ITEM 1.  BUSINESS
 
GENERAL DESCRIPTION OF BUSINESS
 
     UST Corp. (the "Company"), a bank holding company registered with the Board
of Governors of the Federal Reserve System (the "Federal Reserve Board"), was
organized as a Massachusetts business corporation in 1967. The Company is also
subject to examination by, and is required to file reports with, the
Commissioner of Banks of the Commonwealth of Massachusetts (the "Massachusetts
Commissioner"). 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,
directly or indirectly, all of the outstanding stock of three active nonbanking
subsidiaries, all Massachusetts corporations: UST Leasing Corporation, UST Data
Services Corp. and UST Capital Corp.
 
     Through its banking and nonbanking subsidiaries, the Company provides a
broad range of financial services, principally to individuals and small-and
medium-sized companies in New England. 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, 1993, the Company's total
assets were approximately $2.0 billion and USTrust, the lead bank, had over $1.9
billion or 93% 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 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
 
     The Company reported a loss of $20.1 million, or $1.31 per share, for 1993,
resulting primarily from a loan loss provision of $42.7 million in the second
quarter and writedowns of certain nonperforming assets. In addition, the Company
incurred net losses in each of the two preceding recent fiscal years. See Note
19 to Consolidated Financial Statements of the Company.
 
Proposed New Standards on Safety and Soundness -- Asset Quality
 
     Proposed regulations covering standards for safety and soundness at banks
and bank holding companies have been put forth by the Company's primary federal
banking regulators as required by Section 132 of the Federal Deposit Insurance
Corporation Improvement Act of 1991 ("FDICIA"). Included in the proposal are
standards (1) dealing with the maximum amount of classified assets an
institution may have and (2) defining a minimum earnings amount. Failure to meet
these standards would require the filing of a compliance action plan with and
acceptable to the Company's supervisory agencies. If the proposed regulations
were to be adopted in their present form, the Company would not have been in
compliance with the first standard at December 31, 1993. The federal banking
regulators have not publicly indicated at this time when passage of final
regulations in this area will occur or whether final regulations will be
substantially similar to those proposed.
 
     At December 31, 1993, the Company had approximately $49.3 million in
nonaccrual loans, $.5 million in accruing loans 90 days or more past due, $41.5
million in restructured loans, $19.5 million in other real estate
 
                                        1
<PAGE>   4
 
owned and $12 million in Special Mention loans 30 to 89 days past due and
accruing. In addition, the Company had approximately $185 million of accruing
commercial and real estate loans which, while current, have nonetheless been
classified as Special Mention or 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. The Substandard classification,
however, does not necessarily imply ultimate loss for each individual asset so
classified. Special Mention assets, 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.
 
     The risk ratings assigned to these loans were an important factor in the
Company's analysis of the adequacy of its reserve for loan losses. The
above-described, proposed regulations, if implemented in their current form,
however, may require the Company to reduce significantly the level of these
loans. Among the responses available to the Company, in this event, is a further
acceleration of the Company's strategy to handle problem credits expeditiously.
It is not possible to predict the future effects on the Company's financial
condition or results of operations of actions which may be taken by the Company
in response to final regulations in this area.
 
     Management of the Company has identified the reduction of the aggregate
amount of non-performing and classified assets as a high priority. Management
will continue to assess its alternatives with a view to implementing the most
effective means of achieving such reduction.
 
Potential Regulatory Sanctions
 
     Certain apparent and inadvertent violations of the insider lending
provisions (and related lending limit provisions) of Regulation O of the FRB
related to extensions of credit by USTrust to Director Francis X. Messina have
led the FDIC to require that corrective action be taken and to advise USTrust
orally that the FDIC may consider the imposition of civil money penalties with
respect to such matters. No FDIC representative has suggested to USTrust or the
Company that there was any willful or intentional misconduct on the part of
USTrust, Director Messina or USTrust's other institution-affiliated parties in
connection with these matters.
 
     To address these issues, USTrust and Director Messina have undertaken a
program to reduce the aggregate balance of Mr. Messina's outstanding loans from
USTrust and to improve the collateral support for the remaining outstanding loan
balance. The elements of this program have been communicated to and reviewed by
the FDIC. In furtherance of the program, since late 1993, the outstanding
principal of the aggregate loans to Director Messina and his related interests
has been reduced by more than $11 million from approximately $30 million to less
than $19 million, and such loans are now below all applicable lending limits. To
date, the Company has incurred no losses with respect to any of these loans,
although they are characterized as "Substandard" in the Company's internal risk
rating profile, and all such loans are current as to both principal and
interest.
 
     There has been no further action taken by any bank regulatory agency to
date. The FDIC has the authority to levy civil money penalties of various
amounts for violations of law or regulations, orders and written conditions and
agreements, which, depending upon the nature and severity of the violations, may
be, in situations where conduct has been egregious, as high as $1 million per
day for the period during which such violation continues. In connection with the
apparent violations described above, the FDIC has the authority to impose
penalties on any of USTrust, its Board of Directors, officers of the Bank,
Director Messina personally, "institution-affiliated parties" of USTrust or any
combination thereof.
 
     While it is not possible to predict with certainty the probability of
penalties being assessed, the person or persons upon whom any penalty would be
assessed or the amounts of any such penalties, were they to be assessed,
management of the Company believes that it is unlikely that this matter will
have a material adverse effect on the Company's financial condition or results
of operations. Consequently, no provision in respect of penalties has been made
in the Company's Consolidated Financial Statements. See Note 15 to Consolidated
Financial Statements of the Company.

