             NEW HAMPSHIRE THRIFT BANCSHARES, INC. AND SUBSIDIARY
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
General

  New Hampshire Thrift Bancshares, Inc. (The Company), a Delaware holding
company organized on July 5, 1989, is the parent company of Lake Sunapee Bank,
fsb (The Bank), a federally chartered savings bank.  The Bank is a member of the
Federal Deposit Insurance Corporation (FDIC) and its deposits are insured
through the Savings Association Insurance Fund (SAIF).  The Bank is regulated by
the Office of Thrift Supervision (OTS).

  The Company's profitability is derived from its only subsidiary, Lake Sunapee
Bank, fsb.  The Bank's earnings in turn are generated from the net income from
the yield on its loan and investment portfolios less the cost of its deposit
accounts and borrowings.  These core revenues are supplemented by loan
origination fees, retail banking service fees, gains on the sale of investment
securities, and brokerage fees.  The Bank passes its earnings to the Company to
the extent allowed by OTS regulations.  Current regulations enable the Bank to
pay to the Company the higher of an amount equal to seventy-five per cent of the
Bank's prior four quarter earnings or up to fifty per cent of excess capital
plus total current year earnings.  As of March 31, 1999, the Company had
$1,005,247 available, which it plans to use to continue its annual dividend
payout of $0.64 per share.

Year 2000

  Many companies continue to undertake projects to address the Year 2000 (Y2K).
Companies have determined potential costs and uncertainties based on a number of
factors, including its software and hardware and the nature of its business.
Companies must also coordinate with other entities with which they do business.
Lake Sunapee Bank, through its technology committee and an outside consultant,
implemented many hardware and software changes during 1998, in an effort to
become Y2K compliant.  During 1998, the Bank installed a new data processing
mainframe computer, upgraded its mainframe software, and installed a new proof
of deposit and check imaging system.  All of these Y2K compliant systems were in
operation throughout most of 1998.

  Y2K testing has been on going and will continue throughout 1999.  Based on a
review of internal practices and communications with third party processors, the
Bank does not expect to encounter significant difficulties in connection with
the transition to the Year 2000.  The status of the Bank's `Year 2000 Action
Plan' is reported to its Board of Directors monthly.  A $50,000 annual provision
has been established to cover Y2K related expenses.  In conjunction with the
`Action Plan', the Bank has developed a `Business Continuity Plan'.  This Plan
is designed to allow the Bank to operate should a system it relies on fail.  As
part of the `Business Continuity Plan', the Bank has purchased power generators
and designed a manual accounting system.  It is unlikely the Bank will need to
utilize these systems, but nevertheless, they are developed and being tested.
The Bank is subject to regulatory review concerning the Year 2000 from its
primary regulator, The Office of Thrift Supervision (OTS).  During 1998, the
Bank had both its Phase I and Phase II examinations.  The Bank expects its final
Phase III exam within the next few weeks.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

  Monitoring and managing the Year 2000 project has and will likely continue to
result in additional direct and indirect costs to the Bank.  Direct costs
include potential charges by third party software vendors for product
enhancements, costs involved in testing software for Year 2000 compliance, and
any resulting costs for developing and implementing contingency plans for
critical software products not enhanced.  Indirect costs will principally
consist of the time devoted by existing employees in monitoring software vendor
progress, testing enhanced software products and implementing necessary
contingency plans.  Both direct and indirect costs of addressing the Year 2000
Issue will be charged to earnings as incurred.  Such costs have not been
material to date.

Financial Condition

  During the first three months of 1999, total assets decreased by $5,829,798,
or 1.80% from $323,407,769 to $317,577,971.  Cash and cash equivalents were used
to fund a $4.3 million increase in net portfolio loans and to cover seasonal
deposit outflows of $6.6 million resulting in a reduction in cash and cash
equivalents of approximately $9.9 million during the first three months of 1999.

  Total gross loans increased $4,435,418 from $239,116,440 to $243,551,858, or
1.85%.  During the first quarter of 1999, the Bank originated a record $35.6
million in loans, had pay-offs of approximately $17.6 million, normal
amortization of approximately $3.5 million and loans sold of approximately $13.2
million.  Due to continued favorable fixed interest rates, many of the Bank's
variable rate loan customers refinanced into fixed rate products.  The Bank sold
much of the fixed rate product into the secondary market, retaining the
servicing.  Selling fixed rate loans into the secondary market helps protect the
Bank against interest rate risk and provides the Bank with a consistent fee
income stream.  The proceeds from the sale of loans are then available to lend
back into the Bank's market area and to purchase investment securities.  At
March 31, 1999, the Bank had $137,619,734 in its servicing portfolio.  The Bank
expects to exceed $185 million in serviced loans by the end of 1999.  The Bank
expects to continue to sell fixed rate loans into the secondary market in order
to manage interest rate risk.  Market risk exposure during the production cycle
is managed through the use of secondary market forward commitments.  At March
31, 1999, adjustable rate mortgages comprised approximately 80% of the Bank's
real estate mortgage loan portfolio.  This is consistent with prior years.

  As of March 31, 1999, total investment securities increased slightly by
$24,128, or .04% from $53,755,251 to $53,779,379 (at amortized cost).  During
the first three months of 1999, the Bank purchased approximately $7.0 million of
investment securities to offset the calls and sales of securities that occurred
during that same time.  The Bank continues to use proceeds from sold loans and
paid loans to purchase investment securities in order to increase yields,
thereby mitigating the reduction in the Bank's interest rate spread that might
otherwise occur.  The Bank's net unrealized gain was $415,501 at December 31,
1998 compared to a net unrealized loss of $480,353 at March 31, 1999. This
change of $895,854 reflects the rise in interest rates during the first quarter
and the corresponding decrease in investment security market values.

  Real estate owned and property acquired in settlement of loans increased by
$17,250, or 2.57% to $687,403. This total reflects $315,153 in market value for
the remaining five lots at Blye Hill Landing in Newbury, NH. There were no sales
of real estate property owned, during the first three months of 1999.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

  Deposits decreased by $6,607,441, or 2.34% to $275,441,715 from $282,049,156
at year-end.  Non-interest bearing checking accounts decreased 13.33% as many
business customers settled seasonal transactions. Savings and interest-bearing
checking accounts decreased slightly by .62%.  Certificates of deposit decreased
2.90% as many higher balance customers sought investment alternatives.

  Securities sold under agreement to repurchase decreased by $4,764,024, to
$7,085,092 from $11,849,116. As mentioned above, many business customers settled
seasonal transactions during the first quarter of 1999.  Repurchase agreements
are collateralized by the Bank's government and agency investment securities.

  Overnight and long-term advances from the Federal Home Loan Bank (FHLB)
increased to $3,848,000 from zero at year-end.  During the first three months of
1999, the Bank funded a net $4.2 million increase in loans and an $11.4 million
decrease in deposits and repurchase agreements using approximately $9.9 million
in cash and cash equivalents and $3.8 million from FHLB advances.

  Accrued expenses and other liabilities increased $1,869,622, to $3,599,513
from $1,729,891.  The majority of the increase was attributable to a $1 million
payable recorded for an investment security trade booked at the end of March
that settled in April.

Liquidity and Capital Resources

  The Bank is required to maintain a 4% ratio of liquid assets to net
withdrawable funds.  At March 31, 1999, the Bank's ratio of 9.61% exceeded
regulatory requirements for long-term liquidity.

  The Bank's source of funds comes primarily from net deposit inflows, loan
amortizations, principal pay downs from loans, sold loan proceeds, and advances
from the FHLB.  At March 31, 1999, the Bank had approximately $92,000,000 in
additional borrowing capacity from the FHLB.

  At March 31, 1999, the Company's shareholders' equity totaled $27,603,651, or
8.69% of total assets, compared to $27,779,606, or 8.59% of total assets at
year-end 1998.  The decrease of $175,955 reflects net income of $710,608, the
payment of $336,686 in common stock dividends and the change of $549,877 in the
net unrealized holding gain (loss) on securities classified as available-for-
sale. This change reflects the rise in interest rates during the first three
months of 1999 and the corresponding decrease in investment security market
values during the same period.

  For the three months ended March 31, 1999, net cash provided by operating
activities was $2,268,454, versus $2,149,100 for the same period in 1998.  A net
change in other assets and other liabilities accounted for the majority of the
change as accrued interest, other assets, accrued expenses and other liabilities
increased. A security purchased and booked as a payable at the end of the first
quarter was settled in April.

  Net cash flows used in investing activities amounted to $4,323,077 for the
three months ended March 31, 1999, compared to net cash flows provided by
investing activities of $1,710,628 for the same period in 1998, a change of
approximately $6 million.  A net increase in loans to customers used cash flows
of $4,217,133 compared to a decrease in loans that provided cash flows of
$4,736,593 for the same period in 1998. During the first three months of 1999,
purchases of investment securities were approximately $7.0 million and sales and
calls of investment securities were also $7.0 million.  Investment security
activity during the first quarter of 1998 used net cash flows of approximately
$3.4 million.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

  At March 31, 1999, net cash flows used in financing activities was $7,860,151
compared to net cash provided by financing activities of $955,760 for the same
period in 1998, a change of approximately $8.8 million.  A decrease in deposits
and repurchase agreements of $11,371,465 was partially offset by an increase in
advances from the FHLB and other borrowings of $3,848,000.  During the same time
period in 1998, deposits and repurchase agreements increased $1,610,863 while
FHLB advances decreased $369,160.

  The Bank expects to be able to fund loan demand and other investing during
1999 by continuing to use funds provided from customer deposits, as well as the
FHLB's advance program.  Management is not aware of any trends, events, or
uncertainties that will have or that are reasonably likely to have a material
effect in the Company's liquidity, capital resources or results of operations.

  Banks are required to maintain tangible capital, core leverage capital, and
total risk based capital of 1.50%, 4.00%, and 8.00%, respectively.  As of March
31, 1999, the Bank's ratios were 7.32%, 7.32%, and 12.32%, respectively, well in
excess of the regulators' requirements.

  Book value per share was $13.12 at March 31, 1999, versus $12.41 per share at
March 31, 1998.  The increase in paid-in capital and retained earnings provided
the increase in book value per share.

Interest Rate Sensitivity

  The principal objective of the Bank's interest rate management function is to
evaluate the interest rate risk inherent in certain balance sheet accounts and
determine the appropriate level of risk given the Bank's business strategies,
operating environment, capital and liquidity requirements and performance
objectives and to manage the risk consistent with the Board of Directors'
approved guidelines.  The Bank's Board of Directors has established an
Asset/Liability Committee (ALCO) to review its asset/liability policies and
interest rate position monthly.  Trends and interest rate positions are reported
to the Board of Directors quarterly.

  Gap analysis is used to examine the extent to which assets and liabilities are
"rate sensitive".  An asset or liability is said to be interest rate sensitive
within a specific time-period if it will mature or reprice within that time.
The interest rate sensitivity gap is defined as the difference between the
amount of interest-earning assets maturing or repricing within a specified
period of time and the amount of interest-bearing liabilities maturing or
repricing within the same specified period of time.  The strategy of matching
rate sensitive assets with similar liabilities stabilizes profitability during
periods of interest rate fluctuations.

  The Bank's one-year gap at March 31, 1999, was 6.42%, compared to the December
31, 1998 gap of 6.78%.  The Bank continues to hold in portfolio adjustable rate
mortgages, which reprice at one, three, and five-year intervals.  The Bank sells
fixed-rate mortgages into the secondary market in order to minimize interest
rate risk.

  The Bank's gap, of approximately negative six percent at March 31, 1999, means
net interest income would increase if interest rates trended downward.  The
opposite would occur if interest rates were to rise.  Management feels that
maintaining the gap within ten points of the parity line provides adequate
protection against severe interest rate swings.  In an effort to maintain the
gap within ten points of parity, the Bank may utilize the FHLB advance program
to control the repricing of a segment of liabilities.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

  As another part of its interest rate risk analysis, the Bank uses an interest
rate sensitivity model, which generates estimates of the change in the Bank's
net portfolio value (NPV) over a range of interest rate scenarios.  The OTS
produces the data quarterly using its own model and data submitted by the Bank.

  NPV is the present value of expected cash flows from assets, liabilities and
off-balance sheet contracts.  The NPV ratio, under any rate scenario, is defined
as the NPV in that scenario divided by the market value of assets in the same
scenario.  Modeling changes requires making certain assumptions, which may or
may not reflect the manner in which actual yields and costs respond to the
changes in market interest rates.  In this regard, the NPV model assumes that
the composition of the Bank's interest sensitive assets and liabilities existing
at the beginning of a period remain constant over the period being measured and
that a particular change in interest rates is reflected uniformly across the
yield curve.  Accordingly, although the NPV measurements and net interest income
models provide an indication of the Bank's interest rate risk exposure at a
particular point in time, such measurements are not intended to and do not
provide a precise forecast of the effect of changes in market rates on the
Bank's net interest income and will likely differ from actual results.


The following table sets forth the Bank's NPV as of December 31, 1998 (the
latest NPV analysis prepared by the OTS), as calculated by the OTS.

Allowance for Loan Losses and Asset Quality

  The Bank considers many factors in determining the allowance for loan losses.
These include the risk and size characteristics of loans, the prior years' loss
experience, the levels of delinquencies, the prevailing economic conditions, the
number of foreclosures, unemployment rates, interest rates, and the value of
collateral securing the loans.  No changes were made to the Bank's procedures
with respect to maintaining the loan loss allowances as a result of any
regulatory examinations.

  Additionally, the Bank's commercial loan officers review the financial
condition of commercial loan customers on a regular basis and perform visual
inspections of facilities and inventories.  The Bank also has an internal audit
and compliance program.  Results of the audit and compliance programs are
reported directly to the Audit Committee of the Bank's Board of Directors.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

     The allowance for loan losses at March 31, 1999 was $3,149,129, compared to
$3,117,068 at year-end 1998.  As of March 31, 1999, the allowance included
$2,763,435 in general reserves compared to $2,731,484 at year-end 1998. The
total allowance represented 1.29% of total loans at March 31, 1999 versus 1.30%
at year-end 1998. The allowance for loan losses as a percentage of non-
performing assets was 103.69% at March 31, 1999, compared to 115.82% at December
31, 1998.  During the first three months of 1999, the Bank had net charge-offs
of $117 compared to $34,833 for the same period in 1998.

