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
subject to examination by, and is required to file reports with, the
Commissioner of Banks of the Commonwealth of Massachusetts (the "Massachusetts
Commissioner"). The Company's banking subsidiaries are USTrust and United States
Trust Company ("USTC"), each headquartered in Boston and each a Massachusetts
trust company, and UST Bank/Connecticut ("UST/Conn"), headquartered in
Bridgeport, a Connecticut trust company. All of the common stock of USTrust,
USTC, and UST/Conn is issued to and owned by the Company. In addition, the
Company owns, indirectly through its banking subsidiaries, all of the
outstanding stock of three active nonbanking subsidiaries, all Massachusetts
corporations: UST Leasing Corporation, UST Data Services Corp. and UST Capital
Corp.
 
     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. 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 in the
New England region.
 
     As of the close of business on December 31, 1994, the Company's total
assets were approximately $1.8 billion and USTrust, the lead bank, had over $1.7
billion or 94% of the Company's consolidated assets.
 
THE SUBSIDIARY BANKS
 
     USTrust and UST/Conn are engaged in a general commercial banking business
and accept deposits which are insured by the Federal Deposit Insurance
Corporation ("FDIC"). USTC, which has full banking powers and accepts deposits
which are insured by the FDIC, focuses its activity on trust and money
management, venture capital and other fee generating businesses. Two of the
Company's banking subsidiaries are located in Massachusetts and one is located
in Connecticut.
 
RECENT DEVELOPMENTS
 
Recent Operating History and Asset Quality Summary
 
     The Company reported net income of $4.75 million, or $0.27 per share for
1994, as compared with a net loss of $20.1 million, or $1.31 per share in 1993.
Non-performing assets at December 31, 1994, consisting of nonaccrual loans,
restructured loans, accruing loans greater than 90 days past due and other real
estate owned, were $84.9 million, down from a level of $110.8 million at
December 31, 1993. Loans measured as substandard by the Company's internal risk
rating system, also declined during the year from a level of $255 million at
December 31, 1993 to $115 million at December 31, 1994. Under the Company's
definition, substandard loans 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. See pages 20 and 24 in Management's
Discussion and Analysis of Financial Condition and Results of Operations.
 
Bank Regulatory Agreements and Orders
 
     In February 1992, USTC and USTrust entered into separate Consent Agreements
and Orders with the FDIC and the Massachusetts Commissioner. The Company also
entered into a written agreement with the Federal Reserve Bank of Boston (the
"FRB-Boston") and the Massachusetts Commissioner in August 1992. Since June
1991, the Company's Connecticut-based banking subsidiary, UST/Conn, has been
operating under a Stipulation and Agreement with the Commissioner of Banks for
the State of Connecticut (the "Connecticut Commissioner"), which agreement was
amended in August 1992, November 1993 and July
 
                                        1
<PAGE>   4
 
1994. (The foregoing are hereinafter collectively referred to as the "Regulatory
Agreements."). In February 1994, the FDIC and the Massachusetts Commissioner
terminated and lifted the Consent Agreement and Order with USTC.
 
     The remaining Regulatory Agreements require that the Company, USTrust and
UST/Conn refrain from paying dividends without prior regulatory consent and the
Company has not paid a cash dividend to its stockholders since July 1991.
Despite the termination of its Regulatory Agreement, USTC has agreed to continue
to request regulatory consent prior to the payment of dividends. The Regulatory
Agreements further require USTrust and UST/Conn to maintain Tier 1 leverage
capital ratios at or in excess of 6%. Each of the Company's subsidiary banks is
in compliance with its respective capital requirements. As provided in the
Regulatory Agreements, the Company, USTrust and UST/Conn have reduced levels of
nonperforming assets and have implemented written plans and policies concerning,
among other matters credit administration, loan review and intercompany
transactions. USTrust and UST/Conn have also revised and expanded their
investment and funds management policies as required by the Regulatory
Agreements. Moreover, the Company has agreed to give the FRB-Boston and the
Massachusetts Commissioner prior notice of certain significant expenditures and
certain increases in management compensation. The Company has filed (and will
continue to file) with the regulatory agencies a broad range of periodic reports
and updated strategic plans. For a discussion of capital in the context of the
Regulatory Agreements, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Capital" on page 18.
 
     In addition to the foregoing, in 1994, UST/Conn entered into an informal
Memorandum of Understanding with the FDIC under the significant terms of which
UST/Conn undertook to: increase the level of Board monitoring of UST/Conn's
Community Reinvestment Act ("CRA") activities and lending data; develop and
implement an improved CRA marketing program; and consider more effective
utilization of available government lending programs and certain other matters.
 
Asset Management Employment Agreements
 
     As of January 1, 1995, the Company and USTC, subject to regulatory
approval, entered into Employment Agreements with five key executives in the
Asset Management Division of USTC. These Employment Agreements are designed: (i)
to induce those key executives to continue in the employ of USTC and to accept
certain non-competition agreements; (ii) to raise the share of Asset Management
Division revenues retained by Management of the Division; (iii) to provide
assurances to those key executives that they will be allowed to continue to
manage the Division with the degree of independence they currently enjoy; and
(iv) to provide strong economic incentives for those executives to increase the
Division's aggregate revenues. Although the foregoing Employment Agreements were
entered into as of January 1, 1995, the revised revenue sharing arrangements
were effective as of July 1, 1994 and were reflected in the previously reported
third and fourth quarter financial results of the Company. Each of the
Employment Agreements provide for two and one-half year original terms
commencing January 1, 1995 and (unless terminated by the employee by giving the
Company and USTC six months prior notice) successive six month renewal terms
thereafter. In the event, however, that a Triggering Event or change in
ownership of USTC or the Company (as defined in the Employment Agreements)
occurs during the original term or a renewal term, a new, approximately
three-year term will be triggered and the key employee will receive in exchange
for an extension of his or her employment period together with the related
noncompetition agreements, a Formula Payment, as defined in the Employment
Agreement, which will be based upon the Asset Management Division's revenues
during the year preceding the Triggering Event. For a further discussion of the
financial impact of these new compensation arrangements, see pages 26 and 27 in
Management's Discussion and Analysis of Financial Condition and Results of
Operations.
 
BUSINESS SERVICES
 
     USTrust and UST/Conn provide commercial banking services, including
deposit, investment, cash management, payroll, wire transfer, leasing and
lending services throughout New England. Commercial and industrial lending takes
the form primarily of direct loans and includes lines of credit, revolving
credits, domestic and foreign letters of credit, term loans, mortgage loans,
receivable, inventory and equipment loans
 
                                        2
<PAGE>   5
 
and other specialized lending services. Furthermore, the Company provides
additional services to small business customers through utilization of
government sponsored and assisted loan programs and through the Company's
Minority Enterprise loan program. In 1994, USTrust was certified by the SBA as a
"Small Business Association Lender". USTrust also provides merchant credit card
services. USTC provides deposit services and other banking services, but focuses
its activities on money management, venture capital and other fee generating
services. Through loan participations, each bank is able to provide credit to
businesses in its area up to the limit available to the combined banks. At
December 31, 1994, the combined lending limit to a single borrower of the
subsidiary banks was approximately $29 million.
 
CONSUMER SERVICES
 
     Consumer services are provided by USTrust and UST/Conn to customers in
their respective areas. These services include savings and checking accounts,
NOW and money market accounts, consumer loans, night depositories, credit cards
(through a private label arrangement), safe deposit box facilities and
travelers' checks. In 1994 the Company repriced and added further enhancements
to its Choice Checking retail account product, which combines a relatively
modest fee structure with ancillary travel, insurance and other "lifestyle"
benefits. The Company in 1994 also began offering a basic savings account
service to accompany its basic checking account service, both of which are
designed to serve the needs of individual customers of moderate means. Consumer
loans include residential first mortgage and home equity loans and loans to
finance education costs as well as open-ended credit via cash reserve
facilities. Automobile loans reached a volume of approximately $94 million as of
December 31, 1994. In 1994, the Company's Affordable Mortgage Program, designed
to provide certain customers of USTrust and UST/Conn who may not qualify for
traditional mortgage financing with an alternate means of financing or
refinancing a residence, saw increased volume. The Company's banking
subsidiaries, which currently have an aggregate of 33 banking offices, maintain
an automated teller machine system which through membership in the Cirrus and
InfiNet Payment Services, Inc. networks provides the Company's customers with
access to their accounts at locations throughout the United States. Most of the
Company's ATM machines provide information to customers in three languages,
English, Spanish and Portuguese. The Company provides a broad range of services
in connection with its consumer automobile lending program. The Company's
banking subsidiaries offer an integrated Preferred Banking Services which
combines a wide range of the Company's retail banking products.
 
INVESTMENT SERVICES
 
     The Investment Group located at USTrust and UST/Conn was formed in May
1994. The Investment Group, through Essex National Securities, Inc., an
unaffiliated, licensed broker-dealer, offers mutual funds (whose investments are
managed by nonaffiliated third parties), treasury bills, notes, corporate bonds,
state, federal and municipal bonds and discount brokerage services to the
customers of USTrust and UST/Conn.
 
SPECIALIZED SERVICES FOR INDIVIDUALS
 
     The Company provides services to meet the financial needs of individuals,
such as self-employed professionals, corporate executives and entrepreneurs. The
Company's services include deposit accounts, specialized credit facilities, an
account management system for escrow funds, consumer banking and other personal
financial products.
 
REAL ESTATE SERVICES
 
     USTrust and UST/Conn provide a broad range of industrial and commercial
real estate lending services, residential mortgage banking services and other
related financial services.
 
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, profitsharing
and other employee benefit trusts. At December 31, 1994, the total assets under
management of USTC were
 
                                        3
<PAGE>   6
 
approximately $3.1 billion. See "Recent Developments -- Asset Management
Employment Agreements", above.
 
SECURITIES PORTFOLIOS MAINTAINED BY THE COMPANY
 
     The subsidiary banks maintain securities portfolios consisting primarily of
U.S. Treasury, U.S. Government Agency, corporate and municipal securities.
Essentially 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. USTrust's securities portfolio also
includes certain other equity investments as allowed within limits prescribed by
Massachusetts law. Such investments currently include, among others, equity
interests in the Massachusetts Housing Investment Corporation's Limited
Partnership Equity Fund for Affordable Housing, and in the Massachusetts
Minority Enterprise Corporation. The Treasury Division of the Company provides
securities portfolio advisory services to the Company's affiliated banks.
 
PRINCIPAL NONBANKING SUBSIDIARIES
 
     UST Leasing Corporation, a subsidiary of USTrust organized in 1987,
provides a broad range of equipment leasing services to major corporations
headquartered throughout the United States. In 1994, UST Leasing Corporation
developed 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, 1994, UST Leasing Corporation's total assets were approximately
$26.8 million.
 
     UST Data Services Corp., organized in 1981 and a subsidiary of USTrust,
provides a full range of electronic data processing, deposit and other
operations services to the Company and its affiliates.
 
     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 longterm debt financing for growth-oriented companies.
 
COMPETITIVE CONDITIONS
 
        The Company's banking and nonbanking subsidiaries face substantial
competition throughout Massachusetts and Connecticut. This competition is
provided by commercial banks, savings banks, credit unions, consumer finance
companies, insurance companies, "nonbank banks," money market mutual funds,
government agencies, investment management companies, investment advisors,
brokers and investment bankers. In addition, the Company anticipates increased
competition from out-of-state and foreign banks and bank holding companies as
those entities increase their usage of interstate banking powers granted since
1983 as well as by the September 1994 enactment of the Riegle-Neal Interstate
Banking and Branching Act (discussed under "Supervision and Regulation of the
Company and its Subsidiaries" below). During the past several years, the
closing by regulators of a number of banks and bank holding companies in
Eastern Massachusetts and Connecticut followed, in general, by acquisitions of
small- and medium-sized banks and bank holding companies by the largest New
England bank holding companies, as well as recently somewhat improved economic
conditions within the region have resulted in fewer but financially stronger
competitors in the local markets served by the Company's banking subsidiaries.
 
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, USTC, USTrust and UST/Conn (collectively, the "Subsidiary Banks") are
subject to substantial regulation and supervision by the FDIC and the applicable
state bank regulatory agencies. Such activities are often intended primarily for
the protection of depositors or are 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. 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. Since
 
                                        4
<PAGE>   7
 
1992, the Company and its banking subsidiaries have been operating under
regulatory agreements and orders with state and federal bank regulatory
authorities. In February 1994, the order under which USTC was operating was
lifted and terminated. See "Recent Developments-Bank Regulatory Agreements and
Orders" above.
 
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% 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 affiliated 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 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% 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 commercial banks located in
Massachusetts or in those states which permit acquisitions of banking
institutions located in their states by Massachusetts bank holding companies.
 
     The Connecticut General Statutes require that the Company furnish to the
Connecticut Commissioner such reports as the Connecticut Commissioner deems
appropriate to the proper supervision of the Company. The Connecticut
Commissioner is also authorized to make examinations of the Company and its
Connecticut subsidiaries including UST/Conn, and to order the Company to cease
and desist from engaging in any activity which constitutes a serious risk to the
financial safety, soundness or stability of the Company or UST/Conn, or is
inconsistent with sound banking principles or the provisions of the banking laws
of Connecticut.
 
     The location of nonbank subsidiaries of the Company is not restricted
geographically under the BHC Act. In 1989, after the passage of the Financial
Institutions Reform, Recovery and Enforcement Act of 1989 ("FIRREA"), the
Federal Reserve Board amended its regulations under the BHC Act to permit bank
holding companies, as a nonbanking activity, to own and operate savings
associations without geographical restrictions. Furthermore, in September, 1994,
the Riegle-Neal Interstate Banking and Branching Act of 1994 (the "Interstate
Banking Act") was enacted. The Interstate Banking Act's provisions, among other
things: (i) permit bank holding companies, under certain circumstances, to
acquire control of banks in any state beginning September 28, 1995, subject to
(a) specified maximum national and state deposit concentration limits; (b) any
applicable state law provisions requiring that the acquired bank has to have
been in existence for a specified period of up to 5 years; (c) any applicable
nondiscriminatory state provisions that make an acquisition of a bank contingent
upon a requirement to hold a portion of such bank's assets available for call by
a state sponsored housing entity; and (d) applicable anti-trust laws; (ii)
authorize interstate mergers by banks in different states, including branching
through bank mergers, beginning June 1, 1997, subject to the provisions noted in
(i) and to any state laws that opt in as of an earlier date or opt out of the
provision entirely; (iii) authorize states to enact legislation permitting
interstate de novo branching; and (iv) provide for parity of treatment for
foreign bank branch activities. Proposed legislation has been filed in each of
Massachusetts and
 
                                        5
<PAGE>   8
 
Connecticut which, if enacted, would cause those jurisdictions to "opt-in" prior
to June 1, 1997. The full impact of the Interstate Banking Act will not be clear
until the state legislatures have voted and the banking regulatory agencies have
adopted final regulations.
 
     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 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. The Subsidiary Banks pay
substantial deposit insurance premiums to the FDIC. Such deposit premium rates
were substantially increased in 1992 pursuant to regulations issued under the
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"). In
early 1995, the FDIC proposed that deposit premiums be reduced substantially,
except for banks with the most unfavorable risk profiles. It is too early to
determine whether this proposal will be implemented or what effect it will have
on the Company's earnings.
 
     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 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 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.
 
     The Company and all its subsidiaries are also subject to certain
restrictions with respect to engaging in the issue, flotation, underwriting,
public sale or distribution of certain types of securities. 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, two of which are chartered under Massachusetts law
and one of which is chartered under Connecticut 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 purposes 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.
 
     Under the uniform regulations, a well-capitalized institution has a minimum
tier 1 capital-to-total risk-based assets ratio of 6 percent, a minimum total
capital-to-total risk-based assets ratio of 10 percent and a minimum leverage
ratio of 5 percent and is not subject to any written agreement, order or capital
directive. An adequately capitalized institution meets all of its minimum
capital requirements under the existing capital adequacy guidelines. An
undercapitalized institution is one that fails to meet any one of the three
minimum capital requirements. A significantly undercapitalized institution has a
tier 1 capital-to-total risk-based assets
 
                                        6
<PAGE>   9
 
ratio of less than 3 percent, a tier 1 leverage ratio of less than 3 percent or
a total capital-to-total risk-based assets ratio of less than 6 percent. A
critically undercapitalized institution has a tier 1 leverage ratio of 2 percent
or less. An institution whose capital ratios meet the criteria for a well
capitalized institution may be classified as an adequately capitalized
institution due to qualitative and/or quantitative factors other than capital
adequacy. An adequately capitalized institution or undercapitalized institution,
may under certain circumstances, be required to comply with supervisory action
as it if were in the next lower category.
 
     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. The capital restoration
plan will be accepted only if (i) it specifies the steps that will be taken to
become adequately capitalized and the activities in which the institution will
engage, (ii) it is based upon realistic assumptions and it is likely to succeed
in restoring the institution's capital, (iii) it does not appreciably increase
the institution's risk exposure and (iv) each holding company that controls the
institution provides appropriate assurances of performance and guaranties that
the institution will comply with the plan until the institution is adequately
capitalized on an average basis for each of four consecutive quarters. Liability
under the guaranty is the lesser of (i) five percent of the institution's total
assets at the time it become undercapitalized and (ii) the amount necessary to
bring the institution into compliance with all applicable capital standards as
of the time the institution fails to comply with the 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.
 
     FDICIA requires the appropriate regulatory agencies to take one or more
specific actions against significantly undercapitalized institutions and
undercapitalized institutions that fail to submit acceptable capital restoration
plans, which actions include but are not limited to (i) requiring the
institution to sell shares or other obligations to raise capital, (ii) limiting
deposit interest rates, (iii) requiring the election of a new board of directors
and/or dismissing senior executive officers and directors who held such
positions for more than 180 days before the institution became undercapitalized,
(iv) prohibiting receipt of deposits from correspondent banks, (v) requiring
divestiture or liquidation of one or more subsidiaries and (vi) requiring the
parent company to divest the institution if such divestiture will improve the
institution's financial condition and future prospects. In addition, an insured
institution that receives a less-than-satisfactory rating for asset quality,
management, earnings or liquidity 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 Federal Reserve Board has indicated that it will consult with each
federal banking agency regulating the bank subsidiaries of a holding company to
monitor required supervisory actions, and based upon an assessment of these
developments, will take appropriate action at the holding company level.
 
     Under FDICIA, federal bank regulators are also required to see that changes
are made in the operations and/or management of a bank or bank holding company
if the financial institution is deemed to be "undercapitalized." Under FDICIA, a
depository institution that is "adequately capitalized" but not "well
capitalized" is generally prohibited from accepting brokered deposits and
offering interest rates on deposits higher than the prevailing rate in its
market. In addition, "pass through" insurance coverage may not be available for
certain employee benefit accounts. The Company believes that the application of
these limitations to it would not have a material effect on its funding or
liquidity.
 
     USTC is currently classified as "well capitalized" and USTrust and UST/Conn
are each currently classified as "adequately capitalized".
 
                                        7

     Additional regulations adopted pursuant to FDICIA include: (1) real estate
lending standards for depository institutions, which provide guidelines
concerning loan-to-value ratios for various types of real estate loans; (2)
rules requiring depository institutions to develop and implement internal
procedures to evaluate and control credit and settlement exposure to their
correspondent banks; (3) rules implementing the FDICIA provisions prohibiting,
with certain exceptions, insured state banks from making equity investments or
engaging in activities of the types and amounts not permissible for national
banks; and (4) rules and guidelines for enhanced financial reporting and audit
requirements. Rules currently proposed for adoption pursuant to FDICIA include:
(1) revisions to the risk-based capital guidelines regarding interest rate risk,
concentrations of credit risk and the risks posed by "nontraditional
activities", and (2) rules addressing various "safety and soundness" issues,
including operations and managerial standards, standards for asset quality,
earnings and compensation standards.
 
     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. With the passage
of FIRREA in 1989, the Crime Control Act in 1990 and FDICIA in 1991, federal
bank regulatory agencies including the Federal Reserve Board and the FDIC were
granted substantially broader enforcement powers to restrict the activities of
financial institutions and to impose or seek the imposition of increased 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 Community Reinvestment Act ("CRA"), federal 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 federal regulatory authority considers 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.
USTrust's current CRA rating is "outstanding" and UST/Conn's current CRA rating
is "needs improvement". UST/Conn in 1994 entered into an informal Memorandum of
Understanding concerning CRA matters with the FDIC as described under "Recent
Developments -- Bank Regulatory Agreements and Orders" above. The FDIC has
determined that it will no longer examine USTC, which focuses upon trust and
asset management activities, for CRA compliance. The Massachusetts Commissioner
has continued to examine USTC for CRA compliance, and currently rates USTC
"satisfactory".
 
     On September 23, 1994, the federal Riegle Community Development and
Regulatory Improvement Act of 1994 (the "Community Development Act") was
enacted. The Community Development Act establishes financial and other
assistance for entities involved primarily in community development activities.
The Community Development Act's provisions also make changes in a number of
areas including, among others: (i) increasing restrictions on some types of high
interest loans; (ii) improving small business access to capital; (iii) requiring
federal banking agencies to, among other things, coordinate examinations and
establish uniform regulations and guidelines where appropriate; (iv) simplifying
and expediting the processing and approvals for certain applications; (v)
expanding the exemptions available to a holding company's subsidiary banks with
respect to FDICIA's audit requirements; (vi) adding flexibility to FDICIA's
safety and soundness standards by, among other things, permitting their issuance
as guidelines and allowing banking agencies more discretion in handling
noncompliance; (vii) amending certain requirements on insider loans; (viii)
modifying local residency requirements for national bank directors; (ix)
limiting the applicability of certain real estate settlement procedures; and (x)
extending some management interlocks exemptions. It is anticipated that the
Community Development Act will reduce slightly certain regulatory burdens on
financial institutions, including the Company's subsidiaries.
 
     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. It is impossible to predict whether any of the current proposals
will be adopted and the impact of such adoption on the business of the Company
or its subsidiaries.

     Supervision, regulation and examination of the Subsidiary Banks by the bank
regulatory agencies are not intended for the protection of the Company's
security holders.
 
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 banks, including
nonmember banks such as all three of the Company's banking subsidiaries, 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. The
impact upon the future business and earnings of the Company of prospective
domestic economic conditions, and of the policies of the Federal Reserve Board
as well as other U.S. regulatory authorities, cannot be predicted accurately.
 
     During the period from 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 Company's
subsidiary banks and the Company's collateral position with respect to certain
loans. The New England regional economy improved somewhat in 1994, which aided
the Company's loan workout efforts in 1994. The New England region, however,
still lags behind the economic growth experienced in the other regions of the
United States. Most of the Company's loans outstanding are from borrowers
located in Eastern 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 1994, the Company's exposure to credit risk from
borrowers who had real estate as their primary collateral support, included $426
million of loans. In addition to the foregoing, during the second half of 1994
and early 1995 prevailing interest rates rose substantially. The current
increase and further increases, if any, in the Base Lending Rate used by the
Company's subsidiary banks may have an adverse effect upon the ability of some
borrowers to repay their loans. See "Management's Discussion and Analysis of
Financial Conditions and Results of Operations" below.
 
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.
 
EMPLOYEES
 
     As of December 31, 1994, the Company and its subsidiaries employed
approximately 870 full-time plus part-time people.
 
ITEM 2.  PROPERTIES
 
     USTrust owns a twelve-story brick and steel building constructed in 1915
and located at Government Center, 30-40 Court Street, Boston, Massachusetts. The
banking premises of USTrust, USTC and the offices of the Company and all of its
nonbanking subsidiaries utilize 99.9% of the 89,014 square feet in the building
and the remaining space is leased as offices to one tenant.
 
     The Company currently leases a three-story brick office building of
approximately 37,900 square feet as well as 29,003 square feet in a
recently-constructed adjacent office tower at 141 Portland Street, Cambridge,
Massachusetts, all of which is used by USTrust and UST Data Services Corp.
USTrust also leases approximately 26,080 square feet of space at 25-55 Court
Street, Boston, which is used primarily to house staff
 
                                        9

support services. In 1991, USTC sold the 25-55 Court Street, Boston, building to
a third party, unaffiliated with the Company.
 
     USTrust owns six branch offices in Boston, Milton Village, Norwood,
Randolph, Stoughton and Swampscott, Massachusetts, all of which were acquired by
the Company in 1991 from the Resolution Trust Corporation as part of the
acquisition and assumption of certain assets, deposits and branches of Home
Owners Savings Bank F.S.B. USTrust also owns four branch offices in Canton,
Gloucester, Milton, and Natick, Massachusetts. UST/Conn owns one branch office
in Huntington, Connecticut. UST/Conn also owns a former branch building in
Shelton, Connecticut, which it expects to sell to a non-affiliated third party
in 1995. The remaining branch offices of the Company occupy leased premises.
 
     The 1995 annual leasehold commitment for all premises leased by the
Company's subsidiaries totals approximately $3,955,000, not including expenses
related to tax or maintenance escalation provisions. See Note 14 to the
Company's Consolidated Financial Statements.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     In the ordinary course of operations, the Company and its subsidiaries
become defendants in a variety of judiciary 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.

     Such over-the-counter market quotations reflect inter-dealer prices,
without retail markup, markdown or commission and may not represent actual

     The number of holders of record of common stock of the Company was 2,059 at
January 31,1995.
 
     There were no dividends declared during 1994 and 1993.
 
     Future dividends will depend upon the financial condition and earnings of
the Company and its subsidiaries, their need for funds and other factors,
including applicable government regulations and regulatory consent. See "Recent
Developments -- Bank Regulatory Agreements and Orders" in Part 1, Item 1 above,
and the discussion of capital in Management's Discussion and Analysis of
Financial Condition and Results of Operations below.
 
     In connection with the $20 million senior debt private placement
transaction of August 1986 of which $8 million currently remains outstanding
(see Note 8 to the Notes to Consolidated Financial Statements of the Company),
the Company agreed not to make dividend payments in excess of 60% of cumulative
net earnings since December 31, 1985 plus $7 million. The Company does not
expect that this provision will adversely affect its ability to pay future
dividends which it deems appropriate.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
                    FINANCIAL CONDITION AT DECEMBER 31, 1994
 
INTRODUCTION
 
     During 1994 the Company continued its emphasis on the resolution of problem
assets. As a result, the Company successfully reduced the level of substandard
loans, as measured by the Company's internal risk rating system, by over 50
percent from a level of $255 million at December 31, 1993 to $115 million at
December 31, 1994. See "Credit Quality and Reserve for Possible Loan Losses" on
page 20 of this Form 10-K for a further discussion.
 
     During the period 1990 to 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 Company's subsidiary banks and the
Company's collateral position with respect to certain loans. The New England
regional economy improved throughout 1994 which has aided loan workout efforts.
The region, however, still lags behind the economic growth experienced
nationally.
 
     The local economic factors and the Company's efforts to reduce
nonperforming assets and substandard loans continued to influence the Company's
financial results for 1994; particularly with regard to the provision for
possible loan losses and the high level of expenses associated with foreclosed
assets and loan workout.
 
     This discussion should be read in conjunction with the financial
statements, notes, and tables included elsewhere in this Form 10-K. Certain
amounts reported for prior periods have been reclassified to conform with the
1994 presentation.
 
ASSETS
 
     Total assets at December 31, 1994 were $1.80 billion compared with $2.04
billion a year ago. The Company's loan portfolio decreased 5 percent, or $72.7
million, to $1.27 billion. The decrease reflects a combination of normal
amortization and increased competition for the small-to-middle market credits.
Another factor in the reduction of the loan portfolio was the outflow of problem
loans through collection, chargeoff or third-party refinancing. See "Credit
Quality and Reserve for Possible Loan Losses" herein.
 
     Presently, the Company anticipates a modest growth in earning assets in the
coming year from a combination of business development efforts to expand the
commercial and retail loan portfolios moderated by the continued reduction of
existing problem assets. Funding for asset growth will be provided by deposit
growth achieved through more aggressive pricing and deposit product promotion.

(1) Certain loans for which the principal source of repayment is not real estate
    collateral have been classified as commercial and financial for the 1992
    through 1994 presentations. For 1991 and prior years these loans were
    included in the Real Estate category. Information is not readily available
    to reclassify loans for these years.
 
(2) Lease financing receivables have been included in loans beginning in 1994.
    Prior years have been reclassified.

     Indirect automobile installment loans represent loans purchased without
recourse from automobile dealers. Automobile loans made directly to consumers
are not significant and are included with other consumer loans.
 
     As a result of a 1990 transaction with the Resolution Trust Corporation
("RTC") wherein the Company purchased certain assets and assumed certain deposit
liabilities of a failed savings and loan institution, Home Owners Federal
Savings Bank F.S.B., the Company had $513.6 million of loans held for sale at
December 31, 1990, and, therefore, not included in the above table. All of these
loans were repurchased by the RTC in 1991.

     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 risk rating profile, irrespective of size, requires Senior Lending
Management and Board of Directors approval.
 
Securities
 
     Securities decreased $72.3 million since year-end 1993 to $401.6 million at
December 31, 1994, reflecting the maturity of short-term U. S. Treasury and
Agency securities. At December 31, 1994, securities were principally comprised
of mortgage-backed securities, U. S. Treasury and Agency securities, and
corporate notes.
 
     On December 31, 1993, the Company adopted Statement of Financial Accounting
Standards No. 115 ("SFAS No. 115"), "Accounting for Certain Investments in Debt
and Equity Securities," issued by the Financial Accounting Standards Board. The
Statement addresses the accounting and reporting for debt and equity securities
that have readily determinable market values. According to SFAS No. 115, these
securities must be classified as either held-to-maturity, available-for-sale, or
trading and are reported at either amortized cost or fair value, depending upon
the classification. Refer to Note 1 to the Notes to Consolidated Financial
Statements of this Form 10-K for a further discussion on SFAS No. 115. At
December 31, 1994, the Company's portfolio consisted of $.1 million of
securities held-to-maturity and $401.5 million available-for-sale. At December
31, 1993, all securities were classified in the available-for-sale category. The
application of SFAS No. 115 resulted in a net decrease of $26.9 million to
stockholders' investment in 1994, representing the change from an unrealized
gain of $3.3 million after tax at December 31, 1993 to an unrealized loss of
$23.6 million after tax at December 31, 1994. In light of the size of the
unrealized loss and its current level of taxable income, the Company concluded
that full recognition of the deferred tax amount was not appropriate and as such
limited the amount of the recorded benefit to $5.4 million at December 31, 1994.
The decline in market value reflects the rapid increase in interest rates and
corresponding decline in market prices for bonds, which occurred throughout
1994.
 
     The Company has a policy of purchasing securities primarily rated A or
better by Moody's Investors Services and in U.S. Government securities. Due to
the Tax Reform Act of 1986, and the resulting reduction in their tax-exempt
nature, the Company decided to forego major new investments in its tax-exempt
portfolio. The following table sets forth the book value of the securities owned
by the Company. Data presented for 1994 and 1993 includes securities
available-for-sale at fair value of $401.5 million and $473.9 million,
respectively. Data presented for 1992 includes both the investment portfolio and
securities held for sale.

     These securities are unsecured corporate notes of investment grade. They
carry the normal credit risk associated with such instruments.
 
     All securities carry interest rate risk. Additionally, mortgage-backed
securities carry prepayment risk. See Note 1 to the Notes to Consolidated
Financial Statements, "Summary of Significant Accounting Policies" on page 36 of
this Form 10-K for a discussion of prepayment risk.
 
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 the maturity or sale of an entity's assets, such as loans
and securities available-for-sale, liability sources such as increased deposits
and purchased or borrowed funds, and access to the capital markets. While the
Company's security portfolio is currently classified almost entirely as
available-for-sale, the Company has no present intention or need to sell any of
its securities or existing loan portfolio, other than a nominal volume of
fixed-rate residential mortgage loans sold to investors as they are originated.
 
     At December 31, 1994, liquidity, which includes excess cash, excess funds
sold and unpledged securities, totaled approximately $259 million, or 14% of
total assets, a $51 million decrease from 1993.
 
     The funds needed to support the Company's loan and securities portfolios
are provided through a combination of commercial and retail deposits and
short-term borrowings. Total deposits decreased $150 million, or 9%, to $1.5
billion since December 31, 1993. Approximately 97% of the decline occurred in
savings and time deposits. For most of 1994, rate-conscious investors utilized
mutual funds and other nonbank
 
                                       16
<PAGE>   19
 
vehicles to obtain higher rates of return but began to take advantage of the
bank's competitive certificate of deposit rates by the end of the year.
 
     As shown in the Consolidated Statements of Cash Flows, cash and cash
equivalents increased $2.9 million during 1994. Cash provided by operations
resulted largely from net interest income from loans and securities, less the
net difference of noninterest expense over noninterest income. Cash provided by
investing activities was due principally to the net decreases in short-term
investments, net decreases in loans through repayment, and to an excess of
proceeds from sales and maturities of securities over securities purchases. Cash
used for financing activities was primarily the result of decreases in both
demand deposits and certificates of deposit and a net decrease in short-term
borrowings.
 
     At December 31, 1994, the parent company had $16 million in securities
available-for-sale. This balance reflects the investment of proceeds received
from the sale of 2.87 million shares of the Company's common stock to more than
sixty institutional investors in a European offering made under Regulation S of
the United States Securities and Exchange Commission on August 12, 1993. These
investments were reduced from $21 million to $16 million during 1994 as the
Company paid its third annual principal installment of $4 million and accrued
interest on its 8.5% Senior Notes.
 
     For the year ended December 31, 1994, the Company received a total of $3
million in dividends from its asset management and trust subsidiary, United
States Trust Company ("USTC"). During the same period $4.9 million was
contributed to UST Bank/Connecticut ("UST/Conn") and $500 thousand was
contributed to USTrust by the Company to supplement their respective equity
capital accounts.

INTEREST RATE RISK
 
     Volatility in interest rates requires the Company to manage interest rate
risk which arises from differences in the timing of repricing of assets and the
liabilities. Management monitors and adjusts the difference between
interest-sensitive assets and interest-sensitive liabilities ("GAP" position)
within various
 
                                       17
<PAGE>   20
 
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
18% of total assets. The Company manages its interest rate GAP primarily by
lengthening or shortening the maturity structure of the Company's securities
portfolio.
 
     The Company's GAP presentation may not reflect the degrees to which
interest-earning assets and core deposit costs respond to changes in market
interest rates. The Company's rate-sensitive assets consist primarily of loans
tied to the prime rate. As interest rates rose during 1994, the prime rate and,
therefore, the Company's yield on earning assets increased faster than the rate
paid on interest-bearing liabilities.
 
     The following table summarizes the Company's GAP position at December 31,
1994. The majority of loans are included in 0-30 days as they reprice in
response to changes in the interest rate environment. Interest-bearing deposits
are classified according to their expected interest rate sensitivity. Actual
sensitivity of these deposits is reviewed periodically and adjustments are made
in the Company's GAP analysis that management deems appropriate. Securities and
noninterest-bearing demand deposits are categorized according to their expected
lives based on published industry prepayment estimates in the case of securities
and current management estimates for demand 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,
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, 1994,
the one-year cumulative GAP position was slightly positive at $50 million, or
approximately 3% of total assets.
 
     During the fourth quarter of 1994, management reclassified certain deposit
liabilities from 0-30 days to periods greater than 30 days. The effect of this
reclassification was an increase in cumulative GAP and higher percentages of
total assets for all periods presented.

CAPITAL
 
     There are three capital requirements which banks and bank holding companies
must meet. Two requirements take into consideration risks inherent in assets for
both on-balance and off-balance sheet items on a risk weighted basis
("risk-based assets"). Risk weightings are as determined by banking regulators
for the industry as a whole. 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% and 8%,
 
                                       18
<PAGE>   21
 
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%. While the Company has not been notified of a specific requirement
above the minimum, two of the Company's banking subsidiaries are required under
regulatory agreements to maintain, and in fact have, over 6% Tier 1 leverage
capital. Those two banking subsidiaries comprise almost all of the consolidated
assets of the Company. See discussion below concerning capital requirements for
the Company and its banking subsidiaries resulting from regulatory agreements.
 
     At December 31, 1994 and 1993, the Company's consolidated risk-based assets
were $1.52 billion and $1.64 billion, respectively. The capital ratios and
regulatory minimum requirements applicable to the Company were:

</TABLE>
 
     Capital ratios have been calculated consistent with regulatory policy which
excludes the impact of SFAS No. 115 and the recording of an unrealized gain/loss
on securities available-for-sale. However, as required, any net unrealized loss
on marketable equity securities has been deducted from Tier 1 capital.
 
     Effective August 3, 1992, UST Corp. entered into a written agreement with
the FRB-Boston and the Massachusetts Commissioner which requires the Company to
maintain Tier 1, Total risk-based and Tier 1 leverage capital ratios which
conform to the Capital Adequacy Guidelines of the Board of Governors of the
Federal Reserve System, and which take into account the current and future
capital requirements of the subsidiary banks, without specifying a numeric
minimum for the Tier 1 leverage capital ratio. The Company believes its
consolidated ratios meet the required minimums.
 
     Additionally, per this agreement, the Company has agreed not to pay any
dividends to stockholders, nor take any dividends from its banking subsidiaries,
without prior regulatory approval. Similarly, the banking subsidiaries in
agreements with their primary regulators have agreed to refrain from
transferring funds in the form of dividends to the Company without prior
regulatory approval. See "Recent Developments -- Bank Regulatory Agreements and
Orders," page 1. The FDIC and Massachusetts Commissioner terminated and lifted
the Consent Agreement and Order with USTC in February 1994; however, USTC has
agreed to continue to request regulatory consent prior to the payment of
dividends. As previously mentioned in this Form 10-K, regulatory approval was
obtained for dividends to the Company of $3 million from USTC and the Company's
capital contribution of $4.9 million to UST/Conn and $500 thousand to USTrust.

the Company's subsidiary banks at December 31, 1994 and 1993 were:

     In February 1992, the Company's two Massachusetts-based banking
subsidiaries, USTC and USTrust, each entered into a Consent Agreement and Order
with the FDIC and the Massachusetts Commissioner. In accordance with these
agreements, the banks agreed to, among other things, maintain a Tier 1 leverage
capital ratio at or in excess of 6% by February 1993. In February 1994, the FDIC
and Massachusetts Commissioner terminated and lifted the Consent Agreement and
Order with USTC. Since June 1991, the Company's Connecticut-based banking
subsidiary, UST/Conn, has been operating under a Stipulation and Agreement with
the Commissioner of Banks for the State of Connecticut. This agreement was
amended in August 1992, November 1993 and July 1994 and requires UST/Conn to
maintain a 6% Tier 1 leverage capital ratio.
 
     Recent amendments to risk-based capital guidelines will affect the amount
of deferred tax assets that may be included in Tier 1 capital for risk-based and
leverage capital purposes. Under the new rule, which becomes effective April 1,
1995, deferred tax assets would be limited to the amount that an institution
expects to realize within one year, or 10% of Tier 1 capital, whichever is less.
The Company's consolidated Tier 1, Total risk-based capital and leverage capital
ratios at December 31, 1994 would be unaffected by this new regulation. The
revised regulation would have an insignificant effect on the Tier 1 leverage
capital ratios of USTrust and USTC. Earlier this year UST/Conn's FDIC and state
regulators indicated that the bank should be using the more stringent
calculation which the December 31, 1994 numbers above reflect.
 
     The Company and each of its subsidiary banks are currently in compliance
with their respective capital requirements under these regulatory agreements.
 
CREDIT QUALITY AND RESERVE FOR POSSIBLE LOAN LOSSES
 
     In 1993 a strategy was adopted which recognized that many troubled credit
situations will need to be handled in an expeditious manner in order to reduce
the management and staff involvement and, in some cases, carrying costs of these
workouts. This would allow the Company's resources to be redirected toward new
business. It would increase the up-front cost of the workouts, however. As a
result, the company recorded a $64.3 million provision for possible loan losses
in that year. Included in that amount was a special provision of $30 million
recorded in the second quarter of 1993. This special provision was management's
estimate of the additional losses to be incurred from the strategic change
referred to above, the continued sluggish economic climate and losses to be
recorded during the remainder of 1993 on these and other credits as a result of
recent events or new facts.
 
     In 1994 the Company continued with its strategy to reduce the level of
problem credits while maintaining its reserve for possible loan losses position.
Net chargeoffs for the year were $23.7 million which were almost entirely
matched by provisions to the loan loss reserve. As a result, the reserve for
possible loan losses decreased only slightly to $61.9 million and equaled 4.9%
of loans outstanding, 126% of nonaccrual loans and 73% of total nonperforming
assets compared with 4.7%, 127% and 56%, respectively, a year ago. Total
nonperforming assets were reduced $25.9 million to $84.9 million, primarily as a
result of a lower level of troubled debt restructurings.
 
     Loans classified as Substandard, Doubtful or Loss, as determined by the
Company in its internal credit risk rating profile, were $115 million at
December 31, 1994 compared with $255 million a year ago, a decrease of $140
million. Loans classified as Substandard and Doubtful were $96 million and $19
million, respectively, at year-end 1994 and no loans were classified as Loss.
The level of loans in these categories and their total are an important factor
in the Company's analysis of the adequacy of its reserve for possible loan
losses. Under the Company's definition, Substandard loans are characterized by
the distinct possibility that some loss will be sustained if the credit
deficiencies are not corrected. The Substandard classification, however, does
not necessarily imply ultimate loss for each individual loan so classified.
Loans classified as Doubtful have all the weaknesses inherent in Substandard
loans with the added characteristic that the weaknesses make collection of 100
percent of the assets questionable and improbable.
 
     As of year end 1994, approximately 70 percent of loans classified as
Substandard or Doubtful were collateralized with real estate, and the remainder
were collateralized with accounts receivable, inventory, equipment and other
business assets. Of the loans secured by real estate, approximately 55 percent
were collateralized by commercial real estate development, approximately 30
percent by owner-occupied commer-
 
                                       20
<PAGE>   23
 
cial properties and approximately 10 percent by residential real estate. The
remaining loans were collateralized by real estate under construction and raw
land.

---------------
(1) The amount of interest on December 31, 1994 nonaccrual and restructured
    loans that would have been recorded had the loans been paying in accordance
    with their original terms during 1994 was approximately $6,259,000. The
    amount of interest income on these loans included in net income in 1994 was
    approximately $3,188,000.
 
(2) Other real estate owned ("OREO") represents assets to which title to the
    collateral has been taken through foreclosure or in-substance. Other real
    estate owned is recorded at the lower of the recorded investment in the loan
    or fair value minus estimated costs to sell ("net realizable value"). Prior
    to 1992, other real estate owned was recorded at the lower of recorded
    investment in the loan or fair value. Included in OREO are automobiles owned
    which are vehicles repossessed for reason of nonpayment. The balance is
    stated at the lower of the recorded investment in the loan or net realizable
    value.
 
(3) Restructured loans are those where interest rates and/or principal
    repayments have been restructured to defer or reduce payment as a result of
    financial difficulties of the borrower.
 
(4) Prior to December 1992, when the Company adopted AICPA Statement of Position
    92-3, OREO was reduced to its fair value by direct charges to the asset.
    Since then, the Company, like other bank holding companies, has used
    reserves to indicate the net realizable value of its OREO.
 
                                       21
<PAGE>   24
 
     At December 31, 1994, in addition to loans on nonaccrual, loans over 90
days and accruing, troubled debt restructurings and other real estate owned, $67
million of accruing commercial and real estate loans, of which, 99 percent were
current, have nonetheless been classified as Substandard in the Company's
internal risk rating profile. This compares with $206 million a year ago.
 
     Also, at December 31, 1994 loans rated Special Mention in the Company's
internal risk rating profile amounted to $16 million, of which 96 percent were
current. This compares with $30 million a year ago. 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. There were no loans
classified Doubtful that were not disclosed in the above table.
 
     Adverse economic conditions in the future could result in further
deterioration of the Company's loan portfolio and the value of its OREO
portfolio. Such conditions would also likely result in increases in
delinquencies, nonperforming assets, restructured loans, and OREO writedowns
which individually or collectively could have a material negative effect on
future earnings through reduced interest income, increased provisions for
possible loan losses, and higher costs to collect loans and maintain repossessed
collateral.
 
CREDIT QUALITY MONITORING
 
     Credit quality within the commercial and commercial real estate loan
portfolios of each subsidiary is quantified by a corporate credit rating system
designed to parallel regulatory criteria and categories of loan risk. Lenders
monitor their loans to ensure appropriate rating assignments are made on a
timely basis. Risk ratings and overall loan quality are also assessed on a
regular basis by an independent Loan Review Department which reports to the
Company's Board of Directors and 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 with independent information on loan portfolio condition.
 
     Installment and credit card 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.
 
     All past due loans, nonaccrual loans, and troubled debt restructurings are
reviewed at least quarterly by Loan Review Department management and Senior
Credit Committee whose membership includes the Chief Executive Officer of the
Company and the most senior lending officers in the major lending and
credit-related divisions. Loans are placed on nonaccrual when there is doubt as
to the collectibility of interest or principal or if loans are 90 days or more
past due unless they are both well secured and in the process of collection. In
every case, a loan reaching 180 days past due is placed on nonaccrual.
 
     Greater levels of Board and Management attention are being focused on asset
quality. In 1992 an Asset Quality Committee of the Company's Board of Directors
was established which monitors asset quality trends, reviews the loan loss
reserve analyses monthly and actively monitors the large credit exposures. In
1994 this committee began reporting to the Audit Committee. Also in 1992 a new
loan administration function, the Credit Risk Control Department, was assigned
the responsibility of ensuring compliance with the lending policies, procedures
and administrative guidelines of the commercial lending portfolio. The
Department head reports to the Chief Executive Officer. An appraisal review
function was established within the group to review third-party appraisals for
adherence to Federal requirements and to establish policies relating to
collateral appraisal.
 
     In a further step to increase the level of control over the troubled loan
portfolio and in order to focus specialized expertise, a Workout Department was
established during 1992. Most nonaccrual and other troubled loans are handled by
this group or in the Commercial Real Estate Department which is under the
 
                                       22
<PAGE>   25
 
direction of the Workout Department management thereby allowing Commercial Loan
officers to concentrate their efforts on developing new lending relationships.
 
     In 1993 staffing was increased in both the Loan Review and the Credit Risk
Control Departments. Furthermore, a number of systems changes were implemented
in 1993 and 1994 to improve control over credit administration. Smaller
commercial loans were transferred to the Installment Lending Department where
they can be more efficiently monitored.
 
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 on a monthly basis. Factors in this analysis
include historical loss experience and asset quality, as reflected by
delinquency trends, nonaccrual and restructured loans and the Company's credit
risk rating profile. The Company's credit risk rating profile uses categories of
risk based on those currently utilized by its primary regulators. Accuracy of
assigned ratings is monitored by an ongoing evaluation by the Company's Loan
Review Department. Consideration is also given to the current and expected
economic conditions and in particular how such conditions affect the types of
credits in the portfolio and the market area in general. This analysis is
documented monthly using a combination of numerical, statistical and qualitative
analysis (including sensitivity tests) and a written conclusion discussing the
rationale supporting the monthly adequacy of the loan loss reserve.
 
     No portion of the reserve is restricted to any loan or group of loans, and
the entire reserve is available to absorb future realized losses. Realized
losses and the timing thereof may vary from current estimates. An allocation of
the loan loss reserve and ratio of loans in each category to total loans at
December 31, 1990 through 1994 is presented below:

                             RESULTS OF OPERATIONS
 
COMPARISON OF 1994 WITH 1993
 
     For the year ended December 31, 1994, net income was $4.75 million, or
$0.27 per share, compared with a net loss of $20.1 million, or $1.31 per share
in 1993. A key factor behind 1994's positive results was a provision for
possible loan loss of $23.1 million compared with $64.3 million in 1993. In
addition, 1994 writedowns of other real estate owned were $3.8 million compared
with $16.2 million in 1993, a decrease of $12.4 million.
 
     The Company's net interest income on a fully taxable equivalent basis
decreased slightly from $93.9 million in 1993 to $93.1 million. The decrease
reflects a lower volume of interest-earning assets offset by
 
                                       24

an improvement in interest rate spread and margin. Spread and margin benefited
from interest rate increases throughout the year. See "Net Interest Income
Analysis" below.

Net Interest Income Analysis
 
     After a decline in yield on earning assets, principally loans, in the
fourth quarter of 1993 and early 1994, yields, driven by higher interest rates,
rose considerably throughout the remainder of the year. The result was an
improvement in yield on earning assets from 7.51 percent in 1993 to 7.58 percent
in 1994. The cost of interest-bearing liabilities, principally deposits,
remained relatively stable during 1994 until the fourth quarter when the Company
adopted more aggressive deposit pricing. The cost of interest-bearing
liabilities for the year was 2.94 percent compared with 3.13 percent in 1993.
The increased yield on earning assets, which outpaced increases in the cost of
interest-bearing liabilities, produced an improvement in interest rate spread
and margin from 4.38 percent and 4.97 percent in 1993 to 4.64 percent and 5.29
percent, respectively, in 1994. The net effect from changes in rates was an
increase in net interest income of $5.4 million.
 
     Current spreads and margins are at historically high levels and are not
expected to continue into the future. Rates on loans and other interest-earning
assets may continue to increase; however, rates on deposits are expected to rise
at a persistent pace, and narrow the current levels of spread and margin.
 
                                       25
<PAGE>   28
 
     Average loans outstanding during the year were $1.27 billion, a decrease of
$148 million from 1993. Average interest-bearing deposits were $1.18 billion,
$111 million below the 1993 level. The effect from changes in volume of loans,
deposits and other interest-bearing balances was a decrease in net interest
income of $6.2 million.
 
     The following table attributes changes in interest income and interest
expense to changes in interest rates and changes in the volume of
interest-earning assets and interest-bearing liabilities for the year ended
December 31, 1994 when compared with the year ended December 31, 1993. Changes
attributable to both rate and volume are allocated on a weighted basis.

* Fully taxable equivalent at the Federal income tax rate of 34% and includes
  applicable State taxes net of Federal benefit. The tax equivalent adjustment
  on loans was approximately $.8 million and on non-taxable securities was
  approximately $.2 million.

</TABLE>
 
Noninterest Income
 
     Total noninterest income was $30.3 million in 1994, a decrease of $6.4
million from 1993. Gains from the sale of securities decreased $3.3 million,
Asset Management fees decreased $1.4 million and service charges on deposit
accounts decreased $.5 million due to decline in fee-based deposit accounts as
well as higher average individual customer account balances which reduced the
amount of fees assessed. Residual income on maturing equipment leases decreased
$.8 million.
 
     Other noninterest income of $1.4 million declined $.3 million from 1993.
Income recognized in connection with home equity loans purchased from the
Resolution Trust Corporation decreased $.4 million. These loans were originally
purchased at a substantial discount in 1991 and have returned principal on a
schedule closer to the original contractual amount. These decreases to other
noninterest income were partially offset by fees derived from sales of mutual
funds, a new product introduced in May 1994.
 
Noninterest Expense
 
     Total noninterest expense decreased $5 million to $92.5 million in 1994.
Foreclosed asset and workout expense declined $13.4 million as a result of lower
writedowns of other real estate owned. Salary and employee benefits increased
$4.2 million over 1993. In 1994 salary and employee benefits includes expenses
related to severance agreements of $1 million and a $1.2 million asset
management division revenue-sharing provision (see discussion below). The
increase in salary and employee benefits also reflects the addition of a
qualified mutual fund sales staff and increases in professional staff to improve
loan administration and monitoring of
 
                                       26

credit quality. In addition, the rise reflects normal merit raises and employee
benefit cost increases. Occupancy expenses were $.9 million higher reflecting
writedowns of $.5 million in connection with a sale of two former UST/Conn
branch buildings. FDIC deposit insurance premiums declined $.4 million as a
result of a lower level of deposits compared with 1993.
 
     Other noninterest expense increased $3.5 million in 1994, reflecting $1
million in increased legal fees, $1 million in advertising and promotion, $.4
million in collateral appraisal fees and $.9 million in fees for consulting
services by certain former Company executives. The higher other noninterest
expense also stems from a $.8 million reduction in the Company's reserve for
litigation recorded in 1993. The increases were partially offset by a reduction
in property and casualty insurance of $.4 million.
 
     In 1994, the Company and senior executives of USTC's Asset Management
Division negotiated the terms of employment agreements designed to maximize the
profitability and grow the assets under management of the asset management
business. The agreements, which remain subject to regulatory approval, are
designed to increase the foregoing executives' participation in the value
created in the asset management business and, in a change-in-control situation,
increase the likelihood that a prospective purchaser will retain the services of
the executives. The agreements contain revenue-sharing provisions which will
permit the asset management division to use a specified percentage of its base
revenues for the payment of expenses of the operation, including incentive
compensation. In connection therewith, the Company recorded in 1994 a
revenue-sharing provision of $1.2 million.
 
Income Taxes
 
     The Company recorded income taxes of $2.1 million in 1994 compared with a
$11.5 million tax benefit in 1993. The variations in income taxes are
attributable to the level and composition of pretax income or loss. Refer to
Note 11 to the Notes to Consolidated Financial Statements of this Form 10-K for
a further discussion of income taxes.
 
     In 1993 the Company adopted Financial Accounting Standard No. 109
"Accounting for Income Taxes." This Standard changed the accounting for deferred
income tax to the "liability method." This change, a one-time event, increased
net income by $750 thousand in January 1993 representing the cumulative effect
of adopting the new standard on the balance sheet. Refer to Note 1 to the Notes
to Consolidated Financial Statements of this Form 10-K for a further discussion
of this matter.
 
     As of December 31, 1994, the Company had a deferred tax asset of
approximately $11.7 million, net of a valuation allowance of $6.4 million,
included in other assets which is 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
 
     In December 1991, the FASB approved SFAS No. 107, "Disclosures about Fair
Value of Financial Instruments," effective for fiscal year ending December 31,
1992. The methods and assumptions used by the Company to estimate the fair value
of each class of financial instruments as of December 31, 1994 and 1993 are
disclosed in Note 17 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 and liabilities of the Company as of
December 31, 1994 was $1.70 billion and $1.66 billion, respectively. The
estimated fair value of Financial Instrument assets and liabilities of the
Company as of December 31, 1993 was $1.92 billion and $1.89 billion,
respectively. The excess of fair value over the carrying value of Financial
Instrument assets increased slightly from a year ago. In the opinion of
management, the effect of higher interest rates on certain fair value
calculations at December 31, 1994, was more than offset by the positive effect
of lower substandard loans and resulting reduction in credit risk. The decreased
amount of excess in the valuation of Financial Instrument liabilities over their
carrying values, in the opinion of management, is attributed primarily to the
increase in interest rates. Refer to Note 17 to the Notes to Consolidated
Financial Statements of this Form 10-K for a further discussion.

COMPARISON OF 1993 WITH 1992
 
  Net Interest Income Analysis
 
     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-earning liabilities for the year ended
December 31, 1993 when compared with the year ended December 31, 1992. Changes
attributable to both rate and volume are allocated on a weighted basis.

* Fully taxable equivalent at the federal income tax rate of 34% and includes
  applicable State taxes net of federal benefit. The tax equivalent adjustment
  on loans was approximately $.9 million and on non-taxable securities was
  approximately $.2 million.
</TABLE>
 
  Noninterest Income
 
     Total noninterest income of $36.7 million declined $5.6 million in 1993.
Gains on sale of securities decreased $9.3 million. Asset management fees rose
by $3.3 million due to new business and appreciation of existing clients' asset
portfolios, partly offsetting the decrease in securities gains noted above.
Corporate services income increased $1 million, or 13%, in 1993 due to changes
in the fee system and continued expansion of the product base.
 
     Other noninterest income decreased $.5 million in 1993 and the following
are the more significant reasons: Leasing fee income declined $.3 million as the
Company continued to minimize its activity in this area until taxable income
increases sufficiently. Real estate appraisal fees decreased $.2 million due to
a curtailment of third-party activities. Home equity loans purchased from the
Resolution Trust Corporation at a substantial discount in late 1991 returned
principal on a schedule closer to the original contractual amount. This
accounted for an increase of $.4 million compared with 1992 and partially offset
the decreases noted above. Additionally, in the first quarter of 1992, the
Company sold $5.7 million of its credit card portfolio to an unaffiliated bank.
This transaction produced a gain of $.2 million for the quarter ended March 31,
1992. All other miscellaneous noninterest income declined $.2 million.
 
Noninterest Expense
 
     Noninterest expense of $97.5 million remained essentially unchanged in 1993
compared with 1992. Increases in foreclosed asset and workout expense amounted
to $3.1 million. Increases in writedowns of foreclosed real estate properties
totaled $1.7 million while other foreclosed asset and workout expenses increased
$1.4 million. Other noninterest income decreased $5.9 million in 1993. In 1992,
the Company added $3.8 million to a reserve for losses arising from securitized
loans. These losses resulted from an unexpectedly high delinquency and default
rate on securitized automobile loans, which, when recalculating the gain or loss
on the transactions during the Company's regular and systematic review,
necessitated the charge to earnings. There was no comparable expense for 1993 as
there were no loans securitized. The remaining decrease in other noninterest
expense was principally due to a reduction in the Company's provision for
litigation in 1993 as compared with 1992.

(1) For the purpose of this analysis, in 1994 and 1993, securities include
    securities available-for-sale and securities held-to-maturity. For 1992,
    securities include the investment portfolio and securities held for sale.
 
(2) Interest on loans to and obligations of public entities is not subject to
    federal income tax. In order to make pretax yields comparable to taxable
    loans and investments, a tax equivalent adjustment is utilized. The
    adjustment is based on a 34% federal income tax rate and includes applicable
    state taxes net of Federal tax benefit.
 
(3) For the purpose of this analysis, nonaccrual loans are included in the loan
    category.
 
(4) Net interest spread is the excess of the interest rate on average earning
    assets over the interest rate on average interest-bearing liabilities.
 
(5) Net interest margin is the excess of the interest earned over interest
    expense divided by average earning assets.

