                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1)       BASIS OF PRESENTATION

           The consolidated financial statements of UST Corp. and its
           subsidiaries ("the Company") included herein have been prepared by
           the Company, without audit, pursuant to the rules and regulations of
           the Securities and Exchange Commission. Certain information and
           footnote disclosures normally included in financial statements
           prepared in accordance with generally accepted accounting principles
           have been condensed or omitted pursuant to such rules and
           regulations. The Company, however, believes that the disclosures are
           adequate to make the information presented not misleading. All prior
           period amounts included in this Form 10-Q have been restated to
           reflect the January 3, 1997 acquisition of Walden Bancorp, Inc. as a
           pooling of interests. Refer to Note 5 for a further discussion of
           acquisitions. The amounts shown reflect, in the opinion of
           management, all adjustments necessary for a fair presentation of the
           financial statements for the periods reported. These financial
           statements should be read in conjunction with the financial
           statements and the notes thereto included in the Company's Annual
           Report on Form 10-K for the fiscal year ended December 31, 1996.

           The results of operations for the three-months ended March 31, 1997
           and 1996 are not necessarily indicative of the results of operations
           for the full year or any other interim period.

(2)       RESERVE FOR POSSIBLE LOAN LOSSES

           Analysis of the reserve for possible loan losses for the three months
           ended March 31, 1997 and 1996 is as follows:

(4)        NET INCOME PER SHARE CALCULATION

           Net income per share is computed using the weighted average number of
           shares of common stock and common stock equivalents outstanding.
           Common stock equivalents consist primarily of dilutive stock options
           computed under the treasury stock method. Average dilutive common
           stock equivalents totaled 433,825 and 484,885 for the three-month
           periods ended March 31, 1997 and 1996, respectively.

           On March 3, 1997, the FASB issued SFAS No. 128, "Earnings Per Share."
           This Statement supersedes APB Opinion No. 15 regarding the
           presentation of earnings per share ("EPS") on the face of the income
           statement. SFAS No. 128 replaces the presentation of Primary EPS with
           a Basic EPS calculation that excludes the dilutive effect to common
           stock equivalents. The Statement requires a dual presentation of
           Basic and Diluted EPS, which is computed similarly to Fully Diluted
           EPS pursuant to APB Opinion No. 15, for all entities with complex
           capital structures. This Statement is effective for fiscal years
           ending after December 15, 1997 and requires restatement of all
           prior-period EPS data presented. The net income per share for the
           three months ended March 31, 1997 would not change under SFAS No 128.


(5)       ACQUISITIONS

           On January 3, 1997, the Company completed its acquisition of Walden
           Bancorp, Inc. ("Walden"), a $1.0 billion multi-bank holding company
           headquartered in Acton, Massachusetts. The transaction was accounted
           for as a pooling of interests and was structured as a tax-free
           exchange of 1.9 shares of the Company's common stock for each share
           of Walden common stock. The Company's outstanding stock increased by
           10,125,540 shares to a total of 28,144,163 shares on the date of
           acquisition. Based on the closing price of the Company's stock as of
           January 3, 1997, the market value of the shares exchanged totaled
           $207 million. Walden's two subsidiary banks, The Braintree Savings
           Bank and The Co-operative Bank of Concord operated a total of
           seventeen branches located in the Massachusetts counties of
           Middlesex, Norfolk and Plymouth. On April 18, 1997 The Co-operative
           Bank of Concord was merged into USTrust, the Company's principal
           banking subsidiary. The Braintree Savings Bank will be merged
           into USTrust on May 16, 1997. The following presentation reflects the
           line items on a historical basis for Walden and UST Corp. and on a
           pro forma combined basis assuming the merger was in effect for the
           periods presented.

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

       The following discussion should be read in conjunction with the financial
statements, notes, and tables included in the Company's Annual Report on Form
10-K for the fiscal year ended December 31, 1996. The discussion contains
certain forward-looking statements regarding the future performance of the
Company. All forward-looking information is inherently uncertain and actual
results may differ materially from the assumptions, estimates or expectations
reflected or contained in the forward-looking information. Please refer to
"Cautionary Statement Regarding Forward-looking Information" of this Form 10-Q
for a further discussion. All 1996 financial data included in this discussion
has been restated to reflect the January 3, 1997 acquisition of Walden Bancorp,
Inc. as a pooling of interests.

