(4)  EARNINGS PER SHARE

     Diluted earnings per share for the three months ended March 31, 1999 and
2000 were computed based on the adjusted weighted average number of shares
outstanding during the periods, which amounted to 25,646,690 shares and
24,068,039 shares, respectively. Unallocated ESOP shares and unvested
restricted stock awards are not considered outstanding for purposes of the
computation of earnings per share. There is only an insignificant difference
in the number of shares used in computing basic and diluted earnings per
share and, accordingly, such per share amounts do not differ.

(5)      BUSINESS SEGMENT INFORMATION

       The community banking business segment consists of commercial and
retail banking. This segment is managed as a single strategic unit which
derives its revenues from a wide range of banking services, including
investing and lending activities and acceptance of demand, savings and time
deposits, merchant credit card services as well as servicing loans for
investors. There is no major customer, as defined, and the Bank operates
within a single geographic area (southeastern Massachusetts).

        Non reportable operating segments of the Company's operations which
do not have similar characteristics to the community banking operations and
do not meet the quantitative thresholds requiring disclosure, are included in
the Other category in the disclosure of business segments below. These non
reportable segments include the Parent Company.

(6)      STOCK REPURCHASE PROGRAMS

     In July 1999, the Board of Directors authorized the Company to
repurchase up to 1,000,000 shares in the open market to meet the anticipated
needs of stock awards and stock options issued in connection with the 1999
Stock Incentive Plan. In October 1999, the Board of Directors, with the
approval of the Commissioner of Banks, authorized the Company to repurchase
up to an additional 1,231,900 shares on the open market. The Board of
Directors delegated to the discretion of senior management the authority to
determine the timing of the repurchase programs' commencement, the timing of
the subsequent repurchases and the prices at which repurchases will be made.

     As of May 11, 2000, the Company had  repurchased  2,066,600  shares of
its common stock under these programs at a total cost of $21,696,876 of which
1,859,100  shares at a cost of $19,773,590 had been repurchased as of March
31, 2000.

(7)  QUARTERLY CASH DIVIDEND

     On April 20, 2000, the Board of Directors  voted the payment of a
quarterly cash dividend of $.06 per share.  The dividend is payable on May
19, 2000 to  stockholders  of record on May 5, 2000.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     This Form 10-Q contains certain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. Actual events could differ materially from
those anticipated in the forward-looking statements. Important factors that
might cause such a difference include, among other things, general economic
conditions, particularly the real estate market, in the Company's primary
market area, potential increases in the Company's non-performing assets (as
well as increases in the allowance for loan losses that might be necessary),
concentrations of loans in a particular geographic area or with certain large
borrowers, changes in government regulation and supervision, including
increased deposit insurance premiums or capital or reserve requirements,
changes in interest rates, and increased competition and bank consolidations
in the Company's market area.

COMPARISON OF FINANCIAL CONDITION AT MARCH 31, 2000 AND DECEMBER 31, 1999

     Total assets increased by $87.4 million from $2,122.8 million at
December 31, 1999 to $2,210.2 million at March 31, 2000. During the quarter
ended March 31, 2000, Compass increased its loan portfolio by $87.6 million,
or 5.0%, which was funded principally by deposit growth (primarily
certificates of deposit) of $68.1 million and, to a lesser extent, additional
Federal Home Loan Bank advances of $15.4 million.

     The increase in loans occurred primarily in the residential mortgage,
indirect auto and commercial loan portfolios. From December 31, 1999 to March
31, 2000, residential mortgage loans increased by $40.1 million, or 4.5%,
indirect auto loans (net of unearned discounts) increased by $27.1 million,
or 6.4% and commercial loans (including commercial real estate loans)
increased by $12.1 million, or 4.2%. The growth during the quarter ended
March 31, 2000 is generally attributable to the favorable economic conditions
which prevailed during this period. The Company has continued to retain all
residential mortgage loan originations in portfolio and has continued to
emphasize the origination of indirect auto loans through its network of
automobile dealers which has recently been expanded to include dealers in
communities contiguous to the metropolitan Boston area.

