            (g) Surrender and Exchange of Heritage and BCB Stock Certificates.
                ------------------------------------------------------------- 

                (i)  Exchange of Certificates.  Each holder of shares of 
                     ------------------------
Heritage Common Stock or BCB Common Stock who surrenders to the Holding Company
(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 Holding Company Common Stock into which such holder's shares of Heritage
Common Stock or BCB Common Stock have been converted pursuant to the
Consolidation, together with a check for cash in lieu of any fractional share in
accordance with Section 1.02(e)(i)(D) or Section 1.02(e)(ii)(D) hereof, as the
case may be.

                (ii) Rights Evidenced by Certificates.  Each certificate for 
                     -------------------------------- 
shares of Holding Company Common Stock issued in exchange for certificates for
Heritage Common Stock or BCB Common Stock pursuant to Section 1.02(g)(i) hereof
will be dated the Effective Date and be entitled to dividends and all other
rights and privileges pertaining to Holding Company Common Stock from and after
the Effective Date. Until surrendered, each certificate theretofore evidencing
shares of Heritage Common Stock or BCB Common Stock, from and after the
Effective Date, will evidence solely the right to receive certificates for
shares of Holding Company Common Stock 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)(i)(D) or Section 1.02(e)(ii)(D), as the case may be. If certificates for
shares of Heritage Common Stock or BCB Common Stock are exchanged for Holding
Company 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 Holding
Company Common Stock, the Holding Company will pay cash in an amount equal to
dividends theretofore payable on such Holding Company Common Stock and pay or
deliver any other distribution to which holders of shares of Holding Company
Common Stock have theretofore become entitled. Upon surrender of certificates
for shares of Heritage Common Stock or BCB Common Stock in exchange for
certificates for Holding Company Common Stock, the Holding Company also shall
pay any dividends to which such holder of Heritage Common Stock, in the case of
a holder of BCB Common Stock, may be entitled as a result of the declaration of
a dividend on the Heritage Common Stock or BCB Common Stock by Heritage or BCB
in accordance with the terms of this Agreement with a record

                                      13
<PAGE>
 
date prior to the Effective Date and a payment date after the Effective Date.
No interest will accrue or be payable in respect of dividends or cash otherwise
payable under this Section 1.02(g) upon surrender of certificates for shares of
Heritage Common Stock or BCB Common Stock.  Notwithstanding the foregoing, no
party hereto will be liable to any holder of Heritage Common Stock or any holder
of BCB 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 certificates for shares of Heritage Common Stock or BCB
Common Stock are surrendered by a BCB or Heritage shareholder to the Holding
Company for exchange, the Holding Company shall have the right to withhold
dividends or any other distributions on the shares of Holding Company Common
Stock issuable to such shareholder.

          (iii)  Exchange Procedures.  Each certificate for shares of Heritage

Common Stock delivered for exchange under this Section 1.02(g) 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 Holding Company
Common Stock for which certificates will be issued pursuant to this Section
1.02(g) will be computed on the basis of the aggregate number of shares
represented by the certificates so surrendered.  If shares of Holding Company
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 Holding Company 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 Heritage Common Stock or BCB Common Stock which are
surrendered.  As promptly as practicable after the Effective Date, the Holding
Company shall send or cause to be sent to each shareholder of record of Heritage
Common Stock or BCB Common Stock transmittal materials for use in exchanging
certificates representing Heritage Common Stock for certificates representing
Holding Company Common Stock into which the Heritage Common Stock or BCB Common
Stock have been converted in the Consolidation.  Certificates representing
shares of Holding Company Common Stock and checks for cash in lieu of fractional
shares shall be mailed to former shareholders of Heritage and BCB as soon as
reasonably possible but in no event later than thirty (30) business days
following the receipt of certificates representing former shares of Heritage
Common Stock or BCB Common Stock duly endorsed or accompanied by the materials

                                      14
<PAGE>
 
  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 Heritage and
                 -------------------------------------------------------------
  BCB Certificates.  Upon the Effective Date, the stock transfer books for
  ----------------                                                        
  Heritage Common Stock and BCB Common Stock will be closed and no further
  transfers of shares of Heritage Common Stock or BCB Common Stock will
  thereafter be made or recognized. All certificates for shares of Heritage
  Common Stock and BCB Common Stock surrendered pursuant to this Section 1.02(g)
  will be cancelled by the Holding Company.

       (h) Anti-Dilution Provisions.  If, Heritage or BCB has, at any time

shares of Heritage Common Stock or BCB Common Stock, (B) combined the
outstanding shares of Heritage Common Stock or BCB Common Stock into a smaller
number of shares, (C) subdivided the outstanding shares of Heritage Common Stock
or BCB Common Stock, or (D) reclassified the shares of Heritage Common Stock or
BCB Common Stock, then the number of shares of Holding Company Common Stock to
be delivered to Heritage or BCB shareholders who are entitled to receive shares
of Holding Company Common Stock in exchange for shares of Heritage Common Stock
or BCB Common Stock shall be adjusted so that each Heritage or BCB shareholder
shall be entitled to receive such number of shares of Holding Company Common
Stock as such shareholder would have been entitled to receive if the Effective
Date had occurred prior to the happening of such event.  (By way of
illustration, if BCB or Heritage shall declare a stock dividend of 7% payable
with respect to a record date on or prior to the Effective Date and the
conditions set forth above are satisfied, the BCB Exchange Ratio or the Heritage
Exchange Ratio, as the case may be, shall be adjusted downward by 7%).

          (a) Heritage and the Heritage Subsidiaries have good and, as to real
property, marketable title to all assets and properties owned by Heritage or any
Heritage Subsidiary in the conduct of their businesses, whether such assets and
properties are real or personal, tangible or intangible, including assets and
property reflected in the balance sheets contained in the Heritage Regulatory
Reports and in the Heritage 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 which secure repurchase agreements and liabilities for
borrowed money, (ii) statutory liens for amounts not yet delinquent or which are
being contested in good faith and (iii) items permitted under Article IV.
Heritage and the Heritage Subsidiaries, as lessee, have the right under valid
and subsisting leases of real and

exceeds the amount of the debt secured thereby.

          (c) Heritage and the Heritage Subsidiaries currently maintain
insurance considered by Heritage to be reasonable for their respective
operations and similar in scope and coverage to that maintained by other
businesses similarly engaged.  Neither Heritage nor any Heritage 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 policies of insurance will be substantially

of insurance and no notices have been given by Heritage or Heritage National
Bank under such policies.  All such insurance is valid and enforceable and in
full force and effect, and within the last three years Heritage 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.

                     -----                                                      
to BCB true and complete copies of all employee pension benefit plans which it
currently maintains within the meaning of ERISA Section 3(2), including profit
sharing plans, employee stock ownership plans, deferred compensation and
supplemental income plans, supplemental executive retirement plans, severance
plans, policies and agreements, group insurance plans, and all other employee
welfare benefit plans within the meaning of ERISA Section 3(1) (including, if
applicable, vacation pay, sick leave, short-term disability, long-term
disability, and medical plans) and all other employee benefit plans, policies,
agreements and arrangements, all of which are set forth in the Heritage
                                                               --------
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 Heritage or any
Heritage Subsidiary, 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 such plans.  To the best
of Heritage's knowledge, neither Heritage, any Heritage Subsidiary nor any
pension plan maintained by Heritage or any Heritage Subsidiary, 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) which
liability has resulted in or will result in a Material Adverse Effect with
respect to Heritage, 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 occurred with respect to
any such pension plan.  With respect to each of such plans that is subject to
Title IV of ERISA, the fair market value of the assets under such plan exceeds
the present value of the accrued benefits liability as of the end of the most
recent plan year with respect to such plan calculated on the basis of the actual
assumptions used in the most recent actuarial valuation for such plan.  Neither
Heritage nor any Heritage Subsidiary has 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 Heritage'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
Heritage'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
Heritage or any Heritage Subsidiary that would result in the imposition,
directly or

                                      24
<PAGE>
 
indirectly, of an excise tax under IRC Section 4975 or other penalty under ERISA
or the IRC, which, individually or in the aggregate, has resulted in or will
result in a Material Adverse Effect with respect to Heritage.  Heritage and the
Heritage Subsidiaries comply with the continuation coverage rules applicable to
its group health plan(s) for covered employees and "qualified beneficiaries" of
covered employees (as defined in IRC Section 4980B(g)) 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.  Neither Heritage nor any
Heritage Subsidiary is aware of any existing or contemplated audit of any of its
employee benefit plans by the Internal Revenue Service or U.S. Department of
Labor.

       Section 3.09  Ownership of Property; Insurance Coverage.
                     ----------------------------------------- 

          (a) BCB and the BCB Subsidiaries have good and, as to real property,
marketable title to all assets and properties owned by BCB or any of its
Subsidiaries in the conduct of their businesses, whether such assets and
properties are real or personal, tangible or intangible, including assets and
property reflected in the balance sheets contained in the BCB Regulatory Reports
and in the BCB 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 repurchase agreements and liabilities for borrowed
money, (ii) statutory liens for amounts not yet delinquent or which are being
contested in good faith, and (iii) items permitted under Article IV.  BCB and
the BCB Subsidiaries, as lessee, have the right under valid and subsisting
leases of real and personal properties used by BCB and its Subsidiaries in the
conduct of their businesses to occupy and use all such properties as presently
occupied and used by each of them.  Except as set forth in the BCB Disclosure
                                                               --- ----------
Schedule, such existing leases and commitments to lease constitute or will
- --------                                                                  
constitute operating leases for both tax and financial accounting purposes and
the lease expense and minimum rental commitments with respect to such leases and
lease commitments are as disclosed in the notes to the BCB Financials.

          (b) With respect to all agreements pursuant to which BCB or any BCB
Subsidiary has purchased securities subject to an agreement to resell, if any,
BCB or such BCB Subsidiary, as the case may be, has a valid, perfected first
lien or security interest in the securities or other collateral securing the
repurchase agreement, and the value of such collateral equals or exceeds the
amount of the debt secured thereby.

          (c) BCB and the BCB Subsidiaries currently maintain insurance in
amounts considered by BCB to be reasonable for their respective operations, and
such insurance is similar in scope and coverage to that maintained by other
businesses similarly engaged.  Neither BCB nor any BCB 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 BCB or Berks County Bank under such policies.  All
such insurance is valid and enforceable and in full force and effect, and within
the last three years BCB 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.

there are no pending or, to the best of BCB's knowledge, threatened legal,
administrative, arbitration or other proceedings, claims, actions or
governmental investigations or inquiries of any nature (i) against BCB or any
BCB Subsidiary, (ii) to which BCB's or any BCB Subsidiary's assets are or may be
subject, (iii) challenging the validity or propriety of any of the transactions

individually or in the aggregate, could not be reasonably expected to have a
Material Adverse Effect on BCB.

       Section 3.11  Compliance With Applicable Law.
                     ------------------------------ 

          (a) BCB and the BCB Subsidiaries hold all licenses, franchises,
permits and authorizations 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 on BCB.

          (b) Neither BCB nor any BCB Subsidiary has received any notification
or communication from any Regulatory Authority (i) asserting that BCB or any BCB
Subsidiary 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 BCB or any BCB Subsidiary; (iii) requiring or threatening to require BCB or
any BCB Subsidiary, or indicating that BCB or any BCB Subsidiary 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 BCB or any BCB Subsidiary,
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 BCB or any BCB Subsidiary, 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").  Neither BCB nor any BCB
Subsidiary has consented to or entered into any Regulatory Agreement, except as
heretofore disclosed to Heritage.

       Section 3.12  Information to be Supplied.  The information to be supplied
                     --------------------------

Prospectus/Proxy Statement)

                                      34
<PAGE>
 
will not, at the time the Registration Statement is declared effective pursuant
to the Securities Act and as of the date the Prospectus/Proxy Statement is
mailed to shareholders of BCB and Heritage and up to and including the date(s)
of the meetings of shareholders of BCB and Heritage to which such
Prospectus/Proxy Statement relates, 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 BCB for inclusion in the Applications will, at the time such documents are
filed with any Regulatory Authority and up to and including the date(s) of the
obtainment of any required regulatory approvals or consents, be accurate in all
material aspects.

       Section 3.13  ERISA.  BCB has previously delivered or made available to
                     -----                                                    
Heritage true and complete copies of the employee pension benefit plans which it
currently maintains within the meaning of ERISA Section 3(2), including profit
sharing plans, stock purchase plans, deferred compensation and supplemental
income plans, supplemental executive retirement plans, severance plans, policies
and agreements, group insurance plans, and all other employee welfare benefit
plans within the meaning of ERISA Section 3(1) (including, if applicable,
vacation pay, sick leave, short-term disability, long-term disability, and
medical plans), and all other employee benefit plans, policies, agreements and
arrangements, all of which are set forth on the BCB 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 BCB or any BCB Subsidiary, 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 such plans.  To the best of BCB's knowledge, neither BCB, any BCB
Subsidiary, nor any pension plan maintained by BCB or any BCB Subsidiary, 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) which liability has resulted in or will result in a Material Adverse
Effect with respect to BCB, 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 occurred with respect to
any such pension plan.  With respect to each of such plans that is subject to
Title IV of ERISA, the fair market value of the assets under such plan exceeds
the present value of the accrued benefits liability as of the end of the most
recent plan year with respect to such plan calculated on the basis of the actual
assumptions used in the most recent actuarial valuation for such plan.  Neither
BCB nor any BCB Subsidiary has incurred or is subject to any liability under
ERISA Section 4201 for a complete or partial

                                      35
<PAGE>
 
withdrawal from a multi-employer plan.  To the best of BCB'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 BCB'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 BCB or any BCB Subsidiary that would result in the imposition,
directly or indirectly, of an excise tax under IRC Section 4975 or other penalty
under ERISA or the IRC, which individually or in the aggregate, has resulted in
or will result in a Material Adverse Effect with respect to BCB.  BCB and the
BCB Subsidiaries comply with the continuation coverage rules applicable to its
group health plan(s) for covered employees and "qualified beneficiaries" of
covered employees (as defined in IRC Section 4980B(g)), 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.  Neither BCB nor any BCB
Subsidiary is aware of any existing or contemplated audit of any of its employee
benefit plans by the Internal Revenue Service or U.S. Department of Labor.

engagement of Janney Montgomery Scott Inc. in connection with the transactions
contemplated by this Agreement, neither BCB nor any BCB Subsidiary, 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 transaction other than
the Consolidation, or, except for its  commitments disclosed in the BCB
                                                                    ---

commissions to any such person in connection with the transactions contemplated
by this Agreement or in connection with any transaction other than the
Consolidation, which has not been reflected in the BCB Financials.  The BCB
                                                                        ---
Disclosure Schedule shall contain as an exhibit the engagement letter between

BCB and Janney Montgomery Scott Inc.

       Section 3.15  Securities Documents.  BCB has delivered to Heritage copies
                     --------------------                                       
of its (i) annual reports on SEC Form 10-KSB for the years ended December 31,
1996, 1995 and 1994, (ii) quarterly reports on SEC Form 10-QSB for the quarters
ended March 31, 1997, June 30, 1997 and September 30, 1997 and (iii) proxy
materials used in connection with its annual meetings of shareholders held in
1997, 1996 and 1995.  Such reports and such proxy materials complied, at the
time filed with the SEC, in all material respects, with the Exchange Act and the
applicable rules and regulations of the SEC.

BCB nor any BCB Subsidiary, nor any properties owned or operated by BCB or any
BCB Subsidiary 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 BCB.  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 BCB, threatened, relating to the liability of any property owned or
operated by BCB or any BCB Subsidiary under any Environmental Law.

be shown, on the balance sheets contained in the BCB Financials have been, and
will be, established in accordance with the requirements of GAAP and all
applicable regulatory criteria.

(iii) in the footnotes to the BCB Financials, BCB is not 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 BCB (except a
BCB Subsidiary); and all such transactions (a) were made in the ordinary course
of business, (b) were 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.  Except as set
forth on the BCB Disclosure Schedule, no loan or credit accommodation to any
             -----------------------                                        
Affiliate of BCB 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.  Neither BCB nor Berks County Bank has 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 BCB Bank is inappropriate.

each case

other than loans as to which the failure to satisfy the foregoing standards
would not have a Material Adverse Effect on BCB.