HIGHLIGHTS

       Net income for the quarter ended March 31, 1997, was $362 thousand, or
$0.01 per share, compared with $7.4 million, or $0.26 per share, for the same
period in 1996. First quarter 1997 results included a nonrecurring charge of
$2.8 million for certain nondeductible merger-related expenses and a pre-tax
charge of $11.8 million for restructuring expenses associated with the
acquisition of Walden Bancorp, Inc. ("Walden") completed during the quarter.
First quarter 1997 results were positively affected by the fourth quarter 1996
acquisition of 20 banking branches resulting in the assumption of $508 million 
in loans and $744 million in deposit and other liabilities from two banking
subsidiaries of BankBoston Corp. ("the Branch Purchase"). Also included in
first quarter 1997 earnings was a $1.8 million realized gain from the loans
held-for-sale portfolio. Excluding the effects of the nonrecurring charges,
net income for the 1997 first quarter was $10.3 million, or $0.36 per share.

       The aforementioned nonrecurring items reduced the return on average
equity and return on average assets to .49 percent and .04 percent,
respectively, from 11.00 percent and 1.01 percent, respectively, last year.
Excluding the nonrecurring charges of $14.6 million this quarter, return on
average equity and return on average assets were 13.9 percent and 1.18 percent,
respectively.

NET INTEREST INCOME ANALYSIS

       Net interest income on a fully taxable equivalent basis was $39.8 million
for the three months ended March 31, 1997, compared with $33.2 million in the
same quarter of 1996. The $6.6 million increase was largely due to the
additional volume of interest-earning assets and interest-bearing liabilities
acquired in the Branch Purchase.

       Average earning assets for the quarter were $3.309 billion, $526 million
higher than the same period a year ago. Average loan volume increased $544
million over the same quarter last year reflecting the loans acquired in the
Branch Purchase and loan growth over the past year. As shown in the table below,
the increase in loans and an increase in federal funds sold, partially reduced
by a $68 million decline in average securities, resulted in a $11.0 million
increase in interest income. Average interest-bearing liabilities increased $450
million to $2.722 billion primarily reflecting deposits acquired in the Branch
Purchase. This increase in liabilities added $3.2 million in volume-related
interest expense in the quarter. The net effect on net interest income from
changes in volume of interest-earning assets and interest-bearing liabilities
was an increase of $7.8 million for the three months ended March 31, 1997.



                                       9
<PAGE>   10
       The yield on average-earning assets decreased to 8.05 percent from 8.16
percent for the same quarter last year reflecting the effect on loan yield of
lower market interest rates and external pressure on loan pricing. Yield on
loans decreased 38 basis points from last year to 8.78 percent. The net effect
on interest income from a lower earning asset yield was a decrease of $1.8
million. The average cost of funds decreased 28 basis points to 3.85 percent.
This decrease reflects the favorable impact of low-cost deposits acquired in the
Branch Purchase. Rates on new deposit products have remained relatively level
since a year ago. The effect on total interest expense from changes in average
cost of funds from a year ago was a decrease of $673 thousand.

       This quarter's interest rate margin and spread increased to 4.88 percent
and 4.20 percent, respectively, from 4.79 percent and 4.03 percent,
respectively, in the first quarter of last year. The improvement was largely
attributed to the positive effect of higher loan volumes and low-cost deposits
acquired in the Branch Purchase which was only partially offset by the decrease
in loan yield. The net effect of rate changes on net interest income for the
three-month period ending March 31, 1997 compared to the same quarter last year
was a decrease of $1.1 million.
        
       The following table attributes changes in interest income and interest
expense to changes in interest rates and changes in the volume of
interest-earning assets and interest-bearing liabilities for the three months
ended March 31, 1997 when compared with the three months ended March 31, 1996.
Changes attributable to both rate and volume are allocated on a weighted basis.

NONINTEREST INCOME

       Noninterest income for the quarter increased $3.8 million to $12.4
million compared to the same period a year ago. This quarter reflects realized
gains on the loans held-for-sale portfolio of $1.8 million compared to a nominal
gain last year. Service charges on deposit accounts increased $684 thousand and
corporate services income, which includes merchant credit card income, increased
$844 thousand reflecting the favorable effect of the Branch Purchase and fee
income growth.

