Item 1.  Business
- -----------------

GENERAL

     The Company.   Sandwich Bancorp, Inc. (the "Company"), a Massachusetts
corporation, was organized by The Sandwich Co-operative Bank (the "Bank") to be
a bank holding company.  The Company was organized at the direction of the Bank
in June 1997 to acquire all of the capital stock of the Bank upon the
consummation of the reorganization of the Bank into the holding company form of
ownership (the "Reorganization"), which was completed on September 30, 1997.
The Company's common stock, par value $1.00 per share (the "Common Stock")
became registered under the Securities Exchange Act of 1934 on September 30,
1997.  The Company has no significant assets other than the corporate stock of
the Bank.  For that reason, substantially all of the discussion in this Form 
10-K relates to the operations of the Bank and its subsidiaries.

     The executive offices of the Company are located at 100 Old Kings Highway,
Sandwich, Massachusetts 02563.  The telephone number is (508) 888-0026.

     The Bank.  The Sandwich Co-operative Bank was organized as a Massachusetts
chartered co-operative bank in 1885.  The Bank merged with Wareham Co-operative
Bank in May 1982.  In July 1986, the Bank converted from mutual to stock form
through the sale and issuance of 1,820,833 shares of common stock, par value
$1.00 per share (the "Common Stock").  Since 1986, the Bank's deposits have been
insured by the Federal Deposit Insurance Corporation ("FDIC"), an agency of the
federal government, up to $100,000 per insured depositor, with additional
insurance to the total amount of the deposit provided by the Share Insurance
Fund of The Co-operative Central Bank (the "Central Bank"), a deposit insuring
entity chartered by the Commonwealth of Massachusetts.  The Bank is subject to
regulation by the Massachusetts Commissioner of Banks ("Commissioner") and the
FDIC.

     The business of the Bank consists primarily of attracting deposits from the
general public and originating both construction and permanent loans on one-to-
four family homes.  The Bank also makes consumer loans, home equity loans and
commercial loans and mortgages.  The Bank invests a portion of its funds in
money market instruments, federal government and agency obligations, and various
types of corporate securities and other authorized investments.

     The principal sources of funds for the Bank's lending and investment
activities are deposits, loan payments and payoffs, investment income and
maturities, and principal payments on investments, mortgage-backed securities
and collateralized mortgage obligations.  As additional sources of funds, the
Bank has access to advances from the Federal Home Loan Bank of Boston and other
borrowings.  The Bank's principal sources of income are interest on loans and
loan origination fees, interest and dividends on investment securities,
mortgage-backed securities and collateralized mortgage obligations and short-
term investments, customer service charges and gains on the sale of loans in the
secondary market, as well as income from servicing loans sold.  Its principal
expenses are interest paid on deposits and general and administrative expenses.

     The Bank's deposit and lending operations are conducted through eleven full
service office facilities located in Sandwich, South Sandwich, Buzzards Bay,
Pocasset, Wareham, Cedarville, Falmouth, Hyannis, Chatham, Orleans and South
Yarmouth, Massachusetts.  In addition, the Bank maintains a loan production
office in Plymouth, Massachusetts.  Significant events contributing to the
structure of the current branch network are described below.

     In February 1996 and May 1996 the Bank opened free standing ATMs in
Cedarville and South Sandwich, Massachusetts, respectively, in order to provide
greater convenience and access to accounts for its customers.  In addition to
its existing ATM network offerings of X-Press 24, NYCE, CIRRUS/MasterCard, the
Bank recently added the Plus/VISA networks for users of Bank ATMs.

                                       2
<PAGE>
 
     In June 1996, the Bank entered into an agreement with FISCO, a national
financial services group that provides a variety of investment services through
community banks to offer expanded retirement investments and financial planning.
FISCO will provide Bank customers with access to alternative investments,
including mutual funds and annuities from a number of highly rated companies.

     The Bank also established a referral arrangement with State Street Global
Advisors which enables customers to avail themselves of the estate planning and
trust services of a nationally respected trust institution.

     The Bank's main office is located at 100 Old Kings Highway, Sandwich,
Massachusetts 02563 and its telephone number is (508) 888-0026.

RECENT EVENTS

     On February 2, 1998, the Company and the Bank entered into a definitive 
agreement under which Compass Bank of New Bedford, Massachusetts will acquire 
Sandwich Bancorp, Inc. Prior to the Company's consideration and approval of its 
definitive agreement with Compass Bank, the Company had contacted and received 
expressions of interest from three other parties who had expressed an interest 
in an acquisition of the Company.

     On February 24, 1998, the Company announced that its Board of Directors, 
consistent with the exercise of its fiduciary duties, determined that it was 
appropriate to request additional information and clarification of the renewed 
expressions of interest that it had received from three other parties subsequent
to February 2.

     Following a comprehensive review of the other expressions of interests for 
the Company, the Company and Compass Bank jointly announced on March 23, 1998, 
that they have signed an amendment to their previously announced agreement of 
February 2, 1998 (the "Amended Agreement") by which Compass Bank would acquire 
Sandwich Bancorp, Inc. Under the terms of the Amended Agreement, Compass Bank's 
parent company, The 1855 Bancorp will convert to a 100% publicly owned stock 
holding company and thereafter issue stock having a value of $64.00 per share to
Sandwich Bancorp shareholders in a tax-free exchange of common stock. The value 
to be received by Sandwich Bancorp shareholders is subject to adjustment 
pursuant to a formula based on the value of the stock of The 1855 Bancorp near 
the transaction date. Based on 1855 Bancorp's assumed initial public offering 
price of $10.00 per share, each Sandwich Bancorp share will be exchanged for 
1855 Bancorp stock having a value of $64.00 per share so long as 1855 Bancorp 
stock trades at an average price of between $10.00 and $13.50 per share during a
designated trading period following the initial public offering date. If this 
average price exceeds $13.50 per share, the value to be received by Sandwich 
Bancorp shareholders will increase proportionately up to a maximum value of
$71.11 until 1855 Bancorp's average price reaches or exceeds $15.00 per share.
If this average price is equal to or less than $10.00 per share, Sandwich
Bancorp shares will be exchanged for 6.4 shares of 1855 Bancorp stock.

     Sandwich Bancorp and The 1855 Bancorp also entered into a Stock Option 
Agreement, granting to The 1855 Bancorp an option to acquire up to 19.9% of 
Sandwich common stock under certain circumstances. The transaction, which is 
subject to all necessary regulatory and shareholder approvals, is expected to 
close in the fourth quarter of 1998.

     For additional information, reference is made to the Amended and Restated 
Affiliation and Merger Agreement, dated as of March 23, 1998, attached hereto as
Exhibit 2.1, and the Stock Option Agreement dated as of March 23, 1998, attached
hereto as Exhibit 2.2.


                                       3

     The expression of interest from CCB&T, which the Company disclosed on
February 17, 1998, as well as those from FirstFed America and Independent, were
all received subsequent to the execution and announcement on February 2, 1998 of
the Company's Merger Agreement with Compass Bank.  The Merger Agreement with
Compass Bank, which remains in effect and to which the Company is bound,
provides for a cash purchase price of $53 per share.

     The Company cautioned there can be no assurance that any of these
expressions of interest will result in a transaction, or a transaction which is
different from the Company's previously announced Merger Agreement with Compass
Bank, or that the value to be obtained will be equal to the nominal value
proposed by each of these parties.  Upon receipt of the new information
requested from each of these parties, the Company's Board of Directors will make
a determination as to how it will proceed.

LENDING ACTIVITIES

     GENERAL.  The Bank's net loan portfolio totaled $366.6 million as of
December 31, 1997, which represented 70.7% of total assets.  The Bank offers
residential and home equity mortgage loans, commercial real estate loans,
commercial business loans, construction loans, and personal, automobile, boat,
education and other types of consumer loans.  During the year ended December 31,
1997, the Bank originated mortgage loans totaling $123.2 million and purchased
loans totaling $18.3 million for total mortgage loan originations and purchases
of $141.5 million, compared to $117.4 million in mortgage loans originated, and
$23.7 million in mortgage loans purchased for total mortgage loan originations
and purchases of $141.1 million during the year ended December 31, 1996.
Included in the Bank's mortgage loan originations for the year ended December
31, 1997 were $20.8 million of fixed rate residential loans of which $17.4
million were sold in the secondary mortgage market and the difference of $3.4
million was placed into the loan portfolio under the direction of senior
management, as "fixed construction" and "fixed upon completion" mortgage loans.
The increase in mortgage loan originations during fiscal 1997 as compared to
fiscal 1996 was a direct result of a strong residential real estate market.
Residential construction mortgages decreased from 175 loans totaling $27.9
million in 1996 to 156 loans totaling $19.8 million in 1997.  In addition, the
purchase of new homes and re-sales of existing homes increased over 1997.  In
early 1996, the Bank began a correspondent relationship with Anchor Mortgage
Co., Conway Financial Services and National City Mortgage (formerly known as
Commonwealth United Mortgage), which generated an additional $25.2 million (164
loans) in loan volume during 1997.

     RESIDENTIAL LENDING.  The Bank's residential mortgage loan program
currently includes the origination of a variety of adjustable rate loans which
are retained in the Bank's loan portfolio.  At December 31, 1997, the Bank's
adjustable rate residential mortgages totaled $232.9 million, or 63.5%, of the
residential mortgage loan portfolio.  Fixed-rate loans accounted for $15.0
million, or 4.1%, of the residential mortgage loan portfolio at that date.  The
Bank stresses the origination of adjustable rate mortgages for retention in its
portfolio. The Bank continued to actively originate fixed rate loans for sale in
the secondary mortgage market. By retaining the servicing on loans sold, the
Bank generates loan servicing fee income.

     The Bank's adjustable rate residential mortgage loans have a maximum term
of 35 years, and allow for periodic interest rate adjustments.  The initial
offering rates on these loans may be discounted to remain competitive prior to
their first interest rate adjustment.  The payment amount and the interest rate
on the one year adjustable rate loan adjusts annually to 2.75% above the weekly
average yield of the one year U.S. Treasury Securities (at time of adjustment)
with a maximum interest rate adjustment of 2% per year and 6% over the term of
the loan.  Interest rates on the three year adjustable rate loans are fixed for
the first three years by reference to various market indices and competitive
rates, and rates are adjusted every three years thereafter to 2.875% above the
weekly average yield of three year U.S. Treasury Securities (at time of
adjustment) with a maximum interest rate adjustment of 2% every three years, and
6% over the term of the loan.  In 1997, the Bank began offering a 4/3 adjustable
rate mortgage loan.  The interest rate is fixed for the first four years and
then becomes a three year adjustable rate mortgage which adjusts every three
years at 2.875% above the weekly average yield of the three year U.S. Treasury
Securities, with a maximum interest rate adjustment of 2% per year and 3% over
the remaining term of the loan.  The Bank also offers a 5/1 year adjustable rate
mortgage.  The interest rate is fixed for the first five years and then becomes
a one year adjustable rate mortgage which adjusts annually at 2.75% above the
weekly average yield of the one year U.S. Treasury Securities, with a maximum
interest rate adjustment of 2% per year and 5% over the remaining term of the
loan.

     Residential loans may be made as construction loans or as permanent loans
on one-to-four family residential properties and are typically written in
amounts up to 95% of appraised value.  The Bank makes fixed and adjustable rate
mortgage loans of up to 95% of appraised value, if the property is owner
occupied.  All loans in excess of 80% of appraised value require private
mortgage insurance, with the exception of the Bank's adjustable rate First-Time
Home Buyer products, which does not require private mortgage insurance.

     As noted above, adjustable rate residential mortgage loans originated for
retention in the Bank's loan portfolio provide for periodic interest rate
adjustments.  Despite the benefits of adjustable rate mortgages to the Bank's
asset and liability management program, such mortgages pose risks, because as
interest rates rise, the underlying payments by the borrowers rise, increasing
the potential for default.  At the same time, the marketability of the
underlying property may be adversely affected by higher interest rates.  One of
the ways the Bank seeks to protect itself on these loans is by generally
requiring private mortgage insurance as stated above.

     CONSTRUCTION LENDING.  The Bank's construction loans totaled $32.5 million,
or 8.9%, of the Bank's total loan portfolio at December 31, 1997.  Construction
loans originated during the years ended December 31, 1997 and 1996 totaled $34.4
million and $36.0 million, respectively.

     The Bank lends to individuals for the construction of residential
properties which they intend to occupy as a primary or secondary residence.
Borrowers are required to have a firm contract with a qualified builder.  Such a
construction loan is generally made with the first twelve months designated as
the construction period (six months for fixed construction) after which time the
loan converts to a 30-35 year permanent residential real estate loan.  A maximum
loan to value ratio of 95% of the value of the completed property, or 95% of the
total cost to construct, whichever is less, is permitted as determined by
appraisers.  The majority of the Bank's construction loans are made for the
construction of pre-sold, pre-approved residential homes.  Inspections of the
construction sites are primarily performed by independent inspectors.

                                       7
<PAGE>
 
     Due to the active real estate market in 1997, the Bank provided financing
to established, credit worthy builders for the purpose of funding construction
of residential homes which had either been pre-sold or constructed on
speculation.  Sound underwriting standards were adhered to, minimizing the
inherent risks associated with construction lending.  The total loan exposure to
any one builder was well within the prudent levels established by management.
All builder construction loans are performing as anticipated.

     COMMERCIAL REAL ESTATE LENDING.  The Bank also originates loans secured by
real estate other than one-to-four family residential properties.  These
commercial real estate loans generally bear interest at variable rates based
upon a margin of one to two percent above the prime interest rate as quoted in
The Wall Street Journal, and such rates adjust when The Wall Street Journal
prime rate changes.  In June 1996, the Bank started offering three year
adjustable rate commercial real estate loans where the interest rate is fixed
for the first three years, generally at 9 1/4%.  After the initial three year
period, the interest rate adjusts every three years thereafter to a margin of
one and one half percent above the prime interest rate as quoted in The Wall
Street Journal. This product has enabled the Bank to be more competitive with
its product offerings. There were $62.6 million in commercial real estate loans
outstanding, which comprised 17.1% of the Bank's total loan portfolio at
December 31, 1997. In some cases, commercial real estate loans are made through
participations with other banks. Commercial real estate loans are generally
written in amounts of up to 75% of the appraised value of the property and all
commercial real estate loans over $100,000 are appraised by independent
appraisers. In addition, the Bank's underwriting procedures require verification
of the borrower's credit history and income, banking relationships, references
and income projections for the property. In certain cases, borrowers may be
required to provide additional collateral for loans made. All property securing
commercial loans is revalued or inspected periodically as required under
Massachusetts law. It is the Bank's policy to use the same underwriting
procedures for loan participations as for loans originated by the Bank. The Bank
grants loans guaranteed by the Small Business Administration as well as by the
Massachusetts Business Development Corporation's Capital Access Program.
Although the Bank is permitted to grant commercial real estate loans in
substantially greater amounts, the Bank's current policy generally limits new
commercial real estate loan originations to $2,000,000 to any individual or
entity.

     CONSUMER AND OTHER LOANS.  The Bank's consumer and other loans totaled
$27.4 million on December 31, 1997, representing 7.5% of the total loan
portfolio on that date.  In addition to consumer loans, including personal and
automobile loans, the Bank makes education loans under the  American Student
Assistance Corporation ("A.S.A.") program, which are serviced by Sallie Mae,
Inc.  The interest on education loans is partially subsidized by the Federal
Government and the principal is fully guaranteed by A.S.A.  The Bank sells its
student loans to Sallie Mae once the loan has begun repayment.

     The Bank offers a home equity line of credit whereby the Bank makes monthly
adjustable rate loans, secured by the borrower's equity in their residence,
whether or not the loans are to be used for home improvements.  As of December
31, 1997, the Bank had $12.4 million in home equity loans outstanding or 3.4% of
the Bank's total loan portfolio, as compared with $12.3 million in such loans
outstanding at December 31, 1996 or 3.9% of the Bank's total loan portfolio at
that date.  Home equity loans are currently written in amounts up to 80% of the
appraised value of the property less the outstanding balance of the existing
first mortgage.

     The Bank offers a three year adjustable home equity loan.  The interest
rate for each three year period is based upon a margin of 3.0% above the prime
interest rate as quoted in The Wall Street Journal.  The home equity loan has a
maximum interest rate adjustment of 3.0% per adjustment, and a ceiling interest
rate of 18.0%.  The home equity loan amount is fully drawn down at closing.

     The Bank offers a commercial line of credit program for its established
business customers with seasonal cash flow needs.  The Bank's home equity line
of credit loans and commercial lines of credit accounts generally bear interest
at variable rates based upon a margin 1 - 3% above the prime interest rate as
quoted in The Wall Street Journal, while other loans are generally priced based
on market conditions.

     The Bank believes its consumer lending programs create diversity and
interest rate sensitivity within its asset mix and offer attractive yields.  The
Bank is currently promoting its construction, consumer and home equity lending
programs through the activities of its loan officers, branch managers and
customer service personnel, and is utilizing careful underwriting and monitoring
procedures in these programs.

     RISKS OF COMMERCIAL, CONSTRUCTION AND CONSUMER LENDING.  Commercial real
estate, construction and consumer lending may entail additional risks compared
to residential mortgage lending.  Commercial real estate and construction loans
may involve large loan balances to single borrowers or groups of related
borrowers.  In addition, the payment experience on loans secured by income
producing properties is typically dependent on the successful operation of the
properties and thus may be subject to a greater extent to adverse conditions in
the local real estate market or in the economy generally.  Construction loans
may involve additional risks, because the uncertainties inherent in estimating
construction costs, delays arising from labor problems, material shortages, and
other unpredictable contingencies, which make it relatively difficult to
evaluate accurately the total loan funds required to complete a project, and
related loan-to-value ratios.  Because of these factors, the analysis of
prospective construction loan projects requires an expertise that is different
in significant respects from the expertise required for residential mortgage
lending.  Consumer loans and particularly unsecured personal loans may involve
additional risks, and it may be expensive and time consuming to recover the
money lent in the event of a default.  While the Bank has attempted to limit the
risk of loss on its commercial real estate, construction and consumer loans, and
has established provisions for loan losses, a reversal in the current positive
trend in the New England real estate market could negatively affect the Bank's
commercial real estate, construction and consumer loan portfolios, which would
further negatively affect the Bank's results of operations. In addition, the
status of the Bank's problem assets could be impacted by a reversal in the
continuing improvement in the New England real estate market and the Bank's
market area.

     The following table indicates the amounts of construction and commercial
loans which are due after one year from December 31, 1997 that earn interest at
fixed rates and adjustable rates.

     ORIGINATION FEES AND OTHER FEES.  The Bank offers real estate loans with
and without origination fees.  During 1997, customer preference tended towards
the "no point," higher rate loans, both adjustable and fixed.  The Bank does
charge the customer for expenses incurred during the loan application process to
cover such items as real estate appraisal, credit report, etc.  The Bank retains
late charges on all real estate loans that are more than fifteen days late.  For
information regarding the manner in which fees are taken into income, see Note 1
of Notes to Consolidated Financial Statements contained in the Company's 1997
Annual Report to Stockholders (the "Annual Report"), which is Exhibit 13 to this
report.

     LOAN SOLICITATION AND APPROVAL PROCEDURES.  Loan originations are developed
by the Bank's officers, managers, assistant branch managers, customer service
representatives, and loan originators from a number of sources, including
referrals from realtors, builders, attorneys and customers.  Consumer loans are
solicited from existing depositors and loan customers.  Various advertising
forums are also used to promote the Bank's lending programs.

     Applications for all types of loans are taken at all of the Bank's offices
and mortgage loan applications are forwarded to the Bank's loan department for
processing.  The Bank's loan underwriting procedures include the use of detailed
credit applications, property appraisals and verifications of an applicant's
credit history, employment situations and banking relationships.  Loans up to
and including $500,000 may be approved by the Bank's senior loan officer, while
those over $500,000 must be approved by the Bank's Security Committee before
they close.  All mortgage loans are approved or ratified by the Security
Committee and/or the full Board of Directors.  All residential loans and
commercial mortgages over $100,000 are appraised by independent state certified
appraisers selected by the Bank.  Title insurance and fire and casualty
insurance are required on all security properties.

     Mortgage applicants are promptly notified of the decision concerning their
application by a commitment letter setting forth the terms and conditions of the
decision.  If approved, these commitments include the amount of the loan,
interest rate, amortization term, brief description of the real estate mortgaged
to the Bank, the required amount of fire and casualty insurance to be maintained
to protect the Bank's interest and other special conditions as warranted.

     LOAN ORIGINATIONS, PURCHASES AND SALES.  The Bank uses the underwriting
standards and standard documents of the Federal Home Loan Mortgage Corporation

     NON-PERFORMING ASSETS AND ASSET CLASSIFICATION.  Once a loan payment is 15
days past due, the Bank notifies the borrower of the delinquency.  Repeated
contacts are made if the loan remains in a delinquent status for 30 days or
more.  While generally the Bank is able to work out satisfactory repayment with
a delinquent borrower, the Bank will undertake foreclosure proceedings if the
delinquency is not otherwise resolved when payments are 90 days past due.
Property acquired by the Bank as a result of foreclosure or by deed in lieu of
foreclosure is classified as "other real estate owned" until such time as it is
sold or otherwise disposed.  When such property is acquired it is recorded at
the lower of unpaid principal balance of the related loan or its fair value,
less costs to dispose.  Beginning for the year ended December 31, 1993, the Bank
has classified its non-performing assets in accordance with FDIC classification
regulations, so that all loans secured by residential real estate are considered
residential loans, regardless of whether they are owner-occupied or are
investment properties.  During the year ended December 31, 1997, the Bank
foreclosed on

                                       12

eleven loans totaling $1,245,000 of which nine were residential mortgage loans
totaling $728,000 and two were commercial real estate loans totaling $517,000.
The Bank charged off $397,000 on various other loans during fiscal 1997.

     The following table sets forth information with respect to the Bank's non-
performing assets at the dates indicated. At December 31, 1997, the Bank had one
restructured loan within the meaning of the Financial Accounting Standards Board
("FASB") Statement of Financial Accounting Standards ("SFAS") No. 15 which are
described below.

     At December 31, 1997, the Bank had 46 loans, totaling $3.6 million which
were non-accruing.  Non-accruing loans at December 31, 1997 included in the
above total were: (i) 27 loans on residential properties, including two land
loans, totaling $2.8 million with balances outstanding ranging from $2,000 to
$712,000; (ii) eight loans on commercial real estate properties, totaling
$600,000, with balances outstanding ranging from $30,000 to $111,000; (iii)
three home equity loans with combined balances outstanding of $82,000 and (iv)
$121,000 in various other loans.  Reserves of $4.1 million have been established
by the Bank at December 31, 1997 to cover any losses that may be incurred on
loans.

     Restructured loans at December 31, 1997 amounted to $105,000.  Additional
interest income of approximately $2,000 would have been recorded on these
restructured loans during the year ended December 31, 1997 if they had been
performing in accordance with their original terms.  Interest income actually
recorded on these loans for the year amounted to approximately $9,000.
Typically, restructured loans are restructured to provide either a reduction of
the interest on the loan principal or an extension of the loan maturity.

     Real estate acquired by foreclosure at December 31, 1997 totaled $596,000,
representing the lower of the carrying value of the loan or the fair value less
costs to dispose of properties.  These properties had secured six loans which
were foreclosed upon by the Bank.  The largest of these foreclosed properties,
carried at $167,000 at December 31, 1997, is comprised of one residential loan.
For further information regarding the Bank's non-performing assets, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and Note 4 of Notes to Consolidated Financial Statements contained
in the Annual Report.

ALLOWANCE FOR LOAN LOSSES

     The Bank maintains an allowance for losses on loans.  The annual provision
for loan losses is determined by management on the basis of many factors
including the risk characteristics of the portfolio, current economic conditions
and trends in loan delinquencies and charge-offs.  The provision for loan losses
charged to earnings totaled $750,000 and $265,000 for the years ended December
31, 1997 and 1996, respectively.  The Bank increased its provision for loan
losses for the year ended December 31, 1997, as compared to the year ended
December 31, 1996 as a result of the overall increase in the loan portfolio and
an increase in specific loan charge-offs.  The allowance for loan losses was
$4.1 million at December 31, 1997.  The allowance for loan losses is reviewed by
management on a continual basis and although management currently believes this
allowance to be adequate, there can be no assurance that this allowance will be
sufficient to cover future losses.

INVESTMENT ACTIVITIES

     The Bank's management believes it prudent to maintain an investment
portfolio that provides not only a source of income but also a source of
liquidity to meet lending demands and fluctuations in deposit flows. The
relative mix of investment securities and loans in the Bank's portfolio is
dependent upon the comparative attractiveness of yields available to the Bank on
adjustable rate loans that it makes as compared to yields on short-term
investment securities. At December 31, 1997, the Bank's portfolio of short-term
investments, equity securities, mortgage-backed securities and collateralized
mortgage obligations totaled $110.7 million, which represented 21.3% of total
assets. Sales of equity securities during the year ended December 31, 1997
resulted in a net gain of $55,000. There were no sales of equity securities for
the year ended December 31, 1996. The fair value of the Bank's equity securities
portfolio as of December 31, 1997 totaled $6,000. For more information, see Note
3 of Notes to Consolidated Financial Statements in the Annual Report.

     The Bank's portfolio of investment securities consists of securities
offering reasonably short maturities or adjustable interest rates, primarily
United States Treasury notes and Government agency obligations, mortgage-backed
securities, collateralized mortgage obligations, investment grade corporate
bonds, money market instruments and municipal tax anticipation notes. The
average life of the Bank's fixed-income investment portfolio was less than three
years at December 31, 1997, with final maturities greater than ten years. The
Bank's investment portfolio is presently managed by the Bank's Chief Financial
Officer.

DEPOSIT ACTIVITIES AND OTHER SOURCES OF FUNDS

     GENERAL.  Checking, savings and investment deposits have traditionally been
an important source of the Bank's funds for use in lending and for other general
business purposes.  In addition to deposits, the Bank derives funds from loan
repayments, selling loans, and from other operations.  The availability of funds
is influenced by general interest rates and other market conditions.  Scheduled
loan repayments are a relatively stable source of funds while deposit inflows
and outflows vary widely and are influenced by prevailing interest rates and
money market conditions.  Borrowings may be used on a short-term basis to
compensate for reductions in deposits or deposit inflows at less than projected
levels and may be used on a longer term basis to support expanded lending
activities, or to take advantage of favorable investment opportunities.

     DEPOSITS.  Consumer deposits are attracted principally from within the
Bank's market area through the offering of a broad selection of deposit
instruments including demand deposit accounts, NOW accounts, money market
deposit accounts, regular savings accounts, term deposit accounts and retirement
savings plans.  The Bank does not actively solicit or advertise for deposits
outside of its market area.  The Bank accepts deposits primarily through its
branch office network and through the "X-Press 24" automated teller machine
network, of which it is a member.  The Bank also actively solicits deposits from
area businesses as part of its Business Services offerings and seeks to attract
deposits from local municipalities.

     The Bank has adopted a policy of controlled deposit growth, by pricing its
savings products based on the Bank's need for additional funds and rates being
paid by other area financial institutions.

     The Bank offers its customers a variety of pricing options which enable
them to select the combination of banking services which best meets their needs,
in the most cost effective manner.

     In August 1994, the Bank introduced a new relationship banking product
called "Advantage CD."  With this deposit offering, customers have the
opportunity to earn bonus interest each month, based upon their total deposit
and loan account balances with the Bank.  As of December 31, 1997, over $78.1
million had been deposited into the 18 and 30 month Advantage CD's.  In January
1996, the Bank reintroduced its club program, as the Presidents Club, producing
a package of benefits for customers with combined balances of $10,000 or more.
During 1997, Presidents Club household deposits with the Bank grew by $31.3
million to $179.3 million at December 31, 1997.  In August 1997, a high rate,
high minimum balance money market account was introduced, resulting in deposits
of $19.8 million by year end 1997.

     For further information regarding the Bank's deposits see Note 8 of Notes
to Consolidated Financial Statements in the Annual Report.

     BORROWINGS.  Savings deposits and loan repayments, as well as principal
payments and maturing investments, are the primary source of funds of the Bank's
lending and investment activities and for its general business purposes.
Advances from the Federal Home Loan Bank ("FHLB") of Boston and other borrowings
in the form of securities sold under agreements to repurchase, are alternative
sources of funds.  The Bank increased its advances from the FHLB of Boston to
finance loan originations, loan purchases and purchases of investment 
securities.  Advances from the FHLB of Boston were $45.6 million at December 
31, 1997 compared to $32.1 million at December 31, 1996.  Additional sources 
of available funds include the Co-operative Central Bank Reserve Fund and the 
Federal Reserve System.

SUBSIDIARY ACTIVITIES

     The Sextant Corporation (the "Corporation") is a wholly-owned subsidiary of
the Bank, originally formed to purchase equipment and lease the equipment to the
Bank to take advantage of favorable tax treatment previously but no longer
allowed to such transactions.  In fiscal 1989, the Corporation constructed four
office condominium buildings which contain a total of sixteen thousand square
feet of office space (16 units).  At December 31, 1997, eight units had been
sold, and two units have been leased.  The Bank occupies the remaining units.
The Corporation also owns seven condominium units in Cedarville, Massachusetts.
These units have been written down to their appraised value and are actively
being marketed.  The sales price for the units has been reduced as of March 1,
1997 to help facilitate a sale.  No further losses are anticipated; the current
book value as of December 31, 1997 is $233,000.

     The Company in its application to the Federal Reserve Bank of Boston
("FRB") to become a bank holding company committed to divest or convert to bank
premises the properties that are currently held by the Sextant Corporation
including the properties discussed above, pursuant to (S)225.22(f) of Regulation
Y.  Section 225.22(f) of Regulation Y, which stipulates that a company that
becomes a bank holding company may, for a period of two years, engage in
nonbanking activities and control voting securities or assets of a nonbank
subsidiary, if the bank holding company engaged in such activities or controlled
such voting securities or assets on the date it became a bank holding company.
The FRB may grant requests for up to three one-year extensions of the two-year
period.

     The Corporation is also a 49% partner in the Glasstown Group Partnership.
In July 1996, the Partnership sold approximately 12 acres of land on Old Kings
Highway adjacent to a major retail complex in Sandwich, Massachusetts.  The
Corporation received $113,000 in cash and a note receivable for $174,000.
Principal and interest is payable in quarterly payments over a five year period.
The Corporation sustained no loss as a result of the transaction.  At December
31, 1997, the Corporation's portion of the note receivable was $135,000.

                                       19
<PAGE>
 
     In March 1992, the Bank established Redeil Corporation ("Redeil"), a
Massachusetts Corporation which was established in order to allow the Bank to
transfer certain real estate owned by foreclosure to Redeil.  The Bank
transferred $903,000 in real estate owned by foreclosure to Redeil in March
1992, and made an additional investment in Redeil of $20,000 in June 1992.  At
July 31, 1995, the Bank dissolved Redeil and transferred its investment of
$791,000, including a real estate owned by foreclosure balance of $135,000, back
to the Bank.

     In February 1993, the Bank established Sandwich Securities Corporation
("SSC"), a Massachusetts corporation for the purpose of engaging exclusively in
buying, selling and holding, on its own behalf, securities that may be held
directly by the Bank.  SSC qualifies under Massachusetts General Laws, Chapter
63 Section 38B, as a Massachusetts security corporation.  At December 31, 1997,
SSC held $39.6 million in U.S. Treasury notes and Government agency obligations
and mortgage-backed securities.  In March 1995, the Bank established Sextant
Securities Corporation ("SEXT"), a second Massachusetts security corporation,
for the purpose of engaging exclusively in buying, selling and holding, on its
own behalf, securities that may be held directly by the Bank.  At December 31,
1997, SEXT held $30.3 million in securities.

     In February 1997, the Bank filed for and received permission from the
Massachusetts Commissioner of Banks to increase the amount of securities to be
held by SSC from the original amount of $15 million to an amount not to exceed
$45 million.

YIELDS EARNED AND RATES PAID

     The Bank's pre-tax earnings depend primarily on its net interest income,
the difference between the income it receives on its loan portfolio and other
investments and its cost of money, consisting primarily of interest paid on
savings deposits, FHLB advances and other borrowings.  Net interest income is
affected by (i) the difference ("interest rate spread") between rates of
interest earned on its interest-earning assets and rates paid on its interest-
bearing liabilities and (ii) the relative amounts of its interest-earning assets
and interest-bearing liabilities.  When interest-earning assets approximate or
exceed interest-bearing liabilities, any positive interest rate spread will
generate net interest income.  Thrift institutions have traditionally used
interest rate spreads as a measure of net interest income.  Another indicator of
an institution's net interest income is its "net yield on interest earning
assets" which is net interest income divided by average interest earning assets.

     At December 31, 1997, approximately 6.4% of the Bank's total loans
outstanding consisted of fixed-rate loans with maturities of up to 30 years.
Although actions taken by management have largely reduced the Bank's reliance 
on long-term fixed-rate assets in favor of short-term repricable assets, when 
interest rates rise, the Bank's yield on its loan portfolio still increases at
a slower pace as the Bank's deposit base has a shorter term than its loan 
portfolio and is more sensitive to rapidly increasing or decreasing rates.

REGULATION AND SUPERVISION OF THE BANK

     GENERAL.  The Bank is subject to extensive regulation by the Massachusetts
Commissioner of Banks and the FDIC.  The lending activities and other
investments of the Bank must comply with various federal regulatory
requirements.  The Massachusetts Commissioner of Banks and FDIC periodically
examine the Bank for compliance with various regulatory requirements.  The Bank
must file reports with the Commissioner and the FDIC describing its activities
and financial condition.  The Bank is also subject to certain reserve
requirements promulgated by the Board of Governors of the Federal Reserve System
(the "Federal Reserve Board").  This supervision and regulation is intended
primarily for the protection of depositors.  Certain of these regulatory
requirements are referred to below or appear elsewhere herein.

     CAPITAL REQUIREMENTS.  Under FDIC regulations, state-chartered banks that
are not members of the Federal Reserve System ("state nonmember banks") are
required to maintain a minimum leverage capital requirement consisting of a
ratio of Tier 1 capital to total assets of 3% if the FDIC determines that the
institution is not anticipating or 

                                       20
<PAGE>
 
experiencing significant growth and has well-diversified risk, including no
undue interest rate risk exposure, excellent asset quality, high liquidity, good
earnings and in general a strong banking organization, rated composite 1 under
the CAMEL rating system. For all but the most highly rated institutions meeting
the conditions set forth above, the minimum leverage capital ratio is 3% plus an
additional "cushion" amount of at least 100 to 200 basis points so that the
ratio of Tier 1 capital to total assets is not less than 4%. Tier 1 capital is
the sum of common stockholders' equity, noncumulative perpetual preferred stock
(including any related surplus) and minority interests in consolidated
subsidiaries, minus all intangible assets (other than certain purchased mortgage
servicing rights and purchased credit card relationships), minus identified
losses and minus investments in securities subsidiaries.

     In addition to the leverage ratio, state nonmember banks must maintain a
minimum ratio of qualifying total capital to risk-weighted assets of at least
8.0% of which at least four percentage points must be Tier 1 capital.
Qualifying total capital consists of Tier 1 capital plus Tier 2 (supplementary)
capital items, which include allowances for loan losses in an amount of up to
1.25% of risk-weighted assets, perpetual preferred stock that does not qualify
as Tier 1 capital and long-term preferred stock with an original maturity of at
least 20 years and certain other capital instruments.  The includable amount of
Tier 2 capital cannot exceed the institution's Tier 1 capital.  Qualifying total
capital is further reduced by the amount of the bank's investments in banking
and finance subsidiaries that are not consolidated for regulatory capital
purposes, reciprocal cross-holdings of capital securities issued by other banks
and certain other deductions.  Under the FDIC risk-weighting system, all of a
bank's balance sheet assets and the credit equivalent amounts of certain off-
balance sheet items are assigned to one of four broad risk weight categories.
The aggregate dollar amount of each category is multiplied by the risk weight
assigned to that category.  The sum of these weighted values equals the bank's
risk-weighted assets.

     At December 31, 1997, the Bank's ratio of Tier 1 capital to total assets
was 7.80%, its ratio of Tier 1 capital to risk-weighted assets was 13.52% and
its ratio of total capital to risk-weighted assets was 14.77%.

     All Massachusetts chartered co-operative banks are required to be members
of the Share Insurance Fund.  The Share Insurance Fund maintains a deposit
insurance fund which insures all deposits in member banks which are not covered
by federal insurance, which in the case of the Bank are its deposits in excess
of $100,000 per insured account.  In past years, a premium of 1/24 of 1% of
insured deposits has been assessed annually on member banks such as the Bank for
this deposit insurance.   However, no premium has been assessed in recent years.

     DIVIDEND LIMITATIONS.  The Bank may not pay dividends on its capital stock
if its regulatory capital would thereby be reduced below the amount then
required for the liquidation account established for the benefit of certain
depositors of the Bank at the time of its conversion to stock form.

     Earnings of the Bank appropriated to bad debt reserves and deducted for
Federal income tax purposes are not available for payment of cash dividends or
other distributions to stockholders without payment of taxes at the then current
tax rate by the Bank on the amount of earnings removed from the reserves for
such distributions.  See "Federal and State Taxation."  The Bank intends to make
full use of this favorable tax treatment and does not contemplate use of any
earnings in a manner which would limit the Bank's bad debt deduction or create
federal tax liabilities.

     Under FDIC regulation, the Bank is prohibited from making any capital
distributions if after making the distribution, the Bank would have: (i) a total
risk-based capital ratio of less than 8.0%; (ii) a Tier 1 risk-based capital
ratio of less than 4.0%; or (iii) a leverage ratio of less than 4.0%.

     DEPOSIT INSURANCE.  The Bank is assessed a premium by the FDIC for Bank
Insurance Fund ("BIF") insurance of its insurable deposit accounts.  The FDIC is
required to establish an assessment rate for deposit insurance premiums that
protects the insurance fund and considers the fund's operating expenses, case
resolution expenditures, income and the effect of the assessment rate on the
earnings and capital of BIF members.

                                       21
<PAGE>
 
     Under the FDIC's risk-based deposit insurance assessment system, the
assessment rate for an insured depository institution depends on the assessment
risk classification assigned to the institution by the FDIC, which is determined
by the institution's capital level and supervisory evaluations.  Based on the
data reported to regulators for the date closest to the last day of the seventh
month preceding the semi-annual assessment period, institutions are assigned to
one of three capital groups -- well capitalized, adequately capitalized or
undercapitalized -- using the same percentage criteria as in the prompt
corrective action regulations.  See "-- Prompt Corrective Regulatory Action."
Within each capital group, institutions are assigned to one of three subgroups
on the basis of supervisory evaluations by the institution's primary supervisory
authority and such other information as the FDIC determines to be relevant to
the institution's financial condition and the risk posed to the deposit
insurance fund.  Subgroup A consists of financially sound institutions with only
a few minor weaknesses.  Subgroup B consists of institutions that demonstrate
weaknesses which, if not corrected, could result in significant deterioration of
the institution and increased risk of loss to the deposit insurance fund.
Subgroup C consists of institutions that pose a substantial probability of loss
to the deposit insurance fund unless effective corrective action is taken.  As
of December 31, 1997, the Bank was assigned to Subgroup A.

     The BIF deposit insurance assessment rates are determined by the FDIC based
on a number of factors to maintain a statutory designated reserve ratio for the
BIF of 1.25% of insured deposits. In March 1997, the reserve ratio was above
this target ratio and the FDIC adjusted the BIF assessment rates so that "well-
capitalized" institutions in Subgroup A, numbering 95% of BIF-insured
institutions, including the Bank, would pay no federal deposit insurance
premiums, with the remaining 5% of institutions paying a graduated range of
rates up to 0.27% of insured deposits for the highest risk-based premium
category. These rates will be effective until the FDIC takes further action.

     In fiscal 1996, the FDIC imposed a one-time special assessment on SAIF-
insured institutions which required those institutions to pay a one time fee of
65 basis points based on their deposits at March 31, 1995. This special
assessment recapitalized the SAIF and as a result, the FDIC lowered the SAIF
deposit insurance assessment rates to a range from 0 to 0.31% of insured
deposits through the 1997 calendar year. In the past, the substantial disparity
existing between deposit insurance premiums paid by BIF and SAIF members, gave
the Bank a significant competitive advantage over SAIF institutions. The
reduction of SAIF deposit insurance premiums erased this disparity and could
have the effect of increasing net income of SAIF institutions and thereby
restoring the competitive equality between BIF-insured and SAIF-insured
institutions.

     The FDIC has issued a separate levy for the Financing Corporation (FICO) 
bonds.  All FDIC-insured institutions will have to make FICO payments,
but BIF-insured deposits will be assessed at only one-fifth of the rate of SAIF-
insured deposits until January 1, 2000, or sooner, if the two funds are merged.

     PROMPT CORRECTIVE REGULATORY ACTION.  FDICIA requires the federal banking
regulators to take prompt corrective action in the event an FDIC-insured
institution fails to meet certain minimum capital requirements.  Under FDICIA,
as implemented by regulations adopted by the FDIC, an institution is assigned to
one of the following five capital categories:

     .    well-capitalized -- total risk-based capital ratio of 10% or greater,
          Tier 1 risk-based capital ratio of 6% or greater, leverage ratio of 5%
          or greater, and no written FDIC directive or order requiring the
          maintenance of specific levels of capital;

     .    adequately capitalized -- total risk-based capital ratio of 8% or
          greater, Tier 1 risk-based capital ratio of 4% or greater, and
          leverage ratio of 4% or greater (or 3% or greater if the institution's
          composite rating under the FDIC's supervisory rating system is 1);

     .    undercapitalized -- total risk-based capital ratio of less than 8%, or
          Tier 1 risk-based capital ratio of less than 4%, or leverage ratio of
          less than 4% (or less than 3% if the institution's composite rating
          under the FDIC's supervisory rating system is 1);
      

                                       22
<PAGE>
 
     .    significantly undercapitalized -- total risk-based capital ratio of
          less than 6%, or Tier 1 risk-based capital ratio of less than 3% or
          leverage ratio of less than 3%; and

     .    critically undercapitalized -- ratio of tangible equity to total
          assets of 2% or less.

     Under FDICIA, an "undercapitalized institution" generally is: (i) subject
to increased monitoring by the appropriate federal banking regulator; (ii)
required to submit an acceptable capital restoration plan within 45 days; (iii)
subject to asset growth limits; and (iv) required to obtain prior regulatory
approval for acquisitions, branching and new lines of businesses.  A
significantly undercapitalized institution, as well as any undercapitalized
institution that does not submit an acceptable capital restoration plan, may be
subject to regulatory demands for recapitalization, broader application of
restrictions on transactions with affiliates, limitations on interest rates paid
on deposits, restrictions on asset growth and other activities, possible
replacement of directors and officers, and restrictions on capital distributions
by any bank holding company controlling the institution.  Any company
controlling the institution may also be required to divest the institution.  The
senior executive officers of such an institution may not receive bonuses or
increases in compensation without prior approval and the institution is
prohibited from making payments of principal or interest on its subordinated
debt, with certain exceptions.  If an institution's ratio of tangible capital to
total assets falls below a level established by the appropriate federal banking
regulator, which may not be less than 2% of total assets nor more than 65% of
the minimum tangible capital level otherwise required (the "critical capital
level"), the institution is subject to conservatorship or receivership within 90
days unless periodic determinations are made that forbearance from such action
would better protect the deposit insurance fund.  Unless appropriate findings
and certifications are made by the appropriate federal bank regulatory agencies,
a critically undercapitalized institution must be placed in receivership if it
remains critically undercapitalized on average during the calendar quarter
beginning 270 days after the date it became critically undercapitalized.  At
December 31, 1997, the Bank was classified as "well capitalized" under the
FDIC's regulations.

     STANDARDS FOR SAFETY AND SOUNDNESS.  Under FDICIA, as amended by the Riegle
Community Development and Regulatory Improvement Act of 1994 (the "CDRI Act"),
each Federal banking agency is required to establish safety and soundness
standards for institutions under its authority.  On July 10, 1995, the federal
banking agencies released Interagency Guidelines Establishing Standards for
Safety and Soundness and published a final rule establishing deadlines for
submission and review of safety and soundness compliance plans.  The final rule
and the guidelines went into effect on August 9, 1995.  The guidelines require
depository institutions to maintain internal controls and information systems
and internal audit systems that are appropriate for the size, nature and scope
of the institution's business.  The guidelines also establish certain basic
standards for loan documentation, credit underwriting, interest rate risk
exposure, and asset growth.  The guidelines further provide that depository
institutions should maintain safeguards to prevent the payment of compensation,
fees and benefits that are excessive or that could lead to material financial
loss, and should take into account factors such as comparable compensation
practices at comparable institutions.  If the appropriate federal banking agency
determines that a depository institution is not in compliance with the safety
and soundness guidelines, it may require the institution to submit an acceptable
plan to achieve compliance with the guidelines.  A depository institution must
submit an acceptable compliance plan to its primary federal regulator within 30
days of receipt of a request for such a plan.  Failure to submit or implement a
compliance plan may subject the institution to regulatory sanctions.  Management
believes that the Bank already meets substantially all the standards adopted in
the interagency guidelines, and therefore does not believe that implementation
of these regulatory standards will materially affect the operations of the Bank.


     UNIFORM LENDING STANDARDS.  As required by FDICIA, the federal banking
agencies adopted regulations effective March 19, 1993 that require banks to
adopt and maintain written policies establishing appropriate limits and
standards for extensions of credit that are secured by liens or interests in
real estate or are made for the purpose of financing permanent improvements to
real estate.  These policies must establish loan portfolio diversification
standards, prudent underwriting standards, including loan-to-value limits, that
are clear and measurable, loan administration procedures and documentation,
approval and reporting requirements.  A bank's real estate lending policy must
reflect consideration of the Interagency Guidelines for Real Estate Lending
Policies (the "Interagency Guidelines") that have 

                                       23
<PAGE>
 
been adopted by the banking agencies. The Interagency Guidelines, among other
things, call upon depository institutions to establish internal loan-to-value
limits for real estate loans that are not in excess of the loan-to-value limits
specified in the Guidelines for the various types of real estate loans. The
Interagency Guidelines state, however, that it may be appropriate in individual
cases to originate or purchase loans with loan-to-value ratios in excess of the
supervisory loan-to-value limits. The Bank does not believe that the Interagency
Guidelines will materially affect its lending activities.

     FEDERAL RESERVE SYSTEM.  Pursuant to regulations of the Federal Reserve
Board, all FDIC-insured depository institutions must maintain average daily
reserves against their transaction accounts.  The Bank must maintain reserves
equal to 3% on the first $47.8 million of transaction accounts, and a reserve of
10% must be maintained against all remaining transaction accounts.  These
reserve requirements are subject to adjustment by the Federal Reserve Board.
Because required reserves must be maintained in the form of vault cash or in a
noninterest bearing account at a Federal Reserve Bank, the effect of the reserve
requirement is to reduce the amount of the institution's interest-earning
assets.  At December 31, 1997, the Bank met its reserve requirements.

     FEDERAL HOME LOAN BANK SYSTEM.  The Bank is a member of the Federal Home
Loan Bank System ("FHLBS") which consists of 12 regional Federal Home Loan Banks
governed and regulated by the Federal Housing Finance Board ("FHFB") of the
Federal Home Loan Bank Board.  As a member, the Bank is required to purchase and
hold stock in the FHLB of Boston in an amount equal to the greater of 1% of
their aggregate unpaid home loan balances at the beginning of the year or an
amount equal to 5% of FHLB advances outstanding or 1% of 30% of total assets,
whichever is higher.  As of December 31, 1997, the Bank held stock in the FHLB
of Boston in the amount of $3.7 million and was in compliance with the above
requirement.

     The FHLB of Boston serves as a reserve or central bank for the member
institutions within its assigned region.  It is funded primarily from proceeds
derived from the sale of consolidated obligations of FHLBS.  It makes loans
(i.e., advances) to members in accordance with policies and procedures
established by the FHLBS and the Board of Directors of the FHLB of Boston.

     MASSACHUSETTS STATE LAW.  As a state-chartered co-operative bank, the Bank
is subject to the applicable provisions of Massachusetts law and the regulations
of the Commissioner adopted thereunder.  The Bank derives its lending and
investment powers from these laws, and is subject to periodic examination and
reporting requirements by and of the Commissioner.  In addition, it is required
to make periodic reports to the Central Bank.  In 1990, legislation was enacted
permitting banks nationwide to enter the Bank's market area and compete for
deposits and loan originations.  The approval of the Massachusetts Commissioner
of Banks is required prior to any merger or consolidation, or the establishment
or relocation of any office facility.

REGULATION AND SUPERVISION OF THE COMPANY

     GENERAL.  The Company is a bank holding company within the meaning of the
Bank Holding Company Act of 1956, as amended, (the "BHCA").  As such, the
Company is registered with the Federal Reserve Board and subject to Federal
Reserve Board regulation, examination, supervision and reporting requirements.
As a bank holding company, the Company is required to furnish to the Federal
Reserve Board annual and quarterly reports of its operations at the end of each
period and to furnish such additional information as the Federal Reserve Board
may require pursuant to the BHCA.  The Company is also subject to regular
examination by the Federal Reserve Board.

     Under the BHCA, a bank holding company must obtain the prior approval of
the Federal Reserve Board before (i) acquiring direct or indirect ownership or
control of any voting shares of any bank or bank holding company if, after such
acquisition, the bank holding company would directly or indirectly own or
control more than 5% of such shares; (ii) acquiring all or substantially all of
the assets of another bank or bank holding company; or (iii) merging or
consolidating with another bank holding company.

     Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994.
Effective September 29, 1995, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Riegle-Neal Act") allows the Federal Reserve Board
to approve an application of an adequately capitalized and adequately managed
bank holding company to acquire control of, or acquire all or substantially all
of the assets of, a bank located in a state other than such holding company's
home state, without regard to whether the transaction is prohibited by the laws
of any state.  The Federal Reserve Board may not approve the acquisition of bank
that has not been in existence for the minimum time period (not exceeding five
years) specified by the statutory law of the host state.  The Riegle-Neal Act
also prohibits the Federal Reserve Board from approving an application if the
applicant (and its depository institution affiliates) controls or would control
more than 10% of the insured deposits in the United States or 30% or more of the
deposits in the target bank's home state or in any state in which the target
bank maintains a branch.  The Riegle-Neal Act does not affect the authority of
states to limit the percentage of total insured deposits in the state which may
be held or controlled by a bank or bank holding company to the extent such
limitation does not discriminate against out-of-state banks or bank holding
companies.  Individual states may also waive the 30% state-wide concentration
limit contained in the Riegle-Neal Act.

     Additionally, the federal banking agencies are authorized to approve
interstate merger transactions without regard to whether such transaction is
prohibited by the law of any state, unless the home state of one of the banks
has opted out of the Riegle-Neal Act by adopting a law after the date of
enactment of the Riegle-Neal Act and prior to June 1, 1997 which applies equally
to all out-of-state banks and expressly prohibits merger transactions involving
out-of-state banks.  Interstate acquisitions of branches are permitted only if
the law of the state in which the branch is located permits such acquisitions.
Interstate mergers and branch acquisitions are also subject to the nationwide
and statewide insured deposit concentration amounts described above.

     The Riegle-Neal Act authorizes the OCC and FDIC to approve interstate
branching de novo by national and state banks, respectively, only in states
which specifically allow for such branching.  The Riegle-Neal Act also requires
the appropriate federal banking agencies to prescribe regulations which prohibit
any out-of-state bank from using the interstate branching authority primarily
for the purpose of deposit production.

     The BHCA also prohibits, with certain exceptions, a bank holding company
from acquiring direct or indirect ownership or control of more than 5% of the
voting shares of a company that is not a bank or a bank holding company, or from
engaging directly or indirectly in activities other than those of banking,
managing or controlling banks, or providing services for its subsidiaries.  The
principal exceptions to these prohibitions involve certain non-bank activities
which, by statute or by Federal Reserve Board regulation or order, have been
identified as activities closely related to the business of banking or managing
or controlling banks.  The activities of the Company are subject to these legal
and regulatory limitations under the BHCA and the Federal Reserve Board's
regulations thereunder.  Notwithstanding the Federal Reserve Board's prior
approval of specific nonbanking activities, the Federal Reserve Board has the
power to order a holding company or its subsidiaries to terminate any activity,
or to terminate its ownership or control of any subsidiary, when it has
reasonable cause to believe that the continuation of such activity or such
ownership or control constitutes a serious risk to the financial safety,
soundness or stability of any bank subsidiary of that holding company.

     CAPITAL ADEQUACY.  The Federal Reserve Board has adopted guidelines
regarding the capital adequacy of bank holding companies, which require bank
holding companies to maintain specified minimum ratios of capital to total
assets and capital to risk-weighted assets.  See "-- Regulation and Supervision
of the Bank -- Capital Requirements."

     DIVIDENDS AND DISTRIBUTIONS.  The Federal Reserve Board has the power to
prohibit dividends by bank holding companies if their actions constitute unsafe
or unsound practices.  The Federal Reserve Board has issued a policy statement
on the payment of cash dividends by bank holding companies, which expresses the
Federal Reserve Board's view that a bank holding company should pay cash
dividends only to the extent that the company's net income for the past year is
sufficient to cover both the cash dividends and a rate of earning retention that
is consistent with the company's capital needs, asset quality, and overall
financial condition.

                                       25
<PAGE>
 
     Bank holding companies are required to give the Federal Reserve Board
notice of any purchase or redemption of their outstanding equity securities if
the gross consideration for the purchase or redemption, when combined with the
net consideration paid for all such purchases or redemptions during the
preceding 12 months, is equal to 10% or more of the bank holding company's
consolidated net worth.  The Federal Reserve Board may disapprove such a
purchase or redemption if it determines that the proposal would violate any law,
regulation, Federal Reserve Board order, directive, or any condition imposed by,
or written agreement with, the Federal Reserve Board.  Bank holding companies
whose capital ratios exceed the thresholds for "well capitalized" banks on a
consolidated basis are exempt from the foregoing requirement if they were rated
composite 1 or 2 in their most recent inspection and are not the subject of any
unresolved supervisory issues.

FEDERAL AND STATE TAXATION

     FEDERAL TAXATION.  Thrift institutions such as the Bank are generally taxed
as corporations.  However, banks which meet certain definitional tests and other
conditions prescribed by the Internal Revenue Code of 1986, as amended (the
"Code") are allowed to establish a bad debt reserve and make annual additions
thereto which may be taken as a deduction in computing net taxable income for
federal income tax purposes.  The Bank elected to base its bad debt deduction on
the percentage of taxable income method for the year ended December 31, 1995.

     In August 1996, the provisions repealing the current thrift bad debt rules
were passed by Congress as part of "The Small Business Job Protection Act of
1996."  The new rules eliminate the 8% of taxable income method for deducting
additions to the tax bad debt reserves for all thrifts beginning after December
31, 1995.  These rules also require that all thrift institutions recapture all
or a portion of their bad debt reserves added since the base year (last taxable
year beginning before January 1, 1988).  The Bank has previously recorded a
deferred tax liability equal to the bad debt recapture and as such, the new
rules will have no effect on net income or federal income tax expense.  Tax
deductions for bad debts will now be calculated on the basis of actual
experience.

     The unrecaptured base year reserves will not be subject to recapture as
long as the institution continues to carry on the business of banking.  In
addition, the balance of the pre-1988 bad debt reserves continue to be subject
to provision of present law that require recapture in the case of certain excess
distributions to shareholders.  The tax effect of pre-1988 bad debt reserves
subject to recapture in the case of certain excess distributions is
approximately $2.3 million.

     Current and accumulated earnings and profits of the Bank (apart from
amounts appropriated to the bad debt reserve), to the extent otherwise
available, generally may be distributed as cash dividends without any federal
income tax being imposed on the Bank because of any such distribution.  However,
if income appropriated to the bad debt reserve and deducted for federal income
tax purposes is used or deemed to be used to pay cash dividends or other
distributions to stockholders, including distributions on redemption,
dissolution or liquidation, the Bank generally would be taxed at then current
corporate tax rates on approximately 151% of the amount that would be deemed
removed from such reserves by the Bank because of any such distribution.  As of
December 31, 1997, the Bank had approximately $5.4 million of tax bad debt
reserve for which federal income taxes have not been provided.

     STATE TAXATION.  On July 27, 1995, the Bank Tax Reform law enacted by the
Commonwealth of Massachusetts reduced the income tax rate for co-operative banks
and other financial institutions.  The rate reduction will be phased in over
four years beginning in 1995 and result in a reduction of the income tax rate to
10.5% of Federal taxable income adjusted by certain items.  Taxable income
includes income from all sources, without exclusion, less deductions, but not
the credits, allowable under the provisions of the Code, as amended.  No
deductions however, are allowed for dividends received or state income taxes.
In addition, carryforwards and carrybacks of net operating losses are not
allowed.  For 1997, the Massachusetts income tax rate was 11.32%.

                                       26
<PAGE>
 
     The Bank's subsidiaries, Sandwich Securities Corporation and Sextant
Securities Corporation, are investment companies that have been classified as
securities corporations under the provision of the General Laws of Massachusetts
and, as such, are subject to state taxes at a rate of 1.32% of gross receipts.

     Reference is made to Note 10 Notes to Consolidated Financial Statements for
additional information regarding income taxes.

COMPETITION

     The Bank's competition for deposits has historically come from other co-
operative banks, savings banks, savings and loan associations, trust companies,
commercial banks and credit unions located in Massachusetts generally, and on
Cape Cod specifically, some of which have greater financial resources than the
Bank. Based upon FDIC data for branch deposits as of June 30, 1997, the Bank
ranked fourth in total deposits in its principle market of Barnstable County
(Cape Cod), when compared to other deposit gathering institutions. The Bank has
also experienced significant additional competition for investors' funds from
short term money market funds, mutual funds, annuities and other corporate and
government securities yielding interest rates which have been higher than those
being paid by the Bank on savings deposits or containing other favorable
features. The Bank anticipates that it will face continuing competition from
other financial intermediaries for deposits.

     The Bank competes for deposits principally by offering depositors a wide
variety of checking, savings and investment programs, convenient branch
locations, 24-hour automated teller machine access, preauthorized payment and
withdrawal systems, tax-deferred retirement programs, and other miscellaneous
services. The Bank does not rely upon any individual, group or entity for a
material portion of its deposits.

