ITEM 5. OTHER EVENTS.
 
  On August 29, 1995, Community Bankshares, Inc., a New Hampshire corporation
("Community"), entered into an Agreement and Plan of Merger (the "Merger
Agreement") with Centerpoint Bank, a New Hampshire-chartered trust company
("Centerpoint"). A copy of the joint press release issued by Community and
Centerpoint on August 30, 1995 and the Merger Agreement are filed as exhibits
hereto and are incorporated by reference herein.
 
  Under the terms of the Merger Agreement, Community will form a New Hampshire
bank as a wholly owned subsidiary, which subsidiary will be merged with and
into Centerpoint, with Centerpoint as the surviving corporation (the
"Merger"). Upon the effectiveness of the Merger, each share of the common
stock, par value $1.00 per share, of Centerpoint ("Centerpoint Common Stock")
issued and outstanding immediately prior to the effectiveness of the Merger
(other than shares held by dissenting stockholders or owned by Community or
any of its subsidiaries or Centerpoint or any of its Subsidiaries) shall be
converted into and exchangeable for 1.073 shares of the common stock, par
value $1.00 per share, of Community ("Community Common Stock").
 
  The Agreement also provides that at the effective time of the Merger, each
then outstanding stock option to purchase Centerpoint Common Stock
("Centerpoint Option") pursuant to Centerpoint's 1989 Stock Option Plan (the
"Centerpoint Stock Option Plan") (with 77,500 options currently outstanding)
will be assumed by Community. Each Centerpoint Option so assumed shall be
exercisable (when vested) for that number of whole shares of Community Common
Stock equal to the product of the number of shares of Community Common Stock
covered by the Centerpoint Option multiplied by 1.073.
 
  As part of the Merger, Community and Centerpoint have also entered into a
Stock Option Agreement dated August 29, 1995 pursuant to which Centerpoint has
granted an option (the "Option") to Community to purchase up to 165,920 shares
of Centerpoint Common Stock (19.9% of the outstanding Centerpoint Common
Stock, including shares issuable pursuant to the Centerpoint Stock Option
Plan) under certain conditions, at a price of $12.00 per share, subject to
adjustment. Community conditioned its willingness to enter into the Merger
Agreement on receipt of the Option. A copy of the Option Agreement is filed as
an exhibit hereto and is incorporated by reference herein.
 
  The transaction, which is subject to customary closing conditions, has been
approved by the Boards of Directors of both Community and Centerpoint. It must
also be approved by the stockholders of Community and Centerpoint as well as
by regulatory authorities.

  Whereas, the respective Boards of Directors of Buyer and Seller have
approved the acquisition of Seller by Buyer pursuant to the merger of Buyer

waiver of the conditions to the parties' respective obligations hereunder, at
the Effective Time (as defined in Section 1.2 hereof), Buyer shall form the

with and into Seller. Seller shall be the surviving bank of the Merger (the

any property or right of Seller acquired or to be acquired by reason of, or as

  1.7 Option to Purchase Seller Common Stock. As part of the Merger and as a
condition to entering into this Agreement, Buyer and Seller have entered into
a Stock Option Agreement on the date hereof (the "Stock Option Agreement") in
the form attached hereto as Exhibit 1.7, giving Buyer the right to purchase
165,920 shares of Seller Common Stock, which shares would upon issuance equal

issuable pursuant to the Seller Stock Option Plan (as defined below).
 
                                  ARTICLE II
 
                             Conversion of Shares
 
  2.1 Conversion of Seller Common Stock. (a) At the Effective Time, each share
of the common stock, par value $1.00 per share, of Seller (the "Seller Common
Stock") issued and outstanding immediately prior to the Effective Time (other
than Dissenting Shares (as such term is defined in Section 2.4 hereof) and
other than Seller Common Stock then owned by Seller, any Seller subsidiary,
Buyer, or any Buyer subsidiary (in each case other than in a fiduciary
capacity or as a result of debts previously contracted)) shall, by virtue of
the Merger and without any action on the part of the holder thereof, be
converted into and exchangeable for 1.073 shares (the "Exchange Ratio") of the
common stock, par value $1.00 per share of Buyer ("Buyer Common Stock"). The
consideration to be received for each share of Seller Common Stock is referred
to herein as the "Merger Consideration".
 
  (b) All of the Seller Common Stock converted into Buyer Common Stock
pursuant to this Section 2.1 shall no longer be outstanding and shall
automatically be cancelled and shall cease to exist, and each certificate
(each a "Certificate") previously representing any such Seller Common Stock
shall thereafter represent the right to receive (i) the number of whole shares
of Buyer Common Stock and (ii) cash in lieu of fractional shares into which
the Seller Common Stock represented by such Certificate have been converted
pursuant to this Section 2.1 and Section 2.2 hereof. Certificates previously
representing Seller Common Stock shall be exchanged for certificates
representing whole shares of Buyer Common Stock and cash in lieu of fractional
shares issued in consideration therefor upon the surrender of such
Certificates in accordance with Section 2.2 hereof, without any interest
thereon. If prior to the Effective Time Buyer should split or combine its
common stock or other convertible securities, or pay a dividend or other
distribution in such common stock or other convertible securities, then the
Exchange Ratio shall be appropriately adjusted to reflect such split,
combination, dividend or distribution. All Seller Common Stock owned by
Seller, any Seller subsidiary, Buyer, or any Buyer subsidiary (in each case
other than in a fiduciary capacity or as a result of debts previously
contracted) shall, at the Effective Time, cease to exist, and the certificates
for such shares shall, as promptly as practicable thereafter, be cancelled
 
                                       2
<PAGE>
 
and no payments shall be made in consideration therefor. All shares of Buyer
Common Stock that are owned by Seller or any of the Seller Subsidiaries (in
each case other than in a fiduciary capacity or as a result of debts
previously contracted) shall become treasury stock of Buyer.
 
  2.2 Procedures for Exchange of Seller Common Stock for Merger Consideration.
 
  (a) Buyer to Make Shares Available. Buyer shall take all steps necessary on
and as of the Effective Time to deliver to the Exchange Agent (as hereinafter
defined), for the benefit of the holders of Certificates, for exchange in
accordance with this Section 2.2, certificates representing shares of Buyer
Common Stock and the cash in lieu of fractional shares to be paid pursuant to
Section 2.2(d) (such cash and certificates for shares of Buyer Common Stock,
together with any dividends or distributions with respect thereto being
hereinafter referred to as the "Exchange Fund") to be issued and paid in
exchange for outstanding Seller Common Stock in accordance with this
Agreement. The Exchange Agent shall be such banking institution or corporate
trust company reasonably satisfactory to Buyer as Seller shall appoint to act
as exchange agent hereunder. The Exchange Agent shall act as agent on behalf
of record holders (individually, a "Record Holder") of Seller Common Stock at
the Effective Time, other than Seller, any Seller Subsidiary, Buyer, or any
Buyer subsidiary (in each case other than in a fiduciary capacity or as a
result of debts previously contracted), or any Person holding Dissenting
Shares.
 
  (b) Exchange of Certificates. Within three business days after the Effective
Time, Buyer shall take all steps necessary to cause the Exchange Agent to mail
to each Record Holder of a Certificate or Certificates, a form letter of
transmittal for return to the Exchange Agent and instructions for use in
effecting the surrender of the Certificates for certificates representing the
Buyer Common Stock and the cash in lieu of fractional shares into which the
Seller Common Stock represented by such Certificates shall have been converted
as a result of the Merger. The form letter (which shall be subject to the
reasonable approval of Seller) shall specify that delivery shall be effected,
and risk of loss and title to the Certificates shall pass, only upon delivery
of the Certificates to the Exchange Agent. Upon surrender of a Certificate for
exchange and cancellation to the Exchange Agent, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled
to receive in exchange therefor (x) a certificate for the number of whole
shares of Buyer Common Stock to which such holder of Seller Common Stock shall
have become entitled pursuant to the provisions of this Article II and (y) a
check representing the amount of cash in lieu of the fractional shares, if
any, which such holder has the right to receive in respect of Certificates
surrendered pursuant to the provisions of this Article II, and the
Certificates so surrendered shall forthwith be cancelled. In the event any
Certificate shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the person claiming such certificate to be lost,
stolen or destroyed and, if required by Buyer, the posting by such person of a
bond in such amount as Buyer may direct as indemnity against any claim that
may be made against it with respect to such certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed certificate the
Merger Consideration deliverable in respect thereof pursuant to Section 2.1
hereof.
 
  (c) Rights of Certificate Holders after the Effective Time. The holder of a
Certificate that prior to the Merger represented issued and outstanding Seller
Common Stock shall have no rights, after the Effective Time, with respect to
such Seller Common Stock except to surrender the Certificate in exchange for
the Merger Consideration as provided in this Agreement or to perfect the
rights of appraisal as a holder of Dissenting Shares that such holder may have
pursuant to the applicable provisions of New Hampshire law. No dividends or
distributions shall be payable with respect to any Certificate until such
Certificate shall have been exchanged for certificates representing shares of
Buyer Common Stock; at the time of such exchange, the holder of the
Certificate shall be entitled to receive the payment of all dividends, if any,
that have been declared and paid with respect to the shares of Buyer Common
Stock represented by such Certificate between the Closing Date and the date of
such exchange.
 
  (d) Fractional Shares. Notwithstanding anything to the contrary contained
herein, no certificates or scrip representing fractional shares of Buyer
Common Stock shall be issued upon the surrender for exchange of Certificates,
no dividend or distribution with respect to Buyer Common Stock shall be
payable on or with respect to any fractional share, and such fractional share
interests shall not entitle the owner thereof to vote or to any
 
                                       3
<PAGE>
 
other rights of a stockholder of Buyer. In lieu of the issuance of any such
fractional share, Buyer shall pay to each former holder of Seller Common Stock
who otherwise would be entitled to receive a fractional share of Buyer Common
Stock, an amount in cash determined by multiplying (i) the average closing
sale price of Buyer Common Stock on the Stock Exchange as reported by The Wall
Street Journal for the five trading days immediately preceding the date of the
Effective Time (the "Last Closing Price") by (ii) the fraction of a share of
Buyer Common Stock which such holder would otherwise be entitled to receive
pursuant to Section 2.2(b) hereof. No interest will be paid on the cash which
the holders of such fractional shares shall be entitled to receive upon such
delivery.
 
  (e) Surrender by Persons Other than Record Holders. If the Person
surrendering a Certificate and signing the accompanying letter of transmittal
is not the Record Holder thereof, then it shall be a condition of the payment
of the Merger Consideration that such Certificate is properly endorsed to such
Person or is accompanied by appropriate stock powers, in either case signed
exactly as the name of the Record Holder appears on such Certificate, and is
otherwise in proper form for transfer, or is accompanied by appropriate
evidence of the authority of the Person surrendering such Certificate and
signing the letter of transmittal to do so on behalf of the Record Holder and
that the person requesting such exchange shall pay to the Exchange Agent in
advance any transfer or other taxes required by reason of the payment to a
person other than the registered holder of the Certificate surrendered, or
required for any other reason, or shall establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not payable.
 