  Loans classified for regulatory purposes as loss, doubtful, substandard or
special mention do not result from trends or uncertainties which the Bank
reasonably expects will materially impact future operating results, liquidity,
or capital resources.  As of March 31, 1999, there were no other loans not
included in the table below or discussed where known information about the
possible credit problems of borrowers caused management to have doubts as to the
ability of the borrower to comply with present loan repayment terms and which
may result in disclosure of such loans in the future.

  Total classified loans, excluding special mention, as of March 31, 1999 were
$5,198,223 compared to $5,356,046 at December 31, 1998. At March 31, 1999, loans
classified as 90 days delinquent were $1,290,849 compared to $170,999 at
December 31, 1998.   At March 31, 1999, non-earning assets were $1,058,999
compared to $1,850,214 at year-end 1998. Total non-performing assets amounted to
$3,037,251 and $2,691,366, for March 31, 1999 and December 31, 1998,
respectively.

The following table shows the breakdown of non-performing assets and non-
performing assets as a percentage of total assets (dollars in thousands):

           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

Results of Operations

  Net income for the three months ended March 31, 1999, was $710,608, or $0.34
per common share (assuming dilution) compared to $702,826, or $0.33 per common
share (assuming dilution) for the same period in 1998.

     Net interest income increased $96,940, or 3.52%, from $2,751,971 for the
first three months of 1998 to $2,848,911 for the first three months of 1999.
The increase was due primarily to a decrease in the cost of deposits and a
decrease in the average outstanding balance of FHLB advances.

  Total interest income for the quarter ended March 31, 1999 decreased by
$281,055, or 4.83%, to $5,533,268 from $5,814,323 for the same period in 1998.
For the three months ended March 31, 1999, interest on loans decreased $613,660,
or 11.74% to $4,614,301 from $5,227,961 for the same period in 1998.  Total
loans held in portfolio decreased from $250,582,342 at March 31, 1998 to
$243,551,858 at March 31, 1999.  The decrease in loan interest income was
primarily attributable to lower yields on loans and a decrease in loans held in
portfolio.  As customers refinanced from variable rate into fixed rate loans,
the Bank sold the loans into the secondary market in order to reduce interest
rate risk.  Fee income associated with the sales is recorded in other income.
Somewhat offsetting the decrease in interest on loans, was a $332,605 increase
in interest and dividends on investments.  As mentioned above, proceeds from
sold loans may be used to purchase investment securities.  Total investment
securities, including federal funds,  increased $6,076,436 from $47,222,590 at
March 31, 1998 to $53,299,026 for the same period in 1999.

  For the three months ended March 31, 1999, total interest expense decreased
$377,995, or 12.34%.  The decrease was a result of lower interest expense
associated with deposits and FHLB advances.  Higher balances in transaction-type
accounts and lower balances in certificates of deposit accounts reduced the
Bank's cost of deposits to 3.81% at March 31, 1999 from 4.27% for the same
period in 1998.  At March 31, 1999, advances from FHLB and other borrowed funds
totaled $3,848,000 compared to $10,177,158 for the same period in 1998.  During
the same period, the Bank's cost of advances fell to 4.05% from 4.33%.

     Due to lower loan portfolio balances combined with management's assessment
that reserve levels are adequate, the provision for loan losses remained
consistent with 1998 levels.  As of March 31, 1999, the net provision for loan
losses totaled $30,000 compared to $14,520 for the same period in 1998.  The
total allowance represented 1.29% of total loans at March 31, 1999 versus 1.20%
for the same period in 1998.

  For the quarter ended March 31, 1999, total other income increased by
$222,807, or 57.01% from $390,822 in 1998 to $613,629 for the same period in
1999.  The change was primarily a result of a $133,992, or 49.07% increase in
loan origination and customer service fees.  In addition, net gains on the sale
of loans accounted for $47,873 of the increase.  As mentioned above, the Bank
originated a record $35.6 million of loans during the first quarter compared to
$26.9 for the same period in 1998 and sold $13.1 million.

  Total operating expenses increased $312,437, or 14.95% for the three months
ended March 31, 1999. Additional staffing and occupancy costs were realized as
the Bank managed its increased loan volume through increased staffing and
outsourcing.  The Bank also recorded additional depreciation expense associated
with system upgrades done throughout 1998.

                        Independent Accountants' Report
                        -------------------------------

We have reviewed the accompanying consolidated statement of financial condition
of New Hampshire Thrift Bancshares, Inc. and Subsidiary as of March 31, 1999,
and the related consolidated statements of income and cash flows for the three-
month period then ended. These consolidated financial statements are the
responsibility of the company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquires of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the consolidated statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should 
be made to the accompanying consolidated financial statements for them to be in 
conformity with generally accepted accounting principles.

                                  Article II

                                The Acquisition


     2.1   The Acquisition. As promptly as practicable following the
satisfaction or waiver of the conditions to the parties' respective obligations
hereunder, and subject to the terms and conditions of this Agreement, as of the
Effective Time, Parent shall transfer to Purchaser all of its right title and
interest in and to the Target Stock Outstanding, free and clear of any liens,
claims, encumbrances, charges, pledges, restrictions or rights of third parties
of any kind whatsoever ("Liens") in exchange for the Purchase Price.

     2.2   Effective Time. The Acquisition shall be effected by the transfer of
the Target Stock Outstanding as contemplated by Section 2.1 at the closing (the
"Closing") on the day ("Closing Date") provided for in Article XI hereof. The
term "Effective Time" shall mean the time on the Closing Date (or a subsequent
date not later than the opening of business on the next business day) when the
Acquisition becomes effective as agreed to by the parties at the Closing.

     2.3   Purchase Price  

           2.3.1.  On the Closing Date, Purchaser shall pay to, or to the order
of, Parent by wire transfer in immediately available funds in U.S. dollars an
aggregate amount equal to $30.6 million (as hereinafter adjusted, the "Purchase
Price") to an account designated by Parent in writing.

           2.3.2.  The Purchase Price shall be adjusted as follows: (i) if Trust
Business revenues reflected in the December 31, 1998 financial statements ("1998
Trust Revenues") of Target exceed by more than 5 percent the annualized Trust
Business revenues ("Closing Trust Revenues") generated for the period commencing
ninety (90) days prior to the third business day prior to the Closing Date and
ending on the third business day prior to the Closing Date, then the Purchase
Price shall be reduced by an amount equal to two (2) times the difference
between such 1998 Trust Revenues and the Closing Trust Revenues, provided,
however, that there shall be no adjustment in the Purchase Price for any loss of
Trust Revenues up to an amount equal to 5% of 1998 Trust Revenues that is
directly attributable to a general decline in the securities markets; (ii) if
the aggregate balance of deposit accounts of Target outstanding as of December
31, 1998, as reflected in the December 31, 1998 financial statements ("1998
Deposit Balances") of Target, exceed by more than 5 percent the aggregate
average balance of deposit accounts ("Closing Deposit Balances") for the period
(the "Deposit Measurement Period") commencing thirty (30) days prior to the
third business day prior to the Closing Date and ending on such third business
day prior to the Closing Date, the Purchase Price shall be reduced by an amount
(the "Deposit Reduction Amount") equal to the product of (A) 9.4% and (B) the
difference between the 1998 Deposit Balances and the Closing Deposit Balances;
and (iii) if annualized Closing Trust Revenues exceed by more than 5 percent the
annualized Trust Business revenues generated in the six (6) month period
following the Closing Date ("Post-Closing Trust Revenues"), then the Purchase
Price shall be reduced by an amount equal to two (2) times the difference
between the Closing Trust Revenues and the Post-Closing Trust Revenues (the
"Trust Revenue Reduction Amount"), and Parent will pay the Trust Revenue
Reduction Amount, if any, to 

                                       6
<PAGE>
 
Purchaser promptly after the sixth month anniversary of the Closing Date.

     If any portion of the Deposit Measurement Period falls within the period
from December 15, 1999 to December 31, 1999, the parties agree that reductions
in deposit balances may be temporary and attributable to customer nervousness
over the Y2K issue.  In such event, Parent may elect, in lieu of calculating or
paying a Deposit Reduction Amount, if any, in accordance with the preceding
paragraph, to calculate a Post-Closing Deposit Reduction Amount, if any, as
follows.  If the 1998 Deposit Balances exceed by more than 12.5 percent the
aggregate average deposit account balances ("March Deposit Balances") on
accounts that were transferred to Purchaser at the Closing for the period (the
"Y2K Deposit Measurement Period") commencing on March 1, 2000 and ending on
March 31, 2000, the Purchase Price shall be reduced by an amount (the "Post-
Closing Deposit Reduction Amount") equal to the product of (A) 9.4% and (B) the
difference between the 1998 Deposit Balances and the March Deposit Balances.
Parent will pay the Post-Closing Deposit Reduction Amount, if any, to Purchaser
promptly after March 31, 2000.  Deposit balances transferred by former Branch
Customers from a transferred account at one Bank Party to an account at another
Bank Party or to another account at a Bank Party shall be included in all
calculations of March Deposit Balances.

        2.2.3. Notwithstanding any other provision of this Agreement,

           (a)  there shall be no adjustment in the Purchase Price to the extent
     that such reduction represents a depositor's transfer (direct or indirect)
     of deposit liabilities from Target to a Bank Party or any Affiliate or a
     client's transfer of Trust Business from Target to Purchaser or an
     Affiliate of Purchaser, in each case between the date of this Agreement and
     the last day of the applicable deposit or Trust Revenues measurement
     period;

           (b)  there shall be no adjustment in the Purchase Price based upon
     differences in annualized Trust Revenues if Purchaser shall not have been
     in material compliance with the requirements of Section 2.8;

           (c)  if Parent shall have closed the Parent Accounts upon the request
     of Purchaser (as provided in Section 6.16), the aggregate amount of deposit
     balances in the Parent Accounts as of December 31, 1998 ("Parent 1998
     Balances") shall not be taken into account in calculating the 1998 Deposit
     Balances. Accordingly, under such circumstances the 1998 Deposit Balances
     shall be calculated after deducting (X) the Parent 1998 Balances from (Y)
     the aggregate amount of deposit balances reflected in the December 31, 1998
     financial statements of Target;

           (d)  as to the Trust Revenue Reduction Amount only, all calculations
     of annualized Trust Revenues shall be prepared after adjusting the fee
     percentages applicable to accounts and market values of all securities on
     which fee income is calculated so that such fee percentages and market
     values are identical for each of the two measurement periods.

        2.3.4. In the event that the Effective Time has not occurred on or prior
to the eight month anniversary of the date of this Agreement, and the failure of
the Effective Time to have occurred on or prior to such anniversary is not
attributable to acts or omissions by Target or Parent, then the Purchase Price
shall be adjusted upwards by an amount determined by (a) multiplying (1) the
originally agreed upon Purchase Price by (2) a percentage interest rate
determined for the period commencing on the day after such eight-month
anniversary date through and

                                       7
<PAGE>
 
including the Closing 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 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.

     2.4   Accounting as of Effective Time; Proration. Seven (7) business days
prior to the Closing Date, Deloitte and Touche, independent certified
accountants with respect to Target, will deliver to Purchaser an estimated
balance sheet ("Estimated Balance Sheet") of Target as of the Closing Date,
prepared as provided in Section 2.5. Except to the extent otherwise provided in
Section 2.5, such Estimated Balance Sheet shall be prepared on a basis
consistent with Target's December 31, 1998, financial statements and in
accordance with GAAP as though the Closing Date were the end of a fiscal year
(and reviewed in accordance with Statements on Standards for Accounting and
Review Services issued by the American Institute of Certified Public Accountants
by Deloitte and Touche). Except to the extent otherwise provided in Section 2.5,
items of income and expense attributable to the period prior to the Closing
shall be allocated to Target and the Estimated Balance Sheet shall be prepared
taking such allocations into account, and items of income and expense
attributable to the period after the Closing shall be allocated to Target for
periods thereafter. Except to the extent otherwise provided in Section 2.5, such
items of income and expense (including all Taxes) shall be prorated on an
estimated basis as of the close of business on the Closing Date, and reflected
on the Estimated Balance Sheet as of the Closing Date, whether or not such
adjustment would normally be made as of such time. Items of proration not
capable of being settled at Closing shall be settled not later than thirty (30)
days after Closing unless otherwise agreed by the parties hereto, and reflected,
together with any other adjustments agreed to by Purchaser and Parent, in a
final balance sheet to be prepared by Deloitte and Touche on behalf of Target
delivered to Purchaser and Parent on the 30th day following Closing (the "Final
Balance Sheet"). Unless Purchaser or Parent objects to the Final Balance Sheet
calculation, the Closing Dividend shall be recalculated based on the Final
Balance Sheet and Parent or Purchaser, as the case may be, shall promptly pay
the amount due to the other party by wire transfer in immediately available
funds in U.S. dollars to such account as such other party shall advise. If
either Purchaser or Parent objects to any element of the calculation of the
Final Balance Sheet provided in this Section 2.4, such objecting Party shall
notify the other of its objection and the basis therefor in the form of written
advice by a certified public accountant of its choosing ("Parent CPA" or
"Purchaser CPA", as the case may be). If such objections are not resolved within
15 days, Purchaser CPA and Parent CPA, as applicable, shall designate an
independent certified public accountant to resolve the matter and such
accountant's determination shall be binding on Purchaser and Parent. The fees of
Deloitte and Touche in preparing the Estimated Balance Sheet and the Final
Balance Sheet and the fees of any independent certified public accountant
designated to resolve any objections with respect to the Final Balance Sheet
shall be shared equally by Parent and Purchaser.

     2.5.  Adjustments to Target's Books as of Closing Date. Notwithstanding any
other provisions of this Agreement, and regardless of the requirements of GAAP,
in preparing Target's financial statements as of the Closing Date (and in
preparing the Estimated Balance Sheet and the Final Balance Sheet), the
following provisions shall apply:

                                       8
<PAGE>
 
     2.5.1.  No adjustment shall be made in Target's book value for any real
property of Target;

     2.5.2.  All securities in Target's investment portfolio will be carried at
values equal to their fair market value;

     2.5.3.  All goodwill, all sold mortgage servicing intangibles, and all
other intangibles shall have been written off to zero (it being understood that
the so-called "deferred tax asset" does not constitute goodwill or an
intangible).

