        (i)  On the Effective Date, each option (a "CIB Option") to purchase one
or more shares of CIB Common Stock issued by CIB and outstanding on the
Effective Date, whether or not such option is exercisable on the Effective Date,
shall, by virtue of the Merger, cease to be outstanding and be converted into an
option to purchase the number of shares of NPB Common Stock which the
optionholder would have been entitled to receive in the Merger had such option
been exercised in full immediately prior to the Effective Date, at an exercise
price per share of NPB Common Stock equal to the per share exercise price of the
CIB Option divided by the Exchange Ratio, and having other terms and conditions
           ----------
identical to those of the option exchanged (including forfeiture, acceleration
and expiration date provisions). The adjustment provided herein with respect to
any options which are "incentive stock options", as defined in Section 422 of

with Section 424(a) of the IRC.

        (ii) As soon as practicable after the Effective Date, NPB shall deliver

rights pursuant to the CIB Stock Option Plans, and the agreements evidencing the
grants of such CIB Options shall continue in effect on the same terms and
conditions (subject to the adjustments required by this Section 1.02(f) after
giving effect to the Merger and the terms of the CIB Stock Option Plans). NPB
shall comply with the terms of the CIB Stock Option Plans and shall take such
reasonable steps as are necessary or required by, and subject to the provisions
of, such CIB Stock Option Plans, to have the CIB Options, if any, which
qualified as "incentive stock options" prior to the Effective Date, continue to
qualify as "incentive stock options" after the Effective Date.

          (iii) NPB shall take all corporate action necessary to

                                       9

reserve for issuance a sufficient number of shares of NPB Common Stock for
delivery upon exercise of CIB Options in accordance with this Agreement.
Promptly after the Effective Date, NPB shall file a registration statement on
Form S-3 or Form S-8, as the case may be (or any successor other appropriate
forms), with respect to the shares of NPB Common Stock subject to such options
and shall use commercially reasonable efforts to maintain the effectiveness of
such registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained thereon) for so long as such
options remain outstanding. With respect to those individuals who, subsequent to
the Merger, will be subject to the reporting requirements under Section 16(a) of
the Exchange Act, where applicable, NPB shall administer the CIB Stock Option
Plans in a manner consistent with the exemptions provided by Rule 16b-3
promulgated under the Exchange Act.

  (g) Surrender and Exchange of CIB Stock Certificates.
      ------------------------------------------------

        (i)  Each holder of shares of CIB Common Stock who surrenders to NPB the
certificate or certificates representing such shares (each, a "CIB Certificate")

the Effective Date, a certificate for the number of whole shares of NPB Common
Stock into which such holder's shares of CIB Common Stock have been converted by
the Merger, together with a check for cash in lieu of any fractional share in
accordance with Section 1.02(e)(ii)(C) hereof (the "Merger Consideration").

        (ii) Each certificate for shares of NPB Common Stock (each, an "NPB
Certificate") issued in exchange for CIB Certificates pursuant to Section
1.02(g)(i) hereof shall be dated the Effective Date and be entitled to dividends
and all other rights and privileges pertaining to such shares of stock from the

the Effective Date, evidence solely the right to receive NPB Certificates
pursuant to Section 1.02(g)(i) hereof and a check for cash in lieu of any
fractional share in accordance with Section 1.02(e)(ii)(C) hereof. If a CIB
Certificate is exchanged on a date following one or more record dates for the
payment of dividends or any other distribution on shares of NPB Common Stock,
NPB shall pay to such shareholder cash in an amount equal to dividends payable
on such shares of NPB Common Stock and pay or deliver any other distribution to
which such shareholder is entitled. No interest shall accrue or be payable in
respect of dividends or any other distribution otherwise payable under this
Section 1.02(g)(ii) upon surrender of CIB Certificates. Notwithstanding the
foregoing, no party hereto shall be liable to any holder of CIB Common Stock for
any amount paid in good faith to a public official or agency pursuant to any
applicable abandoned property, escheat or similar law. Until such time as CIB
Certificates are surrendered to NPB for exchange, NPB shall

                                       10
<PAGE>

have the right to withhold dividends or any other distributions on the shares of
NPB Common Stock issuable to such shareholder.

1.02(g) must be endorsed in blank by the registered holder thereof or
accompanied by a power of attorney to transfer such shares endorsed in blank by
such holder.

        (iv) Upon the Effective Date, the stock transfer books for CIB Common
Stock will be closed and no further transfers of CIB Common Stock will
thereafter be made or recognized. All CIB Certificates surrendered pursuant to
this Section 1.02(g) will be cancelled.

        (v)  As soon as reasonably practicable after the Effective Date, NPB
shall cause NPBank or another institutional entity selected by NPB, as exchange
agent (the "Exchange Agent"), to mail to each holder of a CIB Certificate:

             (A)  a letter of transmittal which shall specify that delivery
shall be effected, and risk of loss and title to the CIB Certificates shall
pass, only upon delivery of the CIB Certificates to the Exchange Agent, and
which letter shall be in customary form and have such other provisions as NPB
reasonably may specify; and

             (B)  instructions for effecting the surrender of such CIB
Certificates in exchange for the applicable Merger Consideration.

Upon surrender of a CIB Certificate to the Exchange Agent together with such
letter of transmittal, duly executed and completed in accordance with the
instructions thereto, and such other documents as reasonably may be required by
the Exchange Agent, the holder of such CIB Certificate shall be entitled to
receive in exchange therefor:

             (X)  one or more shares of NPB Common Stock representing, in the
aggregate, the whole number of shares that such holder has the right to receive
pursuant to Section 1.02(e) (after taking into account all shares of CIB Common
Stock then held by such holder); and

             (Y)  a check in the amount equal to the cash that such holder has
the right to receive pursuant to the provisions of this Section 1.02, including
cash in lieu of any fractional shares and dividends and other distributions
pursuant to Section 1.02(g)(ii).