                    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.
(a Massachusetts corporation) and Subsidiaries as of December 31, 1994 and 1993,
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, 1994. 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 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 are
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
provide a reasonable basis for our opinion.
 
     In our opinion, 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, 1994 and 1993, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1994, in conformity with generally accepted accounting principles.
 
     As explained in Note 1 to the consolidated financial statements, the
Company changed its method of accounting for income taxes and investments by
adopting Statement of Financial Accounting Standards No. 109, "Accounting for
Income Taxes" and Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," effective
January 1, 1993 and December 31, 1993, respectively.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1994
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies of UST Corp. (the "Company") conform
with generally accepted accounting principles and general practice in the
banking industry. The significant policies are summarized below.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All material intercompany balances and
transactions have been eliminated. The parent company only financial statements
contained in Note 16 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. Assets owned by others and held in a
fiduciary or agency capacity are not included in the consolidated balance
sheets.
 
SECURITIES
 
     On December 31, 1993 the Company adopted 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.
 
     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, 1994 and 1993, the Company had no securities classified 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 after-tax gains and losses reported as a
separate component of stockholders' investment. At December 31, 1994,
stockholders' investment was reduced by an unrealized loss related to SFAS No.
115 of $29,023,000 net of an income tax benefit of $5,422,000.
 
     Securities that do not have readily determinable market values are carried
at cost and classified in other assets. At December 31, 1994 and 1993 such
securities amounted to $3,908,000 and $5,071,000, respectively.
 
     Prior to December 31, 1993, debt securities were designated at the time
they were purchased as either held for sale or held to maturity, based on
management intent at the time. Securities which management had the ability and
intent to hold on a long-term basis or until maturity were classified as held to
maturity. Securities which were to be held for indefinite periods of time and
not intended to be held to maturity or on a long-term basis were classified as
securities held for sale and carried at the lower of aggregate cost or market
value.
 
     For mortgage-backed securities, the Company recalculates the effective
yield on the investment to reflect the actual prepayment results and anticipated
future payments. 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 charged or
credited to interest income in the current period.
 
     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 incurring the gain.
 
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
            Furniture and equipment.................................    3-10 years
</TABLE>
 
     Leasehold improvements are amortized over the life of the lease agreements.
 
LOAN INCOME AND FEES
 
     Certain installment loans and commercial time 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 are placed on nonaccrual, with the reversal of all accrued interest
receivable, when there is doubt as to the collectibility of interest or
principal or if loans are 90 days or more past due unless they are both well
secured and in the process of collection. In every case, a loan reaching 180
days past due is placed on nonaccrual. Interest received on nonaccrual loans is
applied to principal if collection of principal is doubtful; otherwise, it is
reflected in interest income on a cash basis.
 
     The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 114 (SFAS No. 114), "Accounting by Creditors for
Impairment of a Loan," as amended by SFAS No. 118. SFAS No. 114 requires that
impaired loans, as defined, be measured based on the present value of the
expected future cash flows discounted at the loan's effective interest rate, or
the fair value of the collateral if the loan is collateral dependent. This
Statement is effective for fiscal years beginning after December 15, 1994.
Management believes that adoption of this Statement will not have a material
effect on the financial condition or results of operations of the Company.
 
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, leases and
commitments to extend credit. Adequacy of the reserve is determined by
management using a consistent methodology which analyzes the size and risk of
the loan portfolio on a monthly basis. Factors in this analysis include past
loan loss experience and asset quality, as reflected by trends of delinquent,
nonaccrual and restructured loans and the Company's credit risk rating profile.
Consideration is also given to the current and expected economic conditions and,
in particular, how such conditions affect the types of credits in the portfolio
and the market area in general. This analysis is documented using a combination
of numerical, statistical and qualitative analysis (including sensitivity
tests), and a written conclusion discussing the rationale supporting reserve
adequacy. 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.

OTHER REAL ESTATE OWNED
 
     Other real estate owned includes both actual and in-substance
repossessions. In December 1992 the Company adopted Statement of Position No.
92-3 ("SOP 92-3") issued by the American Institute of Certified Public
Accountants. This SOP states that foreclosed assets are presumed to be held for
sale. Therefore, they should be carried at the lower of cost or fair value,
minus estimated costs to sell ("net realizable value"). In 1992 the pretax
charge to income resulting from implementation was $750,000.
 
INCOME TAXES
 
     The Company provides for income taxes in accordance with the comprehensive
income tax allocation method. This method recognizes the tax effects of all
income and expense transactions in each year's statement of income regardless of
the year in which the transactions are reported for tax purposes.
 
     The Company follows the deferral method of accounting for investment tax
credits. Under the deferral method, the credit is reflected as a reduction of
tax expense ratably over the period during which the asset is depreciated for
financial reporting purposes.
 
     FASB has issued SFAS No. 109 "Accounting for Income Taxes," a modification
of SFAS No. 96, effective January 1, 1993. While the FASB retained the existing
requirement to record deferred taxes for transactions that are reported in
different years for financial reporting and tax purposes, it revised the
computation of deferred taxes so that the amount of deferred taxes on the
balance sheet is adjusted whenever tax rates or other provisions of the income
tax law are changed. This is known as the "liability method" of providing
deferred income taxes. This change in accounting principle increased net income
$750,000 in January 1993, representing the cumulative effect of the new standard
on the balance sheet at the date of adoption.
 
EARNINGS (LOSS) PER SHARE
 
     Earnings per share is computed using the weighted average number of shares
of common stock and common stock equivalents outstanding. Common stock
equivalents consist primarily of dilutive outstanding stock options computed
under the treasury stock method. Average dilutive common stock equivalents were
379,059 for 1994. Loss per share computations for 1993 and 1992 do not include
common stock equivalents due to their antidilutive effect. The dual presentation
of primary and fully diluted earnings per share is not presented since the
difference from earnings per share is less than 3 percent.
 
GOODWILL AND CORE DEPOSIT INTANGIBLES
 
     Goodwill and core deposit intangibles are stated at cost less accumulated
amortization. Cost of purchased businesses in excess of net assets acquired
("goodwill") includes amounts being amortized over twenty- and forty-year
periods. Amortization expense was $122,500 in each of 1994, 1993 and 1992.
Values assigned to deposits of purchased businesses ("core deposit intangibles")
are being amortized over seven- and thirteen-year periods. Amortization expense
was $1,245,000 in each of 1994, 1993 and 1992.
 
     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.
 
RETIREMENT BENEFITS
 
     In December 1990, the FASB issued SFAS No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions." SFAS No. 106 is effective for
fiscal years beginning after December 15, 1992. This statement did not have any
impact on the Company's financial position or results of operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     In November 1992, the FASB issued SFAS No. 112, "Employers' Accounting for
Postemployment Benefits." SFAS No. 112 is effective for fiscal years beginning
after December 15, 1993. This statement did not have any impact on the Company's
financial position or results of operations.
 
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.
 
(2) RESTRICTIONS ON CASH AND DUE FROM BANKS
 
     At December 31, 1994 and 1993, cash and due from banks included $34,173,000
and $42,072,000, respectively, to satisfy the reserve requirements of the
Federal Reserve Board.
 
(3) SECURITIES
 
     A comparison of the amortized cost, estimated fair value and gross
unrealized gains and losses as of December 31, 1994 and December 31, 1993 for
securities available-for-sale and held-to-maturity follows:

     The amortized cost and estimated market value of debt securities at
December 31, 1994 and 1993, 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 prepayment 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.

     The Company has a qualified Profit-Sharing Plan covering substantially all
employees. Under the plan, up to six percent of net income before income taxes,
as defined, may be contributed to the profit-sharing trust. The Company did not
make a contribution to the profit-sharing trust in 1994, 1993 or 1992.
 
     In January 1994, the Company added an Employee's Savings feature to the
existing Profit Sharing Plan that qualifies as a deferred salary arrangement
under Section 401(k) of the Internal Revenue Code. The new plan was named the
UST Corp. Employee Savings Plan. Under the Savings feature, participating
employees may defer a portion up to 8% of their pretax earnings not to exceed
the Internal Revenue Service annual contribution limits. The Company matches 25%
of each eligible employee's contributions up to 4% of the employee's earnings.
The Company made a matching contribution of $198,000 in 1994, the first year of
the new feature.
 
     The Company also has an ESOP for substantially all employees. Under the
plan, the Company contributes either a fixed amount or a percentage of
compensation of all participants.

nonqualified stock options and shares of restricted stock. At December 31, 1994,
8,479 shares of the Company's common stock remained available for future grants

outstanding on the first day of each fiscal year. As a result, as of January 1,
1995, 220,185 additional common shares were reserved for future grants.

(1) The Company recorded a cumulative $5.4 million tax benefit net of a $6
     million valuation allowance, related to the unrealized loss on securities
     available-for-sale under SFAS No. 115. The Company recognized the
     unrealized loss as a current deduction for income tax purposes which
     contributed to the increase in net operating losses for 1994. In light of
     the size of the unrealized loss and its current level of taxable income,
     the Company concluded that full recognition of the deferred tax amount was
     not appropriate and as such limited the amount of the recorded benefit to
     $5.4 million at December 31, 1994.

(12) CAPITAL AND REGULATORY AGREEMENTS
 
     On June 2, 1993 the Company sold 500,000 shares of its unregistered common
stock in a private placement for a cash price of $3,750,000. Substantially all
of the net proceeds of that placement were used to repay principal on the
Company's long-term debt. On August 12, 1993, the Company sold 2.87 million
shares of its common stock in a European offering. These shares were placed with
more than sixty institutional investors and the offering was made under
Regulation S of the United States Securities and Exchange Commission. Net
proceeds of this placement were approximately $21 million.
 
     The Company and its banking subsidiaries' ability to pay dividends is
subject to certain limitations imposed by statutes of the Commonwealth of
Massachusetts and the State of Connecticut, 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. In the case of
Connecticut law, the limit is undivided profits plus reserve for possible loan
losses. In any event, it is not likely that bank and bank holding company
regulators would allow an institution to dividend any amounts which would reduce
that institution's capital to below the minimum capital requirement in effect at
that time.
 
     In 1992 the Company and its two Massachusetts-based banking subsidiaries,
United States Trust Company ("USTC") and USTrust, signed written agreements with
the Federal Reserve Bank of Boston ("FRB-Boston"), Federal Deposit Insurance
Corporation ("FDIC") and the Banking Commissioner of the Commonwealth of
Massachusetts ("Massachusetts Commissioner"). In accordance with the agreements
the Company agreed not to pay any dividends to stockholders, nor take any
dividends from its banking subsidiaries, without prior regulatory approval.
Similarly, the banking subsidiaries agreed to refrain from transferring funds in
the form of dividends to the Company without prior regulatory approval. In 1994,
the Company received a total of $3 million in dividends from USTC. During the
same period $4.9 million was contributed to UST/Conn and $500 thousand was
contributed to USTrust by the Company to supplement their respective equity
capital accounts.
 
     The banks also agreed to, among other matters, maintain a Tier 1 leverage
capital ratio at or in excess of 6% beginning in February 1993. Tier 1 leverage
capital ratio is defined by the Company's federal regulators to be essentially
stockholders' investment, less intangible assets, divided by total average
assets, less intangible assets. Based on average total assets at December 31,
1994, the Tier 1 leverage capital ratio was 39.46% for USTC and 7.55% for
USTrust. In February 1994, the FDIC and the Massachusetts Commissioner
terminated and lifted the Consent Agreement and Order with USTC. Despite the
termination of its Regulatory Agreement, USTC has agreed to continue to request
regulatory consent prior to the payment of dividends.
 
     Since June 1991, UST/Conn has been operating under a Stipulation and
Agreement with the Banking Commissioner of the State of Connecticut. This
agreement was amended in August 1992, November 1993

and July 1994 and requires, among other things, that UST/Conn maintain a Tier 1
leverage capital ratio of 6%. At December 31, 1994 UST/Conn Tier 1 leverage
capital ratio was 6.40%.
 
     Additionally, the Company agreed to maintain Tier 1, Total risk-based and
Tier 1 leverage capital ratios which conform to the Capital Adequacy Guidelines
of the Board of Governors of the Federal Reserve System. At December 31, 1994,
the Company's Tier 1, Total risk-based capital and Tier 1 leverage ratios were
9.82%, 11.45% and 8.27%, respectively. The Company believes its consolidated
ratios meet the required minimums.
 
(13) 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, 1994, none of these transactions
were on nonaccrual status, nor did they involve delinquent or restructured
loans. However, at December 31, 1994 loans to directors of the Company or to
their affiliated companies in the amount of approximately $14 million (all to
Director Francis X. Messina and his related interests) were characterized as
Substandard, in the Company's internal risk rating profile. Under the Company's
definition, Substandard assets are characterized by the distinct possibility
that some loss will be sustained if the credit deficiencies are not corrected.
However, the Substandard classification does not imply ultimate loss for each
individual asset so classified.
 
     An analysis of loans outstanding in excess of $60,000 to directors and
officers related to the foregoing entities at December 31, 1994 is as follows:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     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 be
likely to result in a material adverse change in the financial condition or
results of operations of the Company and its subsidiaries.
 
(15) 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. 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
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.

</TABLE>
 
     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 may require payment of a fee. Since many of the commitments are
expected to expire without being fully drawn upon and, in fact, have a maturity
of less than one year, 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 $71 million and $31 million were secured by real estate at
December 31, 1994 and December 31, 1993, 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, accounts receivables,
inventory, property plant and equipment. The extent of collateral held for those
commitments

varies from zero to one hundred percent. Of the total standby and commercial
letters of credit, approximately $15 million and $4 million were secured by real
estate at December 31, 1994 and 1993, respectively.
 
     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. Over 90% of the Company's outstanding
commercial and real estate loans are collateralized.
 
     The Company enters into offsetting agreements to purchase foreign currency
and, in turn, sells it to its customers. These contracts carry credit risk
because, in the event the customer fails to take delivery of the foreign
currency, the Company is required to resell it to the open market.
 
     The Company's securities portfolio consists largely of 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. See Note (1), Securities Policies.
 
     In October 1994, the Financial Standards Board issued Statement of
Financial Accounting Standards No. 119 (SFAS No. 119), "Disclosure about
Derivative Financial Instruments and Fair Value of Financial Instruments," which
is effective for fiscal years ending after December 15, 1994. SFAS No. 119
requires certain disclosures about derivative financial instruments including
futures, forward swap and option contracts and other financial instruments with
similar characteristics. As of December 31, 1994, the Company had no investments
requiring disclosure under SFAS No. 119.

     Cash dividends paid to the Company in 1994 by consolidated bank
subsidiaries totaled $3,000,000 and $5,250,000 in 1993. There were no cash
dividends paid to the Company in 1992. No cash dividends were paid to the
Company by other subsidiaries in these years.
 
(17) FINANCIAL INSTRUMENTS
 
     In December 1991, the FASB issued SFAS No. 107, "Disclosures about Fair
Value of Financial Instruments." SFAS No. 107 requires disclosure of the fair
market value of financial instruments, 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.
 
     Cash and due from banks, excess 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 -- 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 of other borrowings were determined by
discounting the anticipated future cash payments by using the rates currently
available to the Company for debt with similar terms and remaining maturities.
 
     Commitments to extend credit/sell loans -- The great majority of
commitments, standby letters of credit and commercial letters of credit are
short term in nature and therefore have been valued at their carrying amount.
 
     Values not determined -- SFAS No. 107 excludes certain assets from its
disclosure requirements including real estate included in banking premises and
equipment, 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.

</TABLE>
 
     As shown above, the Company has been modestly profitable throughout the
two-year period, except for the second quarter of 1993, due to the high
provision for possible loan losses.
 
     In the second quarter of 1993, management changed its strategy regarding
troubled credit situations. While the change would result in the handling of
these situations in an expeditious manner, it was recognized that the up-front
costs of these workouts would increase. As a result, the reserve for possible
loan losses was increased by $19.8 million during the second quarter. To achieve
the higher reserve level, the Company recorded a $42.7 million provision for
possible loan losses in the second quarter. Included in that amount was a
special provision of $50 million. This special provision was management's
estimate of the additional losses to be incurred from the strategic change
referred to above and a continued sluggish economic climate.
 
     In 1994 the Company continued with its strategy to reduce the level of
problem credits while maintaining its reserve for loan loss position. Net
chargeoffs during each quarter were almost entirely matched by provisions to the
loan loss reserve.
 
     Noninterest income decreased after the first quarter of 1993 due to
decreases in gains on sale of securities and declines in service charges on the
deposit accounts and asset management fees. Noninterest expense reflects the
high level of expenses associated with foreclosed asset and loan workouts,
particularly in the second and fourth quarters of 1993 due to writedowns of
other real estate owned.

limiting, defining, or regulating the powers of the corporation, or of its
directors or stockholders, or of any class of stockholders:  SEE ATTACHED
RIDERS A AND B.

RIDER A:  LIABILITY OF DIRECTORS
A Director of this Corporation shall not be personally liable to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director notwithstanding any provision of law imposing such
liability, provided, however, that this provision of Article 6 shall not
eliminate the liability of a director to the extent such liability is imposed
by applicable law (i) for any breach of the director's duty of loyalty to this
Corporation or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
for any transaction from which the director derived an improper personal
benefit, or (iv) for paying a dividend, approving a stock repurchase or making
loans which are illegal under certain provisions of Massachusetts law, as the
same exists or hereafter may be amended. If Massachusetts law is hereafter
amended to authorize the further limitation of the legal liability of the
directors of this Corporation, the liability of the directors shall then be
deemed to be limited to the fullest extent then permitted by Massachusetts law
as so amended. Any repeal or modification of this provision of Article 6 which
may hereafter be effected by the stockholders of this Corporation shall be
prospective only, and shall not adversely affect any limitation on the
liability of a director for acts or omissions prior to such repeal or
modification.

RIDER B:  INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS
The Corporation shall to the fullest extent legally permissible indemnify each
person who is or was a director, officer, employee or other agent of the
Corporation and each person who is or was serving at the request of the
Corporation as a director, trustee, officer, employee or other agent of another
corporation or of any partnership, join venture, trust, employee benefit plan
or other enterprise or organization against all liabilities, costs and
expenses, including but not limited to amounts paid in satisfaction of
judgments, in settlement or as fines and penalties, and counsel fees and
disbursements, reasonably incurred by him in connection with the defense or
disposition of or otherwise in connection with or resulting from any action,
suit or other proceeding, whether civil, criminal, administrative or
investigative, before any court or administrative or legislative or
investigative body, in which he may be or may have been involved as a party or
otherwise or with which he may be or may have been threatened, while in office
or thereafter, by reason of his being or having been such a director, officer,
employee, 
<PAGE>   3
agent or trustee, or by reason of any action taken or not taken in any such 
capacity, except with respect to any matter as to which he shall have been 
finally adjudicated by a court of competent jurisdiction not to have acted
in good faith in the reasonable belief that his action was in the best
interests of the Corporation (any person serving another organization in one or
more of the indicated capacities at the request of the Corporation who shall
not 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 such other
organization shall be deemed so to have acted in good faith with respect to the
Corporation) or to the extent that such matter relates to service with respect
to an employee benefit plan, in the best interest of the participants or
beneficiaries of such employee benefit plan. Expenses, including but not
limited to counsel fees and disbursements, so incurred by any such person in
defending any such action, suit or proceeding, shall be paid from time to time
by the Corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the person
indemnified to repay the amounts so paid if it shall ultimately be determined
that indemnification of such expenses is not authorized hereunder.

If, in an action, suit or proceeding brought by or in the name of the
Corporation, a director of the Corporation is held not liable for monetary
damages, whether because that director is relieved of personal liability under
the provisions of this Article 6 of the Articles of Organization, or otherwise,
that director shall be deemed to have met the standard of conduct set forth
above and to be entitled to indemnification for expenses reasonably incurred in
the defense of such action, suit or proceeding.

As to any matter disposed of by settlement by any such person, pursuant to a
consent decree or otherwise, no such indemnification either for the amount of
such settlement or for any other expenses shall be provided unless such
settlement shall be approved as in the best interests of the Corporation, after
notice that it involves such indemnification, (a) by vote of a majority of the
disinterested directors then in office (even though the disinterested directors
be less than a quorum), or (b) by any disinterested person or persons to whom
the question may be referred by vote of a majority of such disinterested
directors, or (c) by vote of the holders of a majority of the outstanding stock
at the time entitled to vote for directors, voting as a single class, exclusive
of any stock owned by any interested person, or (d) by any disinterested person
or persons to whom the question may be referred by vote of the holders of a
majority of such stock. No such approval shall prevent the recovery from any
such officer, director, employee, agent or trustee of any amounts paid to him
or on his behalf as indemnification in accordance with the preceding sentence
if such person is subsequently adjudicated by a court of competent jurisdiction
not to have acted in good faith in the reasonable belief that his action was in
the best interests of the Corporation.

The right of indemnification hereby provided shall not be exclusive of or
affect any other rights to which any director, officer, employee, agent or
trustee may be entitled or which may lawfully be granted to him. As used
herein, the terms "director", "officer", "employee", "agent", and "trustee"
include their respective executors, administrators and other legal
representatives, an "interested" person is one against whom the action, suit or
other proceeding in question or another action, suit or other proceeding on the
same or similar grounds is then or had been pending or threatened, and a
"disinterested" person is a person against whom no such action, 

<PAGE>   4
suit or other proceeding is then or had been pending or threatened.

By action of the board of directors, notwithstanding any interest of the
directors in such action, the Corporation may purchase and maintain insurance,
in such amounts as the board of directors may from time to time deem
appropriate, on behalf of any person who is or was a director, officer,
employee or other agent of the Corporation, or is or was serving at the request
of the Corporation as director, trustee, officer, employee or other agent of
another corporation or of any partnership, joint venture, trust, employee
benefit plan or other enterprise or organization against any liability incurred
by him in any such capacity, or arising out of his status as such, whether or
not the Corporation would have the power to indemnify him against such
liability."

        *We further certify that the foregoing restated articles of
organization effect no amendments to the articles of organization of the
corporation as heretofore amended, except amendments to the following articles:
None

entitled to vote thereat and to each stockholder, who by law, by the Articles
of Organization or by these By-Laws is entitled to such notice, by leaving such
notice with him or at his residence or usual place of business, or by mailing
it postage prepaid and addressed to such stockholder at his address as it

                 6. VOTING AND PROXIES. Each stockholder shall have one vote

executed by one of them unless at or prior to exercise of the proxy the
corporation receives a specific written notice to the contrary from any one of
them.   A proxy purporting to be executed by or on behalf of a stockholder

larger vote is required by law, the Articles of Organization or these
By-laws, shall decide any matter to be voted on by the stockholders. Any
election by stockholders shall be determined by a plurality of the votes cast
by the stockholders entitled to vote at the election. No ballot shall be
required for such election unless requested by a stockholder present or
represented at the meeting and entitled to vote in the election. The
corporation shall not directly or indirectly vote any share of its stock.

                 8. ACTION WITHOUT MEETING. Any action to be taken by 
stockholders may be taken without a meeting if all stockholders entitled to 
vote on the matter consent to the action by a writing filed with the records 
of the meetings of stockholders. Such consent shall be treated for all 
purposes as a vote at a meeting.

the election of Directors, provided that the Directors of a class elected by
a particular class of stockholders may be removed only by the vote of the
holders of a majority of the shares of such class or (b) for cause by vote of
a majority of the Directors then in office. A Director may be removed for
cause only after reasonable notice and opportunity to be heard before the body
proposing to remove him.

                7. MEETINGS. Regular meetings of the Directors may be held 
without call or notice at such places and at such times the Directors may 
from time to time determine, provided that any Director who is absent when
such determination is made shall be given notice of the determination. A
regular meeting of the Directors may be held without a call or notice at the
same place as the annual meeting of stockholders, or the special meeting held
in lieu thereof, following such meeting of stockholders.
                Special meetings of the Directors may be held at any time and
place designated in a call by the President, Treasurer or two or more
Directors.

Director if a written waiver of notice, executed by him before or after the
meeting, is filed with the records of the meeting, or to any Director who
attends the meeting without protesting prior thereto or at its commencement

which a quorum is present, the vote of a majority of those present, unless a
different vote is specified by law, by the Articles of Organization, or by
these By-Laws, shall be sufficient to decide such matter.

                 11. ACTION BY CONSENT. Any action by the Directors
may be taken without a meeting if a written consent thereto is signed by all
the Directors and filed with the records of the Directors' meetings Such
consent shall be treated as a vote of the Directors for all purposes.

                 12. COMMITTEES. The Directors may, by vote of a majority of
the Directors then in office, elect from their number an executive or other
committees and may by like vote delegate thereto some or all of their powers
except those which by law, the Articles of Organization or these By-Laws they
are prohibited from delegating. Except as the Directors may otherwise
determine, any such committee may make rules for the conduct of its business,

                  1. CERTIFICATES OF STOCK. Each stockholder shall be entitled 
to a certificate of the capital stock of the corporation in such form as may 
be prescribed from time to time by the Directors. The certificate shall be 
signed by the President or a Vice President, and by the Treasurer or an 
Assistant Treasurer, but when a certificate is countersigned by a transfer
agent or a registrar, other than a Director, officer or employee of the
corporation, such signatures may be facsimiles. In case any officer who has
signed or whose facsimile signature has been placed on such certificate shall
have ceased to be such officer before such certificate is issued, it may be
issued by the corporation with the same effect as if he were such officer at
the time of its issue.
                  Every certificate for shares of stock which are subject to 
any restriction on transfer pursuant to the Articles of Organization, the 
By-Laws or any agreement to which the corporation is a party, shall have 
                



<PAGE>   7
the restriction noted conspicuously on the certificate and shall also set forth
on the face or back either the full text of the restriction or a statement of
the existence of such restriction and a statement that the corporation will
furnish a copy to the holder of such certificate upon written request and
without charge. Every certificate issued when the corporation is authorized
to issue more than one class or series of stock shall set forth on its face
or back either the full text of the preferences, voting powers, qualifications
and special and relative rights of the shares of each class and series
authorized to be issued or a statement of the existence of such preferences,
powers, qualifications and rights, and a statement that the corporation will
furnish a copy thereof to the holder of such certificate upon written request
and without charge.

                 2. TRANSFERS. Subject to any restrictions on transfer which
may be set forth in this Article IV, shares of stock may be transferred on
the books of the Corporation or by the surrender to the Corporation or its
transfer agent of the certificate therefor properly endorsed or accompanied by 
written assignment and power of attorney properly executed, with necessary 
transfer stamp affixed, and with such proof of the authenticity of signature 
as the Corporation or its transfer agent may reasonably require. Except as may
be otherwise required by law, by the Articles of Organization or by these 
By-Laws, the Corporation shall be entitled to treat the record holder of stock 
as shown on its books as the owner of such stock for all purposes, including 
the payment of dividends and the right to vote with respect thereto, regardless 
of any transfer, pledge or other disposition of such stock, until the shares 
have been transferred on the books of the Corporation in accordance with the 
requirements of these By-Laws.
                 It shall be the duty of each stockholder to notify the 
Corporation of his post office address.

                 3. RECORD DATE. The Directors may fix in advance a
time of not more than sixty days preceding the date of any meeting of
stockholders, or the date for the payment of any dividend or the making of
any distribution to stockholders, or the last day on which the consent or
dissent of stockholders may be effectively expressed for any purpose, as the
record date for determining the stockholders having the right to notice of
and to vote at such meeting, and any adjournment thereof, or the right to
receive such dividend or distribution or the right to give such consent or
dissent.   In such case only stockholders of record on such record date shall
have such right, notwithstanding any transfer of stock on the books of the
corporation, after the record date. Without fixing such record date, the
Directors may for any of such purposes close the transfer books for all or
any part of such period.

                 4. REPLACEMENT OF CERTIFICATES. In case of the alleged loss 
or destruction or the mutilation of a certificate of stock, a duplicate   
certificate may be issued in place thereof, upon such terms as the Directors 
may prescribe.

stock held by each, shall be kept in Massachusetts at the principal office of 
the corporation, or at an office of its transfer agent or of the Clerk. Said 
copies and records need not all be kept in the same office. They shall be 
available at all reasonable times to the inspection of any stockholder for any 
proper purpose but not to secure a list of stockholders for the purpose of

               follows:

               "(f)   Restriction on Payment Options.  An election of an
                      optional form of payment under Section 10.3 shall not be
                      effective unless the benefit payable under the form of
                      payment elected satisfies the requirements of Proposed
                      Income Tax Regulation 1.401(a)(9)-2 or other applicable
                      law."

               (iv)   The right to revoke and the effect of revocation of the

                      applicable regulations.

               The notice described above is not required if the Actuarial
               Equivalent value of the Participant's nonforfeitable Accrued
               Benefit is less than or equal to $3,500 on the date the
               Participant's benefit commences.

<PAGE>   3
               not exceed $3,500 on the date the Participant's benefit 
               commences, the notice furnished by the Benefits Committee shall 
               include an explanation of:  (1) the rules under which a 
               distribution may be made in a direct rollover to an eligible 
               retirement plan; (2) the tax withholding rules for direct 
               rollovers and for the 60-day rollover option; and (3) the 
               requirements for favorable tax treatment in accordance with 
               applicable law."

         9.    Section 10.9 shall be amended by adding the following paragraph
               to the end thereof:

               "Notwithstanding any provision of the Plan to the contrary, all
               distributions under the Plan shall comply with the requirements
               of Section 401(a)(9) of the Code."

        10.    A new Section 10.12 shall be added effective January 1, 1993 to
               read as follows:

               "This Section 10.12 shall apply only to distributions made
               pursuant to Section 10.6.

               Notwithstanding any provision of the Plan to the contrary, if
               any distribution to a Participant, surviving Spouse or Alternate
               Payee (i) is made on or after January 1, 1993, (ii) totals $200
               or more, and (iii) constitutes an "eligible rollover
               distribution" (within the meaning of Section 402(c)(4) of the
               Code), the individual 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 individual.  For this purpose,
               an "eligible retirement Plan" means:

               (a)    an individual retirement account described in Section
                      408(a) of the Code;

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

               (c)    with respect to Participants and 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

               (d)    with respect to Participants and 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 rollover must total $500 or more.

               If the Participant, Participant's surviving Spouse or Alternate
               Payee does not make






                                                                               3

               a timely election whether or not to directly roll over the
               distribution, such distribution shall be made directly to the
               applicable individual.

               Direct rollovers shall be accomplished in accordance with
               procedures established by the Benefits Committee."

        11.    Section 12.1(b) shall be amended effective January 1, 1987 by
               replacing the second sentence with the following:

               "The adjustment required pursuant to the preceding sentence for
               any year shall be the cost of living adjustment that is
               effective as of the January 1 that occurs in such year.  No such
               adjustment shall be taken into account before the year for which
               such adjustment first takes effect."

        12.    Section 12.1(f) shall be amended effective January 1, 1987 by
               deleting the last sentence which reads as follows:

               "This paragraph shall be applied separately with respect to each
               change in benefit structure as defined by Section 415(b)(5)(D)
               of the Code and regulations."

        13.    Section 12.2 shall be amended effective January 1, 1987 by
               adding the following paragraph to the end thereof:

               "If the sum of a Participant's defined benefit plan fraction and
               defined contribution plan fraction determined as of December 31,
               1986 would have exceeded 1.0 had the provisions of this Article
               12 as in effect after December 31, 1986 been used to compute
               such sum, an amount shall be subtracted from the numerator of
               the defined contribution plan fraction (not exceeding such
               numerator) so that the sum of the defined contribution plan
               fraction and defined benefit plan fraction as of the first day
               of the Limitation Year beginning in 1987 does not exceed 1.0.
               Such amount shall be equal to the product of:

               (i)    the sum of the defined contribution plan fraction plus
                      the defined benefit plan fraction as of the determination
                      date minus one, times

               (ii)   the denominator of the defined contribution plan fraction
                      as of the determination date."

        14.    Section 12.4 shall be amended effective January 1, 1994 by
               replacing paragraphs (b) through (e) with the following:

               "(b)   For purposes of this Section 12.4, the following terms
               shall have the





                                                                               4
<PAGE>   5
                      indicated meaning:

                      (i)     "Benefits" means the sum of the Participant's
                              Accrued Benefit and all other benefits to which
                              he is entitled under the Plan, but excluding any
                              death benefit provided for by insurance on the
                              Participant's life.

                      (ii)    "Restricted Participant" means, with respect to a
                              Plan Year, a highly compensated employee who is a
                              Participant and who, if there are more than 25
                              highly compensated employees, is one of the 25
                              highly compensated employees with the highest
                              Total Annual Pay.  An individual who is a
                              Restricted Participant in a Plan Year shall be a
                              Restricted Participant in a subsequent Plan Year
                              only if he satisfies the conditions of the
                              previous sentence in that subsequent Plan Year.
                              If more than one individual has the same Total
                              Annual Pay, the younger individual shall be
                              deemed to have the higher Total Annual Pay.

                      (iii)   "Total Annual Pay" means, with respect to any
                              Plan Year, (A) in the case of a highly
                              compensated employee who is not currently
                              employed by an Employer or an Affiliated
                              Employer, the greater of his compensation (as
                              defined under Section 415 of the Code for the
                              Plan Year he ceased to be employed by an Employer
                              or Affiliated Employer or his earnings for the
                              Plan Year immediately preceding that Plan Year
                              and (B) in the case of a highly compensated
                              employee who is currently employed by an Employer
                              or Affiliated Employer, the greater of his
                              earnings for the Plan Year in question or for the
                              prior Plan Year.

               (c)    Subject to paragraph (d) below, a Restricted Participant
                      may not receive his benefits under this Plan in the form
                      of a single sum payment, or other benefit form under
                      which payments during a single year would exceed the
                      annual payments that would be made on behalf of the
                      Participant under a single life annuity that is the
                      Actuarial Equivalent of his Benefits.

               (d)    The limitation of paragraph (c) above shall not apply to:

                      (i)     payment of benefits attributable to transferred
                              balances from defined contribution plans or to
                              employee contributions,

                      (ii)    any payment, if the value of Plan assets after
                              such payment equals or exceeds 110 percent of the
                              value of the Plan's "current liabilities" (within
                              the meaning of Section 412(1)(7) of the Code),





                                                                               5
<PAGE>   6
                      (iii)   any payment, if the value of the Restricted
                              Participant's Benefits is less than one percent
                              of the value of such "current liabilities," or

                      (iv)    any payment, if the value of the Restricted
                              Participant's Benefits does not exceed $3,500.

               (e)    In the event that Congress provides by statute, or the
                      Internal Revenue Service provides by regulation or
                      ruling, that the limitations set forth in this Section
                      12.4 are not necessary for the Plan to meet the
                      requirements of Section 401(a) or other applicable
                      provisions of the Code then in effect, such limitations
                      shall become void and shall no longer apply without the
                      necessity of further amendment to the Plan."

        15.    A new Section 12.5 shall be added to read as follows:

               "12.5  TRANSITIONAL BENEFIT LIMITATIONS

                      Notwithstanding any other provision of the Plan to the
                      contrary, in calculating the Accrued Benefit (including
                      the right to any optional benefit provided under the
                      Plan) of any Participant, such Participant shall accrue
                      no additional benefit under the Plan on or after the
                      Effective Date to the extent that such additional benefit
                      accrual exceeds the benefit which would otherwise accrue
                      in accordance with the terms of the Plan as amended to
                      comply with the qualification requirements described in
                      IRS Regulations Section 1.401(b)-1(b)(2)(ii)."

         16.   Section 13.4 shall be amended by adding the phrase "and
               discretion" immediately following "The Benefits Committee shall
               have such power."

         17.   Section 14.5 shall be amended by adding the following paragraph
               to the end thereof:

               "The Plan Administrator or the Sponsoring Employer may direct
               the Trustee to pay from the Trust Fund any or all expenses of
               administering the Plan, to the extent such expenses are
               reasonable.  The Plan Administrator or the Sponsoring Employer
               will determine what constitutes a reasonable expense of
               administering the Plan, 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 Plan
               Administrator or the Sponsoring Employer may direct the Trustee
               to reimburse the Sponsoring Employer out of the Trust Fund for a
               reasonable expense of administering the Plan which is paid by

               expense."

         18.   A new Section 16.5 shall be added to read as follows:

               "16.5 APPROVAL BY INTERNAL REVENUE SERVICE: MISTAKE OF FACT

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

                    Each Employer contribution is hereby conditioned on the
                    current 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."

         19.   A new Section 16.6 shall be added to read as follows:

               "16.6 BENEFITS PAYABLE ONLY FROM TRUST FUND

                    All benefits payable under this Plan shall be paid or
                    provided for solely from the Trust Fund, and neither any
                    Employer nor its shareholder, directors, employees, or any
                    member of the Benefits Committee shall have any liability
                    or responsibility therefor.  Except as otherwise provided
                    by law, no Employer assumes any obligations under this Plan
                    except those specifically stated in the Plan."

         20.   Section 17.1 is amended in its entirety to read as follows:

               "17.1  AMENDMENT

                      (a)    The Sponsoring Employer, by written action of its
                             Board (or, to the extent permitted by resolution
                             of such Board, by action of the Benefits Committee
                             or a duly authorized officer of the Sponsoring
                             Employer), shall have the right at any time and
                             from time to time to amend, in whole or in part,
                             any or all of the provisions of this Plan.  No
                             such amendment shall, however:

                               (i)   Authorize or permit any part of the Trust
                                     Fund (other than such part as is required
                                     to pay taxes and administrative expenses)
                                     to be used for or diverted to purposes
                                     other than for the exclusive benefit of
                                     the Participants or their Beneficiaries or
                                     estates prior to the satisfaction of all

                                     estates;

                              (ii)   Cause any reduction in the Accrued Benefit
                                     of any Participant, or the elimination of
                                     any optional forms of benefit payment or
                                     retirement type subsidies (as defined in
                                     applicable regulations) except as
                                     permitted by law;

                             (iii)   Cause or permit any portion of the Trust
                                     Fund to revert to or become the property
                                     of the Employer except to the extent
                                     provided under Sections 17.2 and 16.5; or

                              (iv)   Amend the Plan or Trust in such manner as
                                     would increase the duties or liabilities
                                     of the Trustee or affect his fee for
                                     services hereunder, unless the Trustee
                                     consents thereto in writing;

                             unless such modification or amendment is necessary
                             or appropriate to enable the Plan or Trust Fund to
                             qualify under Section 401(a) of the Code, or to
                             retain for the Plan or Trust Fund its qualified
                             status.

                      (b)    If any Plan amendment changes the vesting schedule
                             set forth in Section 8.1, each Participant who has
                             completed at least three years of Vesting Service
                             on the effective date of the change in vesting
                             schedule shall have his vesting percentage
                             computed in accordance with the vesting schedule
                             which produces the highest vested benefit.

                      (c)    All provisions of this Plan, and all benefits and
                             rights granted hereunder, are subject to any
                             amendments, modifications or alterations which are
                             necessary from time to time to qualify this Plan
                             under Section 401(a) of the Code, to continue the
                             Plan as so qualified or to comply with any other
                             provision of law. Accordingly, notwithstanding any
                             other provision of this Plan, the Sponsoring
                             Employer may amend, modify, or alter this Plan
                             with retroactive effect in any respect or manner
                             necessary to qualify this Plan under Section
                             401(a) of the Code, or to continue this Plan as so
                             qualified or to comply with any other provision of
                             applicable law.

                      (d)    If the effect of any amendment is to increase the
                             current liability (as defined in Section
                             401(a)(29)(E) of the Code) under the Plan for a
                             Plan Year, and the funded current liability
                             percentage of the Plan for the Plan Year in which
                             the amendment would otherwise take effect is less
                             than sixty percent (60%), including the amount of
                             the unfunded current liability under the Plan
                             attributable to the amendment, the amendment





                                                                               8

                         shall not take effect until the Employer or Sponsoring
                         Employer (or any Affiliated Employer) provides 
                         security to the Plan.  The form and amount of the 
                         security shall satisfy the requirements of Section
                         401(a)(29)(B) and (C) of the Code.  The security may 
                         be released provided the requirements of Section 
                         401(a)(29)(D) of the Code are satisfied."
        
         21.   Section 17.2 is hereby amended by inserting the phrase ", by
               written resolution of the Board," immediately following the
               phrase "In the event."

         22.   Section 17.5 is hereby amended by inserting the phrase ", by
               written resolution of the Board," immediately following the
               phrase "In the event."


IN WITNESS WHEREOF, UST Corp. has caused this Amendment to be executed by its
duly authorized officer and its corporate seal to be affixed hereto this 20th
day of December, 1994.

                    UST CORP. EMPLOYEE STOCK OWNERSHIP PLAN

                  (AMENDED AND RESTATED AS OF JANUARY 1, 1989)


                                SECOND AMENDMENT    


         WHEREAS, the UST Corp. Employee Stock Ownership Plan (the "Plan") was
amended and restated effective January 1, 1989; and


         WHEREAS, Section 13.1 gives UST Corp. the authorization to amend the
Plan; and


         WHEREAS, UST Corp. desires to amend the Plan to comply with the
Unemployment Compensation Amendments of 1992 and other subsequent legislation;


         NOW, THEREFORE, UST Corp. hereby amends the Plan in the following
respects:

         1.     Section 1.4, "Alternate Payee," is hereby amended, effective
                January 1, 1993, by adding the following sentence:

                "For purposes of Section 6.15, the term "Alternate Payee"
                excludes a child or other dependent of the Participant."

         2.     Section 1.12, "Compensation", is hereby amended by deleting
                the third paragraph thereof in its entirety and inserting in
                its place the following:

                "In no event shall a Participant's Compensation taken into
                account under the Plan for any Plan Year commencing on or
                after January 1, 1989 exceed $200,000 ($150,000 for Plan Years
                beginning on or after January 1, 1994), or such other amount
                as the Secretary of the Treasury may determine for such Plan
                Year in accordance with Section 401(a)(17) of the Code.  Any
                change in the dollar amounts set forth above as adjusted by
                the Secretary of the Treasury in accordance with Section
                401(a)(17) of the Code shall apply only to Compensation taken
                into account for Plan Years beginning with the Plan Year in
                which such increase is effective.

                In determining the Compensation of a Participant for purposes
                of this dollar limitation, the rules of Section 414(q)(6) of
                the Code shall apply, except that in applying such rules, the
                term 'family' shall include only the Spouse of the Participant
                and any lineal descendants of the Participant who have not
                attained age 19 before the close of such year."

<PAGE>   2
         3.     A new Section, Section 6.15, is added effective January 1,
                1993:

                "6.15   DIRECT ROLLOVER DISTRIBUTIONS

                (a)     Notwithstanding any provision of the Plan to the
                        contrary, if any distribution to a Participant,
                        surviving Spouse or Alternate Payee (i) is made on or
                        after January 1, 1993, (ii) totals $200 or more, and
                        (iii) constitutes an "eligible rollover distribution"
                        (within the meaning of Section 402(c)(4) of the
                        Code), the individual may elect on a form provided by
                        the Committee to have all or part of such eligible
                        rollover distribution paid in a direct rollover to an
                        "eligible retirement plan" (as defined in paragraph
                        (b) below) selected by the individual.

                (b)     The term "eligible retirement plan" means:

                     (i)   an individual retirement account described in
                           Section 408(a) of the Code;

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

                   (iii)   with respect to Participants and Alternate Payees,
                           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 Alternate Payees,
                           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 rollover must
total $500 or more.

Direct rollovers shall be accomplished in accordance with procedures
established by the Committee, including, in the case of distributions not
subject to the consent requirements of Section 411(a)(11) of the Code,
procedures for affirmatively waiving the minimum notice period described in
Income Tax Regulation 1.402(c)-2T.

The procedures established by the Committee shall be made in accordance
with the rules set forth in Income Tax Regulation 1.401(a)(31)-1T."

         4.     Section 13.1, "Amendment," is hereby amended by deleting that
                Section in its entirety and inserting in its place the
                following:

                "The Sponsoring Employer may, by written resolution of its
                Board, amend this instrument, from time to time, by an
                instrument in writing duly executed by the 

<PAGE>   3
                Sponsoring Employer and delivered to the Trustee, provided 
                that no amendment which affects the Trustee shall be effective
                without the Trustee's consent."

        5.      Section 13.3, "Termination," is hereby amended by deleting the
                first sentence of the first paragraph thereof and inserting in
                its place the following:

"Sponsoring Employer may terminate the Plan established hereunder at its 
option at any time by written resolution of its Board."


                IN WITNESS THEREOF, UST Corp. has caused this amendment to be
        executed by its duly authorized officer and its corporate seal to be
        affixed hereto this 20th day of December, 1994.

       as specified in Section 1.1 of this Plan and certain periods of absence

       this Plan, shall be treated as employment with the Employer for vesting
       purposes, but not for purposes of allocations hereunder, unless
       otherwise provided herein.  Service with a predecessor organization of
       the Employer also shall be treated as Service with the Employer if the
       Employer maintains the Plan of such predecessor organization.  In

       credited for periods during which the Employee is on a
       Maternity/Paternity Leave of Absence, as follows.  Hours of Service
       shall be credited for the Plan Year in which the absence from work
       begins, only if credit in such year is necessary to prevent the Employee
       from incurring a One-Year Break in Service, or, in any other case, in
       the immediately following Plan Year.  The Hours of Service credited for
       a Maternity/Paternity Leave of Absence shall be those which would
       normally have been credited but for such absence, or, in any case in
       which the Benefits Committee is unable to determine such hours normally

2.4    EXCLUDED YEARS OF SERVICE

       In determining the vested percentage of an Employee in his Regular
       Profit Sharing Account at any point in time, all Years of Service shall
       be taken into account, except as follows.  Years of Service prior to a
       One-Year Break in Service shall be disregarded if:

              Profit Sharing Contributions at the time the break occurred;  and

       (b)    The number of consecutive One-Year Breaks in Service equals or
              exceeds the greater of:

               (i)   Five;  or

              (ii)   The Participant's Years of Service at the time the break
                     occurred.

       Notwithstanding any of the above, Years of Service prior to a One-Year
       Break in Service will not count for purposes of determining an
       Employee's vesting percentage until the Employee has completed one Year
       of Service following the Employee's reemployment date.

2.5    TRANSFERS

       (a)    If an Employee transfers from employment not covered by this Plan
              (e.g., employment pursuant to a collective bargaining agreement)

              his Service from his first date of employment with the Employer
              shall be considered for purposes of calculating his Service for
              vesting.

       (b)    If an Eligible Employee or Participant transfers to a noncovered
              job classification, (e.g., employment covered by a collective
              bargaining agreement), he shall cease to participate in the
              allocation of contributions and forfeitures hereunder, but he
              shall continue to participate in the Plan for purposes of
              determining the vested interest in his Regular Profit Sharing
              Account pursuant to Article 7.

                                                                            (18)

              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.

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





                                                                            (19)
<PAGE>   28
       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. 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.





                                                                            (20)
<PAGE>   29
              If the Participant fails to notify the Benefits Committee by the
              2-month period specified above, no refund will be made.





                                                                            (21)

                             EMPLOYER CONTRIBUTIONS

5.1    EMPLOYER PROFIT SHARING CONTRIBUTION

       (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.

              For purposes of this Section, "NET PROFITS" means the net income
              of the Employer before payment of any Federal and/or state income
              taxes and/or any other Federal taxes imposed on or measured by
              net income for the taxable year in question, determined in
              accordance with generally accepted accounting principles,
              provided, however, that in computing the Net Profits for any
              taxable year, neither the amount of the contribution to be made
              under this Plan nor the amount of any contribution made by the
              Employer under any other plan qualified under Section 401(a) of
              the Code shall be included among the deductions.

              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





                                                                            (22)
<PAGE>   31
                     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 receive an
                     immediate cash payment of the Cash Option Share under this
                     Section, it shall be assumed that he intended to have his
                     Cash Option Share deferred and credited to his Cash Option
                     Deferred Account.

            (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





                                                                            (23)
<PAGE>   32
              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)    SHARING OF EMPLOYER PROFIT SHARING CONTRIBUTION

              To the extent an Employer is prevented from making a Profit
              Sharing Contribution under this Section 5.1, because such
              Employer has no current or accumulated Net Profits or because
              such profits are less than the contributions it otherwise would
              have made, the following shall occur.  Such prevented
              contribution shall be made by the other Employers out of their
              Net Profits, provided that the contributions of these Employers
              shall be limited, in cases which the Employers do not file a
              consolidated Federal Corporate income tax return, as follows.
              The amount contributed shall equal the proportion of each such
              Employer's Net Profits remaining after adjustment for its
              deductible contribution without regard to Section 404(a)(3)(B) of
              the Code which the total prevented contribution bears to the Net
              Profits of all the Employers remaining after adjustment for all
              deductible contributions without regard to said Code Section.

       (f)    RESPONSIBILITY OF COMMITTEE AND TRUSTEE

              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.

       (g)    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





                                                                            (24)
<PAGE>   33
            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 amount of Employer Matching Contributions made
       on behalf of each such Participant shall be 25% of the Participant's
       Basic Before-Tax Contributions made since the previous Valuation Date.

       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.

5.3    DEDUCTIBILITY OF EMPLOYER CONTRIBUTIONS

       The Employer shall not make any Employer Contributions to the extent
       such Contributions would exceed the maximum amount allowable as a
       deduction under Section 404 of the Code for the Plan Year in question,
       giving effect to the provisions for carryover of unused deductions, if
       any.

5.4    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.





                                                                            (25)

                INVESTMENT PROVISIONS AND PARTICIPANT ACCOUNTS

6.1    INVESTMENT FUNDS

       The Trustee shall establish one or more investment funds as the
       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
              accordance with such investment guidelines and objectives as may
              be established by the Sponsoring Employer; or

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

       Notwithstanding the foregoing, Employer Profit Sharing Contribution made
       in accordance with Section 5.1 shall be invested in the UST Managed
       Growth Retirement Fund.  This Fund contains a balanced investment
       portfolio consisting of stocks, bonds, and other fixed income
       instruments.

       The Sponsoring Employer may from time to time change its direction with
       respect to any investment fund and may, at any time, eliminate any
       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.





                                                                            (26)
<PAGE>   35
       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.

6.2    INVESTMENT ELECTION

       (a)    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 10% or 25%,
              up to a total of 100%.  A Participant's investment elections must
              total 100%.

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

       (c)    Notwithstanding the foregoing, the Regular Profit Sharing Account
              and Cash Option Deferred Account shall be invested solely in the
              UST Managed Growth Retirement Fund.

6.3    CHANGE IN INVESTMENT ELECTION

       A Participant may elect, effective as of any Change Date, to reallocate
       in 10% or 25% increments his Basic and Supplemental Before-Tax
       Contribution Accounts, Employer Matching Contribution Account, and
       Rollover Account among the investment funds, provided that at least 30
       days in advance of such Change Date the Participant files with the
       Benefits Committee a new election on the appropriate form, and further
       provided that any such election shall not apply to the Loan Fund.  Any
       elections made in accordance with this paragraph shall apply to the
       amounts existing in the Participant's Basic 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.





                                                                            (27)
<PAGE>   36
       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;
             (v)     Cash Option Deferred Account; and
            (vi)     Rollover Account.





                                                                            (28)
<PAGE>   37
       (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 and the Loan 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.





                                                                            (29)
<PAGE>   38
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.





                                                                            (30)

                                   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 Total 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.

       If the value of a Participant's vested Account is in excess of $3,500,
       payment to the 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 between the date the Participant attains age 59 1/2 and the April 1
       following the calendar year in which the Participant attains age 70 1/2.

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:





                                                                            (31)

       (a)    Normal Retirement Date,

       (b)    Death (while actively employed), or

       (c)    Disability Retirement Date.

       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:

       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 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.





                                                                            (32)
<PAGE>   41
       (b)    After January 1, 1985:
              ---------------------

                 (i)   Timing of Forfeitures:
                       ---------------------

                       If a Participant terminates his employment with the
                       Employer before his Regular Profit Sharing Account had
                       become 100% vested, the nonvested amount remaining in
                       such Participant's Regular Profit Sharing Account shall
                       be forfeited as of the last day of the Plan Year in
                       which the Participant's employment terminates.  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 Within Five Years of Reemployment - Repayments 
                       Permitted:
                       -----------------------------------------------------

                       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.

                       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,





                                                                            (33)
<PAGE>   42
                       (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;

                       (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:





                                                                            (34)
<PAGE>   43
                       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 disability which satisfies
       the requirements for benefit entitlement under the Social Security Act
       and any long term disability plan or program sponsored by the Employer.

       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.

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.





                                                                            (35)
<PAGE>   44
              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.

       (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 between the
              date the deceased Participant would have reached age 59 1/2, and
              December 31 of the calendar year in which the deceased
              Participant would have attained age 70 1/2.  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 benefit payable to a
              Beneficiary under this Section does not exceed $3,500,
              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.





                                                                            (36)

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 earlier of:

       (a)    the date the Participant terminates employment;  or

       (b)    the later of:

                 (i)   the date the Participant attains age 50, or
                (ii)   the earliest date the Participant is entitled to a
                       distribution under the Plan,

       provided 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 at the
       earliest possible date described above.

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

       (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:





                                                                            (37)
<PAGE>   46
                 (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

       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.





                                                                            (38)
<PAGE>   47
7.14   MANDATORY PAYMENT OF DISTRIBUTIONS TO CERTAIN PARTICIPANTS AT AGE 70 1/2

       Notwithstanding anything in the Plan to the contrary, distribution of
       Plan benefits shall commence no later than April 1 following the Plan
       Year in which the Participant attains age 70 1/2, regardless of whether
       the Participant has retired; provided, however, that any Participant who
       attained age 70 1/2 on or before January 1, 1988 and who was not a 5%
       owner of the Employer (as defined in Section 416(i)(1)(B) of the Code)
       in the Plan Year in which he attained age 66 1/2 or in any succeeding
       Plan Year, may elect to defer the commencement of his benefits until his
       actual date of retirement.  For purposes of this paragraph, any
       Participant who on January 1, 1989 remains actively employed by the
       Employer after having attained age 70 1/2 during 1988, and who is not a
       5% owner of the Employer, shall be treated as having retired on January
       1, 1989; benefits payable to such Participant shall commence no later
       than April 1, 1990.

7.15   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 Employee's or former Employee's spouse or former spouse
              who is 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





                                                                            (39)
<PAGE>   48
              includable in gross income (determined without regard to the 
              exclusion for net unrealized appreciation with respect to 
              employer securities).

      (c)     Eligible Retirement Plan means a plan described below:

                (i)  an individual retirement account described in Section
                     408(a) of the Code;

               (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
       rollover must total $500 or more.

       Direct rollovers shall be accomplished in accordance with procedures
       established by the Benefits Committee.





                                                                            (40)

              Committee on a form designated for that purpose by the Benefits
              Committee.  Decisions by the Benefits Committee regarding Loans

              days from the date the Loan application is received by the
              Benefits Committee.

8.2     LOAN CONDITIONS

        A Plan Loan shall be subject to the following conditions:

       (a)    A new Plan Loan shall not be made to an applicant until he fully
              repays any previous Plan Loan.

       (b)    The minimum Loan shall be $1,000.

       (c)    The maximum Loan amount shall be based upon the vested balance in
              the applicant's Total Account as of the Valuation Date preceding
              the date the Loan is made.

       (d)    Each Loan shall bear interest at a rate equal to 1% point above
              the United States Treasury rate for an instrument with a similar
              maturity to that of the Plan Loan on the date the Plan Loan
              request is made.  Notwithstanding the foregoing, the Plan Loan
              interest shall conform to the amount necessary to comply with
              Department of Labor Regulation 2550.408b- 1(e).

       (e)    Each Loan shall be secured by collateral consisting of the
              applicant's vested interest in his Total Account, supported by a
              promissory note for the amount of the Loan, made payable to the
              Trustee.





                                                                            (42)
<PAGE>   51
       (f)    In applying for a Loan, the applicant shall agree to repay the
              Loan plus interest over a period of years from one to five, as
              elected by the Participant, unless the Loan is to be used for the
              purchase of the Participant's principal place of residence, in
              which case the repayment period may be any period of years up to
              fifteen years, as elected by the Participant.

       (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 shall commence with the first
              paycheck received by the 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).  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)    The portion of an individual's Total Account constituting a Loan
              shall be segregated into a separate fund, which shall be known as
              the individual's Loan Fund.  The Loan Fund as of any Valuation
              Date shall equal the sum of the following components:

                 (i)   the principal amount due his Supplemental Before-Tax
                       Contribution Account;

                (ii)   the principle amount due his Basic Before-Tax 
                       Contribution Account;

               (iii)   the principal amount due his Cash Option Deferred
                       Account;

                (iv)   the principal amount due his Rollover Account;





                                                                            (43)
<PAGE>   52
                 (v)   the principal amount due his Employer Matching
                       Contribution Account; and

                (vi)   the principal amount due his Regular Profit Sharing
                       Account.

              Each of the above amounts shall be increased with its
              proportionate share of interest charged to the Loan Fund.

       (b)    As of each Valuation Date, the balance of the Loan Fund shall be
              reduced by the payments made since the previous Valuation Date.
              Loan repayments shall be applied in the reverse order designated
              in paragraph (a) above.

       (c)    Loan repayments shall be allocated among the investment funds in
              the same percentage as the individual's most recent investment
              election in effect under the Plan, except that loan repayments to
              the Regular Profit Sharing Account shall be invested in the UST
              Managed Growth Retirement Fund.

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:





                                                                            (44)

                             THE BENEFITS COMMITTEE


9.1      ESTABLISHMENT AND COMPOSITION

         The general administration of the Plan and the responsibility for
         carrying out its provisions shall be vested in the Benefits Committee,
         which shall be composed of at least three persons appointed from time
         to time by the Board.  The Benefits Committee shall be the "NAMED
         FIDUCIARY" of the Plan in accordance with Section 402(a) of ERISA.
         Any one or more of the members of such Committee may be officers or
         directors of the Employer and need not be Participants in the Plan.

