      Item 5 - Other Events

   On November 25, 1996, S & T Bancorp, Inc. (S&T)
signed a definitive agreement in which Peoples Bank of Unity will be merged 
into S&T's subsidiary, S&T Bank.   Peoples Bank is a state chartered commercial 
bank that is headquartered in Plum Borough, an eastern suburb of Pittsburgh.  
Peoples Bank had assets of $288 million, equity of approximately $49 million 
as of September 30,1996 and has six full service community offices.

   Under the terms of the agreement, Peoples Bank shareholders will receive
a fixed exchange ratio of 26.25 S&T common shares for each of the 115,660
outstanding Peoples Bank shares.  This will result in an expected tax-free
exchange and the merger will be accounted for as a pooling-of-interests.
Based upon the recent market price of S&T Bancorp common stock, the 
transaction has a value of approximately $94 million.  Subject to regulatory
approvals and approval of the shareholders of both companies, the transaction
is expected to close by April 30, 1997.

2.10.   Allowance for Loan Losses

       The allowance for loan losses reflected on the
Peoples Financial Statements, as of their respective
dates, is adequate in all material respects under the
requirements of generally accepted accounting principles

outstanding loans.

2.11.   Tax Matters

     (a)    Peoples has timely filed all federal income
tax returns required to be filed by it for each year
through December 31, 1995 and has timely filed, or
caused to be filed, all other federal, state, local and
foreign Tax Returns required to be filed with respect to
Peoples.  

     (b)    All Taxes due in respect of any tax periods

is not delinquent in the payment of any Tax, assessment
or governmental charge, and Peoples has not requested

Returns in respect of any taxable year or portion
thereof which have not since been filed.  No
deficiencies for any Tax, assessment or governmental
charge have been proposed, asserted or assessed

agreements in effect with respect to Peoples to extend
the period of limitations for the assessment or
collection of any Tax.

     (d)    Termination of the employment of any
employees of Peoples following consummation of the
transactions contemplated hereby will not cause Peoples
to make or to be required to make any "excess parachute
payment" as that term is defined in Section 280G of the
Code.


2.12.   Employee Benefit Plans

     (a)    Peoples has Previously Disclosed true and
complete copies of all qualified pension or
profit-sharing plans, any deferred compensation,
consulting, bonus or group insurance contract or any
other incentive, welfare or employee benefit plan or
agreement maintained for the benefit of employees or
former employees of Peoples, and will make available to
S&T (i) the most recent actuarial and financial reports
prepared with respect to any plans qualified under
Section 401(a) of the Code, (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 plan
qualified under Section 401(a) of the Code.

     (b)    Neither Peoples (nor any pension plan
maintained by it) has incurred or reasonably expects to
incur any material liability to the Internal Revenue
Service with respect to any plan qualified under
Section 401(a) of the Code.  Except as Previously
Disclosed, Peoples has never sponsored, participated in
or maintained any defined benefit pension plan.  Peoples
has never participated in a multiemployer plan as such
term is defined in ERISA.

     (c)    A favorable determination letter has been
issued by the Internal Revenue Service with respect to
each "employee pension plan" (as defined in Section 3(2)
of ERISA) of Peoples which is intended to be a qualified
plan to the effect that such plan is qualified under
Section 401 of the Code and tax exempt under Section 501
of the Code.  No such letter has been revoked or
threatened to be revoked and Peoples does not know of
any ground on which such revocation may be based.  Such
plans have been operated in all material respects in
accordance with their terms and applicable law.

     (d)    No prohibited transaction (which shall mean
any transaction prohibited by Section 406 of ERISA and
not exempt under Section 408 of ERISA) has occurred with
respect to any "employee benefit plan" (as defined in
Section 3(3) of ERISA) maintained by Peoples which would
result in the imposition, directly or indirectly, of an
excise tax under Section 4975 of the Code or the
correction of which would have a material adverse effect
on the financial condition, results of operations or
business of Peoples.


