                                   UST CORP.

                         EXECUTIVE EMPLOYMENT AGREEMENT


         This Agreement is made by and between UST Corp., a Massachusetts
corporation, (the "Company") and Suzanne Moot (the "Employee") as of the 1st
day of  September, 1995 (the "Effective Date").

         In consideration of the mutual promises, terms and conditions
contained in this Agreement, the parties agree as follows:

         1.      EMPLOYMENT.  The Company agrees to continue the employment of
the Employee, and the Employee agrees to continue in the service of the
Company, subject to the terms and conditions contained in this Agreement.

         2.      TERM.  Subject to earlier termination, as provided hereafter,
the Employee's employment hereunder shall be for an initial term of two (2)
years, commencing on the Effective Date, and may be renewed thereafter only by
written agreement, signed by the Employee and the Chief Executive Officer of
the Company.  Notwithstanding the foregoing, in the event that this Agreement
is in effect on the date of consummation of a Change of Control, as hereafter
defined, this Agreement shall automatically be extended on said date such that
the remaining term of the Agreement shall then be two (2) years, but this
Agreement shall be renewable thereafter only by a written agreement signed by
the Employee and a duly authorized representative of the Company.  The term of
this Agreement, as from time to time renewed or extended in accordance with
this Section 2, is hereafter referred to as "the term hereof" or "the term of
this Agreement".

         3.      PERFORMANCE.
                 -----------

                 a.   During the term hereof, the Employee shall hold such
executive position or positions with the Company and/or any of its subsidiaries
as may be designated from time to time by the Board of Directors of the Company
(the "Board") and shall perform the duties and assume the responsibilities of
such positions and such other appropriate duties and responsibilities as may be
assigned by the Board or its designees.

                 b.       During employment, the Employee shall devote his/her
full business time and best efforts, judgment, skill and knowledge exclusively
to the advancement of the Company's interests and to the discharge of his/her
duties and responsibilities for the Company.  While employed by the Company,
the Employee shall not be engaged in any other business activity, except as
approved by the Board or its designee in writing.  It is agreed, however, that
the provisions of this Section 3.b shall not be violated by the Employee's
holding of directorships or related positions in charitable, educational or
not-for-profit organizations which do not involve continuous or substantial
time commitments or by passive personal investment activities, provided that
such positions and activities are not in conflict, and do not otherwise
interfere, with the Employee's duties and responsibilities to the Company and
its subsidiaries.
         
   2
         4.      COMPENSATION.  As compensation for all services performed for 
the Company and its subsidiaries during the term of this Agreement, the Company
shall pay the Employee a base salary at an annual rate not less than the
Employee's base salary on the Effective Date, subject to increase from time to
time by the Company in its discretion.  Notwithstanding the foregoing, the
Company may reduce the Employee's base salary, but (i) only in the event of a
salary reduction affecting all or substantially all of the Company's officers
employed under an executive employment agreement and only in proportion to the
salary reductions applicable to such other affected officers and (ii) only if
no Change of Control has occurred.

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

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

                 a.       UPON DEATH.  In the event of the Employee's death
during the term hereof, the Employee's employment hereunder shall immediately
and automatically terminate.  In such event, the Company shall pay to the
Employee's designated beneficiary or, if no beneficiary has been designated by
the Employee, to the Employee's estate, any base salary earned and unpaid
through the date of death.

                 b.       AS A RESULT OF DISABILITY.  In the event that the
Employee becomes disabled during the term hereof and, as a result, is unable to
perform substantially all of his/her duties for the Company for more than one
hundred and twenty (120) days during any period of three hundred and sixty-five
(365) days, the Company may terminate the Employee's employment without further
obligation upon notice to the Employee.  In the event of such disability, the
Employee will continue to receive his/her base salary and benefits under
Sections 4 and 5 hereof until the earlier of the date the Employee becomes
eligible for disability income under the Company's long-term disability or
workers' compensation insurance plan or the date his/her employment terminates.

                 c.       BY THE COMPANY FOR CAUSE.  The Company may terminate
the Employee's employment for Cause at any time upon notice to the Employee
setting forth in reasonable detail the nature of such Cause.  The following, as
determined by the Board in its reasonable judgment, shall constitute Cause for
termination:  (i) the Employee's refusal to perform, or gross negligence in the
performance of, his/her duties or responsibilities on behalf of the Company;
(ii) the Employee's fraud, embezzlement or other material dishonesty with
respect to the Company or any of its subsidiaries; (iii) the Employee's gross
misconduct or his/her conviction of, or plea of no contest to, a felony.  In
the event of such termination, the Company shall have no further obligation to
the Employee, other than for base salary earned through the date of
termination.


