Dear Stockholder:

      You are cordially invited to attend the Special Meeting of Stockholders
(the "Special Meeting") of PennFirst Bancorp, Inc. ("PennFirst"), which will be
held at the Connoquenessing Country Club located at RD #2, Route 65, Ellwood
City, Pennsylvania, on Tuesday, March 18, 1997 at 10:00 a.m., Eastern Time.

      At the Special Meeting, stockholders will be asked to approve the
Agreement and Plan of Reorganization and a related Agreement of Merger, both
dated as of September 16, 1996 (together, the "Merger Agreement"), whereby Troy
Hill Bancorp, Inc. ("THB") will be merged into PennFirst (the "Merger"), with
PennFirst as the surviving corporation. If the Merger is consummated, each share
of common stock of THB, par value $.01 per share ("THB Common Stock"),
outstanding immediately prior to consummation of the Merger (other than shares
as to which dissenters' rights have been asserted and duly perfected in
accordance with Pennsylvania law and shares held by THB, PennFirst or any of
their respective subsidiaries) shall be converted into and represent the right
to receive either (i) $21.15 in cash or (ii) a number of shares of PennFirst
common stock, par value $.01 per share ("PennFirst Common Stock"), with a value
equal to $21.15, as determined by applying a formula (the "Exchange Ratio") set
forth in the Merger Agreement and based on the average market price ("Average
Share Price") of PennFirst Common Stock over the 20 trading day period ending on
the date PennFirst and THB receive all requisite regulatory approvals and
satisfy all applicable waiting periods related to the Merger, subject to the
terms, conditions, limitations and procedures set forth in the Merger Agreement
("Merger Consideration").

      As a result of the Merger, Troy Hill Federal Savings Bank ("Troy Hill"), a
wholly-owned subsidiary of THB, will become a wholly-owned subsidiary of
PennFirst. Approval by PennFirst's stockholders of the Merger Agreement, which
involves the issuance of new shares of PennFirst Common Stock in connection with
the Merger, is a condition to consummation of the Merger. The terms of the
proposed Merger are explained in detail in the accompanying Joint Proxy
Statement/Prospectus, which we urge you to read carefully.

      THE BOARD OF DIRECTORS OF PENNFIRST HAS UNANIMOUSLY APPROVED THE MERGER
AND RECOMMENDS THAT YOU VOTE IN FAVOR OF THE MERGER.

      Enclosed is a Notice of Special Meeting of Stockholders, the Joint Proxy
Statement/Prospectus, a proxy card and, for PennFirst, its 1995 Annual Report to
Stockholders and Form 10-Q for the quarter ended September 30, 1996. Your vote
is important, regardless of the number of shares you own. Please complete, sign
and date the enclosed proxy card and return it as soon as possible in the
envelope provided. If you decide to attend the meeting, you may vote your shares
in person whether or not you have previously submitted a proxy. On behalf of the
Board, I thank you for your attention to this important matter.

The Stockholder Meetings

      PennFirst. The PennFirst Special Meeting will be held at the
Connoquenessing Country Club located at RD #2, Route 65, Ellwood City,
Pennsylvania on March 18, 1997 at 10:00 a.m., Eastern Time. Only the holders of
record of the outstanding shares of PennFirst Common Stock at the close of
business on January 23, 1997 (the "PennFirst Record Date") are entitled to
notice of and to vote at the PennFirst Special Meeting. At the PennFirst Record
Date, 3,901,780 shares of PennFirst Common Stock were outstanding and entitled
to vote. A majority of the outstanding shares of PennFirst Common Stock must be
represented in person or by proxy at the PennFirst Special Meeting in order for
a quorum to be present. Each share of PennFirst Common Stock entitles the holder
thereof to one vote on each matter to be submitted to PennFirst's stockholders
at the PennFirst Special Meeting.

      At the PennFirst Special Meeting, PennFirst's stockholders will be asked
to consider and vote upon (a) a proposal to approve the Merger Agreement and (b)
the transaction of such other business as may properly come before the PennFirst
Special Meeting and any adjournment or adjournments thereof. The affirmative
vote of a majority of the votes cast by all stockholders entitled to vote
thereon at the PennFirst Special Meeting is required to adopt and approve the
Merger Agreement. Shares as to which the "ABSTAIN" box has been marked on the
proxy and shares held by brokers in street name for customers for which voting
instructions have not been received ("broker non-votes") will be counted as
present for determining if a quorum is present; however, such abstentions and
broker non-votes are not considered votes cast and thus will not affect the
number of votes required for approval. See "Stockholder Meetings - Special
Meeting of PennFirst Stockholders."

      As of the PennFirst Record Date, the directors and executive officers of
PennFirst and their affiliates in the aggregate beneficially owned 434,676
shares, or 11.14%, of the outstanding PennFirst Common Stock, excluding shares
subject to options.

      Revocability of Proxies. Holders of PennFirst Common Stock may revoke a
proxy at any time prior to its exercise by filing with the Secretary of
PennFirst (Frank D. Martz, Secretary, 600 Lawrence Avenue, Ellwood City,
Pennsylvania 16117) a written notice of revocation or a proxy bearing a later
date, or by voting in person at the PennFirst Special Meeting. Attendance at the
PennFirst Special Meeting will not of itself constitute revocation of a proxy.
If your shares are not registered in your own name, you will need additional
documentation from your recordholder in order to vote personally at the
PennFirst Special Meeting.

quorum to be present. Each share of THB Common Stock entitles the holder thereof
to one vote on each matter to be submitted to THB's stockholders at the THB
Special Meeting.

and vote upon (a) a proposal to approve the Merger Agreement and (b) the
transaction of such other business as may properly come before the THB Special
Meeting and any adjournment or adjournments thereof. The proposal to approve the
Merger Agreement will require the affirmative vote of a majority of the votes
cast by all stockholders of THB entitled to vote thereon at the THB Special
Meeting. Shares as to which the "ABSTAIN" box have been marked on the proxy and
broker non-votes will be counted as present for determining if a quorum is
present; however, such abstentions and broker non-votes are not considered votes
cast and thus will not affect the number of votes required for approval. See
"Stockholder Meetings - Special Meeting of THB Stockholders."

      The directors and certain officers of THB have agreed and intend to vote
or cause to be voted all shares of THB Common Stock in which they have the right
to vote for approval and adoption of the Merger Agreement. At the THB Record
Date, directors and executive officers of THB and their affiliates in the

any time prior to its exercise by filing with the Secretary of THB (Nancy H.
Kufner, Secretary, 1706 Lowrie Street, Pittsburgh, Pennsylvania 15212) a written
notice of revocation or a proxy bearing a later date, or by voting in person at
the THB Special Meeting. Attendance at the THB Special Meeting will not of
itself constitute revocation of a proxy. If your shares are


                                      -10-
<PAGE>

not registered in your own name, you will need additional documentation from
your recordholder in order to vote personally at the THB Special Meeting.

      HOLDERS OF THB COMMON STOCK ARE REQUESTED TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID
ENVELOPE, EVEN IF THEY ARE PLANNING TO ATTEND THE THB SPECIAL MEETING. ALL
PROPERLY EXECUTED PROXIES RECEIVED PRIOR TO OR AT THE THB SPECIAL MEETING WILL
BE VOTED WITH RESPECT TO THE MATTERS IDENTIFIED ON THE PROXY CARDS IN ACCORDANCE
WITH ANY INSTRUCTIONS THEREON AND, IF NO INSTRUCTIONS ARE GIVEN, WILL BE VOTED
FOR ADOPTION AND APPROVAL OF THE MERGER AGREEMENT.

Terms of the Merger

      In accordance with the terms of the Merger Agreement, THB will be merged
with and into PennFirst, with PennFirst as the surviving corporation of the
Merger. The Merger Agreement contemplates that, upon consummation of the Merger,
Troy Hill will be operated as a direct, wholly-owned subsidiary of PennFirst.

      The Merger Agreement provides that at the effective time of the Merger,
each share of THB Common Stock outstanding immediately prior to consummation of
the Merger (other than shares as to which dissenters' rights have been asserted
and duly perfected in accordance with Pennsylvania law and shares held by
PennFirst, THB or any of their respective subsidiaries) shall be converted into
and represent the right to receive either (i) $21.15 in cash ("Per Share Cash
Consideration") or (ii) a number of shares of PennFirst Common Stock with a
value equal to $21.15 ("Per Share Stock Consideration"), as determined by the
Exchange Ratio and based on the Average Share Price of PennFirst Common Stock
over the 20 trading day period ("Pricing Period") ending on the date PennFirst
and THB receive all requisite regulatory approvals and satisfy all applicable
waiting periods related to the Merger. The Exchange Ratio in the Merger
Agreement provides that the number of shares of PennFirst Common Stock
comprising the Per Share Stock Consideration shall be equal to the quotient
determined by dividing (x) $21.15 by (y) the Average Share Price during the
Pricing Period. The Merger Agreement also provides that 60% of the aggregate
Merger Consideration will consist of PennFirst Common Stock and the remaining
40% shall consist of cash. See "The Merger - The Merger Consideration."

      No fractional shares of PennFirst Common Stock will be issued in the
Merger to holders of THB Common Stock. Each holder of THB Common Stock who
otherwise would have been entitled to a fraction of a share of PennFirst Common
Stock shall receive in lieu thereof, at the time of surrender of the certificate
or certificates representing such holder's shares of THB Common Stock, an amount
of cash (without interest) determined by


                                      -11-
<PAGE>

multiplying the fractional share interest to which such holder would otherwise
be entitled by $21.15.

Opinions of THB's Financial Advisor

      The Board of Directors of THB has received a written opinion from Charles
Webb & Company, a Division of Keefe Bruyette & Woods, Inc. ("Webb"), dated as of
the date of this Joint Proxy Statement/Prospectus to the effect that, based on
the factors stated therein, the consideration to be received by THB's
stockholders pursuant to the Merger Agreement is fair to the stockholders of THB
from a financial point of view. A copy of the fairness opinion of Webb is
attached hereto as Appendix C and should be read in its entirety.

Recommendation of the Boards of Directors of PennFirst and THB

      The Boards of Directors of PennFirst and THB have determined that the
Merger is in the best interests of their respective stockholders and,
accordingly, have unanimously approved the Merger. THE BOARDS OF DIRECTORS OF
PENNFIRST AND THB UNANIMOUSLY RECOMMEND THAT THEIR RESPECTIVE STOCKHOLDERS VOTE
FOR THE MERGER AGREEMENT. SEE "THE MERGER - BACKGROUND OF AND REASONS FOR THE
MERGER."

Option Agreement

      In fulfillment of a condition to PennFirst's obligation under the Merger
Agreement, PennFirst and THB entered into an Option Agreement, a copy of which
is attached to this Joint Proxy Statement/Prospectus as Appendix B. Pursuant to
the Option Agreement, THB granted to PennFirst an option (the "PennFirst
Option"), exercisable in whole or in part only under certain circumstances, to
purchase up to 213,000 authorized but unissued shares of THB Common Stock at a
price of $15.75 per share. The per share exercise price of the PennFirst Option
was determined by arm's length negotiations and was based on the historical
market price of the THB Common Stock prior to the announcement of the Merger.
The purpose of the PennFirst Option is to increase the likelihood that the
Merger will occur by making it more difficult and expensive for another party to
acquire THB. See "The Merger - Option Agreement."

Stockholders Agreement

      In conjunction with the Merger Agreement and the Option Agreement,
PennFirst has entered into a Stockholders Agreement, dated as of September 16,
1996, with each of the directors and certain officers of THB ("Stockholders
Agreement"). Pursuant to such Stockholders Agreement, each such director and
officer of THB has agreed, among other things, not to sell, pledge, transfer or
otherwise dispose of his or her shares of THB Common Stock and to vote such
shares of THB Common Stock in favor of the Merger Agreement. See "The Merger -
Stockholders Agreement."


                                      -12-
<PAGE>

Effective Time of the Merger; Termination of the Merger Agreement

      The Merger shall become effective at the time and on the date specified in
the Articles of Merger to be filed with the Secretary of State of the
Commonwealth of Pennsylvania (the "Effective Time"). Such filing will occur only
after the receipt of all requisite regulatory approvals, approval of the Merger
Agreement by the requisite vote of PennFirst's and THB's respective
stockholders, the expiration of all applicable regulatory waiting periods and
the satisfaction or waiver of all other conditions to the Merger. See "The
Merger - Effective Time of the Merger; Termination and Amendment."

      The Merger Agreement may be terminated by mutual consent of PennFirst and
THB and by PennFirst or THB if either (i) the Merger has not been consummated on
or prior to September 30, 1997; (ii) the stockholders of either PennFirst or THB
do not approve the Merger Agreement; (iii) any of the required regulatory
applications are denied or are approved contingent upon the satisfaction of any
condition or requirement which materially impairs the value of THB to PennFirst;
or (iv) there is a material breach of any representation, warranty, covenant or
undertaking by the other party which is not cured within the specified time
period. See "The Merger - Effective Time of the Merger; Termination and
Amendment."

Conditions to the Merger

      Consummation of the Merger is subject to various conditions, including,
without limitation, obtaining the requisite approval of the Merger Agreement by
the stockholders of PennFirst and THB; receipt of all necessary regulatory
approvals pertaining to the Merger, including those from the Office of Thrift
Supervision ("OTS"); and certain other closing conditions. A holding company
application has been filed by PennFirst with the OTS with respect to the Merger.
There can be no assurance that all requisite regulatory approvals will be
obtained by PennFirst promptly or at all. See "The Merger - Conditions to the
Merger" and "The Merger - Regulatory Approvals." Substantially all of the
conditions to consummation of the Merger (except for required stockholder and
regulatory approvals) may be waived at any time by the party for whose benefit
they were created, and the Merger Agreement may be amended at any time by
written agreement of the parties, except that no waiver or amendment occurring
after approval of the Merger Agreement by PennFirst's and THB's respective
stockholders shall modify either the amount or the form of the Merger
Consideration.

Dissenters' Rights

      Holders of shares of THB Common Stock who object to the Merger and comply
with the prescribed statutory procedures are entitled to have the fair value of
their shares determined in accordance with the Pennsylvania Business Corporation
Law ("BCL") and paid to them in cash in lieu of the shares of PennFirst Common
Stock and/or cash they would otherwise be entitled to receive in the Merger. A
copy of the pertinent statutory provisions of the BCL is attached to this Joint
Proxy Statement/Prospectus as Appendix D.


                                      -13-
<PAGE>

Failure to follow such provisions precisely may result in a loss of dissenters'
rights. See "The Merger - Dissenters' Rights."

Certain Federal Income Tax Consequences

      Consummation of the Merger is conditioned upon an opinion of counsel
delivered to both PennFirst and THB to the effect that the Merger will
constitute a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code") and that no taxable gain will be
recognized by PennFirst or THB in connection with the Merger. The opinion of
counsel is summarized under "The Merger - Certain Federal Income Tax
Consequences" and is filed as an exhibit to the Registration Statement of which
this Joint Proxy Statement/Prospectus is a part. No gain or loss will be
recognized by the stockholders of THB upon the exchange of their shares of THB
Common Stock for shares of PennFirst Common Stock, except for cash received in
lieu of fractional shares. A THB stockholder who exchanges shares of THB Common
Stock for cash, either as part of the Merger Consideration or through the
exercise of dissenters' rights, will recognize gain or loss, but not in excess
of the amount of cash received. See "The Merger - Certain Federal Income Tax
Consequences."

Accounting Treatment of the Merger

      It is a condition to consummation of the Merger that the Merger be
accounted for as a purchase for accounting purposes. See "The Merger -
Conditions to the Merger " and "The Merger - Accounting Treatment of the
Merger."

Interests of Certain Persons in the Merger

      The Merger Agreement contains provisions which require PennFirst to
increase the size of its board and the size of ESBB's board by one member and
elect one person (to be designated by PennFirst) as a director for a term of not
less than three years. PennFirst has agreed to operate Troy Hill as a separate
subsidiary for a period of not less than one year following the Effective Time.
Upon consummation of the Merger, Charlotte A. Zuschlag, President and Chief
Executive Officer of PennFirst and ESBB, will become President of Troy Hill. In
the event Troy Hill is thereafter merged with or consolidated into ESBB, (i) the
current Chairman of the Board of Troy Hill will be appointed to a newly created

Unaudited Pro Forma Condensed Combined Summary Financial Information

      The unaudited pro forma condensed combined summary financial information
set forth below gives effect to the Merger under the purchase accounting method.
The pro forma condensed combined summary statements of income treat the Merger
as if it had been consummated at the beginning of the respective periods, and
the pro forma condensed combined summary balance sheet treats the Merger as if
it had been consummated on September 30, 1996. The pro forma combined per share
data gives effect to the assumed issuance of 985,687 shares of PennFirst Common
Stock based on the Exchange Ratio. For a description of the bases for the pro
forma adjustments, including the basis for the number of shares of PennFirst
Common Stock which are assumed to be issued, in the Merger, see "Unaudited Pro
Forma Condensed Combined Financial Information."

      This pro forma financial information is presented for illustrative
purposes only and is not necessarily indicative of the operating results or
financial position that would have occurred if the Merger had been consummated
at the dates assumed for purposes hereof, nor is it necessarily indicative of
future operating results or financial position. See "Unaudited Pro Forma
Condensed Combined Financial Information."

- ----------
(1) In March 1994, PennFirst completed its acquisition of ESB Bancorp, Inc. As
    a result of the merger, PennFirst acquired $147.2 million in assets,
    including total loans of $65.0 million, and total liabilities of $121.3
    million, including $114.2 million in deposits.

(2) Includes $2.2 million in a one-time SAIF special assessment.

(3) The earnings per share have been retroactively adjusted for the
    six-for-five stock splits paid on January 25, 1992, July 25, 1992, January
    25, 1993, June 7, 1993, January 25, 1994 and January 25, 1995.

(4) With the exception of end of period ratios, all ratios are based on
    average monthly balances during the respective periods and are annualized
    where appropriate.

(5) Exclusive of the $2.2 million one-time SAIF special assessment,
    PennFirst's return on assets and return on equity would have been 0.62%
    and 8.11%, respectively, for the nine months ended September 30, 1996.

(6) The ratio is calculated by dividing noninterest operating expenses by
    total recurring operating revenues (securities and other asset sales
    excluded from revenue), adjusted by removing non-cash charges such as
    intangible amortization and foreclosed real estate charges. During the
    nine months ended September 30, 1996, the ratio excludes the $2.2 million
    one-time SAIF special assessment.

    and Supervision of THB - Troy Hill - Insurance of Accounts."

(2) Earnings per share have been stated only for periods subsequent to June
    30, 1994 because of Troy Hill's conversion to stock form on June 24, 1994.

(3) With the exception of end of period ratios, all ratios are based on
    month-end or quarter-end balances during the periods and are annualized
    where appropriate. Management does not believe that the use of month-end
    or quarter-end balances instead of daily average balances has caused any
    material differences in the information presented.

(4) Exclusive of the $326,000 one-time SAIF special assessment, THB's return
    on assets and return on equity would have been 1.11% and 5.84%,
    respectively, for the three months ended September 30, 1996. Return on
    average assets and return on average equity before cumulative effect of
    accounting change amounted to 1.54% and 11.53%, respectively, for the year
    ended June 30, 1994.

(5) Interest rate spread represents the difference between the weighted
    average yield on interest-earning assets and the weighted average rate on
    interest-bearing liabilities. Net interest margin represents net interest
    income as a percentage of average interest-earning assets.

(6) Non-performing loans consist of non-accrual loans and loans that are
    contractually past due 90 days or more but still accruing interest, and
    non-performing assets consist of non-performing loans and real estate
    acquired by foreclosure or deed-in-lieu thereof.

Special Meeting of PennFirst Stockholders

      The PennFirst Special Meeting will be held on March 18, 1997, commencing
at 10:00 a.m., Eastern Time, at the Connoquenessing Country Club located at RD
#2, Route 65, Ellwood City, Pennsylvania.

      Purpose of Meeting. The purpose of the PennFirst Special Meeting is to
consider and vote upon a proposal to approve the Merger Agreement and the
issuance of PennFirst Common Stock provided for in connection therewith and the
transaction of such other business as may properly come before the PennFirst
Special Meeting and any adjournment or adjournments thereof. It is not
anticipated that any matter other than the proposal to adopt and approve the
Merger Agreement will be brought before the PennFirst Special Meeting. If any
other matter is properly presented at the PennFirst Special Meeting for
consideration, the persons named in the enclosed form of proxy card and acting
thereunder will have discretion to vote on such matter in accordance with their
best judgment.

      Shares Outstanding and Entitled to Vote; Record Date. The close of
business on January 23, 1997 has been fixed by the Board of Directors of
PennFirst as the PennFirst Record Date for the determination of holders of
PennFirst Common Stock entitled to notice of and to vote at the PennFirst
Special Meeting and any adjournment or adjournments thereof. At the close of
business on the PennFirst Record Date, there were 3,901,780 shares of PennFirst
Common Stock outstanding and entitled to vote, held by approximately 2,500
holders of record. Each share of PennFirst Common Stock entitles the holder
thereof to one vote on each matter to be submitted to PennFirst stockholders at
the PennFirst Special Meeting.

      Vote Required. A quorum, consisting of a majority of the voting power of
the issued and outstanding stock of PennFirst entitled to vote at the PennFirst
Special Meeting, must be present in person or by proxy before any action may be
taken at the PennFirst Special Meeting. Under the BCL, the affirmative vote of a
majority of the votes cast by all


                                      -24-
<PAGE>

stockholders of PennFirst entitled to vote thereon is required to approve the
Merger Agreement. The votes may be made in person or by proxy. Shares as to
which the "ABSTAIN" box has been marked on the proxy and broker non-votes will
be counted as present for determining if a quorum is present; however, under the
BCL, an abstention or a broker non-vote is not a vote cast and thus will not
affect the number of votes required for approval. PennFirst is also seeking
stockholder approval of the Merger pursuant to the regulations of the National
Association of Securities Dealers, Inc. ("NASD") because the Merger may result
in more than a 20% increase in the number of shares outstanding of PennFirst
Common Stock. The vote required under the NASD regulations is also a majority of
the total votes cast on the proposal in person or by proxy, and thus abstentions
and broker non-votes will not affect the number of votes required for approval.

      As of the PennFirst Record Date, the directors and executive officers of
PennFirst and their affiliates in the aggregate beneficially owned and are
entitled to vote 434,676 shares or 11.14% of the outstanding shares of PennFirst
Common Stock (exclusive of shares of PennFirst Common Stock which may be
acquired upon the exercise of outstanding stock options and stock appreciation
rights).

      Voting; Solicitation and Revocation of Proxies. A proxy for use at the
PennFirst Special Meeting is being furnished to each PennFirst stockholder
together with this Joint Proxy Statement/Prospectus and is solicited by the
Board of Directors of PennFirst. Any PennFirst stockholder executing a proxy may
revoke it at any time before it is voted by filing with the Secretary of
PennFirst, at the address of PennFirst set forth on the Notice of Special
Meeting of Stockholders, written notice of such revocation; by executing a
later-dated proxy; or by attending the PennFirst Special Meeting and giving
notice of such revocation in person. Attendance at the PennFirst Special Meeting
will not, in and of itself, constitute revocation of a proxy. Each proxy
returned to PennFirst (and not revoked) will be voted in accordance with the
instructions indicated thereon. IF NO INSTRUCTIONS ARE INDICATED, THE PROXY WILL
BE VOTED FOR APPROVAL OF THE MERGER AGREEMENT, WHICH INVOLVES THE ISSUANCE OF
PENNFIRST COMMON STOCK IN CONNECTION WITH THE MERGER.

Special Meeting of THB Stockholders

      The THB Special Meeting will be held on March 17, 1997, commencing at
10:00 a.m., Eastern Time, at the Holiday Inn located at 4859 McKnight Road,
Pittsburgh, Pennsylvania.

      Purpose of Meeting. The purpose of the THB Special Meeting is to consider
and vote upon a proposal to approve the Merger Agreement and the transaction of
such other business as may properly come before the THB Special Meeting and any
adjournment or adjournments thereof. It is not anticipated that any matter other
than the proposal to adopt and approve the Merger Agreement will be brought
before the THB Special Meeting. If any other matter is properly presented at the
THB Special Meeting for consideration, the persons named in the enclosed form of
proxy card and acting thereunder will have discretion to vote on such matter in
accordance with their best judgment.

entitled to notice of and to vote at the THB Special Meeting and any adjournment
or adjournments thereof. At the close of business on the THB Record Date, there

which the "ABSTAIN" box has been marked on the proxy and broker non-votes will

                                   THE MERGER

      The following description of the material terms of the Merger does not
purport to be complete and is qualified in its entirety by reference to the
Merger Agreement, a copy of which is attached to this Joint Proxy
Statement/Prospectus as Appendix A. All stockholders of PennFirst and THB are
urged to read such document carefully.

General

      The Boards of Directors of PennFirst and THB have determined that the
acquisition of THB by PennFirst is desirable and in the best interests of
PennFirst's and THB's respective stockholders and have unanimously approved the
Merger. The Merger will be accomplished through the Merger of THB with and into
PennFirst pursuant to the Merger Agreement, with PennFirst being the surviving
corporation. THE BOARDS OF DIRECTORS OF PENNFIRST AND THB UNANIMOUSLY RECOMMEND
A VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT. Upon consummation of the
Merger, each share of THB Common Stock outstanding at the Effective Time will be
converted into and represent the right to receive shares of PennFirst Common
Stock, cash or a combination of both, as described under "The Merger - The
Merger Consideration."

Background of and Reasons for the Merger

      Background of the Merger. In connection with its strategic planning
process, THB reviews its strategic business alternatives, devoting particular
attention to the continuing consolidation and increasing competition within the
banking and financial services industries in the Pittsburgh market area. The
Pittsburgh market is home to several large regional commercial banking entities
which have substantially greater financial and marketing


                                      -27-
<PAGE>

resources available to them as well as a significant number of commercial banks
and savings institutions which are reasonably comparable to THB and PennFirst in
size and resources. In recent years, competition within the local banking and
financial services industries has intensified, especially for smaller
institutions such as THB, leading to THB's exploration of a possible business
combination with PennFirst.

      In early June 1996, a representative of THB approached executive
management of PennFirst, indicating that THB was interested in meeting with
representatives of PennFirst to discuss a possible transaction between the two
companies. As a result of this indication of interest, Ellry N. Davis, President
and Chief Executive Officer of THB, and Charlotte A. Zuschlag, President and
Chief Executive Officer of PennFirst, met on June 6, 1996 in order to discuss
the respective companies, the competitive challenges faced by each,
consolidation within the banking industry generally and the possible strategic
benefits of a business combination between PennFirst and THB.

      On June 14, 1996, THB received a letter from PennFirst, dated June 13,
1996, which indicated PennFirst's interest in continuing to discuss a possible
transaction with THB, proposed in general terms the structure of a possible
transaction and outlined certain potential plans for integrating the combined
companies. The June 13th letter summarized the informal discussions that Ms.
Zuschlag and Mr. Davis had held to date, but did not include any formal offer.
On June 14, 1996, Ms. Zuschlag met with the full Board of Directors of THB in
order to familiarize them with PennFirst, its business strategies and long range
goals and to discuss the June 13th letter. Additional telephone conversations
and meetings among the parties continued over the next several weeks, during
which the parties continued to discuss the possible strategic benefits of a
business combination, as well as certain considerations related to the proposed
management and staffing of the combined company. On August 23, 1996, PennFirst
and THB entered into a mutual confidentiality agreement and, between September
4, 1996 and September 15, 1996, PennFirst and THB conducted reciprocal due
diligence analysis. On September 9, 1996, THB engaged Webb as its financial
advisor.

      On September 16, 1996, at a meeting of the Board of Directors of THB, the
THB Board discussed the reasons for, and the potential benefits of, the Merger;
THB's legal counsel reviewed the terms of the Merger Agreement, the Option
Agreement and the Stockholders Agreement and the transactions contemplated
thereby; and THB's financial advisor made a presentation regarding the financial
terms of the Merger Agreement and delivered its opinion that the Merger
Consideration was fair, from a financial point of view, to holders of THB Common
Stock. After a thorough discussion and consideration of the factors discussed
below under "The Merger - Background of and Reasons for the Merger Reasons for
the Merger," the Board of Directors of THB unanimously approved the Merger
Agreement and the transactions contemplated thereby and authorized the execution
of the Merger Agreement and the Option Agreement.

      On September 16, 1996, at a meeting of the Board of Directors of
PennFirst, Ms. Zuschlag reviewed with the PennFirst Board the reasons for, and
the potential benefits of the Merger; and PennFirst's legal counsel reviewed the
terms of the Merger Agreement, the Option Agreement and the Stockholders
Agreement and the transactions contemplated thereby. After a thorough discussion
and consideration of the factors discussed below under "The Merger - Background
of and Reasons for the Merger - Reasons for the Merger," the Board of Directors
of PennFirst unanimously approved the Merger Agreement and the transactions
contemplated thereby and authorized the execution of the Merger Agreement, the
Option Agreement and the Stockholders Agreement. The Merger Agreement, the
Option Agreement and the Stockholders Agreement were entered into on September
16, 1996.

      Reasons for the Merger. The terms of the Merger Agreement, including the
Merger Consideration to be paid to THB's stockholders, were the result of
arm's-length negotiations between the representatives of PennFirst and THB.
Among the factors considered by the Boards of Directors of PennFirst or THB, as
appropriate, in deciding to approve and recommend the terms of the Merger were
(i) the Merger Consideration to be paid to THB's stockholders in relation to the
market value, book value, earnings per share and dividend rates of the PennFirst
Common Stock and the THB Common Stock, (ii) the ability to expand PennFirst's
presence in Allegheny County, Pennsylvania, (iii) information concerning the
financial condition, results of operations, capital levels, asset quality and
prospects of PennFirst and THB, (iv) the short-term and long-term impact the
Merger will have on PennFirst's consolidated results of operations, including
anticipated cost savings resulting from consolidations in certain areas and
expanded consumer lending and retail banking products and services, (v) the
general structure of the transaction and the compatibility of management and
business philosophy, (vi) the improvement of the franchise value of PennFirst to
its stockholders as a result of the enhanced network and products and services,
(vii) the likelihood of receiving the requisite regulatory approvals in a timely
manner, (viii) the tax-free nature of the stock portion of the Merger
Consideration to the stockholders of THB, (ix) the ability of the combined
enterprise to compete in relevant banking and non-banking markets, (x) industry
and economic conditions, (xi) the impact of the Merger on the depositors,
employees, customers and communities served by PennFirst and THB through
expanded consumer lending and retail banking products and services, and (xii)
the opinion of THB's financial advisor as to the fairness of the Merger
Consideration from a financial point of view to the holders of the THB Common
Stock. In making their determination, the Boards of Directors of PennFirst and
THB did not ascribe relative weights to the factors which they considered.

      The Boards of Directors of PennFirst and THB believe that the Merger is in
the best interest of their respective organizations and their respective
stockholders. THE PENNFIRST AND THB DIRECTORS UNANIMOUSLY RECOMMEND THAT
PENNFIRST AND THB STOCKHOLDERS, RESPECTIVELY, VOTE FOR THE APPROVAL OF THE
MERGER.

Opinion of THB's Financial Advisor

      On September 9, 1996, the Board of Directors of THB retained Webb as its
financial advisor to issue an opinion as to the fairness ("Fairness Opinion"),
from a financial point of view, to the shareholders of THB with respect to the
proposed merger of THB with PennFirst. Webb, as part of its investment banking
business, is regularly engaged in the evaluation of businesses and securities in
connection with mergers and acquisitions, negotiated underwritings, and
distributions of listed and unlisted securities. Webb is familiar with the
market for common stocks of publicly traded banks, thrifts and bank and thrift
holding companies. The THB Board of Directors selected Webb on the basis of the
firm's reputation and its experience and expertise in transactions similar to
the Merger and its prior work for and relationship with THB in connection with
THB's public offering of common stock.

      Pursuant to its engagement, Webb was asked to render an opinion as to the
fairness, from a financial point of view, of the Merger Consideration to
shareholders of THB. Webb delivered its opinion to the THB Board of Directors
dated as of September 16, 1996, that the Merger Consideration was fair, from a
financial point of view, to the shareholders of THB. Such Opinion was updated as
of the date of this Joint Proxy Statement/Prospectus. No limitations were
imposed by the THB Board of Directors upon Webb with respect to the
investigations made or procedures followed by it in rendering its opinion. Webb
has consented to the inclusion herein of the summary of its opinion to the THB
Board of Directors and to the reference to the entire opinion attached hereto as
Appendix C.

      The full text of the opinion of Webb, which is attached as Appendix C to
this Joint Proxy Statement/Prospectus, sets forth certain assumptions made,
matters considered and limitations on the review undertaken by Webb, and should
be read in its entirety. The summary of the opinion of Webb set forth in this
Joint Proxy Statement/Prospectus is qualified in its entirety by reference to
the opinion. Such opinion does not constitute a recommendation by Webb to any
THB shareholder as to how such shareholder should vote with respect to the
Merger.

      In rendering its opinion, Webb (i) reviewed drafts of the Merger
Agreement; (ii) reviewed THB's Annual Reports, Proxy Statements and Form 10-K's
for the years ended June 30, 1995, 1994, and a draft of June 30, 1996 financial
statements; (iii) reviewed PennFirst's Annual Reports, Proxy Statements and Form
10-K's for the years ended December 31, 1995, 1994 and 1993, subsequent 10-Q's,
and certain other internal financial analysis considered relevant; (iv)
discussed with senior management and the boards of directors of THB and its
wholly-owned subsidiary, Troy Hill, the current position and prospective outlook
for THB; (v) discussed with senior management PennFirst's operations, financial
performance and future plans and prospects; (vi) considered historical
quotations, levels of activity and prices of recorded transactions in THB's and
PennFirst's Common Stocks; (vii) reviewed financial and stock market data of
other thrifts in a comparable asset range to THB; (viii) reviewed financial and
stock market data of other thrifts in a


                                      -30-
<PAGE>

comparable asset range to PennFirst; (ix) reviewed certain recent business
combinations with thrifts as the acquired company, which Webb deemed comparable
in whole or in part; (x) performed other analyses which Webb considered
appropriate.

      In rendering it opinion, Webb assumed and relied upon the accuracy and
completeness of the financial information provided to it by THB and PennFirst.
In its review, with the consent of the THB Board of Directors, Webb did not
undertake any independent verification of the information provided to it, nor
did it make any independent appraisal or evaluation of the assets or liabilities
of THB or PennFirst, and potential or contingent liabilities of THB or
PennFirst.

      Analysis of Comparable Publicly Traded Companies. Webb compared selected
publicly available financial information of a comparable peer group of THB
consisting of assets between $50-$200 million and located in the Mid-Atlantic
Region. The peer group consisted of eleven institutions located in the states of
Pennsylvania, New York, New Jersey, and Maryland. Financial data and comparisons
included, but were not limited to, (i) stock price to tangible book value (THB
was 81% of book value compared to the peer group median of 81%); (ii) stock
price to last twelve months ("LTM") earnings (THB was 12.6x LTM earnings
compared to the peer group median of 15.2x); (iii) return on average assets
(THB, based on LTM earnings, was 1.38% compared to the peer group median of
 .80%); (iv) return on average equity (THB, based on LTM earnings, was 6.1%
compared to the peer group median of 5.2%); and (v) tangible equity as a
percentage of total assets (THB reported 22.2% compared to the peer group median
of 15.7%).

      Webb also analyzed the performance and financial condition of PennFirst
relative to a peer group of thrifts with assets between $500 million and $750
million and located in the Mid-Atlantic region. The peer group consisted of
thirteen financial institutions located in Pennsylvania, New York, Maryland, and
New Jersey. Financial data and comparisons included but were not limited to, (i)
stock price to tangible book value (PennFirst's 117% of tangible book value
compared to the peer group median of 118%); (ii) stock price to LTM earnings
(PennFirst's 12.9x LTM earnings compared to the peer group median of 12.7x);
(iii) return on average assets (PennFirst's, based on LTM earnings, was .62%
compared to the peer group median of .91%); (iv) return on average equity
(PennFirst, based on LTM earnings, reported 7.7% compared to the peer group
median of 7.7%); and (v) tangible equity as a percentage of total assets
(PennFirst reported 6.3% compared to the peer group median of 8.2%).

      Analysis of Recent Comparable Acquisition Transactions. In preparing its
opinion, Webb analyzed certain comparable merger and acquisition transactions of
both pending and completed thrift deals, comparing the acquisition price
relative to stated book value, tangible book value, LTM earnings, total assets,
total deposits, and premium to core deposits. The analysis included a comparison
of the average and median of the above ratios for completed and pending
acquisitions, based on the following three comparable groups: (i) all thrift
acquisitions since June 30, 1995 with the target thrift having assets between
$25 million and


                                      -31-
<PAGE>

$250 million ("Recent Transactions"); (ii) all thrift acquisitions since June
30, 1995 with the selling thrift having a return on average equity between 4.5%
and 9.0% ("Comparable Earnings Ratio"); and (iii) all acquisitions since June
30, 1995 with the selling thrift having 15% or more equity to total assets
("Comparable Equity Ratio").

      The information in the following table summarizes the material information
analyzed by Webb with respect to the Merger. The summary does not purport to be
a complete description of the analyses performed by Webb and should not be
construed independently of the other information considered by Webb in rendering
its opinion. Selecting portions of Webb's analysis or isolating certain aspects
of the comparable transactions without considering all analysis and factors,
could create an incomplete or potentially misleading view of the evaluation
process.

      In preparing its analysis, Webb made numerous assumptions with respect to
industry performance, business and economic conditions and other matters, many
of which are beyond the control of Webb and THB. The analyses performed by Webb
are not necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses and do not
purport to be appraisals or reflect the prices at which a business may be sold.

      Webb will receive a fee of $80,000 for services rendered in connection
with advising, issuing a fairness opinion and coordinating the due diligence
sessions of PennFirst with respect to the Merger. As of the date of the Joint
Proxy Statement/Prospectus, Webb has received $30,000 of such fee; the remainder
of the fee is due upon approval by THB's shareholders of the Merger. Webb was
paid a fee in connection with the services it performed in connection with THB's
stock offering in 1994.

The Merger Consideration

      The Merger Agreement provides that at the Effective Time of the Merger,
each share of THB Common Stock outstanding immediately prior to consummation of
the Merger (other than shares as to which dissenters' rights have been asserted
and duly perfected in accordance with Pennsylvania law and shares held by
PennFirst, THB or any of their respective subsidiaries) shall be converted into
and represent the right to receive either (i) $21.15 in cash ("Per Share Cash
Consideration") or (ii) a number of shares of PennFirst Common Stock with a
value equal to $21.15 ("Per Share Stock Consideration"), as determined by the
Exchange Ratio and based on the Average Share Price of PennFirst Common Stock
over the 20 trading day period ("Pricing Period") ending on the date PennFirst
and THB receive all requisite regulatory approvals and satisfy all applicable
waiting periods related to the Merger. The Exchange Ratio in the Merger
Agreement provides that the number of shares of PennFirst Common Stock
comprising the Per Share Stock Consideration shall be equal to the quotient
determined by dividing (x) $21.15 by (y) the Average Share Price (defined as the
average of the high bid and low asked price per share as reported by the NASDAQ
National Market) during the Pricing Period. The Merger Agreement provides that
60% of the aggregate Merger Consideration will consist of PennFirst Common Stock
and the remaining 40% shall consist of cash.

      If, between the date of this Joint Proxy Statement/Prospectus and the
Effective Time, the shares of PennFirst Common Stock are changed into a
different number or class of shares by reason of any reclassification,
recapitalization, split-up, combination, exchange of shares or readjustment, or
a stock dividend thereon is declared with a record date within said period, the
Merger Consideration as specified above shall be adjusted accordingly.

      Election and Exchange Procedures. As promptly as practicable after the
Effective Time (and in no event later than seven business days following the
Effective Time), PennFirst shall cause a to-be-designated exchange agent
("Exchange Agent") to mail to each holder of record of a certificate or
certificates which immediately prior the Effective Time


                                      -33-
<PAGE>

represented issued and outstanding shares of THB Common Stock (i) a notice and
letter of transmittal (which shall specify that delivery shall be effected and
risk of loss and title to the certificates theretofore representing shares of
THB Common Stock shall pass only upon proper delivery of such certificates to
the Exchange Agent) advising such holder of the effectiveness of the Merger and
the procedure for surrendering to the Exchange Agent such certificate or
certificates in exchange for that Merger Consideration and (ii) an election form
in such form as PennFirst and THB shall mutually agree ("Election Form"). Each
Election Form shall permit the holder (or in the case of nominee record holders,
the beneficial owner through proper instructions and documentation) (i) to elect
to receive PennFirst Common stock with respect to all such holder's THB Common
Stock (the "Stock Election Shares"), (ii) to elect to receive cash with respect
to all such holder's THB Common Stock (the "Cash Election Shares"), or (iii) to
indicate that such holder makes no such election with respect to such holder's
shares of THB Common Stock (the "No-Election Shares"). Any shares of THB Common
Stock with respect to which the holder thereof shall not, as of a
to-be-specified deadline ("Election Deadline"), have made such an election by
submission to the Exchange Agent of an effective, properly completed Election
Form shall be deemed to be No-Election Shares.

      Any election to receive PennFirst Common Stock or cash shall have been
properly made only if the Exchange Agent shall have actually received a properly
completed Election Form by the Election Deadline. An Election Form will be
properly completed only if accompanied by certificates representing all shares
of THB Common Stock covered thereby, subject to certain limited exceptions in
the case of lost or destroyed certificates. Any Election Form may be revoked or
changed by the person submitting such Election Form to the Exchange Agent by
written notice to the Exchange Agent only if such notice is actually received by
the Exchange Agent at or prior to the Election Deadline. The certificate or
certificates representing THB Common Stock relating to any revoked Election Form
shall be promptly returned without charge to the person submitting the Election
Form to the Exchange Agent. The Exchange Agent shall have reasonable discretion
to determine when any election, modification or revocation is received and
whether any such election, modification or revocation has been properly made.

      Within ten business days after the Election Deadline, the Exchange Agent
will effect the allocation among holders of THB Common Stock of rights to
receive PennFirst Common Stock or cash in accordance with the Election Form.

