                                  MAY 19, 1998
 

                                                                  April 15, 1998
 
     This Proxy Statement is furnished in connection with the solicitation of
Proxies to be used at the Annual Meeting of Stockholders of UST Corp. (the
"Company") to be held on May 19, 1998, and at any adjournments thereof, for the
purposes set forth in the foregoing Notice of Annual Meeting.
 
     The close of business on March 27, 1998 has been fixed as the record date
for the determination of stockholders entitled to notice of, and to vote at, the
Annual Meeting, and at any adjournment thereof.
 
     The financial statements for the Company for the fiscal year ended December
31, 1997, together with corresponding financial information for the previous
fiscal year, are contained in the Annual Report to UST Corp. Stockholders for
the year ended December 31, 1997 (the "Annual Report"), which includes the
Company's Annual Report to the Securities and Exchange Commission ("SEC") on
Form 10-K for the year ended December 31, 1997 (the "10-K Report"). A copy of
the Company's Annual Report and 10-K Report has been previously mailed or will
be mailed simultaneously herewith to all stockholders.
 
     Proxies in the form enclosed are solicited by the Board of Directors of the
Company. Any stockholder giving a Proxy in the enclosed form has the power to
revoke it at any time before it is exercised. A stockholder's right to revoke
his or her Proxy is not limited by, or subject to, compliance with any specified
formal procedure. Each stockholder may revoke his or her Proxy by attending the
meeting and voting in person. Proxies in such form, if received in time for
voting and not revoked, will be voted at the Annual Meeting in accordance with
the directions of the stockholders. Where a choice is not so specified, the
shares represented by a properly executed Proxy will be voted "for" the election
of the six nominees for Director positions listed therein and "for" the approval
of the Company's new Annual Incentive Plan. The enclosed Proxy confers
discretionary authority on William Schwartz, Eric R. Fischer and James K. Hunt
(or their substitutes), acting singly, to act on any other business which may
properly come before the meeting. The Board of Directors does not know of any
matters which will be brought before the meeting other than those specifically
set forth in the Notice of Annual Meeting. Should another matter, however,
properly come before the meeting, it is intended that the persons named in the
enclosed form of Proxy, or their substitutes acting thereunder, will vote on
such matter or matters in accordance with their best judgment.
 
     The Company will bear all expenses in connection with the solicitation of
Proxies, including the preparation, assembly and mailing of the Proxy Statement.
Solicitation will be initially by mail, but employees and Directors of the
Company as well as representatives of Morrow & Co., professional proxy
solicitors, may solicit Proxies by personal interview, by telephone, by
facsimile or by telecopy. Employees and Directors of the Company will not
receive additional compensation for such efforts, and Morrow & Co. is expected
to receive approximately $6,000, plus out-of-pocket expenses, for such
solicitation. The Company will also provide persons, firms, banks and
corporations holding shares in their names, or in the names of their nominees,
which in either case are beneficially owned by others, with proxy material for
transmittal to such beneficial owners and reimburse such record holders for
their reasonable expenses in so doing. Confidential voting procedures will not
be used in connection with the Annual Meeting, except that votes cast by
employees of the Company and/or its subsidiaries shall be held confidential.

     As of March 31, 1998, the Company had outstanding 29,817,577 shares of
common stock, $0.625 par value per share ("Common Stock"), each entitled to one
vote. A majority, or 14,908,789 of such shares, constitutes a quorum for the
Annual Meeting. There are no outstanding shares of Preferred Stock of the
Company.
 
                     PERSONS TO BE NOMINATED BY MANAGEMENT
                           FOR ELECTION AS DIRECTORS
                                (NOTICE ITEM 1)
 
     Section 50A of Chapter 156B of the Massachusetts General Laws provides for
a Board of Directors of such number as is fixed by the Directors, divided into
three classes as nearly equal in number as possible, serving staggered
three-year terms. The Board of Directors has fixed the number of Directors at
twenty-four (24). The Board of Directors has the power to fill vacancies and to
change the size of the Board at any time. The Board of Directors, following the
recommendation of the Nominating Committee, has recommended the following six
nominees (all of whom are currently Directors) to fill the six positions, each
of whom, if elected, will hold office for a three-year term until the 2001
Annual Meeting of Stockholders and until his or her successor is chosen and
qualified. In addition, this recommendation contemplates that two positions on
the Board of Directors expiring in 1998 will remain vacant and may be filled
later by the Board of Directors. Subject to receipt of the requisite regulatory
approvals, it is expected that upon the consummation of the proposed
acquisitions by the Company of Affiliated Community Bancorp, Inc. and Somerset
Savings Bank, some or all of these vacancies are likely to be filled by
individuals who currently serve on the respective Boards of Directors of
Affiliated Community Bancorp, Inc. and Somerset Savings Bank. Unless otherwise
specified, Proxies will be voted in favor of the six nominees' election as
Directors. Pursuant to the By-Laws of the Company, Directors will be elected by
a plurality of the votes cast at the Annual Meeting. Thus, shares for which
authority to vote for one or more nominees is withheld will have no effect on
the election of those one or more individuals.
 
     On March 17, 1998, the Board of Directors, upon the recommendation of the
Nominating Committee, established a mandatory retirement age of seventy (70)
years for members of the Board of Directors. This mandatory retirement age
policy for the Board of Directors does not affect senior officers of the Company
or USTrust, its lead banking subsidiary, who serve on the Board of Directors of
the Company. Each Director who is currently 70 or more years of age will remain
a Director until his or her term of office expires, at which time he or she will
not be eligible to be nominated for re-election. Pursuant to the new policy,
Directors who are currently less than 70 years old and who are re-elected to the
Board will retire on the date of their 70th birthday if they attain age 70
during the course of their term. One of the nominees for election at this
Meeting is Mr. Sydney L. Miller who will attain age 70 during the course of his
term and accordingly will retire on the date of his 70th birthday, December 8,
1999. Mr. Wallace M. Haselton, who has served for almost 27 years as
 
                                        2
<PAGE>   5
 
a Director of the Company, will retire as a Director when his term expires on
the date of the Annual Meeting of Stockholders, currently scheduled for May 19,
1998.

     The Company's Board of Directors has an Executive Committee, Audit

</TABLE>
 
     Instead of receiving a retainer or meeting fees, Mr. Schwartz received a
stipend of $60,000 in 1997 for his services as Chairman of the Board of
Directors. In 1997, Mr. Ridge received a stipend of $55,000 for services
performed in his capacity as Vice Chairman of USTrust, also in lieu of a
retainer or meeting fees.
 