     The Bank's competition for real estate loans comes principally from
mortgage banking companies, co-operative banks and savings banks, savings and
loan associations, commercial banks, insurance companies and other institutional
lenders. The Bank competes for loan originations primarily through the interest
rates and loan fees it charges and the efficiency and quality of services it
provides borrowers, real estate brokers and builders. For 1997, Banker and
                                                                ----------

mortgages on Cape Cod (Barnstable County), Massachusetts, by dollar amount. The
competition for loans encountered by the Bank, as well as the types of
institutions with which the Bank competes, varies from time to time depending
upon certain factors including the general availability of lendable funds and
credit, general and local economic conditions, current interest rate levels,
volatility in the mortgage markets and other factors which are not readily
predictable.

     In addition to competing with other banks and financial services
organizations based in Massachusetts, the Bank has and is expected to face
competition from major commercial banks headquartered outside of Massachusetts
as a result of regional interstate banking laws which currently permit banks
located in New England to enter the Bank's market area and compete with it for
deposits and loan originations. The Bank also faces increased competition as a
result of the Riegle-Neal Interstate Banking and Branching Efficiency Act of
1994 which, as of September 29, 1995, allowed the Federal Reserve Board to
approve a bank holding company's application to acquire control of, or
substantially all of the assets of, a Massachusetts bank without regard to
Massachusetts law.

     Bank regulation is undergoing significant change with an increased number
of bank mergers and acquisitions, changes in the products and services banks can
offer, and involvement in non-banking activities by bank holding companies.
There are a number of pending legislative and regulatory proposals that may
further alter the structure, regulation, and competitive relationships of
financial institutions.

     The Bank is headquartered in Sandwich, Massachusetts and operates a network
of eleven full service offices and one loan production office. The Bank's eleven
full service office facilities are located in Sandwich, South Sandwich, Buzzards
Bay (Bourne), Pocasset (Bourne), Wareham, Cedarville (Plymouth), Falmouth,
Hyannis, Chatham, Orleans

                                       27

and South Yarmouth, Massachusetts. The Bank's main office is located at 100 Old
Kings Highway, Sandwich, Massachusetts. In addition, the Bank maintains a loan
production office located in Plymouth, Massachusetts. Nine of the offices are
located on Cape Cod in Barnstable County, while the Wareham and Cedarville
offices are located in Plymouth County. The Bank's primary market area within
which the majority of the properties securing loans originated by the Bank are
located, encompasses the southern portion of Plymouth County and all of Cape Cod
(Barnstable County), Massachusetts.

EMPLOYEES

     As of December 31, 1997, the Company and subsidiaries had 128 full-time and
39 part-time employees. The employees are not represented by any collective
bargaining agreement. Management considers its relations with its employees to
be good.

</TABLE>

     The following is a description of the principal occupation and employment
of the executive officers of the Company during at least the past five years:

     DANA S. BRIGGS joined the Bank in 1983 as Assistant Vice President and Main
Office Manager and in 1984 became the Bank's Vice President of Administration.
Presently as Senior Vice President and Senior Retail/Operations Officer, he is

Mr. Briggs was employed by Bass River Savings Bank and Barnstable County
National Bank.

     GEORGE L. LARSON started with the Bank in November 1986 as Senior Vice
President and Chief Financial Officer and is responsible for the Financial
Division of the Bank. Mr. Larson came to the Bank with 15 years of bank
accounting and finance experience. From 1978 to 1986, Mr. Larson was employed by
Jefferson Federal Savings and Loan Association in Meriden, CT, as Senior Vice
President and Treasurer, in which capacities he was in charge of the Jefferson
Federal's accounting and data processing operations and managed the
Association's investment portfolio.

     DAVID A. PARSONS joined the Bank in December, 1990 as Senior Vice
President, Senior Loan Officer and is responsible for the Bank's Lending
Division. He was employed from 1969-1989 by Shawmut Bank. His career has covered
consumer lending and collection, commercial loan collection and workouts and
equipment financing & leasing. In 1989, Mr. Parsons was employed as an Executive
Vice President/Senior Credit Officer at Home National Bank in Milford,
Massachusetts. Upon Home National's closing, Mr. Parsons was employed by the
FDIC until August 1990. From August 1990 until being hired full-time by the Bank
in December 1990, Mr. Parsons was employed as a consultant to the Bank.

ITEM 2.  PROPERTIES.
- ------------------- 

     The Bank owns the Pocasset, Falmouth, Hyannis, Chatham and Orleans offices,
and the loan servicing office in Sandwich. The Bank leases the main office,
and the Buzzard Bay, Wareham, South Sandwich and South Yarmouth offices.
Management believes that the properties are in adequate condition to conduct the
Bank's business. In December 1997, the Bank entered into a sale/leaseback
agreement for three of its offices (main office, Buzzards Bay and Wareham) for
$1,738,000. The initial lease term is twenty years followed by four five-year 
renewal options. Furthermore, the Bank will have the right to re-purchase the
properties at the end of years eight, fifteen and twenty.

     The following table sets forth the location of the Bank's offices, as
well as certain information relating to these offices as of December 31, 1997:

          and "Proposal I -- Election of Directors" in the Proxy Statement.

     (c)  Changes In Control

          On February 2, 1998, the Company and the Bank entered into a
          definitive agreement under which Compass Bank of New Bedford,
          Massachusetts will acquire Sandwich Bancorp, Inc. Prior to the
          Company's consideration and approval of its definitive agreement with
          Compass Bank, the Company had contacted and received expressions of
          interest from three other parties who had expressed an interest in an
          acquisition of the Company.

          On February 24, 1998, the Company announced that its Board of
          Directors, consistent with the exercise of its fiduciary duties,
          determined that it was appropriate to request additional information
          and clarification of the renewed expressions of interest that it had
          received from three other parties subsequent to February 2.

          Following a comprehensive review of the other expressions of interests
          for the Company, the Company and Compass Bank jointly announces on
          March 23, 1998, that they have signed an amendment to their previously
          announced agreement of February 2, 1998 (the "Amended Agreement") by
          which Compass Bank would acquire Sandwich Bancorp, Inc. Under the
          terms of the Amended Agreement, Compass Bank's parent company, The
          1855 Bancorp will convert to a 100% publicly owned stock holding
          company and thereafter issue stock having a value of $64.00 per share
          to Sandwich Bancorp shareholders in a tax-free exchange of common
          stock. The value to be received by Sandwich Bancorp shareholders is
          subject to adjustment pursuant to a formula based on the value of the
          stock of The 1855 Bancorp near the transaction date. Based on 1855
          Bancorp's assumed initial public offering price of $10.00 per share,
          each Sandwich Bancorp share will be exchanged for 1855 Bancorp stock
          having a value of $64.00 per share so long as 1855 Bancorp stock
          trades at an average price of between $10.00 and $13.50 per share
          during a designated trading period following the initial public
          offering date. If this average price exceeds $13.50 per share, the
          value to be received by Sandwich Bancorp shareholders will increase
          proportionately up to a maximum value of $71.11 until 1855 Bancorp's
          average price reaches or exceeds $15.00 per share. If this average
          price is equal to or less than $10.00 per share, Sandwich Bancorp
          shares will be exchanged for 6.4 shares of 1855 Bancorp stock.

          Sandwich Bancorp and The 1855 Bancorp also entered into a Stock Option
          Agreement, granting to The 1855 Bancorp an option to acquire up to
          19.9% of Sandwich common stock under certain circumstances. The
          transaction, which is subject to all necessary regulatory and
          shareholder approvals, is expected to close in the fourth quarter of
          1998.

          In connection with the Merger, the directors of the Company have
          agreed to enter into a separate letter agreement with The 1855 Bancorp
          (the "Company Letter Agreements") in which such director generally
          agrees, among other things, to vote their individual shares of Company
          common stock for approval of the Amended Agreement.

          For additional information, reference is made to the Amended and
          Restated Affiliation and Merger Agreement, dated as of March 23, 1998,
          attached hereto as Exhibit 2.1, and the Stock Option Agreement dated
          as of March 23, 1998, attached hereto as Exhibit 2.2.

                                  ARTICLE III

                             CONVERSION OF SHARES

     3.1  CONVERSION SHARES.  At the Effective Time, by virtue of the Merger and
without any action on the part of Merger Sub, Sandwich or the holders of any of
the shares of Sandwich Common Stock (shares of Sandwich Common Stock being
hereinafter collectively referred to as "Shares"):
                                         ------   

          3.1.1  Each Share issued and outstanding immediately prior to the
Effective Time (other than any Shares to be cancelled pursuant to Section 312
and any Dissenting Shares (as hereinafter defined)) shall be cancelled and shall
be converted automatically into the right to receive an amount equal to $53.00
in cash for each Share (the "Fixed Consideration").  In the event that the
                             -------------------                          
Effective Time has not occurred on or prior to October 1, 1998, and the failure
of the Effective Time to have occurred on or prior to such anniversary is not
primarily attributable to acts or omissions by or circumstances related to
Sandwich, then the Fixed Consideration shall be adjusted upwards by an amount
determined by (A) multiplying (1) the Fixed Consideration by (2) a percentage
interest rate determined for the period commencing on the day after October 1,
1998, through and including the 

                                       6
<PAGE>
 
Effective Date (the "Measurement Period") by averaging the discount rate,
expressed as a percentage, from face value on the [90-DAY TREASURY BILL RATE]
for the initial and each succeeding seven-day period (or portion thereof) during
the Measurement Period based on the most recent auction of such 90-day treasury
bill as reported in the "Money Rates" column of The Wall Street Journal or
                                                ----------------------- 
equivalent publication or information service, rounded at the date the foregoing
calculation is made at the Effective Time, upwards to the nearest $.01, then (B)
dividing the product determined pursuant to clause (A) by 365, and then (C)
multiplying the amount obtained after the application of clauses (A) and (B) by
the number of calendar days in the Measurement Period. The Fixed Consideration,
to the extent adjusted as provided above, is referred to herein as the "Merger
                                                                        ------
Consideration".
- --------------

          3.1.2  Each Share held in the treasury of Sandwich and each Share
owned by Merger Sub, 1855 Bancorp or any direct or indirect wholly owned
subsidiary of 1855 Bancorp or of Sandwich immediately prior to the Effective
Time shall be cancelled without any conversion thereof and no payment or
distribution shall be made with respect thereto.

          3.1.3  Each share of the common stock of Merger Sub issued and
outstanding immediately prior to the Effective Time shall be converted into and
exchanged for one validly issued, fully paid and nonassessable share of the
common stock of the Surviving Corporation.

     3.2  EMPLOYEE STOCK OPTIONS.  Prior to the Effective Time, Sandwich shall,
in accordance with the terms of the Sandwich Option Plans, provide written
notice to each holder of a then outstanding stock option to purchase Shares
pursuant to the Sandwich Option Plans (whether or not such stock option is then
vested or exercisable), that such stock option shall be, as at the date of such
notice, exercisable in full and that such stock option will be automatically
canceled at the Effective Time and that, if such stock option is not exercised
or otherwise terminated before the Effective Time, such holder shall be entitled
to receive in cancellation of such option a cash payment from Sandwich at the
Closing in an amount equal to the excess of the Merger Consideration over the
per share exercise price of such stock option, multiplied by the number of
Shares covered by such stock option, subject to any required withholding of
taxes.  Subject to the foregoing, the Sandwich Option Plans and all options
issued thereunder shall terminate at the Effective Time.  Sandwich hereby
represents and warrants to 1855 Bancorp that the maximum number of Shares
subject to issuance pursuant to the exercise of stock options issued and
outstanding under the Sandwich Option Plans is not and shall not be at or prior
to the Effective Time more than 144,778.

     3.3  DISSENTING SHARES.

          3.3.1  Notwithstanding anything in this Agreement to the contrary and
unless otherwise provided by applicable law, Shares that are issued and
outstanding immediately prior to the Effective Time and that are owned by
stockholders who have properly perfected their rights of appraisal within the
meaning of Section 85 of Chapter 156B of the Massachusetts General Laws (the
                                                                            
"Dissenting Shares"), shall not be converted into the right to receive the
- ------------------                                                        
Merger Consideration, unless and until such stockholders shall have failed to
perfect or shall have effectively withdrawn or lost their right of payment under
applicable law, but, instead, the holders thereof shall be entitled to payment
of the appraised value of such Dissenting Shares in accordance with the
provisions of the Massachusetts General Laws, Chapter 156B (S) 85 et seq.  If
                                                                  -- ----    
any such holder shall have failed to perfect or shall have effectively withdrawn
or lost such right of appraisal, each Share held by such stockholder shall
thereupon be deemed to have been converted into the right to receive and become
exchangeable for, at the Effective Time, the Merger Consideration in the manner
provided in Section 28 hereof.

          3.3.2  Sandwich shall give 1855 Bancorp (i) prompt notice of any
objections filed pursuant to Massachusetts General Laws, Chapter 156B, (S) 85 et
                                                                              --
seq., received by Sandwich, withdrawals of
- ---
                                       7
<PAGE>
 
such objections, and any other instruments served in connection with such
objections pursuant to the Massachusetts General Laws and received by Sandwich
and (ii) the opportunity to direct all negotiations and proceedings with respect
to objections under the Massachusetts General Laws consistent with the
obligations of Sandwich thereunder. Sandwich shall not, except with the prior
written consent of 1855 Bancorp, (x) make any payment with respect to any such
objection, (y) offer to settle or settle any such objections or (z) waive any
failure to timely deliver a written objection in accordance with the
Massachusetts General Laws.

     3.4  SURRENDER OF SHARES; STOCK TRANSFER BOOKS.

          3.4.1  Prior to the Effective Time, 1855 Bancorp or Compass Bank shall
designate a bank or trust company, reasonably acceptable to Sandwich, to act as
agent (the "Paying Agent") for the holders of Shares in connection with the
            ------------                                                   
Merger to receive the funds to which holders of Shares shall become entitled
pursuant to Section 311.  Immediately prior to the Effective Time, Compass Bank
shall deposit, or cause to be deposited, with the Paying Agent, for the benefit
of the holders of certificates evidencing such Shares (the "Certificates"), for
                                                            ------------       
exchange in accordance with this Article III, such amount of cash as is
sufficient to pay the aggregate Merger Consideration which holders of Shares are
entitled to receive in exchange for outstanding Shares.

          3.4.2  Promptly after the Effective Time (but in no event more than
three business days thereafter), 1855 Bancorp and Compass Bank shall cause to be
mailed to each person who was, at the Effective Time, a holder of record of
Shares entitled to receive the Merger Consideration a form of letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Paying Agent) and instructions for use in effecting the
surrender of the Certificates pursuant to such letter of transmittal. Sandwich
shall have the right to review the letter of transmittal, the instructions and
any accompanying letter. Upon surrender to the Paying Agent of a Certificate,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, and such other documents as may be
required pursuant to such instructions, the holder of such Certificate shall be
entitled to receive in exchange therefor the Merger Consideration for each Share
formerly evidenced by such Certificate, and such Certificate shall then be
cancelled. No interest shall accrue or be paid for the period following the
Effective Time on the Merger Consideration payable upon the surrender of any
Certificate for the benefit of the holder of such Certificate. If payment of the
Merger Consideration is to be made to a person other than the person in whose
name the surrendered Certificate is registered on the stock transfer books of
Sandwich, it shall be a condition of payment that the Certificate so surrendered
shall be endorsed properly or otherwise be in proper form for transfer and that
the person requesting such payment shall have paid all transfer and other taxes
required by reason of the payment of the Merger Consideration to a person other
than the registered holder of the Certificate surrendered or shall have
established to the satisfaction of the Surviving Corporation that such taxes
either have been paid or are not applicable.

          3.4.3  At any time following the twelfth month after the Effective
Time, 1855 Bancorp or Compass Bank shall be entitled to require the Paying Agent
to deliver to it any funds which had been made available to the Paying Agent and
not disbursed to holders of Shares (including, without limitation, all interest
and other income received by the Paying Agent in respect of all funds made
available to it), and thereafter such holders shall be entitled to look to 1855
Bancorp and Compass Bank (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 1855 Bancorp nor Compass Bank nor
the Paying 

                                       8
<PAGE>
 
Agent shall be liable to any holder of a Share for any Merger Consideration
delivered in respect of such Share to a public official pursuant to any
abandoned property, escheat or other similar law.

          3.4.4  At the close of business on the Effective Date, the stock
transfer books of Sandwich shall be closed and thereafter there shall be no
further registration of transfers of Shares on the records of Sandwich. From and
after the Effective Time, the holders of Shares outstanding immediately prior to
the Effective Time shall cease to have any rights with respect to such Shares
except as otherwise provided herein or by applicable law.

          3.4.5  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 1855
Bancorp or Compass Bank, upon the posting by such person of a bond in such
amount as 1855 Bancorp or Compass Bank may reasonably direct as indemnity
against any claim that may be made against it with respect to such Certificate,
the Paying Agent will issue in exchange for such lost, stolen or destroyed
Certificate, the cash representing the Merger Consideration deliverable in
respect thereof pursuant to this Agreement.

permits, licenses, certificates of authority, orders and approvals of, and has
made all filings, applications and registrations with, federal, state, local and
foreign governmental or regulatory bodies that are required in order to permit

of which could

                                       13
<PAGE>
 
reasonably be expected to have a Material Adverse Effect on Sandwich; all such
permits, licenses, certificates of authority, orders and approvals are in full
force and effect; and to the best knowledge of Sandwich, no suspension or
cancellation of any of the same is threatened.

           4.12.2  Neither Sandwich nor a Sandwich Subsidiary is in violation of
its respective Articles of Organization, Charter or Bylaws, or of any applicable

limitation, all banking (including without limitation all regulatory capital
requirements), securities, municipal securities, safety, health, environmental,
zoning, anti-discrimination, antitrust, and wage and hour laws, ordinances,
orders, rules and regulations), or in default with respect to any order, writ,
injunction or decree of any court, or in default under any order, license,
regulation or demand of any governmental agency, any of which violations or
defaults could reasonably be expected to have a Material Adverse Effect on
Sandwich; and neither Sandwich nor a Sandwich Subsidiary has received any notice
or communication from any federal, state or local governmental authority
asserting that Sandwich or a Sandwich Subsidiary is in violation of any of the
foregoing which could reasonably be expected to have a Material Adverse Effect

any regulatory or supervisory cease and desist order, agreement, written
directive, memorandum of understanding or written commitment (other than those
of general applicability to all banks and holding companies thereof), and
neither of them has received any written communication requesting that it enter

considered by such shareholders will comply as to form in all material respects
with the Exchange Act and the rules and regulations promulgated thereunder.

           4.14.1  Sandwich has Previously Disclosed all stock option, employee
stock purchase and stock bonus plans, qualified pension or profit-sharing plans,
any deferred compensation, consultant, bonus or group insurance contract or any
other incentive, health and welfare or employee benefit plan or agreement
maintained for the benefit of employees or former employees of Sandwich or any
Sandwich Subsidiary (the "Sandwich Employee Plans"), whether written or oral,
and Sandwich has previously furnished or made available to 1855 Bancorp accurate

<PAGE>
 
plans, (ii) the most recent annual reports filed with any governmental agency,
and (iii) all rulings and determination letters and any open requests for
rulings or letters that pertain to any qualified plan.

           4.14.2  None of Sandwich, any Sandwich Subsidiary, any pension plan
maintained by either of them and qualified under Section 401 of the Code or, to
the best of Sandwich's knowledge, any fiduciary of such plan has incurred any
material liability to the PBGC or the Internal Revenue Service with respect to
any employees of Sandwich or a Sandwich Subsidiary.  To the best of Sandwich's
knowledge, no reportable event under Section 4043(b) of ERISA has occurred with
respect to any such pension plan.

           4.14.3  Neither Sandwich nor any Sandwich Subsidiary participates in
or has incurred any liability under Section 4201 of ERISA for a complete or
partial withdrawal from a multi-employer plan (as such term is defined in
ERISA).

           4.14.5  A favorable determination letter has been issued by the
Internal Revenue Service with respect to each Sandwich Employee Plan which is an
"employee pension benefit plan" (as defined in Section 3(2) of ERISA) (a
"Sandwich Pension Plan") which is intended to qualify under Section 401 of the
Code to the effect that such plan is qualified under Section 401 of the Code and
the trust associated with such employee pension plan is tax exempt under Section
501 of the Code. No such letter has been revoked or, to the best of Sandwich's
knowledge, is threatened to be revoked and Sandwich does not know of any ground
on which such revocation may be based. Neither Sandwich nor any Sandwich
Subsidiary has any liability under any such plan that is not reflected on the
consolidated statement of financial condition of Sandwich at December 31, 1997
included in the Sandwich Financial Statements, other than liabilities incurred
in the ordinary course of business in connection therewith subsequent to the
date thereof.

           4.14.5  To the best of Sandwich's knowledge, no prohibited
transaction (which shall mean any transaction prohibited by Section 406 of ERISA
and not exempt under Section 408 of ERISA or Section 4975 of the Code) has
occurred with respect to any Sandwich Employee Plan which would result in the
imposition, directly or indirectly, of a material excise tax under Section 4975
of the Code or otherwise have a Material Adverse Effect on Sandwich.

           4.14.6  Full payment has been made (or proper accruals have been
established) of all contributions which are required for periods prior to the
date hereof, and full payment will be so made (or proper accruals will be so
established) of all contributions which are required for periods after the date
hereof and prior to the Effective Time, under the terms of each Sandwich
Employee Plan or ERISA; to the best of Sandwich's knowledge, no accumulated
funding deficiency (as defined in Section 302 of ERISA or Section 412 of the
Code), whether or not waived, exists with respect to any Sandwich Pension Plan,
and there is no "unfunded current liability" (as defined in Section 412 of the
Code) with respect to any Sandwich Pension Plan.

           4.14.7  To the best of Sandwich's knowledge, the Sandwich Employee
Plans have been operated in compliance in all material respects with the
applicable provisions of ERISA, the Code, all regulations, rulings and
announcements promulgated or issued thereunder and all other applicable
governmental laws and regulations.

           4.14.8  There are no pending or, to the best knowledge of Sandwich,
threatened claims (other than routine claims for benefits) by, on behalf of or
against any of the Sandwich Employee Plans or any trust related thereto or any
fiduciary thereof.

           4.14.9  Neither Sandwich nor 1855 Bancorp will be required to make a
Pension Payment as a result of the Merger.  The term "Pension Payment" shall
                                                      ---------------

                                       15

Sandwich or its successor is or would be liable to the Co-operative Banks
Employees Retirement Association in connection with the cessation of Sandwich's
participation in said Association's pension plan and its complete withdrawal
from said pension plan.

     customer for the provision of banking services entered into by any Sandwich
     Subsidiary in the ordinary course of business) that involves a payment or

or by which its assets, business or operations may be bound or affected, whether

or oral, and there has not occurred any event that with the lapse of time or the
giving of notice, or both, would constitute such a material default or non-
compliance.

maintained all insurance required by applicable laws and regulations.  Sandwich

<PAGE>
 
           (p)  knowingly take any action that would result in the
     representations and warranties of Sandwich contained in this Agreement not
     being true and correct on the date of this Agreement or at any future
     date on or prior to the Closing Date; or

           (q)  agree to do any of the foregoing.

     6.2  CURRENT INFORMATION.  During the period from the date of this
Agreement to the Effective Time, Sandwich will cause one or more of its
representatives to confer with representatives of 1855 Bancorp and report the
general status of its ongoing operations at such times as 1855 Bancorp may
reasonably request.  Sandwich will promptly notify 1855 Bancorp of any material
change in the normal course of its business or in the operation of its
properties and, to the extent permitted by applicable law, of any governmental
complaints, investigations or hearings (or communications indicating that the
same may be contemplated), or the institution or the threat of material
litigation involving Sandwich. Sandwich will also provide 1855 Bancorp such
information with respect to such events as 1855 Bancorp may reasonably request
from time to time.  As soon as reasonably available, but in no event more than
45 days after the end of each calendar quarter ending after the date of this
Agreement (other than the last quarter of each fiscal year ending December 31),
the Sandwich will deliver to 1855 Bancorp its quarterly report on Form 10-Q
under the Exchange Act, and, as soon as reasonably available, but in no event

liabilities, including, but not limited to, all books of account (including the
general ledger), tax records, minute books of directors' and stockholders'
meetings, organizational documents, by-laws, material contracts and agreements,
filings with any regulatory authority, litigation files, plans affecting
employees, and any other business activities or prospects in which 1855 Bancorp
may have a reasonable interest; provided, however, that Sandwich shall not be
required to take any action that would provide access to or to disclose
information where such access or disclosure would violate or prejudice the
rights or business interests or confidences of any customer or other person or
would result in the waiver by it of the privilege protecting communications
between it and any of its counsel.  Sandwich shall provide and shall request its
auditors to provide 1855 Bancorp with such historical financial information
regarding it (and related audit reports and consents) as 1855 Bancorp may
reasonably request for securities disclosure purposes.

     6.4  FINANCIAL AND OTHER STATEMENTS.

        6.4.1  Promptly upon receipt thereof, Sandwich will furnish to 1855

all internal control reports submitted to Sandwich by such accountants in
connection with each annual, interim or special audit of the books of Sandwich
and the Sandwich Subsidiaries made by such accountants.

        6.4.2  As soon as practicable, Sandwich will furnish to 1855 Bancorp

                                       28
<PAGE>
 
        6.4.3  Sandwich will advise 1855 Bancorp promptly of the receipt of any
examination report of any federal or state regulatory or examination authority
with respect to the condition or activities of Sandwich or any of the Sandwich
Subsidiaries.

        6.4.2  With reasonable promptness, Sandwich will furnish to 1855 Bancorp
such additional financial data as 1855 Bancorp may reasonably request, including
without limitation, detailed monthly financial statements and loan reports.

     6.5  DISCLOSURE SUPPLEMENTS.  From time to time prior to the Effective
Time, Sandwich will promptly supplement or amend the Disclosure Schedules
delivered in connection herewith pursuant to Article IV with respect to any
material matter hereafter arising which, if existing, occurring or known at the
date of this Agreement, would have been required to be set forth or described in
such Disclosure Schedules or which is necessary to correct any information in
such Schedules which has been rendered inaccurate thereby.  No supplement or
amendment to such Schedules shall have any effect for the purpose of determining
satisfaction of the conditions set forth in Article IX.

     6.6  CONSENTS AND APPROVALS OF THIRD PARTIES.  Sandwich shall use all
reasonable efforts to obtain as soon as practicable all consents and approvals
of any other Persons necessary or desirable for the consummation of the
transactions contemplated by this Agreement.  Without limiting the generality of
the foregoing, Sandwich shall utilize the services of a professional proxy
soliciting firm to help obtain the shareholder vote required to be obtained by
it hereunder.

     6.7  ALL REASONABLE EFFORTS.  Subject to the terms and conditions herein
provided, Sandwich agrees to use all reasonable efforts to take, or cause to be
taken, all corporate or other action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement.

     6.8  FAILURE TO FULFILL CONDITIONS.  In the event that Sandwich determines
that a condition to its obligation to complete the Merger cannot be fulfilled
and that it will not waive that condition, it will promptly notify 1855 Bancorp.

     6.9  NO SOLICITATION.  Unless and until this Agreement shall have been
properly terminated by either party pursuant to Section 111 hereof, neither
Sandwich nor any of its subsidiaries shall (and Sandwich and Sandwich Bank shall
use all commercially reasonable efforts to cause its representatives, including,
but not limited to, investment bankers, attorneys and accountants, not to),
directly or indirectly, encourage, solicit, initiate or participate in any
discussions or negotiations with, or, provide any information to, any
corporation, partnership, person or other entity or group (other than 1855
Bancorp and its affiliates or Representatives) concerning any merger, tender
offer, sale of substantial assets, sale of shares of capital stock or debt
securities or similar transaction involving Sandwich or Sandwich Bank (an
"Acquisition Transaction"); provided, however that Sandwich and its
- ------------------------                                           
representatives shall be permitted to participate in discussions or negotiations
with, or provide information to, any other corporation, partnership, person or
other entity or group with respect to an Acquisition Transaction if the Board of
Directors of Sandwich determines (in good faith upon the advice of outside
counsel) that their fiduciary duties require them to do so.  Notwithstanding the
foregoing, nothing contained in this Section 69 shall prohibit Sandwich or its
Board of Directors from taking and disclosing to Sandwich's stockholders a
position with respect to a tender offer by a third party pursuant to Rules 14d-9
and 14e-2(a) promulgated under the Exchange Act or from making such disclosure
to Sandwich's stockholders which, in the judgment of the Board of Directors
(upon the advice of counsel), may be required under applicable law or is
necessary in order to comply with its fiduciary obligations. Sandwich will
immediately communicate to 1855 Bancorp the terms of any proposal, discussion,
negotiation or inquiry relating to an Acquisition Transaction and the identity
of the party making such 

                                       29
<PAGE>
 
proposal or inquiry which it may receive in respect of any such transaction
(which shall mean that any such communication shall be delivered no less
promptly than by telephone within 24 hours of Sandwich's receipt of any such
proposal or inquiry) or its receipt of any request for information from the FRB,
the DOJ, or any other governmental agency or authority with respect to a
proposed Acquisition Transaction. Sandwich shall continue to consult with 1855
Bancorp after receipt of such proposal or commencement of such discussion or
negotiation relating to an Acquisition Transaction, and will not take any action
with respect to such proposed Acquisition Transaction except after reasonable
consultation with 1855 Bancorp.

                                  ARTICLE VII

any necessary approvals of governmental authorities required for the
transactions contemplated hereby or materially increase the period of time
necessary to obtain such approvals, or (ii) materially adversely affect its
ability to perform its covenants and agreements under this Agreement, or (iii)
result in the representations and warranties of 1855 Bancorp contained in this
Agreement not being true and correct on the date of this Agreement or at any

     7.2  CURRENT INFORMATION.  During the period from the date of this
Agreement to the Effective Time, 1855 Bancorp will cause one or more of its

     7.8  FAILURE TO FULFILL CONDITIONS.  In the event that 1855 Bancorp

Effective Time shall become employees of 1855 Bancorp or an 1855 Bancorp
Subsidiary as of the Effective Time. Nothing in this Agreement shall give any
employee of Sandwich or its Subsidiaries a right to continuing employment with
1855 Bancorp or any Subsidiary thereof after the Effective Time. Any employee of
Sandwich or any Sandwich Subsidiary whose employment with 1855 Bancorp or any
1855 Bancorp Subsidiary is terminated by 1855 Bancorp within one year after the
Effective Time shall be entitled to receive (i) a lump-sum severance benefit in
an amount equal to two-weeks' pay for each year of employment (with

                                       31
<PAGE>
 
partial years of service included in the calculation on a pro-rated basis), up
to a maximum of 26 weeks' pay, and (ii) continuation of health benefits, on the
same terms and conditions applicable to 1855 Bancorp's active employees, for the
same number of weeks factored into the calculation of severance payments, and
thereafter COBRA benefits for an additional period of time determined as though
the Sandwich employee terminates employment upon expiration of the period
covered by said continued health benefits.

shall provide or cause to be provided to all employees of Sandwich and any
Sandwich Subsidiary who remain employed by 1855 Bancorp or any 1855 Bancorp
Subsidiary after the Effective Time with employee benefits which, in the
aggregate, are no less favorable than those generally afforded to other
employees of 1855 Bancorp or the 1855 Bancorp Subsidiaries holding similar
positions, subject to the terms and conditions under which those employee
benefits are made available to such employees, provided, however, that (i) for
purposes of determining eligibility for and vesting of such employee benefits
only (and not for pension benefit accrual purposes), service with Sandwich or
any Sandwich Subsidiary prior to the Effective Time shall be treated as service
with an "employer" as if such persons had been employees of 1855 Bancorp, to the
extent permissible under the terms of 1855 Bancorp's Employee Plans, (ii) this
Section 79 shall not be construed to limit the ability of 1855 Bancorp and its
Subsidiaries to terminate the employment of any employee or to review employee
benefits programs from time to time and to make such changes as they deem
appropriate, and (iii) 1855 Bancorp or a Subsidiary shall continue to provide
post-retirement medical benefits to former employees of Sandwich who as of the
Effective Time are receiving post-retirement medical benefits in accordance with
Sandwich's Previously Disclosed retiree health care Plans I, II, and III, (iv)
1855 Bancorp shall honor any and all vacation leave (but not sick leave) accrued
by Sandwich's employees, except to the extent of any duplication of benefits,
and (v) no preexisting condition exclusion that is currently inapplicable to a
Sandwich employee and/or the employee's covered dependents shall affect their
rights to health benefits or coverage under 1855 Bancorp's plans, to the extent
permissible under such plans.

employment and change of control agreements, deferred compensation plans,
Grantor Trust Agreement, Supplemental Retirement Plans and Split Dollar
Insurance Agreements (collectively, "Benefit Agreements"). Following the
Effective Time, 1855 Bancorp shall honor or cause its Subsidiaries to honor in
accordance with their terms all such Previously Disclosed Benefit Agreements and
assume or cause its Subsidiaries to assume all duties, liabilities and
obligations under such agreements and  arrangements. 1855 Bancorp agrees that
(i) the consummation of the transactions contemplated hereby constitutes a
"Change in Control" as defined in the Benefit Agreements, and (ii) each of
Sandwich's officers who is party to an employment agreement with Sandwich will
be deemed to have suffered a material change in their responsibilities and
supervision as of the Effective Time, it being understood that the President of
Sandwich shall terminate employment as of the Effective Time and receive
payments under Section 11(a) of his Employment at such time.

in the Employee Stock Ownership Plan shall have the right to transfer their
distributions into any tax-qualified defined contribution plan that 1855 Bancorp
maintains, but only if and to the extent that such plan accepts rollover

     7.10  DIRECTORS AND OFFICERS INDEMNIFICATION AND INSURANCE.

          7.10.1  1855 Bancorp shall maintain, or shall cause Compass Bank to
maintain, in effect for six years from the Effective Time, if available, the
current directors' and officers' liability insurance policies maintained by
Sandwich (provided, that 1855 Bancorp may substitute therefor policies of at
least the same coverage containing terms and conditions which are not materially
less favorable) with respect to matters occurring prior to the Effective Time;
provided, however, that in no event shall 1855 Bancorp be required to expend
pursuant to this Section 7.10.1 more than $60,000 in the aggregate.  In 
connection with the foregoing, Sandwich agrees to provide such insurer or 
substitute insurer with such representations as such insurer may request with 
respect to the reporting of any prior claims.

          7.10.2  From and after the Effective Time, 1855 Bancorp shall, or
shall cause Compass Bank to, indemnify, defend and hold harmless each person who
is now, or who has been at any time before the date hereof or who becomes before
the Effective Time, an officer or director of Sandwich or the Sandwich
Subsidiaries or any of their respective subsidiaries (the "Indemnified Parties")
against all losses, claims, damages, costs, expenses (including attorney's
fees), liabilities or judgments or amounts that are paid in settlement (which
settlement shall require the prior written consent of 1855 Bancorp, which
consent shall not be unreasonably withheld) of or in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal, or
administrative (each a "Claim"), in which an Indemnified Party is, or is
threatened to be made, a party or witness in whole or in part on or arising in
whole or in part out of the fact that such person is or was a director, officer
or employee of Sandwich or any of its subsidiaries if such Claim pertains to any
matter of fact arising, existing or occurring before the Effective Time
(including, without limitation, the Merger and the other transactions
contemplated hereby), regardless of whether such Claim is asserted or claimed
before, or at or after, the Effective Time (the "Indemnified Liabilities"), to
the fullest extent permitted under applicable state or federal law in effect as
of the date hereof or as amended applicable to a time before the Effective Time
and under Sandwich's and Sandwich Bank's Articles of Organization or Charter and
By-Laws. 1855 Bancorp shall pay expenses in advance of the final disposition of
any such action or proceeding to each Indemnified Party to the full extent
permitted by applicable state or federal law in effect as of the date hereof or
as amended applicable to a time before the Effective Time upon receipt of an
undertaking to repay such advance payments if he shall be adjudicated or
determined to be not entitled to indemnification in the manner set forth below.
Any Indemnified Party wishing to claim indemnification under this Section 7.10.2
upon learning of any Claim, shall notify 1855 Bancorp (but the failure so to
notify 1855 Bancorp shall not relieve it from any liability which it may have
under this Section 7.10.2, except to the extent such failure materially
prejudices 1855 Bancorp) and shall deliver to 1855 Bancorp the undertaking
referred to in the previous sentence. In the event of any such Claim (whether
arising before or after the Effective Time) (1) 1855 Bancorp shall have the
right to assume the defense thereof (in which event the Indemnified Parties will
cooperate in the defense of any such matter) and upon such assumption 1855
Bancorp shall not be liable to any Indemnified Party for any legal expenses of
other counsel or any other expenses subsequently incurred by any Indemnified
Party in connection with the defense thereof, except that if 1855 Bancorp elects
not to assume such defense, or counsel for the Indemnified Parties reasonably
advises the Indemnified Parties that there are or may be (whether or not any
have yet actually arisen) issues which raise conflicts of interest between 1855
Bancorp and the Indemnified Parties, the Indemnified Parties may retain counsel
reasonably satisfactory to them, and 1855 Bancorp shall pay the reasonable fees
and expenses of such counsel for the Indemnified Parties, (2) 1855 Bancorp shall
be obligated pursuant to this paragraph to pay for only one firm of counsel for
all Indemnified Parties whose reasonable fees and expenses shall be paid
promptly as statements are received, (3) 1855 Bancorp shall not be liable for
any settlement effected without its prior written consent (which consent shall
not be unreasonably withheld) and (4) no Indemnified Party  

                                       33
<PAGE>
 
shall be entitled to indemnification hereunder with respect to a matter as to
which (x) he shall have been adjudicated in any proceeding not to have acted in
good faith in the reasonable belief that his action was in the best interests of
Sandwich or any Subsidiary, or (y) in the event that a proceeding is compromised
or settled so as to impose any liability or obligation upon an Indemnified
Party, if there is a determination that with respect to said matter said
Indemnified Party did not act in good faith in the reasonable belief that his
action was in the best interests of Sandwich or any Subsidiary. The
determination shall be made by a majority vote of the trustees of 1855 Bancorp
who were formerly directors of Sandwich and who are not involved in such
proceeding (the "Former Sandwich Directors"), or, if a majority of the Former
Sandwich Directors are involved in the proceeding, by a committee of three
disinterested Former Sandwich Directors chosen by all of the Former Sandwich
Directors for the purpose of making such determination.

          7.10.3  In the event that either 1855 Bancorp or Compass Bank or any
of its successors or assigns (i) consolidates with or merges into any other
person and shall not be the continuing or surviving bank or entity of such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each such case, proper
provision shall be made so that the successors and assigns of 1855 Bancorp shall
assume the obligations set forth in this Section 7.10.

          7.10.4  The obligations of 1855 Bancorp provided under this Section
7.10 are intended to be enforceable against 1855 Bancorp directly by the
Indemnified Parties and shall be binding on all respective successors and
permitted assigns of 1855 Bancorp.

     7.11  MERGER SUB.  Prior to the Effective Time, 1855 Bancorp will take any
and all necessary action to cause (i) Merger Sub to be organized, (ii) Merger
Sub to become a direct or indirect wholly-owned subsidiary of 1855 Bancorp,
(iii) the directors and stockholder or stockholders of Merger Sub to approve the
transactions contemplated by this Agreement, and (iv) Merger Sub to execute one
or more counterparts of this Agreement and to deliver at least one such
counterpart so executed to Sandwich, whereupon Merger Sub shall become a party
to and be bound by this Agreement.

                         REGULATORY AND OTHER MATTERS

     8.1  SANDWICH SPECIAL MEETING.  Sandwich will (i) as promptly as
practicable, take all steps necessary to duly call, give notice of, convene and

as may be, in Sandwich's reasonable judgment, necessary or desirable, (ii)
subject to the fiduciary responsibility of the Board of Directors of Sandwich as
advised by counsel, recommend to its stockholders the approval of the

each other in the preparation of the Sandwich Proxy Statement; 1855 Bancorp
shall provide Sandwich with any information concerning it that Sandwich may
reasonably request in connection with the Proxy Statement and Sandwich shall
notify 1855 Bancorp promptly of the receipt of any comments of the SEC with
respect to the Sandwich Proxy Statement and of any requests by the SEC for any
amendment or supplement thereto or for additional information and shall provide

                                       34
<PAGE>
 
opportunity to review all amendments and supplements to the Sandwich Proxy
Statement and all responses to requests for additional information and replies
to comments prior to their being filed with, or sent to, the SEC. Each of 1855
Bancorp and Sandwich agrees to use all reasonable efforts, after consultation
with the other party hereto, to respond promptly to all such comments of and
requests by the SEC and to cause the Sandwich Proxy Statement and all required
amendments and supplements thereto to be mailed to the holders of Sandwich
Common Stock entitled to vote at the Sandwich Stockholders Meeting referred to
in Section 8.1 hereof at the earliest practicable time. 1855 Bancorp shall
promptly notify Sandwich if at any time it becomes aware that the Proxy
Statement 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, Sandwich and 1855 Bancorp shall cooperate in the
preparation of a supplement or amendment to such Proxy Statement which corrects
such misstatement or omission, and shall cause the same to be filed with the SEC
and to be mailed to Sandwich's stockholders.

     8.3  CAPITAL OFFERING.  Commencing promptly after the date of this
Agreement, 1855 Bancorp and Compass Bank will take all reasonable steps
necessary to effect the Capital Offering and 1855 Bancorp shall use its best
efforts to satisfy the conditions to closing set forth in Section 9.2.5
(provided that in no event shall 1855 Bancorp or Compass Bank (or the Mid-Tier
Subsidiary) be required to undertake a full conversion to stock form or
otherwise issue more than 49% of its capital stock).  If the Capital Offering is
to be effected through the Mid-Tier Holding Company, such steps shall include,
without limitation, organizing the Mid-Tier Holding Company as a newly-created
subsidiary of 1855 Bancorp and contributing all of the capital stock of Compass
Bank to the Mid-Tier Holding Company. In addition, without limiting the
generality of the foregoing, 1855 Bancorp shall cause the following to be done:

          8.3.1  1855 Bancorp shall duly call, give notice of, convene and hold
a special meeting of its Board of Corporators as soon as practicable for the
purpose of approving the Capital Offering. The Board of Trustees of 1855 Bancorp

          8.3.2  Compass Bank will use all reasonable efforts to prepare and
file all required regulatory applications required in connection with the

is effected through the Mid-Tier Holding Company).

          8.3.3  1855 Bancorp shall prepare as promptly as practicable, and
Sandwich shall co-operate in the preparation of, a prospectus or offering
circular (the "Offering Document") meeting all requirements of applicable
federal and state securities and banking laws and regulations. If the Capital
Offering is to be effected through the Mid-Tier Holding Company, 1855 Bancorp
shall incorporate such Offering Document into a Form S-1 Registration Statement
("Form S-1") satisfying all applicable requirements of the Securities Act, and
the rules and regulations thereunder, and shall use its reasonable best efforts
to have the Form S-1 declared effective under the Securities Act as promptly as
practicable after such filing.

          8.3.4  Sandwich shall provide 1855 Bancorp with any information
concerning it that 1855 Bancorp may reasonably request in connection with the
Offering Document, and Sandwich shall promptly notify 1855 Bancorp if at any
time it becomes aware that the Offering Document or the Form S-1 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, Sandwich and 1855 Bancorp shall cooperate in the preparation of a
supplement or amendment to such Offering Document, which corrects such misstate-

                                       35
<PAGE>
 
ment or omission, and shall cause an amended Form S-1 to be filed with the SEC
(if applicable). Sandwich shall provide to 1855 Bancorp a "comfort" letter from
the independent certified public accountants for Sandwich, dated as of the date
of the Offering Document and updated as of the date of consummation of the
Capital Offering, with respect to certain financial information regarding
Sandwich, each in form and substance which is customary in transactions such as
the Capital Offering, and shall cause its counsel to deliver to the placement
agent for the Capital Offering such opinions as 1855 Bancorp may reasonably
request.

          8.3.5  1855 Bancorp shall give Sandwich and its counsel the
opportunity to review the Offering Document prior to its being filed with the
Bank Commissioner and FDIC (and the SEC, if applicable) and shall give Sandwich
and its counsel the opportunity to review all amendments and supplements to the
Offering Document and all responses to requests for additional information and
replies to comments prior to their being filed with, or sent to, the Bank
Commissioner, the FDIC (and the SEC, if applicable). Each of 1855 Bancorp and
Sandwich agrees to use all reasonable efforts, after consultation with the other
party hereto, to respond promptly to all such comments of and requests by the
Bank Commissioner, FDIC and the SEC and to cause the Offering Document and all
required amendments and supplements thereto to be mailed to the qualified
depositors of Compass Bank at the earliest practicable time.

     8.4  REGULATORY APPROVALS. Each of Sandwich and 1855 Bancorp will cooperate
with the other and use all reasonable efforts to promptly prepare all necessary
documentation, to 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, including without limitation the Merger, the Bank Merger and
the Capital Offering. Sandwich and 1855 Bancorp 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 Offering Document, the Proxy Statement and
any application, petition or any other statement or application made by or on
behalf of Sandwich or 1855 Bancorp to any governmental body in connection with
the Capital Offering, the Merger, the Bank Merger, and the other transactions
contemplated by this Agreement. Sandwich and 1855 Bancorp shall have the right
to review and approve in advance all characterizations of the information
relating to 1855 Bancorp or Sandwich, as the case may be, and 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, Sandwich and 1855 Bancorp shall each furnish to the other for review a
copy of each such filing made in connection with the transactions contemplated
by this Agreement with any governmental body prior to its filing.

     negligence by a party hereto) shall be without liability, cost or expense
     on the part of any party to the other.

               (b)  In the event of a termination of this Agreement pursuant to
     Section 11.1.2 or 11.1.3 hereof resulting from the willful conduct or gross
     negligence of a party, such party shall be obligated to reimburse the other

     without limitation, reasonable legal, accounting and investment banking
     fees and expenses, incurred by such other party in connection with the

     of Costs 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 or as is
     contemplated herein. Notwithstanding anything to the contrary herein, if
     (i) Sandwich makes the payment contemplated in Section 11.4 of this
     Agreement or (ii) if 1855 Bancorp makes the payment 

                                       40
<PAGE>
 
     contemplated in Section 113 of this Agreement, such party shall not have
     any further liability to the other party (or its Subsidiaries), whether for
     Costs, breach or otherwise.

          11.2.3  Except as provided in Sections 11.2.2, 11.3 and 11.4, whether
or not the Merger is consummated, all Costs incurred in connection with this
Agreement and the transactions contemplated hereby shall be borne by the party
incurring such costs and expenses.

          11.2.4  In no event shall any officer, agent or director of Sandwich,
any Sandwich Subsidiary, 1855 Bancorp or any 1855 Bancorp Subsidiary, be
personally liable thereunder for any default by any party in any of its
obligations hereunder unless any such default was intentionally caused by such
officer, agent or director.

     11.3 1855 BANCORP SPECIAL PAYMENT.  As a condition of Sandwich's
willingness to, and in order to induce Sandwich to, enter into this Agreement,
and to reimburse Sandwich for incurring the damages, costs and expenses related
to entering into this Agreement and consummating the transactions contemplated
by this Agreement, 1855 Bancorp hereby agrees to pay to Sandwich, as liquidated
damages and in lieu of any other rights or remedies under this Agreement, a
payment in the amount of $4,000,000 (the "Special Payment") if and only if (i)

the Merger is not consummated and the Agreement is terminated in accordance with
its terms due to the failure of the condition set forth in Section 9.2.5 of this
Agreement, or (ii) the Agreement is terminated pursuant to Section 11.1.7, or
(iii) 1855 Bancorp otherwise does not consummate the Capital Offering by no
later than December 31, 1998 (subject to the two month extension contemplated in
Section 11.1.4 herein), or (iv) Sandwich has terminated this Agreement in
accordance with Section 11.1.2 or 11.1.3 because 1855 Bancorp has intentionally
or willfully breached any of its representations or warranties herein or
intentionally and willfully failed to perform or comply with any of its
covenants or agreements herein, to such extent as to permit such termination
(such reasons for termination being hereinafter referred to as the "Special
                                                                    -------

(subject to the standard set forth in Section 1112 of this Agreement) or a
breach by Sandwich one or more covenants in this Agreement (subject to the
standard set forth in Section 1113 of this Agreement), which breach of

contrary set forth in this Agreement, if 1855 Bancorp pays or causes to be paid
to Sandwich the Special Payment, neither 1855 Bancorp nor Compass Bank will have
any further obligations or liabilities to Sandwich or Sandwich Bank with respect
to this Agreement or the transactions contemplated by this Agreement.

     11.4 SANDWICH CHANGE IN CONTROL EXPENSE FEE. As a condition of 1855
Bancorp's willingness to, and in order to induce 1855 Bancorp to, enter into
this Agreement, and to reimburse 1855 Bancorp for incurring the damages, costs
and expenses related to entering into this Agreement and consummating the
transactions contemplated by this Agreement, Sandwich hereby agrees to pay to
1855 Bancorp, as liquidated damages, and in lieu of any other rights or remedies
under this Agreement, a payment in the amount of $4,000,000 (the "Expense Fee")
                                                                  -----------

     Control Transaction"); or

              (b) any person (other than 1855 Bancorp or any 1855 Bancorp
     Subsidiary) shall have acquired beneficial ownership (as such term is

              any representation, warranty, covenant or obligation contained in
              this Agreement and such breach would entitle 1855 Bancorp to
              terminate this Agreement under Section 11.1.2 or 11.1.3 hereof
              (without regard to the cure period provided for therein unless
              such cure is promptly effected without jeopardizing consummation

Notwithstanding any other provision of this Agreement, the provisions of this

                                     ----------------------------              
be the earliest to occur of:

              (a) The Effective Time of the Merger,

     following the occurrence of a Time Extension Event;

Section 11.4 shall be paid by Sandwich to 1855 Bancorp by wire transfer of
immediately available funds to an account designated by 1855 Bancorp within five

circumstances that would trigger a payment under this Section 11.4, the
standstill provisions contained in the Confidentiality Agreement shall
terminate.

          11.4.5  EXCLUSIVITY OF REMEDY. Notwithstanding anything to the
contrary set forth in this Agreement, if Sandwich pays or causes to be paid to
1855 Bancorp or to Compass Bank the Expense Fee, neither Sandwich nor Sandwich

of any other party hereto, (c) waive any inaccuracies in the representations and
warranties contained herein or in any document delivered pursuant hereto, or (d)

provided, however, that after any approval of this Agreement and the
transactions contemplated hereby by the stockholders of Sandwich, there may not
be, without further approval of such stockholders, any amendment of this
Agreement which reduces the amount or changes the form of consideration to be
delivered to Sandwich's stockholders pursuant to this Agreement. This Agreement
may not be amended except by an instrument in writing signed on behalf of each
of the parties hereto. 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.

                           FORM OF VOTING AGREEMENT



                                        February     , 1998


The 1855 Bancorp
[address]

Ladies and Gentlemen

     The undersigned is a director of Sandwich Bancorp ("Sandwich") and is the
beneficial holder of shares of common stock of Sandwich ("Sandwich Common
Stock").

     Sandwich and The 1855 Bancorp ("1855 Bancorp") are considering the
execution of an Affiliation and Merger Agreement ("Affiliation Agreement")
contemplating the merger of a newly formed special-purpose subsidiary  of
Compass Bank, a Massachusetts stock savings bank and wholly owned subsidiary of
1855 Bancorp, with and into Sandwich, with Sandwich as the surviving corporation
of the merger (the "Merger"), such execution being subject in the case of 1855
Bancorp to the execution and delivery of this letter agreement ("Agreement").
In consideration of the substantial expenses that 1855 Bancorp will incur in
connection with the transactions contemplated by the Affiliation Agreement and
in order to induce 1855 Bancorp to execute the Affiliation Agreement and to
proceed to incur such expenses, the undersigned agrees and undertakes, in his
capacity as a shareholder of Sandwich and not in his capacity as a director of
Sandwich, as follows:

     1. The undersigned will vote or cause to be voted for approval of the
Affiliation Agreement all of the shares of Sandwich Common Stock the undersigned
is entitled to vote with respect thereto.

     2. The undersigned will not effect any transfer or other disposition of any
of the undersigned's shares of Sandwich Common Stock until Sandwich's
shareholders have voted to approve the Affiliation Agreement or until the
Affiliation Agreement has been terminated pursuant to the terms thereof.  In the
case of any transfer by operation of law or otherwise, this Agreement shall be
binding upon and inure to the benefit of the transferee.  Any transfer or other
disposition in violation of the terms of this paragraph 2 shall be null and
void.

     3. The undersigned agrees that Sandwich's transfer agent shall be given an
appropriate stop transfer order and shall not be required to register any
attempted transfer of shares of Sandwich Common Stock, unless the transfer has
been effected in compliance with the terms of this Agreement.

     4. The undersigned acknowledges and agrees that any remedy at law for
breach of the foregoing provisions shall be inadequate and that, in addition to
any other relief which may be available, 1855 Bancorp shall be entitled to
temporary and permanent injunctive relief without the necessity of proving
actual damages.

     5. The foregoing restrictions shall not apply to shares with respect to
which the undersigned may have voting power as a fiduciary for others.  In
addition, this agreement shall only apply to actions taken by the undersigned in
his capacity as a shareholder of Sandwich and shall not in any way limit or
affect actions the undersigned may take in his capacity as a director of
Sandwich.

     IN WITNESS WHEREOF, the undersigned has executed this Agreement as of the
date first above written.

                                        Very truly yours,


                                        ________________________

        FORM OF OPINION OF HOUSLEY, KANTARIAN & BRONSTEIN, P.C./LOCAL 
                 COUNSEL REASONABLY ACCEPTABLE TO 1855 BANCORP


     (a)  Each of Sandwich Bancorp and Sandwich Bank is validly existing under
the laws of The Commonwealth of Massachusetts, and Sandwich Bancorp is duly
registered as a bank holding company under the BHCA.

     (b)  The authorized capital stock of Sandwich Bancorp consists of ______
shares of Sandwich Bancorp Common Stock and 10,000,000 shares of Sandwich
Bancorp Preferred Stock. All of the outstanding shares of Sandwich Bancorp
Common Stock have been duly authorized and are nonassessable, and the
shareholders of Sandwich Bancorp have no preemptive rights with respect to any
shares of capital stock of Sandwich Bancorp.  All of the outstanding shares of
capital stock of Sandwich Bank and each other Sandwich Subsidiary have been duly
authorized and are nonassessable, and, to the actual knowledge of such counsel,
are directly or indirectly owned by Sandwich Bancorp free and clear of all
liens, claims, encumbrances, charges, restrictions or rights of third parties of
any kind whatsoever.

     (c)  The Agreement has been duly authorized, executed and delivered by
Sandwich Bancorp and Sandwich Bank and, assuming due authorization, execution
and delivery by 1855 Bancorp and Compass Bank, constitutes a valid and binding
obligation of Sandwich Bancorp and Sandwich Bank enforceable in accordance with
its terms, except that the enforceability of the obligations of Sandwich Bancorp
and Sandwich Bank may be limited by (i) bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting the rights of creditors, (ii) equitable
principles limiting the right to obtain specific performance or other similar
equitable relief and (iii) considerations of public policy.

     (d)  Sandwich Bancorp and Sandwich Bank have all requisite corporate power
and authority to execute and deliver the Agreement and to consummate the Merger.
All corporate actions required to be taken by Sandwich Bancorp and Sandwich Bank
by law and their respective Charters and Bylaws to authorize the execution and
delivery of the Agreement and consummation of the Merger have been taken.

     (e)  All consents or approvals of or filings or registrations with any
federal or state banking agency which are necessary to be obtained by Sandwich
Bancorp and Sandwich Bank to permit the execution of the Agreement and
consummation of the Merger have been obtained.

     (f)  Neither the execution of the Agreement nor consummation of the Merger
will (i) conflict with or result in a breach of any provision of the Charter or
By-laws or similar governing instruments, of Sandwich Bancorp or any of its
Subsidiaries, (ii) constitute a breach of or default under, or give rise to a
right of termination, cancellation or acceleration with respect to, [specified
agreements listed in Disclosure Schedules] except as described in the Sandwich
Disclosure Schedule, or (iii) violate any Massachusetts banking or corporate law
or federal banking law of the United States binding upon Sandwich Bancorp or any
of its Subsidiaries, or any order, writ, injunction or decree of which we have
actual knowledge to which Sandwich Bancorp or any of its Subsidiaries, is
subject.

     (g)  We do not have actual knowledge of any actions, suits or proceedings
pending or threatened against Sandwich Bancorp or any Subsidiary, at law or in
equity, before any court or 

                                      -1-

governmental body which in any manner challenges or seeks to prevent, enjoin,
alter or materially delay consummation of the Merger.

     In rendering their opinion, such counsel may rely, to the extent such
counsel deems such reliance necessary or appropriate, upon certificates of
governmental officials,  certificates or opinions of other counsel to Sandwich
Bancorp or a Sandwich Bancorp Subsidiary reasonably satisfactory to 1855 Bancorp
and, as to matters of fact, certificates of officers of Sandwich Bancorp or a
Sandwich Bancorp Subsidiary.  The opinion of such counsel need refer only to
matters of Massachusetts and federal law and may add other qualifications and
explanations of the basis of their opinion as may be reasonably acceptable to
1855 Bancorp.

     Counsel may expressly exclude any opinions as to choice of law and anti-
trust matters and may add such other qualifications and explanations of the
basis of its opinions as are consistent with the Legal Opinion Accord prepared
by the Section of Business Law of the American Bar Association.

       (d)  If the 1855 Trading Price is $10.00 or less, the Exchange Ratio will
   be 6.4.

     3.1.2 For purposes of this Agreement, the "1855 Trading Price" shall be
determined by averaging the closing bid and asked price of the 1855 Common Stock
for each of the second through the ninth trading days (inclusive) following
consummation of the Conversion (the average of the closing bid and asked price
for each such day is referred to as the "Daily Closing Price"), discarding the
two highest and two lowest Daily Closing Prices, and averaging the remaining
Daily Closing Prices.  The closing bid and asked prices shall be as quoted at
the close of business on the Stock Exchange.

     3.1.3 The foregoing determination of the Exchange Ratio assumes that the 
initial public offering ("IPO") price of the 1855 Bancorp Common Stock in the
Conversion will be $10.00 per share. If the IPO price is an amount other than
$10.00, the Exchange Ratios and dollar amounts in Section 3.1.1 shall be
proportionately adjusted to reflect the actual IPO price.

     3.1.4 Shares of Sandwich Common Stock converted into 1855 Common Stock 
pursuant to this Section 3.1 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 Share shall thereafter 
         -----------
represent the right to receive (i) the number of whole shares of 1855 Common 
Stock and (ii) cash in lieu of fractional shares into which the Shares
represented by such Certificate have been converted pursuant to this Section 3.1
and Section 3.4 hereof (the "Merger Consideration").  Certificates previously 
                            --------------------
representing Shares of Sandwich Common Stock shall be exchanged for 
certificates representing whole shares of 1855 Common Stock and cash in lieu 
of fractional shares issued in consideration therefor upon the surrender of 
such Certificates in accordance with Section 3.4 hereof, without any interest 
thereon.