2.13.   Certain Contracts

     (a)    Except as Previously Disclosed, Peoples is
neither a party to, nor is it bound by, (i) any material
agreement, arrangement or commitment whether or not made
in the ordinary course of business (other than loans or
loan commitments made in the ordinary course of the
banking business of Peoples), (ii) any agreement,
indenture or other instrument relating to the borrowing
of money by Peoples or the guarantee by Peoples of any
such obligation, other than instruments relating to

both, would constitute such a default.

incurred nor paid any obligation or liability that would
be material to Peoples, except obligations incurred or
paid in connection with transactions in the ordinary
course of business of Peoples consistent with its past
practices or except as Previously Disclosed or reflected
in the Peoples Financial Statements.  

     (d)    Except as Previously Disclosed, Peoples is
not a party to any transaction (other than agreements

hereof) with (i) any person who has been an executive
officer or a director of Peoples since January 1, 1993,
(ii) any spouse of any such officer or director,
(iii) any parent, child, brother, sister, or other
family relation of any such officer or director who has
the same home as such officer or director, (iv) any
corporation or other entity of which any such officer or
director or any such family relation is an officer,
director, partner, or greater than 5% shareholder (based
on percentage ownership of voting stock) or (v) any
"affiliate" or "associate" of any such persons or
entities (as such terms are defined in the rules and 

regulations promulgated under the Securities Act),
including, without limitation, (x) any transaction
involving a contract, agreement, or other arrangement
providing for the employment of, furnishing of
materials, products or services by, rental of real or
personal property from, or otherwise requiring payments
to, any such person or entity, and (y) loans (including
any loan guaranty) outstanding at the date hereof, but
not (z) deposit accounts maintained at Peoples in the
ordinary course of its banking business.

       Except as Previously Disclosed, there are no
actions, suits or proceedings instituted, pending or, to
the knowledge of Peoples, threatened against Peoples or
against any asset, interest or right of Peoples that
would, if determined adversely to Peoples, have a
material adverse effect on Peoples.  To the knowledge of
Peoples, there are no actual or threatened actions,
suits or proceedings which present a claim to restrain

subsidiaries or affiliates any material cost or
obligation in connection therewith.  Except as
Previously Disclosed, there are no actions, suits or
proceedings instituted, pending or, to the knowledge of
Peoples, threatened against any present or former
director or executive officer of Peoples that might give
rise to a claim for indemnification that would, if

effect on Peoples, and, to the knowledge of Peoples,
there is no reasonable basis for any such action, suit
or proceeding.

2.15.   Compliance with Laws

       Except as Previously Disclosed, Peoples is in
compliance in all material respects with all statutes
and regulations applicable to the conduct of its

state or local government (i) asserting a material
violation of any such statute or regulation,
(ii) threatening to revoke any license, franchise,
permit or government authorization or (iii) restricting
or in any way limiting its operations.  Peoples is not
subject to any regulatory or supervisory cease and
desist order, agreement, directive, memorandum of
understanding or commitment, and it has not received any 

communication requesting that it enter into any of the
foregoing.  Without limiting the generality of the
foregoing, Peoples has timely filed all currency
transaction reports required to be filed and taken all
other actions required under the Currency and Foreign

maintained by Peoples.  Except as Previously Disclosed,
Peoples has not received any notice of a premium
increase or cancellation with respect to any of its
insurance policies or bonds and, within the last three
years, Peoples has not been refused any insurance
coverage sought or applied for, and Peoples has no
reason to believe that existing insurance coverage
cannot be renewed as and when the same shall expire,
upon terms and conditions as favorable as those
presently in effect, other than possible increases in
premiums or unavailability in coverage that have not
resulted from any extraordinary loss experience of
Peoples.  

2.18.   Deposit Insurance

       Except as Previously Disclosed, Peoples is an
insured bank as defined in the FDIA, and Peoples has
paid all assessments and filed all reports required by
the FDIA.

