, New
Castle, Pennsylvania 16101 no later than January 8, 1999. Any such proposal
shall be subject to the requirements of the proxy rules adopted under the
Exchange Act.

         In order to be eligible for inclusion in FirstFederal's proxy materials
for its 1999 Annual Meeting of Shareholders, any shareholder proposal to take
action at such meeting must be received at the main office of FirstFederal, 135
East Liberty Street, Wooster, Ohio 44691, no later than January 8, 1999. Any
such proposal shall be subject to the requirements of the proxy rules adopted
under the Exchange Act.

                              INDEPENDENT AUDITORS

         On August 20, 1996, the appointment of Deloitte & Touche LLP as
FirstFederal's independent auditors was terminated and KPMG Peat Marwick LLP was
engaged as FirstFederal's independent auditors. The decision to change
accountants was approved by the FirstFederal Board. In connection with the audit
of the fiscal year ended December 31, 1995 and the subsequent interim period
through August 20, 1996, there were no disagreements with Deloitte & Touche LLP
on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedures, which disagreements if not resolved
to their satisfaction would have caused Deloitte & Touche LLP to make reference
to the subject matters of the disagreements in connection with their audit
reports. The audit report of Deloitte & Touche LLP on the consolidated financial
statements of FirstFederal and subsidiaries as of and for the year ended
December 31, 1995, did not contain any adverse opinion or disclaimer of opinion,
nor were they qualified or modified as to uncertainty, audit scope, or
accounting principles.

         The FirstFederal Board has appointed KPMG Peat Marwick LLP as
independent auditors of FirstFederal for the fiscal year ending December 31,
1998. Representatives of KPMG Peat Marwick LLP are expected to attend the
FirstFederal Annual Meeting to respond to appropriate questions and to make a
statement if they so desire.

         The First Shenango Board has renewed First Shenango's arrangement with
Ernst & Young LLP to be First Shenango's independent auditors for the fiscal
year ending December 31, 1998. Representatives of Ernst & Young LLP are expected
to attend the First Shenango Annual Meeting to respond to appropriate questions
and to make a statement if they so desire.

         Time, each holder of a certificate or certificates theretofore
         representing outstanding shares of First Shenango Common Stock (any
         such certificate being hereinafter referred to as a "Certificate") may
         surrender the same to the Transfer Agent for cancellation and each such
         holder shall be entitled upon such surrender to receive in exchange

         pursuant to subsection (f) of Section 2.5, without interest, to which
         such holder is entitled. Until so surrendered, each Certificate shall

         shares of FirstFederal Common Stock into which the shares represented
         by such Certificates have been changed or converted as aforesaid. No
         dividends or other distributions declared after the Effective Time with

         thereof shall be entitled to receive any such dividends or other
         distributions, without any interest thereon, which theretofore had
         become payable with respect to shares of FirstFederal Common Stock
         represented by such Certificate. Holders of unsurrendered Certificates
         shall be entitled to vote after the Effective Time, at any meeting of
         FirstFederal shareholders, the number of whole shares of FirstFederal
         Common Stock represented by such Certificates, regardless of whether
         such holders have exchanged their Certificates; provided that no holder
         of unsurrendered Certificates may vote at any meeting of FirstFederal
         shareholders that is held more than 30 days after the Effective Time.
         Certificates surrendered for exchange by any person who is an
         "affiliate" of First Shenango or an affiliate of an affiliate for
         purposes of Rule 145(c) under the Securities Act of 1933, as amended,
         shall not be exchanged for certificates representing shares of
         FirstFederal Common Stock until FirstFederal has received the written
         agreement of such person contemplated by Section 5.3.1. If any
         certificate for shares of FirstFederal Common Stock is to be issued in
         a name other than that in which a Certificate surrendered for exchange
         is issued, the Certificate so surrendered shall be properly endorsed
         and otherwise in proper form for transfer.

                  Upon the Effective Time, the stock transfer books of First

         Agent nor any party to this Merger Agreement shall be liable to a
         holder of First Shenango Common Stock for any amount paid or property

         abandoned property, escheat or similar law.

                  (f) Notwithstanding any other provision hereof, each holder of
         shares of First Shenango Common Stock who would otherwise have been
         entitled to receive a fraction of a share of FirstFederal Common Stock
         (after taking into account all Certificates delivered by such holder)
         shall receive, in lieu thereof, cash in an amount equal to such
         fractional part of a share of FirstFederal Common Stock valued as
         follows: the average closing Sales Price as recorded on Nasdaq for the
         ten consecutive Trading Days ending on the third

         Trading Day prior to the Closing Date. No such holder shall be entitled
         to dividends, voting rights or any other shareholder right in respect
         of any fractional share.

                  (g) To the extent applicable under the PBCL, each outstanding
         share of First Shenango Common Stock the holder of which has perfected
         his right to dissent under the PBCL and has not effectively withdrawn
         or lost such right as of the Effective Time (the "First Shenango
         Dissenting Shares") will not be converted into or represent a right to
         receive shares of FirstFederal Common Stock (including cash for
         fractional shares), and the holder will be entitled only to such rights
         as are granted by the PBCL. First Shenango will give FirstFederal
         prompt notice upon receipt by First Shenango of any such written
         demands for payment of the fair value of such shares of First Shenango
         Common Stock and of withdrawals of such demands and any other
         instruments provided pursuant to PBCL (any shareholder duly making such
         demand being hereinafter called a "Dissenting Shareholder"). Any
         payments made in respect of First Shenango Dissenting Shares will be
         made by FirstFederal. If any Dissenting Shareholder effectively
         withdraws or loses (through failure to perfect or otherwise) his right
         to such payment prior to or at or after the Effective Time, such
         holder's shares of First Shenango Common Stock will be converted into a
         right to receive FirstFederal Common Stock in accordance with the
         applicable provisions of this Merger Agreement.

         2.6 STOCK OPTIONS. Except for those Stock Options exercised pursuant to
Section 5.1.15, Stock Options outstanding immediately prior to the Effective
Time entitling the holders thereof to purchase shares of First Shenango Common
Stock will remain unchanged and will remain outstanding when the Merger becomes
effective, except that upon the Effective Time, (i) the holders thereof shall
become entitled to purchase the number of shares of FirstFederal Common Stock
(rounded up to the nearest whole share) to which such holders would have been
entitled to receive pursuant to Section 2.5(a) if immediately preceding the
Effective Time, such securities were converted into such number of shares of
First Shenango Common Stock to which the holders would be entitled under the
terms of the governing documents for such securities, disregarding for purposes
of this Section any limitations on exercise or vesting thereof; and (ii) the
exercise price of each respective Stock Option shall be divided by the Exchange
Ratio. The Stock Options, and the FirstFederal Common Stock delivered upon
exercise of the Stock Option, shall be registered under the Securities Act of
1933.

                  accelerate the maturity of any obligation of First Shenango;
                  or

                           (iv) The creation or imposition of any Lien on any of
                  its Assets.

         3.3 CAPITAL STOCK. The authorized capital stock of First Shenango
Bancorp, Inc., consists of:

                  (a) 15,000,000 shares of common stock, $0.10 par value per
         share, of which 2,058,640 shares are issued and outstanding; and
         274,091 shares are held in treasury; and 10,367 shares are held in a
         benefit plan reserve.

                  (b) 10,000,000 shares of serial preferred stock without par

any preemptive right of any stockholder of First Shenango Bancorp, Inc. All of
the issued and outstanding shares of First Shenango Common Stock will be
entitled to vote to approve this Merger Agreement. As of the date hereof, no

stock of First Shenango to be exercised, distributed, or triggered, except as

         authority to carry on its business as now conducted; and (ii) is duly
         licensed or qualified to do business in the states of the United States
         where its ownership or leasing of property or the conduct of its

         be so licensed or qualified would have a Material Adverse Effect on
         First Shenango. Each Subsidiary has all federal, state, and local
         governmental authorizations necessary for it to own or lease its
         properties or assets and to carry on its business as is now being
         conducted, except where the failure to be so authorized would not have
         a Material Adverse Effect on First Shenango.