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. In mid-1992 and
1993, UST/Conn agreed to two addenda to its 1991 stipulation and agreement with
the Connecticut 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 (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 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 I leverage capital ratios
at or in excess of 6%. Each of the Company's subsidiary banks is currently in
compliance with its respective capital requirements. As provided in the
Regulatory Agreements, the Company, USTrust and UST/Conn have instituted plans
to reduce levels of nonperforming assets and have developed 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. 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" below. For a discussion of related-party
transactions, see Note 14 to Consolidated Financial Statements.
 
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 and other specialized lending
services. USTrust also provides merchant credit card services. USTC provides
deposit services and other banking services, but focuses its activities on money
management 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, 1993, the combined lending
limit to a single borrower of the subsidiary banks was approximately $28
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 late 1993, the Company introduced a Choice Checking retail
account product which combines a relatively modest fee structure with ancillary
travel, insurance and other "lifestyle" benefits. 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. In 1993, the
Company introduced an Affordable Mortgage Program designed to provide certain
customers who may not qualify for traditional mortgage financing with an
alternate means of financing or refinancing a residence. The Company's banking
subsidiaries, which currently have an aggregate of 34 banking offices, maintain
an automated teller machine system which through membership in the NYCE, Cirrus
and Yankee 24 ATM networks provides the Company's customers with access to their
accounts at locations throughout the United States. 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.

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, profit-sharing
and other employee benefit trusts. At December 31, 1993, the total assets under
management of USTC were approximately $3.3 billion.
 
INVESTMENTS
 
     The subsidiary banks maintain securities portfolios consisting primarily of
U.S. Government Agency, corporate and municipal securities. USTrust's investment
portfolio also includes certain other equity investments as allowed within
limits prescribed by Massachusetts law. The Treasury Division of the Company
provides investment portfolio advisory services to its affiliated banks.
 
PRINCIPAL NONBANKING SUBSIDIARIES
 
     UST Leasing Corporation, organized in 1987 and a subsidiary of USTrust
provides a broad range of equipment leasing services to major corporations
headquartered throughout the United States. In 1994, UST Leasing Corporation
intends to develop a line of leasing products designed to meet the needs of the
Company's small business customers and other business entities with similar
needs.
 
     UST Data Services Corp., organized in 1981 and a subsidiary of USTrust
provides a full range of electronic data processing services to the Company and
its affiliates.
 
     UST Capital Corp., organized in 1961, was acquired by the Company in 1969,
is a subsidiary of USTC and is a licensed Small Business Investment Company. It
specializes in equity and long-term debt financing for growth-oriented
companies.
 
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 during
the past few years. During the past several years, acquisitions of small-and
medium-sized banks and bank holding companies by the largest New England bank
holding companies and the closing by regulators of a number of banks and bank
holding companies in Eastern Massachusetts and Connecticut has 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 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
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 Bank Holding Company Act
of 1956, as amended in 1970 (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 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. 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 examinations 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 a Connecticut subsidiary bank, or is
inconsistent with sound banking principles or the provisions of Chapter 658 (the
banking statute) of the Connecticut General Statutes.

     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, acceptance of 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. They were further increased for the first
half of 1993 and decreased in the second half of 1993 pursuant to regulations
issued under the Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA").
 
     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.
 
     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. See "Recent Developments -- Potential
Regulatory Sanctions."
 
     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 capital order or 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 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.

<PAGE>   9
 
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 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".
 
     New 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
 
                                        7
<PAGE>   10
 
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. See "Recent Developments -- Proposed New
Standards on Safety and Soundness -- Asset Quality."
 
     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 "satisfactory." 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 not yet determined whether it will continue
to examine USTC for CRA compliance.
 
     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.
 
     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 interstate branching and
expansion of bank powers. It is impossible to predict whether any of the
proposals will be adopted and the impact of such adoption on the business of the
Company or its subsidiaries.
 
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.
 
     The Company's primary loan market, the New England region, continues to
experience an uneven and slow recovery. 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. At
year-end 1993, the Company's exposure to credit risk for which the primary
source of repayment is real estate collateral included $499 million of loans.
Recent economic studies have concluded that the region's economy
 
                                        8
<PAGE>   11
 
will remain sluggish for at least the balance of this year. While there have
been pockets of growth, they have been rather anemic, and the forecast is for
small increases in the overall job market with some industries increasing
modestly and others not at all. Real estate prices and activity have both
improved somewhat from extremely depressed levels. See "Management's Discussion
and Analysis of Financial Conditions and Results of Operations" below.
 
GENERAL
 
     No significant portion of the 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, 1993, the Company and its subsidiaries employed
approximately 870 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 approximately 99% of the 89,014 square feet in
the building and the remaining space is leased as offices to a variety of
tenants.
 
     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 19,160 square feet of space at 25-55 Court
Street, Boston which is used primarily to house staff 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 two branch offices
in Huntington and Shelton, Connecticut. The remaining branch offices of the
Company occupy leased premises.
 
     The 1994 annual leasehold commitment for all premises leased by the
Company's subsidiaries totals approximately $4,031,000.
 
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, other than as noted in item 1 above under
"Recent Developments -- Potential Regulatory Sanctions" 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.

     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 2,091 at
January 31, 1994.
 
     There were no dividends declared during 1993 and 1992.
 
     Future dividends, including any extra cash dividends, will depend upon the
earnings of the Company and its subsidiaries, their need for funds, their
financial condition and other factors, including applicable government
regulations and regulatory consent. See "Recent Developments -- Bank Regulatory
Agreements and Orders" in Part I, Item 1. and the discussion of capital in
Management's Discussion and Analysis of Financial Condition and Results of
Operations on page 16 of this Form 10-K.
 