In the event of a transfer of ownership of CIB Common Stock which is not
registered in the transfer records of CIB, one or more NPB

                                       11
<PAGE>

Certificates evidencing, in the aggregate, the proper number of shares of NPB
Common Stock, a check in the proper amount of cash in lieu of any fractional
shares and any dividends or other distributions to which such holder is entitled
pursuant to Section 1.02(g)(ii), may be issued with respect to such CIB Common
Stock to such a transferee if the CIB Certificate representing such shares of
CIB Common Stock is presented to the Exchange Agent, accompanied by all
documents required to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid.

  (h) Anti-Dilution Provisions.  If NPB shall, at any time before the Effective
      ------------------------
Date:

          (i) issue a dividend in shares of NPB Common Stock;

with the execution of this Agreement, NPB shall cause NPBank to execute, and CIB

is a party to any transaction (including any loan or other credit accommodation
but excluding deposits in the ordinary course of business) with any Affiliate of
NPB or any NPB Subsidiary, and all such transactions were made on substantially
the same terms, including interest rates and collateral, as those prevailing at
the time for comparable transactions with other "persons" (as defined in Section

with respect to variations in such terms as would not, individually or in the
aggregate, have a Material Adverse Effect.

Subsidiary is presently in default or, during the three-year period prior to the

evidenced by notes, agreements or other evidences of indebtedness which are
true, genuine and correct, and to the extent secured, are secured by valid liens

the failure to satisfy the foregoing standards would not have a Material Adverse
Effect.

  3.20  Accounting for the Merger; Reorganization.  As of the date hereof, NPB
        -----------------------------------------

"pooling of interests" accounting treatment under generally accepted accounting
principles, or as a "reorganization" under Section 368(a) of the IRC.

        --------------------
other processing capabilities utilized by and material to the operations of NPB

involving all calendar dates correctly, including single century formulas and
multi-century formulas, all leap years, and all dates on or after January 1,
2000, including February 29, 2000.  All computer systems of NPB or any NPB

  (c)  Undertakings of NPB.
       -------------------

     (i)  Employees, Severance Policy.
          ---------------------------

        (A)  NPB will endeavor to continue the employment of all current
employees of CIB or any CIB Subsidiary in positions that will contribute to the
successful performance of the combined organization. Where there is a
coincidence of responsibilities, NPB will try to reassign the affected
individual to a needed position that utilizes the skills and abilities of the
individual. If that is impracticable or if NPB elects to eliminate a position,
NPB will make severance payments to the displaced employee as set forth in this
Section 4.07(c)(i). NPB will also make severance payments to an employee who
declines a position that requires re-location more than 40 miles from his
current place of employment.

        (B)  Subject to the following minimum and maximum benefits, NPB will
grant an eligible employee one week of severance pay (at his then current pay
rate) for each year of an employee's service with CIB or any CIB Subsidiary
prior to the employment termination date. The minimum benefit shall be four
weeks' salary for full-time exempt and nonexempt employees, which will be pro-
rated for part-time employees. The maximum severance benefit will be 26 weeks'
salary.

        (C)  All employees of CIB or of any CIB Subsidiary on the date hereof
will be eligible for severance benefits set forth in this Section 4.07(c)(i),
except that:

           (1)  No employee of CIB or of any CIB Subsidiary who shall receive
any payments or benefits pursuant to any "change in control" agreement or
similar plan or right shall be eligible for any severance benefits; and

           (2)  No employee of CIB or of any CIB Subsidiary with an operating
systems conversion support role of any kind shall be eligible for any severance
benefits unless such employee continues in employment for 30 days following the
actual consolidation and conversion of BBank's operating systems with and into
NPBank's operating systems, which, as of the date hereof, is

                                       49
<PAGE>

scheduled to be not later than June 30, 2001.

        (D)  Persons eligible for severance benefits will remain eligible for
such benefits in the event of any termination of employment, other than for
"cause", within six months of the Effective Date. Any person whose employment
with NPB is terminated by NPB without "cause" after six months from the
Effective Date shall receive such severance benefit from NPB as is provided for
in NPB's general severance policy for such terminations (with full credit being
given for each year of service with CIB or any CIB Subsidiary).

        (E)  For purposes of this Section 4.07(c)(i), "cause" means the
employer's good faith reasonable belief that the employee (1) committed fraud,
theft or embezzlement; (2) falsified corporate records; (3) disseminated
confidential information concerning customers, NPB, any NPB Subsidiary or any of
its or their employees; (4) had documented unsatisfactory job performance under
NPB's dismissal policy; or (5) violated NPB's Code of Conduct. The foregoing
definition of "cause" is the definition of "cause" used by NPB and its
Subsidiaries in the ordinary course of its business.

     (ii)  Employee Benefits.
           -----------------

        (A)  As of the Effective Date, each employee of CIB or of any CIB
Subsidiary who becomes an employee of NPB or of any NPB Subsidiary shall be
entitled to full credit for each year of service with CIB or the CIB Subsidiary
for purposes of determining eligibility for participation and vesting, but not
benefit accrual, in NPB's, or as appropriate, the NPB Subsidiary's, employee
benefit plans, programs and policies.