      If the number of Cash Election Shares times $21.15 is less than the
product of the number of shares of THB Common Stock (other than shares of THB
Common Stock owned by THB (including treasury shares) or PennFirst) outstanding
at the Effective Time times .40 times $21.15 (the "Aggregate Cash
Consideration"), then:

            (1) all Cash Election Shares will be converted into the right to
      receive cash,


                                      -34-
<PAGE>

            (2) the Exchange Agent will select first from among the holders of
      No-Election Shares and then (if necessary) will allocate among the holders
      of Stock Election Shares (by the method of allocation described below), a
      sufficient number of Stock Election Shares ("Reallocated Cash Shares")
      such that the sum of the number of Cash Election Shares plus the number of
      Reallocated Cash Shares times $21.15 equals the Aggregate Cash
      Consideration, and all Reallocated Cash Shares will be converted in the
      right to receive cash, and

            (3) the No-Election Shares and Stock Election Shares which are not
      Reallocated Cash Shares will be converted into the right to receive
      PennFirst Common Stock.

      If the number of Cash Election Shares times $21.15 is greater than the
Aggregate Cash Consideration, then:

            (1) all Stock Election Shares and No-Election Shares will be
      converted into the right to receive PennFirst Common Stock,

            (2) the Exchange Agent will allocate among the holders of Cash
      Election Shares (by the method of allocation described below), a
      sufficient number of Cash Election Shares ("Reallocated Stock Shares")
      such that the number of remaining Cash Election Shares times $21.15 equals
      the Aggregate Cash Consideration, and all Reallocated Stock Shares shall
      be converted into the right to receive PennFirst Common Stock, and

            (3) the Cash Election Shares which are not Reallocated Stock Shares
      will be converted into the right to receive cash.

      After the completion of the foregoing allocation, each holder of an
outstanding certificate or certificates which prior thereto represented shares
of THB Common Stock who surrenders such certificate or certificates to the
Exchange Agent will, upon acceptance thereof by the Exchange Agent, be entitled
to a certificate or certificates representing the number of full shares of
PennFirst Common stock or the amount of cash into which the aggregate number of
shares of THB Common stock previously represented by such certificate or
certificates surrendered shall have been converted pursuant to the Merger
Agreement and, if such holder's shares of THB Common Stock have been converted
into PennFirst Common Stock, any other distribution theretofore paid with
respect to PennFirst Common Stock issuable in the Merger, in each case without
interest. The Exchange Agent shall accept such certificates upon compliance with
such reasonable terms and conditions as the Exchange Agent may impose to effect
an orderly exchange thereof in accordance with normal exchange practices. Each
outstanding certificate which prior to the Effective Time represented THB Common
Stock and which is not surrendered to the Exchange Agent in accordance with the
procedures provided for in the Merger Agreement shall, except as otherwise
provided in the Merger Agreement, until duly surrendered to the Exchange Agent


                                      -35-
<PAGE>

be deemed to evidence ownership of the number of shares of PennFirst Common
Stock or the right to receive the amount of cash into which such THB Common
Stock shall have been converted. After the Effective Time, there shall be no
further transfer on the records of THB of certificates representing shares of
THB Common Stock and if such certificates are presented to PennFirst for
transfer, they shall be cancelled against delivery of certificates for PennFirst
Common Stock or cash as provided in the Merger Agreement. No dividends which
have been declared will be remitted to any person entitled to receive shares of
PennFirst Common Stock until such person surrenders the certificate or
certificates representing THB Common stock, at which time such dividends shall
be remitted to such person, without interest.

      No Fractional Shares of PennFirst Common Stock to be Issued. No fractional
shares of PennFirst Common Stock shall be issued in the Merger to holders of
shares of THB Common Stock. Each holder of shares of THB Common Stock who
otherwise would have been entitled to a fraction of a share of PennFirst Common
Stock shall receive in lieu thereof, at the time of surrender of the certificate
or certificates representing such holder's shares of THB Common Stock, an amount
of cash (without interest) determined by multiplying the fractional share
interest to which such holder would otherwise be entitled by $21.15.

      Treatment of Outstanding Stock Options for THB Common Stock. The Merger
Agreement provides that upon consummation of the Merger, each outstanding option
to acquire THB Common Stock ("Option"), other than the PennFirst Option, whether
or not otherwise exercisable or vested, shall become fully exercisable and
vested immediately prior to the Effective Time at which time each holder of an
Option shall receive either (x) an amount in cash in cancellation of such Option
determined by multiplying (i) the excess, if any, of $21.15 over the applicable
exercise price per share of such Option by (ii) the number of shares of THB
Common Stock subject to such Option, or (y) an option to acquire shares of
PennFirst Common stock, on the same terms and conditions as were applicable
under such Option immediately prior to the Effective Time. The number of shares
of PennFirst Common Stock which may be acquired upon exercise of any such new
option shall be equal to the product of the number of shares of THB Common Stock
subject to the original Option multiplied by the Exchange Ratio, rounded down to
the nearest whole number of shares, and the exercise price of any such new
option shall be equal to the exercise price of the original THB Option divided
by the Exchange Ratio, rounded up to the nearest cent.

Conditions to the Merger

      The Merger Agreement provides that consummation of the proposed
transaction is subject to the satisfaction of certain conditions, or the waiver
of such conditions by the party entitled to do so, at or before the Effective
Time. Each of the parties' obligations under the Merger Agreement is subject to
the following conditions, among others: (a) the receipt of all necessary
regulatory or governmental approvals and consents required to consummate the
transactions contemplated by the Merger Agreement without any term or condition


                                      -36-
<PAGE>

which would materially impair the value of THB and its subsidiaries to
PennFirst, the satisfaction of all conditions required to be satisfied prior to
the Effective Time by the terms of such approvals and consents, and the
expiration of all waiting periods with respect thereto; (b) all corporate action
(including stockholder approvals) necessary to authorize the execution and
delivery of the Merger Agreement and consummation of the transactions
contemplated thereby shall have been duly and validly taken; (c) the absence of
any order, judgment or decree that would have the effect of preventing
completion of the Merger and the absence of any pending or threatened suit,
action or other proceeding to restrain or prohibit the Merger or seeking to
obtain substantial monetary or other relief which either party determines, based
upon the advice of counsel, has a significant potential to result in the
deprivation of material benefits of the Merger; (d) the Registration Statement
shall have become effective under the Securities Act, PennFirst shall have
received all permits, authorizations or exemptions necessary under all state
securities laws to issue the PennFirst Common Stock in connection with the
Merger, and neither the Registration Statement nor any such permit,
authorization or exemption shall be subject to a stop order or threatened stop
order by the Commission or any state securities authority; and (e) PennFirst and
THB shall have received an opinion from Elias, Matz, Tiernan & Herrick L.L.P. to
the effect that, among other things, the Merger will qualify as a
"reorganization" under Section 368(a) of the Code and no taxable gain will be
recognized by PennFirst or THB (i) upon the transfer of THB's assets to
PennFirst in exchange for PennFirst Common Stock, cash and the assumption of
THB's liabilities or (ii) upon the distribution of PennFirst Common Stock and
cash to THB's stockholders. See "The Merger - Certain Federal Income Tax
Consequences."

      In addition to the foregoing conditions, PennFirst's obligations under the
Merger Agreement are conditioned upon, among others: (a) the performance in all
material respects by THB of all obligations to be performed by it and the
accuracy as of September 16, 1996 and as of the Effective Time (as though made
at and as of the Effective Time) of the representations and warranties of THB
set forth in the Merger Agreement, except as to any representation or warranty
which specifically relates to an earlier date and except as otherwise provided
in the Merger Agreement; (b) the receipt of all permits, consents, waivers,
clearances, approvals and authorizations from regulatory or governmental
authorities or third parties which are necessary in connection with the
consummation of the Merger, and none of such permits, consents, waivers,
clearances, approvals and authorizations shall contain any term or condition
which would materially impair the value of THB and its subsidiaries to
PennFirst; (c) the receipt by PennFirst of a letter from KPMG Peat Marwick LLP
to the effect that the Merger will qualify for purchase accounting treatment;
(d) the amount of THB Common Stock held by stockholders of THB who dissent from
the Merger pursuant to the applicable provisions of the BCL shall not exceed 15%
of the THB Common Stock immediately prior to the Effective Time; (e) the
execution by certain stockholders of THB of an agreement regarding compliance
with Rule 145 under the Securities Act; and (f) the receipt from THB of such
certificates of its officers or others and such other documents to evidence
fulfillment of the conditions as PennFirst may reasonably request.


                                      -37-
<PAGE>

      In addition to the conditions set forth above as applicable to both
parties, THB's obligations under the Merger Agreement are conditioned upon,
among others: (a) the performance in all material respects by PennFirst of all
obligations to be performed by it and the accuracy as of September 16, 1996 and
as of the Effective Time (as though made at and as of the Effective Time) of the
representations and warranties of PennFirst set forth in the Merger Agreement,
except as to any representation or warranty which specifically relates to an
earlier date and except as otherwise provided in the Merger Agreement; and (b)
the receipt from PennFirst of such certificates of its officers or others and
such other documents to evidence fulfillment of the conditions as THB may
reasonably request.

Regulatory Approvals

      Consummation of the Merger is subject to, among other things, prior
receipt of all requisite approvals from the OTS and any other regulatory agency
of competent jurisdiction necessary to consummate the Merger and expiration of
all regulatory waiting periods applicable to the Merger. PennFirst has applied
to the OTS pursuant to Section 10(e)(1)(A) of the HOLA to merge THB with and
into PennFirst and to acquire Troy Hill. Other applications required under state
securities laws have been filed with the appropriate regulatory authorities.

      The period for the OTS' review of any proposed acquisition, such as the
acquisition of THB, commences upon receipt by the OTS of an application deemed
sufficient by the OTS. Once an application is deemed sufficient, the OTS
generally has a 60-day period for review of the application, which may be
extended by the OTS for up to an additional 30 days.

      Generally, the OTS will approve an application unless it determines that
the financial and managerial resources and future prospects of the acquiror and
the savings association involved would be detrimental to the savings association
or to the SAIF or the Bank Insurance Fund ("BIF"), or if the acquiror fails or
refuses to furnish information requested by the OTS. The OTS will also consider
the convenience and needs of the community to be served, and it will examine the
impact of the acquisition under the relevant antitrust laws.

      The regulations provide that an acquiror must publish a notification, no
earlier than three calendar days before and no later than three calendar days
after filing an application, in the community in which the home office of the
savings association to be acquired is located. Generally, within 20 calendar
days of the date of filing (or up to 40 calendar days after such date if an
extension is requested in writing within the initial 20-day period), anyone may
file comments in favor of or in protest of the application and may also submit
such information as he or she deems relevant.

      There can be no assurance that the necessary regulatory authorities will
approve the Merger, and if the Merger is approved, there can be no assurance as
to the dates of such approvals. There can also be no assurance that any such
approval will not contain a


                                      -38-
<PAGE>

condition or requirement which would cause such approval to fail to satisfy one
of the conditions to consummation of the Merger set forth in the Merger
Agreement. There can likewise be no assurance that the Department of Justice
will not challenge the Merger, or if such a challenge is made, as to the results
thereof. In the event the Merger is not consummated on or before September 30,
1997, the Merger Agreement may be terminated by either PennFirst or THB.

Business Pending the Merger

      Under the terms of the Merger Agreement, THB has agreed not to take
certain actions, nor permit its subsidiaries to take certain actions, prior to
consummation of the Merger without the prior written consent of PennFirst,
including, among other things, the following: (1) change any provision of the
Articles of Incorporation or other governing instrument or Bylaws of it or its
subsidiaries; (2) change the number of its authorized or issued capital stock or
issue or grant any option, warrant, call, commitment, subscription, right to
purchase or agreement of any character relating to the authorized or issued
capital stock of it or its subsidiaries, except for issuance of THB Common Stock
pursuant to any outstanding Option and in compliance with the terms of the
Option Agreement; (3) declare, set aside, make or pay any dividend or other
distribution other than its regular quarterly cash dividends not in excess of
$.10 per share; (4) grant any severance or termination pay (other than pursuant
to binding contracts disclosed pursuant to the Merger Agreement) to, or enter
into or amend any employment, consulting or compensation agreement with, any of
its directors, officers or employees, or award any increase in compensation or
benefits to such individuals, except, in the case of employees, such as may be
granted in the ordinary course of business consistent with past practices and
policies; (5) subject to certain exceptions, enter into or modify any employee
benefit plan or any trust agreement related thereto with respect to any of its
directors, officers or employees or make any contributions to its Employee Stock
Ownership Plan or any other defined contribution plan or similar plan other than
in the ordinary course of business consistent with past practice; (6) sell or
dispose of any significant assets or incur any significant liabilities other
than in the ordinary course of business consistent with past practices and
policies, or acquire in any manner whatsoever (other than to realize upon
collateral for a defaulted loan) any business or entity; (7) make any capital
expenditures in excess of $25,000 in the aggregate, other than pursuant to
binding commitments existing on September 16, 1996, other than expenditures
necessary to maintain existing assets in good repair and other than as disclosed
pursuant to the Merger Agreement; (8) file any applications or make any contract
with respect to branching or site location or relocation, except as disclosed
pursuant to the Merger Agreement; (9) make any material change in its accounting
methods or practices, other than changes required by generally accepted
accounting principles, or change any of its methods of reporting income and
deductions for federal income tax purposes, except as required by changes in
laws or regulations; (10) change its lending, investment, deposit or asset and
liability management or other banking policies in any material respect except as
may be required by applicable law; (11) engage in any transaction with an
"affiliated person" or "affiliate," in each case as defined in the Merger
Agreement; (12) enter into any futures contract, option or other


                                      -39-
<PAGE>

agreement or take any other action for purposes of hedging the exposure of its
interest-earning assets and interest-bearing liabilities to changes in market
rates of interest; (13) take any action that would result in any of the
representations and warranties of THB contained in the Merger Agreement not to
be true and correct in any material respect at the Effective Time; or (14) agree
to do any of the foregoing.

      Furthermore, each party has agreed to provide the other party and its
representatives with such financial data and other information with respect to
its business and properties as such party shall from time to time reasonably
request. Each party will cause all non-public financial and business information
obtained by it from the other to be treated confidentially. If the Merger is not
consummated, each party will either return to the other all non-public financial
statements, documents and other materials previously furnished by such party or
destroy such information.

Acquisition Proposals

      Until the Effective Time of the Merger or the earlier termination of the
Merger Agreement, neither THB nor its subsidiaries shall, nor shall THB or its
subsidiaries authorize or permit any of its directors, officers or employees or
any investment banker, financial advisor, attorney, accountant or other
representative of THB or its subsidiaries to, directly or indirectly, encourage
or solicit or hold discussions or negotiations with, or provide any information
to, any person, entity or group (other than PennFirst) concerning any merger,
sale of substantial assets or liabilities not in the ordinary course of
business, sale of shares of capital stock or similar transactions involving THB
or its subsidiaries (an "Acquisition Transaction"); provided, however, that THB
may provide information in connection with an unsolicited possible Acquisition
Transaction if the Board of Directors of THB, after consulting with counsel,
determines in the exercise of its fiduciary responsibilities that such
information should be furnished. Under the Merger Agreement, THB is required to
promptly communicate to PennFirst the terms of any proposal which it may receive
in respect of any such Acquisition Transaction and to provide PennFirst with
copies of (i) any written legal advice provided to the Board of Directors of
THB, (ii) all such written inquiries or proposals and (iii) an accurate and
complete written synopsis of all such oral inquiries or proposals.

Representations and Warranties

      The Merger Agreement contains representations and warranties of PennFirst
and THB which are customary in transactions of this type, including, but not
limited to, representations and warranties concerning: (a) the organization and
capitalization of PennFirst and its subsidiaries and THB and its subsidiaries;
(b) the due authorization, execution, delivery and enforceability of the Merger
Agreement; (c) consents or approvals required, and the lack of conflicts or
violations under applicable articles of incorporation, bylaws, instruments and
laws, with respect to the transactions contemplated by the Merger Agreement; (d)
the documents to be filed by PennFirst and THB with the Commission and


                                      -40-
<PAGE>

other regulatory agencies; (e) the conduct of business in the ordinary course
and absence of certain changes; (f) financial statements; (g) compliance with
laws; and (h) the allowance for loan losses and real estate owned.

Effective Time of the Merger; Termination and Amendment

      The Effective Time of the Merger shall be the date specified in the
Articles of Merger to be filed with the Secretary of State of the Commonwealth
of Pennsylvania, unless a later date and time is specified as the effective time
in such Articles of Merger. Such filing will occur only after the receipt of all
requisite regulatory approvals, approval of the Merger Agreement by the
requisite vote of PennFirst's and THB's stockholders and the satisfaction or
waiver of all other conditions to the Merger.

      A closing (the "Closing") shall take place immediately prior to the
Effective Time at 10:00 a.m. on the fifth business day following the receipt of
all necessary regulatory or governmental approvals and consents and the
expiration of all statutory waiting periods in respect thereof and the
satisfaction or waiver (to the extent permitted) of all the conditions to
consummation of the Merger, or on such later date as the parties may mutually
agree upon.

      The Merger Agreement may be terminated, either before or after approval by
the stockholders of PennFirst and THB, as follows: (a) at any time on or prior
to the Effective Time by the mutual consent of the parties; (b) by PennFirst or
THB (i) if the Effective Time shall not have occurred on or prior to September
30, 1997 or (ii) if a vote of the stockholders of PennFirst or THB is taken and
either of such stockholders fails to approve the Merger Agreement, unless in
each case the failure of such occurrence shall be due to the failure of the
party seeking to terminate the Merger Agreement to perform or observe its
agreements set forth therein to be performed or observed by such party at or
before the Effective Time; (c) by PennFirst or THB upon written notice to the
other 30 or more days after the date upon which any application for a regulatory
or governmental approval necessary to consummate the Merger and the other
transactions contemplated thereby shall have been denied or withdrawn at the
request or recommendation of the applicable regulatory agency or governmental
authority, unless within such 30-day period a petition for rehearing or an
amended application is filed or noticed, or 30 or more days after any petition
for rehearing or amended application is denied; (d) by PennFirst in writing if
THB has, or by THB in writing if PennFirst has, breached (i) any covenant or
undertaking contained in the Merger Agreement, or (ii) any representation or
warranty contained therein, which breach would have a material adverse effect on
the business, operations, assets or financial condition of THB and its
subsidiaries or PennFirst and its subsidiaries, as applicable, in each case
taken as a whole, or upon the consummation of the transactions contemplated
thereby, in any case if such breach has not been cured by the earlier of 30 days
after the date on which written notice of such breach is given to the party
committing such breach or the Effective Time; provided that either party may
terminate the Merger Agreement on the basis of any such material breach of any
representation or warranty


                                      -41-
<PAGE>

contained therein, notwithstanding any qualification therein relating to the
knowledge of the other party; and (e) by PennFirst or THB in writing, if any of
the applications for prior regulatory approval referred to in the Merger
Agreement are denied or are approved contingent upon the satisfaction of any
condition or requirement which, in the reasonable opinion of the Board of
Directors of PennFirst, would materially impair the value of THB and its
subsidiaries to PennFirst, and the time period for appeals and requests for
reconsideration has run.

      To the extent permitted under applicable law, at any time prior to the
consummation of the Merger, whether before or after approval thereof by the
stockholders of PennFirst and/or THB, the parties may by written agreement (a)
amend the Merger Agreement, (b) extend the time for the performance of any of
the obligations or other acts of the other parties thereto, (c) waive any
inaccuracies in the representations and warranties contained therein or in any
document delivered pursuant thereto, or (d) waive compliance with any of the
agreements or conditions contained therein. However, after any approval of the
Merger by the stockholders of PennFirst and/or THB, there may not be, without
further approval of such stockholders, any amendment or waiver of the Merger
Agreement which modifies either the amount or the form of the Merger
Consideration to be delivered to the stockholders of THB.

Interests of Certain Persons in the Merger

      In considering the recommendation of the THB Board of Directors,
stockholders should be aware that members of THB's management and the THB Board
of Directors have interests in the Merger that are in addition to the interests
of stockholders generally. The THB Board of Directors was aware of these
interests and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.

      Operations of Troy Hill. It is the intention of PennFirst to maintain Troy
Hill as a separate subsidiary of PennFirst for a period of not less than one
year from the Effective Time. During the period that Troy Hill is maintained as
a separate subsidiary of PennFirst, Charlotte A. Zuschlag will serve as
President and Chief Executive Officer of Troy Hill. Ms. Zuschlag will not
receive any additional compensation for serving as President of Troy Hill.
Following such one-year period, PennFirst may, in its sole discretion, determine
to merge or consolidate Troy Hill with ESBB.

      Boards of Directors of PennFirst and ESBB. Pursuant to the Merger
Agreement and effective as of the Effective Time, the number of directors of
both PennFirst and ESBB shall be increased by one and PennFirst and ESBB shall
each nominate and elect one current director of THB (to be designated by
PennFirst) as a director for a term of not less than three years. Furthermore,
in the event PennFirst determines to merge or consolidate Troy Hill and ESBB, an
additional two of the current directors of Troy Hill shall be elected to the
Board of Directors of ESBB for a term of not less than three years, and the
current Chairman of the Board of Troy Hill will be appointed to a newly created
Troy Hill Advisory


                                      -42-
<PAGE>

Board for a period of not less than one year and shall be compensated for his
services in an amount of not less than $1,300 per month.

      Board of Directors of Troy Hill. Pursuant to the Merger Agreement and
effective as of the Effective Time, the number of directors of Troy Hill shall
be increased by at least one, and the resulting vacancy shall be filled by the
election of the President and Chief Executive Officer of PennFirst, Charlotte A.
Zuschlag. Ms. Zuschlag will receive no additional compensation for serving as a
director of Troy Hill.

      Employment of Troy Hill Personnel. PennFirst has agreed to continue the
employment of all personnel of Troy Hill and its subsidiaries (other than Mr.
Davis who will retire as of the Effective Time) as of the Effective Time, except
in the event of good cause for termination, for a period of not less than twelve
months subsequent to the Effective Time.

      Transferred Employees. All employees of Troy Hill or its subsidiaries
immediately prior to the Effective Time who are employed by PennFirst, ESBB or
Troy Hill immediately following the Effective Time ("Transferred Employees")
will be covered by PennFirst's, ESBB's or Troy Hill's employee benefit plans on
substantially the same basis as any employee of PennFirst, ESBB or Troy Hill in
a comparable position. Notwithstanding the foregoing, PennFirst may determine to
continue any of the Troy Hill benefit plans for Transferred Employees in lieu of
offering participation in PennFirst's benefit plans providing similar benefits
(e.g., medical and hospitalization benefits), to terminate any of the Troy Hill
benefit plans, or to merge any such benefit plans with PennFirst's benefit
plans, provided the result is the provision of the benefits to Transferred
Employees that are substantially similar to the benefits provides to PennFirst's
employees generally. Except as specially provided in the Merger Agreement and as
otherwise prohibited by law, Transferred Employees' service with Troy Hill shall
be recognized as service with PennFirst for purposes of eligibility to
participate and vesting, if applicable (but not for purposes of benefit accrual)
under PennFirst's benefit plans, subject to applicable break-in-service rules.

      Upon consummation of the Merger, Ellry N. Davis, the current President and
Chief Executive Officer of THB and Troy Hill, will retire as both an officer and
director of THB and Troy Hill. It is expected that PennFirst will enter into a
two-year agreement ("Consulting Agreement") with Mr. Davis pursuant to which Mr.
Davis will provide certain consulting services to PennFirst subsequent to the
Merger. In return for his services under the Consulting Agreement, PennFirst has
agreed to pay Mr. Davis a fee of $71,000 during the first year and a fee of
$48,000 during the second year and to continue Mr. Davis' medical insurance
coverage during the term of the Consulting Agreement (with the costs of such
medical coverage being deducted from the fees being paid to Mr. Davis).

      Health Plans. PennFirst has agreed that any pre-existing condition,
limitation or exclusion in its medical, long-term disability and life insurance
plans shall not apply to Transferred Employees or their covered dependents who
are covered under a medical or hospitalization indemnity plan maintained by Troy
Hill on the Effective Time and who then


                                      -43-
<PAGE>

change coverage to PennFirst's medical or hospitalization indemnity health plan
at the time such Transferred Employees are first given the option to enroll.

      THB ESOP. On or after the Effective Time, the THB employee stock ownership
plan (the "THB ESOP") may, at PennFirst's discretion, be combined with the
PennFirst employee stock ownership plan (the "PennFirst ESOP"). However, prior
to any such combination of the THB ESOP and the PennFirst ESOP, the parties have
agreed to take all necessary action in order to amend the THB ESOP in order to
ensure that any such combination does not accelerate (other than as required by
law or regulation) or materially increase the benefits available to any
participant in the THB ESOP. Notwithstanding anything in the Merger Agreement to
the contrary, the parties hereto will take all necessary action to amend the THB
ESOP in order to provide that the Merger will not accelerate (other than as
required by law or regulation) or materially increase the benefits available to
any participant in the THB ESOP.

      Other than as set forth above, no director or executive officer of THB or
PennFirst has any direct or indirect material interest in the Merger, except in
the case of THB insofar as ownership of THB Common Stock and existing options
might be deemed such an interest.

Resale Considerations With Respect to the PennFirst Common Stock

      The shares of PennFirst Common Stock that will be issued if the Merger is
consummated have been registered under the Securities Act and listed on the
NASDAQ National Market and will be freely transferable, except for shares of
PennFirst Common Stock received by persons, including directors and executive
officers of THB, who may be deemed to be "affiliates" of THB under Rule 145
promulgated under the Securities Act. Affiliates may not sell their shares of
PennFirst Common Stock acquired pursuant to the Merger, except pursuant to an
effective registration statement under the Securities Act covering such shares
of PennFirst Common Stock or in compliance with Rule 145 or another applicable
exemption from the registration requirements of the Securities Act. Persons who
may be deemed to be affiliates of THB generally include individuals or entities
that control, are controlled by, or are under common control with, THB and may
include certain officers and directors of THB as well as any stockholders who
own more than 10% of the THB Common Stock.

Certain Federal Income Tax Consequences

      Elias, Matz, Tiernan & Herrick L.L.P., Washington, D. C., special counsel
to PennFirst, has rendered an opinion to PennFirst and THB as to the principal
federal income tax consequences expected to result from the Merger. Such opinion
is included as an exhibit to the Registration Statement. Neither the opinion nor
this summary addresses any tax considerations under foreign, state or local
laws, or the tax considerations to certain stockholders in light of their
particular circumstances, including persons who are not United States citizens,
or who are resident aliens, life insurance companies, dealers in securities, tax


                                      -44-
<PAGE>

exempt entities, stockholders who received their shares through the exercise of
employee stock options or through other compensation arrangements, and
stockholders who do not hold their shares as "capital assets" within the meaning
of Section 1221 of the Code.

      No rulings have been requested from the Internal Revenue Service ("IRS")
as to the federal income tax consequences of the Merger. Stockholders should be
aware that the opinion of Elias, Matz, Tiernan & Herrick L.L.P. is not binding
on the IRS. Stockholders should also be aware that some of the tax consequences
of the Merger are governed by provisions of the Code as to which there are no
final regulations and little or no judicial or administrative guidance. The
opinion of Elias, Matz, Tiernan & Herrick L.L.P. is based upon the federal
income tax laws as in effect on the date of such opinion and as those laws are
currently interpreted. There can be no assurance that future legislation,
regulations, administrative rulings or court decisions will not adversely affect
the accuracy of the statements contained herein.

      The federal income tax consequences discussed below are conditioned upon,
and the opinion of Elias, Matz, Tiernan & Herrick L.L.P. is based upon, the
accuracy as of the date hereof and at, as of and after the Effective Time of the
Merger of certain assumptions, including, but not limited to, the following
(taking into account for purposes hereof all of the events which are
contemplated under the Merger Agreement): (A) that, pursuant to the Merger, the
holders of THB Common Stock receive shares of PennFirst Common Stock having a
value as of the Effective Time of the Merger of not less than fifty percent
(50%) of the value of the THB Common Stock as of the same date; (B) that
following the Merger, PennFirst will continue the historic business of THB or
use a significant portion of THB's historic business assets in a business; and
(C) that a bona fide corporate business purpose exists for the Merger.

      PennFirst and THB believe that all of the foregoing assumptions are
accurate as of the date hereof, and will be accurate at, as of and after the
Effective Time of the Merger. If either PennFirst or THB learns before the
Effective Time of the Merger that such assumptions are false and that its
counsel therefore believes that the Merger is unlikely to be treated as a
tax-free reorganization, then additional stockholder approval will be obtained
before consummation of the Merger.

      Elias, Matz, Tiernan & Herrick L.L.P. has rendered an opinion to PennFirst
and THB, based upon the assumptions set forth herein, that the Merger will have
the following federal income tax consequences: (i) no gain or loss will be
recognized by PennFirst or THB as a result of the Merger; (ii) no gain or loss
will be recognized by any stockholder of THB upon the exchange of that holder's
shares of THB Common Stock solely for shares of PennFirst Common Stock pursuant
to the Merger; (iii) stockholders of THB will recognize gain with respect to the
cash portion of the Merger Consideration (the "Cash Consideration") received,
but not in excess of the amount of the Cash Consideration received; (iv) the
basis of the shares of PennFirst Common Stock received by a stockholder of THB
(including any fractional shares) will be the same as the basis of the shares of
THB


                                      -45-
<PAGE>

Common Stock surrendered in exchange therefor (a) decreased by the amount of the
Cash Consideration, and (b) increased by (1) the amount, if any, of the Cash
Consideration that was treated as a dividend, and (2) the amount of gain
recognized by that stockholder on the exchange (not including any portion of
such gain that is treated as a dividend); (v) if shares of THB Common Stock were
capital assets in the hands of the THB stockholder immediately prior to the
Merger, the holding period of the shares of PennFirst Common Stock received by
that stockholder in the Merger will include the holding period of the shares of
THB Common Stock surrendered in exchange therefor; (vi) a stockholder of THB who
dissents from the proposed Merger and receives solely cash in exchange for that
stockholder's shares of THB Common Stock will be treated as having received that
cash as a distribution in redemption of those shares subject to the provisions
and limitations of Section 302 of the Code. If the distribution is eligible for
treatment as a distribution in redemption of that stockholder's shares, that
stockholder will have gain to the extent of the consideration received less that
stockholder's adjusted basis in those shares; and (vii) the receipt by a
stockholder of THB of cash in lieu of a fractional share of PennFirst Common
Stock will be treated as if that fractional share was issued to that holder in
the Merger and thereafter redeemed by PennFirst for cash. That receipt of cash
by a stockholder will be treated as a distribution by PennFirst in full payment
in exchange for the fractional share as provided in Section 302(a) of the Code.
If the distribution is eligible for treatment as a distribution in redemption of
a stockholder's fractional share, that stockholder will have gain to the extent
of the consideration received less that stockholder's allocable adjusted basis
in that fractional share.

      If the shares of THB Common Stock exchanged are a capital asset, any gain
recognized will be capital gain to the extent described below. The capital gain
will be long-term if the shares of THB Common Stock have been held by the
applicable stockholder for more than one year. The determination of whether a
stockholder would recognize a capital gain and/or dividend income is made by
reference to the redemption rules of Section 302 of the Code. Under Section 302,
all of the cash representing gain recognized on the exchange will be taxed as
capital gain if the deemed redemption is a "substantially disproportionate
redemption" of stock with respect to a stockholder or is "not essentially
equivalent to a dividend." For this purpose, the Merger will be viewed as if
each stockholder had received only PennFirst Common Stock in the Merger and as
if PennFirst had thereafter redeemed appropriate portions of the PennFirst
Common Stock in exchange for the cash received by that stockholder. The deemed
redemption is a "substantially disproportionate redemption" if that
stockholder's deemed percentage share of the outstanding PennFirst Common Stock
after the Merger but before the deemed redemption is reduced by more than 20% as
a result of the deemed redemption. The deemed redemption is "not essentially
equivalent to a dividend" if that stockholder experiences a "meaningful
reduction" in his proportionate interest in PennFirst by reason of the deemed
redemption. In general, there are no fixed rules for determining when a
meaningful reduction has occurred.


                                      -46-
<PAGE>

      In determining whether a stockholder has a "substantially disproportionate
redemption" or experiences a "meaningful reduction" in his proportionate
interest in PennFirst, shares of PennFirst Common Stock which are considered to
be owned by the stockholder pursuant to certain constructive stock ownership
rules set forth in Section 318 of the Code, as well as shares actually owned,
must be taken into account. In general, under Section 318, a stockholder
constructively owns any stock which that stockholder has an option to acquire,
or any stock owned directly or indirectly by (1) that stockholder's spouse
(unless legally separated under court decree), children, grandchildren or
parents; (2) a partnership, trust or estate in which that stockholder has an
interest to the extent of that stockholder's interest; or (3) a corporation to
the extent of that stockholder's interest, but only if that stockholder actually
or constructively owns 50% or more in value of the corporation's stock. Also, a
stockholder that is a partnership, trust or estate will be considered to own
stock owned by its partners, grantors or beneficiaries, as the case may be, and
a stockholder which is a corporation will be considered to own stock owned by
any of its stockholders who owned 50% or more in value of the corporation's
stock. An S corporation and its stockholders are treated as if they were a
partnership and partners, respectively. In many instances, stock owned
constructively as a result of the attribution rules can be attributed again to
another (for example, stock owned due to family attribution can further be
attributed to a partnership), but in other circumstances, there is no "double"
attribution.

      If any of the cash received by a stockholder has the effect of a dividend,
the portion of the gain recognized equal to that stockholder's share of
undistributed corporate earnings and profits is treated as dividend income and
the balance of the gain is capital gain. It is unclear whether it is the
earnings and profits of THB which are considered or some combination of those of
THB and PennFirst. It is possible that the cash distributed might exceed the
applicable earnings and profits. No loss will be recognized.

      Unless an exception is available under applicable law or regulations, 31%
of the cash portion of the Merger Consideration payable to a stockholder will be
withheld unless that payee provides a tax identification number (social security
number or employer number) and certifies that such number is correct on a Form
W-9 which will be provided with the letter of transmittal that will be used to
exchange shares of THB Common Stock for the Merger Consideration.

Accounting Treatment of the Merger

      The Merger will be accounted for as a purchase for financial reporting
purposes. Under this method of accounting, PennFirst will record the acquisition
of THB at its cost at the Effective Time of the Merger, which cost would include
the cash paid in the Merger, the fair value of the shares of PennFirst Common
Stock issued in the Merger and all direct acquisition costs. The acquisition
costs will be allocated to the acquired assets and liabilities of THB based upon
their fair values at the Effective Time of the Merger in accordance with
generally accepted accounting principles. Acquisition costs in excess of the
fair values of


                                      -47-
<PAGE>

the net assets acquired, if any, will be recorded as an intangible asset and
amortized over a period of 15 years for financial accounting purposes. The
reported income of PennFirst will include the operations of THB after the
Effective Time of the Merger. See "Unaudited Pro Forma Condensed Combined
Financial Information."

Dissenters' Rights

      Any owner of shares of THB Common Stock has the right under Subchapter 15D
of the BCL to object to the Merger and demand to be paid in cash the fair value
of such shares upon complying in full with the provisions of Subchapter 15D. The
following does not purport to be a complete statement of the provisions of
Subchapter 15D or Section 1930 of the BCL and is qualified in its entirety by
reference to those provisions, a copy of which is attached hereto as Appendix D.
Such provisions must be strictly complied with or a stockholder's dissenters'
rights will be lost.

      If an owner of shares of THB Common Stock wants to exercise the right to
dissent, such owner must satisfy all the following conditions: (a) the owner
must file with THB prior to the vote with respect to the Merger a written notice
of his intention to demand that he be paid the fair value of his shares of THB
Common Stock if the Merger takes place (neither a vote in person or by proxy
against adoption and approval of the Merger Agreement nor an abstention from
voting with respect to, or a failure to vote for adoption and approval of, the
Merger Agreement will constitute such a written notice.); (b) the owner must not
effect any change in the beneficial ownership of his shares of THB Common Stock
from the date of filing such written notice continuously through the Effective
Time of the Merger; and (c) the owner must not vote in person or by proxy for
adoption and approval of the Merger Agreement. (Neither an abstention from
voting with respect to, nor a failure to vote in person or by proxy against
adoption and approval of, the Merger Agreement will constitute a vote for
adoption and approval of the Merger Agreement.) Unless an owner follows all
these steps, he will not acquire any right to payment of the fair value of his
shares and will be conclusively presumed to have consented to the Merger and
will be bound by its terms. A written notice of an intention to demand payment
of fair value should be sent prior to the THB Special Meeting to Troy Hill
Bancorp, Inc., 1706 Lowrie Street, Pittsburgh, Pennsylvania 15212, Attention:
Secretary.

      A person who is the beneficial owner, but not the record holder, of shares
of THB Common Stock and who desires to exercise the rights of a dissenting
stockholder may assert those rights with respect to shares held on that person's
behalf. Such a person will be treated as a dissenting stockholder if he submits
to THB a written consent of the record holder of those shares to such treatment
no later than the time dissenters' rights are asserted with respect to those
shares. A beneficial owner may not dissent with respect to less than all shares
of which such person is the owner, whether or not the shares so owned are
registered in such person's name.


                                      -48-
<PAGE>

      A record holder for more than one beneficial owner may assert dissenters'
rights as to less than all of the shares registered in his name only if that
holder dissents with respect to all shares beneficially owned by a person that
are held by him and discloses the name and address of that person. In that
event, the record holder will be treated as if the shares as to which he has
dissented and the other shares held by him were registered in the names of
different persons.

      If the Merger Agreement is adopted and approved by the requisite vote of
the stockholders of PennFirst and THB, THB or PennFirst, as the surviving
corporation, will mail a "further notice" to each owner who followed all of the
steps described above (a "Dissenter"). The "further notice" will (i) state the
location where and the date by which a demand for payment must be sent and
certificates formerly representing shares of THB Common Stock ("Certificates")
must be deposited in order to obtain payment, which date will not be less than
30 days after the date of mailing of the "further notice", (ii) supply a form
for demanding payment that includes a request for certification of the date on
which the Dissenter acquired beneficial ownership of his shares of THB Common
Stock, and (iii) include a copy of Subchapter 15D of the BCL. If a Dissenter
fails to timely demand payment or to timely deposit his Certificates as required
by the "further notice," that person will not have any right to receive payment
of the fair value of his shares.

      If the Merger has not been consummated within 60 days after the date
specified in the "further notice" for demanding payment and depositing
Certificates, THB will return any deposited Certificates. At any time
thereafter, THB or PennFirst, as the surviving corporation, may send a new
"further notice" containing the provisions described above to all Dissenters.

      Promptly after the Effective Time of the Merger, or upon timely receipt of
demand for payment if the Merger has already occurred, PennFirst will either (i)
pay the amount that PennFirst estimates is the fair value of the Dissenters'
shares to the Dissenters who timely made demand for payment and timely deposited
their Certificates, or (ii) provide written notice to those Dissenters that no
payment will be made. This payment or written notice will be accompanied by a
closing balance sheet and statement of income of THB for a fiscal year ending
not more than 16 months before the date of payment or notice, the latest
available interim financial statements of THB, a statement of PennFirst's
estimate of the fair value of the Dissenters' shares, a notice of the right of a
Dissenter to demand payment or supplemental payment, as the case may be, and a
copy of Subchapter 15D of the BCL. If PennFirst does not pay its estimate of the
fair value of the shares of THB Common Stock of any Dissenter, it must return
his deposited Certificates to him. PennFirst may make a notation on any returned
Certificate that a demand for payment of fair value with respect to that
Certificate has been made. If that Certificate is transferred, any new
Certificate will bear a similar notation, together with the name of the original
dissenting holder or owner thereof. A transferee will not acquire by transfer
any rights other than those that the original Dissenter had after making demand
for payment of fair value.


                                      -49-
<PAGE>

      If a Dissenter believes that PennFirst's estimate of the fair value of his
shares of THB Common Stock is less than their fair value, that Dissenter should
send PennFirst his own estimate of their fair value. A Dissenter's estimate will
constitute a demand for payment of his estimate of the fair value of his shares
of THB Common Stock or for payment of the difference between the two estimates
if PennFirst has paid that Dissenter its estimate. If a Dissenter does not file
with PennFirst his own estimate within 30 days after the mailing to him of the
payment of PennFirst's estimated fair value or its written notice thereof, that
Dissenter will not be entitled to receive any amount greater than the payment
remitted by PennFirst or the amount stated in that notice.

      Within 60 days after the latest of (i) the Effective Time of the Merger,
(ii) timely receipt of any demands for payment of fair value in response to a
"further notice," or (iii) timely receipt of a Dissenter's estimate of the fair
value of his shares of THB Common Stock, if any demand for payment remains
unsettled, PennFirst may file an application for relief in the Court of Common
Pleas of Allegheny County, Pennsylvania (the "County Court"), requesting that
the fair value of the remaining Dissenters' shares be determined. All Dissenters
whose demands for payment of the fair value of their Dissenters' shares have not
been settled will be made parties to such proceeding. Each Dissenter who is made
a party to such proceeding will be entitled to recover the amount by which the
fair value of his Dissenters' shares exceeds any amount previously paid to that
Dissenter by PennFirst for his shares, plus interest. If PennFirst fails to file
an application with the County Court prior to the expiration of that 60-day
period, any Dissenter who has made a demand for payment of the fair value of his
Dissenters' shares, and has not already settled his claim against PennFirst may
file an application with the County Court in the name of PennFirst within 30
days of the expiration of that 60-day period. If no such Dissenter files an
application within that 30-day period, all remaining Dissenters will be paid
PennFirst's estimate of the fair value of their Dissenters' shares and will not
be entitled to any additional amounts. In any proceeding before the County
Court, the fair value of the Dissenters' shares to be determined by the County
Court is the fair value of those shares immediately prior to the Effective Time
of the Merger, taking into account all relevant factors, but excluding any
appreciation or depreciation in anticipation of the Merger.

      The costs and expenses of any proceeding to determine the fair value of
the remaining Dissenters' shares will be determined by the County Court and
assessed against PennFirst, although all or any part of those costs and expenses
may be apportioned and assessed as the County Court deems appropriate against
any Dissenters who are parties to the proceeding and whose actions in demanding
supplemental payments the County Court finds to be dilatory, obdurate,
arbitrary, vexatious or in bad faith. The fees and expenses of counsel and
experts for the respective parties may be assessed as the County Court deems
appropriate against PennFirst and in favor of any or all Dissenters if PennFirst
failed to comply substantially with the requirements of Subchapter 15D and may
be assessed against PennFirst or any Dissenter, in favor of any other party, if
the County Court finds that the party against whom the fees and expenses are
assessed acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious
manner in respect to the rights provided by Subchapter 15D.