       Section 3.20  Accounting for the Consolidation; Reorganization.  As of
                     ------------------------------------------------        
the date hereof, BCB does not have any reason to believe that the Consolidation
will fail to qualify (i) for pooling-of-interests treatment under GAAP, or (ii)
as a reorganization under Section 368(a) of the IRC.

       Section 3.21  Fairness Opinion.  BCB has received an oral opinion from

Janney Montgomery Scott Inc. to the effect that, as of the date hereof, the
exchange ratio to be received by shareholders of BCB pursuant to this Agreement
is fair, from a financial point of view, to such shareholders.

BCB in this Agreement are true, correct and complete in all material respects
and do not omit statements necessary to make the representations not misleading
under the circumstances.

          (a) From the date of this Agreement to the Closing Date, Heritage and
BCB and their respective Subsidiaries will conduct their business and engage in

each of the Subsidiaries to use its reasonable good faith efforts, to (i)

others with whom business relationships exist.  From the date hereof to the

will, or will permit any Subsidiary to:

              (i)  amend or change any provision of its certificate or articles
     of incorporation, charter, or bylaws;

              (ii) change the number of authorized or issued shares of its
     capital stock or issue any shares or issue or grant any option, warrant,

     convertible into shares of such stock, or split, combine or reclassify any
     shares of capital stock, or declare, set

                                      38

     aside or pay any dividend or other distribution in respect of capital
     stock, or redeem or otherwise acquire any shares of capital stock, except
     that (A) Heritage may issue up to an aggregate of 93,052 shares of Heritage
     Common Stock upon the valid exercise of Heritage Options, (B) Heritage may

     Holding Company pay a quarterly dividend of not less than $.14 per quarter.
     Heritage and BCB agree to coordinate (on a mutually agreeable basis) the
     declaration of dividends (and the record of payment dates therefor) payable
     during the period preceding and including the quarter in which the
     Effective Date occurs so that shareholders of Heritage and BCB will receive
     fair dividends and in no event shall shareholders of either Heritage or BCB
     fail to receive a fair dividend during any quarter up to and including the
     quarter immediately following the Effective Date. Nothing contained in this
     Section 4.01(a)(ii) or in any other Section of this Agreement shall be
     construed to permit Heritage or BCB shareholders to receive two dividends
     in any quarter or to deny or prohibit them from receiving one dividend in
     any quarter. Nothing contained herein shall be deemed to affect the ability
     of an Heritage or BCB Subsidiary to pay dividends on its capital stock
     subject to applicable regulatory restrictions.

          (iii)  grant any severance or termination pay (other than pursuant to
     written policies or written

enter into any new or amend any existing employment agreement with, or increase
the compensation of, any employee, officer or director except for routine
periodic increases, that individually and in the aggregate do not exceed 10% and
that are otherwise in accordance with past practice; provided, however, that
nothing herein shall prevent Heritage from establishing a bonus pool in the
aggregate amount of $100,000 to be paid to certain officers and employees solely
for the purpose of inducing such officer or employee to continue working for
Heritage or the Holding Company through a date not more than six (6) months
after the Effective Date.

          (iv)  merge or consolidate any Subsidiary with any other corporation;

otherwise dispose of any of its assets or the assets of any Subsidiary other

(other than in connection with government deposits, repurchase agreements,
bankers acceptances, "treasury tax and loan" accounts established in the
ordinary course of business and transactions in Federal Home Loan Bank advances
and "federal funds" and the satisfaction of legal requirements in the exercise
of trust powers) other than in the ordinary course of business consistent with
past 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 any of its representations
and warranties set forth in this Agreement becoming untrue as of any date after
the date hereof except as otherwise contemplated or permitted by this Agreement,
or in any of the conditions set forth in Article V hereof not being satisfied,
except in each case as may be required by applicable law;

<PAGE>
 
          (vii)   change any method, practice or principle of accounting, except
as may be required from time to time by GAAP (without regard to any optional
early adoption date) or any Regulatory Authority;

          (viii)  waive, release, grant or transfer any rights of value or
modify or change in any material respect any existing material agreement to
which it or any Subsidiary is a party, other than in the ordinary course of
business consistent 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 (except that BCB and Heritage each may adopt its annual
bonus plan in 1998 consistent with past practice), or, except as required by law
and except as set forth in Section 4.10, materially amend any existing plan or
arrangement except to the extent such amendments do not result in an increase in
cost; provided, however, that (A) Heritage may contribute to the Heritage
pension plan an amount not to exceed the minimum amount required under ERISA or
the IRC if such amount is usual and ordinary and consistent with past practice
and (B) Heritage may establish the bonus pool contemplated by 4.01(a)(iii) and
may continue its company-wide bonus program for 1998 on a pro rata basis through
June 30, 1998 for all employees not selected to participate in the Holding
Company bonus plan for 1998 provided that such selected employees shall also
participate unless they participate in the Holding Company bonus plan on a full
year basis.

          (xiv)  except for the execution of this Agreement, take any action
     that would give rise to a right of payment to any individual under any
     employment agreement;

          (xv)   take any action that would preclude the Consolidation from
     qualifying (A) for pooling-of-interests accounting treatment under GAAP or
     (B) as a reorganization within the meaning of Section 368 of the IRC,
     provided, however, that nothing contained herein shall limit the ability of
     either to comply with its obligations under the BCB Option or the Heritage
     Option; or

          (xvi)  agree to do any of the foregoing.

       For purposes of this Section 4.01, it shall not be considered in the
ordinary course of business for either party to do any of the following:  (i)
except for expenditures associated with new branches and the BCB Operations
Center, make any capital expenditure of $100,000 or more not disclosed on the
Heritage or BCB Disclosure Schedule, without the prior written consent of the

other party; (ii) make any sale, assignment, transfer, pledge, hypothecation or

greater, in the aggregate in excess of $250,000, other than pledges of assets to
secure Federal Home Loan Bank advances or government deposits, to exercise trust
powers, sales of assets received in satisfaction of debts previously contracted
in the normal course of business, issuance and sales of loans, or transactions
in the investment securities portfolio or repurchase agreements, in each case,
in the ordinary course of business; or (iii) except for expenditures associated
with new branches and the BCB Operations Center, 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 of more than $250,000 annually, or containing a material financial
commitment and extending beyond 12 months from the date hereof.  Notwithstanding
the foregoing, BCB shall consult with Heritage concerning proposed expenditures

director or officer or employee of either party or any of their respective
Subsidiaries (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 or in part out
of, or pertaining to (i) the fact that he is or was a director, officer or

("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 Heritage, BCB or their
respective Subsidiaries, as the case may be, as of the date hereof including the
right to advancement of expenses, provided, however, that any such officer,
director or employee may not be indemnified by the Holding Company if such
indemnification is prohibited by applicable law.

          (b) Insurance.  The Holding Company shall maintain a directors' and
              ---------                                                      
officers' liability insurance policy providing coverage amounts not less than
the greater of coverage amounts provided under the Heritage or BCB directors and

Such policy shall cover persons who are currently covered by the Heritage and
BCB insurance policies for a period of six years after the Effective Date.

                     ---------------------------------                  
Agreement remains in effect, neither party shall 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

Acquisition Transaction.  Notwithstanding the foregoing, (i) the Board of
Directors of Heritage or BCB may respond to unsolicited inquiries relating to an
Acquisition Transaction or (ii) the Board of Directors of Heritage or BCB 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.  Each party hereto will immediately
cease and cause to be terminated any existing activities, discussions or
negotiations previously conducted with any parties other than the other party
hereto with respect to any of the foregoing, and will take all actions necessary
or advisable to inform the appropriate individuals or entities referred to in
this sentence of the obligations undertaken in this Section 4.06.  Each party
hereto will notify the other party hereto orally (within one day) and in writing
(as promptly as practicable) if any inquiries or proposals relating to an
Acquisition Transaction are received or any such negotiations or discussions are
sought to be initiated or continued.  As used in this Agreement, "Acquisition

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.  Each party shall update its
respective 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

purposes of determining the satisfaction of the condition set forth in Section
5.01(c).

              -----------------                                              
benefits (including miscellaneous benefits) and welfare benefit plans (other
than the welfare plans set forth in subsection 4.10(b) below) of BCB and
Heritage may, at the Holding Company's election and subject to the requirements
of the IRC and any other laws applicable to such benefit plans, continue to be
maintained separately or consolidated. With respect to pension benefit
(retirement) plans and other plans as described below, the following provisions
and guidelines shall apply:

              (i)  Heritage ESOP (Containing 401(k) Provisions).
                   -------------------------------------------- 

                   (A) At some time after the execution of this Agreement but
     prior to the Effective Date, as determined by Heritage, Heritage will take
     action, through its Board of Directors, to terminate the IRC Section 4975
     employee stock ownership plan portion of the Heritage ESOP, effective as of
     the Effective Date. Any action to terminate the IRC Section 4975 portion of
     the Heritage ESOP will be specifically conditioned upon successful
     consummation of the Consolidation. The termination of the Heritage ESOP
     will apply to the IRC Section 4975 employee stock ownership plan portion of
     the Heritage ESOP, and assets related thereto, only. The portion of the
     Heritage ESOP subject to IRC Section 401(k) (salary reduction
     contributions) and IRC Section 401(m) (employer matching contributions),
     and the assets related thereto, shall be handled as set

                                      49
<PAGE>
 
     forth in subparagraph (D) below.  Each participant in the Heritage ESOP not
     fully vested will, in accordance with the termination of the Heritage ESOP,
     become fully vested in all of his or her Heritage ESOP accounts as of the
     date of the effective date of the termination of the Heritage ESOP.
     Heritage shall be responsible for taking all appropriate action, including
     possible amendments to the Heritage ESOP, in order to provide for the
     termination of the IRC Section 4975 employee stock ownership plan portion
     of the Heritage ESOP and the transfer of the IRC Section 401(k) (salary
     reduction) and IRC Section 401(m) (employer matching) portion of the
     Heritage ESOP.  Heritage and BCB agree that, subject to the conditions
     described herein, as soon as practicable after the termination of the IRC
     Section 4975 employee stock ownership plan portion of the Heritage ESOP,
     participants in the Heritage ESOP shall be entitled, at their election, to
     have their Heritage ESOP employer discretionary contribution employee stock
     ownership plan accounts either distributed to them in a lump sum or
     directly transferred to another tax-qualified plan (including the Holding
     Company plan(s)) or to an individual retirement account.  Participants who
     request a direct transfer to the Holding Company's plan(s) will be
     permitted to transfer employer stock and will be permitted to hold employer
     stock in the Holding Company plan(s).

               (B) The actions relating to effectuating termination
     distributions from the Heritage ESOP will be conditioned upon receiving a
     favorable determination letter from the Internal Revenue Service ("IRS")
     with regard to the qualification of the termination of the IRC Section 4975
     employer stock ownership plan portion of the Heritage ESOP.  Heritage and
     the Holding Company will cooperate in submitting appropriate requests for
     any such determination letter to the IRS and will use their best efforts to
     seek the issuance of such letter as soon as practicable following the
     effective date of the termination of the Heritage ESOP.  Heritage and the
     Holding Company will adopt such additional amendments to the Heritage ESOP
     as may be reasonably required by the IRS as a condition to granting such
     determination letter, provided that such amendments do not (i)
     substantially change the terms outlined herein, (ii) have a Material
     Adverse Effect on Heritage or (iii) result in an additional material
     liability to the Holding Company.

               (C) As of and following the Effective Date, the terminated
     Heritage ESOP will not be made available to any employees other than
     persons who were

                                      50
<PAGE>
 
     participants or beneficiaries of the Heritage ESOP as of the effective date
     of the termination.

               (D) As soon as practicable after the consummation of the
     Consolidation, the Holding Company and Heritage will take appropriate
     action to effectuate a plan merger of the IRC Section 401(k) and IRC
     Section 401(m) portions, including the assets related thereto, of the
     Heritage ESOP with and into the BCB 401(k) Plan.  Such plan merger will
     involve the transfer of IRC Section 401(k) contribution assets (and related
     earnings) and IRC Section 401(m) contribution assets (and related earnings)
     in the Heritage ESOP to the BCB 401(k) Plan.

               (E) Heritage will make an employer discretionary contribution to
     the Heritage ESOP for the 1997 Heritage ESOP Plan Year in an amount not to
     exceed $100,000.  After 1997 and up to the termination effective date of
     the IRC Section 4975 employee stock ownership plan portion of the Heritage
     ESOP, Heritage shall make an employer discretionary contribution to the
     Heritage ESOP in an amount not to exceed $8,500 for each complete calendar
     month in 1998 through the Effective Date.  The 1998 employer discretionary
     contribution to the Heritage ESOP is conditioned upon successful
     consummation of the Consolidation.

          (ii) Heritage Pension Plan.  At a date following the execution of
               ---------------------                                       
this Agreement but prior to the Effective Date, as determined by Heritage, the
Heritage Board of Directors shall take the following actions, all subject to
successful consummation of the Consolidation, with respect to the Heritage
Bancorp, Inc.  Employee Retirement Plan ("Heritage Pension Plan"):

               (A) Approve an amendment to the Heritage Pension Plan to provide
     for the freezing of benefit accruals (cessation of future benefit accruals)
     as of the Effective Date.

               (B) Approve an amendment to the Heritage Pension Plan to provide
     for the allocation of excess assets upon plan termination for the benefit
     of active plan participants with accrued benefits under the Heritage
     Pension Plan.

               (C) Approve the termination of the Heritage Pension Plan.

            (b) Retirement Plans Provided to Employees Commencing Upon the
                ----------------------------------------------------------
Effective Date.
- -------------- 

                (i)  BCB 401(k) Plan.  As of the Effective Date, employees of
                     ---------------                                          
     Heritage shall be eligible to participate in the BCB 401(k) Plan.  No later
     than the Effective Date, the BCB 401(k) Plan shall be amended to provide
     for prior Heritage service credit, for eligibility and vesting purposes.
     The BCB 401(k) Plan shall also be amended no later than the Effective Date
     to provide for the participation of eligible Heritage employees in the BCB
     401(k) Plan as of the Effective Date.  A 75% employer matching contribution
     up to 6% of employee IRC Section 401(k) deferrals formula shall be applied
     under the BCB 401(k) Plan for a period of five BCB 401(k) Plan years after
     the Effective Date with the 1998 plan year constituting the first BCB
     401(k) plan year for purposes of the five year period described above.  No
     reduction in the above described formula will be made for the five year
     period described above.  No later than the Effective Date, the BCB 401(k)
     Plan shall also be amended to provide for 100% immediate vesting on all
     employer matching contributions.  On and after the Effective Date the BCB
     401(k) Plan shall continue to make available an employer stock-based
     investment option, and shall consider making available to all participants
     in the BCB 401(k) Plan the participant directed investment options
     currently offered to Heritage employees under the Heritage ESOP. No
     amendment shall be made to the BCB 401(k) Plan regarding full 100% vesting
     on employer matching contributions for the same five year period described
     above.

                (ii) Money Purchase Pension Plan.  As of the Effective Date,
                     ---------------------------                            
     employees of Heritage and BCB shall be eligible to participate in a new
     money purchase pension plan to be established by the Holding Company,
     subject to successful consummation of the

                                      52
<PAGE>
 
     Consolidation.  The money purchase plan shall contain eligibility
     provisions requiring an employee to be at least 21 years of age and have at
     least one year of service, with entry dates of at least January 1 and July
     1; provided, however, the Holding Company may establish eligibility
     provisions which are more liberal than age 21 and one year of service.  The
     money purchase pension plan shall provide for a fixed employer contribution
     equal to 3% of an eligible employee's base salary, shall provide for prior
     Heritage and BCB service credit for eligibility and vesting, shall contain
     a vesting schedule which shall provide 20% vesting for each year of service
     up to 100% vesting upon completion of five years of service and shall
     permit participants to direct the investment of their account balances in
     the money purchase plan in investment options similar to those offered
     under the BCB 401(k) Plan.  In lieu of the adoption of a new money purchase
     plan by the Holding Company, to the extent permitted by the IRC, the
     Holding Company may cause the BCB 401(k) Plan to be amended, as of the
     Effective Date, to provide for a fixed employer contribution in the same
     amount and subject to the same provisions as are set forth in the preceding
     sentence.  The fixed 3% employer contribution formula which shall be
     provided in either a new money purchase plan or in the BCB 401(k) Plan
     shall not be reduced for the same five year period described in
     subparagraph (A) above.