         3.11 TAXES.

                  (A) FILING OF TAX RETURNS. Except where properly extended,
         within the times and in the manner prescribed by law, First Shenango
         has filed all federal, state, and local tax returns required by law.
         Except as disclosed in Section 3.11 of the Disclosure Schedule, the
         federal income tax returns of First Shenango have not been audited or
         investigated by the Internal Revenue Service for the preceding five
         years. Except as reflected on Section 3.11 of the Disclosure Schedule,
         there are no present disputes as to taxes payable by First Shenango. In
         addition, all tax returns and reports required by applicable law or
         governmental regulations have been filed by First Shenango, and such
         returns and reports are (and as to such returns and reports not filed
         as of the date hereof,


                                       14

<PAGE>   113



         will be) true, correct, and complete in all material respects and
         present, fairly and accurately, the information required to be shown
         therein. There are no tax deficiencies assessed against First Shenango
         that would have a Material Adverse Effect on First Shenango, and there
         are no tax deficiencies proposed or threatened, and no audit of First
         Shenango by any federal, state or local authority is in progress, and
         First Shenango has not received notice regarding any audit.

                  (B) PAYMENT OF TAXES. Except as disclosed in Section 3.11(b)
         of the Disclosure Schedule, First Shenango has, within the time and in
         the manner prescribed by law, paid in full (and until the Closing Date
         will pay within the time and in the manner prescribed by law) payroll
         taxes (including, but not limited to, Social Security taxes), franchise
         taxes, sales and use taxes, personal property taxes, real estate taxes
         and assessments, and local, state and federal income taxes. In
         addition, First Shenango will pay or make timely provision for payment
         of all such taxes thereafter payable by First Shenango so that no lien
         for any such taxes will be placed (or attempted) upon any of the
         Assets, on or following the Closing Date.

                  (C) TAX RESERVES. Except as disclosed in Section 3.11(c) of
         the Disclosure Schedule, the amounts established as accruals for taxes
         on the Financial Statements and on the Books and Records of First
         Shenango are reasonably expected to be sufficient for the payment of
         all taxes of any kind, whether disputed or not, and whether accrued,
         due, absolute, contingent or otherwise, which were or which may be
         payable by First Shenango for any periods or fiscal years prior to or
         including the Closing Date, including all taxes imposed before or after
         the Closing Date which are attributable to any such period or fiscal
         year. No differences exist between the amounts of the book basis and
         the tax basis of Assets (net of Liabilities) that are not accounted for
         by an accrual on the Books and Records for federal income tax purposes.

                  (D) EXTENSIONS AND WAIVERS. Except as disclosed in Section
         3.11(d) of the Disclosure Schedule, First Shenango has not requested
         any extension of time within which to file any tax return, which tax
         return has not since been filed, nor has First Shenango executed any
         outstanding waivers or comparable consents regarding the application of
         the statute of limitations with respect to any taxes or tax returns.

Schedule:

                  (a) There is no pending or threatened litigation involving
         First Shenango as defendant or plaintiff. There is no suit, action,
         arbitration, or legal, administrative, or other proceeding, or
         governmental investigation pending or threatened, against or affecting
         First Shenango, or its business or Assets. To the best of its
         Knowledge, the matters set forth in Section 3.12 of the Disclosure
         Schedule, if decided adversely to First Shenango, will not result in a
         Material Adverse Impact on First Shenango. First Shenango is not in
         default with respect to any Order of any federal, state, local or
         foreign court, department, agency, or instrumentality.



                                       15

<PAGE>   114



                  (b) There are no facts or circumstances known to First
         Shenango that could reasonably be expected to give rise to any claim
         that would be required to be disclosed pursuant to clause (a) above.

         3.13 COMPLIANCE WITH LAWS. To the best of its Knowledge, First Shenango
has complied with and is not in violation of, applicable federal, state, or
local statutes, laws and regulations (including, without limitation, any

amended, except which individually or in the aggregate do not and insofar as
reasonably can be foreseen, in the future will not have a Material Adverse
Effect on First Shenango. Except as disclosed in Section 3.13 of the Disclosure
Schedule, no investigation or review by any governmental entity with respect to
First Shenango outside the ordinary course of business and not generally
applicable to entities engaged in the same business is pending or, to the
Knowledge of First Shenango, threatened, nor has any governmental entity
indicated an intention to conduct the same in each case other than those, the
outcome of which will not have a Material Adverse Effect on First Shenango.
Further, neither First Shenango nor to its Knowledge any employee, officer, or
director has knowingly engaged in any activity or knowingly omitted to take any
action which, in any material way, has resulted or reasonably could be expected
to result in the violation of (i) any local, state or federal law (including
without limitation the Bank Secrecy Act, the Community Reinvestment Act,
applicable consumer protection and disclosure laws and regulations, including
without limitation, Truth in Lending, Truth in Savings and similar disclosure
laws and regulations, and equal employment and employment discrimination laws

         3.14 BENEFIT PLANS.

                  (a) Section 3.14 of the Disclosure Schedule contains a true
         and complete list of all employee benefit plans within the meaning of
         Section 3(3) of the Employee Retirement Income Security Act of 1974, as
         amended ("ERISA") ("Employee Benefit Plans"), whether or not any such
         Employee Benefit Plans are otherwise exempt from the provisions of
         ERISA, established, maintained or contributed to or obligated to form a
         fund by First Shenango (First Shenango shall include, for purposes of
         this Section 3.14 only, all employers, whether or not incorporated,
         which by reason of common control are treated together with First
         Shenango as a single employer within the meaning of Code Section 414(b)
         and (c) since September 2, 1974.)



                                       16

<PAGE>   115



                  (b) First Shenango does not maintain or contribute to any such
         employee benefit plan subject to ERISA which is not in substantial
         compliance with ERISA, or which has incurred any accumulated funding
         deficiency within the meaning of Section 412 or 418B of ERISA, or which
         has applied for or obtained a waiver from the Internal Revenue Service
         of any minimum funding requirement under Section 412 of the Code. First
         Shenango has not incurred any liability to the Pension Benefit Guaranty
         Corporation ("PBGC") in connection with any employee benefit plan
         covering any employees of First Shenango or ceased operations at any
         facility or withdrawn from such plan in a manner which could subject it
         to liability under Section 4062(e), 4063 or 4064 of ERISA, and knows of
         no facts or circumstances which might give rise to any liability of
         First Shenango to the PBGC under Title IV of ERISA. First Shenango has
         not incurred any withdrawal liability within the meaning of Sections
         4201 and 4204 of ERISA, to any employee benefit plan which is a
         multiemployer plan (as defined in Section 4001 of ERISA), and no event
         has occurred, and there exists no condition or set of circumstances,
         which presents a material risk of the occurrence of any withdrawal from
         or the partition, termination, reorganization or insolvency of any
         multiemployer plan which could result in any liability to First
         Shenango.

                  (c) Full payment has been made of all amounts which First
         Shenango is required for any reason to have paid as contributions to
         any Employee Benefit Plan as of the last day of the most recent fiscal
         year of such Employee Benefit Plan ended prior to the final Closing
         Date. First Shenango has made adequate provision for reserves to meet
         contributions that have not been made because they are not yet due
         under the terms of any Employee Benefit Plan or related agreements.
         Benefits under all Employee Benefit Plans are as represented and have
         not been increased subsequent to the date as of which documents have
         been provided.

                  (d) Each Employee Benefit Plan intended to be qualified under
         Section 401(a) of the Code has been determined to be so qualified by
         the Internal Revenue Service and nothing has occurred since the
         effective date of the last such determination which resulted in or is
         likely to result in the revocation of such determination.

                  (e) No reportable event (as defined in Section 4043 of ERISA)
         has occurred with respect to any Employee Benefit Plan and First
         Shenango has not engaged in any transaction with respect to the
         Employee Benefit Plans which would subject First Shenango to a tax,
         penalty or liability for prohibited transactions under ERISA or the
         Code nor have any of First Shenango's directors, officers, or employees
         to the extent they or any of them are fiduciaries with respect to such
         plans, breached any of their responsibilities or obligations under
         Title I of ERISA.

                  (f) First Shenango has furnished FirstFederal with true and
         complete copies of: (i) all Employee Benefit Plans as in effect,
         together with all amendments thereto which will become effective at a
         later date; (ii) the most recent Internal Revenue Service determination
         letter issued with respect to each Employee Benefit Plan; and (iii)
         Form


                                       17

<PAGE>   116



         5500 for the most recent completed fiscal year for each Employee
         Benefit Plan required to file such form.

                  (g) There are no material actions, suits or claims pending or
         threatened, against the Assets of any Employee Benefit Plan.

                  (h) The plans are qualified under Code Section 401 and the
         associated trust funds are exempt from tax under Code Section 501.

                  (i) Each Employee Benefit Plan which First Shenango maintains
         has at all times been administered in material compliance with all
         applicable requirements of ERISA, including all reporting requirements,
         with respect to the Internal Revenue Service, the Department of Labor
         and the Pension Benefit Guaranty Corporation and including all
         disclosure requirements with respect to plan participants and
         beneficiaries.