     In connection with the $20 million senior debt private placement
transaction of August 1986 (see Note 9 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 these provisions 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, 1993
 
INTRODUCTION
 
     The Company's primary loan market, the New England region, continues to
experience an uneven and slow recovery from the weak economic environment of
1990 to 1993. Recent economic studies have concluded that the region's economy
will remain sluggish for at least the balance of 1994. This climate has
contributed to the decline in commercial and residential real estate values,
although there is recent evidence that these values are stabilizing. Generally,
real estate prices and activity have both improved from extremely depressed
levels. Specifically, in the Commonwealth of Massachusetts, home sales and home
construction are both rising due to the prevailing low mortgage rates. The harsh
economic environment over the last few years has adversely affected both the net
worth of certain borrowing customers of the Company's subsidiary banks and the
Company's collateral position with respect to certain loans. Massachusetts has
seen both an exodus and failure of a number of businesses and unemployment
continues to remain high although somewhat lower than experienced during the
1990 to 1993 period. While there have been pockets of growth, they have been
sluggish, and the forecast is for small increases in the overall job market with
some industries increasing modestly and others not at all.
 
     The foregoing factors continued to influence the Company's financial
results for 1993, particularly in the areas of provision for loan losses and
expenses related to foreclosed asset and workout expense, and are likely to
continue to influence such results.
 
     This discussion should be read in conjunction with the financial
statements, notes, and tables included elsewhere in this Form 10-K. Certain
previous year numbers have been reclassified to conform with the 1993
presentation.
 
ASSETS
 
     Total assets of $2.04 billion at December 31, 1993 have declined slightly
from $2.18 billion at December 31, 1992. This was primarily caused by weak loan
demand in the Company's market area consistent with the sluggish local economy
and a reduction due to the chargeoffs of certain credits. As illustrated in the
table on page 24, almost all categories of loans decreased. See also "Credit
Quality and Reserve for Loan Loss" below.
 
     Presently, the Company does not plan a significant increase in assets.
Therefore, any increase in loans outstanding would likely be funded by the sale
of securities available-for-sale.
 
     Securities at $473.9 million remained essentially unchanged from December
31, 1992. In 1993, the Company adopted Statement of Financial Accounting
Standards No. 115 (SFAS 115), issued by the Financial Accounting Standards
Board. This Standard deals with the classification of all debt securities and
equity securities that have a ready market. According to SFAS 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. At December 31, 1993, all securities in the Company's
portfolio were classified as available-for-sale. This change in accounting
method resulted in an increase of $3.3 million to stockholders' equity,
representing the after-tax effect of the unrealized gain on securities
available-for-sale at December 31, 1993.
 
LIQUIDITY AND FUNDING
 
     Liquidity is defined as a company's ability to fulfill its existing and
anticipated financial obligations. It is provided either through the maturity or
sale of an entity's assets, such as loans and securities, liability sources such
as increased deposits and purchased or borrowed funds, or access to the capital
markets.
 
     At December 31, 1993, liquidity, which includes excess cash, excess funds
sold and unpledged securities totaled approximately $310 million or 15% of year
end assets, a $35 million increase from 1992.
 
                                       12

     The funds needed to support the Company's loan and securities portfolios
are provided primarily by UST Corp.'s retail deposits which are relatively low
cost and account for 73% of total deposits. The Company's deposits have
decreased $151 million, or 8.4% during 1993, in the present low interest rate
environment. Generally, high-yielding certificates of deposit which matured were
not renewed at the prevailing rates, as investors are utilizing mutual funds and
other non-bank vehicles to obtain higher returns. Short-term borrowings have
been increased $24 million, or 12%, to maintain needed liquidity.
 
     As shown in the Consolidated Statements of Cash Flow, cash and cash
equivalents decreased by approximately $26.3 million during 1993. This decrease
primarily reflected the use of $107.2 million for financing activities, offset
in part by $56.8 million in net cash provided by operations and $24.1 million
provided by investments. Net cash used for financing activities was primarily
the result of decreases in deposits offset in part by sales of common stock (see
below). Cash provided by operations resulted largely from net interest income
from loans (before provision for loan losses) and securities. This was reduced
by $16 million due to writedowns of other real estate owned and the net
difference of noninterest expense over noninterest income. Net cash provided by
investing activities was due principally to the net decreases in loans through
repayment and other real estate owned through sales, which offset an increase in
short-term investments.
 
     Other borrowings decreased $4.3 million in 1993. On July 30, 1993 the
parent company, UST Corp., paid the second annual installment of $4 million on
its 8.5% senior notes.
 
     On June 2, 1993, the Company sold 500 thousand shares of its unregistered
common stock in a private placement for cash proceeds of $3,750,000.
Substantially all of the net proceeds of that placement were used to repay
principal on the 8.5% senior notes. 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 after expenses.
Substantially all of the net proceeds continue to be held in the general funds
of the Company to be used for general corporate purposes. At December 31, 1993,
the parent company had cash and liquid investments totaling approximately $23.3
million.
 
     Separately, during the last half of 1993, USTC received approval from the
appropriate regulators to dividend $5.25 million to the Company. Of that total,
$1.7 million was contributed by the Company as capital to its Connecticut
banking subsidiary, UST Bank/Connecticut ("UST/Conn"), and $3.55 million was
contributed by the Company as capital to its lead bank, USTrust.
 
INTEREST RATE RISK
 
     Volatility in interest rates requires the Company to manage interest rate
risk. Interest rate risk arises from mismatches between the repricing or
maturity characteristics of assets and the liabilities which fund them.
Management monitors and adjusts the difference between interest-sensitive assets
and interest-sensitive liabilities ("GAP" position) within various time frames.
An institution with more assets repricing than liabilities within a given time
frame is considered asset sensitive ("positive GAP") and in time frames with
more liabilities repricing than assets it is liability sensitive ("negative
GAP"). Over a positive GAP time frame an institution will generally benefit from
rising interest rates and over a negative GAP time frame will generally benefit
from falling rates. With 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 manages its interest rate GAP primarily
by lengthening or shortening the maturity structure of the Company's portfolio
of securities.
 
