item 1. business

general description of business

UST Corp. (the "Company"), a bank holding company registered with the Board of
Governors of the Federal Reserve System (the "Federal Reserve Board"), was
organized as a Massachusetts business corporation in 1967. The Company is also
subject to examination by, and is required to file reports with, the
Commissioner of Banks of the Commonwealth of Massachusetts (the "Massachusetts
Commissioner"). As of December 31, 1998, the Company's banking subsidiaries were
USTrust and United States Trust Company ("USTC"), each headquartered in Boston
and chartered under Massachusetts law. USTrust and USTC are sometimes hereafter
collectively referred to as the "Subsidiary Banks. " All of the capital stock of
the Subsidiary Banks is owned directly or indirectly by the Company. In
addition, the Company owns, directly or indirectly through its Subsidiary Banks,
all of the outstanding stock of seven active nonbanking subsidiaries, all
Massachusetts corporations: Firestone Financial Corp. ("Firestone") (and its
Canadian subsidiary, Firestone Financial Canada, Ltd.), UST Leasing Corporation,
UST Capital Corp., UST Realty Trust, Inc., UST Auto Lease Corp. and Cambridge
Trade Finance Corp. as well as seven subsidiaries which hold foreclosed real
estate and real estate owned by the Company and its subsidiaries and six
subsidiaries which are passive holders of securities. All of the subsidiaries,
except Firestone Financial Canada Ltd. (which was organized under the laws of
the Canadian province of Ontario) were organized under Massachusetts law.

     The Company engages in one line of business, that of providing financial
services through its banking and nonbanking subsidiaries. A broad range of
financial services is provided principally to individuals and small- and
medium-sized companies in New England including those located in low- and
moderate-income neighborhoods within the Company's defined Community
Reinvestment Act assessment area. In addition, an important component of the
Company's financial services is the provision of trust and money management
services to professionals, corporate executives, nonprofit organizations, labor
unions, foundations, mutual funds and owners of closely-held businesses most of
whom are located in the New England region.

     As of the close of business on December 31, 1998, the Company's total
assets were approximately $5.9 billion and USTrust, the lead bank, represented
more than 99 percent of the Company's consolidated assets.

the subsidiary banks

The Subsidiary Banks are engaged in a general banking business and accept
deposits which are insured by the Federal Deposit Insurance Corporation ("FDIC")
under the Bank Insurance Fund and the Savings Association Insurance Fund.
USTrust provides a full range of commercial and consumer financial services.
USTC, which has full banking powers and accepts deposits which are insured by
the FDIC, focuses its activities on providing trust, money management and
venture capital services.

recent developments

Pending Acquisition of Brewer & Lord LLP

On December 17, 1998, USTrust entered into an Acquisition Agreement with Brewer
& Lord LLP, and its limited partners, a Massachusetts limited liability
partnership headquartered in Norwell, Massachusetts and engaged in the insurance
agency business. Pursuant to the terms of the Acquisition Agreement, USTrust
will acquire Brewer & Lord for cash by causing a newly-formed Massachusetts
limited liability company to be merged with Brewer & Lord, with the limited
liability company as the surviving entity to be known as "Brewer & Lord LLC."
Through its nine offices, Brewer & Lord provides personal, commercial and
employee benefit-related insurance products to consumers and businesses located
primarily in Massachusetts. Subject to the receipt of required regulatory
approvals, including those of the Massachusetts Commissioner of Banks and the
Massachusetts Commissioner of Insurance, USTrust anticipates that it will
complete the acquisition of Brewer & Lord during the second quarter of 1999.

business services

The Subsidiary Banks provide a broad range of banking services including
deposit, investment, cash management, payroll, wire transfer, leasing, merchant
credit card and lending services throughout New England. Commercial and
industrial lending takes the form primarily of direct loans and includes lines
of credit, revolving credit, domestic and foreign letters of credit, term loans,
mortgage loans, receivable, inventory and equipment loans and other specialized
lending services. Furthermore, the Company provides additional services to small
business customers through utilization of government sponsored and assisted loan
programs. USTrust is certified by the SBA as a "Small Business Administration
Lender." Through Firestone and UST Leasing Corp., the Company provides small
business equipment finance and lease services. The Company also intends to begin
in 1999 to provide leasing services for "large ticket" equipment financing to
customers located both in New England and throughout the United States. USTC
provides deposit services and other banking services, but focuses its activities
on money management, trust and venture capital services. In 1998, the Company,
through a newly organized subsidiary, Cambridge Trade Finance Corp., began
offering short-term financing in connection with international transactions
involving import and export of goods. The Company provides a broad range of cash
management services to a number of municipalities and government agencies in
Massachusetts. At December 31, 1998, the combined lending limit to a single
borrower of USTrust was approximately $75 million.

consumer services

Consumer services are provided by the Subsidiary Banks to customers in their
geographic areas. These services include savings and checking accounts, NOW and
money market accounts, consumer loans, credit cards (through a private label
arrangement), ATM and debit cards, safe deposit box facilities, travelers'
checks and foreign exchange into several major foreign currencies. Consumer
loans include home equity loans and lines of credit, automobile loans, personal
loans and loans to finance education costs as well as open-ended credit. The
Company also provides residential mortgage origination services. Furthermore,
USTrust maintains a residential mortgage servicing capacity for its own
portfolio and for third parties. As of December 31, 1998, the aggregate
principal amount of mortgages serviced by the Company for its own account was
approximately $1.1 billion. The Company also offers automobile leasing services
to customers through UST Auto Lease Corp. Automobile loan and lease volume
increased substantially in 1998 and reached a level of approximately $1.0
billion as of December 31, 1998. The Subsidiary Banks currently have an
aggregate of 87 offices and the Company maintains an automated teller machine
system which, through membership in various networks, provides the Company's
customers with access to their accounts at locations throughout the world. Most
of the Company's proprietary ATM machines provide information to customers in
English, Spanish and Portuguese, and also provide information adapted for the
visually impaired. As of December 31, 1998, the Company operated a network of
117 ATMs. In addition, through its membership in the SUM surcharge free network,
USTrust customers have access to almost 1,200 ATMs in Massachusetts at which a
surcharge is not imposed on USTrust customers.

investment services

The Investment Group located at USTrust was formed in 1994. The Investment Group
utilizes the services of Commonwealth Financial Network, an unaffiliated,
licensed broker-dealer, and offers to customers investments in mutual funds
(whose investments are managed by nonaffiliated third parties), Treasury Bills,
Treasury Notes, corporate bonds, state, federal and municipal bonds and variable
annuities as well as discount brokerage services.

real estate loans and services

The Subsidiary Banks and UST Realty Trust, Inc., a real estate investment trust
(REIT), provide a broad range of industrial and commercial real estate lending
services and other related financial products. The Company also provides real
estate construction loans to developers of projects in the cities and towns
served by USTrust's branch system. In addition, as previously noted, USTrust is
engaged in residential mortgage origination and servicing.

asset and money management and trust services

Asset and money management, custodial and trust services are provided by USTC.
In addition, USTC provides services as executor, administrator and trustee of
estates and acts, under the terms of agreements, in various capacities such as
escrow agent, bond trustee and trustee and agent of pension, profit sharing and
other employee benefit trusts. At December 31, 1998, the total assets under
management of USTC were approximately $3.5 billion. Approximately 30% of total
assets under management are those of clients who have requested that their
assets be managed with specified social as well as financial investment
objectives in mind. USTC also serves as investment adviser to a balanced mutual
fund, the Boston Balanced Fund.

securities portfolios maintained by the company

The Subsidiary Banks, both directly and through wholly-owned Massachusetts
securities corporations, maintain securities portfolios consisting primarily of
U.S. Treasury, U.S. Government Agency, and corporate and municipal securities.
The Subsidiary Banks own an aggregate of six Massachusetts securities
corporations. As Massachusetts securities corporations, these subsidiaries make
exclusively passive investments and serve the Company by buying, selling,
dealing in and holding securities eligible for investment by the Subsidiary
Banks

     All of the Company's securities are deemed "available-for-sale" which
enhances the liquidity position of the Company and allows for flexibility in
management of interest rate risk. The securities portfolios of the Subsidiary
Banks also include certain other equity investments to the extent allowed within
limits prescribed by Massachusetts and federal law. Such investments currently
include, among others, equity interests in the Massachusetts Housing Investment
Corporation's Limited Partnership Equity Fund for Affordable Housing. The
Treasury Division of the Company provides securities portfolio advisory services
to the Company's Subsidiary Banks. USTrust is also a member of the Federal Home
Loan Bank of Boston. This membership provides USTrust with access to an
additional source of funds.

principal nonbanking subsidiaries

Firestone Financial Corp. organized in 1965 and which became a subsidiary of
USTrust in 1997, provides small business equipment financing services to
companies headquartered throughout the United States. Firestone's principal
market consists of small businesses that operate various types of coin-operated
amusement equipment and vending machines, as well as owners/operators of
dry-cleaning, coin-operated laundry equipment and amusement rides. Firestone
also provides similar services to Canadian companies through its wholly-owned
subsidiary, Firestone Financial Canada Ltd., a Canadian entity. As of December
31, 1998, Firestone's total assets were approximately $89 million.

     UST Leasing Corporation, a subsidiary of USTrust organized in 1987,
provides a broad range of equipment leasing services to corporations
headquartered throughout the United States. UST Leasing Corporation offers a
line of leasing products designed to meet the needs of the Company's small
business customers and other business entities with similar needs. As of
December 31, 1998, UST Leasing Corporation's total assets were approximately $80
million.

     UST Auto Lease Corp., a subsidiary of USTrust organized in 1997, provides
automobile leasing services to consumers and corporations headquartered
throughout New England. As of December 31, 1998, UST Auto Lease Corp.'s total
assets were approximately $97 million.

     UST Realty Trust, Inc., an indirect subsidiary of USTrust, was organized in
1998. It functions as a real estate investment trust (REIT) which holds, and may
from time to time originate, real estate loans and participations in such loans.

     UST Capital Corp., organized in 1961 and acquired by the Company in 1969,
is a subsidiary of USTC and is a licensed Small Business Investment Company. It
specializes in equity and long-term debt financing for growth-oriented
companies.

     Cambridge Trade Finance Corp., organized in 1998, is a direct subsidiary of
the Company. It is primarily engaged in short-term financing of international
transactions involving import and export of goods.

competitive conditions

The Company's banking and nonbanking subsidiaries face substantial competition
throughout Massachusetts. This competition is provided by commercial banks,
savings banks, credit unions, consumer finance companies, mortgage companies,
insurance companies and agencies, mutual funds, government agencies, investment
management companies,


                                        5
<PAGE>   6

investment advisors, brokers and investment bankers. Most of these entities are
actively engaged in marketing various types of loans, deposits, investment
products and other financial services. Quality of service to customers, price of
products, breadth of its range of products and services and ease of
accessibility to facilities are among the principal methods of meeting
competition in the banking and financial services industries.

supervision and regulation of the company and its subsidiaries

general

As a bank holding company registered under the Bank Holding Company Act of 1956,
as amended (the "BHC Act"), the Company is subject to substantial regulation and
supervision by the Federal Reserve Board. As state-chartered banks, the
Subsidiary Banks are subject to substantial regulation and supervision by the
FDIC and the applicable state bank regulatory agency. Such regulatory oversight
is often intended primarily for the protection of depositors or is aimed at
carrying out broad public policy goals that may not be directly related to the
financial services provided by the Company and its subsidiaries. Supervision,
regulation and examination of the Subsidiary Banks by the bank regulatory
agencies is not intended for the protection of the Company's security holders.
Federal and state banking and other laws impose a number of requirements and
restrictions on the business operations, investments and other activities of
depository institutions and their affiliates.

general supervision and regulation

The Company, as a bank holding company under the BHC Act, is registered with the
Federal Reserve Board and is regulated under the provisions of the BHC Act.
Under the BHC Act the Company is prohibited, with certain exceptions, from
acquiring direct or indirect ownership or control of more than 5 percent of the
voting shares of any company which is not a bank and from engaging in any
business other than that of banking, managing or controlling banks or furnishing
services to, or acquiring premises for, its Subsidiary Banks, except that the
Company may engage in, and own voting shares of companies engaging in, certain
activities determined by the Federal Reserve Board, by order or by regulation,
to be so closely related to banking or to managing or controlling banks "as to
be a proper incident thereto."

     The Company is required by the BHC Act to file with the Federal Reserve
Board an annual report and such additional reports and notices as the Federal
Reserve Board may require. The Federal Reserve Board also makes periodic
inspections of the Company and its subsidiaries. The BHC Act requires every bank
holding company to obtain the prior approval of the Federal Reserve Board before
it may acquire substantially all of the assets of any bank, or ownership or
control of any voting shares of any bank, if, after such acquisition, it would
own or control, directly or indirectly, more than 5 percent of the voting shares
of such bank.

     Because the Company is also a bank holding company under the Massachusetts
General Laws, the Massachusetts Commissioner has authority to require certain
reports from the Company from time to time and to examine the Company and each
of its subsidiaries. The Massachusetts Commissioner also has enforcement powers
designed to prevent banks from engaging in unfair methods of competition or
unfair or deceptive acts or practices involving consumer transactions. Prior
approval of the Massachusetts Board of Bank Incorporation is also required
before the Company may acquire any additional banks located in Massachusetts or
in other jurisdictions.

     The location of nonbank subsidiaries of the Company is not restricted
geographically under the BHC Act. The Riegle-Neal Interstate Banking and
Branching Act of 1994 ("the Riegle-Neal Act") permits adequately capitalized and
managed bank holding companies to acquire control of banks in any state.
Additionally, as of June 1, 1997, the Riegle-Neal Act authorizes banks to branch
across state lines, provided that individual states did not elect to "opt out"
of interstate banking entirely. In 1996, Massachusetts adopted legislation (the
"Massachusetts Interstate Act") pursuant to which Massachusetts "opted in" to
interstate banking. The Massachusetts Interstate Act also allows Massachusetts
banks to establish and maintain branches through a merger or consolidation with
or by the purchase of the whole or any part of the assets or stock of any
out-of-state bank or through de novo branch establishment in any state other
than Massachusetts so long as such state permits Massachusetts banks to operate
in the same manner in such state.

     The Subsidiary Banks, whose deposits are insured by the FDIC, and the
subsidiaries of such banks are subject to a number of regulatory restrictions,
including certain restrictions upon: (i) extensions of credit to the Company and
the Company's nonbanking affiliates (collectively with the Company, the
"Affiliates"); (ii) the purchase of assets from


                                        6
<PAGE>   7

Affiliates; (iii) the issuance of a guarantee or acceptance of a letter of
credit on behalf of Affiliates; and (iv) investments in stock or other
securities issued by Affiliates or acceptance thereof as collateral for an
extension of credit. In addition, all transactions among the Company and its
direct and indirect subsidiaries must be made on an arm's length basis and
valued on fair market terms. During those periods when assessments are made by
the FDIC to banks placed in the same risk category as the Subsidiary Banks, the
Subsidiary Banks pay deposit insurance premiums to the FDIC.

     Federal Reserve Board policy requires bank holding companies to serve as a
source of strength to their subsidiary banks by standing ready to use available
resources to provide adequate capital funds to subsidiary banks during periods
of financial stress or adversity. A bank holding company also can be liable
under certain provisions of the Federal Deposit Insurance Corporation
Improvement Act of 1991 ("FDICIA") for the capital deficiencies of an
undercapitalized bank subsidiary. In the event of a bank holding company's
bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, the trustee will be
deemed to have assumed and is required to cure immediately any deficit under any
commitment by the debtor to any of the federal banking agencies to maintain the
capital of an insured depository institution, and any claim for breach of such
obligation will generally have priority over most other unsecured claims. Under
the cross-guarantee provisions of the Federal Deposit Insurance Act, if any or
all of the Subsidiary Banks were placed in conservatorship or receivership, the
Company, as direct or indirect sole stockholder, would likely lose its
investment in the applicable Subsidiary Bank or Subsidiary Banks, and, in
addition, its investment in its other Subsidiary Bank or Subsidiary Banks would
be at risk.

     In addition, under both Section 106 of the 1970 Amendments to the BHC Act
and regulations which have been issued by the Federal Reserve Board, the Company
and its subsidiaries are prohibited from engaging in certain tie-in arrangements
in connection with any extension of credit, lease or sale of any property or the
furnishing of any service. Various consumer laws and regulations also affect the
operations of the Subsidiary Banks.

     The Subsidiary Banks, which are chartered under Massachusetts law, are
subject to federal requirements to maintain cash reserves against deposits, and
to State mandated restrictions upon the nature and amount of loans which may be
made by the banks (including restrictions upon loans to "insiders" of the
Company and its Subsidiary Banks) as well as to restrictions relating to
dividends, investments, branching and other bank activities.

     FDICIA prescribes the supervisory and regulatory actions that will be taken
against undercapitalized insured depository institutions for the purpose of
promptly resolving problems at such institutions at the least possible long-term
loss to the FDIC. Five categories of depository institutions have been
established by FDICIA in accordance with their capital levels: "well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized," and "critically undercapitalized." The federal banking
agencies have adopted uniform regulations to implement the prompt regulatory
action provisions of FDICIA.

     FDICIA requires the appropriate regulatory agencies to take specific
actions against significantly undercapitalized institutions and undercapitalized
institutions that fail to submit acceptable capital restoration plans. An
undercapitalized institution is required to submit a capital restoration plan
for acceptance by the appropriate federal banking agency and will be subject to
close monitoring of both its condition and compliance with, and progress made
pursuant to, its capital restoration plan. An institution that fails to submit
an acceptable plan may be placed into conservatorship or receivership unless its
capital restoration plan is accepted. An undercapitalized institution will also
be subject to restrictions on asset growth, acquisitions, branching, new
activities, capital distributions and the payment of management fees. As of
December 31, 1998 both USTrust and USTC qualified as "well capitalized." (For
further information regarding the Company's and the Subsidiary Banks'
capitalization, please refer to Note 17 to Consolidated Financial Statements of
this Form 10-K.)

     An insured institution that receives a less-than-satisfactory rating for
capital adequacy, asset quality, management, earnings, liquidity or sensitivity
to market risk may be deemed by its appropriate federal banking regulator to be
engaging in an unsafe or unsound practice for purposes of issuing an order to
cease and desist or to take certain affirmative actions. If the unsafe or
unsound practice is likely to weaken the institution, cause insolvency or
substantial dissipation of assets or earnings or otherwise seriously prejudice
the interest of depositors or the FDIC, a receiver or conservator could be
appointed. Finally, subject to certain exceptions, FDICIA requires critically
undercapitalized institutions to be placed into receivership or conservatorship
within 90 days after becoming critically undercapitalized.

     The status of the Company as a registered bank holding company does not
exempt it from certain federal and state laws and regulations applicable to
corporations generally, including, without limitation, certain provisions of the
federal securities laws and the Massachusetts corporate laws. Federal bank
regulatory agencies, including the Federal Reserve Board and the FDIC, have
broad enforcement powers to restrict the activities of financial institutions,
and to impose or seek the imposition of civil and/or criminal penalties upon
financial institutions, the individuals who manage or control such institutions
and "institution affiliated parties" of such entities.

     Pursuant to the Federal Community Reinvestment Act ("CRA") and similar
provisions of Massachusetts law, regulatory authorities review the performance
of the Company and its Subsidiary Banks in meeting the credit needs of the
communities served by the Subsidiary Banks. The applicable regulatory
authorities consider compliance with this law in connection with applications
for, among other things, approval of branches, branch relocations and
acquisitions of banks and bank holding companies. Currently the FDIC's CRA
rating of USTrust is "outstanding"; the FDIC does not rate USTC which it regards
as a "special purpose" bank. The Massachusetts Commissioner currently has given
USTrust a CRA rating of "outstanding" and USTC a CRA rating of "satisfactory."

     In 1998, the Massachusetts Legislature adopted legislation which, for the
first time, authorizes Massachusetts chartered banks, such as the Subsidiary
Banks, to sell a broad range of insurance products. Shortly after the enactment
of this legislation and the promulgation of the enabling regulations, USTrust
announced its proposed acquisition of Brewer & Lord LLP. See "Recent
Developments - Pending Acquisition of Brewer & Lord LLP" above.

     From time to time various proposals are made in the United States Congress,
as well as state legislatures, which would alter the powers of, and place
restrictions on, different types of bank organizations as well as bank and
nonbank activities. Such legislative proposals include proposals related to
expansion of bank powers and increased consumer compliance disclosure
requirements. From time to time, federal legislation is proposed which, if
adopted, would grant bank holding companies broader powers with respect to
insurance and securities activities. Under proposed federal legislation, broader
cross-ownership would be authorized among banking, insurance and securities
companies. At this time it is unclear whether such legislation (in any form)
will be adopted in the near term.

     Over the past several years, the federal and state banking regulatory
agencies have issued guidance to the banking industry with respect to
appropriate measures which financial institutions should take to address risks
associated with the so-called "Year 2000" issue. In 1998 and 1999, the agencies
performed and are continuing to perform on-site visitations to determine each
bank or bank holding company's Year 2000 readiness. Failure to address any Year
2000 readiness deficiencies and concerns raised by the bank regulatory agencies
could have material adverse consequences to the Company. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations - Year
2000" for a further discussion of these matters.

governmental policies, economic conditions and credit risk concentration

The earnings and business of the Company's subsidiaries are and will be affected
by a number of external influences, including general economic conditions in the
United States and particularly in New England and the policies of various
regulatory authorities of the United States, including the Federal Reserve
Board. The Federal Reserve Board regulates the supply of money and of bank
credit to influence general economic conditions within the United States and
throughout the world. From time to time, the Federal Reserve Board takes
specific steps to dampen domestic inflation and to control the country's money
supply. The instruments of monetary policy employed by the Federal Reserve Board
for these purposes (including the level of cash reserves, which banks, including
nonmember banks such as the Subsidiary Banks, are required to maintain against
deposits) influence in various ways the interest rates paid on interest-bearing
liabilities and the interest received on earning assets, and the overall level
of bank loans, investments and deposits. During 1998, the Massachusetts economy
was extremely robust: employment levels remained high; interest rates were at
historically low levels; levels of disposable income were high and capital
expenditures were strong. There can be no assurance that these strong local
economic conditions will continue. In addition, the impact upon the future
business and earnings of the Company of prospective economic conditions
throughout the United States, and of the policies of the Federal Reserve Board
as well as other federal regulatory authorities, cannot be predicted accurately.

     During the period 1990 through 1993, the Company's primary loan market, the
New England region, suffered from a weak economic environment. The economic
climate contributed to a decline in real estate values and adversely affected
the net worth of certain borrowing customers of the Subsidiary Banks and the
Company's collateral position with respect to certain loans. The New England
regional economy, including the Company's principal markets, improved in the
mid-1990's, which aided the Company's loan workout efforts over the past several
years.

     Most of the Company's loans outstanding are from borrowers located in its
Community Reinvestment Act delineated communities in Massachusetts and a
substantial portion of these loans are various types of real estate loans; still
others have real estate as additional collateral. At year-end 1998, the
Company's exposure to credit risk from borrowers who had real estate as their
primary collateral support included $1.8 billion of loans.

general

No significant portion of the loans or deposits of any of the Company's Banking
Subsidiaries results from one or several accounts, the loss of which would
materially affect its business. The Company does not experience significant
seasonal fluctuations in its business. At December 31, 1998, The Federal Home
Loan Bank of Boston was a significant provider of funds to the Company. The
Company, however, does not believe that it would experience serious difficulty,
at this time, if it were required to find a source of funds to replace The
Federal Home Loan Bank of Boston.

employees

As of December 31, 1998, the Company and its subsidiaries had approximately
2,100 full-time and part-time employees.

item 2. properties

USTrust owns and occupies a twelve-story, 119,456 square foot brick and steel
building constructed in 1915 and located at Government Center, 30-40 Court
Street, Boston, Massachusetts, which houses the banking premises of USTrust,
USTC and the offices of the Company and most of its nonbanking subsidiaries.

     The Company currently leases a three-story brick office building of
approximately 37,900 square feet at 196 Broadway, Cambridge, Massachusetts, all
of which is used by USTrust, as well as 34,423 square feet in an adjacent office
tower at 141 Portland Street, Cambridge, Massachusetts. USTrust also leases
approximately 26,080 square feet of space at 25-55 Court Street, Boston,
Massachusetts, which is used primarily to house staff support services. In
addition, USTrust leases 30,000 square feet at 315 University Avenue, Westwood,
Massachusetts to house its consumer lending staff. The Company also owns a
66,000 square foot building at 212 Elm Street, Somerville, Massachusetts and a
43,400 square foot building at 716 Main Street, Waltham, Massachusetts, each of
which is used to house both a branch and support staff functions for the
Company.

     All of USTrust's branches are located in Eastern Massachusetts. Of its 87
branches, 44 locations are owned by USTrust and the remaining branch offices of
USTrust occupy leased premises.

     The 1999 annual leasehold commitment for all premises leased by the
Company's subsidiaries, totals approximately $8.3 million not including expenses
related to tax or maintenance escalation provisions. Refer to Note 19 to the
Notes to Consolidated Financial Statements of this Form 10-K.

     In March 1999 the Company completed its due diligence with respect to the
proposed purchase of a new 123,000 square foot operations center at 20 Cabot
Road, Medford, Massachusetts. The results of that due diligence were
satisfactory and the Company expects to complete the purchase of the foregoing
property in mid-1999. Subsequent to that purchase, late in 1999, the Company
plans to sublease most of the space currently occupied by USTrust at the
Cambridge, Massachusetts locations discussed above.

item 3. legal proceedings

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
knowledge of management threatened, which is likely to result in a material
adverse change in the financial condition or results of operations of the
Company and its subsidiaries.

item 4. submission of matters to a vote of security holders

None.

     The number of holders of record of common stock of the Company was 3,853 at
December 31, 1998.

     The Company declared cash dividends totaling $0.38 per share to each holder
of its common stock in 1997, and $0.54 per share to each holder of its common
stock in 1998. The amounts of the foregoing dividends have been restated to

upon the financial condition and earnings of the Company and its subsidiaries,
their need for funds and other factors, including applicable government
regulations and the absence of regulatory objection.

item 7. 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 elsewhere in this Form 10-K for the
fiscal year ended December 31, 1998. Certain amounts reported for prior periods
have been reclassified to conform to the 1998 presentation. All applicable
prior-period financial data presented has been restated to reflect the 1998
acquisitions of Somerset Savings Bank ("Somerset") and Affiliated Community
Bancorp, Inc. ("Affiliated"), and the 1997 acquisitions of Walden Bancorp, Inc.
("Walden") and Firestone Financial Corp. ("Firestone") as poolings of interests.
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" in this Form 10-K for a further discussion.

highlights

For the third consecutive year, the Company's acquisition activities continued
to significantly impact its financial condition and results of operations. In
1998, the Company completed the acquisitions of Somerset, a $524 million
Massachusetts savings bank, and Affiliated, a $1.1 billion multi-bank holding
company. Also during the year, Somerset and the subsidiary banks of Affiliated
were merged with and into USTrust, the principal banking subsidiary of the
Company. In December 1998, the Company announced the execution of a definitive
agreement to acquire Brewer & Lord LLP, an eastern Massachusetts-based
independent insurance agency. Refer to Note 2 to the Notes to Consolidated
Financial Statements for a further discussion of acquisitions.

     Net income for the year ended December 31, 1998, was $55.3 million, or
$1.28 per diluted share, compared with $50.2 million, or $1.18 per diluted share
last year. Results included merger-related and restructuring charges of $19.6
million in 1998 and $16.2 million in 1997. Excluding these merger-related and
restructuring charges in both years, 1998 after-tax income would have been $70.5
million, or $1.63 per diluted share, an increase of 14 percent over the $61.7
million, or $1.44 per diluted share last year. This year's earnings reflect a
$21.8 million, or 9 percent increase in net interest income due to earning asset
growth and favorable changes in liability mix and funding costs. Noninterest
income improved $7.1 million, or 17 percent, due to net realized gains from the
sale of securities and loans of $3.6 million and higher income from several
fee-based services. Asset quality continued to improve, and as a result, the
provision for possible loan loss decreased almost $1 million this year from
1997. Noninterest expense, excluding merger-related and restructuring charges,
increased $15.6 million. This reflects $5.4 million in Year 2000 readiness
expense and higher operating costs due to volume growth during a year of
transition as operating systems and processes of the acquired banks were
converted to USTrust.

                    financial condition at december 31, 1998

assets

Total assets at December 31, 1998 were $5.901 billion, a 7 percent increase from
$5.533 billion a year ago. Loans reflect growth of 8 percent, or $329 million to
$4.296 billion at year end. Growth in other assets reflects an investment in
bank-owned life insurance of $30 million. The investment provides life insurance
to the Company on certain executives and a favorable tax-exempt cash flow. Total
securities increased $82 million to $1.290 billion. Partially offsetting these
increases in assets was a $73 million decrease in federal funds sold to help
fund the growth in other earning assets.

(1)  Indirect automobile installment loans represent loans that have been
     underwritten by the Company and originated, or sourced, by qualifying
     in-market automobile dealers. Automobile loans originated directly by the
     Company are not significant and are included with other consumer loans.

(2)  Excluded from the loan balances at December 31, 1997, 1996 and 1995 were
     $4.0 million, $12.4 million and $14.2 million, respectively, in loans
     held-for-sale, recorded at net realizable value and classified in other
     assets.
- --------------------------------------------------------------------------------

     The Company's commercial loan and lease portfolios totaled $2.044 billion
at December 31, 1998, an increase of 15 percent, or $260 million over 1997. The
increase was due to net new loan originations and advances during the year and
the purchase of an $80 million commercial loan portfolio in the first quarter.
This year's commercial loan and lease growth was a strong improvement over the
1997 growth of 3 percent, or $56 million.

     Residential loans decreased $286 million during 1998 to $1.085 billion due
to high levels of prepayment and normal amortization. The low interest rate
environment accelerated prepayment in this portfolio. A component of the
Affiliated acquisition was the residential mortgage loan origination division of
Lexington Savings Bank. Following the merger of Lexington with and into USTrust
during the fourth quarter of 1998, the Company began the expansion of
residential mortgage origination activities throughout all of USTrust branch and
retail service outlets. Prior to this acquisition, the Company's subsidiary
banks did not originate residential mortgages.

     The indirect automobile loan portfolio experienced continued strong growth
in 1998. This portfolio totaled $910 million at December 31, 1998, and reflects
growth of 50 percent, or $304 million, this year compared with $303 million, in
1997. Management expects both the dollar volume and rate of growth in this
portfolio to moderate in 1999. The origination of these loans is subject to the
Company's credit quality standards and these loans are not what is referred to
in the industry as "subprime" automobile loans.

     Beginning in the second half of 1997, indirect automobile lease financing
was made available through existing client automobile dealers. This portfolio
totaled $98 million at December 31, 1998, compared with $26 million a year ago.
These leases are also subject to the Company's credit quality standards and are
not "subprime" automobile leases.

</TABLE>

     The Company does not have an automatic rollover (renewal) policy for
maturing loans. Renewal requests are reviewed and approved in substantially the
same manner as applications by new customers for extensions of credit.
Additionally, any renewal of a loan rated Substandard or lower in the Company's
credit risk rating profile, requires the Workout Loan Department head approval
and for certain size loans and circumstances, the approval of the Senior Credit
Committee and Board of Directors.

Securities

Securities totaled $1.290 billion at December 31, 1998, an increase of $82
million from a year earlier. The increase reflects net purchases of $351 million
in 15-year U.S. Agency mortgage-backed securities while other securities
decreased $277 million. Upon the completion of the Somerset and Affiliated
acquisitions, the Company redesignated a total of $168 million of former
Somerset and Affiliated securities from held-to-maturity to securities
available-for-sale, consistent with the Company's historical policy of carrying
all securities as available-for-sale.

     Included in the increase in securities was an increase in unrealized gain
on securities available-for-sale of $8 million to $13 million at December 31,
1998. The improvement reflects favorable pricing changes in bond and certain
equity investments during the year. Refer to Note 1 to the Notes to Consolidated
Financial Statements for a further discussion of the unrealized valuation
adjustment to market value of securities available-for-sale.

     The change in the market value of securities available-for-sale also had
the effect of increasing stockholders' investment by $4 million. The unrealized
gain reported as part of stockholders' investment was $8 million, net of tax at
December 31, 1998.

     The Company has a policy of purchasing securities primarily rated A, or
better, by Moody's Investors Services and U.S. Government securities to minimize
credit risk. As of December 31, 1998, $1.0 billion of the Company's
mortgage-backed securities were issued by agencies or sponsored agencies of the
U.S. Government, and $4 million were investment grade mortgage-backed securities
issued by nongovernment agencies. At December 31, 1998, none of the Company's
mortgage-backed securities would be classified as "high risk" under Federal
Financial Institutions Examination Council guidelines. All securities, however,
carry interest rate risk which affects their market value such that as market
yields increase, the value of the Company's securities declines and vice versa.
Additionally, mortgage-backed securities carry prepayment risk where expected
yields may not be achieved due to an inability to re-invest the proceeds from
unexpected prepayment at comparable yields. Moreover, such mortgage-backed
securities may not benefit from price appreciation in periods of declining rates
to the same extent as the remainder of the portfolio. Refer to Note 1 to the
Notes to Consolidated Financial Statements, "Summary of Significant Accounting
Policies" of this Form 10-K for a further discussion of prepayment risk. At
December 31, 1998, the aggregate fair value of any individual issuer's
securities,

other than an agency or sponsored agency of the U.S. Government, did not exceed
10 percent of the Company's stockholders' investment. The following table sets

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 available-for-sale, liability sources such as increased deposits,
utilization of the Federal Home Loan Bank credit facility, borrowings from the
Federal Reserve Bank of Boston, 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 December 31, 1998, liquidity, which includes excess cash, federal funds
sold and unpledged securities, totaled approximately $758 million, or 13 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 increased $68 million, or 2 percent,


                                       15
<PAGE>   16

to $4.234 billion since December 31, 1997. Noninterest-bearing deposits
increased $65 million while savings deposit growth, which includes NOW, money
market and regular savings, increased $216 million. These areas of deposit
growth reflect the Company's innovative deposit products and promotional
initiatives, as well as the synergies of a larger branch network, augmented by
acquisitions. Certificates of deposit decreased $214 million as the Company is
intentionally less competitive with these higher cost products. The savings
deposit balances also reflect a shift from NOW to money market deposits of
approximately $60 million since the beginning of the year. This reflects the
addition of the Affiliated banks and Somerset to USTrust's overnight deposit
sweep process. This process transfers certain NOW account balances to money
market accounts on a nightly basis and 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 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. Short-term and other borrowings, which consist
principally of federal funds purchased, securities sold under agreement to
repurchase, and borrowings from the Federal Home Loan Bank, increased $246
million to $1.062 billion to support loan growth and securities purchases.

     As shown in the Consolidated Statements of Cash Flows, cash and cash
equivalents increased $6 million during 1998. Cash provided by operations
resulted largely from net income earned during the year. Cash used by investing
activities was due to an excess of purchases of securities and increased loan
volume over cash provided by securities sales and maturities, and reduction in
federal funds sold. Cash provided by financing activities was provided primarily
by increases in nontime deposits and borrowings, partially offset by reductions
in certificates of deposit.

     At December 31, 1998, the Company on an unconsolidated basis had $5 million
in cash and due from banks and $15 million in short-term securities purchased
under agreement to resell, compared with $6 million and $4 million,
respectively, at December 31, 1997. The increase in excess funds was primarily
due to the receipt of $24 million in dividends from subsidiaries during the year
partially reduced by dividends paid to shareholders of $17 million. In addition,
a $1 million capital contribution and $2 million demand loan was granted to one
subsidiary, Cambridge Trade Finance Corp. ("CTFC"). CTFC, a new company formed
during the year, is a Massachusetts-based trade finance corporation specializing
in serving small- to mid-sized importers and exporters throughout New England.

Deposits

The following table sets forth the remaining maturities of certificates of
deposit in the amount of $100 thousand or more at December 31, 1998:

Short-term Borrowings

The Company's short-term borrowings consist primarily of federal funds
purchased, securities sold under agreements to repurchase and FHLB borrowings.
These instruments generally range from overnight to one month in duration.

interest rate risk

Volatility in interest rates requires the Company to manage interest rate risk
that arises from differences in the timing of repricing of assets and the
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 23 percent of total assets. The Company has historically managed
its interest rate GAP primarily by lengthening or shortening the maturity
structure of its securities portfolio.

     The Company's GAP presentation may not reflect the degree 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 either the prime rate, the London Interbank Offered Rate ("LIBOR") or
treasury bill index.

     The following table summarizes the Company's GAP position at December 31,
1998. 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 as 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 December 31, 1998, the one-year cumulative GAP position was
negative at $223 million, or approximately 4 percent of total assets.

     During 1998, the average life of earning assets was extended through
reductions in federal funds sold and replacement and build-up in the securities
portfolio of longer-term securities containing reduced economic risk from
prepayment. In addition, the average life of interest-bearing liabilities was
shortened as long-term borrowings were replaced at maturity with short-term or
overnight borrowings. This positioning has allowed the Company to take advantage
of the falling interest rate environment that has resulted in lower funding
costs while maintaining yield on earning assets.

     The Company also uses simulation analysis to measure the exposure of net
interest income to changes in interest rates over a relatively short (i.e., 12
month) time horizon. Simulation analysis involves projecting future interest
income and expense from the Company's assets, liabilities, and off-balance sheet
positions under various scenarios. The Company's limits on interest rate risk
specify that, if interest rates were to shift immediately up or down 200 basis
points, estimated net interest income for the next 12 months should decline by
less than 10 percent. The following table reflects the Company's estimated
exposure as a percentage of estimated net interest income, and consequently net
income, for the next 12 months, assuming the indicated immediate shifts in
interest rates:

- -----------------------------------------------------------------------------------------------
</TABLE>

     As shown in the table above, the effect of a large fluctuation downward of
200 basis points, given the Company's liability-sensitive balance sheet
position, would produce a minimal 0.4 percent decrease in net interest income
over the next 12 months. A market rate shift upward would reduce net interest
income by 3.4 percent over the next 12 months. A restated estimated exposure as
of December 31, 1997 for acquisitions accounted for as poolings of interests is
not included in the table above as such information is not readily determinable.

     Shortcomings are inherent in any simulation analysis. Certain assets, such
as adjustable rate loans, have features which restrict changes in interest
rates. Additionally, the proportion of fixed-rate loans in the Company's
portfolio could increase in future periods if market interest rates remain at or
decrease below current levels due to refinance activity. Further, in the event
of a change in interest rates, early withdrawal and prepayment levels could
deviate significantly from those assumed in the analysis. Finally, the ability
of some borrowers to repay their adjustable rate loans may decrease in the event
of interest rate increases.

     On January 31, 1997, the Securities and Exchange Commission issued final
rules governing disclosure requirements for financial instruments, including
derivatives. This new release requires more detailed disclosure than required in
SFAS No. 119, "Disclosures about Derivative Financial Instruments and Fair Value
of Financial Instruments." However, the additional disclosures are only required
when material. As of December 31, 1998 and 1997, the positive fair value of
derivatives outstanding was immaterial to the Company's financial statements as
a whole and, therefore, these additional disclosures are not presented.

capital

There are three capital requirements that banks and bank holding companies must
meet. Two requirements take into consideration risks inherent in assets for both
on- and off-balance sheet items on a risk-weighted basis ("risk-based assets").
Risk weightings are as determined by banking regulators for the industry. Under
these requirements, the Company must meet minimum Tier 1 and Total risk-based
capital ratios (capital, as defined in the regulations, divided by risk-based
assets) of 4 percent and 8 percent, respectively. Tier 1 capital is essentially
shareholders' investment, net of intangible assets and Tier 2 capital is the
allowable portion of the loan loss reserve (as defined) and discounted
subordinated debt. Total capital is the combination of Tier 1 and Tier 2. The
third requirement is a leverage capital ratio, defined as Tier 1 capital divided
by total average assets, net of intangibles. All but the most highly-rated banks
are required to maintain a minimum of 4 percent. The Company has not been
notified of a specific requirement above the minimum. All three capital ratios
are calculated excluding the effect of unrealized gain/loss on securities
available-for-sale. Management believes, as of December 31, 1998, that the
Company and its subsidiary banks meet all of their respective capital adequacy
requirements. Refer to Note 17 to the Notes to Consolidated Financial Statements
of this Form 10-K for a further discussion of capital requirements.

     In 1998, the Company declared quarterly cash dividends totaling $23
million, or $0.54 per share, to stockholders. Also, during the year the
Company's subsidiaries declared dividends payable to the Company totaling $37
million, $2 million from USTC and $35 million from USTrust and second tier bank
holding companies of the Company.

     In 1995, the Company adopted a shareholder rights plan and in 1998 the
Company's Board of Directors approved a stock repurchase program. Refer to Note
17 to the Notes to Consolidated Financial Statements for a discussion.

credit quality and reserve for possible loan losses

Credit quality of the commercial loan and lease portfolios is quantified by a
corporate credit rating system designed to parallel regulatory criteria and
categories of loan risk. Individual lenders monitor their loans to ensure
appropriate rating assignments are made on a timely basis. Risk ratings and
quality of both commercial and consumer credit portfolios are also assessed on a
regular basis by an independent Loan Review Department which reports to the
Company's Board of Directors through its Asset Quality Committee. Loan Review
personnel conduct ongoing portfolio trend analyses and individual credit reviews
to evaluate loan risk and compliance with corporate lending policies. Results
and recommendations from this process provide senior management and the Board of
Directors and its Asset Quality Committee with independent information on loan
portfolio condition. The Asset Quality Committee monitors asset quality
throughout the year and actively reviews the large credit exposures. Consumer
loan quality is evaluated on the basis of delinquent data due to the large
number of such loans and relatively small size of individual credits. Historical
trend analysis reports are reviewed on a monthly basis by senior lending
officers and the Company's Board of Directors.

     At December 31, 1998, substandard loans totaled $50 million, compared with
$53 million at year-end 1997. 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 loans on nonaccrual, 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.

     At December 31, 1998, Substandard and Doubtful loans were $48 million and
$2 million, respectively. Substandard loans include $35 million of accruing
commercial and commercial real estate loans, of which 91 percent were current
with respect to contractual principal and interest payments, and $13 million in
loans that were on nonaccrual and included in nonperforming assets. All of the
loans rated Doubtful were on nonaccrual and included in nonperforming assets.
Also, at December 31, 1998, loans rated Special Mention in the Company's
internal risk rating profile amounted to $34 million, all of which were current.
Special Mention loans, as defined by the Company, have potential weaknesses that
deserve management's close attention. If left uncorrected, these potential
weaknesses may result in deterioration of the repayment prospects for the
assets.

     As of year-end 1998, approximately 63 percent of loans classified as
Substandard or Doubtful were collateralized by real estate, and the remainder
were collateralized by accounts receivable, inventory, equipment and other
business assets. Of the loans secured by real estate, approximately 38 percent
were collateralized by owner-occupied commercial properties, approximately 56
percent were collateralized by other commercial real estate, and approximately 2
percent by residential real estate. The remaining loans were collateralized by
real estate under construction or raw land.

     The upcoming Year 2000 event has prompted the Company to establish a
comprehensive process of customer interaction designed to provide information on
borrower readiness for the Year 2000. It is the Company's position that the Year
2000 business problem presents an additional credit consideration. Accordingly,
the evaluation program parallels existing credit practices. An additional
rating, "the Millennium Rating," has been established to assess the Year 2000
readiness of each credit and to identify loans which represent Year 2000 risk.
Any loans which have been determined to have "Millennium Special Mention" or
"Millennium Substandard" ratings will be reviewed and a determination will be
made if any remedial action is necessary. In some cases, an addition to the
reserve for possible loan losses may be necessary. For a further discussion of
the Year 2000 issue, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

     As exhibited in the preceding table, total nonperforming assets were
reduced $27 million in 1998 to $31 million. The decrease was led by a $17
million reduction in restructured loans and a reduction in nonaccrual commercial
loans and residential mortgage loans. These reductions were due in part to the
sale of $21 million in substandard commercial and residential loans during the
third quarter of 1998. The indirect automobile loan increase from 1997 reflected
the substantial increase in balances outstanding of these loans. The reserve to
total nonaccrual loans, accruing loans 90 days or more past due and restructured
loans improved to 246.0 percent at December 31, 1998, compared with 132.8
percent a year ago. Reserve to total loans decreased to 1.5 percent from 1.7
percent a year ago.

     The Company's consumer loan delinquency rates (greater than 30 days past
due including nonaccruals) continue to remain at favorable levels. The
delinquency rate for the indirect automobile loans, the second largest component
of the Company's consumer loan portfolio was 3.03 percent at December 31, 1998,
compared with 3.20 percent at December 31, 1997. The Company anticipates that
the current high growth rate experienced in the indirect automobile loan
portfolio will subside in future periods. This factor, combined with the
eventual maturity of the existing portfolio, will likely result in an increase
in the delinquency rate in future periods.

     At December 31, 1998, total impaired loans were $13.4 million, comprised of
$.6 million that required a reserve for possible loan losses of $.3 million, and
$12.8 million that did not require a related reserve. The Company has defined
impaired loans as commercial and commercial real estate loans recognized by the
Company as nonaccrual and restructured. Refer to Notes 1 and 6 to the Notes to
Consolidated Financial Statements of this Form 10-K for a further discussion on
SFAS No. 114. The amount of interest on December 31, 1998 impaired loans that
would have been recorded had the loans been paying in accordance with their
original terms during 1998 was approximately $2.6 million. The amount of
interest income on these loans included in net income in 1998 was approximately
$1.2 million.

Reserve for Possible Loan Losses

     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. Factors 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. The analysis 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 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 and ratio of
loans in each category to total loans at December 31, 1994 through 1998 is
presented below:

     The reserve for possible loan losses was $65.3 million at December 31,
1998, down $3.3 million from a year ago. Net chargeoffs of $5.5 million were
partially offset by a $2.2 million provision for possible loan losses during the
year. Reserve allocated to commercial and financial loans increased from 1997
due to volume growth in these loans and reserve allocated to consumer loan
increased due to growth in the indirect automobile portfolio. The unallocated
portion of the reserve at year end was $3.1 million, or 5 percent of the
reserve, down from $8.9 million, or 13 percent, of the reserve a year ago. The
decrease in the unallocated portion is a direct result of the improving asset
quality trend. The ratio of nonperforming assets to total assets has continued
to decline from 2.2 percent in 1995 to 1.5 percent in 1996, 1.1 percent in 1997
and 0.5 percent in 1998. This improvement in asset quality, allowed the Company
to reduce the level of unallocated reserves maintained during this time frame.
The Company expects to continue to maintain reserve levels that are consistent
with asset quality and the risk inherent within the loan portfolios.

through 1998 is presented below:

                              results of operations

comparison of 1998 with 1997

For the year ended December 31, 1998, net income was $55.3 million, or $1.28
diluted earnings per share, compared with $50.2 million, or $1.18 diluted
earnings per share, for the year ended December 31, 1997. Operating results
included charges of $8.1 million and $4.4 million in 1998 and 1997,
respectively, for certain nondeductible merger-related expenses and pre-tax
charges of $11.5 million and $11.8 million in 1998 and 1997, respectively, for
restructuring charges related to acquisitions. The 1998 charges were recorded in
connection with the Somerset and Affiliated acquisitions while the 1997 charges
were incurred primarily for the Walden acquisition. Excluding merger-related and
restructuring charges, 1998 net income was $70.5 million, or $1.63 diluted
earnings per share, compared with $61.7 million, or $1.44 diluted earnings per
share last year.

     Net income for 1998, including the aforementioned merger-related and
restructuring charges, produced a return on average stockholders' investment of
10.69 percent compared with 11.13 percent in 1997, and a return on average
assets of 0.99 percent compared with 0.95 percent last year. Operating return on
average equity (excluding merger-related and restructuring charges) was 13.63
percent, just below the 13.66 percent earned in 1997. The positive effect of
this year's earnings increase on this performance ratio was offset by the effect
of a $66 million increase in average equity from earnings retained during the
year. Operating return on average assets was 1.26 percent this year compared
with 1.17 percent last year.

Net Interest Income Analysis

The Company's net interest income on a fully taxable equivalent basis was $253.5
million in 1998, an increase of 9 percent, or $21.6 million over 1997. The
increase over last year was due to a combination of earning asset growth,
favorable changes in earning asset and deposit mix, noninterest-bearing and
low-cost deposit growth and lower borrowing costs. The table below presents the
following information: average earning assets and average interest-bearing
liabilities supporting earning assets; and interest income and interest expense
expressed as a percentage of the related asset or liability. The average
balances and the rates presented include the effect of fair value adjustments
under SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
Securities."

(1)  Interest on loans to and obligations of states and political subdivisions
     is not subject to federal income tax and certain dividend income from
     equity securities receive preferential tax treatment. In order to make
     pretax yields comparable to fully taxable loans and securities, a tax
     equivalent adjustment is utilized. The adjustment is based on a 35 percent
     federal income tax rate and includes applicable state taxes, net of federal
     tax benefit.

(2)  Average loan balance includes nonaccrual loans, such that the negative
     income effect is included in the calculation of average rates.

(3)  Net interest spread is the excess of the interest rate on average earning
     assets over the interest rate on average interest-bearing liabilities.

(4)  Net interest margin is the excess of the interest earned over interest
     expense divided by average earning assets.

     As reflected in the foregoing table, average loans increased 10 percent, or
$372 million to $4.091 billion this year. As exhibited in the table below, loan
growth was the largest contributor to the improvement in net interest income
over 1997. Lower-yielding average assets, such as securities decreased $32
million and Federal funds sold decreased $30 million. Average low-cost savings
deposits, including regular savings, NOW and money market, increased 6 percent,
or $109 million from 1997, while average high-cost certificates of deposit
decreased $69 million. The positive differential between average total earning
assets and average total interest-bearing liabilities increased $216 million
from 1997 due to an increase in noninterest-bearing deposits as well as retained
earnings and contributed to the increase in net interest income. The increases
in average low-cost and noninterest-bearing deposits reflects the Company's
success at attracting these deposits with its very competitive deposit account
fee structure. The effect on net interest income from these favorable changes in
volume of interest-earning assets and interest-bearing and noninterest-bearing
liabilities was an increase of $26.4 million for the year ended December 31,
1998 compared with 1997.

     Yield on earning assets declined 11 basis points to 8.09 percent in 1998. A
decrease in yield on loans of 20 basis points from 1997 was the largest factor
affecting total earning asset yield. Loan yields, in particular rates on new
commercial loans, continue to reflect the effect of competitive pressure on loan
pricing. The Company expects that such competitive pressure will continue into
next year. In general, market interest rates were on a downward trend during
1998. During the latter half of 1998, the Federal Reserve Board announced
interest rate cuts in the rate charged to member banks for borrowings from the
Federal Reserve. As a result, the Company's subsidiary banks, consistent with
most banks across the country, decreased the prime lending rate a total of 75
basis points. Such rate decreases are expected to continue to reduce yield on
earning assets in future periods. The cost of interest-bearing liabilities
decreased 14 basis points this year to 4.15 percent. Rates on the low-cost
deposits, NOW, money market and regular savings were maintained or increased
from 1997 as part of a strategy to promote growth in this deposit category. The
average cost of time certificates of deposit decreased 10 basis points compared
to a year ago, as older certificates matured and repriced at the current lower
offering rates. The Company expects to continue to adjust rates on new
certificates as well as some savings products consistent with the general trend
in interest rates. Borrowing costs decreased 36 basis points compared with a
year ago due to the replacement of long-term, higher rate borrowings with
short-term or overnight borrowings. This is expected to continue to allow the
Company to take advantage of falling interest rates and thereby reduce funding
costs. The net effect of rate changes on net interest income for the year ended
December 31, 1998 compared with the same period in 1997, was a decrease of $4.8
million.

     As a result of the aforementioned yield, cost and volume changes, the
interest rate margin and spread increased slightly from 4.64 percent and 3.91
percent in 1997 to 4.77 percent and 3.94 percent in 1998, respectively. The
Company expects to maintain the current level of net interest margin and spread
through the next year. The combination of the Company's balance sheet
positioning and ability to adjust certain funding costs are expected to aid in
this effort. Although such expectations, which are subject to the volatility of
market interest rates, may not be realized. Refer to the caption "Interest Rate
Risk" in this Form 10-K for a further discussion of balance sheet positioning.

     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 year ended
December 31, 1998 when compared with the year ended December 31, 1997. Changes
attributable to both rate and volume are allocated on a weighted basis.