          (iii)  Welfare Benefit Plans.  Following the Consolidation, the
                 ---------------------                                   
Holding Company will adopt the Heritage Blue Cross/Blue Shield Plan, the
Heritage short-term and long-term disability plans and the BCB group life
insurance plan. The Holding Company shall also adopt a Flexible Benefits (IRC
Section 125) Plan similar to the existing Heritage Flexible Benefit Plan.  With
respect to any other welfare benefit plans of BCB and Heritage, the Holding
Company shall undertake a study, in consultation with appropriate professional
advisors, with a view toward the possible combination of some or all of such
plans (other than the welfare plans described above) or the benefits provided
thereunder.  Following such study, the Holding Company shall take such action
with respect to such plans (which may include the implementation of new
benefits, reduction or elimination of some benefits, and/or the alteration of
the respective cost allocation between employer and employee) as it deems
appropriate under the circumstances.

          (iv)   Bonus Plans and Arrangements.  Heritage and BCB may continue to
                 ----------------------------

     of the Consolidation and the timing thereof.

     rights, restricted stock, and performance shares except that BCB may make

                                                                       ---------


                            STOCK OPTION AGREEMENT
                            ----------------------

     THIS STOCK OPTION AGREEMENT ("Stock Option Agreement") dated November 18,
1997, is by and between BCB FINANCIAL SERVICES CORPORATION, a Pennsylvania
corporation ("BCB") and HERITAGE BANCORP, INC., a Pennsylvania corporation
("HERITAGE").

                                  BACKGROUND
                                  ----------

     1.  BCB and Heritage desire to enter into an Agreement and Plan of
Consolidation, dated November 18, 1997 (the "Agreement"), providing, among other
things, for the creation by BCB and Heritage of a bank holding company which
will issue shares of its common stock to the shareholders of BCB and Heritage
(the "Consolidation").

     2.  As a condition to BCB to enter into the Agreement, Heritage is granting
to BCB an option to purchase up to that number of shares of common stock, par
value $5.00 per share (the "Common Stock") of Heritage as shall equal 19.9% of
shares of Common Stock of Heritage issued and outstanding as of the date hereof,
on the terms and conditions hereinafter set forth.

                                   AGREEMENT
                                   ---------

     In consideration of the foregoing and the mutual covenants and agreements
set forth herein, BCB and Heritage, intending to be legally bound hereby, agree:

     1.  Grant of Option. Heritage hereby grants to BCB, on the terms and
         ---------------                                                  
conditions set forth herein, the option to purchase (the "Option") up to 947,041
shares of Common Stock of Heritage (as adjusted as set forth herein, the "Option
Shares") at a price per share (as adjusted as set forth herein, the "Option
Price") equal to $22.875, provided, however, that in no event shall the number
of Option Shares for which the Option is exercisable exceed 19.9% of the issued
and outstanding shares of Heritage Common Stock without giving effect to any
shares subject to or issued pursuant to the Option.

     2.  Exercise of Option.
         ------------------ 

         (a) Provided that (i) BCB shall not be, on the date of exercise, in
material breach of the agreements or covenants contained in the Agreement, this
Stock Option Agreement or the reciprocal Stock Option Agreement by and between
Heritage and BCB, and (ii) no preliminary or permanent injunction or other order
against the delivery of shares covered by the Option issued by any court of
competent jurisdiction in the United States shall be in effect on the date of
exercise, upon or after the occurrence of a Triggering Event (as such term is
hereinafter

                                       1
<PAGE>
 
defined) BCB may exercise the Option, in whole or in part, at any time or one or
more times, from time to time; provided that the Option shall terminate and be
of no further force and effect upon the earliest to occur of (A) the Effective
Date of the Consolidation, as provided in the Agreement, (B) termination of the
Agreement in accordance with the terms thereof prior to the occurrence of a
Triggering Event or a Preliminary Triggering Event, other than a termination of
the Agreement pursuant to Section 6.01(d), unless in the case of termination by
Heritage pursuant to Section 6.01(d), such termination is as a result of a
willful breach of the Agreement by BCB (a termination pursuant to Section
6.01(d), except a termination by Heritage as a result of a willful breach by
BCB, being referred to herein as a "Default Termination"), (C) 18 months after
the termination of the Agreement by BCB or Heritage pursuant to a Default
Termination, and (D) 18 months after termination of the Agreement (other than
pursuant to a Default Termination) following the occurrence of a Triggering
Event or a Preliminary Triggering Event; and provided, further, that any
purchase of shares upon exercise of the Option shall be subject to compliance
with applicable securities and banking laws. The rights set forth in Section 3
hereof shall terminate when the right to exercise the Option terminates (other
than as a result of a complete exercise of the Option) as set forth above.

         (b) As used herein, the term "Triggering Event" means the occurrence of
any of the following events:

             (i)  a person or group (as such terms are defined in the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
     rules and regulations thereunder), other than BCB or an affiliate of BCB,
     acquires beneficial ownership (within the meaning of Rule 13d-3 under the
     Exchange Act) of 25% or more of the then outstanding shares of Common Stock
     (excluding any shares eligible to be reported on Schedule 13G of the
     Securities and Exchange Commission); or

             (ii) a person or group, other than BCB or an affiliate of BCB,
     enters into an agreement or letter of intent or memorandum of understanding
     with Heritage or Heritage shall have authorized, recommended or publicly
     proposed, or publicly announced an intention to authorize, recommend or
     propose, such an agreement or letter of intent or memorandum of
     understanding, pursuant to which such person or group or any affiliate of
     such person or group would (i) merge or consolidate, or enter into any
     similar transaction, with Heritage, (ii) acquire all or substantially all
     of the assets or liabilities of Heritage or all or substantially all of the
     assets or liabilities of Heritage National Bank (or any successor
     subsidiary), the wholly-owned subsidiary of Heritage ("Heritage Bank"), or
     (iii) acquire beneficial ownership of securities representing, or the right
     to acquire beneficial ownership

                                       2
<PAGE>
 
     or to vote securities representing, 25% or more of the then outstanding
     shares of Common Stock (excluding any shares eligible to be reported on
     Schedule 13G of the Securities and Exchange Commission) or the then
     outstanding shares of common stock of Heritage Bank.

         (c) As used herein, the term "Preliminary Triggering Event" means the
occurrence of any of the following events:

             (i)   a person or group (as such terms are defined in the Exchange
     Act and the rules and regulations thereunder), other than BCB or an
     affiliate of BCB, 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 Securities and Exchange Commission);

             (ii)  a person or group, other than BCB or an affiliate of BCB,
     publicly announces a bona fide proposal (including a written communication
     that is or becomes the subject of public disclosure) for (i) any merger,
     consolidation or acquisition of all or substantially all the assets or
     liabilities of Heritage or all or substantially all the assets or
     liabilities of Heritage Bank, or any other business combination involving
     Heritage or Heritage Bank, or (ii) 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 Heritage Bank (collectively, a "Proposal"), and thereafter,
     if such Proposal has not been Publicly Withdrawn (as such term is
     hereinafter defined) at least 30 days prior to the meeting of shareholders
     of Heritage called to vote on the Consolidation, Heritage's shareholders
     fail to approve the Consolidation by the vote required by applicable law at
     the meeting of shareholders called for such purpose or such meeting has
     been cancelled; or

             (iii) the Board of Directors of Heritage shall (A) exercise the
     right granted to it in clause (i) of the second sentence of Section 4.06 of
     the Agreement, (B) fail to recommend the Consolidation, (C) recommend an
     Acquisition Transaction or (D) have withdrawn or modified in a manner
     adverse to BCB the recommendation of the Board of Directors of Heritage
     with respect to the Agreement and thereafter Heritage's shareholders fail
     to approve the Consolidation by the vote required by law at the meeting of
     shareholders called for such purpose or such meeting is not scheduled or is
     cancelled without the written consent of BCB; or

                                       3
<PAGE>
 
             (iv)  a person or group, other than BCB or an affiliate of BCB,
     makes a bona fide Proposal and thereafter, but before such Proposal has
     been Publicly Withdrawn, Heritage shall have breached any representation,
     warranty, covenant or obligation contained in the Agreement and such breach
     would entitle BCB to terminate the Agreement under Section 6.01(d) thereof
     (without regard to the cure period provided for therein unless such cure is
     promptly effected without jeopardizing consummation of the Consolidation
     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.

     "Publicly Withdrawn" for purposes of this Section 2 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 Heritage or in soliciting or inducing any other
person (other than BCB or an affiliate of BCB) to do so.

     Notwithstanding the foregoing, the obligation of Heritage 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 Heritage to issue the Option Shares or BCB 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 provision to the contrary set forth herein, the Option
shall not expire or otherwise terminate with respect to the Option Shares
subject to any prior exercise.

     Heritage shall notify BCB promptly in writing of the occurrence of any
Triggering Event known to it, it being understood that the giving of such notice
by Heritage shall not be a condition to the right of BCB to exercise the Option.
Heritage will not take any action which would have the effect of preventing or
disabling Heritage from delivering the Option Shares to BCB 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 BCB wishes to exercise the Option, BCB shall
send a written notice to Heritage (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 between two and ten business days inclusive from
the

                                       4
<PAGE>
 
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 Heritage.
         -------------------------------- 
 
         (a) Subject to the last sentence of Section 2(a), at the request of BCB
at any time commencing upon the first occurrence of a Repurchase Event (as
defined in Section 3(d)) and ending 18 months immediately thereafter, Heritage
shall repurchase from BCB (x) the Option and (y) all shares of Common Stock
purchased by BCB pursuant hereto with respect to which BCB then has beneficial
ownership. The date on which BCB 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 Purchase Price paid by BCB for any shares of
     Common Stock acquired pursuant to the Option with respect to which BCB then
     has beneficial ownership;

             (ii)  the excess, if any, of (x) the Applicable Price (as defined
     below) for each share of Common Stock over (y) 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 BCB for each share of Common
     Stock with respect to which the Option has been exercised and with respect
     to which BCB then has beneficial ownership, multiplied by the number of
     such shares.
 
         (b) If BCB exercises it rights under this Section 3, Heritage shall,
within ten (10) business days after the Request Date, pay the Section 3
Repurchase Consideration to BCB in immediately available funds, and
contemporaneously with such payment, BCB shall surrender to Heritage the Option
and the certificate evidencing the shares of Common Stock purchased thereunder
with respect to which BCB then has beneficial ownership, and BCB 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. Notwithstanding the foregoing, 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 FRB, the OCC, the FDIC, or
the

                                       5
<PAGE>
 
respective staffs thereof (the "Regulatory Authority"), is required in
connection with the payment of all or any portion of the Section 3 Repurchase
Consideration, BCB shall have the ongoing option to revoke its request for
repurchase pursuant to Section 3, in whole or in part, or to require that
Heritage 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 (and each party shall cooperate with the other in the filing of any such
notice or application and the obtaining of any such approval), in which case the
ten (10) business day period of time that would otherwise run pursuant to the
preceding sentence 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. If any Regulatory Authority disapproves of any part of Heritage's
proposed repurchase pursuant to this Section 3, Heritage shall promptly give
notice of such fact to BCB. If any Regulatory Authority prohibits the repurchase
pursuant to this Section 3, Heritage shall promptly give notice of such fact to
BCB. If any Regulatory Authority prohibits the repurchase in part but not in
whole, then BCB shall have the right (i) to revoke the repurchase request or
(ii) to the extent permitted by such Regulatory Authority, determine whether the
repurchase should apply to the Option and/or Option Shares and to what extent to
each, and BCB 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. BCB
shall notify Heritage 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 groups described in 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 Nasdaq Stock Market during the 40 business days
preceding the Request Date; provided, however, that in the event of a sale of
less than all of Heritage'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 Heritage as determined by a nationally-recognized investment
banking firm selected by BCB, divided by the number of shares of Common Stock
outstanding at the time of such sale. If the consideration to be

                                       6
<PAGE>
 
offered, paid or received pursuant to either of the foregoing 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 BCB and reasonably acceptable to Heritage, 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 such terms are defined in the Exchange Act and the rules and
regulations thereunder), other than BCB or an affiliate of BCB, 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) Heritage shall have merged or
consolidated with any person, other than BCB or an affiliate of BCB, and shall
not be the surviving or continuing corporation of such merger or consolidation,
(iii) any person, other than BCB or an affiliate of BCB, shall have merged into
Heritage and Heritage 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 Heritage 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
(iv) Heritage shall have sold or otherwise transferred more than 25% of its
consolidated assets to any person, other than BCB or an affiliate of BCB.

     4.  Payment and Delivery of Certificates. At any Closing hereunder,
         ------------------------------------                            
(a) BCB will make payment to Heritage of the aggregate price for the Option
Shares so purchased by wire transfer of immediately available funds to an
account designated by Heritage, (b) Heritage will deliver to BCB a stock
certificate or certificates representing the number of Option Shares so
purchased, registered in the name of BCB or its designee, in such denominations
as were specified by BCB in its notice of exercise, and (c) BCB 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 Heritage Bancorp, Inc. receives an
     opinion of counsel acceptable to it stating that an

                                       7
<PAGE>
 
     exemption from the registration provisions of the Act is available for such
     transfer."

     5.  Registration Rights. Upon or after the occurrence of a Triggering 
         -------------------                                    
Event and upon receipt of a written request from BCB, Heritage shall prepare and
file as soon as practicable a registration statement under the Securities Act of
1933 (the "Securities Act") with the Securities and Exchange Commission covering
the Option and such number of Option Shares as BCB shall specify in its request,
and Heritage 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 and the Option Shares, provided that BCB shall in no event have the right
to have more than one such registration statement become effective, and provided
further that Heritage shall not be required to prepare and file any such
registration statement in connection with any proposed sale with respect to
which counsel to Heritage delivers to Heritage and to BCB its opinion to the
effect that no such filing is required under applicable laws and regulations
with respect to such sale or disposition; provided further, however, that
Heritage may delay any registration of Option Shares above for a period not
exceeding 90 days in the event that Heritage shall in good faith determine that
any such registration would adversely affect an offering or contemplated
offering of securities by Heritage. BCB shall provide all information reasonably
requested by Heritage for inclusion in any registration statement to be filed
hereunder. In connection with such filing, Heritage shall use its reasonable
best efforts to cause to be delivered to BCB such certificates, opinions,
accountant's letters and other documents as BCB shall reasonably request and as
are customarily provided in connection with registration of securities under the
Securities Act. Heritage shall provide to BCB such number of copies of the
preliminary prospectus and final prospectus and any amendments and supplements
thereto as BCB may reasonably request.

     All reasonable expenses incurred by Heritage 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 Heritage and blue sky fees and expenses, shall be paid by
Heritage. Underwriting discounts and commissions to brokers and dealers relating
to the Option Shares, fees and disbursements of counsel to BCB and any other
expenses incurred by BCB in connection with such filing shall be borne by BCB.
In connection with such filing, Heritage shall indemnify and hold harmless BCB
against any losses, claims, damages or liabilities, joint or several, to which
BCB 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

required to be stated therein or necessary to make the statements therein not
misleading; and Heritage will reimburse BCB for any legal or other expense
reasonably incurred by BCB in connection with investigating or defending any

     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

matter hereof.

transfer its rights and obligations hereunder, in whole or in part, to any
person or group of persons other than to a subsidiary of BCB. BCB represents
that it is acquiring the Option for BCB's own account and not with a view to, or

Shares. BCB is aware that neither the Option nor the Option Shares is the
subject of a registration statement filed with, and declared effective by, the
Securities and Exchange Commission pursuant to Section 5 of the Securities Act,

                            STOCK OPTION AGREEMENT
                            ----------------------

          THIS STOCK OPTION AGREEMENT ("Stock Option Agreement") dated November
18, 1997, is by and between HERITAGE BANCORP, INC., a Pennsylvania corporation
("Heritage") and BCB FINANCIAL SERVICES CORPORATION, a Pennsylvania corporation
("BCB").

                                  BACKGROUND
                                  ----------

          1.  Heritage and BCB desire to enter into an Agreement and Plan of
Consolidation, dated November 18, 1997 (the "Agreement"), providing, among other
things, for the creation by Heritage and BCB of a bank holding company which
will issue shares of its common stock to the shareholders of Heritage and BCB
(the "Consolidation").