         The Trustee shall accept and rely upon a certification by the Board as
         to the number and identity of the individuals comprising the Benefits
         Committee at any time at its sole discretion.  A person appointed to
         be a member of such Committee shall signify his acceptance to the
         Board in writing.  He may resign by delivering his written resignation
         to the Board and such resignation shall become effective upon its
         delivery or any later date specified therein.

         If at any time there shall be a vacancy in the membership of the
         Benefits Committee, the remaining member or members of the Committee
         shall continue to act until such vacancy is filled by action of the
         Board.  The Benefits Committee shall appoint from among its members a
         chairman, and may appoint as secretary a person who may, but need not
         be, a member of the Benefits Committee or a Participant in the Plan.

9.2      MEETINGS

         The Benefits Committee shall hold meetings upon such notice, at such
         place or places, and at such times as its members may from time to
         time determine.  A simple majority or three, whichever is less, of the
         members of the Benefits Committee at the time in office shall
         constitute a quorum for the transaction of business.  All action taken
         by the Benefits Committee at any meeting shall be by vote of the
         simple majority of its members present at such meeting at which a
         quorum is present, but the Benefits Committee may act without a
         meeting by unanimous action of its members evidenced by a writing
         signed by all such members;  provided, however, that no member of such





                                                                            (46)
<PAGE>   55
         Committee shall take any part in any action relating solely to himself
         or to his rights or benefits under the Plan.

9.3      BY-LAWS

         Subject to the terms of the Plan, the Benefits Committee may from time
         to time adopt by-laws, rules and regulations for the administration of
         the Plan and the conduct and transaction of its business and affairs.

8.4      POWERS AND DUTIES

         The Benefits Committee shall have and shall exercise complete
         discretionary authority to discharge its duties hereunder, including,
         but not limited to, the authority to interpret and construe the Plan
         to determine all questions of eligibility, duration of service, dates
         of birth, participation or retirement, allocation of benefits, value
         of benefits, and similarly related matters for the purpose of the
         Plan, the authority to prescribe forms to be used for designating
         Beneficiaries or 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 Board as it deems appropriate in order to
         administer the Plan.  Any such construction, administration,
         interpretation or application shall be final, binding and conclusive
         upon all persons concerned.  All matters falling outside the scope of
         the powers and duties of the Benefits Committee, and not otherwise
         provided for in the Plan, shall be referred to the Board which shall
         have the power to act thereon.

9.5      RECORDS

         All acts and determinations by the Benefits Committee shall be duly
         recorded, and all such records, together with such other documents as
         may be necessary for the administration of this Plan, shall be
         preserved in the custody of the Benefits Committee.

9.6      INSTRUCTIONS

         The Benefits Committee shall, from time to time, issue written
         instructions to the Trustee with respect to the payments to be made
         out of the Fund pursuant to the Plan.





                                                                            (47)
<PAGE>   56
9.7      AUTHORITY TO SIGN

         From time to time, the Benefits Committee may authorize one or more of
         its members to execute any or all documents on behalf of such
         Committee and shall notify the Trustee in writing of the names of the
         persons so designated.  The Trustee shall accept and rely upon any
         document executed by the person or persons so designated as
         representing action by the Benefits Committee until receipt from such
         Committee of a written revocation of such designation.

9.8      ADMINISTRATION

         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.

9.9      PAYMENT OF EXPENSES

         The Employer shall upon receipt of notice thereof from the Benefits
         Committee promptly pay the operation and administrative expenses of
         such 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.

9.10     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.

9.11     DISCLOSURE

         The Benefits Committee shall cause to be furnished to each Participant
         a written summary of the Plan and any amendment thereto.  Such summary
         shall include the names of the members of the Benefits Committee and
         the name of the Trustee, and shall set forth the Participant's rights
         and duties with respect to the benefits available to him





                                                                            (48)
<PAGE>   57
         under the Plan.  Any decisions of the Benefits Committee respecting an
         Employee's or Participant's right to be included in the Plan or to
         benefits hereunder shall be delivered to the Employee or Participant
         in writing.

9.12     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 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, grant the 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 120 days after the
         request for such 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.

9.13     COMPLIANCE IN GENERAL

         The Benefits Committee shall exercise such authority and
         responsibility as it deems appropriate in order to comply with ERISA
         and governmental regulations issued thereunder relating to records of
         Participant's service, Total Account balances and the percentage of
         such Total Account balances which are nonforfeitable under the Plan,
         notifications to Participants, registration with the Internal Revenue
         Service, and reports to the Department of Labor.

9.14     INVESTMENT POLICY

         Although the Trustee shall have the sole responsibility for the
         specific investments chosen for the assets of the Trust Fund, the
         Benefits Committee shall have the authority to establish general
         investment policy guidelines that the Trustee shall rely upon in the
         choice of investments for the Trust Fund.  Such directions or
         guidelines shall be contained in a document or documents executed by
         such person or persons as are authorized to sign on behalf of the
         Benefits Committee pursuant to Section 9.7.





                                                                            (49)
<PAGE>   58
9.15     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)

                                    TRUSTEE


10.1     INVESTMENT RESPONSIBILITY

         The responsibility for investment of the Trust Fund assets shall rest
         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.

         In the absence of any direction to the contrary from the Benefits
         Committee, 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.





                                                                            (51)
<PAGE>   60
10.2     INVESTMENT DIRECTION BY THE BENEFITS COMMITTEE

         The Benefits Committee may establish certain investment policy
         guidelines for the Trustee.  Such authority shall include directions
         to both purchase and sell such securities.  The Trustee will not be
         responsible for any loss incurred with respect to any investment made
         or retained pursuant to any such direction or instructions, and the
         Trustee shall not have any responsibility or duty to approve, review,
         or follow the advisability of sale, retention or disposal of such
         directed investment, nor to determine if any direction is consistent
         with the purpose of the Plan and/or applicable law and shall not be
         subject to any liability for action taken or omitted in reliance on
         advice of counsel.

10.3     CUSTODY

         The Trustee shall have the exclusive responsibility for custody of the
         Trust Fund, including any income, from and after the receipt of an
         Employer Contribution or other addition to the Trust Fund.

10.4     DISBURSEMENTS AND DISTRIBUTIONS

         The Trustee shall make disbursements for the purposes of investment
         pursuant to the direction of the Benefits Committee and in the absence
         of such direction as the Trustee in its sole discretion deems
         advisable and proper, provided, however, that such disbursement
         decisions shall be made in a manner consistent with the general
         investment policy guidelines established by the Benefits Committee
         pursuant to Section 10.2.  The Trustee shall make disbursements for
         the payment of expenses upon approval by the Benefits Committee, and
         the Trustee shall have no other responsibility with respect to such
         disbursements.  The Trustee shall make distributions to Participants
         and their Beneficiaries in accordance with the written instructions of
         the Benefits Committee, observing the names, addresses and other
         similar instructions given by such Committee, and the Trustee shall
         have no other responsibility with respect to such distributions.

10.5     ALLOCATION OF RESPONSIBILITIES AMONG TRUSTEES REGARDING PLAN ASSETS

         If there shall be more than one Trustee, the Trustees shall jointly
         manage and control the assets of the Trust Fund, except that with the
         approval of the Benefits Committee the Trustees may by 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.





                                                                            (52)
<PAGE>   61
10.6     FIDUCIARY STATUS

         The Trustee is a fiduciary and shall be free from interference by the
         Employer with the discharge of its duties as set forth in the Plan and
         the requirements of law.  The Benefits Committee may remove the
         Trustee for any reasons which the Benefits Committee, in its sole
         discretion, deems sufficient.

10.7     ADMINISTRATIVE EXPENSES;  ADVISORS

         All administrative expenses of the Plan shall be charged to and paid
         by the Employer.  In the event that they are not so paid, such
         expenses shall be charged to and paid out by the Trust Fund provided,
         however, that all of the Trustee's administrative fees and expenses
         may be charged against the Trust Fund without the prior approval of
         the Benefits Committee.  The Benefits Committee shall not approve any
         expense whose payment would be inconsistent with the obligations of a
         fiduciary under ERISA or would constitute a prohibited transaction
         thereunder.  Expenses payable hereunder include, without limitation,
         Trustees' fees, actuarial, accounting and legal fees, appraisal
         expenses incurred in the valuation of securities, and fees for
         investment or insurance advice.  The Benefits Committee, the Employer
         and the Trustee may employ persons to render accounting, legal,
         appraisal, investment or insurance advice and may rely upon such
         advice.

10.8     RESIGNATION

         The Trustee may resign upon 30 days' prior written notice to the 
         Benefits Committee.

10.9     TRUSTEE'S MISCELLANEOUS POWERS

         The Trustee shall have the following powers exercisable without leave
         of court and without limiting any power otherwise given to the
         Trustee:

         (a)   VOTING.  The Trustee may vote all securities held in the Trust
               Fund either directly or by proxy.

         (b)   TRANSFERS.  The Trustee may buy, sell, mortgage, grant a
               security interest in, lease (for any length of time) or
               otherwise deal with 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





                                                                            (53)
<PAGE>   62
               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.

         (c)   CONTRACTS.  The Trustee may make contracts binding upon the
               trust estate without assuming personal liability therefor.

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

         (e)   CLAIMS.  The Trustee may pay a claim on such proof as the
               Trustee deems sufficient and may compromise disputed claims of
               or against the Trustee on such terms as the Trustee deems
               adequate.

         (f)   BANKING TRANSACTIONS.  The Trustee may authorize one or more
               persons to sign checks and other commercial paper and engage in
               banking transactions on behalf of the Trust Fund.  A Trustee
               which is a bank may use its own banking facilities, to the
               extent permitted by law, for deposits of funds of the Trust
               Fund.

10.10    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, unless protested by written notice to
         the Trustee within 60 days of receipt thereof by the Benefits
         Committee.

         The Trustee or the Benefits Committee shall have the right to apply at
         any time to a court of competent jurisdiction for judicial settlement
         of any account of the Trustee not





                                                                            (54)
<PAGE>   63
         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.

10.11    INDEMNIFICATION OF TRUSTEE

         The Employer and the Benefits Committee 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.





                                                                            (55)

                                                                            (56)

                        (a)(iii) above if "1%" were substituted for "5%" in 
                        each place where it appears in paragraph (a)(iii).

                        A Key Employee shall be determined in accordance with
                        the provisions of Section 416(i) of the Code and the

         (c)   "DETERMINATION DATE" means the last day of the preceding Plan
               Year, except that for the first Plan Year the Determination Date

         (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.





                                                                            (57)
<PAGE>   66
         (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).

         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.

         (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.





                                                                            (58)
<PAGE>   67
         (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:

                  (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





                                                                            (59)
<PAGE>   68
                        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 shall be taken
               into account in satisfying the minimum allocation provisions of
               paragraph (b) above.





                                                                            (60)
<PAGE>   69
         (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.





                                                                            (61)

                           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.





                                                                            (62)
<PAGE>   71
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:


                                                                            (63)
<PAGE>   72
                  (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

                (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 



                                                                            (64)
<PAGE>   73
                     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) above shall be held unallocated in a suspense
               account for such Limitation Year, and shall be reallocated in
               the next Limitation Year to the


                                                                            (65)
<PAGE>   74
         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
               defined benefit plans (whether or not terminated) maintained by
               the Employer,


                                                                            (66)
<PAGE>   75
               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


                                                                            (67)
<PAGE>   76
                        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 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.



                                                                            (68)
<PAGE>   77
         (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


                                                                            (69)

               Total 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


                                                                            (70)
<PAGE>   79
                        the Actual Contribution Percentage for such Nonhighly 
                        Compensated Employees.

         (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.


                                                                            (71)
<PAGE>   80
               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.


                                                                            (72)
<PAGE>   81
               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:





                                                                            (73)
<PAGE>   82
                              (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.





                                                                            (74)

                          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 established a separate qualified plan for its
         employees.  If a separate qualified plan





                                                                            (75)

         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 22nd day of March, 1994.

         (c)   The reduction of a Highly Compensated Employee's Actual Deferral
               Percentage shall be made in accordance with the following
               procedure:

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

                      (ii)  Excess contributions (and income allocable thereto)
                            shall be returned, distributed, or, if applicable,
                            forfeited, within 2 1/2 months of the beginning of
                            the next Plan Year, if practicable, but in no event
                            no later than the last day of the Plan Year
                            following the close of the Plan Year in which such
                            excess arose.

                            The following method shall be used to determine the
                            income allocable on excess contributions
                            accumulated from the last day of the Plan Year in
                            which the excess contributions arose to the date of
                            distribution of such excess ("gap period"):

                            The income on the excess contributions for the gap
                            period shall equal 10% of the income earned in the
                            Plan Year in which the excess arose multiplied by
                            the number of calendar months contained in the gap
                            period to the date of distribution of such excess.
                            A distribution of the excess occurring on one of
                            the first fifteen days of a calendar month shall be
                            deemed to have been made on the last day of the
                            preceding month.  A distribution occurring after
                            the fifteenth day of a calendar month shall be
                            deemed to have been made on the first day of the
                            next succeeding calendar month.

         (d)   Notwithstanding anything in the Plan to the contrary and to the
               extent permitted by applicable law, the Plan may be restructured
               into component parts based on employee groups or any other
               methods permitted by applicable law for a Plan Year in order to
               determine whether the Plan meets the Code Section 401(k)
               nondiscrimination requirements and/or the Code Section 401(a)(4)
               nondiscrimination requirements for such year.

of the Committee shall be appointed by the Board and shall serve at the
pleasure of the Board.

        The Committee shall have the power and authority, in its discretion:

        (i)     to select Participants from among those employees of the
                Company and the Subsidiaries who are Eligible Employees;

        (ii)    to determine whether and to what extent Stock Options,
                Restricted Stock, or any combination of the foregoing, are to
                be granted to Eligible Employees hereunder; 


JMZSTCOM.US                   -2-
<PAGE>   3
        (iii)   to determine the number of shares of Stock to be covered by
                each such award granted hereunder;

         (iv)   to determine the terms and conditions, not inconsistent with
                the terms of the Plan, of any award granted hereunder; and

          (v)   to determine the terms and conditions of any written
                instruments evidencing Stock Options, Restricted Stock, or any
                combination of the foregoing awarded under the Plan.

        The Committee shall have the authority to adopt, alter and repeal such
administrative rules, guidelines and practices governing the Plan as it shall,
from time to time, deem advisable; to interpret the terms and provisions of the
Plan and any award issued under the Plan (and any agreements relating thereto);
and to otherwise supervise the administration of the Plan.

        All decisions made by the Committee pursuant to the provisions of the
Plan shall be final and binding on all persons, including the Company and the
Participants.


SECTION 3:  STOCK SUBJECT TO PLAN

        Subject to adjustment in accordance with the third and fourth
paragraphs of this Section 3, the maximum number of shares of Stock reserved
and available for awards made under the Plan in any calendar year shall be
equal to (i) 1 1/4% of the total number of shares of Stock outstanding as of
the beginning of that year, plus (ii) any unused portion of the annual limit
for prior years.  In determining the number of shares available in 1994 and any
carryover from 1994, the number of shares determined under (i) above for 1994
shall be increased by 350,000.  Notwithstanding the foregoing, no more than
1,000,000  shares of Stock in the aggregate (subject to adjustment under the
third and fourth paragraphs of this Section 3) may be issued pursuant to the
exercise of Incentive Stock Options under the Plan.

        Subject to adjustment in accordance with the fourth paragraph of this
Section 3, no Participant may be awarded, in any calendar year, Stock Options
covering more than 175,000 shares.  For purposes of the immediately preceding
sentence, the repricing of a Stock Option shall be treated as a new award and
shall count against the specified share limit.  The provisions of this
paragraph and of the proviso set forth in the immediately following paragraph
shall apply to awards of Stock Options under the Plan only to the extent
required in order for Stock Options under the Plan to qualify
                                   

JMZSTCOM.US                         -3-
<PAGE>   4
for the performance-based compensation exception described in Section
162(m)(4)(C) of the Code.

        To the extent that a Stock Option expires or is otherwise terminated
without being exercised, or shares of Restricted Stock are forfeited, the
shares of Stock underlying such Stock Option or the forfeited shares of
Restricted Stock, as the case may be, shall again be available for issuance in
connection with future awards under the Plan; provided, that any such future
award of a Stock Option (if made to the same Participant and in the same year
as the award of the expired or terminated Stock Option) shall count against the
annual per-Participant Stock Option award limit described in the preceding
paragraph.

        In the event of any merger, reorganization, consolidation,
recapitalization, stock dividend, or other change in corporate structure
affecting the Stock, the Committee shall make an appropriate adjustment in (i)
the aggregate number of shares of Stock reserved for issuance under the Plan or
for which awards may be made under the Plan, and (ii) the number and Option
Price of shares of Stock subject to outstanding Stock Options granted under the
Plan; provided, that the number of shares of Stock subject to any award shall
always be a whole number.  The Committee may make other substitutions or
adjustments, but no such substitution or adjustment shall be effective if it
would cause any Stock Option previously granted to an individual described in
Section 162(m)(3) of the Code to fail to qualify for the performance-based
compensation exception prescribed by Section 162(m)(4)(C) of the Code; and
further provided, that no such substitution or adjustment shall be effective,
without the Participant's consent, if it would cause the Incentive Stock
Options status of any Stock Option held by the Participant to be impaired.

        Shares issued pursuant to Plan awards may consist in whole or in part
of authorized and unissued shares or of treasury shares.


SECTION 4:  ELIGIBILITY

        Officers and other key employees of the Company or Subsidiaries who
are responsible for or contribute to the growth and/or profitability of the
business of the Company or its Subsidiaries shall be eligible to be granted
awards hereunder.  The Participants under the Plan shall be selected from time
to time by the Committee from among those Eligible Employees, and the Committee
shall determine the number of shares of Stock covered by each award.


JMZSTCOM.US                          -4-
<PAGE>   5
SECTION 5:  STOCK OPTIONS

        Stock Options may be granted alone, in addition to or in combination
with other awards granted under the Plan.  Any Stock Option granted under the
Plan shall be in such form as the Committee may from time to time approve, and
the provisions of Stock Option awards need not be the same with respect to each
Participant.  Recipients of Stock Options shall enter into a stock option
agreement with the Company, in such form as the Committee shall determine,
which agreement shall set forth, either expressly or by incorporation of the
terms of the Plan, among other things, the Option Price, the term of the Stock
Option and provisions regarding exercisability of the Stock Option granted
thereunder.

        Stock Options granted under the Plan may be of two types: (i)
Incentive Stock Options and (ii) Non-Qualified Stock Options.  The Committee
shall have the authority to grant any Participant Incentive Stock Options,
Non-Qualified Stock Options, or both types of Stock Options.  Only those Stock
Options specifically designated as Incentive Stock Options shall be treated as
such; all other Stock Options shall be treated as Non-Qualified Stock Options.

        Stock Options granted under the Plan shall be subject to the following
terms and conditions and shall contain such additional terms and conditions,
not inconsistent with the terms of the Plan, as the Committee may determine:

        (a)     OPTION PRICE.  The Option Price per share of Stock purchasable
                under a Stock Option shall be determined by the Committee at
                the date of grant but in the case of an Incentive Stock Option
                shall be not less than 100% of the Fair Market Value of the
                Stock on such date.

        (b)     OPTION TERM.  The term of each Stock Option shall be fixed by
                the Committee, but no Stock Option shall be exercisable more
                than ten years after the date such Stock Option is granted.

        (c)     EXERCISABILITY.  Stock Options shall be exercisable at such
                time or times and subject to such terms and conditions as
                shall be determined by the Committee at or after grant.  If
                the Committee may accelerate the exercisability of a Stock
                Option at any time, to such extent as it may determine.


JMZSTCOM.US                          -5-
<PAGE>   6
        (d)     TIMING AND METHOD OF EXERCISE.  The exercise of a Stock Option
                shall be accomplished by giving written notice of exercise to
                the Company specifying the number of shares of Stock to be
                purchased, accompanied by payment in full of the Option Price
                in cash or check, by surrender of other shares of Stock which
                have been held by the Participant for six months or more (or
                for such other period as the Committee may determine) and
                which have a value equal to the Option Price of the shares of
                Stock as to which the Stock Option is being exercised, by
                delivery of a properly executed exercise notice together with
                irrevocable instructions to the Participant's broker to
                deliver promptly to the Company the amount of sale proceeds
                required to pay the Option Price, or by any combination of the
                foregoing.  The Company shall, prior to the delivery of any
                shares of Stock subject to an exercise, make arrangements for
                the payment of withholding taxes, if any, as provided in
                Section 9(d).

        (e)     NON-TRANSFERABILITY OF OPTIONS.  No Incentive Stock Option
                shall be transferable by the Participant otherwise than by
                will or by the laws of descent and distribution, and all
                Incentive Stock Options shall be exercisable, during the
                Participant's lifetime, only by the Participant.  Nonqualified
                Stock Options shall be transferable (i) only to the extent, if
                any, determined by the Committee, and (ii) in the case of any
                such Stock Option the grant of which is intended to be exempt
                under Rule 16b-3 promulgated under the Securities Exchange Act
                of 1934, as amended, only to the extent, if any, that
                transferability is permitted (consistent with such exemption)
                by such Rule.

        (f)     TERMINATION BY REASON OF DEATH.  If a Participant's employment
                with the Company or any Subsidiary terminates by reason of
                death, any Stock Option held by the Participant at time of
                death may thereafter be exercised, to the extent exercisable
                immediately prior to death (or on such accelerated basis as
                the Committee shall determine at or after grant), by the legal
                representative of the estate or by the legatee of the
                Participant under the will of the Participant, for a period of
                one year (or such shorter period as the Committee shall
                specify at grant) from the date of such death or until the
                expiration of the stated term of such Stock Option, whichever
                period is shorter.

        (g)     TERMINATION BY REASON OF DISABILITY.  If a Participant's
                employment with the Company or any 


JMZSTCOM.US                          -6-
<PAGE>   7
                Subsidiary terminates by reason of Disability, any Stock
                Option held by such Participant may thereafter be exercised to
                the extent it was exercisable at the time of such termination
                (or on such accelerated basis as the Committee shall determine
                at or after grant), for a period of one year (or such shorter
                period as the Committee shall specify at grant) from the date
                of such termination of employment or until the expiration of
                the stated term of such Stock Option, whichever period is
                shorter, provided, however, that, if the Participant dies
                within such one-year period (or such shorter period as the
                Committee shall specify at grant), any unexercised Stock
                Option held by such Participant shall thereafter be
                exercisable to the extent to which it was exercisable at the
                time of death for a period of one year (or such shorter period
                as the Committee shall specify at grant) from the time of such
                death or until the expiration of the stated term of such Stock
                Option, whichever period is shorter.

         (h)    OTHER TERMINATION.  Except as otherwise provided in this
                Section 5, unless otherwise determined by the Committee, if a
                Participant's employment with the Company or any Subsidiary
                terminates for any reason other than death or Disability, the
                Stock Option may thereafter be exercised to the extent it was
                exercisable at the time of such termination (or on such
                accelerated basis as the Committee shall determine at or after
                grant) for the lesser of three months from the date of
                termination or until the expiration of such Stock Option's
                term; provided, that if the Participant's employment is
                terminated for cause, all Stock Options then held by the
                Participant shall terminate immediately.


SECTION 6:  RESTRICTED STOCK

         (a)    GENERAL.  Restricted Stock may be issued either alone or in
                addition to other awards granted under the Plan.  The
                Committee shall determine the Eligible Employees to whom, and
                the time or times at which, grants of Restricted Stock will be
                made; the number of shares of Stock to be awarded; the price,
                if any, to be paid by the recipient of Restricted Stock; any
                performance objectives applicable to Restricted Stock awards;
                the date or dates on which restrictions applicable to such
                Restricted Stock shall lapse during the Restricted Period (as
                defined at Section 6(c)(i) below); and all other conditions of
                the Restricted Stock awards.  The performance


JMZSTCOM.US                          -7-
<PAGE>   8
                objectives, if any, to which a grant of Restricted Stock may
                be subject may include, without limitation, objectives based
                on the performance of the Company, the performance of one or
                more Subsidiaries, the performance of one or more divisions or
                other business segments, personal performance, or external
                performance measures, all as determined by the Committee.  The
                Committee may also condition the grant of Restricted Stock
                upon the exercise of Stock Options or upon such other criteria
                as the Committee may determine.  The provisions of Restricted
                Stock awards need not be the same with respect to each
                recipient.

         (b)    AWARDS AND CERTIFICATES.  The prospective recipient of an
                award of shares of Restricted Stock shall not have any rights
                with respect to such award, unless and until such recipient
                has executed an agreement evidencing the award (a "Restricted
                Stock Award Agreement") and has delivered a fully executed
                copy thereof to the Company, within a period of 60 days (or
                such other period as the Committee may specify) after the
                award date.  The stock certificate or certificates issued in
                respect of shares of Restricted Stock shall be registered in
                the name of the Participant and shall bear an appropriate
                legend referring to the terms, conditions, and restrictions
                applicable to such award, substantially in the following form:

                        "The transferability of this certificate and the 
                        shares of stock represented hereby are subject to 
                        the terms and conditions (including forfeiture) of 
                        the UST Corp. Stock Compensation Plan and a 
                        Restricted Stock Award Agreement entered into
                        between the registered owner and UST Corp.  Copies of
                        such Plan and Agreement are on file in the offices of
                        UST Corp."

         The Committee may require that the stock certificates evidencing such
         shares of Stock be held in the custody of the Company until the
         restrictions thereon shall have lapsed, and that, as a condition of
         any Restricted Stock award, the Participant shall have delivered a
         stock power, endorsed in blank, related to the Stock covered by such
         award.

         (c)     RESTRICTIONS AND CONDITIONS.  The shares of Restricted Stock
awarded pursuant to this Section 6


JMZSTCOM.US                          -8-

<PAGE>   9
                 shall be subject to the following restrictions and conditions:

         (i)     Subject to the provisions of the Plan and the Restricted Stock
                 Award Agreement, during such period as may be set by the
                 Committee commencing on the grant date (the "Restricted
                 Period"), the Participant shall not be permitted to sell,
                 transfer, pledge or assign shares of Restricted Stock awarded
                 under the Plan.  In the case of a Restricted Stock award
                 providing for the lapsing of restrictions only upon the
                 attainment of performance related goals, the Restricted Period
                 shall be deemed to continue until such performance related
                 goals have been met.  Within these limits, the Committee may
                 provide for the lapse of restrictions in installments and may
                 accelerate or waive such restrictions in whole or in part
                 based on such factors and such circumstances as the Committee
                 may determine, including, but not limited to, the attainment
                 of performance related goals, the Participant's termination of
                 employment, death or Disability, or the occurrence of a
                 "Change of Control" as defined in Section 8 below.

         (ii)    Except as provided in clause (c)(i) above, the Participant
                 shall have, with respect to the shares of Restricted Stock,
                 all of the rights of a stockholder of the Company, including
                 the right to vote the shares and the right to receive any
                 dividends thereon.  Certificates for shares of unrestricted
                 Stock shall be delivered to the Participant as soon as
                 practicable after the Restricted Period expires without such
                 shares of Stock having been forfeited.  The Company's
                 obligation to deliver vested shares of Stock upon the
                 expiration of the Restricted Period (whether in the normal
                 course or on an accelerated basis as described in the
                 preceding paragraph) shall be subject to the Company's being
                 satisfied that arrangements for the payment of withholding
                 taxes, if any, as provided in Section 9(d) have been made.

         (iii)   Subject to the provisions of the Restricted Stock Award
                 Agreement and this Section 6, upon termination of employment
                 for any reason during the Restricted Period, all shares of
                 Stock still subject to restriction shall be forfeited by the
                 Participant, and the Participant shall only

<PAGE>   10
                receive the amount, if any, paid by the 
                Participant for such Restricted Stock.


SECTION 7:  AMENDMENT AND TERMINATION

        The Board may amend, alter, or discontinue the Plan at any time;
provided, that no such amendment or alteration shall be effective without the
approval of the stockholders to the extent that stockholder approval is
required to preserve the qualification of the Plan under Section 162(m)(4)(C)
or Section 422 of the Code or its exemption under Rule 16b-3 promulgated under
the Securities Exchange Act of 1934, as amended.  The Committee may, consistent
with the terms of the Plan, prospectively or retroactively amend the terms of
any previously granted award.  In no event, however, shall any amendment or
alteration (whether affecting the Plan generally or particular awards) impair
the rights of any Participant under any then outstanding award without the
consent of such Participant.


SECTION 8:  CHANGE OF CONTROL

        The following acceleration and valuation provisions shall apply in the
event of a "Change of Control" as defined in this Section 8:

          (a)     As of the date of the "Change of Control":

          (i)     any Stock Options awarded under the Plan not previously
                  exercisable and vested shall become fully exercisable and
                  vested;

          (ii)    the restrictions applicable to any Restricted Stock awarded
                  under the Plan shall lapse and such shares shall be deemed
                  fully vested; and

          (iii)   any Participant to whom a Stock Option shall have been granted
                  shall have the right (subject to any legal limitations
                  applicable to such Stock Option, including any limitations
                  required to preserve the qualification under Section 422 of
                  the Code of any such Stock Option that is an Incentive Stock
                  Option) to receive in respect of such Stock Option, and in
                  extinguishment thereof, for each share of Stock subject to
                  such Stock Option an amount equal to the excess of (x) the
                  "Change of Control Price" (as defined in paragraph (c) of this
                  Section 8) of the securities, cash or other property, or
                  combination thereof, which would be received in


JMZSTCOM.US                          -10-
<PAGE>   11
                connection with the transaction giving rise to the Change of
                Control in respect of a share of Stock, over (y) the Option
                Price of such Stock Option, unless provision is made in
                connection with such transaction for the substitution for such
                Stock Option of new options of the successor corporation or
                parent thereof, with appropriate adjustments as to the number
                and kind of shares and the per share Option Price as provided
                in Section 3 hereof.

         (b)    For purposes of paragraph (a) of this Section 8, a "Change of
Control" shall be deemed to have occurred if:

         (i)    any "person," as such term is used in Sections 13(d) and 14(d)
                of the Securities and Exchange Act, (the "Exchange Act")
                (other than the Company, any trustee or other fiduciary
                holding securities under an employee benefit plan of the
                Company, or any company owned, directly or indirectly, by the
                stockholders of the Company in substantially the same
                proportions as their ownership of stock of the Company), is or
                becomes the "beneficial owner" (as defined in Rule 13d-3 under
                the Exchange Act), directly or indirectly, of securities of
                the Company representing 25% or more of the combined voting
                power of the Company's then outstanding securities;

         (ii)   during any period of two consecutive years (not including any
                period prior to the execution of the Plan), 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 (i), (iii) or (iv) of this
                Section 8(b)) whose election by the Board or nomination for
                election by the Company's stockholders was approved by a vote
                of at least two-thirds (2/3) 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 (hereinafter referred to as "Continuing
                Directors"), cease for any reason to constitute at least a
                majority thereof;

         (iii)  the stockholders of the Company approve 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


JMZSTCOM.US                          -11-
<PAGE>   12
                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 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
                25% of the combined voting power of the Company's then
                outstanding securities shall not constitute a Change of
                Control of the Company; or

         (iv)   the stockholders of the Company approve a plan of complete
                liquidation of the Company or an agreement for the sale or
                disposition by the Company of all or substantially all of the
                Company's assets.

         (c)    For purposes of this Section 8, "Change of Control Price"
                means the higher of (i) the highest price per share paid or
                offered in any transaction related to a Change of Control of
                the Company or (ii) the highest price per share paid in any
                transaction reported on the exchange on which the Stock is
                traded at any time during the sixty-day period preceding the
                Change of Control, as determined by the Committee; provided,
                however, that, in the case of Incentive Stock Options such
                price shall not be the higher of the foregoing items (i) and
                (ii), but shall be the Fair Market Value of the securities,
                cash or other property, or combination thereof, which would be
                received in connection with the transaction on the date of
                such Change of Control.


SECTION 9:  GENERAL PROVISIONS

         (a)    The Committee may require each person purchasing shares of
                Stock pursuant to a Stock Option to represent to and agree
                with the Company in writing that such person is acquiring the
                shares of Stock without a view to distribution thereof.  The
                certificates for such shares of Stock may include any legend
                which the Committee deems appropriate to reflect any
                restrictions on transfer.

         (b)    All certificates for shares of Stock delivered under the Plan
                shall be subject to such stock-transfer 


JMZSTCOM.US                          -12-
<PAGE>   13
                orders and other restrictions as the Committee may deem
                advisable under the rules, regulations, and other requirements
                of the Securities and Exchange Commission, any stock exchange
                upon which the Stock is then listed, and any applicable
                Federal or state securities law, and the Committee may cause a
                legend or legends to be put on any such certificates to make
                appropriate references to such restrictions.

         (c)    Nothing contained in the Plan shall prevent the Board from
                adopting other or additional compensation arrangements,
                subject to stockholder approval if such approval is required;
                and such arrangements may be either generally applicable or
                applicable only in specific cases.  The adoption of the Plan
                shall not confer upon any employee of the Company or any
                Subsidiary any right to continued employment with the Company
                or a Subsidiary, as the case may be, nor shall it interfere in
                any way with the right of the Company or a Subsidiary to
                terminate the employment of any of its employees at any time.

         (d)    Each Participant shall, no later than the date as of which the
                value of an award first becomes includible in the gross income
                of the Participant for Federal income tax purposes, pay to the
                Company, or make arrangements satisfactory to the Company
                regarding payment of, any Federal, state, or local taxes of
                any kind required by law to be withheld with respect to the
                award.  The obligations of the Company under the Plan shall be
                conditional on such payment or arrangements and the Company
                (and, where applicable, its Subsidiaries) shall, to the extent
                permitted by law, have the right to deduct any such taxes from
                any payment of any kind otherwise due to the Participant.

                determination, or interpretation taken or made in good faith
                with respect to the Plan, and all members of the Board or the
                Committee and each and any officer or employee of the Company
                acting on their behalf shall, to the extent permitted by law,

                                   UST CORP.

                      1995 STOCK OPTION PLAN FOR DIRECTORS

1.   PURPOSE

The purpose of this 1995 Stock Option Plan for Directors (the "Plan") is to
advance the interests of UST Corp. (the "Company") by enhancing the ability of
the Company and certain of its subsidiaries to attract and retain non-employee
directors who are in a position to make significant contributions to the
success of the Company and to reward directors for such contributions through
ownership of shares of the Company's common stock (the "Stock").


2.  ADMINISTRATION

 The Plan shall be administered by a committee (the "Committee") of the Board
of Directors (the "Board") of the Company designated by the Board for that
purpose.  The Committee shall have authority, not inconsistent with the express
provisions of the Plan, (a) to issue options granted in accordance with the
formula set forth in this Plan to such directors as are eligible to receive
options; (b) to prescribe the form or forms of instruments evidencing options
and any other instruments required under the Plan and to change such forms from
time to time; (c) to adopt, amend and rescind rules and regulations for the
administration of the Plan; and (d) to interpret the Plan and to decide any
questions and settle all controversies and disputes that may arise in
connection with the Plan.  Such determinations of the Committee shall be
conclusive and shall bind all parties.  Transactions under this plan are
intended to comply with all applicable conditions of Rule 16b-3 or its
successors under Section 16 of the Securities Exchange Act of 1934 (the
"Exchange Act").  To the extent any provision of the Plan or action by the
Committee fails to so comply, it shall be deemed null and void, to the extent
permitted by law and deemed advisable by the Committee.


3.  EFFECTIVE DATE AND TERM OF PLAN

The Plan shall become effective on the date on which the Plan is approved by
the Board of Directors of the Company, subject to approval by the stockholders
of the Company.  No option shall be granted under the Plan after the completion
of ten years from the date on which the Plan was adopted by the Board, but
options previously granted may extend beyond that date.


4.  SHARES SUBJECT TO THE PLAN

      (a)   NUMBER OF SHARES.  Subject to adjustment as provided in 
            Section 4(c), the

                 upon the exercise of options granted under the Plan shall be
                 150,000. If any option granted under the Plan terminates
                 without having been exercised in full, the number of shares
                 of Stock as to which such option was not exercised shall be
                 available for future grants within the limits set forth in
                 this Section 4(a).

         (b)     SHARES TO BE DELIVERED.  Shares delivered under the Plan shall
                 be authorized but unissued Stock or previously issued Stock
                 acquired by the Company and held in treasury.  No fractional
                 shares of Stock shall be delivered under the Plan.

         (c)     CHANGES IN STOCK.  In the event of a stock dividend, stock
                 split or combination of shares, recapitalization or other
                 change in the Company's capital stock, after the effective
                 date of the Plan, the number and kind of shares of stock or
                 securities of the Company subject to options then outstanding
                 or subsequently granted under the Plan, the maximum number of
                 shares or securities that may be delivered under the Plan, the
                 exercise price, the "prescribed number" specified in Section
                 6(a), and other relevant provisions shall be appropriately
                 adjusted by the Committee, whose determination shall be
                 binding on all persons.

emeritus directors) of the Company who are not employees of the Company or of
any subsidiary of the Company, and (b) those directors (not including honorary
or emeritus directors) of USTrust who are not employees of the Company or of
any subsidiary of the Company.


6.  TERMS AND CONDITIONS OF OPTIONS

         (a)     NUMBER OF OPTIONS.  On the date of the annual meeting of
                 stockholders at which this Plan is approved by stockholders
                 each individual then an Eligible Director shall be awarded on
                 such date an option covering shares of Stock equal in number
                 to the "prescribed number" as hereinafter defined.
                 Thereafter, on the date of each subsequent annual meeting,
                 there shall be awarded to each individual elected at such
                 meeting to serve as an Eligible Director and to each other
                 Eligible Director (if any) elected to office since the last
                 annual meeting by the board of directors of the corporation on
                 which he or she serves as a director, but excluding any
                 Eligible Director who has previously been granted options
                 under this Plan, an option covering the prescribed number of
                 shares of Stock.  For purposes of this paragraph, the
                 "prescribed number" is: (i) 7,500 in the case of any Eligible
                 Director (other than an honorary director of the Company)
                 serving as a director both of the Company and of USTrust; (ii)
                 5,100 in the case of any Eligible Director (other than an
                 honorary director of the Company) serving as a director


                                      2
<PAGE>   3
                 of the Company but not serving as a director of USTrust;
                 (iii) 4,500 in the case of any Eligible Director serving as
                 an honorary director of the Company; and (iv) 3,000 in the
                 case of any Eligible Director serving as a director of
                 USTrust but not serving as a director of the Company (other
                 than as an honorary director of the Company).  The 
                 "prescribed number" for an Eligible Director described in
                 both (iii) and (iv) shall be 7,500.

         (b)     EXERCISE PRICE.  The exercise price of each option shall be
                 100% of the fair market value per share of the Stock on the
                 date the option is granted.  In no event, however, shall the
                 option price be less, in the case of an original issue of
                 authorized stock, than par value per share.  For purposes of
                 this paragraph, the fair market value of a share of Stock on
                 any date shall be the average of the high and low prices of
                 the Stock on the NASDAQ National System on such date, or if
                 the Stock did not trade on such date, on the next preceding
                 day on which trades were made.

         (c)     DURATION OF OPTIONS.  The latest date on which an option may
                 be exercised (the "Final Exercise Date") shall be the fifth
                 anniversary of the date the option was granted.

         (d)     Exercise of Options.
                 -------------------

                 (1)      Each option shall become exercisable as follows: (A)
                          to the extent of one-third (1/3) of the shares
                          covered by the option, on the earliest testing date
                          (as hereinafter defined) on which the per-share fair
                          market value of the Stock is at least three dollars
                          ($3.00) higher than on the date of grant; (B) to the
                          extent of an additional one-third (1/3) of the
                          shares, on the earliest testing date on which the
                          per-share fair market value of the Stock is at least
                          six dollars ($6.00) higher than on the date of grant;
                          and (C) to the extent of an additional one-third
                          (1/3) of the shares, on the earliest testing date on
                          which the per- share fair market value is at least
                          nine dollars ($9.00) higher than on the date of
                          grant.  For purposes of the preceding sentence, a
                          "testing date" with respect to any per-share dollar
                          value is the last day of any period of ten
                          consecutive trading days (commencing after the date
                          on which the Plan is approved by the stockholders of
                          the Company) on each day of which the per-share fair
                          market value of the Stock equaled or exceeded such
                          dollar value; provided, that a date shall not be
                          considered a "testing date" for purposes of
                          determining the exercisability of an option under
                          this paragraph if the director to whom the option was
                          awarded ceased to be a director of the Company and
                          its subsidiaries prior to the testing date.  In all
                          events, each option shall become fully exercisable on
                          the third anniversary of the date of grant provided
                          the Eligible Director to whom the option was awarded
                          is still a director on such anniversary.  For
                          purposes of the preceding sentence, the following
                          rules of construction shall apply:  (A) with respect


                                            3
<PAGE>   4
                          to any option grants described in Section 6(a)(iii),
                          an Eligible Director described therein shall be
                          treated as ceasing to be a director when he or she is
                          no longer an Eligible Director described inSection
                          5(a); (B) with respect to any option grants described
                          in Section 6(a)(iv), an Eligible Director described
                          therein shall be treated as ceasing to be a director
                          when he or she is no longer an Eligible Director
                          described in Section 5(b); and (C) with respect to
                          any option grants described in Section 6(a)(i) or
                          Section 6(a)(ii), an Eligible Director described
                          therein shall be treated as ceasing to be a director
                          when he or she ceases to be a director of the Company
                          or becomes an honorary or emeritus director of the
                          Company.

                          In addition to and not in limitation of the
                          foregoing, each option outstanding at the time of a
                          "Change of Control" as hereinafter defined shall
                          become fully exercisable upon the Change in Control.
                          A "Change of Control" shall be deemed to have
                          occurred if:

                          (i)     any "person," as such term is used in
                                  Sections 13(d) and 14(d) of the Securities
                                  and Exchange Act, (the "Exchange Act") (other
                                  than the Company, any trustee or other
                                  fiduciary holding securities under an
                                  employee benefit plan of the Company, or any
                                  company owned, directly or indirectly, by the
                                  stockholders of the Company in substantially
                                  the same proportions as their ownership of
                                  stock of the Company), is or becomes the
                                  "beneficial owner" (as defined in Rule 13d-3
                                  under the Exchange Act), directly or
                                  indirectly, of securities of the Company
                                  representing 25% or more of the combined
                                  voting power of the Company's then
                                  outstanding securities;

                          (ii)    during any period of two consecutive years
                                  (not including any period prior to the
                                  adoption of the Plan), 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

                                  (iii) or (iv) of this Section 6(d)(1)) whose
                                  election by the Board or nomination for
                                  election by the Company's stockholders was
                                  approved by a vote of at least two-thirds
                                  (2/3) of the directors then still in office

                                  the period or whose election or nomination
                                  for election was previously so approved
                                  (hereinafter referred to as "Continuing
                                  Directors"), cease for any reason to

                          (iii)   the stockholders of the Company approve 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 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

                             (as hereinabove defined) acquires more than
                             25% of the combined voting power of the
                             Company's then outstanding securities shall
                             not constitute a Change of Control of the
                             Company; or

                             plan of complete liquidation of the Company
                             or an agreement for the sale or disposition

                 (2)   Any exercise of an option shall be in writing, signed
                       by the proper person and delivered or mailed to the
                       Company, to the attention of the Company's General
                       Counsel, accompanied by (i) any documentation
                       required by the Committee and (ii) payment in full
                       for the number of shares for which the option is
                       exercised.
                       
                 (3)   The Committee shall withhold from the number of

                       exercise a number of shares with a fair market value
                       equal to any federal, state, or local withholding tax
                       requirements due upon the exercise of the option.
                       
                 (4)   If an option is exercised by the executor or
                       administrator of a deceased director, or by the
                       person or persons to whom the option has been
                       transferred by the director's will or the applicable
                       laws of descent and distribution, the Company shall
                       be under no obligation to deliver Stock pursuant to
                       such exercise until the Company is satisfied as to
                       the authority of the person or persons exercising the
                       option.
                       
           (e)   PAYMENT FOR AND DELIVERY OF STOCK.  Stock purchased under the
                 Plan shall be paid for in one or a combination of the

                 six months) having a fair market value on the last business
                 day preceding the date of exercise equal to the purchase

                 An option holder shall not have the rights of a stockholder
                 with regard to awards under the Plan except as to Stock
                 actually received by him or her under the Plan.

                 The Company shall not be obligated to deliver any shares of
                 Stock (A) until, in the opinion of the Company's counsel, all
                 applicable federal and state laws and regulations have been
                 complied with, and (B) if the outstanding Stock is at the time
                 listed on any stock exchange, until the shares to be delivered
                 have been listed or authorized to be listed on such exchange
                 upon official notice of issuance, and (C) until all other
                 legal matters in connection with the issuance and delivery of
                 such shares have been approved by the Company's counsel.  If
                 the sale of Stock has not been registered under the Securities
                 Act of 1933, as amended, the Company may require, as a
                 condition to exercise of the option, such representations or
                 agreements as counsel for the Company may consider appropriate
                 to avoid violation of such Act and may require that the
                 certificates evidencing such Stock bear an appropriate legend
                 restricting transfer.

         (f)     NONTRANSFERABILITY OF OPTIONS.  No option may be transferred
                 other than by will or by the laws of descent and distribution,
                 and during an Eligible Director's lifetime an option may be
                 exercised only by him or her.

         (g)     RETIREMENT; DISABILITY.  If an Eligible Director retires as a
                 director of the Company and its subsidiaries (i) at or after
                 65, or (ii) by reason of permanent disability whenever
                 occurring, all options held by the retired or disabled
                 Eligible Director, to the extent not otherwise exercisable,
                 shall become exercisable.  The Eligible Director's options
                 shall remain exercisable for one year from retirement (subject
                 to paragraph (i) below) or for the remainder of their original
                 five-year option term if less, and then shall terminate to the
                 extent not previously exercised.

         (h)     OTHER TERMINATION.  If an Eligible Director's service as a
                 director terminates for any reason other than retirement under
                 (g) above or death, all options held by the director that are
                 not then exercisable shall terminate.  Options that are
                 exercisable on the date of termination shall continue to be
                 exercisable for a period of three months (subject to paragraph
                 (i) below) or for the remainder their original five-year term
                 if less, and then shall terminate to the extent not previously
                 exercised.  For the purposes of this paragraph (h):  (A) with
                 respect to any option grants described in Section 6(a)(iii),
                 an Eligible Director described therein shall be treated as
                 having terminated when he or she ceases to be an Eligible
                 Director described in Section 5(a) (other than by reason of
                 retirement under paragraph (g) above, or death); (B) with
                 respect to any option grants described in Section 6(a)(iv), an
                 Eligible Director described therein shall be treated as having
                 terminated when he or she ceases to be an Eligible Director
                 described in Section 5(b) (other than by reason of retirement
                 under paragraph (g) above, or death); and (C) with respect to
                 any option grants described in Section 6(a)(i) or Section
                 6(a)(ii), an Eligible Director  described therein shall be
                 treated as having



                                      6
<PAGE>   7
              terminated when he or she ceases to be a director of the
              Company (other than by reason of retirement under paragraph
              (g) above, or death) or becomes an honorary or emeritus
              director of the Company.
      
      (i)     DEATH.  If an Eligible Director's service as a director of the
              Company and its subsidiaries terminates by reason of death,
              all options held by the Eligible Director which were not then
              exercisable shall be treated as having become exercisable
              immediately prior to death.  If an Eligible Director dies at
              any time while holding exercisable options (including options
              treated as having become exercisable by reason of the
              preceding sentence), all such options may be exercised by his
              or her executor or administrator, or by the person or persons
              to whom the option is transferred by will or the applicable
              laws of descent and distribution, at any time within one year
              after the director's death or during the remainder of the
              original five-year option term if less.  After completion of
              that one-year (or shorter) period, such options shall
              terminate to the extent not previously exercised.
      
      
      (j)     MERGERS, ETC.  In the event of a consolidation or merger in
              which the Company is not the surviving corporation or which
              results in the acquisition of substantially all the Company's
              outstanding Stock by a single person or entity or by a group
              of persons and/or entities acting in concert, or in the event
              of a sale or transfer of substantially all of the Company's
              assets or a dissolution or liquidation of the Company, all
              options hereunder will terminate; provided, that 20 days prior
              to the effective date of any such merger, consolidation, sale,
              dissolution, or liquidation, all options outstanding hereunder
              that are not otherwise exercisable shall become immediately
              exercisable.
      
      
7.    EFFECT, DISCONTINUANCE, CANCELLATION, AMENDMENT, TERMINATION AND
      EFFECTIVENESS
      
Neither adoption of the Plan nor the grant of options to a director shall
affect the Company's right to grant to such director options that are not
subject to the Plan, to issue to such directors Stock as a bonus or otherwise,
or to adopt other plans or arrangements under which Stock may be issued to
directors.

The Committee may at any time terminate the Plan as to any further grants of
options.  The Committee may at any time or times amend the Plan for any purpose
which may at the time by permitted by law; provided, that except to the extent
expressly required or permitted by the Plan, no such amendment will, without
the approval of the stockholders of the Company, effectuate a change for which
stockholder approval is required in order for the Plan to continue to qualify
under Rule 16b-3 promulgated under Section 16 of the Exchange Act.

                               AMENDMENT NO. 1 TO
                          EMPLOYMENT AGREEMENT BETWEEN
                         UST CORP. AND NEAL F. FINNEGAN
                         ------------------------------

         This Agreement, dated as of August 2, 1993, constitutes Amendment No.
1 to the Employment Agreement (the "Agreement"), dated as of April 20, 1993, by
and between UST Corp. ("UST"), a bank holding company with its principal place
of business in Boston, Massachusetts, and Neal F. Finnegan, a resident formerly
of Rowayton, Connecticut and now of Cohasset, Massachusetts (the "Employee").

                                   WITNESSETH
                                   ----------
                                                                
         WHEREAS, UST wishes to strengthen certain of the stock compensation
elements of the Employee's Agreement with UST in order to more directly align
the economic interests of the Employee with those of UST's stockholders; and

         WHEREAS, the additional stock compensation and reduced stock option
exercise prices provided by this Amendment No. 1 to the Agreement have been
recommended to UST by UST's investment banking advisors, Fox-Pitt, Kelton
Limited and are desired by and acceptable to the Employee, and

         WHEREAS, UST and the Employee desire to conform Employee's
remuneration with respect to business use of automobiles and clubs to UST's
general policy of reimbursement for senior executives as of January 1, 1994.

         NOW THEREFORE, in consideration of the premises and the mutual
covenants contained in the Agreement as modified by this Amendment No. 1, the
parties do hereby agree as follows:
<PAGE>   2
         1.  The second paragraph of Article II of the Agreement is hereby
amended so that the revised paragraph reads in its entirety as follows:

                 "Moreover, the Employee will be granted by UST's Board of
         Directors, stock options under UST Corp.'s Stock Compensation Plan
         (the "Plan") having the terms described herein which will enable the
         Employee to purchase up to an aggregate of 150,000 shares (subject to
         anti-dilution provisions ) of UST Corp. Common Stock.  Such options
         shall vest (subject to a change-in-control) at a rate of 50,000 shares
         per year over three years with each 50,000 share annual segment having
         five (5) parts: 13,333 shares exercisable at a price of $7.50 per
         share; 16,667 shares exercisable at $8 per share; 3,333 shares
         exercisable at $9 per share; 6,667 shares exercisable at $10 per
         share; and 10,000 shares exercisable at $12 per share.  Any options
         which are exercisable at a price lower than the fair market value of
         UST Common Stock on the date of grant shall be nonstatutory options;
         options with prices equal to or higher than such fair market value
         beginning with the lowest such prices, subject to the limits of
         applicable law and regulation, shall be incentive stock options."

         2.      An additional paragraph will be added to Article II of the
Agreement and inserted between the current second and third paragraphs of the
Agreement.  This new, additional paragraph (which results in Article II as
modified having five paragraphs) will read in its entirety as follows:

                 "In addition to the foregoing, UST's Board of Directors will,
         effective January 3, 1994, grant the Employee stock options under UST
         Corp.'s Stock Compensation Plan which will enable the Employee to
         acquire an additional 200,000 shares of UST Corp. Common Stock at an
         exercise price of $9.00 per share.  These Options will vest 1/3 on
         April 20, 1994, 1/3 on April 20, 1995 and 1/3 on April 20, 1996,
         unless vesting is accelerated in accordance with the provisions of the
         Stock Compensation Plan."

         3.      The first paragraph of Article II of the Agreement is hereby
amended to delete the third and fourth sentences of such first paragraph.  The
foregoing sentences related to UST payments to Employee for business use of an
automobile and annual dues at the Bay Club as well as at one country

club.  The Employee shall, in accordance with revised UST exclusive
compensation policies (and effective on the dates of the respective
implementation of such policies), in lieu of such payment receive an upward
salary adjustment to reflect the reasonable value of such benefits surrendered.

         IN WITNESS WHEREOF, the parties hereto have cause this Amendment No. 1
to the Agreement to be executed in duplicate originals as of the date first
written above.

                   Separation Agreement for Theodore Shediac
                   -----------------------------------------


Mr. Theodore M. Shediac                                   April 6, 1994
52 Old Nugent Rd.
Gloucester, MA 01930

Dear Ted:

         As we have discussed and agreed, your employment with UST Corp. and
its affiliated companies (collectively "UST") will terminate on June 30, 1994
and you will be paid through UST's payroll system through that date. The
purpose of this letter agreement is to set forth the terms and conditions
related to your separation from UST.

         1.      Salary continuation: Salary will continue for 12 months after
                 June 30, 1994. The form of payment will be in one lump sum of
                 $268,500 payable to you during the first week of July 1994.

         2.      Continuation of benefits: USTrust will continue to pay the
                 life insurance premiums on your current policy through June
                 30, 1994. Thereafter, if coverage is to continue, you will
                 have to convert the policy to an individual contract.
                 Disability insurance provided through USTrust will cease as of
                 your termination date.

                 Medical insurance premiums will continue to be paid to provide
                 coverage for you and your family under the Baystate Health
                 Care plan, through June 30, 1994. During this period, you will
                 continue to pay normal monthly contributions of $128.65.
                 Effective July 1, 1994, you will be able to continue medical
                 insurance coverage through COBRA for up to 18 months.

         3.      Vested profit sharing: You will be paid the account balance
                 credited to you under the company's profit sharing plan after
                 the 6/30/94 valuation. It is understood that as of 6/30/93
                 your vested balance was $214,520.33. It is further understood
                 that at the time of the valuation and payout, these amounts
                 may be higher or lower depending on the valuation.

         4.      Vested ESOP: You will be paid out the value of your vested
                 ESOP account after the 6/30/94 valuation. It is understood
                 that as of 6/30/93 your vested balance was 6,028.9514 shares
                 plus a cash balance of $79.26. It is further understood that
                 at the time of the valuation and payout, these amounts may be
                 higher or lower depending on the valuation.
<PAGE>   2
         5.      It is understood that you are 100% vested in the USTrust
                 qualified retirement plan. A schedule has been provided to
                 you, indicating the projected pay-out amounts at age 65.

         6a.     Incentive stock options (ISO): You will receive acceleration
                 of unvested Incentive Stock Options so that as of June 30,
                 1994, you will be fully vested in 18,375 shares at a purchase
                 price of $6.0714 and 5,000 shares at a purchase price of
                 $8.625. Your options expire 3 months after your termination
                 date.

         6b.     Restricted stock: As of June 30, 1994, you will be vested in
                 5,433 shares of restricted stock.

                 The value of the vested shares, determined as of the vesting
                 date, will be includible in your income for federal income tax
                 and Massachusetts tax purposes, and will be treated as "wages"
                 subject to withholding for employment tax (including FICA)
                 purposes, as of the time of vesting. A certificate
                 representing the vested shares will be delivered to you once
                 you have made arrangements satisfactory to the Company to pay
                 all required withholding taxes.  You may satisfy this
                 withholding obligation by: (i) providing a certified or bank
                 check to the Company for the required withholding taxes, or
                 (ii) delivering stock powers to the Company authorizing the
                 sale of sufficient shares to pay the withholding taxes.

                 It is further understood that there are limitations on your
                 ability to sell these newly acquired shares in UST Corp.
                 stock. Shares must be held for six months after the date of
                 termination (i.e. after 6/30/94).

         7.      The above matter was presented to the UST Corp. Board of
                 Directors on March 15, 1994 and was preliminarily approved.
                 Pending a third party certification by The Wyatt Co. and a
                 definitive vote scheduled for April 19, 1994 of Board approval
                 based upon the Wyatt certificate, the above matters will be
                 subject only to the written approval of the Federal Reserve
                 Bank of Boston and the Massachusetts Commissioner of Banks.

         8.      Attached to this letter agreement as EXHIBIT A is a General
                 and Specific Release signed by you which releases UST Corp.
                 and its successors, assigns, subsidiaries, and its and their
                 respective officers, directors, employees, agents and
                 representatives from various liabilities and claims. The
                 foregoing Release, attached as EXHIBIT A, is incorporated into
                 this letter agreement and made a part hereof.

                          General and Specific Release
                          ----------------------------

FOR AND IN CONSIDERATION of payments to be made to me in connection with my
separation of employment, as set out in the Separation Agreement between UST
Corp. and me, dated March 31, 1994, I, Theodore M. Shediac, hereby release UST
Corp. ("UST") and its successors, assigns, subsidiaries and its and their
respective officers, directors, employees, agents and representatives (all
collectively, "Releases") from any and all liability, claims, demands, actions,
causes of action of any type by reason of any matter, cause, act or omission
arising out of or in connection with my employment or separation from
employment with UST Corp.  and/or its subsidiaries, including without
limitation, claims, demands or actions under Title VII of Civil Rights Act of
1964, as amended, the Rehabilitation Act of 1973, the Civil Rights Act of 1866,
the Massachusetts Fair Employment Practices Act, and any other Federal, state
or local statute or regulation regarding employment, discrimination in
employment or termination of employment; and I, Theodore M. Shediac, shall at
no time take any action that I am aware is inconsistent with this Release;
provided that I am not releasing and shall not be deemed to have released (i)
any claim arising under the terms of the Separation Agreement or the terms of
UST's employee pension plan, profit sharing plan, or stock ownership plan, each
as amended to the effective time of my termination of employment, or (ii) any
right of indemnification or contribution that may exist at or may arise after
such effective time and that I am or may be entitled to enforce against UST 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 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
upon this Release, UST promises that neither it nor any other of the Releases
affiliated with UST, will take any action that is designed, specifically with

        termination (i.e. after 1/31/95) at which time you will cease to be
        deemed an Executive Officer of UST Corp.