*    Fully taxable equivalent at the federal income tax rate of 35 percent and
     includes applicable state taxes net of federal benefit. The tax equivalent
     adjustment on loans was approximately $.2 million and on nontaxable and
     preferential rate income securities was approximately $1.0 million.
- --------------------------------------------------------------------------------

Noninterest Income

Total noninterest income was $48.8 million, $7.1 million higher than 1997.
Realized net gains on sales of securities, including $2.1 million in realized
gains on venture capital investments, were $3.9 million this year compared with
realized net losses of $1.2 million in 1997. The Company's three key fee-based
businesses showed strong improvement over 1997. Asset management fees increased
$2.1 million, or 16 percent, due to growth in balances under management from new
business and favorable market results. Assets under management increased $380
million during the year to $3.5 billion. Deposit account service charges
increased $1.2 million, or 11 percent, due to increased revenue from NSF charges
and growth in demand deposit and nontime savings deposits. Corporate services
income rose $.5 million, or 8 percent, due to growth in commercial cash
management services. Gains from loan sales this year were $.7 million, which
includes gains on sale of fixed rate residential mortgage loans in the secondary
market and gain on sale of substandard loans. Gains on sale of loans in 1997
were mostly from the sale of substandard loans.

Noninterest Expense

Total noninterest expense was $209.2 million, an increase of $19.0 million over
1997. Restructuring charges of $11.5 million were incurred in 1998 in connection
with the Somerset and Affiliated acquisitions and the result of management's
integration plan. These costs related to activities that had no future economic
benefit to the Company and were incremental to other costs incurred in the
conduct of the Company's business. The nature of these expenses included charges
for severance payments to former Somerset and Affiliated executives and staff,
processing systems conversions and deconversion costs, customer communications
related to the effect of the acquisitions and new account information,
write-offs of certain assets such as signage and incompatable computer
equipment, and other expenses directly associated with the integration of the
acquired institutions. Similar restructuring charges of $11.8 million for the
year ended December 31, 1997 were incurred in connection with the Walden
acquisition.

     Acquisition and merger-related expenses, a nondeductible expense for tax
purposes, of $8.1 million, were incurred in 1998 in connection with the Somerset
and Affiliated acquisitions. These expenses included professional, legal,
accounting and investment banking services directly incurred in connection with
the acquisition transactions. Acquisition and merger-related expense of $4.4
million was incurred in 1997 primarily in connection with Walden and Firestone
acquisitions.

     The increase in total noninterest expense in 1998 also reflects Year 2000
readiness expense of $5.4 million compared to a nominal expense in 1997. Also
higher were personnel costs of $6.6 million, computer equipment depreciation and


                                       26
<PAGE>   27

maintenance costs of $1.8 million, and increased data processing costs of $1.9
million. These operating expense increases are primarily the result of volume
growth across the Company. In addition, the merger with and into USTrust and
integration and conversion of the operating systems of the acquired banks, did
not occur until late in the year. As a result, the Company's noninterest expense
does not reflect the full cost savings and efficiencies associated with the
acquisitions. The Company expects additional operating efficiencies related to
acquisitions to be realized in the first half of 1999.

     Other noninterest expense approximated last year's level of $27 million.
Communication expenses such as postage, telephone, and stationery and supplies,
which aggregate approximately $11 million in 1998, are the largest components.
Also included in other noninterest expense in 1998 were $2.7 million in one-time
costs in connection with the upgrade of the Company's automated branch platform
and teller systems and a writedown to net realizable value of a branch building
held for sale. These increases were offset with lower legal reserve provisions
and checkbook charges than 1997.

     The operating efficiency ratio, which excludes realized gains/losses on
sales of securities and loans, merger-related and restructuring expenses and
foreclosed asset expense, was 62.8 percent in 1998 compared with 63.3 percent in
1997. Excluding Year 2000 readiness expense, the 1998 ratio would further
improve to 61.0 percent. The Company expects to focus on operating efficiencies
in 1999 in an effort to further improve efficiency ratios.

Year 2000

The Year 2000 issue, which is common to most corporations, concerns the
potential inability of computer-based systems, including among others, computer
hardware, embedded chips, and computer software programs, to recognize properly
and process date-sensitive information involving 20th and 21st century dates.

State of Readiness

In 1997, the Company assembled a project team of senior officers and outside
consultants to assess the impact of the Year 2000 problem on its systems and
certain systems of its customers, vendors and other parties that service or
otherwise interact with the Company and to develop a Year 2000 Readiness Program
consistent with the five phases set out in Regulatory Guidance. A national
public accounting firm was engaged by the Company to focus on assisting in
initial project development and progress assessment. The Company's Year 2000
Readiness Program contains a number of discrete segments, including among
others, Awareness, Assessment, Project Planning, Remediation, Unit Test
Plans, Unit Testing, Integration Testing, System Implementation, Commercial
(including evaluation and monitoring stages), Funds Providers and Capital
Markets, Retail, Contingency Plans for Information Systems and Contingency Plans
for Business Continuation.

     The Awareness and Assessment phases, Project Planning for all aspects and
Unit Test Plans for mission critical systems have been completed. Mission
critical systems are defined by the Company as those vital to the successful
continuance of core business activities. Test Plans for noncritical applications
are in process of development and are expected to be substantially completed
during the second quarter of 1999. Inventory and Year 2000 readiness assessment
of all information and noninformation systems and applications have been
completed and all third-party vendors who provide applications to the Company
have been contacted. Efforts to bring the major operating systems, and certain
outsourced applications into compliance with Year 2000 requirements have or will
be accomplished primarily through the installation of updated or replacement
programs developed by third parties. In addition, the status of all Company
facilities and all significant third-party providers of goods and services to
the Company has been assessed. Starting in March 1998, the Company retained the
services of Atlantic Data Services, Inc., and certain additional outside
advisors and programmers to augment the Company's efforts in addressing its Year
2000 compliance.

     The Remediation Phase, wherein software and hardware are either modified or
replaced, was substantially completed by year-end 1998 for mission critical
applications. The Company successfully installed among other mission critical
applications systems, a new commercial loan system and upgraded versions of its
transaction deposit, certificate of deposit, ACH, wire transfer, general ledger
and mortage processing systems. In addition, the Company has upgraded or
replaced all of its mission critical mainframe operating systems that were not
Year 2000 compliant and upgraded its broadly distributed PC network, operating,
and office systems. One exception was the branch teller system, which the
Company discovered through its Unit Testing procedures did not properly process
the leap year date February 29, 2000. The Company expects to receive a new
version before the end of April 1999. The second exception is the Company is
awaiting the remediation and test results of the systems utilized by a
third-party vendor that provides mutual fund and annuity broker and dealer
services to the Company. The Year 2000 readiness results are expected from this
service provider by March 31, 1999. The Remediation phase for nonmission
critical applications is presently scheduled to be completed by September 30,
1999.

     Unit Testing of individual mission critical systems was substantially
completed by December 31, 1998. Unit Testing for nonmission critical systems is
expected to be substantially complete by the end of the first half of 1999.


                                       27
<PAGE>   28

To help achieve the completion of testing for nonmission critical applications,
the Company has engaged the services of an additional third-party vendor,
Command Systems, Inc. The targeted completion date for Integrating Testing for
mission critical systems is March 31, 1999, and for nonmission critical systems
the end of the third quarter of 1999. Integration testing involves the testing
of applications on an integrated basis with systems interacting or exchanging
data in a future date environment.

     As part of the System Implementation phase, the Company has generally put
mission critical applications into production as soon as remediation or
replacement installation was completed. As of year-end 1998, the process of
system implementation was substantially complete with all but three of the
remediated systems placed into production. These three, ATM, installment loan
and installment loan origination, are scheduled to be installed by June 30,
1999.

     The Company has put in place a substantial program for evaluating potential
additional credit risk that might arise should any of its large commercial
customers experience their own Year 2000 issues. The initial portion of the
Commercial Phase, which included the evaluation of credit risk stemming from
problems borrowers may have in resolving their own Year 2000 issues, has been
completed. Monitoring of the remediation efforts of high risk customers will be
ongoing. During the monitoring stage the Company has implemented a course of
action and procedures designed to reduce any increased potential credit risk as
a result of borrowers' Year 2000 issues. The Company is communicating with its
major borrowing relationships on a quarterly basis and evaluating credit risk
related to Year 2000 issues based on responses from these customers. Risk
mitigation plans will be developed during 1999 for those customers whose Year
2000 credit risk component remains high. Such plans will utilize the normal
process that the Company employs to manage credit risk.

     The Company continues an active program of evaluation, assessment and
monitoring of the state of readiness of the Company's Funds Providers and the
Capital Markets. This program has been expanded to include development of
alternative sources of funds should the Company require them over year-end 1999.
However, there are no funds providers that, on an individual basis or in the
aggregate, are material to the Company except for the Federal Home Loan Bank
("FHLB") of Boston. The FHLB continues to communicate with the Company and
report on their state of Year 2000 readiness, which currently is on track with
its management's schedule. The Company has put in place contingency plans for
additional funding through large brokered certificates of deposit from
investment houses as well as made arrangements to increase the Company's
availability of fund borrowings from the Federal Reserve Bank of Boston.

     The Retail segment is largely focused on customer communications as to the
state of the Company's Year 2000 readiness and ensuring adequate cash
availability is maintained over year-end 1999. The initial communications have
been distributed and the process is ongoing. Customer and community
communications will receive greater emphasis during 1999. This will include
personal communication with selected large customers, training for internal
staff, placement of FDIC brochures in the banking branches, a regular Year 2000
update on the Company's web site and frequent written communication with
customers by use of statement inserts or other means.

Risks of Year 2000 Issues

The Company has yet to identify any application or operating system or
third-party support which appears unlikely to be Year 2000 compliant or for
which a suitable alternative cannot be implemented. Since, however, the Company
is heavily dependent on such software and third parties, there are risks that
the Company's operations could be disrupted by adverse developments affecting
the operations of these third parties. Such risks include, among other matters,
an inability to process and underwrite loan applications, to credit deposits and
withdrawals from deposit accounts, to credit loan payments or track
delinquencies, to properly reconcile and record daily activity or to engage in
normal banking activities, including branch and ATM operations. A failure in any
one of these could have a material effect on the Company. Additionally,
commercial borrowers whose operations depend on automated systems could
experience Year 2000 compliance problems affecting their ability to repay. It is
not possible to quantify the magnitude of any potential increased credit risk at
this time. It is, therefore, possible that the Company's financial condition and
results of operations could be adversely affected by increases in problem loans
and credit losses in future periods and require the Company to record additional
loan loss provisions. The Company also faces financial risk from its fund
providers as the Year 2000 problem may produce some deposit contraction forcing
a change to alternative and higher cost funding sources. Finally, to the extent
that certain utility and communication services utilized by the Company face
Year 2000 problems, the Company's operations could be disrupted.

     Ultimately, an estimation of the efforts of the Company in addressing the
Year 2000 issue in a successful and timely manner depends to a large extent not
only on the corrective measures that it undertakes, but also on the efforts
undertaken by businesses and other independent entities who provide data to, or
receive data from, the Company as borrowers,


                                       28
<PAGE>   29

vendors or customers. If the Company's Year 2000 Readiness Program were
unsuccessful, it would have a material adverse effect on its future operating
results and the financial condition. Accordingly, the Company's Board of
Directors is actively involved in monitoring management's efforts to address
Year 2000 readiness and has instructed management to allocate appropriate
resources to address these matters.

     Bank regulatory agencies have issued guidance as to the standards they will
use when assessing Year 2000 readiness. The failure of a financial institution,
such as the Company, to take appropriate steps to address deficiencies in their
Year 2000 project management process could result in regulatory enforcement
actions which could have a material adverse effect on the institution, result in
the imposition of civil money penalties, or result in the delay (or receipt of
an unfavorable or critical evaluation of management of a financial institution
in connection with regulatory review) of applications seeking to acquire other
entities or otherwise expand the institution's activities.

     The most serious impact on the Company's operations, however, would result
if basic services such as telecommunications, electric power, and services
provided by other financial institutions and governmental agencies were
disrupted. Some public disclosure about readiness preparation among basic
infrastructure and other suppliers is now available; however, the Company is
unable at this time to estimate the likelihood of significant disruptions among
our basic infrastructure suppliers. In view of the unknown probability of
occurrence and impact on operations, the Company considers the loss of basic
infrastructure services to be the most reasonably likely worst case Year 2000
scenario.

Costs to Address the Year 2000 Issue

The Company has made resolution of Year 2000 issues a top priority, and has
committed substantial financial, technical and management resources to the
project.

     The Company believes that it will be able to modify or replace any affected
systems in time to minimize any detrimental effects on its operations. The
Company expects that it will incur costs to replace existing hardware and
software which will be capitalized and amortized in accordance with the
Company's existing accounting policy while maintenance or modification costs
will be expensed as incurred. At December 31, 1998, Year 2000 external readiness
expense totaled $5.5 million, nearly all of which was recorded during 1998.
Although total external costs for the entire project have yet to be determined,
the Company expects to incur, as current operating expense (including the above
$5.5 million), costs in the range of $9 to $10 million to assure Year 2000
readiness. This estimate represents an increase over the September 30, 1998
estimate of $7 to $8 million and results primarily from additional third-party
costs to be incurred in the testing phase. These costs and estimates do not
include internal costs incurred for Year 2000 matters. Such internal costs,
which are not separately tracked by the Company, consist principally of payroll
costs of its information systems group. Capital expenditures for new equipment
and software purchases are expected to total an additional $1 million. This
estimate does not include the cost of a number of system installations
previously planned by the Company in the normal course of business. Costs of the
Year 2000 project are based on current estimates and actual results could vary
significantly from such estimates. As a result of the focus on the Year 2000
Readiness Program, the Company has deferred some proposed systems projects but
none that has had or is likely to have a material adverse impact on its
operations.

Contingency Plans

The Company has three types of contingency plans: Remediation, Business
Continuation and Event Management. Remediation Contingency Plans address the
failure to complete remediation of an internal Mission Critical application or
failure of a third-party service provider to complete remediation of a Mission
Critical application. Remediation Contingency Plans for all mission critical
technology systems were completed in 1998. As a result of substantial completion
of the Remediation, Unit Testing and System Implementation segments on mission
critical systems, the number of systems still on the remediation contingency
list is minimal. Business Continuation Plans are based largely on existing
Disaster Recovery Plans, but include additional planning and materials that
address those conditions that are unique to Year 2000. Lastly, the Company is
working on an Event Management Plan that addresses how the Company will manage
risks prior to year end; how it will respond to any infrastructure failures
should they occur during the century change over, and how the Company will
communicate with customers on the status of operations during the end of 1999
through the beginning of 2000. Business Continuation Plans and the basic Event
Management Plan are expected to be completed by June 30, 1999.

Income Taxes

The Company recorded income taxes of $34.4 million compared with $28.6 million
in 1997 due mostly to the higher level of pre-tax income this year. The
effective tax rate for 1998 was 38.3 percent compared with 36.3 percent last
year.


                                       29
<PAGE>   30

The effective tax rate in 1998 and 1997 was influenced by $8.1 million and $4.4
million, respectively, in nondeductible acquisition and merger-related expenses.
Excluding such charges, the effective tax rates were 35.2 percent and 34.4
percent, respectively, in 1998 and 1997. This year's effective rate was higher
than 1997 due to utilization of certain net operating loss carryforwards at one
of the acquired institutions last year. Refer to Note 15 to the Notes to
Consolidated Financial Statements of this Form 10-K for a further discussion of
income taxes.

     As of December 31, 1998, other assets included deferred tax assets of
approximately $18.5 million, which are expected to be realized against future
taxable income. Management believes that it is more likely than not that the
Company will realize the benefit of these deferred assets.

Fair Value of Financial Instruments

The methods and assumptions used to estimate the fair value of each class of
financial instruments as of December 31, 1998 and 1997, in accordance with SFAS
No. 107, "Disclosures about Fair Value of Financial Instruments," are discussed
in Note 22 to the Notes to Consolidated Financial Statements of this Form 10-K.
Financial Instruments do not include all of the assets and liabilities recorded
on a company's balance sheet. Therefore, the aggregate fair value amounts of the
Financial Instruments do not represent the underlying value of a company.

     As a result of those assumptions and valuation methodologies, the estimated
fair value of Financial Instrument assets as of December 31, 1998 and 1997 was
$5.55 billion and $5.28 billion, respectively, or $62 million and $57 million,
respectively, in excess of carrying value. The increase in excess of fair value
over the carrying value of Financial Instrument assets of $5 million is
primarily attributed, in the opinion of management, to lower market interest
rates for loans at year-end 1998. The estimated fair value of Financial
Instrument liabilities as of December 31, 1998 and 1997 was $5.31 billion and
$4.99 billion, respectively, or $11 million and $3 million, respectively, higher
than carrying value. The net increase in fair value of Financial Instrument
liabilities was primarily due to lower rates on certificates of deposit at
year-end 1998 compared with year-end 1997.

comparison of 1997 with 1996

Net Interest Income Analysis

The Company's net interest income on a fully taxable equivalent basis was $231.9
million in 1997, $39.7 million higher than 1996. The increase in net interest
income was due to the additional volume of interest-earning assets and
interest-bearing liabilities assumed in the fourth quarter 1996 acquisition of
twenty banking branches from Bank of Boston Corporation ("Branch Purchase"), and
improvements in earning asset mix and volumes. Market rates were relatively
level during 1997 and not a major factor in the interest margin growth over
1996.

     Yield on loans in 1997 was 8.81 percent, down slightly from 8.86 percent a
year earlier, due mostly to external pressure on loan pricing of new loans,
particularly commercial credits. Yield on securities improved from 6.22 percent
to 6.47 percent reflecting the positive impact of a restructuring program under
which lower-yielding securities with higher risk of prepayment were sold during
1997. Yield on earning assets increased 16 basis points from 8.04 percent in
1996 to 8.20 percent in 1997 due to a shift in earning asset mix from securities
to higher yielding loan assets, and from the securities yield improvement. The
cost of interest-bearing liabilities decreased 12 basis points to 4.29 percent.
Deposit costs, the principal component of interest expense, crept downward
during the year from 3.51 percent to 3.35 percent. The rollover of certificates
of deposit at the current lower rates was the largest contributor to the cost of
funds decrease. The combined effect of a higher yield on earning assets with a
lower liabilities cost resulted in improvement in interest margin and spread
from 4.33 percent and 3.63 percent, respectively, in 1996, to 4.64 percent and
3.91 percent, respectively, in 1997.

*    Fully taxable equivalent at the federal income tax rate of 35 percent and
     includes applicable state taxes net of federal benefit. The tax equivalent
     adjustment on loans was approximately $.4 million and on nontaxable and
     preferential rate income securities was approximately $1.0 million.
- --------------------------------------------------------------------------------

     Average earning assets for 1997 were $5.002 billion, $575 million higher
than 1996. Average securities volume decreased $114 million to $1.194 billion
due to the aforementioned portfolio restructuring. Average loan volume increased
21 percent, or $652 million, to $3.718 billion in 1997. The increase in loan
volume reflects the full year average of the loans acquired in the late 1996
Branch Purchase and loan growth during 1997. As noted in the table above, total
interest income increased $52.5 million due to changes in earning asset volume.
Average interest-bearing deposits increased $447 million to $3.328 billion due
to the full year average of deposits acquired in the Branch Purchase and deposit
growth during the year. When combined with a $9 million decrease in average
borrowings, changes in volume of interest-bearing liabilities resulted in an
increase of $14.0 million interest expense over 1996. The net positive
differential between average total earning assets and average total
interest-bearing liabilities increased $137 million in 1997 which also
contributed to the favorable volume-related variance.

Noninterest Income

Total noninterest income was $41.7 million, $1.0 million lower than 1996.
Included in 1997 was $1.2 million in realized securities losses compared with
$1.1 million in realized securities gains in 1996. The 1997 securities losses
reflect the aforementioned portfolio restructuring. Deposit account service
charges increased 35 percent, or $2.8 million, from 1996 to $10.9 million.
Corporate services income, which includes merchant credit card income net of
card processing expense, increased 27 percent, or $1.2 million, to $5.7 million.
The increase in both deposit and corporate fee income reflects the additional
volume of accounts obtained in the December 1996 Branch Purchase and new account
growth in 1997. The 1997 realized gain on the loans held-for-sale portfolio was
$2.2 million compared with a nominal gain in 1996. Other noninterest income
increased $2.0 million from 1996 due primarily to increased Debit Card income, a
new product introduced in late 1996, and the benefit of the larger branch
network and resulting increase in ATM fee income from noncustomer users. Asset
management fees, the largest component of noninterest income, remained
consistent with 1996 at $13.0 million.

<PAGE>   32

Noninterest Expense

Total noninterest expense was $190.2 million in 1997, an increase of $30.6
million over 1996. The largest component of the increase resulted from charges
related to acquisitions. 1997 included an $11.8 million restructuring charge
consisting of expenses for severance payments to former Walden executives and
staff, write-offs of certain Walden assets and contract buyouts, costs
associated with the conversion of Walden's systems to the Company's operating
systems, and certain other expenses associated with the integration of the
Walden banking subsidiaries. 1997 also included $4.4 million in acquisition and
merger-related expense primarily for professional services paid in connection
with the Walden and Firestone acquisitions. In 1996, acquisition and
merger-related expense was $5.9 million primarily related to the Branch
Purchase. Refer to Notes 2 and 14 of the Notes to Consolidated Financial
Statements for a further discussion of acquisitions.

     Salary and employee benefits, occupancy, equipment and furniture expense
increased a combined $15.5 million due mostly to the full year's operation and
support for the twenty banking branches acquired in December 1996. The $4.2
million increase in intangible asset amortization resulted from the premiums
paid in the purchase of the branches and associated assets. Data processing
services expense increased $2.7 million largely as a result of a higher use of
nonaffiliated banks' ATM's by new customers. The increase in advertising and
promotion is consistent with the Company's growth in assets and reflects the
many product promotions in 1997 and the advertising campaign, "THE other BIG
BANK." Deposit insurance premiums decreased from 1996, which included the $5.0
million one-time SAIF assessment. Refer to Note 14 to the Notes to Consolidated
Financial Statements for a further discussion of the one-time SAIF assessment.
Other noninterest expense increased $5.2 million reflecting higher costs
associated with operating an expanded branch network. Communications expenses,
including telephone, stationery and supplies, postage and delivery charges
accounted for most of the other noninterest expense increase.

cautionary statement regarding forward-looking information

The preceding discussion and Notes to Consolidated Financial Statements of this
Form 10-K contain certain forward-looking statements, including without
limitation the statements regarding (i) rates of loan growth and amortization;
(ii) expectations regarding future operating efficiencies; (iii) effects on net
interest margin from changes in market interest rates; (iv) the rate of
delinquencies and amounts of chargeoffs; (v) the level of reserve for possible
loan losses; (vi) the Company's ability to minimize any detrimental effects of
the Year 2000 issue, estimated completion dates of various phases of the Year
2000 Readiness Program, and estimated associated expense; (vii) utilization of
deferred tax assets; (viii) timing of completion of acquisitions; and (ix) the
purchase of a new operations center. 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 and estimates of
the effects of its acquisition activities. These forward-looking statements are
inherently uncertain and actual results may differ from Company expectations.
Risk factors that could impact current and future performance include but are
not limited to: (i) adverse changes in asset quality and the resulting credit
risk-related losses and expenses; (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 that can also negatively affect credit risk as 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) the consequences of continued bank acquisitions and mergers in the
Company's market, resulting in fewer but much larger and financially stronger
competitors which could increase competition for financial services to the
Company's detriment; (v) fluctuations in market rates and prices can negatively
affect net interest margin, asset valuations, asset management fees and expense
expectations; (vi) the various risk factors discussed under the caption "Risks
of Year 2000 Issues" of this Form 10-K; and (vii) changes in the regulatory
requirements of federal and state agencies applicable to bank holding companies
and banks, such as the Company and its Subsidiary Banks, which could have a
materially adverse effect on the Company's future operating results.

                    report of independent public accountants

To the Stockholders and Board of Directors of UST Corp.:

We have audited the accompanying consolidated balance sheets of UST Corp. and
subsidiaries (a Massachusetts corporation) as of December 31, 1998 and 1997, and
the related consolidated statements of income, changes in stockholders'
investment and cash flows for each of the three years in the period ended
December 31, 1998. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits. We did
not audit the financial statements of the Somerset Savings Bank as of December
31, 1997 and for each of the two years in the period ended December 31, 1997, a
bank acquired during 1998 in a transaction accounted for as a pooling of
interests, as discussed in Note 2 to the Notes to Consolidated Financial
Statements. Such statements are included in the consolidated financial
statements of UST Corp. and subsidiaries and reflect total assets of 9.8 percent
in 1997 and net interest income of 8.6 percent and 9.7 percent, respectively, in
1997 and 1996 of the related consolidated totals. These statements were audited
by other auditors whose report has been furnished to us and our opinion on the
consolidated financial statements of UST Corp. and subsidiaries for the years
ending December 31, 1997 and 1996, insofar as it relates to amounts included for
the Somerset Savings Bank, is based solely upon the report of the other
auditors.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements were
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits and
the report of other auditors provide a reasonable basis for our opinion.

     In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of UST Corp. and subsidiaries as of
December 31, 1998 and 1997, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1998, in
conformity with generally accepted accounting principles.

          notes to consolidated financial statements, december 31, 1998

note 1. nature of operations and summary of significant accounting policies

      UST Corp. is a bank holding company with two banking subsidiaries:
USTrust, the largest banking subsidiary, which represents 99 percent of the
Company's total assets, and United States Trust Company ("USTC"), each
headquartered in Boston, Massachusetts. UST Corp. and its banking and nonbanking
subsidiaries (the "Company") provide a broad range of financial services
principally to individuals and small- and medium-sized companies in the New
England region. Included in these services are commercial banking, retail
consumer financial services, trust and money management, and equipment leasing.
The Company, through its banking subsidiaries, presently operates 87 banking
branches and 117 automated teller and cash dispensing machines throughout
eastern Massachusetts.

      The accounting and reporting policies of the Company conform with
generally accepted accounting principles and general practice in the banking
industry. The preparation of financial statements in conformity with generally
accepted accounting principles requires the Company to make estimates and
assumptions that affect the reporting and disclosure of assets and liabilities,
including those that are of a contingent nature at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The
significant accounting and reporting policies of the Company are summarized
below.

Principles of Consolidation

      The consolidated financial statements include the accounts of UST Corp.
and its wholly-owned subsidiaries. All material intercompany balances and
transactions have been eliminated. The parent company only financial statements
contained in Note 21 reflect investments in subsidiaries using the equity method
of accounting.

      Certain reclassifications have been made to prior year balances to conform
with the current year presentation. All applicable prior-period amounts included
in these financial statements have been restated to reflect the January 3, 1997
acquisition of Walden Bancorp, Inc. ("Walden"), the October 15, 1997 acquisition
of Firestone Financial Corp. ("Firestone"), the July 20, 1998 acquisition of
Somerset Savings Bank ("Somerset"), and the August 7, 1998 acquisition of
Affiliated Community Bancorp, Inc. ("Affiliated") as poolings of interests.
Refer to Note 2 for a further discussion of acquisitions. Assets owned by others
and held in a fiduciary or agency capacity are not included in the consolidated
balance sheets.

Securities

The Company classifies investments in debt and equity securities in accordance
with Statement of Financial Accounting Standards No. 115 ("SFAS No. 115"),
"Accounting for Certain Investments in Debt and Equity Securities." This
Statement addresses the accounting and reporting for investments in equity
securities that have readily determinable fair values and for all investments in
debt securities. Under this statement such securities are classified as
held-to-maturity, trading, or available-for-sale.

      Securities Held-to-Maturity - Debt securities which management has the
positive intent and ability to hold to maturity are classified as
held-to-maturity, and are carried at cost adjusted for the amortization of
premium or the accretion of discount. Securities classified by the Company as
held-to-maturity were $260 million at December 31, 1997. All of the year-end
1997 held-to-maturity securities were owned by Somerset and Affiliated and were
redesignated as available-for-sale upon the closing of the Somerset and
Affiliated acquisitions as allowed under SFAS No. 115.

      Trading Securities - Debt and equity securities with readily determinable
market values that are bought and held principally for the purpose of selling
them in the near term are classified as trading securities and are carried at
fair value, with unrealized gains and losses included in current earnings. At
December 31, 1998 and 1997, there were no securities classified by the Company
as trading.

      Securities Available-for-Sale - Debt and equity securities not classified
as either held-to-maturity or trading are classified as available-for-sale and
carried at fair value, with unrealized gains and losses reported as a separate
component of stockholders' investment, net of tax. At December 31, 1998,
stockholders' investment included an unrealized gain of $7.6 million net of a
deferred tax provision of $5.3 million.

      For mortgage-backed securities, the Company recalculates the effective
yield on the investment to reflect the actual prepayment results and estimated
future prepayments. The net investment in these securities is adjusted to the
amount that would have existed had the new estimated average life and effective
yield been applied since the acquisition of the securities. Such adjustments are
reflected in interest income in the current period.


                                       40
<PAGE>   41

      The Company determines the securities sold by the specific identification
method. The amount of taxes paid on gains is dependent upon the overall results
of operations of the subsidiary realizing the gain. Realized gains and losses,
and declines in value judged to be other than temporary are included in
noninterest income as securities gains (losses).

Loans Held-for-Sale

Loans held-for-sale are carried at the lower of aggregate cost or market value
and included in other assets. Adjustments to market value and realized gains and
losses are classified as noninterest income. The balances of loans held-for-sale
were insignificant at December 31, 1998 and 1997.

Premises, Furniture and Equipment

Premises, furniture and equipment are stated at cost, less accumulated
depreciation and amortization. The Company provides for depreciation using the
straight-line method by charges to expense in amounts estimated to amortize the
cost over the estimated useful lives of the respective assets as follows:

<TABLE>

<S>                                                                  <C>
Buildings and building improvements                                  10-40 years
Computer equipment                                                     3-5 years
All other furniture and equipment                                     3-10 years
- --------------------------------------------------------------------------------
</TABLE>

Leasehold improvements are amortized over the life of the lease agreements.

Loans and Leases

Commercial and commercial real estate loans that are recognized by the Company
as nonaccrual and restructured are classified as "impaired loans" by the
Company. Consumer loans and lease financings recognized as nonaccrual are
collectively evaluated for impairment, and are excluded from impaired loans in
accordance with SFAS No. 114, "Accounting by Creditors for Impairment of a
Loan." Loan impairment is measured based on the present value of expected future
cash flows, discounted at the loan's effective interest rate or, as a practical
expedient, at the loan's observable market price or the fair value of the
collateral if the loan is collateral dependent.

      Loans are stated at their principal amount net of unearned discount, if
any. Certain loans are made on a discounted basis. The unearned discount
applicable to such loans is recorded as income monthly by use of the actuarial
method. Interest income on nondiscounted loans is accrued based on the principal
amount of loans outstanding. Loans and leases are placed on nonaccrual, with the
reversal of all uncollected accrued interest, when there is doubt as to the
collectibility of interest or principal or if loans or leases are 90 days or
more past due unless they are both well secured and in the process of
collection. In every case, a loan or lease reaching 180 days past due is placed
on nonaccrual. Interest received on impaired loans, nonaccrual leases and
nonaccrual consumer loans is applied to principal if collection of principal is
doubtful; otherwise, it is reflected in interest income on a cash basis.

      Restructured loans are those on which concessions in terms have been
granted as a result of deterioration of a borrower's financial condition and for
which doubt no longer exists as to collectibility of restructured principle or
interest. Interest on these loans is accrued at the new terms.

      Discount and premiums on purchased loans are amortized to income using the
interest method over the remaining period to contractual maturity, adjusted for
anticipated prepayments.

Reserve for Possible Loan Losses

The reserve for possible loan losses is maintained at a level considered
adequate by management to provide for possible losses from loans and leases.
Adequacy of the reserve is determined by management using a consistent,
systematic methodology which analyzes the size and risk of the loan and lease
portfolio. Factors 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. The
analysis includes sensitivity testing and supports a written conclusion. The
reserve is based on estimates, and ultimate losses may vary from current
estimates. These estimates are reviewed periodically and, as adjustments become
necessary, they are reported in earnings in the current period.

      When a loan, classified as impaired or otherwise, or a lease, 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. Amounts are charged off once the probability of loss has been
established, after having given consideration to such factors as level of
collateral and guarantees, prospective economic conditions and financial
strength of the customer.

          notes to consolidated financial statements, december 31, 1998

Other Property Owned

Other property owned consists of equipment, vehicles and other real estate owned
("OREO"). OREO includes properties acquired through foreclosure or in settlement
of loans. All OREO is held for sale and carried at the lower of the loan value
or fair value of the property acquired, less estimated costs to sell ("net
realizable value"). At the time of foreclosure, the excess, if any, of the loan
value over the net realizable value, is charged to the reserve for possible loan
losses. The carrying value of OREO is reviewed periodically. Subsequent declines
in the fair value of the property and net operating results of the property are
charged to foreclosed asset and workout expense.

      Other vehicles owned are acquired through repossession or in settlement of
loans or leases. Repossessed vehicles are carried at the lower of the net
investment in the loan or lease, or the estimated proceeds from insurance and
sale at auction.

      Other equipment owned is acquired through repossession or in settlement of
loans or leases. The equipment is carried at the lower of the net investment in
the loan or lease, or the estimated fair value of the equipment less estimated
selling costs.

Stock-based Compensation

On January 1, 1996, the Company adopted SFAS No. 123, "Accounting for
Stock-based Compensation," which establishes a fair value-based method of
accounting for stock options and similar equity instruments of employee stock
compensation plans. This Statement provides the option of adopting the new fair
value method or to continue to measure compensation cost for those plans using
the current intrinsic value-based method as prescribed by Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," ("APB No.
25"). Under this Statement, the continued use of the intrinsic value-based
method, requires pro forma disclosure of net income and earnings per share as if
the fair value-based method had been applied. The Company continues to use the
intrinsic value-based method under the provisions of APB No. 25 and has
disclosed the required pro forma information in Note 13.

Income Taxes

Deferred tax assets and liabilities are reflected at currently enacted income
tax rates applicable to the period in which the deferred tax assets or
liabilities are expected to be realized or settled. As changes in tax laws or
rates are enacted, deferred tax assets and liabilities are adjusted through the
income tax provision.

Intangible Assets

Intangible assets include goodwill and core deposit intangibles and are stated
at cost less accumulated amortization. Cost of purchased businesses in excess of
net assets acquired ("goodwill") includes amounts being amortized using lives
ranging from twelve- to twenty-five years with an insignificant amount at forty
years. Values assigned to deposits of purchased businesses ("core deposit
intangibles") are being amortized over seven- and fifteen-year periods using an
accelerated method.

      On a periodic basis, the Company reviews its goodwill and core deposit
intangible assets for events or changes in circumstances that may indicate that
the carrying amount of the assets may not be recoverable, and, if appropriate,
reduces the carrying amount through a charge to income in accordance with SFAS
No. 121, "Accounting for the Impairment of Long-lived Assets and for Long-lived
Assets to be Disposed of."

      Goodwill, net of accumulated amortization totaled $30.3 million and $32.8
million at December 31, 1998 and 1997, respectively. Core deposit intangibles,
net of accumulated amortization totaled $20.9 million and $24.9 million at
December 31, 1998 and 1997, respectively.

Statements of Cash Flows

For the purpose of reporting cash flows, cash and cash equivalents include cash
on hand, amounts due from banks and interest-bearing deposits.

Recent Accounting Developments

On January 1, 1998, the Company adopted Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130"), which
requires companies to report all changes in stockholders' investment during a
period, except those resulting from investment by owners and distribution to
owners, in a financial statement for the period in which they are recognized.
The Company has chosen, as allowed by SFAS No. 130, to disclose Comprehensive
Income, which encompasses net income and unrealized gains or losses on
securities available-for-sale, in the Consolidated Statements of Changes in
Stockholders' Investment. Prior years have been presented to conform to SFAS No.
130 requirements. The impact of this Statement for the year ended December 31,
1998 was to increase


                                       42
<PAGE>   43

reported net income of $55.3 million to a total comprehensive net income of
$59.7 million. The impact for the year ended December 31, 1997 was to increase
reported net income of $50.2 million to a total comprehensive net income of
$56.5 million and for the year ended December 31, 1996, a decrease from $56.6
million to $52.3 million.

      On December 31, 1998, the Company adopted SFAS No. 131, "Disclosures About
Segments of an Enterprise and Related Information." This Statement changes the
way public companies report segment information in annual financial statements
and requires public companies to report selected segment information in interim
financial reports to shareholders. Under the Statement's "management approach,"
public companies are to report financial and descriptive information about their
operating segments. Operating segments are components of an enterprise for which
separate financial information is produced internally and are subject to
evaluation by the chief operating decision maker in deciding how to allocate
resources to segments and assess segment performance. Refer to Note 3 for the
additional disclosures under this Statement.

      Also, on January 1, 1998, the Company adopted SFAS No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits." This Statement
does not change the recognition or measurement associated with pension or
postretirement plans. It standardizes certain disclosures, requires additional
information about changes in the benefit obligations and about change in the
fair value of plan assets to facilitate analysis, and it eliminates certain
disclosures that were not deemed useful. Refer to Note 12 for the disclosures
required under this Statement.

      In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position of 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use" ("SOP 98-1"). SOP 98-1
requires computer software costs associated with internal use software to be
expensed as incurred until certain capitalization criteria are met. SOP 98-1 is
effective for financial statements for fiscal years beginning after December 15,
1998. The Company does not believe that adoption of SOP 98-1 will have a
material impact on the Company's financial position or results of operations.

      In April 1998, the AICPA issued Statement of Position 98-5, "Reporting on
the Costs of Start-up Activities" ("SOP 98-5"). SOP 98-5 requires all costs
associated with pre-opening, pre-operating and organization activities to be
expensed as incurred. SOP 98-5 is effective for financial statements for fiscal
years beginning after December 15, 1998. The Company does not believe that

Instruments and Hedging Activities." This Statement establishes accounting and
reporting standards for derivative instruments and hedging activities. The
Statement is effective for all fiscal quarters of fiscal years beginning after
June 15, 1999. The Company does not expect that the adoption of this Statement
will have a material impact on the Company's financial position or results of
operations.

      In October 1998, the FASB issued SFAS No. 134, "Accounting for
Mortgage-Backed Securities Retained After the Securitization of Mortgage Loans
Held for Sale by a Mortgage Banking Enterprise." This Statement further amends
SFAS No. 65, "Accounting for Certain Mortgage Banking Activities," as amended by
SFAS No. 115 and SFAS No. 125. This Statement requires that after the
securitization of mortgage loans held for sale, an entity engaged in mortgage
banking activities classify the resulting mortgage-backed securities or other
retained interests based on its ability and intent to sell or hold those
investments. This Statement is effective for the first fiscal quarter beginning
after December 15, 1998. The Company does not expect that the adoption of this
Statement will have a material impact on the Company's financial position or
results of operations.

Brewer & Lord LLP - Pending

On December 17, 1998, the Company announced the execution of a definitive
agreement under which USTrust will acquire Brewer & Lord LLP, an independent
insurance agency headquartered in Norwell, Massachusetts. The purchase of Brewer
& Lord is structured as an all-cash transaction and is expected to close in the
second quarter of 1999. Through its nine offices, Brewer & Lord specializes in
providing personal, commercial and employee benefit-related insurance products
to consumers and medium-size and large business located primarily in eastern
Massachusetts. The acquisition is subject to the approval of the Massachusetts
Commissioner of Banks and the Massachusetts Commissioner of Insurance. Under the
agreement, Brewer & Lord will operate as a wholly-owned subsidiary of USTrust.

note 3. business segments

The Company provides a broad range of financial services to individuals and
small- and medium-sized companies. It services a single geographic area, the New
England region with its principal customer base in eastern Massachusetts. The
Company's operations include three reportable "operating segments," Retail
Banking, Commercial Banking and Treasury, all organized around products and
services. Retail Banking services include direct and indirect consumer loans and
leasing, consumer deposit products, residential loans, private banking and
mutual funds. Commercial Banking provides a broad range of financial services
principally to small- and medium-sized companies. Such services include
commercial lending, real estate financing, construction lending, cash management
services, merchant services, government banking and international trade
services. The Treasury group is charged with asset/liability risk management of
the Company, including the securities portfolio and interest-bearing
liabilities.

      The information presented herein includes allocations of income or expense
on excess funds used/provided at a market rate of interest to reflect the value
of the net funds each segment provides or uses in its operations. The rate is
applied without regard to differences in the risk profile of the operating
segments. A provision for possible loan losses is assigned to units involved in
credit extension based upon management's expectation of normalized losses.

      Operating expenses of the Company's support groups, including Data
Processing, Finance, Legal, Human Resources, among others, are charged to
business segments based on allocation criteria determined by the Company.

          notes to consolidated financial statements, december 31, 1998

state income taxes are applied using the Company's consolidated effective tax
rate. Assets of business segments that are net fund providers reflect the excess
funds sold balances in their respective asset balances while net funds users
reflect excess funds purchased as a part of liability balances. Expenditures for
additions to long-lived assets are not material. No one customer is responsible
for more than 10 percent of revenues. Operating segment interest income is
reported net of interest expense consistent with Company methodology.

      The historical financial results prior to merger and/or system conversions
of acquired institutions accounted for as poolings of interest are not combined
with the Company's operating segment results. Such segment information is not
readily determinable. Therefore, the operating segment financial information
presented is not indicative of segment results for a full year or any interim
period.

      Exhibited in the table below is selected financial information by
operating segment and a reconciliation of the reportable segment data to the
Company's consolidated total for each of the three years ended December 31,
1998.

          notes to consolidated financial statements, december 31, 1998

      Equity securities of the Federal Home Loan Bank ("FHLB") of Boston and
certain other securities, which do not have readily determinable market values
are carried at cost. USTrust is a member of the FHLB and is required to invest
in FHLB equity securities, a restricted investment, in an amount equal to the
greater of 1 percent of residential mortgage loans, including certain
mortgage-backed securities, or three-tenths of 1 percent of total assets or a
specified percentage of outstanding advances.

      The amortized cost and fair value of debt securities at December 31, 1998,
by contractual maturity, are shown in the table below. Actual maturities are
expected to differ from contractual maturities because some borrowers have the
right to prepay without penalty. Mortgage-backed securities are shown at their
final maturity but are expected to have shorter average lives. Equity
securities, which have no contractual maturity, are presented in the aggregate.

      There were no securities designated as held-to-maturity by the Company at
December 31, 1998. All of the year-end 1997 held-to-maturity securities were
owned by Somerset and Affiliated and were redesignated as available-for-sale at
their respective acquisition dates. The effect of the redesignation was to
increase the gross unrealized gain on securities available-for-sale by
approximately $1.9 million. The amortized cost, fair value and gross unrealized
gains and losses as of December 31, 1997 for securities held-to-maturity

</TABLE>

      Certain former officers and employees of Federal are included in a
noncontributory defined benefit pension plan as a participating employer in the
Financial Institutions Retirement Fund (the "Fund"), a multi-employer plan. The
Fund does not segregate its assets or liabilities by participating employer.
Contributions are based on the individual employer's experience. As the plan is
fully funded, no contribution is required. Benefits accrued under this plan
until September 30, 1998. Effective September 30, 1998, all future benefits are
earned under the Company's defined benefit retirement plan. In addition certain
former employees of Lexington and Federal are included in a non-qualified
supplemental retirement plan established by their respective banks. Each is
fully funded by life insurance; no contribution is required.

      The Company has an Employee Savings Plan which qualifies as a deferred
salary arrangement under Section 401(k) of the Internal Revenue Code. Under the
Plan, contributions made by eligible employees are matched by the Company at
varying rates based on a specified percentage of employee contributions. The
maximum match per employee by the Company is 4 percent of the individual
employee's earnings.

      During 1997 and 1996, the Company had an employee stock ownership plan
("ESOP") which covered substantially all of its employees. The plan was
administered by a committee designated by the Board of Directors and was
maintained in a separate trust established for that purpose. Under the plan, the
Company contributed either a fixed amount or a percentage of compensation of all
participants. Effective December 31, 1997, the ESOP ceased to operate as an
independent plan and was merged into a newly created Employer Stock Fund of the
Employee Savings Plan. All participants became vested in their ESOP account
balances, and these funds were transferred directly to their respective Employee
Savings Plan accounts.

      Certain former employees of Lexington and Federal receive benefits under
ESOP plans established by their respective banks. It is expected that these
plans, which have an insignificant effect on operating results of the Company,
will continue in accordance with their original terms.

      Certain key employees are awarded shares of the Company's common stock
through the Company's Restricted Stock Ownership Plan adopted in 1989 and the
restricted stock program of the Stock Compensation Plan adopted in 1992 and
amended in 1994. Under these restricted stock plans 631,320 shares of common
stock have been granted, of which 86,250, 32,100 and 14,400 were granted in
1998, 1997 and 1996, respectively. The shares vest to the employee over varying
schedules. In 1998, 44,549 restricted shares vested under this plan. At December
31, 1998 there were 100,901 unvested restricted shares outstanding.

      Expenses relating to the employee benefit plans were as follows:

note 13. stock options

The Company has a Stock Compensation Plan for officers and key employees under
the terms of which the Company may issue incentive stock options, nonqualified
stock options and shares of restricted stock. At December 31, 1998, 140,320
shares of the Company's common stock remained available for future grants. The
Company's Stock Compensation Plan provides that the number of shares of common
stock reserved for future grants under the plan be increased by an amount equal
to 1.25 percent of the number of shares outstanding on the first day of each
fiscal year. As a result, as of January 1, 1999, 535,302 additional common
shares are to be reserved for future grants. The vesting periods for options
under this Plan range from immediate vesting at grant date to 5 years. The
expiration periods for options under this Plan range from between 5 and 10
years.

      The Company has two stock option plans for directors, the 1996 Director
Option Plan and the 1995 Director Option Plan. Eligible directors received
option grants at fair value for 5,000 shares in 1996 and up to 7,500 shares in
1995. A total of 150,000 shares of the Company's common stock were reserved for
issuance under each plan. The vesting periods for options under these plans
range from immediate vesting at grant date to 3 years. The expiration periods
for options under these plans range from 5 to 10 years.

      The vesting periods for certain options under the aforementioned employee
and director plans can be accelerated in accordance with the plans based on
prescribed movement in the market price of the Company's stock or other
conditions. Under all option plans the option exercise price equaled the market
price of the Company's stock on date of grant.

      The Company has opted to continue to measure stock compensation in
accordance with APB Opinion No. 25. Refer to Note 1 for a further discussion. If
the Company had determined stock compensation cost consistent with the fair
value alternative contained in SFAS No. 123, the Company's net income and
earnings per share would have been reduced to the pro forma amounts presented in
the table below.

      The Company has a Directors Deferred Compensation Program under which up
to 250,000 shares of the Company's common stock may be granted to outside
Directors of the Company or its banking subsidiaries who choose to receive their
Director's fees or stipend in shares of the Company in lieu of cash. The shares
may not be sold until the individual holder's status as Director terminates.

note 14. noninterest expense

Restructuring Charges, Acquisition and Merger-related Expense Restructuring
charges for the year ended December 31, 1998 totaled $11.5 million. Such costs
were incurred in connection with the Somerset and Affiliated acquisitions and
were the result of management's integration plan. These costs related to
activities that had no future economic benefit to the Company and were
incremental to other costs incurred in the conduct of the Company's business.
The nature of these expenses included charges for severance payments to former
Somerset and Affiliated executives and staff, processing system conversions and
deconversion costs, customer communications related to the effect of the
acquisitions, write-offs of certain Somerset and Affiliated assets, and other
expenses directly associated with the integration of the acquired institutions.
Similar restructuring charges of $11.8 million for the year ended December 31,
1997 were incurred in connection with the Walden acquisition.

      Acquisition and merger-related expense for the year ended December 31,
1998 totaled $8.1 million which included professional, legal, accounting and
investment banking services incurred in connection with Somerset and Affiliated
acquisition transactions. Acquisition and merger-related expenses of $4.4
million for the year ended December 31, 1997 were incurred primarily in
connection with the Walden and Firestone acquisitions. For the year ended
December 31, 1996, the expense totaled $5.9 million, primary resulting from the
Branch Purchase.

      Reserves associated with restructuring and merger-related charges are
included in other liabilities and totaled $1.7 million and $.9 million at
December 31, 1998 and 1997, respectively. Additions to the reserve, as described
above, of $11.5 million and $11.8 million for the years ended December 31, 1998
and 1997, respectively, were charged to income. Cash expenditures and write-offs
of $10.7 million and $14.6 million in 1998 and 1997, respectively, were charged
against the reserve balance.

Deposit Insurance Assessment

The Company's deposit insurance assessment reflects premiums paid to two Federal
Deposit Insurance Corporation ("FDIC") funds, the Bank Insurance Fund ("BIF")
for banks, as well as the Savings Association Insurance Fund ("SAIF") for
savings and loan associations ("Thrifts"), due to the Company's acquisitions of
thrift deposits and thrift institutions. The deposit insurance assessment for
the years ended December 31, 1998 and 1997 reflect reductions in expense due to
reduced premium rates by the FDIC on BIF balances. The year ended December 31,
1996, included a $5 million one-time assessment by the SAIF on the former Thrift
deposits held by the Company.

          notes to consolidated financial statements, december 31, 1998
          -------------------------------------------------------------

      As of December 31, 1998 and 1997, cumulative deferred tax assets, included
in the consolidated balance sheets as other assets, amounted to $18.5 million
and $14.7 million, respectively, while cumulative deferred tax liabilities of
$1.3 million and $0.4 million, respectively, were included in other liabilities.
Additionally, at December 31, 1998 and 1997 there were tax refund receivables of
approximately $1.7 million and $2.2 million included in other assets while
current taxes payable were approximately $11.5 and $4.5 million, respectively,
and included in other liabilities.

      In August 1996, Congress passed the Small Business Job Protection Act of
1996. Included in this bill was the repeal of Internal Revenue Code (IRC)
Section 593, which allowed thrift institutions special provisions in calculating
bad debt deductions for income tax purposes. Thrift institutions are now viewed
as commercial banks for income tax purposes. The repeal is effective for tax
years beginning after December 31, 1995. One effect of this legislative change
is to suspend a thrift's bad debt reserve for income tax purposes as of its base
year (December 31, 1988). Any bad debt reserve in excess of the base year amount
is subject to recapture over a six-year time period. The suspended (i.e., base
year) amount is subject to recapture upon the occurrence of certain events, such
as a complete or partial redemption of a bank's stock or if the bank ceases to
qualify as a bank for income tax purposes.

      Through the Company's acquisition of Walden, Somerset and Affiliated and
subsequent merger of the various banking subsidiaries with USTrust in 1997 and
1998, USTrust's tax position is effected by this legislative change. At December
31, 1998, USTrust's surplus includes approximately $37.0 million of bad debt
reserves, representing the base year amount, for which income taxes have not
been provided. Since USTrust does not intend to use the suspended bad debt
reserve for purposes other than to absorb the losses for which it was
established, deferred taxes in the amount of $15.5 million have not been
recorded with respect to such reserve.

      The components of the net deferred tax asset were as follows:

note 16. earnings per share

The Company computes earnings per share in accordance with SFAS No. 128. This
Statement supersedes APB No. 15 regarding the presentation of earnings per share
("EPS") on the face of the income statement. SFAS No. 128 replaced the
presentation of Primary EPS with a Basic EPS calculation that excludes the
dilutive effect of 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 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,
including quarterly information. The Company's common stock equivalents consist
primarily of dilutive outstanding stock options and restricted stock grants
computed under the treasury stock method. Basic and Diluted EPS for the three
years ended December 31, 1998, 1997 and 1996 are as follows:

note 17. capital

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 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

          notes to consolidated financial statements, december 31, 1998
          -------------------------------------------------------------

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 1 capital (as defined in
the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as
defined) to average assets (as defined). Management believes, as of December 31,
1998, that the Company and its subsidiary banks meet all of their respective
capital adequacy requirements.

      The actual capital amounts and ratios of the Company and its banking
subsidiaries are presented in the following summary.

Dividends

The Company and its banking subsidiaries' ability to pay dividends is subject to
certain limitations imposed by statutes of the Commonwealth of Massachusetts and
limitations imposed by bank and bank holding company regulators. Massachusetts
statutes restrict the amount of dividends payable by banks to be the balance of
their undivided profits, net of any amount transferred to capital in excess of
par value. An issuance of dividends which would reduce the capital of the
Company and/or its Subsidiary Banks below minimum capital requirements would
cause the appropriate regulatory agencies to require the institution to submit
an acceptable capital restoration plan. An institution which fails to submit an
acceptable plan may be subject to a bank regulatory enforcement action, or
ultimately placed into conservatorship or receivership.