                                      -50-
<PAGE>

If the County Court decides that any Dissenter's counsel provided substantial
benefits to other Dissenters, but that the fees of such counsel should not be
assessed against PennFirst, then the County Court may award that counsel
reasonable fees to be paid out of the amounts awarded to those other Dissenters.

      It is a condition to PennFirst's obligation to consummate the Merger that
the number of Dissenters' shares be less than 15% of the THB Common Stock
immediately prior to the Effective Time. See "The Merger - Conditions to the
Merger." PennFirst has reserved the right to waive this condition at any time.

Expenses of the Merger

      The Merger Agreement provides that PennFirst and THB shall each bear and
pay all costs and expenses incurred by it in connection with the transactions
contemplated by the Merger Agreement, including, without limitation, legal,
accounting, investment banking and printing expenses, provided, however, that
PennFirst shall bear all costs of printing, mailing and filing, as applicable,
the Registration Statement, this Joint Proxy Statement/Prospectus and all other
registration and filing fees relating to the Merger.

      In order to increase the likelihood that the transactions contemplated by
the Merger Agreement will be consummated, the Merger Agreement provides that in
the event that, (x) PennFirst's Board of Directors fails to recommend to its
stockholders the approval of the Merger Agreement and such stockholders fail to
approve the Merger Agreement or (y) PennFirst fails to duly hold a meeting of
its stockholders for the purpose of voting on the Merger Agreement, then
PennFirst will promptly reimburse THB for its out-of-pocket costs and expenses
(documented with reasonable specificity) incurred by THB in connection with
entering into the Merger Agreement and carrying out any and all acts
contemplated thereunder up to a maximum amount of $150,000 and shall also
promptly pay THB a termination fee of $150,000.

Option Agreement

      In fulfillment of a condition to PennFirst's execution of the Merger
Agreement, PennFirst and THB entered into an Option Agreement, a copy of which
is attached to this Joint Proxy Statement/Prospectus as Appendix B and is
incorporated by reference herein. The following summary is qualified in its
entirety by reference to the full text of the Option Agreement.

      Pursuant to the Option Agreement, THB granted to PennFirst an option to
purchase up to an aggregate of 213,000 shares of authorized but unissued THB
Common Stock (representing 19.9% of the outstanding THB Common Stock as of the
date of the Option Agreement) at a price of $15.75 per share upon the occurrence
of certain triggering events, subject to the receipt of any required approvals
of applicable regulatory authorities. The exercise price of the PennFirst Option
and the number of shares subject to the PennFirst


                                      -51-
<PAGE>

Option are subject to anti-dilution provisions. The Option Agreement is intended
to increase the likelihood that the Merger will be consummated in accordance
with its terms by making it more difficult and more expensive for a third party
to acquire control of THB.

      Pursuant to the Option Agreement, the PennFirst Option is exercisable only
upon the occurrence of a Purchase Event (as defined below). A Purchase Event
means any of the following events: (i) THB or any of its subsidiaries shall have
entered into an agreement with any person (other than PennFirst or any
subsidiary thereof) (A) to merge, consolidate or enter into any similar
transaction with such person, (B) for the disposition, by sale, lease, exchange
or otherwise, of all or substantially all of the consolidated assets or deposits
of THB or (C) for the issuance, sale or other disposition of securities
representing 15% or more of the voting power of THB or any of its subsidiaries;
(ii) any person (other than PennFirst or any subsidiary thereof) shall have
acquired beneficial ownership of, or any group of persons shall have been formed
which beneficially owns, 15% or more of the THB Common Stock (clauses (i) and
(ii) above are collectively referred to as an "Acquisition Transaction"); (iii)
any person (other than PennFirst or any subsidiary thereof) shall have commenced
a tender offer or exchange offer to purchase or otherwise acquire control of 15%
or more of the THB Common Stock (a "Tender Offer" or "Exchange Offer,"
respectively); (iv) THB's stockholders shall have failed to approve the Merger
Agreement at a meeting called for such purpose or such meeting shall not have
been held or shall have been cancelled prior to the termination of the Merger
Agreement in accordance with its terms or THB's Board of Directors shall have
withdrawn, or modified in a manner which is adverse to PennFirst, the
recommendation of THB's Board of Directors with respect to the Merger Agreement
after it shall have been publicly announced that any person (other than
PennFirst or any subsidiary thereof) shall have (A) commenced a Tender Offer or
filed a registration statement under the Securities Act with respect to an
Exchange Offer, (B) made, or disclosed an intention to make, a proposal to
engage in an Acquisition Transaction, (C) filed an application (or given
notice), whether in draft or final form, under the Bank Holding Company Act of
1956, the HOLA, the Bank Merger Act or the Change in Bank Control Act of 1978,
for approval to engage in an Acquisition Transaction or (D) any person shall
have solicited proxies in a proxy solicitation subject to Regulation 14A under
the Exchange Act in opposition to approval of the Merger Agreement by THB's
stockholders.

      The Option Agreement further provides that, if requested by PennFirst, THB
shall promptly prepare and file a registration statement with the Commission,
covering the number of shares of THB Common Stock purchased by PennFirst
pursuant to the Option Agreement as PennFirst shall specify in order to permit
the public sale or other disposition of such shares. THB will use its best
efforts to cause such registration statement to remain effective for a period of
at least 180 days. PennFirst will have the right to request two such
registration statements.

      The Option Agreement terminates in accordance with its terms on the date
on which occurs the earliest of: (i) immediately prior to the Effective Time,
(ii) 12 months after the


                                      -52-
<PAGE>

first occurrence of a Purchase Event, (iii) 12 months after the termination of
the Merger Agreement by PennFirst pursuant to Section 6.01(d) thereof prior to
the occurrence of a Purchase Event, and (iv) a termination of the Merger
Agreement in accordance with its terms (other than by PennFirst pursuant to
Section 6.01(d) thereof) prior to the occurrence of a Purchase Event.

Stockholders Agreement

      In conjunction with the Merger Agreement and the Option Agreement,
PennFirst has also entered into a Stockholders Agreement with each of the
directors and certain officers of THB and Troy Hill. Pursuant to such
Stockholders Agreement, the directors and certain officers of THB have agreed,
among other things, not to sell, pledge, transfer or otherwise dispose of his or
her shares of THB Common Stock prior to the final voting record date established
in connection with the THB Special Meeting and to vote such shares of THB Common
Stock in favor of the Merger Agreement, and against any plan or proposal
pursuant to which THB is to be acquired by or merged with, or pursuant to which
THB or Troy Hill proposes to sell all or substantially all of its assets and
liabilities to, any person, entity or group (other than PennFirst or any
affiliate thereof).

                     UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL INFORMATION

      The unaudited pro forma condensed combined financial information set forth
below should be read in conjunction with the historical consolidated financial
statements, including the notes thereto, of PennFirst that are incorporated by
reference in this Joint Proxy Statement/Prospectus (see "Incorporation of
Certain Documents by Reference" and "PennFirst Selected Consolidated Financial
Information") and the historical consolidated financial statements of THB,
including the notes thereto, of THB included elsewhere herein (see "Index to THB
Consolidated Financial Statements" and "THB Selected Consolidated Financial
Information"). The unaudited pro forma condensed combined financial information
set forth below gives effect to the Merger under the purchase accounting method.
The pro forma condensed combined balance sheet treats the Merger as if it had
been consummated on September 30, 1996, and the pro forma condensed combined
statements of income treat the Merger as if it has been consummated at the
beginning of the respective periods. The pro forma combined per share data gives
effect to the assumed issuance of 985,687 shares of PennFirst Common Stock,
which assumes that the Per Share Stock Consideration consists of 0.923 shares of
PennFirst Common Stock and that none of the outstanding stock options to
purchase THB Common Stock are exercised.

      This pro forma financial information is presented for illustrative
purposes only and is not necessarily indicative of the operating results or
financial position that would have occurred if the Merger had been consummated
at the dates assumed for purposes hereof, nor is it necessarily indicative of
future operating results or financial position.

*     Represents less than 1% of the outstanding THB Common Stock.

(1)   For purposes of this table, pursuant to rules promulgated under the
      Exchange Act, an individual is considered to beneficially own shares of
      THB 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, a
      director has sole voting power and sole investment power with respect to
      the indicated shares.

(2)   The Troy Hill Bancorp, Inc. Employee Stock Ownership Trust ("Trust") was
      established pursuant to the THB ESOP by an agreement between THB and Ellry
      N. Davis, Joseph W. Snyder and Raymond K. Aiken, who act as trustees of
      the plan ("Trustees"). As of the THB Record Date, 20,428 shares held in
      the Trust had been allocated to the accounts of participating employees.
      Under the terms of the THB ESOP, the Trustees must vote all allocated
      shares held in the THB ESOP in accordance with the instructions of the
      participating employees, and allocated shares for which employees do not
      give instructions and unallocated shares will be voted in the same ratio
      on any matter as to those shares for which instructions are given. The
      amount of THB Common Stock beneficially owned by each individual trustee
      or all directors and executive officers as a group does not include the
      shares held by the Trust.

(3)   Consists of shares with respect to which Wellington Management Company
      ("WMC") shares dispositive power and which are owned by numerous
      investment counselling clients and, consequently, may be deemed to be
      beneficially owned by WMC.

(4)   In connection with the execution of the Merger Agreement, THB granted
      PennFirst an option to purchase up to 213,000 shares of THB Common Stock
      upon the occurrence of certain events, none of which has occurred as of
      the date hereof. See "The Merger - Option Agreement." Because the
      PennFirst Option is not currently exercisable, PennFirst has disclaimed
      beneficial ownership of the shares subject to such option. The shares
      subject to the Option Agreement represent 19.9% of the THB Common Stock
      outstanding as of the THB Record Date (after giving effect to the exercise
      of the PennFirst Option described above).

(5)   Includes 4,496 shares which are subject to stock options and are
      exercisable within 60 days and 2,698 shares which were awarded to Mr.
      Thaner pursuant to THB's Recognition and Retention Plan and Trust ("RRP")
      and which had not vested as of the THB Record Date. Does not include
      26,382 shares beneficially owned by Edwin A. Thaner, Mr. Thaner's son.

(6)   Includes 3,000 shares held by Mr. Aiken's wife, which shares may be deemed

      shares which were awarded to Mr. Aiken pursuant to THB's RRP and which had

income, which is determined by the difference between interest and dividend
income on interest-earning assets, principally loans, mortgage-backed securities
and investment securities, and interest expense on interest-bearing liabilities,
which principally consist of deposits and borrowings. THB's net income also is
affected by its provision for loan losses, as well as the level of its
noninterest income, including loan service charges, gain on sale of loans, and
other income, and its noninterest expenses, such as salaries and employee
benefits, occupancy expense, federal deposit insurance and miscellaneous other
expenses, and income taxes.

      In general, financial institutions are vulnerable to an increase in
interest rates to the extent that interest-bearing liabilities mature or reprice
more rapidly than interest-earning assets. The lending activities of financial
institutions, including Troy Hill, have historically emphasized the origination
of long-term, fixed-rate loans secured by single-family residences, and the
primary source of funds of such institutions has been deposits, which largely
mature or are subject to repricing within a short period of time. This factor
has historically caused the income earned by Troy Hill on its loan portfolio to
adjust more slowly to changes in interest rates than its cost of funds. While
having liabilities that reprice more frequently than assets is generally
beneficial to net interest income in times of declining interest rates, such an
asset/liability mismatch is generally detrimental during periods of rising
interest rates. To reduce the effect of adverse changes in interest rates on its
operations, THB has implemented the asset and liability management policies
described below.

Asset and Liability Management

      THB maintains a program designed to monitor its exposure to material and
prolonged increases in interest rates. The principal determinant of the exposure
of THB's earnings to interest rate risk is the timing difference between the
repricing or maturity of THB's interest-earning assets and the repricing or
maturity of its interest-bearing liabilities. As described below, THB's asset
and liability management policies have increased THB's interest rate sensitivity
primarily by shortening the maturities of THB's interest-earning assets. To the
extent possible, THB also attempts to extend the maturities of its
interest-bearing liabilities. THB's Board of Directors establishes and monitors
THB's asset and liability management policies.

      THB has adopted a strategy designed to improve the interest rate
sensitivity of its assets relative to its liabilities. The primary elements of
this strategy include: (i) maintaining a high level of liquid assets that can be
reinvested in higher yielding investments should interest rates rise; (ii)
emphasizing investment in (A) shorter-term (15 years or less), fixed-rate
single-family residential loans and (B) residential construction and commercial
real estate loans, which generally have adjustable interest rates and/or shorter
maturities than traditional single-family residential loans;


                                      -63-

(iii) to the extent market conditions permit, increasing the origination of
adjustable-rate single-family residential loans ("ARMs"); (iv) maintaining the
weighted average maturity of THB's investment portfolio at five years or less;
and (v) selling newly originated loans with maturities of greater than fifteen
years.

      As of September 30, 1996, the implementation of these asset and liability
initiatives resulted in the following: (i) $18.6 million or 22.2% of THB's total
loan portfolio had adjustable interest rates or maturities of less than 12
months; (ii) $1.2 million or 48.6% of THB's portfolio of mortgage-backed
securities were secured by ARMs; and (iii) $5.1 million or 81.0% of THB's
investment securities portfolio had scheduled maturities of five years or less.

Changes in Financial Condition

      General. At September 30, 1996, THB's total assets amounted to $99.5
million, compared to $92.2 million at June 30, 1996 and $75.1 million at June
30, 1995. Total assets increased by $7.3 million or 7.9% from June 30, 1996 to
September 30, 1996 and by $17.1 million or 22.8% from June 30, 1995 to June 30,
1996. The increases were primarily due to increases of loans receivable which
was primarily due to increased relationships with real estate brokers. These
increases were partially offset by decreases in investment and mortgage-backed
securities (including securities available for sale) which was the result of THB
selling a portion of its investments to fund the increase in loans.

      Investments in Debt and Equity Securities. In May 1993, the Financial
Accounting Standards Board ("FASB") released SFAS No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." SFAS No. 115 addresses the
accounting and reporting for investments in equity securities that have readily
determinable fair values and all investments in debt securities. Investments are
to be classified into the following three categories: 1) Debt Securities that
THB has the positive intent and ability to hold to maturity are classified as
held to maturity securities and reported at amortized cost; 2) Debt and Equity
Securities that are bought and held principally for the purpose of resale in the
near future are classified as trading securities and reported at fair value,
with unrealized gains and losses included in current period earnings; 3) Debt
and Equity Securities not classified as either held to maturity securities or
trading securities are classed as available for sale securities and reported at
fair value, with unrealized gains and losses excluded from earnings and reported
as a separate component of stockholders' equity, net of deferred taxes. THB
adopted SFAS No. 115 as of July 1, 1994.

      In November 1995, the FASB issued "A Guide to Implementation of Statement
115 on Accounting for Certain Investments in Debt and Equity Securities,
Questions and Answers." This guide permitted a one-time reassessment of the
appropriateness of the classifications of securities as available for sale or
held for investment. In December 1995, THB transferred approximately $6.9
million of investment securities with a market value of $6.8 million from the
held to maturity category to the securities available for sale category.
Concurrent with this redesignation, all but approximately $1.7 million of the
securities transferred were sold at a realized loss of $5,000.


                                      -64-
<PAGE>

      As a matter of policy, THB generally emphasizes lending activities in
order to enhance the weighted average yield on its interest-earning assets and,
thus, its results of operations. Investment securities (excluding securities
available for sale), which consist of U.S. Government and agency obligations and
corporate obligations, decreased by $7.3 million or 100.0% during the year ended
June 30, 1996, due primarily to the one-time transfer of securities referred to
in the preceding paragraph. At September 30, 1996, all of THB's investment
securities were classified as available for sale.

      Approximately $751,000 of equity securities were purchased by THB during
the fiscal year ended June 30, 1996 due to the tax benefits and higher yields
associated with these securities. The portfolio of equity securities primarily
consist of cumulative preferred equity stocks and are classified as available
for sale. No securities were purchase by THB during the three months ended
September 30, 1996.

      Mortgage-Backed Securities. Mortgage-backed securities, which consist
primarily of securities which are insured or guaranteed by the Federal Home Loan
Mortgage Corporation ("FHLMC"), the Federal National Mortgage Association
("FNMA") or the Government National Mortgage Association ("GNMA"), were all
classified as available for sale at September 30, and June 30, 1996. Such
securities decreased by $2.7 million or 53.2% during the three months ended
September 30, 1996 due primarily to the sale of $2.5 million of such securities,
and by $1.9 million or 28.7% during the year ended June 30, 1996. The decreases
reflected principal repayments and the selling of mortgage-backed securities to
finance the increase in loan volume.

      Loans Receivable. Loans receivable (including loans classified as held for
sale) amounted to $83.9 million at September 30, 1996 and $74.6 million and
$53.5 million at June 30, 1996 and 1995, respectively. Loans receivable
(including loans classified as held for sale) increased by $9.3 million or 12.5%
during the three months ended September 30, 1996 and by $21.1 million or 39.5%
during the year ended June 30, 1996. The increases were due to generally lower
interest rates which produced a higher market demand.

      Allowance for Loan Losses. At September 30, 1996, THB's allowance for loan
losses totaled $687,000, which represented a $27,000 increase from the level
maintained at June 30, 1996 and a $20,000 increase from the level maintained at
June 30, 1995. At September 30, 1996, THB's allowance represented approximately
 .76% of the gross loan portfolio and 76.5% of total nonperforming loans. At that
date, the ratio of total non-performing loans to total loans amounted to 0.99%,
as compared to 1.22% at June 30, 1996 and 3.39% at June 30, 1995. Although
management of THB believes that its allowance for loan losses at September 30,
1996 was adequate based on facts and circumstances available to it, there can be
no assurances that future additions to such allowance will not be necessary in
future periods, which could adversely affect THB's results of operations.


                                      -65-

      Deposits. Deposits totaled $52.7 million at September 30, 1996, compared
to $54.0 million at June 30, 1996 and $50.6 million at June 30, 1995. Deposit
accounts subject to daily repricing (passbook, money market deposit and NOW
accounts) amounted to $18.1 million at September 30, 1996, compared to $18.8
million and $18.9 million at June 30, 1996 and 1995, respectively. During the
three months ended September 30, 1996, certificates of deposit decreased by
$536,000 or 1.5%, compared to an increase in certificates of deposit of $3.4
million or 10.6% in fiscal 1996 compared to fiscal 1995. This increase is
primarily due to the opening of an additional full-service branch office during
fiscal 1995. Troy Hill has generally not engaged in sporadic increases or
decreases in interest rates paid or offered the highest rates available in its
deposit market except upon specific occasions when market conditions have
created opportunities to attract longer-term deposits.

      Borrowings. Borrowings, which consist primarily of advances from the FHLB
of Pittsburgh, amounted to $27.0 million at September 30, 1996 and $18.6 million
and $5.8 million at June 30, 1996 and 1995, respectively. The weighted average
rate on FHLB advances was 5.40% during the three months ended September 30, 1996
and 6.06% and 5.40% during the years ended June 30, 1996 and 1995, respectively.
The increase in borrowings were primarily utilized to fund loan demand.

      Stockholders' Equity. Stockholders' equity increased from $17.2 million at
June 30, 1995 to $18.0 million at both June 30, 1996 and September 30, 1996.
This increase was primarily due to the $1.1 million of net earnings recognized
during fiscal 1996 which was offset by $449,000 of dividends paid to the
stockholders and a decrease in the market value of $125,000 in securities
available for sale. Stockholders' equity also increased as a result of the
vesting of benefits pursuant to Troy Hill's employee stock benefit plans.

Results of Operations

      General. THB reported net earnings of $52,000 and $262,000 during the
three months ended September 30, 1996 and 1995, respectively. The $210,000 or
80.2% decrease in net earnings for the three months ended September 30, 1996, as
compared to the same period in the prior year, is primarily due to the $530,000
increase in noninterest expense which is primarily attributable to the $326,000
special one-time SAIF assessment and a $198,000 increase in interest expense,
which were partially offset by a $381,000 increase in total interest income and
a $136,000 decrease in income taxes. If not for this one-time assessment, net
earnings for the three months ended September 30, 1996 would have been $266,000
or a 1.5% increase over the 1995 quarter.

      THB reported net earnings of $1.1 million, $919,000 and $1.1 million for
fiscal 1996, 1995 and 1994, respectively. Net earnings during fiscal 1996
increased by $169,000 or 18.4% when compared to June 30, 1995. This increase in
net earnings resulted primarily from an increase of $401,000 in net interest
income and a $89,000 increase in total noninterest income, which was partially
offset by a $210,000 increase in the provision for loan losses, a $10,000
increase in income taxes and an increase of $101,000 in total noninterest
expense. Net earnings during fiscal 1995 increased $40,000 or 4.6% (before the
$200,000 cumulative effect of the change in


                                      -66-

accounting for income taxes recognized during the fiscal year ended June 30,
1994). The increase in net earnings resulted primarily from an increase of
$441,000 in net interest income, a $70,000 decline in the provision for loan
losses and a $22,000 decrease in income taxes, which was partially offset by a
$276,000 increase in total noninterest expense and a decrease of $217,000 in
total noninterest income.

      Net Interest Income. Net interest income is determined by THB's interest
rate spread (i.e., the difference between the yields earned on its
interest-earning assets and the rates paid on its interest-bearing liabilities)
and the relative amounts of interest-earning assets and interest-bearing
liabilities.

      Average Balances, Net Interest Income and Yields Earned and Rates Paid.
The following table presents for the periods indicated the total dollar amount
of interest from average interest-earning assets and the resultant yields, as
well as the interest expense on average interest-bearing liabilities, expressed
both in dollars and rates, and the net interest margin. All average balances are
based on month-end or quarter-end balances. Management does not believe that the
use of month-end or quarter-end balances instead of daily average balances has
caused any material differences in the information presented.

      Rate/Volume Analysis. The following table described the extent to which
changes in interest rates and changes in volume of interest-related assets and
liabilities have affected THB's interest income and expense during the periods
indicated. For each category of interest-earning assets and interest-bearing
liabilities, information is provided on changes attributable to (i) changes in
volume (change in volume multiplied by prior year rate), (ii) changes in rate
(change in rate multiplied by prior year volume), and (iii) total change in rate
and volume. The combined effect of changes in both rate and volume has been
allocated proportionately to the change due to rate and the change due to
volume.

      THB's net interest income increased by $183,000 or 23.3% during the three
months ended September 30, 1996 compared to the same period in 1995. THB's net
interest income increased by $401,000 or 13.4% during fiscal 1996 and increased
by $441,000 or 17.3% during fiscal 1995. The increase in net interest income
during fiscal 1996 was the result of an increase in interest income primarily
due to an increase in the average balance of loans receivable which was offset
by an increase in interest expense due primarily to an increase in the average
rate paid on deposits and on interest paid to the Federal Home Loan Bank of
Pittsburgh on borrowed money. The increase in net interest income during fiscal
1995 was the result of an increase in interest income primarily due to an
increase in the average balance of loans receivable, mortgage-backed securities
and investment securities which offset an increase in interest expense due
primarily to an increase in the average rate paid on deposits.

      Interest Income. Interest on loans increased by $474,000 or 38.7% for the
three months ended September 30, 1996, when compared with the same period in
1995. The increase in interest on loans was due primarily to an increase in the
balance of loans receivable for the three months ended September 30, 1996 when
compared to the same period in 1995. Interest income on loans increased by $1.4
million or 34.8% during fiscal 1996, and increased $302,000 or 8.3% during
fiscal 1995. The increase during fiscal 1996 was due to a $15.7 million increase
in the average balance of loans receivable and an increase of 4 basis points in
the average yield earned thereon (100 basis points equals 1%). The increase in
interest income on loans during fiscal 1995 was due to a $6.7 million increase
in the average balance of loans receivable which offset a decline of 69 basis
points in the average yield earned thereon.

      Interest on mortgage-backed securities decreased $27,000 or 23.3% during
the three months ended September 30, 1996 when compared with the same period in
1995. The decrease was due primarily to a decrease of $2.4 million in the
average balance of mortgage-backed securities outstanding for the three months
ended September 30, 1996 when compared to the same period in 1995. Interest
income on mortgage-backed securities decreased by $50,000 or 10.1% during fiscal
1996, and increased by $237,000 or 92.6% during fiscal 1995. The decrease during
fiscal 1996 was due to a decrease in the average balance of mortgage-backed
securities of $1.5 million which was partially offset by a 70 basis point
increase in the average yield earned thereon. The increase in interest income on
mortgage-backed securities during fiscal 1995 was due to the reinvestment of a
portion of the proceeds of THB's stock offering into mortgage-backed securities,
which resulted in an increase in the average balance of such securities of $3.8
million, which was partially offset by a 2 basis point decline in the average
yield earned thereon.

      Interest and dividends on investment securities and other interest-earning
assets (consisting primarily of U.S. Government and agency obligations,
corporate obligations, interest-bearing deposits and FHLB of Pittsburgh stock)
decreased by $66,000 or 36.5% during the three months ended September 30, 1996
when compared with the same period in 1995. The decrease was the result of the
sale of U.S. Government and agency obligations


                                      -70-
<PAGE>

to fund newly originated loans. Interest and dividends on investment securities
and other interest-earning assets decreased by $9,000 or 1.3% during fiscal 1996
and increased by $122,000 or 21.1% during fiscal 1995. The decrease during
fiscal 1996 was due primarily to a $1.3 million decrease in the average balance
of such investments, which was partially offset by an increase of 125 basis
points in the average yield earned thereon. The increase during fiscal 1995 was
due primarily to a $1.6 million increase in the average balance of such
investments together with an increase of 129 basis points in the average yield
earned thereon.

      Interest Expense. Interest expense on deposits, the largest component of
THB's interest-bearing liabilities, was relatively constant in the three months
ended September 30, 1996 compared to the same period in 1995 and increased by
$582,000 or 30.6% during fiscal 1996 and by $166,000 or 9.6% during fiscal 1995.
The increase during fiscal 1996 was due to an increase of 56 basis points in the
average rate paid thereon, and a $6.8 million increase in the average balance of
deposits outstanding. The increase in interest expense on deposits during fiscal
1995 was due to an increase of 37 basis points in the average rate paid thereon,
which offset a slight decline in the average balance of deposits outstanding.
The decrease in the average balance of deposits during fiscal 1995 was due
primarily to disintermediation (the outflow of deposits into competing
investment products), and the result of the customers of the Troy Hill
withdrawing their deposit accounts to purchase common stock of THB. The increase
in the average rate paid on deposits during fiscal 1996 and 1995 was due to a
competitive market and rising interest rates.

      THB's interest on borrowings (consisting of advances from the FHLB of
Pittsburgh) increased $199,000 or 161.8% during the three months ended September
30, 1996, when compared with the same period in 1995. The increase was due to an
increase in the average balance of such borrowings of $15.0 million during the
three months ended September 30, 1996 as compared to the same period in 1995.
Troy Hill reinvested these additional advances from the FHLB of Pittsburgh into
permanent and construction loans secured by single-family residences. Interest
expense on advances and other borrowings increased by $335,000 or 132.4% during
fiscal 1996 and increased by $54,000 or 27.1% during fiscal 1995. The increase
during fiscal 1996 was due to a $5.0 million increase in the average balance of
FHLB advances and an increase of 66 basis points in the average rate paid
thereon. The increase in such expense during fiscal 1995 was due to an increase
in the average balance of FHLB advances which were utilized to fund the increase
in loan demand.

      Provisions for Loan Losses. Provisions for loan losses are charged to
earnings to bring the total allowance to a level considered appropriate by
management based on historical experience, the volume and type of lending
conducted by Troy Hill, the status of past due principal and interest payments,
general economic conditions, particularly as they relate to Troy Hill's market
area, and other factors related to the collectibility of Troy Hill's loan
portfolio.


                                      -71-
<PAGE>

      THB established provisions for loan losses of $30,000 during the three
months ended September 30, 1996 and 1995 and $220,000, $10,000 and $80,000
during fiscal 1996, 1995 and 1994, respectively. The provisions during fiscal
1996 and 1994 were due, in part, to losses experienced with respect to certain
commercial leases which Troy Hill had purchased and losses on certain
single-family construction loans during the fourth quarter of 1996. In addition,
THB determined to increase its allowance for loan losses due to its increased
origination of residential construction loans, which generally involve a higher
level of risk as compared to single-family residential lending (and therefore
have the inherent risk of higher levels of losses) and increased loan
charge-offs of $184,000 in fiscal 1996.

      Noninterest Income. THB's noninterest income amounted to $59,000 during
the three months ended September 30, 1996 compared to $57,000 during the same
period in 1995. Total noninterest income increased by $89,000 or 73.6% during
fiscal 1996 due primarily to a $51,000 increase in the gain on sale of loans and
a $31,000 decrease in loss on the sale of investment securities. Total
noninterest income decreased by $217,000 or 64.2% during fiscal 1995 due
primarily to a $189,000 decrease in gain on sale of loans and a $36,000 loss on
sales of investment securities recognized during the year. The increase in
noninterest income during fiscal 1996 was due primarily to an increase in sales
of loans to financial institutions. The decrease in gain on sales of loans
during fiscal 1995 was due to an increase in market rates of interest which
resulted in a decline in loan demand with respect to 30- year mortgage loans.

      Noninterest Expense. Noninterest expense increased by $530,000 or 138.0%
during the three months ended September 30, 1996 when compared with the same
period in 1995. The increase is primarily due to the $326,000 one-time SAIF
assessment, expenses incurred with respect to the proposed merger with PennFirst
and expenses incurred for properties held in real estate owned through
foreclosure. Without the one-time SAIF assessment, THB's noninterest expense
would have increased by $204,000 or 53.1%. Total noninterest expense increased
by $101,000 or 6.3% during fiscal 1996, as compared to the prior fiscal year.
The primary reason for the increase was due to a $92,000 increase in salaries
and employee benefits. This increase was partially offset by a $14,000 decrease
in miscellaneous other operating expenses (consisting primarily of office
supplies and services and legal and professional fees). Total noninterest
expense increased by $276,000 or 20.9% during fiscal 1995, due primarily to a
$161,000 or 26.8% increase in salaries and employee benefits, and a $127,000 or
28.2% increase in miscellaneous other operating expenses. The increase in
employee compensation and benefits during fiscal 1996 and 1995 was due to the
hiring of additional employees and the funding of THB's employee stock benefit
plans.

      Income Taxes. THB recognized $31,000 in income tax expense which reflected
an effective rate of 37.3% for the three months ended September 30, 1996, as
compared to $167,000 with an effective tax rate of 38.9% for the comparable 1995
period, due to lower pretax income. THB incurred income tax expense of $599,000,
$589,000 and $611,000 during fiscal 1996, 1995 and 1994, respectively. THB's
effective tax rate amounted to 35.5%, 39.1% and 41.0% during fiscal 1996, 1995
and 1994, respectively. The varied tax expense


                                      -72-
<PAGE>

reflects, among other things, the receipt of tax free interest dividend received
deductions, state taxes and other items during the periods.

      THB adopted SFAS No. 109 as of July 1, 1993. The general objective of SFAS
No. 109 is to recognize annually the deferred tax assets and liabilities which
will arise from future tax consequences of events that have been recognized in
THB's financial statements or tax returns. As a result of the adoption of SFAS
No. 109, THB recognized $200,000 in income during the year ended June 30, 1994
representing the cumulative effect of this change in accounting principle.

Liquidity and Capital Resources

      THB's liquidity, represented by cash and cash equivalents, is a product of
its operating, investing and financing activities. THB's primary sources of
funds are deposits, borrowings, amortization, prepayments, maturities of
outstanding loans, mortgage-backed securities and investment securities, sales
of loans, available for sale securities and other short-term investments and
funds provided from operations. While scheduled loan and mortgage-backed
securities amortization and maturing investment securities and short-term
investments are relatively predictable sources of funds, deposit flows and loan
prepayments are greatly influenced by general interest rates, economic
conditions and competition. THB manages the pricing of its deposits to maintain
a steady deposit balance. In addition, THB invests excess funds in overnight
deposits and other short-term interest-earning assets which provides liquidity
to meet lending requirements. THB has been able to generate enough cash through
an increase in advances from the FHLB of Pittsburgh and to a lesser extent,
growth in THB's deposit accounts. At September 30, 1996, THB had $27.0 million
of outstanding advances from the FHLB of Pittsburgh and a line of credit of $4.9
million, all of which is currently being utilized. Furthermore, Troy Hill has
access to the Federal Reserve Bank discount window.

      Liquidity management is both a daily and long-term function of business
management. Excess liquidity is generally invested in short-term investments
such as overnight deposits. On a longer-term basis, THB maintains a strategy of
investing in various lending products. THB uses its sources of funds primarily
to meet its ongoing commitments, to pay maturing savings certificates and
savings withdrawals, fund loan commitments and maintain a portfolio of
investment and mortgage-backed securities. At September 30, 1996, THB's total
approved loan commitments outstanding amounted to $3.8 million. At the same
date, commitments under unused lines of credit amounted to $3.0 million and the
unadvanced portion of construction loans approximated $5.2 million. Certificates
of deposit scheduled to mature in one year or less at September 30, 1996 totaled
$17.8 million. Management of THB believes that a significant portion of maturing
deposits will remain with Troy Hill.

      Federally insured savings institutions are required to maintain minimum
levels of regulatory capital. The OTS has established capital standards
applicable to all savings institutions. These standards generally must be as
stringent as the comparable capital requirements imposed on national banks. The
OTS also is authorized to impose capital requirements in excess of these
standards on individual institutions on a case-by-case basis.

      Savings institutions must satisfy three different OTS capital
requirements. Under these standards, savings institutions must maintain
"tangible" capital equal to at least 1.5% of adjusted total assets, "core"
capital equal to at least 3% of adjusted total assets and "total" capital (a
combination of core and "supplementary" capital) equal to at least 8% of
"risk-weighted" assets. For purposes of the regulation, core capital is defined
as common stockholders' equity (including retained earnings), noncumulative
perpetual preferred stock and related surplus, minority interests in the equity
accounts of fully consolidated subsidiaries, certain nonwithdrawable accounts
and pledged deposits and qualifying supervisory goodwill. Core capital is
generally reduced by the amount of a savings institution's intangible assets,
although limited exceptions to the deduction of intangible assets are provided
for purchased mortgage servicing rights, qualifying supervisory goodwill and
certain other intangibles, all of which are currently not relevant to the
calculation of Troy Hill's regulatory capital. Tangible capital is core capital
less all intangible assets, with a limited exception for purchased mortgage
servicing rights. Failure to meet minimum capital requirements can initiate
certain mandatory--and, possibly additional discretionary--actions by regulators
that, if undertaken, could have a direct material effect on THB's financial
statements.

      Quantitative measures established by regulation to ensure capital adequacy
require Troy Hill to maintain minimum amounts and ratios (set forth in the table
below) of Tangible and Core Capital (as defined in the regulations) to total
assets and of Total Capital (as defined) to risk-weighted assets (as defined).
Management believes, as of September 30, 1996, that Troy Hill meets all capital
adequacy requirements to which it is subject.

      As of September 30, 1996, the most recent notification from the Office of
Thrift Supervision (OTS) categorized Troy Hill as "well capitalized" under the
regulatory framework for prompt corrective action. There are no conditions or
events since that notification that management believes have changed the
institution's category.

                                 BUSINESS OF THB

      General. At September 30, 1996, Troy Hill's net portfolio of loans
receivable totalled $83.9 million, representing approximately 84.3% of its $99.5
million of total assets at that date. The principal lending activity of Troy
Hill is the origination of single-family residential loans and construction
loans primarily with respect to single-family residential properties. To a much
lesser extent, Troy Hill also originates multi-family residential and
nonresidential real estate loans, consumer loans and, prior to 1992, Troy Hill
purchased commercial leases from an investment consulting and loan servicing
firm located in Monroeville, Pennsylvania. Substantially all of Troy Hill's
mortgage loan portfolio consists of conventional mortgage loans, which are loans
that are neither insured by the Federal Housing Administration ("FHA") nor
partially guaranteed by the Department of Veterans Affairs ("VA").

      Historically, Troy Hill's lending activities have been concentrated in
single-family residential loans secured by properties located in its primary
market area of northern Allegheny and southern Butler counties, Pennsylvania.
Troy Hill has increased its emphasis in recent years in construction lending,
primarily on residential properties, in its primary market area. As discussed
under "- Construction Loans," construction lending generally, including
speculative lending to builders (where the property has not been pre-sold), is
generally considered to involve a higher level of risk as compared to
single-family residential lending. Troy Hill estimates that approximately 90% of
its mortgage loans are secured by properties located in Troy Hill's primary
market area.

      The Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA") imposed limitations on the aggregate amount of loans that a savings
institution could make to any one borrower, including related entities. Under
FIRREA, the permissible amount of loans-to-one borrower follows the national
bank standard for all loans made by savings institutions, which generally does
not permit loans-to-one borrower to exceed 15% of unimpaired capital and
surplus. Loans in an amount equal to an additional 10% of unimpaired capital and
surplus also may be made to a borrower if the loans are fully secured by readily
marketable securities. At September 30, 1996, Troy Hill's limit on loans-to-one
borrower under FIRREA was $2.1 million. At September 30, 1996, Troy Hill's five
largest loans or groups of loans-to-one borrower, including related entities,
ranged from an aggregate of $587,000 to $2.0 million, and are secured primarily
by single-family residential properties located in Troy Hill's primary market
area. All of Troy Hill's five largest loans or groups of loans were performing
in accordance with their terms at September 30, 1996.

      Scheduled contractual principal repayments do not reflect the actual
maturities of loans. The average maturity of loans is substantially less than
their average contractual terms because of prepayments and, in the case of
conventional mortgage loans, due-on-sale clauses, which generally give Troy Hill
the right to declare a loan immediately due and payable in the event, among
other things, that the borrower sells the real property subject to the mortgage
and the loan is not repaid. The average life of mortgage loans tends to increase
when current mortgage loan rates are substantially higher than rates on existing
mortgage loans and, conversely, decrease when rates on existing mortgages are
substantially higher than current mortgage loan rates (due to refinancings of
adjustable-rate and fixed-rate loans at lower rates). Under the latter
circumstances, the weighted average yield on loans decreases as higher yielding
loans are repaid or refinanced at lower rates.

      Origination, Purchase and Sale of Loans. The lending activities of Troy
Hill are subject to the written, non-discriminatory, underwriting standards and
loan origination procedures established by Troy Hill's Board of Directors and
management. Loan originations are obtained by a variety of sources, including
referrals from real estate brokers, developers, builders, existing customers,
newspaper, radio, periodical advertising and walk-in customers. Loan
applications are taken by lending personnel, and the loan department supervises
the obtainment of credit reports, appraisals and other documentation involved
with a loan. Property valuations are generally performed by independent outside
appraisers approved by Troy Hill's Board of Directors. Title and hazard
insurance are required on all security property.

      Loan applications are taken at either one of Troy Hill's offices. All loan
applications are required to be approved by Troy Hill's Loan Committee which
meets weekly. In addition, all loans committed or approved by Troy Hill are
reported to the full Board of Directors and ratified by such Board.

      Historically, Troy Hill has originated substantially all of the loans in
its portfolio and has held them until maturity. Nevertheless, Troy Hill's
residential loans are generally made on terms, conditions and documentation
which permit the sale to the Federal Home Loan Mortgage Corporation ("FHLMC"),
the Federal National Mortgage Association ("FNMA"), the Government National
Mortgage Association ("GNMA") and other institutional investors in the secondary
market. Since May 1993, Troy Hill has sold a majority of all long-term (over 15
years), fixed-rate single-family residential loans to institutional investors in
the secondary market as a means of minimizing interest rate risk as well as
generating additional funds for lending and other purposes. Sales of loans to
date generally have been under terms which do not provide any recourse to Troy
Hill by the purchaser in the event of default on the loan by the borrower.

      At September 30, 1996, loans purchased and serviced by others totalled
$1.8 million. Such loans consist primarily of seasoned single-family residential
loans, a substantial portion of which are secured by properties located outside
of Troy Hill's primary market area.

      Real Estate Lending Standards. Effective March 19, 1993, all financial
institutions were required to adopt and maintain comprehensive written real
estate lending policies that are consistent with safe and sound banking
practices. These lending policies must reflect consideration of the Interagency
Guidelines for Real Estate Lending Policies adopted by the federal banking
agencies in December 1992 ("Guidelines"). The Guidelines set forth uniform
regulations prescribing standards for real estate lending. Real estate lending
is defined as extension of credit secured by liens on interests in real estate
or made for the purpose of financing the construction of a building or other
improvements to real estate, regardless of whether a lien has been taken on the
property.

      The policies must address certain lending considerations set forth in the
Guidelines, including loan-to-value ("LTV") limits, loan administration
procedures, underwriting standards, portfolio diversification standards, and
documentation, approval and reporting requirements. These policies must also be
appropriate to the size of the institution and the nature and scope of its
operations, and must be reviewed and approved by the institution's board of
directors at least annually. The LTV ratio framework, with a LTV ratio being the
total amount of credit to be extended divided by the appraised value of the
property at the time the credit is originated, must be established for each
category of real estate loans. If not a first lien, the lender must combine all
senior liens when calculating this ratio. The Guidelines, among other things,
establish the following supervisory LTV limits: raw land (65%); land development
(75%); construction (commercial, multi-family and nonresidential) (80%);
improved property (85%); and one-to-four family residential (owner occupied) (no
maximum ratio; however any LTV ratio in excess of 90% should require appropriate
insurance or readily marketable collateral).

      Single-Family Residential Real Estate Loans. The primary lending activity
of Troy Hill is the origination of loans secured primarily by first mortgage
liens on existing single-family residences. At September 30, 1996, $59.8 million
or 66.1% of Troy Hill's total loan portfolio (including loans classified as held
for sale) consisted of single-family residential real estate loans,
substantially all of which are conventional loans.

      Historically, the single-family residential real estate loans originated
by Troy Hill have consisted primarily of fixed-rate loans. However, such loans
have generally been originated only under terms, conditions and documentation
which permit the sale thereof in the secondary market. At September 30, 1996,
approximately $46.6 million or 77.9% of the permanent single-family residential
loans in Troy Hill's loan portfolio consisted of loans which provide for fixed
rates of interest. Although these loans provide for repayments of principal over
a fixed period of up to 30 years, it is Troy Hill's experience that such loans
remain outstanding for a substantially shorter period of time. Since May 1993,
Troy Hill has sold a majority of all long-term (over 15 years), fixed-rate
single-family residential loans to institutional investors in the secondary
market.