     2.5.4.  It is the intention of the parties that the Estimated Balance Sheet
and the Final Balance Sheet be prepared, to the extent possible, as if the
Closing Date were the end of a fiscal year.  Accordingly, to the extent accruals
are not normally made as of the close of a fiscal year for recurring expenses
(such as rent and utility bills), no accruals shall be made for such types of
items in preparation of the Estimated Balance Sheet or the Final Balance Sheet;

     2.5.5.  Purchaser has agreed to be responsible for "stay for pay"
arrangements with key employees of Target in an amount not to exceed $200,000 in
the aggregate (as described in Section 6.2.2), and the full amount of such stay
for pay arrangements (up to such maximum) shall be an expense allocated to and
payable by Purchaser (and, accordingly, not accrued on the Estimated Balance
Sheet or the Final Balance Sheet);

     2.5.6.  Purchaser shall be responsible for the costs of terminating any
agreements or contracts that it or a Bank Party may choose to terminate in
connection with the transactions contemplated by this Agreement, and the full
amount of any charges or expense payable in connection with any such
terminations shall be an expense allocated to and payable by Purchaser or a Bank
Party, as the case may be (and, accordingly, not accrued on the Estimated
Balance Sheet or the Final Balance Sheet);

     2.5.7.  Target shall have sold or transferred all mortgage and other Loan
servicing rights (other than those relating to Loans retained in Target's Loan
portfolio) and all collateralized mortgage obligations of Target; and

     2.5.8   Purchaser agrees to accept all of Target's accounting principles,
practices and procedures to the extent they are consistent with GAAP and
Target's prior accounting practices, including, but not limited to, valuation of
assets and determination of liabilities, reserves for bad debts, inventory
valuations, fixed asset accounting and record keeping, methods and lives of
depreciation and capitalization policies; provided, however, that Target shall
not alter its loan loss reserve methodologies and shall maintain its loan loss
reserves at levels consistent with those reflected in the December 31, 1998
audited financial statements of Target.

  2.6.Solicitation of Trust Business.  Prior to the Closing Date, neither
Purchaser nor any Bank Party nor any of their Affiliates shall solicit customers
of the Target Offices ("Branch Customers") through advertising specifically
referencing or targeted to such Branch Customers in a way which is reasonably
likely to induce such Branch Customers to close Trust accounts or would
otherwise result in the transfer of all or a portion of existing Trust Business
or Bank Business from Target. Notwithstanding the foregoing sentence, Purchaser,
the Bank Parties, and their respective Affiliates shall be permitted, subject to
the provisions of Section 6.13.3, to (a) engage in advertising, solicitations or
marketing campaigns not primarily directed to or targeted at Target Customers,
(b) respond to unsolicited inquiries by Branch Customers with respect to Trust
services, and (c) provide notices or communications relating to the transactions
contem-

                                       9
<PAGE>
 
plated hereby in accordance with the provisions hereof.

     2.7   Solicitation of Deposit Accounts. Prior to the Closing Date, neither
Purchaser nor any Bank Party nor any of their Affiliates shall solicit Branch
Customers through advertising specifically referencing or targeted to such
Branch Customers in a way which is reasonably likely to induce such Branch
Customers to close deposit liability accounts or open accounts with any Bank
Party or would otherwise result in the transfer of all or a portion of an
existing deposit liability from Target. Notwithstanding the foregoing sentence,
Purchaser, the Bank Parties, and their respective Affiliates shall be permitted,
subject to the provisions of Section 6.13.3, to (a) engage in advertising,
solicitations or marketing campaigns not primarily directed to or targeted at
Target Customers, (b) respond to unsolicited inquiries by Target Office
Customers with respect to banking or other financial services, and (c) provide
notices or communications relating to the transactions contemplated hereby in
accordance with the provisions hereof.

     2.8   Administration of Trust Business. During the six month period
following the Closing Date, Purchaser will operate the Trust Business, and it
will cause each of the Purchaser Subsidiaries to operate its Trust Business,
only in the usual, regular and ordinary course of business, use commercially
reasonable efforts to preserve intact the Trust Business and assets, and
maintain its rights and franchises and fee income; and except as disclosed on
Schedule 2.8, take no action which could reasonably be expected to adversely
affect the Trust Business or the fee income generated by such Trust Business.

     2.9   Payment of Closing Dividend. On the Closing Date, Target shall
transfer the "Closing Dividend" to Parent. The Closing Dividend shall be an
amount equal to (A) the total equity of Target as reflected on the Estimated
Balance Sheet (after making the adjustments described in Section 2.5) plus (B)

Target Subsidiary, as applicable, owns fee title (or leasehold title in the case
of the so-called Shopping Center Branch, Newport Road, New London, New
Hampshire) in and to the real property free of material encumbrances, Liens and

     2.11    Possible Alternative Structures. Notwithstanding anything to the
contrary contained in this Agreement, prior to the Effective Time, Purchaser may
(with the permission of Parent, which permission shall not be unreasonably
withheld or delayed) revise the structure of the Acquisition and the other
transactions contemplated hereby and thereby (including to effect the indirect
acquisition of Target by the acquisition of a mid-tier holding company the
capital stock of which is owned 100% by Parent, and which mid-tier holding
company owns 100% of the outstanding stock of Target ("Holding Company");
provided, however, that provisions hereof which refer to "Target" shall be
deemed modified, as appropriate, to refer to "Target" and "Holding Company."
Notwithstanding the foregoing, any modification of the structure of the
Acquisition (which currently contemplates a Section 338(h)(10) election) may be
effected only if (i) Purchaser reimburses Parent (on a "grossed-up" basis) for
any increase in the aggregate Taxes of Parent, Target (to the extent paid by
Parent), and their stockholders as a result of the modification and in excess of
the Taxes that would be due under the structure provided in this Agreement prior
to such modification pursuant to this Section 2.11; (ii) the consideration to be
paid to the direct or indirect holders of Target Common Stock under this
Agreement is not thereby changed in kind or reduced in amount; (iii) there are
no material adverse changes to the benefits and other arrangements provided to
or on behalf of Target's directors, officers and other employees; (iv) such
modification will not be likely to delay materially or jeopardize receipt of any
required regulatory approvals or other consents and approvals relating to the
consummation of the Acquisition; and (v) Purchaser reimburses Target for any
costs (including without limitation the cost of preparing any necessary
regulatory application) incurred as a result of such modification. Purchaser and
Target agree to appropriately amend this Agreement and any related documents as
necessary in order to reflect any such revised structure.

of the parties to this Agreement agrees to provide to each other party, and to

reflecting transfers of deposit balances or Trust Business) as may from time to
time be in its possession and may be reasonably requested by a party in order to
determine amounts payable or receivable by a party under this Agreement.

such party's covenants contained in Articles VI and VII; provided, however, that

would have a Material Adverse Effect (as defined herein) with respect to either
Target or Purchaser, respectively, unless otherwise stated in a specific
representation, warranty or schedule.

court, or in default under 

                                      18
<PAGE>
 
any order, license, regulation or demand of any governmental agency, and in the
past three years neither Target nor any Target Subsidiary has received notice of
a violation or alleged violation of any statute, ordinance, order, rule or
regulation. Neither Target nor any Target Subsidiary is subject to 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 none of them has
received any written communication requesting that it enter into any of the
foregoing. No regulatory agency has initiated any proceeding or, to the best
knowledge of Target and Parent after due inquiry by Target, investigation into
the business or operations of Target or any of the Target Subsidiaries since
December 31, 1996. Target has not received any objection from any regulatory
agency to Target's response to any violation, criticism or exception with
respect to any report or statement relating to any examinations of Target or any
of the Target Subsidiaries. Except as disclosed on Schedule 4.15, Target is
administering all Trusts in all material respects in accordance with customary
and usual standards of fiduciary responsibility, applicable law, and the
governing provisions of all applicable agreements, instruments, and documents
and any amendments thereto.

     4.15.3. To Parent's and Target's knowledge, the operation of the Target
Offices has been and is being conducted in accordance with all applicable laws,
rules and regulations of all authorities the penalty or liability for the
violation of which, if imposed or asserted, could reasonably be expected to have
a Material Adverse Effect on Parent, Target, or any Branch Subset.

     4.15.4. Target satisfies all requirements to be considered a qualified
thrift lender under HOLA.

   4.16 Employee Benefit Plans

     4.16.1. Schedule 4.16.1 describes 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, fringe or employee benefit plan or agreement
maintained for the benefit of employees or former employees of Target or any
Target Subsidiary at any time during the six-year period ending on the Closing
Date (the "Target Employee Plans"), whether written or oral, and Target has
previously furnished or made available to Purchaser accurate and complete copies
of the same together with (i) the three (3) most recent actuarial and financial
reports prepared with respect to any qualified plans, (ii) the three (3) most
recent annual reports filed with any governmental agency, (iii) all rulings and
determination letters and any open requests for rulings or letters that pertain
to any qualified plan, and (4) the summary plan description or other employee
communications relating thereto.

     4.16.2. None of Target, any Target Subsidiary, any pension plan maintained
by either of them and intended to be qualified under Section 401 of the Code or,
to the best of Target'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 Target or any Target Subsidiary.

     4.16.3. Except as set forth in Schedule 4.16.3, neither Target nor any
Target Subsidiary (i) has ever participated 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), or (ii) has ever provided
health care or other non-pension benefits to any employees 

                                      19
<PAGE>
 
after their employment is terminated (other than as required by part 6 of
subtitle B of title I of ERISA) or has ever promised to provide such post-
termination benefits.

     4.16.4. Except as set forth in Schedule 4.16.4, a favorable determination
letter has been issued by the Internal Revenue Service with respect to each
Target Employee Plan which is an "employee pension benefit plan" (as defined in
Section 3(2) of ERISA) (a "Target 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 Target's and Parent's knowledge, is threatened to be revoked.

     4.16.5. Except as set forth in Schedule 4.16.5, to the best of Target's and
Parent'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 Target Employee Plan
which would result in the imposition, directly or indirectly, of an excise tax
under Section 4975 of the Code.

     4.16.6. 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 Target Employee
Plan or ERISA; 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 Target Pension Plan, and there is no "unfunded current liability" (as
defined in Section 412 of the Code) with respect to any Target Pension Plan.
With respect to any Target Employee Plan subject to Title IV of ERISA, there has
been no (nor will there be any as a result of the sale by Parent of the Target
Stock Outstanding) (i) "reportable event," within the meaning of ERISA Section
4043 or the regulations thereunder, for which the notice requirement is not
waived by the regulations thereunder, and (ii) event or condition which presents
a material risk of a plan termination or any other event that is reasonably
likely to cause the Target or any Target Subsidiary to incur liability or have a
Lien imposed on its assets under Title IV of ERISA. No Target Employee Plan
subject to Title IV of ERISA has any "unfunded benefit liabilities" within the
meaning of ERISA Section 4001(a)(18), as of the Closing Date. Neither Target nor
any Target Subsidiary has ever maintained a multiemployer plan (within the
meaning of Section 4001(a)(3) of ERISA). Except as may be provided in the
applicable Plan document or in Schedule 4.16.6, no withdrawal, termination or
other liability would be incurred as a result of Target's or Target Subsidiary's
termination of, or a cessation of participation in, any Target Employee Plan as
of the Closing Date, including, without limitation, liability under Section 4063
of ERISA. Each Target Employee Plan has complied with the notification and other
applicable requirements of the Consolidated Omnibus Budget Reconciliation Act of
1985, Health Insurance Portability and Accountability Act of 1996, the Newborns'
and Mothers' Health Protection Act of 1996, and the Mental Health Parity Act of
1996.

     4.16.7. Except as disclosed in Schedule 4.16.7 or 4.16.5, to the best of
Target's and Parent's knowledge, the Target 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.

                                      20
<PAGE>
 
     4.16.8. Each Target Employee Plan may be amended, terminated, or otherwise
modified by Target to the greatest extent permitted by applicable law, including
the elimination of any and all future benefit accruals under any Target Employee
Plan, and no employee communication has limited the right of the Target or any
Target Subsidiary to so amend, terminate or otherwise modify such Target
Employee Plan.

   4.17 Certain Contracts

     4.17.1. Except as disclosed in Schedule 4.17, neither Target nor any Target
Subsidiary is a party to, is bound or affected by, receives, or is obligated to

     securities sold under agreements to repurchase in the ordinary course of
     business) or the guarantee by Target or any Target Subsidiary of any
     obligation, other than by Target or any Target Subsidiary in the ordinary

     Subsidiary upon execution of this Agreement or upon or following sale by
     Parent of the Target Stock Outstanding (either alone or in connection with
     the occurrence of any additional acts or events);

         (c) any agreement, arrangement or understanding pursuant to which
     Target or any Target Subsidiary is obligated to indemnify any current or
     former director, officer, employee or agent of Target or any Target
     Subsidiary;

         (d) any agreement, arrangement or understanding to which Target or any
     Target Subsidiary is a party or by which any of the same is bound which
     limits the freedom of Target or any Target Subsidiary to compete in any
     line of business or with any Person,

         (e) any assistance agreement, supervisory agreement, memorandum of
     understanding, consent order, cease and desist order or condition of any

     the provision of banking services entered into by any Target Subsidiary in
     the ordinary course of business) that involves a payment or series of
     payments of more than $100,000 in the aggregate from or to Target or any
     Target Subsidiary (unless such agreement is cancellable by Target upon
     payment of a termination fee of not more than $100,000 in the aggregate).

     4.17.2. Neither Target nor any Target Subsidiary is in material default or
non-compliance under any material 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.

                                      21
<PAGE>
 
   4.18 Brokers and Finders Except as disclosed in Schedule 4.18, neither Target
nor any Target Subsidiary nor any of their respective directors, officers or
employees, has employed any broker or finder or incurred any liability for any
broker or finder fees or commissions in connection with the transactions
contemplated hereby.

   4.19 Insurance. Target has disclosed in Schedule 4.19 all policies of
insurance maintained by it or any Target Subsidiary as of the date hereof and
any claims thereunder in excess of $50,000 since January 1, 1997. Said insurance
is sufficient for compliance by each of them with all requirements of law and
all agreements and leases to which each of them is a party and to conduct
business as it is currently being conducted. Neither Target nor any Target
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 prior to the Effective Time or, except as disclosed on
Schedule 4.19, that such policies cannot be continued by Purchaser or any
successor to Purchaser after the Effective Time. In addition, Target has all
ERISA bonds necessary for it to continue to conduct its business as historically
conducted.