      In 1998 the Company declared quarterly cash dividends totaling $23 million
or $0.54 per share to stockholders. During the year the Company's subsidiaries
declared dividends payable to the Company totaling $37 million.

Shareholder Rights Plan

      In 1995, the Company's Board of Directors approved a Shareholder Rights
Plan and distributed preferred share purchase rights to shareholders. The rights
will become exercisable only if a person or group (i) acquires 15 percent or
more of the Company's common stock, (ii) announces a tender offer that would
result in ownership of 15 percent or more of the common stock, or (iii) is
declared to be an "Adverse Person" by the Company's Board of Directors. "Adverse
Person" includes any person or group who owns at least 10 percent of the
Company's common stock and attempts an action that would adversely impact the
Company. Each right would entitle a stockholder to purchase 1/100th of a share
of a new series of junior participating preferred stock.

      Once a person or group has acquired 15 percent or more of the outstanding
common stock of the Company or is declared an "Adverse Person" by the Company's
Board of Directors, each right may entitle its holder (other than the acquiring
person or Adverse Person) to purchase, at an exercise price of $40, shares of
common stock of the Company (or any organization that acquires the Company) at
an amount equal to 50 percent of their current market price. Under certain
circumstances, the Continuing Directors (as defined in the rights plan) may
exchange the rights for common stock (or equivalent securities) on a one-for-one
basis excluding rights held by the acquiring person or Adverse Person. The
rights may be redeemed by action of the Board of Directors for $.001 per right.

Stock Repurchase Programs

      In November 1998, the Company's Board of Directors approved a common stock
repurchase program authorizing the repurchase of up to 310,000 shares which
constitutes less than 1 percent of the Company's common stock outstanding. The
repurchase program did not affect the Company's use of the pooling of interests
method of accounting to record the recent acquisitions by the Company of
Affiliated and Somerset since it was implemented in accordance with the
Securities and Exchange Commission's Staff Accounting Bulletin No. 96. The
program authorizes the Company to buy back common stock from time to time,
subject to prevailing market conditions. Purchases may be made on the open
market or in privately negotiated transactions. As of December 31, 1998, 103,500
shares had been purchased under the program, 23,049 shares were reissued and
80,451 shares remained in treasury.

      Prior to the August 7, 1998 acquisition of Affiliated by the Company,
Affiliated retired all of its common stock held in treasury (total of 348,975
UST Corp. equivalent shares) and terminated its stock repurchase program.

note 18. related party transactions

In the ordinary course of business, the Company's banking subsidiaries have
granted loans to certain of the Company's directors and executive officers. All
such transactions are made on substantially the same terms as those prevailing
at the same time for individuals not affiliated with the Company and its
subsidiaries and at the time they were granted did not involve more than the
normal risk of collectibility. At December 31, 1998, none of these transactions
were on nonaccrual status, nor did they involve delinquent, substandard or
restructured loans. Over 77 percent of the balance outstanding at December 31,
1998 and 1997 was due from one director.

      Rent expense for the years ended December 31, 1998, 1997 and 1996 was
approximately $6.6 million, $6.1 million, and $5.0 million, respectively.

      In the ordinary course of business, the Company and its subsidiaries
become defendants in a variety of judicial and administrative proceedings. In
the opinion of management there is no proceeding pending, or to the knowledge of
management threatened, which in the event of an adverse decision, would result
in a material adverse change in the financial condition or results of operations
of the Company.

note 20. financial instruments with on-and off-balance sheet risk

The Company is party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of its customers. These
financial instruments include commitments to extend credit, standby letters of
credit and financial guarantees, foreign exchange contracts, and recourse
arrangements on sold loans. Those instruments involve, to varying degrees,
elements of credit risk in excess of the amount contained in the balance sheet.
The contract or notional amounts of those instruments reflect the extent of
involvement the Company has in particular classes of financial instruments.

      The Company's exposure to credit loss in the event of nonperformance by
the other party to the financial instrument or commitments to extend credit and
standby letters of credit and financial guarantees written is represented by the


                                       62

contractual notional amount of those instruments. The Company uses the same
credit policies in making commitments and conditional obligations as it does for
on-balance sheet instruments.

      The Company generally requires collateral or other security to support
financial instruments with credit risk.

      Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract during its
term. Commitments generally have fixed expiration dates or other termination
clauses and usually require payment of a fee. Since many of the commitments are
expected to expire without being fully drawn upon, the total commitment amounts
do not necessarily represent future cash requirements. The Company evaluates
each customer's credit worthiness on a case-by-case basis. Of the total
commitments to extend credit, approximately $258 million and $276 million were
secured by real estate at December 31, 1998 and December 31, 1997, respectively.

      The amount of collateral obtained is based on management's evaluation of
the credit risk. Collateral held on commitments and loans varies but may include
cash, accounts receivable, inventory, property, plant and equipment. Standby and
commercial letters of credit and financial guarantees written are conditional
commitments issued by the Company to guarantee the performance of, or payment
by, a customer to a third party. Those guarantees are primarily issued to
support private borrowing arrangements. The credit risk involved in issuing
letters of credit is essentially the same as that involved in extending loan
facilities to customers. The Company holds various collateral to support these
commitments including (but not limited to) cash, account receivables, inventory,
property, plant and equipment. The extent of collateral held for those
commitments varies from zero to over one hundred percent. Of the total standby
and commercial letters of credit, approximately $13 million was secured by real
estate at December 31, 1998.

      The Company's primary loan market is the New England region. Most of the
loans outstanding are from eastern Massachusetts and a substantial portion of
these loans are various types of real estate loans; still others have real
estate as additional collateral. Approximately 79 percent of the Company's
outstanding commercial and commercial real estate loans are collateralized.

      The Company enters into foreign currency exchange contracts to purchase or
sell foreign currencies at a future date at a predetermined exchange rate.
Except as noted below, contracts are purchased on the open market to assist
customers with international transactions denominated in foreign currencies. The
Company is exposed to credit risk in the event the customer fails to deliver or
take delivery of the agreed upon currency whereby the Company would execute the
transaction with another counterparty at the prevailing currency valuation. The
positive fair value, which represents the credit exposure of contracts
outstanding, was insignificant at December 31, 1998 and 1997.

      The Company enters into nominal amounts of foreign exchange contracts for
the purposes of hedging certain financial commitments related to the collection
of loans of Canadian borrowers. The fair value of such contracts was
insignificant at December 31, 1998 and 1997.

      During 1997, the Company, through its small equipment finance company,
Firestone, was party to an interest rate swap agreement with a nominal notional
amount. The swap agreement effectively converted a portion of Firestone's
interest rate obligation on certain long-term borrowings from a floating to a
fixed rate. The arrangement was paid in full and terminated in August 1997,
prior to the acquisition of Firestone by the Company.

      The Company's securities portfolio includes a significant investment in
mortgage-backed securities. These securities carry prepayment risk due to the
fact that prevailing interest rates could decline. Under such circumstances an
unusually high percentage of homeowners may choose to refinance their first
mortgages to take advantage of these lower rates with the result that, under the
Company's accounting policy, adjustments reducing gross unamortized premiums
would be required. Refer to Note 1 for a discussion of accounting policies.

note 22. financial instruments

SFAS No. 107, "Disclosures about Fair Value of Financial Instruments," requires
disclosure of the fair market value of Financial Instruments (as defined),
whether assets, liabilities or off-balance sheet commitments, if practicable.
The following methods and assumptions were used to estimate the fair value of
each class of Financial Instruments. Fair value estimates which were derived
from discounted cash flows or broker quotes cannot be substantiated by
comparison to independent markets and, in many cases, could not be realized in
immediate settlement of the instrument.

          notes to consolidated financial statements, december 31, 1998

      Cash and due from banks, federal funds sold and other short-term
investments - For these short-term instruments the carrying amount is a
reasonable estimate of fair value.

      Securities available-for-sale and securities held-to-maturity - For
marketable securities fair values are based on quoted market prices or dealer
quotes.

      Loans - For certain homogeneous categories of loans, such as residential
mortgages and home equity loans, fair value is estimated based on broker quotes
on sales of similar loans. The fair value of fixed rate loans was estimated by
discounting anticipated future cash flows using current rates at which similar
loans would be made to borrowers with similar credit ratings and for the same
remaining maturities. The fair value of performing variable rate loans is the
same as the book value at the reporting date because the loans reprice when the
market changes.

      Deposit liabilities - The fair value of noncertificate deposit accounts is
the amount payable on demand at the reporting date. The fair value of
fixed-maturity certificates of deposit is estimated by discounting the
anticipated future cash payments using the rates currently offered for deposits
of similar remaining maturities.

      Short-term borrowings - For these short-term instruments the carrying
amount is a reasonable estimate of fair value.

      Other borrowings - The fair value for FHLB borrowings with an original
maturity of greater than one year was determined by discounting the expected
cash flows using a discount rate equal to the current rate offered by the FHLB
for debt of the same remaining maturity. While the current FHLB debt outstanding
has a prepayment option at the borrower's discretion, the fair value was
estimated assuming the Company will hold the full amount until maturity.

      Off-balance sheet financial instruments - For commitments to extend
credit, standby and commercial letters of credit and foreign exchange contracts,
the carrying amount which represents accruals of deferred income (fees) arising
from these instruments, and the fair value of such deferred income is not
material. Refer to Note 20 for notional or contract amounts and a further
discussion of off-balance sheet financial instruments.

      Values not determined - SFAS No. 107 excludes certain assets from its
disclosure requirements including real estate included in banking premises and
equipment, lease financings, and the intangible value inherent in the Company's
deposit relationships (i.e., core deposits). Accordingly, the aggregate fair
value amounts presented below do not represent the underlying value of the
Company.

      The carrying amount and estimated fair values of the Company's Financial
Instruments at December 31, 1998 and 1997 are as follows:

</TABLE>

Quarterly net income and diluted earnings per share, while affected by large
infrequent items and the addition of Year 2000 readiness expense in 1998, grew
throughout most of the two-year period. Acquisition and merger-related expenses
and restructuring charges totaling $14.6 million and $19.6 million were incurred
in the first quarter 1997 and third quarter 1998, respectively. Excluding these
charges, diluted earnings per share were $0.35 in first quarter 1997 and $0.39
diluted earnings per share in the third quarter 1998. Large realized gains on
sale of securities and loans positively affected earnings results in the first
quarter 1997, first quarter 1998, and third and fourth quarters 1998.

      The two years ended December 31, 1998 was a period of strong growth in net
interest income. Earning asset growth and favorable changes in deposit mix and
reduced deposit and borrowing costs were the largest factors for the improving
margin. The quarterly provision for possible loan losses averaged approximately
$1 million during the two-year period as asset quality remained favorable. The
exception was a $.9 million credit provision recorded in the second quarter of
1998. A credit provision, or reduction in loan loss reserve was recorded by
Somerset Savings Bank prior to acquisition by the Company.

      Noninterest income fueled by strong growth in asset management fees,
deposit account service charges and corporate services income, increased during
most of the eight quarter periods. Peak quarters were first quarter 1997 and
first, third and fourth quarter of 1998 due to realized gains on securities and
loan sales of $2.1 million, $1.4 million, $1.1 million, and $1.5 million,
respectively.

      In order to support volume growth throughout the Company as well as
support and process the many system conversions and mergers of five banks,
noninterest expenses rose during the eight-quarter period. Acquisition and
merger-related expenses and restructuring charges were recorded in the first,
third, and fourth quarters of 1997 and third quarter of 1998 of $14.6 million,
$1.0 million, $.6 million, and $19.6 million, respectively. In addition, during
1998 the Company incurred Year 2000 readiness expense in quarters one through
four of $.5 million, $.8 million, $1.8 million, and $2.3 million, respectively.

                      Office of the Chief Executive Officer

      In 1987, the Board of Directors of the Company created an Office of the
Chief Executive Officer ("OCEO") (formerly known as the Executive Policy
Committee) which is the primary management forum of the Company for all
strategic and policy decisions. Such decisions of the OCEO are subject to the
review and approval of the Board of Directors of the Company. The OCEO has been
directed by the Board of Directors to make recommendations to the Board
concerning adoption of policies, strategies and programs concerning the
following, among other matters: (a) acquisitions and dispositions of corporate
entities, assets and/or investments; (b) the issuance of equity and/or debt; (c)
engaging in new business activities; (d) the hiring, termination, training and
motivation of senior management; (e) the development of marketing programs
concerning financial services; (f) improvements to operations, service delivery
and implementation of procedures for cost control; (g) improvements to the
financial reporting and financial control systems; (h) improvements to the
business information systems; and (i) improvements concerning risk management
and legal and regulatory compliance programs. As of March 1, 1999, there were 7
members of the OCEO. The members of the OCEO are identified and the background
of each OCEO member is set forth below under "Executive Officers."

                               Executive Officers

      The names and ages of the executive officers of the Company (all of whom
are members of the OCEO) and each executive officer's position with the Company
and its principal subsidiaries are listed below. Each such executive officer is
elected annually by the Directors of the Company (or the Directors of the
applicable subsidiary of the Company) and serves until his or her successor is
duly chosen and qualified or until his or her earlier death, removal or
disqualification.

knowledge of Seller, threatened, against Seller or the Seller Subsidiary or
challenging the validity or propriety of the transactions contemplated by this
Agreement or the Plan of Merger, as to which there is a reasonable probability
of an adverse determination and which, if adversely determined, would,
individually or in the aggregate, have a Material Adverse Effect on Seller or
otherwise materially adversely affect Seller's ability to perform its
obligations under this Agreement, nor is there any judgment, decree, injunction,
rule or order of any legal or administrative body or arbitrator outstanding
against Seller having, or which insofar as reasonably can be foreseen, in the
future could have, any such effect.

      4.10 Taxes and Tax Returns.

      (a) Seller and the Seller Subsidiary (referred to for purposes of this
Section 4.10, collectively, as the "Companies") have timely filed in correct
form all Filed Tax Returns, each Filed Tax Return has been prepared in
compliance with all applicable laws and regulations, and all Filed Tax Returns
are true and accurate in all respects. Seller has delivered to the Buyer correct
and complete copies of all federal income Tax Returns filed with respect to the

<PAGE>   13

consented to any extension of the period for assessment or collection with
respect to any Tax. No Filed Tax Return of either of the Companies is now under
examination by any applicable taxing authority. There are no liens for Taxes
(other than current Taxes not yet due and payable) on any of the assets of
either of the Companies. Neither of the Companies has requested or been granted
an extension of the time for filing any Tax Return to a date later than the
Effective Time. No claim has ever been made by a taxing authority in a
jurisdiction where neither of the Companies pays Tax or file Tax Returns that
either of the Companies is or may be subject to Taxes assessed by that
jurisdiction.

each of Seller and the Seller Subsidiary for all Taxes of such Company in

under Code Sections 108(b)(5), 338(g), or 565, or Treasury Regulation

      (i) The Companies have withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any Partner,
Retired Partner, employee, creditor, independent contractor or other third
party.

knowledge of Seller, threatened, against Seller or the Seller Subsidiary which
would have a Material Adverse Effect on Seller or Buyer. Except as set forth in

(v) most recent annual report on Form 5500.

      (c) The current value of the assets of each of the Seller Pension Plans
subject to Title IV of ERISA is less than that plan's "benefit liabilities" as
that term is defined in Section 4001(a)(16) of ERISA, when determined under
actuarial factors that would apply if that plan terminated in accordance with
all applicable legal requirements.

      (d) Each of the Seller Pension Plans and each of the Seller Benefit Plans

plan, program or arrangement will irrevocably continue, with respect to any or
all of its participants, for any period of time.

      4.12 Agreements with Governmental Authorities. None of Seller, the Seller
Subsidiary, or any of the Partners or Associates is a party to any commitment,
letter, written agreement, memorandum of understanding or order to cease and
desist with any federal or state governmental agency or authority charged with
the supervision or regulation of insurance agencies which restricts the conduct
of its business, or in any manner relates to its capital adequacy, credit
policies or practices, management or overall safety and soundness or such
entity's ability to perform its obligations hereunder. 

      4.13 Material Agreements. Section 4.13 of the Seller Disclosure Schedule
lists the following contracts and other agreements (whether written or oral) to
which either of Seller or the Seller Subsidiary is currently a party:

            (i) any agreement (or group of related agreements) for the lease of
      personal property to or from any Person providing for lease payments in
      excess of $25,000 per annum;

            (vi) any agreement with any Partner or any Affiliate;

            (vii) any profit sharing, option, partnership or stock purchase,
      deferred compensation, severance or other plan or arrangement for the
      benefit of its current or former Partners, officers and employees;

            (viii) any agreement for the employment of any individual on a
      full-time, part-time, consulting or other basis or providing severance
      benefits;

            (ix) any agreement under which it has advanced or loaned any amount

      ordinary course of business;

            (x) any agreement under which the consequences of a default or
      termination could have a Material Adverse Effect on Seller, indicating any
      such agreement which is subject to renewal within sixty (60) days of the

            (xi) any other agreement (or group of related agreements), other
      than contracts for insurance, the performance of which involves the
      payment by Seller of consideration in excess of $25,000.

      Seller has delivered to the Buyer a correct and complete copy of each
written agreement listed in Section 4.13 of the Seller Disclosure Schedule and a
written summary setting forth the terms and conditions of each oral agreement,
if any, referred to in Section 4.13 of the Seller Disclosure Schedule. Each such
written agreement constitutes the legal, valid and binding obligation of the
parties thereto, enforceable against such obligor in accordance with the terms
thereof (except as enforcement may be limited by general principles of equity
whether applied in a court of law or equity and by bankruptcy, insolvency and
similar laws affecting creditors' rights and remedies generally). Seller is not
in default under, or with the giving of notice or the lapse of time, or both,
would be in default under, any of the terms or conditions of any contract,
agreement or commitment listed in Section 4.13 of the Seller Disclosure
Schedule. To the knowledge of any of the Partners and Seller's officers, there
has occurred no default or event which, with the giving of notice or the lapse
of time, or both, would constitute a default by any other party to any such
contract, agreement or commitment.

      4.14 Ownership of Real Property and Assets; Leases. Neither Seller nor the
Seller Subsidiary owns any real property. Section 4.14(a) of the Seller
Disclosure Schedule sets forth a true and complete list of all real property
leased or operated by the Seller or the Seller Subsidiary as of the date hereof.
Seller or the Seller Subsidiary, as the case may be, has good and marketable
title to all assets and properties used in its respective business, whether real
or personal, tangible or intangible, including, without limitation, the assets
and properties reflected in its respective balance sheet as of September 30,
1998, or acquired subsequent thereto, subject to no encumbrances, liens,
mortgages, security interests or pledges, except (a) those items that secure
liabilities that are reflected in said balance sheet or the notes thereto or
incurred in the ordinary course of business after the date of such balance sheet
or (b) statutory liens for amounts not yet delinquent or which are being
contested in good faith. Seller or the Seller Subsidiary, as the case may be, as
lessee has the right under valid and existing leases to occupy, use, possess and
control all property leased by the Seller or the Seller Subsidiary as presently
occupied, used, possessed and controlled by the Seller or the Seller Subsidiary.
Neither Seller nor the Seller Subsidiary is in default, and there has not
occurred any event that with the lapse of time or giving of notice or both would
constitute a default, under any leases pursuant to which the Seller or the
Seller Subsidiary leases any real property, except for such defaults which,
individually or in the aggregate, would not result in the forfeiture of the use
or occupancy of the property covered by any such lease or would not result in a
material liability to the Seller or the Seller Subsidiary which is not reflected
on the consolidated balance sheet of the Seller dated as of September 30, 1998.
All such leases constitute legal, valid and binding obligations of the Seller or
the Seller Subsidiary and, to the knowledge of the Seller, the other party
thereto, enforceable by the Seller or the Seller Subsidiary in accordance with
their respective terms, except that enforcement thereof may be limited by the
receivership, conservatorship and supervisory powers of bank regulatory agencies
generally as well as bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting enforcement of creditors' rights generally and except
that enforcement thereof may be subject to general principles of equity
(regardless of whether enforcement is considered in a proceeding in equity or at
law) and the availability of equitable remedies. Section 4.14(a) of the Seller
Disclosure Schedule sets forth the expiration date and renewal terms of each
such lease. Neither Seller nor the Seller Subsidiary has received notice of, or
made a claim with respect to, any breach or default under any leases pursuant to
which the Seller or the Seller Subsidiary leases any real property. None of the
leases to which 
<PAGE>   16
the Seller or the Seller Subsidiary is a party, will terminate by reason of the
Seller (a) entering into this Agreement or any of the other Transaction
Documents or (b) consummating the transactions contemplated hereby or thereby.

      4.15 Reports. Since January 1, 1994, Seller and the Seller Subsidiary have
filed, and subsequent to the date hereof will file, all reports, registrations
and statements, together with any amendments required to be made with respect
thereto, that were and are required to be filed with any state or federal
governmental agencies or authorities (all such reports and statements are
collectively referred to herein as the "Seller Reports"). As of their respective
dates, the Seller Reports complied and, with respect to filings made after the
date of this Agreement, will at the date of filing comply, in all material
respects with all of the statutes, rules and regulations enforced or promulgated
by the regulatory authority with which they were filed and did not contain and,
with respect to filings made after the date of this Agreement, will not at the
date of filing contain, any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

      4.16 Compliance with Applicable Laws. Each of Seller, the Seller
Subsidiary, the Partners and the Associates holds all material licenses,
franchises, permits and authorizations necessary for the lawful conduct of its
and their respective business and activities, and each of Seller, the Seller
Subsidiary, the Partners and the Associates has complied with and is not in
default in any respect under any applicable law, statute, order, rule,
regulation or policy of, or agreement with, any federal, state or local
governmental agency or authority relating to Seller, the Seller Subsidiary, the
Partners and the Associates, other than where such default or noncompliance will
not result in, or create any reasonable probability of resulting in, a material
limitation on the conduct of the business of Seller or the Seller Subsidiary,
will not cause, or create any reasonable probability of causing, Seller, the
Seller Subsidiary, the Partners or the Associates to incur any material
financial penalty and will not otherwise result, or create any reasonable
probability of resulting, with respect to Seller, in any Material Adverse
Effect, and, except with respect to those matters for which Seller has provided
Buyer information pursuant to Section 4.09 hereof, Seller has not received any
notice of violation of, or commencement of any proceeding in connection with any
such violation, and does not know of any violation of, any such law, statute,
order, rule, regulation, policy or agreement which would have such a result.

      4.17 Insurance. Seller and the Seller Subsidiary are presently insured,
and since December 31, 1993 have been insured, for reasonable amounts against
such risks as companies engaged in a similar business in a similar location
would, in accordance with good business practice, customarily be insured. Seller
has delivered to the Buyer copies of policies relating to insurance maintained
by the Seller or the Seller Subsidiary with respect to their properties and the
conduct of their businesses.

      4.18 Labor. No work stoppage involving Seller or the Seller Subsidiary is
pending or, to the best knowledge of Seller, threatened. Neither Seller nor the
Seller Subsidiary is involved in, or, to the best knowledge of Seller,
threatened with or affected by, any dispute, arbitration, lawsuit or
administrative proceeding relating to labor or employment matters which, if
adversely decided, could result in a Material Adverse Effect with respect to
Seller.

      4.19 Material Interests of Certain Persons. No officer, director,
employee, or Partner of Seller or the Seller Subsidiary, as the case may be, or
any "associate" (as such term is defined in Rule 14a-1 under the Exchange Act)
of any such officer, director, employee or Partner, has any material interest in
any material contract or property (real or personal), tangible or intangible,
used in or pertaining to the business of Seller or the Seller Subsidiary.

      4.20 Trademarks, Patents, Etc. Neither Seller nor the Seller Subsidiary
has or uses any patents, trade names, service marks, trademarks or copyrights
registered in its name. Seller does not have or use any common law trade names
or trademarks or copyrights or any proprietary trade secrets, processes or
know-how except for (i) the use by it of the names listed in Section 4.20 of the
Seller 
<PAGE>   17
Disclosure Schedule, (ii) copyrights arising by operation of law in connection
with brochures and other written material created by Seller and (iii) any
customer lists of Seller or the Seller Subsidiary (the "Known Intellectual
Property"). Except for off-the-shelf office systems programs or as described in
Section 4.20 of the Seller Disclosure Schedule, neither Seller nor the Seller
Subsidiary is a party to any license agreement as licensor or licensee of any
intellectual property. Seller has not granted to any other Person a license of
any of the names listed in Section 4.20 of the Seller Disclosure Schedule or any
derivation thereof. No claims have been asserted against Seller or the Seller
Subsidiary, and to the Seller's knowledge no claims are pending, by any Person
regarding the use or infringement by Seller or the Seller Subsidiary of any
trademarks, patents, service marks, trade names, copyrights, trade secrets,
know-how or processes or other intellectual property of any kind whatsoever, or
challenging or questioning the validity or effectiveness of any license or
agreement, and to the Seller's knowledge there is no basis for such claim. To
the Seller's knowledge, the use by Seller or the Seller Subsidiary of the Known
Intellectual Property does not infringe on the rights of any Person.

      4.21 Accounts Receivable. Except as specifically set forth in Section 4.21
of the Seller Disclosure Schedule, hereto, all accounts and notes receivable
reflected on the Seller Balance Sheet, and all accounts and notes receivable
arising subsequent to the date of the Seller Balance Sheet, have arisen in the
ordinary course of business, represent valid obligations to Seller or the Seller
Subsidiary and, subject only to an amount of bad debts reasonable in the
industry and not materially different than Seller's past experience, have been
collected or are collectible in the aggregate recorded amounts thereof in
accordance with their terms.

commissions, and, for the nine months ended September 30, 1998, accounted for
6.1% of Seller's gross commissions and (ii) as of the date hereof, Expirations

      4.25 Year 2000. The only "mission-critical" computer system (as such term
is commonly used in regulations and trade organization guidelines with respect
to the Year 2000 Problem (as defined below)) owned or utilized by Seller in its
business is the "INfinity System". Seller has scheduled an update to the
INfinity System in January 1999. Seller has received written assurances from
Delphi Product Development, the applicable third-party service provider with
respect to the INfinity System, that upon adoption of the update referred to in
the preceding sentence, the INfinity System will contain no deficiencies
relating generally to formatting for entering dates (commonly referred to and
referred herein as the "Year 2000 Problem") and that the INfinity System is in
compliance with all regulations and trade organization guidelines concerning the
Year 2000 Problem. To the best of Seller's knowledge, all of its other computer
systems ("Non-Mission Critical Systems") are in compliance with all regulations
and trade organization guidelines concerning the Year 2000 Problem, except where
the failure to be compliant would not result in, with respect to Seller, any
Material Adverse Effect. Seller is in the process of requesting written
assurances from all applicable third-party service or equipment providers that
its Non-Mission Critical Systems are in compliance with all regulations and
trade organization guidelines concerning the Year 2000 Problem. Seller has
delivered to Buyer copies of all correspondence between Seller and third-party
service or equipment providers or licensors concerning Year 2000 Problem
compliance. Except as set forth in Section 4.25 of the Seller Disclosure
Schedule, and except for off-the-shelf office systems programs, Seller has no
other contracts with, or commitments to, any third-party with respect to its
computer systems. Seller is not aware of any inability on the part of any
customer, insurance company or service provider with which Seller transacts
business to timely remedy any deficiencies of its own in respect of the Year
2000 Problem.

      4.26 Prior Acquisitions. Except as set forth in the Seller Balance Sheet,

were incurred or outstanding in connection with any acquisitions made by Seller
prior to the date of this Agreement.

      4.27 Seller Information. The information relating to the Seller and the
Seller Subsidiary to be contained in any documents filed with any governmental

Agreement, and no statement contained in any certificate, list or other writing,
including but not necessarily limited to the Seller Disclosure Schedule,
furnished to Buyer pursuant to the provisions hereof, to the best knowledge of
Seller, contains or will contain any untrue statement of a material fact or
omits to state a material fact necessary in order to make the statements herein
or therein not misleading or, in the case of Seller's and the Seller
Subsidiary's financial statements, to present fairly the assets, liabilities and
partners' accounts of Seller and its business and expenses, changes in partners'
accounts and cash flows. To the best knowledge of Seller, all information
material to Buyer's interest in the Merger, or which is necessary to make

copies of all correspondence between Seller and such third-parties regarding the

      5.02 Access to Properties and Records; Confidentiality.

      (a) Except as provided below, once a public announcement of this Agreement
has been made, Seller shall permit Buyer access to its and the Seller
Subsidiary's properties during normal business hours upon reasonable prior
notice, and shall disclose and make available to Buyer all Records, including
all books, papers and records relating to the assets, partnership interests,
stock ownership, properties, operations, obligations and liabilities of Seller
and the Seller Subsidiary, including, but not limited to, all books of account
(including the general ledger), tax records, minute books of Partners',
directors' and stockholders' meetings, organizational documents, by-laws,
material contracts and agreements, filings with any regulatory authority,
accountants' work papers, litigation files, plans affecting employees, and any
other business activities or prospects in which Buyer may reasonably have an
interest in light of the 
<PAGE>   23
transactions contemplated hereby. Seller shall use best efforts to make
arrangements with each third party provider of services to Seller or the Seller
Subsidiary to permit Buyer reasonable access to all of Seller's and the Seller
Subsidiary's Records held by each such third party. Buyer shall permit Seller
reasonable access during normal business hours upon reasonable prior notice to
such properties and records of Buyer in which Seller may reasonably have an
interest in light of the transactions contemplated hereby. Neither Buyer nor
Seller shall be required to provide access to or to disclose information where
such access or disclosure would violate or prejudice the rights of any customer,
would jeopardize the attorney-client privilege of the institution in possession
or control of such information, or would contravene any law, rule, regulation,
order, judgment, decree or binding agreement or, in the event of any litigation
or threatened litigation between the parties over the terms of this Agreement
where access to information may be adverse to the interests of such party. The
parties will use all reasonable efforts to make appropriate substitute
disclosure arrangements under circumstances in which the restrictions of the
preceding sentence apply.

      (b) All Confidential Information, as such term is defined further below,
furnished by each party hereto to the other or to any of its affiliates or to
any of its or any of its affiliates' directors, officers, employees, or
representatives or agents (such persons being referred to herein as
"Representatives"), shall be treated as the sole property of the party
furnishing the information until consummation of the transactions contemplated
hereby, and, if such transactions shall not occur, the party receiving the
information or any of its affiliates or Representatives, as the case may be,
shall return to the party which furnished such information all documents or
other materials containing, reflecting or referring to such information, shall
keep confidential all such information for the period hereinafter referred to,
and shall not directly or indirectly at any time use such information for any
competitive or other commercial purpose; provided, however, that Buyer and its
affiliates shall be permitted to retain and share with their regulators,
examiners and auditors (only to the extent Buyer is required to disclose such
information, and, provided, that such parties are informed of the confidential
nature thereof and if appropriate directed to treat such information
confidentially) such materials, files and information relating to or
constituting Buyer's or any of its affiliates' or Representatives' work product,
presentations or evaluation materials as any such party deems reasonably
necessary or advisable in connection with auditing or examination purposes. The
obligation to keep such information confidential shall continue for two years
from the date this Agreement is terminated. In the event that either party or
any of its affiliates or Representatives is requested or required in the context
of a litigation, governmental, judicial or regulatory investigation or other
similar proceeding (by oral questions, interrogatories, requests for information
or documents, subpoenas, civil investigative demands or similar process) to
disclose any Confidential Information, the party or its affiliate or its
Representative so requested or required will directly or through the party or
such affiliate or Representative, if practicable and legally permitted, prior to
providing such information, provide the other party with notice of each such
request or requirement so that the other party may seek an appropriate
protective order or other remedy or, if appropriate, waive compliance with the
provisions of this Agreement. If, in the absence of a protective order or the
receipt of a waiver hereunder, the party or affiliate or Representative so
requested or required is, in the written opinion of its counsel, legally
required to disclose Confidential Information to any tribunal, governmental or
regulatory authority, or similar body, the party or affiliate or Representative
so required may disclose that portion of the Confidential Information which it
is advised in writing by such counsel it is legally required to so disclose to
such tribunal or authority or similar body without liability to the other party
hereto for such disclosure. The parties and their affiliates and Representatives
will exercise reasonable efforts, at the expense of the party who disclosed such
Confidential Information to the other party, to obtain assurance that
confidential treatment will be accorded the information so disclosed.

      As used in this Section 5.02(b), "Confidential Information" means all
data, reports, interpretations, forecasts and records (whether in written form,
electronically stored or otherwise) containing or otherwise reflecting
information concerning the disclosing party or its affiliates which is not
available to the general public and which the disclosing party or any affiliate
or any of their respective Representatives provides or has previously provided
to the receiving party or to the receiving party's affiliates or Representatives
at any time in connection with the transactions contemplated by this 
<PAGE>   24
Agreement, including but not limited to any information obtained by meeting with
Representatives of the disclosing party or its affiliates, together with
summaries, analyses, extracts, compilations, studies, personal notes or other
documents or records, whether prepared by the receiving party or others, which
contain or otherwise reflect such information. Notwithstanding the foregoing,
the following information will not constitute "Confidential Information": (i)
information that is or becomes generally available to the public other than as a
result of a disclosure by the receiving party or any affiliate or Representative
of the receiving party, (ii) information that the receiving party can
demonstrate was previously known to it or its affiliates or Representatives on a
nonconfidential basis prior to its disclosure by the disclosing party, its
affiliates or Representatives, (iii) information that became or becomes
available to the receiving party or any affiliate or Representative thereof on a
nonconfidential basis from a source other than the disclosing party or any
affiliate or Representatives of the disclosing party, provided that such source
is not known by the disclosing party or its affiliates or Representatives to be
subject to any confidentiality agreement or other legal restriction on
disclosing such information or (iv) information that the receiving party can
demonstrate has been independently acquired or developed by it or its affiliates
or Representatives without violating the obligations of this Section 5.02(b).

      5.03 No Solicitation. Unless and until this Agreement shall have been
properly terminated by either party pursuant to Section 8.01 hereof, neither
Seller nor the Seller Subsidiary shall (and Seller shall use its best efforts to
cause the Partners and Seller's officers, employees, representatives and agents,
including, but not limited to, investment bankers, attorneys and accountants,
not to), directly or indirectly, encourage, solicit, initiate or participate in
any discussions or negotiations with, or provide any information to, any
corporation, partnership, person or other entity or group (other than Buyer and
its affiliates or representatives) concerning any merger, tender offer, sale of
assets, sale of shares of partnership interests, capital stock or debt
securities or similar transaction involving Seller or the Seller Subsidiary (an
"Acquisition Transaction"). Seller will immediately communicate to Buyer the
terms of any proposal, discussion, negotiation or inquiry relating to an
Acquisition Transaction and the identity of the party making such proposal or
inquiry which it may receive in respect of any such transaction (which shall
mean that any such communication shall be delivered no less promptly than by
telephone within twenty-four (24) hours of Seller's receipt of any such proposal
or inquiry) or its receipt of any request for information from any governmental
agency or authority with respect to a proposed Acquisition Transaction.

      5.04 Consents. Each of Seller and Buyer will cooperate with the other and
use all reasonable efforts to, as promptly as practicable, prepare all
documentation, to effect all filings and to obtain all permits, consents,
approvals and authorizations of governmental agencies and authorities and
nongovernmental third parties, including but not limited to, consents of
Insurance Companies, which are necessary or appropriate to consummate the
transactions contemplated by this Agreement.

      5.05 Further Assurances. Subject to the terms and conditions herein
provided, each of the parties hereto agrees to use all reasonable efforts to, as
promptly as practicable, take, or cause to be taken, all 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. In case at any time after the Effective Time any
further action is necessary or desirable to carry out the purposes of this
Agreement, the proper officers and directors of Buyer and Seller shall use
reasonable efforts to take all such necessary action.

      5.06 Seller Disclosure Supplements. From time to time prior to the
Effective Time, and in any event on the date which is three (3) days prior to
the Closing Date, Seller will promptly supplement or amend the Seller Disclosure
Schedule with respect to any matter hereafter arising which, if existing,
occurring or known at the date of this Agreement, would have been required to be
set forth or described in the Seller Disclosure Schedule or which is necessary
to correct any information in the Seller Disclosure Schedule which has become
inaccurate. No supplement or amendment to the Seller Disclosure Schedules
pursuant to this Section 5.07 shall have any effect for the purpose of
determining Seller's satisfaction of any of the conditions set forth in Section
6.02 hereof.
<PAGE>   25
      5.07 Public Announcements. Except as otherwise required by law or the
rules of Nasdaq, Seller and Buyer will cooperate with each other in the
development and distribution of all news releases and other public information
disclosures with respect to this Agreement or any of the transactions
contemplated hereby.

      5.08 Post-Closing Governance. From the Effective Time and for a period of
at least two years thereafter, the Board of Directors of the Surviving Entity
shall consist of six (6) members, including, in addition to three (3)
individuals designated by Buyer (initially the three (3) persons who are serving
as directors of the Acquisition Subsidiary immediately prior to the Effective
Time), three (3) individuals designated by the Partners, who are either (a)
Partners or (b) other persons designated by the Partners and approved by Buyer
in its reasonable judgment prior to the Effective Time, each to hold office in
accordance with the certificate of formation and operating agreement of
Acquisition Subsidiary as then in effect.

      5.09 Acquisition Subsidiary. On or prior to the Closing Date, Buyer and
the Acquisition Subsidiary shall adopt an operating agreement which, in general,
shall provide for a Board of Directors which shall have the same power and
authority with respect to the Acquisition Subsidiary as may be exercised
pursuant to the Delaware Corporation Law by a board of directors of a
corporation incorporated in Delaware in the absence of any restriction on such
power and authority in the certificate of incorporation or bylaws of such
corporation. The operating agreement of the Acquisition Subsidiary shall also
contain standard indemnification and exculpation provisions for directors and
officers of the Acquisition Subsidiary, subject to applicable federal or state
laws and regulations governing Buyer or any of its Affiliates.

      5.10 Employment and Benefit Matters.

      (a) From and after the Effective Time, Buyer shall either continue in
effect the Seller Pension Plans, Seller Benefit Plans, and Seller Other Plans or
shall permit each Partner and Employee who remains employed by the Surviving
Entity to participate in substitute plans maintained by Buyer for its employees
provided that, (i) with respect to the pension plan maintained by Buyer for its
employees, such pension plan has benefits no less favorable in the aggregate
than the Seller Pension Plan, and (ii) with respect to such other plans of Buyer
other than Buyer's pension plan, such plans in the aggregate have benefits no
less favorable than the benefits currently provided under the Seller Benefit
Plans and Seller Other Plans. In the event that any Partner or Employee becomes
a participant in an employee benefit plan, program or arrangement maintained by
or contributed to by the Buyer or its affiliates (a "Transferred Employee"),
Buyer shall cause such plan, program or arrangement to treat the prior service
of such Transferred Employee with Seller or the Seller Subsidiary as service
rendered to Buyer or its affiliate, as the case may be, for purposes of
eligibility to participate, vesting and eligibility for special benefits under
such plan, program or arrangement of Buyer, but not for purposes of benefit
accrual (including minimum pension amount) or benefit payment, early retirement
subsidies, minimum pension benefits or post-retirement welfare benefits under
any pension benefit plan or welfare plan of Buyer extended to Employees or
Transferred Employees, and all preexisting conditions to which any such
Employees or Transferred Employees are subject shall be waived under the welfare
plans of the Buyer and its subsidiaries. Buyer agrees to provide Employees and
Transferred Employees with the types and levels of employee benefits maintained
by Buyer for similarly situated employees of the Buyer.

      (b) After the Effective Time, the Surviving Entity shall assume the
indemnification obligations to Partners currently set forth in the last
paragraph of Section 17 of the Partnership Agreement with respect to acts and
omissions taken prior to the Effective Time by such Partners, but only to the
extent permitted by federal and state law and regulations and excepting any
matter as to which Buyer is entitled to indemnification under Article IX hereof,
regardless of any limitation on indemnification set forth in Article IX hereof.
<PAGE>   26
      (c) All existing Non-Piracy Agreements executed and delivered by Seller
and Associates, Employees or other Persons, other than Partners, prior to the
Closing Date shall remain in full force and effect unchanged after the Closing
Date.

      5.11 Maintenance of Records. Through the Effective Time, Seller will
maintain the Records in the same manner and with the same care that the Records
have been maintained prior to the execution of this Agreement. Buyer may, at its
own expense, make such copies of and excerpts from the Records as it may deem
desirable. All Records, whether held by Buyer or Seller, shall be maintained for
such periods as are required by law, unless the parties shall, applicable law
permitting, agree in writing to a different period. From and after the Effective
Time, Buyer shall be solely responsible for continuing maintenance of such
Records.

      5.12 Leases. Seller shall consult with Buyer before renewing or extending
any material lease of an office or other material lease of Seller or the Seller
Subsidiary for real property or relating to furniture, fixtures or equipment
that is currently in effect but that would otherwise expire on or prior to the
Effective Time. Neither Seller nor the Seller Subsidiary shall cancel, terminate
or take other action that is likely to result in any cancellation or termination
of any such material lease without first consulting with Buyer. 

      5.13 Retired Partners. On or prior to the Closing Date, Seller shall
satisfy all obligations of Seller to Retired Partners and any other Person
described in Section 4.02(a)(i) of the Seller Disclosure Schedule under the
Partnership Agreement; provided, that Seller shall be permitted to satisfy all
obligations of Seller to Retired Partners or any other Person described in
Section 4.02(a)(i) of the Seller Disclosure Schedule under the Partnership
Agreement by directing Buyer to pay an applicable portion of the Purchase Price
to such Retired Partner or such other Person described in Section 4.02(a)(i) of
the Seller Disclosure Schedule on the Closing Date. Seller and the Partners
represent and warrant to Buyer that the payment of that portion of the Purchase
Price which Seller shall direct Buyer to pay to the Retired Partners and any
other Person described in Section 4.02(a)(i) of the Seller Disclosure Schedule
under the foregoing sentence, together with any other payments to be made as of
the Closing Date, shall satisfy all obligations of Seller and the Partners to
the Retired Partners and such other Persons described in Section 4.02(a)(i) of
the Seller Disclosure Schedule under the Partnership Agreement. On or prior to
the Closing Date, Seller and the Partners shall use their best efforts to obtain
a release from all Retired Partners and any other Person described in Section
4.02(a)(i) of the Seller Disclosure Schedule, in a form reasonably acceptable to
Buyer, pursuant to which each such Retired Partner or Person shall release
Seller and Buyer from any and all claims which such Retired Partner or Person
may have under the Partnership Agreement. 

      5.14 Obligations of Partners. On or prior to the Closing Date, all
obligations and indebtedness of the Partners to Seller under the Partnership
Agreement or otherwise, including without limitation, all obligations to make
capital contributions, shall have been repaid and satisfied in full, for which
purpose such Partners may direct Buyer to pay an applicable portion of the
Purchase Price to Seller, and no Partner shall thereafter have any remaining
obligation or liability to Seller outstanding as of the Closing Date.

      5.15 Deferred Service Revenue. At the Closing, immediately prior to the
Effective Time, Seller shall assign and transfer to the Acquisition Subsidiary,
cash, accounts receivables and/ or other assets of Seller having an aggregate
value equal to the amount of deferred service revenue (as described below) as of
such date (the "Deferred Service Assets"), in consideration for the agreement of
Acquisition Subsidiary to assume Seller's obligation to perform all of the
services with respect to which Seller has, in the ordinary course of business,
recorded "deferred service revenue" on its "Statements of Assets and Liabilities
and Partners' Accounts" as in effect on the Closing Date. Such assignment and
assumption shall be effective by the delivery (a) by Seller of a bill of sale
and such other instruments of assignment as Buyer shall reasonably request and
(b) by Acquisition Subsidiary of such instruments of assumption as Seller shall
reasonably request.

      5.16 Distribution of 1999 Partnership Income. Promptly after the Closing
Date, the Board of Directors of the Surviving Entity shall cause an accounting
to be made of Seller's partnership Income (as that term is defined in Section
5.01(e) hereof) for the period from January 1, 1999 through the Closing Date,
and shall provide prompt written notice to the Partners of such determination,
together with all 
<PAGE>   27
back-up materials used by the Surviving Entity in preparing the determination.
For purposes of this determination, "deferred service revenue" reflected in
Seller's Statements of Assets and Liabilities and Partners' Accounts shall be
included in income and the amount of cash and other assets assigned and
transferred to Acquisition Subsidiary pursuant to Section 5.15 shall be deducted
as an expense. The Partners shall have ten (10) days from delivery of the
written notice of determination pursuant to this Section 5.16 to object to such
determination; provided, that such objection shall be set forth in a written
notice signed by 70% in interest of the Partners (determined pursuant to
Schedule 1 hereto). In the event of such objection, the Partners and Seller
shall use reasonable efforts to resolve in good faith all of the Partners'
objections to the determination. In the event that, after the expiration of the
twenty (20) day period following delivery by the Partners of the written notice
of objection to Seller, the parties shall not have resolved the objection, such
objection shall be submitted to binding arbitration in Boston, Massachusetts
with each party sharing equally the costs of the arbitration. When the
determination becomes final (either because it is not so challenged or as a
result of the arbitrator's decision), the Surviving Entity shall distribute to
the Partners and the Retired Partners in accordance with instructions given by
the Partners hereunder, each Partner's and Retired Partner's proportionate share
of the difference between (i) the determination of partnership Income for the
period from January 1, 1999 until the Closing Date, minus (ii) distributions of
1999 Income prior to the Closing Date pursuant to Section 5.01(e)(ii) hereof.

      (f) Burdensome Condition. There shall not be any action taken, or any
statute, rule, regulation or order enacted, entered, enforced or deemed
applicable to the Merger or Buyer, by any federal or state governmental agency
or authority which, in connection with the granting of any Requisite Regulatory
Approval, imposes any condition or restriction upon Buyer, any Buyer subsidiary
or Seller after the Merger, which would so materially adversely impact the
economic or business benefits of the transactions contemplated by this Agreement
as to render inadvisable in the reasonable judgment of Buyer the consummation of
the Merger.

      (g) Legal Opinion. Buyer shall have received a legal opinion, dated the
Closing Date, of Palmer & Dodge LLP, counsel for Seller, containing the opinions
set forth in Exhibit B attached hereto, together with customary qualifications

under this Agreement shall be further subject to the satisfaction or waiver by
Seller, at or prior to the Effective Time, of the following conditions:

      (a) Absence of Material Adverse Changes. There shall not have occurred any
change in the assets, properties, liabilities, business, operations, results of
operations, financial condition or prospects of Buyer or any of its subsidiaries
which has had, or is reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect on Buyer.

      (b) Representations and Warranties; Performance of Obligations. The
obligations of Buyer required to be performed by it at or prior to the Closing
pursuant to the terms of this Agreement shall have been duly performed and
complied with in all material respects and the representations and warranties of
Buyer contained in this Agreement shall be true and correct in all material
respects as of the date of this Agreement and as of the Effective Time as though

which specifically relates to an earlier date) and Seller shall have received a
certificate to that effect signed by the vice chairman and chief financial
officer of Buyer or such other appropriate officer(s) of Buyer.

      (c) Third-Party Approvals. Any and all permits, consents, waivers,
clearances, approvals and authorizations of or notices to all nongovernmental
and nonregulatory third parties which are necessary in connection with the
consummation of the Merger and are required to be received, obtained or made by
Buyer shall have been so received, obtained or made and shall be in full force
and effect.

      (d) Legal Opinion. Seller shall have received a legal opinion dated the
Closing Date, of Eric R. Fischer, Executive Vice President, General Counsel and
Clerk to Buyer, and Bingham Dana LLP, counsel for Buyer and the Acquisition

Section 5.15 hereof.

      In addition to the foregoing, Buyer will furnish Seller with such
additional certificates, instruments or other documents in the name or on behalf
of Buyer, executed by appropriate officers or others, including without
limitation certificates or correspondence of governmental agencies or

the Effective Time in accordance with the following provisions:

      (a) by mutual written consent of Seller and Buyer authorized by their
Partners or Boards of Directors as the case may be;

      (b) by Seller or Buyer if the Effective Time shall not have occurred on or
prior to June 30, 1999 (the "Termination Date"); provided, however, that in the
event the delay is caused by Seller or due to Seller's failure to promptly
produce information required for any regulatory or governmental approval, as
required by Section 5.04 hereof, or Seller's failure to otherwise fulfill its
obligations to consummate the transactions, including the Merger, contemplated
hereby, the Termination Date shall be extended until September 30, 1999 or such
later date as shall have been agreed to in writing by Buyer and Seller;

      (c) by Buyer or Seller if any governmental or regulatory authority or
agency, or court of competent jurisdiction, shall have issued a final permanent
order or Injunction enjoining, denying approval of, or otherwise prohibiting the
consummation of the Merger and the time for appeal or petition for
reconsideration of such order or Injunction shall have expired without such
appeal or petition being granted; or

      (d) by the Buyer or the Seller (provided that the terminating party is not
then in material breach of any representation, warranty, covenant or other
agreement contained herein), in the event of a material breach by the other
party of any representation, warranty, covenant or other agreement contained
herein which breach is not cured after thirty (30) days written notice thereof
is given to the party committing such breach;

      (e) By the Board of Directors of Buyer or the Representatives of Seller
(provided that the terminating party is not then in breach of any representation
or warranty, covenant or other agreement contained in this Agreement) in the
event that any of the conditions precedent to the obligations of such party to
consummate the Merger cannot be satisfied or fulfilled by the date specified in
Section 8.01(b) of this Agreement.

      8.02 Effect of Termination. In the event of termination of this Agreement
by either Seller or Buyer as provided above, this Agreement shall forthwith
become null and void (other than Sections 5.02(b) and 10.02 hereof, which shall
remain in full force and effect) and there shall be no further liability on the
part of Seller or Buyer or their respective officers or directors to the other,
except (i) any liability of Seller or Buyer under said Sections 5.02(b) and
10.02, provided that, nothing contained herein shall relieve a party from
liability for any and all damages, costs and expenses, including all reasonable
attorneys' fees, sustained or incurred by the nonbreaching party caused by a
willful breach or default hereunder occurring prior to such termination.

      8.03 Amendment, Extension and Waiver. Subject to applicable law and as may
be authorized by the Boards of Directors of the Buyer and the Partners of
Seller, at any time prior to the consummation of the transactions contemplated
by this Agreement or termination of this Agreement in accordance with 
<PAGE>   31
the provisions of Section 8.01 hereof, Buyer and Seller 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 in Articles V and VI (other than Section 6.01) hereof. This
Agreement may not be amended except by an instrument in writing signed on behalf
of each of Buyer and Seller hereto. Any agreement on the part of Buyer or Seller
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.



ARTICLE IX

INDEMNIFICATION

      9.01 Claim Period; Survival. Any claim for a breach of any representation,
warranty, covenant or other agreement contained in or incorporated into this
Agreement referred to below must be made within the following periods:

            (a) with respect to the matters addressed in Sections 4.02(a) and
Section 5.13 hereof, [*];

            (b) with respect to the matters addressed in Section 4.10 hereof, 
[*]; and

            (c) with respect to all other representations, warranties, covenants
and agreements made by the Seller or the Partners contained in or incorporated
into this Agreement or in any certificate delivered pursuant hereto, [*] after
the later of (i) the Closing Date or (ii) with respect to any breach of
covenant, the date such covenant was required to be performed. The
representations, warranties, covenants and agreements of the Seller and the
Partners contained in or referred to in this Agreement or in any certificate
delivered pursuant hereto shall survive the Closing Date and continue for the
periods during which claims may be made as set forth above; provided, however,
that covenants of the Seller or Partners referred to in the proviso of Section
10.10 shall survive as stated therein.

      9.02 Terms of Indemnification. Subject to Section 9.05 below, the Partners
agree to indemnify, jointly and severally, Buyer (and its directors, officers,
agents and employees) against, and each of them agrees to protect, to defend and
to hold harmless the Buyer (and its directors, officers, agents and employees)
from all Damages (as such term is defined in Section 9.04 below) arising out of
or resulting from any inaccuracy in, or breach of, any of the representations,
warranties, covenants or other agreements of the Seller or the Partners
contained in or incorporated into this Agreement or in any certificate or
instrument delivered in connection herewith (with any representations,
warranties, covenants and other agreements of Seller being deemed to be of the
Partners for purposes of this indemnification), which inaccuracy or breach is
asserted and a claim for indemnification with respect thereto is made within the
applicable survival period set forth in Section 9.01 above. In addition, the
Partners agree that they will indemnify and hold Buyer and its Affiliates,
officers, directors and employees harmless from all Damages incurred by Buyer
resulting from, arising out of, or in connection with, any claim of a Retired
Partner or any other Person whether or not described in Section 4.02(a)(i) of
the Seller Disclosure Schedule with respect to unsatisfied obligations of Seller
to such Persons under the Partnership Agreement.