     3.1.5 Each Share held in the treasury of Sandwich and each Share owned by
Merger Sub, 1855 Bancorp or any direct or indirect wholly owned subsidiary of
1855 Bancorp or of Sandwich immediately prior to the Effective Time (other than
shares held in a fiduciary capacity or in connection with 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 and
no payment or distribution shall be made in consideration therefor.

     3.1.6 Each share of the common stock of Merger Sub issued and outstanding
immediately prior to the Effective Time shall be converted into and exchanged
for one validly issued, fully paid and nonassessable share of the common stock
of the Surviving Corporation.

     3.2 EMPLOYEE STOCK OPTIONS.  Prior to the Effective Time, Sandwich shall, 
in accordance with the terms of the Sandwich Option Plans, provide written 
notice to each holder of a then outstanding Sandwich Option (whether or not such
stock option is then vested or exercisable), that such Sandwich Option shall be,
as at the date of such notice, exercisable in full and that, if such Sandwich
Option is not exercised or otherwise terminated in accordance with its terms
before the Effective Time, such Sandwich Option shall, at the Effective Time, be
automatically converted into a number of shares of 1855 Common Stock determined
by application of the following formula, subject to any required withholding of
taxes:

                        [(MCV - EP) (divide)  TP] x OS

where:
  MCV =  Merger Consideration Value per share, determined by multiplying the 
         Exchange Ratio by the 1855 Trading Price
  EP  =  Exercise Price per share as stated in such Sandwich Option
  TP  =  1855 Trading Price, as determined in accordance with Section 3.1.2
  OS  =  Number of Option Shares covered by such Sandwich Option


Subject to the foregoing, the Sandwich Option Plans and all options issued
thereunder shall terminate at the Effective Time.  Sandwich hereby represents
and warrants to 1855 Bancorp that the maximum number of Shares subject to
issuance pursuant to the exercise of stock options issued and outstanding under
the Sandwich Option Plans is not and shall not be at or prior to the Effective
Time more than 143,778.

     3.3 DISSENTING SHARES.

     3.3.1 Notwithstanding anything in this Agreement to the contrary and unless
otherwise provided by applicable law, Shares that are issued and outstanding
immediately prior to the Effective Time and that are owned by stockholders who
have properly perfected their rights of appraisal within the meaning of Section
85 of Chapter 156B of the Massachusetts General Laws (the "Dissenting Shares"),
                                                           -----------------   
shall not be converted into the right to receive the Merger Consideration,
unless and until such stockholders shall have failed to perfect or shall have
effectively withdrawn or lost their right of payment under applicable law, but,
instead, the holders thereof shall be entitled to payment of the appraised value
of such Dissenting Shares in accordance with the provisions of the Massachusetts
General Laws, Chapter 156B (S) 85 et seq.  If any such holder shall have failed
                                  -- ----                                      
to perfect or shall have effectively withdrawn or lost such right of appraisal,
each Share held by such stockholder shall thereupon be deemed to have been
converted into the right to receive and become 


                                       8
<PAGE>
 
exchangeable for, at the Effective Time, the Merger Consideration in the manner
provided in Section 3.1 hereof.

     3.3.2 Sandwich shall give 1855 Bancorp (i) prompt notice of any objections
filed pursuant to Massachusetts General Laws, Chapter 156B, (S) 85 et seq.,
                                                                   ------  
received by Sandwich, withdrawals of such objections, and any other instruments
served in connection with such objections pursuant to the Massachusetts General
Laws and received by Sandwich and (ii) the opportunity to direct all
negotiations and proceedings with respect to objections under the Massachusetts
General Laws consistent with the obligations of Sandwich thereunder.  Sandwich
shall not, except with the prior written consent of 1855 Bancorp, (x) make any
payment with respect to any such objection, (y) offer to settle or settle any
such objections or (z) waive any failure to timely deliver a written objection
in accordance with the Massachusetts General Laws.

     3.4 PROCEDURES FOR EXCHANGE OF SANDWICH COMMON STOCK.

     3.4.1 1855 BANCORP TO MAKE SHARES AVAILABLE.  Prior to the Effective Time,
1855 Bancorp or Compass Bank shall designate a bank or trust company, reasonably
acceptable to Sandwich, to act as agent (the "Exchange Agent") for the holders
                                              --------------

Bancorp shall take all steps necessary on and as of the Effective Time to
deliver to the Exchange Agent, for the benefit of the holders of certificates
evidencing Shares ("Certificates"), for exchange in accordance with this Section
                    ------------                                                
3.4, certificates representing shares of 1855 Common Stock and the cash in lieu
of fractional shares to be paid pursuant to this Section 3.4 (such cash and
certificates for shares of 1855 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 Sandwich
- --------------                                                             
Common Stock in accordance with this Agreement.  The Exchange Agent shall act as
agent on behalf of record holders (individually, a "Record Holder") of Sandwich
                                                    -------------              
Common Stock at the Effective Time, other than Sandwich, any Sandwich
Subsidiary, 1855 Bancorp, or any 1855 Bancorp Subsidiary (in each case other
than in a fiduciary capacity or in connection with debts previously contracted),
or any Person holding Dissenting Shares.

     3.4.2 EXCHANGE OF CERTIFICATES.  Within three business days after the 
Effective Time, 1855 Bancorp 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 1855 Common Stock and the cash in lieu of fractional shares 
into which the Sandwich 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 Sandwich) 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 1855 Common Stock to which such holder of Sandwich Common Stock
shall have become entitled pursuant to the provisions of this Section 3.4 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 Certifi cates
surrendered pursuant to the provisions of this Section 3.4, and the Certificates
so surrendered shall forthwith be cancelled. Certificates surrendered for


                                       9
<PAGE>
 
exchange by any person who is an "affiliate" of Sandwich for purposes of Rule
145(c) under the Securities Act of 1933, as amended (the "Securities Act"),
                                                          --------------
shall not exchanged for certificates representing shares of 1855
Common Stock until Buyer has received the written agreement of such person
contemplated by Section 8.5 hereof.

     3.4.3 RIGHTS OF CERTIFICATE HOLDERS AFTER THE EFFECTIVE TIME.  The holder
of a Certificate that prior to the Merger represented issued and outstanding
Sandwich Common Stock shall have no rights, after the Effective Time, with
respect to such Sandwich 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 Massachusetts law. No
dividends or other distributions declared after the Effective Time with respect
to 1855 Common Stock shall be paid to the holder of any unsurrendered
Certificate until the holder thereof shall surrender such Certificate in
accordance with this Section 3.4. After the surrender of a Certificate in
accordance with this Section 3.4, the record holder thereof shall be entitled to
receive any such dividends or other distributions, without any interest thereon,
which theretofore had become payable with respect to shares of 1855 Common
Stock represented by such Certificate.

     3.4.4 FRACTIONAL SHARES.  Notwithstanding anything to the contrary 
contained herein, no certificates or scrip representing fractional shares of
1855 Common Stock shall be issued upon the surrender for exchange of
Certificates, no dividend or distribution with respect to 1855 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 other
rights of a stockholder of 1855 Bancorp. In lieu of the issuance of any such
fractional share, 1855 Bancorp shall pay to each former holder of Sandwich
Common Stock who otherwise would be entitled to receive a fractional share of
1855 Common Stock, an amount in cash determined by multiplying the closing sale
price of 1855 Common Stock on the Stock Exchange as reported by The Wall Street
Journal for the trading day immediately preceding the date of the Effective Time
(the "Last Closing Price") by the fraction of a share of 1855 Common Stock
      ------------------
which such holder would otherwise be entitled to receive pursuant to
Section 3.4.2 hereof. No interest will be paid on the cash which the holders of
such fractional shares shall be entitled to receive upon such delivery. For
purposes of determining any fractional share interest, all shares of Sandwich
Common Stock owned by a Sandwich shareholder shall be combined so as to
calculate the maximum number of whole shares of 1855 Bancorp Common Stock
issuable to such Sandwich shareholder.

     3.4.5 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.

     3.4.6 CLOSING OF TRANSFER BOOKS.  From and after the Effective Time, there
shall be 

                                       10
<PAGE>
 
no transfers on the stock transfer books of Sandwich of the Sandwich 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 Section 3.4.

     3.4.7 RETURN OF EXCHANGE FUND.  At any time following the 12-month period 
after the Effective Time, 1855 Bancorp 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 1855 Bancorp (subject to abandoned
property, escheat and other similar laws) with respect to any Merger
Consideration that may be payable upon due surrender of the Certificates held by
them. Notwithstanding the foregoing, neither 1855 Bancorp 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.

     3.4.8 LOST, STOLEN OR DESTROYED CERTIFICATES.  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 1855 Bancorp or Compass Bank, the posting by such
person of a bond in such amount as 1855 Bancorp 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.

     3.5 RESERVATION OF SHARES.  1855 Bancorp shall reserve for issuance a 
sufficient number of shares of 1855 Bancorp Common Stock for the purpose of
issuing shares of 1855 Bancorp Common Stock to the Sandwich shareholders and
optionholders in accordance with this Article III.

                   REPRESENTATIONS AND WARRANTIES OF SANDWICH

respect to any report or statement relating to any examinations of Sandwich or
any of the Sandwich Subsidiaries.

     4.13 CERTAIN INFORMATION.  None of the information relating to Sandwich 
and its Subsidiaries supplied or to be supplied for inclusion or incorporation

prospectus is mailed to subscribers (and at the time the related Form S-1 and
any amendments thereto become effective under the Securities Act), contain any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading, and (ii) the Proxy Statement-Prospectus, as of the

shareholders will comply as to form in all material respects with the Exchange
Act and the rules and regulations promulgated thereunder.

     4.14.1 Sandwich has Previously Disclosed all stock option, employee stock
purchase and stock bonus plans, qualified pension or profit-sharing plans, any
deferred compensation, consultant, bonus or group insurance contract or any
other incentive, health and welfare or employee benefit plan or agreement
maintained for the benefit of employees or former employees of Sandwich or any
Sandwich Subsidiary (the "Sandwich Employee Plans"), whether written or oral,

and complete copies of the same together with (i) the most recent actuarial and
financial reports prepared with respect to any qualified plans, (ii) the most
recent annual reports filed with any governmental agency, and (iii) all rulings
and determination letters and any open requests for rulings or letters that
pertain to any qualified plan.

     4.14.2  None of Sandwich, any Sandwich Subsidiary, any pension plan 
maintained by either of them and qualified under Section 401 of the Code or, to
the best of Sandwich's knowledge, any fiduciary of such plan has incurred any
material liability to the PBGC or the Internal Revenue Service with respect to
any employees of Sandwich or a Sandwich Subsidiary. To the best of Sandwich's
knowledge, no reportable event under Section 4043(b) of ERISA has occurred with
respect to any such pension plan.

                                       17
<PAGE>
 
 
     4.14.4 A favorable determination letter has been issued by the Internal 
Revenue Service with respect to each Sandwich Employee Plan which is an
"employee pension benefit plan" (as defined in Section 3(2) of ERISA) (a
"Sandwich Pension Plan") which is intended to qualify under Section 401 of the
Code to the effect that such plan is qualified under Section 401 of the Code and
the trust associated with such employee pension plan is tax exempt under Section
501 of the Code. No such letter has been revoked or, to the best of Sandwich's
knowledge, is threatened to be revoked and Sandwich does not know of any ground
on which such revocation may be based. Neither Sandwich nor any Sandwich
Subsidiary has any liability under any such plan that is not reflected on the
consolidated statement of financial condition of Sandwich at December 31, 1997
included in the Sandwich Financial Statements, other than liabilities incurred
in the ordinary course of business in connection therewith subsequent to the
date thereof.

     4.14.5 To the best of Sandwich's knowledge, no prohibited transaction 
(which shall mean any transaction prohibited by Section 406 of ERISA and not
exempt under Section 408 of ERISA or Section 4975 of the Code) has occurred with
respect to any Sandwich Employee Plan which would result in the imposition,
directly or indirectly, of a material excise tax under Section 4975 of the Code
or otherwise have a Material Adverse Effect on Sandwich.

     4.14.6 Full payment has been made (or proper accruals have been 
established) of all contributions which are required for periods prior to the
date hereof, and full payment will be so made (or proper accruals will be so
established) of all contributions which are required for periods after the date
hereof and prior to the Effective Time, under the terms of each Sandwich
Employee Plan or ERISA; to the best of Sandwich's knowledge, no accumulated
funding deficiency (as defined in Section 302 of ERISA or Section 412 of the
Code), whether or not waived, exists with respect to any Sandwich Pension Plan,
and there is no "unfunded current liability" (as defined in Section 412 of the
Code) with respect to any Sandwich Pension Plan.

     4.14.7 To the best of Sandwich's knowledge, the Sandwich Employee Plans 
have been operated in compliance in all material respects with the applicable
provisions of ERISA, the Code, all regulations, rulings and announcements
promulgated or issued thereunder and all other applicable governmental laws and
regulations.

     4.14.8 There are no pending or, to the best knowledge of Sandwich, 
threatened claims (other than routine claims for benefits) by, on behalf of or
against any of the Sandwich Employee Plans or any trust related thereto or any
fiduciary thereof.

     4.14.9 Neither Sandwich nor 1855 Bancorp will be required to make a Pension
Payment as a result of the Merger.  The term "Pension Payment" shall mean the
                                              ---------------                
amount, if any, for which Sandwich or its successor is or would be liable to the
Co-operative Banks Employees Retirement Association in connection with the
cessation of Sandwich's participation in said Association's pension plan and its
complete withdrawal from said pension plan.

Subsidiary is a party to, is bound or affected by, receives, or is obligated to

   transactions contemplated by this Agreement (either alone or in connection
   with the occurrence of any additional acts or events);

   Sandwich or a Sandwich Subsidiary is obligated to indemnify any director,

   the ordinary course of business) that involves a payment or series of 
   payments of more than $50,000 in any one year from or to Sandwich or any
   Sandwich Subsidiary (unless such agreement is cancellable by Sandwich upon
   payment of a termination fee of not more than $40,000), or

        (h)  any other agreement, arrangement or understanding which would be
   required to be filed as an exhibit to the Sandwich's Annual Report on Form
   10-K under the Exchange Act and which has not been so filed.

     4.15.2 Neither Sandwich nor any Sandwich Subsidiary is in material default
or non-compliance under any contract, agreement, commitment, arrangement, lease,
insurance policy or other instrument to which it is a party or by which its
assets, business or operations may be bound or affected, whether entered into in
the ordinary course of business or otherwise and whether written or oral, and
there has not occurred any event that with the lapse of time or the giving of
notice, or both, would constitute such a material default or non-compliance.

     4.16 BROKERS AND FINDERS.  Except as Previously Disclosed, neither 
Sandwich nor any Sandwich Subsidiary nor any of their respective directors,
officers or employees, has employed any broker or finder or incurred any

     4.17 INSURANCE.  Each of Sandwich and its Subsidiaries is insured for 
reasonable amounts with financially sound and reputable insurance companies
against such risks as companies engaged in a similar business would, in
accordance with good business practice, customarily be insured and has
maintained all insurance required by applicable laws and regulations. Sandwich
has Previously Disclosed all policies of insurance maintained by it or a
Sandwich Subsidiary as of the date hereof and any claims thereunder in excess of
$50,000 since January 1, 1995. Neither Sandwich nor any Sandwich Subsidiary has
received any notice of termination of any such insurance coverage or material
increase in the premiums therefor or has any reason to believe that any such
insurance coverage will be terminated or the premiums therefor materially
increased.

     4.18 LOAN PORTFOLIO.  Sandwich has Previously Disclosed all of the loans in
original principal amount in excess of $200,000 of Sandwich or any Sandwich
Subsidiary that as of the date of this Agreement are classified by Sandwich or
any Bank Regulator as "Special Mention", "Substandard", "Doubtful", "Loss" or
"Classified," together with the aggregate principal amount of and accrued and
unpaid interest on such all loans by category, it being understood that no
representation is being made that the FDIC, the Bank Commissioner or any other
Bank Regulator would agree with the loan classifications of Sandwich.

     4.19 PROPERTIES.  All real and personal property owned by Sandwich or its
Subsidiaries or presently used by any of them in its respective business is in
an adequate condition (ordinary wear and tear excepted) and is sufficient to
carry on the business of Sandwich and its Subsidiaries in the ordinary course of
business consistent with their past practices.  Sandwich has good and marketable
title free and clear of all liens, encumbrances, charges, defaults or equities
(other than equities of redemption under applicable foreclosure laws) to all of

respective terms and no such real property lease will terminate or lapse prior
to the Effective Time.

     4.20 LABOR.  No work stoppage involving Sandwich or a Sandwich Subsidiary 
is pending or, to the best knowledge of Sandwich, threatened. Neither Sandwich
nor a Sandwich Subsidiary is involved in, or threatened with or affected by, any
labor dispute, arbitration, lawsuit or administrative proceeding involving the
employees of Sandwich or a Sandwich Subsidiary which could have a Material
Adverse Effect on Sandwich.  Employees of Sandwich and the Sandwich Subsidiaries
are not represented by any labor union nor are any collective bargaining
agreements otherwise in effect with respect to such employees, and to the best
of Sandwich's knowledge, there have been no efforts to unionize or organize any
employees of Sandwich or any of the Sandwich Subsidiaries during the past five
years.

<PAGE>
 
 
     4.21.2 Assuming the accuracy of the representation and warranty of 1855 
Bancorp contained in Section 5.2.0 hereof, no "fair price," "moratorium,"

to this Agreement and the transactions contemplated hereby.

     4.22 MATERIAL INTERESTS OF CERTAIN PERSONS.  Except as Previously 
Disclosed, to the knowledge of Sandwich, no officer or director of Sandwich, or
any "associate" (as such term is defined in Rule 14a-1 under the Exchange Act)
of any such officer or director, (i) has any material interest in any material
contract or property (real or personal), tangible or intangible, used in or
pertaining to the business of Sandwich or any of the Sandwich Subsidiaries or
(ii) is indebted to, or has the right under a line of credit to borrow from,
Sandwich or any Sandwich Subsidiary in an amount exceeding $50,000.

     4.23 CERTAIN TRANSACTIONS.  Since December 31, 1996, neither Sandwich nor
any Sandwich Subsidiary has been a party to any material off-balance-sheet
transactions involving interest rate and currency swaps, options and futures
contracts, or any other similar derivative transactions, except as Previously
Disclosed.

     4.24 DISCLOSURES.  None of the representations and warranties of Sandwich 
or any of the written information or documents furnished or to be furnished by
Sandwich to 1855 Bancorp in connection with or pursuant to this Agreement or the

to make any such information or document, in light of the circumstances, not
misleading.

     4.25 STANDSTILL AGREEMENTS.  Sandwich has Previously Disclosed, and has 
provided Compass with true and correct copies of, all standstill agreements (the
"Standstill Agreements") it has entered into pursuant to which any other person
has agreed (i) not to acquire for a period of time any assets or voting
securities of Sandwich, (ii) not to announce or publicly propose any
extraordinary transaction involving Sandwich or its assets or voting securities
or (iii) not to make any solicitation of proxies involving Sandwich's voting 
securities. Except as Previously Disclosed, all of such Previously Disclosed
Standstill Agreements remain in full force and effect as of the date hereof,
such Standstill Agreements have not been amended or waived, Sandwich has not
granted any consents thereunder, and, to Sandwich's knowledge, such Standstill
Agreements are enforceable in accordance with their terms. To Sandwich's
knowledge, no party (other than 1855 Bancorp and Compass Bank) to a Standstill
Agreement with Sandwich owns, directly or indirectly, any shares of Sandwich
Common Stock.

     4.26 DISCLOSURE SCHEDULE.  The Sandwich Disclosure Schedule sets forth, 
among other things, disclosures with respect to or exceptions to Sandwich's
representations and warranties in this Article IV.  The mere inclusion of an
exception in the Sandwich Disclosure Schedule shall not be deemed an admission
by Sandwich that such exception represents a material fact, event or
circumstance.

     4.27 POOLING OF INTERESTS.  Sandwich knows of no reason relating to it why
the Merger would not qualify as a "pooling of interests" for accounting purposes
or a tax free reorganization under Section 368 of the Code. Except as Previously
Disclosed, since January 1, 1996, neither Sandwich nor Sandwich Bank has (A)
issued or permitted to be issued any shares of capital stock, 


                                       21
<PAGE>
 
 
or securities exercisable for or convertible into shares of capital stock, of
Sandwich, Sandwich Bank or any Sandwich Subsidiaries, other than pursuant to and
as required by the terms of any Sandwich Options that were issued and
outstanding on such date; (B) repurchased, redeemed or otherwise acquired,
directly or indirectly through one or more of its Subsidiaries, any shares of
capital stock of Sandwich, Sandwich Bank or any Sandwich Subsidiary, other than
open market purchases in the ordinary course by Sandwich's Employee Stock
Ownership Plan and its Dividend Reinvestment Plan, none of which purchases would
cause the Merger not to qualify as a pooling of interests; or (C) declared, set
aside, made or paid to the stockholders of Sandwich or Sandwich Bank dividends
or other distributions on the outstanding shares of capital stock of Sandwich or
Sandwich Bank. For purposes of clause (B) above, Sandwich and Sandwich Bank
shall be deemed to include any person that Sandwich or Sandwich Bank has caused
to purchase such shares.

conducted and is duly licensed or qualified to do business and is in good
standing in each jurisdiction in which its ownership or leasing of property or
the conduct of its business requires such licensing or qualification, except
where the failure to be so licensed, qualified or in good standing would not
have a Material Adverse Effect on 1855 Bancorp.  1855 Bancorp is duly 
registered as a bank holding company under the BHCA and the regulations of the
FRB thereunder. 1855 Bancorp has heretofore delivered to Sandwich true and
complete copies of the Articles of Organization and Bylaws of 1855 Bancorp as in

     5.3 OWNERSHIP OF THE 1855 BANCORP SUBSIDIARIES.  1855 Bancorp has 
Previously Disclosed each direct or indirect 1855 Bancorp Subsidiary. The
outstanding shares of capital stock of each 1855 Bancorp Subsidiary have been
duly authorized and validly issued, are fully paid and nonassessable and are
directly or indirectly owned by 1855 Bancorp free and clear of all liens,

the 1855 Bancorp Subsidiaries (i) has full power and authority to own or lease
all of its properties and assets and to carry on its business as now conducted,
and (ii) is duly licensed or qualified to do business and is in good standing in
each jurisdiction in which its ownership or leasing of property or the conduct
of its business requires such qualification, except where the failure to be so
licensed, qualified or in good standing would not have a Material Adverse Effect
on 1855 Bancorp. The deposit accounts of Compass Bank are insured by the BIF or,
in the case of certain deposits, the SAIF, to the maximum extent permitted by
the FDIA, and by the Depositors Insurance Fund for amounts in excess of FDIC

obligation of 1855 Bancorp which is enforceable against 1855 Bancorp in
accordance with its terms, subject, as to enforceability, to bankruptcy,
insolvency and other laws of general applicability relating to or affecting
creditors' rights and to general equity principles.

     5.52 Neither the execution and delivery of this Agreement, nor 
consummation of the transactions contemplated hereby (including the Conversion)

     5.14.1 1855 Bancorp has Previously Disclosed all stock option, employee 
stock purchase and stock bonus plans, qualified pension or profit-sharing plans,
any deferred compensation, bonus or group insurance contract or any other
incentive, health and welfare or employee benefit plan or agreement maintained

Bancorp Subsidiary (the "1855 Bancorp Employee Plans"), whether written or oral.
                         ---------------------------                            

     5.14.2 None of 1855 Bancorp, any 1855 Bancorp Subsidiary, any pension plan
maintained by any of them and qualified under Section 401 of the Code or, to the
best of 1855 Bancorp's knowledge, any fiduciary of such plan has incurred any
material liability to the PBGC or the Internal Revenue Service with respect to
any employees of 1855 Bancorp or any 1855 Bancorp Subsidiary.  To the best of

partial withdrawal from a multi-employer plan (as such term is defined in

     5.13.4 A favorable determination letter has been issued by the Internal 
Revenue Service with respect to each 1855 Bancorp Employee Plan which is an
"employee pension benefit plan" (as defined in Section 3(2) of ERISA) (an "1855
Bancorp Pension Plan") which is intended to qualify under Section 401 of the
Code to the effect that such plan is qualified under Section 401 of the Code and

501 of the Code. No such letter has been revoked or, to the best of 1855
Bancorp's knowledge, is threatened to be revoked and 1855 Bancorp does not know
of any ground on which such revocation 

                                       27
<PAGE>
 
 
may be based. Neither 1855 Bancorp nor any 1855 Bancorp Subsidiary has any
liability under any such plan that is not reflected on the consolidated
statement of financial condition of 1855 Bancorp at October 31, 1997 included in
the 1855 Bancorp Financial Statements, other than liabilities incurred in the
ordinary course of business in connection therewith subsequent to the date
thereof.

     5.14.5 To the best of 1855 Bancorp's knowledge, no prohibited transaction 
(which shall mean any transaction prohibited by Section 406 of ERISA and not
exempt under Section 408 of ERISA or Section 4975 of the Code) has occurred with
respect to any 1855 Bancorp Employee Plan which would result in the imposition,

     5.14.6 Full payment has been made (or proper accruals have been 
established) of all contributions which are required for periods prior to the
date hereof, and full payment will be so made (or proper accruals will be so
established) of all contributions which are required for periods after the date
hereof and prior to the Effective Time, under the terms of each 1855 Bancorp
Employee Plan or ERISA; to the best of 1855 Bancorp's knowledge, no accumulated
funding deficiency (as defined in Section 302 of ERISA or Section 412 of the
Code), whether or not waived, exists with respect to any 1855 Bancorp Pension
Plan, and there is no "unfunded current liability" (as defined in Section 412 of
the Code) with respect to any 1855 Bancorp Pension Plan.

     5.14.7 To the best of 1855 Bancorp's knowledge, 1855 Bancorp Employee 
Plans have been operated in compliance in all material respects with the
applicable provisions of ERISA, the Code, all regulations, rulings and
announcements promulgated or issued thereunder and all other applicable
governmental laws and regulations.

     5.14.8 There are no pending or, to the best knowledge of 1855 Bancorp,

Subsidiary is in material default or in non-compliance under any contract,
agreement, commitment, arrangement, lease, insurance policy or other instrument
to which it is a party or by which its assets, business or operations may be
bound or affected, whether entered into in the ordinary course of business or
otherwise and whether written or oral, and there has not occurred any event that
with the lapse of time or the giving of notice, or both, would constitute such a
default or non-compliance.

     5.16 BROKERS AND FINDERS.  Except as Previously Disclosed, neither 1855 
Bancorp nor any 1855 Bancorp Subsidiary, nor any of their respective directors,
officers or employees, has employed any broker or finder or incurred any

transactions contemplated hereby.

     5.17 INSURANCE.  1855 Bancorp and each 1855 Bancorp Subsidiary is insured 
for reasonable amounts with financially sound and reputable insurance companies
against such risks as companies engaged in a similar business would, in
accordance with good business practice, customarily be insured and has
maintained all insurance required by applicable laws and regulations.

     5.18 PROPERTIES.  All real and personal property owned by 1855 Bancorp or

course of its banking business, (iii) such imperfections of title, easements and
encumbrances, if any, as are not material in character, amount or extent and
(iv) as reflected on the consolidated statement of financial condition of 1855
Bancorp as of October 31, 1997 included in the 1855 Bancorp Financial
Statements. All real and personal property which is material to 1855 Bancorp's
business on a consolidated basis and leased or licensed by 1855 Bancorp or an
1855 Bancorp Subsidiary is held pursuant to leases or licenses which are valid
and enforceable in accordance with their respective terms and no such real
property lease will terminate or lapse prior to the Effective Time.

     5.19 LABOR.  No work stoppage involving 1855 Bancorp or any 1855 Bancorp
Subsidiary is pending or, to the best knowledge of 1855 Bancorp, threatened.
Neither 1855 Bancorp nor any 1855 Bancorp Subsidiary is involved in, or
threatened with or affected by, any labor dispute, arbitration, lawsuit or
administrative proceeding involving its employees which could have a Material
Adverse Effect on 1855 Bancorp.  Employees of 1855 Bancorp and the 1855 Bancorp
Subsidiaries are not represented by any labor union nor are any collective
bargaining agreements otherwise in effect with respect to such employees, and to
the best of 1855 Bancorp's knowledge, there have been no efforts to unionize or
organize any employees of 1855 Bancorp or any 1855 Bancorp Subsidiary during the
past five years.

understanding for the purpose of acquiring, holding, voting or disposing of, in
each case, shares of Sandwich Common Stock which in the aggregate represent 5%

   acceleration in accordance with the terms of such Sandwich Options; or

change in the normal course of its business or in the operation of its
properties and, to the extent permitted by applicable law, of any governmental
complaints, investigations or hearings (or communications indicating that the
same may be contemplated), or the institution or the threat of material
litigation involving Sandwich. Sandwich will also provide 1855 Bancorp such
information with respect to such events as 1855 Bancorp may reasonably request
from time to time. As soon as reasonably available, but in no event more than 45
days after the end of each calendar quarter ending after the date of this

meetings, organizational documents, by-laws, material contracts and agreements,
filings with any regulatory authority, litigation files, plans affecting
employees, and any other business activities or prospects in which 1855 Bancorp
may have a reasonable interest; provided, however, that Sandwich shall not be
required to take any action that would provide access to or to disclose
information where such access or disclosure would violate or prejudice the
rights or business interests or confidences of any customer or other person or
would result in the waiver by it of the privilege protecting communications
between it and any of its counsel.  Sandwich shall provide and shall request its
auditors to provide 1855 Bancorp with such historical financial information
regarding it (and related audit reports and consents) as 1855 Bancorp may

Sandwich will promptly supplement or amend the Disclosure Schedules delivered in
connection herewith pursuant to Article IV with respect to any material matter
hereafter arising which, if existing, occurring or known at the date of this
Agreement, would have been required to be set forth or described in such
Disclosure Schedules or which is necessary to correct any information in such
Schedules which has been rendered inaccurate thereby.  No supplement or
amendment to such Schedules shall have any effect for the purpose of determining
satisfaction of the conditions set forth in Article IX.

     6.6 CONSENTS AND APPROVALS OF THIRD PARTIES.  Sandwich shall use all 
reasonable efforts to obtain as soon as practicable all consents and approvals
of any other Persons necessary or desirable for the consummation of the
transactions contemplated by this Agreement. Without limiting the generality of
the foregoing, Sandwich shall utilize the services of a professional proxy
soliciting firm to help obtain the shareholder vote required to be obtained by
it hereunder.

     6.7 ALL REASONABLE EFFORTS.  Subject to the terms and conditions herein
provided, Sandwich agrees to use all reasonable efforts to take, or cause to be
taken, all corporate or other action and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement.
Without limiting the generality of the foregoing, Sandwich agrees to take all
such actions as 1855 Bancorp may reasonably request in order to enforce its
rights under, and hereby grants 1855 Bancorp the irrevocable right and authority
to act as Sandwich's agent for purposes of enforcing its rights under, all
Standstill Agreements to the extent that any other party to any Standstill
Agreement purchases or attempts to purchase any shares of Sandwich Common Stock
in violation thereof.

     6.8 FAILURE TO FULFILL CONDITIONS.  In the event that Sandwich determines 
that a condition to its obligation to complete the Merger cannot be fulfilled
and that it will not waive that condition, it will promptly notify 1855 Bancorp.

     6.9 NO SOLICITATION.  Unless and until this Agreement shall have been 
properly terminated by either party pursuant to Section 111 hereof, neither
Sandwich nor any of its subsidiaries shall (and Sandwich and Sandwich Bank shall

<PAGE>
 
 
representatives, including, but not limited to, investment bankers, attorneys
and accountants, not to), directly or indirectly, encourage, solicit, initiate
or participate in any discussions or negotiations with, or, provide any
information to, any corporation, partnership, person or other entity or group
(other than 1855 Bancorp and its affiliates or Representatives) concerning any
merger, tender offer, sale of substantial assets, sale of shares of capital
stock or debt securities or similar transaction involving Sandwich or Sandwich
Bank (an "Acquisition Transaction"); provided, however that Sandwich and its
          -----------------------                                           
representatives shall be permitted to participate in discussions or negotiations
with, or provide information to, any other corporation, partnership, person or
other entity or group with respect to an Acquisition Transaction if the Board of
Directors of Sandwich determines (in good faith upon the advice of outside
counsel) that their fiduciary duties require them to do so.  Notwithstanding the
foregoing, nothing contained in this Section 6.9 shall prohibit Sandwich or its
Board of Directors from taking and disclosing to Sandwich's stockholders a
position with respect to a tender offer by a third party pursuant to Rules 14d-9
and 14e-2(a) promulgated under the Exchange Act or from making such disclosure
to Sandwich's stockholders which, in the judgment of the Board of Directors
(upon the advice of counsel), may be required under applicable law or is
necessary in order to comply with its fiduciary obligations.  Sandwich will
immediately communicate to 1855 Bancorp the terms of any proposal, discussion,
negotiation or inquiry relating to an Acquisition Transaction and the identity
of the party making such proposal or inquiry which it may receive in respect of
any such transaction (which shall mean that any such communication shall be
delivered no less promptly than by telephone within 24 hours of Sandwich's
receipt of any such proposal or inquiry) or its receipt of any request for
information from the FRB, the DOJ, or any other governmental agency or authority
with respect to a proposed Acquisition Transaction.  Sandwich shall continue to
consult with 1855 Bancorp after receipt of such proposal or commencement of such
discussion or negotiation relating to an Acquisition Transaction, and will not
take any action with respect to such proposed Acquisition Transaction except
after reasonable consultation with 1855 Bancorp.

     6.10 CEASE NEGOTIATIONS.  Sandwich hereby agrees to cease all pending 
discussions or negotiations with other interested persons relating to a possible
merger with or acquisition of Sandwich, and to instruct all such persons to
immediately return to Sandwich all copies of the evaluation materials provided
to such persons by Sandwich, without retaining any copy thereof, and to destroy
any notes such persons or their representatives may have prepared relating to a
possible combination with Sandwich, as required by the terms of the Standstill
Agreements between such parties and Sandwich; provided, however, that the
foregoing shall not be deemed to prevent Sandwich from acting in the future in
the manner permitted by Section 6.9.

tions contemplated hereby or materially increase the period of time necessary to

     7.9.1 All employees of Sandwich and its Subsidiaries as of the Effective 
Time shall become employees of 1855 Bancorp or an 1855 Bancorp Subsidiary as of
the Effective Time. Nothing in this Agreement shall give any employee of
Sandwich or its Subsidiaries a right to continuing employment with 1855 Bancorp
or any Subsidiary thereof after the Effective Time. Any employee of Sandwich or
any Sandwich Subsidiary whose employment with 1855 Bancorp or any 1855 Bancorp
Subsidiary is terminated by 1855 Bancorp within one year after the Effective
Time shall be entitled to receive (i) a lump-sum severance benefit in an amount
equal to two-weeks' pay for each year of employment (with partial years of
service included in the calculation on a pro-rated basis), up to a maximum of 26
weeks' pay, and (ii) continuation of health benefits, on the same terms and
conditions applicable to 1855 Bancorp's active employees, for the same number of
weeks factored into the calculation of severance payments, and thereafter COBRA
benefits for an additional period of time determined as though the Sandwich
employee terminates employment upon expiration of the period covered by said
continued health benefits.

     7.9.2 As soon as practicable after the Effective Time, 1855 Bancorp shall
provide or cause to be provided to all employees of Sandwich and any Sandwich

after the Effective Time with 

                                       37
<PAGE>
 
 
employee benefits which, in the aggregate, are no less favorable than those
generally afforded to other em ployees of 1855 Bancorp or the 1855 Bancorp
Subsidiaries holding similar positions, subject to the terms and conditions
under which those employee benefits are made available to such employees,
provided, however, that (i) for purposes of determining eligibility for and
vesting of such employee benefits only (and not for pension benefit accrual
purposes), service with Sandwich or any Sandwich Subsidiary prior to the
Effective Time shall be treated as service with an "employer" as if such persons
had been employees of 1855 Bancorp, to the extent permissible under the terms of
1855 Bancorp's Employee Plans, (ii) this Section 7.9 shall not be construed to
limit the ability of 1855 Bancorp and its Subsidiaries to terminate the 
employment of any employee or to review employee benefits programs from time to
time and to make such changes as they deem appropriate, and (iii) 1855 Bancorp
or a Subsidiary shall continue to provide post-retirement medical benefits to
former employees of Sandwich who as of the Effective Time are receiving post-
retirement medical benefits in accordance with Sandwich's Previously Disclosed
retiree health care Plans I, II, and III, (iv) 1855 Bancorp shall honor any and
all vacation leave (but not sick leave) accrued by Sandwich's employees, except
to the extent of any duplication of benefits, and (v) no preexisting condition
exclusion that is currently inapplicable to a Sandwich employee and/or the
employee's covered dependents shall affect their rights to health benefits or
coverage under 1855 Bancorp's plans, to the extent permissible under such plans.

     7.9.3 Sandwich has Previously Disclosed to 1855 Bancorp certain employment
and change of control agreements, deferred compensation plans, Grantor Trust
Agreement, Supplemental Retirement Plans and Split Dollar Insurance Agreements
(collectively, "Benefit Agreements") and the Sandwich Employee Stock Ownership
Plan (the "ESOP"). Following the Effective Time, 1855 Bancorp shall honor or
cause its Subsidiaries to honor in accordance with their terms all such
Previously Disclosed Benefit Agreements and the ESOP and assume or cause its
Subsidiaries to assume all duties, liabilities and obligations under such
agreements and arrangements. 1855 Bancorp agrees that (i) the consummation of
the transactions contemplated hereby constitutes a "Change in Control" as
defined in the Benefit Agreements, and (ii) each of Sandwich's officers who is
party to an employment agreement with Sandwich will be deemed to have suffered a
material change in their responsibilities and supervision as of the Effective
Time, it being understood that the President of Sandwich shall terminate
employment as of the Effective Time and receive payments under Section 11(a) of
his Employment at such time.

     7.10 DIRECTORS AND OFFICERS INDEMNIFICATION AND INSURANCE.

     7.10.1 1855 Bancorp shall maintain, or shall cause Compass Bank to 
maintain, in effect for six years from the Effective Time, if available, the
current directors' and officers' liability insurance policies maintained by
Sandwich (provided, that 1855 Bancorp may substitute therefor policies of at
least the same coverage containing terms and conditions which are not materially
less favorable) with respect to matters occurring prior to the Effective Time;
provided, however, that in no event shall 1855 Bancorp be required to expend
pursuant to this Section 7.10.1 more than $60,000 in the aggregate. In 
connection with the foregoing, Sandwich agrees to provide such insurer or 
substitute insurer with such representations as such insurer may request with 
respect to the reporting of any prior claims.

     7.10.2 From and after the Effective Time, 1855 Bancorp shall, or shall 
cause Compass Bank to, indemnify, defend and hold harmless each person who is
now, or who has been at any time before the date hereof or who becomes before
the Effective Time, an officer or director 

                                       38
<PAGE>
 
 
of Sandwich or the Sandwich Subsidiaries or any of their respective subsidiaries
(the "Indemnified Parties") against all losses, claims, damages, costs, expenses
(including attorney's fees), liabilities or judgments or amounts that are paid
in settlement (which settlement shall require the prior written consent of 1855
Bancorp, which consent shall not be unreasonably withheld) of or in connection
with any claim, action, suit, proceeding or investigation, whether civil,
criminal, or administrative (each a "Claim"), in which an Indemnified Party is,
or is threatened to be made, a party or witness in whole or in part on or
arising in whole or in part out of the fact that such person is or was a
director, officer or employee of Sandwich or any of its subsidiaries if such
Claim pertains to any matter of fact arising, existing or occurring before the
Effective Time (including, without limitation, the Merger and the other 
transactions contemplated hereby), regardless of whether such Claim is asserted
or claimed before, or at or after, the Effective Time (the "Indemnified
Liabilities"), to the fullest extent permitted under applicable state or federal
law in effect as of the date hereof or as amended applicable to a time before
the Effective Time and under Sandwich's and Sandwich Bank's Articles of
Organization or Charter and By-Laws. 1855 Bancorp shall pay expenses in advance
of the final disposition of any such action or proceeding to each Indemnified
Party to the full extent permitted by applicable state or federal law in effect
as of the date hereof or as amended applicable to a time before the Effective
Time upon receipt of an undertaking to repay such advance payments if he shall
be adjudicated or determined to be not entitled to indemnification in the manner
set forth below. Any Indemnified Party wishing to claim indemnification under
this Section 7.10.2 upon learning of any Claim, shall notify 1855 Bancorp (but
the failure so to notify 1855 Bancorp shall not relieve it from any liability
which it may have under this Section 7.10.2, except to the extent such failure
materially prejudices 1855 Bancorp) and shall deliver to 1855 Bancorp the
undertaking referred to in the previous sentence. In the event of any such Claim
(whether arising before or after the Effective Time) (1) 1855 Bancorp shall have
the right to assume the defense thereof (in which event the Indemnified Parties
will cooperate in the defense of any such matter) and upon such assumption 1855
Bancorp shall not be liable to any Indemnified Party for any legal expenses of
other counsel or any other expenses subsequently incurred by any Indemnified
Party in connection with the defense thereof, except that if 1855 Bancorp elects
not to assume such defense, or counsel for the Indemnified Parties reasonably
advises the Indemnified Parties that there are or may be (whether or not any
have yet actually arisen) issues which raise conflicts of interest between 1855
Bancorp and the Indemnified Parties, the Indemnified Parties may retain counsel
reasonably satisfactory to them, and 1855 Bancorp shall pay the reasonable fees
and expenses of such counsel for the Indemnified Parties, (2) 1855 Bancorp shall
be obligated pursuant to this paragraph to pay for only one firm of counsel for
all Indemnified Parties whose reasonable fees and expenses shall be paid
promptly as statements are received, (3) 1855 Bancorp shall not be liable for
any settlement effected without its prior written consent (which consent shall
not be unreasonably withheld) and (4) no Indemnified Party shall be entitled to
indemnification hereunder with respect to a matter as to which (x) he shall have
been adjudicated in any proceeding not to have acted in good faith in the
reasonable belief that his action was in the best interests of Sandwich or any
Subsidiary, or (y) in the event that a proceeding is compromised or settled so
as to impose any liability or obligation upon an Indemnified Party, if there is
a determination that with respect to said matter said Indemnified Party did not
act in good faith in the reasonable belief that his action was in the best
interests of Sandwich or any Subsidiary. The determination shall be made by a
majority vote of the Directors of 1855 Bancorp who were formerly directors of
Sandwich and who are not involved in such proceeding (the "Former Sandwich
Directors"), or, if a majority of the Former Sandwich Directors are involved in
the proceeding, by a committee of three 

                                       39

disinterested Former Sandwich Directors chosen by all of the Former Sandwich
Directors for the purpose of making such determination.

successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving bank or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any person, then, and in each such case, proper provision shall be made so
that the successors and assigns of 1855 Bancorp shall assume the obligations set
forth in this Section 7.10.

     7.10.4 The obligations of 1855 Bancorp provided under this Section 7.10 are
intended to be enforceable against 1855 Bancorp directly by the Indemnified
Parties and shall be binding on all respective successors and permitted assigns
of 1855 Bancorp.

     7.11 MERGER SUB.  Prior to the Effective Time, 1855 Bancorp will take any 
and all necessary action to cause (i) Merger Sub to be organized, (ii) Merger
Sub to become a direct or indirect wholly-owned subsidiary of 1855 Bancorp,
(iii) the directors and stockholder or stock holders of Merger Sub to approve
the transactions contemplated by this Agreement, and (iv) Merger Sub to execute
one or more counterparts of this Agreement and to deliver at least one such
counterpart so executed to Sandwich, whereupon Merger Sub shall become a party
to and be bound by this Agreement.

     7.12 STOCK LISTING.  1855 Bancorp agrees to list on the Stock Exchange 
(or such other national securities exchange on which the shares of 1855 Bancorp
Common Stock shall be listed as of the date of consummation of the Merger),
subject to official notice of issuance, the shares of 1855 Common Stock to be

terminate this Agreement or shall fail to take any action necessary to effect
the consummation of the Merger (including, without limitation, 1855 Bancorp's
obligation to satisfy the condition set forth in Section 9.3.6), the other party

     11.2.1 In the event of termination of this Agreement pursuant to any

12.1, 12.2, 12.6, 12.9, 12.10, this Section 11.2, and any other Section which,

     11.2.2 If this Agreement is terminated, expenses and damages of the parties
hereto shall be determined as follows:

       (a)  Subject to Sections 11.3 and 11.4, termination of this Agreement
   pursuant to Section 11.1 (other than termination pursuant to Sections 11.1.2
   and 11.1.3 as a result of a willful breach or gross negligence by a party 
   hereto) shall be without liability, cost or expense on the part of any 
   party to the other.

       (b)  In the event of a termination of this Agreement pursuant to Section
   11.1.2 or 11.1.3 hereof resulting from the willful conduct or gross 
   negligence of a party, such party shall be obligated to reimburse the other 
   party for up to $1,000,000 of 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 "Costs").  The payment of Costs 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 or as is contemplated
   herein.  Notwithstanding anything to the contrary herein, if (i) Sandwich
   makes the payment contemplated in Section 11.4 of this Agreement or (ii) if
   1855 Bancorp makes the payment contemplated in Section 11.3 of this 
   Agreement, such party shall not have any further liability to the other 
   party (or its Subsidiaries), whether for Costs, breach or otherwise.

     11.2.3 Except as provided in Sections 11.2.2, 11.3 and 11.4, whether or 
not the Merger is consummated, all Costs incurred in connection with this 
Agreement and the transactions contemplated hereby shall be borne by the party
incurring such costs and expenses.

     11.2.4 In no event shall any officer, agent or director of Sandwich, any
Sandwich Subsidiary, 1855 Bancorp or any 1855 Bancorp Subsidiary, be personally
liable thereunder for any default by any party in any of its obligations
hereunder unless any such default was intentionally caused by such officer,
agent or director.

     11.3 1855 BANCORP SPECIAL PAYMENT.  As a condition of Sandwich's 
willingness to, and in order to induce Sandwich to, enter into this Agreement,
and to reimburse Sandwich for incurring the damages, costs and expenses related
to entering into this Agreement and consummating the transactions contemplated
by this Agreement, 1855 Bancorp hereby agrees to pay to Sandwich, as liquidated
damages and in lieu of any other rights or remedies under this Agreement, a
payment in the amount of $6,000,000 (the "Special Payment") if and only if (i)
                                          ---------------
the Merger is not consummated and the Agreement is terminated in accordance 
with its terms due to the failure of the condition set forth in Section 9.1.7 of
this Agreement, or (ii) the Agreement is terminated pursuant to Section 11.1.7
or (iii) 1855 Bancorp otherwise does not consummate the Conversion by no later
than February 20, 1999 (subject to the one month extension contemplated in 
Section 11.1.4 herein), or (iv) Sandwich has terminated this Agreement in 
accordance with Section 11.1.2 or 11.1.3 because 1855 Bancorp has intentionally
or willfully breached any of its representations or warranties herein or 
intentionally and willfully failed to perform or comply with any of its 
covenants or agreements herein, to such extent as to permit such termination 
(such reasons for termination being hereinafter referred to as the 
"Special Payment Event"). It is understood and agreed that 1855 Bancorp does 
 ---------------------
not intend to (and shall not be obligated to) consummate the Conversion unless 
the conditions to its obligations to consummate the Merger have been satisfied 
on or before the Pre-Closing Date. Notwithstanding the foregoing, 1855 Bancorp 
shall have no obligation to make any Special Payment to Sandwich if the Special
Payment Event is primarily due to a breach of a representation or warranty of 
Sandwich (subject to the standard set forth in Section 9.2.1 of this Agreement)
or a breach by Sandwich of one or more covenants in this Agreement (subject to
the standard set forth in Section 9.2.2 of this Agreement), which breach of 
representation, warranty or covenant directly or adversely affects 1855 
Bancorp's ability to consummate the Merger or satisfy the condition set forth 
in Section of this 9.1.7 Agreement.

     11.3.1 PAYMENTS REQUIRED.  Any payment required to be made under this 
Section 11.3 shall be paid by 1855 Bancorp to Sandwich by wire transfer of
immediately available funds to an account designated by Sandwich within five
business days after demand by Sandwich.

     11.3.2 EXCLUSIVITY OF REMEDY.  Notwithstanding anything to the contrary set
forth in this Agreement, if 1855 Bancorp pays or causes to be paid to Sandwich
the Special Payment, neither 1855 Bancorp nor Compass Bank will have any further
obligations or liabilities to Sandwich or Sandwich Bank with respect to this
Agreement or the transactions contemplated by this Agreement.

     11.4 SANDWICH CHANGE IN CONTROL EXPENSE FEE. As a condition of 1855 
Bancorp's willingness to, and in order to induce 1855 Bancorp to, enter into 
this Agreement, and to reimburse 1855 Bancorp for incurring the damages, costs
and expenses related to entering into this Agreement and consummating the
transactions contemplated by this Agreement, Sandwich hereby agrees to pay to
1855 Bancorp, as liquidated damages, and in lieu of any other rights or remedies

   merger, consolidation, share exchange or any similar transaction) securities
   representing 15% or more of the voting power of Sandwich or any Sandwich
   Subsidiary (any of the foregoing a "Change of Control Transaction"); or

       (b)  any person (other than 1855 Bancorp or any 1855 Bancorp Subsidiary)

   beneficial ownership of, or any "group" (as such term is defined in Section

   any person (other than 1855 Bancorp or any subsidiary of 1855 Bancorp) shall
   have been made to Sandwich or its stockholders to engage in a Change of
   Control Transaction, (y) any person (other than 1855 Bancorp or any
   subsidiary of 1855 Bancorp) shall have stated its intention to Sandwich or

            (iii)  Sandwich shall have willfully or intentionally breached
     any representation, warranty, covenant or obligation contained in this
     Agreement and such breach would entitle 1855 Bancorp to terminate this
     Agreement under Section 11.1.2 or 11.1.3 hereof (without regard to the 
     cure period provided for therein unless such cure is promptly effected 
     without jeopardizing consummation of the Merger pursuant to the terms of 
     this Agreement); or

     (iv) The Merger shall not have been consummated by reason of failure
     of the pooling of interests condition, and such failure is the result
     of the actions of a party not affiliated with either 1855 Bancorp or
     Sandwich.

     11.4.3  DURATION OF 1855 BANCORP'S RIGHTS WITH RESPECT TO EXPENSE FEE.
Notwithstanding any other provision of this Agreement, the provisions of this
Section 11.4 shall remain in effect and shall be enforceable by 1855 Bancorp or

under circumstances that would trigger a payment under this Section 11.4, the
standstill provisions contained in the Confidentiality Agreement shall
terminate.

     11.4.5 EXCLUSIVITY OF REMEDY. Notwithstanding anything to the contrary set
forth in this Agreement, if Sandwich pays or causes to be paid to 1855 Bancorp

stockholders, any amendment of this Agreement which reduces the amount or
changes the form of consideration to be delivered to Sandwich's stockholders
pursuant to this Agreement. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto. 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 re spect to, any subsequent or other failure.

                                  WITNESSETH:

          WHEREAS, Issuer, Grantee, Compass Bank and Sandwich Bank have entered

                                                               ------       

          WHEREAS, as a condition and inducement to Grantee's execution of the

the Affiliation Agreement, and intending to be legally bound hereby, Issuer and
Grantee agree as follows:

purchase up to 387,107 shares (as adjusted as set forth herein, the "Option
                                                                     ------

such Option Shares) of Common Stock, par value $1.00 per share ("Issuer Common
                                                                 -------------

of $57.00, provided, however, that in no event shall the number of Option Shares
for which the Option is exercisable exceed 19.9% of the issued and outstanding
shares of Issuer Common Stock without giving effect to any shares subject to or
issued pursuant to the Option. The number of shares of Issuer Common Stock that
may be received upon the exercise of the Option and the Purchase Price are
subject to adjustment as herein set forth.

               3.  EXERCISE OF OPTION.

          (a)  Grantee or Holder (as hereinafter defined) may exercise the
Option, in whole or in part, at any time and from time to time following the
occurrence of a Purchase Event (as hereinafter defined) and before an Exercise
Termination Event (as hereinafter defined).  Each of the following shall be an
"Exercise Termination Event":

   (i)  The Effective Time (as defined in the Affiliation Agreement) of the
   Merger,
   (ii)  The passage of 12 months after termination of the Affiliation Agreement
   following the occurrence of a Purchase Event or a Preliminary Purchase Event;
<PAGE>
 
   (iii)  The date on which the Affiliation Agreement is terminated in
   accordance with its terms, but only if such termination takes place prior to
   the occurrence of a Purchase Event or a Preliminary Purchase Event; and

   (iv)  The passage of 12 months after the Affiliation Agreement is terminated
   by Grantee pursuant to Section 11.1.2 or 11.1.3 of the Affiliation Agreement.

Any purchase of shares upon exercise of the Option shall be subject to
compliance with applicable laws, including without limitation the Bank Holding
Company Act of 1956, as amended (the "BHC Act"), and the Bank Merger Act, as
                                      -------                               
amended ("Bank Merger Act").  The term "Holder" shall mean the holder or holders
          ---------------               ------                                  
of the Option from time to time (subject to the limitations contained in Section
12(h)). The Grantee is the initial Holder.  The rights set forth in Section 8
hereof shall terminate when the right to exercise the Option terminates (other
than as a result of a complete exercise of the Option) as set forth above.

   (b)  As used herein, a "Purchase Event" means any of the following events:
                           --------------                  

             (i)  Without Grantee's prior written consent, Issuer shall have
   authorized, recommended or publicly proposed, or publicly announced an
   intention to authorize, recommend or propose, or entered into an agreement
   with any person (other than Grantee or any subsidiary of Grantee) to effect
   (A) a merger, consolidation or similar transaction involving Issuer or any of
   its subsidiaries, (B) the disposition, by sale, lease, exchange or otherwise,
   of assets of Issuer or any Issuer Subsidiary representing in either case 15%
   or more of the consolidated assets of Issuer and the Issuer Subsidiaries, or
   (C) the issuance, sale or other disposition of (including by way of merger,
   consolidation, share exchange or any similar transaction) securities
   representing 15% or more of the voting power of Issuer or any of the Issuer
   Subsidiaries (any of the foregoing an "Acquisition Transaction"); or
                                          -----------------------      

             (ii)  any person (other than Grantee or any subsidiary of Grantee)
   shall have acquired beneficial ownership (as such term is defined in Rule
   13d-3 promulgated under the Exchange Act) of or the right to acquire
   beneficial ownership of, or any "group" (as such term is defined in Section
                                    -----                                     
   13(d)(3) of the Exchange Act) shall have been formed which beneficially owns
   or has the right to acquire beneficial ownership of, 25% or more of the then
   outstanding shares of Issuer Common Stock.

               (c)  As used herein, a "Preliminary Purchase Event" means any of
                                       --------------------------              
the following events:

             (i)  any person (other than Grantee or any subsidiary of Grantee)
   shall have commenced (as such term is defined in Rule 14d-2 under the
   Exchange Act), or shall have filed a registration statement under the
   Securities Act with respect to, a tender offer or exchange offer to purchase
   any shares of Issuer Common Stock such that, upon consummation of such offer,
   such person would own or control 10% or more of the then outstanding shares
   of Issuer Common Stock (such an offer being referred to herein as a "Tender
                                                                        ------
   Offer" and an "Exchange Offer," respectively); or
   -----          --------------                    

             (ii) following the public announcement of an Acquisition Proposal
   (which the parties hereto acknowledge has already taken place), the holders
   of Issuer Common Stock shall not have approved the Affiliation Agreement at
   the meeting of such stockholders held for the purpose of voting on the
   Affiliation Agreement (the term ""Acquisition Proposal" is defined to mean
                                     --------------------                    
   (x) a bona fide proposal by any person (other than Grantee or any subsidiary
   of Grantee) shall have been made to Issuer or its stockholders to engage in a
   Acquisition Transaction, (y) any person (other than Grantee or any subsidiary

                                      -2-
<PAGE>
 
   of Grantee) shall have stated its intention to Issuer or its stockholders to
   make a proposal to engage in a Acquisition Transaction if the Affiliation
   Agreement terminates or (z) any person (other than Grantee or any subsidiary
   of Grantee) shall have filed an application or notice with any Governmental 
   Entity to engage in a Acquisition Transaction); or

             (iii)  following the occurrence of an Acquisition Proposal (which
   the parties hereto acknowledge has already taken place):

             (A) the meeting of Issuer stockholders held for the purpose of
   voting on the Affiliation Agreement shall not have been held or shall have
   been canceled prior to termination of the Affiliation Agreement,

             (B) Issuer's Board of Directors shall have withdrawn or modified,
   or publicly announced its intention to withdraw or modify, in a manner
   adverse to Grantee the recommendation of Issuer's Board of Directors with
   respect to the Affiliation Agreement and the Merger;

             (C)  Issuer shall have breached any representation, warranty,
   covenant or obligation contained in the Affiliation Agreement and such breach
   would entitle Grantee to terminate the Affiliation Agreement under Section
   11.1.2 or 11.1.3 of the Affiliation Agreement (without regard to the cure
   period provided for therein unless such cure is promptly effected without
   jeopardizing consummation of the Merger pursuant to the terms of the
   Affiliation Agreement); or

             (D)  The Merger shall not have been consummated by reason of
      failure of the pooling of interests condition, and such failure is the
      result of the actions of a party not affiliated with either Grantee or
      Issuer; or

             (iv) any person other than Grantee or any Grantee Subsidiary, other
   than in connection with a transaction to which Grantee has given its prior
   written consent, shall have (x) acquired beneficial ownership or the right to
   acquire beneficial ownership of 10% or more of the outstanding shares of
   Issuer Common Stock or (y) filed an application or notice with the Federal
   Reserve Board, or other federal or state bank regulatory authority, which
   application or notice has been accepted for processing, for approval to
   acquire beneficial ownership of 10% or more of the outstanding shares of
   Issuer Common Stock or otherwise to engage in an Acquisition Transaction.

          As used in this Agreement, "person" shall have the meaning specified
                                      ------                                  
in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.

          (d)  Issuer shall notify Grantee promptly in writing of the occurrence
of any Preliminary Purchase Event or Purchase Event, it being understood that
the giving of such notice by Issuer shall not be a condition to the right of
Holder to exercise the Option.