8.      The above matter was presented to the UST Corp. Board of Directors on
        March 15, 1994 and was preliminarily approved.  Pending a third party
        certification by The Wyatt Co. and a definitive vote scheduled for

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

         In the event the Employee either (i) shall, without cause, leave his
employment at least 90 days prior to the end of the term hereof, or (ii) shall
be discharged for cause during the term hereof, the Employee agrees that he
will not enter into the employment of any other financial institution or entity
in Eastern Massachusetts or Southern Connecticut for a period equal to one
year. The foregoing restriction will not be applicable in the event that the
Employee is terminated as a result of disability as enumerated in Article V
above. The Employee further agrees that for a period of two years following the
termination of his employment for whatever reason hereunder, 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, UST Corp.

financial service, or (ii) after notice from UST Corp. or UST that any person

available to him in the course of his employment hereunder confidential
information of or relating to UST and its affiliates, including, without
limitation, client and customer lists, acquisition, expansion, and other
strategic plans (collectively the "Confidential Information"). The Employee
hereby acknowledges that the Confidential Information, as it may exist from
time to time, is a valuable, special and unique asset of the business of UST,
UST Corp. and their affiliates. UST hereby acknowledges that the Employee may,
in the performance of his duties obtain information of a general nature
concerning UST and its affiliates, which could be obtained by any person having
an interest in UST and its affiliates, and which general information is not
deemed included within the meaning of Confidential Information. The Employee
shall not, during or after the term of his employment hereunder, make any use
of Confidential Information or disclose any Confidential Information to any
person, firm, corporation, association or other entity for any reason or

injunctive relief, restraining the Employee from disclosing or using any
Confidential Information in violation of this Article VII, and to recover any
and all costs and expenses incurred in enforcing this Employment Agreement, in
addition to any other relief provided by applicable law.  The Employee
acknowledges that the nature of the business of UST and the value of the
Confidential Information render inadequate any remedy at law which may be
obtained by UST or any of its affiliates for a breach by the Employee of this
Articie VII and the Employee therefore hereby agrees that UST or any of its
affiliates may seek such equitable remedies.

                                   UST CORP.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and Walter E. Huskins, Jr.  (the "Employee") as of
the 24th day of October, 1994 (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 continue the employment of
the Employee, and the Employee agrees to continue in the service of 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, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, 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 such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and 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 or its designees.

                 b.       During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the 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 the Company and
its subsidiaries.
<PAGE>   2
         4.      COMPENSATION.  As compensation for all services performed for
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, 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/her duties for the Company 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/her 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/her 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/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her 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.

<PAGE>   3
                 d.       BY THE COMPANY OTHER THAN FOR CAUSE.  The Company may
terminate the Employee's employment other than for Cause at any time upon
notice to the Employee.  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/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) 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. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her 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) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will 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

                          iii.  The Company shall pay the cost of outplacement
                 services for the Employee through a firm selected by the
                 Employee (and reasonably acceptable to the Company), up to a
                 maximum cost to the Company of not more than $20,000; it being
                 understood and agreed that no payment will be provided to the
                 Employee in lieu of outplacement services.

                 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; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another executive position; (iii) 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 (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her work site on the
Effective Date.

In the event of termination in accordance with this Section 6.e, the Company
shall provide the Employee base salary 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/her 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 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/her 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/her 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

                                  (1)  shall pay the Employee 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 the Company's regular payroll
         periods and in accordance with its regular payroll practices
         commencing on the next regular payday immediately following the final
         payment under Section 6.d or 6.e hereof, whichever is applicable,

                                  (2) provided the Employee elects to receive
         payment hereunder in the form of salary continuation and provided
         further that the Employee has exercised his/her right to continue
         participation in the Company's group health plan under applicable
         federal law ("COBRA"), then, for the duration of the period in which
         the Employee is receiving such salary continuation or, if earlier,
         until the date the Employee ceases to be eligible for continued
         participation under COBRA, the Company shall continue to pay that
         share of the premium cost of Employee's participation and that of
         his/her eligible dependents in the Company's group health plan as it
         pays for active employees of the Company and their eligible dependents
         generally or, if greater, the amount it was paying for active
         employees of the Company and their eligible dependents generally
         immediately prior to the Change of Control and

                                  (3) shall pay the cost of outplacement
         services for the Employee through a firm selected by the Employee (and

         no payment will be provided to the Employee in lieu of outplacement
         services.

                          ii.     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 affiliates or any trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or any of its
         subsidiaries or 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.  In the event
that the term of this Agreement expires and, at the time of such expiration,
the Company has not offered to extend or renew this Agreement on terms no less
favorable in the aggregate as those set forth herein, then such expiration
shall be treated as a termination by the Company of the Employee's employment
other than for Cause in accordance with Section 6.d hereof.  In the event that
the Company has 

                                      5
<PAGE>   6
offered such extension or renewal prior to the expiration of the term hereof, 
but such offer has not been accepted by the Employee at the time of such 
expiration, then such expiration 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
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company 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/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and 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 affiliates and the
people and organizations with whom any of them has business relationships and
those relationships.  Confidential Information also includes any information
received by the Company or any of its subsidiaries or 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 for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she 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.

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 or subsidiaries and (b) the payments and

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/she
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.     MISCELLANEOUS.  This Agreement sets forth the entire agreement

Employee's employment.  The headings and captions contained herein are for

                                  UST CORP.
                                      
                        EXECUTIVE EMPLOYMENT AGREEMENT


        This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and James K. Hunt (the "Employee") as of the 24th
day of October, 1994 (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 continue the employment of
the Employee, and the Employee agrees to continue in the service of 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, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, 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 such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and 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 or its designees.

                b.   During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the 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 the Company and
its subsidiaries.
<PAGE>   2
         4.      COMPENSATION.  As compensation for all services performed for
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, 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/her duties for the Company 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/her 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/her 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/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her 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.

<PAGE>   3
                 d.       BY THE COMPANY OTHER THAN FOR CAUSE.  The Company may
terminate the Employee's employment other than for Cause at any time upon
notice to the Employee.  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/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) 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. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her 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) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will 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

                          iii.  The Company shall pay the cost of outplacement
                 services for the Employee through a firm selected by the
                 Employee (and reasonably acceptable to the Company), up to a
                 maximum cost to the Company of not more than $20,000; it being
                 understood and agreed that no payment will be provided to the
                 Employee in lieu of outplacement services.

                 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 continuethe Employee in an executive position; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another exeuctive position; (iii) 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 (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her work site on the
Effective Date.

<PAGE>   4
In the event of termination in accordance with this Section 6.e, the
Company shall provide the Employee base salary 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/her 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 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/her 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/her 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

                                  (1)  shall pay the Employee 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 the Company's regular payroll
         periods and in accordance with its regular payroll practices
         commencing on the next regular payday immediately following the final
         payment under Section 6.d or 6.e hereof, whichever is applicable,

                                  (2) provided the Employee elects to receive
         payment hereunder in the form of salary continuation and provided
         further that the Employee has exercised his/her right to continue
         participation in the Company's group health plan under applicable
         federal law ("COBRA"), then, for the duration of the period in which
         the Employee is receiving such salary continuation or, if earlier,
         until the date the Employee ceases to be eligible for continued
         participation under COBRA, the Company shall continue to pay that
         share of the premium cost of Employee's participation and that of
         his/her eligible dependents in the Company's group health plan as it
         pays for active employees of the Company and their eligible dependents
         generally or, if greater, the amount it was paying for active
         employees of the Company and their eligible dependents generally
         immediately prior to the Change of Control and

                                  (3) shall pay the cost of outplacement

         no payment will be provided to the Employee in lieu of outplacement

                          ii.     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 affiliates
        or any trustee or other fiduciary holding securities under an 
        employee benefit plan of the Company or any of its subsidiaries or 
        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.  In the event that the term
of this Agreement expires and, at the time of such expiration, the Company 
has not offered to extend or renew this Agreement on terms no less favorable 
in the aggregate as those set forth herein, then such expiration shall be 
treated as a termination by the Company of the Employee's employment other 
than for Cause in accordance with Section 6.d hereof.  In the event that the 
Company has 

                                     -5-
<PAGE>   6
offered such extension or renewal prior to the expiration of the term
hereof, but such offer has not been accepted by the Employee at the time of
such expiration, then such expiration 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
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company 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/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and 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 affiliates and the
people and organizations with whom any of them has business relationships and
those relationships. Confidential Information also includes any information
received by the Company or any of its subsidiaries or 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 for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she 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.

                                     -6-

         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 affiliates or subsidiaries 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/she
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.     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.  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, its term may not be extended or

                                                          EXHIBIT 10(v)(iii)
                                   UST CORP.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and Eric R. Fischer (the "Employee") as of the
24th day of October, 1994 (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 continue the employment of
the Employee, and the Employee agrees to continue in the service of 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, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, 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 such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and 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 or its designees.

                 b.       During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the 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 the Company and
its subsidiaries.
<PAGE>   2
         4.      COMPENSATION.  As compensation for all services performed for
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, 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/her duties for the Company 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/her 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/her 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/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her 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 at any time upon
notice to the Employee.  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/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) 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. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her 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) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will 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

                          iii.  The Company shall pay the cost of outplacement
                 services for the Employee through a firm selected by the
                 Employee (and reasonably acceptable to the Company), up to a
                 maximum cost to the Company of not more than $20,000; it being
                 understood and agreed that no payment will be provided to the
                 Employee in lieu of outplacement services.

                 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; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another executive position; (iii) 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 (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her work site on the
Effective Date.





                                      -3-
<PAGE>   4
In the event of termination in accordance with this Section 6.e, the Company
shall provide the Employee base salary 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/her 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 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/her 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/her 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

                                  (1)  shall pay the Employee an amount equal
         to eighteen (18) 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 the Company's regular payroll periods
         and in accordance with its regular payroll practices commencing on the
         next regular payday immediately following the final payment under
         Section 6.d or 6.e hereof, whichever is applicable,

                                  (2) provided the Employee elects to receive
         payment hereunder in the form of salary continuation and provided
         further that the Employee has exercised his/her right to continue
         participation in the Company's group health plan under applicable
         federal law ("COBRA"), then, for the duration of the period in which
         the Employee is receiving such salary continuation or, if earlier,
         until the date the Employee ceases to be eligible for continued
         participation under COBRA, the Company shall continue to pay that
         share of the premium cost of Employee's participation and that of
         his/her eligible dependents in the Company's group health plan as it
         pays for active employees of the Company and their eligible dependents
         generally or, if greater, the amount it was paying for active
         employees of the Company and their eligible dependents generally
         immediately prior to the Change of Control and

                                  (3) shall pay the cost of outplacement
         services for the Employee through a firm selected by the Employee (and
         reasonably acceptable to the Company), up to a maximum cost to the
         Company of not more than $20,000; it being understood and agreed that
         no payment will be provided to the Employee in lieu of outplacement
         services.

                          ii.     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 affiliates or any trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or any of its
         subsidiaries or affiliates, becomes a beneficial owner (within the

                                  (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.  In the event
that the term of this Agreement expires and, at the time of such expiration,
the Company has not offered to extend or renew this Agreement on terms no less
favorable in the aggregate as those set forth herein, then such expiration
shall be treated as a termination by the Company of the Employee's employment
other than for Cause in accordance with Section 6.d hereof.  In the event that
the Company has





                                      -5-
<PAGE>   6
offered such extension or renewal prior to the expiration of the term hereof,
but such offer has not been accepted by the Employee at the time of such
expiration, then such expiration 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
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company 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/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and 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 affiliates and the
people and organizations with whom any of them has business relationships and
those relationships.  Confidential Information also includes any information
received by the Company or any of its subsidiaries or 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 for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she 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.





                                      -6-
<PAGE>   7
         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 affiliates or subsidiaries 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/she
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.     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.  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, its term may not be extended or
renewed, 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.

         14.     NOTICES.  Any notices provided for in this Agreement shall be

United States mail, postage prepaid, and addressed to the Employee at his last

                                   UST CORP.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and Linda J. Lerner (the "Employee") as of the
24th day of October, 1994 (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 continue the employment of
the Employee, and the Employee agrees to continue in the service of 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, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, 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 such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and 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 or its designees.

                 b.       During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the 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 the Company and
its subsidiaries.
<PAGE>   2
         4.      COMPENSATION.  As compensation for all services performed for
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, 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/her duties for the Company 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/her 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/her 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/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her 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.

<PAGE>   3
                 d.       BY THE COMPANY OTHER THAN FOR CAUSE.  The Company may
terminate the Employee's employment other than for Cause at any time upon
notice to the Employee.  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/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) 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. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her 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) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will 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

                          iii.  The Company shall pay the cost of outplacement
                 services for the Employee through a firm selected by the
                 Employee (and reasonably acceptable to the Company), up to a
                 maximum cost to the Company of not more than $20,000; it being
                 understood and agreed that no payment will be provided to the
                 Employee in lieu of outplacement services.

                 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; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another executive position; (iii) 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 (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her work site on the
Effective Date.





                                      -3-
<PAGE>   4
In the event of termination in accordance with this Section 6.e, the Company
shall provide the Employee base salary 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/her 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 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/her 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/her 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

                                  (1)  shall pay the Employee an amount equal
         to eighteen (18) 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 the Company's regular payroll periods
         and in accordance with its regular payroll practices commencing on the
         next regular payday immediately following the final payment under
         Section 6.d or 6.e hereof, whichever is applicable,

                                  (2) provided the Employee elects to receive
         payment hereunder in the form of salary continuation and provided
         further that the Employee has exercised his/her right to continue
         participation in the Company's group health plan under applicable
         federal law ("COBRA"), then, for the duration of the period in which
         the Employee is receiving such salary continuation or, if earlier,
         until the date the Employee ceases to be eligible for continued
         participation under COBRA, the Company shall continue to pay that
         share of the premium cost of Employee's participation and that of
         his/her eligible dependents in the Company's group health plan as it
         pays for active employees of the Company and their eligible dependents
         generally or, if greater, the amount it was paying for active
         employees of the Company and their eligible dependents generally
         immediately prior to the Change of Control and

                                  (3) shall pay the cost of outplacement
         services for the Employee through a firm selected by the Employee (and
         reasonably acceptable to the Company), up to a maximum cost to the
         Company of not more than $20,000; it being understood and agreed that
         no payment will be provided to the Employee in lieu of outplacement
         services.

                          ii.     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 affiliates or any trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or any of its
         subsidiaries or 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.  In the event
that the term of this Agreement expires and, at the time of such expiration,
the Company has not offered to extend or renew this Agreement on terms no less
favorable in the aggregate as those set forth herein, then such expiration
shall be treated as a termination by the Company of the Employee's employment
other than for Cause in accordance with Section 6.d hereof.  In the event that
the Company has





                                      -5-
<PAGE>   6
offered such extension or renewal prior to the expiration of the term hereof,
but such offer has not been accepted by the Employee at the time of such
expiration, then such expiration 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
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company 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/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and 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 affiliates and the
people and organizations with whom any of them has business relationships and
those relationships.  Confidential Information also includes any information
received by the Company or any of its subsidiaries or 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 for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she 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.





                                      -6-
<PAGE>   7
         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 affiliates or subsidiaries 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/she
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.     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.  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, its term may not be extended or
renewed, 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.

         14.     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

                                  UST CORP.
                                      
                        EXECUTIVE EMPLOYMENT AGREEMENT


         This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and Kenneth L. Sullivan (the "Employee") as of the
24th day of October, 1994 (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 continue the employment of
the Employee, and the Employee agrees to continue in the service of 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, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, 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 such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and 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 or its designees.

                 b.   During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the 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 the Company and
its subsidiaries.

<PAGE>   2
         4.      COMPENSATION.  As compensation for all services performed for
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, 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/her duties for the Company 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/her 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/her 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/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her 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.

<PAGE>   3
                 d.       BY THE COMPANY OTHER THAN FOR CAUSE.  The Company may
terminate the Employee's employment other than for Cause at any time upon
notice to the Employee.  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/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) 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. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her 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) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will 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

                          iii.  The Company shall pay the cost of outplacement
                 services for the Employee through a firm selected by the
                 Employee (and reasonably acceptable to the Company), up to a
                 maximum cost to the Company of not more than $20,000; it being
                 understood and agreed that no payment will be provided to the
                 Employee in lieu of outplacement services.

                 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; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another executive position; (iii) 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 (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her work site on the
Effective Date.

                                     -3-
<PAGE>   4
In the event of termination in accordance with this Section 6.e, the Company
shall provide the Employee base salary 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/her 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 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/her 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/her 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

                                  (1)  shall pay the Employee an amount equal
         to eighteen (18) 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 the Company's regular payroll periods
         and in accordance with its regular payroll practices commencing on the
         next regular payday immediately following the final payment under
         Section 6.d or 6.e hereof, whichever is applicable,

                                  (2) provided the Employee elects to receive
         payment hereunder in the form of salary continuation and provided
         further that the Employee has exercised his/her right to continue
         participation in the Company's group health plan under applicable
         federal law ("COBRA"), then, for the duration of the period in which
         the Employee is receiving such salary continuation or, if earlier,
         until the date the Employee ceases to be eligible for continued
         participation under COBRA, the Company shall continue to pay that
         share of the premium cost of Employee's participation and that of
         his/her eligible dependents in the Company's group health plan as it
         pays for active employees of the Company and their eligible dependents
         generally or, if greater, the amount it was paying for active
         employees of the Company and their eligible dependents generally

         reasonably acceptable to the Company), up to a maximum cost to the
         Company of not more than $20,000; it being understood and agreed that
         no payment will be provided to the Employee in lieu of outplacement
         services.

                          II.     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 affiliates or any trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or any of its
         subsidiaries or 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.  In the event
that the term of this Agreement expires and, at the time of such expiration,
the Company has not offered to extend or renew this Agreement on terms no less
favorable in the aggregate as those set forth herein, then such expiration
shall be treated as a termination by the Company of the Employee's employment
other than for Cause in accordance with Section 6.d hereof.  In the event that
the Company has 

                                     -5-
<PAGE>   6
offered such extension or renewal prior to the expiration of the term hereof,
but such offer has not been accepted by the Employee at the time of such
expiration, then such expiration 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
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company 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/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and 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 affiliates and the
people and organizations with whom any of them has business relationships and
those relationships.  Confidential Information also includes any information
received by the Company or any of its subsidiaries or 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 for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she 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.

                                     -6-
<PAGE>   7
         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 affiliates or subsidiaries 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/she
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.     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.  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, its term may not be extended or
renewed, and no breach of this Agreement shall be deemed to be waived, unless

contract and shall be governed by and construed in accordance with the laws of
the Commonwealth of Massachusetts.

         14.     NOTICES.  Any notices provided for in this Agreement shall be

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

                                   UST CORP.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and Katharine C. Armstrong (the "Employee") as of
the 24th day of October, 1994 (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 continue the employment of
the Employee, and the Employee agrees to continue in the service of 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, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, 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 such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and 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 or its designees.

                 b.       During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the 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

<PAGE>   2

         4.      COMPENSATION.  As compensation for all services performed for
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, 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/her duties for the Company 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/her 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/her 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/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her 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.
<PAGE>   3
                 d.       BY THE COMPANY OTHER THAN FOR CAUSE.  The Company may
terminate the Employee's employment other than for Cause at any time upon
notice to the Employee.  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/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) 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. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her 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) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will 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

                          iii.  The Company shall pay the cost of outplacement
                 services for the Employee through a firm selected by the
                 Employee (and reasonably acceptable to the Company), up to a
                 maximum cost to the Company of not more than $20,000; it being
                 understood and agreed that no payment will be provided to the
                 Employee in lieu of outplacement services.

                 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; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another executive position; (iii) 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 (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her work site on the
Effective Date.  
                


<PAGE>   4
In the event of termination in accordance with this Section 6.e, the Company
shall provide the Employee base salary 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/her 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 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/her 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/her 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

                                  (1)  shall pay the Employee an amount equal
         to eighteen (18) 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 the Company's regular payroll periods
         and in accordance with its regular payroll practices commencing on the
         next regular payday immediately following the final payment under
         Section 6.d or 6.e hereof, whichever is applicable,

                                  (2) provided the Employee elects to receive
         payment hereunder in the form of salary continuation and provided
         further that the Employee has exercised his/her right to continue
         participation in the Company's group health plan under applicable
         federal law ("COBRA"), then, for the duration of the period in which
         the Employee is receiving such salary continuation or, if earlier,
         until the date the Employee ceases to be eligible for continued
         participation under COBRA, the Company shall continue to pay that
         share of the premium cost of Employee's participation and that of
         his/her eligible dependents in the Company's group health plan as it
         pays for active employees of the Company and their eligible dependents
         generally or, if greater, the amount it was paying for active
         employees of the Company and their eligible dependents generally
         immediately prior to the Change of Control and

                                  (3) shall pay the cost of outplacement
         services for the Employee through a firm selected by the Employee (and
         reasonably acceptable to the Company), up to a maximum cost to the
         Company of not more than $20,000; it being understood and agreed that
         no payment will be provided to the Employee in lieu of outplacement
         services.

                   ii.     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 affiliates or any trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or any of its
         subsidiaries or 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.  In the event
that the term of this Agreement expires and, at the time of such expiration,
the Company has not offered to extend or renew this Agreement on terms no less
favorable in the aggregate as those set forth herein, then such expiration
shall be treated as a termination by the Company of the Employee's employment
other than for Cause in accordance with Section 6.d hereof.  In the event that
the Company has 
<PAGE>   6
offered such extension or renewal prior to the expiration of the term hereof,
but such offer has not been accepted by the Employee at the time of such 
expiration, then such expiration 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
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company 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/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and 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 affiliates and the
people and organizations with whom any of them has business relationships and
those relationships.  Confidential Information also includes any information
received by the Company or any of its subsidiaries or 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 for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she 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.
                
                
<PAGE>   7
        
                
        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 affiliates or subsidiaries 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 other person, corporation
or other entity.  The Company requires the personal services of the Employee
and he/she 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.  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.  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, its term may not be extended of
renewed, 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.

        14.  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.

                                   UST CORP.

                               SEVERANCE PAY PLAN
                         (AND SUMMARY PLAN DESCRIPTION)
                                JANUARY 1, 1995


I.       PURPOSE

         This Plan is intended to provide salary continuation to eligible
employees of UST Corp. (the "Company") in the event that their employment is
terminated as provided hereafter due to a reduction in force or a corporate
restructuring or following a Change of Control.  This Plan is intended to
comply with all applicable requirements of the Employee Retirement Income
Security Act of 1974 ("ERISA") and the Regulations promulgated thereunder for
severance pay plans and is to be interpreted in a manner consistent with such
requirements.  This document contains the provisions of the Plan and the
Summary Plan Description.

II.      ELIGIBILITY TO PARTICIPATE

         A.   In order to be eligible to participate in this Plan:

              1.      You must be a regular full-time or part-time employee of
                      the Company.  (Temporary employees as classified by the
                      Company are not eligible to participate in this Plan.)

              2.      You must have completed at least three (3) months of
                      employment with the Company at the time your employment
                      terminates.

III.     QUALIFYING EVENTS

         A.   An employee eligible to participate in this Plan under Section II
              above (a "participating employee") is entitled to receive
              benefits under the Plan only if the employee is on the Company's
              active payroll or on a leave of absence that has been approved in
              writing, with guaranteed reinstatement, at the time his/her
              employment terminates and only if 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 of Control; and





<PAGE>   2
              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.

IV.      EXCLUSIONS

         A.   The following are examples of events in which an employee would
              not qualify for benefits under this Plan:

              1.      The employee resigns or otherwise voluntarily leaves
                      his/her 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, as determined by
                      the Company; 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.

         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 the Plan are determined as follows:

              1.      A participating employee with less than twenty (20) full
                      years of continuous service as of the date the employee's
                      employment terminates shall receive two (2) weeks salary,
                      at the participating employee's final base rate of pay,
                      for each full year of service with the Company as of the
                      date the employee's employment terminates, to a maximum
                      of twenty-six (26) weeks of pay; provided, however, that
                      no participating employee shall receive less than three
                      weeks pay, at that employee's final base rate.


              2.      A participating employee with twenty (20) full years or
                      more of continuous service as of the date the employee's
                      employment terminates shall receive thirty-nine (39)
                      weeks of salary, at the participating employee's final

<PAGE>   3

              3.      In the case of any participating employee employed on a
                      part-time basis, benefits hereunder shall be pro- rated,
                      based on the number of hours the employee is regularly
                      scheduled to work per week.


         B.   Provided that the participating employee elects to receive
              benefits as salary continuation under option 2 of paragraph C 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 health 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 the Company and their eligible dependents
              generally immediately prior to such Change of Control, if
              greater.

         C.   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 date
              of termination of the participating employee's employment 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 regular payday immediately following the
              date of termination of the participating employee's employment.

         D.   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.

         E.   The Company pays the full cost of benefits provided under this
              Plan from the Company's general assets.

         F.   Benefits under the 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.

         G.   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

              2.      "Cause" for termination means only (i) the employee's
                      refusal to perform or gross negligence in the performance
                      of, his/her duties and responsibilities for the Company
                      or (ii) the employee's fraud, embezzlement or other

                      from the Company setting forth in reasonable detail the
                      nature of such Cause.

              3.      A "Change of Control" shall be deemed to have been
                      consummated if hereafter

                               (i) 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 affiliates or any trustee or
                      other fiduciary holding securities under an employee

                      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

                               (ii) during any period of two consecutive years
                      (not including any period prior to the establishment of
                      this Plan), individuals who at the beginning of such
                      period constitute the Board of Directors of the Company
                      (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 (i), (iii) or (iv) of this Section
                      V.A.3) whose election by the Board or nomination for
                      election by the Company's stockholders was approved by a

                      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

                               (iii) the stockholders of the Company approve 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

                      plan of complete liquidation of the Company; or

                      disposition by the Company of all or substantially all of
                      the Company's assets.

              4.      The "Company" means UST Corp. or, following a Change of
                      Control, any successor of UST Corp.


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, excluding only
              such administrative changes as may be required for the assumption
              of this Plan by the successor of Company upon a Change of
              Control, and any participating employee who is such for purposes
              of this Plan at the





                                      -5-
<PAGE>   6
              time of a Change of Control will remain so for twelve (12) months
              following that Change of Control.

         C.   If you believe you are being denied any rights under the Plan,
              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.

         D.   As a participant in the Plan, you are entitled to certain rights
              and protections under ERISA.  ERISA provides that all Plan
              participants shall be entitled to:

              1.      examine, without charge, at the Plan administrator's
                      office, all Plan documents and copies of the documents
                      filed by the Plan administrator with the U.S. Department
                      of Labor; and

              2.      obtain copies of these documents and other Plan
                      information upon written request to the Plan
                      administrator.  The Plan administrator may make a
                      reasonable charge for the copies.

              In addition to creating rights for Plan participants, ERISA
              imposes duties upon the people who are responsible for the
              operation of the Plan.  The people who operate the Plan, called
              "fiduciaries", have a duty to do so prudently and in the interest
              of Plan participants.

<PAGE>   7
              Neither the Company nor any other person may discriminate against
              an employee in any way to prevent him/her from obtaining benefits
              or exercising rights under ERISA.

              If a claim for benefits is denied in whole or in part, you must
              receive a written explanation of the reason for the denial.  You
              have the right to have the Plan administrator review and
              reconsider the claim.

              Under ERISA, there are steps you can take to enforce the above
              rights.  For instance, if you request materials from the Plan
              administrator and you do not receive them within 30 days, a suit
              may be filed in federal court.

              In such a case, the court may require the Plan administrator to
              provide the materials and pay you up to $100 a day until they are
              received, unless they were not sent due to reasons beyond the
              Plan administrator's control.  If you have a claim for benefits
              which is denied or not processed, in whole or in part, a suit may
              be pursued in a state or federal court.  If you are discriminated
              against for asserting your rights, you may seek assistance from
              the U.S.  Department of Labor, or may file suit in a federal
              court.

              The court will decide who should pay the court costs and legal
              fees.  If you are successful, the court may order the other party
              to pay these costs and fees.  If you should lose, the court may
              order you to pay these costs and fees.

              If you have any questions about the Plan, you should contact the
              Plan administrator.  If there are any questions about this
              statement or about employee rights under ERISA, please contact
              the nearest area office of Pension and Welfare Benefits, U.S.
              Department of Labor.

         E.   The following information about this Plan is provided in
              accordance with the applicable requirements of ERISA and the
              regulations promulgated thereunder:

                                JANUARY 1, 1995


I.       PURPOSE

         This Plan is intended to provide salary continuation to certain
designated Senior Officers of UST Corp. (the "Company") in the event that their
employment is terminated as provided hereafter due to a reduction in force or a
corporate restructuring or following a Change of Control.


II.      ELIGIBILITY TO PARTICIPATE

         A.   In order to be eligible to participate in this Plan, you must be
              currently designated, in writing, by the Chief Executive Officer
              of the Company or his designee as a "Senior Officer" for purposes
              of this Plan.

III.     QUALIFYING EVENTS

         A.   An employee eligible to participate in this Plan under Section II
              above (a "participating employee") is entitled to receive
              benefits 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 reinstatement, at the time his/her
              employment terminates; and (ii) 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 of 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;





<PAGE>   2


         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

         A.   The following are examples of events in which an employee would
              not qualify for benefits under this Plan:

                      his/her 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, as determined by
                      the Company; 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.

                      employee has completed less than five (5) full years of
                      service with the Company as of the date employment
                      terminates; or

              2.      Thirty-nine (39) weeks pay, at the participating

              3.      In the case of any participating employee employed on a
                      part-time basis, benefits hereunder shall be pro- rated,
                      based on the number of hours the employee is regularly
                      scheduled to work per week.

         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 health 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 the Company and their eligible dependents
              generally immediately prior to such Change of Control, if
              greater.

         C.   For purposes of determining the length of service of a
              participating 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 (B) 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.

              and all payments to be provided hereunder to or on behalf of any

              directives of federal, state and other governmental and

                      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

                      the Company's assets.

              4.      The "Company" means UST Corp. or, following a Change of
                      Control, any successor of UST Corp.


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





                                      -5-
<PAGE>   6


              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, excluding only
              such administrative changes as may be required for the assumption
              of this Plan by the successor of the Company upon 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 Plan,
              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.

                                                              EXHIBIT 10(y)(i)


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

         AGREEMENT made as of February 14, 1995 and effective January 1, 1995
between United States Trust Company ("USTC"), a banking and trust company
having its principal place of business in Boston, Massachusetts, and joined in
as to certain matters by UST Corp. ("UST"), a Massachusetts corporation also
having its principal place of business in Boston, Massachusetts and the parent
of USTC; and Domenic Colasacco (the "Employee").

                                  BACKGROUND
                                  ----------

         The Employee and the other principals of the Asset Management Division
of USTC ("AM") listed on Schedule I hereto and such other principals as may be
added pursuant to the Unifying Agreement (as hereinafter defined) (all such
employees, while they remain principals, being referred to herein from time to
time as "Employee/Principals") are concerned that previous UST and USTC
practices have not allowed for enough spending to generate growth in AM's
business, or for fully competitive compensation for its principals; want
assurances of continued freedom to manage the AM business; want to participate
in an incentive compensation program which reflects the value created in this
business; and want to make it attractive to any potential acquirer of UST, USTC
or AM to (i) protect existing relationships with AM employees and clients, (ii)
avoid re-writing existing client contracts, and (iii) further AM as a separate
business conducted under the name "United States Trust Company".

         UST and USTC want to stabilize and increase the profitability of AM;
pay competitive compensation; provide incentive compensation reflecting the
growth in the business of AM; and (in the event of a "Triggering Event" as
hereinafter defined) offer an opportunity to a prospective purchaser to retain
the services of Employee and the other Employee/Principals and thereby receive
a continuing stream of profits from AM.

         UST and USTC recognize the importance of Employee to their business
and to USTC's ability to retain AM client relationships, and desire that USTC
employ Employee as an officer and principal of AM for the period of employment
and upon and subject to the terms herein provided.

         UST and USTC wish to be assured that Employee will not compete with
AM's business during the period of employment, and in certain circumstances and
as set forth below will not for a period thereafter solicit any Past, Present,
or Potential Clients (as hereinafter defined) of AM and will not by such
solicitation damage USTC's and AM's goodwill among its clients and the general
public.

                                      1
<PAGE>   2
         Employee desires to be employed by USTC and serve as an
Employee/Principal of AM and to participate in the incentive compensation
program contemplated by this agreement, and to refrain from competing with USTC
or AM or soliciting AM's clients for the periods and upon and subject to the
terms herein provided.

         Employee has been employed by USTC and AM for approximately 21 years;
has while so employed contributed to the acquisition and retention of AM's
clients, and will continue to seek to acquire and retain clients and to
generate goodwill for AM in the future as an officer and employee of USTC and
an Employee/Principal of AM for the periods and on the terms contemplated
hereby.

         When the terms "AM," "AM's business," or the "AM Division" are used
herein, such terms specifically exclude the non- investment advisory business
of USTC such as (1) the business of UST Capital Corp. (venture capital) and (2)
the management of USTC's internal securities portfolio.  Such terms, however,
include the investment return on allocated, but unexpended, portions of AM's
Share of Revenues as reflected on Schedule V. The investment return on
allocated, but unexpended, portions of AM's share of revenues shall be measured
at the end of each calendar quarter by multiplying the average of the month end
balances during such quarter by the published thirteen week U.S. Treasury Bill
Rate at the end of such calendar quarter and such interest income shall be
added to "AM's Share of Revenues".  All current Employee/Principals are listed
on Schedule I.

         Employee, the other Employee/Principals, UST and USTC have entered
into an agreement of even date herewith (the "Unifying Agreement") which
describes generally their agreements and certain procedures they have agreed to
follow among themselves.  This Employment Agreement is executed pursuant to and
in accordance with the terms of the Unifying Agreement.  Certain capitalized
terms used but not defined herein shall have the meanings given them in the
Unifying Agreement.

                                  AGREEMENTS
                                  ----------

         In consideration of the premises, the mutual covenants and the
agreements hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
covenant and agree as follows:

         SECTION 1.  ORIGINAL TERM OF EMPLOYMENT; COMPENSATION.  USTC agrees 
to employ Employee for a period of two and one-half (2 1/2) years beginning 
on the date hereof (the "Original Term") as an officer of USTC and an
Employee/Principal of AM; and Employee hereby accepts such employment.  USTC
will pay Employee for Employee's services during the Original Term, and any
Renewal Term (as hereinafter provided) and any Phase II Term, the Annual Base
Salary set forth on Schedule I hereto, and such additional annual incentive
payments as shall be determined by the


                                      2
<PAGE>   3
Employee/Principals consistent with the Revenue Sharing Provision (Section 10
hereof),  and subject to such payroll and withholding deductions as are
required by law.  Consistent with the Revenue Sharing Provision, the Employee's
total compensation will be reviewed at least annually in accordance with the
Unifying Agreement, having in mind that such compensation be fair and
reasonable in light of Employee's position and the duties to be performed by
the Employee and the Employee's efforts to enhance the business of AM.

         SECTION 2.  RENEWAL TERMS.  If no "Triggering Event" has occurred
and this Agreement has not been terminated by either party (all as hereinafter
provided) prior to the end of the Original Term, then the Original Term shall
be automatically extended for successive six month renewal terms (each referred
to herein as a "Renewal Term", or collectively as "Renewal Terms") until such
Triggering Event or termination has occurred, or until the Employee shall have
provided at least six months advance written notice to UST and USTC of election
not to enter a Renewal Term.

         SECTION 3.  NOTICE OF TERMINATION OF ORIGINAL TERM BY EMPLOYEE.
On or before the last day of the second year of the Original Term and assuming
that this Agreement has not been earlier terminated or entered upon the Phase
II Term (all as hereinafter provided), the Employee may give written notice to
UST and USTC of termination, whereupon all the provisions of this Agreement
will terminate (except as noted below in this Section 3) on the last day of the
Original Term.  If there has been a material breach of this Agreement by
Employee at any time during the Original Term or any Renewal Term, and the
arbitration under Section 18 hereof has confirmed that a material breach has
been committed by the Employee and such breach is uncured during the applicable
grace period, then the Employee will be subject in full to all of the
restrictions of Section 12, 13 and 14 hereof for the remainder of the
applicable term plus 90 days.  However, should the Employee terminate this
Agreement without a material breach at the end of the Original Term or at the
end of any Renewal Term, Sections 12, 13 and 14 of this Agreement shall not
apply.  Notwithstanding the foregoing, should the Employee terminate this
Agreement as described in either of the immediately preceding two sentences,
UST and USTC will retain all of their respective common law rights against the
Employee with respect to confidentiality, protection of customer lists, trade
secrets, non-competition and similar matters.

         SECTION 4.  PHASE II TERM.  If a Triggering Event occurs during
the Original or a Renewal Term, any such term shall automatically terminate and
the Phase II Term shall commence as of the earlier of the date of signing of a
definitive merger or acquisition agreement or the date of occurrence of such
Triggering Event.  The Phase II Term shall be for a period of three years from
the Closing Date under such definitive merger, consolidation or acquisition
agreement, or the date of the agreement related to any other such Triggering
Event, but in no event for longer than four years from such signing date, and
shall be terminable in the same manner as the Original


                                      3
<PAGE>   4
Term under Section 3 above (the "Phase II Term"). The "Closing Date" shall mean
the date on which the merger or consolidation becomes effective, the
acquisition is consummated or the change in corporate ownership related to any
other such Triggering Event takes effect. If the revenues of the AM business
decline precipitously and the Formula Payment described in Section 11 below
would be less than $3 Million, then the Employee may decline to accept the
Formula Payment and the Phase II Term.  If the AM revenues likewise decline,
and the Formula Payment described in  Section 11 below would be less than $5
Million, the Employee/Principal may elect to reduce the Phase II Term by one
year.

         SECTION 5.  TERMINATION BY EMPLOYEE FOR BREACH OF "INDEPENDENCE
ASSURANCES."  In the event of the material breach by UST or USTC (or their
respective successors) of any one or more of the "Independence Assurances"
listed below, the Employee/Principals, acting in accordance with the Unifying
Agreement, shall have the right (subject to compliance with Section 18 hereof)
but not the obligation, upon 30 days prior written notice to UST and USTC, to
terminate this Agreement.

         (a)     "Independence Assurances" shall consist of UST's and USTC's
non-interference (unless requested by the Employee/Principals of AM acting in
accordance with the Unifying Agreement) in the following:

                 (i)  The Employee/Principals control of AM's investment
philosophy and investment approach, business strategy, conduct of investment
analysis, portfolio selection, marketing, client retention and acceptance of
new clients, and client service;

                 (ii)  Authority of the Employee/Principals to hire and fire AM
personnel within the scope of UST's "Policies" (as hereinafter defined) and
applicable Federal and Massachusetts laws, subject to UST's right to approve
any person chosen by the Employee/Principals as the Senior Principal of AM,
which person shall also serve initially (i) as the Chief Executive Officer of
USTC, and (ii) on USTC Board of Directors.  UST, as sole shareholder of USTC,
subject to the terms of the Unifying Agreement and this Agreement, will at all
times retain the right to select a Chief Executive Officer of USTC who is not
an employee of AM.  USTC will not, however, select the Senior Principal;

                 (iii)  The Employee/Principals' authority to set AM client
fees based on their judgment concerning the market for services rendered by AM;

                 (iv)  The Employee/Principals' authority to establish AM's
operating expense budget and compensation practices, limited by "AM's Share of
Revenues" as provided in Section 10 (See Schedule V for example); and limited
further with respect to total cumulative cash incentive compensation for
Employee/Principals in the aggregate accrued in each of the years ending
December 31, 1994 and December 31, 1995, to $1.3 million plus incentive
compensation accrued in 1993 (it being understood





                                       4
<PAGE>   5
that the Formula Payment is not to be regarded as cash incentive compensation
for any purposes);

                 (v)  The Employee/Principals' authority to add and delete
Employee/Principals of AM in accordance with the Unifying Agreement; and

                 (vi)  The recognition by UST and USTC that AM, in pursuit
of its "socially-sensitive" investment objectives, may take some public
positions which may not represent the views of UST or USTC management.  The
Employee, however, recognizes that Employee's actions will remain subject to
the provisions of the Code of Ethics, Employment Policies, and certain other
key corporate policies of UST and USTC listed on and attached to Schedule II
hereto ("Policies"), as revised from time to time on a company-wide basis in
the ordinary course of UST's and USTC's business (which revisions shall be made
available to Employee at UST's principal office in Boston); and applicable
Federal and Massachusetts laws, regulations, policies, orders or understandings
in use by or applicable to UST and USTC.

         (b)     In the event that any of the "Independence Assurances" have
been materially breached and not cured pursuant to Section 18, the Employee
may act either individually or in concert with any other Employee/Principal or
Employee/Principals or other employees so as to constitute a "person" as
defined in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the
"Exchange Act"), in electing to terminate their Employment Agreements, e.g.
they may collectively decide to give five (5) days notice and leave USTC to
form a new business which may directly compete with AM's business and Sections
12, 13 and 14 of this Agreement will not apply.

         SECTION 5A.  OVERSIGHT FUNCTION OF USTC'S BOARD OF DIRECTORS.
USTC's Board of Directors (a majority of whom shall not be Employee/Principals)
shall continue to exercise its oversight function of the business activities of
AM.  In performing such oversight function, USTC's Board the Directors will
assure itself that AM's business and operations are being conducted in a manner
consistent with applicable law and regulations, and such Board will be expected
to meet its fiduciary responsibilities to USTC and its depositors, and to UST,
in all respects, including without limitation, the prevention of corporate
waste of assets and taking steps to see that AM's business is operated with
their respective best interests in mind.  If in performing such oversight
function, the Board causes UST or USTC to breach an Independence Assurance and
such breach is (a) confirmed by the arbitrator under Section 18 or not
contested by UST or USTC and (b) not cured within the applicable grace period,
the Employee may terminate this Agreement and the Employee will leave with the
rights described in Section 5(b) of this Agreement.

         SECTION 6.  MATTERS NOT CONSTITUTING "INDEPENDENCE ASSURANCES".
The following shall specifically not be considered as "Independence Assurances"
but shall nevertheless govern the relationship by and among UST, USTC and AM:


                                      5
<PAGE>   6

         (a)     The location of AM's business for a period of three years from
January 1, 1995 on two floors at 40 Court Street, Boston, MA.  The Employee and
the other Employee/Principals shall cause AM to give twelve months written
notice of termination of such occupancy, if they so elect, no earlier than
December 31, 1996.  "Fair Rental" shall be charged or allocated by UST or USTC
for AM's premises, and UST or USTC shall give AM "high priority" with respect
to remodeling and upgrading of space.

         (b)     Matters covered in a Memorandum dated September 14, 1994 on
"Capital Expenditures/Intercompany Charges" which is attached as Schedule VI
hereto.

         (c)     The taking of reasonable steps by the Employee and the other
Employee/Principals to cause that appropriate levels of profit from AM's
business to be reinvested in the business (infrastructure, systems, facilities,
product development, compensation to staff members who are not Principals,
additional staff) during the Total Term (as hereinafter defined).  For the year
1995, the amount considered "appropriate" would be the investment of
approximately five percent (5%) of "Base Annual Revenues of AM" as defined in
Section 10.

         (d)     The amortization of AM capital expenditures over a period in
accordance with UST's and USTC's then current policy to the extent it is
consistent with GAAP.  In connection with the foregoing capital expenditures,
at the reasonable request of AM funding will be provided by UST and/or USTC
which will charge AM a fair interest rate for the cost of capital employed.
(See also Schedule VI).

         (e)     The providing of such information as is reasonably necessary
for UST to manage its affairs and responsibilities subject to client
confidentiality, including but not limited to information necessary to comply
with generally accepted accounting principles ("GAAP") in the preparation of
financial statements, budgets and profit plans, and for shareholder
communications, and responses to regulatory requests.

         (f)     The actions of all Employee Principals shall remain subject,
without limitation, to the terms of UST's Code of Ethics, the Payment Approval
Policy and the other Policies set forth in Schedule II hereto.

         SECTION 7.    TERMINATION OF EMPLOYMENT BY USTC.

         (a)     Employee's employment may be terminated by USTC (by majority
vote of its Board of Directors) in the following circumstances:

                 At any time after due notice and reasonable opportunity to
                 correct such conduct, (i) in the event of Employee's material
                 breach of any of the terms of this Employment Agreement; (ii)
                 in the event of Employee





                                       6
<PAGE>   7
                 causing a material breach of any of the other
                 Employee/Principals' duties to UST and USTC under Section 10
                 (Revenue Sharing Provision ); (iii) in the event of Employee's
                 willful misconduct in the performance of the Employee's duties
                 hereunder including, without limitation, but subject to
                 Sections 5 and 6 hereof, Employee's willful refusal to carry
                 out any "proper direction" by USTC's Board of Directors with
                 respect to the services to be rendered by Employee hereunder
                 or the manner of rendering such services; or (iv) in the event
                 of Employee's conviction of a crime involving moral turpitude.
                 The term "proper direction" as used in clause (iii) above, may
                 not be used in connection with an instruction, direction or
                 order which would cause UST or USTC to violate an
                 "Independence Assurance".

         (b)     In the event of Employee's death during the term of
employment,  unless otherwise determined by the Employee/Principals acting
pursuant to the Unifying Agreement, USTC's and UST's obligations to pay further
compensation hereunder shall cease as of the date of death, except that any
amounts due under Section 11 hereof or otherwise owed to Employee under welfare
or benefit plans or for deferred compensation and any amounts heretofore
accrued under Sections 3.1 and 3.2 of the Unifying Agreement, shall be paid
when due to the Employee's estate or named beneficiary.

         SECTION 8.   Office and Duties.  During the Original Term, any
Renewal Term, and the Phase II Term, if any, (hereinafter the "Total Term"),
Employee shall hold such positions and perform such duties relating to AM's
business and operations as are described on Schedule I hereto, and as may
otherwise from time to time be assigned to Employee by the Employee/Principals
consistent with all of the terms of this Agreement.  During the Total Term and
while employed by USTC, Employee shall devote (except as noted on Schedule I)
substantially all of Employee's business time to the Employee's duties
hereunder and shall, to the best of Employee's ability, perform such duties in
a manner which will faithfully and diligently further the business and
interests of AM.

         At any time while employed by USTC, Employee shall not directly or
indirectly solicit the business of any Past, Present, or Potential Clients (as
hereinafter defined) except on behalf and for the benefit of AM, or pursue any
other business activity, including, without limitation, serving as an officer,
director, employee, or adviser to any business entity other than AM, without
UST's and USTC's prior written consent; provided, however, that Employee may
without such consent, render without compensation investment advisory services
to immediate members of Employee's family, which shall include the Employee and
any trust or account which is comprised entirely of assets held for the benefit
of such Employee and/or immediate members of Employee's family, and may be
involved in such additional activities without such consent as are listed on
the Schedule I hereto.  Employee agrees to travel to whatever





                                       7
<PAGE>   8
extent is reasonably necessary in the conduct of AM's business.  Except when
engaged in such travel, Employee's place of employment shall be in the greater
Boston area of Massachusetts unless otherwise agreed to by Employee, UST and
USTC, and the Employee/Principals acting in accordance with the Unifying
Agreement.

         The term "Past Client" shall mean at any particular time any person or
entity who within three years prior to such time had been but at such time is
not an advisee, investment advisory customer, or client of AM.

         The term "Present Client" shall mean at any particular time any person
or entity who is at such time an advisee, investment advisory customer, or
client of AM.

         The term "Potential Client" shall mean at any particular time any
person or entity to whom AM, through any of the Employee/Principals or other of
its employees, has within three years prior to such time offered (by means of a
personal meeting, telephone call, or a letter or a written proposal
specifically directed to the particular person or entity) to serve as
investment adviser but who is not at such time an advisee or investment
advisory customer or client of AM.  The preceding sentence is meant to exclude
form letters and blanket mailings.

         The terms "Client" or "Client List" when used herein shall mean all
Past, Present, and Potential Clients as heretofore defined.  The term "Client"
when used in this Employment Agreement with respect to wrap accounts, shall
mean the wrap sponsors and the brokers employed by such wrap sponsors but not
the underlying wrap account holders.

         SECTION 9.    BENEFITS.  Employee shall participate, to the extent
Employee is eligible and in a manner and to an extent that is fair and
appropriate in light of the position and duties granted to Employee hereunder,
in all pension, profit-sharing, group insurance, or other fringe benefit plans
(other than UST corporate stock compensation plans) which UST or USTC may
hereafter in their absolute discretion make available generally to employees of
AM, but neither UST nor USTC will be required to establish any such program or
plan.  Employee shall be entitled to such vacations and to reimbursement of
such expenses as UST's or USTC's policies allow to all employees having
comparable responsibilities and duties.  So long as such additional benefits
are payable out of or accrue to "AM's Share of Revenues" as hereinafter
defined, the Employee/Principals may provide additional executive benefits to
themselves in addition to those provided by UST, provided that no such benefit
be qualified under Section 401 of  the Internal Revenue Code or non-qualified
(under Section 401 of the Internal Revenue Code) pursuant to the terms of a
plan or arrangement which operates in a manner that is substantially similar or
mirrors a qualified plan, and provided further that the award of any such
benefits does not increase the cost to UST of providing benefits to UST
employees who are not employees of AM.





                                       8

         SECTION 10.    REVENUE SHARING PROVISION.  The purpose of this
Revenue Sharing Provision is to provide UST with an acceptable stream of income
and to permit AM to retain a specified percentage of its revenues for use by
Employee/Principals, including the Employee, in their discretion in paying
expenses of operation, including compensation.  It is intended to allow the
Employee and the other Employee/Principals to be compensated for enhancing and
growing AM's revenues in a substantial manner and to make operating decisions
freely within the limits of "AM's Share of Revenues," as such term is defined
below.  See Schedule V for examples of Revenue Sharing calculations.

         (a)     ALLOCATION OF REVENUES.  "Base Annual Revenues of AM" in 1994
and all subsequent years for purposes of this Revenue Sharing Provision shall
be AM's actual 1994 Revenues less $750,000, such total amount to be
appropriately modified to reflect changes in the United States Bureau of Labor
Statistics Cost of Living Index for the Boston Metropolitan Statistical Area or
any designated successor index for 1995 and all subsequent years.  The term
"Revenues" shall mean AM's revenues calculated on an accrual basis in
accordance with GAAP, (excluding shared revenues paid to investment or other
firms or professionals and generated from AM clients), consistent with USTC's
usual practice.

         During the pro-rated six month period commencing July 1, 1994 and
         ending December 31, 1994, and for each calendar year and for portions
         thereof on a pro-rated basis thereafter, AM shall retain sixty percent
         (60%) ("Base AM Retention"), of AM's pro-rated actual Revenues and AM
         shall make available to USTC for distribution to UST forty percent
         (40%) ("Base UST Amount"), subject to adjustment as set forth in this
         Section 10(a).

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar of AM's annual revenues
         over Base Annual Revenues of AM, AM shall retain an additional $.40,
         and an additional $.60 shall be allocated to UST, provided that in no
         event shall UST's Share of Revenues exceed fifty percent (50%) of
         actual Annual Revenues of AM.

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar that actual Annual
         Revenues of AM are less than Base Annual Revenues of AM, Base AM
         Retention shall be reduced by $.40 and the Base UST Amount shall be
         reduced by $.60, provided that in no event shall  UST's Share of
         Revenues be less than thirty percent (30%) of Annual Revenues of AM.

         Amounts retained by AM as aforesaid are herein referred to as "AM's
Share of Revenues".  Amounts allocated to UST as aforesaid are herein referred
to as "UST's Share of Revenues".





                                       9
<PAGE>   10
         (b)     FLOOR INCENTIVE.  In addition, during the Original Term of
this Agreement (thirty months), AM shall retain a "Floor Incentive" of $40,000
per month from "UST's Share of Revenues" ($1.2 million in the aggregate).  The
"Floor Incentive" shall be accrued by USTC and paid pursuant to subsection
(d)(iv) hereof, and shall be excluded from the limitations of Section 5(a)(iv)
of this Agreement.  In the event of a material breach by UST or USTC of this
Agreement during the Original Term (which breach is not cured during the
applicable grace period and is either confirmed by the arbitrator under Section
18 hereof or not contested by UST or USTC), the Employee/Principals (for
distribution in accordance with the Unifying Agreement) may elect to receive an
aggregate lump-sum payment determined by multiplying (x) the monthly "Floor
Incentive" by (y) the remaining months in the Original Term.  If a "Triggering
Event" occurs during the period January 1, 1995 through June 30, 1998, the
aggregate Floor Incentive, net of tax, accrued during the four full calendar
quarters next preceding the date of the Triggering Event, shall not be deducted
from "AM's After Tax Revenues" for purposes of calculating the Section 11
Formula Payment.  Moreover, if a Triggering Event occurred before all Floor
Incentives have been paid, UST or USTC's successor shall assume responsibility
to make the remaining Floor Incentive payments.

         (c)     SPECIAL PROVISIONS.  It is understood and agreed that:

                 (i)      The balance of "Base AM Retention" for the period
                          July 1, 1994 through December 31, 1994 shall be paid
                          by UST or USTC to AM no later than February 15, 1995.

                 (ii)     All amounts due to Robert B. Zevin pursuant to his
                          agreement dated September 30, 1994 with USTC shall be
                          considered as expenses to come out of "AM's Share of
                          Revenues" in each year in accordance with the
                          Unifying Agreement.

                 (iii)    The application of this Section may make it
                          unattractive for AM to enter a business activity with
                          a profit margin of less then 40%.  Accordingly, the
                          parties have agreed to negotiate separate "side
                          letters" with respect to revenue sharing on any new,
                          lower-margin business opportunities identified in the
                          future by AM and regarded as worthy of pursuit by UST
                          and/or USTC.

                 (iv)     The parties hereto further understand and acknowledge
                          that the term "Revenues" as used herein is intended
                          to cover revenues of AM as they now exist and as they
                          may grow or contract internally, and not revenues
                          from the acquisition by UST or USTC of another
                          investment advisory firm concerning which the parties
                          hereto agree to negotiate in good faith as to revenue
                          sharing.

                 (v)      The investment return on allocated, but unexpended,
                          portions of AM's Share of Revenues shall be measured
                          at the end of each calendar quarter by multiplying
                          the average of the month end balances during such
                          quarter by the published thirteen week U.S. Treasury
                          Bill Rate at the end of such calendar quarter.This
                          interest income shall be added to "AM's Share of
                          Revenues".

         (d)     TRANSFER OF REVENUES TO UST; RETENTION OF REVENUES BY
                 USTC;COMPENSATION OF EMPLOYEE/PRINCIPALS.

                 (i)      The Employee/Principals and AM shall use AM's Share
                          of Revenues to pay and provide for AM's business
                          expenses and expenditures including, without
                          limitation, investment in AM's business and new
                          products (see Section 6(d) above) and salaries of its
                          employees, except that any federal, state or local
                          income tax to which USTC is subject shall be the
                          responsibility of UST and shall not be treated as a
                          business expense of AM.

                 (ii)     The Employee/Principals shall incur no expenses or
                          obligations on behalf of AM which exceed USTC's
                          ability to pay or provide for them when due out of
                          AM's Share of Revenues.  The Employee/Principals
                          shall not incur obligations or make binding
                          commitments on behalf of USTC or UST not related to
                          AM's business and requiring expenditures by USTC in
                          excess of $50,000, or make representations to third
                          parties that they have the authority to do so.
                          However, the Employee/Principals may represent and
                          advertise that AM is a division of USTC and an
                          affiliate of UST, and other than as limited above in
                          this Section 10 (d)(ii), may incur obligations or
                          make binding commitments on behalf of USTC in the
                          ordinary course of business.

                 (iii)    The Employee/Principals may (subject to Policies and
                          applicable laws and regulations) pay to AM's
                          employees, including the Employee and the other
                          Employee/Principals, at times and in amounts and
                          proportions determined in accordance with the
                          Unifying Agreement, the balance of AM's Share of
                          Revenues remaining after the payment of all of the
                          amounts required under subsection (d)(i) hereof and
                          subject to Section 5(a)(iv).

                  (iv)    The Employee's Revenue Sharing compensation out of
                          "AM's Share of Revenues" shall be allocated in
                          accordance with the terms of the Unifying Agreement.
                          The Employee/Principals have provided to UST and USTC
                          in the Unifying Agreement their procedures for
                          determining changes, if any, in the allocation of





                                       11
<PAGE>   12
                          Revenues among the Employee/Principals.  If an
                          Employee/Principal chooses to leave USTC's employ
                          after bypassing this change determination mechanism
                          or refusing to abide by its results, the
                          Employee/Principal shall be deemed to have committed
                          a material breach of this Employment Agreement.

                 (v)      The Employee/Principals and AM shall make available
                          to UST, UST's Share of Revenues upon reasonable
                          request by UST and action by USTC's Board of
                          Directors.  The Employee/Principals shall not spend
                          or incur obligations to spend any part of UST's Share
                          of Revenues.

         (e)     ADMINISTRATION.  The parties hereto and the other
Employee/Principals agree to meet and consult to endeavor in good faith to
agree on appropriate procedures, in addition to Policies and applicable laws
and regulations,  for administering the provisions of this Section 10.

         The Employee/Principals shall retain control over all expenditures of
AM, subject to the power of USTC's Board of Directors to exercise its rights
under Section 5A, and subject to this Revenue Sharing Provision, and
recognizing that AM is a division of USTC.