     The following table summarizes the Company's GAP position at December 31,
1993. Approximately eighty percent of the loans are included in the 0-30 day
category as they reprice in response to changes in the interest rate
environment. Securities and Demand Deposits are categorized according to their
expected lives. They are evaluated in conjunction with the Company's
asset/liability management strategy and may be sold in response to changes in
interest rates, repayment risk, loan growth and similar factors. The reserve for
loan losses is included in the "Over 1 Year" category of loans. At December 31,
1993, the one-year cumulative GAP position was slightly positive at $68 million,
or approximately 3.3% of total assets.

CREDIT QUALITY AND RESERVE FOR LOAN LOSS
 
     The Company maintains a reserve for loan losses to reduce the carrying
value of its loans to an amount estimated to be collectible. Adequacy of the
reserve for loan losses is determined 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.
 
     Toward the end of the second quarter of 1993, a strategy was adopted which
recognized that many troubled credit situations will need to be handled in an
expeditious manner (including the possibility of bulk sales) 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 reserve for 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 loan losses in the second quarter. Included in that
amount was a special provision of $30 million. 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
occurring during the remainder of 1993 on these and other credits as a result of
recent events or new facts. The provision for the year ended December 31, 1993
totaled $64.3 million. Net chargeoffs in 1993 were $51.8 million compared with
$41.9 million in 1992. At December 31, 1993, the reserve for loan losses was
$62.5 million and equaled 4.74% of loans outstanding, 127% of nonaccrual loans
and 56% of total nonperforming assets.

  Net chargeoffs to average loans................        3.7%           2.7%           2.3%
</TABLE>
 
     As a result of the Company's strategy adopted in the second quarter of 1993
to resolve troubled credits more aggressively, net chargeoffs increased as noted
above, for 1993 compared with 1992. These chargeoffs and decline in other real
estate owned through sales, contributed to a $65 million or 37% decrease in
nonperforming assets in 1993.
 
     Adverse economic conditions in the future could result in further
deterioration of the Company's loan portfolio and the value of its OREO
portfolio. The effect of this would likely include increases in delinquencies,
nonperforming assets, restructured loans, and OREO writedowns which individually
or collectively could have a material negative effect on future earnings. These
factors affect the Company's income statement negatively through reduced
interest income, increased provisions for loan losses, and higher costs to
collect loans and maintain repossessed collateral.
 
     In addition to loans on nonaccrual, loans over 90 days and accruing,
troubled debt restructurings, other real estate owned and Special Mention
accruing loans 30 to 89 days past due, the Company has approximately $185
million of loans which, while current, have nonetheless been classified as
Special Mention or Substandard in the Company's internal risk rating profile.
See information following the table titled "Nonaccrual, Restructured and Past
Due Loans with Percentages of Loan Categories" on page 27 of this Form 10-K. The
risk ratings assigned to these loans were an important factor in the Company's
analysis of the adequacy of its reserve for loan losses. Proposed regulations if
implemented in their current form, however, may require the Company to reduce
significantly the level of these loans. See "Proposed New Standards on Safety
and Soundness -- Asset Quality" in Part I, Item 1 of this Form 10-K. Among the
responses available to the Company, in this event, is a further acceleration of
the Company's strategy to handle problem credits expeditiously. It is not
possible to predict the future effects on the Company's financial condition or
results of operations of actions which may be taken by the Company in response
to final regulations in this area.

     Management of the Company has identified the reduction of the aggregate
amount of non-performing and classified assets as a high priority. Management
will continue to assess its alternatives with a view to implementing the most
effective means of achieving such reduction.
 
     Decisions regarding loan loss provisions and the reserve may be influenced
by the views of the regulators having jurisdiction over the Company and its
subsidiaries.
 
CAPITAL
 
     There are three capital requirements which bank and bank holding companies
must meet. Two requirements take into consideration risk inherent in
investments, loans and other assets for both on-balance and off-balance sheet
items on a weighted basis ("risk-based assets"). 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%,
respectively. Tier 1 capital is essentially shareholders' equity, 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 Company's risk-based assets were $1.64
billion at December 31, 1993 and $1.81 billion at December 31, 1992.
 
     The third requirement is a leverage capital ratio, defined as Tier 1
capital divided by total average assets, net of intangibles. It requires a
minimum of 3% for the highest rated institutions and higher percentages for
others.

     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 Commissioner of Banks in the Commonwealth of
Massachusetts. 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. At December 31, 1993 the Tier 1 leverage capital ratios based on
average assets were 6.49% for USTrust and 23.75% for USTC.
 
     Since June 1991, 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 and November 1993 and requires UST/Conn to
maintain a 6% Tier 1 leverage capital ratio. UST/Conn Tier 1 leverage capital
ratio based on average assets at December 31, 1993 was 6.21%.
 
     At December 31, 1993, the Company had a Tier 1 leverage capital ratio of
7.06% compared to 6.21% at December 31, 1992.
 
     Additionally, per these agreements, 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 have
agreed to refrain from transferring funds in the form of dividends to the
Company without prior regulatory approval. As previously mentioned in this Form
10-K regulatory approval was obtained for dividends totaling $5.25 million from
USTC and these dividends were then contributed by the Company to its other
banking subsidiaries.

     In February 1994, the FDIC and Massachusetts commissioner terminated and
lifted the consent agreement and order with USTC. Despite the terminations of
its Regulatory Agreement, USTC has agreed to continue to request regulatory
consent prior to the payment of dividends.