          (e)  In the event Holder wishes to exercise the Option, it shall send
to Issuer a written notice (the date of which being herein referred to as the

purchase pursuant to such exercise, and (ii) a place and date not earlier than
three business days nor later than 15 business days from the Notice Date for the
closing (the "Closing") of such purchase (the "Closing Date").  If prior
              -------                          ------------

System (the "Federal Reserve Board"), the 
             ---------------------

<PAGE>
 
Federal Deposit Insurance Corporation, the Massachusetts Division of Banks, or 
any other Governmental Entity is required in connection with such purchase,
Issuer shall cooperate with Grantee in the filing of the required notice of
application for approval and the obtaining of such approval and the Closing
shall occur immediately following such regulatory approvals (and any mandatory
waiting periods). Any exercise of the Option shall be deemed to occur on the
Notice Date relating thereto.

          4.  PAYMENT AND DELIVERY OF CERTIFICATES.

          (a)  On each Closing Date, Holder shall (i) pay to Issuer, in 
immediately available funds by wire transfer to a bank account designated by
Issuer, an amount equal to the Purchase Price multiplied by the number of Option
Shares to be purchased on such Closing Date, and (ii) present and surrender this
Agreement to Issuer at the address of Issuer specified in Section 12(f) hereof.

          (b)  At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 4(a), (i)
Issuer shall deliver to Holder (A) a certificate or certificates representing
the Option Shares to be purchased at such Closing, which Option Shares shall be
free and clear of all liens, claims, charges and encumbrances of any kind
whatsoever and subject to no preemptive rights, and (B) if the Option is
exercised in part only, an executed new agreement with the same terms as this
Agreement evidencing the right to purchase the balance of the shares of Issuer
Common Stock purchasable hereunder, and (ii) Holder shall deliver to Issuer a
letter agreeing that Holder shall not offer to sell or otherwise dispose of such
Option Shares in violation of applicable federal and state law or of the
provisions of this Agreement.

          (c)  In addition to any other legend that is required by applicable
law, certificates for the Option Shares delivered at each Closing shall be
endorsed with a restrictive legend which shall read substantially as follows:

               THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS
      SUBJECT TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS
      AMENDED, AND PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF
      MARCH 23, 1998.  A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE HOLDER
      HEREOF WITHOUT CHARGE UPON RECEIPT BY ISSUER OF A WRITTEN REQUEST
      THEREFOR.

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if Holder shall have delivered to Issuer a copy of a letter from the staff of
the SEC, or an opinion of counsel, in form and substance reasonably satisfactory
to Issuer, to the effect that such legend is not required for purposes of the
1933 Act; (ii) the reference to the provisions to this Agreement in the above
legend shall be removed by delivery of substitute certificate(s) without such
reference if the shares have been sold or transferred in compliance with the
provisions of this Agreement and under circumstances that do not require the
retention of such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

          (d)  Upon the giving by Holder to Issuer of the written notice of
exercise of the Option provided for under Section 3(e), the tender of the
applicable purchase price in immediately available funds and the tender of this
Agreement to Issuer, Holder shall be deemed to be the holder 

                                      -4-
<PAGE>
 
of record of the shares of Issuer Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of Issuer shall then be closed or
that certificates representing such shares of Issuer Common Stock shall not then
be actually delivered to Holder.

          (e)  Issuer agrees (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Issuer Common Stock so that the Option may be exercised without additional
authorization of Issuer Common Stock so that the Option may be exercised without
requiring Issuer's stockholders to approve an increase in the number of
authorized shares of Issuer Common Stock after giving effect to all other
options, warrants, convertible securities and other rights to purchase Issuer
Common Stock, (ii) that it will not, by charter amendment or through
reorganization, consolidation, merger, dissolution or sale of assets, or by any
other voluntary act, avoid or seek to avoid the observance or performance of any
of the covenants, stipulations or conditions to be observed or performed
hereunder by Issuer, (iii) promptly to take all action as may from time to time
be required (including (A) complying with all premerger notification, reporting
and waiting period requirements and (B) in the event prior approval of or notice
to any Governmental Entity is necessary before the Option may be exercised,
cooperating fully with Holder in preparing such applications or notices and
providing such information to such Governmental Entity as it may require) in
order to permit Holder to exercise the Option and Issuer duly and effectively to
issue shares of Issuer Common Stock pursuant hereto, and (iv) promptly to take
all action provided herein to protect the rights of Holder against dilution.

          5.  REPRESENTATIONS AND WARRANTIES OF ISSUER.  Issuer hereby
represents and warrants to Grantee (and Holder, if different than Grantee) as
follows:

          (a) CORPORATE POWER AND AUTHORITY.  Issuer has all requisite corporate
power and authority to enter into this Agreement, and subject to any approvals
referred to herein, to consummate the transactions contemplated hereby.  The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Issuer, and this Agreement has been duly
executed and delivered by Issuer.

          (b)  NO VIOLATIONS.  The execution and delivery of this Agreement, the
consummation of the transactions contemplated hereby and compliance by Issuer
with any of the provisions hereof will not (i) conflict with or result in a
breach of any provision of its Articles of Organization or Bylaws or a default
(or give rise to any right of termination, cancellation or acceleration) under
any of the terms, conditions or provisions of any note, bond, debenture,
mortgage, indenture, license, material agreement or other material instrument or
obligation to which Issuer is a party, or by which it or any of its properties
or assets may be bound, or (ii) violate any order, writ, injunction, decree,
statute, rule or regulation applicable to Issuer or any of its properties or
assets.

          (c)  AUTHORIZED STOCK.  Issuer has taken all necessary corporate and
other action to authorize and reserve and to permit it to issue, and at all
times from the date hereof until the obligation to deliver Issuer Common Stock
upon the exercise of the Option terminates, will have reserved for issuance upon
exercise of the Option that number of shares of Issuer Common Stock equal to the
maximum number of shares of Issuer Common Stock at any time and from time to
time purchasable upon exercise of the Option, and all such shares, upon issuance
pursuant to the Option, will be duly and validly issued, fully paid and
nonassessable, and will be delivered free and clear of all liens, claims,
charges and encumbrances of any kind or nature whatsoever and not subject to any
preemptive rights.

          (a) CORPORATE POWER AND AUTHORITY.  Grantee has all requisite
corporate power and authority to enter into this Agreement and, subject to any
approvals or consents referred to herein, to consummate the transactions
contemplated hereby.  The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary corporate action on the part of Grantee, and this Agreement 
has been duly executed and delivered by Grantee.

          (b) The Option is not being, and any shares of Issuer Common Stock or
other securities acquired by Grantee upon exercise of the Option will not be,
acquired with a view to the public distribution thereof and will not be
transferred or otherwise disposed of except in a transaction registered or
exempt from registration under the 1933 Act.

          7.  ADJUSTMENT UPON CHANGES IN ISSUER CAPITALIZATION, ETC.

          (a)  In the event of any change in Issuer Common Stock by reason of a
stock dividend, stock split, split-up, recapitalization, combination, exchange
of shares or similar transaction, the type and number of shares or securities
subject to the Option, and the Purchase Price therefor, shall be adjusted
appropriately, and proper provision shall be made in the agreements governing
such transactions so that Holder shall receive, upon exercise of the Option, the
number and class of shares or other securities or property that Holder would
have received in respect of Issuer Common Stock if the Option had been exercised
immediately prior to such event, or the record date therefor, as applicable.  If
any additional shares of Issuer Common Stock are issued after the date of this
Agreement (other than pursuant to an event described in the first sentence of
this Section 7(a)), the number of shares of Issuer Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of Issuer Common Stock previously issued pursuant hereto, equals 19.9% of
the number of shares of Issuer Common Stock then issued and outstanding, without
giving effect to any shares subject to or issued pursuant to the Option.

          (b)  In the event that Issuer shall enter into an agreement:  (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Issuer Common Stock shall be changed into or exchanged for stock or
other securities of Issuer or any other person or cash or any other property or
the outstanding shares of Issuer Common Stock immediately prior to such merger
shall after such merger represent less than 50% of the outstanding shares and
share equivalents of the merged company, or (iii) to sell or otherwise transfer
all or substantially all of its assets to any person, other than Grantee or one
of its subsidiaries, then, and in each such case, the agreement governing such
transaction shall make proper provisions so that the Option shall, upon the
consummation of any such transaction and upon the terms and conditions set forth
herein, be converted into, or exchanged for, an option (the "Substitute
                                                             ----------
Option"), at the election of Holder, of any of (x) the Acquiring Corporation (as
hereinafter defined), (y) any person that controls the Acquiring Corporation or
(z) in the case of a merger described in clause (ii), Issuer (such person being
referred to as "Substitute Option Issuer").
                ------------------------   

                                      -6-
<PAGE>
 
          (c)  The Substitute Option shall have the same terms as the Option,
provided that, if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to Holder.  Substitute Option Issuer also shall enter
into an agreement with Holder in substantially the same form as this Agreement,
which shall be applicable to the Substitute Option.

          (d)  The Substitute Option shall be exercisable for such number of
shares of Substitute Common Stock (as hereinafter defined) as is equal to the
Assigned Value (as hereinafter defined) multiplied by the number of shares of
Issuer Common Stock for which the Option was theretofore exercisable, divided by
the Average Price (as hereinafter defined).  The exercise price of Substitute
Option per share of Substitute Common Stock (the "Substitute Option Price")
                                                  -----------------------  
shall then be equal to the Purchase Price multiplied by a fraction in which the
numerator is the number of shares of Issuer Common Stock for which the Option
was theretofore exercisable and the denominator is the number of shares of the
Substitute Common Stock for which the Substitute Option is exercisable.

             (e)  The following terms have the meanings indicated:

             (1)  "Acquiring Corporation" shall mean (i) the continuing or
                   ---------------------                                  
   surviving corporation of a consolidation or merger with Issuer (if other than
   Issuer), (ii) Issuer in a merger in which Issuer is the continuing or
   surviving person, or (iii) the transferee of all or substantially all of
   Issuer's assets (or a substantial part of the assets of its subsidiaries
   taken as a whole).

             (2)  "Substitute Common Stock" shall mean the shares of capital
                   -----------------------                                  
   stock (or similar equity interest) with the greatest voting power in respect
   of the election of directors (or persons similarly responsible for the
   direction of the business and affairs) of the Substitute Option Issuer.

             (3)  "Assigned Value" shall mean the highest of (w) the price per
                   --------------                                             
   share of Issuer Common Stock at which a Tender Offer or an Exchange Offer
   therefor has been made (other than by Holder), (x) the price per share of
   Issuer Common Stock to be paid by any third party pursuant to an agreement
   with Issuer, (y) the highest closing price for shares of Issuer Common Stock
   within the six-month period immediately preceding the consolidation, merger
   or sale in question and (z) in the event of a sale of all or substantially
   all of Issuer's assets or deposits, an amount equal to (i) the sum of the
   price paid in such sale for such assets (and/or deposits) and the current
   market value of the remaining assets of Issuer, as determined by a
   nationally-recognized investment banking firm selected by the Holder and
   reasonably acceptable to the Issuer, divided by (ii) the number of shares of
   Issuer Common Stock outstanding at such time.  In the event that a Tender
   Offer or an Exchange Offer is made for Issuer Common Stock or an agreement is
   entered into for a merger or consolidation involving consideration other than
   cash, the value of the securities or other property issuable or deliverable
   in exchange for Issuer Common Stock shall be determined by a nationally-
   recognized investment banking firm selected by Holder and reasonably
   acceptable to the Issuer.

             (4)  "Average Price" shall mean the average closing price of a
                   -------------                                           
   share of Substitute Common Stock for the one year immediately preceding the
   consolidation, merger or sale in question, but in no event higher than the
   closing price of the shares of Substitute Common Stock on the day preceding
   such consolidation, merger or sale; provided that if Issuer is the issuer of
   the Substitute Option, the Average Price shall be computed with respect to a
   share of common stock issued by Issuer, the person merging into Issuer or by
   any company which controls such person, as Holder may elect.

                                      -7-
<PAGE>
 
          (f)  In no event, pursuant to any of the foregoing paragraphs, shall
the Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of Substitute Common Stock outstanding prior to exercise of the
Substitute Option.  In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of Substitute Common Stock
but for the limitation in the first sentence of this Section 7(f), Substitute
Option Issuer shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in the
first sentence of this Section 7(f) over (ii) the value of the Substitute Option
after giving effect to the limitation in the first sentence of this Section
7(f).  This difference in value shall be determined by a nationally-recognized
investment banking firm selected by Holder and reasonably acceptable to the 
Issuer.

          (g)  Issuer shall not enter into any transaction described in Section
7(b) unless the Acquiring Corporation and any person that controls the Acquiring
Corporation assume in writing all the obligations of Issuer hereunder and take
all other actions that may be necessary so that the provisions of this Section 7
are given full force and effect (including, without limitation, any action that
may be necessary so that the holders of the other shares of common stock issued
by Substitute Option Issuer are not entitled to exercise any rights by reason of
the issuance or exercise of the Substitute Option and the shares of Substitute
Common Stock are otherwise in no way distinguishable from or have lesser
economic value (other than any diminution in value resulting from the fact that
the shares of Substitute Common Stock are restricted securities, as defined in
Rule 144 under the Securities Act or any successor provision) than other shares
of common stock issued by Substitute Option Issuer).

          8.  REPURCHASE AT THE OPTION OF HOLDER.

          (a)  At the request of Holder at any time commencing upon the first
occurrence of a Repurchase Event (as defined in Section 8(d)) and ending 12
months immediately thereafter, Issuer shall repurchase from Holder (i) the
Option and (ii) all shares of Issuer Common Stock purchased by Holder pursuant
hereto with respect to which Holder then has beneficial ownership.  The date on
which Holder 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 Purchase Price paid by Holder for any shares of
   Issuer Common Stock acquired pursuant to the Option with respect to which
   Holder then has beneficial ownership;

             (ii)  the excess, if any, of (x) the Applicable Price (as defined
   below) for each share of Issuer Common Stock over (y) the Purchase Price
   (subject to adjustment pursuant to Section 7), multiplied by the number of
   shares of Issuer 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 Holder for each share of
   Issuer Common Stock with respect to which the Option has been exercised and
   with respect to which Holder then has beneficial ownership, multiplied by the
   number of such shares.

                                      -8-
<PAGE>
 
          (b)  If Holder exercises its rights under this Section 8, Issuer
shall, within 10 business days after the Request Date, pay the Section 8
Repurchase Consideration to Holder in immediately available funds, and
contemporaneously with such payment Holder shall surrender to Issuer the Option
and the certificates evidencing the shares of Issuer Common Stock purchased
thereunder with respect to which Holder then has beneficial ownership, and 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 Federal Reserve Board, the Federal Deposit
Insurance Corporation, the Massachusetts Division of Banks or any other
Governmental Entity is required in connection with the payment of all or any
portion of the Section 8 Repurchase Consideration, Holder shall have the ongoing
option to revoke its request for repurchase pursuant to Section 8, in whole or
in part, or to require that Issuer deliver from time to time that portion of the
Section 8 Repurchase Consideration that it is not then so prohibited from paying
and promptly file the required notice or application for approval and
expeditiously process the same (and each party shall cooperate with the
other in the filing of any such notice or application and the obtaining of any
such approval).  If the Federal Reserve Board, the Federal Deposit Insurance
Corporation, the Massachusetts Division of Banks or any other Governmental
Entity disapproves of any part of Issuer's proposed repurchase pursuant to this
Section 8, Issuer shall promptly give notice of such fact to Holder.  If the
Federal Reserve Board, the Federal Deposit Insurance Corporation, the
Massachusetts Division of Banks or any other Governmental Entity prohibits the
repurchase in part but not in whole, then Holder shall have the right (i) to
revoke the repurchase request or (ii) to the extent permitted by the Federal
Reserve Board, the Federal Deposit Insurance Corporation, the Massachusetts
Division of Banks or other Governmental Entity, determine whether the repurchase
should apply to the Option and/or Option Shares and to what extent to each, and
Holder shall thereupon have the right to exercise the Option as to the number of
Option Shares for which the Option was exercisable at the Request Date less the
sum of the number of shares covered by the Option in respect of which payment
has been made pursuant to Section 8(a)(ii) and the number of shares covered by
the portion of the Option (if any) that has been repurchased.  Holder shall
notify Issuer of its determination under the preceding sentence within five
business days of receipt of notice of disapproval of the repurchase. The parties
hereto agree that Issuer's obligations to repurchase the Option or Option Shares
under this Section 8 shall terminate upon the occurrence of an Exercise
Termination Event unless a Purchase Event shall have occurred prior to the
occurrence of an Exercise Termination Event.

          (c)  For purposes of this Agreement, the "Applicable Price" means the
                                                    ----------------           
highest of (i) the highest price per share of Issuer Common Stock paid for any
such share by the person or groups described in Section 8(d)(i), (ii) the price
per share of Issuer Common Stock received by holders of Issuer Common Stock in
connection with any merger or other business combination transaction described
in Section 7(b)(i), 7(b)(ii) or 7(b)(iii), or (iii) the highest closing sales
price per share of Issuer Common Stock quoted on the Nasdaq Stock Market's
National Market ("NASDAQ/NMS") (or if Issuer Common Stock is not quoted on
                  ----------                                              
NASDAQ/NMS, the highest bid price per share as quoted on the principal trading
market or securities exchange on which such shares are traded, as reported by a
recognized source chosen by Holder) during the 60 business days preceding the
Request Date; provided, however, that in the event of a sale of less than all of
Issuer's assets, the Applicable Price shall be the sum of the price paid in such
sale for such assets and the current market value of the remaining assets of
Issuer as determined by a nationally-recognized investment banking firm selected
by Holder and reasonably acceptable to the Issuer, divided by the number of
shares of Issuer Common Stock outstanding at the time of such sale.  If the

                                      -9-
<PAGE>
 
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 Holder and reasonably acceptable
to Issuer, which determination shall be conclusive for all purposes of this
Option.

          (d)  As used herein, a "Repurchase Event" shall occur if (i) any
                                  ----------------                        
person (other than Grantee or any subsidiary of Grantee) shall have acquired
beneficial ownership of (as such term is defined in Rule 13d-3 promulgated under
the Exchange Act), or the right to acquire beneficial ownership of, or any
                                                                          
"group" (as such term is defined in Section 13(d)(3) of the Exchange Act) shall
- ------                                                                         
have been formed which beneficially owns or has the right to acquire beneficial
ownership of, 50% or more of the then outstanding shares of Issuer Common Stock,
or (ii) any of the transactions described in Section 7(b)(i), Section 7(b)(ii)
or Section 7(b)(iii) shall be consummated.

          9.  REGISTRATION RIGHTS.

          (a)  DEMAND REGISTRATION RIGHTS.  Issuer shall, subject to the
conditions of Section 9(c), at the request of Grantee (whether on its own behalf
or on behalf of any subsequent Holder of this Option (or part thereof) or any 
of the shares of Issuer Common Stock issued pursuant hereto), as expeditiously
as possible prepare and file a registration statement under the Securities Act
if such registration is necessary in order to permit the sale or other
disposition of any or all shares of Issuer Common Stock or other securities that
have been acquired by or are issuable to Holder upon exercise of the Option in
accordance with the intended method of sale or other disposition stated by
Holder in such request, including without limitation a "shelf" registration 
                                                        -----
statement under Rule 415 under the Securities Act or any successor provision, 
and Issuer shall use its best efforts to qualify such shares or other 
securities for sale under any applicable state securities laws.

          (b)  ADDITIONAL REGISTRATION RIGHTS.  If Issuer at any time after the
exercise of the Option proposes to register any shares of Issuer Common Stock
under the Securities Act in connection with an underwritten public offering of
such Issuer Common Stock, Issuer will promptly give written notice to Holder of
its intention to do so and, upon the written request of Holder given within 30
days after receipt of any such notice (which request shall specify the number of
shares of Issuer Common Stock intended to be included in such underwritten
public offering by Holder), Issuer will cause all such shares for which a Holder
shall have requested participation in such registration to be so registered and
included in such underwritten public offering;  provided, however, that Issuer
may elect to not cause any such shares to be so registered (i) if the
underwriters in good faith object for valid business reasons, or (ii) in the
case of a registration solely to implement an employee benefit plan or a
registration filed on Form S-4 under the Securities Act or any successor form;
provided, further, however, that such election pursuant to clause (i) may only
be made one time.  If some but not all the shares of Issuer Common Stock with
respect to which Issuer shall have received requests for registration pursuant
to this Section 9(b) shall be excluded from such registration, Issuer shall make
appropriate allocation of shares to be registered among Holders permitted to
register their shares of Issuer Common Stock in connection with such
registration pro rata in the proportion that the number of shares requested to
be registered by each such Holder bears to the total number of shares requested
to be registered by all such Holders then desiring to have Issuer Common Stock
registered for sale.

          (c)  CONDITIONS TO REQUIRED REGISTRATION.  Issuer shall use all
reasonable efforts to cause each registration statement referred to in Section
9(a) to become effective and to obtain all consents or waivers of other parties
which are required therefor and to keep such registration statement 

                                      -10-
<PAGE>
 
effective; provided, however, that Issuer may delay any registration of Option
Shares required pursuant to Section 9(a) for a period not exceeding 90 days if
Issuer shall in good faith determine that any such registration would adversely
affect an offering or contemplated offering of other securities by Issuer, and
Issuer shall not be required to register Option Shares under the Securities Act
pursuant to Section 9(a):

          (i)  prior to the earliest of (A) termination of the Affiliation
   Agreement pursuant to Article XI thereof, and (B) a Purchase Event or a
   Preliminary Purchase Event;
          (ii)  on more than one occasion during any calendar year and on
   more than two occasions in total;

          (iii)  within 90 days after the effective date of a registration
   referred to in Section 9(b) pursuant to which the Holder or Holders concerned
   were afforded the opportunity to register such shares under the Securities
   Act and such shares were registered as requested; and

          (iv)  unless a request therefor is made to Issuer by the Holder or
   Holders of at least 25% or more of the aggregate number of Option Shares
   (including shares of Issuer Common Stock issuable upon exercise of the
   Option) then outstanding.

          In addition to the foregoing, Issuer shall not be required to maintain
the effectiveness of any registration statement after the expiration of nine
months from the effective date of such registration statement.  Issuer shall use
all reasonable efforts to make any filings, and take all steps, under all
applicable state securities laws to the extent necessary to permit the sale or
other disposition of the Option Shares so registered in accordance with the
intended method of distribution for such shares, provided, however, that Issuer
shall not be required to consent to general jurisdiction or to qualify to do
business in any state where it is not otherwise required to so consent to such
jurisdiction or to so qualify to do business. Notwithstanding anything to the
contrary contained herein, in no event shall Issuer be obligated to effect more
than two registrations pursuant to this Section 9 by reason of the fact that
there shall be more than one Holder as a result of any assignment or division of
this Agreement.

          (d)  EXPENSES.  Issuer will pay all expenses (including without
limitation registration fees, qualification fees, blue sky fees and expenses,
accounting expenses, legal expenses and printing expenses incurred by it) in
connection with the first registration pursuant to Section 9(a) or (b) and all
other qualifications, notifications or exemptions pursuant to Section 9(a) or
(b).  Underwriting discounts and commissions relating to Option Shares, fees and
disbursements of counsel to the Holder(s) of Option Shares being registered and
any other expenses incurred by such Holder(s) in connection with any such
registration shall be borne by such Holder(s).

          (e)  INDEMNIFICATION.  In connection with any registration under
Section 9(a) or (b), Issuer hereby indemnifies each Holder, and each underwriter
thereof, including each person, if any, who controls such Holder or underwriter
within the meaning of Section 15 of the Securities Act, against all expenses,
losses, claims, damages and liabilities caused by any untrue, or alleged untrue,
statement of a material fact contained in any registration statement or
prospectus or notification or offering circular (including any amendments or
supplements thereto) or any preliminary prospectus, or caused by any omission,
or alleged omission, to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, except
insofar as such expenses, losses, claims, damages or liabilities of such
indemnified party are caused by any 

                                      -11-
<PAGE>
 
untrue statement or alleged untrue statement that was included by Issuer in any
such registration statement or prospectus or notification or offering circular
(including any amendments or supplements thereto) in reliance upon, and in
conformity with, information furnished in writing to Issuer by such indemnified
party expressly for use therein, and Issuer and each officer, director and
controlling person of Issuer shall be indemnified by such Holder, or by such
underwriter, as the case may be, for all such expenses, losses, claims, damages
and liabilities caused by any untrue, or alleged untrue, statement that was
included by Issuer in any such registration statement or prospectus or
notification or offering circular (including any amendments or supplements
thereto) in reliance upon, and in conformity with, information furnished in
writing to Issuer by such Holder or such underwriter, as the case may be,
expressly for such use.

          Promptly upon receipt by a party indemnified under this Section 9(e)
of notice of the commencement of any action against such indemnified party in
respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 9(e), such indemnified party shall notify
the indemnifying party in writing of the commencement of such action, but,
except to the extent of any actual prejudice to the indemnifying party, the
failure so to notify the indemnifying party shall not relieve it of any
liability which it may otherwise have to any indemnified party under this
Section 9(e).  In case notice of commencement of any such action shall be given
to the indemnifying party as above provided, the indemnifying party shall be
entitled to participate in and, to the extent it may wish, jointly with any
other indemnifying party similarly notified, to assume the defense of such
action at its own expense, with counsel chosen by it and reasonably 
satisfactory to such indemnified party.  The indemnified party shall have the 
right to employ separate counsel in any such action and participate in the 
defense thereof, but the fees and expenses of such counsel (other than
reasonable costs of investigation) shall be paid by the indemnified party unless
(i) the indemnifying party agrees to pay the same, (ii) the indemnifying party
fails to assume the defense of such action with counsel reasonably satisfactory
to the indemnified party, or (iii) the indemnified party has been advised by
counsel that one or more legal defenses may be available to the indemnifying
party that may be contrary to the interest of the indemnified party, in which
case the indemnifying party shall be entitled to assume the defense of such
action notwithstanding its obligation to bear fees and expenses of such counsel.
No indemnifying party shall be liable for any settlement entered into without
its consent, which consent may not be unreasonably withheld.

          If the indemnification provided for in this Section 9(e) is
unavailable to a party otherwise entitled to be indemnified in respect of any
expenses, losses, claims, damages or liabilities referred to herein, then the
indemnifying party, in lieu of indemnifying such party otherwise entitled to be
indemnified, shall contribute to the amount paid or payable by such party to be
indemnified as a result of such expenses, losses, claims, damages or liabilities
in such proportion as is appropriate to reflect the relative benefits received
by Issuer, the selling Holders and the underwriters from the offering of the
securities and also the relative fault of Issuer, the selling Holders and the
underwriters in connection with the statement or omissions which results in such
expenses, losses, claims, damages or liabilities, as well as any other relevant
equitable considerations.  The amount paid or payable by a party as a result of
the expenses, losses, claims, damages and liabilities referred to above shall be
deemed to include any legal or other fees or expenses reasonably incurred by
such party in connection with investigating or defending any action or claim;
provided, however, that in no case shall the selling Holders be responsible, in
the aggregate, for any amount in excess of the net offering proceeds
attributable to its Option Shares included in the offering.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(g) of the

                                      -12-
<PAGE>
 
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  Any obligation by any Holder to
indemnify shall be several and not joint with other Holders.

          In connection with any registration pursuant to Section 9(a) or (b)
above, Issuer and each selling Holder (other than Grantee) shall enter into an
agreement containing the indemnification provisions of this Section 9(e).

          (f)  MISCELLANEOUS REPORTING.  Issuer shall comply with all reporting
requirements and will do all such other things as may be necessary to permit the
expeditious sale at any time of any Option Shares by the Holder(s) in accordance
with and to the extent permitted by any rule or regulation permitting
nonregistered sales of securities promulgated by the Commission from time to
time, including, without limitation, Rule 144A.  Issuer shall at its expense
provide the Holder with any information necessary in connection with the
completion and filing of any reports or forms required to be filed by them under
the Securities Act or the Exchange Act, or required pursuant to any state
securities laws or the rules of any stock exchange.

          (g)  ISSUE TAXES.  Issuer will pay all stamp taxes in connection with
the issuance and the sale of the Option Shares and in connection with the
exercise of the Option, and will save any Holder harmless, without limitation as
to time, against any and all liabilities, with respect to all such taxes.

          10.  QUOTATION; LISTING.  If Issuer Common Stock or any other
securities to be acquired upon exercise of the Option are then authorized for
quotation or trading or listing on NASDAQ/NMS or any securities exchange,
Issuer, upon the request of Holder, will promptly file an application, if
required, to authorize for quotation or trading or listing the shares of Issuer
Common Stock or other securities to be acquired upon exercise of the Option on
NASDAQ/NMS or such other securities exchange and will use its best efforts to
obtain approval, if required, of such quotation or listing as soon as
practicable.

          11.  DIVISION OF OPTION.  Upon the occurrence of a Purchase Event or a
Preliminary Purchase Event, this Agreement (and the Option granted hereby) are
exchangeable, without expense, at the option of Holder, upon presentation and
surrender of this Agreement at the principal office of the Issuer for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Issuer Common
Stock purchasable 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.  Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date.  Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

          12.  MISCELLANEOUS.

          (a)  EXPENSES.  Except as otherwise provided in Section 9, each of 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 financial consultants, investment bankers,
accountants and counsel.

          (b)  WAIVER AND AMENDMENT.  Any provision of this Agreement may be
waived at any time by the party that is entitled to the benefits of such
provision.  This Agreement may not be modified, amended, altered or supplemented
except upon the execution and delivery of a written agreement executed by the
parties hereto.

          (c)  ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES; SEVERABILITY.
This Agreement, together with the Affiliation Agreement and the other documents
and instruments referred to herein and therein, between Grantee and Issuer (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 (other than the indemnified parties under Section 9(e)
and any transferee of the Option Shares or any permitted transferee of this
Agreement pursuant to Section 12(h)) 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 federal or state 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.  If for any reason such court or
regulatory agency determines that the Option does not permit Holder to acquire,
or does not require Issuer to repurchase, the full number of shares of Issuer
Common Stock as provided in Sections 3 and 8 (as adjusted pursuant to Section
7), it is the express intention of Issuer to allow Holder to acquire or to
require Issuer to repurchase such lesser number of shares as may be permissible
without any amendment or modification hereof.

          (d)  GOVERNING LAW.  This Agreement shall be governed and construed in
accordance with the laws of The Commonwealth of Massachusetts without regard to
any applicable conflicts of law rules.

          (e)  DESCRIPTIVE HEADINGS.  The descriptive headings contained herein

Federal Reserve Board.

     (i)  FURTHER ASSURANCES.  In the event of any exercise of the Option by
Holder, Issuer and Holder shall execute and deliver all other documents and
instruments and take all other action that may be reasonably necessary in order
to consummate the transactions provided for by such exercise.

     (j)  SPECIFIC PERFORMANCE.  The parties hereto agree that this Agreement
may be enforced by either party through specific performance, injunctive relief
and other equitable relief.  Both parties further agree to waive any requirement
for the securing or posting of any bond in

connection with the obtaining of any such equitable relief and that this
provision is without prejudice to any other rights that the parties hereto may
have for any failure to perform this Agreement.

     (k) EXTENSION OF EXERCISE TIME PERIODS FOR REGULATORY COMPLIANCE. The time
periods set forth in this Agreement for the exercise by Grantee or the Holder to
exercise its rights with respect to the Option or a Substitute Option or with
respect to repurchase of the Option shall be extended: (i) to the extent
necessary to obtain all regulatory approvals for the exercise of such rights and
for the expiration of all statutory waiting periods; and (ii) to the extent
necessary to avoid liability under Section 16(b) of the 1934 Act by reason of

The 1855 Bancorp
791 Purchase Street
New Bedford, Massachusetts 02741-2101

Ladies and Gentlemen

     The undersigned is a director of Sandwich Bancorp ("Sandwich") and is the
beneficial holder of shares of common stock of Sandwich ("Sandwich Common
Stock").

     Sandwich and The 1855 Bancorp ("1855 Bancorp") are considering the
execution of an Amended and Restated Affiliation and Merger Agreement
("Agreement") contemplating the merger of a newly formed special-purpose
subsidiary of 1855 Bancorp with and into Sandwich, with Sandwich as the
surviving corporation of the merger (the "Merger"), such execution being subject
in the case of 1855 Bancorp to the execution and delivery of this letter
agreement ("letter agreement").  In consideration of the substantial expenses
that 1855 Bancorp will incur in connection with the transactions contemplated by
the Agreement and in order to induce 1855 Bancorp to execute the Agreement and
to proceed to incur such expenses, the undersigned agrees and undertakes, in his
capacity as a shareholder of Sandwich and not in his capacity as a director of
Sandwich, as follows:

     1. The undersigned, while this letter agreement is in effect, shall vote or
cause to be voted all of the Shares of Sandwich Common Stock that the
undersigned shall be entitled to so vote, whether such Shares are beneficially
owned by the undersigned on the date of this letter agreement or are
subsequently acquired, whether pursuant to the exercise of stock options or
otherwise, at the Special Meeting of Sandwich's stockholders to be called and
held following the date hereof, for the approval of the Agreement and the
Merger.

     2.  The undersigned acknowledges and agrees that any remedy at law for
breach of the foregoing provisions shall be inadequate and that, in addition to
any other relief which may be available, 1855 Bancorp shall be entitled to
temporary and permanent injunctive relief without the necessity of proving
actual damages.

     3.  The foregoing restrictions shall not apply to shares with respect to
which the undersigned may have voting power as a fiduciary for others.  In
addition, this letter agreement shall only apply to actions taken by the
undersigned in his capacity as a shareholder of Sandwich and shall not in any
way limit or affect actions the undersigned may take in his capacity as a
director of Sandwich.

     4.  This letter agreement shall automatically terminate upon termination of
the Agreement in accordance with its terms.
<PAGE>
 
     5.  This letter agreement shall supersede the letter agreement between the
undersigned and 1855 Bancorp dated February 2, 1998, which prior letter
agreement is hereby terminated.

     IN WITNESS WHEREOF, the undersigned has executed this Agreement as of the
date first above written.

                                 Very truly yours,


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

                                            March 23, 1998



The 1855 Bancorp
791 Purchase Street
New Bedford, Massachusetts 02741-2101

Gentlemen:


     I have been advised that I might be considered to be an "affiliate" of
Sandwich Bancorp, Inc., a Massachusetts corporation (the "Company"), for
purposes of paragraphs (c) and (d) of Rule 145 of the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the "Act")
and for purposes of generally accepted accounting principles ("GAAP") as such
term relates to pooling of interests accounting treatment for certain business
combinations under GAAP and the interpretations of the SEC or its staff,
including, without limitation, Section 201.01 of the SEC's Codification of
Financial Reporting Policies ("Section 201.01") and the SEC's Staff Accounting
Bulletin No. 65.

     The 1855 Bancorp ("1855 Bancorp") and the Company have entered into an
Amended and Restated Affiliation and Merger Agreement, dated as of March 23,
1998 (the "Merger Agreement").  Upon consummation of the merger contemplated by
the Merger Agreement (the "Merger"), I may receive shares of common stock of
1855 Bancorp ("1855 Bancorp Common Stock") in exchange for my shares of common
stock, par value $1.00 per share, of the Company ("Company Common Stock").  This
agreement is hereinafter referred to as the "Letter Agreement."

     A.  I represent and warrant to, and agree with, 1855 Bancorp as follows:


        1.  I have read this Letter Agreement and the Merger Agreement and have
discussed their requirements and other applicable limitations upon my ability to
sell, pledge, transfer or otherwise dispose of share of 1855 Bancorp Common
Stock, and any other capital stock of 1855 Bancorp and Company Common Stock, to
the extent I felt necessary, with my counsel or counsel for the Company.

        2.  I shall not make any offer, sale, pledge, transfer or other
disposition in violation of the Act or the rules and regulations of the SEC
thereunder of the shares of 1855 Bancorp Common Stock I receive pursuant to the
Merger.


        3.  Notwithstanding the foregoing and any other agreements on my part in
connection with the 1855 Bancorp Common Stock, any other capital stock of 1855
Bancorp 
<PAGE>
 
The 1855 Bancorp
Page 2


and Company Common Stock, I hereby agree that, without the consent of
1855 Bancorp, I will not sell or otherwise reduce my risk relative to any shares
of Company Common Stock, 1855 Bancorp Common Stock or any other capital stock of
1855 Bancorp during the period beginning thirty days prior to the effective date
of the Merger and continuing until financial results covering at least thirty
days of combined operations have been published following the effective date of
the Merger within the meaning of Section 201.01.


     B.  I understand and agree that:

        1.  I have been advised that any issuance of shares of 1855 Bancorp
Common Stock to me pursuant to the Merger will be registered with the SEC.  I
have also been advised, however, that, because I may be an "affiliate" of the
Company at the time the Merger will be submitted for a vote of the stockholders
of the Company and my disposition of such shares has not been registered under
the Act, I must hold such shares indefinitely unless (i) such disposition of
such shares is subject to an effective registration statement and to the
availability of a prospectus under the Act, (ii) a sale of such shares is made
in conformity with the provisions of Rule 145(d) under the Act, (iii) a sale of
such shares is made following expiration of the restrictive period set forth in
Rule 145(d) or (iv) in an opinion of counsel, in form and substance reasonably
satisfactory to 1855 Bancorp, some other exemption from registration is
available with respect to any such proposed disposition of such shares.

        2.  Stop transfer instructions will be given to the transfer agents of
the Company and 1855 Bancorp with respect to the shares of the Company Common
Stock and the shares of 1855 Bancorp Common Stock and any other capital stock in
connection with the restrictions set forth herein, and there will be placed on
the certificate representing shares of 1855 Bancorp Common Stock I receive
pursuant to the Merger, or any certificates delivered in substitution therefor,
a legend stating in substance:


           The shares represented by this certificate were issued in a
           transaction to which Rule 145 under the Securities Act of 1933
           applies.  The shares represented by this certificate may only be
           transferred in accordance with the terms of an agreement between the
           registered holder hereof and The 1855 Bancorp, a copy of which
           agreement is on file at the principal offices of The 1855 Bancorp.  A
           copy of such agreement shall be provided to the holder hereof without
           charge upon receipt by The 1855 Bancorp of a written request.


        3.  Unless a transfer of my shares of 1855 Bancorp Common Stock is a
sale made in conformity with the provisions of Rule 145(d), made following
expiration of the restrictive period set forth in Rule 145(d) or made pursuant
to any effective registration statement under the Act, 1855 Bancorp reserves the
right to put an appropriate legend on the certificate issued to my transferee.
<PAGE>
 
The 1855 Bancorp
Page 3

     It is understood and agreed that this Letter Agreement shall terminate and
be of no further force and effect if the Merger Agreement is terminated in
accordance with its terms.  It is also understood and agreed that this Letter
Agreement shall terminate and be of no further force and effect and the stop
transfer instructions set forth in Paragraph B.2. above shall be lifted
forthwith upon the later of (i) such time as financial results covering at least
thirty days of combined operations following the effective date of the Merger
have been published within the meaning of Section 201.01 and (ii) delivery by
the undersigned to 1855 Bancorp of a copy of a letter from the staff of the SEC,
an opinion of counsel in form and substance reasonably satisfactory to 1855
Bancorp, or other evidence reasonably satisfactory to 1855 Bancorp, to the
effect that a transfer of my shares of 1855 Bancorp Common Stock will not
violate the Act or any of the rules and regulations of the SEC thereunder.  In
addition, it is understood and agreed that the legend set forth in Paragraph
B.2. above shall be removed forthwith from the certificate or certificates
representing my shares of 1855 Bancorp Common Stock upon expiration of the
restrictive period set forth in Rule 145(d) or if I shall have delivered to 1855
Bancorp a copy of a letter from the staff of the SEC, an opinion of counsel in
form and substance reasonably satisfactory to 1855 Bancorp, or other evidence
satisfactory to 1855 Bancorp that a transfer of my shares of 1855 Bancorp Common
Stock represented by such certificate or certificates will be a sale made in
conformity with the provisions of Rule 145(d), or made pursuant to an effective
registration statement under the Act.


        4.  I recognize and agree that the foregoing provisions also apply to
(i) my spouse, (ii) any relative of mine or my spouse=s occupying my home,
(iii), any trust or estate in which I, my spouse or any such relative owns at
least 10% beneficial interest or of which any of us serves as trustee, executor
or in any similar capacity and (iv) any corporation or other organization in
which I, my spouse or any such relative owns at least 10% of any class of equity
securities or of the equity interest.

        5.  I further recognize that in the event I become a director or officer
of 1855 Bancorp upon consummation of the Merger, any sale of 1855 Bancorp stock
by me may be subject to liability pursuant to Section 16 (b) of the Securities
Exchange Act of 1934, as amended.

        6.  Execution of this Letter Agreement should not be construed as an
admission on my part that I am an "affiliate" of the Company as described in the
first paragraph of this Letter Agreement or as a waiver of any rights I may have
to object to any claim that I am such an affiliate on or after the date of this
Letter Agreement.

     Act), or shall have filed a registration statement under the Securities Act
     with respect to, a tender offer or exchange offer to purchase any shares of
     Issuer Common Stock such that, upon consummation of such offer, such person
     would own or control 10% or more of the then outstanding shares of Issuer
     Common Stock (such an offer being referred to herein as a "Tender Offer"

           (C)  Issuer shall have breached any representation, warranty,
        covenant or obligation contained in the Affiliation Agreement and such
        breach would entitle Grantee to terminate the Affiliation Agreement

        regard to the cure period provided for therein unless such cure is
        promptly effected without jeopardizing consummation of the Merger

Issuer a written notice (the date of which being herein referred to as the
                                                                          
"Notice Date") specifying (i) the total number of Option Shares it intends to

the Massachusetts Division of Banks, or any other Governmental Entity is
required in connection with such purchase, Issuer shall cooperate with Grantee
in the filing of the required notice of application for approval and the
obtaining of such approval and the Closing shall occur immediately following
such regulatory approvals (and any mandatory waiting periods). Any exercise of
the Option shall be deemed to occur on the Notice Date relating thereto.

     4.  PAYMENT AND DELIVERY OF CERTIFICATES.

     (a)  On each Closing Date, Holder shall (i) pay to Issuer, in immediately
available funds by wire transfer to a bank account designated by Issuer, an
amount equal to the Purchase Price multiplied by the number of Option Shares to
be purchased on such Closing Date, and (ii) present and surrender this Agreement
to Issuer at the address of Issuer specified in Section 12(f) hereof.

     (b)  At each Closing, simultaneously with the delivery of immediately
available funds and surrender of this Agreement as provided in Section 4(a), (i)
Issuer shall deliver to Holder (A) a certificate or certificates representing
the Option Shares to be purchased at such Closing, which Option Shares shall be
free and clear of all liens, claims, charges and encumbrances of any kind
whatsoever and subject to no preemptive rights, and (B) if the Option is
exercised in part only, an executed new agreement with the same terms as this
Agreement evidencing the right to purchase the balance of the shares of Issuer
Common Stock purchasable hereunder, and (ii) Holder shall deliver to Issuer a
letter agreeing that Holder shall not offer to sell or otherwise dispose of such
Option Shares in violation of applicable federal and state law or of the
provisions of this Agreement.

     (c)  In addition to any other legend that is required by applicable law,
certificates for the Option Shares delivered at each Closing shall be endorsed
with a restrictive legend which shall read substantially as follows:


           THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS SUBJECT
        TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
        AND PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT DATED AS OF MARCH
        23, 1998.  A COPY OF SUCH AGREEMENT WILL BE PROVIDED TO THE HOLDER
        HEREOF WITHOUT CHARGE UPON RECEIPT BY ISSUER OF A WRITTEN REQUEST
        THEREFOR.


It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if Holder shall have delivered to Issuer a copy of a letter from the staff of
the SEC, or an opinion of counsel, in form and substance reasonably satisfactory
to Issuer, to the effect that such legend is not required for purposes of the
1933 Act; (ii) the reference to the provisions to this Agreement in the above
legend shall be removed by delivery of substitute certificate(s) without such
reference if the shares have been sold or transferred in compliance with the
provisions of this Agreement and under circumstances that do not require the
retention of such reference; and (iii) the legend shall be removed in its
entirety if the conditions in the preceding clauses (i) and (ii) are both
satisfied. In addition, such certificates shall bear any other legend as may be
required by law.

                                      -4-
<PAGE>
 
     (d)  Upon the giving by Holder to Issuer of the written notice of exercise
of the Option provided for under Section 3(e), the tender of the applicable
purchase price in immediately available funds and the tender of this Agreement
to Issuer, Holder shall be deemed to be the holder of record of the shares of
Issuer Common Stock issuable upon such exercise, notwithstanding that the stock
transfer books of Issuer shall then be closed or that certificates representing
such shares of Issuer Common Stock shall not then be actually delivered to
Holder.


     (e)  Issuer agrees (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Issuer Common Stock so that the Option may be exercised without additional
authorization of Issuer Common Stock so that the Option may be exercised without
requiring Issuer's stockholders to approve an increase in the number of
authorized shares of Issuer Common Stock after giving effect to all other
options, warrants, convertible securities and other rights to purchase Issuer
Common Stock, (ii) that it will not, by charter amendment or through
reorganization, consolidation, merger, dissolution or sale of assets, or by any
other voluntary act, avoid or seek to avoid the observance or performance of any
of the covenants, stipulations or conditions to be observed or performed
hereunder by Issuer, (iii) promptly to take all action as may from time to time
be required (including (A) complying with all premerger notification, reporting
and waiting period requirements and (B) in the event prior approval of or notice
to any Governmental Entity is necessary before the Option may be exercised,
cooperating fully with Holder in preparing such applications or notices and
providing such information to such Governmental Entity as it may require) in
order to permit Holder to exercise the Option and Issuer duly and effectively to
issue shares of Issuer Common Stock pursuant hereto, and (iv) promptly to take
all action provided herein to protect the rights of Holder against dilution.

warrants to Grantee (and Holder, if different than Grantee) as follows:

     (b)  NO VIOLATIONS.  The execution and delivery of this Agreement, the
consummation of the transactions contemplated hereby and compliance by Issuer
with any of the provisions hereof will not (i) conflict with or result in a
breach of any provision of its Articles of Organization or Bylaws or a default
(or give rise to any right of termination, cancellation or acceleration) under
any of the terms, conditions or provisions of any note, bond, debenture,
mortgage, indenture, license, material agreement or other material instrument or
obligation to which Issuer is a party, or by which it or any of its properties

assets.

     (c)  AUTHORIZED STOCK.  Issuer has taken all necessary corporate and other

Issuer Common Stock equal to the maximum number of shares of Issuer Common Stock
at any time and from time to time purchasable upon exercise of the Option, and
all such shares, upon issuance pursuant to the Option, will be duly and validly
issued, fully paid and nonassessable, and will be delivered free and clear of
all liens, claims, charges and encumbrances of any kind or nature whatsoever and
not subject to any preemptive rights.

     6.  REPRESENTATIONS AND WARRANTIES OF GRANTEE.  Grantee hereby represents
and warrants to Issuer as follows:

     (a) CORPORATE POWER AND AUTHORITY.  Grantee has all requisite corporate
power and authority to enter into this Agreement and, subject to any approvals
or consents referred to herein, to consummate the transactions contemplated
hereby.  The execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby have been duly authorized by all necessary

otherwise disposed of except in a transaction registered or exempt from

     7.  ADJUSTMENT UPON CHANGES IN ISSUER CAPITALIZATION, ETC.

     (a)  In the event of any change in Issuer Common Stock by reason of a stock
dividend, stock split, split-up, recapitalization, combination, exchange of
shares or similar transaction, the type and number of shares or securities
subject to the Option, and the Purchase Price therefor, shall be adjusted
appropriately, and proper provision shall be made in the agreements governing
such transactions so that Holder shall receive, upon exercise of the Option, the
number and class of shares or other securities or property that Holder would
have received in respect of Issuer Common Stock if the Option had been exercised
immediately prior to such event, or the record date therefor, as applicable.  If
any additional shares of Issuer Common Stock are issued after the date of this
Agreement (other than pursuant to an event described in the first sentence of
this Section 7(a)), the number of shares of Issuer Common Stock subject to the
Option shall be adjusted so that, after such issuance, it, together with any
shares of Issuer Common Stock previously issued pursuant hereto, equals 19.9% of
the number of shares of Issuer Common Stock then issued and outstanding, without
giving effect to any shares subject to or issued pursuant to the Option.

     (b)  In the event that Issuer shall enter into an agreement:  (i) to
consolidate with or merge into any person, other than Grantee or one of its
subsidiaries, and shall not be the continuing or surviving corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Issuer Common Stock shall be changed into or exchanged for stock or
other securities of Issuer or any other person or cash or any other property or
the outstanding shares of Issuer Common Stock immediately prior to such merger
shall after such merger represent less than 50% of the outstanding shares and
share equivalents of the merged company, or (iii) to sell or otherwise transfer
all or substantially all of its assets to any person, other than Grantee or one
of its subsidiaries, then, and in each such case, the 

                                      -6-
<PAGE>
 
agreement governing such transaction shall make proper provisions so that the
Option shall, upon the consummation of any such transaction and upon the terms
and conditions set forth herein, be converted into, or exchanged for, an option
(the "Substitute Option"), at the election of Holder, of any of (x) the 
      -----------------
Acquiring Corporation (as hereinafter defined), (y) any person that controls 
the Acquiring Corporation or (z) in the case of a merger described in clause 
(ii), Issuer (such person being referred to as "Substitute Option Issuer").

     (c)  The Substitute Option shall have the same terms as the Option,
provided that, if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to Holder.  Substitute Option Issuer also shall enter
into an agreement with Holder in substantially the same form as this Agreement,
which shall be applicable to the Substitute Option.

     (d)  The Substitute Option shall be exercisable for such number of shares
of Substitute Common Stock (as hereinafter defined) as is equal to the Assigned
Value (as hereinafter defined) multiplied by the number of shares of Issuer
Common Stock for which the Option was theretofore exercisable, divided by the
Average Price (as hereinafter defined).  The exercise price of Substitute Option
per share of Substitute Common Stock (the "Substitute Option Price") shall then
                                           -----------------------             
be equal to the Purchase Price multiplied by a fraction in which the numerator
is the number of shares of Issuer Common Stock for which the Option was
theretofore exercisable and the denominator is the number of shares of the
Substitute Common Stock for which the Substitute Option is exercisable.

     corporation of a consolidation or merger with Issuer (if other than
     Issuer), (ii) Issuer in a merger in which Issuer is the continuing or

        (2)  "Substitute Common Stock" shall mean the shares of capital stock
              -----------------------                                        
     (or similar equity interest) with the greatest voting power in respect of
     the election of directors (or persons similarly responsible for the
     direction of the business and affairs) of the Substitute Option Issuer.

        (3)  "Assigned Value" shall mean the highest of (w) the price per share
              --------------

     therefor has been made (other than by Holder), (x) the price per share of
     Issuer Common Stock to be paid by any third party pursuant to an agreement

     determined by a nationally-recognized investment banking firm selected by
     the Holder and reasonably acceptable to the Issuer, divided by (ii) the
     number of shares of Issuer Common Stock outstanding at such time.  In the
     event that a Tender Offer or an Exchange Offer is made for Issuer Common
     Stock or an agreement is entered into for a merger or consolidation
     involving consideration other than cash, the value of the securities or
     other property issuable or deliverable in exchange for Issuer Common Stock
     shall be determined 

                                      -7-

              -------------                                                    
     Substitute Common Stock for the one year immediately preceding the
     consolidation, merger or sale in question, but in no event higher than the
     closing price of the shares of Substitute Common Stock on the day preceding
     such consolidation, merger or sale; provided that if Issuer is the issuer
     of the Substitute Option, the Average Price shall be computed with respect
     to a share of common stock issued by Issuer, the person merging into Issuer
     or by any company which controls such person, as Holder may elect.


     (f)  In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the aggregate of the
shares of Substitute Common Stock outstanding prior to exercise of the
Substitute Option.  In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of Substitute Common Stock
but for the limitation in the first sentence of this Section 7(f), Substitute
Option Issuer shall make a cash payment to Holder equal to the excess of (i) the
value of the Substitute Option without giving effect to the limitation in the
first sentence of this Section 7(f) over (ii) the value of the Substitute Option
after giving effect to the limitation in the first sentence of this Section
7(f).  This difference in value shall be determined by a nationally-recognized
investment banking firm selected by Holder and reasonably acceptable to the
Issuer.

     (g)  Issuer shall not enter into any transaction described in Section 7(b)
unless the Acquiring Corporation and any person that controls the Acquiring
Corporation assume in writing all the obligations of Issuer hereunder and take
all other actions that may be necessary so that the provisions of this Section 7
are given full force and effect (including, without limitation, any action that
may be necessary so that the holders of the other shares of common stock issued
by Substitute Option Issuer are not entitled to exercise any rights by reason of
the issuance or exercise of the Substitute Option and the shares of Substitute
Common Stock are otherwise in no way distinguishable from or have lesser
economic value (other than any diminution in value resulting from the fact that
the shares of Substitute Common Stock are restricted securities, as defined in
Rule 144 under the Securities Act or any successor provision) than other shares
of common stock issued by Substitute Option Issuer).

     8.  REPURCHASE AT THE OPTION OF HOLDER.

     (a)  At the request of Holder at any time commencing upon the first
occurrence of a Repurchase Event (as defined in Section 8(d)) and ending 12
months immediately thereafter, Issuer shall repurchase from Holder (i) the
Option and (ii) all shares of Issuer Common Stock purchased by Holder pursuant
hereto with respect to which Holder then has beneficial ownership.  The date on
which Holder 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 Purchase Price paid by Holder for any shares of
     Issuer Common Stock acquired pursuant to the Option with respect to which
     Holder then has beneficial ownership;

                                      -8-
<PAGE>
 
        (ii)  the excess, if any, of (x) the Applicable Price (as defined below)
     for each share of Issuer Common Stock over (y) the Purchase Price (subject
     to adjustment pursuant to Section 7), multiplied by the number of shares of
     Issuer 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 Holder for each share of
     Issuer Common Stock with respect to which the Option has been exercised and
     with respect to which Holder then has beneficial ownership, multiplied by
     the number of such shares.


     (b)  If Holder exercises its rights under this Section 8, Issuer shall,
within 10 business days after the Request Date, pay the Section 8 Repurchase
Consideration to Holder in immediately available funds, and contemporaneously
with such payment Holder shall surrender to Issuer the Option and the
certificates evidencing the shares of Issuer Common Stock purchased thereunder
with respect to which Holder then has beneficial ownership, and 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 Federal Reserve Board, the Federal Deposit
Insurance Corporation, the Massachusetts Division of Banks or any other
Governmental Entity is required in connection with the payment of all or any
portion of the Section 8 Repurchase Consideration, Holder shall have the ongoing
option to revoke its request for repurchase pursuant to Section 8, in whole or
in part, or to require that Issuer deliver from time to time that portion of the
Section 8 Repurchase Consideration that it is not then so prohibited from paying
and promptly file the required notice or application for approval and
expeditiously process the same (and each party shall cooperate with the other in
the filing of any such notice or application and the obtaining of any such
approval).  If the Federal Reserve Board, the Federal Deposit Insurance
Corporation, the Massachusetts Division of Banks or any other Governmental
Entity disapproves of any part of Issuer's proposed repurchase pursuant to this
Section 8, Issuer shall promptly give notice of such fact to Holder.  If the
Federal Reserve Board, the Federal Deposit Insurance Corporation, the
Massachusetts Division of Banks or any other Governmental Entity prohibits the
repurchase in part but not in whole, then Holder shall have the right (i) to
revoke the repurchase request or (ii) to the extent permitted by the Federal
Reserve Board, the Federal Deposit Insurance Corporation, the Massachusetts
Division of Banks or other Governmental Entity, determine whether the repurchase
should apply to the Option and/or Option Shares and to what extent to each, and
Holder shall thereupon have the right to exercise the Option as to the number of
Option Shares for which the Option was exercisable at the Request Date less the
sum of the number of shares covered by the Option in respect of which payment
has been made pursuant to Section 8(a)(ii) and the number of shares covered by
the portion of the Option (if any) that has been repurchased.  Holder shall
notify Issuer of its determination under the preceding sentence within five
business days of receipt of notice of disapproval of the repurchase. The parties
hereto agree that Issuer's obligations to repurchase the Option or Option Shares
under this Section 8 shall terminate upon the occurrence of an Exercise
Termination Event unless a Purchase Event shall have occurred prior to the
occurrence of an Exercise Termination Event.

                                      -9-

     (c)  For purposes of this Agreement, the "Applicable Price" means the
                                               ----------------           
highest of (i) the highest price per share of Issuer Common Stock paid for any
such share by the person or groups described in Section 8(d)(i), (ii) the price
per share of Issuer Common Stock received by holders of Issuer Common Stock in
connection with any merger or other business combination transaction described
in Section 7(b)(i), 7(b)(ii) or 7(b)(iii), or (iii) the highest closing sales
price per share of Issuer Common Stock quoted on the Nasdaq Stock Market's
National Market ("NASDAQ/NMS") (or if Issuer Common Stock is not quoted on
                  ----------                                              
NASDAQ/NMS, the highest bid price per share as quoted on the principal trading
market or securities exchange on which such shares are traded, as reported by a
recognized source chosen by Holder) during the 60 business days preceding the
Request Date; provided, however, that in the event of a sale of less than all of
Issuer's assets, the Applicable Price shall be the sum of the price paid in such
sale for such assets and the current market value of the remaining assets of
Issuer as determined by a nationally-recognized investment banking firm selected
by Holder and reasonably acceptable to the Issuer, divided by the number of
shares of Issuer Common Stock outstanding at the time of such sale.  If the
consideration to be offered, paid or received pursuant to either of the
foregoing clauses (i) or (ii) shall be other than in cash, the value of such
consideration shall be determined in good faith by an independent nationally-
recognized investment banking firm selected by Holder and reasonably acceptable
to Issuer, which determination shall be conclusive for all purposes of this
Option.

     (d)  As used herein, a "Repurchase Event" shall occur if (i) any person
                             ----------------                               
(other than Grantee or any subsidiary of Grantee) shall have acquired beneficial
ownership of (as such term is defined in Rule 13d-3 promulgated under the
Exchange Act), or the right to acquire beneficial ownership of, or any "group"
                                                                        ----- 
(as such term is defined in Section 13(d)(3) of the Exchange Act) shall have
been formed which beneficially owns or has the right to acquire beneficial
ownership of, 50% or more of the then outstanding shares of Issuer Common Stock,
or (ii) any of the transactions described in Section 7(b)(i), Section 7(b)(ii)
or Section 7(b)(iii) shall be consummated.