  (f) Closing of Transfer Books. From and after the Effective Time, there
shall be no transfers on the stock transfer books of Seller of the Seller
Common Stock which were outstanding immediately prior to the Effective Time.
If, after the Effective Time, Certificates representing such shares are
presented for transfer to the Exchange Agent, they shall be exchanged for the
Merger Consideration and cancelled as provided in this Article II.
 
  (g) Return of Exchange Fund. At any time following the 12 month period after
the Effective Time, Buyer shall be entitled to require the Exchange Agent to
deliver to it any portions of the Exchange Fund which had been made available
to the Exchange Agent and not disbursed to holders of Certificates (including,
without limitation, all interest and other income received by the Exchange
Agent in respect of all funds made available to it), and thereafter such
holders shall be entitled to look to Buyer (subject to abandoned property,
escheat and other similar laws) only as general creditors thereof with respect
to any Merger Consideration that may be payable upon due surrender of the
Certificates held by them. Notwithstanding the foregoing, neither Buyer nor
the Exchange Agent shall be liable to any holder of a Certificate for any
Merger Consideration delivered in respect of such Certificate to a public
official pursuant to any abandoned property, escheat or other similar law.
 
  2.3 Buyer Sub Common Stock. Each share of common stock of Buyer Sub issued
and outstanding immediately prior to the Effective Time shall be converted
into one (1) share of common stock of the Surviving Bank at the Effective Time
and shall be held by Buyer.
 
  2.4 Dissenters' Rights. (a) Notwithstanding anything in this Agreement to
the contrary and unless otherwise provided by applicable law, Seller Common
Stock which is issued and outstanding immediately prior to the Effective Time
and which is owned by stockholders who, pursuant to applicable law, have
properly perfected their right to dissent and demand payment within the
meaning of New Hampshire Revised Statutes Annotated (the "NHRSA") 293-A:13.01
et seq. (the "Dissenting Shares") shall not be converted into the right to
receive, or be exchangeable for, the Merger Consideration, unless and until
such stockholders shall have failed to perfect or shall have effectively
withdrawn or lost their right to dissent and demand payment under applicable
law. If any such holder shall have failed to perfect or shall have effectively
withdrawn or lost such right to dissent, the Seller Common Stock of such
holder shall thereupon be deemed to have been converted into and be
exchangeable for, at the Effective Time, the right to receive the Merger
Consideration pursuant to Section 2.1 hereof. Holders of Seller Common Stock
who become entitled pursuant to the provisions of the NHRSA to payment for
their shares of Seller Common Stock under the provisions thereof shall receive
payment from the Surviving Bank and such shares of Seller Common Stock shall
be cancelled.
 
                                       4
<PAGE>
 
  (b) Seller shall give Buyer (i) prompt notice of any demands for payment of
shares received by Seller, withdrawals of such demands, and any other
instruments served in connection with such demands pursuant to the NHRSA and
received by Seller and (ii) the opportunity to direct all negotiations and
proceedings with respect to demands for payment for shares under the NHRSA
consistent with the obligations of Seller thereunder. Seller shall not, except
with the prior written consent of Buyer, (x) make any payment with respect to
any demands for payment for shares, (y) offer to settle or settle any such
demands or (z) waive any failure to timely deliver a written demand for
payment for shares in accordance with the NHRSA.
 
  2.5 Stock Options. (a) At the Effective Time, each then outstanding stock
option to purchase Seller Common Stock ("Seller Option") pursuant to the
Seller's 1989 Stock Option Plan (the "Seller Stock Option Plan") (it being
understood that the aggregate number shares of Seller Common Stock subject to
purchase pursuant to the exercise of such Seller Options is not and shall not
be more than 77,500), whether vested or unvested, will be assumed by Buyer.
Each Seller Option so assumed by Buyer under this Agreement shall continue to
have, and be subject to, the same terms and conditions set forth in the Seller
Stock Option Plan immediately prior to the Effective Time, except that (i)
such Seller Option shall be exercisable (when vested) for that number of whole
shares of Buyer Common Stock equal to the product of the number of shares of
Seller Common Stock covered by the Seller Option multiplied by the Exchange
Ratio, provided that any fractional share of Buyer Common Stock resulting from
such multiplication shall be rounded down to the nearest share; and (ii) the
exercise price per share of Buyer Common Stock shall be equal to the exercise
price per share of Seller Common Stock of such Seller Option, divided by the
Exchange Ratio, provided that such exercise price shall be rounded up to the
nearest cent.
 
  (b) After the Effective Time, Buyer shall issue to each holder of an
outstanding Seller Option a document evidencing the foregoing assumption of
such Seller Option by Buyer.
 
  (c) It is the intention of the parties that the Seller Options assumed by
Buyer qualify following the Effective Time as incentive stock options as
defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code") to the extent that the Seller Options qualified as incentive stock
options immediately prior to the Effective Time.
 
  (d) Buyer shall not issue or pay for any fractional share otherwise issuable
upon exercise of a Seller Option. Prior to the Effective Time, Buyer shall
reserve for issuance (and, if not previously registered pursuant to the
Securities Act of 1933, as amended (the "Securities Act"), register) the
number of shares of Buyer Common Stock necessary to satisfy Buyer's
obligations with respect to the issuance of Buyer Common Stock pursuant to the
exercise of Seller Options.
 
  (e) The provisions of this Section 2.5 are expressly intended to be for the
irrevocable benefit of, and shall be enforceable by, each holder of a Seller
Option and his or her heirs and representatives.

licensed or qualified to do business and is in good standing in each
jurisdiction in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it makes
such licensing or qualification necessary, except where the failure to be so
licensed, qualified or in good standing would not have a material adverse
effect on Seller and the Seller Subsidiaries.
 
  (b) Seller has previously made available to Buyer for inspection true and
complete copies as amended to date of the (i) Charter and By-laws of Seller
and each of the Seller Subsidiaries, and (ii) all records in the possession of

Seller Common Stock held in its treasury and no Seller Preferred Shares issued

Seller Common Stock have been duly authorized and validly issued and are fully
paid, nonassessable, and free of preemptive rights, with no personal liability
attaching to the ownership thereof. All issued and outstanding shares of each
of the Seller Subsidiaries have been duly authorized and validly issued and
are fully paid, nonassessable, and free of preemptive rights, with no personal
liability attaching to the ownership thereof. All issued and outstanding
shares or interests of each of the Seller Subsidiaries are owned by Seller
free and clear of any security interest, pledge, lien, claim or other
encumbrance or restriction on transfer.
 
  (b) Except for the options to acquire not more than 77,500 shares of Seller
Common Stock pursuant to stock options outstanding as of the date hereof under
the Seller Stock Option Plan, and except for the Seller Common Stock subject
to the Stock Option Agreement with Buyer, neither Seller nor any of the Seller
Subsidiaries has or is bound by any outstanding subscriptions, options,
warrants, calls, commitments or agreements of any character calling for the
transfer, purchase or issuance of, or representing the right to purchase,
subscribe for or otherwise receive, any shares of its capital stock or any

charges taken after such date, are, in the reasonable judgment of Seller based
upon the status of its loan portfolio and general economic conditions as of
the date of this Agreement, adequate to provide for possible losses on loans
outstanding at and as of the date of this Agreement. Subject to such reserve
for possible loan losses, the aggregate principal amount of loans contained in
the loan portfolios of Seller and the Seller Subsidiaries at July 31, 1995,
increased by loans made and reduced by principal payments made after such
date, can reasonably be expected to be collected in the ordinary course of
Seller's operations. The reserves for possible loan losses to be shown on
Seller's consolidated balance sheet included in any Call Report filed with the
FDIC or any Report sent to Seller's stockholders with respect to any period
subsequent to the year ended December 31, 1994 are or will be adequate under
generally accepted accounting principles at and as of the date of each such
balance sheet.
 
  3.28 Loans. Except as set forth on Schedule 3.28 hereto,
 
    (a) All loans reflected as assets in Seller's consolidated balance sheet
  included in the Seller Audited Financial Statements or made or acquired by
  Seller or any of the Seller Subsidiaries since December 31, 1994 ("Loans")
  are binding obligations of the respective obligors named therein and no
  material amount thereof is subject to any defenses which have been or, to
  the best knowledge of Seller, may be asserted against Seller or any of the
  Seller Subsidiaries. Seller has entered into no agreement which would
  result in a waiver or negation of any rights or remedies available against
  the borrower or guarantor, if any, on any such Loan.
 
    (b) All of the real estate mortgage Loans reflected as assets on Seller's
  consolidated balance sheet included in the Seller Audited Financial
  Statements or made or acquired by Seller or any of the Seller Subsidiaries
  since December 31, 1994, were validly and legally made, constitute valid
  and binding agreements of the borrower enforceable in accordance with their
  terms, are secured by properly perfected, valid liens having the priority
  indicated by their terms on the properties described therein. All of such
  mortgage Loans are saleable in the ordinary course of Seller's or any of
  the Seller Subsidiaries' business (which, in the case of commercial
  mortgage Loans, shall mean saleable to a knowledgeable purchaser
  experienced in evaluating such types of obligations). Seller has not
  entered into any agreement which will result in a future waiver or negation
  of any material rights or remedies presently available against the borrower
  or guarantor, if any, on any such Loan. Each mortgage securing a Loan (a
  "Mortgage") has been and is evidenced by documentation of the types
  customarily employed by Seller, which are consistent in all material
  respects with federal and state banking practices and prudent banking
  standards, and complete copies thereof have been maintained by Seller in
  accordance with such standards and practices. Except with respect to
  participation loans described on Schedule 3.28 hereto, Seller and the
  Seller Subsidiaries own and hold the entire interest in all Mortgages free
  and clear of all liens, claims, equities, options, security
 
                                      15
<PAGE>
 
  interests, charges, encumbrances or restrictions of any kind or nature, and
  no person has any interest therein. With respect to any FHA Mortgage, VA
  Mortgage, SBA-guaranteed Loan or other insured or guaranteed instrument,
  the FHA insurance, VA guaranty, SBA guaranty and other insurance or
  guarantees are in full force and effect and neither Seller nor any of the
  Seller Subsidiaries has received any notice of any matter pending or
  threatened which would adversely affect such insurance or guarantee and to
  the best knowledge of Seller, there are no facts or circumstances which
  would provide a basis for any such matter in the future.
 
    (c) Except as disclosed on Schedule 3.28, all Loans were originated in
  compliance with, and comply in all material respects with, all applicable
  laws, rules and regulations, including, but not limited to applicable usury
  statutes, the Truth in Lending Act, the Equal Credit Opportunity Act, the
  Real Estate Settlement Procedures Act, and other applicable consumer
  protection statutes and the regulations thereunder.
 
    (d) Seller has furnished to Buyer a true, correct and complete copy of
  its loan delinquency report as of July 31, 1995 which report includes all
  Loans for which the payment of any installment of principal or interest has
  not been made within 30 days after such installment was due.
 
