                         (A)  Each share of Penns Woods Common
     Stock issued and outstanding immediately prior to the
     Effective Date shall, on and after the Effective Date,

                         (B)  Each share of Penns Woods Common
     Stock issued and held in the treasury of Penns Woods as of 
     <PAGE 7> the Effective Date, if any, shall, on and after the

     treasury of Penns Woods.

                    (ii)  FNBSM Common Stock.

                         (A)   Subject to the provisions of
     Section 1.02(e)(iii) hereof with respect to dissenting
     shares, each share of FNBSM Common Stock issued and
     outstanding immediately prior to the Effective Date (other
     than shares then owned by Penns Woods, if any) shall, on the
     Effective Date, by reason of the Merger and without any
     action on the part of the holder thereof, be converted into
     and become 3.5 shares of Penns Woods Common Stock (subject
     to possible adjustment as set forth in Section 1.02(g), the
     "Exchange Ratio").

                         (B)  Each share of FNBSM Common Stock
     (other than trust account shares or DPC shares) owned by
     Penns Woods or a Penns Woods Subsidiary on the Effective
     Date, if any, shall be cancelled.

                         (C)  Each share of FNBSM Common Stock
     issued and held in the treasury of FNBSM or owned by FNBSM
     or any FNBSM Subsidiary (other than trust account shares or
     DPC shares) as of the Effective Date, if any, shall be
     cancelled, and no cash, stock or other property shall be
     delivered in exchange therefor.

                         (D)  No fraction of a whole share of
     Penns Woods Common Stock and no scrip or certificates
     therefor shall be issued in connection with the Merger.  Any
     former holder of FNBSM Common Stock who would otherwise be
     entitled to receive a fraction of a share of Penns Woods
     Common Stock shall receive, in lieu thereof, cash in an
     amount equal to such fraction of a share multiplied by the
     Penns Woods Market Price determined as of the Effective
     Date.

                    (iii)  Dissenting Shareholders of FNBSM.  If
     there are holders of FNBSM Common Stock who dissent from the
     Merger and exercise and perfect the right to obtain
     valuation of and payment for their shares ("Dissenting FNBSM
     Shares") pursuant to the NBA, the following provisions will
     govern payments to be made in respect of Dissenting FNBSM
     Shares:

                         (A)   all payments in respect of
     Dissenting FNBSM Shares, if any, will be made directly by
     Penns Woods or by JSSB, as the surviving corporation in the
     Merger; and

                         (B)  Dissenting FNBSM Shares, if any,
     will be deemed to have been retired and cancelled
     immediately prior to the Merger, with the effect that no 
     <PAGE 8> conversion thereof will occur pursuant to Section
     1.02(e)(ii) hereof.

               (f)  Surrender and Exchange of FNBSM Stock
Certificates.

                    (i)  Exchange of Certificates.  Each holder
     of shares of FNBSM Common Stock, other than holders of
     Dissenting FNBSM Shares, who surrenders to Penns Woods (or
     its agent) the certificate or certificates representing such
     shares will be entitled to receive, as soon as practicable
     after the Effective Date, in exchange therefor a certificate
     or certificates for the number of whole shares of Penns
     Woods Common Stock into which such holder's shares of FNBSM
     Common Stock have been converted pursuant to the Merger,
     together with a check for cash in lieu of any fractional
     share in accordance with Section 1.02(e)(ii)(D) hereof.

                    (ii)  Rights Evidenced by Certificates.  Each
     certificate for shares of Penns Woods Common Stock issued in
     exchange for certificates for FNBSM Common Stock pursuant to
     Section 1.02(f)(i) hereof will be dated the Effective Date
     and be entitled to dividends and all other rights and
     privileges pertaining to such shares of stock from and after
     the Effective Date.  Until surrendered, each certificate
     theretofore evidencing shares of FNBSM Common Stock will,
     from and after the Effective Date, evidence solely the right
     to receive certificates for shares of Penns Woods Common
     Stock pursuant to Section 1.02(f)(i) hereof and a check for
     cash in lieu of any fractional share in accordance with
     Section 1.02(e)(ii)(D) hereof.  If certificates for shares
     of FNBSM Common Stock are exchanged for Penns Woods Common
     Stock at a date following one or more record dates for the
     payment of dividends or of any other distribution on the
     shares of Penns Woods Common Stock, Penns Woods will pay
     cash in an amount equal to dividends theretofore payable on
     such Penns Woods Common Stock and pay or deliver any other
     distribution to which holders of shares of Penns Woods
     Common Stock have theretofore become entitled.  No interest
     will accrue or be payable in respect of dividends or cash
     otherwise payable under this Section 1.02(f) upon surrender
     of certificates for shares of Penns Woods Common Stock. 
     Notwithstanding the foregoing, no party hereto will be
     liable to any holder of Penns Woods Common Stock for any
     amount paid upon advice of legal counsel and in good faith
     to a public official or agency pursuant to any applicable
     abandoned property, escheat or similar law.  Until such time
     as certificates for shares of FNBSM Common Stock are
     surrendered by a FNBSM shareholder to Penns Woods for
     exchange, Penns Woods shall have the right to withhold
     dividends or any other distributions on the shares of Penns
     Woods Common Stock issuable to such shareholder.

                    (iii)  Exchange Procedures.  Each certificate
     for shares of FNBSM Common Stock delivered for exchange 
     <PAGE 9> under this Section 1.02(f) must be endorsed in
     blank by the registered holder thereof or be accompanied by
     a power of attorney to transfer such shares endorsed in
     blank by such holder.  If more than one certificate is
     surrendered at one time and in one transmittal package for
     the same shareholder account, the number of whole shares of
     Penns Woods Common Stock for which certificates will be
     issued pursuant to this Section 1.02(f) will be computed on
     the basis of the aggregate number of shares represented by
     the certificates so surrendered.  If shares of Penns Woods
     Common Stock or payments of cash are to be issued or made to
     a person other than the one in whose name the surrendered
     certificate is registered, the certificate so surrendered
     must be properly endorsed in blank, with signature(s)
     guaranteed, or otherwise in proper form for transfer, and
     the person to whom certificates for shares of Penns Woods
     Common Stock is to be issued or to whom cash is to be paid
     shall pay any transfer or other taxes required by reason of
     such issuance or payment to a person other than the
     registered holder of the certificate for shares of FNBSM
     Common Stock which are surrendered.  As promptly as
     practicable after the Effective Date, Penns Woods shall send
     or cause to be sent to each shareholder of record of FNBSM
     Common Stock transmittal materials for use in exchanging
     certificates representing FNBSM Common Stock for
     certificates representing Penns Woods Common Stock into
     which the former have been converted in the Merger. 
     Certificates representing shares of Penns Woods Common Stock
     and checks for cash in lieu of fractional shares shall be
     mailed to former shareholders of FNBSM as soon as reasonably
     possible but in no event later than twenty (20) business
     days following the receipt of certificates representing
     former shares of FNBSM Common Stock duly endorsed or
     accompanied by the materials referenced herein and delivered
     by certified mail, return receipt requested (but in no event
     earlier than the second business day following the Effective
     Date).