     9.  REGISTRATION RIGHTS.

     (a)  DEMAND REGISTRATION RIGHTS.  Issuer shall, subject to the conditions
of Section 9(c), at the request of Grantee (whether on its own behalf or on
behalf of any subsequent Holder of this Option (or part thereof) or any of the
shares of Issuer Common Stock issued pursuant hereto), as expeditiously as
possible prepare and file a registration statement under the Securities Act if
such registration is necessary in order to permit the sale or other disposition
of any or all shares of Issuer Common Stock or other securities that have been
acquired by or are issuable to Holder upon exercise of the Option in accordance
with the intended method of sale or other disposition stated by Holder in such
request, including without limitation a "shelf" registration statement under
                                         -----                              
Rule 415 under the Securities Act or any successor provision, and Issuer shall
use its best efforts to qualify such shares or other securities for sale under
any applicable state securities laws.


     (b)  ADDITIONAL REGISTRATION RIGHTS.  If Issuer at any time after the
exercise of the Option proposes to register any shares of Issuer Common Stock
under the Securities Act in connection with an underwritten public offering of
such Issuer Common Stock, Issuer will promptly give written notice to Holder of
its intention to do so and, upon the written request of Holder given within 30
days after receipt of any such notice (which request shall specify the number of
shares of Issuer Common Stock intended to be included in such underwritten
public offering by Holder), Issuer will cause all such shares for which a Holder
shall have requested participation in such registration to be 

                                      -10-
<PAGE>
 
so registered and included in such underwritten public offering; provided,
however, that Issuer may elect to not cause any such shares to be so registered
(i) if the underwriters in good faith object for valid business reasons, or (ii)
in the case of a registration solely to implement an employee benefit plan or a
registration filed on Form S-4 under the Securities Act or any successor form;
provided, further, however, that such election pursuant to clause (i) may only
be made one time. If some but not all the shares of Issuer Common Stock with
respect to which Issuer shall have received requests for registration pursuant
to this Section 9(b) shall be excluded from such registration, Issuer shall make
appropriate allocation of shares to be registered among Holders permitted to
register their shares of Issuer Common Stock in connection with such
registration pro rata in the proportion that the number of shares requested to
be registered by each such Holder bears to the total number of shares requested
to be registered by all such Holders then desiring to have Issuer Common Stock
registered for sale.

     (c)  CONDITIONS TO REQUIRED REGISTRATION.  Issuer shall use all reasonable
efforts to cause each registration statement referred to in Section 9(a) to
become effective and to obtain all consents or waivers of other parties which
are required therefor and to keep such registration statement effective;
provided, however, that Issuer may delay any registration of Option Shares
required pursuant to Section 9(a) for a period not exceeding 90 days if Issuer
shall in good faith determine that any such registration would adversely affect
an offering or contemplated offering of other securities by Issuer, and Issuer
shall not be required to register Option Shares under the Securities Act
pursuant to Section 9(a):


        (i)  prior to the earliest of (A) termination of the Affiliation
     Agreement pursuant to Article XI thereof, and (B) a Purchase Event or a
     Preliminary Purchase Event;

        (ii)  on more than one occasion during any calendar year and on more
     than two occasions in total;

        (iii)  within 90 days after the effective date of a registration
     referred to in Section 9(b) pursuant to which the Holder or Holders
     concerned were afforded the opportunity to register such shares under the
     Securities Act and such shares were registered as requested; and

        (iv)  unless a request therefor is made to Issuer by the Holder or
     Holders of at least 25% or more of the aggregate number of Option Shares
     (including shares of Issuer Common Stock issuable upon exercise of the
     Option) then outstanding.


     In addition to the foregoing, Issuer shall not be required to maintain the
effectiveness of any registration statement after the expiration of nine months
from the effective date of such registration statement.  Issuer shall use all
reasonable efforts to make any filings, and take all steps, under all applicable
state securities laws to the extent necessary to permit the sale or other
disposition of the Option Shares so registered in accordance with the intended
method of distribution for such shares, provided, however, that Issuer shall not
be required to consent to general jurisdiction or to qualify to do business in
any state where it is not otherwise required to so consent to such jurisdiction
or to so qualify to do business. Notwithstanding anything to the contrary
contained herein, in no event shall Issuer be obligated to effect more than two
registrations pursuant to this Section 9 by reason of the fact that there shall
be more than one Holder as a result of any assignment or division of this
Agreement.

                                      -11-
<PAGE>
 
     (d)  EXPENSES.  Issuer will pay all expenses (including without limitation
registration fees, qualification fees, blue sky fees and expenses, accounting
expenses, legal expenses and printing expenses incurred by it) in connection
with the first registration pursuant to Section 9(a) or (b) and all other
qualifications, notifications or exemptions pursuant to Section 9(a) or (b).
Underwriting discounts and commissions relating to Option Shares, fees and
disbursements of counsel to the Holder(s) of Option Shares being registered and
any other expenses incurred by such Holder(s) in connection with any such
registration shall be borne by such Holder(s).

     (e)  INDEMNIFICATION.  In connection with any registration under Section
9(a) or (b), Issuer hereby indemnifies each Holder, and each underwriter
thereof, including each person, if any, who controls such Holder or underwriter
within the meaning of Section 15 of the Securities Act, against all expenses,
losses, claims, damages and liabilities caused by any untrue, or alleged untrue,
statement of a material fact contained in any registration statement or
prospectus or notification or offering circular (including any amendments or
supplements thereto) or any preliminary prospectus, or caused by any omission,
or alleged omission, to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, except
insofar as such expenses, losses, claims, damages or liabilities of such
indemnified party are caused by any untrue statement or alleged untrue statement
that was included by Issuer in any such registration statement or prospectus or
notification or offering circular (including any amendments or supplements
thereto) in reliance upon, and in conformity with, information furnished in
writing to Issuer by such indemnified party expressly for use therein, and
Issuer and each officer, director and controlling person of Issuer shall be
indemnified by such Holder, or by such underwriter, as the case may be, for all
such expenses, losses, claims, damages and liabilities caused by any untrue, or
alleged untrue, statement that was included by Issuer in any such registration
statement or prospectus or notification or offering circular (including any
amendments or supplements thereto) in reliance upon, and in conformity with,
information furnished in writing to Issuer by such Holder or such underwriter,
as the case may be, expressly for such use.

     Promptly upon receipt by a party indemnified under this Section 9(e) of
notice of the commencement of any action against such indemnified party in
respect of which indemnity or reimbursement may be sought against any
indemnifying party under this Section 9(e), such indemnified party shall notify
the indemnifying party in writing of the commencement of such action, but,
except to the extent of any actual prejudice to the indemnifying party, the
failure so to notify the indemnifying party shall not relieve it of any
liability which it may otherwise have to any indemnified party under this
Section 9(e).  In case notice of commencement of any such action shall be given
to the indemnifying party as above provided, the indemnifying party shall be
entitled to participate in and, to the extent it may wish, jointly with any
other indemnifying party similarly notified, to assume the defense of such
action at its own expense, with counsel chosen by it and reasonably satisfactory
to such indemnified party.  The indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel (other than reasonable costs of
investigation) shall be paid by the indemnified party unless (i) the
indemnifying party agrees to pay the same, (ii) the indemnifying party fails to
assume the defense of such action with counsel reasonably satisfactory to the
indemnified party, or (iii) the indemnified party has been advised by counsel
that one or more legal defenses may be available to the indemnifying party that
may be contrary to the interest of the indemnified party, in which case the
indemnifying party shall be entitled to assume the defense of 

                                      -12-
<PAGE>
 
such action notwithstanding its obligation to bear fees and expenses of such
counsel. No indemnifying party shall be liable for any settlement entered into
without its consent, which consent may not be unreasonably withheld.

     If the indemnification provided for in this Section 9(e) is unavailable to
a party otherwise entitled to be indemnified in respect of any expenses, losses,
claims, damages or liabilities referred to herein, then the indemnifying party,
in lieu of indemnifying such party otherwise entitled to be indemnified, shall
contribute to the amount paid or payable by such party to be indemnified as a
result of such expenses, losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative benefits received by
Issuer, the selling Holders and the underwriters from the offering of the
securities and also the relative fault of Issuer, the selling Holders and the
underwriters in connection with the statement or omissions which results in such
expenses, losses, claims, damages or liabilities, as well as any other relevant
equitable considerations.  The amount paid or payable by a party as a result of
the expenses, losses, claims, damages and liabilities referred to above shall be
deemed to include any legal or other fees or expenses reasonably incurred by
such party in connection with investigating or defending any action or claim;
provided, however, that in no case shall the selling Holders be responsible, in
the aggregate, for any amount in excess of the net offering proceeds
attributable to its Option Shares included in the offering.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(g) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  Any obligation by any Holder to
indemnify shall be several and not joint with other Holders.

     In connection with any registration pursuant to Section 9(a) or (b) above,
Issuer and each selling Holder (other than Grantee) shall enter into an
agreement containing the indemnification provisions of this Section 9(e).

     (f)  MISCELLANEOUS REPORTING.  Issuer shall comply with all reporting
requirements and will do all such other things as may be necessary to permit the
expeditious sale at any time of any Option Shares by the Holder(s) in accordance
with and to the extent permitted by any rule or regulation permitting
nonregistered sales of securities promulgated by the Commission from time to
time, including, without limitation, Rule 144A.  Issuer shall at its expense
provide the Holder with any information necessary in connection with the
completion and filing of any reports or forms required to be filed by them under
the Securities Act or the Exchange Act, or required pursuant to any state
securities laws or the rules of any stock exchange.

     (g)  ISSUE TAXES.  Issuer will pay all stamp taxes in connection with the
issuance and the sale of the Option Shares and in connection with the exercise
of the Option, and will save any Holder harmless, without limitation as to time,
against any and all liabilities, with respect to all such taxes.

     10.  QUOTATION; LISTING.  If Issuer Common Stock or any other securities to
be acquired upon exercise of the Option are then authorized for quotation or
trading or listing on NASDAQ/NMS or any securities exchange, Issuer, upon the
request of Holder, will promptly file an application, if required, to authorize
for quotation or trading or listing the shares of Issuer Common Stock or other
securities to be acquired upon exercise of the Option on NASDAQ/NMS  or such
other securities exchange and will use its best efforts to obtain approval, if
required, of such quotation or listing as soon as practicable.

                                      -13-
<PAGE>
 
     11.  DIVISION OF OPTION.  Upon the occurrence of a Purchase Event or a
Preliminary Purchase Event, this Agreement (and the Option granted hereby) are
exchangeable, without expense, at the option of Holder, upon presentation and
surrender of this Agreement at the principal office of the Issuer for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Issuer Common
Stock purchasable 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.  Upon receipt by Issuer of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date.  Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

     12.  MISCELLANEOUS.

     (a)  EXPENSES.  Except as otherwise provided in Section 9, each of 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 financial consultants, investment bankers,
accountants and counsel.

     (b)  WAIVER AND AMENDMENT.  Any provision of this Agreement may be waived
at any time by the party that is entitled to the benefits of such provision.
This Agreement may not be modified, amended, altered or supplemented except upon
the execution and delivery of a written agreement executed by the parties
hereto.

     (c)  ENTIRE AGREEMENT; NO THIRD PARTY BENEFICIARIES; SEVERABILITY.  This
Agreement, together with the Affiliation Agreement and the other documents and
instruments referred to herein and therein, between Grantee and Issuer (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 (other than the indemnified parties under Section 9(e)
and any transferee of the Option Shares or any permitted transferee of this
Agreement pursuant to Section 12(h)) 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 federal or state 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.  If for any reason such court or
regulatory agency determines that the Option does not permit Holder to acquire,
or does not require Issuer to repurchase, the full number of shares of Issuer
Common Stock as provided in Sections 3 and 8 (as adjusted pursuant to Section
7), it is the express intention of Issuer to allow Holder to acquire or to
require Issuer to repurchase such lesser number of shares as may be permissible
without any amendment or modification hereof.

     (d)  GOVERNING LAW.  This Agreement shall be governed and construed in
accordance with the laws of The Commonwealth of Massachusetts without regard to
any applicable conflicts of law rules.

     (g)  COUNTERPARTS.  This Agreement and any amendments hereto may be
executed in two counterparts, each of which shall be considered one and the same
agreement and shall become effective when both counterparts have been signed, it

                                  ARTICLE IV

                         DESCRIPTION OF CAPITAL STOCK

     The aggregate number of shares of all classes of capital stock which the
Corporation has authority to issue is 20,000,000, of which 15,000,000 are to be
shares of common stock, $1.00 par value per share, and of which 5,000,000 are to
be shares of serial preferred stock, $1.00 par value per share.  The shares may
be issued by the Corporation from time to time as approved by the Board of
Directors of the Corporation without the approval of the stockholders except as
otherwise provided in this Article IV or the rules of a national securities
exchange or registered securities association if applicable.  The consideration
for the issuance of the shares shall be paid to or received by the Corporation
in full before their issuance and shall not be less than the par value per
share.  The consideration for the issuance of the shares shall be cash, services
rendered, personal property (tangible or intangible), real property, leases of
real property or any other consideration deemed appropriate by the Board of
Directors.  In the absence of actual fraud in the transaction, the judgment of
the Board of Directors as to the value of such consideration shall be
conclusive.  Upon payment of such consideration, such shares shall be deemed to
be fully paid and nonassessable.  In the case of a stock dividend, the part 

                                      -1-
<PAGE>
 
of the surplus of the Corporation which is transferred to stated capital upon
the issuance of shares as a stock dividend shall be deemed to be the
consideration for their issuance.

     A description of the different classes and series (if any) of the
Corporation's capital stock, and a statement of the relative powers,
designations, preferences and rights of the shares of each class and series (if
any) of capital stock, and the qualifications, limitations or restrictions
thereof, are as follows:

     A.   COMMON STOCK.  Except as provided in these Articles (or in any
certificate of establishment of series of preferred stock), the holders of the
common stock shall exclusively possess all voting power.  Each holder of shares
of common stock shall be entitled to one vote for each share held by such
holder.

     Whenever there shall have been paid, or declared and set aside for payment,
to the holders of the outstanding shares of any class of stock having preference
over the common stock as to the payment of dividends, the full amount of
dividends and sinking fund or retirement fund or other retirement payments, if
any, to which such holders are respectively entitled in preference to the common
stock, then dividends may be paid on the common stock, and on any class or
series of stock entitled to participate therewith as to dividends, out of any
assets legally available for the payment of dividends, but only when and as
declared by the Board of Directors of the Corporation.

     In the event of any liquidation, dissolution or winding up of the
Corporation, after there shall have been paid, or declared and set aside for
payment, to the holders of the outstanding shares of any class having preference
over the common stock in any such event the full preferential amounts to which
they are respectively entitled, the holders of the common stock and of any class
or series of stock entitled to participate therewith, in whole or in part, as to
distribution of assets shall be entitled, after payment or provision for payment
of all debts and liabilities of the Corporation, to receive the remaining assets
of the Corporation available for distribution, in cash or in kind.

     Each share of common stock shall have the same relative powers, preferences
and rights as, and shall be identical in all respects with, all the other shares
of common stock of the Corporation.

     B.   SERIAL PREFERRED STOCK.  Subject to any limitations prescribed by law
or these Articles, the Board of Directors of the Corporation is authorized, by
vote from time to time taken, to provide for the issuance of serial preferred
stock in one or more series and to fix and state the powers, designations,
preferences and relative, participating, optional or other special rights of the
shares of each such series, and the qualifications, limitations or restrictions
thereof, including, but not limited to, the determination of any of the
following:

          1.  the distinctive serial designation and the number of shares
     constituting such series; and

          2.  the dividend rates or the amount of dividends to be paid on the
     shares of such series, whether dividends shall be cumulative and, if so,
     from which date or dates, the payment date or dates for dividends, and the
     participating or other special rights, if any, with respect to dividends;
     and

          3.  the voting powers, full or limited, if any, of the shares of such
     series; and

          4.  whether the shares of such series shall be redeemable and, if so,
     the price or prices at which, and the terms and conditions upon which such
     shares may be redeemed; and

          5.  the amount or amounts payable upon the shares of such series in
     the event of voluntary or involuntary liquidation, dissolution or winding
     up of the Corporation; and

          6.  whether the shares of such series shall be entitled to the
     benefits of a sinking or retirement fund to be applied to the purchase or
     redemption of such shares, and, if so entitled, the amount of such fund 

                                      -2-
<PAGE>
 
     and the manner of its application, including the price or prices at which
     such shares may be redeemed or purchased through the application of such
     fund; and

          7.  whether the shares of such series shall be convertible into, or
     exchangeable for, shares of any other class or classes or any other series
     of the same or any other class of classes of stock of the Corporation and,
     if so convertible or exchangeable, the conversion price or prices, or the
     rate or rates of exchange, and the adjustments thereof, if any, at which
     such conversion or exchange may be made, and any other terms and conditions
     of such conversion or exchange; and

          8.  the subscription or purchase price and form of consideration for
     which the shares of such series shall be issued; and

          9.  whether the shares of such series which are redeemed or converted
     shall have the status of authorized but unissued shares of serial preferred
     stock and whether such shares may be reissued as shares of the same or any
     other series of serial preferred stock.

     Any establishment of a series of preferred stock by the Board of Directors
shall become effective when the Corporation files with the Secretary of State of
the Commonwealth of Massachusetts a certificate of establishment of series of
preferred stock, signed under the penalties of perjury by the Chairman of the
Board, the President or any Vice President and by the Clerk or an Assistant
Clerk, setting forth the text of the vote of the Board of Directors determining
the terms of the class or the number of shares and the terms of any series, the
date of adoption of such vote and a certification that such vote was duly
adopted by the Board of Directors of the Corporation.

     Each share of each series of serial preferred stock shall have the same
relative powers, preferences and rights as, and shall be identical in all
respects with, all the other shares of the Corporation of the same series.


                                   ARTICLE V

     The restrictions, if any, imposed by the Articles of Organization upon the
transfer of shares of stock of any class are:

     None, however, see ARTICLE VI(L), "Approval of Certain Business
Combinations."


                                  ARTICLE VI

     Other lawful provisions, for the conduct and regulation of business and
affairs of the Corporation, for its voluntary dissolution or for limiting,
defining or regulating the powers of the Corporation, or of its directors or
stockholders, or of any class of stockholders are as follows:


                                 ARTICLE VI(A)

                               PREEMPTIVE RIGHTS

     No holder of any of the shares of any class or series of stock or of
options, warrants or other rights to purchase shares of any class or series of
stock or of other securities of the Corporation shall have any preemptive right
to purchase or subscribe for any unissued stock of any class or series, or any
unissued bonds, charters of indebtedness, debentures or other securities
convertible into or exchangeable for stock of any class or series or carrying
any right to purchase stock of any class or series; but any such unissued stock,
bonds, charters or indebtedness, debentures or other securities

                                      -3-
<PAGE>
 
convertible into or exchangeable for stock or carrying any right to purchase
stock may be issued pursuant to a vote of the Board of Directors of the
Corporation to such persons, firms, corporations or associations, whether or not
holders thereof, and upon such terms as may be deemed advisable by the Board of
Directors in the exercise of its sole discretion.

                                 ARTICLE VI(B)

                             REPURCHASE OF SHARES

     The Corporation may from time to time, pursuant to authorization by the
Board of Directors of the Corporation and without action by the stockholders,
purchase or otherwise acquire shares of any class, bonds, debentures, notes,
scrip, warrants, obligations, evidences of indebtedness, or other securities of
the Corporation in such manner, upon such terms, and in such amounts as the
Board of Directors shall determine; subject, however, to such limitations or
restrictions, if any, as are contained in the express terms of any class of
shares of the Corporation outstanding at the time of the purchase or acquisition
in question or as are imposed by applicable law.

                                 ARTICLE VI(C)

                  MEETINGS OF STOCKHOLDERS; CUMULATIVE VOTING

     A.   Notwithstanding any other provision of these Articles or the Bylaws of
the Corporation, no action required to be taken or which may be taken at any
annual or special meeting of stockholders of the Corporation may be taken
without a meeting, unless all stockholders entitled to vote on the matter
consent to the action in writing and the written consents are filed with the
records of the meetings of stockholders.  Such consent shall be treated for all
purposes as a vote at a meeting.

     B.   Special meetings of the stockholders of the Corporation for any
purpose or purposes may be called at any time by the Board of Directors of the
Corporation, the President of the Corporation or a committee of the Board of
Directors which has been duly designated by the Board of Directors and whose
powers and authorities, as provided in a vote of the Board of Directors or in
the Bylaws of the Corporation, include the power and authority to call such
special meetings.  Such special meetings may not be called by any other person
or persons, except to the extent the Massachusetts Business Corporation Law
requires corporations that do not have a class of voting stock registered
pursuant to the Securities Exchange Act of 1934 to call a special meeting upon
written application of one or more stockholders who hold at least ten percent in
interest of the capital stock entitled to vote at the meeting.

     C.   There shall be no cumulative voting by stockholders of any class or
series in the election of directors of the Corporation.


                                 ARTICLE VI(D)

                      NOTICE FOR NOMINATIONS AND PROPOSALS

     A.   Nominations for the election of directors and proposals for any new
business to be taken up at any annual or special meeting of stockholders may be
made by the Board of Directors of the Corporation or by any stockholder of the
Corporation entitled to vote generally in the election of directors.  In order
for a stockholder of the Corporation to make any such nominations and/or
proposals, he or she shall give notice thereof in writing, delivered or mailed
by first class United States mail, postage prepaid, to the Clerk of the
Corporation not less than 30 days nor more than 60 days prior to any such
meeting.  Each such notice given by a stockholder with respect to nominations
for the election of directors shall set forth (i) the name, age, business
address and, if known, residence address of each nominee proposed in such
notice, (ii) the principal occupation or employment of each such nominee, and
(iii) the number of shares of stock of the Corporation which are beneficially
owned by each such nominee.  In addition, the 

                                      -4-
<PAGE>
 
stockholder making such nomination shall promptly provide any other information
reasonably requested by the Corporation. Each such notice given by a stockholder
with respect to new business shall set forth as to each matter that the
stockholder proposes to bring before the meeting of stockholders (i) a brief
description of the proposal desired to be brought before the meeting and the
reasons for conducting such business at the meeting, (ii) the name and address,
as they appear on the Corporation's stock transfer books, of the stockholder
proposing such business and of the beneficial owners (if any) of the stock
registered in such stockholder's name and the name and address of other
stockholders known by such stockholder to be supporting the proposal, (iii) the
class and number of shares of the Corporation's capital stock which are held of
record, beneficially owned or represented by proxy by the stockholder and by any
other stockholders known by such stockholder to be supporting such proposal on
the record date for the meeting in question and on the date of such
stockholder's notice, and (iv) any material interest of the stockholder (or any
other stockholders known by such stockholders to be supporting such proposal) in
such proposal.

     B.   The presiding officer of the annual or special meeting of stockholders
may, if the facts warrant, determine and declare to such meeting that a
nomination or proposal was not made in accordance with the foregoing procedure,
and, if he should so determine, he shall so declare to the meeting and the
defective nomination or proposal shall be disregarded and laid over for action
at the next succeeding adjourned, special or annual meeting of the stockholders
taking place 30 days or more thereafter.  This provision shall not require the
holding of any adjourned or special meeting of stockholders for the purpose of
considering such defective nomination or proposal.


                                 ARTICLE VI(E)

                                   DIRECTORS

     A.   NUMBER; VACANCIES.  The number of directors of the Corporation shall
be such number, not less than 7 nor more than 18 as shall be provided from time
to time in or in accordance with the Bylaws, provided that no decrease in the
number of directors shall have the effect of shortening the term of any
incumbent director, and provided further that no action shall be taken to
decrease or increase the number of directors from time to time unless at least
two-thirds of the directors then in office shall concur in said action.
Vacancies in the Board of Directors of the Corporation, however caused, and
newly created directorships shall be filled solely by the affirmative vote of a
majority of the remaining directors then in office, whether or not a quorum, and
any director so chosen shall hold office for a term expiring at the annual
meeting of stockholders at which the term of the class to which the director has
been chosen expires and until the director's successor is elected and qualified.
Each director, when appointed or elected, shall take an oath that he will
faithfully perform the duties of his office and that he is the owner, in his own
right and free of any lien or encumbrance, of the required amount of stock as
set forth in the Bylaws of the Corporation.  The oath shall be taken before a
notary public or justice of the peace, who is not an officer of the Corporation,
and a record of the oath shall be made a part of the records of the Corporation.

     B.   CLASSIFIED BOARD.  The Board of Directors of the Corporation shall be
divided into three classes of directors as nearly equal in number as possible,
with one class to be elected annually.  The initial directors of the Corporation
shall hold office as follows:  the first class of directors shall hold office
initially for a term expiring at the annual meeting of stockholders to be held
in calendar 1998, the second class of directors shall hold office initially for
a term expiring at the annual of stockholders meeting to be held in calendar
1999, and the third class of directors shall hold office initially for a term
expiring at the annual meeting of stockholders to be held in calendar 2000, with
the members of each class to hold office until their respective successors are
duly elected and qualified.  At each annual meeting of stockholders of the
Corporation, the successors to the class of directors whose term expires at the
meeting shall be elected to hold office for a term expiring at the annual
meeting of stockholders held in the third year following the year of their
election and until their respective successors are elected and qualified.
Should the number of directors of the Corporation be increased, the additional
directorships shall be allocated among classes as appropriate so that the number
of directors in each class is as nearly equal as possible.

                                      -5-
<PAGE>
 
     Whenever the holders of any one or more series of preferred stock of the
Corporation shall have the right, voting separately as a class, to elect one or
more directors of the Corporation, the Board of Directors shall consist of said
directors so elected in addition to the number of directors fixed as provided
above in this Article VI(E).  Notwithstanding the foregoing, and except as
otherwise may be required by law, whenever the holders of any one or more series
of preferred stock of the Corporation shall have the right, voting separately as
a class, to elect one or more directors of the Corporation, the terms of the
director or directors elected by such holders shall expire at the next
succeeding annual meeting of stockholders.


                                 ARTICLE VI(F)

                              REMOVAL OF DIRECTORS

     Notwithstanding any other provision of these Articles or the Bylaws of the
Corporation, any director or the entire Board of Directors of the Corporation
may be removed at any time for cause only by the affirmative vote of the holders
of a majority of the outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors (considered for this
purpose as one class) cast at a meeting of the stockholders called for that
purpose.  For the purpose of this Article VI(F), "cause" shall mean (a) a
conviction of a felony by a court of competent jurisdiction, which conviction is
no longer subject to direct appeal, (b) a declaration of unsound mind by order
of court, (c) a gross dereliction of the director's duty to the Corporation, (d)
the commission by the director of an action involving moral turpitude, or (e)
the commission by the director of an action that constitutes intentional
misconduct or a knowing violation of law if such action in either event results
both in an improper substantial personal benefit and a material injury to the
Corporation.  In addition, any director or the entire Board of Directors of the
Corporation may be removed, at any time, without cause only by the affirmative
vote of the holders of at least two-thirds of the outstanding shares of capital
stock of the Corporation entitled to vote generally in the election of directors
(considered for this purpose as one class) cast at a meeting of stockholders
called for that purpose.  Notwithstanding the foregoing, whenever the holders of
any one or more series of preferred stock of the Corporation shall have the
right, voting separately as a class, to elect one or more directors of the
Corporation, the preceding provisions of this Article VI(F) respecting removal
by stockholders of the Corporation shall not apply with respect to the director
or directors elected by such holders of preferred stock.


                                 ARTICLE VI(G)

                            AFFILIATED TRANSACTIONS

     A.   VALIDITY. Except as otherwise provided in these Articles, if paragraph
B is satisfied, no contract or transaction between the Corporation and any of
its directors, officers or security holders, or any corporation, partnership,
association or other organization in which any of such directors, officers or
security holders are directly or indirectly financially interested, shall be
void or voidable solely because of this relationship, or solely because of the
presence of the director, officer or security holder at the meeting authorizing
the contract or transaction, or solely because of his or their participation in
the authorization of such contract or transaction or vote at the meeting
therefor, whether or not such participation or vote was necessary for the
authorization of such contract or transaction.

     B.   DISCLOSURE, APPROVAL; FAIRNESS. PARAGRAPH A SHALL APPLY ONLY IF:

     1. the material facts as to the relationship or interest and as to the
contract or transaction are disclosed or are known to the Board of Directors (or
a committee thereof) and it nevertheless in good faith authorizes or ratifies
the contract or transaction by a majority of the directors present, each such
interested director to be counted in determining whether a quorum is present but
not in calculating the majority necessary to carry the vote; and

                                      -6-
<PAGE>
 
     2. the contract or transaction is fair to the Corporation as of the time it
is authorized or ratified by the Board of Directors (or committee thereof) or
the stockholders.

                                 ARTICLE VI(H)

                                INDEMNIFICATION

     The Corporation shall indemnify each director or officer of the Corporation
to the fullest extent now or hereafter permitted by law against all expenses
(including attorneys' fees and disbursements), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative to which he is or is threatened to be
made a party by reason of the fact that he is or was a director, officer,
employee or agent of the Corporation or of a subsidiary of the Corporation, or
is or was a director, custodian, administrator, committeeman or fiduciary of any
employee benefit plan established and maintained by the Corporation or by a
subsidiary of the Corporation, or is or was serving another enterprise in any
such capacity at the written request of the Corporation.  To the extent
authorized at any time by the Board of Directors of the Corporation, the
Corporation may similarly indemnify other persons against liability incurred in
any capacity, or arising out of any status, of the character described in the
immediately preceding sentence.  At the discretion of the Board of Directors,
any indemnification hereunder may include payment by the Corporation of expenses
incurred in defending a civil or criminal action or proceeding in advance of the
final disposition of such action or proceeding, upon receipt of an undertaking
by the person indemnified to repay such payment if he shall be adjudicated to be
not entitled to indemnification under this Article VI(H) or applicable laws.  In
no event, however, shall the Corporation indemnify any director, officer, or
other person hereunder with respect to any matter as to which he shall have been
adjudicated in any proceeding not to have acted in good faith in the reasonable
belief that his action was in the best interests of the Corporation.  The
Corporation may purchase and maintain insurance to protect itself and any
present or former director, officer or other person against any liability of any
character asserted against and incurred by the Corporation or any such director,
officer or other person in any capacity, or arising out of any status, whether
or not the Corporation would have the power to indemnify such person against
such liability by law or under the provisions of this Article VI(H).  The
provisions of this Article VI(H) shall be applicable to persons who shall have
ceased to be directors or officers of the Corporation, and shall inure to the
benefit of the heirs, executors and administrators of persons entitled to
indemnity hereunder.  Nothing herein shall be deemed to limit the Corporation's
authority to indemnify any person pursuant to any contract or otherwise.


                                 ARTICLE VI(I)

                               ACTING AS PARTNER

     The Corporation may be a partner in any business enterprise which it would
have power to conduct by itself.


                                 ARTICLE VI(J)

                              AMENDMENT OF BYLAWS

     In furtherance and not in limitation of the powers conferred by statute,
the Board of Directors of the Corporation is expressly authorized to make,
repeal, alter, amend and rescind the Bylaws of the Corporation. Notwithstanding
any other provision of these Articles or the Bylaws of the Corporation (and
notwithstanding the fact that some lesser percentage may be specified by law),
the Bylaws shall not be made, repealed, altered, amended, or rescinded by the
stockholders of the Corporation except by the vote of the holders of not less
than two-thirds of the outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors (considered for this
purpose as one class) cast at a meeting of the stockholders called for that
purpose (provided that notice of such 

                                      -7-
<PAGE>
 
proposed adoption, repeal, alteration, amendment or rescission is included in
the notice of such meeting), or, as set forth above, by the Board of Directors
by the affirmative vote of not less than two-thirds of the directors then in
office.


                                 ARTICLE VI(K)

                     AMENDMENT OF ARTICLES OF ORGANIZATION

     The Corporation reserves the right to repeal, alter, amend or rescind any
provision contained in these Articles in the manner now or hereafter prescribed
by law, and all rights conferred on stockholders herein are granted subject to
this reservation.  Notwithstanding the foregoing, the provisions set forth in
Articles V, VI(C), VI(D), VI(E), VI(F), VI(H), VI(J) and this Article VI(K) of
these Articles may not be repealed, altered, amended, or rescinded in any
respect unless the same is approved by the affirmative vote of the holders of
not less than two-thirds of the outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors (considered
for this purpose as a single class) cast at a meeting of the stockholders called
for that purpose (provided that notice of such proposed adoption, repeal,
alteration, amendment or rescission is included in the notice of such meeting).
Any amendment, addition, alteration, change or repeal so acted upon shall be
effective on the date it is filed with the Secretary of State of the
Commonwealth of Massachusetts or on such other date as the Secretary of State
may specify.


                                 ARTICLE VI(L)

                   APPROVAL OF CERTAIN BUSINESS COMBINATIONS

     The stockholder vote required to approve Business Combinations (as
hereinafter defined) shall be as set forth in this Article V.  Such stockholder
vote shall be in addition to any affirmative vote required by the Massachusetts
General Laws.

     A.   (1) Except as otherwise expressly provided in this Article V, the
affirmative vote of the holders of at least two-thirds of the outstanding shares
entitled to vote thereon (and, if any class or series of shares is entitled to
vote thereon separately, the affirmative vote of the holders of at least two-
thirds of the outstanding shares of each such class or series) shall be required
in order to authorize any of the following:

          (a) any merger or consolidation of the Corporation with or into a
Related Person (as hereinafter defined);

          (b) any sale, lease, exchange, transfer or other disposition,

or of a subsidiary, to a Related Person;

          (c) any merger or consolidation of a Related Person with or into the
Corporation or a subsidiary of the Corporation;

          (d) any sale, lease, exchange, transfer or other disposition of all or
any Substantial Part of the assets of a Related Person to the Corporation or a
subsidiary of the Corporation;

          (e) the issuance of any securities of the Corporation or a subsidiary
of the Corporation to a Related Person;

          (f) the acquisition by the Corporation or a subsidiary of the
Corporation of any securities of a Related Person,

                                      -8-
<PAGE>
 
          (g) any reclassification of the common stock of the Corporation, or
any recapitalization involving the common stock of the Corporation, and

          (h) any agreement, contract or other arrangement providing for any of
the transactions described in this Article V.

     (2) Such affirmative vote shall be required notwithstanding any other
provisions of these Articles, any provision of law, or any agreement with any
regulatory agency, national securities exchange or registered securities
association which might otherwise permit a lesser vote or no vote.

     (3) The term "Business Combination" as used in this Article V shall mean
any transaction which is referred to in any one or more of subparagraphs 1(a)
through 1(h) above.

     B.  The provisions of Part A of this Article V shall not be applicable to
any particular Business Combination, and such Business Combination shall require
only such affirmative vote as is required by any other provision of these
Articles, any provision of law, or any agreement with any regulatory agency,
national securities exchange or registered securities association, if the
Business Combination shall have been approved by a majority of the Continuing
Directors (as hereinafter defined); provided, however, that such approval shall
only be effective if obtained at a meeting at which a Continuing Director Quorum
(as hereinafter defined) is present.

     C.  For the purposes of this section the following definitions apply:

          (1) The term "Related Person" shall mean and include (a) any
individual, corporation, partnership or other person or entity which together
with its "affiliates" (as that term is defined in Rule 12b-2 of the General
Rules and Regulations under the Securities Exchange Act of 1934), "beneficially
owns" (as that term is defined in Rule 13d-3 of the General Rules and
Regulations under the Securities Exchange Act of 1934) in the aggregate 10% or
more of the outstanding shares of the common stock of the Corporation; and (b)
any "affiliate" (as that term is defined in Rule 12b-2 under the Securities
Exchange Act of 1934) of any such individual, corporation, partnership or other
person or entity. Without limitation, any shares of the common stock of the
Corporation which any Related Person has the right to acquire pursuant to any
agreement, or upon exercise or conversion rights, warrants or options, or
otherwise, shall be deemed "beneficially owned" by such Related Person.

          (2) The term "Substantial Part" shall mean more than 25 percent of the
total assets of the Corporation, as of the end of its most recent fiscal year
ending prior to the time the determination is made.

          (3) The term "Continuing Director" shall mean any member of the Board
of Directors of the Corporation who is unaffiliated with the Related Person and
was a member of the Board prior to the time that the Related Person became a
Related Person, and any successor of a Continuing Director who is unaffiliated
with the Related Person and is recommended to succeed a Continuing Director by a
majority of Continuing Directors then on the Board.

          (4) The term "Continuing Director Quorum" shall mean two-thirds of the

                                   ARTICLE I

     The main office of Sandwich Bancorp, Inc. (the "Corporation") shall be in
the Town of Sandwich, Massachusetts, or such other location as the Board of
Directors may designate, subject to applicable law.


                                  ARTICLE II

                                 STOCKHOLDERS

     SECTION 1.  ANNUAL MEETING.  The Annual Meeting of the stockholders for
elections and other purposes shall be held within six months after the end of
the Corporation's fiscal year at such date, time and place as fixed by the Board
of Directors, the Chairman of the Board or the President, consistent with the
requirements of Massachusetts law.  The purposes for which the Annual Meeting is
to be held, in addition to those prescribed by law, by the Articles of
Organization or by these Bylaws, may be specified by the Board of Directors, the
Chairman of the Board or the President.

     SECTION 2.  SPECIAL MEETINGS.  Special meetings of the stockholders may be
called only as provided in the Corporation's Articles of Organization.

     SECTION 3.  NOTICE OF MEETINGS.  A written notice of all annual and special
meetings of stockholders stating the place, date and hour and the purpose or
purposes of such meeting shall be given by the Clerk or an assistant clerk (or
other person authorized by these Bylaws) at least seven days before the meeting
to each stockholder entitled to vote thereat and to each stockholder who, by
law, under the Articles of Organization or under these Bylaws, is entitled to
such notice, by delivering such notice to him or by mailing it, postage prepaid,
and addressed to such stockholder at his address as it appears on the stock
transfer books of the Corporation.  Such notice shall be deemed to be delivered
when hand delivered to such address or deposited in the mail so addressed, with
postage prepaid.

     When any stockholders' meeting, either annual or special, is adjourned for
30 days or more, notice of the adjourned meeting shall be given as in the case
of an original meeting.  It shall not be necessary to give any notice of the
time and place of any meeting adjourned for less than 30 days or of the business
to be transacted thereat, other than an announcement at the meeting at which
such adjournment is taken.

     SECTION 4.  QUORUM.  The holders of a majority in interest of all stock
issued, outstanding, and entitled to vote, represented in person or by proxy,
shall constitute a quorum at a meeting of stockholders.  If a quorum is not
present, a lesser number may adjourn the meeting from time to time and the
meeting may be held as adjourned without further notice.  At such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the meeting as originally
noticed.  The stockholders present at a duly organized meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

                                      -1-
<PAGE>
 
     SECTION 5.  VOTING AND PROXIES.  Stockholders shall have one vote for each
share of stock entitled to vote owned by them of record according to the books
of the Corporation, and a proportionate vote for a fractional share, unless
otherwise provided by law or by the Articles of Organization.  Stockholders may
vote either in person or by written proxy dated not more than six months before
the meeting named therein.  Proxies shall be filed with the clerk of the
meeting, or of any adjournment thereof, before being voted.  Except as otherwise
limited therein, proxies shall entitle the persons authorized thereby to vote at
any adjournment of such meeting, but they shall not be valid after final
adjournment of such meeting.  A proxy with respect to stock held in the name of
two or more persons shall be valid if executed by one of them unless at or prior
to exercise of the proxy the Corporation receives a specific written notice to
the contrary from any one of them.  A proxy purporting to be executed by or on
behalf of a stockholder shall be deemed valid unless challenged at or prior to
its exercise, and the burden of proving invalidity shall rest on the challenger.

     SECTION 6.  ACTION AT MEETING.  When a quorum is present, any matter before
the meeting shall be decided by vote of the holders of a majority of the shares
of stock voting on such matter, except where a larger vote is required by law,
by the Articles of Organization or by these Bylaws.  Any election by
stockholders shall be determined by a plurality of the votes cast, except where
a larger vote is required by law, by the Articles of Organization or by these
Bylaws.  No action may be taken on the nomination of a director unless the
procedures set forth in the Articles of Organization have been complied with.
No ballot shall be required for any election unless requested by a stockholder
entitled to vote in the election.  The Corporation shall not directly or
indirectly vote any share of its own stock; provided however, that no provision
of these Bylaws shall be construed to limit the voting rights and powers
relating to shares of stock held pursuant to a plan which is intended to be an
"employee stock ownership plan" as defined in section 409A of the Internal
Revenue Code, as now or hereafter in effect.


                                  ARTICLE III

                                   DIRECTORS

     SECTION 1.  POWERS. The business and affairs of the Corporation shall be
managed by a Board of Directors who may exercise all the powers of the
Corporation except as otherwise provided by law, by the Articles of Organization
or by these Bylaws.

     SECTION 2.  NUMBER, TERM AND ELECTION.  The Board of Directors shall
initially consist of 13 members and shall be divided into three classes as
nearly equal in number as possible, with one class to be elected annually.  The
Board of Directors shall be classified in accordance with the provisions of the
Corporation's Articles of Organization. At each annual meeting of stockholders,
the successors to the directors of the class whose term shall expire in that
year shall be elected to hold office for a term expiring at the annual meeting
of stockholders held in the third year following the year of their election and
until their respective successors are elected and qualified.  The Board of
Directors may increase or decrease the number of members of the Board of
Directors by a vote of at least two-thirds of the board members then in office,
provided the total number of directors on the board may not be more than 18 nor
less than 7.

     SECTION 3.  QUALIFICATION.  Each director shall have such qualifications as
are required by applicable law.  In addition, all directors shall be citizens of
the United States of America and residents therein.  Each director shall own,
free of any lien or encumbrance, in his own right or through a company in which
he holds an ownership interest of at least seventy-five percent, common stock of
the Corporation, having a par value, or a fair market value on the date the
person became a director, of not less than one thousand dollars.  Any director
who ceases to be the owner of the required number of shares of stock, or who
becomes in any other manner disqualified, shall vacate his office forthwith.  No
person shall be eligible for election or reelection to the Board if he shall
have attained 72 years of age.

     SECTION 4.  REGULAR MEETINGS.  A regular meeting of the Board of Directors
shall be held without other notice than this Bylaw at the same place as the
annual meeting of stockholders, or the special meeting held in lieu thereof,

                                      -2-
<PAGE>
 
following such meeting of stockholders.  The Board of Directors may provide, by
resolution, the time and place for the holding of regular meetings without other
notice than such resolution.

     SECTION 5.  SPECIAL MEETINGS.  Special meetings of the Board of Directors
may be called by or at the request of the Chairman of the Board, the President,
or a majority of the directors.  The persons authorized to call special meetings
of the Board of Directors may fix the place for holding any special meeting of
the Board of Directors called by such persons.

     SECTION 6.  NOTICE. Notice of any special meeting shall be given to each
director in person or by telephone or sent to his business or home address by
telegram at least 24 hours in advance of the meeting or by written notice mailed
to his business or home address at least 48 hours in advance of such meeting.
Such notice shall be deemed to be delivered when deposited in the mail so
addressed, with postage thereon prepared if mailed, or when delivered to the
telegraph company if sent by telegram.  Any director may waive notice of any
meeting by a writing filed with the records of the meeting.  The attendance of a
director at a meeting shall constitute a waiver of notice of such meeting,
except where a director attends a meeting for the express purpose of objecting
to the transaction of any business because the meeting is not lawfully called or
converted.  Neither the business to be transacted at, nor the purpose of, any
meeting of the Board of Directors need be specified in the notice or waiver of
notice of such meeting.

     SECTION 7.  QUORUM.  A majority of the number of directors then in office
shall constitute a quorum for the transaction of business at any meeting of the
Board of Directors, but if less than such majority is present at a meeting, a
majority of the directors present may adjourn the meeting from time to time.
When any Board of Directors' meeting either regular or special is adjourned for
30 days or more, notice of the adjourned meeting shall be given as in the case
of an original meeting.  It shall not be necessary to give any notice of the
time and place of any meeting adjourned for less than 30 days or of the business
to be transacted thereat, other than an announcement at the meeting at which
such adjournment is taken.

     SECTION 8.  MANNER OF ACTING.  The act of the majority of the directors
present at a meeting at which a quorum is present shall be the act of the Board
of Directors, unless a greater number is prescribed by governing law, by the
Articles of Organization or these Bylaws.

     SECTION 9.  ACTION BY CONSENT.  Any action required or permitted to be
taken by the Board of Directors at a meeting may be taken without a meeting if a
consent in writing, setting forth the action so taken, shall be signed by all of
the directors and such consents are filed with the records of the meetings of
directors.

     SECTION 10.  RESIGNATION.  Any director may resign at any time by sending a
written notice of such resignation to the main office of the Corporation
addressed to the Chairman of the Board or the President.  Unless otherwise
specified therein, such resignation shall take effect upon receipt thereof by
the Chairman of the Board or the President.

     SECTION 11.  REMOVALS.  A director may be removed from office only as
provided in the Articles of Organization.

     SECTION 12.  VACANCIES.  Any vacancy occurring on the Board of Directors as
a result of resignation, removal or death may be filled in accordance with the
provisions of the Articles of Organization.

     SECTION 13.  COMPENSATION.  The members of the Board of Directors and the
members of either standing or special committees may be allowed such
compensation as the Board of Directors may determine.

     SECTION 14.  PRESUMPTION OF ASSENT.  A director of the Corporation who is
present at a meeting of the Board of Directors at which action on any
Corporation matter is taken shall be presumed to have assented to the action
taken unless his or her dissent or abstention shall be entered in the minutes of
the meeting or unless he or she shall file a written dissent to such action with
the person acting as the clerk of the meeting before the adjournment thereof or
shall 

                                      -3-
<PAGE>
 
forward such dissent by registered mail to the Clerk of the Corporation within
five days after the date a copy of the minutes of the meeting is received. Such
right to dissent shall not apply to a director who voted in favor of such
action.

     SECTION 15.  COMMITTEES.  The Board of Directors, by a vote of a majority
of the directors then in office, may elect from its number, not less than three
members in each case to serve as an Executive Committee or other committees and
may delegate thereto some or all of its powers except those which by law, by the
Articles of Organization, or by these Bylaws may not be delegated.  Except as
the Board of Directors may otherwise determine, any such committee may make
rules for the conduct of its business, but unless otherwise provided by the
Board of Directors or in such rules, its business shall be conducted so far as
possible in the same manner as is provided by these Bylaws for the Board of
Directors.  All members of such committees shall hold such offices at the
pleasure of the Board of Directors. The Board of Directors may abolish any such
committee at any time, subject to any applicable requirements of law.  Any
committee to which the Board of Directors delegates any of its powers or duties
shall keep records of its meetings and shall report its action to the Board of
Directors.  The Board of Directors shall have power to rescind any action of any
committee, but no such rescission shall have retroactive effect.  In the case of
the Nominating Committee, which shall be established for the purpose of making
nominations for election to the Board of Directors, such committee shall consist
of at least five members, including the president.  The committee shall deliver
its nominations to the secretary of the Corporation at least 30 days in advance
of the meeting at which elections are to be held.

     SECTION 16.  MANNER OF PARTICIPATION.  Members of the Board of Directors
may participate in meetings of the Board of Directors by means of conference
telephone or similar communications equipment by which all persons participating
in the meeting can hear each other.  Such participation shall constitute
presence in person but shall not constitute attendance for the purpose of
compensation pursuant to Section 13 of this Article III, unless the Board of
Directors by resolution so provides.


                                  ARTICLE IV

                                   OFFICERS

     SECTION 1.  ENUMERATION.  The officers of the Corporation shall consist of
a President, a Treasurer, a Clerk, and such other officers, including Chairman,
Vice Chairmen of the Board, Vice Presidents or Assistant Vice Presidents,
Assistant Treasurers, Assistant Clerks or a Secretary or Assistant Secretaries,
as the Board of Directors may determine.

     SECTION 2.  ELECTION.  The President, Treasurer and Clerk shall be elected
annually by the Board of Directors at their first meeting following the annual
meeting of stockholders.  The President shall be a director of the Corporation.
Other officers may be chosen by the Board of Directors at such first meeting of
the Board of Directors or at any other meeting.

     SECTION 3.  QUALIFICATION.  No officer need be a stockholder.  Any two or
more offices may be held by any person.  The Clerk shall be a resident of
Massachusetts unless the Corporation has a resident agent appointed for the
purpose of service of process.  Any officer may be required by the Board of
Directors to give bond for the faithful performance of his duties in such amount
and with such sureties as the Board of Directors may determine.

     SECTION 4.  TENURE.  Except as otherwise provided by law, by the Articles
of Organization or by these Bylaws, all officers shall hold office until the
first meeting of the Board of Directors following the next annual meeting of
stockholders and until their respective successors are chosen and qualified.
Any officer may resign by delivering his written resignation to the Corporation
at its main office addressed to the Chairman of the Board, the President, Clerk
or Secretary, and such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.  Election or appointment of an officer, employee or agent shall not of
itself create contract rights.  The Board of Directors may authorize the
Corporation to enter into an employment contract with any officer in accordance
with governing law or regulation, but no such contract right shall impair the
right of the Board of Directors to remove any officer at any time in accordance

     SECTION 1.  CERTIFICATES OF STOCK.  Each stockholder shall be entitled to a
certificate of the capital stock of the Corporation in such form as may from

transfer agent, or by a registrar, other than a director, officer or employee of
the Corporation.  In case any officer who has signed or whose facsimile
signature has been placed on such certificate shall have ceased to be such
officer before such certificate is issued, it may be issued by the Corporation
with the same effect as if he were such officer at the time of its issue.

     SECTION 2.  TRANSFERS.  Subject to any restrictions on transfer, shares of
stock may be transferred on the books of the Corporation by the surrender to the
Corporation or its transfer agent of the certificate therefor properly endorsed

postal address.

     SECTION 4.  RECORD DATE.  The Board of Directors may fix in advance a time
of not more than 60 days preceding the date of any meeting of stockholders, or
the date for the payment of any dividend or the making of any distribution to

may be effectively expressed for any purpose, as the record date for determining
the stockholders having the right to notice of and to vote at such meeting, or

consent or dissent. In such case only stockholders of record on such record date
shall have such right, notwithstanding any transfer of stock on the books of the
Corporation after the record date.  Without fixing such record date the Board of
Directors may for any of such purposes close the transfer books for all or any
part of such period.

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS AGREEMENT entered into this 18th day of July, 1994, by and between The
Sandwich Co-operative Bank (the "Bank") and Frederic D. Legate (the "Employee"),
and hereby replaces the Employment Agreement between the Bank and the Employee,
as first dated July 17, 1989 (as amended).

     WHEREAS, the Employee has heretofore been employed by the Bank as President
and Chief Executive Officer and is experienced in all phases of the business of
the Bank; and

     WHEREAS, the parties desire by this writing to set forth the continuing
employment relationship of the Bank and the Employee.

     NOW, THEREFORE, it is AGREED as follows:

     1.   Employment.  The Employee is employed as the President and Chief
          ----------                                                      
Executive officer of the Bank.  The Employee shall render such administrative
and management services for the Bank as are currently rendered and as are
customarily performed by persons situated in a similar executive capacity.  The
Employee shall also promote, by entertainment or otherwise, as and to the extent
permitted by law, the business of the Bank.  The Employee's other duties shall
be such as the Board of Directors of the Bank ("Board") may from time to time
reasonably direct, including normal duties as an officer of the Bank.

     2.   Base Compensation.  The Bank agrees to pay the Employee during the
          -----------------                                                 
term of this Agreement a salary at the rate of $185,000 per annum, payable in
cash not less frequently than monthly.  The Board shall review, not less often
than annually, the rate of the Employee's salary, and in its sole discretion may
decide to increase his salary.

     3.   Discretionary Bonuses.  The Employee shall participate in an equitable
          ---------------------                                                 
manner with all other senior management employees of the Bank in discretionary
bonuses that the Board may award from time to time to the Bank's senior
management employees.  No other compensation provided for in this Agreement
shall be deemed a substitute for the Employee's right to participate in such
discretionary bonuses.

     4.   (a) Participation in Retirement, Medical and Other Plans.
              ---------------------------------------------------- 

The Employee shall participate in any plan that the Bank maintains for the
benefit of its employees if the plan relates to (i) pension, profit-sharing, or
other retirement benefits, (ii) medical insurance or the reimbursement of
medical or dependent care expenses, or (iii) other group benefits, including
disability and life insurance plans.

          (b) Employee Benefits, Expenses.  The Employee shall participate in
              ---------------------------

<PAGE>
 
available to the Bank's senior management employees, including for example: any
stock option or incentive compensation plans, club memberships, and any other
benefits which are commensurate with the responsibilities and functions to be
performed by the Employee under this Agreement. The Employee shall be reimbursed
for all reasonable out-of-pocket business expenses which he shall incur in
connection with his services under this Agreement upon substantiation of such
expenses in accordance with the policies of the Bank.

     5.   Term.  The Bank hereby employs the Employee, and the Employee hereby
          ----                                                                
accepts such employment under this Agreement, for the period commencing on July
18, 1994 and ending 36 months thereafter on July 17, 1997 (or such earlier date
as is determined in accordance with Section 9) ; provided that notwithstanding
any determination by the Bank not to extend the term of this Agreement I said
term shall not expire prior to the expiration of thirty-six (36) months after a
Change in Control (as defined in Section 11) shall have occurred.  Additionally,
on each annual anniversary date from the Effective Date, the Employee's term of
employment shall be extended for an additional one-year period beyond the then
effective expiration date provided the Board determines in a duly adopted
resolution that the performance of the Employee has met the Board's requirements
and standards, and that this Agreement shall be extended.

     6.   Loyalty; Noncompetition.
          ----------------------- 

          (a) During the period of his employment hereunder and except for
illnesses, reasonable vacation periods, and reasonable leaves of absence, the
Employee shall devote all his full business time, attention, skill, and efforts
to the faithful performance of his duties hereunder; provided, however, from
time to time, Employee may serve on the boards of directors of, and hold any
other offices or positions in, companies or organizations, which will not
present any conflict of interest with the Bank or any of its subsidiaries or
affiliates, or unfavorably affect the performance of Employee's duties pursuant
to this Agreement, or will not violate any applicable statute or regulation.
"Full business time" is hereby defined as that amount of time usually devoted to
like companies by similarly situated executive officers. During the term of his
employment under this Agreement, the Employee shall not engage in any business
or activity contrary to the business affairs or interests of the Bank, or be
gainfully employed in any other position or job other than as provided above.

          (b) Nothing contained in this Paragraph 6 shall be deemed to prevent
or limit the Employee's right to invest in the capital stock or other securities
of any business dissimilar from that of the Bank, or, solely as a passive or
minority investor, in any business.

                                      -2-

     7.   Standards.  The Employee shall perform his duties under this Agreement
          ---------                                                             
in accordance with such reasonable standards as the Board may establish from
time to time. The Bank will provide Employee with the working facilities and
staff customary for similar executives and necessary for him to perform his
duties.

     8.   Vacation and Sick Leave.  At such reasonable times as the Board shall
          -----------------------                                              
in its discretion permit, the Employee shall be entitled, without loss of pay,
to absent himself voluntarily from the performance of his employment under this
Agreement, all such voluntary absences to count as vacation time; provided that:

          (a) The Employee shall be entitled to an annual vacation in accordance
with the policies that the Board periodically establishes for senior management
employees of the Bank.

          (b) The Employee shall not receive any additional compensation from
the Bank on account of his failure to take a vacation or sick leave, and the
Employee shall not accumulate unused vacation or sick leave from one fiscal year
to the next, except in either case to the extent authorized by the Board.

          (c) In addition to the aforesaid paid vacations, the Employee shall be
entitled without loss of pay, to absent himself voluntarily from the performance
of his employment with the Bank for such additional periods of time and -for
such valid and legitimate reasons as the Board may in its discretion determine.
Further, the Board may grant to the Employee a leave or leaves of absence, with
or without pay, at such time or times and upon such terms and conditions as such
Board in its discretion may determine.

          (d) In addition, the Employee shall be entitled to an annual sick
leave benefit as established by the Board.

     9.   Termination and Termination Pay.  Subject to Section 11 hereof, the
          -------------------------------                                    
Employee Is employment hereunder may be terminated under the following
circumstances:

          (a) Death. The Employee's employment under this Agreement shall
              -----                                                      
terminate upon his death during the term of this Agreement, in which event the
Employee's estate shall be entitled to receive the compensation due the Employee
through the last day of the calendar month in which his death occurred.

          (b) Disability.  If the Employee shall become disabled or
              ----------                                           
incapacitated to the extent that he is unable to perform his duties hereunder,
by reason of a medically determinable physical or mental impairment, as
determined by a doctor engaged by the Board of Directors, Employee shall
nevertheless continue to receive the following percentages of his compensation,
inclusive of any benefits which may be payable to Employee under the provisions
of disability insurance coverage in effect for Bank employees, under

                                      -3-
<PAGE>
 
Paragraph 2 of this Agreement for the following periods of his disability: 60%
for the remaining term of this Agreement. Upon returning to active full-time
employment, the Employee's full compensation as set forth in this Agreement
shall be reinstated. In the event that said Employee returns to active
employment on other than a full-time basis, then his compensation (as set forth
in Paragraph 2 of this Agreement) shall be reduced in proportion to the time
spent in said employment, or as shall otherwise be agreed to by the parties.

          (c) Just Cause.  The Board may, by written notice to the Employee,
              ----------                                                    
immediately terminate his employment at any time, for Just Cause.  The Employee
shall have no right to receive compensation or other benefits for any period
after termination for Just Cause.  Termination for "Just Cause" shall mean
termination because of, in the good faith determination of the Board, the
Employee's personal dishonesty, incompetence, willful misconduct, breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule or regulation (other than traffic
violations or similar offenses) or final cease-and-desist order, or material
breach of any provision of this Agreement.  No act, or failure to art, on the
Employee's part shall be considered "willful" unless he has acted, or failed to
act, with an absence of good faith and without a reasonable belief that his
action or failure to act was in the best interest of the Bank.  Notwithstanding
the foregoing, (i) the Employee shall not be deemed to have been terminated for
Just Cause unless there shall have been delivered to the Employee a copy of a
resolution duly adopted by the affirmative vote of not less than a majority of
the entire membership of the Board at a meeting of the Board called and held for
that purpose (after reasonable notice to the Employee and an opportunity for the
Employee to be heard before the Board), finding that in the good faith opinion
of the Board the Employee was guilty of conduct set forth above in the third
sentence of this Subsection (c) and specifying the particulars thereof in
detail.