          2.  As a condition to Heritage to enter into the Agreement, BCB is
granting to Heritage an option to purchase up to that number of shares of common
stock, par value $2.50 per share (the "Common Stock") of BCB as shall equal
19.9% of shares of Common Stock of BCB issued and outstanding as of the date
hereof, on the terms and conditions hereinafter set forth.

                                   AGREEMENT
                                   ---------

          In consideration of the foregoing and the mutual covenants and
agreements set forth herein, Heritage and BCB, intending to be legally bound
hereby, agree:

          1.  Grant of Option. BCB hereby grants to Heritage, on the terms and
              ---------------                                                  
conditions set forth herein, the option to purchase (the "Option") up to 690,516
shares of Common Stock of BCB (as adjusted as set forth herein, the "Option
Shares") at a price per share (as adjusted as set forth herein, the "Option
Price") equal to $22.375, provided, however, that in no event shall the number
of Option Shares for which the Option is exercisable exceed 19.9% of the issued
and outstanding shares of BCB Common Stock without giving effect to any shares
subject to or issued pursuant to the Option.

          2.  Exercise of Option.
              ------------------ 

              (a) Provided that (i) Heritage shall not be, on the date of
exercise, in material breach of the agreements or covenants contained in the
Agreement, this Stock Option Agreement or the reciprocal Stock Option Agreement
by and between BCB and Heritage, and (ii) no preliminary or permanent injunction
or other order against the delivery of shares covered by the Option issued by
any court of competent jurisdiction in the United States shall be in effect on
the date of exercise, upon or after the occurrence of a Triggering Event (as
such term is hereinafter

                                       1
<PAGE>
 
defined) Heritage may exercise the Option, in whole or in part, at any time or
one or more times, from time to time; provided that the Option shall terminate
and be of no further force and effect upon the earliest to occur of (A) the
Effective Date of the Consolidation, as provided in the Agreement, (B)
termination of the Agreement in accordance with the terms thereof prior to the
occurrence of a Triggering Event or a Preliminary Triggering Event, other than a
termination of the Agreement pursuant to Section 6.01(d), unless in the case of
termination by BCB pursuant to Section 6.01(d), such termination is as a result
of a willful breach of the Agreement by Heritage (a termination pursuant to
Section 6.01(d), except a termination by BCB as a result of a willful breach by
Heritage, being referred to herein as a "Default Termination"), (C) 18 months
after the termination of the Agreement by Heritage or BCB pursuant to a Default
Termination, and (D) 18 months after termination of the Agreement (other than
pursuant to a Default Termination) following the occurrence of a Triggering
Event or a Preliminary Triggering Event; and provided, further, that any
purchase of shares upon exercise of the Option shall be subject to compliance
with applicable securities and banking laws.  The rights set forth in Section 3
hereof shall terminate when the right to exercise the Option terminates (other
than as a result of a complete exercise of the Option) as set forth above.

              (b) As used herein, the term "Triggering Event" means the
occurrence of any of the following events:

                  (i)  a person or group (as such terms are defined in the 
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
     rules and regulations thereunder), other than Heritage or an affiliate of
     Heritage, acquires beneficial ownership (within the meaning of Rule 13d-3
     under the Exchange Act) of 25% or more of the then outstanding shares of
     Common Stock (excluding any shares eligible to be reported on Schedule 13G
     of the Securities and Exchange Commission); or

                  (ii) a person or group, other than Heritage or an affiliate of
     Heritage, enters into an agreement or letter of intent or memorandum of
     understanding with BCB or BCB shall have authorized, recommended or
     publicly proposed, or publicly announced an intention to authorize,
     recommend or propose, such an agreement or letter of intent or memorandum
     of understanding, pursuant to which such person or group or any affiliate
     of such person or group would (i) merge or consolidate, or enter into any
     similar transaction, with BCB, (ii) acquire all or substantially all of the
     assets or liabilities of BCB or all or substantially all of the assets or
     liabilities of Berks County Bank (or any successor subsidiary), the wholly-
     owned subsidiary of BCB ("BCB Bank"), or (iii) acquire beneficial ownership
     of securities representing, or the right to acquire beneficial ownership or
     to vote securities representing, 25% or more of

                                       2
<PAGE>
 
     the then outstanding shares of Common Stock (excluding any shares eligible
     to be reported on Schedule 13G of the Securities and Exchange Commission)
     or the then outstanding shares of common stock of BCB Bank.

              (c) As used herein, the term "Preliminary Triggering Event" means
the occurrence of any of the following events:

                  (i)   a person or group (as such terms are defined in the 
     Exchange Act and the rules and regulations thereunder), other than Heritage
     or an affiliate of Heritage, 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 Securities and Exchange Commission);

                  (ii)  a person or group, other than Heritage or an affiliate 
     of Heritage, publicly announces a bona fide proposal (including a written
     communication that is or becomes the subject of public disclosure) for (i)
     any merger, consolidation or acquisition of all or substantially all the
     assets or liabilities of BCB or all or substantially all the assets or
     liabilities of BCB Bank, or any other business combination involving BCB or
     BCB Bank, or (ii) 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 BCB Bank (collectively, a "Proposal"), and thereafter, if such
     Proposal has not been Publicly Withdrawn (as such term is hereinafter
     defined) at least 30 days prior to the meeting of shareholders of BCB
     called to vote on the Consolidation, BCB's shareholders fail to approve the
     Consolidation by the vote required by applicable law at the meeting of
     shareholders called for such purpose or such meeting has been cancelled; or

                  (iii) the Board of Directors of BCB shall (A) exercise the 
     right granted to it in clause (i) of the second sentence of Section 4.06 of
     the Agreement, (B) fail to recommend the Consolidation, (C) recommend an
     Acquisition Transaction or (D) have withdrawn or modified in a manner
     adverse to Heritage the recommendation of the Board of Directors of BCB
     with respect to the Agreement and thereafter BCB's shareholders fail to
     approve the Consolidation by the vote required by law at the meeting of
     shareholders called for such purpose or such meeting is not scheduled or is
     cancelled without the written consent of Heritage; or

                                       3
<PAGE>
 
                  (iv) a person or group, other than Heritage or an affiliate of
     Heritage, makes a bona fide Proposal and thereafter, but before such
     Proposal has been Publicly Withdrawn, BCB shall have breached any
     representation, warranty, covenant or obligation contained in the Agreement
     and such breach would entitle Heritage to terminate the Agreement under
     Section 6.01(d) thereof (without regard to the cure period provided for
     therein unless such cure is promptly effected without jeopardizing
     consummation of the Consolidation 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.

          "Publicly Withdrawn" for purposes of this Section 2 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 BCB or in soliciting or inducing any other person
(other than Heritage or an affiliate of Heritage) to do so.

          Notwithstanding the foregoing, the obligation of BCB 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 BCB to issue the Option Shares or Heritage 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 provision to the contrary set forth herein, the Option
shall not expire or otherwise terminate with respect to the Option Shares
subject to any prior exercise.

          BCB shall notify Heritage promptly in writing of the occurrence of any
Triggering Event known to it, it being understood that the giving of such notice
by BCB shall not be a condition to the right of Heritage to exercise the Option.
BCB will not take any action which would have the effect of preventing or
disabling BCB from delivering the Option Shares to Heritage 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 Heritage wishes to exercise the Option,
Heritage shall send a written notice to BCB (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 between two and ten business days
inclusive from

                                       4
<PAGE>
 
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 BCB.
              --------------------------- 
 
              (a) Subject to the last sentence of Section 2(a), at the request
of Heritage at any time commencing upon the first occurrence of a Repurchase
Event (as defined in Section 3(d)) and ending 18 months immediately thereafter,
BCB shall repurchase from Heritage (x) the Option and (y) all shares of Common
Stock purchased by Heritage pursuant hereto with respect to which Heritage then
has beneficial ownership. The date on which Heritage 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 Purchase Price paid by Heritage for any 
     shares of Common Stock acquired pursuant to the Option with respect to
     which Heritage then has beneficial ownership;

                  (ii)  the excess, if any, of (x) the Applicable Price (as 
     defined below) for each share of Common Stock over (y) 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 Heritage for each share of
     Common Stock with respect to which the Option has been exercised and with
     respect to which Heritage then has beneficial ownership, multiplied by the
     number of such shares.
 
              (b) If Heritage exercises it rights under this Section 3, BCB
shall, within ten (10) business days after the Request Date, pay the Section 3
Repurchase Consideration to Heritage in immediately available funds, and
contemporaneously with such payment, Heritage shall surrender to BCB the Option
and the certificate evidencing the shares of Common Stock purchased thereunder
with respect to which Heritage then has beneficial ownership, and Heritage 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. Notwithstanding the foregoing, to the
extent that prior notification to or approval of any banking

                                       5
<PAGE>
 
agency or department of any federal or state government, including without
limitation the FRB, the OCC, the FDIC, 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, Heritage shall have the
ongoing option to revoke its request for repurchase pursuant to Section 3, in
whole or in part, or to require that BCB 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 (and each party shall cooperate with the other in
the filing of any such notice or application and the obtaining of any such
approval), in which case the ten (10) business day period of time that would
otherwise run pursuant to the preceding sentence 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. If any Regulatory Authority
disapproves of any part of BCB's proposed repurchase pursuant to this Section 3,
BCB shall promptly give notice of such fact to Heritage. If any Regulatory
Authority prohibits the repurchase pursuant to this Section 3, BCB shall
promptly give notice of such fact to Heritage. If any Regulatory Authority
prohibits the repurchase in part but not in whole, then Heritage shall have the
right (i) to revoke the repurchase request or (ii) to the extent permitted by
such Regulatory Authority, determine whether the repurchase should apply to the
Option and/or Option Shares and to what extent to each, and Heritage 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. Heritage shall notify
BCB 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 groups described in 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 Nasdaq Stock Market during the 40 business days
preceding the Request Date; provided, however, that in the event of a sale of
less than all of BCB'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 BCB as determined by a nationally-recognized investment
banking firm selected by Heritage, divided by the number of shares of Common
Stock

                                       6
<PAGE>
 
outstanding at the time of such sale. If the consideration to be offered, paid
or received pursuant to either of the foregoing 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 Heritage and reasonably acceptable to BCB, 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 such terms are defined in the Exchange Act and the rules and
regulations thereunder), other than Heritage or an affiliate of Heritage,
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) BCB shall have merged or
consolidated with any person, other than Heritage or an affiliate of Heritage,
and shall not be the surviving or continuing corporation of such merger or
consolidation, (iii) any person, other than Heritage or an affiliate of
Heritage, shall have merged into BCB and BCB 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 BCB 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 (iv) BCB shall have sold or otherwise transferred more than 25%
of its consolidated assets to any person, other than Heritage or an affiliate of
Heritage.

          4.  Payment and Delivery of Certificates. At any Closing hereunder,
              ------------------------------------                            
(a) Heritage will make payment to BCB of the aggregate price for the Option
Shares so purchased by wire transfer of immediately available funds to an
account designated by BCB, (b) BCB will deliver to Heritage a stock certificate
or certificates representing the number of Option Shares so purchased,
registered in the name of Heritage or its designee, in such denominations as
were specified by Heritage in its notice of exercise, and (c) Heritage 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

                                       7
<PAGE>
 
     to such time unless BCB Financial Services Corporation 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. Upon or after the occurrence of a Triggering
              -------------------                                    
Event and upon receipt of a written request from Heritage, BCB shall prepare and
file as soon as practicable a registration statement under the Securities Act of
1933 (the "Securities Act") with the Securities and Exchange Commission covering
the Option and such number of Option Shares as Heritage shall specify in its
request, and BCB 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 and the Option Shares, provided that Heritage shall in no event have the
right to have more than one such registration statement become effective, and
provided further that BCB shall not be required to prepare and file any such
registration statement in connection with any proposed sale with respect to
which counsel to BCB delivers to BCB and to Heritage its opinion to the effect
that no such filing is required under applicable laws and regulations with
respect to such sale or disposition; provided further, however, that BCB may
delay any registration of Option Shares above for a period not exceeding 90 days
in the event that BCB shall in good faith determine that any such registration
would adversely affect an offering or contemplated offering of securities by
BCB. Heritage shall provide all information reasonably requested by BCB for
inclusion in any registration statement to be filed hereunder. In connection
with such filing, BCB shall use its reasonable best efforts to cause to be
delivered to Heritage such certificates, opinions, accountant's letters and
other documents as Heritage shall reasonably request and as are customarily
provided in connection with registration of securities under the Securities Act.
BCB shall provide to Heritage such number of copies of the preliminary
prospectus and final prospectus and any amendments and supplements thereto as
Heritage may reasonably request.

          All reasonable expenses incurred by BCB 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 BCB and blue sky fees and expenses, shall be paid by BCB.
Underwriting discounts and commissions to brokers and dealers relating to the
Option Shares, fees and disbursements of counsel to Heritage and any other
expenses incurred by Heritage in connection with such filing shall be borne by
Heritage. In connection with such filing, BCB shall indemnify and hold harmless
Heritage against any losses, claims, damages or liabilities, joint or several,
to which Heritage 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

                                       8
<PAGE>
 
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
BCB will reimburse Heritage for any legal or other expense reasonably incurred
by Heritage in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that BCB 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 behalf of Heritage specifically for use
in the preparation thereof. Heritage will indemnify and hold harmless BCB 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 Heritage for use
in the preparation of such preliminary or final registration statement or such
amendment or supplement thereto; and Heritage will reimburse BCB for any legal
or other expense reasonably incurred by BCB in connection with investigating or
defending any such loss, claim, damage, liability or action. Notwithstanding
anything to the contrary contained herein, 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 Heritage and BCB 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, Heritage shall file a report of beneficial ownership on Form
13D with the Securities and Exchange Commission under the Exchange Act which
discloses the rights of Heritage hereunder.

          8.  Representations and Warranties of BCB. BCB hereby represents and
              -------------------------------------                            
warrants to Heritage as follows:

              (a) Due Authorization. BCB 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 BCB. This Stock Option Agreement constitutes a
legal, valid and binding obligation of BCB, enforceable against BCB in
accordance with its terms (except as may be limited by applicable bankruptcy,
insolvency,

                                       9
<PAGE>
 
reorganization, moratorium, fraudulent transfer and similar laws of general
applicability relating to or affecting creditors' rights or by general equity
principles).

              (b) Authorized Shares. BCB 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.

          9.  Representations and Warranties of Heritage. Heritage hereby
              ------------------------------------------                  
represents and warrants to BCB that Heritage 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 Heritage.  This Stock Option  Agreement
constitutes a legal, valid and binding obligation of Heritage, enforceable
against Heritage in accordance with its terms (except as may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and similar laws of general applicability relating to or affecting
creditors' rights or by general equity principles).

          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. Heritage 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 a subsidiary of Heritage. Heritage
represents that it is acquiring the Option for Heritage's own account and not
with a view to, or for sale in connection with, any distribution of the Option
or the Option Shares. Heritage is aware that neither the Option nor the Option
Shares is the subject of a registration statement filed with, and declared
effective by, the Securities and Exchange Commission 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) thereof and
the representations and warranties made by Heritage 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

                                      10
<PAGE>
 
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
              --------

any other provisions of this Stock Option Agreement, which shall remain in full
force and effect.

          15. Notices. All notices, requests, consents and other communications
              -------

                            ______________________


     FIRST.  The name of the Corporation is ____________________.

     SECOND.  The location and post office address of the Corporation's
registered office in this Commonwealth is 400 Washington Street, Reading,
Pennsylvania 19603.

     THIRD.  The purpose of the Corporation is and it shall have unlimited power
to engage in and to do any lawful act concerning any or all lawful business for
which corporations may be incorporated under provisions of the Business
Corporation Law of 1988, the Act approved December, 1988, P.L. 1444, as amended
(the "Pennsylvania Business Corporation Law").

     FOURTH.  The term of the Corporation's existence is perpetual.

     FIFTH.  The aggregate number of shares of capital stock which the
Corporation shall have authority to issue is 55,000,000 shares, divided into two
classes consisting of 50,000,000 shares of common stock, par value $1.00 per
share (the "Common Stock") and 5,000,000 shares of preferred stock, having such
par value as the board of directors shall fix and determine, as provided in
Article SIXTH below (the "Preferred Stock").