   4.20 Loans. Except as disclosed in Schedule 4.20, neither Target nor any of
its Subsidiaries is a party to any written or oral (a) loan agreement, note or
borrowing arrangement (including, without limitation, leases and credit
enhancements) (collectively, "Loans") the unpaid principal balance of which
exceeds $25,000 and as to which the obligor is, as of December 31, 1998, over 90
days delinquent in payment of principal or interest, or (b) Loan with any
director, executive officer or affiliate of Target or any of its affiliates,
other than cash advances in the ordinary course of business. To the best
knowledge of Parent and Target, all of the Loans originated, sold or held as of
the date hereof and at the Effective Time by Target and its Subsidiaries, and
any other Loans purchased and held as of the date hereof and at the Effective
Time by Target and its Subsidiaries, were solicited, originated and exist, and
will exist at the Effective Time, in material compliance with all applicable
loan policies, loan sale agreements and procedures of Target and its
Subsidiaries; were solicited, originated and exist, and will exist at the
Effective Time, in material compliance with all applicable laws and contractual
provisions; are based upon valid, binding and enforceable agreements to which
Target has good title, free and clear of all Liens; and the collateral for each
of the Loans that is secured is (i) the borrower's rights in the collateral
described in the applicable security agreement, mortgage, pledge, collateral
assignment or other security document, and (ii) subject to a valid, enforceable
and perfected Lien; provided however that the enforceability of loan agreements
and Lien is subject to bankruptcy, reorganization, insolvency, and similar laws
of general application relating to or affecting the rights or remedies of
creditors generally, and to equitable principles that may be applied by a court
in construing or enforcing such agreements or Liens. All Loans serviced by
Target for third parties have been billed, collected and serviced in material
compliance with the terms of such Loans, any applicable servicing agreement, and
applicable law. Target has not made, is not making and shall not be deemed to
have made, any representation as to the collectibility of any Loan, the value of
any collateral, or the creditworthiness, credit history or financial condition
of any primary or secondary obligor under any Loan, or any guarantor or surety
thereof, in this Agreement or any agreement, instrument or other document
executed in connection with any of the transactions contemplated hereby or
provided or prepared pursuant hereto or in connection with any of the
transactions contemplated hereby.

   4.21 Loan Portfolio. Schedule 4.21 lists all of the loans in original
principal amount in 

                                      22

1998, are classified by Target 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 all such loans by
category, it being understood that no representation is being made that the
FDIC, the OTS or any other Bank Regulator would agree with the loan
classifications of Target.

   4.22 Accuracy of Deposit Schedules. The information to be delivered pursuant
to Section 2.10.1 shall accurately reflect Target's allocation of deposits among
the Target Offices and the Trust Business revenues and will be complete and
accurate, to the knowledge of Target, in all material respects as of the date
thereof, and the account records related to such deposits, to the knowledge of
Target, are and will be complete and accurate in all material respects as of the
date hereof. Notwithstanding the foregoing, Target makes no representation that
Target's allocation of deposits among the Target Offices in any way reflects the
current preferences or expectations of its customers as to the Target Office at
which they do any significant portion of their banking business.

   4.23 Accuracy and Availability of Deposit Account Records. The deposit
agreements and other documents relating to the Deposits to be delivered to
Purchaser will be all such documents in Target's possession or reasonably
available to Target at the Closing, and the account records related to such
deposits, to the knowledge of Target, are and will be complete and accurate in
all material respects as of the date hereof. Notwithstanding the foregoing,
Target makes no representation that Target's allocation of deposits among the
Target Offices in any way reflects the current preferences or expectations of
its customers as to the Target Office at which they do any significant portion
of their banking business.

   4.24 Properties. All real and personal property owned by Target or its
Subsidiaries or presently used by any of them in its respective business is or
as of the Closing will be in an adequate condition (ordinary wear and tear
excepted) and is (and as of the Closing will be) sufficient to carry on the
business of Target and its Subsidiaries in the ordinary course of business
consistent with their past practices. With respect to real property, Target and
its Subsidiaries will have title (or, in the case of leases, leasehold
interests) of the type described in Section 2.10.3, except as described in
Schedule 4.24. Target and its Subsidiaries have or will have at the Closing
title, free and clear of all Liens (other than equities of redemption under
applicable foreclosure laws), to all of the material personal properties and
assets reflected on the consolidated statement of financial condition of Target
as of December 31, 1998 included in the Target Financial Statements or acquired
after such date, except (i) Liens for current taxes not yet due or payable, (ii)
pledges to secure deposits and other Liens incurred in the ordinary course of
its banking business, (iii) such imperfections of title, easements and
encumbrances, if any, as are not material in character, amount or extent, (iv)
those items that secure public or statutory obligations or any discount with,
borrowing from, or obligations to any Federal Reserve Bank or Federal Home Loan
Bank, (v) as reflected on the consolidated statement of financial condition of
Target as of December 31, 1998 included in the Target Financial Statements, and
(vi) as disclosed in Schedule 4.24. All real and personal property which is
material to Target's business on a consolidated basis and leased or licensed by
Target or any Target Subsidiary is held pursuant to leases or licenses which to
Target's knowledge are valid and enforceable in accordance with their respective
terms. Neither Target nor any of the Target Subsidiaries has received any notice
from any Governmental Entity of any violation of any law, ordinance, regulation,

                                      23
<PAGE>
 
license, permit or authorization issued with respect to any of the real property
that has not been corrected heretofore, and no such violation now exists which
could reasonably be expected to have an adverse effect on the operation or value
of any of the real property. All improvements constituting a part of the
property are in compliance in all material respects with all applicable laws,
ordinances, regulations, licenses, permits and authorizations, and there are
presently in effect all licenses, permits and authorizations required by law,
ordinance, or regulation.

   4.25 Tenants; Leases. Schedule 4.25 hereto lists each landlord or lessor
under any leases whose consent is required for the transfer of the lease to
Purchaser or the subsequent transfer to the Bank Parties effected by the
Purchase Agreement. Schedule 4.25 hereto discloses whether such transfer
(assuming receipt of appropriate consents) will give any landlord or lessor
under any lease any right or remedy under any lease. Except for the tenants
disclosed in Schedule 4.25 hereto, there are no tenants or other occupants of
the real properties owned by Target or any Target Subsidiary. To Target's and
Parent's knowledge, except as disclosed in Schedule 4.25 hereto, each of the
leases is in full force and effect, and Target is not in default under any of
its obligations thereunder.

   4.26 Labor. Target and Target Subsidiaries employ approximately 136 full-time
employees and 26 part-time employees, and they generally enjoy good employer-
employee relationships. No work stoppage involving Target or any Target
Subsidiary is pending or, to the best knowledge of Target and Parent,
threatened. Neither Target nor any Target Subsidiary is involved in, or
threatened with or affected by, any labor dispute, arbitration, lawsuit or
administrative proceeding involving the employees of Target or any Target
Subsidiary which is reasonably expected to have a Material Adverse Effect on
Target. Employees of Target and the Target 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 Target's and Parent's
knowledge, there have been no efforts to unionize or organize any employees of
Target or any of the Target Subsidiaries during the past five years. Upon
termination of the employment of any of said employees, neither Purchaser nor a
Bank Party will by reason of the Acquisition, the transfer of the Bank Business
to the Bank Parties, or anything done prior to the Effective Time be liable to
any of said employees for so-called "severance pay" or any other payments,
except as set forth in Schedule 4.26. Target and Target Subsidiaries do not have
any policy, practice, plan or program of paying severance pay or any form of
severance compensation in connection with the termination of employment, except
as set forth in said Schedule 4.26, and each is in compliance in all material
respects with all applicable laws and regulations respecting labor, employment,
fair employment practices, work place safety and health, terms and conditions of
employment, and wages and hours.

   4.27 Material Interests of Certain Persons. Except as disclosed in Schedule
4.27, to the knowledge of Target, no officer or director of Target, 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 Target or any of the Target Subsidiaries or (ii)
is indebted to, or has the right under a line of credit to borrow from, Target
or any Target Subsidiary, in an amount exceeding $50,000.

   4.28 Trust Business; Administration of Fiduciary Accounts.

     (a)  Target (i) has been duly appointed to all fiduciary or representative
capacities it holds 

                                      24
<PAGE>
 
with respect to the Trusts and all such appointments are currently in effect,
(ii) has all other authorizations or approvals necessary to conduct its Trust
Business, (iii) has all other licenses or permits necessary for the conduct of
its Trust Business except as disclosed in Schedule 4.28, and (iv) has or will
have, as of the Closing Date, all licenses necessary for the conduct of the
Trust Business. Target and each Target Subsidiary has properly administered all
accounts for which it acts as a fiduciary, including but not limited to accounts
for which it serves as a trustee, agent, custodian, personal representative,
guardian, conservator or investment advisor, in accordance with the terms of the
governing documents and applicable state and federal law and regulation and
common law. Except as disclosed in Schedule 4.28, to Target's and Parent's
knowledge neither Target nor any of its Subsidiaries nor any of their respective
directors, officers or employees has committed any breach of trust with respect
to any such fiduciary account, and the accountings for each such fiduciary
account are true and correct and accurately reflect the assets of such fiduciary
account.

     (b)  Neither Target nor, to the knowledge of Parent and the Target, any
Person "associated" (as defined under the Investment Advisers Act of 1940, as
amended (the "Advisers Act")) with the Target, has been convicted of any crime
or is or has engaged in any conduct that would be a basis for denial, suspension
or revocation of registration of an investment adviser under Section 203(e) of
the Advisers Act or would need to be disclosed pursuant to Rule 206(4)-4(b)
thereunder, and to the knowledge of the Parent and the Target, there is no
proceeding or investigation that is reasonably likely to become the basis for
any such disqualification, denial, suspension or revocation.  Except as
disclosed in Schedule 4.28, the Target and each of its investment adviser
representatives (as such term is defined in Rule 203A-3(a) under the Advisers
Act) has, and after giving effect to the Closing, will have, all material
permits, registrations, licenses, franchises, certifications and other approvals
(collectively, the "Licenses") required from foreign, federal, state or local
authorities in order for it to conduct the businesses presently conducted by the
Target in the manner presently conducted by the Target.  The Target is not a
"broker" or "dealer" within the meaning of the Exchange Act, or a "commodity
pool operator" or "commodity trading adviser" within the meaning of the
Commodity Exchange Act.  None of  the Target or its officers and employees is
required to be registered as a broker or dealer, a commodity trading adviser, a
commodity pool operator, a futures commission merchant, an introducing broker, a
registered representative or associated Person, a counseling officer, an
insurance agent, a real estate broker, a sales person or in any similar capacity
with the Securities and Exchange Commission, the Commodity Futures Trading
Commission, the National Futures Association, the National Association of
Securities Dealers, Inc., or the applicable commission of any state or any self-
regulatory body.

   4.29 Books and Records. The books of account, minute books, stock record
books, and other records of the Target and the Target Subsidiaries, all of which
have been made available to Purchaser, are complete and correct and have been
maintained in accordance with sound business practices and including the
maintenance of an adequate system of internal controls. The minute books of the
Target and the Target Subsidiaries contain accurate and complete records of all
corporate action taken by the stockholders and the Boards of Directors, and no
meeting of any such stockholders, Board of Directors, or committee has been held
for which minutes have not been prepared and are not contained in such minute
books. At the Closing, all of those books and records will be in the possession
of the Target.

   4.30 Accounts Receivable and Payable. All accounts receivable of the Target
that are 

                                      25
<PAGE>
 
reflected on the Target Financial Statements (collectively, the "Accounts
Receivable") represent or will represen t valid obligations arising from sales
actually made or services actually performed in the ordinary course of business.
All accounts payable of Target as of the Closing Date shall be accrued or paid
by Target as of the Closing Date in the ordinary course of business consistent
with past practices.

   4.31 Account Allowances. Target has secured within five years of the date
hereof judicial allowance of its account as trustee, executor, administrator,
guardian or conservator of each Trust with assets having an aggregate fair
market value in excess of $750,000 as of the date hereof that is now or was
previously subject to continuing superior court supervision, with the exception
of those Trusts shown on Schedule 4.31 hereto to have had no judicial account
allowance within five years of the date hereof.

   4.32 Location and Conduct of Business. Except as disclosed in Schedule 4.32,
Target conducts all of the customer operations of the Bank Business and the
Trust Business at the Target Offices and at no other locations. Target has no
other place of business within the meaning of the Advisers Act.

   4.33 Year 2000 Compliance. Target and its Subsidiaries have undertaken a
comprehensive assessment of the steps necessary to address the software,
accounting and recordkeeping issues raised in order for the data processing
systems used in the businesses conducted by Target and its Subsidiaries to be
Year 2000 compliant on or before the end of 1999 and have developed, and are
implementing a plan to deal with Year 2000 compliance issues. Target does not
expect its future cost of addressing its internal Year 2000 compliance issues to
be in excess of $100,000. Neither Target nor any Target Subsidiary has received
a rating of less than satisfactory from any regulatory agency with respect to
Year 2000 compliance.

   4.34 Intellectual Property. Schedule 4.34 to this Agreement lists all of the
material intellectual property (including all material trade names, trademarks,
service marks, patents, patent rights, copyrights, trade secrets, proprietary
process, software and other industrial and intellectual property rights
(collectively, "Intellectual Property") that Target uses in the conduct of its
business as it is presently being conducted. Target has good and valid license
agreements giving it the right to use all material intellectual property
necessary to the conduct of Target's business as presently conducted. There is
no claim, suit, action or proceeding, pending or, to the knowledge of Parent or
Target after due inquiry by Target, threatened, against Target asserting that
Target's use of any Intellectual Property infringes the rights of any third
party or otherwise contesting its rights with respect to any Intellectual
Property, and no third party is known to Target to be infringing upon the rights
of Target in the Intellectual Property.

   4.35 No Further Representations. Neither Parent nor Target has made, and
neither shall be deemed to have made, to Purchaser or any Bank Party any
representation or warranty other than as expressly set forth in this Article IV.
Without limiting the generality of the foregoing, and notwithstanding any
otherwise express representations and warranties made in this Article IV,
neither Parent nor Target makes any representation or warranty to Purchaser with
respect to any projections, estimates or budgets heretofore delivered to or made
available to Purchaser of future revenues, expenses or expenditures or future
results of operations; or except as expressly covered by a representation and
warranty contained in this Article IV, any other information or documents
(financial or otherwise) made available to Purchaser or its counsel, accountants
or advisers.

                                   Article V

       Representations and Warranties of Purchaser and Purchaser Parent

   Purchaser and Purchaser Parent (and to the extent specifically provided,
each Bank Party) hereby represent and warrant to Parent and Target as follows:

   5.1 Organization, Standing and Authority of Purchaser. Purchaser is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Connecticut with full corporate power and authority to own or
lease all of its properties and assets and to carry on its business as now
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

accountants, with respect to Purchaser Parent. The Purchaser Parent Financial
Statements referred to herein, as well as the Purchaser Parent Financial
Statements to be delivered pursuant to Section 7.4 hereof, fairly present or
will fairly present, as 

                                      28
<PAGE>
 
the case may be, in all material respects the consolidated financial condition
of Purchaser Parent as of the respective dates set forth therein, and the
consolidated results of operations, shareholders' equity and cash flows of
Purchaser Parent for the respective periods or as of the respective dates set
forth therein, subject, in the case of unaudited statements, to the addition of
notes and to normal and recurring year-end adjustments.