                    (iv)  Closing of Stock Transfer Books;
     Cancellation of FNBSM Certificates.  Upon the Effective
     Date, the stock transfer books for FNBSM Common Stock will
     be closed and no further transfers of shares of FNBSM Common
     Stock will thereafter be made or recognized.  All
     certificates for shares of FNBSM Common Stock surrendered
     pursuant to this Section 1.02(g) will be cancelled by Penns
     Woods.

               (g)  Anti-Dilution Provisions.  If Penns Woods
shall, at any time before the Effective Date, (A) issue a
dividend in shares of Penns Woods Common Stock, (B) combine the
outstanding shares of Penns Woods Common Stock into a smaller
number of shares, (C) subdivide the outstanding shares of Penns
Woods Common Stock, or (D) reclassify the shares of Penns Woods
Common Stock, or set a record date prior to the Effective Date
with respect to any of the foregoing, then, in any such event, 
<PAGE 10> the number of shares of Penns Woods Common Stock to be
delivered to FNBSM shareholders who are entitled to receive
shares of Penns Woods Common Stock in exchange for shares of
FNBSM Common Stock shall be adjusted so that each FNBSM
shareholder shall be entitled to receive in the Merger such
number of shares of Penns Woods Common Stock as such shareholder
would have been entitled to receive if the Effective Date had
occurred immediately prior to such event or the record date for
such event.  (By way of illustration, if Penns Woods shall
declare a stock dividend of 10% payable with respect to a record
date on or prior to the Effective Date, the Exchange Ratio
determined pursuant to Sections 1.02(e)(ii) hereof shall be
adjusted so that former shareholders of FNBSM would receive
3.85 shares of Penns Woods Common Stock in the Merger.)

acquired after the date hereof, good and, as to real property,
marketable title to all assets and properties owned by FNBSM in
the conduct of its business, whether such assets and properties
are real or personal, tangible or intangible, including assets
and property reflected in the balance sheets contained in the
FNBSM Regulatory Reports and in the FNBSM Financials or 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 the date of such balance sheets),
subject to no encumbrances, liens, mortgages, security interests
or pledges, except (i) those items that secure liabilities for
borrowed money and that are described in the FNBSM Disclosure
Schedule or permitted under Article IV hereof and (ii) statutory
liens for amounts not yet delinquent or which are being contested

properties as presently occupied and used by it.

               (b)  With respect to all agreements pursuant to
which FNBSM has purchased securities subject to an agreement to
resell, if any, FNBSM, has a valid, perfected first lien or

or exceeds the amount of the debt secured thereby.

               (c)  FNBSM currently maintains insurance in
amounts considered by FNBSM to be reasonable for its operations
and similar in scope and coverage to that maintained by other
businesses similarly engaged.  FNBSM has not received notice from
any insurance carrier that (i) such insurance will be cancelled
or that coverage thereunder will be reduced or eliminated or
(ii) premium costs with respect to such policies of insurance
will be substantially increased.  There are presently no material
claims pending under such policies of insurance and no notices
have been given by FNBSM under such policies.  All such insurance
is valid and enforceable and in full force and effect, and within
the last three years FNBSM has received each type of insurance
coverage for which it has applied and during such periods has not 
<PAGE 16> been denied indemnification for any material claims
submitted under any of its insurance policies.

          Section 2.10  Legal Proceedings.  FNBSM is not a party
to any, and there are no pending or, to the best of FNBSM's
knowledge, threatened legal, administrative, arbitration or other
proceedings, claims (whether asserted or unasserted), actions or
governmental investigations or inquiries of any nature
(i) against FNBSM, (ii) to which FNBSM's assets are or may be
subject, (iii) challenging the validity or propriety of any of
the transactions contemplated by this Agreement, or (iv) which
could adversely affect the ability of FNBSM to perform under this
Agreement or the Plan of Merger, except for any proceedings,
claims, actions, investigations or inquiries referred to in
clauses (i) or (ii) which, if adversely determined, individually
or in the aggregate, could not be reasonably expected to have a
Material Adverse Effect with respect to FNBSM.

          Section 2.11  Compliance With Applicable Law.

               (a)  FNBSM holds all licenses, franchises, permits
and authorizations necessary for the lawful conduct of its
businesses under, and have complied in all material respects
with, applicable laws, statutes, orders, rules or regulations of
any federal, state or local governmental authority relating to
them, other than where such failure to hold or such noncompliance
will neither result in a limitation in any material respect on
the conduct of its businesses or otherwise have a Material
Adverse Effect with respect to FNBSM.

               (b)  FNBSM has not received any notification or
communication from any Regulatory Authority (i) asserting that
FNBSM is not in compliance with any of the statutes, regulations
or ordinances which such Regulatory Authority enforces;
(ii) threatening to revoke any license, franchise, permit or
governmental authorization which is material to FNBSM;
(iii) requiring or threatening to require FNBSM, or indicating
that FNBSM may be required, to enter into a cease and desist
order, agreement or memorandum of understanding or any other
agreement restricting or limiting, or purporting to restrict or
limit, in any manner the operations of FNBSM, including without
limitation any restriction on the payment of dividends; or
(iv) directing, restricting or limiting, or purporting to direct,
restrict or limit, in any manner the operations of FNBSM,
including without limitation any restriction on the payment of
dividends (any such notice, communication, memorandum, agreement
or order described in this sentence is hereinafter referred to as
a "Regulatory Agreement").  FNBSM has not consented to or entered
into any Regulatory Agreement, except as heretofore disclosed to
Penns Woods.