    (e) All Loans purchased or originated by Seller or any of the Seller
  Subsidiaries and subsequently sold have been sold without recourse to
  Seller or any of the Seller Subsidiaries and without any liability under
  any yield maintenance or similar obligation.
 
    (f) Schedule 3.28 hereto sets forth (x) all of the Loans presently held
  by Seller that prior to the date of this Agreement have been classified
  (whether by any bank examiner or internally) as "Other Loans Specially
  Mentioned," "Special Mention," "Substandard," "Doubtful," "Loss,"
  "Classified," "Criticized," "Credit Risk Assets," "Concerned Loans," "Watch
  List" or words of similar import, together with the principal amount of and
  accrued and unpaid interest on each such Loan and the identity of the
  borrower thereunder, and (y) by category of Loan (i.e., commercial,
  consumer, etc.), all of the other Loans presently held by Seller that prior
  to the date of this Agreement were classified as such, together with the
  aggregate principal amount of and accrued and unpaid interest on such Loans
  by category.
 
  3.29 Transactions with Interested Persons. Except as set forth in Schedule
3.29, neither Seller nor any of the Seller Subsidiaries has any outstanding
loan, deposit or other relationship or other transaction with any officer,
director or stockholder of Seller or any of the Seller Subsidiaries or any
affiliates of any such officer, Director or 5% stockholder (individually, an
"Interested Person"), other than deposit or loan transactions in the ordinary
course of business on terms substantially the same as those prevailing at the
time for comparable transactions with other, unaffiliated persons, and which
did not and do not involve any unusual risk (including of non-collectibility)
or other features unfavorable to Seller or any of the Seller Subsidiaries.
Schedule 3.29 contains a full description of all outstanding loans by Seller
or any of the Seller Subsidiaries to an Interested Person which, individually
or in the aggregate, have current outstanding balances of $50,000 or more
(including in the outstanding balance all amounts which Seller or any of the
Seller Subsidiaries is obligated to advance). All deposit relationships of
Seller or any of the Seller Subsidiaries with an Interested Person with
aggregate balances in excess of $50,000 are fully described on Schedule 3.29.
Except as set forth on Schedule 3.29, neither Seller nor any of the Seller
Subsidiaries has entered into any contractual or other business relationship
with any Interested Person.
 
  3.30 Capital. At June 30, 1995, (a) Seller's Tier 1 risk-based capital ratio
and total risk-based capital ratios were each in excess of applicable limits,
and (b) its leverage ratio was 7.84%, such ratios having been calculated in
accordance with the guidelines of the FDIC on a fully phased-in basis.
 
  3.31 Disclosure. All material facts relating to the business, operations,
results of operations, properties, securities, assets, liabilities and
condition (financial or otherwise) of Seller or the Seller Subsidiaries have
been disclosed to Buyer in this Agreement and the Schedules furnished hereto.
No representation or warranty contained in this Agreement or the Stock Option
Agreement, and no such statement contained in any Schedule, certificate, list
or letter furnished to Buyer pursuant to the provisions hereof or thereof,
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements herein or therein not
misleading.

FDIC. Each of Buyer and the Buyer Subsidiaries has the power and authority to
own or lease all of its properties and assets and to conduct its business as
it is now being conducted, and is duly licensed or qualified to do business
and is in good standing in each jurisdiction in which the nature of the
business conducted by it or the character or location of the properties and
assets owned or leased by it makes such licensing or qualification necessary,
except where the failure to be so licensed, qualified or in good standing
would not have a material adverse effect on Buyer and the Buyer Subsidiaries.
Buyer is registered as a bank holding company with the Federal Reserve under
the Bank Holding Company Act of 1956, as amended.
 
  (b) Buyer has previously made available to Seller for inspection true and
complete copies as amended to date of the (i) Charter and By-laws of Buyer and

Buyer of all meetings and other corporate action taken by the stockholders,
Board of Directors and committees thereof, of Buyer and each of the Buyer
Subsidiaries. The minute books of Buyer and each of the Buyer Subsidiaries
contain records, which are complete and accurate in all material respects, of
incorporators, shareholders, directors, committees and stockholders, as the
case may be, and all meetings and actions reflected therein have been duly and
validly held or taken within the past ten years.
 
  (c) Neither Buyer nor any of the Buyer Subsidiaries owns, controls or holds
with the power to vote, directly or indirectly of record, beneficially or
otherwise, any capital stock or any equity or ownership interest in any

personal liability attaching to the ownership thereof. The shares of Buyer
Common Stock to be issued pursuant to the Merger will be duly authorized and
validly issued and (at the Effective Time) will be fully paid, nonassessable,
and free of preemptive rights, with no personal liability attaching to the
ownership thereof. All issued and outstanding shares or interests of each of
the Buyer Subsidiaries are owned by Buyer free and clear of any security
interest, pledge, lien, claim or other encumbrance or restriction on transfer.

Proxy Statement-Prospectus to its respective stockholders. Buyer shall also
use its best efforts to obtain all necessary state securities law or "Blue
Sky" permits and approvals required to carry out the transactions contemplated
by this Agreement, and Seller shall furnish all information concerning Seller
and the holders of Seller Common Stock as may be reasonably requested in
connection with any such action. Seller and Buyer shall each promptly notify
the other if at any time it becomes aware that the Proxy Statement-Prospectus
contains any untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements
contained therein, in light of the circumstances under which they were made,
not misleading. In such event, Seller and Buyer shall cooperate in the
preparation of a supplement or amendment to the Proxy Statement-Prospectus,
which corrects such misstatement or omission, and shall cause the same to be
filed with the FDIC and the SEC and distributed to stockholders of Seller.
 
  7.2 Regulatory Approvals. Each of Seller and Buyer will cooperate with the
other and use all reasonable efforts to prepare and execute all necessary
documentation (including, without limitation, a Contract for Union in a form
reasonably acceptable to Seller and Buyer), to promptly effect all necessary
filings and to obtain all necessary permits, consents, approvals and
authorizations of all third parties and governmental bodies necessary to
consummate the transactions contemplated by this Agreement and the Stock
Option Agreement. Seller and Buyer will furnish each other and each other's
counsel with all information concerning themselves, their subsidiaries,
directors, officers and stockholders and such other matters as may be
necessary or advisable in connection with the Proxy Statement-Prospectus and
any application, petition or any other statement or application made by or on
behalf of Seller or Buyer to any governmental body in connection with the
Merger and the other transactions contemplated by this Agreement. Seller and
Buyer shall have the right to review and approve in advance all
characterizations of the information relating to Buyer or Seller, as the case
may be, and
 
                                      29
<PAGE>
 
any of their respective subsidiaries, which appear in any filing made in
connection with the transactions contemplated by this Agreement with any
governmental body. In addition, Seller and Buyer shall each furnish to the
other a final copy of each such filing made in connection with the
transactions contemplated by this Agreement with any governmental body.
 
  7.3 Affiliates; Publication of Combined Financial Results. Each of Buyer and
Seller shall use all reasonable efforts to cause each director, executive
officer and other person who is an "affiliate" (for purposes of Rule 145 under
the Securities Act and for purposes of qualifying the Merger for "pooling-of-
interests" accounting treatment) of such party to deliver to the other party
hereto, as soon as practicable after the date of this Agreement, and prior to
the date of the shareholders meeting called by Seller to approve this
Agreement, a written agreement, in the form of Exhibit 7.3 hereto, providing
that such person will not sell, pledge, transfer or otherwise dispose of any
shares of Buyer Common Stock or Seller Common Stock held by such "affiliate",
and, in the case of the "affiliates" of Seller, the shares of Buyer Common
Stock to be received by such "affiliate" in the Merger: (1) otherwise than in
compliance with the applicable provisions of the Securities Act and the rules
and regulations thereunder or (2) during the period commencing 30 days prior
to the Merger and ending at the time of the publication of financial results
covering at least 30 days of combined operations of Buyer and Seller. Such
agreement shall also contain such representations as are necessary or
appropriate to support the tax-free nature of the Merger.
 
  7.4 Agreement to Vote in Favor of Merger. Seller has caused each director
and certain of their related interests to grant to Buyer an irrevocable proxy
in the form attached hereto as Exhibit 7.4. Such proxy shall grant to Buyer
the authority (x) to call a special meeting of stockholders of Seller to
approve the Merger, this Agreement and the transactions contemplated hereby
and (y) to vote, in any manner that Buyer may determine in its sole and
absolute discretion to be in the best interest of Buyer, all of the shares of
Seller Common Stock as to which each such person has voting power at any
meeting of stockholders of Seller on matters in any way relating to the
Merger, the Merger Agreement, and the transactions contemplated thereby.

                              Closing Conditions
 
  8.1 Conditions to Each Party's Obligations under this Agreement. The
respective obligations of each party under this Agreement shall be subject to
the fulfillment at or prior to the Effective Time of the following conditions,
none of which may be waived:
 
    (a) Stockholder Approval. This Agreement and the transactions
  contemplated hereby shall have been approved in accordance with applicable
  law by the requisite votes of the stockholders of Seller and of Buyer.
 
    (b) Injunctions; Illegality. No order, decree or injunction of a court or
  agency of competent jurisdiction or other legal restraint or prohibition
  (an "Injunction") preventing the consummation of the Merger, or any of the
  other transactions contemplated by this Agreement, shall be in effect and
  no proceeding initiated by a third party including, without limitation, any
  Governmental Entity, seeking an Injunction, shall be pending; provided,
  however, that, with respect to any such pending matter, counsel to the
  party seeking to postpone the Closing of the transactions contemplated
  hereby or terminate this Agreement has advised such party that such pending
  matter may reasonably be expected to have a material adverse effect on the
  other party. No statute, rule, regulation, order, injunction or decree
  shall have been enacted, entered, promulgated or enforced by any
  Governmental Entity which prohibits, restricts or makes illegal
  consummation of the Merger, or any of the other transactions contemplated
  by this Agreement.
 
    (c) Regulatory Approvals. All necessary approvals, authorizations and
  consents of all governmental bodies required to consummate the Merger and
  the other transactions contemplated by this Agreement shall have been
  obtained and shall remain in full force and effect and all waiting periods
  relating to such approvals, authorizations or consents shall have expired.
 
                                      30
<PAGE>
 
    (d) Effectiveness of Registration Statement. The Registration Statement
  shall have become effective under the Securities Act and no stop order
  suspending the effectiveness of the Registration Statement shall have been
  issued, and no proceedings for that purpose shall have been initiated or
  threatened by the SEC.
 