     5.4.2. Each of the Purchaser Parent Financial Statements referred to in
Section 5.4.1 has been or will be, as the case may be, prepared in accordance
with generally accepted accounting principles consistently applied during the
periods involved, except as stated therein.

   5.5 Material Adverse Change. Since December 31, 1997 (i) each of Purchaser
and Purchaser Parent has conducted its business in the ordinary and usual course
(excluding the incurrence of expenses in connection with this Agreement, and
excluding the transactions contemplated hereby) and (ii) no event has occurred
or circumstance arisen that, individually or in the aggregate, has had or is
reasonably likely to prevent or hinder the transactions contemplated by this
Agreement.

   5.6 Purchaser Investigation. Each of Purchaser, Purchaser Parent and the Bank
Parties acknowledges that: (i) it has had the opportunity to visit with Target
and meet with its representative officers and other representatives to discuss

operations of Target, and (ii) all materials and information requested by
Purchaser or Purchaser Parent and the Bank Parties have been provided to
Purchaser or Purchaser Parent or the Bank Parties to the reasonable satisfaction
of such party. Each of Purchaser and Purchaser Parent and the Bank Parties
acknowledges that it has made its own independent examination, investigation,
analysis and evaluation of Target, including its own estimate of the value of
Target's or the appropriate Branch Subset's business. Each of Purchaser and
Purchaser Parent and the Bank Parties acknowledges that it has undertaken such
investigation (including a review of the assets, liabilities, books, records and
contracts of Target) as Purchaser, Purchaser Parent or the Bank Parties deems
adequate, including that described above. Purchaser hereby confirms that (i) it
is acquiring the Target Common Stock for its own account, and not for, with a
view to, or in connection with the resale or distribution thereof; and (ii) it

investigations or proceedings instituted, pending or, to the best knowledge of

Purchaser or Purchaser Parent, threatened, disputes or controversies between
Purchaser, Purchaser Parent or any Bank Party and any federal, state or local
Governmental Entity that (i) could reasonably be expected to prevent or impair
the ability of Purchaser or Purchaser Parent to perform its obligations under
this Agreement or any Bank Party to perform its obligations under the Purchase
Agreement in any material respect or (ii) could reasonably be expected to impair
the validity or consummation of this Agreement or the transactions contemplated
hereby (including the Acquisition and the subsequent transactions effected by
the Purchase Agreement). Purchaser Parent has sufficient sources of funds
available to it to be able to capitalize Purchaser in an 

                                      29
<PAGE>
 
amount sufficient to enable Pur chaser to pay the Purchase Price without being
required to seek funding from third parties, and Purchaser believes that it can
satisfy all capital and other regulatory requirements necessary to obtain all
Regulatory Approvals, and that it will be able to meet such requirements after
payment of the Closing Dividend.

Purchaser Parent, Purchaser nor any Purchaser Subsidiary, nor any of their
respective directors, officers or employees, has employed any broker or finder

Target, or except as expressly covered by a representation and warranty
contained in this Article V, any other information or documents (financial or
otherwise) made available to Parent or Target or its counsel, accountants or
advisers. For purposes of this Article V each Purchaser Representing Party shall
be deemed to be making representations only as to itself and its Affiliates, and
not as to any other, unrelated party.

servicing rights and/or collateralized mortgage obligations, and otherwise as
expressly contemplated by this Agreement); use commercially  reasonable efforts
to preserve intact its business organization and assets and maintain its rights
and franchises; and take no action which would (i) materially adversely affect
the ability of Purchaser, Target or the Bank Parties to obtain 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) 

                                      30
<PAGE>
 
materially adversely affect its ability to perform its covenants and agreements
under this Agreement. Without limiting the foregoing, during such period, Target
will perform in a prompt and timely manner, in accordance with its ordinary
course of business consistent with past practices or existing business plans,
all of its obligations with respect to the Bank Business as provided in Schedule

facilities before the Final Approval Date. Target agrees that it shall conduct
the Bank Business and Trust Business, as applicable, in accordance with sound
banking, fiduciary and commercial practices consistent with past practices or
existing operating policies and business plans and will use its commercially
reasonable best efforts to preserve for the benefit of Purchaser the goodwill

<PAGE>
 
     employment or severance agreements with Target; (iii) enter into any
     employment, severance or similar agreements or arrangements (provided that
     Target may employ an employee in the ordinary course of business if the
     employment of such employee is terminable by Target at will without
     liability, other than as required by law) with any director or employee
     (except that Target may provide at the expense of Purchaser for "stay for
     pay" arrangements with key employees in an amount not to exceed $200,000 in
     the aggregate and that Parent may provide reasonable additional "stay for
     pay" arrangements at its own expense after reasonable consultation with

confer with representatives of Purchaser and report the general status of its
ongoing operations at such times as Purchaser may reasonably request but no more

complaints, investigations or hearings (or communications indicating that the
same may be contemplated), or the institution of litigation or the threat of
material litigation involving Target. Target will also provide Purchaser such
information with respect to such events as Purchaser may reasonably request from

for such month prepared in accordance with past practices.

   6.4 All Reasonable Efforts. Subject to the terms and conditions herein
provided, Target and Parent agree 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
and the Related Documents.

   6.5 Failure to Fulfill Conditions. In the event that Target or Parent

Acquisition cannot be fulfilled and (in the event that the notifying party has
the right to waive such condition) that it will not waive that condition, it
will promptly notify Purchaser.

   6.6 Regulatory Approvals. Target shall use reasonable efforts to assist
Purchaser in obtaining all required Regulatory Approvals. Target shall provide
Purchaser or the appropriate regulatory authorities all information reasonably
required to be submitted by Target in connection with the Regulatory Approvals.

any party hereto to obtain any Regulatory Approval or to perform such party's
covenants and agreements under this Agreement.

   6.7 Corporate and Other Consents. Target and Parent shall use commercially
reasonable efforts (which shall not require Target or Parent to pay any money or
other consideration to any Person or to initiate any claim or proceeding against
any Person) to secure all corporate and other non-regulatory consents (except

Purchaser shall fully cooperate in order to obtain such consents. Target shall
provide copies of such consents to Purchaser upon Purchaser's request.

   6.8 Lease Consents and Obligations. Target and Parent shall use commercially

transfer of said leases by Purchaser to the Bank Parties under the Purchase
Agreement, and Purchaser shall fully cooperate in order to obtain such consents.
In 

                                      33
<PAGE>
 
addition, Target and Parent agree to use such commercially reasona ble efforts
to renew or extend those Leases identified on Schedule 6.8.

   6.9 Nonsolicitation of Purchaser's Employees. In consideration of the
consummation of the transactions contemplated hereby, Parent agrees that, for a
period of one year following the Closing Date, it shall not, directly solicit
for employment, retain as an independent contractor or consultant, induce to
terminate employment with Purchaser or otherwise interfere with Purchaser's
employment relationship with any former employee of Target who becomes an
employee of Purchaser ("Transferred Employee"); provided, however, that Parent
shall be permitted to retain any such Transferred Employee who has responded to
a general employment inquiry of the Parent not specifically targeted to such
Transferred Employee. It is expressly acknowledged by the parties hereto that
Parent may employ or retain as an independent contractor or consultant any such
Transferred Employee or other such employee of Purchaser who shall terminate his
or her employment with Purchaser, without any such direct or indirect inducement
or interference by, or other pre-termination contact with, Parent or who shall
be terminated by Purchaser, in either case after the Closing Date. For purposes
of this Section 6.9, the term "Purchaser" shall be deemed to include any
Affiliate of Purchaser or any of the Bank Parties.

   6.10 Access to and Retention of Books and Records. Upon execution of this
Agreement, Target shall provide Purchaser and the Bank Parties and their
representatives, accountants and counsel reasonable access to the Target
Offices, employees, depository records, Loan files, and all other documents and
other information concerning the Target Offices as a Bank Party may reasonably
request; provided that with respect to Target employees, Target's sole
obligation shall be to provide the requesting Bank Party with information
concerning the name, position, date of hire and salary of Target employees.
Target shall provide each Bank Party reasonable assistance in its investigation
relating to the Target Offices; provided that the Bank Party's investigation
shall be conducted in a manner which does not unreasonably interfere with
Target's normal operations, customers and employee relations and provided
further that if the Bank Party's investigation occurs during non-business hours,
the expenses incurred by Target as a result of such investigation during non-
business hours shall be paid by such Bank Party to Target promptly upon the
receipt of an invoice therefor. On the Closing Date, to the extent practicable,
Purchaser and Purchaser's designee shall receive possession of, and all right,
title and interest of Target in, all books and records relating to the Bank
Business and the Trust Business, the Assumed Liabilities, and the operation of
the Target Offices which are in the possession of Target.

   6.11 Data Processing and Transfer Services. Target agrees to provide to
Purchaser other data processing and transfer services as set forth in Schedule
6.2.1 hereof, provided, however, that without the permission of Parent no
information shall be sent to Target Customers and no changes shall be made at or
to Target's facilities before the Final Approval Date.

   6.12 Automated Clearing House Entries. Prior to the Closing Date, Target will
make reasonable efforts to notify all originators of Automated Clearing House
("ACH") entries affecting deposits or Loans of the terms and effect of the
Acquisition, to facilitate Purchaser's transfer of the accounts to the Bank
Parties immediately after the Closing.

   6.13 Communications; Notices; etc. Subject to regulatory restrictions:

     6.13.1. Target agrees that promptly following the execution of this
Agreement, Target and Purchaser shall conduct information meetings at the Target

                                      34
<PAGE>
 
location as Purchaser and Target shall mutually agree, to announce Purchaser's
proposed acquisition of Target to the employees. Target and Purchaser shall
mutually agree as to the scope and content of all initial communications to the
employees. Thereafter, Purchaser shall be permitted to meet with Target
employees, at times mutually convenient to Purchaser and Target to discuss
employment opportunities with Purchaser. From and after the date on which the
last regulatory approval required to permit consummation of the Acquisition has
been obtained ("Final Approval Date"), Purchaser shall be permitted to conduct
training sessions during normal business hours or at other times with Target
employees; provided that Purchaser will use reasonable efforts to schedule such
training sessions in a manner which does not interfere with Target's normal
business operations. Purchaser shall reimburse Target employees for
transportation costs to and from the location where Purchaser shall train such
employees and compensate Target employees at their respective applicable
standard or overtime rates for the time spent in such training.

     6.13.2. After the Final Approval Date and prior to the Closing Date, on a
date certain which is mutually agreeable to the parties, Target and Purchaser
shall each send statements (or, in the event the parties shall mutually agree,
the parties shall send a joint statement) to Target's customers announcing the
transactions contemplated hereby.  From time to time prior to the Closing,
Purchaser or a Bank Party may request consent to transmit certain communications
to Target Customers, and Target agrees that it will not unreasonably withhold
such consent.

     6.13.3. Purchaser and Target shall each furnish to the other copies of the
text of all notices (including with respect to IRA accounts), advertisements,
information or communications, written or oral, proposed to be sent or
transmitted by the furnishing party to employees, customers or the public
generally regarding the proposed or actual transfer of the Bank Business and/or
the purchase and sale of the Target Offices (including any public notices
required to be given by law or regulation in connection with such transactions
or applications for approval thereof), and the furnishing party shall not send
or transmit such notices, advertisements, information or communications or
otherwise make them public unless and until the prior consent of the other party
shall have been received (such consent not to be unreasonably withheld or
delayed); provided, however, that nothing in this Section 6.13 shall (i)
prohibit any party from making any press release or announcement which its legal
counsel reasonably deems necessary under law, if it makes a good faith effort to
obtain the other party's consent to the text of the press release or
announcement before making it public, or (ii) require Target to furnish to
Purchaser or obtain Purchaser's consent for any communication (A) made in an ad
hoc fashion that is responsive to issues or questions of any employees or
customers and does not disparage Purchaser, or (B) that makes factual statements
about the transactions contemplated hereby and does not disparage Purchaser.

   6.14 Regulatory Authorizations. Target shall, and Parent shall cause Target
and its employees to, use reasonable efforts to obtain all authorizations,
consents, orders, approvals and licenses of federal, state and local regulatory
bodies and officials that may be or become necessary for their respective
execution and delivery of, and the performance of their respective obligations
pursuant to, this Agreement and the other agreements, documents and instruments
contemplated hereby, and for Target to conduct the Trust Business.

event no

rights if Purchaser does not consent to the terms of such sale, which consent
shall not be unreasonably withheld or delayed. Parent agrees that it will
maintain accounts at Target or any successor thereto at Closing for a period of
two (2) years with balance levels over such period generally not less than those
maintained by Parent ("Parent Accounts") during the one year period prior to the
date hereof, provided that the level of service and the interest rates provided
to Parent are not substantially diminished from those prevailing during such one
year period, and provided that Parent shall continue to have legal authority to

20 officers of Target, at the level of Vice President or above, under the NLT
Severance Plan as described in Schedule 4.11(i). Parent shall be solely
responsible for bearing the cost of such extended payments, to the extent they
exceed the amounts otherwise payable under the NLT Severance Plan (and no NLT
Severance Plan benefits (whether the obligation of Parent, on the one hand, or
of Target, Purchaser or a Bank Party, on the other hand) shall be accrued or
expensed in calculating either the Estimated Balance Sheet or the Final Balance
Sheet).

          6.17.4. Parent shall cause Target to obtain the agreement of each

provided, Purchaser Parent, Purchaser and each Bank Party agree to use all

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.

      7.6 Failure to Fulfill Conditions . In the event that any of Purchaser
Parent, Purchaser or any Bank Party determines that a condition to any party's
obligation to complete the Acquisition cannot be fulfilled and that it will not
waive that condition, it will promptly notify Target.