     Total deposits at March 31, 2000 were $1,583.7 million, an increase of
$68.1 million, compared to $1,515.6 million at December 31, 1999. This
increase was largely due to an increase in certificates of deposit of $60.3
million during the quarter. This increase was fueled by the introduction, in
February 2000, of a 7 month certificate at 6.30%. Core deposit account
balances increased by 1% during the quarter. The modest change in core
deposits during the quarter was generally attributable to normal seasonal
fluctuations as well as the shift in funds to higher yielding certificates of
deposit. Management believes that the bank consolidation and divestitures
currently underway in the Bank's market area as a result of the
Fleet/BankBoston merger will peak during the next two quarters offering
Compass a significant opportunity to increase its deposits.

     Total borrowed funds were $331.5 million at March 31, 2000 compared to
$314.6 million at December 31, 1999, an increase of $16.9 million, or 5.4%.
During the quarter ended March 31, 2000, Compass increased its net borrowings
from the Federal Home Loan Bank by $15.8 million in order to fund loan
growth. Management believes that it will continue to expand its Federal Home
Loan Bank borrowings during the remainder of 2000 to partially fund
anticipated loan growth.

     The increase in stockholders' equity of $112,000 to $274.1 million at
March 31, 2000 resulted from the net income of $5.4 million for the quarter
ended March 31, 2000 which was substantially offset by an increase in the
unrealized loss on securities available for sale, cash dividends and stock
repurchases. During 1999, the Company announced two stock repurchase programs
aggregating 2,231,900 shares. As of May 11, 2000, 2,066,600 shares had been
repurchased leaving up to 165,300 shares for repurchase. Management expects
to fully repurchase the remaining shares under these programs during 2000.

COMPARISON OF OPERATING RESULTS FOR THE QUARTERS ENDED MARCH 31, 2000 AND 1999

     Net income was $5.4 million, or $.23 per diluted share, for the quarter
ended March 31, 2000 compared to net income of $5.6 million, or $.22 per diluted
share, for the comparable period in 1999. The 2000 results, as compared to 1999,
include an increase of $1.1 million, or 6.1%, in net interest income, an
increase of $825,000 in the provision for loan losses, an increase of $317,000,
or 17.0%, in non-interest income and an increase of $1.1million, or 10.4%, in
non-interest expense. The Company's effective tax rate declined to 35.3% in 2000
from 36.9% in the comparable 1999 period.

     INTEREST INCOME. Interest income for the quarter ended March 31, 2000 was
$37.4 million, compared to $32.7 million for the quarter ended March 31, 1999,
an increase of $4.7 million, or 14.4%. All of the increase in interest income
resulted from growth in average interest-earning assets of $332.2 million, or
22.9%, as the overall yield on interest-earning assets declined by 4 basis
points in the 2000 period. The principal areas of growth in average balances
were related to real estate loans (up $230.9 million, or 22.9%) and indirect
auto loans (up $103.1 million, or 31.1%). Most of the real estate loan growth
resulted from increased origination and retention in portfolio of one-to-four
family real estate loans. The increase in indirect auto loans resulted from the
positive economic environment within Compass's local markets and the continued
emphasis of this area of lending.

     INTEREST EXPENSE. Interest expense for the quarter ended March 31, 2000 was
$18.4 million compared to $14.9 million for the quarter ended March 31, 1999, an
increase of $3.5 million or 23.5%. This increase resulted from a 19 basis points
increase in the cost of all funds from 4.03% in 1999 to 4.22% in 2000, and a
higher average balance of interest-bearing liabilities (up $271.1 million, or
18.4%). Average interest-bearing deposit balances increased $49.0 million, or
3.6%, during the quarter ended March 31, 2000 compared to the same period in
1999.

     Interest  expense on borrowed funds increased $3.2 million in the
quarter ended March 31, 2000 due to a $222.1 million  increase in the average
balance of such funds, and a 1 basis point increase in the average rate paid
on borrowed funds to 5.79% in the 2000 period.

     PROVISION FOR LOAN LOSSES. Compass provides for loan losses in order to
maintain the allowance for loan losses at a level that management estimates is
appropriate to absorb future chargeoffs of loans deemed uncollectible. In
determining the appropriate level of the allowance for loan losses, management
considers past and anticipated loss experience, evaluations of real estate
collateral, current and anticipated economic conditions, volume and type of
lending and the levels of nonperforming and other classified loans. The amount
of the allowance is based on estimates and ultimate losses may vary from such
estimates. Management assesses the allowance for loan losses on a quarterly
basis and provides for loan losses monthly in order to maintain the adequacy of
the allowance.

