Wooster, OH  44691

Ladies and Gentlemen:

         We have acted as counsel to FirstFederal Financial Services Corp, an
Ohio corporation ("FirstFederal"), in connection with the proposed merger of
First Shenango Bancorp, Inc., a Pennsylvania corporation ("First Shenango"),
with and into FirstFederal, with FirstFederal as the surviving entity (the
"Merger"). The Merger will be effected pursuant to the Agreement of Affiliation
and Plan of Merger and by and between FirstFederal and First Shenango dated as
of February 6, 1998 (the "Agreement").

         In our capacity as counsel to FirstFederal, our opinion has been
requested with respect to certain of the federal income tax consequences of the
proposed Merger. In rendering this opinion, we have examined: i) the Internal
Revenue Code of 1986 as amended (the "Code") and Treasury Regulations
promulgated thereunder and ii) appropriate Internal Revenue Service and court
decisional authority (collectively "Tax Authority"). In addition, we have relied
upon certain information made known to us as more fully described below.

         Capitalized terms used but not otherwise defined herein have the
respective meanings given to them in the Agreement.

         In arriving at the opinions expressed below, we have examined and
relied on the originals or copies certified or otherwise identified to our
satisfaction of i) the Agreement, and the exhibits and schedules thereto; ii)
the Registration Statement on Form S-4 filed with the Securities and Exchange
Commission by FirstFederal in connection with the Merger; iii) the Prospectus
and Proxy Statement ("Prospectus"); iv) such corporate records of FirstFederal
and First Shenango as we have deemed appropriate.

         Based upon and subject to the limitations and qualifications expressly
set forth herein, it is our opinion that under current applicable law, the
Merger will constitute a reorganization within the meaning of Section 368 of the
Code and that accordingly, the following will be the material federal income tax
consequences of the Merger:

         1.       No gain or loss will be recognized by FirstFederal or First
                  Shenango by reason of the Merger.

         2.       No gain or loss will be recognized by any First Shenango
                  shareholder upon the exchange of First Shenango Common Stock
                  solely for FirstFederal Common Stock in the Merger (except in
                  connection with the receipt of cash in lieu of a fractional
                  share of FirstFederal Common Stock or in connection with the
                  exercise of dissenter's rights, as discussed below).

         3.       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 will be the same as the aggregate tax basis of the
                  First Shenango Common Stock surrendered in exchange therefor
                  (subject to any adjustments required as a result of the
                  receipt of cash in lieu of a fractional share of FirstFederal
                  Common Stock).

         4.       The holding period of the shares of FirstFederal Common Stock
                  received by a First Shenango shareholder in the Merger will
                  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).

         5.       Cash received in the Merger by a First Shenango shareholder in
                  lieu of a fractional share interest of FirstFederal Common
                  Stock will 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 will
                  qualify as a capital gain or loss (assuming the First Shenango
                  Common Stock surrendered in exchange thereof will be held as a
                  capital asset by such shareholder at the Effective Time).

         6.       A First Shenango shareholder who receives only cash as a
                  result of the exercise of dissenter's rights will 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 will be recognized for
                  federal income tax purposes and will 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 will 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 the dividend will 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.

         This opinion may not be applicable to First Shenango's shareholders who
are banks, insurance companies, tax exempt organizations, non-United States
shareholders or dealers in securities, or who received their First Shenango
stock pursuant to the exercise of employee stock options or otherwise as
compensation.

         We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement and to the
reference of this opinion under the "Summary: Certain Federal Income Tax
Consequences of the Merger," the "The Merger: Certain Federal Income Tax
Consequences of the Merger" and elsewhere in the Prospectus.

         This opinion is subject to the following assumptions, exceptions and
qualifications:

         A. The opinions set forth above in paragraphs 1 through 6 are limited
to the matters expressly set forth in this opinion letter and no opinion is to

         B. We have relied without independent verification of the statements
contained therein on officers' certificates of First Shenango and FirstFederal,
each dated the date hereof containing representations as to certain tax and
factual matters. We have also assumed that the parties to the Merger will act

merger under the applicable laws of the State of Ohio, the Commonwealth of
Pennsylvania and the United States. We

express no opinions as to the laws of any jurisdiction other than the income tax
laws of the United States.

         C. We have assumed without independent verification, that:

                  (i) All documents submitted to us as originals or duplicate
         originals are authentic;

                  (ii) All documents submitted to us as copies, whether
         certified or not, conform to authentic original documents;

                  (iii) All signatures of persons signing all documents examined
         in connection with this opinion are genuine;

                  (iv) All parties to the documents reviewed by us (other than
         FirstFederal) have full power and authority to execute, deliver and
         perform their obligations under such documents, and under the documents
         required or permitted to be delivered and performed under the documents
         reviewed by us, and all such documents have been duly authorized by all
         necessary corporate or other action on the part of such parties.

         D. We disclaim any undertaking to update this letter or otherwise
advise you of any changes of law or fact which may hereafter be brought to our
attention. The Tax Authority is subject to change, possibly with retroactive
effect, and any change would affect the continuing validity of the discussion
contained in this letter of the federal income tax consequences of the proposed
Merger.