          Section 2.12  ERISA.  FNBSM has previously delivered to
Penns Woods true and complete copies of all employee pension
benefit plans within the meaning of ERISA Section 3(2), profit
sharing plans, stock purchase plans, deferred compensation and 
<PAGE 17> supplemental income plans, supplemental executive
retirement plans, employment agreements, annual or long term
incentive plans, settlement plans, policies and agreements, group
insurance plans, and all other employee welfare benefit plans
within the meaning of ERISA Section 3(1) (including vacation pay,
sick leave, short-term disability, long-term disability, and
medical plans) and all other employee benefit plans, policies,
agreements and arrangements ("Employee Benefit Plans"), all of
which are set forth in the FNBSM Disclosure Schedule, maintained
or contributed to for the benefit of the employees or former
employees (including retired employees) and any beneficiaries
thereof or directors or former directors of FNBSM, together with
(i) the most recent actuarial (if any) and financial reports
relating to those plans which constitute "qualified plans" under
IRC Section 401(a), (ii) the most recent annual reports relating
to such plans filed by them, respectively, with any government
agency, and (iii) all rulings and determination letters which
pertain to any FNBSM Employee Benefit Plans.  To the best of
FNBSM's knowledge, neither FNBSM nor any pension plan maintained
by FNBSM, has incurred, directly or indirectly, within the past
six (6) years any liability under Title IV of ERISA (including to
the Pension Benefit Guaranty Corporation) or to the IRS with
respect to any pension plan qualified under IRC Section 401(a)
except liabilities to the Pension Benefit Guaranty Corporation
pursuant to ERISA Section 4007, all of which have been fully
paid, nor has any reportable event under ERISA Section 4043(b)
occurred with respect to any such pension plan.  With respect to
each FNBSM Employee Benefit Plan that is subject to Title IV of
ERISA, the present value of the accrued benefits under such plan,
based upon the actuarial assumptions used for funding purposes in
the plan's most recent actuarial report did not, as of its latest
valuation date, exceed the then current value of the assets of
such plan allocable to such accrued benefits.  With respect to
each FNBSM Employee Benefit Plan, FNBSM will have made on or
prior to the Closing Date, all payments required to be made by it
prior to the Closing Date and will have at least accrued as of
the Closing Date all payments due but not yet payable so that
there will not have been nor will there be any accumulated
funding deficiencies (as defined in ERISA or the Code) or waivers
of such deficiencies.  FNBSM has not incurred or is subject to
any liability under ERISA Section 4201 for a complete or partial
withdrawal from a multi-employer plan.  To the best of FNBSM's
knowledge, all "employee benefit plans," as defined in ERISA
Section 3(3), comply, and within the past six (6) years have
complied, in all material respects with (i) relevant provisions
of ERISA and (ii), in the case of plans intended to qualify for
favorable income tax treatment, provisions of the IRC relevant to
such treatment.  To the best of FNBSM's knowledge, no prohibited
transaction (which shall mean any transaction prohibited by ERISA
Section 406 and not exempt under ERISA Section 408 or any
transaction prohibited under IRC Section 4975) has occurred
within the past six (6) years with respect to any employee
benefit plan maintained by FNBSM that would result in the
imposition, directly or indirectly, of an excise tax under
IRC 4975 or other penalty under ERISA or the IRC, which, 
<PAGE 18> individually or in the aggregate, has resulted in or
will result in a Material Adverse Effect with respect to FNBSM. 
FNBSM provides continuation coverage under group health plans for
separating employees and "qualified beneficiaries" in accordance
with the provisions of IRC Section 4980B(f).  Such group health
plans are in compliance with Section 1862(b)(1) of the Social
Security Act.  There are no pending actions, claims or lawsuits
which have been asserted or instituted against any of FNBSM's
Employee Benefit Plans, the assets of any of the trusts under
such Plans, the plan sponsor, the plan administrator or against
any fiduciary of any of FNBSM's Employee Benefit Plans (other
than routine benefit claims) nor does FNBSM have knowledge of
facts which could form the basis of any such action, claim or
lawsuit.  There are no investigations or audits of any of FNBSM's
Employee Benefit Plans, any trusts under such plans, the plan
sponsor, the plan administrator or any fiduciary of any of
FNBSM's Employee Benefit Plans which have been threatened or
instituted nor does FNBSM have knowledge of facts which could
form the basis for any such investigation or audit.  No event has
occurred or will occur which will result in liability to FNBSM in
connection with any Employee Benefit Plan established,
maintained, or contributed to (currently or previously) by FNBSM
or by any other entity which, together with FNBSM, constitute
elements of either (i) a controlled group of corporations (within
the meaning of IRC Section 414(b)), (ii) a group of trades or
businesses under common control (within the meaning of IRC
Sections 414(c) or 4001), (iii) an affiliated service group
(within the meaning of IRC Section 414(m)), or (iv) another
arrangement covered by IRC Section 414(o).

          Section 2.13  Brokers, Finders and Financial Advisors. 
Neither FNBSM nor any of their respective officers, directors,
employees or agents, has employed any broker, finder or financial
advisor in connection with the transactions contemplated by this
Agreement or in connection with any other transaction or, except
for its commitments disclosed in the FNBSM Disclosure Schedule,
incurred any liability or commitment for any fees or commissions
to any such person in connection with the transactions
contemplated by this Agreement or in connection with any other
transaction, which has not been reflected in the FNBSM
Financials.

          Section 2.14  Environmental Matters.  To the knowledge
of FNBSM, neither FNBSM, nor any properties owned or operated by
FNBSM has been or is in violation of or liable under any
Environmental Law which violation or liability, individually or
in the aggregate, resulted in, or will result, in a Material
Adverse Effect with respect to FNBSM.  There are no actions,
suits or proceedings, or demands, claims, notices or
investigations (including without limitation notices, demand
letters or requests for information from any environmental
agency) instituted or pending, or to the knowledge of FNBSM,
threatened, relating to the liability of any property owned or
operated by FNBSM under any Environmental Law.
  <PAGE 19>
          Section 2.15  Loan Portfolio.  The allowance for loan
losses reflected, and to be reflected, in the FNBSM Regulatory
Reports, and shown, and to be shown, on the balance sheets
contained in the FNBSM Financials have been, and will be,
established in accordance with the requirements of generally
accepted accounting principles and all applicable regulatory
criteria.

          Section 2.16  Information to be Supplied.  The
information to be supplied by FNBSM for inclusion in the
Registration Statement (including the Prospectus/Proxy Statement)
will not, at the time the Registration Statement is declared
effective pursuant to the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact
necessary in order to make the statements therein not misleading. 
The information supplied, or to be supplied, by FNBSM for
inclusion in the Applications will, at the time such documents
are filed with any Regulatory Authority, be accurate in all
material aspects.

          Section 2.17  Related Party Transactions.  Except as
disclosed in the footnotes to the FNBSM Financials, FNBSM is not
a party to any transaction (including any loan or other credit
accommodation) with any Affiliate of FNBSM.  Any such transaction
(a) was made in the ordinary course of business, (b) was made on
substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable
transactions with other Persons, and (c) did not involve more
than the normal risk of collectability or present other
unfavorable features.  No loan or credit accommodation to any
Affiliate of FNBSM is presently in default or, during the three
year period prior to the date of this Agreement, has been in
default or has been restructured, modified or extended.  FNBSM
has not been notified that principal and interest with respect to
any such loan or other credit accommodation will not be paid when
due or that the loan grade classification accorded such loan or
credit accommodation by FNBSM is inappropriate.

          Section 2.18  Loans.  Each loan reflected as an asset
in the FNBSM Financial Statements (i) is evidenced by notes,
agreements or other evidences of indebtedness which are true,
genuine and correct (ii) to the extent secured, has been secured
by valid liens and security interests which have been perfected,
and (iii) is the legal, valid and binding obligation of the
obligor named therein, enforceable in accordance with its terms,
subject to bankruptcy, insolvency, fraudulent conveyance and
other laws of general applicability relating to or affecting
creditors' rights and to general equity principles, in each case
other than loans as to which the failure to satisfy the foregoing
standards would not have a Material Adverse Effect on FNBSM.