         (f)     TERM AND STATUS AS PARTIES.  This Revenue Sharing Provision
shall continue in effect until terminated by agreement of UST, USTC, and the
Employee/Principals acting in accordance with the Unifying Agreement.  If the
employment of Employee by USTC ceases other than as a result of a material
breach by UST or USTC of this Employment Agreement, such Employee shall
thereupon automatically cease to be a party to this Revenue Sharing Provision
and to have any rights or obligations under this Section, and shall cease to be
an Employee/Principal for the purposes of this Provision.  Nothing  in this
Employment Agreement shall be construed to grant to the Employee any right to
be employed by USTC beyond the terms of this Employment Agreement.

         SECTION 11.   FORMULA PAYMENT.  If Employee is still employed by
USTC at the time of a "Triggering Event" (as hereinafter defined), the Employee
shall receive Employee's share of a formula payment (the "Formula Payment") as
follows:

         (a)     Unless otherwise agreed by the Employee/Principals acting in
accordance with the Unifying Agreement, the Employee's share of the Formula
Payment shall be the percentage set forth after the Employee's name on Schedule
III hereto;

         (b)     The "Formula Payment" shall be 3.33 times "AM's After Tax
Revenues" (as hereinafter defined and meaning generally UST's Share of Revenues
minus taxes);





                                       12
<PAGE>   13
         (c)     "AM's After Tax Revenues" shall be the portion of AM's
after-tax Revenues contributed, accruing or allocated to UST for the four full
calendar quarters next preceding the date of the Triggering Event; determined
in accordance with GAAP consistently applied in such periods.  For purposes of
this Subsection, there shall be assumed a combined federal and state tax rate
of 38%, such rate to be appropriately adjusted to reflect changes in applicable
federal and state corporate tax rates.  An example of this calculation is set
forth on Schedule V.

         (d)     The Formula Payment shall be adjusted in accordance with
Schedule IV hereto for gain or loss of AM clients between the signing of a
definitive merger, consolidation or acquisition agreement or an agreement
related to another Triggering Event and the Closing Date related to any such
Triggering Event.

         (e)
                 (i)      At the Closing Date of a Triggering Event, three Key
                          Employees shall be identified as follows.  For every
                          person who has been an Employee/Principal at any time
                          during the previous 15 months there shall be
                          calculated a Weighted Average Share equal to the sum
                          of (a) the share of the Formula Payment such person
                          was entitled to receive from time-to-time during the
                          preceding 15 months in accordance with Schedule III
                          and subsequent changes thereto by the
                          Employee/Principals acting in accordance with the
                          Unifying Agreement times (b) the number of days such
                          person was entitled to each such share.  The three
                          persons among those who are or have been
                          Employee/Principals on the Closing Date of the
                          Triggering Event or during the previous 15 months who
                          have the three highest Weighted Average Shares shall
                          be deemed the "Key Employees".

                 (ii)     If only one of the three Key Employees is no longer
                          in the employ of USTC as of the Closing Date of such
                          Triggering Event, then all of that Key Employee's
                          Weighted Average Share of the Formula Payment
                          (expressed by X%) shall be placed in escrow in the
                          manner contemplated by Section 11(f). To determine
                          the distribution of each of the three escrowed
                          installments use the following formula.  Revenues of
                          AM (as defined in Section 10(a)) for the last full
                          calendar year prior to a Triggering Event should then
                          be determined (the "Measuring Year").  Such Revenues
                          of AM for the Measuring Year multiplied by a decimal
                          representing 100% - X% equals the "Minimum Revenues".
                          If during the next full calendar year following the
                          Measuring Year, Revenues of AM are equal to or less
                          than Minimum Revenues none of the one-third of the
                          escrowed amount for such year will be paid to the
                          remaining Employee/Principals in accordance with this
                          Section and all of it will be retained by UST's or
                          USTC's successor.  If Revenues of AM for





                                      13
<PAGE>   14
                          that calendar year exceed Minimum Revenues, (i) take
                          the U.S. Dollar amount of such excess above the
                          Minimum Revenues and divide it by the Revenues of AM
                          for the Measuring Year minus the Minimum Revenues,
                          (ii) then multiply the resulting fraction by
                          one-third of the full escrowed amount, (iii) the
                          product of the foregoing formula should be delivered
                          to the remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and the remainder of that installment
                          should be retained by UST or UST's successor.
                          Similar calculations should be made for the second
                          and third installments, but in each case using the
                          same Minimum Revenues.

                 (iii)    If two or more of the Key Employees are no longer in
                          the employ of USTC as of the Closing Date of such
                          Triggering Event, then 100% of the Formula Payment
                          shall be placed in escrow in the manner contemplated
                          by Section 11(f).  To determine the distribution of
                          each of the three escrowed installments use the
                          following formula.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment equal or exceed
                          Revenues of AM for the Measuring Year, all of that
                          escrowed installment should be distributed to the
                          remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and none should be retained by UST or
                          USTC's successor.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment are less than
                          Revenues of AM for the Measuring Year, divide the
                          U.S. Dollar amount of Revenues of AM for such last
                          full calendar year by the U.S. Dollar amount of
                          Revenues of AM for the Measuring Year and multiply
                          the resulting fraction by one-third of the full
                          escrowed amount.  The product of the foregoing
                          calculation should be delivered to the remaining
                          Employee/Principals as a group for distribution in
                          accordance with the Unifying Agreement and the
                          remainder should be retained by UST's or USTC's
                          successor.

         (f)     Seventy percent (70%) of the Employee's share of the Formula
Payment shall be paid in cash within twenty (20) days of the Closing Date of
the Triggering Event.  The remaining thirty percent (30%) shall be placed in
escrow with an escrow agent acceptable to both UST and Employee/Principals and
paid to the Employee or the Employee's estate as provided in Section 7(b) in
installments of one third of the escrowed amount at the end of years one, two
and three (which may not be calendar years) after the Closing Date of the
Triggering Event plus interest, at the interest rates on the date of the
Closing Date of the Triggering Event of one, two and three year Treasury
securities,  provided that at the time of each such installment payment, the
Employee has not been terminated with cause or for a material breach or has not
voluntarily ceased to be employed by AM.

         (g)     A "Triggering Event" shall be deemed to have occurred when:

                 (i)      there occurs the signing of a definitive agreement of
                          merger or consolidation of UST or USTC with any other
                          corporation, other than a merger or consolidation
                          which would result in the voting securities of UST or
                          USTC 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 USTC, or such surviving entity outstanding
                          immediately after such merger or consolidation;
                          provided, however, that a merger or consolidation
                          effected to implement a recapitalization,
                          reorganization or restructuring of UST or USTC (or
                          similar transaction) in which no "person" (as defined
                          in (g)(iii) below) acquires more than fifty percent
                          (50%) of the combined voting power of UST's then
                          outstanding securities shall not constitute a
                          Triggering Event; or

                 (ii)     there occurs a closing of a sale or other disposition
                          by UST of more than 50% of UST's, USTC's or AM's
                          business and assets; or

                 (iii)    any "person", as such term used in Section 13(d) and
                          14(d) of the Exchange Act other than UST or USTC or
                          any of their respective subsidiaries or affiliates or
                          any trustee or other fiduciary holding securities
                          under an employee benefit plan of either of them or
                          any of their subsidiaries or 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
                          50% percent or more of the combined voting power of
                          UST's or USTC's then outstanding securities.

         If (i) more than 50% of UST's then outstanding common stock or assets
are acquired by a "person" whose consolidated assets prior to the Triggering
Event were less than $4 billion or (ii) UST's business assets and operations
are consolidated with those of another bank or bank holding company and the
resulting entity has consolidated assets of $5.5 billion or less, a Triggering
Event shall be deemed to have occurred, but the length of the Phase II term of
employment of the Employee shall be increased automatically by one additional
year.

         (h)     If UST agrees to be acquired by an entity with a public image
so starkly negative that AM's affiliation with that entity would be reasonably
likely, by itself, to cause a loss of more than 25% of AM's gross revenues in
one year (unless the parties





                                      15
<PAGE>   16
mutually agree to the contrary), the Employee/Principals at their option acting
pursuant to the terms of the Unifying Agreement (and provided such right is
exercised within 30 days of the public announcement of such acquisition) will
be relieved of all of the Employee's obligations under the Phase II Term and no
Formula Payment will be made.

         (i)     The parties acknowledge that any such Formula Payment is
intended to compensate the Employee for: (i) the automatic extension of this
Agreement occurring by reason of a Triggering Event; (ii) the Phase II
Non-Competition covenants specified in Section 12; and (iii) the loss of
opportunity to make up for reduced rate of compensation which such Employee
earned with USTC for periods prior to the effective date of this Agreement.

         SECTION 12.      PHASE II NON-COMPETITION COVENANTS.

         (a)     During the longer of the Phase II Term (as defined in Section
4) if Phase II shall commence while Employee is employed by USTC hereunder or
while Employee is employed by USTC during or after such Phase II Term
hereunder, Employee shall not, except in the course of his employment with
USTC, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, stockholder,
                          consultant, adviser, subsidiary, affiliate,
                          independent contractor or otherwise, investment
                          advisory services to any person or entity;

                 (ii)     Interfere with AM's relations with any person or
                          entity who at any time during such period was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person, other than by
                          discharge of such person as a part of Employee's
                          duties.

         (b)     Until one year following the end of the Phase II Term, if the
Phase II Term should commence while Employee is employed by USTC hereunder or
one year following the termination of Employee's employment with USTC during or
after such Phase II Term, Employee shall not, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, independent
                          contractor or otherwise, investment advisory services
                          to any person or entity who as of the date of the
                          termination or expiration of Employee's employment

<PAGE>   17
                          with USTC was or had been a Client (which means Past,
                          Present, and Potential Client);

                 (ii)     Interfere with AM's relations with any person or
                          entity who as of the date of the termination or
                          expiration of Employee's employment with USTC was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person.

         (c)     Notwithstanding the provisions of subsections (a)(i) and
(b)(i), the Employee may render without compensation investment advisory
services to any immediate member of Employee's family, which shall include the
Employee and any trust or account which is comprised entirely of assets held
for the benefit of such Employee and/or immediate members of such Employee's
family, and may engage in such other activities as are listed on Schedule I
hereto.

         (d)     Employee and USTC agree that the periods of time and the
unlimited geographic area applicable to the covenants of this Section 12 are
reasonable, in view of the receipt and expected receipt of the Employee's share
of Revenue Sharing as provided in Section 10(c), and other compensation, and
the Formula Payment provided herein; the geographic scope and nature of the
business in which AM is engaged; Employee's knowledge of AM's business; and
Employee's relationships with AM's investment advisory clients.  However, if
such period or such area should be adjudged unreasonable in any judicial
proceeding, then the period of time shall be reduced by such number of months
or such area shall be reduced by elimination of such portion of such area, or
both, as are deemed unreasonable, so that this covenant may be enforced in such
area and during such period of time as are adjudged to be reasonable.

         SECTION 13.      ALL BUSINESS TO BE THE PROPERTY OF USTC; ASSIGNMENT
OF INTELLECTUAL PROPERTY.  During the Phase II Term if Phase II shall commence
while Employee is Employed by USTC hereunder and thereafter while Employee is
employed by AM and/or USTC:

         (a)     Employee agrees that any and all presently existing investment
advisory business of AM and all business developed by Employee or any other
employee of AM, including without limitation all investment advisory contracts,
fees, commissions, compensation records, Client Lists (as defined in Section
8), agreements, and any other incident of any business developed or sought by
AM or earned or carried on by Employee for AM, are and shall be the exclusive
property of USTC for its sole use, and (where applicable) shall be payable
directly to USTC.





                                      17
<PAGE>   18
         (b)     Employee hereby grants to USTC (without any separate
remuneration or compensation other than that received by Employee from time to
time in the course of his or her employment) Employee's entire right, title,
and interest throughout the world in and to, all research, information, Client
Lists, and all other investment advisory, technical and research data made,
conceived, developed and/or acquired by Employee solely or jointly with others
during the period of Employee's employment by USTC, which relate to investment
advice as it was or is now rendered or as it may, from time to time, hereafter
be rendered or proposed to be rendered, but excluding such individual's ideas
and thought processes which are not embodied in written or machine readable
form (all such non-excluded items being referred to as "Intellectual
Property").

         SECTION 14.      CONFIDENTIALITY.  Except in performance of services
for USTC, Employee shall not, either during the Phase II Term if Phase II shall
commence while the Employee is employed by USTC hereunder or thereafter while
employed by AM and/or USTC, use for Employee's own benefit or disclose to or
use for the benefit of any person outside USTC, any information not lawfully
available to the public concerning any Intellectual Property, including Client
Lists, whether Employee has such information in his or her memory or embodied
in writing or other tangible form.  All such Intellectual Property and such
information concerning Intellectual Property, and all originals and copies of
any Intellectual Property, and any other written material relating to the
business of AM, shall be the sole property of USTC.  During such Term or
thereafter, upon the termination of Employee's employment in any manner or for
any reason, Employee shall promptly surrender to USTC all originals and copies
of any Intellectual Property, and Employee shall not thereafter use any
Intellectual Property.

         The foregoing notwithstanding, Employee will have no obligation to AM
or USTC with respect to the disclosure or use of any Intellectual Property or
information concerning Intellectual Property if:

         (a)  Such Intellectual Property or information is or becomes publicly
known or otherwise enters the public domain through no wrongful act of
Employee; or

         (b)  Such Intellectual Property or information is received from a
third party which has no obligation to UST or USTC to maintain it in
confidence.

         Notwithstanding the references to Client Lists above, it shall not be
a violation of this Section or Section 13 hereof for Employee to communicate or
do business with any Past, Present or Potential Client in the course of
Employee's employment with AM and USTC, and any such conduct shall be limited,
if at all, solely by Section 12 hereof.

         SECTION 16.      ASSIGNABILITY.  This Employment Agreement shall be
binding upon and inure to the benefit of UST, USTC, and to any person or firm
who may succeed to the business of UST, USTC, or AM.  This Employment Agreement
shall not be assignable by Employee, but it shall inure to the benefit of
Employee's heirs, executors, administrators and legal representatives.

         SECTION 17.      ENTIRE AGREEMENT.  This Employment Agreement and the
Unifying Agreement contain the entire agreement between USTC and Employee with
respect to the subject matter hereof, and supersede all prior oral and written
agreements between any of UST, USTC, AM and the Employee with respect to the
subject matter hereof, including without limitation any oral agreements
relating to compensation.

<PAGE>   20
         SECTION 18.      ARBITRATION.  In the event the parties hereto
disagree as to whether a material breach has occurred of: (i) the "Independence
Assurances" under Section 5; (ii) USTC's right of termination of Employee's
employment under Section 7; (iii) this Agreement by USTC as described in
Section 19 (b); (iv) the revenue sharing provisions of Section 10; or (v) the
formula payment provisions of Section 11, such dispute shall be settled by
arbitration before a single arbitrator to be then named by UST and a majority
of the Employee/Principals acting in accordance with the Unifying Agreement, in
Boston, Massachusetts in accordance with the Commercial Arbitration Rules of
the American Arbitration Association.  If such arbitrator cannot serve, then a
successor shall be appointed in accordance with such Rules.  If the arbitrator
finds that there has been a material breach (and such breach has not been cured
by UST or USTC within sixty (60) days of such finding or by Employee in
accordance with Section 7 hereof), then the remedies provided for in Section 19
shall become available, as appropriate.

         SECTION 19.      EQUITABLE RELIEF AND OTHER REMEDIES.

         (a)  Employee recognizes and agrees that UST's, USTC's or the
Employee/Principals' remedies at law for any breach of the provisions of
Sections 12, 13 and 14 hereof would be inadequate and that for breach of such
provisions UST, USTC and the Employee/Principals  shall, in addition to such
other remedies as may be available to any of them at law or in equity or as
provided in this Employment Agreement, be entitled to injunctive relief and to
enforce their respective rights by an action for specific performance to the
extent permitted by law, and to the right of set-off against any amounts due to
the Employee by UST, USTC or AM.  Should Employee engage in any activities
prohibited by this Employment Agreement, he or she agrees to pay over to USTC
or UST all compensation received in connection with such activities.  Such
payment shall not impair any other rights or remedies of UST, USTC or AM or
affect the obligations or liabilities of Employee under this Employment
Agreement or applicable law.

         (b)  Any termination by USTC of Employee's employment which is not
authorized by Section 7 hereof shall constitute a material breach of this
Agreement.  In the event of a material breach of this Agreement by UST or USTC
which is not cured pursuant to Section 18, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, USTC
shall pay Employee the Employee's then current Annual Base Salary for a period
equal to the greater of (i) twelve months or (b) the balance of the then
current term of this Agreement.  Any such payments shall not constitute part of
AM's Share of Revenues.  Should such a material breach occur and not be so
cured, the Employee shall be  free to compete, Sections 12, 13 and 14 shall not
apply and the Employee shall leave with the rights described in Section 5(b) of
this Agreement.

        (c)  Without limiting the generality of the foregoing, the parties 
expressly agree





                                      20
<PAGE>   21
that termination without cause of Employee's employment hereunder during the
Phase II Term by UST, USTC or any other person or entity will constitute a
material breach of this Agreement and, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, shall
give Employee the right to salary continuation as set forth in Section 19(b)
hereof.

         SECTION 20.      WAIVERS AND FURTHER AGREEMENTS.  Neither this
Employment Agreement nor any term or condition hereof, including without
limitation the terms and conditions of this Section 20, may be waived in whole
or in part as against UST, USTC, AM or Employee except by written instrument
executed by each of them, expressly stating that it is intended to operate as a
waiver of this Employment Agreement or the applicable term or condition hereof.
Each of the parties hereto agrees to execute all such further instruments and
documents and to take all such further action as the other party may reasonably
require in order to effectuate the terms and purposes of this Employment
Agreement as stated herein.  Furthermore, no waiver may violate the terms of
the Unifying Agreement and any waiver shall require action of the
Employee/Principals in accordance with the Unifying Agreement authorizing such
waiver.

         SECTION 21.      AMENDMENTS.  This Employment Agreement may not be
amended, nor shall any parties be added hereto, nor any change, modification,
consent, or discharge be effected except by written instrument executed by all
three of the Employee, USTC and UST.  Furthermore, no amendment or modification
may violate the terms of the Unifying Agreement and any amendment or
modification shall require action of the Employee/Principals in accordance with
the Unifying Agreement authorizing such amendment or modification.

         SECTION 22.      SEVERABILITY.  If any provision of this Employment
Agreement shall be held or deemed to be invalid, inoperative or unenforceable
in any jurisdiction or jurisdictions, because of conflicts with any
constitution, statute, rule or public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision in question
unenforceable in any other jurisdiction or in any other case or circumstance or
of rendering any other provisions herein contained unenforceable to the extent
that such other provisions are not themselves actually in conflict with such
constitution, statute or rule of public policy, but this Employment Agreement
shall be reformed and construed in any such jurisdiction or case as if such
invalid, inoperative, or unenforceable provision had never been contained
herein and such provision reformed so that it would be enforceable to the
maximum extent permitted in such jurisdiction or in such case.

         SECTION 23.      NO CONFLICTING OBLIGATIONS.  Employee represents and
warrants to USTC and UST that Employee has no other interest or obligation
which is inconsistent or in conflict with this Employment Agreement or which
would prevent, limit, or impair, in any way, Employee's performance of any of
the covenants or duties





                                      21
<PAGE>   22
hereinabove set forth.

         SECTION 24.      PARTIES.  It is understood and agreed that UST joins
in this Employment Agreement only as to such matters where its name appears
herein.  It is further understood and agreed that no person shall participate
in the benefits conferred on Employee/Principals by the terms of this and other
similar Employment Agreements unless such person has become a party to a
similar Employment Agreement or is described in Section 16.

         SECTION 25.      GOVERNING LAW.  This Employment Agreement shall be
governed by and construed and enforced in accordance with the laws of the
Commonwealth of Massachusetts which apply to contracts executed and performed
solely in Massachusetts.  UST, USTC and the Employee hereby consent to the
jurisdiction of any state or federal court located within Suffolk County,
Massachusetts, and assent that service of process may be made by registered
mail to the parties' respective addresses as provided in Section 15 hereof and
shall be effective in the same manner as notices are effective under such
Section 15.

         SECTION 26.      ACTION OF THE EMPLOYEE/PRINCIPALS.  Whenever the
Consent of the Employee/Principals shall be described herein, action by the
Employee/Principals or their duly authorized representative shall be required
in accordance with the Unifying Agreement, and such action shall be sufficient
hereunder.

         IN WITNESS WHEREOF, the parties have executed this Employment
Agreement as a sealed instrument as of the date first above written.

                                 Schedule IV
                        Adjustment in Formula Payment

In the event that USTC's assets under management diminish or increase between
the signing of a definitive merger or acquisition agreement or an agreement
related to another Triggering Event and the Closing Date related to such
Triggering Event, the Formula Payment otherwise calculated in accordance with
Section 11(b) shall be calculated as follows:

         (a)     The actual amount of AM's After Tax Revenues for the three
                 full calendar months preceding the Closing Date of the
                 Triggering Event shall be calculated and then multiplied by
                 four to determine an amount which shall be referred to herein
                 as "AM's Annualized After Tax Revenues".

         (b)     AM's Annualized After Tax Revenues shall then be divided by
                 AM's After Tax Revenues.  The resulting percentage (rounded to
                 the nearest one-hundredth of a percent) shall be referred to
                 herein as the "Adjustment Percentage".

         (c)     If the Adjustment Percentage is greater than or equal to 95%
                 and less than or equal to 105%, there shall be no adjustment
                 to the Formula Payment.

         (d)     If the Adjustment Percentage is greater than 105%, then the
                 Formula Payment to be paid in accordance with this Schedule IV
                 shall equal the product of AM's Annualized After Tax Revenues
                 multiplied by 3.33.

         (e)     If the Adjustment Percentage is less than 95%, then the
                 Formula Payment to be paid in accordance with this Schedule IV
                 shall equal the product of AM's Annualized After Tax Revenues
                 multiplied by 3.50.

         (f)     For purposes of calculating "AM's Annualized After Tax
                 Revenues" and the "Adjustment Percentage" in sections (a) and
                 (b) above, if the Triggering Event occurs during the period
                 January 1, 1995 through June 30, 1998, the Floor Incentive
                 shall be treated in the same manner as it is treated in
                 Section 10(b) of the Employment Agreement for purposes of
                 calculating the Section 11 Formula Payment.

                                 Schedule VI

TO:      Neal Finnegan

FROM:    Domenic Colasacco

DATE:    September 14, 1994

RE:      Capital Expenditure/Intercompany Charges
--------------------------------------------------------------------------------

         As you requested, this memorandum summarizes our agreement in
addressing the issues of capital expenditures and intercompany charges within
the new operating structure that is being finalized between the Asset
Management Division of United States Trust Company (USTC) and UST Corp.

         I will begin with capital expenditures.  Our discussion earlier this
summer contemplated continuing to account for capital expenditures in a manner
similar to existing practice.  Specifically, UST Corp. would leave sufficient
assets in USTC to pay for needed furniture, equipment and other capital items.
These items would be depreciated over standard UST Corp. time periods.  The
annual depreciation would be charged to the USTC Asset Management 60% revenue
share.  IN the past, USTC Asset Management has not been allocated an interest
charge on the un-depreciated portion.  We agreed that an interest charge would
be appropriate going forward.  The rate I propose is the equivalent U.S.
treasury note yield for the average life of the depreciation period of the
capital asset.  For example, a 5 year, straight line depreciation asset would
carry the same rate (and charge to USTC Asset Management) as a 2-1/2 year U.S.
Treasury note at the time of the asset purchase.

         Understandably, you had some concern on the potential size of the
capital budget.  A combination of empirical evidence and the nature of the
business suggest that the potential amounts are low relative to the anticipated
income stream.  A total of $526,921 has been spent on all Asset Management
capital items since 1986, which is as far back as I was able to obtain records.
Most of the funds were expended for furniture, telephone and computer
equipment.  As of June 30, 1994, $247,337 had yet to be depreciated.  USTC's
capital, of which the $247,337 is a part, was nearly $3 million at month end.
Most of this capital has been invested in Fed funds and the UST Capital Corp.
subsidiary.  The attached August 31, 1994 USTC Balance Sheet outlines the
specific breakdown.

         The largest capital expenditure I expect over the next several years
will be furniture related to space modernization.  Walter is in a better
position to forecast an amount, but I would be surprised if it will total more
than $300,000.  Other than furniture, computer replacements/upgrades are likely
to be the largest expenditures.





                                      30
<PAGE>   30
These should total less than $200,000 per annum.  The possible exception is
funding required to initiate a mutual fund.  I would expect that UST Corp.
would have to provide prior approval for capital spending above these
anticipated levels, adjusted only for changes in the size of the asset
management business.

         With respect to intercompany charges, in an early negotiating session
you mentioned the concept of offsetting general holding company overhead
allocation (Directors, management, corporate advertising, human resources,
legal, accounting, etc.) with non-direct fee advantages, mostly deposits, of
the asset management business.  Only more direct easily accountable expenses
would be charged to the 60% Asset Management revenue share.  Examples of such
charges include rent, telephone, travel, employee benefits, direct marketing,
stationery, etc.  As per regulatory requirements, we all agreed that such
charges would be at a fair, arms-length market rate.  As was the case at the
time of the discussion, I see no issues in incorporating the above-described
capital expenditure and overhead allocation understanding in the new operating
agreement.  This practice would also be consistent with the approach used over
the past 10 years.

         Please let me know if I have neglected to cover any relevant items or
if you have any questions on the above.

                                                            EXHIBIT 10(y)(ii)

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

         AGREEMENT made as of February 14, 1995 and effective January 1, 1995
between United States Trust Company ("USTC"), a banking and trust company
having its principal place of business in Boston, Massachusetts, and joined in
as to certain matters by UST Corp. ("UST"), a Massachusetts corporation also
having its principal place of business in Boston, Massachusetts and the parent
of USTC; and Robert A. Lincoln (the "Employee").

                                  BACKGROUND
                                  ----------

         The Employee and the other principals of the Asset Management Division
of USTC ("AM") listed on Schedule I hereto and such other principals as may be
added pursuant to the Unifying Agreement (as hereinafter defined) (all such
employees, while they remain principals, being referred to herein from time to
time as "Employee/Principals") are concerned that previous UST and USTC
practices have not allowed for enough spending to generate growth in AM's
business, or for fully competitive compensation for its principals; want
assurances of continued freedom to manage the AM business; want to participate
in an incentive compensation program which reflects the value created in this
business; and want to make it attractive to any potential acquirer of UST, USTC
or AM to (i) protect existing relationships with AM employees and clients, (ii)
avoid re-writing existing client contracts, and (iii) further AM as a separate
business conducted under the name "United States Trust Company".

         UST and USTC want to stabilize and increase the profitability of AM;
pay competitive compensation; provide incentive compensation reflecting the
growth in the business of AM; and (in the event of a "Triggering Event" as
hereinafter defined) offer an opportunity to a prospective purchaser to retain
the services of Employee and the other Employee/Principals and thereby receive
a continuing stream of profits from AM.

         UST and USTC recognize the importance of Employee to their business
and to USTC's ability to retain AM client relationships, and desire that USTC
employ Employee as an officer and principal of AM for the period of employment
and upon and subject to the terms herein provided.

         UST and USTC wish to be assured that Employee will not compete with
AM's business during the period of employment, and in certain circumstances and
as set forth below will not for a period thereafter solicit any Past, Present,
or Potential Clients (as hereinafter defined) of AM and will not by such
solicitation damage USTC's and AM's goodwill among its clients and the general
public.

                                      1
<PAGE>   2
         Employee desires to be employed by USTC and serve as an
Employee/Principal of AM and to participate in the incentive compensation
program contemplated by this agreement, and to refrain from competing with USTC
or AM or soliciting AM's clients for the periods and upon and subject to the
terms herein provided.

         Employee has been employed by USTC and AM for approximately 21 years;
has while so employed contributed to the acquisition and retention of AM's
clients, and will continue to seek to acquire and retain clients and to
generate goodwill for AM in the future as an officer and employee of USTC and
an Employee/Principal of AM for the periods and on the terms contemplated
hereby.

         When the terms "AM," "AM's business," or the "AM Division" are used
herein, such terms specifically exclude the non- investment advisory business
of USTC such as (1) the business of UST Capital Corp. (venture capital) and (2)
the management of USTC's internal securities portfolio.  Such terms, however,
include the investment return on allocated, but unexpended, portions of AM's
Share of Revenues as reflected on Schedule V. The investment return on
allocated, but unexpended, portions of AM's share of revenues shall be measured
at the end of each calendar quarter by multiplying the average of the month end
balances during such quarter by the published thirteen week U.S. Treasury Bill
Rate at the end of such calendar quarter and such interest income shall be
added to "AM's Share of Revenues".  All current Employee/Principals are listed
on Schedule I.

         Employee, the other Employee/Principals, UST and USTC have entered
into an agreement of even date herewith (the "Unifying Agreement") which
describes generally their agreements and certain procedures they have agreed to
follow among themselves.  This Employment Agreement is executed pursuant to and
in accordance with the terms of the Unifying Agreement.  Certain capitalized
terms used but not defined herein shall have the meanings given them in the
Unifying Agreement.

                                  AGREEMENTS
                                  ----------

         In consideration of the premises, the mutual covenants and the
agreements hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
covenant and agree as follows:

         SECTION 1.  ORIGINAL TERM OF EMPLOYMENT; COMPENSATION.  USTC
agrees to employ Employee for a period of two and one-half (2 1/2) years
beginning on the date hereof (the "Original Term") as an officer of USTC and an
Employee/Principal of AM; and Employee hereby accepts such employment.  USTC
will pay Employee for Employee's services during the Original Term, and any
Renewal Term (as hereinafter provided) and any Phase II Term, the Annual Base
Salary set forth on Schedule I hereto, and such additional annual incentive
payments as shall be determined by the 


                                      2
<PAGE>   3
Employee/Principals consistent with the Revenue Sharing Provision (Section 10
hereof),  and subject to such payroll and withholding deductions as are
required by law.  Consistent with the Revenue Sharing Provision, the Employee's
total compensation will be reviewed at least annually in accordance with the
Unifying Agreement, having in mind that such compensation be fair and
reasonable in light of Employee's position and the duties to be performed by
the Employee and the Employee's efforts to enhance the business of AM.

         SECTION 2.  RENEWAL TERMS.  If no "Triggering Event" has occurred
and this Agreement has not been terminated by either party (all as hereinafter
provided) prior to the end of the Original Term, then the Original Term shall
be automatically extended for successive six month renewal terms (each referred
to herein as a "Renewal Term", or collectively as "Renewal Terms") until such
Triggering Event or termination has occurred, or until the Employee shall have
provided at least six months advance written notice to UST and USTC of election
not to enter a Renewal Term.

         SECTION 3.  NOTICE OF TERMINATION OF ORIGINAL TERM BY EMPLOYEE.
On or before the last day of the second year of the Original Term and assuming
that this Agreement has not been earlier terminated or entered upon the Phase
II Term (all as hereinafter provided), the Employee may give written notice to
UST and USTC of termination, whereupon all the provisions of this Agreement
will terminate (except as noted below in this Section 3) on the last day of the
Original Term.  If there has been a material breach of this Agreement by
Employee at any time during the Original Term or any Renewal Term, and the
arbitration under Section 18 hereof has confirmed that a material breach has
been committed by the Employee and such breach is uncured during the applicable
grace period, then the Employee will be subject in full to all of the
restrictions of Section 12, 13 and 14 hereof for the remainder of the
applicable term plus 90 days.  However, should the Employee terminate this
Agreement without a material breach at the end of the Original Term or at the
end of any Renewal Term, Sections 12, 13 and 14 of this Agreement shall not
apply.  Notwithstanding the foregoing, should the Employee terminate this
Agreement as described in either of the immediately preceding two sentences,
UST and USTC will retain all of their respective common law rights against the
Employee with respect to confidentiality, protection of customer lists, trade
secrets, non-competition and similar matters.

         SECTION 4.  PHASE II TERM.  If a Triggering Event occurs during
the Original or a Renewal Term, any such term shall automatically terminate and
the Phase II Term shall commence as of the earlier of the date of signing of a
definitive merger or acquisition agreement or the date of occurrence of such
Triggering Event.  The Phase II Term shall be for a period of three years from
the Closing Date under such definitive merger, consolidation or acquisition
agreement, or the date of the agreement related to any other such Triggering
Event, but in no event for longer than four years from such signing date, and
shall be terminable in the same manner as the Original


                                      3
<PAGE>   4

Term under Section 3 above (the "Phase II Term"). The "Closing Date" shall mean
the date on which the merger or consolidation becomes effective, the
acquisition is consummated or the change in corporate ownership related to any
other such Triggering Event takes effect. If the revenues of the AM business
decline precipitously and the Formula Payment described in Section 11 below
would be less than $3 Million, then the Employee may decline to accept the
Formula Payment and the Phase II Term.  If the AM revenues likewise decline,
and the Formula Payment described in  Section 11 below would be less than $5
Million, the Employee/Principal may elect to reduce the Phase II Term by one
year.

         SECTION 5.  TERMINATION BY EMPLOYEE FOR BREACH OF "INDEPENDENCE
ASSURANCES."  In the event of the material breach by UST or USTC (or their
respective successors) of any one or more of the "Independence Assurances"
listed below, the Employee/Principals, acting in accordance with the Unifying
Agreement, shall have the right (subject to compliance with Section 18 hereof)
but not the obligation, upon 30 days prior written notice to UST and USTC, to
terminate this Agreement.

         (a)     "Independence Assurances" shall consist of UST's and USTC's
non-interference (unless requested by the Employee/Principals of AM acting in
accordance with the Unifying Agreement) in the following:

                 (i)  The Employee/Principals control of AM's investment
philosophy and investment approach, business strategy, conduct of investment
analysis, portfolio selection, marketing, client retention and acceptance of
new clients, and client service;

                 (ii)  Authority of the Employee/Principals to hire and fire AM
personnel within the scope of UST's "Policies" (as hereinafter defined) and
applicable Federal and Massachusetts laws, subject to UST's right to approve
any person chosen by the Employee/Principals as the Senior Principal of AM,
which person shall also serve initially (i) as the Chief Executive Officer of
USTC, and (ii) on USTC Board of Directors.  UST, as sole shareholder of USTC,
subject to the terms of the Unifying Agreement and this Agreement, will at all
times retain the right to select a Chief Executive Officer of USTC who is not
an employee of AM.  USTC will not, however, select the Senior Principal;

                 (iii)  The Employee/Principals' authority to set AM client
fees based on their judgment concerning the market for services rendered by AM;

                 (iv)  The Employee/Principals' authority to establish AM's
operating expense budget and compensation practices, limited by "AM's Share of
Revenues" as provided in Section 10 (See Schedule V for example); and limited
further with respect to total cumulative cash incentive compensation for
Employee/Principals in the aggregate accrued in each of the years ending
December 31, 1994 and December 31, 1995, to $1.3 million plus incentive
compensation accrued in 1993 (it being understood 


                                      4
<PAGE>   5
that the Formula Payment is not to be regarded as cash incentive compensation
for any purposes);

                 (v)   The Employee/Principals' authority to add and delete
Employee/Principals of AM in accordance with the Unifying Agreement; and

                 (vi)  The recognition by UST and USTC that AM, in pursuit
of its "socially-sensitive" investment objectives, may take some public
positions which may not represent the views of UST or USTC management.  The
Employee, however, recognizes that Employee's actions will remain subject to
the provisions of the Code of Ethics, Employment Policies, and certain other
key corporate policies of UST and USTC listed on and attached to Schedule II
hereto ("Policies"), as revised from time to time on a company-wide basis in
the ordinary course of UST's and USTC's business (which revisions shall be made
available to Employee at UST's principal office in Boston); and applicable
Federal and Massachusetts laws, regulations, policies, orders or understandings
in use by or applicable to UST and USTC.

         (b)     In the event that any of the "Independence Assurances" have
been  materially breached and not cured pursuant to Section 18, the Employee
may act either individually or in concert with any other Employee/Principal or
Employee/Principals or other employees so as to constitute a "person" as
defined in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the
"Exchange Act"), in electing to terminate their Employment Agreements, e.g.
they may collectively decide to give five (5) days notice and leave USTC to
form a new business which may directly compete with AM's business and Sections
12, 13 and 14 of this Agreement will not apply.

         SECTION 5A.   OVERSIGHT FUNCTION OF USTC'S BOARD OF DIRECTORS.
USTC's Board of Directors (a majority of whom shall not be Employee/Principals)
shall continue to exercise its oversight function of the business activities of
AM.  In performing such oversight function, USTC's Board the Directors will
assure itself that AM's business and operations are being conducted in a manner
consistent with applicable law and regulations, and such Board will be expected
to meet its fiduciary responsibilities to USTC and its depositors, and to UST,
in all respects, including without limitation, the prevention of corporate
waste of assets and taking steps to see that AM's business is operated with
their respective best interests in mind.  If in performing such oversight
function, the Board causes UST or USTC to breach an Independence Assurance and
such breach is (a) confirmed by the arbitrator under Section 18 or not
contested by UST or USTC and (b) not cured within the applicable grace period,
the Employee may terminate this Agreement and the Employee will leave with the
rights described in Section 5(b) of this Agreement.

         SECTION 6.       MATTERS NOT CONSTITUTING "INDEPENDENCE ASSURANCES".
The following shall specifically not be considered as "Independence Assurances"
but shall nevertheless govern the relationship by and among UST, USTC and AM:





                                      5
<PAGE>   6
         (a)     The location of AM's business for a period of three years from
January 1, 1995 on two floors at 40 Court Street, Boston, MA.  The Employee and
the other Employee/Principals shall cause AM to give twelve months written
notice of termination of such occupancy, if they so elect, no earlier than
December 31, 1996.  "Fair Rental" shall be charged or allocated by UST or USTC
for AM's premises, and UST or USTC shall give AM "high priority" with respect
to remodeling and upgrading of space.

         (b)     Matters covered in a Memorandum dated September 14, 1994 on
"Capital Expenditures/Intercompany Charges" which is attached as Schedule VI
hereto.

         (c)     The taking of reasonable steps by the Employee and the other
Employee/Principals to cause that appropriate levels of profit from AM's
business to be reinvested in the business (infrastructure, systems, facilities,
product development, compensation to staff members who are not Principals,
additional staff) during the Total Term (as hereinafter defined).  For the year
1995, the amount considered "appropriate" would be the investment of
approximately five percent (5%) of "Base Annual Revenues of AM" as defined in
Section 10.

         (d)     The amortization of AM capital expenditures over a period in
accordance with UST's and USTC's then current policy to the extent it is
consistent with GAAP.  In connection with the foregoing capital expenditures,
at the reasonable request of AM funding will be provided by UST and/or USTC
which will charge AM a fair interest rate for the cost of capital employed.
(See also Schedule VI).

         (e)     The providing of such information as is reasonably necessary
for UST to manage its affairs and responsibilities subject to client
confidentiality, including but not limited to information necessary to comply
with generally accepted accounting principles ("GAAP") in the preparation of
financial statements, budgets and profit plans, and for shareholder
communications, and responses to regulatory requests.

         (f)     The actions of all Employee Principals shall remain subject,
without limitation, to the terms of UST's Code of Ethics, the Payment Approval
Policy and the other Policies set forth in Schedule II hereto.

         SECTION 7.   TERMINATION OF EMPLOYMENT BY USTC.
                      ----------------------------------

         (a)     Employee's employment may be terminated by USTC (by majority
vote of its Board of Directors) in the following circumstances:

                 At any time after due notice and reasonable opportunity to
                 correct such conduct, (i) in the event of Employee's material
                 breach of any of the terms of this Employment Agreement; (ii)
                 in the event of Employee





                                      6
<PAGE>   7
                 causing a material breach of any of the other
                 Employee/Principals' duties to UST and USTC under Section 10
                 (Revenue Sharing Provision ); (iii) in the event of Employee's
                 willful misconduct in the performance of the Employee's duties
                 hereunder including, without limitation, but subject to
                 Sections 5 and 6 hereof, Employee's willful refusal to carry
                 out any "proper direction" by USTC's Board of Directors with
                 respect to the services to be rendered by Employee hereunder
                 or the manner of rendering such services; or (iv) in the event
                 of Employee's conviction of a crime involving moral turpitude.
                 The term "proper direction" as used in clause (iii) above, may
                 not be used in connection with an instruction, direction or
                 order which would cause UST or USTC to violate an
                 "Independence Assurance".

         (b)     In the event of Employee's death during the term of
employment,  unless otherwise determined by the Employee/Principals acting
pursuant to the Unifying Agreement, USTC's and UST's obligations to pay further
compensation hereunder shall cease as of the date of death, except that any
amounts due under Section 11 hereof or otherwise owed to Employee under welfare
or benefit plans or for deferred compensation and any amounts heretofore
accrued under Sections 3.1 and 3.2 of the Unifying Agreement, shall be paid
when due to the Employee's estate or named beneficiary.

         SECTION 8.   OFFICE AND DUTIES.  During the Original Term, any
Renewal Term, and the Phase II Term, if any, (hereinafter the "Total Term"),
Employee shall hold such positions and perform such duties relating to AM's
business and operations as are described on Schedule I hereto, and as may
otherwise from time to time be assigned to Employee by the Employee/Principals
consistent with all of the terms of this Agreement.  During the Total Term and
while employed by USTC, Employee shall devote (except as noted on Schedule I)
substantially all of Employee's business time to the Employee's duties
hereunder and shall, to the best of Employee's ability, perform such duties in
a manner which will faithfully and diligently further the business and
interests of AM.

         At any time while employed by USTC, Employee shall not directly or
indirectly solicit the business of any Past, Present, or Potential Clients (as
hereinafter defined) except on behalf and for the benefit of AM, or pursue any
other business activity, including, without limitation, serving as an officer,
director, employee, or adviser to any business entity other than AM, without
UST's and USTC's prior written consent; provided, however, that Employee may
without such consent, render without compensation investment advisory services
to immediate members of Employee's family, which shall include the Employee and
any trust or account which is comprised entirely of assets held for the benefit
of such Employee and/or immediate members of Employee's family, and may be
involved in such additional activities without such consent as are listed on
the Schedule I hereto.  Employee agrees to travel to whatever





                                      7
<PAGE>   8
extent is reasonably necessary in the conduct of AM's business.  Except when
engaged in such travel, Employee's place of employment shall be in the greater
Boston area of Massachusetts unless otherwise agreed to by Employee, UST and
USTC, and the Employee/Principals acting in accordance with the Unifying
Agreement.

         The term "Past Client" shall mean at any particular time any person or
entity who within three years prior to such time had been but at such time is
not an advisee, investment advisory customer, or client of AM.

         The term "Present Client" shall mean at any particular time any person
or entity who is at such time an advisee, investment advisory customer, or
client of AM.

         The term "Potential Client" shall mean at any particular time any
person or entity to whom AM, through any of the Employee/Principals or other of
its employees, has within three years prior to such time offered (by means of a
personal meeting, telephone call, or a letter or a written proposal
specifically directed to the particular person or entity) to serve as
investment adviser but who is not at such time an advisee or investment
advisory customer or client of AM.  The preceding sentence is meant to exclude
form letters and blanket mailings.

         The terms "Client" or "Client List" when used herein shall mean all
Past, Present, and Potential Clients as heretofore defined.  The term "Client"
when used in this Employment Agreement with respect to wrap accounts, shall
mean the wrap sponsors and the brokers employed by such wrap sponsors but not
the underlying wrap account holders.

         SECTION 9.   BENEFITS.  Employee shall participate, to the extent
Employee is eligible and in a manner and to an extent that is fair and
appropriate in light of the position and duties granted to Employee hereunder,
in all pension, profit-sharing, group insurance, or other fringe benefit plans
(other than UST corporate stock compensation plans) which UST or USTC may
hereafter in their absolute discretion make available generally to employees of
AM, but neither UST nor USTC will be required to establish any such program or
plan.  Employee shall be entitled to such vacations and to reimbursement of
such expenses as UST's or USTC's policies allow to all employees having
comparable responsibilities and duties.  So long as such additional benefits
are payable out of or accrue to "AM's Share of Revenues" as hereinafter
defined, the Employee/Principals may provide additional executive benefits to
themselves in addition to those provided by UST, provided that no such benefit
be qualified under Section 401 of  the Internal Revenue Code or non-qualified
(under Section 401 of the Internal Revenue Code) pursuant to the terms of a
plan or arrangement which operates in a manner that is substantially similar or
mirrors a qualified plan, and provided further that the award of any such
benefits does not increase the cost to UST of providing benefits to UST
employees who are not employees of AM.

         SECTION 10.    REVENUE SHARING PROVISION.  The purpose of this
Revenue Sharing Provision is to provide UST with an acceptable stream of income
and to permit AM to retain a specified percentage of its revenues for use by
Employee/Principals, including the Employee, in their discretion in paying
expenses of operation, including compensation.  It is intended to allow the
Employee and the other Employee/Principals to be compensated for enhancing and
growing AM's revenues in a substantial manner and to make operating decisions
freely within the limits of "AM's Share of Revenues," as such term is defined
below.  See Schedule V for examples of Revenue Sharing calculations.

         (a)    ALLOCATION OF REVENUES.  "Base Annual Revenues of AM" in 1994
and all subsequent years for purposes of this Revenue Sharing Provision shall
be AM's actual 1994 Revenues less $750,000, such total amount to be
appropriately modified to reflect changes in the United States Bureau of Labor
Statistics Cost of Living Index for the Boston Metropolitan Statistical Area or
any designated successor index for 1995 and all subsequent years.  The term
"Revenues" shall mean AM's revenues calculated on an accrual basis in
accordance with GAAP, (excluding shared revenues paid to investment or other
firms or professionals and generated from AM clients), consistent with USTC's
usual practice.

         During the pro-rated six month period commencing July 1, 1994 and
         ending December 31, 1994, and for each calendar year and for portions
         thereof on a pro-rated basis thereafter, AM shall retain sixty percent
         (60%) ("Base AM Retention"), of AM's pro-rated actual Revenues and AM
         shall make available to USTC for distribution to UST forty percent
         (40%) ("Base UST Amount"), subject to adjustment as set forth in this
         Section 10(a).

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar of AM's annual revenues
         over Base Annual Revenues of AM, AM shall retain an additional $.40,
         and an additional $.60 shall be allocated to UST, provided that in no
         event shall UST's Share of Revenues exceed fifty percent (50%) of
         actual Annual Revenues of AM.

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar that actual Annual
         Revenues of AM are less than Base Annual Revenues of AM, Base AM
         Retention shall be reduced by $.40 and the Base UST Amount shall be
         reduced by $.60, provided that in no event shall  UST's Share of
         Revenues be less than thirty percent (30%) of Annual Revenues of AM.

         Amounts retained by AM as aforesaid are herein referred to as "AM's
Share of Revenues".  Amounts allocated to UST as aforesaid are herein referred
to as "UST's Share of Revenues".





                                      9
<PAGE>   10
         (b)     FLOOR INCENTIVE.  In addition, during the Original Term of
this Agreement (thirty months), AM shall retain a "Floor Incentive" of $40,000
per month from "UST's Share of Revenues" ($1.2 million in the aggregate).  The
"Floor Incentive" shall be accrued by USTC and paid pursuant to subsection
(d)(iv) hereof, and shall be excluded from the limitations of Section 5(a)(iv)
of this Agreement.  In the event of a material breach by UST or USTC of this
Agreement during the Original Term (which breach is not cured during the
applicable grace period and is either confirmed by the arbitrator under Section
18 hereof or not contested by UST or USTC), the Employee/Principals (for
distribution in accordance with the Unifying Agreement) may elect to receive an
aggregate lump-sum payment determined by multiplying (x) the monthly "Floor
Incentive" by (y) the remaining months in the Original Term.  If a "Triggering
Event" occurs during the period January 1, 1995 through June 30, 1998, the
aggregate Floor Incentive, net of tax, accrued during the four full calendar
quarters next preceding the date of the Triggering Event, shall not be deducted
from "AM's After Tax Revenues" for purposes of calculating the Section 11
Formula Payment.  Moreover, if a Triggering Event occurred before all Floor
Incentives have been paid, UST or USTC's successor shall assume responsibility
to make the remaining Floor Incentive payments.

         (c)     SPECIAL PROVISIONS.  It is understood and agreed that:

                 (i)      The balance of "Base AM Retention" for the period
                          July 1, 1994 through December 31, 1994 shall be paid
                          by UST or USTC to AM no later than February 15, 1995.

                 (ii)     All amounts due to Robert B. Zevin pursuant to his
                          agreement dated September 30, 1994 with USTC shall be
                          considered as expenses to come out of "AM's Share of
                          Revenues" in each year in accordance with the
                          Unifying Agreement.

                 (iii)    The application of this Section may make it
                          unattractive for AM to enter a business activity with
                          a profit margin of less then 40%.  Accordingly, the
                          parties have agreed to negotiate separate "side
                          letters" with respect to revenue sharing on any new,
                          lower-margin business opportunities identified in the
                          future by AM and regarded as worthy of pursuit by UST
                          and/or USTC.

                 (iv)     The parties hereto further understand and acknowledge
                          that the term "Revenues" as used herein is intended
                          to cover revenues of AM as they now exist and as they
                          may grow or contract internally, and not revenues
                          from the acquisition by UST or USTC of another
                          investment advisory firm concerning which the parties
                          hereto agree to negotiate in good faith as to revenue
                          sharing.

                 (v)      The investment return on allocated, but unexpended,
                          portions of AM's Share of Revenues shall be measured
                          at the end of each calendar quarter by multiplying
                          the average of the month end balances during such
                          quarter by the published thirteen week U.S. Treasury
                          Bill Rate at the end of such calendar quarter.This
                          interest income shall be added to "AM's Share of
                          Revenues".

         (d)     Transfer of Revenues to UST; Retention of Revenues by
                 -----------------------------------------------------
                 USTC;Compensation of Employee/Principals.
                 -----------------------------------------

                 (i)      The Employee/Principals and AM shall use AM's Share
                          of Revenues to pay and provide for AM's business
                          expenses and expenditures including, without
                          limitation, investment in AM's business and new
                          products (see Section 6(d) above) and salaries of its
                          employees, except that any federal, state or local
                          income tax to which USTC is subject shall be the
                          responsibility of UST and shall not be treated as a
                          business expense of AM.

                 (ii)     The Employee/Principals shall incur no expenses or
                          obligations on behalf of AM which exceed USTC's
                          ability to pay or provide for them when due out of
                          AM's Share of Revenues.  The Employee/Principals
                          shall not incur obligations or make binding
                          commitments on behalf of USTC or UST not related to
                          AM's business and requiring expenditures by USTC in
                          excess of $50,000, or make representations to third
                          parties that they have the authority to do so.
                          However, the Employee/Principals may represent and
                          advertise that AM is a division of USTC and an
                          affiliate of UST, and other than as limited above in
                          this Section 10 (d)(ii), may incur obligations or
                          make binding commitments on behalf of USTC in the
                          ordinary course of business.

                 (iii)    The Employee/Principals may (subject to Policies and
                          applicable laws and regulations) pay to AM's
                          employees, including the Employee and the other
                          Employee/Principals, at times and in amounts and
                          proportions determined in accordance with the
                          Unifying Agreement, the balance of AM's Share of
                          Revenues remaining after the payment of all of the
                          amounts required under subsection (d)(i) hereof and
                          subject to Section 5(a)(iv).

                  (iv)    The Employee's Revenue Sharing compensation out of
                          "AM's Share of Revenues" shall be allocated in
                          accordance with the terms of the Unifying Agreement.
                          The Employee/Principals have provided to UST and USTC
                          in the Unifying Agreement their procedures for
                          determining changes, if any, in the allocation of





                                      11
<PAGE>   12
                          Revenues among the Employee/Principals.  If an
                          Employee/Principal chooses to leave USTC's employ
                          after bypassing this change determination mechanism
                          or refusing to abide by its results, the
                          Employee/Principal shall be deemed to have committed
                          a material breach of this Employment Agreement.

                 (v)      The Employee/Principals and AM shall make available
                          to UST, UST's Share of Revenues upon reasonable
                          request by UST and action by USTC's Board of
                          Directors.  The Employee/Principals shall not spend
                          or incur obligations to spend any part of UST's Share
                          of Revenues.

         (e)     ADMINISTRATION.  The parties hereto and the other
Employee/Principals agree to meet and consult to endeavor in good faith to
agree on appropriate procedures, in addition to Policies and applicable laws
and regulations,  for administering the provisions of this Section 10.

         The Employee/Principals shall retain control over all expenditures of
AM, subject to the power of USTC's Board of Directors to exercise its rights
under Section 5A, and subject to this Revenue Sharing Provision, and
recognizing that AM is a division of USTC.

         (f)     TERM AND STATUS AS PARTIES.  This Revenue Sharing Provision
shall continue in effect until terminated by agreement of UST, USTC, and the
Employee/Principals acting in accordance with the Unifying Agreement.  If the
employment of Employee by USTC ceases other than as a result of a material
breach by UST or USTC of this Employment Agreement, such Employee shall
thereupon automatically cease to be a party to this Revenue Sharing Provision
and to have any rights or obligations under this Section, and shall cease to be
an Employee/Principal for the purposes of this Provision.  Nothing  in this
Employment Agreement shall be construed to grant to the Employee any right to
be employed by USTC beyond the terms of this Employment Agreement.

         SECTION 11.      FORMULA PAYMENT.  If Employee is still employed by
USTC at the time of a "Triggering Event" (as hereinafter defined), the Employee
shall receive Employee's share of a formula payment (the "Formula Payment") as
follows:

         (a)     Unless otherwise agreed by the Employee/Principals acting in
accordance with the Unifying Agreement, the Employee's share of the Formula
Payment shall be the percentage set forth after the Employee's name on Schedule
III hereto;

         (b)     The "Formula Payment" shall be 3.33 times "AM's After Tax
Revenues" (as hereinafter defined and meaning generally UST's Share of Revenues
minus taxes);





                                      12
<PAGE>   13
         (c)     "AM's After Tax Revenues" shall be the portion of AM's
after-tax Revenues contributed, accruing or allocated to UST for the four full
calendar quarters next preceding the date of the Triggering Event; determined
in accordance with GAAP consistently applied in such periods.  For purposes of
this Subsection, there shall be assumed a combined federal and state tax rate
of 38%, such rate to be appropriately adjusted to reflect changes in applicable
federal and state corporate tax rates.  An example of this calculation is set
forth on Schedule V.

         (d)     The Formula Payment shall be adjusted in accordance with
Schedule IV hereto for gain or loss of AM clients between the signing of a
definitive merger, consolidation or acquisition agreement or an agreement
related to another Triggering Event and the Closing Date related to any such
Triggering Event.

         (e)
                 (i)      At the Closing Date of a Triggering Event, three Key
                          Employees shall be identified as follows.  For every
                          person who has been an Employee/Principal at any time
                          during the previous 15 months there shall be
                          calculated a Weighted Average Share equal to the sum
                          of (a) the share of the Formula Payment such person
                          was entitled to receive from time-to-time during the
                          preceding 15 months in accordance with Schedule III
                          and subsequent changes thereto by the
                          Employee/Principals acting in accordance with the
                          Unifying Agreement times (b) the number of days such
                          person was entitled to each such share.  The three
                          persons among those who are or have been
                          Employee/Principals on the Closing Date of the
                          Triggering Event or during the previous 15 months who
                          have the three highest Weighted Average Shares shall
                          be deemed the "Key Employees".

                 (ii)     If only one of the three Key Employees is no longer
                          in the employ of USTC as of the Closing Date of such
                          Triggering Event, then all of that Key Employee's
                          Weighted Average Share of the Formula Payment
                          (expressed by X%) shall be placed in escrow in the
                          manner contemplated by Section 11(f). To determine
                          the distribution of each of the three escrowed
                          installments use the following formula.  Revenues of
                          AM (as defined in Section 10(a)) for the last full
                          calendar year prior to a Triggering Event should then
                          be determined (the "Measuring Year").  Such Revenues
                          of AM for the Measuring Year multiplied by a decimal
                          representing 100% - X% equals the "Minimum Revenues".
                          If during the next full calendar year following the
                          Measuring Year, Revenues of AM are equal to or less
                          than Minimum Revenues none of the one-third of the
                          escrowed amount for such year will be paid to the
                          remaining Employee/Principals in accordance with this
                          Section and all of it will be retained by UST's or
                          USTC's successor.  If Revenues of AM for





                                      13
<PAGE>   14
                          that calendar year exceed Minimum Revenues, (i) take
                          the U.S. Dollar amount of such excess above the
                          Minimum Revenues and divide it by the Revenues of AM
                          for the Measuring Year minus the Minimum Revenues,
                          (ii) then multiply the resulting fraction by
                          one-third of the full escrowed amount, (iii) the
                          product of the foregoing formula should be delivered
                          to the remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and the remainder of that installment
                          should be retained by UST or UST's successor.
                          Similar calculations should be made for the second
                          and third installments, but in each case using the
                          same Minimum Revenues.

                 (iii)    If two or more of the Key Employees are no longer in
                          the employ of USTC as of the Closing Date of such
                          Triggering Event, then 100% of the Formula Payment
                          shall be placed in escrow in the manner contemplated
                          by Section 11(f).  To determine the distribution of
                          each of the three escrowed installments use the
                          following formula.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment equal or exceed
                          Revenues of AM for the Measuring Year, all of that
                          escrowed installment should be distributed to the
                          remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and none should be retained by UST or
                          USTC's successor.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment are less than
                          Revenues of AM for the Measuring Year, divide the
                          U.S. Dollar amount of Revenues of AM for such last
                          full calendar year by the U.S. Dollar amount of
                          Revenues of AM for the Measuring Year and multiply
                          the resulting fraction by one-third of the full
                          escrowed amount.  The product of the foregoing
                          calculation should be delivered to the remaining
                          Employee/Principals as a group for distribution in
                          accordance with the Unifying Agreement and the
                          remainder should be retained by UST's or USTC's
                          successor.