      9.03 Procedures. In any case under this Agreement where the Partners have
indemnified the Buyer against any claim or legal action, indemnification shall
be provided in accordance with the procedure outlined below:

      (a) Provided that prompt notice is given by the Buyer of a claim or suit
for which indemnification might be claimed, unless the failure to provide such
notice does not prejudice the interests 



*confidential treatment requested
<PAGE>   32
of the Partners, the Partners promptly will defend, contest, or otherwise
protect against any such claim or suit at their own cost and expense.

      (b) The Buyer may, but will not be obligated to, participate at its own
expense in a defense thereof by counsel of its own choosing, but the Partners
shall be entitled to control the defense unless the Buyer has relieved the
Partners from liability with respect to the particular matter, provided that the
Partners may only settle or compromise the matter subject to indemnification
without the consent of the Buyer if such settlement includes a complete release
of the Buyer as to the matters in dispute and provided further that Buyer will
not unreasonably withhold consent to any settlement or compromise that requires
its consent.

      (c) In the event the Partners fail to timely defend, contest, or otherwise
protect against any such claim or suit, the Buyer may, but will not be obligated
to, defend, contest, or otherwise protect against the same, and make any
compromise or settlement thereof and recover the entire costs thereof from the
Partners, jointly and severally, including reasonable attorneys' fees,
disbursements and all amounts paid as a result of such claim or suit or the
compromise or settlement thereof; provided, however, that if the Partners
undertake the defense of such matter, the Buyer shall not be entitled to recover
from the Partners for its costs incurred in the defense thereof other than the
reasonable costs of investigation undertaken by the Buyer and reasonable costs
of providing assistance.

      (d) The Buyer shall cooperate and provide such assistance as the Partners
may reasonably request in connection with the defense of the matter subject to
indemnification and in connection with recovering from any third parties amounts
that the Partners may pay or be required to pay by way of indemnification
hereunder. The Buyer shall be required to file a claim with its insurers as to
any matter subject to indemnification that is covered by insurance; provided,
however, that neither the filing of any such claim nor the insurer's rejection
thereof in whole or in part shall be a condition to the Partners' obligations
under this Article IX. The Buyer shall protect its position with respect to any
matter that may be the subject of indemnification hereunder in the same manner
as it would any similar matter where no indemnification is available.

      9.04 Damages. As used in this Article IX, the term "Damages" means any and
all losses, claims, damages, liabilities, obligations, judgments, settlements,
awards, demands, offsets, defenses, counterclaims, actions or proceedings,
reasonable out-of-pocket costs, expenses and attorneys' fees (including any such
reasonable costs, expenses and attorneys' fees incurred in enforcing a party's
right of indemnification against any indemnitor or with respect to any appeal)
and penalties and interest, if any, but shall not include any such amounts for
which the Buyer or Surviving Entity receives payment from a third party
(including insurers). Any insurance proceeds received by the Buyer with respect
to any matter that has been the subject of any prior indemnification payment(s)
by the Partners shall be promptly remitted to the Partners up to the aggregate
amount of such prior indemnification payment(s).

      9.05 Maximum Indemnification; Threshold; Caps; Exception.

      (a) The maximum liability of the Partners to Buyer under this Article IX
(except for claims with respect to the representations, warranties, covenants
and agreements set forth in Section 5.13 hereof, for which there shall be no
maximum liability) shall be [*] (the "Cap"); provided, however, that the maximum
liability of any individual Partner to Buyer under this Article IX (except for
claims with respect to the representations, warranties, covenants and agreements
set forth in Section 5.13 hereof for which there shall be no maximum liability)
shall be [*];

      (b) Buyer shall not be entitled to any indemnification with respect to
representations, warranties, covenants and agreements referred to in Section
9.01(c) of this Article IX (except for claims with respect to the
representations, warranties, covenants and agreements set forth in Section 5.13
hereof, for which there shall be no deductible) unless and only to the extent
that the aggregate Damages to the Buyer and its affiliates (without duplication)
exceed [*] (the "Aggregate Deductible") and provided further (i) for claims
and actions (except for claims and actions with respect to the representations,
warranties, covenants and agreements set forth in Section 5.13 hereof, for which
there shall be no limitation) arising within one year of the Closing Date, the
Partners shall be liable for the full amount by 



*confidential treatment requested
<PAGE>   33
which such Damages exceed the Aggregate Deductible up to the amount of the Cap,
(ii) for claims and actions (except for claims and actions with respect to the
representations, warranties, covenants and agreements set forth in Section 5.13
hereof, for which there shall be no limitation) [*] of the Closing Date, the
Partners shall be liable for the full amount by which such Damages exceed the
Aggregate Deductible but only up to the aggregate amount of [*] of the Cap, and
(iii) for claims and actions (except for claims and actions with respect to the
representations, warranties, covenants and agreements set forth in Section 5.13
hereof, for which there shall be no limitation) arising after [*] but within [*]
of the Closing Date, the Partners shall be liable for the full amount by which
such Damages exceed the Aggregate Deductible but only up to the aggregate amount
of [*] of the Cap, and

      (c) Notwithstanding any other provision of this Agreement, if the Damages
for which indemnification is sought arise out of an inaccuracy or breach which
was known to be inaccurate at the time made or deemed to be made or, with
respect to a breach of a covenant, was willful at the time performed or to be
performed, then there shall be no limitation on the amount of Damages that may
be recovered from the Partners hereunder.

      10.03 Parties in Interest. This Agreement shall be binding upon and shall

assigns and personal representatives; provided, however, that neither this

Plan of Merger, contains the entire agreement and understanding of the parties
with respect to its subject matter. Except as set forth in the Plan of Merger or

      10.9 Severability. In the event that any one or more provisions of this
Agreement shall for any reason be held invalid, illegal or unenforceable in any
respect, by any court of competent jurisdiction, such invalidity, illegality or

<PAGE>   35
the parties shall use their best efforts to substitute a valid, legal and
enforceable provision which, insofar as practicable, implements the purposes and
intents of this Agreement.

      10.10 Survival of Representations, Warranties and Covenants. Except as

party should institute an action or proceeding seeking specific enforcement of
the provisions hereof, each party against which such action or proceeding is
brought hereby waives the claim or defense that the party instituting such
action or proceeding has an adequate remedy at law and hereby agrees not to
assert in any such action or proceeding the claim or defense that such a remedy
at law exists.

      10.12 Partners' Representative. Each of the Partners hereby designates

Plan (the "Plan") which was amended and restated effective July 1, 1996 for the 
benefit of its eligible employees and their beneficiaries; and

WHEREAS, the Sponsoring Employer reserves the right to amend the Plan at any 
time in accordance with Section 17.1 of the Plan; and

WHEREAS, the Sponsoring Employer desires to amend the Plan to recognize a 
portion of the commissions earned by certain employees;

NOW THEREFORE, the Plan is hereby amended effective January 1, 1999 to add the 
following paragraph immediately after the first paragraph of Section 1.9:

     "Notwithstanding the foregoing, in the case of an Employee who is 
     specifically assigned to a formal commission-based incentive plan as
     either a
     a) Mortgage Originator,
     b) The Investment Group at USTrust sales representative, or
     c) UST Leasing Corp. sales representative.

     Compensation shall be no less than 80% of the sum of January 1 base rate of
     pay plus the commissions paid to such Employee by an Employer and included
     in the income reported on Federal Income Tax Form W-2 for the prior
     calendar year. "Commission-based incentive plans" are those that provide
     for variable payments directly related to the sale of company services and
     products, and provide for payment on a quarterly or more frequent basis." 

IN WITNESS WHEREOF, the Sponsoring Employer has caused this Amendment to be 
executed by its duly elected officer this 16th day of December, 1998.


                                             UST CORP.

      WHEREAS, UST Corp. (the "Sponsoring Employer") established the UST Corp.
Profit Sharing Plan & Trust (the "Plan") effective as of January 26, 1967,
amended from time to time thereafter and restated effective as of January 1,
1994 to comply with voluntary and statutory changes; and

      WHEREAS, the principal purposes of the Plan are to (a) set aside a portion
of the profits of the Sponsoring Employer and other participating Employers from
time to time for the distribution to, and the benefit of, Eligible Employees,
and (b) to facilitate systematic savings by Eligible Employees with funds for
their retirement or possible earlier needs; and, therefore, this Plan was
established as a profit sharing plan pursuant to Section 401(a) of the Internal
Revenue Code with a cash or deferred arrangement pursuant to Internal Revenue
Code Section 401(k); and

      WHEREAS, the Sponsoring Employer also established this Plan for the
exclusive benefit of its, and for the participating Employers', Eligible
Employees and their Beneficiaries and, except as permitted by law, neither the
principal nor the income of the Plan are to be paid to or reinvested in the
Sponsoring Employer or any other Employer or be used for any purpose other than
the exclusive benefit of their Eligible Employees and their Beneficiaries by
providing benefits as set forth herein, and by defraying reasonable expenses of
administering the Plan; and

      WHEREAS, the Sponsoring Employer desires to amend certain provisions of
the Plan and incorporate prior amendments; and

      NOW, THEREFORE, in consideration of the foregoing, the Plan is hereby
amended and restated as hereinafter set forth, effective July 1, 1996 unless
specifically stated otherwise. It is the intention of the Sponsoring Employer
that the Plan as herein amended and restated shall continue to be recognized as
a qualified profit sharing plan and trust under Sections 401(a) and 501(a) of
the Internal Revenue Code. It is further intended that the amended cash or
deferral arrangement forming part of the Plan shall continue to qualify under
Section 401(k) of the Internal Revenue Code. The provisions of the Plan as set
forth in this document shall apply only to an Eligible Employee who terminates
employment with the Sponsoring Employer or a participating Employer on or after
the effective date of a provision as set forth herein. The rights and benefits,
if any, of an Employee who terminated employment prior to the effective date of
a provision as set forth herein shall be determined in accordance with the
provisions of the Plan as in effect on the date his employment terminated.

        right to receive an allocation of Regular Profit Sharing Contributions,
        if any, and the right to make an in-service withdrawal or receive a Plan
        Loan.

        A Participant's election to resume making Before-Tax Contributions shall
        remain in effect while the Participant is an Eligible Employee or until
        such time as he files a new election on the appropriate form with the
        Benefits Committee. Any election to resume making Before-Tax
        Contributions shall be subject to the contribution limitations in effect
        under Sections 4.5, 12.4, and 12.5.

                                                                            (20)

        (a)    ROLLOVERS - An Eligible Employee may file a written request with
               the Benefits Committee to accept his Rollover Contribution. Any
               such request shall state the amount of the Rollover Contribution
               and include a statement that such contribution constitutes a
               Rollover Contribution.

               The Benefits Committee shall determine, in accordance with a
               uniform and nondiscriminatory policy, whether or not such
               contribution shall be accepted, and may require the Eligible
               Employee to submit such other evidence and documentation as the
               Benefits Committee determines necessary to ensure that the
               contribution qualifies as a Rollover Contribution.

               All Rollover Contributions must be made in cash.

               The amount paid to the Trust Fund in the form of a Rollover
               Contribution and any subsequent investment experience on such
               amount shall be credited to the Participant's Rollover Account.

        (b)    An Eligible Employee shall have at all times a nonforfeitable
               interest in 100% of his Rollover Contribution, and any investment
               experience on such amount.

        (c)    At the time the Rollover Contribution is made to the Trust Fund,
               the Eligible Employee must elect to have it invested in
               accordance with the terms of Section 6.2.

        (d)    An Eligible Employee who makes a Rollover Contribution to the
               Trust Fund shall be deemed to be a Participant with respect to
               such amount for all purposes of the Plan, except for purposes of
               Sections 2.1 through 2.5, Sections 4.1 through 4.3, Sections 5.1
               and 5.2, and Section 12.5.

        (e)    In no event shall any Rollover Contribution be subject to
               Employer Matching Contributions.

                                                                            (21)

4.5     MAXIMUM AMOUNT OF SALARY DEFERRAL AND CASH OPTION DEFERRAL

        (a)    On or after January 1, 1987, contributions made during a
               Participant's taxable year (which is presumed to be the calendar
               year) on behalf of the Participant under a Salary Deferral
               Agreement and Cash Option Deferral shall be limited to $7,000 (or
               such other limit as may be in effect at the beginning of such
               taxable year under Section 402(g)(1) of the Code), reduced by the
               amount of "elective deferrals" (as defined in Section 402(g)(3)
               of the Code) made during the taxable year of the Participant
               under any plans or agreements maintained by the Employer or an
               Affiliated Employer other than this Plan. Elective deferrals
               shall not include any elective deferrals returned to the Employee
               pursuant to Section 12.4(d).

        (b)    If contributions made on a Participant's behalf for the preceding
               taxable year of the Participant under a Salary Deferral
               Agreement, and Cash Option Deferral, and any other elective
               deferrals (within the meaning of Section 402(g)(3) of the Code)
               made on the Participant's behalf under any other qualified cash
               or deferred arrangement of the Employer or Affiliated Employer
               for such taxable year exceed $7,000 (or such other amount as
               adjusted in accordance with paragraph (a) above), the Participant
               shall notify the Benefits Committee in writing within two months
               following the close of such taxable year of the amount of such
               excess. Such notification shall include a statement that if such
               amounts are not distributed, the excess deferral amount, when
               added to amounts deferred under other plans or arrangements
               described in Section 401(k), 408(k), or 403(b) of the Code, will
               exceed the limit imposed on the Participant by Section 402(g) of
               the Code for the taxable year of the Participant in which the
               deferral occurred.

               If the elective deferral limit is exceeded for a Participant for
               a taxable year, the excess amount, adjusted (as described below)
               for allocable gains or losses for the taxable year with respect
               to which the deferral was made, shall be refunded to the
               Participant in a single payment no later than 3-1/2 months
               following the Participant's taxable year following the taxable
               year in which such excess deferral arose. If the Participant's
               Before-Tax Contribution Account and/or Cash Option Deferred
               Account is invested in more than one investment fund, such refund
               shall be made pro rata, to the extent practicable, from all such
               investment funds. The amount refunded shall not exceed the
               Participant's Before-Tax Contributions and Cash Option Deferrals
               under the Plan for the taxable year. If the foregoing refund is
               made, the payment shall be deemed to have been made before the
               close of the taxable year in which such excess deferral arose.

                                                                            (22)
<PAGE>   29
               Any Employer Matching Contributions made with respect to returned
               excess deferral amounts shall be forfeited.

               Excess deferrals shall be adjusted for allocable gains or losses
               for the taxable year in which the excess deferrals arose by
               multiplying the gains or losses credited to the Participant's
               Basic and Supplemental Before-Tax Contribution Accounts and Cash
               Option Deferred Account for that taxable year by a fraction, the
               numerator of which is the excess deferral amount made by the
               Participant for the taxable year, and the denominator of which is
               the sum of (i) the balance in the Participant's Basic and
               Supplemental Before-Tax Contribution Accounts and Cash Option
               Deferred Account as of the beginning of the taxable year, and
               (ii) the amount of Before-Tax Contributions and the Cash Option
               Share credited to the Participant's Basic and Supplemental
               Before-Tax Contribution Accounts and Cash Option Deferred Account
               for the taxable year.

               If the Participant fails to notify the Benefits Committee by the
               2-month period specified above, no refund will be made.

4.6     PARTICIPANT CONTRIBUTIONS FOR RETURNING VETERANS

        (a)    If a Participant incurs a Leave of Absence on account of
               Qualified Military Service and such Participant is reemployed by
               the Employer within the period during which his or her
               reemployment rights are protected by USERRA, upon reemployment
               such Participant shall be entitled to contribute to the Plan, in
               accordance with and subject to the limitations provided in
               Section 414(u) of the Code, the Before-Tax Contributions he or
               she would have been entitled to make had he or she remained
               actively employed by the Employer during such Leave of Absence.

        (b)    All such contributions must be made during the period which
               commences on the date of such a Participant's reemployment and
               has the same length as the lesser of (i) 3 multiplied by the
               period of such Participant's Qualified Military Service and (ii)
               five years. All such contributions will be invested in accordance
               with Section 6.2 and shall be credited with investment earnings
               (or losses) as provided in Section 6.7.

        (c)    For purposes of determining the amount of the Before Tax
               Contributions a Participant may contribute pursuant to paragraph
               (a) above, such Participant's Compensation during his or her
               Qualified Military Service shall be equal to: (i) the
               Compensation he

                                                                            (23)

               or she would have received during the period of Qualified
               Military Service based on the rate of pay he or she would have
               received but for the absence during the period of Qualified
               Military Service or (ii) if the Compensation he or she would have
               received during the period of Qualified Military Service is not
               reasonably certain, his or her average Compensation during the
               12-month period immediately before the Qualified Military Service
               or, if shorter, the period of employment immediately before the
               Qualified Military Service.

                                                                            (24)

        (a)    AMOUNT

               An Employer may make a profit sharing contribution to the Trust
               Fund, as of the end of each Plan Year, in such amount as is
               determined in the discretion of the Board prior to the date on
               which the contribution is required to be made.

               The Employer Profit Sharing Contribution shall consist of two
               parts as described below:

               (i)    REGULAR PROFIT SHARING CONTRIBUTION - The portion of the
                      Employer Profit Sharing Contribution equal to 66-2/3% of
                      the total Employer Profit Sharing Contribution.

               (ii)   CASH OPTION SHARE - The portion of the Employer Profit
                      Sharing Contribution equal to 33-1/3% of the total
                      Employer Profit Sharing Contribution.

        (b)    CASH OPTION

               (i)    CASH OPTION ELECTION
                      Within a reasonable time prior to the close of each Plan
                      Year, the Trustee shall deliver to each Participant a Cash
                      Option election form. Pursuant to such form, each
                      Participant may elect in writing by the end of the Plan
                      Year to receive in cash his Cash Option Share. Any
                      election under this Section shall be irrevocable for the
                      year in which such election is made.

                      If a Participant fails to make an election to either
                      receive an immediate cash payment of or to defer the Cash
                      Option Share under this Section, it shall be assumed that
                      he intended to receive his Cash Option Share in cash.

                                                                            (25)
<PAGE>   32
               (ii)   PAYMENT OF CASH OPTION SHARE
                      The Cash Option Share which a Participant elects to
                      receive in cash shall be paid to him as soon as
                      practicable after the year for which the election is made,
                      which generally shall be either February or March of such
                      following year; provided that in any event such payment
                      shall be made within any time limits prescribed by
                      applicable law.

        (c)    ALLOCATION OF EMPLOYER PROFIT SHARING CONTRIBUTIONS

               The Trustee shall make an allocation under this Section 5.1(c)
               and Section 7.5 to the Regular Profit Sharing Account and, if
               applicable, the Cash Option Deferred Account of each Participant
               who completed a Year of Service during, and is employed on the
               last day of, the Plan Year to which the Employer Profit Sharing
               Contribution relates. The Trustee shall allocate a portion of the
               current Employer Profit Sharing Contribution to each such
               Participant equal to a fraction as described below:

               (i)    The numerator shall be the Participant's Compensation for
                      the Plan Year,

               (ii)   The denominator shall be the total Compensation for all
                      Participants eligible to share in the contribution for the
                      Plan Year.

        (d)    ALLOCATION AMONG TOTAL ACCOUNT

               As of the last day of each Plan Year, the Trustee shall allocate
               to the Regular Profit Sharing Account and, if applicable, the
               Cash Option Deferred Account of each Participant entitled, in
               accordance with Section 5.1(c), to share in the Employer's Profit
               Sharing Contribution and forfeitures for such Plan Year, an
               amount (computed in dollars) equal to his proportionate share of
               the Employer's Profit Sharing Contribution and forfeitures for
               such Plan Year, as set forth in Sections 5.1(c) and 7.5,
               respectively. Except as provided in Section 5.1(b), one third of
               the Employer's Profit Sharing Contribution made on behalf of a
               Participant shall be credited to the Participant's Cash Option
               Deferred Account. The remaining portion of the Employer's Profit
               Sharing Contribution, together with the Participant's share of
               forfeitures, shall be allocated to the Participant's Regular
               Profit Sharing Account.

        (e)    RESPONSIBILITY OF COMMITTEE AND TRUSTEE

                                                                            (26)
<PAGE>   33
               If no contribution under this Section shall be made for any year,
               the Employer shall so advise the Benefits Committee and the
               Trustee. Neither the Trustee nor the Benefits Committee shall be
               under any duty to inquire into the correctness of the amounts
               contributed and paid over to the Trustee hereunder or to
               determine whether any contribution is payable under this Section
               5.1 or to enforce payment of any contribution by the Employer.

        (f)    ADVANCE CONTRIBUTIONS

               The Employer, at any time, may make payments on account of its
               contribution for the year. Such payment shall constitute a part
               of the Trust Fund upon receipt by the Trustee but may be
               segregated in an Advance Contribution Account which shall be held
               in cash or such other property as may be permissible under
               applicable law. The total market value of such Advance
               Contribution Account on the last day of the Plan Year, together
               with any other contribution by the Employer, shall be allocated
               as provided in Section 5.1(c).

5.2     EMPLOYER MATCHING CONTRIBUTIONS

        As of each Valuation Date, an Employer Matching Contribution shall be
        credited to the Employer Matching Contribution Account of each
        Participant who made Basic Before-Tax Contributions to the Trust Fund
        since the previous Valuation Date and who is employed by the Employer on
        said Valuation Date. The Employer Matching Contributions made on behalf
        of each such Participant shall be based upon the Participant's Basic
        Before-Tax Contributions and Compensation since the previous Valuation
        Date, and shall be equal to the sum of (a) 100% of the Participant's
        Basic Before-Tax Contributions which do not exceed 1% (2% effective
        January 1, 1997) of Compensation, plus (b) 25% of the Participant's
        Basic Before-Tax Contributions which exceed 1% (2% effective January 1,
        1997) of Compensation.

        No Employer Matching Contributions shall be made with respect to
        Supplemental Before-Tax Contributions or Cash Option Deferrals made by
        or on behalf of any Participant.

                                                                            (27)
<PAGE>   34
5.3     FORM AND TIMING OF EMPLOYER CONTRIBUTIONS

        Employer Contributions for each fiscal year shall be made by the
        Employer within the period required by the provisions of the Code
        applicable to such year. The Employer's Contribution for each year may
        be paid to the Trustee either in cash or other property, to the extent
        permissible under law; provided that any securities so contributed shall
        be valued at fair market value on the date of the contribution pursuant
        to the valuation methods set forth in Section 6.6.

5.4     EMPLOYER MATCHING CONTRIBUTIONS

        If a Participant incurs a Leave of Absence on account of Qualified
        Military Service and such Participant is reemployed by the Employer
        within the period during which his or her reemployment rights are
        protected by USERRA, Employer Matching Contributions which would have
        been credited to the Employer Matching Contribution Account had such
        former Participant remained actively employed by the Employer during
        such Leave of Absence shall be made to the extent provided in and in
        accordance with Section 414(u) of the Code; and Employer Profit Sharing
        Contributions which would have been credited to the Employer Profit
        Sharing Contribution Account had such former Participant remained
        actively employed by the Employer during such Leave of Absence shall be
        made in accordance with Section 414(u) of the Code.

                                                                            (28)

        Sponsoring Employer may from time to time direct. The Sponsoring
        Employer may direct that each investment fund be invested:

        (a)    At the discretion of the Trustee in accordance with such
               investment guidelines and objectives as may be established by the
               Sponsoring Employer for such investment fund; or

        (b)    At the discretion of a duly appointed Investment Manager in

        (c)    In such investments as the Sponsoring Employer may specify for
               such investment fund.

        The Sponsoring Employer may from time to time change its direction with

        investment fund or establish additional funds. Whenever an investment
        fund is eliminated, the Trustee shall promptly liquidate the assets of
        such investment fund and reinvest the proceeds thereof in accordance
        with the directions of the Sponsoring Employer.

        The Trustee may maintain from time to time reasonable amounts in cash or
        cash equivalents in any fund. All expenses properly attributable to an
        investment fund, including but not limited to brokerage fees and stock
        transfer taxes, shall be paid from such investment fund, unless paid by
        the Employer.

        All dividends, interest and other income of each investment fund, as
        well as stock splits, stock dividends, and the like, shall be reinvested
        in that investment fund.

                                                                            (29)

6.2     INVESTMENT ELECTION

        (a)    The Plan permits Participants or Beneficiaries to exercise
               control over the assets in his Total Account in a manner which is
               intended to bring the Plan within the rule of Section 404(c) of
               the Employee Retirement Income Security Act of 1974. By allowing
               Participants and Beneficiaries to elect among several investment
               funds, the Employer intends that fiduciaries of the Plan be
               relieved of fiduciary responsibility for any loss, or by reason
               of any breach, which results from the Participant's or
               Beneficiary's exercise of control.

               The Participant's Total Account shall be invested in one or a
               combination of the available investment alternatives established
               and maintained by the Trustee. These alternatives may include,
               but are not limited to: an Equity Fund, seeking growth of capital
               by investing in a wide range of companies, a Stable Asset Fund,
               consisting primarily of FDIC-insured deposits, and a Balanced
               Fund, investing in both stocks and fixed-income securities. The
               Employer and/or Trustee reserves the right to add to or change
               the types of investment alternatives available to Participants
               and Beneficiaries.

               At the time an Eligible Employee becomes a Participant in the
               Plan and makes an election in accordance with Section 4.1, the
               Eligible Employee must choose, on a form provided by the Benefits
               Committee, the percentage in which contributions made by or on
               behalf of such Participant are to be invested in each investment
               fund. Such percentage may be 0%, or in increments of 5%, up to a
               total of 100%. Participant's investment elections must total
               100%. A Participant or Beneficiary may elect to have all of his
               Total Account invested in a single investment vehicle.

        (b)    During the absence of a valid election by a Participant, the
               contributions made by or on behalf of such Participant, shall be
               credited to the fund with the least investment risk.

6.3     CHANGE IN INVESTMENT ELECTION

        A Participant may elect, effective as of any Change Date, to reallocate
        in 5% increments his Basic and Supplemental Before-Tax Contribution
        Accounts, Employer Matching Contribution Account, and Rollover Account
        among the investment funds, provided that the Participant files with the
        Benefits Committee a new election on the appropriate form at such time
        and in such manner as the Benefits Committee may require. Any elections
        made in accordance with this paragraph shall apply to the amounts
        existing in the Participant's Basic

                                                                            (30)
<PAGE>   37
        and Supplemental Before-Tax Contribution Accounts, Employer Matching
        Contribution Account, and Rollover Account on the Change Date and to all
        contributions credited to such Accounts on or after such Change Date.

        The Benefits Committee may from time to time:

        (a)    Limit or restrict a Participant's ability to change the
               allocation of his Basic and Supplemental Before-Tax Contribution
               Accounts, Employer Matching Contribution Account, and Rollover
               Account among the investment funds and/or withdraw balances from
               the various investment funds in order to conform to the
               practices, provisions, or restrictions of any investment media
               held in any such investment fund; and

        (b)    Adopt procedures relating to the determination and allocation of
               the investment earnings among the Participants' Basic and
               Supplemental Before-Tax Contribution Account, Employer Matching
               Contribution Account, and Rollover Account, in order to
               facilitate the administration of the Plan on an equitable and
               practicable basis.

6.4     RESPONSIBILITY OF PARTICIPANT IN SELECTING INVESTMENT FUNDS

        The selection of an investment fund or funds is the sole responsibility
        of each Participant. The Benefits Committee, the Trustee, the Investment
        Manager, the Employer, or any other fiduciary to the Plan may not advise
        a Participant as to the election of any investment fund or the manner in
        which contributions shall be invested. The fact that a security is
        available to Participants for investment under the Plan shall not be
        construed as a recommendation as to the purchase of that security, nor
        shall the designation of an investment fund impose any liability on the
        Benefits Committee, the Trustee, the Investment Manager, or the
        Employer.

6.5     ESTABLISHMENT OF PARTICIPANT ACCOUNTS

        (a)    The Trustee shall establish and maintain for each Participant a
               Total Account, consisting of the following accounts, and any such
               other accounts as may be deemed necessary by the Benefits
               Committee:

               (i)     Basic Before-Tax Contribution Account; 
               (ii)    Supplemental Before-Tax Contribution Account; 
               (iii)   Employer Matching Contribution Account; 
               (iv)    Regular Profit Sharing Account;

                                                                            (31)
<PAGE>   38
               (v)     Cash Option Deferred Account; and 
               (vi)    Rollover Account.

        (b)    Within each of the accounts described in paragraph (a) above,
               separate records shall be kept of the portion of the account
               credited to each investment fund.

        (c)    Such accounts as described in Sections 6.5(a)(iv) and (v) above
               shall be maintained primarily for bookkeeping purposes. The
               Trustee shall not be required to segregate the assets in these
               accounts of Participants for purposes of investment or otherwise.

6.6     FAIR MARKET VALUE OF TRUST ASSETS

        The fair market value of all of the assets of the Trust Fund shall be
        determined by the Trustee on each Valuation Date.

6.7     ALLOCATION OF TRUST ASSETS

        The balance of each Participant's Total Account (including the Regular
        Profit Sharing Account portion, if any, of a Forfeiture Account
        attributable to a Participant and not yet available for reallocation
        pursuant to Section 7.5) shall be adjusted as of each Valuation Date.

        In addition to the rules set forth above, the credit balance of the
        Total Accounts of Participants shall be reduced by any distributions
        made since the most recent Valuation Date.

6.8     CORRECTION OF ERROR

        The Benefits Committee may adjust the Total Accounts of any or all
        Participants or Beneficiaries in order to correct errors or rectify
        omissions, including, without limitation, any allocations to a
        Participant's Total Account made in excess of the limits specified in
        Sections 4.5, 12.4, and 12.5, in such manner as it believes will best
        result in the equitable and nondiscriminatory administration of the
        Plan.

                                                                            (32)
<PAGE>   39
6.9     ALLOCATION SHALL NOT VEST TITLE

        The fact that an allocation is made and amounts are credited to the
        Total Account of a Participant shall not vest in such Participant any
        right, title, or interest in and to any assets except at the time or
        times and upon the terms and conditions expressly set forth in this
        Plan, nor shall the Trustee be required to segregate physically the
        assets of the Trust Fund by reason thereof.

                                                                            (33)

                                    BENEFITS


7.1     NATURE OF BENEFITS

        The benefits provided by this Plan consist of the right of a Participant
        to receive a distribution of the vested portion of his Total Account in
        accordance with the provisions of this Article 7. The value of a
        Participant's Total Account shall be determined as of the Valuation Date
        preceding the date on which payment is made.

7.2     MEDIUM AND METHOD OF DISTRIBUTION

        The amount payable to a Participant (or Beneficiary) under the terms of
        the Plan shall be distributed in the form of a single lump sum payment
        in cash.

7.3     TIMING OF DISTRIBUTION

        Except as noted below and otherwise provided in this Plan, the vested
        portion of a Participant's Account shall be paid as soon as
        administratively feasible following the first Valuation Date following
        the date the Employee's employment with the Employer or an Affiliated
        Employer terminates. Distribution shall be made no later than 60 days
        after the close of the Plan Year in which occurs the latest of the
        Participant's (A) Normal Retirement Date, (B) tenth anniversary of Plan
        participation, or (C) separation from service with the Employer and all
        Affiliated Employers.

        If the value of a Participant's vested Account has ever exceeded $3,500
        during his participation in the Plan, payment to such Participant shall
        not be made in accordance with the above unless the Participant consents
        to such distribution. In addition, a Participant who elects not to
        receive his distribution in accordance with the above, may elect to
        receive such distribution at any time prior to the date distributions
        must commence in accordance with IRC Section 401(a)(9).

                                                                            (34)
<PAGE>   41
7.4     VESTING

        A Participant shall always have a nonforfeitable, or 100% vested,
        interest in his Basic and Supplemental Before-Tax Contribution Accounts,
        Cash Option Deferred Account, Employer Matching Contribution Account,
        and Rollover Account. A Participant's vested interest in his Regular
        Profit Sharing Account shall become 100% vested, upon the earliest of
        his:

        (a)    Normal Retirement Date, 
        (b)    death (while actively employed), 
        (c)    Disability Retirement Date, or 
        (d)    September 30, 1995.

        The vested interest of a Participant in his Regular Profit Sharing
        Account at any time prior to the date indicated above, shall be based
        upon the Participant's Years of Service in accordance with the
        following:

<TABLE>
<CAPTION>
             YEARS OF SERVICE                           VESTED PERCENTAGE

                     4                                          40%

                     6                                          80%
                 7 or more                                      100%
</TABLE>

        If any Plan amendment changes the vesting schedule set forth above, each
        Participant who has completed at least three Years of Service as of the
        later of (a) the date the Plan amendment is adopted, or (b) the date the
        Plan amendment becomes effective shall have the vested percentage of his
        Regular Profit Sharing Account computed in accordance with the vesting
        schedule that produces the higher vested benefit.

7.5     FORFEITURES

        (a)    Prior to January 1, 1985:

               If a Participant incurs a One-Year Break in Service before his
               Regular Profit Sharing Account had become 100% vested pursuant to
               the provisions of the Plan in effect on his date of termination,
               the nonvested portion of such Account shall be forfeited
               effective as of the last day of the Plan Year during which the
               Participant incurred a 

                                                                            (35)
<PAGE>   42
               One-Year Break in Service. Upon such date, the amount forfeited
               shall be added to the Employer Profit Sharing Contribution for
               the Plan Year ending on such date and shall be allocated in the
               same manner as such Employer Profit Sharing Contribution.

        (b)    After January 1, 1985:

                  (i)   Timing of Forfeitures:

                        If a Participant who terminates his employment with the
                        Employer before his Regular Profit Sharing Account had
                        become 100% vested and receives a distribution of the
                        vested portion of his Regular Profit Sharing Account,
                        the non-vested amount remaining in such Participant's
                        Regular Profit Sharing Account, after distribution of
                        the vested portion of his Regular Profit Sharing
                        Account, shall be forfeited as of the last day of the
                        Plan Year in which his termination of employment from
                        the Employer occurs and has received the vested portion
                        of his Regular Profit Sharing Account. If a Participant
                        who terminates employment before his Regular Profit
                        Sharing Account had become 100% vested does not receive
                        a distribution of the vested portion of his Regular
                        Profit Sharing Account, the non-vested amount in such
                        Participant's Regular Profit Sharing Account shall be
                        forfeited on the last day of the Plan Year during which
                        the Participant incurs five consecutive One Year Breaks
                        in Service. Solely for purposes of this paragraph, a
                        Participant who terminates on the last day of a Plan
                        Year shall be treated as though he terminated employment
                        on the first day of the following Plan Year. The amount
                        forfeited shall be allocated in the same manner as the
                        Regular Profit Sharing Contribution for such year.


                 (ii)   Rehire - Repayments Permitted Within Five Years of
                        Reemployment:

                        In the event a Participant described in subparagraph (i)
                        above is rehired prior to incurring five consecutive
                        One-Year Breaks in Service, the Participant shall be
                        permitted to repay the entire amount of the distribution
                        in order to restore the nonvested portion of his Regular
                        Profit Sharing Account balance to his Total Account for
                        the purpose of future vesting as if he had not separated
                        from Service or received a distribution. The permissible
                        repayment period shall continue until the fifth
                        anniversary of the day on which the Employee is
                        reemployed by the Employer.

                                                                            (36)
<PAGE>   43
                        If such repayment is not made before such period, such
                        Participant's vested amount will be determined by
                        including Years of Service accrued before such
                        Participant's separation from Service but without regard
                        to amounts allocated prior to such separation.

                        In the event that the terminated Participant's vested
                        balance in his Regular Profit Sharing Account was zero,

                        (A)   distribution of the vested balance in his Regular
                              Profit Sharing Account shall be deemed to have
                              been made to him as of the date of his termination
                              of employment,

                        (B)   repayment shall be deemed to be made on his
                              reemployment commencement date, and

                        (C)   the balance in his Regular Profit Sharing Account
                              shall be restored accordingly.

                (iii)   Restoration of Regular Profit Sharing Account Balances:

                        A Participant who made or who is deemed to have made a
                        repayment pursuant to subparagraph (ii) above will have
                        recredited to his Regular Profit Sharing Account, as of
                        the last day of the Plan Year coinciding with or next
                        following his date of rehire, the portion of such
                        Account balance which he forfeited upon his prior
                        termination from Service with the Employer unadjusted
                        for any subsequent gains or losses. The sources for
                        restoring a previous forfeiture in a subsequent year
                        will be, in order of priority:

                        (A)   Forfeitures occurring in the Plan Year in which
                              the Regular Profit Sharing Account balances are
                              recreated, if not sufficient then;

                        (B)   Earnings allocable to nonsegregated Regular Profit
                              Sharing Account balances and realized during the
                              Plan Year in which such Account balances are
                              recreated, if still not sufficient then;

                                                                            (37)

                        (C)   Employer Profit Sharing Contributions made by the
                              Employer for the Plan Year in which the Regular
                              Profit Sharing Account balances are recreated.

                        Such reinstated Regular Profit Sharing Account balances
                        shall be subject to the vesting requirements described
                        in Article 7.4.

                 (iv)   Rehire After Five Years:

                        In the event a former Participant is rehired after
                        incurring five consecutive One-Year Breaks in Service,
                        the portion of the Participant's Regular Profit Sharing
                        Account which he forfeited upon his prior termination
                        shall be deemed to be a permanent forfeiture and shall
                        not be recredited to the Participant's Regular Profit
                        Sharing Account if he subsequently becomes eligible to
                        participate in the Plan, except as follows:

                        Such a former participant shall have his prior nonvested
                        portion in his Regular Profit Sharing Account restored,
                        if such former Participant repays the entire amount of
                        the distribution he previously received under the Plan
                        (upon his prior termination) by the close of five
                        consecutive One-Year Breaks in Service commencing after
                        such prior distribution.

                        To the extent applicable, the procedures of paragraph
                        (iii) above shall apply to the restoration of the
                        Participant's nonvested portion of his Regular Profit
                        Sharing Account if he repays his prior distribution
                        under this paragraph (iv).

7.6     PERMANENT AND TOTAL DISABILITY

        "PERMANENT AND TOTAL DISABILITY" shall be a total disability which
        satisfies the requirements for benefit entitlement under any long-term
        disability plan or program sponsored by the Employer and the Benefits
        Committee concludes that such total disability is likely to be
        permanent.

        If any disabled Participant returns to the employ of the Employer, he
        shall become a Participant on his reemployment date, and the various
        Plan sections regarding reemployment with an Employer shall be applied
        to him.

                                                                            (38)

7.7     DISTRIBUTION ON DEATH

        Upon the death of any Participant, the vested portion of the
        Participant's Total Account shall be distributed to the Participant's
        designated Beneficiary in accordance with the following rules:

        (a)    If the Participant has a Spouse at his date of death, the
               distribution shall be paid to his Spouse as designated
               Beneficiary. The distribution may be paid to a designated
               Beneficiary other than the Participant's Spouse while the Spouse
               is living only with the written consent of the Participant's
               Spouse. A spousal consent must:

                  (i)   Be in writing on a form provided by the Benefits
                        Committee;

                  (ii)  Specify the Beneficiary;

                  (iii) Acknowledge the effect of such consent; and

                  (iv)  Be witnessed by a notary public.

               Any such consent will be valid only with respect to the Spouse
               who signs the consent. A spousal consent is not required,
               however, if the Participant establishes to the satisfaction of
               the Benefits Committee

                        (A)   that there is no Spouse; 
                        (B)   that the Spouse cannot be located;
                        (C)   that the Participant has been abandoned by the
                              Spouse within the meaning prescribed by applicable
                              law and evidenced by a court order; or
                        (D)   that spousal consent is not required under other
                              applicable regulations.

               If the Participant does not have a Spouse at his date of death,
               the distribution shall be paid to the designated Beneficiary
               elected by the Participant.

               If a Participant's designated Beneficiary shall have predeceased
               the Participant, or if a Beneficiary designation shall have
               lapsed or failed for any reason, payment will be made to the
               Beneficiary designated under Section 7.10.

                                                                            (39)
<PAGE>   46
        (b)    The distribution shall be paid to the Beneficiary as soon as
               administratively feasible following the Valuation Date after the
               date the Participant's death is reported to the Benefits
               Committee; provided the designated Beneficiary has filed a proper
               distribution election form with the Benefits Committee.
               Distribution shall be made in a single lump sum cash payment.

        (c)    If the Participant's designated Beneficiary is his Spouse, such
               Spouse may elect to defer distribution until any time prior to
               the date distributions must commence in accordance with IRC
               Section 401(a)(9). Such election must be made no later than the
               date distribution is required under paragraph (b) above. If the
               Participant's Spouse dies before any distribution is made, the
               provisions of this Section shall be applied as though the Spouse
               were the Participant.

        (d)    Notwithstanding the preceding, if the Participant's Account to
               which the Beneficiary is entitled under this Section did not, at
               any time, exceed $3,500 during the Participant's participation in
               the Plan, distribution shall be made to the Beneficiary in a
               single lump sum cash payment as soon as practicable after the
               Valuation Date next following the date the Participant's death is
               reported to the Benefits Committee.

7.8     DISTRIBUTION TO ALTERNATE PAYEES

        The Benefits Committee may authorize the Trustee to make a lump sum
        distribution to an Alternate Payee pursuant to a Qualified Domestic
        Relations Order as soon as administratively practicable after the
        Valuation Date next following the date the Alternate Payee has filed a
        request for distribution with the Committee.

        If the Alternate Payee's nonforfeitable interest in the Plan does not
        exceed $3,500, distribution to the Alternate Payee shall be made as soon
        as administratively possible.

7.9     INVESTMENT OF DEFERRED DISTRIBUTIONS

        Any amounts deferred in accordance with this Article 7 shall be held in
        the Participant's Total Account and shall continue to share in the
        investment experience of the Trust Fund as long as a balance remains.

7.10    DESIGNATION OF BENEFICIARY

                                                                            (40)
<PAGE>   47
        (a)    Each Participant may designate, on a form provided by the
               Benefits Committee, a Beneficiary or Beneficiaries to receive any
               benefits distributable hereunder after the death of the
               Participant. Such designation of a Beneficiary or Beneficiaries
               shall not be effective for any purpose unless and until it has
               been filed by the Participant with the Benefits Committee,
               provided, however, that a designation mailed by the Participant
               to the Benefits Committee prior to his death and received by the
               Benefits Committee after his death shall take effect upon such
               receipt, but prospectively only and without prejudice to any
               payor or payee on account of any payments made before receipt of
               such designation by the Benefits Committee.

               Notwithstanding the above, the following provisions shall apply:

                  (i)   A Participant's Beneficiary shall be his surviving
                        Spouse, if the Participant has a surviving Spouse,
                        unless the Participant has designated another
                        Beneficiary pursuant to the spousal consent requirements
                        of Section 7.7(a).

                 (ii)   A Participant may from time to time change his
                        designated Beneficiary or Beneficiaries, but any such
                        designation which has the effect of naming a person
                        other than the Participant's surviving Spouse, if any,
                        as sole Beneficiary is subject to the spousal consent
                        requirements of Section 7.7(a).

        (b)    In the absence of a Beneficiary designation by the deceased
               Participant, or if a designation of Beneficiary lapses or fails
               for any reason, distribution of the deceased Participant's
               nonforfeitable interest in the Trust Fund shall be distributed to
               the surviving Spouse of the Participant or, if there be none
               surviving, to the duly appointed and currently acting personal
               representative of the Participant's estate.


7.11    ADVICE OF BENEFITS

        The Benefits Committee shall establish such rules and procedures as it
        deems necessary to properly advise all Participants and other persons as
        to any rights they may have to a benefit under this Plan and may impose
        upon any such person reasonable requirements with respect to filing
        application for such benefits.

7.12    INCAPACITY

                                                                            (41)
<PAGE>   48
        If any person to whom a benefit is payable hereunder is an infant or if
        the Benefits Committee determines that any person to whom such benefit
        is payable is incompetent by reason of physical or mental disability,
        the Benefits Committee may cause the payments becoming due to such
        person to be made to such person's legally appointed guardian or
        conservator.

7.13    PROOF OF CLAIM

        The Benefits Committee may require such proof of death and such evidence
        of the right of any person to receive payment of the value of the vested
        interest in the Trust Fund of a deceased Participant or former
        Participant as the Benefits Committee may deem desirable.

7.14    DIRECT ROLLOVER DISTRIBUTIONS

        Notwithstanding any provision of the Plan to the contrary, if any
        distribution to a Distributee (i) is made on or after January 1, 1993,
        (ii) totals $200 or more, and (iii) constitutes an Eligible Rollover
        Distribution, the Distributee may elect on a form provided by the
        Benefits Committee to have all or part of such Eligible Rollover
        Distribution paid in a direct rollover to an Eligible Retirement Plan
        selected by the Distributee. For this purpose, a Distributee, an
        Eligible Rollover Distribution, and an Eligible Retirement Plan shall be
        defined as follows:

        (a)    Distributee includes an Employee or former Employee. In addition,
               the Employee's or former Employee's surviving spouse and the

               the alternate payee under a qualified domestic relations order,
               as defined in Section 414(p) of the Code, are Distributees with
               regard to the interest of the spouse or former spouse.

        (b)    Eligible Rollover Distribution means any distribution of all or
               any portion of the balance to the credit of a Distributee, except
               that an Eligible Rollover Distribution does not include any
               distribution that is one of a series of substantially equal
               periodic payments (not less frequently than annually) made for
               the life (or life expectancy) of the Distributee or the joint
               lives (or joint life expectancies) of the Distributee and the
               Distributee's designated beneficiary, or for a specified period
               of ten years or more; any distribution to the extent such
               distribution is required under Section 401(a)(9) of the Code; and
               the portion of any distribution that is not includable in gross
               income (determined without regard to the exclusion for net
               unrealized appreciation with respect to employer securities).

                                                                            (42)

                  (ii)  an individual retirement annuity (other than an
                        endowment contract) described in Section 408(b) of the
                        Code;

                  (iii) with respect to Participants and Distributees who are
                        alternate payees only, a qualified defined contribution
                        plan and exempt trust described in Sections 401(a) and
                        501(a) of the Code respectively, the terms of which
                        permit the acceptance of rollover contributions; or

                  (iv)  with respect to Participants and Distributees who are
                        alternate payees only, an annuity plan described in
                        Section 403(a) of the Code.

        If an election is made to have only a part of an eligible rollover
        distribution paid in a direct rollover, the amount of the direct

        the Code and the Regulations prescribed thereunder are hereby

        (g)    Repayment by Participants actively employed by an Employer during
               the repayment period shall be in equal installments by weekly or
               bi-monthly payroll deductions and 

                                                                            (45)

               Participant in the month following receipt of the Loan.

        (h)    Full repayment of the entire outstanding balance of a Loan may be
               as of the last day of any month during the repayment period.

        (i)    If any individual fails to repay a Plan Loan in accordance with
               its terms, the Loan shall be in default. The balance will be paid
               automatically from the applicant's Total Account (unless he
               repays the Loan prior to the last day of the month in which he
               terminates) in the following order until the full amount of the
               Loan has been provided:

                  (i)   from his Supplemental Before-Tax Contribution Account;

                  (ii)  from his Basic Before-Tax Contribution Account;

                  (vi)  from his Regular Profit Sharing Account (to the extent
                        vested).

               If the Loan remains in default at the time the applicant
               terminates employment, in accordance with governmental
               regulations, the Benefits Committee shall authorize the Trustee
               to cancel and distribute the promissory note and report a taxable
               distribution to the Internal Revenue Service equal to the amount
               transferred from his Total Account to repay the loan.

8.3     LOAN FUND

        A separate loan fund shall not be established; instead, Participant
        loans shall be considered an asset of the investment fund which contains
        the least investment risk or such other fund selected by the Trustee.

                                                                            (46)

8.4     LOANS TO PARTIES-IN-INTEREST

        (a)    Notwithstanding anything to the contrary in the Plan, Plan Loans
               shall be made available to Participants (either active or former)
               and Beneficiaries who are "parties-in-interest" as defined in
               Section 3(14) of ERISA, to the extent required by applicable law.

        (b)    The provisions of this Section 8.4 shall be null and void without
               amendment to the Plan in the event that by ruling of the
               Commissioner of Internal Revenue and/or the Secretary of Labor
               the rules herein set forth are no longer necessary to prevent any
               prohibited discrimination that may occur in the Plan's Loan
               program.

8.5     IN SERVICE WITHDRAWALS AFTER AGE 59-1/2

        A Participant who has attained age 59-1/2 and completed ten or more
        Years of Service may elect to withdraw all or any part of the vested
        portion of his Total Account, by submitting a written request to the
        Benefits Committee at least fifteen days prior to a Valuation Date.

        The amount to be withdrawn shall be taken from the Participant's Total
        Account in the following order, with the full amount available from each
        account to be fully withdrawn before any amount is taken from the next
        account:

        (a)    from the Participant's Rollover Account;
        (b)    from the Participant's Employer Matching Contribution Account;
        (c)    from the Participant's Regular Profit Sharing Account (to the
               extent vested);
        (d)    from the Participant's Cash Option Deferred Account;
        (e)    from the Participant's Supplemental Before-Tax Contribution
               Account; and 
        (f)    from the Participant's Basic Before-Tax Contribution Account.

        The distribution shall be made as soon as practicable following the
        Valuation Date following the date the application is received.

                                                                            (47)

9.3    POWERS AND DUTIES

       The Benefits Committee shall have and shall exercise complete
       discretionary authority to discharge its duties hereunder, including, but

       for changing or revoking such designation, and the authority to take such
       other action not inconsistent with the Plan or with any action of the

       final, binding and conclusive upon all persons concerned.


                                                                            (48)

       The Benefits Committee may retain or employ such legal, accounting and
       clerical assistance as it deems expedient in carrying out the provisions
       of the Plan, and may delegate to any member, or members of the Benefits
       Committee and/or any employee or employees of the Employer any
       ministerial or routine act or duty in connection with the administration
       of the Plan.

9.6    COMPENSATION OF BENEFITS COMMITTEE

       No Employee of the Employer who is a member of the Benefits Committee
       shall receive compensation for his services as a member, but a member of
       the Benefits Committee who is not an Employee may be compensated as the
       Board may determine.

9.7    PRUDENCE

       Any person serving as a member of the Benefits Committee shall use that
       standard of care, skill, prudence and diligence under the circumstances
       then prevailing that a prudent man acting in a like capacity and familiar
       with such matters would use in the conduct of an enterprise of a like
       character and with like aims.

9.8    CLAIMS PROCEDURE

       In the event that an Employee or Participant disagrees with any decision
       of the Benefits Committee regarding his rights to receive a benefit under
       the Plan, the amount of any such benefit, or any other factor affecting
       his rights under the Plan, the Employee or Participant may request a
       review of such decision, including a hearing before the full Benefits
       Committee concerning his rights. Such a request must be made in writing
       to the Benefits Committee within 60 days after receipt of such
       Committee's decision. The Employee or Participant shall be entitled to
       review documents pertinent to his claim and to submit issues and comments
       in writing to the Benefits Committee. The Benefits Committee shall within
       60 days after receiving the Employee's or Participant's request for a
       hearing, grant the


                                                                            (49)
<PAGE>   56
       Employee or Participant such a hearing, at which the Employee or
       Participant shall be entitled to have his attorney, or other person of
       his choice, present. Within 60 days after the request for a review is
       first received (or within 120 days after a request for a hearing is first
       received), the Benefits Committee shall issue a written decision to the
       Employee or Participant with respect to his case, giving specific reasons
       for its decision and specific references to the pertinent Plan provisions
       on which the decision is based.

9.9    INSURANCE

       The Benefits Committee shall have the right to purchase such insurance as
       it deems necessary to protect the Plan and the Fund from loss due to any
       breach of fiduciary responsibility by any person. Any premiums due on
       such insurance may be paid from Fund assets provided that, if such
       premiums are so paid, such policy of insurance must permit recourse by
       the insurer against the person who breaches his fiduciary responsibility.
       Nothing in this Section shall prevent the Benefits Committee or the
       Employer, at its, or his own expense, from providing insurance to any
       person to cover potential liability of that person as a result of a
       breach of fiduciary responsibility, nor shall any provisions of the Plan
       preclude the Employer from purchasing from any insurance company the
       right of recourse under any policy issued by such insurance company.