      As economic and market conditions permit, Troy Hill has continued to offer
single-family residential loans which provide for periodic adjustments to the
interest rate. The adjustable-rate loans currently being originated by Troy Hill
have up to 30-year terms and an interest rate which


                                      -81-
<PAGE>

adjusts every year in accordance with a designated index (the weekly average
yield on U.S. Treasury securities adjusted to a constant comparable maturity of
one year, as made available by the Federal Reserve Board ("FRB"). There is a cap
on the amount of any increase or decrease in the interest rate per year, and
various caps, depending on when the loan was originated, on the amount which the
interest rate can increase or decrease over the life of the loan. Certain of
Troy Hill's adjustable-rate loans can, upon payment of a fee, be converted into
fixed-rate loans during certain specified periods. Troy Hill's adjustable-rate
loans currently being originated are not assumable and do not contain prepayment
penalties. Troy Hill has not engaged in the practice of using a cap on the
payments that could allow the loan balance to increase rather than decrease,
resulting in negative amortization.

      The demand for adjustable-rate loans in Troy Hill's primary market area
has been a function of several factors, including the level of interest rates,
the expectations of changes in the level of interest rates and the difference
between the interest rates and loan fees offered for fixed-rate loans and
adjustable-rate loans. The relative amount of fixed-rate and adjustable-rate
residential loans that can be originated at any time is largely determined by
the demand for each in a competitive environment. Due to the generally lower
rates of interest prevailing in recent periods, Troy Hill's originations of
adjustable-rate loans as a percentage of total loans have decreased as consumer
preference for fixed-rate loans has increased. At September 30, 1996,
approximately 22.1% of the permanent single-family residential loans in Troy
Hill's loan portfolio (including loans classified as held for sale) had
adjustable interest rates.

      Troy Hill is permitted to lend up to 100% of the appraised value of the
real property securing a residential loan (referred to as the loan-to-value
ratio); however, if the amount of a residential loan originated or refinanced
exceeds 90% of the appraised value, Troy Hill is required by federal regulations
to obtain private mortgage insurance on the portion of the principal amount that
exceeds 80% of the appraised value of the security property. Pursuant to
underwriting guidelines adopted by the Board of Directors, Troy Hill will lend
up to 95% of the appraised value of the property securing a single-family
residential loan, and generally requires borrowers to obtain private mortgage
insurance on the portion of the principal amount of the loan that exceeds 80% of
the appraised value of the security property.

      Property appraisals on the real estate and improvements securing Troy
Hill's single-family residential loans are made by independent appraisers
approved by Troy Hill's Board of Directors. Appraisals are performed in
accordance with federal regulations and policies. Troy Hill obtains title
insurance policies on the first mortgage real estate loans originated by it.
Borrowers also must obtain hazard insurance prior to closing and, when required
by the United States Department of Housing and Urban Development, flood
insurance. Borrowers may be required to advance funds, with each monthly payment
of principal and interest, to a loan escrow account from which Troy Hill makes
disbursements for items such as real estate taxes and mortgage insurance
premiums as they become due.

      Multi-Family Residential and Nonresidential Real Estate Loans. Troy Hill
originates mortgage loans for the acquisition and refinancing of existing
multi-family residential and nonresidential real estate properties. At September
30, 1996, $12.8 million or 14.1% of Troy Hill's total loan portfolio (including
loans classified as held for sale) consisted of loans secured by existing
multi-family residential real estate properties and $6.9 million or 7.7% of such
loan portfolio (including loans classified as held for sale) consisted of loans
secured by existing nonresidential real estate properties.

      The majority of Troy Hill's multi-family residential loans are secured
primarily by five to 20-unit apartment buildings, while nonresidential real
estate loans are secured primarily by office buildings and small retail
establishments. These types of properties constitute the majority of Troy Hill's
nonresidential real estate loan portfolio. Troy Hill's multi-family residential
and nonresidential real estate loan portfolio consists primarily of loans
secured by properties located in its primary market area.

      Although terms vary, multi-family residential and nonresidential real
estate loans generally are amortized over a period of up to 20 years and mature
in 15 years or less. Troy Hill will originate these loans either with fixed
interest rates or with interest rates which adjust in accordance with a
designated index, which generally is negotiated at the time of origination.
Loan-to-value ratios on Troy Hill's multi-family residential and nonresidential
real estate loans are currently limited to 85% or lower. As part of the criteria
for underwriting multi-family residential and nonresidential real estate loans,
Troy Hill generally imposes a specified debt coverage ratio (the ratio of net
cash from operations before payment of debt service to debt service). It is also
Troy Hill's general policy to obtain personal guarantees on its multi-family
residential and nonresidential real estate loans from the principals of the
borrower and, when this cannot be obtained, to impose more stringent
loan-to-value, debt service and other underwriting requirements.

      At September 30, 1996, Troy Hill's multi-family residential and
nonresidential real estate loan portfolio consisted of approximately 55 loans
with an average principal balance of $233,000. At September 30, 1996, all but
$184,000 of Troy Hill's multi-family residential and nonresidential real estate
loans were performing in accordance with their terms.

      Multi-family residential and nonresidential real estate lending entails
different and significant risks when compared to single-family residential
lending because such loans typically involve large loan balances to single
borrowers and because the payment experience on such loans is typically
dependent on the successful operation of the project or the borrower's business.
These risks can also be significantly affected by supply and demand conditions
in the local market for apartments, offices, warehouses or other commercial
space. Troy Hill attempts to minimize its risk exposure by limiting the extent
of the nonresidential lending generally. In addition, Troy Hill imposes
stringent loan-to-value ratios, requires conservative debt coverage ratios, and
continually monitors the operation and physical condition of the collateral.

      Construction Loans. In recent years, Troy Hill has been increasingly
active in originating loans to construct primarily single-family residences,
and, to a much lesser extent, loans to acquire and develop real estate for
construction of residential properties. These construction lending activities
generally are limited to Troy Hill's primary market area. At September 30, 1996,
construction loans amounted to $13.4 million or 14.8% of Troy Hill's total loan
portfolio (including loans classified as held for sale). As of such date, Troy
Hill's portfolio of construction loans consisted solely of loans for the
construction of single-family residences.

      Construction loans are made to individuals for the purpose of constructing
a personal residence or to local real estate builders and developers. Troy Hill
will underwrite construction loans to individuals on a construction/permanent
mortgage loan basis. In addition, approximately 15.7% of total outstanding
construction loans at September 30, 1996 were made to local real estate builders
and developers for the purpose of constructing primarily single-family homes for
which there were no contracts for sale at the time of origination. Upon
application, credit review and analysis of personal and corporate financial
statements, Troy Hill may grant local builders with whom it has done business
lines of credit up to designated amounts. These credit lines may be used for the
purpose of construction of speculative (or unsold) residential properties. Troy
Hill will generally limit the dollar amount of speculative construction loans
made to any one builder or developer to $750,000. Troy Hill may also, on a
case-by-case basis, grant a limited amount of land acquisition loans.

      Construction loans generally have maturities of 12 to 24 months, with
payments being made monthly on an interest-only basis. Thereafter, the permanent
financing arrangements will generally provide for either an adjustable or fixed
interest rate, consistent with Troy Hill's policies with respect to residential
and commercial real estate financing.

      Troy Hill intends to continue to increase its involvement in construction
lending within its primary market area. Such loans afford Troy Hill the
opportunity to increase the interest rate sensitivity of its loan portfolio.
Construction lending is generally considered to involve a higher level of risk
as compared to single-family residential lending, due to the concentration of
principal in a limited number of loans and borrowers and the effects of general
economic conditions on real estate developers and managers. Moreover, a
construction loan can involve additional risks because of the inherent
difficulty in estimating both a property's value at completion of the project
and the estimated cost (including interest) of the project. The nature of these
loans is such that they are generally more difficult to evaluate and monitor. In
addition, speculative construction loans to a builder are not necessarily
pre-sold and thus pose a greater potential risk to Troy Hill than construction
loans to individuals on their personal residences.

      Troy Hill has attempted to minimize the foregoing risks by, among other
things, limiting its construction lending primarily to residential properties.
In addition, Troy Hill has adopted underwriting guidelines which impose
stringent loan-to-value (85% with respect to single-family residential real
estate and 80% with respect to multi-family residential and nonresidential real
estate), debt service and other requirements for loans which are believed to
involve higher


                                      -84-
<PAGE>

elements of credit risk, by limiting the geographic area in which Troy Hill will
do business and by working with builders with whom it has established
relationships.

      Consumer Loans. Troy Hill offers consumer loans, although such lending
activity has not historically been a large part of its business. Troy Hill has
been originating consumer loans in recent years in order to provide a full range
of financial services to its customers and because such loans generally have
shorter terms and higher interest rates than mortgage loans. At September 30,
1996, $3.5 million or 3.8% of Troy Hill's total loan portfolio (including loans
classified as held for sale) consisted of consumer loans. The consumer loans
offered by Troy Hill include home equity and improvement loans, deposit account
secured loans and, to a much lesser extent, automobile loans. Most of Troy
Hill's consumer loans are secured and are primarily obtained through existing
and walk-in customers.

      In recent years, Troy Hill has placed increased emphasis on home equity
and improvement loans, which have increased from $1.3 million or 2.7% of total
loans receivable at June 30, 1994 to $3.4 million or 3.73% of total loans
receivable at September 30, 1996. Troy Hill intends to continue to increase its
origination of consumer loans, primarily home equity and improvement loans.

      Commercial Business Loans. At September 30, 1996, $1.0 million or 1.13% of
Troy Hill's total loan portfolio (including loans classified as held for sale)
consisted of commercial lease financings. During fiscal 1990, Troy Hill began to
purchase participation interests in pools of leases of general commercial
chattel from an investment consulting and loan servicing firm located in
Monroeville, Pennsylvania. Such commercial leases consisted generally of
furniture and equipment financing loans. Such commercial leases generally had
shorter terms and higher interest rates than traditional mortgage loans but also
involved a higher level of credit risk because of the type and nature of the
collateral and, in certain cases, the absence of collateral. In most cases, any
repossessed collateral for a defaulted commercial lease will not provide an
adequate source of repayment because of improper repair and maintenance of the
underlying security. Troy Hill ceased purchasing such participation interests in
fiscal 1992 based on an increase in delinquencies with respect to some of the
pools and because some of the participation interests in pools it had acquired
began to sustain some losses. However, in April 1996, THB began originating, to
a limited extent, commercial lease financings directly. At September 30, 1996,
$165,000 of commercial lease financings were delinquent 60 days or more.

      Loan Fee Income. In addition to interest earned on loans, Troy Hill
receives income from fees in connection with loan originations, loan
modifications, late payments, prepayments and for miscellaneous services related
to its loans. Income from these activities varies from period to period with the
volume and type of loans made and competitive conditions.

      Troy Hill charges loan origination fees which are calculated as a
percentage of the amount borrowed. Loan origination and commitment fees and all
incremental direct loan origination costs are deferred and recognized over the
contractual remaining lives of the related loans on a level yield basis.
Discounts and premiums on loans purchased are accrued and


                                      -85-
<PAGE>

amortized in the same manner. In accordance with SFAS No. 91, Troy Hill has
recognized $31,000, $141,000, $169,000 and $250,000 of amortized deferred loan
fees in income during the three months ended September 30, 1996 and the years
ended June 30, 1996, 1995 and 1994, respectively.

Asset Quality

      General. When a borrower fails to make a required payment on a loan, Troy
Hill attempts to cure the deficiency by contacting the borrower and seeking
payment. Contacts are generally made on the twentieth day after a payment is
due. In most cases, deficiencies are cured promptly. If a delinquency extends
beyond 20 days, the loan and payment history is reviewed and efforts are made to
collect the loan. While Troy Hill generally prefers to work with borrowers to
resolve such problems, when the account becomes 90 days delinquent, Troy Hill
does institute foreclosure or other proceedings, as necessary, to minimize any
potential loss.

      Loans are placed on non-accrual status when, in the judgment of
management, the probability of collection of interest is deemed to be
insufficient to warrant further accrual. When a loan is placed on non-accrual
status, previously accrued but unpaid interest is deducted from interest income.
As a matter of policy, Troy Hill does not accrue interest on loans past due 90
days or more except when the estimated value of the collateral and collection
efforts are deemed sufficient to ensure full recovery.

      Real estate acquired by Troy Hill as a result of foreclosure or by
deed-in-lieu of foreclosure are classified as real estate owned until sold.
Pursuant to a statement of position ("SOP 92-3") issued by the American
Institute of Certified Public Accountants in April 1992, which provides guidance
on determining the balance sheet treatment of foreclosed assets in annual
financial statements for periods ending on or after December 15, 1992, there is
a rebuttable presumption that foreclosed assets are held for sale and such
assets are recommended to be carried at the lower of fair value minus estimated
costs to sell the property, or cost (generally the balance of the loan on the
property at the date of acquisition). After the date of acquisition, all costs
incurred in maintaining the property are expensed and costs incurred for the
improvement or development of such property are capitalized up to the extent of
fair value. Troy Hill's accounting for its real estate owned complies with the
guidance set forth in SOP 92-3.

      During the three months ended September 30, 1996 and the years ended June
30, 1996, 1995 and 1994 approximately $6,000, $23,000, $41,000 and $54,000,
respectively, of interest would have been recorded on loans accounted for on a
non-accrual basis if such loans had been current according to the original loan
agreements for the entire period. These amounts were not included in Troy Hill's
interest income for the respective periods. The amount of interest income on
loans accounted for on a non-accrual basis and loans greater than 90 days past
due and still accruing that was included in income during the same periods
amounted to approximately $21,000, $52,000, $83,000 and $36,000, respectively.

      Classified Assets. Federal regulations require that each insured savings
association classify its assets on a regular basis. In addition, in connection
with examinations of insured institutions, federal examiners have authority to
identify problem assets and, if appropriate, classify them. There are three
classifications for problem assets: "substandard," "doubtful" and "loss."
Substandard assets have one or more defined weaknesses and are characterized by
the distinct possibility that the insured institution will sustain some loss if
the deficiencies are not corrected. Doubtful assets have the weaknesses of
substandard assets with the additional characteristic that the weaknesses make
collection or liquidation in full, on the basis of currently existing facts,
conditions, and values, questionable, and there is a high possibility of loss.
An asset classified loss is considered uncollectible and of such little value
that continuance as an asset of the institution is not warranted. Another
category designated "special mention" also must be established and maintained
for assets which do not currently expose an insured institution to a sufficient
degree of risk to warrant classification as substandard, doubtful or loss.

      At September 30, 1996, Troy Hill had $734,000 of assets classified
substandard, $225,000 of assets classified doubtful, $169,000 of assets
classified as loss and $210,000 of assets classified special mention.

      Allowance for Loan Losses. Troy Hill's policy is to establish reserves for
estimated losses on delinquent loans when it determines that losses are expected
to be incurred on such loans. The allowance for losses on loans is maintained at
a level believed adequate by management to absorb potential losses in the
portfolio. Management's determination of the adequacy of the allowance is based
on an evaluation of the portfolio, past loss experience, current economic
conditions, volume, growth and composition of the portfolio, and other relevant
factors. The allowance is increased by provisions for loan losses which are
charged against income.

      Effective December 21, 1993, the OTS, in conjunction with the Office of
the Comptroller of the Currency, the FDIC and the FRB, issued an Interagency
Policy Statement on the Allowance for Loan and Lease Losses ("Policy
Statement"). The Policy Statement, which effectively superseded the proposed
guidance issued on September 1, 1992, includes guidance (i) on the
responsibilities of management for the assessment and establishment of an
adequate allowance and (ii) for the agencies' examiners to use in evaluating the
adequacy of such allowance and the policies utilized to determine such


                                      -89-
<PAGE>

allowance. The Policy Statement also sets forth quantitative measures for the
allowance with respect to assets classified substandard and doubtful and with
respect to the remaining portion of an institution's loan portfolio.
Specifically, the Policy Statement sets forth the following quantitative
measures which examiners may use to determine the reasonableness of an
allowance: (i) 50% of the portfolio that is classified doubtful; (ii) 15% of the
portfolio that is classified substandard; and (iii) for the portions of the
portfolio that have not been classified (including loans designated special
mention), estimated credit losses over the upcoming twelve months based on facts
and circumstances available on the evaluation date. While the Policy Statement
sets forth this quantitative measure, such guidance is not intended as a "floor"
or "ceiling."

      The following table sets forth an analysis of Troy Hill's allowance for
loan and lease losses during the periods indicated.

      Management of Troy Hill believes that the reserves it has established are
adequate to cover any potential losses in THB's loan portfolio. However, future
adjustments to these reserves may be necessary, and THB's results of operations
could be adversely affected if circumstances differ substantially from the
assumptions used by management in making its determinations in this regard.

Mortgage-Backed Securities

      Troy Hill invests in a portfolio of mortgage-backed securities which are
insured or guaranteed by the FHLMC, the FNMA and/or the GNMA. To a much more
limited extent, Troy Hill also invests in collateralized mortgage obligations
("CMOs"), which are securities collateralized by FNMA and FHLMC mortgage-backed
securities. Mortgage-backed securities and CMOs increase the quality of Troy
Hill's assets by virtue of the guarantees that back them, are more liquid than
individual mortgage loans and may be used to collateralize borrowings or other
obligations of Troy Hill.

      Mortgage-backed securities typically are issued with stated principal
amounts, and the securities are backed by pools of mortgages that have loans
with interest rates that are within a range and have varying maturities. The
underlying pool of mortgages, i.e., fixed-rate or adjustable-rate, as well as
prepayment risk, are passed on to the certificate holder. The life of a
mortgage-backed pass-through security thus approximates the life of the
underlying mortgages.

      As discussed above, Troy Hill's mortgage-backed securities include CMOs,
which include securities issued by entities which have qualified under the Code
as Real Estate Mortgage Investment Conduits ("REMICs"). CMOs and REMICs
(collectively CMOs) have been developed in response to investor concerns
regarding the uncertainty of cash flows associated with the prepayment option of
the underlying mortgagor and are typically issued


                                      -91-
<PAGE>

by governmental agencies, government sponsored enterprises and special purpose
entities, such as trusts, corporations or partnerships, established by financial
institutions or other similar institutions. A CMO can be collateralized by loans
or securities which are insured or guaranteed by the FNMA, the FHLMC or the
GNMA. In contrast to pass-through mortgage-backed securities, in which cash flow
is received pro rata by all security holders, the cash flow from the mortgages
underlying a CMO is segmented and paid in accordance with a predetermined
priority to investors holding various CMO classes. By allocating the principal
and interest cash flows from the underlying collateral among the separate CMO
classes, different classes of bonds are created, each with its own stated
maturity, estimated average life, coupon rate and prepayment characteristics.

      At September 30, 1996, the carrying value of Troy Hill's mortgage-backed
securities amounted to $2.4 million, which represented 2.4% of Troy Hill's $99.5
million of total assets at that date. All of Troy Hill's $2.4 million of
mortgage-backed securities at September 30, 1996 were directly or indirectly
insured or guaranteed by federal agencies, and $1.3 million or 54.2% of the
total portfolio had fixed rates of interest and $1.1 million or 45.8% of the
total portfolio had adjustable rates of interest.

      The following table sets forth the activity in Troy Hill's mortgage-backed
securities portfolio during the periods indicated.

      As of September 30, 1996, all of Troy Hill's $2.4 million of
mortgage-backed securities with a weighted average yield of 7.98% are scheduled
to mature in over 10 years. Due to prepayments of the underlying loans, the
actual maturities of mortgage-backed securities are substantially less than the
scheduled maturities.

Sources of Funds

      General. Troy Hill's principal source of funds for use in lending and for
other general business purposes has traditionally come from deposits obtained
through Troy Hill's offices. Troy Hill also derives funds from amortization and
prepayments of outstanding loans and mortgage-backed securities, from sales of
loans, from maturing investment securities and from advances from the FHLB of
Pittsburgh. Loan repayments are a relatively stable source of funds, while
deposit inflows and outflows are significantly influenced by general interest
rates and money market conditions. Borrowings may be used on a short-term basis
to compensate for reductions in the availability of funds from other sources.
They may also be used on a longer term basis for general business purposes.

      Deposits. Troy Hill's current deposit products include passbook accounts,
negotiable order of withdrawal ("NOW") accounts, money market deposit accounts,
and certificates of deposit ranging in terms from 180 days to five years.
Included among these deposit products are $968,000 of certificates of deposit
with balances of $100,000 or more, which amounted to .02% of Troy Hill's total
deposits at September 30, 1996. Troy Hill's deposit products also include
Individual Retirement Account certificates ("IRA certificates").

      Troy Hill's deposits are obtained primarily from residents of northern
Allegheny County, Pennsylvania. Troy Hill attracts deposit accounts by offering
a wide variety of accounts, competitive interest rates, and convenient service
hours. Troy Hill utilizes traditional marketing methods to attract new customers
and savings deposits, including print media advertising and direct mailings.
Troy Hill does not advertise for deposits outside of its local market area or
utilize the services of deposit brokers, and management believes that an
insignificant number of deposit accounts were held by non-residents of
Pennsylvania at September 30, 1996.

      Troy Hill has been competitive in the types of accounts and in interest
rates it has offered on its deposit products but does not necessarily seek to
match the highest rates paid by competing institutions. With the significant
decline in interest rates paid on deposit products, Troy Hill has experienced
disintermediation of deposits into competing investment products. Troy Hill
intends to continue its efforts to attract deposits as a principal source of
funds for supporting its lending and investment activities. Although market
demand generally dictates which deposit maturities and rates will be accepted by
the public, Troy Hill intends to continue to promote longer term deposits to the
extent possible and consistent with its asset and liability management goals.

      Borrowings. Troy Hill may obtain advances from the FHLB of Pittsburgh upon
the security of the common stock it owns in that bank and certain of its
residential mortgage loans, provided certain standards related to credit
worthiness have been met. Such advances are made pursuant to several credit
programs, each of which has its own interest rate and range of maturities. Such
advances are generally available to meet seasonal and other withdrawals of
deposit accounts and to permit increased lending. At September 30, 1996, Troy
Hill had $27.0 million of advances from the FHLB of Pittsburgh.

      The following table sets forth the maximum month-end balance and average
balance of Troy Hill's FHLB advances during the periods indicated.

data processing equipment owned by THB was $42,000 at September 30, 1996.

Competition

      Troy Hill faces significant competition in attracting deposits. Its most
direct competition for deposits has historically come from commercial banks and
other savings institutions located in its market area. Troy Hill faces
additional significant competition for investors' funds from other financial
intermediaries. Troy Hill competes for deposits principally by offering
depositors a variety of deposit programs, convenient hours and other services.
Troy Hill does not rely upon any individual group or entity for a material
portion of its deposits.

      Troy Hill's competition for real estate loans comes principally from
mortgage banking companies, other savings institutions, commercial banks and
credit unions. Troy Hill competes for loan originations primarily through the
interest rates and loan fees it charges, the efficiency and quality of services
it provides borrowers, referrals from real estate brokers and builders, and the
variety of its products. Factors which affect competition include the general
and local economic conditions, current interest rate levels and volatility in
the mortgage markets. Troy Hill holds only a small portion of the large deposit
and lending market it shares with many other financial institutions, many of
whom are much larger, offer a wider array of products and services and have
substantially greater resources available as compared to Troy Hill.

      FIRREA eliminated many of the distinctions between commercial banks and
savings institutions and holding companies and allowed bank holding companies to
acquire savings institutions. FIRREA has generally resulted in an increase in
the competition encountered by savings institutions and has resulted in a
decrease in both the number of savings institutions and the aggregate size of
the savings industry.

Employees

      Troy Hill had 18 full-time employees and two part-time employees as of
September 30, 1996. None of these employees is represented by a collective
bargaining agent. Troy Hill believes that it enjoys good relations with its
personnel.

                        REGULATION AND SUPERVISION OF THB

      Set forth below is a brief description of certain laws and regulations
which relate to the regulation of THB and Troy Hill. The description of these
laws and regulations, as well as descriptions of laws and regulations contained
elsewhere herein, does not purport to be complete and is qualified in its
entirety by reference to applicable laws and regulations.

      Both PennFirst and THB are unitary savings and loan holding companies
subject to the provisions of the Home Owners' Loan Act ("HOLA") and the
regulations of the OTS. Upon consummation of the Merger, PennFirst will become a
multiple savings and loan holding company unless and until Troy Hill is merged
with and into ESBB. PennFirst does not anticipate that its status as a multiple
savings and loan holding company upon consummation of the Merger will have any
material effect upon its operations. Both Troy Hill and ESBB are federally
chartered savings institutions subject to the same regulations and OTS oversight
and supervision. The Merger will have no effect upon Troy Hill's status as a
federally chartered savings institution.

THB

      General. THB, as a savings and loan holding company within the meaning of
the HOLA, is subject to OTS regulations, examinations, supervision and reporting
requirements. As a subsidiary of a savings and loan holding company, Troy Hill
is subject to certain restrictions in its dealings with THB and affiliates
thereof.

      Activities Restrictions. There are generally no restrictions on the
activities of a savings and loan holding company which holds only one subsidiary
savings association. However, if the Director of the OTS determines that there
is reasonable cause to believe that the continuation by a savings and loan
holding company of an activity constitutes a serious risk to the financial
safety, soundness or stability of its subsidiary savings association, the
Director may impose such restrictions as deemed necessary to address such risk,
including limiting (i) payment of dividends by the savings association; (ii)
transactions


                                     -101-
<PAGE>

between the savings association and its affiliates; and (iii) any activities of
the savings association that might create a serious risk that the liabilities of
the holding company and its affiliates may be imposed on the savings
association. Notwithstanding the above rules as to permissible business
activities of unitary savings and loan holding companies, if the savings
association subsidiary of such a holding company fails to meet a qualified
thrift lender ("QTL") test, then such unitary holding company also shall become
subject to the activities restrictions applicable to multiple savings and loan
holding companies and, unless the savings association requalifies as a QTL
within one year thereafter, shall register as, and become subject to the
restrictions applicable to, a bank holding company. See "- Troy Hill - Qualified
Thrift Lender Test."

      If THB were to acquire control of another savings association, other than
through merger or other business combination with Troy Hill, THB would thereupon
become a multiple savings and loan holding company. Except where such
acquisition is pursuant to the authority to approve emergency thrift
acquisitions and where each subsidiary savings association meets the QTL test,
as set forth below, the activities of THB and any of its subsidiaries (other
than Troy Hill or other subsidiary savings associations) would thereafter be
subject to further restrictions. Among other things, no multiple savings and
loan holding company or subsidiary thereof which is not a savings association
shall commence or continue for a limited period of time after becoming a
multiple savings and loan holding company or subsidiary thereof any business
activity, upon prior notice to, and no objection by the OTS, other than: (i)
furnishing or performing management services for a subsidiary savings
association; (ii) conducting an insurance agency or escrow business; (iii)
holding, managing, or liquidating assets owned by or acquired from a subsidiary
savings association; (iv) holding or managing properties used or occupied by a
subsidiary savings association; (v) acting as trustee under deeds of trust; (vi)
those activities authorized by regulation as of March 5, 1987 to be engaged in
by multiple savings and loan holding companies; or (vii) unless the Director of
the OTS by regulation prohibits or limits such activities for savings and loan
holding companies, those activities authorized by the FRB as permissible for
bank holding companies. Those activities described in (vii) above also must be
approved by the Director of the OTS prior to being engaged in by a multiple
savings and loan holding company.

      Limitations on Transactions with Affiliates. Transactions between savings
associations and any affiliate are governed by Sections 23A and 23B of the
Federal Reserve Act. An affiliate of a savings association is any company or
entity which controls, is controlled by or is under common control with the
savings association. In a holding company context, the parent holding company of
a savings association (such as THB) and any companies which are controlled by
such parent holding company are affiliates of the savings association.
Generally, Sections 23A and 23B (i) limit the extent to which the savings
association or its subsidiaries may engage in "covered transactions" with any
one affiliate to an amount equal to 10% of such association's capital stock and
surplus, and contain an aggregate limit on all such transactions with all
affiliates to an amount equal to 20% of such capital stock and surplus and (ii)
require that all such transactions be on terms substantially the same, or at
least as favorable, to the association or subsidiary as those


                                     -102-
<PAGE>

provided to a non-affiliate. The term "covered transaction" includes the making
of loans, purchase of assets, issuance of a guarantee and similar other types of
transactions. In addition to the restrictions imposed by Sections 23A and 23B,
no savings association may (i) loan or otherwise extend credit to an affiliate,
except for any affiliate which engages only in activities which are permissible
for bank holding companies, or (ii) purchase or invest in any stocks, bonds,
debentures, notes or similar obligations of any affiliate, except for affiliates
which are subsidiaries of the savings association.

      In addition, Sections 22(h) and (g) of the Federal Reserve Act places
restrictions on loans to executive officers, directors and principal
stockholders. Under Section 22(h), loans to a director, an executive officer and
to a greater than 10% stockholder of a savings association, and certain
affiliated interests of either, may not exceed, together with all other
outstanding loans to such person and affiliated interests, the association's
loans to one borrower limit (generally equal to 15% of the institution's
unimpaired capital and surplus). Section 22(h) also requires that loans to
directors, executive officers and principal stockholders be made on terms
substantially the same as offered in comparable transactions to other persons
and also requires prior board approval for certain loans. In addition, the
aggregate amount of extensions of credit by a savings association to all
insiders cannot exceed the association's unimpaired capital and surplus.
Furthermore, Section 22(g) places additional restrictions on loans to executive
officers. At September 30, 1996, Troy Hill was in compliance with the above
restrictions.

      Restrictions on Acquisitions. Except under limited circumstances, savings
and loan holding companies are prohibited from acquiring, without prior approval
of the Director of the OTS, (i) control of any other savings association or
savings and loan holding company or substantially all the assets thereof or (ii)
more than 5% of the voting shares of a savings association or holding company
thereof which is not a subsidiary. Except with the prior approval of the
Director of the OTS, no director or officer of a savings and loan holding
company or person owning or controlling by proxy or otherwise more than 25% of
such company's stock, may acquire control of any savings association, other than
a subsidiary savings association, or of any other savings and loan holding
company.

      The Director of the OTS may only approve acquisitions resulting in the
formation of a multiple savings and loan holding company which controls savings
associations in more than one state if (i) the multiple savings and loan holding
company involved controls a savings association which operated a home or branch
office located in the state of the association to be acquired as of March 5,
1987; (ii) the acquiror is authorized to acquire control of the savings
association pursuant to the emergency acquisition provisions of the Federal
Deposit Insurance Act; or (iii) the statutes of the state in which the
association to be acquired is located specifically permit institutions to be
acquired by the state-chartered associations or savings and loan holding
companies located in the state where the acquiring entity is located (or by a
holding company that controls such state-chartered savings associations).


                                     -103-
<PAGE>

      FIRREA amended provisions of the Bank Holding Company Act of 1956 to
specifically authorize the FRB to approve an application by a bank holding
company to acquire control of a savings association. FIRREA also authorized a
bank holding company that controls a savings association to merge or consolidate
the assets and liabilities of the savings association with, or transfer assets
and liabilities to, any subsidiary bank which is a member of the Bank Insurance
Fund ("BIF") with the approval of the appropriate federal banking agency and the
FRB. As a result of these provisions, there have been a number of acquisitions
of savings associations by bank holding companies in recent years.

Troy Hill

      General. The OTS has extensive authority over the operations of savings
associations. As part of this authority, savings associations are required to
file periodic reports with the OTS and are subject to periodic examinations by
the OTS and the FDIC. The investment and lending authority of savings
associations are prescribed by federal laws and regulations and they are
prohibited from engaging in any activities not permitted by such laws and
regulations. Those laws and regulations generally are applicable to all
federally chartered savings associations and may also apply to state-chartered
savings associations. Such regulation and supervision is primarily intended for
the protection of depositors.

      FIRREA imposed limitations on the aggregate amount of loans that a savings
association could make to any one borrower, including related entities. See
"Business of Troy Hill - Lending Activities - General" for a discussion of such
limitations.

      The OTS' enforcement authority over all savings associations and their
holding companies was substantially enhanced by FIRREA. This enforcement
authority includes, among other things, the ability to assess civil money
penalties, to issue cease and desist or removal orders and to initiate
injunctive actions. In general, these enforcement actions may be initiated for
violations of laws and regulations and unsafe or unsound practices. Other
actions or inactions may provide the basis for enforcement action, including
misleading or untimely reports filed with the OTS. FIRREA significantly
increased the amount of and grounds for civil money penalties. FIRREA requires,
except under certain circumstances, public disclosure of final enforcement
actions by the OTS.

      Insurance of Accounts. The deposits of Troy Hill are insured up to
$100,000 per insured member (as defined by law and regulation) by the SAIF
administered by the FDIC and are backed by the full faith and credit of the
United States Government. As insurer, the FDIC is authorized to conduct
examinations of, and to require reporting by, FDIC-insured institutions. It also
may prohibit any FDIC-insured institution from engaging in any activity the FDIC
determines by regulation or order to pose a serious threat to the FDIC. The FDIC
also has the authority to initiate enforcement actions against savings
associations, after giving the OTS an opportunity to take such action.


                                     -104-
<PAGE>

      The FDIC may terminate the deposit insurance of any insured depository
institution, including Troy Hill, if it determines after a hearing that the
institution has engaged or is engaging in unsafe or unsound practices, is in an
unsafe or unsound condition to continue operations, or has violated any
applicable law, regulation, order or any condition imposed by an agreement with
the FDIC. It also may suspend deposit insurance temporarily during the hearing
process for the permanent termination of insurance, if the institution has no
tangible capital. If insurance of accounts is terminated, the accounts at the
institution at the time of the termination, less subsequent withdrawals, shall
continue to be insured for a period of six months to two years, as determined by
the FDIC. Management is aware of no existing circumstances which could result in
termination of Troy Hill's deposit insurance.

      The FDIC is authorized to establish separate assessment rates for deposit
insurance for members of the BIF and the SAIF. The FDIC may increase assessment
rates for either fund to restore the fund's ratio of reserves to insured
deposits to its statutorily set target level within a reasonable time, and may
decrease such assessment rates if such target level has been met. Until the SAIF
fund meets its target level, savings associations may not transfer to the BIF
fund. Furthermore, any such transfers, when permitted, would be subject to exit
and entrance fees. Under current FDIC regulations, institutions are assigned to
one of three capital groups which are based solely on the level of an
institution's capital- "well capitalized," "adequately capitalized," and
"undercapitalized" - which are defined in the same manner as the regulations
establishing the prompt corrective action system under Section 38 of the Federal
Deposit Insurance Act ("FDIA") as discussed below. These three groups are then
divided into three subgroups which reflect varying levels of supervisory
concern, from those which are considered to be healthy to those which are
considered to be of substantial supervisory concern. The matrix so created
results in nine assessment risk classifications. The insurance premiums for Troy
Hill for the first semi-annual period in calendar 1996 was .23%.

      The BIF fund met its target reserve level in September 1995, but the SAIF
was not expected to meet its target reserve level until at least 2002.
Consequently, in late 1995, the FDIC approved a final rule regarding deposit
insurance premiums which, effective with respect to the semiannual premium
assessment beginning January 1, 1996, reduced deposit insurance premiums for BIF
member institutions to zero basis points (subject to an annual minimum of
$2,000) for institutions in the lowest risk category. Deposit insurance premiums
for SAIF members were maintained at their existing levels (23 basis points for
institutions in the lowest risk category).

      On September 30, 1996, President Clinton signed into law legislation which
will eliminate the premium differential between SAIF-insured institutions and
BIF-insured institutions by recapitalizing the SAIF's reserves to the required
ratio. The legislation provides that all SAIF member institutions pay a one-time
special assessment to recapitalize the SAIF, which in the aggregate will be
sufficient to bring the reserve ratio in the SAIF to 1.25% of insured deposits.
The legislation also provides for the merger of the BIF and the SAIF, with such
merger being conditioned upon the prior elimination of the thrift charter.


                                     -105-
<PAGE>

      Effective October 8, 1996, FDIC regulations imposed a one-time special
assessment equal to 65.7 basis points for all SAIF-assessable deposits as of
March 31, 1995, which was collected on November 27, 1996. Troy Hill's one-time
special assessment amounted to $326,000. Net of related tax benefits, the
one-time special assessment amounted to $214,000. The payment of such special
assessment will have the effect of immediately reducing Troy Hill's capital by
such an amount. Nevertheless, management does not believe that this one-time
special assessment will have a material adverse effect on THB's consolidated
financial condition or cause non-compliance with Troy Hill's regulatory capital
requirements.

      On October 16, 1996, the FDIC proposed to lower assessment rates for SAIF
members to reduce the disparity in the assessment rates paid by BIF and SAIF
members. Beginning October 1, 1996, effective SAIF rates range from zero basis
points to 27 basis points. From 1997 through 1999, SAIF members will pay 6.4
basis points to fund the Financing Corporation while BIF member institutions
will pay approximately 1.3 basis points. Troy Hill's insurance premiums, which
have amounted to 23 basis points will be reduced to 6.4 basis points. Based upon
the $53.4 million of assessable deposits at September 30, 1996, Troy Hill would
expect to pay $22,000 less in insurance premiums per quarter during 1997.

      Regulatory Capital Requirements. Federally insured savings associations
are required to maintain minimum levels of regulatory capital. Pursuant to
FIRREA, the OTS has established capital standards applicable to all savings
associations. These standards generally must be as stringent as the comparable
capital requirements imposed on national banks. The OTS also is authorized to
impose capital requirements in excess of these standards on individual
associations on a case-by-case basis.

      Current OTS capital standards require savings associations to satisfy
three different capital requirements. Under these standards, savings
associations must maintain "tangible" capital equal to at least 1.5% of adjusted
total assets, "core" capital equal to at least 3% of adjusted total assets and
"total" capital (a combination of core and "supplementary" capital) equal to at
least 8.0% of "risk-weighted" assets. For purposes of the regulation, core
capital generally consists of common stockholders' equity (including retained
earnings), noncumulative perpetual preferred stock and related surplus, minority
interests in the equity accounts of fully consolidated subsidiaries, certain
nonwithdrawable accounts and pledged deposits and "qualifying supervisory
goodwill." Tangible capital is given the same definition as core capital but
does not include qualifying supervisory goodwill and is reduced by the amount of
all the savings association's intangible assets, with only a limited exception
for purchased mortgage servicing rights. Both core and tangible capital are
further reduced by an amount equal to a savings association's debt and equity
investments in subsidiaries engaged in activities not permissible to national
banks (other than subsidiaries engaged in activities undertaken as agent for
customers or in mortgage banking activities and subsidiary depository
institutions or their holding companies). A savings association is allowed to
include both core capital and supplementary capital in the calculation of its
total capital for


                                     -106-
<PAGE>

purposes of the risk-based capital requirement, provided that the amount of
supplementary capital does not exceed the savings association's core capital.
Supplementary capital generally consists of hybrid capital instruments;
perpetual preferred stock which is not eligible to be included as core capital;
subordinated debt and intermediate-term preferred stock; and, subject to
limitations, general allowances for loan losses. Assets are adjusted under the
risk-based guidelines to take into account different risk characteristics, with
the categories ranging from 0% (requiring no additional capital) for assets such
as cash to 100% for repossessed assets or loans more than 90 days past due.
Single-family residential real estate loans which are not past-due or
non-performing and which have been made in accordance with prudent underwriting
standards are assigned a 50% level in the risk-weighing system, as are certain
privately-issued mortgage-backed securities representing indirect ownership of
such loans. Off-balance sheet items also are adjusted to take into account
certain risk characteristics.

      In August 1993, the OTS adopted a final rule incorporating an
interest-rate risk component into the risk-based capital regulation. Under the
rule, an institution with a greater than "normal" level of interest rate risk
will be subject to a deduction of its interest rate risk component from total
capital for purposes of calculating its risk-based capital requirement. As a
result, such an institution will be required to maintain additional capital in
order to comply with the risk-based capital requirement. An institution with
greater than "normal" interest rate risk is defined as an institution that would
suffer a loss of net portfolio value exceeding 2.0% of the estimated market
value of its assets in the event of a 200 basis point increase or decrease (with
certain minor exceptions) in interest rates. The interest rate risk component
will be calculated, on a quarterly basis, as one-half of the difference between
an institution's measured interest rate risk and 2.0%, multiplied by the market
value of its assets. The rule also authorizes the Director of the OTS, or his
designee, to waive or defer an institution's interest rate risk component on a
case-by-case basis. The final rule was originally effective as of January 1,
1994, subject however to a three quarter "lag" time between the reporting date
of the data used to calculate an institution's interest rate risk and the
effective date of each quarter's interest rate risk component. However, in
October 1994 the Director of the OTS indicated that it would waive the capital
deductions for associations with a greater than "normal" risk until the OTS
publishes an appeals process. The OTS has recently indicated that no savings
association will be required to deduct capital for interest rate risk until
further notice.

      Effective November 28, 1994, the OTS revised its interim policy issued in
August 1993 under which savings institutions computed their regulatory capital
in accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." Under the revised OTS policy, savings institutions must
value securities available for sale at amortized cost for regulatory capital
purposes. This means that in computing regulatory capital, savings institutions
should add back any unrealized losses and deduct any unrealized gains, net of
income taxes, on debt securities reported as a separate component of GAAP
capital.

      The following table sets forth certain information concerning Troy Hill's
regulatory capital at September 30, 1996.

- ----------
(1)   Tangible and core capital are computed as a percentage of adjusted total
      assets of $95.5 million. Risk-based capital is computed as a percentage of
      total risk-weighted assets of $61.3 million.

(2)   Does not reflect the 4.0% requirement to be met in order for an
      institution to be "adequately capitalized," under applicable regulations
      as discussed below. See "- Prompt Corrective Action."

(3)   Does not reflect the interest-rate risk component to the risk-based
      capital requirement, the effective date of which has been postponed, as
      discussed above.