         (f)     Seventy percent (70%) of the Employee's share of the Formula
Payment shall be paid in cash within twenty (20) days of the Closing Date of
the Triggering Event.  The remaining thirty percent (30%) shall be placed in
escrow with an escrow agent acceptable to both UST and Employee/Principals and
paid to the Employee or the Employee's estate as provided in Section 7(b) in
installments of one third of the escrowed amount at the end of years one, two
and three (which may not be calendar years) after the Closing Date of the
Triggering Event plus interest, at the interest rates on the date of the
Closing Date of the Triggering Event of one, two and three year Treasury
securities,  provided that at the time of each such installment payment, the
Employee has not been terminated with cause or for a material breach or has not
voluntarily ceased to be employed by AM.

         (g)     A "Triggering Event" shall be deemed to have occurred when:

                 (i)      there occurs the signing of a definitive agreement of
                          merger or consolidation of UST or USTC with any other
                          corporation, other than a merger or consolidation
                          which would result in the voting securities of UST or
                          USTC 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 USTC, or such surviving entity outstanding
                          immediately after such merger or consolidation;
                          provided, however, that a merger or consolidation
                          effected to implement a recapitalization,
                          reorganization or restructuring of UST or USTC (or
                          similar transaction) in which no "person" (as defined
                          in (g)(iii) below) acquires more than fifty percent
                          (50%) of the combined voting power of UST's then
                          outstanding securities shall not constitute a
                          Triggering Event; or

                 (ii)     there occurs a closing of a sale or other disposition
                          by UST of more than 50% of UST's, USTC's or AM's
                          business and assets; or

                 (iii)    any "person", as such term used in Section 13(d) and
                          14(d) of the Exchange Act other than UST or USTC or
                          any of their respective subsidiaries or affiliates or
                          any trustee or other fiduciary holding securities
                          under an employee benefit plan of either of them or
                          any of their subsidiaries or 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
                          50% percent or more of the combined voting power of
                          UST's or USTC's then outstanding securities.

         If (i) more than 50% of UST's then outstanding common stock or assets
are acquired by a "person" whose consolidated assets prior to the Triggering
Event were less than $4 billion or (ii) UST's business assets and operations
are consolidated with those of another bank or bank holding company and the
resulting entity has consolidated assets of $5.5 billion or less, a Triggering
Event shall be deemed to have occurred, but the length of the Phase II term of
employment of the Employee shall be increased automatically by one additional
year.

         (h)  If UST agrees to be acquired by an entity with a public image
so starkly negative that AM's affiliation with that entity would be reasonably
likely, by itself, to cause a loss of more than 25% of AM's gross revenues in
one year (unless the parties

                                      15
<PAGE>   16
mutually agree to the contrary), the Employee/Principals at their option acting
pursuant to the terms of the Unifying Agreement (and provided such right is
exercised within 30 days of the public announcement of such acquisition) will
be relieved of all of the Employee's obligations under the Phase II Term and no
Formula Payment will be made.

         (i)     The parties acknowledge that any such Formula Payment is
intended to compensate the Employee for: (i) the automatic extension of this
Agreement occurring by reason of a Triggering Event; (ii) the Phase II
Non-Competition covenants specified in Section 12; and (iii) the loss of
opportunity to make up for reduced rate of compensation which such Employee
earned with USTC for periods prior to the effective date of this Agreement.

         SECTION 12.  PHASE II NON-COMPETITION COVENANTS.
  
         (a)     During the longer of the Phase II Term (as defined in Section
4) if Phase II shall commence while Employee is employed by USTC hereunder or
while Employee is employed by USTC during or after such Phase II Term
hereunder, Employee shall not, except in the course of his employment with
USTC, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, stockholder,
                          consultant, adviser, subsidiary, affiliate,
                          independent contractor or otherwise, investment
                          advisory services to any person or entity;

                 (ii)     Interfere with AM's relations with any person or
                          entity who at any time during such period was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person, other than by
                          discharge of such person as a part of Employee's
                          duties.

         (b)     Until one year following the end of the Phase II Term, if the
Phase II Term should commence while Employee is employed by USTC hereunder or
one year following the termination of Employee's employment with USTC during or
after such Phase II Term, Employee shall not, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, independent
                          contractor or otherwise, investment advisory services
                          to any person or entity who as of the date of the
                          termination or expiration of Employee's employment


                                      16
<PAGE>   17
                          with USTC was or had been a Client (which means       
                          Past, Present, and Potential Client);

                 (ii)     Interfere with AM's relations with any person or
                          entity who as of the date of the termination or
                          expiration of Employee's employment with USTC was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person.

         (c)     Notwithstanding the provisions of subsections (a)(i) and
(b)(i), the Employee may render without compensation investment advisory
services to any immediate member of Employee's family, which shall include the
Employee and any trust or account which is comprised entirely of assets held
for the benefit of such Employee and/or immediate members of such Employee's
family, and may engage in such other activities as are listed on Schedule I
hereto.

         (d)     Employee and USTC agree that the periods of time and the
unlimited geographic area applicable to the covenants of this Section 12 are
reasonable, in view of the receipt and expected receipt of the Employee's share
of Revenue Sharing as provided in Section 10(c), and other compensation, and
the Formula Payment provided herein; the geographic scope and nature of the
business in which AM is engaged; Employee's knowledge of AM's business; and
Employee's relationships with AM's investment advisory clients.  However, if
such period or such area should be adjudged unreasonable in any judicial
proceeding, then the period of time shall be reduced by such number of months
or such area shall be reduced by elimination of such portion of such area, or
both, as are deemed unreasonable, so that this covenant may be enforced in such
area and during such period of time as are adjudged to be reasonable.

         SECTION 13.      ALL BUSINESS TO BE THE PROPERTY OF USTC; ASSIGNMENT
OF INTELLECTUAL PROPERTY.  During the Phase II Term if Phase II shall commence
while Employee is Employed by USTC hereunder and thereafter while Employee is
employed by AM and/or USTC:

         (a)     Employee agrees that any and all presently existing investment
advisory business of AM and all business developed by Employee or any other
employee of AM, including without limitation all investment advisory contracts,
fees, commissions, compensation records, Client Lists (as defined in Section
8), agreements, and any other incident of any business developed or sought by
AM or earned or carried on by Employee for AM, are and shall be the exclusive
property of USTC for its sole use, and (where applicable) shall be payable
directly to USTC.





                                      17
<PAGE>   18
         (b)     Employee hereby grants to USTC (without any separate
remuneration or compensation other than that received by Employee from time to
time in the course of his or her employment) Employee's entire right, title,
and interest throughout the world in and to, all research, information, Client
Lists, and all other investment advisory, technical and research data made,
conceived, developed and/or acquired by Employee solely or jointly with others
during the period of Employee's employment by USTC, which relate to investment
advice as it was or is now rendered or as it may, from time to time, hereafter
be rendered or proposed to be rendered, but excluding such individual's ideas
and thought processes which are not embodied in written or machine readable
form (all such non-excluded items being referred to as "Intellectual
Property").

         SECTION 14.      CONFIDENTIALITY.  Except in performance of services
for USTC, Employee shall not, either during the Phase II Term if Phase II shall
commence while the Employee is employed by USTC hereunder or thereafter while
employed by AM and/or USTC, use for Employee's own benefit or disclose to or
use for the benefit of any person outside USTC, any information not lawfully
available to the public concerning any Intellectual Property, including Client
Lists, whether Employee has such information in his or her memory or embodied
in writing or other tangible form.  All such Intellectual Property and such
information concerning Intellectual Property, and all originals and copies of
any Intellectual Property, and any other written material relating to the
business of AM, shall be the sole property of USTC.  During such Term or
thereafter, upon the termination of Employee's employment in any manner or for
any reason, Employee shall promptly surrender to USTC all originals and copies
of any Intellectual Property, and Employee shall not thereafter use any
Intellectual Property.

         The foregoing notwithstanding, Employee will have no obligation to AM
or USTC with respect to the disclosure or use of any Intellectual Property or
information concerning Intellectual Property if:

         (a)  Such Intellectual Property or information is or becomes publicly
known or otherwise enters the public domain through no wrongful act of
Employee; or

         (b)  Such Intellectual Property or information is received from a
third party which has no obligation to UST or USTC to maintain it in
confidence.

         Notwithstanding the references to Client Lists above, it shall not be
a violation of this Section or Section 13 hereof for Employee to communicate or
do business with any Past, Present or Potential Client in the course of
Employee's employment with AM and USTC, and any such conduct shall be limited,
if at all, solely by Section 12 hereof.

         SECTION 16.      ASSIGNABILITY.  This Employment Agreement shall be
binding upon and inure to the benefit of UST, USTC, and to any person or firm
who may succeed to the business of UST, USTC, or AM.  This Employment Agreement
shall not be assignable by Employee, but it shall inure to the benefit of
Employee's heirs, executors, administrators and legal representatives.

         SECTION 17.      ENTIRE AGREEMENT.  This Employment Agreement and the
Unifying Agreement contain the entire agreement between USTC and Employee with
respect to the subject matter hereof, and supersede all prior oral and written
agreements between any of UST, USTC, AM and the Employee with respect to the
subject matter hereof, including without limitation any oral agreements
relating to compensation.

         SECTION 18.      ARBITRATION.  In the event the parties hereto
disagree as to whether a material breach has occurred of: (i) the "Independence
Assurances" under Section 5; (ii) USTC's right of termination of Employee's
employment under Section 7; (iii) this Agreement by USTC as described in
Section 19 (b); (iv) the revenue sharing provisions of Section 10; or (v) the
formula payment provisions of Section 11, such dispute shall be settled by
arbitration before a single arbitrator to be then named by UST and a majority
of the Employee/Principals acting in accordance with the Unifying Agreement, in
Boston, Massachusetts in accordance with the Commercial Arbitration Rules of
the American Arbitration Association.  If such arbitrator cannot serve, then a
successor shall be appointed in accordance with such Rules.  If the arbitrator
finds that there has been a material breach (and such breach has not been cured
by UST or USTC within sixty (60) days of such finding or by Employee in
accordance with Section 7 hereof), then the remedies provided for in Section 19
shall become available, as appropriate.

         SECTION 19.      EQUITABLE RELIEF AND OTHER REMEDIES.

         (a)  Employee recognizes and agrees that UST's, USTC's or the
Employee/Principals' remedies at law for any breach of the provisions of
Sections 12, 13 and 14 hereof would be inadequate and that for breach of such
provisions UST, USTC and the Employee/Principals  shall, in addition to such
other remedies as may be available to any of them at law or in equity or as
provided in this Employment Agreement, be entitled to injunctive relief and to
enforce their respective rights by an action for specific performance to the
extent permitted by law, and to the right of set-off against any amounts due to
the Employee by UST, USTC or AM.  Should Employee engage in any activities
prohibited by this Employment Agreement, he or she agrees to pay over to USTC
or UST all compensation received in connection with such activities.  Such
payment shall not impair any other rights or remedies of UST, USTC or AM or
affect the obligations or liabilities of Employee under this Employment
Agreement or applicable law.

         (b)  Any termination by USTC of Employee's employment which is not
authorized by Section 7 hereof shall constitute a material breach of this
Agreement.  In the event of a material breach of this Agreement by UST or USTC
which is not cured pursuant to Section 18, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, USTC
shall pay Employee the Employee's then current Annual Base Salary for a period
equal to the greater of (i) twelve months or (b) the balance of the then
current term of this Agreement.  Any such payments shall not constitute part of
AM's Share of Revenues.  Should such a material breach occur and not be so
cured, the Employee shall be  free to compete, Sections 12, 13 and 14 shall not
apply and the Employee shall leave with the rights described in Section 5(b) of
this Agreement.

        (c)  Without limiting the generality of the foregoing, the parties 
expressly agree





                                      20
<PAGE>   21
that termination without cause of Employee's employment hereunder during the
Phase II Term by UST, USTC or any other person or entity will constitute a
material breach of this Agreement and, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, shall
give Employee the right to salary continuation as set forth in Section 19(b)
hereof.

         SECTION 20.      WAIVERS AND FURTHER AGREEMENTS.  Neither this
Employment Agreement nor any term or condition hereof, including without
limitation the terms and conditions of this Section 20, may be waived in whole
or in part as against UST, USTC, AM or Employee except by written instrument
executed by each of them, expressly stating that it is intended to operate as a
waiver of this Employment Agreement or the applicable term or condition hereof.
Each of the parties hereto agrees to execute all such further instruments and
documents and to take all such further action as the other party may reasonably
require in order to effectuate the terms and purposes of this Employment
Agreement as stated herein.  Furthermore, no waiver may violate the terms of
the Unifying Agreement and any waiver shall require action of the
Employee/Principals in accordance with the Unifying Agreement authorizing such
waiver.

         SECTION 21.      AMENDMENTS.  This Employment Agreement may not be
amended, nor shall any parties be added hereto, nor any change, modification,
consent, or discharge be effected except by written instrument executed by all
three of the Employee, USTC and UST.  Furthermore, no amendment or modification
may violate the terms of the Unifying Agreement and any amendment or
modification shall require action of the Employee/Principals in accordance with
the Unifying Agreement authorizing such amendment or modification.

         SECTION 22.      SEVERABILITY.  If any provision of this Employment
Agreement shall be held or deemed to be invalid, inoperative or unenforceable
in any jurisdiction or jurisdictions, because of conflicts with any
constitution, statute, rule or public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision in question
unenforceable in any other jurisdiction or in any other case or circumstance or
of rendering any other provisions herein contained unenforceable to the extent
that such other provisions are not themselves actually in conflict with such
constitution, statute or rule of public policy, but this Employment Agreement
shall be reformed and construed in any such jurisdiction or case as if such
invalid, inoperative, or unenforceable provision had never been contained
herein and such provision reformed so that it would be enforceable to the
maximum extent permitted in such jurisdiction or in such case.

         SECTION 23.      NO CONFLICTING OBLIGATIONS.  Employee represents and
warrants to USTC and UST that Employee has no other interest or obligation
which is inconsistent or in conflict with this Employment Agreement or which
would prevent, limit, or impair, in any way, Employee's performance of any of
the covenants or duties





                                      21
<PAGE>   22
hereinabove set forth.

         SECTION 24.      PARTIES.  It is understood and agreed that UST joins
in this Employment Agreement only as to such matters where its name appears
herein.  It is further understood and agreed that no person shall participate
in the benefits conferred on Employee/Principals by the terms of this and other
similar Employment Agreements unless such person has become a party to a
similar Employment Agreement or is described in Section 16.

         SECTION 25.      GOVERNING LAW.  This Employment Agreement shall be
governed by and construed and enforced in accordance with the laws of the
Commonwealth of Massachusetts which apply to contracts executed and performed
solely in Massachusetts.  UST, USTC and the Employee hereby consent to the
jurisdiction of any state or federal court located within Suffolk County,
Massachusetts, and assent that service of process may be made by registered
mail to the parties' respective addresses as provided in Section 15 hereof and
shall be effective in the same manner as notices are effective under such
Section 15.

         SECTION 26.      ACTION OF THE EMPLOYEE/PRINCIPALS.  Whenever the
Consent of the Employee/Principals shall be described herein, action by the
Employee/Principals or their duly authorized representative shall be required
in accordance with the Unifying Agreement, and such action shall be sufficient
hereunder.

         IN WITNESS WHEREOF, the parties have executed this Employment
Agreement as a sealed instrument as of the date first above written.

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

         AGREEMENT made as of February 14, 1995 and effective January 1, 1995
between United States Trust Company ("USTC"), a banking and trust company
having its principal place of business in Boston, Massachusetts, and joined in
as to certain matters by UST Corp. ("UST"), a Massachusetts corporation also
having its principal place of business in Boston, Massachusetts and the parent
of USTC; and Stephen K. Moody (the "Employee").

                                   BACKGROUND
                                   ----------

         The Employee and the other principals of the Asset Management Division
of USTC ("AM") listed on Schedule I hereto and such other principals as may be
added pursuant to the Unifying Agreement (as hereinafter defined) (all such
employees, while they remain principals, being referred to herein from time to
time as "Employee/Principals") are concerned that previous UST and USTC
practices have not allowed for enough spending to generate growth in AM's
business, or for fully competitive compensation for its principals; want
assurances of continued freedom to manage the AM business; want to participate
in an incentive compensation program which reflects the value created in this
business; and want to make it attractive to any potential acquirer of UST, USTC
or AM to (i) protect existing relationships with AM employees and clients, (ii)
avoid re-writing existing client contracts, and (iii) further AM as a separate
business conducted under the name "United States Trust Company".

         UST and USTC want to stabilize and increase the profitability of AM;
pay competitive compensation; provide incentive compensation reflecting the
growth in the business of AM; and (in the event of a "Triggering Event" as
hereinafter defined) offer an opportunity to a prospective purchaser to retain
the services of Employee and the other Employee/Principals and thereby receive
a continuing stream of profits from AM.

         UST and USTC recognize the importance of Employee to their business
and to USTC's ability to retain AM client relationships, and desire that USTC
employ Employee as an officer and principal of AM for the period of employment
and upon and subject to the terms herein provided.

         UST and USTC wish to be assured that Employee will not compete with
AM's business during the period of employment, and in certain circumstances and
as set forth below will not for a period thereafter solicit any Past, Present,
or Potential Clients (as hereinafter defined) of AM and will not by such
solicitation damage USTC's and AM's goodwill among its clients and the general
public.
<PAGE>   2
         Employee desires to be employed by USTC and serve as an
Employee/Principal of AM and to participate in the incentive compensation
program contemplated by this agreement, and to refrain from competing with USTC
or AM or soliciting AM's clients for the periods and upon and subject to the
terms herein provided.

         Employee has been employed by USTC and AM for approximately 21 years;
has while so employed contributed to the acquisition and retention of AM's
clients, and will continue to seek to acquire and retain clients and to
generate goodwill for AM in the future as an officer and employee of USTC and
an Employee/Principal of AM for the periods and on the terms contemplated
hereby.

         When the terms "AM," "AM's business," or the "AM Division" are used
herein, such terms specifically exclude the non- investment advisory business
of USTC such as (1) the business of UST Capital Corp. (venture capital) and (2)
the management of USTC's internal securities portfolio.  Such terms, however,
include the investment return on allocated, but unexpended, portions of AM's
Share of Revenues as reflected on Schedule V. The investment return on
allocated, but unexpended, portions of AM's share of revenues shall be measured
at the end of each calendar quarter by multiplying the average of the month end
balances during such quarter by the published thirteen week U.S. Treasury Bill
Rate at the end of such calendar quarter and such interest income shall be
added to "AM's Share of Revenues".  All current Employee/Principals are listed
on Schedule I.

         Employee, the other Employee/Principals, UST and USTC have entered
into an agreement of even date herewith (the "Unifying Agreement") which
describes generally their agreements and certain procedures they have agreed to
follow among themselves.  This Employment Agreement is executed pursuant to and
in accordance with the terms of the Unifying Agreement.  Certain capitalized
terms used but not defined herein shall have the meanings given them in the
Unifying Agreement.

                                   AGREEMENTS
                                   ----------   

         In consideration of the premises, the mutual covenants and the
agreements hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
covenant and agree as follows:

         SECTION 1.       ORIGINAL TERM OF EMPLOYMENT; COMPENSATION.  USTC
agrees to employ Employee for a period of two and one-half (2 1/2) years
beginning on the date hereof (the "Original Term") as an officer of USTC and an
Employee/Principal of AM; and Employee hereby accepts such employment.  USTC
will pay Employee for Employee's services during the Original Term, and any
Renewal Term (as hereinafter provided) and any Phase II Term, the Annual Base
Salary set forth on Schedule I hereto, and such additional annual incentive
payments as shall be determined by the





                                       2
<PAGE>   3
Employee/Principals consistent with the Revenue Sharing Provision (Section 10
hereof),  and subject to such payroll and withholding deductions as are
required by law.  Consistent with the Revenue Sharing Provision, the Employee's
total compensation will be reviewed at least annually in accordance with the
Unifying Agreement, having in mind that such compensation be fair and
reasonable in light of Employee's position and the duties to be performed by
the Employee and the Employee's efforts to enhance the business of AM.

         SECTION 2.       RENEWAL TERMS.  If no "Triggering Event" has occurred
and this Agreement has not been terminated by either party (all as hereinafter
provided) prior to the end of the Original Term, then the Original Term shall
be automatically extended for successive six month renewal terms (each referred
to herein as a "Renewal Term", or collectively as "Renewal Terms") until such
Triggering Event or termination has occurred, or until the Employee shall have
provided at least six months advance written notice to UST and USTC of election
not to enter a Renewal Term.

         SECTION 3.       NOTICE OF TERMINATION OF ORIGINAL TERM BY EMPLOYEE.
On or before the last day of the second year of the Original Term and assuming
that this Agreement has not been earlier terminated or entered upon the Phase
II Term (all as hereinafter provided), the Employee may give written notice to
UST and USTC of termination, whereupon all the provisions of this Agreement
will terminate (except as noted below in this Section 3) on the last day of the
Original Term.  If there has been a material breach of this Agreement by
Employee at any time during the Original Term or any Renewal Term, and the
arbitration under Section 18 hereof has confirmed that a material breach has
been committed by the Employee and such breach is uncured during the applicable
grace period, then the Employee will be subject in full to all of the
restrictions of Section 12, 13 and 14 hereof for the remainder of the
applicable term plus 90 days.  However, should the Employee terminate this
Agreement without a material breach at the end of the Original Term or at the
end of any Renewal Term, Sections 12, 13 and 14 of this Agreement shall not
apply.  Notwithstanding the foregoing, should the Employee terminate this
Agreement as described in either of the immediately preceding two sentences,
UST and USTC will retain all of their respective common law rights against the
Employee with respect to confidentiality, protection of customer lists, trade
secrets, non-competition and similar matters.

         SECTION 4.       PHASE II TERM.  If a Triggering Event occurs during
the Original or a Renewal Term, any such term shall automatically terminate and
the Phase II Term shall commence as of the earlier of the date of signing of a
definitive merger or acquisition agreement or the date of occurrence of such
Triggering Event.  The Phase II Term shall be for a period of three years from
the Closing Date under such definitive merger, consolidation or acquisition
agreement, or the date of the agreement related to any other such Triggering
Event, but in no event for longer than four years from such signing date, and
shall be terminable in the same manner as the Original





                                       3
<PAGE>   4
Term under Section 3 above (the "Phase II Term"). The "Closing Date" shall mean
the date on which the merger or consolidation becomes effective, the
acquisition is consummated or the change in corporate ownership related to any
other such Triggering Event takes effect. If the revenues of the AM business
decline precipitously and the Formula Payment described in Section 11 below
would be less than $3 Million, then the Employee may decline to accept the
Formula Payment and the Phase II Term.  If the AM revenues likewise decline,
and the Formula Payment described in  Section 11 below would be less than $5
Million, the Employee/Principal may elect to reduce the Phase II Term by one
year.

         SECTION 5.       TERMINATION BY EMPLOYEE FOR BREACH OF "INDEPENDENCE
ASSURANCES."  In the event of the material breach by UST or USTC (or their
respective successors) of any one or more of the "Independence Assurances"
listed below, the Employee/Principals, acting in accordance with the Unifying
Agreement, shall have the right (subject to compliance with Section 18 hereof)
but not the obligation, upon 30 days prior written notice to UST and USTC, to
terminate this Agreement.

         (a)     "Independence Assurances" shall consist of UST's and USTC's
non-interference (unless requested by the Employee/Principals of AM acting in
accordance with the Unifying Agreement) in the following:

                 (i)  The Employee/Principals control of AM's investment
philosophy and investment approach, business strategy, conduct of investment
analysis, portfolio selection, marketing, client retention and acceptance of
new clients, and client service;

                 (ii)  Authority of the Employee/Principals to hire and fire AM
personnel within the scope of UST's "Policies" (as hereinafter defined) and
applicable Federal and Massachusetts laws, subject to UST's right to approve
any person chosen by the Employee/Principals as the Senior Principal of AM,
which person shall also serve initially (i) as the Chief Executive Officer of
USTC, and (ii) on USTC Board of Directors.  UST, as sole shareholder of USTC,
subject to the terms of the Unifying Agreement and this Agreement, will at all
times retain the right to select a Chief Executive Officer of USTC who is not
an employee of AM.  USTC will not, however, select the Senior Principal;

                 (iii)  The Employee/Principals' authority to set AM client
fees based on their judgment concerning the market for services rendered by AM;

                 (iv)  The Employee/Principals' authority to establish AM's
operating expense budget and compensation practices, limited by "AM's Share of
Revenues" as provided in Section 10 (See Schedule V for example); and limited
further with respect to total cumulative cash incentive compensation for
Employee/Principals in the aggregate accrued in each of the years ending
December 31, 1994 and December 31, 1995, to $1.3 million plus incentive
compensation accrued in 1993 (it being understood





                                       4
<PAGE>   5
that the Formula Payment is not to be regarded as cash incentive compensation
for any purposes);

                 (v)    The Employee/Principals' authority to add and delete
Employee/Principals of AM in accordance with the Unifying Agreement; and

                 (vi)   The recognition by UST and USTC that AM, in pursuit
of its "socially-sensitive" investment objectives, may take some public
positions which may not represent the views of UST or USTC management.  The
Employee, however, recognizes that Employee's actions will remain subject to
the provisions of the Code of Ethics, Employment Policies, and certain other
key corporate policies of UST and USTC listed on and attached to Schedule II
hereto ("Policies"), as revised from time to time on a company-wide basis in
the ordinary course of UST's and USTC's business (which revisions shall be made
available to Employee at UST's principal office in Boston); and applicable
Federal and Massachusetts laws, regulations, policies, orders or understandings
in use by or applicable to UST and USTC.

         (b)     In the event that any of the "Independence Assurances" have
been  materially breached and not cured pursuant to Section 18, the Employee
may act either individually or in concert with any other Employee/Principal or
Employee/Principals or other employees so as to constitute a "person" as
defined in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the
"Exchange Act"), in electing to terminate their Employment Agreements, e.g.
they may collectively decide to give five (5) days notice and leave USTC to
form a new business which may directly compete with AM's business and Sections
12, 13 and 14 of this Agreement will not apply.

         SECTION 5A.      OVERSIGHT FUNCTION OF USTC'S BOARD OF DIRECTORS.
USTC's Board of Directors (a majority of whom shall not be Employee/Principals)
shall continue to exercise its oversight function of the business activities of
AM.  In performing such oversight function, USTC's Board the Directors will
assure itself that AM's business and operations are being conducted in a manner
consistent with applicable law and regulations, and such Board will be expected
to meet its fiduciary responsibilities to USTC and its depositors, and to UST,
in all respects, including without limitation, the prevention of corporate
waste of assets and taking steps to see that AM's business is operated with
their respective best interests in mind.  If in performing such oversight
function, the Board causes UST or USTC to breach an Independence Assurance and
such breach is (a) confirmed by the arbitrator under Section 18 or not
contested by UST or USTC and (b) not cured within the applicable grace period,
the Employee may terminate this Agreement and the Employee will leave with the
rights described in Section 5(b) of this Agreement.

         SECTION 6.       MATTERS NOT CONSTITUTING "INDEPENDENCE ASSURANCES".
The following shall specifically not be considered as "Independence Assurances"
but shall nevertheless govern the relationship by and among UST, USTC and AM:





                                       5
<PAGE>   6
         (a)     The location of AM's business for a period of three years from
January 1, 1995 on two floors at 40 Court Street, Boston, MA.  The Employee and
the other Employee/Principals shall cause AM to give twelve months written
notice of termination of such occupancy, if they so elect, no earlier than
December 31, 1996.  "Fair Rental" shall be charged or allocated by UST or USTC
for AM's premises, and UST or USTC shall give AM "high priority" with respect
to remodeling and upgrading of space.

         (b)     Matters covered in a Memorandum dated September 14, 1994 on
"Capital Expenditures/Intercompany Charges" which is attached as Schedule VI
hereto.

         (c)     The taking of reasonable steps by the Employee and the other
Employee/Principals to cause that appropriate levels of profit from AM's
business to be reinvested in the business (infrastructure, systems, facilities,
product development, compensation to staff members who are not Principals,
additional staff) during the Total Term (as hereinafter defined).  For the year
1995, the amount considered "appropriate" would be the investment of
approximately five percent (5%) of "Base Annual Revenues of AM" as defined in
Section 10.

         (d)     The amortization of AM capital expenditures over a period in
accordance with UST's and USTC's then current policy to the extent it is
consistent with GAAP.  In connection with the foregoing capital expenditures,
at the reasonable request of AM funding will be provided by UST and/or USTC
which will charge AM a fair interest rate for the cost of capital employed.
(See also Schedule VI).

         (e)     The providing of such information as is reasonably necessary
for UST to manage its affairs and responsibilities subject to client
confidentiality, including but not limited to information necessary to comply
with generally accepted accounting principles ("GAAP") in the preparation of
financial statements, budgets and profit plans, and for shareholder
communications, and responses to regulatory requests.

         (f)     The actions of all Employee Principals shall remain subject,
without limitation, to the terms of UST's Code of Ethics, the Payment Approval
Policy and the other Policies set forth in Schedule II hereto.

         SECTION 7.   TERMINATION OF EMPLOYMENT BY USTC.

         (a)     Employee's employment may be terminated by USTC (by majority
vote of its Board of Directors) in the following circumstances:

                 At any time after due notice and reasonable opportunity to
                 correct such conduct, (i) in the event of Employee's material
                 breach of any of the terms of this Employment Agreement; (ii)
                 in the event of Employee

                 causing a material breach of any of the other
                 Employee/Principals' duties to UST and USTC under Section 10
                 (Revenue Sharing Provision ); (iii) in the event of Employee's
                 willful misconduct in the performance of the Employee's duties
                 hereunder including, without limitation, but subject to
                 Sections 5 and 6 hereof, Employee's willful refusal to carry
                 out any "proper direction" by USTC's Board of Directors with
                 respect to the services to be rendered by Employee hereunder
                 or the manner of rendering such services; or (iv) in the event
                 of Employee's conviction of a crime involving moral turpitude.
                 The term "proper direction" as used in clause (iii) above, may
                 not be used in connection with an instruction, direction or
                 order which would cause UST or USTC to violate an
                 "Independence Assurance".

         (b)     In the event of Employee's death during the term of
employment,  unless otherwise determined by the Employee/Principals acting
pursuant to the Unifying Agreement, USTC's and UST's obligations to pay further
compensation hereunder shall cease as of the date of death, except that any
amounts due under Section 11 hereof or otherwise owed to Employee under welfare
or benefit plans or for deferred compensation and any amounts heretofore
accrued under Sections 3.1 and 3.2 of the Unifying Agreement, shall be paid
when due to the Employee's estate or named beneficiary.

         SECTION 8.       OFFICE AND DUTIES.  During the Original Term, any
Renewal Term, and the Phase II Term, if any, (hereinafter the "Total Term"),
Employee shall hold such positions and perform such duties relating to AM's
business and operations as are described on Schedule I hereto, and as may
otherwise from time to time be assigned to Employee by the Employee/Principals
consistent with all of the terms of this Agreement.  During the Total Term and
while employed by USTC, Employee shall devote (except as noted on Schedule I)
substantially all of Employee's business time to the Employee's duties
hereunder and shall, to the best of Employee's ability, perform such duties in
a manner which will faithfully and diligently further the business and
interests of AM.

         At any time while employed by USTC, Employee shall not directly or
indirectly solicit the business of any Past, Present, or Potential Clients (as
hereinafter defined) except on behalf and for the benefit of AM, or pursue any
other business activity, including, without limitation, serving as an officer,
director, employee, or adviser to any business entity other than AM, without
UST's and USTC's prior written consent; provided, however, that Employee may
without such consent, render without compensation investment advisory services
to immediate members of Employee's family, which shall include the Employee and
any trust or account which is comprised entirely of assets held for the benefit
of such Employee and/or immediate members of Employee's family, and may be
involved in such additional activities without such consent as are listed on
the Schedule I hereto.  Employee agrees to travel to whatever





                                       7
<PAGE>   8
extent is reasonably necessary in the conduct of AM's business.  Except when
engaged in such travel, Employee's place of employment shall be in the greater
Boston area of Massachusetts unless otherwise agreed to by Employee, UST and
USTC, and the Employee/Principals acting in accordance with the Unifying
Agreement.

         The term "Past Client" shall mean at any particular time any person or
entity who within three years prior to such time had been but at such time is
not an advisee, investment advisory customer, or client of AM.

         The term "Present Client" shall mean at any particular time any person
or entity who is at such time an advisee, investment advisory customer, or
client of AM.

         The term "Potential Client" shall mean at any particular time any
person or entity to whom AM, through any of the Employee/Principals or other of
its employees, has within three years prior to such time offered (by means of a
personal meeting, telephone call, or a letter or a written proposal
specifically directed to the particular person or entity) to serve as
investment adviser but who is not at such time an advisee or investment
advisory customer or client of AM.  The preceding sentence is meant to exclude
form letters and blanket mailings.

         The terms "Client" or "Client List" when used herein shall mean all
Past, Present, and Potential Clients as heretofore defined.  The term "Client"
when used in this Employment Agreement with respect to wrap accounts, shall
mean the wrap sponsors and the brokers employed by such wrap sponsors but not
the underlying wrap account holders.

         SECTION 9.     BENEFITS.  Employee shall participate, to the extent
Employee is eligible and in a manner and to an extent that is fair and
appropriate in light of the position and duties granted to Employee hereunder,
in all pension, profit-sharing, group insurance, or other fringe benefit plans
(other than UST corporate stock compensation plans) which UST or USTC may
hereafter in their absolute discretion make available generally to employees of
AM, but neither UST nor USTC will be required to establish any such program or
plan.  Employee shall be entitled to such vacations and to reimbursement of
such expenses as UST's or USTC's policies allow to all employees having
comparable responsibilities and duties.  So long as such additional benefits
are payable out of or accrue to "AM's Share of Revenues" as hereinafter
defined, the Employee/Principals may provide additional executive benefits to
themselves in addition to those provided by UST, provided that no such benefit
be qualified under Section 401 of  the Internal Revenue Code or non-qualified
(under Section 401 of the Internal Revenue Code) pursuant to the terms of a
plan or arrangement which operates in a manner that is substantially similar or
mirrors a qualified plan, and provided further that the award of any such
benefits does not increase the cost to UST of providing benefits to UST
employees who are not employees of AM.

         SECTION 10.      REVENUE SHARING PROVISION.  The purpose of this
Revenue Sharing Provision is to provide UST with an acceptable stream of income
and to permit AM to retain a specified percentage of its revenues for use by
Employee/Principals, including the Employee, in their discretion in paying
expenses of operation, including compensation.  It is intended to allow the
Employee and the other Employee/Principals to be compensated for enhancing and
growing AM's revenues in a substantial manner and to make operating decisions
freely within the limits of "AM's Share of Revenues," as such term is defined
below.  See Schedule V for examples of Revenue Sharing calculations.

         (a)     ALLOCATION OF REVENUES.  "Base Annual Revenues of AM" in 1994
and all subsequent years for purposes of this Revenue Sharing Provision shall
be AM's actual 1994 Revenues less $750,000, such total amount to be
appropriately modified to reflect changes in the United States Bureau of Labor
Statistics Cost of Living Index for the Boston Metropolitan Statistical Area or
any designated successor index for 1995 and all subsequent years.  The term
"Revenues" shall mean AM's revenues calculated on an accrual basis in
accordance with GAAP, (excluding shared revenues paid to investment or other
firms or professionals and generated from AM clients), consistent with USTC's
usual practice.

         During the pro-rated six month period commencing July 1, 1994 and
         ending December 31, 1994, and for each calendar year and for portions
         thereof on a pro-rated basis thereafter, AM shall retain sixty percent
         (60%) ("Base AM Retention"), of AM's pro-rated actual Revenues and AM
         shall make available to USTC for distribution to UST forty percent
         (40%) ("Base UST Amount"), subject to adjustment as set forth in this
         Section 10(a).

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar of AM's annual revenues
         over Base Annual Revenues of AM, AM shall retain an additional $.40,
         and an additional $.60 shall be allocated to UST, provided that in no
         event shall UST's Share of Revenues exceed fifty percent (50%) of
         actual Annual Revenues of AM.

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar that actual Annual
         Revenues of AM are less than Base Annual Revenues of AM, Base AM
         Retention shall be reduced by $.40 and the Base UST Amount shall be
         reduced by $.60, provided that in no event shall  UST's Share of
         Revenues be less than thirty percent (30%) of Annual Revenues of AM.

         Amounts retained by AM as aforesaid are herein referred to as "AM's
Share of Revenues".  Amounts allocated to UST as aforesaid are herein referred
to as "UST's Share of Revenues".





                                       9
<PAGE>   10
         (b)     FLOOR INCENTIVE.  In addition, during the Original Term of
this Agreement (thirty months), AM shall retain a "Floor Incentive" of $40,000
per month from "UST's Share of Revenues" ($1.2 million in the aggregate).  The
"Floor Incentive" shall be accrued by USTC and paid pursuant to subsection
(d)(iv) hereof, and shall be excluded from the limitations of Section 5(a)(iv)
of this Agreement.  In the event of a material breach by UST or USTC of this
Agreement during the Original Term (which breach is not cured during the
applicable grace period and is either confirmed by the arbitrator under Section
18 hereof or not contested by UST or USTC), the Employee/Principals (for
distribution in accordance with the Unifying Agreement) may elect to receive an
aggregate lump-sum payment determined by multiplying (x) the monthly "Floor
Incentive" by (y) the remaining months in the Original Term.  If a "Triggering
Event" occurs during the period January 1, 1995 through June 30, 1998, the
aggregate Floor Incentive, net of tax, accrued during the four full calendar
quarters next preceding the date of the Triggering Event, shall not be deducted
from "AM's After Tax Revenues" for purposes of calculating the Section 11
Formula Payment.  Moreover, if a Triggering Event occurred before all Floor
Incentives have been paid, UST or USTC's successor shall assume responsibility
to make the remaining Floor Incentive payments.

         (c)     SPECIAL PROVISIONS.  It is understood and agreed that:

                 (i)      The balance of "Base AM Retention" for the period
                          July 1, 1994 through December 31, 1994 shall be paid
                          by UST or USTC to AM no later than February 15, 1995.

                 (ii)     All amounts due to Robert B. Zevin pursuant to his
                          agreement dated September 30, 1994 with USTC shall be
                          considered as expenses to come out of "AM's Share of
                          Revenues" in each year in accordance with the
                          Unifying Agreement.

                 (iii)    The application of this Section may make it
                          unattractive for AM to enter a business activity with
                          a profit margin of less then 40%.  Accordingly, the
                          parties have agreed to negotiate separate "side
                          letters" with respect to revenue sharing on any new,
                          lower-margin business opportunities identified in the
                          future by AM and regarded as worthy of pursuit by UST
                          and/or USTC.

                 (iv)     The parties hereto further understand and acknowledge
                          that the term "Revenues" as used herein is intended
                          to cover revenues of AM as they now exist and as they
                          may grow or contract internally, and not revenues
                          from the acquisition by UST or USTC of another
                          investment advisory firm concerning which the parties
                          hereto agree to negotiate in good faith as to revenue
                          sharing.

                 (v)      The investment return on allocated, but unexpended,
                          portions of AM's Share of Revenues shall be measured
                          at the end of each calendar quarter by multiplying
                          the average of the month end balances during such
                          quarter by the published thirteen week U.S. Treasury
                          Bill Rate at the end of such calendar quarter.This
                          interest income shall be added to "AM's Share of
                          Revenues".

         (d)     TRANSFER OF REVENUES TO UST; RETENTION OF REVENUES BY
                 USTC;COMPENSATION OF EMPLOYEE/PRINCIPALS.

                 (i)      The Employee/Principals and AM shall use AM's Share
                          of Revenues to pay and provide for AM's business
                          expenses and expenditures including, without
                          limitation, investment in AM's business and new
                          products (see Section 6(d) above) and salaries of its
                          employees, except that any federal, state or local
                          income tax to which USTC is subject shall be the
                          responsibility of UST and shall not be treated as a
                          business expense of AM.

                 (ii)     The Employee/Principals shall incur no expenses or
                          obligations on behalf of AM which exceed USTC's
                          ability to pay or provide for them when due out of
                          AM's Share of Revenues.  The Employee/Principals
                          shall not incur obligations or make binding
                          commitments on behalf of USTC or UST not related to
                          AM's business and requiring expenditures by USTC in
                          excess of $50,000, or make representations to third
                          parties that they have the authority to do so.
                          However, the Employee/Principals may represent and
                          advertise that AM is a division of USTC and an
                          affiliate of UST, and other than as limited above in
                          this Section 10 (d)(ii), may incur obligations or
                          make binding commitments on behalf of USTC in the
                          ordinary course of business.

                 (iii)    The Employee/Principals may (subject to Policies and
                          applicable laws and regulations) pay to AM's
                          employees, including the Employee and the other
                          Employee/Principals, at times and in amounts and
                          proportions determined in accordance with the
                          Unifying Agreement, the balance of AM's Share of
                          Revenues remaining after the payment of all of the
                          amounts required under subsection (d)(i) hereof and
                          subject to Section 5(a)(iv).

                  (iv)    The Employee's Revenue Sharing compensation out of
                          "AM's Share of Revenues" shall be allocated in
                          accordance with the terms of the Unifying Agreement.
                          The Employee/Principals have provided to UST and USTC
                          in the Unifying Agreement their procedures for
                          determining changes, if any, in the allocation of





                                       11
<PAGE>   12
                          Revenues among the Employee/Principals.  If an
                          Employee/Principal chooses to leave USTC's employ
                          after bypassing this change determination mechanism
                          or refusing to abide by its results, the
                          Employee/Principal shall be deemed to have committed
                          a material breach of this Employment Agreement.

                 (v)      The Employee/Principals and AM shall make available
                          to UST, UST's Share of Revenues upon reasonable
                          request by UST and action by USTC's Board of
                          Directors.  The Employee/Principals shall not spend
                          or incur obligations to spend any part of UST's Share
                          of Revenues.

         (e)     ADMINISTRATION.  The parties hereto and the other
Employee/Principals agree to meet and consult to endeavor in good faith to
agree on appropriate procedures, in addition to Policies and applicable laws
and regulations,  for administering the provisions of this Section 10.

         The Employee/Principals shall retain control over all expenditures of
AM, subject to the power of USTC's Board of Directors to exercise its rights
under Section 5A, and subject to this Revenue Sharing Provision, and
recognizing that AM is a division of USTC.

         (f)     TERM AND STATUS AS PARTIES.  This Revenue Sharing Provision
shall continue in effect until terminated by agreement of UST, USTC, and the
Employee/Principals acting in accordance with the Unifying Agreement.  If the
employment of Employee by USTC ceases other than as a result of a material
breach by UST or USTC of this Employment Agreement, such Employee shall
thereupon automatically cease to be a party to this Revenue Sharing Provision
and to have any rights or obligations under this Section, and shall cease to be
an Employee/Principal for the purposes of this Provision.  Nothing  in this
Employment Agreement shall be construed to grant to the Employee any right to
be employed by USTC beyond the terms of this Employment Agreement.

         SECTION 11.      FORMULA PAYMENT.  If Employee is still employed by
USTC at the time of a "Triggering Event" (as hereinafter defined), the Employee
shall receive Employee's share of a formula payment (the "Formula Payment") as
follows:

         (a)     Unless otherwise agreed by the Employee/Principals acting in
accordance with the Unifying Agreement, the Employee's share of the Formula
Payment shall be the percentage set forth after the Employee's name on Schedule
III hereto;

         (b)     The "Formula Payment" shall be 3.33 times "AM's After Tax
Revenues" (as hereinafter defined and meaning generally UST's Share of Revenues
minus taxes);





                                       12
<PAGE>   13
         (c)     "AM's After Tax Revenues" shall be the portion of AM's
after-tax Revenues contributed, accruing or allocated to UST for the four full
calendar quarters next preceding the date of the Triggering Event; determined
in accordance with GAAP consistently applied in such periods.  For purposes of
this Subsection, there shall be assumed a combined federal and state tax rate
of 38%, such rate to be appropriately adjusted to reflect changes in applicable
federal and state corporate tax rates.  An example of this calculation is set
forth on Schedule V.

         (d)     The Formula Payment shall be adjusted in accordance with
Schedule IV hereto for gain or loss of AM clients between the signing of a
definitive merger, consolidation or acquisition agreement or an agreement
related to another Triggering Event and the Closing Date related to any such
Triggering Event.

         (e)
                 (i)      At the Closing Date of a Triggering Event, three Key
                          Employees shall be identified as follows.  For every
                          person who has been an Employee/Principal at any time
                          during the previous 15 months there shall be
                          calculated a Weighted Average Share equal to the sum
                          of (a) the share of the Formula Payment such person
                          was entitled to receive from time-to-time during the
                          preceding 15 months in accordance with Schedule III
                          and subsequent changes thereto by the
                          Employee/Principals acting in accordance with the
                          Unifying Agreement times (b) the number of days such
                          person was entitled to each such share.  The three
                          persons among those who are or have been
                          Employee/Principals on the Closing Date of the
                          Triggering Event or during the previous 15 months who
                          have the three highest Weighted Average Shares shall
                          be deemed the "Key Employees".

                 (ii)     If only one of the three Key Employees is no longer
                          in the employ of USTC as of the Closing Date of such
                          Triggering Event, then all of that Key Employee's
                          Weighted Average Share of the Formula Payment
                          (expressed by X%) shall be placed in escrow in the
                          manner contemplated by Section 11(f). To determine
                          the distribution of each of the three escrowed
                          installments use the following formula.  Revenues of
                          AM (as defined in Section 10(a)) for the last full
                          calendar year prior to a Triggering Event should then
                          be determined (the "Measuring Year").  Such Revenues
                          of AM for the Measuring Year multiplied by a decimal
                          representing 100% - X% equals the "Minimum Revenues".
                          If during the next full calendar year following the
                          Measuring Year, Revenues of AM are equal to or less
                          than Minimum Revenues none of the one-third of the
                          escrowed amount for such year will be paid to the
                          remaining Employee/Principals in accordance with this
                          Section and all of it will be retained by UST's or
                          USTC's successor.  If Revenues of AM for





                                       13
<PAGE>   14
                          that calendar year exceed Minimum Revenues, (i) take
                          the U.S. Dollar amount of such excess above the
                          Minimum Revenues and divide it by the Revenues of AM
                          for the Measuring Year minus the Minimum Revenues,
                          (ii) then multiply the resulting fraction by
                          one-third of the full escrowed amount, (iii) the
                          product of the foregoing formula should be delivered
                          to the remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and the remainder of that installment
                          should be retained by UST or UST's successor.
                          Similar calculations should be made for the second
                          and third installments, but in each case using the
                          same Minimum Revenues.

                 (iii)    If two or more of the Key Employees are no longer in
                          the employ of USTC as of the Closing Date of such
                          Triggering Event, then 100% of the Formula Payment
                          shall be placed in escrow in the manner contemplated
                          by Section 11(f).  To determine the distribution of
                          each of the three escrowed installments use the
                          following formula.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment equal or exceed
                          Revenues of AM for the Measuring Year, all of that
                          escrowed installment should be distributed to the
                          remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and none should be retained by UST or
                          USTC's successor.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment are less than
                          Revenues of AM for the Measuring Year, divide the
                          U.S. Dollar amount of Revenues of AM for such last
                          full calendar year by the U.S. Dollar amount of
                          Revenues of AM for the Measuring Year and multiply
                          the resulting fraction by one-third of the full
                          escrowed amount.  The product of the foregoing
                          calculation should be delivered to the remaining
                          Employee/Principals as a group for distribution in
                          accordance with the Unifying Agreement and the
                          remainder should be retained by UST's or USTC's
                          successor.

         (f)     Seventy percent (70%) of the Employee's share of the Formula
Payment shall be paid in cash within twenty (20) days of the Closing Date of
the Triggering Event.  The remaining thirty percent (30%) shall be placed in
escrow with an escrow agent acceptable to both UST and Employee/Principals and
paid to the Employee or the Employee's estate as provided in Section 7(b) in
installments of one third of the escrowed amount at the end of years one, two
and three (which may not be calendar years) after the Closing Date of the
Triggering Event plus interest, at the interest rates on the date of the
Closing Date of the Triggering Event of one, two and three year Treasury
securities,  provided that at the time of each such installment payment, the
Employee has not been terminated with cause or for a material breach or has not
voluntarily ceased to be employed by AM.

         (g)     A "Triggering Event" shall be deemed to have occurred when:

                 (i)      there occurs the signing of a definitive agreement of
                          merger or consolidation of UST or USTC with any other
                          corporation, other than a merger or consolidation
                          which would result in the voting securities of UST or
                          USTC 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 USTC, or such surviving entity outstanding
                          immediately after such merger or consolidation;
                          provided, however, that a merger or consolidation
                          effected to implement a recapitalization,
                          reorganization or restructuring of UST or USTC (or
                          similar transaction) in which no "person" (as defined
                          in (g)(iii) below) acquires more than fifty percent
                          (50%) of the combined voting power of UST's then
                          outstanding securities shall not constitute a
                          Triggering Event; or

                 (ii)     there occurs a closing of a sale or other disposition
                          by UST of more than 50% of UST's, USTC's or AM's
                          business and assets; or

                 (iii)    any "person", as such term used in Section 13(d) and
                          14(d) of the Exchange Act other than UST or USTC or
                          any of their respective subsidiaries or affiliates or
                          any trustee or other fiduciary holding securities
                          under an employee benefit plan of either of them or
                          any of their subsidiaries or 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
                          50% percent or more of the combined voting power of
                          UST's or USTC's then outstanding securities.

         If (i) more than 50% of UST's then outstanding common stock or assets
are acquired by a "person" whose consolidated assets prior to the Triggering
Event were less than $4 billion or (ii) UST's business assets and operations
are consolidated with those of another bank or bank holding company and the
resulting entity has consolidated assets of $5.5 billion or less, a Triggering
Event shall be deemed to have occurred, but the length of the Phase II term of
employment of the Employee shall be increased automatically by one additional
year.

         (h)     If UST agrees to be acquired by an entity with a public image
so starkly negative that AM's affiliation with that entity would be reasonably
likely, by itself, to cause a loss of more than 25% of AM's gross revenues in
one year (unless the parties





                                       15
<PAGE>   16
mutually agree to the contrary), the Employee/Principals at their option acting
pursuant to the terms of the Unifying Agreement (and provided such right is
exercised within 30 days of the public announcement of such acquisition) will
be relieved of all of the Employee's obligations under the Phase II Term and no
Formula Payment will be made.

         (i)     The parties acknowledge that any such Formula Payment is
intended to compensate the Employee for: (i) the automatic extension of this
Agreement occurring by reason of a Triggering Event; (ii) the Phase II
Non-Competition covenants specified in Section 12; and (iii) the loss of
opportunity to make up for reduced rate of compensation which such Employee
earned with USTC for periods prior to the effective date of this Agreement.

         SECTION 12.      PHASE II NON-COMPETITION COVENANTS.

         (a)     During the longer of the Phase II Term (as defined in Section
4) if Phase II shall commence while Employee is employed by USTC hereunder or
while Employee is employed by USTC during or after such Phase II Term
hereunder, Employee shall not, except in the course of his employment with
USTC, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, stockholder,
                          consultant, adviser, subsidiary, affiliate,
                          independent contractor or otherwise, investment
                          advisory services to any person or entity;

                 (ii)     Interfere with AM's relations with any person or
                          entity who at any time during such period was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person, other than by
                          discharge of such person as a part of Employee's
                          duties.

         (b)     Until one year following the end of the Phase II Term, if the
Phase II Term should commence while Employee is employed by USTC hereunder or
one year following the termination of Employee's employment with USTC during or
after such Phase II Term, Employee shall not, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, independent
                          contractor or otherwise, investment advisory services
                          to any person or entity who as of the date of the
                          termination or expiration of Employee's employment





                                       16
<PAGE>   17
                          with USTC was or had been a Client (which means Past,
                          Present, and Potential Client);

                 (ii)     Interfere with AM's relations with any person or
                          entity who as of the date of the termination or
                          expiration of Employee's employment with USTC was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person.

         (c)     Notwithstanding the provisions of subsections (a)(i) and
(b)(i), the Employee may render without compensation investment advisory
services to any immediate member of Employee's family, which shall include the
Employee and any trust or account which is comprised entirely of assets held
for the benefit of such Employee and/or immediate members of such Employee's
family, and may engage in such other activities as are listed on Schedule I
hereto.

         (d)     Employee and USTC agree that the periods of time and the
unlimited geographic area applicable to the covenants of this Section 12 are
reasonable, in view of the receipt and expected receipt of the Employee's share
of Revenue Sharing as provided in Section 10(c), and other compensation, and
the Formula Payment provided herein; the geographic scope and nature of the
business in which AM is engaged; Employee's knowledge of AM's business; and
Employee's relationships with AM's investment advisory clients.  However, if
such period or such area should be adjudged unreasonable in any judicial
proceeding, then the period of time shall be reduced by such number of months
or such area shall be reduced by elimination of such portion of such area, or
both, as are deemed unreasonable, so that this covenant may be enforced in such
area and during such period of time as are adjudged to be reasonable.

         SECTION 13.      ALL BUSINESS TO BE THE PROPERTY OF USTC; ASSIGNMENT
OF INTELLECTUAL PROPERTY.  During the Phase II Term if Phase II shall commence
while Employee is Employed by USTC hereunder and thereafter while Employee is
employed by AM and/or USTC:

         (a)     Employee agrees that any and all presently existing investment
advisory business of AM and all business developed by Employee or any other
employee of AM, including without limitation all investment advisory contracts,
fees, commissions, compensation records, Client Lists (as defined in Section
8), agreements, and any other incident of any business developed or sought by
AM or earned or carried on by Employee for AM, are and shall be the exclusive
property of USTC for its sole use, and (where applicable) shall be payable
directly to USTC.





                                       17
<PAGE>   18
         (b)     Employee hereby grants to USTC (without any separate
remuneration or compensation other than that received by Employee from time to
time in the course of his or her employment) Employee's entire right, title,
and interest throughout the world in and to, all research, information, Client
Lists, and all other investment advisory, technical and research data made,
conceived, developed and/or acquired by Employee solely or jointly with others
during the period of Employee's employment by USTC, which relate to investment
advice as it was or is now rendered or as it may, from time to time, hereafter
be rendered or proposed to be rendered, but excluding such individual's ideas
and thought processes which are not embodied in written or machine readable
form (all such non-excluded items being referred to as "Intellectual
Property").

         SECTION 14.      CONFIDENTIALITY.  Except in performance of services
for USTC, Employee shall not, either during the Phase II Term if Phase II shall
commence while the Employee is employed by USTC hereunder or thereafter while
employed by AM and/or USTC, use for Employee's own benefit or disclose to or
use for the benefit of any person outside USTC, any information not lawfully
available to the public concerning any Intellectual Property, including Client
Lists, whether Employee has such information in his or her memory or embodied
in writing or other tangible form.  All such Intellectual Property and such
information concerning Intellectual Property, and all originals and copies of
any Intellectual Property, and any other written material relating to the
business of AM, shall be the sole property of USTC.  During such Term or
thereafter, upon the termination of Employee's employment in any manner or for
any reason, Employee shall promptly surrender to USTC all originals and copies
of any Intellectual Property, and Employee shall not thereafter use any
Intellectual Property.

         The foregoing notwithstanding, Employee will have no obligation to AM
or USTC with respect to the disclosure or use of any Intellectual Property or
information concerning Intellectual Property if:

         (a)  Such Intellectual Property or information is or becomes publicly
known or otherwise enters the public domain through no wrongful act of
Employee; or

         (b)  Such Intellectual Property or information is received from a
third party which has no obligation to UST or USTC to maintain it in
confidence.

         Notwithstanding the references to Client Lists above, it shall not be
a violation of this Section or Section 13 hereof for Employee to communicate or
do business with any Past, Present or Potential Client in the course of
Employee's employment with AM and USTC, and any such conduct shall be limited,
if at all, solely by Section 12 hereof.

respect to the subject matter hereof, and supersede all prior oral and written
agreements between any of UST, USTC, AM and the Employee with respect to the
subject matter hereof, including without limitation any oral agreements
relating to compensation.

         SECTION 18.      ARBITRATION.  In the event the parties hereto
disagree as to whether a material breach has occurred of: (i) the "Independence
Assurances" under Section 5; (ii) USTC's right of termination of Employee's
employment under Section 7; (iii) this Agreement by USTC as described in
Section 19 (b); (iv) the revenue sharing provisions of Section 10; or (v) the
formula payment provisions of Section 11, such dispute shall be settled by
arbitration before a single arbitrator to be then named by UST and a majority
of the Employee/Principals acting in accordance with the Unifying Agreement, in
Boston, Massachusetts in accordance with the Commercial Arbitration Rules of
the American Arbitration Association.  If such arbitrator cannot serve, then a
successor shall be appointed in accordance with such Rules.  If the arbitrator
finds that there has been a material breach (and such breach has not been cured
by UST or USTC within sixty (60) days of such finding or by Employee in
accordance with Section 7 hereof), then the remedies provided for in Section 19
shall become available, as appropriate.

         SECTION 19.      EQUITABLE RELIEF AND OTHER REMEDIES.

         (a)  Employee recognizes and agrees that UST's, USTC's or the
Employee/Principals' remedies at law for any breach of the provisions of
Sections 12, 13 and 14 hereof would be inadequate and that for breach of such
provisions UST, USTC and the Employee/Principals  shall, in addition to such
other remedies as may be available to any of them at law or in equity or as
provided in this Employment Agreement, be entitled to injunctive relief and to
enforce their respective rights by an action for specific performance to the
extent permitted by law, and to the right of set-off against any amounts due to
the Employee by UST, USTC or AM.  Should Employee engage in any activities
prohibited by this Employment Agreement, he or she agrees to pay over to USTC
or UST all compensation received in connection with such activities.  Such
payment shall not impair any other rights or remedies of UST, USTC or AM or
affect the obligations or liabilities of Employee under this Employment
Agreement or applicable law.