                                                                            (50)

       with the Trustee, except to the extent that the Trustee has delegated
       such responsibility to another Trustee or Trustees, as described in
       Section 10.5, or to an Investment Manager.

       The Trustee shall invest the assets of the Trust Fund in such stocks,
       bonds or other securities or certificates of participation or shares of
       any mutual investment company, trust or fund, or any other property of
       any kind, real or personal, tangible or intangible, as it may deem
       advisable, whether or not authorized under any present or future laws for
       the investment of trust funds, provided that the Trustee may hold funds
       of the Trust Fund uninvested without liability for interest if and to the
       extent that it may deem advisable from time to time; and the Trustee is
       authorized to commingle part or all of the assets of the Trust Fund in or
       with any one or more trusts created for the investments or collective
       investment of funds held under Employees' retirement benefit plans or
       trusts which are qualified within the meaning of and exempt from tax
       under the revenue laws of the United States, and permitted by existing or
       future rulings of the United States Treasury Department to pool their
       respective funds in a group trust, and the terms of any such collective
       investment trust shall be deemed incorporated herein and made a part
       hereof. The Trustee may accumulate and invest income.

       The Trustee, if a bank or trust company, is specifically authorized to
       maintain checking and earnings accounts in its own bank or trust company
       and is further authorized to purchase money market investments issued by
       itself. If otherwise permitted by law the Trustee may hold property in
       the name of a nominee without disclosure of its trust. No transfer agent,
       bank or other person dealing with the Trustee need inquire into the
       Trustee's authority to make transfers or need see to the application of
       property received by the Trustee.

       given by such Committee, and the Trustee shall have no other
       responsibility with respect to such distributions.

10.4   ALLOCATION OF RESPONSIBILITIES AMONG TRUSTEES REGARDING PLAN ASSETS

       agreement allocate any such specific responsibilities, obligations or
       duties among themselves as they deem advisable, including (without
       limitation) the duties of the Trustees respecting custody and
       registration of securities.

10.5   FIDUCIARY STATUS

       The Trustee is a fiduciary and shall discharge of its duties as set forth
       in the Plan and the requirements of law.

10.6   PLAN AND TRUST EXPENSES

      The Benefits Committee or the Sponsoring Employer may direct the Trustee
      to pay from the Trust Fund any or all expenses of administering the Plan
      and Trust, to the extent such expenses are reasonable. The Benefits
      Committee or the Sponsoring Employer will determine what constitutes a
      reasonable expense of administering the Plan and Trust, and whether such
      expenses shall be paid from the Trust Fund. Any such expenses not paid out
      of the Trust Fund shall be paid by the Sponsoring Employer; provided,
      however, that to the extent permitted by ERISA, the Benefits Committee or
      the Sponsoring Employer may direct the Trustee to reimburse the Sponsoring
      Employer out of the Trust Fund for a


                                                                            (52)

           either directly or by proxy.

       (b) TRANSFERS. The Trustee may buy, sell, mortgage, grant a security

           real or personal property on such terms as the Trustee deems proper;
           the Trustee shall take any action which the Benefits Committee
           directs regarding the sale or exchange of securities in connection
           with any merger or other reorganization described in the Code or
           otherwise; the Trustee may execute instruments of conveyance in such
           form as the Trustee deems proper.

           estate without assuming personal liability therefor.

       (d) LOANS. The Trustee may borrow and lend on such terms as the Trustee

           to sign checks and other commercial paper and engage in banking

           for deposits of funds of the Trust Fund.


                                                                            (53)

10.9   TRUSTEE'S ACCOUNTS

       The Trustee shall render periodic accounts to the Benefits Committee and
       the Employer. It shall have no duty to account to Participants and their
       Beneficiaries, who shall look exclusively to the Benefits Committee as
       Plan Administrator for disclosure and reporting.

       Within a reasonable time after the close of each fiscal year of the
       Employer, or of any termination of the duties of the Trustee hereunder,
       the Trustee shall prepare and deliver to the Benefits Committee an
       account of its acts and transactions as Trustee during such fiscal year
       or during such period from the close of the last fiscal year to the
       termination of the Trustee's duties, respectively, including a statement
       of the then current value of the Trust Fund. Any such account shall be
       deemed accepted and approved by the Benefits Committee, and the Trustee
       shall be relieved and discharged, as if such account had been settled and
       allowed by a judgment or decree of a court of competent jurisdiction,

       any account of the Trustee not previously settled as herein provided or
       for the determination of any question of construction or for
       instructions. In any such action or proceeding it shall be necessary to
       join as parties only the Trustee and the Benefits Committee (although the
       Trustee may also join such other parties as it may deem appropriate), and
       any judgment or decree entered therein shall be conclusive.

10.10  INDEMNIFICATION OF TRUSTEE

       The Employer shall indemnify and hold harmless the Trustee for any
       liability or expenses, including without limitation reasonable attorney's
       fees, incurred by the Trustee with respect to taking such investment
       direction as the Benefits Committee may authorize, and, in addition, with
       respect to holding, managing, investing or otherwise administering the
       Trust Fund, except for its lack of good faith or lack of due care or
       except as may be judicially determined.


                                                                            (54)

           last day of that Plan Year.

       (d) "AGGREGATION GROUP" means either:

             (i) A "REQUIRED AGGREGATION GROUP" which is each qualified plan of
                 an Employer or Affiliated Employer which provides benefits to a
                 Key Employee, and each other qualified plan of an Employer or
                 Affiliated Employer (including terminated plans maintained
                 within the five-year period ending on the Determination Date),
                 if any, which is included with such plan during the period of
                 five years ending on such plan's Determination Date for
                 purposes of meeting the requirements of Section 401(a)(4) or
                 Section 410 of the Code; or

            (ii) A "PERMISSIVE AGGREGATION GROUP" which is this Plan and each
                 other qualified plan of an Employer or Affiliated Employer
                 which in total would continue to meet the requirements of
                 Section 401(a)(4) and Section 410 of the Code with such other
                 qualified plan being taken into account (i.e., such other
                 qualified plan provides comparable benefits and satisfies the
                 coverage test).

       (e) "NON-KEY EMPLOYEE" means an employee who is not a Key Employee,
           including any employee who is a former Key Employee.


                                                                            (56)
<PAGE>   63
       (f) "VALUATION DATE" means the date used to calculate the value of
           account balances or accrued benefits for purposes of determining the
           top heavy ratio specified in Section 11.2.

           For purposes of this Plan, the Valuation Date shall be the
           Determination Date. For each other plan, the Valuation Date shall be,
           subject to Section 416 of the Code, the most recent Valuation Date
           which falls within or ends within the period of twelve months ending
           on the applicable determination date for such plan.

       (g) "EMPLOYEE," "FORMER EMPLOYEE," "KEY EMPLOYEE" and "NON-KEY EMPLOYEE"
           shall also include Beneficiaries of such an employee.

11.2   DETERMINATION OF TOP HEAVY STATUS

       The Plan shall be deemed a top heavy plan for a Plan Year if, as of a
       Valuation Date, the sum of the account balances of Key Employees under
       this Plan and all other defined contribution plans in the Aggregation
       Group, and the present value of accrued benefits of Key Employees under
       all defined benefit plans in the Aggregation Group exceeds 60% of the sum
       of the account balances of all Participants under this Plan and all other
       defined contribution plans in the Aggregation Group and the present value
       of accrued benefits of all Participants under all defined benefit plans
       in the Aggregation Group (but excluding participants who are former Key
       Employees). When aggregating plans, the value of account balances and
       accrued benefits will be calculated with reference to the Determination
       Dates that fall within the same calendar year.

       For purposes of this test, the following rules shall apply:

       (a) Subject to paragraph (b) below, any distributions made during the
           five Plan Years ending on the Determination Date shall be taken into
           account.

       (b) For Plan Years commencing after December 31, 1984, the accounts of
           all former employees who have not been credited with at least one
           Hour of Service during the period of five years ending on the
           Determination Date shall be disregarded, provided, however, that if
           such former Employee again completes an Hour of Service with the
           Employer after such five year period, such former Employee's accounts
           shall be taken into consideration.


                                                                            (57)
<PAGE>   64
       (c) If an employee is a Non-Key Employee for the Plan Year containing the
           Determination Date, but such individual was a Key Employee during any
           previous Plan Year, the value of his accounts shall not be taken into
           consideration.

       (d) Solely for purposes of determining if the Plan or any other plan in
           the Required Aggregation Group is a top heavy plan for a Plan Year,
           the accrued benefits of Non-Key Employees under any defined benefit
           plans shall be determined for Plan Years beginning after 1986 under
           the method, if any, which is uniformly applied for accrual purposes
           under all defined benefit plans maintained by an Employer or
           Affiliated Employer or, if there is no such method, as if such
           benefit accrued not more rapidly than under the slowest accrual rate
           permitted under Section 411(b)(1)(C) of the Code.

       (e) The determination of the present value of accrued benefits under all
           defined benefit plans in the Aggregation Group shall be based on the
           interest rate and mortality table specified in the qualified defined
           benefit plan maintained by the Sponsoring Employer.

       In no event shall the Plan be considered top heavy if it is part of a
       Required Aggregation Group or a Permissive Aggregation Group which is not
       top heavy.

11.3   PROCEDURES IN THE EVENT OF TOP HEAVY STATUS

       Notwithstanding any other provision of the Plan to the contrary, for any
       Plan Year in which the Plan is deemed to be top heavy, the following
       provisions shall apply:

       (a) Minimum Vesting - Any Participant who completes an Hour of Service in
           a Plan Year in which the Plan is deemed to be top heavy shall have a
           nonforfeitable interest in the Employer Profit Sharing Contribution
           made on his behalf to his Regular Profit Sharing Account for such
           Plan Year. Furthermore, if the vesting schedule under the Plan for
           any Plan Year shifts into or out of the above schedule because of the
           Plan's top heavy status, such shift shall be regarded as an amendment
           to the Plan's vesting schedule and the provisions of Section 7.4
           shall be applied.

       (b) Minimum Contribution - The Employer shall make a minimum contribution
           for each Participant who is a Non-Key Employee and who is employed by
           an Employer or Affiliated Employer on the last day of the Plan Year
           as follows:


                                                                            (58)
<PAGE>   65
             (i) If the Participant is also a participant in a defined benefit
                 plan or another defined contribution plan sponsored by an
                 Employer or Affiliated Employer which provides a top heavy
                 minimum benefit, then the minimum contribution to this Plan is
                 0%.

            (ii) If the Participant is also a participant in a defined benefit
                 plan or another defined contribution plan sponsored by an
                 Employer or Affiliated Employer which provides a top heavy
                 minimum benefit offset by the minimum benefit under this Plan,
                 or if the Participant is not a participant in any other defined
                 benefit plan or defined contribution plan sponsored by the
                 Employer, then the minimum contribution to this Plan is the
                 lesser of:

                 (A)  3% of the Participant's Section 415 Compensation (as
                      defined in Section 12.4(b)) for such Plan Year, or

                 (B)  The largest percentage of Employer contributions, as a
                      percentage of Section 415 Compensation (as defined in
                      Section 12.4(b)), allocated to the Total Account of any
                      Key Employee for such Plan Year.

                 For purposes of this paragraph (b)(ii), Participants shall also
                 include Eligible Employees who have waived participation in
                 this Plan, if applicable.

       (c) In any Plan Year in which the Plan is top heavy, but not super top
           heavy (substituting 90% for 60% in Section 11.2 above), Section
           12.4(e) shall be applied by substituting "1.0" for "1.25," unless
           subparagraph (b)(ii)(A) above is amended to substitute "4%" for "3%"
           therein.

       (d) In any Plan Year in which the Plan is super top heavy (substituting
           90% for 60% in Section 11.2), the factor of "1.25" shall be changed
           to "1.0" in Section 12.4(e).

       (e) In any Plan Year that the Plan ceases to be top heavy, the above
           provisions shall no longer apply, except that the portion of a
           Participant's Regular Profit Sharing Account which was vested
           pursuant to paragraph (a) above shall remain vested.

       (f) The minimum allocation provisions of paragraph (b) above shall, to
           the extent necessary, be satisfied by special contributions made by
           the Employer for that purpose. Neither Before-Tax Contributions nor
           Employer Matching Contributions


                                      (59)
<PAGE>   66
           shall be taken into account in satisfying the minimum allocation
           provisions of paragraph (b) above.

       (g) The provisions of this Section 11.3 above shall not apply to any
           Employee included in a unit of Employees covered by a collective
           bargaining agreement if, within the meaning of Section 416(i)(4) of
           the Code, retirement benefits were the subject of good faith
           bargaining.


                                                                            (60)

                            MISCELLANEOUS PROVISIONS


12.1   SPENDTHRIFT PROVISION

       No benefit payable under the Plan will, except as otherwise specifically
       provided by law, be subject in any manner to anticipation, alienation,
       sale, transfer, assignment, pledge, encumbrance or charge, and any
       attempt so to anticipate, alienate, sell, transfer, assign, pledge,
       encumber or charge the same will be void; nor will any benefit be in any
       manner liable for or subject to the debts, contracts, loans, liabilities,
       engagements or torts of the person entitled thereto, except for any loans
       or other indebtedness due the Trust Fund within the limitations stated in
       Section 4975(d)(3) of the Code and 1.401(a)-13 of the Code of Federal
       Regulations or similar substitute provisions of applicable regulation.
       Upon the occurrence or threatened occurrence of any act or thing in
       violation of or contrary to the foregoing provision, then the benefit
       affected will, in the discretion of the Benefits Committee, cease and
       terminate, and in that event the Benefits Committee will make or hold the
       payments which would otherwise be payable on account thereof to or for
       the benefit of the Participant or Beneficiary involved, his spouse,
       children or other dependents, or any of them, in such manner and in such
       proportion as the Benefits Committee may deem proper.

       This provision shall not apply to a Qualified Domestic Relations Order,
       and those other domestic relations orders permitted to be so treated by
       the Administrator under the provisions of the Retirement Equity Act of
       1984. The Administrator shall establish a written procedure to determine
       the qualified status of domestic relations orders and to administer
       distributions under such qualified orders. Further, to the extent
       provided under a Qualified Domestic Relations Order, a former spouse of a
       Participant shall be treated as the Spouse or surviving Spouse for all
       purposes under the Plan.

12.2   BONDING

       The requirement of giving bond by any Trustee or other fiduciary or of
       giving surety on any bond shall be dispensed with to the extent permitted
       or required by applicable law.


                                                                            (61)
<PAGE>   68
12.3   NO CONTRACTUAL OBLIGATIONS

       This Plan shall not constitute an express or implied contract between the
       Employer and any Participant and nothing contained herein shall give to
       any Employee or Participant the right to be retained in the employ of the
       Employer or to interfere with the management of the Employer's business
       or, except as otherwise provided by law, the right of the Employer to
       discharge any Employee or Participant at any time, nor shall it give the
       Employer the right to require any Employee to remain in its employ, nor
       shall it interfere with the right of any Employee to terminate his
       employment at any time.

12.4   LIMITATIONS ON CONTRIBUTIONS

       (a) The maximum annual addition that may be contributed or allocated to a
           Participant's accounts under this Plan, all other defined
           contribution plans, all individual medical accounts (as defined in
           Section 415(l)(2) of the Code) which are part of a defined benefit
           plan, and, with respect to contributions paid or accrued after
           December 31, 1985, all separate accounts for post-retirement medical
           benefits of key employees (as defined in Section 419A(d)(3) of the
           Code) under a welfare benefit fund (as defined in Section 419(e) of
           the Code), maintained by all Employers and Affiliated Employers for
           any Limitation Year commencing on or after January 1, 1987 shall not
           exceed the lesser of (i) or (ii) below:

             (i) $30,000 (or, if greater, 25% of the defined benefit dollar
                 limitation in effect under Section 415(b)(1)(A) of the Code for
                 the Limitation Year), or

            (ii) 25% of the Participant's "Section 415 Compensation" (as defined
                 in paragraph (b) below) for such Limitation Year.

       (b) The term "Section 415 Compensation" means wages, salaries, and fees
           for professional services and other amounts received from the
           Employer and all Affiliated Employers during the Limitation Year
           (without regard to whether or not an amount is paid in cash) for
           personal services actually rendered in the course of employment with
           the Employer, to the extent such amounts are includable in gross
           income, including, but not limited to, overtime pay, tips, bonuses,
           commissions to paid salesmen, compensation for services on the basis
           of a percentage of profits, commissions on insurance premiums, fringe
           benefits, reimbursements, and expense allowances, and excluding the
           following:


                                                                            (62)
<PAGE>   69
             (i) amounts contributed by the Employer or Affiliated Employer on
                 behalf of the Employee pursuant to a salary deferral agreement
                 under this Plan or any other cash or deferred arrangement
                 described in Section 401(k) of the Code, to any salary
                 reduction agreement pursuant to a cafeteria plan established
                 under Section 125 of the Code, or to any other plan of deferred
                 compensation, and which are not includable in the Employee's
                 gross income for the taxable year in which contributed, or any
                 distributions from a plan of deferred compensation;

            (ii) amounts realized from the exercise of a non-qualified stock
                 option, or when restricted stock (or property) held by the
                 Employee either becomes freely transferable or is no longer
                 subject to a substantial risk of forfeiture;

           (iii) amounts realized with respect to the sale, exchange, or other
                 disposition of stock acquired under a qualified stock option;
                 and

            (iv) other amounts which receive special tax benefits, or
                 contributions made by the Employer (whether or not under a
                 salary reduction agreement) towards the purchase of an annuity
                 described in Section 403(b) of the Code (whether or not the
                 amounts are excludable from the Employee's gross income).

           For Limitation Years beginning after December 31, 1991, for purposes
           of applying the limitations of this Section, the term "Section 415
           Compensation" means the compensation actually paid or includable in
           the Employee's gross income for the Limitation Year.

       (c) For purposes of the Plan, an annual addition consists of the amounts
           allocated to a Participant's accounts during the Limitation Year that
           constitute:

             (i) Employer Contributions (including Cash Option Deferrals) and
                 forfeitures allocable to a Participant under all plans (or
                 portions thereof) maintained by the Employer subject to Section
                 415(c) of the Code;

            (ii) the Participant's employee contributions under all such plans
                 (or portions thereof); and


                                                                            (63)
<PAGE>   70
           (iii) amounts allocated after March 31, 1984 to an individual medical
                 account (as defined in Section 415(l)(2) of the Code) under a
                 pension or annuity plan maintained by the Employer, or amounts
                 derived from contributions paid or accrued after December 31,
                 1985, in taxable years ending after such date, which are
                 attributable to post-retirement medical benefits, allocated to
                 the separate account of a key employee (as defined in Section
                 419(A)(d)(3) of the Code) under a welfare benefit fund (as
                 defined in Section 419(e) of the Code) maintained by the
                 Employer.

           Any excess amount applied under paragraph (d) below in the Limitation
           Year to reduce Employer Contributions shall be considered annual
           additions for such Limitation Year.

           A Participant's employee contributions as described in clause (ii)
           above shall be determined without regard to any rollover
           contributions, any employee contributions transferred directly from
           another plan qualified under Section 401(a) of the Code, or any Loan
           repayments.

           Employer and employee contributions taken into account as annual
           additions shall include "excess contributions" as defined in Section
           401(k)(8)(B) of the Code, "excess aggregate contributions" as defined
           in Section 401(m)(6)(B) of the Code, and "excess deferrals" as
           defined in Section 402(g) of the Code, regardless of whether such
           amounts are distributed or forfeited, unless such amounts constitute
           "excess deferrals" that were distributed to the Participant no later
           than April 15 of the taxable year following the taxable year of the
           Participant in which such deferrals were made.

       (d) In the event a Participant's total annual additions for a Limitation
           Year exceed the limitations of paragraph (a) above, Employer
           Contributions otherwise required with respect to such Participants
           under Article 5 shall be reduced to the extent necessary to comply
           with the limitations of paragraph (a) above. If such reduction is not
           effected in time to prevent such allocations for any Limitation Year
           from exceeding the limitations of paragraph (a), such excess amount
           shall, if permissible under Income Tax Regulation 1.415-6(b)(6)(iv),
           be distributed to the Participant. If such excess amount is not
           distributed, it shall be used to reduce Employer Contributions for
           such Participant in the next Limitation Year, and each succeeding
           Limitation Year, if necessary, provided that if the Participant is
           not covered by the Plan at the end of the current Limitation Year,
           the portion exceeding the limitation set forth in paragraph (a)


                                                                            (64)
<PAGE>   71
           above shall be held unallocated in a suspense account for such
           Limitation Year, and shall be reallocated in the next Limitation
           Year to the accounts of other Participants to the extent such
           allocations do not exceed the limitations of paragraph (a) above.

           All amounts held in the suspense account shall be used to reduce
           future Employer Contributions for all remaining Participants in
           succeeding Limitation Years (subject to the limitations of paragraph
           (a) above) before any Employer Contributions or Before-Tax
           Contributions which would constitute annual additions may be made to
           the Plan for the Limitation Year.

           If a suspense account is in existence at any time during a Limitation
           Year, it will participate in the allocation of the Trust Fund's
           investment gains or losses.

           Upon termination of the Plan, any unallocated amounts remaining in a
           suspense account shall be allocated to the extent possible under this
           Section for the Limitation Year of termination. Any amount remaining
           in such suspense account upon termination of the Plan shall be
           returned to the Employer, notwithstanding any other provision of the
           Plan or Trust Agreement.

       (e) If the Employer maintains, or at any time maintained, a qualified
           defined benefit plan covering any Participant in this Plan, the sum
           of the Participant's defined benefit plan fraction and defined
           contribution plan fraction (as described below) for any Limitation
           Year shall not exceed 1.0.

           The DEFINED BENEFIT PLAN FRACTION for any Limitation Year is a
           fraction, the numerator of which is the sum of the Participant's
           projected annual benefits under all defined benefit plans (whether or
           not terminated) maintained by the Employer, and the denominator of
           which is the lesser of 1.25 times the dollar limit determined under
           Sections 415(b) and 415(d) of the Code for the Limitation Year, or
           1.4 times 100% of the Participant's highest average annual Section
           415 Compensation (including any adjustments under Section 415(b) of
           the Code) for any three consecutive years.

           The DEFINED CONTRIBUTION PLAN FRACTION for any Limitation Year is a
           fraction, the numerator of which is the sum of the annual additions
           to the Participant's accounts under all defined contribution plans
           (whether or not terminated) maintained by the Employer for the
           current and all prior Limitation Years (including the annual
           additions attributable to the Participant's nondeductible employee
           contributions to all


                                      (65)
<PAGE>   72
           defined benefit plans (whether or not terminated) maintained by the
           Employer, and the annual additions attributable to all welfare
           benefit funds, as defined in Section 419(e) of the Code, and
           individual medical accounts, as defined in Section 415(l)(2) of the
           Code) maintained by the Employer, and the denominator of which is the
           sum of the maximum aggregate amounts for the current and all prior
           Limitation Years of service with the Employer (regardless of whether
           a defined contribution plan was maintained by the Employer). The
           maximum aggregate amount in any Limitation Year is the lesser of 1.25
           times the dollar limitation determined under Sections 415(b) and
           415(d) of the Code in effect under Section 415(c)(1)(A) of the Code,
           or 35% of the Participant's Section 415 Compensation for such
           Limitation Year.

           Any adjustment necessary to comply with the limitations of this
           paragraph (e) shall be made in the Participant's benefit payable
           under the relevant defined benefit plan; but under no circumstances
           may the accrued benefit of a Participant in a defined benefit plan
           decrease as a result of a Plan amendment to change the combined plan
           limits.

       (f) For purposes of this Section, the Employer and all Affiliated
           Employers shall be considered one employer, and the limitations shall
           be applicable to the total benefits received from the Employer and
           all Affiliated Employers. Furthermore, in determining who is an
           Affiliated Employer for this purpose, the phrase "more than 50%"
           shall be substituted for "at least 80%" each place it appears in
           Section 1563(a)(i) of the Code.

12.5   NONDISCRIMINATION LIMITATIONS ON PARTICIPANT CONTRIBUTIONS AND EMPLOYER
       MATCHING CONTRIBUTIONS

       (a) For purposes of this Section, the following terms shall have the
           meaning indicated below:

             (i) "ACTUAL DEFERRAL PERCENTAGE" means the average (expressed as a
                 percentage) of the deferral percentages of Eligible Employees
                 in a group. An Eligible Employee's deferral percentage is equal
                 to the ratio (expressed as a percentage) of the Employee's
                 Before-Tax Contributions and Cash Option Deferrals (including
                 any Before-Tax Contributions and Cash Option Deferrals returned
                 to the Employee pursuant to Section 4.5(b) but excluding
                 Before-Tax Contributions and Cash Option Deferrals returned to
                 the Employee pursuant to Section 12.4(d) contributed to the
                 Trust Fund in the Plan Year to the


                                      (66)
<PAGE>   73
                 Eligible Employee's Compensation for that Plan Year. The
                 individual ratios and the percentages for any groups of
                 individuals shall be calculated to the nearest one-hundredth
                 of one percent (.01%).

            (ii) "ACTUAL CONTRIBUTION PERCENTAGE" means the average (expressed
                 as a percentage) of the contribution percentages of Eligible
                 Employees in a group. An Eligible Employee's contribution
                 percentage is equal to the ratio of the Employer Matching
                 Contributions contributed to the Trust Fund in the Plan Year to
                 the Eligible Employee's Compensation for that Plan Year. The
                 individual ratios and the percentages for any groups of
                 individuals shall be calculated to the nearest one-hundredth of
                 one percent (.01%).

           (iii) "ELIGIBLE EMPLOYEE" means any Employee of the Employer who,
                 during the Plan Year, is eligible to make Before-Tax
                 Contributions or Cash Option Deferrals in accordance with the
                 provision of Sections 4.1 and 5.1 respectively, or who is
                 eligible to receive Employer Matching Contributions in
                 accordance with the provisions of Section 5.2. An individual
                 shall be treated as an Eligible Employee for a Plan Year if he
                 so qualifies for any part of the Plan Year.

            (iv) "COMPENSATION" means the Employee's Section 415 Compensation
                 (as defined in Section 12.4(b)) but not in excess of the limit
                 under Section 401(a)(17) of the Code, and including any amounts
                 contributed by the Employer or an Affiliated Employer on behalf
                 of the Employee pursuant to a salary deferral agreement or cash
                 option deferral under this Plan (or any other cash or deferred
                 arrangement described in Section 401(k) of the Code) or a
                 salary reduction agreement pursuant to a cafeteria plan
                 established under Section 125 of the Code, or toward the
                 purchase of an annuity described in Section 403(b) of the Code.

                 Notwithstanding the foregoing, in determining the amount of
                 Compensation to be taken into account for purposes of this
                 Section, the Employer may limit the period used to determine an
                 Employee's Compensation for the Plan Year to the portion of the
                 Plan Year in which the Employee was an Eligible Employee (as
                 defined in subparagraph (iii) above), provided that this limit
                 is applied uniformly to all Eligible Employees with respect to
                 such Plan Year.


                                      (67)
<PAGE>   74
       (b) For purposes of determining the Actual Deferral Percentage and Actual
           Contribution Percentage of an Eligible Employee who is a 5% owner or
           one of the ten most Highly Compensated Employees, and, for purposes
           of determining his excess contributions and excess aggregate
           contributions, if any, the Compensation, Before-Tax Contributions,
           Cash Optional Deferrals, and Employer Matching Contributions of such
           Employee shall include the Compensation, Before-Tax Contributions,
           Cash Option Deferrals, and Employer Matching Contributions for the
           Plan Year of his family members. For this purpose, the term "family
           member" means such Employee's Spouse and lineal ascendants and
           descendants, and the spouses of such lineal ascendants and
           descendants. Family members shall be disregarded in determining the
           Actual Deferral Percentage and Actual Contribution Percentage for
           Eligible Employees who are not 5% owners or among the ten most Highly
           Compensated Employees.

       (c) If more than one plan providing for a cash or deferred arrangement,
           or for matching contributions, or employee contributions (within the
           meaning of Sections 401(k) and 401(m) of the Code) is maintained by
           the Employer or an Affiliated Employer, then the individual ratios of
           any Highly Compensated Employee who participates in more than one
           such plan or arrangement shall, for purposes of determining the
           individual's Actual Contribution Percentage and Actual Deferral
           Percentage, be determined as if all such arrangements were a single
           plan or arrangement. If a Highly Compensated Employee participates in
           two or more cash or deferred arrangements that have different plan
           years, all cash or deferred arrangements ending with or within the
           same calendar year shall be treated as a single arrangement.
           Notwithstanding the foregoing, plans that are mandatorily
           disaggregated pursuant to regulations under Section 401(k) of the
           Code shall not be aggregated for purposes of this paragraph but shall
           be treated as separate plans.

       (d) In the event that this Plan satisfies the requirements of Sections
           401(a)(4) and 410(b) of the Code only if aggregated with one or more
           other plans, and for Plan Years beginning after December 31, 1988 all
           such plans have the same Plan Year, then this Section shall be
           applied by determining the Actual Deferral Percentage and Actual
           Contribution Percentage of Eligible Employees as if all such plans
           were a single plan.

       (e) In accordance with the nondiscrimination requirements of Section
           401(k) of the Code, the Committee shall establish a Compensation
           Deferral Limit with respect to Before-Tax Contributions and the Cash
           Option Share credited to a Participant's Total


                                      (68)

           Account during a Plan Year and may adjust such deferral limit (in
           accordance with paragraph (g)(i) below) from time to time during the
           Plan Year in order to satisfy one of the following tests:

             (i) The Actual Deferral Percentage of the group of Eligible
                 Employees who are Highly Compensated Employees for the Plan
                 Year shall not exceed the Actual Deferral Percentage of the
                 group of Eligible Employees who are Nonhighly Compensated
                 Employees for the same Plan Year multiplied by 1.25.

            (ii) The Actual Deferral Percentage of the group of Eligible
                 Employees who are Highly Compensated Employees for the Plan
                 Year shall not exceed the Actual Deferral Percentage of the
                 group of Eligible Employees who are Nonhighly Compensated
                 Employees for the same Plan Year multiplied by two, provided
                 that the Actual Deferral Percentage for such Highly Compensated
                 Employees is not more than two percentage points higher than
                 the Actual Deferral Percentage for such Nonhighly Compensated
                 Employees.

       (f) In accordance with the nondiscrimination requirements of Section
           401(m) of the Code, the Committee shall establish a Contribution
           Percentage Limit with respect to Employer Matching Contributions
           credited to a Participant's Total Account, and may adjust such
           percentage limit (in accordance with paragraph (g)(i) below) from
           time to time during the Plan Year in order to satisfy one of the
           following tests:

             (i) The Actual Contribution Percentage of the group of Eligible
                 Employees who are Highly Compensated Employees for the Plan
                 Year shall not exceed the Actual Contribution Percentage of the
                 group of Eligible Employees who are Nonhighly Compensated
                 Employees for the same Plan Year multiplied by 1.25.

            (ii) The Actual Contribution Percentage of the group of Eligible
                 Employees who are Highly Compensated Employees for the Plan
                 Year shall not exceed the Actual Contribution Percentage of the
                 group of Eligible Employees who are Nonhighly Compensated
                 Employees for the same Plan Year, multiplied by two, provided
                 that the Actual Contribution Percentage for such Highly
                 Compensated Employees is not more than two percentage points
                 higher than the Actual Contribution Percentage for such
                 Nonhighly Compensated Employees.


                                                                            (69)
<PAGE>   76
       (g) The Committee may take the following actions to assure compliance
           with the nondiscrimination limitations of Section 401(k) and/or
           Section 401(m) of the Code:

            (i)  If the average percentages described in paragraphs (e) and/or
                 (f) above applicable to the group of Eligible Employees who are
                 Highly Compensated Employees are expected to exceed the maximum
                 average percentage necessary to comply with the rules described
                 in said paragraphs, the Committee may direct that the Actual
                 Deferral Percentage and/or the Actual Contribution Percentage,
                 as the case may be, for each member of such group of Highly
                 Compensated Employees be reduced, prospectively only, beginning
                 with the Highly Compensated Employee whose Actual Deferral
                 Percentage or Actual Contribution Percentage, as the case may
                 be, is the highest so that the limit is not exceeded.

            (ii) If the average percentages described in paragraphs (e) and/or
                 (f) above applicable to the group of Eligible Employees who are
                 Highly Compensated Employees exceed the maximum average
                 percentage necessary to comply with the rules described in said
                 paragraphs, the Committee shall direct the successive
                 reductions of the highest individual Actual Deferral Percentage
                 and/or Actual Contribution Percentage attributable to one or
                 more members of such group of Highly Compensated Employees
                 (beginning with the Highly Compensated Employee whose Actual
                 Deferral Percentage or Actual Contribution Percentage, as the
                 case may be, is the highest) until the average percentage for
                 such group of Highly Compensated Employees does not exceed the
                 applicable limit.

           The reduction of a Highly Compensated Employee's Actual Deferral
           Percentage and/or Actual Contribution Percentage shall be made in
           accordance with the following procedure:

           FIRST, if a Highly Compensated Employee's Actual Deferral Percentage
           for the Plan Year exceeds the limit described in paragraph (e) above,
           his Actual Deferral Percentage shall be reduced by returning to him
           all (or a portion) of the amount contributed for such Plan Year in
           excess of such limit.


                                                                            (70)
<PAGE>   77
           Any amounts to be returned shall first be reduced, but not below
           zero, by any excess deferrals contributed for the Plan Year and
           previously returned to the Employee in the taxable year ending with
           or within that Plan Year pursuant to Section 4.5.

           The reduction of excess contributions shall be made by first reducing
           the Participant's Supplemental Before-Tax Contributions and, if that
           is insufficient, by reducing his Basic Before-Tax Contributions and,
           if that is insufficient, by reducing his Cash Option Deferrals.

           SECOND, in the case of a Participant to whom Basic Before-Tax
           Contributions are returned, the amount of his Employer Matching
           Contributions shall be reduced by distributing to the Participant his
           Employer Matching Contributions that were attributable to such Basic
           Before-Tax Contributions.

           THIRD, if a Highly Compensated Employee's Actual Contribution
           Percentage for the Plan Year exceeds the limit described in paragraph
           (f) above, his Actual Contribution Percentage shall be reduced by
           returning to him the amount contributed for such Plan Year in excess
           of such limit.

           The reduction of excess aggregate contributions shall be made by
           distributing Employer Matching Contributions to the Participant on a
           pro rata basis.

           Contributions which are returned, forfeited or distributed shall be
           adjusted for allocable gains and losses for the Plan Year with
           respect to which the contributions were made in accordance with the
           method described below for such contributions.

           ALLOCATING INCOME TO EXCESS CONTRIBUTIONS. Excess contributions shall
           be adjusted for allocable gains or losses for the Plan Year in which
           such excess contributions arose by multiplying the gains or losses
           credited to the Participant's Basic and Supplemental Before-Tax
           Contribution Accounts and Cash Option Deferred Account for such Plan
           Year by a fraction, the numerator of which is the Participant's
           excess contributions for the Plan Year, and the denominator of which
           is the sum of (i) the balance in the Participant's Basic and
           Supplemental Before-Tax Contribution Accounts and Cash Option
           Deferred Account as of the beginning of the Plan Year, and (ii) the
           amount of Before-Tax Contributions and Cash Option Deferrals credited
           to the Participant's Total Account for the Plan Year.


                                                                            (71)
<PAGE>   78
           ALLOCATING INCOME TO EXCESS AGGREGATE CONTRIBUTIONS. Excess aggregate
           contributions shall be adjusted for allocable gains or losses for the
           Plan Year in which such excess aggregate contributions arose by
           multiplying the gains or losses credited to the Participant's
           Employer Matching Contribution Account for such Plan Year by a
           fraction, the numerator of which is the Participant's excess
           aggregate contributions for the Plan Year, and the denominator of
           which is the sum of (i) the balance in the Participant's Employer
           Matching Contribution Account as of the beginning of the Plan Year,
           and (ii) the amount of Employer Matching Contributions credited to
           the Participant's Total Account for the Plan Year.

           Excess contributions and excess aggregate contributions (and income
           allocable thereto) shall be returned, distributed, or, if applicable,
           forfeited, not later than the last day of the Plan Year following the
           close of the Plan Year in which such excess arose. Excess
           contributions shall be allocated to Participants who are subject to
           the family aggregation rules of Section 414(q)(6) of the Code in the
           manner prescribed by applicable regulations.

       (i) For purposes of this Section, the "aggregate limit" for any Plan Year
           shall mean a percentage equal to the greater of (i) or (ii) below:

             (i) The percentage equal to the sum of (A) and (B) below:

                 (A) 125% of the greater of:

                      (1)  The Actual Deferral Percentage for Eligible Employees
                           who are Nonhighly Compensated Employees for the Plan
                           Year, or

                      (2)  The Actual Contribution Percentage of such Eligible
                           Employees, and

                 (B)  2% plus the lesser of (A)(1) or (A)(2) above. In no event,
                      however, shall this percentage exceed 200% of the lesser
                      of (A)(1) or (A)(2) above.

            (ii) The percentage equal to the sum of (A) and (B) below:

                 (A) 125% of the lesser of:


                                                                            (72)
<PAGE>   79
                      (1)  The Actual Deferral Percentage for Eligible Employees
                           who are Nonhighly Compensated Employees for the Plan
                           Year, or

                      (2)  The Actual Contribution Percentage of such Eligible
                           Employees, and

                 (B)  2% of the greater of (A)(1) or (A)(2) above. In no event,
                      however, shall this percentage exceed 200% of the greater
                      of (A)(1) or (A)(2) above.

           The "aggregate limit" shall be calculated to the nearest
           one-hundredth of one percent (.01%).

           The "aggregate limit" shall be applied to reduce allocations
           otherwise permissible for a Plan Year if after application of
           paragraph (g) above the sum of the average percentages described in
           paragraphs (e) and (f) above applicable to the group of Eligible
           Employees who are Highly Compensated Employees exceeds the "aggregate
           limit" for such Plan Year.

           The "aggregate limit" shall not apply to reduce allocations otherwise
           permissible for a Plan Year unless the Actual Deferral Percentage and
           the Actual Contribution Percentage for Eligible Employees who are
           Highly Compensated Employees for the Plan Year each exceed 125% of
           the corresponding percentages determined for Eligible Employees who
           are Nonhighly Compensated Employees for the Plan Year.

           The reduction of the Actual Contribution Percentage and/or Actual
           Deferral Percentage of the group of Eligible Employees who are Highly
           Compensated Employees shall be applied to those Highly Compensated
           Employees who are eligible to make Before-Tax Contributions or Cash
           Option Deferrals, or are eligible to receive Employer Matching
           Contributions. Reductions shall be made in the manner described in
           paragraph (g) above to the extent necessary to comply with the
           aggregate limit, except that the reductions shall be applied first to
           reduce Actual Contribution Percentages and then, if necessary, to
           reduce Actual Deferral Percentages.

       (j) The Committee shall maintain sufficient records to demonstrate that
           the Plan satisfies the nondiscrimination tests described in
           paragraphs (e) and (f) above.


                                                                            (73)
<PAGE>   80
12.6   LEASED EMPLOYEES

       For purposes of the Plan, the term "leased employee" means any person who
       would not otherwise be considered an Employee but who, pursuant to an
       agreement between the Employer or an Affiliated Employer and a leasing
       organization (within the meaning of Section 414(n)(2) of the Code) has
       performed services for the Employer or Affiliated Employer on a
       substantially full time basis for a period of at least one year, and such
       services are of a type historically performed by employees in the
       business field of the Employer or Affiliated Employer. Contributions or
       benefits provided a leased employee by the leasing organization which are
       attributable to services performed for the Employer or Affiliated
       Employer shall be treated as provided by the Employer or Affiliated
       Employer.

       A leased employee shall not be considered an Employee if:

       (a) Such individual is covered by a money purchase pension plan providing
           (i) a nonintegrated employer contribution rate of at least ten
           percent of his or her "Section 415 Compensation" (as defined in
           Section 12.4(b)), but including amounts contributed pursuant to a
           salary reduction agreement which are not includable in gross income
           under Section 125, 402(a)(8), 402(h), or 403(b) of the Code, (ii)
           immediate participation, and (iii) full and immediate vesting; and

       (b) leased employees constitute twenty percent or less of the Employer's
           or Affiliated Employer's nonhighly compensated workforce (within the
           meaning of Section 414(n)(5)(C)(ii) of the Code).

12.7   EXCLUSIVE BENEFIT OF PARTICIPANTS

       All assets of the Trust Fund shall be held for the exclusive purposes of
       providing benefits to Participants and Beneficiaries under the Plan and
       defraying reasonable expenses of administering the Plan. Except as
       otherwise provided in the Plan, or permitted by law, in no event shall it
       be possible, under the Plan for any part of the assets of the Trust Fund,
       whether principal or income, to be used for, or diverted to, purposes
       other than those stated herein.

12.8   RETURN OF CONTRIBUTIONS

       Nothing herein shall prohibit a return to the Employer, within one year
       after payment, of excess sums contributed to the Trust Fund as a result
       of a mistake of fact.


                                                                            (74)
<PAGE>   81
       In the event that the Commissioner of Internal Revenue (or his delegate)
       determines that the Plan is not initially qualified under the Code, any
       Employer contributions made to the Plan shall be returned to the Employer
       within one year after the date the initial qualification is denied,
       provided application for qualification is made by the time prescribed by
       law for filing the Employer's return for the Fiscal Year in which the
       Plan is adopted, or such later date as the Secretary of the Treasury may
       prescribe.

       Each Employer contribution is conditioned on the deductibility of the
       contribution under Section 404 of the Code, and to the extent such
       contribution deduction is disallowed, the contribution shall be returned
       to the Employer within one year after the date of disallowance.


                                                                            (75)

                                  ARTICLE 13

                            AMENDMENT AND TERMINATION

13.1   AMENDMENT

       The Sponsoring Employer may amend the Plan, from time to time, by a
       written instrument duly executed by an authorized officer of the
       Sponsoring Employer pursuant to a resolution of the Board and delivered
       to the Trustee, provided that no amendment which affects the Trustee
       shall be effective without the Trustee's consent.

13.2   MERGER, CONSOLIDATION OR TRANSFER OF ASSETS

       In the case of any merger or consolidation of the Trust Fund with, or
       transfer of assets or liabilities of the Trust Fund to, any trust under
       any other plan, such transaction shall be structured in such a way that
       each Participant would (if the Plan then terminated) receive a benefit
       immediately after the transaction which is equal to or greater than the
       benefit he would have been entitled to receive immediately before the
       transaction (if the Plan had then terminated).

13.3   TERMINATION

       The Sponsoring Employer may terminate the Plan established hereunder at
       its option at any time by written resolution of the Board. Without
       thereby undertaking a legal duty, however, the Sponsoring Employer hereby
       expresses the intention of establishing a permanent plan under which the
       Sponsoring Employer will make recurring and substantial contributions.
       The Plan shall be automatically terminated if the Sponsoring Employer is
       adjudicated bankrupt, makes an assignment for benefit of creditors,
       suffers the appointment of a receiver, or dissolves, except that the
       reorganization of the Employer under the applicable sections of the Code
       shall not be deemed to result in dissolution for purposes of this Section
       13.3.

       A participating Employer may discontinue or revoke its participation in
       the Plan with respect to its Eligible Employees. At the time of
       discontinuance or revocation, the Committee may authorize the Trustee to
       transfer, deliver, and assign vested Trust Fund assets attributable to
       the Participants employed by such participating Employer to a new trustee
       as shall have been designated by the participating Employer, in the event
       that it has


                                      (76)
<PAGE>   83
       established a separate qualified plan for its employees. If a separate
       qualified plan is not established, the Trustee shall retain such assets
       for the benefit of the Participants employed by such participating
       Employer. In no event shall any part of the corpus or income of the Trust
       Fund as it relates to such participating Employer be used for or diverted
       to purposes other than for the exclusive benefit of the Participants
       employed by such participating Employer and their Beneficiaries.

13.4   CONSEQUENCES OF TERMINATION

       In the event that the Board shall decide to terminate the Plan, or in the
       event of a partial termination or complete cessation of Employer
       Contributions, the rights of Participants to the amounts in their Total
       Accounts shall be fully vested. Thereupon, the Benefits Committee shall
       direct the Trustee to liquidate the entire Trust Fund after payment of
       all expenses and proportional adjustment of Total Accounts to reflect
       such expenses and the value of the Fund. The Trustees shall make payment
       of all amounts due to the Participants in accordance with the applicable
       provisions of the Plan.

IN WITNESS WHEREOF, and as conclusive evidence of the adoption of this Plan
instrument by the Sponsoring Employer and the Trustee, the Sponsoring Employer
and the Trustee have caused these presents to be executed on their behalf and
the Corporate Seal of the Sponsoring Employer is to be hereunder affixed as of
this 7th day of July, 1997.

Attest:  _____________________________



<PAGE>   85
                                   EXHIBIT A

       SPECIAL PROVISIONS APPLICABLE TO FORMER PARTICIPANTS OF THE SBERA
                  401(K) PLAN ADOPTED BY THE BANK OF BRAINTREE

The following provisions shall be applicable to Participants who were formerly 
participants in the SBERA 401(k) Plan Adopted by The Bank of Braintree (Prior 
Plan) with respect to their account balances (Merged Account or Merged Account 
Balances) under the Prior Plan that was merged into the UST Corp. Employee 
Savings Plan effective June 30, 1997.

1.  "MERGED ACCOUNT OR MERGED ACCOUNT BALANCE" shall mean the Participant's
    total account balance under the Prior Plan as of June 30, 1997, plus any
    investment earnings (or losses) on such account subsequent to such date and
    up to the date of distribution.

2.  With respect to each Participant's Merged Account Balance the following
    provisions shall also apply in addition to the provisions set forth in the
    Plan with regard to options upon distribution:

        AUTOMATIC ANNUITY  The Participant's Merged Account will be applied to 
        purchase a Qualified Joint & Survivor Annuity for a married 
        Participant. If the Participant is not married the Participant's Merged 
        Account will be applied to purchase a life annuity. In the 90 day 
        period prior to his annuity starting date the Participant may make a 
        Qualified Election to receive an alternative distribution. A 
        Participant may elect to have such annuity distributed upon the 
        attainment of the Participant's Earliest Retirement Age. A deceased 
        Participant's Merged Account will be paid as a death benefit to the 
        surviving Spouse or Beneficiary. Unless an Optional form of benefit 
        within the Election Period pursuant to a Qualified Election has been 
        selected, the surviving Spouse may elect distribution of the automatic 
        pension within a reasonable period after the Participant's death.

        NOTICE a) In the case of a Qualified Joint & Survivor Annuity notice 
        shall be provided not less than 30 days or more than 90 days prior to 
        the annuity starting date and in the case of a Qualified Preretirement 
        Survivor Annuity the later of the following periods that ends last: i) 
        the period beginning the first day of the Plan Year the Participant 
        attains age 32 and ending the last day of the Plan Year preceding the 
        Plan Year the Participant attains age 35 or ii) the period beginning 
        one year prior to and ending one year after the date the Employee 
        becomes a Participant or iii) the period one year before and ending one 
        year after this section first applies to the Participant or iv) the 
        period beginning one year prior to and ending one year after this 
        section ceased to apply to the Participant. Notice shall be provided 
        within the period beginning one year prior to and ending one year 
        following the date employment terminates for a Participant who has not 
        attained age 35. If such Participant is reemployed the applicable 
        period shall be redetermined. A Participant may elect, with appropriate 
        spousal consent, to waive the requirement that the written notice be 
        provided at least 30 days prior to the annuity starting date provided 
        such distribution commences more than 7 days after the notice is 
        provided.
<PAGE>   86
SBERA Exhibit A
6/30/97
Page 2


b) Notwithstanding this section, the respective notices prescribed by this
section need not be given to a Participant if the Plan fully subsidizes the
costs of a Qualified Joint and Survivor Annuity or a Qualified Preretirement
Survivor Annuity and the Plan does not allow the Participant to waive the
Qualified Joint and Survivor Annuity or the Qualified Preretirement Survivor
Annuity and does not allow a married Participant to designate a non-Spouse
Beneficiary.

The notice will be written and will inform the Participant that his vested
Merged Account Balance will be paid as a Qualified Joint & Survivor Annuity
unless an alternate distribution method is selected in a Qualified Election.

The notice will include an explanation of the terms and conditions of a
Qualified Joint and Survivor Annuity or a Qualified Preretirement Survivor
Annuity, the effect of an Election to waive the Qualified Joint and Survivor
Annuity, the Spouse's right regarding the required consent, the right to make
and the effect of revoking an Election, and a statement of any benefits which
may be forfeitable for any reason including death.

If a Participant elects to receive distribution in one sum or in a series of
sums which may constitute a lump sum distribution, the Plan Administrator will
furnish notice using a format provided by the Secretary of Treasury explaining
that the distribution is not taxable currently to the extent transferred to
another qualified Plan or individual retirement account or individual retirement
annuity within 60 days after the date of its receipt and that the 60 day period
begins when the last distribution is made, and 10 or 5 year income averaging
and/or capital gains income tax provisions may apply.

"ELECTION" means a written instrument executed by a Participant and filed with
the Plan Administrator on or before its effective date, exercising one or more
rights under this Plan.

"ELECTION PERIOD" means the period beginning on the first day of the Plan Year
in which the Participant attains age 35 and ending on the date of his death. If
a Participant separates from service prior to the first day of the Plan Year in
which he is 35, the Election Period shall begin on the date his employment
terminates. A Participant may make a special Qualified Election to waive the
Qualified Preretirement Survivor Annuity for the period beginning on the date of
such Election and ending on the first day of the Plan Year in which he attains
age 35 provided that the Participant has received a written explanation of the
Qualified Preretirement Survivor Annuity stating that such coverage will be
reinstated as of the first day of the Plan Year in which he attains age 35. Any
new waiver on or after such date shall be subject to the full extent of this
Article.

"EARLIEST RETIREMENT AGE" means the date on which the Participant can elect to
receive retirement benefits.

"QUALIFIED ELECTION" means a waiver of a Qualified Joint and Survivor Annuity or
a Qualified Preretirement Survivor Annuity neither of which shall be effective
unless: the Spouse gives written consent to the Election; the Election
designates a specific Beneficiary

<PAGE>   87
SBERA Exhibit A
6/30/97
Page 3


     or Beneficiaries or contingent Beneficiaries, which may not be changed
     without spousal consent unless the Spouse has permitted the Participant to
     change designations without further consent; the Spouse's consent
     acknowledges the effect of the Election; and the Spouse's consent is
     witnessed by a Plan representative or Notary Public. If it is established
     to the satisfaction of a Plan representative that written consent may not
     be obtained because there is no Spouse or the Spouse cannot be located, a
     waiver will be deemed a Qualified Election.

     "QUALIFIED JOINT AND SURVIVOR ANNUITY" means the actuarial equivalent of a
     straight life annuity paid to the Participant and his spouse for their
     joint lives and reduced by 50% at the first death.

     "QUALIFIED PRERETIREMENT SURVIVOR ANNUITY" means a straight life annuity
     paid to the Participant's spouse by applying the Participant's Merged
     Account Balance to the purchase of such an annuity.

     Consent, or the deemed consent of a Spouse shall be effective only with
     respect to such Spouse. Consent that permits designations by the
     Participant without requirement of further consent by such Spouse shall
     acknowledge that the Spouse has the right to limit consent to a specific
     Beneficiary, and a specific form of benefit, and that the Spouse
     voluntarily elects to relinquish either or both such rights. A Participant
     may revoke a waiver without Spouse consent at any time before benefits
     commence without limit. Consent shall not be valid unless the Participant
     has received Notice under this section.

     Subject to the above limitations, distributions may also be made over one
     of the following periods.

     a) the life of the Participant, or the life of the Participant and the life
        of the Designated Beneficiary; and

     b) the period contains not greater than the Participant's life expectancy
        or the joint and last survivor life expectancy of the Participant and
        his or her Beneficiary.

     Distributions based on a life contingency or period certain will be made by
     applying the Participant's Merged Account to purchase a non-transferable
     annuity from an insurance company to provide the benefit for the
     Participant.

3. With respect to each Participant's Merged Account Balance, the following
   provisions shall also apply with respect to hardship distributions.

     HARDSHIP DISTRIBUTION Distribution of Before-Tax Contributions (and
     earnings thereon accrued as of December 31, 1988) out of a Participant's
     Merged Account Balance may be made to a Participant in the event of
     hardship. For the purposes of this section, hardship is defined as an
     immediate and heavy financial need of the Employee where such Employee
     lacks other available resources. Hardship Distributions are subject to the
     spousal consent requirements contained in IRC 401(a)(11) and 417.


