         (i)     UST Corp. adopts Stock Purchase Rights Plan
                 -------------------------------------------

         On September 19, 1995, the Board of Directors of UST Corp. (the
"Company") declared a dividend distribution of one preferred share purchase
right (a "Right") for each outstanding share of common stock, par value $0.625
per share (the "Common Shares"), of the Company.  The dividend is payable on
October 6, 1995 (the "Record Date") to the stockholders of record on that date.
Except as described below, each Right, when exercisable, entitles the
registered holder to purchase from the Company one one- hundredth of a share of
Series A Junior Participating Preferred Stock, par value $1.00 per share (the
"Preferred Shares"), of the Company at a price of $40 per one one-hundredth of
a Preferred Share (the "Purchase Price"), subject to adjustment.  The
description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") between the Company and United States Trust Company, as
Rights Agent (the "Rights Agent").

         Initially, the Rights will be attached to all certificates
representing Common Shares then outstanding, and no separate Rights
certificates will be distributed.  Until the earlier to occur of (i) 10
business days following a public announcement that a person or group of
affiliated or associated persons (an "Acquiring Person") have acquired
beneficial ownership of 15% or more of the outstanding Common Shares (the date
of such an announcement being a "Shares Acquisition Date"), (ii) 10 business
days (or such later date as may be determined by action of the Board of
Directors prior to such time as any Person becomes an Acquiring Person)
following the commencement of, or announcement of an intention to make, a
tender offer or exchange offer the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of such outstanding
Common Shares or (iii) the declaration by the Board of Directors of the Company
that any person is an "Adverse Person" (the earliest of such dates being called
the "Distribution Date"), the Rights will be evidenced, with respect to any of
the Common Share certificates outstanding as of the Record Date, by such Common
Share certificate together with a copy of this Summary of Rights.

         The Board of Directors of the Company may declare a person to be an
Adverse Person, after a determination that such person, alone or together with
its affiliates and associates, has become the beneficial owner of 10% or more
of the outstanding Common Shares and a determination by the Board of Directors,
after reasonable inquiry and investigation, that (a) such beneficial ownership
by such person is intended or reasonably likely to cause the Company to
repurchase the Common Shares beneficially owned by such





   3
                                      -2-




person or to cause pressure on the Company to take action or enter into a
transaction or series of transactions which would provide such person with
short-term financial gain under circumstances where the Board of Directors
determines that the best long-term interests of the Company and its
stockholders would not be served by taking such action or entering into such
transactions at that time or (b) such beneficial ownership is causing or
reasonably likely to cause a material adverse impact on the business or
prospects of the Company.  However, the Board of Directors of the Company may
not declare a person to be an Adverse Person if, prior to the time that such
person acquired 10% or more of the Common Shares then outstanding, such person
provided to the Board of Directors in writing a statement of such person's
purpose and intentions in connection with the proposed acquisition requested of
such person by the Board of Directors, and the Board of Directors, based on
such statement and reasonable inquiry and investigation, notifies such person
in writing that it will not declare such person to be an Adverse Person;
provided, however, that the Board of Directors may expressly condition in any
manner a determination not to declare a person an Adverse Person on such
conditions as the Board of Directors may select, including without limitation,
such person's not acquiring more than a specified amount of stock and/or on
such person's not taking actions inconsistent with the purposes and intentions
disclosed by such person in the statement provided to the Board of Directors.
No delay or failure by the Board of Directors to declare a person to be an
Adverse Person shall in any way waive or otherwise affect the power of the
Board of Directors subsequently to declare a person to be an Adverse Person.
In the event that the Board of Directors should at any time determine, upon
reasonable inquiry and investigation, that such person has not met or complied
with any condition specified by the Board of Directors, the Board of Directors
may at any time thereafter declare such person to be an Adverse Person.

         The Rights Agreement provides that, until the Distribution Date, the
Rights will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the Record Date upon transfer or new
issuance of Common Shares will contain a notation incorporating the Rights
Agreement by reference.  Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any certificates for
Common Shares outstanding as of the Record Date, even without such notation or
a copy of this Summary of Rights being attached thereto, will also constitute
the transfer of the Rights associated with the Common Shares represented by
such certificate.  As soon as practicable following the Distribution Date,
separate certificates evidencing the Rights ("Rights Certificates") will be
mailed to holders of record of the Common





   4
                                      -3-




Shares as of the close of business on the Distribution Date, and the separate
Rights Certificates alone will evidence the Rights.

         The Rights are not exercisable until the Distribution Date.  The
Rights will expire on October 6, 2005 (the "Final Expiration Date"), unless the
Rights are earlier redeemed by the Company, as described below.

         The Purchase Price payable, and the number of Preferred Shares or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the
Preferred Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred Shares at a
price, or securities convertible into Preferred Shares with a conversion price,
less than the then current market price of the Preferred Shares or (iii) upon
the distribution to holders of the Preferred Shares of evidences of
indebtedness or assets (excluding regular periodic cash dividends paid out of
earnings or retained earnings or dividends payable in Preferred Shares) or of
subscription rights or warrants (other than those referred to above).

         The number of outstanding Rights and the number of one one-hundredths
of a Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Shares or a stock
dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such
case, prior to the Distribution Date.

         Preferred Shares purchasable upon exercise of the Rights will not be
redeemable.  Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment of $1 per share but will be entitled to an aggregate
dividend of 100 times the dividend declared per Common Share.  In the event of
liquidation, the holders of the Preferred Shares will be entitled to a minimum
preferential liquidation payment of $100 per share but will be entitled to an
aggregate payment of 100 times the payment made per Common Share.  Each
Preferred Share will have 100 votes, voting together with the Common Shares.
Finally, in the event of any merger, consolidation or other transaction in
which Common Shares are exchanged, each Preferred Share will be entitled to
receive 100 times the amount received per Common Share.  These rights are
protected by customary antidilution provisions.