                  (j) Except as disclosed in Disclosure Schedule Section 3.14,
         First Shenango does not maintain nor is it under any obligation or duty
         to establish any type of post retirement benefit, medical, or life
         insurance plan for its employees.

         Shenango, (ii) each parcel of Real Property leased by First Shenango
         (as lessor or lessee), and (iii) all Liens relating to or affecting any

         by First Shenango is free and clear of all Liens, pledges, equities,
         claims of others or restrictions whatsoever, except:

                           (i) Zoning and building ordinances and regulations
                  which do not prohibit or restrict the present use of the Real
                  Property;

                           (ii) Real estate taxes and assessments, both general
                  and special, which may be a Lien but are not yet due and

                  FirstFederal prior to the Closing Date.

         First Shenango has adequate rights of ingress and egress with respect
         to such Real Property, buildings, structures, facilities, fixtures and
         other improvements. First


                                       18

<PAGE>   117



         Shenango has not received any notice nor has Knowledge that the Real
         Property, as currently used by First Shenango, is in violation of any
         applicable federal, state or local statute, ordinance, order,
         requirement, law, rule or regulation (including without limitation,
         building, zoning or Environmental Laws) affecting the Real Property, or
         that would have a Material Adverse Effect on the value of the Real
         Property or its continued operation and use in the ordinary course of
         business.

                  (b) The zoning of the Real Property permits the presently
         existing improvements and the conduct and continuation of the business
         presently being conducted on such Real Property.

                  (c) First Shenango has a valid and subsisting leasehold estate
         in and the right to quiet enjoyment of the Real Property leased by it
         for the full term of the lease thereof. Each lease is a legal, valid
         and binding agreement, enforceable in accordance with its terms, of
         First Shenango and of each other person that is a party thereto, and
         except as set forth in Section 3.15(c) of the Disclosure Schedule,
         there is no, and First Shenango has not received notice of any default
         (or any condition or event which, after notice or lapse of time or
         both, would constitute a default) thereunder. None of the leases will
         terminate or lapse by reason of the transactions contemplated by this
         Merger Agreement.

         Schedule, the improvements on the Real Property are structurally sound
         and in good operating condition and in a state of good maintenance and
         repair, are adequate and suitable for the purposes for which they are
         presently being used and, to the Knowledge of First Shenango, there are
         no condemnation or appropriation proceedings pending or threatened
         against any of such Real Property or the improvements thereon.

         3.16 ASSETS. With respect to the Assets:

                  (a) Except as listed on Section 3.16(a) of the Disclosure

         any statute, law, ordinance, or regulation of any governmental entity
         affecting its Assets with respect to health, safety and environmental
         and pollution control, including the disposition of hazardous or toxic
         waste materials or emissions into the air, soil or water, or any form
         of contamination that would have a Material Adverse Effect on the value
         of the Assets or the continued use of the Assets by First Shenango in
         the ordinary course of business.

                  (b) Except as provided in Section 3.16(b) of the Disclosure

         free and clear of all Liens, encumbrances, security interests, pledges,
         equities, claims of others or restrictions whatsoever.

                  (c) All equipment owned by First Shenango and used in its

         with no material defects other than those items identified to
         FirstFederal in Section 3.16(c) of the Disclosure Schedule, and except
         as disclosed in Section 3.16(c) of the Disclosure Schedule, no

         normal maintenance of such equipment. Except as stated in Section
         3.16(c) of the Disclosure Schedule, no personal property used by First
         Shenango in connection with its business is held under any lease,
         security agreement, conditional sales contract, or other title
         retention or security arrangement, or is other than in the possession
         and under the control of First Shenango. The tangible personal property

attachment, which order, decree, judgment, stipulation, settlement, lien,
charge, encumbrance or attachment would have a Material Adverse Effect on First
Shenango.

                  (b) Each Contract required to be disclosed in Section 3.18(a)
         of the Disclosure Schedule is in full force and effect and constitutes
         a legal, valid and binding agreement, enforceable in accordance with
         its terms, of each party thereto; and except as disclosed in Section

         Knowledge of First Shenango, any other party to such Contract, is or
         has received notice that it is, in violation or breach of or default
         under any such Contract (or with notice or lapse of time or both, would
         be in violation or breach of or default under any such Contract). None
         of the Contracts disclosed in Section 3.18(a) of the Disclosure
         Schedule will terminate or lapse by reason of the transactions
         contemplated by this Merger Agreement.

                  (c) Except as disclosed in Section 3.18(c) of the Disclosure
         Schedule, First Shenango is not a party to or bound by any Contract
         that has been or could reasonably be expected to have, individually or
         in the aggregate with any other such Contracts, a Material Adverse
         Effect on First Shenango.

                  (d) Except as disclosed in Section 3.18(d) of the Disclosure
         Schedule attached hereto, there are no Contracts, commitments, leases,
         permits or other instruments necessary to hold the Assets by First
         Shenango, as and where now held by First Shenango, or to conduct the
         business of First Shenango, as and where now operated by First
         Shenango, or related to the operation or management of the Assets.

         3.19 POOLING OF INTERESTS. Other than as disclosed in Section 3.19 of
the Disclosure Schedule, as of the date of this Merger Agreement, First Shenango
knows of no reason relating to it which would reasonably cause it to believe

accounting purposes.

                           (iii) First Shenango has not received any notice that
                  it is in default (or with the giving of notice or lapse of

         Series B are outstanding as of December 31, 1997.

         All issued and outstanding shares of FirstFederal Common Stock are
validly issued and outstanding, fully paid and nonassessable and were not issued
in violation of any preemptive right of any stockholder of FirstFederal. As of
the date hereof, no shares of FirstFederal Common Stock were reserved for
issuance except that 1,149,984 shares were reserved for issuance upon the
exercise of options granted heretofore pursuant to FirstFederal's stock option
plan. Options have been granted with respect to 646,881 shares of FirstFederal
Common Stock, all of which are presently held by the employees, officers, and
directors of FirstFederal. As of the date hereof, there are no other outstanding
subscriptions, options, rights, warrants, convertible securities, or other
agreements or commitments obligating FirstFederal to issue (or to transfer from
treasury) any additional shares of its capital stock of any class.

         FirstFederal has taken all action necessary so that the execution of
this Merger Agreement and the consummation of the transactions contemplated
hereby do not and will not result in the grant of any rights to any person under
any agreements or enable rights to any capital stock of FirstFederal to be
exercised, distributed, or triggered, except as otherwise provided in this
Merger Agreement.

         4.4 SEC DOCUMENTS/REGULATORY FILINGS. FirstFederal Financial has filed
all SEC documents required by the security laws and such SEC documents complied
as of their respective dates of filing in all material respects with security
laws. FirstFederal has filed all reports required by statute or regulation to be
filed with any federal or state regulatory agency except where the failure to so
file would not have a Material Adverse Effect on FirstFederal, and such reports
were prepared in accordance with the applicable statutes, regulations, and
instructions in existence as of the date of filing of such reports in all
material respects.

         4.5 SUBSIDIARIES.

                  (a) FirstFederal does not own, directly or indirectly, 5% or
         more of the outstanding capital stock or other voting securities of any
         corporation, thrift, bank or other organization, except as disclosed on
         Section 4.5 of the Disclosure Schedule. The outstanding shares of
         capital stock of each Subsidiary are validly issued and outstanding,
         fully paid and nonassessable, and all such shares are directly owned by
         FirstFederal, free and clear of all liens, claims, and encumbrances. No
         Subsidiary has any outstanding securities of any kind, nor any
         outstanding options, warrants, or other rights entitling another person
         to acquire any securities of a Subsidiary of any kind other than the
         shares of capital stock owned by FirstFederal.

                  (b) Each Subsidiary is a duly organized corporation or
         national banking association validly existing and in good standing
         under applicable laws. Each Subsidiary (i) has all requisite power and
         authority to carry on its business as now conducted; and (ii) is duly
         licensed or qualified to do business in the states of the United States
         where its


                                       27

<PAGE>   126



         ownership or leasing of property or the conduct of its business
         requires such licensing or qualification and where failure to be so
         licensed or qualified would have a Material Adverse Effect on
         FirstFederal. Each Subsidiary has all federal, state, and local
         governmental authorizations necessary for it to own or lease its
         properties or assets and to carry on its business as is now being
         conducted, except where the failure to be so authorized would not have
         a Material Adverse Effect on FirstFederal.