      7.7 Employee Benefits

         7.7.1. All employees of Target as of the Effective Time shall either be
(i) offered a "Comparable Job" (as defined in the NLT Severance Plan as in
effect on the date of this Agreement) by Purchaser Parent or its Affiliate or a
Bank Party as of the Effective Time or (ii) entitled to benefits in accordance
with the NLT Severance Plan. Nothing in this Agreement shall give any employee
of Target or its Subsidiaries a right to continuing employment with Purchaser
Parent or any Affiliate thereof or a Bank Party after the Effective Time. Any
employee of Target whose employment with Purchaser Parent, an Affiliate thereof
or a Bank Party is terminated by Purchaser Parent, an Affiliate thereof or a
Bank Party within one year after the Effective Time for other than cause shall
be entitled to benefits in accordance with the NLT Severance Plan (which
benefits shall be post-Effective Time obligations of Target, Purchaser or a Bank
Party and in no event shall be accrued or expensed in calculating either the
Estimated Balance Sheet or the Final Balance Sheet).

         7.7.2. As soon as practicable after the Effective Time, Purchaser
Parent (or an Affiliate) and the Bank Parties shall provide or cause to be
provided to all employees of Target who are offered employment by Purchaser
Parent, an Affiliate thereof or a Bank Party after the Effective Time with
employee benefits which, in the aggregate, are no less favorable than those
generally afforded to other similarly situated employees of Charter Trust
Company (in the case of employees offered employment by Purchaser Parent or an
Affiliate thereof) or of the relevant Bank Party (in the case of employees
offered employment by a Bank Party) 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 Target or any Target Subsidiary prior to
the Effective Time shall be treated as service with an "employer" as if such
Persons had been employees of Purchaser Parent, an Affiliate thereof or the Bank
Party, (ii) this Section 7.7 shall not be construed to limit the ability of
Purchaser Parent and its Affiliates or any Bank Party to terminate the
employment of any employee or to review employee benefits programs from time to
time and to make such changes or terminate such plans as they deem appropriate,
and (iii) neither Purchaser Parent nor any of its Affiliates nor any Bank Party
shall be required to provide any employees or former employees of Target with
post-retirement medical benefits more favorable than those provided to new hires
of Charter Trust Company or of the relevant Bank Party, as the case may be.
Subject to Section 7.7.3 below, nothing in this Agreement shall be construed to
(i) obligate Purchaser Parent or any of its Affiliates to continue in effect for
any specific period of time after the Closing Date any of the Benefit Agreements
or (ii) restrict Purchaser Parent or any of its Affiliates from amending,
modifying or terminating any of the Benefit Agreements.



                                      39
<PAGE>
 
         7.7.3. Target has disclosed to Purchaser the agreements (collectively,
"Benefit Agreements") listed in Schedule 7.7.3. Following the Effective Time,
Purchaser Parent shall honor or cause its Subsidiaries to honor in accordance
with their terms all such Benefit Agreements and assume or cause its
Subsidiaries to assume all duties, liabilities and obligations under such
agreements and arrangements. Purchaser Parent agrees that the consummation of
the transactions contemplated hereby constitutes a "Change in Control" as
defined in the Benefit Agreements. All payments under the Benefit Agreements
that result from the transactions contemplated hereby shall be post-Effective
Time obligations of Target or Purchaser and in no event shall any such payments
be accrued or expensed in calculating either the Estimated Balance Sheet or the
Final Balance Sheet.

      7.8 Directors and Officers Indemnification and Insurance

         7.8.1. Purchaser shall cause Target to honor its indemnification
obligations with respect to each current director and officer of Target who is
not an employee, officer, or director of Parent and who serves as a director of
Target after the Effective Time ("Outside Directors") under applicable law and
regulation and the provisions of its By-laws, which provisions shall not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time in any manner that would affect adversely the rights thereunder
of such Outside Directors, unless such modification shall be required by law.
The provisions of this Section 7.8 are specifically for the benefit of the
Outside Directors.

         7.8.2. In the event that either Purchaser 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 Purchaser shall assume the obligations set forth in
this Section 7.8.

         7.8.3. Parent shall not assert any claim relating to any pre-Closing
act or omission against any Outside Director for which such Outside Director
would be entitled to indemnification under this Section 7.8.

         7.8.4. Neither Purchaser, any Purchaser Affiliate, nor any Bank Party
shall assert or permit Target to assert any claim relating to any pre-Closing
act or omission against any current or former officer or director of Target for
which Parent or Target might be required to provide indemnification.

      7.9 Non-Solicitation of Parent Employees. Purchaser agrees that, for a
period of one year following the Closing Date, it shall not, directly solicit
for employment, retain as an independent contractor or consultant, induce to
terminate employment with Parent or otherwise interfere with Parent's employment
relationship with any of Parent's employees whom Purchaser has identified in the
course of the Acquisition ("Parent Employee"); provided, however, that Purchaser
shall be permitted to hire any such Parent Employee who has responded to a
general employment inquiry of Purchaser not specifically targeted to such Parent
Employee. It is expressly acknowledged by the parties hereto that Purchaser may
employ or retain as an independent contractor or consultant any such Parent
Employee or other such employee of Parent who shall terminate his or her
employment with Parent, without any such direct or indirect inducement or
interference by, or other pre-termination contact with, Purchaser or who shall
be terminated by Parent, in either case after the Closing Date. For purposes of
this Section 7.9, the 


                                      40
<PAGE>
 
term "Purchaser" shall be deemed to include any Affiliate of Purchaser or any of
the Bank Parties.

connection with the IRS's determination letter or audit process or the IRS's
Voluntary Compliance Resolution Program, Closing Agreement Programs or similar
program) arising out of any matter disclosed in Schedule 4.16.4 or 4.16.7
(paragraph 2), provided that Target and Purchaser act reasonably and in good
faith with respect to such matters.

         8.1.5. Indemnified Liabilities . All such Damages described in the
foregoing subsections of this Section 8.1 are collectively referred to as
"Indemnified Liabilities."

     8.2 Environmental Matters . With respect to any Damages arising out of a
breach of the representation set forth in Section 4.12 hereof:

         8.2.1. Purchaser Indemnified Party shall, and shall cause any
applicable Subsidiary to, cooperate with any reasonable request by Parent to
enable Parent to perform its obligations under this Article VIII with respect to
such Indemnified Liabilities;

         8.2.2. Purchaser Indemnified Party shall promptly notify Parent of the
existence of any Indemnified Liabilities (with reasonable information as to
proposed plans for remediation, if appropriate, to be provided whenever the same
become available), but failure to so notify Parent promptly shall not relieve
Parent of any of its obligations hereunder in the absence of actual prejudice
and then only to the extent such actual prejudice is caused by such failure to
so notify Parent; and

         8.2.3. Notwithstanding any other provision of this Agreement to the
contrary, Damages relating to any environmental investigation, monitoring or
remediation (collectively, "Remedial Actions") that would otherwise constitute
Indemnified Liabilities shall be subject to indemnification only to the extent
that:  (i) the Remedial Action is required pursuant to Environmental Laws and
(ii) the Remedial Action is performed in a cost-effective manner, reasonable
under the totality of the circumstances, given due consideration for actual
current use of the property that is the subject of the Remedial Action.

     8.3 Indemnification Procedure . If a claim or demand by a third party is
made against an indemnified party, and if such party intends to seek indemnity
with respect thereto pursuant to this Article VIII or under any other provisions
of this Agreement providing for indemnification, such indemnified party shall
promptly notify the indemnifying party in writing of such claims or demands
setting forth such claims in reasonable detail. The failure of the indemnified
party to give the indemnifying party prompt notice as provided herein shall not
relieve the indemnifying 


                                      42
<PAGE>
 
party of any of its obligations under this Article VIII, except to the extent
that the indemnifying party is materially prejudiced by such failure. The
indemnifying party shall have 30 days after receipt of such notice to undertake,
conduct and control, through counsel of its own choosing and at its own expense,
the settlement or defense thereof, and the indemnified party shall cooperate
with it in connection therewith; provided, that the indemnified party may
participate in such settlement or defense through counsel chosen by such
indemnified party if the fees and expenses of such counsel shall be borne by
such indemnified party. So long as the indemnifying party is reasonably
contesting any such claim in good faith, the indemnified party shall not pay,
defend, or settle any such claim. Notwithstanding the foregoing, the indemnified
party shall have the right to pay or settle any such claim; provided, that in
such event it shall waive any right to indemnity therefor by the indemnifying
party. If the indemnifying party does not notify the indemnified party within 30
days after the receipt of the indemnified party's notice of a claim of indemnity
hereunder that it elects to undertake the defense thereof, the indemnified party
shall have the right to contest, settle or compromise the claim but shall not
thereby waive any right to indemnity therefor pursuant to this Agreement. The
indemnifying party shall not, except with the consent of the indemnified party,
enter into any settlement that does not include as an unconditional term thereof
the giving by the Person or Persons asserting such claim to all indemnified
parties (i.e., Parent Indemnified Parties or Purchaser Indemnified Parties, as
the case may be) an unconditional release from all liability with respect to
such claim or consent to entry of any judgment. Any Person entitled to
indemnification pursuant to this Article VIII shall be required to cooperate in
the defense and investigation of any claim as to which indemnification may be
sought and to cooperate with other indemnified parties so as to minimize the
costs of defending multiple indemnified parties. No indemnifying party shall be
obligated pursuant to this Article VIII to pay for more than one firm of counsel
for all indemnified parties.

    8.4 Limitation on Indemnification

         8.4.1. Parent Indemnification Threshold . Parent shall be required to
indemnify and hold harmless Purchaser Indemnified Parties with respect to
Damages incurred by such indemnified party only to the extent that the aggregate
amount of all such Damages of Purchaser Indemnified Parties exceeds $200,000
(the "Parent Threshold"), provided, however that the Parent Threshold shall be
zero for indemnity provided under Sections 8.1.3 (c) and 8.1.4.

         8.4.2. Purchaser Indemnification Threshold . Purchaser shall be
required to indemnify and hold harmless Parent Indemnified Parties with respect
to Damages incurred by such indemnified party only to the extent that the
aggregate amount of all such Damages of Parent Indemnified Parties exceeds
$200,000 (the "Purchaser Threshold"), provided, however that the Purchaser
Threshold shall be zero for indemnity provided under Section 8.1.1(d).

     8.5 Special, Consequential, and Punitive Damages not Indemnifiable. In no
event shall Parent, Purchaser, Purchaser Parent, or any Bank Party, as the case
may be, be liable to Purchaser Indemnified Parties or Parent Indemnified
Parties, respectively, for special, indirect, incidental, consequential or
punitive damages other than those recovered or recoverable by a third party from
a party seeking indemnification under this Article VIII .

    8.6 Indemnity Payments Reduced by Insurance Proceeds. Any indemnity payment
payable pursuant to this Agreement shall be decreased to the extent of any
insurance proceeds actually received by the indemnified party.

    8.7 Maximum Aggregate Liability. In no event shall the aggregate liability
of any 




                                      43
<PAGE>
 
party under Article VIII exceed $20 million, provided, however, that the
maximum aggregate liability of Parent under Article VIII shall be equal to the
sum of the Purchase Price and the Closing Dividend ("Larger Cap") in the event

                                  Article IX

                         Regulatory and Other Matters

 

     9.1 Regulatory Approvals

         9.1.1. As soon as practicable after the date hereof, each of Target,
Purchaser and the Bank Parties shall take all reasonable efforts to prepare all
necessary documentation, to effect all


                                      44
<PAGE>
 
necessary filings and to obtain all necessary permits, consents, approvals and
authorizations of all third parties and Governmental Entities necessary to
consummate the transactions contemplated by this Agreement, including without
limitation the Acquisition. Target, Purchaser, Purchaser Parent and the Bank
Parties will each cooperate with the other and will each furnish the other and
the 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 any application, petition or any
other statement or application made by or on behalf of Target, Purchaser,
Purchaser Parent or a Bank Party to any Governmental Entity in connection with
the Acquisition and the other transactions contemplated by this Agreement.
Target, Purchaser, Purchaser Parent and the Bank Parties shall have the right to
review in advance all filings and approve in advance all characterizations of
the information relating to them and any of their respective subsidiaries which
appear in any filing made in connection with the transactions contemplated by
this Agreement with any Governmental Entity. In addition, Target, Purchaser,
Purchaser Parent and the Bank Parties shall each furnish to the other a final
copy of each such filing made in connection with the transactions contemplated
by this Agreement with any Governmental Entity.

         9.1.2. Without limiting the generality of the foregoing, Purchaser,
Purchaser Parent and Purchaser Parent's parent and the Bank Parties will file
all regulatory applications necessary for the consummation of the transactions
contemplated hereby and by the Purchase Agreement within 45 days of the date of
this Agreement, and will respond to any OTS or other Bank Regulator comments on
such application within 15 days following the receipt thereof.  If any Bank
Party becomes unwilling or unable to consummate the transactions contemplated by
the Purchase Agreement in a timely manner and no other Bank Party has assumed
such obligation within 30 days, Purchaser, Purchaser Parent and Purchaser
Parent's parent will promptly amend its OTS application to seek approval to
accept deposits and to operate the Target Office(s) that such Bank Party
otherwise would have purchased, and the Bank Parties will each make any required
changes in their regulatory applications to conform such applications to the
revised structure of the Acquisition and divestiture of the Bank Business, and
all such parties will prosecute all such revised applications diligently in
order to minimize any delay caused by such amendments.

      9.2 Access and Investigation. Each of Target and Purchaser and the Bank
Parties shall permit the other party and its representatives reasonable access
to its properties and personnel, and shall disclose and make available to such
other parties all books, papers and records relating to the assets, stock
ownership, properties, operations, obligations and liabilities of it and its
Subsidiaries, including, but not limited to, all books of account (including the
general ledger), tax records, minute books of meetings of boards of directors
(and any committees thereof) and shareholders, organizational documents, bylaws,
material contracts and agreements, filings with any regulatory authority,
accountants' work papers, litigation files, loan files, plans affecting
employees, and any other business activities or prospects in which the other
party may have a reasonable interest, provided that such access shall be
reasonably related to the transactions contemplated hereby and, in the
reasonable opinion of the respective parties providing such access, not unduly
interfere with normal operations or violate applicable law. Each of Target,
Purchaser, the Bank Parties and their respective Subsidiaries shall make their
respective directors, officers, employees and agents and authorized
representatives (including counsel and independent public accountants) available
to confer with the other party and its representatives, provided that such
access shall be reasonably related to the transactions contemplated hereby and

                                      45
<PAGE>
 
shall not unduly interfere with normal operations.