        (B)  The employee benefits provided to former employees of CIB or a CIB
Subsidiary after the Effective Date shall be substantially similar to the
employee benefits, in the aggregate, provided by NPB or its Subsidiaries to
their similarly situated employees. The medical, dental and life insurance
plans, programs or policies, if any, that become applicable to former employees
of CIB or any CIB Subsidiary shall not contain any exclusion or limitation with
respect to any pre-existing condition of any such employees or their dependents.

        (C)  Subject to the foregoing, after the Effective Date, NPB or any NPB
Subsidiary may discontinue, amend or convert to an NPB or an NPB Subsidiary plan
any particular benefit or welfare plan of CIB or any CIB Subsidiary, subject to
such plan's provisions and applicable law.

     (iii) Election of NPBank Directors.
           ----------------------------

                                       50
<PAGE>

        (A)  Upon consummation of the Merger and subject to compliance with all
applicable legal requirements, NPB shall cause NPBank to elect the CIB Nominee
(selected pursuant to Section 1.02(d)(i) hereof) and one other person selected
by CIB's Board of Directors (consistent with the 60 years age limitation
contained in NPBank's Bylaws) and approved by NPB (which approval will not be
unreasonably withheld) (each, a "CIB NPBank Nominee") as directors of NPBank,
effective the Effective Date, to hold office until their successors are elected
and qualified or otherwise in accordance with applicable law, the articles of
association and bylaws of NPBank; and NPB and NPBank shall take all steps
necessary to insure that each CIB NPBank Nominee is re-elected to NPBank's Board
of Directors for each of the five years following the Effective Date if such
person is in office as director of NPBank on the annual election dates.

        (B)  If either CIB NPBank Nominee, or any successor, resigns, dies or is
otherwise removed from NPBank's Board of Directors prior to the end of the fifth
one-year term, the former CIB directors then serving on the Division Board, by a
plurality vote, shall have the right to select (consistent with the 60 years age
limitation contained in NPBank's Bylaws) the successor to such CIB NPBank
Nominee, or any successor, subject to approval of such person by NPB (which
approval will not be unreasonably withheld), and NPB shall take all reasonable
steps to elect such successor to the NPBank Board of Directors.

     (iv) Banking Division, Division Board.
          --------------------------------

        (A)  Upon consummation of the Bank Merger and subject to compliance
with all applicable legal requirements, NPB shall cause NPBank to combine the
assets, branches and operations of BBank with those of NPBank in Berks County,
to create the Berks County Division (the "Division"). The BBank branches located
in Bernville and Shartlesville shall each be operated under a local identity
sign, "Bernville Bank, Division of National Penn Bank".

        (B)  Upon consummation of the Bank Merger, and subject to compliance
with all applicable legal requirements, NPB shall cause NPBank to establish the
"Berks County Division Board of Directors" (the "Division Board"). The Division
Board shall initially consist of the members of CIB's Board of Directors
immediately preceding the Effective Date and various NPB and NPBank executive
officers and other persons as selected by NPB. The Division Board will have
authority to add additional members from time to time. NPB anticipates that the
Division Board will emphasize sales, marketing and expansion relating to the
Division .

        (C)  Non-employee members of the Division Board who are former
directors of CIB shall receive annual cash compensation for service on the
Division Board, in a combination

                                       51
<PAGE>

of an annual fee and Division Board attendance fees, in an aggregate amount not
less than the aggregate amount of directors' fees paid in cash to them by CIB or
any CIB Subsidiary in the year preceding the Effective Date. Other persons who
may be selected for service as non-employee members of the Division Board shall
be compensated in accordance with NPB's standard compensation arrangements for
divisional board members, which is partially fixed and partially incentive-based
compensation. The former CIB directors shall have the option of electing to
receive such NPB standard compensation. Employee members of the Division Board
shall not be separately compensated for serving on such Board. The Division
Board shall have indemnification and insurance coverage no less favorable than
members of NPBank's other divisional advisory boards.

        (D)  NPB shall operate the Division, and maintain the Division Board at
the foregoing compensation level, for a period of at least five years after the
Effective Date, except that this covenant shall expire if and when NPB shall be
acquired or otherwise sold and thereafter the members of NPB's Board of
Directors do not constitute at least 50% of the members of the surviving
corporation's board of directors.

     (v)  Indemnification, Insurance.
          --------------------------

        (A)  NPB shall indemnify, defend, and hold harmless the directors,
officers, employees and agents of CIB (each, an "Indemnified Party") against all
losses, expenses (including reasonable attorneys' fees), claims, damages or
liabilities and amounts paid in settlement arising out of actions or omissions
or alleged acts or omissions (collectively, "Prior Acts") occurring at or prior
to the Effective Date (including the transactions contemplated by this
Agreement) to the fullest extent permitted by the BCL, including provisions
relating to advances of expenses incurred in the defense of any proceeding to
the fullest extent permitted by the BCL upon receipt of any undertaking required
by the BCL. Without limiting the foregoing, in a case (if any) in which a
determination by NPB is required to effectuate any indemnification, NPB shall
direct, at the election of the Indemnified Party, that the determination shall
be made by independent counsel mutually agreed upon between NPB and the
Indemnified Party.

        (B)  NPB shall, and it shall cause NPBank to, keep in effect provisions
in its articles of incorporation or association and bylaws providing for
exculpation of director and officer liability and its indemnification of the
Indemnified Parties to the fullest extent permitted by the BCL, which provisions
shall not be amended except as required by applicable law or except to make
changes permitted by law that would enlarge the Indemnified Parties' right to
indemnification.