         (b)  Any termination by USTC of Employee's employment which is not
authorized by Section 7 hereof shall constitute a material breach of this
Agreement.  In the event of a material breach of this Agreement by UST or USTC
which is not cured pursuant to Section 18, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, USTC
shall pay Employee the Employee's then current Annual Base Salary for a period
equal to the greater of (i) twelve months or (b) the balance of the then
current term of this Agreement.  Any such payments shall not constitute part of
AM's Share of Revenues.  Should such a material breach occur and not be so
cured, the Employee shall be  free to compete, Sections 12, 13 and 14 shall not
apply and the Employee shall leave with the rights described in Section 5(b) of
this Agreement.

         (c)  Without limiting the generality of the foregoing, the parties 
expressly agree





                                       20
<PAGE>   21
that termination without cause of Employee's employment hereunder during the
Phase II Term by UST, USTC or any other person or entity will constitute a
material breach of this Agreement and, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, shall
give Employee the right to salary continuation as set forth in Section 19(b)
hereof.

         SECTION 20.      WAIVERS AND FURTHER AGREEMENTS.  Neither this
Employment Agreement nor any term or condition hereof, including without
limitation the terms and conditions of this Section 20, may be waived in whole
or in part as against UST, USTC, AM or Employee except by written instrument
executed by each of them, expressly stating that it is intended to operate as a
waiver of this Employment Agreement or the applicable term or condition hereof.
Each of the parties hereto agrees to execute all such further instruments and
documents and to take all such further action as the other party may reasonably
require in order to effectuate the terms and purposes of this Employment
Agreement as stated herein.  Furthermore, no waiver may violate the terms of
the Unifying Agreement and any waiver shall require action of the
Employee/Principals in accordance with the Unifying Agreement authorizing such
waiver.

         SECTION 21.      AMENDMENTS.  This Employment Agreement may not be
amended, nor shall any parties be added hereto, nor any change, modification,
consent, or discharge be effected except by written instrument executed by all
three of the Employee, USTC and UST.  Furthermore, no amendment or modification
may violate the terms of the Unifying Agreement and any amendment or
modification shall require action of the Employee/Principals in accordance with
the Unifying Agreement authorizing such amendment or modification.

         SECTION 22.      SEVERABILITY.  If any provision of this Employment
Agreement shall be held or deemed to be invalid, inoperative or unenforceable
in any jurisdiction or jurisdictions, because of conflicts with any
constitution, statute, rule or public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision in question
unenforceable in any other jurisdiction or in any other case or circumstance or
of rendering any other provisions herein contained unenforceable to the extent
that such other provisions are not themselves actually in conflict with such
constitution, statute or rule of public policy, but this Employment Agreement
shall be reformed and construed in any such jurisdiction or case as if such
invalid, inoperative, or unenforceable provision had never been contained
herein and such provision reformed so that it would be enforceable to the
maximum extent permitted in such jurisdiction or in such case.

         SECTION 23.      NO CONFLICTING OBLIGATIONS.  Employee represents and
warrants to USTC and UST that Employee has no other interest or obligation
which is inconsistent or in conflict with this Employment Agreement or which
would prevent, limit, or impair, in any way, Employee's performance of any of
the covenants or duties





                                       21
<PAGE>   22
hereinabove set forth.

         SECTION 24.      PARTIES.  It is understood and agreed that UST joins
in this Employment Agreement only as to such matters where its name appears
herein.  It is further understood and agreed that no person shall participate
in the benefits conferred on Employee/Principals by the terms of this and other
similar Employment Agreements unless such person has become a party to a
similar Employment Agreement or is described in Section 16.

         SECTION 25.      GOVERNING LAW.  This Employment Agreement shall be
governed by and construed and enforced in accordance with the laws of the
Commonwealth of Massachusetts which apply to contracts executed and performed
solely in Massachusetts.  UST, USTC and the Employee hereby consent to the
jurisdiction of any state or federal court located within Suffolk County,
Massachusetts, and assent that service of process may be made by registered
mail to the parties' respective addresses as provided in Section 15 hereof and
shall be effective in the same manner as notices are effective under such
Section 15.

         SECTION 26.      ACTION OF THE EMPLOYEE/PRINCIPALS.  Whenever the
Consent of the Employee/Principals shall be described herein, action by the
Employee/Principals or their duly authorized representative shall be required
in accordance with the Unifying Agreement, and such action shall be sufficient
hereunder.

         IN WITNESS WHEREOF, the parties have executed this Employment
Agreement as a sealed instrument as of the date first above written.

                                                           EXHIBIT 10(y)(iv)

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

         AGREEMENT made as of February 14, 1995 and effective January 1, 1995
between United States Trust Company ("USTC"), a banking and trust company
having its principal place of business in Boston, Massachusetts, and joined in
as to certain matters by UST Corp. ("UST"), a Massachusetts corporation also
having its principal place of business in Boston, Massachusetts and the parent
of USTC; and Lucia B. Santini (the "Employee").

                                  BACKGROUND
                                  ----------

         The Employee and the other principals of the Asset Management Division
of USTC ("AM") listed on Schedule I hereto and such other principals as may be
added pursuant to the Unifying Agreement (as hereinafter defined) (all such
employees, while they remain principals, being referred to herein from time to
time as "Employee/Principals") are concerned that previous UST and USTC
practices have not allowed for enough spending to generate growth in AM's
business, or for fully competitive compensation for its principals; want
assurances of continued freedom to manage the AM business; want to participate
in an incentive compensation program which reflects the value created in this
business; and want to make it attractive to any potential acquirer of UST, USTC
or AM to (i) protect existing relationships with AM employees and clients, (ii)
avoid re-writing existing client contracts, and (iii) further AM as a separate
business conducted under the name "United States Trust Company".

         UST and USTC want to stabilize and increase the profitability of AM;
pay competitive compensation; provide incentive compensation reflecting the
growth in the business of AM; and (in the event of a "Triggering Event" as
hereinafter defined) offer an opportunity to a prospective purchaser to retain
the services of Employee and the other Employee/Principals and thereby receive
a continuing stream of profits from AM.

         UST and USTC recognize the importance of Employee to their business
and to USTC's ability to retain AM client relationships, and desire that USTC
employ Employee as an officer and principal of AM for the period of employment
and upon and subject to the terms herein provided.

         UST and USTC wish to be assured that Employee will not compete with
AM's business during the period of employment, and in certain circumstances and
as set forth below will not for a period thereafter solicit any Past, Present,
or Potential Clients (as hereinafter defined) of AM and will not by such
solicitation damage USTC's and AM's goodwill among its clients and the general
public.

                                      1
<PAGE>   2
         Employee desires to be employed by USTC and serve as an
Employee/Principal of AM and to participate in the incentive compensation
program contemplated by this agreement, and to refrain from competing with USTC
or AM or soliciting AM's clients for the periods and upon and subject to the
terms herein provided.

         Employee has been employed by USTC and AM for approximately 21 years;
has while so employed contributed to the acquisition and retention of AM's
clients, and will continue to seek to acquire and retain clients and to
generate goodwill for AM in the future as an officer and employee of USTC and
an Employee/Principal of AM for the periods and on the terms contemplated
hereby.

         When the terms "AM," "AM's business," or the "AM Division" are used
herein, such terms specifically exclude the non- investment advisory business
of USTC such as (1) the business of UST Capital Corp. (venture capital) and (2)
the management of USTC's internal securities portfolio.  Such terms, however,
include the investment return on allocated, but unexpended, portions of AM's
Share of Revenues as reflected on Schedule V. The investment return on
allocated, but unexpended, portions of AM's share of revenues shall be measured
at the end of each calendar quarter by multiplying the average of the month end
balances during such quarter by the published thirteen week U.S. Treasury Bill
Rate at the end of such calendar quarter and such interest income shall be
added to "AM's Share of Revenues".  All current Employee/Principals are listed
on Schedule I.

         Employee, the other Employee/Principals, UST and USTC have entered
into an agreement of even date herewith (the "Unifying Agreement") which
describes generally their agreements and certain procedures they have agreed to
follow among themselves.  This Employment Agreement is executed pursuant to and
in accordance with the terms of the Unifying Agreement.  Certain capitalized
terms used but not defined herein shall have the meanings given them in the
Unifying Agreement.

                                  AGREEMENTS
                                  ----------

         In consideration of the premises, the mutual covenants and the
agreements hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
covenant and agree as follows:

         SECTION 1.  ORIGINAL TERM OF EMPLOYMENT; COMPENSATION.  USTC
agrees to employ Employee for a period of two and one-half (2 1/2) years
beginning on the date hereof (the "Original Term") as an officer of USTC and an
Employee/Principal of AM; and Employee hereby accepts such employment.  USTC
will pay Employee for Employee's services during the Original Term, and any
Renewal Term (as hereinafter provided) and any Phase II Term, the Annual Base
Salary set forth on Schedule I hereto, and such additional annual incentive
payments as shall be determined by the 


                                      2
<PAGE>   3
Employee/Principals consistent with the Revenue Sharing Provision (Section 10
hereof), and subject to such payroll and withholding deductions as are
required by law.  Consistent with the Revenue Sharing Provision, the Employee's
total compensation will be reviewed at least annually in accordance with the
Unifying Agreement, having in mind that such compensation be fair and
reasonable in light of Employee's position and the duties to be performed by
the Employee and the Employee's efforts to enhance the business of AM.

         SECTION 2.  RENEWAL TERMS.  If no "Triggering Event" has occurred
and this Agreement has not been terminated by either party (all as hereinafter
provided) prior to the end of the Original Term, then the Original Term shall
be automatically extended for successive six month renewal terms (each referred
to herein as a "Renewal Term", or collectively as "Renewal Terms") until such
Triggering Event or termination has occurred, or until the Employee shall have
provided at least six months advance written notice to UST and USTC of election
not to enter a Renewal Term.

         SECTION 3.  NOTICE OF TERMINATION OF ORIGINAL TERM BY EMPLOYEE.
On or before the last day of the second year of the Original Term and assuming
that this Agreement has not been earlier terminated or entered upon the Phase
II Term (all as hereinafter provided), the Employee may give written notice to
UST and USTC of termination, whereupon all the provisions of this Agreement
will terminate (except as noted below in this Section 3) on the last day of the
Original Term.  If there has been a material breach of this Agreement by
Employee at any time during the Original Term or any Renewal Term, and the
arbitration under Section 18 hereof has confirmed that a material breach has
been committed by the Employee and such breach is uncured during the applicable
grace period, then the Employee will be subject in full to all of the
restrictions of Section 12, 13 and 14 hereof for the remainder of the
applicable term plus 90 days.  However, should the Employee terminate this
Agreement without a material breach at the end of the Original Term or at the
end of any Renewal Term, Sections 12, 13 and 14 of this Agreement shall not
apply.  Notwithstanding the foregoing, should the Employee terminate this
Agreement as described in either of the immediately preceding two sentences,
UST and USTC will retain all of their respective common law rights against the
Employee with respect to confidentiality, protection of customer lists, trade
secrets, non-competition and similar matters.

         SECTION 4.  PHASE II TERM.  If a Triggering Event occurs during
the Original or a Renewal Term, any such term shall automatically terminate and
the Phase II Term shall commence as of the earlier of the date of signing of a
definitive merger or acquisition agreement or the date of occurrence of such
Triggering Event.  The Phase II Term shall be for a period of three years from
the Closing Date under such definitive merger, consolidation or acquisition
agreement, or the date of the agreement related to any other such Triggering
Event, but in no event for longer than four years from such signing date, and
shall be terminable in the same manner as the Original 


                                      3
<PAGE>   4
Term under Section 3 above (the "Phase II Term"). The "Closing Date" shall mean
the date on which the merger or consolidation becomes effective, the
acquisition is consummated or the change in corporate ownership related to any
other such Triggering Event takes effect. If the revenues of the AM business
decline precipitously and the Formula Payment described in Section 11 below
would be less than $3 Million, then the Employee may decline to accept the
Formula Payment and the Phase II Term.  If the AM revenues likewise decline,
and the Formula Payment described in Section 11 below would be less than $5
Million, the Employee/Principal may elect to reduce the Phase II Term by one
year.

         SECTION 5.  TERMINATION BY EMPLOYEE FOR BREACH OF "INDEPENDENCE
ASSURANCES."  In the event of the material breach by UST or USTC (or their
respective successors) of any one or more of the "Independence Assurances"
listed below, the Employee/Principals, acting in accordance with the Unifying
Agreement, shall have the right (subject to compliance with Section 18 hereof)
but not the obligation, upon 30 days prior written notice to UST and USTC, to
terminate this Agreement.

         (a)     "Independence Assurances" shall consist of UST's and USTC's
non-interference (unless requested by the Employee/Principals of AM acting in
accordance with the Unifying Agreement) in the following:

                 (i)  The Employee/Principals control of AM's investment
philosophy and investment approach, business strategy, conduct of investment
analysis, portfolio selection, marketing, client retention and acceptance of
new clients, and client service;

                 (ii)  Authority of the Employee/Principals to hire and fire AM
personnel within the scope of UST's "Policies" (as hereinafter defined) and
applicable Federal and Massachusetts laws, subject to UST's right to approve
any person chosen by the Employee/Principals as the Senior Principal of AM,
which person shall also serve initially (i) as the Chief Executive Officer of
USTC, and (ii) on USTC Board of Directors.  UST, as sole shareholder of USTC,
subject to the terms of the Unifying Agreement and this Agreement, will at all
times retain the right to select a Chief Executive Officer of USTC who is not
an employee of AM.  USTC will not, however, select the Senior Principal;

                 (iii)  The Employee/Principals' authority to set AM client
fees based on their judgment concerning the market for services rendered by AM;

                 (iv)  The Employee/Principals' authority to establish AM's
operating expense budget and compensation practices, limited by "AM's Share of
Revenues" as provided in Section 10 (See Schedule V for example); and limited
further with respect to total cumulative cash incentive compensation for
Employee/Principals in the aggregate accrued in each of the years ending
December 31, 1994 and December 31, 1995, to $1.3 million plus incentive
compensation accrued in 1993 (it being understood

                                      4
<PAGE>   5
THAT the Formula Payment is not to be regarded as cash incentive compensation
for any purposes);

                 (v)  The Employee/Principals' authority to add and delete
Employee/Principals of AM in accordance with the Unifying Agreement; and

                 (vi)  The recognition by UST and USTC that AM, in pursuit
of its "socially-sensitive" investment objectives, may take some public
positions which may not represent the views of UST or USTC management.  The
Employee, however, recognizes that Employee's actions will remain subject to
the provisions of the Code of Ethics, Employment Policies, and certain other
key corporate policies of UST and USTC listed on and attached to Schedule II
hereto ("Policies"), as revised from time to time on a company-wide basis in
the ordinary course of UST's and USTC's business (which revisions shall be made
available to Employee at UST's principal office in Boston); and applicable
Federal and Massachusetts laws, regulations, policies, orders or understandings
in use by or applicable to UST and USTC.

         (b)     In the event that any of the "Independence Assurances" have
been  materially breached and not cured pursuant to Section 18, the Employee
may act either individually or in concert with any other Employee/Principal or
Employee/Principals or other employees so as to constitute a "person" as
defined in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the
"Exchange Act"), in electing to terminate their Employment Agreements, e.g.
they may collectively decide to give five (5) days notice and leave USTC to
form a new business which may directly compete with AM's business and Sections
12, 13 and 14 of this Agreement will not apply.

         SECTION 5A.  OVERSIGHT FUNCTION OF USTC'S BOARD OF DIRECTORS.
USTC's Board of Directors (a majority of whom shall not be Employee/Principals)
shall continue to exercise its oversight function of the business activities of
AM.  In performing such oversight function, USTC's Board the Directors will
assure itself that AM's business and operations are being conducted in a manner
consistent with applicable law and regulations, and such Board will be expected
to meet its fiduciary responsibilities to USTC and its depositors, and to UST,
in all respects, including without limitation, the prevention of corporate
waste of assets and taking steps to see that AM's business is operated with
their respective best interests in mind.  If in performing such oversight
function, the Board causes UST or USTC to breach an Independence Assurance and
such breach is (a) confirmed by the arbitrator under Section 18 or not
contested by UST or USTC and (b) not cured within the applicable grace period,
the Employee may terminate this Agreement and the Employee will leave with the
rights described in Section 5(b) of this Agreement.

         SECTION 6.  MATTERS NOT CONSTITUTING "INDEPENDENCE ASSURANCES".
The following shall specifically not be considered as "Independence Assurances"
but shall nevertheless govern the relationship by and among UST, USTC and AM:

                                      5
<PAGE>   6

         (a)     The location of AM's business for a period of three years from
January 1, 1995 on two floors at 40 Court Street, Boston, MA.  The Employee and
the other Employee/Principals shall cause AM to give twelve months written
notice of termination of such occupancy, if they so elect, no earlier than
December 31, 1996.  "Fair Rental" shall be charged or allocated by UST or USTC
for AM's premises, and UST or USTC shall give AM "high priority" with respect
to remodeling and upgrading of space.

         (b)     Matters covered in a Memorandum dated September 14, 1994 on
"Capital Expenditures/Intercompany Charges" which is attached as Schedule VI
hereto.

         (c)     The taking of reasonable steps by the Employee and the other
Employee/Principals to cause that appropriate levels of profit from AM's
business to be reinvested in the business (infrastructure, systems, facilities,
product development, compensation to staff members who are not Principals,
additional staff) during the Total Term (as hereinafter defined).  For the year
1995, the amount considered "appropriate" would be the investment of
approximately five percent (5%) of "Base Annual Revenues of AM" as defined in
Section 10.

         (d)     The amortization of AM capital expenditures over a period in
accordance with UST's and USTC's then current policy to the extent it is
consistent with GAAP.  In connection with the foregoing capital expenditures,
at the reasonable request of AM funding will be provided by UST and/or USTC
which will charge AM a fair interest rate for the cost of capital employed.
(See also Schedule VI).

         (e)     The providing of such information as is reasonably necessary
for UST to manage its affairs and responsibilities subject to client
confidentiality, including but not limited to information necessary to comply
with generally accepted accounting principles ("GAAP") in the preparation of
financial statements, budgets and profit plans, and for shareholder
communications, and responses to regulatory requests.

         (f)     The actions of all Employee Principals shall remain subject,
without limitation, to the terms of UST's Code of Ethics, the Payment Approval
Policy and the other Policies set forth in Schedule II hereto.

         SECTION 7.       TERMINATION OF EMPLOYMENT BY USTC.
  
         (a)     Employee's employment may be terminated by USTC (by majority
vote of its Board of Directors) in the following circumstances:

                 At any time after due notice and reasonable opportunity to
                 correct such conduct, (i) in the event of Employee's material
                 breach of any of the terms of this Employment Agreement; (ii)
                 in the event of Employee





                                      6
<PAGE>   7
                 causing a material breach of any of the other
                 Employee/Principals' duties to UST and USTC under Section 10
                 (Revenue Sharing Provision ); (iii) in the event of Employee's
                 willful misconduct in the performance of the Employee's duties
                 hereunder including, without limitation, but subject to
                 Sections 5 and 6 hereof, Employee's willful refusal to carry
                 out any "proper direction" by USTC's Board of Directors with
                 respect to the services to be rendered by Employee hereunder
                 or the manner of rendering such services; or (iv) in the event
                 of Employee's conviction of a crime involving moral turpitude.
                 The term "proper direction" as used in clause (iii) above, may
                 not be used in connection with an instruction, direction or
                 order which would cause UST or USTC to violate an
                 "Independence Assurance".

         (b)     In the event of Employee's death during the term of
employment,  unless otherwise determined by the Employee/Principals acting
pursuant to the Unifying Agreement, USTC's and UST's obligations to pay further
compensation hereunder shall cease as of the date of death, except that any
amounts due under Section 11 hereof or otherwise owed to Employee under welfare
or benefit plans or for deferred compensation and any amounts heretofore
accrued under Sections 3.1 and 3.2 of the Unifying Agreement, shall be paid
when due to the Employee's estate or named beneficiary.

         SECTION 8.       OFFICE AND DUTIES.  During the Original Term, any
Renewal Term, and the Phase II Term, if any, (hereinafter the "Total Term"),
Employee shall hold such positions and perform such duties relating to AM's
business and operations as are described on Schedule I hereto, and as may
otherwise from time to time be assigned to Employee by the Employee/Principals
consistent with all of the terms of this Agreement.  During the Total Term and
while employed by USTC, Employee shall devote (except as noted on Schedule I)
substantially all of Employee's business time to the Employee's duties
hereunder and shall, to the best of Employee's ability, perform such duties in
a manner which will faithfully and diligently further the business and
interests of AM.

         At any time while employed by USTC, Employee shall not directly or
indirectly solicit the business of any Past, Present, or Potential Clients (as
hereinafter defined) except on behalf and for the benefit of AM, or pursue any
other business activity, including, without limitation, serving as an officer,
director, employee, or adviser to any business entity other than AM, without
UST's and USTC's prior written consent; provided, however, that Employee may
without such consent, render without compensation investment advisory services
to immediate members of Employee's family, which shall include the Employee and
any trust or account which is comprised entirely of assets held for the benefit
of such Employee and/or immediate members of Employee's family, and may be
involved in such additional activities without such consent as are listed on
the Schedule I hereto.  Employee agrees to travel to whatever





                                      7
<PAGE>   8
extent is reasonably necessary in the conduct of AM's business.  Except when
engaged in such travel, Employee's place of employment shall be in the greater
Boston area of Massachusetts unless otherwise agreed to by Employee, UST and
USTC, and the Employee/Principals acting in accordance with the Unifying
Agreement.

         The term "Past Client" shall mean at any particular time any person or
entity who within three years prior to such time had been but at such time is
not an advisee, investment advisory customer, or client of AM.

         The term "Present Client" shall mean at any particular time any person
or entity who is at such time an advisee, investment advisory customer, or
client of AM.

         The term "Potential Client" shall mean at any particular time any
person or entity to whom AM, through any of the Employee/Principals or other of
its employees, has within three years prior to such time offered (by means of a
personal meeting, telephone call, or a letter or a written proposal
specifically directed to the particular person or entity) to serve as
investment adviser but who is not at such time an advisee or investment
advisory customer or client of AM.  The preceding sentence is meant to exclude
form letters and blanket mailings.

         The terms "Client" or "Client List" when used herein shall mean all
Past, Present, and Potential Clients as heretofore defined.  The term "Client"
when used in this Employment Agreement with respect to wrap accounts, shall
mean the wrap sponsors and the brokers employed by such wrap sponsors but not
the underlying wrap account holders.

         SECTION 9.       BENEFITS.  Employee shall participate, to the extent
Employee is eligible and in a manner and to an extent that is fair and
appropriate in light of the position and duties granted to Employee hereunder,
in all pension, profit-sharing, group insurance, or other fringe benefit plans
(other than UST corporate stock compensation plans) which UST or USTC may
hereafter in their absolute discretion make available generally to employees of
AM, but neither UST nor USTC will be required to establish any such program or
plan.  Employee shall be entitled to such vacations and to reimbursement of
such expenses as UST's or USTC's policies allow to all employees having
comparable responsibilities and duties.  So long as such additional benefits
are payable out of or accrue to "AM's Share of Revenues" as hereinafter
defined, the Employee/Principals may provide additional executive benefits to
themselves in addition to those provided by UST, provided that no such benefit
be qualified under Section 401 of  the Internal Revenue Code or non-qualified
(under Section 401 of the Internal Revenue Code) pursuant to the terms of a
plan or arrangement which operates in a manner that is substantially similar or
mirrors a qualified plan, and provided further that the award of any such
benefits does not increase the cost to UST of providing benefits to UST
employees who are not employees of AM.

         SECTION 10.      REVENUE SHARING PROVISION.  The purpose of this
Revenue Sharing Provision is to provide UST with an acceptable stream of income
and to permit AM to retain a specified percentage of its revenues for use by
Employee/Principals, including the Employee, in their discretion in paying
expenses of operation, including compensation.  It is intended to allow the
Employee and the other Employee/Principals to be compensated for enhancing and
growing AM's revenues in a substantial manner and to make operating decisions
freely within the limits of "AM's Share of Revenues," as such term is defined
below.  See Schedule V for examples of Revenue Sharing calculations.

         (a)     ALLOCATION OF REVENUES.  "Base Annual Revenues of AM" in 1994
and all subsequent years for purposes of this Revenue Sharing Provision shall
be AM's actual 1994 Revenues less $750,000, such total amount to be
appropriately modified to reflect changes in the United States Bureau of Labor
Statistics Cost of Living Index for the Boston Metropolitan Statistical Area or
any designated successor index for 1995 and all subsequent years.  The term
"Revenues" shall mean AM's revenues calculated on an accrual basis in
accordance with GAAP, (excluding shared revenues paid to investment or other
firms or professionals and generated from AM clients), consistent with USTC's
usual practice.

         During the pro-rated six month period commencing July 1, 1994 and
         ending December 31, 1994, and for each calendar year and for portions
         thereof on a pro-rated basis thereafter, AM shall retain sixty percent
         (60%) ("Base AM Retention"), of AM's pro-rated actual Revenues and AM
         shall make available to USTC for distribution to UST forty percent
         (40%) ("Base UST Amount"), subject to adjustment as set forth in this
         Section 10(a).

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar of AM's annual revenues
         over Base Annual Revenues of AM, AM shall retain an additional $.40,
         and an additional $.60 shall be allocated to UST, provided that in no
         event shall UST's Share of Revenues exceed fifty percent (50%) of
         actual Annual Revenues of AM.

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar that actual Annual
         Revenues of AM are less than Base Annual Revenues of AM, Base AM
         Retention shall be reduced by $.40 and the Base UST Amount shall be
         reduced by $.60, provided that in no event shall  UST's Share of
         Revenues be less than thirty percent (30%) of Annual Revenues of AM.

         Amounts retained by AM as aforesaid are herein referred to as "AM's
Share of Revenues".  Amounts allocated to UST as aforesaid are herein referred
to as "UST's Share of Revenues".





                                      9
<PAGE>   10
         (b)     FLOOR INCENTIVE.  In addition, during the Original Term of
this Agreement (thirty months), AM shall retain a "Floor Incentive" of $40,000
per month from "UST's Share of Revenues" ($1.2 million in the aggregate).  The
"Floor Incentive" shall be accrued by USTC and paid pursuant to subsection
(d)(iv) hereof, and shall be excluded from the limitations of Section 5(a)(iv)
of this Agreement.  In the event of a material breach by UST or USTC of this
Agreement during the Original Term (which breach is not cured during the
applicable grace period and is either confirmed by the arbitrator under Section
18 hereof or not contested by UST or USTC), the Employee/Principals (for
distribution in accordance with the Unifying Agreement) may elect to receive an
aggregate lump-sum payment determined by multiplying (x) the monthly "Floor
Incentive" by (y) the remaining months in the Original Term.  If a "Triggering
Event" occurs during the period January 1, 1995 through June 30, 1998, the
aggregate Floor Incentive, net of tax, accrued during the four full calendar
quarters next preceding the date of the Triggering Event, shall not be deducted
from "AM's After Tax Revenues" for purposes of calculating the Section 11
Formula Payment.  Moreover, if a Triggering Event occurred before all Floor
Incentives have been paid, UST or USTC's successor shall assume responsibility
to make the remaining Floor Incentive payments.

         (c)     SPECIAL PROVISIONS.  It is understood and agreed that:

                 (i)      The balance of "Base AM Retention" for the period
                          July 1, 1994 through December 31, 1994 shall be paid
                          by UST or USTC to AM no later than February 15, 1995.

                 (ii)     All amounts due to Robert B. Zevin pursuant to his
                          agreement dated September 30, 1994 with USTC shall be
                          considered as expenses to come out of "AM's Share of
                          Revenues" in each year in accordance with the
                          Unifying Agreement.

                 (iii)    The application of this Section may make it
                          unattractive for AM to enter a business activity with
                          a profit margin of less then 40%.  Accordingly, the
                          parties have agreed to negotiate separate "side
                          letters" with respect to revenue sharing on any new,
                          lower-margin business opportunities identified in the
                          future by AM and regarded as worthy of pursuit by UST
                          and/or USTC.

                 (iv)     The parties hereto further understand and acknowledge
                          that the term "Revenues" as used herein is intended
                          to cover revenues of AM as they now exist and as they
                          may grow or contract internally, and not revenues
                          from the acquisition by UST or USTC of another
                          investment advisory firm concerning which the parties
                          hereto agree to negotiate in good faith as to revenue
                          sharing.

                 (v)      The investment return on allocated, but unexpended,
                          portions of AM's Share of Revenues shall be measured
                          at the end of each calendar quarter by multiplying
                          the average of the month end balances during such
                          quarter by the published thirteen week U.S. Treasury
                          Bill Rate at the end of such calendar quarter.This
                          interest income shall be added to "AM's Share of
                          Revenues".

         (d)     Transfer of Revenues to UST; Retention of Revenues by
                 -----------------------------------------------------
                 USTC;Compensation of Employee/Principals.
                 -----------------------------------------

                 (i)      The Employee/Principals and AM shall use AM's Share
                          of Revenues to pay and provide for AM's business
                          expenses and expenditures including, without
                          limitation, investment in AM's business and new
                          products (see Section 6(d) above) and salaries of its
                          employees, except that any federal, state or local
                          income tax to which USTC is subject shall be the
                          responsibility of UST and shall not be treated as a
                          business expense of AM.

                 (ii)     The Employee/Principals shall incur no expenses or
                          obligations on behalf of AM which exceed USTC's
                          ability to pay or provide for them when due out of
                          AM's Share of Revenues.  The Employee/Principals
                          shall not incur obligations or make binding
                          commitments on behalf of USTC or UST not related to
                          AM's business and requiring expenditures by USTC in
                          excess of $50,000, or make representations to third
                          parties that they have the authority to do so.
                          However, the Employee/Principals may represent and
                          advertise that AM is a division of USTC and an
                          affiliate of UST, and other than as limited above in
                          this Section 10 (d)(ii), may incur obligations or
                          make binding commitments on behalf of USTC in the
                          ordinary course of business.

                 (iii)    The Employee/Principals may (subject to Policies and
                          applicable laws and regulations) pay to AM's
                          employees, including the Employee and the other
                          Employee/Principals, at times and in amounts and
                          proportions determined in accordance with the
                          Unifying Agreement, the balance of AM's Share of
                          Revenues remaining after the payment of all of the
                          amounts required under subsection (d)(i) hereof and
                          subject to Section 5(a)(iv).

                  (iv)    The Employee's Revenue Sharing compensation out of
                          "AM's Share of Revenues" shall be allocated in
                          accordance with the terms of the Unifying Agreement.
                          The Employee/Principals have provided to UST and USTC
                          in the Unifying Agreement their procedures for
                          determining changes, if any, in the allocation of





                                      11
<PAGE>   12
                          Revenues among the Employee/Principals.  If an
                          Employee/Principal chooses to leave USTC's employ
                          after bypassing this change determination mechanism
                          or refusing to abide by its results, the
                          Employee/Principal shall be deemed to have committed
                          a material breach of this Employment Agreement.

                 (v)      The Employee/Principals and AM shall make available
                          to UST, UST's Share of Revenues upon reasonable
                          request by UST and action by USTC's Board of
                          Directors.  The Employee/Principals shall not spend
                          or incur obligations to spend any part of UST's Share
                          of Revenues.

         (e)     ADMINISTRATION.  The parties hereto and the other
Employee/Principals agree to meet and consult to endeavor in good faith to
agree on appropriate procedures, in addition to Policies and applicable laws
and regulations,  for administering the provisions of this Section 10.

         The Employee/Principals shall retain control over all expenditures of
AM, subject to the power of USTC's Board of Directors to exercise its rights
under Section 5A, and subject to this Revenue Sharing Provision, and
recognizing that AM is a division of USTC.

         (f)     TERM AND STATUS AS PARTIES.  This Revenue Sharing Provision
shall continue in effect until terminated by agreement of UST, USTC, and the
Employee/Principals acting in accordance with the Unifying Agreement.  If the
employment of Employee by USTC ceases other than as a result of a material
breach by UST or USTC of this Employment Agreement, such Employee shall
thereupon automatically cease to be a party to this Revenue Sharing Provision
and to have any rights or obligations under this Section, and shall cease to be
an Employee/Principal for the purposes of this Provision.  Nothing  in this
Employment Agreement shall be construed to grant to the Employee any right to
be employed by USTC beyond the terms of this Employment Agreement.

         SECTION 11.      FORMULA PAYMENT.  If Employee is still employed by
USTC at the time of a "Triggering Event" (as hereinafter defined), the Employee
shall receive Employee's share of a formula payment (the "Formula Payment") as
follows:

         (a)     Unless otherwise agreed by the Employee/Principals acting in
accordance with the Unifying Agreement, the Employee's share of the Formula
Payment shall be the percentage set forth after the Employee's name on Schedule
III hereto;

         (b)     The "Formula Payment" shall be 3.33 times "AM's After Tax
Revenues" (as hereinafter defined and meaning generally UST's Share of Revenues
minus taxes);





                                      12
<PAGE>   13
         (c)     "AM's After Tax Revenues" shall be the portion of AM's
after-tax Revenues contributed, accruing or allocated to UST for the four full
calendar quarters next preceding the date of the Triggering Event; determined
in accordance with GAAP consistently applied in such periods.  For purposes of
this Subsection, there shall be assumed a combined federal and state tax rate
of 38%, such rate to be appropriately adjusted to reflect changes in applicable
federal and state corporate tax rates.  An example of this calculation is set
forth on Schedule V.

         (d)     The Formula Payment shall be adjusted in accordance with
Schedule IV hereto for gain or loss of AM clients between the signing of a
definitive merger, consolidation or acquisition agreement or an agreement
related to another Triggering Event and the Closing Date related to any such
Triggering Event.

         (e)
                 (i)      At the Closing Date of a Triggering Event, three Key
                          Employees shall be identified as follows.  For every
                          person who has been an Employee/Principal at any time
                          during the previous 15 months there shall be
                          calculated a Weighted Average Share equal to the sum
                          of (a) the share of the Formula Payment such person
                          was entitled to receive from time-to-time during the
                          preceding 15 months in accordance with Schedule III
                          and subsequent changes thereto by the
                          Employee/Principals acting in accordance with the
                          Unifying Agreement times (b) the number of days such
                          person was entitled to each such share.  The three
                          persons among those who are or have been
                          Employee/Principals on the Closing Date of the
                          Triggering Event or during the previous 15 months who
                          have the three highest Weighted Average Shares shall
                          be deemed the "Key Employees".

                 (ii)     If only one of the three Key Employees is no longer
                          in the employ of USTC as of the Closing Date of such
                          Triggering Event, then all of that Key Employee's
                          Weighted Average Share of the Formula Payment
                          (expressed by X%) shall be placed in escrow in the
                          manner contemplated by Section 11(f). To determine
                          the distribution of each of the three escrowed
                          installments use the following formula.  Revenues of
                          AM (as defined in Section 10(a)) for the last full
                          calendar year prior to a Triggering Event should then
                          be determined (the "Measuring Year").  Such Revenues
                          of AM for the Measuring Year multiplied by a decimal
                          representing 100% - X% equals the "Minimum Revenues".
                          If during the next full calendar year following the
                          Measuring Year, Revenues of AM are equal to or less
                          than Minimum Revenues none of the one-third of the
                          escrowed amount for such year will be paid to the
                          remaining Employee/Principals in accordance with this
                          Section and all of it will be retained by UST's or
                          USTC's successor.  If Revenues of AM for





                                      13
<PAGE>   14
                          that calendar year exceed Minimum Revenues, (i) take
                          the U.S. Dollar amount of such excess above the
                          Minimum Revenues and divide it by the Revenues of AM
                          for the Measuring Year minus the Minimum Revenues,
                          (ii) then multiply the resulting fraction by
                          one-third of the full escrowed amount, (iii) the
                          product of the foregoing formula should be delivered
                          to the remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and the remainder of that installment
                          should be retained by UST or UST's successor.
                          Similar calculations should be made for the second
                          and third installments, but in each case using the
                          same Minimum Revenues.

                 (iii)    If two or more of the Key Employees are no longer in
                          the employ of USTC as of the Closing Date of such
                          Triggering Event, then 100% of the Formula Payment
                          shall be placed in escrow in the manner contemplated
                          by Section 11(f).  To determine the distribution of
                          each of the three escrowed installments use the
                          following formula.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment equal or exceed
                          Revenues of AM for the Measuring Year, all of that
                          escrowed installment should be distributed to the
                          remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and none should be retained by UST or
                          USTC's successor.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment are less than
                          Revenues of AM for the Measuring Year, divide the
                          U.S. Dollar amount of Revenues of AM for such last
                          full calendar year by the U.S. Dollar amount of
                          Revenues of AM for the Measuring Year and multiply
                          the resulting fraction by one-third of the full
                          escrowed amount.  The product of the foregoing
                          calculation should be delivered to the remaining
                          Employee/Principals as a group for distribution in
                          accordance with the Unifying Agreement and the
                          remainder should be retained by UST's or USTC's
                          successor.

         (f)     Seventy percent (70%) of the Employee's share of the Formula
Payment shall be paid in cash within twenty (20) days of the Closing Date of
the Triggering Event.  The remaining thirty percent (30%) shall be placed in
escrow with an escrow agent acceptable to both UST and Employee/Principals and
paid to the Employee or the Employee's estate as provided in Section 7(b) in
installments of one third of the escrowed amount at the end of years one, two
and three (which may not be calendar years) after the Closing Date of the
Triggering Event plus interest, at the interest rates on the date of the
Closing Date of the Triggering Event of one, two and three year Treasury
securities,  provided that at the time of each such installment payment, the
Employee has not been terminated with cause or for a material breach or has not
voluntarily ceased to be employed by AM.

         (g)     A "Triggering Event" shall be deemed to have occurred when:

                 (i)      there occurs the signing of a definitive agreement of
                          merger or consolidation of UST or USTC with any other
                          corporation, other than a merger or consolidation
                          which would result in the voting securities of UST or
                          USTC 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 USTC, or such surviving entity outstanding
                          immediately after such merger or consolidation;
                          provided, however, that a merger or consolidation
                          effected to implement a recapitalization,
                          reorganization or restructuring of UST or USTC (or
                          similar transaction) in which no "person" (as defined
                          in (g)(iii) below) acquires more than fifty percent
                          (50%) of the combined voting power of UST's then
                          outstanding securities shall not constitute a
                          Triggering Event; or

                 (ii)     there occurs a closing of a sale or other disposition
                          by UST of more than 50% of UST's, USTC's or AM's
                          business and assets; or

                 (iii)    any "person", as such term used in Section 13(d) and
                          14(d) of the Exchange Act other than UST or USTC or
                          any of their respective subsidiaries or affiliates or
                          any trustee or other fiduciary holding securities
                          under an employee benefit plan of either of them or
                          any of their subsidiaries or 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
                          50% percent or more of the combined voting power of
                          UST's or USTC's then outstanding securities.

         If (i) more than 50% of UST's then outstanding common stock or assets
are acquired by a "person" whose consolidated assets prior to the Triggering
Event were less than $4 billion or (ii) UST's business assets and operations
are consolidated with those of another bank or bank holding company and the
resulting entity has consolidated assets of $5.5 billion or less, a Triggering
Event shall be deemed to have occurred, but the length of the Phase II term of
employment of the Employee shall be increased automatically by one additional
year.

         (h)     If UST agrees to be acquired by an entity with a public image
so starkly negative that AM's affiliation with that entity would be reasonably
likely, by itself, to cause a loss of more than 25% of AM's gross revenues in
one year (unless the parties





                                      15
<PAGE>   16
mutually agree to the contrary), the Employee/Principals at their option acting
pursuant to the terms of the Unifying Agreement (and provided such right is
exercised within 30 days of the public announcement of such acquisition) will
be relieved of all of the Employee's obligations under the Phase II Term and no
Formula Payment will be made.

         (i)     The parties acknowledge that any such Formula Payment is
intended to compensate the Employee for: (i) the automatic extension of this
Agreement occurring by reason of a Triggering Event; (ii) the Phase II
Non-Competition covenants specified in Section 12; and (iii) the loss of
opportunity to make up for reduced rate of compensation which such Employee
earned with USTC for periods prior to the effective date of this Agreement.

         SECTION 12.      PHASE II NON-COMPETITION COVENANTS.

         (a)     During the longer of the Phase II Term (as defined in Section
4) if Phase II shall commence while Employee is employed by USTC hereunder or
while Employee is employed by USTC during or after such Phase II Term
hereunder, Employee shall not, except in the course of his employment with
USTC, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, stockholder,
                          consultant, adviser, subsidiary, affiliate,
                          independent contractor or otherwise, investment
                          advisory services to any person or entity;

                 (ii)     Interfere with AM's relations with any person or
                          entity who at any time during such period was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person, other than by
                          discharge of such person as a part of Employee's
                          duties.

         (b)     Until one year following the end of the Phase II Term, if the
Phase II Term should commence while Employee is employed by USTC hereunder or
one year following the termination of Employee's employment with USTC during or
after such Phase II Term, Employee shall not, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, independent
                          contractor or otherwise, investment advisory services
                          to any person or entity who as of the date of the
                          termination or expiration of Employee's employment





                                      16
<PAGE>   17
                          with USTC was or had been a Client (which means Past,
                          Present, and Potential Client);

                 (ii)     Interfere with AM's relations with any person or
                          entity who as of the date of the termination or
                          expiration of Employee's employment with USTC was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person.

         (c)     Notwithstanding the provisions of subsections (a)(i) and
(b)(i), the Employee may render without compensation investment advisory
services to any immediate member of Employee's family, which shall include the
Employee and any trust or account which is comprised entirely of assets held
for the benefit of such Employee and/or immediate members of such Employee's
family, and may engage in such other activities as are listed on Schedule I
hereto.

         (d)     Employee and USTC agree that the periods of time and the
unlimited geographic area applicable to the covenants of this Section 12 are
reasonable, in view of the receipt and expected receipt of the Employee's share
of Revenue Sharing as provided in Section 10(c), and other compensation, and
the Formula Payment provided herein; the geographic scope and nature of the
business in which AM is engaged; Employee's knowledge of AM's business; and
Employee's relationships with AM's investment advisory clients.  However, if
such period or such area should be adjudged unreasonable in any judicial
proceeding, then the period of time shall be reduced by such number of months
or such area shall be reduced by elimination of such portion of such area, or
both, as are deemed unreasonable, so that this covenant may be enforced in such
area and during such period of time as are adjudged to be reasonable.

         SECTION 13.      ALL BUSINESS TO BE THE PROPERTY OF USTC; ASSIGNMENT
OF INTELLECTUAL PROPERTY.  During the Phase II Term if Phase II shall commence
while Employee is Employed by USTC hereunder and thereafter while Employee is
employed by AM and/or USTC:

         (a)     Employee agrees that any and all presently existing investment
advisory business of AM and all business developed by Employee or any other
employee of AM, including without limitation all investment advisory contracts,
fees, commissions, compensation records, Client Lists (as defined in Section
8), agreements, and any other incident of any business developed or sought by
AM or earned or carried on by Employee for AM, are and shall be the exclusive
property of USTC for its sole use, and (where applicable) shall be payable
directly to USTC.





                                      17
<PAGE>   18
         (b)     Employee hereby grants to USTC (without any separate
remuneration or compensation other than that received by Employee from time to
time in the course of his or her employment) Employee's entire right, title,
and interest throughout the world in and to, all research, information, Client
Lists, and all other investment advisory, technical and research data made,
conceived, developed and/or acquired by Employee solely or jointly with others
during the period of Employee's employment by USTC, which relate to investment
advice as it was or is now rendered or as it may, from time to time, hereafter
be rendered or proposed to be rendered, but excluding such individual's ideas
and thought processes which are not embodied in written or machine readable
form (all such non-excluded items being referred to as "Intellectual
Property").

         SECTION 14.      CONFIDENTIALITY.  Except in performance of services
for USTC, Employee shall not, either during the Phase II Term if Phase II shall
commence while the Employee is employed by USTC hereunder or thereafter while
employed by AM and/or USTC, use for Employee's own benefit or disclose to or
use for the benefit of any person outside USTC, any information not lawfully
available to the public concerning any Intellectual Property, including Client
Lists, whether Employee has such information in his or her memory or embodied
in writing or other tangible form.  All such Intellectual Property and such
information concerning Intellectual Property, and all originals and copies of
any Intellectual Property, and any other written material relating to the
business of AM, shall be the sole property of USTC.  During such Term or
thereafter, upon the termination of Employee's employment in any manner or for
any reason, Employee shall promptly surrender to USTC all originals and copies
of any Intellectual Property, and Employee shall not thereafter use any
Intellectual Property.

         The foregoing notwithstanding, Employee will have no obligation to AM
or USTC with respect to the disclosure or use of any Intellectual Property or
information concerning Intellectual Property if:

         (a)  Such Intellectual Property or information is or becomes publicly
known or otherwise enters the public domain through no wrongful act of
Employee; or

         (b)  Such Intellectual Property or information is received from a
third party which has no obligation to UST or USTC to maintain it in
confidence.

         Notwithstanding the references to Client Lists above, it shall not be
a violation of this Section or Section 13 hereof for Employee to communicate or
do business with any Past, Present or Potential Client in the course of
Employee's employment with AM and USTC, and any such conduct shall be limited,
if at all, solely by Section 12 hereof.

         SECTION 16.      ASSIGNABILITY.  This Employment Agreement shall be
binding upon and inure to the benefit of UST, USTC, and to any person or firm
who may succeed to the business of UST, USTC, or AM.  This Employment Agreement
shall not be assignable by Employee, but it shall inure to the benefit of
Employee's heirs, executors, administrators and legal representatives.

         SECTION 17.      ENTIRE AGREEMENT.  This Employment Agreement and the
Unifying Agreement contain the entire agreement between USTC and Employee with
respect to the subject matter hereof, and supersede all prior oral and written
agreements between any of UST, USTC, AM and the Employee with respect to the
subject matter hereof, including without limitation any oral agreements
relating to compensation.

         SECTION 18.      ARBITRATION.  In the event the parties hereto
disagree as to whether a material breach has occurred of: (i) the "Independence
Assurances" under Section 5; (ii) USTC's right of termination of Employee's
employment under Section 7; (iii) this Agreement by USTC as described in
Section 19 (b); (iv) the revenue sharing provisions of Section 10; or (v) the
formula payment provisions of Section 11, such dispute shall be settled by
arbitration before a single arbitrator to be then named by UST and a majority
of the Employee/Principals acting in accordance with the Unifying Agreement, in
Boston, Massachusetts in accordance with the Commercial Arbitration Rules of
the American Arbitration Association.  If such arbitrator cannot serve, then a
successor shall be appointed in accordance with such Rules.  If the arbitrator
finds that there has been a material breach (and such breach has not been cured
by UST or USTC within sixty (60) days of such finding or by Employee in
accordance with Section 7 hereof), then the remedies provided for in Section 19
shall become available, as appropriate.

         SECTION 19.      EQUITABLE RELIEF AND OTHER REMEDIES.

         (a)  Employee recognizes and agrees that UST's, USTC's or the
Employee/Principals' remedies at law for any breach of the provisions of
Sections 12, 13 and 14 hereof would be inadequate and that for breach of such
provisions UST, USTC and the Employee/Principals  shall, in addition to such
other remedies as may be available to any of them at law or in equity or as
provided in this Employment Agreement, be entitled to injunctive relief and to
enforce their respective rights by an action for specific performance to the
extent permitted by law, and to the right of set-off against any amounts due to
the Employee by UST, USTC or AM.  Should Employee engage in any activities
prohibited by this Employment Agreement, he or she agrees to pay over to USTC
or UST all compensation received in connection with such activities.  Such
payment shall not impair any other rights or remedies of UST, USTC or AM or
affect the obligations or liabilities of Employee under this Employment
Agreement or applicable law.

         (b)  Any termination by USTC of Employee's employment which is not
authorized by Section 7 hereof shall constitute a material breach of this
Agreement.  In the event of a material breach of this Agreement by UST or USTC
which is not cured pursuant to Section 18, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, USTC
shall pay Employee the Employee's then current Annual Base Salary for a period
equal to the greater of (i) twelve months or (b) the balance of the then
current term of this Agreement.  Any such payments shall not constitute part of
AM's Share of Revenues.  Should such a material breach occur and not be so
cured, the Employee shall be  free to compete, Sections 12, 13 and 14 shall not
apply and the Employee shall leave with the rights described in Section 5(b) of
this Agreement.

         (c)  Without limiting the generality of the foregoing, the parties 
expressly agree





                                       20
<PAGE>   21
that termination without cause of Employee's employment hereunder during the
Phase II Term by UST, USTC or any other person or entity will constitute a
material breach of this Agreement and, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, shall
give Employee the right to salary continuation as set forth in Section 19(b)
hereof.

         SECTION 20.      WAIVERS AND FURTHER AGREEMENTS.  Neither this
Employment Agreement nor any term or condition hereof, including without
limitation the terms and conditions of this Section 20, may be waived in whole
or in part as against UST, USTC, AM or Employee except by written instrument
executed by each of them, expressly stating that it is intended to operate as a
waiver of this Employment Agreement or the applicable term or condition hereof.
Each of the parties hereto agrees to execute all such further instruments and
documents and to take all such further action as the other party may reasonably
require in order to effectuate the terms and purposes of this Employment
Agreement as stated herein.  Furthermore, no waiver may violate the terms of

amended, nor shall any parties be added hereto, nor any change, modification,
consent, or discharge be effected except by written instrument executed by all
three of the Employee, USTC and UST.  Furthermore, no amendment or modification
may violate the terms of the Unifying Agreement and any amendment or
modification shall require action of the Employee/Principals in accordance with
the Unifying Agreement authorizing such amendment or modification.

         SECTION 22.      SEVERABILITY.  If any provision of this Employment
Agreement shall be held or deemed to be invalid, inoperative or unenforceable
in any jurisdiction or jurisdictions, because of conflicts with any
constitution, statute, rule or public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision in question
unenforceable in any other jurisdiction or in any other case or circumstance or
of rendering any other provisions herein contained unenforceable to the extent
that such other provisions are not themselves actually in conflict with such
constitution, statute or rule of public policy, but this Employment Agreement
shall be reformed and construed in any such jurisdiction or case as if such
invalid, inoperative, or unenforceable provision had never been contained
herein and such provision reformed so that it would be enforceable to the
maximum extent permitted in such jurisdiction or in such case.

         SECTION 23.      NO CONFLICTING OBLIGATIONS.  Employee represents and
warrants to USTC and UST that Employee has no other interest or obligation
which is inconsistent or in conflict with this Employment Agreement or which

Consent of the Employee/Principals shall be described herein, action by the
Employee/Principals or their duly authorized representative shall be required
in accordance with the Unifying Agreement, and such action shall be sufficient

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

         AGREEMENT made as of February 14, 1995 and effective January 1, 1995
between United States Trust Company ("USTC"), a banking and trust company
having its principal place of business in Boston, Massachusetts, and joined in
as to certain matters by UST Corp. ("UST"), a Massachusetts corporation also
having its principal place of business in Boston, Massachusetts and the parent
of USTC; and Robert B. Zevin (the "Employee").

                                   BACKGROUND
                                   ----------

         The Employee and the other principals of the Asset Management Division
of USTC ("AM") listed on Schedule I hereto and such other principals as may be
added pursuant to the Unifying Agreement (as hereinafter defined) (all such
employees, while they remain principals, being referred to herein from time to
time as "Employee/Principals") are concerned that previous UST and USTC
practices have not allowed for enough spending to generate growth in AM's
business, or for fully competitive compensation for its principals; want
assurances of continued freedom to manage the AM business; want to participate
in an incentive compensation program which reflects the value created in this
business; and want to make it attractive to any potential acquirer of UST, USTC
or AM to (i) protect existing relationships with AM employees and clients, (ii)
avoid re-writing existing client contracts, and (iii) further AM as a separate
business conducted under the name "United States Trust Company".

         UST and USTC want to stabilize and increase the profitability of AM;
pay competitive compensation; provide incentive compensation reflecting the
growth in the business of AM; and (in the event of a "Triggering Event" as
hereinafter defined) offer an opportunity to a prospective purchaser to retain
the services of Employee and the other Employee/Principals and thereby receive
a continuing stream of profits from AM.

         UST and USTC recognize the importance of Employee to their business
and to USTC's ability to retain AM client relationships, and desire that USTC
employ Employee as an officer and principal of AM for the period of employment
and upon and subject to the terms herein provided.

         UST and USTC wish to be assured that Employee will not compete with
AM's business during the period of employment, and in certain circumstances and
as set forth below will not for a period thereafter solicit any Past, Present,
or Potential Clients (as hereinafter defined) of AM and will not by such
solicitation damage USTC's and AM's goodwill among its clients and the general
public.

                                      1
<PAGE>   2
         Employee desires to be employed by USTC and serve as an
Employee/Principal of AM and to participate in the incentive compensation
program contemplated by this agreement, and to refrain from competing with USTC
or AM or soliciting AM's clients for the periods and upon and subject to the
terms herein provided.

         Employee has been employed by USTC and AM for approximately 21 years;
has while so employed contributed to the acquisition and retention of AM's
clients, and will continue to seek to acquire and retain clients and to
generate goodwill for AM in the future as an officer and employee of USTC and
an Employee/Principal of AM for the periods and on the terms contemplated
hereby.

         When the terms "AM," "AM's business," or the "AM Division" are used
herein, such terms specifically exclude the non- investment advisory business
of USTC such as (1) the business of UST Capital Corp. (venture capital) and (2)
the management of USTC's internal securities portfolio.  Such terms, however,
include the investment return on allocated, but unexpended, portions of AM's
Share of Revenues as reflected on Schedule V. The investment return on
allocated, but unexpended, portions of AM's share of revenues shall be measured
at the end of each calendar quarter by multiplying the average of the month end
balances during such quarter by the published thirteen week U.S. Treasury Bill
Rate at the end of such calendar quarter and such interest income shall be
added to "AM's Share of Revenues".  All current Employee/Principals are listed
on Schedule I.

         Employee, the other Employee/Principals, UST and USTC have entered
into an agreement of even date herewith (the "Unifying Agreement") which
describes generally their agreements and certain procedures they have agreed to
follow among themselves.  This Employment Agreement is executed pursuant to and
in accordance with the terms of the Unifying Agreement.  Certain capitalized
terms used but not defined herein shall have the meanings given them in the
Unifying Agreement.

                                   AGREEMENTS
                                   ----------

         In consideration of the premises, the mutual covenants and the
agreements hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
covenant and agree as follows:

         SECTION 1.       ORIGINAL TERM OF EMPLOYMENT; COMPENSATION.  USTC
agrees to employ Employee for a period of two and one-half (2 1/2) years
beginning on the date hereof (the "Original Term") as an officer of USTC and an
Employee/Principal of AM; and Employee hereby accepts such employment.  USTC
will pay Employee for Employee's services during the Original Term, and any
Renewal Term (as hereinafter provided) and any Phase II Term, the Annual Base
Salary set forth on Schedule I hereto, and such additional annual incentive
payments as shall be determined by the





                                       2
<PAGE>   3
Employee/Principals consistent with the Revenue Sharing Provision (Section 10
hereof),  and subject to such payroll and withholding deductions as are
required by law.  Consistent with the Revenue Sharing Provision, the Employee's
total compensation will be reviewed at least annually in accordance with the
Unifying Agreement, having in mind that such compensation be fair and
reasonable in light of Employee's position and the duties to be performed by
the Employee and the Employee's efforts to enhance the business of AM.

         SECTION 2.       RENEWAL TERMS.  If no "Triggering Event" has occurred
and this Agreement has not been terminated by either party (all as hereinafter
provided) prior to the end of the Original Term, then the Original Term shall
be automatically extended for successive six month renewal terms (each referred
to herein as a "Renewal Term", or collectively as "Renewal Terms") until such
Triggering Event or termination has occurred, or until the Employee shall have
provided at least six months advance written notice to UST and USTC of election
not to enter a Renewal Term.

         SECTION 3.       NOTICE OF TERMINATION OF ORIGINAL TERM BY EMPLOYEE.
On or before the last day of the second year of the Original Term and assuming
that this Agreement has not been earlier terminated or entered upon the Phase
II Term (all as hereinafter provided), the Employee may give written notice to
UST and USTC of termination, whereupon all the provisions of this Agreement
will terminate (except as noted below in this Section 3) on the last day of the
Original Term.  If there has been a material breach of this Agreement by
Employee at any time during the Original Term or any Renewal Term, and the
arbitration under Section 18 hereof has confirmed that a material breach has
been committed by the Employee and such breach is uncured during the applicable
grace period, then the Employee will be subject in full to all of the
restrictions of Section 12, 13 and 14 hereof for the remainder of the
applicable term plus 90 days.  However, should the Employee terminate this
Agreement without a material breach at the end of the Original Term or at the
end of any Renewal Term, Sections 12, 13 and 14 of this Agreement shall not
apply.  Notwithstanding the foregoing, should the Employee terminate this
Agreement as described in either of the immediately preceding two sentences,
UST and USTC will retain all of their respective common law rights against the
Employee with respect to confidentiality, protection of customer lists, trade
secrets, non-competition and similar matters.