          Section 2.19  Quality of Representations.  The
representations made by FNBSM in this Agreement are true, correct
and complete in all material respects, and do not omit statements 
<PAGE 20> necessary to make them not misleading under all facts
and circumstances.

have, or will have as to property acquired after the date hereof,
good and, as to real property, marketable title to all assets and
properties owned by Penns Woods or any Penns Woods Subsidiary in
the conduct of its business, whether such assets and properties
are real or personal, tangible or intangible, including assets
and property reflected in the balance sheets contained in the 
<PAGE 25> Penns Woods Regulatory Reports and in the Penns Woods
Financials or acquired subsequent thereto (except to the extent
that such assets and properties have been disposed of for fair

security interests or pledges, except (i) those items that secure
liabilities for borrowed money and that are described in the
Penns Woods Disclosure Schedule or permitted under Article IV
hereof and (ii) statutory liens for amounts not yet delinquent or

businesses to occupy and use all such properties as presently
occupied and used by each of them.

               (b)  With respect to all agreements pursuant to
which Penns Woods or any Penns Woods Subsidiary has purchased

other collateral securing the repurchase agreement, and the value
of such collateral equals or exceeds the amount of the debt
secured thereby.

               (c)  Penns Woods and the Penns Woods Subsidiaries
currently maintain insurance in amounts considered by Penns Woods
to be reasonable for their respective operations and similar in
scope and coverage to that maintained by other businesses
similarly engaged.  Neither Penns Woods nor any Penns Woods
Subsidiary has received notice from any insurance carrier that
(i) such insurance will be cancelled or that coverage thereunder
will be reduced or eliminated or (ii) premium costs with respect
to such insurance will be substantially increased.  There are
presently no material claims pending under such policies of
insurance and no notices have been given by Penns Woods or JSSB
under such policies.  All such insurance is valid and enforceable
and in full force and effect, and within the last three years
Penns Woods has received each type of insurance coverage for
which it has applied and during such periods has not been denied
indemnification for any material claims submitted under any of
its insurance policies.

          Section 3.9  Legal Proceedings.  Neither Penns Woods

or any Penns Woods Subsidiary, (ii) to which Penns Woods' or any
Penns Woods Subsidiary's assets are or may be subject,

Agreement, except for any proceedings, claims, actions, 
<PAGE 26> investigations or inquiries referred to in clauses (i)
or (ii) which, individually or in the aggregate, could not be
reasonably expected to have a Material Adverse Effect with
respect to Penns Woods.

          Section 3.10  Compliance With Applicable Law.

necessary for the lawful conduct of their businesses under, and
have complied in all material respects with, applicable laws,
statutes, orders, rules or regulations of any federal, state or
local governmental authority relating to them, other than where
such failure to hold or such noncompliance will neither result in
a limitation in any material respect on the conduct of their
businesses nor otherwise have a Material Adverse Effect with
respect to Penns Woods.

               (b)  Neither Penns Woods nor any Penns Woods
Subsidiary has received any notification or communication from
any Regulatory Authority (i) asserting that Penns Woods or any
Penns Woods Subsidiary is not in compliance with any of the
statutes, regulations or ordinances which such Regulatory
Authority enforces; (ii) threatening to revoke any license,

Material Adverse Effect with respect to Penns Woods.  There are
no actions, suits or proceedings, or demands, claims, notices or
investigations (including without limitation notices, demand

information to be supplied by Penns Woods and JSSB for inclusion
in the Registration Statement (including the Prospectus/Proxy

Penns Woods for inclusion in the Applications will, at the time
such documents are filed with any Regulatory Authority, be
accurate in all material aspects.

          Section 3.16  Loans.  Each loan reflected as an asset
in the Penns Woods Financial Statements (i) is evidenced by
notes, agreements or other evidences of indebtedness which are

foregoing standards would not have a Material Adverse Effect with
respect to Penns Woods.

          Section 3.17  Quality of Representations.  The
representations made by Penns Woods in this Agreement are true,
correct and complete in all material respects and do not omit
statements necessary to make the representations not misleading

                    (v)  sell or otherwise dispose of any asset
     of FNBSM other than in the ordinary course of business
     consistent with past practice; subject any asset of FNBSM to
     a lien, pledge, security interest or other encumbrance
     (other than in connection with deposits, repurchase
     agreements, bankers acceptances, "treasury tax and loan"

     practice; incur any indebtedness for borrowed money (or
     guarantee any indebtedness for borrowed money), except in
     the ordinary course of business consistent with past
     practice;

                    (vi)  take any action which would result in

  <PAGE 30>
                    (viii)  waive, release, grant or transfer any

     with past practice;

                    (ix)  implement any pension, retirement,
     profit sharing, bonus, welfare benefit or similar plan or
     arrangement that was not in effect on the date of this
     Agreement, or materially amend any existing plan or
     arrangement except to the extent such amendments do not
     result in an increase in cost; provided, however, that FNBSM
     may contribute to the FNBSM defined contribution pension
     plan an amount as provided in Section 4.10(a)(i) of this
     Agreement;

                    (xiii)  enter into any interest rate swap or
     similar commitment, agreement or arrangement;

     of payment to any individual under any employment agreement;

                    (xv)  intentionally and knowingly take any
     action that would preclude satisfaction of the condition to

previously contracted in the normal course of business, issuance
of loans, or transactions in the investment securities portfolio
by FNBSM or repurchase agreements made, in each case, in the
ordinary course of business; or (iii) undertake or enter any
lease, contract or other commitment for its account, other than
in the normal course of providing credit to customers as part of
its banking business, involving a payment by FNBSM of more than
$25,000 annually, or containing a material financial commitment
and extending beyond 12 months from the date hereof.

          Section 4.02  Access; Confidentiality.

               (a)  From the date of this Agreement through the
Closing Date, FNBSM or Penns Woods, as the case may be, shall
afford to, and Penns Woods shall cause each Subsidiary to afford
to, the other party and its authorized agents and
representatives, complete access to their respective properties,
assets, books and records and personnel, at reasonable hours and
after reasonable notice for the purpose of undertaking a
comprehensive due diligence investigation; and the officers of
FNBSM and Penns Woods will furnish any person making such
investigation on behalf of the other party with such financial
and operating data and other information with respect to the
businesses, properties, assets, books and records and personnel
as the person making such investigation shall from time to time
reasonably request.

               (b)  FNBSM and Penns Woods each agree to conduct
such investigation and discussions hereunder in a manner so as
not to interfere unreasonably with normal operations and customer
and employee relationships of the other party.