                                       52
<PAGE>

        (C)  NPB shall use its reasonable best efforts (and CIB shall cooperate
and assist prior to the Effective Date in these efforts), at no expense to the
beneficiaries, to:

           (1)  maintain directors' and officers' liability insurance ("D&O
Insurance") for the Indemnified Parties with respect to matters occurring at or
prior to the Effective Date, issued by a carrier assigned a claims-paying
ability rating by A.M. Best & Co. of "A (Excellent)" or higher; or

           (2)  obtain coverage for Prior Acts for the Indemnified Parties under
the directors' and officers' liability insurance policy currently maintained by
NPB;

in either case, providing at least the same coverage as the D&O Insurance
currently maintained by CIB and containing terms and conditions which are no
less favorable to the beneficiaries, for a period of at least six (6) years from
the Effective Date; provided, that NPB shall not be obligated to make premium
payments for such six-year period in respect of the D&O Insurance which exceed,
for the portion related to CIB's directors and officers, 150 percent of the
annual premium payments ($6,812) at the date hereof) of CIB's current policy in
effect as of the date of this Agreement (the "Maximum Amount").  If the amount
of the premiums necessary to maintain or procure such insurance coverage exceeds
the Maximum Amount, NPB shall use its reasonable best efforts to maintain the
most advantageous policies of directors' and officers' liability insurance
obtainable for a premium equal to the Maximum Amount.

        (D)  If any claim is made against present or former directors, officers
or employees of CIB or any CIB Subsidiary who are covered or potentially covered
by insurance, neither NPB nor any NPB Subsidiary shall do anything that would
forfeit, jeopardize, restrict or limit the insurance coverage available for that
claim until the final disposition thereof.

        (E)  If NPB or any of its successors or assigns shall consolidate with
or merge into any other person and shall not be the continuing or surviving
person of such consolidation or merger or shall transfer all or substantially
all of its assets to any person, then and in each case, proper provision shall
be made so that the successors and assigns of NPB shall assume the obligations
set forth in this Section 4.07(c)(v).

        (F)  The provisions of this Section 4.07(c)(v) are intended to be for
the benefit of and shall be enforceable by, each Indemnified Party, his or her
heirs and representatives.

        (G)  NPB shall pay all expenses, including

                                       53
<PAGE>

reasonable attorneys' fees, that may be incurred by any Indemnified Party in
enforcing the indemnity and other obligations provided for in this Section
4.07(c)(v).

     (vi) Pooling of Interests; Reorganization.  Through the Closing Date, NPB
          ------------------------------------
shall not take any action which would preclude the Merger from qualifying for
"pooling of interests" accounting treatment under generally accepted accounting
principles or as a "reorganization" within the meaning of Section 368 of the
IRC.

     (vii) Conduct of NPB's Business.  Through the Closing Date, NPB shall use
           -------------------------
its reasonable good faith efforts to preserve its business organization intact,
maintain good relationships with employees, and preserve the good will of
customers of NPB and others with whom business relationships exist.

National Penn Bancshares, Inc.
Philadelphia and Reading Avenues
Boyertown, Pennsylvania 19512

Ladies and Gentlemen:

  National Penn Bancshares, Inc. ("NPB") and Community Independent Bank, Inc.
("CIB") are considering execution of an Agreement dated July 23, 2000 (the
"Agreement").

  Pursuant to the proposed Agreement, and subject to the terms and conditions
set forth therein, (a) NPB will acquire CIB by a merger of CIB with and into
NPB, (b) shareholders of CIB will receive shares of NPB common stock in exchange
for their shares of CIB common stock owned on the closing date, and (c)
optionholders of CIB will receive stock options exercisable for common stock of
NPB in exchange for options exercisable for common stock of CIB outstanding on
the closing date (the foregoing, collectively, the "Merger").

  NPB has required as a condition to its execution and delivery to CIB of the
Agreement, that the undersigned, being a director of CIB, execute and deliver to
NPB this Letter Agreement.

  The undersigned, in order to induce NPB to execute the Agreement, and
intending to be legally bound hereby, irrevocably agrees and represents as
follows:

  1.  The undersigned agrees to vote or cause to be voted for approval of the
Merger all shares of CIB common stock over which the undersigned exercises sole
voting power.

  2.  Through the record date for the meeting of CIB shareholders to vote upon
the Merger and for the period and to the extent provided in Paragraph 6 hereof,
the undersigned agrees not to offer, sell, transfer or otherwise dispose of, or
to permit the offer, sale, transfer or other disposition of, any shares of CIB
common stock over which the undersigned exercises sole voting power.

  3.  The undersigned has sole voting power over the number of shares of CIB
common stock, and holds stock options for the number of shares of CIB common
stock, if any, set forth below opposite the signature line for the undersigned.
NPB recognizes that with respect to any such shares which have been pledged to a

                                       65
<PAGE>

third party, the undersigned will not be able to control the voting or
disposition of such shares in the event of a default.

  4.  The undersigned agrees not to offer, sell, transfer or otherwise dispose
of any shares of NPB common stock received pursuant to the Merger, except:

     (a) at such time as a registration statement under the Securities Act of
1933, as amended ("Securities Act"), covering sales of such NPB common stock is
effective and a prospectus is made available under the Securities Act;

     (b) within the limits, and in accordance with the applicable provisions of,
Rule 145 under the Securities Act ("Rule 145"); or

     (c) in a transaction which, in the opinion of counsel satisfactory to NPB
or as described in a "no-action" or interpretive letter from the staff of the
Securities and Exchange Commission ("SEC"), is not required to be registered
under the Securities Act;

and the undersigned acknowledges and agrees that NPB is under no obligation to
register the sale, transfer or other disposition of NPB common stock by the
undersigned or on behalf of the undersigned, or to take any other action
necessary to make an exemption from registration available.