2.19.   Environmental Liability

       There is no legal, administrative, arbitral or
other proceeding, or, to the knowledge of Peoples,
claim, action, cause of action, or governmental
investigation of any nature seeking to impose, or that
could result in the imposition, on Peoples of any
liability arising under any local, state or federal 

environmental statute, regulation or ordinance
including, without limitation, the Comprehensive
Environmental Response, Compensation and Liability Act
of 1980, as amended, pending or, to the knowledge of
Peoples, threatened against Peoples, which liability
might have a material adverse effect on the financial
condition, results of operations or business of Peoples;
except as Previously Disclosed, to the knowledge of
Peoples, there is no reasonable basis for any such
proceeding, claim, action or governmental investigation
that would impose any such liability; and Peoples is not
subject to any agreement, order, judgment, decree or
memorandum by or with any court, governmental authority,
regulatory agency or third party imposing any such
liability.

2.20.   Certain Information

       The information contained in the Proxy Statement,
other than information subject to Section 3.9(a) hereof,
at the time the Proxy Statement is mailed to
shareholders of Peoples up to and including the time of
the Peoples shareholders' meeting to vote upon the
Merger, (i) shall comply in all material respects with
the applicable provisions of the regulations of the
Securities Laws and (ii) shall not contain any untrue
statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make
the statements contained therein not misleading.

2.21.   Pooling of Interests

       As of the date of this Reorganization Agreement,
Peoples, after having consulted with its independent
auditors concerning the requirements of the relevant
accounting literature and SEC pronouncements and
interpretations, does not believe that it has taken any
steps which would preclude S&T from accounting for the
Merger under the pooling of interests method and knows
of no reason relating to it which would reasonably cause
it to believe that the Merger will not qualify as a
pooling of interests for financial accounting
purposes.


                      ARTICLE 3 
         REPRESENTATIONS AND WARRANTIES OF S&T

       S&T hereby represents and warrants to Peoples as

     (d)    This Reorganization Agreement constitutes a
legal, valid and binding obligation of S&T and S&T Bank
and the Plan of Merger, upon the authorization,
execution and delivery thereof by the parties thereto,
will constitute a legal, valid and binding obligation of
S&T and S&T Bank, enforceable against them in accordance
with their respective terms, subject to receipt of
shareholder approval and, as to enforceability, subject
to bankruptcy, insolvency, fraudulent conveyance and
other laws of general applicability relating to or
affecting creditors' rights and to general equity

     (e)    Neither the execution and delivery of this
Reorganization Agreement or the Plan of Merger, nor

the provisions hereof or thereof shall (i) conflict with
or result in a breach of any provision of the articles
of incorporation, charter or by-laws of S&T or S&T Bank,
(ii) constitute or result in a breach of any term,
condition or provision of, or constitute a default
under, or give rise to any right of termination,
cancellation or acceleration with respect to, or result
in the creation of any lien, charge or encumbrance upon 

any property or asset of S&T or S&T Bank pursuant to,
any note, bond, mortgage, indenture, license, agreement
or other instrument or obligation or (iii) violate any
order, writ, injunction, decree, statute, rule or
regulation applicable to S&T or S&T Bank, except for
such violations, rights, conflicts, breaches, creations
or defaults which, either individually or in the
aggregate would not have a material adverse effect on
S&T.

3.4.   SEC Documents; Regulatory Filings

       S&T has filed all SEC Documents required by the
Securities Laws and such SEC Documents complied, as of
their respective dates, in all material respects with
the Securities Laws.  S&T and each S&T subsidiary has
filed all reports required by statute or regulation to

agency and such reports were prepared, in all material
respects, in accordance with the applicable statutes,
regulations and instructions in existence as of the date
of filing of such reports.