     SIXTH.  The Preferred Stock may be issued from time to time as a class
without series or, if so determined by the board of directors of the
Corporation, either in whole or in part, in one or more series.  There is hereby
expressly granted to and vested in the board of directors of the Corporation
authority to fix and determine (except as fixed and determined herein), by
resolution, the par value, voting powers, full or limited, or no voting powers,
and such designations, preferences and relative, participating, optional or
other special rights, if any, and the qualifications, limitations or
restrictions thereof, if any, including specifically, but not limited to, the
dividend rights, conversion rights, redemption rights and liquidation
preferences, if any, of any wholly unissued series of Preferred Stock (or the
entire class of Preferred Stock if none of such shares have been issued), the
number of shares constituting any such series and the terms and conditions of
the issue thereof.  Prior to the issuance of any shares of Preferred Stock, a
statement setting forth a copy of each such resolution or resolutions and the
number of shares of Preferred Stock of each such class or series shall be
executed and filed in accordance with the Pennsylvania Business Corporation Law.
Unless otherwise provided in any such resolution or resolutions, the number of
shares of capital stock of any such class or series so set forth in such
resolution or resolutions may thereafter be increased or decreased (but not
below the number of shares then outstanding), by a statement

                                       1
<PAGE>
 
likewise executed and filed setting forth a statement that a specified increase
or decrease therein had been authorized and directed by a resolution or
resolutions likewise adopted by the board of directors of the Corporation.  In
case the number of such shares shall be decreased, the number of shares so
specified in the statement shall resume the status they had prior to the
adoption of the first resolution or resolutions.

     SEVENTH.  Each holder of record of Common Stock shall have the right to one
vote for each share of Common Stock standing in such holder's name on the books
of the Corporation.  No shareholder shall be entitled to cumulate any votes for
the election of directors.

     EIGHTH.  For a period of three (3) years after the formation of the
Corporation, the Board of Directors shall consist of at least thirteen (13)
directors, (i) seven (7) of whom shall have been directors of BCB Financial
Services Corporation or chosen by directors of the Holding Company who were
directors of BCB Financial Services Corporation, and (ii) six (6) of whom shall
have been directors of Heritage Bancorp, Inc. or chosen by directors of the
Holding Company who were directors of Heritage Bancorp, Inc.  Thereafter, the
management, control and government of the Corporation shall be vested in a board
of directors consisting of not less than five (5) nor more than twenty-five (25)
members in number, as fixed by the board of directors of the Corporation from
time to time.  The directors of the Corporation shall be divided into three
classes:  Class I, Class II and Class III.  Each Class shall be as nearly equal
in number as possible.  If the number of Class I, Class II or Class III
directors is fixed for any term of office, it shall not be increased during that
term, except by a majority vote of the board of directors.  The term of office
of the initial Class I directors shall expire at the annual election of
directors by the shareholders of the Corporation in 1998; the term of office of
the initial Class II directors shall expire at the annual election of directors
by the shareholders of the Corporation in 1999; and the term of office of the
initial Class III directors shall expire at the annual election of directors by
the shareholders of the Corporation in 2000.  After the initial term of each
Class, the term of office of each Class shall be three (3) years, so that the
term of office of one class of directors shall expire each year when their
respective successors have been duly elected by the shareholders and qualified.
At each annual election by the shareholders of the Corporation, the directors
chosen to succeed those whose terms then expire shall be identified as being of
the same class as the directors they succeed.  Unless waived by the board of
directors of the Corporation, in order to qualify for election as a director of
the Corporation, a person must have been a shareholder of record of the
Corporation for a period of time equal to the lesser of (i) three (3) years, or
(ii) the time elapsed since the consolidation of BCB Financial Services
Corporation and Heritage Bancorp, Inc. into the Corporation (the
"Consolidation").

                                       2
<PAGE>
 
Shareholders of another corporation that merges with the Corporation, is
acquired by, or acquires the Corporation, or enters into any similar transaction
with the Corporation shall qualify for election as a director of the Corporation
if such shareholder was a shareholder of record of the other corporation for a
period of time equal to the lesser of (i) three (3) years, or (ii) the time
elapsed since the Consolidation.  If, for any reason, a vacancy occurs on the
board of directors of the Corporation, a majority of the remaining directors
shall have the exclusive power to fill the vacancy by electing a director to
hold office for the unexpired term in respect of which the vacancy occurred.  No
director of the Corporation shall be removed from office, as a director, by the
vote of shareholders, unless the votes of shareholders cast in favor of the
resolution for the removal of such director constitute at least a majority of
the votes which all shareholders would be entitled to cast at an annual election
of directors.

     NINTH.  No holder of any class of capital stock of the Corporation shall
have preemptive rights, and the Corporation shall have the right to issue and to
sell to any person or persons any shares of its capital stock or any option,
warrant or right to acquire capital stock, or any securities having conversion
or option rights without first offering such shares, rights or securities to any
holder of any class of capital stock of the Corporation.

     TENTH.  Except as set forth below, the affirmative vote of at least 80
percent (80%) of votes cast by shareholders entitled to vote, and if any class
of shares is entitled to vote as a separate class, the affirmative vote of
shareholders entitled to cast at least a majority of the votes cast by the
outstanding shares of such class (or such greater amount as required by the
provisions of these Articles of Incorporation establishing such class) shall be
required to approve any of the following:

          (a) any merger or consolidation of the Corporation with or into any
     other corporation;

          (b) any share exchange in which a corporation, person or entity
     acquires the issued or outstanding shares of capital stock of the
     Corporation pursuant to a vote of shareholders;

          (c) any sale, lease, exchange or other transfer of all, or
     substantially all, of the assets of the Corporation to any other
     corporation, person or entity; or

          (d) any transaction similar to, or having similar effect as, any of
     the foregoing transactions.

     The board of directors of the Corporation shall have the power and duty to
determine, for purposes of this Article TENTH, on the basis of information known
to the board, if any

                                       3
<PAGE>
 
transaction is similar to, or has an effect similar to, any of the transactions
identified above in this Article TENTH.  Any such determination shall be
conclusive and binding for all purposes of this Article TENTH.  The Corporation
may voluntarily completely liquidate and/or dissolve only in accordance with all
applicable laws and only if the proposed liquidation and/or dissolution is
approved by the affirmative vote of shareholders entitled to cast at least 80
percent (80%) of the votes which all shareholders are entitled to cast.  The
provisions of this Article TENTH shall not apply to any transaction which is
approved in advance by 75 percent (75%) of the members of the board of directors
of the Corporation, at a meeting duly called and held.

     ELEVENTH.  Subsection 1.  No Person or Group Acting in Concert shall
Acquire Voting Control of the Corporation, at any time, except in accordance
with the provisions of Article TENTH.  The terms "Acquire," "Voting Control,"
"Group Acting in Concert," and "Person" as used in this Article ELEVENTH are
defined in subsection 4 hereof.

          Subsection 2.  If Voting Control of the Corporation is acquired, in
violation of this Article ELEVENTH, all shares with respect to which any Person
or Group Acting in Concert has acquired Voting Control in excess of the number
of shares the beneficial ownership of which is deemed under subsection 4 hereof
to confer Voting Control of the Corporation (as determined without regard to
this Subsection 2) shall be considered from and after the date of acquisition by
such Person or Group Acting in Concert to be "excess shares" for purposes of
this Article ELEVENTH.  All shares deemed to be excess shares shall thereafter
no longer be entitled to vote on any matter or to take other shareholder action.
If, after giving effect to the first two sentences of this Subsection 2, any
Person or Group Acting in Concert still shall be deemed to be in Voting Control
of the Corporation based on the number of votes then entitled to be cast (rather
than the number of issued and outstanding shares of common stock of the
Corporation), then shares held in excess of the number of shares deemed to
confer Voting Control upon such Person or Group Acting in Concert also shall not
be entitled to vote on any matter or take any other shareholder action, but this
subsequent reduction in voting rights shall be effected only once.  The
provisions of this Subsection 2 deeming shares to be excess shares shall only
apply for so long as such shares shall be beneficially owned by such Person or
Group Acting in Concert who has acquired Voting Control.  Notwithstanding the
foregoing, shares held in excess of the number of shares the beneficial
ownership of which would otherwise be deemed under Subsection 4 to confer Voting
Control of the Corporation shall not be deemed to be excess shares if such
shares are held by a Tax-Qualified Employee Stock Benefit Plan.

          Subsection 3.  The provisions of this Article ELEVENTH shall be of no
further force and effect after the consummation of

                                       4
<PAGE>
 
a transaction in which another Person Acquires shares of capital stock of the
Corporation entitled to cast 80% or more of the votes which all shareholders are
entitled to cast (as determined without regard to the application of this
Article ELEVENTH) and such transaction was approved in advance by the board of
directors of the Corporation.

          Subsection 4.  For purposes of this Article ELEVENTH:

               A.  The term "Acquire" includes every type of acquisition,
     whether effected by purchase, exchange, operation of law or otherwise.

               B.  "Voting Control" means the sole or shared power to vote or to
     direct the voting of, or to dispose or to direct the disposition of, more
     than ten percent (10%) of the issued and outstanding common stock of the
     Corporation; provided that (i) the solicitation, holding and voting of
     proxies obtained by the board of directors of the Corporation pursuant to a
     solicitation under Regulation 14A of the General Rules and Regulations
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
     shall not constitute Voting Control, (ii) a Tax-Qualified Employee Stock
     Benefit Plan which holds more than 10 percent of the voting shares of the
     Corporation shall not be deemed to have Voting Control of the Corporation,
     (iii) any trustee, member of any administrative committee or employee
     beneficiary of a Tax-Qualified Employee Stock Benefit Plan shall not be
     deemed to have Voting Control of the Corporation either (A) as a result of
     their control of a Tax-Qualified Employee Stock Benefit Plan, and/or their
     beneficial interest in voting shares held by a Tax-Qualified Employee Stock
     Benefit Plan, or (B) as a result of the aggregation of both their
     beneficial interest in voting shares held by a Tax-Qualified Employee Stock
     Benefit Plan and voting shares held by such trustee, administrative
     committee member or employee beneficiary independent of a Tax-Qualified
     Employee Stock Benefit Plan, and (iv) any trustee which is a direct or
     indirect subsidiary of the Corporation shall not be deemed to have Voting
     Control of the Corporation as a result of having the right to vote more
     than ten percent (10%) of the issued and outstanding common stock of the
     Corporation.

               C.  "Group Acting in Concert" includes Persons seeking to combine
     or pool their voting or other interests in the voting shares for a common
     purpose, pursuant to any contract, understanding, relationship, agreement
     or other arrangement, whether written or otherwise, provided, that a "Group
     Acting in Concert" shall not include (i) the members of the board of
     directors of the Corporation solely as a result of their board membership,
     (ii) the members of the board of directors of the Corporation as a result
     of their solicitation, holding and voting of proxies obtained by them
     pursuant to a solicitation subject to rules and regulations

                                       5
<PAGE>
 
     promulgated under the Exchange Act or any successor statute or (iii) any
     member or all the members of the board of directors of the Corporation, and
     any Tax-Qualified Employee Stock Benefit Plan and the trustees,
     administrative committee members and employee beneficiaries thereof.

               D.  The term "Person" includes an individual, a Group Acting in
     Concert, a corporation, a partnership, an association, a joint stock
     company, a trust, an unincorporated organization or similar company, a
     syndicate or any other group formed for the purpose of acquiring,  holding
     or disposing of the equity securities of the Corporation.

               E.  The term "Tax-Qualified Employee Stock Benefit Plan" means
     any defined benefit plan or defined contribution plan of the Corporation or
     any subsidiary, such as an employee stock ownership plan, stock bonus plan,
     profit sharing plan or other plan, that, with its related trust, meets the
     requirements to be "qualified" under Section 401 of the Internal Revenue
     Code of 1986, as amended.

          Subsection 5.  This Article ELEVENTH shall not apply to the purchase
of securities of the Corporation by underwriters in connection with a public
offering of such securities by the Corporation or by a holder of shares of
capital stock of the Corporation with written consent of the board of directors
of the Corporation; provided, however, that purchasers of securities of the
Corporation from any underwriter shall be subject to the provisions of this
Article ELEVENTH.

     The board of directors of the Corporation shall have the power and duty to
determine, for purposes of this Article ELEVENTH, on the basis of information
known to the Board, if and when such other Person has acquired Voting Control of
the Corporation, and/or if any transaction is similar to, or has a similar
effect as, any of the transactions identified in this Article ELEVENTH.  Any
such determination shall be conclusive and binding for all purposes of this
Article ELEVENTH.

     TWELFTH.  No action required to be taken or which may be taken at any
annual or special meeting of shareholders of the Corporation may be taken
without a meeting, and the power of the shareholders of the Corporation to
consent in writing to action without a meeting is specifically denied.  The
presence, in person or by proxy, of shareholders entitled to cast at least a
majority of the votes which all shareholders are entitled to cast shall
constitute a quorum of shareholders at any annual or special meeting of
shareholders of the Corporation.

     THIRTEENTH.  The authority to make, amend, alter, change or repeal the By-
Laws of the Corporation is hereby expressly and solely granted to and vested in
the board of directors of the

                                       6
<PAGE>
 
Corporation, subject always to the power of the shareholders to change such
action by the affirmative vote of shareholders of the Corporation entitled to
cast at least 66-2/3 percent (66-2/3%) of the votes which all shareholders are
entitled to cast, except that provisions of the By-Laws of the Corporation
relating to limitations on directors' liabilities and indemnification of
directors, officers and others may not be amended to increase the exposure to
liability for directors or to decrease the indemnification of directors,
officers and others except by the affirmative vote of 66-2/3 percent (66-2/3%)
of the entire board of directors or by the affirmative vote of shareholders of
the Corporation entitled to cast at least 75 percent (75%) of the votes which
all shareholders are entitled to cast.

     FOURTEENTH.  The board of directors of the Corporation, when evaluating any
offer of another party to (a) make a tender or exchange offer for any equity
security of the Corporation, (b) merge or consolidate the Corporation with
another corporation, (c) purchase or otherwise acquire all or substantially all
of the properties and assets of the Corporation, or (d) engage in any
transaction similar to, or having similar effects as, any of the foregoing
transactions, shall, in connection with the exercise of its judgment in
determining what is in the best interests of the Corporation and its
shareholders, give due consideration to all relevant factors, including without
limitation the social and economic effects of the proposed transaction on the
employees, suppliers, customers and other constituents of the Corporation and
its subsidiaries and on the communities in which the Corporation and its
subsidiaries operate or are located, the business reputation of the other party,
and the board of directors' evaluation of the then value of the Corporation in a
freely negotiated sale and of the future prospects of the Corporation as an
independent entity.

     FIFTEENTH.  If any corporation, person, entity, or group becomes the
beneficial owner, directly or indirectly, of shares of capital stock of the
Corporation having the right to cast in the aggregate 25 percent (25%) or more
of all votes entitled to be cast by all issued and outstanding shares of capital
stock of the Corporation entitled to vote, such corporation, person, entity or
group shall within thirty (30) days thereafter offer to purchase all shares of
capital stock of the Corporation issued, outstanding and entitled to vote.  Such
offer to purchase shall be at a price per share equal to the highest price paid
for shares of the respective class or series of capital stock of the Corporation
purchased by such corporation, person, entity or group within the preceding
twelve months.  If such corporation, person, entity or group did not purchase
any shares of a particular class or series of capital stock of the Corporation
within the preceding twelve months, such offer to purchase shall be at a price
per share equal to the fair market value of such class or series of capital
stock on the date on which such corporation, person, entity or group becomes the
beneficial owner, directly or indirectly, of shares of capital stock of the

                                       7
<PAGE>
 
Corporation having the right to cast in the aggregate 25 percent (25%) or more
of all votes entitled to be cast by all issued and outstanding capital stock of
the Corporation.  Such offer shall provide that the purchase price for such
shares shall be payable in cash.  The provisions of this Article FIFTEENTH shall
not apply if 80 percent (80%) or more of the members of the board of directors
of the Corporation approve in advance the acquisition of beneficial ownership by
such corporation, person, entity or group, of shares of capital stock of the
Corporation having the right to cast in the aggregate 25 percent (25%) or more
of all votes entitled to be cast by all issued and outstanding shares of capital
stock of the Corporation.  The provisions of this Article FIFTEENTH shall be in
addition to and not in lieu of any rights granted under Subchapter E of Chapter
25 of the Pennsylvania Business Corporation Law and any amendment or restatement
of such section ("Subchapter E"); provided, however, that if the provisions of
this Article FIFTEENTH and Subchapter E are both applicable in any given
instance, the price per share to be paid for shares of capital stock of the
Corporation issued, outstanding and entitled to vote shall be the higher of the
price per share determined in accordance with this Article FIFTEENTH or the
price per share determined in accordance with the provisions of Subchapter E.