  5.  NPB shall take all steps necessary to ensure that NPB is in compliance
with all those requirements of Rule 145 with which NPB must comply in order for
the resale provisions of Rule 145(d) to be available to the undersigned.

  6.  Notwithstanding the foregoing, the undersigned agrees not to sell, or in
any other way reduce the risk of the undersigned relative to, any shares of
common stock of CIB or of common stock of NPB, during the period commencing
thirty (30) days prior to the effective date of the Merger and ending on the
date on which financial results covering at least thirty (30) days of post-
Merger combined operations of NPB and CIB have been published within the meaning
of Section 201.01 of the SEC's Codification of Financial Reporting Policies;
provided, however, that excluded from the foregoing undertaking shall be such
sales, pledges, transfers or other dispositions of shares of CIB common stock or
shares of NPB common stock which, in NPB's reasonable judgment, are individually
and in the aggregate de minimis within the meaning of Topic 2-E of the Staff
                     -- -------
Accounting Bulletin Series of the SEC.

  7.  The undersigned agrees that neither CIB nor NPB shall be bound by any
attempted sale of any shares of CIB common stock

                                       66
<PAGE>

or NPB common stock, respectively, and CIB's and NPB's transfer agents shall be
given appropriate stop transfer orders and shall not be required to register any
such attempted sale, unless the sale has been effected in compliance with the
terms of this Letter Agreement; and the undersigned further agrees that the
certificates representing shares of NPB common stock owned by the undersigned
may be endorsed with restrictive legends consistent with the terms of this
Letter Agreement.

  8.  The undersigned represents that he has no plan or intention to offer,
sell, exchange, or otherwise dispose of any shares of common stock of NPB prior
to expiration of the time period referred to in subparagraph 6 hereof.

  9.  The undersigned agrees, if he is an optionholder, to exchange his options
to acquire shares of common stock of CIB for options to acquire such number of
shares of common stock of NPB as he would have acquired if he had exercised such
options immediately prior to consummation of the Merger, and otherwise on the
same terms and conditions as the exchanged CIB options (unless the undersigned
shall have exercised any such option prior to the Merger).

  10.  The undersigned represents that he has the capacity to enter into this
Letter Agreement and that it is a valid and binding obligation enforceable
against the undersigned in accordance with its terms, subject to bankruptcy,
insolvency and other laws affecting creditors' rights and general equitable
principles.

  The parties hereto acknowledge that this Letter Agreement is being executed by
the undersigned in his capacity solely as a shareholder of CIB, and not in any
other capacity (including as a director of CIB), and nothing herein contained
shall derogate from the undersigned's ability to act in such other capacity,
including the exercise of fiduciary duty, even if in conflict with the
foregoing.

  This Letter Agreement may be executed in two or more counterparts, each of
which shall be deemed to constitute an original, but all of which together shall
constitute one and the same Letter.

  This Letter Agreement shall be effective upon acceptance by NPB.



                                       67
<PAGE>

This Letter Agreement shall terminate concurrently with, and automatically upon,
any termination of the Agreement in accordance with its terms, except that any
such termination shall be without prejudice to NPB's rights arising out of any
willful breach or any covenant or representation contained herein.

                                        Very truly yours,

                                       71
<PAGE>

  or used in Section 13(d) of the Exchange Act and the rules and regulations
  thereunder), other than NPB or an affiliate of NPB, acquires beneficial
  ownership (within the meaning of Rule 13d-3 under the Exchange Act) of 10% or
  more of the then outstanding shares of Common Stock (excluding any shares
  eligible to be reported on Schedule 13G of the SEC);

        (ii) a person or group, other than NPB or an affiliate of NPB, publicly
  announces a bona fide proposal (including a written communication that is
  or becomes the subject of public disclosure) for:

           (A)  any merger, consolidation or acquisition of all or substantially
     all the assets or liabilities of CIB, BBank, or any other business
     combination involving CIB or BBank; or

           (B)  a transaction involving the transfer of beneficial ownership of
     securities representing, or the right to acquire beneficial ownership or to
     vote securities representing, 10% or more of the then outstanding shares of
     Common Stock or the then outstanding shares of common stock of BBank,
     (collectively, a "Proposal");

  and thereafter, if such Proposal has not been Publicly Withdrawn (defined
  below) at least 30 days prior to the meeting of shareholders of CIB called to
  vote on the Merger, CIB's shareholders fail to approve the Merger by the vote
  required by applicable law at the meeting of shareholders called for such
  purpose or such meeting has been cancelled;

        (iii) the Board of Directors of CIB shall:

           (A)  fail to recommend the Merger;

           (B)  recommend a Proposal; or

           (C)  have withdrawn or modified in a manner adverse to NPB the
     recommendation of the Board of Directors of CIB with respect to the
     Agreement and thereafter CIB's shareholders fail to approve the Merger by
     the vote required by applicable law at the meeting of shareholders called
     for such purpose or such meeting is not scheduled or has been cancelled; or

        (iv) a person or group, other than NPB or an affiliate of NPB, makes a
  bona fide Proposal and thereafter, but before such Proposal has been Publicly
  Withdrawn, CIB shall have breached any representation, warranty, covenant or
  obligation contained in the Agreement and such breach would

                                       72
<PAGE>

  entitle NPB to terminate the Agreement under Section 6.01(b)(i) of the
  Agreement (without regard to the cure period provided for therein unless such
  cure is promptly effected without jeopardizing consummation of the Merger
  pursuant to the Agreement).