      Prompt Corrective Action. Under Section 38 of the FDIA, as added by the
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), each
federal banking agency is required to implement a system of prompt corrective
action for institutions which it regulates. In early September 1992, the federal
banking agencies, including the OTS, adopted substantially similar regulations
which are intended to implement Section 38 of the FDIA. These regulations became
effective December 19, 1992. Under the regulations, an institution shall be
deemed to be (i) "well capitalized" if it has total risk-based capital of 10.0%
or more, has a Tier I risk-based capital ratio of 6.0% or more, has a Tier I
leverage capital ratio of 5.0% or more and is not subject to any order or final
capital directive to meet and maintain a specific capital level for any capital
measure, (ii) "adequately capitalized" if it has a total risk-based capital
ratio of 8.0% or more, a Tier I risk-based capital ratio of 4.0% or more and a
Tier I leverage capital ratio of 4.0% or more (3.0% under certain circumstances)
and does not meet the definition of "well capitalized," (iii) "undercapitalized"
if it has a total risk-based capital ratio that is less than 8.0%, a Tier I
risk-based capital ratio that is less than 4.0% or a Tier I leverage capital
ratio that is less than 4.0% (3.0% under certain circumstances), (iv)
"significantly undercapitalized" if it has a total risk-based capital ratio that
is less than 6.0%, a Tier I risk-based capital ratio that is less than 3.0% or a
Tier I leverage capital ratio that is less than 3.0%, and (v) "critically


                                     -108-
<PAGE>

undercapitalized" if it has a ratio of tangible equity to total assets that is
equal to or less than 2.0%. Section 38 of the FDIA and the regulations
promulgated thereunder also specify circumstances under which a federal banking
agency may reclassify a well capitalized institution as adequately capitalized
and may require an adequately capitalized institution or an undercapitalized
institution to comply with supervisory actions as if it were in the next lower
category (except that the FDIC may not reclassify a significantly
undercapitalized institution as critically undercapitalized). At September 30,
1996, Troy Hill was in the "well capitalized" category.

      Safety and Soundness. FDICIA requires each federal banking regulatory
agency to prescribe, by regulation or guideline, standards for all insured
depository institutions and depository institution holding companies relating to
(i) internal controls, information systems and audit systems; (ii) loan
documentation; (iii) credit underwriting; (iv) interest rate risk exposure; (v)
asset growth; (vi) compensation, fees and benefits; and (vii) such other
operational and managerial standards as the agency determines to be appropriate.
The compensation standards would prohibit employment contracts or other
compensatory arrangements that provide excess compensation, fees or benefits or
could lead to material financial loss. In addition, each federal banking
regulatory agency must prescribe, by regulation or guideline, standards relating
to asset quality, earnings and stock valuation as the agency determines to be
appropriate. On July 10, 1995, the federal banking agencies, including the OTS,
adopted final rules and proposed guidelines concerning standards for safety and
soundness required to be prescribed by regulation pursuant to Section 39 of the
FDIA. In general, the standards relate to (1) operational and managerial
matters; (2) asset quality and earnings; and (3) compensation. The operational
and managerial standards cover (a) internal controls and information systems,
(b) internal audit system, (c) loan documentation, (d) credit underwriting, (e)
interest rate exposure, (f) asset growth, and (g) compensation, fees and
benefits. Under the proposed asset quality and earnings standards, Troy Hill
would be required to establish and maintain systems to (i) identify problem
assets and prevent deterioration in those assets, and (ii) evaluate and monitor
earnings and ensure that earnings are sufficient to maintain adequate capital
reserves. Finally, the proposed compensation standard states that compensation
will be considered excessive if it is unreasonable or disproportionate to the
services actually performed by the individual being compensated. If a savings
association fails to meet any of the standards promulgated by regulation, then
such institution will be required to submit a plan within 30 days to the OTS
specifying the steps it will take to correct the deficiency. In the event that a
savings association fails to submit or fails in any material respect to
implement a compliance plan within the time allowed by the federal banking
agency, Section 39 of the FDIA provides that the OTS must order the institution
to correct the deficiency and may (1) restrict asset growth; (2) require the
savings association to increase its ratio of tangible equity to assets; (3)
restrict the rates of interest that the savings association may pay; or (4) take
any other action that would better carry out the purpose of prompt corrective
action. Troy Hill believes that it has been and will continue to be in
compliance with each of the standards as they have been adopted by the OTS.


                                     -109-
<PAGE>

      Liquidity Requirements. All savings associations are required to maintain
an average daily balance of liquid assets equal to a certain percentage of the
sum of its average daily balance of net withdrawable deposit accounts and
borrowings payable in one year or less. The liquidity requirement may vary from
time to time (between 4% and 10%) depending upon economic conditions and savings
flows of all savings associations. At the present time, the required minimum
liquid asset ratio is 5%. Troy Hill has consistently exceeded such regulatory
liquidity requirement and, at September 30, 1996, had a liquidity ratio of
7.10%.

      Qualified Thrift Lender Test. Under Section 2303 of the Economic Growth
and regulatory Paperwork Reduction Act of 1996, a savings association can comply
with the QTL test by either meeting the QTL test set forth in the HOLA and
implementing regulations or qualifying as a domestic building and loan
association as defined in Section 7701(a)(19) of the Internal Revenue Code of
1986, as amended ("Code"). A savings association that does not comply with the
QTL Test must either convert to a bank charter or comply with the following
restrictions on its operations: (i) the association may not engage in any new
activity or make any new investment, directly or indirectly, unless such
activity or investment is permissible for a national bank; (ii) the branching
powers of the association shall be restricted to those of a national bank; (iii)
the association shall not be eligible to obtain any advances from its FHLB; and
(iv) payment of dividends by the association shall be subject to the rules
regarding payment of dividends by a national bank. Upon the expiration of three
years from the date the association ceases to be a QTL, it must cease any
activity and not retain any investment not permissible for a national bank and
immediately repay any outstanding FHLB advances (subject to safety and soundness
considerations).

      The QTL Test set forth in the HOLA requires that Qualified Thrift
Investments ("QTIs") represent 65% of portfolio assets. Portfolio assets are
defined as total assets less intangibles, property used by a savings association
in its business and liquidity investments in an amount not exceeding 20% of
assets. Generally, QTIs are residential housing related assets. The 1996
amendments allow small business loans, credit card loans, student loans and
loans for personal, family and household purposes to be included without
limitation as qualified investments. At September 30, 1996, approximately 89.18%
of Troy Hill's assets were invested in QTIs, which was in excess of the
percentage required to qualify Troy Hill under the QTL test in effect at that
time.

      Restrictions on Capital Distributions. OTS regulations govern capital
distributions by savings associations, which include cash dividends, stock
redemptions or repurchases, cash-out mergers, interest payments on certain
convertible debt and other transactions charged to the capital account of a
savings association to make capital distributions. Generally, the regulation
creates a safe harbor for specified levels of capital distributions from
associations meeting at least their minimum capital requirements, so long as
such associations notify the OTS and receive no objection to the distribution
from the OTS. Savings institutions and distributions that do not qualify for the
safe harbor are required to obtain prior OTS approval before making any capital
distributions.


                                     -110-
<PAGE>

      Generally, savings associations that before and after the proposed
distribution meet or exceed their fully phased-in capital requirements, or Tier
1 associations, may make capital distributions during any calendar year equal to
the higher of (i) 100% of net income for the calendar year-to-date plus 50% of
its "surplus capital ratio" at the beginning of the calendar year or (ii) 75% of
net income over the most recent four-quarter period. The "surplus capital ratio"
is defined to mean the percentage by which the association's ratio of total
capital to assets exceeds the ratio of its fully phased-in capital requirement
to assets. "Fully phased-in capital requirement" is defined to mean an
association's capital requirement under the statutory and regulatory standards
to be applicable on December 31, 1994, as modified to reflect any applicable
individual minimum capital requirement imposed upon the association.

      Tier 2 associations, which are associations that before and after the
proposed distribution meet or exceed their minimum capital requirements, may
make capital distributions during any calendar year up to 75% of net income over
the most recent four-quarter period.

      In order to make distributions under these safe harbors, Tier 1 and Tier 2
associations must submit written notice to the OTS 30 days prior to making the
distribution. The OTS may object to the distribution during that 30-day period
based on safety and soundness concerns. In addition, a Tier 1 association deemed
to be in need of more than normal supervision by the OTS may be downgraded to a
Tier 2 or Tier 3 association (a Tier 3 association is an association that does
not meet current minimum capital requirements or has been notified by the OTS
that it will be treated as a Tier 3 association because it is in need of more
than normal supervision and, consequently, a Tier 3 association cannot make any
capital distribution without obtaining prior OTS approval) as a result of such a
determination. Troy Hill currently is a Tier 1 institution for purposes of the
regulation dealing with capital distributions.

      On December 5, 1994, the OTS published a notice of proposed rule making to
amend its capital distribution regulation. Under the proposal, associations
would be permitted to only make capital distributions that would not result in
their capital being reduced below the level required to remain "adequately
capitalized." An association is adequately capitalized if it has a total
risk-based capital ratio of 8.0% or more, a Tier 1 risk-based capital ratio of
4.0% or more and a Tier 1 leverage capital ratio of 4.0% or more and does not
meet the definition of well capitalized. Because Troy Hill is a subsidiary of
THB, the proposal would require Troy Hill to provide notice to the OTS of its
intent to make a capital distribution. Troy Hill does not believe that the
proposal will adversely affect its ability to make capital distributions if it
is adopted substantially as proposed.

      OTS regulations also prohibit Troy Hill from declaring or paying any
dividends or from repurchasing any of its stock if, as a result, the regulatory
(or total) capital of Troy Hill would be reduced below the amount required to be
maintained for the liquidation account


                                     -111-
<PAGE>

established by it for certain depositors in connection with its conversion to
stock form ("Conversion").

      Policy Statement on Nationwide Branching. Effective May 11, 1992, the OTS
amended its policy statement on branching by federally chartered savings
associations to delete then-existing regulatory restrictions on the branching
authority of such associations and to permit nationwide branching to the extent
allowed by federal statute. (Prior OTS policy generally permitted interstate
branching for federally chartered savings associations only to the extent
allowed with respect to state-chartered savings associations in the states where
the association's home office was located and where the branch was sought or if
the branching resulted from OTS approval of a supervisory interstate acquisition
of a troubled institution.) Current OTS policy generally permits a federally
chartered savings association to establish branch offices outside of its home
state if the association meets the domestic building and loan test in Section
7701(a)(19) of the Code or the asset composition test of subparagraph (c) of
that section, and if, with respect to each state outside of its home state where
the association has established branches, the branches, taken alone, also
satisfy one of the two tax tests. An association seeking to take advantage of
this authority would have to have a branching application approved by the OTS,
which would consider the regulatory capital of the association and its record
under the Community Reinvestment Act of 1977, as amended, among other things.

      Federal Home Loan Bank System. Troy Hill is a member of the FHLB of
Pittsburgh, which is one of 12 regional FHLBs that administers the home
financing credit function of savings associations. Each FHLB serves as a reserve
or central bank for its members within its assigned region. It is funded
primarily from proceeds derived from the sale of consolidated obligations of the
FHLB System. It makes loans to members (i.e., advances) in accordance with
policies and procedures established by the Board of Directors of the FHLB.

      As a member, Troy Hill is required to purchase and maintain stock in the
FHLB of Pittsburgh in an amount equal to at least 1% of its aggregate unpaid
residential mortgage loans, home purchase contracts or similar obligations at
the beginning of each year. At September 30, 1996, Troy Hill was in compliance
with this requirement.

      As a result of FIRREA, the FHLBs are required to provide funds for the
resolution of troubled savings associations and to contribute to affordable
housing programs through direct loans or interest subsidies on advances targeted
for community investment and low-and moderate-income housing projects. These
contributions have adversely affected the level of FHLB dividends paid and could
continue to do so in the future. These contributions also could have an adverse
effect on the value of FHLB stock in the future. For the three months ended
September 30, 1996 and the years ended June 30, 1996, 1995 and 1994 dividends
paid by the FHLB of Pittsburgh to Troy Hill totalled approximately $19,000,
$32,000, $20,000 and $22,000, respectively.


                                     -112-
<PAGE>

      Federal Reserve System. The FRB requires all depository institutions to
maintain reserves against their transaction accounts (primarily NOW and Super
NOW checking accounts) and non-personal time deposits. At September 30, 1996,
Troy Hill was in compliance with applicable requirements. However, because
required reserves must be maintained in the form of vault cash or a
noninterest-bearing account at a Federal Reserve Bank, the effect of this
reserve requirement is to reduce an institution's earning assets.

Federal and State Taxation

      General. THB and Troy Hill are subject to the generally applicable
corporate tax provisions of the Code, as well as certain additional provisions
of the Code which apply to thrifts and other types of financial institutions.
The following discussion of tax matters is intended only as a summary and does
not purport to be a comprehensive description of the tax rules applicable to THB
and Troy Hill.

      Fiscal Year. THB and Troy Hill file federal income tax returns on the
basis of a June 30 fiscal year.

      Method of Accounting. Troy Hill maintains its books and records for
federal income tax purposes using the accrual method of accounting. The accrual
method of accounting generally requires that items of income be recognized when
all events have occurred that establish the right to receive the income and the
amount of income can be determined with reasonable accuracy, and that items of
expense be deducted at the later of (i) the time when all events have occurred
that establish the liability to pay the expense and the amount of such liability
can be determined with reasonable accuracy or (ii) the time when economic
performance with respect to the item of expense has occurred.

      Bad Debt Reserves. Under applicable provisions of the Code, savings
institutions such as Troy Hill are permitted to establish reserves for bad debts
and to make annual additions thereto which qualify as deductions from taxable
income. The bad debt deduction is generally based on a savings institution's
actual loss experience (the "Experience Method"). In addition, provided that
certain definitional tests relating to the composition of assets and the nature
of its business are met, a savings institution through tax years beginning in
1995 could elect annually to compute its allowable addition to its bad debt
reserves for qualifying real property loans (generally loans secured by improved
real estate) by reference to a percentage of its taxable income (the "Percentage
Method").

      Under the Experience Method, the deductible annual addition is the amount
necessary to increase the balance of the reserve at the close of the taxable
year to the greater of (i) the amount which bears the same ratio to loans
outstanding at the close of the taxable year as the total net bad debts
sustained during the current and five preceding taxable years bear to the sum of
the loans outstanding at the close of those six years or (ii) the balance in the
reserve account at the close of Troy Hill's "base year," which was its tax year
ended December 31, 1987.


                                     -113-
<PAGE>

      Under the Percentage Method, the bad debt deduction with respect to
qualifying real property loans was computed as a percentage of Troy Hill's
taxable income before such deduction, as adjusted for certain items (such as
capital gains and the dividends received deduction). Under this method, a
qualifying institution such as Troy Hill generally could deduct 8% of its
taxable income.

      The Percentage Method deduction was limited to the excess of 12% of
savings accounts at year end over the sum of surplus, undivided profits and
reserves at the beginning of the year. For taxable years ended on or before
December 31, 1993, Troy Hill generally elected to use the Percentage Method to
compute the amount of its bad debt deduction with respect to its qualifying real
property loans.

      The income of THB would not be subject to the bad debt deduction allowed
Troy Hill, whether or not consolidated tax returns are filed; however, losses of
THB or its subsidiaries included in the consolidated tax returns may reduce the
bad debt deduction allowed Troy Hill if a deduction is claimed under the
Percentage Method.

      On August 20, 1996, President Clinton signed legislation which will
eliminate the percentage of taxable income bad debt deduction for thrift
institutions for tax years beginning after December 31, 1995. The new
legislation also requires a thrift to generally recapture the excess of its
current tax reserves over its 1987 base year reserves. As THB has previously
provided deferred taxes on this amount, no additional financial statement tax
expense should result from this new legislation. The recapture amount may be
suspended for two years if Troy Hill meets certain residential lending
origination requirements.

      Distributions. If Troy Hill were to distribute cash or property to its
sole stockholder having a total fair market value in excess of its accumulated
tax-paid earnings and profits, or were to distribute cash or property to its
stockholder in redemption of its stock, Troy Hill would generally be required to
recognize as income an amount which, when reduced by the amount of federal
income tax that would be attributable to the inclusion of such amount in income,
is equal to the lesser of: (i) the amount of the distribution or (ii) the sum of
(a) the amount of the accumulated bad debt reserve of Troy Hill with respect to
qualifying real property loans (to the extent that additions to such reserve
exceed the additions that would be permitted under the experience method) and
(b) the amount of Troy Hill's supplemental bad debt reserve.

      As of September 30, 1996, Troy Hill's accumulated bad debt reserve for
qualifying real property loans and its supplemental bad debt reserve balances
were approximately $1.7 million and $300,000, respectively. Troy Hill believes
it has approximately $7.3 million of accumulated earnings and profits as of
September 30, 1996, which would be available for dividend distributions,
provided regulatory restrictions applicable to the payment of dividends are met.


                                     -114-

      Minimum Tax. The Code imposes an alternative minimum tax at a rate of 20%
on a base of regular taxable income plus certain tax preferences ("alternative
minimum taxable income" or "AMTI"). The alternative minimum tax is payable to
the extent such AMTI is in excess of an exemption amount. The Code provides that
an item of tax preference is the excess of the bad debt deduction allowable for
a taxable year pursuant to the percentage of taxable income method over the
amount allowable under the experience method. The other items of tax preference
that constitute AMTI include (a) tax exempt interest on newly-issued (generally,
issued on or after August 8, 1986) private activity bonds other than certain
qualified bonds and (b) for taxable years beginning after 1989, 75% of the
excess (if any) of (i) adjusted current earnings as defined in the Code, over
(ii) AMTI (determined without regard to this preference and prior to reduction
by net operating losses). Net operating losses can offset no more than 90% of
AMTI. Certain payments of alternative minimum tax may be used as credits against
regular tax liabilities in future years.

      Audit by IRS. Troy Hill's federal income tax returns for taxable years
through December 31, 1993 have been closed for the purpose of examination by the
Internal Revenue Service.

      State Taxation. THB is subject to the Pennsylvania Corporate Net Income
Tax and Capital Stock and Franchise Tax. The Corporate Net Income Tax rate is
currently 11.99% and is imposed on THB's unconsolidated taxable income for
federal purposes with certain adjustments. In general, the Capital Stock Tax is
a property tax imposed at the rate of 1.3% of a corporation's capital stock
value, which is determined in accordance with a fixed formula based upon average
net income and net worth.

      Troy Hill is taxed under the Pennsylvania Mutual Thrift Institutions Tax
Act (enacted on December 13, 1988 and amended in July 1989) (the "MTIT"), as
amended to include thrift institutions having capital stock. Pursuant to the
MTIT, Troy Hill's tax rate is 11.5%. The MTIT exempts Troy Hill from all other
taxes imposed by the Commonwealth of Pennsylvania for state income tax purposes
and from all local taxation imposed by political subdivisions, except taxes on
real estate and real estate transfers. The MTIT is a tax upon net earnings,
determined in accordance with GAAP with certain adjustments. The MTIT, in
computing GAAP income, allows for the deduction of interest earned on state and
federal securities, while disallowing a percentage of a thrift's interest
expense deduction in the proportion of those securities to the overall
investment portfolio. Net operating losses, if any, thereafter can be carried
forward three years for MTIT purposes.

                     DESCRIPTION OF PENNFIRST CAPITAL STOCK

General

      PennFirst's Amended and Restated Articles of Incorporation ("PennFirst's
Articles") authorize the issuance of capital stock consisting of 10,000,000
shares of PennFirst Common Stock and 5,000,000 shares of serial preferred stock,
par value $.01 per share ("PennFirst Preferred Stock"). As of the PennFirst
Record Date, there were 4,364,023 shares of PennFirst Common Stock issued and
3,901,780 shares outstanding. No shares of PennFirst Preferred Stock are
presently outstanding. The PennFirst Common Stock represents non-withdrawable
capital, is not of an insurable type and is not insured by the FDIC. Except to
the extent required by governing law, rule or regulation, the shares of capital
stock of PennFirst may be issued from time to time by the Board of Directors
without further approval of stockholders.

PennFirst Common Stock

      Each share of PennFirst Common Stock has the same relative rights as, and
is identical in all respects with, each other share of PennFirst Common Stock.
The holders of shares of PennFirst Common Stock possess all rights, including
exclusive voting rights, pertaining to the capital stock of PennFirst. Each
share of PennFirst Common Stock entitles the holder thereof to one vote on all
matters upon which stockholders have the right to vote, and stockholders of
PennFirst are not entitled to cumulate their votes for the election of
directors. The holders of PennFirst Common Stock are entitled to dividends when,
as and if declared by PennFirst's Board of Directors out of funds legally
available therefor. Holders of shares of PennFirst Common Stock are not entitled
to preemptive rights with respect to any shares which may be issued. The
PennFirst Common Stock is not subject to call or redemption.

      In the event of any liquidation or dissolution of PennFirst, the holders
of PennFirst Common Stock are entitled to receive, after payment or provision
for payment of all debts and liabilities of PennFirst, all assets of PennFirst
available for distribution, in cash or in kind. If PennFirst Preferred Stock
should be issued, the holders thereof may have a priority over the holders of
PennFirst Common Stock in the event of liquidation or dissolution.

PennFirst Preferred Stock

      The Board of Directors of PennFirst is authorized to issue PennFirst
Preferred Stock in series and fix and state voting powers, designations,
preferences or other special rights of the shares of each such series of
PennFirst Preferred Stock and the qualifications, limitations and restrictions
thereof. PennFirst Preferred Stock may rank prior to PennFirst Common Stock as
to dividend rights, liquidation preferences, or both, may have full or limited
voting rights, and may be convertible into PennFirst Common Stock. The holders
of any class or series of PennFirst Preferred Stock also may have the right to
vote separately


                                     -116-
<PAGE>

as a class or series under the terms of such class or series or as may be
otherwise provided by Pennsylvania law. PennFirst does not have any current
plans to issue any such stock.

                    COMPARISON OF THE RIGHTS OF STOCKHOLDERS

      The rights of holders of THB Common Stock are governed by the BCL and
THB's Articles of Incorporation ("THB's Articles") and Bylaws, while the rights
of holders of PennFirst Common Stock are governed by the BCL and PennFirst's
Amended and Restated Articles of Incorporation ("PennFirst's Articles") and
Bylaws. Both THB and PennFirst are Pennsylvania corporations and, as described
below, there are many similarities in the substantive provisions of the
respective articles of incorporation and bylaws of THB and PennFirst.
Accordingly, as discussed below, the rights of stockholders of THB are similar
in many respects to the rights of stockholders of PennFirst. The discussion
herein is not intended to be a complete statement of the differences affecting
the rights of THB's stockholders, but rather summarizes the more significant
differences affecting the rights of such stockholders and certain important
similarities. This summary is qualified in its entirety by reference to the BCL,
THB's Articles and Bylaws, and PennFirst's Articles and Bylaws.

Authorized Capital Stock

      THB's Articles authorize the issuance of up to 10,000,000 shares of THB
Common Stock, of which 1,124,125 shares were issued and 1,067,917 shares were
outstanding as of the THB Record Date, and up to 5,000,000 shares of serial
preferred stock, no par value per share ("THB Preferred Stock"), of which no
shares were issued and outstanding as of the THB Record Date. The THB Preferred
Stock is issuable in series, each series having such rights and preferences as
THB's Board of Directors may fix and determine by resolution.

      PennFirst's Articles authorize the issuance of up to 10,000,000 shares of
PennFirst Common Stock, of which 4,364,023 shares were issued and 3,901,780
shares were outstanding as of the PennFirst Record Date, and up to 5,000,000
shares of PennFirst Preferred Stock, of which no shares were issued and
outstanding as of the PennFirst Record Date. The PennFirst Preferred Stock is
issuable in series, each series having such rights and preferences as
PennFirst's Board of Directors may fix and determine by resolution.

Amendment of Governing Instruments

      Under the BCL, no amendment to a corporation's articles of incorporation
may be made unless it is first proposed by the board of directors, or, unless
otherwise provided in the articles, by petition of stockholders entitled to cast
at least 10% of the votes that all stockholders are entitled to cast thereon.


                                     -117-
<PAGE>

      PennFirst's Articles provide that no amendment may be made unless it is
first approved by the Board of Directors and thereafter is approved by the
holders of a majority of the shares of PennFirst Common Stock entitled to vote
generally in an election of directors, voting together as a single class, with
the exception of Article 7 (directors), Article 8 (preemptive rights), Article 9
(indemnification, etc. of officers, directors, employees and agents), Article 10
(meetings of stockholders and stockholder proposals), Article 11 (restrictions
on offers and acquisitions of PennFirst's equity securities) and Article 12
(amendment of articles and bylaws), which may not be amended without the
affirmative vote of the holders of at least 75% of the shares of PennFirst
Common Stock entitled to vote generally in an election of directors. THB's
Articles contains comparable amendment language.

      PennFirst's Bylaws may be amended by a majority vote of the Board of
Directors or by the affirmative vote of the holders of a majority of the shares
of PennFirst Common Stock entitled to vote generally in an election of
directors, voting together as a single class, with the exception of Sections 2.3
(organization and conduct of stockholders' meetings), 4.1 (number and powers of
board of directors), 4.2 (change of number of board of directors), 4.3
(vacancies in board of directors) and 4.4 (removal of directors) of the Bylaws
and Articles VIII (personal liability of directors) and XII (amendments), which
may not be amended without the affirmative vote of the holders of at least 75%
of the shares of PennFirst Common Stock entitled to vote generally in an
election of directors. THB's Articles contain comparable amendment language for
the amendment of THB's Bylaws.

Removal of Directors and Vacancies

      Under PennFirst's Articles, any director may be removed from office
without cause by an affirmative vote of not less than 75% of the total votes
eligible to be cast by stockholders at a duly constituted meeting of
stockholders called expressly for such purpose and may be removed from office
with cause by an affirmative vote of not less than a majority of the total votes
eligible to be cast by stockholders. In addition, under PennFirst's Articles,
vacancies in PennFirst's Board of Directors, including vacancies created by
newly created directorships resulting from an increase in the number of
directors, may be filled by PennFirst's Board of Directors, acting by a vote of
a majority of the directors then in office, even if less than a quorum, and any
director so chosen shall serve for the remainder of the term of the class of
directors in which the vacancy occurred and until his successor is elected and
qualified. THB's Articles contains comparable language to remove directors and
fill vacancies.

Director Indemnification and Liability

      PennFirst's Articles and Bylaws provide that a director of PennFirst will
not be personally liable for monetary damages for actions taken, or any failure
to take any action, as a director except to the extent that by law a director's
liability for monetary damages may not be limited. This provision, which is
permitted under the Pennsylvania Directors'


                                     -118-
<PAGE>

Liability Act, does not limit the personal liability of the directors of
PennFirst for monetary damages for breaches of the standard of care imposed on
directors as fiduciaries which constitute self-dealing, willful misconduct or
recklessness. In addition, this provision does not limit the liability of
directors arising under any criminal statute or for the payment of any federal,
state or local taxes. This provision applies to actions taken by a director only
in that capacity; it does not apply to actions taken in any other capacity,
including that of an officer. PennFirst's Articles and Bylaws also provide that
any amendment or repeal of this provision will not adversely affect any right of
a director of PennFirst with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.

      PennFirst's Articles provide that PennFirst shall indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative, because such person is or was a director, officer, employee or
agent of PennFirst. Indemnification will be furnished to the full extent
provided by law against expenses (including attorneys' fees), judgments, fines,
excise taxes and amounts paid in settlement actually and reasonably incurred in
connection with such action, suit or proceeding. In particular, indemnification
will be made against judgments and settlements in derivative suits.
Indemnification will be made unless a judgment or other final adjudication
establishes that the act or failure to act giving rise to the claim for
indemnification constituted willful misconduct or recklessness. The
indemnification provisions also permit PennFirst to pay reasonable expenses in
advance of the final disposition of any action, suit or proceeding as authorized
by PennFirst's Board of Directors, provided that the indemnified person
undertakes to repay PennFirst if it is ultimately determined that such person
was not entitled to indemnification.

      The rights of indemnification provided in PennFirst's Articles are not
exclusive of any other rights which may be available under PennFirst's Bylaws,
any insurance or other agreement, by vote of stockholders or disinterested
directors or otherwise. In addition, PennFirst's Articles authorize PennFirst to
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of PennFirst, whether or not PennFirst would have the power to
provide indemnification to such person. By action of the Board of Directors,
PennFirst may create and fund a trust fund or fund of any nature, and may enter
into agreements with its officers and directors, for securing or insuring in any
manner its obligation to indemnify or advance expenses provided for in the
provisions in PennFirst's Articles and Bylaws regarding indemnification.

      THB's Articles and Bylaws also contain the aforementioned director
indemnification and liability provisions.

Special Meetings of Stockholders

      Pursuant to PennFirst's Articles and THB's Articles, special meetings of
stockholders may be called by the Chairman of the Board, the President or by a
majority of the Board of Directors.


                                     -119-
<PAGE>

Actions by Stockholders Without a Meeting

      PennFirst's Articles and THB's Articles provide that any action required
to be taken or which may be taken at any annual or special meeting of
stockholders may be taken without a meeting if a consent in writing, setting
forth the action so taken, is given by the holders of all outstanding shares
entitled to vote thereon.

Stockholder Nominations and Proposals

      PennFirst's Articles provide that all nominations for election to the
Board of Directors, other than those made by the Board or a committee thereof,
be made by a stockholder who has complied with the notice provisions in
PennFirst's Articles. Written notice of a stockholder nomination must be
communicated to the attention of the Secretary of PennFirst and either delivered
to, or mailed and received at, the principal executive offices of PennFirst not
less than 60 days prior to the anniversary date of the immediately preceding
annual meeting of stockholders of PennFirst. Each such notice shall set forth
the information required by Article 7.F of PennFirst's Articles.

      PennFirst's Articles also provide that only such business as shall have
been properly brought before an annual meeting of stockholders shall be
conducted at the annual meeting. For business to be properly brought before an
annual meeting, such business must be (a) brought before the meeting by or at
the direction of the Board of Directors or (b) otherwise properly brought before
the meeting by a stockholder who has given timely notice thereof in writing to
the Secretary of PennFirst. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive office of
PennFirst not less than 60 days prior to the anniversary date of the immediately
preceding annual meeting. A stockholder's notice to the Secretary shall set
forth as to each matter the stockholder proposes to bring before the annual
meeting the information required by Article 10.F of PennFirst's Articles. The
presiding officer of an annual meeting shall determine and declare to the
meeting whether the business was properly brought before the meeting in
accordance with the provisions of the PennFirst Articles, and any such business
not properly brought before the annual meeting shall not be transacted. THB's
Articles contain comparable language on stockholder nominations and proposals.

Provisions Affecting Business Combinations and Control Share Acquisitions

      The BCL contains four "anti-takeover" sections that apply to registered
corporations relating to control share acquisitions, the disgorgement of profits
by certain controlling persons, business combination transactions with
interested stockholders and the ability of stockholders to put their stock
following a control transaction. A corporation that was a registered corporation
on April 27, 1990 could opt-out of the "control share acquisition" or
"disgorgement of profits" provisions by an explicit amendment of its bylaws
adopted by its board of directors on or before July 26, 1990. A corporation that
became a registered corporation after April 27, 1990 could opt out by an
explicit provision in its original articles


                                     -120-
<PAGE>

of incorporation or by an explicit amendment to its articles of incorporation
adopted on or before 90 days after the corporation first becomes a registered
corporation. PennFirst has opted out of the "control share acquisitions" section
of the BCL, while THB not has opted out of any of the four "anti-takeover"
sections.

      The disgorgement of profits section of the BCL generally provides that a
corporation will be entitled to recover any "profit" realized by a "controlling
person or group" from the disposition of any equity security of the corporation
that occurs within 18 months after the date when that person or group became a
controlling person or group, if the equity security was acquired within 24
months before or 18 months after such date. Generally, a "controlling person or
group" for such purposes is any person or group who has (i) acquired, offered to
acquire or, directly or indirectly, publicly disclosed or caused to be disclosed
the intention of acquiring voting power over voting shares that would entitle
the holder thereof to cast at least 20% of the votes that all stockholders would
be entitled to cast in an election of directors or (ii) directly or indirectly,
publicly disclosed or caused to be disclosed that it may wish to acquire control
of a corporation through any means.

      The business combination transaction with an interested stockholder
section of the BCL provides that certain transactions with an "interested
stockholder," including mergers, consolidations, share exchanges and sales of
assets, must be approved by the holders of a majority of the disinterested
shares in addition to any other approvals that may be required. This requirement
does not apply if the transaction is approved by a disinterested majority of the
board of directors or if the consideration paid to the other stockholders in the
transaction is not less than the highest amount paid by the interested
stockholder in acquiring shares. An "interested stockholder" includes any
stockholder who is a party to the transaction or who is treated differently from
the other stockholders and affiliates of the interested stockholder.

      Under the provision of the BCL that permits stockholders to put their
shares, stockholders of a registered corporation that becomes subject to a
"control transaction" can demand from the controlling person or group payment in
cash for his or her shares an amount equal to the fair value of his or her
shares on the date that the "control transaction" occurred. A "control
transaction" for such purposes is the acquisition of 20% or more of a
corporation's voting shares by a person or group, with several exceptions.

Acquisition of Capital Stock

      THB's Articles and PennFirst's Articles both provide that until five years
from the completion of the conversion of the respective savings bank from mutual
to stock form, June 24, 1999 and June 13, 1995, respectively, no person shall
directly or indirectly offer to acquire or acquire the beneficial ownership of
more than 10% of the issued and outstanding shares of any class of an equity
security of THB or PennFirst, respectively. With respect to THB, the foregoing
restrictions do not apply to, among other things, any offer or acquisition
approved in advance by the affirmative vote of two-thirds of THB's Board of
Directors. The


                                     -121-
<PAGE>

proposed Merger was approved in advance by the affirmative vote of more than
two-thirds of THB's Board and, accordingly, is not subject to the foregoing
restrictions.

                              STOCKHOLDER PROPOSALS

PennFirst

      Any proposal which a stockholder wished to have included in the proxy
solicitation materials to be used in connection with the next Annual Meeting of
Stockholders of PennFirst, must have been received at the principal executive
offices of PennFirst, 600 Lawrence Avenue, Ellwood City, Pennsylvania 16117,
Attention: Secretary, no later than Tuesday, October 22, 1996. No proposals were
received by such date.

      Stockholder proposals which are not submitted for inclusion in PennFirst's
proxy materials pursuant to Rule 14a-8 under the Exchange Act may be brought
before an annual meeting pursuant to Article 10.F of PennFirst's Articles as
described above. See "Comparison of the Rights of Stockholders - Stockholder
Nominations and Proposals."

THB

      If the Merger is not consummated prior to THB's annual meeting of
stockholders, any proposal which a stockholder wished to have included in THB's
proxy statement and form of proxy relating to THB's 1997 Annual Meeting of
Stockholders must have been received by THB at 1706 Lowrie Street, Pittsburgh,
Pennsylvania 15212 by June 2, 1997.

                                 LEGAL OPINIONS

      The legality of the shares of PennFirst Common Stock to be issued in the
Merger, certain federal income tax consequences of the Merger, and certain other
legal matters relating to the Merger are being passed upon by Elias, Matz,
Tiernan & Herrick L.L.P., Washington, D.C., special counsel to PennFirst.

                                     EXPERTS

      The consolidated financial statements of PennFirst as of December 31, 1995
and 1994, and for each of the years in the three-year period ended December 31,
1995, have been incorporated by reference in this Joint Proxy
Statement/Prospectus in reliance upon the report of KPMG Peat Marwick LLP,
independent certified public accountants, incorporated by reference, and upon

for income taxes in 1993 and to a change in accounting for certain debt and
equity securities during 1994.

      The consolidated financial statements of THB as of June 30, 1996, and for
the year ended June 30, 1996, have been included in this Joint Proxy

LLP, independent certified public accountants, as indicated in their report with
respect thereto, and are incorporated herein by reference in reliance upon the

      On April 10, 1996, the Board of Directors of THB terminated the services
of Grant Thornton LLP as THB's independent auditors. For the fiscal years ended
June 30, 1995 and 1994 and up to the date of the discontinuation of services of
Grant Thornton LLP, there were no disagreements with Grant Thornton LLP, on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedure which, if not resolved to the satisfaction of Grant
Thornton LLP, would have caused it to make a reference to the subject matter of
the disagreement in connection with its reports.

                             Independent Auditors' Report
                                           



The Board of Directors
Troy Hill Bancorp, Inc.:


We have audited the accompanying consolidated statement of financial condition
of Troy Hill Bancorp, Inc. and subsidiary (the Company) as of June 30, 1996, and
the related consolidated statement of earnings, stockholders' equity and cash
flows for the year then ended.  These consolidated financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these consolidated financial statements based on our audit.  The
accompanying financial statements of the Company as of June 30, 1995, and for
each of the years in the two-year period then ended were audited by other
auditors whose report thereon dated August 11, 1995, expressed an unqualified
opinion with an explanatory paragraph for changes in accounting for investment
securities in 1995 and income taxes in 1994 on those statements.

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

In our opinion, the 1996 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Troy Hill
Bancorp, Inc. and subsidiary as of June 30, 1996, and the results of its
operations and its cash flows for the year then ended in conformity with
generally accepted accounting principles.

                  REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



Board of Directors and Stockholders
Troy Hill Bancorp, Inc.


          We have audited the accompanying consolidated statements of financial
condition of Troy Hill Bancorp, Inc. and subsidiary as of June 30, 1995 and the
related statements of earnings, stockholders' equity and cash flows for each of
the two years in the period ended June 30, 1995. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

          In our opinion, the financial statements referred to above present 
fairly, in all material respects, the consolidated financial position of Troy 
Hill Bancorp, Inc. and subsidiary as of June 30, 1995 and the consolidated 
results of their operations and cash flows for each of the two years in the 
period ended June 30, 1995, in conformity with generally accepted accounting 
principles.

          As discussed in the notes to the consolidated financial 
statements, the Company changed its method of accounting for investment 
securities in 1995 and income taxes in 1994.

(1)       Summary of Accounting Policies

          Troy Hill Bancorp, Inc. and subsidiary (the Company) is primarily 
             engaged in the business of attracting retail deposits from the 
             general public and using such funds to invest primarily in 
             residential and commercial mortgage loans.  The Company is 
             subject to competition from other financial institutions.  The 
             Company is also subject to the regulations of certain federal 
             agencies and undergoes periodic examinations by those regulatory 
             authorities.

          The following comprise the significant accounting policies which the
             Company follows in preparing and presenting their consolidated
             financial statements:

          Conversion to Stock Form

          On June 24, 1994, Troy Hill Federal Savings and Loan Association 
             (the Association) completed its conversion from a federally 
             chartered, mutual savings and loan association to a federally 
             chartered, stock savings bank known as Troy Hill Federal Savings 
             Bank (Troy Hill), followed by the issuance of all of Troy Hill's 
             outstanding common shares to the Company, a newly formed holding 
             company.  The financial statements for the periods prior to 
             June 24, 1994, are those of the Association prior to the 
             conversion and reorganization.

          Principles of Consolidation

          The accompanying consolidated financial statements include the 
             accounts of the Company and its wholly owned subsidiary, Troy 
             Hill.  All significant intercompany transactions have been 
             eliminated. 

          Basis of Presentation

          The financial statements have been prepared in conformity with 
             generally accepted accounting principles.  In preparing the 
             financial statements, management is required to make estimates 
             and assumptions that affect the reported amounts of assets and 
             liabilities as of the date of the statement of financial 
             condition and revenues and expenses for the period.  Actual 
             results could differ significantly from those estimates.  The 
             unaudited interim financial statements for the three months ended 
             September 30, 1996 and 1995, reflect all adjustments (consisting 
             of only normal recurring accruals except for the item noted in 
             note 5 relating to the SAIF insurance assessment) which, in the 
             opinion of management are necessary to present fairly the 
             results for interim periods.  Results of the interim periods are 
             not necessarily indicative of results to be expected for the 
             full year.

          Loans Held for Sale

          Mortgage loans originated and intended for sale are carried at lower 
             of cost or market value determined in the aggregate.

                                                                    
                                                                  (Continued)

          Investment and Mortgage-Backed Securities Available for Sale

          On July 1, 1994, the Company adopted Statement of Financial 
             Accounting Standards No. 115 (SFAS 115), "Accounting for Certain 
             Investments in Debt and Equity Securities."  SFAS 115 addresses 
             the accounting and reporting for investments in equity 
             securities that have readily determinable fair values and all 
             investments in debt securities.  Those investments are 
             classified in three categories and accounted for based on the 
             respective classification.  Debt securities that the Company has 
             the positive intent and ability to hold to maturity are 
             classified as held to maturity and reported at amortized cost.  
             Debt and equity securities that are bought and held principally 
             for the purpose of selling them in the near term are classified 
             as trading securities and reported at fair value, with 
             unrealized gains and losses included currently in income.  Debt 
             and equity securities classified as neither held to maturity or 
             trading securities are classified as available for sale and 
             reported at fair value, with unrealized gains and losses 
             excluded from income and reported as a separate component of 
             stockholders' equity, net of income taxes.  The Company did not 
             classify any debt or equity securities as trading securities in 
             1996 or 1995.  In periods prior to July 1, 1994, investments 
             securities and mortgage-backed securities were stated at cost, 
             adjusted for amortization of premiums and accretion of discounts 
             using the level yield method.

          Gains and losses on sales of securities are recognized using the 
             specific identification method.  Purchases and sales of securities 
             are accounted for on a settlement date basis which is not 
             materially different than use of the trade date basis.

          Loans Receivables

          Loans receivable are carried at unpaid principal balances, less the
             allowance for loan losses and net deferred loan origination 
             fees. Interest on loans is credited to income as earned.  
             Interest earned on loans for which no payments were received 
             during the month is accrued.  Uncollectible interest on loans 
             that are contractually past due is charged off or an allowance 
             is established based on management's periodic evaluation.  The 
             allowance is established by a charge to interest income equal to 
             all interest previously accrued.  Income is subsequently 
             recognized only to the extent cash payments are received until, 
             in management's judgment, the borrower's ability to make 
             periodic interest and principal payments is re-established, in 
             which case the loan is returned to accrual status.  If the 
             collection of principal is in doubt in whole or in part, all 
             payments received on nonaccrual loans are credited to principal 
             until such doubt is eliminated.  Monthly mortgage loan payments 
             are adjusted annually to cover insurance and tax requirements.

          Loan origination fees received, net of certain direct origination 
             costs are deferred on a loan-by-loan basis and amortized to 
             interest income using a method which approximates the interest 
             method, giving effect to actual loan prepayments.