     At the Annual Meeting of Stockholders in 1995, the 1995 Directors' Stock
Option Plan was approved by the Company's stockholders. Pursuant to that Plan,
outside Directors of the Company and USTrust received options to acquire shares
at the market price ($12.875) on the date of the meeting, May 16, 1995. Options
were granted as follows: individuals who were Directors of both the Company and
USTrust received 7,500 options; individuals who were solely Directors of the
Company received 5,100 options; individuals who were solely honorary Directors
of the Company received 4,500 options; and individuals who were solely Directors
of USTrust received 3,000 options. These options vested during 1997. In addition
to the foregoing, in May 1996, at the Annual Meeting of Stockholders, the
Company's stockholders approved the 1996 Directors' Stock Option Plan which
granted outside Directors of the Company 5,000 immediately exercisable options
at $13.438, the market price on May 21, 1996, the date of the Annual Meeting of
Stockholders.
 
     The Company also maintains a deferred compensation program which covers
Directors of the Company and Directors of any subsidiary of the Company whose
Board of Directors elects to participate. Under this program, Directors may
elect to defer all or any portion of their Directors' meeting fees and annual
stipend. Each participant is treated as a general, unsecured creditor of the
Company and has the right to receipt of his other deferred compensation upon
termination of Director status. Payments of the deferred amounts are made in
shares of Common Stock of the Company.
 
                       COMPENSATION OF EXECUTIVE OFFICERS
 
     The tables that appear below, together with the accompanying text and
footnotes, provide information on compensation and benefits for the named
Executive Officers, as determined by requirements of the Securities and Exchange
Commission (the "Named Executive Officers"). Except for the information
regarding individual stock option exercises, all the data regarding values for
stock options and grants of Restricted Common Stock are hypothetical in terms of
the amounts that an individual may or may not receive because such amounts are
contingent on continued employment with the Company and the price of the Common
Stock. All 1997 year-end values shown in these tables for outstanding Common
Stock options and Restricted Common Stock shares reflect a $27.750 price, which
was the closing price of the Common Stock for December 31, 1997, as reported in
the Nasdaq section of the Eastern Edition of The Wall Street Journal.

     As of December 31, 1997, the Company's Employee Stock Ownership Plan was
     merged into the Company's Employee Savings Plan.
 
(C) The Company entered into an Employment Agreement with Mr. Finnegan effective
    November 21, 1995 and (after a one year extension agreed to by the Company
    and Mr. Finnegan in 1996) ending January 4, 2000, and thereafter continuing
    to run year-to-year unless terminated in writing by either party upon 60-day
    notice. Pursuant to this Agreement, Mr. Finnegan receives a base salary
    (which, as of January 1, 1998, was increased from $480,000 to $520,000) and
    receives stock compensation described herein. The award was based on a price
    per share of Common Stock of $9.625 per share which reflects the closing
    price of the Company's Common Stock on December 20, 1994. The 1995
    Restricted Common Stock award of $604,688 granted to Mr. Finnegan was
    calculated at $13.4375 per share while the 150,000 options were granted at
    an exercise price of $14.4375 per share. In addition, on January 2, 1997,
    Mr. Finnegan was granted a total of 50,000 stock options, with a per share
    exercise price of $20.3125, the fair market value at the close of trading on
    January 2, 1997, as reported by The Wall Street Journal. The options became
    fully vested in 1997. As part of the Amendment to his Employment Agreement
    and to reflect the one year extension of said Agreement, Mr. Finnegan was
    granted a total of 10,800 shares of Restricted Common Stock which shall vest
    on January 2, 1999, providing him with Restricted Common Stock for the
    additional year of his contract on a basis consistent with the prior years
    of his contract period. See "Employment Agreements."
 
(D) As of January 1, 1995, the Company and USTC entered into an Employment
    Agreement with Mr. Colasacco. This Employment Agreement contains information
    related to, among other matters, Mr. Colasacco's incentive compensation. Mr.
    Colasacco's Employment Agreement is described under "Employment Agreements."
 
(E) Mr. Hunt entered into a restated and amended two-year Employment Agreement
    dated February 1, 1996 and thereafter continuing to run year-to-year unless
    terminated in writing by either party upon 60-day notice. See "Employment
    Agreements."
 
(F) Mr. McAlear entered into a two-year Employment Agreement dated February 1,
    1996 and thereafter continuing to run year-to-year unless terminated in
    writing by either party upon 60-day notice. See "Employment Agreements."
 
(G) Ms. Stevens entered into a two-year Employment Agreement dated February 1,
    1996 and thereafter continuing to run year-to-year unless terminated in
    writing by either party upon 60-day notice. See "Employment Agreements."
 
                            STOCK-BASED COMPENSATION
 
     The Stock Compensation Plan originally adopted in 1992, as amended to date,
provides for granting of Incentive Stock Options, Nonqualified Stock Options and
Restricted Common Stock Awards or a combina-
                                        9
<PAGE>   12
 
tion of the foregoing as a means by which the Company seeks to attract and
retain highly qualified Officers and attract and encourage able persons to enter
into and remain in the Company's and its subsidiaries' employ. The Plan is
designed to encourage key employees of the Company and its subsidiaries to
acquire and maintain stock ownership, thereby strengthening their commitment to
the welfare of the Company and promoting the identity of interests between
stockholders and key employees.
 
     The following table provides details regarding stock options granted to the
Named Executive Officers in 1997 under the Stock Compensation Plan. In addition,
in accordance with SEC rules, this table shows hypothetical gains on a pre-tax
basis or "option spreads" that would exist for the respective options granted in
1997 for the Named Executive Officers. These gains are based on assumed rates of

     To the extent that benefits cannot be provided under the Pension Plan or
certain other retirement plans of the Company because of the limitations imposed
by Sections 415 and 401(a)(17) of the Internal Revenue Code on the amount of
such benefits payable, any balance of benefits otherwise payable under such
plans will be provided by the Company to eligible Officers pursuant to a
Supplemental Retirement Benefits Plan adopted by the Board of Directors. As of
December 31, 1997, all individuals named in the Summary Compensation Table were
covered by the Supplemental Retirement Benefits Plan. In addition, as of January
1, 1997, all individuals named in the Summary Compensation Table except Mr.
Colasacco were covered by the Executive Policy Committee Supplemental Plan. This
plan is a supplemental retirement plan which provides a maximum benefit equal to
50% of five year average compensation. For purposes of this plan, compensation
includes bonus.
 
                         COMPENSATION COMMITTEE REPORT
 
COMPENSATION PHILOSOPHY
 
     This Report reflects the Company's compensation philosophy and resulting
actions taken by the Company for 1997, as shown in the various compensation
tables above. The Compensation Committee either approves or recommends to the
Board of Directors salary and bonus amounts and stock award levels for Executive
Officers of the Company and its affiliates. Directors who were also Executive
Officers did not participate in votes concerning their own remuneration or plans
under which they were eligible to receive any benefits.
 