    (e) Tax Rulings or Opinions. Each of Buyer and Seller shall have received
  an opinion of counsel reasonably acceptable to Buyer and Seller, addressed
  to Buyer and the shareholders of Seller, with respect to federal tax laws
  or regulations, to the effect that:
 
      (1) The merger will constitute a reorganization within the meaning of
    Section 368(a)(1) of the Code;
 
      (2) No gain or loss will be recognized by Buyer, Seller or Buyer Sub
    or Surviving Bank by reason of the Merger;
 
      (3) The bases of the assets of Seller in the hands of the Surviving
    Bank will be the same as the bases of such assets in the hands of
    Seller immediately prior to the Merger;
 
      (4) The holding period of the assets of Seller in the hands of the
    Surviving Bank will include the period during which such assets were
    held by Seller prior to the Merger;
 
      (5) No gain or loss will be recognized by the Seller shareholders on
    the exchange of shares of Seller Common Stock solely for shares of
    Buyer Common Stock; income gain or loss will be recognized, however, to
    each such shareholder upon the receipt of cash by such shareholders on
    the exchange. The determination of whether the receipt of cash by
    Seller shareholders will have the effect of the distribution of a
    dividend will be made by treating the shareholder as having received
    solely shares of Buyer Common Stock in the reorganization exchange and
    then having received the cash payment from Buyer in a hypothetical
    redemption of that number of shares of Buyer Common Stock equal in
    value to such cash payment.
 
      (6) The basis of the shares of Buyer Common Stock to be received by
    Seller shareholders will be the same as the basis of the shares of
    Seller's Common Stock surrendered in the reorganization exchange,
    decreased by the amount of cash received and increased by the amount of
    any gain (and by the amount of any dividend income) recognized on the
    exchange.
 
      (7) The holding period of the shares of Buyer Common Stock to be
    received by the shareholders of Seller will include the period during
    which they held the shares of Seller's Common Stock surrendered,
    provided the shares of Seller's Common Stock are held as a capital
    asset on the date of the exchange.
 
  8.2 Conditions to the Obligations of Buyer under this Agreement. The
obligations of Buyer under this Agreement shall be further subject to the
satisfaction, at or prior to the Effective Time, of the following conditions:
 
    (a) Representations and Warranties. Each of the representations and
  warranties of Seller in this Agreement which is qualified as to materiality
  shall be true and correct and each such representation or warranty that is
  not so qualified shall be true and correct in all material respects, in
  each case as of the date of this Agreement, as applicable, and (except to
  the extent such representations and warranties speak as of an earlier date)
  as of the Effective Time. Seller shall have delivered to Buyer a
  certificate of Seller to such effect signed by the Chief Executive Officer
  and the Chief Financial Officer of Seller as of the Effective Time.
 
    (b) Material Adverse Change. There shall have occurred no material
  adverse change in the business, operations, results of operations,
  properties, assets, liabilities, securities, capitalization or condition
  (financial or otherwise) of Seller or any Seller Subsidiaries since the
  date of the consolidated financial statements contained in the Seller
  Audited Financial Statements. The fact that the conditions set forth in
  Sections 8.2(c) and (d) hereof have been satisfied shall not preclude the
  existence of any material adverse change that may otherwise exist for
  purposes of this Section 8.2(b).
 
                                      31
<PAGE>
 
    (c) Non-Performing Assets. As of the last day of any fiscal quarter of
  Seller following the date hereof, or as of any date following satisfaction
  of the condition set forth in Section 8.1(c) and prior to the Effective
  Time, the aggregate balance of Seller's Non-Performing Assets (determined
  in accordance with regulatory requirements) shall not exceed 2% of Seller's
  aggregate balance of Loans and Non-Performing Assets. The term Non-
  Performing Assets, as of any date, shall include (A) all Loans with respect
  to which, as of the close of business on such date, any payment of interest
  or principal that was due more than 90 days before such date has not been
  made, (B) all Loans classified as "in substance foreclosure", (C) the
  carrying value of all other real estate owned by Seller (other than bank
  premises), (D) all Loans (other than Loans included pursuant to (A), (B) or
  (C) above) which Seller has classified as non-accruing for any other
  reason, and (E) all Loans that are the subject of troubled debt
  restructurings, as defined in Statement of Financial Accounting Standards
  15.
 
    (d) Minimum Increase in Net Worth. As of the last day of any fiscal
  quarter of Seller following the date hereof, and as of any date following
  satisfaction of the conditions set forth in Section 8.1(c) and prior to the
  Effective Time, the consolidated net worth of Seller ("Seller Net Worth")
  shall have increased by at least $100,000 during each calendar quarter
  (beginning with the calendar quarter ended March 31, 1995) from its
  consolidated net worth as of December 31, 1994. All calculations of Seller
  Net Worth shall be in accordance with GAAP, except that (1) the base Seller
  Net Worth as of December 31, 1994, shall be based upon the consolidated net
  worth set forth on the balance sheet contained in the 1994 Seller Audited
  Financial Statements but shall be restated to eliminate the effects of any
  adjustments to such consolidated net worth made to reflect the changes in
  the value of securities pursuant FASB 115; (2) all determinations of Seller
  Net Worth shall be calculated so as to eliminate the effects of any
  adjustments made to such consolidated net worth in order to reflect the
  changes in value of securities pursuant FASB 115; (3) the amounts of any
  gains upon sales of securities or capital assets shall not be included in
  determination of Seller Net Worth; and (4) the expenses reasonably incurred
  by Seller in connection with the Merger shall not be deducted in making
  such calculations.
 
    (e) Agreements and Covenants. Seller shall have performed in all material
  respects all obligations and complied in all material respects with all
  agreements or covenants of Seller to be performed or complied with by it at
  or prior to the Effective Time under this Agreement and Buyer shall have
  received a certificate signed on behalf of Seller by the Chief Executive
  Officer and Chief Financial Officer of Seller to such effect dated as of
  the Effective Time.
 
    (f) Permits, Authorizations, Etc. Seller and the Seller Subsidiaries
  shall have obtained any and all material permits, authorizations, consents,
  waivers, clearances or approvals required for the lawful consummation of
  the Merger by Seller.
 
    (g) Legal Opinion. Buyer shall have received an opinion, dated the
  Closing Date, from McLane, Graf, Raulerson & Middleton, PA, counsel to
  Seller, acceptable in form and substance to Buyer and its counsel. In
  rendering any such opinion, such counsel may require and, to the extent
  they deem necessary or appropriate may rely upon, opinions of other counsel
  and upon representations made in certificates of officers of Seller, Buyer,
  Affiliates of the foregoing, and others.
 
    (h) Pooling of Interests. Buyer shall have received a letter from KPMG
  Peat Marwick LLP, addressed to Buyer, to the effect that the Merger will
  qualify for "pooling of interests" accounting treatment.
 
    (i) Dissenting Seller Shareholders. The holders of not more than 8% of
  the Seller Common Stock outstanding immediately prior to the Effective Time
  shall have given notice of their intention to exercise dissenters' rights
  pursuant to the NHRSA.
 
    (j) Accountants' Letter. Buyer shall have received a "comfort" letter
  from the independent certified public accountants for Seller, dated (i) the
  effective date of the Registration Statement and (ii) the Closing Date, in
  each case stating:
 
      (1) that it is a firm of independent public accountants with respect
    to Seller and its subsidiaries within the meaning of the Securities Act
    and the rules and regulations of the SEC thereunder;
 
                                      32
<PAGE>
 
      (2) that in its opinion the audited consolidated financial statements
    of Seller and its subsidiaries examined by it and included in the
    Registration Statement comply as to form in all material respects with
    the applicable requirements of the Securities Act and the applicable
    published rules and regulations of the SEC thereunder with respect to
    registration statements on the form employed;
 
      (3) that, on the basis of specified procedures (which do not
    constitute an examination in accordance with generally accepted
    auditing standards), consisting of a reading of the unaudited
    consolidated financial statements, if any, of Seller included in such
    Registration Statement and of the latest available unaudited
    consolidated financial statements of Seller, inquiries of officers
    responsible for financial and accounting matters of Seller and its
    subsidiaries and a reading of the minutes of meetings of shareholders
    and the Board of Directors of Seller and its subsidiaries, nothing has
    come to its attention which causes it to believe: (i) that the
    consolidated financial statements, if any, of Seller included in such
    Registration Statement do not comply in all material respects with the
    applicable accounting requirements of the Securities Act and the
    published rules and regulations thereunder; and (ii) that any such
    unaudited consolidated financial statements of Seller from which
    unaudited quarterly financial information set forth in such
    Registration Statement has been derived, are not fairly presented in
    conformity with generally accepted accounting principles applied on a
    basis consistent with that of the audited consolidated financial
    statements; and
 
      (4) Whether, from the date of the latest available unaudited
    consolidated financial statements of Seller through the date of the
    letter, there were any changes in financial statement amounts, such
    financial statement amounts being those customarily appearing in
    comfort letters.
 
    (k) Fairness Opinion. Buyer shall have received a letter from MBD, dated
  as of a date not more than five (5) days prior to the date the Proxy
  Statement-Prospectus contemplated by Section 7.1 is mailed to stockholders,
  confirming its oral opinion, delivered prior to the date of this Agreement,
  that the consideration to be paid to Seller's stockholders pursuant to the
  Merger is fair to Buyer and its stockholders, from a financial point of
  view.
 
  Seller will furnish Buyer with such certificates of its officers or others
and such other documents to evidence fulfillment of the conditions set forth
in this Section 8.2 as Buyer may reasonably request.
 
  8.3 Conditions to the Obligations of Seller under this Agreement. The
obligations of Seller under this Agreement shall be further subject to the
satisfaction, at or prior to the Effective Time, of the following conditions:
 
    (a) Representations and Warranties. Each of the representations and
  warranties of Buyer in this Agreement which is qualified as to materiality
  shall be true and correct and each such representation or warranty that is
  not so qualified shall be true and correct in all material respects, in
  each case as of the date of this Agreement, as applicable, and (except to
  the extent such representations and warranties speak as of an earlier date)
  as of the Effective Time. Buyer shall have delivered to Seller a
  certificate of Buyer to such effect signed by the Chief Executive Officer
  and the Chief Financial Officer of Buyer as of the Effective Time.
 
    (b) Material Adverse Change. There shall have occurred no material
  adverse change in the business, operations, results of operations,
  properties, assets, liabilities, securities, capitalization or condition
  (financial or otherwise) of Buyer and the Buyer Subsidiaries, taken as a
  whole, since the date of the consolidated financial statements contained in
  the Buyer Audited Financial Statements, including, without limiting the
  generality of the foregoing, a decline in the market price of the Buyer's
  Common Stock so that the Average Closing Price is less than 75% of Buyer's
  Book Value Per Share. Any change in the stock price, results of operations,
  capitalization, or financial condition of Buyer that results from (i) a
  change in law affecting savings banks generally, such as a change in the
  tax deduction for bad debt reserves applicable to savings banks, or (ii) a
  purchase of deposits or retail branches in connection with the
  Fleet/Shawmut merger, shall be deemed not to constitute or contribute to a
  material adverse change.
 
                                      33
<PAGE>
 
    (c) Agreements and Covenants. Buyer shall have performed in all material
  respects all obligations and complied in all material respects with all
  agreements or covenants of Buyer to be performed or complied with by it at

  received a certificate signed on behalf of Buyer by the Chief Executive
  Officer and Chief Financial Officer of Buyer to such effect dated as of the
  Effective Time.
 
    (d) Permits, Authorizations, Etc. Buyer and its subsidiaries shall have
  obtained any and all material permits, authorizations, consents, waivers,
  clearances or approvals required for the lawful consummation of the Merger
  by Buyer, the failure to obtain which would have a material adverse effect
  on Buyer and its subsidiaries, taken as a whole.
 