NONINTEREST EXPENSE

       Total noninterest expense increased $22.2 million compared to the same
quarter last year to $50.0 million. This quarter's nonrecurring acquisition and
merger-related expense and restructuring charges account for $14.6 million of
the increase. Merger expense of $2.8 million was primarily for professional
services paid in connection with the Walden acquisition transaction.
Restructuring charges of $11.8 million included expenses paid and provisions for
severance payments to former Walden executives and staff, write-offs of certain
Walden assets and contract buyouts, system conversion costs, and certain other
expenses associated with the integration of the Walden banking subsidiaries.
Salary and employee benefits expense and occupancy and equipment expense
increased $3.0 million and $1.0 million, respectively, to support the addition
of the twenty banking branches acquired in the fourth quarter of 1996. Merchant
credit card expense increased $560 thousand consistent with the increase in
merchant card income described above, and other noninterest expense, which is
detailed below, increased $3.5 million. Partially offsetting these expense
increases was a decrease of $485 thousand in foreclosed asset and workout
expense reflecting the reduced level of problem assets.

       As displayed in the table below, other noninterest expense increased $3.5
million to $10.5 million from the same quarter last year. Amortization of
intangibles increased $1.5 million reflecting the amortization of the premium
incurred in the Branch Purchase. Advertising and promotion increased $378
thousand reflecting the continuation of the fourth quarter 1996 product
promotions and the beginning of this year's advertising campaign, "THE other
BIG BANK." Service bureau and data processing costs increased $526 thousand
largely as a result of higher use of ATM's of nonaffiliated banks by the
acquired customers in the Branch Purchase. All other noninterest expense
increased $1.5 million reflecting replacement stationery and supplies with the
Company's new logo, increased checkbook expense due to free replacements
offered to deposit customers acquired in the Branch Purchase and increases in
other miscellaneous categories due to the operation of twenty additional
banking branches.

INCOME TAXES

       The Company recorded income taxes of $1.7 million compared with $4.5
million for the same quarter last year. The effective tax rate for the quarter
was 82.7 percent compared with 37.6 percent a year ago, the result of $2.8
million of merger-related charges included in noninterest expense that were
not deductible for tax purposes. Excluding these expenses, the effective tax 
rate would have approximated 39 percent.

        Included in other assets as of March 31, 1997, was a deferred tax asset
of approximately $16 million. The Company believes that it is more likely than
not that the benefit of this deferred asset will be realized.

ASSETS

       Total assets at March 31, 1997 were $3.539 billion, a decrease of $159
million from $3.698 billion at December 31, 1996. This decrease in asset size
was largely attributed to the restructuring of the securities portfolio
principally at the acquired Walden banks. Total securities decreased $84 million
to $744 million at March 31, 1997. Also, during the quarter, all of the $146
million in securities held-to-maturity at December 31, 1996 was redesignated as
securities available-for-sale. Federal funds sold decreased approximately $75
million and the entire $12 million loans held-for-sale portfolio at year-end
1996 was sold during the quarter. Intangible assets decreased $7 million as a
result of amortization during the quarter and a reallocation of the Branch
Purchase price based upon receipt of appraisals of certain assets acquired.
Total loans increased $20 million to $2.473 billion.

       The following table presents the composition of the loan portfolio:

</TABLE>


       The Company's commercial loan portfolios listed above totaled $1.159
billion at March 31, 1997, reflecting a small net increase of $4 million.
Excluding overdraft activity, commercial loans increased a net of $13 million
during the quarter. Commercial loans increased $141 million from a year ago.
Commercial loans acquired in the 1996 Branch Purchase totaled $111 million while
commercial loans sold in the fourth quarter 1996 sale of UST Bank/Connecticut,
a former banking subsidiary, were approximately $19 million. Excluding these
events, the commercial loan portfolios grew $49 million over the past year.

       Residential loans decreased $25 million during the quarter to $779
million due to normal amortization. Since the Company does not originate
residential mortgage loans, growth in this portfolio is not expected unless
through acquisition. The increase in residential loans from a year ago reflects
loans acquired in the 1996 Branch Purchase.

       The indirect automobile loan portfolio continues to experience strong
growth as planned. This portfolio grew 12 percent or $36 million this quarter to
$337 million. In comparison to a year ago, the portfolio has grown 54 percent,
or $119 million. These loans are subjected to the Company's credit quality
standards and are not what is referred to in the industry as "subprime" or high
risk automobile loans.