     Compensation of Executive Officers of the Company has been designed
generally to: (i) compensate Executive Officers based upon corporate, business
unit and individual performance; (ii) motivate Executive
 
                                       11
<PAGE>   14
 
Officers to achieve strategic business initiatives and reward them for their
achievement; (iii) provide salary arrangements which are comparable (and in the
aggregate at approximately the 60th percentile when compared to those of the
Company's peer group competitors) as described below under "Salary"; and (iv)
align the interests of executives with the long-term interests of stockholders
through award opportunities that can result in the ownership of Common Stock.
The Committee does not at present, however, have any specific target level of
Common Stock ownership.
 
     In 1997, executive compensation was composed of base salary, discretionary
annual incentive awards, long-term incentive opportunities in the form of stock
options and Restricted Common Stock, and benefits typically offered to
executives by the Company's peer group competitors. Generally, (except as noted
below with respect to the key executives of USTC's Asset Management Division) as
an executive's level of responsibility increases, a greater portion of potential
total compensation tends to be based upon performance incentives and less on
salary and employee benefits, often causing greater variability in the
individual's absolute compensation level from year to year. Generally, the
higher one rises in the organization, the greater the mix of compensation shifts
to reliance on the Common Stock through stock-based awards. Specific
compensation and award levels are determined by the Compensation Committee,
using its discretion and considering both objective and subjective criteria.
 
     In 1996, the Compensation Committee adopted a written "UST Corp. Executive
Compensation Philosophy" (the "Compensation Philosophy"). The Compensation
Philosophy utilizes comparable peer company data surveys conducted by Watson
Wyatt Worldwide, the Company's independent employee benefit and compensation
consultants, and calls for procedures under which: (i) base salary shall be set
so that the targeted positioning is the 60th percentile for each position, based
on asset size or such other scope criteria. Actual base salary for an individual
relative to the target pay shall be determined based on the individual's unique
background, experiences, personal skills and abilities as well as the business
challenges facing the Company which require the use of such attributes or
skills; (ii) annual incentive targets shall be set at levels which approximate
the 60th percentile of total compensation, so as to drive and reward consistent
improvement in performance. The same surveys and peer company data used to
establish salary ranges are to be used to calibrate incentive earning potential.
Performance goals may be set at levels which approximate the 75th percentile of
total compensation; and (iii) the annualized value of long-term incentive
targets shall be set at levels which approximate the 60th percentile of the
competitive total compensation, so as to drive and reward consistent improvement
in performance and shareholder value. Peer company data will be used to
calibrate long-term incentive earning potential. Performance goals may be set at
levels which approximate the 75th percentile of competitive total direct
compensation values.
 
     Mr. Colasacco and the other key executives of USTC's Asset Management
Division are compensated primarily through a cash-based, revenue sharing
arrangement which is generally based upon gross revenues earned by the Division.
See "Employment Agreements" below with respect to Mr. Colasacco's Employment
Agreement.
 
     Over the five years since Mr. Finnegan joined the Company in April, 1993,
he has selected a senior management team composed of newly-hired and previously
employed members of the Executive Policy Committee to direct the activities of
the Company. See "Executive Officers of the Company" below for a full listing of
the current Executive Policy Committee members' names, principal
responsibilities and backgrounds. The Compensation Committee has granted
substantial stock compensation to Mr. Finnegan and the other members of the
Executive Policy Committee of the Company in order to align more closely the
economic interests of these Officers with those of the Company's stockholders.
 
GENERAL BACKGROUND
 
     As indicated in the Five-Year Stockholder Return comparison, which is found
at the end of the discussion of Compensation of Executive Officers, the
five-year performance (including reinvestment of dividends) of the Company's
Common Stock has lagged behind the Keefe, Bruyette & Woods ("KBW") New England
Bank Index. Over much of the same period, the Company's Common Stock has
out-performed the Standard & Poor's 500 Index.
 
                                       12
<PAGE>   15
 
     The following is a discussion of the Compensation Committee's bases for Mr.
Finnegan's compensation reported for 1997, and its general policies with respect
to the other Named Executive Officers in the Summary Compensation Table. Mr.
Finnegan served as Chief Executive Officer throughout 1997.
 
SALARY
 
     The Employment Agreement between Mr. Finnegan and the Company dated as of
November 21, 1995 was amended as of January 2, 1997 (the "Amendment"). The
Compensation Committee increased Mr. Finnegan's base salary from $480,000 to
$520,000 effective January 1, 1998. Based upon salary surveys of approximately
35 similarly-sized regional and national bank holding companies provided to the
Compensation Committee, and advice provided by Watson Wyatt Worldwide, this base
salary was and continues to be competitive with the base salaries of Chief
Executive Officers of the banks and bank holding companies surveyed.
 
1997 CASH BONUS AWARDS
 
     Mr. Finnegan received a $380,000 cash bonus in late 1997 and early 1998 to
reflect his performance during 1997 (which is reflected in the Summary
Compensation Table), based upon a subjective determination of the Compensation
Committee, considering in particular the excellent financial performance of the
Company in 1997, the increase in the share price of the Company's Common Stock
and the significant increase in the asset size and the complexity of the Company
as a result of acquisitions and the integration of a significant branch purchase
transaction completed at the end of 1996. Under the matching contribution
feature of UST Corp.'s Employee Savings Plan, Mr. Finnegan received an aggregate
contribution of $4,800 for 1997. Mr. Finnegan also received an aggregate of
$3,775 in 1997 as a result of forfeitures.
 
1997 STOCK AWARDS
 
     The Company's Stock Compensation Plan, approved by stockholders in 1992,
permits the granting of several different types of stock-based awards. The
Company's 1989 Restricted Common Stock Bonus Award Program permits the granting
of awards of Restricted Common Stock. Prior to 1995, stock options were granted
to certain Executive Officers and key employees under the 1992 Stock
Compensation Plan and all awards of Restricted Common Stock were made under the
1989 Restricted Common Stock Bonus Award Program. Mr. Finnegan was granted an
aggregate of 150,000 options exercisable within five years and 60 days to
acquire Common Stock and 60,000 shares of Restricted Common Stock during 1993.
In January 1994, the Company also granted Mr. Finnegan options for 200,000
shares of Common Stock. In 1995, the Company granted Mr. Finnegan an additional
5,195 shares of Restricted Common Stock under the 1989 Bonus Award Program and a
$150,000 cash bonus. Also in 1995, Mr. Finnegan was granted an aggregate of
150,000 options to acquire Common Stock and 45,000 shares of Restricted Common
Stock under the 1992 Stock Compensation Plan. On January 2, 1997 Mr. Finnegan
was granted a total of 50,000 stock options, priced at $20.3125, the fair market
value at the close of trading on January 2, 1997, as reported by The Wall Street
Journal. The options vested in 1997. As part of the Amendment and to reflect the
one year extension of his employment agreement, Mr. Finnegan also received a
10,800 share Restricted Common Stock bonus in early 1997 which provides him with
Restricted Common Stock for the additional year of his contract on a basis
consistent with the prior years of his contract period. Under the Company's
Employee Stock Ownership Plan, Mr. Finnegan received a contribution of $1,313
for 1997. Mr. Finnegan also received an aggregate of $1,770 in 1997 as a result
of forfeitures. See "Employment Agreements."
 