    (e) Legal Opinion. Seller shall have received an opinion from Foley, Hoag
  & Eliot, counsel to Buyer, dated the Closing Date, acceptable in form and
  substance to Seller and its counsel. In rendering any such opinion, such
  counsel may require and, to the extent they deem necessary or appropriate
  may rely upon, opinions of other counsel and upon representations made in
  certificates of officers of Buyer, Seller, Affiliates of the foregoing, and
  others.
 
    (f) Fairness Opinion. Seller shall have received a letter from its
  investment advisor, dated as of a date not more than five (5) days prior to
  the date the Proxy Statement-Prospectus contemplated by Section 7.1 is
  mailed to stockholders, confirming its oral opinion, delivered prior to the
  date of this Agreement, that the consideration to be paid to Seller's
  stockholders pursuant to the Merger is fair to such stockholders, from a
  financial point of view.
 
  Buyer will furnish Seller with such certificates of its officers or others
and such other documents to evidence fulfillment of the conditions set forth
in this Section 8.3 as Seller may reasonably request.

  this Agreement (the "Termination Date"), or such later date as shall have
  been agreed to in writing by Buyer and Seller; provided, that no party may
  terminate this Agreement pursuant to this Section 10.1(c) if the failure of

  breach of any of its obligations under this Agreement;
 
    (d) By either Seller or Buyer if the stockholders of Seller or Buyer
  shall have voted at the Special Meeting on the transactions contemplated by
  this Agreement and such vote shall not have been sufficient to approve such
  transactions; or
 
    (e) By either Seller or Buyer if final action has been taken by a
  regulatory authority whose approval is required in connection with this

    expense on the part of any party to the other; and
 
      (2) In the event of a termination of this Agreement pursuant to
    Section 10.1(b) hereof as a result of a breach of a representation,
    warranty or covenant which is caused by the wilful conduct or gross

    liabilities or damages arising out of such wilful breach or gross
    negligence) be obligated to reimburse the other party for all out-of-
    pocket costs and expenses, including, without limitation, reasonable
    legal, accounting and investment banking fees and expenses, incurred by
    such other party in connection with the entering into of this Agreement
    and the carrying out of any and all acts contemplated hereunder
    (collectively referred to as "Expenses"), provided that in no event

    (c) The payment of Expenses is not an exclusive remedy, but is in
  addition to any other rights or remedies available to the parties hereto at
  law or in equity and notwithstanding anything to the contrary contained
  herein, no party shall be relieved or released from any liabilities or
  damages arising out of its gross negligence or wilful breach of any

<PAGE>
 
Agreement may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto; provided, however, that (i) after any
approval of this Agreement and the transactions contemplated hereby by the
stockholders of Seller, there may not be, without further approval of such
stockholders, any amendment or waiver of this Agreement which decreases the
amount or changes the form of consideration to be delivered to Seller's
stockholders pursuant to this Agreement, and (ii) after any approval of this
Agreement and the transactions contemplated hereby by the stockholders of
Buyer, there may not be, without further approval of such stockholders, any
amendment or waiver of this Agreement which increases the amount or changes
the form of consideration to be delivered to Seller's stockholders pursuant to
this Agreement. Any agreement on the part of a party hereto to any extension
or waiver shall be valid only if set forth in an instrument in writing signed
on behalf of such party, but such waiver or failure to insist on strict
compliance with such obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

                            STOCK OPTION AGREEMENT
 
  This Stock Option Agreement (the "Agreement") is entered into as of August
 , 1995 by and between Community Bankshares, Inc., a New Hampshire bank
holding company ("Community") and Centerpoint Bank, a New Hampshire trust
company ("Centerpoint").
 
  Whereas, Centerpoint and Community propose to enter into an Agreement and
Plan of Merger dated as of the date hereof (the "Merger Agreement";
capitalized terms not defined herein shall have the meanings set forth in the
Merger Agreement), providing for, among other things, the combination and
merger of a newly-formed bank subsidiary of Community and Centerpoint into a
single bank, which will be a subsidiary of Community; and
 
  Whereas, as a condition and an inducement to Community's willingness to
enter into the Merger Agreement, Community has requested that Centerpoint
agree, and Centerpoint has agreed, to grant Community the Option (as defined
below);
 
  Now, Therefore, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth herein and in
the Merger Agreement, Centerpoint and Community agree as follows:
 
  1. Grant of Option. Subject to the terms and conditions set forth herein,
Centerpoint hereby grants to Community an irrevocable option (the "Option") to
acquire up to 165,920 shares (the "Option Shares") of common stock, par value
$1.00 per share, of Centerpoint ("Centerpoint Common Stock") at an acquisition
price of $12.00 per Option Share (the "Purchase Price"). The number of shares
of Centerpoint Common Stock that may be received upon the exercise of the
Option and the Purchase Price are subject to adjustment as herein set forth.
 
  2. Certain Definitions. (a) The holder or holders of this Option ("Holder")
may exercise the Option, in whole or in part, at any time and from time to
time following the occurrence of a Triggering Event (as defined below). Except
as otherwise provided in this Agreement, the right to exercise the Option
shall expire and be of no further force and effect upon the occurrence of a
Termination Event (as defined below).
 
  (b) Each of the following shall constitute a "Termination Event":
 
    (i) the Effective Time;
 
    (ii) the first anniversary of a Triggering Event;
 
    (iii) the second anniversary of a termination of the Merger Agreement by
  reason of a material breach or wilful violation by Centerpoint of its
  representations, warranties or obligations under the Merger Agreement,
  provided, however, that such anniversary shall be a Termination Event only
  if such anniversary occurs prior to the occurrence of a Triggering Event;
 
    (iv) immediately (A) upon termination of the Merger Agreement by
  Centerpoint by reason of a breach or violation by Community of its
  representations, warranties or obligations under the Merger Agreement, or
  (B) if the holders of Community Common Stock shall not have approved the
  Merger Agreement and the transactions contemplated thereby at the Community
  Special Meeting held for the purpose of voting on the Merger Agreement; or
 
 
                                      42
<PAGE>
 
    (v) the second anniversary of a termination of the Merger Agreement other
  than as described in Section 2(b)(iii) or Section 2(b)(iv), provided,
  however, that such anniversary shall be a Termination Event only if such
  anniversary occurs prior to the occurrence of a Triggering Event.
 
  (c) Notwithstanding any expiration or termination of the Option, Community
shall be entitled to acquire those Option Shares with respect to which it has
exercised the Option in accordance with the terms hereof prior to the
expiration or termination of the Option. Any purchase of shares upon exercise
of the Option shall be subject to compliance with requirements established by
the New Hampshire Board of Trust Company Incorporation and with all other
requirements of applicable law, including the Bank Holding Company Act of
1956, as amended (the "BHC Act").
 
  (d) A "Triggering Event" shall occur for purposes of this Agreement upon the
occurrence of any of the following:
 
    (i) without having received Community's prior written consent,
  Centerpoint shall have entered into, or the Board of Directors of

  Centerpoint approve or accept, an agreement with any person (other than
  Community or any affiliate of Community) to (A) effect a merger,
  consolidation or similar transaction involving Centerpoint, (B) sell, lease
  or otherwise dispose of assets of Centerpoint (other than sales of loans or
  securities classified as available for sale in the ordinary course of
  business of Centerpoint) representing 15% or more of the consolidated
  assets of Centerpoint, or (C) issue, sell or otherwise dispose of
  (including by way of merger, consolidation, share exchange or any similar
  transaction) securities representing 15% or more of the voting power of
  Centerpoint (any of the foregoing an "Acquisition Transaction");
 
    (ii) any person (other than Community or any affiliate of Community)
  shall, after the date hereof, have acquired beneficial ownership (as
  defined in Rule 13(d)-3 under the Securities Exchange Act of 1934, as
  amended (the "Exchange Act")), or the right to acquire beneficial ownership
  of, or any "group" (as such term is defined under the Exchange Act) shall
  have been formed which beneficially owns or has the right to acquire
  beneficial ownership of, 15% or more of the then outstanding Centerpoint
  Common Stock;
 
    (iii) any person (other than Community or any affiliate of Community) (1)

  or modified in a manner adverse to Community its recommendation with
  respect to the Merger Agreement; or
 
    (v) the holders of Centerpoint Common Stock shall not have approved the
  Merger Agreement and the transactions contemplated thereby at the Special
  Meeting held for the purpose of voting on the Merger Agreement or such
  Special Meeting shall not, due to actions or failure to act of Centerpoint,
  have been held prior to a date which is 60 days ("End Date") after
  effectiveness of the Registration Statement on Form S-4, provided, however,
  that the events described in this Section 2(d)(v) shall constitute a
  Triggering Event only if, prior to the End Date, Centerpoint shall have
  agreed to provide to a stockholder or a stockholder representative a copy
  of its list of Centerpoint stockholders for use in connection with possible
  communications with other Centerpoint stockholders.
 
As used in this Agreement, "person" shall have the meaning specified in
Sections 3(a)(9) and 13(d)(3) of the Exchange Act and includes any individual,
corporation, partnership, company, group or other entity. Terms defined herein
by reference to the Exchange Act shall be construed as if Centerpoint had

place and date not earlier than three business days nor later than 15 business
days from the Notice Date for the closing of such acquisition (the "Closing

  (b) If the closing of the acquisition pursuant to the exercise of the Option
(the "Closing") cannot be consummated by reason of any judgment, decree or
order, the period of time that otherwise would run pursuant to Section 3(a)
shall run instead until the date on which such judgment, decree or order
becomes final and nonappealable. Without limiting the foregoing, if prior
notification to or approval of the Board of Governors of the Federal Reserve
System ("FRB") or an other regulatory authority is required in connection with
such purchase, Community shall promptly file the required notice or
application for approval and shall expeditiously process the same (and
Centerpoint shall cooperate with Community in the filing of any such notice or
application and the obtaining of any such approval), and the period of time
that otherwise would run pursuant to Section 3(a) shall run instead from the

Date.
 
  (b) At each Closing, simultaneously with the delivery of the consideration
specified in Section 4(a), Centerpoint shall deliver to Community a
certificate or certificates representing the Option Shares to be acquired at
such Closing, which Option Shares shall be free and clear of all liens,
claims, charges and encumbrances of any kind whatsoever (including any
preemptive rights of any stockholder).

  assets; or
 
    (ii) any person (other than Community or any affiliate of Community)
  shall, after the date hereof, have acquired beneficial ownership (as
  defined in Rule 13(d)-3 under the Exchange Act) or the right to acquire
  beneficial ownership of, or any "group" (as such term is defined under the
  Exchange Act) shall have been formed which beneficially owns or has the
  right to acquire beneficial ownership of, 51% or more of the then
  outstanding Centerpoint Common Stock.
 