      9.3 Confidentiality. All information furnished previously in connection
with the transactions contemplated by this Agreement or pursuant hereto shall be
treated as the sole property of the party furnishing the information until
consummation of the transactions contemplated hereby. Each party shall use its
best efforts to keep confidential all such information, and shall not directly
or indirectly use such information for any competitive or other commercial
purposes and, if such transactions shall not occur, the party receiving the
information shall either destroy or return to the party which furnished such
information all documents or other materials containing, reflecting or referring
to such information. The obligation to keep such information confidential shall
continue for five years from the date the proposed transactions are abandoned
but shall not apply to (i) any information which (x) the party receiving the
information can establish by convincing evidence was already in its possession
prior to the disclosure thereof by the party furnishing the information; (y) was
then generally known to the public; or (z) became known to the public through no
fault of the party receiving the information; or (ii) disclosures pursuant to a
legal requirement or in accordance with an order of a court of competent
jurisdiction, provided that the party which is the subject of any such legal
requirement or order shall use its best efforts to give the other party at least
ten business days prior notice thereof.

      9.4 Post-Closing Tax Matters


        9.4.1. Parent shall prepare or cause to be prepared and file or cause to
be filed all Tax Returns for Target and the Tax Subsidiaries with respect to all
periods beginning before the Closing Date that are filed after the Closing Date
and that are consolidated, unitary or combined Tax Returns that will include the
operations of Parent, Target and the Tax Subsidiaries, and will pay (or duly
contest the obligation to pay) all Taxes due in connection with such Tax
Returns. Target and the Tax Subsidiaries will furnish Tax information to Parent
for inclusion in such Tax Returns in accordance with their past custom and
practice. Parent will allow the Purchaser an opportunity to review and comment
upon such Tax Returns (including any amended returns) to the extent they relate
to the Target and its Tax Subsidiaries.

        9.4.2. Purchaser shall prepare or cause to be prepared and file or cause
to be filed any Tax Returns of Target and the Tax Subsidiaries, other than those
Tax Returns described in Section 9.4.1. Purchaser shall permit Parent to review
and comment upon each such Tax Return (including any amended return) described
in the preceding sentence that relates to taxable periods that begin before the
Closing Date, prior to filing to the extent that such Tax Return relates to any
of Target or a Tax Subsidiary. Parent shall pay to Purchaser within fifteen (15)
days after the date on which Taxes are paid with respect to such periods an
amount equal to the portion of such Taxes which relates to the portion of such
Taxable period ending on the Closing Date. For purposes of this Section 9.4, in
the case of any Taxes that are imposed on a periodic basis and are payable for a
Taxable period that includes (but does not end on) the Closing Date, the portion
of such Tax which relates to the portion of such Taxable period ending on the
Closing Date shall (x) in the case of any Taxes other than Taxes based upon or
related to income or receipts, be deemed to be the amount of such Tax for the
entire Taxable period multiplied by a fraction the numerator of which is the
number of days in the Taxable period ending on the Closing Date and the
denominator of which is the number of days in the entire Taxable period, and (y)
in the case of any Tax based upon or related to income or receipts be deemed
equal to the amount which would be payable if the relevant Taxable period ended
on the Closing Date. All determinations necessary to give effect to the
foregoing allocations shall be made in a manner consistent with 


                                      46
<PAGE>
 
the prior practice of Target.

         9.4.3. Purchaser, Target and Parent shall cooperate fully, as and to
the extent reasonably requested by the other party, in connection with the
filing of Tax Returns of Target and the Tax Subsidiaries pursuant to this
Section 9.4 and any audit, litigation or other proceeding with respect to Taxes
of Target and the Tax Subsidiaries. Such cooperation shall include the retention
and (upon the other party's request) the provision of records and information
that are reasonably relevant to any such audit, litigation or other proceeding
and making employees available on a mutually convenient basis to provide
additional information and explanation of any material provided hereunder.
Target and Parent agree (A) to retain all books and records with respect to Tax
matters pertinent to Target relating to any taxable period beginning before the
Closing Date until the expiration of the statute of limitations (and, to the
extent notified by Purchaser or Parent, any extensions thereof) of the
respective taxable periods, and to abide by all record retention agreements
entered into with any taxing authority, and (B) to give the other party
reasonable written notice prior to transferring, destroying or discarding any
such books and records and, if the other party so requests, Target or Parent, as
the case may be, shall allow the other party to take possession of such books
and records.

         9.4.4. Purchaser and Parent shall, upon request, use their best efforts
to obtain any certificate or other document from any Governmental Entity or any
other Person as may be necessary to mitigate, reduce or eliminate any Tax that
could be imposed (including, but not limited to, with respect to the
transactions contemplated hereby).

         9.4.5. Purchaser and Parent shall, upon request, provide the other
party with all information that either party may be required to report pursuant
to Code Section 6043 and all Treasury Department regulations promulgated
thereunder.

         9.4.6. Any tax sharing agreement between Parent and any of Target and
the Tax Subsidiaries shall be terminated as of the Closing Date and will have no
further effect for any taxable year (whether the current year, a future year, or
a past year).

         9.4.7. All transfer, documentary, sales, use, stamp, registration and
other such Taxes and fees (including any penalties and interest) incurred on
account of the sale of Target Stock Outstanding in connection with this
Agreement, shall be shared equally between Purchaser and Parent when due, and
Purchaser and Parent will, at their own expense, file all necessary Tax Returns
and other documentation with respect to all such transfer, documentary, sales,
use, stamp, registration and other Taxes and fees, and, if required by
applicable law, Parent will and Purchaser will, and each will cause its
Affiliates to, join in the execution of any such Tax Returns and other
documentation.

         9.4.8. Parent agrees to indemnify (in accordance with the procedures
and subject to the limitations set forth in Article VIII) Purchaser from and
against any and all Damages arising out of any Tax liability of any of Target
and the Tax Subsidiaries for Taxes of any Person other than any of Target and
the Tax Subsidiaries (A) under Treasury Regulation Section 1.1502-6 (or any
similar provision of state, local or foreign law), (B) as a transferee or
successor, (C) by contract, or (D) otherwise.

         9.4.9. Upon Purchaser's request on or prior to the Closing, Parent
will join with Purchaser in making an election under Section 338(h)(10) of the
Code (and any corresponding elections under state, local, or foreign tax law)
(collectively, a "Section 338(h)(10) Election") 

                                      47
<PAGE>
 
with respect to the purchase and sale of Target Stock Outstanding hereunder
(including, at Purchaser's option, a Section 338(h)(10) Election with respect to
the deemed purchase and sale of the stock of a Tax Subsidiary). Parent will pay
any Tax attributable to the making of the Section 338(h)(10) Election. Parent
will also pay any state, local or foreign Tax. In the event that a Section
338(h)(10) Election is made, the parties agree that the Purchase Price and the
liabilities of Target and the Tax Subsidiaries (plus other relevant items) will
be allocated to the assets of Target and the Tax Subsidiaries for all purposes
(including Tax and financial accounting purposes) as shown on the Allocation to
be prepared pursuant to Section 9.4.10. Purchaser, Target, the Tax Subsidiaries,
and Parent will file all Tax Returns (including amended returns and claims for
refund) and information reports in a manner consistent with such allocation.

         9.4.10. Not less than 45 days before the due date for the filing of the
Section 338(h)(10) Election, Purchaser shall deliver to Parent a proposed
allocation (the "Allocation") of the Purchaser Price and the liabilities of
Target and the Tax Subsidiaries (plus any other relevant items) to the assets of
Target and the Tax Subsidiaries, prepared in accordance with the provisions of
Treasury Regulation Section 1.338(h)(10)-1(f).  Parent shall have the right to
review, comment on, and approve such allocation, provided, however, that such
approval shall not be unreasonably withheld.  Purchaser and Parent agree that
the Allocation shall apply for all purposes (including Tax and financial
accounting purposes), and that Purchaser, Target, the Tax Subsidiaries and
Parent will file all Tax Returns (including amended returns and claims for
refund) and information reports in a manner consistent with such Allocation.

         9.4.11. Purchaser agrees to indemnify (in accordance with the
procedures and subject to the limitations set forth in Article VIII) Parent for
any additional tax owed by Parent (including tax owed by Parent due to this
indemnification payment) resulting from any transaction not in the ordinary
course of business occurring on the Closing Date after Purchaser's purchase of
Target Stock Outstanding.

         9.4.12. Parent and Purchaser agree to report all transactions not in
the ordinary course of business occurring on the Closing Date after Purchaser's
purchase of Target Stock Outstanding on Purchaser's federal Income Tax Return to
the extent permitted by Treasury Regulation Section 1.1502-76(b)(1)(B).


         9.4.13. Any Tax refunds that are received by Purchaser or Target and
the Tax Subsidiaries, and any amounts credited against Tax to which Purchaser or
Target and the Tax Subsidiaries become entitled, that relate to Tax periods or
portions thereof ending on or before the Closing Date and not previously
included in the calculation of the total equity of Target reflected on the
Estimated Balance Sheet or Final Balance Sheet as an asset on the Estimated
Balance Sheet or Final Balance Sheet shall be for the account of Parent, and
Purchaser shall pay over to Parent any such refund or the amount of any such
credit within fifteen (15) days after receipt of such refund or entitlement to
such credit.

Parent shall not, directly or indirectly, conduct a personal trust service
business within the State or States of New Hampshire, Connecticut or Vermont.

     9.6 Further Assurances. On and after the Closing Date, Parent, Purchaser
and the Bank Parties will (i) provide such further assurances to each other,

applicable to Parent or any of its subsidiaries and, in any event, to notify
Parent before the destruction of any of such materials and, upon Parent's
request, to turn over to Parent any of such materials the proposed destruction
of which was notified to Parent.

      9.8 Access to Books and Records. Parent shall have the right for a period
of seven years following the Closing Date to have reasonable access to such
books, records and accounts, including financial and tax information,
correspondence, production records, employment records and other similar
information as are transferred to Purchaser pursuant to the terms of this
Agreement for the limited purposes of concluding its involvement in the business
of Target prior to the Closing Date, complying with its obligations under
applicable securities, tax, environmental, employment or other laws and
regulations, and defending against claims or litigation.

      9.9 No Solicitation.  From the date hereof until the termination of this
Agreement or the Closing Date, whichever occurs first, neither Parent nor any of

equity interest in, Target or any of its subsidiaries or any business
combination with Target or any of its subsidiaries or participate in any
negotiations regarding, or furnish to any other Person any information with
respect to, or otherwise cooperate in any way with, or assist or participate in,
facilitate, any effort or attempt by any other Person to do or seek any of the
foregoing, nor shall Parent nor any of its Subsidiaries enter into an agreement
with any Person not a party to this Agreement with respect to any such
transaction.  Parent shall notify Purchaser promptly if any such proposal or
offer, or any inquiry or contact with any Person with respect thereto, is made
and shall, in any such notice to Purchaser, indicate in reasonable detail the
terms and conditions of such proposal, offer, inquiry or contact.  Parent agrees
not to release any third party from, or waive any provision of, any

<PAGE>
 
         12.1.2. By either Parent or Purchaser (provided that the terminating
party is not then in material breach of any representation, warranty, covenant
or other agreement contained herein), if there has been a material breach on the
part of the other party of any representation, warranty or agreement contained

or such later date as shall have been agreed to in writing by Purchaser and
Parent; provided, that no party may terminate this Agreement pursuant to this
Section 12.1.3 if the failure of the Closing to have occurred on or before said

Agreement, and provided, further, that the Termination Date may be extended for
an additional two-month period by either party by written notice to the other
party (given not later than one week prior to the Termination Date) if the
Closing shall not have occurred because of failure to have obtained approval
from one or more Governmental Entities whose approval is required in connection
with this Agreement and the transactions contemplated hereby under circumstances
in which neither party has the right to terminate this Agreement pursuant to
Section 12.1.4 hereof; and provided, further, that the Termination Date may be
extended for an additional six-month period by Parent by written notice to
Purchaser (given not later than one week prior to the Termination Date) if the

contemplated by Section 9.1.2.

         12.1.4. By either Parent or Purchaser if final action has been taken

become unappealable and (ii) does not approve this Agreement or the transactions
contemplated hereby.


      12.2 Effect of Termination. In the event of termination of this

Agreement and remain in full force and effect, and Purchaser, Purchaser Parent
and the Bank Parties each agree not to solicit deposit accounts or trust
accounts of Target. Notwithstanding the foregoing sentence, Purchaser, Purchaser
Parent, the Bank Parties, and their respective Affiliates shall be permitted to
(a) engage in advertising, solicitations or marketing campaigns not primarily

     to Section 12.1.2 as a result of a wilful 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 


                                      53
<PAGE>
 
     12.1.2 hereof as a result of a breach of a representation, warranty
     or covenant which is caused by the wilful conduct or gross negligence of
     Parent or Target, such party shall be obligated to reimburse the other
     parties for up to $500,000 of out-of-pocket costs and expenses, including,
     without limitation, reasonable legal, accounting and investment banking
     fees and expenses, incurred by such other parties in connection with the
     entering into of this Agreement and the carrying out of any and all acts
     contemplated hereunder (collectively referred to as "Expenses").

                (c) In the event of a termination of this Agreement pursuant to
     Section 12.1.2 hereof as a result of a breach of a representation, warranty
     or covenant which is caused by the wilful conduct or gross negligence of
     Purchaser, Purchaser Parent, or a Bank Party, such breaching party shall be
     obligated to reimburse (1) first, Parent in full for all Expenses, and (2)

     such non-breaching party) in full for all Expenses.

                (d) No party shall be obligated to pay, and no party shall be
     entitled to receive, more than an aggregate of $500,000 as reimbursement of
     Expenses pursuant to this Section 12.2.1.

                 (e) Any payments required by this Section 12.2.1 will be
     payable within five business days after demand therefor by wire transfer of
     immediately available funds to an account designated by the party entitled
     to such payment.


          12.2.2. Except as provided in Section 12.2.1, whether or not the
Acquisition is consummated, all Expenses incurred in connection with this
Agreement and the transactions contemplated hereby shall be borne by the party
incurring such costs and expenses.

          12.2.3. The payment of Expenses is not an exclusive remedy, but is in
addition to any other rights or remedies available to the parties hereto at law
or in equity, including but not limited to specific performance to remedy any
violation of Section 9.9, and notwithstanding anything to the contrary contained
herein, no party shall be relieved or released from any liabilities or damages
arising out of its wilful breach or gross negligence.