LIMITATION ON DEDUCTIBILITY OF EXECUTIVE COMPENSATION
 
     The Internal Revenue Code was amended in 1993 to disallow deductions on
annual compensation in excess of $1,000,000 for certain executives of public
companies, beginning in 1994. The Compensation Committee accordingly amended the
Stock Compensation Plan, imposing a per-employee limit on annual grants, which
was approved by the Company's stockholders at the 1994 Annual Meeting. The
Compensation Committee has monitored the impact of this law over the past
several years and has taken into consideration both the benefits of favorable
tax treatment for the Company, and the necessity for the Compensation
                                       13
<PAGE>   16
 
Committee to have the discretion to take appropriate steps to further its
executive compensation philosophy and honor existing contractual obligations. As
a result of the foregoing, the Compensation Committee recommended to the Board
of Directors that the Company adopt the new Annual Incentive Plan which
addresses the foregoing tax considerations. The Board of Directors approved the
new Annual Incentive Plan and has recommended that the stockholders approve the
new Annual Incentive Plan at the Annual Meeting scheduled to be held on May 19,
1998. See Notice Item 2 for further discussion of the new Annual Incentive Plan
and Exhibit A attached hereto for the text of the Annual Incentive Plan.
 
     This Report was submitted by the Compensation Committee which is comprised
of the following Directors, none of whom are full-time employees of the Company
or any of its subsidiaries:
 
         Donald C. Dolben, Chairman
         Paul D. Slater, Vice Chairman
         Robert L. Culver
         Francis X. Messina
         Gordon M. Weiner
 
          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During 1997, the following persons served for a portion or all of the year
on the Compensation Committee: Robert L. Culver, Donald C. Dolben, Wallace M.
Haselton, Francis X. Messina, Paul D. Slater and Gordon M. Weiner.
 
     Officers and Directors of the Company, and their associates, are customers
of the Company and its subsidiaries and, as such, may have obtained loans and
loan commitments in excess of $60,000. All such loans and loan commitments
outstanding since the beginning of the last fiscal year were made in the
ordinary course of business by the Company's banking subsidiaries and on
substantially the same terms, including interest rates and collateral, as those
prevailing at the time for comparable transactions with other persons and did
not involve more than the normal risk of collectability or present other
unfavorable terms.
 
     The members of the Compensation Committee, and their respective associates,
may have had an interest in certain transactions involving the Company or its
subsidiaries during 1997. In addition to loan transactions and other customer
transactions, during the past fiscal year the Company and its subsidiaries have
used products or services of, and have had other transactions with, various
organizations with which Officers and Directors of the Company are affiliated.
The amounts involved have in no case been material in relation to the business
of the Company and its subsidiaries and it is believed that they have not been
material in relation to the business of such other organizations or to the
individuals concerned. It is expected that in the future the Company and its
subsidiaries will continue to have transactions similar to those described in
this paragraph.
 
                    FIVE-YEAR STOCKHOLDER RETURN COMPARISON
 
     The following table compares the total return on the Company's Common Stock
over the last five years to the Keefe, Bruyette & Woods ("KBW") New England Bank
Index and the Standard & Poor's 500 Index ("S&P 500"). The KBW New England Bank
Index is comprised of approximately 18 commercial and savings banks located
within the five New England states and ranging in asset size from approximately
$400 million to $3 billion. The Company has decided to include comparisons to
this index, which only first became available in 1994, because it provides a
closer comparison to the Company as it is entirely an index of smaller New
England banks and bank holding companies with similar geographical, size and
market characteristics. Most banks that use the KBW New England Bank Index also
compare themselves to the S&P 500. Total return values for these indices were
calculated based on cumulative total return values, assuming reinvestment of
dividends.

                             EMPLOYMENT AGREEMENTS
 
     Mr. Finnegan joined the Company in 1993 as President and Chief Executive
Officer of the Company. He has an Employment Agreement with the Company dated as
of November 21, 1995 and amended on January 2, 1997. The Employment Agreement,
as amended, was effective November 21, 1995 and ends on January 4, 2000, and
provides that Mr. Finnegan will serve as President and Chief Executive Officer
of the Company. Mr. Finnegan is paid a base salary of $520,000 per annum, is
eligible for discretionary bonuses and is entitled to those fringe benefits made
available to other senior executives. Mr. Finnegan has received under the
Employment Agreement, as amended, an aggregate of 55,800 shares of Restricted
Common Stock which vest over a three-year period and an aggregate of 200,000
options to acquire the Company's Common Stock at the exercise prices shown in
the tables above. In addition, Mr. Finnegan received under his prior Employment
Agreement, as amended, 60,000 shares of Restricted Common Stock, all of which
have vested and an aggregate of 350,000 options to acquire the Company's Common
Stock. Mr. Finnegan has agreed to a non-competition provision in the Agreement.
In the event of a Change-in-Control (as defined in Mr. Finnegan's Employment
Agreement) of the Company during the term of the Employment Agreement, Mr.
Finnegan may elect: (i) to terminate this Agreement and receive a payment equal
to 2.99 times his "base amount" as defined under Section 280G(b)(3) of the
Internal Revenue Code; or (ii) should his termination be involuntary, to sue for
damages. Should Mr. Finnegan have any unvested shares of Restricted Common Stock
or stock options at the time of a Change-in-Control, vesting of all such shares
shall be accelerated and he will have the right if other employees can have
their options or Restricted Common Stock cashed out, to likewise cash out on the
same basis and at the same time as such other employees. As an example, assuming
a hypothetical Change-in-Control had occurred on March 1, 1998, Mr. Finnegan
would have received, under option (i) above, $2,435,100; however, in any case,
the total amounts payable to Mr. Finnegan upon a Change-in-Control shall be
limited to the maximum amount that is deductible to the Company under Section
280G of the Internal Revenue Code.
 
     Mr. Colasacco, Executive Vice President of the Company and Chairman and
President of USTC, has entered into an Employment Agreement with USTC and joined
in by the Company, dated as of January 1, 1995. The Employment Agreement had a
two and one-half year original term and (unless terminated by Mr. Colasacco by
giving the Company and USTC six months prior notice) successive six month
renewal terms thereafter. In the event, however, that a change in control of
USTC or the Company or other Triggering Event (as defined in the Employment
Agreement) occurs during a renewal term, a new, approximately three-year term
will be triggered and Mr. Colasacco will receive in exchange for an extension of
his employment period and a related noncompetition agreement, the portion
allocated to him of a Formula Payment, as defined in the Employment Agreement,
based upon USTC's Asset Management Division's (the "Division") gross revenues
during the four consecutive calendar quarters preceding the Triggering Event.
During the term of his Employment Agreement, unlike other Executive Officers of
the Company, Mr. Colasacco has not been granted any options to acquire Common
Stock of the Company and Mr. Colasacco's part of the Formula Payment is intended
to substitute for remuneration through the grant of stock options.
 