         4.6 AFFILIATE TRANSACTIONS. Except as disclosed in Section 4.6 of the
Disclosure Schedule, as of the date of this Merger Agreement:

                           (i) There are no Liabilities between FirstFederal, on
                  the one hand, and the officers and directors of FirstFederal,
                  on the other hand, that were not incurred on an arm's length
                  basis;

                           (ii) No executive officer, director, or Affiliate of
                  a director or executive officer provides, provided, or caused
                  or causes to be provided any Assets, services, or facilities
                  to FirstFederal or otherwise does business with FirstFederal,
                  other than on an arm's length basis.

         4.7 BOOKS AND RECORDS. The Books and Records of FirstFederal fairly
reflect in all material respects the transactions to which it is a party and by
which its properties are subject or bound. Such Books and Records have been
properly kept and maintained in compliance in all material respects with GAAP
and all applicable legal requirements.

         4.8 FINANCIAL STATEMENTS. The FirstFederal Financial Statements, all
previously provided to First Shenango, fairly present the consolidated financial
position of FirstFederal Financial and its consolidated Subsidiaries as of the
date indicated, and the consolidated results of operations, changes in
shareholders' equity and cash flows of FirstFederal Financial and its
consolidated Subsidiaries for the period then ended in conformity with GAAP.
There are no material Liabilities of FirstFederal required to be disclosed in
FirstFederal's Financial Statements other than the Liabilities disclosed in such
Financial Statements (including footnotes). All monetary Liabilities and
material non-monetary Liabilities incurred after the date of the Financial
Statements were incurred in the ordinary course of business consistent with past
practices and in the aggregate are not material to FirstFederal's business.
Except for those Subsidiaries listed in Section 4.8 of the Disclosure Schedule,
the statements of financial condition and results of operations of each
Subsidiary are, and for all periods referred to in this Section 4.8 have been,
consolidated with those of FirstFederal Financial.

         4.9 ABSENCE OF CHANGES. Since December 31, 1997: (i) there has not been
any material adverse change, or any event or development which, individually or
together with other such events, could reasonably be expected to result in a
Material Adverse Impact of FirstFederal; (ii) neither FirstFederal's chief
executive officer nor its chief financial officer is aware of any events which
have occurred since December 31, 1997, or which are reasonably certain to occur
in the future and which reasonably can be expected to result in any Material
Adverse Impact of


                                       28

<PAGE>   127



FirstFederal; and (iii) there have been no material changes in the methods of
business operation of FirstFederal.

         4.10 CONSENT. Except as set forth in Section 4.10 of the Disclosure
Schedule, no consent, approval, order or authorization of, or registration,
declaration or filing with, any federal or state governmental authority is
required by or with respect to FirstFederal in connection with the execution and
delivery of this Merger Agreement or the consummation of the transactions
contemplated hereby.

         4.11 TAXES.

                  (A) FILING OF TAX RETURNS. Except where properly extended,
         within the times and in the manner prescribed by law, FirstFederal has
         filed all federal, state, and local tax returns required by law. Except
         as disclosed in Section 4.11(a) of the Disclosure Schedule, the federal
         income tax returns of FirstFederal have not been audited or
         investigated by the Internal Revenue Service for the preceding five
         years. Except as reflected on Section 4.11 of the Disclosure Schedule,
         there are no present disputes as to taxes payable by FirstFederal. In
         addition, all tax returns and reports required by applicable law or
         governmental regulations have been filed by FirstFederal, and such
         returns and reports are (and as to such returns and reports not filed
         as of the date hereof, will be) true, correct, and complete in all
         material respects and present, fairly and accurately, the information
         required to be shown therein. There are not and will not be any tax
         deficiencies assessed against FirstFederal that would have a Material
         Adverse Effect on FirstFederal, and there are no tax deficiencies
         proposed or threatened, and no audit of FirstFederal by any federal,
         state or local authority is in progress, and FirstFederal has not
         received notice regarding any audit.

                  (B) PAYMENT OF TAXES. FirstFederal has, within the time and in
         the manner prescribed by law, paid in full (and until the Closing Date
         will pay within the time and in the manner prescribed by law) payroll
         taxes (including, but not limited to, Social Security taxes), franchise
         taxes, sales and use taxes, personal property taxes, real estate taxes
         and assessments, and local, state and federal income taxes. In
         addition, FirstFederal will pay or make timely provision for payment of
         all such taxes thereafter payable by FirstFederal so that no Lien for
         any such taxes will be placed (or attempted) upon any of the Assets, on
         or following the Closing Date.

                  (C) TAX RESERVES. Except as disclosed in Section 4.11(c) of
         the Disclosure Schedule, the amounts established as accruals for taxes
         on the Financial Statements and on the Books and Records of
         FirstFederal are reasonably expected to be sufficient for the payment
         of all taxes of any kind, whether disputed or not, and whether accrued,
         due, absolute, contingent or otherwise, which were or which may be
         payable by FirstFederal for any periods or fiscal years prior to or
         including the Closing Date, including all taxes imposed before or after
         the Closing Date which are attributable to any such period or fiscal
         year. No differences exist between the amounts of the book basis and
         the tax basis of


                                       29

<PAGE>   128



         Assets (net of Liabilities) that are not accounted for by an accrual on
         the Books and Records for federal income tax purposes.

                  (D) EXTENSIONS AND WAIVERS. Except as disclosed in Section
         4.11(d) of the Disclosure Schedule, FirstFederal has not requested any
         extension of time within which to file any tax return, which tax return
         has not since been filed, nor has FirstFederal executed any outstanding
         waivers or comparable consents regarding the application of the statute
         of limitations with respect to any taxes or tax returns.

         4.12 LITIGATION. Except as disclosed in Section 4.12 of the Disclosure
Schedule:

                  (a) There is no material pending or threatened litigation
         involving FirstFederal as defendant or plaintiff. There is no suit,
         action, arbitration, or legal, administrative, or other proceeding, or
         governmental investigation pending or threatened, against or affecting
         FirstFederal, or its business or Assets that if decided adversely to
         FirstFederal, would result in a Material Adverse Effect on
         FirstFederal. FirstFederal is not in default with respect to any Order
         of any federal, state, local or foreign court, department, agency, or
         instrumentality.

                  (b) There are no facts or circumstances known to FirstFederal
         that could reasonably be expected to give rise to any claim that would
         be required to be disclosed pursuant to clause (a) above.

         4.13 COMPLIANCE WITH LAWS. To its Knowledge, FirstFederal has complied
with and is not in violation of, applicable federal, state, or local statutes,
laws and regulations (including, without limitation, any applicable building,
zoning, or other law, ordinance, or regulation) affecting its properties or the
operation of its business, including without limitation the Real Estate

Act of 1988, Civil Rights Act of 1991, Americans with Disabilities Act of 1991,
the Family and Medical Leave Act of 1993, as all such have been amended, except
which individually or in the aggregate do not and insofar as reasonably can be
foreseen, in the future will not have a Material Adverse Effect on FirstFederal.
Except as disclosed in Section 4.13 of the Disclosure Schedule, no investigation
or review by any governmental entity with respect to FirstFederal outside the
ordinary course of business and not generally applicable to entities engaged in
the same business is pending or, to the Knowledge of FirstFederal, threatened,
nor has any governmental entity indicated an intention to conduct the same in
each case other than those, the outcome of which will not have a Material
Adverse Effect on FirstFederal.

         Further, neither FirstFederal nor to its Knowledge any employee,
officer, or director has knowingly engaged in any activity or knowingly omitted
to take any action which, in any material way, has resulted or reasonably could
be expected to result in the violation of (i) any local, state


                                       30

<PAGE>   129



or federal law including without limitation the Bank Secrecy Act, the Community
Reinvestment Act, applicable consumer protection and disclosure laws and
regulations, including without limitation, Truth in Lending, Truth in Savings
and similar disclosure laws and regulations, and equal employment and employment
discrimination laws and regulations) or (ii) any regulation, order, injunction
or decree of any court or governmental body, the violation of either of which
could reasonably be expected to have a Material Adverse Effect on FirstFederal.

         4.14 BENEFIT PLANS.

                  (a) Section 4.14 of the Disclosure Schedule contains a true
         and complete list of all employee benefit plans within the meaning of
         Section 3(3) of ERISA ("Employee Benefit Plans"), whether or not any
         such Employee Benefit Plans are otherwise exempt from the provisions of
         ERISA, established, maintained or contributed to or obligated to form a
         fund by FirstFederal (FirstFederal shall include, for purposes of this
         Section 4.14 only, all employers, whether or not incorporated, which by
         reason of common control are treated together with FirstFederal as a
         single employer within the meaning of Code Section 414(b) and (c) since
         September 2, 1974.)