                                     -2-
   3
                 d.       BY THE COMPANY OTHER THAN FOR CAUSE.  The Company 
may terminate the Employee's employment other than for Cause at any time upon
notice to the Employee.  In the event of such termination prior to, or more
than two years following, a Change of Control and provided that the Employee
executes the release of claims attached hereto and marked "A" (the "Employee
Release") within twenty-one (21) days of his/her receipt of notice of
termination of employment and does not timely revoke the Employee Release, the
Company shall:

                          i. pay the Employee severance pay in an amount equal
                 to twelve (12) months' base salary at the rate in effect on
                 the date of termination, which the Employee may elect to
                 receive (A) in a single lump sum, payable within thirty (30)
                 days following the effective date of the Employee Release or
                 (B) as salary continuation payable at the Company's regular
                 payroll periods and in accordance with its regular payroll
                 practices commencing on the next regular payday immediately
                 following the effective date of the Employee Release, but
                 retroactive to the date of termination and,

                          ii. (A) if the Employee and/or his/her eligible
                 dependents exercise their right to continue participation in
                 the Company's group health plan under applicable federal law
                 ("COBRA"), then, for the period of twelve (12) months
                 following termination of the Employee's employment or, if
                 earlier, until the date the Employee ceases to be eligible for
                 continued participation under COBRA, the Company shall
                 continue to pay that share of the premium cost of Employee's
                 participation and that of his/her eligible dependents in the
                 Company's group health plan as it pays for active employees of
                 the Company and their eligible dependents generally OR (B) if
                 the Employee and his/her eligible dependents elect not to
                 continue participation in the Company's group health plan
                 under COBRA, the Company will pay the Employee a single lump
                 sum payment equal to the amount that the Company would have
                 expended if participation had been elected and continued for a
                 period of twelve (12) months, which lump sum shall be payable
                 within thirty (30) days following the effective date of the
                 Employee Release, and

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

                 e.       BY THE EMPLOYEE FOR GOOD REASON.  The Employee may
terminate employment hereunder for Good Reason upon notice to the Company
setting forth in reasonable detail the nature of such Good Reason.  The
following shall constitute Good Reason for termination by the Employee:  (i)
failure of the Company to continue the Employee in an executive position; (ii)
material diminution in the nature or scope of the Employee's responsibilities,
duties or authority, other than as is materially consistent with the Employee's
assignment to another executive position; (iii) material failure of the Company
to provide the Employee base salary and benefits in accordance with the terms
of Sections 4 and 5 hereof; or (iv) a permanent transfer of the Employee to a
work site more than twenty-five miles distant from his/her


                                      -3-
   4
work site on the Effective Date.  In the event of termination in accordance
with this Section 6.e, the Company shall provide the Employee base salary and
health insurance benefits in accordance with Section 6.d hereof, provided that
the Employee executes the Employee Release within twenty-one (21) days of
his/her notice of termination of employment and provided further that the
Employee does not timely revoke the Employee Release.

                 f.  BY THE EMPLOYEE OTHER THAN FOR GOOD REASON.  The Employee
may resign employment other than for Good Reason at any time upon one month's
notice to the Company.  In the event of such termination, the Company shall
have no further obligation to the Employee, other than for base salary earned
through the date of termination.

                 g.  Upon a Change of Control.
                     -------------------------

                          (i)  If a Change of Control occurs and, within two (2)
years following such Change of Control, the Company terminates the Employee's
employment other than for Cause, or the Employee terminates his/her employment
for Good Reason, and the Employee executes the Employee Release within
twenty-one (21) days of the date of notice of termination of his/her employment
and does not timely revoke it, then, in lieu of any payment and benefits to
which the Employee would otherwise be entitled under Section 6.d or 6.e hereof,
the Company

                                (1)  shall pay the Employee an amount equal
         to eighteen (18) months' base salary at the rate in effect on the date
         of termination of the Employee's employment, which the Employee may
         elect to receive (A) in a single lump sum, payable within thirty (30)
         days following the effective date of the Employee Release or (B) as
         salary continuation payable at the Company's regular payroll periods
         and in accordance with its regular payroll practices commencing on the
         next regular payday immediately following the final payment under
         Section 6.d or 6.e hereof, whichever is applicable,

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

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

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

                                        (A) any "person", as such term used in
         Section 13(d) and 14(d) of the Securities Exchange Act of 1934 as
         amended (the "Exchange Act") other than the Company or any of its
         subsidiaries or affiliates or any trustee or other fiduciary holding
         securities under an employee benefit plan of the Company or any of its
         subsidiaries or affiliates, becomes a beneficial owner (within the
         meaning of Rule 13d-3, as amended, as promulgated under the Exchange
         Act), directly or indirectly, of securities representing twenty-five
         (25%) percent or more of the combined voting power of the Company's
         then outstanding securities; or

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

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

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

                                        (E) there occurs a closing of a sale or
         other disposition by the Company of all or substantially all of the
         Company's assets.

                 h.       UPON EXPIRATION OF THE TERM HEREOF.  In the event
that the term of this Agreement expires and, at the time of such expiration,
the Company has not offered to extend or renew this Agreement on terms no less
favorable in the aggregate as those set forth herein, then such expiration
shall be treated as a termination by the Company of the Employee's employment
other than for Cause in accordance with Section 6.d hereof.  In the event that
the Company has offered such extension or renewal prior to the expiration of
the term hereof, but such offer has not been accepted by the Employee at the


                                      -5-
   6

time of such expiration, then such expiration shall be treated as a termination
by the Employee of his employment other than for Good Reason.