 
<PAGE>   88
SBERA Exhibit A
6/30/97
Page 4

     The following are the only financial needs considered immediate and heavy:
     funeral expenses of an immediate family member, deductible medical expenses
     (within the meaning of IRC 213(d)) of the Employee, the Employee's spouse,
     children, or dependents; the purchase (excluding mortgage payments) of a
     principal residence for the Employee; payment of tuition for the next
     quarter or semester of post-secondary education for the Employee, the
     Employee's spouse, children or dependents; or the need to prevent the
     eviction of the Employee from, or a foreclosure on the mortgage of, the
     Employee's principal residence, including any federal, state or local taxes
     or penalties reasonably expected to result from the distribution.

     A distribution will be considered as necessary to satisfy an immediate and
     heavy financial need of the Employee only if:

     a) The Employee has obtained all distributions, other than Hardship
        Distributions, and all non-taxable loans under all Plans maintained by
        the Employer;

     b) All Plans maintained by the Employer provide that the Employee's
        Before-Tax Contributions (and employee contributions) will be suspended
        for twelve months after the receipt of the Hardship Distribution;

     c) The distribution is not in excess of the amount of an immediate and
        heavy financial need; and

     d) All Plans maintained by the Employer provide that the Employee may not
        make Before-Tax Contributions for the Employee's taxable year
        immediately following the taxable year of the Hardship Distribution in
        excess of the applicable limit under IRC 402(g) for such taxable year
        less the amount of such Employee's Before-Tax Contributions for the
        taxable year of the Hardship Distribution.

                  (i)   Forfeitures shall first be used to pay any Plan expenses
                        that may be authorized pursuant to Section 10.6 of the
                        Plan;

                  (ii)  Any remaining forfeitures shall then be used to reduce
                        Employer Contributions made pursuant to Section 5.1 and
                        Section 5.2; and

                  (iii) Any remaining forfeitures shall then be allocated to
                        Participant's Regular Profit Sharing Accounts and/or
                        ESOP Accounts in the same manner as set forth in Section
                        5.1(c).

            (b)   Rehire - Repayments Permitted Within Five Years of
                  Reemployment:

                  In the event a Participant described in subparagraph (a) above
                  is rehired prior to incurring five consecutive One-Year Breaks
                  in Service, the Participant shall be permitted to repay to his
                  Total Account the entire amount of the distribution in order
                  to restore the nonvested portion of his Regular Profit Sharing
                  Account or ESOP Account balance for the purpose of future
                  vesting as if he had not separated from Service and received a
                  distribution. The permissible repayment period shall continue
                  until the fifth anniversary of the day on which the Employer
                  reemploys the Employee.

                  If such repayment is not made before such period, such
                  Participant's vested amount will be determined by including
                  Years of Service accrued before such Participant's separation
                  from Service but without regard to amounts allocated prior to
                  such separation.

                  In the event that the terminated Participant's vested balance
                  in his Regular Profit Sharing Account or ESOP Account was
                  zero,

                  (A)   distribution of the vested balance in his Regular Profit
                        Sharing Account or ESOP Account shall be deemed to have
                        been made to him as of the date of his termination of
                        employment,

                                       8
<PAGE>   99
                  (B)   repayment shall be deemed to be made on his reemployment
                        commencement date, and

                  (C)   the balance in his Regular Profit Sharing Account or
                        ESOP Account shall be restored accordingly.

            (c)   Restoration of Regular Profit Sharing Account or ESOP Account
                  Balances:

                  A Participant who made or who is deemed to have made a
                  repayment pursuant to paragraph (b) above will have recredited
                  to his Regular Profit Sharing Account or ESOP Account, as of
                  the last day of the Plan Year coinciding with or next
                  following his date of rehire, the portion of such Account
                  balance which he forfeited upon his prior termination from
                  Service with the Employer unadjusted for any subsequent gains
                  or losses. The sources for restoring a previous forfeiture in
                  a subsequent year will be, in order of priority:

                  (A)   Earnings allocable to the Plan's Regular Profit Sharing
                        Account or ESOP Account balances for the Plan Year in
                        which such Account balance is recreated, if still not
                        sufficient then;

                  (B)   Contributions made by the Employer for the Plan Year in
                        which the Regular Profit Sharing Account or ESOP Account
                        balance is recreated.

            (d)   Rehire After Five Years:

                  In the event a former Participant is rehired after incurring
                  five consecutive One-Year Breaks in Service, the portion of
                  the Participant's Regular Profit Sharing Account or ESOP
                  Account which he forfeited shall not be recredited to the
                  Participant's Regular Profit Sharing Account or ESOP Account
                  if he subsequently becomes eligible to participate in the
                  Plan, except as follows:

                  (A)   Such former Participant shall have his prior nonvested
                        portion in his Regular Profit Sharing Account or ESOP
                        Account restored, if such former Participant repays the
                        entire amount of the distribution he previously received
                        under the Plan (upon his prior termination) by the close
                        of five consecutive One-Year Breaks in Service
                        commencing after such prior distribution.

                  (B)   To the extent applicable, the procedures of paragraph
                        (c) above shall apply to the restoration of the
                        Participant's nonvested portion of his Regular Profit
                        Sharing Account or ESOP

                        Account if he repays his prior distribution under this
                        paragraph (d)."

25.   Effective January 1, 1997, Section 12.5 of the Plan is amended to read as
      follows:

      "12.5 NONDISCRIMINATION LIMITATIONS ON PARTICIPANT CONTRIBUTIONS AND
            EMPLOYER MATCHING CONTRIBUTIONS

            (a)   For purposes of this Section, the following terms shall have
                  the meaning indicated below:

                  (i)   "ACTUAL DEFERRAL PERCENTAGE" means the average
                        (expressed as a percentage) of the deferral percentages
                        of Eligible Employees in a group. An Eligible Employee's
                        deferral percentage is equal to the ratio (expressed as
                        a percentage) of the Employee's Before-Tax Contributions
                        and Cash Option Deferrals (including any Before-Tax
                        Contributions and Cash Option Deferrals returned to the
                        Employee pursuant to Section 4.5(b) but excluding
                        Before-Tax Contributions and Cash Option Deferrals
                        returned to the Employee pursuant to Section 12.4(d)
                        contributed to the Trust Fund in the Plan Year to the
                        Eligible Employee's Compensation for that Plan Year. The
                        individual ratios and the percentages for any groups of
                        individuals shall be calculated to the nearest
                        one-hundredth of one percent (.01%).

                  (ii)  "ACTUAL CONTRIBUTION PERCENTAGE" means the average
                        (expressed as a percentage) of the contribution
                        percentages of Eligible Employees in a group. An
                        Eligible Employee's contribution percentage is equal to
                        the ratio of the Employer Matching Contributions
                        contributed to the Trust Fund in the Plan Year to the
                        Eligible Employee's Compensation for that Plan Year. The
                        individual ratios and the percentages for any groups of
                        individuals shall be calculated to the nearest
                        one-hundredth of one percent (.01%).

                  (iii) "ELIGIBLE EMPLOYEE" means any Employee of the Employer
                        who, during the Plan Year, is eligible to make
                        Before-Tax Contributions or Cash Option Deferrals in
                        accordance with the provisions of Sections 4.1 and 5.1
                        respectively, or who is eligible to receive Employer
                        Matching Contributions in accordance with the provisions
                        of Section 5.2. An individual shall be treated as an
                        Eligible Employee for a Plan Year if he so qualifies for
                        any part of the Plan Year.

<PAGE>   102
                  (iv)  "COMPENSATION" means the Employee's Section 415
                        Compensation (as defined in Section 12.4(b)) but not in
                        excess of the limit under Section 401(a)(17) of the
                        Code, and including any amounts contributed by the
                        Employer or an Affiliated Employer on behalf of the
                        Employee pursuant to a salary deferral agreement or Cash
                        Option Deferral under this Plan (or any other cash or
                        deferred arrangement described in Section 401(k) of the
                        Code) or a salary reduction agreement pursuant to a
                        cafeteria plan established under Section 125 of the
                        Code, or toward the purchase of an annuity described in
                        Section 403(b) of the Code.

                        Notwithstanding the foregoing, in determining the amount
                        of Compensation to be taken into account for purposes of
                        this Section, the Employer may limit the period used to
                        determine an Employee's Compensation for the Plan Year
                        to the portion of the Plan Year in which the Employee
                        was an Eligible Employee (as defined in subparagraph
                        (iii) above), provided that this limit is applied
                        uniformly to all Eligible Employees with respect to such
                        Plan Year.

            (b)   If more than one plan providing for a cash or deferred
                  arrangement, or for matching contributions, or employee
                  contributions (within the meaning of Sections 401(k) and
                  401(m) of the Code) is maintained by the Employer or an
                  Affiliated Employer, then the individual ratios of any Highly
                  Compensated Employee who participates in more than one such
                  plan or arrangement shall, for purposes of determining the
                  individual's Actual Contribution Percentage and Actual
                  Deferral Percentage, be determined as if all such arrangements
                  were a single plan or arrangement. If a Highly Compensated
                  Employee participates in two or more cash or deferred
                  arrangements that have different plan years, all cash or
                  deferred arrangements ending with or within the same calendar
                  year shall be treated as a single arrangement. Notwithstanding
                  the foregoing, plans that are mandatorily disaggregated
                  pursuant to regulations under Section 401(k) of the Code shall
                  not be aggregated for purposes of this paragraph but shall be
                  treated as separate plans.

            (c)   In the event that this Plan satisfies the requirements of
                  Sections 401(a)(4) and 410(b) of the Code only if aggregated
                  with one or more other plans, and for Plan Years beginning
                  after December 31, 1988 all such plans have the same Plan
                  Year, then this Section shall be applied by determining the
                  Actual Deferral Percentage and Actual Contribution Percentage
                  of Eligible Employees as if all such plans were a single plan.

            (d)   In accordance with the nondiscrimination requirements of
                  Section 401(k) of the Code, the Committee shall establish a
                  Compensation Deferral

                  Limit with respect to Before-Tax Contributions and the Cash
                  Option Deferral credited to a Participant's Total Account
                  during a Plan Year and may adjust such deferral limit (in
                  accordance with paragraph (f)(i) below) from time to time
                  during the Plan Year in order to satisfy one of the following
                  tests:

                  (i)   The Actual Deferral Percentage of the group of Eligible
                        Employees who are Highly Compensated Employees for the
                        Plan Year shall not exceed the Actual Deferral
                        Percentage of the group of Eligible Employees who are
                        Nonhighly Compensated Employees for the same Plan Year
                        multiplied by 1.25.

                  (ii)  The Actual Deferral Percentage of the group of Eligible
                        Employees who are Highly Compensated Employees for the
                        Plan Year shall not exceed the Actual Deferral
                        Percentage of the group of Eligible Employees who are
                        Nonhighly Compensated Employees for the same Plan Year
                        multiplied by two, provided that the Actual Deferral
                        Percentage for such Highly Compensated Employees is not
                        more than two percentage points higher than the Actual
                        Deferral Percentage for such Nonhighly Compensated
                        Employees.

                  (iii) Amounts in excess of these limits in (d) are called
                        "Excess Contributions".

            (e)   In accordance with the nondiscrimination requirements of
                  Section 401(m) of the Code, the Committee shall establish a
                  Contribution Percentage Limit with respect to Employer
                  Matching Contributions credited to a Participant's Total
                  Account, and may adjust such percentage limit (in accordance
                  with paragraph (f)(i) below) from time to time during the Plan
                  Year in order to satisfy one of the following tests:

                  (i)   The Actual Contribution Percentage of the group of
                        Eligible Employees who are Highly Compensated Employees
                        for the Plan Year shall not exceed the Actual
                        Contribution Percentage of the group of Eligible
                        Employees who are Nonhighly Compensated Employees for
                        the same Plan Year multiplied by 1.25.

                  (ii)  The Actual Contribution Percentage of the group of
                        Eligible Employees who are Highly Compensated Employees
                        for the Plan Year shall not exceed the Actual
                        Contribution Percentage of the group of Eligible
                        Employees who are Nonhighly Compensated Employees for
                        the same Plan Year, multiplied by two, provided that the
                        Actual Contribution Percentage for such Highly
                        Compensated Employees is not more than two percentage

                        higher than the Actual Contribution Percentage for such
                        Nonhighly Compensated Employees.

                  (iii) Amounts in excess of these limits in (e) are called
                        "Excess Aggregate Contributions".

            (f)   The Committee may take the following actions to assure
                  compliance with the nondiscrimination limitations of Section
                  401(k) and/or Section 401(m) of the Code:

                  (i)   If the average percentages described in paragraphs (d)
                        and/or (e) above applicable to the group of Eligible
                        Employees who are Highly Compensated Employees are
                        expected to exceed the maximum average percentage
                        necessary to comply with the rules described in said
                        paragraphs, the Committee may direct that the Actual
                        Deferral Percentage and/or the Actual Contribution
                        Percentage, as the case may be, for each member of such
                        group of Highly Compensated Employees be reduced,
                        prospectively only, beginning with the Highly
                        Compensated Employee whose Actual Deferral Percentage or
                        Actual Contribution Percentage, as the case may be, is
                        the highest so that the limit is not exceeded.

                  (ii)  If the average percentages described in paragraphs (d)
                        and/or (e) above applicable to the group of Eligible
                        Employees who are Highly Compensated Employees exceed
                        the maximum average percentage necessary to comply with
                        the rules described in said paragraphs, the Committee
                        shall direct that any distribution of Excess
                        Contributions or Excess Aggregate Contributions shall be
                        made to Highly Compensated Employees on the basis of the
                        amount of Before-Tax Contributions and Cash Option
                        Deferrals in the case of percentages described in (d)
                        and the amount of Employer Matching Contributions in the
                        case of percentages described in (e) in accordance with
                        the following method. The Committee shall first
                        calculate the dollar amount of the Excess Contributions
                        or Excess Aggregate Contributions described in
                        paragraphs (d) and (e), respectively. The Before-Tax
                        Contributions and Cash Option Deferral or the Employer
                        Matching Contributions of the Highly Compensated
                        Employee with the highest dollar amount shall be reduced
                        to equal the dollar amount of Before-Tax Contributions
                        or Cash Option Deferral or Employer Matching
                        Contributions of the Highly Compensated Employee with
                        the next highest dollar amount. This amount shall be
                        distributed to such Highly Compensated Employee.
                        However, if a lesser reduction when added to the total
                        dollar amount already distributed under this 

                                       14
<PAGE>   105
                        step would equal the total Excess Contributions or
                        Excess Aggregate Contributions, the lesser reduction
                        shall be distributed. If the total amount distributed is
                        less than the total Excess Contributions or Excess
                        Aggregate Contributions, the above process will be
                        repeated until the total dollar amount of Excess
                        Contributions or Excess Aggregate Contributions, as the
                        case may be, is distributed.

                        Once distribution of the total Excess Contributions or
                        Excess Aggregate Contributions is made, the
                        nondiscrimination tests of Code Sections 401(k)(3) or
                        401(m)(3) are deemed satisfied. In the event that any
                        Basic Before-Tax Contributions are returned as described
                        above, the amount of such Participant's Employer
                        Matching Contributions attributable to the returned
                        Basic Before-Tax Contributions shall be forfeited and
                        used to reduce Employer Matching Contributions.

                  (iii) ALLOCATING INCOME TO EXCESS CONTRIBUTIONS. Any returned
                        Excess Contributions shall be adjusted for allocable
                        gains or losses for the Plan Year in which such excess
                        contributions arose by multiplying the gains or losses
                        credited to the Participant's Basic and Supplemental
                        Before-Tax Contribution Accounts and Cash Option
                        Deferral Account for such Plan Year by a fraction, the
                        numerator of which is the Participant's returned Excess
                        Contributions for the Plan Year, and the denominator of
                        which is the sum of (i) the balance in the Participant's
                        Basic and Supplemental Before-Tax Contribution Accounts
                        and Cash Option Deferral Account as of the beginning of
                        the Plan Year, and (ii) the amount of Before-Tax
                        Contributions and Cash Option Deferrals credited to the
                        Participant's Total Account for the Plan Year.

                  (iv)  ALLOCATING INCOME TO EXCESS AGGREGATE CONTRIBUTIONS. Any
                        returned excess aggregate contributions shall be
                        adjusted for allocable gains or losses for the Plan Year
                        in which such excess aggregate contributions arose by
                        multiplying the gains or losses credited to the
                        Participant's Employer Matching Contribution Account for
                        such Plan Year by a fraction, the numerator of which is
                        the Participant's returned Excess Aggregate
                        Contributions for the Plan Year, and the denominator of
                        which is the sum of (i) the balance in the Participant's
                        Employer Matching Contribution Account as of the
                        beginning of the Plan Year, and (ii) the amount of
                        Employer Matching Contributions credited to the
                        Participant's Total Account for the Plan Year.

                        Excess Contributions and Excess Aggregate Contributions
                        (and income allocable thereto) shall be returned,
                        distributed, or, if applicable, forfeited, not later
                        than the last day of the Plan Year following the close
                        of the Plan Year in which such excess arose.

                  (g)   For purposes of this Section, the "aggregate limit" for
                        any Plan Year shall mean a percentage equal to the
                        greater of (i) or (ii) below:

                        (i)   The percentage equal to the sum of (A) and (B)
                              below:

                              (A)   125% of the greater of:

                                    (1)   The Actual Deferral Percentage for 
                                          Eligible Employees who are Nonhighly 
                                          Compensated Employees for the Plan 
                                          Year, or

                                    (2)   The Actual Contribution Percentage of 
                                          such Eligible Employees, and

                              (B)    2% plus the lesser of (A)(1) or (A)(2)
                                     above. In no event, however, shall this
                                     percentage exceed 200% of the lesser of
                                     (A)(1) or (A)(2) above.

                        (ii)  The percentage equal to the sum of (A) and (B)
                              below:

                              (A)   125% of the lesser of:

                                    (1)   The Actual Deferral Percentage for 
                                          Eligible Employees who are Nonhighly 
                                          Compensated Employees for the Plan 
                                          Year, or

                                    (2)   The Actual Contribution Percentage of 
                                          such Eligible Employees, and

                               (B)  2% of the greater of (A)(1) or (A)(2) above.
                                    In no event, however, shall this percentage 
                                    exceed 200% of the greater of (A)(1) or 
                                    (A)(2) above.

                        The "aggregate limit" shall be calculated to the nearest
                        one-hundredth of one percent (.01%).

                        The "aggregate limit" shall be applied to reduce
                        allocations otherwise permissible for a Plan Year if
                        after application of paragraph (f) above the sum of the
                        average percentages described in paragraphs (d) and (e)
                        above applicable to the group of Eligible Employees who
                        are Highly

<PAGE>   107
                        Compensated Employees exceeds the "aggregate limit" for
                        such Plan Year.

                        The "aggregate limit" shall not apply to reduce
                        allocations otherwise permissible for a Plan Year unless
                        the Actual Deferral Percentage and the Actual
                        Contribution Percentage for Eligible Employees who are
                        Highly Compensated Employees for the Plan Year each
                        exceed 125% of the corresponding percentages determined
                        for Eligible Employees who are Nonhighly Compensated
                        Employees for the Plan Year.

                        The reduction of the Actual Contribution Percentage
                        and/or Actual Deferral Percentage of the group of
                        Eligible Employees who are Highly Compensated Employees
                        shall be applied to those Highly Compensated Employees
                        who are eligible to make Before-Tax Contributions or
                        Cash Option Deferrals, or are eligible to receive
                        Employer Matching Contributions. Reductions shall be
                        made in the manner described in paragraph (f) above to
                        the extent necessary to comply with the aggregate limit,
                        except that the reductions shall be applied first to
                        reduce Actual Contribution Percentages and then, if
                        necessary, to reduce Actual Deferral Percentages.

                  (h)   The Committee shall maintain sufficient records to
                        demonstrate that the Plan satisfies the
                        nondiscrimination tests described in paragraphs (d), (e)
                        and (g) above".

26.   Effective January 1, 1997, Section 12.6 is amended so that the first
      sentence reads as follows:

            "For purposes of the Plan, the term "leased employee" means any
            person who would not otherwise be considered an Employee but who,
            pursuant to an agreement between the Employer or an Affiliated
            Employer and a leasing organization (within the meaning of Section
            414(n)(2) of the Code) has performed services for the Employer or
            Affiliated Employer on a substantially full time basis for a period
            of at least one year, and such services are performed under the
            direction and control of the Employer or Affiliated Employer."

                             FOURTH AMENDMENT TO THE
                         UST CORP. EMPLOYEE SAVINGS PLAN




WHEREAS, UST Corp. (the "Sponsoring Employer") maintains the UST Corp. Employee
Savings Plan (the "Plan") which was amended and restated effective July 1, 1996
for the benefit of its eligible employees and their beneficiaries; and

WHEREAS, the Sponsoring Employer reserves the right to amend the Plan at any
time in accordance with Section 13.1 of the Plan; and

WHEREAS, the Sponsoring Employer desires to amend the Plan to
a)       recognize a portion of the commissions earned by certain employees, and
b)       enhance the employer matching contribution to be an IRS safe harbor
         formula;

NOW THEREFORE, the Plan is hereby amended effective January 1, 1999 in the
following ways:

1.       Section 1.13 is hereby amended to add the following paragraph
         immediately after the first paragraph thereof:

         "Notwithstanding the foregoing, in the case of an Employee who is
         specifically assigned to a formal commission-based incentive plan as
         either a
a)       Mortgage Originator,
b)       The Investment Group at USTrust sales representative, or
c)       UST Leasing Corp. sales representative,

         Compensation shall be 80% of the sum of base pay plus commissions paid
         to such Employee by an Employer and included in the income reported on
         Federal Income Tax Form W-2. "Commission-based incentive plans" are
         those that provide for variable payments directly related to the sale
         of company services and products, and provide for payment on a
         quarterly or more frequent basis."

2.       Section 4.1 is hereby amended to change the phrase "6% of Compensation"
         to "5% of Compensation" throughout.

3.       Section 5.2 is hereby amended so that the first paragraph reads as
         follows:

         "As of each Valuation Date, an Employer Matching Contribution shall be
         credited to the Employer Matching Contribution Account of each
         Participant who made Basic Before-Tax Contributions to the Trust Fund
         since the previous Valuation Date. The Employer Matching Contributions
         made on behalf of each such


<PAGE>   110

         Participant shall be based upon the Participant's Basic Before-Tax
         Contributions and Compensation since the previous Valuation Date, and
         shall be equal to the sum of (a) 100% of the Participant's Basic
         Before-Tax Contributions which do not exceed 3% of Compensation, plus
         (b) 50% of the Participant's Basic Before-Tax Contributions which
         exceed 3% of Compensation."

4.       Section 12.5 is amended to add the following paragraph to the beginning
         thereof.

         "This Section 12.5 shall only apply to the extent required by law."



IN WITNESS WHEREOF, the Sponsoring Employer has caused this Amendment to be
executed by its duly elected officer this 16th day of December, 1998.

      This Agreement is made by and between UST Corp., a Massachusetts

January, 1999 (the "Effective Date"), amending in part and restating that
certain First Amended and Restated Employment Agreement between the parties
dated as of the 21st day of November, 1995, as amended by the agreement between
the parties dated as of the 2nd day of January, 1997 (collectively, the "First

the parties dated as of the 20th day of April, 1993, as amended on July 13, 1993
and February 15, 1994 (collectively, the "Original Agreement").

      WHEREAS, UST considers the establishment and maintenance of a sound and
vital management to be essential to the protection and enhancement of the best
interests of UST and its shareholders;

      WHEREAS, on the date hereof, the Employee is President, Chief Executive
Officer ("CEO") and a member of the Board of Directors of UST (the "UST Board")
and has developed an intimate and thorough knowledge of UST's business methods
and operations; and

      WHEREAS, the retention of the Employee's services for and on behalf of UST
is material to the preservation and enhancement of the value of UST's business;
and

      WHEREAS, UST wishes to retain the Employee's services, and the Employee
wishes to continue in the employment of UST, on the terms and conditions
contained herein;

      NOW, THEREFORE, in consideration of the foregoing premises and of the
mutual promises, terms, provisions and conditions contained in this Agreement,
the parties agree as follows:

1.    EMPLOYMENT. Subject to the terms and conditions contained in this
Agreement, UST agrees to continue the employment of the Employee, and the
Employee agrees to continue in the service of UST.

2.    TERM. Subject to earlier termination as provided hereafter, the Employee's
employment hereunder shall be for a term of three (3) years, commencing on the
Effective Date, which term may be extended or renewed only by a written
agreement signed by the Employee and a duly authorized representative of UST.
Notwithstanding the foregoing, in

                                       1
<PAGE>   2
                                                                               2

the event that this Agreement is in effect on the date of consummation of a
Change of Control, as defined in Section 5.g.ii below, this Agreement shall
automatically be extended on said date such that the remaining term of the
Agreement shall then be two (2) years, but this Agreement shall be renewable
thereafter only by a written agreement signed by the Employee and a duly
authorized representative of UST. The term of this Agreement, as from time to
time renewed or extended in accordance with this Section 2, is hereafter
referred to as "the term hereof" or "the term of this Agreement."

3.    PERFORMANCE.

      a. During the term hereof, the Employee shall hold the position of
President and CEO of UST, subject to the direction and control of the UST Board.
The Employee shall perform the duties and assume the responsibilities of such
positions and such other appropriate duties and responsibilities as may
reasonably be assigned from time to time by the UST Board or its designee. UST
shall propose to the shareholders of UST at each appropriate Annual Meeting of
such shareholders during the term hereof the reelection of the Employee as a
member of the UST Board, provided that the Employee is otherwise eligible for
such election. In addition, and without further compensation, the Employee shall
serve as a director and/or officer of one or more of the Affiliates and as a
member of committees of the UST Board and the boards of directors of the
Affiliates, if so elected or appointed from time to time.

      b. During employment, the Employee shall devote his full business time and
best efforts, judgment, skill and knowledge exclusively to the advancement of
the interests of UST and the Affiliates and to the discharge of his duties and
responsibilities for them and shall perform all such duties and responsibilities
in good faith and in a manner consistent with banking industry standards. While
employed by UST, the Employee shall not be engaged in any other business
activity, except as approved by the UST Board or its designee in writing. It is
agreed, however, that the provisions of this Section 3.b shall not be violated
by the Employee's holding of directorships or related positions in charitable,
educational or not-for-profit organizations which do not involve continuous or
substantial time commitments or by passive personal investment activities,
provided that such positions and activities are not in conflict, and do not
otherwise interfere, with the Employee's duties and responsibilities to UST and
the Affiliates.

4.    COMPENSATION. As compensation for all services performed for UST and the
Affiliates during the term of this Agreement:

      a. BASE SALARY. During the term hereof, UST shall pay the Employee a base
salary at an annual rate of not less than Six Hundred Thousand Dollars
($600,000), 
<PAGE>   3
                                                                               3

which amount shall be subject to increase from time to time at the discretion of
the UST Board or its designee. The base salary, as adjusted from time to time in
accordance with this Section 4, is hereafter referred to as the "Base Salary."

      b. SHORT TERM INCENTIVE COMPENSATION. The Employee shall be eligible to be
considered for short term incentive compensation with an annual target of not
less than one hundred percent (100%) of the Base Salary for calendar year 1999
and for each full calendar year thereafter during the term hereof. The
determination of whether bonus compensation will be granted and, if so, the
amount of any such bonus shall be determined by the UST Board in its discretion,
based on its assessment of the Employee's performance during the applicable
calendar year and taking into consideration the Employee's total compensation
(including but not limited to the value of the Restricted Stock, as hereafter
defined, granted him) in comparison with that of other chief executive officers
in businesses comparable to UST. The Employee shall not be eligible to
participate in any other bonus plan, program or arrangement of UST during the
term hereof unless expressly so authorized by the UST Board.

      c. STOCK OPTIONS AND RESTRICTED STOCK.

            i. All stock options granted to the Employee under the Original
Agreement and the First Amended Agreement have vested as of the Effective Date.
In addition, on the first business day following the Effective Date (i.e., on
January 4, 1999), UST shall grant to the Employee a non-qualified stock option
to purchase 360,000 shares of UST's Common Stock, which option shall be fully
vested on the date of grant and shall be and remain exercisable for a period of
five years from the date of grant, subject to the terms of UST's Stock
Compensation Plan as amended by UST from time to time (the "Plan") in the event
that the Employee's employment terminates prior to the expiration of the five
year exercise period and the option has not been exercised at the time of such
termination. The exercise price of all shares under said non-qualified stock
option shall be the fair market value on the date of grant. Except as otherwise
expressly provided herein, the option shall be governed by the terms of the
Plan. The Employee shall not otherwise be entitled to be granted stock options
during the period ending December 31, 2001. Any stock options granted the
Employee thereafter shall be at the discretion of the Compensation Committee of
the UST Board.

            ii. Pursuant to the Original Agreement, the Employee has been
granted shares of UST Restricted Common Stock ("Restricted Stock") under the
Plan from which the restrictions have lapsed. Pursuant to the First Amended
Agreement, the Employee has been granted additional shares of Restricted Stock
under the Plan, from certain of which the restrictions have lapsed prior to the
Effective Date and from the 
<PAGE>   4
                                                                               4

remainder of which the restrictions shall lapse on January 4, 1999. On January
4, 1999, UST shall grant the Employee an additional 10,000 shares of Restricted
Stock under the Plan, from approximately one third of which shares the
restrictions shall lapse during the term hereof on each of the date of grant and
the first and second anniversaries of the date of grant. On each of January 4,
2000, and January 4, 2001, during the term hereof, UST shall grant the Employee
an additional 10,000 shares of Restricted Stock under the Plan, from which
shares the restrictions shall lapse as determined in the discretion of the UST
Board or the Compensation Committee thereof. Any additional shares of Restricted
Stock granted the Employee shall be at the discretion of the Compensation
Committee of the UST Board.

      d. EMPLOYEE BENEFIT PLANS. During the term hereof, the Employee shall be
entitled to participate in any and all employee benefit plans from time to time
in effect for employees of UST generally, excluding only plans providing
payments and/or other benefits in the event of termination of employment. Such
participation shall be subject to the terms of the applicable plan documents,
generally applicable UST policies and the discretion of the UST Board or any
administrative or other committee provided for in or contemplated by such plan.

      e. UST EXECUTIVE SERP. Notwithstanding anything to the contrary contained
in the UST Corp. Senior Executive Plan (the "SERP"), for purposes of determining
the Employee's Target Benefit, as that term is defined in Article III of the
SERP, the Employee's Credited Service shall be deemed to be as follows:

                   Age at Termination
                      of Employment       Years of Credited Service
                           62                          9
                           63                         11
                           64                         13
                           65                         15

Notwithstanding the preceding schedule, however, in the event of a Change of
Control and subsequent termination of employment prior to the Employee
attaining age 63, Paragraph 1 of Section 10.07 of the SERP shall govern in
determining Credited Service and assumed age.

UST undertakes to dedicate cash to a trust that will fund the payment of SERP
obligations to the Employee.

      f. EXECUTIVE PERQUISITES. The Employee shall receive an allowance of not
<PAGE>   5
                                                                               5

less than Seven Hundred and Ninety Dollars ($790) per month which he shall use
to defray the cost of the business use of an automobile owned or leased by the
Employee. The Employee's annual dues and reasonable business expenses related to
UST's business at the Bay Club and the Union Club shall be reimbursed by UST.
Unless otherwise provided in this Agreement, the Employee shall be entitled to
participate in all programs and perquisites provided to executives of UST
generally, except to the extent such programs and perquisites are duplicative of
benefits provided to the Employee hereunder.

5. TERMINATION OF EMPLOYMENT. Notwithstanding the provisions of Section 2 above,
the Employee's employment under this Agreement shall terminate under the
following circumstances and, in that event, UST shall have only such obligations
to the Employee as are specified below under the applicable termination
provision of this Section 5:

      a. UPON DEATH. In the event of the Employee's death during the term
hereof, the Employee's employment hereunder shall immediately and automatically
terminate. In such event, UST shall pay to the Employee's designated beneficiary
or, if no beneficiary has been designated by the Employee, to the Employee's
estate, Base Salary earned but unpaid, and vacation time accrued but unused,
through the date of death and any short-term incentive compensation awarded but
unpaid on the date of death.

      b. AS A RESULT OF DISABILITY. In the event that the Employee becomes
disabled during the term hereof and, as a result, is unable to perform
substantially all of his duties for UST for more than one hundred and eighty
(180) days during any period of three hundred and sixty-five (365) days, UST may
terminate the Employee's employment without further obligation upon notice to
the Employee. In the event of such disability, the Employee will continue to
receive the Base Salary and benefits in accordance with Section 4 hereof until
the earlier of (i) the date the Employee becomes eligible for disability income
under UST's long-term disability or workers' compensation insurance plan or (ii)
the date his employment terminates.

      c. BY UST FOR CAUSE. UST may terminate the Employee's employment for Cause
at any time upon notice to the Employee setting forth in reasonable detail the
nature of such Cause. The following shall constitute Cause for termination: (i)
the Employee's willful refusal to perform, or gross malfeasance in the
performance of, his duties or responsibilities on behalf of UST and the
Affiliates; (ii) the Employee's fraud, embezzlement or other material dishonesty
with respect to UST or any of the Affiliates; (iii) the Employee's gross
misconduct or (iv) the Employee's conviction of, or plea of no contest to, a
felony; provided, however, that, in the event of termination under clause (i) or
(iii) hereof, UST will give the Employee notice, in reasonable detail, of the
basis for termination and an opportunity of not more than (10) ten business days
to cure in a manner 
<PAGE>   6
                                                                               6

which reasonably assures UST that such event will not recur. In the event of
termination under this Section 5.c, UST shall have no further obligation to the
Employee, other than for Base Salary earned but unpaid, and vacation time
accrued but unused, through the date of termination and any short-term incentive
compensation awarded but unpaid on the date of termination. Employee's
participation in UST's employee benefit plans shall end as of the date of
termination, but termination shall not result in the loss of any benefits that
have vested under any such plan on or before the date of termination. Stock
options and Restricted Stock shall be governed by the terms of the Plan.

      d. BY UST OTHER THAN FOR CAUSE. UST may terminate the Employee's
employment other than for Cause upon notice to the Employee under this
subsection d or under subsection g below, whichever is applicable. In the event
of such termination prior to, or more than two years following, a Change of
Control and provided that the Employee executes the release of claims attached
hereto and marked "Appendix A" (the "Employee Release") within twenty-one (21)
days of his receipt of notice of termination of employment and does not timely
revoke the Employee Release, UST shall pay the Employee Base Salary earned but
unpaid, and vacation time accrued but unused, through the date of termination
and any short-term incentive compensation awarded but unpaid on the date of
termination and, in addition, UST

            i. shall pay the Employee severance pay in an amount equal to
      twenty-four (24) months' Base Salary at the rate in effect on the date of
      termination of the Employee's employment, which the Employee may elect to
      receive (A) in a single lump sum, payable within thirty (30) days
      following the effective date of the Employee Release or (B) as salary
      continuation payable at UST's regular payroll periods and in accordance
      with its regular payroll practices commencing on the next regular payday
      immediately following the effective date of the Employee Release, but
      retroactive to the date of termination;

            ii. shall pay the Employee an amount equal to two times the
      short-term incentive compensation which the Employee received for the last
      full calendar year immediately preceding the date of termination of his
      employment, payable within thirty (30) days following the effective date
      of the Employee Release;

            iii. shall cause to be vested all unvested stock options to purchase
      UST Common Stock granted to the Employee and not yet exercised, expired,
      surrendered or canceled and shall cause all restrictions to lapse on all
      Restricted Stock held by the Employee; and
<PAGE>   7
                                                                               7

            iv. at the Employee's election, (A) shall continue to pay, for
      twenty-four (24) months following the date of termination of the
      Employee's employment or, if earlier, until the date the Employee is
      covered under another employer's health plan that is comparable to that of
      UST (the "Post-Employment Health Coverage Period"), that share of the
      premium cost of the Employee's participation and that of his eligible
      dependents in UST's group health plan as it pays for active employees of
      UST and their eligible dependents generally OR (B) shall pay the Employee
      a single lump sum payment equal to the amount that UST would have expended
      if participation had been elected and continued for twenty-four (24)
      months following the date of termination of the Employee's employment,
      which lump sum shall be payable within thirty (30) days following the
      effective date of the Employee Release, and the Employee and his eligible
      dependents may exercise any rights they have under Sections 601-607 of
      ERISA and Section 4980B of the Internal Revenue Code (collectively
      referred to as "COBRA") to continue participation in the group health plan
      at their cost, effective as of the date the Employee's employment
      terminates. Should the Employee elect option (A) above, the period of any
      continued health coverage to which the Employee and his eligible
      dependents may be entitled under COBRA as a result of the Employee's
      termination of employment will commence at the end of the above-defined
      Post-Employment Health Coverage Period. Notwithstanding anything to the
      contrary contained herein, the Employee may elect option (A) directly
      above only if the Employee elects to receive payment under Section 5.d.i
      in the form of salary continuation.

      e. BY THE EMPLOYEE FOR GOOD REASON. The Employee may terminate employment
hereunder for Good Reason upon notice to UST setting forth in reasonable detail
the nature of such Good Reason. The following shall constitute Good Reason for
termination by the Employee: (i) failure of UST to continue the Employee in his
position as President and CEO of UST; (ii) a change adverse to the Employee in
the Employee's primary reporting relationship; (iii) material diminution in the
nature or scope of the Employee's responsibilities, duties or authority; (iv)
material failure of UST to provide the Employee compensation and benefits in
accordance with the terms of Section 4 hereof; or (v) a permanent transfer of
the Employee to a work site more than twenty-five (25) miles distant from his
work site on the Effective Date. In the event of termination in accordance with
this Section 5.e, UST shall provide the Employee Base Salary, short-term
incentive compensation, vesting of stock options, lapse of restrictions on
Restricted Stock and health plan benefits in accordance with Section 5.d hereof,
provided that the Employee executes 
<PAGE>   8
                                                                               8

the Employee Release within twenty-one (21) days of his notice of termination of
employment and provided further that the Employee does not timely revoke the
Employee Release.

      f. BY THE EMPLOYEE OTHER THAN FOR GOOD REASON. The Employee may resign
employment other than for Good Reason at any time upon sixty (60) days' notice
to UST. In the event of such termination, UST shall have no further obligation
to the Employee, other than for Base Salary earned but unpaid, and vacation
time accrued but unused, through the date of termination and any short-term
incentive compensation awarded but unpaid on the date of termination.

      g. UPON A CHANGE OF CONTROL.

            i. If, upon a Change of Control (as defined in subsection g.ii
below), the Employee elects to terminate this Agreement by notice to UST or its
successor or if, upon a Change of Control or within two (2) years thereafter,
UST terminates the Employee's employment other than for Cause or the Employee
terminates his employment for Good Reason and if, within twenty-one (21) days of
the date the Employee or UST gives notice of termination of his employment, the
Employee executes the Employee Release and does not timely revoke it thereafter,
then, in lieu of any payment and benefits to which the Employee would otherwise
be entitled under Section 5.d or 5.e hereof, UST shall pay the Employee Base
Salary earned but unpaid, and vacation time accrued but unused, through the date
of termination and any short-term incentive compensation awarded but unpaid on
the date of termination and, in addition, UST shall provide the Employee the
following:

                  (1) UST shall pay the Employee an amount equal to thirty-six
      (36) months' Base Salary at the rate in effect on the date of termination
      of the Employee's employment, which the Employee may elect to receive (A)
      in a single lump sum, payable within thirty (30) days following the
      effective date of the Employee Release or (B) as salary continuation
      payable at UST's regular payroll periods and in accordance with its
      regular payroll practices commencing on the next regular payday following
      the effective date of the Employee Release, but retroactive to the date of
      termination.

                  (2) UST shall pay the Employee an amount equal to three times
      the short-term incentive compensation which the Employee received for the
      last full calendar year immediately preceding the date of termination of
      his employment, payable within thirty (30) days following the effective
      date of the Employee Release.
<PAGE>   9
                                                                               9

                  (3) At the Employee's election, UST (A) shall continue to pay,
      for the period of thirty-six months following termination of the
      Employee's employment or, if earlier, until the date the Employee is
      covered under another employer's health plan that is comparable to that of
      UST (the "Change of Control Post-Employment Health Coverage Period"), that
      share of the premium cost of the Employee's participation and that of his
      eligible dependents in UST's group health plan as it pays for active
      employees of UST and their eligible dependents generally OR (B) shall pay
      the Employee a single lump sum payment equal to the amount that UST would
      have expended if participation had been elected and continued for a period
      of thirty-six (36) months, which lump sum shall be payable within thirty
      (30) days following the effective date of the Employee Release, and the
      Employee and his eligible dependents may exercise their rights under COBRA
      to continue participation in the group health plan at their cost effective
      as of the date his employment terminates. Should the Employee elect option
      (A) above, the period of any continued health coverage to which the
      Employee and his eligible dependents may be entitled under COBRA as a
      result of the Employee's termination of employment will commence at the
      end of the above-defined Change of Control Post-Employment Health Coverage
      Period. Notwithstanding anything to the contrary contained herein, the
      Employee may only elect option (A) directly above if the Employee elects
      to receive payment under Section 5.g.i.(1) in the form of salary
      continuation.

                  (4) Upon a Change of Control as defined in the Plan, the
      vesting of any Restricted Stock or stock options to purchase UST Common
      Stock granted to the Employee and not yet exercised, expired, surrendered
      or canceled shall be in accordance with the Plan.

                  (5) If in connection with a Change of Control as defined in
      the Plan any other employees who hold stock options under the Plan or
      Restricted Stock will have their options or Restricted Stock or both
      cashed out, whether under the Plan or otherwise, the Employee shall have
      the right to have all or any of such options (including any non-qualified
      options granted pursuant to Section 4.c hereof) or Restricted Stock or
      both cashed out on the same basis and at the same time the options and
      Restricted Stock of such other employees are cashed out.

            ii. Except as otherwise provided with respect to subparagraphs
g.i.(4) and g.i.(5) directly above, a "Change of Control" shall be deemed to
have been consummated if hereafter 

                  (A) any "person", as such term used in Section 13(d) and 
<PAGE>   10
                                                                              10

      14(d) of the Securities Exchange Act of 1934 as amended (the "Exchange
      Act"), other than UST or any of the Affiliates or any trustee or other
      fiduciary holding securities under an employee benefit plan of UST or any
      of the Affiliates, becomes a beneficial owner (within the meaning of Rule
      13d-3, as amended, as promulgated under the Exchange Act), directly or
      indirectly, of securities representing twenty-five percent (25%) or more
      of the combined voting power of UST's then outstanding securities; or

                  (B) during any period of two consecutive years (not including
      any period prior to the Effective Date), individuals who at the beginning
      of such period constitute the Board, and any new director [ other than a
      director designated by a person who has entered into an agreement with UST
      to effect a transaction described in clause (A), (C) or (D) of this
      Section 5.g.(ii) ] whose election by the Board or nomination for election
      by UST's stockholders was approved by a vote of at least two-thirds of the
      directors then still in office who either were directors at the beginning
      of the period or whose election or nomination for election was previously
      so approved, cease for any reason to constitute at least a majority
      thereof; or

                  (C) there occurs a merger or consolidation of UST with any
      other corporation, other than a merger or consolidation which would result
      in the voting securities of UST outstanding immediately prior thereto
      continuing to represent (either by remaining outstanding or by being
      converted into voting securities of the surviving entity) more than eighty
      percent (80%) of the combined voting power of the voting securities of UST
      or such surviving entity outstanding immediately after such merger or
      consolidation; provided, however, that a merger or consolidation effected
      to implement a recapitalization of UST (or similar transaction) in which
      no "person" (as hereinabove defined) acquires more than twenty-five
      percent (25%) of the combined voting power of UST's then outstanding
      securities shall not constitute a Change of Control; or

                  (D) the stockholders of UST approve a plan of a complete
      liquidation of UST; or

                  (E) there occurs a closing of a sale or other disposition by
      UST of all or substantially all of its assets.

6. POST-AGREEMENT EMPLOYMENT. In the event the Employee remains in the employ of
UST or any of the Affiliates following termination of this Agreement, by the
expiration of the term or otherwise, then such employment shall be at will.

7. EFFECT OF TERMINATION. Provisions of this Agreement shall survive any
termination of this Agreement, by expiration of the term or otherwise, if so
provided herein or if necessary or desirable fully to accomplish the purposes of
such provision, including without limitation the obligations of the Employee
under Sections 8 and 9 hereof.

8. CONFIDENTIAL INFORMATION. The Employee acknowledges that UST continually
develops Confidential Information, that the Employee may develop Confidential
Information for UST and that the Employee may learn of Confidential Information
during the course of employment. The Employee agrees to comply with the policies
and procedures of UST for protecting Confidential Information and agrees that he
shall never disclose to any person, corporation or other entity, except as
required for the proper performance of his regular duties for UST, and shall
never use for his own benefit or that of another, any Confidential Information
obtained by the Employee incident to his employment or other association with
UST or any of the Affiliates. The Employee understands that this restriction
will continue to apply throughout his employment and after his employment
terminates, regardless of the reason for such termination; provided, however,
that the obligations contained in this Section 8 shall not apply to any
Confidential Information that becomes publicly known through no fault of the
Employee or that the Employee is otherwise required by law or regulation to
disclose.

9. NON-COMPETITION AND NON-SOLICITATION.

      a. In the event the Employee leaves his employment with UST without Good
Reason during the term hereof or is discharged during the term hereof for one or
more of the causes set forth in Section 5.c hereof, the Employee agrees that he
shall not enter into the employment of any other financial institution or entity
in the Eastern Massachusetts banking market (as defined by the Federal Reserve
Bank of Boston) having assets in excess of $1 billion for the period of two (2)
years immediately following the date of termination of his employment.

      b. The Employee further agrees that for a period of two (2) years
following termination of his employment pursuant to Section 5 c. or 5 f hereof,
he will not directly or indirectly, for his own account or for the account of
others, (i) solicit the business of persons whom he knows to be customers of UST
or any of the Affiliates with regard to the provision of any type of financial
service provided by UST or any of the Affiliates or (ii) after notice from UST
that any one or more persons or entities are customers, commence or continue the
solicitation of such business from any such person or entity or (iii) solicit or
hire executive personnel of UST or any of the Affiliates for the benefit of any
entity controlled by the Employee or by which the Employee is employed or from
which the

                                                                              12

Employee receives any form of fee or compensation.

10. REMEDIES. The Employee acknowledges that, if he were to breach any of the
provisions of Section 8 or Section 9 of this Agreement, the harm to UST would be
irreparable. The Employee therefore agrees that, in addition to any other
remedies available to it, UST shall be entitled to obtain preliminary and
permanent injunctive relief against any such breach, without having to post
bond.

11. TAXES. All payments made to the Employee under this Agreement shall be
reduced by any tax or other amount required to be withheld by UST under any
applicable withholding law.

12. REDUCTIONS. Notwithstanding anything to the contrary contained in this
Agreement, the payments and benefits to which the Employee would be entitled
pursuant to Section 5.g hereof or otherwise as a result of a Change of Control
shall be reduced to the maximum amount for which UST will not be limited in its
deduction pursuant to Section 280G of the Internal Revenue Code of 1986, as
amended, or any successor provision. Any such reduction shall be applied to the
amounts due to the Employee in such manner as the Employee may reasonably
specify within thirty (30) days following notice from UST of the need for such
reduction or, if the Employee fails to so specify timely, as determined by UST.

13. ASSIGNMENT. UST may assign its rights and obligations under this Agreement
without the consent of the Employee in the event that UST shall hereafter effect
a reorganization, consolidate with, or merge into, any other person, corporation
or other entity or transfer all or substantially all of its assets to any other
person, corporation or other entity. UST requires the personal services of the
Employee and he may not assign this Agreement. This Agreement shall inure to the
benefit of and be binding upon UST and the Employee and their respective
successors, executors, administrators, heirs and permitted assigns.

14. INDEMNIFICATION. UST shall, and UST shall use its best efforts to cause the
Affiliates to, indemnify the Employee to the maximum extent permitted by law and
regulation in connection with any liability, expense or damage which the
Employee incurs or to which the Employee is exposed as a result of the
Employee's employment and positions with UST and the Affiliates as contemplated
by this Agreement, provided that the Employee shall not be indemnified with
respect to any matter as to which he shall have been adjudicated in any
proceeding not to have acted in good faith in the reasonable belief that his
action was in the best interest of UST and the Affiliates. UST, on behalf of
itself and the Affiliates, hereby confirms that the occupancy of all offices and
positions which in 
<PAGE>   13
                                                                              13

held at the request of and for the benefit of UST and the Affiliates for
purposes of the Employee's entitlement to indemnification under applicable
provisions of the respective articles of organization and/or other similar
documents of UST and the Affiliates.

                                RELEASE OF CLAIMS

      FOR AND IN CONSIDERATION OF the special payments to be made to me in
connection with my separation of employment, as set forth in the Second Amended
and Restated Executive Employment Agreement between UST Corp. and me dated as of
the 1st day of January, 1999 (the "Employment Agreement"), I, on my own behalf
and on behalf of my heirs, beneficiaries and representatives and all others
connected with me, hereby release and forever discharge UST Corp. ("UST"), the
Affiliates (as defined in the Employment Agreement), and all of their respective
officers, directors, employees, agents, representatives, successors and assigns
(all collectively, the "Released"), both individually and in their official
capacities, from any and all liabilities, claims, demands, actions and causes of
action of any type (all collectively "Claims") which I have had in the past, now
have, or might now have, through the date of my execution of this Release of
Claims, in any way resulting from, arising out of or connected with my
employment or its termination or pursuant to any federal, state or local
employment law, regulation or other requirement (including without limitation
Title VII of the Civil Rights Act of 1964, as amended, the Age Discrimination in
Employment Act, as amended, the Americans with Disabilities Act, as amended, and
the Massachusetts fair employment practices act, as amended).

      Excluded from the scope of this Release of Claims is (i) any claim arising
hereafter under the terms of the Employment Agreement or under the terms of any
of UST's employee qualified and non-qualified benefit plans (including without
limitation UST's employee pension plan, profit sharing plan or stock ownership
plan) and (ii) any right of indemnification or contribution pursuant to the
Articles of Organization or By-Laws of UST that I have or hereafter acquire if
any claim is asserted or proceedings are brought against me by any governmental
or regulatory agency, or by any customer, creditor, employee or shareholder of
UST or any other person or entity, or by any self-regulatory organization, stock
exchange or the like, related or allegedly related to my having been an officer
or employee of UST or to any of my activities as an officer or employee of UST.

      By acceptance of or reliance on this Release of Claims, UST promises that
neither it nor any of the other Released who are Affiliates of UST will take any
action that is designed, specifically as to me or with respect to a class of
similarly situated former employees, to reduce or abrogate, or may reasonably be
expected to result in an abridgment or elimination of, any rights under any
policy or policies of directors and officers liability insurance affording
coverage to former officers and in effect from time to time, unless any such
abridgment or elimination of rights is also generally applicable to then-current
officers and employees of UST.

      In signing this Release of Claims, I acknowledge that I have had at least
twenty-one (21) days from the date of my receipt of notice of termination of my
employment (or, if applicable, the date I gave such notice to UST) to consider
the terms of this Release of Claims, that I am encouraged by UST to seek the
advice of an attorney prior to signing this Release of Claims and that I am
signing this Release of Claims voluntarily and with a full understanding of its

                                                               EXHIBIT 10(i)(ii)

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Executive Employment Agreement (hereafter referred to as this
"Agreement") is made by and between UST Corp., a Massachusetts corporation, (the
"Company") and Timothy J. Hansberry (the "Employee") as of the 10th day of
August, 1998 (the "Effective Date").

         In consideration of the mutual promises, terms and conditions contained
in this Agreement, the parties agree as follows:

         1. EMPLOYMENT. The Company agrees to employ the Employee, and the
Employee agrees to accept employment, subject to the terms and conditions
contained in this Agreement.