     Mr. Colasacco's current base salary is $225,375 per annum. Under the
Employment Agreement, and similar agreements with the other, currently four, key
managers of the Division (the "Key Division Managers") the Key Division Managers
receive an aggregate share of the Division's net revenues. Each year, the
Division's gross revenues are compared against a predetermined target, which was
negotiated at the time of the commencement of the Employment Agreement term and
which is adjusted annually for inflation. The aggregate share of the Division's
revenues is a product of approximately 60% of this target. Such share of the
Division's revenue is adjusted for the actual annual revenue performance of the
Division relative to the target. The operating expenses of the Division are
deducted from the aggregate share of the Division's revenues to determine the
amount of incentive balance available to the Key Division Managers. Under the
Employment Agreement, the Key Division Managers determine, as a group, the share
of revenues to be currently allocated to individual managers, including Mr.
Colasacco, after the adjustments due to performance and operating expenses. In
1998, Mr. Colasacco received $600,000 as a result of this revenue sharing
agreement, largely related to his performance in 1997. Under this revenue
sharing arrangement, Mr. Colasacco may also become entitled to receive
substantial, additional amounts from the unpaid incentive balances which would
be
 
                                       16
<PAGE>   19
 
allocated among the Key Division Managers. For Mr. Colasacco, the additional
amount allocated from unpaid incentive balances which existed at December 31,
1997 could be in excess of $1 million. The Key Division Managers, subject to
generation of adequate revenues, are also empowered to change Mr. Colasacco's
base annual salary.
 
     Under the Employment Agreement, in the event there is a change in control
of USTC or the Company or other Triggering Event (as defined in the Employment
Agreement), Mr. Colasacco would be entitled to payment equal to the percentage
currently allocated to him under the Division's agreement among the Key Division
Managers multiplied by the product of 3.33 times the Division's after tax
revenues for the previous four consecutive calendar quarters. As an example,
assuming a hypothetical change-in-control had occurred on March 1, 1998, Mr.
Colasacco would have received approximately $2.7 million ($3.35 million
multiplied by 3.33 and further multiplied by 25%, the share currently allocated
to Mr. Colasacco under the Division's agreement among the Key Division
Managers). As discussed above, Mr. Colasacco may also become entitled to receive
additional amounts from the unpaid incentive balances which existed at December
31, 1997.
 
     Mr. Hunt, Executive Vice President, Treasurer and Chief Financial Officer
of the Company, entered into a restated and amended two-year Employment
Agreement with the Company, dated February 1, 1996, which thereafter continues
to run year-to-year unless terminated in writing by either party upon 60-day
notice. Under the terms of the Employment Agreement, Mr. Hunt is paid a base
salary of $250,000 per annum, is eligible for discretionary bonuses and has been
entitled to fringe benefits available to senior executives. Through December 31,
1997, Mr. Hunt has also received an aggregate of 26,100 shares of Restricted
Common Stock and aggregate options to purchase 72,500 shares of the Company's
Common Stock at an average purchase price of $13.41 per share. On January 13,
1998, Mr. Hunt was granted a total of 15,000 stock options, priced at $24.6875,
the fair market value at the close of trading on January 13, 1998. On January
13, 1998, Mr. Hunt was also granted 4,500 shares of Restricted Common Stock,
1,500 shares of which constituted part of the payment of his annual bonus award
for 1997. Under the terms of the Employment Agreement, Mr. Hunt has also agreed
to certain non-solicitation and confidentiality provisions. In addition, under
the Employment Agreement, as amended on December 17, 1996, in the event there is
a Change-in-Control of the Company (as defined in the Employment Agreement) and
Mr. Hunt is not offered continued employment in a similar position with the
successor entity, Mr. Hunt will be entitled to a severance payment equal to two
times the sum of (i) his then current annual base salary for the then most
recent year plus (ii) the bonus which Mr. Hunt earned for performance during the
previous calendar year. As an example, assuming a hypothetical Change-in-Control
had occurred on March 1, 1998, and Mr. Hunt was not offered continued employment
in a similar position with the successor entity, Mr. Hunt would have received
$734,100 ($250,000 base salary plus $117,000 bonus times 2); however, in any
case, the total amounts payable to Mr. Hunt upon a Change-in-Control shall be
limited to the maximum amount that is deductible to the Company under Section
280G of the Internal Revenue Code.
 
     Mr. McAlear, Executive Vice President/Banking Operations and Acquisition
Integration of the Company and Vice Chairman of USTrust, entered into a two-year
Employment Agreement with the Company, dated February 1, 1996, which thereafter
continues year-to-year unless terminated in writing by either party upon 60-day
notice. Under the terms of the Employment Agreement, Mr. McAlear is paid a base
salary of $230,000 per annum subject to discretionary increases, has been
eligible for discretionary bonuses and is entitled to fringe benefits available
to senior executives. Through December 31, 1997, Mr. McAlear has also received
an aggregate of 9,000 shares of Restricted Common Stock and aggregate options to
purchase 88,550 shares of the Company's Common Stock at an average purchase
price of $11.86 per share. On January 13, 1998, Mr. McAlear was granted a total
of 10,000 stock options, priced at $24.6875, the fair market value at the close
of trading on January 13, 1998. On January 13, 1998, Mr. McAlear was also
granted 3,000 shares of Restricted Common Stock, 1,000 shares of which
constituted part of the payment of his annual bonus award for 1997. Under the
terms of the Employment Agreement, Mr. McAlear has also agreed to certain non-
solicitation and confidentiality provisions. In addition, under the Employment
Agreement, as amended on December 17, 1996, in the event there is a
Change-in-Control of the Company (as defined in the Employment Agreement) and
Mr. McAlear is not offered continued employment in a similar position with the
successor entity, Mr. McAlear will be entitled to a severance payment equal to
two times the sum of (i) his then current
 
                                       17
<PAGE>   20
 
annual base salary for the then most recent year plus (ii) an amount equal to
the bonus which Mr. McAlear earned for performance during the previous calendar
year. As an example, assuming a Change-in-Control had occurred on March 1, 1998
and Mr. McAlear was not offered continued employment in a similar position with
the successor entity, Mr. McAlear would have received $589,100 ($230,000 base
salary plus $64,700 bonus times 2); however, in any case, the total amounts
payable to Mr. McAlear upon a Change-in-Control shall be limited to the maximum
amount that is deductible to the Company under Section 280G of the Internal
Revenue Code.
 
     Ms. Stevens, Executive Vice President/Credit and Controlled Loans and
Senior Lending Officer of the Company and Vice Chairman of USTrust, entered into

                                (NOTICE ITEM 2)
 
     The Company's Annual Incentive Plan (the "Incentive Plan") was adopted by
the Board of Directors of the Company on March 17, 1998, subject to approval by
the stockholders of the Company. The Incentive Plan is intended to advance the
Company's interest by enhancing its ability to attract and retain key executives
of the Company through the grant of performance-based incentive awards.
 