                  (b) FirstFederal does not maintain or contribute to any such
         employee benefit plan subject to ERISA which is not in substantial
         compliance with ERISA, or which has incurred any accumulated funding
         deficiency within the meaning of Section 412 or 418B of ERISA, or which
         has applied for or obtained a waiver from the Internal Revenue Service
         of any minimum funding requirement under Section 412 of the Code.
         FirstFederal has not incurred any liability to the Pension Benefit
         Guaranty Corporation ("PBGC") in connection with any employee benefit
         plan covering any employees of FirstFederal or ceased operations at any
         facility or withdrawn from such plan in a manner which could subject it
         to liability under Section 4062(e), 4063 or 4064 of ERISA, and knows of
         no facts or circumstances which might give rise to any liability of
         FirstFederal to the PBGC under Title IV of ERISA. FirstFederal has not
         incurred any withdrawal liability within the meaning of Sections 4201
         and 4204 of ERISA, to any employee benefit plan which is a
         multiemployer plan (as defined in Section 4001 of ERISA), and no event
         has occurred, and there exists no condition or set of circumstances,
         which presents a material risk of the occurrence of any withdrawal from
         or the partition, termination, reorganization or insolvency of any
         multiemployer plan which could result in any liability to FirstFederal.

                  (c) Full payment has been made of all amounts which
         FirstFederal is required for any reason to have paid as contributions
         to any Employee Benefit Plan as of the last day of the most recent
         fiscal year of such Employee Benefit Plan ended prior to the final
         Closing Date. FirstFederal has made adequate provision for reserves to
         meet contributions that have not been made because they are not yet due
         under the terms of any Employee Benefit Plan or related agreements.
         Benefits under all Employee Benefit Plans are as represented and have
         not been increased subsequent to the date as of which documents have
         been provided.

<PAGE>   130



                  (d) Each Employee Benefit Plan intended to be qualified under
         Section 401(a) of the Code has been determined to be so qualified by
         the Internal Revenue Service and nothing has occurred since the
         effective date of the last such determination which resulted in or is
         likely to result in the revocation of such determination.

                  (e) No reportable event (as defined in Section 4043 of ERISA)
         has occurred with respect to any Employee Benefit Plan and FirstFederal
         has not engaged in any transaction with respect to the Employee Benefit
         Plans which would subject FirstFederal to a tax, penalty or liability
         for prohibited transactions under ERISA or the Code nor have any of
         FirstFederal's directors, officers, or employees to the extent they or
         any of them are fiduciaries with respect to such plans, breached any of
         their responsibilities or obligations under Title I of ERISA.

                  (f) FirstFederal has furnished First Shenango with true and
         complete copies of: (i) all Employee Benefit Plans as in effect,
         together with all amendments thereto which will become effective at a
         later date; (ii) the most recent Internal Revenue Service determination
         letter issued with respect to each Employee Benefit Plan; and (iii)
         Form 5500 for the most recent completed fiscal year for each Employee
         Benefit Plan required to file such form.

                  (g) There are no material actions, suits or claims pending or
         threatened, against the Assets of any Employee Benefit Plan.

                  (h) The plans are qualified under Code Section 401 and the
         associated trust funds are exempt from tax under Code Section 501.

                  (i) Each Employee Benefit Plan which FirstFederal maintains
         has at all times been administered in material compliance with all
         applicable requirements of ERISA, including all reporting requirements,
         with respect to the Internal Revenue Service, the Department of Labor
         and the Pension Benefit Guaranty Corporation and including all
         disclosure requirements with respect to plan participants and
         beneficiaries.

                  (j) FirstFederal does not maintain nor is it under any
         obligation or duty to establish any type of post retirement benefit,
         medical, or life insurance plan for its employees.

         4.15 REAL PROPERTY. In addition to the representations and warranties
contained in Section 4.16, FirstFederal Financial hereby makes the following
additional representations, warranties and covenants to and with First Shenango
regarding the Real Property owned or leased by FirstFederal as listed on Section
4.15 of the Disclosure Schedule:

                  (a) Section 4.15(a) of the Disclosure Schedule contains a true
         and correct list of (i) each parcel of Real Property owned by
         FirstFederal, (ii) each parcel of Real Property leased by FirstFederal
         (as lessor or lessee), and (iii) all Liens relating to or affecting any

         Section 4.15(a) of


                                       32

<PAGE>   131



         the Disclosure Schedule, such Real Property owned by FirstFederal is
         free and clear of all Liens, pledges, equities, claims of others or
         restrictions whatsoever, except:

                           (i) Zoning and building ordinances and regulations
                  which do not prohibit or restrict the present use of the Real
                  Property;

                           (ii) Real estate taxes and assessments, both general
                  and special, which may be a Lien but are not yet due and
                  payable as of the Closing Date;

                           (iii) Easements, covenants, agreements, encumbrances,
                  conditions, reservations, restrictions of record or other
                  exceptions affecting the real estate, if any, which are
                  disclosed to First Shenango and approved in writing by First
                  Shenango prior to the Closing Date.

         FirstFederal has adequate rights of ingress and egress with respect to
         such Real Property, buildings, structures, facilities, fixtures and
         other improvements. FirstFederal has not received any notice or has
         Knowledge that the Real Property, as currently used by FirstFederal, is
         in violation of any applicable federal, state or local statute,
         ordinance, order, requirement, law, rule or regulation (including
         without limitation, building, zoning or Environmental Laws) affecting
         the Real Property, or that would have a Material Adverse Effect on the
         value of the Real Property or its continued operation and use in the
         ordinary course of business.

                  (b) The zoning of the Real Property permits the presently
         existing improvements and the conduct and continuation of the business
         presently being conducted on such Real Property.

                  (c) FirstFederal has a valid and subsisting leasehold estate
         in and the right to quiet enjoyment of the Real Property leased by it
         for the full term of the lease thereof. Each lease is a legal, valid
         and binding agreement, enforceable in accordance with its terms, of
         FirstFederal and of each other person that is a party thereto, and
         except as set forth in Section 4.15(c) of the Disclosure Schedule,
         there is no, and FirstFederal has not received notice of any default
         (or any condition or event which, after notice or lapse of time or
         both, would constitute a default) thereunder. None of the leases will
         terminate or lapse by reason of the transactions contemplated by this
         Merger Agreement.

                  (d) Except as disclosed in Section 4.15(d) of the Disclosure
         Schedule, the improvements on the Real Property are structurally sound
         and in good operating condition and in a state of good maintenance and
         repair, are adequate and suitable for the purposes for which they are
         presently being used and, to the Knowledge of FirstFederal, there are
         no condemnation or appropriation proceedings pending or threatened
         against any of such Real Property or the improvements thereon.

         4.16 ASSETS. With respect to the Assets:

         affecting its Assets with respect to health, safety and environmental
         and pollution control, including the disposition of hazardous or toxic
         waste materials or emissions into the air, soil or water, or any form
         of contamination that would have a Material Adverse Effect on the value
         of the Assets or the continued use of the Assets by FirstFederal in the
         ordinary course of business.

                  (b) Except as provided in Section 4.16(b) of the Disclosure
         Schedule, FirstFederal has good and marketable title to the Assets,

         equities, claims of others or restrictions whatsoever.

                  (c) All equipment owned by FirstFederal is now in good working
         condition and, as of the Closing Date, will be in good working
         condition with no material defects other than those items identified to
         First Shenango in Section 4.16(c) of the Disclosure Schedule, and
         except as disclosed in Section 4.16(c) of the Disclosure Schedule, no
         expenditures in excess of $100,000.00 are planned for the routine,
         normal maintenance of such equipment. Except as stated in Section
         4.16(c) of the Disclosure Schedule, no personal property used by
         FirstFederal in connection with its business is held under any lease,
         security agreement, conditional sales contract, or other title
         retention or security arrangement, or is other than in the possession
         and under the control of FirstFederal. The tangible personal property
         reflected in those Books and Records constitutes all such tangible
         personal property necessary for the conduct by FirstFederal of its
         business as now conducted.