     Compass  provided  $1.05 million for loan losses in the quarter ended
March 31, 2000 compared to $225,000 in the quarter ended March 31, 1999.  The
increase of $825,000 in 2000 was primarily attributable to the growth in the
loan portfolio as all indicators of credit quality continue to be positive.

     NON-INTEREST INCOME. Total non-interest income was $2.2 million for the
quarter ended March 31, 2000 compared to $1.9 million in the same period of
1999, an increase of $317,000. This increase was principally caused by increases
in loan fees, debit and ATM card usage and an insurance settlement. Also
non-interest income in the 1999 quarter was adversely impacted by the waiver of
the monthly fee on deposit accounts in the month of conversion of former
Sandwich Bank customers to Compass's computer system.

     NON-INTEREST EXPENSE. Non-interest expense increased by $1.1million, or
10.4%, from $10.6 million for the quarter ended March 31, 1999 to $11.7 million
for the quarter ended March 31, 2000. Of this increase, $1.4 million related to
salaries and employee benefits, which totaled $6.7 million for the quarter ended
March 31, 2000, partially offset by a $294,000 aggregate decrease in all other
categories of non-interest expense.

     Of the increase of $1.4 million in salaries and employee benefits for the
quarter ended March 31, 2000, approximately $500,000 related to increases in the
number of employees and annual wage adjustments, $318,500 was attributable to
the restricted stock awarded in July 1999, employment taxes increased $112,000
and employee-related insurance costs increased $100,000. In addition, the amount
accrued in connection with Compass's management incentive plan increased
$335,000 in 2000 principally due to a reduced expense in the first quarter of
1999 resulting from the utilization of amounts accrued but not paid during the
two month transition period ended December 31, 1998.

                                       10

<PAGE>

     The aggregate decrease in other categories of non-interest expense,
which amounted to $294,000 for the quarter ended March 31, 2000 was primarily
caused by certain non-recurring costs incurred in 1999 attributable to the
merger with Sandwich Bank.

     INCOME TAXES.  The effective tax rate for the quarter ended March 31,
2000 was 35.3% compared to 36.9% in the same period in 1999.  This  reduction
in overall tax rate is due to greater utilization of non-bank subsidiaries
that are taxed at lower rates for state tax purposes.

LIQUIDITY AND CAPITAL RESOURCES

     Compass's liquidity, represented by cash and cash equivalents and debt
securities is a product of its operating, investing, and financing
activities. The Bank's primary sources of funds are deposits, borrowings,
principal and interest payments on outstanding loans and mortgage-backed
securities, maturities of investment securities and funds provided from
operations. While scheduled payments from the amortization of loans and
mortgage related securities and maturing investment securities are relatively
predictable sources of funds, deposit flows and loan prepayments are greatly
influenced by general interest rates and, in the case of deposits, other
instruments available to the public such as mutual funds and annuities.

   As a voluntary member of the Federal Home Loan Bank of Boston (FHLB),
Compass is entitled to borrow an amount up to the value of its qualified
collateral that has not been pledged to others. Qualified collateral
generally consists of residential first mortgage loans, U.S. Government and
Agency securities and funds on deposit at the FHLB. At March 31, 2000,
Compass had approximately $429 million in unused borrowing capacity that is
contingent upon the purchase of additional FHLB stock. Use of this borrowing
capacity may also be impacted by regulatory capital requirements.

   Liquidity management is both a daily and long-term function of business
management. The measure of a bank's liquidity is its ability to meet its cash
commitments at all times with available cash or by conversion of other assets
to cash at a reasonable price. At March 31, 2000, the Company maintained cash
and due from banks, short-term investments and debt securities maturing
within one year of $92.9 million, or 4.20% of total assets. Compass invests
excess funds, if any, in federal funds sold which provides liquidity to meet
lending requirements.

   At March 31, 2000, construction of the Bank's new corporate headquarters
was in-progress. At that date, the estimated remaining construction and
related costs to be incurred were approximately $9.1 million. Compass
believes it has adequate sources of liquidity to fund these costs.