COMPARISON OF 1993 WITH 1992
 
     The $64.3 million provision for loan losses coupled with a $3.1 million
increase in foreclosed asset and workout expenses when compared with those of
1992 are the primary reasons the Company reported a $20.1 million loss, or $1.31
per share, for 1993.
 
     Positive factors in 1993 included a $21 million reduction in the costs to
fund lending operations. The decreased cost outpaced the decrease in the yield
on assets. As previously mentioned, nonperforming assets were reduced from
$175.8 million at December 31, 1992 to $110.8 at December 31, 1993, a decrease
of 37%. These factors were the principal reasons that net interest income
increased in 1993.
 
     The Company's net interest income on a fully taxable equivalent basis was
$4.2 million higher in 1993 compared with 1992. This compares with a $4.6
million increase on a reporting basis. The difference is due to the decline in
tax-free income from 1992 to 1993. The Company's interest rate spread and margin
also showed considerable improvement. See "Net Interest Income Analysis" below.

Net Interest Income Analysis
 
     Substantial decreases continue to occur in the cost of the Company's
interest-bearing liabilities while average noninterest-bearing funds volume has
increased significantly since 1992. Specifically, the cost of interest-bearing
funds declined to 3.13% in 1993 compared with 3.92% for 1992. The decreased cost
has outpaced the decrease in the yield on assets. Noninterest-bearing funds
averaged $274 million for 1992 and in 1993 averaged $335 million. This is due
primarily to higher balances needed to offset costs associated with maintaining
corporate demand deposit accounts. Due to these conditions and the decline in
nonperforming assets (and the interest-related costs associated with these
assets), the interest rate spread and margin (as these terms are defined on page
22) both increased significantly during 1993. The spread in 1993 was 4.47%
compared with 3.88% for 1992. The margin was 5.03% in 1993 compared with 4.41%
in 1992. These factors caused an increase of $4.2 million in net interest income
on a taxable equivalent basis for 1993 compared with 1992.
 
     Current spreads are at historically high rates and, therefore, probably
will not continue at these levels into the future.
 
     The following table attributes changes in interest income, interest expense
and the related net interest income for the year ended December 31, 1993 when

* Fully taxable equivalent at the Federal income tax rate of 35% and includes
  applicable State taxes net of Federal benefit. The tax equivalent adjustment
  on loans was approximately $900 thousand and on nontaxable securities was
  approximately $200 thousand.

</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
continued their positive trend due to new business and appreciation of existing
clients' asset portfolios. This resulted in a $3.3 million increase in asset
management fees, partly offsetting the decrease in securities gains noted above.
Corporate services income increased $985 thousand, or 13%, in 1993. This was due
to changes in the fee system and the continued expansion of the product base.
 
     Other noninterest income decreased $466 thousand in 1993 and the following
are the more significant reasons: Leasing fee income declined $251 thousand as
the Company continued to minimize its activity in this area until taxable income
increases sufficiently. Real estate appraisal fees decreased $207 thousand 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 $350 thousand 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 $161 thousand for the quarter ended
March 31, 1992. All other miscellaneous noninterest income declined $197
thousand.
 
Noninterest Expense
 
     Noninterest expense of $97.5 million remained essentially flat in 1993
compared with 1992. Increases in foreclosed asset and workout expense amounted
to $3.1 million. Increases in writedowns to fair value minus estimated costs to
sell foreclosed real estate properties totaled $1.7 million while other
foreclosed asset and workout expenses increased $1.4 million. Writedown costs
decreased $1.6 million in the fourth quarter of 1993 compared with the same
period in 1992. However, as previously discussed under "Credit Quality and
Reserve
 
                                       19
<PAGE>   22
 
for Loan Loss," this trend may not continue. Other noninterest expense decreased
$5.9 million in 1993. In 1992, the Company added $3.8 million to a reserve for
losses arising from securitized loans. 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.
 
Income Taxes
 
     The Company had a tax benefit of $11.5 million in 1993 compared with $2.9
million in 1992. The variations in income taxes are attributable to the level
and composition of pretax income or loss.
 
     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
financial statements of this Form 10-K for a discussion of this matter.
 
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, 1993 and 1992 are
disclosed in Note 18 of the 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, 1993 was $1.93 billion and $1.89 billion, respectively. The
estimated fair value of Financial Instrument assets and liabilities of the
Company as of December 31, 1992 was $2.03 billion and $2.02 billion,
respectively. In the opinion of management, the excess in the valuation of
Financial Instrument assets and liabilities over their carrying values for 1993
and 1992 is attributed primarily to the continued decline in interest rates.

liabilities. In this table, changes attributable to both rate and volume are
allocated on a weighted basis.

* Fully taxable equivalent at the Federal corporate tax rate of 34% and includes
  applicable state taxes net of Federal tax benefit. The tax equivalent
  adjustment on loans was approximately $1.2 million and on nontaxable
  investment securities was approximately $.3 million.

</TABLE>
 
Noninterest Income
 
     Total noninterest income decreased by $1.3 million in 1992 from 1991. Asset
management fees increased $3.5 million in 1992 compared with 1991. Assets under
management increased, including appreciation of existing assets, to nearly $3
billion from approximately $2.5 billion in the previous year. Net gains on
securities were $13.5 million in 1992 compared with $10.5 million in 1991.
Corporate services income increased $391 thousand, or 6%, in 1992. This was due
to the expansion of the product base, growth in the number of clients, and
increases in fees charged. A gain on the sale of real estate during 1991
accounted for $3 million of noninterest income. Lease residual income declined
$2.6 million due to a reduction in the number of leases maturing.
 