               (c)  In addition to the access permitted by
subparagraph (a) above, from the date of this Agreement through
the Closing Date, FNBSM shall permit employees of JSSB reasonable
access to and participation in matters relating to problem loans,
loan restructurings and loan work-outs, provided that nothing
contained in this subparagraph shall be construed to grant JSSB
or any of its employees any final decision-making authority with
respect to such matters.

               (d)  If the transactions contemplated by this
Agreement shall not be consummated, FNBSM and Penns Woods will
each destroy or return all documents and records obtained from
the other party or its representatives, during the course of its
investigation and will cause all information with respect to the
other party obtained pursuant to this Agreement or preliminarily
thereto to be kept confidential, except to the extent such
information becomes public through no fault of the party to whom
the information was provided or any of its representatives or
agents and except to the extent disclosure of any such  <PAGE 32>
information is legally required.  FNBSM and Penns Woods shall
each give prompt notice to the other party of any contemplated
disclosure where such disclosure is so legally required.

          Section 4.03  Regulatory Matters and Consents.

               (a)  Penns Woods and FNBSM will prepare all
Applications and make all filings for, and use their best efforts
to obtain as promptly as practicable after the date hereof, all
necessary permits, consents, approvals, waivers and
authorizations of all Regulatory Authorities necessary or
advisable to consummate the transactions contemplated by this
Agreement.

               (b)  FNBSM will furnish Penns Woods with all

Regulatory Authority and provide FNBSM a reasonable opportunity
to suggest changes to such Applications, which suggested changes
Penns Woods may, in its reasonable discretion accept or reject,
(ii) copies of all Applications filed by Penns Woods and
(iii) copies of all documents filed by Penns Woods under the
Exchange Act.

               (e)  FNBSM will cooperate with Penns Woods in the
foregoing matters and will furnish Penns Woods with all
information concerning FNBSM as may be necessary or advisable in
connection with any Application or filing (including the
Registration Statement and any report filed with the SEC) made by
or on behalf of Penns Woods to any Regulatory Authority in
connection with the transactions contemplated by this Agreement,
and such information will be accurate and complete in all
material respects.  In connection therewith, FNBSM will provide
certificates and other documents reasonably requested by Penns
Woods.

          Section 4.04  Taking of Necessary Action.

               (a)  Penns Woods and FNBSM shall each use its best
efforts in good faith, and each of them shall cause any
Subsidiaries to use their 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 Section 4.03
of this Agreement, and (ii) take or cause to be taken all action
necessary or desirable on its part using its best efforts so as 
<PAGE 33> to permit completion of the Merger including, without
limitation, (A) obtaining the consent or approval of each
individual, partnership, corporation, association or other
business or professional entity whose consent or approval is
required or desirable for consummation of the transactions
contemplated hereby (including assignment of leases without any
change in terms), provided that shall not agree to make any
payments or modifications to agreements in connection therewith
without the prior written consent of Penns Woods, and
(B) requesting the delivery of appropriate opinions, consents and
letters from its counsel and independent auditors.  No party
hereto shall take, or cause, or to the best of its ability permit
to be taken, any action that would substantially impair the
prospects of completing the Merger; provided that nothing herein
contained shall preclude Penns Woods or FNBSM from exercising its
rights under this Agreement.

               (b)  Penns Woods and FNBSM shall promptly prepare
a Prospectus/Proxy Statement to be mailed to shareholders of
FNBSM in connection with the meeting of FNBSM shareholders and
transactions contemplated hereby, and to be filed by Penns Woods
with the SEC in the Registration Statement, which
Prospectus/Proxy statement shall conform in all material respects
to all applicable legal requirements.  Penns Woods shall, as
promptly as practicable following the preparation thereof, file
the Registration Statement with the SEC and FNBSM and Penns Woods
shall use all reasonable efforts to have the Registration
Statement declared effective under the Securities Act as promptly
as practicable after such filing.  Penns Woods will advise FNBSM,
promptly after Penns Woods receives notice thereof, of the time
when the Registration Statement has become effective or any
supplement or amendment has been filed, of the issuance of any
stop order or the suspension of the qualification of the shares
of capital stock issuable pursuant to the Registration Statement,
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.  Penns Woods shall use its best efforts to obtain,
prior to the effective date of the Registration Statement, all
necessary state securities laws or "Blue Sky" permits and
approvals required to carry out the transactions contemplated by
this Agreement.  Penns Woods shall provide FNBSM with as many
copies of such Registration Statement and all amendments thereto
promptly upon the filing thereof as FNBSM may reasonably request.

          Section 4.05  Certain Agreements.

               (a)  In the event of any threatened or actual
claim, action, suit, proceeding or investigation, whether civil,
criminal or administrative, whether or not brought by or in the
name of FNBSM, in which any person who is now, or has been at any
time prior to the date of this Agreement, or who becomes prior to
the Effective Date, a director or officer or employee of FNBSM
(the "Indemnified Parties") is, or is threatened to be, made a
party to a suit based in whole or in part on, or arising in whole 
<PAGE 34> or in part out of, or pertaining to (i) the fact that
he is or was a director, officer or employee of FNBSM or any of
its respective predecessors or (ii) this Agreement or any of the
transactions contemplated hereby, whether in any case asserted or
arising before or after the Effective Date, the parties hereto
agree to cooperate and use their best efforts to defend against
and respond thereto to the maximum extent permitted by the BCL,
the NBA and the Articles of Association and Bylaws of FNBSM.  On
or after the Effective Date, Penns Woods shall indemnify, defend
and hold harmless all prior and then-existing directors and
officers of FNBSM, against (i) all losses, claims, damages,
costs, expenses, liabilities or judgments or amounts that are
paid in settlement (with the approval of Penns Woods which
approval shall not be unreasonably withheld) of or in connection
with any claim, action, suit, proceeding or investigation,
whether or not brought by or in the name of FNBSM, based in whole
or in part on or arising in whole or in part out of the fact that
such person is or was a director, officer or employee of FNBSM or
any FNBSM Subsidiary, whether pertaining to any matter existing
or occurring at or prior to or after the Effective Date and
whether asserted or claimed prior to, or at or after, the
Effective Date ("Indemnified Liabilities") and (ii) all
Indemnified Liabilities based in whole or in part on, or arising
in whole or in part out of, or pertaining to this Agreement or
the transactions contemplated hereby, to the same extent as such
officer, director or employee may be indemnified by FNBSM as of
the date hereof including the right to advancement of expenses,
provided, however, that any such officer, director or employee of
FNBSM may not be indemnified by Penns Woods and/or JSSB if such
indemnification is prohibited by applicable law.

               (b)  Penns Woods shall maintain FNBSM's existing
directors' and officers' liability insurance policy (or a policy
providing comparable coverage amounts on terms generally no less
favorable, including Penns Woods' existing policy if it meets the
foregoing standard) covering persons who are currently covered by
such insurance for a period of five years after the Effective
Date.