3.5.   Financial Statements; Books and Records;
       Minute Books

       The S&T Financial Statements fairly present the
consolidated financial position of S&T as of the dates
indicated and the results of operations, changes in
shareholders' equity and cash flows of S&T for the
periods then ended in conformity with generally accepted
accounting principles applied on a consistent basis
except as disclosed therein.  The books and records of
S&T fairly reflect in all material respects the
transactions to which it is a party or by which its
properties are subject or bound.  Such books and records
have been properly kept and maintained and are in
compliance in all material respects with all applicable
legal and accounting requirements.  The minute books of
S&T contain accurate records of all corporate actions of
its shareholders and Board of Directors (including
committees of its Board of Directors).

       S&T has not suffered any material adverse change
in its financial condition, results of operations or
business since December 31, 1995.


3.7.   Absence of Undisclosed Liabilities

       S&T has no liability (contingent or otherwise)
that is material to S&T, or that, when combined with all
similar liabilities, would be material to S&T, except as
disclosed in the S&T Financial Statements.

3.8.   Allowance for Loan Losses

       The allowance for loan losses reflected on the
S&T Financial Statements, as of their respective dates,
is adequate in all material respects under the
requirements of generally accepted accounting principles
to provide for reasonably anticipated losses on
outstanding loans.

3.9.   Certain Information

     (a)    The information provided by S&T to Peoples
for use in the Proxy Statement, at the time the Proxy
Statement is mailed to shareholders of Peoples and at
all subsequent times up to and including the time of the
Peoples shareholders' meeting to vote upon the Merger,
shall not contain any untrue statement of a material
fact or omit to state a material fact required to be
stated therein or necessary to make the statements
contained therein, in light of the circumstances under
which they were made, not misleading.

     (b)    When the Registration Statement or any
post-effective amendment thereto shall become effective,
and at all times subsequent to such effectiveness up to
and including the time of the S&T shareholders' meeting
to vote upon the Merger, such Registration Statement and
all amendments or supplements thereto, with respect to
all information set forth therein furnished by S&T
relating to S&T, (i) shall comply in all material
respects with the applicable provisions of the
Securities Laws, and (ii) shall not contain any untrue
statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make
the statements contained therein not misleading.

3.10.   Brokers and Finders

       Neither S&T nor any of its officers, directors or
employees, has employed any broker, finder or financial
advisor or incurred any liability for any fees or
commissions in connection with the transactions
contemplated herein or the Plan of Merger, except that 

S&T has engaged and will pay a fee or commission to
McDonald & Company Securities, Inc.

3.11.   Compliance with Laws

       Each of S&T and its subsidiaries is in compliance
in all material respects with all statutes and
regulations applicable to the conduct of its business,
and none of S&T, its subsidiaries or, to the knowledge
of S&T, any director or executive officer of S&T or any
of its subsidiaries has received notification from any
agency or department of federal, state or local
government (i) asserting a material violation of any
such statute or regulation, (ii) threatening to revoke
any license, franchise, permit or government
authorization or (iii) restricting or in any way
limiting its operations.  None of S&T or any subsidiary
of S&T is subject to any regulatory or supervisory cease
and desist order, agreement, directive, memorandum of
understanding or commitment, and none of them has
received any communication requesting that they enter
into any of the foregoing.

3.12.   Legal Proceedings

       To the knowledge of S&T, there are no actions,
suits or proceedings instituted, pending or, to the
knowledge of S&T, threatened against S&T or against any
asset, interest or right of S&T that would, if
determined adversely to S&T, have a material adverse
effect on S&T.  To the knowledge of S&T, there are no
actual or threatened actions, suits or proceedings which
present a claim to restrain or prohibit the transactions
contemplated herein or to impose upon S&T, Peoples or
any of their respective subsidiaries or affiliates any
material cost or obligation in connection therewith. 
There are no actions, suits or proceedings instituted,
pending or, to the knowledge of S&T, threatened against
any present or former director or executive officer of
S&T that might give rise to a claim for indemnification
that would, if determined adversely to S&T, have a
material adverse effect on S&T, and, to the knowledge of
S&T, there is no reasonable basis for any such action,
suit or proceeding.