         4.17 INTELLECTUAL PROPERTY. Except as previously disclosed,
FirstFederal or a Subsidiary owns the entire right, title and interest in and
to, or has valid licenses with respect to, all of the Intellectual Property
necessary to conduct the business and operations of FirstFederal and the
FirstFederal Subsidiaries as presently conducted. None of such Intellectual
Property is subject to any outstanding order, decree, judgment, stipulation,
settlement, lien, charge, encumbrance or attachment, which order, decree,
judgment, stipulation, settlement, lien, charge, encumbrance or attachment would
have a Material Adverse Effect on FirstFederal.

                  terminated within 360 calendar days after giving notice of
                  termination without resulting in any material cost or penalty
                  to FirstFederal or any Subsidiary.

                  (b) Each Contract required to be disclosed in Section 4.18(a)
         of the Disclosure Schedule is in full force and effect and constitutes
         a legal, valid and binding agreement, enforceable in accordance with
         its terms, of each party thereto; and except as disclosed in Section
         4.18(b) of the Disclosure Schedule neither FirstFederal, nor, to the
         Knowledge of FirstFederal, any other party to such Contract, is or has
         received notice that it is, in violation or breach of or default under
         any such Contract (or with notice or lapse of time or both, would be in
         violation or breach of or default under any such Contract). None of the
         Contracts disclosed in Section 4.18(a) of the Disclosure Schedule will
         terminate or lapse by reason of the transactions contemplated by this
         Merger Agreement.

                  (c) Except as disclosed in Section 4.18(c) of the Disclosure
         Schedule, FirstFederal is not a party to or bound by any Contract that
         has been or could reasonably be expected to have, individually or in
         the aggregate with any other such Contracts, a Materially Adverse
         Effect on FirstFederal.

                  (d) Except as disclosed in Section 4.18(d) of the Disclosure
         Schedule and any other Section of the Disclosure Schedule, there are no
         Contracts, commitments, leases, permits or other instruments necessary
         to hold the Assets by FirstFederal, as and where now held by
         FirstFederal, or to conduct the business of FirstFederal, as and where
         now operated by FirstFederal, or related to the operation or management
         of the Assets.

         4.19 POOLING OF INTERESTS. Except as set forth in Section 4.19 of the
Disclosure Schedule, as of the date of this Merger Agreement, FirstFederal knows
of no reason relating to it which would reasonably cause it to believe that the
Merger will not qualify as a pooling of interests for financial accounting
purposes.

         4.20 RESERVED.

         4.21 LICENSES. Except as disclosed in Section 4.21 of the Disclosure
Schedule:

                           (i) FirstFederal owns or validly holds all Licenses

                           (ii) each License of FirstFederal is valid, binding

                           (iii) FirstFederal has not received any notice that
                  it is in default (or with the giving of notice or lapse of

None of the Licenses of FirstFederal will terminate or lapse by reason of the
transactions contemplated by this Merger Agreement.

         4.22 INSURANCE. To the best of FirstFederal's Knowledge, FirstFederal

customarily insured, covering property damage and loss of income by fire or
other casualty including, but not limited to, occurrence- based general
liability insurance, and (ii) adequate insurance protection against all
Liabilities, claims and risks against which it is customary to insure. To
FirstFederal's Knowledge after due inquiry, except as disclosed in Section 4.22
of the Disclosure Schedule, there is no breach or default with respect to any
material provision contained in any policy or binder described in this provision
and there has not been any failure to give any notice or present any claim under
any such policy or binder in due or timely fashion. There are no outstanding
unpaid premiums, and there are no provisions for retrospective or retroactive
premium adjustments except as set forth in Section 4.22 of the Disclosure
Schedule, and FirstFederal has not received notice of any cancellations or
nonrenewal or disallowance of any claims under any such policy or binder.
Finally, except as disclosed in Section 4.22 of the Disclosure Schedule, there
has not been any instance since the formation of FirstFederal where there has
not been in full force and effect insurance policies providing the types of
insurance as described above. The insurance coverage provided by the policies
described in this section will not terminate or lapse by reason of the
transactions contemplated by this Merger Agreement.

         Bancorp, Inc.'s dividend in the quarter in which Closing occurs with
         the declaration and payment of FirstFederal Financial's dividend in
         such quarter so that the shareholders of First Shenango Bancorp, Inc.,
         receive only one dividend in the quarter in which Closing occurs;

                  (b) Directly or indirectly purchase, redeem, or otherwise

prohibit (i) First Shenango Bancorp, Inc., or the Thrift Subsidiary, as the case
may be, from furnishing information to, or entering into discussions or

                           or

                           (v) unless FirstFederal Financial is in breach of its
                           material obligations hereunder, at or prior to First
                           Shenango Bancorp, Inc.'s shareholders' meeting at
                           which the Merger is submitted for approval and voted

                  (b) As used in this Section, Beneficial Ownership shall have
         the meaning ascribed to it in Rule 13d-3 under the Exchange Act.

         5.1.14 CONFIDENTIALITY. Except as may be required by law, First
Shenango agrees that unless and until the Closing has been consummated, First
Shenango, its officers, directors, and other representatives, will hold in
strict confidence and will not use to the detriment of FirstFederal any data or
information contained in connection with this transaction or Merger Agreement
with respect to FirstFederal's business. If the transactions contemplated by

FirstFederal all such data and information that FirstFederal may reasonably
request that was made available to First Shenango in connection with this
transaction. This data and information does not include data and information
that is publicly available other than as a result of disclosure by First

the termination upon acquisition provisions specified under Section 8.2(c) of

termination, as of the Closing Date, of a defined benefit plan maintained by the
Thrift Subsidiary (the "Defined Benefit Plan"). First Shenango may amend the
Defined Benefit Plan to amend the benefit accruals or other provisions of the
Defined Benefit Plan provided that no amendments made to the Defined Benefit
Plan shall operate either to adversely affect the tax-favored


                                       44

status of the Defined Benefit Plan or result in any funding deficiencies of the
Defined Benefit Plan as of the date of the plan termination, or require an
additional contribution from First Shenango.

Thrift Subsidiary shall take all actions necessary to terminate the Directors'
Deferred Compensation Plan and the Supplemental Executive Retirement Plan for
the benefit of Mr. Bonadio, and all benefits under these plans shall be paid out
in a lump sum to each participant; or alternatively, on or before the Closing
Date, Thrift Subsidiary in its sole discretion may establish an irrevocable
grantor trust or trusts and deposit therein guaranteed investment contracts in
amounts sufficient to provide the monthly benefits specified in accordance with
the Directors Plan and the Supplemental Retirement Plan for such participants
and beneficiaries thereunder that do not receive the lump sum payment as of the
Closing Date. To the extent that any lump sum payments of benefits are not made
as of the Closing Date or that any monthly or other periodic payments of
benefits are not funded through the establishment of one or more irrevocable
grantor trusts as of Closing Date, FirstFederal shall assume liability
thereafter with respect to the payment of any benefits that may be attributable
to the plans described in this section.

         5.1.19 EMPLOYMENT AGREEMENTS. First Shenango will use its best efforts
to cause the Employment Agreements identified in Section 5.2.6 to be executed
and delivered.

Agreement, and any other documents or actions necessary to the consummation of
the Merger provided for herein pursuant to law. Subject only to (i)
FirstFederal's Board of Directors' review of FirstFederal's Registration
Statement to be filed with the SEC described in this subparagraph and its
reasonable satisfaction with the information set forth therein, and (ii) the
exercise of their fiduciary duties, the Board of Directors of FirstFederal
intends to inform the shareholders of FirstFederal in the proxy materials

FirstFederal intend to vote all shares of FirstFederal Common Stock which they

retained by FirstFederal shall receive the standard package of FirstFederal

president of Thrift Subsidiary shall receive the benefits to which he is
entitled under the supplemental executive retirement plan adopted by the Thrift
Subsidiary for his benefit; this Section 5.2.3 shall be construed as an
agreement as to which the president of Thrift Subsidiary is intended to be a
third party beneficiary and shall be enforceable by him and his heirs and
representatives.

agrees that unless and until the Closing has been consummated, FirstFederal, its
officers, directors, and other representatives, will hold in strict confidence

                  (a) The merger between First Shenango Bancorp, Inc., and
         FirstFederal Financial is intended to be structured to qualify for
         treatment under present accounting


                                       46

<PAGE>   145



         rules as a pooling of interests, and First Shenango and FirstFederal
         agree to take no action which would disqualify this treatment under
         GAAP.