         2. TERM. Subject to earlier termination, as provided hereafter, the
Employee's employment hereunder shall be for an initial term commencing on the
Effective Date and ending on January 4, 2000 (the "Initial Term"), and shall
automatically renew thereafter for a first renewal term which shall expire on
August 9, 2001; provided, however, that the Company, at its option, may elect to
extend the first renewal term beyond August 9, 2001 to the expiration date of
any employment agreement between the Company and Mr. Neal F. Finnegan with an
effective date on or about January 5, 2000. Upon the expiration of the first
renewal term of this Agreement, this Agreement shall automatically renew
thereafter for successive terms of one year each, unless either party gives
notice to the other at least sixty (60) days prior to the expiration of the
first renewal term or any subsequent renewal term that this Agreement shall not
renew. Notwithstanding the foregoing, in the event that this Agreement is in
effect on the date of consummation of a Change of Control, as defined in Section
5.g.ii below, this Agreement shall automatically be extended on said date such
that the remaining term of the Agreement shall then be two (2) years and, upon
the expiration of that extension, shall thereafter resume automatic renew for
successive terms of one year each, unless either party gives notice to the other
at least sixty (60) days prior to the expiration of the extension or any
subsequent renewal term that this Agreement shall not renew. The term of this
Agreement, as from time to time renewed or extended in accordance with this
Section 2, is hereafter referred to as "the term hereof" or "the term of this
Agreement."

         3. PERFORMANCE.

                  a. During the term hereof, the Employee shall serve the
Company as its Vice Chairman and Chief Operating Officer and as President and
Chief Operating Officer of USTrust and, if so elected or appointed from time to
time, shall also serve as a director of the Company or as a director or officer
of one or more of the Company's Affiliates, as defined in Section 15, below. The
Employee shall perform the duties and assume the responsibilities of such
positions and such other appropriate duties and responsibilities as may be
assigned by the Board of Directors of the Company (the "Board") or its
designees. All such services shall be rendered by the Employee in good faith and
in a manner consistent with banking industry standards.
<PAGE>   2
                  b. During employment, the Employee shall devote his full
business time and best efforts, judgment, skill and knowledge exclusively to the
advancement of the interests of the Company, USTrust and any other Affiliates of
the Company with which he holds a position or office and to the discharge of his
duties and responsibilities for those entities. While employed by the Company or
any of its Affiliates, the Employee shall not be engaged in any other business
activity, except with the written approval of the Board or its designee or of
the President of the Company. It is agreed, however, that the provisions of this
Section 3.b shall not be violated by the Employee's holding of directorships or
related positions in charitable, educational or not-for-profit organizations
which do not involve continuous or substantial time commitments or by passive
personal investment activities, provided that such positions and activities are
not in conflict, and do not otherwise interfere, with the Employee's duties and
responsibilities to the Company, USTrust or any of the Company's other
Affiliates.

         4. COMPENSATION.

                  a. BASE SALARY. As compensation for all services performed for
the Company and its Affiliates during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate of not less than Three
Hundred and Twenty-Five Thousand Dollars ($325,000), subject to increase from
time to time by the Company in its discretion. The Employee's base salary, as
from time to time increased, is hereafter termed the "Base Salary."

                  b. BONUS. During the term hereof, the Employee shall be
eligible to participate in the Company's annual incentive plan for executives,
as in effect from time to time, in accordance with its terms. The Employee shall
not be eligible to participate in any other bonus plan, program or arrangement
of the Company or USTrust during the term hereof unless expressly so authorized
by the Board.

                  c. AUTOMOBILE ALLOWANCE. The Employee shall receive an
allowance of Seven Hundred and Ninety Dollars ($790) per month which he shall
use to defray the costs of the business use of an automobile owned or leased by
the Employee.

                  d. DUES AND EXPENSES. The Employee's annual dues and
reasonable business expenses related to business of the Company, USTrust and the
Company's other Affiliates at the Harvard Club and the Union Club shall also be
reimbursed by the Company.

                  e. STOCK OPTIONS. The Employee shall be granted restricted
stock and stock options in accordance with the vote of the Compensation
Committee of the Board on May 19, 1998, which grant shall be subject to an
agreement between the Employee and the Company on terms comparable to those
generally offered to executive officers of the Company in connection with the
grant of restricted stock and/or stock options (the "Stock Compensation
Agreement") and the Company's Stock Compensation Plan, as amended by the Company
from time to time (the "Stock Compensation Plan").

                  f. EMPLOYEE BENEFITS. During the term hereof, the Employee
shall be entitled 


                                      -2-
<PAGE>   3
to participate in any and all employee benefit plans from time to time in effect
for employees of the Company generally or for executive officers of the Company
generally, including without limitation the Company's Supplemental Retirement
Benefits Plan(s), but excluding plans providing payments and/or other benefits
in the event of termination of employment. Such participation shall be subject
to the terms of the applicable plan documents, generally applicable Company
policies and the discretion of the Board or any administrative or other
committee provided for in or contemplated by such plan.

         5. TERMINATION OF EMPLOYMENT. Notwithstanding the provisions of Section
2 above, the Employee's employment under this Agreement shall terminate under
the following circumstances and, in that event, the Company shall have only such
obligations to the Employee as are specified below under the applicable
termination provision:

                  a. UPON DEATH. In the event of the Employee's death during the
term hereof, the Employee's employment hereunder shall immediately and
automatically terminate. In such event, the Company shall pay to the Employee's
designated beneficiary or, if no beneficiary has been designated by the
Employee, to the Employee's estate, Base Salary earned but unpaid through the
date of termination, any bonus awarded but not yet paid and pay for any vacation
time accrued but not used through the date of termination. .

                  b. AS A RESULT OF DISABILITY. In the event that the Employee
becomes disabled during the term hereof and, as a result, is unable to perform
substantially all of his/her duties for the Company for more than one hundred
and eighty (180) days during any period of three hundred and sixty-five (365)
days, the Company may terminate the Employee's employment without further
obligation upon notice to the Employee. In the event of such disability, the
Employee will continue to receive the Base Salary and benefits in accordance
with Section 4 hereof until the earlier of the date the Employee becomes
eligible for disability income under the Company's long-term disability or
workers' compensation insurance plan or the date his employment terminates.

                  c. BY THE COMPANY FOR CAUSE. The Company may terminate the
Employee's employment for Cause at any time upon notice to the Employee. The
following, as determined by the Board in its reasonable judgment, shall
constitute Cause for termination: (i) the Employee's willful failure to perform,
or gross negligence in the performance of, his duties or responsibilities on
behalf of the Company, USTrust and, as applicable, other Affiliates of the
Company; (ii) the Employee's willful violation of any provision of federal or
state banking or securities law; (iii) the Employee's gross misconduct; (iv) the
Employee's fraud, embezzlement or other material dishonesty with respect to the
Company, USTrust or any of the Company's other Affiliates or (v) his conviction
of, or plea of no contest to, a felony; provided, however, in the event of Cause
arising under clause (i), (ii) or (iii) of this Section 5.c, that the Company
has given the Employee notice, setting forth in reasonable detail the nature of
such Cause, and ten business days' opportunity to cure and the Employee has
failed to effect a cure within that ten-day period in a manner which reasonably
assures the Company that such Cause will not recur. In the event of termination
hereunder, the Company shall have no further obligation to the Employee, other
than 


                                      -3-
<PAGE>   4
for Base Salary earned but unpaid through the date of termination, any bonus
awarded but not yet paid and pay for any vacation time accrued but not used
through the date of termination.

                  d. BY THE COMPANY OTHER THAN FOR CAUSE. The Company may
terminate the Employee's employment other than for Cause upon notice to the
Employee under this subsection d or under subsection g below, whichever is
applicable. In the event of such termination prior to, or more than two years
following, a Change of Control and provided that the Employee executes the
release of claims attached hereto and marked "A" (the "Employee Release") within
twenty-one (21) days of his receipt of notice of termination of employment and
does not timely revoke the Employee Release, the Company:

                  i. shall pay the Employee severance pay in an amount equal to
         eighteen (18) months' Base Salary at the rate in effect on the date of
         termination, which the Employee may elect to receive (A) in a single
         lump sum, payable within thirty (30) days following the effective date
         of the Employee Release or (B) as salary continuation payable at the
         Company's regular payroll periods and in accordance with its regular
         payroll practices commencing on the next regular payday immediately
         following the effective date of the Employee Release, but retroactive
         to the date of termination and,

                  ii. at the Employee's election, (A) shall continue to pay, for
         the period of eighteen (18) months following termination of the
         Employee's employment or, if earlier, until the date the Employee is
         covered under another employer's health plan that is comparable to that
         of the Company (the "Post-Employment Health Coverage Period"), that
         share of the premium cost of Employee's participation and that of his
         eligible dependents in the Company's group health plan as it pays for
         active employees of the Company and their eligible dependents generally
         OR (B) shall pay the Employee a single lump sum payment equal to the
         amount that the Company would have expended if participation had been
         elected and continued for a period of eighteen (18) months, which lump
         sum shall be payable within thirty (30) days following the effective
         date of the Employee Release, and the Employee and his eligible
         dependents may exercise any rights they have under Sections 601-607 of
         ERISA and Section 4980B of the Internal Revenue Code (collectively
         referred to as "COBRA") to continue participation in the group health
         plan at their cost, effective as of the date the Employee's employment
         terminates. Should the Employee elect option (A) above, the period of
         any continued health coverage to which the Employee and his eligible
         dependents may be entitled COBRA as a result of the Employee's
         termination of employment will commence at the end of the above-defined
         Post-Employment Health Coverage Period. Notwithstanding anything to the
         contrary contained herein, the Employee may elect option (A) directly
         above only if the Employee elects to receive payment under Section
         5.d.i., above, in the form of salary continuation and,

                  iii. in addition to the above, shall pay the Employee any Base
         Salary earned but unpaid through the date of termination, any bonus
         awarded but not yet paid and pay for any vacation time accrued but used
         through the date of termination.

<PAGE>   5
                  e. BY THE EMPLOYEE FOR GOOD REASON. The Employee may terminate
employment hereunder for Good Reason upon notice to the Company setting forth in
reasonable detail the nature of such Good Reason. The following shall constitute
Good Reason for termination by the Employee: (i) failure of the Company to
continue the Employee in his position as the Company's Vice Chairman and Chief
Operating Officer and as President and Chief Operating Officer of USTrust; (ii)
a change adverse to the Employee in the Employee's primary reporting
relationship; (iii) material diminution in the nature or scope of the Employee's
responsibilities, duties or authority; (iv) material failure of the Company to
provide the Employee Base Salary and benefits in accordance with the terms of
Section 4 hereof; or (v) a permanent transfer of the Employee to a work site
more than twenty-five miles distant from his work site immediately following the
Effective Date. In the event of termination in accordance with this Section 5.e,
the Company shall provide the Employee Base Salary and health plan benefits in
accordance with Section 5.d hereof, provided that the Employee executes the
Employee Release within twenty-one (21) days of his notice of termination of
employment and provided further that the Employee does not timely revoke the
Employee Release. In addition to the payments and benefits to be provided the
Employee in accordance with this Section 5.e, the Employee shall be entitled to
receive Base Salary earned but unpaid through the date of termination, any bonus
awarded but not yet paid and pay for any vacation time accrued but used through
the date of termination.

                  f. BY THE EMPLOYEE OTHER THAN FOR GOOD REASON. The Employee
may resign employment other than for Good Reason at any time upon ninety (90)
days' notice to the Company. In the event of such termination, the Company shall
have no further obligation to the Employee, other than for Base Salary earned
but unpaid through the date of termination, any bonus awarded but not yet paid
and pay for any vacation time accrued but not used as of the date of
termination.

                  g. UPON A CHANGE OF CONTROL.

                           i. Upon a Change of Control, as defined in Section
5.g.ii, below, the Employee shall be entitled to terminate this Agreement by
notice to the Company or its successor, and in such event, and provided the
Employee executes the Employee Release within twenty-one (21) days of the date
he gives notice of termination of his employment and does not timely revoke it,
the Employee shall be entitled to pay and benefits in accordance with Section
5.g.ii below.

                           ii. If a Change of Control occurs and (A) the
successor to the Company does not expressly assume the Company's obligations
under this Agreement or (B) within two (2) years following such Change of
Control, the Company terminates the Employee's employment other than for Cause,
or the Employee terminates his employment for Good Reason, and, in any such
event, the Employee executes the Employee Release within twenty-one (21) days of
the date of notice of termination of his employment and does not 


                                      -5-

timely revoke it, then, in lieu of any payment or other benefits to which the
Employee would otherwise be entitled under Section 5.d or 5.e hereof, the
Company

                                    (1) shall provide the Employee a cash
         severance payment equal to 2.99 times his "base amount" as defined in
         Section 280G(b)(3) of the Internal Revenue Code of 1986, as amended,
         exclusive of his W-2 earnings resulting from the exercise of stock
         options, which cash severance payment shall be payable in one lump sum
         within five (5) business days following the effective date of the
         Employee Release and,

                                    (2) at the Employee's election, (A) shall
         continue to pay, during the Post-Employment Health Coverage Period,
         that share of the premium cost of Employee's participation and that of
         his eligible dependents in the Company's group health plan as it pays
         for active employees of the Company and their eligible dependents
         generally OR (B) shall pay the Employee a single lump sum payment equal
         to the amount that the Company would have expended if participation had
         been elected and continued for a period of eighteen (18) months, which
         lump sum shall be payable within thirty (30) business days following
         the effective date of the Employee Release, and the Employee and his
         eligible dependents may exercise their rights under COBRA to continue
         participation in the group health plan at their cost effective as of
         the date his employment terminates. Should the Employee elect option
         (A) above, the period of any continued health coverage to which the
         Employee and his eligible dependents may be entitled under COBRA as a
         result of the Employee's termination of employment will commence on the
         date immediately following termination of his employment.

                                    (3) Upon a Change of Control as defined in
         the Company's Stock Compensation Plan as amended by the Company from
         time to time, the vesting of any Company Restricted Common Stock
         ("Restricted Stock") or stock options to purchase Company Common Stock
         granted to the Employee and not yet exercised, expired, surrendered or
         canceled shall be in accordance with the Stock Compensation Plan.

                                    (4) If in connection with a Change of
         Control as defined in the Stock Compensation Plan any other employees
         who hold stock options under that Plan or Restricted Stock will have
         their options or Restricted Stock or both cashed out, whether under the
         Stock Compensation Plan or otherwise, the Employee shall have the right
         to have all or any of his options or Restricted Stock or both cashed
         out on the same basis and at the same time the options and Restricted
         Stock of such other employees are cashed out.

                                    (5) In addition to the payments and/or
         benefits to be provided the Employee under Subsections (1) and (2) of
         this Section 5.g.ii, the Employee shall be entitled to receive Base
         Salary earned but unpaid through the date of termination, any bonus
         awarded but not yet paid and pay for any vacation time accrued but used
         through                                      -6-

 the date of termination.

                           iii. Except as otherwise provided with respect to
subparagraphs g.ii.(3) and g.ii.(4) directly above, a "Change of Control" shall
be deemed to have been consummated if hereafter

                                    (A) any "person", as such term used in
         Section 13(d) and 14(d) of the Securities Exchange Act of 1934 as
         amended (the "Exchange Act") other than the Company or any of its
         Affiliates or any trustee or other fiduciary holding securities under
         an employee benefit plan of the Company or any of its Affiliates,
         becomes a beneficial owner (within the meaning of Rule 13d-3, as
         amended, as promulgated under the Exchange Act), directly or
         indirectly, of securities representing twenty-five (25%) percent or
         more of the combined voting power of the Company's then outstanding
         securities; or

                                    (B) during any period of two consecutive
         years (not including any period prior to the Effective Date),
         individuals who at the beginning of such period constitute the Board,
         and any new director [other than a director designated by a person who
         has entered into an agreement with the Company to effect a transaction
         described in clause (A), (C) or (D) of this Section 6.g.iii] whose
         election by the Board or nomination for election by the Company's
         stockholders was approved by a vote of at least two-thirds of the
         directors then still in office who either were directors at the
         beginning of the period or whose election or nomination for election
         was previously so approved, cease for any reason to constitute at least
         a majority thereof; or

                                    (C) there occurs a merger or consolidation
         of the Company with any other corporation, other than a merger or
         consolidation which would result in the voting securities of the
         Company outstanding immediately prior thereto continuing to represent
         (either by remaining outstanding or by being converted into voting
         securities of the surviving entity) more than eighty percent (80%) of
         the combined voting power of the voting securities of the Company or
         such surviving entity outstanding immediately after such merger or
         consolidation; provided, however, that a merger or consolidation
         effected to implement a recapitalization of the Company (or similar
         transaction) in which no "person" (as hereinabove defined) acquires
         more than twenty-five percent (25%) of the combined voting power of the
         Company's then outstanding securities shall not constitute a Change of
         Control; or

                                    (D) the stockholders of the Company approve
         a plan of a complete liquidation of the Company; or

                                    (E) there occurs a closing of a sale or
         other disposition by the Company of all or substantially all of the
         Company's assets.

                  h. UPON EXPIRATION OF THE TERM HEREOF. Notice by the Company

                                      -7-
<PAGE>   8
pursuant to Section 2 hereof that this Agreement shall not renew shall be
treated as termination by the Company other than for Cause pursuant to Section
5.d. Notice by the Employee pursuant to Section 2 hereof that this Agreement
shall not renew shall be treated as a termination by the Employee of his/her
employment other than for Good Reason.

         6. CONFIDENTIAL INFORMATION. The Employee acknowledges that the Company
and its Affiliates continually develops Confidential Information, as defined in
Section 15 below, that the Employee may develop Confidential Information for the
Company and its Affiliates and that the Employee may learn of Confidential
Information during the course of employment. The Employee agrees to comply with
the policies and procedures of the Company and USTrust for protecting
Confidential Information and agrees that he shall never disclose to any person,
corporation or other entity, except as required for the proper performance of
his regular duties for the Company, USTrust and the Company's other Affiliates,
and shall never use for his own benefit or that of another, any Confidential
Information obtained by the Employee incident to his employment or other
association with the Company, USTrust or any of the Company's other Affiliates.
The Employee understands that this restriction will continue to apply throughout
his employment and after his employment terminates, regardless of the reason for
such termination; provided, however, that the obligations contained in this
Section 6 shall not apply to any Confidential Information that becomes publicly
known through no fault of the Employee and shall not prevent the Employee from
disclosing Confidential Information as required by law or regulation.

         7. NON-COMPETITION. The Employee agrees that, in the event that he
leaves his employment without Good Reason during the term hereof or is
discharged during the term hereof for Cause, he will not enter into the
employment of any other financial institution or entity in Eastern Massachusetts
(as defined by the Federal Reserve Bank of Boston) having assets in excess of $1
billion for a period equal to the balance of the term provided for herein or for
a period of six months, whichever is greater. The Employee further agrees that,
for a period of two years following such termination of his employment, he will
not directly or indirectly, for his own account or for the account of others,
(i) solicit the business of persons or entities whom he knows to be customers of
the Company or any of its Affiliates with regard to the provision of any type of
financial service provided by the Company or any of its Affiliates or (ii) after
notice from the Company that any person or entity is a customer, commence or
continue the solicitation of such business from such person or entity or (iii)
solicit or hire executive personnel of the Company or any of its Affiliates for
the benefit of any entity controlled by the Employee or by which the Employee is
employed or from which the Employee receives any form of fee or compensation.

         8. REMEDIES. The Employee acknowledges that, if he were to breach any
of the provisions of Section 6 or Section 7 of this Agreement, the harm to the
Company and its Affiliates would be irreparable. The Employee therefore agrees
that, in addition to any other remedies available to it, the Company and its
Affiliates shall be entitled to obtain preliminary and permanent injunctive
relief against any such breach, without having to post bond, and to 


                                      -8-
<PAGE>   9
recover any and all costs and expenses incurred in enforcing this Agreement. In
the event that any provision of Section 6 or Section 7 hereof shall be
determined by any court of competent jurisdiction to be unenforceable by reason
of its being extended over too great a time, too large a geographic area or too
great a range of activities, such provision shall be deemed to be modified to
permit its enforcement to the maximum extent permitted by law.

         9. TAXES. All payments made to the Employee under this Agreement shall
be reduced by any tax or other amount required to be withheld by the Company
under applicable law.

         10. REDUCTIONS. Notwithstanding anything to the contrary contained in
this Agreement, (a) any and all payments and benefits to be provided to the
Employee hereunder are subject to reduction to the extent required by applicable
statutes, regulations, rules and directives of federal, state and other
governmental and regulatory bodies having jurisdiction over the Company and/or
any of its Affiliates and (b) the payments and benefits to which the Employee
would be entitled pursuant to Section 5.g hereof or otherwise as a result of a
Change of Control shall be reduced to the maximum amount for which the Company
will not be limited in its deduction pursuant to Section 280G of the Internal
Revenue Code of 1986, as amended, or any successor provision. Any such reduction
shall be applied to the amounts due to the Employee in such manner as the
Employee may reasonably specify within thirty (30) days following notice from
the Company of the need for such reduction or, if the Employee fails to so
specify timely, as determined by the Company.

         11. NO CONFLICTING AGREEMENT. The Employee hereby represents and
warrants to the Company that he is under no contract, agreement or obligation
which (i) prohibits him from entering into this Agreement, (ii) conflicts with
the terms of this Agreement or (iii) prevents him, in any way, from performing
the duties contemplated hereby.

         12. SEVERABILITY. If any portion or provision of this Agreement shall
to any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

         13. ASSIGNMENT. The Company may assign its rights and obligations under
this Agreement without the consent of the Employee in the event that the Company
shall hereafter effect a reorganization, consolidate with, or merge into, any
other person, corporation or other entity or transfer all or substantially all
of its assets to any other person, corporation or other entity. The Company
requires the personal services of the Employee and he may not assign this
Agreement. This Agreement shall inure to the benefit of and be binding upon the
Company and the Employee and their respective successors, executors,
administrators, heirs and permitted assigns.

         14. INDEMNIFICATION. The Company shall, and the Company shall use its
best efforts to cause its Affiliates to, indemnify the Employee to the maximum
extent permitted by law and regulation in connection with any liability, expense
or damage which the Employee incurs or to which the Employee is exposed as a
result of the Employee's employment and positions with the Company and its
Affiliates as contemplated by this Agreement, provided that the Employee shall
not be indemnified with respect to any matter as to which he shall have been
adjudicated in any proceeding not to have acted in good faith in the reasonable
belief that his action was in the best interest of the Company and its
Affiliates. The Company, on behalf of itself and its Affiliates, hereby confirms
that the occupancy of all offices and positions which are occupied or held by
the Employee, now or hereafter, have been so occupied or held at the request of
and for the benefit of the Company and its Affiliates for purposes of the
Employee's entitlement to indemnification under applicable provisions of the
respective articles of organization and/or other similar documents of the
Company and its Affiliates.

         15. DEFINITIONS. As used in this Agreement:

         "Affiliates" means all persons and entities directly or indirectly
controlling, controlled by or under common control with the Company, where
control may be by management authority, equity interest or otherwise.

         "Confidential Information" means any and all information of the Company

its Affiliates has business relationships and the substance of those
relationships. Confidential Information also includes any information received
by the Company or any of its Affiliates from customers or others with any
understanding, express or implied, that it will not be disclosed.

         16. MISCELLANEOUS. This Agreement sets forth the entire agreement
between the Company and the Employee and supersedes all prior communications,
agreements and understandings, whether written or oral, with respect to the
Employee's employment and all matters related thereto, including without
limitation the agreement between the Employee and Affiliated Community Bancorp,

                                RELEASE OF CLAIMS

         FOR AND IN CONSIDERATION OF the special payments to be made to me in
connection with my separation of employment, as set forth in the employment
agreement between UST Corp and me dated as of the 10th day of August, 1998 (the
"Employment Agreement"), I, on my own behalf and on behalf of my heirs,
beneficiaries and representatives and all others connected with me, hereby
release and forever discharge UST Corp. (the "Company"), its Affiliates (as that
term is defined in Section 15 of the Employment Agreement), and all of their
respective officers, directors, shareholders, employees, agents,
representatives, successors and assigns and all others connected with them (all
collectively, the "Released"), both individually and in their official
capacities, from any and all liabilities, claims, demands, actions and causes of
action of any type (all collectively "Claims") which I have had in the past, now
have, or might now have, through the date of my execution of this Release of
Claims, in any way resulting from, arising out of or connected with my
employment or its termination or pursuant to any federal, state or local
employment law, regulation or other requirement (including without limitation
Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment
Act, the Americans with Disabilities Act and the Massachusetts fair employment
practices act, each as may be amended).

         Excluded from the scope of this Release of Claims is (i) any claim
arising hereafter under the terms of the Employment Agreement or under the terms
of any of the Company's qualified and non-qualified employee benefit plans
(including without limitation the Company's employee pension plan, profit
sharing plan or stock ownership plan) and (ii) any right of indemnification or
contribution pursuant to the Articles of Organization or By-Laws of the Company
that I have or hereafter acquire if any claim is asserted or proceedings are

having been an officer or employee of the Company or to any of my activities as
an officer or employee of the Company.

         By acceptance of or reliance on this Release of Claims, the Company
promises that neither it nor any of the other Released affiliated with the
Company will taken any action that is designed, specifically as to me or with
respect to a class of similarly situated former employees, to reduce or
abrogate, or may reasonably be expected to result in an abridgement or
elimination of, any rights of indemnification or contribution available to me
pursuant to the Articles of Organization or By-Laws of the Company, or under any
policy or policies of directors and officers liability insurance affording
coverage to former officers and in effect from time to time, unless any such
abridgement or elimination of rights is also generally applicable to
then-current officers and employees of the Company.

         In signing this Release of Claims, I acknowledge that I have had at
least twenty-one


                                      -12-

(or, if applicable, the date I gave such notice to the Company) to consider the
terms of this Release of Claims, that I am encouraged by the Company to seek the
advice of an attorney prior to signing this Release of Claims and that I am
signing this Release of Claims voluntarily and with a full understanding of its
terms. I understand that I may revoke this Release of Claims at any time within
seven (7) days of the date of my signing by written notice to the President of
the Company and that this Release of Claims will take effect only upon the

                                                              EXHIBIT 10(i)(vii)


                         EXECUTIVE EMPLOYMENT AGREEMENT


      This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company" or "UST") and John Fallon (the "Employee") as of the
10th day of August, 1998 (the "Effective Date").

      In consideration of the mutual promises, terms and conditions contained in
this Agreement, the parties agree as follows:

      1. EMPLOYMENT. The Company hereby offers, and the Employee hereby accepts,
employment with the Company, subject to the terms and conditions contained in
this Agreement.

      2. TERM. Subject to earlier termination, as provided hereafter, the
Employee's employment hereunder shall be for an initial term of two (2) years,
commencing on the Effective Date, which term shall automatically renew
thereafter for successive terms of one year each unless either party gives
notice to the other at least sixty (60) days prior to the expiration of the
initial or any renewal term that this Agreement shall not renew. Notwithstanding
the foregoing, in the event that this Agreement is in effect on the date of
consummation of a Change of Control, as defined in Section 6.g.ii below, this
Agreement shall automatically be extended on said date such that the remaining
term of the Agreement shall then be two (2) years, but this Agreement shall be
renewable thereafter only by a written agreement signed by the Employee and a
duly authorized representative of the Company. The term of this Agreement, as
from time to time renewed or extended in accordance with this Section 2, is
hereafter referred to as "the term hereof" or "the term of this Agreement".

      3.    PERFORMANCE.

            a. During the term hereof, the Employee shall hold the position of
an Executive Vice President of the Company and/or such other executive position
or positions with the Company, its subsidiaries and other affiliates to which
the parties may hereafter from time to time agree and the Employee shall perform
the duties and assume the responsibilities of such positions and such other
appropriate duties and responsibilities as may be assigned by the Board of
Directors of the Company (the"Board") or its designees.

            b. During employment, the Employee shall devote his full business
time and best efforts, judgment, skill and knowledge exclusively to the
advancement of the interests of the Company, its subsidiaries and other
affiliates and to the discharge of his duties and responsibilities for them.
While employed by the Company, the Employee shall not be engaged in any other
business activity, except as approved by the Board, the President or the Board's
designee in writing. It is agreed, however, that the provisions of this Section
3.b shall 


                                       1
<PAGE>   2

not be violated by the Employee's holding of directorships or related
positions in charitable, educational or not-for-profit organizations which do
not involve continuous or substantial time commitments or by passive personal
investment activities, provided that such positions and activities are not in
conflict, and do not otherwise interfere, with the Employee's duties and
responsibilities to the Company and its subsidiaries and other affiliates.

      4. COMPENSATION. As compensation for all services performed for the
Company and its subsidiaries and other affiliates during the term of this
Agreement, the Company shall pay the Employee a base salary at an annual rate
not less than Two Hundred Thousand Dollars ($ 200,000), subject to increase from
time to time by the Company in its discretion. Notwithstanding the foregoing,
the Company may reduce the Employee's base salary, but (i) only in the event of
a salary reduction affecting all or substantially all of the Company's officers
employed under an executive employment agreement and only in proportion to the
salary reductions applicable to such other affected officers and (ii) only if no
Change of Control has occurred.

      5. EMPLOYEE BENEFITS. During the term hereof, the Employee shall be
entitled to participate in any and all employee benefit plans from time to time
in effect for employees of the Company generally, excluding only plans providing
payments and/or other benefits in the event of termination of employment. Such
participation shall be subject to the terms of the applicable plan documents,
generally applicable Company policies and the discretion of the Board or any
administrative or other committee provided for in or contemplated by such plan.

      6. TERMINATION OF EMPLOYMENT. Notwithstanding the provisions of Section 2
above, the Employee's employment under this Agreement shall terminate under the
following circumstances and, in that event, the Company shall have only such
obligations to the Employee as are specified below under the applicable
termination provision:

            a. UPON DEATH. In the event of the Employee's death during the term
hereof, the Employee's employment hereunder shall immediately and automatically
terminate. In such event, the Company shall pay to the Employee's designated
beneficiary or, if no beneficiary has been designated by the Employee, to the
Employee's estate, any base salary earned and unpaid through the date of death.

            b. AS A RESULT OF DISABILITY. In the event that the Employee becomes
disabled during the term hereof and, as a result, is unable to perform
substantially all of his duties for the Company and, if applicable, its
subsidiaries and other affiliates, for more than one hundred and twenty (120)
days during any period of three hundred and sixty-five (365) days, the Company
may terminate the Employee's employment without further obligation upon notice
to the Employee. In the event of such disability, the Employee will continue to
receive his base salary and benefits under Sections 4 and 5 hereof until the
earlier of the date the Employee becomes eligible for disability income under
the Company's long-term disability or workers' compensation insurance plan or
the date his employment terminates.

            c. BY THE COMPANY FOR CAUSE. The Company may terminate the
Employee's employment for Cause at any time upon notice to the Employee setting
forth in reasonable detail the nature of such Cause. The following, as
determined by the Board in its reasonable judgment, shall constitute Cause for
termination: (i) the Employee's refusal to perform, or gross negligence in the
performance of, his duties or responsibilities on behalf of the Company and, if
applicable, its subsidiaries and other affiliates; (ii) the Employee's fraud,
embezzlement or other material dishonesty with respect to the Company or any of
its subsidiaries or other affiliates; (iii) the Employee's gross misconduct or
his conviction of, or plea of no contest to, a felony. In the event of such
termination, the Company shall have no further obligation to the Employee, other
than for base salary earned through the date of termination.

            d. BY THE COMPANY OTHER THAN FOR CAUSE. The Company may terminate
the Employee's employment other than for Cause upon notice to the Employee under
this subsection d or under subsection g below, whichever is applicable. In the
event of such termination prior to, or more than two years following, a Change
of Control and provided that the Employee executes the release of claims
attached hereto and marked "A" (the "Employee Release") within twenty-one (21)
days of his receipt of notice of termination of employment and does not timely
revoke the Employee Release, the Company:

                  i. shall pay the Employee severance pay in an amount equal to
            the sum of twelve (12) months' base salary at the rate in effect on
            the date of termination plus the amount of any performance bonus
            paid to the Employee in the calendar year immediately preceding that
            in which termination occurs, which the Employee may elect to receive
            (A) in a single lump sum, payable within thirty (30) days following
            the effective date of the Employee Release or (B) as salary
            continuation payable at the Company's regular payroll periods and in
            accordance with its regular payroll practices commencing on the next
            regular payday immediately following the effective date of the
            Employee Release, but retroactive to the date of termination and,

                  ii. at the Employee's election, (A) shall continue to pay, for
            the period of twelve (12) months following termination of the
            Employee's employment or, if earlier, until the date the Employee is
            covered under another employer's health plan that is comparable to
            that of the Company (the "Post-Employment Health Coverage Period"),
            that share of the premium cost of Employee's participation and that
            of his eligible dependents in the Company's group health plan as it
            pays for active employees of the Company and their eligible
            dependents generally OR (B) shall pay the Employee a single lump sum
            payment equal to the amount that the Company would have expended if
            participation had been elected and continued for a period of twelve
            (12) months, which lump sum shall be payable within thirty (30) days
            following the effective date of the Employee Release, and the
            Employee and his eligible dependents may exercise any rights they
            have 


                                       3
<PAGE>   4

            under Sections 601-607 of ERISA and Section 4980B of the
            Internal Revenue Code (collectively referred to as "COBRA") to
            continue participation in the group health plan at their cost,
            effective as of the date the Employee's employment terminates.
            Should the Employee elect option (A) above, the period of any
            continued health coverage to which the Employee and his eligible
            dependents may be entitled under COBRA as a result of the Employee's
            termination of employment will commence at the end of the
            above-defined Post-Employment Health Coverage Period.
            Notwithstanding anything to the contrary contained herein, the
            Employee may elect option (A) directly above only if the Employee
            elects to receive payment under subparagraph d.i., directly above,
            in the form of salary continuation.

            e. BY THE EMPLOYEE FOR GOOD REASON. The Employee may terminate
employment hereunder for Good Reason upon notice to the Company setting forth in
reasonable detail the nature of such Good Reason. The following shall constitute
Good Reason for termination by the Employee: (i) failure of the Company to
continue the Employee in an executive position in accordance with Section 3.a
above; (ii) a change adverse to the Employee in the Employee's primary reporting
relationship; (iii) material diminution in the nature or scope of the Employee's
responsibilities, duties or authority; (iv) material failure of the Company to
provide the Employee base salary and benefits in accordance with the terms of
Sections 4 and 5 hereof; or (v) a permanent transfer of the Employee to a work
site more than twenty-five miles distant from his work site on the Effective
Date. In the event of termination in accordance with this Section 6.e, the
Company shall provide the Employee severance pay and health insurance benefits
in accordance with Section 6.d hereof, provided that the Employee executes the
Employee Release within twenty-one (21) days of his notice of termination of
employment and provided further that the Employee does not timely revoke the
Employee Release.

            f. BY THE EMPLOYEE OTHER THAN FOR GOOD REASON. The Employee may
resign employment other than for Good Reason at any time upon one month's notice
to the Company. In the event of such termination, the Company shall have no
further obligation to the Employee, other than for base salary earned through
the date of termination.

            g. UPON A CHANGE OF CONTROL.

                  i. If a Change of Control (as defined in subsection g.ii
below) occurs and, within two (2) years following such Change of Control, the
Company terminates the Employee's employment other than for Cause, or the
Employee terminates his employment for Good Reason, and the Employee executes
the Employee Release within twenty-one (21) days of the date of notice of
termination of his employment and does not timely revoke it, then, in lieu of
any payment and benefits to which the Employee would otherwise be entitled under
Section 6.d or 6.e hereof, the Company


                                       4
<PAGE>   5

                        (1) shall pay the Employee an amount equal to the sum of
      twenty-four (24) months' base salary at the rate in effect on the date of
      termination of the Employee's employment plus two times the amount of any
      performance bonus paid to the Employee in the calendar year immediately
      preceding that in which termination occurs, which the Employee may elect
      to receive (A) in a single lump sum, payable within thirty (30) days
      following the effective date of the Employee Release or (B) as salary
      continuation payable at the Company's regular payroll periods and in
      accordance with its regular payroll practices commencing on the next
      regular payday following the effective date of the Employee Release, but
      retroactive to the date of termination, and

                        (2) at the Employee's election, (A) shall continue to
      pay, for the period of twenty-four months following termination of the
      Employee's employment or, if earlier, until the date the Employee is
      covered under another employer's health plan that is comparable to that of
      the Company (the "Change of Control Post-Employment Health Coverage
      Period"), that share of the premium cost of Employee's participation and
      that of his eligible dependents in the Company's group health plan as it
      pays for active employees of the Company and their eligible dependents
      generally OR (B) shall pay the Employee a single lump sum payment equal to
      the amount that the Company would have expended if participation had been
      elected and continued for a period of twenty-four (24) months, which lump
      sum shall be payable within thirty (30) days following the effective date
      of the Employee Release, and the Employee and his eligible dependents may
      exercise their rights under COBRA to continue participation in the group
      health plan at their cost effective as of the date his employment
      terminates. Should the Employee elect option (A) above, the period of any
      continued health coverage to which the Employee and his eligible
      dependents may be entitled under COBRA as a result of the Employee's
      termination of employment will commence at the end of the above-defined
      Change of Control Post-Employment Health Coverage Period. Notwithstanding
      anything to the contrary contained herein, the Employee may only elect
      option (A) directly above if the employee elects to receive payment under
      subparagraph g.i.(1) in the form of salary continuation.

                        (3) Upon a Change of Control as defined in the Company's
      Stock Compensation Plan as amended by the Company from time to time (the
      "Plan"), the vesting of any UST Restricted Common Stock ("Restricted
      Stock") or stock options to purchase UST Common Stock granted to the
      Employee and not yet exercised, expired, surrendered or canceled shall be
      in accordance with the Plan.

                        (4) If in connection with a Change of Control as defined
      in the Plan any other employees who hold stock options under the Plan or
      Restricted Stock will have their options or Restricted Stock or both
      cashed out, whether under the Plan or otherwise, the Employee shall have
      the right to have all or any of his options or Restricted Stock or both
      cashed out on the same basis and at the same time the options and
      Restricted Stock of such other employees are cashed out.

                  ii. Except as otherwise provided with respect to subparagraphs
g.i.(3) and g.i.(4) directly above, a "Change of Control" shall be deemed to
have been consummated if hereafter

                        (A) any "person", as such term used in Section 13(d) and
      14(d) of the Securities Exchange Act of 1934 as amended (the "Exchange
      Act") other than the Company or any of its subsidiaries or other
      affiliates or any trustee or other fiduciary holding securities under an
      employee benefit plan of the Company or any of its subsidiaries or other
      affiliates, becomes a beneficial owner (within the meaning of Rule 13d-3,
      as amended, as promulgated under the Exchange Act), directly or
      indirectly, of securities representing twenty-five (25%) percent or more
      of the combined voting power of the Company's then outstanding securities;
      or

                        (B) during any period of two consecutive years (not
      including any period prior to the Effective Date), individuals who at the
      beginning of such period constitute the Board, and any new director [other
      than a director designated by a person who has entered into an agreement
      with the Company to effect a transaction described in clause (A), (C) or
      (D) of this Section 6.g.(ii)] whose election by the Board or nomination
      for election by the Company's stockholders was approved by a vote of at
      least two-thirds of the directors then still in office who either were
      directors at the beginning of the period or whose election or nomination
      for election was previously so approved, cease for any reason to
      constitute at least a majority thereof; or

                        (C) there occurs a merger or consolidation of the
      Company with any other corporation, other than a merger or consolidation
      which would result in the voting securities of the Company outstanding
      immediately prior thereto continuing to represent (either by remaining
      outstanding or by being converted into voting securities of the surviving
      entity) more than eighty percent (80%) of the combined voting power of the
      voting securities of the Company or such surviving entity outstanding
      immediately after such merger or consolidation; provided, however, that a
      merger or consolidation effected to implement a recapitalization of the
      Company (or similar transaction) in which no "person" (as hereinabove
      defined) acquires more than twenty-five percent (25%) of the combined
      voting power of the Company's then outstanding securities shall not
      constitute a Change of Control; or

                        (D) the stockholders of the Company approve a plan of a
      complete liquidation of the Company; or

                        (E) there occurs a closing of a sale or other
      disposition by the Company of all or substantially all of the Company's
      assets.

            h. UPON EXPIRATION OF THE TERM HEREOF. Notice by the Company
pursuant to Section 2 hereof that this Agreement shall not renew shall be
treated as termination



                                       6
<PAGE>   7

by the Company other than for Cause pursuant to Section 6.d. Notice by the
Employee pursuant to Section 2 hereof that this Agreement shall not renew shall
be treated as a termination by the Employee of his employment other than for
Good Reason.

      7.    CONFIDENTIAL INFORMATION.

            a. The Employee acknowledges that the Company, its subsidiaries and
other affiliates continually develops Confidential Information, that the
Employee may develop Confidential Information for the Company, its subsidiaries
and other affiliates and that the Employee may learn of Confidential Information
during the course of employment. The Employee agrees to comply with the policies
and procedures of the Company for protecting Confidential Information and agrees
that he shall never disclose to any person, corporation or other entity, except
as required for the proper performance of his regular duties for the Company,
its subsidiaries and other affiliates, and shall never use for his own benefit
or that of another, any Confidential Information obtained by the Employee
incident to his employment or other association with the Company or any of its
subsidiaries or other affiliates. The Employee understands that this restriction
will continue to apply throughout his employment and after his employment
terminates, regardless of the reason for such termination; provided, however,
that the obligations contained in this Section 7 shall not apply to any
Confidential Information that becomes publicly known through no fault of the
Employee and shall not prevent the Employee from disclosing Confidential
Information as required by law or regulation.

            b. As used in this Agreement, "Confidential Information" means any
and all information of the Company, its subsidiaries and other affiliates, that
is not generally known by others with whom any of them competes or does
business, or with whom any of them plans to compete or do business, including
without limitation any and all information concerning the identity and special
needs of the customers of the Company, its subsidiaries and other affiliates and
the people and organizations with whom any of them has business relationships
and the substance of those relationships. Confidential Information also includes
any information received by the Company or any of its subsidiaries or other
affiliates from others with any understanding, express or implied, that it will
not be disclosed.

      8. NON-SOLICITATION. While the Employee is employed by the Company and (a)
for a period of two years following the termination of his employment pursuant
to Section 6.b or 6.c or 6.f hereof or (b) in the event of termination pursuant
to Section 6.d or 6.e or 6.g hereof, for a period equal to the months of
severance pay provided the Employee thereunder:

            (i) the Employee shall not, directly or indirectly, solicit or
encourage any customer of the Company or any of its subsidiaries or other
affiliates to terminate or diminish substantially its relationship with the
Company or any of its subsidiaries or other affiliates and

            (ii) the Employee shall not, directly or indirectly, hire or attempt
to hire any 


                                       7
<PAGE>   8

executive personnel of the Company or any of its subsidiaries or other
affiliates or solicit or encourage any executive personnel of the Company or any
of its subsidiaries or other affiliates to discontinue employment with the
Company or any of its subsidiaries or other affiliates.

For purposes of this Section 8, the term "months of severance pay" shall mean
the quotient of the total sum of payments to be made to the Employee under the
applicable termination provision divided by the Employee's base salary at the
monthly rate in effect on the date of termination.

      9. REMEDIES. The Employee acknowledges that, if he were to breach any of
the provisions of Section 7 or Section 8 of this Agreement, the harm to the
Company would be irreparable. The Employee therefore agrees that, in addition to
any other remedies available to it, the Company shall be entitled to obtain
preliminary and permanent injunctive relief against any such breach, without
having to post bond.

      10. TAXES. All payments made to the Employee under this Agreement shall be
reduced by any tax or other amount required to be withheld by the Company under
applicable law.

      11. REDUCTIONS. Notwithstanding anything to the contrary contained in this
Agreement, (a) any and all payments and benefits to be provided to the Employee
hereunder are subject to reduction to the extent required by applicable
statutes, regulations, rules and directives of federal, state and other
governmental and regulatory bodies having jurisdiction over the Company and/or
any of its subsidiaries or other affiliates and (b) the payments and benefits to
which the Employee would be entitled pursuant to Section 6.g hereof or otherwise
as a result of a Change of Control shall be reduced to the maximum amount for
which the Company will not be limited in its deduction pursuant to Section 280G
of the Internal Revenue Code of 1986, as amended, or any successor provision.
Any such reduction shall be applied to the amounts due to the Employee in such
manner as the Employee may reasonably specify within thirty (30) days following
notice from the Company of the need for such reduction or, if the Employee fails
to so specify timely, as determined by the Company.

      12. ASSIGNMENT. The Company may assign its rights and obligations under
this Agreement without the consent of the Employee in the event that the Company
shall hereafter effect a reorganization, consolidate with, or merge into, any
other person, corporation or other entity or transfer all or substantially all
of its assets to any other person, corporation or other entity. The Company
requires the personal services of the Employee and he may not assign this
Agreement. This Agreement shall inure to the benefit of and be binding upon the
Company and the Employee and their respective successors, executors,
administrators, heirs and permitted assigns.

      13. INDEMNIFICATION. The Company shall, and the Company shall use its best
efforts to cause its subsidiaries and other affiliates to, indemnify the
Employee to the maximum 


                                       8
<PAGE>   9

extent permitted by law and regulation in connection with any liability, expense
or damage which the Employee incurs or to which the Employee is exposed as a
result of the Employee's employment and positions with the Company and its
subsidiaries and other affiliates as contemplated by this Agreement, provided
that the Employee shall not be indemnified with respect to any matter as to
which he shall have been adjudicated in any proceeding not to have acted in good
faith in the reasonable belief that his action was in the best interest of the
Company and its subsidiaries and other affiliates. The Company, on behalf of
itself and its subsidiaries and other affiliates, hereby confirms that the
occupancy of all offices and positions which are occupied or held by the
Employee, now or hereafter, have been so occupied or held at the request of and
for the benefit of the Company and its subsidiaries and affiliates for purposes
of the Employee's entitlement to indemnification under applicable provisions of
the respective articles of organization and/or other similar documents of the
Company and its subsidiaries and other affiliates.

      14. MISCELLANEOUS. This Agreement sets forth the entire agreement between
the Company and the Employee and supersedes all prior communications, agreements
and understandings, whether written or oral, with respect to the Employee's
employment; provided, however, that this Agreement shall not terminate or
supersede any agreement between the parties with respect to the securities of
the Company. The headings and captions contained herein are for convenience of
reference only and are not part of this Agreement. This Agreement may not be
modified or amended, and no breach of this Agreement shall be deemed to be
waived, unless agreed to in writing by the Employee and the Company. This is a
Massachusetts contract and shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts.

      15. NOTICES. Any notices provided for in this Agreement shall be in
writing and shall be effective when delivered in person or deposited in the
United States mail, postage prepaid, and addressed to the Employee at his last
known address on the books of the Company or, in the case of the Company, at its
main office, attention of the Senior Vice President, Human Resources with a copy
to the General Counsel of the Company.

      IN WITNESS WHEREOF, this Agreement has been executed as a sealed
instrument by the Company, by its duly authorized representative, and by the
Employee, as of the date first written above.

                                RELEASE OF CLAIMS

      FOR AND IN CONSIDERATION OF the special payments to be made to me in
connection with my separation of employment, as set forth in the employment
agreement between UST Corp and me dated as of the 10th day of August, 1998 (the

beneficiaries and representatives and all others connected with me, hereby
release and forever discharge UST Corp. (the "Company"), its subsidiaries and
other affiliates, and all of their respective officers, directors, shareholders,
employees, agents, representatives, successors and assigns and all others
connected with them (all collectively, the "Released"), both individually and in
their official capacities, from any and all liabilities, claims, demands,
actions and causes of action of any type (all collectively "Claims") which I
have had in the past, now have, or might now have, through the date of my
execution of this Release of Claims, in any way resulting from, arising out of
or connected with my employment or its termination or pursuant to any federal,
state or local employment law, regulation or other requirement (including
without limitation Title VII of the Civil Rights Act of 1964, the Age
Discrimination in Employment Act, the Americans with Disabilities Act, and the
Massachusetts fair employment practices act, each as may be amended).

      Excluded from the scope of this Release of Claims is (i) any claim arising
hereafter under the terms of the Employment Agreement or under the terms of any
of the Company's qualified and non-qualified employee benefit plans (including
without limitation the Company's employee pension plan, profit sharing plan or
stock ownership plan) and (ii) any right of indemnification or contribution
pursuant to the Articles of Organization or By-Laws of the Company that I have
or hereafter acquire if any claim is asserted or proceedings are brought against
me by any governmental or regulatory agency, or by any customer, creditor,
employee or shareholder of the Company, or by any self-regulatory organization,

officer or employee of the Company or to any of my activities as an officer or
employee of the Company.

      By acceptance of or reliance on this Release of Claims, the Company
promises that neither it nor any of the other Released affiliated with the
Company will taken any action that is designed, specifically as to me or with
respect to a class of similarly situated former employees, to reduce or
abrogate, or may reasonably be expected to result in an abridgement or
elimination of, any rights of indemnification or contribution available to me
pursuant to the Articles of Organization or By-Laws of the Company, or under any
policy or policies of directors and officers liability insurance affording
coverage to former officers and in effect from time to time, unless any such
abridgement or elimination of rights is also generally applicable to
then-current officers and employees of the Company.

      In signing this Release of Claims, I acknowledge that I have had at least
twenty-one

            under the Plan only if all of the following three conditions are
            met: (i) the employee is on the Company's active payroll or on a
            leave of absence that has been approved in writing, with guaranteed

            termination occurs in one of the following circumstances:

            1.    The participating employee's employment is terminated as a
                  result of the elimination of his/her position with the Company
                  in conjunction with a reduction in force or a corporate
                  restructuring and the employee is not offered employment in a
                  comparable position with the Company or one of its Affiliates;
                  or

            2.    The employee's employment is terminated other than for Cause
                  by the Company within twelve (12) months following a Change in
                  Control; and

            3.    The employee is not then covered by another severance pay plan
                  or by an individual employment agreement or other severance
                  arrangement providing benefits that in the aggregate are
                  comparable to or exceed those for which the employee would
                  otherwise be eligible under this Plan; and (iii) the
                  participating employee executes the release of claims attached
                  hereto and marked "A" (the "Employee Release") within
                  forty-five (45)

                  days of the date on which he/she receives notice of
                  termination of his/her employment, and does not timely revoke
                  it.

IV.   EXCLUSIONS

                  employment with the Company; or

            2.    The employee's employment is terminated by the Company for
                  Cause; or

            3.    The employee is offered comparable employment at
                  the time of the elimination of his/her position; or

            4.    The employee is temporarily laid off; or

            5.    The employee is on a leave of absence which has not been
                  approved in writing or as to which reinstatement is not
                  guaranteed; or

            6.    The employee elects not to execute the Employee Release.

      B.    This Plan does not constitute a contract of employment for a
            specific term or otherwise alter the at-will nature of the
            employment relationship between any employee and the Company.

V.    BENEFITS

      A.    Benefits under this Plan are determined by length of service, as
            follows:

            1.    Six (6) months' pay, at the participating employee's final
                  base rate of pay, if the participating employee has not more
                  than three (3) full years of service with the Company as of
                  the date employment terminates; or

            2.    Nine (9) months' pay, at the participating employee's final
                  base rate of pay, if the participating employee has more than
                  three (3) full years of service, but not more than six (6)
                  full years of service, with the Company as of the date his/her
                  employment terminates.

            3.    Twelve (12) months' pay, at the participating employee's final
                  base rate of pay, if the participating employee has more than
                  six (6) full years of service with the Company as of the date
                  his/her employment terminates.

      B.    Provided that the participating employee elects to receive benefits
            as salary continuation under option 2 of paragraph D of this Section
            V, and provided further that the participating employee is currently
            enrolled in, and exercises his/her right to continue coverage, under
            the Company's group heath plan in accordance with applicable federal
            law ("COBRA"), then, for the duration of the period in which the
            participating employee is receiving such salary continuation or, if
            earlier, until the date the participating employee ceases to be
            eligible for continued coverage in accordance with COBRA, the
            Company shall continue to pay that share of the premium cost of the
            participating employee's coverage and that of his/her eligible
            dependents under the Company's group health plan that it pays for
            active employees of the Company and their eligible dependents
            generally or, following a Change of Control, the amount the Company
            was paying for active employees of

                                      -2-
<PAGE>   3
            the Company and their eligible dependents generally immediately
            prior to such Change of Control if greater.

            employee hereunder, service with the Company which occurred prior to
            a break in service of two (2) years or more shall not be included.

      D.    Benefits under Section V.A for which a participating employee is
            eligible shall be reduced by all taxes and other amounts which the
            Company is required to withhold under applicable law and shall be
            payable, at the participating employee's election, (1) in a single
            lump sum within thirty (30) days following the effective date of the
            Employee Release or (2) as salary continuation payable at the
            Company's regular payroll periods and in accordance with its regular
            payroll practices commencing on the next payday immediately
            following the effective date of the Employee Release, but
            retroactive to the date of termination of the participating
            employee's employment.

      E.    Benefits otherwise payable under this Plan shall be reduced by any
            amounts to which the employee is entitled under applicable law as a
            result of the termination of his/her employment.