                                                                  (Continued)

                           (Dollar Amounts in Thousands)
                                          


          On July 1, 1995, the Company adopted SFAS No. 114, "Accounting by
             Creditors for Impairment of a Loan," and SFAS No. 118, 
             "Accounting by Creditors for Impairment of a Loan - Income 
             Recognition and Disclosures," which provide guidelines for 
             measuring and reporting impairment losses on loans.  A loan is 
             considered to be impaired when it is probable that the Company 
             will be unable to collect all principal and interest amounts due 
             according to the contractual terms of the loan agreement.  All 
             nonperforming loans, excluding consumer, lease and certain 
             single-family loans, are considered to be impaired loans. 
             Impaired loans are required to be measured based upon the 
             present value of expected future cash flows, discounted at the 
             loan's initial effective interest rate, or at the loan's market 
             price or fair value of the collateral if the loan is collateral 
             dependent.  If the loan valuation is less than the recorded 
             value of the loan, an impairment reserve must be established for 
             the difference by either an allocation of the allowance for loan 
             losses or by a provision for loan losses, depending on the 
             adequacy of the allowance for loan losses.  Impaired loans at 
             September 30, 1996, were $184 (unaudited) and $105 at June 30, 
             1996, that had a related impairment reserve of $28 (unaudited) 
             and $16 at June 30, 1996.  Average impaired loans during the 
             year ended June 30, 1996, were $269 ($131 (unaudited) for the 
             three months ended September 30, 1996).  During the year 1996, 
             the Company recognized $15 of interest revenue on impaired 
             loans, ($2 (unaudited) for the three months ended September 30, 
             1996) all of which was recognized using the cash basis method of 
             income recognition.

          Provision for Loan Losses

          Provisions for estimated losses on loans are charged to earnings in 
             an amount that results in an allowance for loan losses sufficient,
             in management's judgment, to cover anticipated losses based on 
             management's periodic evaluation of known and inherent risks in 
             the loan portfolio, past and expected future loss experience of 
             the Company, current economic conditions, adverse situations 
             which may affect a specific borrower's ability to repay, the 
             estimated value of any underlying collateral and other relevant 
             factors.

          Material estimates that are particularly susceptible to significant 
             change in the near-term relate to the determination of the 
             allowance for loan losses.  Management believes that the  
             allowance for loan losses is adequate. While  management uses 
             available information to recognize losses on loans, future 
             additions to the allowance may be necessary based on changes in 
             economic conditions.  In addition, various regulatory agencies, 
             as an integral part of their examination process, periodically 
             review the Company's allowance for loan losses.  Such agencies 
             can require the Company to adjust the allowance based on their 
             judgments about information available to them at the time of 
             their examination.

                                                                    
                                                                    
                                                                  (Continued)

          Real Estate Owned

          Real estate owned (properties acquired by foreclosure or voluntarily
             conveyed by delinquent borrowers in lieu of foreclosure) are 
             recorded as of the acquisition date at the lower of cost or fair 
             value less estimated costs to sell as established by a current 
             appraisal.  Costs relating to development and improvement of the 
             property are capitalized, whereas costs relating to the holding 
             of such real estate are expensed as incurred.  Subsequent to 
             acquisition, valuations are periodically performed by 
             management; and the carrying value of the real estate acquired 
             is subsequently adjusted by establishing a valuation allowance 
             and recording a charge to operations if the carrying value of a 
             property exceeds its estimated fair value less estimated costs 
             to sell.  Gains and losses from the sale of real estate are 
             recognized upon sale and are based upon the net carrying value 
             of the related property.

          Premises and Equipment

          Premises and equipment are stated at cost less accumulated 
             depreciation. Depreciation for financial reporting purposes is 
             computed using the straight-line method over the estimated 
             useful lives of the related assets of five to forty years.  
             Accelerated methods are used for income tax purposes.

          Interest on Savings Deposits

          Interest on savings deposits is accrued and charged to expense 
             monthly and is paid or credited in accordance with the terms of 
             the respective accounts.

          Income Taxes

          Deferred taxes are provided for under the asset and liability method
             of accounting for income taxes.  Under the asset and liability 
             method, deferred tax assets and liabilities are recognized for 
             the future tax consequences attributable to differences between 
             the financial statement carrying amounts of existing assets and 
             liabilities and their respective tax bases.  Deferred tax assets 
             and liabilities are measured using enacted tax rates expected to 
             apply to taxable income in the years in which those temporary 
             differences are expected to be recovered or settled.  The effect 
             on deferred tax assets and liabilities of a change in tax rates 
             is recognized in income in the period that includes the 
             enactment date.

                                                                    
                                                                  (Continued)

          Cash Equivalents

          For purposes of reporting cash flows, cash and cash equivalents 
             consists of cash and due from banks.

          Earnings Per Share

          Earnings per share (EPS) is computed by dividing net income by the
             weighted average number of common shares and common stock 
             equivalents outstanding during the period.  Such shares amounted 
             to 1,005,655 (unaudited) for the three months ended September 
             30, 1996, and 995,480 and 1,035,235 for the years ended June 30, 
             1996 and 1995.  Shares outstanding for 1996 and 1995, do not 
             include ESOP shares that were purchased and unallocated during 
             1996 and 1995 in accordance with SOP 93-6, "Employers' 
             Accounting for Employee Stock Ownership Plans." Shares granted 
             but not yet issued under the Company's stock option plan are 
             considered common stock equivalents for earnings per share 
             calculations.

          For fiscal year ended June 30, 1994, the provisions of Accounting
             Principles Board Opinion No. 15, "Earnings Per Share," are not 
             applicable as the Company converted to the stock form of 
             ownership in June 1994.

          Reclassifications

          Certain items previously reported have been reclassified to conform 
             to the current year's reporting format.

                           (Dollar Amounts in Thousands)

          Sale of investment and mortgage-backed securities available for sale
             during the three months ended September 30, 1996, and the years 
             ended June 30, 1996 and 1995, resulted in proceeds of $2,548 
             (unaudited), $6,691 and $5,662, respectively.  Gross realized 
             gains of $25 (unaudited), $17 and $60 and gross realized losses 
             of $19 (unaudited), $22 and $96, respectively, were recorded.  
             There were no sales of securities during the three months ended 
             September 30, 1996, and the year ended June 30, 1994.

          Accrued income receivable on securities available for sale and held 
             to maturity was approximately $31 (unaudited), $108 and $166 at 
             September 30, 1996, and June 30, 1996 and 1995, respectively.

          In November 1995, the Financial Accounting Standards Board (FASB) 
              issued "A Guide to Implementation of Statement 115 on 
             Accounting for Certain Investments in Debt and Equity 
             Securities, Questions and Answers." This guide permitted a 
             one-time reassessment of the appropriateness of the 
             classifications of securities as available for sale or held for 
             investment.  The Company transferred approximately $6,900 of 
             investment securities with a market value of $6,800 from the 
             held to maturity category to the securities available for sale 
             category.  Concurrent with this redesignation, all but 
             approximately $1,700 of the securities transferred were sold at 
             a realized loss of $5.

          The amortized cost, gross unrealized gains, gross unrealized losses 
             and approximate market value of investment and mortgage-backed 
             securities held to maturity were as follows:

          The Company's lending efforts have historically focused on one- to  
             four-family residential and construction real estate loans, 
             primarily in the western Pennsylvania area.  Generally, such 
             loans have been underwritten on the basis of 80% loan to value 
             ratio or mortgage insurance was required.  The Company, as with 
             any lending institution, is subject to the risk that real estate 
             values could deteriorate in its primary lending area thereby 
             impairing collateral values.  Management believes, however, that 
             real estate values in the Company's primary lending area are 
             currently stable.

(5)       Commitments and Contingencies

          The Company is a party to financial instruments with 
             off-balance-sheet risk in the normal course of business to meet 
             the financing needs of its customers.  These financial 
             instruments include commitments to extend credit through loans 
             approved, but not yet funded, and lines of credit.  The Company 
             uses the same credit policy in making commitments and 
             conditional obligations as it does for on-balance sheet 
             instruments.  The Company evaluates each customer's 
             credit-worthiness on an individual basis, and the amount of 
             collateral is based upon the credit evaluation.  The commitments 
             to extend credit generally have fixed expiration dates or other 
             termination clauses and may require payment of a fee.  As some 
             of the commitments may not be utilized, or utilized in amounts 
             less than the total committed, the total commitment amounts do 
             not necessarily represent future cash requirements.  As of 
             September 30, 1996, and June 30, 1996, the Company had 
             outstanding commitments to originate and fund first mortgage and 
             construction loans of $3,814 (unaudited) and $3,407, 
             respectively, of which $131 (unaudited) and $407 were at 
             variable rates.  Unused lines of credit approximated $2,692 
             (unaudited) at September 30, 1996, and $7,750 at June 30, 1996.

          At June 30, 1996 and 1995, the Company had not entered into any 
             derivative instruments with significant off-balance-sheet risk, 
             such as futures, swaps, options or similar investments.

          The undercapitalized status of the FDIC's Savings Association 
             Insurance Fund resulted in the introduction of federal 
             legislation to recapitalize the SAIF which would require thrifts 
             like Troy Hill Bancorp, Inc. to pay a one-time charge based on 
             deposits to recapitalize the depleted insurance fund.  The 
             legislation became law on September 30, 1996, and resulted in a 
             charge of $326 (unaudited), $215 (unaudited) net of taxes for 
             the three-month period ended September 30, 1996.  Payment of the 
             assessment is due in November 1996.

          The Company has not established a valuation allowance as it is 
             management's belief that it has adequate current taxable income 
             and carrybacks to realize the net deferred income tax assets.

          Under certain provisions of the Internal Revenue code (the Code), 
           qualified thrift institutions were permitted to deduct from 
           taxable income a provision for bad debts based on either actual 
           bad debt experience or a percentage of taxable income before 
           such deduction. The deduction percentage, subject to certain 
           minimum tax provisions and other limitations, was 8%.

          On August 20, 1996, President Clinton signed legislation which will 
             eliminate the percentage of taxable income bad debt deduction 
             for thrift institutions for tax years beginning after 
             December 31, 1995.  This new legislation also requires a thrift 
             to generally recapture the excess of its current tax reserves 
             over its 1987 base year reserves.  As the Company has previously 
             provided deferred taxes on this amount, no additional financial 
             statement tax expense should result from this new legislation.

                                                                  (Continued)

                      (Dollar Amounts in Thousands) 

          The Company and its subsidiaries file a consolidated federal income 
             tax return on a June 30 fiscal year end basis.  The Company is 
             permitted under the code to deduct an annual addition to a 
             reserve for bad debts in determining taxable income, subject to 
             certain limitations.  Bad debt deductions for income tax 
             purposes are included in taxable income of later years only if 
             the bad debt reserve is used subsequently for purposes other 
             than to absorb bad debt losses.  Because the Company does not 
             intend to use the reserve for purpose other than to absorb 
             losses, no deferred income taxes have been provided prior to 
             1987.  Retained earnings at September 30, 1996, includes 
             approximately $1.8 million (unaudited) representing such bad 
             debt deductions for which no deferred income taxes have been 
             provided.

(11)      Employee Benefit Plans

          The Company maintains a defined benefit pension plan covering 
             substantially all of its employees.  The Company makes 
             contributions to the plan equal to the amount that is tax 
             deductible under the Internal Revenue Code.  Plan assets 
             consist primarily of certificates of deposit issued by 
             Troy Hill.

          Pension cost is comprised of the following components:

          The following sets forth the plan's funded status and the amounts 
             recognized in the Company's consolidated statements of financial 
             condition at June 30, 1996 and 1995.  The plans funding status 
             and related actuarial information is not available as of 
             September 30, 1996.  Management believes plan conditions did not 
             materially change during the interim period.

          In conjunction with the conversion to the stock form of ownership, 
             the Company implemented a tax qualified Employee Stock Ownership 
             Plan (ESOP).  The ESOP provides retirement benefits for 
             substantially all full-time employees who have completed one 
             year of service.  The ESOP acquired 89,930 shares of the 
             Company's common stock at a cost of $944, which was financed 
             through a loan with the Company.  The loan obligation of the 
             ESOP is considered deferred compensation and, accordingly, has 
             been recorded as a reduction of stockholders' equity.  The loan 
             from the Company will be repaid over a ten-year period from 
             contributions to the ESOP by the Company.  The shares acquired by 
             the ESOP are held in a suspense account and are released to the 
             ESOP for allocation to the various plan participants as the loan 
             is reduced.  There were approximately 2,500 (unaudited), 10,576 
             and 11,096 shares committed to be released to the ESOP at 
             September 30, 1996, and June 30, 1996 and 1995, respectively. 
             Unallocated ESOP shares at September 30, 1996, amounted to 
             68,258 shares with a total fair value of approximately $1,350 
             (unaudited).

                                                                  (Continued)

                      (Dollar Amounts in Thousands) 

          The Company accounts for the ESOP in accordance with Statement of   
             Position 93-6, "Employers' Accounting for Employee Stock 
             Ownership Plans."  As shares are committed to be released, the 
             Company reports compensation expense equal to the current market 
             price of the shares and the shares become outstanding for EPS 
             computations.  Dividends on unallocated ESOP shares are recorded 
             as a reduction of debt and accrued interest.

          Compensation expense for the ESOP was approximately $150 and $123 
             for the years ended June 30, 1996 and 1995, respectively, and 
             $42 (unaudited) for the three months ended September 30, 1996.

          In connection with the conversion to the stock form of ownership, 
             the Company has adopted a Recognition and Retention Plan and 
             Trust (RRP).  The RRP has acquired 44,965 shares of the 
             Company's common stock.  Shares of the common stock granted to 
             officers and directors generally vest over a five-year period 
             and are restricted until vested.  The Company has granted, under 
             the RRP, 32,597 shares during the year ended June 30, 1995.  No 
             shares were awarded in 1996 or for the three months ended 
             September 30, 1996.  The Company accrues compensation expense for 
             the shares granted over the respective vesting periods. 
             Compensation expense for the RRP for the three months ended 
             September 30, 1996, and the years ended June 30, 1996 and 1995, 
             amounted to approximately $22 (unaudited), $80 and $56, 
             respectively.

          The Company has implemented stock option plans for officers, 
             directors and key employees.  A total of 112,412 shares of the 
             Company's common stock has been reserved for future issuance.  
             Options granted may be incentive or nonqualified, and such 
             options vest over periods ranging between six months (for 
             options granted to nonemployee directors) to five years (for 
             employees of the Company) and expire ten years after issuance.  
             Options to purchase 25,290 shares and 44,963 shares were granted 
             in fiscal 1995 at a price of $11.13 to nonemployee directors and 
             certain employees, respectively.  Options to purchase 2,808 
             shares were granted to nonemployee directors in fiscal 1996.  At 
             September 30, 1996, 37,094 options were exercisable.  No options 
             have been exercised.  There were no options granted for the 
             three-month period ended September 30, 1996.

                                                                  (Continued)

(13)      Regulatory Capital

          Troy Hill is subject to various regulatory capital 
             requirements administered by the federal baking agencies.  
             Failure to meet minimum capital requirements can initiate 
             certain mandatory - and, possibly additional discretionary - 
             actions by regulators that, if undertaken, could have a direct 
             material effect on Troy Hill's financial statements.  Under 
             capital adequacy guidelines and the regulatory framework for 
             prompt corrective action, Troy Hill must meet specific capital 
             guidelines that involve quantitative measures of Troy Hill's 
             assets, liabilities and certain off-balance-sheet items as 
             calculated under regulatory accounting practices.  Troy Hill's 
             capital amounts and classifications are also subject to 
             qualitative judgments by the regulators about components, risk 
             weightings and other factors.

          Quantitative measures established by regulation to 
             ensure capital adequacy require Troy Hill to maintain minimum 
             amounts and ratios (set forth in the table below) of Tangible 
             and Core Capital (as defined in the regulations) to total 
             assets and of Total Capital (as defined) to risk-weighted 
             assets (as defined).  Management believes, as of September 30, 
             1996 (unaudited), and June 30, 1996, that Troy Hill meets all 
             capital adequacy requirements to which it is subject.

          As of September 30, 1996, the most recent 
             notification from the Office of Thrift Supervision (OTS) 
             categorized Troy Hill as "well capitalized" under the 
             regulatory framework for prompt corrective action.  To be 
             categorized as "well capitalized," Troy Hill must maintain 
             minimum Total Risk-based, Core and Tangible ratios as set 
             forth in the accompanying table.  There are no conditions or 
             events since that notification that management believes have 
             changed the institution's category.

          Troy Hill's actual capital amounts and ratios are also presented in

          OTS regulations impose limitations on all capital 
             distributions.  The rule establishes three tiers of 
             institutions.  An institution that exceeds all fully phased-in 
             capital requirements before and after a proposed capital 
             distribution (Tier 1 Bank), may after prior notice but without 
             the approval of the OTS make capital distribution during a 
             calendar year up to 100 percent of its net income to date 
             during the calendar year plus the amount that would reduce by 
             one-half its "surplus capital ratio" (the excess capital over 
             fully phased-in capital requirements) at the beginning of the 
             calendar year.  Troy Hill is a Tier 1 Bank and, accordingly, 
             had available at September 30, 1996, and June 30, 1996, 
             approximately $4.2 million available for distribution.  In 
             October 1995, a capital distribution of $1.0 million was made 
             to the Company by Troy Hill.

(14)      Disclosures About Fair Value of Financial Instruments

          Statement of Financial Accounting Standards No. 107, 
             "Disclosure about Fair Value of Financial Instruments," (SFAS 
             107), requires disclosure of fair value information about 
             financial instruments, whether or not recognized in the 
             consolidated statements of financial condition as of September 
             30, 1996, and June 30, 1996.  SFAS 107 excludes certain 
             financial instruments and all nonfinancial instruments from 
             its disclosure requirements.  Accordingly, the aggregate fair 
             value amounts presented do not represent the underlying value 
             of the Company.  The carrying amounts reported in the 
             consolidated statements of financial condition approximate 
             fair value for cash and due from banks.

          Investment and mortgage-backed securities available 
             for sale at September 30, 1996, and June 30, 1996, are carried 
             at market value.  Fair values are based on quoted market 
             prices, dealer quotes and prices obtained from independent 
             pricing services.  Refer to note 2 of the financial statements 
             for the detail on breakdowns by type of investment products.

          The estimated fair value of loans exceeded the net 
             carrying value at September 30, 1996, and at June 30, 1996, by 
             approximately $945 (unaudited) and $842, respectively.  Loans 
             with comparable characteristics including collateral and 
             repricing structures were segregated for valuation purposes.  
             Each loan pool was separately valued utilizing a discounted 
             cash flow analysis.  Projected monthly cash flows were 
             discounted to present value using a market rate for comparable 
             loans.  Characteristics of comparable loans included remaining 
             term, coupon interest and estimated prepayment speeds. 
             Delinquent loans were evaluated separately given the impact 
             delinquency has on the projected future cash flow of the loan 
             and the approximate discount or market rate.

          The carrying amounts and estimated fair values of deposits are as
             follows:

          The carrying amounts of NOW and MMDA accounts and passbook accounts 
             approximate their fair values.  The fair value estimates above 
             do not include the benefit that results from the low-cost 
             funding provided by the deposit liabilities compared to the cost 
             of borrowing funds in the market.  Fair values for time deposits 
             are estimated using a discounted cash flow calculation that 
             applies contractual cost currently being offered in the existing 
             portfolio to current market rates being offered locally for 
             deposits of similar remaining maturities.  The mark-to-market 
             valuation adjustment for the portfolio consists of the present 
             value of the difference of these two cash flows, discounted at 
             the assumed market rate of the corresponding maturity.

          The estimated fair value of borrowed funds at 
             September 30, 1996, and June 30, 1996, was $26,965 (unaudited) 
             and $18,594 with carrying amounts of $26,950 (unaudited) and 
             $18,583, respectively.  Variable rate advances were estimated 
             to approximate their carrying amounts. The fixed rate advances 
             were valued by comparing their contractual cost to the 
             prevailing market cost.

          At September 30, 1996, and June 30, 1996, the 
             Company had no off-balance-sheet commitments to purchase 
             investment securities or mortgage-backed securities.

          The fair value of commitments to extend credit is 
             estimated using the fees currently charged to enter into 
             similar agreements, taking into account the remaining terms of 
             the agreements and the present credit worthiness of the 
             counterparties.  For fixed rate loan commitments fair value 
             also considers the difference between current levels of 
             interest rates and the committed rates.  At the reporting 
             date, the carrying value and estimated fair value on 
             commitments to extend credit were not material.

(15)      REORGANIZATION AND CONVERSION TO STOCK FORM

          During fiscal 1994, Troy Hill Federal Savings and 
             Loan Association's Board of Directors adopted a plan of 
             conversion (the Plan) whereby the Association would convert to 
             the stock form of ownership, followed by the issuance of all 
             of the Association's outstanding stock to a newly formed 
             holding company, Troy Hill Bancorp, Inc.  The conversion was 
             completed on June 24, 1994, and the Company issued 1,124,125 
             shares of its common stock.  Costs of the common stock 
             offering of $649 were deducted from the offering proceeds.

          At the completion of the conversion to stock form, 
             Troy Hill established a liquidation account in the amount of 
             retained earnings set forth in the offering prospectus 
             utilized in the conversion.  The liquidation account will be 
             maintained for the benefit of eligible savings account holders 
             who maintain deposit accounts in Troy Hill after conversion. 
             In the event of a complete liquidation (and only in such 
             event), each eligible savings account holder will be entitled 
             to receive a liquidation distribution from the liquidation 
             account in the amount of the then current adjusted balance of 
             deposit accounts held, before any liquidation distribution may 
             be made with respect to the common shares. Except for the 
             repurchase of stock and payment of dividends by Troy  Hill, 
             the existence of the liquidation account will not restrict the 
             use or further application of such retained earnings.

                                                               (Continued)

          Troy Hill may not declare or pay a cash dividend on, 
             or repurchase any of its common shares if the effect thereof 
             would cause Troy Hill's stockholders' equity to be reduced 
             below either the amount required for the liquidation account 
             or the regulatory capital requirements for insured 
             institutions.

                        AGREEMENT AND PLAN OF REORGANIZATION

                                    WITNESSETH:

    WHEREAS, the Boards of Directors of PennFirst and THB have determined
that it is in the best interests of their respective companies and their
shareholders to consummate the business combination transactions provided for
herein, including the merger of THB with and into PennFirst subject to the
terms and conditions set forth herein; and

    WHEREAS, the parties desire to provide for certain undertakings,
conditions, representations, warranties and covenants in connection with the
transactions contemplated hereby; and

    WHEREAS, as a condition and inducement to PennFirst's willingness to
enter into this Agreement, (i) THB is concurrently entering into a Stock
Option Agreement with PennFirst (the "Stock Option Agreement"), in
substantially the form attached hereto as Exhibit A, pursuant to which THB is
granting to PennFirst the option to purchase shares of THB Common Stock (as

which dissenters' rights have been asserted and duly perfected in accordance 
with Pennsylvania law (the "THB Dissenting Shares") and shares held by THB 
(including treasury shares) or PennFirst or any of their respective

    1.03      CONVERSION OF SHARES.  At the Effective Time, by virtue of the 
Merger and without any action on the part of a holder of shares of THB Common

immediately prior to the Effective Time shall remain issued and outstanding
and shall be unchanged by the Merger.

    (b)  All shares of THB Common Stock owned by THB (including treasury
shares) or PennFirst or any of their respective wholly-owned subsidiaries
shall be cancelled and retired and shall not represent capital stock of the
Surviving Corporation and shall not be exchanged for shares of PennFirst
Common Stock, cash or other consideration.

    (c)  (1)  Subject to Sections 1.08, 1.05 and 1.09 each share of THB
Common Stock issued and outstanding at the Effective Time (other than shares
to be cancelled in accordance with Section 1.03(b)) shall be converted into,
and shall be cancelled in exchange for, the right to receive, at the election
of the holder thereof:


                                     2
<PAGE>

         (i)  the number of shares of PennFirst Common Stock which is equal
    to (the "Exchange Ratio"), the quotient determined by dividing (x)
    $21.15 by (y) the Average Share Price (the "Per Share Stock
    Consideration"), or

         (ii) a cash amount equal to $21.15 per share of THB Common Stock
    (the "Per Share Cash Consideration").

         (2)  For purposes of this Agreement:

         (i)  the "Aggregate Cash Consideration" shall amount to the product
    of the number of shares of THB Common Stock (other than THB Common Stock
    owned by THB (including treasury shares) or PennFirst) outstanding at
    the Effective Time times .40 times $21.15; and

         (ii)  the "Average Share Price" shall mean the average of the high

    all applicable waiting periods.

    1.04 ELECTION AND EXCHANGE PROCEDURES

    (a)  The parties shall designate an exchange agent to act as agent (the
"Exchange Agent") for purposes of conducting the election procedure and the
exchange procedure as described in Sections 1.04 and 1.05.  No later than
seven business days following the Effective Time, PennFirst shall cause the
Exchange Agent to mail or make available to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented issued and outstanding shares of THB Common Stock (i) a notice
and letter of transmittal (which shall specify that delivery shall be
effected and risk of loss and title to the certificates theretofore
representing shares of THB Common Stock shall pass only upon proper delivery
of such certificates to the Exchange Agent) advising such holder of the
effectiveness of the Merger and the procedure for surrendering to the
Exchange Agent such certificate or certificates which immediately prior to
the Effective Time represented issued and outstanding shares of THB Common
Stock in exchange for the consideration set forth in Section 1.03(c) hereof
deliverable in respect thereof pursuant to this Agreement and (ii) an
election form in such form as PennFirst and THB shall mutually agree
("Election Form").  Each Election Form shall permit the holder (or in the
case of nominee record holders, the beneficial owner through proper
instructions and documentation) (i) to elect to receive PennFirst Common
Stock with respect to all such holder's THB Common Stock as hereinabove
provided (the "Stock Election Shares"), (ii) to elect to receive cash with
respect to all such holder's THB Common Stock as hereinabove provided (the
"Cash Election Shares"), or (iii) to indicate that such holder makes no such
election with respect to such holder's shares of THB Common Stock (the
"No-Election Shares").  Any shares of THB Common Stock with respect to which
the holder thereof shall not, as of the Election Deadline, have made such an
election by submission to the Exchange Agent of an effective, properly

                                     3

<PAGE>

completed Election Form shall be deemed to be No-Election Shares.  Any THB
Dissenting Shares shall be deemed to be Cash Election Shares, and with
respect to such shares the holders thereof shall in no event be classified as
Reallocated Stock Shares (as hereinafter defined).

    (b)  The term "Election Deadline," as used below, shall mean 5:00 p.m.,
Eastern Time, on the 20th business day following but not including the date
of mailing of the Election Form or such other date as PennFirst and THB shall
mutually agree upon.

    (c)  Any election to receive PennFirst Common Stock or cash shall have
been properly made only if the Exchange Agent shall have actually received a
properly completed Election Form by the Election Deadline.  An Election Form
will be properly completed only if accompanied by certificates representing
all shares of THB Common Stock covered thereby, subject to the provisions of
subsection (h) below of this Section 1.04.  Any Election Form may be revoked
or changed by the person submitting such Election Form to the Exchange Agent
by written notice to the Exchange Agent only if such notice is actually
received by the Exchange Agent at or prior to the Election Deadline.  The
certificate or certificates representing THB Common Stock relating to any
revoked Election Form shall be promptly returned without charge to the person
submitting the Election Form to the Exchange Agent.  The Exchange Agent shall
have reasonable discretion to determine when any election, modification or
revocation is received and whether any such election, modification or
revocation has been properly made.

    (d)  Within ten business days after the Election Deadline, the Exchange
Agent shall effect the allocation among holders of THB Common Stock of rights
to receive PennFirst Common Stock or cash in the Merger in accordance with
the Election Forms as follows:

         (i)  If the number of Cash Election Shares times the Per Share Cash
    Consideration is less than the Aggregate Cash Consideration, then:

              (1)  all Cash Election Shares (subject to Section 1.08(a) with
         respect to Company Dissenting Shares) will be converted into the
         right to receive cash,

              (2)  the Exchange Agent will select first from among the
         holders of No-Election Shares and then (if necessary) will allocate
         among the holders of Stock Election Shares (by the method of
         allocation described below), a sufficient number of Stock Election
         Shares ("Reallocated Cash Shares") such that the sum of the number
         of Cash Election Shares plus the number of Reallocated Cash Shares
         times the Per Share Cash Consideration equals the Aggregate Cash
         Consideration, and all Reallocated Cash Shares will be converted
         into the right to receive cash, and

              (3)  the No-Election Shares and Stock Election Shares which
         are not Reallocated Cash Shares will be converted into the right to
         receive PennFirst Common Stock.






                                     4

<PAGE>

         (ii) If the number of Cash Election Shares times the Per Share Cash
    Consideration is greater than the Aggregate Cash Consideration, then:

              (1)  all Stock Election Shares and all No-Election Shares will
         be converted into the right to receive PennFirst Common Stock,

              (2)  the Exchange Agent will allocate among the holders of
         Cash Election Shares (by the method of allocation described below),
         a sufficient number of Cash Election Shares (excluding any THB
         Dissenting Shares) ("Reallocated Stock Shares") such that the
         number of remaining Cash Election Shares (including THB Dissenting
         Shares) times the Per Share Cash Consideration equals the Aggregate
         Cash Consideration, and all Reallocated Stock Shares shall be
         converted into the right to receive PennFirst Common Stock, and

              (3)  the Cash Election Shares (subject to Section 1.08(a) with
         respect to THB Dissenting Shares) which are not Reallocated Stock
         Shares will be converted into the right to receive cash.

         (iii) If the number of Cash Election Shares times the Per Share
    Cash Consideration is equal to the Aggregate Cash Consideration, then
    subparagraphs (d)(i) and (ii) above shall not apply and all No-Election
    Shares and all Stock Election Shares will be converted into the right to
    receive PennFirst Common Stock.

    (e)  In the event that the Exchange Agent is required pursuant to
Section 1.04(d)(i)(2) to designate from among all Stock Election Shares the
Reallocated Cash Shares to receive cash, each holder of Stock Election Shares
shall be allocated a pro rata portion of the remainder of the total
Reallocated Cash Shares less the number of No Election Shares which are
Reallocated Cash Shares.  In the event the Exchange Agent is required
pursuant to Section 1.04(d)(ii)(2) to designate from among all holders of
Cash Election Shares the Reallocated Stock Shares to receive PennFirst Common
Stock, each holder of Cash Election Shares shall be allocated a pro rata
portion of the total Reallocated Stock Shares.

    (f)  At the Effective Time, PennFirst shall issue to the Exchange Agent
the number of shares of PennFirst Common Stock issuable and the amount of
cash payable in the Merger (which shall be held by the Exchange Agent in
trust for the holders of THB Common Stock and invested only in deposit
accounts issued by the Exchange Agent (or an FDIC-insured affiliate of the
Exchange Agent), direct obligations of the U.S. Government or obligations
issued or guaranteed by an agency thereof which carry the full faith and
credit of the United States).  Within 10 business days after the Election
Deadline, the Exchange Agent shall distribute PennFirst Common Stock and cash
as provided herein.  The Exchange Agent shall not be entitled to vote or
exercise any rights of ownership with respect to the shares of PennFirst
Common Stock held by it from time to time hereunder, except that it shall
receive and hold all dividends or other distributions paid or distributed
with respect to such shares for the account of the persons entitled thereto.





                                     5

    (g)  After the completion of the foregoing allocation, each holder of an
outstanding certificate or certificates which prior thereto represented
shares of THB Common Stock who surrenders such certificate or certificates to
the Exchange Agent will, upon acceptance thereof by the Exchange Agent, be
entitled to a certificate or certificates representing the number of full
shares of PennFirst Common Stock or the amount of cash into which the
aggregate number of shares of THB Common Stock previously represented by such
certificate or certificates surrendered shall have been converted pursuant to
this Agreement and, if such holder's shares of THB Common Stock have been
converted into PennFirst Common Stock, any other distribution theretofore
paid with respect to PennFirst Common Stock issuable in the Merger, in each
case without interest.  The Exchange Agent shall accept such certificates
upon compliance with such reasonable terms and conditions as the Exchange
Agent may impose to effect an orderly exchange thereof in accordance with
normal exchange practices.  Each outstanding certificate which prior to the
Effective Time represented THB Common Stock and which is not surrendered to
the Exchange Agent in accordance with the procedures provided for herein
shall, except as otherwise herein provided, until duly surrendered to the
Exchange Agent be deemed to evidence ownership of the number of shares of
PennFirst Common Stock or the right to receive the amount of cash into which
such THB Common Stock shall have been converted.  After the Effective Time,
there shall be no further transfer on the records of THB of certificates
representing shares of THB Common Stock and if such certificates are
presented to THB for transfer, they shall be cancelled against delivery of
certificates for PennFirst Common Stock or cash as hereinabove provided.  No
dividends which have been declared will be remitted to any person entitled to
receive shares of PennFirst Common Stock under this Section 1.04 until such
person surrenders the certificate or certificates representing THB Common
Stock, at which time such dividends shall be remitted to such person, without
interest.

    (h)  PennFirst shall not be obligated to deliver cash and/or a
certificate or certificates representing shares of PennFirst Common Stock to
which a holder of THB Common Stock would otherwise be entitled as a result of
the Merger until such holder surrenders the certificate or certificates
representing the shares of THB Common Stock for exchange as provided in this
Section 1.04, or, in default thereof, an appropriate affidavit of loss and
indemnity agreement and/or a bond as may be required in each case by
PennFirst.  If any certificates evidencing shares of PennFirst Common Stock
are to be issued in a name other than that in which the certificate
evidencing THB Common Stock surrendered in exchange therefor is registered,
it shall be a condition of the issuance thereof that the certificate so
surrendered shall be properly endorsed or accompanied by an executed form of
assignment separate from the certificate and otherwise in proper form for
transfer and that the person requesting such exchange pay to the Exchange
Agent any transfer or other tax required by reason of the issuance of a
certificate for shares of PennFirst Common Stock in any name other than that
of the registered holder of the certificate surrendered or otherwise
establish to the satisfaction of the Exchange Agent that such tax has been
paid or is not payable.

    (i)  Any portion of the shares of PennFirst Common Stock and cash
delivered to the Exchange Agent by PennFirst pursuant to Section 1.04(f) that
remains unclaimed by the shareholders of THB for six months after the
Effective Time (as well as any proceeds from any 





                                     6

<PAGE>

investment thereof) shall be delivered by the Exchange Agent to PennFirst.  
Any shareholders of THB who have not theretofore complied with Section 
1.04(g) shall thereafter look only to PennFirst for the consideration 
deliverable in respect of each share of THB Common Stock such shareholder 
holds as determined pursuant to this Agreement without any interest thereon.  
If outstanding certificates for shares of THB Common Stock are not 
surrendered or the payment for them is not claimed prior to the date on which 
such shares of PennFirst Common Stock or cash would otherwise escheat to or 
become the property of any governmental unit or agency, the unclaimed items 
shall, to the extent permitted by abandoned property and any other applicable 
law, become the property of PennFirst (and to the extent not in its 
possession shall be delivered to it), free and clear of all claims or 
interest of any person previously entitled to such property.  Neither the 
Exchange Agent nor any party to this Agreement shall be liable to any holder 
of stock represented by any certificate for any consideration paid to a 
public official pursuant to applicable abandoned property, escheat or similar 
laws.  PennFirst and the Exchange Agent shall be entitled to rely upon the 
stock transfer books of THB to establish the identity of those persons 
entitled to receive consideration specified in this Agreement, which books 
shall be conclusive with respect thereto.  In the event of a dispute with 
respect to ownership of stock represented by any certificate, PennFirst and 
the Exchange Agent shall be entitled to deposit any consideration represented 
thereby in escrow with an independent third party and thereafter be relieved 
with respect to any claims thereto.

    1.05 NO FRACTIONAL SHARES.  Notwithstanding any other provision of this
Agreement, neither certificates nor scrip for fractional shares of PennFirst
Common Stock shall be issued in the Merger.  Each holder who otherwise would
have been entitled to a fraction of a share of PennFirst Common Stock shall
receive in lieu thereof cash (without interest) in an amount determined by
multiplying the fractional share interest to which such holder would
otherwise be entitled by the Average Share Price.  No such holder shall be
entitled to dividends, voting rights or any other rights in respect of any
fractional share.

    1.06 STOCK OPTIONS.

    (a)  Immediately before the Effective Time, each option with respect to
THB Common Stock (a "THB Stock Option") that has been issued pursuant to
THB's 1994 Stock Option Plan and is outstanding and exercisable at the
Effective Time shall be cancelled and converted into the right to receive
from THB or PennFirst, subject to required withholding taxes, if any, (x)
cash in an amount equal to the difference between the exercise price of such
THB Stock Option and the Per Share Cash Consideration for each share of THB
Common Stock subject to such THB Stock Option or (y) an option to purchase
shares of PennFirst Common Stock in an amount and at an exercise price
determined as provided below (and otherwise subject to the terms of THB's
1994 Stock Option Plan):




                                     7

<PAGE>


         (1)  the number of shares of PennFirst Common Stock to be
    subject to the new option shall be equal to the product of the
    number of shares of THB Common Stock subject to the original option
    and the Exchange Ratio, provided that any fractional shares of
    PennFirst Common Stock resulting from such multiplication shall be
    rounded down to the nearest share; and

         (2)  the exercise price per share of PennFirst Common Stock
    under the new option shall be equal to the exercise price per share
    of THB Common Stock under the original option divided by the
    Exchange Ratio, provided that such exercise price shall be rounded
    up to the nearest cent.

The duration and other terms of the new option shall be the same as the
original option, except that all references to THB shall be deemed to be
references to PennFirst.

         (b)  Within thirty (30) business days after the Effective Time,
PennFirst shall file with the Securities and Exchange Commission (the "SEC")
a registration statement on an appropriate form under the Securities Act of
1933, as amended (the "Securities Act") with respect to the shares of
PennFirst Common Stock subject to options to acquire PennFirst Common Stock
issued pursuant to Section 1.06(a) hereof, and shall use its reasonable best
efforts to maintain the current status of the prospectus contained therein,
as well as comply with applicable state securities or "blue sky" law, for so
long as such options remain outstanding.

    1.07 WITHHOLDING RIGHTS.  PennFirst (through the Exchange Agent, if
applicable) shall be entitled to deduct and withhold from any amounts
otherwise payable pursuant to this Agreement to any holder of shares of THB
Common Stock such amounts as PennFirst is required under the Internal Revenue
Code of 1986, as amended ("Code") or any provision of state, local or foreign
tax law to deduct and withhold with respect to the making of such payment. 
Any amounts so withheld shall be treated for all purposes of this Agreement
as having been paid to the holder of THB Common Stock in respect of which
such deduction and withholding was made by PennFirst.

    1.08 DISSENTING SHARES.  Each outstanding share of THB 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 "THB
Dissenting Shares") shall not be converted into or represent a right to
receive shares of PennFirst Common Stock or cash hereunder, and the holder
thereof shall be entitled only to such rights as are granted by the PBCL. 
THB shall give PennFirst prompt notice upon receipt by THB of any such
written demands for payment of the fair value of such shares of THB Common
Stock and of withdrawals of such demands and any other instruments provided
pursuant to the PBCL (any shareholder duly making such demand being
hereinafter called a "Dissenting Shareholder").  Any payments made in respect
of THB Dissenting Shares shall be made by PennFirst.  If any Dissenting
Shareholder shall effectively withdraw or lose (through failure to perfect or
otherwise) his right to such payment at or prior to the Effective Time, such
holder's shares of THB Common Stock shall be converted into a right to
receive cash or PennFirst Common Stock in accordance with the applicable





                                     8


<PAGE>


provisions of this Agreement.  If such holder shall effectively withdraw or
lose (through failure to perfect or otherwise) his right to such payment
after the Effective Time, each share of THB Common Stock of such holder shall
be converted on a share by share basis into either the right to receive cash
or PennFirst Common Stock as PennFirst shall determine.

    1.09 ANTI-DILUTION PROVISIONS.  The Exchange Ratio, the Per Share Stock
Consideration, the Per Share Cash Consideration and the Stock Amount shall be
subject to appropriate adjustments as mutually agreed to by PennFirst and THB
in the event that, subsequent to the date of this Agreement but prior to the
Effective Time, the outstanding shares of PennFirst Common Stock shall have
been increased, decreased, changed into or exchanged for a different number
or kind of shares or securities through reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split or other
like changes in PennFirst's capitalization.  Nothing contained herein shall
be deemed to permit any action which may be proscribed by this Agreement.

    1.10 ADDITIONAL ACTIONS.  If at any time after the Effective Time the
Surviving Corporation shall consider that any further assignments or
assurances in law or any other acts are necessary or desirable to (i) vest,
perfect or confirm, of record or otherwise, in the Surviving Corporation its
rights, title or interest in, to or under any of the rights, properties or
assets of THB acquired or to be acquired by the Surviving Corporation as a
result of, or in connection with, the Merger, or (ii) otherwise carry out the
purposes of this Agreement, THB and its proper officers and directors shall
be deemed to have granted to the Surviving Corporation an irrevocable power
of attorney to execute and deliver all such proper deeds, assignments and
assurances in law and to do all acts necessary or proper to vest, perfect or
confirm title to and possession of such rights, properties or assets in the
Surviving Corporation and otherwise to carry out the purposes of this
Agreement; and the proper officers and directors of the Surviving Corporation
are fully authorized in the name of THB or otherwise to take any and all such
action.

                       REPRESENTATIONS AND WARRANTIES OF THB

    References to "THB Disclosure Schedules" shall mean all of the
disclosure schedules required by this Article II, dated as of the date hereof
and referenced to the specific sections and subsections of Article II of this
Agreement, which have been delivered by THB to PennFirst.  THB hereby
represents and warrants to PennFirst as follows as of the date hereof:

    2.01.     CORPORATE ORGANIZATION.

    (a)  THB is a corporation duly organized, validly existing and in good
standing under the laws of the Commonwealth of Pennsylvania.  THB has the
corporate power and authority to own or lease all of its properties and
assets and to carry on its business as it is now being 





                                     9

<PAGE>

conducted and is duly licensed or qualified to do business and is in good
standing in each jurisdiction in which the nature of the business conducted
by it or the character or location of the properties and assets owned or
leased by it makes such licensing or qualification necessary, except where
the failure to be so licensed, qualified or in good standing would not have a
material adverse effect on the business, operations, assets or financial
condition of THB and the THB Subsidiaries (as defined below) taken as a
whole.  THB is registered as a thrift holding company under the Home Owners'
Loan Act, as amended ("HOLA").  THB Disclosure Schedule 2.01(a) sets forth
true and complete copies of the Articles of Incorporation or other governing
instrument and Bylaws of THB and the THB Subsidiaries as in effect on the
date hereof.  