  SIXTEENTH.  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in its Articles of Incorporation in the manner
now or hereafter prescribed by statute and all rights conferred upon
shareholders and directors herein are hereby granted subject to this
reservation; provided, however, that the provisions set forth in Articles
SEVENTH, EIGHTH and TENTH through FOURTEENTH, inclusive, of these Articles of
Incorporation may not be repealed, altered or amended, in any respect
whatsoever, unless such repeal, alteration or amendment is approved by either
(a) the affirmative vote of at least 80 percent (80%) of votes cast by
shareholders entitled to vote or (b) the affirmative vote of 75 percent (75%) of
the members of the board of directors of the Corporation and the affirmative
vote of a majority of the votes cast by all shareholders of the Corporation then
entitled to vote.

ARTICLE I.  MEETINGS OF SHAREHOLDERS.
- ---------   ------------------------ 

     Section 101.  Place of Meetings.  All meetings of the shareholders shall be
     -----------   -----------------                                            
held at such place or places, within or without the Commonwealth of
Pennsylvania, as shall be determined by the Board of Directors from time to
time.

     Section 102.  Annual Meetings.
     -----------   --------------- 

          (a) Time and Date.  The annual meeting of the shareholders for the
              -------------                                                 
election of Directors and the transaction of such other business as may properly
come before the meeting shall be held at such date or hour as may be fixed by
the Board of Directors.  At each annual meeting of shareholders, directors shall
be elected, reports of the affairs of the Corporation shall be considered, and
any other business may be transacted which is within the power of the
shareholders.

          (b) Agenda for Annual Meeting.  Matters to be placed on the agenda for
              -------------------------                                         
consideration at annual meetings of shareholders may be determined by the Board
of Directors or by any shareholder entitled to vote for the election of
directors.  Matters proposed for the agenda by shareholders entitled to vote for
the election of directors shall be made by notice in writing, delivered or
mailed by first-class United States mail, postage prepaid, to the Secretary of
the Corporation not less than sixty (60) days prior to any annual meeting of
shareholders; provided, however, that if less than twenty-one (21) days' notice
of the meeting is given to shareholders, such written notice shall be delivered
or mailed, as prescribed, to the Secretary of the Corporation not later than the
close of the seventh day following the day on which notice of the meeting was
mailed to shareholders.  Notice of matters which are proposed by the Board of
Directors shall be given at any time by the Chairman of the Board or any other
appropriate officer.  Each notice made by shareholders shall set forth a brief
description of the business desired to be brought before the annual meeting.
The chairman of the meeting may determine and declare to the meeting that a
matter proposed for the agenda was not made in accordance with the foregoing
procedure, and if the chairman should so determine, the chairman shall so
declare to the meeting and the matter shall be disregarded.

     Section 103.  Special Meetings.  Special meetings of the shareholders may
     -----------   ----------------                                           
be called at any time by the Board of Directors in the manner provided herein.
Shareholders shall not have the

                                       1
<PAGE>
 
right to call special meetings of shareholders, except as specifically provided
by law.

     Section 104.  Conduct of Shareholders' Meetings.  At every meeting of the
     -----------   ---------------------------------                          
shareholders, the Chairman of the Board or, in the Chairman's absence, the
President or, in the President's absence, a chairman (who shall be one of the
officers, if any is present) chosen by a majority of the members of the Board of
Directors shall act as chairman of the meeting.  The chairman of the meeting
shall have any and all powers and authority necessary in the chairman's sole
discretion to conduct an orderly meeting and preserve order and to determine any
and all procedural matters, including imposing reasonable limits on the amount
of time at the meeting taken up in remarks by any one shareholder or group of
shareholders.  In addition, until the business to be completed at a meeting of
the shareholders is completed, the chairman of a meeting of the shareholders is
expressly authorized to temporarily adjourn and postpone the meeting from time
to time.  The Secretary of the Corporation or in the Secretary's absence, an
assistant secretary, shall act as secretary of all meetings of the shareholders.
In the absence at such meeting of the Secretary or assistant secretary, the
chairman of the meeting may appoint another person to act as secretary of the
meeting.

     Section 105.  Determination of Record Date.  The Board of Directors may fix
     -----------   ----------------------------                                 
a time prior to the date of any meeting of shareholders as a record date for the
determination of the shareholders entitled to notice of, or to vote at, the
meeting, which time, except in the case of an adjourned meeting, shall be not
more than 90 days prior to the date of the meeting of shareholders.  Only
shareholders of record on the date fixed shall be so entitled notwithstanding
any transfer of shares on the books of the Corporation after any record date
fixed as provided in this section.  The Board of Directors may similarly fix a
record date for the determination of shareholders of record for any other
purpose.  When a determination of shareholders of record has been made as
provided in this section for purposes of a meeting, the determination shall
apply to any adjournment thereof unless the Board of Directors fixes a new
record date for the adjourned meeting.

     Section 106.  Voting List.  The officer or agent having charge of the
     -----------   -----------                                            
transfer books for shares of the Corporation shall make a complete list of the
shareholders entitled to vote at any meeting of shareholders, arranged in
alphabetical order, with the address of and the number of shares held by each.
The list shall be produced and kept open at the time and place of the meeting
and shall be subject to the inspection of any shareholder during the whole time
of the meeting for the purposes thereof.

     Failure to comply with the requirements of this section shall not affect
the validity of any action taken at a meeting prior to a demand at the meeting
by any shareholder entitled to vote thereat to examine the list.  The original
share register or

                                       2
<PAGE>
 
transfer book, or a duplicate thereof kept in Pennsylvania, shall be prima facie
evidence as to who are the shareholders entitled to examine the list or share
register or transfer book or to vote at any meeting of shareholders.

       Section 107.  Judges of Election.  In advance of any meeting of
       -----------   ------------------                               
shareholders of the Corporation, the Board of Directors may appoint judges of
election, who need not be shareholders, to act at the meeting or any adjournment
thereof.  If judges of election are not so appointed, the presiding officer of
the meeting may, and on the request of any shareholder shall, appoint judges of
election at the meeting.  The number of judges shall be one (1) or three (3).
No person who is a candidate for office to be filled at the meeting shall act as
a judge of election.

     In the event any person appointed as a judge fails to appear or fails or
refuses to act, the vacancy may be filled by appointment made by the Board of
Directors in advance of convening the meeting or at the meeting by the presiding
officer thereof.

     The judges of election shall determine the number of shares outstanding and
the voting power of each, the shares represented at the meeting, the existence
of a quorum, the authenticity, validity and effect of proxies, receive votes or
ballots, hear and determine all challenges and questions in any way arising in
connection with the right to vote, count and tabulate all votes, determine the
result and do such acts as may be proper to conduct the election or vote with
fairness to all shareholders.  The judge or judges of election shall perform
their duties impartially, in good faith, to the best of their ability and as
expeditiously as is practical.  If there are three judges of election, the
decision, act or certificate of a majority shall be effective in all respects as
the decision, act or certificate of all.

     On request of the presiding officer of the meeting, or of any shareholder,
the judge or judges shall make a report in writing of any challenge or question
or matter determined by them, and execute a certificate of any fact found by
them.  Any report or certificate made by them shall be prima facie evidence of
the facts stated therein.

     Section 108.  No Consent of Shareholders in Lieu of Meeting.  No action
     -----------   ---------------------------------------------            
required to be taken or which may be taken at any annual or special meeting of
shareholders of the Corporation may be taken without a meeting, and the power of
the shareholders to consent in writing to action without a meeting is
specifically denied.

required by law in order to qualify as such Director.  Any Director shall
forthwith cease to be a Director when he/she no longer holds such shares, which
fact shall be reported to the Board of Directors by the Secretary, whereupon the
Board of Directors shall declare the seat of such Director vacated.

          (b) Other Qualifications.  Until January 1, 2003, it shall be a
              --------------------                                       
qualification for election and continued service as a Director of the
Corporation for each Director of the Corporation to observe the following
agreements and covenants:

<PAGE>
 
               (i)   Except for the Chairman and Chief Executive Officer,
     Directors of the Corporation shall not, either in their capacities as
     Directors, shareholders, or otherwise, directly or indirectly, encourage,
     solicit, initiate, or respond to any indications of interest, proposals or
     offers for any acquisition of, or change of control involving, the
     Corporation, whether by merger, sale of assets, or otherwise, or assist,
     aid or abet any person or persons with respect to such conduct.  In the
     event that any director is approached as described herein, any such contact
     shall be immediately referred in writing to the Chairman of the Board of
     Directors.

               (ii)  Directors of the Corporation shall not, either in their
     capacities as Directors, shareholders or otherwise, provide any third
     person with non-public information concerning the Corporation; and

               (iii) Directors of the Corporation shall not (in any capacity)
     publicly comment on the Corporation's strategic alternatives (including
     sale or possible sale of the Corporation) or on differences of view among
     members of the Board relating to the Corporation's strategic alternatives
     or on specific merger proposals or opportunities;

absent in any case either a direction from the entire Board of Directors by the
affirmative vote of 75% of the total number of directors then in office
(rounding up to the nearest whole number) or a written opinion of counsel to the
Corporation that such Director's fiduciary duty requires any such conduct.

     It is adopted as the corporate policy of this Corporation that the failure
by a Director to observe and comply with the foregoing covenants and agreements
shall subject the Director to removal by a vote of a majority of the Board of
Directors then in office or otherwise in accordance with law, unless such
Director has received a written opinion of the Corporation's counsel that such
Director's fiduciary duty requires such conduct.

     Section 204.  Classification of Directors.  The Board of Directors of the
     -----------   ---------------------------                                
Corporation shall be divided into three (3) classes, as nearly equal in number
as possible, as provided in the Corporation's Articles of Incorporation.

     Section 205.  Compensation of Directors.  No Director shall be entitled to
     -----------   -------------------------                                   
any salary as such; but the Board of Directors may fix, from time to time,
reasonable fees or other compensation, payable in cash, stock or other property,
for acting as a Director and reasonable fees to be paid each Director for
his/her services in attending meetings of the Board and meetings of committees
appointed by the Board.  The Corporation may reimburse Directors for expenses
related to their duties as members of the Board of Directors.

applicable law, as the Board of Directors shall from time to time designate or
as may be designated in any notice from the Secretary calling the meeting.  The
Board of Directors shall meet for reorganizational purposes at the first regular

regular meeting is not to be held at the time and place designated by the Board
of Directors, notice of such meeting, which need not specify the business to be
transacted thereat and which may be either verbal or in writing, shall be given
by the President to each member of the Board of Directors at least twenty-four
(24) hours before the time of the meeting.

     A majority of the members of the Board of Directors shall constitute a
quorum for the transaction of business.  If at the time fixed for the meeting,
including the meeting to organize the new Board following the annual meeting of
shareholders, a quorum is not present, the directors in attendance may adjourn
the meeting from time to time until a quorum is present.

     Except as otherwise provided in Section 209 or as otherwise provided
herein, a majority of Directors present and voting at any meeting of the Board
of Directors at which a quorum is present, shall decide each matter considered.

may be called by the Chairman of the Board, or at the request of a majority of
Directors then in office.  A special meeting of the Board of Directors shall be
deemed to be any meeting other than a regular meeting of the Board of Directors.
Notice of the time and place of every special meeting, which need not specify
the business to be transacted thereat, shall be given by the Chairman to each
member of the Board at least twenty-four (24) hours before the time of such

     transaction (a "Fundamental Transaction") involving the Corporation within
     the meaning of Chapter 19 of Title 15 of the Pennsylvania Business

indemnification rights available, this Article VII and any other provision of
these Bylaws inconsistent with such decreased exposure or increased
indemnification rights shall be amended, automatically and without any further
action on the part of shareholders or directors, to reflect such decreased

gain or loss upon the respective transfers of BCB's and Heritage's assets to
Holding Company in exchange solely for Holding Company Common Stock (including
any fractional share interests) and the assumption by Holding Company of the
respective liabilities of BCB and Heritage.

          4.  The basis of the respective BCB and Heritage assets in the hands
of Holding Company will be the same as the basis of such assets in the hands of
BCB and Heritage immediately prior to the Consolidation.

          5.  The holding period of the respective assets of BCB and Heritage to
be received by Holding Company will include the period during which the assets
were held by BCB and Heritage.

          6.  No gain or loss will be recognized by the shareholders of BCB or
Heritage on the receipt of Holding Company Common Stock (including any
fractional share interests) solely in exchange for their shares of BCB or
Heritage Common Stock, as the case may be.

          7.  The basis of the Holding Company Common Stock (including any
fractional share interests) to be received by the BCB and Heritage shareholders
in the Consolidation will be the same as the basis of the BCB or Heritage Common
Stock, as the case may be, surrendered in exchange therefor.

          8.  The holding period of the Holding Company Common Stock (including
any fractional share interests) to be received by the BCB and Heritage
shareholders in the Consolidation will include the period during which the BCB
and Heritage shareholders held their respective BCB and Heritage Common Stock,
provided the shares of such stock are held as a capital asset on the Effective
Date of the Consolidation.

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

                                       1
<PAGE>
 
Consolidation and then redeemed by Holding Company.  Such cash payments will be
treated as having been received as distributions in full payment in exchange for
the fractional share interests redeemed, as provided in IRC Section 302(a).  Any
gain or loss recognized by a BCB or Heritage shareholder will be a capital gain
or loss, provided the shares of BCB or Heritage Common Stock, as the case may
be, are held as a capital asset on the Effective Date of the Consolidation.

          10. As provided in IRC Section 381(c)(2) and related Treasury
regulations, Holding Company will succeed to and take into account the
respective earnings and profits, or deficit in earnings and profits, of BCB and
Heritage as of the Effective Date of the Consolidation.  Any deficit in the
earnings and profits of the parties will be used only to offset the earnings and
profits accumulated after the Consolidation.

          11. Pursuant to IRC Section 381(a) and related Treasury regulations,
Holding Company will succeed to and take into account the respective items of
BCB and Heritage described in IRC Section 381(c).  Such items will be taken into
account by Holding Company subject to the conditions and limitations of IRC
Sections 381, 382, 383, and 384 and the Treasury regulations thereunder.

                                                                    ------------


                             STOCK OPTION AGREEMENT
                             ----------------------

          THIS STOCK OPTION AGREEMENT ("Stock Option Agreement") dated November
18, 1997, is by and between HERITAGE BANCORP, INC., a Pennsylvania corporation
("Heritage") and BCB FINANCIAL SERVICES CORPORATION, a Pennsylvania corporation
("BCB").

                                   BACKGROUND
                                   ----------

          1.  Heritage and BCB desire to enter into an Agreement and Plan of
Consolidation, dated November 18, 1997 (the "Agreement"), providing, among other
things, for the creation by Heritage and BCB of a bank holding company which
will issue shares of its common stock to the shareholders of Heritage and BCB
(the "Consolidation").

          2.  As a condition to Heritage to enter into the Agreement, BCB is
granting to Heritage an option to purchase up to that number of shares of common
stock, par value $2.50 per share (the "Common Stock") of BCB as shall equal
19.9% of shares of Common Stock of BCB issued and outstanding as of the date
hereof, on the terms and conditions hereinafter set forth.

                                   AGREEMENT
                                   ---------

          In consideration of the foregoing and the mutual covenants and
agreements set forth herein, Heritage and BCB, intending to be legally bound
hereby, agree:

          1.  Grant of Option.  BCB hereby grants to Heritage, on the terms and
              ---------------                                                  
conditions set forth herein, the option to purchase (the "Option") up to 690,516
shares of Common Stock of BCB (as adjusted as set forth herein, the "Option
Shares") at a price per share (as adjusted as set forth herein, the "Option
Price") equal to $22.375, provided, however, that in no event shall the number
of Option Shares for which the Option is exercisable exceed 19.9% of the issued
and outstanding shares of BCB Common Stock without giving effect to any shares
subject to or issued pursuant to the Option.