     Other noninterest income decreased $2.7 million in 1992 and the following
are the more significant reasons. Loan servicing fees decreased $575 thousand as
a servicing contract with the Resolution Trust Corporation ended during 1992.
Leasing fee income declined $680 thousand as the Company made a decision to
minimize its activity in this area until taxable income increases sufficiently.
Other fee income which the Company generates, including fees on acceptances and
retail banking fees, declined $673 thousand as a result of a drop in the
interest rates of the acceptances and a decrease in the levels of both
acceptances and deposits.
 
Noninterest Expense
 
     Total noninterest expense in 1992 increased to $96.2 million from $89.3
million in 1991. Foreclosed asset and workout expense rose $5.8 million,
primarily due to writedowns to fair value minus estimated costs to sell
foreclosed real estate properties. These writedowns totaled $14.4 million, an
increase of $5.4 million over 1991. Increases in the amortization of core
deposit intangibles of $450 thousand, legal fees of $262 thousand, plus
additions to the reserves for litigation of $1.8 million, were partially offset
by decreases in controllable expenses such as postage and telephone expense of
$293 thousand.
 
     FDIC deposit assessment expense declined in 1992 due to the aforementioned
reduction in deposits. In 1992, the FDIC voted to restructure the assessment
system. This restructuring, which would be based on the
 
                                       21

strength of a bank and the amount of capital it has, could lead to higher
assessments in the future, if the Company fails to maintain its capital ratios.
 
     In December 1992, the Company adopted Statement of Position 92-3 ("SOP
92-3"), issued by the American Institute of Certified Public Accountants. This
statement concluded 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. For 1992, the pretax charge to income resulting from
implementation of SOP 92-3 was $750 thousand and is included in the writedown
expense of $14.4 million noted above.

(1) For the purpose of this analysis, in 1993, securities include only
    securities available-for-sale. For 1992 and 1991, securities include both
    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 pre-tax yields comparable to taxable
    loans and investments, a tax equivalent adjustment is utilized. The
    adjustment is based on a 35% Federal income tax rate (34% in 1992 and 1991)
    and includes applicable state taxes net of Federal tax benefit.
 
(3) For the purpose of this analysis, nonaccrual loans and loans held for sale
    are included in loans. There were no loans held for sale in 1993 or 1992. In
    1991, loans held for sale had an average balance of $43.6 million with
    corresponding income of $2.4 million.
 
(4) Includes $25.3 million of deposits in 1991 in a foreign office established

(5) Net interest spread is the excess of the interest rate on average earning
    assets over the interest rate on average interest-bearing liabilities.
 
(6) Net interest margin is the excess of the interest earned over interest

SECURITIES
 
     The Company has a policy of purchasing primarily securities 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 free
nature, the Company has 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 1993 includes only

(1) Certain loans for which the principal source of repayment is not real estate
     collateral dependent have been reclassified as commercial and financial for
     1992, consistent with the 1993 presentation. Information for the prior
     years is not readily available.

</TABLE>
 
     Indirect automobile installment loans represent loans purchased without
recourse from automobile dealers. Automobile loans made directly to consumers
are not a significant portion of the business and are included in the other
consumer loan category.
 
     In 1989, a total of $80 million of indirect automobile installment loans
was segregated for sale and not included in the above table. Unfavorable market
conditions in 1990 and the assumption of longer-term deposits in connection with
the Home Owners purchase and assumption transaction (See Note 2 on page 39 of
this Form 10-K) resulted in a decision by the Company not to sell those loans
and, consequently, they were reclassified to indirect automobile loans in that
year.
 
     As a result of the Home Owners transaction, 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 put back to the Resolution Trust
Corporation 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.
 
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. 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 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 the Loan Review Department management and Senior
Credit Committee whose membership includes the most senior executive officers in
the Company and the most senior lending officers in each subsidiary bank and
major lending 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 in depth monthly and actively monitors the large credit
exposures. Also in 1992 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 reports to the Company's Board. 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.
 
                                       25
<PAGE>   28
 
     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 and most nonaccrual and other troubled loans are now
largely handled by this group or in the Commercial Real Estate Department.
 
     In 1993, under the direction of new management, staffing was increased in
both the Loan Review and the Credit Risk Control Departments. Furthermore, a
number of systems changes were initiated to improve control over credit
administration, and smaller commercial loans were transferred to the Installment
Lending Department where they can be more efficiently monitored. As a result,
the commercial loan officers' workload has been reduced.

(1) The amount of interest on December 31, 1993 nonaccrual and restructured
    loans that would have been recorded had the loans been paying in accordance
    with their original terms during the year ended December 31, 1993 was
    approximately $9,743,000. The amount of interest income on these loans
    included in net income in 1993 was approximately $3,496,000.
 
(2) Information on home equity loans is available for 1990 through 1993 only.
    Prior to 1990, these loans are classified with other consumer loans.
 
(3) Other real estate owned 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. Prior to 1992, other real estate owned
    was recorded at the lower of recorded investment in the loan or fair value.
    Automobiles owned 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.
 
(4) 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.

     In addition to the amounts in the above table, accruing loans 30 to 89 days
past due and rated Special Mention in the Company's internal risk rating profile
amounted to $12 million at December 31, 1993. Also at December 31, 1993 there
were approximately $185 million of accruing commercial and real estate loans
which, while current, have nonetheless been classified as Special Mention or
Substandard an increase from approximately $130 million at the end of 1992.
There were no loans classified "Doubtful" in either year which were not
disclosed in the above table. Approximately 84 percent of these loans were in
the Substandard category. 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. The Substandard classification,
however, does not necessarily imply ultimate loss for each individual asset so
classified. Special Mention assets, 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. The Company uses the internal risk rating profile along with a
number of other factors in determining the adequacy of its reserve for loan
loss. See Credit Quality and Reserve for Loan Losses on page 14 of this Form
10-K for a further discussion.
 