                  (b) FirstFederal and First Shenango shall cooperate and use
         their best efforts to identify those persons who may be deemed to be
         "affiliates" of FirstFederal or First Shenango within the meaning of
         Rule 145 promulgated by the SEC under the Securities Act and for
         purposes of qualifying the Merger for "pooling of interests" accounting
         treatment. FirstFederal and First Shenango shall use its respective
         best efforts to cause each person so identified to deliver to
         FirstFederal or First Shenango, as the case may be, no later than 30
         days prior to the Effective Time, a written agreement (which agreement
         shall be mutually satisfactory to counsel for FirstFederal and First
         Shenango). Shares of FirstFederal Common Stock issued to such
         FirstFederal and First Shenango affiliates in exchange for First
         Shenango Common Stock or previously owned by them shall not be

         Shenango Bancorp, Inc., have been published within the meaning of
         Section 201.01 of the SEC's Codification of Financial Reporting
         Policies, regardless of whether each such affiliate has provided the
         written agreement referred to in this section.

                  (c) FirstFederal Financial shall use its best efforts to
         publish no later than ninety (90) days after the end of the first month
         after the Effective Time in which there are at least thirty (30) days
         of post-Merger combined operations (which month may be the month in
         which the Effective Time occurs), combined sales and net income figures
         as contemplated by and in accordance with the terms of SEC Accounting
         Series Release No. 135.

FirstFederal will provide copies of all correspondence, comments, amendments and
other material filed with, or received from the SEC, and FirstFederal will

of any stop order, of the suspension of qualification of the FirstFederal Common
Stock issuable in connection with the Merger for offering or sale in any

                                       47

thereof, at the time of the First Shenango Bancorp, Inc., shareholders' meetings
or, in the case of the Registration Statement, at the time it becomes effective
and at the Effective Time, contain any untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

         5.3.4 APPLICATIONS. As promptly as practicable after the date hereof,
First Shenango and FirstFederal shall cooperate in the preparation and

         association or other business or professional entity whose consent or
         approval is required for consummation of the transactions contemplated
         hereby, provided that First Shenango Bancorp, Inc., shall not agree to

         which consent shall not be unreasonably withheld and (2) requesting the
         delivery of appropriate opinions, consents and letters from its counsel
         and independent auditors. No party hereto shall take or fail to take,

         best of its ability permit to be taken or omitted to be taken by any
         third persons, any action that would substantially impair the prospects

         materially delay such completion, or that would adversely affect the
         qualification of the Merger for pooling of interests accounting
         treatment or as a reorganization within the meaning of Section 368(a)
         of the Code. In the event that either party has taken any action,

         other party may reasonably request to cure such effect to the extent
         curable without a Material Adverse Effect on either of the parties
         within 30 days of such request.

         FirstFederal Financial, and FirstFederal Financial shall give prompt
         notice to First Shenango Bancorp, Inc., of (i) the occurrence, or
         failure to occur, of any event which occurrence or failure would be
         likely to cause any representation or warranty contained in this
         Agreement to be untrue or inaccurate in any material respect at any
         time from the date hereof to the Closing Date and (ii) any material
         failure of FirstFederal or First Shenango, as the case may be, to
         comply with or satisfy any covenant, condition or agreement to be
         complied with or satisfied by it hereunder, and each party shall use
         all reasonable efforts to remedy such failure.

         provide the other party with such historical financial information
         regarding it (and related audit reports and

         shall be pending against either party on the Closing Date that could
         result in a judgment, decree, or order that would prevent or make
         unlawful the carrying out of this Merger Agreement;

                  (h) By FirstFederal after Regulatory Approval if the
         conditions precedent to FirstFederal's obligation to close as contained
         in Article VI have not been satisfied or waived;


                  (i) By First Shenango after Regulatory Approval if the
         conditions precedent to First Shenango's obligation to close as
         contained in Article VII have not been satisfied or waived;

                  (j) By First Shenango if all of the following occur: (i) the
         FirstFederal Share Price Change is greater than 15%; (ii) the
         FirstFederal Share Price Change is greater than the SNL Share Price
         Change by more than .1%; and (iii) the FirstFederal Share Price Change
         is a positive number.

         12.2 EFFECT OF TERMINATION. If this Merger Agreement is validly
terminated pursuant to Section 12.1, this Merger Agreement will forthwith become
null and void, and there will be


                                       56

<PAGE>   155



no liability or obligation on the part of First Shenango or FirstFederal (or any
of their respective officers, directors, employees, agents or other
representatives of Affiliates), except as provided in Sections 5.1.13 and 12.3
and except that the provisions of the Confidentiality Agreements entered into by
FirstFederal on January 13, 1998 will continue to apply following any such
termination.

         12.3 LIQUIDATED DAMAGES. In the event this Merger Agreement is
terminated pursuant to 12.1(d), (e), (g), (h) or (i) and the nonterminating
party is in material breach of this Merger Agreement, the terminating party
shall be entitled to receive as liquidated damages the sum of $3 million
("Liquidated Damages") payable within 30 days of the effective date of the
termination. The parties agree that the Liquidated Damages is not a penalty and
is a reasonable estimate of the damages that would be sustained by the
terminating party, as it would be difficult to determine the extent of damages
at the time of the termination. Nothing contained herein shall limit or alter
the rights of FirstFederal to receive a break-up fee under Section 5.1.13,
except that the aggregate amount payable to FirstFederal under Sections 5.1.13
and 12.3 shall not exceed $3 million.

seven days of the date of this Agreement in the event that the accompanying
documentation relating to Section 3.12 of the Disclosure Schedule contain
information that would have Material Adverse Impact on First Shenango or a

                                  May 8, 1998


Board of Directors
FirstFederal Financial Services Corp
135 East Liberty Street
P.O. Box 385
Wooster, OH 44691

Members of the Board:

     You have requested our opinion as investment bankers as to the fairness,
from a financial point of view, to the shareholders of FirstFederal Financial
Services Corp. ("FirstFederal") of the exchange ratio in the proposed merger
(the "Merger") of FirstFederal with First Shenango Bancorp, Inc. ("First
Shenango"), pursuant to the Agreement and Plan of Merger dated as of February 8,
1998 between FirstFederal and First Shenango (the "Agreement"). Under the terms
of the Merger, each outstanding share of common stock of First Shenango will be
exchanged for 1.143 shares of common stock of FirstFederal (the "Exchange
Ratio"). It is our understanding that the Merger will be accounted for as a
pooling-of-interests under generally accepted accounting principles.

     Keefe, Bruyette & Woods, Inc. as part of its investment banking business is
continually engaged in the valuation of banking businesses and their securities
in connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes. As
specialists in the securities of banking companies we have experience in, and
knowledge of, the valuation of banking enterprises. In the ordinary course of
our business as a broker-dealer, we may, from time to time, purchase securities
from, and sell securities to, FirstFederal and as a market maker in securities
we may from time to time have a long or short position in, and buy or sell, debt
or equity securities of FirstFederal for our own account and for the accounts of
our customers. To the extent we have any such position as of the date of this
opinion it has been disclosed to FirstFederal. We have acted as a financial
advisor to the Board of Directors of FirstFederal in rendering this fairness
opinion and will receive a fee from FirstFederal for our services.

     In connection with this opinion, we have reviewed, among other things, the
Agreement; the Registration Statement on Form S-4, Annual Reports to
Stockholders of FirstFederal and First Shenango for the three years ended
September 30, 1997; certain interim reports to stockholders and Quarterly
Reports on Form 10-Q of First Shenango and FirstFederal, and certain internal
financial analyses and forecasts for FirstFederal and First First Shenango
prepared by management. We also have held discussions with members of the senior
management of FirstFederal and First Shenango
<PAGE>   160



Board of Directors
FirstFederal Financial Services Corp.

regarding the past and current business operations, regulatory relationships,
financial condition and future prospects of their respective companies. In
addition, we have compared certain financial and stock market information for
FirstFederal and First Shenango with similar information for certain other
companies the securities of which are publicly traded, reviewed the financial
terms of certain recent business combinations in the banking industry and
performed such other studies and analyses as we considered appropriate.

     In conducting our review and arriving at our opinion, we have relied upon
and assumed the accuracy and completeness of all of the financial and other
information provided to us or publicly available and we have not assumed any
responsibility for independently verifying any of such information. We have
relied upon the management of FirstFederal as to the reasonableness and
achievability of the financial and operating forecasts and projections (and the
assumptions and bases therefor) provided to us, and we have assumed that such
forecasts and projections reflect the best currently available estimates and
judgments of FirstFederal and that such forecasts and projections will be
realized in the amounts and in the time periods currently estimated by such
management. We have also assumed that the aggregate allowances for loan losses
for FirstFederal and First Shenango are adequate to cover such losses. In
rendering our opinion, we have not made or obtained any evaluations or
appraisals of the property of FirstFederal or First Shenango, nor have we
examined any individual credit files.