         7.      CONFIDENTIAL INFORMATION.
                 ------------------------

                 a.       The Employee acknowledges that the Company
continually develops Confidential Information, that the Employee may develop
Confidential Information for the Company and that the Employee may learn of
Confidential Information during the course of employment.  The Employee agrees
to comply with the policies and procedures of the Company for protecting
Confidential Information and agrees that he shall never disclose to any person,
corporation or other entity, except as required for the proper performance of
his/her regular duties for the Company, and shall never use for his/her own
benefit or that of another, any Confidential Information obtained by the
Employee incident to his/her employment or other association with the Company
or any of its affiliates or subsidiaries.  The Employee understands that this
restriction will continue to apply throughout his/her employment and after
his/her employment terminates, regardless of the reason for such termination.

                 b.       As used in this Agreement, "Confidential Information"
means any and all information of the Company, its subsidiaries and affiliates,
that is not generally known by others with whom any of them competes or does
business, or with whom any of them plans to compete or do business, including
without limitation any and all information concerning the identity and special
needs of the customers of the Company, its subsidiaries and affiliates and the
people and organizations with whom any of them has business relationships and
those relationships.  Confidential Information also includes any information
received by the Company or any of its subsidiaries or affiliates from others
with any understanding, express or implied, that it will not be disclosed.

         8.      NON-SOLICITATION.  While the Employee is employed by the
Company and for a period of two years thereafter, the Employee shall not,
directly or indirectly, solicit or encourage any customer of the Company or any
of its subsidiaries or affiliates to terminate or diminish its relationship
with the Company or any of its subsidiaries or affiliates, or to conduct with
any person, corporation or other entity any business or activity which such
customer conducts or could conduct with the Company or any of its subsidiaries
or affiliates, nor shall the Employee conduct, on his/her own behalf or that of
another, any such business or activity with a customer of the Company or any of
its subsidiaries or affiliates.

         9.      REMEDIES.  The Employee acknowledges that, if he/she were to
breach any of the provisions of Section 7 or Section 8 of this Agreement, the
harm to the Company would be irreparable.  The Employee therefore agrees that,
in addition to any other remedies available to it, the Company shall be
entitled to obtain preliminary and permanent injunctive relief against any such
breach, without having to post bond.

         10.     TAXES.  All payments made to the Employee under this Agreement
shall be reduced by any tax or other amount required to be withheld by the
Company under applicable law.

         11.     REDUCTIONS.  Notwithstanding anything to the contrary
contained in this Agreement, (a) any and all payments and benefits to be
provided to the Employee hereunder are subject to reduction to


                                      -6-
   7

the extent required by applicable statutes, regulations, rules and directives
of federal, state and other governmental and regulatory bodies having
jurisdiction over the Company and/or any of its affiliates or subsidiaries and
(b) the payments and benefits to which the Employee would be entitled pursuant
to Section 6.g hereof or otherwise as a result of a Change of Control shall be
reduced to the maximum amount for which the Company will not be limited in its
deduction pursuant to Section 280G of the Internal Revenue Code of 1986, as
amended, or any successor provision.  Any such reduction shall be applied to
the amounts due to the Employee in such manner as the Employee may reasonably
specify within thirty (30) days following notice from the Company of the need
for such reduction or, if the Employee fails to so specify timely, as
determined by the Company.

         12.     ASSIGNMENT.  The Company may assign its rights and obligations
under this Agreement without the consent of the Employee in the event that the
Company shall hereafter effect a reorganization, consolidate with, or merge
into, any other person, corporation or other entity or transfer all or
substantially all of its assets to any other person, corporation or other
entity.  The Company requires the personal services of the Employee and he/she
may not assign this Agreement.  This Agreement shall inure to the benefit of
and be binding upon the Company and the Employee and their respective
successors, executors, administrators, heirs and permitted assigns.

         13.     MISCELLANEOUS.  This Agreement sets forth the entire agreement
between the Company and the Employee and supersedes all prior communications,
agreements and understandings, whether written or oral, with respect to the
Employee's employment.  The headings and captions contained herein are for
convenience of reference only and are not part of this Agreement.  This
Agreement may not be modified or amended, its term may not be extended or
renewed, and no breach of this Agreement shall be deemed to be waived, unless
agreed to in writing by the Employee and the Company.  This is a Massachusetts
contract and shall be governed by and construed in accordance with the laws of
the Commonwealth of Massachusetts.

         14.     NOTICES.  Any notices provided for in this Agreement shall be
in writing and shall be effective when delivered in person or deposited in the
United States mail, postage prepaid, and addressed to the Employee at his last
known address on the books of the Company or, in the case of the Company, at
its main office, attention of the Senior Vice President, Human Resources with a