3.13.   Pooling of Interests 

       As of the date of this Reorganization Agreement,
S&T, after having consulted with its independent
auditors concerning the requirements of the relevant
accounting literature and SEC pronouncements and 

interpretations, does not believe that it has taken any
steps which would preclude it from accounting for the
Merger under the pooling of interests method and knows
of no reason relating to it which would reasonably cause
it to believe that the Merger will not qualify as a
pooling of interests for financial accounting
purposes.

                      ARTICLE 4

Agreement and the Plan of Merger and, in the case of
S&T, the issuance of S&T Common Stock thereunder, to
their respective shareholders for approval at special
meetings to be held as soon as practicable.  Subject to
the fiduciary duties of the respective boards of
directors of S&T and Peoples as determined by each after
consultation with such board's counsel, the boards of
directors of S&T and Peoples shall recommend at the
respective shareholders' meetings that the shareholders
vote in favor of such approval.

4.2.   Proxy Statement; Registration Statement

       The Board of Directors of Peoples will direct
that this Reorganization Agreement and the Plan of
Merger be submitted to Peoples' shareholders for
approval at a special meeting to be held as soon as

hereof, S&T and Peoples shall cooperate in the
preparation of the Proxy Statement to be mailed to the
shareholders of S&T and Peoples in connection with the
Merger and the transactions contemplated thereby and to
be filed by S&T as part of the Registration Statement. 
S&T will advise Peoples, promptly after it receives
notice thereof, of the time when the Registration
Statement or any post-effective amendment thereto has
become effective or any supplement or amendment has been
filed, of the issuance of any stop order, of the
suspension of qualification of the S&T Common Stock
issuable in connection with the Merger for offering or
sale in any jurisdiction, or the initiation or threat of
any proceeding for any such purpose, or of any request
by the SEC for the amendment or supplement of the
Registration Statement or for additional information. 
S&T shall take all actions necessary to register or
qualify the shares of S&T Common Stock to be issued in
the Merger pursuant to all applicable state "blue sky"
or securities laws and shall maintain such registrations 

or qualifications in effect for all purposes hereof. 
S&T shall apply for approval to have the shares of S&T
Common Stock authorized for trading on the Nasdaq

approval of the transactions contemplated herein and in
the Plan of Merger (i) to the FDIC pursuant to 12 U.S.C.
1828 (c)(2) and (ii) to the Department of Banking
pursuant to Section 1603 of the Pennsylvania Banking
Code, and each of the parties hereto shall submit any

furnished by it shall be true, correct and complete in
all material respects.

4.5.   Best Efforts; Certain Notices and Information

     (a)    S&T and Peoples shall each use its best
efforts in good faith to (i) furnish such information as
may be required in connection with the preparation of
the documents referred to in Sections 4.2 and 4.4 above
and (ii) take or cause to be taken all action necessary
or desirable on its part so as to permit consummation of
the Merger at the earliest possible date, including,
without limitation, (1) obtaining the consent or
approval of each individual, partnership, corporation,
association or other business or professional entity
whose consent or approval is required for consummation
of the transactions contemplated hereby, provided that
Peoples shall not agree to make any payments or
modifications to agreements in connection therewith
without the prior written consent of S&T, except where
such payment or modification would not have a material
adverse effect on Peoples, and (2) requesting the
delivery of appropriate opinions, consents and letters 

from its counsel and independent auditors.  No party
hereto shall take or fail to take, or to the best of its
ability permit to be taken or omitted to be taken by any
third persons, any action that would substantially
impair the prospects of completing the Merger pursuant
to this Reorganization Agreement and the Plan of Merger,
that would materially delay such completion, or that
would adversely affect the qualification of the Merger
for pooling of interests accounting treatment or as a
reorganization within the meaning of Section 368(a) of
the Code.