  If more than one of the transactions giving rise to a Triggering Event or a
Preliminary Triggering Event under this Section 2 is undertaken or effected,
then all such transactions shall give rise only to one Triggering Event or
Preliminary Triggering Event, as applicable, which Triggering Event or
Preliminary Triggering Event shall be deemed continuing for all purposes
hereunder until all such transactions are abandoned.

  For purposes of this Section 2, "Publicly Withdrawn" shall mean an
unconditional bona fide withdrawal of the Proposal coupled with a public
announcement of no further interest in pursuing such Proposal or in acquiring
any controlling influence over CIB or in soliciting or inducing any other person
(other than NPB or an affiliate of NPB) to do so.

  Notwithstanding the foregoing, the obligation of CIB to issue Option Shares
upon exercise of the Option shall be deferred (but shall not terminate):

        (i)  until the receipt of all required governmental or regulatory
  approvals or consents necessary for CIB to issue the Option Shares or NPB to
  exercise the Option, or until the expiration or termination of any waiting
  period required by law, or

        (ii) so long as any injunction or other order, decree or ruling issued
  by any federal or state court of competent jurisdiction is in effect which
  prohibits the sale or delivery of the Option Shares, and, in each case,
  notwithstanding any other provision, the Option shall not expire or otherwise
  terminate.

  CIB shall notify NPB promptly in writing of the occurrence of any Triggering
Event or Preliminary Triggering Event known to it, it being understood that the
giving of such notice by CIB shall not be a condition to the right of NPB to
exercise the Option.  CIB will not take any action which would have the effect
of preventing or disabling CIB from delivering the Option Shares to NPB upon
exercise of the Option or otherwise performing its obligations under this Stock
Option Agreement, except to the extent required by applicable securities and
banking laws and regulations.  In the event NPB wishes to exercise the Option,
NPB shall send a written notice to CIB (the date of which is hereinafter
referred to as the "Notice Date") specifying the total number of Option Shares
it wishes to purchase and a place and date

                                       73
<PAGE>

between two and ten business days inclusive from the Notice Date for the closing
of such a purchase (a "Closing"); provided, however, that a Closing shall not
occur prior to two days after the later of receipt of any necessary regulatory
approvals or the expiration of any legally required notice or waiting period, if
any.

  3.  Repurchase of Option by CIB.
      ---------------------------

     (a)  Subject to the last sentence of Section 2(a), at the request of NPB at
any time commencing upon the first occurrence of a Repurchase Event (defined
below) and ending 12 months immediately thereafter, CIB shall repurchase from
NPB (x) the Option and (y) all shares of Common Stock purchased by NPB pursuant
hereto with respect to which NPB then has beneficial ownership. The date on
which NPB exercises its rights under this Section 3 is referred to as the
"Request Date". Such repurchase shall be at an aggregate price (the "Section 3
Repurchase Consideration") equal to the sum of:

        (i)  the aggregate Option Price paid by NPB for any shares of Common
  Stock acquired pursuant to the Option with respect to which NPB then has
  beneficial ownership;

        (ii) the excess, if any, of:

           (A)  the Applicable Price (defined below) for each share of Common
     Stock over:

           (B)  the Option Price (subject to adjustment pursuant to Section 6);

  multiplied by the number of shares of Common Stock with respect to which the
  Option has not been exercised; and

        (iii) the excess, if any, of the Applicable Price over the Option Price
  (subject to adjustment pursuant to Section 6) paid (or, in the case of Option
  Shares with respect to which the Option has been exercised, but the Closing
  has not occurred, payable) by NPB for each share of Common Stock with respect
  to which the Option has been exercised and with respect to which NPB then has
  beneficial ownership, multiplied by the number of such shares.

  (b)  (i)  If NPB exercises it rights under this Section 3, CIB shall, within
ten (10) business days after the Request Date, pay the Section 3 Repurchase
Consideration to NPB in immediately available funds, and contemporaneously with
such payment, NPB shall surrender to CIB the Option and the certificate
evidencing the shares of Common Stock purchased under the Option with respect to
which NPB then has beneficial ownership, and NPB

                                       74
<PAGE>

shall warrant that it has sole record and beneficial ownership of such shares,
and that the same are then free and clear of all liens, claims, charges and
encumbrances of any kind whatsoever.

        (ii) Notwithstanding Section 3(b)((i), to the extent that prior
notification to or approval of any banking agency or department of any federal
or state government, including without limitation the OCC, the FRB, or the
respective staffs thereof (the "Regulatory Authority"), is required in
connection with the payment of all or any portion of the Section 3 Repurchase
Consideration, NPB shall have the ongoing option to revoke its request for
repurchase pursuant to Section 3, in whole or in part, or to require that CIB
deliver from time to time that portion of the Section 3 Repurchase Consideration
that it is not then so prohibited from paying and promptly file the required
notice or application for approval and expeditiously process the same. Each
party shall cooperate with the other in the filing of any such notice or
application and the obtaining of any such approval. In any such case, the ten
(10) business day period of time that would otherwise run pursuant to Section
3(b)(i) for the payment of the portion of the Section 3 Repurchase Consideration
shall run instead from the date on which, as the case may be, any required
notification period has expired or been terminated or such approval has been
obtained and, in either event, any requisite waiting period shall have passed.