         Because of the nature of the Preferred Shares' dividend, liquidation
and voting rights, the value of the one one-hundredth interest in a Preferred





   5
                                      -4-




Share purchasable upon exercise of each Right should approximate the value of
one Common Share.

         In the event that, after the first date of public announcement by the
Company or an Acquiring Person that an Acquiring Person has become such, the
Company is involved in a merger or other business combination transaction in
which the Common Shares are exchanged or changed, or 50% or more of the
Company's consolidated assets or earning power are sold (in one transaction or
a series of transactions), proper provision will be made so that each holder of
a Right (other than an Acquiring Person or an Adverse Person) will thereafter
have the right to receive, upon the exercise thereof at the then current
exercise price of the Right, that number of shares of common stock of the
acquiring company (or, in the event there is more than one acquiring company,
the acquiring company receiving the greatest portion of the assets or earning
power transferred) which at the time of such transaction would have a market
value of two times the exercise price of the Right.

         In the event that (i) any person becomes an Acquiring Person, (ii) an
Acquiring Person or Adverse Person engages in one or more "self-dealing"
transactions as set forth in the Rights Agreement, (iii) during such time as
there is an Acquiring Person or Adverse Person, there shall be a
reclassification of securities or a recapitalization or reorganization of the
Company or other transaction or series of transactions involving the Company
which has the effect of increasing by more than 1% the proportionate share of
the outstanding shares of any class of equity securities of the Company or any
of its subsidiaries beneficially owned by the Acquiring Person, or (iv) the
Board of Directors shall determine that a person is an Adverse Person, proper
provision shall be made so that each holder of a Right, other than Rights
beneficially owned by any Acquiring Person or Adverse Person, will thereafter
have the right to receive upon exercise that number of Common Shares having a
market value of two times the exercise price of the Right.  UPON OCCURRENCE OF
ANY OF THE EVENTS DESCRIBED IN THE IMMEDIATELY PRECEDING SENTENCE, ANY RIGHTS
THAT ARE, OR (UNDER CERTAIN CIRCUMSTANCES SPECIFIED IN THE RIGHTS AGREEMENT)
WERE, BENEFICIALLY OWNED BY ANY ACQUIRING PERSON OR ADVERSE PERSON SHALL
IMMEDIATELY BECOME NULL AND VOID.  At any time after the occurrence of any such
event and prior to the acquisition by any person or group of 50% or more of the
outstanding Common Shares, the Continuing Directors may exchange the Rights
(other than Rights owned by such person or group which have become void), in
whole or in part, at an exchange ratio of one Common Share, or one
one-hundredth of a Preferred Share (or of a share of a class or series of the
Company's preferred stock having equivalent rights, preferences and
privileges), per Right (subject to adjustment).





   6
                                      -5-




         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depository
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

         At any time prior to the earlier of (i) the tenth day after a Shares
Acquisition Date, (ii) the declaration by the Board of Directors that a person
is an Adverse Person or (iii) the expiration of the Rights, the Board of
Directors may redeem the Rights in whole, but not in part, at a price of $.001
per Right (the "Redemption Price").  Under certain circumstances set forth in
the Rights Agreement, such a redemption would require the concurrence of the
Company's "Continuing Directors", that is, any director who is not an Acquiring
Person, an Adverse Person or an affiliate or associate of an Acquiring Person
or Adverse Person, and who was in office prior to the date of the Rights
Agreement or subsequently nominated by a majority of the Continuing Directors.
Thereafter, the Rights may only be redeemed by the Continuing Directors in
whole, but not in part, at the Redemption Price, (a) under certain
circumstances described in the Rights Agreement involving a disposition of
Common Shares by the Acquiring Person or Adverse Person such that such person's
common share ownership is reduced to 10% or less, or (b) if such redemption is
incidental to a merger or other business combination transaction or series of
transactions involving the Company but not involving an Acquiring Person or an
Adverse Person and satisfying certain other conditions.  The redemption of the
rights may be made effective at such time on such basis and with such
conditions as the Board of Directors or the Continuing Directors, as the case
may be, in their sole discretion may establish.  Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only right of the holders of Rights will be to receive the Redemption
Price.

         Other than those provisions relating to the principal economic terms
of the Rights, any of the provisions of the Rights Agreement may be amended by
the Board of Directors of the Company prior to the Distribution Date.  After
the Distribution Date, the provisions of the Rights Agreement may be amended by
the Board (in certain circumstances, with the concurrence of the Continuing
Directors) in order to cure any ambiguity, to make changes that do not
adversely affect the interests of holders of Rights (excluding the interests of
any Acquiring Person or Adverse Person), or to shorten or lengthen any time
period under the Rights Agreement; provided,





   7
                                      -6-




however, that no amendment to adjust the time period governing redemption shall
be made at such time as the Rights are not redeemable.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends.

         The Rights could have certain anti-takeover effects.  The Rights could
cause substantial dilution to a person or group that attempts to acquire the
Company on terms not approved by the Company's Board of Directors.  The Rights
should not interfere with any merger or other business combination approved by
the Board of Directors, in light of the ability of the Board of Directors to
redeem the Rights or amend the Rights Agreement as summarized above.

         The form of Rights Agreement between the Company and the Rights Agent
specifying the terms of the Rights, which includes as Exhibit B the form of
Rights Certificate, is filed as an exhibit hereto (through incorporation by
reference of an exhibit to a Registration Statement on Form 8-A of the Company)
and incorporated herein by reference.  The foregoing description of the Rights
does not purport to be complete and is qualified in its entirety by reference
to the Rights Agreement.