     Under Section 162(m) of the Internal Revenue Code (the "Code"), the
deductibility of compensation to any of a corporation's "covered employees"
(generally, the Chief Executive Officer and the other four top officers by pay)
is limited to $1,000,000 in any year. Certain performance-based compensation
under shareholder approved plans may qualify for an exception to this deduction
limitation. The Incentive Plan permits the grant of awards to eligible
executives who are or are likely to be "covered employees" as so defined and
whose award compensation (if not exempted) would likely be subject in whole or
in part to the deduction limitation ("Section 162(m) officers"), as well as
awards to other key employees. Awards under the plan to Section 162(m) officers
are intended to qualify for the performance-based exemption under Section 162(m)
of the Code.
 
     The Incentive Plan contemplates that amounts earned under awards may be
paid in the form of cash or Restricted Common Stock. Any shares of Restricted
Common Stock delivered in satisfaction of amounts earned under an Incentive Plan
award would be issued under, and would be subject to the additional terms of,
the Company's Stock Compensation Plan.
 
     Stockholders of the Company are requested to approve the Incentive Plan at
the Annual Meeting. Any awards made under the Incentive Plan prior to the Annual
Meeting will be subject to such approval. The following summary of the Incentive
Plan is qualified in its entirety by the full text of the Incentive Plan that
appears as Exhibit A attached to this Proxy Statement.
 
ADMINISTRATION
 
     The Incentive Plan is administered by the Compensation Committee. Except
for matters pertaining to awards to Section 162(m) officers or matters requiring
action by the Compensation Committee under the
 
                                       21
<PAGE>   24
 
Stock Compensation Plan, the Compensation Committee may delegate its functions
under the Incentive Plan to the Chief Executive Officer of the Company.
 
ELIGIBILITY
 
     Participation in the Incentive Plan is limited to those executives and
other key employees of the Company who are from time to time selected by the
Compensation Committee. Eligible persons selected to participate in the
Incentive Plan for a particular year may, but need not, be selected for
participation in any subsequent year.
 
GRANT OF AWARDS; ESTABLISHMENT OF PERFORMANCE GOALS
 
     Each year the Compensation Committee may grant awards to those eligible
employees who have been selected to participate in the Incentive Plan for the
year. Each award will specify the performance goals (including, if the
Compensation Committee so determines, minimum, target, maximum or other measures
of achievement) that must be met in order for payment or specified levels of
payment to be made under the award. Except in the case of awards to Section
162(m) officers, award payments may be based in whole or in part on subjective
performance measures. The maximum payment that may be made to any participant
under the Incentive Plan for any year is $1,750,000. If any portion of an award
is paid in the form of shares of Common Stock, the limitation described in the
preceding sentence will be applied by valuing such shares at their closing price
on the trading date immediately preceding the date payments under the award are
made.
 
     Special additional rules apply in the case of awards to Section 162(m)
officers. In general, payments under an award to a Section 162(m) officer must
be contingent on satisfaction of one or more qualifying performance goals that
have been preestablished by the Compensation Committee not later than 90 days
after the commencement of the fiscal year to which the award relates (although
the Compensation Committee may retain and exercise the discretion to lower or
eliminate payments under an award, including on the basis of subjective
performances considerations, even if the preestablished performance goals have
been satisfied), and no payment will be made until the Compensation Committee
certifies to the extent required under Section 162(m) of the Code that the
preestablished goals have been met. For purposes of the Incentive Plan, a
qualifying performance goal is one that states an objective performance formula
or standard based on any one or more of the following determined by reference to
the Company on a consolidated basis in accordance with generally accepted
accounting principles consistently applied: (i) adjusted net income before
securities transactions and before any extraordinary, unusual or non-recurring
items of gain or loss that are identified and quantified separately in the
audited financial statements, net of tax effect and after preferred dividends;
(ii) return on average assets, determined by dividing adjusted net income (as
defined) by average total assets for the year; (iii) return on average equity,
determined by dividing adjusted net income (as defined) by average adjusted
stockholders' investment for the year excluding any adjustment for SFAS No. 115;
(iv) earnings per share, determined by dividing adjusted net income (as defined)
by the weighted average number of fully diluted shares during the measurement
period; (v) asset quality, defined as the ratio of substandard and nonperforming
assets to the sum of total loans and the balance in the reserve for possible
loan losses; (vi) efficiency ratio, defined as noninterest expense, excluding
expenses related to other real estate owned and any extraordinary, unusual or
non-recurring items, divided by the total revenue from net interest income plus
noninterest income, excluding the effect of gains and losses from the sale of
assets and any extraordinary or nonrecurring items of gain or loss that are
identified and quantified separately in the audited financial statements; and
(vii) asset growth, defined as the difference between average total assets for
the year and the prior year divided by average assets as reported for the prior
year.
 
PAYMENT OF AWARDS
 
     In general, amounts (if any) payable under an award will be determined and
paid only after the close of the fiscal year to which the award relates (and, in
the case of awards to Section 162(m) officers, only after certification by the
Compensation Committee that the performance goals to which the award was subject
have been met), and a participant must be employed by the Company on the date of
payment in order to receive the payment. However, the Incentive Plan provides
for possible earlier payment in certain circumstances. If a
                                       22
<PAGE>   25
 
participant suffers a termination of employment by reason of death or disability
(as determined under the Incentive Plan), the Company will pay to the
participant or, in the case of death, to the participant's designated
beneficiary or estate a prorated portion of the estimated benefit that in the
Compensation Committee's judgment would have been earned had the participant
continued in employment. If a change in control of the Company occurs, the
Company will promptly pay to each participant for the year in which the change
in control occurs the greater of his or her target award for the year (based on
the participant's base salary rate in effect at time of payment or the rate in
effect immediately prior to the change in control, if higher) or, if the change
in control occurs after at least six months of the fiscal year have elapsed, the
payment the participant would have received under his or her award (assuming no
reduction for factors other than qualified performance factors as described
above) assuming fiscal year performance equal to the annualized equivalent of
performance measured through the most recent practicable measuring date
coinciding with or preceding the date of the change in control. If award
payments for the preceding fiscal year have not yet been determined or paid, the
Company will also pay those award payments based on performance for the year
(and assuming no reduction for subjective performance factors).
 
AMENDMENT AND TERMINATION
 
     The Incentive Plan has no fixed expiration date. Under the regulations
under Section 162(m) of the Code, however, if the Incentive Plan is approved at
the Annual Meeting, the continued exemption of awards under the Incentive Plan
would require that the material terms of the performance goals applicable to
Section 162(m) officers be again disclosed to and approved by the shareholders
of the Company not later than the first shareholder meeting occurring in 2003.
The Board of Directors and the Compensation Committee reserve the right to amend
or terminate the Incentive Plan at any time, including as to awards already
granted but not paid. No amendment or termination would affect a participant's
rights to any Restricted Common Stock that had been issued under the Stock
Compensation Plan except to the extent, if any, provided in that plan.
 