          (d) Without Just Cause.  Subject to Section 11 hereof, the Board may,
              ------------------                                               
by written notice to the Employee, immediately terminate his employment at any
time for a reason other than Just Cause, in which event the Employee shall be
entitled to receive the following compensation and benefits: (I) the salary
provided pursuant to Section 2 hereof,, up to the date of termination of the
term (including any renewal term) of this Agreement (the "Expiration Date"),
plus said salary for an additional 12-month period, but in no event in excess of
three years' salary and (ii) the cost to the Employee of obtaining all health,
life, disability and other benefits which the Employee would have been eligible
to participate in through the Expiration Date based upon the benefit levels
substantially equal to those that the Bank provided for the Employee at the date
of termination of employment.  Said sum shall be paid, at the option of the
Employee, either (I) in periodic payments over the remaining term of this
Agreement, as if the

                                      -4-
<PAGE>
 
Employee's employment had not been terminated, or (II) in one lump sum within
ten (10) days of such termination.

          (e) Termination or Suspension Under Federal Law. (1) If the Employee
              -------------------------------------------                     
is removed and/or permanently prohibited from participating in the conduct of
the Bank's affairs by an order issued under Sections 8 (e) (4) or 8 (g) (1) of
the Federal Deposit Insurance Act ("FDIC") (12 U.S.C. 1818(e) (4) and (g) (1)),
all obligations of the Bank under this Agreement shall terminate, as of the
effective date of the order, but vested rights of the parties shall not be
affected.

          (2) If the Bank is in default (as defined in Section 3 (x) (1) of
FDIA), all obligations under this Agreement shall terminate as of the date of
default; however, this Paragraph shall not affect the vested rights of the
parties.

          (3) All obligations under this Agreement shall terminate, except to
the extent that continuation of this Agreement is necessary for the continued
operation of the Bank: (I) by the Commissioner of Banks of the Commonwealth of
Massachusetts (the "Commissioner") or his or her designee, at the time that the
Federal Deposit Insurance Corporation ("FDIC") enters into an agreement to
provide assistance to or on behalf of the Bank under the authority contained in
Section 13(c) of FDIA; or (ii) by the commissioner, or his or her designee, at
the time that the Commissioner, or his or her designee approves a supervisory
merger to resolve problems related to operation of the Bank or when the Bank is
determined by the Commissioner to be in an unsafe or unsound condition. Such
action shall not affect any vested rights of the parties.

          (4) If a notice served under Section 8 (e) (3) or (g) (1) of the FDIA
(12 U.S.C. 1818(e)(3) or (g)(1)) suspends and/or temporarily prohibits the
Employee from participating in the conduct of the Bank's affairs, the Bank's
obligations under this Agreement shall be suspended as of the date of such
service, unless stayed by appropriate proceedings. If the charges in the notice
are dismissed, the Bank shall (I) pay the Employee all or part of the
compensation withhold while its contract obligations were suspended, and (ii)
reinstate (in whole or -in part) any of its obligations which were suspended.

          (f) Voluntary Termination by Employee.  Subject to Section 11 hereof,
              ---------------------------------                                
the Employee may voluntarily terminate employment with the Bank during the term
of this Agreement, upon at least 60 days' prior written notice to the Board of
Directors, in which case the Employee shall receive only his compensation,
vested rights and employee benefits up to the date of his termination.

     10.  No Mitigation.  The Employee shall not be required to mitigate the
          -------------                                                     
amount of any payment provided for in this Agreement

                                      -5-
<PAGE>
 
by seeking other employment or otherwise and no such payment shall be offset or
reduced by the amount of any compensation or benefits provided to the Employee
in any subsequent employment.

     11.  Change in Control.
          ----------------- 

          (a) Notwithstanding any provision herein to the contrary, if the
Employee's employment under this Agreement is terminated by the Bank, without
the Employee's prior written consent and for a reason other than Just Cause, in
connection with or within twelve (12) months after any change in control of the
Bank, the Employee shall be paid an amount equal to the difference between (I)
the product of 2.99 times his "base amount" as defined in Section 28OG(b) (3) of
the Internal Revenue Code of 1986, as amended (the "Code") and regulations
promulgated thereunder, and (ii) the sum of any other parachute payments (as
defined under Section 28OG(b) (2) of the Code) that the Employee receives on
account of the change in control.  Said sum shall be paid in one lump sum within
ten (10) days of such termination.

     The term "change in control" shall mean (1) the ownership, holding or power
to vote more than 25% of the Bank's voting stock-, (2) the control of the
election of a majority of the Bank's directors, (3) the exercise of a
controlling influence over the management or policies of the Bank by any person
or by persons acting as a "group" (within the meaning of Section 13(d) of the
Securities Exchange Act of 1934), or (4) during any period of two consecutive
years, individuals (the "Continuing Directors") who at the beginning of such
period constitute the Board of Directors of the Bank (the "Incumbent Board")
cease for any reason to constitute at least two-thirds thereof, provided that
any individual whose election or nomination for election as a member of the
Incumbent Board was approved by a vote of at least two-thirds of the Continuing
Directors then in office shall be considered a Continuing Director.  The term
"person" means an individual other than the Employee, or a corporation,
partnership, trust, association, joint venture, pool, syndicate, sole
proprietorship, unincorporated organization or any other form of entity not
specifically listed herein.

          (b) Notwithstanding any other provision of this Agreement to the
contrary, the Employee may voluntarily terminate his employment under this
Agreement within twelve (12) months following a change in control of the Bank,
and the Employee shall thereupon be entitled to receive the payment described in
Section 11(a) of this Agreement, upon the occurrence of any of the following
events, or within ninety (90) days thereafter, which have not been consented to
in advance by the Employee in writing: (i) the requirement that the Employee
move his personal residence, or perform his principal executive functions, more
than thirty-five (35) miles from Sandwich, Massachusetts; (ii) a material
reduction in the Employee's base compensation as in effect on the date of the

                                      -6-
<PAGE>
 
change in control or as the same may be increased from time to time; (iii) the
failure by the Bank to continue to provide the Employee with compensation and
benefits provided for under this Agreement, as the same may be increased from
time to time, or with benefits substantially similar to those provided to him
under any of the employee benefit plans in which the Employee now or hereafter
becomes a participant, or the taking of any action by the Bank which would
directly or indirectly reduce any of such benefits or deprive the Employee of
any material fringe benefit enjoyed by him at the time of the change in control;
(iv) the assignment to the Employee of duties and responsibilities materially
different from those normally associated with his position as referenced at
Section 1; (v) a failure to elect or reelect the Employee to the Board of
Directors of the Bank, if the Employee is serving on the Board on the date of
the change in control; or (vi) a material diminution or reduction in the
Employee's responsibilities or authority (including reporting responsibilities)
in connection with his employment with the Bank.

          (c) Any payments made to the Employee pursuant to this Agreement, or
otherwise, are subject to and conditioned upon their compliance with 12 U.S.C.
Section 1828(k) and any regulations promulgated thereunder.

          (d) Within five business days before or after a change in control as
defined in 511(a) of this Agreement, the Bank shall (I) deposit, or cause to be
deposited, in trust (the "Trust) an amount equal to 2.99 times the Employee's
"base amount" as defined in Section 28OG(b) (3) of the Code, and (ii) provide
the trustee of the Trust with a written direction to hold said amount and any
investment return thereon in a segregated account for the benefit of the
Employee, and to follow the procedures set forth in the next paragraph as to the
payment of such amounts from the Trust.

          During the 12-consecutive month period following the date on which the
Bank makes the deposit referred to in the preceding paragraph, the Employee may
provide the trustee of the Trust with a written notice requesting that the
trustee pay to the Employee an amount designated in the notice as being payable
pursuant to Section 11 (a) or (b).   Within three business days after receiving
said notice, the trustee of the Trust shall send a copy of the notice to the
Bank via overnight and registered mail return receipt requested.  On the tenth
(10th) business day after mailing said notice to the Bank, the trustee of the
Trust shall pay the Employee the amount designated therein in immediately
available funds, unless prior thereto the Bank provides the trustee with a
written notice directing the trustee to withhold such payment.   In the latter
event, the trustee shall submit the dispute to nonappealable binding arbitration
for a determination of the amount payable to the Employee pursuant to Section 11
(a) or (b) hereof, and the costs of such arbitration (including any legal fees
and expenses incurred by the Employee) shall be paid by the Bank.

                                      -7-
<PAGE>
 
The trustee shall choose the arbitrator to settle the dispute, and such
arbitrator shall be bound by the rules of the American Arbitration Association
in making his determination.  The parties and the trustee shall be bound by the
results of the arbitration and, within 3 days of the determination by the
arbitrator, the trustee shall pay from the Trust the amounts required to be paid
to the Employee and/or the Bank, and in no event shall the trustee be liable to
either party for making the payments as determined by the arbitrator.

          Upon the earlier of (I) any payment from the Trust to the Employee, or
(ii) the date 12 months after the date on which the Bank makes the deposit
referred to in the first paragraph of this subsection (d), the trustee of the
Trust shall pay to the Bank the entire balance remaining in the segregated
account maintained for the benefit of the Employee.  The Employee shall
thereafter have no further rights under this Section 11, no further interest in
the Trust pursuant to this Agreement, and no further rights or claims against
the Bank pursuant to this Agreement.

          (e) In the event that any dispute arises between the Employee and the
Bank as to the terms or interpretation of this Agreement, including this Section
11, whether instituted by formal legal proceedings or otherwise, including any
action that the Employee takes to enforce the terms of this Section 11 or to
defend against any action taken by the Bank, the Employee shall be reimbursed
for all costs and expenses, including reasonable attorneys' fees, arising from
such dispute, proceedings or actions, provided that the Employee shall obtain a
final judgement by a court of competent jurisdiction in favor of the Employee.
Such reimbursement shall be paid within ten (10) days of Employee's furnishing
to the Bank written evidence, which may be in the form, among other things, of a
canceled check or receipt, of any costs or expenses incurred by the Employee.

     12.  Successors and Assigns.
          ---------------------- 

          (a) This Agreement shall inure to the benefit of and be binding upon
any corporate or other successor of the Bank which shall acquire, directly or
indirectly, by merger, consolidation, purchase or otherwise, all or
substantially all of the assets or stock of tho Bank.

          (b) Since the Bank is contracting for the unique and personal skills
of the Employee, the Employee shall be precluded from assigning or delegating
his rights or duties hereunder without first obtaining the written consent of
the Bank.

     13.  Amendments.  No amendments or additions to this Agreement shall be
          ----------

respects, whether as to its validity, construction, capacity, performance or

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS AGREEMENT entered into this 18th day of July, 1994, by and between The
Sandwich Co-operative Bank (the "Bank") and Dana S. Briggs (the "Employee"), and
hereby replaces the Employment Agreement between the Bank and the Employee, as
first dated July 17, 1989 (as amended).

     WHEREAS, the Employee has heretofore been employed by the Bank as Senior
Vice President and Administration Officer and is experienced in all phases of
the business of the Bank; and

     WHEREAS, the parties desire by this writing to set forth the
continuing employment relationship of the Bank and the Employee.

     NOW, THEREFORE, it is AGREED as follows:

     1.   Employment.  The Employee is employed as the Senior Vice President and
          ----------                                                            
Administration Officer of the Bank.  The Employee shall render such
administrative and management services for the Bank as are currently rendered
and as are customarily performed by persons situated in a similar executive
capacity.  The Employee shall also promote, by entertainment or otherwise, as
and to the extent permitted by law, the business of the Bank.  The Employee's
other duties shall be such as the Board of Directors of the Bank ("Board") may
from time to time reasonably direct, including normal duties as an officer of
the Bank.

     2.   Base Compensation.  The Bank agrees to pay the Employee during the
          -----------------                                                 
term of this Agreement a salary at the rate of $76,000 per annum, payable in
cash not less frequently than monthly.  The Board shall review, not less often
than annually, the rate of the Employee's salary, and in its sole discretion may
decide to increase his salary.

     3.   Discretionary Bonuses.  The Employee shall participate in an equitable
          ---------------------                                                 
manner with all other senior management employees of the Bank in discretionary
bonuses that the Board may award from time to time to the Bank's senior
management employees.  No other compensation provided for in this Agreement
shall be deemed a substitute for the Employee's right to participate in such
discretionary bonuses.

     4.   (a) Participation in Retirement, Medical and Other Pl=.
              -------------------------------------------------- 

The  Employee shall participate in any plan that the Bank maintains for  the
benefit of its employees if the plan relates to (i) pension, profit-sharing, or
other retirement benefits, (ii) medical insurance or the reimbursement of
medical or dependent care expenses, or (iii) other group benefits, including
disability and life insurance plans.

          (b) Employee Benefits: Expenses.  The Employee shall participate  in
              --------------------------- 
any  fringe  benefits  which  are  or  may  become
<PAGE>
 
available to the Bank's senior management employees, including for example: any
stock option or incentive compensation plans, club memberships, and any other
benefits which are commensurate with the responsibilities and functions to be
performed by the Employee under this Agreement.  The Employee shall be
reimbursed for all reasonable out-of-pocket business expenses which he shall
incur in connection with his services under this Agreement upon substantiation
of such expenses in accordance with the policies of the Bank.

     5.   Term.  The Bank hereby employs the Employee, and the Employee hereby
          ----                                                                
accepts such employment under this Agreement, for the period commencing on July
18, 1994 and ending 36 months thereafter on July 17, 1997 (or such earlier date
as is determined in accordance with Section 9); provided that notwithstanding
any determination by the Bank not to extend the term of this Agreement, said
term shall not expire prior to the expiration of thirty-six (36) months after a
Change in Control (as defined in Section 11) shall have occurred.  Additionally,
on each annual anniversary date from the Effective Date, the Employee's term of
employment shall be extended for an additional one-year period beyond the then
effective expiration date provided the Board determines in a duly adopted
resolution that the performance of the Employee has met the Board's requirements
and standards, and that this Agreement shall be extended.

     6.   Loyalty: Noncompetition.
          ----------------------- 

          (a) During the period of his employment hereunder and except for
illnesses, reasonable vacation periods, and reasonable leaves of absence, the
Employee shall devote all his full business time, attention, skill, and efforts
to the faithful performance of his duties hereunder; provided, however, from
time to time, Employee may serve on the boards of directors of, and hold any
other offices or positions in, companies or organizations, which will not
present any conflict of interest with the Bank or any of its subsidiaries or
affiliates, or unfavorably affect the performance of Employee's duties pursuant
to this Agreement, or will not violated any applicable statute or regulation.
"Full business time" is hereby defined as that amount of time usually devoted to
like companies by similarly situated executive officers. During the term of his
employment under this Agreement, the Employee shall not engage in any business
or activity contrary to the business affairs or interests of the Bank, or be
gainfully employed in any other position or job other than as provided above.

          (b) Nothing contained in this Paragraph 6 shall be deemed to prevent
or limit the Employee's right to invest in the capital stock or other securities
of any business dissimilar from that of the Bank, or, solely as a passive or
minority investor, in any business.

                                      -2-
<PAGE>
 
     7.   Standards.  The Employee shall perform his duties under this Agreement
          ---------                                                             
in accordance with such reasonable standards as the Board may establish from
time to time. The Bank will provide Employee with the working facilities and
staff customary for similar executives and necessary for him to perform his
duties.

     8.   Vacation and Sick Leave.  At such reasonable times as the Board shall
          -----------------------                                              
in its discretion permit, the Employee shall be entitled, without loss of pay,
to absent himself voluntarily from the performance of his employment under this
Agreement, all such voluntary absences to count as vacation time; provided that:

          (a) The Employee shall be entitled to an annual vacation in accordance
with the policies that the Board periodically establishes for senior management
employees of the Bank.

          (b) The Employee shall not receive any additional compensation from
the Bank on account of his failure to take a vacation or sick leave, and the
Employee shall not accumulate unused vacation or sick leave from one fiscal year
to the next, except in either case to the extent authorized by the Board.

          (c) In addition to the aforesaid paid vacations, the Employee shall be
entitled without loss of pay, to absent himself voluntarily from the performance
of his employment with the Bank for such additional periods of time and for such
valid and legitimate reasons as the Board may in its discretion determine.
Further, the Board may grant to the Employee a leave or leaves of absence, with
or without pay, at such time or times and upon such terms and conditions as such
Board in its discretion may determine.

          (d) In addition, the Employee shall be entitled to an annual sick
leave benefit as established by the Board.

     9.   Termination and Termination Pay.  Subject to Section 11 hereof, the
          -------------------------------                                    
Employee's employment hereunder may be terminated under the following
circumstances:

          (a) Death. The Employee's employment under this Agreement shall
              -----                                                      
terminate upon his death during the term of this Agreement, in which event the
Employee's estate shall be entitled to receive the compensation due the Employee
through the last day of the calendar month in which his death occurred.

          (b) Disability.  If the Employee shall become disabled or
              ----------                                           
incapacitated to the extent that he is unable to perform his duties hereunder,
by reason of a medically determinable physical or mental impairment, as
determined by a doctor engaged by the Board of Directors, Employee shall
nevertheless continue to receive the following percentages of his compensation,
inclusive of any benefits which may be payable to Employee under the provisions
of disability insurance coverage in effect for Bank employees, under

                                      -3-
<PAGE>
 
Paragraph 2 of this Agreement for the following periods of his disability: 60%
for the remaining term of this Agreement. Upon returning to active full-time
employment, the Employee's full compensation as set forth in this Agreement
shall be reinstated. In the event that said Employee returns to active
employment on other than a full-time basis, then his compensation (as set forth
in Paragraph 2 of this Agreement) shall be reduced in proportion to the time
spent in said employment, or as shall otherwise be agreed to by the parties.

          (c) Just Cause.  The Board may, by written notice to the Employee,
              ----------                                                    
immediately terminate his employment at any time, for Just Cause.  The Employee
shall have no right to receive compensation or other benefits for any period
after termination for Just Cause.  Termination for "Just Cause" shall mean
termination because of, in the good faith determination of the Board, the
Employee's personal dishonesty, incompetence, willful misconduct, breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule or regulation (other than traffic
violations or similar offenses) or final cease-and-desist order, or material
breach of any provision of this Agreement.  No act, or failure to act, on the
Employee's part shall be considered "willful" unless he has acted, or failed to
act, with an absence of good faith and without a reasonable belief that his
action or failure to act was in the best interest of the Bank.  Notwithstanding
the foregoing, (i) the Employee shall not be deemed to have been terminated for
Just Cause unless there shall have been delivered to the Employee a copy of a
resolution duly adopted by the affirmative vote of not less than a majority of
the entire membership of the Board at a meeting of the Board called and held for
that purpose (after reasonable notice to the Employee and an opportunity for the
Employee to be heard before the Board), finding that in the good faith opinion
of the Board the Employee was guilty of conduct set forth above in the third
sentence of this Subsection (c) and specifying the particulars thereof in
detail.

          (d) Without Just Cause.  Subject to Section 11 hereof, the Board may,
              ------------------                                               
by written notice to the Employee, immediately terminate his employment at any
time for a reason other than Just Cause, in which event the Employee shall be
entitled to receive the following compensation and benefits: (i) the salary
provided pursuant to Section 2 hereof , up to the date of termination of the
term (including any renewal term) of this Agreement (the "Expiration Date"),
plus said salary for an additional 12-month period, but in no event in excess of
three years' salary and (ii) the cost to the Employee of obtaining all health,
life, disability and other benefits which the Employee would have been eligible
to participate in through the Expiration Date based upon the benefit levels
substantially equal to those that the Bank provided for the Employee at the date
of termination of employment.  Said sum shall be paid, at the option of the
Employee, either (I) in periodic payments over  the  remaining term of this
Agreement,  as if the

                                      -4-
<PAGE>
 
Employee's employment had not been terminated, or (II) in one lump sum within
ten (10) days of such termination.

          (e) Termination or Suspension Under Federal Law. (1) If the Employee
              -------------------------------------------                     
is removed and/or permanently prohibited from participating in the conduct of
the Bank's affairs by an order issued under Sections 8 (e) (4) or 8 (g) (1) of
the Federal Deposit Insurance Act ("FDIC") (12 U.S.C. 1818(e) (4) and (g) (1)),
all obligations of the Bank under this Agreement shall terminate, as of the
effective date of the order, but vested rights of the parties shall not be
affected.

          (2) If the Bank is in default (as defined in Section 3 (x) (1) of
FDIA), all obligations under this Agreement shall terminate as of the date of
default; however, this Paragraph shall not affect the vested rights of the
parties.

          (3) All obligations under this Agreement shall terminate, except to
the extent that continuation of this Agreement is necessary for the continued
operation of the Bank: (I) by the Commissioner of Banks of the Commonwealth of
Massachusetts (the "Commissioner") or his or her designee, at the time that the
Federal Deposit Insurance Corporation ("FDIC") enters into an agreement to
provide assistance to or on behalf of the Bank under the authority contained in
Section 13(c) of FDIA; or (ii) by the commissioner, or his or her designee, at
the time that the Commissioner, or his or her designee approves a supervisory
merger to resolve problems related to operation of the Bank or when the Bank is
determined by the Commissioner to be in an unsafe or unsound condition.  Such
action shall not affect any vested rights of the parties.

          (4) If a notice served under Section 8 (e) (3) or (g) (1) of the FDIA
(12 U.S.C. 1818(e)(3) or (g)(1)) suspends and/or temporarily prohibits the
Employee from participating in the conduct of the Bank's affairs, the Bank's
obligations under this Agreement shall be suspended as of the date of such
service, unless stayed by appropriate proceedings.  If the charges in the notice
are dismissed, the Bank shall (I) pay the Employee all or part of the
compensation withhold while its contract obligations were suspended,, and (ii)
reinstate (in whole or -in part) any of its obligations which were suspended.

          (f) Voluntary Termination by Employee.  Subject to Section 11 hereof,
              ---------------------------------                                
the Employee may voluntarily terminate employment with the Bank during the term
of this Agreement, upon at least 60 days' prior written notice to the Board of
Directors, in which case the Employee shall receive only his compensation,
vested rights and employee benefits up to the date of his termination.

     10.  No Mitigation.  The Employee shall not be required to mitigate the
          -------------                                                     
amount of any payment provided for in this Agreement

                                      -5-
<PAGE>
 
by seeking other employment or otherwise and no such payment shall be offset or
reduced by the amount of any compensation or benefits provided to the Employee
in any subsequent employment.

     11.  Change in Control.
          ----------------- 

          (a) Notwithstanding any provision herein to the contrary, if the
Employee's employment under this Agreement is terminated by the Bank, without
the Employee's prior written consent and for a reason other than Just Cause, in
connection with or within twelve (12) months after any change in control of the
Bank, the Employee shall be paid an amount equal to the difference between (I)
the product of 2.99 times his "base amount" as defined in Section 28OG(b) (3) of
the Internal Revenue Code of 1986, as amended (the "Code") and regulations
promulgated thereunder, and (ii).the sum of any other parachute payments (as
defined under Section 28OG(b) (2) of the Code) that the Employee receives on
account of the change in control.  Said sum shall be paid in one lump sum within
ten (10) days of such termination.

     The term "change in control" shall mean (1) the ownership, holding or power
to vote more than 25% of the Bank's voting stock-, (2) the control of the
election of a majority of the Bank's directors, (3) the exercise of a
controlling influence over the management or policies of the Bank by any person
or by persons acting as a "group" (within the meaning of Section 13(d) of the
Securities Exchange Act of 1934), or (4) during any period of two consecutive
years, individuals (the "Continuing Directors") who at the beginning of such
period constitute the Board of Directors of the Bank (the "Incumbent Board")
cease for any reason to constitute at least two-thirds thereof, provided that
any individual whose election or nomination for election as a member of the
Incumbent Board was approved by a vote of at least two-thirds of the Continuing
Directors then in office shall be considered a Continuing Director. The term
"person" means an individual other than the Employee, or a corporation,
partnership, trust, association, joint venture, pool, syndicate, sole
proprietorship, unincorporated organization or any other form of entity not
specifically listed herein.

          (b) Notwithstanding any other provision of this Agreement to the
contrary, the Employee may voluntarily terminate his employment under this
Agreement within twelve (12) months following a change in control of the Bank,
and the Employee shall thereupon be entitled to receive the payment described in
Section 11(a) of this Agreement, upon the occurrence of any of the following
events, or within ninety (90) days thereafter, which have not been consented to
in advance by the Employee in writing: (i) the requirement that the Employee
move his personal residence, or perform his principal executive functions, more
than thirty-five (35) miles from Sandwich, Massachusetts; (ii) a material
reduction in the Employee's base compensation as in effect on the date of the

                                      -6-
<PAGE>
 
change in control or as the same may be increased from time to time; (iii) the
failure by the Bank to continue to provide the Employee with compensation and
benefits provided for under this Agreement, as the same may be increased from
time to time, or with benefits substantially similar to those provided to him
under any of the employee benefit plans in which the Employee now or hereafter
becomes a participant, or the taking of any action by the Bank which would
directly or indirectly reduce any of such benefits or deprive the Employee of
any material fringe benefit enjoyed by him at the time of the change in control;
(iv) the assignment to the Employee of duties and responsibilities materially
different from those normally associated with his position as referenced at
Section 1; (v) a failure to elect or reelect the Employee to the Board of
Directors of the Bank, if the Employee is serving on the Board on the date of
the change in control; or (vi) a material diminution or reduction in the
Employee's responsibilities or authority (including reporting responsibilities)
in connection with his employment with the Bank.

          (c) Any payments made to the Employee pursuant to this Agreement, or
otherwise, are subject to and conditioned upon their compliance with 12 U.S.C.
Section 1828(k) and any regulations promulgated thereunder.

          (d) Within five business days before or after a change in control as
defined in 511(a) of this Agreement, the Bank shall (I) deposit, or cause to be
deposited, in trust (the "Trust) an amount equal to 2.99 times the Employee's
"base amount" as defined in Section 28OG(b) (3) of the Code, and (ii) provide
the trustee of the Trust with a written direction to hold said amount and any
investment return thereon in a segregated account for the benefit of the
Employee, and to follow the procedures set forth in the next paragraph as to the
payment of such amounts from the Trust.

          During the 12-consecutive month period following the date on which the
Bank makes the deposit referred to in the preceding paragraph, the Employee may
provide the trustee of the Trust with a written notice requesting that the
trustee pay to the Employee an amount designated in the notice as being payable
pursuant to Section 11 (a) or (b).   Within three business days after receiving
said notice, the trustee of the Trust shall send a copy of the notice to the
Bank via overnight and registered mail return receipt requested.  On the tenth
(10th) business day after mailing said notice to the Bank, the trustee of the
Trust shall pay the Employee the amount designated therein in immediately
available funds, unless prior thereto the Bank provides the trustee with a
written notice directing the trustee to withhold such payment.   In the latter
event, the trustee shall submit the dispute to nonappealable binding arbitration
for a determination of the amount payable to the Employee pursuant to Section 11
(a) or (b) hereof, and the costs of such arbitration (including any legal fees
and expenses incurred by the Employee) shall be paid by the Bank. The trustee
shall choose the arbitrator to settle the dispute, and such arbitrator shall be
bound by the rules of the American Arbitration Association in making his
determination. The parties and the                                      

                                      -7-
<PAGE>
 
trustee shall be bound by the results of the arbitration and, within 3 days of
the determination by the arbitrator, the trustee shall pay from the Trust the
amounts required to be paid to the Employee and/or the Bank, and in no event
shall the trustee be liable to either party for making the payments as
determined by the arbitrator.

          Upon the earlier of (I) any payment from the Trust to the Employee, or
(ii) the date 12 months after the date on which the Bank makes the deposit
referred to in the first paragraph of this subsection (d), the trustee of the
Trust shall pay to the Bank the entire balance remaining in the segregated
account maintained for the benefit of the Employee.  The Employee shall
thereafter have no further rights under this Section 11, no further interest in
the Trust pursuant to this Agreement, and no further rights or claims against
the Bank pursuant to this Agreement.

          (e) In the event that any dispute arises between the Employee and the
Bank as to the terms or interpretation of this Agreement, including this Section
11, whether instituted by formal legal proceedings or otherwise, including any
action that the Employee takes to enforce the terms of this Section 11 or to
defend against any action taken by the Bank, the Employee shall be reimbursed
for all costs and expenses, including reasonable attorneys' fees, arising from
such dispute, proceedings or actions, provided that the Employee shall obtain a
final judgement by a court of competent jurisdiction in favor of the Employee.
Such reimbursement shall be paid within ten (10) days of Employee's furnishing
to the Bank written evidence, which may be in the form, among other things, of a
canceled check or receipt, of any costs or expenses incurred by the Employee.

     12.  Successors and Assigns.
          ---------------------- 

          (a) This Agreement shall inure to the benefit of and be binding upon
any corporate or other successor of the Bank which shall acquire, directly or
indirectly, by merger, consolidation, purchase or otherwise, all or
substantially all of the assets or stock of the Bank.

          (b) Since the Bank is contracting for the unique and personal skills
of the Employee, the Employee shall be precluded from assigning or delegating
his rights or duties hereunder without first obtaining the written consent of
the Bank.

     13.  Amendments.  No amendments or additions to this Agreement shall be
          ----------

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS AGREEMENT entered into this 18th day of July, 1994, by and between The
Sandwich Co-operative Bank (the "Bank") and Dana S. Briggs (the "Employee"), and
hereby replaces the Employment Agreement between the Bank and the Employee, as
first dated July 17, 1989 (as amended).

     WHEREAS, the Employee has heretofore been employed by the Bank as Senior
Vice President and Administration Officer and is experienced in all phases of
the business of the Bank; and

     WHEREAS, the parties desire by this writing to set forth the
continuing employment relationship of the Bank and the Employee.

     NOW, THEREFORE, it is AGREED as follows:

     1.   Employment.  The Employee is employed as the Senior Vice President and
          ----------                                                            
Administration Officer of the Bank.  The Employee shall render such
administrative and management services for the Bank as are currently rendered
and as are customarily performed by persons situated in a similar executive
capacity.  The Employee shall also promote, by entertainment or otherwise, as
and to the extent permitted by law, the business of the Bank.  The Employee's
other duties shall be such as the Board of Directors of the Bank ("Board") may
from time to time reasonably direct, including normal duties as an officer of
the Bank.

     2.   Base Compensation.  The Bank agrees to pay the Employee during the
          -----------------                                                 
term of this Agreement a salary at the rate of $76,000 per annum, payable in
cash not less frequently than monthly.  The Board shall review, not less often
than annually, the rate of the Employee's salary, and in its sole discretion may
decide to increase his salary.

     3.   Discretionary Bonuses.  The Employee shall participate in an equitable
          ---------------------                                                 
manner with all other senior management employees of the Bank in discretionary
bonuses that the Board may award from time to time to the Bank's senior
management employees. No other compensation provided for in this Agreement shall
be deemed a substitute for the Employee's right to participate in such
discretionary bonuses.

     4.   (a) Participation in Retirement, Medical and Other Plans. The Employee
              ---------------------------------------------------- 
shall participate in any plan that the Bank maintains for the benefit of its
employees if the plan relates to (i) pension, profit-sharing, or other
retirement benefits, (ii) medical insurance or the reimbursement of medical or
dependent care expenses, or (iii) other group benefits, including disability and
life insurance plans.

          (b) Employee Benefits: Expenses.    The Employee shall participate  in
              ---------------------------
any  fringe  benefits  which  are  or  may  become
<PAGE>
 
available to the Bank's senior management employees, including for example: any
stock option or incentive compensation plans, club memberships, and any other
benefits which are commensurate with the responsibilities and functions to be
performed by the Employee under this Agreement. The Employee shall be reimbursed
for all reasonable out-of-pocket business expenses which he shall incur in
connection with his services under this Agreement upon substantiation of such
expenses in accordance with the policies of the Bank.

     5.   Term.  The Bank hereby employs the Employee, and the Employee hereby
          ----                                                                
accepts such employment under this Agreement, for the period commencing on July
18, 1994 and ending 36 months thereafter on July 17, 1997 (or such earlier date
as is determined in accordance with Section 9) ; provided that notwithstanding
any determination by the Bank not to extend the term of this Agreement, said
term shall not expire prior to the expiration of thirty-six (36) months after a
Change in Control (as defined in Section 11) shall have occurred.  Additionally,
on each annual anniversary date from the Effective Date, the Employee's term of
employment shall be extended for an additional one-year period beyond the then
effective expiration date provided the Board determines in a duly adopted
resolution that the performance of the Employee has met the Board's requirements
and standards, and that this Agreement shall be extended.

     6.   Loyalty: Noncompetition.
          ----------------------- 

          (a) During the period of his employment hereunder and except for
illnesses, reasonable vacation periods, and reasonable leaves of absence, the
Employee shall devote all his full business time, attention, skill, and efforts
to the faithful performance of his duties hereunder; provided, however, from
time to time, Employee may serve on the boards of directors of, and hold any
other offices or positions in, companies or organizations, which will not
present any conflict of interest with the Bank or any of its subsidiaries or
affiliates, or unfavorably affect the performance of Employee's duties pursuant
to this Agreement, or will not violated any applicable statute or regulation.
"Full business time" is hereby defined as that amount of time usually devoted to
like companies by similarly situated executive officers. During the term of his
employment under this Agreement, the Employee shall not engage in any business
or activity contrary to the business affairs or interests of the Bank, or be
gainfully employed in any other position or job other than as provided above.

          (b) Nothing contained in this Paragraph 6 shall be deemed to prevent
or limit the Employee's right to invest in the capital stock or other securities
of any business dissimilar from that of the Bank, or, solely as a passive or
minority investor, in any business.

                                      -2-
<PAGE>
 
     7.   Standards.  The Employee shall perform his duties under this Agreement
          ---------                                                             
in accordance with such reasonable standards as the Board may establish from
time to time. The Bank will provide Employee with the working facilities and
staff customary for similar executives and necessary for him to perform his
duties.

     8.   Vacation and Sick Leave.  At such reasonable times as the Board shall
          -----------------------                                              
in its discretion permit, the Employee shall be entitled, without loss of pay,
to absent himself voluntarily from the performance of his employment under this
Agreement, all such voluntary absences to count as vacation time; provided that:

          (a) The Employee shall be entitled to an annual vacation in accordance
with the policies that the Board periodically establishes for senior management
employees of the Bank.

          (b) The Employee shall not receive any additional compensation from
the Bank on account of his failure to take a vacation or sick leave, and the
Employee shall not accumulate unused vacation or sick leave from one fiscal year
to the next, except in either case to the extent authorized by the Board.

          (c) In addition to the aforesaid paid vacations, the Employee shall be
entitled without loss of pay, to absent himself voluntarily from the performance
of his employment with the Bank for such additional periods of time and for such
valid and legitimate reasons as the Board may in its discretion determine.
Further, the Board may grant to the Employee a leave or leaves of absence, with
or without pay, at such time or times and upon such terms and conditions as such
Board in its discretion may determine.

          (d) In addition, the Employee shall be entitled to an annual sick
leave benefit as established by the Board.

     9.   Termination and Termination Pay.  Subject to Section 11 hereof, the
          -------------------------------                                    
Employee's employment hereunder may be terminated under the following
circumstances:

          (a) Death. The Employee's employment under this Agreement shall
              -----                                                      
terminate upon his death during the term of this Agreement, in which event the
Employee's estate shall be entitled to receive the compensation due the Employee
through the last day of the calendar month in which his death occurred.

          (b) Disability.  If the Employee shall become disabled or
              ----------                                           
incapacitated to the extent that he is unable to perform his duties hereunder,
by reason of a medically determinable physical or mental impairment, as
determined by a doctor engaged by the Board of Directors, Employee shall
nevertheless continue to receive the following percentages of his compensation,
inclusive of any benefits which may be payable to Employee under the provisions
of disability insurance coverage in effect for Bank employees, under

                                      -3-
<PAGE>
 
Paragraph 2 of this Agreement for the following periods of his disability: 60%
for the remaining term of this Agreement. Upon returning to active full-time
employment, the Employee's full compensation as set forth in this Agreement
shall be reinstated. In the event that said Employee returns to active
employment on other than a full-time basis, then his compensation (as set forth
in Paragraph 2 of this Agreement) shall be reduced in proportion to the time
spent in said employment, or as shall otherwise be agreed to by the parties.

          (c) Just Cause.  The Board may, by written notice to the Employee,
              ----------                                                    
immediately terminate his employment at any time, for Just Cause. The Employee
shall have no right to receive compensation or other benefits for any period
after termination for Just Cause. Termination for "Just Cause" shall mean
termination because of, in the good faith determination of the Board, the
Employee's personal dishonesty, incompetence, willful misconduct, breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule or regulation (other than traffic
violations or similar offenses) or final cease-and-desist order, or material
breach of any provision of this Agreement. No act, or failure to act, on the
Employee's part shall be considered "willful" unless he has acted, or failed to
act, with an absence of good faith and without a reasonable belief that his
action or failure to act was in the best interest of the Bank. Notwithstanding
the foregoing, (i) the Employee shall not be deemed to have been terminated for
Just Cause unless there shall have been delivered to the Employee a copy of a
resolution duly adopted by the affirmative vote of not less than a majority of
the entire membership of the Board at a meeting of the Board called and held for
that purpose (after reasonable notice to the Employee and an opportunity for the
Employee to be heard before the Board), finding that in the good faith opinion
of the Board the Employee was guilty of conduct set forth above in the third
sentence of this Subsection (c) and specifying the particulars thereof in
detail.

          (d) Without Just Cause.  Subject to Section 11 hereof, the Board may,
              ------------------                                               
by written notice to the Employee, immediately terminate his employment at any
time for a reason other than Just Cause, in which event the Employee shall be
entitled to receive the following compensation and benefits: (i) the salary
provided pursuant to Section 2 hereof , up to the date of termination of the
term (including any renewal term) of this Agreement (the "Expiration Date"),
plus said salary for an additional 12-month period, but in no event in excess of
three years' salary and (ii) the cost to the Employee of obtaining all health,
life, disability and other benefits which the Employee would have been eligible
to participate in through the Expiration Date based upon the benefit levels
substantially equal to those that the Bank provided for the Employee at the date
of termination of employment.  Said sum shall be paid, at the option of the
Employee, either (I) in periodic payments over  the  remaining term of this
Agreement,  as if the

                                      -4-
<PAGE>
 
Employee's employment had not been terminated, or (II) in one lump sum within
ten (10) days of such termination.

          (e) Termination or Suspension Under Federal Law. (1) If the Employee
              -------------------------------------------                     
is removed and/or permanently' prohibited from participating in the conduct of
the Bank's affairs by an order issued under Sections 8 (e) (4) or 8 (g) (1) of
the Federal Deposit Insurance Act ("FDIA") (12 U.S.C. 1818(e)(4) and (g)(1)),
all obligations of the Bank under this Agreement shall terminate, as of the
effective date of the order, but vested rights of the parties shall not be
affected.

          (2) If the Bank is in default (as defined in Section 3 (x) (1) of
FDIA), all obligations under this Agreement shall terminate as of the date of
default; however, this Paragraph shall not affect the vested rights of the
parties.

          (3) All obligations under this Agreement shall terminate, except to
the extent that continuation of this Agreement is necessary for the continued
operation of the Bank: (I) by the Commissioner of Banks of the Commonwealth of
Massachusetts (the "Commissioner") or his or her designee, at the time that the
Federal Deposit Insurance Corporation ("FDIC") enters into an agreement to
provide assistance to or on behalf of the Bank under the authority contained in
Section 13(c) of FDIA; or (ii) by the commissioner, or his or her designee, at
the time that the commissioner, or his or her designee approves a supervisory
merger to resolve problems related to operation of the Bank or when the Bank is
determined by the Commissioner to be in an unsafe or unsound condition.  Such
action shall not affect any vested rights of the parties.

          (4) If a notice served under Section 8(e)(3) or (g)(1) of the FDIA (12
U.S.C. 1818(e)(3) or (g)(1)) suspends and/or temporarily prohibits the Employee
from participating in the conduct of the Bank's affairs, the Bank's obligations
under this Agreement shall be suspended as of the date of such service, unless
stayed by appropriate proceedings.  If the charges in the notice are dismissed,
the Bank shall (I) pay the Employee all or part of the compensation withheld
while its contract obligations were suspended, and (ii) reinstate (in whole or
in part) any of its obligations which were suspended.

          (f) Voluntary Termination by Employee.  Subject to Section 11 hereof,
              ---------------------------------                                
the Employee may voluntarily terminate employment with the Bank during the term
of this Agreement, upon at least 60 days' prior written notice to the Board of
Directors, in which case the Employee shall receive only his compensation,
vested rights and employee benefits up to the date of his termination.

     10.  No Mitigation.  The Employee shall not be required to mitigate the
          -------------                                                     
amount of any payment provided for in this Agreement

                                      -5-
<PAGE>
 
by seeking other employment or otherwise and no such payment shall be offset or
reduced by the amount of any compensation or benefits provided to the Employee
in any subsequent employment.

     11.  Change in Control.
          ----------------- 

          (a) Notwithstanding any provision herein to the contrary, if the
Employee's employment under this Agreement is terminated by the Bank, without
the Employee's prior written consent and for a reason other than Just Cause, in
connection with or within twelve (12) months after any change in control of the
Bank, the Employee shall be paid an amount equal to the difference between (I)
the product of 2.99 times his "base amount" as defined in Section 28OG(b) (3) of
the Internal Revenue Code of 1986, as amended (the "Code") and regulations
promulgated thereunder, and (ii) the sum of any other parachute payments (as
defined under Section 28OG(b) (2) of the Code) that the Employee receives on
account of the change in control.  Said sum shall be paid in one lump sum within
ten (10) days of such termination.

     The term "change in control" shall mean (1) the ownership, holding or power
to vote more than 25% of the Bank's voting stock, (2) the control of the
election of a majority of the Bank's directors, (3) the exercise of a
controlling influence over the management or policies of the Bank by any person
or by persons acting as a "group" (within the meaning of Section 13(d) of the
Securities Exchange Act of 1934), or (4) during any period of two consecutive
years, individuals (the "Continuing Directors") who at the beginning of such
period constitute the Board of Directors of the Bank (the "Incumbent Board")
cease for any reason to constitute at least two-thirds thereof, provided that
any individual whose election or nomination for election as a member of the
Incumbent Board was approved by a vote of at least two-thirds of the Continuing
Directors then in office shall be considered a Continuing Director.  The term
"person" means an individual other than the Employee, or a corporation,
partnership, trust, association, joint venture, pool, syndicate, sole
proprietorship, unincorporated organization or any other form of entity not
specifically listed herein.

          (b) Notwithstanding any other provision of this Agreement to the
contrary, the Employee may voluntarily terminate his employment under this
Agreement within twelve (12) months following a change in control of the Bank,
and the Employee shall thereupon be entitled to receive the payment described in
Section 11(a) of this Agreement, upon the occurrence of any of the following
events, or within ninety (90) days thereafter, which have not been consented to
in advance by the Employee in writing: (I) the requirement that the Employee
move his personal residence, or perform his principal executive functions, more
than thirty-five (35) miles from Sandwich, Massachusetts; (ii) a material
reduction in the Employee's base compensation as in effect on the date of the

                                      -6-
<PAGE>
 
change in control or as the same may be increased from time to time; (iii) the
failure by the Bank to continue to provide the Employee with compensation and
benefits provided for under this Agreement, as the same may be increased from
time to time, or with benefits substantially similar to those provided to him
under any of the employee benefit plans in which the Employee now or hereafter
becomes a participant, or the taking of any action by the Bank which would
directly or indirectly reduce any of such benefits or deprive the Employee of
any material fringe benefit enjoyed by him at the time of the change in control;
(iv) the assignment to the Employee of duties and responsibilities materially
different from those normally associated with his position as referenced at
Section 1; or (v) a material diminution or reduction in the Employee's
responsibilities or authority (including reporting responsibilities) in
connection with his employment with the Bank.

          (c) Any payments made to the Employee pursuant to this Agreement, or
otherwise, are subject to and conditioned upon their compliance with 12 U.S.C.
Section 1828(k) and any regulations promulgated thereunder.

          (d) Within five business days before or after a change in control as
defined in (S)11(a) of this Agreement, the Bank shall (i) deposit, or cause to
be deposited, in trust (the "Trust) an amount equal to 2.99 times the Employee's
"base amount" as defined in Section 28OG(b) (3) of the Code, and (ii) provide
the trustee of the Trust with a written direction to hold said amount and any
investment return thereon in a segregated account for the benefit of the
Employee, and to follow the procedures set forth in the next paragraph as to the
payment of such amounts from the Trust.

          During the 12-consecutive month period following the date on which the
Bank makes the deposit referred to in the preceding paragraph, the Employee may
provide the trustee of the Trust with a written notice requesting that the
trustee pay to the Employee an amount designated in the notice as being payable
pursuant to Section 11(a) or (b).  Within three business days after receiving
said notice, the trustee of the Trust shall send a copy of the notice to the
Bank via overnight and registered mail return receipt requested.  On the tenth
(10th) business day after mailing said notice to the Bank, the trustee of the
Trust shall pay the Employee the amount designated therein in immediately
available funds, unless prior thereto the Bank provides the trustee with a
written notice directing the trustee to withhold such payment.  In the latter
event, the trustee shall submit the dispute to nonappealable binding arbitration
for a determination of the amount payable to the Employee pursuant to Section
11(a) or (b) hereof, and the costs of such arbitration (including any legal fees
and expenses incurred by the Employee) shall be paid by the Bank.  The trustee
shall choose the arbitrator to settle the dispute, and such arbitrator shall be
bound by the rules of the American Arbitration Association in making his
determination.  The parties and the

                                      -7-

trustee shall be bound by the results of the arbitration and, within 3 days of
the determination by the arbitrator, the trustee shall pay from the Trust the
amounts required to be paid to the Employee and/or the Bank, and in no event
shall the trustee be liable to either party for making the payments as
determined by the arbitrator.

          Upon the earlier of (I) any payment from the Trust to the Employee, or
(ii) the date 12 months after the date on which the Bank makes the deposit
referred to in the first paragraph of this subsection (d), the trustee of the
Trust shall pay to the Bank the entire balance remaining in the segregated
account maintained for the benefit of the Employee.  The Employee shall
thereafter have no further rights under this Section 11, no further interest in
the Trust pursuant to this Agreement, and no further rights or claims against
the Bank pursuant to this Agreement.

          (e) In the event that any dispute arises between the Employee and the
Bank as to the terms or interpretation of this Agreement, including this Section
11, whether instituted by formal legal proceedings or otherwise, including any
action that the Employee takes to enforce the terms of this Section 11 or to
defend against any action taken by the Bank, the Employee shall be reimbursed
for all costs and expenses, including reasonable attorneys' fees, arising from
such dispute, proceedings or actions, provided that the Employee shall obtain a
final judgement by a court of competent jurisdiction in favor of the Employee.
Such reimbursement shall be paid within ten (10) days of Employee's furnishing
to the Bank written evidence, which may be in the form, among other things, of a
canceled check or receipt, of any costs or expenses incurred by the Employee.

     12.  Successors and Assigns.
          ---------------------- 

          (a) This Agreement shall inure to the benefit of and be binding upon
any corporate or other successor of the Bank which shall acquire, directly or
indirectly, by merger, consolidation, purchase or otherwise, all or
substantially all of the assets or stock of the Bank.

          (b) Since the Bank is contracting for the unique and personal skills
of the Employee, the Employee shall be precluded from assigning or delegating
his rights or duties hereunder without first obtaining the written consent of
the Bank.

     13.  Amendments.  No amendments or additions to this Agreement shall be

having been exercised in full, the unpurchased shares which were subject thereto
shall, unless the Plan shall have been terminated, be available for the grant of
other Options under the Plan.

     4.  ADMINISTRATION OF THE PLAN.

     (a) Composition of Option Committee.  The Plan shall be administered by an
Option Committee (the "Committee") consisting of not less than three directors
of the Bank appointed by the Board.  All persons designated as members of the
Committee shall be "disinterested persons" within the meaning of Rule 16b-3 of
the Securities and Exchange Act of 1934.

     (b) Powers of the Committee.  The Committee is authorized (but only to the
extent not contrary to the express provisions of the Plan or to resolutions
adopted by the Board) to interpret the Plan, to prescribe, amend and rescind
rules and regulations relating to the Plan, to determine the form and content of
Options to be issued under the Plan and to make other determinations necessary
or advisable for the administration of the Plan, and shall have and may exercise
such other power and authority as may be delegated to it by the Board from time
to time.  A majority of the entire Committee shall constitute a quorum and the
action of a majority of the members present at any meeting at which a quorum is
present shall be deemed the action of the Committee.

     (c)  Effect of Committee's Decision.  All decisions, determinations and
interpretations of the Committee shall be final and conclusive on all persons
affected thereby.

     5.  ELIGIBILITY.

     Options may be granted to such Employees of the Bank or any present or
future Parent or Subsidiary as shall be designated by the Committee.  An
Employee who has been granted an Option may, if otherwise eligible, be granted
an additional Option or Options.

     The aggregate fair market value (determined pursuant to Section 7 hereof as
of the date the Option is granted) of the Shares for which any Employee may be
granted Options in any calendar year (under all Incentive Stock Option Plans, as
defined in Section 422A of the Code, of the Bank or any present or future Parent
or Subsidiary of the Bank), for options granted prior to December 31, 1986,
shall not exceed $100,000, plus any unused limit carryover to such year, as
defined in Section 422A(c) of the Code.  The aggregate fair market value
(determined as of the date the option is granted) of the Shares with respect to
which Incentive Stock Options granted after December 31, 1986, are exercisable
for the first time by an employee during any calendar year shall not exceed
$100,000.  Notwithstanding the prior provisions of this paragraph, the Committee
may grant Options in excess of the foregoing limitations, provided said Options
shall be clearly and specifically designated as not being Incentive Stock
Options, as defined in Section 422A of the Code.

     No Option which qualifies as an Incentive Stock Option (for purposes of
this paragraph 5 called "New Option"), and was granted prior to December 31,
1986, shall be exercisable while there is outstanding any Incentive Stock Option
(as defined in Section 422A of the Code) which was granted, before the granting
of the New Option, to the Employee to whom the New Option is granted.  A
previously granted Incentive Stock Option, granted prior to December 31, 1986,
shall be treated as outstanding until such prior option is exercised in full or
expires by reason of lapse in time.

                                      -3-
<PAGE>
 
     6.  TERM OF PLAN; TERM OF OPTIONS.

     (a)  The Plan shall continue in effect for a term of ten years from its 
Effective Date, unless sooner terminated pursuant to paragraph 16.  No Option
shall be granted under the Plan after ten years from the Effective Date.

     (b)  The term of each Option granted under the Plan shall be established by
the Committee, but shall not exceed 10 years, provided however that in the case
of an Employee who owns stock representing more than ten percent of the Bank's
outstanding Common Stock at the time the Option is granted, the term of such
Option shall not exceed five years.

     7.  OPTION PRICE.

     The price per share at which each Option granted under the Plan may be
exercised shall not, as to any particular Option, be less than the fair market
value of the stock at the time such Option is granted.  In the case of an
Employee who owns stock representing more than ten percent of the Bank's 
outstanding Common Stock at the time the Option is granted, the Option price
shall not be less than 110% of the fair market value of the stock at the time
the Option is granted. If the Common Stock is traded otherwise than on a
national securities exchange at the time of the granting of an Option, then the
price per share shall be not less than the mean between the bid and asked price
on the date the Option is granted or, if there is no bid and asked price on said
date, then on the next prior business day on which there was a bid and asked
price. If no such bid and asked price is available, then the price per share
shall be determined by the Committee. If the Common Stock is listed on a
national securities exchange (including the NASDAQ national market) at the time
of granting an Option, then the price per share shall be not less than the
average of the highest and lowest selling price on such exchange on the date
such Option is granted or if there were no sales on said date, then the price
shall be not less than the mean between the bid and asked price on such date.

     8.  EXERCISE OF OPTION.

     (a)  Procedure for Exercise.  Any Option granted hereunder shall be
exercisable at such times and under such conditions as shall be permissible
under the terms of the Plan and of the Option granted to an Optionee.  An Option
may not be exercised for a fractional Share.

     An Option granted pursuant to the Plan may be exercised, subject to 
provisions relative to its termination and limitations on its exercise, from 
time to time only by (a) written notice of intent to exercise the Option with
respect to a specified number of shares, and (b) payment to the Bank
(contemporaneously with delivery of such notice), in cash, in Common Stock, or a
combination of cash and Common Stock, of the amount of the Option price for the
number of shares with respect to which the Option is then being exercised. Each
such notice and payment shall be delivered, or mailed by prepaid registered or
certified mail, addressed to the Treasurer of the Bank at the Bank's executive
offices. Common Stock utilized in full or partial payment of the exercise price
shall be valued at its fair market value at the date of exercise.

                                      -4-
<PAGE>
 
     (b)  Exercise During Employment or Following Death or Disability.  Unless
otherwise provided in the terms of an Option, an Option may be exercised by an
Optionee only while he is an Employee and has maintained Continuous Status As An
Employee since the date of the grant of the Option, or within 90 days after
termination of his status as an Employee (but not later than the date on which
the Option would otherwise expire), except if his Continuous Employment is
terminated by reason of (1) death, then to the extent that the Optionee would
have been entitled to exercise the Option immediately prior to his death, such
Option of the deceased Optionee may be exercised within two years from the date
of his death (but not later than the date on which the Option would otherwise
expire) by the personal representatives of his estate or person or persons to
whom his rights under such Option shall have passed by will or by laws of
descent and distribution, or (2) Permanent and Total Disability (as such term is
defined in Section 105(d)(4) of the Code), then to the extent that the Optionee
would have been entitled to exercise the Option immediately prior to his
Permanent and Total Disability, such Option may be exercised within one year
from the date of such Permanent and Total Disability, but not later than the
date on which the Option would otherwise expire.

     The Committee's determination whether an Optionee's employment has ceased,
and the effective date thereof, shall be final and conclusive on all persons
affected thereby.

     Notwithstanding any other provision of this Plan, if an Employee is
terminated for cause, all Options outstanding to such Employee shall be
cancelled as of the effective date of such termination and may not be exercised
thereafter.

      9.  CHANGE IN CONTROL.

     Notwithstanding the provisions of any Option which provides for its
exercise in installments as designated by the Committee, such Option shall
become immediately exercisable, and the Optionee shall, at the discretion of the
Committee, be entitled to receive cash in an amount equal to the excess of the
fair market value of the Common Stock (determined in accordance with Section 7)
subject to such Option over the Option price of such shares, in exchange for the
surrender of such options by the Optionee, in the event of a change in control
or offer to effect a change in control.  For purposes of this Section 9, "change
in control" shall refer to the acquisition of the beneficial ownership (as that
term is defined in Rule 13d-3 of the General Rules and Regulations under the
Securities Exchange Act of 1934) of 25 percent or more of the voting securities
of the Bank by any person or by persons acting as a group within the meaning of
Section 13(d) of the Securities Exchange Act of 1934; provided, however, that
for the purposes hereof no change in control or offer to effect a change in
control shall be deemed to have occurred if prior to the acquisition of, or
offer to acquire, 25 percent or more of the voting securities of Bank, the full
Board of Directors shall have adopted by not less than a two-thirds vote a
resolution specifically approving such acquisition or offer.  The term "person"
refers to an individual or a corporation, partnership, trust, association, joint
venture, pool, syndicate, sole proprietorship, unincorporated organization or
any other form of entity not specifically listed herein.  The decision of the
Committee as to whether a change in control or offer to effect a change in
control has occurred shall be conclusive and binding.

                                      -5-
<PAGE>
 
     10.  NON-TRANSFERABILITY OF OPTIONS.

     Options granted under the Plan may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by
the laws of descent and distribution.  An Option may be exercised, during the
lifetime of the Optionee, only by the Optionee.

     11.  EFFECT OF CHANGE IN STOCK SUBJECT TO THE PLAN.

     In the event that each of the outstanding shares of Common Stock (other
than shares held by dissenting shareholders) shall be changed into or exchanged
for a different number or kind of shares of stock of the Bank or of another
corporation (whether by reason of merger, consolidation, recapitalization,
reclassification, stock dividend, split-up, combination of shares, or
otherwise), then there shall be substituted for each share of Common Stock then
under Option or available for Option the number and kind of shares of stock into
which each outstanding share of Common Stock (other than shares held by
dissenting shareholders) shall be so changed or for which each such share shall
be so exchanged, together with an appropriate adjustment of the Option Price.

     In the event there shall be any change in the number of, or kind of, issued
shares of Common Stock, or of any stock or other securities into which such
Common Stock shall have been changed, or for which it shall have been exchanged,
then if the Committee shall, in its discretion, determine that such change
equitably requires an adjustment in the number, or kind, or Option Price of
shares then subject to an Option or available for Option, such adjustment shall
be made by the Board and shall be effective and binding for all purposes of the
Plan.

     12.  TIME OF GRANTING OPTIONS.

     The date of grant of an Option under the Plan shall, for all purposes, be
the date on which the Committee makes the determination of granting such Option.
Notice of the determination shall be given to each Employee to whom an Option is
so granted within a reasonable time after the date of such grant.

     13.  EFFECTIVE DATE.

     The Plan shall become effective upon the effective date of the conversion
of the Bank from mutual to stock form.  Options may be granted prior to
ratification of the Plan by the stockholders if the exercise of such Options is
subject to such stockholder ratification.  The Plan shall continue in effect for
a term of ten years from the Effective Date, unless sooner terminated under
paragraph 16 of the Plan.

     14.  APPROVAL BY STOCKHOLDERS.

     The Plan shall be approved by stockholders of the Bank within twelve (12)
months before or after the date it becomes effective.

     15.  MODIFICATION OF OPTIONS.

                                      -6-
<PAGE>
 
     At any time and from time to time the Board may authorize the Committee to
direct execution of an instrument providing for the modification of any
outstanding Option, provided no such modification, extension or renewal shall
confer on the holder of said Option any right or benefit which could not be 
conferred on him by the grant of a new Option at such time, or impair the Option
without the consent of the holder of the Option.

    16.  AMENDMENT AND TERMINATION OF THE PLAN.

     The Board may alter, suspend or discontinue the Plan except that no action
of the Board may increase (other than as provided in paragraph 11) the maximum
number of shares permitted to be optioned or become available for the granting
or Options under the Plan, or reduce the minimum Option price, or extend the
period within which Options may be exercised, unless such action of the Board
shall be subject to approval or ratification by the shareholders of the Bank.

     No action of the Board may, without the consent of the holder of the
Option, impair any then outstanding Option.

     17.  CONDITIONS UPON ISSUANCE OF SHARES.

     Shares shall not be issued with respect to any Option granted under the
Plan unless the issuance and delivery of such Shares shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the rules and regulations promulgated thereunder, any 
applicable state securities law, and the requirements of any stock exchange upon
which the Shares may then be listed.

     Inability of the Bank to obtain from any regulatory body or authority
deemed by the Bank's counsel to be necessary to the lawful issuance and sale of
any Shares hereunder shall relieve the Bank of any liability in respect of the
non-issuance or sale of such Shares.

     As a condition to the exercise of an Option, the Bank may require the
person exercising the Option to make such representations and warranties as may
be necessary to assure the availability of an exemption from the registration
requirements of federal or state securities law.