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

     (c)    Each party shall provide and shall request
its auditors to provide the other party with such
historical financial information regarding it (and
related audit reports and consents) as the other party
may reasonably request for securities disclosure
purposes.

4.6.   Investigation and Confidentiality

       Peoples and S&T will each keep the other advised
of all material developments relevant to its business
and to the consummation of the transactions contemplated
herein.  Peoples and S&T may make or cause to be made
such investigation of the financial and legal
condition of the other as such party reasonably deems
necessary or advisable in connection with the
transactions contemplated herein and in the Plan of
Merger, provided, however, that such investigation shall
be reasonably related to such transactions and shall not
interfere unnecessarily with normal operations.  Peoples
and S&T agree to furnish the other and the other's
advisors with such financial data and other information
with respect to its business and properties as such
other party shall from time to time reasonably request. 
No investigation pursuant to this Section 4.6 shall
affect or be deemed to modify any representation or
warranty made by, or the 

conditions to the obligations to consummate the Merger
of, any party hereto.  Each party shall, and shall cause
its directors, officers, attorneys and advisors to,
maintain the confidentiality of all information obtained
in such investigation which is not otherwise publicly
disclosed by the other party, said undertaking with
respect to confidentiality to survive any termination of
this Agreement pursuant to Section 6.1 hereof.  In the
event of termination of this Reorganization Agreement,
each party shall return to the furnishing party or
destroy and certify the destruction of all information
previously furnished in connection with the transactions
contemplated by this Reorganization Agreement.  

4.7.   Press Releases

       Peoples and S&T shall agree with each other as to
the form and substance of any press release related to
this Reorganization Agreement and the Plan of Merger or
the transactions contemplated hereby or thereby, and
shall consult each other as to the form and substance of
other public disclosures related thereto, provided,
however, that nothing contained herein shall prohibit
either party, following notification to the other party,
from making any disclosure which its counsel deems
necessary.

otherwise provided for by this Reorganization Agreement,

Reorganization Agreement and the Plan of Merger shall be
consummated at a closing to be held at such location as
the parties may agree, on the first business day
following satisfaction of the conditions to consummation

       Indemnification

       (a)  All employees of Peoples as of the Effective
Date shall become employees of S&T or a subsidiary of

employment with S&T after the Effective Date.  As soon
as practicable after the Effective Date, S&T shall
provide or cause to be provided to all employees of
Peoples who remain employed by S&T benefits which in the
aggregate are no less favorable than those generally
afforded to other S&T employees holding similar
positions, provided that for purposes of determining
eligibility for and vesting of such employee benefits,
service with Peoples prior to the Effective Date shall
be treated as service to the same extent as if such
persons had been employees of S&T or affiliates of S&T,
and provided further that this Section 4.10(a) shall not
be construed (i) to limit the ability of S&T and its
affiliates to terminate the employment of any employee
or to review employee benefits programs from time to
time and to make such changes as they deem appropriate
or (ii) to require S&T or its affiliates to provide
employees or former employees with post-retirement

period of three years, S&T shall indemnify persons who
serve as directors and officers of Peoples as of the
date of this Reorganization Agreement for claims arising
prior to the Effective Date as provided under S&T's
By-Laws as delivered to Peoples prior to the execution

been entitled to indemnification under such S&T By-Laws
prior to the Effective Date.

treatment.