  (b) Section 8 Repurchase Consideration. At the request of Community at any
time commencing upon the occurrence of a Repurchase Event and ending upon the
earlier to occur of (x) 9 months immediately thereafter or (y) a Termination
Event, Centerpoint (or any successor entity thereof) shall repurchase from
Community (1) the Option (unless the Option shall have expired or been
terminated in accordance with the terms hereof) and (2) all shares of
Centerpoint Common Stock purchased by Community pursuant hereto with respect
to which Community then has beneficial ownership. The date on which Community
exercises its rights under this Section 8 is referred to as the "Request
Date". Such repurchase shall be at an aggregate price (the "Section 8
Repurchase Consideration") equal to the sum of:
 
    (i) the aggregate exercise price paid by Community for any shares of
  Centerpoint Common Stock acquired pursuant to the Option with respect to
  which Community then has beneficial ownership;
 
    (ii) the excess, if any, of (x) the Applicable Price (as defined below)
  for each share of Centerpoint Common Stock over (y) the Purchase Price
  (subject to adjustment pursuant to Section 7), multiplied by the number of
  shares of Centerpoint Common Stock with respect to which the Option has not
  been exercised; and
 
    (iii) the excess, if any, of the Applicable Price over the Purchase Price
  (subject to adjustment pursuant to Section 7) paid (or, in the case of
  Option Shares with respect to which the Option has been exercised but the
  Closing Date has not occurred, payable) by Community for each share of
  Centerpoint Common Stock with respect to which the Option has been
  exercised and with respect to which Community then has beneficial
  ownership, multiplied by the number of such shares.
 
  (c) If Community exercises its rights under this Section 8, Centerpoint
shall, within 10 business days after the Request Date, pay the Section 8
Repurchase Consideration to Community in immediately available funds, and
Community shall surrender to Centerpoint the Option and the certificates
evidencing the shares of
 
                                      46
<PAGE>
 
Centerpoint Common Stock purchased thereunder with respect to which Community
then has beneficial ownership; and Community 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 the FRB or other Governmental Entity is
required in connection with the payment of all or any portion of the Section 8
Repurchase Consideration or is not then permissible under applicable law,
Centerpoint shall deliver from time to time that portion of the Section 8
Repurchase Consideration that it is not then so prohibited from paying and
shall promptly file the required notice or application for approval and shall
expeditiously process the same (and Community shall cooperate with Centerpoint
in the filing of any such notice or application and the obtaining of any such
approval), and the period of time that otherwise would run pursuant to the
preceding sentence for the payment of the portion of the Section 8 Repurchase
Consideration requiring such notification or approval shall run instead from
the date on which, as the case may be, (i) any required notification period
has expired or been terminated or (ii) such approval has been obtained and, in
either event, any requisite waiting period shall have passed. If the FRB or
any other Governmental Entity disapproves of any part of Centerpoint's
proposed repurchase pursuant to this Section 8, Centerpoint shall promptly
give notice of such fact to Community and redeliver to Community the Option
Shares it has acquired from Community pursuant hereto and is then prohibited
from repurchasing, and Community shall 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 number of shares as to which payment has been made
pursuant to Section 8(b); provided that if the Option shall have expired prior
to the date of such notice or shall be scheduled to expire at any time before
the expiration of a period ending on the thirtieth business day after such
date, Community shall nonetheless have the right so to exercise the Option
until the expiration of such period of 30 business days. Notwithstanding
anything herein to the contrary, Centerpoint shall not be obligated to
repurchase the Option or any shares of Centerpoint Common Stock pursuant to
this Section 8 on more than one occasion.
 
  (d) For purposes of this Agreement, the "Applicable Price" means the highest
of (i) the highest price per share at which a tender or exchange offer has
been made for shares of Centerpoint Common Stock after the date hereof and on
or prior to the Request Date, (ii) the price per share to be paid by any third
party for shares of Centerpoint Common Stock or the consideration per share to
be received by holders of Centerpoint Common Stock, in each case pursuant to
an agreement for a merger or other business combination transaction with
Centerpoint entered into on or prior to the Request Date or (iii) the highest
bid price per share as quoted on the principal trading market on which such
shares are traded as reported by a recognized source during the 60 business
days preceding the Request Date. 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 Community and reasonably acceptable to Centerpoint, which
determination shall be conclusive for all purposes of this Agreement.
 
  9. REPURCHASE AT THE OPTION OF CENTERPOINT.
 
  (a) Except to the extent that Community shall have previously exercised its
rights under Section 8, at the request of Centerpoint during the 30-day period
commencing 12 months following the first occurrence of a Repurchase Event,
Centerpoint may repurchase from Community, and Community shall sell to
Centerpoint, all (but not less than all) of the shares of Centerpoint Common
Stock acquired by Community pursuant hereto and with respect to which
Community has beneficial ownership at the time of such repurchase at a price
equal to the greater of (A) 110% of the Current Market Price (as defined
below) or (B) the sum of (1) the Purchase Price in respect of the shares so
acquired plus (2) Community's pre-tax per share carrying cost (as defined
below), multiplied in either case by the number of shares so acquired (the
"Section 9 Repurchase Consideration"); provided that Centerpoint's rights
under this Section 9 shall be suspended (with any such rights being extended
accordingly) during any period when the exercise of such rights would subject
Community to liability pursuant to Section 16(b) of the Exchange Act by reason
of Community's purchase of shares of Centerpoint Common Stock hereunder.
 
                                      47
<PAGE>
 
  (b) If Centerpoint exercises its rights under this Section 9 and Community
does not sell the shares to a third party pursuant thereto, Centerpoint shall,
within 10 business days after the expiration of the 30-day period referred to
in paragraph (a) above or, if applicable, upon abandonment of the transaction
covered by the Offeror's Notice, pay the Section 9 Repurchase Consideration in
immediately available funds, and Community shall surrender to Centerpoint the
certificates evidencing the shares of Centerpoint Common Stock purchased
hereunder with respect to which Community then has beneficial ownership, and
Community 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.
 
  (c) As used herein, (i) "Current Market Price" means the average closing
sales price per share of Centerpoint Common Stock quoted on the principal
trading market on which such shares are traded as reported by a recognized
source for the 10 business days preceding the date of Centerpoint's request
for repurchase pursuant to this Section 9 and (ii) "Community's pre-tax per
share carrying cost" shall be the amount equal to the interest on the
aggregate Purchase Price paid for the shares of Centerpoint Common Stock
purchased from the date of purchase to the date of repurchase at the rate of
interest announced by Bank of Boston as its prime or base lending or reference
rate during such period, less any dividends received on the shares so
purchased, divided by the number of shares so purchased.
 
  10. Division of Option. This Agreement and the Option granted hereby are
exchangeable, without expense, at the option of Community upon partial
exercise of the Option or partial assignment of the Option, in both instances
as provided herein, upon presentation and surrender of this Agreement at the
principal office of Centerpoint, for other Agreements providing for Options of
different denominations entitling the holder thereof to acquire in the
aggregate the same number of shares of Centerpoint Common Stock which may be
acquired hereunder. The terms "Agreement" and "Option" as used herein include
any other Agreements and related Options for which this Agreement and the
Option granted hereby may be exchanged.
 
  11. Miscellaneous.

the parties hereto shall bear and pay all costs and expenses incurred by it or
on its behalf in connection with the transactions contemplated hereunder,
including fees and expenses of its own counsel.

any time by the party that is entitled to the benefits of such provision. This

hereto.

otherwise set forth in the Merger Agreement, this Agreement (including other
documents and instruments referred to herein or therein) (i) constitutes the
entire agreement and supersedes all prior agreements and understandings, both
written and oral, between the parties with respect to the subject matter
hereof and (ii) is not intended to confer upon any person other than the
parties hereto any rights or remedies hereunder. If any term, provision,
covenant or restriction of this Agreement is held by a court of competent
jurisdiction or a regulatory agency to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated.
 
  (d) Governing Law. This Agreement shall be governed by the internal laws of
New Hampshire without regard its conflicts of law principles.

parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other party, except that: (i) Community may assign this
Agreement to any subsidiary or affiliate, and (ii) after the occurrence of a
Repurchase Event Community may assign its rights under this Agreement to third
parties; provided, however, that until the date 30 days following the date on
which the Federal Reserve Board approves an application by Community under the
BHC Act to acquire the shares of Centerpoint Common Stock subject to the
Option, Community may not assign its rights under the Option except in a
manner approved by the Federal Reserve Board, and provided, further, that,
notwithstanding any such assignment, Community shall continue to be liable for
the performance of its obligations under this Agreement. Subject to the
preceding sentence, this Agreement shall be binding upon, inure to the benefit
of and be enforceable by the parties and their respective successors and
assigns.
 
  (i) Further Assurances. In the event of any exercise of the Option by
Community, Centerpoint and Community shall execute and deliver all other
documents and instruments and take all other action that may be reasonably

Agreement to be executed as a sealed instrument by their respective officers
thereunto duly authorized, all as of the date first written above.

                              AFFILIATE AGREEMENT
 
                                                                 August  , 1995
 
Community Bankshares, Inc.
43 North Main Street
Post Office Box 739
Concord, New Hampshire 03302-0739
 
Gentlemen:
 
  Pursuant to the terms of the Agreement and Plan of Reorganization dated as
of August 29, 1995 (the "Merger Agreement"), among Community Bankshares, Inc.,
a New Hampshire corporation ("Parent"), a new "interim bank" to be created as
a wholly owned subsidiary of Parent ("Bank Sub"), and Centerpoint Bank, a New
Hampshire trust company ("Centerpoint"). Parent will acquire Centerpoint
through the merger of Bank Sub with Centerpoint (the "Merger"). Subject to the
terms and conditions of the Merger Agreement, at the Effective Time (as
defined in the Merger Agreement), outstanding shares of the common stock, par
value $1.00 per share, of Centerpoint (the "Centerpoint Common Stock") will be
converted into the right to receive shares of common stock, par value $1.00
per share, of Parent (the "Parent Common Stock") on the basis described in the
Merger Agreement.
 
  The undersigned has been advised that as of the date hereof it may be deemed
to be an "affiliate" of Centerpoint, as the term "affiliate" is (i) defined
for purposes of paragraphs (c) and (d) of Rule 145 of the Rules and
Regulations (the "Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") under the Securities Act of 1933, as amended, of
the and/or (ii) used in and for purposes of Accounting Series Releases 130 and
135, as amended, of the Commission, although nothing contained herein shall be
construed as an admission of such fact.
 
  The undersigned understands that the representations, warranties and
covenants set forth herein will be relied upon by Parent, stockholders of
Parent, Centerpoint, other stockholders of Centerpoint and their respective
counsel and accounting firms.
 
  The undersigned represents and warrants to and agrees with Parent that:
 
    1. The undersigned has full power to execute and deliver this Affiliate
  Agreement and to make the representations and warranties herein and to
  perform its obligations hereunder.
 
    2. The undersigned has carefully read this Affiliate Agreement and the
  Merger Agreement and discussed its requirements and other applicable
  limitations upon its ability to sell, transfer or otherwise dispose of
  Parent Common Stock to the extent the undersigned felt necessary, with its
  counsel or counsel for Centerpoint.
 