        (iii) If any Regulatory Authority disapproves of any part of CIB's
proposed repurchase pursuant to this Section 3, CIB shall promptly give notice
of such fact to NPB. If any Regulatory Authority prohibits the repurchase
pursuant to this Section 3, CIB shall promptly give notice of such fact to NPB.
If any Regulatory Authority prohibits the repurchase in part but not in whole,
then NPB shall have the right (x) to revoke the repurchase request, or (y) to
the extent permitted by such Regulatory Authority, to determine whether the
repurchase should apply to the Option and/or Option Shares and to what extent to
each, and NPB shall thereupon have the right to exercise the Option as to the
number of Option Shares for which the Option was exercisable at the Request Date
less the sum of the number of shares covered by the Option in respect of which
payment has been made pursuant to Section 3(a)(ii) and the number of shares
covered by the portion of the Option (if any) that has been repurchased. NPB
shall notify CIB of its determination under the preceding sentence within five
(5) business days of receipt of notice of disapproval of the repurchase.

  (c) For purposes of this Agreement, the "Applicable Price" means the highest
of:

        (i)  the highest price per share of Common Stock paid for any such share
  by the person or group described in

                                       75
<PAGE>

  Section 3(d)(i);

        (ii) the price per share of Common Stock received by a holder of Common
  Stock in connection with any merger or other business combination transaction
  described in Section 3(d)(ii), (iii) or (iv); or

        (iii) the highest closing sales price per share of Common Stock quoted
  on the American Stock Exchange during the 15 business days preceding the
  Request Date;

provided, however, that in the event of a sale of less than all of CIB's assets,
the Applicable Price shall be the sum of the price paid in such sale for such
assets and the current market value of the remaining assets of CIB as determined
by a nationally- recognized investment banking firm selected by NPB, divided by
the number of shares of Common Stock outstanding at the time of such sale.  If
the consideration to be offered, paid or received pursuant to either of clauses
(i) or (ii) shall be other than in cash, the value of such consideration shall
be determined in good faith by an independent nationally-recognized investment
banking firm selected by NPB and reasonably acceptable to CIB, which
determination shall be conclusive for all purposes of this Agreement.

  (d) As used herein, a "Repurchase Event" shall occur if:

        (i)  any person or group (as those terms are defined or used in Section
  13(d) of the Exchange Act and the rules and regulations thereunder), other
  than NPB or an affiliate of NPB, acquires beneficial ownership (within the
  meaning of Rule 13d-3 under the Exchange Act) of, or the right to acquire
  beneficial ownership of, 25% or more of the then-outstanding shares of Common
  Stock;

        (ii) CIB shall have merged or consolidated with any person, other than
  NPB or an affiliate of NPB, and shall not be the surviving or continuing
  corporation of such merger or consolidation;

        (iii) any person, other than NPB or an affiliate of NPB, shall have
  merged into CIB and CIB shall be the surviving corporation, but, in connection
  with such merger, the then-outstanding shares of Common Stock have been
  changed into or exchanged for stock or other securities of CIB or any other
  person or cash or any other property or the outstanding shares of Common Stock
  immediately prior to such merger shall after such merger represent less than
  50% of the outstanding shares and share equivalents of the surviving
  corporation; or

                                       76
<PAGE>

        (iv) CIB shall have sold or otherwise transferred more than 25% of its
  consolidated assets to any person, other than NPB or an affiliate of NPB.

  4.  Payment and Delivery of Certificates.  At any Closing hereunder:
      ------------------------------------

     (a)  NPB will make payment to CIB of the aggregate price for the Option
Shares so purchased by wire transfer of immediately available funds to an
account designated by CIB;

     (b)  CIB will deliver to NPB a stock certificate or certificates
representing the number of Option Shares so purchased, registered in the name of
NPB or its designee, in such denominations as were specified by NPB in its
notice of exercise; and

     (c)  NPB will pay any transfer or other taxes required by reason of the
issuance of the Option Shares so purchased.

  A legend will be placed on each stock certificate evidencing Option Shares
issued pursuant to this Stock Option Agreement, which legend will read
substantially as follows:

     "The shares of stock evidenced by this certificate have not been the
  subject of a registration statement filed under the Securities Act of 1933, as
  amended (the "Act"), and declared effective by the Securities and Exchange
  Commission. These shares may not be sold, transferred or otherwise disposed of
  prior to such time unless Community Independent Bank, Inc. receives an opinion
  of counsel acceptable to it stating that an exemption from the registration
  provisions of the Act is available for such transfer."

  5.  Registration Rights.
      -------------------

     (a)  Upon or after the occurrence of a Triggering Event and upon receipt of
a written request from NPB, CIB shall prepare and file as soon as practicable a
registration statement under the Securities Act of 1933 (the "Securities Act")
with the SEC covering such number of Option Shares as NPB shall specify in its
request, and CIB shall use its best efforts to cause such registration statement
to be declared effective in order to permit the sale or other disposition of the
Option Shares; provided that:

        (i)  NPB shall in no event have the right to have more than one such
  registration statement become effective;

        (ii) CIB shall not be required to prepare and file any such registration
  statement in connection with any proposed sale with respect to which
  counsel to CIB delivers

                                       77
<PAGE>

  to CIB and to NPB its opinion to the effect that no such filing is required
  under applicable laws and regulations with respect to such sale or
  disposition; and

        (iii) CIB may delay any registration of Option Shares for a period not
  exceeding 90 days in the event that CIB shall in good faith determine that any
  such registration would adversely affect an offering or contemplated offering
  of securities by CIB. NPB shall provide all information reasonably requested
  by CIB for inclusion in any registration statement to be filed hereunder.

In connection with such filing, CIB shall use its reasonable best efforts to
cause to be delivered to NPB such certificates, opinions, accountant's letters
and other documents as NPB shall reasonably request and as are customarily
provided in connection with the registration of securities under the Securities
Act.  CIB shall provide to NPB such number of copies of the preliminary
prospectus and final prospectus and any amendments and supplements thereto as
NPB may reasonably request.