       (b)  S&T shall use its best efforts to publish no
later than 90 days after the end of the first month
after the Effective Date in which there are at least 30
days of post-Merger combined operations (which month
may be the month in which the Effective Date occurs),

                      ARTICLE 6 
           TERMINATION, WAIVER AND AMENDMENT

6.1.   Termination

             This Reorganization Agreement and the Plan of
Merger may be terminated, either before or after
approval by the shareholders of Peoples:

          (a)   At any time on or prior to the Effective
Date, by the mutual consent in writing of the parties
hereto;

          (b)   At any time on or prior to the Closing Date,
by S&T in writing, if Peoples has, or by Peoples in
writing, if S&T has, in any material respect, breached
(i) any covenant or agreement contained herein or in the
Plan of Merger or (ii) any representation or warranty
contained herein if the failure of any such
representation and warranty to be true and correct has,
or is reasonably likely to have, a material adverse
effect upon S&T or Peoples, and in either 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 Closing
Date;

          (c)   On the Closing Date, by either party hereto
in writing, if any of the conditions precedent set forth
in Article 5 hereof with respect to such party have not
been satisfied or fulfilled;

          (d)   At any time, by either party hereto in
writing, if the applications for prior approval referred
to in Section 4.4 hereof have been denied, and the time
period for appeals and requests for reconsideration has
run;

          (e)   At any time, by either party hereto in
writing, if the shareholders of S&T or Peoples do not
approve the transactions contemplated herein at the
annual or special meetings duly called for that purpose; 

          (f)   At any time, by either party in writing, if
such party determines in good faith that any condition
precedent to such party's obligations to consummate the
Merger is or would be impossible to satisfy, provided
that the terminating party has given the other party
written notice with respect thereto at least 10 days
prior to such termination and has given the other party 

a reasonable opportunity to discuss the matter with a
view to achieving a mutually acceptable resolution; or

          (g)   By either party hereto in writing, if the
Closing Date has not occurred by the close of business

6.2.   Effect of Termination

       In the event this Reorganization Agreement or the
Plan of Merger is terminated pursuant to Section 6.1
hereof, this Reorganization Agreement and the Plan of
Merger shall become void and have no effect, except that
(i) the provisions relating to confidentiality and
expenses set forth in Sections 4.6 and 7.1 hereof,
respectively, shall survive any such termination and
(ii) a termination pursuant to Section 6.1(b)(i) shall
not relieve the breaching party from liability for an
uncured willful breach of a covenant or agreement giving
rise to such termination.

6.3.   Survival of Representations, Warranties
       and Covenants

       All representations, warranties and covenants in
this Reorganization Agreement and the Plan of Merger or
in any instrument delivered pursuant hereto or thereto
shall expire on, and be terminated and extinguished at,
the Effective Date other than covenants that by their
terms are to survive or be performed after the Effective
Date, provided that no such representations, warranties
or covenants shall be deemed to be terminated or
extinguished so as to deprive S&T or Peoples (or any
director, officer or controlling person thereof) of any
defense in law or equity which otherwise would be
available against the claims of any person, including,
without limitation, any shareholder or former
shareholder of either S&T or Peoples, the aforesaid
representations, warranties and covenants being material
inducements to the consummation by S&T, S&T Bank and
Peoples of the transactions contemplated herein.

6.4.   Waiver

       Except with respect to any required shareholder
or regulatory approval, S&T and Peoples, respectively,
by written instrument signed by an executive officer of
such party, may at any time (whether before or after
approval of this Reorganization Agreement and the Plan
of Merger by the shareholders of S&T and Peoples) extend
the time for the performance of any of the obligations 

or other acts of Peoples, on the one hand, or S&T or S&T
Bank, on the other hand, and may waive (i) any
inaccuracies of such parties in the representations or
warranties contained in this Reorganization Agreement,
the Plan of Merger or any document delivered pursuant
hereto or thereto, (ii) compliance with any of the
covenants, undertakings or agreements of such parties,
or satisfaction of any of the conditions precedent to
its obligations, contained herein or in the Plan of
Merger or (iii) the performance by such parties of any
of its obligations set out herein or therein; provided,
however, that no such waiver executed after approval of
this Reorganization Agreement and the Plan of Merger by
the shareholders of S&T or Peoples shall change the
number of shares of S&T Common Stock into which each
share of Peoples Common Stock shall be converted
pursuant to the Merger.