    3. The undersigned shall not make any sale, transfer, exchange, pledge or
  other disposition of Parent Common Stock in violation of the Act or the
  Rules and Regulations.
 
    4. The undersigned has been advised that the issuance of shares of Parent
  Common Stock to the undersigned in connection with the Merger has been or
  will be registered with the Commission under the Act on a Registration
  Statement on Form S-4. However, the undersigned has also been advised that,
  since, at the time the Merger is to be submitted for a vote of the
  stockholders of Centerpoint the undersigned may be deemed to be an
  affiliate of Centerpoint and the distribution by the undersigned of any
  Parent Common Stock will not have been registered under the Act, the
  undersigned may not sell, transfer or otherwise dispose of Parent Common
  Stock issued to the undersigned in the Merger unless (i) such sale,
  transfer or other disposition has been registered under the Act, (ii) such
  sale, transfer or other disposition is made in conformity with the
  requirements of Rule 145 promulgated by the Commission under the Act, or
  (iii) in the
 
                                      50
<PAGE>
 
  opinion of counsel reasonably acceptable to Parent, such sale, transfer or
  other disposition is otherwise exempt from registration under the Act.
 
    5. Parent is under no obligation to register the sale, transfer or other
  disposition of Parent Common Stock by the undersigned or on its behalf
  under the Act or to take any other action necessary in order to make
  compliance with an exemption from such registration available. Parent
  agrees that it shall make available adequate current public information as
  required by Rule 144(c) promulgated by the Commission under the Act.
 
    6. Stop transfer instructions will be given to Parent's transfer agent
  with respect to the Parent Common Stock and there will be placed on the
  certificates for the Parent Common Stock issued to the undersigned, or any
  substitutions therefor, a legend stating in substance:
 
        "The shares represented by this certificate were issued in a
      transaction to which Rule 145 promulgated under the Securities Act
      of 1933 applies. The shares represented by this certificate may only
      be transferred in accordance with the terms of an Affiliate
      Agreement dated August 29, 1995, between the registered holder
      hereof and Parent, a copy of which agreement is on file at the
      principal offices of Parent."
 
    7. The legend set forth in paragraph 6 above shall be removed by delivery
  of substitute certificates without such legend if the undersigned shall
  have delivered to Parent a copy of a letter from the staff of the
  Commission, or an opinion of counsel in form and substance reasonably
  satisfactory to Parent, to the effect that such legend is not required for
  purposes of the Act.
 
    8. The undersigned will not sell, exchange, transfer, pledge, dispose of
  or grant any option, establish any "short" or put-equivalent position with
  respect to or enter into any similar transaction intended to reduce his
  risk relative to the shares of Parent Common Stock received by the
  undersigned in connection with the Merger, except for de minimis sales with
  the prior written consent of Parent, during the period beginning from the
  date hereof, and ending on the second day after the day Parent publicly
  announces financial results covering at least 30 days of combined
  operations of the Parent and Centerpoint. Parent, at its discretion, may
  cause stop transfer orders consistent with the foregoing to be placed with
  its transfer agent with respect to the certificates for Parent Common
  Stock.
 
    9. (a) The undersigned currently is the beneficial owner of that number
  of shares of Centerpoint Common Stock set forth in Appendix A hereto (the
  "Centerpoint Securities") and, except as otherwise set forth in Appendix A,
  (i) has held Centerpoint Securities at all times since January 1, 1995 and
  (ii) did not acquire any of Centerpoint Securities in contemplation of the
  Merger;
 
    (b) Except as otherwise set forth in Appendix A hereto, the undersigned
  has not engaged in a Sale (as defined below) of any shares of Centerpoint
  Common Stock (including Centerpoint Securities) (i) at any time since
  January 1, 1995 or (ii) in contemplation of the Merger;
 
    (c) The undersigned has no plan or intention (a "Plan") to engage in a
  sale, exchange, transfer, distribution (including a distribution by a
  partnership to its partners or by a corporation to its stockholders),
  redemption or reduction in any way of the undersigned's risk of ownership
  by short sale or otherwise, or other disposition, directly or indirectly
  (such actions being collectively referred to herein as a "Sale") of the
  shares of Parent Common Stock to be received by the undersigned in the
  Merger. For purposes of the preceding sentence, shares of Centerpoint
  Common Stock (or the portion thereof) (i) with respect to which the
  undersigned will receive consideration in the Merger other than Parent
  Common Stock (including, without limitation, cash to be received in lieu of
  fractional shares of Parent Common Stock) and/or (ii) with respect to which
  a Sale (A) occurred after January 1, 1995 or otherwise in contemplation of
  the Merger or (B) will occur prior to the Merger, shall be considered
  shares of Centerpoint Common Stock exchanged for Parent Common Stock in the
  Merger and then disposed of pursuant to a Plan;
 
    (d) The undersigned has no Plan to exercise dissenters' rights in
  connection with the Merger;
 
    (e) The undersigned is not aware of, or participating in, any Plan on the
  part of the stockholders of Centerpoint to engage in a Sale or Sales of the
  Parent Common Stock to be received in the Merger such
 
                                      51
<PAGE>
 
  that the aggregate fair market value, as of the Effective Date of the
  Merger, of the shares subject to such Sales would exceed 50% of the
  aggregate fair market value of all shares of outstanding Centerpoint Common
  Stock immediately prior to the Merger. For purposes of the preceding
  sentence, shares of Centerpoint Common Stock (or the portion thereof) (i)
  with respect to which a Centerpoint stockholder receives consideration in
  the Merger other than Parent Common Stock (including, without limitation,
  cash received pursuant to the exercise of dissenters' rights or in lieu of
  fractional shares of Parent Common Stock) or (ii) with respect to which a
  Sale occurs prior to and in contemplation of the Merger, shall be
  considered shares of outstanding Centerpoint Common Stock exchanged for
  Parent Common Stock in the Merger and then disposed of pursuant to a Plan;
 
    (f) Except to the extent written notification to the contrary is received
  by Centerpoint from the undersigned prior to the Merger, the
  representations contained herein shall be true and correct at all times
  from the date hereof through the date on which the Merger occurs; and
 
    (g) The undersigned has consulted with such legal and financial counsel
  as the undersigned has deemed appropriate in connection with the execution
  of this Agreement.
 
  10. The undersigned understands that Centerpoint, Bank Sub, Parent and their
respective stockholders, as well as legal counsel to Centerpoint and Parent
(in connection with rendering their opinions that the Merger will be a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended) will be relying on (a) the truth and accuracy of the
representations contained herein and (b) the undersigned's performance of the
obligations set forth herein.
 
  11. Except for Centerpoint Securities and options to purchase that number of
shares of Centerpoint Common Stock set forth in Appendix A hereto, the
undersigned does not beneficially own any shares of Centerpoint Common Stock
or any other equity securities of Centerpoint or any options, warrants or
other rights to acquire any equity securities of Centerpoint.
 
  12. For the convenience of the parties hereto, this Affiliate Agreement may
be executed in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same
document.
 
  13. This Affiliate Agreement shall be enforceable by, and shall inure to the
benefit of and be binding upon, the parties hereto and their respective
successors and assigns. As used herein, the term "successors and assigns"
shall mean, where the context so permits, heirs, executors, administrators,
trustees and successor trustees, and personal and other representatives.
 
  14. This Affiliate Agreement shall be governed by and construed, interpreted
and enforced in accordance with the laws of the State of New Hampshire.
 
  15. If a court of competent jurisdiction determines that any provision of
this Affiliate Agreement is not enforceable or enforceable only if limited in
time and/or scope, this Affiliate Agreement shall continue in full force and
effect with such provision stricken or so limited.

                                                                 August  , 1995
 
Community Bankshares, Inc.
43 North Main Street
Post Office Box 739
Concord, New Hampshire 03302-0739
 
Gentlemen:
 
  Each of the undersigned (a "Stockholder") beneficially owns and has sole
voting power with respect to all shares of the common stock, par value $1.00
per share, now owned or hereafter acquired, whether pursuant to the exercise
of stock options or otherwise (the "Shares"), of Centerpoint Bank (the
"Company").
 
  Simultaneously with the execution of this letter agreement, Community
Bankshares, Inc. ("Parent") and the Company are entering into an Agreement and
Plan of Merger (the "Merger Agreement") providing, among other things, for the
merger of a subsidiary of Parent with the Company (the "Merger"). We
understand that Parent has undertaken and will continue to undertake
substantial expenses in connection with the negotiation and execution of the
Merger Agreement and the subsequent actions necessary to consummate the Merger
and the other transactions contemplated by the Merger Agreement.
 
  In consideration of, and as a condition to, Parent's entering into the
Merger Agreement, and in consideration of the expenses incurred and to be
incurred by Parent in connection therewith, each Stockholder and Parent agree
as follows:
 
    1. AGREEMENT TO VOTE IN FAVOR OF MERGER. Each Stockholder specifically
  agrees that: (i) he will use all reasonable efforts to cause a special
  meeting of stockholders of the Company (the "Special Meeting") to be held
  as soon as is practicable to vote to approve the Merger, the Merger
  Agreement and the transactions contemplated thereby, and (ii) at the
  Special Meeting, he will vote all of his Shares in favor of the Merger, the
  Merger Agreement and the transactions contemplated thereby.
 
    2. IRREVOCABLE PROXY. Each Stockholder hereby revokes any proxy
  heretofore granted with respect to any shares of capital stock of the
  Company owned by such Stockholder. Each Stockholder hereby agrees to grant
  to Parent an irrevocable proxy in the form of Exhibit A attached hereto
  upon request of Parent. It is expressly understood and agreed that such
  irrevocable proxy shall be coupled with an interest and that Parent shall
  have no duty, liability and obligation whatsoever to the undersigned
  arising out of the exercise by Parent of such irrevocable proxy unless
  Parent acts in a manner inconsistent with the understandings set forth in
  this Agreement and the Merger Agreement. Without limiting the generality of
  the foregoing, each Stockholder expressly acknowledges and agrees that he
  will not impede the exercise of Parent's rights under the Merger Agreement
  and that Parent shall have the right, pursuant to the irrevocable proxy, to
  vote (i) with respect to all matters relating to the Merger, the Merger
  Agreement or the transactions contemplated thereby, and (ii) with respect
  to any other matter that Parent deems to be inconsistent with the
  consummation of the transactions contemplated by the Merger Agreement.
 
    3. RESTRICTIONS ON SALE OR OTHER DISPOSITION OF SHARES. Each Stockholder
  hereby agrees that from and after the date hereof and until the Effective
  Time of the Merger (as defined in the Merger Agreement), each Stockholder
  will not, directly or indirectly, without the prior written consent of
  Parent, sell, assign, hypothecate, transfer, pledge, give, place in trust
  or dispose of (including, without limitation, by granting of proxies (other
  than proxies not inconsistent with this Agreement, such as proxies relating
  to the routine election of directors), or relinquishment of voting rights,
  with respect to) any of the Shares owned by each Stockholder, except for
  the grant of the irrevocable proxy as provided for herein or any other
  proxies granted to Parent.
 