RECOMMENDATION OF YOUR BOARD OF DIRECTORS TO VOTE "FOR" THIS PROPOSAL
 
     The Board of Directors believes that the adoption of the Annual Incentive
Plan will promote the interests of the Company and the stockholders and help the
Company and its subsidiaries to attract and retain qualified senior executives.
Accordingly, the Board of Directors has approved the adoption of the Annual
Incentive Plan and recommends that the stockholders vote "for" the proposal to
adopt the Annual Incentive Plan. Proxies solicited by the Board of Directors
will be so voted unless stockholders specify otherwise.
 
     To approve the Annual Incentive Plan, the vote holders of a majority of the
shares present or represented and entitled to vote on the proposal at the
meeting is required. An abstention will have the effect of a vote against the
proposal, while a broker non-vote (i.e., shares held by brokers or nominees as
to which (i) instructions have not been received from the beneficial owners and
(ii) the broker or nominee does not have the discretionary authority to vote on
a particular matter) will have no effect on the outcome.
 
                      ACTION TO BE TAKEN -- OTHER BUSINESS
                                (NOTICE ITEM 3)
 
     As of the date of this Proxy Statement, the Board of Directors does not
intend to present at the Meeting any business other than the two specific items
listed in the notice, and it has not been informed of any business intended to
be presented by others. Should any other matters, however, properly come before
the meeting, the persons named in the enclosed Proxy will take action, and vote
Proxies, in accordance with their judgment on such matters.
 
     Action may be taken on the business to be transacted at the meeting on the
date specified in the Notice of Annual Meeting or on any date or dates to which
such meeting may be adjourned.

requires the Company's Executive Officers and Directors to file reports of
ownership and changes in ownership with the Securities and Exchange Commission.
Executive Officers and Directors are required by SEC regulations to furnish the
Company with copies of all Section 16(a) forms they file. Based solely upon its
review of the copies of such forms and certain certifications received from the
Directors and Executive Officers, the Company believes that, during 1997, all
such filing requirements applicable to its Executive Officers and Directors were
complied with by such individuals.
 
                             STOCKHOLDER PROPOSALS

        Code all determined by the Committee.
 
     -  "Stock Plan": The Corporation's Stock Compensation Plan.
 
     3.  Administration of the Plan.  The Plan shall be administered by the
Committee, which shall have the authority in its discretion to determine
eligibility for and grant Awards, to determine the terms and conditions of any
Award, to prescribe such forms and documents as it deems appropriate in
connection with the administration of the Plan, to construe the terms of the
Plan and resolve all questions arising under the Plan, to determine and certify
as to whether the conditions for payment under any Award have been met, and
generally to do all such things as it deems necessary or appropriate to
administer the Plan. The Committee may delegate to the Chief Executive Officer
the authority to exercise the authority described in the preceding sentence with
respect to Awards to Participants other than Section 162(m) officers, and may
delegate ministerial responsibilities to such employees of the Corporation as it
deems appropriate. If the Committee so delegates its authority to the Chief
Executive Officer, references herein to the Committee (other than in Section 15)
shall be deemed to include the Chief Executive Officer to the extent of such
delegation. No determination by the Chief Executive Officer under the Plan shall
affect the grant, determination, or construction of (or the determination or
payment of any amounts under) any Award involving a Section 162(m) officer.
 
     4.  Participation.  The Committee shall select which Eligible Employees are
to participate in the Plan for any Fiscal Year. The fact that an Eligible
Employee has been selected to participate in the Plan for a Fiscal Year shall
not entitle such Eligible Employee to participate in the Plan, or if a
Participant to receive a comparable Award, for any subsequent Fiscal Year.
 
     5.  Grants of Awards.  The Committee shall grant Awards under the Plan for
each Fiscal Year at such time or times as it deems appropriate; provided, that
in the case of a Section 162(m) officer, any Award for a Fiscal Year shall be
made not later than 90 days after the commencement of the Fiscal Year. In
connection with each Award (and, in the case of Awards to Section 162(m)
officers, not later than 90 days after the commencement of the Fiscal Year), the
Committee shall establish the performance goals required to be met, in whole or
in part, in order for an Award Payment to be made with respect to the Award and
the target, maximum or other amount or amounts, expressed as a percentage of
base salary, that may be paid if such performance goals are so met. In the case
of Awards to Section 162(m) officers, such performance goals shall be
susceptible of objective measurement and shall be based solely on one or more
Qualified Performance Criteria. The Committee shall notify each Participant of
the terms of his or her Award.
 
     6.  Determination of Performance Achievements.  As soon as practicable
after the close of each Fiscal Year, the Committee shall determine the extent,
if any, to which the performance goals preestablished with respect to Awards for
such Fiscal Year have been met, and in the case of Awards to Section 162(m)
officers shall certify (in such form as may be required under the regulations
under Section 162(m) of the Code) as to the results of its determination.
 
     7.  Award Payments.
 
          (a) As soon as practicable after the close of each Fiscal Year, but
     not earlier than the determinations and, to the extent applicable,
     certification described in Section 6 above, the Committee shall pay to each
     Participant for the Fiscal Year the amount determined by the Committee to
     have been earned by
 
                                       A-2
<PAGE>   32
 
     the Participant under his or her Award for the Fiscal Year. In determining
     the amount, if any, to be paid under an Award, the Committee may take into
     account such factors (including, without limitation, individual job
     performance or other subjective criteria) as it deems appropriate;
     provided, that the maximum payment under Awards to any Participant for any
     Fiscal Year shall be $1,750,000; and further provided, that in the case of
     an Award to a Section 162(m) officer, payments shall be limited by
     paragraph (b) below. Except as provided at Sections 8 and 9 below, no Award
     Payment shall be made to any Participant who is not employed by the
     Corporation or its subsidiaries at the time of payment.
 
          (b) In the case of an Award to a Section 162(m) officer, Award
     Payments, if any, shall be conditioned on certification by the Committee as
     described in Section 6 above that the objective performance goals (based on
     one or more Qualified Performance Criteria) established by the Committee
     under Section 5 above have been met to the extent required for payment at
     the time such goals were so established. In the absence of such a
     certification no payment shall be made under an Award to a Section 162(m)
     officer. The Committee in its sole discretion may reduce, but not increase,
     the objectively determinable amount that would otherwise be payable to a
     Section 162(m) officer (based on attainment of preestablished performance
     goals), including a reduction to zero, if the Committee determines such
     reduction to be appropriate based on such personal, corporate or other
     factors as the Committee deems appropriate.
 