6.5.   Amendment or Supplement

       This Reorganization Agreement and the Plan of
Merger may be amended or supplemented at any time by
mutual agreement of the parties hereto, in the case of
this Reorganization Agreement, or thereto, in the case
of the Plan of Merger.  Any such amendment or supplement
must be in writing and approved by their respective
boards of directors and/or officers authorized thereby
and shall be subject to the proviso in Section 6.4
hereof.  

                      ARTICLE 7 
                     MISCELLANEOUS

7.1.   Expenses

          (a)    Each party hereto shall bear and pay all
costs and expenses incurred by it in connection with the
transactions contemplated in this Reorganization
Agreement, including fees and expenses of its own
financial consultants, accountants and counsel, except
that S&T shall bear and pay all costs and expenses
incurred in connection with printing the Registration
Statement and joint Proxy Statement and prospectus of
S&T and Peoples.

          (b)    Peoples and S&T each acknowledge that the
other has spent, and will be required to spend,
substantial time and effort in examining the business,
properties, affairs, financial condition and prospects
of the other, has incurred, and will continue to incur,
substantial fees and expenses in connection with such 

examination, the preparation of this Reorganization
Agreement and the accomplishment of the transactions
contemplated hereby, and will be unable to evaluate and,
possibly, make investments in or acquire other entities
due to the limited number of personnel available for
such purpose and the constraints of time.  Therefore, to
induce S&T to enter into this Reorganization Agreement,
(i) if S&T terminates this Reorganization Agreement
pursuant to Section 6.1(b) or (c) by reason of Peoples'
failure to meet any condition contained in
Section 5.3(a) or (b) due to Peoples' knowing and
intentional misrepresentation or knowing and intentional
breach of warranty or breach of any covenant or
agreement, and within 9 months from the date of
termination a Competing Transaction is consummated or
Peoples shall have entered into an agreement or an
agreement in principle which if consummated would
constitute a Competing Transaction or (ii) if Peoples
terminates this Reorganization Agreement pursuant to
Section 6.1(b) or (c) because this Reorganization
Agreement did not receive the requisite vote of Peoples
stockholders and within 9 months from the date of
termination (other than a termination pursuant to
Article IX of the Plan of Merger) a Competing
Transaction is consummated or Peoples shall have entered
into an agreement which if consummated would constitute
a Competing Transaction, then Peoples shall pay to S&T a
fee in the amount of $1,600,000, not as a penalty but as
full and complete liquidated damages.  Upon payment of
such fee, Peoples shall have no further liability to S&T
at law or equity.  The fee shall be payable to S&T
notwithstanding that any action taken by the Board of
Directors of Peoples which may give rise to the
obligation to pay the fee may have been taken in
accordance with the fiduciary duties of the Board of
Directors.  Any payment required pursuant to this
Section 7.1(b) shall be made as promptly as practicable,
but in no event later than two business days after the
date it becomes payable hereunder and shall be made by
wire transfer of immediately available funds to an
account designated by S&T.  In the event that S&T is
entitled to the fee, Peoples shall also pay S&T interest
at the rate of 6% per year on any amounts that are not
paid when due, plus all costs and expenses in connection
with or arising out of the enforcement of the obligation
of Peoples to pay the fee or such interest.

7.2.   Entire Agreement

       This Reorganization Agreement and the Plan of
Merger contain the entire agreement between the parties 

with respect to the transactions contemplated hereunder
and thereunder and supersede all prior arrangements or
understandings with respect thereto, written or oral,
other than documents referred to herein or therein.  The
terms and conditions of this Reorganization Agreement
and the Plan of Merger shall inure to the benefit of and
be binding upon the parties hereto and thereto and their
respective successors.  Nothing in this Reorganization
Agreement or the Plan of Merger, expressed or implied,
is intended to confer upon any party, other than the
parties hereto and thereto, and their respective
successors, any rights, remedies, obligations or
liabilities.

obligations under this Reorganization Agreement to any