               (c)  On or prior to the Effective Date, Penns
Woods and JSSB shall enter into employment agreements with
William H. Rockey and Rickey H. Brooks, to be effective as of the
Effective Date, on terms mutually satisfactory to Penns Woods and
such individuals.  Such agreements shall, among other things,
(i) provide for a term of three years from the Effective Date and
automatic annual renewals thereafter absent notice of nonrenewal
by either party, (ii) provide for a minimum base salary equal to
the base salary of the executive immediately prior to the
Effective Date, (iii) provide for a severance payment equivalent
to the greater of 24 months' base salary or base salary payable
over the remaining term of the agreement in the event the
executive's employment is terminated involuntarily or the
executive terminates employment for "good reason" following a
"change in control" of Penns Woods, and (iv) provide that the
executive shall be eligible for consideration to receive stock 
<PAGE 35> option grants under Penns Woods' stock option plans
then in effect in the same manner as other executive officers of
Penns Woods.

          Section 4.06  No Other Bids and Related Matters.  So
long as this Agreement remains in effect, FNBSM shall not and
shall not authorize or permit any of its directors, officers,
employees or agents, to directly or indirectly (i) respond to,
solicit, initiate or encourage any inquiries relating to, or the
making of any proposal which relates to, an Acquisition
Transaction (as defined below), (ii) recommend or endorse an
Acquisition Transaction, (iii) participate in any discussions or
negotiations regarding an Acquisition Transaction, (iv) provide
any third party (other than Penns Woods or an affiliate of Penns
Woods) with any nonpublic information in connection with any
inquiry or proposal relating to an Acquisition Transaction, or
(v) enter into an agreement with any other party with resect to
an Acquisition Transaction.  Notwithstanding the foregoing, the
Board of Directors of FNBSM may respond to unsolicited inquiries
relating to an Acquisition Transaction or the Board of Directors
of FNBSM may recommend or endorse an Acquisition Transaction, in
each case, if it receives an unqualified written opinion of
outside counsel that the failure to do so would constitute a
breach of their fiduciary duty.  In the event of any such
response by FNBSM, Penn Woods shall have the right, but not the
obligation, to terminate this Agreement at any time thereafter
without penalty or further liability.  As used in this Agreement,
"Acquisition Transaction" shall mean any of the following
transactions:  (i) a merger or consolidation, or any similar
transaction, involving FNBSM, (ii) a purchase, lease or other
acquisition of all or a substantial portion of the assets or
liabilities of FNBSM hereto, or (iii) a purchase or other
acquisition (including by way of share exchange, tender offer,
exchange offer or otherwise) of 20% or more of the outstanding
shares of FNBSM Common Stock.  FNBSM shall notify Penns Woods
immediately if (i) any such discussions or negotiations are
sought to be initiated with it by any other person, or (ii) if
any such requests for information, inquiries, proposals or
communications are received from any other person, except
analysts, Regulatory Authorities and holders of FNBSM Common
Stock in the ordinary course of business.

          Section 4.07  Duty to Advise; Duty to Update FNBSM's
Disclosure Schedule.  FNBSM shall promptly advise Penns Woods of
any change or event having a Material Adverse Effect on it or
which it believes would or would be reasonably likely to cause or
constitute a material breach of any of its representations,
warranties or covenants set forth herein.  FNBSM shall update
FNBSM's Disclosure Schedule as promptly as practicable after the
occurrence of an event or fact which, if such event or fact had
occurred prior to the date of this Agreement, would have been
disclosed in the FNBSM Disclosure Schedule.  The delivery of such
updated Disclosure Schedule shall not relieve FNBSM from any
breach or violation of this Agreement and shall not have any 
<PAGE 36> effect for the purposes of determining the satisfaction
of the condition set forth in Sections 5.02(c) hereof.

          Section 4.08  Board and Committee Minutes.  FNBSM shall
provide Penns Woods, within 30 days after any meeting of the
Board of Directors of FNBSM, or any committee thereof, or any
senior management committee, a copy of the minutes of such
meeting, except that with respect to any meeting held within 30
days of the Closing Date, such minutes shall be provided prior to
the Closing Date.

          Section 4.09  Additional Undertakings by FNBSM and
Penns Woods.

               (a)  From and after the date of this Agreement,
FNBSM shall:

                    (i)  Shareholders Meeting.  Submit this
     Agreement to its shareholders for approval at a meeting to
     be held as soon as practicable, and use its best efforts to
     cause its Boards of Director to unanimously recommend
     approval of this Agreement to FNBSM shareholders; and

                    (ii)  Committee Meetings.  Permit a
     representative of Penns Woods, who is reasonably acceptable
     to FNBSM, to attend all meetings of FNBSM's Board of
     Directors, and all committee meetings of FNBSM's management,
     including, without limitation, any loan or asset/liability
     committee.

               (b)  From and after the date of this Agreement,
Penns Woods shall:

                    (i)  Approval of Bank Plan of Merger. 
     Approve the Plan of Merger as sole shareholder of JSSB and
     obtain the approval of, and cause the execution and delivery
     of, the Plan of Merger; and

                    (ii)  Delivery of Securities Documents.

          Section 4.10  Employee Benefits and Termination
Benefits.

               (a)  FNBSM Pension and Other Plans.  

                    (i)  As of the Closing Date, Penns Woods
     shall become plan sponsor to the FNBSM Pension Plan and
     shall continue to maintain the FNBSM Pension Plan after the
     Closing Date and up through the end of the FNBSM Pension
     Plan's October 14, 1999 Plan year for the benefit of
     employees of FNBSM who become employees of Penns woods or
     any Penns Woods subsidiary.  Upon the earlier of the last
     business day immediately preceding the Closing Date or
     December 31, 1998 (the "Pre-Fund Contribution Date"), FNBSM 
     <PAGE 38> shall make a contribution to the FNBSM Pension
     Plan in an amount equal to the "Contribution Amount."  For
     purposes of this Section 4.10(a)(1), the Contribution Amount
     shall be determined by multiplying (A) times (B) as follows:

                         (A)  The required contribution formula
          amount in effect under the FNBSM Pension Plan as of the
          execution of this Agreement, multiplied by

                         (B)  The compensation of FNBSM Pension
          Plan "Eligible Participants" from October 15, 1998
          through the Pre-Fund Contribution Date hereof, plus the
          projected compensation of FNBSM Pension Plan Eligible
          Participants from the Pre-Fund Contribution Date up
          through October 14, 1999.