                                      55

    4. NO SOLICITATION. Neither any Stockholder, nor any of his affiliates,
  employees, representatives or agents or other persons controlled by him
  shall, directly or indirectly, encourage or solicit or hold discussions or
  negotiations with or assist or provide any information to, any person,
  entity or group (other than Parent) concerning any merger, disposition of a
  substantial portion of the Company's assets, acquisition of a substantial
  portion of its capital stock or similar transactions involving the Company
  or any of its subsidiaries or any branch or division of the Company. Each
  Stockholder will immediately communicate to Parent the terms of any
  proposal or offer or any inquiry or request for information which it may
  receive in respect of any such transaction.
 
    5. REPRESENTATIONS AND WARRANTIES. Each Stockholder represents and
  warrants to Parent as follows:
 
      (a) This Agreement has been duly executed and delivered by each
    Stockholder and constitutes his legal and valid obligation enforceable
    against him in accordance with its terms.
 
      (b) He is the record owner of the number of Shares indicated opposite
    such Stockholder's name below; he has plenary voting and dispositive
    power with respect to such Shares; he owns no other shares of capital
    stock of the Company; there are no proxies, voting trusts or other
    agreements or understandings with respect to the voting of any of the
    Shares other than this Agreement; and no Stockholder has entered into
    (and no Stockholder will enter into) any agreement or arrangement in
    any way inconsistent with this Agreement.
 
    6. EQUITABLE REMEDIES. The parties hereto acknowledge that irreparable
  damage would result if this Agreement is not specifically enforced and
  that, therefore, the rights and obligations of the parties under this
  Agreement may be enforced by a decree of specific performance issued by a
  court of competent jurisdiction, and appropriate injunctive relief may be
  applied for and granted in connection therewith. Such remedies shall,
  however, not be exclusive and shall be in addition to any other remedies
  which any party may have under this Agreement or otherwise.
 
    7. NOTICES. All notices or other communications hereunder shall be in
  writing and shall be deemed given if delivered by receipted hand delivery
  or mailed by prepaid registered or certified mail (return receipt
  requested) or by cable, telegram, telex or telecopy addressed as follows:

                  COMMUNITY BANKSHARES, INC., PARENT COMPANY
                 OF CONCORD SAVINGS BANK, AND CENTERPOINT BANK
                         JOINTLY ANNOUNCE MERGER PLANS
 
  Concord, NH--August 30, 1995--Community Bankshares, Inc. (NASDAQ NMS: CBNH)
parent company of Concord Savings Bank, and Centerpoint Bank (NASDAQ: CPOB)
today jointly announced the signing of a definitive merger agreement under
which Centerpoint Bank (Centerpoint) will operate as a separate commercial
bank subsidiary of Community Bankshares, Inc. (Community). Under the
agreement, each share of Centerpoint Bank common stock will be exchanged for
1.073 shares of Community Bankshares, Inc. common stock in what is expected to
constitute a tax free exchange. Based on the last sale of Community common
stock the exchange is worth approximately $17.70 per share exchanged. The
transaction, which will be accounted for as a pooling of interests, is
therefore valued at approximately $10.5 million and is expected to be
accretive to earnings per share of the combined company in the first year. The
proposed transaction is subject to state and federal regulatory approval as
well as approval by shareholders of both companies. As part of the transaction
Centerpoint has issued an option to Community which, under certain conditions,
can be converted into Centerpoint stock equal to 19.9% of the then proforma
common shares outstanding. The merger will approximately double Community's
commercial banking component, and represents for Community its most
significant entry into Hillsborough County, the largest banking market in New
Hampshire.
 
  Centerpoint will retain its local identity and current management, and will
operate as a wholly owned subsidiary of the parent company. It is planned that
Centerpoint will continue its highly successful, personalized business to
business banking approach while gaining increased ability to expand and
develop its product lines, service capability and market outreach in the
southern New Hampshire area.
 
  Centerpoint, a state chartered commercial bank, has $81 million in assets,
is headquartered in Bedford, New Hampshire and operates banking offices in
Manchester and Nashua. Following consummation of this transaction, Community's
two banking subsidiaries would operate a total of 8 banking offices and 4
remote service units in Merrimack and Hillsborough counties. On a consolidated
basis, Community would have total assets of $507 million, total deposits of
$384 million, total loans of $322 million and total stockholders' equity of
$35 million.
 
  In making today's announcement, Douglas Crichfield, president and chief
executive officer of Community stated "We are extremely pleased to have
reached this agreement with Centerpoint Bank. Centerpoint is a profitable,
well run community bank with a proven track record of delivering high quality
commercial banking services to businesses and professionals in Hillsborough
County, the largest market for financial services in New Hampshire. As such,
they bring a great deal of market and product synergy to us, complementing our
dominant position in Merrimack County, home of the State's capital, by
providing a presence in Hillsborough County. Our strong consumer, mortgage and
municipal businesses fit nicely with their commercial banking expertise. We
are eager to join forces with Centerpoint to build upon our individual and
mutual strengths in serving the individuals, businesses and municipalities of
central and southern New Hampshire."

warrant that it has sole record and beneficial ownership of such shares and
that
 
                                       5

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 the FRB or other Governmental
Entity is required in connection with the payment of all or any portion of the
Section 8 Repurchase Consideration or is not then permissible under applicable
law, Centerpoint shall deliver from time to time that portion of the Section 8
Repurchase Consideration that it is not then so prohibited from paying and
shall promptly file the required notice or application for approval and shall
expeditiously process the same (and Community shall cooperate with Centerpoint
in the filing of any such notice or application and the obtaining of any such
approval), and the period of time that otherwise would run pursuant to the
preceding sentence for the payment of the portion of the Section 8 Repurchase
Consideration requiring such notification or approval shall run instead from
the date on which, as the case may be, (i) any required notification period
has expired or been terminated or (ii) such approval has been obtained and, in
either event, any requisite waiting period shall have passed. If the FRB or
any other Governmental Entity disapproves of any part of Centerpoint's
proposed repurchase pursuant to this Section 8, Centerpoint shall promptly
give notice of such fact to Community and redeliver to Community the Option
Shares it has acquired from Community pursuant hereto and is then prohibited
from repurchasing, and Community shall 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 number of shares as to which payment has been made
pursuant to Section 8(b); provided that if the Option shall have expired prior
to the date of such notice or shall be scheduled to expire at any time before
the expiration of a period ending on the thirtieth business day after such
date, Community shall nonetheless have the right so to exercise the Option
until the expiration of such period of 30 business days. Notwithstanding
anything herein to the contrary, Centerpoint shall not be obligated to
repurchase the Option or any shares of Centerpoint Common Stock pursuant to
this Section 8 on more than one occasion.
 
  (d) For purposes of this Agreement, the "Applicable Price" means the highest
                                           ----------------
of (i) the highest price per share at which a tender or exchange offer has
been made for shares of Centerpoint Common Stock after the date hereof and on
or prior to the Request Date, (ii) the price per share to be paid by any third
party for shares of Centerpoint Common Stock or the consideration per share to
be received by holders of Centerpoint Common Stock, in each case pursuant to
an agreement for a merger or other business combination transaction with
Centerpoint entered into on or prior to the Request Date or (iii) the highest
bid price per share as quoted on the principal trading market on which such
shares are traded as reported by a recognized source during the 60 business
days preceding the Request Date. 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 Community and reasonably acceptable to Centerpoint, which
determination shall be conclusive for all purposes of this Agreement.
 
  9. REPURCHASE AT THE OPTION OF CENTERPOINT.
 
  (a) Except to the extent that Community shall have previously exercised its
rights under Section 8, at the request of Centerpoint during the 30-day period
commencing 12 months following the first occurrence of a Repurchase Event,
Centerpoint may repurchase from Community, and Community shall sell to
Centerpoint, all (but not less than all) of the shares of Centerpoint Common
Stock acquired by Community pursuant hereto and with respect to which
Community has beneficial ownership at the time of such repurchase at a price
equal to the greater of (A) 110% of the Current Market Price (as defined
below) or (B) the sum of (1) the Purchase Price in respect of the shares so
acquired plus (2) Community's pre-tax per share carrying cost (as defined
below), multiplied in either case by the number of shares so acquired (the
"Section 9 Repurchase Consideration"); provided that Centerpoint's rights
 ----------------------------------
under this Section 9 shall be suspended (with any such rights being extended
accordingly) during any period when the exercise of such rights would subject
Community to liability pursuant to Section 16(b) of the Exchange Act by reason
of Community's purchase of shares of Centerpoint Common Stock hereunder.
 
  (b) If Centerpoint exercises its rights under this Section 9 and Community
does not sell the shares to a third party pursuant thereto, Centerpoint shall,
within 10 business days after the expiration of the 30-day period referred to
in paragraph (a) above or, if applicable, upon abandonment of the transaction
covered by the Offeror's
 
                                       6
<PAGE>
 
Notice, pay the Section 9 Repurchase Consideration in immediately available
funds, and Community shall surrender to Centerpoint the certificates
evidencing the shares of Centerpoint Common Stock purchased hereunder with
respect to which Community then has beneficial ownership, and Community 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.
 
  (c) As used herein, (i) "Current Market Price" means the average closing
                           --------------------
sales price per share of Centerpoint Common Stock quoted on the principal
trading market on which such shares are traded as reported by a recognized
source for the 10 business days preceding the date of Centerpoint's request
for repurchase pursuant to this Section 9 and (ii) "Community's pre-tax per
                                                    -----------------------
share carrying cost" shall be the amount equal to the interest on the
-------------------
aggregate Purchase Price paid for the shares of Centerpoint Common Stock
purchased from the date of purchase to the date of repurchase at the rate of
interest announced by Bank of Boston as its prime or base lending or reference
rate during such period, less any dividends received on the shares so
purchased, divided by the number of shares so purchased.
 
  10. DIVISION OF OPTION. This Agreement and the Option granted hereby are
exchangeable, without expense, at the option of Community upon partial
exercise of the Option or partial assignment of the Option, in both instances
as provided herein, upon presentation and surrender of this Agreement at the
principal office of Centerpoint, for other Agreements providing for Options of
different denominations entitling the holder thereof to acquire in the
aggregate the same number of shares of Centerpoint Common Stock which may be
acquired hereunder. The terms "Agreement" and "Option" as used herein include
                               ---------       ------

written and oral, between the parties with respect to the subject matter
hereof and (ii) is not intended to confer upon any person other than the
parties hereto any rights or remedies hereunder. If any term, provision,
covenant or restriction of this Agreement is held by a court of competent

remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be

obligations hereunder or under the Option shall be assigned by any of the
parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other party, except that: (i) Community may assign this
Agreement to any subsidiary or affiliate, and (ii) after the occurrence of a
Repurchase Event Community may assign its rights under this Agreement to third

which the Federal Reserve Board approves an application by Community under the
BHC Act to acquire the shares of Centerpoint Common Stock subject to the
Option, Community may not assign its rights under the Option except in a
manner approved by the Federal Reserve Board, and provided, further, that,
notwithstanding any such assignment, Community shall continue to be liable for