     18.  RESERVATION OF SHARES.

     The Bank, during the term of this Plan, will reserve and keep available a
number of Shares sufficient to satisfy the requirements of the Plan.

the first time by an Employee during any calendar year (under all incentive

present or future Parent or Subsidiary of the Bank) shall not exceed $100,000.
Notwithstanding the prior provisions of this paragraph, the Committee may grant
Options in excess of the foregoing limitations, in which case such Options

     7.   Exercise Price for Options.

     (a)  Limits on Committee Discretion. The Exercise Price as to any
particular Option granted under the Plan shall not be less than the Market Value
of the Optioned Shares on the date of grant. In the case of an Employee who owns

IO % of the Market Value of the Optioned Shares at the time the ISO is granted.

     (b)  Standards for Determining Exercise Price. If the Common Stock is
listed on a national securities exchange (including the NASDAQ National Market
System) on the date in question, then the Market Value per Share shall be not
less than the average of the highest and lowest selling price on such exchange
on such date, or if there were no sales on such date, then the Exercise Price
shall be not less than the mean between the bid and asked price on such date. If
the Common Stock is traded otherwise than on a national securities exchange on
the date in question, then the Market Value per Share shall be not less than the
mean between the bid and asked price on such date, or, if there is no bid and
asked price on such date, then on the next prior business day on which there was
a bid and asked price. If no such bid and asked price is available, then the
Market Value per Share shall be its fair market value as determined by the
Committee, in its sole and absolute discretion.

     8.   EXERCISE OF OPTIONS.

     (a)  Generally.  Any Option granted hereunder shall be exercisable at such
times and under such conditions as shall be permissible under the terms of the
Plan and of the Agreement granted to a Participant.  An Option may not be
exercised for a fractional Share.

     (b)  Procedure for Exercise. A Participant may exercise Options, subject to
provisions relative to its termination and limitations on its exercise, only by
(1) written notice of intent to exercise the Option with respect to a specified
number of Shares, and (2) payment to the Bank (contemporaneously with delivery
of such notice) in cash, in Common Stock, or a combination of cash and Common
Stock, of the amount of the Exercise Price for the number of Shares with respect
to which the Option is then being exercised. Each such notice (and payment where
required) shall be delivered, or mailed by prepaid registered or certified mail,
addressed to the Treasurer of the Bank at the Bank's executive offices. Common
Stock utilized in full or partial payment of the Exercise Price for Options
shall be valued at its Market Value at the date of exercise.

     (c)  Period of Exercisability. Except to the extent otherwise provided in
the terms of an Agreement, an Option may be exercised by a Participant only
while he is an Employee and has maintained Continuous Service from the date of
the grant of the Option, or within three months after termination of such
Continuous Service (but not later than the date on which the Option would
otherwise expire), except if the Employee's Continuous Service terminates by

                                       4
<PAGE>
 
reason of  --

     (1)  "Just Cause" which for purposes hereof shall have the meaning set
     forth in any unexpired employment or severance agreement between the
     Participant and the Bank (and, in the absence of any such agreement, shall
     mean termination because of the Employee's personal dishonesty,
     incompetence, willful misconduct, breach of fiduciary duty involving
     personal profit, intentional failure to perform stated duties, willful
     violation of any law, rule or regulation (other than traffic violations or
     similar offenses) or final cease-and-desist order), then the Participant's
     rights to exercise such Option shall expire on the date of such
     termination;

     (2)  death, then to the extent that the Participant would have been
     entitled to exercise the Option immediately prior to his death, such Option
     of the deceased Participant may be exercised within two years from the date
     of his death (but not later than the date on which the Option would
     otherwise expire) by the personal representatives of his estate or person
     or persons to whom his rights under such Option shall have passed by will
     or by laws of descent and distribution;

     (3)  Permanent and Total Disability (as such term is defined in Section
     22(e)(3) of the Code), then to the extent that the Participant would have
     been entitled to exercise the Option immediately prior to his Permanent and
     Total Disability, such Option may be exercised within one year from the
     date of such Permanent and Total Disability, but not later than the date on
     which the Option would otherwise expire.

Notwithstanding the provisions of any Option which provides for its exercise in
installments as designated by the Committee, such Option shall become
immediately exercisable upon the Participant's death or Permanent and Total
Disability.

     (d)  Effect of the Committee's Decisions.  The Committee's determination
whether a Participant's Continuous Service has ceased, and the effective date
thereof shall be final and conclusive on all persons affected thereby.

     9.   SARS (STOCK APPRECIATION RIGHTS)

     (a)  Granting of SARS.  In its sole discretion, the Committee may from time
to time grant SARs to Employees either in conjunction with, or independently of,
any Options granted under the Plan.  An SAR granted in conjunction with an
Option may be an alternative right wherein the exercise of the Option terminates
the SAR to the extent of the number of shares purchased upon exercise of the
Option and, correspondingly, the exercise of the SAR terminates the Option to
the extent of the number of Shares with respect to which the SAR is exercised.
Alternatively, an SAR granted in conjunction with an Option may be an additional
right wherein both the SAR and the Option may be exercised.  An SAR may not be
granted in conjunction with an ISO under circumstances in which the exercise of
the SAR affects the right to exercise the ISO or vice versa, unless the SAR, by
its terms, meets all of the following requirements:

     (1)  The SAR will expire no later than the ISO;

     (2)  The SAR may be for no more than the difference between the Exercise
     Price of the ISO and the Market Value of the Shares subject to the ISO at
     the time the SAR is exercised;

     (3)  The SAR is transferable only when the ISO is transferable, and under
     the same conditions;

     (4)  The SAR may be exercised only when the ISO may be exercised; and

     (5)  The SAR may be exercised only when the Market Value of the Shares
     subject to the ISO exceeds the Exercise Price of the ISO.

                                       5
<PAGE>
 
     (b)  Exercise Price. The Exercise Price as to any particular SAR shall not
be less than the Market Value of the Optioned Shares on the date of grant.

     (c)  Timing of Exercise.  Any election by a Participant to exercise SARs
shall be made during the period beginning on the 3rd business day following the
release for publication of quarterly or annual financial information and ending
on the 12th business day following such date.  This condition shall be deemed to
be satisfied when the specified financial data is first made publicly available.
In no event, however, may an SAR be exercised within the six-month period
following the date of its grant.

     The provisions of Paragraph 8(c) regarding the period of exercisability of
Options is incorporated by reference herein, and shall determine the period of
exercisability of SARS.

     (d)  Exercise of SARS. An SAR granted hereunder shall be exercisable at
such times and under such conditions as shall be permissible under the terms of
the Plan and of the Agreement granted to a Participant, provided that an SAR may
not be exercised for a fractional Share. Upon exercise of an SAR, the
Participant shall be entitled to receive, without payment to the Bank except for
applicable withholding taxes, an amount equal to the excess of (or, in the
discretion of the Committee if provided in the Agreement, a portion of) the
excess of the then aggregate Market Value of the number of Optioned Shares with
respect to which the Participant exercises the SAR, over the aggregate Exercise
Price of such number of Optioned Shares. This amount shall be payable by the
Bank in cash.

     (e)  Procedure for Exercising SARS.  To the extent not inconsistent
herewith, the provisions of Paragraph 8(b) as to the procedure for exercising
Options are incorporated by reference, and shall determine the procedure for
exercising SARS.

     10.  CHANGE IN CONTROL

     (a)  General Rule.  Notwithstanding the provisions of any Award which
provides for its exercise or vesting in installments, upon the date of a Change
in Control or an offer to effect a Change in Control, (i) all Options and SARs
shall become immediately exercisable and fully vested, and (ii) the Participant
shall, at the discretion of the Committee, be entitled to receive cash in an
amount equal to the excess of the Market Value of the Common Stock subject to
such Option over the Exercise Price of such Shares, in exchange for the
cancellation of such Options by the Participant.

     (b)  Exception to General Rule.  Notwithstanding subparagraph (A) of this
Paragraph, in no event may an SAR be exercised, or an Option be canceled in
exchange for cash, within the six-month period following the date of its grant.

     11.  EFFECT OF CHANGES IN COMMON STOCK SUBJECT TO THE PLAN.

     (a)  Recapitalizations; Stock Splits, Etc.  The number and kind of shares
reserved for issuance under the Plan, and the number and kind of shares subject
to outstanding Awards (and the Exercise Price thereof in the case of Options and
SARS), shall be proportionately adjusted for any increase, decrease, change or
exchange of Shares for a different number or kind of shares or other securities
of the Bank which results from a merger, consolidation, recapitalization,
reorganization, reclassification, stock dividend, split-up, combination of
shares, or similar event in which the number or kind of shares is changed
without the receipt or payment of consideration by the Bank.

                                       6
<PAGE>
 
     (b)  Transactions in which the Bank is Not the Surviving Entity. Subject to
Paragraph 10 hereof, in the event of (i) the liquidation or dissolution of the
Bank, (ii) a merger or consolidation in which the Bank is not the surviving
entity, or (iii) the sale or disposition of all or substantially all of the
Bank's assets (any of the foregoing to be referred to herein as a
"Transaction"), all outstanding Awards shall be surrendered. With respect to
each Award so surrendered the Committee shall in its sole and absolute
discretion determine whether the holder of the surrendered Award shall 
receive --

     (1)  for each Share then subject to an outstanding Award the number and
     kind of shares into which each outstanding Share (other than Shares held by
     dissenting stockholders) is changed or exchanged, together with an
     appropriate adjustment to the Exercise Price; or

     (2)  a cash payment (from the Bank or the successor corporation) in an
     amount equal to the Market Value of the Shares subject to the Award on the
     date of the Transaction, less the Exercise Price of the Award.

     (c)  Special Rule for ISOS. Any adjustment made pursuant to subparagraphs
(a) or (b)(1) hereof shall be made in such a manner as not to constitute a
modification, within the meaning of Section 424(h) of the Code, of outstanding
ISOs.

     (d)  Conditions and Restrictions on New, Additional, or Different Shares or
Securities. If, by reason of any adjustment made pursuant to this Paragraph, a
Participant becomes entitled to new, additional, or different shares of stock or
securities, such new, additional, or different shares of stock or securities
shall thereupon be subject to all of the conditions and restrictions which were
applicable to the Shares pursuant to the Award before the adjustment was made.

     (e)  Other Issuances. Except as expressly provided in this Paragraph, the
issuance by the Bank or an Affiliate of shares of stock of any class, or of
securities convertible into Shares or stock of another class, for cash or
property or for labor or services either upon direct sale or upon the exercise
of rights or warrants to subscribe therefor, shall not affect, and no adjustment
shall be made with respect to, the number, class, or Exercise Price of Shares
then subject to Awards or reserved for issuance under the Plan.

     12.  NON-TRANSFERABILITY OF AWARDS.

     Awards may not be sold, pledged, assigned, hypothecated, transferred or
disposed of in any manner other than by will or by the laws of descent and
distribution, or pursuant to the terms of a "qualified domestic relations order"
(within the meaning of Section 414(p) of the Code and the regulations and
rulings thereunder).

     13.  TIME OF GRANTING AWARDS.

     The date of grant of an Award shall, for all purposes, be the date on which
the Committee makes the determination of granting such Award.  Notice of the
determination shall be given to each Participant to whom an Award is so granted
within a reasonable time after the date of such grant.

     14.  EFFECTIVE DATE.

     The Plan shall become effective immediately upon its approval by the Board.
Awards may be made prior to approval of the Plan by the stockholders of the Bank
if the exercise of Awards in the form of Options and/or SARs is subject to such
stockholder approval.

                                       7
<PAGE>
 
     15.  APPROVAL BY STOCKHOLDERS.

     The Plan shall be approved by stockholders of the Bank within twelve (12)
months before or after the Effective Date.

     16.  MODIFICATION OF AWARDS.

     At any time, and from time to time, the Board may authorize the Committee
to direct execution of an instrument providing for the modification of any
outstanding Award, provided no such modification shall confer on the holder of
said Award any right or benefit which could not be conferred on him by the grant
of a new Award at such time, or impair the Award without the consent of the
holder of the Award.

     17.  AMENDMENT AND TERMINATION OF THE PLAN.

     The Board may from time to time amend the terms of the Plan and, with
respect to any Shares at the time not subject to Awards, suspend or terminate
the Plan, provided that any amendment that is "material" within the meaning of
Rule 16b-3 shall be subject to stockholder approval.

     No amendment, suspension or termination of the Plan shall, without the
consent of any affected holders of an Award, alter or impair any rights or
obligations under any Award theretofore granted.

     18.  CONDITIONS UPON ISSUANCE OF SHARES.

     (a)  Compliance with Securities Laws.  Shares of Common Stock shall not be
issued with respect to any Award unless the issuance and delivery of such Shares
shall comply with all relevant provisions of law, including, without limitation,
the Securities Act of 1933, as amended, the rules and regulations promulgated
thereunder, any applicable state securities law, and the requirements of any
stock exchange upon which the Shares may then be listed. The Plan is intended to
comply with Rule 16b-3, and any provision of the Plan which the Committee
determines in its sole and absolute discretion to be inconsistent with said Rule
shall, to the extent of such inconsistency, be inoperative and null and void,
and shall not affect the validity of the remaining provisions of the Plan.

     (b)  Special Circumstances. The inability of the Bank to obtain approval
from any regulatory body or authority deemed by the Bank's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder shall relieve
the Bank of any liability in respect of the non-issuance or sale of such Shares.
As a condition to the exercise of an Option or SAR, the Bank may require the
person exercising the Option or SAR to make such representations and warranties
as may be necessary to assure the availability of an exemption from the
registration requirements of federal or state securities law.

     (c)  Committee Discretion.  The Committee shall have the discretionary
authority to impose in Agreements such restrictions on Shares as it may deem
appropriate or desirable, including but not limited to the authority to impose a
right of first refusal or to establish repurchase rights or both of these
restrictions.

     19.  RESERVATION OF SHARES.

     The Bank, during the term of the Plan, will reserve and keep available A
number of Shares sufficient to satisfy the requirements of the Plan.

                                       8
<PAGE>
 
     20.  WITHHOLDING TAX.

     The Bank's obligation to deliver Shares upon exercise of Awards shall be
subject to the Participant's satisfaction of all applicable federal, state and
local income and employment tax withholding obligations.  The Committee, in its
discretion, may permit the Participant to satisfy the obligation, in whole or in
part, by irrevocably electing to have the Bank withhold Shares, or to deliver to
the Bank Shares that he already owns, having a value equal to the amount
required to be withheld.  The value of Shares to be withheld, or delivered to
the Bank, shall be based on the Market Value of the Shares on the date the
amount of tax to be withheld is to be determined.  As an alternative, the Bank
may retain, or sell without notice, a number of such Shares sufficient to cover
the amount required to be withheld.

     21.  NO EMPLOYMENT OR OTHER RIGHTS.

     In no event shall an Employee's eligibility to participate or participation
in the Plan create or be deemed to create any legal or equitable right of the
Employee, or any other party to continue service with the Bank or any Affiliate.
No Employee shall have a right to be granted an Award or, having received an
Award, the right to again be granted an Award.  However, an Employee who has
been granted an Award may, if otherwise eligible, be granted an additional Award
or Awards.

     22.  GOVERNING LAW.

     The Plan shall be governed by and construed in accordance with the laws of
the Commonwealth of Massachusetts, except to the extent that federal law shall
be deemed to apply.

                              BOARD OF DIRECTORS
                          SANDWICH CO-OPERATIVE BANK
                            SANDWICH, MASSACHUSETTS
                               NOVEMBER 15, 1983


                                 PRESENTED BY:
                                 GEORGE SYLVIA

                           DEFERRED INCOME AGREEMENT
                           -------------------------


    THE FOUNDATION OF THE PLAN IS AN AGREEMENT BETWEEN EACH DIRECTOR AND
SANDWICH CO-OPERATIVE BANK.

    THE THREE MAIN PROVISIONS OF THE AGREEMENT ARE AS FOLLOWS:

          1.   THE DIRECTOR AGREES TO SERVE ON THE BOARD FOR FIVE YEARS, IF
               ELECTED.

          2.   THE BANK WILL PAY THE DIRECTOR A FUTURE MONTHLY INCOME FOR TEN
               YEARS BEGINNING AT AGE 65. *

          3.   IN THE EVENT OF THE DIRECTOR'S PREMATURE DEATH, THE BANK WILL
               MAKE SPECIFIED MONTHLY PAYMENTS TO THE DIRECTOR'S
               BENEFICIARY(IES).

    EACH DIRECTOR'S AGREEMENT IS CONTAINED IN A LATER SECTION OF THIS BOOK, THE
AGREEMENTS CONFORM STRICTLY TO THE IRS DOCTRINES OF ECONOMIC BENEFIT AND
CONSTRUCTIVE RECEIPT TO ASSURE PROPER TAX TREATMENT.

*   The term or age may be different for each Director or see individual
    agreements.

                               FUNDING THE PLAN
                               ----------------


    THE BANK HAS ACQUIRED AN AMOUNT OF KEY MAN INSURANCE ON THE LIFE OF EACH
DIRECTOR CALCULATED TO MEET ITS OBLIGATIONS UNDER THE COMPENSATION AGREEMENT.
As OWNER OF THE POLICY, THE BANK IS THE NAMED BENEFICIARY AND THE CASH VALUE IS
AN UNRESTRICTED ASSET OF SANDWICH CO-OPERATIVE BANK.

    ANNUAL PREMIUMS WILL BE EQUAL TO THE DIRECTOR'S DEFERRAL SO THE BANK'S CASH
FLOW WILL NOT BE CHANGED DURING THE FIVE YEAR DE  FERRAL PERIOD.  AFTER THE
FIFTH YEAR, THE BANK WILL PAY ALL FUTURE PREMIUMS AND AFTER-TAX INTEREST COSTS
WITH A POLICY LOAN. THE CASH VALUE OF THE POLICY WILL ALWAYS BE LARGE ENOUGH TO
PROVIDE FOR THESE ANNUAL LOANS.  AS A RESULT, THE BANK HAS A ZERO NET OUTLAY
ANNUALLY AFTER THE FIFTH YEAR. (SEE EXHIBIT I ON PAGE 4.)

    ALL LOANS ARE MADE WITH THE AUTOMATIC LOAN PROVISION IN THE POLICY.
THEREFORE, THERE IS NO ADMINISTRATIVE PROCEDURE REQUIRED BY THE BANK.

                             INCOME TAX PROVISIONS
                             ---------------------

     TAX TREATMENT OF DEFERRED COMPENSATION HAS NEVER BEEN MORE FAVORABLE OR
STATED MORE CLEARLY THAN THAT PROVIDED BY THE REVENUE ACT OF 1978.

FOR SANDWICH CO-OPERATIVE BANK:
- ------------------------------ 

     1.   ANNUAL PREMIUM DEPOSITS ARE NOT TAX DEDUCTIBLE. (IRC SEC. 264 (A)
          (1).) THE CASH VALUE, OWNED BY THE BANK, IS AN OFFSETTING ASSET.
          UNDER THE PRECEPTS OF THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC
          ACCOUNTANTS, THE ACTUAL INSURANCE EXPENSE IS THE EXCESS OF THE ANNUAL
          PREMIUM PAID OVER THE ANNUAL INCREASE IN CASH VALUE.
     2.   DEFERRED INCOME PAID UNDER THE AGREEMENT IS FULLY TAX DEDUCTIBLE.
     3.   POLICY PROCEEDS RECEIVED BY THE BANK ARE TAX-FREE.

FOR YOUR DIRECTORS:
- ------------------ 

     1.   THE DIRECTOR HAS NO INCOME TAX LIABILITY UNTIL HE RECEIVES DEFERRED
          INCOME PAYMENTS.
     2.   DEFERRED INCOME PAYMENTS ARE TAXED AS ORDINARY INCOME.
     3.   WHEN HE RECEIVES THE DEFERRED INCOME, THE DIRECTOR MAY BE IN A LOWER
          TAX BRACKET.
     4.   ANY. INCOME, RECEIVED BY THE DIRECTOR"S FAMILY IS TAXED AS ORDINARY
          INCOME.

              ACCOUNTING FOR YOUR DIRECTORS' DEFERRED INCOME PLAN
              ---------------------------------------------------

     THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS HAS NOT ESTABLISHED
A STANDARD METHOD OF ACCOUNTING FOR DEFERRED IN  COME PLANS FINANCED WITH KEY
MAN LIFE INSURANCE.

     IT SEEMS CLEAR THAT THE KEY MAN INSURANCE AND THE DEFERRED COMPENSATION
OBLIGATION MUST BE ACCOUNTED FOR SEPARATELY. THE MOST WIDELY ACCEPTED VIEWS
APPEAR TO BE AS FOLLOWS:

     1.   Key Man Insurance is discussed in the Unofficial Accounting
          -----------------                                          
          Interpretations of the AICPA. it states, "The generally accepted
          method of accounting for non-term insurance on the life of a corporate
          officer (or director) is to charge the increase in the cash surrender
          value of the policy to an asset account and to charge the remaining
          balance of the annual premium to expense (or income)".

     2.   Deferred Income Agreements constitute a future obligation of the Bank.
          --------------------------                                            
          it this is considered to be a material amount, one method is to accrue
          a reserve equal to the present value of the payments at the time the
          payments are scheduled to commence.  If the amount is not considered
          to be material, the deferred payments are expensed as paid.

     YOUR ACCOUNTANT WILL BE ABLE TO RECOMMEND GOOD ACCOUNTING PRACTICE BEST
SUITED TO YOUR NEEDS.  BRICK AND COMPANY IS ALWAYS AVAILABLE TO MEET WITH YOUR
ACCOUNTANTS.

                             ACTUARIAL ASSUMPTIONS
                             ---------------------

     THIS DEFERRED INCOME PLAN HAS BEEN DEVELOPED IN ACCORDANCE WITH SOUND
ACTUARIAL PRINCIPLES.  THE FOLLOWING ASSUMPTIONS HAVE BEEN MADE:

     1.   EACH DIRECTOR WILL REACH NORMAL LIFE EXPECTANCY.

     2.   LIFE INSURANCE PREMIUMS WILL BE PAID THROUGHOUT THE DIRECTOR'S
          LIFETIME.  THE BANK HAS A ZERO NET OUTLAY ANNUALLY AFTER THE FIFTH
          YEAR BECAUSE PREMIUMS AND AFTER-TAX INTEREST COSTS ARE PAID WITH
          POLICY LOANS. (SEE EXHIBIT I ON PAGE FOUR.)

     3.   DEFERRED INCOME PAYMENTS, AS SPECIFIED IN THE AGREEMENT, WILL BE MADE
          BY THE BANK.

     4.   CURRENT DIVIDEND SCALES WILL BE MAINTAINED BY THE INSURANCE CARRIER.

     5.   THE BANK WILL BE REIMBURSED FOR THE USE OF ITS FUNDS AT THE RATE OF
          12% COMPOUNDED ANNUALLY (6% AFTER-TAX).

     6.   THE BANK'S MARGINAL INCOME TAX-BRACKET IS 30%.


     IF THESE ASSUMPTIONS ARE REALIZED, THE BANK WILL BE FULLY REIMBURSED FOR
ITS OUTLAY PLUS INTEREST AT THE RATE OF 12% COM  POUNDED ANNUALLY.  THE NET COST
TO THE BANK WILL BE THE SAME AS PAYING CURRENT CASH FEES.

                            SUMMARY AND CONCLUSION
                            ----------------------
                                        
     THE PURPOSE OF THIS PROGRAM IS TO PROVIDE A MORE ATTRACTIVE MEANS OF
COMPENSATION FOR SOME DIRECTORS OF SANDWICH CO-OPERATIVE BANK.


     THE BANK'S NET COST TO ADOPT THE PLAN IS DESIGNED TO BE THE SAME AS PAYING
CURRENT CASH FEES.  THIS PERMITS EACH BOARD MEMBER TO ELECT BETWEEN CURRENT AND
FUTURE INCOME.

     THE CASH VALUE OF EACH INSURANCE POLICY IS AN UNRESTRICTED ASSET OF THE
BANK, TO THE EXTENT THAT THE CASH VALUE EXCEEDS THE POLICY LOAN, THE BANK MAY
BORROW THIS EXCESS TO GENERATE INCOME FOR THE BANK.

     A DIRECTOR COULD NOT DUPLICATE THIS ECONOMIC BENEFIT WITH HIS OWN AFTER-TAX
DOLLARS. FOR THIS REASON, THE PROGRAM MAY BE FAR MORE VALUABLE TO HIM THAN CASH
FEES TAXED AT A HIGH RATE.

     FINALLY, IT IS IMPORTANT TO RECOGNIZE THAT AN IMMEDIATE ESTATE ASSET IS
CREATED FOR EACH DIRECTOR WHO PARTICIPATES. THERE IS NO OTHER MEANS OF PROVIDING
THIS BENEFIT AT A COMPARABLE LOW NET COST.

                          DEFERRED COMPENSATION PLAN
                          --------------------------

     THIS PLAN is dated as of the first day of                 , 19  , by
Sandwich Cooperative Bank, a Massachusetts Corporation, having its principal
place of business in Sandwich, Massachusetts (hereinafter the "Bank").

                                  WITNESSETH:

     WHEREAS, the Bank has a group of Directors who serve the Bank in a
Director's capacity;

     WHEREAS, the Bank wishes to adopt a non-qualified deferred compensation
plan in order to allow this select group of Directors to defer their fees as
herein provided;

     NOW, THEREFORE, the Bank hereby adopts the Sandwich Cooperative Bank
DEFERRED COMPENSATION PLAN (hereinafter the "Plan") effective as of January 1,
1992 as follows:

     1.   PLAN YEAR

     The initial Plan year shall commence on January 1, 1992 and shall end on
December 31, 1992, and thereafter shall be the twelve (12) month period
commencing on January 1 and ending. on December 31.

     2.   PARTICIPATION IN PLAN

          Any Eligible Director of the Bank who has complied with the provisions
of Section 6 herein shall be eligible to participate in the Plan. For the
purposes of the Plan, an Eligible Director means any Director of the Bank who
voluntarily participates in the Plan.

     3.   DEFERRED COMPENSATION

          Any Eligible Director may elect to become a Participant in the Plan in
accordance
<PAGE>
 
with Section 6 of the Plan by deferring up to one hundred percent (100%) of his
Eligible Compensation in whole percentages in any calendar year.  Such deferrals
shall hereinafter be referred to as "Deferred Compensation".  For the purposes
of this Plan, Eligible Compensation means the Eligible Director's fees paid or
accrued by the Bank.

          The amount of Eligible Compensation that a Participant elects to defer
is irrevocable for the Plan year for which such election is effective.

     4.   BANK CONTRIBUTIONS

          The Bank shall make no matching contribution of the Deferred
Compensation on behalf of each Participant under the Plan.

     5.   DEFERRED COMPENSATION ACCOUNTS

          (a)  Establishment of accounts

               The Bank shall record Deferred Compensation amounts made on
behalf of each Participant in a deferred compensation account; or, as a
bookkeeping entry, (hereinafter the "Account") for such Participant. The Bank
shall also credit to each Participant's Account a rate of return for each Plan
Year after the Plan Year in which his participation begins no less than simple
interest credited annually at the quarterly average rate on United States
Treasury Securities adjusted to a constant maturity of one year as published by
the Federal Reserve Board in Selected Interest Rates Publication H 15.

          (b)  Investment of Accounts

          Funds so credited to each Participant's Account, if any, may be kept
in cash or invested or reinvested in mutual funds, stocks, bonds, securities,
annuity contracts, life insurance, contracts or any other assets as the Bank may
select in its sole discretion.  The Bank, in its discretion, may engage
investment counsel, and may delegate to such counsel authority as it may deem
<PAGE>
 
appropriate with respect to the investment of such funds, if any.

     The rate of return attributable to a Participant's Account for each Plan
Year after the Plan Year in which his participation begins will in no event be
less than simple interest credited annually at the quarterly average rate on
United States Treasury Securities adjusted to a constant maturity of one year as
published by the Federal Reserve Board in Selected Interest Rates Publication H
15.

          (c)  Funding

          The Bank reserves the absolute right at its sole and exclusive
discretion to insure or otherwise provide for the obligations of the Bank
undertaken by this Plan or to refrain from same, and to determine the extent,
nature and method thereof, including the establishment of one or more trusts.
Should the Bank elect to insure this Plan, in whole or in part, through the
medium of insurance or annuities, or both, the Bank shall be the owner and
beneficiary of the policy.  At no time shall the Participant be deemed to have
any right, title or interest in or to any specified asset or assets of the Bank,
or any trust or escrow arrangement, including, but not by way of restriction,
any insurance or annuity or contracts or the proceeds therefrom.

     Any such policy, contract or asset shall not in any way be considered to be
security for the performance of the obligations of this Plan.

     If the Bank purchases a life insurance or annuity policy on the life of the
Participant, the Participant agrees to sign any papers that may be required for
that purpose and to undergo any medical examination or tests (at the Bank's
expense) which may be necessary, and generally cooperate with the Bank in
securing such policy.

     To the extent the Participant acquires a right to receive benefits under
this Plan, such right shall be no greater than the right of any unsecured
general creditor of the Bank.

is attributable to his Deferred Compensation and the earnings thereon.

     8    BENEFICIARY DESIGNATION

                         Participant or his beneficiary in accordance with
                         Section 14,

                         benefits under this Plan, or

                    (3)  the failure of the Bank to make any payment in

in whole or in part,
<PAGE>
 
the Bank shall provide a written notice of approval or denial within sixty (60)
days of the Bank's receipt of the notice of the claim. In the case of denial the
notice shall set forth the specific reason for the denial, specific reference to
the provisions of the Plan upon which the denial is based, and any additional
material or information necessary to perfect the claim and an explanation of why
such material or information is to be taken if a review of the denial is
desired. If the claim is not approved or denied within such sixty (60) days, the
claim will be deemed denied.

          (b) If a claim is denied and a review is desired, the Participant (or
his beneficiary in the case of the Participant's death), shall notify the Bank
of his request for a review in writing within sixty (60) days of the date the
claim is denied.  The Participant, his beneficiary, or his duly authorized
representative may review this Plan and any documents relating to it and submit
any written issues and comments he may feel appropriate within thirty (30) days
of his notice of request for review.  In its sole discretion, the Bank shall
then review the claim and any written issues and comments submitted by or on
behalf of the Participant, and provide a written decision within sixty (60) days
of the later of the Bank's receipt of the notice of request for review or the
submission of such written issues and comments.  This decision likewise shall
state the specific reasons for the decision and shall include reference to
specific provisions of this Plan on which the decision is based.

          (c) Any decision of the Bank shall not be binding on the Participant,
his personal representative, or any beneficiary without consent, nor shall it
preclude further action by the Participant, his personal representative or
beneficiary.

     THIS AGREEMENT, made and entered into this 5th day of May, 1995 by and

                                  WITNESSETH:

     WHEREAS, the Executive has been in the employ of the Corporation and/or its
subsidiaries and is now serving the Corporation as its Chief Executive Officer;
and,

     WHEREAS, because of the Executive's experience, knowledge of affairs of the

interest that the Executive's service be retained;

     WHEREAS, in order to induce the Executive to continue in the employ of the
Corporation and in recognition of his past service, the Board of Directors voted
on January 16, 1990 to authorize the Corporation to enter into an agreement
dated April 26, 1990 to provide him or his beneficiaries certain benefits; and,

1.01   EMPLOYMENT.  The Corporation may employ the Executive in such capacity
       ----------                                                   
as the Corporation may from time to time determine. Notwithstanding anything
contained herein, this Agreement is not an agreement of employment and nothing
herein shall restrict the Corporation concerning the terms and conditions of the
Executive's employment.

The benefits provided by this Agreement are not part of any salary reduction
plan or an arrangement deferring a bonus or a salary increase. The Executive has
no option to take any current payment or bonus in lieu of these salary
continuation benefits.

                                  ARTICLE TWO
                                  -----------

2.01   NORMAL RETIREMENT BENEFITS.
       -------------------------- 
(a)    If the Executive shall continue in the employment of the Corporation
       until the first of the month coincident with or next following his
       sixtieth birthday (hereinafter referred to as the "Normal Retirement
       Date"), he shall be entitled to a Normal Retirement Benefit, determined
       as of the effective date of his actual retirement and continuing for
       twenty (20) years, payable monthly, in the annual amount of sixty percent
       (60%) of his Benefit Computation Base (hereinafter defined), reduced by
       the sum of (1), (2) and (3) below.

       1.      Fifty percent (50%) of the Executive's (actual or projected)
               annual primary social security retirement benefit projected as of
               the Executive's social security normal retirement age based on
               his Benefit Computation Base in effect on the date of termination
               of the Executive's employment with the Corporation;

       2.      The annual amount of benefits payable to the Executive (or his
               beneficiaries) at the Normal Retirement Date calculated on a
               single life annuity basis from any qualified defined benefit
               pension plan maintained and funded by the

                                       2
<PAGE>
 
               Corporation, as such plan or plans may be amended or modified
               from time to time;

       3.      The annual amount of benefits payable at the Normal Retirement
               Date on a single life annuity basis attributable to the portion
               of the account balances of the Executive arising from employer
               contributions (but excluding the portion of such balances arising
               from employee salary reduction and elective contributions) at the
               date of determination, from the Corporation's Employee Stock
               Ownership Plan ("ESOP"), 401(k) and other defined contribution
               retirement plans maintained by the Corporation as of the date of
               this agreement, or their successors, as such plan or plans may be
               modified from time to time.

(b)    If the Executive has (or will have) completed fewer than twenty-five (25)
       years (or 300 months) of service with the Corporation as of his Normal
       Retirement Date, then the Normal Retirement Benefit shall be the amount
       determined by multiplying the amount which would otherwise be the Normal
       Retirement Benefit under paragraph (a) above, by a fraction, not to
       exceed one (1), the numerator of which is the actual number of months of
       the Executive's employment with the Corporation, and the denominator of
       which is three hundred (300) months.

2.02   BENEFIT COMPUTATION BASE.  The Executive's Benefit Computation Base
       ------------------------                                           
shall be the average of the Executive's annual base salary (including any salary
reduction amounts pursuant to Sections 401(k) or 125 of the Internal Revenue
Code of 1986, as amended) paid during the thirty-six (36) consecutive calendar
months during the Executive's period of employment by the Corporation in which
such compensation is the highest.

2.03   ACCRUED BENEFIT.  As used herein for the purposes of Section 3.01, 4.01,
       ---------------

<PAGE>
 
       1.      The benefit amount the Executive would be entitled to under
               Section 2. 0 1, commencing at the Executive's Normal Retirement
               Date except that in the event of (a) death, (b) disability, (c)
               termination of employment, (d) early retirement, or (e) merger,
               consolidation or sale (in the event of (d), as modified by
               Section 10.1 hereof as the case may be, the benefit to which the
               Executive will be entitled shall be determined by multiplying the
               Normal Retirement Benefit amount by a fraction, not to exceed one
               (1), the numerator of which is the actual number of months of the
               Executive's employment with the Corporation, and the denominator
               of which is three hundred (300) months.

       2.      If the Executive terminates employment prior to his Normal
               Retirement Date, in calculating his Accrued Benefit, (i) the
               offset for primary social security retirement benefit shall be
               calculated on the basis of the amount projected to be payable at
               the Executive's social security normal retirement age assuming
               continued earnings by the Executive at the rate in effect at
               termination of employment until the Executive's social security
               normal retirement age; (ii) the offset for any qualified defined
               benefit plan shall be calculated on the basis of the Executive's
               accrued benefit in said plan upon termination of employment
               projected to be payable at the Executive's Normal Retirement
               Date, and (iii) the offset for any benefits arising from employer
               contributions attributable to the account balances of the
               Executive arising from the Corporation's ESOP, 401(k) plan or any
               other defined contribution retirement plan shall also be
               calculated on the basis of the Executive's accrued benefit in
               such plan(s) upon termination of employment projected to be
               payable at the Executive's Normal Retirement Date.

payable under Section 4.01, 5.01 (5.02 or 10.01) of this Agreement, the

of payment may be a lump sum payment and any optional form of annuity payment
which is provided to the Executive under the terms of the Corporation's

(b)    If the Executive dies following the commencement of the payment of
       benefits under Section 2.01, 4.01, 5.01, 5.02, or 10.01, such payment of
       benefits shall continue to the named beneficiaries of the Executive until

benefit provided in this Section 5.01 prior to the Normal Retirement Date at any

Corporation's Qualified defined benefit pension plan for each month payment
commences prior to the Normal Retirement Date.

       ------- 

(a)    The Corporation reserves the right at its sole and exclusive discretion
       to insure or otherwise provide for the obligations of the Corporation
       undertaken by this Agreement or to refrain from same, and to determine
       the extent, nature and method thereof, including the establishment of one
       or more trusts. Should the Corporation elect to insure this Agreement, in
       whole or in part, through the medium of insurance or annuities, or both,
       the Corporation shall be the owner and beneficiary of the policy or
       annuity. At no time shall the Executive be deemed to have any right,
       title or interest in or to any specified asset or assets of the
       Corporation, or any trust or escrow arrangement, including, but not by
       way of restriction, any insurance or annuity contracts or the proceeds
       therefrom.

(b)    Any such policy, contract or asset shall not in any way be considered to
       be security for the performance of the obligations of this Agreement.

(c)    If the Corporation purchases a life insurance or annuity policy on the
       life of the Executive, the Executive agrees to sign any papers that may
       be required for that purpose and to undergo any medical examination or
       tests (at the Corporation's expense) which may be necessary, and
       generally cooperate with the Corporation in securing such policy.

(d)    To the extent the Executive acquires a right to receive benefits under
       this Agreement, such right shall be equivalent to the right of an
       unsecured general creditor of the Corporation.

other corporation being the survivor corporation, nor shall it sell
substantially all of its assets to another corporation, firm or person, unless
and until:

(a)    The Executive and such other corporation, firm or person agree that the
       Executive shall continue in the employ of the succeeding, continuing or
       acquiring corporation, firm or person and such other corporation, firm or
       person agrees in writing without further qualification to assume and
       discharge the obligations of the Corporation under this Agreement, or,

(b)    If the Executive and such corporation, firm or person do not agree that
       the Executive shall continue in the employ of such corporation, firm or
       person, or such corporation, firm or person does not so agree to assume
       and discharge such obligations, the Corporation shall pay to the
       Executive, in one lump sum, his Accrued Benefit as of the date of such
       merger, consolidation or sale. AR calculations of the Accrued Benefit for
       purposes of this Section 10.1(b), shall further be discounted to present
       value in accordance with the actuarial tables used in the Corporation's
       defined benefit pension plan.

                                  -----------

2.01   NORMAL RETIREMENT BENEFITS.
       -------------------------- 

(a)    If the Executive shall continue in the employment of the Corporation
       until the first of the month coincident with or next following his
       sixtieth birthday (hereinafter referred to as the "Normal Retirement
       Date"), he shall be entitled to a Normal Retirement Benefit, determined
       as of the effective date of his actual retirement and continuing for
       twenty (20) years, payable monthly, in the annual amount of sixty percent
       (60%) of his Benefit Computation Base (hereinafter defined), reduced by
       the sum of (1), (2) and (3) below.

       1.      Fifty percent (50%) of the Executive's (actual or projected)
               annual primary social security retirement benefit projected as of
               the Executive's social security normal retirement age based on
               his Benefit Computation Base in effect on the date of termination
               of the Executive's employment with the Corporation;

       2.      The annual amount of benefits payable to the Executive (or his
               beneficiaries) at the Normal Retirement Date calculated on a
               single life annuity basis from any qualified defined benefit
               pension plan maintained and funded by the

<PAGE>
 
               Corporation, as such plan or plans may be amended or modified
               from time to time;

       3.      The annual amount of benefits payable at the Normal Retirement
               Date on a single life annuity basis attributable to the portion
               of the account balances of the Executive arising from employer
               contributions (but excluding the portion of such balances arising
               from employee salary reduction and elective contributions) at the
               date of determination, from the Corporation's Employee Stock
               Ownership Plan ("ESOP"), 401(k) and other defined contribution
               retirement plans maintained by the Corporation as of the date of
               this agreement, or their successors, as such plan or plans may be
               modified from time to time.

(b)    If the Executive has (or will have) completed fewer than twenty-five (25)
       years (or 300 months) of service with the Corporation as of his Normal
       Retirement Date, then the Normal Retirement Benefit shall be the amount
       determined by multiplying the amount which would otherwise be the Normal
       Retirement Benefit under paragraph (a) above, by a fraction, not to
       exceed one (1), the numerator of which is the actual number of months of
       the Executive's employment with the Corporation, and the denominator of
       which is three hundred (300) months.

2.02   BENEFIT COMPUTATION BASE.  The Executive's Benefit Computation Base
       ------------------------                                           
shall be the average of the Executive's annual base salary (including any salary
reduction amounts pursuant to Sections 401(k) or 125 of the Internal Revenue
Code of 1986, as amended) paid during the thirty-six (36) consecutive calendar
months during the Executive's period of employment by the Corporation in which
such compensation is the highest.

2.03   ACCRUED BENEFIT.  As used herein for the purposes of Section 3.01, 4.01,
       ---------------                                                   
5.01, or 5.02, the term "Accrued Benefit" shall mean:

     early retirement, or (e) merger, consolidation or sale (in the event of
     (d), as modified by Section 10.1 hereof as the case may be, the benefit to
     which the Executive will be entitled shall be determined by multiplying the
     Normal Retirement Benefit amount by a fraction, not to exceed one (1), the
     numerator of which is the actual number of months of the Executive's
     employment with the Corporation, and the denominator of which is three
     hundred (300) months.

2.   If the Executive terminates employment prior to his Normal Retirement Date,
     in calculating his Accrued Benefit, (i) the offset for primary social
     security retirement benefit shall be calculated on the basis of the amount
     projected to be payable at the Executive's social security normal
     retirement age assuming continued earnings by the Executive at the rate in
     effect at termination of employment until the Executive's social security
     normal retirement age; (ii) the offset for any qualified defined benefit
     plan shall be calculated on the basis of the Executive's accrued benefit in
     said plan upon termination of employment projected to be payable at the
     Executive's Normal Retirement Date, and (iii) the offset for any benefits
     arising from employer contributions attributable to the account balances of
     the Executive arising from the Corporation's ESOP, 401(k) plan or any other
     defined contribution retirement plan shall also be calculated on the basis
     of the Executive's accrued benefit in such plan(s) upon termination of
     employment projected to be payable at the Executive's Normal Retirement
     Date.

     1.01  EMPLOYMENT.  The Corporation may employ the Executive in such

     2.01  NORMAL RETIREMENT BENEFITS.
           -------------------------- 
     (a)   If the Executive shall continue in the employment of the Corporation
           until the first of the month coincident with or next following his
           sixtieth birthday (hereinafter referred to as the "Normal Retirement
           Date"), he shall be entitled to a Normal Retirement Benefit,
           determined as of the effective date of his actual retirement and
           continuing for twenty (20) years, payable monthly, in the annual
           amount of sixty percent (60%) of his Benefit Computation Base
           (hereinafter defined), reduced by the sum of (1), (2) and (3) below.

          1.   Fifty percent (50%) of the Executive's (actual or projected)
               annual primary social security retirement benefit projected as of
               the Executive's social security normal retirement age based on
               his Benefit Computation Base in effect on the date of termination
               of the Executive's employment with the Corporation;

          2.   The annual amount of benefits payable to the Executive (or his
               beneficiaries) at the Normal Retirement Date calculated on a
               single life annuity basis from any qualified defined benefit
               pension plan maintained and funded by the

                                       2

               Corporation, as such plan or plans may be amended or modified
               from time to time;

          3.   The annual amount of benefits payable at the Normal Retirement
               Date on a single life annuity basis attributable to the portion
               of the account balances of the Executive arising from employer
               contributions (but excluding the portion of such balances arising
               from employee salary reduction and elective contributions) at the
               date of determination, from the Corporation's Employee Stock
               Ownership Plan ("ESOP"), 401(k) and other defined contribution
               retirement plans maintained by the Corporation as of the date of
               this agreement, or their successors, as such plan or plans may be
               modified from time to time.

     (b)   If the Executive has (or will have) completed fewer than twenty-five
           (25) years (or 300 months) of service with the Corporation as of his
           Normal Retirement Date, then the Normal Retirement Benefit shall be
           the amount determined by multiplying the amount which would otherwise
           be the Normal Retirement Benefit under paragraph (a) above, by a
           fraction, not to exceed one (1), the numerator of which is the actual
           number of months of the Executive's employment with the Corporation,
           and the denominator of which is three hundred (300) months.

     2.02  BENEFIT COMPUTATION BASE.  The Executive's Benefit Computation Base
           ------------------------                                           
     shall be the average of the Executive's annual base salary (including any
     salary reduction amounts pursuant to Sections 401(k) or 125 of the Internal
     Revenue Code of 1986, as amended) paid during the thirty-six (36)
     consecutive calendar months during the Executive's period of employment by
     the Corporation in which such compensation is the highest.

     2.03  ACCRUED BENEFIT.  As used herein for the purposes of Section 3.01,
           ---------------

          1.   The benefit amount the Executive would be entitled to under
               Section 2.01, commencing at the Executive's Normal Retirement
               Date except that in the event of (a) death, (b) disability, (c)
               termination of employment, (d) early retirement, or (e) merger,
               consolidation or sale (in the event of (d), as modified by
               Section 10.1 hereof as the case may be, the benefit to which the
               Executive will be entitled shall be determined by multiplying the
               Normal Retirement Benefit amount by a fraction, not to exceed one
               (1), the numerator of which is the actual number of months of the
               Executive's employment with the Corporation, and the denominator
               of which is three hundred (300) months.

          2.   If the Executive terminates employment prior to his Normal
               Retirement Date, in calculating his Accrued Benefit, (i) the
               offset for primary social security retirement benefit shall be
               calculated on the basis of the amount projected to be payable at
               the Executive's social security normal retirement age assuming
               continued earnings by the Executive at the rate in effect at
               termination of employment until the Executive's social security
               normal retirement age; (ii) the offset for any qualified defined
               benefit plan shall be calculated on the basis of the Executive's
               accrued benefit in said plan upon termination of employment
               projected to be payable at the Executive's Normal Retirement
               Date, and (iii) the offset for any benefits arising from employer
               contributions attributable to the account balances of the
               Executive arising from the Corporation's ESOP, 401(k) plan or any
               other defined contribution retirement plan shall also be
               calculated on the basis of the Executive's accrued benefit in
               such plan(s) upon termination of employment projected to be
               payable at the Executive's Normal Retirement Date.

     9.01  FUNDING.
           ------- 
     (a)   The Corporation reserves the right at its sole and exclusive
           discretion to insure or otherwise provide for the obligations of the
           Corporation undertaken by this Agreement or to refrain from same, and
           to determine the extent, nature and method thereof, including the
           establishment of one or more trusts. Should the Corporation elect to
           insure this Agreement, in whole or in part, through the medium of
           insurance or annuities, or both, the Corporation shall be the owner
           and beneficiary of the policy or annuity. At no time shall the
           Executive be deemed to have any right, title or interest in or to any
           specified asset or assets of the Corporation, or any trust or escrow
           arrangement, including, but not by way of restriction, any insurance
           or annuity contracts or the proceeds therefrom.

     (b)   Any such policy, contract or asset shall not in any way be considered
           to be security for the performance of the obligations of this
           Agreement.

     (c)   If the Corporation purchases a life insurance or annuity policy on
           the life of the Executive, the Executive agrees to sign any papers
           that may be required for that purpose and to undergo any medical
           examination or tests (at the Corporation's expense) which may be
           necessary, and generally cooperate with the Corporation in securing
           such policy.

     (d)   To the extent the Executive acquires a right to receive benefits
           under this Agreement, such right shall be equivalent to the right of
           an unsecured general creditor of the Corporation.

     (a)   The Executive and such other corporation, firm or person agree that
           the Executive shall continue in the employ of the succeeding,
           continuing or acquiring corporation, firm or person and such other
           corporation, firm or person agrees in writing without further
           qualification to assume and discharge the obligations of the
           Corporation under this Agreement, or,

     (b)   If the Executive and such corporation, firm or person do not agree
           that the Executive shall continue in the employ of such corporation,
           firm or person, or such corporation, firm or person does not so agree
           to assume and discharge such obligations, the Corporation shall pay
           to the Executive, in one lump sum, his Accrued Benefit as of the date
           of such merger, consolidation or sale. AR calculations of the Accrued
           Benefit for purposes of this Section 10.1(b), shall further be
           discounted to present value in accordance with the actuarial tables
           used in the Corporation's defined benefit pension plan.

     (a)    If the Executive shall continue in the employment of the Corporation
            until the first of the month coincident with or next following his
            sixtieth birthday (hereinafter referred to as the "Normal Retirement
            Date"), he shall be entitled to a Normal Retirement Benefit,
            determined as of the effective date of his actual retirement and
            continuing for twenty (20) years, payable monthly, in the annual
            amount of sixty percent (60%) of his Benefit Computation Base
            (hereinafter defined), reduced by the sum of (1), (2) and (3) below.
     
            1.  Fifty percent (50%) of the Executive's (actual or projected)
                annual primary social security retirement benefit projected as
                of the Executive's social security normal retirement age based
                on his Benefit Computation Base in effect on the date of
                termination of the Executive's employment with the Corporation;

            2.  The annual amount of benefits payable to the Executive (or his
                beneficiaries) at the Normal Retirement Date calculated on a
                single life annuity basis from any qualified defined benefit
                pension plan maintained and funded by the

          Corporation, as such plan or plans may be amended or modified from
          time to time;

      3.  The annual amount of benefits payable at the Normal Retirement Date on
          a single life annuity basis attributable to the portion of the account
          balances of the Executive arising from employer contributions (but
          excluding the portion of such balances arising from employee salary
          reduction and elective contributions) at the date of determination,
          from the Corporation's Employee Stock Ownership Plan ("ESOP"), 401(k)
          and other defined contribution retirement plans maintained by the
          Corporation as of the date of this agreement, or their successors, as
          such plan or plans may be modified from time to time.
     
(b)   If the Executive has (or will have) completed fewer than twenty-five (25)
      years (or 300 months) of service with the Corporation as of his Normal

          (in the event of (d), as modified by Section 10. 1 hereof as the case
          may be, the benefit to which the Executive will be entitled shall be
          determined by multiplying the Normal Retirement Benefit amount by a
          fraction, not to exceed one (1), the numerator of which is the actual
          number of months of the Executive's employment with the Corporation,
          and the denominator of which is three hundred (300) months.

          Date, in calculating his Accrued Benefit, (i) the offset for primary
          social security retirement benefit shall be calculated on the basis of
          the amount projected to be payable at the Executive's social security
          normal retirement age assuming continued earnings by the Executive at
          the rate in effect at termination of employment until the Executive's
          social security normal retirement age; (ii) the offset for any
          qualified defined benefit plan shall be calculated on the basis of the
          Executive's accrued benefit in said plan upon termination of
          employment projected to be payable at the Executive's Normal
          Retirement Date, and (iii) the offset for any benefits arising from
          employer contributions attributable to the account balances of the
          Executive arising from the Corporation's ESOP, 401(k) plan or any
          other defined contribution retirement plan shall also be calculated on
          the basis of the Executive's accrued benefit in such plan(s) upon
          termination of employment projected to be payable at the Executive's
          Normal Retirement Date.

                                  ----------

     Subject to the terms of the Plan, the Committee may, but shall not be
obligated to, from time to time grant MIP Awards to key Employees.  Any MIP
Awards that the Committee may grant to key Employees shall be subject to the
following terms and conditions, and to such other terms and conditions as are
prescribed by the Committee in the applicable Agreement.

     (a) Nature of MIP Awards.  Each MIP Award shall be made in the form of a
designated number of Units that shall be redeemed by the Bank, in exchange for
cash, at such times and under such conditions as shall be permissible under the
terms of the Plan and of the Agreement provided to the Participant.

                                      -3-
<PAGE>
 
     (b) Aggregate Limit. Except as otherwise required by the provisions of
Paragraph (f) hereof, the aggregate number of Units that may be subject to MIP
Awards shall be 90,000 Units. If Units subject to an MIP Award should expire or
be forfeited for any reason without having been redeemed, said Units shall,
unless the Plan shall have been terminated, be available for the grant of
additional MIP Awards under the Plan.

     (c) Vesting.  The Committee may, in its discretion, impose vesting
conditions on a Participant's right to receive cash upon the redemption of
Units, including, but not limited to, requirements of continuous employment for
a specified term, or the attainment of specific corporate, divisional or
individual performance standards or goals, which conditions may differ with
respect to each Participant.  The Agreement shall provide for forfeiture of the
right to redeem Units if the specified conditions are not met during the
specified vesting period.

     (d) Redemption of Units.  In each Agreement effecting an MIP Award, the
Committee shall identify a future date or dates of redemption for the Units
subject to the MIP Award, with said date or dates of redemption being either (I)
fixed by reference to a specific date or dates at least six months after the
date of the MIP Award, or (ii) a date or dates incident to the employee's
termination of employment for any reason, or for particular reasons such as
death or retirement at or after a specified age, or (iii) the earlier or later
to occur of a combination of dates described in (I) or (ii) hereof.  Within 10
business days following each redemption date, the Bank shall pay to the
Participant, without payment of any consideration to the Bank, an amount in cash
equal to the excess of --

     (x)  the Book Value, on the date of redemption, of a number of Shares equal
          to the number of Units which are being redeemed and as to which the
          Participant has a vested interest, over

     (y)  the Book Value of such Units on the date of the MIP Award.

     The amount payable to the Participant hereunder shall be subject to
reduction for applicable federal withholding taxes.

     (e) Term of MIP Awards; Effect of Termination of Employment. Unless the
Committee provides f or a shorter term pursuant to an Agreement, a Participant's
MIP Award shall automatically expire, and thereupon cease to be subject to
future redemption, on the earlier to occur of (I) the close of the 6th year
following the date of the MIP Award, and (ii) the date on which the
Participant's

                                      -4-
<PAGE>
 
employment terminates. Notwithstanding the foregoing, if a Participant's
employment terminates by reason of his death, disability, or retirement at or
after age 60, then, to the extent that the Participant had earned a vested
interest in his MIP Award immediately prior to such death, disability, or
retirement, as the case may be, any outstanding Units subject to the
Participant's MIP Award shall be redeemed for cash, with such payment being made
as soon as administratively practicable. For purposes hereof, the date of an MIP
Award to a Participant shall be the date on which the Committee provides the
Participant with an executed Agreement effecting the MIP Award.

     (f) Effect of Changes in Common Stock Subject to the Plan. The number of
Units reserved for award under the Plan, and the number of Units subject to
outstanding MIP Awards, shall be proportionately adjusted for any increase,
decrease, change or exchange of Shares for a different number or kind of shares
or other securities of the Bank which results from a merger, consolidation,
recapitalization, reorganization, reclassification, stock dividend, split-up,
combination of shares, or similar event in which the number of Shares is changed
without the receipt or payment of consideration by the Bank.

     Subject to Paragraph (g) hereof, in the event of (I) the liquidation or
dissolution of the Bank, (ii) a merger or consolidation in which the Bank is not
the surviving entity, or (iii) the sale or disposition of all or substantially
all of the Bank's assets (any of the foregoing to be referred to herein as a
"Transaction") , all outstanding Units shall be redeemed in exchange for cash in
an amount determined in accordance with Paragraph (d) hereof.

     (g) Effect of a Change in Control.  Notwithstanding the provisions of any
MIP Award that provides for its vesting in installments or over a future period,
all outstanding Units shall become fully vested upon a Change in Control, and
shall thereupon be redeemed in exchange f or a cash payment by the Bank in an
amount determined in accordance with Paragraph (d) hereof.

                              Source of Payments
                              ------------------

     The Bank's obligation to make cash payments pursuant to the Plan shall
constitute an unfunded, unsecured promise by the Bank to provide such payments,
as and to the extent such payments become due.  Payments shall be made from the
general assets of the Bank, and no person shall, by virtue of this Plan, have
any interest in such assets (other than as an unsecured creditor of the Bank).

                                  ----------

     Except as otherwise is provided by this Plan, it is agreed that neither the
Participant nor his Beneficiary nor any other person or persons shall have any
right to sell, assign, transfer, encumber and pledge or otherwise convey any MIP
Award, which MIP Awards are expressly declared to be nonassignable and
nontransferable.


                                  ARTICLE VII
                           No Retention of Services
                           ------------------------

     This Plan shall not be deemed to constitute a contract of employment
between the Bank and any Participant, and no Employee or Participant shall have
a right to be granted an MIP Award or, having received such a grant, the right
to again be granted an MIP Award.


                                 ARTICLE VIII
               Amendment and Termination; modification of Awards
               -------------------------------------------------

     The Board may amend or terminate the Plan at any time, provided that no
such amendment or termination shall, without the written consent of an affected
Participant, alter or impair any rights of the Participant under the Plan.

     At any time, and from time to time, the Board may authorize the Committee
to direct execution of an instrument providing for the modification of any
outstanding MIP Award, provided that no such modification shall confer on the
holder of said MIP Award any right or benefit which could not be conferred on
him by the grant of a new MIP Award at such time, or impair an MIP Award without
the consent of the holder of the MIP Award.


                                  ARTICLE IX
                                   State Law
                                   ---------

     This Plan shall be construed and governed in all respects under and by the
laws of the Commonwealth of Massachusetts, to the extent not preempted by
federal law.  If any provision of this Plan shall be held by a court of
competent jurisdiction to be invalid or unenforceable, the remaining provisions
hereof shall continue to be fully effective.

                                   ARTICLE X

     Heading and subheadings in this Plan are inserted for convenience and
reference only and constitute no part of this Plan.

                         THE SANDWICH CO-OPERATIVE BANK
                     MANAGEMENT INCENTIVE COMPENSATION PLAN
                                 December 1989

The objective of the Management Incentive Compensation Plan I-s to provide a
reasonable and effective means of recognizing, rewarding and encouraging
outstanding achievement on the part of management as a whole and the individual
officers of the Sandwich Co-operative Bank.

The principal measure of achievement utilized by the Plan focuses on corporate
performance - both short - and long-term - and the relationship of the
individual officers' performance to that of the Bank.  It is a fundamental
expectation of the Plan that +.-he performance objectives of its management
will, at all times, give principal consideration to the provision of share
holder value. Short-term gains which in any way compromise this requisite value,
the Bank's operating philosophy or understanding of purpose should be seen as
contrary to its interests and unworthy of consideration within the context of
the Management Incentive Compensation Plan.