         SECTION 4.       PHASE II TERM.  If a Triggering Event occurs during
the Original or a Renewal Term, any such term shall automatically terminate and
the Phase II Term shall commence as of the earlier of the date of signing of a
definitive merger or acquisition agreement or the date of occurrence of such
Triggering Event.  The Phase II Term shall be for a period of three years from
the Closing Date under such definitive merger, consolidation or acquisition
agreement, or the date of the agreement related to any other such Triggering
Event, but in no event for longer than four years from such signing date, and
shall be terminable in the same manner as the Original





                                       3
<PAGE>   4
Term under Section 3 above (the "Phase II Term"). The "Closing Date" shall mean
the date on which the merger or consolidation becomes effective, the
acquisition is consummated or the change in corporate ownership related to any
other such Triggering Event takes effect. If the revenues of the AM business
decline precipitously and the Formula Payment described in Section 11 below
would be less than $3 Million, then the Employee may decline to accept the
Formula Payment and the Phase II Term.  If the AM revenues likewise decline,
and the Formula Payment described in  Section 11 below would be less than $5
Million, the Employee/Principal may elect to reduce the Phase II Term by one
year.

         SECTION 5.       TERMINATION BY EMPLOYEE FOR BREACH OF "INDEPENDENCE
ASSURANCES."  In the event of the material breach by UST or USTC (or their
respective successors) of any one or more of the "Independence Assurances"
listed below, the Employee/Principals, acting in accordance with the Unifying
Agreement, shall have the right (subject to compliance with Section 18 hereof)
but not the obligation, upon 30 days prior written notice to UST and USTC, to
terminate this Agreement.

         (a)     "Independence Assurances" shall consist of UST's and USTC's
non-interference (unless requested by the Employee/Principals of AM acting in
accordance with the Unifying Agreement) in the following:

                 (i)  The Employee/Principals control of AM's investment
philosophy and investment approach, business strategy, conduct of investment
analysis, portfolio selection, marketing, client retention and acceptance of
new clients, and client service;

                 (ii)  Authority of the Employee/Principals to hire and fire AM
personnel within the scope of UST's "Policies" (as hereinafter defined) and
applicable Federal and Massachusetts laws, subject to UST's right to approve
any person chosen by the Employee/Principals as the Senior Principal of AM,
which person shall also serve initially (i) as the Chief Executive Officer of
USTC, and (ii) on USTC Board of Directors.  UST, as sole shareholder of USTC,
subject to the terms of the Unifying Agreement and this Agreement, will at all
times retain the right to select a Chief Executive Officer of USTC who is not
an employee of AM.  USTC will not, however, select the Senior Principal;

                 (iii)  The Employee/Principals' authority to set AM client
fees based on their judgment concerning the market for services rendered by AM;

                 (iv)  The Employee/Principals' authority to establish AM's
operating expense budget and compensation practices, limited by "AM's Share of
Revenues" as provided in Section 10 (See Schedule V for example); and limited
further with respect to total cumulative cash incentive compensation for
Employee/Principals in the aggregate accrued in each of the years ending
December 31, 1994 and December 31, 1995, to $1.3 million plus incentive
compensation accrued in 1993 (it being understood





                                       4
<PAGE>   5
that the Formula Payment is not to be regarded as cash incentive compensation
for any purposes);

                 (v)  The Employee/Principals' authority to add and delete
Employee/Principals of AM in accordance with the Unifying Agreement; and

                 (vi)  The recognition by UST and USTC that AM, in pursuit
of its "socially-sensitive" investment objectives, may take some public
positions which may not represent the views of UST or USTC management.  The
Employee, however, recognizes that Employee's actions will remain subject to
the provisions of the Code of Ethics, Employment Policies, and certain other
key corporate policies of UST and USTC listed on and attached to Schedule II
hereto ("Policies"), as revised from time to time on a company-wide basis in
the ordinary course of UST's and USTC's business (which revisions shall be made
available to Employee at UST's principal office in Boston); and applicable
Federal and Massachusetts laws, regulations, policies, orders or understandings
in use by or applicable to UST and USTC.

         (b)     In the event that any of the "Independence Assurances" have
been  materially breached and not cured pursuant to Section 18, the Employee
may act either individually or in concert with any other Employee/Principal or
Employee/Principals or other employees so as to constitute a "person" as
defined in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934 (the
"Exchange Act"), in electing to terminate their Employment Agreements, e.g.
they may collectively decide to give five (5) days notice and leave USTC to
form a new business which may directly compete with AM's business and Sections
12, 13 and 14 of this Agreement will not apply.

         SECTION 5A.  OVERSIGHT FUNCTION OF USTC'S BOARD OF DIRECTORS.
USTC's Board of Directors (a majority of whom shall not be Employee/Principals)
shall continue to exercise its oversight function of the business activities of
AM.  In performing such oversight function, USTC's Board the Directors will
assure itself that AM's business and operations are being conducted in a manner
consistent with applicable law and regulations, and such Board will be expected
to meet its fiduciary responsibilities to USTC and its depositors, and to UST,
in all respects, including without limitation, the prevention of corporate
waste of assets and taking steps to see that AM's business is operated with
their respective best interests in mind.  If in performing such oversight
function, the Board causes UST or USTC to breach an Independence Assurance and
such breach is (a) confirmed by the arbitrator under Section 18 or not
contested by UST or USTC and (b) not cured within the applicable grace period,
the Employee may terminate this Agreement and the Employee will leave with the
rights described in Section 5(b) of this Agreement.

         SECTION 6.  MATTERS NOT CONSTITUTING "INDEPENDENCE ASSURANCES".
The following shall specifically not be considered as "Independence Assurances"
but shall nevertheless govern the relationship by and among UST, USTC and AM:

                                      5
<PAGE>   6
         (a)     The location of AM's business for a period of three years from
January 1, 1995 on two floors at 40 Court Street, Boston, MA.  The Employee and
the other Employee/Principals shall cause AM to give twelve months written
notice of termination of such occupancy, if they so elect, no earlier than
December 31, 1996.  "Fair Rental" shall be charged or allocated by UST or USTC
for AM's premises, and UST or USTC shall give AM "high priority" with respect
to remodeling and upgrading of space.

         (b)     Matters covered in a Memorandum dated September 14, 1994 on
"Capital Expenditures/Intercompany Charges" which is attached as Schedule VI
hereto.

         (c)     The taking of reasonable steps by the Employee and the other
Employee/Principals to cause that appropriate levels of profit from AM's
business to be reinvested in the business (infrastructure, systems, facilities,
product development, compensation to staff members who are not Principals,
additional staff) during the Total Term (as hereinafter defined).  For the year
1995, the amount considered "appropriate" would be the investment of
approximately five percent (5%) of "Base Annual Revenues of AM" as defined in
Section 10.

         (d)     The amortization of AM capital expenditures over a period in
accordance with UST's and USTC's then current policy to the extent it is
consistent with GAAP.  In connection with the foregoing capital expenditures,
at the reasonable request of AM funding will be provided by UST and/or USTC
which will charge AM a fair interest rate for the cost of capital employed.
(See also Schedule VI).

         (e)     The providing of such information as is reasonably necessary
for UST to manage its affairs and responsibilities subject to client
confidentiality, including but not limited to information necessary to comply
with generally accepted accounting principles ("GAAP") in the preparation of
financial statements, budgets and profit plans, and for shareholder
communications, and responses to regulatory requests.

         (f)     The actions of all Employee Principals shall remain subject,
without limitation, to the terms of UST's Code of Ethics, the Payment Approval
Policy and the other Policies set forth in Schedule II hereto.

         SECTION 7.  TERMINATION OF EMPLOYMENT BY USTC.

         (a)     Employee's employment may be terminated by USTC (by majority
vote of its Board of Directors) in the following circumstances:

                 At any time after due notice and reasonable opportunity to
                 correct such conduct, (i) in the event of Employee's material
                 breach of any of the terms of this Employment Agreement; (ii)
                 in the event of Employee 

                                      6
<PAGE>   7
                 causing a material breach of any of the other
                 Employee/Principals' duties to UST and USTC under Section 10
                 (Revenue Sharing Provision ); (iii) in the event of Employee's
                 willful misconduct in the performance of the Employee's duties
                 hereunder including, without limitation, but subject to
                 Sections 5 and 6 hereof, Employee's willful refusal to carry
                 out any "proper direction" by USTC's Board of Directors with
                 respect to the services to be rendered by Employee hereunder
                 or the manner of rendering such services; or (iv) in the event
                 of Employee's conviction of a crime involving moral turpitude.
                 The term "proper direction" as used in clause (iii) above, may
                 not be used in connection with an instruction, direction or
                 order which would cause UST or USTC to violate an
                 "Independence Assurance".

         (b)     In the event of Employee's death during the term of
employment,  unless otherwise determined by the Employee/Principals acting
pursuant to the Unifying Agreement, USTC's and UST's obligations to pay further
compensation hereunder shall cease as of the date of death, except that any
amounts due under Section 11 hereof or otherwise owed to Employee under welfare
or benefit plans or for deferred compensation and any amounts heretofore
accrued under Sections 3.1 and 3.2 of the Unifying Agreement, shall be paid
when due to the Employee's estate or named beneficiary.

         SECTION 8.  OFFICE AND DUTIES.  During the Original Term, any
Renewal Term, and the Phase II Term, if any, (hereinafter the "Total Term"),
Employee shall hold such positions and perform such duties relating to AM's
business and operations as are described on Schedule I hereto, and as may
otherwise from time to time be assigned to Employee by the Employee/Principals
consistent with all of the terms of this Agreement.  During the Total Term and
while employed by USTC, Employee shall devote (except as noted on Schedule I)
substantially all of Employee's business time to the Employee's duties
hereunder and shall, to the best of Employee's ability, perform such duties in
a manner which will faithfully and diligently further the business and
interests of AM.

         At any time while employed by USTC, Employee shall not directly or
indirectly solicit the business of any Past, Present, or Potential Clients (as
hereinafter defined) except on behalf and for the benefit of AM, or pursue any
other business activity, including, without limitation, serving as an officer,
director, employee, or adviser to any business entity other than AM, without
UST's and USTC's prior written consent; provided, however, that Employee may
without such consent, render without compensation investment advisory services
to immediate members of Employee's family, which shall include the Employee and
any trust or account which is comprised entirely of assets held for the benefit
of such Employee and/or immediate members of Employee's family, and may be
involved in such additional activities without such consent as are listed on
the Schedule I hereto.  Employee agrees to travel to whatever 

                                      7
<PAGE>   8
extent is reasonably necessary in the conduct of AM's business.  Except when
engaged in such travel, Employee's place of employment shall be in the greater
Boston area of Massachusetts unless otherwise agreed to by Employee, UST and
USTC, and the Employee/Principals acting in accordance with the Unifying
Agreement.

         The term "Past Client" shall mean at any particular time any person or
entity who within three years prior to such time had been but at such time is
not an advisee, investment advisory customer, or client of AM.

         The term "Present Client" shall mean at any particular time any person
or entity who is at such time an advisee, investment advisory customer, or
client of AM.

         The term "Potential Client" shall mean at any particular time any
person or entity to whom AM, through any of the Employee/Principals or other of
its employees, has within three years prior to such time offered (by means of a
personal meeting, telephone call, or a letter or a written proposal
specifically directed to the particular person or entity) to serve as
investment adviser but who is not at such time an advisee or investment
advisory customer or client of AM.  The preceding sentence is meant to exclude
form letters and blanket mailings.

         The terms "Client" or "Client List" when used herein shall mean all
Past, Present, and Potential Clients as heretofore defined.  The term "Client"
when used in this Employment Agreement with respect to wrap accounts, shall
mean the wrap sponsors and the brokers employed by such wrap sponsors but not
the underlying wrap account holders.

         SECTION 9.  BENEFITS.  Employee shall participate, to the extent
Employee is eligible and in a manner and to an extent that is fair and
appropriate in light of the position and duties granted to Employee hereunder,
in all pension, profit-sharing, group insurance, or other fringe benefit plans
(other than UST corporate stock compensation plans) which UST or USTC may
hereafter in their absolute discretion make available generally to employees of
AM, but neither UST nor USTC will be required to establish any such program or
plan.  Employee shall be entitled to such vacations and to reimbursement of
such expenses as UST's or USTC's policies allow to all employees having
comparable responsibilities and duties.  So long as such additional benefits
are payable out of or accrue to "AM's Share of Revenues" as hereinafter
defined, the Employee/Principals may provide additional executive benefits to
themselves in addition to those provided by UST, provided that no such benefit
be qualified under Section 401 of the Internal Revenue Code or non-qualified
(under Section 401 of the Internal Revenue Code) pursuant to the terms of a
plan or arrangement which operates in a manner that is substantially similar or
mirrors a qualified plan, and provided further that the award of any such
benefits does not increase the cost to UST of providing benefits to UST
employees who are not employees of AM.

         SECTION 10.  REVENUE SHARING PROVISION.  The purpose of this
Revenue Sharing Provision is to provide UST with an acceptable stream of income
and to permit AM to retain a specified percentage of its revenues for use by
Employee/Principals, including the Employee, in their discretion in paying
expenses of operation, including compensation.  It is intended to allow the
Employee and the other Employee/Principals to be compensated for enhancing and
growing AM's revenues in a substantial manner and to make operating decisions
freely within the limits of "AM's Share of Revenues," as such term is defined
below.  See Schedule V for examples of Revenue Sharing calculations.

         (a)     ALLOCATION OF REVENUES.  "Base Annual Revenues of AM" in 1994
and all subsequent years for purposes of this Revenue Sharing Provision shall
be AM's actual 1994 Revenues less $750,000, such total amount to be
appropriately modified to reflect changes in the United States Bureau of Labor
Statistics Cost of Living Index for the Boston Metropolitan Statistical Area or
any designated successor index for 1995 and all subsequent years.  The term
"Revenues" shall mean AM's revenues calculated on an accrual basis in
accordance with GAAP, (excluding shared revenues paid to investment or other
firms or professionals and generated from AM clients), consistent with USTC's
usual practice.

         During the pro-rated six month period commencing July 1, 1994 and
         ending December 31, 1994, and for each calendar year and for portions
         thereof on a pro-rated basis thereafter, AM shall retain sixty percent
         (60%) ("Base AM Retention"), of AM's pro-rated actual Revenues and AM
         shall make available to USTC for distribution to UST forty percent
         (40%) ("Base UST Amount"), subject to adjustment as set forth in this
         Section 10(a).

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar of AM's annual revenues
         over Base Annual Revenues of AM, AM shall retain an additional $.40,
         and an additional $.60 shall be allocated to UST, provided that in no
         event shall UST's Share of Revenues exceed fifty percent (50%) of
         actual Annual Revenues of AM.

         In 1995 and for each calendar year and for portions thereof on a
         pro-rated basis thereafter, for each dollar that actual Annual
         Revenues of AM are less than Base Annual Revenues of AM, Base AM
         Retention shall be reduced by $.40 and the Base UST Amount shall be
         reduced by $.60, provided that in no event shall UST's Share of
         Revenues be less than thirty percent (30%) of Annual Revenues of AM.

         Amounts retained by AM as aforesaid are herein referred to as "AM's
Share of Revenues".  Amounts allocated to UST as aforesaid are herein referred
to as "UST's Share of Revenues".

                                      9
<PAGE>   10
         (b)     FLOOR INCENTIVE.  In addition, during the Original Term of
this Agreement (thirty months), AM shall retain a "Floor Incentive" of $40,000
per month from "UST's Share of Revenues" ($1.2 million in the aggregate).  The
"Floor Incentive" shall be accrued by USTC and paid pursuant to subsection
(d)(iv) hereof, and shall be excluded from the limitations of Section 5(a)(iv)
of this Agreement.  In the event of a material breach by UST or USTC of this
Agreement during the Original Term (which breach is not cured during the
applicable grace period and is either confirmed by the arbitrator under Section
18 hereof or not contested by UST or USTC), the Employee/Principals (for
distribution in accordance with the Unifying Agreement) may elect to receive an
aggregate lump-sum payment determined by multiplying (x) the monthly "Floor
Incentive" by (y) the remaining months in the Original Term.  If a "Triggering
Event" occurs during the period January 1, 1995 through June 30, 1998, the
aggregate Floor Incentive, net of tax, accrued during the four full calendar
quarters next preceding the date of the Triggering Event, shall not be deducted
from "AM's After Tax Revenues" for purposes of calculating the Section 11
Formula Payment.  Moreover, if a Triggering Event occurred before all Floor
Incentives have been paid, UST or USTC's successor shall assume responsibility
to make the remaining Floor Incentive payments.

         (c)     SPECIAL PROVISIONS.  It is understood and agreed that:

                 (i)      The balance of "Base AM Retention" for the period
                          July 1, 1994 through December 31, 1994 shall be paid
                          by UST or USTC to AM no later than February 15, 1995.

                 (ii)     All amounts due to Robert B. Zevin pursuant to his
                          agreement dated September 30, 1994 with USTC shall be
                          considered as expenses to come out of "AM's Share of
                          Revenues" in each year in accordance with the
                          Unifying Agreement.

                 (iii)    The application of this Section may make it
                          unattractive for AM to enter a business activity with
                          a profit margin of less then 40%.  Accordingly, the
                          parties have agreed to negotiate separate "side
                          letters" with respect to revenue sharing on any new,
                          lower-margin business opportunities identified in the
                          future by AM and regarded as worthy of pursuit by UST
                          and/or USTC.

                 (iv)     The parties hereto further understand and acknowledge
                          that the term "Revenues" as used herein is intended
                          to cover revenues of AM as they now exist and as they
                          may grow or contract internally, and not revenues
                          from the acquisition by UST or USTC of another
                          investment advisory firm concerning which the parties
                          hereto agree to negotiate in good faith as to revenue
                          sharing.

                 (v)      The investment return on allocated, but unexpended,
                          portions of AM's Share of Revenues shall be measured
                          at the end of each calendar quarter by multiplying
                          the average of the month end balances during such
                          quarter by the published thirteen week U.S. Treasury
                          Bill Rate at the end of such calendar quarter.This
                          interest income shall be added to "AM's Share of
                          Revenues".

         (d)     Transfer of Revenues to UST; Retention of Revenues by
                 -----------------------------------------------------
                 USTC; Compensation of Employee/Principals.
                 ------------------------------------------

                 (i)      The Employee/Principals and AM shall use AM's Share
                          of Revenues to pay and provide for AM's business
                          expenses and expenditures including, without
                          limitation, investment in AM's business and new
                          products (see Section 6(d) above) and salaries of its
                          employees, except that any federal, state or local
                          income tax to which USTC is subject shall be the
                          responsibility of UST and shall not be treated as a
                          business expense of AM.

                 (ii)     The Employee/Principals shall incur no expenses or
                          obligations on behalf of AM which exceed USTC's
                          ability to pay or provide for them when due out of
                          AM's Share of Revenues.  The Employee/Principals
                          shall not incur obligations or make binding
                          commitments on behalf of USTC or UST not related to
                          AM's business and requiring expenditures by USTC in
                          excess of $50,000, or make representations to third
                          parties that they have the authority to do so.
                          However, the Employee/Principals may represent and
                          advertise that AM is a division of USTC and an
                          affiliate of UST, and other than as limited above in
                          this Section 10 (d)(ii), may incur obligations or
                          make binding commitments on behalf of USTC in the
                          ordinary course of business.

                 (iii)    The Employee/Principals may (subject to Policies and
                          applicable laws and regulations) pay to AM's
                          employees, including the Employee and the other
                          Employee/Principals, at times and in amounts and
                          proportions determined in accordance with the
                          Unifying Agreement, the balance of AM's Share of
                          Revenues remaining after the payment of all of the
                          amounts required under subsection (d)(i) hereof and
                          subject to Section 5(a)(iv).

                  (iv)    The Employee's Revenue Sharing compensation out of
                          "AM's Share of Revenues" shall be allocated in
                          accordance with the terms of the Unifying Agreement.
                          The Employee/Principals have provided to UST and USTC
                          in the Unifying Agreement their procedures for
                          determining changes, if any, in the allocation of





                                      11
<PAGE>   12
                          Revenues among the Employee/Principals.  If an
                          Employee/Principal chooses to leave USTC's employ
                          after bypassing this change determination mechanism
                          or refusing to abide by its results, the
                          Employee/Principal shall be deemed to have committed
                          a material breach of this Employment Agreement.

                 (v)      The Employee/Principals and AM shall make available
                          to UST, UST's Share of Revenues upon reasonable
                          request by UST and action by USTC's Board of
                          Directors.  The Employee/Principals shall not spend
                          or incur obligations to spend any part of UST's Share
                          of Revenues.

         (e)     ADMINISTRATION.  The parties hereto and the other
Employee/Principals agree to meet and consult to endeavor in good faith to
agree on appropriate procedures, in addition to Policies and applicable laws
and regulations,  for administering the provisions of this Section 10.

         The Employee/Principals shall retain control over all expenditures of
AM, subject to the power of USTC's Board of Directors to exercise its rights
under Section 5A, and subject to this Revenue Sharing Provision, and
recognizing that AM is a division of USTC.

         (f)     TERM AND STATUS AS PARTIES.  This Revenue Sharing Provision
shall continue in effect until terminated by agreement of UST, USTC, and the
Employee/Principals acting in accordance with the Unifying Agreement.  If the
employment of Employee by USTC ceases other than as a result of a material
breach by UST or USTC of this Employment Agreement, such Employee shall
thereupon automatically cease to be a party to this Revenue Sharing Provision
and to have any rights or obligations under this Section, and shall cease to be
an Employee/Principal for the purposes of this Provision.  Nothing  in this
Employment Agreement shall be construed to grant to the Employee any right to
be employed by USTC beyond the terms of this Employment Agreement.

         SECTION 11.      FORMULA PAYMENT.  If Employee is still employed by
USTC at the time of a "Triggering Event" (as hereinafter defined), the Employee
shall receive Employee's share of a formula payment (the "Formula Payment") as
follows:

         (a)     Unless otherwise agreed by the Employee/Principals acting in
accordance with the Unifying Agreement, the Employee's share of the Formula
Payment shall be the percentage set forth after the Employee's name on Schedule
III hereto;

         (b)     The "Formula Payment" shall be 3.33 times "AM's After Tax
Revenues" (as hereinafter defined and meaning generally UST's Share of Revenues
minus taxes);





                                      12
<PAGE>   13
         (c)     "AM's After Tax Revenues" shall be the portion of AM's
after-tax Revenues contributed, accruing or allocated to UST for the four full
calendar quarters next preceding the date of the Triggering Event; determined
in accordance with GAAP consistently applied in such periods.  For purposes of
this Subsection, there shall be assumed a combined federal and state tax rate
of 38%, such rate to be appropriately adjusted to reflect changes in applicable
federal and state corporate tax rates.  An example of this calculation is set
forth on Schedule V.

         (d)     The Formula Payment shall be adjusted in accordance with
Schedule IV hereto for gain or loss of AM clients between the signing of a
definitive merger, consolidation or acquisition agreement or an agreement
related to another Triggering Event and the Closing Date related to any such
Triggering Event.

         (e)
                 (i)      At the Closing Date of a Triggering Event, three Key
                          Employees shall be identified as follows.  For every
                          person who has been an Employee/Principal at any time
                          during the previous 15 months there shall be
                          calculated a Weighted Average Share equal to the sum
                          of (a) the share of the Formula Payment such person
                          was entitled to receive from time-to-time during the
                          preceding 15 months in accordance with Schedule III
                          and subsequent changes thereto by the
                          Employee/Principals acting in accordance with the
                          Unifying Agreement times (b) the number of days such
                          person was entitled to each such share.  The three
                          persons among those who are or have been
                          Employee/Principals on the Closing Date of the
                          Triggering Event or during the previous 15 months who
                          have the three highest Weighted Average Shares shall
                          be deemed the "Key Employees".

                 (ii)     If only one of the three Key Employees is no longer
                          in the employ of USTC as of the Closing Date of such
                          Triggering Event, then all of that Key Employee's
                          Weighted Average Share of the Formula Payment
                          (expressed by X%) shall be placed in escrow in the
                          manner contemplated by Section 11(f). To determine
                          the distribution of each of the three escrowed
                          installments use the following formula.  Revenues of
                          AM (as defined in Section 10(a)) for the last full
                          calendar year prior to a Triggering Event should then
                          be determined (the "Measuring Year").  Such Revenues
                          of AM for the Measuring Year multiplied by a decimal
                          representing 100% - X% equals the "Minimum Revenues".
                          If during the next full calendar year following the
                          Measuring Year, Revenues of AM are equal to or less
                          than Minimum Revenues none of the one-third of the
                          escrowed amount for such year will be paid to the
                          remaining Employee/Principals in accordance with this
                          Section and all of it will be retained by UST's or
                          USTC's successor.  If Revenues of AM for





                                      13
<PAGE>   14
                          that calendar year exceed Minimum Revenues, (i) take
                          the U.S. Dollar amount of such excess above the
                          Minimum Revenues and divide it by the Revenues of AM
                          for the Measuring Year minus the Minimum Revenues,
                          (ii) then multiply the resulting fraction by
                          one-third of the full escrowed amount, (iii) the
                          product of the foregoing formula should be delivered
                          to the remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and the remainder of that installment
                          should be retained by UST or UST's successor.
                          Similar calculations should be made for the second
                          and third installments, but in each case using the
                          same Minimum Revenues.

                 (iii)    If two or more of the Key Employees are no longer in
                          the employ of USTC as of the Closing Date of such
                          Triggering Event, then 100% of the Formula Payment
                          shall be placed in escrow in the manner contemplated
                          by Section 11(f).  To determine the distribution of
                          each of the three escrowed installments use the
                          following formula.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment equal or exceed
                          Revenues of AM for the Measuring Year, all of that
                          escrowed installment should be distributed to the
                          remaining Employee/Principals as a group for
                          distribution in accordance with the Unifying
                          Agreement and none should be retained by UST or
                          USTC's successor.  If Revenues of AM for the last
                          full calendar year prior to the distribution date of
                          the applicable escrow installment are less than
                          Revenues of AM for the Measuring Year, divide the
                          U.S. Dollar amount of Revenues of AM for such last
                          full calendar year by the U.S. Dollar amount of
                          Revenues of AM for the Measuring Year and multiply
                          the resulting fraction by one-third of the full
                          escrowed amount.  The product of the foregoing
                          calculation should be delivered to the remaining
                          Employee/Principals as a group for distribution in
                          accordance with the Unifying Agreement and the
                          remainder should be retained by UST's or USTC's
                          successor.

         (f)     Seventy percent (70%) of the Employee's share of the Formula
Payment shall be paid in cash within twenty (20) days of the Closing Date of
the Triggering Event.  The remaining thirty percent (30%) shall be placed in
escrow with an escrow agent acceptable to both UST and Employee/Principals and
paid to the Employee or the Employee's estate as provided in Section 7(b) in
installments of one third of the escrowed amount at the end of years one, two
and three (which may not be calendar years) after the Closing Date of the
Triggering Event plus interest, at the interest rates on the date of the
Closing Date of the Triggering Event of one, two and three year Treasury
securities,  provided that at the time of each such installment payment, the
Employee has not been terminated with cause or for a material breach or has not
voluntarily ceased to be employed by AM.

         (g)     A "Triggering Event" shall be deemed to have occurred when:

                 (i)      there occurs the signing of a definitive agreement of
                          merger or consolidation of UST or USTC with any other
                          corporation, other than a merger or consolidation
                          which would result in the voting securities of UST or
                          USTC 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 USTC, or such surviving entity outstanding
                          immediately after such merger or consolidation;
                          provided, however, that a merger or consolidation
                          effected to implement a recapitalization,
                          reorganization or restructuring of UST or USTC (or
                          similar transaction) in which no "person" (as defined
                          in (g)(iii) below) acquires more than fifty percent
                          (50%) of the combined voting power of UST's then
                          outstanding securities shall not constitute a
                          Triggering Event; or

                 (ii)     there occurs a closing of a sale or other disposition
                          by UST of more than 50% of UST's, USTC's or AM's
                          business and assets; or

                 (iii)    any "person", as such term used in Section 13(d) and
                          14(d) of the Exchange Act other than UST or USTC or
                          any of their respective subsidiaries or affiliates or
                          any trustee or other fiduciary holding securities
                          under an employee benefit plan of either of them or
                          any of their subsidiaries or 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
                          50% percent or more of the combined voting power of
                          UST's or USTC's then outstanding securities.

         If (i) more than 50% of UST's then outstanding common stock or assets
are acquired by a "person" whose consolidated assets prior to the Triggering
Event were less than $4 billion or (ii) UST's business assets and operations
are consolidated with those of another bank or bank holding company and the
resulting entity has consolidated assets of $5.5 billion or less, a Triggering
Event shall be deemed to have occurred, but the length of the Phase II term of
employment of the Employee shall be increased automatically by one additional
year.

         (h)     If UST agrees to be acquired by an entity with a public image
so starkly negative that AM's affiliation with that entity would be reasonably
likely, by itself, to cause a loss of more than 25% of AM's gross revenues in
one year (unless the parties





                                      15
<PAGE>   16
mutually agree to the contrary), the Employee/Principals at their option acting
pursuant to the terms of the Unifying Agreement (and provided such right is
exercised within 30 days of the public announcement of such acquisition) will
be relieved of all of the Employee's obligations under the Phase II Term and no
Formula Payment will be made.

         (i)     The parties acknowledge that any such Formula Payment is
intended to compensate the Employee for: (i) the automatic extension of this
Agreement occurring by reason of a Triggering Event; (ii) the Phase II
Non-Competition covenants specified in Section 12; and (iii) the loss of
opportunity to make up for reduced rate of compensation which such Employee
earned with USTC for periods prior to the effective date of this Agreement.

         SECTION 12.      PHASE II NON-COMPETITION COVENANTS.

         (a)     During the longer of the Phase II Term (as defined in Section
4) if Phase II shall commence while Employee is employed by USTC hereunder or
while Employee is employed by USTC during or after such Phase II Term
hereunder, Employee shall not, except in the course of his employment with
USTC, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, stockholder,
                          consultant, adviser, subsidiary, affiliate,
                          independent contractor or otherwise, investment
                          advisory services to any person or entity;

                 (ii)     Interfere with AM's relations with any person or
                          entity who at any time during such period was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person, other than by
                          discharge of such person as a part of Employee's
                          duties.

         (b)     Until one year following the end of the Phase II Term, if the
Phase II Term should commence while Employee is employed by USTC hereunder or
one year following the termination of Employee's employment with USTC during or
after such Phase II Term, Employee shall not, directly or indirectly:

                 (i)      Provide or offer or attempt to provide, whether as an
                          officer, director, employee, partner, independent
                          contractor or otherwise, investment advisory services
                          to any person or entity who as of the date of the
                          termination or expiration of Employee's employment





                                      16
<PAGE>   17
                          with USTC was or had been a Client (which means       
                          Past, Present, and Potential Client);

                 (ii)     Interfere with AM's relations with any person or
                          entity who as of the date of the termination or
                          expiration of Employee's employment with USTC was a
                          Client (which means Past, Present, and Potential
                          Client); or

                 (iii)    Induce or attempt to induce directly or indirectly
                          any professional employee of AM to terminate his or
                          her employment or hire or attempt to hire, directly
                          or indirectly, any such person.

         (c)     Notwithstanding the provisions of subsections (a)(i) and
(b)(i), the Employee may render without compensation investment advisory
services to any immediate member of Employee's family, which shall include the
Employee and any trust or account which is comprised entirely of assets held
for the benefit of such Employee and/or immediate members of such Employee's
family, and may engage in such other activities as are listed on Schedule I
hereto.

         (d)     Employee and USTC agree that the periods of time and the
unlimited geographic area applicable to the covenants of this Section 12 are
reasonable, in view of the receipt and expected receipt of the Employee's share
of Revenue Sharing as provided in Section 10(c), and other compensation, and
the Formula Payment provided herein; the geographic scope and nature of the
business in which AM is engaged; Employee's knowledge of AM's business; and
Employee's relationships with AM's investment advisory clients.  However, if
such period or such area should be adjudged unreasonable in any judicial
proceeding, then the period of time shall be reduced by such number of months
or such area shall be reduced by elimination of such portion of such area, or
both, as are deemed unreasonable, so that this covenant may be enforced in such
area and during such period of time as are adjudged to be reasonable.

         SECTION 13.      ALL BUSINESS TO BE THE PROPERTY OF USTC; ASSIGNMENT
OF INTELLECTUAL PROPERTY.  During the Phase II Term if Phase II shall commence
while Employee is Employed by USTC hereunder and thereafter while Employee is
employed by AM and/or USTC:

         (a)     Employee agrees that any and all presently existing investment
advisory business of AM and all business developed by Employee or any other
employee of AM, including without limitation all investment advisory contracts,
fees, commissions, compensation records, Client Lists (as defined in Section
8), agreements, and any other incident of any business developed or sought by
AM or earned or carried on by Employee for AM, are and shall be the exclusive
property of USTC for its sole use, and (where applicable) shall be payable
directly to USTC.





                                      17
<PAGE>   18
         (b)     Employee hereby grants to USTC (without any separate
remuneration or compensation other than that received by Employee from time to
time in the course of his or her employment) Employee's entire right, title,
and interest throughout the world in and to, all research, information, Client
Lists, and all other investment advisory, technical and research data made,
conceived, developed and/or acquired by Employee solely or jointly with others
during the period of Employee's employment by USTC, which relate to investment
advice as it was or is now rendered or as it may, from time to time, hereafter
be rendered or proposed to be rendered, but excluding such individual's ideas
and thought processes which are not embodied in written or machine readable
form (all such non-excluded items being referred to as "Intellectual
Property").

         SECTION 14.      CONFIDENTIALITY.  Except in performance of services
for USTC, Employee shall not, either during the Phase II Term if Phase II shall
commence while the Employee is employed by USTC hereunder or thereafter while
employed by AM and/or USTC, use for Employee's own benefit or disclose to or
use for the benefit of any person outside USTC, any information not lawfully
available to the public concerning any Intellectual Property, including Client
Lists, whether Employee has such information in his or her memory or embodied
in writing or other tangible form.  All such Intellectual Property and such
information concerning Intellectual Property, and all originals and copies of
any Intellectual Property, and any other written material relating to the
business of AM, shall be the sole property of USTC.  During such Term or
thereafter, upon the termination of Employee's employment in any manner or for
any reason, Employee shall promptly surrender to USTC all originals and copies
of any Intellectual Property, and Employee shall not thereafter use any
Intellectual Property.

         The foregoing notwithstanding, Employee will have no obligation to AM
or USTC with respect to the disclosure or use of any Intellectual Property or
information concerning Intellectual Property if:

         (a)  Such Intellectual Property or information is or becomes publicly
known or otherwise enters the public domain through no wrongful act of
Employee; or

         (b)  Such Intellectual Property or information is received from a
third party which has no obligation to UST or USTC to maintain it in
confidence.

         Notwithstanding the references to Client Lists above, it shall not be
a violation of this Section or Section 13 hereof for Employee to communicate or
do business with any Past, Present or Potential Client in the course of
Employee's employment with AM and USTC, and any such conduct shall be limited,
if at all, solely by Section 12 hereof.

         SECTION 16.      ASSIGNABILITY.  This Employment Agreement shall be
binding upon and inure to the benefit of UST, USTC, and to any person or firm
who may succeed to the business of UST, USTC, or AM.  This Employment Agreement
shall not be assignable by Employee, but it shall inure to the benefit of
Employee's heirs, executors, administrators and legal representatives.

         SECTION 17.      ENTIRE AGREEMENT.  This Employment Agreement and the
Unifying Agreement contain the entire agreement between USTC and Employee with
respect to the subject matter hereof, and supersede all prior oral and written
agreements between any of UST, USTC, AM and the Employee with respect to the
subject matter hereof, including without limitation any oral agreements
relating to compensation.

<PAGE>   20
         SECTION 18.      ARBITRATION.  In the event the parties hereto
disagree as to whether a material breach has occurred of: (i) the "Independence
Assurances" under Section 5; (ii) USTC's right of termination of Employee's
employment under Section 7; (iii) this Agreement by USTC as described in
Section 19 (b); (iv) the revenue sharing provisions of Section 10; or (v) the
formula payment provisions of Section 11, such dispute shall be settled by
arbitration before a single arbitrator to be then named by UST and a majority
of the Employee/Principals acting in accordance with the Unifying Agreement, in
Boston, Massachusetts in accordance with the Commercial Arbitration Rules of
the American Arbitration Association.  If such arbitrator cannot serve, then a
successor shall be appointed in accordance with such Rules.  If the arbitrator
finds that there has been a material breach (and such breach has not been cured
by UST or USTC within sixty (60) days of such finding or by Employee in
accordance with Section 7 hereof), then the remedies provided for in Section 19
shall become available, as appropriate.

         SECTION 19.      EQUITABLE RELIEF AND OTHER REMEDIES.

         (a)  Employee recognizes and agrees that UST's, USTC's or the
Employee/Principals' remedies at law for any breach of the provisions of
Sections 12, 13 and 14 hereof would be inadequate and that for breach of such
provisions UST, USTC and the Employee/Principals  shall, in addition to such
other remedies as may be available to any of them at law or in equity or as
provided in this Employment Agreement, be entitled to injunctive relief and to
enforce their respective rights by an action for specific performance to the
extent permitted by law, and to the right of set-off against any amounts due to
the Employee by UST, USTC or AM.  Should Employee engage in any activities
prohibited by this Employment Agreement, he or she agrees to pay over to USTC
or UST all compensation received in connection with such activities.  Such
payment shall not impair any other rights or remedies of UST, USTC or AM or
affect the obligations or liabilities of Employee under this Employment
Agreement or applicable law.

         (b)  Any termination by USTC of Employee's employment which is not
authorized by Section 7 hereof shall constitute a material breach of this
Agreement.  In the event of a material breach of this Agreement by UST or USTC
which is not cured pursuant to Section 18, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, USTC
shall pay Employee the Employee's then current Annual Base Salary for a period
equal to the greater of (i) twelve months or (b) the balance of the then
current term of this Agreement.  Any such payments shall not constitute part of
AM's Share of Revenues.  Should such a material breach occur and not be so
cured, the Employee shall be  free to compete, Sections 12, 13 and 14 shall not
apply and the Employee shall leave with the rights described in Section 5(b) of
this Agreement.

         (c)  Without limiting the generality of the foregoing, the parties 
expressly agree





                                       20
<PAGE>   21
that termination without cause of Employee's employment hereunder during the
Phase II Term by UST, USTC or any other person or entity will constitute a
material breach of this Agreement and, in addition to any other rights or
remedies which the Employee may have, at law, in equity or otherwise, shall
give Employee the right to salary continuation as set forth in Section 19(b)
hereof.

         SECTION 20.      WAIVERS AND FURTHER AGREEMENTS.  Neither this
Employment Agreement nor any term or condition hereof, including without
limitation the terms and conditions of this Section 20, may be waived in whole
or in part as against UST, USTC, AM or Employee except by written instrument
executed by each of them, expressly stating that it is intended to operate as a
waiver of this Employment Agreement or the applicable term or condition hereof.
Each of the parties hereto agrees to execute all such further instruments and
documents and to take all such further action as the other party may reasonably
require in order to effectuate the terms and purposes of this Employment
Agreement as stated herein.  Furthermore, no waiver may violate the terms of
the Unifying Agreement and any waiver shall require action of the
Employee/Principals in accordance with the Unifying Agreement authorizing such
waiver.

         SECTION 21.      AMENDMENTS.  This Employment Agreement may not be
amended, nor shall any parties be added hereto, nor any change, modification,
consent, or discharge be effected except by written instrument executed by all
three of the Employee, USTC and UST.  Furthermore, no amendment or modification
may violate the terms of the Unifying Agreement and any amendment or
modification shall require action of the Employee/Principals in accordance with
the Unifying Agreement authorizing such amendment or modification.

         SECTION 22.      SEVERABILITY.  If any provision of this Employment
Agreement shall be held or deemed to be invalid, inoperative or unenforceable
in any jurisdiction or jurisdictions, because of conflicts with any
constitution, statute, rule or public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision in question
unenforceable in any other jurisdiction or in any other case or circumstance or
of rendering any other provisions herein contained unenforceable to the extent
that such other provisions are not themselves actually in conflict with such
constitution, statute or rule of public policy, but this Employment Agreement
shall be reformed and construed in any such jurisdiction or case as if such
invalid, inoperative, or unenforceable provision had never been contained
herein and such provision reformed so that it would be enforceable to the
maximum extent permitted in such jurisdiction or in such case.

         SECTION 23.      NO CONFLICTING OBLIGATIONS.  Employee represents and
warrants to USTC and UST that Employee has no other interest or obligation
which is inconsistent or in conflict with this Employment Agreement or which
would prevent, limit, or impair, in any way, Employee's performance of any of
the covenants or duties

                               UNIFYING AGREEMENT

         THIS UNIFYING AGREEMENT made this 14th day of February, 1995 and
effective January 1, 1995, by and among United States Trust Company ("USTC"), a
banking and trust company having its principal place of business in Boston,
Massachusetts, UST Corp.  ("UST"), a Massachusetts corporation also having its
principal place of business in Boston, Massachusetts and the parent of USTC,
Domenic Colasacco of Needham, Massachusetts ("Colasacco"), Robert Lincoln of
Lincoln, Massachusetts ("Lincoln"), Stephen K. Moody of Cambridge,
Massachusetts ("Moody"), Lucia Santini of Mansfield, Massachusetts ("Santini")
and Robert B. Zevin of West Newbury, Massachusetts ("Zevin").

         Whereas, the Asset Management Division ("AM") is a division of USTC
which provides investment advisory and trust management services and each of
the initial Principals (as defined in Section 1.1 hereof and as listed on
EXHIBIT A attached hereto) is currently employed by AM and has simultaneously
with the execution and delivery of this Agreement entered into an Employment
Agreement as provided by Section 1.2 hereof;

         Whereas, the Principals are concerned that previous UST and USTC
practices have not allowed for enough spending to generate growth in AM's
business, or for fully competitive compensation for its principals;

         Whereas, UST and USTC desire to stabilize and increase the
profitability of AM and to pay its employees competitive compensation;

         Whereas, UST and USTC want to provide, and the Principals desire to
participate in, an incentive compensation program which reflects value created
in the AM business;

         Whereas, the Principals want to make it attractive to any potential
acquiror of UST, USTC or AM to protect existing relationships with AM employees
and clients, avoid re-writing existing client contracts, and further AM as a
separate business conducted under the name "United States Trust Company"; and

         Whereas, UST and USTC want, in a change of ownership situation, to
offer an opportunity to a prospective purchaser to retain the services of the
Principals and thereby receive a continuing stream of profits from AM;

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements hereinafter set forth and intending to be legally bound, the parties
hereby agree as follows:

ARTICLE I - PRINCIPALS

         Section 1.1. NAMES AND ADDRESSES. The names and mailing addresses of
the persons who will initially serve as Principals in accordance with the terms
of this Agreement are set forth in EXHIBIT A attached hereto and made a part
hereof. Principals may be added or removed in accordance with Sections 1.6 and
1.8 hereof. The term "Principal" as used in any provision of this Agreement
shall mean each initial Principal listed on EXHIBIT A


<PAGE>   2
attached hereto and each new Principal added in accordance with Section 1.6
hereof who, in each case, as of the date or at the time  of the event or period
relevant to such provision, shall be an offlcer of AM and a signatory to
this  Agreement and shall not have resigned or been removed as an officer of AM
or a Principal hereunder.

         Section 1.2. EMPLOYMENT AGREEMENTS. Concurrently with the execution of
this Agreement,  each of the initial Principals shall enter into an Employment
Agreement with USTC, joined in as to  certain matters by UST, in substantially
the form of EXHIBIT B hereto.

         Section 1.3. THE PRINCIPALS COMMITTEE. The business of AM shall be
managed by a  committee of the then serving Principals (the "Principals
Committee") which shall have and may  exercise all the powers of AM except as
otherwise reserved to the Senior Principal, USTC or UST  by this Agreement.

         Section 1.4. VOTING. Each Principal shall have one vote on all matters
to be voted on by the Principals Committee hereunder.

         Section 1.5. DUTIES OF THE PRINCIPALS. The Principals shall have such
duties as are set forth in  their respective Employment Agreements and this
Agreement. Whenever called upon under this  Agreement or under the Employment
Agreement, the Principals Committee shall act by vote of a  majority of the
Principals, unless a vote of a Super-Majority (as defined in Section 1.6.
hereof) is  required under this Agreement.

         Section 1.6. ELECTION OF A NEW PRINCIPAL. The Principals Committee, by
vote of seventy percent  (70%) of the Principals (a "Super-Majority"), may
elect a new Principal. At the time of such election, the  Principals Committee,
in accordance with Section 5.2(c), shall decide on the percentage of the
Formula  Payment (as defined in the form of Employment Agreement attached
hereto as EXHIBIT B and any  amendment thereto) to allocate to such new
Principal. Such person shall then become a Principal for all  purposes
hereunder and a party to this Agreement upon execution of a counterpart of this
Agreement,  countersigned by the Senior Principal, and an Employment Agreement
with USTC and UST substantially in the form of EXHIBIT B attached hereto, with
an appropriately amended Schedule III attached.

         Section 1.7. TERM. Each Principal shall remain a Principal until (i) he
dies, resigns, is removed  or becomes disqualified, (ii) his Employment
Agreement is terminated with or without cause, or (iii)  this Agreement is
terminated with or without cause pursuant to Article VI hereof.

         Section 1.8. REMOVAL OF A PRINCIPAL. The Principals Committee, by vote
of a SuperMajority  of the Principals, may instruct USTC to terminate, with or
without cause, a Principal's employment by  USTC and of the related Employment
Agreement.

         (a) If a Principal is terminated by the Principals Committee without
cause pursuant to this  Section 1.8, (i) the Principal shall be entitled to
payment by AM of the greater of (A) the amount of  compensation that such
Principal would have received under Section 3.1


<PAGE>   3
hereof for the remainder of the then current term of the Principal's Employment
Agreement, or (B) an amount equal to such Principal's  then current Annual Base
Salary (as defined in Section 3.1) and (ii) the Principal's Employment
Agreement with UST and USTC (including, without limitation, Sections 12, 13 
and 14 thereof) shall immediately terminate and the Principal shall be free to
compete with AM's business. The amounts payable to the terminated Principal
under this Section 1.8(a) shall be paid at such  times and in such amounts as
would otherwise have been required under the terms of such Principal's 
Employment Agreement UNLESS the Principals Committee, by vote of a
Super-Majority of the Principals  (with the terminated Principal excluded from
voting), decides to accelerate payment of the amounts due  hereunder.

         (b) If a Principal is terminated by the Principals Committee for cause
pursuant to this Section  1.8, AM's obligations to pay further compensation
hereunder and under such Principal's Employment  Agreement shall cease as of
the date of termination, except that any amounts theretofore accrued under
Section 3.1 hereof shall be paid when due to the Principal, and the provisions
of the Principal's  Employment Agreement with UST and USTC shall immediately
terminate (except for the provisions of  Sections 12 (b), 12(c), 12(d), 13 and
14 thereof).

         (c) As used herein, "cause" shall mean (i) any material breach by a
Principal of his Employment  Agreement; (ii) any act by a Principal causing a
material breach of AM's duties to UST and USTC under  Section 10 of such
Principal's Employment Agreement; (iii) the conviction of a Principal for a
crime  involving moral turpitude; or (iv) willful misconduct in the performance
by a Principal in connection with  the Principal's duties under such
Principal's Employment Agreement after due notice and reasonable opportunity to
correct such conduct.

         Section 1.9. DISABILITY. The Principals Committee, by vote of a
Super-Majority of the Principals,  may terminate a Principal's employment upon
thirty (30) days' notice to such Principal if such Principal  should be unable,
for one or more periods aggregating four (4) months during any consecutive
twelve (12)  month period, because of illness, accident, or other disability
(mental or physical), to discharge  substantially all of his duties hereunder,
and such disability shall be continuing at the time of such notice.  After any
such termination, AM shall continue to pay such Principal for three (3)
consecutive months at  his then current salary rate, UNLESS the Principals
Committee, by vote of a Super-Majority of the  Principals, decides to increase
or otherwise change the amounts to be paid to any such disabled Principal
hereunder. The foregoing amounts and any additional amounts paid to such
disabled Principal hereunder  shall be paid out of AM's Share of Revenues (as
defined in the form of Employment Agreement attached  hereto as EXHIBIT B and
any amendment thereto).

         Section 1.10. DEATH OF A PRINCIPAL. In the event of a Principal's death
during the term of this  Agreement, AM's obligations to pay further
compensation hereunder and under such Principal's  Employment Agreement shall
cease as of the date of death, except that any amounts theretofore accrued
under Sections 3.1 and 3.2 hereof shall be paid when due to the Principal's
estate, UNLESS the Principals  Committee, by vote of a Super-Majority of the
Principals, decides to increase or otherwise change the total amounts to be
paid to any such deceased Principal hereunder. The foregoing amounts and any
additional amounts paid to such deceased Principal hereunder shall be paid out
of AM's Share of  Revenues (as defined in the form of Employment Agreement
attached hereto as Exhibit B and any  amendment thereto).

         Section 1.11. RESIGNATION OF A PRINCIPAL. In the event that a
Principal resigns, AM's
<PAGE>   4
obligations to pay further compensation hereunder shall cease as of the date of
such resignation, except that any amounts theretofore accrued under Section 3.1
hereof shall be paid when due to the Principal.

ARTICLE II - SENIOR PRINCIPAL

         Section 2.1.  NOMINATION AND ELECTION OF THE SENIOR PRINCIPAL. On an
annual basis, the Principals Committee, by vote of a majority of the
Principals, shall nominate a person from among the Principals to be the Senior
Principal of AM. Such person shall serve as Senior Principal of AM unless his
nomination is vetoed by vote of USTC's Board of Directors taken within 60 days
of notification of such nomination. Colasacco shall serve as the Senior
Principal of AM for the term beginning January 1, 1995 and until his successor
is duly elected and qualified. No person elected under this Section 2.1. to
serve as the Senior Principal shall be precluded from serving more than one
term.

         Section 2.2.  REMOVAL OF THE SENIOR PRINCIPAL. During his term, the
Principals Committee may remove, with or without cause, a Principal as the
Senior Principal, by vote of a Super-Majority of the Principals.

         Section 2.3.  POWERS OF THE SENIOR PRINCIPAL. Subject to Section 2.5
hereof and the other terms and conditions of this Agreement, the Senior
Principal shall have general supervision and control over AM's business.
Recognizing that AM is a division of USTC, the Senior Principal shall control
all expenditures of AM subject to (i) the power of USTC's Board of Directors to
exercise its rights under Section 5A of the form of Employment Agreement
attached hereto as EXHIBIT B and any amendment thereto, (ii) the Revenue
Sharing Provision contained in Section 10 of the form of Employment Agreement
attached hereto as EXHIBIT B and any amendment thereto and (iii) approval by
the Principals Committee if required pursuant to the terms of this Agreement.

         Section 2.4.  DUTIES OF THE SENIOR PRINCIPAL. The Senior Principal 
shall represent and act on behalf of AM on all matters, except those matters
specifically reserved to the Principals Committee under this Agreement and
those matters that may be delegated by the Senior Principal or the Principals
Committee hereunder. Without limiting the generality of the foregoing, whenever
a consent or approval of the Principals shall be required under any Employment
Agreement or this Agreement, the Senior Principal or, in the Senior Principal's
absence, another Principal designated in writing by the Principals Committee,
shall communicate any consent or approval authorized by the Principals.

         Section 2.5.  ISSUES REQUIRING THE PRINCIPALS COMMITTEE'S APPROVAL. The
Principals Committee, by a vote of a majority of the Principals, may require
that certain decisions of the Senior Principal be subject to prior approval of
the Principals Committee.

ARTICLE III - COMPENSATION OF THE PRINCIPALS

         Section 3.1.  ANNUAL BASE SALARY. Subject to the Revenue Sharing
Provision contained in Section

<PAGE>   5
10 of the form of Employment Agreement attached hereto as EXHIBIT B and any
amendment thereto, while employed by USTC under the Employment Agreement, each
of the Principals shall receive the annual base salary (the "Annual Base
Salary") set forth in EXHIBIT C attached hereto.

         Section 3.2.  INCENTIVE PAYMENTS. Subject to the Revenue Sharing
Provision contained in Section 10 of the form of Employment Agreement attached
hereto as EXHIBIT B and any amendment thereto, from time to time, but not less
than annually, the Senior Principal shall make recommendations to the
Principals concerning the incentive compensation payments that shall be paid by
AM to each of the Principals, including the Senior Principal. Unless a majority
of the Principals agree to a different incentive compensation payment
arrangement, the recommendations of the Senior Principal shall be implemented
in the manner proposed by the Senior Principal.

         Section 3.3.  THE ZEVIN AGREEMENT. The following provisions shall apply
with respect to the compensation to be paid to Zevin hereunder:

         (a) USTC and Zevin are parties to an Independent Contractor Agreement
for Consulting Services dated September 30, 1994 (the "Independent Contractor
Agreement"). During the Original Term, any Renewal Term and the Phase II Term
(as defined in Zevin's Employment Agreement) of Zevin's Employment Agreement,
Zevin shall be compensated by UST and USTC solely in accordance with Sections
3.1 and 3.2 and Article V hereof. During such Terms, the provisions of the
Independent Contractor Agreement shall not be in effect.  In the event of a
breach of Zevin's Employment Agreement or a breach of this Agreement by UST or
USTC, however, the provisions of the Independent Contractor Agreement shall
immediately be deemed to be in effect but shall not be effective retroactively.
If such an event shall occur, Section 3.3(b) hereof shall not apply.

         (b) If Zevin resigns or is removed as a Principal at or after the
expiration of the Phase II Term of Zevin's Employment Agreement, the terms and
conditions of the Independent Contractor Agreement shall immediately be in
effect, and he shall thereafter be entitled to payment of all amounts earned
under the Independent Contractor Agreement, subject to the following
limitations. The foregoing sentence notwithstanding, if Zevin received an
initial payment of a Formula Payment (as defined in Zevin's Employment
Agreement) during the term of his Employment Agreement, AM shall not be
obligated to begin payments to Zevin under Section 4 of the Independent
Contractor Agreement until the amount calculated under Section 4 of the
Independent Contractor Agreement for the period after such initial payment is
made, which amount would otherwise be paid to Zevin under the Independent
Contractor Agreement, exceeds seventy-five percent (75%) of such initial
payment (the "Base Amount"). The Base Amount shall be adjusted upward if Zevin
receives additional amounts of the Formula Payment from the escrow established
under Section 11(f) of the Employment Agreement. In such case, AM shall not be
obligated to begin payments to Zevin under Section 4 of the Independent
Contractor Agreement until the total amount which would otherwise be paid to
Zevin under the Independent Contractor Agreement exceeds seventy-five percent
(75%) of the new Base Amount. For purposes of determining amounts which would
otherwise be paid to Zevin under this Section 3.3(b), only those accounts that
have heretofore been designated as Zevin's accounts under the Independent
Contractor Agreement and their "successor accounts" (as defined in the
Independent Contractor Agreement) shall be used.

ARTICLE IV - COMPENSATION OF EMPLOYEES OF AM WHO ARE NOT PRINCIPALS

         Section 4.1.  ANNUAL BASE SALARY. Subject to the Revenue Sharing
Provision contained in

<PAGE>   6
Section 10 of the form of Employment Agreement as attached hereto as EXHIBIT B
and any amendment thereto, each employee of AM who is not a Principal (each a
"Non-Principal") shall receive an annual base salary to be determined by the
Senior Principal in his sole discretion.

         Section 4.2.  INCENTIVE PAYMENTS. Subject to the Revenue Sharing
Provision contained in Section 10 of the form of Employment Agreement as
attached hereto as EXHIBIT B and any amendment thereto, from time to time, but
not less than annually, the Senior Principal shall make recommendations to the
Principals concerning incentive compensation payments to be paid by AM to the
Non-Principals. Unless a majority of the Principals agree to a different
incentive compensation payment arrangement, the recommendations of the Senior
Principal shall be implemented in the manner proposed by the Senior Principal.

ARTICLE V - FORMULA PAYMENTS

         Section 5.1.  FORMULA PAYMENTS. If a Triggering Event (as defined in 
the form of Employment Agreement attached hereto as EXHIBIT B and any amendment
thereto) shall occur, UST shall be required to pay to the Principals then still
employed by UST a Formula Payment (as defined in the form of Employment
Agreement attached hereto as EXHIBIT B and any amendment thereto).

Section 5.2.  ALLOCATION OF THE FORMULA PAYMENT.

         (a) Unless modified in accordance with Section 5.2(c), the Formula
Payment shall be allocated among the Principals as follows:

<TABLE>
         <S>             <C>
         Colasacco        25%
         Zevin            20%
         Lincoln          15%
         Moody            10%
         Santini           5%
</TABLE>

The balance of the Formula Payment shall be allocated in accordance with
Section 5.2(b).

         (b) The Senior Principal shall make a recommendation to the Principals
Committee as to how any amounts not allocated under Section 5.2(a) should be
allocated among the Non-Principals and the Principals. Unless a majority of the
Principals agree to allocate such amounts in a different manner, the
recommendation of the Senior Principal will be implemented in the manner
proposed by the Senior Principal.

         (c) The Principals Committee, by a vote of a Super-Majority of the
Principals, may at any time modify the allocation of the Formula Payment set
forth in Section 5.2(a) hereof and Schedule III to the Employment Agreements.

         The Employment Agreements to be executed by each of the initial

authorize or take such action at a meeting. Participation in a meeting by means
of conference telephone or  similar communications equipment by means of which
all persons participating in the meeting can hear each other at the same time

         Section 8.4.  SUCCESSORS AND ASSIGNS. This Agreement shall inure to the
benefit of, and be  binding upon, UST, USTC, any person or firm which may

too large a geographic area or over too great a range of activities, it shall
be interpreted to extend only over the maximum period of time, geographic area
or range of activities as to which it may be enforceable. If any provision of
this Agreement shall be determined to be invalid, illegal or otherwise
unenforceable by any court of competent jurisdiction, the validity, legality
and enforceability of the other provisions of this Agreement shall not be
affected thereby. Except as otherwise provided in this paragraph, any invalid,
illegal or unenforceable provision of this Agreement shall be severable, and
after any such severance, all other provisions hereof shall remain in full
force and effect.