      F.    The Company pays the full cost of benefits provided under this Plan
            from the Company's general assets.

      G.    Benefits under this Plan are not assignable or subject to
            alienation. Likewise, benefits are not subject to attachments by
            creditors or through legal process against the Company or any
            employee.

      H.    Notwithstanding anything to the contrary contained herein, any and
            all payments to be provided hereunder to or on behalf of any
            participating employee are subject to reduction to the extent
            required by applicable statutes, regulations, rules and directives
            of federal, state and other governmental and regulatory bodies
            having jurisdiction over the Company and/or any of its Affiliates.

VII.  ADMINISTRATION, CLAIMS PROCEDURE AND GENERAL INFORMATION

      A.    The Company reserves the right to amend, modify and terminate the
            Plan. Also, the Company, as the Plan administrator within the
            meaning of ERISA, reserves full discretion to administer the Plan in
            all of its details, subject to the requirements of law. The Company
            shall have such discretionary powers as are necessary to discharge
            its duties. Any interpretation or determination that the Company
            makes regarding this Plan, including without limitation
            determinations of eligibility, participation and benefits, will be
            final and conclusive, in the absence of clear and convincing
            evidence that the Company acted arbitrarily and capriciously.

      B.    Notwithstanding anything to the contrary contained herein, this Plan
            may not be modified, amended or terminated during the first twelve
            (12) months following a Change of Control and any participating
            employee who is designated as an "Senior Officer" for purposes of
            this Plan at the time of a Change of Control will remain so
            designated for twelve (12) months following that Change of Control.

      C.    If you believe you are being denied any rights under the Plans, you
            may file a claim in writing with the Company, as Plan administrator.
            If your claim is denied, in whole or in part, the Plan administrator
            will notify you in writing, giving the specific reasons for the
            decision, including specific reference to the pertinent Plan
            provisions and a description of any additional material or
            information necessary to perfect your claim and an explanation of
            why such material or information is necessary. The written notice
            will also advise you of your right to request a review of your claim
            and the steps that need to be taken if you wish to submit your claim
            for review. If the Plan administrator does not notify you of its
            decision within 90 days after it had received your claim (or within
            180 days, if special circumstances exist requiring additional time,
            and if you had been given a written explanation for the extension
            within the initial 90-day period), you should consider your claim to
            have been denied. At this time you may request a review of the
            denial of your claim.

            A request for review must be made in writing by you or your duly
            authorized representative to the Company, as Plan administrator,
            within 60 days after you have received the notice of denial. As part
            of your request, you may submit written issues and comments to the
            Plan administrator, review pertinent documents, and request a
            hearing. The Plan administrator's written decision will be made
            within 60 days (or 120 days if a hearing is held or if other special
            circumstances exist requiring more than 60 days and written notice
            of the extension is provided to you within the initial 60-day
            period) after your request has been received. Again, the decision
            will include specific reasons, including references to pertinent
            Plan provisions.

have, or might now have, through the date of my execution of this Release of
Claims, in any way resulting from, arising out of or connected with my
employment or its termination or pursuant to any federal, state or local
employment law, regulation or other requirement (including without limitation
Title VII of the Civil Rights Act of 1964, as amended, the Age Discrimination in
Employment Act, as amended, the Americans with Disabilities Act, as amended, and

related or allegedly related to my having been an officer or employee of the
Company or to any of my activities as an officer or employee of the Company.

      By acceptance of or reliance on this Release of Claims, the Company
promises that neither it nor any of the other Releasees affiliated with the
Company will taken any action that is designed, specifically as to me or with
respect to a class of similarly situated former employees, to reduce or
abrogate, or may reasonably be expected to result in an abridgment or
elimination of, any rights of indemnification or contribution available to me
pursuant to the Articles of Organization or By-Laws of the Company, or under any
policy or policies of directors and officers liability insurance affording
coverage to former officers and in effect from time to time, unless any such
abridgment or elimination of rights is also generally applicable to then-current
officers and employees of the Company.

      In signing this Release of Claims, I acknowledge that I have had at least
forty-five (45) days from the date of my receipt of notice of termination of my
employment to consider the terms of this Release of Claims, that I am encouraged
by the Company to seek the advice of an attorney prior to signing this Release
of Claims and that I am signing this Release of Claims voluntarily and with a
full understanding of its terms. I understand that I may revoke this Release of
Claims at any time within
<PAGE>   7
seven (7) days of the date of my signing by written notice to the President of
the Company and that this Release of Claims will take effect only upon the
expiration of such seven-day revocation period and only if I have not timely
revoked it.

      IN WITNESS WHEREOF, I have set my hand and seal on the date written below.

<PAGE>   10
3.       APPORTIONMENTS.

         The following shall be apportioned between the Seller and the Purchaser
at the Closing as of 11:59 p.m. of the day preceding the Closing Date (the
"Adjustment Date"):

         (a)   to the extent applicable, collected, fixed or base rents
("Rents") which have been prepaid, security deposits referred to in Section
8(d), collected Rents for the month in which the Closing occurs and Additional
Rents and other amounts paid by tenants applicable to periods which expire after
the Closing Date, which have been received by Seller;

         (b)   to the extent applicable, real estate taxes, special
assessments (but only any installment relating to the period in which the
Adjustment Date occurs), water charges, sewer rents and charges and vault
charges, if any, on the basis of the fiscal years (or applicable billing period
if other than a fiscal year), respectively, for which same have been assessed;

         (c)   utilities, to the extent required by Section 3.4;

         (d)   such other items as are customarily apportioned between
sellers and purchasers of real properties of a type similar to the Property and
located in Boston, Massachusetts.

         3.1   TAXES.

         If the amount of real estate taxes, special assessments or other taxes
for the Property for the fiscal year during which Closing occurs is not finally
determined at the Adjustment Date, such taxes shall be apportioned on the basis
of the full amount of the assessment for such period (or the assessment for the
prior tax period if the assessment for the current tax period is not then known)
and the rate for the immediately prior tax year, and shall be reapportioned as
soon as the new tax rate and valuation, if any, has been finally determined. If
any taxes which have been apportioned shall subsequently be reduced by
abatement, the amount of such abatement, less the cost of obtaining the same and
after deduction of sums payable to the tenant under the Lease or expired or
terminated leases of the Property, shall be equitably apportioned between the
parties hereto.

         3.2   RENTS.

                  3.2.1    ARREARAGES.

                  If on the Closing Date the tenant under the Lease is in
arrears in the payment of Rent or has not paid the Rent payable by it for the
month in which the Closing occurs (whether or not it is in arrears for such
month on the Closing Date), any Rents received by the Purchaser or the Seller
from such tenant after the Closing shall be applied to amounts due and payable
by such tenant during the following periods in the following order of priority:
(i) first, to the month in which the payment is received, (ii) second, if
applicable, to the months following the month in which the Closing occurred and
(iii) third, to the month preceding the month in which the Closing occurred. If
Rents or any portion thereof received by the Seller or the Purchaser after the
Closing are due and payable to the other party by 
<PAGE>   11
reason of this allocation, the appropriate sum, less a proportionate share of
any reasonable attorneys' fees and costs and expenses expended in connection
with the collection thereof, shall be promptly paid to the other party (to the
extent not collected from or reimbursed by the tenant under the Lease).

                  3.2.2    ADDITIONAL RENTS.

                  If the tenant under the Lease is required to pay percentage
rent, escalation charges for real estate taxes, parking charges, operating
expenses and maintenance escalation charges, cost-of-living increases or other
charges of a similar nature ("Additional Rents") and any Additional Rents are
collected by the Purchaser from such tenant after the Closing Date, then the
Purchaser shall promptly pay to the Seller out of the first such sums received
from such tenant the amount of all Additional Rents which are due and payable by
such tenant with respect to any period prior to the Closing Date (whether or not
such Additional Rents first became due and payable on or after the Closing
Date), less a proportionate share of any reasonable attorneys' fees and costs
and expenses of collection thereof (to the extent not collected from or
reimbursed by the tenant under the Lease).

                  3.2.3    COLLECTION AFTER THE CLOSING.

                  After the Closing, the Seller shall continue to have the
right, in its own name, to demand payment of and to collect Rent and Additional
Rent arrearages owed to the Seller by the tenant under the Lease, which right
shall include, without limitation, the right to continue or commence legal
actions or proceedings against such tenant. The Purchaser agrees to reasonably
cooperate with the Seller in connection with all efforts by the Seller to
collect such Rents and Additional Rents and to take all steps, whether before or
after the Closing Date, as may be reasonably necessary to carry out the
intention of the foregoing, including, without limitation, the delivery to the
Seller, upon demand, of any relevant books and records (including any Rent or
Additional Rent statements, receipted bills and copies of tenant checks used in
payment of such Rent or Additional Rent), the execution of any and all consents
or other documents, and the undertaking of any act reasonably necessary for the
collection of such Rents and Additional Rents by the Seller.

         3.3   WATER.

         If there is a water meter on the Property, the Seller shall furnish a
reading to a date not more than thirty (30) days prior to the Closing Date, and
the unfixed water charges and sewer rent, if any, based thereon for the
intervening time shall be apportioned on the basis of such last reading.

         3.4   UTILITIES.

         The Seller will attempt to obtain final cut-off readings of fuel,
telephone, electricity, and gas to be made as of the Adjustment Date. The Seller
shall pay or cause the tenant under the Lease to pay the bills based on such
readings promptly after the same are rendered. If arrangements cannot be made
for any such cut-off reading, the parties shall apportion the 
<PAGE>   12
charges for such services on the basis of the bill therefor for the most recent
billing period prior to the Adjustment Date, and when final bills are rendered
for the period which includes the Adjustment Date the Seller and Purchaser shall
promptly readjust the apportionments in accordance with such final bills.

         3.5   POST-CLOSING ADJUSTMENTS.

         The items set forth in this Section 3 shall be apportioned at the
Closing by payment of the net amount of such apportionments to the Seller in the
manner set forth herein for the payment of the Purchase Price if the net
apportionment is in favor of the Seller or by a credit against the Purchase
Price if the net apportionment is in favor of the Purchaser. However, if any of
the items subject to apportionment under the foregoing provisions of this
Section 3 cannot be apportioned at the Closing because of the unavailability of
the information necessary to compute such apportionment, or if any errors or
omissions in computing apportionments at the Closing are discovered subsequent
to the Closing, then such item shall be reapportioned and such errors and
omissions corrected as soon as practicable after the Closing Date and the proper
party reimbursed, which obligation shall survive the Closing for a period of one
year after the Closing Date. Notwithstanding any of the foregoing provisions of
this Section 3.5 to the contrary, the Purchaser and the Seller agree that the
one year limitation set forth in this Section 3.5 shall not apply to the
parties' obligations under Sections 3.1 and 3.2 and that such obligations shall
survive the Closing forever.

4.       DUE DILIGENCE PERIOD.

         Notwithstanding anything to the contrary contained herein, the
Purchaser had a period which commenced prior to the date hereof and terminated
at 5:00 p.m. (EST) on November 6, 1998 (the "Due Diligence Period") to examine
title to the Property, to inspect the physical condition of the Property and to
review the Property Information. Neither the Purchaser nor the Purchaser's
Representatives were permitted during the Due Diligence Period to contact any
governmental authority or any of the Seller's tenants, vendors, employees,
consultants or contractors prior to the Closing without (i) providing Seller
with one (1) day prior written notice of such contact, and (ii) if Seller so
requested within such one (1) day period, a representative of Seller being
present. Nothing contained in this Section 4 is intended to preclude Purchaser
from reviewing public records such as documents on record at the Middlesex
County (Southern District) Registry of Deeds or the building jacket for the
Building on file with the Medford Building Inspector.

         4.1   ACCESS TO THE PROPERTY.

         During the Due Diligence Period, the Purchaser and the Purchaser's
Representatives had the right to enter upon the Property for the sole purpose of
inspecting the Property and making surveys, and other investigations,
inspections and tests of the Property, including, without limitation, all
structural and mechanical systems within the Building (collectively,
"Investigations" which term shall not include Purchaser's internal work
product), provided (i) the Purchaser gave the Seller not less than one (1)
business days' prior written notice before each entry, and (ii) the first such
notice shall include sufficient information to permit the Seller 
<PAGE>   13
to review the scope of the proposed Investigations. Purchaser did not during the
Due Diligence Period and does not now have the right to conduct any subsurface
investigations at the Property, any such investigations shall be undertaken by
the Seller pursuant to Section 13.3(a) hereof. Any entry upon the Property and
all Investigations during the Due Diligence Period were to have been during the
Seller's normal business hours and were and remain at the sole risk and expense
of the Purchaser and the Purchaser's Representatives, and were not to have
disrupted the activities on or about the Property of the Seller, its tenants and
their employees and invitees in any substantial manner. The Purchaser was
required during the Due Diligence Period and remains obligated to:

                  (a) promptly repair any damage to the Property resulting from
         any such Investigations and replace, refill and regrade any holes made
         in, or excavations of, any portion of the Property used for such
         Investigations so that the Property shall be in the same condition as
         that which existed prior to such Investigations;

                  (b) fully comply with all Laws applicable to the
         Investigations and all other activities undertaken in connection
         therewith;

                  (c) permit the Seller and/or the tenant under the Lease to
         have a representative present during all Investigations undertaken
         hereunder;

                  (d) take all actions and implement all protections necessary
         to ensure that all actions taken in connection with the Investigations,
         and the equipment, materials, and substances generated, used or brought
         onto the Property pose no threat to the safety or health of persons or
         the environment, and cause no damage to the Property or other property
         of the Seller or other persons;

                  (e) if requested by the Seller, furnish to the Seller, at no
         cost or expense to the Seller, copies of all surveys, engineering,
         asbestos, environmental and other studies and reports relating to the
         Investigations which the Purchaser shall obtain from third party
         consultants with respect to the Property promptly after the Purchaser's
         receipt of same, Seller hereby waives any claims, actions or causes of
         action against Purchaser or any such third party consultant with
         respect to the accuracy or completeness of any such studies or reports
         delivered to Seller by Purchaser;

                  (f) maintain or cause to be maintained, at the Purchaser's
         expense, a policy of comprehensive general public liability insurance
         with a combined single limit of not less than $1,000,000 per occurrence
         for bodily injury and property damage, automobile liability coverage
         including owned and hired vehicles with a combined single limit of
         $1,000,000 per occurrence for bodily injury and property damage, and an
         excess umbrella liability policy for bodily injury and property damage
         in the minimum amount of $3,000,000, insuring the Purchaser and the
         Seller and certain of Seller's Affiliates listed on Schedule 2, as
         additional insureds, against any injuries or damages to persons or
         property that may result from or are related to (i) the Purchaser's
         and/or the Purchaser's Representatives' entry upon the Property, (ii)
         any Investigations or other activities conducted thereon, and (iii) any
         and all other activities undertaken by the 
<PAGE>   14
         Purchaser and/or the Purchaser's Representatives in connection with the
         Property, and deliver evidence of such insurance policy to the Seller
         at the earlier of ten (10) days after the date of this Agreement or the
         first entry on the Property; and

                  (g) subject to the final sentence of Section 17 hereof,
         indemnify the Seller and the Seller's Affiliates and hold the Seller
         and the Seller's Affiliates harmless from and against any and all
         claims, demands, causes of action, losses, damages, liabilities, costs
         and expenses (including without limitation attorneys' fees and
         disbursements), suffered or incurred by the Seller or any of the
         Seller's Affiliates and arising out of or in connection with (i) the
         Purchaser and/or the Purchaser's Representatives' entry upon the
         Property, (ii) any Investigations or other activities conducted thereon
         by the Purchaser or the Purchaser's Representatives, and (iii) any
         liens or encumbrances filed or recorded against the Property as a
         consequence of the Investigations or any other activities conducted
         thereon by the Purchaser or the Purchaser's Representatives.

         The provisions of this Section 4.1 shall survive the termination of
this Agreement and the Closing.

         4.2   PURCHASER'S TERMINATION NOTICE.

         Subject to the provisions of the last paragraph of this Section 4.2,
the Purchaser shall have the right to elect to terminate this Agreement by
giving written notice (the "Purchaser's Termination Notice") of such election to
the Seller at any time prior to the expiration of the Due Diligence Period if
the Purchaser shall determine, in Purchaser's sole discretion, that the Property
is not satisfactory for any reason whatsoever.

         If for any reason whatsoever the Seller shall not have received the
Purchaser's Termination Notice prior to the expiration of the Due Diligence
Period, the Purchaser shall be deemed to have irrevocably waived the right of
termination granted under this Section 4.2, and such right of termination shall
be of no further force or effect, provided, however, failure by the Purchaser to
deliver Downpayment B on or before the date hereof shall be deemed receipt by
Seller of Purchaser's Termination Notice as of such time and date.

         Purchaser and Seller acknowledge and agree that the Due Diligence
Period has terminated and that the Purchaser has no right to terminate the
Agreement pursuant to this Section 4.2.

         4.3   ESTOPPEL CERTIFICATE.

         The Seller shall use reasonable efforts to obtain an estoppel
certificate from the tenant under the Lease (i) as soon as practicable after
November 6, 1998; and (ii) in the event that the tenant under the Lease is still
in occupancy of the Property on the Closing Date, within thirty (30) days of the
Closing Date, but in no event shall it be deemed to be an obligation of the
Seller under this Agreement to obtain either executed estoppel certificate. The
estoppel certificates shall be in the form annexed hereto as Exhibit F and made
a part hereof. If the tenant under the Lease fails to deliver either estoppel
certificate in the form required by this 
<PAGE>   15
Agreement, Seller shall have the right to substitute in lieu thereof an estoppel
certificate substantially in such form executed by Seller and such estoppel
certificate shall be treated for all purposes as an estoppel certificate from
such tenant. In the event that the tenant under the Lease is no longer in
occupancy of the Property as of the Closing Date, the Seller shall provide the
Purchaser with a certificate at Closing indicating that the tenant under the
Lease has vacated the Property. Purchaser shall not contact the tenant under the
Lease prior to Closing without (i) providing Seller with one (1) day prior
written or telephonic notice of such contact, and (ii) if Seller so requests,
within such one (1) day period, a representative of Seller being present.

5.       TITLE.

         The Seller shall convey and the Purchaser shall accept title to the
Property subject to those matters set forth on Schedule 3 hereto (collectively
the "Permitted Encumbrances"). The Seller has delivered to the Purchaser, at the
Seller's expense, a commitment for an owner's fee title insurance policy with
respect to the Property (the "Title Commitment") from Chicago Title Insurance
Company (the "Title Company"), together with true and complete copies of all
instruments giving rise to any defects or exceptions to title to the Property.
The Seller has delivered to the Purchaser, at the Seller's expense, an as-built
survey ("Survey") of the Land and Building after the date of this Agreement and
prepared in accordance with the "Minimum Standard Detail Requirements for
ALTA/ACSM Land Title Surveys" for Urban Surveys (including Table A items 1, 2,
3, 4, 6, 7, 8, 9, 10, 11 and 13) jointly established and adopted by ALTA and
ACSM in 1992.

         5.1   UNACCEPTABLE ENCUMBRANCES.

         If the Title Commitment or the Survey indicate the existence of any
liens or encumbrances (collectively, "Liens") or other defects or exceptions in
or to title to the Property other than the Permitted Encumbrances (collectively,
the "Unacceptable Encumbrances") subject to which the Purchaser is unwilling to
accept title and the Purchaser gives the Seller notice of the same within
fourteen (14) days after the later to occur of Purchaser's receipt of (i) the
Title Commitment or (ii) the Survey, and the Seller shall undertake to eliminate
the same (or to arrange for title insurance insuring against enforcement of such
Unacceptable Encumbrances against, or collection of the same out of, the
Property) subject to Section 5.2. The Purchaser hereby waives any right the
Purchaser may have to advance as objections to title or as grounds for the
Purchaser's refusal to close this transaction any Unacceptable Encumbrance which
the Purchaser does not notify the Seller of within such fourteen (14) day period
unless (i) such Unacceptable Encumbrance was first raised by the Title Company
subsequent to the date of the Title Commitment or the Purchaser shall otherwise
first discover same or be advised of same subsequent to the date of the Title
Commitment or the Survey, respectively, and (ii) the Purchaser shall notify the
Seller of the same within five (5) days after the Purchaser first becomes aware
of such Unacceptable Encumbrance. Seller agrees to notify Purchaser within five
(5) days of any new liens of record of which Seller has actual knowledge of and
which arise subsequent to the date of the Title Commitment. The Seller, in its
sole discretion, may adjourn the Closing one or more 
<PAGE>   16
times for up to sixty (60) days in the aggregate in order to eliminate
Unacceptable Encumbrances provided, however, that the Closing may not be
adjourned beyond June 30, 1999.

         5.2   REMOVAL OF UNACCEPTABLE ENCUMBRANCES.

         The Seller shall not be obligated to bring any action or proceeding, to
make any payments or otherwise to incur any expense in order to eliminate
Unacceptable Encumbrances not waived by the Purchaser or to arrange for title
insurance insuring against enforcement of such Unacceptable Encumbrances
against, or collection of the same out of, the Property; except that the Seller
shall satisfy Unacceptable Encumbrances which are (i) mortgages and past due
real estate taxes and assessments secured by or affecting the Property, and (ii)
judgments against the Seller or other Liens secured by or affecting the Property
which judgments and other Liens can be satisfied by payment of liquidated
amounts not to exceed $2,000,000 in the aggregate for all such judgments and
other Liens. The Seller may eliminate any such Unacceptable Encumbrance by the
payment of amounts necessary to cause the removal thereof of record, by bonding
over such Unacceptable Encumbrance in a manner reasonably satisfactory to the
Purchaser or by arranging for title insurance reasonably satisfactory to the
Purchaser insuring against enforcement of such Unacceptable Encumbrance against,
or collection of the same out of, the Property.

         5.3   OPTIONS UPON FAILURE TO REMOVE UNACCEPTABLE LIENS.

         If the Seller is unable or is not otherwise obligated (pursuant to
Section 5.2) to eliminate all Unacceptable Encumbrances not waived by the
Purchaser, or to bond over in a manner reasonably satisfactory to the Purchaser
any Unacceptable Encumbrances not waived by the Purchaser, or to arrange for
title insurance reasonably acceptable to the Purchaser insuring against
enforcement of such Unacceptable Encumbrances against, or collection of the same
out of, the Property, and to convey title in accordance with the terms of this
Agreement on or before the Closing Date (whether or not the Closing is adjourned
as provided in Section 5.1), the Purchaser shall elect on the Closing Date, as
its sole remedy for such inability of the Seller, either (i) to terminate this
Agreement by notice given to the Seller pursuant to Section 14.1, in which event
the provisions of Section 14.1 shall apply, or (ii) to accept title subject to
such Unacceptable Encumbrances and receive no credit against, or reduction of,
the Purchase Price.

         5.4   USE OF PURCHASE PRICE.

         If on the Closing Date there may be any Liens or other encumbrances
which the Seller must pay or discharge in order to convey to the Purchaser such
title as is herein provided to be conveyed, the Seller may use any portion of
the Purchase Price to satisfy the same, provided:

                  (a) the Seller shall deliver to the Purchaser or the Title
         Company, at the Closing, instruments in recordable form and sufficient
         to satisfy such Liens or other encumbrances of record together with the
         cost of recording or filing said instruments; or
<PAGE>   17
                  (b) the Seller, having made arrangements with the Title
         Company, shall deposit with said company sufficient moneys acceptable
         to said company to insure the obtaining and the recording of such
         satisfactions.

         5.5   TRANSFER TAXES; TITLE INSURANCE PREMIUMS.

         At the Closing, the Seller shall pay all transfer taxes (the "Transfer
Tax Payments") imposed pursuant to the Laws of the Commonwealth of Massachusetts
or any other governmental authority in respect of the transactions contemplated
by this Agreement by delivery to the Title Company of sufficient funds to pay
such taxes. At the Closing, the premiums due the Title Company to obtain title
insurance policies in the form contemplated by the Title Commitment (as the same
may be amended pursuant to this Agreement), the cost of obtaining the Survey,
and recording fees of the Title Company shall be paid by the Purchaser. Any fee
owed to the Escrow Agent for its services as Escrow Agent shall be divided
equally between Purchaser and Seller. The Seller shall also pay for the cost of
recording any lien discharges which are required in order for Seller to deliver
title to the Property in accordance with the terms of this Agreement.

6.       REPRESENTATIONS AND WARRANTIES OF THE SELLER.

         The Seller represents and warrants to the Purchaser as follows:

                  (a) The Seller is a duly formed and validly existing limited
         partnership organized under the laws of the Commonwealth of
         Massachusetts and is qualified under the laws of the Commonwealth of
         Massachusetts to conduct business therein.

                  (b) The Seller has the full, legal right, power and authority
         to execute and deliver this Agreement and all documents now or
         hereafter to be executed by the Seller pursuant to this Agreement
         (collectively, the "Seller's Documents"), to consummate the transaction
         contemplated hereby, and to perform its obligations hereunder and under
         the Seller's Documents.

                  (c) This Agreement and the Seller's Documents do not and will
         not contravene any provision of the limited partnership agreement of
         the Seller, any judgment, order, decree, writ or injunction issued
         against the Seller, or, to the Seller's actual knowledge, any provision
         of any laws or governmental ordinances, rules, regulations, orders or
         requirements (collectively, the "Laws") applicable to the Seller. The
         consummation of the transactions contemplated hereby will not result in
         a breach or constitute a default or event of default by the Seller
         under any agreement to which the Seller or any of its assets are
         subject or bound and will not result in a violation of any Laws
         applicable to the Seller.

                  (d) The Seller has no actual knowledge of any leases,
         licenses, other occupancy agreements or material agreements which will
         survive termination of the Lease and the conveyance of the Property to
         Purchaser affecting any portion of the Property on the date hereof,
         except for (i) the Lease described in Schedule 4 annexed 
<PAGE>   18
         hereto and made a part hereof (the "Lease"); and (ii) any other
         instrument described on Schedule 4. To Seller's actual knowledge, the
         copy of the Lease furnished by the Seller to the Purchaser is true and
         complete. To the Seller's actual knowledge, the Lease is in full force
         and effect, without any material default by the Seller or the tenant
         thereunder. To the Seller's actual knowledge, except as listed on
         Schedule 4, the Seller has not given or received any notice of default
         which remains uncured or unsatisfied, with respect to the Lease, nor
         does any condition exist which with the passage of time the giving of
         notice or would constitute a default under the Lease by Seller or the
         tenant under the Lease.

                  (e) To the Seller's actual knowledge, there are no pending
         actions, suits, proceedings or investigations to which the Seller is a
         party before any court or other governmental authority with respect to
         the Property owned by the Seller except as set forth on Schedule 5
         hereto. To the best of Seller's actual knowledge, Seller has not
         received written notice of a threat of any such actions, suits,
         proceedings or investigations except as set forth on Schedule 5.

                  (f) To the best of Seller's actual knowledge, Seller has not
         received notice from any insurance company of any defects or
         inadequacies in any portion of the Property.

                  (g) From and after the date hereof until the termination of
         this Agreement by virtue of sale of the Property to the Purchaser or
         otherwise, the Seller shall not enter into any agreement for the sale
         of the Property, including, without limitation, any agreement for the
         sale of the Property which is contingent upon the termination of this
         Agreement.

                  (h) Except as set forth in the Lease and in this Agreement,
         Seller has not granted any options to acquire the Property or leases to
         occupy all or any portion of the Property, which remain in effect.

         6.1   SURVIVAL OF REPRESENTATIONS.

         The representations and warranties of the Seller set forth in this
Section 6 (i) shall be true, accurate and correct in all material respects upon
the execution of this Agreement and shall be deemed to be repeated on and as of
the Closing Date (except as they relate only to an earlier date), and (ii) shall
remain operative and shall survive the Closing and the execution and delivery of
the Deed for a period of one year following the Closing Date and then shall
expire, and no action or claim based thereon shall be commenced after such
period.

         6.2   DISCOVERY OF UNTRUE REPRESENTATION.

         If at or prior to the Closing, (i) the Purchaser shall become aware
that any of the representations or warranties made herein by the Seller is
untrue, inaccurate or incorrect in any material respect and shall give the
Seller notice thereof at or prior to the Closing, or (ii) the Seller shall
notify the Purchaser that a representation or warranty made herein by the Seller
is 
<PAGE>   19
untrue, inaccurate or incorrect, then the Seller may, in its sole discretion
(unless Seller is obligated pursuant to Section 5.2 hereof to use efforts to
cure such untrue, inaccurate or incorrect representation or warranty, in which
case Seller will use such efforts as are required under Section 5.2 hereof to
cure such untrue, inaccurate or incorrect representation or warranty), elect by
notice to the Purchaser to adjourn the Closing one or more times for up to sixty
(60) days in the aggregate in order to cure or correct such untrue, inaccurate
or incorrect representation or warranty provided, however, that Seller may not
adjourn the Closing beyond June 30, 1999. If any such representation or warranty
is not cured or corrected by the Seller on or before the Closing Date (whether
or not the Closing is adjourned as provided above), then the Purchaser, as its
sole remedy for such inability of Seller, shall elect either (i) to waive such
misrepresentations or breaches of warranties and consummate the transactions
contemplated hereby without any reduction of or credit against the Purchase
Price, or (ii) to terminate this Agreement by notice given to Seller pursuant to
the provisions of Section 14.1. In the event the Closing occurs, the Purchaser
hereby expressly waives, relinquishes and releases any right or remedy available
to it at law, in equity or under this Agreement to make a claim against the
Seller for damages that the Purchaser may incur, or to rescind this Agreement
and the transactions contemplated hereby, as the result of any of the Seller's
representations or warranties being untrue, inaccurate or incorrect if the
Purchaser knew, should have known or is deemed to have known that such
representation or warranty was untrue, inaccurate or incorrect at the time of
the Closing and the Purchaser nevertheless closes title hereunder.

         6.3   LIMITED NATURE OF REPRESENTATIONS.

         The Purchaser acknowledges that neither the Seller nor any of the
Seller's Affiliates, nor any of their agents or representatives, nor Broker has
made any representations or held out any inducements to the Purchaser other than
those specifically set forth in this Section 6 and Section 11. The Purchaser
acknowledges that the Seller, pursuant to the terms of this Agreement, has
afforded or will afford the Purchaser the opportunity for full and complete
investigations, examinations and inspections of the Property and all Property
Information. The Purchaser acknowledges and agrees that (i) the Property
Information delivered or made available to the Purchaser and the Purchaser's
Representatives by the Seller or the Seller's Affiliates, or any of their agents
or representatives may have been prepared by third parties and may not be the
work product of the Seller and/or any of the Seller's Affiliates; (ii) neither
the Seller nor any of the Seller's Affiliates has made any independent
investigation or verification of, or has any knowledge of, the accuracy or
completeness of, the Property Information; (iii) the Purchaser is relying solely
on its own investigations, examinations and inspections of the Property and
those of the Purchaser's Representatives and is not relying in any way on the
Property Information furnished by the Seller or any of the Seller's Affiliates,
or any of their agents or representatives, except to the extent of any
representations or warranties expressly set forth in Section 6(a)-(h) of this
Agreement specifically with regard to such Property Information; and (iv) except
as may be expressly set forth in Section 6(a)-(h) of this Agreement specifically
with regard to such Property Information, the Seller expressly disclaims any
representations or warranties with respect to the accuracy or completeness of
the Property Information, and the Purchaser releases the Seller and the Seller's
Affiliates, and

their agents and representatives, from any and all liability with respect
thereto. The Purchaser or anyone claiming by, through or under the Purchaser,
hereby fully and irrevocably releases the Seller and the Seller's Affiliates
from any and all claims that it may now have or hereafter acquire against any of
the Seller or the Seller's Affiliates for any cost, loss, liability, damage,
expense, action or cause of action, whether foreseen or unforeseen, arising from
or related to the presence of environmentally hazardous, toxic or dangerous
substances, or any other conditions (whether patent, latent or otherwise)
affecting the Property, except for claims against the Seller based upon any
obligations and liabilities of the Seller expressly provided in this Agreement.

         The provisions of this Section 6 shall survive the Closing.

         agreement to which the Purchaser or any of its assets are subject or
         bound and will not result in a violation of any Laws applicable to the
         Purchaser.

         actions, suits, proceedings or investigations to which the Purchaser is

         Between the date hereof and the Closing Date, the Seller shall continue
to operate and maintain the Property in accordance with its customary practice.

         10.1  NEW LEASES; ALTERATION OF LEASE.

         From and after the date hereof until the Closing Date or the earlier
termination of this Agreement, the Seller shall not enter into any new lease
with respect to the Property or alter the Lease without the prior written
consent of the Purchaser. The Seller shall not enter into any new lease with
respect to the Property which is contingent upon the termination of this
Agreement.

         10.2  TERMINATION OF LEASE.

         Notwithstanding anything to the contrary contained in this Agreement,
the Seller reserves the right, but is not obligated, to institute summary
proceedings against the tenant under the Lease or terminate the Lease as a

Seller makes no representations and assumes no responsibility with respect to
(i) the continued occupancy of the Property or any part thereof by the tenant
under 
<PAGE>   24
the Lease and (ii) the fulfillment by such tenant of its obligations under the
Lease. The removal of such tenant whether by summary proceedings or otherwise
prior to the Closing Date shall not give rise to any claim on the part of the
Purchaser. Further, the Purchaser agrees that it shall not be grounds for the
Purchaser's refusal to close this transaction that such tenant is a holdover
tenant or in default under its Lease pursuant to any economic or non-economic
terms of the Lease on the Closing Date and the Purchaser shall accept title
subject to such holding over or default without credit against, or reduction of,
the Purchase Price.

         10.3  INSURANCE.

         Until the Closing, Seller shall maintain, or cause the tenant under the
Lease to maintain, insurance on the Property in accordance with the terms of the
Lease.

11.      BROKER.

         The Purchaser and the Seller represent and warrant to each other that
John Power, David Fitzgerald and Phil Giunta of CB Richard Ellis Whittier
Partners (collectively, the "Broker") is the sole broker with whom they have
dealt in connection with the Property and the transactions described herein. The
Purchaser shall be liable for, and shall indemnify the Seller against, all
brokerage commissions or other compensation due to John Power and David
Fitzgerald arising out of the transaction contemplated in this Agreement, which
compensation shall be paid subject and pursuant to a separate agreement between
the Purchaser and the Broker. The Seller shall be liable for and shall indemnify
the Purchaser against, all brokerage commissions or other compensation due to
Phil Giunta arising out of the transaction contemplated in this Agreement, which
compensation shall be paid subject and pursuant to a separate agreement between
Seller and Broker. Each party hereto agrees to indemnify, defend and hold the
other harmless from and against any and all claims, causes of action, losses,
costs, expenses, damages or liabilities, including reasonable attorneys' fees
and disbursements, which the other may sustain, incur or be exposed to, by
reason of any claim or claims by any broker, finder or other person, except (in
the case of the Purchaser as indemnitor hereunder) the Broker, for fees,
commissions or other compensation arising out of the transactions contemplated
in this Agreement if such claim or claims are based in whole or in part on
dealings or agreements with the indemnifying party. The obligations and
representations and warranties contained in this Section 11 shall survive the
termination of this Agreement and the Closing.

12.      CASUALTY; CONDEMNATION.

         12.1  DAMAGE OR DESTRUCTION.

         If a "material" part (as hereinafter defined) of the Property is
damaged or destroyed by fire or other casualty whether insured or uninsured,
intentional or unintentional, the Seller shall notify the Purchaser of such fact
and the Purchaser shall have the option to terminate this Agreement upon notice
to the Seller given not later than ten (10) days after receipt of the Seller's
notice; provided, however, that the Purchaser's election shall be ineffective if
within ten (10) days after the Seller's receipt of the Purchaser's election
notice, the Seller shall elect 
<PAGE>   25
by notice to the Purchaser to repair such damage or destruction and shall
thereafter complete such repair by the earlier to occur of (i) 90 days after the
then scheduled Closing Date at the time of the Purchaser's election; or (ii)
June 30, 1999. If the Seller makes such election to repair, the Seller shall
have the right to adjourn the Closing Date one or more times for up to 90 days
in the aggregate, provided, however, that the Seller may not extend the Closing
Date beyond June 30, 1999, in order to complete such repairs and shall have the
right to retain all insurance proceeds which the Seller may be entitled to
receive as a result of such damage or destruction. If (i) the Purchaser does not
elect to terminate this Agreement as to the damaged Property, (ii) the Purchaser
elects to terminate this Agreement as to the damaged Property but such election
is ineffective because the Seller elects to repair such damage and completes
such repair within such time period provided above (which period shall not
extend beyond June 30, 1999), or (iii) there is damage to or destruction of an
"immaterial" part ("immaterial" is herein deemed to be any damage or destruction
which is not "material", as such term is hereinafter defined) of the Property,
the Purchaser shall close title as provided in this Agreement and, at the
Closing, the Seller shall, unless the Seller has repaired such damage or
destruction prior to the Closing which repair shall be subject to Purchaser's
reasonable approval, (x) pay over to the Purchaser the proceeds of any insurance
collected by the Seller less the amount of all costs incurred by the Seller in
connection with the repair of such damage or destruction, and (y) assign and
transfer to the Purchaser all right, title and interest of the Seller in and to
any uncollected insurance proceeds which the Seller may be entitled to receive
from such damage or destruction, provided, however, if the cost of repairing
such damage or destruction is equal to or greater than Twenty Five Thousand
Dollars ($25,000.00) and equal to or less than Two Hundred and Fifty Thousand
Dollars ($250,000.00), in the reasonable estimation of a third party contractor
mutually agreed upon by Seller and Purchaser, then (xx) Seller shall repair such
damage or destruction to the reasonable satisfaction of Purchaser on or before
the scheduled Closing Date; or (yy) Seller shall have a reduction in the
Purchase Price at Closing equal to the cost of the repair of such damage or
destruction (as estimated by such third party contractor) and Seller shall
retain any insurance proceeds relevant to such damage or destruction. A
"material" part of the Property shall be deemed to have been damaged or
destroyed if the cost of repair or replacement shall be ten percent (10%) or
more of the Purchase Price.

         12.2  CONDEMNATION.

         If, prior to the Closing Date, all or any "significant" portion (as
hereinafter defined) of the Property is taken by eminent domain or condemnation
(or is the subject of a pending taking which has not been consummated), the
Seller shall notify the Purchaser of such fact and the Purchaser shall have the
option to terminate this Agreement upon notice to the Seller given not later
than ten (10) days after receipt of the Seller's notice. If the Purchaser does
not elect to terminate this Agreement, or if an "insignificant" portion
("insignificant" is herein deemed to be any taking which is not "significant",
as such term is herein defined) of the Property is taken by eminent domain or
condemnation, at the Closing the Seller shall assign and turnover, and the
Purchaser shall be entitled to receive and keep, all awards or other proceeds
for such taking by eminent domain or condemnation. A "significant" portion of
the Property means (i) 10% or more of the main office building on the Land, (ii)
a portion of the parking areas if 
<PAGE>   26
the taking thereof reduces the remaining available number of parking spaces
below the minimum legally required, or (iii) a legally required driveway on the
Land if such driveway is the predominant means of ingress thereto or egress
therefrom.

         12.3  TERMINATION.

         If the Purchaser effectively terminates this Agreement pursuant to
Section 12.1 or 12.2, this Agreement shall be terminated and the rights of the
parties shall be the same as if notice of termination were given pursuant to
Section 14.1.

13.      CONDITIONS PRECEDENT TO CLOSING.

         13.1  CONDITIONS PRECEDENT TO THE PURCHASER'S OBLIGATIONS TO PERFORM.

         Subject to Section 13.3, the Purchaser's obligation under this
Agreement to purchase the Property is subject to the fulfillment of each of the
following conditions: (i) the representations and warranties of the Seller
contained herein shall be materially true, accurate and correct as of the
Closing Date except to the extent they relate only to an earlier date; (ii) the
Seller shall be ready, willing and able to deliver title to the Property in

all other covenants, undertakings and obligations, and complied with all
conditions required by this Agreement to be performed or complied with by the
Seller at or prior to the Closing.

         13.2 CONDITIONS PRECEDENT TO THE SELLER'S OBLIGATIONS TO PERFORM.

         The Seller's obligation under this Agreement to sell the Property to
the Purchaser is subject to the fulfillment of each of the following conditions:
(i) the representations and warranties of the Purchaser contained herein shall
be materially true, accurate and correct as of the Closing Date; (ii) the
Purchaser shall have delivered the funds required hereunder and all the
documents to be executed by the Purchaser set forth in Section 9 and shall have
performed all other covenants, undertakings and obligations, and complied with
all conditions required by this Agreement to be performed or complied with by
the Purchaser at or prior to the Closing; and (iii) the additional matters set
forth in Schedule 8 annexed hereto and made a part hereof shall have occurred or
been delivered to the Seller, as applicable, at or prior to the Closing.

         13.3  CONDITIONS PRECEDENT TO PURCHASER'S AND SELLER'S OBLIGATIONS TO 
PERFORM REGARDING ENVIRONMENTAL MATTERS.

                  (a) The Purchaser's obligation under this Agreement to
         purchase the Property is subject to the Seller, at Purchaser's sole
         cost, having caused Haley & Aldrich, or another environmental
         consulting firm approved by Purchaser, which 
<PAGE>   27
         approval shall not be unreasonably withheld, to perform the work set
         forth in the Scope of Work for Subsurface Investigations, dated
         November 13, 1998 and prepared by Haley & Aldrich, attached hereto as
         Exhibit L (the "Scope of Work"). Seller shall furnish to the Purchaser
         copies of all test results relating to the work conducted pursuant to
         the Scope of Work ("Seller's Test Data") promptly after Seller's
         receipt of same. Purchaser or anyone claiming by, through or under the
         Purchaser, hereby fully and irrevocably releases the Seller and the
         Seller's Affiliates from any and all claims, costs, losses, expenses,
         actions or causes of action that it may now have or hereafter acquire
         against the Seller or Seller's Affiliates with respect to the accuracy
         or completeness of any such studies or reports delivered to Purchaser
         by Seller.

                  (b) Within forty-five (45) days of providing the Purchaser
         with Seller's Test Data, the Seller's LSP shall determine (x) whether a
         Class A or Class B RAO, with or without an AUL, as set forth in Section
         8(o) of this Agreement, may be obtained without having to perform
         additional response action (as defined in MCP) beyond that which is
         described in the Scope of Work, and (y) whether such RAO may be
         achieved within three (3) years of the Closing Date. In the event that
         the Seller's LSP, in its reasonable discretion, determines that a RAO
         may not be obtained in strict accordance with the terms and conditions
         set forth in the immediately preceding sentence, the Seller may, at its
         sole option, terminate this Agreement by providing the Purchaser with
         written notice of its election to terminate this Agreement within the
         forty-five (45) day period set forth in the immediately preceding
         sentence; thereafter, the Seller and the Purchaser shall have their
         respective rights and obligations set forth in Section 14.1. In the
         event that the Seller does not elect to terminate this Agreement
         pursuant to the above provisions, the Seller shall provide the
         Purchaser with a plan setting forth a description of any actions,
         including any response actions, required to obtain a Class A or Class B
         RAO at the Property ("Seller's Response Plan"). Seller's obligations
         pursuant to Section 8(o) shall be deemed fulfilled if (xx) Purchaser's
         LSP, together with Seller's LSP, agree, in their respective reasonable
         discretion, that there is a substantial likelihood that the completion
         of Seller's Response Plan will support the filing of a Class A or Class
         B RAO in strict accordance with the requirements set forth in the first
         sentence of this Section 13.3(b); and (yy) Seller has placed in an
         interest bearing escrow account (the "Response Plan Account") created
         pursuant to an escrow agreement which shall be mutually acceptable to
         both the Seller and the Purchaser, an amount equal to 125% of the total
         costs estimated and agreed upon between Seller's LSP and Purchaser's
         LSP to conduct the response actions set forth in Seller's Response
         Plan. Interest on the funds deposited in the Response Plan Account
         shall be property of the Seller and paid to the Seller on a monthly
         basis. After a Class A or Class B RAO has been obtained at the
         Property, any funds remaining in the Response Plan Account shall be
         disbursed to the Seller. In the event that Purchaser's LSP and Seller's
         LSP do not agree that there is a substantial likelihood that the
         completion of Seller's Response Plan will support the filing of Class A
         or Class B RAO in strict accordance with the requirements set forth in
         the first sentence of this Section 13.3(b), Purchaser may terminate
         this Agreement by providing Seller with written notice of such
         disagreement within thirty (30) days of Purchaser's receipt of Seller's
         Response Plan; thereafter, the 
<PAGE>   28
         Purchaser and the Seller shall have their respective rights and
         obligations as set forth in Section 14.1. Notwithstanding anything
         contained in this Section 13.3 to the contrary, at any time at which
         this Agreement allows the Seller to terminate the Agreement, Purchaser
         may, by providing the Seller with written notice within ten (10) days
         of receipt of Seller's termination, elect to waive all conditions of
         Closing related to environmental matters and close the transaction as
         provided for in Section 1.2 above. In such event, all of Seller's
         obligations pursuant to this Section 13.3 including, without
         limitation, the obligation to prepare and perform Seller's Response
         Plan and fund the Response Plan Account, shall terminate and be of no
         further force and effect.

         13.4  REMEDIES UPON FAILURE TO SATISFY CONDITIONS.

         In the event that any condition contained in Sections 13.1, 13.2 or
13.3 is not satisfied, the party entitled to the satisfaction of such condition
as a condition to its obligation to close title shall have as its sole remedy
hereunder the right to elect to (i) waive such unsatisfied condition whereupon
title shall close as provided in this Agreement or (ii) proceed as provided in
Section 14 hereof.

14.      REMEDIES.

         14.1  SELLER'S INABILITY TO PERFORM.

         If the Closing fails to occur by reason of the Seller's inability to
perform its obligations under this Agreement which has not been waived pursuant
to Section 13.3, then the Purchaser, as its sole remedy for such inability of
the Seller, may terminate this Agreement by notice to the Seller. The Seller
shall be deemed to have an inability to perform its obligations hereunder if
Seller has used all efforts expressly required pursuant to the terms of this
Agreement and nonetheless is unable to perform its obligations hereunder. If the
Purchaser elects to terminate this Agreement, then this Agreement shall be
terminated and neither party shall have any further rights, obligations or
liabilities hereunder, except as otherwise expressly provided herein
(collectively, the "Surviving Obligations"), and except that the Purchaser shall
be entitled to a return of the Deposit provided the Purchaser is not otherwise
in default hereunder. Except as set forth in this Section 14.1, the Purchaser
hereby expressly waives, relinquishes and releases any other right or remedy
available to it at law, in equity or otherwise by reason of the Seller's
inability to perform its obligations hereunder. Notwithstanding anything to the
contrary herein, if the Seller's inability to perform its obligations under this
Agreement is a result of any action of, or failure to act by, the Purchaser or
any of the Purchaser's Representatives, the Purchaser shall not be relieved of
its obligations under this Agreement and Purchaser shall not be entitled to any
right or remedy provided in this Section 14.1 or elsewhere in this Agreement.

         14.2  PURCHASER'S FAILURE TO PERFORM.

         In the event of a default hereunder by the Purchaser or if the Closing
fails to occur by reason of the Purchaser's failure or refusal to perform its
obligations hereunder, then the Seller may terminate this Agreement by notice to
the Purchaser. Purchaser shall be deemed to have 
<PAGE>   29
failed to perform its obligations hereunder if Purchaser has intentionally not
used all efforts expressly required pursuant to the terms of this Agreement and
such intentional failure has resulted in Purchaser not being able to fulfill its
obligations hereunder. If the Seller elects to terminate this Agreement, then
(i) this Agreement shall be terminated; (ii) the Seller shall retain the
Downpayment as liquidated damages, as Seller's sole remedy at law or in equity
(subject to the immediately following sentence) for all loss, damage and
expenses suffered by the Seller, it being agreed that the Seller's damages are
impossible to ascertain, and neither party shall have any further rights,
obligations or liabilities hereunder, except for the Surviving Obligations; and
(iii) all interest on the Downpayment shall be disbursed by the Escrow Agent to
the Purchaser. Nothing contained herein shall limit or restrict the Seller's
ability to pursue any rights or remedies it may have against the Purchaser with
respect to the Surviving Obligations. Except as set forth in this Section 14.2
and the Surviving Obligations, the Seller hereby expressly waives, relinquishes
and releases any other right or remedy available to them at law, in equity or
otherwise by reason of the Purchaser's default hereunder or the Purchaser's
failure or refusal to perform its obligations hereunder. Notwithstanding
anything to the contrary herein, if the Purchaser's default or the Purchaser's
failure or refusal to perform its obligations under this Agreement is a result
of any action of, or failure to act by, the Seller or any of the Seller's
Affiliates, the Seller shall not be relieved of its obligations under this
Agreement and the Seller shall not be entitled to any right or remedy provided
in this Section 14.2 or elsewhere in this Agreement.

         14.3  SELLER'S FAILURE TO PERFORM.

         If the Closing fails to occur by reason of the Seller's failure or
refusal to perform its obligations hereunder which has not been waived by the
Purchaser, then the Purchaser, as its sole remedy hereunder, may (i) terminate
this Agreement by notice to the Seller or (ii) seek specific performance from
the Seller which shall be Purchaser's sole and exclusive remedy at law and in
equity if sought by Purchaser. As a condition precedent to the Purchaser
exercising any right it may have to bring an action for specific performance as
the result of the Seller's failure or refusal to perform their obligations
hereunder, the Purchaser must commence such an action on or before September 30,
1999. The Purchaser agrees that its failure to timely commence such an action
for specific performance on or before September 30, 1999 shall be deemed a
waiver by it of its right to commence such an action. Notwithstanding anything
to the contrary herein, if the Seller's failure or refusal to perform its
obligations under this Agreement is a result of any action of, or failure to act
by, the Purchaser or any of the Purchaser's Representatives, the Purchaser shall
not be relieved of its obligations under this Agreement and Purchaser shall not
be entitled to any right or remedy provided in this Section 14.3 or elsewhere in
this Agreement.

15.      ESCROW.

         The Escrow Agent shall hold the Downpayment and all interest accrued
thereon, if any (collectively, the "Deposit" which term shall refer to
Downpayment A plus all interest accrued thereon until delivery of Downpayment B
to the Escrow Agent and which term shall refer to Downpayment A, Downpayment B
and all interest accrued thereon after delivery of 
<PAGE>   30
Downpayment B to the Escrow Agent) in escrow and shall dispose of the Deposit
only in accordance with the provisions of that certain Escrow Agreement of even
date herewith by and among the Escrow Agent, the Purchaser and the Seller
relating to the Property (the "Escrow Agreement") in the form of Exhibit H
hereto. Simultaneously with its execution and delivery of this Agreement, the
Purchaser shall furnish the Escrow Agent with its true Federal Taxpayer
Identification Number so that the Escrow Agent may file appropriate income tax
information returns with respect to any interest earned on or credited to the
Deposit. Purchaser, as the party entitled to the economic benefit of the Deposit
representing interest earned on the Downpayment shall be responsible for the
payment of any tax due thereon. The Escrow Agent shall remit interest on the
Downpayment to the Purchaser on a monthly basis or, if the Escrow Agent is
unable to do so, on such periodic basis as the Escrow Agent is able to remit
such payment.

         The provisions of the Escrow Agreement shall survive the termination of
this Agreement and the Closing.

<PAGE>   32
         The Purchaser and Seller, for the benefit of each other, hereby agree

terms, conditions or substance of this Agreement or the transactions
contemplated herein, without first obtaining the written consent of the other
party hereto, which consent may be withheld on the basis of such other party's
review of any such press release. It is understood that the foregoing shall not
preclude either party from discussing the substance or any relevant details of
the transactions contemplated in this Agreement with any of its attorneys,
accountants, professional consultants or potential lenders, as the case may be,
or prevent either party hereto from complying with Laws, including, without
limitation, governmental regulatory, disclosure, tax and reporting requirements.

         17.2  RETURN OF PROPERTY INFORMATION.

Seller shall effect the Exchange through an assignment of this Agreement, or its
rights under this Agreement, to a qualified intermediary; (iii) Purchaser shall
not be required to acquire or hold title to any real property for purposes of
consummating the Exchange; and (iv) Seller shall pay at Closing any additional
costs that would not otherwise have been incurred by Purchaser or Seller had

indemnify Purchaser and hold Purchaser harmless as to any costs, damages or
other liabilities including reasonable attorneys' fees that Purchaser incurs
(other than payment of the purchase price for the exchange property) in
connection with, or as a result of, the like-kind 
<PAGE>   36
exchange, but exclusive of any costs, damages or other liabilities that