ALLOCATION OF LOAN LOSS RESERVE
 
     The Company charges off loans or portions of loans when they are considered
uncollectible. Therefore, no portion of the Reserve for Loan Losses is
restricted to any loan or group of loans, and the entire Reserve is available to
absorb all probable losses inherent in the portfolio. However, for internal
analytical purposes the Company allocates its Reserve in conjunction with its
risk rating profile. Since conditions within the profile are subject to change,
the allocation presented below should not be interpreted as an indication that
chargeoffs in 1994 will occur in these amounts or proportions, or that the
allocation indicates future trends.

    mortgages and home equity lines of credit, credit cards, and check credit
    loans.

                    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, 1993 and 1992,
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, 1993. 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, 1993 and 1992, and the results of their
operations and cash flows for each of the three years in the period ended
December 31, 1993, 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, 1993
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies of UST Corp. and Subsidiaries 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 17 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 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 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 securities are
classified as held-to-maturity, available-for-sale, or trading. 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. At December 31, 1993 the
Company had no securities classified as held-to-maturity.
 
     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, 1993 and 1992,
the Company had no securities classified as trading.
 
     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. The cumulative effect of adopting SFAS 115 was
$5,749,000 before reduction for the income tax effect of $2,414,000.
 
     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
investment portfolio. 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.
 
     Prior to the adoption of FASB 115 trading account securities were valued at
market.
 
     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.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company determined 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 installment loans is
taken into 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.
 
     In May 1993, the FASB issued Statement of Financial Accounting Standards
No. 114 (SFAS No. 114), "Accounting by Creditors for Impairment of a Loan,"
which is to become effective for fiscal years beginning after December 15, 1994.
SFAS No. 114 addresses the accounting by creditors for impairment of certain
loans by requiring that the carrying value of impaired loans, as defined, be
measured based upon the present value of 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. Management is currently evaluating the effect that
this new standard will have on the Company's reported consolidated financial
position and results of operations.
 
RESERVE FOR LOAN LOSSES
 
     The reserve for 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. 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. In 1992 the pretax charge to income resulting
from implementation was $750,000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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. Loss per share computations do not include
antidilutive common stock equivalents.
 
GOODWILL
 
     Cost of purchased businesses in excess of net assets acquired includes
amount being amortized over twenty-and forty-year periods. Amortization expense
was $122,500 in 1993, 1992 and 1991.
 
RETIREMENT BENEFITS
 
     The Company's policy is to fund pension costs accrued.
 
     In December 1990, the FASB issued SFAS No. 106, "Employer's Accounting for
Post Retirement 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.
 
     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. It is not expected that this statement will have any
impact on the Company's financial position or results of operations.
 
STATEMENT OF CASH FLOWS
 
     For purpose of reporting cash flows, cash and cash equivalents include cash
on hand, amounts due from banks and interest-bearing deposits.
 
(2) HOME OWNERS PURCHASE AND ASSUMPTION
 
     On September 7, 1990, United States Trust Company ("USTC"), the Company's
principal banking subsidiary at the time, assumed approximately $2 billion in
deposits and acquired certain assets and branches located in the greater Boston
area of the former Home Owners Savings Bank F.S.B. ("Home Owners") in a
transaction with the Resolution Trust Corporation ("RTC"), an arm of the Federal
Government. The

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Company paid the RTC cash of $6.1 million, approximately the amount allocated to
core deposit intangible which is being amortized over seven years. As part of
the approval process, the Company agreed with the Board of Governors of the
Federal Reserve System and the Federal Deposit Insurance Corporation to restore
the Company's and USTC's consolidated capital ratios to the levels at which they
stood prior to the Home Owners transaction. Management developed a plan to
achieve these objectives which included putting the $513.6 million loans held
for sale back to the RTC in 1991 and continuing to reduce assets as the high
rate Home Owners certificates of deposit rolled off. This plan is complete.
 
(3) RESTRICTIONS ON CASH AND DUE FROM BANKS
 
     At December 31, 1993 and 1992, cash and due from banks included $42,072,000
and $23,659,000, respectively, to satisfy the reserve requirements of the
Federal Reserve Bank.
 
(4) SECURITIES
 
     Data presented for 1993 includes only securities available-for-sale. Data
presented for 1992 in this footnote includes both the investment portfolio,
consisting primarily of securities of states and municipalities, and other
equity securities, with an amortized cost of $8,122,000, and securities
held-for-sale, consisting primarily of U.S. Treasuries, mortgage-backed and
auto-backed securities, and corporate notes, with an amortized cost of
$468,643,000.

        The amortized cost and estimated market value of debt securities at
December 31, 1993 and 1992, 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.

(13) 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 after expenses.
 
     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 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.
 
     The Company and its two Massachusetts-based banking subsidiaries, United
States Trust Company ("USTC") and USTrust, have signed written agreements with
the FRB, FDIC and the Banking Commissioner of the Commonwealth of Massachusetts
("Massachusetts Commissioner"). In accordance with the agreements 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 have agreed to refrain from transferring funds in the form
of dividends to the Company without prior regulatory approval. In 1993, the
Company and USTC received approval from the appropriate regulators such that
USTC was allowed to transfer $5,250,000 in dividends to the Company. These
proceeds were then contributed as equity to USTrust and the Company's
Connecticut banking subsidiary, UST Bank/Connecticut ("UST/Conn"). 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'
equity, less intangible assets, divided by total average assets, less intangible
assets. 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.
 