LIQUIDITY AND FUNDING

       Liquidity involves the Company's ability to raise or gain access to funds
in order to fulfill its existing and anticipated financial obligations. It may
be provided through amortization, maturity or sale of assets such as loans and
securities, liability sources such as increased deposits, utilization of the
Federal Home Loan Bank credit facility, purchased or other borrowed funds, and
access to the capital markets. The Company's securities portfolio is classified
entirely as available-for-sale, which provides the flexibility to sell certain
securities based upon changes in economic or market conditions, interest rate
risk and the Company's financial position and liquidity.

       At March 31, 1997, liquidity, which includes excess cash, funds sold and
unpledged securities, totaled approximately $417 million, or 12 percent of total
assets.

       The funds needed to support the Company's loan and securities portfolios
are provided through a combination of commercial and retail deposits and
short-term borrowings. Total deposits decreased $68 million during the quarter
to $2.788 billion. Noninterest-bearing deposits decreased $32 million since the
beginning of the year due to seasonal fluctuations which have normally occurred
during the first quarter of the year. Savings deposits, including NOW, money
market and regular savings, decreased $13 million to $1.332 billion. The savings
deposit balance also reflects a shift from NOW to money market deposits of
approximately $214 million this quarter. This was a result of an overnight
deposit sweep process recently implemented by the Company's subsidiary bank,
USTrust, which transfers certain NOW account balances to money market accounts
on a nightly basis then returns the balances to a NOW account status the
following morning. The effect of this process, which has no impact on an
individual customer's account status, is a reduction of the cash reserve
balances that are required to be maintained at the Federal Reserve Bank. This
process has become a customary procedure for most large institutions and has
Federal Reserve Board approval. Time certificates of deposit decreased $23
million during the quarter to $888 million. Short-term borrowings also
decreased during the quarter, $54 million to $424 million, consistent with the
reduction in federal funds sold and lower securities balance.
        
       As shown in the Consolidated Statements of Cash Flows, cash and cash
equivalents increased $707 thousand during the three-month period ended 
March 31, 1997. Cash used by operations resulted largely from the net increase
in other liabilities partially offset by the aggregate of operating income
items. Cash provided by investing activities was due to an excess of maturities
and sales of securities over cash used for securities purchases and increased
loan volume. Net cash used by financing activities was primarily due to
decreases in nontime and certificates of deposit and borrowings.
        
       At March 31, 1997, the parent Company had $3.4 million in cash and $4
million in short-term securities purchased under agreement to resell compared
with $.8 million and $14.0 million, respectively, at year end. The decrease in
excess funds was primarily due to the net of a $20 million capital contribution
to USTrust and the receipt of $12 million in dividends from the Walden banks
during the quarter.

INTEREST RATE RISK

       Volatility in interest rates requires the Company to manage interest rate
risk which arises from differences in the timing of repricing of assets and
liabilities. Management monitors and adjusts the difference between
interest-sensitive assets and interest-sensitive liabilities ("GAP" position)
within various time frames. An institution with more assets repricing than
liabilities within a given time frame is considered asset sensitive ("positive
GAP") and in time frames with more liabilities repricing than assets it is
liability sensitive ("negative GAP"). Within GAP limits established by the Board
of Directors, the Company seeks to balance the objective of insulating the net
interest margin from rate exposure with that of taking advantage of anticipated
changes in rates in order to enhance income. The Company's policy is to limit
its one-year cumulative GAP position to 2.5 times equity, presently equal to
approximately 20 percent of total assets. The Company manages its interest rate
GAP primarily by lengthening or shortening the maturity structure of its
securities portfolio.




                                       13
<PAGE>   14
       The Company's GAP presentation may not reflect the degrees to which
interest-earning assets and core deposit costs respond to changes in market
interest rates. The Company's rate-sensitive assets consist primarily of loans
tied to the prime rate and to a lesser extent the London Interbank Offered Rate
("LIBOR"). The following table summarizes the Company's GAP position at March
31, 1997. The majority of loans are included in 0-30 days as they reprice in
response to changes in the interest rate environment. Interest-bearing deposits
are classified according to their expected interest rate sensitivity. Actual
sensitivity of these deposits is reviewed periodically and adjustments are made
in the Company's GAP analysis that management deems appropriate. Securities and
noninterest-bearing deposits are categorized according to their expected lives
based on published industry prepayment estimates in the case of securities and
current management estimates for noninterest bearing deposits. Securities are
evaluated in conjunction with the Company's asset/liability management strategy
and may be purchased or sold in response to expected or actual changes in
interest rates, credit risk, prepayment risk, loan growth and similar factors.
The reserve for possible loan losses is included in the "Over 1 Year" category
of loans. At March 31, 1997, the one-year cumulative GAP position was negative
at $49 million, or approximately 1 percent of total assets.