     For purposes of this Section 4.10(a)(i), Eligible
     Participants shall mean those FNBSM employees who are
     eligible to participate in the FNBSM Pension Plan as of
     October 15, 1998 and those FNBSM employees who will be
     eligible to participate in the FNBSM Pension Plan by
     October 14, 1999.  For purposes of this Section 4.10(a)(i)
     and calculating the Contribution Amount an Eligible
     Participant shall receive a full year of service credit for
     compensation determination purposes for the FNBSM Pension
     Plan's October 15, 1998 through October 14, 1999 plan year. 
     Penn Woods agrees that from the Closing Date and up through
     the close of the FNBSM Pension Plan's year ending
     October 14, 1999, Penn Woods will not amend the FNBSM
     Pension Plan, except as required by law or to clarify
     participation of FNBSM employees who become employees of
     Penns Woods or of any Penns Woods Subsidiary and will not
     freeze or reduce the FNBSM Pension Plan contribution
     formula.  As of the close of the FNBSM Pension Plan year
     ending October 14, 1999, Penn Woods, at its election, may
     freeze, merge, consolidate or terminate the FNBSM Pension
     Plan.

                    (ii)  Except as set forth in
     Section 4.10(a)(i) as to the FNBSM Pension Plan, on and
     after the Effective Date, the employee pension and welfare
     benefit plans of Penns Woods and FNBSM may, at Penns Woods'
     election and subject to the requirements of the IRC,
     continue to be maintained separately or consolidated,
     provided that FNBSM employees shall, except as provided
     below, be entitled to participate in the employee pension
     and welfare plans of Penns Woods as follows:  FNBSM
     employees will be eligible to participate in the defined
     contribution pension plan of Penns Woods (with a cash or
     deferred feature) on the first quarterly entry date for new
     participants under the terms of such plan concurrent with or
     immediately following the Effective Date and FNBSM employees
     will be eligible to participate in the defined benefit
     pension plan of Penns Woods effective October 1, 1999. 
     FNBSM employees shall receive credit for service with FNBSM 
     <PAGE 39> under any Penns Woods benefit plan, or new Penns
     Woods benefit plan, for purposes of eligibility and vesting
     determination but not for purposes of benefit accrual.

               (b)  Split Dollar Agreements.  Penns Woods agrees
to continue to pay, or cause the continuation and payment of, the
premiums relating to the current split-dollar life insurance
arrangements for William H. Rockey and Rickey B. Brooks, as
described in Section 2.12 of the FNBSM Disclosure Schedule, until
the respective retirements of William H. Rockey and Rickey B.
Brooks provided that FNBSM and each of such individuals executes
a customary form of written agreement applicable to such
arrangements which is reasonably satisfactory to Penns Woods and
which provides, among other things, for the reimbursement of all
premiums paid on behalf of such individual upon death,
retirement, or other termination of employment.

               (c)  Severance Policy.  Penns Woods agrees to
cause JSSB to provide any employee of FNBSM whose employment is
involuntarily terminated other than for Cause (as defined below)
within one year after the Effective Date or who within such one-
year period is offered but declines to accept employment at a
location more than 35 miles from such employee's work location
with FNBSM provided such employees execute such documentation as
Penns Woods may reasonably require:  (i) one week of base salary
for each year of service with FNBSM with a minimum of two weeks
and a maximum of twenty weeks; (ii) continued medical insurance
coverage during the time period set forth in the preceding
clause (i) to the extent permitted under Penns Woods' health
insurance programs or, to the extent impermissible, reimbursement
for the cost of continuation coverage provided under IRC Section
4980B(f) during the time period set forth in the preceding
clause (i), and (iii) a cash payment for any vacation days
accrued but unused in the year in which employment terminates. 
For purposes of this Section 4.10(c), "Cause" shall mean
termination because of the employee's personal dishonesty,
willful misconduct, breach of fiduciary duty involving personal
profit, intentional failure to perform stated duties or willful
violation of any law, rule or regulation (other than traffic
violations or similar offenses).  The benefits provided to
terminated FNBSM employees under this subsection are the only
severance benefits payable by FNBSM under any plan or policy. 
The benefits payable to FNBSM employees under this subsection or
otherwise shall in any event be in lieu of any termination
benefits to which such employees would otherwise be entitled
under Penns Woods' or JSSB's severance policies or programs then
in effect.  The benefits payable under this subsection shall not
apply to any FNBSM employee who enters into a written employment
agreement with Penns Woods or JSSB.

               (d)  Other Benefits.  Notwithstanding anything
contained in this Agreement to the contrary, FNBSM shall be
permitted to pay customary year-end bonuses to employees for the
year ending December 31, 1998 in an amount not to exceed $1,200
per employee and shall be permitted to make cash payments to its 
<PAGE 40> eligible employees in lieu of accumulated sick leave
pursuant to the program set forth in Section 4.01 of the FNBSM
Disclosure Schedule.

          Section 4.11  Duty to Advise; Duty to Update Penns
Woods' Disclosure Schedule.  Penns Woods shall promptly advise
FNBSM of any change or event having a Material Adverse Effect on
it or on any Penns Woods Subsidiary or which it believes would or
would be reasonably likely to cause or constitute a material
breach of any of its representations, warranties or covenants set
forth herein.  Penns Woods shall update Penns Woods' Disclosure
Schedule as promptly as practicable after the occurrence of an
event or fact which, if such event or fact had occurred prior to
the date of this Agreement, would have been disclosed in the
Penns Woods Disclosure Schedule.  The delivery of such updated
Disclosure Schedule shall not relieve Penns Woods from any breach
or violation of this Agreement and shall not have any effect for
the purposes of determining the satisfaction of the condition set
forth in Sections 5.01(c) hereof.

     Effect with respect to Penns Woods, on the one hand, or, in
     the case of termination by Penns Woods, there shall have

     Date; or

            FORM OF OPINION OF COUNSEL TO PENNS WOODS

          FNBSM shall have received from counsel to Penns Woods,
an opinion, dated as of the Closing Date, substantially to the
effect that, subject to customary exceptions and qualifications:

          (a)  Penns Woods and JSSB have full corporate power to
carry out the transactions contemplated in the Agreement and the
Plan of Merger, respectively.  The execution and delivery of the
Agreement and the Plan of Merger and the consummation of the
transactions contemplated thereunder have been duly and validly
authorized by all necessary corporate action on the part of Penns
Woods and JSSB, and the Agreement and the Plan constitute valid
and legally binding obligations of Penns Woods and JSSB,
respectively, except as may be limited by bankruptcy, insolvency,
reorganization, moratorium, receivership, conservatorship, and
other laws affecting creditors' rights generally and institutions
the deposits of which are insured by the FDIC, and as may be
limited by the exercise of judicial discretion in applying
principles of equity.  Subject to satisfaction of the conditions
set forth in the Agreement, neither the transactions contemplated
in the Agreement or the Plan, nor compliance by Penns Woods and
JSSB with any of the respective provisions thereof, will
(i) conflict with or result in a breach or default under (A) the
articles of incorporation or bylaws of Penns Woods or JSSB, or,
(B) based solely on certificates of officers and without
independent verification, to the knowledge of such counsel, any
note, bond, mortgage, indenture, license, agreement or other
material instrument or obligation to which Penns Woods or JSSB is
a party; or (ii) based solely on certificates of officers and
without independent verification, to the knowledge of such
counsel, result in the creation or imposition of any material
lien or encumbrance upon the property of Penns Woods or JSSB,
except such material lien, instrument or obligation that has been
disclosed pursuant to the Agreement or the Plan; or (iii) violate
in any material respect any order, writ, injunction or decree
known to such counsel, or any federal or Pennsylvania statute,
rule or regulation applicable to Penns Woods or JSSB.