          (c) Award Payments shall be made in cash or, if so determined by the
     Committee, in shares of restricted common stock of the Corporation issued
     under the Stock Plan or a combination of cash and such restricted common
     stock. Any restricted common stock issued under the Stock Plan shall be
     valued for purposes of applying the $1,750,000 limit described at paragraph
     (a) above at the closing price of the common stock of the Corporation on
     the trading day that immediately precedes the date Award Payments are made
     for the Fiscal Year.
 
     8.  Death or Disability of a Participant.  In the event a Participant dies
or suffers a termination of employment by reason of death or disability after an
Award has been granted to the Participant but before the Award Payment has been
determined and paid, there shall be paid to the Participant (or, in the event of
death, to the Participant's beneficiary or estate) a prorated amount equal to
the Award Payment that the Committee estimates would have been paid to the
Participant had his or her employment continued multiplied by a fraction, the
numerator of which is the number of completed calendar months of employment
during the Fiscal Year and the denominator of which is twelve.
 
     9.  Change in Control.
 
          (a) In the event of a Change in Control, the Corporation shall pay to
     each Eligible Employee who is a Participant with respect to the Fiscal Year
     in which the Change in Control occurs and who is employed by the
     Corporation or its subsidiaries immediately prior to the Change in Control
     an amount equal to the greater of (a) 100% of the Participant's target
     Award Payment for the Fiscal Year in which the Change in Control occurs,
     based on the Participant's base salary as in effect at time of payment or,
     if higher, the Participant's base salary as in effect immediately prior to
     the Change in Control, and (b) if the Change in Control occurs after at
     least six months of the Fiscal Year have elapsed, the amount the
     Participant would have earned under his or her Award for the Fiscal Year
     assuming annualized performance based on performance through the date of
     the Change in Control and assuming no reduction in Award Payments for
     factors other than objective performance factors. In addition, if at the
     time of a Change in Control there has been no determination or payment of
     Award Payments for the preceding Fiscal Year, the Corporation shall pay to
     each individual who was a Participant with respect to such prior Fiscal
     Year the full amount to which he or she would have been paid assuming
     certification by the Committee of the performance for such Fiscal Year and
     assuming no reduction in Award Payments for factors other than objective
     performance factors. Payments under this Section 9 shall be made not later
     than ten (10) days following the Change in Control.
 
                                       A-3
<PAGE>   33
 
          (b) For purposes of the Plan, a Change in Control shall be deemed to
     have occurred if:
 
             (i) any "person," as such term is used in Section 13(d) and 14(d)
        of the Securities Exchange Act of 1934 (the "Exchange Act"), (other than
        the Corporation, any trustee or other fiduciary holding securities under
        an employee benefit plan of the Corporation, or any corporation owned,
        directly or indirectly, by the stockholders of the Corporation in
        substantially the same proportions as their ownership of stock of the
        Corporation), is or becomes the "beneficial owner" (as defined in Rule
        13d-3 under the Exchange Act), directly or indirectly, or securities of
        the Corporation representing 25% or more of the combined voting power of
        the Corporation's then outstanding securities;
 
             (ii) during any period of two consecutive years (not including any
        period prior to the execution of the Plan), individuals who at the
        beginning of such period constitute the Board, and any new director
        (other than a director designated by a person who has entered into an
        agreement with the Corporation to effect a transaction described in
        clause (i), (iii) or (iv) of this Section 9(b)) whose election by the
        Board or nomination for election by the Corporation's stockholders was
        approved by a vote of at least two-thirds ( 2/3) of the directors then
        still in office who either were directors at the beginning of the period
        or whose election or nomination for election was previously so approved
        (hereinafter referred to as "Continuing Directors"), cease for any
        reason to constitute at least a majority thereof;
 
             (iii) the stockholders of the Corporation approve a merger or
        consolidation of the Corporation with any other corporation, other than
        a merger or consolidation which would result in the voting securities of
        the Corporation outstanding immediately prior thereto continuing to
        represent (either by remaining outstanding or by being converted into
        voting securities of the surviving entity) more than 80% of the combined
        voting power of the voting securities of the Corporation or such
        surviving entity outstanding immediately after such merger of
        consolidation; provided, however, that a merger or consolidation
        effected to implement a recapitalization of the Corporation (or similar
        transaction) in which no "person" (as hereinabove defined) acquires more
        than 25% of the combined voting power of the Corporation's then
        outstanding securities shall not constitute a Change in Control of the
        Corporation; or
 
             (iv) the stockholders of the Corporation approve a plan of complete
        liquidation of the Corporation or an agreement for the sale or
        disposition by the Corporation of all or substantially all of the
        Corporation's assets.
 
     10.  Designation of beneficiary.  Each Participant may designate a
beneficiary or beneficiaries to receive any amounts payable to the Participant
under the Plan. Each such designation and any change in such designation shall
be made in writing on a form and in a manner prescribed or approved by the
Committee. In the absence of an effective beneficiary designation, amounts, if
any, that are payable under an Award with respect to a deceased Participant
shall be paid to his or her estate. Notwithstanding the foregoing, the delivery
of any shares of common stock under the Stock Plan shall be limited to and
subject to the terms of the Stock Plan.
 
     11.  Plan not exclusive; effect on employment agreements.  The
establishment of the Plan and the granting of Awards hereunder shall not affect
the right of the Corporation to establish other plans or pay other compensation
or benefits to or for the benefit of Eligible Employees hereunder, subject only
to the proviso that any such other compensation or benefits shall be awarded and
paid in a manner that is consistent with the continued qualification under
Section 162(m) of the Code of Awards hereunder made to Section 162(m) officers.
The Plan shall not be construed as reducing or otherwise adversely affecting any
rights that an Eligible Employee may have to incentive compensation under an
employment agreement with the Corporation.
 
     12.  No employment rights.  Nothing in the Plan or in any Award granted
hereunder shall be construed as conferring on any individual any right to
employment or continued employment with the Corporation or any of its
subsidiaries or as restricting in any way the right of the Corporation to
terminate such individual's
 
                                       A-4
<PAGE>   34
 
employment, nor shall the loss or potential of benefits under any Award be an
element of damages in any claim against the Corporation or its subsidiaries.
 
     13.  Taxes.  All payments under the Plan or any Award shall be reduced by
all taxes and other required withholdings.
 
     14.  Shareholder approval.  The Plan has been established effective as of
January 1, 1998 subject to the approval of the stockholders of the Corporation
at the 1998 Annual Meeting. Awards may be made under the Plan prior to such
approval but shall be subject to such approval.
 
     15.  Amendment and termination.  The Committee or the Board may suspend or
terminate the Plan at any time and may amend the Plan from time to time. No such
action shall affect a Participant's rights to shares of common stock issued
under the Stock Plan except to the extent consistent with the terms of the Stock
Plan.
 
     16.  Construction.  The Plan and Awards under the Plan shall be construed
in accordance with the laws of the Commonwealth of Massachusetts.