     UST/Conn is under a Stipulation and Agreement with the Banking Commissioner
of the State of Connecticut. In accordance with the agreement, the bank, among
other matters, must maintain a Tier 1 leverage capital ratio of 6%. Based on
average total assets, at December 31, 1993, the Tier 1 leverage capital

ratio was 23.75% for United States Trust Company, 6.49% for USTrust, and 6.21%
for UST Bank/Connecticut.
 
     Additionally, the Company agreed to maintain its capital at levels
consistent with the FRB's Capital Adequacy Guidelines. At December 31, 1993,
based on period-end assets the Company's consolidated Tier 1 leverage capital
ratio was 6.96% compared with 6.21% at December 31, 1992. Based on average total
assets, this ratio was 7.06% at December 31, 1993.
 
(14) 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 do not involve more than the normal risk of collectibility. At
December 31, 1993, none of these transactions were on nonaccrual status, nor did
they involve delinquent or restructured loans. However, at December 31, 1993
loans to a Director of the Company or to his affiliated companies in the amount
of approximately $25 million 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. Subsequent to December 31, 1993, $6.4 million of these loans were
repaid. See Footnote 15 hereunder.

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.
 
POTENTIAL REGULATORY SANCTIONS
 
     Certain apparent and inadvertent violations of the insider lending
provisions (and related lending limit provisions) of Regulation O of the FRB
related to extensions of credit by USTrust to Director Francis X. Messina have
led the FDIC to require that corrective action be taken and to advise USTrust
orally that the FDIC may consider the imposition of civil money penalties with
respect to such matters. No FDIC representative has suggested to USTrust or the
Company that there was any willful or intentional misconduct on the part of
USTrust, Director Messina or USTrust's other institution-affiliated parties in
connection with these matters. See Note 14 to Consolidated Financial Statements.
 
     To address these issues, USTrust and Director Messina have undertaken a
program to reduce the aggregate balance of Mr. Messina's outstanding loans from
USTrust and to improve the collateral support for the remaining outstanding loan
balance. The elements of this program have been communicated to and reviewed by
the FDIC. In furtherance of the program since late 1993, the outstanding
principal of the aggregate loans to Director Messina and his related interests
has been reduced by more than $11 million from approximately $30 million to less
than $19 million, and such loans are now below all applicable lending limits. To
date, the Company has incurred no losses with respect to any of these loans,
although they are characterized as "Substandard" in the Company's internal risk
rating profile, and all such loans are current as to both principal and
interest.
 
     There has been no further action taken by any bank regulatory agency to
date. The FDIC has the authority to levy civil money penalties of various
amounts for violations of law or regulations, orders and written conditions and
agreements, which, depending upon the nature and severity of the violations, may
be, in situations where conduct has been egregious, as high as $1 million per
day for the period during which such violation continues. In connection with the
apparent violations described above, the FDIC has the authority to impose
penalties on any of USTrust, its Board of Directors, officers of the Bank,
Director Messina personally, "institution-affiliated parties" of USTrust or any
combination thereof.
 
     While it is not possible to predict with certainty the probability of
penalties being assessed, the person or persons upon whom any penalty would be
assessed or the amounts of any such penalties, were they to be assessed,
management of the Company believes that it is unlikely that this matter will
have a material adverse effect on its financial condition or results of
operations. Consequently, no provision in respect of penalties has been made in
the Company's Consolidated Financial Statements.
 
(16) 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 extent credit, standby
letters of credit and financial guarantees. Those instruments involve, to
varying degrees, 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.

  Commercial letters of credit.....................................       3,000            5,000
</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 $31 million and $33 million were secured by real estate at
December 31, 1993 and 1992, 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 $4 million and $13 million were
secured by real estate at December 31, 1993 and 1992, 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's securities portfolio consists largely of mortgage-backed
securities. These securities carry prepayment risk due to the fact that
prevailing interest rates could continue to 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
and Trading Account Policies.

     Cash dividends paid to the Company in 1993 by bank subsidiaries totaled
$5,250,000. There were no cash dividends paid to the Company in 1992. In 1991
the amount was $2,250,000. No cash dividends were paid to the Company by other
subsidiaries in these years.
 
(18) FINANCIAL INSTRUMENTS
 
     In December 1991, the FASB issued SFAS No. 107, "Disclosures about Fair
Value of Financial Instruments." SFAS No. 107 is effective for fiscal years
ending after December 15, 1992. SFAS 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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.
 
INVESTMENT PORTFOLIO AND SECURITIES HELD FOR SALE
 
     For marketable securities fair values are based on quoted market prices or
dealer quotes. Nonmarketable investment securities are valued at cost.
 
LOANS
 
     For certain homogenous 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.

     As shown above, the Company recorded high provisions for loan losses in the
second quarter of 1993 and third and fourth quarters of 1992. Provisions for
loan loss are recorded as necessary in order to maintain an adequate reserve for
loan loss based upon the Company's methodology for quantifying the risk inherent
in the loan portfolio.
 
     Toward the end of 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 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 loan losses in the second quarter. Included in that
amount was a special provision of $30 million. This special provision was
management's estimate of the additional losses to be incurred from the strategic
change referred to above and the continued sluggish economic climate and losses
occurring during the remainder of 1993 on these and other credits.
 
     An increase in nonaccruals in the third quarter of 1992 was a major factor
in the increased provisions for the last two quarters of 1992. In the third
quarter of 1992, the Company achieved gains on sale of securities of $10.8
million, which was a significant factor in the results for that quarter.
Noninterest income decreased after the first quarter of 1993 due primarily to a
decrease in gains on sale of securities. Noninterest expense increased or
decreased over the quarters presented due primarily to increases or decreases in
the writedowns to fair value of foreclosed real estate properties.