CREDIT QUALITY AND RESERVE FOR POSSIBLE LOAN LOSSES

       At March 31, 1997 substandard loans were $26.5 million compared with
$37.7 million at December 31, 1996. Loans reported as substandard include loans
classified as Substandard or Doubtful as determined by the Company in its
internal credit risk rating profile. Under the Company's definition, Substandard
loans, which include nonaccruals, are characterized by the distinct possibility
that some loss will be sustained if the credit deficiencies are not corrected.
The Substandard classification, however, does not necessarily imply ultimate
loss for each individual loan so classified. Loans classified as Doubtful have
all the weaknesses inherent in Substandard loans with the added characteristic
that the weaknesses make collection of 100 percent of the assets questionable
and improbable.

       As shown in the table above, total nonperforming assets decreased $9.1
million since December 31, 1996 and $2.1 million from a year ago to $28.7
million. The level of nonperforming assets at quarter end continues to be within
the range of industry norms relative to the Company's size and total volume of
loans. The reserve for possible loan losses was relatively unchanged since year
end at $50.2 million. There was no provision for loan loss this quarter and net
chargeoffs were a nominal $49 thousand. The reserve coverage on nonaccrual loans
improved this quarter to 194.7 percent. The reserve to total period-end loans
remains at 2.0 percent.

       At March 31, 1997, total impaired loans were $18.4 million, comprised of
$.3 million that required a reserve for possible loan losses of $.3 million and
$18.1 million that did not require a related reserve. Impaired loans, as defined
in Statement of Financial Accounting Standards No. 114 ("SFAS No. 114"),
"Accounting by Creditors for Impairment of a Loan," are commercial and
commercial real estate loans recognized by the Company as nonaccrual and
restructured.

       The Company maintains a reserve for possible loan losses to absorb future
chargeoffs of loans and leases in the existing portfolio. The reserve is
increased when a loan loss provision is recorded in the income statement. When a
loan, or portion thereof, is considered uncollectible, it is charged against the
reserve. Recoveries on amounts previously charged off are added to the reserve
when collected. Adequacy of the reserve for possible loan losses is determined
using a consistent, systematic methodology which analyzes the size and risk of
the loan and lease portfolio on a monthly basis. Factors in this analysis
include historical loss experience and asset quality, as reflected by
delinquency trends, nonaccrual and restructured loans and the Company's credit
risk rating profile. Consideration is also given to the current and expected
economic conditions and, in particular, how such conditions affect the types of
credits in the portfolio and the market area in general. This analysis is
documented using a combination of numerical and qualitative analysis and
includes sensitivity testing and a written conclusion.

       No portion of the reserve is restricted to any loan or group of loans,
and the entire reserve is available to absorb future realized losses. The amount
and timing of realized losses and future reserve allocations may vary from
current estimates. An allocation of the reserve for possible loan losses to each
category of loans is presented below:

  * Consumer loans include indirect automobile installment loans, residential
    mortgages, home equity lines of credit, credit cards, check credit and other
    consumer loans.

      The reserve for possible loan losses was $50.2 million at March 31,
1997, consistent with the December 1996 year-end balance. The reserve was $18   
million lower than March 31, 1996 balance as a result of earnings credits
recorded through the provision for possible loan losses in the second and third
quarters of 1996. The unallocated portion of the reserve was 20 percent at
March 31, 1997 compared with 24 percent at year end. The decrease of 4
percentage points, or $1.6 million, reflects a reallocation of the reserve to
commercial loan categories at the Walden banks during the quarter.

