         6. Eligibility to Participate in Plan.  The individuals who are
            ----------------------------------
eligible to participate in the Plan are the Company's Outside Directors. A

shall be transferred or designated to this account.

          10.  Establishment of Deferred Compensation Units.  On the first day 
               --------------------------------------------
following the credit of the Participant's Deferred Compensation Account, the 
account shall be converted and credited with the number of Units ("Units") 
calculated by dividing the deferred Compensation credited as of the most recent 
date by the Fair Market Value of the Company's Common Stock.

          11.  Credits to Account of Participants.
               ---------------------------------- 

               (a)  So long as this Plan remains in effect, the Company shall
                    credit to each Participant's Deferred Compensation Account
                    throughout the term of his service as a Director with the
                    Company, amounts, calculated in Units, equal to dividends
                    payable in cash or property paid from time to time on issued
                    and outstanding shares of Common Stock equal to the number
                    of Units in his account, so that the amount of each such
                    credit will be equivalent to dividends which the Participant
                    would have received had he been the owner of the number of
                    shares of Common Stock equal to the number of Units in his
                    account. No such credit shall be made with respect to any
                    dividend paid after a Participant's service as a Director of
                    the Company terminates or after any date of termination of
                    this Plan, even though the record date is prior thereto.

               (b)  On the last day of each calendar year, or on the date of
                    termination of his services as a Director, if earlier, each
                    Participant's Deferred Compensation Account, shall be
                    revalued at an amount equal to the number of Units then
                    standing to his credit times the Fair Market Value per
                    share.

               (c)  Upon the termination of service of any Participant as a
                    Director of the Company, there shall be paid to him the
                    aggregate amount then standing to his credit in his Deferred
                    Compensation Account. Such amounts shall be payable in
                    accordance with the elections made under Paragraph 12.

 
          (d)  In the event of any stock dividend on the Common Stock or any
               split-up or combination of shares of the Common Stock,
               appropriate adjustment shall be made by the Administrative
               Committee in the aggregate number of Units standing to the credit
               of each Participant in his Deferred Compensation Account
               provided, however, that the Administrative Committee may, but
               shall not be required to, establish any fractional Units.

     12.  Distribution of Deferred Compensation Account.  The Deferred 
          ---------------------------------------------
Compensation Account of each Participant will be as follows:

          (a)  Payment. Upon termination of an Outside Director's service with
               ------- 
               the Board, the balance of the Participant's Deferred Compensation
               Account shall be paid to him according to the method and at the
               times selected by the Participant in his "Distribution Form" a
               copy of which is attached hereto as Exhibit B, which must be
                                                   ---------  
               properly executed and delivered to the Administrative Committee.
               If the Participant's Distribution Form does not pre-date his
               termination, the prior Distribution Form will supersede the
               current form. If no Distribution Form has been in effect for at
               least one year, a lump sum distribution will occur as early as
               administratively possible after termination of service.

          (b)  Methods of Payment. The Participant may elect one of the
               ------------------  
               following methods of payment of his Deferred Compensation Account
               on his Distribution Form:

               1.   A lump sum distribution; or

               2.   Payments in approximately equal annual installments for a
                    period not to exceed 10 years.

          (c)  Beneficiary Designation. In the event the Participant dies before
               -----------------------
               receiving the entire distribution owned to him, the balance in
               his Deferred Compensation Account on the Participant's date of
               death shall be paid in a lump sum to the beneficiary designated
               by the Participant on his "Beneficiary Designation Form", a copy
               of which is attached hereto as Exhibit C, which must be properly
                                              ---------  
               executed and delivered to the Administrative Committee.

          (d)  Acceleration of Payments. The Company hereby reserves the right
               ------------------------
               to accelerate the payment of any sums specified in the Plan
               without the consent of the Participant, his estate,
               beneficiaries, or any other person claiming through or under him.

          (e)  Incapacity of Beneficiary. If Company shall find that any person
               ------------------------- 
               to whom any payment is payable under the Plan is unable to care
               for his affairs because of illness or accident or is a minor,



 
               any payment due (unless a prior claim therefor shall have been
               made by a duly appointed guardian, committee, or other legal
               representative) may be paid to the spouse, a child, parent, or
               brother or sister, or to any person deemed by the Company have
               incurred expense for such person otherwise entitled to payment,
               in accordance with the applicable provisions of Paragraph (c).
               Any such payment shall be a complete discharge of the Company's
               liabilities under the Plan.

     13.  Trust Not Established.  Nothing contained in the Plan and no action 
          --------------------- 
taken pursuant to the provisions of the Plan shall create or be construed to
create a trust of any kind, or a fiduciary relationship between the Company, its
Board of Directors, officers and employees and any Participant or any other
person. Any assets, whether cash or investments, which the Company may carmark
to pay the amount credited to the Deferred Compensation Account shall continue,
for all purposes, to be a part of the general funds of the Company and the
Participants shall not by virtue of the provisions of the Plan have any property
interest in such funds. The Company may establish one or more trusts, with such
trustees as the Board may approve, for the purpose of providing for the payment
of deferred Compensation hereunder. Such trusts shall be irrevocable but the
assets thereof shall be subject to the claims of the Company's creditors. To the
extent that any deferred Compensation provided under the Plan is actually paid
from any such trust, the Company shall have no further obligations with respect
thereto, but to the extent not so paid, such benefits shall remain the
obligation of and shall be paid by the Company. No Director shall have any
right, title, or interest in or to any investment reserves, accounts, or funds
that the Company may purchase, establish or accumulate to aid in providing
benefits under this Plan. To the extent that any person acquires a right to
receive payments from the Company under the Plan, such right shall be no greater
than the right of any unsecured general creditor of the Company.