          2.  Exercise of Option.
              ------------------ 

              (a) Provided that (i) Heritage shall not be, on the date of
exercise, in material breach of the agreements or covenants contained in the
Agreement, this Stock Option Agreement or the reciprocal Stock Option Agreement
by and between BCB and Heritage, and (ii) no preliminary or permanent injunction
or other order against the delivery of shares covered by the Option issued by
any court of competent jurisdiction in the United States shall be in effect on
the date of exercise, upon or after the occurrence of a Triggering Event (as
such term is hereinafter

                                       1
<PAGE>
 
defined) Heritage may exercise the Option, in whole or in part, at any time or
one or more times, from time to time; provided that the Option shall terminate
and be of no further force and effect upon the earliest to occur of (A) the
Effective Date of the Consolidation, as provided in the Agreement, (B)
termination of the Agreement in accordance with the terms thereof prior to the
occurrence of a Triggering Event or a Preliminary Triggering Event, other than a
termination of the Agreement pursuant to Section 6.01(d), unless in the case of
termination by BCB pursuant to Section 6.01(d), such termination is as a result
of a willful breach of the Agreement by Heritage (a termination pursuant to
Section 6.01(d), except a termination by BCB as a result of a willful breach by
Heritage, being referred to herein as a "Default Termination"), (C) 18 months
after the termination of the Agreement by Heritage or BCB pursuant to a Default
Termination, and (D) 18 months after termination of the Agreement (other than
pursuant to a Default Termination) following the occurrence of a Triggering
Event or a Preliminary Triggering Event; and provided, further, that any
purchase of shares upon exercise of the Option shall be subject to compliance
with applicable securities and banking laws.  The rights set forth in Section 3
hereof shall terminate when the right to exercise the Option terminates (other
than as a result of a complete exercise of the Option) as set forth above.

          (b) As used herein, the term "Triggering Event" means the occurrence
of any of the following events:

               (i)  a person or group (as such terms are defined in the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
     rules and regulations thereunder), other than Heritage or an affiliate of
     Heritage, acquires beneficial ownership (within the meaning of Rule 13d-3
     under the Exchange Act) of 25% or more of the then outstanding shares of
     Common Stock (excluding any shares eligible to be reported on Schedule 13G
     of the Securities and Exchange Commission); or

               (ii)  a person or group, other than Heritage or an affiliate of
     Heritage, enters into an agreement or letter of intent or memorandum of
     understanding with BCB or BCB shall have authorized, recommended or
     publicly proposed, or publicly announced an intention to authorize,
     recommend or propose, such an agreement or letter of intent or memorandum
     of understanding, pursuant to which such person or group or any affiliate
     of such person or group would (i) merge or consolidate, or enter into any
     similar transaction, with BCB, (ii) acquire all or substantially all of the
     assets or liabilities of BCB or all or substantially all of the assets or
     liabilities of Berks County Bank (or any successor subsidiary), the wholly-
     owned subsidiary of BCB ("BCB Bank"), or (iii) acquire beneficial ownership
     of securities representing, or the right to acquire beneficial ownership or
     to vote securities representing, 25% or more of

                                       2
<PAGE>
 
     the then outstanding shares of Common Stock (excluding any shares eligible
     to be reported on Schedule 13G of the Securities and Exchange Commission)
     or the then outstanding shares of common stock of BCB Bank.

          (c) As used herein, the term "Preliminary Triggering Event" means the
occurrence of any of the following events:

               (i)  a person or group (as such terms are defined in the Exchange
     Act and the rules and regulations thereunder), other than Heritage or an
     affiliate of Heritage, 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 Securities and Exchange Commission);

               (ii)  a person or group, other than Heritage or an affiliate of
     Heritage, publicly announces a bona fide proposal (including a written
     communication that is or becomes the subject of public disclosure) for (i)
     any merger, consolidation or acquisition of all or substantially all the
     assets or liabilities of BCB or all or substantially all the assets or
     liabilities of BCB Bank, or any other business combination involving BCB or
     BCB Bank, or (ii) 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 BCB Bank (collectively, a "Proposal"), and thereafter, if such
     Proposal has not been Publicly Withdrawn (as such term is hereinafter
     defined) at least 30 days prior to the meeting of shareholders of BCB
     called to vote on the Consolidation, BCB's shareholders fail to approve the
     Consolidation by the vote required by applicable law at the meeting of
     shareholders called for such purpose or such meeting has been cancelled; or

               (iii)  the Board of Directors of BCB shall (A) exercise the right
     granted to it in clause (i) of the second sentence of Section 4.06 of the
     Agreement, (B) fail to recommend the Consolidation, (C) recommend an
     Acquisition Transaction or (D) have withdrawn or modified in a manner
     adverse to Heritage the recommendation of the Board of Directors of BCB
     with respect to the Agreement and thereafter BCB's shareholders fail to
     approve the Consolidation by the vote required by law at the meeting of
     shareholders called for such purpose or such meeting is not scheduled or is
     cancelled without the written consent of Heritage; or

                                       3
<PAGE>
 
               (iv)  a person or group, other than Heritage or an affiliate of
     Heritage, makes a bona fide Proposal and thereafter, but before such
     Proposal has been Publicly Withdrawn, BCB shall have breached any
     representation, warranty, covenant or obligation contained in the Agreement
     and such breach would entitle Heritage to terminate the Agreement under
     Section 6.01(d) thereof (without regard to the cure period provided for
     therein unless such cure is promptly effected without jeopardizing
     consummation of the Consolidation 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.

          "Publicly Withdrawn" for purposes of this Section 2 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 BCB or in soliciting or inducing any other person
(other than Heritage or an affiliate of Heritage) to do so.

          Notwithstanding the foregoing, the obligation of BCB 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 BCB to issue the Option Shares or Heritage 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 provision to the contrary set forth herein, the Option
shall not expire or otherwise terminate with respect to the Option Shares
subject to any prior exercise.

          BCB shall notify Heritage promptly in writing of the occurrence of any
Triggering Event known to it, it being understood that the giving of such notice
by BCB shall not be a condition to the right of Heritage to exercise the Option.
BCB will not take any action which would have the effect of preventing or
disabling BCB from delivering the Option Shares to Heritage 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 Heritage wishes to exercise the Option,
Heritage shall send a written notice to BCB (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 between two and  ten business days
inclusive from

                                       4
<PAGE>
 
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 BCB.
          --------------------------- 
 
          (a) Subject to the last sentence of Section 2(a), at the request of
Heritage at any time commencing upon the first occurrence of a Repurchase Event
(as defined in Section 3(d)) and ending 18 months immediately thereafter, BCB
shall repurchase from Heritage (x) the Option and (y) all shares of Common Stock
purchased by Heritage pursuant hereto with respect to which Heritage then has
beneficial ownership.  The date on which Heritage 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 Purchase Price paid by Heritage for any shares
     of Common Stock acquired pursuant to the Option with respect to which
     Heritage then has beneficial ownership;

               (ii)  the excess, if any, of (x) the Applicable Price (as defined
     below) for each share of Common Stock over (y) 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 Heritage for each share of
     Common Stock with respect to which the Option has been exercised and with
     respect to which Heritage then has beneficial ownership, multiplied by the
     number of such shares.
 
          (b) If Heritage exercises it rights under this Section 3, BCB shall,
within ten (10) business days after the Request Date, pay the Section 3
Repurchase Consideration to Heritage in immediately available funds, and
contemporaneously with such payment, Heritage shall surrender to BCB the Option
and the certificate evidencing the shares of Common Stock purchased thereunder
with respect to which Heritage then has beneficial ownership, and Heritage 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.  Notwithstanding the foregoing, to the
extent that prior notification to or approval of any banking

                                       5
<PAGE>
 
agency or department of any federal or state government, including without
limitation the FRB, the OCC, the FDIC, 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, Heritage shall have the
ongoing option to revoke its request for repurchase pursuant to Section 3, in
whole or in part, or to require that BCB 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 (and each party shall cooperate with the other in
the filing of any such notice or application and the obtaining of any such
approval), in which case the ten (10) business day period of time that would
otherwise run pursuant to the preceding sentence 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.  If any Regulatory Authority
disapproves of any part of BCB's proposed repurchase pursuant to this Section 3,
BCB shall promptly give notice of such fact to Heritage.  If any Regulatory
Authority prohibits the repurchase pursuant to this Section 3, BCB shall
promptly give notice of such fact to Heritage.  If any Regulatory Authority
prohibits the repurchase in part but not in whole, then Heritage shall have the
right (i) to revoke the repurchase request or (ii) to the extent permitted by
such Regulatory Authority, determine whether the repurchase should apply to the
Option and/or Option Shares and to what extent to each, and Heritage 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.  Heritage shall notify
BCB 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 groups described in 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 Nasdaq Stock Market during the 40 business days
preceding the Request Date; provided, however, that in the event of a sale of
less than all of BCB'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 BCB as determined by a nationally-recognized investment
banking firm selected by Heritage, divided by the number of shares of Common
Stock

                                       6
<PAGE>
 
outstanding at the time of such sale.  If the consideration to be offered, paid
or received pursuant to either of the foregoing 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 Heritage and reasonably acceptable to BCB, 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 such terms are defined in the Exchange Act and the rules and
regulations thereunder), other than Heritage or an affiliate of Heritage,
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) BCB shall have merged or
consolidated with any person, other than Heritage or an affiliate of Heritage,
and shall not be the surviving or continuing corporation of such merger or
consolidation, (iii) any person, other than Heritage or an affiliate of
Heritage, shall have merged into BCB and BCB 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 BCB 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 (iv) BCB shall have sold or otherwise transferred more than 25%
of its consolidated assets to any person, other than Heritage or an affiliate of
Heritage.

     4.   Payment and Delivery of Certificates.  At any Closing hereunder,
          ------------------------------------                            
(a) Heritage will make payment to BCB of the aggregate price for the Option
Shares so purchased by wire transfer of immediately available funds to an
account designated by BCB, (b) BCB will deliver to Heritage a stock certificate
or certificates representing the number of Option Shares so purchased,
registered in the name of Heritage or its designee, in such denominations as
were specified by Heritage in its notice of exercise, and (c) Heritage 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

                                       7
<PAGE>
 
     to such time unless BCB Financial Services Corporation 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.  Upon or after the occurrence of a
               -------------------                                    
Triggering Event and upon receipt of a written request from Heritage, BCB shall
prepare and file as soon as practicable a registration statement under the
Securities Act of 1933 (the "Securities Act") with the Securities and Exchange
Commission covering the Option and such number of Option Shares as Heritage
shall specify in its request, and BCB 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 and the Option Shares, provided that Heritage
shall in no event have the right to have more than one such registration
statement become effective, and provided further that BCB shall not be required
to prepare and file any such registration statement in connection with any
proposed sale with respect to which counsel to BCB delivers to BCB and to
Heritage its opinion to the effect that no such filing is required under
applicable laws and regulations with respect to such sale or disposition;
provided further, however, that BCB may delay any registration of Option Shares
above for a period not exceeding 90 days in the event that BCB shall in good
faith determine that any such registration would adversely affect an offering or
contemplated offering of securities by BCB.  Heritage shall provide all
information reasonably requested by BCB for inclusion in any registration
statement to be filed hereunder.  In connection with such filing, BCB shall use
its reasonable best efforts to cause to be delivered to Heritage such
certificates, opinions, accountant's letters and other documents as Heritage
shall reasonably request and as are customarily provided in connection with
registration of securities under the Securities Act.  BCB shall provide to
Heritage such number of copies of the preliminary prospectus and final
prospectus and any amendments and supplements thereto as Heritage may reasonably
request.

          All reasonable expenses incurred by BCB 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 BCB and blue sky fees and expenses, shall be paid by BCB.
Underwriting discounts and commissions to brokers and dealers relating to the
Option Shares, fees and disbursements of counsel to Heritage and any other
expenses incurred by Heritage in connection with such filing shall be borne by
Heritage.  In connection with such filing, BCB shall indemnify and hold harmless
Heritage against any losses, claims, damages or liabilities, joint or several,
to which Heritage 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

                                       8
<PAGE>
 
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
BCB will reimburse Heritage for any legal or other expense reasonably incurred
by Heritage in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that BCB 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 behalf of Heritage specifically for use
in the preparation thereof.  Heritage will indemnify and hold harmless BCB 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 Heritage for use
in the preparation of such preliminary or final registration statement or such
amendment or supplement thereto; and Heritage will reimburse BCB for any legal
or other expense reasonably incurred by BCB in connection with investigating or
defending any such loss, claim, damage, liability or action.  Notwithstanding
anything to the contrary contained herein, 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

reasonable best efforts to make all filings with, and to obtain consents of, all

13D with the Securities and Exchange Commission under the Exchange Act which
discloses the rights of Heritage hereunder.

          8.   Representations and Warranties of BCB.  BCB hereby represents and
               -------------------------------------                            
warrants to Heritage as follows:

               (a) Due Authorization.  BCB 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 BCB. This Stock Option Agreement
constitutes a legal, valid and binding obligation of BCB, enforceable against
BCB in accordance with its terms (except as may be limited by applicable
bankruptcy, insolvency,

                                       9
<PAGE>
 
reorganization, moratorium, fraudulent transfer and similar laws of general
applicability relating to or affecting creditors' rights or by general equity
principles).

               (b) Authorized Shares.  BCB 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.

          9.   Representations and Warranties of Heritage.  Heritage hereby
               ------------------------------------------                  
represents and warrants to BCB that Heritage has full corporate power and
authority to execute, deliver and perform this Stock Option Agreement and all

Option Agreement has been duly taken by Heritage.  This Stock Option  Agreement
constitutes a legal, valid and binding obligation of Heritage, enforceable
against Heritage in accordance with its terms (except as may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and similar laws of general applicability relating to or affecting
creditors' rights or by general equity principles).

          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.  Heritage 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 a subsidiary of Heritage.  Heritage
represents that it is acquiring the Option for Heritage's own account and not
with a view to, or for sale in connection with, any distribution of the Option
or the Option Shares.  Heritage is aware that neither the Option nor the Option
Shares is the subject of a registration statement filed with, and declared
effective by, the Securities and Exchange Commission 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) thereof and
the representations and warranties made by Heritage 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

                                       10

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
force and effect.

                             STOCK OPTION AGREEMENT
                             ----------------------

     THIS STOCK OPTION AGREEMENT ("Stock Option Agreement") dated November 18,
1997, is by and between BCB FINANCIAL SERVICES CORPORATION, a Pennsylvania
corporation ("BCB") and HERITAGE BANCORP, INC., a Pennsylvania corporation
("HERITAGE").

                                   BACKGROUND
                                   ----------

     1.  BCB and Heritage desire to enter into an Agreement and Plan of
Consolidation, dated November 18, 1997 (the "Agreement"), providing, among other
things, for the creation by BCB and Heritage of a bank holding company which
will issue shares of its common stock to the shareholders of BCB and Heritage
(the "Consolidation").

     2.  As a condition to BCB to enter into the Agreement, Heritage is granting
to BCB an option to purchase up to that number of shares of common stock, par
value $5.00 per share (the "Common Stock") of Heritage as shall equal 19.9% of
shares of Common Stock of Heritage issued and outstanding as of the date hereof,
on the terms and conditions hereinafter set forth.

                                   AGREEMENT
                                   ---------

     In consideration of the foregoing and the mutual covenants and agreements
set forth herein, BCB and Heritage, intending to be legally bound hereby, agree:

     1.  Grant of Option.  Heritage hereby grants to BCB, on the terms and
         ---------------                                                  
conditions set forth herein, the option to purchase (the "Option") up to 947,041
shares of Common Stock of Heritage (as adjusted as set forth herein, the "Option
Shares") at a price per share (as adjusted as set forth herein, the "Option
Price") equal to $22.875, provided, however, that in no event shall the number
of Option Shares for which the Option is exercisable exceed 19.9% of the issued
and outstanding shares of Heritage Common Stock without giving effect to any
shares subject to or issued pursuant to the Option.