     (b)  All reasonable expenses incurred by CIB in complying with the
provisions of this Section 5, including, without limitation, all registration
and filing fees, reasonable printing expenses, reasonable fees and disbursements
of counsel for CIB and blue sky fees and expenses, shall be paid by CIB.
Underwriting discounts and commissions to brokers and dealers relating to the
Option Shares, fees and disbursements of counsel to NPB and any other expenses
incurred by NPB in connection with such filing shall be borne by NPB.

     (c)  In connection with any filing under this Section 5, CIB shall
indemnify and hold NPB harmless against any losses, claims, damages or
liabilities, joint or several, to which NPB may become subject, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any preliminary or final registration statement or
any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading; and
CIB will reimburse NPB for any legal or other expense reasonably incurred by NPB
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that CIB will not be liable in any case
to the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such preliminary or final registration statement or
such amendment or supplement thereto in reliance upon and in conformity with
written information furnished by or on

                                       78
<PAGE>

behalf of NPB specifically for use in the preparation of such preliminary or
final registration statement or such amendment or supplement thereto.

     (d)  NPB will indemnify and hold harmless CIB to the same extent as set
forth in the immediately preceding sentence but only with reference to written
information furnished by or on behalf of NPB for use in the preparation of such
preliminary or final registration statement or such amendment or supplement
thereto; and NPB will reimburse CIB for any legal or other expense reasonably
incurred by CIB in connection with investigating or defending any such loss,
claim, damage, liability or action.

     (e)  Notwithstanding any provision of Sections 5(c) or 5(d), no
indemnifying party shall be liable for any settlement effected without its prior
written consent.

  6.  Adjustment Upon Changes in Capitalization.  In the event of any change in
      -----------------------------------------
the Common Stock by reason of stock dividends, split-ups, recapitalizations,
combinations, conversions, divisions, exchanges of shares or the like, then the
number and kind of Option Shares and the Option Price shall be appropriately
adjusted.

  7.  Filings and Consents.  Each of NPB and CIB will use its reasonable best
      --------------------
efforts to make all filings with, and to obtain consents of, all third parties
and governmental authorities necessary to the consummation of the transactions
contemplated by this Stock Option Agreement.  Within 10 days from the date
hereof, NPB shall file a report of beneficial ownership on Form 13D with the SEC
under the Exchange Act which discloses the rights of NPB hereunder.

8.  Representations and Warranties of CIB.  CIB hereby represents and warrants
    -------------------------------------
to NPB as follows:

     (a)  Due Authorization.  CIB has full corporate power and authority to
          -----------------
execute, deliver and perform this Stock Option Agreement and all corporate
action necessary for execution, delivery and performance of this Stock Option
Agreement has been duly taken by CIB. This Stock Option Agreement constitutes a
legal, valid and binding obligation of CIB, enforceable against CIB in
accordance with its terms (except as may be limited by applicable bankruptcy,
insolvency and similar laws affecting creditors' rights generally and subject,
as to enforceability, to general principles of equity).

     (b)  Authorized Shares.  CIB has taken all necessary corporate action to
          -----------------
authorize and reserve for issuance all shares of Common Stock that may be issued
pursuant to any exercise of the Option.

                                       79
<PAGE>

  9.  Representations and Warranties of NPB.  NPB hereby represents and warrants
      -------------------------------------
to CIB that NPB has full corporate power and authority to execute, deliver and
perform this Stock Option Agreement and all corporate action necessary for
execution, delivery and performance of this Stock Option Agreement has been duly
taken by NPB.  This Stock Option Agreement constitutes a legal, valid and
binding obligation of NPB, enforceable against NPB in accordance with its terms
(except as may be limited by applicable bankruptcy, insolvency and similar laws
affecting creditors' rights generally and subject, as to enforceability, to
general principles of equity).

  10.  Specific Performance.  The parties hereto acknowledge that damages would
       --------------------
be an inadequate remedy for a breach of this Stock Option Agreement and that the
obligations of the parties hereto shall be specifically enforceable.

  11.  Entire Agreement.  This Stock Option Agreement and the Agreement
       ----------------
constitute the entire agreement between the parties with respect to the subject
matter hereof and supersede all other prior agreements and understandings, both
written and oral, among the parties or any of them with respect to the subject
matter hereof.

  12.  Assignment or Transfer.  NPB may not sell, assign or otherwise transfer
       ----------------------
its rights and obligations hereunder, in whole or in part, to any person or
group of persons other than to an NPB subsidiary.  NPB represents that it is
acquiring the Option for NPB's own account and not with a view to, or for sale
in connection with, any distribution of the Option or the Option Shares.  NPB is
aware that neither the Option nor the Option Shares is the subject of a
registration statement filed with, and declared effective by, the SEC pursuant
to Section 5 of the Securities Act, but instead each is being offered in
reliance upon the exemption from the registration requirement provided by
Section 4(2) of the Securities Act and the representations and warranties made
by NPB in connection therewith.

  13.  Amendment of Stock Option Agreement.  By mutual consent of the parties
       -----------------------------------
hereto, this Stock Option Agreement may be amended in writing at any time, for
the purpose of facilitating performance hereunder or to comply with any
applicable regulation of any governmental authority or any applicable order of
any court or for any other purpose.

  14.  Validity.  The invalidity or unenforceability of any provision of this

Stock Option Agreement shall not affect the validity or enforceability of any
other provisions of this Stock Option Agreement, which shall remain in full