     14.  Alienation and Assignment of Benefits.  The right of any Participant 
          -------------------------------------
or any other person to payment of the Deferred Compensation Account under the
Plan shall not be anticipated, alienated, sold, assigned, transferred, pledged,
encumbered, attached or garnished except by will or by the laws or descent and
distribution.

     15.  Not a Contract of Service.  Neither the establishment of, nor the 
          -------------------------
participant or eligibility for participation of any Outside Director in, this
Plan shall be construed to confer any right of tenure on the part of any Outside
Director or any right of nomination, renomination, election or re-election to
the Board of Directors of the Company. The Company shall not incur any liability
for any loss of benefits that might result under this Plan from any failure of
the stockholders to elect or re-elect any Outside Director to the Board of
Directors or any failure of the Board of Directors to nominate any Outside
Director for re-election.


 
          16.  Binding Effect.  The Plan shall be binding upon and inure to the 
               --------------
benefit of the Company, its successors and assigns and the Participant and his 
heirs, executors, and personal representatives.

          17.  No Security in Deferred Compensation Account.  Participants shall
               --------------------------------------------
have the status of general unsecured creditors of the Company and the Plan 
constitutes a mere promise by the Company to make benefit payments in the 
future.  The Plan shall be unfunded for purposes of the Code and for purposes of
Title I of ERISA.

          18.  Governing Law.  The Plan shall be governed by and construed in 
               ------------- 
all respects under the laws of the Commonwealth of Pennsylvania and applicable 
federal law.

          19.  Entire Agreement.  This Plan and the Exhibits attached hereto and
               ----------------
executed by a Participant contain the entire agreement of the parties with 
respect to the subject matter hereof and supersedes all prior contracts, 
agreements understandings and representations relating hereto.  It may not be 
changed orally but only by an amendment in writing in accordance with the terms
hereof.

          20.  Construction.  As used in the Plan, words of masculine gender 
               ------------
shall be construed to include the feminine gender and vice versa.
     
          21.  Administration and Interpretation.  This Plan shall be 
               ---------------------------------
administered by the Administrative Committee consisting of three County 
National Bank Officers: (1) The Chief Executive Officer (2) Senior Trust Officer
and (3) Chief Financial Officer.  The members of the Administrative Committee 
shall not be eligible to participate in the Plan.  The Administrative Committee 
shall have the full power and authority to interpret, construe and administer 
the Plan and to decide any and all matters arising hereunder, including but not 
limited to the right to remedy possible ambiguities, inconsistencies or 
omissions, by general rule or particular decision; provided, that all such 
interpretations, constructions, and decisions shall be applied in a uniform and 
nondiscriminatory manner to all Participants similarly situated.  In addition, 
any interpretation, construction, or decision made by the Administrative 
Committee shall be final, conclusive and binding upon all persons who have or 
who claim to have any interest in or under the Plan.

          22.  Indemnification.  The members of the Administrative Committee and
               ---------------
its agents, and officers, directors and employees of the Company shall be
indemnified and held harmless by the Company to the fullest extent now or
hereafter permitted by law against and from any and all loss, cost, liability or
expense, including attorneys' fees, fines, civil penalties and excise taxes that
may be imposed upon or reasonably incurred by them in connection with or
resulting from any actual or threatened civil, criminal, administrative or
investigative claim, action, suit or proceeding to which they may be a party or
in which they may be involved by reason of any action taken or failure to act
under this Plan and against and from any and all



 

amounts paid by them in settlement (with the Company's written approval) or paid
by them in satisfaction of a judgment in any such action, suit or proceeding.  
The indemnification provided by this paragraph shall continue for persons who 
have ceased to be members or agents of the Administrative Committee, and to
former directors, officers and employees of the Company, and shall inure to the
benefit of the heirs, executors and administrators of persons entitled to
indemnity hereunder. This paragraph shall not be applicable to any person if the
loss, cost, liability or expense is finally judicially determined to be due to
such person's recklessness or willful misconduct.

          23.  Compliance With Code and ERISA.  The parties intend that the Plan
               ------------------------------
comply with the provisions of the Code, ERISA and the Regulations in effect 
thereunder at the time of its execution.  If, at a later date, the laws of the 
United States or the Commonwealth of Pennsylvania are construed in such a way as
to make this Plan null and void, it shall be given effect in a manner that shall
best carry out the Company's purposes and intentions.

          24.  Severability.  In the event any provision of the Plan shall be 
               ------------
held invalid or illegal for any reason, such illegality or invalidity shall not 
affect the remaining parts of the Plan, but the Plan shall be construed and 
enforced as if the illegal or invalid provision had never been inserted, and the
Company shall have the privilege and opportunity to correct and remedy such 
questions of illegality or invalidity by amendment as provided in the Plan.

          25.  Expenses.  The expenses of administering the Plan shall be borne 
               --------
by the Company.

          26.  Amendment and Termination.  The Company expects to continue the 
               -------------------------
Plan indefinitely, but specifically reserves the right, in the sole and 
unfettered discretion of its Board of Directors, at any time, to amend, in whole
or in part, any or all of the provisions of the Plan and to terminate the Plan 
in whole or in part, provided, however, that no such amendment or termination 
shall adversely affect any rights of an Outside Director to receive the deferred
Compensation which had accrued on his behalf on account of his service as an 
Outside Director prior to such amendment or termination.

          IN WITNESS WHEREOF, the Company has caused this Plan to be adopted as 
of the _____ day of _____, 1997.