    (b)  The only direct or indirect subsidiaries of THB are Troy Hill
Federal Savings Bank ("Troy Hill") and THF, Inc. (together the "THB
Subsidiaries").  Each of the THB Subsidiaries (i) is duly organized, validly
existing and in good standing under the laws of its respective jurisdiction
of incorporation, (ii) has the corporate power and authority to own or lease
all of its properties and assets and to conduct its business as it is now
being conducted, and (iii) is duly licensed or qualified to do business and
is in good standing in each jurisdiction in which the nature of the business
conducted by it or the character or location of the properties and assets
owned or leased by it makes such licensing or qualification necessary, except
where the failure to be so licensed, qualified or in good standing would not
have a material adverse effect on the business, operations, assets or
financial condition of THB and the THB Subsidiaries taken as a whole.  THB
and Troy Hill are in good standing with their  appropriate federal thrift
regulatory agencies and each has satisfied in all material respects all
commitments, financial or otherwise, as  may have been agreed upon with such
thrift regulatory agencies.  Except as set forth in THB Disclosure Schedule
2.01(b) and other than the THB Subsidiaries, THB does not own or control,
directly or indirectly, greater than a 5% equity interest in any corporation,
company, association, partnership, joint venture or other entity.

    2.02.     CAPITALIZATION.  The authorized capital stock of THB consists
of 10,000,000 shares of THB Common Stock, of which 1,067,917 are issued and
outstanding and 56,208 of which are held in treasury as of the date hereof,
and 5,000,000 shares of preferred stock, of which no shares are issued and
outstanding as of the date hereof.  All issued and outstanding shares of
capital stock of THB, and all issued and outstanding shares of capital stock
of each of the THB Subsidiaries, have been duly authorized and validly issued
and are fully paid, nonassessable and free of preemptive rights.  All of the
outstanding shares of capital stock of each of the THB Subsidiaries are owned
by THB free and clear of any liens, encumbrances, charges, restrictions or
rights of third parties of any kind whatsoever, and, except for options
granted to PennFirst pursuant to the Option Agreement and for options to
purchase 70,253 shares of THB Common Stock which have been granted pursuant
to THB's 1994 Stock Option Plan, and which are outstanding, none of THB or
either of the THB Subsidiaries has or is bound by any outstanding
subscriptions, options, warrants, calls, commitments or agreements of any
character calling for the transfer, purchase or issuance of any shares of
capital stock of THB or either of the THB Subsidiaries or any securities
representing the right to purchase or otherwise receive any shares of such
capital stock or any securities convertible into or representing the right to
purchase or subscribe for any such stock.

    2.03.     AUTHORITY; NO VIOLATION.

    (a)  Subject to the approval of this Agreement and the Agreement of
Merger and the transactions contemplated hereby and thereby by the
stockholders of THB, THB has full corporate power and authority to execute
and deliver this Agreement and the Agreement of Merger and to consummate the
transactions contemplated hereby and thereby in accordance with the terms
hereof and thereof.  The execution and delivery of this Agreement and the
Agreement of Merger and the consummation of the transactions contemplated
hereby and thereby have been duly and validly approved by the Board of
Directors of THB.  Except for the approval of THB's stockholders of this
Agreement and the Agreement of Merger, no other corporate proceedings on the
part of THB are necessary to consummate the transactions so contemplated. 
This Agreement and the Agreement of Merger have been duly and validly
executed and delivered by THB and constitute valid and binding obligations of
THB, enforceable against it in accordance with and subject to their terms,
except as limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting creditors' rights generally, and
except that the availability of equitable remedies (including, without
limitation, specific performance) is within the discretion of the appropriate
court.

    (b)  None of the execution and delivery of this Agreement and the
Agreement of Merger by THB, nor the consummation by THB of the transactions
contemplated hereby and thereby in accordance with the terms hereof and
thereof, or compliance by THB with any of the terms or provisions hereof or
thereof, will (i) violate any provision of the Articles of Incorporation or
other governing instrument or Bylaws of THB or any of the THB Subsidiaries,
(ii) assuming that the consents and approvals set forth below are duly
obtained, violate any statute, code, ordinance, rule, regulation, judgment,

encumbrance upon any of the respective properties or assets of THB or either
of the THB Subsidiaries under any of the terms, conditions or provisions of
any note, bond, mortgage, indenture, deed of trust, license, lease, agreement
or other instrument or obligation to which THB or any of the THB Subsidiaries
is a party, or by which any of their respective properties or assets may be
bound or affected, except, with respect to (ii) and (iii) above, such as
individually or in the aggregate will not have a material adverse effect on
the business, operations, assets or financial condition of THB and the THB
Subsidiaries taken as a whole and which will not prevent or delay the
consummation of the transactions contemplated hereby.  Except as set forth in
THB Disclosure Schedule 2.03(b) and for consents and approvals of or filings
or registrations with or notices to the Securities and Exchange Commission
("Commission"), the Secretary of State of the Commonwealth of Pennsylvania,
the Office of Thrift Supervision ("OTS") and the stockholders of THB, no
consents or approvals of or filings or registrations with or notices to any
federal, state, municipal or other governmental or regulatory commission,
board, agency, or non-governmental third party are required on behalf of THB
in connection with (a) the execution and

interim financial statements are not audited and are not prepared with
related notes but reflect all adjustments which are, in the opinion of THB,
necessary for a fair presentation of such financial statements).

    (b)  Each of the financial statements referred to in this Section 2.04
(including the related notes, where applicable) has been or will be, as the

material adverse effect on the business, operations, assets or financial
condition of THB and the THB Subsidiaries taken as a whole.  None of THB or
any of the THB Subsidiaries is a party to any order, judgment or decree which
materially adversely affects the business, operations, assets or financial

whether or not disputed, accrued or applicable.  Except as set forth in THB

its Affiliates have been examined by the Internal Revenue Service ("IRS") (or

voluntary 



                                     13

<PAGE>

change in accounting method initiated by THB or any Affiliate (nor
does THB have any knowledge that the IRS has proposed any such adjustment or
change of accounting method), or (iv) has filed a consent pursuant to Section
341(f) of the Code or agreed to have Section 341(f)(2) of the Code apply.

    (c)  For purposes of this Agreement, "Taxes" shall mean all taxes,
charges, fees, levies or other assessments, including, without limitation,

Plans").  THB has previously furnished to PennFirst true and complete copies
of each of the THB Plans together with (i) the most recent actuarial and
financial reports prepared with respect to any qualified THB Plans, (ii) the
most recent annual reports filed with any government agency, and (iii) all
rulings and determination letters and any open requests for rulings or
letters that pertain to any qualified THB Plans.

    (b)  Each THB Plan has been operated in compliance in all material
respects with the applicable provisions of ERISA, the Code, all regulations,
rulings and announcements promulgated or issued thereunder, and all other
applicable governmental laws and regulations.

    (c)  Neither THB nor any THB Subsidiary participates in or has incurred
any liability under Section 4201 of ERISA for a complete or partial
withdrawal from a multi-employer plan (as such term is defined in ERISA).

    (d)  The present value of all accrued benefits under each of the THB
Plans subject to Title IV of ERISA did not, as of the latest valuation date
of each such Plan, exceed the then current value of the assets of such plans
allocable to such accrued benefits, based upon the actuarial and accounting
assumptions currently utilized for such THB Plans.

    (e)  Neither THB nor either of the THB Subsidiaries, nor, to the best
knowledge of THB, any trustee, fiduciary or administrator of an THB Plan or
any trust created thereunder, has engaged in a "prohibited transaction," as
such term is defined in Section 4975 of the Code, which could subject THB or
either of the THB Subsidiaries, or, to the best knowledge of THB, any
trustee, fiduciary or administrator thereof, to the tax or penalty on
prohibited transactions imposed by said Section 4975.

nor have there been any "reportable events" with respect to any THB Plan, as
that term is defined in Section 4043(b) of ERISA.

    (g)  No THB Plan or any trust created thereunder has incurred any
"accumulated funding deficiency," as such term is defined in Section 302 of
ERISA.

within the meaning of Section 401(a) of the Code has been determined by the
IRS to be so qualified, and THB is not aware of any fact or circumstance
which would adversely affect the qualified status of any such Plan.

    (a)  THB has previously delivered or made available to PennFirst a

definitive proxy statement or other communication, as of its date, complied

and did not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements made therein, in light of the circumstances under which they
were made, not misleading; provided that information as of a later date shall

2.09(b) lists all examinations of THB or of the THB Subsidiaries conducted by
the applicable thrift regulatory authorities since January 1, 1990 and the
dates of any responses thereto submitted by THB.  In connection with the most
recent examinations of THB or the THB Subsidiaries by the applicable thrift
regulatory authorities, neither THB nor any THB Subsidiary was required to
correct or change any action, procedure or proceeding which THB or such THB
Subsidiary believes has not been now corrected or changed as required.

    2.10.     THB INFORMATION.  None of the information relating to THB and
the THB Subsidiaries to be contained in (i) the Registration Statement on
Form S-4 to be filed by PennFirst in connection with the issuance of shares
of PennFirst Common Stock pursuant to the Merger, as amended or supplemented

material fact or omit to state a material fact necessary to make the 
statements therein, in light of the circumstances under which they were made, 
not misleading, provided that information as of a later date shall be deemed

    2.11.     COMPLIANCE WITH APPLICABLE LAW.

    (a)  THB and each of the THB Subsidiaries has all permits, licenses,
certificates of authority, orders and approvals of, and has made all filings,
applications and registrations with, federal, state, local and foreign
governmental or regulatory bodies that are required in order to permit it to

respect to any order, writ, injunction or decree of any court, or in default
under any order, license, regulation or demand of any governmental agency,
any of which violations or defaults could have a material adverse effect on
the business, operations, assets or financial condition of THB and the THB
Subsidiaries taken as a whole; and neither THB nor any THB Subsidiary has

    (b)  Neither THB nor any THB Subsidiary is in default or in

the THB Subsidiaries taken as a whole or the transactions contemplated
hereby, under any contract, agreement, commitment, arrangement, lease,

assets, business or operations may be bound or affected, whether entered into
in the ordinary course of business or otherwise and whether written or oral,
and there has not occurred any event that with the lapse of time or the

    2.14.     PROPERTIES AND INSURANCE.

    (a)  All real and personal property owned by THB or any of the THB
Subsidiaries or presently used by any of them in their respective business is
in an adequate condition (ordinary wear and tear excepted) and is sufficient
to carry on the business of THB and the THB Subsidiaries in the ordinary
course of business consistent with their past practices.  THB and the THB
Subsidiaries have good and, as to owned real property, marketable title to
all material assets and properties, whether real or personal, tangible or
intangible, reflected in THB's consolidated statement of financial condition
as of March 31, 1996, or owned and acquired subsequent thereto (except to the
extent that such assets and properties have been disposed of for fair value
in the ordinary course of business since March 31, 1996), subject to no
encumbrances, liens, mortgages, security interests or pledges, except (i)
those items that secure liabilities that are reflected in said consolidated
statement of financial condition or the notes thereto or have been incurred
in the ordinary course of business after the date of such consolidated
statement of financial condition, (ii) statutory liens for amounts not yet
delinquent or which are being contested in good faith, (iii) such
encumbrances, liens, mortgages, security interests, pledges and title
imperfections that are not in the aggregate material to the business,
operations, assets or financial condition of THB and the THB Subsidiaries
taken as a whole, and (iv) with respect to owned real property, title
imperfections noted in title reports prior to the date hereof.  THB and the
THB Subsidiaries as lessees have the right under valid and subsisting leases
to occupy, use, possess and control all property leased by them in all
material respects as presently occupied, used, possessed and controlled by
THB and the THB Subsidiaries and the consummation of the transactions
contemplated hereby and by the Agreement of Merger will not affect any such
right.  THB Disclosure Schedule 2.14(a) sets forth an accurate listing of
each lease pursuant to which THB or any of the THB Subsidiaries acts as
lessor or lessee, including the expiration date and the terms of any renewal
options which relate to the same.

    (b)  The business operations and all insurable properties and assets of
THB and the THB Subsidiaries are insured for their benefit against all risks
which, in the reasonable judgment of the management of THB, should be insured
against, in each case under valid, binding and enforceable policies or bonds
issued by insurers of recognized responsibility, in such amounts with such
deductibles and against such risks and losses as are in the opinion of the
management of THB adequate for the business engaged in by THB and the THB
Subsidiaries.  As of the date hereof, neither THB nor either of the THB
Subsidiaries has received any notice of cancellation or notice of a material
amendment of any such insurance policy or bond or is in default under 


                                     18

such policy or bond, no coverage thereunder is being disputed and all 
material claims thereunder have been filed in a timely fashion.

allowance for loan losses reflected on THB's consolidated statements of
financial condition included in the consolidated financial statements
referred to in Section 2.04 hereof is, or will be in the case of subsequently

management adequate in all material respects as of their respective dates
under the requirements of generally accepted accounting principles to provide
for reasonably anticipated losses on outstanding loans net of recoveries.

condition included in the consolidated financial statements referred to in
Section 2.04 hereof is, or will be in the case of subsequently delivered

Act.

    2.19.     BROKER FEES.  Except as set forth in THB Disclosure Schedule
2.19, none of THB, either of the THB Subsidiaries or any of the respective

of this Agreement, which have been delivered by PennFirst to THB.  PennFirst
hereby represents and warrants to THB as follows as of the date hereof:

    3.01.     CORPORATE ORGANIZATION.

    (a)  PennFirst is a corporation duly organized, validly existing and in
good standing under the laws of the Commonwealth of Pennsylvania.  PennFirst
has the corporate power and authority to own or lease all of its properties
and assets and to carry on its business as it is now being conducted and is
duly licensed or qualified to do business and is in good standing in each
jurisdiction in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it
makes such licensing or qualification necessary, except where the failure to
be so licensed, qualified or in good standing would not have a material
adverse effect on the business, operations, assets or financial condition of
PennFirst and the PennFirst Subsidiaries (as defined below) taken as a whole. 
PennFirst is registered as a thrift holding company under the HOLA. 
PennFirst Disclosure Schedule 3.01(a) sets forth true and complete copies of
the Articles of Incorporation or other governing instrument and Bylaws of
PennFirst and the PennFirst Subsidiaries as in effect on the date hereof.

FSB  ("ESBB"), PennFirst Financial Services, Inc., Ellwood Service
Corporation, Amsco, Inc. and Shady Park II Townhouse Associates (a limited

Subsidiaries (i) is duly organized, validly existing and in good standing
under the laws of its respective jurisdiction of incorporation, (ii) has the
corporate power and authority to own or lease all of its properties and
assets and to conduct its business as it is now being conducted, and (iii) is
duly licensed or qualified to do business and is in good standing in each
jurisdiction in which the nature of the business conducted by it or the

or financial condition of PennFirst and the PennFirst Subsidiaries taken as a 
whole.  PennFirst and ESBB are in good standing with their appropriate 
federal thrift regulatory agencies and each has satisfied in all material 
respects all commitments, financial or otherwise, as may have been agreed 
upon with such thrift regulatory agencies.  Other than the PennFirst 
Subsidiaries, PennFirst does not own or control, directly or indirectly, 
greater than a 5% equity interest in any corporation, company, association, 
partnership, joint venture or other entity.

consists of 10,000,000 shares of PennFirst Common Stock, of which 3,909,184

preferred stock, par value $.01 per share, of which no shares are issued and
outstanding as of the date hereof.  All issued and outstanding shares of
capital stock of PennFirst, and all issued and outstanding shares of capital
stock of each of the PennFirst Subsidiaries, have been duly authorized and
validly issued and are fully paid, nonassessable and free of preemptive
rights.  All of the outstanding shares of capital stock of each of the

thereto after the date hereof), none of PennFirst or any of the PennFirst
Subsidiaries has or is bound by any outstanding subscriptions, options,
warrants, calls, commitments or agreements of any character calling for the
transfer, purchase or issuance of any shares of capital stock of PennFirst or
any of the PennFirst Subsidiaries or any securities representing the right to
purchase or otherwise receive any shares of such capital stock or any
securities convertible into or representing the right to purchase or
subscribe for any such stock.

    3.03.     AUTHORITY; NO VIOLATION.

    (a)  Subject to the approval of this Agreement and the Agreement of
Merger and the transactions contemplated hereby and thereby by the
stockholders of PennFirst, PennFirst has full corporate power and authority
to execute and deliver this Agreement and the Agreement of Merger and to
consummate the transactions contemplated hereby and thereby in accordance

    (b)  None of the execution and delivery of this Agreement and the
Agreement of Merger by PennFirst, nor the consummation by PennFirst of the
transactions contemplated hereby and thereby in accordance with the terms
hereof and thereof, or compliance by PennFirst with any of the terms or
provisions hereof or thereof, will (i) violate any provision of the Articles
of Incorporation or other governing instrument or Bylaws of PennFirst or any
of the PennFirst Subsidiaries, (ii) assuming that the consents and approvals
set forth below are duly obtained, violate any statute, code, ordinance,

Subsidiaries is a party, or by which any of their respective properties or
assets may be bound or affected, except, with respect to (ii) and (iii)
above, such as individually or in the aggregate will not have a material
adverse effect on the business, operations, assets or financial condition of
PennFirst and the PennFirst Subsidiaries taken as a whole and which will not
prevent or delay the consummation of the transactions contemplated hereby. 
Except for consents and approvals of or filings or registrations with or
notices to the Commission, the Secretary of State of the Commonwealth of
Pennsylvania, the OTS and the stockholders of PennFirst, no consents or
approvals of or filings or registrations with or notices to any federal,
state, municipal or other governmental or regulatory commission, board,
agency or non-governmental third party are required on behalf of PennFirst in
connection with (a) the execution and delivery of this Agreement and the

    (c)  Neither PennFirst nor any PennFirst Subsidiary participates in or
has incurred any liability under Section 4201 of ERISA for a complete or
partial withdrawal from a multi-employer plan (as such term is defined in
ERISA).

    (d)  The present value of all accrued benefits under each of the
PennFirst Plans subject to Title IV of ERISA did not, as of the latest
valuation date of each such Plan, exceed the then current value of the assets
of such plans allocable to such accrued benefits, based upon the actuarial
and accounting assumptions currently utilized for such PennFirst Plans.

    (e)  Neither PennFirst nor any of the PennFirst Subsidiaries, nor, to
the best knowledge of PennFirst, any trustee, fiduciary or administrator of a
PennFirst Plan or any trust created thereunder, has engaged in a "prohibited
transaction," as such term is defined in Section 4975 of the Code, which
could subject PennFirst or any of the PennFirst Subsidiaries, or, to the best
knowledge of PennFirst, any trustee, fiduciary or administrator thereof, to
the tax or penalty on prohibited transactions imposed by said Section 4975.

    (f)  No PennFirst Plan or any trust created thereunder has been
terminated, nor have there been any "reportable events" with respect to any
PennFirst Plan, as that term is defined in Section 4043(b) of ERISA.

    (g)  No PennFirst Plan or any trust created thereunder has incurred any
"accumulated funding deficiency," as such term is defined in Section 302 of
ERISA.

    (h)  Each of the PennFirst Plans which is intended to be a qualified
plan within the meaning of Section 401(a) of the Code has been determined by

with the OTS and the FDIC in correct form the monthly, quarterly and annual

    3.10.     PENNFIRST INFORMATION.  None of the information relating to
PennFirst and the PennFirst Subsidiaries to be contained in (i) the Form S-4

state a material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, provided that
information as of a later date shall be deemed to modify information as of an

    (a)  PennFirst and each of the PennFirst Subsidiaries has all permits,
licenses, certificates of authority, orders and approvals of, and has made
all filings, applications and registrations with, federal, state, local and
foreign governmental or regulatory bodies that are required in order to
permit it to carry on its business as it is presently being conducted and the
absence of which could have a material adverse effect on the business,
operations, assets or financial condition of PennFirst and the PennFirst
Subsidiaries taken as a whole; all such permits, licenses, certificates of
authority, orders and approvals are in full force and effect; and to the best
knowledge of PennFirst and the PennFirst Subsidiaries, no suspension or
cancellation of any of the same is threatened.

    (b)  Neither PennFirst nor any of the PennFirst Subsidiaries is in
violation of its respective Articles of Incorporation or other governing
instrument or Bylaws, or of any applicable federal, state or local law or
ordinance or any order, rule or regulation of any federal, state, local or
other governmental agency or body (including, without limitation, all
banking, securities, municipal securities, safety, health, zoning,
anti-discrimination, antitrust, and wage and hour laws, ordinances, orders,
rules and regulations), or in default with respect to any order, writ,
injunction or decree of any court, or in default under any order, license,
regulation or demand of any governmental agency, any of which violations or
defaults could have a 


                                     27

<PAGE>

material adverse effect on the business, operations, assets or financial 
condition of PennFirst and the PennFirst Subsidiaries taken as a whole; and 
neither PennFirst nor any PennFirst Subsidiary has received any notice or 
communication from any federal, state or local governmental authority 
asserting that PennFirst or any PennFirst Subsidiary is in violation of any 
of the foregoing which could have a material adverse effect on the business,  
operations, assets or financial condition of PennFirst and the PennFirst 
Subsidiaries taken as a whole.  Neither PennFirst nor any PennFirst 
Subsidiary is subject to any regulatory or supervisory cease and desist 
order, agreement, written directive, memorandum of understanding or written 
commitment (other than those of general applicability to all savings 
associations issued by governmental authorities), and none of them has 
received any written communication requesting that they enter into any of the 
foregoing.

    3.12.     DEPOSIT INSURANCE AND OTHER REGULATORY MATTERS.

    (a)  The deposit accounts of ESBB are insured by the Savings Association
Insurance Fund administered by the FDIC to the maximum extent permitted by

    (a)  All real and personal property owned by PennFirst or any of the
PennFirst Subsidiaries or presently used by any of them in their respective
business is in an adequate condition (ordinary wear and tear excepted) and is
sufficient to carry on the business of PennFirst and the PennFirst
Subsidiaries in the ordinary course of business consistent with their past
practices.  PennFirst and the PennFirst Subsidiaries have good and, as to
owned real property, marketable title to all material assets and properties,
whether real or personal, tangible or intangible, reflected in PennFirst's
consolidated statement of financial condition as of June 30, 1996, or owned
and acquired subsequent thereto (except to the extent that such assets and
properties have been disposed of for fair value in the ordinary course of
business since June 30, 1996), subject to no encumbrances, liens, mortgages,
security interests or pledges, except (i) those items that secure liabilities
that are reflected in said consolidated statement of financial condition or
the notes thereto or have been incurred in the ordinary course of business
after the date of such consolidated statement of financial condition, (ii)
statutory liens for amounts not yet delinquent or which are being contested
in good faith, (iii) such encumbrances, liens, mortgages, 


                                     28

<PAGE>

security interests, pledges and title imperfections that are not in the 
aggregate material to the business, operations, assets or financial condition 
of PennFirst and the PennFirst Subsidiaries taken as a whole, and (iv) with 
respect to owned real property, title imperfections noted in title reports 
prior to the date hereof.  PennFirst and the PennFirst Subsidiaries as 
lessees have the right under valid and subsisting leases to occupy, use, 
possess and control all property leased by them in all material respects as 
presently occupied, used, possessed and controlled by PennFirst and the 
PennFirst Subsidiaries and the consummation of the transactions contemplated 
hereby and by the Agreement of Merger will not affect any such right.  

    (b)  The business operations and all insurable properties and assets of
PennFirst and the PennFirst Subsidiaries are insured for their benefit
against all risks which, in the reasonable judgment of the management of
PennFirst, should be insured against, in each case under valid, binding and
enforceable policies or bonds issued by insurers of recognized
responsibility, in such amounts with such deductibles and against such risks
and losses as are in the opinion of the management of PennFirst adequate for
the business engaged in by PennFirst and the PennFirst Subsidiaries.  As of
the date hereof, neither PennFirst nor either of the PennFirst Subsidiaries
has received any notice of cancellation or notice of a material amendment of
any such insurance policy or bond or is in default under such policy or bond,
no coverage thereunder is being disputed and all material claims thereunder
have been filed in a timely fashion.

    3.14.     ENVIRONMENTAL MATTERS.  

    (a)  To the best knowledge of PennFirst and the PennFirst Subsidiaries,
neither PennFirst nor any of the PennFirst Subsidiaries has been or is in
violation of or liable under any Environmental Law, except any such
violations or liabilities which would not singly or in the aggregate have a
material adverse effect on the business, operations, assets or financial
condition of PennFirst and PennFirst Subsidiaries taken as a whole.

    (b)  To the best knowledge of PennFirst and the PennFirst Subsidiaries,
none of the Loan Portfolio Properties and Other Properties Owned by PennFirst
or the PennFirst Subsidiaries has been or is in violation of or liable under
any Environmental Law, except any such violations or liabilities which singly
or in the aggregate would not have a material adverse effect on the business,
operations, assets or financial condition of PennFirst and the PennFirst
Subsidiaries taken as a whole.

    (c)  To the best knowledge of PennFirst and the PennFirst Subsidiaries,
there are no actions, suits, demands, notices, claims, investigations or
proceedings pending or threatened relating to the liability of the Loan
Portfolio Properties and Other Properties Owned by PennFirst or the PennFirst
Subsidiaries under any Environmental Law, including without limitation any
notices, demand letters or requests for information from any federal or state
environmental agency relating to any such liabilities under or violations of
Environmental Law, except such which would not have or result in a material
adverse effect on the business, operations, assets or financial condition of
PennFirst and the PennFirst Subsidiaries taken as a whole.

    3.15.     ALLOWANCE FOR LOAN LOSSES AND REAL ESTATE OWNED.  The
allowance for loan losses reflected on PennFirst's consolidated statements of
financial condition included in the consolidated financial statements
referred to in Section 3.04 hereof is, or will be in the case of subsequently
delivered financial statements, as the case may be, in the opinion of
PennFirst's management adequate in all material respects as of their
respective dates under the requirements of generally accepted accounting
principles to provide for reasonably anticipated losses on outstanding loans
net of recoveries.  The real estate owned reflected on the consolidated
statements of financial condition included in the consolidated financial
statements referred to in Section 3.04 hereof is, or will be in the case of
subsequently delivered financial statements, as the case may be, carried at
the lower of cost or fair value, or the lower of cost or net realizable
value, as required by generally accepted accounting principles.

    3.16.     MINUTE BOOKS.  Since January 1, 1992, the minute books of
PennFirst and the PennFirst Subsidiaries contain complete and accurate
records of all meetings and other corporate action held or taken by their
respective Boards of Directors (including committees of their respective
Boards of Directors) and stockholders.

    3.17.     BROKER FEES.  Except as set forth in PennFirst Disclosure
Schedule 3.17, neither PennFirst nor any of its directors or officers has
employed any consultant, broker or finder or incurred any liability for any
consultant's, broker's or finder's fees or commissions in connection with any
of the transactions contemplated by this Agreement.

    3.18.     DISCLOSURES.  No representation or warranty contained in
Article III of this Agreement, and no statement contained in the PennFirst
Disclosure Schedules, contains any untrue statement of a material fact or
omits to state a material fact necessary in order to make the statements
herein or therein not misleading.


                                     ARTICLE IV

    4.04.     CURRENT INFORMATION.  During the period from the date hereof
to the Effective Time, each party will cause one or more of its designated
representatives to confer on a monthly or more frequent basis with
representatives of the other party regarding its business, operations,
prospects, assets and financial condition and matters relating to the
completion of the transactions contemplated hereby.  As soon as reasonably
available, but in no event more than 45 days after the end of each calendar
quarter (other than the last quarter of each calendar year) ending after the
date of this Agreement, each party will deliver to the other party its
quarterly report on Form 10-Q (or Form 10-QSB) under the 1934 Act, and, as

    4.05.     ACCESS TO PROPERTIES AND RECORDS; CONFIDENTIALITY.

    (a)  THB shall permit PennFirst and its representatives reasonable

books of directors' and stockholders' meetings, organizational documents,
bylaws, material contracts and agreements, filings with any regulatory
authority, accountants' work papers, litigation files, plans affecting
employees, and any other business activities or prospects in which PennFirst
may have a reasonable interest.  Neither THB nor either of the THB
Subsidiaries shall be required to provide access to or to disclose
information where such access or disclosure would violate or prejudice the
rights of any customer or would contravene any law, rule, regulation, order
or judgment.  THB will use its best efforts to obtain waivers of any such
restriction and in any event make appropriate substitute disclosure
arrangements under circumstances in which the restrictions of the preceding
sentence apply.  THB and the THB Subsidiaries shall make their respective
directors, officers, employees and agents and authorized representatives
(including counsel and independent public accountants) available to confer
with PennFirst and its representatives, provided that such access shall be
reasonably related to the transactions contemplated hereby and not unduly
interfere with normal operations.  Similar access shall be provided by
PennFirst to THB and its representatives to the extent necessary to enable
THB to satisfy its due diligence obligations with respect to PennFirst.

    (b)  All information furnished previously in connection with the
transactions contemplated by this Agreement or pursuant hereto shall be
treated as the sole property of the party furnishing the information until
consummation of the Merger and, if such Merger shall not occur, the party
receiving the information shall, at the request of the party which furnished
such information, either return to the party which furnished such information
or destroy all documents or other materials containing, reflecting or
referring to such information; shall use its best effort to keep confidential
all such information; shall use such information only for the purpose of



                                     33

<PAGE>

consummating the transactions contemplated by this Agreement; and shall not
directly or indirectly use such information for any competitive or commercial
purposes.  The obligation to keep such information confidential shall
continue for three years from the date the proposed Merger is abandoned but
shall not apply to (i) any information which (A) the party receiving the
information can establish by convincing evidence was already in its
possession prior to the disclosure thereof to it by the party furnishing the
information; (B) was then generally known to the public; (C) became known to
the public through no fault of the party receiving the information; or (D)
was disclosed to the party receiving the information by a third party not
bound by an obligation of confidentiality; or (ii) disclosures pursuant to a
legal requirement or in accordance with an order of a court of competent
jurisdiction.

    (c)  From the date hereof until the earlier of the Effective Time or the
termination of this Agreement in accordance with the terms hereof, THB may
invite one person (to be designated by PennFirst) to attend all meetings of
the Board of Directors of THB and the THB Subsidiaries.

    4.06.     REGULATORY MATTERS.

    (a)  The parties hereto will cooperate with each other and use their

limitation the Form S-4 and the Joint Proxy Statement/Prospectus), to effect

approvals and authorizations of all third parties and governmental bodies
necessary to consummate the transactions contemplated by this Agreement as

in connection with the transactions contemplated by this Agreement.

    (b)  Each of the parties will furnish each other with all information
concerning themselves, their subsidiaries, directors, officers and

with the Merger and the other transactions, applications or filings
contemplated by this Agreement.

    (c)  Each of the parties will promptly furnish each other with copies of
written communications received by them or any of their respective
subsidiaries from, or delivered by any of the foregoing to, any governmental
body in connection with the Merger and the other transactions, applications

    4.07.     APPROVAL OF STOCKHOLDERS.  Each party will (a) take all steps
(including, without limitation, the preparation of the Form S-4 and Joint
Proxy Statement/Prospectus in accordance with all applicable requirements)
necessary to duly call, give notice of, convene and hold a meeting of its
stockholders as soon as reasonably practicable for the purposes of securing
the approval of such stockholders of this Agreement and the Agreement of

<PAGE>

to its stockholders the approval of this Agreement and the Agreement of 
Merger and the transactions contemplated hereby and thereby, and use its best 
efforts to obtain, as promptly as practicable, such approvals, and (c) 
cooperate and consult with the other party with respect to the foregoing 
matters.

herein provided, each of the parties hereto agrees to use its best efforts to
take, or cause to be taken, all reasonable action and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations to satisfy the conditions to closing contained herein and to
consummate and make effective the transactions contemplated by this Agreement
and the Agreement of Merger.  In case at any time after the Effective Time
any further action is necessary or desirable to carry out the purposes of
this Agreement, the proper officers and directors of each party to this
Agreement shall take all such necessary action.  Nothing in this section
shall be construed to require any party to participate in any threatened or
actual legal, administrative or other proceedings (other than proceedings,
actions or investigations to which it is a party or subject or threatened to
be made a party or subject) in connection with consummation of the
transactions contemplated by this Agreement unless such party shall consent
in advance and in writing to such participation and the other party agrees to
reimburse and indemnify such party for and against any and all costs and
damages related thereto.

    4.09.     DISCLOSURE SUPPLEMENTS.  From time to time prior to the
Effective Time, each party will promptly supplement or amend its respective
Disclosure Schedules delivered pursuant hereto with respect to any matter
hereafter arising which, if existing, occurring or known as of the date
hereof, would have been required to be set forth or described in such
Schedules or which is necessary to correct any information in such Schedules
which has been rendered inaccurate thereby.  No supplement or amendment to
such Schedules shall have any effect  for the purpose of determining
satisfaction of the conditions set forth in Article V or the compliance by
THB with the covenants set forth in Section 4.01 hereof. 

    4.10.     PUBLIC ANNOUNCEMENTS.  The parties hereto shall approve in
advance the substance of and cooperate with each other in the development and
distribution of all news releases and other public disclosures with respect
to this Agreement or any of the transactions contemplated hereby, except as
may be otherwise required by law or regulation and as to which the parties
releasing such information have used their best efforts to discuss with the
other parties in advance.

to consummate the transactions contemplated hereby cannot be fulfilled on or
prior to September 30, 1997 and that it will not waive that condition, it
will promptly notify the other party.  PennFirst and THB will promptly inform
the other of any facts applicable to them, or their respective directors or
officers, that would be likely to prevent or materially delay approval of the

    4.12.     CERTAIN POST-MERGER AGREEMENTS.

    The parties hereto agree to the following arrangements following the
Effective Time:

    (a)  OPERATIONS OF TROY HILL.  PennFirst shall maintain Troy Hill as a
separate subsidiary of PennFirst for a period of not less than one year from
the Effective Time.  Following such one-year period, PennFirst may, in its
sole discretion, determine to merge or consolidate Troy Hill with ESBB.

    (b)  BOARDS OF DIRECTORS OF PENNFIRST AND ESBB.  Effective as of the
Effective Time, the number of directors of both PennFirst and ESBB shall be
increased by one and PennFirst shall nominate and elect one current director
of THB (to be designated by PennFirst) as a director of each of PennFirst and
ESBB for a term of not less than three years.  In addition, in the event
PennFirst determines to merge or consolidate Troy Hill and ESBB on or after
one year from the Effective Time, two of the current directors of Troy Hill
who continue as directors of Troy Hill (but not PennFirst and ESBB) after the
Effective Time shall be elected to the Board of Directors of ESBB for a term
of not less than three years, and the current Chairman of the Board of Troy
Hill will be appointed to a newly created Troy Hill Advisory Board for a
period of not less than one year and shall receive advisory Board fees
therefor in an amount not less than $1,300 per month.  The provisions of this
Section 4.12(b) are intended to be for the benefit of, and shall be
enforceable by, current members of the Board of Directors of Troy Hill.

    (c)  BOARD OF DIRECTORS OF TROY HILL.  Effective as of the Effective
Time, Charlotte A. Zuschlag, the President and Chief Executive Officer of
PennFirst, shall be elected to the Board of Directors of Troy Hill.

    (d)  OFFICERS AND EMPLOYEES OF THB AND TROY HILL.  The employment of the
current President and Chief Executive Officer of THB and Troy Hill, Ellry N.
Davis, will be terminated effective as of the Effective Date, and Mr. Davis
will thereupon be entitled to, and PennFirst agrees to provide, the payments
and benefits reflected on THB Disclosure Schedule 2.13(a).  On or before the
Effective Date, in lieu of serving as a director of PennFirst, ESBB or Troy
Hill, PennFirst and Mr. Davis will negotiate and enter into a consulting
agreement on mutually acceptable terms.  PennFirst agrees to continue the
employment of all other personnel of THB and the THB Subsidiaries as of the
Effective Date, except in the event of good cause for termination, for a
period of not less than twelve (12) months subsequent to the Effective Date. 
After the Effective Time, Troy Hill shall not hire any additional employees
without the prior consent of PennFirst.

    (e)  EMPLOYEE BENEFIT PLANS.

    (1)  Subject to the provisions of this Section 4.12, all employees of
THB or the THB Subsidiaries immediately prior to the Effective Time who are
employed by PennFirst, ESBB or Troy Hill (the "Employers") immediately
following the Effective Time ("Transferred Employees") will be covered by
Employers' employee benefit plans on substantially the same basis as any
employee of the Employers in a comparable position.  Notwithstanding the



                                     36

<PAGE>

foregoing, PennFirst may determine to continue any of the THB benefit plans
for Transferred Employees in lieu of offering participation in the Employers'
benefit plans providing similar benefits (e.g., medical and hospitalization
benefits), to terminate any of THB's benefit plans, or to merge any such
benefit plans with the Employers' benefit plans, provided the result is the
provision of benefits to Transferred Employees that are substantially similar
to the benefits provided to the Employers' employees generally.  Except as
specifically provided in this Section 4.12 and as otherwise prohibited by
law, Transferred Employees' service with THB or Troy Hill shall be recognized
as service with the Employers for purposes of eligibility to participate and
vesting, if applicable (but not for purposes of benefit accrual) under the
Employers' benefit plans, subject to applicable break-in-service rules. 
PennFirst agrees that any pre-existing condition, limitation or exclusion in
its medical, long-term disability and life insurance plans shall not apply to
Transferred Employees or their covered dependents who are covered under a
medical or hospitalization indemnity plan maintained by THB or Troy Hill on
the Effective Time and who then change coverage to the Employers' medical or
hospitalization indemnity health plan at the time such Transferred Employees
are first given the option to enroll.  Notwithstanding anything herein to the
contrary, after the Effective Time, (x) any amendment to, or grant of
additional benefits under, any THB or Troy Hill benefit plan, including stock
based plans, which continues to exist subsequent to the Effective Time, shall
require the prior consent of the PennFirst, and (y) PennFirst may cause any
of the THB or Troy Hill benefit plans which continue to exist, including
stock based plans, to be amended in order to provide that employees of
PennFirst or ESBB may be participants in such plans.

    (2)  On or after the Effective Time, the THB employee stock ownership
plan ("THB ESOP") may, at PennFirst's discretion, be combined with the
PennFirst employee stock ownership plan ("PennFirst ESOP"); provided,
however, that prior to any such combination of the THB ESOP and the PennFirst
ESOP, the parties shall take all necessary action in order to amend the THB
ESOP in order to ensure that any such combination does not accelerate (other
than as required by law or regulation) or materially increase the benefits
available to any participant in the THB ESOP.  Notwithstanding anything
herein to the contrary, the parties hereto will take all necessary action to
amend the THB ESOP in order to provide that the Merger will not accelerate
(other than as required by law or regulation) or materially increase the
benefits available to any participant in the THB ESOP.

                                 CLOSING CONDITIONS

    5.01.     CONDITIONS TO THE PARTIES' OBLIGATIONS UNDER THIS AGREEMENT. 
The respective  obligations of the parties under this Agreement shall be
subject to the fulfillment at or  prior to the Effective Time of the
following conditions:

    (a)  All necessary regulatory or governmental approvals and consents
(including without limitation any required approval of the OTS required to
consummate the transactions contemplated hereby) shall have been obtained
without any term or condition which would 


                                     37

<PAGE>

materially impair the value of THB and the THB Subsidiaries to PennFirst; all 
conditions required to be satisfied prior to the Effective Time by the terms 
of such approvals and consents shall have been satisfied; and all waiting 
periods in respect thereof shall have expired.

    (b)  All corporate action necessary to authorize the execution and
delivery of this Agreement and consummation of the transactions contemplated
hereby and by the Agreement of Merger shall have been duly and validly taken
by PennFirst and THB, including approval by the requisite vote of the
stockholders of PennFirst and THB of this Agreement and the Agreement of
Merger.

    (c)  No order, judgment or decree shall be outstanding against a party
hereto or a third party that would have the effect of preventing completion
of the Merger; no suit, action or other proceeding shall be pending or
threatened by any governmental body in which it is sought to restrain or
prohibit the Merger; and no suit, action or other proceeding shall be pending
before any court or governmental agency in which it is sought to restrain or
prohibit the Merger or obtain other substantial monetary or other relief
against one or more of the parties hereto in connection with this Agreement
and which PennFirst or THB determines in good faith, based upon the advice of
their respective counsel, makes it inadvisable to proceed with the Merger
because any such suit, action or proceeding has a significant potential to be
resolved in such a way as to deprive the party electing not to proceed of any
of the material benefits to it of the Merger.

    (d)  The Form S-4 shall have become effective under the 1933 Act, and
PennFirst shall have received all state securities laws or "blue sky" permits
and other authorizations or there shall be exemptions from registration
requirements necessary to issue the PennFirst Common Stock in connection with
the Merger, and neither the Form S-4 nor any such permit, authorization or
exemption shall be subject to a stop order or threatened stop order by the
Commission or any state securities authority.

    (e)  The parties shall have received, in form and substance reasonably
satisfactory to them, an opinion of Elias, Matz, Tiernan & Herrick to the
effect that, for federal income tax purposes, the Merger will qualify as a
"reorganization" under Section 368(a) of the Code; no taxable gain will be
recognized by PennFirst or THB (i) upon the transfer of THB's assets to
PennFirst in exchange for PennFirst Common Stock, cash and the assumption of
THB's liabilities or (ii) upon the distribution of such PennFirst Common
Stock and cash to THB stockholders.

    5.02.     CONDITIONS TO THE OBLIGATIONS OF PENNFIRST UNDER THIS
AGREEMENT.  The obligations of PennFirst under this Agreement shall be
further subject to the satisfaction, at or prior to the Effective Time, of
the following conditions, any one or more of which may be waived by
PennFirst:

    (a)  Each of the obligations of THB required to be performed by it at or
prior to the Closing pursuant to the terms of this Agreement shall have been
duly performed and complied with in all material respects and the
representations and warranties of THB contained in this 


                                     38

<PAGE>

Agreement shall have been true and correct as of the date hereof and as of 
the Effective Time as though made at and as of the Effective Time, except (i) 
as to any representation or warranty which specifically relates to an earlier 
date or (ii) where the facts which caused the failure of any representation 
or warranty to be so true and correct would not, either individually or in 
the aggregate, constitute a material adverse change in the business, 
operations, assets or financial condition of THB and the THB Subsidiaries 
taken as a whole, and PennFirst shall have received a certificate to that 
effect signed by the President and Chief Executive Officer of THB.

    (b)  All permits, consents, waivers, clearances, approvals and
authorizations of all regulatory or governmental authorities or third parties
which are necessary in connection with the consummation of the Merger shall
have been obtained, and none of such permits, consents, waivers, clearances,
approvals and authorizations shall contain any term or condition which would
materially impair the value of THB and the THB Subsidiaries to PennFirst.

    (c)  PennFirst shall have received, in form and substance satisfactory
to it, a letter dated the date of the Closing, from KPMG Peat Marwick to the
effect that the Merger will qualify for purchase accounting treatment.

    (d)  Holders of THB Common Stock who dissent from the Merger pursuant to
Chapter 15, Subchapter D of the PBCL by meeting the requirements set forth in
the PBCL shall not hold more than 15% of the THB Common Stock immediately
prior to the Effective Time.