   At March 31, 2000, Compass had commitments to originate loans, unused
outstanding lines of credit, standby letters of credit and undisbursed
proceeds of loans totaling $185.9 million. Compass anticipated that it will
have sufficient funds available to meet its current loan commitments.
Certificates of deposit maturing within one year from March 31, 2000 amounted
to $663.8 million. Compass expects that a significant portion of maturing
certificate accounts will be retained at maturity, although the percentage
retained may be below historical levels due to increased price competition
for these deposits.

   Compass's Tier 1 capital measured 15.5% of risk-weighted assets at March
31, 2000. Total capital, including the Tier 2 allowance for loan losses, was
16.7% of risk weighted assets. The leverage ratio was 10.9%. These ratios
placed Compass in the "well capitalized" category according to regulatory
standards.

   The Company's Tier 1 capital measured 18.2% of risk-weighted assets at
March 31, 2000. Total capital, including the Tier 2 allowance for loan
losses, was 19.4% of risk-weighted assets. The leverage ratio was 12.8%.
These ratios placed the Company in excess of regulatory standards set forth
by the Federal Reserve Board.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The chief market risk factor affecting the financial condition and
operating results of the Company is interest rate risk. This risk is managed
by periodic evaluation of the interest risk inherent in certain balance sheet
accounts, determination of the level of risk considered appropriate given
Compass's capital and liquidity requirements, business strategy, performance
objectives and operating environment and maintenance of such risks within
guidelines approved by the Board of Directors. Through such management,
Compass seeks to reduce the vulnerability of its net earnings to changes in
interest rates. Compass's Asset/Liability Committee, comprised of senior
management, is responsible for managing interest rate risk and reviewing with
the Board of Directors on a quarterly basis its activities and strategies,
the effect of those strategies on Compass's and the Company's operating
results, Compass's interest rate risk position and the effect changes in
interest rates would have on Compass's net interest income. The extent of
movement of interest rates is an uncertainty that could have a negative
impact on the earnings of the Company.

      The principal strategies the Company and Compass generally use to
manage interest rate risk include (i) emphasizing the origination and
retention of adjustable-rate loans, origination of indirect auto loans which
have relatively short maturities and origination of loans with maturities at
least partly matched with those of the deposits and borrowings funding the
loans, (ii) investing in debt securities with relatively short maturities and
(iii) classifying a significant portion of its investment portfolio as
available for sale so as to provide sufficient flexibility in liquidity
management.

     The Company quantifies its interest rate risk exposure using a
sophisticated simulation model. Simulation analysis is used to measure the
exposure of net interest income to changes in interest rates over a specified
time horizon. Simulation analysis involves projecting future interest income
and expense under various rate scenarios. Compass's internal guidelines on
interest rate risk specify that for every 100 basis points immediate shift in
interest rates, its estimated net interest income over the next 12 months
should decline by less than 5%.

     In utilizing a 300 basis point increase in rates in its simulation
model, the full impact of annual rate caps of 200 basis points common to most
adjustable rate mortgage loan products is considered. The rate shocks used
assume an instantaneous and parallel change in interest rates. Prepayment
speeds for loans are based on published median dealer forecasts for each
interest rate scenario.

     As of March 31, 2000, the Company's estimated exposure as a percentage
of estimated net interest income for the next twelve and twenty-four month
periods is as follows:

                                                                        NET INTEREST INCOME OVER:

                                                                      12 MONTHS           24 MONTHS
                                                                      ----------          ---------
<S>                                                                  <C>                <C>
     300 basis point increase in rates..............................   (17.94%)            (17.01%)

     200 basis point decrease in rates..............................     (.23%)             (4.66%)

</TABLE>

     At March 31, 2000, the Company exceeded its internal guidelines for
interest rate risk as set forth above. This occurred as a result of increases
in short-term rates and the greater utilization of shorter term borrowings and
certificates of deposit to fund asset growth. Since Compass began using its
simulation model in 1997, this is the first quarter in which it has exceeded
its internal guidelines for interest rate risk. Management, along with its
professional advisors, will continue to monitor the trend in short-term and
long-term interest rates and the related impact which changes in rates may
have on net interest income.

     Based on the scenario above, net income would be adversely affected in
both the twelve and twenty-four month periods. For each one percentage point
change in net interest income, the effect on net income would be $542,000,
assuming a 36% tax rate.