CAPITAL AND DIVIDENDS

       The Company and its banking subsidiaries are subject to various
regulatory capital requirements administered by the federal banking agencies.
Failure to meet minimum capital requirements can initiate certain mandatory--and
possibly additional discretionary--actions by regulators that, if undertaken,
could have a direct material effect on the Company's financial statements. Under
capital adequacy guidelines and the regulatory framework for prompt corrective
action, the Company and its subsidiary banks must meet specific capital
guidelines that involve quantitative measures of assets, liabilities, and
certain off-balance sheet items as calculated under regulatory accounting
practices. The capital amounts and classifications are also subject to
qualitative judgments by the regulators about components, risk weightings, and
other factors.

       Quantitative measures established by regulation to ensure capital
adequacy require the Company and its banking subsidiaries to maintain minimum
amounts and ratios (set forth in the table below) of Total and Tier I capital
(as defined in the regulations) to risk-weighted assets (as defined), and of
Tier I capital (as defined) to average assets (as defined). Management believes,
as of March 31, 1997, that the Company and its subsidiary banks meet all of
their respective capital adequacy requirements.

       As a condition to Federal Deposit Insurance Corporation approval of
USTrust's fourth quarter 1996 Branch Purchase, USTrust was required to have a 
Tier I leverage capital ratio of not less than: (i) 4.8 percent, no later than  
ten days after consummation of the acquisition of the sixteen BayBank branches;
and (ii) 5 percent, no later than three months after consummation of the
acquisition of the BayBank branches and for a period of six months thereafter.
As of March 31, 1997, USTrust continued to be in compliance with the foregoing
provisions and the Company expects that these conditions will not have a
material adverse impact on the future operations of USTrust. During a period
from the consummation of the Branch Purchase in December 1996 until March 5,
1997, USTrust's Total capital to total risk-based assets ratio temporarily fell
below the requirement of an adequately capitalized bank. The parent Company
effected a $20 million capital contribution to USTrust on March 5, 1997 in
order to meet this requirement.

RECENT ACCOUNTING DEVELOPMENTS

       On June 30, 1996, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS No. 125"), "Accounting
for Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities." This statement provides accounting and reporting standards for
transfers and servicing of financial assets and extinguishments of liabilities.
The standards are based on consistent application of a financial components
approach that focuses on control. After a transfer of financial assets, an
entity recognizes the financial and servicing assets it controls and the
liabilities it has incurred, derecognizes financial assets when control has been
surrendered, and derecognizes liabilities when extinguished. This statement
provides consistent standards for distinguishing transfers of financial assets
that are sales from transfers that are secured borrowings. This statement is
effective for transactions occurring after December 31, 1996, and is to be
applied prospectively. This statement was adopted on January 1, 1997 and did not
have a material impact on the Company's financial condition or
results of operations.

       On March 3, 1997, the FASB issued SFAS No. 128, "Earnings Per Share."
This Statement supersedes APB Opinion No. 15 regarding the presentation of
earnings per share ("EPS") on the face of the income statement. Refer to Note 4
to the Notes to Consolidated Financial Statements for a further discussion.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

       The preceding Management's discussion contains certain forward-looking
statements. Moreover, the Company may from time to time, in both written reports
and oral statements by Company management, express its expectations regarding
future performance of the Company. These forward-looking statements are
inherently uncertain, and actual results may differ from Company expectations.
The Company disclaims any obligation to announce publicly future events or
developments which affect forward-looking statements. Risk factors that could
impact current and future performance include but are not limited to: (i)
changes in asset quality and resulting credit risk-related losses and expense;
(ii) adverse changes in the economy of the New England region, the Company's
primary market, which could further accentuate credit-related losses and
expenses; (iii) adverse changes in the local real estate market can also
negatively affect credit risk since most of the Company's loans are concentrated
in Eastern Massachusetts and a substantial portion of these loans have real
estate as primary and secondary collateral; (iv) an increasingly competitive New
England financial services marketplace, where a large number of bank
acquisitions and mergers has resulted in fewer but much larger and financially
stronger competitors which could alter Company expectations; (v) fluctuations in
market rates and prices can negatively affect net interest margin, asset
valuations and expense expectations; and (vi) changing regulatory requirements
of federal and state agencies could materially impact future operations of the
Company.

       In the ordinary course of operations, the Company and its subsidiaries
become defendants in a variety of judicial and administrative proceedings. In
the opinion of management, however, there is no proceeding pending, or to the

adverse change in the financial condition or results of operations of the
Company and its subsidiaries.