      12.3 Amendment, Extension and Waiver . Subject to applicable law, at any
time prior to the Effective Time, Parent and Purchaser, by mutual agreement, may
(a) amend this Agreement, (b) extend the time for the performance of any of the
obligations or other acts 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) waive compliance with any of the agreements or
conditions contained herein. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of Parent and Purchaser. 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. Notwithstanding
the foregoing, no amendment, modification or waiver of or under this Agreement
shall be effective to increase materially the obligations of any Bank Party
hereunder without the consent of such Bank Party.

enforceable provision which, insofar as practical, implements the purposes and

Exhibit to this Agreement unless otherwise indicated. The recitals hereto

               (vii)  all obligations due under any service, maintenance or
     other contract relating to the Bank Business in effect at the Closing,
     regardless of whether such contract is assignable and/or included in
     Section 2.1(a)(v) or (viii), including costs of terminating any such
     contracts that Purchaser chooses to terminate in connection with the
     transactions contemplated by this Agreement; and

               (viii) any and all borrowings from the Federal Home Loan Bank of
     Boston or any other person related to the Bank Business ("Borrowings").

          (b) Purchaser shall not assume or be bound by any duties,
     responsibilities, obligations or liabilities of Target of any kind or
     nature, known, unknown, contingent or otherwise relating to the Trust
     Business as set forth in Schedule 2.2(b).  It is understood and agreed that
                              ---------------                                   
     Target is retaining the Capital Account and all of the liabilities relating
     to the Trust Business, except as otherwise expressly agreed to herein, and
     that Purchaser is assuming all liabilities relating to the Bank Business.

          (c) In the event that the Allocation Agreement fails to provide
     instructions with respect to a liability that Seller deems to be a Bank
     Liability,

                                       9
<PAGE>
 
     Seller shall transfer such liability to CB, LSB or MSB, as appropriate in
     accordance with Section 2.4, and such bank party shall assume such
     liability for consideration which is deemed to be equal to the
     consideration paid to Seller, if any, for assuming such liability pursuant
     to the Stock Purchase Agreement. In the event that the bank party objects
     to such transfer not later than 30 days after transfer, the matter shall be
     referred to arbitration pursuant to Section 14.16.

     Section 2.3.  Actions With Respect to IRAs.
                   ---------------------------- 

          (a) Seller shall cause Target to resign as of the close of business on
     the Closing Date as the custodian of each IRA of which it is the custodian.
     Seller shall also cause Target, to the extent permitted by the
     documentation governing each such IRA and applicable law, to (i) appoint
     CB, LSB or MSB, as instructed by Purchaser in accordance with the
     Allocation Agreement, as successor custodian of each such IRA, and
     Purchaser agrees to accept each such custodianship under the terms and
     conditions of Target's documents for its IRAs, and assume all fiduciary and
     custodial obligations with respect thereto as of the close of business on
     the Closing Date, and (ii) deliver to the IRA owner of each such IRA  such
     notice of the foregoing as is required by the documentation governing each
     such IRA or applicable law.  The parties agree that such resignation and
     appointment shall be effected by instrument substantially in the form of
     the IRA Resignation and Custodian Appointment attached as Schedule 5.3(h).
                                                               -------- ------  
     Each of CB, LSB and MSB, as applicable, shall be responsible for delivering
     its IRA documents to the applicable IRA owner, including but not limited to
     a beneficiary designation form to be completed by the applicable IRA owner;
     provided, however, that in the event that an IRA owner dies before such
     time Purchaser receives a properly completed beneficiary designation form,
     Target shall make available to Purchaser such information as may exist in
     Target's files regarding any beneficiary designation it may have regarding
     such decedent.  If, pursuant to the terms of the documentation governing
     any such IRA or applicable law, the owner designates a successor custodian
     other than CB, LSB or MSB, as applicable, all such IRAs shall be excluded
     from the Deposit Liabilities (such excluded Deposits Liabilities being
     herein called the "Excluded IRAs") and the Excluded IRAs shall be
     transferred to the designated custodian by Seller.

          (b) The Deposit Liabilities may include certain IRAs the owners of
     which are receiving periodic distributions either at the owner's request or
     because the owner has attained the age of 70 1/2.  In such event each of
     CB, LSB or MSB agrees to continue to make such periodic distributions in
     accordance with the distribution instructions received from Target.

     Section 2.4.  Adjustments in Assets and Liabilities.  While it is the
                   -------------------------------------                  
intent of the parties to divide the Bank Business and Trust Business between the
Purchaser and

                                       10
<PAGE>
 
Seller, respectively, they recognize that there may be certain assets and
liabilities that do not clearly fit into one category or the other that may be
identified between the date of this Agreement and the Closing Date or may be
identified after the Closing. In such case the parties will endeavor in good
faith to allocate any such asset or liability equitably between each other in
such a manner as to carry out the intent of this Agreement, including any such
transfer by Seller in accordance with Sections 2.1(c) and 2.2(c). As a general
principle, the parties agree that any such asset or liability that is incidental
to or a consequence of an asset or liability assigned to the Bank Business or
Trust Business will belong to the party receiving the related asset or
liability. Any other asset or liability that relates to both the Bank Business
and the Trust Business will be allocated between the parties based on the
relative benefit or burden derived from such asset or liability to the Bank
Business or Trust Business, except that if such relative benefit or burden
cannot be ascertained, then each party shall share equally in such benefit or
burden. If the parties are unable to agree on an allocation after a good faith
effort, the matter shall be referred to arbitration pursuant to Section 14.16.

intention of the parties that Target will operate the Banking Offices for its
own account until the close of business on the Closing Date, and that Purchaser
shall operate the Banking Offices, own the Bank Assets and assume the Bank
Liabilities from and after the close of business on the Closing Date.  To the
extent provided in Section 2.4 of the Stock Purchase Agreement, items of income
and expense shall be prorated as of the close of business on the Closing Date,
and settled between Target and Purchaser on the Closing Date, whether or not
such adjustment would normally be made as of such time. Items of proration not
capable of being settled at Closing shall be settled not later than thirty (30)
days after Closing unless otherwise agreed by the parties hereto.  Seller or
Purchaser shall promptly pay the amount due to the other party, as the case may
be, by wire transfer of immediately available federal funds to such account as
the party shall advise.

                    -------------------------                                
party of notice of the assertion of any claim or the commencement of any action,
suit or proceeding arising under this Agreement, such party ("Indemnified
Party") shall give written notice thereof to the other party ("Indemnitor") and
will thereafter keep the Indemnitor reasonably informed with respect thereto,
provided that failure of the Indemnified Party to give the Indemnitor prompt
notice as provided herein shall not relieve the Indemnitor of its obligations
hereunder except to the extent, if any, it shall have been prejudiced thereby.
In case any such action, suit or proceeding is brought against an Indemnified
Party, the Indemnitor shall be entitled to participate in (and, in its
discretion, to assume) the defense thereof with counsel satisfactory to the
Indemnified Party, provided, however, that the Indemnified Party shall be
entitled to participate in any such action, suit or proceeding with counsel of
its own choice at the expense of the Indemnitor if, in the good faith judgment
of the Indemnified Party's counsel, representation by the Indemnitor's counsel
may present a conflict of interest or that there may be defenses available to
the Indemnified Party which are different from or in addition to those available
to the Indemnitor. The Indemnitor will not settle any claim, action, suit or
proceeding which would give rise to the Indemnitor's liability under its
indemnity unless such settlement includes as an unconditional term thereof the
giving by the claimant or plaintiff of a release of the Indemnified Party, in
form and substance

                                       25
<PAGE>
 
satisfactory to the Indemnified Party and its counsel, from all liability with
respect to such claim, action, suit or proceeding. If the Indemnitor assumes the
defense of any claim, action, suit or proceeding as provided in this Section,
the Indemnified Party shall be permitted to join in the defense thereof with
counsel of its own selection and at its own expense. If the Indemnitor shall not
assume the defense of any claim, action, suit or proceeding, the Indemnified
Party may defend against such claim, action, suit or proceeding in such manner
as it may deem appropriate, provided that an Indemnified Party shall not settle
any claim, action, suit or proceeding which would give rise to the Indemnitor's
liability under its indemnity without the prior written consent of the
Indemnitor, which consent shall not be unreasonably withheld.

     Section 12.4.  Survival.  All indemnities contained in or made pursuant to
                    --------                                                   
this Agreement shall survive the Closing, until fifteen months after the Closing
Date, except as to any claim for which written notice shall have been given
prior to such date.

     Section 12.5.  Indemnity under the Stock Purchase Agreement.  If more than
                    --------------------------------------------               
one of the parties hereto who are also parties to the Stock Purchase Agreement
have claims, losses, liabilities, demands and obligations (including reasonable
legal fees and expenses) which they are entitled to assert directly against Sun,
they shall cooperate with each other to coordinate the filing of their claims of
indemnity to maximize their recovery and shall distribute the indemnity proceeds
in an equitable manner.

          (a) Except as specifically provided otherwise herein, Seller shall
     cause Target to assist Purchaser in the orderly transition of the
     operations of the Banking Offices and shall give such further assurances
     and execute, acknowledge and deliver all such instruments as may be
     necessary and appropriate to effectively vest in Purchaser title in the
     Bank Assets in the manner contemplated hereby; and

          (b) Except as specifically provided otherwise herein, Purchaser shall
     give such further assurances to Target and shall execute, acknowledge and
     deliver all such acknowledgments and other instruments and take such
     further action as may be necessary and appropriate to effectively relieve
     and discharge Target from any obligations remaining with respect to the
     Bank Liabilities of Target assumed by Purchaser hereunder.

Target relating to the Bank Business which each of them is acquiring. Each of
CB, LSB and MSB shall assume the obligations of Seller as "Purchaser Parent" and
"Purchaser" under Section 9.8 of the Stock Purchase Agreement and shall retain
such books and records for seven (7) years and permit access to them by Sun and
Seller during such period so as to fulfill the obligations thereunder.
Notwithstanding anything to the contrary contained herein the obligations of the
parties hereto under this Section shall be subject to all applicable laws
relating to the confidentiality of bank records.

     Section 13.3.  Servicing Rights.  The parties agree that the responsibility
                    ----------------                                            
for addressing any liability incurred by any of them with respect to loan
servicing contracts listed on Schedule 13.3  shall be delegated to CB, LSB or
                              -------------                                  
MSB in accordance with the Allocation Agreement, or in the event the Allocation
Agreement fails to address such matter, by Seller in accordance with the
principles of Section 5.4.  A proportionate share of any excess loan loss
reserves of CB, LSB and MSB received from Target (the amount of such excess
reserves shall be agreed to by the parties as of the Closing Date) shall be used
to compensate CB, LSB or MSB, as applicable, for any actual loss incurred with
respect to the loan servicing contract liability delegated to it.  Any loss
incurred in excess of the loan loss reserves, if any, shall be shared equally
among the parties.

each party shall pay all of its own out-of-pocket expenses in connection with
this Agreement, including appraisal, accounting, consulting, professional and
legal fees, if any, whether or not the transactions contemplated by this

environmental audits or other investigations, (ii) filing of any forms
(including without limitation tax forms) with governmental instrumentalities in
connection with the transfer of the Real Property or Personalty, and (iii)

pursuant to Section 5.3), applicable to or arising in connection with the
transfer, assignment or assumption of the Loans (and mortgages, financing

     Section 14.2.  Communications, Notices, etc.  Purchaser shall furnish to
                    ----------------------------

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

willful breach of any representation, warranty or covenant occurring or arising
prior to the date of termination, upon the occurrence of any of the following:

          (a) Upon mutual agreement of the parties;

          (b) Upon receipt by CB, LSB or MSB or Seller or Target of notice from

     whether CB, LSB or MSB, individually; or

          (c) Upon written notice by any party to the other parties, if the

party shall be liable to the other party or parties for out-of-pocket expenses

duties in accordance with the intent of this Agreement. The parties agree to
cooperate in making such modifications. No modification of any provision of this
Agreement or schedule shall be binding unless in writing and executed by all of
the parties to this Agreement. Performance of or compliance with any covenant
given herein or satisfaction of any condition to the obligations of either party
hereunder may be waived by the party to whom such covenant is given or whom such
condition is intended to benefit, except to the extent any such condition is
required by law; provided, any such waiver must be in writing.

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

14.18, that neither this Agreement nor any rights, privileges, duties or
obligations of the parties hereto may be assigned by any such party prior to the
Effective Time without the written consent of the other party hereto, and
provided further that in the case of any such assignment the assigning party
shall also remain responsible as a party hereto.

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

          (a) From and after execution hereof, the parties hereto shall keep

     contemplated hereby except (i) to the extent that the Agreement and such
     negotiations must be disclosed to obtain the Regulatory Approvals, (ii) for
     disclosure made in accordance with the terms and conditions of this
     Agreement, (iii) to the extent required by applicable law, or (iv) as

        -----------------------------------------------                         
        of Bank Parties to allocate the Bank Business between Bank Parties,
        respectively, Bank Parties recognize that there may be certain assets
        and liabilities that are not easily allocated between Bank Parties that
        may be identified between the date of this Agreement and the Closing
        Date or may be identified after the Closing. In such case, Bank Parties
        will endeavor in good faith to allocate any such asset or liability
        equitably between each other in such a manner as to carry out the intent
        of this Agreement. As a general principle, Bank Parties agree that any
        such asset or liability that is incidental to or a consequence of an
        asset or liability assigned to a Banking Office will belong to the Bank
        Party acquiring the related asset or liability. Any other asset or
        liability that relates to more than one Banking Office shall be
        allocated between Bank Parties based on the relative benefit or burden
        derived from such asset or liability to the Banking Offices except that
        if such relative benefit or burden cannot be ascertained, then Bank
        Parties shall share equally in such benefit or burden. If Bank Parties
        are unable to agree on an allocation after a good faith effort, the
        matter shall be referred to arbitration pursuant to Section 14.16 of the
        Purchase and Assumption Agreement.

     (a) Except as otherwise provided in this Agreement, in the event that Bank
         Parties become liable to PMTH or PMH pursuant to Article XII of the
         Purchase and Assumption Agreement, such liability shall be allocated to
         and paid by each Bank Party in proportion to the liability attributable
         to it. If the liability cannot be proportioned among Bank Parties, such
         liability will be allocated evenly among Bank Parties.

     (b) In the event that PMTH or PMH becomes liable to Bank Parties pursuant
         to Article XII of the Purchase and Assumption Agreement, the amount
         payable to Bank Parties by PMTH or PMH shall be allocated among Bank
         Parties in proportion to the losses incurred by each Bank Party for
         which such indemnification is being paid.

     (c) In the event that Sun becomes liable to Bank Parties pursuant to
         Article XIII of the Stock Purchase Agreement, the amount payable to
         Bank Parties by Sun shall be allocated among Bank Parties in proportion
         to the losses incurred by each Bank Party for which such
         indemnification is being paid.