    (e)  Each stockholder of THB who is a THB Affiliate shall have executed
and delivered a commitment and undertaking to the effect that (i) such
stockholder will dispose of the shares of PennFirst Common Stock received by
him in connection with the Merger only in accordance with the provisions of
paragraph (d) of Rule 145 under the 1933 Act; (ii) such stockholder will not
dispose of any of such shares until PennFirst has received an opinion of
counsel acceptable to it that such proposed disposition is in compliance with
the provisions of paragraph (d) of Rule 145 under the 1933 Act, which opinion
shall be rendered promptly following counsel's receipt of such stockholder's
written notice of its intention to sell shares of PennFirst Common Stock; and
(iii) the certificates representing said shares may bear a legend referring
to the foregoing restrictions.

    (f)  THB shall have furnished PennFirst with such certificates of its
officers or others and such other documents to evidence fulfillment of the
conditions set forth in this Section 5.02 as PennFirst may reasonably
request.

    5.03.     CONDITIONS TO THE OBLIGATIONS OF THB UNDER THIS AGREEMENT. The 
obligations of THB under this Agreement shall be further subject to the 
satisfaction, at or prior to the Effective  Time, of the following 
conditions, any one or more of which may be waived by THB:

    (a)  Each of the obligations of PennFirst required to be performed by it
at or prior to the Closing pursuant to the terms of this Agreement shall have
been duly performed and complied with in all material respects and the
representations and warranties of PennFirst contained in this Agreement shall
have been true and correct as of the date hereof and as of the



                                     39

<PAGE>

Effective Time as though made at and as of the Effective Time, except (i) as 
to any representation or warranty which specifically relates to an earlier 
date or (ii) where the facts which caused the failure of any representation 
or warranty to be so true and correct would not, either individually or in 
the aggregate, constitute a material adverse change in the business, 
operations, assets or financial condition of PennFirst and the PennFirst 
Subsidiaries taken as a whole, and THB shall have received a certificate to 
that effect signed by the President and Chief Executive Officer of PennFirst.

    (b)  PennFirst shall have furnished THB with such certificates of its
officers or others and such other documents to evidence fulfillment of the
conditions set forth in this Section 5.03 as THB may reasonably request.

                      TERMINATION, AMENDMENT AND WAIVER, ETC.

    6.01.     TERMINATION.  This Agreement may be terminated at any time
prior to the Effective Time, whether before or after approval of this
Agreement and the Agreement of Merger by the stockholders of PennFirst and/or
THB:

    (a)  by mutual written consent of the parties hereto;

    (b)  by PennFirst or THB (i) if the Effective Time shall not have
occurred on or prior to September 30, 1997 or (ii) if a vote of the
stockholders of PennFirst or THB is taken and either of such stockholders
fails to approve this Agreement and the Agreement of Merger at the meetings
of stockholders (or any adjournment thereof) of PennFirst and THB
contemplated by Section 4.07 hereof; unless in each case the failure of such
occurrence shall be due to the failure of the party seeking to terminate this
Agreement to perform or observe its agreements set forth herein to be
performed or observed by such party at or before the Effective Time;

    (c)  by PennFirst or THB upon written notice to the other 30 or more
days after the date upon which any application for a regulatory or
governmental approval necessary to consummate the Merger and the other
transactions contemplated hereby shall have been denied or withdrawn at the
request or recommendation of the applicable regulatory agency or governmental
authority, unless within such 30-day period a petition for rehearing or an
amended application is filed or noticed, or 30 or more days after any
petition for rehearing or amended application is denied;

    (d)  by PennFirst in writing if THB has, or by THB in writing if
PennFirst has, breached (i) any covenant or undertaking contained herein or
in the Agreement of Merger, or (ii) any representation or warranty contained
herein, which breach would have a material adverse effect on the business,
operations, assets or financial condition of THB and the THB Subsidiaries or
PennFirst and the PennFirst Subsidiaries, as applicable, taken as a whole, or
upon the consummation of the transactions contemplated hereby, in any case if
such breach has not been 



                                     40

<PAGE>

cured by the earlier of 30 days after the date on which written notice of 
such breach is given to the party committing such breach or the Effective 
Time; provided that it is understood and agreed that either party may 
terminate this Agreement on the basis of any such material breach of any 
representation or warranty contained herein, notwithstanding any 
qualification therein relating to the knowledge of the other party;

    (e)  by PennFirst or THB in writing, if any of the applications for
prior approval referred to in Section 4.06 hereof are denied or are approved
contingent upon the satisfaction of any condition or requirement which, in
the reasonable opinion of the Board of Directors of PennFirst, would
materially impair the value of THB and the THB Subsidiaries to PennFirst, and
the time period for appeals and requests for reconsideration has run.


    6.02.     EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either PennFirst or THB as provided above, this Agreement shall
forthwith become void (other than Sections 4.05(b) and 7.01 hereof, which
shall remain in full force and effect) and there shall be no further
liability on the part of the parties or their respective officers or
directors except for the liability of the parties under Sections 4.05(b) and
7.01 hereof and except for liability for any breach of this Agreement.

    6.03.     AMENDMENT, EXTENSION AND WAIVER.  Subject to applicable law,
at any time prior to the consummation of the Merger, whether before or after
approval thereof by the stockholders of PennFirst and/or THB, the parties may
(a) amend this Agreement and the Agreement of Merger, (b) extend the time for
the performance of any of the obligations or other acts of the other parties
hereto, (c) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto, or (d) waive
compliance with any of the agreements or conditions contained herein;
provided, however, that after any approval of the Merger by the stockholders
of PennFirst and/or THB, there may not be, without further approval of such
stockholders, any amendment or waiver of this Agreement or the Agreement of
Merger which modifies either the amount or the form of the Merger
Consideration to be delivered to stockholders of THB.  This Agreement and the
Agreement of Merger may not be amended except by an instrument in writing
signed on behalf of each of the parties hereto.  Any agreement on the part of
a party hereto to any extension or waiver shall be valid only if set forth in
an instrument in writing signed on behalf of such party, but such waiver or
failure to insist on strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

rights hereunder; provided, further, however, that in the event that, (x)
PennFirst's Board of Directors fails to recommend to its stockholders the

fail to approve this Agreement and the Agreement of Merger at a duly held
meeting of such stockholders or at any adjournment or postponement thereof or
(y) PennFirst fails to duly hold a meeting of its stockholders for the
purpose of voting on this Agreement and the Agreement of Merger, then
PennFirst will promptly reimburse THB for its out-of-pocket costs and

all and every other interest shall be thereafter as effectually the property
of the Surviving Corporation as they were of, respectively, THB and
PennFirst, and the title to any real estate vested by deed or otherwise,
under the laws of the Commonwealth of Pennsylvania or elsewhere in either THB
or PennFirst shall not revert or be in any way impaired by reason of the
Merger, but all rights of creditors and all liens upon any property of either
of THB or PennFirst shall be preserved unimpaired, and all debts, liabilities
and duties of THB and PennFirst shall thenceforth attach to the Surviving
Corporation and may be enforced against it to the same extent as if said

     3.1  CONVERSION OF THB COMMON STOCK AND OPTIONS TO PURCHASE THB COMMON
          STOCK.

     (a)  Subject to Section 3.2 hereof, each share of THB Common Stock
outstanding immediately prior to the Effective Time, other than (i) shares
held by THB (including Treasury shares) or PennFirst or any of their
respective wholly owned subsidiaries and (ii) THB Dissenting Shares (as
hereinafter defined), shall be converted into the number of shares of
PennFirst Common Stock equal to the Exchange Ratio (as defined in the
Reorganization Agreement) or $21.15 in cash in accordance with the terms of
Section 1.03 of the Reorganization Agreement.

     (b)  Notwithstanding any other provision hereof, no fractional shares of
PennFirst Common Stock shall be issued to holders of THB Common Stock.  In
lieu thereof, each holder of shares of THB Common Stock entitled to a
fraction of a share of PennFirst Common Stock shall, at the time of surrender
of the certificate or certificates representing such holder's shares, receive
an amount of cash in accordance with the terms of Section 1.05 of the
Reorganization Agreement.  No such holder shall be entitled to dividends,
voting rights or any other rights in respect of any fractional share.

     (c)  At or immediately prior to the Effective Time, each option to
purchase THB Common Stock issued pursuant to THB's 1994 Stock Option Plan
shall be cancelled, and each holder of any such option, whether or not then
vested or exercisable, shall be entitled to receive from PennFirst or THB
either a new option to acquire shares of PennFirst Common Stock or a cash
amount determined in accordance with Section 1.06 of the Reorganization
Agreement.  The payment of the consideration referred to in this Section
3.1(c) to holders of options to purchase THB Common Stock shall be subject to
the execution by any such holder of such instruments of cancellation as
PennFirst may reasonably deem appropriate.

     3.2  EXCHANGE OF CERTIFICATES FOR STOCK AND/OR CASH.

     After the Effective Time, each holder of a certificate for theretofore
outstanding shares of THB Common Stock, shall be surrendered and exchanged
for cash or stock consideration in the manner provided in Section 1.04 of the
Reorganization Agreement.

     3.3  DISSENTING SHARES.  Notwithstanding anything in this Agreement of
Merger to the contrary, shares of THB Common Stock which are outstanding
immediately prior to the Effective Time and which are held by stockholders
(other than PennFirst or any wholly-owned subsidiary thereof) who shall not
have voted such shares in favor of the Agreement and this Agreement of Merger
and who shall have satisfied all of the applicable requirements of Chapter
15, Subchapter D of the PBCL ("THB Dissenting Shares"), shall not be
converted into the right to receive, or be exchangeable for, shares of
PennFirst Common Stock or cash as set forth in Section 3.1 hereof, but the
holders thereof shall be entitled to payment of the fair value of such shares
in accordance with said section of the PBCL, subject to the procedures and
the conditions specified in such provision of the PBCL, unless and until such
holders shall have failed to perfect or shall have effectively withdrawn or
lost their right to appraisal and payment under such law.  If any such holder
shall have failed to perfect or shall have effectively withdrawn or lost such
right of appraisal, the shares of THB Common Stock held by such holder shall
thereupon be deemed to have been converted into the right to receive, or be
exchangeable at the Effective Time for, cash as provided in 1.08 of the
Reorganization Agreement.  PennFirst hereby agrees to make, or cause to be
made, payment in cash for any Dissenting Shares.

     3.4  PENNFIRST COMMON STOCK.  Each share of PennFirst Common Stock
issued and outstanding immediately prior to the Effective Time shall, on and
after the Effective Time, continue to be issued and outstanding as an
identical share of PennFirst Common Stock.

                                   MISCELLANEOUS

     4.1  CONDITIONS PRECEDENT.  The respective obligations of each party
under this Agreement of Merger shall be subject to the satisfaction, or
waiver by the party permitted to do so, of the conditions set forth in
Article V of the Reorganization Agreement.

     4.2  TERMINATION.  This Agreement of Merger shall be terminated
automatically without further act or deed of either of the parties hereto in
the event of the termination of the Reorganization Agreement in accordance
with Section 6.01 thereof.

     4.3  AMENDMENTS.  To the extent permitted by the PBCL, this Agreement of
Merger may be amended by a subsequent writing signed by each of the parties
hereto upon the approval of the Board of Directors of each of the parties
hereto; provided, however, that the provisions of Article III of this
Agreement of Merger relating to the consideration to be paid for the shares
of THB Common Stock shall not be amended after either of the Stockholder
Meetings so as to modify either the amount or the form of such consideration
or to otherwise materially adversely affect the shareholders of PennFirst or
THB without the approval of the stockholders of PennFirst and THB who are so
affected.

     4.4  SUCCESSORS.  This Agreement of Merger shall be binding on the
successors of PennFirst and THB.

                           STOCK OPTION AGREEMENT


    STOCK OPTION AGREEMENT, dated as of September 16, 1996, by and between 
PennFirst Bancorp, Inc. ("PennFirst"), a Pennsylvania corporation, and Troy 
Hill Bancorp, Inc. ("THB"), a Pennsylvania corporation (the "Agreement").


                                 WITNESSETH

    WHEREAS, PennFirst and THB have entered into an Agreement and Plan of
Reorganization and related Agreement of Merger, each dated as of September
16, 1996 (collectively, the "Reorganization Agreement");

    WHEREAS, PennFirst has requested the execution of this Agreement by THB
in order to increase the likelihood that the transactions contemplated by
the Reorganization Agreement will be consummated in accordance with its
terms and as a condition to PennFirst's obligation to complete the
transactions contemplated by the Reorganization Agreement and, in
consideration for such execution, THB has agreed to issue to PennFirst an
option entitling PennFirst to purchase shares of its common stock upon the
terms and subject to the conditions set forth herein; and

    NOW, THEREFORE, in consideration of the execution of the Reorganization
Agreement and the premises therein and herein contained, the parties agree
as follows:

    1.   GRANT OF OPTION.  Subject to the terms and conditions hereof, THB
irrevocably grants to PennFirst as of September 16, 1996 the option
("Option") to purchase at one time or from time to time an aggregate of
213,000 shares of common stock, par value $.01 per share, of THB ("Common
Stock") at a price per share equal to $15.75 (the price per share is
referred to below as the "Purchase Price" and the price when used with
respect to a number of shares is referred to below as the "aggregate
Purchase Price" for such shares).  As used in this Agreement, the term
"Shares" means the shares of Common Stock subject to the Option.

    2.   EXERCISE OF OPTION.

    (a)  Subject to the terms and conditions hereof, PennFirst may exercise 
the Option, in whole at any time or in part from time to time, to the extent 
not previously exercised, if a Purchase Event (as defined below) shall have 
occurred and be continuing, provided that to the extent the Option shall not 
have been exercised, it shall terminate and be of no further effect, except 
as to notices of exercise given prior thereto, on the Termination Date, which 
shall be the date on which occurs the earliest of (i) immediately prior to 
the Effective Time, as defined in Section 1.02 of the Reorganization 
Agreement, (ii) twelve (12) months after the first occurrence of a Purchase 
Event, (iii) twelve (12) months following a termination of the Reorganization 
Agreement by PennFirst pursuant to Section 6.01(d) thereof prior to the 
occurrence of a Purchase

<PAGE>

Event; and (iv) a termination of the Reorganization Agreement in accordance 
with its terms (other than by PennFirst pursuant to Section 6.01(d) thereof) 
prior to the occurrence of a Purchase Event, provided, however, that any 
purchase of shares upon exercise of the Option shall be subject to compliance 
with applicable laws and regulations.

    (b)  As used herein, a "Purchase Event" shall mean any of the following
events or transactions occurring after the date hereof:

         (i)   THB or any of its subsidiaries shall have entered into an
    agreement with any person (other than PennFirst or any subsidiary
    thereof) (A) to merge, consolidate or enter into any similar
    transaction with such person, (B) for the disposition, by sale, lease,
    exchange or otherwise, of all or substantially all of the consolidated
    assets or deposits of THB or any of its subsidiaries or (C) for the
    issuance, sale or other disposition (including by way of merger,
    consolidation, share exchange or any similar transaction) of securities
    (or an option or right to acquire such securities) representing 15% or
    more of the voting power of THB or any of its subsidiaries;

         (ii)  any person (other than PennFirst or any subsidiary thereof)
    shall have acquired beneficial ownership of, or any group of persons
    shall have been formed which beneficially owns, 15% or more of the then
    outstanding Common Stock (any of the foregoing in Section 2(b)(i) or
    (ii) is hereinafter referred to as an "Acquisition Transaction");

         (iii) any person (other than PennFirst or any subsidiary thereof) 
    shall have (A) commenced a tender offer or filed a registration statement 
    under the Securities Act of 1933, as amended ("Securities Act"), with 
    respect to an exchange offer to purchase or otherwise acquire control of 
    15% or more of the then outstanding shares of Common Stock (such offers 
    being referred to herein as a "Tender Offer" and an "Exchange Offer," 
    respectively); or 

         (iv)  the holders of the outstanding Common Stock shall not have
    approved the Reorganization Agreement (including the related Agreement
    of Merger) at the meeting of such holders called for such purpose
    pursuant to the Reorganization Agreement, such meeting shall not have
    been held or shall have been cancelled prior to the termination of the
    Reorganization Agreement in accordance with its terms, or THB's Board
    of Directors shall have withdrawn or modified in a manner which is
    adverse to PennFirst the recommendation of THB's Board of Directors
    with respect to the Reorganization Agreement and the Agreement of
    Merger, in each case after it shall have been publicly announced that
    any person (other than PennFirst or any subsidiary thereof) shall have
    (A) commenced a Tender Offer or filed a registration statement under
    the Securities Act with respect to an Exchange Offer, (B) made, or
    disclosed an intention to make, a proposal to engage in an Acquisition
    Transaction, (C) filed an application (or given notice), whether in
    draft or final form, under the Bank Holding Company Act of 1956, the
    Home Owners' Loan Act, the Bank Merger Act or the Change in Bank
    Control Act of 1978, for approval

                                  2


<PAGE>

    to engage in an Acquisition Transaction or (D) any person shall have 
    solicited proxies in a proxy solicitation subject to Regulation 14A under
    the Securities Exchange Act of 1934, as amended ("Exchange Act"), in 
    opposition to approval of the Reorganization Agreement by THB's 
    stockholders.

    (c)  As used in this Agreement, (i) "beneficial ownership," "person"
and "group of persons" shall have the meanings conferred thereon by Section
13(d) of the Exchange Act and the regulations promulgated thereunder and
(ii) "commenced" shall have the meaning conferred thereon by Rule 14d-2
under the Exchange Act.

    (d)  THB shall promptly give written notice to PennFirst of the
occurrence of a Purchase Event known to THB.  However, the giving of such
notice by THB shall not be a condition to the right of PennFirst to exercise
the Option. If more than one transaction or event giving rise to a Purchase
Event is undertaken or effected, then all such transactions shall give rise
to only one Purchase Event, which Purchase Event shall be deemed continuing
for all purposes hereunder until all such transactions or events are
abandoned.

    (e)  Notwithstanding the foregoing, THB shall not be obligated to issue
Shares upon exercise of the Option (i) in the absence of any required
governmental, regulatory or stockholder approval or consent necessary for
THB to issue the Shares or for PennFirst to exercise the Option or prior to
the expiration or termination of any waiting period required by law, or (ii)
so long as any injunction or other order, decree or ruling issued by any
federal or state court of competent jurisdiction is in effect which
prohibits the sale or delivery of the Shares.  If the Option is otherwise
exercisable but cannot be exercised prior to termination as specified in
Section 2(a) hereof solely because of any injunction, order or similar
restraint issued by a court of competent jurisdiction, the Option shall
continue and will expire on the twentieth business day after such
injunction, order or restraint shall have been dissolved or when such
injunction, order or restraint shall have become permanent and no longer
subject to appeal, as the case may be.

    3.   NOTICE OF EXERCISE; PAYMENT AND DELIVERY OF SHARES.

    (a)  In the event that PennFirst desires to exercise the Option,
PennFirst shall send a written notice (the date of which being herein
referred to as the "Notice Date") to THB specifying the total number of
Shares it will purchase and a place and date for the closing of such
purchase, which date shall be not later than 60 calendar days nor earlier
than three business days from the date such notice is given, unless
additional time is needed to give notification to or to obtain approval from
any governmental or regulatory authority and, if so required, three business
days from the date on which the required notification period has expired or
been terminated or such approval has been obtained and any requisite waiting
period with respect thereto shall have passed.

    (b)  At any closing hereunder, (a)(i) PennFirst shall make payment to THB 
of the aggregate Purchase Price for the Shares to be purchased by delivery to 
THB of a certified, cashier's or bank check payable to the order of THB in 
such amount or, if mutually agreed, by 

                                  3

<PAGE>

wire transfer of funds in such amount to an account designated in writing by 
THB, or (ii) if requested by PennFirst, in lieu of the payment set forth in 
(a)(i) above, THB shall issue to PennFirst a number of whole Shares 
determined by (A) multiplying the excess, if any, of the closing price of the 
Common Stock on the Notice Date over the Purchase Price by the number of 
Shares with respect to which the Option is being exercised, and (B) dividing 
such product by the Purchase Price; and (b) THB shall deliver to PennFirst a 
certificate or certificates representing the Shares so purchased, registered 
in the name of PennFirst or its designee.  THB shall pay any and all federal, 
state and local taxes, or other charges that may be imposed upon PennFirst in 
connection with the preparation, issuance and delivery of stock certificates 
hereunder.

    4.   REPRESENTATIONS AND WARRANTIES OF THB.  THB hereby represents and
warrants to PennFirst as follows:

    (a)  This Agreement has been duly authorized, executed and delivered by
THB and constitutes a valid and binding agreement of THB, enforceable
against THB in accordance with its terms, except to the extent that the
obligations of THB set forth in Section 8(a) and (d) hereof may be
unenforceable under applicable federal and state securities laws.

    (b)  THB has taken all necessary corporate and other action (excluding
any required governmental or stockholder approvals) to authorize and reserve
and to permit it to issue, and at all times from the date hereof until such
time as the obligation to deliver Shares upon the exercise of the Option
terminates, will have reserved for issuance, upon any exercise of the
Option, the number of Shares subject to the Option (less the number of
Shares previously issued upon any partial exercise of the Option or as to
which the Option may no longer be exercised).  All of the Shares to be
issued pursuant to the Option are duly authorized and, upon issuance and
delivery thereof pursuant to this Agreement, will be duly and validly
issued, fully paid and nonassessable, free and clear of all claims, liens,
charges, encumbrances and security interests, and will not have been issued
in violation of, and will not be subject to, any preemptive rights of any
stockholders of THB.

    (c)  The execution, delivery and performance by THB of this Agreement
and the consummation of the transactions contemplated hereby (excluding any
required governmental approvals) do not contravene, or constitute a default
under, (i) the Articles of Incorporation or Bylaws of THB or (ii) any
agreement, instrument, judgment, decree, order, statute, rule or
governmental regulation binding upon THB or any of its subsidiaries.

    5.   REPRESENTATIONS AND WARRANTIES OF PENNFIRST.  PennFirst hereby
represents and warrants to THB as follows:

    (a)  This Agreement has been duly authorized, executed and delivered by
PennFirst and constitutes a valid and binding agreement of PennFirst,
enforceable against PennFirst in accordance with its terms, except to the
extent that the obligations of PennFirst set forth in Section 8(b) and (d)
hereof may be unenforceable under applicable federal and state securities
laws.

                                  4


<PAGE>

    (b)  PennFirst is acquiring the Option for the purpose set forth in the
second Whereas clause of this Agreement and hereby acknowledges that (i) the
Option has not been, and the Shares may not be, registered under the
Securities Act or any other applicable securities registration requirements
and (ii) the Option and the Shares may not be transferred except in
compliance with applicable registration requirements or an available
exemption therefrom.

    6.   ADJUSTMENT UPON CHANGE IN CAPITALIZATION, ETC.  In the event of
any change in the Common Stock by reason of stock dividends, stock splits,
mergers, consolidations, recapitalizations, combinations, conversions,
exchanges of shares, extraordinary or liquidating dividends, or other
changes in the corporate or capital structure of THB which would have the
effect of diluting or changing PennFirst's rights hereunder, the number and
kind of shares or securities subject to the Option and the Purchase Price
(but not the aggregate Purchase Price of the Shares) shall be appropriately
and equitably adjusted so that PennFirst shall receive upon exercise of the
Option the number and class of shares or other securities or property that
PennFirst would have received in respect of the Shares that could have been
purchased upon exercise of the Option if the Option could have been and had
been exercised immediately prior to such event or the record date therefor,
as applicable.  In the event that after the date hereof THB issues any
additional shares of Common Stock other than pursuant to any event described
in the preceding sentence or pursuant to the exercise of the Option, the
number of shares of Common Stock which can be purchased pursuant to the
Option shall be increased by an amount so that after such issuance the
number of shares of Common Stock subject to the Option, less any shares
previously acquired upon exercise of the Option, shall equal (a) 20.0% of
the number of shares of Common Stock then issued and outstanding minus (b)
one share, without giving effect to any shares which may be issued pursuant
to the Option.  THB shall take such steps in connection with any
consolidation, merger, liquidation or other such action as may be necessary
to ensure that the provisions hereof shall thereafter apply as nearly as
possible to any securities or property thereafter deliverable upon exercise
of the Option.  Nothing contained in this Section 6 shall be deemed to
authorize THB to effect any of the changes contemplated by this Section 6 in
breach of the provisions of the Reorganization Agreement.

    7.   REGISTRATION OF THE SHARES.

    (a)  If PennFirst requests THB in writing to register under the
Securities Act or any other applicable securities registration requirements
Shares which have been purchased by PennFirst hereunder, THB will use its
best efforts to cause the Shares so specified in such request to be
registered as soon as practicable so as to permit the sale or other
distribution by PennFirst of such Shares (and to keep such registration in
effect for a period of at least 180 days) and in connection therewith shall
prepare and file as promptly as reasonably possible (but in no event later
than 45 days from receipt of PennFirst's request) a registration statement
under the Securities Act to effect such registration on an appropriate form,
which would permit the sale of the Shares by PennFirst in the manner
specified by PennFirst in its request.  In connection with such
registration, THB shall use its best efforts to cause to be delivered to
PennFirst (and any other holder whose Shares are the subject of such
registration) such certificates, opinions, accountants' letters and other
documents as PennFirst (or any such other holder) shall reasonably 

                                  5

<PAGE>

request and are customarily rendered in connection with the registration of 
securities under the Securities Act.  PennFirst shall provide all information 
reasonably requested by THB for inclusion in any documents to be prepared 
hereunder.  All expenses incurred by THB in complying with the provisions of 
this Section 7, including, without limitation, all registration and filing 
fees, printing expenses, fees and disbursements of counsel for THB and blue 
sky fees and expenses shall be paid by THB. Underwriting discounts and 
commissions to brokers and dealers relating to the Shares, fees and 
disbursements of counsel to PennFirst and any other expenses incurred by 
PennFirst in connection with such registration shall be borne by PennFirst.  
THB shall not be obligated to make effective more than two registration 
statements pursuant to this Section 7(a).

    (b)  THB shall notify PennFirst in writing not less than ten business
days prior to filing a registration statement under the Securities Act with
respect to any Common Stock (other than a filing on Form S-4 or Form S-8) of
THB's intention so to file.  If PennFirst wishes to have any portion of its
Shares purchased hereunder included in such registration statement, it shall
advise THB in writing to that effect within five business days following
receipt of such notice from THB pursuant to the preceding sentence, and THB
will thereupon include the number of shares indicated by PennFirst under
such registration statement, provided, however, that if the managing
underwriter determines and advises THB and PennFirst in writing that the
inclusion in the registration statement of the number of shares indicated by
PennFirst would interfere with the successful marketing of the Common Stock
proposed to be registered and sold by THB, then the number of shares
indicated by PennFirst to be included in the underwriting shall be reduced
or eliminated pro rata among all holders of shares of Common Stock
requesting such registration, and further provided, however, that nothing
herein shall prevent THB from, at any time, abandoning or delaying any
registration.

    (c)  The rights provided under this Section 7 shall expire upon the
third annual anniversary of the first acquisition of Shares by PennFirst
hereunder.

    8.   INDEMNIFICATION.

    (a)  In connection with any registration under the provisions of
Section 7 hereof, THB shall indemnify and hold harmless PennFirst and any
underwriter (as defined in the Securities Act) for PennFirst and each person
who controls PennFirst or such underwriter within the meaning of the
Securities Act, from and against any and all loss, damage, liability, cost
and expense to which PennFirst or any such underwriter or controlling person
may become subject under the Securities Act or otherwise, insofar as such
losses, damages, liabilities, costs or expenses are caused by or arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in such registration statement, any preliminary or
final offering prospectus contained therein or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission
to state therein a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances in which they
were made, not misleading; provided, however, that THB will not be liable in
any such case to the extent that any such loss, damage, liability, cost or
expense arises out of or is based upon an untrue statement or omission so
made in conformity with information furnished by PennFirst,

                                  6

<PAGE>

such underwriter or such controlling persons in writing specifically for use 
in the preparation thereof.

    (b)  PennFirst will indemnify and hold harmless THB, any underwriter
for THB and each person who controls THB or such underwriter within the
meaning of the Securities Act, from and against any and all loss, damage,
liability, cost and expense to which THB or any such underwriter or
controlling person may become subject under the Securities Act or otherwise,
insofar as such losses, damages, liabilities, costs or expenses are caused
by or arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in such registration statement, any
preliminary or final offering prospectus contained therein or any amendment
or supplement thereto, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, in each case to the
extent, but only to the extent, that such untrue statement or omission was
so made in conformity with information furnished by PennFirst in writing
specifically for use in the preparation thereof.

    (c)  Promptly after receipt by an indemnified party pursuant to the
provisions of Section 8(a) or (b) of notice of the commencement of any
action involving the subject matter of the foregoing indemnity provisions,
such indemnified party will, if a claim in respect thereof is to be made
against the indemnifying party pursuant to the provisions of Section 8(a) or
(b), promptly notify the indemnifying party of the commencement thereof;
except to the extent of any actual prejudice to the indemnifying party, the
omission to so notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise hereunder. 
In case such action is brought against any indemnified party and it notifies
the indemnifying party of the commencement thereof, the indemnifying party
shall have the right to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified
party; provided, however, that if the defendants in any action include both
the indemnified party and the indemnifying party and there is a conflict of
interests which would prevent counsel for the indemnifying party from also
representing the indemnified party, the indemnified party or parties shall
have the right to select one separate counsel to participate in the defense
of such action on behalf of such indemnified party or parties.  After notice
from the indemnifying party to such indemnified party of its election so to
assume the defense thereof, the indemnifying party will not be liable to
such indemnified party pursuant to the provisions of Section 8(a) or (b) for
any legal or other expenses subsequently incurred by such indemnified party
in connection with the defense thereof other than reasonable costs of
investigation, unless (i) the indemnified party shall have employed counsel
in accordance with the provisions of the preceding sentence, (ii) the
indemnifying party shall not have employed counsel reasonably satisfactory
to the indemnified party to represent the indemnified party within a
reasonable time after the notice of the commencement of the action, or (iii)
the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party.

    (d)  If recovery is not available under the foregoing indemnification
provisions, for any reason other than as expressly specified therein, the
parties entitled to indemnification by the terms thereof shall be entitled
to contribution to liabilities and expenses, except to the extent that
contribution is not permitted under Section 11(f) of the Securities Act.  In
determining the amount of contribution to which the respective parties are
entitled, there shall be considered the parties' relative fault, knowledge
and access to information concerning the matter with respect to which the
claim was asserted, the opportunity to correct and/or prevent any statement
or omission, and any other equitable considerations appropriate under the
circumstances.

    9.   QUOTATION.  If the Common Stock or any other securities to be 
acquired upon exercise of the Option are then authorized for quotation or 
trading or listing on the Nasdaq National Market System ("Nasdaq NMS") or any 
securities exchange, THB, upon the request of PennFirst after the occurrence 
of a Purchase Event, will promptly file an application, if required, to 
authorize for quotation or trading or listing the Shares of Common Stock (or 
other securities to be acquired upon exercise of the Option pursuant to the 
terms of Section 6 hereof) on the Nasdaq NMS or such other securities 
exchange and will use its best efforts to obtain approval, if required, of 
such quotation or listing as soon as practicable.

    10.  FURTHER ASSURANCES.  THB agrees to execute and deliver such
documents and instruments and take such further actions as may be necessary
or appropriate or as PennFirst may reasonably request in order to ensure
that PennFirst receives the full benefits of this Agreement (including,
without limitation, the prompt filing of any required notice or application
for approval with any applicable federal or state regulatory agency and the
expeditious processing of the same).  Prior to the Termination Date, THB
will refrain from taking any action which would have the effect of
preventing or interfering with the delivery by THB of the Shares (or other
securities deliverable pursuant to Section 6 hereof) to PennFirst upon any
exercise of the Option or from otherwise performing its obligations under
this Agreement.

    11.  REMEDIES.  The parties agree that PennFirst would be irreparably
damaged if for any reason THB failed to issue any of the Shares (or other
securities deliverable pursuant to Section 6 hereof) upon exercise of the
Option or to perform any of its other obligations under this Agreement, and
that PennFirst would not have an adequate remedy at law in such event. 
Accordingly, PennFirst shall be entitled to specific performance and
injunctive and other equitable relief to enforce the performance of this
Agreement by THB.  This provision is without prejudice to any other rights
that PennFirst may have against THB for any failure to perform its
obligations under this Agreement.

    12.  MISCELLANEOUS.

    (a)  Expenses.  Except as otherwise provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or
on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own financial consultants, investment
bankers, accountants and counsel.

obligations hereunder in whole or in part without such consent.  In the case
of any permitted sale, transfer, assignment or disposition in part of this
Option, THB shall do all things necessary to facilitate the same and the

hereof) any rights or remedies of any nature whatsoever under or by any
reason of this Agreement.

     13.  ENTIRE AGREEMENT.  This Agreement, including the documents and

September 16, 1996


Board of Directors
Troy Hill Bancorp, Inc
1706 Lowrie Street
Pittsburgh, Pennsylvania 15212


Dear Gentlemen:

You have requested our opinion as an independent investment banking firm
regarding the fairness, from a financial point of view, to the shareholders
of Troy Hill Bancorp, Inc. ("THBC"), of the consideration to be received by
such shareholders in the merger (the "Merger") between THBC and PennFirst
Bancorp, Inc., ("PWBC").  We have not been requested to opine as to, and our
opinion does not in any matter address, THBC's underlying business decision
to proceed with or effect the Merger.

Pursuant to the terms and conditions of the Agreement and Plan of
Reorganization, dated September 16, 1996, by and between THBC and its wholly
owned subsidiary, Troy Hill Federal Savings Bank ("Troy Hill"), and PWBC,
(the "Agreement"), at the effective time of the Merger, PWBC will acquire all
of THBC's issued and outstanding shares of common stock (1,067,917 shares as
of the date of the Agreement) and the holders of such shares of common stock
shall have the right to receive either (i) $21.15 in cash per share of THBC
Common Stock or (ii) the number of shares of PWBC's Common Stock which equals
the result of dividing $21.15 by the "Average Share Price", as defined in
Section 1.03 of the Agreement, in exchange for each share of THBC Common
Stock.  Aggregate Cash Consideration to be received by THBC shareholders will
equal 40% of the aggregate total consideration which results by multiplying
$21.15 times the number of shares of THBC Common Stock at the effective time. 
Therefore, 60% of total consideration will be PWBC common stock, pursuant to
terms described in the Agreement. 

In addition, the holders of unexercised and outstanding options awarded
pursuant to the THBC 1994 Stock Option Plan, will elect to receive, for each
share subject to such option, either (i) cash equal to the difference between
$21.15 and the option exercise price, or (ii) an option to purchase shares of
PWBC common stock in an

amount and at an exercise price determined pursuant to Section 1.06 of the
Agreement.  The complete terms of the proposed transaction are described in
the Agreement, and this summary is qualified in its entirety by reference
thereto.

Charles Webb & Company, as part of its investment banking business, is
regularly engaged in the evaluation of businesses and securities in
connection with mergers and acquisitions, negotiated underwritings, and
distributions of listed and unlisted securities.  We are familiar with the
market for common stocks of publicly traded banks, thrifts and bank and
thrift holding companies.

In September, 1996, you engaged us to issue a fairness opinion to be
delivered upon execution of an agreement for the acquisition of THBC.  Prior
to your execution of the Agreement with PWBC, we reviewed certain financial
and other business data supplied to us by THBC including audited financial
statements for the years ended June 30, 1995 and 1994 and a draft of June 30,
1996 financial statements and certain other information we deemed relevant. 
We considered historical quotations and the prices of recorded transactions
in THBC's common stock since its public offering and conversion to a stock
holding company on June, 1994.  We reviewed financial and stock market data
of other thrifts, particularly in the Mid-Atlantic region, and the financial
and structural terms of several other recent transactions involving savings
and loan mergers and acquisitions or proposed changes of control of
comparably situated companies.

For PWBC, we reviewed the audited financial statements for the fiscal years
ended December 31, 1995  1994, 1993 and quarterly financial statements
(unaudited) for the quarters ending March 31, 1996, June 30, 1996 and related
SEC reports and certain other information deemed relevant.  We considered
historical quotations and the prices of recorded transactions in PWBC's
common stock.  For comparative purposes, we reviewed financial and stock
merger data of other financial institutions in the Mid-Atlantic region.

For purposes of this opinion we have relied, without independent
verification, on the accuracy and completeness of the material furnished to
us by THBC and PWBC and the material otherwise made available to us,
including information from published sources, and we have not made any
independent effort to verify such data.  With respect to the financial
information, including forecasts and asset valuations we received from THBC,
we assumed (with your consent) that they had been reasonably prepared
reflecting the best currently available estimates and judgment of THBC's
management.  In addition, we have not made or obtained any independent
appraisals or evaluations of the assets or liabilities, and potential and/or
contingent liabilities of THBC or PWBC.  We have further relied on the
assurances of management of THBC and PWBC that they are not aware of any
facts that would make such information

inaccurate or misleading.  We express no opinion on matters of a legal,
regulatory, tax or accounting nature or the ability of the Merger, as set
forth in the Agreement, to be consummated.

In rendering our opinion, we have assumed that in the course of obtaining the
necessary approvals for the Merger, no restrictions or conditions will be
imposed that would have a material adverse effect on the contemplated
benefits of the Merger to THBC or the ability to consummate the Merger.  Our
opinion is based on the market, economic and other relevant considerations as
they exist and can be evaluated on the date hereof.

We have been engaged to issue a fairness opinion for a fee, a majority of
which is contingent upon the affirmative shareholder approval of the Merger. 
In addition, THBC has agreed to indemnify us for certain liabilities arising
out of our engagement by THBC in connection with the Merger.  We have also
performed various investment banking services for THBC in the past and have
received customary fees for such services.

Based upon and subject to the foregoing, as outlined in the foregoing
paragraphs and based on such other matters as we considered relevant, it is
our opinion that as of the date hereof, the consideration to be received by
the shareholders of THBC in the Merger is fair, from a financial point of
view, to the shareholders of THBC.

This opinion may not, however, be summarized, excerpted from or otherwise
publicly referred to without our prior written consent, although this opinion
may be included in its entirety in the proxy statements of THBC used to
solicit shareholder approval of the Merger.  It is understood that this
letter is directed to the Board of Directors of THBC in its consideration of
the Agreement, and is not intended to be and does not constitute a
recommendation to any shareholder as to how such shareholder should vote with
respect to the Merger.

Very truly yours,

/s/ Charles Webb & Company

<PAGE>

         (b) EXCEPTIONS.--(1) Except as otherwise provided in paragraph 
    (2), the holders of the shares of any class or series of shares that, at
    the record date fixed to determine the shareholders entitled to notice
    of and to vote at the meeting at which a plan specified in any of
    section 1930, 1931(d), 1932(c) or 1952(d) is to be voted on, are either:

              (i)  listed on a national securities exchange; or

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

              (ii) Shares of any preferred or special class unless the

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

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

<PAGE>

    (d) NOTICE OF DISSENTERS RIGHTS.--Unless otherwise provided by statute,

         (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.

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).

Section 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

                                  3

<PAGE>

all relevant factors including the average rate currently paid by the 
corporation on its principal bank loans.

Section 1573. RECORD AND BENEFICIAL HOLDERS AND OWNERS.

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

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

Section 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.

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

the plan or other corporate action.  In either case, the notice shall:

                                  4

         (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.

Section 1576.  FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC.

    (a)  EFFECT OF FAILURE OF SHAREHOLDER TO ACT.--A shareholder who fails
to timely demand payment, or fails (in the case of certificated shares) to
timely deposit certificates, as required by a notice pursuant to section 1575
(relating to notice to demand payment) and 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.

Section 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 

                                  5

<PAGE>

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 corporation 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 dissenters had after making demand for payment of their
fair value.

Section 1578. ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES.

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

                                  6

<PAGE>

    (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.

Section 1579. VALUATION PROCEEDINGS 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.

Section 1580.  COSTS AND EXPENSES OF VALUATION PROCEEDINGS.

    (a)  GENERAL RULE.-- The costs and expenses of any proceeding under
section 1579 (relating to valuation proceedings generally), including the
reasonable compensation and expenses of the appraiser appointed by the court,
shall be determined by the court and assessed against the business
corporation except that any part of the costs and expenses may be apportioned
and assessed 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 to be dilatory, obdurate, arbitrary, vexatious or in
bad faith.

    (b)  ASSESSMENT OF COUNSEL FEES AND EXPERT FEES WHERE LACK OF GOOD FAITH
APPEARS.--Fees and expenses of counsel and of experts for the respective
parties may be assessed as the court deems appropriate against the
corporation and in favor of any or all dissenters if the corporation failed
to comply substantially with the requirements of this subchapter and may be
assessed against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses
are assessed acted in bad faith or in a dilatory, obdurate, arbitrary or
vexatious manner in respect to the rights provided by this subchapter.

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

Section 1930. DISSENTERS RIGHTS.

    (a) GENERAL RULE.--If any shareholder of a domestic business corporation
that is to be a party to a merger or consolidation pursuant to a plan of
merger or consolidation objects to the plan of merger or consolidation and
complies with the provisions of Subchapter D of Chapter 15 (relating to
dissenters rights), the shareholder shall be entitled to the rights and
remedies of dissenting shareholders therein provided, if any.  See also
section 1906(c) (relating to dissenters rights upon special treatment).

    (b) PLANS ADOPTED BY DIRECTORS ONLY.--Except as otherwise provided
pursuant to section 1571(c) (relating to grant of optional dissenters
rights), Subchapter D of Chapter 15 shall not apply to any of the shares of a
corporation that is a party to a merger or consolidation pursuant to section
1924(b)(1)(i) (relating to adoption by board of directors).

    (c) CROSS REFERENCES.--See sections 1571(b) (relating to exceptions) and
1904 (relating to de facto transaction doctrine abolished).

("THB"), and a related Agreement of Merger, pursuant to which, among other
things, THB will be merged into PennFirst (the "Merger").  If the Merger is
approved and consummated, each share of common stock of THB, par value $.01

of the Merger (other than shares as to which dissenters' rights have been
asserted and duly perfected in accordance with Pennsylvania law and shares

describes the matter to be voted upon, a voting instruction ballot for the

in the ESOP by marking, dating, signing and returning the enclosed voting
instruction ballot to Frank D. Martz, Senior Vice President of Operations and
Secretary of PennFirst.  Your voting instructions will remain completely

including the Merger.  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