     We have considered such financial and other factors as we have deemed
appropriate under the circumstances, including among others the following: (i)
the historical and current financial position and results of operations of
FirstFederal and First Shenango; (ii) the assets and liabilities of FirstFederal
and First Shenango; and (iii) the nature and terms of certain other merger
transactions involving banks and bank holding companies. We have also taken into
account our assessment of general economic, market and financial conditions and
our experience in other transactions, as well as our experience in securities
valuation and our knowledge of the banking industry generally. Our opinion is
necessarily based upon conditions as they exist and can be evaluated on the date
hereof and the information made available to us through the date hereof.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Exchange Ratio in the Merger is fair, from a financial point of
view, to the common stockholders of FirstFederal.

                                             Very truly yours,

                                             /s/ Keefe, Bruyette & Woods, Inc.

Board of Directors
First Shenango Bancorp, Inc.
25 North Mill Street
New Castle, PA 16103

Gentlemen:

         You have requested our opinion with respect to the fairness, from a
financial point of view, as of the date hereof, to the holders of common stock,
par value $0.10 per share ("First Shenango Common Stock"), of First Shenango
Bancorp, Inc. ("First Shenango") of the exchange ratio as set forth in Section
2.5 (a) of the Agreement of Affiliation and Plan of Merger dated February 6,
1998, by and between FirstFederal Financial Services Corp ("FirstFederal"), and
First Shenango.

         The Agreement of Affiliation and Plan of Merger dated February 6, 1998
(the "Agreement") provides for the merger (the "Merger") of First Shenango with
and into FirstFederal, pursuant to which, among other things, at the Effective
Time (as defined in the Agreement), outstanding shares of First Shenango Common
Stock will be exchanged for 1.143 shares of common stock, par value $1.00 per
share ("FirstFederal Common Stock") of FirstFederal, as set forth in Section 2.5
(a) of the Agreement (the "Exchange Ratio"). The terms and conditions of the
Merger are more fully set forth in the Agreement.

         McDonald & Company Securities, Inc., as part of its investment banking
business, is customarily engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.

         We have acted as First Shenango's financial advisor in connection with,
and have participated in certain negotiations leading to, the execution of the
Agreement. In connection with rendering our opinion set forth herein, we have
among other things:

         (i)      Reviewed First Shenango's Annual Reports to Shareholders and
                  Annual Reports on Form 10-K for each of the years ended
                  December 31, 1997, December 31, 1996, and December 31, 1995,
                  including the audited financial statements contained therein;

         (ii)     Reviewed FirstFederal's Annual Reports to Shareholders and
                  Annual Reports on Form 10-K for each of the years ended
                  December 31, 1997, December 31, 1996 and December 31, 1995,
                  including the audited financial statements contained therein;

         (iii)    Reviewed certain other public and non-public information,
                  primarily financial in nature, relating to the respective
                  businesses, earnings, assets and prospects of First Shenango
                  and FirstFederal provided to us or publicly available;

         (iv)     Participated in meetings and telephone conferences with
                  members of senior management of First Shenango and
                  FirstFederal concerning the financial condition, business,
                  assets, financial forecasts and prospects of the respective
                  companies, as well as other matters we believed relevant to
                  our inquiry;

         (v)      Reviewed certain stock market information for First Shenango
                  Common Stock and FirstFederal Common Stock, and compared it
                  with similar information for certain companies, the securities
                  of which are publicly traded;

         (vi)     Compared the results of operations and financial condition of
                  First Shenango and FirstFederal with that of certain companies
                  which we deemed to be relevant for purposes of this opinion;

         (vii)    Reviewed the financial terms, to the extent publicly
                  available, of certain acquisition transactions which we deemed
                  to be relevant for purposes of this opinion;

         (viii)   Reviewed the Agreement and its schedules and exhibits and
                  certain related documents; and

                  (i)      Performed such other reviews and analyses as we have 
                           deemed appropriate.

      In our review and analysis and in arriving at our opinion, we have assumed
    and relied upon the accuracy and completeness of all of the financial and
    other information reviewed by us and have relied upon the accuracy and
    completeness of the representations, warranties and covenants of First
    Shenango and FirstFederal contained in the Agreement. We have not been
    engaged to undertake, and have not assumed any responsibility for, nor have
    we conducted, an independent investigation or verification of such matters.
    We have not been engaged to and we have not conducted a physical inspection
    of any of the assets, properties or facilities of either First Shenango or
    FirstFederal nor have we made or obtained or been furnished with any
    independent valuation or appraisal of any of such assets, properties or
    facilities or any of the liabilities of either First Shenango or
    FirstFederal. With respect to financial forecasts used in our analysis, we
    have assumed that such forecasts have been reasonably prepared by management
    of First Shenango and FirstFederal, as the case may be, on a basis
    reflecting the best currently available estimates and judgments of the
    management of First Shenango and FirstFederal, as to the future performance
    of First Shenango, FirstFederal and First Shenango and FirstFederal
    combined, as the case may be. We have not been engaged to assess the
    reasonableness or achievability of such financial forecasts or the
    assumptions on which they are based, and we express no view as to such
    financial forecasts or assumptions. We have also assumed that all of the
    conditions to the consummation of the Merger, as set forth in the Agreement,
    including the tax-free nature of the reorganization for federal income tax
    purposes, would be satisfied and that the Merger would be consummated on a
    timely basis in the manner contemplated by the Agreement.

    We will receive a fee for our services as financial advisor to First
    Shenango, a substantial portion of which is contingent upon closing of the
    Merger. We will also receive a fee for our services in rendering this
    opinion.

    In the ordinary course of business, we may actively trade securities of
    First Shenango or FirstFederal for our own account and for the accounts of
    customers and, accordingly, we may at any time hold a long or short position
    in such securities. In addition, McDonald & Company has provided investment
    banking services to FirstFederal in the past, including the March 1997
    private placement of subordinated notes, and may provide such services to
    FirstFederal in the future.

    This opinion is based on economic and market conditions and other
    circumstances existing on, and information made available as of, the date
    hereof. In addition, our opinion is, in any event, limited to the fairness,
    as of the date hereof, from a financial point of view, of the Exchange Ratio
    to the holders of First Shenango Common Stock, and does not address the
    underlying business decision by First Shenango's Board of Directors to
    effect the Merger, does not compare or discuss the relative merits of any
    competing proposal or any other terms of the Merger, and does not


<PAGE>   164

    constitute a recommendation to any First Shenango shareholder as to how such
    shareholder should vote with respect to the Merger. This opinion does not
    represent an opinion as to what the value of First Shenango Common Stock or
    FirstFederal Common Stock may be at the Effective Time of the Merger or as
    to the prospects of First Shenango's business or FirstFederal's business.

    This opinion is directed to and has been prepared for the confidential use
    of the Board of Directors of First Shenango. This opinion shall not be
    reproduced, summarized, described or referred to or given to any other
    person without our prior written consent. Notwithstanding the foregoing,
    this opinion may be included in the proxy statement to be mailed to the
    holders of First Shenango Common Stock in connection with the Merger,
    provided that this opinion will be reproduced in such proxy statement in
    full, and any description of or reference to us or our actions, or any

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), 1932(c) or

         (i) listed on a national securities exchange; or

right to obtain payment of the fair value of any such shares under this

         (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 corporation or solely into
such shares and money in lieu of fractional shares.

         (ii) Shares of any preferred or special class unless the articles, the
plan or the terms of the transaction entitle all shareholders of the class to
vote thereon and require for the 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.

         (iii) Shares entitled to dissenters rights under section 1906(c)

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 shareholder 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;.

applicable to any transaction described in any statute other than this part that
makes reference to this subchapter for the purpose of granting dissenters
rights.

         (f) Certain provisions of articles ineffective.-This subchapter may not
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)
and 2512 (relating to dissenters rights procedure).

         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 the purposes 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 the
circumstances, taking into account all relevant factors, including the average
rate currently paid by the corporation on its principal bank loans.

         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


<PAGE>   167



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.

         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.

         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.

         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 


<PAGE>   168


(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.

         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.

         (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 so 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 that the original dissenter had after
making demand for payment of their fair value.

         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


<PAGE>   169



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.

         1579 VALUATION PROCEEDING GENERALLY.-(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.

         (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.

         1580 COSTS AND EXPENSES OF VALUATION PROCEEDINGS.-(a) General rule.-
The costs and expenses of any proceedings 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 as the court deems
appropriate 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


<PAGE>   170



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 benefitted.