     2.  Exercise of Option.
         ------------------ 

         (a) Provided that (i) BCB shall not be, on the date of exercise, in
material breach of the agreements or covenants contained in the Agreement, this
Stock Option Agreement or the reciprocal Stock Option Agreement by and between
Heritage and BCB, and (ii) no preliminary or permanent injunction or other order
against the delivery of shares covered by the Option issued by any court of
competent jurisdiction in the United States shall be in effect on the date of
exercise, upon or after the occurrence of a Triggering Event (as such term is
hereinafter

                                       1
<PAGE>
 
defined) BCB may exercise the Option, in whole or in part, at any time or one or
more times, from time to time; provided that the Option shall terminate and be
of no further force and effect upon the earliest to occur of (A) the Effective
Date of the Consolidation, as provided in the Agreement, (B) termination of the
Agreement in accordance with the terms thereof prior to the occurrence of a
Triggering Event or a Preliminary Triggering Event, other than a termination of
the Agreement pursuant to Section 6.01(d), unless in the case of termination by
Heritage pursuant to Section 6.01(d), such termination is as a result of a
willful breach of the Agreement by BCB (a termination pursuant to Section
6.01(d), except a termination by Heritage as a result of a willful breach by
BCB, being referred to herein as a "Default Termination"), (C) 18 months after
the termination of the Agreement by BCB or Heritage pursuant to a Default
Termination, and (D) 18 months after termination of the Agreement (other than
pursuant to a Default Termination) following the occurrence of a Triggering
Event or a Preliminary Triggering Event; and provided, further, that any
purchase of shares upon exercise of the Option shall be subject to compliance
with applicable securities and banking laws.  The rights set forth in Section 3
hereof shall terminate when the right to exercise the Option terminates (other
than as a result of a complete exercise of the Option) as set forth above.

         (b) As used herein, the term "Triggering Event" means the occurrence 
of any of the following events:

             (i)  a person or group (as such terms are defined in the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
     rules and regulations thereunder), other than BCB or an affiliate of BCB,
     acquires beneficial ownership (within the meaning of Rule 13d-3 under the
     Exchange Act) of 25% or more of the then outstanding shares of Common Stock
     (excluding any shares eligible to be reported on Schedule 13G of the
     Securities and Exchange Commission); or

             (ii)  a person or group, other than BCB or an affiliate of BCB,
     enters into an agreement or letter of intent or memorandum of understanding
     with Heritage or Heritage shall have authorized, recommended or publicly
     proposed, or publicly announced an intention to authorize, recommend or
     propose, such an agreement or letter of intent or memorandum of
     understanding, pursuant to which such person or group or any affiliate of
     such person or group would (i) merge or consolidate, or enter into any
     similar transaction, with Heritage, (ii) acquire all or substantially all
     of the assets or liabilities of Heritage or all or substantially all of the
     assets or liabilities of Heritage National Bank (or any successor
     subsidiary), the wholly-owned subsidiary of Heritage ("Heritage Bank"), or
     (iii) acquire beneficial ownership of securities representing, or the right
     to acquire beneficial ownership

                                       2
<PAGE>
 
     or to vote securities representing, 25% or more of the then outstanding
     shares of Common Stock (excluding any shares eligible to be reported on
     Schedule 13G of the Securities and Exchange Commission) or the then
     outstanding shares of common stock of Heritage Bank.

         (c) As used herein, the term "Preliminary Triggering Event" means
the occurrence of any of the following events:

             (i)  a person or group (as such terms are defined in the Exchange
     Act and the rules and regulations thereunder), other than BCB or an
     affiliate of BCB, 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 Securities and Exchange Commission);
 
             (ii) a person or group, other than BCB or an affiliate of BCB,
     publicly announces a bona fide proposal (including a written communication
     that is or becomes the subject of public disclosure) for (i) any merger,
     consolidation or acquisition of all or substantially all the assets or
     liabilities of Heritage or all or substantially all the assets or
     liabilities of Heritage Bank, or any other business combination involving
     Heritage or Heritage Bank, or (ii) 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 Heritage Bank (collectively, a "Proposal"), and thereafter,
     if such Proposal has not been Publicly Withdrawn (as such term is
     hereinafter defined) at least 30 days prior to the meeting of shareholders
     of Heritage called to vote on the Consolidation, Heritage's shareholders
     fail to approve the Consolidation by the vote required by applicable law at
     the meeting of shareholders called for such purpose or such meeting has
     been cancelled; or

             (iii) the Board of Directors of Heritage shall (A) exercise the
     right granted to it in clause (i) of the second sentence of Section 4.06 of
     the Agreement, (B) fail to recommend the Consolidation, (C) recommend an
     Acquisition Transaction or (D) have withdrawn or modified in a manner
     adverse to BCB the recommendation of the Board of Directors of Heritage
     with respect to the Agreement and thereafter Heritage's shareholders fail
     to approve the Consolidation by the vote required by law at the meeting of
     shareholders called for such purpose or such meeting is not scheduled or is
     cancelled without the written consent of BCB; or

                                       3
<PAGE>
 
             (iv)  a person or group, other than BCB or an affiliate of BCB,
     makes a bona fide Proposal and thereafter, but before such Proposal has
     been Publicly Withdrawn, Heritage shall have breached any representation,
     warranty, covenant or obligation contained in the Agreement and such breach
     would entitle BCB to terminate the Agreement under Section 6.01(d) thereof
     (without regard to the cure period provided for therein unless such cure is
     promptly effected without jeopardizing consummation of the Consolidation
     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.

          "Publicly Withdrawn" for purposes of this Section 2 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 Heritage or in soliciting or inducing any other
person (other than BCB or an affiliate of BCB) to do so.

          Notwithstanding the foregoing, the obligation of Heritage 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 Heritage to issue the Option Shares or BCB
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 provision to the contrary set forth herein, the Option
shall not expire or otherwise terminate with respect to the Option Shares
subject to any prior exercise.

          Heritage shall notify BCB promptly in writing of the occurrence of any
Triggering Event known to it, it being understood that the giving of such notice
by Heritage shall not be a condition to the right of BCB to exercise the Option.
Heritage will not take any action which would have the effect of preventing or
disabling Heritage from delivering the Option Shares to BCB 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 BCB wishes to exercise the Option, BCB shall
send a written notice to Heritage (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 between two and ten business days inclusive from
the

                                       4
<PAGE>
 
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 Heritage.
          -------------------------------- 
 
          (a) Subject to the last sentence of Section 2(a), at the request of
BCB at any time commencing upon the first occurrence of a Repurchase Event (as
defined in Section 3(d)) and ending 18 months immediately thereafter, Heritage
shall repurchase from BCB (x) the Option and (y) all shares of Common Stock
purchased by BCB pursuant hereto with respect to which BCB then has beneficial
ownership.  The date on which BCB 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 Purchase Price paid by BCB for any shares of
     Common Stock acquired pursuant to the Option with respect to which BCB then
     has beneficial ownership;

               (ii)  the excess, if any, of (x) the Applicable Price (as defined
     below) for each share of Common Stock over (y) 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 BCB for each share of Common
     Stock with respect to which the Option has been exercised and with respect
     to which BCB then has beneficial ownership, multiplied by the number of
     such shares.
 
          (b) If BCB exercises it rights under this Section 3, Heritage shall,
within ten (10) business days after the Request Date, pay the Section 3
Repurchase Consideration to BCB in immediately available funds, and
contemporaneously with such payment, BCB shall surrender to Heritage the Option
and the certificate evidencing the shares of Common Stock purchased thereunder
with respect to which BCB then has beneficial ownership, and BCB 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.  Notwithstanding the foregoing, 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 FRB, the OCC, the FDIC, or
the

                                       5
<PAGE>
 
respective staffs thereof (the "Regulatory Authority"), is required in
connection with the payment of all or any portion of the Section 3 Repurchase
Consideration, BCB shall have the ongoing option to revoke its request for
repurchase pursuant to Section 3, in whole or in part, or to require that
Heritage 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 (and each party shall cooperate with the other in the filing of any such
notice or application and the obtaining of any such approval), in which case the
ten (10) business day period of time that would otherwise run pursuant to the
preceding sentence 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.  If any Regulatory Authority disapproves of any part of Heritage's
proposed repurchase pursuant to this Section 3, Heritage shall promptly give
notice of such fact to BCB.  If any Regulatory Authority prohibits the
repurchase pursuant to this Section 3, Heritage shall promptly give notice of
such fact to BCB.  If any Regulatory Authority prohibits the repurchase in part
but not in whole, then BCB shall have the right (i) to revoke the repurchase
request or (ii) to the extent permitted by such Regulatory Authority, determine
whether the repurchase should apply to the Option and/or Option Shares and to
what extent to each, and BCB 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.  BCB shall notify Heritage 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 groups described in 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 Nasdaq Stock Market during the 40 business days
preceding the Request Date; provided, however, that in the event of a sale of
less than all of Heritage'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 Heritage as determined by a nationally-recognized investment
banking firm selected by BCB, divided by the number of shares of Common Stock
outstanding at the time of such sale.  If the consideration to be

                                       6
<PAGE>
 
offered, paid or received pursuant to either of the foregoing 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 BCB and reasonably acceptable to Heritage, 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 such terms are defined in the Exchange Act and the rules and
regulations thereunder), other than BCB or an affiliate of BCB, 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) Heritage shall have merged or
consolidated with any person, other than BCB or an affiliate of BCB, and shall
not be the surviving or continuing corporation of such merger or consolidation,
(iii) any person, other than BCB or an affiliate of BCB, shall have merged into
Heritage and Heritage 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 Heritage 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
(iv) Heritage shall have sold or otherwise transferred more than 25% of its
consolidated assets to any person, other than BCB or an affiliate of BCB.

       4. Payment and Delivery of Certificates.  At any Closing hereunder,
          ------------------------------------                            
(a) BCB will make payment to Heritage of the aggregate price for the Option
Shares so purchased by wire transfer of immediately available funds to an
account designated by Heritage, (b) Heritage will deliver to BCB a stock
certificate or certificates representing the number of Option Shares so
purchased, registered in the name of BCB or its designee, in such denominations
as were specified by BCB in its notice of exercise, and (c) BCB 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 Heritage Bancorp, Inc.
     receives an opinion of counsel acceptable to it stating that an

                                       7
<PAGE>
 
     exemption from the registration provisions of the Act is available for such
     transfer."

          5.   Registration Rights.  Upon or after the occurrence of a
               -------------------                                    
Triggering Event and upon receipt of a written request from BCB, Heritage shall
prepare and file as soon as practicable a registration statement under the
Securities Act of 1933 (the "Securities Act") with the Securities and Exchange
Commission covering the Option and such number of Option Shares as BCB shall
specify in its request, and Heritage 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 and the Option Shares, provided that BCB shall
in no event have the right to have more than one such registration statement
become effective, and provided further that Heritage shall not be required to
prepare and file any such registration statement in connection with any proposed
sale with respect to which counsel to Heritage delivers to Heritage and to BCB
its opinion to the effect that no such filing is required under applicable laws
and regulations with respect to such sale or disposition; provided further,
however, that Heritage may delay any registration of Option Shares above for a
period not exceeding 90 days in the event that Heritage shall in good faith
determine that any such registration would adversely affect an offering or
contemplated offering of securities by Heritage.  BCB shall provide all
information reasonably requested by Heritage for inclusion in any registration
statement to be filed hereunder.  In connection with such filing, Heritage shall
use its reasonable best efforts to cause to be delivered to BCB such
certificates, opinions, accountant's letters and other documents as BCB shall
reasonably request and as are customarily provided in connection with
registration of securities under the Securities Act.  Heritage shall provide to
BCB such number of copies of the preliminary prospectus and final prospectus and
any amendments and supplements thereto as BCB may reasonably request.

          All reasonable expenses incurred by Heritage 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 Heritage and blue sky fees and expenses, shall be paid by
Heritage.  Underwriting discounts and  commissions to brokers and dealers
relating to the Option Shares, fees and disbursements of counsel to BCB and any
other expenses incurred by BCB in connection with such filing shall be borne by
BCB.  In connection with such filing, Heritage shall indemnify and hold harmless
BCB against any losses, claims, damages or liabilities, joint or several, to
which BCB 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

                                       8
<PAGE>
 
required to be stated therein or necessary to make the statements therein not
misleading; and Heritage will reimburse BCB for any legal or other expense
reasonably incurred by BCB in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that Heritage
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 behalf of BCB
specifically for use in the preparation thereof.  BCB will indemnify and hold
harmless Heritage 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 BCB for use in the preparation of such preliminary or final
registration statement or such amendment or supplement thereto; and BCB will
reimburse Heritage for any legal or other expense reasonably incurred by
Heritage in connection with investigating or defending any such loss, claim,
damage, liability or action.  Notwithstanding anything to the contrary contained
herein, 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 BCB and Heritage 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, BCB shall file a report of beneficial ownership on Form 13D
with the Securities and Exchange Commission under the Exchange Act which
discloses the rights of BCB hereunder.

          8.   Representations and Warranties of Heritage.  Heritage hereby
               ------------------------------------------                  
represents and warrants to BCB as follows:

               (a) Due Authorization.  Heritage 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 Heritage.  This Stock Option  Agreement
constitutes a legal, valid and binding obligation of Heritage, enforceable
against Heritage in accordance with its terms (except as may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer and similar laws of general applicability relating to or affecting
creditors' rights or by general equity principles).

                                       9
<PAGE>
 
               (b) Authorized Shares.  Heritage 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.

          9.   Representations and Warranties of BCB.  BCB hereby represents and
               -------------------------------------                            
warrants to Heritage that BCB 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 BCB.  This Stock Option  Agreement constitutes a legal,
valid and binding obligation of BCB, enforceable against BCB in accordance with
its terms (except as may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer and similar laws of general
applicability relating to or affecting creditors' rights or by general equity
principles).

          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.  BCB 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 a subsidiary of BCB.  BCB represents
that it is acquiring the Option for BCB's own account and not with a view to, or
for sale in connection with, any distribution of the Option or the Option
Shares.  BCB is aware that neither the Option nor the Option Shares is the
subject of a registration statement filed with, and declared effective by, the
Securities and Exchange Commission 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) thereof and the
representations and warranties made by BCB 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

                                       10
<PAGE>
 
validity or enforceability of any other provisions of this Stock Option
Agreement, which shall remain in full force and effect.

          15.  Notices.  All notices, requests, consents and other

record.  Heritage shareholders will receive 1.05 shares for each Heritage share 
owned on the date of record.  The transaction, which is subject to regulatory 
approvals and the approval of BCB and Heritage shareholders, will be accounted 
for as a pooling of interests and will be a tax free reorganization.  The 
transaction is expected to close during the second quarter of 1998.

Nelson R. Oswald, Chairman and President of BCB, said the combination of BCB and
Heritage, two respected and well established organizations, will result in a 
stronger and larger organization that will better serve customers, shareholders,
local communities and employees.  Oswald emphasized that the number one goal of 
the new corporation would be to maintain a high level of personal service to its
customers through its two independent community banks, Heritage National Bank 
and Berks County Bank.  The combination will allow both banks to offer a broader
range of products and services to their customers.

Allen E. Keifer, President and CEO of Heritage, said the strengths of both 
Corporations will complement each other well.  BCB is recognized as one of the 
fastest growing financial corporations and Heritage is recognized for its high 
levels of profitability.  The combination of growth and profitability will 
benefit the shareholders of both Corporations in the future.  "Heritage has 
always dedicated itself to maximizing long-term shareholder value.  This 
combination will allow our shareholders to continue to benefit from solid 
earnings growth, which has been the fundamental key to our success in recent 
years."

BCB and Heritage, through their subsidiary banks, currently operate 19 community
offices in Berks, Montgomery, Schuylkill and Dauphin Counties. In addition, 
there are loan offices in Berks, Bucks, Chester, Lehigh, Montgomery and 
Schuylkill Counties.

Oswald and Kiefer jointly stated that "The affiliation of Heritage and BCB 
presents a unique opportunity that will allow for the subsidiary community banks
to remain independent and service their separate markets. The combination will 
result in operating efficiencies and increased profitability through the 
consolidation of back-room operations. This will permit our Banks to provide an 
even higher level of personalized services that the over 100,000 individual and 
business customers we serve have come to expect."

Oswald and Kiefer stated that the merger of BCB and Heritage is unique because 
- -- unlike most mergers which result in massive layoffs -- the anticipated growth
of the new organization will result in the likely creation of well over a 
hundred new jobs over the next few years.

Executive management of the new corporation will include Nelson R. Oswald, 
Chairman and Chief Executive Officer; Allen E. Kiefer, President and Chief 
Operating Officer; Robert D. McHugh, Jr., Executive Vice President and Chief 
Financial Officer and Richard A. Ketner, Executive Vice President and Chief 
Administrative Officer. Oswald will continue to be President and CEO of Berks 
County Bank and Kiefer will serve as President and CEO of Heritage National 
Bank.