The Management Incentive Compensation Plan is based on the following precepts:

A.   Overall corporate performance cannot be fully appreciated without a
     thorough understanding of corporate purpose and explicit definition of
     long-range objectives.  Once formulated, this understanding, in the form of
     a corporate plan, should be subject to ratification by the Directors and
     reviewed annually for purposes of modification and reratification.
<PAGE>
 
                                                                               2

B.   Under almost all circumstances, tire most accessible and consistently
     reliable yardstick for the measurement of corporate performance is
     profitability.  In this regard "Return on Assets" and "Return on Equity"
     will provide objective means of assessing profitability.

C.   Other measures of corporate performance may also be suitable, depending
     upon the circumstances and needs of the organization.  In the instance of
     the Sandwich Co-operative Bank, Asset Growth, Operating Expense, and Asset
     Quality will constitute reasonable additional measurement criteria for the
     assessment of organizational and senior management performance.  Interest
     rate spread, earnings per employee and deposit growth will provide
     reasonable measurement criteria for the assessment of the remaining
     management group.

D.   Eligibility for participation in the Plan should be limited to those who
     may be in a position to significantly contribute to the Bank's
     profitability, e.g., its officers and designated managers. (This
     delineation will serve as an incentive for nonparticipants to aspire to and
     achieve participant status.) It should be clearly understood, however, that
     eligibility alone does not assure an officer actual participation in any
     incentive compensation distribution.

E.   Actual distribution of incentive compensation should bear a direct
     relationship to individual performance and contribution to profitability.
                                                ----------------------------- 

          i.    Those who contribute little or nothing should be rewarded with
                little or nothing.
<PAGE>
 
                                                                               3

          ii.  Extraordinary contributions should be rewarded in an
     extraordinary fashion.  The effort, skill, risk and/or personal sacrifice
     required to produce superlative achievement cannot be effectively rewarded
     with token incentive awards.  Therefore, the higher the financial
     performance of the Bank and its officers, the greater the potential
     rewards.

          iii. Definition of both i and ii requires a mutual understanding
     relative to expected performance goals.  Individual performance goals
     should be explicitly defined at the beginning of each year, reviewed
     quarterly (for progress and/or need for modification) and used as a means
     of assessing performance at year-end.  The relative importance of various
     goals, as well as major unforseen changes in operating conditions must be
     considered in the final evaluation of performance levels.

          iv.  The magnitude of individual incentive compensation awards should
     be determined by the Chief Executive Officer, with the benefit of
     supporting assessment information provided in writing by senior  officers
     relative to their subordinates.

          v.   Incentive awards should be subject to ratification by the Salary
     Committee of the Board of Directors -which will, in addition, determine the
     Incentive Compensation award of the Chief Executive Officer.
<PAGE>
 
                                                                               4

     F. Particular effort will be required to ensure the relevancy of the
     incentive compensation awards, i.e., the sensitivity of the plan in
     recognizing and responding to variations in performance over time, and in
     relation to the expectations as well as the performance of members of the
     management group.  If distribution becomes unvarying, nondiscriminatory, or
     taken for granted, then the Plan's purpose will have been compromised.

     G. No incentive compensation plan is without flaw, nor immune to ultimate
     obsolescence.  For this reason, the Plan, its purpose and actual impact
     should be reassessed annually, and modifications adopted where necessary.
     It should be expected that the Plan will be substantially modified at the
     end of three years.

                       Procedures and Bonus Determination
                       ----------------------------------


The Management incentive Compensation Plan will be carried out in accordance
with the following procedure:

     1.   Senior management will formulate a Corporate Plan for the Bank -
          stating its understanding of purpose, operating philosophy, and
          general objectives. The Corporate Plan will be presented to the Board
          for review and ratification.

     2.   Eligibility of those to be included in the Plan will be recommended
          annually by the Chief Executive Officer to the Personnel Committee
          based on level of responsibility in the corporation. Any new employee
          occupying a level which would qualify for plan participation as
          determined by the Chief Executive Officer will be eligible for
          participation in their first year as designated in the Bonus Plan
          Contingency section on Page 9.

     3.   The Board of Directors will establish a Corporation Performance Review
          Committee which will consist of the members of the Finance and
          Personnel Committees.

     4.   Incentive Compensation will be based on both the financial performance
          of the corporation and individual performance:

                                                                               6

          a.   The Performance Review Committee will be charged with assessing
               overall Bank financial performance on an ongoing basis in
               conformance with the Corporation Plan. An analysis of peer group
               data will also be used in assessing the financial performance of
               the Bank where appropriate.

          b.   An objectives system will be established whereby each
               participating officer annually formulates, in conjunction with
               his or her direct superior, explicitly defined objectives for the
               year ahead.

     5.   At the close of each fiscal year, a determination of both Bank and
          individual performance will be made, subject to review and
          confirmation by the appropriate Bank officers and committees.

     6.   A bank performance based "incentive bonus pool" will be established as
          a percent of eligible plan participants' total salaries. Distributions
          from the pool will be made pro rata on the basis of the individual's
          salary level and performance against established objectives.

          a.   The financial performance criteria which will determine the
               amount of the senior management incentive bonus pool are
                             -----------------
               Profitability; Return on Assets; Return on Equity; Asset Growth;
               -------------------------------  ----------------  ------------
               Operating Expense; and, Asset Quality. The criteria used for
               -----------------       ------------- 
               determining the management incentive bonus pool are: Interest
                                                                    -------- 
               Rate Spread; Earnings per Employee; 
               -----------  ---------------------

               and, Deposit Growth (see pp. 12 - 19). The criteria ranges were
                    --------------
               determined based on peer group comparisons and an analysis of the
               Bank's historic, current and projected financial performance. It
               is recommended that the criteria ranges be adjusted every two or
               three years to accommodate changes in operating and economic
               conditions.

          b.   The individual plan participant's percent share of the "incentive
               bonus pool" will be determined by calculating his or her
               performance weighted pro rata share of total participant
               salaries.

                             HYPOTHETICAL EXAMPLE
                             --------------------

*    The total salaries of all plan participants is $400,000.

*    The Bank's results against plan criteria warrant an Incentive Bonus Pool of
         ------                                                                 
     10.0% - resulting in an Incentive Bonus Pool of $40,000 ($400,000 x 10% =
     $40,000).

*    Participant X was paid a base salary of $40,000 during the plan year.  His
     pro forma share of total salaries was 10.0%.

*    Participant X's performance "exceeded" his objectives established at the
     beginning of the year - resulting in a performance multiplier of 1.5 (see
     page 20).  His "gross performance weighted share" is therefore 15.0% (10.0%
     x 1.5).

*    The sum of the "gross performance weighted shares" of all of the
     participants equals 122.2%.  Participant X's "net performance weighted pro
     rata share" is therefore 12.2% (15.0% divided by 122.2% = 12.2%).  His
     actual bonus will be $4,880 (12.2% of $40,000 Incentive Bonus Pool).

                              PLAN ADMINISTRATION
                              -------------------

                            Bonus Plan Contingencies
                            ------------------------


1.   The Corporate Performance Review Committee will convene to assess the
     degree to which the Bank's performance for the year conformed with the
     standards established in the corporate plan.  An unwarranted variance from
     the plan could result in adjustment to the "incentive bonus pool" - either
     upward or downward - by whatever amount is deemed appropriate by the
     Corporate Performance Review Committee.  For example, if the Committee
     determined management risk-taking unduly jeopardized "soundness", the
     "incentive bonus pool" would be reduced and, if considered necessary,
     incentive awards for the year might be eliminated.  On the other hand, if
     extraordinary mitigating circumstances beyond the control of management
     were to negatively impact profitability, an upward adjustment might be
     considered.  The Corporate Performance Review Committee should give due
     consideration to the performance of the Bank relative to its peer group and
     existing economic and competitive conditions when reviewing corporate
     performance with respect to the incentive plan. The Corporate Performance
     Review Committee may also elect to make exceptions to the plan in order to
     recognize the truly extraordinary contributions of individuals - separate
     from the Bank and the management group as whole.

                                                                              10

2.   The amount of the "incentive bonus pool" will under no circumstances
     exceed ten percent of the Bank's net income.  The net income base for this
     calculation should be net of the effect of the annual accrual for the
     incentive plan for that year (i.e., the accrual, net of associated tax
     benefits, should be added back to net income).  Net income is considered to
     be bottom line net income, including the net effect of investment
     securities gains/losses and other nonrecurring items, but exclusive of
     extraordinary one-time events, e.g., Co-operative Central Bank dividends,
     the sale of physical assets, etc.

3.   Under no circumstances will an incentive bonus be paid in any year for
     which a cash dividend on the Bank's stock has not been paid, or in any year
     in which cash dividends have been reduced.

4.   Bonus Eligibility Determination: active full-time employees are eligible
     for 100% participation in the Management Incentive Compensation Plan if
     they have been designated as a participant by the Chief Executive Officer
     in conjunction with the Salary Committee and have been working under a set
     of individual performance goals for 12 months prior to the effective date
     of the bonus. Otherwise eligible employees having less than 12 months but
     more than six months of employment working under a set of individual
     performance goals may be designated participants by the chief executive
     officer.

     Their level of participation will be limited by the amount of base salary
     received during the bonus period. Officers must be on the payroll at the
     time of the bonus disbursement to receive their bonus.

5.   The salary base to be used in the calculation is based upon earned salary
     for the period less any bonus payment included in that salary from a prior
     year.

6.   It should be fully understood that the described plan is not intended to
     interface, complement or otherwise relate with the Bank's regular Salary
     Administration Program.  The two are and should remain totally separate
     entities.

7.   The Management Incentive Compensation Plan will be administered and
     established at the discretion of the Bank's Board of Directors and can be
     discontinued or modified at any time at their discretion.  Furthermore,
     such bonus plan is not to be construed as a contract between employer and
     employee/officer.  Any and all right to participate in this Plan will cease
     upon the officer's termination.

                 SENIOR MANAGEMENT INCENTIVE COMPENSATION PLAN

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


A.   PROFITABILITY: The Bank's relative profitability will be determined by
     contrasting its Return on Assets (Net Income/Average Total Assets) against
     that of its peer group. Net Income will be calculated exclusive of
     extraordinary, one time events, e.g., Cooperative Central Bank
     distributions, the sale of physical assets, etc.

                         PERFORMANCE MANAGEMENT SYSTEM
                         -----------------------------


Objectives
- ----------

The purpose of the Performance Management System is to:

          Systemize the process of performance management in order to stress its
          importance as an integral part of Management Incentive Compensation.

          Provide a direct link to the Management Incentive Compensation System
          through a scoring system.

Description of the System.
- -------------------------  

The system is an objectives-driven approach to evaluating performance. In its
most simplistic form:

     1.   Officers establish their own objectives in conjunction with their
          superiors.

     2.   Objectives are weighted in terms of overall importance from 0 - 100%

     3.   Quarterly or semiannual reviews of objectives are conducted with
          superiors to ensure relevancy of objectives and weightings.

     4.   End of the year reviews of the levels of objectives attainment are
          conducted and an evaluation of level of achievement based on a scale
          of 0.0 - 2.0 is assigned to the overall objective. Definitions of
          objectives attainment are presented on Page 20 of the plan.

     5.   The cumulative total of the objectives attainment ratings (0.0 to 2.0)
          becomes the "performance multiplier" applied to determine individual
          participant "adjusted total salary."

binding upon and inure to the benefit of the transferee.  Any transfer or other
disposition in violation of the terms of this paragraph 2 shall be null and
void.

     3. The undersigned agrees that Sandwich's transfer agent shall be given an
appropriate stop transfer order and shall not be required to register any
attempted transfer of shares of Sandwich Common Stock, unless the transfer has
been effected in compliance with the terms of this Agreement.

     4. The undersigned acknowledges and agrees that any remedy at law for
breach of the foregoing provisions shall be inadequate and that, in addition to
any other relief which may be available, 1855 Bancorp shall be entitled to

date first above written.

                                   Very truly yours,

                              STOCKHOLDER  LETTER
                                        

Dear Stockholder:

Fiscal year 1997 was a record year for the Bank and its newly formed holding 
company, Sandwich Bancorp, Inc. The staff did a remarkable job to ensure that we
obtained our share of the business available from a growing economy. By taking
full advantage of what was a strong local market, we were able to exceed our
internal projections for new deposits and loans, as well as for net income.

For the twelve months ended December 31, 1997, net income increased 18% to $4.9
million, or $2.45 per share, compared to $4.1 million, or $2.13 per share, for
the comparable period in 1996. Deposits grew by 9% and net loans by 16%.

The Company's return on equity was a respectable 12.49% and our return on assets
was 0.98%. Book value per share increased from $20.31 to $21.63 at year's end.
During 1997 we also continued our policy of paying out approximately 50% of our
earnings in dividends. Stockholders received $1.25 in cash dividends in 1997,
compared to $1.05 in 1996.

This year's examination by the Banking Department of the Commonwealth of
Massachusetts resulted in our retaining an "Outstanding" Community Reinvestment
Act (CRA) rating once again. We take great pride in earning this excellent
rating. Over the past seven years we have had five CRA examinations - three by
the Commonwealth and two by the Federal Deposit Insurance Corporation (FDIC).
Each review rated the Bank's performance as "Outstanding," the highest
achievable category. Meeting the credit needs of the total community has been
good business, and it has been particularly rewarding to our staff and
Directors.

If you are a long-term stockholder, you are probably aware of the Company's
Mission Statement, which declares our objective of remaining a viable and
profitable independent community bank providing the highest possible level of
service and value to our customers and stockholders. As I write this message and
reflect upon the past 112 years of the Bank's history - including my personal
tenure here over the past two decades - I am convinced that the Company has met
that mission well. It has always been a viable institution and it has been been
profitable (with only one exception) every year in recent history. We have
always been a "Community Bank" in the best sense of anyone's definition,
striving to provide the highest level of service and value to our customers and-
as a public company for the past 12 years - to our stockholders.
<PAGE>
 
As you may know, on March 23, 1998, the Company entered into an agreement 
providing for the merger of the Company with The 1855 Bancorp, the parent 
company for CompassBank for Savings of New Bedford, Massachusetts, thereby
ending its long-standing independence. You might wonder why, after completing
such a successful year, the Bancorp's Directors would entertain such a
transaction. The answer to that question can be found in our Mission Statement "
 ... providing the highest level of value to our stockholders."

The past year was not only a record year for Sandwich Bancorp and Sandwich Co-
operative Bank, it was a record year for the stock market and for the market
value of publicly traded banks, as well. The Directors' recommendation that the
Bank be acquired in 1998 is an expression of their conviction that now is the
optimal time to enter into such a transaction. The recommendation is based on
their strong belief that a merger at this time is in the best interest of the
Bank's stockholders and its stakeholders. They have worked hard to structure an
agreement that will result in an on-going institution that will provide the best
possible opportunities for our employees, our customers, and the communities we
serve, while meeting their fiduciary responsibility to stockholders.

While the name over the door will change, the legacy of Sandwich Co-operative
Bank will hopefully live on in the minds of all of those associated with this
institution over the years--and the spirit of Sandwich Co-operative Bank will be
passed on to become an integral part of a new entity whose mission will be to
continue to provide a high level of value to customers and the community.

I am honored to have been associated with this organization. The Board of
Directors joins me in thanking our employees, customers and stockholders whose
dedication, loyalty and support over the years have made the Bank what it is
today.

Sincerely,

Frederic D. Legate
President and Chief Executive Officer

At December 31, 1996, the Bank's total assets were $464,555,000 as compared to
$426,515,000 at December 31, 1995. The increase was largely attributable to an
increase in loan production throughout 1996 offset by a decrease in the Bank's
investment portfoliPamela J. ButtrickFinancial Printing GroupAt December 31,
1997, the Company's total assets were $518,697,000 as compared to $464,555,000
at December 31, 1996, an increase of $54,142,000 or 11.7%. The increase is
largely attributable to an increase in loan production throughout 1997 offset by
a decrease in the Company's investment portfolio, including investment
securities held to maturity and available for sale. Total cash and cash
equivalents at December 31, 1997 totaled $15,967,000 compared to $11,718,000 at
December 31, 1996, an increase of $4,249,000. The Company's investment
portfolio, including other short-term investments, investment securities
available for sale and investment securities held to maturity, decreased
approximately $2,923,000 to $110,673,000. Maturities on investment securities
and cash flow from collateralized mortgage obligations (CMOs) were reinvested
into loans. The continuing improvement in the New England and local real estate
markets has had a positive impact on the Company's loan portfolio. As evidence
of this, the Company's loan portfolio, net of allowance for loan losses,
increased approximately $49,539,000 or 15.6% to $366,642,000, through loan
originations and purchases offset by principal amortization and early payoffs.

  Deposits totaled $423,014,000 at December 31, 1997 compared to $388,249,000 at
December 31, 1996, an increase of $34,765,000 or 9.0%. Borrowings totaled
$45,601,000 at December 31, 1997 compared to $32,073,000 at December 31, 1996,
an increase of $13,528,000 due to an increase in advances from the Federal Home
Loan Bank of Boston used to finance loan originations, loan purchases and the
purchase of investment securities.

  Non-performing assets, which include non-accrual loans and real estate
acquired by foreclosure (OREO) decreased $374,000, from $4,551,000 at December
31, 1996, to $4,177,000 at December 31, 1997. At December 31, 1995, non-
performing assets totaled $5,038,000. Non-accrual loans decreased by $505,000,
from $4,086,000 at December 31, 1996, to $3,581,000 at December 31, 1997. Other
real estate owned, however, increased by $131,000, from $465,000 at December 31,
1996, to $596,000 at December 31, 1997.

  The Company's results of operations are affected by interest rate levels, the
amount of non-performing assets, the health of the real estate sector of the
economy, investment securities transactions and seasonal trends. At December 31,
1997, non-performing assets totaled $4,177,000 or 0.81% of total assets, of
which $3,319,000 are residential properties, $560,000 are investment properties,
and the balance reflects other land loans and properties.

  Management anticipates continued stability in the economy in 1998. However,
the local real estate market continues to represent a risk to the Company's loan
portfolio and could result in an increase in, and reduced values of, properties
acquired by foreclosure. Accordingly, higher provisions for loan losses and
foreclosed property expense may be required should economic conditions worsen or
the levels of the Company's non-performing assets increase. Management continues
to engage experienced outside consultants to assist in loan reviews in an effort
to minimize risk and control exposure.

Results of Operations

Comparison of years ended December 31, 1997 and December 31, 1996

General

Net income for the year ended December 31, 1997 amounted to $4,860,000 compared
with net income of $4,137,000 for the year ended December 31, 1996. The
principal reason for the increase was improvement in net interest and dividend
income, resulting from growth in the residential loan portfolio. Additionally,
non-interest expense decreased as no provision for the special, one-time deposit
insurance assessment from the Savings Association Insurance Fund ("SAIF") was
incurred in the 1997 period. Decreases in net gains realized on the sale of
loans in the secondary market and decreases in service charges also occurred for
the year ended December 31, 1997. The Company's operating results depend largely
upon its net interest margin which is the difference between the income earned
on loans and investments, and the interest expense paid on deposits and
borrowings, divided by total interest earning average assets. The net interest
margin is affected by the economic and market factors which influence interest
rates, loan demand and deposit flows. The interest rate margin decreased to
3.71% for the year ended December 31, 1997, from 3.94% for the year ended
December 31, 1996.

  Trends in the real estate market locally and in New England impact the Company
because of its real estate loan portfolio. If the local and New England real
estate markets show signs of weakness, additional provisions for loan losses may
be necessary in the future. In addition, various regulatory agencies, as an
integral part of their examination process, periodically review the Company's
allowance for loan losses. Such agencies may require the Company to recognize
additions to the allowance based on information available at the time of their
review.

Interest and Dividend Income

Interest and dividend income increased by $3,608,000 or 11.2% to $35,917,000 for
the year ended December 31, 1997 when compared to the year ended December 31,
1996. Interest on loans increased $3,525,000 or 14.3% as a result of an increase
in the average balance outstanding of $53,800,000, and a decrease in non-accrual
loans, partially offset by a decrease in the average rate earned on the
portfolio from 8.36% in 1996 to 8.08% in 1997. Interest and dividends on
investment securities and other short-term investments increased by $58,000 or
0.8%.

  Non-accrual loans decreased $505,000 to $3,581,000 when compared to the year
ended December 31, 1996 balance of $4,086,000. Restructured loans at December
31, 1997 amounted to approximately $105,000 compared to the December 31, 1996
balance of $258,000. Typically, restructured loans are restructured to provide
either a reduction of the interest on the loan principal or an extension of the
loan maturity.

  The following table presents changes in interest and dividend income, interest
expense and net interest and dividend income which are attributable to changes
in the average amounts of interest-earning assets and interest-bearing
liabilities outstanding and/or to changes in the rates earned or paid thereon.

Interest Expense

Total interest expense increased $2,530,000 to $18,322,000 for the year ended
December 31, 1997, from $15,792,000 for the year ended December 31, 1996.
Interest expense from deposits increased by $709,000 or 4.8%. The rise reflects
the increase in average interest-bearing deposits balance outstanding of
$15,719,000. Interest expense from borrowed funds increased $1,821,000 primarily
due to an increase in the average balance outstanding of $30,242,000. Interest
rates on interest-bearing deposits and borrowed funds for the year ended
December 31, 1997 increased to 4.45% from 4.32% when compared to 1996.

Provision for Loan Losses

The provision for loan losses charged to earnings amounted to $750,000 and
$265,000 for the years ended December 31, 1997 and 1996, respectively. The
Company increased its provision for loan losses for the year ended December 31,
1997 as compared to the year ended December 31, 1996 as a result of the overall
increase in the loan portfolio and an increase in specific loan charge-offs.
Non-accrual loans as a percentage of total loans outstanding were 0.97% at
December 31, 1997 and 1.27% at December 31, 1996. As of December 31, 1997 and
1996, the Company had identified $200,000 and $584,000, respectively, of
potential problem loans. Management's analysis of the loan portfolio considers
risk elements by loan category, and also the prevailing economic climate and
anticipated future uncertainties. Future adjustments to the allowance for loan
losses may be necessary if economic conditions differ substantially from
assumptions used in performing the analysis, or the levels of the Company's non-
performing assets increase significantly.

Non-Interest Income

Non-interest income decreased $118,000 for the year ended December 31, 1997
compared to the 1996 period. The decrease was mainly the result of a decline of
$94,000 in service charges along with a decrease in gain on sale of loans of
$75,000, partially offset by a $55,000 increase in gains on sales of investment
securities, net. The decrease in gain on sale of fixed rate loans in the
secondary market was due to less favorable market interest rates during the year
1997. The decrease in service charges resulted from an overall decrease in fees
received for checking account services the Company provides to its customers.

Non-Interest Expense

Total non-interest expense consists of salaries and employee benefits, occupancy
and equipment, FDIC deposit insurance, advertising, data processing service
fees, foreclosed property expense, amortization of core deposit and other
intangibles, and other expenses. Also included are the costs of carrying and
administering non-performing loans.

  Non-interest expense decreased as no provision for the special, one-time
deposit insurance assessment from SAIF was incurred in 1997, while a $280,000
provision was incurred in 1996.

Income Taxes

The Company recognized income tax expense of $2,480,000 for the year ended
December 31, 1997 and $2,621,000 in the comparable period of 1996. Both these
amounts differ from the expected tax expense of 34% of income before income
taxes. The major reasons for these variances relate to state income tax expense
(net of the federal tax benefit), tax exempt income, dividend received deduction
and changes in the valuation allowance for deferred income taxes. Factors such
as the Company's earnings and equity securities gains or losses will affect
income taxes recorded in the financial statements. At December 31, 1997, the
Company had a net deferred income tax asset of $2,948,000, which is net of the
valuation allowance of $56,000. Management establishes a valuation allowance
when it is more likely than not that some portion of the gross deferred income
tax assets will not be realized. The valuation allowance at year end applies
principally to the tax effect of the state income tax benefit attributable to
the gross deductible temporary differences. The primary sources of recovery of
the deferred tax assets are taxes paid that are available for carry back of
$6,100,000 in 1997, 1996 and 1995, and the expectation that the deductible
temporary differences will reverse during periods in which the Company generates
taxable income.

  During the fourth quarter of 1997, the Company implemented two tax strategies
in order to recognize the benefit of net, unused capital loss carryforwards that
were due to expire on December 31, 1997. The Company entered into a
sale/leaseback agreement with a third party for three of its offices. In
addition, the Company sold equity securities that were maintained in a Grantors
Trust in order to generate capital gains. The combination of these two
transactions allowed the Company to recognize a $576,000 benefit through a
reduction in the deferred tax asset valuation allowance.

Comparison of years ended December 31, 1996 and December 31, 1995

General

Net income for the year ended December 31, 1996 amounted to $4,137,000 compared
with net income of $3,436,000 for the year ended December 31, 1995. The
principal reasons for the increase were increased net interest and dividend
income, increased gains realized on the sale of loans and a decrease in
provisions for loan losses and FDIC deposit insurance expense, partially offset
by increases in other non-interest expenses and a special one-time deposit
insurance assessment from the Savings Association Insurance Fund ("SAIF"). The
Bank's operating results depend largely upon its net interest margin which is
the difference between the income earned on loans and investments, and the
interest expense paid on deposits and borrowings, divided by total interest
earning average assets. The net interest margin is affected by the economic and
market factors which influence interest rates, loan demand and deposit flows.
The interest rate margin decreased to 3.94% for the year ended December 31,
1996, from 3.98% for the year ended December 31, 1995.

Interest and Dividend Income

Interest and dividend income increased by $1,636,000 or 5.3% to $32,309,000 for
the year ended December 31, 1996 when compared to the year ended December 31,
1995. Interest on loans increased $2,462,000 or 11.1% as a result of an increase
in the average balance outstanding of $32,276,000, and a decrease in non-accrual
loans, partially offset by a decrease in the average rate earned on the
portfolio from 8.45% in 1995 to 8.36% in 1996. Interest and dividends on
investment securities and other short-term investments decreased by $826,000 or
9.8% as a result of the decrease in the average balance outstanding to
$122,794,000 and a decrease in the yield on investment securities to 6.17% for
the year ended December 31, 1996, as compared to 6.27% for the year ended
December 31, 1995.

Interest Expense

Total interest expense increased $959,000 to $15,792,000 for the year ended
December 31, 1996, from $14,833,000 for the year ended December 31, 1995.
Interest expense from deposits increased by $355,000 or 2.5%. The rise reflects
the increase in average deposits balance outstanding of $2,219,000, along with
an increase in market interest rates over the period. Interest expense from
borrowed funds increased $604,000 primarily due to an increase in the average
balance outstanding of $10,576,000, and an increase in the interest rates over
the period. Interest rates on deposits and borrowed funds for the year ended
December 31, 1996 increased to 4.32% from 4.20% when compared to 1995.

Provision for Loan Losses

The provision for loan losses charged to earnings amounted to $265,000 and
$597,000 for the years ended December 31, 1996 and 1995, respectively. The Bank
decreased its provision for loan losses for the year ended December 31, 1996 as
compared to the year ended December 31, 1995 due to a decline in specific loan
charge-offs. Non-accrual loans as a percentage of total loans outstanding were
1.27% at December 31, 1996 and 1.70% at December 31, 1995. As of December 31,
1996 and 1995, the Bank had identified $584,000 and $349,000, respectively, of
potential problem loans. Management's analysis of the loan portfolio considers
risk elements by loan category, and also the prevailing economic climate and
anticipated future uncertainties. Future adjustments to the allowance for loan
losses may be necessary if economic conditions differ substantially from
assumptions used in performing the analysis, or the levels of the Bank's non-
performing assets increase significantly.

Non-Interest Income

Non-interest income increased $121,000 for the year ended December 31, 1996
compared to the 1995 period. The increase was mainly the result of the increase
in gain on sale of loans of $210,000, along with an increase of $41,000 in
service charges, partially offset by a decrease of $214,000 in gain on sale of
branch deposits. The increase in gain on sale of loans was due to favorable
market interest rates during the year 1996 and the recording of the value of the
mortgage loan servicing rights. The increase in service charges resulted from
the overall increases in fees for services the Bank provides to its customers.

Non-Interest Expense

Total non-interest expense consists of salaries and employee benefits, occupancy
and equipment, FDIC deposit insurance, advertising, data processing service
fees, foreclosed property expense, amortization of core deposit and other
intangibles and other expenses. Also included are the costs of carrying and
administering non-performing assets.

  The slight decrease in non-interest expense for the year when compared to the
prior period is attributed primarily to decreases in FDIC deposit insurance,
foreclosed property expense and amortization of core deposit intangible, offset
partially by increases in salaries and employee benefits and occupancy and
equipment, and the one-time special assessment of $280,000 on SAIF-assessable
deposits.

Income Taxes

The Bank recognized income tax expense of $2,621,000 for the year ended December
31, 1996 and $2,169,000 in the comparable period of 1995. Both these amounts
differ from the expected tax expense of 34% of income before income taxes. The
major reasons for these variances relate to state income tax expense (net of the
federal tax benefit), tax exempt income, dividend received deduction and changes
in the valuation allowance for deferred income taxes. Factors such as the Bank's
earnings and equity securities gains or losses will affect income taxes recorded
in the financial statements. At December 31, 1996, the Bank had a net deferred
income tax asset of $2,469,000, which is net of the valuation reserve of
$632,000. Management establishes a valuation reserve when it is more likely than
not that some portion of the gross deferred income tax asset will not be
realized. The valuation reserve at year end applies principally to the tax
effect of the capital loss carryforward and the state income tax benefit
attributable to the gross deductible temporary differences. The primary sources
of recovery of the deferred tax asset are taxes paid that are available for
carry back of $5,400,000 in 1996, 1995 and 1994, and the expectation that the
deductible temporary differences will reverse during periods in which the Bank
generates taxable income.

Asset and Liability Management and Market Risk

The Company's pre-tax earnings depend primarily on its net interest income, the
difference between the income it receives on its loan portfolio and other
investments and its cost of money, consisting primarily of interest paid on
savings deposits, FHLB advances and other borrowings. Net interest income is
affected by (i) the difference ("interest rate spread") between rates of
interest earned on its interest-earning assets and rates paid on its interest-
bearing liabilities and (ii) the relative amounts of its interest-earning assets
and interest-bearing liabilities. When interest-earning assets approximate or
exceed interest-bearing liabilities, any positive interest rates spread will
generate net interest income. Thrift institutions have traditionally used
interest rate spreads as a measure of net interest income. Another indicator of
an institution's net interest income is its "net yield on interest-earning
assets" which is net interest income divided by average interest-earning assets.

  Market risk is the risk of loss from adverse changes in market prices and
rates. The Company's market risk arises primarily from interest rate risk
inherent in its lending, security investments, and deposit taking activities. To
that end, management actively monitors and manages its interest rate risk
exposure.

  The Company's primary objective in managing interest rate risk is to minimize
the adverse impact of changes on the  Company's net interest income and capital,
while adjusting the Company's rate-sensitive asset and liability structure to
obtain the maximum net yield on that structure. The Company relies primarily on
this structure to control interest rate risk. However, a sudden and substantial
shift in interest rates may adversely impact the Company's earnings to the
extent that the interest rate earned on interest-earning assets and interest
paid on interest-bearing liabilities do not change at the same frequency, to the
same extent or on the same basis.

  A method used by the Company to measure the interest rate risk exposure is the
interest rate sensitivity "GAP", which is the difference between assets and
liabilities subject to rate change over specific time periods. There are
limitations to GAP analysis. However, as rates on different assets and
liabilities may not move to the same extent in any given time period,
competition may affect the ability of the Company to change rates on particular
loan or deposit products. The following table discloses the Company's interest-
sensitive financial instruments, categorized by expected maturity and their fair
values at December 31, 1997. Market risk sensitive instruments are generally
defined as on- and off-balance sheet and other financial instruments.
<PAGE>
 
  The following table presents the Company's interest sensitivity gap between
interest-earning assets and interest-bearing liabilities at December 31, 1997.
In addition the table indicates the Company's sensitivity gap at various periods
and the ratio of the Company's interest-earning assets to interest-bearing
liabilities at various periods. Term certificates are based upon contractual
maturities.

(1) Expected maturities are contractual maturities adjusted for projected
prepayments of principal. The Company uses certain assumptions to estimate fair
values and expected maturities. For assets, expected maturities are based upon
contractual maturities, projected repayments and prepayments of principal. The
prepayment experience reflected herein is based on the Company's historical
experience. The Company's average Constant Prepayment Rate ("CPR") is 13.9% and
18.9% per year of its fixed-rate and adjustable-rate portfolios, respectively,
for interest-earning assets. For deposits, "decay rates" have been applied to
estimate deposit runoff of 14.3% per year based on the Company's own historical
experience. The actual maturities of these instruments could vary substantially
if future prepayments differ from the Company's historical experience. Off-
balance sheet risk includes commitments to extend credit and sell loans. At
December 31, 1997, the contract or notional amount of these commitments is
$46,200,000 and $6,100,000, respectively.  Their fair values have been
estimated as $500,000.
<PAGE>
 
Liquidity and Capital Resources

  The Company's primary source of liquidity is dividends from its bank
subsidiary. Dividends from the Bank to the Company totaled $768,000 in 1997.The
Company made payments of dividends to stockholders in the amount of $672,000
during the fourth quarter ended December 31, 1997.

  The Bank's primary sources of liquidity are deposits, loan payments and
payoffs, investment income and maturities and principal payments on investments,
mortgage-backed securities and CMOs, advances from the Federal Home Loan Bank of
Boston, and other borrowings. Management believes it is prudent to maintain an
investment portfolio that not only provides a source of income, but additionally
provides a source of liquidity, through its principal paydowns and maturities,
to meet lending demands and fluctuations in deposit flows. These various sources
of funds are utilized to fund withdrawals, new loans and other investments, as
well as to pay on-going expenses of operation. At December 31, 1997, the Bank
had total unused lines of credit and commitments to originate loans of
$38,784,000, unadvanced portions of construction loans of $7,188,000 and
commercial standby letters of credit of $218,000. In addition, the Bank had
commitments to sell loans totaling $6,149,000. Management believes that the
Bank's various sources of funds are sufficient to meet its commitments in the
ordinary course of business. For further information, see notes to consolidated
financial statements.

  The Bank is required to maintain certain levels of capital (stockholders'
equity) pursuant to FDIC regulations. At December 31, 1997, the Bank's capital
level was significantly in excess of required minimums. For additional
information on capital ratios of the Company and the Bank, see note 11 of notes
to consolidated financial statements.

Impact of the Year 2000 Issue

The Year 2000 (Y2K) Issue is the result of computer programs being written using
two digits, rather than four to define the applicable year. Any of the Company's
computer programs that have date-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.

  The Company began addressing the Year 2000 Issue in the Fall of 1996. The
Company formed a Y2K Review Team which is composed of the Company's internal
Management Information Systems Steering Committee and all members of our Senior
Management Group. A Plan was developed by the Y2K Review Team and approved by
the Board of Directors. The Team has completed an assessment, identifying
mission critical systems and has initiated formal communications with all third
party vendors to determine the compliance status of any systems utilized by the
Company. Based upon the results of the assessment, the Company has determined
that there will be a need to replace portions of its existing hardware and
require upgrades to a portion of its software systems. The Company does not
utilize internally written and supported proprietary code. All software is
purchased or licensed through widely recognized providers.

  The Company Plan calls for replacement and upgrading to take place with
allowances for extensive testing within time frames established by the Federal
Financial Institutions Examination Council (FFIEC). The Y2K Review Team meets no
less than quarterly and provides quarterly reports to the Board of Directors.
The Company has notified its customers of the Year 2000 Issue in the Fall 1997
issue of the Company newsletter, "Currents". The  newsletter outlines the issue
and the Company's Plan to address it. Also, letters have been sent to all
commercial loan customers informing them of the Year 2000 Issue and how it can
impact businesses.

  The Company had included approximately $150,000 for the replacement and
upgrade of specific hardware in its 1998 capital budget. An additional IS
Technician position has been planned and included in the budget for the IS
Department in the second quarter of 1998. The new employee will assist in the
deployment of Y2K compliant hardware, upgrade software and facilitate the Y2K
testing of all systems.

  The Company will utilize internal and, if necessary, external resources to
upgrade, replace, and test the software and systems for Year 2000 Issue
modifications. The Company plans to complete the Year 2000 Issue project no
later than March 31, 1999.

Recent Accounting Pronouncements

In February 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 129, "Disclosure of Information about Capital Structure", which is effective
for 1997 financial statements. The Company's disclosures currently comply with
the provisions of this statement.

  In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income".
SFAS No. 130 establishes standards for reporting and displaying comprehensive
income, which is defined as all changes to equity except investments by and
distributions to shareholders. Net income is a component of comprehensive
income, with all other components referred to in the aggregate as other
comprehensive income. This statement is effective for 1998 financial statements
and is not expected to have a material effect on the financial statements.

  Also in June 1997 the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information", which establishes standards for
reporting information about operating segments. An operating segment is defined
as a component of a business for which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and evaluate performance. This statement
requires a company to disclose certain income statement and balance sheet
information by operating segment, as well as provide a reconciliation of
operating segment information to the company's consolidated balances. This
statement is also effective for 1998 financial statements and is not expected to
have a material effect on the financial statements.

Years ended December 31, 1997, 1996 and 1995


(1) Basis of Presentation and Summary of Significant Accounting Policies

General

Sandwich Bancorp, Inc. (the "Company") is a Massachusetts corporation and the
holding company of Sandwich Co-operative Bank (the "Bank"). The Sandwich Co-
operative Bank was organized as a Massachusetts chartered co-operative bank in
1885. The Bank merged with Wareham Co-operative Bank in May 1982. In July 1986,
the Bank converted from mutual to stock form through the sale and issuance of
1,820,833 shares of common stock, par value $1.00 per share (the "Common
Stock"). The Bank's deposits are insured by the Federal Deposit Insurance
Corporation ("FDIC"), an agency of the federal government, up to $100,000 per
insured depositor, with additional insurance to the total amount of the deposit
provided by the Share Insurance Fund of The Co-operative Central Bank (the
"Central Bank"), a deposit insuring entity chartered by the Commonwealth of
Massachusetts. The Bank is subject to regulation by the Massachusetts
Commissioner of Banks ("Commissioner") and the FDIC.

  On January 28, 1997, Sandwich Co-operative Bank announced that its Board of
Directors had approved a plan providing for the formation of a holding company
with the Bank as the principal subsidiary. Under the plan, each existing share
of the Bank's Common Stock was converted into one share of Common Stock in the
new holding company. As a result of this reorganization, the Bank's stockholders
became the owners of the newly formed holding company, which in turn owns all of
the outstanding stock of the Bank. The holding company formation resulted in no
change to the Bank's business, management, office locations or customer service,
and the holding company's corporate documents did not include any additional
anti-takeover provisions. The holding company reorganization was consummated on
September 30, 1997.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of
Sandwich Bancorp, Inc. (the "Company") and its wholly owned subsidiaries, The
Sandwich Co-operative Bank, The Sextant Corporation, Sandwich Securities
Corporation and Sextant Securities Corporation. All significant intercompany
accounts and transactions have been eliminated in consolidation.

  The accompanying consolidated financial statements have been prepared in
conformity with generally accepted accounting principles and general practices
within the banking industry. In preparing the financial statements, management
is required to make estimates and assumptions that affect the reported amounts
of assets and liabilities as of the date of the balance sheet and income and
expenses for the period. Actual results could differ from those estimates.

  Material estimates that are particularly susceptible to change relate to the
determination of the allowance for loan losses. This estimate is dependent on
future economic and overall business conditions.

  Certain reclassifications have been made to previously reported balances to
conform with the current period's presentation.
Investment Securities

Debt securities that the Bank has the positive intent and ability to hold to
maturity are classified as held-to-maturity and reported at amortized cost; debt
and equity securities that are bought and held principally for the purpose of
selling in the near term are classified as trading and reported at fair value,
with unrealized gains and losses included in earnings; and debt and equity
securities not classified as either held-to-maturity or trading are classified
as available-for-sale and reported at fair value, with unrealized gains and
losses excluded from earnings and reported as a separate component of
stockholders' equity, net of applicable taxes.

  Securities held to maturity, including bonds, mortgage-backed securities &
CMOs are stated at cost, adjusted for amortization of premiums or accretion of
discounts, calculated using a method which approximates the interest method. The
basis for valuation reflects management's intention and ability to hold these
securities to maturity.

  Securities available for sale consisting of government bonds, adjustable rate
mortgage-backed securities and marketable equity securities are stated at fair
value, with unrealized gains and losses, net of tax, excluded from earnings and
reported as a separate component of stockholders' equity until realized. Fair
value is based upon quoted market prices or dealer quotes as of the reporting
date.

  Gains and losses on the sale of investment securities are recognized at the
time of sale on a specific identification basis. Unrealized losses deemed to be
other than temporary declines in value are charged to operations.

  Premiums and discounts on investment and mortgage-backed securities are
amortized or accreted into income by a method that estimates the interest method
adjusted for prepayments. If a decline in fair value below the amortized cost
basis of an investment or mortgage-backed security is judged to be other than
temporary, the cost basis of the investment is written down to fair value as a
new cost basis and the amount of the write-down is included as a charge against
income.

                  Notes to Consolidated Financial Statements

Loans

Loans are reported at their principal amount outstanding, net of any unearned
discount and deferred loan fees. Interest income on loans is credited to income
based on loan principal amounts outstanding at appropriate interest rates.

  Unearned discount and premium on loans is credited or charged to income on a
basis which approximates the interest method.

  Accrual of interest income on loans is discontinued and unpaid accrued
interest is reversed when management determines that borrowers will be unable to
meet contractual obligations and/or when loans are ninety days or more in
arrears, except in certain instances where management believes that collateral
held by the Bank is clearly sufficient for full satisfaction of both principal
and interest. Loans will be removed from non-accrual when the principal and
interest become current and the loan is considered fully collectable.

  Loan origination fees and certain direct origination costs are offset and the
resulting net amount is deferred and amortized as an adjustment of the yield on
the related loans.

  Loans held for sale are carried at the lower of cost or estimated fair value.
Fair value is determined based on outstanding investor commitments or, in the
absence of such commitments, current investor yield requirements.

Allowance for Loan Losses

The allowance for loan losses is available for probable credit losses inherent
in the loan portfolio. The allowance is increased by provisions charged to
operations on the basis of many factors including the risk characteristics of
the portfolio, current economic conditions and trends in loan delinquencies and
charge-offs. Realized losses, net of recoveries, are charged directly to the
allowance.

  The Bank accounts for impaired loans, except loans accounted for at fair value
or at the lower of cost or fair value, at the present value of the expected
future cash flows discounted at the loan's effective interest rate or the fair
value of the collateral if the loan is collateral dependent. Impaired loans
include commercial, commercial real estate and individually significant mortgage
or consumer loans for which it is probable the Bank will not collect all amounts
due according to the terms of the loan agreement. Impairment on troubled debt
restructurings is measured using the premodification rate of interest.

  While management uses the information available in establishing the allowance
for loan losses, future adjustments to the allowance may be necessary if
economic conditions differ substantially from the assumptions used in making the
evaluation. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Bank's allowance for loan
losses. Such agencies may require the Bank to recognize additions to the
allowance based on judgments different from those of management.

Real Estate Acquired by Foreclosure

Real estate acquired by foreclosure is comprised of properties acquired through
foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Real
estate acquired by foreclosure is initially recorded at the lower of the
carrying value of the loan or the fair value of the property minus costs to
sell. Fair value is based upon a market appraisal prepared by a State certified
appraiser not more than 30 days prior to the date of the foreclosure. Losses
arising from the acquisition of such properties are charged against the
allowance for loan losses.

  Operating expenses and any subsequent provisions to reduce the carrying value
to fair value minus cost to sell are charged to current period earnings. Gains
upon disposition are reflected in earnings as realized. Realized losses are
charged to the valuation allowance.

Office Properties and Equipment

Office properties and equipment are stated at cost less accumulated depreciation
and amortization. Depreciation and amortization are computed on the straight-
line method over the estimated useful lives of the related assets or terms of
leases.

Pension Costs and Employee Benefits

The Bank accounts for pension and postretirement benefits on the net periodic
cost method for financial reporting purposes. This method recognizes the
compensation cost of an employee's benefit over that employee's approximate
service period.

  The Company continues to follow APB Opinion No. 25 "Accounting for Stock
Issued to Employees" as permitted by Statement of Financial Accounting Standards
No. 123 "Accounting for Stock-Based Compensation" ("SFAS 123"). For companies
that elect to continue using APB 25, SFAS 123 requires disclosure of the pro
forma effect of using the fair value method of accounting for stock-based
compensation that is encouraged by SFAS 123. See note 12 of notes to
consolidated financial statements for the expanded disclosures required by SFAS
123 regarding pro forma net income and earnings per share.

Core Deposit Intangible

Core deposit and other intangibles are amortized to expense over a period of ten
years using an accelerated method. The unamortized balance of these intangibles
are evaluated periodically for their recoverability.

Income Taxes

The Bank recognizes income taxes under the asset and liability method. Under
this method, deferred tax assets and liabilities are established for the
temporary differences between the accounting basis and the tax basis of the
Bank's assets and liabilities at enacted tax rates expected to be in effect when
the amounts related to such temporary differences are realized or settled. A
valuation allowance related to deferred tax assets is established when, in
management's judgment, it is more likely than not that all or a portion of such
deferred tax assets will not be realized. Changes in the valuation allowance are
reflected as deferred income tax expense or benefit. The deferred tax asset is
adjusted for changes in the federal and state tax rates.

Earnings Per Share

Effective December 31, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "Earnings per Share" ("SFAS 128"). SFAS 128
replaces the existing accounting rules for computing earnings per share and
makes the new rules comparable to international standards. Basic earnings per
share excludes common stock equivalents and is computed by dividing net income
by the weighted average number of common shares outstanding for the period.
Diluted earnings per share gives effect to all potential dilutive common shares
using the average market price of the Company's common stock for the period plus
the weighted average number of common shares outstanding for the equivalent
period of time. All prior period earnings per share have been restated to comply
with SFAS 128.

  The numerator in the earnings per share calculation is net income, as
reported, for both the basic and dilutive calculations.

(4) Loans

The Bank's lending activities are conducted principally in the Southeastern and
Cape Cod areas of Massachusetts. The Bank grants single-family and multi-family
residential loans, commercial real estate loans and a variety of consumer loans.
In addition, the Bank grants loans for the construction of residential homes,
multi-family properties, commercial real estate properties and for land
development. Most loans granted by the Bank are either collateralized by real
estate or guaranteed by Federal and local governmental authorities. The loans

</TABLE>

A valuation allowance is provided when it is more likely than not that some
portion of the gross deferred tax asset will not be realized. Management has
established a valuation allowance principally for the tax effect of the capital
loss carry forward and the state income tax benefit derived from the gross
deductible temporary differences. The primary sources of recovery of the
deferred tax asset are taxes paid that are available for carryback of $6.1
million in 1997, 1996 and 1995, and the expectation that the deductible
temporary differences will reverse during periods in which the Bank generates
taxable income. As of December 31, 1997, the capital loss carryforward
approximates $25,000 and expires in 1998.

  The balance of the pre-1988 bad debt reserves continue to be subject to
provision of present law that require recapture in the case of certain excess
distributions to shareholders. The tax effect of pre-1988 bad debt reserves
subject to recapture in the case of certain excess distributions is
approximately $2,300,000.

                  Notes to Consolidated Financial Statements

(11) Retained Earnings

The Bank is subject to various regulatory capital requirements administered by
federal banking agencies. Failure to meet minimum capital requirements can
initiate certain mandatory, and possibly additional, discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings, and other factors.

  Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of Total and Tier I capital (as defined in the regulations) to risk
weighted assets (as defined), and of Tier 1 capital (as defined) to average
assets (as defined). Management believes that as of December 31, 1997, the Bank
meets all capital adequacy requirements to which they are subject.

  As of December 31, 1997, the most recent notification from the FDIC
categorized the Bank as well capitalized under the prompt corrective action
provisions. To be categorized as well capitalized, the Bank must maintain Total
capital risk-based, Tier 1 capital risk-based and Tier 1 capital leverage ratios
as set forth in the table. There are no conditions or events since that
notification that management believes would cause a change in the Bank's
categorization.

  The Company's and Bank's actual capital amounts and ratios in addition to the
minimum capital requirements and well capitalized capital requirements at
December 31 follow:

worth requirements or if such declaration and payment would otherwise violate
regulatory requirements.

(12) Employee Benefits

Postretirement Benefits

The Bank provides postretirement medical benefits for employees that were hired
before July 1, 1993. The Bank accrued postretirement benefits other than
pensions (medical benefits) over the periods during which employees render
service. The Bank amortizes the transition obligation from January 31, 1993 into
operations over a 20 year period. Expense for the years ended December 31, 1997,
1996 and 1995 was approximately $54,000, $53,000 and $51,000, respectively.

Pension Plan

The Bank provides pension benefits for its employees through membership in the
Co-operative Banks Employee's Retirement Association. The Plan is a multi-
employer, noncontributory, defined benefit plan. Bank employees become eligible
after attaining age 21 and one year of service. The Plan is funded by the Bank
and benefits become fully vested after six years of eligible service.

  Pension expense was approximately $317,000, $309,000 and $224,000 for the
years ended December 31, 1997, 1996 and 1995, respectively.

Stock Option Plan

During 1986, the Board of Directors adopted a Stock Option Plan for the benefit
of officer and non-officer employees and reserved 182,083 shares of authorized
but unissued common stock. Similarly, in 1994, the Board of Directors instituted
the 1994 Stock Option and Incentive Plan and reserved 90,000 shares of common
stock. Under terms of the Plans, the exercise price of any option granted will
not be less than the fair market value of the common stock on the date of grant
of the option and options may not have a maximum term of more than ten years.

A summary of the activity under the Plan follows:

There are 3,828 options available for future grant at December 31, 1997.

  At December 31, 1997, the per share weighted average fair value of stock
options granted during 1997, 1996 and 1995 was $18.05, $7.39 and $5.20 ,
respectively on the date of grant using the Black Scholes option-pricing model
with the following weighted average assumptions for 1997, 1996 and 1995:
expected dividend yield of 2.42% for 1997 and 3.69% for 1996 and 1995, risk-free
interest rate of 5.92% for 1997 and 6.56% for 1996 and 1995, volatility of the
Company's common stock of 35% for 1997 and 45% for 1996 and 1995 and an expected
life of ten years.

  The Company applies APB Opinion No. 25 in accounting for its Plan and,
accordingly, no compensation cost has been recognized for its stock options in
the financial statements. Had the Company determined compensation cost based on
the fair value at the grant date for its stock options under SFAS No. 123, the
Company's net income would have been reduced to the pro forma amounts indicated
below:

</TABLE>

  Pro forma net income reflects only options granted in 1997, 1996 and 1995.
Therefore, the full impact of calculating compensation cost for stock options
under SFAS No. 123 is not reflected in the pro forma net income amounts
presented above because compensation cost is reflected over the options' vesting
period of three years and compensation cost for options granted prior to January
1, 1995 is not considered.

                  Notes to Consolidated Financial Statements

Employee Bonus Plan

The Bank has an employee bonus and management incentive compensation plan in
which employees are eligible to participate. The Plan provides for awards based
upon a combination of Bank and individual performance measured against
predetermined annual goals, based on specific performance objectives. The Plan
is administered by the Bank's president under the direction of the Board of
Directors.

  Incentive compensation expense of $248,000, $188,000 and $235,000 was charged
to expense for the years ended December 31, 1997, 1996 and 1995, respectively.
Employee Stock Ownership Plan

Effective May 1, 1989, the Bank established an Employee Stock Ownership Plan
("ESOP") for the exclusive benefit of participating employees, defined as age 21
or older who have completed one year of service. Under the plan, the Bank
reviews its profitability and determines what contribution, if any, will be made
to the ESOP. ESOP expense of $197,000, $171,000 and $134,000 was charged to
expense for the years ended December 31, 1997, 1996 and 1995, respectively.

Executive Supplemental Retirement Agreements

The Bank entered into executive supplemental retirement agreements with certain
executive officers. These agreements provide retirement benefits designed to
supplement benefits available through the Bank's retirement plan for employees.
Total expense for benefits payable under the agreements amounted to $101,000,
$78,000 and $73,000 for the years ended December 31, 1997, 1996 and 1995,
respectively. At December 31, 1997, the Bank's liability for these arrangements,
included in accrued expenses and other liabilities, was approximately $387,000.

Director Deferred Compensation Arrangements

Starting in 1983, the Bank entered into deferred compensation arrangements with
certain directors whereby in consideration for the deferral of directors' fees,
those directors will receive in the future a fixed amount of cash compensation.
Expensed under these arrangements for the years ended December 31, 1997, 1996
and 1995 was approximately $220,000, $238,000 and $148,000, respectively. At
December 31, 1997, the Bank's liability for these arrangements, included in
accrued expenses and other liabilities, was approximately $1,768,000.

(13) Estimated Fair Value of Financial Instruments

The following disclosure of the estimated fair value of financial instruments
have been determined by using available quoted market information or other
appropriate valuation methodologies at year-end, and are not indicative of the
fair value of those instruments at the date this report is published. These
estimates do not reflect any premium or discount that could result from offering
for sale at one time the Bank's entire holdings of a particular financial
instrument. Because no market exists for a portion of the Bank's financial
instruments, fair value estimates are based on judgments regarding future
expected loss experience, current economic conditions, risk characteristics of
various financial instruments, and other factors. These estimates are subjective
in nature and involve uncertainties and matters of significant judgment and
therefore cannot be determined with precision. Changes in assumptions could
significantly affect the estimates.

  Fair value estimates are based on existing on- and off-balance sheet financial
instruments without attempting to estimate the value of anticipated future
business and the value of assets and liabilities that are not considered
financial instruments. Significant assets and liabilities that are not
considered financial instruments include real estate acquired by foreclosure,
the deferred income tax asset, office properties and equipment, and core deposit
and other intangibles. In addition, the tax ramifications related to the
realization of the unrealized gains and losses can have a significant effect on
fair value estimates and have not been considered.

  The estimation methodologies used, book values and estimated fair values for
the Bank's financial instruments follows.

Financial instruments actively traded in a secondary market have been valued
using quoted available market prices as follows:

(14) Commitments and Contingencies

Legal Proceedings

The Bank has been named a defendant in various legal proceedings arising in the
normal course of business. In the opinion of management, based on the advice of
legal counsel, the ultimate resolution of these proceedings will not have a
material effect on the Company's or the Bank's consolidated financial
statements.

Off-balance Sheet Risk

The Bank is party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of its customers and to
reduce its own exposure to fluctuations in interest rates. These financial
instruments include commitments to originate or purchase loans, unadvanced
portions of construction loans, unused lines of credit, standby letters of
credit and forward commitments to sell loans. These instruments involve, to
varying degrees, elements of credit and interest rate risk in excess of the
amount recognized in the consolidated balance sheets. The contract or notional
amounts of those instruments reflect the extent of involvement the Bank has in
particular classes of financial instruments.
<PAGE>
 
                   Notes to Consolidated Financial Statement

  The Bank's exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for loan commitments and standby letters of
credit is represented by the contractual amount of those instruments. The Bank
uses the same credit policies in making commitments and conditional obligations
as it does for on-balance sheet instruments. For forward commitments, the
contract or notional amounts do not represent exposure to credit loss. The Bank
controls the credit risk of forward commitments through credit approvals, limits
and monitoring procedures.
 
Financial instruments with off-balance sheet risk are as follows:

</TABLE>

Unused lines of credit, commitments to originate or purchase loans and
unadvanced portions of construction loans are agreements to lend to a customer
provided there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since many of the commitments are expected to
expire without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements. For all lines of credit and loans, the Bank
evaluates each customer's creditworthiness on a case-by-case basis. The amount
of collateral obtained, if deemed necessary by the Bank upon extension of
credit, is based on management's credit evaluation of the borrower.

  Commitments to sell loans are contracts which the Bank enters into for the
purpose of reducing the market risk associated with originating and selling
residential mortgage loans. In order to fulfill the commitment, the Bank must
deliver loans under contract or must pay a cash penalty as determined by the
investor. The Bank does not sell loans with recourse.

  Standby letters of credit are conditional commitments issued by the Bank to
guarantee the performance by a customer to a third party. The credit risk
involved in issuing letters of credit is essentially the same as that involved
in extending loan facilities to customers.

  The Bank is required to maintain certain reserves of vault cash and/or
deposits with the Federal Reserve Bank of Boston. The amount of this reserve
requirement included in cash and due from banks was $1,927,000 at December 31,
1997.

                  Notes to Consolidated Financial Statements

(17) Subsequent Events

     On February 2, 1998, the Company and the Bank entered into a definitive 
agreement under which Compass Bank of New Bedford, Massachusetts will acquire 
Sandwich Bancorp, Inc. Prior to the Company's consideration and approval of its 
definitive agreement with Compass Bank, the Company had contacted and received 
expressions of interest from three other parties who had expressed an interest 
in an acquisition of the Company.

     On February 24, 1998, the Company announced that its Board of Directors, 
consistent with the exercise of its fiduciary duties, determined that it was 
appropriate to request additional information and clarification of the renewed 
expressions of interest that it had received from three other parties subsequent
to February 2.

     Following a comprehensive review of the other expressions of interests for 
the Company, the Company and Compass Bank jointly announced on March 23, 1998, 
that they have signed an amendment to their previously announced agreement of 
February 2, 1998 (the "Amended Agreement") by which Compass Bank would acquire 
Sandwich Bancorp, Inc. Under the terms of the Amended Agreement, Compass Bank's 
parent company, The 1855 Bancorp will convert to a 100% publicly owned stock 
holding company and thereafter issue stock having a value of $64.00 per share to
Sandwich Bancorp shareholders in a tax-free exchange of common stock. The value 
to be received by Sandwich Bancorp shareholders is subject to adjustment 
pursuant to a formula based on the value of the stock of The 1855 Bancorp near 
the transaction date. Based on 1855 Bancorp's assumed initial public offering 
price of $10.00 per share, each Sandwich Bancorp share will be exchanged for 
1855 Bancorp stock having a value of $64.00 per share so long as 1855 Bancorp 
stock trades at an average price of between $10.00 and $13.50 per share during a
designated trading period following the initial public offering date. If this 
average price exceeds $13.50 per share, the value to be received by Sandwich 
Bancorp shareholders will increase proportionately up to a maximum value of
$71.11 until 1855 Bancorp's average price reaches or exceeds $15.00 per share.
If this average price is equal to or less than $10.00 per share, Sandwich
Bancorp shares will be exchanged for 6.4 shares of 1855 Bancorp stock.

     Sandwich Bancorp and The 1855 Bancorp also entered into a Stock Option 
Agreement, granting to The 1855 Bancorp an option to acquire up to 19.9% of 
Sandwich common stock under certain circumstances. The transaction, which is 
subject to all necessary regulatory and shareholder approvals, is expected to 
close in the fourth quarter of 1998.