          (b)  JSSB is a validly existing state-chartered bank
organized and in good standing under the laws of the Commonwealth
of Pennsylvania.  The deposits of JSSB are insured to the maximum
extent provided by law by the Federal Deposit Insurance
Corporation.

          (c)  There is, to the knowledge of such counsel, no
legal, administrative, arbitration or governmental proceeding or 
<PAGE 1> investigation pending or threatened to which Penns Woods
or JSSB is a party which would, if determined adversely to Penns
Woods or JSSB, have a material adverse effect on the financial
condition or results of operation of Penns Woods and JSSB taken
as a whole, or which presents a claim to restrain or prohibit the
transactions contemplated by the Agreement and the Plan,
respectively.

          (d)  To the knowledge of such counsel, no consent,
approval, authorization or order of any federal or state court or
federal or state governmental agency or body is required for the
consummation by Penns Woods or JSSB of the transactions
contemplated by the Agreement and the Plan, except for such
consents, approvals, authorizations or orders as have been
obtained.

          (e)  Upon the filing and effectiveness of the Articles
of Merger with the PDB and the PDS with respect to the Merger,
the mergers of JSSB and FNBSM contemplated by the Agreement and
the Plan, respectively, will have been effected in compliance
with all applicable federal and Pennsylvania laws and regulations
in all material respects.

          (f)  The shares of Penns Woods Common Stock to be
issued in connection with the merger of FNBSM and JSSB
contemplated by the Agreement have been duly authorized and will,
when issued in accordance with the terms of the Agreement, be
validly issued, fully paid and nonassessable, free and clear of
any mortgage, pledge, lien, encumbrance or claim (legal or
equitable).

          FORM OF TAX OPINION OF COUNSEL TO PENNS WOODS

     Penns Woods and FNBSM shall have received an opinion of
Stevens & Lee substantially to the effect that, under the
provisions of the IRC:

     1.   The Merger will constitute a reorganization within the
meaning of Sections 368(a)(1)(A) and 368(a)(2)(D) of the IRC.

     2.   Penns Woods, FNBSM and JSSB will each be "a party to a
reorganization" within the meaning of Section 368(b) of the IRC.

     3.   Neither FNBSM nor JSSB will recognize any gain or loss
by reason of the Merger upon the transfer of FNBSM's assets to
JSSB and the assumption by JSSB of the liabilities of FNBSM.

     4.   The basis of the FNBSM assets in the hands of JSSB will
be the same as the basis of such assets in the hands of FNBSM
immediately prior to the Merger.

     5.   The holding period of the FNBSM assets in the hands of
JSSB will include the period during which such assets were held
by FNBSM prior to the Merger.

     6.   No gain or loss will be recognized by the shareholders
of FNBSM on the receipt of Penns Woods Common Stock (including
fractional share interests) solely in exchange for their shares
of FNBSM Common Stock.

     7.   The basis of the Penns Woods Common Stock (including
fractional share interests) to be received by the FNBSM
shareholders in the Merger will be the same as the basis of the
FNBSM Common Stock surrendered in exchange therefor.

     8.   The holding period of the Penns Woods Common Stock
(including fractional share interests) to be received by the
FNBSM shareholders in the Merger will include the period during
which the FNBSM shareholders held their FNBSM Common Stock,
provided the shares of FNBSM Common Stock are held as a capital
asset on the Effective Date.

     9.   The payment of cash in lieu of fractional share
interests of Penns Woods Common Stock will be treated as if the
fractional share interests were distributed as part of the Merger

                  FORM OF OPINION OF COUNSEL TO
               FIRST NATIONAL BANK OF SPRING MILLS

          Penns Woods shall have received from counsel to FNBSM
an opinion, dated as of the Closing Date, substantially to the
effect that, subject to customary exceptions and qualifications:

          (a)  FNBSM has full corporate power to carry out the
transactions contemplated in the Agreement and the Plan of
Merger, respectively.  The execution and delivery of the
Agreement and the Plan of Merger and the consummation of the
transactions contemplated thereunder have been duly and validly
authorized by all necessary corporate action on the part of
FNBSM, and the Agreement and the Plan constitute valid and
legally binding obligations, in accordance with their respective
terms, of FNBSM, except as may be limited by bankruptcy,
insolvency, reorganization, moratorium, receivership,
conservatorship, and other laws affecting creditors' rights
generally and institutions the deposits of which are insured by
the FDIC, and as may be limited by the exercise of judicial
discretion in applying principles of equity.  Subject to
satisfaction of the conditions set forth in the Agreement,
neither the transactions contemplated in the Agreement and the
Plan, nor compliance by FNBSM with any of the respective
provisions thereof, will (i) conflict with or result in a breach
or default under (A) the articles of association or bylaws of
FNBSM, or (B) based solely on certificates of officers and
without independent verification, to the knowledge of such
counsel, any note, bond, mortgage, indenture, license, agreement
or other instrument or obligation to which FNBSM is a party; or
(ii) based solely on certificates of officers, to the knowledge
of such counsel, result in the creation or imposition of any
material lien, instrument or encumbrance upon the property of
FNBSM, except such material lien, instrument or obligation that
has been disclosed to Penns Woods pursuant to the Agreement and
the Plan, or (iii) violate in any material respect any order,
writ, injunction, or decree known to such counsel, or any
statute, rule or regulation applicable to FNBSM.

          (b)  FNBSM is a validly existing national bank
organized and in good standing under the laws of the United
States of America.  The deposits of FNBSM are insured to the
maximum extent provided by law by the Federal Deposit Insurance
Corporation.

          (c)  There is, to the knowledge of such counsel, no
legal, administrative, arbitration or governmental proceeding or 
<PAGE 1> investigation pending or threatened to which FNBSM is a
party which would, if determined adversely to FNBSM, have a
material adverse effect on the business, properties, results of
operations, or condition, financial or otherwise, of FNBSM taken
as a whole or which presents a claim to restrain or prohibit the
transactions contemplated by the Agreement and the Plan,
respectively.

          (d)  To the knowledge of such counsel, no consent,
approval, authorization, or order of any federal or state court
or federal or state governmental agency or body, or of any third
party, is required for the consummation by FNBSM of the
transactions contemplated by the Agreement and the Plan, except
for such consents, approvals, authorizations or orders as have
been obtained.  <PAGE 2>
